    To determine the expression of autistic and positive schizotypal traits in a large sample of adults with bipolar I disorder (BD I), and the effect of co-occurring autistic and positive schizotypal traits on global functioning in BD I. Autistic and positive schizotypal traits were self-assessed in 797 individuals with BD-I recruited by the Bipolar Disorder Research Network. Differences in global functioning (rated using the Global Assessment Scale) during lifetime worst depressive and manic episodes (GASD and GASM respectively) were calculated in groups with high/low autistic and positive schizotypal traits. Regression analyses assessed the interactive effect of autistic and positive schizotypal traits on global functioning. 47.2% (CI=43.7-50.7%) showed clinically significant levels of autistic traits, and 23.22% (95% CI=20.29-26.14) showed clinically significant levels of positive schizotypal traits. In the worst episode of mania, the high autistic, high positive schizotypal group had better global functioning compared to the other groups. Individual differences analyses showed that high levels of both traits were associated with better global functioning in both mood states. Autistic and schizotypal traits were assessed using self-rated questionnaires. Expression of autistic and schizotypal traits in adults with BD I is prevalent, and may be important to predict illness aetiology, prognosis, and diagnostic practices in this population. Future work should focus on replicating these findings in independent samples, and on the biological and/or psychosocial mechanisms underlying better global functioning in those who have high levels of both autistic and positive schizotypal traits.

  2. Measuring ambivalence to science

    Science.gov (United States)

    Gardner, P. L.

    Ambivalence is a psychological state in which a person holds mixed feelings (positive and negative) towards some psychological object. Standard methods of attitude measurement, such as Likert and semantic differential scales, ignore the possibility of ambivalence; ambivalent responses cannot be distinguished from neutral ones. This neglect arises out of an assumption that positive and negative affects towards a particular psychological object are bipolar, i.e., unidimensional in opposite directions. This assumption is frequently untenable. Conventional item statistics and measures of test internal consistency are ineffective as checks on this assumption; it is possible for a scale to be multidimensional and still display apparent internal consistency. Factor analysis is a more effective procedure. Methods of measuring ambivalence are suggested, and implications for research are discussed.

    Ambivalence is a state of inconsistency that is often experienced as affectively aversive. In this functional magnetic resonance imaging study, we investigated the role of cognitive and social-affective processes in the experience of ambivalence and coping with its negative consequences. We examined participants' brain activity during the dichotomous evaluation (pro vs contra) of pretested ambivalent (e.g. alcohol), positive (e.g. happiness) and negative (e.g. genocide) word stimuli. We manipulated evaluation relevance by varying the probability of evaluation consequences, under the hypothesis that ambivalence is experienced as more negative when outcomes are relevant. When making ambivalent evaluations, more activity was found in the anterior cingulate cortex, the insula, the temporal parietal junction (TPJ) and the posterior cingulate cortex (PCC)/precuneus, for both high and low evaluation relevance. After statistically conservative corrections, activity in the TPJ and PCC/precuneus was negatively correlated with experienced ambivalence after scanning, as measured by Priester and Petty's felt ambivalence scale (1996). The findings show that cognitive and social-affective brain areas are involved in the experience of ambivalence. However, these networks are differently associated with subsequent reduction of ambivalence, thus highlighting the importance of understanding both cognitive and affective processes involved in ambivalent decision-making. © The Author (2013).

    Autism spectrum and schizophrenia spectrum disorders are classified separately in the DSM-5, yet research indicates that these two disorders share overlapping features. The aim of the present study was to examine the overlap between autistic and schizotypal personality traits and whether anxiety and depression act as confounding variables in this relationship within a non-clinical population. One hundred and forty-four adults completed the Autism Spectrum Quotient and the Schizotypal Personality Questionnaire and the Depression Anxiety Stress Scales-21. A number of associations were seen between autistic and schizotypal personality traits. However, negative traits were the only schizotypal feature to uniquely predict global autistic traits, thus highlighting the importance of interpersonal qualities in the overlap of autistic and schizotypal characteristics. The inclusion of anxiety and depression did not alter relationships between autistic and schizotypal traits, indicating that anxiety and depression are not confounders of this relationship. These findings have important implications for the conceptualisation of both disorders. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    The concept of schizotypal personality disorder has been heavily discussed since its introduction into the official classification of mental disorders in DSM-III. The aim of this study was to investigate the difference between schizotypal personality disorder within and outside the genetic spectrum of schizophrenia. Schizotypals with and without schizophrenic cotwins and first-degree relatives were compared, with individuals with other mental disorders and no mental disorders as controls. It appeared that only inadequate rapport and odd communication were more pronounced among schizotypals within, compared to schizotypals outside the schizophrenic spectrum. Schizotypals outside the schizophrenic spectrum, however, scored higher than schizotypals inside the schizophrenic spectrum on ideas of reference, suspiciousness, paranoia, social anxiety, self-damaging acts, chronic anger, free-floating anxiety and sensitivity to rejection. Interestingly, the four last features are seldom observed among schizotypals inside the schizophrenic spectrum. Monozygotic non-schizophrenic cotwins of schizophrenics score high on inadequate rapport, odd communication, social isolation and delusions/hallucinations. Monozygotic non-schizophrenic cotwins of schizotypals outside the schizophrenic genetic spectrum score high on illusions, depersonalization, derealization and magical thinking. Negative schizotypal features appear to be inside the schizophrenic spectrum, while positive borderline-like features are outside having another genetic endowment.

    Abstract Background While it has been repeatedly documented that people with schizophrenia report higher levels of adverse events in childhood (emotional, physical and sexual abuse), this has not been extensively examined in healthy individuals who score highly on schizotypal personality traits. The continuum hypothesis of psychosis and schizophrenia suggests it is important to assess the relationship in those who are healthy but who experience some psychotic-like symptoms. Of course, it is problematic to rely upon the veracity of events that anyone might recall from their childhood, but this is likely to be compounded by the presence of well-documented memory and executive problems, as well as symptoms such as delusional thinking, in some adults with psychosis. One advantage of examining healthy participants is that recall is not affected by the condition itself or memory- and executive-function problems. As there is evidence that the expression of psychotic disorders differ between males and females, the etiological mechanisms and pathways to the development and experience of psychotic symptoms may equally differ. Indeed, sex differences in the association between childhood trauma and psychotic symptoms have been noted. The aim of this present study was to investigate any links between childhood trauma and psychotic-like symptoms in healthy individuals. Based on previous research the expectation is that associations will be found between self-reports of childhood trauma and schizotypal personality traits. These associations would be expected to differ between males and females. Methods The sample consisted of 320 participants (221 females, 99 males) with a mean age of 28.24 (SD 12.76). Childhood traumatic events were assessed by three sub-scales (Physical Punishment; Emotional Abuse; and Sexual Events) of the Early Trauma Inventory Self Report-Short Form (ETISR-SF; Bremner et al., 2007). Schizotypal personality traits were assessed using the Five Factor

    Full Text Available In the present research we explored the presence of schizotypal traits in painters. Furthermore, the relations of schizotypy and creativity-related variables (intelligence, creativity and creative productivity were analyzed. Study participants were divided into the criterion (132 students of art academy and art high school and control group (119 psychology students and members of grammar school. Two hypotheses were set: 1 schizotypal traits are more pronounced in painters than in control group; 2 schizotypy is more closely associated with the creativitylinked variables in the criterion than in control group. Schizotypy was operationalized by Disintegration construct and measured via DELTA 10 inventory. Intelligence was assessed by Advanced Progressive Matrices-18; creativity was measured by the same labeled scale from HEXACO-PI-R inventory and creative productivity was explored by a set of questions regarding the frequency of creative behavior. Results showed that Magical thinking, Enhanced awareness, Somatoform Dysregulation, Perceptual distortions and Social anhedonia were the schizotypal traits which were more pronounced in painters as compared to the control group. Factor analyses performed in each group separately revealed a latent component loaded both with schizotypal traits, creativity and creative productivity, but only in the group of painters: schizotypy and creativity were not so closely related in the control group. Thus, the study hypotheses were largely confirmed. Results provide a more detailed understanding of the relations between schizotypy and creativity.

    Ambivalence is widely assumed to prolong grief. To examine this hypothesis, the authors developed a measure of ambivalence based on an algorithmic combination of separate positive and negative evaluations of one's spouse. Preliminary construct validity was evidenced in relation to emotional difficulties and to facial expressions of emotion. Bereaved participants, relative to a nonbereaved comparison sample, recollected their relationships as better adjusted but were more ambivalent. Ambivalence about spouses was generally associated with increased distress and poorer perceived health but did not predict long-term grief outcome once initial outcome was controlled. In contrast, initial grief and distress predicted increased ambivalence and decreased Dyadic Adjustment Scale scores at 14 months postloss, regardless of initial scores on these measures. Limitations and implications of the findings are discussed.

    This study examined whether early or late processes in semantic networks were abnormal in women with a diagnosis of schizotypal personality disorder. The N400 component of the EEG event-related potentials was used as a probe of semantic processes. Word pairs were presented with short and long stimulus-onset asynchronies to investigate, respectively, early and late semantic processes in 16 women with schizotypal personality disorder and 15 normal female comparison subjects. Event-related potentials were recorded in response to the last words in a pair. With the short stimulus-onset asynchrony, the N400 amplitude was less negative in the schizotypal personality disorder group than in the normal comparison group. No group differences were found with the long stimulus-onset asynchrony. The finding of a less negative than normal N400 amplitude with the short stimulus-onset asynchrony in women with schizotypal personality disorder supports the hypothesis that persons with this disorder evince an overactivation of semantic networks. The absence of group differences with the long stimulus-onset asynchrony, which is primarily sensitive to processes involved in context integration, suggests that in this group of schizotypal personality disorder subjects, additional demands on working memory may be necessary to bring out the semantic dysfunction.

    Schizotypal personality disorder is characterized by social and interpersonal deficits marked by discomfort with, and reduced capacity for, close relationships as well as by cognitive or perceptual distortions and eccentricities of behavior. Inappropriate or constricted affect, reduced capacity for relationships, lack of close friends and reduced capacity for social life are the symptoms that overlap both schizotypal personality disorder and autism spectrum disorders. The making of differential diagnosis may be difficult since several symptoms are similar between these disorders. In this study, we discussed the differential diagnosis issues on the basis of an adolescent case. Odd appearance, magical thoughts, reference thoughts suggests Schizotypal Personality Disorder whereas lack of eye contact at 2 years old, a preference to be isolated and play alone and referral to a child psychiatrist at 4 years old suggest Autism Spectrum Disorders. Based on the results of psychological assessment, Wechsler Intelligence Scale for Children-Revised (WISC-R) profile is compatible with autistic children's profiles. Based on Schizotypal Personality Questionnaire, the patient's anxiety, lack of close friends, constricted affect symptoms which take place in the category of interpersonal schizotypy seems to overlap with lack of communication of Autism Spectrum Disorders. This case report indicates that, separation of autism and schizophrenia, a very important historical breakthrough in autism research, may be blurred in cases with less typical clinical pictures representing autistic and schizophrenic "spectrum" diagnosis.

    This study addresses the unraveling of the relationship between autism spectrum and schizophrenia spectrum traits in a population of adolescents with Autism Spectrum Disorders (ASD). Recent studies comparing isolated symptoms of both spectrum disorders as well as diagnostic criteria for each (DSM-IV-TR) suggest resemblances in the clinical phenotype. A group of 27 adolescents with ASD (11 to 18 years) and 30 typically developing adolescents, matched for age and gender, participated in this study. Within the ASD group 11 adolescents satisfied DSM-IV-TR criteria for schizotypal personality disorders. Autistic and schizotypal traits were identified by means of well validated questionnaires (Autism Questionnaire, AQ and Schizotypal Personality Questionnaire-Revised, SPQ). Significantly more schizotypal traits in adolescents with ASD were found than in typically developing controls. Besides high levels of negative symptoms, adolescents with ASD also displayed high levels of positive and disorganized symptoms. There appeared to be a relationship between the mean level of autistic symptoms and schizotypal traits, as well as specific associations between autistic symptoms and negative, disorganized and positive schizotypal symptoms within individuals. Schizotypal symptomatology in all sub dimensions that are reflected by the SPQ scores, was most prominently associated with attention switching problems of the autism symptoms from the AQ. These findings indicate that patients diagnosed with an ASD show schizophrenia spectrum traits in adolescence. Although other studies have provided empirical support for this overlap in diagnostic criteria between both spectrum disorders, the present findings add to the literature that behavioral overlap is not limited to negative schizotypal symptoms, but extends to disorganized and positive symptoms as well.

    It was examined how juvenile psychiatric disorders and adult schizotypal symptoms are associated. 731 patients of the Department of Child and Adolescent Psychiatry of the University Medical Centre Utrecht, the Netherlands, with mean age of 12.1 years (SD = 4.0) were reassessed at the mean age of 27.9 years (SD = 5.7) for adult schizotypal symptoms using the Schizotypal Personality Questionnaire-Revised (Vollema, Schizophr Bull 26(3):565-575, 2000). Differences between 13 juvenile DSM categories and normal controls (n = 80) on adult schizotypal total and factor scores were analyzed, using (M)ANCOVA. Pervasive developmental disorders (PDD), attention deficit hyperactivity disorders (ADHD), deferred diagnosis, sexual and gender identity disorders and depressive disorders had higher SPQ total scores when compared to normal controls (p gender identity disorders, depressive disorders, disruptive disorders, and the category of 'Other conditions that may be a focus of clinical attention' (p < 0.001). No differences with normal controls were found for adult positive schizotypal symptoms (p < 0.110). The current findings are suggestive of the idea that psychiatric disorders in childhood or adolescence are a more general expression of a liability to schizophrenia spectrum pathology in future life. In addition, specific patterns of adult schizotypal symptomatology are associated with different types of juvenile psychiatric disorder.

    The link between personality and the interest of individuals for science has not been thoroughly explored. In this report, we studied psychopathological traits in students studying science in French top-ranking institutions. Three hundred and forty seven individuals answered questionnaires assessing autistic and schizotypal dimensions, as well as anxiety, depression symptomatology and attachment quality. A cluster analysis based on autistic and schizotypal traits led to the identification of 4 distinct profiles: a "low trait cluster", a "moderate autistic trait cluster", a "moderate schizotypal trait cluster" and a "high trait cluster" (HTC) composed of individuals with high scores on both autistic and schizotypal scales. Each cluster represented 20.1-27.1% of participants and was clearly different from the three others, both on autistic and on schizotypal dimensions. These groups could be also typified by their level of anxiety, depression or degraded attachment, which are proportional to the extent of psychopathological traits. Moreover, students from the HTC cluster displayed lower academic results, thus implying that autistic traits might impair success in science when they are associated with moderate schizotypal personality features. This study also suggests that depression and anxiety might mediate performance inhibition in the HTC group. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available OBJECTIVES: The First Episode Social Functioning Scale (FESFS was designed to measure social functioning of young individuals with schizophrenia. The aim of this study was to validate a Chinese version of the FESFS in a sample of young Chinese adults. METHOD: The FESFS was translated to Chinese prior to being administered to 1576 college students. The factor structure, reliability, and validity of the scale were examined. RESULTS: Two items were deleted after item analysis and the internal consistency of the whole scale was .89. A six-factor structure was derived by exploratory factor analysis. The factors were interpersonal, family and friends, school, living skills, intimacy, and balance. Estimates of the structural equation model supported this structure, with Goodness of Fit Chi-Square χ(2 = 1097.53 (p<0.0001, the root mean square error of approximation (RMSEA = 0.058, and the comparative fit index (CFI = 0.93. Scale validity was supported by significant correlations between social functioning factors scores and schizophrenia personality questionnaire (SPQ scores. Individuals with schizotypal personality features presented poorer social functioning than those without schizotypal personality features. CONCLUSIONS: The Chinese revised version of the FESFS was found to have good psychometric properties and could be used in the future to examine social functioning in Chinese college students.

  3. The influence of schizotypal traits on attention under high perceptual load.

    Schizophrenia Spectrum Disorders (SSD) are known to be characterised by abnormalities in attentional processes, but there are inconsistencies in the literature that remain unresolved. This article considers whether perceptual resource limitations play a role in moderating attentional abnormalities in SSD. According to perceptual load theory, perceptual resource limitations can lead to attenuated or superior performance on dual-task paradigms depending on whether participants are required to process, or attempt to ignore, secondary stimuli. If SSD is associated with perceptual resource limitations, and if it represents the extreme end of an otherwise normally distributed neuropsychological phenotype, schizotypal traits in the general population should lead to disproportionate performance costs on dual-task paradigms as a function of the perceptual task demands. To test this prediction, schizotypal traits were quantified via the Schizotypal Personality Questionnaire (SPQ) in 74 healthy volunteers, who also completed a dual-task signal detection paradigm that required participants to detect central and peripheral stimuli across conditions that varied in the overall number of stimuli presented. The results confirmed decreasing performance as the perceptual load of the task increased. More importantly, significant correlations between SPQ scores and task performance confirmed that increased schizotypal traits, particularly in the cognitive-perceptual domain, are associated with greater performance decrements under increasing perceptual load. These results confirm that attentional difficulties associated with SSD extend sub-clinically into the general population and suggest that cognitive-perceptual schizotypal traits may represent a risk factor for difficulties in the regulation of attention under increasing perceptual load.

    The authors tested whether neural synchronization deficits were present in subjects with schizophrenia and schizotypal personality disorder. Amplitude-modulated tones were used to evaluate auditory steady-state evoked potential entrainment in a combined group of 21 subjects with schizophrenia or schizoaffective disorder, 11 subjects with schizotypal personality disorder, and 22 nonpsychiatric comparison subjects. The schizophrenia or schizoaffective disorder group exhibited decreased power compared to the schizotypal personality disorder and nonpsychiatric comparison groups. There were no differences between groups in N100 amplitude. Subjects with schizophrenia but not subjects with schizotypal personality disorder have deficits in steady-state responses to periodic stimuli, despite an intact response to sensory-evoked potentials (N100). These deficits reflect aberrant neural synchronization or resolution and may contribute to disturbed perceptual and cognitive integration in schizophrenia.

    Understanding the role of substance use disorders in conversion from schizotypal disorder to schizophrenia may provide physicians and psychiatrists with important tools for prevention or early detection of schizophrenia. To investigate whether substance use disorders, in particular cannabis use disorder, are associated with conversion to schizophrenia in individuals with schizotypal disorder. This prospective cohort study included a population-based sample of all individuals born in Denmark from January 1, 1981, through August 10, 2014, with an incident diagnosis of schizotypal disorder and without a previous diagnosis of schizophrenia. Follow-up was completed on August 10, 2014, and data were analyzed from March 10, 2017, through February 15, 2018. Information on substance use disorders combined from 5 different registers. Cox proportional hazards regression using time-varying information on substance use disorders and receipt of antipsychotics and adjusted for parental history of mental disorders, sex, birth year, and calendar year were used to estimate hazard ratios (HRs) and 95% CIs for conversion to schizophrenia. A total of 2539 participants with incident schizotypal disorder were identified (1448 men [57.0%] and 1091 women [43.0%]; mean [SD] age, 20.9 [4.4] years). After 2 years, 16.3% (95% CI, 14.8%-17.8%) experienced conversion to schizophrenia. After 20 years, the conversion rate was 33.1% (95% CI, 29.3%-37.3%) overall and 58.2% (95% CI, 44.8%-72.2%) among those with cannabis use disorders. In fully adjusted models, any substance use disorder was associated with conversion to schizophrenia (HR, 1.34; 95% CI, 1.11-1.63). When data were stratified by substance, cannabis use disorders (HR, 1.30; 95% CI, 1.01-1.68), amphetamine use disorders (HR, 1.90; 95% CI, 1.14-3.17), and opioid use disorders (HR, 2.74; 95% CI, 1.38-5.45) were associated with conversion to schizophrenia. These associations were not explained by concurrent use of antipsychotics, functional

    Schizotypal personality traits are associated with schizophrenia spectrum disorders, and individuals with schizophrenia spectrum disorders demonstrate increased dopamine transmission in the striatum. The authors sought to determine whether individual differences in normal variation in schizotypal traits are correlated with dopamine transmission in the striatum and in extrastriatal brain regions. Sixty-three healthy volunteers with no history of psychiatric illness completed the Schizotypal Personality Questionnaire and underwent positron emission tomography imaging with [(18)F]fallypride at baseline and after administration of oral d-amphetamine (0.43 mg/kg). Dopamine release, quantified by subtracting each participant's d-amphetamine scan from his or her baseline scan, was correlated with Schizotypal Personality Questionnaire total and factor scores using region-of-interest and voxel-wise analyses. Dopamine release in the striatum was positively correlated with overall schizotypal traits. The association was especially robust in the associative subdivision of the striatum. Voxel-wise analyses identified additional correlations between dopamine release and schizotypal traits in the left middle frontal gyrus and left supramarginal gyrus. Exploratory analyses of Schizotypal Personality Questionnaire factor scores revealed correlations between dopamine release and disorganized schizotypal traits in the striatum, thalamus, medial prefrontal cortex, temporal lobe, insula, and inferior frontal cortex. The association between dopamine signaling and psychosis phenotypes extends to individual differences in normal variation in schizotypal traits and involves dopamine transmission in both striatal and extrastriatal brain regions. Amphetamine-induced dopamine release may be a useful endophenotype for investigating the genetic basis of schizophrenia spectrum disorders.

    How school-associated behavioral problems in childhood and adolescence precede distinctive adult schizotypal symptoms was examined. Gender specific findings were explored. After 11.6 (SD = 3.1) years, 159 patients of the Department of Child and Adolescent Psychiatry of the University Medical Centre Utrecht, the Netherlands were reassessed for adult schizotypal symptoms. Severity of behavioral symptoms in childhood and adolescence using Teacher Report Form (TRF; Verhulst et al. 1997) and adult schizotypal symptoms using Schizotypal Personality Questionnaire-Revised (Raine in Schizophrenia Bulletin 17:555-564, 1991) were examined by Spearman's bivariate correlations. Multiple regression analyses were performed to determine the combined predictive value of significant TRF subscales for schizotypal symptomatology. Moderation was tested by adding the interactions of gender with TRF subscales to the models. Disregarding gender, correlational analyses revealed that TRF Total problems, in specific thought problems, social problems, and attentional problems were associated with disorganized schizotypal symptoms in adult life. TRF thought problems was also associated with future positive schizotypal symptoms. When gender was taken into account, for boys only thought problems was associated with adult positive schizotypal symptoms, whereas for girls externalizing problems, specifically attentional and aggressive problems, were associated with the higher levels of adult disorganized schizotypal symptoms. Moderated regression analyses provided trend significant evidence confirming that in girls externalizing problems were positively associated with general and disorganized schizotypal symptoms. When using teachers as informants, it was found that juvenile behavioral abnormalities were differentially associated with type of adult schizotypal symptoms, with these associations being further modified by gender.

    Full Text Available Introduction: Given the disruptive effects of personality disorders on personal and family life, it is essential to recognize their predisposing factors to understand them more accurately, and identify their preventive measures treatment facilitators. Therefore, the present study aimed to examine the relationship of severe personality disorders with behavioral activation and inhibition systems in patients with paranoid, borderline and schizotypal personality disorders. Methods: The present descriptive-correlational study recruited patients with paranoid, borderline and schizotypal personality disorders presenting to psychiatry clinics in Ardabil using convenient sampling method. A total of 30 paranoid patients, 30 borderline patients and 20 schizotypal patients were selected by a psychiatrist through psychiatric examination, clinical interview and completing Millon Clinical Multiaxial Inventory (MCMI-III. The following instruments were used: MCMI- III and behavioral activation-inhibition system scale (BIS-BAS. The data were analyzed with Pearson’s correlation coefficient and stepwise regression. Results: BIS and BAS systems were both significant for predicting borderline and paranoid personality disorders, but only BIS was significant for predicting schizotypal personality disorder. Conclusion: These findings can help experts to have a better and more accurate understanding of personality disorders and use proper methods to predict the probability of these disorders and develop treatments.

  11. Social Media and Experiential Ambivalence

    Full Text Available At once fearful and dependent, hopeful and distrustful, our contemporary relationship with technology is highly ambivalent. Using experiential accounts from an ongoing Facebook-based qualitative study (N = 231, I both diagnose and articulate this ambivalence. I argue that technological ambivalence is rooted primarily in the deeply embedded moral prescription to lead a meaningful life, and a related uncertainty about the role of new technologies in the accomplishment of this task. On the one hand, technology offers the potential to augment or even enhance personal and public life. On the other hand, technology looms with the potential to supplant or replace real experience. I examine these polemic potentialities in the context of personal experiences, interpersonal relationships, and political activism. I conclude by arguing that the pervasive integration and non-optionality of technical systems amplifies utopian hopes, dystopian fears, and ambivalent concerns in the contemporary era.

    The main objective of the study was to validate the Schizotypal Personality Questionnaire-Brief (SPQ-B) in a sample of non-clinical adolescents. In addition, the schizotypal personality structure and differences in the dimensions of schizotypy according to gender and age are analyzed. The sample comprises 1683 students, 818 males (48.6%), with a mean age of 15.9 years (SD=1.2). The results showed that the SPQ-B had adequate psychometric properties. Internal consistency of the subscales and total score ranged from 0.61 to 0.81. Confirmatory factor analyses indicated that the three-factor model (positive, negative, and disorganized) and the four-factor model (positive, paranoid, negative, and disorganized) fit reasonably well in comparison to the remaining models. With regard to gender and age, statistically significant differences were found due to age but not to gender. In line with previous literature, the results confirmed the multi-factor structure of the schizotypal personality in non-clinical adolescent populations. Future studies could use the SPQ-B as a screening self-report of rapid and efficient application for the detection of adolescents vulnerable to the development of schizophrenia-spectrum disorders in the general population, in genetically high-risk samples and in clinical studies.

    Numerous authors have theorized that defense mechanisms play a role in personality disorders. We reviewed theoretical writings and empirical studies about defenses in schizotypal, borderline, antisocial, and narcissistic personality disorders, developing hypotheses about these differential relationships. We then examined these hypotheses using dynamic interview data rated for defenses in a study of participants (n = 107) diagnosed with these four personality disorder types. Overall, the prevalence of immature defenses was substantial, and all four disorders fit within the broad borderline personality organization construct. Defenses predicted the most variance in borderline and the least variance in schizotypal personality disorder, suggesting that dynamic factors played the largest role in borderline and the least in schizotypal personality. Central to borderline personality were strong associations with major image-distorting defenses, primarily splitting of self and other's images, and the hysterical level defenses, dissociation and repression. Narcissistic and antisocial personality disorders shared minor image-distorting defenses, such as omnipotence or devaluation, while narcissistic also used splitting of self-images and antisocial used disavowal defenses like denial. Overall, differential relationships between specific defenses and personality disorder types were largely consistent with the literature, and consistent with the importance that the treatment literature ascribes to working with defenses.

    The Schizotypal Personality Questionnaire-Brief (SPQ-B) is a commonly-used tool for measuring schizotypal personality traits and due to its wide application, its cross-cultural validity is of interest. Previous studies suggest that the SPQ-B either has a three- or four-factor structure, but the majority of studies have been conducted in Western contexts and little is known about the psychometric properties of the scale in other populations. In this study factorial invariance testing across three cultural contexts-Australia, China and Chile was conducted. In total, 729 young adults (Mean age = 23.99 years, SD = 9.87 years) participated. Invariance testing did not support the four-factor model across three countries. Confirmatory Factor Analyses revealed that neither the four- nor three-factor model had strong fit in any of the settings. However, in comparison with other competing models, the four-factor model showed the best for the Australian sample, while the three-factor model was the most reasonable for both Chinese and Chilean samples. The reliability of the SPQ-B scores, estimated with Omega, ranged from 0.86 to 0.91. These findings suggest that the SPQ-B factors are not consistent across different cultural groups. We suggest that these differences could be attributed to potential confounding cultural and translation issues. Copyright © 2017 Elsevier B.V. All rights reserved.

  15. Schizotypal perceptual aberrations of time: correlation between score, behavior and brain activity.

    Directory of Open Access Journals (Sweden)

    Shahar Arzy

    Full Text Available A fundamental trait of the human self is its continuum experience of space and time. Perceptual aberrations of this spatial and temporal continuity is a major characteristic of schizophrenia spectrum disturbances--including schizophrenia, schizotypal personality disorder and schizotypy. We have previously found the classical Perceptual Aberration Scale (PAS scores, related to body and space, to be positively correlated with both behavior and temporo-parietal activation in healthy participants performing a task involving self-projection in space. However, not much is known about the relationship between temporal perceptual aberration, behavior and brain activity. To this aim, we composed a temporal Perceptual Aberration Scale (tPAS similar to the traditional PAS. Testing on 170 participants suggested similar performance for PAS and tPAS. We then correlated tPAS and PAS scores to participants' performance and neural activity in a task of self-projection in time. tPAS scores correlated positively with reaction times across task conditions, as did PAS scores. Evoked potential mapping and electrical neuroimaging showed self-projection in time to recruit a network of brain regions at the left anterior temporal cortex, right temporo-parietal junction, and occipito-temporal cortex, and duration of activation in this network positively correlated with tPAS and PAS scores. These data demonstrate that schizotypal perceptual aberrations of both time and space, as reflected by tPAS and PAS scores, are positively correlated with performance and brain activation during self-projection in time in healthy individuals along the schizophrenia spectrum.

    The explicit and implicit memory of nonclinical individuals with schizotypal traits was investigated using event-related potentials. Explicit and implicit memory was measured with continuous recognition and categorization tasks, respectively. On the recognition task, the control group demonstrated a greater old/new effect in response to the old than to the new words during the 250-750 ms post-stimulus period, whereas schizotypal trait group did not exhibit an old/new effect during the 550-650 ms period. The control group demonstrated faster response times to the old than to the new words, whereas the schizotypal group demonstrated longer response times to the old than to the new words. On the categorization task, both groups showed old/new effects during the 250-550 ms after stimulus onset and responded more rapidly and with fewer errors to the old than to the new words. These results suggest that individuals with schizotypal traits have impaired explicit but preserved implicit memory. Copyright © 2011 Elsevier B.V. All rights reserved.

    The psychological benefit of gratitude has been well demonstrated in previous studies. However, when we examined these studies closely, we found that the moderators were rarely investigated, suggesting that further work is needed to explore the boundaries of gratitude In this regard, the authors have proposed that ambivalence over emotional expression might be a potential moderator that would inhibit the beneficial effect of gratitude on well-being. Two studies were conducted to examine our hypothesis. Study 1 consisted of 353 Taiwanese college students who completed the Gratitude Questionnaire-Taiwan version (GQ-T), Ambivalence over Emotional Expression Questionnaire (AEQ), and one question about subjective happiness. We found that ambivalence over emotional expression significantly moderated the effect of gratitude on happiness. To validate our findings in Study 1, 233 Taiwanese college students were recruited for Study 2, and they completed the GQ-T, AEQ, subjective happiness short-form UCLA loneliness scale, as well as the Center for Epidemiological Studies Depression Scale (CES-D). Both studies demonstrated that ambivalence over emotional expression moderated the relationship between gratitude and well-being indexes. Simply stated, the authors found that across the two independent samples, among students who are high in ambivalence over emotional expression, the beneficial effect of gratitude on subjective happiness was inhibited. However, the moderating pattern for loneliness and depression was contrary to our expectations, indicating that high ambivalence over emotional expression does not inhibit gratitude. Possible explanations and implications for social relationships and emotional expression are discussed.

    Full Text Available The rising interest in temporally coherent brain networks during baseline adult cerebral activity finds convergent evidence for an identifiable set of resting state networks (RSNs. To date, little is know concerning the earlier developmental stages of functional connectivity in RSNs. This study’s main objective is to characterize the RSNs in a sample of adolescents. We further examine our data from a developmental psychopathology perspective of psychosis-proneness, by testing the hypothesis that early schizotypal symptoms are linked to disconnection in RSNs. In this perspective, this study examines the expression of adolescent schizotypal traits and their potential associations to dysfunctional RSNs. Thirty-nine adolescents aged between 12 and 20 years old underwent an eight minute fMRI “resting state” session. In order to explore schizotypal trait manifestations, the entire population was assessed by the Schizotypal Personality Questionnaire (SPQ. After conventional processing of the fMRI data, we applied group-level independent component analysis (ICA. Twenty ICA maps and associated time-courses were obtained, among which there were resting state networks (RSNs that are consistent with findings in the literature. We applied a regression analysis at group level between the energy of RSN-associated time courses in different temporal frequency bins and the clinical measures (3 in total. Our results highlight the engagement of six relevant RSNs; 1 a default-mode network; 2 a dorso-lateral attention network; 3 a visual network; 4 an auditory network; 5 a sensory motor network; 6 a self-referential network. The regression analysis reveals a statistically significant correlation between the clinical measures and some of the RSNs, specifically the visual and the auditory network. In particular, a positive correlation is obtained for the visual network in the low frequency range (0.05 Hz with SPQ measures, while the auditory network correlates

    Emotional facial expressions are indispensable communicative tools, and social interactions involving facial expressions are impaired in some psychiatric disorders. Recent studies revealed that the perception of dynamic facial expressions was exaggerated in normal participants, and this exaggerated perception is weakened in autism spectrum disorder (ASD). Based on the notion that ASD and schizophrenia spectrum disorder are at two extremes of the continuum with respect to social impairment, we hypothesized that schizophrenic characteristics would strengthen the exaggerated perception of dynamic facial expressions. To test this hypothesis, we investigated the relationship between the perception of facial expressions and schizotypal traits in a normal population. We presented dynamic and static facial expressions, and asked participants to change an emotional face display to match the perceived final image. The presence of schizotypal traits was positively correlated with the degree of exaggeration for dynamic, as well as static, facial expressions. Among its subscales, the paranoia trait was positively correlated with the exaggerated perception of facial expressions. These results suggest that schizotypal traits, specifically the tendency to over-attribute mental states to others, exaggerate the perception of emotional facial expressions.

    Childhood trauma has been shown to be a robust risk factor for mental disorders, and may exacerbate schizotypal traits or contribute to autistic trait severity. However, little is known whether childhood trauma confounds the overlap between schizotypal traits and autistic traits. This study examined whether childhood trauma acts as a confounding variable in the overlap between autistic and schizotypal traits in a large non-clinical adult sample. A total of 2469 participants completed the Autism Spectrum Quotient (AQ), the Schizotypal Personality Questionnaire (SPQ), and the Childhood Trauma Questionnaire-Short Form. Correlation analysis showed that the majority of associations between AQ variables and SPQ variables were significant (p autistic and schizotypal traits could not be explained by shared variance in terms of exposure to childhood trauma. The findings point to important overlaps in the conceptualization of ASD and SSD, independent of childhood trauma. Copyright © 2017 Elsevier B.V. All rights reserved.

    In this study, we examined intimate partner violence (IPV), cold violence, and controlling behaviors in male same-sex relationships in China, with a focus on the characteristics of IPV and controlling behaviors, and their relationships with ambivalent sexism. IPV was categorized as psychological aggression, physical injury, physical assault, and sexual coercion and was measured using the revised Conflict Tactics Scales (CTS2), an eight-item scale measuring cold violence that was designed specifically for this study. Controlling behaviors were measured using a 34-item scale that was designed for this study, and sexist attitudes toward women and men were assessed using the short forms of the Ambivalent Sexism Inventory (ASI) and the Ambivalence toward Men Inventory (AMI), respectively. Participants ( N = 272) reported instances of perpetration of or victimization by IPV and controlling behaviors within the past 6 months and indicated ambivalent sexism (hostile attitude toward men and women and benevolent attitude toward men and women [HM, HS, BM, and BS, respectively]). Almost 47.1% of the participants reported an experience of IPV, and the prevalence of cold violence and controlling behaviors was found to be 65.1% and 80.5%, respectively. Psychological aggression was the most common, followed sequentially by sexual coercion, physical assault, and injury in present study. We found a strong association between perpetration and victimization and that different forms of violence tend to co-occur in both IPV and controlling behaviors. As predicted, ambivalent sexism was positively correlated with IPV and controlling behaviors, specifically HS and HM. The results indicated the high prevalence of IPV and controlling behaviors among male same-sex relationships, and sexism contributing to this high prevalence.

    Previous functional neuroimaging studies have reported that patients with schizophrenia show reduced prefrontal activation during cognitive tasks whereas patients with schizotypal personality disorder (SPD) show preserved or even increased right prefrontal activation, compared to healthy controls; on the other hand, reduced hemispheric laterality is considered to be common to these two disorders. The aim of this study was to examine the possible association between schizotypal traits at a nonclinical level and prefrontal activation patterns during a letter version of the verbal fluency task (VFT). We examined the relationships of schizotypal traits as measured by the Schizotypal Personality Questionnaire (SPQ) in a nonclinical female population with prefrontal activation patterns during the VFT, using near-infrared spectroscopy. Twenty-seven healthy participants were divided into high (n = 14) and low (n = 13) SPQ groups by the median split of the total SPQ score. Compared to the low SPQ group, the high SPQ group showed significantly larger right prefrontal activation during the performance of the VFT, leading to more bilateral activation. Our results suggest that schizotypal traits at a nonclinical level may be related to relative right prefrontal laterality with overall prefrontal activation being preserved, consistent with previous findings obtained by studies of patients with SPD. 2008 S.

    When participants observed a rubber hand being touched, their sense of touch was activated (rubber hand illusion: RHI). While this illusion might be caused by multi-modal integration, it may also be related to empathic function, which enables us to simulate the observed information. We examined individual differences in the RHI, including empathic and schizotypal personality traits, as previous research had suggested that schizophrenic patients would be more subject to the RHI. The results indicated that people who experience a stronger RHI might have stronger empathic and schizotypal personalites simultaneously. We discussed these relationships in terms of self-other representations. Copyright © 2011 Elsevier Inc. All rights reserved.

    Americans' conflicted attitudes toward immigrants and immigration has stymied immigration reform for decades. In this article, we explore the nuanced nature of stereotypes about immigrants and how they relate to ambivalent attitudes toward immigrant groups and the disparate array of immigration policies that affect them. Using item response theory and multiple regression analysis, we identified and related stereotypes of different immigrant groups to group-based and policy attitudes. Results demonstrate that ambivalent stereotypes mapped onto ambivalent group-based and immigration policy attitudes. Specifically, stereotypes that portray groups in positive or sympathetic ways predicted positive attitudes toward the group and more supportive attitudes toward policies that facilitate their immigration to the United States. Conversely, negative qualities predicted negative attitudes toward the same group and support for policies that prevent the group from immigrating. Results are discussed in light of current theory related to stereotype content, complementarity of stereotypes, and broader implications for immigration attitudes and policy.

    Ambivalence toward alcohol often develops when hazardous drinkers try to quit or to control their drinking. The purpose of this study was to investigate the differences between hazardous drinkers with and without ambivalence toward alcohol in terms of their visual attention to alcohol-related pictures over time using an eye-tracker. The study included 20 hazardous drinkers with ambivalence and 21 hazardous drinkers without ambivalence. The eye movements of the participants were monitored while the participants conducted a free-viewing task in which 20 pairs of alcohol-related pictures and matched control pictures were presented. The results showed that the hazardous drinkers with ambivalence were more attentive to the alcohol-related pictures at first and were more attentive to the control pictures toward the end of the task. On the other hand, the hazardous drinkers without ambivalence were more attentive to the alcohol-related pictures from beginning to end. The findings of this study indicated that ambivalence toward alcohol resulted in the inclination to approach and then avoid alcohol in a consecutive sequence. The present results could be helpful in distinguishing hazardous drinkers who may have ambivalence toward alcohol and identifying the pattern of ambivalence more concretely. Additionally, further studies need to consider the time that is important to measure ambivalence toward alcohol. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Moral decisions and social relationships are often characterized by strong feelings of ambivalence which can be a catalyst for emotional distress and several health-related problems. The anterior cingulate cortex (ACC) has been identified as a key brain region in monitoring conflicting information, but the neurobiological substrates of ambivalence processing are still widely unknown. We have conducted two randomized, double-blind, placebo-controlled, functional magnetic resonance imaging experiments involving 70 healthy male volunteers to investigate the effects of the neuropeptide oxytocin (OXT) on neural and behavioral correlates of ambivalence. We chose moral decision-making and the imagery of partner infidelity as examples to probe volitional and emotional ambivalence. In both experiments, intranasal OXT diminished neural responses in the ACC to ambivalence. Under OXT, moral dilemma vignettes also elicited a reduced activation in the orbitofrontal cortex, and the imagery of partner infidelity was rated as less arousing. Interestingly, the OXT-induced differential activation in the ACC predicted the magnitude of arousal reduction. Taken together, our findings reveal an unprecedented role of OXT in causing a domain-general decrease of neural responses to ambivalence. By alleviating emotional distress, OXT may qualify as a treatment option for psychiatric disorders with heightened ambivalence sensitivity such as schizophrenia or obsessive-compulsive disorder. © The Author (2014).

  8. [Structuralistic and meta-psychological approaches to ambivalence in schizophrenia].

    2003-01-01

    The word "ambivalence" generally signifies a psychic state in which a subject holds a contradictory or conflicted attitude towards an object. The literal meaning of the word is that two valences occur simultaneously, and this connotes the epistemological and ethical problem of where and how the valences arise. The concept of ambivalence implies that the relationship between the subject and the world is ambivalent, that the subject has free will in the alternative evaluation, and that the meanings of the two valences derive from the meta-level outside the world. These reflections lead us to the supposition that ambivalence is closely associated with the function of language. The ambivalent attitude of the subject divides the significance of the object; the appearance of the given ambivalent meanings is the moment of the subject's choice. This phenomenon of division, choice, and given meanings is more than analogous to F. de Saussure's conception of language in terms of sign, différenciation, and l'arbitraire de langue. A view of ambivalence as a fundamental phenomenon concerning subject, world, and language affords insight specifically into ambivalence in schizophrenia. For people with schizophrenia, ambivalent conflict often takes the form of a dichotomy between "good and bad". The more severe the ambivalent symptom, the more similar it seems to a philosophical question about the nature of existence in the world. When schizophrenic people raise philosophical questions directly such as "Is my existence good or bad?" or "To be or not to be?", they seek approval for their existence, assaying to live with "good" intentions. Unfortunately they come to be blamed for harbouring "bad" intentions. When they have an interrogative attitude even to everyday matters, they cannot resolve such questions as "Is the red cup good or bad?", or "Is the green cup good or bad?", and hence "Which cup should I use?". If the projection of the self into the world is essentially the choice

    Studies of the five-factor model of personality in schizotypal personality disorder (SPD) have produced inconsistent results, particularly with respect to openness. In the present study, the NEO-FFI was used to measure five-factor personality dimensions in 28 community volunteers with SPD and 24 psychiatrically healthy individuals. Standard multivariate statistical analyses were used to evaluate personality differences as a function of diagnosis and gender. Individuals with SPD had significan...

    This study assessed the moderating effects of attitude ambivalence on the relationship between social norms, attitudes, and behavioral intentions to use tobacco. It was predicted that people would use social norms to reduce attitude ambivalence, and that reduced ambivalence would lead to changes in attitudes and behavioral intentions. To test this hypothesis, participants (N =152) were exposed to persuasive communications designed to influence attitude ambivalence and perceived social norms regarding tobacco use. Analysis indicated that providing a social norm antagonistic to tobacco use significantly reduced ambivalence among participants reading the ambivalence message (p changes in tobacco attitudes from pre- to postpersuasive communications demonstrated a significant decrease in tobacco attitudes only for participants reading the ambivalence message who were provided with the antitobacco use norm (p changes in attitudes toward tobacco. These results point to the important role of social norms in mediating the effects of attitude ambivalence on subsequent behavior in preventative programs targeting tobacco use. PMID:26460476

    Full Text Available Markedly raised incidence rates of schizophrenia and other psychotic disorders have been observed in several migrant and ethnic minority groups. To contribute to a better understanding of the elevated risk for psychotic disorders that is conferred by migration status, the present study examined effects associated with migration risk status on schizotypal personality traits, which are thought to reflect an underlying vulnerability to psychotic disorder. Effects of migration status were also compared to effects associated with a family history of psychopathology, which represents a robust nonspecific risk factor. We assessed schizotypal traits, using the Schizotypal Personality Questionnaire (SPQ, in a community-based sample of 62 Moroccan migrants and 41 Dutch nonmigrants, who were classified by the presence or absence of a family history of psychopathology. Overall, Moroccan migrants obtained higher SPQ scores than Dutch nonmigrants. However, migrants who had been classified as having a familial load of psychopathology displayed higher SPQ scores than migrants without such a family history, who in turn did not differ from Dutch nonmigrants. Furthermore, migrants with a familial load, relative to migrants without such a family history, reported higher levels of substance use and feelings of anxiety or depression, and perceived more often ethnic discrimination, which closely paralleled their SPQ scores. These findings indicate that primarily those migrants who are both intrinsically vulnerable and chronically exposed to social adversity, particularly ethnic discrimination, are at elevated risk for psychotic and other disorders. The results add to the evidence that migration status and perceived discrimination are associated with mental health.

  14. Poor nutrition at age 3 and schizotypal personality at age 23: the mediating role of age 11 cognitive functioning.

    2012-08-01

    Poor prenatal nutrition has been associated with schizophrenia spectrum disorders in the Netherlands and China, and it has been suggested that perinatal and postnatal nutritional factors lead to the development of schizophrenia and the exhibition of schizotypal traits later in life. There appears to be no prior research on the existence of possible factors that may mediate the relationship between malnutrition and schizophrenia spectrum disorders or whether this association is a direct one. The authors tested the hypothesis that low IQ mediates the relationship between early childhood malnutrition and adult schizotypal personality. Participants were drawn from a birth cohort of 1,795 boys and girls who were followed prospectively. Objective indicators of malnutrition (anemia and stunting) were assessed at age 3. Verbal and performance intelligence were assessed at age 11, and schizotypal personality was assessed at age 23. Both stunting and anemia at age 3 were associated with low IQ at age 11. Low performance IQ at age 11 was associated with increased interpersonal and disorganized features of schizotypal personality at age 23. Poor performance IQ was found to mediate the relationship between poor nutrition at age 3 and interpersonal and disorganized features of schizotypy at age 23. Findings in female participants were replicated in male participants. Given that poor nutrition is an alterable risk factor, these findings suggest that nutritional enhancements may improve brain functioning and possibly reduce some features of schizotypal personality disorder.

    Full Text Available Manifestations of sexism are under the constant influence of social changes and changes in gender relations. This paper presents modern forms of sexism, with an emphasis on the ambivalent sexism theory (Glick and Fiske, 1996. Ambivalent sexism theory addresses sexism not only on societal but also on interpersonal and personal level. In addition, this article provides a comprehensive review of the empirical findings in the field of benevolent and hostile sexism and their effect on close relations, sexual violence, beauty ideals and practices, women’s self-esteem, and their career decisions and aspirations. Finally, I place ambivalent sexism theory into the broader societal and psychological context and discuss the possibilities of surmounting current sexist ideologies and practices.

  16. High estradiol levels improve false memory rates and meta-memory in highly schizotypal women.

    Overconfidence in false memories is often found in patients with schizophrenia and healthy participants with high levels of schizotypy, indicating an impairment of meta-cognition within the memory domain. In general, cognitive control is suggested to be modulated by natural fluctuations in oestrogen. However, whether oestrogen exerts beneficial effects on meta-memory has not yet been investigated. The present study sought to provide evidence that high levels of schizotypy are associated with increased false memory rates and overconfidence in false memories, and that these processes may be modulated by natural differences in estradiol levels. Using the Deese-Roediger-McDermott paradigm, it was found that highly schizotypal participants with high estradiol produced significantly fewer false memories than those with low estradiol. No such difference was found within the low schizotypy participants. Highly schizotypal participants with high estradiol were also less confident in their false memories than those with low estradiol; low schizotypy participants with high estradiol were more confident. However, these differences only approached significance. These findings suggest that the beneficial effect of estradiol on memory and meta-memory observed in healthy participants is specific to highly schizotypal individuals and might be related to individual differences in baseline dopaminergic activity.

    The main objective of the study was to explore the factorial structure of the French version of the Schizotypal Personality Questionnaire-Brief (SPQ-B) in a Likert format, in a representative sample of the general population. In addition, differences in the dimensional scores of schizotypy according to gender and age were analyzed. As the study in the general population of schizotypal traits and its determinants has been recently proposed as a way toward the understanding of aetiology and pathophysiology of schizophrenia, consistent self-report tools are crucial to measure psychometric schizotypy. A shorter version of the widely used Schizotypal Personality Questionnaire (SPQ-Brief) has been extensively investigated in different countries, particularly in samples of students or clinical adolescents, and more recently, a few studies used a Likert-type scale format which allows partial endorsement of items and reduces the risk of defensive answers. A sample of 233 subjects representative of the adult population from an urban area near Paris (Créteil) was recruited using the "itinerary method". They completed the French version of the SPQ-B with a 5-point Likert-type response format (1=completely disagree; 5=completely agree). We examined the dimensional structure of the French version of the SPQ-B with a Principal Components Analysis (PCA) followed by a promax rotation. Factor selection was based on Eigenvalues over 1.0 (Kaiser's criterion), Cattell's Scree-plot test, and interpretability of the factors. Items with loadings greater than 0.4 were retained for each dimension. The internal consistency estimate of the dimensions was calculated with Cronbach's α. In order to study the influence of age and gender, we carried out a simple linear regression with the subscales as dependent variables. Our sample was composed of 131 women (mean age=52.5±18.2 years) and 102 men (mean age=53±18.1 years). SPQ-B Likert total scores ranged from 22 to 84 points (mean=43.6

    Full Text Available The present study examined the mediating effects of ambivalent sexism (hostile and benevolent in the relationship between sex role orientation (masculinity and femininity and gender stereotypes (dominance and assertiveness in college students. The variables were measured using the Bem Sex Role Inventory (BSRI, the Ambivalent Sexism Inventory (ASI, and the Attitudes toward Gender Stereotypes in Romantic Relationships Scale (AGSRRS. These inventories were administered to 250 undergraduate students at Istanbul University in Istanbul and Suleyman Demirel University in Isparta, Turkey. Results indicate that benevolent sexism mediates the relationship between hostile sexism and male dominance. Benevolent sexism also mediates femininity and male dominance, as well as femininity and male assertiveness. Hostile sexism was mediated only between the masculine personality trait and benevolent sexism. The present findings expand the literature on sex role orientation by revealing evidence that masculine and feminine individuals experience ambivalent sexism distinctively. The results are discussed in terms of the assumptions of sex role orientation, ambivalent sexism, and gender stereotypes.

    This study investigates the extent to which the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) profiles of 52 individuals making up a psychometrically identified schizotypes (SZT) sample could be successfully discriminated from the protocols of 52 individuals in a matched comparison (MC) sample. Replication analyses were performed with an additional 53 pairs of SZT and MC participants. Results showed significant differences in mean T-score values between these 2 groups across a variety of MMPI-2-RF scales. Results from discriminant function analyses indicate that schizotypy can be predicted effectively using 4 MMPI-2-RF scales and that this method of classification held up on replication. Additional results demonstrated that these MMPI-2-RF scales nominally outperformed MMPI-2 scales suggested by previous research as being indicative of schizophrenia liability. Directions for future research with the MMPI-2-RF are suggested.

  20. Network Ambivalence

    Full Text Available The language of networks now describes everything from the Internet to the economy to terrorist organizations. In distinction to a common view of networks as a universal, originary, or necessary form that promises to explain everything from neural structures to online traffic, this essay emphasizes the contingency of the network imaginary. Network form, in its role as our current cultural dominant, makes scarcely imaginable the possibility of an alternative or an outside uninflected by networks. If so many things and relationships are figured as networks, however, then what is not a network? If a network points towards particular logics and qualities of relation in our historical present, what others might we envision in the future? In  many ways, these questions are unanswerable from within the contemporary moment. Instead of seeking an avant-garde approach (to move beyond networks or opting out of networks (in some cases, to recover elements of pre-networked existence, this essay proposes a third orientation: one of ambivalence that operates as a mode of extreme presence. I propose the concept of "network aesthetics," which can be tracked across artistic media and cultural forms, as a model, style, and pedagogy for approaching interconnection in the twenty-first century. The following essay is excerpted from Network Ambivalence (Forthcoming from University of Chicago Press.

    The study of non-clinical individuals with schizotypal traits has been considered to provide a promising endophenotypic approach to understanding schizophrenia, because schizophrenia is highly heterogeneous, and a number of confounding factors may affect neuropsychological performance. Here, we investigated whether deficits in explicit verbal memory in individuals with schizotypal traits are associated with abnormalities in the local and inter-regional synchrony of brain activity. Memory deficits have been recognized as a core problem in schizophrenia, and previous studies have consistently shown explicit verbal memory impairment in schizophrenic patients. However, the mechanism of this impairment has not been fully revealed. Seventeen individuals with schizotypal traits and 17 age-matched, normal controls participated. Multichannel event-related electroencephalograms (EEGs) were recorded while the subjects performed a continuous recognition task. Event-related spectral perturbations (ERSPs) and inter-regional theta-band phase locking values (TPLVs) were investigated to determine the differences in local and global neural synchrony between the two subject groups. Additionally, the connection patterns of the TPLVs were quantitatively analyzed using graph theory measures. An old/new effect was found in the induced theta-band ERSP in both groups. However, the difference between the old and new was larger in normal controls than in schizotypal trait group. The tendency of elevated old/new effect in normal controls was observed in anterior-posterior theta-band phase synchrony as well. Our results suggest that explicit memory deficits observed in schizophrenia patients can also be found in non-clinical individuals with psychometrically defined schizotypal traits.

    Full Text Available Recent decades have witnessed online social media being a big-data window for testifying conventional social theories quantitatively and exploring much detailed human behavioral patterns. In this paper, by tracing the emoticon use in Weibo, a group of hidden "ambivalent users" are disclosed for frequently posting ambivalent tweets containing both positive and negative emotions. Further investigation reveals that this ambivalent expression could be a novel indicator of many unusual social behaviors. For instance, ambivalent users with the female as the majority like to make a sound in midnights and at weekends. They mention their close friends frequently in ambivalent tweets, which attract more replies and serve as a more private communication way. Ambivalent users also respond differently to public affairs from others and demonstrate more interests in entertainment and sports events. Moreover, the sentiment shift in ambivalent tweets is more evident than usual and exhibits a clear "negative to positive" pattern. The above observations, though being promiscuous seemingly, actually point to the self-regulation of negative mood in Weibo, which could find its basis from the traditional emotion management theories in sociology but makes an important extension to the online environment in this study. Finally, as an interesting corollary, ambivalent users are found connected with compulsive buyers and turn out to be perfect targets for online marketing.

    The primary aim of the current study was to investigate different aspects of theory of mind (ToM), including social-cognitive (ToM-reasoning) and social-perceptual (ToM-decoding) in obsessive-compulsive disorder (OCD). We also aimed to investigate the relationship between ToM, neurocognition and a number of clinical variables including overvalued ideas, schizotypal personality traits, level of insight, and disease severity. Thirty-four patients who have been diagnosed with OCD according to DSM-IV and 30 healthy controls were included in the study. All participants were given a neuropsychological battery including tasks measuring ToM-reasoning, ToM-decoding and other neurocognitive functions. Schizotypal Personality Questionnaire (SPQ), Yale Brown Obsession and Compulsion Scale (YBOC-S) and Overvalued Ideas Scale (OVIS) were also administered to the participants. Patients with OCD showed significant deficits in both aspects of ToM. ToM performances of patients showed a significant positive correlation with neurocognitive functions. When controlled for general cognition factor, patient-control difference for ToM-reasoning (F = 3,917; p = 0,05), but not ToM-decoding, remained statistically significant. ToM-reasoning impairment of patients was significantly related to the severity of OCD symptoms and poor insight (p = 0,026 and p = 0,045, respectively). On the other hand, general cognitive factor (β = 0,778; t = 3,146; p = 0,04) was found to be the only significant predictor of ToM-reasoning in OCD patients in the multiple linear regression model. OCD is associated with ToM impairment, which is related to schizotypal traits, disease severity and poor insight, yet neurocognitive deficits also significantly contribute to this finding. However, ToM-reasoning impairment could be considered as a relatively distinct feature of OCD, which is partly separate from general cognitive deficits. Copyright © 2018. Published by Elsevier Inc.

  5. Ambiguity, Ambivalence and Extravagance in The Hunger Games

    2014-01-01

    I argue that Katniss Everdeen from The Hunger Games is an emblem of what Julia Kristeva calls the “extravagant girl” who wants to have it all and to be the best at everything. Katniss has an ambiguous gender identity, both masculine and feminine, paternal and maternal. And she has ambivalent desires. I conclude that this ambiguity and ambivalence open up new possibilities for girls and initiate an aesthetics of ambiguity.

    This study relates to the schizotypal personality disorder (SPD) proposal of the upcoming fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) by investigating the construct validity of SPD as defined by DSM-IV in a large sample of patients from the Norwegian Network of Personality-Focused Treatment Programs (N = 2619), assessed by structured diagnostic interviews and the Longitudinal, Expert All Data standard. We investigated factor structure and psychometric properties of the SPD criteria, as well as co-occurrence patterns between SPD and other PDs. Thirty-six patients were diagnosed with SPD and 513 patients (21%) endorsed at least 2 schizotypal criteria. We found that 2 factors were specific for SPD, a cognitive-perceptual factor (ideas of reference, magical thinking, and unusual perceptual experiences) and an oddness factor (odd thinking and speech, constricted affect, and odd appearance or behavior). The criteria belonging to these factors had appropriate psychometric properties. The criteria of the cognitive-perceptual factor were more strongly associated with borderline personality disorder (PD) than with the other PDs. We did not find support for a consistent factor that reflected interpersonal problems. The criteria that used to be part of this factor (suspiciousness, lack of friends or confidants, and excessive social anxiety) performed poorly as specific SPD criteria. SPD was more strongly associated with antisocial PD and paranoid PD than with the other PDs. We suggest that ideas of reference should be included explicitly under the schizotypal facet of cognitive dysregulation in DSM-5, with less emphasis on the social phobic aspects of this feature. Furthermore, there should be more emphasis on the cognitive aspects of suspiciousness in SPD, and it should be considered to split up the affectivity criterion into constricted affect and inappropriate affect, with the latter type of affect being the expression of problems with

    Fertility intentions often can predict contraceptive demand and fertility outcomes. Little is known about women reporting ambivalent fertility intentions, who are usually classified as having an unmet need for contraception. This study's objectives were to determine 1) which fertility intention group ambivalent women more closely resemble and 2) whether ambivalent women seem to have an unmet contraceptive need. We analyzed longitudinal data from 1,018 married Balinese women aged 15 to 45, of whom 33% desired more children, 52% wanted no more, and 14% were ambivalent. Ambivalent women were compared with those with definitive intentions using bivariate analyses. Regression analysis was used to determine the predictors of birth avoidance. Although ambivalent women were significantly older, and had less education and more children than women who wanted more children, ambivalent women were more similar in their contraceptive use to those who wanted more children than those who wanted no more. However, in terms of birth outcomes, ambivalent women resembled more the women who intended to avoid childbearing: After 4 years, 33% of ambivalent women had another birth compared with 29% of women who wanted no more and 57% of women who desired more children. Contraceptive use at baseline did not predict ambivalent women's fertility outcomes, unlike the other groups. Despite their relatively low rates of contraceptive use at baseline, ambivalent women generally avoided giving birth during the study period. This suggests that ambivalent women may not have a high unmet need for family planning. Copyright © 2011 Jacobs Institute of Women's Health. Published by Elsevier Inc. All rights reserved.

    Considerable overlap in symptoms between patients with borderline personality disorder (BPD) and schizotypal personality disorder (STPD) complicates personality diagnostics. Yet very little is known about the level of psychodynamic functioning of both personality disorders. Psychodynamic assessment procedures may specify personality characteristics relevant for differential diagnosis and treatment planning. In this cross-sectional study we explored the differences and similarities in level of personality functioning and psychodynamic features of patients with severe BPD or STPD. In total, 25 patients with BPD and 13 patients with STPD were compared regarding their level of personality functioning (General Assessment of Personality Disorder), current quasipsychotic features (Schizotypal Personality Questionnaire), and psychodynamic functioning [Developmental Profile (DP) interview and Developmental Profile Inventory (DPI) questionnaire]. Both groups of patients showed equally severe impairments in the level of personality functioning and the presence of current quasipsychotic features. As assessed by the DP interview, significant differential psychodynamic patterns were found on the primitive levels of functioning. Moreover, subjects with BPD had significantly higher scores on the adaptive developmental levels. However, the self-questionnaire DPI was not able to elucidate all of these differences. In conclusion, our study found significant differences in psychodynamic functioning between patients with BPD and STPD as assessed with the DP interview. In complicated diagnostic cases, personality assessment by psychodynamic interviewing can enhance subtle but essential differentiation between BPD and STPD.

    To date, little research has examined the impact of attitudinal ambivalence on attitude-congruent selective exposure. Past research would suggest that strong/univalent rather than weak/ambivalent attitudes should be more predictive of proattitudinal information seeking. Although ambivalent attitude structure might weaken the attitude's effect on seeking proattitudinal information, we believe that conflicted attitudes might also motivate attitude-congruent selective exposure because proattitudinal information should be effective in reducing ambivalence. Two studies provide evidence that the effects of ambivalence on information choices depend on amount of issue knowledge. That is, ambivalence motivates attitude-consistent exposure when issue knowledge is relatively low because less familiar information is perceived to be effective at reducing ambivalence. Conversely, when knowledge is relatively high, more unambivalent (univalent) attitudes predicted attitude-consistent information seeking.

    Full Text Available Literature suggests that the effect of winter birth on vulnerability to schizophrenia might be mediated by increased expression of proinflammatory cytokines due to prenatal infection and its inadequate regulation by anti-inflammatory factors. As the response of the immune system depends on genotype, this study assessed the interaction effects of cytokine genes and season of birth (SOB on schizotypy measured with the Schizotypal Personality Questionnaire (SPQ-74. We searched for associations of IL1B rs16944, IL4 rs2243250, and IL-1RN VNTR polymorphisms, SOB, and their interactions with the SPQ-74 total score in a sample of 278 healthy individuals. A significant effect of the IL4 X SOB interaction was found, p=0.007 and η2=0.028. We confirmed this effect using an extended sample of 373 individuals. Homozygotes CC born in winter showed the highest SPQ total score and differed significantly from winter-born T allele carriers, p=0.049. This difference was demonstrated for cognitive-perceptual and disorganized but not interpersonal dimensions. The findings are consistent with the hypothesis that the cytokine genes by SOB interaction can influence variability of schizotypal traits in the general population. The IL4 T allele appeared to have a protective effect against the development of positive and disorganized schizotypal traits in winter-born individuals.

A significant effect of the IL4 X SOB interaction was found, p = 0.007 and η 2 = 0.028. We confirmed this effect using an extended sample of 373 individuals. Homozygotes CC born in winter showed the highest SPQ total score and differed significantly from winter-born T allele carriers, p = 0.049. This difference was demonstrated for cognitive-perceptual and disorganized but not interpersonal dimensions. The findings are consistent with the hypothesis that the cytokine genes by SOB interaction can influence variability of schizotypal traits in the general population. The IL4 T allele appeared to have a protective effect against the development of positive and disorganized schizotypal traits in winter-born individuals.

    This study investigates the role of attitudinal ambivalence in moderating the effects of junk food advertisements on behavioral intentions by tapping different facets of this construct-felt ambivalence, potential ambivalence, and affective-cognitive ambivalence. Results based on an online survey of college students indicate that attention to junk food advertisements has an indirect positive effect on intentions to eat junk food through its positive effect on attitudes toward junk food. A moderated mediation model reveals that this indirect effect of junk food advertisements is weakened as respondents' levels of felt ambivalence increase. This moderating role is not observed for the measures of potential ambivalence and affective-cognitive ambivalence. Implications are discussed for health interventions.

    Prior research exploring the relationship between evaluations and body movements has focused on one-sided evaluations. However, people regularly encounter objects or situations about which they simultaneously hold both positive and negative views, which results in the experience of ambivalence. Such experiences are often described in physical terms: For example, people say they are "wavering" between two sides of an issue or are "torn." Building on this observation, we designed two studies to explore the relationship between the experience of ambivalence and side-to-side movement, or wavering. In Study 1, we used a Wii Balance Board to measure movement and found that people who are experiencing ambivalence move from side to side more than people who are not experiencing ambivalence. In Study 2, we induced body movement to explore the reverse relationship and found that when people are made to move from side to side, their experiences of ambivalence are enhanced.

    The social attitudes and interpersonal relationships of patients with obsessive-compulsive disorder (OCD) are subject to a longstanding controversy. Whereas cognitive-behavioural researchers emphasize exaggerated pro-social attitudes in OCD like inflated responsibility and worry for other people (especially significant others), dynamic theories traditionally focus on anti-social attitudes such as latent aggression and hostility. In two recent studies, we gathered support not only for a co-existence of these seemingly opposing attitudes in OCD, but also for a functional connection: inflated responsibility in part appears to serve as a coping strategy (or “defense”) against negative interpersonal feelings. In the present study, we tested a shortened version of the Responsibility and Interpersonal Behaviours and Attitudes Questionnaire (RIBAQ-R). The scale was administered to 34 participants with OCD and 34 healthy controls. The questionnaire concurrently measures pro-social and anti-social interpersonal attitudes across three subscales. In line with our prior studies, patients displayed higher scores on both exaggerated pro-social attitudes (e.g. “I suffer from a strict conscience concerning my relatives”) as well as latent aggression (e.g. “Sometimes I would like to harm strangers on the street“) and suspiciousness/distrust (e.g. “I cannot even trust my own family”). A total of 59% of the patients but only 12% of the healthy controls showed marked interpersonal ambivalence (defined as scores higher than one standard deviation from the mean of the nonclinical controls on both the prosocial and at least one of the two anti-social subscales). The study asserts high interpersonal ambivalence in OCD. Further research is required to pinpoint both the dynamic and causal links between opposing interpersonal styles. Normalization and social competence training may prove beneficial to resolve the apparent problems of patients with OCD regarding anger

  1. Ambivalence, prejudice and negative behavioural tendencies towards out-groups: The moderating role of attitude basis.

    Costarelli, Sandro; Gerłowska, Justyna

    2015-01-01

    Two experiments explored the relations between prejudice (suppression), (cognitive) ambivalence and negative behavioural tendencies towards out-groups. The current work argues that expressing out-group ambivalence based on cognitive, but not affective, information is a strategy to justify one's otherwise suppressed prejudice, which may ultimately "cover" the discriminatory nature of out-group-directed negative behavioural tendencies. Two experiments show that (1) participants evaluating the out-group in a normative context inducing prejudice suppression are more likely to self-report ambivalent beliefs rather than ambivalent emotions concerning the out-group as compared with participants whose prejudice expression is induced and (2) high-prejudice participants compared with low-prejudice participants are more prone to out-group-directed negative behavioural tendencies when these latter are self-reported after the expression of ambivalent beliefs but not ambivalent emotions concerning the out-group, and when the expression of their prejudicial evaluations is salient but not when it is not. In light of the extent to which ambivalent attitudes towards out-groups are often seamlessly integrated into public discourse, the implications of the findings are discussed not only for intergroup research but also at the societal level.

    This paper reports on the development and the psychometric properties of short forms of Ambivalent Sexism Scales toward women (ASI; Glick & Fiske, 1996) and men (AMI; Glick & Fiske, 1999), and a scale measuring rape stereotypes (IRMA; McMahon & Farmer, 2011). The short form AMI/ASI were applied for examining gender and educational differences in university students (N = 512) and in high school students (N = 1381), and for predicting individual differences in rape stereotypes in the latter. The short forms demonstrated good to excellent psychometric properties across samples of emerging adults. Relative to female students, male students reported markedly more hostility toward women and more stereotypical beliefs about rape. Despite sampling from a highly gender egalitarian and secular culture, these gender differences are on a par with those reported internationally. Rape stereotypes were predicted by sexism in high school students. Additional predictors were educational program, relationship status, and acceptance of derogatory sexual slurs. The paper questions the validity of separate constructs for benevolent sexism toward women versus men. The short form versions of the scales may substitute the original versions in future research, and help prevent attrition while measuring the same constructs. © 2017 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

  4. The evolution of autistic-like and schizotypal traits: A sexual selection hypothesis

    Directory of Open Access Journals (Sweden)

    Marco Del Giudice

    2010-08-01

    Full Text Available In this paper we present a new hypothesis on the evolution of autistic-like and schizotypal personality traits. We argue that autistic-like and schizotypal traits contribute in opposite ways to individual differences in reproductive and mating strategies, and have been maintained – at least in part – by sexual selection through mate choice. Whereas positive schizotypy can be seen as a psychological phenotype oriented to high mating effort and good genes displays in both sexes, autistic-like traits in their non-pathological form contribute to a male-typical strategy geared toward high parental investment, low mating effort, and long-term resource allocation. At the evolutionary-genetic level, this sexual selection hypothesis is consistent with Crespi and Badcock’s “imprinted brain” theory of autism and psychosis; the effect of offspring mating behavior on resource flow within the family connects sexual selection with genomic imprinting in the context of human biparental care. We conclude by presenting the results of an empirical study testing one of the predictions derived from our hypothesis. In a sample of 200 college students, autistic-like traits predicted lower interest in short-term mating, higher partner-specific investment, and stronger commitment to long-term romantic relations, whereas positive schizotypy showed the opposite pattern of effects.

  6. Testing measurement invariance of the schizotypal personality questionnaire-brief scores across Spanish and Swiss adolescents.

    Directory of Open Access Journals (Sweden)

    Javier Ortuño-Sierra

    Full Text Available BACKGROUND: Schizotypy is a complex construct intimately related to psychosis. Empirical evidence indicates that participants with high scores on schizotypal self-report are at a heightened risk for the later development of psychotic disorders. Schizotypal experiences represent the behavioural expression of liability for psychotic disorders. Previous factorial studies have shown that schizotypy is a multidimensional construct similar to that found in patients with schizophrenia. Specifically, using the Schizotypal Personality Questionnaire-Brief (SPQ-B, the three-dimensional model has been widely replicated. However, there has been no in-depth investigation of whether the dimensional structure underlying the SPQ-B scores is invariant across countries. METHODS: The main goal of this study was to examine the measurement invariance of the SPQ-B scores across Spanish and Swiss adolescents. The final sample was made up of 261 Spanish participants (51.7% men; M = 16.04 years and 241 Swiss participants (52.3% men; M = 15.94 years. RESULTS: The results indicated that Raine et al.'s three-factor model presented adequate goodness-of-fit indices. Moreover, the results supported the measurement invariance (configural and partial strong invariance of the SPQ-B scores across the two samples. Spanish participants scored higher on Interpersonal dimension than Swiss when latent means were compared. DISCUSSION: The study of measurement equivalence across countries provides preliminary evidence for the Raine et al.'s three-factor model and of the cross-cultural validity of the SPQ-B scores in adolescent population. Future studies should continue to examine the measurement invariance of the schizotypy and psychosis-risk syndromes across cultures.

  7. What is to be done with surplus embryos? Attitude formation with ambivalence in German fertility patients.

    2009-01-01

    Improved pregnancy rates in IVF have led to increasing numbers of surplus embryos which can potentially be used for purposes like donation to another infertile couple or further research. Individuals report high levels of ambivalence concerning the donation of surplus embryos. This study examined which strategies infertile patients use to deal with this ambivalence when asked to evaluate potential dispositions of surplus embryos created during IVF. Guideline-based interviews with fertility patients were audio-recorded and transcribed verbatim. Following the principle of theoretical sampling, eight interviews were analysed by use of Grounded Theory. Analyses focused on processes of individual attitude formation. Strategies for handling ambivalence during attitude formation were identified: the six strategies comprise cognitive and communicative strategies, and were integrated into a model of attitude formation under ambivalence. As ambivalence is a relevant phenomenon in attitude formation within IVF treatment, assessment of ambivalence is strongly recommended in social science studies investigating ethical problems in patient care. In the context of informed consent, there is a need for individual counselling which draws attention to the conflicting values during attitude formation. Counsellors should be aware of the signs of and the strategies to deal with ambivalence.

  8. Ambivalence about Children in the Family Building Process in Sweden

    2014-12-01

    Full Text Available Sweden provides strong support for childbearing and parenthood, including generously subsidized medical, maternal, and child care, paid parental leave, and child allowances. In this context, attitudes towards parenthood are likely to have a particularly strong impact on the decision about whether and when to have children. We examine the links between first births and holding attitudes about children, not just of positive and negative attitudes, but also of ambivalence, namely those who both value children but also value the things that compete with parenthood for young adults’ time and other resources. Our analysis shows, measuring attitudes before the transition to parenthood, that ambivalence about childbearing delays the transition to parenthood, but not nearly as much as holding purely negative attitudes. Further, reporting an ambivalent experience from the first child had no significant effect on further childbearing, which testifies to the strong two-child norm in Sweden.

    Part of the variation in personality characteristics has been attributed to the child-parent interaction and sub-optimal parenting has been associated with psychiatric morbidity. In the present study, an extensive battery of personality scales (Trait Anxiety Inventory, Behavioural Inhibition/Activation System questionnaire, Eysenck Personality Questionnaire-Revised, Temperament and Character Inventory, Schizotypal Traits Questionnaire, Toronto Alexithymia Scale) and the Parental Bonding Instrument (PBI) were administered in 324 adult healthy males to elucidate the effects of parenting on personality configuration. Personality variables were analysed using Principal Component Analysis (PCA) and the factors "Schizotypy", "Anxiety", "Behavioural activation", "Novelty seeking" and "Reward dependence" were extracted. Associations between personality factors with PBI "care" and "overprotection" scores were examined with regression analyses. Subjects were divided into "parental style" groups and personality factors were subjected to categorical analyses. "Schizotypy" and "Anxiety" were significantly predicted by high maternal overprotection and low paternal care. In addition, the Affectionless control group (low care/high overprotection) had higher "Schizotypy" and "Anxiety" compared with the Optimal Parenting group (high care/low overprotection). These results further validate sub-optimal parenting as an important environmental exposure and extend our understanding on the mechanisms by which it increases risk for psychiatric morbidity.

    Ambivalence over emotional expression (AEE) is the conflict between wanting to express emotion yet fearing the consequences of such expression. Recent literature reveals a close link between AEE and depressive symptoms among college students. Although cancer survivors experience intense emotions, few studies have examined the relationship between AEE and depressive symptoms and the underlying mechanisms among cancer survivors. Furthermore, relevant research is absent among Asians, whose culture discourages emotional expression. The present study investigated AEE's associations with depressive symptoms in Asian breast cancer survivors, and examined intrusive thoughts as a mediator. Intrusive thoughts are repetitive and unwanted thoughts about stressful events. We hypothesized that AEE would increase intrusive thoughts which in turn would increase depressive symptoms. A total of 118 Chinese American breast cancer survivors completed a questionnaire packet containing the Ambivalence over Emotional Expression Questionnaire (AEQ), Brief Symptom Inventory (BSI), and the Impact of Event Scale (IES). AEE was positively associated with depressive symptoms (β=.45, pChinese breast cancer survivors who are highly ambivalent over emotional expression may have increased risk for depressive symptoms, and such relationships can be partially explained by a cognitive mechanism: intrusive thoughts. Future research may explore other mediators and design interventions specifically targeted at reducing AEE and intrusive thoughts with the ultimate goal of reducing depression. Copyright © 2015.

    2014-02-01

    Full Text Available This article illuminates the essence of Neonatal Intensive Care Unit (NICU nurses’ attitudes in skin-to-skin care (SSC practice for preterm infants and their parents. Health care providers are in a unique position to influence the dynamic between infants and parents, and SSC affects both partners in the dyad. The design is descriptively phenomenological in terms of reflective lifeworld approach. Eighteen Swedish, Danish, and Norwegian nurses from NICUs offering varied possibilities and extents of SSC participated. NICU nurses’ attitudes in SSC practice are ambivalent. The nurses consider the sensory, wellness, and mutuality experiences to be primary and vital and enact SSC as much as possible. But “as much as possible” is a broad and varied concept, and their attitudes are ambivalent in terms of not always facilitating what they consider to be the optimal caring conditions. The source of NICU nurses’ ambivalent attitudes in SSC practice is a complex interplay of beliefs, norms, and evidence, which have a multidisciplinary basis. The ambivalent attitudes are, to a great extent, the result of the need to balance these multidisciplinary concerns. This needs to be acknowledged in considering SSC practice, as well as acknowledging that clinical judgments concerning optimal SSC depend on parents and infants unlimited access to each other, which NICU nurses can influence.

  12. Affect and self-efficacy infuse the experience of ambivalent photographs

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Ambivalent pictures offer several interpretations of different valence-e.g., some photographs by Claudia Otto document scenes which can be perceived as sad or happy, dangerous or sweet, and so on. We show that task experiences influence the experienced valence of these images. Previous work already documented that responses to images are task-dependent and self-created insights heighten pleasure. A resulting positive mood and high self-efficacy might broaden attention to positive valence. In contrast, low self-efficacy leads to the prediction of negative task experiences and strengthens the salience of a positive experience. In our study, participants rated the valence of ambivalent photographs to be more positive after positive feedback regarding the accomplishment of a precedent puzzle. We revealed a trend of positive feedback being more effective when it followed negative experiences. The experience of ambivalent images is strongly linked to mood and self-efficacy and both is influenced by taskexperiences in psycho-aesthetic studies.

    Research on family relations has extensively used the intergenerational solidarity model proposed by Bengtson and colleagues. Recently, the relevance of this model for explaining changes in family relations has been questioned, and the concept of intergenerational ambivalence has been proposed as a relevant addition to the model, supposedly acting as a catalyst, and thus serving as an explanation for changes in family relations. This study tests both the viability of the intergenerational solidarity model and the hypothesized effect of ambivalence employing longitudinal data. We use data from 2 waves of the Netherlands' Kinship Panel Study on parent-adult child relationships to estimate latent variable structural equation models. Affection, association, and support between family members are core, mutually reinforcing dimensions of solidarity. The hypothesis that ambivalence is a catalyst for change in family relations was not confirmed. Adding conflict separately revealed that it only affects the core solidarity dimensions but is itself, like normative and structural solidarity, not influenced by them. The relevance of the concept of intergenerational ambivalence for studying changes in family relations can be questioned. The viability of the intergenerational solidarity model is, however, confirmed. The concept of intergenerational ambivalence might be further explored in qualitative studies on family change.

    2014-01-01

    Client ambivalence about change (or motivation) is regarded as central to outcomes in cognitive behavioral therapy (CBT). However, little research has been conducted to examine the impact of client ambivalence about change on therapy process variables such as the therapeutic alliance. Given the demonstrated limitations of self-report measures of key constructs such as ambivalence and motivation, the present study instead employed a newly adapted observational measure of client ambivalence. Client statements regarding change (change talk (CT) and counter-change talk (CCT)) were coded in early (session 1 or 2) therapy sessions of CBT for generalized anxiety disorder. The frequency of CT and CCT was then compared between clients who later experienced an alliance rupture with their therapist, and clients who did not. The results showed that clients in dyads who later experienced an alliance rupture expressed significantly more CCT at the outset of therapy than clients who did not later experience an alliance rupture. However, CT utterances did not significantly differ between alliance rupture and no-rupture groups. CCT may strain the alliance because clients expressing higher levels of CCT early in therapy may be less receptive to therapist direction in CBT. Consequently, it is recommended that clients and therapists work together to carefully address these key moments in therapy so as to prevent alliance rupture and preserve client engagement in therapy.

    Many women experience ambivalent orientations towards chocolate, both craving for it and having concerns about eating it. The present study investigated the effect of viewing thin and overweight images of models in chocolate advertisements on ambivalent attitudes. Participants were 84 females, aged 17-63, allocated to a thin model condition, an overweight model condition, or a control group. As predicted, following exposure to their respective images, participants in the thin condition had increased avoidance, approach and guilt scores, while participants in the overweight condition had decreased approach and guilt scores, with no change in avoidance. Control participants demonstrated ambivalence, but no changes over time. The findings show that common advertising strategies for chocolate are likely to exacerbate ambivalence in female consumers.

    2013-01-01

    Gender-based structural power and heterosexual dependency produce ambivalent gender ideologies, with hostility and benevolence separately shaping close-relationship ideals. The relative importance of romanticized benevolent versus more overtly power-based hostile sexism, however, may be culturally dependent. Testing this, northeast US (N=311) and central Chinese (N=290) undergraduates rated prescriptions and proscriptions (ideals) for partners and completed Ambivalent Sexism and Ambivalence toward Men Inventories (ideologies). Multiple regressions analyses conducted on group-specific relationship ideals revealed that benevolent ideologies predicted partner ideals, in both countries, especially for US culture’s romance-oriented relationships. Hostile attitudes predicted men’s ideals, both American and Chinese, suggesting both societies’ dominant-partner advantage. PMID:23914004

    There is currently a consensus that sexism is one of the most important causes of intimate partner violence, but this has yet to be empirically demonstrated conclusively. The key objective of the study was to adapt Ambivalent Sexism Inventory (ASI) and to validate it to the Basque language. It also aims to analyze the prevalence of violence in dating relationships and verify if ambivalent sexism in young men and women is a valid predictor of perpetration and/or victimization in their dating relationships. Ambivalent Sexism Inventory and Dating Relationship Questionnaire were administered to 1378 undergraduate students (66% women and 45% Basque), aged between 17 and 30. The psychometric properties of the Basque and Spanish versions of the ASI are deemed to be acceptable. Sufficient guarantees are provided to be used as an instrument for measuring ambivalent sexism in adult Basque speakers. Ambivalent sexism among young men and women are both positively associated with the perpetration of violence and victimization in their dating relationships. However, ambivalent sexism or two sub-types of sexism (hostile and benevolent) are not relevant risk factors to be perpetrator or victim of violence in dating relationships, due to accounting for 3% or less of variance in dating violence.

    Full Text Available Despite being identified as a high risk cohort for psychosis, there has been relatively little research on the clinical presentation and assessment of Schizotypal Personality Disorder (SPD in childhood. The current study aimed to develop a measure of childhood SPD (Melbourne Assessment of Schizotypy in Kids (MASK and assess discriminant validity against another neurodevelopmental disorder, autism spectrum disorder (ASD. Sixty-eight children aged between 5 and 12 (21 SPD, 15 ASD, and 32 typically developing and their parents were administered the MASK. The MASK is a 57-item semistructured interview that obtains information from the child, their parents, and the clinician. The results showed high internal consistency for the MASK and higher scores in the SPD group. A factor analysis revealed two MASK factors: social/pragmatic symptoms and positive schizotypal symptoms. Both factors were associated with SPD, while only the social/pragmatic factor was associated with ASD. Within the two clinical groups, a receiver operating characteristic curve showed that the MASK (cut-off score: 132 out of 228 was a good indicator of SPD diagnosis. These preliminary MASK findings were reliable and consistent and suggest that childhood SPD is characterised by complex symptomology distinguishable from ASD.

    Full Text Available Schizotypy refers to a set of temporally stable traits that are observed in the general population and that resemble the signs and symptoms of schizophrenia. Here, we review evidence from studies on genetics, cognition, perception, motor and oculomotor control, brain structure, brain function and psychopharmacology in schizotypy. We specifically focused on identifying areas of overlap between schizotypy and schizophrenia. Evidence was corroborated that significant overlap exists between the two, covering the behavioural, brain structural and functional as well molecular levels. In particular, several studies showed that individuals with high levels of schizotypal traits exhibit alterations in neurocognitive task performance and underlying brain function similar to the deficits seen in patients with schizophrenia. Studies of brain structure have shown both volume reductions and increases in schizotypy, pointing to schizophrenia-like deficits as well as possible protective or compensatory mechanisms. Experimental pharmacological studies have shown that high levels of schizotypy are associated with (i enhanced dopaminergic response in striatum following administration of amphetamine and (ii improvement of cognitive performance following administration of antipsychotic compounds. Together, this body of work suggests that schizotypy shows overlap with schizophrenia across multiple behavioural and neurobiological domains, suggesting that the study of schizotypal traits may be useful in improving our understanding of the aetiology of schizophrenia.

  4. The ambivalent relationship between war and peace: public speeches concerning the issue of terrorism

    Full Text Available Following the 9/11 attacks, a coalition of West Countries, led by the United States of America, militarily occupied two countries – Afghanistan and Iraq – in part rewriting the rules which up until then had clearly outlined the difference between a war of aggression and a war of defence. By analyzing the various speeches of ten important world leaders of West Democratic Countries on terrorism of fundamentalist matrix, we will outline a contradiction: declaring the necessity of war as a condition and objective of peace. This is solved in different ways: it becomes an ambivalent strategy in the cases of Obama and Merkel, with the latter being less explicit; in the cases of Bush, Berlusconi, Blair and Rice it leads, albeit with different motivations and arguments, to a stark choice: war; whereas it disappears in the speeches of Zapatero, Prodi and Cameron, who speak of actions and strategies to combat terrorism without ever mentioning war. Without offering any value judgment of the content of the various arguments, I only take them as a pretext to reflect on the rules of ambivalent communication: a communication which starts from a clear contradiction, and argues the necessity of it, before demonstrating its usefulness and proposing strategies of action that take it into account. The essay is divided into two parts: in the first one (which is published in this issue I discuss the concept of sociological ambivalence, I distinguish ambivalence from contradictions and ambiguity and I identify the argumentative strategies of an ambivalent communication. Then I analyze the speech the President of the United States of America Barack Obama delivered on December 10, 2009 in Oslo when he received the Nobel Peace Prize as an example of “good” ambivalent communication. In the second part of the essay (which will be published in the next issue, I analyze the speeches of other world leaders as different examples of ambivalent communication.

  5. The ambivalence of losing weight after bariatric surgery

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available This study is grounded in a phenomenological lifeworld perspective. It aims at providing rich descriptions of lived experience of the process of losing weight after obesity surgery. Two women participated in in-depth interviews four times each during the first postoperative year. Based on the women's experiences, a meaning structure—the ambivalence of losing weight after obesity surgery—was identified across the women's processes of change. This consisted of five core themes: movement and activity—freedom but new demands and old restraints; eating habits and digestion—the complexity of change; appearance—smaller, but looser; social relations—stability and change; and being oneself—vulnerability and self-assurance. These core themes changed over time in terms of dominance. The experience of ambivalence is discussed according to a phenomenological perspective of the body as lived experience.

  8. Focus groups reveal consumer ambivalence.

    Science.gov (United States)

    1983-01-01

    According to qualitative research, Salvadoreans are ambivalent about the use of contraceptives. Since complete responsibility for management of the CSM project was accepted by the Association Demografica Salvadorena (ADS), the agency which operates the contraceptive social marketing project in El Salvador, in November 1980, the need for decisions in such areas as product price increases, introduction of new condom brands, promotion of the vaginal foaming tablet, and assessment of product sales performance had arisen. The ICSMP funded market research, completed during 1983, was intended to provide the data on which such decisions by ADS could be based. The qualitative research involved 8 focus groups, comprised of men and women, aged 18-45, contraceptive users and nonusers, from the middle and lower socioeconomic strata of the city of San Salvador and other suburban areas. In each group a moderator led discussion of family planning and probed respondents for specific attitudes, knowledge, and behavior regarding the use of contraceptives. To assess attitudes at a more emotional level, moderators asked respondents to "draw" their ideas on certain issues. A marked discrepancy was revealed between respondents' intellectual responses to the issues raised in group discussion, as opposed to their feelings expressed in the drawings. Intellectually, participants responded very positively to family planning practice, but when they were asked to draw their perceptions, ambivalent feelings emerged. Drawings of both the user and the nonuser convey primarily negative aspects for either choice. The user is tense and moody toward her children; the nonuser loses her attractiveness and "dies." Figures also show drawings of some of the attitudes of single and married male participants. 1 drawing shows an incomplete and a complete circle, symbolizing a sterilized man (incomplete) and a nonsterilized man (complete). Another picture depicts a chained man who has lost his freedom

    Much debate in schizotypal research has centred on the factor structure of the Schizotypal Personality Questionnaire (SPQ), with research variously showing higher-order dimensionality consisting of two to seven dimensions. In addition, cross-cultural support for the stability of those factors remains limited. Here, we examined the factor structure of the SPQ among British and Trinidadian adults. Participants from a White British subsample (n = 351) resident in the UK and from an African Caribbean subsample (n = 284) resident in Trinidad completed the SPQ. The higher-order factor structure of the SPQ was analysed through confirmatory factor analysis, followed by multiple-group analysis for the model of best fit. Between-group differences for sex and ethnicity were investigated using multivariate analysis of variance in relation to the higher-order domains. The model of best-fit was the four-factor structure, which demonstrated measurement invariance across groups. Additionally, these data had an adequate fit for two alternative models: (a) 3-factor and (b) modified 4-factor model. The British subsample had significantly higher scores across all domains than the Trinidadian group, and men scored significantly higher on the disorganised domain than women. The four-factor structure received confirmatory support and, importantly, support for use with populations varying in ethnicity and culture.

    Income inequality undermines societies: the more inequality, the more health problems, social tensions, and the lower social mobility, trust, life expectancy. Given people’s tendency to legitimate existing social arrangements, the Stereotype Content Model (SCM) argues that ambivalence—perceiving many groups as either warm or competent, but not both—may help maintain socio-economic disparities. The association between stereotype ambivalence and income inequality in 37 cross-national samples from Europe, the Americas, Oceania, Asia, and Africa investigates how groups’ overall warmth-competence, status-competence, and competition-warmth correlations vary across societies, and whether these variations associate with income inequality (Gini index). More unequal societies report more ambivalent stereotypes, while more equal ones dislike competitive groups and do not necessarily respect them as competent. Unequal societies may need ambivalence for system stability: income inequality compensates groups with partially positive social images. PMID:23039178

    This study investigated the interactive effects of attitudinal ambivalence and health message framing on persuading people to eat less junk food. Within the heuristic-systematic model of information processing, an attitudinal ambivalence (ambivalent or univalent toward eating junk food) by health message framing (advantage- or disadvantage-framed appeals) between-subjects experiment was conducted to explore a cognitive resource-matching effect and the underlying mediation processes. Ambivalent individuals reported a higher level of cognitive elaboration than univalent individuals did. The disadvantage frame engendered more extensive cognitive elaboration than the advantage frame did. Ambivalent individuals were more persuaded by the disadvantage frame and, for them, cognitive elaboration mediated the persuasion process via the systematic route. Univalent individuals were equally persuaded by the advantage frame and the disadvantage frame and, for them, neither the perceived frame valence nor cognitive elaboration mediated persuasion. Discussion of the null results among the univalent group leads to a response-reinforcement explanation. Theoretical and practical implications are discussed.

    Not all biases are equivalent, and not all biases are uniformly negative. Two fundamental dimensions differentiate stereotyped groups in cultures across the globe: status predicts perceived competence, and cooperation predicts perceived warmth. Crossing the competence and warmth dimensions, two combinations produce ambivalent prejudices: pitied groups (often traditional women or older people) appear warm but incompetent, and envied groups (often nontraditional women or outsider entrepreneurs) appear competent but cold. Case studies in ambivalent sexism, heterosexism, racism, anti-immigrant biases, ageism, and classism illustrate both the dynamics and the management of these complex but knowable prejudices.

  15. Disentangling the impact of resistance and ambivalence on therapy outcomes in cognitive behavioural therapy for generalized anxiety disorder.

    Resistance and ambivalence about change are increasingly recognized as important determinants of treatment outcomes. Moreover, resistance and ambivalence are thought to be theoretically related in that clients who are more ambivalent about change are more likely to demonstrate resistance to the process and tasks of treatment. In the context of cognitive behavioural therapy (CBT) for generalized anxiety disorder, the present study simultaneously examined early resistance and ambivalence using two observer-based coding systems in order to determine their inter-relationship and, importantly, to investigate their relative contributions to outcome. Resistance was also coded during mid-treatment in order to investigate possible mediation pathways. Early ambivalence (clients' arguments against change or counter-change talk) was found to be no longer related to outcomes when early resistance was taken into account, suggesting that disharmony in the therapeutic relationship is more important to outcomes than ambivalence per se. Moreover, mid-treatment resistance partially mediated the relationship between early resistance and post-treatment worry severity. That is, higher early opposition to therapist direction is related to poorer outcomes, in part because it is associated with greater resistance during the working phase of CBT. The findings underscore the critical need for therapists to be sensitive to identifying resistance early and throughout treatment.

    Evaluation of the validity of personality disorder (PD) diagnostic constructs is important for the impending revision of the Diagnostic and Statistical Manual of Mental Disorders. Prior factor analytic studies have tested these constructs in cross-sectional studies, and models have been replicated longitudinally, but no study has tested a constrained longitudinal model. The authors examined 4 PDs in the Collaborative Longitudinal Personality Disorders study (schizotypal, borderline, avoidant, and obsessive-compulsive) over 7 time points (baseline, 6 months, 1 year, 2 years, 4 years, 6 years, and 10 years). Data for 2-, 4-, 6- and 10-year assessments were obtained in semistructured interviews by raters blind to prior PD diagnoses at each assessment. The latent structure of the 4 constructs was differentiated during the initial time points but became less differentiated over time as the mean levels of the constructs dropped and stability increased. Obsessive-compulsive PD became more correlated with schizotypal and borderline PD than with avoidant PD. The higher correlation among the constructs in later years may reflect greater shared base of pathology for chronic personality disorders.

    This study tracked the individual criteria of four DSM-IV personality disorders-borderline, schizotypal, avoidant, and obsessive-compulsive personality disorders-and how they change over 2 years. This clinical sample of patients with personality disorders was derived from the Collaborative Longitudinal Personality Disorders Study and included all participants with borderline, schizotypal, avoidant, or obsessive-compulsive personality disorder for whom complete 24-month blind follow-up assessments were obtained (N=474). The authors identified and rank-ordered criteria for each of the four personality disorders by their variation in prevalence and changeability (remission) over time. The most prevalent and least changeable criteria over 2 years were paranoid ideation and unusual experiences for schizotypal personality disorder, affective instability and anger for borderline personality disorder, feeling inadequate and feeling socially inept for avoidant personality disorder, and rigidity and problems delegating for obsessive-compulsive personality disorder. The least prevalent and most changeable criteria were odd behavior and constricted affect for schizotypal personality disorder, self-injury and behaviors defending against abandonment for borderline personality disorder, avoiding jobs that are interpersonal and avoiding potentially embarrassing situations for avoidant personality disorder, and miserly behaviors and strict moral behaviors for obsessive-compulsive personality disorder. These patterns highlight that within personality disorders the relatively fixed criteria are more trait-like and attitudinal, whereas the relatively intermittent criteria are more behavioral and reactive. These patterns suggest that personality disorders are hybrids of traits and symptomatic behaviors and that the interaction of these elements over time helps determine diagnostic stability. These patterns may also inform criterion selection for DSM-V.

    An enlarged volume of the pituitary gland has been reported in the schizophrenia spectrum, possibly reflecting the hypothalamic-pituitary-adrenal (HPA) hyperactivity. However, it remains largely unknown whether the pituitary size longitudinally changes in the course of the spectrum disorders. In the present study, longitudinal magnetic resonance imaging (MRI) data were obtained from 18 patients with first-episode schizophrenia, 13 patients with schizotypal disorder, and 20 healthy controls. The pituitary volume was measured at baseline and follow-up (mean, 2.7 years) scans and was compared across groups. The pituitary volume was larger in the schizophrenia patients than controls at baseline, and both patient groups had significantly larger pituitary volume than controls at follow-up. In a longitudinal comparison, both schizophrenia (3.6%/year) and schizotypal (2.7%/year) patients showed significant pituitary enlargement compared with controls (-1.8%/year). In the schizophrenia patients, greater pituitary enlargement over time was associated with less improvement of delusions and higher scores for thought disorders at the follow-up. These findings suggest that the pituitary gland exhibits ongoing volume changes during the early course of the schizophrenia spectrum as a possible marker of state-related impairments.

    The role of art as a form of productive activity has been studied in the article. It is inherent in all forms of human activity and is manifested in the independence of thought, originality of propositions and innovative initiative. Category of creativity is a key not only for understanding the dynamics of social and historical processes and prospects of the development of the individual, but also for understanding the specifics of the innovation of human activities that do not fit to the traditional norms and standards of conduct. The diversity and multidimensionality of art as a social phenomenon leads to a variety of social consequences; the creativity, which is embodied in different forms, is not only creative, but sometimes ambivalent manifestation. Ambivalent manifestation of creativity has to have in it an element of the destruction, necessary for the destruction of the obsolete conservative phenomena and the approval of a new, progressive, significantly expanding the existing borders of reality. This process is dialectical in nature, so its effects may lead to negative social manifestations.

    Glick-Fiske's (1996) Ambivalent Sexism Inventory(ASI) and a new Gender-Role Ideology in Marriage (GRIM) inventory examine ambivalent sexism toward women, predicting power-related, gender-role beliefs about mate selection and marriage norms. Mainland Chinese, 552, and 252 U.S. undergraduates participated. Results indicated that Chinese and men most endorsed hostile sexism; Chinese women more than U.S. women accepted benevolent sexism. Both Chinese genders prefer home-oriented mates (women especially seeking a provider and upholding him; men especially endorsing male-success/female-housework, male dominance, and possibly violence). Both U.S. genders prefer considerate mates (men especially seeking an attractive one). Despite gender and culture differences in means, ASI-GRIM correlations replicate across those subgroups: Benevolence predicts initial mate selection; hostility predicts subsequent marriage norms.

    Healthy functioning relies on a variety of perceptual, cognitive, emotional, and behavioral abilities that are distributed throughout the normal population. Variation in these traits define the wide range of neurodevelopmental (NDD) and neuropsychiatric (NPD) disorders. Here, we introduce a new measure for assessing these traits in typically developing children and children at risk for NDD and NPD from age 2 to 18 years. The Childhood Oxford-Liverpool Inventory of Feelings and Experiences (CO-LIFE) was created as a dimensional, parent-report measure of schizotypal and psychotic traits in the general population. Parents of 2,786 children also self-reported on an adapted version of the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE-US). The CO-LIFE resulted in continuous distributions for the total score and for each of three factor analytically-derived subscales. Item response theory (IRT) analyses indicated strong reliability across the score range for the O-LIFE-US and the CO-LIFE. Internal consistency and test-retest reliability were high across all scales. Parent-child intraclass correlations were consistent with high heritability. The scales discriminated participants who reported a lifetime psychiatric diagnosis from those who reported no diagnosis. The O-LIFE-US and CO-LIFE scores correlated positively with the Social Responsiveness Scale 2 (SRS-2) indicating good convergent validity. Like the original O-LIFE, the O-LIFE-US and the CO-LIFE are valid and reliable tools that reflect the spectrum of psychiatric and schizotypal traits in the general population. Such scales are necessary for conducting family studies that aim to examine a range of psychological and behavioral traits in both children and adults and are well-suited for the Research Domain Criteria (RDoC) initiative of the NIMH. © 2017 Association for Child and Adolescent Mental Health.

  2. Ambivalence and Ambiguity in The Autobiography of Miss Jane Pittman

    Directory of Open Access Journals (Sweden)

    Monica Michlin

    2006-05-01

    Full Text Available This close reading of the text highlights how Miss Jane, in her double role as protagonist and narrator, shows considerable ambivalence towards friend and foe alike, with the result that the apparently transparent ideological meaning of entire episodes is blurred by what some critics have merely put down to “conservatism.” I examine Miss Jane’s almost constant suppression of emotion, and frequent displays of ambivalence towards other black people; her ambiguous relationship to oppressive, but familiar whites like Albert Cluveau or Robert Samson; and her conflicted relation to black heroes and heroics. Is the leading character a variation on the “mammy” who has internalized racist figures of speech, and uses contradictory images that undermine black heroics and validate white oppression? Or is Gaines’s point to undo the “retrick” of heroics and of alienation alike, and, against of backdrop of constant, ordinary destruction of black lives, to cast the adult Miss Jane as a Brer Rabbit-like figure, for whom survival and resistance are both dialectically connected and opposed? Is there a contradiction between her “progress” towards resistance shown in the last section, and her metadiscursive comments in the present, and does her literally walking out of her own story give a conclusive meaning to her narrative, or does it point to the author’s not having been able to resolve the ambivalence and ambiguities within the text?

    For the last decades, many researchers have focused on paranormal beliefs. Beliefs in the existence of paranormal phenomena would be common and studies conducted in westernized countries have highlighted a high prevalence of individuals believing in the existence of such phenomena. Tobacyk and Milford (1984) developed the Revised Paranormal Belief Scale (RPBS) for assessing beliefs in paranormal phenomena. This 26-item self-reported questionnaire, measuring beliefs in phenomena such as witchcraft or superstition, is one of the most widely used questionnaires to assess such beliefs. While studies focusing on paranormal beliefs tend to develop, there is no French self-report instrument to assess this construct. Researchers have tried to identify specific variables that might be linked to such beliefs, and some have focused on personalities of individuals who believe in the paranormal. Schizotypy has been reported to be significantly and positively correlated with paranormal beliefs. The aim of this study was a) to validate the French version of the RPBS and b) to explore the relationship between Schizotypal Personality Disorder traits and paranormal beliefs. After being recruited using the Internet and social networks (e.g. facebook), a sample of 313 participants (mean [SD] age=31.12 [11.62]; range 18-58years) completed the Schizotypal Personality Questionnaire (SPQ-B), assessing Schizotypal Personality Disorder traits and the Revised Paranormal Belief Scale assessing paranormal beliefs. Confirmatory factor analysis (CFA) was conducted to test the proposed 7-factor structure of the RPB developed by Tobacyk. Several adjustment indices were used to evaluate the model. As the first model did not fit the original one, others models were tested. Our findings indicated that a seven-factor solution, excluding 2 items, best described the item structure: (1) spiritualism, (2) superstition, (3) witchcraft, (4) precognition, (5) traditional religious belief, (6) psi, (7) and

    2012-07-01

    The existence of diverging discourses in the media and academia on the use of prescription medications to improve cognition in healthy individuals, i.e. "cognitive enhancement" (CE) creates the need to better understand perspectives from stakeholders. This qualitative focus-group study examined perspectives from students, parents and healthcare providers on CE. Stakeholders expressed ambivalence regarding CE (i.e. reactions to, definitions of, risks, and benefits). They were reluctant to adopt analogies to performance-enhancing steroids and caffeine though these analogies were useful in discussing concepts common to the use of different performance-enhancing substances. Media coverage of CE was criticized for lack of scientific rigor, ethical clarity, and inadvertent promotion of CE. Ambivalence of stakeholders suggests fundamental discomfort with economic and social driving forces of CE. Forms of public dialogue that voice the unease and ambivalence of stakeholders should be pursued to avoid opting hastily for permissive or restrictive health policies for CE.

    People's behaviors are often guided by valenced responses to objects in the environment. Beyond positive and negative evaluations, attitudes research has documented the importance of attitude strength--qualities of an attitude that enhance or attenuate its impact and durability. Although neuroscience research has extensively investigated valence, little work exists on other related variables like metacognitive judgments about one's attitudes. It remains unclear, then, whether the various indicators of attitude strength represent a single underlying neural process or whether they reflect independent processes. To examine this, we used functional MRI (fMRI) to identify the neural correlates of attitude strength. Specifically, we focus on ambivalence and certainty, which represent metacognitive judgments that people can make about their evaluations. Although often correlated, prior neuroscience research suggests that these 2 attributes may have distinct neural underpinnings. We investigate this by having participants make evaluative judgments of visually presented words while undergoing fMRI. After scanning, participants rated the degree of ambivalence and certainty they felt regarding their attitudes toward each word. We found that these 2 judgments corresponded to distinct brain regions' activity during the process of evaluation. Ambivalence corresponded to activation in anterior cingulate cortex, dorsomedial prefrontal cortex, and posterior cingulate cortex. Certainty, however, corresponded to activation in unique areas of the precuneus/posterior cingulate cortex. These results support a model treating ambivalence and certainty as distinct, though related, attitude strength variables, and we discuss implications for both attitudes and neuroscience research.

    Childhood overweight represents a health problem, and research points towards parents as key players. The aim of this study was to deepen the knowledge of how parents of children who are overweight or obese experience their parenthood. Focus group discussions with 17 parents were analysed according to the qualitative method of modified grounded theory. The results expressed the parents' ambivalence between preventing the child's overweight and not negatively affecting the child's self-esteem. The most important issue seemed to be their concern about the child's construction of self-understanding and experiences in interaction with the environment. The parents had become uncertain of their responsibility, priorities and how to act. In conclusion, parenting a child with weight issues could be a process of loving the child the way he/she is while still wanting changes for improved health, resulting in ambivalence. In addition to traditional advice about lifestyle, many parents seem to need counselling assistance with respect to their parental role.

    Schizotypal personality disorder (SPD) symptoms or features are common in patients with psychosis and their healthy relatives. However, the long-term stability of these SPD features and therefore their constituting enduring traits underlying vulnerability to psychosis remain to be clarified. Thirty-two patients with psychotic disorders and 29 of their healthy siblings were included from the long-term follow-up study of 89 nuclear families. Participants were clinically assessed by means of a semi-structured diagnostic interview, whereas the Schizotypal Personality Questionnaire-Brief (SPQ-B) was applied for the self-assessment of SPD symptoms. The assessments were carried out upon admission to the study and at follow-up, about 10 years later. The patients had higher scores than their siblings on the SPQ-B both at baseline and follow-up. In addition, self-reported SPD symptoms remained stable over time in total scores and in all the SPQ-B subscores, except for the SPQ-B Disorganization subscale. Self-reported SPD symptoms were stable over the long term among patients with psychotic disorders and their healthy siblings. This finding provides new support for including the SPD construct as a trait measure for studies addressing both vulnerability to psychosis in first-degree relatives of patients with psychosis and long-term persistence of symptoms in patients suffering from psychosis.

    Pain catastrophizing (ie, the tendency to focus on and magnify pain sensations and feel helpless in the face of pain) is one of the most important and consistent psychological predictors of the pain experience. The present study examined, in 60 patients with osteoarthritis pain who were married or partnered: 1) the degree to which ambivalence over emotional expression and negative network orientation were associated with pain catastrophizing, and 2) whether self-efficacy for pain communication moderated these relations. Hierarchical multiple linear regression analyses revealed a significant main effect for the association between ambivalence over emotional expression and pain catastrophizing; as ambivalence over emotional expression increased, the degree of pain catastrophizing increased. In addition, the interaction between ambivalence over emotional expression and self-efficacy for pain communication was significant, such that as self-efficacy for pain communication increased, the association between ambivalence over emotional expression and pain catastrophizing became weaker. Negative network orientation was not significantly associated with pain catastrophizing. Findings suggest that higher levels of self-efficacy for pain communication may help weaken the effects of ambivalence over emotional expression on pain catastrophizing. In light of these results, patients may benefit from interventions that target pain communication processes and emotion regulation. This article examines interpersonal processes involved in pain catastrophizing. This study has the potential to lead to better understanding of maladaptive pain coping strategies and possibly better prevention and treatment strategies. Copyright © 2018 The American Pain Society.

    It is unresolved whether avoidant personality disorder (APD) is an independent schizophrenia (Sz)-spectrum personality disorder (PD). Some studies find APD and social anxiety symptoms (Sxs) to be a separable dimension of psychopathology in relatives (Rels) of schizophrenics while other studies find avoidant Sxs to be correlated with schizotypal and paranoid Sxs.

  13. Solidarity-conflict and ambivalence: testing two conceptual frameworks and their impact on quality of life for older family members.

    2007-03-01

    The purpose of this study was to test empirically two major conceptualizations of parent-child relations in later adulthood-intergenerational solidarity-conflict and ambivalence paradigms-and their predictive validity on elders' quality of life using comparative cross-national data. Data were from a sample of 2,064 elders (aged 75 and older) from the five-country OASIS study (Old Age and Autonomy: The Role of Service Systems and Intergenerational Family Solidarity; Norway, England, Germany, Spain, and Israel). Multivariate and block-recursive regression models estimated the predictivity of the two conceptualizations of family dynamics on quality of life controlling for country, personal characteristics, and activity of daily living functioning. Descriptive analyses indicated that family solidarity, especially the affective/cognitive component (called Solidarity A), was high in all five countries, whereas conflict and ambivalence were low. When I entered all three constructs into the regression Solidarity A, reciprocal intergenerational support and ambivalence predicted quality of life. Controlling for activity of daily living functioning, socioeconomics status, and country, intergenerational relations had only a weak explanatory power, and personal resources explained most of the variance. The data suggest that the three constructs exist simultaneously but in varying combinations, confirming that in cross-cultural contexts family cohesion predominates, albeit with low degrees of conflict and ambivalence. The solidarity construct evidenced relatively robust measurement. More work is required to enhance the ambivalence measurement.

  14. AN AMBIVALENT CONRAD IN AN OUTPOST OF PROGRESS

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available The present paper aims to portray the racist and anti-racist dimensions of Joseph Conrad in his short story “An Outpost of Progress” (1897. Conrad’s alleged racist status espoused by thinkers such as Chinua Achebe and Edward Said, particularly in Heart of Darkness, has constantly been the subject of heated debates in literature. A myriad of analogous traces in the short story “An Outpost of Progress” lend Conrad’s voice to a highly racist position while many other anti-racist traces observed in the story could lower the resonance of the same voice, hence an inconclusive ambivalence or a liminal position in Conrad’s tone. This paper is thus divided into two sections. The first section has the racist traces of Conrad in the short story on top of its agenda whereas the second section ventures into the anti-racist footprints of Conrad’s voice in the story. In so doing, this paper sets out to turn to Achebe and Said in arguing for the racist position of Conrad; however, the anti-racist facets of the story will be substantiated via relying on the arguments developed by thinkers such as D. C. R. A. Goonetilleke and Benita Parry. An ironic ambivalence swaying from a racist tone to an anti-racist tone in Conrad’s voice in “An Outpost of Progress” is the conclusive maxim.

  15. Ambivalent stereotypes of nurses and physicians: impact on students' attitude toward interprofessional education.

    Nurse-physician stereotypes have been proposed as a factor hindering interprofessional collaboration among practitioners and interprofessional learning among nursing and medical students. Using socio-psychological theories about ambivalent stereotypes, the present work aimed to analyse: a) the content of nurse and physician stereotypes held by nursing and medical students and b) the role of auto-stereotype on students' attitude toward interprofessional education (IPE).  Methods. A cross-sectional on-line survey was adopted and a questionnaire was emailed to 205 nursing students and 151 medical students attending an Italian university. Nursing and medical students shared the stereotypical belief that nurses are warmer but less competent than physicians. Nurses and physicians were basically depicted with ambivalent stereotypes: nurses were seen as communal, socially competent and caring but less competent, not agentic and less autonomous, while physicians were seen as agentic, competent and autonomous, but less communal, less collectivist and less socially competent. Moreover, a professional stereotypical image impacted the students' attitude toward IPE. More precisely, when nurses and physicians were seen with classic ambivalent stereotypes, both nursing and medical students were less favourable towards interprofessional education programmes. The content of professional stereotypes of healthcare students was still linked to classical views of nurses as caring and physicians as curing. This seemed to limit students' attitude and intention to be engaged in IPE.

    Tensions are normative in the parent and adult child relationship, but there is little research on the topics that cause the most tension or whether tensions are associated with overall relationship quality. Adult sons and daughters, aged 22 to 49, and their mothers and fathers (N = 158 families, 474 individuals) reported the intensity of different tension topics and relationship quality (solidarity and ambivalence) with one another. Tensions varied between and within families by generation, gender and age of offspring. In comparison to tensions regarding individual issues, tensions regarding the relationship were associated with lower affective solidarity and greater ambivalence. Findings are consistent with the developmental schism hypothesis, which indicates that parent-child tensions are common and are the result of discrepancies in developmental needs which vary by generation, gender, and age.

    Community stakeholders express a range of opinions about supervised injection facilities (SIFs). We sought to identify reasons for ambivalence about SIFs amongst community stakeholders in two Canadian cities. We used purposive sampling methods to recruit various stakeholder representatives (n = 141) for key informant interviews or focus group discussions. Data were analyzed using a thematic process. We identified seven reasons for ambivalence about SIFs: lack of personal knowledge of evidence about SIFs; concern that SIF goals are too narrow and the need for a comprehensive response to drug use; uncertainty that the community drug problem is large enough to warrant a SIF(s); the need to know more about the "right" places to locate a SIF(s) to avoid damaging communities or businesses; worry that a SIF(s) will renew problems that existed prior to gentrification; concern that resources for drug use prevention and treatment efforts will be diverted to pay for a SIF(s); and concern that SIF implementation must include evaluation, community consultation, and an explicit commitment to discontinue a SIF(s) in the event of adverse outcomes. Stakeholders desire evidence about potential SIF impacts relevant to local contexts and that addresses perceived potential harms. Stakeholders would also like to see SIFs situated within a comprehensive response to drug use. Future research should determine the relative importance of these concerns and optimal approaches to address them to help guide decision-making about SIFs.

  18. Ambivalent sexism, attitudes towards menstruation and menstrual cycle-related symptoms.

    2014-08-01

    The objective of the present study was to investigate the relationship between ambivalent sexism and beliefs and attitudes towards menstruation, and, in turn, to study the influence of these variables on menstrual cycle-related symptoms. One hundred and six Mexican women completed the Ambivalent Sexism Inventory, the Beliefs about and Attitudes toward Menstruation Questionnaire and the Menstrual Distress Questionnaire. The higher scores on benevolent sexism were associated with the most positive attitudes towards menstruation and also with the belief that a menstruating woman should or should not do some activities and that menstruation keeps women from their daily activities. The higher scores on hostile sexism were associated with rejection of menstruation as well as with feelings of embarrassment about it. Beliefs about and attitudes towards menstruation predicted menstrual cycle-related symptoms related to negative affect, impaired concentration and behavioural changes, but did not predict somatic symptoms. These results will be useful to health professionals and advocates who want to change the negative expectations and stereotypes of premenstrual and menstrual women and reduce the sexism and negative attitudes towards women that are evident in Mexican culture. © 2013 International Union of Psychological Science.

    The present publication is dedicated to renewable energies. The move to a new energy and climate policy impinges on many central humanistic issues (including issues of a legal, economic, sociological, ethical and politological nature). How is it possible to resolve the ambivalences that are associated with the use of renewable energies and which draw our attention not only to renewable energies as such but also to issues of energy efficiency and sufficiency. What political and economic instruments are needed in order to accelerate the market entry of renewable energies and at the same time contain the ambivalences associated with them? And what questions of legal interpretation result from the application of such instruments in practice, be it in the context of subsidies under the Renewable Energy Law or the laws on the planning of building projects. And where lie the causes of the fact seen here that so many individuals in business, the political realm and the public at large are finding it hard to go with the transition to renewable energies?.

    This study tested predictions regarding ambivalent sexism, previously studied cross-culturally, here "within-culturally", between groups from different organizational settings. Based on three samples (334 adults in general, 744 industrial employees, and 189 high school students), completing a Swedish version of the Ambivalent Sexism Inventory (ASI), the results revealed that men scored higher on hostile and benevolent sexism than women, and high school students scored higher than both adult samples on both forms of sexism. The results generally confirmed the predictions; the gender gap in benevolent sexism decreased as a function of increasing levels of general sexism and the correlation between hostile and benevolent sexism decreased with higher levels of general sexism. In fact, the groups scoring highest on general sexism displayed significant negative correlations indicating a polarized ideology of women among these groups. Implications, both theoretical and practical, derived from these results are discussed. © 2011 The Authors. Scandinavian Journal of Psychology © 2011 The Scandinavian Psychological Associations.

    According to the Development of Early Adult Romantic Relationships (DEARR) model (Bryant, C. M., & Conger, R. D. [2002]. Conger, R. D., Cui, M., Bryant, C. M., & Elder, G. H., Jr. [2000] interactional characteristics in the family of origin influence early adult romantic relationships by promoting or inhibiting the development of interpersonal competencies that contribute to relationship success in young adulthood. The present study uses the DEARR model as a general framework to help examine the long-term link between parental discipline practices in adolescence and young adult's interactions in the early years of marriage or cohabitation. Using prospective data from 288 target participants, their families, and their romantic partner, beginning when the targets were adolescents and continuing up to the fifth year of their marital or cohabiting relationships, we found empirical support for the DEARR model. Parental discipline practices in adolescence were associated with romantic relationship quality during the early years of marriage or cohabitation through processes in late adolescence and young adulthood. Specifically, harsh and inconsistent discipline practices were associated with greater attitudinal ambivalence toward parents in adolescence. Inconsistent discipline was also associated with higher risks of externalizing problems during late adolescence years. Externalizing problems and ambivalence toward parents predicted poorer relationship quality through aggressive behaviors and ambivalence toward a romantic partner during the early years of marriage or cohabitation. Implications for practitioners working with couples and families are discussed.

    Section III of DSM-5 includes an alternative model for personality disorders comprising five higher-order pathological personality traits, four of which resemble domains from the Big Five/Five-Factor Model of Personality (FFM). There has, however, been considerable debate regarding the association of FFM Openness-to-Experience/Intellect (OE/I) with DSM-5 Psychoticism and Schizotypal Personality Disorder (STPD). The authors identify several limitations in the literature, including inattention to (a) differences in the conceptualization of OE/I in the questionnaire and lexical traditions and (b) the symptom heterogeneity of STPD. They then address these limitations in two large patient samples. The results suggest that OE/I per se is weakly associated with Psychoticism and STPD symptoms. However, unique variance specific to the different conceptualizations of OE/I demonstrates much stronger associations, often in opposing directions. These results clarify the debate and the seemingly discrepant views that OE/I is unrelated to Psychoticism and contains variance relevant to Psychoticism.

    Patricide is the murder of one of the parents. We report a case of a man who had committed two homicides, at different times, one of them being considered a parricide. He was referred for forensic psychiatric evaluation and later evaluated in a psychiatric assistance service. Psychiatric interview was carried out and the final psychiatric diagnosis was established based on the DSM-IV-TR criteria and retrospective analysis of forensic and clinical records. The court appointed forensic experts concluded that the patient suffered from schizotypical disorder, presenting cognitive and volitive impairment. He was found not guilty by reason of insanity. Later, in a second assessment, being in a psychiatric assistance service, the patient received a diagnosis of paranoid schizophrenia. The determination of criminal responsibility is essential to the proper disposition of convicted persons in any system of criminal law that protects human rights.

    Schizotypy has been proposed to be the expression of genetic vulnerability to schizophrenia. The available literature shows cognitive similarities between schizotypy and schizophrenia, with mildly impaired performance being associated with schizotypy. This study aims to determine the relationship between schizotypy and cognitive performance in siblings of patients with psychosis. Schizotypal features and cognitive performance on a neuropsychological battery were compared between 48 siblings of patients with psychosis and 44 healthy controls. The relationships between schizotypy and cognitive performance were analysed by controlling the condition of being a sibling. Siblings showed poorer performance on vigilance/sustained attention (M = 37.6; SD = 7.1) and selective attention/interference control/working memory (M = 23.28; SD = 2.7) tasks. The variance in vigilance/sustained attention performance was explained, at 30%, by the interpersonal factor of schizotypy on the suspiciousness dimension and the condition of being a sibling. Interpersonal features of schizotypy in siblings of patients with psychosis are associated with deficits in vigilance/sustained attention performance. Copyright © 2017 Elsevier B.V.

    Autism and schizophrenia spectrum research is typically based on coarse diagnostic classification, which overlooks individual variation within clinical groups. This method limits the identification of underlying cognitive, genetic and neural correlates of specific symptom dimensions. This study, therefore, aimed to identify homogenous subclinical subgroups of specific autistic and schizotypal traits dimensions, that may be utilised to establish more effective diagnostic and treatment practices. Latent profile analysis of subscale scores derived from an autism-schizotypy questionnaire, completed by 1678 subclinical adults aged 18-40 years (1250 females), identified a local optimum of eight population clusters: High, Moderate and Low Psychosocial Difficulties; High, Moderate and Low Autism-Schizotypy; High Psychosis-Proneness; and Moderate Schizotypy. These subgroups represent the convergent and discriminant dimensions of autism and schizotypy in the subclinical population, and highlight the importance of examining subgroups of specific symptom characteristics across these spectra in order to identify the underlying genetic and neural correlates that can be utilised to advance diagnostic and treatment practices.

  9. When love meets drugs: pharmaceuticalizing ambivalence in post-socialist China.

    Ma, Zhiying

    2012-03-01

    In this article, I examine the interaction between intimacy and psychiatry to explore the ambivalences in the use of pharmaceuticals in psychiatric practice. Of particular interest is how pharmaceuticals come to constitute in multiple ways what pathology is and what form of life needs to be restored, and how psychiatric medications reconfigure the ambivalence of intimacy in post-socialist China. Following the life of Mei, a female psychiatric patient, for two years, I have made a series of discoveries related to medicine and intimacy in China. Specifically, I show that psychopharmaceuticals indicate a diseased body that threatens the intimate bond. They also highlight a socially suffering subject that is in lack of love from the intimate partner who demands the latter's redemption. I discuss how these multiple and contradicting meanings of psychopharmaceuticals and intimacy are socio-historically situated. Thus, while previous research in medical anthropology criticizes pharmaceuticalization for reducing the socio-political life (bios) to a biological body (zoē), I argue that these life forms co-exist in a pharmaceutical "zone of indistinction" (Agamben, Homo Sacer: Sovereign Power and Bare Life. Stanford University Press, Stanford, 1998), in which they constitute and contradict each other. This discussion warns researchers against falling back into the usual orientation of either biomedicine or the social sciences.

    Full Text Available Objective To analyze the determinants of emergency contraception non-use among women in unplanned and ambivalent pregnancies. Method Cross-sectional study with a probabilistic sample of 366 pregnant women from 12 primary health care units in the city of São Paulo, Brazil. A multinomial logistic regression was performed, comparing three groups: women who used emergency contraception to prevent ongoing pregnancies (reference; women who made no use of emergency contraception, but used other contraceptive methods; and women who made no use of any contraceptive methods at all. Results Cohabitation with a partner was the common determinant of emergency contraception non-use. No pregnancy risk awareness, ambivalent pregnancies and no previous use of emergency contraception also contributed to emergency contraception non-use. Conclusion Apart from what is pointed out in the literature, knowledge of emergency contraception and the fertile period were not associated to its use.

  11. The positive emotions that facilitate the fulfillment of needs may not be positive emotions at all: the role of ambivalence.

    2015-01-01

    According to some scholars, if individuals experience over three times as many positive emotions as negative emotions, they are more likely to thrive. We contend, however, that perhaps positive and negative emotions that overlap in time are likely to enhance wellbeing. Specifically, if positive and negative emotions are experienced simultaneously rather than separately-called ambivalent emotions-the fundamental needs of individuals are fulfilled more frequently. Considerable evidence supports this perspective. First, many emotions that enhance wellbeing, although classified as positive, also coincide with negative feelings. Second, ambivalent emotions, rather than positive or negative emotions separately, facilitate creativity and resilience. Third, ambivalent emotions activate distinct cognitive systems that enable individuals to form attainable goals, refine their skills, and enhance their relationships. Copyright © 2015 Elsevier Inc.

  12. Sleep spindles are related to schizotypal personality traits and thalamic glutamine/glutamate in healthy subjects.

    Schizophrenia is a severe mental disorder affecting approximately 1% of the worldwide population. Yet, schizophrenia-like experiences (schizotypy) are very common in the healthy population, indicating a continuum between normal mental functioning and the psychosis found in schizophrenic patients. A continuum between schizotypy and schizophrenia would be supported if they share the same neurobiological origin. Two such neurobiological markers of schizophrenia are: (1) a reduction of sleep spindles (12-15 Hz oscillations during nonrapid eye movement sleep), likely reflecting deficits in thalamo-cortical circuits and (2) increased glutamine and glutamate (Glx) levels in the thalamus. Thus, this study aimed to investigate whether sleep spindles and Glx levels are related to schizotypal personality traits in healthy subjects. Twenty young male subjects underwent 2 all-night sleep electroencephalography recordings (128 electrodes). Sleep spindles were detected automatically. After those 2 nights, thalamic Glx levels were measured by magnetic resonance spectroscopy. Subjects completed a magical ideation scale to assess schizotypy. Sleep spindle density was negatively correlated with magical ideation (r = -.64, P .1). The common relationship of sleep spindle density with schizotypy and thalamic Glx levels indicates a neurobiological overlap between nonclinical schizotypy and schizophrenia. Thus, sleep spindle density and magical ideation may reflect the anatomy and efficiency of the thalamo-cortical system that shows pronounced impairment in patients with schizophrenia. © The Author 2014.

    2004-01-01

    It is often argued that adolescents who become pregnant do not sufficiently appreciate the negative consequences, and that prevention programs should target participants' attitudes toward pregnancy. Data from the first two waves of the National Longitudinal Study of Adolescent Health were used to examine whether 15-19-year-old females' attitudes toward pregnancy influence their contraceptive consistency and their risk of pregnancy. Characteristics and attitudes associated with pregnancy and contraceptive use were assessed using bivariate and multivariate analysis. Twenty percent of female adolescents were defined as having antipregnancy attitudes, 8% as having propregnancy attitudes and 14% as being ambivalent toward pregnancy; the remainder were considered to have mainstream attitudes. Among sexually experienced adolescents, having an attitude toward pregnancy was not associated with risk of pregnancy. However, those who were ambivalent about pregnancy had reduced odds of using contraceptives consistently and inconsistently rather than not practicing contraception at all (odds ratios, 0.5 and 0.4, respectively). Antipregnancy respondents did not differ from proprepregancy respondents in terms of their contraceptive consistency. However, having a positive attitude toward contraception was associated with increased likelihood of inconsistent and consistent contraceptive use compared with nonuse (1.6 and 2.1, respectively). Programs designed to prevent pregnancy need to give young women information about pregnancy and opportunities to discuss the topic so that they form opinions. Furthermore, programs should emphasize positive attitudes toward contraception, because effective contraceptive use is shaped by such attitudes and is strongly associated with reduction of pregnancy risk.

    The classical symptom specificity hypothesis (Blatt, 1974) particularly associates obsessional symptoms to interpersonal behavior directed at autonomy and separation from others. Cross-sectional group research, however, has yielded inconsistent findings on this predicted association, and a previous empirical case study (Cornelis et al., in press; see Chapter 2) documented obsessional pathology to be rooted in profound ambivalences between autonomous and dependent interpersonal dynamics. Therefore, in the present empirical case study, concrete operationalizations of the classical symptom specificity hypothesis are contrasted to alternative hypotheses based on the observed complexities in Chapter 2. Dynamic associations between obsessional symptoms and interpersonal functioning is further explored, aiming at further contribution to theory building (i.e., through suggestions for potential hypothesis-refinement; Stiles, 2009). Similar to the first empirical case study (Chapter 1), Consensual Qualitative Research for Case studies is used to quantitatively and qualitatively describe the longitudinal, clinical interplay between obsessional symptoms and interpersonal dynamics throughout the process of supportive-expressive psychodynamic therapy. In line with findings from Chapter 1, findings reveal close associations between obsessions and interpersonal dynamics, and therapist interventions focusing on interpersonal conflicts are documented as related to interpersonal and symptomatic alterations. Observations predominantly accord to the ambivalence-hypothesis rather than to the classical symptom specificity hypothesis. Yet, meaningful differences are observed in concrete manifestations of interpersonal ambivalences within significant relationships. Findings are again discussed in light of conceptual and methodological considerations; and limitations and future research indications are addressed.

    Full Text Available This essay explores Gadamer’s ambivalent relationship with modernity.  Gadamer is a prominent critic of the Enlightenment project.  His criticisms are both theoretical and practical.  Theoretically, representationalism is at the center of modern epistemology for Gadamer.  Practically, Gadamer sees the demotion of prudence (phronesis as fundamental to the “bad” Enlightenment.  Gadamer’s attempt to revive an appreciation of rhetoric is a way to the join the theoretical and practical dimensions of speech and life. The central representative philosopher of the Enlightenment for Gadamer is Kant.  The antithetical thinker is Aristotle.  Gadamer would have his Kant and his Aristotle too.  The tension between these is at the heart of Gadamer’s philosophical hermeneutics.

    Full Text Available The increasing presence of women in the public sphere has provoked cultural changes that affect social cognition. These changes implicate social organizations such as the Military. Focusing the interest in approaching modern forms of prejudice in terms of gender inequalities, we studied ambivalent sexism attitudes, values and social dominance orientation in a sample of 238 males and females from the National Military School training to become officials. Results show the presence of sexist attitudes. In sex roles and gender typing, female participants show an androgynous stereotype probably related to the need to present themselves closer to men in order to assume leadership.

    Objective The quality of one’s personal relationships has been linked to morbidity and mortality across different diseases. As a result, it is important to examine more integrative mechanisms that might link relationships across diverse physical health outcomes. In this study, we examine associations between relationships and telomeres which predict general disease risk. These questions are pursued in the context of a more comprehensive model of relationships that highlights the importance of jointly considering positive and negative aspects of social ties. Method 136 individuals from a community sample (ages 48 to 77) completed the social relationships index which allows a determination of relationships that differ in their positive and negative substrates (i.e., ambivalent, supportive, aversive, indifferent). Telomere length was determined from peripheral blood mononuclear cells via quantitative PCR. Results Participants who had a higher number of ambivalent ties in their social networks evidenced shorter telomeres. These results were independent of other relationships types (e.g., supportive), as well as standard control variables (e.g., age, health behaviors, medication use). Gender moderated the links between ambivalent ties and telomere length with these associations seen primarily in women. Follow-up analyses revealed that the links between ambivalent ties and telomeres were primarily due to friendships, parents, and social acquaintances. Conclusions Consistent with epidemiological findings, these data highlight a novel and integrative biological mechanism by which social ties may impact health across diseases, and further suggests the importance of incorporating both positivity and negativity in the study of specific relationships and physical health.

    To assess the efficacy and tolerability of pericyazine in the treatment of patients with mental disorders manifesting with psychopathic-like symptoms and correction of pathocharacterological disorders in patients with personality disorders during the short-term admission to the hospital or the long-term outpatient treatment. Sixty-three patients with schizotypal personality disorder and organic personality disorder with psychopathic-like symptoms and pathocharacterological changes within the diagnosis of dissocial personality disorder and borderline personality disorder were examined. Patients received pericyazine during the short-term admission to the hospital (6 weeks) or the long-term outpatient treatment (6 month). Efficacy, tolerability and compliance were assessed in the study. Treatment with pricyazine was effective in all patients. The improvement was seen in patients with organic personality disorders and patients with personality disorders (psychopathy). The maximal effect was observed in inpatients and this effect remained during outpatient treatment. The improvement of mental state of patients with schizotypal personality disorder achieved during inpatient treatment with pericyazine continued during the long-term outpatient treatment. Side-effects were restricted to extrapyramidal symptoms, the frequency of metabolic syndrome was low. During outpatient treatment, the compliance was higher if the patient was managed by the same psychiatrist during inpatient- and outpatient treatment.

    The purpose of this study was to understand the effect that individual characteristics have on consumer advertising processing under high- and low-interactivity circumstances on the Web. Tests on the relationship between individual differences and advertising responses form the basis of this empirical study on the Web. The results indicated that consumers have a higher tendency to avoid or experience ambivalence about Internet advertisements under low-interactivity circumstances, and attitudinal ambivalence lead to avoidance when responding to advertisements on the Internet. Personality variables are the main factors in consumer decision-making behaviors and Internet characteristics, such as levels of interactivity, can greatly influence the effectiveness of advertising in online environments. Advertising credibility could influence people's consumer attitudes, beliefs, or behaviors over time on the Web.

    Full Text Available http://dx.doi.org/10.5007/2175-8026.2016v69n2p63 This article aims to investigate the visual representation of the connection between immigration and the construction of an Australian identity as a nation in Shaun Tan’s graphic novel The Arrival (2006. Based on the debate about imagined communities and the ambivalence on the narration of a nation, proposed by Benedict Anderson and Homi Bhabha, we will discuss how The Arrival creates moments for the appearance of the ambivalence of cultural difference at the same time that it also constructs a horizontal imagined community. On these terms, The Arrival depicts some of the liminal positionality that immigrants have to deal when they arrive in a new place, but also constructs a cohesive and homogeneous narrative that entails the assimilation of the immigrants. In other words, this work offers a closure that can be read as an assimilation of the colonial discourse for a series post-colonial issues.

    Ambivalence over emotional expression (AEE) is the inner conflict of desiring emotion expression and fearing consequence of emotion expression. Few studies to date have examined the effects of AEE within an ethnic group that prioritizes emotional self-control. The present study examined the associations between AEE and well-being (viz., quality of life and depressive symptoms) as a function of acculturation among a sample of Chinese American breast cancer survivors. Ninety-six Chinese breast cancer survivors (M age  = 54.64 years old, SD = 7.98) were recruited from Southern California. Participants filled out a paper-pen questionnaire containing the Ambivalence over Emotional Expression Questionnaire (AEQ), the Functional Assessment of Cancer Therapy-Breast (FACT-B), and the Center for Epidemiologic Studies Depression Scale-Short Form (CESD-10). Acculturation was a statistically significant moderator of the relations between AEE and depressive symptoms, and a statistically marginally significant moderator of the relations between AEE and quality of life. Simple slopes revealed that AEE was negatively associated with quality of life (B = -.45, p acculturation, but not associated for women with low acculturation (Bs = -.15 and .04, ps > .05, for quality of life and depressive symptoms, respectively). These results suggest that less acculturated Chinese breast cancer survivors are protected by Chinese cultural values of emotional self-control and restraint, and thus do not experience the detrimental effects of AEE on their depressive symptoms and quality of life. Implications are discussed.

    The main goal of the present study was to test the measurement equivalence of the Schizotypal Personality Questionnaire - Brief Revised (SPQ-BR) scores in a large sample of Spanish and American non-clinical young adults. The sample was made up of 5,625 young adults (M = 19.65 years; SD = 2.53; 38.5% males). Study of the internal structure, using confirmatory factor analysis (CFA), revealed that SPQ-BR items were grouped in a theoretical internal structure of nine first-order factors. Moreover, three or four second-order factor and bifactor models showed adequate goodness-of-fit indices. Multigroup CFA showed that the nine lower-order factor models of the SPQ-BR had configural and weak measurement invariance and partial strong measurement invariance across country. The reliability of the SPQ-BR scores, estimated with omega, ranged from 0.67 to 0.91. Using the item response theory framework, the SPQ-BR provides more accurate information at the medium and high end of the latent trait. Statistically significant differences were found in the raw scores of the SPQ-BR subscales and dimensions across samples. The American group scored higher than the Spanish group in all SPQ-BR domains except Ideas of Reference and Suspiciousness. The finding of comparable factor structure in cross-cultural samples would lend further support to the continuum model of psychosis spectrum disorders. In addition, these results provide new information about the factor structure of schizotypal traits and support the validity and utility of this measure in cross-cultural research.

    Background Superior temporal gyrus (STG/BA22) volume is reduced in schizophrenia and to a milder degree in schizotypal personality disorder (SPD), representing a less severe disorder in the schizophrenia-spectrum. SPD and Borderline personality disorder (BPD) are severe personality disorders characterized by social and cognitive dysfunction. However, while SPD is characterized by social withdrawal/anhedonia, BPD is marked by hyper-reactivity to interpersonal stimuli and hyper-emotionality. This is the first morphometric study to directly compare SPD and BPD patients in temporal volume. Methods We compared three age-gender- and education-matched groups: 27 unmedicated SPD individuals with no BPD traits, 52 unmedicated BPD individuals with no SPD traits, and 45 healthy controls. We examined gray matter volume of frontal and temporal lobe Brodmann areas (BAs), and dorsal/ventral amygdala from 3T magnetic resonance imaging. Results In the STG, an auditory association area reported to be dysfunctional in SPD and BPD, the SPD patients had significantly smaller volume than healthy controls and BPD patients. No group differences were found between BPD patients and controls. Smaller BA22 volume was associated with greater symptom severity in SPD patients. Reduced STG volume may be an important endophenotype for schizophrenia-spectrum disorders. SPD is distinct from BPD in terms of STG volume abnormalities which may reflect different underlying pathophysiological mechanisms and could help discriminate between them. PMID:19473820

    The authors examined the stability of schizotypal (STPD), borderline (BPD), avoidant (AVPD) and obsessive– compulsive (OCPD) personality disorders (PDs) over 2 years of prospective multiwave follow-up. Six hundred thirty-three participants recruited at 4 collaborating sites who met criteria for 1 or more of the 4 PDs or for major depressive disorder (MDD) without PD were assessed with semistructured interviews at baseline, 6, 12, and 24 months. Lifetable survival analyses revealed that the PD groups had slower time to remission than the MDD group. Categorically, PD remission rates range from 50% (AVPD) to 61% (STPD) for dropping below diagnostic threshold on a blind 24-month reassessment but range from 23% (STPD) to 38% (OCPD) for a more stringent definition of improvement. Dimensionally, these findings suggest that PDs may be characterized by maladaptive trait constellations that are stable in their structure (individual differences) but can change in severity or expression over time.

    Schizotypal personality disorder (SPD) individuals and borderline personality disorder (BPD) individuals have been reported to show neuropsychological impairments and abnormalities in brain structure. However, relationships between neuropsychological function and brain structure in these groups are not well understood. This study compared visual-spatial working memory (SWM) and its associations with dorsolateral prefrontal cortex (DLPFC) and ventrolateral prefrontal cortex (VLPFC) gray matter volume in 18 unmedicated SPD patients with no BPD traits, 18 unmedicated BPD patients with no SPD traits, and 16 healthy controls (HC). Results showed impaired SWM in SPD but not BPD, compared with HC. Moreover, among the HC group, but not SPD patients, better SWM performance was associated with larger VLPFC (BA44/45) gray matter volume (Fisher's Z p-values <0.05). Findings suggest spatial working memory impairments may be a core neuropsychological deficit specific to SPD patients and highlight the role of VLPFC subcomponents in normal and dysfunctional memory performance.

    Suspiciousness is a common feature of schizophrenia. However, suspicious thoughts are also commonly experienced by the general population. This study aimed to examine the underlying neural mechanism of suspicious thoughts in individuals with and without schizotypal personality disorder (SPD)-proneness, using an event-related potential (ERP) paradigm. Electroencephalography (EEG) was recorded when the "feeling of being seen through" was evoked in the participants. The findings showed a prominent positive deflection of the difference wave within the time window 250-400 ms after stimuli presentation in both SPD-prone and non-SPD-prone groups. Furthermore, the P3 amplitude was significantly reduced in the SPD-prone group compared to the non-SPD-prone group. The current density analysis also indicated hypoactivity in both frontal and temporal regions in the SPD-prone group, suggesting that the frontotemporal cortical network may play a role in the onset of suspicious thoughts. The P3 of difference wave was inversely correlated with the cognitive-perception factor and the suspiciousness/paranoid ideation trait, which provided preliminary electrophysiological evidence for the association of suspiciousness with SPD features.

    2017-12-01

    This paper explores the ambivalence of the Next Generation Science Standards (NGSS) and its Framework towards neoliberal governance. The paper examines the ways that the NGSS serves as a mechanism within neoliberal governance: in its production of disposable populations through testing and through the infusion of engineering throughout the NGSS to resolve social problems through technical fixes. However, the NGSS, like earlier standards, is reactionary to forces diminishing the power of institutional science (e.g., the AAAS) including neoliberal prioritizing market value over evidence. The NGSS explicitly takes on neoliberal junk science such as the anti-global-warming Heartland Institute.

    In an exploration of the schizophrenia spectrum, we compared cortical metabolic rates in unmedicated patients with schizophrenia and schizotypal personality disorder (SPD) with findings in age- and sex-matched normal volunteers. Coregistered magnetic resonance imaging (MRI) and positron emission tomography (PET) scans were obtained in 27 schizophrenic, 13 SPD, and 32 normal volunteers who performed a serial verbal learning test during tracer uptake. A template of Brodmann areas derived from a whole brain histological section atlas was used to analyze PET findings. Significantly lower metabolic rates were found in prefrontal areas 44-46 in schizophrenic patients than in normal volunteers. SPD patients did not differ from normal volunteers in most lateral frontal regions, but they had values intermediate between those of normal volunteers and schizophrenic patients in lateral temporal regions. SPD patients showed higher than normal metabolic rates in both medial frontal and medial temporal areas. Metabolic rates in Brodmann area 10 were distinctly higher in SPD patients than in either normal volunteers or schizophrenic patients.

    Using data from the Durham Child Health and Development Study (n=148), the current study examines the associations between child and parenting variables at 6 months and child attachment quality at 12 months of age and maternal report of child self regulation at 24 months of age. Child and parent variables predicted distinct forms of insecure attachment relationships. Observations of infant soothability during the reunion session of the Face-to-Face Still Face Paradigm at 6 months differentially predicted children with later insecure-ambivalent attachments from those with secure attachments. Observations of maternal negative intrusiveness at 6 months of age differentially predicted children with insecure-avoidant attachments from those with secure attachments. Maternal sensitivity at 6 months was associated with maternal report of child affective problems at 24 months, but this association was moderated by infant negativity during soothing and later moderated by child attachment quality. Collectively, these results suggest the following two mutually exclusive possibilities regarding infant soothability and later ambivalent attachment quality: either infant soothability is a unique and distinct predictor of later ambivalent attachment quality and this cascade represents a developmental shift in child risk during the first year of life, or that infant soothability following a stressful task at 6 months of age is itself an early indicator of ambivalent attachment behavior with the mother. The data from the current study could not provide differential support for one possibility over the other. Copyright © 2012 Elsevier Inc. All rights reserved.

    2009-01-01

    Research on the role of organizational and psychosocial factors in influencing risk behaviors and the likelihood of injury at work showed that safety climate also has great impact on workers' behavior. However, the mechanisms through which this impact operates are still partially unclear. In order to explore the role that attitudinal ambivalence toward wearing PPE might play in mediating the impact of safety climate on safety norm violations, a questionnaire was administered to 345 Italian workers. Three dimensions of safety climate (i.e., company safety concern, senior managers' safety concern, supervisors' attitudes towards safety) were found to be positively associated with the individual ambivalence level, whereas the fourth one (i.e., work pressure) was negatively correlated with it. In turn, low levels of ambivalence were associated with a lower tendency to break the safety norms, even though the perception of a good safety climate also maintained a direct effect on unsafe behaviors. Designers of training program for the prevention of work related injuries must pay great attention to the psycho-social factors (such as the effects of the safety climate perception by employees on their attitudes and behaviors), and include specific contents into the prevention programs in order to improve workers compliance with safety norms.

    We assessed correlates of obsessive-compulsive (OCPD), schizotypal (SPD) and borderline (BPD) personality disorders in 110 obsessive-compulsive disorder (OCD) patients. We found OCD patients with OCPD (20.9%) to exhibit higher rates of hoarding and bipolar disorders, increased severity of hoarding and symmetry, lower prevalence of unacceptable thoughts involving sex and religion and less non-planning impulsivity. Conversely, OCD patients with SPD (13.6%) displayed more frequently bipolar disorder, increased severity of depression and OCD neutralization, greater prevalence of "low-order" behaviors (i.e., touching), lower low-planning impulsivity and greater "behavioral" compulsivity. Finally, in exploratory analyses, OCD patients with BPD (21.8%) exhibited lower education, higher rates of several comorbid psychiatric disorders, greater frequency of compulsions involving interpersonal domains (e.g. reassurance seeking), increased severity of depression, anxiety and OCD dimensions other than symmetry and hoarding, more motor and non-planning impulsivity, and greater "cognitive" compulsivity. These findings highlight the importance of assessing personality disorders in OCD samples. Copyright © 2015 Elsevier Ltd. All rights reserved.

  17. The symbolic constitution of addiction: language, alienation, ambivalence.

    Science.gov (United States)

    Kemp, Ryan

    2012-07-01

    The author offers an articulation of addiction, via existential-phenomenology and Lacanian psychoanalysis, where it is argued that the addicted subject is constituted via a symbolic structuring evolving from societal practices, laws and the effects of language. Language carries a heritage, which bears on the knowledge and practices of designated subjects and practitioners of that discourse. Addiction, as one particular form of embodied existence and knowledgeable practice, finds expression through the speech and habits of the addict. Addiction, it is argued, is symbolically saturated with ambivalence and alienation. Also the addict is described as the complete modern technocratic subject, consumed by the ideology of consumption. The clinical implications are briefly explored where it is noted that two major approaches to addiction, namely 12-step fellowships and motivational interviewing, both attend to language as a critical component of their treatment approach.

    Full Text Available This paper represents a thorough phase in the effort to identify and assort the strengths and weaknesses of e-learning educational services. This paper reviews a synthesis of the assessments on the e-learning educational services through a survey of the specialized literature from 2000 to 2012 in order to identify the strengths and weaknesses of e-learning educational services which were reported during the past decade. The steps of our approach are the following: 1. The identification of a large number of specialized studies that analyze the above mentioned issue; 2. A basic theoretical review of the research from the perspective of identifying the strengths and weaknesses of the e-learning educational services and some of their implications on the intellectual development of the beneficiaries; 3. A descriptive statistical data analysis which is carried out in order to extract information about strengths and weaknesses relevant to the literature taken into consideration; 4. Results classification and interpretation; 5. Formulating practical suggestions for the notion of e-learning educational services considering the development of studies on the impact of their use on the intellectual development of the beneficiaries. The study results highlighted that strengths and weaknesses are not 'pure', but ambivalent, simultaneously incorporating meanings and limits with different weights. A predictive model of future e-learning educational services can be designed on the basis of the results obtained in the research. This predictive model is based on a pedagogical concept that takes into account the ambivalence of the higher indices which have been identified.

    Full Text Available The article is devoted to the search for more accurate psycho-diagnostic methods and assessment tools for determining the degree of cognitive deficits in patients with schizophrenic disorders. The concepts of "cognitive deficits" and "cognitive profile", understood as the ratio of intact and damaged components of cognitive processes and their schematic representation are discussed. The authors substantiate the need for a clear gradation of cognitive impairments in schizophrenia, development of universal translation algorithms of traditional qualitative results (meaningful analysis of violations of cognitive activity in quantitative indicators. The article is based on the results of experimental psychological study. The investigation involved 128 patients: 76 people with Paranoid schizophrenia (F20 according to ICD-10 and 52 persons with Schizotypal disorder (F21 according to ICD-10. To assess the cognitive deficit, both traditional domestic methods and foreign tests, rarely used in the practice of a medical psychologist were conducted. The study analyzed the difference in cognitive tests performance between groups of patients with several types of schizophrenia and with different disease duration (up to 5 years and more. On the basis of quantitative data, a "cognitive profile" was lined for each disease. As a result, different variants of cognitive deficits, depending on the shape and course of the disease have been identified. The structure and dynamics of the cognitive deficits associated with schizophrenia and various forms depending on the different duration of the disease is described in detail. Also cognitive profiles compiled on this basis.

  1. Relationships between Ambivalent Sexism and the Five Moral Foundations in Domestic Violence: Is it a Matter of Fairness and Authority?

    Ambivalent sexism has served to justify and maintain patriarchy and traditional gender roles characterized by inequality and male domination in the intimate partner violence (IPV) literature; according to the Moral Foundation Theory (MFT) there are two specific moral foundations related to inequality and domination: fairness and authority. We connect these separate fields arguing that sexist attitudes can be related to specific patterns of endorsement of the five moral foundations. Our hypothesis is that ambivalent sexism in men convicted of violence against the partner may be rooted in at least these two moral foundations, and that at least these two moral foundations may also serve to predict intention to change the violent behavior against the partner. Controlling for political orientation, the results show that benevolent sexism correlates positively with the authority foundation; and hostile sexism correlates negatively with the fairness foundation. Both foundations contribute to explaining the two dimensions of ambivalent sexism (benevolent and hostile) and only the fairness foundation predict intention to change the violent behavior against the partner. New treatment approaches could be designed to increase moral concerns about fairness and to reduce moral concerns about authority in people who, at least, have once used violence against their partners.

    Interpersonal deviance is central to the theory of and research on schizotypal psychopathology. The present study investigated interpersonal deviance and its corresponding impact among hypothetically schizotypic, or schizophrenia-prone, men, defined by high scores on the Perceptual Aberration-Magical Ideation (Per-Mag) Scale. In a videotaped interview, high-scoring Ss relative to control Ss were rated as more odd (p scale and suggest that interpersonal factors may influence the eventual adjustment of high-scoring individuals.

    College students in southeastern Mexico (n = 185) and the northeastern United States (n = 96) utilized a semantic differential scale to rate subtypes of women: a menstruating woman, a menopausal woman, a pregnant woman, a premenstrual woman, a woman with a hysterectomy, a teenage girl, a woman in love, and a woman with a young baby. Americans reported significantly more negative attitudes than Mexicans did toward a menstruating woman, a premenstrual woman, a teenage girl, and a pregnant woman. Participants chose more positive words to describe a teenage girl, a woman in love, a pregnant woman, and a woman with a young baby, which is suggestive of a pronatal bias. Participants also completed the Ambivalent Sexism Inventory (ASI). Men scored significantly higher than women on hostile sexism. Mexicans scored significantly higher than Americans on both hostile and benevolent sexism. Sexism scores are related to attitudes toward premenstrual, menstruating, and menopausal women; women with a hysterectomy; and women with a young baby.

  4. Ambivalent journey: Teacher career paths in Oman

    This study investigated the career paths of 625 university graduates who prepared to be secondary school teachers in Oman, their assessment of their current work situation, and the extent to which their initial commitment to teaching was related to their subsequent career satisfaction and intention to remain in teaching. While nearly all graduates entered teaching, their decision was marked by ambivalence. Nearly half of the graduates reported being only somewhat or not at all committed to teaching as a career when they graduated. It also appears that initial commitment to teaching operates as an important lens through which teachers view their subsequent careers. Those initially more committed to teaching were more likely to be satisfied with the progress they made in their career, more likely to think that their current teaching position offered them opportunities for advancement, and more likely to want to remain in teaching than were graduates who had a lower initial commitment to teaching. The authors discuss both the theoretical and practical implications of these findings.

We argue that this ambivalence is not specific to religious claims but inherent to all public claims about best solutions and fundamental questions in politics. The problem is not the claim......In the debate about the return of religion in politics, religious actors and discourses are viewed with a certain concern. Whereas some defend the peaceful effects of religion, most contributions understand religious truth claims as a challenge to democratic pluralism that presents a tendency...... make strong religious truth claims contributing to peace-building and reconciliation during conflicts where religion was an important dimension: the apparitions of Medjugorje in Bosnia-Herzegovina and the movement of Sant'Egidio in Algeria....

  6. How can group experience influence the cue priority? A re-examination of the ambiguity-ambivalence hypothesis

    Full Text Available Since the discovery of the "framing effect" by Kahneman and Tversky, the sensitivity of the "framing effect"---its appearance and in some cases its disappearance---has long been an object of study. However there is little agreement as to the reasons for this sensitivity. The "ambiguity-ambivalence hypothesis" (Wang, 2008 aims to systematically explain the sensitivity of this effect by paying particular attention to people's cue priority: it states that the framing effect occurs when verbal framing is used to compensate for the absence of higher prioritized decision cues. The main purpose of our study is to examine and develop this hypothesis by examining cue priority given differences in people's "group experience". The main result is that the framing effect is absent when the choice problem is presented in a group context that reflects the actual size of the group that the participant has had experience with. Thus, in order to understand the choices that people make in life and death decisions, it is important to incorporate the decision maker's group experience explicitly into the ambiguity-ambivalence hypothesis.

    2013-03-01

    Full Text Available This paper examines and evaluates representations of problematic sisterly relationships in twentieth-century Irish women’s stories which display an emphasis on ambivalence and sibling rivalry.  The paper is based primarily on the literary output of Mary Lavin, Clare Boylan, Moy McCrory, Éilís Ní Dhuibhne, Jan Kennedy, Mary Morrissy and Claire Keegan.  The paper seeks, by reference both to feminist studies and Irish women’s short stories, to demonstrate the consequences and causes of a divided sisterhood which itself may be traced back to a suppression of expression of female solidarity embedded in western culture and manifested in western literary heritage.  Typically, such stories depict a conflict sourced in the need to develop self-identity and framed within the constraints imposed by separate social roles.  This kind of conflict results potentially in rivalry, antagonism, ambivalence, and the domination of one sibling by another.  Daughters/sisters are often depicted in these stories both as competing with each other for limited resources and also as seeking a sense of personal identity through mutual polarisation.  There are also stories into which are woven undertones of domination disguised as sisterly closeness, for which the actual motivation seems to be a repressed aspiration for intimacy.

    Although the majority of rape survivors do not label their experiences as rape (i.e., unacknowledged rape), the literature is mixed in terms of how this affects survivors' psychological functioning. To elucidate the discrepancies, the present study examined the interaction between rape acknowledgement and ambivalent sexism in relation to depression and posttraumatic stress disorder (PTSD) symptoms. The analyzed sample included 128 female rape survivors who were drawn from a larger college sample of 1,595 participants. The participants completed measures of sexual assault experiences, ambivalent sexism, and depression and PTSD symptoms. The results supported a significant interaction between acknowledgement status and benevolent sexism in relation to both depression and PTSD symptoms. Conversely, the present study failed to find support for an interaction between acknowledgment status and hostile sexism. The clinical implications suggest that rather than seeing acknowledging rape as essential to the recovery process, clinicians should assess for and take into account other factors that may contribute to psychological functioning. Additionally, the findings support that more complex models of trauma recovery should be investigated with the goal of working toward a more comprehensive understanding of the longitudinal process of rape acknowledgment. © 2016 Wiley Periodicals, Inc.

    Full Text Available Diplomats are civil servants who represent their governments abroad. By the nature of their work, diplomats work in multicultural environments. Working in intercultural settings can involve grey areas, paradoxes, and a wide range of emotions. This article analyzes how diplomats construct their professional identity, how they approach intercultural diversity and how they manage ambivalence. Qualitative interviews with senior diplomats as well as a review of literature from multiple disciplines indicate that it is vital for diplomats to be highly skilled in self-management; in building and maintaining relationships; and in operating in intercultural environments. We argue that it is essential to include these emotional, social, and cultural competences in diplomatic training so that diplomats may become effective bridge-builders. This will be particularly relevant for a diplomat whose country is currently involved in a conflict with another country, as well as for diplomats who work in the context of a political conflict.

    2018-03-01

    Full Text Available Jhumpa Lahiri’s Interpreter of Maladies is a collection of short stories which, for the most part, deals with the identity crisis of the Indian Americans who are trapped in-between their Indian heritage and the American culture. The crisis is manifest in their unremitting struggle to preserve, to integrate, and to adjust. The collection, due to its dealing with the in-between-ness, ambivalence, hybridity, and marginality of the displaced Indian Americans, is receptive to the postcolonial studies. This essay draws on the relevant ideas and concepts in the field of the diaspora identity to examine Lahiri's “A Temporary Matter,” “When Mr. Pirzada Came to Dine,” “Sexy,” and “This Blessed House” which portray identity crisis of the second-generation Bengali migrants. The ultimate objective is to investigate into the nature of the internal ambivalence of Lahiri's second-generation characters caused by the reciprocal influence of Host/Guest relationships. The significance of the present study is twofold; on the one hand, it accentuates the intellectual attention to the crisis of identity felt by the exponentially increasing second-generation diaspora; on the other hand, it attempts to attract concentrated scholarly interest in diaspora ambivalence which is one of Lahiri scholars’ less addressed concerns.

    It is unresolved whether avoidant personality disorder (APD) is an independent schizophrenia (Sz)-spectrum personality disorder (PD). Some studies find APD and social anxiety symptoms (Sxs) to be separable dimensions of psychopathology in relatives (Rels) of schizophrenics while other studies find avoidant Sxs to be correlated with schizotypal and paranoid Sxs. Rates of APD among first-degree Rels of Sz probands, attention-deficit/hyperactivity disorder (ADHD) probands, and community control (CC) probands were examined. Further analyses examined rates when controlling for the presence of schizotypal (SPD) and paranoid (PPD) personality disorders, differences in APD Sxs between relative groups, and whether APD in Rels of Szs reflects a near miss for another Sz-spectrum PD. Three hundred sixty-two first-degree Rels of Sz probands, 201 relatives of ADHD probands, and 245 Rels of CC probands were interviewed for the presence of DSM-III-R Axis I and II disorders. Diagnoses, integrating family history, interview information, and medical records, were determined. APD occurred more frequently in Rels of Sz probands compared to CC probands (pavoids social or occupational activities..." and "exaggerates the potential difficulties..." 65% of the Rels of Sz probands who had diagnoses of APD were more than one criterion short of a DSM-III-R diagnosis of either SPD or PPD. This indicates that APD is a separate Sz-spectrum disorder, and not merely a sub-clinical form of SPD or PPD.

  12. A tainted trade? Moral ambivalence and legitimation work in the private security industry.

    2011-06-01

    The private security industry is often represented - and typically represents itself - as an expanding business, confident of its place in the world and sure of its ability to meet a rising demand for security. But closer inspection of the ways in which industry players talk about its past, present and future suggests that this self-promotion is accompanied by unease about the industry's condition and legitimacy. In this paper, we analyse the self-understandings of those who sell security - as revealed in interviews conducted with key industry players and in a range of trade materials - in order to highlight and dissect the constitutive elements of this ambivalence. This analysis begins by describing the reputational problems that are currently thought to beset the industry and the underlying fears about its status and worth that these difficulties disclose. We then examine how security players seek to legitimate the industry using various narratives of professionalization. Four such narratives are identified - regulation, education, association and borrowing - each of which seeks to justify private security and enhance the industry's social worth. What is striking about these legitimation claims is that they tend not to justify the selling of security in market terms. In conclusion we ask why this is the case and argue that market justifications are 'closed-off' by a moral ambivalence that attaches to an industry trading in products which cannot guarantee to deliver the condition that its consumers crave. © London School of Economics and Political Science 2011.

    In the general concept of self-disturbances in schizophrenia and schizophrenia spectrum disorders, somatopsychic depersonalization (SPD) occupies a special place as it constitutes a syndrome that comprises feelings of detachment from one's own body and mental processes. However, apart from clinical descriptions, to date the pathophysiology of SPD is not fully understood due to the rareness of the syndrome and a lack of experimental studies. In a case study of one patient with schizotypal disorder, we applied a multimodal approach to understanding the SPD phenomena. The patient's clinical profile was identified as disruption of implicit bodily function, accompanied by depressive symptoms. On a neuropsychological level, the patient exhibited impairment in executive functioning, intact tactile perception and kinesthetic praxis. Behavioral tests revealed an altered sense of time but unimpaired self-agency. Furthermore, the patient exhibited a lack of empathy and he had autistic traits, although with a sufficient ability to verbalize his feelings. On the neurobiological level using an active and passive touch paradigm during functional magnetic resonance imaging (fMRI), we found a hyperconnectivity of the default-mode network and salience network and a hypoconnectivity of the central executive brain networks in the performance of the touch task as well as intact perceptual touch processing emerging from the direct comparisons of the touch conditions. Our data provide evidence for the important role of altered large-brain network functioning in SPD that corresponds to the specific behavioral and neurocognitive phenomena. © 2015 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

  14. Role conflict and ambivalence in the aged-parent-adult-child relationship

    Full Text Available Purpose – The parent-child relationship is important to the solidarity of families and the emotional well-being of family members. Since people are more dependent on their close social relationships as they age, understanding the quality of relationships between aged parents and their adult children is a critical topic. Previous research shows that this relationship is complicated with both kinship and ambivalence. However, there is little research on the causes of this complexity. This paper proposes a role model to explain this complexity by studying the leadership transition within a family as the child grows. Design/methodology/approach – In this paper, we proposed a novel perception to understand this transition process and explain related problems based on the analysis of the leader-follower relationship between the parents and their children. Findings – When a child is born, his/her parents become the leader of this family because of their abilities, responsibilities and the requirements of the infant. This leader-follower role structure will last a long time in this family. Decades later, when the parents become old and the child grows up, the inter-generational contracts within the family and the requirement of each members change. This transition weakens the foundation of the traditional leader-follower role structure within the family. If either the parent or the child does not want to accept their new roles, both of them will suffer and struggle in this relationship. This role conflict will cause ambivalence in the relationship between aged parents and their adult children. Originality/value – Based on the quantitative study model provided in this paper, we can moderate the relationships between aged parents and their adult children. This effort is meaningful in enhancing the quality of life and emotional wellbeing for senior citizens.

    Full Text Available Salman Rushdie’s memoirs, essays and novels contribute to the appreciation of the contradictions in his outlook on life. His experiences in his family enable Rushdie to make efforts for objective and tolerant judgement of British lifestyle and culture. However, his isolation from the society in Britain despite his struggle for adaptation to British cultural values cause contradictions in his cultural identity. While Rushdie expresses his allegiance to India and its culture in The Ground Beneath Her Feet (1999, he reflects his alienation from his homeland in this novel as well. Similarly, in his Imaginary Homelands (1981-1991 whereas Rushdie questions the injustice and inequality caused by imperialism in The New Empire within Britain (1982, he justifies the colonialist discourse in Kipling (1990. He elaborates on the contradictions in his outlook on life in terms of his cultural ambivalence in his fictions such as Midnight’s Children (1981 and Shame (1983. However, in his latest novel, Two Years, Eight Months and Twenty-Eight Nights (2015, Rushdie reflects his cultural identity conflict in terms of rationalism-mysticism dichotomy. With the use of allegory as well as the lack of linearity in time and space, Rushdie justifies his cultural ambivalence in relation to the dynamism of contemporary world. Thus, Rushdie’s latest novel invites reading for its representation of the oppositions in his approach to life.

    Since 2008, we witness the emergence of the Do-It-Yourself Biology movement, a global movement spreading the use of biotechnology beyond traditional academic and industrial institutions and into the lay public. Practitioners include a broad mix of amateurs, enthusiasts, students, and trained scientists. At this moment, the movement counts nearly 50 local groups, mostly in America and Europe, but also increasingly in Asia. Do-It-Yourself Bio represents a direct translation of hacking culture and practicesfrom the realm of computers and software into the realm of genes and cells. Although the movement is still in its infancy, and it is even unclear whether it will ever reach maturity, the contours of a new paradigm of knowledge production are already becoming visible. We will subsequently sketch the economic, the epistemological and the ethical profile of Do-It-Yourself Bio, and discuss its implications and also its ambivalences.

  19. Difficult Questions and Ambivalent Answers on Genetic Testing

    Directory of Open Access Journals (Sweden)

    Andréa Wiszmeg

    2012-11-01

    Full Text Available A qualitative pilot study on the attitudes of some citizens in southern Sweden toward predictive genetic testing – and a quantitative nation wide opinion poll targeting the same issues, was initiated by the Cultural Scientific Research Team of BAGADILICO. The latter is an international biomedical research environment on neurological disease at Lund University. The data of the two studies crystallized through analysis into themes around which the informants’ personal negotiations of opinions and emotions in relation to the topic centred: Concept of Risk,‘Relations and Moral Multi-layers, Worry, Agency and Autonomy, Authority, and Rationality versus Emotion. The studies indicate that even groups of people that beforehand are non-engaged in the issue, harbour complex and ambivalent emotions and opinions toward questions like this. A certain kind of situation bound pragmatism that with difficulty could be shown by quantitative methods alone emerges. This confirms our belief that methodological consideration of combining quantitative and qualitative methods is crucial for gaining a more complex representation of attitudes, as well as for problematizing the idea of a unified public open to inquiry.

    The autism and schizophrenia spectra overlap to a large degree in the social and interpersonal domains. Similarly, abnormal excitatory glutamate and inhibitory γ-aminobutyric acid (GABA) neurotransmitter concentrations have been reported for both spectra, with the interplay of these neurotransmitters important for cortical excitation to inhibition regulation. This study investigates whether these neurotransmitter abnormalities are specific to the shared symptomatology, and whether the degree of abnormality increases with increasing symptom severity. Hence, the relationship between the glutamate/GABA ratio and autism and schizophrenia spectrum traits in an unmedicated, subclinical population was investigated. A total of 37 adults (19 female, 18 male) aged 18-38 years completed the Autism Spectrum Quotient (AQ) and Schizotypal Personality Questionnaire (SPQ), and participated in the resting state proton magnetic resonance spectroscopy study in which sequences specific for quantification of glutamate and GABA+ concentration were applied to a right and left superior temporal voxel. There were significant, moderate, positive relationships between right superior temporal glutamate/GABA+ ratio and AQ, SPQ and AQ+SPQ total scores (pGABA+ coinciding with higher scores on these subscales. Only the relationships between glutamate/GABA+ ratio and Social Anxiety, Constricted Affect, Social Skills and Communication survived multiple comparison correction (pGABA+ ratio reduced with increasing restricted imagination (pschizophrenia spectra.

    Schizotypy is a psychological construct related to schizophrenia. The exact relationship between both entities is not clear. In recent years, schizophrenia has been associated with hippocampal abnormalities and spatial memory problems. The aim of this study was to determine possible links between high schizotypy (HS) and low schizotypy (LS) and spatial abilities, using virtual reality tasks. We hypothesised that the HS group would exhibit a lower performance in spatial memory tasks than the LS group. Two groups of female students were formed according to their score on the ESQUIZO-Q-A questionnaire. HS and LS subjects were tested on two different tasks: the Boxes Room task, a spatial memory task sensitive to hippocampal alterations and a spatial recognition task. Data showed that both groups mastered both tasks. Groups differed in personality features but not in spatial performance. These results provide valuable information about the schizotypy-schizophrenia connections. Schizotypal subjects are not impaired on spatial cognition and, accordingly, the schizotypy-schizophrenia relationship is not straightforward.

  2. Näitamise ambivalentne poeetika: J. G. Ballardi „Crash” / The Ambivalent Poetics of Showing in J. G. Ballard's „Crash“

    Jaak Tomberg

    2016-01-01

    My article revisits a well-known discussion about morality in J. G. Ballard's ”Crash“ that surrounded the appearance of Jean Baudrillard's essay of the same name in a special section of Science Fiction Studies (Nov 1991. In this debate N. Katherine Hayles and Vivian Sobchack strongly oppose Baudrillard's claim that there ”is no affectivity behind [the world that Crash depicts]: no psychology, no ambivalence or desire, no libido or death drive“ to Ballard's novel, and, accordingly, no moral point or warning either. In contrast, Hayles and Sobchack argue that the novel warns us about the transformative influence of contemporary technology. To shed new light on this opposition (whose sides I briefly introduce, I undertake a thorough analysis of ”Crash's“ main poetic features: the prevalence of showing over telling, the recurrence of accounts over descrip­tions, the thoroughly technical vocabulary, allusions towards transcendence, and the interpretive anxiety created by a first-person narrator that bears the author's name. I map the contrast between Ballard's disinte­rested style of writing and the apparent affective charge of his characters while showing how this contrast generates a deep ambivalence that enables both moral and morally indifferent interpretations of the novel. The reader is never told what to think about the obscene events that occur and this provokes him to make difficult moral decisions about the novel. The ambivalence of ”Crash's“ poetics has the subversive potential to dislocate and reconsider the so far predominantly marginalized role of psychopathology and perversion in contemporary techno-culture.

    Although social cognition deficits have been associated with schizophrenia, social trait judgments - or first impressions - have rarely been studied. These first impressions, formed immediately after looking at a person's face, have significant social consequences. Eighty-one individuals with schizophrenia or schizoaffective disorder and 62 control subjects rated 30 neutral faces on 10 positive or negative traits: attractive, mean, trustworthy, intelligent, dominant, fun, sociable, aggressive, emotionally stable and weird. Compared to controls, patients gave higher ratings for positive traits as well as for negative traits. Patients also demonstrated more ambivalence in their ratings. Patients who were exhibiting paranoid symptoms assigned higher intensity ratings for positive social traits than non-paranoid patients. Social trait ratings were negatively correlated with everyday problem solving skills in patients. Although patients appeared to form impressions of others in a manner similar to controls, they tended to assign higher scores for both positive and negative traits. This may help explain the social deficits observed in schizophrenia: first impressions of higher degree are harder to correct, and ambivalent attitudes may impair the motivation to interact with others. Consistent with research on paranoia and self-esteem, actively-paranoid patients' positive social traits judgments were of higher intensity than non-paranoid patients'.

    2016-12-01

    Full Text Available Background: The research of ambivalence is an actual problem of modern linguistics because of active promotion of Strategic Ambiguity as one of the key pragmatic categories on the way to understand the complexity of the concept of communicative intentions of the speaker. Generalization of conceptual and terminological findings in the Hinting Strategy of ironical utterances allows to develop the appropriate models of their practical application in the interpersonal interaction. Purpose: The purpose of the investigation is to determine the qualifying and classifying features of the irony-effect in order to demonstrate the importance of strategic ambiguity and propose a model for determining the strategically ambiguous communication. The main task of the article is to investigate the strategic ambivalence as one of the key categories of pragmatics toward understanding the complexity of the concept of intention in the speaker's communication and analyze different types of strategic ambiguity in the ironic utterances as well as the mechanisms of optimization of interpersonal interaction on the factual material of English and Ukrainian languages. Results: In the research the term strategic ambivalence refers to those communicative situations where interlocutors use ambiguity purposefully to accomplish their goals. Strategic ambiguity may be particularly useful in the interpersonal interaction. Under the circumstances of the Hinting Strategy communicative acts are often intentionally ambiguous since they allow different interpretations to coexist and therefore they are more effective in the interpersonal interaction. The communicative acts within ironical utterances are unclear and ambiguous. Although clarity is usually considered desirable for interpersonal communication, ambiguity may be more effective under the circumstances of the Hinting Stategy. Discussion: The strategic use of ambiguity minimizes the impolite speech acts. Another important

    Research on risk factors for men's perpetration of intimate partner violence (IPV) has shown a high correlation with problem alcohol use. Additional studies, however, indicate that the alcohol-IPV link is neither simple nor necessarily direct and that a range of factors may moderate this relationship. Using a national, community-based sample of 255 men, the present study examined the moderating effects of ambivalent sexism (i.e., hostile and benevolent sexism) on the relationship between alcohol use and IPV perpetration. The findings show that both greater alcohol consumption and high hostile sexism are positively associated with IPV perpetration, and that hostile sexism moderates the alcohol-IPV relationship for perpetration of physical IPV, but not for psychological IPV. Moreover, high levels of alcohol consumption have a greater impact on physical IPV perpetration for men low in hostile sexism than for men high in hostile sexism, lending support to the multiple threshold model of the alcohol-IPV link. Implications of the findings for prevention, intervention, and future research are discussed. © The Author(s) 2015.

    Full Text Available Over the last forty years, the gap between men and women with respect to labor-market outcomes, paid hours of work, hours working at home, occupations, college majors, and education levels in the United States has narrowed or disappeared. We ask whether these substantial changes in women's lives—changes in precisely the variables that have seemed to matter so much to our understanding of political participation—have enabled women's political action in the United States. We find that they have not, and we suggest that the brakes on the translation of education and occupation into political participation come from continuing ambivalence about jobs and careers. Of course, these ambivalent attitudes may very well reflect a reality about the complications of workforce participation in a world with unequal and limited access to childcare, parental leave, high-paying jobs, and opportunities for career advancement.

    Autism and schizophrenia are multi-dimensional spectrum disorders that have substantial phenotypic overlap. This overlap is readily identified in the non-clinical population, and has been conceptualised as Social Disorganisation (SD). This study investigates the balance of excitatory glutamate and inhibitory γ -aminobutyric acid (GABA) concentrations in a non-clinical sample with high and low trait SD, as glutamate and GABA abnormalities are reported across the autism and schizophrenia spectrum disorders. Participants were 18 low (10 females) and 19 high (9 females) SD scorers aged 18 to 40 years who underwent 1 H-MRS for glutamate and GABA+macromolecule (GABA+) concentrations in right and left hemisphere superior temporal (ST) voxels. Reduced GABA+ concentration ( p  = 0.03) and increased glutamate/GABA+ ratio ( p  = 0.003) in the right ST voxel for the high SD group was found, and there was increased GABA+ concentration in the left compared to right ST voxel ( p  = 0.047). Bilateral glutamate concentration was increased for the high SD group ( p  = 0.006); there was no hemisphere by group interaction ( p  = 0.772). Results suggest that a higher expression of the SD phenotype may be associated with increased glutamate/GABA+ ratio in the right ST region, which may affect speech prosody processing, and lead behavioural characteristics that are shared within the autistic and schizotypal spectra.

Por ello en esta investigación se exploran las actitudes ambivalentes hacia hombres en adolescentes mexicanos. Método: Estudio descriptivo, transversal y cuantitativo donde cuarenta y tres mujeres y treinta siete hombres, con edades comprendidas entre 12 y 19 años (M=16.61, DT=1.20, contestaron el Inventario de Sexismo Ambivalente hacia Hombres. Resultados: El análisis estadístico mostró que los chicos obtuvieron mayores niveles de sexismo benevolente hacia el hombre, mientras que en el sexismo hostil no se obtuvieron diferencias significativas entre hombres y mujeres. Conclusiones: Desde una perspectiva de género inclusiva es pertinente continuar con el estudio del sexismo hacia las mujeres y los hombres con el fin de entender las dinámicas subyacentes en la discriminación hacia ambos sexos. Por lo tanto, las actitudes hacia los hombres no deben ser consideradas como un tema de investigación irrelevante.

    The emergency department is an important gateway for the treatment of self-harm patients. Nurses\\' attitudes towards patients who self-harm can be negative and often nurses experience frustration, helplessness, ambivalence and antipathy. Patients are often dissatisfied with the care provided, and meeting with positive or negative attitudes greatly influences whether they seek additional help. A quantitative design was utilised to measure emergency department nurses\\' attitudes towards deliberate self-harm. The \\'Self-Harm Antipathy Scale\\

    Full Text Available The autism and schizophrenia spectra overlap to a large degree in the social and interpersonal domains. Similarly, abnormal excitatory glutamate and inhibitory γ-aminobutyric acid (GABA neurotransmitter concentrations have been reported for both spectra, with the interplay of these neurotransmitters important for cortical excitation to inhibition regulation. This study investigates whether these neurotransmitter abnormalities are specific to the shared symptomatology, and whether the degree of abnormality increases with increasing symptom severity. Hence, the relationship between the glutamate/GABA ratio and autism and schizophrenia spectrum traits in an unmedicated, subclinical population was investigated.A total of 37 adults (19 female, 18 male aged 18-38 years completed the Autism Spectrum Quotient (AQ and Schizotypal Personality Questionnaire (SPQ, and participated in the resting state proton magnetic resonance spectroscopy study in which sequences specific for quantification of glutamate and GABA+ concentration were applied to a right and left superior temporal voxel.There were significant, moderate, positive relationships between right superior temporal glutamate/GABA+ ratio and AQ, SPQ and AQ+SPQ total scores (p<0.05, SPQ subscales Social Anxiety, No Close Friend, Constricted Affect, Odd Behaviour, Odd Speech, Ideas of Reference and Suspiciousness, and AQ subscales Social Skills, Communication and Attention Switching (p<0.05; increased glutamate/GABA+ coinciding with higher scores on these subscales. Only the relationships between glutamate/GABA+ ratio and Social Anxiety, Constricted Affect, Social Skills and Communication survived multiple comparison correction (p< 0.004.

    Attempts to predict suicidal behavior within high-risk populations have so far shown insufficient accuracy. Although several psychosocial and clinical features have been consistently associated with suicide attempts, investigations of latent structure in well-characterized populations of suicide attempters are lacking. We analyzed a sample of 1,009 hospitalized suicide attempters that were recruited between 1999 and 2012. Eleven clinically relevant items related to the characteristics of suicidal behavior were submitted to a Hierarchical Ascendant Classification. Phenotypic profiles were compared between the resulting clusters. A decisional tree was constructed to facilitate the differentiation of individuals classified within the first 2 clusters. Most individuals were included in a cluster characterized by less lethal means and planning ("impulse-ambivalent"). A second cluster featured more carefully planned attempts ("well-planned"), more alcohol or drug use before the attempt, and more precautions to avoid interruptions. Finally, a small, third cluster included individuals reporting more attempts ("frequent"), more often serious or violent attempts, and an earlier age at first attempt. Differences across clusters by demographic and clinical characteristics were also found, particularly with the third cluster whose participants had experienced high levels of childhood abuse. Cluster analysis consistently supported 3 distinct clusters of individuals with specific features in their suicidal behaviors and phenotypic profiles that could help clinicians to better focus prevention strategies. © Copyright 2016 Physicians Postgraduate Press, Inc.

    This research tests the possibility that the reasonable woman as compared to the reasonable person test of hostile work environment sexual harassment interacts with hostile and benevolent sexist beliefs and under some conditions triggers protectionist attitudes toward women who complain of sexual harassment. We administered to a sample of undergraduates the ambivalent sexism inventory along with the fact patterns in two harassment cases and asked them to make legally relevant decisions under either the reasonable woman or person standard. We found that those high in hostile sexism, and women, found more evidence of harassment. However, those high in benevolent sexism did not exhibit the hostile sexism effects. Although men were less sensitive to the reasonable woman standard than women, under some conditions the reasonable woman standard enabled both genders to find greater evidence of harassment. The results are discussed from the perspectives of law and psychology.

    Objective: No research has been conducted on facial emotional recognition on patients with borderline personality disorder (BPD) and schizotypal personality disorder (SPD). The present study aimed at comparing facial emotion recognition in these patients with the general population. The neurocognitive processing of emotions can show the pathologic style of these 2 disorders. Method: Twenty BPD patients, 16 SPD patients, and 20 healthy individuals were selected by available sampling method. Structural Clinical Interview for Axis II, Millon Personality Inventory, Beck Depression Inventory and Facial Emotional Recognition Test was were conducted for all participants. Discussion: The results of one way ANOVA and Scheffe's post hoc test analysis revealed significant differences in neuropsychology assessment of facial emotional recognition between BPD and SPD patients with normal group (p = 0/001). A significant difference was found in emotion recognition of fear between the 2 groups of BPD and normal population (p = 0/008). A significant difference was observed between SPD patients and control group in emotion recognition of wonder (p = 0/04(. The obtained results indicated a deficit in negative emotion recognition, especially disgust emotion, thus, it can be concluded that these patients have the same neurocognitive profile in the emotion domain.

    Parenting can be a stressful experience particularly for people with mental health problems or people who experienced abuse or attachment difficulties in their own childhoods. This study examined the relationships between earlier trauma, attachment, parenting and schizotypy in a non-clinical sample, with the specific hypothesis that parenting stress and competence would mediate any association between trauma, attachment and schizotypy. One hundred and thirty-four first time parents with a child under 12 months old completed the following questionnaires online: the Experiences of Close Relationships Scale - Short Form (ECR-S), the Schizotypal Personality Questionnaire - Brief, Revised (SPQ-BR) the Parenting Stress Scale, the Parenting Sense of Competence Scale (PSOC) and the Adverse Childhood Experiences (ACE) Questionnaire. Parenting stress mediated the association between attachment and schizotypy, though parenting competence did not have a significant effect as a mediator in a parallel model. Childhood trauma was associated with attachment and schizotypy but did not correlate with the parenting variables. The study utilised a cross-sectional design and self-report measures which limits the ability to make causal inferences from the results. However, findings warrant replication in clinical samples with psychosis. The study adds to the understanding of what may exacerbate schizotypal symptoms in the first 12 months postpartum as parental attachment insecurity and parental stress together predicted elevated self-reported experiences of schizotypal symptoms.

  18. Characters and ambivalence in Luke: An emic reading of Luke’s gospel, focusing on the Jewish peasantry

    Full Text Available The Jewish peasantry as a character group in the Gospel of Luke has, thus far, not really attracted much attention in Lukan scholarship. In cases where it has been studied, scholars have often treated ὄχλος [crowd] and λαὸς [people] as synonymous characters. But the question of Jesus’ identity, as depicted in the New Testament, was crucial to the early church and it is this exact question that animates the relationship between Jesus and the various ‘systems’ functioning as part of Luke’s Gospel. From an etic viewpoint, the context of Luke’s Gospel indicates that Jesus’ leadership was characterised by conflict, opposition and rejection. Therefore, this article attempted, through an emic reading of Luke, to differentiate between (and describe the role played by each of these character groups in Luke’s narrative, focusing on the relationship between Jesus and the Jewish peasantry – with special reference to the ambivalent attitude of the latter. It was argued that each Lukan character group has to be read and understood in terms of their attitude, as well as in the broader context of Luke’s intention with their inclusion and specific description. Therefore the various terminologies used when referring to the Jewish peasantry were also discussed; for any analysis of a biblical character group should begin with a reading of the Greek text, because working only with translations can lead to a misappropriation of the text. In order to attain the goals as set out above, this study used a character group which seemed ambivalent and hypocritical in their attitude to analyse Jesus’ leadership approach.

    Autistic personality traits (APT) and schizotypal personality traits (SPT) are associated with depression. However, mediating factors within these relationships have not yet been explored. Thus, the focus of the current study was to examine the effects of childhood neglect on the relationship between APT/SPT and depression. This cross-sectional study was conducted on first-year students (N = 2469) at Hunan University of Chinese Medicine and Hengyang Normal College (Changsha, China). Participants completed surveys on APT, SPT, childhood neglect, abuse and depression. Through correlational analyses, APT and SPT traits were positively correlated with childhood neglect and depression (p childhood maltreatment, emotional neglect (β = 0.112, p Childhood neglect did not account for the relationships between APT/SPT and depression. Further analysis found that childhood neglect mediated the relationship between SPT and depression but not APT and depression. Among types of childhood maltreatment, neglect was the strongest predicting factor for depression. Neglect did not account for the relationship between APT/SPT and depression but was a strong mediating factor between SPT and depression.

    Schizotypal personality disorder (SPD) is a schizophrenia-spectrum disorder characterized by odd or bizarre behavior, strange speech, magical thinking, unusual perceptual experiences, and social anhedonia. Schizophrenia proper has been associated with anomalies in dopaminergic neurotransmission and deficits in neurophysiological markers of self-monitoring, such as low amplitude in cognitive event-related brain potentials (ERPs) like the error-related negativity (ERN), and the error positivity (Pe). These components occur after performance errors, rely on adequate fronto-striatal function, and are sensitive to dopaminergic modulation. Here we postulated that analogous to observations in schizophrenia, SPD individuals would show deficits in self-monitoring, as measured by the ERN and the Pe. We also assessed the capacity of dopaminergic antagonists to reverse these postulated deficits. We recorded the electroencephalogram (EEG) from 9 SPD individuals and 12 healthy controls in two separate experimental sessions while they performed the Eriksen Flanker Task, a classical task recruiting behavioral monitoring. Participants received a placebo or 1 mg risperidone according to a double-blind randomized design. After placebo, SPD individuals showed slower reaction times to hits, longer correction times following errors and reduced ERN and Pe amplitudes. While risperidone impaired performance and decreased ERN and Pe in the control group, it led to behavioral improvements and ERN amplitude increases in the SPD individuals. These results indicate that SPD individuals show deficits in self-monitoring analogous to those in schizophrenia. These deficits can be evidenced by neurophysiological measures, suggest a dopaminergic imbalance, and can be reverted by dopaminergic antagonists.

Nosso artigo pretende descrever essa transformação e defender uma tese específica. O mundo moderno pós-Ford apresenta dois novos aspectos quando comparado ao que fora descrito na análise funcionalista tradicional: por um lado, as tensões inerentes à natureza ambivalente da flexibilidade são vistas hoje como questões mais pessoais; por outro, a ambivalência não é mais encarada como puramente disfuncional, mas tem um aspecto positivo. À luz desse novo quadro de referência, apresentaremos inicialmente o cenário dos vários debates sobre flexibilidade na França, e mostraremos, em seguida, as relações entre flexibilidade e ambivalência sociológica, antes de apresentarmos os dados empíricos que sustentam nossa tese.Both the situation of employment in France and the frameworks used to analyse flexibility have evolved considerably over the last twenty years. The paper aims to describe this transformation and defend a particular thesis. Our post-Ford modern world has two new aspects when compared with the traditional functionalist analysis: on the one hand, the tensions inherent in the ambivalent nature of flexibility are today seen as more personal issues, and on the other, ambivalence is no longer seen as purely dysfunctional, but to have a possible positive aspect. Given this new framework, the paper first presents the background to the various debates on flexibility in France, and then shows the links between flexibility and sociological ambivalence before presenting empirical data in support of the thesis.

    The current study examined the effects of framing in promotional health messages on intention to vaccinate against seasonal influenza virus. The findings of an experimental study (N = 86) indicated that exposure to both benefits and side effects of vaccination (gain-framed with risk disclosure message) led to lower intention to receive the flu vaccine. This relationship was mediated by both perceived vaccine efficacy and felt ambivalence in a serial order, revealing the underlying psychological mechanisms important for understanding health-related behaviors. Theoretical implications of constructing sub-framed messages are discussed and the concept of second-order framing is introduced.

    Thought-action fusion (TAF) is a cognitive bias that has been linked to obsessive-compulsive disorder (OCD). Preliminary evidence suggests schizotypal traits may be associated with some types of OCD obsessions but not others. We examined the relationship between each of the two major types of TAF (i.e., likelihood and moral), schizotypal traits, and OCD symptoms in 969 nonclinical undergraduate students. We hypothesized that likelihood TAF would be associated with schizotypal traits; whereas moral TAF would not. Consistent with prediction, schizotypal-magical thinking was significantly associated with likelihood TAF even after controlling for the effects of OCD symptoms, general anxiety, and depression. Moreover, the relationship between likelihood TAF and OCD symptoms was significantly attenuated after controlling for schizotypal traits. In contrast, moral TAF demonstrated negligible association with OCD symptoms, depression, or schizotypal traits. These findings provide preliminary support for the linkage between likelihood TAF and schizotypal traits.

  8. The Social Meaning of Inherited Financial Assets. Moral Ambivalences of Intergenerational Transfers

    2013-11-01

    Full Text Available What do inherited financial assets signify to heirs and testators and how does this shape their conduct? Based on grounded theory methodology and twenty open, thematically structured interviews with US heirs, future heirs and testators, this article explicates a theoretical account that proposes a moral ambivalence as the core category to understand the social meaning of inherited financial assets. In particular, the analysis reveals that the social meaning of inherited assets is a contingent, individual compromise between seeing inherited assets as unachieved wealth and seeing them as family means of support. Being the lifetime achievement of another person, inheritances are, on the one hand, morally dubious and thus difficult to appropriate. Yet in terms of family solidarity, inheritances are "family money," which is used when need arises. Taken from this angle, inheriting is not the transfer of one individual's privately held property to another person, but rather the succession of the social status as support-giver along with the resources that belong to this status to the family's next generation. Heirs need to find a personal compromise between these poles, which always leaves room for interpretation. http://nbn-resolving.de/urn:nbn:de:0114-fqs1401131

    Full Text Available Schizotypal personality disorder (SPD is considered one of the classic disconnection syndromes. However, the specific cortical disconnectivity pattern has not been fully investigated. In this study, we aimed to explore significant alterations in whole-cortex structural connectivity in SPD individuals (SPDs by combining the techniques of brain surface morphometry and white matter (WM tractography. Diffusion and structural MR data were collected from twenty subjects with SPD (all males; age, 19.7 ± 0.9 yrs and eighteen healthy controls (all males; age, 20.3 ± 1.0 yrs. To measure the structural connectivity for a given unit area of the cortex, the fiber connectivity density (FiCD value was proposed and calculated as the sum of the fractional anisotropy of all the fibers connecting to that unit area in tractography. Then, the resultant whole-cortex FiCD maps were compared in a vertex-wise manner between SPDs and controls. Compared with normal controls, SPDs showed significantly decreased FiCD in the rostral middle frontal gyrus (crossing BA9 and BA10 and significantly increased FiCD in the anterior part of the fusiform/inferior temporal cortex (P < 0.05, Monte Carlo simulation corrected. Moreover, the gray matter volume extracted from the left rostral middle frontal cluster was observed to be significantly greater in the SPD group (P = 0.02. Overall, this study identifies a decrease in connectivity in the left middle frontal cortex as a key neural deficit at the whole-cortex level in SPD, thus providing insight into its neuropathological basis.

    2012-04-01

    Full Text Available The Maysles brothers’ 1975 documentary, Grey Gardens, portrays the lives of Edith Bouvier Beale and her daughter, Edith, known as Little Edie, the aunt and first cousin, respectively, of Jacqueline Bouvier Kennedy Onassis. The mother and daughter live together in their East Hampton house that is literally falling apart. As their identical names imply, the Beales share a symbiotic relationship which is reflected in every aspect of their life. I argue that Grey Gardens calls for Julia Kristeva’s insistence on abjection as a crucial struggle with “spatial ambivalence (inside/outside uncertainty” and an attempt to mark out a space in the undifferentiated field of the mother-child symbiosis. In Powers of Horror, Kristeva (1982 states, “abjection preserves what existed in the archaism of pre-objectal relationship” (p. 10. Grey Gardens portrays the topology of the mother-child dyad, which pertains to a particular spatio-temporality: where this primordial relationship is concerned, object and subject crumble, and the distinction between past and present is irrelevant.

    Full Text Available Both religious modernism and religious fundamentalism appeared as problems in academic and theological literature at the beginning of the 20th century. They came about as the result of the dynamic development of modernistic ideology in Russia, the United States, Western Europe and the Islamic world. Today, the concepts of religious modernism and religious fundamentalism are widely used to describe religious processes and phenomena which are the result of interaction between religion (as a dynamic spiritual and social subsystem and society - as a social system experiencing evolution. The concept of religious modernism is traditionally associated with religious renewal, the contemporary world, and innovation. Fundamentalism, on the contrary, is an ideological commitment to the “roots and origins” of religion. Under the aegis of fundamentalism, any religious idea, value or concept has a right to exist. Religious Studies, during the course of time and the production of ever new material, encountered a serious theoretic-methodological problem: How can various religious movements and religious traditions be organized into groups since some of them combine elements of religious modernism and of religious fundamentalism? Already at the end of the nineteen-eighties, the well-established view defining “fundamentalism-modernism” as contrary positions had to be rethought. Studies dating from the nineteen-nineties and the beginning of the new millennium concentrated on noting the social origins and the political character of these phenomena. They demonstrated that neither fundamentalism nor modernism present the whole picture. The lines dividing them are so blurred, that they become confl uent. Consequently, the author concludes that religious fundamentalism and religious modernism are ambivalent phenomena, which can, on occasion, interact with each other.

  12. How to tell a happy from an unhappy schizotype: personality factors and mental health outcomes in individuals with psychotic experiences

    Full Text Available Objective: It is unclear why some individuals reporting psychotic experiences have balanced lives while others go on to develop mental health problems. The objective of this study was to test if the personality traits of harm avoidance, self-directedness, and self-transcendence can be used as criteria to differentiate healthy from unhealthy schizotypal individuals. Methods: We interviewed 115 participants who reported a high frequency of psychotic experiences. The instruments used were the Temperament and Character Inventory (140, Structured Clinical Interview for DSM-IV, and the Oxford-Liverpool Inventory of Feelings and Experiences. Results: Harm avoidance predicted cognitive disorganization (β = 0.319; t = 2.94, while novelty seeking predicted bipolar disorder (β = 0.136, Exp [β] = 1.146 and impulsive non-conformity (β = 0.322; t = 3.55. Self-directedness predicted an overall decrease in schizotypy, most of all in cognitive disorganization (β = -0.356; t = -2.95 and in impulsive non-conformity (β = -0.313; t = -2.83. Finally, self-transcendence predicted unusual experiences (β = 0.256; t = 2.32. Conclusion: Personality features are important criteria to distinguish between pathology and mental health in individuals presenting high levels of anomalous experiences (AEs. While self-directedness is a protective factor, both harm avoidance and novelty seeking were predictors of negative mental health outcomes. We suggest that the impact of AEs on mental health is moderated by personality factors.

    Full Text Available Different from that in the second half of the eighteenth century, travel literature today is a paradise for women authorship. Under the cosmopolitan worldview, women travellers compete with their male counterparts observing and reporting their adventure around the world. Mary Gray, an Irish author who now lives in New Zealand, for example, presents her experience traveling in Indonesia in the reform era. Showing some indication of East- West relation, the work is considered as containing postcolonial discourses offeringalternative answers to the world problem related to new imperial phenomena. Using the postcolonial approach and Pratt‘s theory in travel writing, this research was conducted to identify the traveler‘s strategy called the ‗seeing woman‘ the positions she tries to achieve in her object representation.The result shows some traces of ambivalence within the new imperial andcosmopolitan imperatives.

Los resultados permitieron el entendimiento de que la ambivalencia con respecto a la ligadura de trompas es un fenómeno que, sujeto a múltiples determinaciones, implica una gran parte de la subjetividad de la mujer, lo que hace compleja su interpretación.Exploratory research, which used the database of a research involving women undergoing tubal ligation, to determine, more accurately, the frequency of ambivalent women and analyze the statistical distribution of these women according to the selected research and how they had originally classified themselves in regard to the procedure (totally or moderately satisfied, ambivalent, totally or moderately regretful. The assumption of the study was that, making up a more accurate assessment of the answers to several of the issues that were asked to them, the number of ambivalent women could be higher than previously disclosed. This assumption was confirmed, being noted a significant increase of women who both had reasons for satisfaction as to regret in relation to tubal ligation (ambivalent women. The results allowed the understanding that the ambivalence regarding tubal ligation is a phenomenon that, subject to multiple determinations, involves a very large portion of the subjectivity of women, making its interpretation a very complex one.

    Background A defining feature of personality disorder (PD) is an enduring pattern of inner experience and behavior that is stable over time. Follow-up and follow-along studies have shown considerable diagnostic instability of PDs, however, even over short intervals. What, then, about personality disorder is stable ? The purpose of this study was to determine the stability of impairment in psychosocial functioning in patients with four different PDs, in contrast to patients with major depressive disorder (MDD) and no PD, prospectively over a 2-year period. Method Six hundred treatment-seeking or treated patients were recruited primarily from clinical services in four metropolitan areas of the Northeastern USA. Patients were assigned to one of five diagnostic groups: schizotypal (STPD) (n=81), borderline (BPD) (n=155), avoidant (AVPD) (n=137), or obsessive–compulsive (OCPD) (n=142) personality disorders or MDD and no PD (n=85), based on the results of semi-structured interview assessments and self-report measures. Impairment in psychosocial functioning was measured using the Longitudinal Interval Follow-up Evaluation (LIFE) at baseline and at three follow-up assessments. Results Significant improvement in psychosocial functioning occurred in only three of seven domains of functioning and was largely the result of improvements in the MDD and no PD group. Patients with BPD or OCPD showed no improvement in functioning overall, but patients with BPD who experienced change in personality psychopathology showed some improvement in functioning. Impairment in social relationships appeared most stable in patients with PDs. Conclusion Impairment in functioning, especially social functioning, may be an enduring component of personality disorder. PMID:15841879

    This study was performed with an aim to understand the conditions causing the ambivalence of the person with bipolar affective disorder (BAD) regarding following the drug treatment. A qualitative approach was used, with the Grounded Theory as the methodology framework, under the light of Symbolic Interactionism. Participants were 14 individuals with BAD who were being followed at an Outpatient Clinic for Mood Disorders of a university hospital and 14 relatives they indicated. Interviews and observation were the main forms of obtaining data. Results revealed three categories that described the referred causal conditions: experiencing the crises of the disorder; needing the drug; and living with the side effects of the drugs. It was found that there is a need to change the attitude of some health professionals from blaming the patient for interrupting the treatment to one of listening, valuing their symbolic and affective universe as well as the partnership in the treatment.

  17. "Doctor, are you trying to kill me?": ambivalence about the patient package insert for estrogen.

    Watkins, Elizabeth Siegel

    2002-01-01

    In 1976, the U.S. Food and Drug Administration proposed new requirements for patient labeling for estrogens prescribed for menopausal and postmenopausal women. This paper explores the variety of responses to this proposal from women and their husbands, feminist and consumer activists, physicians, pharmacists, and pharmaceutical manufacturers, as represented in letters written to the FDA. The drug industry and the medical profession opposed patient labeling on the grounds of cost and a resentment of governmental intrusion. Feminists and consumer advocates were in favor of the idea, but the response from current estrogen users was mixed: most women wished to be better informed, but many expressed concern that estrogen would be removed from the market. This ambivalence suggests unresolved tensions regarding conceptions of female aging, the medical management of menopause and aging, informed consent in medicine, and governmental regulation of medical practice. The debate thus represents an important moment in the history of women's health care.

    Its focus on snow-dependent activities makes Alpine winter tourism especially sensitive to climate change. Stakeholder risk perceptions are a key factor in adaptation to climate change because they fundamentally drive or constrain stakeholder action. This paper examines climate change perceptions of winter tourism stakeholders in Tyrol (Austria). Using a qualitative approach, expert interviews were conducted. Four opinion categories reflecting different attitudes toward climate change issues were identified: convinced planners, annoyed deniers, ambivalent optimists, convinced wait-and-seers. Although the findings generally indicate a growing awareness of climate change, this awareness is mainly limited to perceiving the issue as a global phenomenon. Awareness of regional and branch-specific consequences of climate change that lead to a demand for action could not be identified. Current technical strategies, like snowmaking, are not primarily climate-induced. At present, coping with climate change is not a priority for risk management. The findings point out the importance of gaining and transferring knowledge of regional and branch-specific consequences of climate change in order to induce action at the destination level.

  20. Diagnostic ambivalence: psychiatric workarounds and the Diagnostic and Statistical Manual of Mental Disorders.

    2010-03-01

    In 1980 the American Psychiatric Association (APA), faced with increased professional competition, revised the Diagnostic and Statistical Manual of Mental Disorders (DSM). Psychiatric expertise was redefined along a biomedical model via a standardised nosology. While they were an integral part of capturing professional authority, the revisions demystified psychiatric expertise, leaving psychiatrists vulnerable to infringements upon their autonomy by institutions adopting the DSM literally. This research explores the tensions surrounding standardisation in psychiatry. Drawing on in-depth interviews with psychiatrists, I explore the 'sociological ambivalence' psychiatrists feel towards the DSM, which arises from the tension between the desire for autonomy in practice and the professional goal of legitimacy within the system of mental health professions. To carve a space for autonomy for their practice, psychiatrists develop 'workarounds' that undermine the DSM in practice. These workarounds include employing alternative diagnostic typologies, fudging the numbers (or codes) on official paperwork and negotiating diagnoses with patients. In creating opportunities for patient input and resistance to fixed diagnoses, the varied use of the DSM raises fundamental questions for psychiatrists about the role of the biomedical model of mental illness, especially its particular manifestation in the DSM.

    2012-01-01

    This article uses the contributions of ergonomics to understand the work performed by hotel managers. The concern to understand the job of managers is something new in the ergonomics and few studies address this issue, especially in what concerns the work of hotel managers and its aspects of performance and health, which is the focus of this article. Through a literature review on the subject, it is sought to understand the managers' work activity, the impacts on their health and their organizational performance, as managers take an ambivalent position in organizations, since they have to deal directly with the demands of upper and lower hierarchies in a context of high competition, organizational changes and user requirements. It is then inferred there is a risk of increased work density for managers, bringing negative consequences to their health and organizational performance. This phenomenon, still poorly covered by ergonomics, contributes to a certain invisibility of the manager's work in society as a whole, when the manager may suffer from health problems, which are also common in certain populations of workers who do not take the managerial function.

    Full Text Available In this article I examine the autobiographical texts of two Baltic German women, Natalie von Maydell (1878-1970 and Agnes von Baranow (1877-1968 and analyse their depiction of two breakthrough events in Estonian history: the establishment of the Republic of Estonia and the compulsory relocation of the Baltic Germans. Natalie von Maydell’s memoir, “Ein reiches Leben” is an unpublished manuscript in the family’s possession; Agnes von Baranow’s reminiscences titled Mein Baltenland were published soon after the resettlement in 1941. The analysis has been informed by postcolonial theory, in particular Homi K. Bhabha’s discussion of the master. In her reminiscences, Natalie von Maydell describes her return to the Paasvere Manor at the end of the winter of 1919. During the winter of 1918-1919 the manor had been overtaken by the Bolsheviks, who had vandalized it; Maydell portrays the outward changes in the manor house, how their home did not look homey any longer. In addition to the immediate damage to the building, lost or damaged household items and the violation of a secure home atmosphere, the writer describes the more significant change in the servants’ attitudes: while the damage and pillage could be rectified, it was impossible to control the people again. The circumstances had changed Estonian attitudes toward Germans, and to Maydell it was a painful and alienating experience. Home had become “unhomely.” At the same time, Maydell claims that the Estonians came to talk to her husband secretly, at night. With this sentence she smoothes over the new situation: the attributes of an old, paternalistic system are citations of earlier better times. Life that previously had clear boundaries was now blurred and confused: from one perspective it seemed the same but the next moment she would be reminded again in one way or the other. It is also important to note that the fragility and ambivalence in the Baltic German position was not

    Provoked vestibulodynia (PVD) is a highly prevalent and taxing female genital pain condition. Despite the intimate nature of this pain and the fact that affective factors such as anxiety have been shown to modulate its manifestations, no study has yet explored the emotional regulation of couples in which the woman suffers from PVD. Ambivalence over emotional expression (AEE) is an emotional regulation variable that quantifies the extent to which a person is comfortable with the way she or he expresses emotions. We examined whether the dyadic AEE of couples in which the woman suffers from PVD was differentially associated with women's pain and couples' psychological, sexual, and relational functioning. Couples (N = 254), in which the woman suffered from PVD, completed the AEE questionnaire. A couple typology of dyadic AEE was created. Dependent measures for both members of the couple were the global measure of sexual satisfaction scale, the Beck depression inventory II, and the revised dyadic adjustment scale. The female sexual function index and the sexual history form were used to assess the sexual function of women and men, respectively. Women also completed the pain rating index of the McGill pain questionnaire. Couples, in which both partners were considered low on AEE, had the highest scores on sexual satisfaction (P = 0.02) and function (P sexual, and relational outcomes. Results indicate that emotional regulation may be important to consider in the assessment and treatment of couples coping with PVD. © 2014 International Society for Sexual Medicine.

  4. Ambivalence, equivocation and the politics of experimental knowledge: a transdisciplinary neuroscience encounter.

    This article is about a transdisciplinary project between the social, human and life sciences, and the felt experiences of the researchers involved. 'Transdisciplinary' and 'interdisciplinary' research-modes have been the subject of much attention lately--especially as they cross boundaries between the social/humanistic and natural sciences. However, there has been less attention, from within science and technology studies, to what it is actually like to participate in such a research-space. This article contributes to that literature through an empirical reflection on the progress of one collaborative and transdisciplinary project: a novel experiment in neuroscientific lie detection, entangling science and technology studies, literary studies, sociology, anthropology, clinical psychology and cognitive neuroscience. Its central argument is twofold: (1) that, in addition to ideal-type tropes of transdisciplinary conciliation or integration, such projects may also be organized around some more subterranean logics of ambivalence, reserve and critique; (2) that an account of the mundane ressentiment of collaboration allows for a more careful attention to the awkward forms of 'experimental politics' that may flow through, and indeed propel, collaborative work more broadly. Building on these claims, the article concludes with a suggestion that such subterranean logics may be indissociable from some forms of collaboration, and it proposes an ethic of 'equivocal speech' as a way to live with and through these kinds of transdisciplinary experiences.

  5. Critical Nexus or Pluralist Discipline? Institutional Ambivalence and the Future of Canadian Sociology.

    2015-08-01

    While some scholars believe in a transdisciplinary future for the social sciences and humanities, we argue that sociology would do well to maintain its disciplinary borders, while celebrating the plurality of its intellectual, social, and political content. Although a pluralist position can threaten disciplinary coherence and increase fragmentation, we argue the counterbalance ought to be convergence around shared institutional norms of knowledge production. Establishing these norms is not easy, since there is a great deal of institutional ambivalence at play in the field of sociology. As such, sociology is pushed and pulled between two poles of at least four major continuums of knowledge production, which include the following: (1) interdisciplinary versus discipline-based research; (2) political versus analytical scholarship; (3) professional versus public/policy sociology; and (4) local/national versus global audiences. Since both sides of these ideal-typical continuums contain their own pathologies, we propose adopting a balanced position to correct for the shortcomings of each. Rather than imposing one philosophical or theoretical paradigm for the field, we suggest that embracing the "chaos" of our diverse forms of knowledge and centralizing and integrating findings will serve to strengthen our collective efforts in the long term. © 2015 Canadian Sociological Association/La Société canadienne de sociologie.

    Full Text Available

    This essay examines African American novelist Pauline Hopkins’s deployment of the trope of respectable domesticity to contest black disenfranchisement in the context of African Americans’ ambivalent relationship to late-nineteenth-century US imperial expansion in the Asia Pacific. This essay analyzes Contending Forces (1900 in relation to two crucial yet underexplored contexts: first, Hopkins’s commentaries on international race relations; second, African American intellectuals’ commentaries on US imperial ventures in the Asia Pacific and on Chinese immigration in the Colored American Magazine, where Hopkins’s fictional works were serialized. Situated within these contexts of comparative racialization, Hopkins’s works offer critical responses to the masculine nationalist representations of black–Asian relations, illuminating the divisive effects of nationalist identification on differentially racialized subjects, the uneven effects of marriage on the black community, and this institution’s structural ties to imperialism and to the color-based class hierarchy within the imagined black community—all of which call for radical reimagining of race relations beyond the nation form.

  7. Adult Fear and Control: Ambivalence and Duality in Clive Barker’s The Thief of Always

    2016-02-01

    Full Text Available This article considers the relationship between the text and accompanying illustrations in Clive Barker’s children’s novel The Thief of Always: A Fable. This tale of abduction was published in the social background of fear around the child predator of the early 1990s and incorporates ideas of monstrous villainy, loss of childhood innocence, and insatiable desires. As a fable, Thief is a cautionary tale that not only teaches that childhood years are precious and are not to be wished away or squandered in idle leisure, but also of the dangers that some adults pose to children. Problematically, an honest and frank discussion of adult sexual desires toward children would despoil the very innocence that is trying to be protected; thus, a lesson such as this must be sublimated within the story. Yet, it is the illustrations, and more specifically the way in which the illustrations corroborate and contradict the plot of this story that reveals an underlying ambivalence toward the figure of the child and an echoing duality present in both the child and the child predator.

    2012-11-01

    The authors present an integrative account of how attachment insecurities relate to sexism. Two studies showed that attachment avoidance predisposes men to endorse hostile but to reject benevolent sexism (BS), whereas attachment anxiety predisposes men toward ambivalent (both hostile and benevolent) sexism. The authors also tested predicted mediators, finding that men's social dominance orientation (a competitive intergroup ideology) mediated the avoidance to hostile sexism link. In addition, romanticism (an idealized interpersonal ideology) mediated attachment insecurity to BS links: (a) Avoidant men tended to reject romanticism (i.e., were cynical about romance) and, in turn, were likely to reject BS, whereas (b) anxious men tended to endorse romanticism (i.e., were idealistic about romance) and, in turn, likely to endorse BS. The authors conclude that men's sexism stems in part from dispositional attachment working models, both directly and through the interpersonal and intergroup ideologies they generate.

    Shanghai was considered to be a "capital of opium" in modern China, hence the history of opium in the city has received significant attention. In the Shanghai International Settlement, where Chinese and foreigners lived as neighbours, drugs were considered by the administration as both "trouble maker", and important financial resource. This paper explores how the Shanghai Municipal Council (SMC), the most senior governing body in the settlement, used its position to maximize political and economic profit from the trade and consumption of opium. The paper is based on documentary analysis of records of the SMC board meetings and other related material stored at Shanghai Municipal Archives. Interpretive approaches were used to analyze the shifting SMC strategies on opium consumption, the competing power relations and the way they were negotiated between actors with a stake in the region, including semi-colonialism and world systems analysis. With the dual purpose of preventing damage and enhancing municipal management, the SMC introduced a licensing system permitting the consumption and trade of drugs. However, the anti-opium policies of the late Qing government and the Anglo-Chinese 10 Year Agreement meant SMC had to shut down opium "houses" (opium dens) and "shops" (for the sale of opium to be consumed off the premises). Over almost a decade, the SMC shifted emphasis from political regulation of a social, recreational practice to maximizing financial benefit. In the process, SMC made full use of the opportunities it gained from a period of ambivalent Chinese and British power relations and local community rule. Copyright © 2016 Elsevier B.V.

Il fait l’hypothèse que ces pratiques alimentaires doivent être observées et s’apprécier en fonction des différents repas et moments alimentaires: petit-déjeuner, déjeuner, nourritures de rue, dîner conjugal, repas dans la belle famille. Ces situations sont riches d’ambivalences : attachement aux habitudes mais aussi passage du dégoût au goût ou bien de la méfiance à la curiosité, double appréciation pour la nourriture dont la présentation n’est pas estimée de la même façon que les produits eux-mêmes, efforts pour accepter les manières de table dans le cadre d’un rapport de force social et/ou affectif, enfin ‘‘oubli’’ de la question alimentaire au profit du lien social qu’il produit.From an investigation made in urban zones with nine male and female French people having migrated to Taiwan and married with Taiwaneses, the author studies the issue of food tensions in situation of mixed couples. He presents the hypothesis that these tensions vary according to food grips: breakfast, lunch, street foods, conjugal dinner, meals with allies. Such food tensions provoke varied practices and judgments: attachment to habits but also the passage of disgust to appreciation, distrust regarding curiosity, double appreciation for food displayed which is not esteemed in the same way as the products themselves, efforts to accept table manners within the framework of a social or emotional balance of power, finally ‘‘forgetting’’ the issue for the benefit of the social link which it produces.

  11. Brain electric correlates of strong belief in paranormal phenomena: intracerebral EEG source and regional Omega complexity analyses.

    The neurocognitive processes underlying the formation and maintenance of paranormal beliefs are important for understanding schizotypal ideation. Behavioral studies indicated that both schizotypal and paranormal ideation are based on an overreliance on the right hemisphere, whose coarse rather than focussed semantic processing may favor the emergence of 'loose' and 'uncommon' associations. To elucidate the electrophysiological basis of these behavioral observations, 35-channel resting EEG was recorded in pre-screened female strong believers and disbelievers during resting baseline. EEG data were subjected to FFT-Dipole-Approximation analysis, a reference-free frequency-domain dipole source modeling, and Regional (hemispheric) Omega Complexity analysis, a linear approach estimating the complexity of the trajectories of momentary EEG map series in state space. Compared to disbelievers, believers showed: more right-located sources of the beta2 band (18.5-21 Hz, excitatory activity); reduced interhemispheric differences in Omega complexity values; higher scores on the Magical Ideation scale; more general negative affect; and more hypnagogic-like reveries after a 4-min eyes-closed resting period. Thus, subjects differing in their declared paranormal belief displayed different active, cerebral neural populations during resting, task-free conditions. As hypothesized, believers showed relatively higher right hemispheric activation and reduced hemispheric asymmetry of functional complexity. These markers may constitute the neurophysiological basis for paranormal and schizotypal ideation.

    Rationale Schizotypal personality disorder (SPD) is associated with working memory (WM) impairments that are similar to those observed in schizophrenia. Imaging studies have suggested that schizophrenia is associated with alterations in dopamine D1-receptor availability in the prefrontal cortex (PFC) that may be related to the WM impairments that characterize this disorder. Objectives To characterize prefrontal D1-receptor availability and its relation to WM performance in SPD. Methods We used positron emission tomography (PET) and the radiotracer [11C]NNC112 with 18 unmedicated SPD and 21 healthy-control participants; as an index of D1-receptor availability, binding-potential (BP) measures (BPF, BPND, and BPP) were calculated for prefrontal and striatal subregions. To assess WM, SPD participants completed the 2-back and Paced Auditory Serial Addition Test (PASAT). Results There were no significant group differences in PFC BP. BPF and BPP in the medial PFC were significantly negatively related to PASAT performance (rs=-0.551, p=.022 and rs=-0.488, p=.047, respectively), but BP was not related to 2-back performance. Conclusions In contrast to what has been found in schizophrenia, SPD was not associated with significant prefrontal D1-receptor alterations. Similar to previous schizophrenia findings, however, higher prefrontal D1-receptor availability was associated with poorer WM performance (as measured by the PASAT) in SPD. These findings suggest that schizophrenia and SPD may share a common pathophysiological feature related to prefrontal dopamine functioning that contributes to WM dysfunction, but that in SPD, alterations in D1 may occur only in a subset of individuals and/or to an extent that is minor relative to what occurs in schizophrenia.

    Public health practitioners in Australian indigenous health work in a complex political environment. Public health training is limited in providing them with conceptual tools needed to unpack the postcolonial nexus of 'fourth-world' health. A workshop was designed by the authors to facilitate critical reflection on how the concepts of race and culture are used in constructions of indigenous ill-health. It was attended by researchers, students, clinicians and bureaucrats working in public health in northern Australia. A thematic analysis of the workshop minutes provided insight into public health practitioners' narratives of Indigenous ill-health. The major themes that emerged included tension between structure and agency and between sameness and difference, and ambivalence surrounding the 'helper' identity of public health practitioners. We suggest that these narratives can be understood as attempts to maintain the moral integrity of both Indigenous people and practitioners. This task is necessitated by the specter of cultural relativism intrinsic to contemporary liberal discourses of multiculturalism that attempt to reconcile the universal rights of the citizen with the special rights of minority groups. We argue that the concepts of self-determination and neocolonialism mark the spaces where universal and particular discourses overlap and clash. Practitioners who seek to escape neocolonialism must inhabit only the discursive space of public health congruent with self-determination, leaving them in a bind common to many postcolonial situations. They must relieve the ill-health of indigenous people without acting upon them; change them without declaring that change is required.

    Full Text Available A discriminação e a violência contra o gênero feminino associam-se a representações distorcidas da mulher. Este trabalho tem o objetivo de mensurar a existência de preconceitos nas manifestações dos estereótipos de gênero e sexismo ambivalente, em adolescentes masculinos de 12 a 16 anos. Em um estudo transversal, aplicaram-se três questionários (sociodemográfico, Gender stereotyping, Inventário do Sexismo Ambivalente a 787 estudantes de 11 escolas públicas. Nos resultados, detectou-se a presença de estereótipos de gênero. Houve diferença significante entre alunos de escolas estaduais e municipais e também nos alunos que estudavam em bairros de poder aquisitivo elevado em relação aos demais. O sexismo, também presente, apresentou-se significantemente mais benévolo que hostil. O escore para o componente benévolo variou conforme a escola cursada. O hostil não foi influenciado pelas variáveis estudadas. Os achados corroboram a existência de estereótipos de gênero e sexismo ambivalente nos adolescentes masculinos e a necessidade de desenvolvimento de ações e políticas para sua erradicação.Discrimination and violence against the female gender are associated with distorted representation of women.

  15. The Prince and the Hobby-Horse: Shakespeare and the Ambivalence of Early Modern Popular Culture

    Full Text Available The Shakespearean hobby-horse, mentioned emphatically in Hamlet, brings into focus a number of problems related to early modern popular culture. In the late sixteenth and early seventeenth centuries the word was characterised by semantic ambivalence, with simultaneously valid meanings of a breed of horse, a morris character, a foolish person, and a wanton woman. The overlapping of these meanings in different cultural discourses of the age (playtexts, emblem books, popular verse, pictures exemplifies the interaction of different productions of early modern popular culture, from social humiliating practices to festivals and public playhouses. This attests to a complex circulation of cultural memory regarding symbols of popular culture, paradoxically both ‘forgotten’ and ‘remembered’ as a basically oral-ritual culture was transformed into written forms. In this context, the Hamletian passage gains new overtones, while the different versions of the playtext (Q1 & 2: 1603, 1604, F: 1623 also offer insights into the changing attitudes regarding popular culture, as it became gradually commercialised and politicised in the following decades. Finally, Shakespeare’s The Winter’s Tale and Jonson’s Bartholomew Fair solidify a critical and sceptical attitude, which seems to have signalled the end of ‘Merry Old England’ on-stage and off-stage as well.

    Ongoing exposure to social stressors is widely believed to undermine the health of Hispanic immigrant families. The current work aims to explore and interpret expressions of familismo as a framework through which postimmigration experiences are interpreted and potentially given meaning. Qualitative data were obtained from 16 focus groups in California and Massachusetts (N = 93). Fifty-two percent of the participants identified as male and 59% primarily spoke Spanish. Analyses revealed 3 distinct forms of ambivalence specific to familismo among Hispanic adults from immigrant families. Give and take described experiences wherein immigrants turn their backs on family in the short term to realize a better long-term future for the family. Negative change explained family misfortunes that arise in the pursuit of a better future for the family and creates doubts about the vision that motivated migration. Forced shifts suggests the navigation of daily life necessitates the inversion or abandonment of culturally idealized family roles and responsibilities. Hispanic adults from immigrant families described several situations in which competing views of familismo likely influenced the interpretation of unanticipated stressors.

    The Adult Attachment Ratings (AAR) include 3 scales for anxious, ambivalent attachment (excessive dependency, interpersonal ambivalence, and compulsive care-giving), 3 for avoidant attachment (rigid self-control, defensive separation, and emotional detachment), and 1 for secure attachment. The scales include items (ranging from 6-16 in their original form) scored by raters using a 3-point format (0 = absent, 1 = present, and 2 = strongly present) and summed to produce a total score. Item response theory (IRT) analyses were conducted with data from 414 participants recruited from psychiatric outpatient, medical, and community settings to identify the most informative items from each scale. The IRT results allowed us to shorten the scales to 5-item versions that are more precise and easier to rate because of their brevity. In general, the effective range of measurement for the scales was 0 to +2 SDs for each of the attachment constructs; that is, from average to high levels of attachment problems. Evidence for convergent and discriminant validity of the scales was investigated by comparing them with the Experiences of Close Relationships-Revised (ECR-R) scale and the Kobak Attachment Q-sort. The best consensus among self-reports on the ECR-R, informant ratings on the ECR-R, and expert judgments on the Q-sort and the AAR emerged for anxious, ambivalent attachment. Given the good psychometric characteristics of the scale for secure attachment, however, this measure alone might provide a simple alternative to more elaborate procedures for some measurement purposes. Conversion tables are provided for the 7 scales to facilitate transformation from raw scores to IRT-calibrated (theta) scores.

  19. How semantic deficits in schizotypy help understand language and thought disorders in schizophrenia: a systematic and integrative review

    Hélio Anderson Tonelli

    2014-04-01

    Full Text Available Introduction: Disorders of thought are psychopathological phenomena commonly present in schizophrenia and seem to result from deficits of semantic processing. Schizotypal personality traits consist of tendencies to think and behave that are qualitatively similar to schizophrenia, with greater vulnerability to such disorder. This study reviewed the literature about semantic processing deficits in samples of individuals with schizotypal traits and discussed the impact of current knowledge upon the comprehension of schizophrenic thought disorders. Studies about the cognitive performance of healthy individuals with schizotypal traits help understand the semantic deficits underlying psychotic thought disorders with the advantage of avoiding confounding factors usually found in samples of individuals with schizophrenia, such as the use of antipsychotics and hospitalizations. Methods: A search for articles published in Portuguese or English within the last 10 years on the databases MEDLINE, Web of Science, PsycInfo, LILACS and Biological Abstracts was conducted, using the keywords semantic processing, schizotypy and schizotypal personality disorder. Results: The search retrieved 44 manuscripts, out of which 11 were firstly chosen. Seven manuscripts were additionally included after reading these papers. Conclusion: The great majority of the included studies showed that schizotypal subjects might exhibit semantic processing deficits. They help clarify about the interfaces between cognitive, neurophysiological and neurochemical mechanisms underlying not only thought disorders, but also healthy human mind's creativity.

  20. Functional near-infrared spectroscopy reveals altered hemispheric laterality in relation to schizotypy during verbal fluency task.

    Previous functional neuroimaging studies have demonstrated that patients with schizophrenia and those with schizotypal personality disorder (SPD) show reduced laterality, or relative right hemispheric dominance, during the performance of cognitive activation tasks; however, neuroimaging studies looking at non-clinical schizotypy have been few. We have recently reported that schizotypal traits at a non-clinical level are associated with right prefrontal dominance during a letter version of the verbal fluency task (VFT), but it is unknown whether such relationship between schizotypy and functional laterality would be observed across various cognitive tasks. Here we examined the relationships of schizotypal traits as measured by the Schizotypal Personality Questionnaire (SPQ) in healthy adults with hemispheric lateralization of prefrontal activation during letter and category VFTs, using near-infrared spectroscopy. Thirty-two participants were divided into high- (n=16) and low- (n=16) SPQ groups by the median split of the total SPQ score. The high-SPQ group, but not low-SPQ group, showed significantly right-greater-than-left asymmetry of prefrontal activation during letter VFT, whereas such pronounced hemispheric asymmetry in relation to schizotypy was not found during category VFT. These results indicate that non-clinical schizotypy is related to right prefrontal preference during the letter version of VFT in particular, suggesting that the association between schizotypal traits and functional laterality may vary depending on cognitive activation tasks.

    Despite an emerging literature characterizing the neuropsychological profiles of borderline, antisocial, and schizotypal personality disorders, relations between personality disorder traits and neurocognitive domains remain unknown. The authors examined associations among Millon Clinical Multiaxial Inventory-III personality disorder scales and eight neuropsychological domains in 161 patients referred for neuropsychological evaluation following closed head injury. Most personality disorder scales were associated with some decrement in cognitive function, particularly speeded processing, executive function, and language, while histrionic and narcissistic scales had positive relations with neuropsychological functioning. Results suggest that many personality disorder traits are related to neurocognitive function, particularly those functions subserved by frontal and temporal regions.

    Pharmacological enhancement of prefrontal D1 dopamine receptor function remains a promising therapeutic approach to ameliorate schizophrenia-spectrum working memory deficits, but has yet to be rigorously evaluated clinically. This proof-of-principle study sought to determine whether the active enantiomer of the selective and full D1 receptor agonist dihydrexidine (DAR-0100A) could attenuate working memory impairments in unmedicated patients with schizotypal personality disorder (SPD). We performed a randomized, double-blind, placebo-controlled trial of DAR-0100A (15 mg/150 ml of normal saline administered intravenously over 30 min) in medication-free patients with SPD (n=16) who met the criteria for cognitive impairment (ie, scoring below the 25th percentile on tests of working memory). We employed two measures of verbal working memory that are salient to schizophrenia-spectrum cognitive deficits, and that clinical data implicate as being associated with prefrontal D1 availability: (1) the Paced Auditory Serial Addition Test (PASAT); and (2) the N-back test (ratio of 2-back:0-back scores). Study procedures occurred over four consecutive days, with working memory testing on Days 1 and 4, and DAR-0100A/placebo administration on Days 2-4. Treatment with DAR-0100A was associated with significantly improved PASAT performance relative to placebo, with a very large effect size (Cohen's d=1.14). Performance on the N-back ratio was also significantly improved; however, this effect rested on both a non-significant enhancement and diminution of 2-back and 0-back performance, respectively; therefore interpretation of this finding is more complicated. DAR-0100A was generally well tolerated, with no serious medical or psychiatric adverse events; common side effects were mild to moderate and transient, consisting mainly of sedation, lightheadedness, tachycardia, and hypotension; however, we were able to minimize these effects, without altering the dose, with supportive

  6. The cost of ambivalence -- A look at the power scene in South Asia

    This paper looks at the impact of acute power shortage in South Asia, state initiatives that are less than firm and decisive and attempts to make some suggestions on the issues involved. The discussion would be of interest to planners in other developing countries as well as independent power producers looking for investment opportunities in the region. The South Asian Region consists of countries of the Indian Ocean rim. The region is important as 1/5th of all humanity lives here. Yet it generates only about 5% of all the electricity produced in the world. While in absolute terms the economy especially that of India is one of the largest in the world the per capita GDP is among the lowest. So is the per capita power generation that is around 250 kWh (compare with 12308 kWh in the US). The acute shortage of power in a state of high industrial growth for a region that is richly endowed with various sources of energy as well has a developed capital goods industry, leads to the question as to what has gone wrong? The process of planning and execution of power projects as well as the lack of will for solid action seems to be the culprit. The governments of the region have well understood that the states' resources are just not adequate to support the massive investments required in the power sector. IPPs therefore are being welcomed, but with a sense of ambivalence. Power purchase agreements with private developers have dragged on in a state of uncertainty for years. Important on the agenda is to reform the state owned and monopolistic power utilities. Reforms and privatization are being aimed at supply side improvements, transmission and distribution loss reduction, end use efficiency improvement and encouragement to captive power generation by the industry. Some of the issues that stand out as facilitators and impediments are discussed in this paper

    Full Text Available We report conceptual inventory results of a large-scale assessment project at a large university. We studied the introduction of materials and instructional methods informed by physics education research (PER (physics education research-informed materials into a department where most instruction has previously been traditional and a significant number of faculty are hesitant, ambivalent, or even resistant to the introduction of such reforms. Data were collected in all of the sections of both the large algebra- and calculus-based introductory courses for a number of years employing commonly used conceptual inventories. Results from a small PER-informed, inquiry-based, laboratory-based class are also reported. Results suggest that when PER-informed materials are introduced in the labs and recitations, independent of the lecture style, there is an increase in students’ conceptual inventory gains. There is also an increase in the results on conceptual inventories if PER-informed instruction is used in the lecture. The highest conceptual inventory gains were achieved by the combination of PER-informed lectures and laboratories in large class settings and by the hands-on, laboratory-based, inquiry-based course taught in a small class setting.

    While persuasive evidence has accumulated over the past 15 years documenting an association between schizophrenia and violence, there are 3 unresolved issues. First, does a downward extension of this relationship exist at the nonclinical level with respect to schizotypal personality and aggression in children? Second, is aggression more associated with impulsive reactive aggression or with more planned proactive aggression. Third and importantly, does peer victimization mediate the relationship between schizotypy and aggression? A further aim of this cross-sectional study was to examine the utility of a new child self-report measure of schizotypal personality. These issues were examined in a sample of 3804 schoolchildren assessed on schizotypy using the Schizotypal Personality Questionnaire-Child (SPQ-C), reactive-proactive aggression, and peer victimization. A confirmatory factor analysis confirmed the 3-factor structure (cognitive-perceptual, interpersonal, and disorganized) of the SPQ-C. Schizotypy was positively associated with total aggression and reactive aggression but not with proactive aggression. Peer victimization was found to significantly mediate the schizotypy-aggression relationship, accounting for 58.9% of the association. Results are broadly consistent with the hypothesis that schizotypal features elicit victimization from other children, which in turn predisposes to reactive retaliatory aggression. Findings are to the authors’ knowledge the first to document any mediator of the schizotypy-aggression relationship and have potential treatment implications for violence reduction in schizophrenia-spectrum disorders. This study also provides initial evidence for the factorial and discriminant validity of a brief and simple measure of schizotypal personality in children as young as 8 years. PMID:21795613

    Whether avoidant personality disorder symptoms are related to neurocognitive impairments that aggregate in relatives of schizophrenics is unknown. We report the relationship between avoidant personality disorder symptoms and neurocognitive performance in the first-degree relatives of probands with schizophrenia. 367 first-degree relatives of probands with schizophrenia and 245 relatives of community controls were interviewed for the presence of avoidant personality symptoms and symptoms of paranoid and schizotypal personality disorders and administered neurocognitive measures. Relationships between neurocognitive measures and avoidant symptoms were analyzed using linear mixed models. Avoidant dimensional scores predicted performance on the span of apprehension (SPAN), 3-7 Continuous Performance Test (3-7 CPT), and Trail Making Test (TMT-B) in schizophrenia relatives. These relationships remained significant on the SPAN even after adjustment for paranoid or schizotypal dimensional scores and on the TMT-B after adjustment for paranoid dimensional scores. Moreover, in a second set of analyses comparing schizophrenia relatives to controls there were significant or trending differences in the degree of the relationship between avoidant symptoms and each of these neurocognitive measures even after adjustments for paranoid and schizotypal dimensional scores. The substantial correlation between avoidant and schizotypal symptoms suggests that these personality disorders are not independent. Avoidant and in some cases schizotypal dimensional scores are significant predictors of variability in these neurocognitive measures. In all analyses, higher levels of avoidant symptoms were associated with worse performance on the neurocognitive measures in relatives of schizophrenia probands. These results support the hypothesis that avoidant personality disorder may be a schizophrenia spectrum phenotype. (c) 2009 Elsevier B.V. All rights reserved.

    Local public resistance can block the site-selection process, construction, and operation of nuclear waste repositories. Social science has established that the perception of risks and benefits, trust in authorities, and opinion on nuclear energy play important roles in acceptance. In particular, risk and benefit evaluations seem critical for opinion formation. However, risks and benefits have rarely been studied independently and, most often, the focus has been on the two most salient groups of proponents and opponents. The aim of this exploratory study is to examine the often-neglected majority of people holding ambivalent or indifferent opinions. We used cluster analysis to examine the sample (N = 500, mailed survey in German-speaking Switzerland) in terms of patterns of risk and benefit perception. We reveal four significantly different and plausible clusters: one cluster with high-benefit ratings in favor of a repository and one cluster with high-risk ratings opposing it; a third cluster shows ambivalence, with high ratings on both risk and benefit scales and moderate opposition, whereas a fourth cluster seems indifferent, rating risks and benefits only moderately compared to the ambivalent cluster. We conclude that a closer look at the often neglected but considerable number of people with ambivalent or indifferent opinions is necessary. Although the extreme factions of the public will most probably not change their opinion, we do not yet know how the opinion of the ambivalent and indifferent clusters might develop over time. © 2012 Society for Risk Analysis.

    Full Text Available The article describes the development of the self-report Questionnaire of Personality Disorders (VMO, which was constructed on the basis of DSM-IV classification for personality disorders(American Psychiatric Association, 1994, Beck's theory of dysfunctional cognitive schemas (Beck in Freeman, 1990 and psychoanalytic theories of basic personality structures. We focused on the basic experiencing of self and others, which is characteristic of specific personality type. In regard to these theories we believe that personality disorder is a broader term; the disorders within it are not limited to existing DSM-IV axis II categories. The personality disorders are complex phenomenon, which are better described on dimensional then categorical scales as well. The questionnaire consists of 213 items, which correspond to 12 clinical scales (for histrionic, obsessive-compulsive, passive-aggressive, avoidant, dependent, depressive, narcissistic, borderline, antisocial, paranoid, schizoid and schizotypal personality disorders and a lie scale. According to the personality organization theory (Kernberg, 1986 and other psychoanalytic theories it is divided into four parts: for neurotic (histrionic, obsessive-compulsive, passive-aggressive and avoidant disorders, depressive (dependent and depressive disorders, borderline (narcissistic, borderline and antisocial disorders and psychotic disorders (paranoid, schizoid and schizotypal disorders. The questionnaire was administered to 415 adult psychiatric patients and 215 health persons of both sexes. They were compared according to the responses of the questionnaire. The internal reliability of scales is sufficient, but correlation between scales is quite strong. The validity was tested with the Personality Diagnostic Questionnaire (PDQ-4, Hyler, 1994 and through comparing of the results of healthy individuals and psychiatric patients with different diagnosis.

    Model systems of psychosis, such as schizotypy or sleep deprivation, are valuable in informing our understanding of the etiology of the disorder and aiding the development of new treatments. Schizophrenia patients, high schizotypes, and sleep-deprived subjects are known to share deficits in oculomotor biomarkers. Here, we aimed to further validate the schizotypy and sleep deprivation models and investigated, for the first time, their interactive effects on smooth pursuit eye movements (SPEM), prosaccades, antisaccades, predictive saccades, and measures of psychotomimetic states, anxiety, depression, and stress. To do so, n = 19 controls and n = 17 high positive schizotypes were examined after both a normal sleep night and 24 h of sleep deprivation. Schizotypes displayed higher SPEM global position error, catch-up saccade amplitude, and increased psychotomimetic states. Sleep deprivation impaired SPEM, prosaccade, antisaccade, and predictive saccade performance and increased levels of psychotomimetic experiences. Additionally, sleep deprivation reduced SPEM gain in schizotypes but not controls. We conclude that oculomotor impairments are observed in relation to schizotypy and following sleep deprivation, supporting their utility as biomarkers in model systems of psychosis. The combination of these models with oculomotor biomarkers may be particularly fruitful in assisting the development of new antipsychotic or pro-cognitive drugs. © 2017 Society for Psychophysiological Research.

    Panic disorders (PD) which develop in the context of different psychiatric diseases (neurotic, personality disorder and schizotypal disorders) have their own clinical and neurophysiological features. The results of compressive-spectral analysis of EEG (CSA EEG) in patients with panic attack were different depending on the specifics of initial psychiatric status. EEG parameters in patients differed from those in controls. The common feature for all PD patients was the lower spectral density of theta-, alpha- and beta-bands as well as total spectral density without any alterations of region distribution. The decrease of electrical activity of activation systems was found in the groups with neurotic and schizotypal disorders and that of inhibition systems - in the group with schizotypal disorders. The EEG results did not suggest any depression of activation systems in patients with specific personality disorders. The data obtained with CSA EEG mirror the integrative brain activity which determinad of the appearance of PA as well as of nosology of psychiatre disease.

    Deficits in social functioning are an important core feature of mental health. Recently in France, the Activities Daily Life (ADL) scale has been proposed by the French authorities to assess social functioning for all hospitalized patients in a psychiatric ward. The perspective is to use this scale in the financing and organization of mental health services in France. The ADL scale is a 6-item (dressing/undressing, walking/mobility, eating/drinking, using toilets, behaviour, relationships/communication) heteroquestionnaire completed by a health care professional at the beginning of each hospitalization, assessing functioning of patients suffering from mental health diseases. However, limited consensus exists on this scale. The psychometric properties of the ADL scale have not been assessed. There is a pressing need for detailed examination of its performance. The aim of this study was to explore ADL psychometric properties in a sample of hospitalized patients in a psychiatric ward. We retrospectively analyzed data for all episodes of care delivered to hospitalized patients in a psychiatric ward in our French Public Hospital from January 1, 2008 to June 30, 2008. The study involved retrospective review of administrative and medical databases. The following data were collected: age, gender, diagnoses based on the International Classification of Diseases - 10th version, ADL scale and Assessment of Social Self-Sufficiency scale (ASSS). The psychometric properties were examined using construct validity, reliability, external validity, reproducibility and sensitivity to change. Data analysis was performed using SPSS 15.0 and WINSTEP software. A total of 1066 patients completed the ADL scale. Among them, 49.7% were male, mean age was 36.5 ± 10.8, and 83.5% were single. Schizophrenia, schizotypal and delusional disorders (40.0%), mood disorders (27.9%) and mental and behavioural disorders due to psychoactive substance use (12%) were the most common diagnoses.

    This study aimed to examine whether stigma-reducing conditions (i.e., random assignment of participants to hypothetical scenarios with varying levels of stigma) effectively increase intention to seek help for Korean college students with anxious-ambivalent attachment style, depending on previous counseling experience. Three hundred thirty Korean college students participated and were randomly assigned to either a low or a high stigma-reducing manipulative condition group. Each group was provided with three possible strategies to reduce stigma: the location of a counseling center, contact with a mental health patient, and the media portrayal of mental illness. In the high-stigma group, the strategies were described in a way that was highly stigmatizing. In the other group, the 3 strategies were created in a way that was not as stigmatizing. In order to examine the effect of stigma-reducing scenarios through the conditions, participants were also instructed to remember a previous or current stressful situation before responding to the questionnaire. The results of multivariate analysis of variance showed a 3-way interaction effect (i.e., level of stigma based on stigma manipulative condition, level of attachment anxiety, and previous counseling experience) on the intentions score when the "contact" and the "media" strategies were applied. The results indicated that individuals who have a higher level of attachment anxiety and a previous experience of counseling were more sensitive to the stigma-reducing manipulative condition. These results highlight the importance of the "contact" and "media" strategies in reducing stigma of seeking counseling for mental health services. (c) 2015 APA, all rights reserved).

    Attentional-interference using emotional Stroop tasks (ESTs) is greater among individuals in the general population with positive (versus negative) schizotypal traits; specifically in response to negatively (versus positively) valenced words, potentially capturing threat-sensitivity. Variability in attentional-interference as a function of subcategories of negatively valenced words (and in relation to schizotypal traits) remains underexplored in EST studies. We examined attentional-interference across negative word subcategories (fear/anger/sadness/disgust), and in relation to positive schizotypy, among non-clinical individuals in the general population reporting varying degrees of schizotypal traits. As hypothesized, performance differed across word subcategories, though the pattern varied from expectation. Attentional-interference was greater for fear and sadness compared to anger; and analogous for fear, disgust, and sadness. In the high schizotypy group, positive schizotypal traits were directly associated with attentional-interference to disgust. Attentional-interference was comparable between high- and low-positive schizotypy. Results suggest negative emotion subcategories may differentially reflect threat-sensitivity. Disgust-sensitivity may be particularly salient in (non-clinical) positive schizotypy. Findings have implications for understanding negative emotion specificity and variability in stimulus presentation modality when studying threat-related attentional-interference. Finally, disgust-related attentional-interference may serve as a cognitive correlate of (non-clinical) positive schizotypy. Expanding this research to prodromal populations will help explore disgust-related attentional-interference as a potential cognitive marker of positive symptoms.

    Full Text Available No diagnóstico da modernidade, incerteza e insegurança - e portanto o medo - são elementos presentes. Partindo dessa constatação, este trabalho tem por objetivo descrever os efeitos ambivalentes do medo sobre a sociedade contemporânea. Nesta tentativa, busca-se o apoio de diversas teorias sociais que, embora não enfoquem o medo, mostram de certa forma os riscos constantes do processo de modernização. Por outro lado, isso permite separar a crítica social que ainda tenta continuar pensando a modernidade com base nas premissas conceituais da razão ocidental, de uma outra, que por sua própria fadiga proclama sua autodestruição. Entende-se aqui que se despedir da razão e considerar o movimento autônomo da modernidade é fazer surgir um processo que apenas garante a modernização do medo.In the diagnosis of the modernity, uncertainty and insecurity - and therefore the fear - they are present elements. Leaving of that verification, this work has for objective to describe the ambivalent effects of the fear on the contemporary society. In that attempt, the support of several social theories is looked for that, although they don't focus the fear, they show the constant risks of the modernization process in a certain way. On the other hand, that allows to separate the social critic, that it still tries to continue thinking the modernity with base about the conceptual premises of the western reason, of another one, that for your own fatigue proclaims your self-destruction. Understands each other here that to say good-bye of the reason and to consider the autonomous movement of the modernity is to do a process that just guarantees the modernization of the fear to appear.

In addition, to determine the impact of socio-demographic variables such as age, gender and educational level over stress symptoms hereby comprises a further objective of this study. Method: The study included totally 129 tuberculosis patients and 161 non-patients (normal group participants. Tuberculosis patients registered in Ankara Tuberculosis Dispensary No.4, and Atatürk Chest Diseases and Chest Surgery Hospital. There are 75 Pulmonary Tuberculosis (AC TB and 54 Extra- Pulmonary Tuberculosis (AD TB patients. As regards data collection tools; Demographic Information Form, Brief Symptom Inventory, Stress Symptoms Scale, Stress Vulnerability Scale, and Stress Coping Scale were used. Results: Within the context of diagnosis groups; it was found that; stress symptoms of tuberculosis patients are higher than the normal group, they use their ineffective coping ways more and their life satisfactions are lower. There exists no gender and diagnosis group main effect in terms of the psychological symptoms of stress, however “gender x diagnosis group” interaction effect draws attention herein. In tuberculosis patients, ineffective coping the stress and relation pleasure variables are confronted as joint variables which are predicting both the psychological and physical health. Another point which draws attention in regression analyzes is that; “education” variable takes place among the variables which predict the psychological symptoms of stress in tuberculosis patients. Conclusion: Under the light of these findings, tuberculosis patients, during their treatment processes, may be encouraged to attend various training programs prepared for stress management and effective dealing strategies with stress. By increasing the patients’ motivation towards the treatment, these programs may provide supplementary benefits to the treatment by

    Full Text Available The experience of hallucinations is a hallmark of psychotic disorders, but they are also present in other psychiatric and medical conditions, and may be reported in nonclinical individuals. Despite the increased number of studies probing the incidence of nonclinical hallucinations, the underlying phenomenological characteristics are still poorly understood. This study aimed to examine the psychometrics proprieties of the Portuguese adaptation of the 16-item Launay-Slade Hallucinations Scale (LSHS, the phenomenological characteristics of nonclinical hallucinatory experiences in a Portuguese sample, and the relationship between clinical symptoms and hallucination predisposition. Three-hundred-and-fifty-four European Portuguese college students completed the LSHS. Of those, 16 participants with high LSHS scores and 14 with low LSHS scores were further screened for clinical symptoms. A three-factor solution for the LSHS Portuguese version proved to be the most adequate. Intrusive or vivid thoughts and sleep-related hallucinations were the most common. Although, fundamentally perceived as positive experiences, all types of hallucinations were described as uncontrollable and dominating. However, the more pleasant they were perceived, the more controllable they were assessed. In addition, hallucination predisposition was associated with increased clinical symptoms. These results corroborate the lower severity of hallucinations in the general population compared to psychotic individuals. Further, they support an association between clinical symptoms and increased vulnerability to hallucinations. Specifically, increased schizotypal tendencies and negative mood (anxiety and depression may be related to increased psychotic risk.

    The purpose of this study is to test the reliability and validity of a Spanish translation of the Resilience Scale (RS), which was originally created in English by Wagnild and Young (1993). A team of bilingual, bicultural translators participated in the translation process to enhance the linguistic accuracy and cultural appropriateness of the Spanish translation. As part of the convenience sample of 315 women of Mexican descent who participated in the larger study, data from 147 women who preferred to read and write in Spanish were used in this analysis. The English version of the RS consists of a 17-item "Personal Competence" subscale and an 8-item "Acceptance of Self and Life" subscale for a total of 25 items. However, two items had low item-total loadings and were removed to form a modified 23-item RS. The exploratory principal components factor analysis, varimax rotation, and subsequent goodness of fit indices were ambivalent on whether a one or two-factor solution was appropriate, but the chi-square difference test clearly demonstrated that the two-factor solution of the Spanish version was more useful in explaining variance than a one-factor solution. Internal consistency reliability was estimated with Cronbach's alpha (alpha = 0.93) which was acceptable for the 23-item RS as well as its subscales. Construct validity was demonstrated by a significant positive correlation between resilience and life satisfaction (r = 0.36; p resilience and depressive symptoms (r = -0.29; p urban, low-income women of Mexican descent in the U.S.

    Full Text Available We studied the concurrent, predictive, and discriminate validity of psychopathology scales (e.g., schizotypal and depressive and temperament traits for hospitalisations due to major depression. Temperament, perceptual aberration, physical and social anhedonia, Depression Subscale of Symptom Checklist (SCL-D, Hypomanic Personality Scale, Schizoidia Scale, and Bipolar II Scale were completed as part of the 31-year follow-up survey of the prospective Northern Finland 1966 Birth Cohort (n=4941; 2214 males. Several of the scales were related to depression. Concurrent depression was especially related to higher perceptual aberration (effect size when compared to controls, d=1.29, subsequent depression to high scores in SCL-D (d=0.48. Physical anhedonia was lower in subjects with subsequent depression than those with other psychiatric disorders (d=−0.33, nonsignificant. Participants with concurrent (d=0.70 and subsequent (d=0.54 depression had high harm avoidance compared to controls, while differences compared to other psychiatric patients were small. Subjects with depression differed from healthy controls in most of the scales. Many of the scales were useful predictors for future hospital treatments, but were not diagnosis-specific. High harm avoidance is a potential indicator for subsequent depression.

    Full Text Available Ironic remarks are frequent in everyday language and represent an important form of social cognition. Increasing evidence indicates a deficit in comprehension in schizophrenia. Several models for defective comprehension have been proposed, including possible roles of the medial prefrontal lobe, default mode network, inferior frontal gyri, mirror neurons, right cerebral hemisphere and a possible mediating role of schizotypal personality traits. We investigated the neural correlates of irony comprehension in schizophrenia by using event-related functional magnetic resonance imaging (fMRI. In a prosody-free reading paradigm, 15 female patients with schizophrenia and 15 healthy female controls silently read ironic and literal text vignettes during fMRI. Each text vignette ended in either an ironic (n = 22 or literal (n = 22 statement. Ironic and literal text vignettes were matched for word frequency, length, grammatical complexity, and syntax. After fMRI, the subjects performed an off-line test to detect error rate. In this test, the subjects indicated by button press whether the target sentence has ironic, literal, or meaningless content. Schizotypal personality traits were assessed using the German version of the schizotypal personality questionnaire (SPQ. Patients with schizophrenia made significantly more errors than did the controls (correct answers, 85.3% vs. 96.3% on a behavioural level. Patients showed attenuated blood oxygen level-dependent (BOLD response during irony comprehension mainly in right hemisphere temporal regions (ironic>literal contrast and in posterior medial prefrontal and left anterior insula regions (for ironic>visual baseline, but not for literal>visual baseline. In patients with schizophrenia, the parahippocampal gyrus showed increased activation. Across all subjects, BOLD response in the medial prefrontal area was negatively correlated with the SPQ score. These results highlight the role of the posterior medial

    To evaluate the status of schizotypy, neurological soft signs, and cognitive functions as vulnerability markers for schizophrenia and to investigate the potential value of their combination for early identification of people at high risk for schizophrenia. A cross-sectional study was conducted. Subjects were drawn from first-degree relatives of inpatients and outpatients with schizophrenia (n = 50). Controls (n = 30) were recruited by word-of-mouth from hospital staff and attendants of hospitalised patients. Subjects who met inclusion criteria on screening were subjected to selected measures for assessment, including Schizotypal Personality Questionnaire-Brief Version, the Cambridge Neurological Inventory, digit span test, paired associate learning test, and visuospatial working memory matrix. Statistical analysis was completed using the independent t test and significance (p value), as well as calculation of effect size (Cohen's d). Discriminant function analysis was used to determine the effect of combining assessment measures. First-degree relatives showed higher schizotypy scores (Cohen's d = 0.88) and neurological soft signs (Cohen's d = 1.55). They scored significantly worse on all neurocognitive measures (Cohen's d = -1.27). Discriminant function analysis showed that Schizotypal Personality Questionnaire-Brief Version, neurological soft signs, and total cognitive index (the sum of weighted scores on individual cognitive scales) in combination better discriminated between the first-degree relative and control groups (Wilks' λ = 0.54). Use of multiple vulnerability markers could enhance the specificity of measures used to determine risk for schizophrenia.

    Despite a relatively strong family planning program and regionally modest levels of fertility, Ghana recorded one of the highest levels of unmet need for family planning on the African continent in 2008. Unmet need for family planning is a composite measure based on apparent contradictions between women's reproductive preferences and practices. Women who want to space or limit births but are not using contraception are considered to have an unmet need for family planning. The study sought to understand the reasons behind high levels of unmet need for family planning in Ghana. A mixed methods follow-up study was embedded within the stratified, two-stage cluster sample of the 2014 Ghana Demographic and Health Survey (GDHS). Women in 13 survey clusters who were identified as having unmet need, along with a reference group of current family planning users, were approached to be reinterviewed within an average of three weeks from their GDHS interview. Follow-up respondents were asked a combination of closed- and open-ended questions about fertility preferences and contraceptive use. Closed-ended responses were compared against the original survey; transcripts were thematically coded and analyzed using qualitative analysis software. Among fecund women identified by the 2014 GDHS as having unmet need, follow-up interviews revealed substantial underreporting of method use, particularly traditional methods. Complete postpartum abstinence was sometimes the intended method of family planning but was overlooked during questions about method use. Other respondents classified as having unmet need had ambivalent fertility preferences. In several cases, respondents expressed revised fertility preferences upon follow-up that would have made them ineligible for inclusion in the unmet need category. The reference group of family planning users also expressed unstable fertility preferences. Aversion to modern method use was generally more substantial than reported in the GDHS

This work is divided into two phases: our goal in Phase I was to investigate whether any similarity exists in the prejudice response profiles of parents and their young adult offspring. Phase II sought to uncover the levels of unique similarity between parents and child in gender prejudice (cultural stereotype effect. Participants were 293 Italian families (young adult child, mother and father, for a total of 879 people. Each participants completed the Ambivalent Sexism (Glick & Fiske, 1996 and Ambivalence toward Men (Glick & Fiske, 1999 scales. As our research included family data, specific analysis were used, such dyadic indexes (Kenny, Kashy & Cook, 2006. Results reveal that (1 the response profiles of parents and offspring are dissimilar, and (2 the slight shared variance between them is determined by the cultural stereotype effect.

    Full Text Available Abstract Background Parents' reported ambivalence toward large-scale vaccination programs for childhood diseases may be related to their perception of the risks of side-effects or safety of vaccination and the risk of contracting the disease. The aim of this study is to evaluate parents' perceptions of their child's risk contracting a Meningococcal C infection and parents' perceived control in preventing infection in relation to their evaluation of the safety, effectiveness and usefulness of vaccination. Methods In a large-scale interview study, a random sample of parents was interviewed after their children had received vaccination against Meningococcal C in a catch-up campaign. Questions were asked about the perceived relative vulnerability of their child contracting an infection, perceived control in preventing an infection, and parents' evaluation of the safety, usefulness and effectiveness of vaccination. Results 61% of 2910 (N = 1763 parents who were approached participated. A higher perceived relative vulnerability of their own child contracting the disease was related to a more positive evaluation of the vaccination campaign, while a lower perceived vulnerability did not result in a more negative evaluation. A higher perceived control in being able to prevent an infection was, however, related to a more critical attitude toward the safety, usefulness and effectiveness of vaccination. Conclusion Perceived relative vulnerability contracting an infection and parents' perceived control in preventing an infection seem to influence parents' evaluation of the vaccination programme. Future studies should determine if, and under which circumstances, these perceptions also affect parents' vaccination behaviour and would be relevant to be taken into account when educating parents about vaccination.

    Full Text Available Technique has been a discussion topic since philosophy´s origins, although not many times has it been approached beyond prejudices and simplistic categories. In the 20th century and in the 21st century we have witnessed a rise in the number of works concerning technology, primarily due to the omnipresence and preeminence of modern technology in our lives. Nonetheless, this works have once again fallen short of creating a true philosophy of technology, remaining as demonizing works (technophobic or as praising works (technophilic. One of the exceptions to this reductionist dinamic is Ortega´s philosophy of technology, a relatively unknown aspect of his thought, has nonetheless a great potential as a way of understanding our technologized present.

  4. Do complaints of everyday cognitive failures in high schizotypy relate to emotional working memory deficits in the lab?

    Individuals high on schizotypy complain of increased cognitive failures in everyday life. However, the neuropsychological performance of this group does not consistently indicate underlying ability deficits. It is possible that current neuropsychological tests lack ecological validity. Given the increased affective reactivity of high schizotypes, they may be more sensitive to emotional content interfering with cognitive ability. This study sought to explore whether an affective n-back working memory task would elicit impaired performance in schizotypy, echoing complaints concerning real world cognition. 127 healthy participants completed self-report measures of schizotypy and cognitive failures and an affective n-back working memory task. This task was varied across three levels of load (1- to 3-back) and four types of stimulus emotion (neutral, fearful, happy, sad). Differences between high (n=39) and low (n=48) schizotypy groups on performance outcomes of hits and false alarms were examined, with emotion and load as within-groups variables. As expected, high schizotypes reported heightened vulnerability to cognitive failures. They also demonstrated a relative working memory impairment for emotional versus neutral stimuli, whereas low schizotypes did not. High schizotypes performed most poorly in response to fearful stimuli. For false alarms, there was an interaction between schizotypy, load, and emotion, such that high schizotypy was associated with deficits in response to fearful stimuli only at higher levels of task difficulty. Inclusion of self-reported cognitive failures did not account for this. These findings suggest that the "gap" between subjective and objective cognition in schizotypy may reflect the heightened emotional demands associated with cognitive functioning in the real world, although other factors also seem to play a role. There is a need to improve the ecological validity of objective assessments, whilst also recognizing that self

    possible alterations of ToM processing in individuals with schizotypy or subsyndromal psychotic symptoms. METHODS: We performed a search on MedLine database for articles published in English or Portuguese between 1990 and 2008, using the phrase "Schizotypal Personality Disorder [MeSH] AND "Theory of Mind" OR "Mentalising". RESULTS: Fifteen manuscripts have been selected, which used diverse experimental designs and instruments to evaluate schizotypal traits, vulnerability to psychosis and ToM abilities. DISCUSSION: The reviewed articles aimed to establish relationships between vulnerability to psychosis and alterations in ToM processing. Some articles also approached the trait or state dependence character of ToM impairments. The great majority of the selected manuscripts suggested that individuals who scored high in schizotypy scales, as well as schizophrenic relatives, do show problems in ToM processing (which suggests a trait dependence character. However, these results should be interpreted carefully due to methodological problems seen in the majority of the studies.

    There are indications that subjects with schizotypal personality have a lower Body Mass Index. Also schizotypal personality is linked to a higher incidence of paranormal belief. In this study we examined whether low Body Mass Index is also linked to paranormal belief. In a pilot study 48 students of psychology (85.4% women) between the ages of 20 and 27 years were administered a questionnaire assessing weight, height, and paranormal belief. Analysis suggested an association between belief in paranormal phenomena and low Body Mass Index. In a follow-up study with 300 subjects and equal sex distribution, the relationship was examined under control of schizotypy. The results for Body Mass Index could not be confirmed; however, paranormal belief was heavily associated with the cognitive-perceptual component of schizotypy.

    Full Text Available Objective: Based on the past studies in the filed of substance abuse, this study is to compare at risk populations regarding to familial and individual factors. Materials & Methods: this study have been done on 716 at risk individual in 11 city of Fars province. Research tools includes:1- locus of control inventory 2- Attachment styles scale 3- Parental Bonding Instrument 4- Resilience Scale 5- Coping Skills Inventory 6- Self Esteem scale. Results: there was a significant difference between normal and user and abuser groups. In resiliency, self esteem, problem oriented coping skills, caring and secure attachment normal group had a higher scores. But in ambivalent attachment style, external locus of control, emotion oriented and less benefit coping skills, normal group had a lower scores. In resiliency, ambivalent attachment style, problem oriented coping skills, and less benefit coping skills there was significant differences between user and abuser groups. But this was not true for caring, overprotection, secure attachment, locus of control, self esteem, and emotion oriented coping skills. Conclusion: according to these finding and in order to development and promotion of resiliency for substance abuse, preventive intervention should focus on educating parents and caregivers in the field of caring, enough protection, developing secure attachment, strategies for development and maintenance of self esteem, internal locus of control, and use of problem oriented coping skills. Psychological interventions also can use these finding in order to focus their therapy goals.

    Clinical and phenomenological accounts of schizophrenia suggest that impairments in self-reflective processes significantly contribute to psychopathological expression. Recent imaging studies observe atypical cerebral activation patterns during self-reflection, especially around the cortical midline structures, both in psychosis-prone adults and individuals with schizophrenia. Given that self-reflection processes consolidate during adolescence, and that early transient expression of psychosis (positive schizotypy) also arises during this period, the present study sought to examine whether atypical cerebral activation during self-reflection task could be associated with early schizotypic expression during adolescence. Forty-two neurotypical adolescent participants (19 females) aged from 12 to 19 (15.92±1.9) underwent a self-reflection task using functional neuroimaging (fMRI), where they had to evaluate trait adjectives (1 to 4 ratings) about themselves or their same sex best friend. The Schizotypal Personality Questionnaire (SPQ) was employed to assess positive schizotypic expression. Results showed that positive schizotypy in adolescents significantly correlated with cortical midline activation patterns in the dorsomedial prefrontal cortex (dmPFC) and the posterior cingulate cortex (PCC), as well as the dorsolateral PFC and the lingual gyrus. The results are consistent with previous imaging literature on self-reflection and schizophrenia. They further highlight that the relationship between self-reflection processes and positive schizotypy operates at the trait level of expression and can be observed as early as adolescence.

    Speech deficits are thought to be an important feature of schizotypy--defined as the personality organization reflecting a putative liability for schizophrenia. There is reason to suspect that these deficits manifest as a function of limited cognitive resources. To evaluate this idea, we examined speech from individuals with psychometrically-defined schizotypy during a low cognitively-demanding task versus a relatively high cognitively-demanding task. A range of objective, computer-based measures of speech tapping speech production (silence, number and length of pauses, number and length of utterances), speech variability (global and local intonation and emphasis) and speech content (word fillers, idea density) were employed. Data for control (n=37) and schizotypy (n=39) groups were examined. Results did not confirm our hypotheses. While the cognitive-load task reduced speech expressivity for subjects as a group for most variables, the schizotypy group was not more pathological in speech characteristics compared to the control group. Interestingly, some aspects of speech in schizotypal versus control subjects were healthier under high cognitive load. Moreover, schizotypal subjects performed better, at a trend level, than controls on the cognitively demanding task. These findings hold important implications for our understanding of the neurocognitive architecture associated with the schizophrenia-spectrum. Of particular note concerns the apparent mismatch between self-reported schizotypal traits and objective performance, and the resiliency of speech under cognitive stress in persons with high levels of schizotypy.

    Background While it is well known that personality disorders are associated with trauma exposure and PTSD, limited nationally representative data are available on DSM-IV personality disorders that co-occur with posttraumatic stress disorder (PTSD) and partial PTSD. Methods Face-to-face interviews were conducted with 34,653 adults participating in the Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions. Logistic regression analyses controlling for sociodemographics and additional psychiatric comorbidity evaluated associations of PTSD and partial PTSD with personality disorders. Results Prevalence rates of lifetime PTSD and partial PTSD were 6.4% and 6.6%, respectively. After adjustment for sociodemographic characteristics and additional psychiatric comorbidity, respondents with full PTSD were more likely than trauma controls to meet criteria for schizotypal, narcissistic, and borderline personality disorders (ORs=2.1–2.5); and respondents with partial PTSD were more likely than trauma controls to meet diagnostic criteria for borderline (OR=2.0), schizotypal (OR=1.8), and narcissistic (OR=1.6) PDs. Women with PTSD were more likely than controls to have obsessive-compulsive PD. Women with partial PTSD were more likely than controls to have antisocial PD; and men with partial PTSD were less likely than women with partial PTSD to have avoidant PD. Conclusions PTSD and partial PTSD are associated with borderline, schizotypal, and narcissistic personality disorders. Modestly higher rates of obsessive-compulsive PD were observed among women with full PTSD, and of antisocial PD among women with partial PTSD. PMID:20950823

  12. [The concept of schizoidia in psychiatry : From schizoidia to schizotypy and cluster A personality disorders].

    Kapfhammer, Hans-Peter

    2017-12-01

    From a perspective of conceptual evolution schizoidia was initially considered to describe features both of the premorbid personality of schizophrenic patients and of the personalities of non-psychotic family members (Bleuler, Kahlbaum, Kraepelin). On a psychopatholocial level a close link to the complex basic symptom of autism was stressed. From the very beginnings of modern psychiatry schizoidia was discussed within a conceptual frame of schizophrenia spectrum disorders (Kretschmer, Hoch, Polatin). Approaches to operationalize these conceptual works laid the basis for the cluster A personalities in DSM-III. Due to the prominent concept of schizotypy (Kety, Rado, Meehl) three split up diagnostic categories of schizotypal, schizoid and paranoid personality disorders resulted. Cluster A personality disorders are frequent in community-based epidemiological studies. Health-care seeking behaviour due to primary personality-related problems, however, seems to be less paramount compared to cluster B and C personality disorders. Many family- and twin-based genetic studies convincingly stress a close link between schizotypal personality disorder and schizophrenia. This link is less pronounced for paranoid personality disorder, and even vanishingly low for schizoid personality disorder. From a perspective of schizophrenia spectrum disorders a vast amount of data from molecular genetic, neurobiological, neuropsychological and psychosocial research has impressingly confirmed this link for schizotypal personality disorder. Major research deficits, however, have to be noticed for paranoid and schizoid personality disorder.

    Fourteen men scoring high and 14 men scoring low on a positive schizotypy scale participated in a lateralized emotional Stroop task. Vocal reaction times for color naming of neutral, positive and negative emotional words were recorded. Across participants, the color naming of neutral and emotional words was slightly faster to right than to left visual field presentations. In men with high scores on positive schizotypy, the presentation of negative words to the left visual field (right hemisphere) resulted in significant affective interference with color naming, which was significantly larger than in men with low scores. Correlational analysis also showed that positive schizotypy was significantly associated with emotional interference in response to LVF negative words. The outcome is discussed in terms of right hemispheric engagement in negative emotions in high positive schizotypic men.

    Full Text Available Despite growing evidence for demonstrated efficacy of mindfulness in various disorders, there is a continuous concern about the relationship between mindfulness practice and psychosis. As schizotypy is part of the psychosis spectrum, we examined the relationship between long-term mindfulness practice and schizotypy in two independent studies. Study 1 included 24 experienced mindfulness practitioners (19 males from the Buddhist tradition (meditators and 24 meditation-naïve individuals (all males. Study 2 consisted of 28 meditators and 28 meditation-naïve individuals (all males. All participants completed the Schizotypal Personality Questionnaire (Raine, 1991, a self-report scale containing 9 subscales (ideas of reference, excessive social anxiety, magical thinking, unusual perceptual experiences, odd/eccentric behavior, no close friends, odd speech, constricted affect, suspiciousness. Participants of study 2 also completed the Five-Facet Mindfulness Questionnaire which assesses observing (Observe, describing (Describe, acting with awareness (Awareness, non-judging of (Non-judgment and non-reactivity to inner experience (Non-reactivity facets of trait mindfulness. In both studies, meditators scored significantly lower on suspiciousness and higher on magical thinking compared to meditation-naïve individuals and showed a trend towards lower scores on excessive social anxiety. Excessive social anxiety correlated negatively with Awareness and Non-judgment; and suspiciousness with Awareness, Non-judgment and Non-reactivity facets across both groups. The two groups did not differ in their total schizotypy score. We conclude that mindfulness practice is not associated with an overall increase in schizotypal traits. Instead, the pattern suggests that mindfulness meditation, particularly with an emphasis on the Awareness, Non-judgment and Non-reactivity aspects, may help to reduce suspiciousness and excessive social anxiety.

  17. Relating Schizotypy and Personality to the Phenomenology of Creativity

    2010-01-01

    Introduction: Although a considerable amount of research has addressed psychopathological and personality correlates of creativity, the relationship between these characteristics and the phenomenology of creativity has been neglected. Relating these characteristics to the phenomenology of creativity may assist in clarifying the precise nature of the relationship between psychopathology and creativity. The current article reports on an empirical study of the relationship between the phenomenology of the creative process and psychopathological and personality characteristics in a sample of artists. Method: A total of 100 artists (43 males, 57 females, mean age = 34.69 years) from a range of disciplines completed the Experience of Creativity Questionnaire and measures of “positive” schizotypy, affective disturbance, mental boundaries, and normal personality. Results: The sample of artists was found to be elevated on “positive” schizotypy, unipolar affective disturbance, thin boundaries, and the personality dimensions of Openness to Experience and Neuroticism, compared with norm data. Schizotypy was found to be the strongest predictor of a range of creative experience scales (Distinct Experience, Anxiety, Absorption, Power/Pleasure), suggesting a strong overlap of schizotypal and creative experience. Discussion: These findings indicate that “positive” schizotypy is associated with central features of “flow”-type experience, including distinct shift in phenomenological experience, deep absorption, focus on present experience, and sense of pleasure. The neurologically based construct of latent inhibition may be a mechanism that facilitates entry into flow-type states for schizotypal individuals. This may occur by reduced latent inhibition providing a “fresh” awareness and therefore a greater absorption in present experience, thus leading to flow-type states. PMID:18682376

    Some individuals with obsessive-compulsive disorder (OCD) have autistic-like traits, including deficits in social and communication behaviors (pragmatics). The objective of this study was to determine if pragmatic impairment aggregates in OCD families and discriminates a clinically and genetically distinct subtype of OCD. We conducted clinical examinations on, and collected DNA samples from, 706 individuals with OCD in 221 multiply affected OCD families. Using the Pragmatic Rating Scale (PRS), we compared the prevalence of pragmatic impairment in OCD-affected relatives of probands with and without pragmatic impairment. We also compared clinical features of OCD-affected individuals in families having at least one, versus no, individual with pragmatic impairment, and assessed for linkage to OCD in the two groups of families. The odds of pragmatic impairment were substantially greater in OCD-affected relatives of probands with pragmatic impairment. Individuals in high-PRS families had greater odds of separation anxiety disorder and social phobia, and a greater number of schizotypal personality traits. In high-PRS families, there was suggestive linkage to OCD on chromosome 12 at marker D12S1064 and on chromosome X at marker DXS7132 whereas, in low-PRS families, there was suggestive linkage to chromosome 3 at marker D3S2398. Pragmatic impairment aggregates in OCD families. Separation anxiety disorder, social phobia, and schizotypal personality traits are part of a clinical spectrum associated with pragmatic impairment in these families. Specific regions of chromosomes 12 and X are linked to OCD in high-PRS families. Thus, pragmatic impairment may distinguish a clinically and genetically homogeneous subtype of OCD. © 2014 Wiley Periodicals, Inc.

    Atypical lateralization for language has been found in schizophrenia, suggesting that language and thought disorders on the schizophrenia spectrum may be due to left hemispheric dysfunction. However, research with those with non-clinical schizotypy has been inconsistent, with some studies finding reduced or reversed language laterality (particularly with positive schizotypal traits), and others finding typical left hemispheric specialization. The aim of the current study was to use both a behavioural (dual reading-finger tapping) task and an functional magnetic resonance imaging lexical decision task to investigate language laterality in a university sample of high- and low-schizotypal adults. Findings revealed no evidence for atypical lateralization in our sample for both overall schizotypy (measured by the Oxford-Liverpool Inventory of Feelings and Experiences) and positive schizotypy (measured by the Unusual Experiences subscale) groups. Our findings provide further evidence that non-clinical schizotypy is not associated with atypical language laterality.

    Individuals with schizophrenia have been found to exhibit emotion-behavior decoupling, particularly with respect to anticipated, rather than experienced events. However, previous research has focused on how emotion valence translates into motivated behavior, ignoring the fact that emotion arousal should also modulate emotion-behavior coupling. Few studies have examined emotion-behavior coupling in prepsychotic conditions. This investigation aimed to examine the nature and extent of emotion valence- and arousal-behavior coupling across the schizophrenia spectrum. We examine how emotional valence and arousal couple with behavior in 3 groups of individuals (25 individuals with chronic schizophrenia; 27 individuals early in the disease course, and 31 individuals reporting negative schizotypal symptoms). Participants completed a task using slides to elicit emotion and evoke motivated behavior. We compared participants with their respective matched control groups to determine differences in the correspondence between self-reported emotion valence/arousal and motivated behavior. Both groups with schizophrenia reported similar affective experiences as their controls, whereas individuals reporting negative schizotypal symptoms showed "in-the-moment" anhedonia but not emotion-behavior decoupling. In addition, the schizophrenia groups' affective experiences corresponded less well to their behavior relative to controls. Our findings suggest emotion-behavior decoupling along both valence and arousal dimensions in schizophrenia but not in participants with high levels of schizotypal symptoms. Findings appear to support the idea that emotion-behavior decoupling differs in nature and extent across the schizophrenia spectrum. Interventions to recouple emotion and behavior may be particularly helpful in allowing people with schizophrenia to gain functional independence.

    Full Text Available Insecure attachment styles have received theoretical attention and some initial empirical support as mediators between childhood adverse experiences and psychotic phenomena; however, further specificity needs investigating. The present interview study aimed to examine (i whether two forms of poor childhood care, namely parental antipathy and role reversal, were associated with subclinical positive and negative symptoms and schizophrenia-spectrum personality disorder (PD traits, and (ii whether such associations were mediated by specific insecure attachment styles.A total of 214 nonclinical young adults were interviewed for subclinical symptoms (Comprehensive Assessment of At-Risk Mental States, schizophrenia-spectrum PDs (Structured Clinical Interview for DSM-IV Axis II Disorders, poor childhood care (Childhood Experience of Care and Abuse Interview, and attachment style (Attachment Style Interview. Participants also completed the Beck Depression Inventory-II and all the analyses were conducted partialling out the effects of depressive symptoms.Both parental antipathy and role reversal were associated with subclinical positive symptoms and with paranoid and schizotypal PD traits. Role reversal was also associated with subclinical negative symptoms. Angry-dismissive attachment mediated associations between antipathy and subclinical positive symptoms and both angry-dismissive and enmeshed attachment mediated associations of antipathy with paranoid and schizotypal PD traits. Enmeshed attachment mediated associations of role reversal with paranoid and schizotypal PD traits.Attachment theory can inform lifespan models of how adverse developmental environments may increase the risk for psychosis. Insecure attachment provides a promising mechanism for understanding the development of schizophrenia-spectrum phenomenology and may offer a useful target for prophylactic intervention.

    2015-12-01

    Although schizotypy has been found to be reliably associated with a reduced recognition of facial affect, the few studies that have tested the association between basic face recognition abilities and schizotypy have found mixed results. This study formally tested the association in a large non-clinical sample with established neurological measures of face recognition. Two hundred and twenty-seven participants completed the Oxford-Liverpool Inventory of Feelings and Experiences schizotypy scale and completed the Famous Faces Test and the Cardiff Repeated Recognition Test for Faces. No association between any schizotypal dimension and performance on either of the facial recognition and learning tests was found. The null results can be accepted with a high degree of confidence. Further additional evidence is provided for a lack of association between schizotypy and basic face recognition deficits. © 2014 Wiley Publishing Asia Pty Ltd.

    2016-01-01

    Schizotypy is a personality organisation that is closely related to schizotypal personality disorder and schizophrenia and is characterised by deficits in social functioning. Although the dimensions of social dysfunction have not yet been fully explored certain aspects of social dysfunction are promising predictive markers for schizophrenia. To describe schizotypy and its influence on social functioning. We reviewed the literature systematically using the online databases PubMed and PsycINFO. The disorder known as schizotypy lies at the basis of schizotypal personality disorder. Both disorders are characterised by an increased risk for schizophrenia. The social dysfunctioning seen in schizotypy corresponds to the social dysfunction seen in schizophrenia. Impairments in social cognition are causal factors of this social dysfunction. Both the negative and the positive dimension of schizotypy influence social cognition. More focused, objective and interactive research to the various aspects of social functioning in schizotypy is needed in order to discover potential premorbid markers for schizophrenia.

    While longitudinal magnetic resonance imaging (MRI) studies have demonstrated progressive gray matter reduction of the superior temporal gyrus (STG) during the early phases of schizophrenia, it remains largely unknown whether other temporal lobe structures also exhibit similar progressive changes and whether these changes, if present, are specific to schizophrenia among the spectrum disorders. In this longitudinal MRI study, the gray matter volumes of the fusiform, middle temporal, and inferior temporal gyri were measured at baseline and follow-up scans (mean inter-scan interval=2.7 years) in 18 patients with first-episode schizophrenia, 13 patients with schizotypal disorder, and 20 healthy controls. Both schizophrenia and schizotypal patients had a smaller fusiform gyrus than controls bilaterally at both time points, whereas no group difference was found in the middle and inferior temporal gyri. In the longitudinal comparison, the schizophrenia patients showed significant fusiform gyrus reduction (left, -2.6%/year; right, -2.3%/year) compared with schizotypal patients (left: -0.4%/year; right: -0.2%/year) and controls (left: 0.1%/year; right: 0.0%/year). However, the middle and inferior temporal gyri did not exhibit significant progressive gray matter change in all diagnostic groups. In the schizophrenia patients, a higher cumulative dose of antipsychotics during follow-up was significantly correlated with less severe gray matter reduction in the left fusiform gyrus. The annual gray matter loss of the fusiform gyrus did not correlate with that of the STG previously reported in the same subjects. Our findings suggest regional specificity of the progressive gray matter reduction in the temporal lobe structures, which might be specific to overt schizophrenia within the schizophrenia spectrum.

    Full Text Available There is a lack of information concerning the features of cognitive processes in personality disorders, as well as the brain mechanisms of the pathogenesis of these diseases. Luria’s neuropsychological approach demonstrated its heuristicity in estimating the cognitive status of patients with mental disorders and can be employed to identify the brain bases of non-psychotic mental disorders (including personality disorders. The objective of this research is to study the features of neurocognitive functioning in patients with schizoid personality disorder and schizotypal personality disorder (against the norm, employing Luria’s neuropsychological methodology. Hypotheses: 1 While both types of personality disorders are related to schizophrenia spectrum disorders, the specificity of the neurocognitive functioning of each personality disorder will be observed in addition to general neuropsychological signs. Specific neuropsychological symptoms point to different brain deficits, which allows conclusion to be drawn regarding differences in the pathogenesis of each personality disorder; and 2 Luria’s methodology neuropsychology is adequate for the study of neurocognitive functioning in personality disorders. The study was conducted using qualitative and quantitative analyses (according to Luria of neuropsychological testing data in a group of fifty male patients aged 19,2±3,7 years with pathocharacteristic domain disorders. The group consisted of 30 schizoid personality disorder patients and 20 schizotypal personality disorder patients. Statistically significant differences (p <0,005 in neurocognitive function (regulatory processes, memory, spatial function between the healthy controls and patients with personality disorders were observed. Specific cognitive disorders pointing to the dysfunction of front-thalamoparietal connections were characteristic of both groups. Lateral differences were discovered for both patient groups. The

    2016-01-01

    Psychometric schizotypy in the general population correlates negatively with face recognition accuracy, potentially due to deficits in inhibition, social withdrawal, or eye-movement abnormalities. We report an eye-tracking face recognition study in which participants were required to match one of two faces (target and distractor) to a cue face presented immediately before. All faces could be presented with or without paraphernalia (e.g., hats, glasses, facial hair). Results showed that paraphernalia distracted participants, and that the most distracting condition was when the cue and the distractor face had paraphernalia but the target face did not, while there was no correlation between distractibility and participants' scores on the Schizotypal Personality Questionnaire (SPQ). Schizotypy was negatively correlated with proportion of time fixating on the eyes and positively correlated with not fixating on a feature. It was negatively correlated with scan path length and this variable correlated with face recognition accuracy. These results are interpreted as schizotypal traits being associated with a restricted scan path leading to face recognition deficits.

    1997-01-01

    Evidence shows a high comorbidity of eating disorders and some forms of personality disorder. Adopting a dimensional approach to both, our study explored their connection among a non-clinical sample. 191 young women completed personality scales of general neuroticism, and of borderline, schizotypal, obsessive-compulsive, and narcissistic (both adjustive and maladaptive) traits. Weight preoccupation (WP), as a normal analogue of eating disorders, was assessed with scales from the Eating Disorder Inventory, and height and weight measured. The data were analysed with multiple regression techniques, with WP as the dependent variable. In low to normal weight subjects, after controlling for the significant influence of body mass, the specific predictors of WP in the regression model were borderline personality and maladaptive narcissism, in the positive direction, and adjustive narcissism and obsessive-compulsiveness in the negative direction. In heavier women, narcissism made no contribution--nor, more significantly, did body mass. Patterns of association between eating pathology and personality disorder, especially borderline and narcissism, can be clearly mapped across to personality traits in the currently non-clinical population. This finding has important implications for understanding dynamics of, and identifying individuals at risk for, eating disorders.

    This study assessed the prevalence of personality disorders (PDs), according to DSM-IV criteria, in relation to depressive symptomatology at three different periods of life in female subjects. Depressive symptoms and personality disorders were assessed in a sample of 568 women from three different transitional stages: 134 students, 314 primiparous women after childbirth and 120 women diagnosed with breast cancer. Depressive symptoms were assessed by the Hospital Depression and Anxiety Scale in the first and third groups and by the Edinburgh Post-natal Depression Scale in the second group, whereas PDs were assessed by the French version of the Vragenlijst voor Kenmerken van de Persoonlijkheid. Depressive symptomatology and rates of PD (20.4% and 6.3%) were equivalent in the three groups. The prevalence of PD was higher in the depressed group compared with the non-depressed group, with more paranoid, borderline, avoidant, obsessive-compulsive, schizotypal, antisocial, dependent and histrionic PD. Our findings support the hypothesis that PDs are more frequently associated with depressive symptoms. Borderline and avoidant PDs were more prevalent among young women. All cluster C PD (dependent, avoidant and obsessive-compulsive) co-occurred significantly with depressive symptoms. Copyright © 2013 John Wiley & Sons, Ltd.

  2. Gravo-Aeroelastic Scaling for Extreme-Scale Wind Turbines

    A scaling methodology is described in the present paper for extreme-scale wind turbines (rated at 10 MW or more) that allow their sub-scale turbines to capture their key blade dynamics and aeroelastic deflections. For extreme-scale turbines, such deflections and dynamics can be substantial and are primarily driven by centrifugal, thrust and gravity forces as well as the net torque. Each of these are in turn a function of various wind conditions, including turbulence levels that cause shear, veer, and gust loads. The 13.2 MW rated SNL100-03 rotor design, having a blade length of 100-meters, is herein scaled to the CART3 wind turbine at NREL using 25% geometric scaling and blade mass and wind speed scaled by gravo-aeroelastic constraints. In order to mimic the ultralight structure on the advanced concept extreme-scale design the scaling results indicate that the gravo-aeroelastically scaled blades for the CART3 are be three times lighter and 25% longer than the current CART3 blades. A benefit of this scaling approach is that the scaled wind speeds needed for testing are reduced (in this case by a factor of two), allowing testing under extreme gust conditions to be much more easily achieved. Most importantly, this scaling approach can investigate extreme-scale concepts including dynamic behaviors and aeroelastic deflections (including flutter) at an extremely small fraction of the full-scale cost.

  3. Is Hinduism ambivalent about suicide?

    2018-05-01

    Hinduism is one of the oldest religions in the world and has over 1.1 billion adherents comprising about 16% of the global population living mainly in India and Nepal. The stand of Hinduism on suicide has been ambiguous through the ages, on one hand, condemning general suicides, while condoning religious suicides on the other. This ambiguity is reflected in contemporary India and among the Indian diaspora. To examine the stand of Hinduism as a religion in the context of suicide. A selected review of literature covering the major Hindu religious texts, cultural practices and suicide. People who follow Hinduism have a suicide rate of about 21 per 100,000 population compared to the global average of 11.4. Hindu countries have higher rates of suicide compared to Islamic and Christian countries, but these rates are lower when compared to Atheist and Buddhist countries. This is reflected in the Indian diaspora as well with reports from Fiji, the Caribbean, Malaysia and the United Kingdom, indicating that suicide was disproportionately high among those of Indian origin. However, a strong faith in Hinduism acts as protective factor. The Hindu belief in karma fosters a sense of acceptance of the vicissitudes of life with equanimity, and the belief in the cycle of births and deaths renders suicide meaningless, as one's soul continues after death. Their religious beliefs makes the Hindus tolerate and accept hardships and calamities stoically. In certain situations, the Hindu religion acts as a protective factor, whereas at other times, it may increase the risk of suicide. It is important to understand these different nuances in the Hindu religion in formulating a culturally appropriate suicide prevention strategy.

    To address the recognized low rates of breastfeeding in the United Kingdom (UK), a change in fundamental attitudes toward infant feeding might be required. This paper reports an exploration of women's attitudes toward breastfeeding at different time points in the perinatal period, undertaken as part of a larger breastfeeding evaluation study. To measure women's infant feeding attitudes at 3 stages during the perinatal period to see whether, on average, they differed over time. Using the 17-item Iowa Infant Feeding Attitudes Scale (IIFAS), this cross-sectional study measured the infant feeding attitudes of 866 UK women at 3 perinatal stages (20 and 35 weeks antenatally and 6 weeks postpartum). Mean IIFAS scores were very similar, which shows that discrete groups of women at different time points in pregnancy and postpartum appear to have the same attitudes toward infant feeding. The predominance of scores lay in the mid-range at each of the time points, which may indicate women's indecision or ambivalent feelings about infant feeding during pregnancy and the postpartum period. Action must be undertaken to target the majority of women with mid-range scores whose ambivalence may respond positively to intervention programs. The challenge is to understand what would be appropriate and acceptable to this vulnerable group of women.

  6. Scaling of Metabolic Scaling within Physical Limits

    Directory of Open Access Journals (Sweden)

    Douglas S. Glazier

    2014-10-01

    Full Text Available Both the slope and elevation of scaling relationships between log metabolic rate and log body size vary taxonomically and in relation to physiological or developmental state, ecological lifestyle and environmental conditions. Here I discuss how the recently proposed metabolic-level boundaries hypothesis (MLBH provides a useful conceptual framework for explaining and predicting much, but not all of this variation. This hypothesis is based on three major assumptions: (1 various processes related to body volume and surface area exert state-dependent effects on the scaling slope for metabolic rate in relation to body mass; (2 the elevation and slope of metabolic scaling relationships are linked; and (3 both intrinsic (anatomical, biochemical and physiological and extrinsic (ecological factors can affect metabolic scaling. According to the MLBH, the diversity of metabolic scaling relationships occurs within physical boundary limits related to body volume and surface area. Within these limits, specific metabolic scaling slopes can be predicted from the metabolic level (or scaling elevation of a species or group of species. In essence, metabolic scaling itself scales with metabolic level, which is in turn contingent on various intrinsic and extrinsic conditions operating in physiological or evolutionary time. The MLBH represents a “meta-mechanism” or collection of multiple, specific mechanisms that have contingent, state-dependent effects. As such, the MLBH is Darwinian in approach (the theory of natural selection is also meta-mechanistic, in contrast to currently influential metabolic scaling theory that is Newtonian in approach (i.e., based on unitary deterministic laws. Furthermore, the MLBH can be viewed as part of a more general theory that includes other mechanisms that may also affect metabolic scaling.

    This study explores the relative contribution of the overall quality of attachment to the mother, to the father and to peers (Inventory of Parent and Peer Attachment scales), the style of attachment towards peers (Attachment Questionnaire for Children scale), the social rank variables (submissive behavior and social comparison), and sex and age variables in predicting the depression score (Center of Epidemiological Studies Depression Scale) on a non-psychiatric sample of 13-18 year old adolescents (n = 225). Results of our integrated model (adjusted R-Square of .50) show that attachment variables (overall quality of attachment to the father and to the mother), social rank variables (social comparison and submissive behavior), age and sex are important in predicting depressive symptoms during adolescence. Moreover, the attachment to peers variables (quality of attachment to peers, secure and ambivalent style of attachment) and sex are mediated by the social rank variables (social comparison and submissive behavior).

  10. Analyzing the proximity to cover in a landscape of fear: a new approach applied to fine-scale habitat use by rabbits facing feral cat predation on Kerguelen archipelago

    Directory of Open Access Journals (Sweden)

    Pierrick Blanchard

    2016-03-01

    Full Text Available Although proximity to cover has been routinely considered as an explanatory variable in studies investigating prey behavioral adjustments to predation pressure, the way it shapes risk perception still remains equivocal. This paradox arises from both the ambivalent nature of cover as potentially both obstructive and protective, making its impact on risk perception complex and context-dependent, and from the choice of the proxy used to measure proximity to cover in the field, which leads to an incomplete picture of the landscape of fear experienced by the prey. Here, we study a simple predator-prey-habitat system, i.e., rabbits Oryctolagus cuniculus facing feral cat Felis catus predation on Kerguelen archipelago. We assess how cover shapes risk perception in prey and develop an easily implementable field method to improve the estimation of proximity to cover. In contrast to protocols considering the “distance to nearest cover”, we focus on the overall “area to cover”. We show that fine-scale habitat use by rabbits is clearly related to our measure, in accordance with our hypothesis of higher risk in patches with smaller area to cover in this predator-prey-habitat system. In contrast, classical measures of proximity to cover are not retained in the best predictive models of habitat use. The use of this new approach, together with a more in-depth consideration of contrasting properties of cover, could help to better understand the role of this complex yet decisive parameter for predator-prey ecology.

  11. Scaling up: Assessing social impacts at the macro-scale

    International Nuclear Information System (INIS)

    Schirmer, Jacki

    2011-01-01

    Social impacts occur at various scales, from the micro-scale of the individual to the macro-scale of the community. Identifying the macro-scale social changes that results from an impacting event is a common goal of social impact assessment (SIA), but is challenging as multiple factors simultaneously influence social trends at any given time, and there are usually only a small number of cases available for examination. While some methods have been proposed for establishing the contribution of an impacting event to macro-scale social change, they remain relatively untested. This paper critically reviews methods recommended to assess macro-scale social impacts, and proposes and demonstrates a new approach. The 'scaling up' method involves developing a chain of logic linking change at the individual/site scale to the community scale. It enables a more problematised assessment of the likely contribution of an impacting event to macro-scale social change than previous approaches. The use of this approach in a recent study of change in dairy farming in south east Australia is described.

  12. Phenomenological Psychopathology: From Spatial Disorder to the Problem of Disembodied Desire

    Directory of Open Access Journals (Sweden)

    Daria Dibitonto

    2014-12-01

    Full Text Available This study presents a phenomenological analysis of a case of schizotypal personality disorder used as a concrete starting point to formulate a basic phenomenological theory of embodied and disembodied desire. After describing the core symptoms of the patient (i.e. mainly his spatial disorder from a first-person per-spective, the problem of disembodied desire is introduced in relation to patient’s imaginary that is lived as an isolated experience condemned to remaining unrealized. The case analysis refers to Blankenburg’s concept of the loss of natural self-experience and to its contemporary development, i.e., the psychopathology of common sense, conceiving schizophrenia, and schizotypal personality disorder, as a syndrome rooted in ipseity disturbance and in disembodiment of the self. Disembodied desire is then qualified as a disorder due not to neurotic defense mechanisms, but rather to more pervasive self-disorders. In the final part, the problem of disembodied desire is addressed starting from a basic phenomenological theory of desire, dealing both with drive intentionality, as the transcendental condition of the ego-constitution, and with imagination, as the distanced self-representation of drive and as a structural possibility of distancing the immediacy of bodily experience.

    2018-02-15

    This study looked at lay theories of how people with sub-clinical personality disorders experience the world of work. The aim was to investigate the paradox that subclinical and clinical personality disorders are seen as beneficial for success, rather than a handicap in certain jobs. In all, 230 participants read 14 vignettes derived from Oldham and Morris's book describing DSMIII personality disorders for a popular audience. Participants were invited to suggest what type of work each disordered person may be successful at, as well as six ratings of their social adjustment. There was a tendency for people to believe those with OCD to be suited to Accountancy, Narcissism and Paranoia to General Management, Histrionic PD to being an Actor and Schizotypal an Artist. Surprisingly Paranoid and Sadistic people were judged to be good managers and Histrionic, Passive Aggressive and Schizotypal the worst. People in Cluster C were judged as best managers, but those in Cluster B as better adjusted. Results show that lay people believe that certain "dark-side" traits associated with personality disorders, particularly dependency and OCD, are thought to be beneficial for success, rather than failure, in many jobs.

  14. Scales and scaling in turbulent ocean sciences; physics-biology coupling

    Science.gov (United States)

    Schmitt, Francois

    2015-04-01

    Geophysical fields possess huge fluctuations over many spatial and temporal scales. In the ocean, such property at smaller scales is closely linked to marine turbulence. The velocity field is varying from large scales to the Kolmogorov scale (mm) and scalar fields from large scales to the Batchelor scale, which is often much smaller. As a consequence, it is not always simple to determine at which scale a process should be considered. The scale question is hence fundamental in marine sciences, especially when dealing with physics-biology coupling. For example, marine dynamical models have typically a grid size of hundred meters or more, which is more than 105 times larger than the smallest turbulence scales (Kolmogorov scale). Such scale is fine for the dynamics of a whale (around 100 m) but for a fish larvae (1 cm) or a copepod (1 mm) a description at smaller scales is needed, due to the nonlinear nature of turbulence. The same is verified also for biogeochemical fields such as passive and actives tracers (oxygen, fluorescence, nutrients, pH, turbidity, temperature, salinity...) In this framework, we will discuss the scale problem in turbulence modeling in the ocean, and the relation of Kolmogorov's and Batchelor's scales of turbulence in the ocean, with the size of marine animals. We will also consider scaling laws for organism-particle Reynolds numbers (from whales to bacteria), and possible scaling laws for organism's accelerations.

  16. Exploring intergenerational relations in a multi-cultural context: the example of filial responsibility in Mauritius.

    Hillcoat-Nallétamby, Sarah

    2010-03-01

    The purpose of this study is to explore attitudes towards filial responsibility amongst dyads of parents and young adult children using qualitative data from Mauritius, and to draw on the intergenerational solidarity-conflict and ambivalence frameworks to see whether they provide relevant interpretive tools for understanding these attitudes in a multi-cultural society. The study shows that although both generations agree that younger kin should support parents in later life, their motives vary: parents' attitudes reflect norms of obligation, children those of reciprocity; parents want autonomy and independence, but are ambivalent about expectations of future support. Both generations think providing support will be mediated by past parent-child relationships, socialization experiences, gender expectations and cultural tradition. The study suggests that attitudes towards filial responsibility are influenced by a broad set of mechanisms, which can be equated with concepts of structure, function, association, consensus and norm, as well as conflict and ambivalence.

    Full Text Available This study will examine postcolonial powers of opposition in Octavia Butler’s Kindred (1979; through Homi Bhabha’s concept of ambivalence and Edward Said’s self-other relationship. By using these concepts, this research aims to unravel how the colonized and the colonizer perceive each in the selected works. It will offer an in-depth analysis of the thematic and ideological characteristics of selected works. Thus, the focus will mainly be on the theme of the mutual relationship between the colonized and the colonizer in the selected works. This relationship is specified to the concept of ambivalence. This concept incarnates the dual, yet, uncontrolled relationship between the colonized and the colonizer. Nevertheless, the colonized considers the colonizer as oppressive but an envious power; and the colonizer judges the colonized as inferior but indigenous. The colonial relationship will also be revealed by using the concept of self-other. Such concept scrutinizes the way the colonized and the colonizer perceive and resist each other. Accordingly, the research’s main focus point is the power relationship developed in the light of colonial ambivalence and self-other continuum. The research’s methodology relies on Bhabha’s concept of ambivalence and Edward Said’s self-other relationship.  In The Location of Culture (1994, Bhabha maintains that the concept of ambivalence conveys “the exercise of colonialist authority, however, requires the production of differentiations, individuations, identity effects through which discriminatory practices can map out subject populations that are tarred with the visible and transparent mark of power” (111. Edward Said, in his discussion of self-other relationship in Orientalism (1979, argues that self-other relationship is “the vacillation [inconstancy] between the familiar [self] and the alien [other]” (72.

    Full Text Available Starting from a reconstruction of the origins of the concept of “modernity” in the late Nineteenth century and of the different interpretations of it in the context of the German social sciences, the essay articulates its radical ambivalences. After establishing that modernity cannot be measured on a scale of progress, neither can it be identified with a specific value, Christof Dipper suggests that there are many conceptions of modernity as there are societies, and that these are not necessarily following a common path. The concept of modernity, that includes anti-modernity as well, embraces therefore actors, representations, and constellations, offering an overall reading of history.

    1999-08-01

    This study examined the relationship between self-image and ethnic identification among 3 South African groups. Participants included random samples of 347 Afrikaans-speaking Whites, 113 English-speaking Whites, and 466 Blacks in urban Gauteng. Positive and negative self-image were extracted using the Rosenberg Self-Esteem Scale (M. Rosenberg, 1965). Afrikaans-speaking Whites had the most positive self-image and Blacks the most negative self-image. A positive self-image was correlated with stronger ethnic identification among Afrikaans-speaking Whites. The opposite was true for Blacks. This relationship was insignificant among English-speaking Whites. Ambivalence toward ingroup identity was persistently correlated with self-image for all groups.

    Diverse biological networks exhibit universal features distinguished from those of random networks, calling much attention to their origins and implications. Here we propose a minimal evolution model of Boolean regulatory networks, which evolve by selectively rewiring links towards enhancing adaptability to a changing environment and stability against dynamical perturbations. We find that sparse and heterogeneous connectivity patterns emerge, which show qualitative agreement with real transcriptional regulatory networks and metabolic networks. The characteristic scaling behavior of stability reflects the balance between robustness and flexibility. The scaling of fluctuation in the perturbation spread shows a dynamic crossover, which is analyzed by investigating separately the stochasticity of internal dynamics and the network structure differences depending on the evolution pathways. Our study delineates how the ambivalent pressure of evolution shapes biological networks, which can be helpful for studying general complex systems interacting with environments.

  2. Energy transfers in large-scale and small-scale dynamos

    Samtaney, Ravi; Kumar, Rohit; Verma, Mahendra

    2015-11-01

    We present the energy transfers, mainly energy fluxes and shell-to-shell energy transfers in small-scale dynamo (SSD) and large-scale dynamo (LSD) using numerical simulations of MHD turbulence for Pm = 20 (SSD) and for Pm = 0.2 on 10243 grid. For SSD, we demonstrate that the magnetic energy growth is caused by nonlocal energy transfers from the large-scale or forcing-scale velocity field to small-scale magnetic field. The peak of these energy transfers move towards lower wavenumbers as dynamo evolves, which is the reason for the growth of the magnetic fields at the large scales. The energy transfers U2U (velocity to velocity) and B2B (magnetic to magnetic) are forward and local. For LSD, we show that the magnetic energy growth takes place via energy transfers from large-scale velocity field to large-scale magnetic field. We observe forward U2U and B2B energy flux, similar to SSD.

    2017-12-01

    This article dialogues with Matthew Weinstein's paper named "NGSS, disposability, and the ambivalence of Science in/under neoliberalism", in which he explores the argument that at the same time the NGSS framework is largely identified with neoliberal discourse, it presents points of ambivalence and resistance within. In this dialogue, we focused on two topics that we believe are important for the discussion of the ambivalences highlighted in the author's argument, namely: the the social production of indifference as a consequence of the neoliberal ideology and the production of a version of science streamlined for the neoliberal technoscientific job market within the `neoliberal ecosystem'. Based on the thesis of the Canadian philosopher Charles Taylor on ethics and on the concept of hybridism, we linked Weinsteins' analysis to issues related to individualism and instrumental reason, pointing out that it is possible that the ambivalences highlighted by Weinstein are, in fact, a component of neoliberal discourse. Nevertheless we agree that this kind of text presents loopholes that allows practices oriented for social change and for the improvement of democracies in progress. We conclude that for those who dedicate themselves to reflect upon educational strategies to cope with the hegemonic model remains the challenge of finding spaces and times in the curriculum in order to explore the gaps in policy texts and, more important, to promote the experience of democratic practices throughout the school communities.

  4. A multi scale model for small scale plasticity

    2002-01-01

    Full text.A framework for investigating size-dependent small-scale plasticity phenomena and related material instabilities at various length scales ranging from the nano-microscale to the mesoscale is presented. The model is based on fundamental physical laws that govern dislocation motion and their interaction with various defects and interfaces. Particularly, a multi-scale model is developed merging two scales, the nano-microscale where plasticity is determined by explicit three-dimensional dislocation dynamics analysis providing the material length-scale, and the continuum scale where energy transport is based on basic continuum mechanics laws. The result is a hybrid simulation model coupling discrete dislocation dynamics with finite element analyses. With this hybrid approach, one can address complex size-dependent problems, including dislocation boundaries, dislocations in heterogeneous structures, dislocation interaction with interfaces and associated shape changes and lattice rotations, as well as deformation in nano-structured materials, localized deformation and shear band

    2011-07-01

    This study included two different methods to assess mother-child attachment, questionnaires, and a doll play story stem interview, so their overlap could be evaluated. In addition, we investigated how attachment is related to parenting and child depression. The sample was comprised of 10- to 12-year-olds (N = 87) and their mothers. Children completed questionnaires (assessing security, avoidance, and ambivalence), and were administered a doll play interview to assess attachment patterns (security, avoidance, ambivalence, and disorganization). Two aspects of parenting (warmth/ engagement and psychological control) were assessed with child reports and observer ratings of maternal behavior. We also obtained child reports of depressive symptoms. Questionnaire and interview measures of attachment security were related to one another, and each showed predictable associations with parenting and child depression. By contrast, results were less consistent for the ambivalent and avoidant insecure attachment patterns, although disorganized attachment showed some associations with parenting and child adjustment.

    To what extent are attachment styles manifested in natural social activity? A total of 125 participants categorized as possessing secure, avoidant, or anxious-ambivalent attachment styles kept structured social interaction diaries for 1 week. Several theoretically important findings emerged. First, compared with secure and anxious-ambivalent persons, avoidant persons reported lower levels of intimacy, enjoyment, promotive interaction, and positive emotions, and higher levels of negative emotions, primarily in opposite-sex interactions. Analyses indicated that avoidant persons may structure social activities in ways that minimize closeness. Second, secure people differentiated more clearly than either insecure group between romantic and other opposite-sex partners. Third, the subjective experiences of anxious-ambivalent persons were more variable than those of the other groups. Finally, the authors examined and rejected the possibility that attachment effects might be confounded with physical attractiveness. These findings suggest that feeling and behaviors that arise during spontaneous, everyday social activity may contribute to the maintenance of attachment styles in adulthood.

    Stereotypical sexist representations of men and women in popular culture reinforce rigid views of masculinity (e.g., males as being strong, in control, masterful, and aggressive) and femininity (e.g., women as being fragile and weak, unassertive, peaceful, irrational, and driven by emotions). The present study examined associations between the fictional series Fifty Shades-one popular culture mechanism that includes pervasive traditional gender role representations-and underlying sexist beliefs among a sample of 715 women ages 18-24 years. Analyses revealed associations between Fifty Shades readership and sexism, as measured through the Ambivalent Sexism Inventory. Namely women who reported reading Fifty Shades had higher levels of ambivalent, benevolent, and hostile sexism. Further, those who interpreted Fifty Shades as "romantic" had higher levels of ambivalent and benevolent sexism. Our findings support prior empirical studies noting associations between interacting with aspects of popular culture, such as television and video games, and individual beliefs and behaviors.

  11. Optimal renormalization scales and commensurate scale relations

    International Nuclear Information System (INIS)

    Brodsky, S.J.; Lu, H.J.

    1996-01-01

    Commensurate scale relations relate observables to observables and thus are independent of theoretical conventions, such as the choice of intermediate renormalization scheme. The physical quantities are related at commensurate scales which satisfy a transitivity rule which ensures that predictions are independent of the choice of an intermediate renormalization scheme. QCD can thus be tested in a new and precise way by checking that the observables track both in their relative normalization and in their commensurate scale dependence. For example, the radiative corrections to the Bjorken sum rule at a given momentum transfer Q can be predicted from measurements of the e+e - annihilation cross section at a corresponding commensurate energy scale √s ∝ Q, thus generalizing Crewther's relation to non-conformal QCD. The coefficients that appear in this perturbative expansion take the form of a simple geometric series and thus have no renormalon divergent behavior. The authors also discuss scale-fixed relations between the threshold corrections to the heavy quark production cross section in e+e - annihilation and the heavy quark coupling α V which is measurable in lattice gauge theory

  12. Why small-scale cannabis growers stay small: five mechanisms that prevent small-scale growers from going large scale.

    Hammersvik, Eirik; Sandberg, Sveinung; Pedersen, Willy

    2012-11-01

    Over the past 15-20 years, domestic cultivation of cannabis has been established in a number of European countries. New techniques have made such cultivation easier; however, the bulk of growers remain small-scale. In this study, we explore the factors that prevent small-scale growers from increasing their production. The study is based on 1 year of ethnographic fieldwork and qualitative interviews conducted with 45 Norwegian cannabis growers, 10 of whom were growing on a large-scale and 35 on a small-scale. The study identifies five mechanisms that prevent small-scale indoor growers from going large-scale. First, large-scale operations involve a number of people, large sums of money, a high work-load and a high risk of detection, and thus demand a higher level of organizational skills than for small growing operations. Second, financial assets are needed to start a large 'grow-site'. Housing rent, electricity, equipment and nutrients are expensive. Third, to be able to sell large quantities of cannabis, growers need access to an illegal distribution network and knowledge of how to act according to black market norms and structures. Fourth, large-scale operations require advanced horticultural skills to maximize yield and quality, which demands greater skills and knowledge than does small-scale cultivation. Fifth, small-scale growers are often embedded in the 'cannabis culture', which emphasizes anti-commercialism, anti-violence and ecological and community values. Hence, starting up large-scale production will imply having to renegotiate or abandon these values. Going from small- to large-scale cannabis production is a demanding task-ideologically, technically, economically and personally. The many obstacles that small-scale growers face and the lack of interest and motivation for going large-scale suggest that the risk of a 'slippery slope' from small-scale to large-scale growing is limited. Possible political implications of the findings are discussed. Copyright

  13. Multi-Scale Models for the Scale Interaction of Organized Tropical Convection

    Science.gov (United States)

    Yang, Qiu

    Assessing the upscale impact of organized tropical convection from small spatial and temporal scales is a research imperative, not only for having a better understanding of the multi-scale structures of dynamical and convective fields in the tropics, but also for eventually helping in the design of new parameterization strategies to improve the next-generation global climate models. Here self-consistent multi-scale models are derived systematically by following the multi-scale asymptotic methods and used to describe the hierarchical structures of tropical atmospheric flows. The advantages of using these multi-scale models lie in isolating the essential components of multi-scale interaction and providing assessment of the upscale impact of the small-scale fluctuations onto the large-scale mean flow through eddy flux divergences of momentum and temperature in a transparent fashion. Specifically, this thesis includes three research projects about multi-scale interaction of organized tropical convection, involving tropical flows at different scaling regimes and utilizing different multi-scale models correspondingly. Inspired by the observed variability of tropical convection on multiple temporal scales, including daily and intraseasonal time scales, the goal of the first project is to assess the intraseasonal impact of the diurnal cycle on the planetary-scale circulation such as the Hadley cell. As an extension of the first project, the goal of the second project is to assess the intraseasonal impact of the diurnal cycle over the Maritime Continent on the Madden-Julian Oscillation. In the third project, the goals are to simulate the baroclinic aspects of the ITCZ breakdown and assess its upscale impact on the planetary-scale circulation over the eastern Pacific. These simple multi-scale models should be useful to understand the scale interaction of organized tropical convection and help improve the parameterization of unresolved processes in global climate models.

  14. Scale-by-scale contributions to Lagrangian particle acceleration

    Lalescu, Cristian C.; Wilczek, Michael

    2017-11-01

    Fluctuations on a wide range of scales in both space and time are characteristic of turbulence. Lagrangian particles, advected by the flow, probe these fluctuations along their trajectories. In an effort to isolate the influence of the different scales on Lagrangian statistics, we employ direct numerical simulations (DNS) combined with a filtering approach. Specifically, we study the acceleration statistics of tracers advected in filtered fields to characterize the smallest temporal scales of the flow. Emphasis is put on the acceleration variance as a function of filter scale, along with the scaling properties of the relevant terms of the Navier-Stokes equations. We furthermore discuss scaling ranges for higher-order moments of the tracer acceleration, as well as the influence of the choice of filter on the results. Starting from the Lagrangian tracer acceleration as the short time limit of the Lagrangian velocity increment, we also quantify the influence of filtering on Lagrangian intermittency. Our work complements existing experimental results on intermittency and accelerations of finite-sized, neutrally-buoyant particles: for the passive tracers used in our DNS, feedback effects are neglected such that the spatial averaging effect is cleanly isolated.

    Japan often pictures itself as an environmental leader. While many examples of Japan's actions against climate change are in line with global climate change norms, others can be in opposition to them. This study, based on first hand interviews with Japanese policy makers and actors from the private and civil society sector, gives an informed perspective on the process through which Japan came to integrate and implement, at the domestic level, the international objective of climate change prevention, pointing out the discrepancies, tensions or synergies that emerged. As the current governance on climate change, and particularly after the Copenhagen conference, tends to reassert the importance of the national level against the global one, the Japanese case can serve as an example of tools and strategies that fully integrate the domestic level

    Medical educators invoke professionalism as a core competency in curricula. This paper criticizes classic definitions. It also identifies some negative traits of medicine as a profession. The call to professionalism is naive nostalgia. Straightforward didactics in professionalism cannot do the desired work in medical education. The most we can say is that students should adopt the good aspects of professionalism and the profession should stop being some of what it has been. This is a platitude. If the notion is to be more than shallow, each student and practitioner will have to engage in much dialogue, reflection and refinement over many years.

    Spiritual well-being (SpWB) is integral to health-related quality of life. The challenges of colorectal cancer (CRC) and subsequent bodily changes can affect SpWB. We analyzed the SpWB of CRC survivors with ostomies. Two-hundred-eighty-three long-term (≥ 5 years) CRC survivors with permanent ostomies completed the modified City of Hope Quality of Life-Ostomy (mCOH-QOL-O) questionnaire. An open-ended question elicited respondents' greatest challenge in living with an ostomy. We used content analysis to identify SpWB responses and develop themes. We analyzed responses on the three-item SpWB sub-scale. Open-ended responses from 52% of participants contained SpWB content. Fifteen unique SpWB themes were identified. Sixty percent of individuals expressed positive themes such as "positive attitude", "I am fortunate", "appreciate life more", and "strength through religious faith". Negative themes, expressed by only 29% of respondents, included "struggling to cope", "not feeling 'normal' ", and "loss". Fifty-five percent of respondents expressed ambivalent themes including "learning acceptance", "an ostomy is the price for survival", "reason to be around despite suffering", and "continuing to cope despite challenges". The majority (64%) had a high SpWB sub-scale score. Although CRC survivors with ostomies infrequently mentioned negative SpWB themes as a major challenge, ambivalent themes were common. SpWB themes were often mentioned as a source of resilience or part of the struggle to adapt to an altered body after cancer surgery. Interventions to improve the quality of life of cancer survivors should contain program elements designed to address SpWB that support personal meaning, inner peace, inter connectedness, and belonging.

Through the depiction of four intensifications of Lean Production, the metaphors of Calvino's cities show how reality and illusion; hope and poverty; dreams and death and utopia and dystopia are intricately mingled and produce temporary and equally ambivalent affects of alienation, hypocrisy, self...

    Objective In the present study the relationship between behavioural adjustment following cognitive conflict and schizotypy was investigated using a Stroop colour naming paradigm. Previous research has found deficits with behavioural adjustment in schizophrenia patients. Based on these findings, we hypothesized that individual differences in schizotypy, a personality trait reflecting the subclinical expression of the schizophrenia phenotype, would be associated with behavioural adjustment. Additionally, we investigated whether such a relationship would be explained by individual differences in neuroticism, a non-specific measure of negative trait emotionality known to be correlated with schizotypy. Methods 106 healthy volunteers (mean age: 25.1, 60% females) took part. Post-conflict adjustment was measured in a computer-based version of the Stroop paradigm. Schizotypy was assessed using the Schizotypal Personality Questionnaire (SPQ) and Neuroticism using the NEO-FFI. Results We found a negative correlation between schizotypy and post-conflict adjustment (r = −.30, p<.01); this relationship remained significant when controlling for effects of neuroticism. Regression analysis revealed that particularly the subscale No Close Friends drove the effect. Conclusion Previous findings of deficits in cognitive control in schizophrenia patients were extended to the subclinical personality expression of the schizophrenia phenotype and found to be specific to schizotypal traits over and above the effects of negative emotionality.

    The purpose of this article is to review recent literature examining the occurrence of psychotic experiences in normal population and those with personality disorders. Up to 15% of individuals in the general population report some type or degree of psychotic experience. Most of these individuals function adequately, do not require psychiatric treatment and do not receive diagnosis of a psychotic illness. A significant number of individuals diagnosed with borderline personality disorder (25-50%) also report psychotic symptoms. These are not easily differentiated from the psychotic symptoms reported by individuals with schizophrenia, nor are they always transient. However, emerging research has confirmed that individuals with schizotypal personality disorder are dimensionally related to those with schizophrenia and are at an increased risk of transition to psychosis. Psychotic symptoms are best considered as 'trans-diagnostic' entities on a continuum from normal to pathological. There is a large body of evidence for a dimensional relationship between schizotypal personality disorder and schizophrenia. There is also a significant amount of research showing that psychotic symptoms in borderline personality disorder are frequent, nontransient and represent a marker of illness severity. This review highlights the need to move beyond traditional assumptions and categorical boundaries when evaluating psychotic experiences and psychopathological phenomena.

    Full Text Available Objective: To assess the relationship of biological rhythms, evaluated by the Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN, with affective temperaments and schizotypy. Methods: The BRIAN assessment, along with the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A and the Oxford-Liverpool Inventory for Feelings and Experiences (O-LIFE, was administered to 54 patients with remitted bipolar disorder (BD and 54 healthy control (HC subjects. Results: The TEMPS-A cyclothymic temperament correlated positively and the hyperthymic temperament correlated negatively with BRIAN scores in both the BD and HC groups, although the correlation was stronger in BD subjects. Depressive temperament was associated with BRIAN scores in BD but not in HC; conversely, the irritable temperament was associated with BRIAN scores in HC, but not in BD. Several positive correlations between BRIAN scores and the schizotypal dimensions of the O-LIFE were observed in both BD and HC subjects, especially with cognitive disorganization and less so with unusual experiences and impulsive nonconformity. A correlation with introversion/anhedonia was found only in BD subjects. Conclusion: Cyclothymic and depressive temperaments predispose to disturbances of biological rhythms in BD, while a hyperthymic temperament can be protective. Similar predispositions were also found for all schizotypal dimensions, mostly for cognitive disorganization.

    Difficulties in understanding irony and sarcasm are part of the social cognition deficits in patients with schizophrenia. A number of studies have reported higher error rates during comprehension in patients with schizophrenia. However, the relationships of these impairments to schizotypal personality traits and other language deficits, such as the comprehension of proverbs, are unclear. We investigated irony and proverb comprehension in an all-female sample of 20 schizophrenia patients and 27 matched controls. Subjects indicated if a statement was intended to be ironic, literal, or meaningless and furthermore rated the meanness and funniness of the stimuli and certainty of their decision. Patients made significantly more errors than controls did. Globally, there were no overall differences in the ratings. However, patients rated the subgroup of stimuli with answers given incorrectly as having significantly less meanness and in case of an error indicated a significantly higher certainty than controls. Across all of the study participants, performances in irony (r = −0.51) and proverb (r = 0.56) comprehension were significantly correlated with schizotypal personality traits, suggesting a continuum of nonliteral language understanding. Because irony is so frequent in everyday conversations, this makes irony an especially promising candidate for social cognition training in schizophrenia. PMID:24991434

    Few typological studies address schizotypy in young adults. Schizotypal traits were assessed on 466 college students using the Schizotypal Personality Questionnaire-Brief (SPQ-B). Other measures evaluated personality traits previously associated with schizotypy (borderline, obsessionnal, and autistic traits), psychopathological symptoms (suicidal ideations, depressive and obsessive-compulsive symptoms) and psychosocial functioning. A factor analysis was first performed on SPQ-B results, leading to four factors: negative schizotypy, positive schizotypy, social anxiety, and reference ideas. Based on these factors, a cluster analysis was conducted, which yielded four clearly distinct groups characterized by "Low" (non schizotypy), "High schizotypy" (mixed positive and negative), "Positive schizotypy", and "Social impairment". Regarding personality disorder traits and psychopathological symptoms, the "High schizotypy" cluster scored higher than the "Positive" and the "Social impairment" groups, which scored higher than the "Low" cluster. The "Positive" group had higher levels of interpersonal relationships than in the "High" and the "Social impairment" clusters, suggesting that positive schizotypy was associated to benefits such as perceived social relationships. Nevertheless the "Positive" cluster was also linked to high levels of personality disorder traits and psychopathological symptoms, and to low academic achievement, at levels similar those observed in the "Social impairment" cluster, confirming an unhealthy side to positive schizotypy.

  15. Scaling Effects on Materials Tribology: From Macro to Micro Scale.

    Science.gov (United States)

    Stoyanov, Pantcho; Chromik, Richard R

    2017-05-18

    The tribological study of materials inherently involves the interaction of surface asperities at the micro to nanoscopic length scales. This is the case for large scale engineering applications with sliding contacts, where the real area of contact is made up of small contacting asperities that make up only a fraction of the apparent area of contact. This is why researchers have sought to create idealized experiments of single asperity contacts in the field of nanotribology. At the same time, small scale engineering structures known as micro- and nano-electromechanical systems (MEMS and NEMS) have been developed, where the apparent area of contact approaches the length scale of the asperities, meaning the real area of contact for these devices may be only a few asperities. This is essentially the field of microtribology, where the contact size and/or forces involved have pushed the nature of the interaction between two surfaces towards the regime where the scale of the interaction approaches that of the natural length scale of the features on the surface. This paper provides a review of microtribology with the purpose to understand how tribological processes are different at the smaller length scales compared to macrotribology. Studies of the interfacial phenomena at the macroscopic length scales (e.g., using in situ tribometry) will be discussed and correlated with new findings and methodologies at the micro-length scale.

    In situ bioremediation involves complex interactions between biological, chemical, and physical processes and requires integration of phenomena operating at scales ranging from that of a microbial cell (10 -6 ) to that of a remediation site (10 to 1000 m). Laboratory investigations of biodegradation are usually performed at a relatively small scale, governed by convenience, cost, and expedience. However, extending the results from a laboratory-scale experimental system to the design and operation of a field-scale system introduces (1) additional mass transport mechanisms and limitations; (2) the presence of multiple phases, contants, and competing microorganisms (3) spatial geologic heterogeneities; and (4) subsurface environmental factors that may inhibit bacterial growth such as temperature, pH, nutrient, or redox conditions. Field bioremediation rates may be limited by the availability of one of the necessary constituents for biotransformation: substrate, contaminant, electron acceptor, nutrients, or microorganisms capable of degrading the target compound. The factor that limits the rate of bioremediation may not be the same in the laboratory as it is in the field, thereby leading, to development of unsuccessful remediation strategies

    Ambivalent sexism has many pernicious consequences. Since gender stereotypes also affect leadership roles, the present research investigated the effects of ambivalent sexism on envisioning oneself as a leader. Our studies tested the influence of sexist attitudes (toward women – Study 1 – and men – Study 2) on leadership aspiration, taking into account the interaction among ambivalent attitudes, personal characteristics (e.g. self-esteem), and group processes (e.g. level of identification with gender). Specifically, the current study used a 3 (sexism: hostile, benevolent, control) x 2 (social identification: high, low) x 2 (self-esteem: high, low) factorial design. 178 women participated in Study 1. Results showed that, although sexism was not recognised as a form of prejudice and did not trigger negative emotions, in sexist conditions high-identified women increase their leadership aspiration. In Study 2 men (N = 184) showed to recognise hostility as a form of prejudice, to experience more negative emotions, but to be not influenced in leadership aspiration. For both men and women self-esteem had a significant main effect on leadership aspiration. PMID:27872665

    Social class stereotypes support inequality through various routes: ambivalent content, early appearance in children, achievement consequences, institutionalization in education, appearance in cross-class social encounters, and prevalence in the most unequal societies. Class-stereotype content is ambivalent, describing lower-SES people both negatively (less competent, less human, more objectified), and sometimes positively, perhaps warmer than upper-SES people. Children acquire the wealth aspects of class stereotypes early, which become more nuanced with development. In school, class stereotypes advantage higher-SES students, and educational contexts institutionalize social-class distinctions. Beyond school, well-intentioned face-to-face encounters ironically draw on stereotypes to reinforce the alleged competence of higher-status people and sometimes the alleged warmth of lower-status people. Countries with more inequality show more of these ambivalent stereotypes of both lower-SES and higher-SES people. At a variety of levels and life stages, social-class stereotypes reinforce inequality, but constructive contact can undermine them; future efforts need to address high-status privilege and to query more heterogeneous samples.

  1. The ontology of the maternal: A response to Adriana Cavarero

    Directory of Open Access Journals (Sweden)

    Alison Stone

    2010-01-01

    Full Text Available In this article I engage critically with the approach to mothering and the maternal adopted by the Italian feminist philosopher Adriana Cavarero in her recent work. Cavarero considers the maternal in relation to the human condition understood as a condition of natality and relationality. I suggest that this is an original and helpful approach, but I raise some critical questions. Asking how far Cavarero is faithful to Hannah Arendt, I suggest that her reading of Arendt is transformative. I then question Cavarero's apparent focus on the mothering of sons, rather than daughters. I ask whether, in seeking to re-value and re-interpret the maternal, Cavarero inadvertently reinforces the gender division of labour under which women generally remain the primary child-carers. Finally, I explore Cavarero's view that ambivalence is integral to mothering, as rooted in the human condition. Ultimately, Cavarero treats ambivalence as a possibility inherent in mothering, but one that the good mother does not allow herself to realise. Referring to Euripides' 'Medea', I appraise maternal ambivalence more positively.

    We investigate the scaling behavior of sample statistics of pore-scale Lagrangian velocities in two different rock samples, Bentheimer sandstone and Estaillades limestone. The samples are imaged using x-ray computer tomography with micron-scale resolution. The scaling analysis relies on the study of the way qth-order sample structure functions (statistical moments of order q of absolute increments) of Lagrangian velocities depend on separation distances, or lags, traveled along the mean flow direction. In the sandstone block, sample structure functions of all orders exhibit a power-law scaling within a clearly identifiable intermediate range of lags. Sample structure functions associated with the limestone block display two diverse power-law regimes, which we infer to be related to two overlapping spatially correlated structures. In both rocks and for all orders q, we observe linear relationships between logarithmic structure functions of successive orders at all lags (a phenomenon that is typically known as extended power scaling, or extended self-similarity). The scaling behavior of Lagrangian velocities is compared with the one exhibited by porosity and specific surface area, which constitute two key pore-scale geometric observables. The statistical scaling of the local velocity field reflects the behavior of these geometric observables, with the occurrence of power-law-scaling regimes within the same range of lags for sample structure functions of Lagrangian velocity, porosity, and specific surface area.

    Hydrogen production by water electrolysis represents nearly 4 % of the world hydrogen production. Future development of hydrogen vehicles will require large quantities of hydrogen. Installation of large scale hydrogen production plants will be needed. In this context, development of low cost large scale electrolysers that could use 'clean power' seems necessary. ALPHEA HYDROGEN, an European network and center of expertise on hydrogen and fuel cells, has performed for its members a study in 2005 to evaluate the potential of large scale electrolysers to produce hydrogen in the future. The different electrolysis technologies were compared. Then, a state of art of the electrolysis modules currently available was made. A review of the large scale electrolysis plants that have been installed in the world was also realized. The main projects related to large scale electrolysis were also listed. Economy of large scale electrolysers has been discussed. The influence of energy prices on the hydrogen production cost by large scale electrolysis was evaluated. (authors)

    To evaluated the differences in knowledge, adherence, attitudes, and beliefs about medicine in adolescents with inflammatory bowel disease (IBD) attending transition clinics. We prospectively enrolled patients from July 2012 to June 2013. All adolescents who attended a tertiary-centre-based dedicated IBD transition clinic were invited to participate. Adolescent controls were recruited from university-affiliated gastroenterology offices. Participants completed questionnaires about their disease and reported adherence to prescribed therapy. Beliefs in Medicine Questionnaire was used to evaluate patients' attitudes and beliefs. Beliefs of medication overuse, harm, necessity and concerns were rated on a Likert scale. Based on necessity and concern ratings, attitudes were then characterized as accepting, ambivalent, skeptical and indifferent. One hundred and twelve adolescents were included and 59 attended transition clinics. Self-reported adherence rates were poor, with only 67.4% and 56.8% of patients on any IBD medication were adherent in the transition and control groups, respectively. Adolescents in the transition cohort held significantly stronger beliefs that medications were necessary ( P = 0.0035). Approximately 20% of adolescents in both cohorts had accepting attitudes toward their prescribed medicine. However, compared to the control group, adolescents in the transition cohort were less skeptical of (6.8% vs 20.8%) and more ambivalent (61% vs 34%) (OR = 0.15; 95%CI: 0.03-0.75; P = 0.02) to treatment. Attendance at dedicated transition clinics was associated with differences in attitudes in adolescents with IBD.

  6. Scale-relativistic cosmology

    International Nuclear Information System (INIS)

    Nottale, Laurent

    2003-01-01

    The principle of relativity, when it is applied to scale transformations, leads to the suggestion of a generalization of fundamental dilations laws. These new special scale-relativistic resolution transformations involve log-Lorentz factors and lead to the occurrence of a minimal and of a maximal length-scale in nature, which are invariant under dilations. The minimal length-scale, that replaces the zero from the viewpoint of its physical properties, is identified with the Planck length l P , and the maximal scale, that replaces infinity, is identified with the cosmic scale L=Λ -1/2 , where Λ is the cosmological constant.The new interpretation of the Planck scale has several implications for the structure and history of the early Universe: we consider the questions of the origin, of the status of physical laws at very early times, of the horizon/causality problem and of fluctuations at recombination epoch.The new interpretation of the cosmic scale has consequences for our knowledge of the present universe, concerning in particular Mach's principle, the large number coincidence, the problem of the vacuum energy density, the nature and the value of the cosmological constant. The value (theoretically predicted ten years ago) of the scaled cosmological constant Ω Λ =0.75+/-0.15 is now supported by several different experiments (Hubble diagram of Supernovae, Boomerang measurements, gravitational lensing by clusters of galaxies).The scale-relativity framework also allows one to suggest a solution to the missing mass problem, and to make theoretical predictions of fundamental energy scales, thanks to the interpretation of new structures in scale space: fractal/classical transitions as Compton lengths, mass-coupling relations and critical value 4π 2 of inverse couplings. Among them, we find a structure at 3.27+/-0.26x10 20 eV, which agrees closely with the observed highest energy cosmic rays at 3.2+/-0.9x10 20 eV, and another at 5.3x10 -3 eV, which corresponds to the

  7. SCALE INTERACTION IN A MIXING LAYER. THE ROLE OF THE LARGE-SCALE GRADIENTS

    KAUST Repository

    Fiscaletti, Daniele

    2015-08-23

    The interaction between scales is investigated in a turbulent mixing layer. The large-scale amplitude modulation of the small scales already observed in other works depends on the crosswise location. Large-scale positive fluctuations correlate with a stronger activity of the small scales on the low speed-side of the mixing layer, and a reduced activity on the high speed-side. However, from physical considerations we would expect the scales to interact in a qualitatively similar way within the flow and across different turbulent flows. Therefore, instead of the large-scale fluctuations, the large-scale gradients modulation of the small scales has been additionally investigated.

  8. Scaling down

    2015-11-01

    Full Text Available While “scaling up” is a lively topic in network science and Big Data analysis today, my purpose in this essay is to articulate an alternative problem, that of “scaling down,” which I believe will also require increased attention in coming years. “Scaling down” is the problem of how macro-level features of Big Data affect, shape, and evoke lower-level features and processes. I identify four aspects of this problem: the extent to which findings from studies of Facebook and other Big-Data platforms apply to human behavior at the scale of church suppers and department politics where we spend much of our lives; the extent to which the mathematics of scaling might be consistent with behavioral principles, moving beyond a “universal” theory of networks to the study of variation within and between networks; and how a large social field, including its history and culture, shapes the typical representations, interactions, and strategies at local levels in a text or social network.

  9. Improving the coastal record of tsunamis in the ESI-07 scale: Tsunami Environmental Effects Scale (TEE-16 scale)

    This paper discusses possibilities to improve the Environmental Seismic Intensity Scale (ESI-07 scale), a scale based on the effects of earthquakes in the environment. This scale comprises twelve intensity degrees and considers primary and secondary effects, one of them the occurrence of tsunamis. Terminology and physical tsunami parameters corresponding to different intensity levels are often misleading and confusing. The present work proposes: i) a revised and updated catalogue of environmental and geological effects of tsunamis, gathering all the available information on Tsunami Environmental Effects (TEEs) produced by recent earthquake-tsunamis; ii) a specific intensity scale (TEE-16) for the effects of tsunamis in the natural environment at coastal areas. The proposed scale could be used in future tsunami events and, in historic and paleo-tsunami studies. The new TEE- 16 scale incorporates the size specific parameters already considered in the ESI-07 scale, such as wave height, run-up and inland extension of inundation, and a comprehensive and more accurate terminology that covers all the different intensity levels identifiable in the geological record (intensities VI-XII). The TEE-16 scale integrates the description and quantification of the potential sedimentary and erosional features (beach scours, transported boulders and classical tsunamites) derived from different tsunami events at diverse coastal environments (e.g. beaches, estuaries, rocky cliffs,). This new approach represents an innovative advance in relation to the tsunami descriptions provided by the ESI-07 scale, and allows the full application of the proposed scale in paleoseismological studies. The analysis of the revised and updated tsunami environmental damage suggests that local intensities recorded in coastal areas do not correlate well with the TEE-16 intensity (normally higher), but shows a good correlation with the earthquake magnitude (Mw). Tsunamis generated by earthquakes can then be

    This study examined associations between adult attachment dimensions, perceived health status and worrying (coping strategy with chronic pain), and explored whether worrying mediated observed relationships between attachment dimensions and health outcomes within a sample of 128 Portuguese female fibromyalgia patients. Physical health status was inversely correlated with dependence and worrying; mental health status was positively correlated with trust, and inversely related to attachment-related ambivalence, dependence and worrying. Finally, worrying mediated relationships between dependence and both physical and mental health status; moreover, worrying partially mediated the relationship between ambivalence and mental health status. Implications of the findings are discussed.

    DeFalco, Amelia

    2016-09-01

    This essay considers the ways in which graphic caregiving memoirs complicate the idealizing tendencies of ethics of care philosophy. The medium's "capacious" layering of words, images, temporalities, and perspectives produces "productive tensions. . . The words and images entwine, but never synthesize" (Chute 2010, 5). In graphic memoirs about care, this "capaciousness" allows for quick oscillation between the rewards and struggles of care work, representing ambiguous, even ambivalent attitudes toward care. Graphic memoirs effectively represent multiple perspectives without synthesis, part of a structural and thematic ambivalence that provides a provocative counterpart to the abstract idealism of ethics of care philosophy.

    Full Text Available In this paper the psychometric data of a scale of evaluation of the social abilities (social expression and motor skills are presented. The scale was constructed to investigate social competence and antisocial conduct in adolescence. The process of the scale’s construction is explained; and the data on its internal consistency, its test-retest reliability, and its concurrent validity are presented. The scale was filled out by 325 teachers from different schools in the city of Badajoz (Spain; however, 20 scales were rejected because they were not properly completed. As well, the scale was analyzed, giving as a result 9 factors that explain 59.4% of the total variance. With the results obtained, the position of situational specificity with regard to social abilities is supported.

    Full Text Available Abstract Background This paper compiles data from different sources to get a first comprehensive picture of psychometric and other methodological characteristics of the Menopause Rating Scale (MRS scale. The scale was designed and standardized as a self-administered scale to (a to assess symptoms/complaints of aging women under different conditions, (b to evaluate the severity of symptoms over time, and (c to measure changes pre- and postmenopause replacement therapy. The scale became widespread used (available in 10 languages. Method A large multinational survey (9 countries in 4 continents from 2001/ 2002 is the basis for in depth analyses on reliability and validity of the MRS. Additional small convenience samples were used to get first impressions about test-retest reliability. The data were centrally analyzed. Data from a postmarketing HRT study were used to estimate discriminative validity. Results Reliability measures (consistency and test-retest stability were found to be good across countries, although the sample size for test-retest reliability was small. Validity: The internal structure of the MRS across countries was astonishingly similar to conclude that the scale really measures the same phenomenon in symptomatic women. The sub-scores and total score correlations were high (0.7–0.9 but lower among the sub-scales (0.5–0.7. This however suggests that the subscales are not fully independent. Norm values from different populations were presented showing that a direct comparison between Europe and North America is possible, but caution recommended with comparisons of data from Latin America and Indonesia. But this will not affect intra-individual comparisons within clinical trials. The comparison with the Kupperman Index showed sufficiently good correlations, illustrating an adept criterion-oriented validity. The same is true for the comparison with the generic quality-of-life scale SF-36 where also a sufficiently close association

    Scale invariance is the case where the solution of a physical process at a specified time-space scale can be linearly related to the solution of the processes at another time-space scale. Recent studies investigated the scale invariance conditions of hydrodynamic processes by applying the one-parameter Lie scaling transformations to the governing equations of the processes. Scale invariance of a physical process is usually achieved under certain conditions on the scaling ratios of the variables and parameters involved in the process. The foundational axioms of hydrodynamics are the conservation laws, namely, conservation of mass, conservation of linear momentum, and conservation of energy from continuum mechanics. They are formulated using the Reynolds transport theorem. Conventionally, Reynolds transport theorem formulates the conservation equations in integral form. Yet, differential form of the conservation equations can also be derived for an infinitesimal control volume. In the formulation of the governing equation of a process, one or more than one of the conservation laws and, some times, a constitutive relation are combined together. Differential forms of the conservation equations are used in the governing partial differential equation of the processes. Therefore, differential conservation equations constitute the fundamentals of the governing equations of the hydrodynamic processes. Applying the one-parameter Lie scaling transformation to the conservation laws in the Reynolds transport theorem framework instead of applying to the governing partial differential equations may lead to more fundamental conclusions on the scaling and scale invariance of the hydrodynamic processes. This study will investigate the scaling behavior and scale invariance conditions of the hydrodynamic processes by applying the one-parameter Lie scaling transformation to the conservation laws in the Reynolds transport theorem framework.

  15. From Punched Cards to "Big Data": A Social History of Database Populism

    2012-08-01

    Full Text Available Since the diffusion of the punched card tabulator following the 1890 U.S. Census, mass-scale information processing has been alternately a site of opportunity, ambivalence and fear in the American imagination. While large bureaucracies have tended to deploy database technology toward purposes of surveillance and control, the rise of personal computing made databases accessible to individuals and small businesses for the first time. Today, the massive collection of trace communication data by public and private institutions has renewed popular anxiety about the role of the database in society. This essay traces the social history of database technology across three periods that represent significant changes in the accessibility and infrastructure of information processing systems. Although many proposed uses of "big data" seem to threaten individual privacy, a largely-forgotten database populism from the 1970s and 1980s suggests that a reclamation of small-scale data processing might lead to sharper popular critique in the future.

  16. Salzburger State Reactance Scale (SSR Scale): Validation of a Scale Measuring State Reactance.

    Sittenthaler, Sandra; Traut-Mattausch, Eva; Steindl, Christina; Jonas, Eva

    This paper describes the construction and empirical evaluation of an instrument for measuring state reactance, the Salzburger State Reactance (SSR) Scale. The results of a confirmatory factor analysis supported a hypothesized three-factor structure: experience of reactance, aggressive behavioral intentions, and negative attitudes. Correlations with divergent and convergent measures support the validity of this structure. The SSR Subscales were strongly related to the other state reactance measures. Moreover, the SSR Subscales showed modest positive correlations with trait measures of reactance. The SSR Subscales correlated only slightly or not at all with neighboring constructs (e.g., autonomy, experience of control). The only exception was fairness scales, which showed moderate correlations with the SSR Subscales. Furthermore, a retest analysis confirmed the temporal stability of the scale. Suggestions for further validation of this questionnaire are discussed.

  18. Phenomenology of local scale invariance: from conformal invariance to dynamical scaling

    2002-01-01

    Statistical systems displaying a strongly anisotropic or dynamical scaling behaviour are characterized by an anisotropy exponent θ or a dynamical exponent z. For a given value of θ (or z), we construct local scale transformations, which can be viewed as scale transformations with a space-time-dependent dilatation factor. Two distinct types of local scale transformations are found. The first type may describe strongly anisotropic scaling of static systems with a given value of θ, whereas the second type may describe dynamical scaling with a dynamical exponent z. Local scale transformations act as a dynamical symmetry group of certain non-local free-field theories. Known special cases of local scale invariance are conformal invariance for θ=1 and Schroedinger invariance for θ=2. The hypothesis of local scale invariance implies that two-point functions of quasi primary operators satisfy certain linear fractional differential equations, which are constructed from commuting fractional derivatives. The explicit solution of these yields exact expressions for two-point correlators at equilibrium and for two-point response functions out of equilibrium. A particularly simple and general form is found for the two-time auto response function. These predictions are explicitly confirmed at the uniaxial Lifshitz points in the ANNNI and ANNNS models and in the aging behaviour of simple ferromagnets such as the kinetic Glauber-Ising model and the kinetic spherical model with a non-conserved order parameter undergoing either phase-ordering kinetics or non-equilibrium critical dynamics

    Energy consuming appliances accounted for over 40% of the energy use and $17 billion in sales in the U.S. in 2014. Whether such amounts of money and energy were optimally combined to produce household energy services is not straightforwardly determined. The efficient allocation of capital and energy to provide an energy service has been previously approached, and solved with Data Envelopment Analysis (DEA) under constant returns to scale. That approach, however, lacks the scale dimension of the problem and may restrict the economic efficient models of an appliance available in the market when constant returns to scale does not hold. We expand on that approach to estimate returns to scale for energy using appliances. We further calculate DEA scale efficiency scores for the technically efficient models that comprise the economic efficient frontier of the energy service delivered, under different assumptions of returns to scale. We then apply this approach to evaluate dishwashers available in the market in the U.S. Our results show that (a) for the case of dishwashers scale matters, and (b) the dishwashing energy service is delivered under non-decreasing returns to scale. The results further demonstrate that this method contributes to increase consumers’ choice of appliances.

    2012-01-01

    Full Text Available Abstract Background Hierarchical scales are very useful in clinical practice due to their ability to discriminate precisely between individuals, and the original English version of the Myocardial Infarction Dimensional Assessment Scale has been shown to contain a hierarchy of items. The purpose of this study was to analyse a Mandarin Chinese translation of the Myocardial Infarction Dimensional Assessment Scale for a hierarchy of items according to the criteria of Mokken scaling. Data from 180 Chinese participants who completed the Chinese translation of the Myocardial Infarction Dimensional Assessment Scale were analysed using the Mokken Scaling Procedure and the 'R' statistical programme using the diagnostics available in these programmes. Correlation between Mandarin Chinese items and a Chinese translation of the Short Form (36 Health Survey was also analysed. Findings Fifteen items from the Mandarin Chinese Myocardial Infarction Dimensional Assessment Scale were retained in a strong and reliable Mokken scale; invariant item ordering was not evident and the Mokken scaled items of the Chinese Myocardial Infarction Dimensional Assessment Scale correlated with the Short Form (36 Health Survey. Conclusions Items from the Mandarin Chinese Myocardial Infarction Dimensional Assessment Scale form a Mokken scale and this offers further insight into how the items of the Myocardial Infarction Dimensional Assessment Scale relate to the measurement of health-related quality of life people with a myocardial infarction.

    Numerical model representations of decadal- to centennial-scale soil-carbon dynamics are a dominant cause of uncertainty in climate change predictions. Recent attempts by some Earth System Model (ESM) teams to integrate previously unrepresented soil processes (e.g., explicit microbial processes, abiotic interactions with mineral surfaces, vertical transport), poor performance of many ESM land models against large-scale and experimental manipulation observations, and complexities associated with spatial heterogeneity highlight the nascent nature of our community's ability to accurately predict future soil carbon dynamics. I will present recent work from our group to develop a modeling framework to integrate pore-, column-, watershed-, and global-scale soil process representations into an ESM (ACME), and apply the International Land Model Benchmarking (ILAMB) package for evaluation. At the column scale and across a wide range of sites, observed depth-resolved carbon stocks and their 14C derived turnover times can be explained by a model with explicit representation of two microbial populations, a simple representation of mineralogy, and vertical transport. Integrating soil and plant dynamics requires a 'process-scaling' approach, since all aspects of the multi-nutrient system cannot be explicitly resolved at ESM scales. I will show that one approach, the Equilibrium Chemistry Approximation, improves predictions of forest nitrogen and phosphorus experimental manipulations and leads to very different global soil carbon predictions. Translating model representations from the site- to ESM-scale requires a spatial scaling approach that either explicitly resolves the relevant processes, or more practically, accounts for fine-resolution dynamics at coarser scales. To that end, I will present recent watershed-scale modeling work that applies reduced order model methods to accurately scale fine-resolution soil carbon dynamics to coarse-resolution simulations. Finally, we

    Zipf's law and Heaps' law are two representatives of the scaling concepts, which play a significant role in the study of complexity science. The coexistence of the Zipf's law and the Heaps' law motivates different understandings on the dependence between these two scalings, which has still hardly been clarified. In this article, we observe an evolution process of the scalings: the Zipf's law and the Heaps' law are naturally shaped to coexist at the initial time, while the crossover comes with the emergence of their inconsistency at the larger time before reaching a stable state, where the Heaps' law still exists with the disappearance of strict Zipf's law. Such findings are illustrated with a scenario of large-scale spatial epidemic spreading, and the empirical results of pandemic disease support a universal analysis of the relation between the two laws regardless of the biological details of disease. Employing the United States domestic air transportation and demographic data to construct a metapopulation model for simulating the pandemic spread at the U.S. country level, we uncover that the broad heterogeneity of the infrastructure plays a key role in the evolution of scaling emergence. The analyses of large-scale spatial epidemic spreading help understand the temporal evolution of scalings, indicating the coexistence of the Zipf's law and the Heaps' law depends on the collective dynamics of epidemic processes, and the heterogeneity of epidemic spread indicates the significance of performing targeted containment strategies at the early time of a pandemic disease.

    Staff in the emergency departments of hospitals are reported as being negative or ambivalent toward suicidal or self-harming individuals. According to the literature, these patients are subjected to stigmatization and lack of empathy. This phenomenon has been linked to a decreased quality of care offered to these individuals and to missing an important opportunity to prevent further suicidal behavior or repetition of deliberate self-harm. Also, protocols, proper guidelines and education for the emergency staff call for a revision and an implementation. In this paper, evidence suggesting staff attitudes toward suicidal and self-harming patients is reviewed. An overview of related issues such as clinical judgment, the use of scales and nurses' role is also included in this report.

    2013-05-01

    We present techniques to process large scale-free graphs in distributed memory. Our aim is to scale to trillions of edges, and our research is targeted at leadership class supercomputers and clusters with local non-volatile memory, e.g., NAND Flash. We apply an edge list partitioning technique, designed to accommodate high-degree vertices (hubs) that create scaling challenges when processing scale-free graphs. In addition to partitioning hubs, we use ghost vertices to represent the hubs to reduce communication hotspots. We present a scaling study with three important graph algorithms: Breadth-First Search (BFS), K-Core decomposition, and Triangle Counting. We also demonstrate scalability on BG/P Intrepid by comparing to best known Graph500 results. We show results on two clusters with local NVRAM storage that are capable of traversing trillion-edge scale-free graphs. By leveraging node-local NAND Flash, our approach can process thirty-two times larger datasets with only a 39% performance degradation in Traversed Edges Per Second (TEPS). © 2013 IEEE.

    The Social Interaction Anxiety Scale and Social Phobia Scale are companion measures for assessing symptoms of social anxiety and social phobia. The scales have good reliability and validity across several samples, however, exploratory and confirmatory factor analyses have yielded solutions comprising substantially different item content and factor structures. These discrepancies are likely the result of analyzing items from each scale separately or simultaneously. The current investigation sets out to assess items from those scales, both simultaneously and separately, using exploratory and confirmatory factor analyses in an effort to resolve the factor structure. Participants consisted of a clinical sample (n 5353; 54% women) and an undergraduate sample (n 5317; 75% women) who completed the Social Interaction Anxiety Scale and Social Phobia Scale, along with additional fear-related measures to assess convergent and discriminant validity. A three-factor solution with a reduced set of items was found to be most stable, irrespective of whether the items from each scale are assessed together or separately. Items from the Social Interaction Anxiety Scale represented one factor, whereas items from the Social Phobia Scale represented two other factors. Initial support for scale and factor validity, along with implications and recommendations for future research, is provided. (c) 2009 Wiley-Liss, Inc.

  7. JY1 time scale: a new Kalman-filter time scale designed at NIST

    2017-01-01

    We report on a new Kalman-filter hydrogen-maser time scale (i.e. JY1 time scale) designed at the National Institute of Standards and Technology (NIST). The JY1 time scale is composed of a few hydrogen masers and a commercial Cs clock. The Cs clock is used as a reference clock to ease operations with existing data. Unlike other time scales, the JY1 time scale uses three basic time-scale equations, instead of only one equation. Also, this time scale can detect a clock error (i.e. time error, frequency error, or frequency drift error) automatically. These features make the JY1 time scale stiff and less likely to be affected by an abnormal clock. Tests show that the JY1 time scale deviates from the UTC by less than  ±5 ns for ∼100 d, when the time scale is initially aligned to the UTC and then is completely free running. Once the time scale is steered to a Cs fountain, it can maintain the time with little error even if the Cs fountain stops working for tens of days. This can be helpful when we do not have a continuously operated fountain or when the continuously operated fountain accidentally stops, or when optical clocks run occasionally. (paper)

    Full Text Available Abstract Background There is a high prevalence of depression in patients with heart failure (HF that is associated with worsening prognosis. The value of using a reliable and valid instrument to measure depression in this population is therefore essential. We validated the Cardiac Depression Scale (CDS in heart failure patients using a model of ordinal unidimensional measurement known as Mokken scaling. Findings We administered in face-to-face interviews the CDS to 603 patients with HF. Data were analysed using Mokken scale analysis. Items of the CDS formed a statistically significant unidimensional Mokken scale of low strength (H0.8. Conclusions The CDS has a hierarchy of items which can be interpreted in terms of the increasingly serious effects of depression occurring as a result of HF. Identifying an appropriate instrument to measure depression in patients with HF allows for early identification and better medical management.

    Various studies have reported a positive relationship between child maltreatment and personality disorders (PDs). However, few studies included all DSM-IV PDs and even fewer adjusted for other forms of childhood adversity, e.g. bullying or family problems. We analyzed questionnaires completed by 512 participants of the ZInEP epidemiology survey, a comprehensive psychiatric survey of the general population in Zurich, Switzerland. Associations between childhood adversity and PDs were analyzed bivariately via simple regression analyses and multivariately via multiple path analysis. The bivariate analyses revealed that all PD dimensions were significantly related to various forms of family and school problems as well as child abuse. In contrast, according to the multivariate analysis only school problems and emotional abuse were associated with various PDs. Poverty was uniquely associated with schizotypal PD, conflicts with parents with obsessive-compulsive PD, physical abuse with antisocial PD, and physical neglect with narcissistic PD. Sexual abuse was statistically significantly associated with schizotypal and borderline PD, but corresponding effect sizes were small. Childhood adversity has a serious impact on PDs. Bullying and violence in schools and emotional abuse appear to be more salient markers of general personality pathology than other forms of childhood adversity. Associations with sexual abuse were negligible when adjusted for other forms of adversity. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Full Text Available The present study was aimed to investigate the prevalence of personality disorders and its relationship with personality traits among students. This research was among epidemiological-correlational descriptive studies. Method: For this purpose, 389 male students were selected via a multi-stage cluster sampling method. All subjects completed Millon's personality disorder (1987 and five-factor personality Costaand McCrae's questionnaires (1989. Results: The results showed that the prevalence of personality disorders is among students. It was also found that there existed a positive correlation between schizoid, avoidant, dependent, schizotypal, borderline and paranoid personality disorders with Neuroticism factor (r = .1. There was a significant negative correlation between schizoid, avoidant and schizotypal personality disorders with extraversion factor (r = .1 and significant positive correlation between histrionic disorders and extraversion (r = .1. There was a significant negative correlation between dependent personality disorder and Openness factor (r = .1 , significant negative correlation between narcissistic, antisocial and paranoid personality disorders with agree ableness factor (r = .1 and finally, significant negative correlation between antisocial, passive-aggressive and borderline personality disorders with accountability factor (r = .1and a significant positive correlation between accountability factor and compulsive personality disorder (r = .1. Conclusion: The results suggest a prevalence of personality disorders among students and significant correlation between some disorders with personality factors. Further studies in this area could provide more insightful findings in the field.

    Structural studies of orogenic deformation fields are mostly based on small-scale structures ubiquitous in field exposures, hand samples, and under microscopes. Relating deformation histories derived from such structures to changing lithospheric-scale deformation and boundary conditions is not trivial due to vast scale separation (10-6 107 m) between characteristic lengths of small-scale structures and lithospheric plates. Rheological heterogeneity over the range of orogenic scales will lead to deformation partitioning throughout intervening scales of structural development. Spectacular examples of structures documenting deformation partitioning are widespread within hot (i.e., magma-rich) orogens such as the well-studied central Sierra Nevada and Cascades core of western North America: (1) deformation partitioned into localized, narrow, triclinic shear zones separated by broad domains of distributed pure shear at micro- to 10 km scales; (2) deformation partitioned between plutons and surrounding metamorphic host rocks as shown by pluton-wide magmatic fabrics consistently oriented differently than coeval host rock fabrics; (3) partitioning recorded by different fabric intensities, styles, and orientations established from meter-scale grid mapping to 100 km scale domainal analyses; and (4) variations in the causes of strain and kinematics within fold-dominated domains. These complex, partitioned histories require synthesized mapping, geochronology, and structural data at all scales to evaluate partitioning and in the absence of correct scaling can lead to incorrect interpretations of histories. Forward modeling capable of addressing deformation partitioning in materials containing multiple scales of rheologically heterogeneous elements of varying characteristic lengths provides the ability to upscale the large synthesized datasets described above to plate-scale tectonic processes and boundary conditions. By comparing modeling predictions from the recently developed

    While a large body of descriptive work has thoroughly investigated the clinical correlates of atypical depression, little is known about its fundamental origins. This study examined atypical depression from an attachment theory framework. Our hypothesis was that, compared to adults with melancholic depression, those with atypical depression would report more anxious-ambivalent attachment and less secure attachment. As gender has been an important consideration in prior work on atypical depression, this same hypothesis was further tested in female subjects only. One hundred ninety-nine consecutive adults presenting to a tertiary mood disorders clinic with major depressive disorder with either atypical or melancholic features according to the Structured Clinical Interview for DSM-IV Axis-I Disorders were administered a self-report adult attachment questionnaire to assess the core dimensions of secure, anxious-ambivalent, and avoidant attachment. Attachment scores were compared across the 2 depressed groups defined by atypical and melancholic features using multivariate analysis of variance. The study was conducted between 1999 and 2004. When men and women were considered together, the multivariate test comparing attachment scores by depressive group was statistically significant at p depression was associated with significantly lower secure attachment scores, with a trend toward higher anxious-ambivalent attachment scores, than was melancholia. When women were analyzed separately, the multivariate test was statistically significant at p depressive groups. These preliminary findings suggest that attachment theory, and insecure and anxious-ambivalent attachment in particular, may be a useful framework from which to study the origins, clinical correlates, and treatment of atypical depression. Gender may be an important consideration when considering atypical depression from an attachment perspective. Copyright 2009 Physicians Postgraduate Press, Inc.

    Distress screening programs aim to ensure appropriate psycho-oncological support for cancer patients, but many eligible patients do not use these services. To improve distress management, we need to better understand patients' supportive care needs. In this paper, we report the first key finding from a longitudinal study that focused on patients' intentions to use psycho-oncological support, and its association with distress and uptake of the psycho-oncology service. We conducted a prospective, observational study in an Oncology Outpatient Clinic and assessed distress, intention to use psycho-oncological support, and uptake of the psycho-oncology service using the Distress Thermometer (DT), a semi-structured interview, and hospital records. We analyzed data with a mixed-methods approach. Of 333 patients (mean age 61 years; 55% male; 54% DT≥5), 25% intended to use the psycho-oncology service (yes), 33% were ambivalent (maybe), and 42% reported no intention (no). Overall, 23% had attended the psycho-oncology service four months later. Ambivalent patients reported higher distress than patients with no intention (odds ratio (OR)=1.18, 95% confidence interval (CI)[1.06-1.32]) but showed significantly lower uptake behavior than patients with an intention (OR=14.04, 95%CI [6.74-29.24]). Qualitative analyses revealed that ambivalent patients (maybe) emphasized fears and uncertainties, while patients with clear intentions (yes/no) emphasized knowledge, attitudes, and coping concepts. We identified a vulnerable group of ambivalent patients with high distress levels and low uptake behavior. To optimize distress screening programs, we suggest addressing and discussing patients' supportive care needs in routine clinical practice. This article is protected by copyright.

    from physical considerations we would expect the scales to interact in a qualitatively similar way within the flow and across different turbulent flows. Therefore, instead of the large-scale fluctuations, the large-scale gradients modulation of the small scales has been additionally investigated.

    © 2016 Cambridge University Press. The interaction between the large and the small scales of turbulence is investigated in a mixing layer, at a Reynolds number based on the Taylor microscale of , via direct numerical simulations. The analysis is performed in physical space, and the local vorticity root-mean-square (r.m.s.) is taken as a measure of the small-scale activity. It is found that positive large-scale velocity fluctuations correspond to large vorticity r.m.s. on the low-speed side of the mixing layer, whereas, they correspond to low vorticity r.m.s. on the high-speed side. The relationship between large and small scales thus depends on position if the vorticity r.m.s. is correlated with the large-scale velocity fluctuations. On the contrary, the correlation coefficient is nearly constant throughout the mixing layer and close to unity if the vorticity r.m.s. is correlated with the large-scale velocity gradients. Therefore, the small-scale activity appears closely related to large-scale gradients, while the correlation between the small-scale activity and the large-scale velocity fluctuations is shown to reflect a property of the large scales. Furthermore, the vorticity from unfiltered (small scales) and from low pass filtered (large scales) velocity fields tend to be aligned when examined within vortical tubes. These results provide evidence for the so-called \\'scale invariance\\' (Meneveau & Katz, Annu. Rev. Fluid Mech., vol. 32, 2000, pp. 1-32), and suggest that some of the large-scale characteristics are not lost at the small scales, at least at the Reynolds number achieved in the present simulation.

  16. Small-scale microwave background anisotropies implied by large-scale data

    1993-01-01

    In the absence of reheating microwave background radiation (MBR) anisotropies on arcminute scales depend uniquely on the amplitude and the coherence length of the primordial density fluctuations (PDFs). These can be determined from the recent data on galaxy correlations, xi(r), on linear scales (APM survey). We develop here expressions for the MBR angular correlation function, C(theta), on arcminute scales in terms of the power spectrum of PDFs and demonstrate their accuracy by comparing with detailed calculations of MBR anisotropies. We then show how to evaluate C(theta) directly in terms of the observed xi(r) and show that the APM data give information on the amplitude, C(O), and the coherence angle of MBR anisotropies on small scales.

    A novel integrated simulation of radiative transfer in metal foams is presented. It integrates the continuous-scale simulation with the direct discrete-scale simulation in a single computational domain. It relies on the coupling of the real discrete-scale foam geometry with the equivalent continuous-scale medium through a specially defined scale-coupled zone. This zone holds continuous but nonhomogeneous volumetric radiative properties. The scale-coupled approach is compared to the traditional continuous-scale approach using volumetric radiative properties in the equivalent participating medium and to the direct discrete-scale approach employing the real 3D foam geometry obtained by computed tomography. All the analyses are based on geometrical optics. The Monte Carlo ray-tracing procedure is used for computations of the absorbed radiative fluxes and the apparent radiative behaviors of metal foams. The results obtained by the three approaches are in tenable agreement. The scale-coupled approach is fully validated in calculating the apparent radiative behaviors of metal foams composed of very absorbing to very reflective struts and that composed of very rough to very smooth struts. This new approach leads to a reduction in computational time by approximately one order of magnitude compared to the direct discrete-scale approach. Meanwhile, it can offer information on the local geometry-dependent feature and at the same time the equivalent feature in an integrated simulation. This new approach is promising to combine the advantages of the continuous-scale approach (rapid calculations) and direct discrete-scale approach (accurate prediction of local radiative quantities).

    The objective of conducting experiments in a laboratory is to gain data that helps in designing and operating large-scale biological processes. However, the scale-up and design of industrial-scale biohydrogen production reactors is still uncertain. In this paper, an established and proven Eulerian-Eulerian computational fluid dynamics (CFD) model was employed to perform hydrodynamics assessments of an industrial-scale continuous stirred-tank reactor (CSTR) for biohydrogen production. The merits of the laboratory-scale CSTR and industrial-scale CSTR were compared and analyzed on the basis of CFD simulation. The outcomes demonstrated that there are many parameters that need to be optimized in the industrial-scale reactor, such as the velocity field and stagnation zone. According to the results of hydrodynamics evaluation, the structure of industrial-scale CSTR was optimized and the results are positive in terms of advancing the industrialization of biohydrogen production.

    Full Text Available Reducing emission from deforestation and forest degradation and associated benefits (REDD+, has received much attention as one of the most controversial climate change initiatives, especially by forest fringed community actors in sub-Saharan Africa (SSA and Southeast Asia, (SEA who are skeptical of the scheme.The object of this paper is to examine the seeming potential benefits and accompanying risks and challenges of REDD+ on the livelihoods among smallholder farmers in SSA and SEA. The paper espouses the sustainability context of REDD+ projects as pro-poor forest management mechanisms; through the provision of alternative livelihood. This is achieved through critical review and critique of scientific articles, project reports and relevant documents on REDD+ interventions from a worldwide, regional to local scale. The paper identifies projects that seem to solidify claims that REDD+ projects are simply a new form of colonialism; which the West is using to take advantage of vulnerable groups in the South. The paper concludes with the need to actively engage sub-Saharan African and Southeast Asian women in climate change mitigation benefit schemes on account of the expedient role women play in agricultural activities (which may involve deforestation and forest land degradation.

    2011-02-01

    The purpose of this study was to examine the hierarchical and cumulative nature of the 35 items of the Myocardial Infarction Dimensional Assessment Scale (MIDAS), a disease-specific health-related quality of life measure. Data from 668 participants who completed the MIDAS were analysed using the Mokken Scaling Procedure, which is a computer program that searches polychotomous data for hierarchical and cumulative scales on the basis of a range of diagnostic criteria. Fourteen MIDAS items were retained in a Mokken scale and these items included physical activity, insecurity, emotional reaction and dependency items but excluded items related to diet, medication or side-effects. Item difficulty, in item response theory terms, ran from physical activity items (low difficulty) to insecurity, suggesting that the most severe quality of life effect of myocardial infarction is loneliness and isolation. Items from the MIDAS form a strong and reliable Mokken scale, which provides new insight into the relationship between items in the MIDAS and the measurement of quality of life after myocardial infarction. © 2010 Blackwell Publishing Ltd.

    Group-based clinical supervision is commonly offered as a stress-reducing intervention in psychiatric settings, but nurses often feel ambivalent about participating. This study aimed at exploring psychiatric nurses' experiences of participating in groupbased supervision and identifying psychosocial...... reasons for their ambivalence. Semi-structured interviews were conducted with 22 psychiatric nurses at a Danish university hospital. The results indicated that participation in clinical supervision was difficult for the nurses because of an uncomfortable exposure to the professional community. The sense...... of exposure was caused by the particular interactional organisation during the sessions, which brought to light pre-existing but covert conflicts among the nurses....

    Full Text Available Ma (2009 is a single channel video of a mother and child walking together side by side, holding hands. The title is reminiscent of the affectionate nickname for a mother, 'Ma', but also a concealed way to convey maternal ambivalence. Maternal ambivalence is the result of the tension between the idealisation of motherhood and women’s lived experience of mothering. The maternal struggle finds its source in the difficulty of identifying with the ideological representation of the mother. This image still conveys an idealistic and nostalgic, patriarchal image of maternal love bounded by culture and history. http://podcast.ulcc.ac.uk/accounts/BirkbeckCollege/mamsie/MA.mov

    Motivational interviewing (MI) is a potentially useful tool for clinicians who are exploring ways to improve treatment outcomes with depressed clients. MI techniques may be particularly appropriate with depressed adolescents, for whom motivation to engage in therapy is often a problem and who often experience ambivalence about life choices. The present article presents a case description of MI with a depressed adolescent who was ambivalent about what life change to pursue. MI was used to help the client identify conflicts between her values, learn how they were contributing to her distress, and move toward resolving them. Advantages and limitations of these techniques are discussed.

  7. Parallel Computing in SCALE

    2010-01-01

    The SCALE computational architecture has remained basically the same since its inception 30 years ago, although constituent modules and capabilities have changed significantly. This SCALE concept was intended to provide a framework whereby independent codes can be linked to provide a more comprehensive capability than possible with the individual programs - allowing flexibility to address a wide variety of applications. However, the current system was designed originally for mainframe computers with a single CPU and with significantly less memory than today's personal computers. It has been recognized that the present SCALE computation system could be restructured to take advantage of modern hardware and software capabilities, while retaining many of the modular features of the present system. Preliminary work is being done to define specifications and capabilities for a more advanced computational architecture. This paper describes the state of current SCALE development activities and plans for future development. With the release of SCALE 6.1 in 2010, a new phase of evolutionary development will be available to SCALE users within the TRITON and NEWT modules. The SCALE (Standardized Computer Analyses for Licensing Evaluation) code system developed by Oak Ridge National Laboratory (ORNL) provides a comprehensive and integrated package of codes and nuclear data for a wide range of applications in criticality safety, reactor physics, shielding, isotopic depletion and decay, and sensitivity/uncertainty (S/U) analysis. Over the last three years, since the release of version 5.1 in 2006, several important new codes have been introduced within SCALE, and significant advances applied to existing codes. Many of these new features became available with the release of SCALE 6.0 in early 2009. However, beginning with SCALE 6.1, a first generation of parallel computing is being introduced. In addition to near-term improvements, a plan for longer term SCALE enhancement

    The influence on social behavior of beliefs in Satan and the nature of evil has received little empirical study. Elaine Pagels (1995) in her book, The Origin of Satan, argued that Christians' intolerance toward others is due to their belief in an active Satan. In this study, more than 200 college undergraduates completed the Manitoba Prejudice Scale and the Attitudes Toward Homosexuals Scale (B. Altemeyer, 1988), as well as the Belief in an Active Satan Scale, developed by the authors. The Belief in an Active Satan Scale demonstrated good internal consistency and temporal stability. Correlational analyses revealed that for the female participants, belief in an active Satan was directly related to intolerance toward lesbians and gay men and intolerance toward ethnic minorities. For the male participants, belief in an active Satan was directly related to intolerance toward lesbians and gay men but was not significantly related to intolerance toward ethnic minorities. Results of this research showed that it is possible to meaningfully measure belief in an active Satan and that such beliefs may encourage intolerance toward others.

  9. Small scale models equal large scale savings

    1994-01-01

    A physical scale model of a reactor is a tool which can be used to reduce the time spent by workers in the containment during an outage and thus to reduce the radiation dose and save money. The model can be used for worker orientation, and for planning maintenance, modifications, manpower deployment and outage activities. Examples of the use of models are presented. These were for the La Salle 2 and Dresden 1 and 2 BWRs. In each case cost-effectiveness and exposure reduction due to the use of a scale model is demonstrated. (UK)

  16. Ambivalent Sexism and Religion: Connected Through Values.

    Science.gov (United States)

    Mikołajczak, Małgorzata; Pietrzak, Janina

    2014-01-01

    Sexist attitudes do not exist in a limbo; they are embedded in larger belief systems associated with specific hierarchies of values. In particular, manifestations of benevolent sexism (Glick and Fiske 1996, 1997, 2001) can be perceived as a social boon, not a social ill, both because they are experienced as positive, and because they reward behaviors that maintain social stability. One of the strongest social institutions that create and justify specific hierarchies of values is religion. In this paper, we examine how the values inherent in religious beliefs (perhaps inadvertently) propagate an unequal status quo between men and women through endorsement of ideologies linked to benevolent sexism. In a survey with a convenience sample of train passengers in Southern and Eastern Poland ( N  = 180), we investigated the relationship between Catholic religiosity and sexist attitudes. In line with previous findings (Gaunt 2012; Glick et al. 2002a; Taşdemir and Sakallı-Uğurlu 2010), results suggest that religiosity can be linked to endorsement of benevolent sexism. This relationship was mediated in our study by the values of conservatism and openness to change (Schwartz 1992): religious individuals appear to value the societal status quo, tradition, and conformity, which leads them to perceive women through the lens of traditional social roles. Adhering to the teachings of a religion that promotes family values in general seems to have as its byproduct an espousal of prejudicial attitudes toward specific members of the family.

Pour interroger la dynamique du temps choisi impulsée par les 35 heures, deux dimensions du temps de travail sont examinées : son contenant, à savoir les aspects externes, morphologiques ou géométriques tels que la durée et l’horaire de travail ; et son contenu, à savoir les aspects internes ou constitutifs se rapportant à la mise en œuvre de la force de travail.

The study was carried out in a local branch of the French public healthcare system and reveals that workers are ambivalent about selected time : though they gain some power in deciding how long they will work and how to manage their schedule, they have lost control over their actual working time, i.e. over the organization and content of their professional activity.

    In the recent years, first decade-long kilometer-scale resolution RCM simulations have been performed on continental-scale computational domains. However, the size of the planet Earth is still an order of magnitude larger and thus the computational implications of performing global climate simulations at this resolution are challenging. We explore the gap between the currently established RCM simulations and global simulations by scaling the GPU accelerated version of the COSMO model to a near-global computational domain. To this end, the evolution of an idealized moist baroclinic wave has been simulated over the course of 10 days with a grid spacing of up to 930 m. The computational mesh employs 36'000 x 16'001 x 60 grid points and covers 98.4% of the planet's surface. The code shows perfect weak scaling up to 4'888 Nodes of the Piz Daint supercomputer and yields 0.043 simulated years per day (SYPD) which is approximately one seventh of the 0.2-0.3 SYPD required to conduct AMIP-type simulations. However, at half the resolution (1.9 km) we've observed 0.23 SYPD. Besides formation of frontal precipitating systems containing embedded explicitly-resolved convective motions, the simulations reveal a secondary instability that leads to cut-off warm-core cyclonic vortices in the cyclone's core, once the grid spacing is refined to the kilometer scale. The explicit representation of embedded moist convection and the representation of the previously unresolved instabilities exhibit a physically different behavior in comparison to coarser-resolution simulations. The study demonstrates that global climate simulations using kilometer-scale resolution are imminent and serves as a baseline benchmark for global climate model applications and future exascale supercomputing systems.

    2016-01-01

    The book serves both as a reference for various scaled models with corresponding dimensionless numbers, and as a resource for learning the art of scaling. A special feature of the book is the emphasis on how to create software for scaled models, based on existing software for unscaled models. Scaling (or non-dimensionalization) is a mathematical technique that greatly simplifies the setting of input parameters in numerical simulations. Moreover, scaling enhances the understanding of how different physical processes interact in a differential equation model. Compared to the existing literature, where the topic of scaling is frequently encountered, but very often in only a brief and shallow setting, the present book gives much more thorough explanations of how to reason about finding the right scales. This process is highly problem dependent, and therefore the book features a lot of worked examples, from very simple ODEs to systems of PDEs, especially from fluid mechanics.

    1978-01-01

    Two full-scale heating experiments and a time-scale heating experiment have recently been started in granite 340 meters below surface. The purpose of the full-scale heating experiments is to assess the near-field effects of thermal loading for the design of an underground repository of nuclear wastes. That of the time-scale heating experiments is to obtain field data of the interaction between heaters and its effect on the rock mass during a period of about two years, which corresponds to about twenty years of full-scale operation. Geological features of the rock around each experiment have been mapped carefully, and temperatures, stresses and displacements induced in the rock by heating have been calculated in advance of the experiments. Some 800 different measurements are recorded at frequent intervals by a computer system situated underground. These data can be compared at any time with predictions made earlier on video display units underground

    A basic principle within the addictions treatment field is that social support is a vital ingredient in the recovery process. This study examines the nature of social support in a sample of opioid-dependent men and women who are currently being treated in a medication-assisted treatment program (methadone). This research examines the types of social support behaviors that the opioid-dependent individuals consider helpful and explores whether attachment style (i.e., secure, ambivalent, or anxious attachment) was a determining factor in whether social support was perceived as helpful. The dependent variables included readiness to change addictive behaviors and abstinence from other mood-altering drugs. Participants (N = 159) completed a demographic questionnaire, the Significant Others Scale, the Experiences in Close Relationships Scale, the Multidimensional Scale of Perceived Social Support Assessment, the Readiness to Change Scale, and an Attachment Style Questionnaire. The demographic questionnaire included subjective ratings of self-improvement. Social support predicted perceived improvement in all of the areas examined (e.g., health, family/social relationships) and abstinence; however, attachment style did not predict improvement or with readiness to change. Social support is an important factor in one's recovery from substance use disorders. Yet attachment style (i.e., anxious, avoidant, or secure) did not predict abstinence or overall improvement in functioning.

    This work analyzes how the assumption of responsibility by aggressors convicted for gender-based violence is related to sexist attitudes, self-esteem and perceived functional social support. Similarly, the predictive capacity of these variables is studied with respect to the aggressors' minimization of the harm done and a lack of attributing responsibility to themselves. The participants in the research were males condemned to prison sentences for crimes related with gender-based violence in Spain. The instruments applied were the Attribution of Responsibility and Minimization of Harm Scale, the Ambivalent Sexism Inventory (ASI), the Rosenberg Self-Esteem Scale (RSE), the Functional Social Support Questionnaire (FSSQ), and the Social Desirability Scale (SDS). The study concludes that sexist attitudes are related with a greater lack of attribution of responsibility, as well as with a greater tendency to minimize the harm done by the aggression. In addition, the aggressors with low self-esteem use self-defense as a strategy to justify the violence. Similarly, the presence of an adequate social support network for the aggressor increases the attribution of responsibility on the part of those convicted for gender-based violence.

    801The Savannah River Laboratory has requested that the Idaho National Engineering Laboratory perform an analysis to help define, examine, and assess potential concepts for the design of a scaled integral hydraulics test facility representative of the current Savannah River Plant reactor design. In this report the thermal-hydraulic phenomena of importance (based on the knowledge and experience of the authors and the results of the joint INEL/TPG/SRL phenomena identification and ranking effort) to reactor safety during the design basis loss-of-coolant accident were examined and identified. Established scaling methodologies were used to develop potential concepts for integral hydraulic testing facilities. Analysis is conducted to examine the scaling of various phenomena in each of the selected concepts. Results generally support that a one-fourth (1/4) linear scale visual facility capable of operating at pressures up to 350 kPa (51 psia) and temperatures up to 330 K (134 degree F) will scale most hydraulic phenomena reasonably well. However, additional research will be necessary to determine the most appropriate method of simulating several of the reactor components, since the scaling methodology allows for several approaches which may only be assessed via appropriate research. 34 refs., 20 figs., 14 tabs

    We consider the minimal supersymmetric Standard Model with large scalar and gaugino mass terms at the GUT scale, which are generated predominantly by gauge-mediated supersymmetry breaking. For certain ratios of GUT-scale masses, determined by the messenger indices, large radiative corrections lead to a small electroweak scale in a way which resembles the well-known focus point mechanism. The Fermi scale, the gravitino mass and the higgsino masses are of comparable size. For a Higgs mass of about 124 GeV all other superparticles have masses outside the reach of the LHC. (orig.)

  9. Commensurate scale relations: Precise tests of quantum chromodynamics without scale or scheme ambiguity

    We derive commensurate scale relations which relate perturbatively calculable QCD observables to each other, including the annihilation ratio R e+ e - , the heavy quark potential, τ decay, and radiative corrections to structure function sum rules. For each such observable one can define an effective charge, such as α R (√s)/π ≡ R e+ e - (√s)/(3Σe q 2 )-1. The commensurate scale relation connecting the effective charges for observables A and B has the form α A (Q A ) α B (Q B )(1 + r A/Bπ / αB + hor-ellipsis), where the coefficient r A/B is independent of the number of flavors ∫ contributing to coupling renormalization, as in BLM scale-fixing. The ratio of scales Q A /Q B is unique at leading order and guarantees that the observables A and B pass through new quark thresholds at the same physical scale. In higher orders a different renormalization scale Q n* is assigned for each order n in the perturbative series such that the coefficients of the series are identical to that of a invariant theory. The commensurate scale relations and scales satisfy the renormalization group transitivity rule which ensures that predictions in PQCD are independent of the choice of an intermediate renormalization scheme C. In particular, scale-fixed predictions can be made without reference to theoretically constructed singular renormalization schemes such as MS. QCD can thus be tested in a new and precise way by checking that the effective charges of observables track both in their relative normalization and in their commensurate scale dependence. The commensurate scale relations which relate the radiative corrections to the annihilation ratio R e + e - to the radiative corrections for the Bjorken and Gross-Llewellyn Smith sum rules are particularly elegant and interesting

    Background : Research has shown that suicide is a phenomenon highly present among the drug dependent population. Different studies have demonstrated an upraised level of comorbidity between personality disorders (PD) and substance use disorders (SUD). This study aimed to describe which PDs are more frequent among those patients with a risk of suicide. Methods : The study was based on a consecutive non-probabilistic convenience sample of 196 bereaved patients attended to in a Public Addiction Center in Girona (Spain). Sociodemographic data, as well as suicide and drug related characteristics were recorded. The risk of suicide was assessed with the Spanish version of "Risk of suicide". Personality disorders were measured with the Spanish version of Millon Multiaxial Clinical Inventory. Results : The PDs more associated with the presence of risk of suicide were depressive, avoidant, schizotypal and borderline disorders. However, the histrionic, narcissistic and compulsive PDs are inversely associated with risk of suicide even though the narcissistic scale had no statistical correlation. Conclusions : The risk of suicide is a significant factor to take into account related to patients with SUD and especially with the presence of specific PDs. These findings underline the importance of diagnosing and treating rigorously patients with SUD.

    Scaling in the context of REACH means: use of simple mathematics to check, whether chemi-cals are used in a safe way. Even in case if certain conditions of use deviate from the exposure scenario. In specific cases, scaling offers downstream users the opportunity to demonstrate coverage by an exposure scenario for their individual conditions of use. In this report we describe the duty of downstream users to check their conditions of use. We give a definition of scaling related to REACH. We describe objectives and results of scaling. We characterise available scaling tools in a structured way. We describe options for further development and harmonisation of scaling tools. Under use of the experience with existing tools, we develop a guidance document on scaling. Three examples in this guidance make clear how scaling works. In five steps. The guidance is addressed to persons using substances in industrial or professional applications - downstream users according to REACH. In addition, the guidance supports producers of substances and formulators who want to develop scaling tools for their customers. The report includes a calculation table for scaling related to the environment (REACH Scale Environment). In addition, it includes a template to generate product-specific scaling tools. This report focuses on scaling related to environmental exposure assessment. Scaling is possible related to workers and consumer exposure, too. References for this are given in chapter 7. (orig.)

  12. Interpreting the Third International Mathematics and Science Study (TIMSS) achievement scales using scale anchoring

    Kelly, Dana L.

    1999-11-01

    The scale anchoring method was used to analyze and describe the TIMSS primary and middle school (Populations 1 and 2) mathematics and science achievement scales. Scale anchoring is a way of attaching meaning to a scale by describing what students know and can do at specific points on the scale. Student achievement was scrutinized at four points on the TIMSS primary and middle school achievement scales---the 25th, 50th, 75th, and 90th international percentiles for fourth and eighth grades. The scale anchoring method was adapted for the TIMSS data and items that students scoring at each of the four scale points were likely to answer correctly (with a 65 percent probability) were identified. The items were assembled in binders organized by anchor level and content area. Two ten-member panels of subject-matter specialists were convened to scrutinize the items, draft descriptions of student proficiency at the four scale points, and identify example TIMSS items to illustrate performance at each level. Following the panel meetings, the descriptions were refined through an iterative review process. The result is a content-referenced interpretation of the TIMSS scales through which TIMSS achievement results can be better communicated and understood.

  13. Beyond KNO scaling

    Hegyi, S.

    1998-01-01

    A generalization of the Koba-Nielsen-Olesen scaling law of the multiplicity distributions P(n) is presented. It consists of a change in the normalization point of P(n) compensated by a suitable change in the renormalized parameters and a rescaling. The iterative repetition of the transformation yields the sequence of higher-order moment distributions of P(n). Each member of this sequence may exhibit data collapsing behavior in case of violation of the original KNO scaling hypothesis. It is shown that the iterative procedure can be viewed as varying the collision energy, i.e. the moment distributions of P(n) can represent the pattern of pre-asymptotic KNO scaling violation. The fixed points of the iteration will be determined and a consistency test based on Feynman scaling is to be given. (author)

  14. Dynamic critical behaviour and scaling

    International Nuclear Information System (INIS)

    Oezoguz, B.E.

    2001-01-01

    Traditionally the scaling is the property of dynamical systems at thermal equilibrium. In second order phase transitions scaling behaviour is due to the infinite correlation length around the critical point. In first order phase transitions however, the correlation length remains finite and a different type of scaling can be observed. For first order phase transitions all singularities are governed by the volume of the system. Recently, a different type of scaling, namely dynamic scaling has attracted attention in second order phase transitions. In dynamic scaling, when a system prepared at high temperature is quenched to the critical temperature, it exhibits scaling behaviour. Dynamic scaling has been applied to various spin systems and the validity of the arguments are shown. Firstly, in this thesis project the dynamic scaling is applied to 4-dimensional using spin system which exhibits second order phase transition with mean-field critical indices. Secondly, it is shown that although the dynamic is quite different, first order phase transitions also has a different type of dynamic scaling

  15. Ripple scalings in geothermal facilities, a key to understand the scaling process

    Köhl, Bernhard; Grundy, James; Baumann, Thomas

    2017-04-01

    Scalings are a widespread problem among geothermal plants which exploit the Malm Aquifer in the Bavarian Molasse Zone. They effect the technical and economic efficiency of geothermal plants. The majority of the scalings observed at geothermal facilities exploring the Malm aquifer in the Bavarian Molasse Basin are carbonates. They are formed due to a disruption of the lime-carbonic-acid equilibrium during production caused by degassing of CO2. These scalings are found in the production pipes, at the pumps and at filters and can nicely be described using existing hydrogeochemical models. This study proposes a second mechanism for the formation of scalings in ground-level facilities. We investigated scalings which accumulated at the inlet to the heat exchanger. Interestingly, the scalings were recovered after the ground level facilities had been cleaned. The scalings showed distinct ripple structures, which is likely a result of solid particle deposition. From the ripple features the the flow conditions during their formation were calculated based on empirical equations (Soulsby, 2012). The calculations suggest that the deposits were formed during maintenance works. Thin section images of the sediments indicate a two-step process: deposition of sediment grains, followed by stabilization with a calcite layer. The latter likely occured during maintenance. To prevent this type of scalings blocking the heat exchangers, the maintenance procedure has to be revised. References: Soulsby, R. L.; Whitehouse, R. J. S.; Marten, K.

    2011-06-01

    Our aim was to develop a clinimetric scale evaluating motor phenomena, associated features, and severity of psychogenic nonepileptic seizures (PNES). Sixty video/EEG-recorded PNES induced by suggestion maneuvers were evaluated. We examined the relationship between results from this scale and results from the Clinical Global Impression (CGI) scale to validate this technique. Interrater reliabilities of the PNES scale for three raters were analyzed using the AC1 statistic, Kendall's coefficient of concordance (KCC), and intraclass correlation coefficients (ICCs). The relationship between the CGI and PNES scales was evaluated with Spearman correlations. The AC1 statistic demonstrated good interrater reliability for each phenomenon analyzed (tremor/oscillation, tonic; clonic/jerking, hypermotor/agitation, atonic/akinetic, automatisms, associated features). KCC and the ICC showed moderate interrater agreement for phenomenology, associated phenomena, and total PNES scores. Spearman's correlation of mean CGI score with mean total PNES score was 0.69 (Pscale described here accurately evaluates the phenomenology of PNES and could be used to assess and compare subgroups of patients with PNES.

    Yuan, M

    1997-12-31

    Water-scaling is a common and major production chemistry problem in the North Sea oil and gas fields and scale prediction has been an important means to assess the potential and extent of scale deposition. This paper presents an overview of sulphate and carbonate scaling problems in the North Sea and a review of several widely used and commercially available scale prediction software. In the paper, the water chemistries and scale types and severities are discussed relative of the geographical distribution of the fields in the North Sea. The theories behind scale prediction are then briefly described. Five scale or geochemical models are presented and various definitions of saturation index are compared and correlated. Views are the expressed on how to predict scale precipitation under some extreme conditions such as that encountered in HPHT reservoirs. 15 refs., 7 figs., 9 tabs.

  19. Effect of wettability on scale-up of multiphase flow from core-scale to reservoir fine-grid-scale

    Energy Technology Data Exchange (ETDEWEB)

    Chang, Y.C.; Mani, V.; Mohanty, K.K. [Univ. of Houston, TX (United States)

    1997-08-01

    Typical field simulation grid-blocks are internally heterogeneous. The objective of this work is to study how the wettability of the rock affects its scale-up of multiphase flow properties from core-scale to fine-grid reservoir simulation scale ({approximately} 10{prime} x 10{prime} x 5{prime}). Reservoir models need another level of upscaling to coarse-grid simulation scale, which is not addressed here. Heterogeneity is modeled here as a correlated random field parameterized in terms of its variance and two-point variogram. Variogram models of both finite (spherical) and infinite (fractal) correlation length are included as special cases. Local core-scale porosity, permeability, capillary pressure function, relative permeability functions, and initial water saturation are assumed to be correlated. Water injection is simulated and effective flow properties and flow equations are calculated. For strongly water-wet media, capillarity has a stabilizing/homogenizing effect on multiphase flow. For small variance in permeability, and for small correlation length, effective relative permeability can be described by capillary equilibrium models. At higher variance and moderate correlation length, the average flow can be described by a dynamic relative permeability. As the oil wettability increases, the capillary stabilizing effect decreases and the deviation from this average flow increases. For fractal fields with large variance in permeability, effective relative permeability is not adequate in describing the flow.

    Policy studies often evaluate health for an individual or for a population by using measurement scales that are ordinal scales or expected-utility scales. This paper develops scales of a different type, commonly called cardinal scales, that measure changes in health. Also, we argue that cardinal...... scales provide a meaningful and useful means of evaluating health policies. Thus, we develop a means of using the perspective of early neoclassical welfare economics as an alternative to ordinalist and expected-utility perspectives....

    The authors propose and provide support for a new absolute flux scale for radio astronomy, which is not encumbered with the inadequacies of the previous scales. In constructing it the method of relative spectra was used (a powerful tool for choosing reference spectra). A review is given of previous flux scales. The authors compare the AIS scale with the scale they propose. Both scales are based on absolute measurements by the ''artificial moon'' method, and they are practically coincident in the range from 0.96 to 6 GHz. At frequencies above 6 GHz, 0.96 GHz, the AIS scale is overestimated because of incorrect extrapolation of the spectra of the primary and secondary standards. The major results which have emerged from this review of absolute scales in radio astronomy are summarized

    2002-10-01

    This is the third article in a series of 10-year reviews of rating scales. Here, the authors review scales that are useful in tapping the affective disturbances experienced with various psychiatric disorders, including suicidality, cognitive style, and self-esteem. The authors sampled articles incorporating these constructs over the past 25 years and selected scales with established uses or new development. Those presented here have adequate psychometric properties and high utility for efficiently elucidating youths' functioning, plus either wide literature citations or a special niche. These scales were developed bimodally. Many were developed in the 1980s when internalizing disorders were elucidated, but there has been a resurgence of interest in these constructs. Scales assessing suicidality have clear constructs, whereas scales of cognitive style demonstrate deficits in developmental relevance, and scales of self-esteem suffer from lax constructs. The constructs underlying these scales tap core symptoms of internalizing disorders, mediate the expression of affective disturbances associated with various disorders, and depict the impairments resulting from these disorders. Overall, the psychometrics of these scales are adequate. These scales provide a broader representation of youths' functioning than that conveyed with diagnostic scales alone.

  4. HEALTH-RISK BEHAVIOUR IN REGARD OF FAMILY STRUCTURE AND ITS EFFECT ON ACADEMIC ACHIEVEMENT

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available The frequency of health-risk behaviours like smoking, alcohol consumption and substance use is usually higher in adolescence. In addition, its appearance is higher among students coming from non-intact families. These factors also have a strong influence on academic achievement as students from fragile families and students having these health-damaging habits tend to be less effective. According to our results, four different student clusters can be detected regarding health behaviour (traditional risk-takers, hard risk-takers, ambivalent students and risk-avoiders. Ambivalent students reached the best achievement while hard risk-takers showed the poorest efficacy. Finally, students from intact families showed better results compared to their peers from single-parent or patchwork families.

    The Social Interaction Anxiety Scale (SIAS) and the Social Phobia Scale (SPS) are two compendium measures that have become some of the most popular self-report scales of social anxiety. Despite their popularity, it remains unclear whether it is necessary to maintain two separate scales of social anxiety. The primary objective of the present study was to examine the factor analytic structure of both measures to determine the factorial validity of each scale. For this purpose, we administered both scales to 577 patients at the beginning of outpatient treatment. Analyzing both scales simultaneously, a CFA with two correlated factors showed a better fit to the data than a single factor model. An additional EFA with an oblique rotation on all 40 items using the WLSMV estimator further supported the two factor solution. These results suggest that the SIAS and SPS measure similar, but not identical facets of social anxiety. Thus, our findings provide support to retain the SIAS and SPS as two separate scales.

    2016-01-01

    A scaling study of several thousand Nb$_{3}$Sn critical-current $(I_c)$ measurements is used to derive the Extrapolative Scaling Expression (ESE), a relation that can quickly and accurately extrapolate limited datasets to obtain full three-dimensional dependences of I c on magnetic field (B), temperature (T), and mechanical strain (ε). The relation has the advantage of being easy to implement, and offers significant savings in sample characterization time and a useful tool for magnet design. Thorough data-based analysis of the general parameterization of the Unified Scaling Law (USL) shows the existence of three universal scaling constants for practical Nb$_{3}$Sn conductors. The study also identifies the scaling parameters that are conductor specific and need to be fitted to each conductor. This investigation includes two new, rare, and very large I c(B,T,ε) datasets (each with nearly a thousand I c measurements spanning magnetic fields from 1 to 16 T, temperatures from ~2.26 to 14 K, and intrinsic strain...

    2007-01-01

    Effective environmental management of DOE sites requires reliable prediction of reactive transport phenomena. A central issue in prediction of subsurface reactive transport is the impact of multiscale physical, chemical, and biological heterogeneity. Heterogeneity manifests itself through incomplete mixing of reactants at scales below those at which concentrations are explicitly defined (i.e., the numerical grid scale). This results in a mismatch between simulated reaction processes (formulated in terms of average concentrations) and actual processes (controlled by local concentrations). At the field scale, this results in apparent scale-dependence of model parameters and inability to utilize laboratory parameters in field models. Accordingly, most field modeling efforts are restricted to empirical estimation of model parameters by fitting to field observations, which renders extrapolation of model predictions beyond fitted conditions unreliable. The objective of this project is to develop a theoretical and computational framework for (1) connecting models of coupled reactive transport from pore-scale processes to field-scale bioremediation through a hierarchy of models that maintain crucial information from the smaller scales at the larger scales; and (2) quantifying the uncertainty that is introduced by both the upscaling process and uncertainty in physical parameters. One of the challenges of addressing scale-dependent effects of coupled processes in heterogeneous porous media is the problem-specificity of solutions. Much effort has been aimed at developing generalized scaling laws or theories, but these require restrictive assumptions that render them ineffective in many real problems. We propose instead an approach that applies physical and numerical experiments at small scales (specifically the pore scale) to a selected model system in order to identify the scaling approach appropriate to that type of problem. Although the results of such studies will

    2018-01-01

    This paper addresses the formation of infant attachment types within the context of active inference: a holistic account of action, perception and learning in the brain. We show how the organised forms of attachment (secure, avoidant and ambivalent) might arise in (Bayesian) infants. Specifically, we show that these distinct forms of attachment emerge from a minimisation of free energy—over interoceptive states relating to internal stress levels—when seeking proximity to caregivers who have a varying impact on these interoceptive states. In line with empirical findings in disrupted patterns of affective communication, we then demonstrate how exteroceptive cues (in the form of caregiver-mediated AMBIANCE affective communication errors, ACE) can result in disorganised forms of attachment in infants of caregivers who consistently increase stress when the infant seeks proximity, but can have an organising (towards ambivalence) effect in infants of inconsistent caregivers. In particular, we differentiate disorganised attachment from avoidance in terms of the high epistemic value of proximity seeking behaviours (resulting from the caregiver’s misleading exteroceptive cues) that preclude the emergence of coherent and organised behavioural policies. Our work, the first to formulate infant attachment in terms of active inference, makes a new testable prediction with regards to the types of affective communication errors that engender ambivalent attachment.

    Most theories of psychotic-like experiences posit the involvement of social-cognitive mechanisms. The current research examined the relations between psychotic-like experiences and two social-cognitive mechanisms, high aberrant salience and low self-concept clarity. In particular, we examined whether aberrant salience, or the incorrect assignment of importance to neutral stimuli, and low self-concept clarity interacted to predict psychotic-like experiences. The current research included three large samples (n = 667, 724, 744) of participants and over-sampled for increased schizotypal personality traits. In all three studies, an interaction between aberrant salience and self-concept clarity was found such that participants with high aberrant salience and low self-concept clarity had the highest levels of psychotic-like experiences. In addition, aberrant salience and self-concept clarity interacted to predict a supplemental measure of delusions in Study 2. In Study 3, in contrast to low self-concept clarity, neuroticism did not interact with aberrant salience to predict psychotic-like experiences, suggesting that the relation between low self-concept clarity and psychosis may not be due to neuroticism. Additionally, aberrant salience and self-concept clarity did not interact to predict to other schizotypal personality disorder criteria, social anhedonia or trait paranoia, which suggests the interaction is specific to psychotic-like experiences. Overall, our results are consistent with several social-cognitive models of psychosis suggesting that aberrant salience and self-concept clarity might be important mechanisms in the occurrence of psychotic-like symptoms.

    2002-01-01

    We propose a framework in which the quantum gravity scale can be as low as 10 -3 eV. The key assumption is that the standard model ultraviolet cutoff is much higher than the quantum gravity scale. This ensures that we observe conventional weak gravity. We construct an explicit brane-world model in which the brane-localized standard model is coupled to strong 5D gravity of infinite-volume flat extra space. Because of the high ultraviolet scale, the standard model fields generate a large graviton kinetic term on the brane. This kinetic term 'shields' the standard model from the strong bulk gravity. As a result, an observer on the brane sees weak 4D gravity up to astronomically large distances beyond which gravity becomes five dimensional. Modeling quantum gravity above its scale by the closed string spectrum we show that the shielding phenomenon protects the standard model from an apparent phenomenological catastrophe due to the exponentially large number of light string states. The collider experiments, astrophysics, cosmology and gravity measurements independently point to the same lower bound on the quantum gravity scale, 10 -3 eV. For this value the model has experimental signatures both for colliders and for submillimeter gravity measurements. Black holes reveal certain interesting properties in this framework

    2017-04-01

    Human mobility is known to be distributed across several orders of magnitude of physical distances, which makes it generally difficult to endogenously find or define typical and meaningful scales. Relevant analyses, from movements to geographical partitions, seem to be relative to some ad-hoc scale, or no scale at all. Relying on geotagged data collected from photo-sharing social media, we apply community detection to movement networks constrained by increasing percentiles of the distance distribution. Using a simple parameter-free discontinuity detection algorithm, we discover clear phase transitions in the community partition space. The detection of these phases constitutes the first objective method of characterising endogenous, natural scales of human movement. Our study covers nine regions, ranging from cities to countries of various sizes and a transnational area. For all regions, the number of natural scales is remarkably low (2 or 3). Further, our results hint at scale-related behaviours rather than scale-related users. The partitions of the natural scales allow us to draw discrete multi-scale geographical boundaries, potentially capable of providing key insights in fields such as epidemiology or cultural contagion where the introduction of spatial boundaries is pivotal.

  18. Scales and erosion

    Science.gov (United States)

    There is a need to develop scale explicit understanding of erosion to overcome existing conceptual and methodological flaws in our modelling methods currently applied to understand the process of erosion, transport and deposition at the catchment scale. These models need to be based on a sound under...

  19. Understanding scaling laws

    Accelerator scaling laws how they can be generated, and how they are used are discussed. A scaling law is a relation between machine parameters and beam parameters. An alternative point of view is that a scaling law is an imposed relation between the equations of motion and the initial conditions. The relation between the parameters is obtained by requiring the beam to be matched. (A beam is said to be matched if the phase-space distribution function is a function of single-particle invariants of the motion.) Because of this restriction, the number of independent parameters describing the system is reduced. Using simple models for bunched- and unbunched-beam situations. Scaling laws are shown to determine the general behavior of beams in accelerators. Such knowledge is useful in design studies for new machines such as high-brightness linacs. The simple model presented shows much of the same behavior as a more detailed RFQ model

    The SCALE Code System is a widely-used modeling and simulation suite for nuclear safety analysis and design that is developed, maintained, tested, and managed by the Reactor and Nuclear Systems Division (RNSD) of Oak Ridge National Laboratory (ORNL). SCALE provides a comprehensive, verified and validated, user-friendly tool set for criticality safety, reactor and lattice physics, radiation shielding, spent fuel and radioactive source term characterization, and sensitivity and uncertainty analysis. Since 1980, regulators, licensees, and research institutions around the world have used SCALE for safety analysis and design. SCALE provides an integrated framework with dozens of computational modules including three deterministic and three Monte Carlo radiation transport solvers that are selected based on the desired solution strategy. SCALE includes current nuclear data libraries and problem-dependent processing tools for continuous-energy (CE) and multigroup (MG) neutronics and coupled neutron-gamma calculations, as well as activation, depletion, and decay calculations. SCALE includes unique capabilities for automated variance reduction for shielding calculations, as well as sensitivity and uncertainty analysis. SCALE’s graphical user interfaces assist with accurate system modeling, visualization of nuclear data, and convenient access to desired results.SCALE 6.2 provides many new capabilities and significant improvements of existing features.New capabilities include:• ENDF/B-VII.1 nuclear data libraries CE and MG with enhanced group structures,• Neutron covariance data based on ENDF/B-VII.1 and supplemented with ORNL data,• Covariance data for fission product yields and decay constants,• Stochastic uncertainty and correlation quantification for any SCALE sequence with Sampler,• Parallel calculations with KENO,• Problem-dependent temperature corrections for CE calculations,• CE shielding and criticality accident alarm system analysis with MAVRIC,• CE
