    To report the psychometric properties of the Psychological-Behavioral Acculturation Scale (P-BAS), a tool gauging behavioral and psychological acculturation after adapting it through formative research to people of Mexican origin in the United States. We analyzed data from adapted P-BAS questionnaires in the TalaSurvey study, using standard methods to establish internal consistencies (Cronbach's alpha), construct validity, and ascertain if the value orientation profile differed by ethnic group. In 2012-13, 505 respondents (mean age 45.2 ± 14.1, 56% female) participated: 250 European Americans (EA) and 255 people of Mexican origin (MA). Although internal consistencies of 15 value orientation measures were occasionally low, overall results were encouraging. A weighted combination of value orientation scores strongly discriminated between EA and MA. Additionally, the pattern of relationships among MAs identified between acculturation scores and the validity contrasts supported the construct validity of the proposed dual framework. The trend was particularly evident for most behavioral variables.

    Transient ischaemic attack (TIA) is often associated with anxiety and depression, which may precipitate secondary stroke and interfere with treatment. The Hospital Anxiety and Depression Scale (HADS) is widely used to assess these states and to inform the management of any associated psychological problems, but there is considerable debate about what it actually measures. The HADS scores from a range of different clinical groups have been reviewed in order to assess its psychometric properties, but so far, no research has examined either its latent structure when used with TIA patients, or the association between symptom severity and the test's validity. The aims of this study, therefore, were to investigate: (a) the underlying structure of the HADS when used with TIA patients; and (b) the impact of symptom severity on the validity of the HADS. The HADS and a functional capacity measure were administered by post to a sample of 542 confirmed TIA patients. Exploratory factor analysis was conducted on the HADS scores to establish its underlying structure for this clinical group, and then, sub-sample correlations were undertaken between the anxiety/depression scores for different levels of functional capacity. Two factors emerged, with 13 of the 14 HADS items loading significantly on both, suggesting there is a common affective state underlying the standard anxiety and depression scales. Further data-exploration indicated that convergence between these affective states increased as functional capacity deteriorated. The results suggest firstly that the HADS measures general subjective distress when used with TIA patients, and secondly that the higher reported symptom severity in this clinical group may be associated with reduced affective differentiation. As the ability to retain clear affective discrimination is associated with health and well-being, this could provide a focus for post-TIA rehabilitation.

    Full Text Available The article presents the results of the development and approbation of the scale of psychological essentialism (belief in invariability of group membership. The results of confirmatory factor analysis conducted on eight different groups (ethnic (Russians / Tajiks / Jews, gender groups (men / women, homosexuals (gay / lesbians and religious groups (Orthodox / Muslim (n = 897, demonstrated the good fit to empirical data. The multi-group confirmatory factor analysis revealed that the different groups measured on the scale, can be compared with each other within a single category. The scale shows good convergent and discriminant validity. On the one hand, psychological essentialism associated with group entitativity, group identification, right-wing authoritarianism, social dominance orientation and justification the social hierarchy; on the other hand there are not correlation between the psychological essentialism and open to experience and attitude to novelty.

  6. Scalar Implicatures: The psychological reality of scales

    Full Text Available Scalar implicatures, the phenomena where a sentence like The pianist played some Mozart sonatas is interpreted as The pianist did not play all Mozart sonatas have been given two different analyses. Neo-Griceans claim that this interpretation is based on lexical scales (e.g. , where the stronger term (e.g. all implies the weaker term (e.g. some, but the weaker term (e.g., some implicates the negation of the stronger term (i.e., some = not all. Post-Griceans deny that this is the case and offer a context-based inferential account for scalar implicatures. While scalar implicatures have been extensively investigated, with results apparently in favor of post-Gricean accounts, the psychological reality of lexical scales has not been put to the test. This is what we have done in the present experiment, with a lexical decision task using lexical scales in a masked priming paradigm. While Post-Gricean accounts do not attribute any role for lexical scales in the computation of scalar implicatures, Neo-Gricean accounts suggest that lexical scales are the core mechanism behind the computation of scalar implicatures, and predict that weaker terms in a scale should prime stronger terms more than the reverse because stronger words are necessary to the interpretation of weaker words, while stronger words can be interpreted independently of weaker words. Our results provided evidence in favor of the psychological existence of scales, leading to the first clear experimental support for the Neo-Gricean account.

    The purpose of this study was to construct Jung's Psychological Types Scale (JPTS), and to examine its reliability and validity. First, 87 pairs of items were written, and their content validity examined by two Jungian analysts, who judged 74 pairs of them to be appropriate. In Study 1 542 undergraduates, 245 men and 297 women, responded to the interim scale. Exploratory factor analysis found three factors: extraversion-introversion (E-I), thinking-feeling (T-F), and sensation-intuition (S-N). Results of additional factor analyses indicated that the three factors were almost orthogonal. Then, nine item pairs each for the subscales were selected for the JPTS. The scale had high alpha and test-retest reliability coefficients. In Study 2, concurrent validity of the scale was examined in terms of Myers-Briggs Type Indicator (MBTI) Form M. The correlations showed meaningful patterns for concurrent validity. In addition, the scale was evaluated in terms of NEO Five Factor Inventory (NEO-FFI), a five-factor model (FFM) scale. The result showed that the three factors of E-I, T-F, and S-N corresponded to Extraversion (positive), Agreeableness (negative), and Openness (negative) of NEO-FFI, respectively.

    Understanding organisation at different social scales is crucial to learning how social processes play a role in sustainable natural resource management. Research has neglected the potential role that individual personality plays in decision making in natural resource management. In the past two decades natural resource management across rural Australia has increasingly come under the direct influence of voluntary participatory groups, such as Catchment Management Authorities. The greater complexity of relationships among all stakeholders is a serious management challenge when attempting to align their differing aspirations and values at four social institutional scales-local, regional, state and national. This is an exploratory study on the psychological composition of groups of stakeholders at the four social scales in natural resource management in Australia. This article uses the theory of temperaments and the Myers-Briggs Type Indicator (MBTI) to investigate the distribution of personality types. The distribution of personality types in decision-making roles in natural resource management was markedly different from the Australian Archive sample. Trends in personality were found across social scales with Stabilizer temperament more common at the local scale and Theorist temperament more common at the national scale. Greater similarity was found at the state and national scales. Two temperaments comprised between 76 and 90% of participants at the local and regional scales, the common temperament type was Stabilizer. The dissimilarity was Improviser (40%) at the local scale and Theorist (29%) at the regional scale. Implications for increasing participation and bridging the gap between community and government are discussed.

    In the present paper the role of the state of the psychological contract to predict psychological health results is studied in a sample of 385 employees of different Spanish companies. Results indicate that the state of the psychological contract significantly predicts life satisfaction, work-family conflict and well-being beyond the prediction produced by the content of the psychological contract. In addition, trust and fairness, two dimensions of the state of psychological contract, all together contribute to explain these psychological health variables adding value to the role as predictor of fulfillment of the psychological contract. The results support the approach argued by Guest and colleagues.

    Psychological work maturity is an important concept in situational leadership theory. The present research revised the Psychological Work Maturity Scale for use in Chinese organizations. Three samples of full-time employees (Ns = 205, 266, and 283) from different companies and industries participated in the present study. Confirmatory factor analysis showed that a single-factor structure fit the data. The scale had acceptable reliabilities, convergent and criterion-related validities, and was shown to be an appropriate measure of psychological work maturity in Chinese employees. Maturity differences in several demographic variables were not found, but employees with longer tenure in Sample 2 scored higher on maturity, which shows that psychological work maturity may be dependent on personal development in the interaction with the varying situational factors, especially in the work domain. Implications for research and practice on psychological work maturity in China are discussed.

    This uncontrolled intervention study explored the effects of sauna bathing utilizing residual heat from charcoal kilns (charcoal kiln saunas) on psychological states. Forty-five volunteers (24 males and 21 females; mean age 51.9 years (S.D. 15.7) visiting a bamboo charcoal kiln in Japan participated in the study. They completed a shortened version of the Profile of Mood States (POMS) and State-Trait Anxiety Inventory (STAI) before and after charcoal kiln sauna bathing in order to determine mood and anxiety states. Six factors relating to mood were measured using the POMS: Tension-Anxiety, Depression-Dejection, Anger-Hostility, Vigor, Fatigue, and Confusion. The two anxiety concepts of state anxiety and trait anxiety were also measured. Changes in psychological states before and after sauna bathing were then determined. All mood scales and both manifest anxiety measures were improved after sauna bathing. Charcoal kiln sauna bathing appears to improve mood and decrease anxiety. It is a limitation of this study that this was a descriptive prospective and an uncontrolled intervention study. Further investigation of the improvement of trait anxiety is required.

    Psychological ownership is rarely considered in health discourse related to chronic illness or disease state. Construction of identity is an important consideration within this framework. This autoethnographic study explores psychological ownership and identity related to prostate cancer and chronic illness. Conclusions about the nature of psychological ownership and identity were gathered from the relevant literature and personal experience. Themes include the patient-healthcare professional relationship and that psychological ownership is personal and grounded in an individual's sense of identity, control and perceived capacity to control illness or disease. Personal reflection through autoethnography guides discussion of psychological ownership and identity. © 2010 Blackwell Publishing Ltd.

    The MMPI-2 and WAIS-IV are commonly used together in neuropsychological evaluations yet little is known about their interrelationships. This study explored the potential influence of psychological factors on WAIS-IV performance in a sample of 180 predominantly male veteran referrals that underwent a comprehensive neuropsychological examination in a VA Medical Center. Exclusionary criteria included failed performance validity testing and self-report distortion on the MMPI-2. A Principal Components Analysis was performed on the 15 MMPI-2 content scales, yielding three broader higher-order psychological dimensions: Internalized Emotional Dysfunction (IED), Externalized Emotional Dysfunction (EED), and Fear. Level of IED was not related to performance on the WAIS-IV Full Scale IQ or its four indexes: (Verbal Comprehension, Perceptual Reasoning, Working Memory, and Processing Speed). EED was not related to WAIS-IV performance. Level of Fear, which encompasses health preoccupations (HEA) and distorted perceptions (BIZ), was significantly related to WAIS-IV Full Scale IQ and Verbal Comprehension. These results challenge the common use of high scores on the MMPI-2 IED measures (chiefly depression and anxiety) to explain deficient WAIS-IV performance. In addition, they provide impetus for further investigation of the relation between verbal intelligence and Fear.

    Chronic neck pain is one of the most usual neuromusculoskeletal pain conditions which can lead patients to chronic disability. Similarly to other pain conditions, the changed psychological status of these patients is believed to be associated with their pain condition and disability. However, the association between the psychological status of patients with idiopathic neck pain and their pain intensity and disability is minimally explored. This study was aimed at investigating the association between psychological states (anxiety, depression, kinesiophobia, catastrophizing) of patients with chronic idiopathic neck pain and self-reported pain and disability. Forty five patients with idiopathic chronic neck pain (more than 6 months, at least once a week) participated. Their psychological states were assessed by using the Hospital Anxiety and Depression scale, Pain Catastrophizing scale and Tampa Scale for Kinesiophobia. Self-reported disability was recorded with the Neck Disability Index. Pain intensity was recorded by using a visual analog scale. Neck pain intensity was significantly correlated with anxiety (p< 0.05). Disability was significantly correlated with anxiety, depression and catastrophizing (p< 0.05). Multiple regression analysis showed that pain-induced disability can be significantly predicted by anxiety and catastrophizing (p< 0.05). It can be concluded that anxiety, depression and catastrophizing of patients with chronic neck pain is associated with their self-reported disability, whereas anxiety is also associated with their pain intensity. Anxiety and catastrophizing may be important predicting markers of patients' self-reported disability.

    2017-05-01

    Psychological vulnerability is related to cognitive beliefs that reflect dependence on one's sense of self-worth and to maladaptive functioning. It is a disadvantage that renders people less protected to face negative life experiences. The purpose of this study was to adapt and test the psychometric properties of the Psychological Vulnerability Scale in a sample of 267 Portuguese higher education students. A psychometric study of the Psychological Vulnerability Scale, after translation into Portuguese, was performed with a convenience sample of higher education students. Participants were asked to fill in the sociodemographic questionnaire, the Psychological Vulnerability Scale, the Brief Symptom Inventory, and a one-item question about the Perception of Vulnerability. The mean age of the participants was 20.5 years ( SD = 3.3). A factor analysis confirmed the original one-factor structure, explaining 42.9% of the total variance. The Psychological Vulnerability Scale showed adequate internal consistency and excellent test-retest stability. Convergent validity was confirmed by positive correlations with the Brief Symptom Inventory and Perception of Vulnerability. Overall, the Psychological Vulnerability Scale showed good validity, reliability, and stability over time. The Psychological Vulnerability Scale is now ready to be used by practitioners and researchers to measure the psychological vulnerability among Portuguese higher education students. These data add to the body of knowledge of psychiatric and mental health nursing and provides support for the use of the Psychological Vulnerability Scale in higher education students.

    Patients with advanced illness often have high rates of psychological symptoms. Many multicomponent palliative care intervention studies have investigated the efficacy of overall symptom reduction; however, little research has focused explicitly on how interventions address psychological symptoms associated with serious illness. The current study reviewed 59 multicomponent palliative care intervention articles and analyzed the mental health components of palliative care interventions and their outcomes in order to better understand the current state of psychological care in palliative care. The majority of articles (69.5%) did not provide any details regarding the psychological component delivered as part of the palliative care intervention. Most (54.2%) studies did not specify which provider on the team was responsible for providing the psychological intervention. Studies varied regarding the type of outcome measure utilized; multi-symptom assessment scales were used in 54.2% of studies, mental health scales were employed in 25.4%, quality of life and distress scales were used in 16.9%, and no psychological scales were reported in 28.8%. Fewer than half the studies (42.4%) documented a change in a psychological outcome. The majority of analyzed studies failed to describe how psychological symptoms were identified and treated, which discipline on the team provided the treatment, and whether psychological symptoms improved as a result of the intervention. Future research evaluating the effects of palliative care interventions on psychological symptoms will benefit from using reliable and valid psychological outcome measures and providing specificity regarding the psychological components of the intervention and who provides it.

  7. The psychologizing of Chinese healing practices in the United States.

    Science.gov (United States)

    Barnes, L L

    1998-12-01

    This paper explores ways in which Chinese healing practices have undergone acculturation in the United States since the early 1970s. Reacting to what is perceived as biomedicine's focus on the physiological, those who describe themselves as favoring a holistic orientation often use the language of "energy blockage" to explain illness, whether thought of as "physical," "emotional," or "spiritual." Acupuncture in particular has been appropriated as one modality with which to "unblock" such conditions, leading to its being used by some practitioners in conjunction with more psychotherapeutic approaches which include valuing the verbalizing of feelings. Some non-Chinese practitioners in the United States, returning to older Chinese texts to develop "an American acupuncture," are reinserting diagnoses eliminated from Traditional Chinese Medicine (TCM) by the People's Republic of China as "superstition." The assumption has been that many such diagnostic categories refer to psychological or spiritual conditions, and therefore may be useful in those American contexts which favor this orientation. Among these categories are those drawn from traditions of demonology in Chinese medicine. What was once a religious category in China turns psychological in the American setting. At the same time, many who use these terms have, since the late 1960s, increasingly conflated the psychological and the religious, the latter being reframed as "spiritual." Thus, this indigenization of Chinese practices is a complex synthesis which can be described as simultaneously medical, psychotherapeutic, and religious.

  10. Hospital nurses' individual priorities, internal psychological states and work motivation.

    This study looks to describe the relationships between hospital nurses' individual priorities, internal psychological states and their work motivation. Connections between hospital nurses' work-related needs, values and work motivation are essential for providing safe and high quality health care. However, there is insufficient empirical knowledge concerning these connections for the practice development. A cross-sectional empirical research study was undertaken. A total of 201 registered nurses from all types of Estonian hospitals filled out an electronic self-reported questionnaire. Descriptive statistics, Mann-Whitney, Kruskal-Wallis and Spearman's correlation were used for data analysis. In individual priorities, higher order needs strength were negatively correlated with age and duration of service. Regarding nurses' internal psychological states, central hospital nurses had less sense of meaningfulness of work. Nurses' individual priorities (i.e. their higher order needs strength and shared values with the organization) correlated with their work motivation. Their internal psychological states (i.e. their experienced meaningfulness of work, experienced responsibility for work outcomes and their knowledge of results) correlated with intrinsic work motivation. Nurses who prioritize their higher order needs are more motivated to work. The more their own values are compatible with those of the organization, the more intrinsically motivated they are likely to be. Nurses' individual achievements, autonomy and training are key factors which influence their motivation to work. The small sample size and low response rate of the study limit the direct transferability of the findings to the wider nurse population, so further research is needed. This study highlights the need and importance to support nurses' professional development and self-determination, in order to develop and retain motivated nurses. It also indicates a need to value both nurses and nursing in

  13. The Concept of Human Functional State in Russian Applied Psychology

    Directory of Open Access Journals (Sweden)

    Anna B. Leonova

    2009-01-01

    Full Text Available The concept of human functional states (HFS is considered in the framework of activity regulation approach developed in Russian applied psychology. Aimed at the analysis of changes in regulatory mechanisms of on-going activity, structural methods for multilevel assessment of workers’ states are discussed. Three different strategies of data integration are proposed regarding the types of essential practical problems. Their usability is exemplified with the help of two empirical studies concerned with reliability of fire-fighters’ work in the Chernobyl Zone and effects of interruptions in computerized office environment. A general framework for applied HFS research is proposed in order to develop new ecologically valid psychodiagnostic procedures that can help to create efficient stress-management programs for enhancing human reliability and performance in complex job environment.

    Only a few scales measure confidence within sport; however, these scales are insufficient to measure confidence after athletic injuries. Therefore, better measures are needed to determine the psychological readiness of injured athletes to return to sport participation. To develop a scale that measures the psychological readiness of injured athletes to return to sport participation and to provide preliminary evidence of reliability and validity for the scale. The Delphi method was used to develop the Injury-Psychological Readiness to Return to Sport scale (I-PRRS). Two 1-way analyses of variance with repeated measures and 6 Pearson product moment correlations were computed to help validate the scale. Athletic training clinics at 3 National Collegiate Athletic Association (NCAA) schools. Four certified athletic trainers (ATs) and professors of Commission on Accreditation of Athletic Training Education-accredited athletic training programs and 3 NCAA Division III coaches made up a panel of experts that participated in the Delphi portion of the study to develop the I-PRRS. In the second part of the study, 22 injured athletes, who missed a minimum of 1 week of practice, from 3 NCAA schools in Divisions II and III were surveyed along with their respective ATs. The injured athletes and ATs participated in the validation of the I-PRRS. The injured athlete completed the Profile of Mood States (POMS) short form and the I-PRRS shortly after injury, before returning to the first practice, before returning to competition, and immediately after competition. The respective AT completed the I-PRRS before and after competition. The I-PRRS is a 6-item scale that measures the psychological readiness of injured athletes to return to sport, and the POMS short form is a 30-item scale that measures mood states. I added the negative moods of the POMS and subtracted the positive moods of the POMS to calculate a Total Mood Disturbance (TMD) score. The I-PRRS scores were negatively

    The great progress that has been made in application of dialyses lets the patients with chronic kidney disorders live in satisfactory somatic state for many years. The patients' quality of life becomes a more often raised issue. The psychological problems accompanying this form of treatment have many aspects that are worth paying attention to, e.g., mood reduction or resignation attitude. The symptoms that usually occur in depression gain special significance in the case of patients treated with dialyses. Loss of appetite in these patients may lead to a prompt occurrence of metabolic disorders. Mood reduction may result in willingness to give up treatment. Depression symptoms are a significant early indication of bad prognosis as to survival of patients treated with dialyses.

    The PainCAS is a web-based clinical tool for assessing and tracking pain and opioid risk in chronic pain patients. Despite evidence for its utility within the clinical setting, the PainCAS scales have never been subject to psychometric evaluation. The current study is the first to evaluate the psychometric properties of the PainCAS Interference with Daily Activities, Psychological/Emotional Distress, and Pain scales. Patients (N = 4797) from treatment centers and hospitals in 16 different states completed the PainCAS as part of routine clinical assessment. A subsample (n = 73) from two hospital-based treatment centers also completed comparator measures. Rasch Rating Scale Models were employed to evaluate the Interference with Daily Activities and Psychological/Emotional Distress scales, and empirical evaluation included assessment of dimensionality, discrimination, item fit, reliability, information, and person-to-item targeting. Additionally, convergent and discriminant validity were evaluated through classical test theory approaches. Convergent validity of the Pain scales was evaluated through correlations with corresponding comparator items. One Interference with Daily Activities item was removed due to poor functioning and discrimination. The retained items from the Interference with Daily Activities and Psychological/Emotional Distress scales conformed to unidimensional Rasch measurement models, yielding satisfactory item fit, reliability, precision, and coverage. Further, results provided support for the convergent and discriminant validity of these two scales. Convergent validity between the PainCAS Pain and BPI Pain items was also strong. Taken together, results provide strong psychometric support for these PainCAS Pain scales. Strengths and limitations of the current study are discussed.

    2011-01-01

    Rating scales are standard instruments in psychology. They force the research participant to provide a numerical estimate of an assumed “degree” of some characteristic along a linear scale. We prove that such numerical estimates are artifacts based on unknown psychological processes that are used...... in the making of a rating. Psychology’s current use of rating scales entails reliance upon unexplored and abbreviated introspection. It superimposes upon the rater the use of real numbers for the subjective construction of the ratings. The axiomatic superimposition of the notion of “degree” of subjective...... in terms of the study of microgenesis of rating processes allows psychology access to the reality of the workings of the human mind....

    1991-01-01

    The relationship between moderate exercise training (five 45 min sessions/week, brisk walking at 62 beta +/- 2% VO2max for 15 weeks, psychological well-being and mood state was investigated in a group of 35 sedentary, mildly obese women. A 2 (exercise (EX) (N = 18), and nonexercise (NEX) (N = 17) groups) x 3 (baseline, 6-week, 15-week testing sessions) factorial design was used with data analyzed using repeated measures ANOVA. Four psychological tests were administered: Daily Hassles Scale (DHS), General Well-being Schedule (GWB), Spielberger State Anxiety Inventory (S-Anxiety), and Profile of Mood States (POMS). The EX and NEX groups had significantly different patterns of change over time for GWB total scores [F(2,66) = 5.72, p = 0.005] and the GWB subscales 'energy level' and 'freedom from health concern or worry'. Scores for the EX group were elevated at both 6 and 15 weeks. General well-being total scores and subscale 'energy level' scores were significantly correlated with improvement in submaximal cardiorespiratory fitness (r = -0.41, p = 0.014; r = -0.40, p = 0.017, respectively). Exercise training also had a significant effect on frequency but not intensity of DHS scores, and S-Anxiety, with a significant decrease seen in the EX group at 6 weeks but not 15 weeks. Profile of Mood States scores were not significantly related to exercise training. These data support the results of other studies that have reported improvement in general psychological well-being with exercise training.

    2010-01-01

    Full Text Available Metric characteristics of Slovene version of the Ryff's Scales of Psychological Well-Being (RPWB; Ryff, 1989 were analysed. The scales are based on the theoretical model of psychological well-being and refer to six areas of positive functioning of individual: self-acceptance, environmental mastery, personal growth, meaning in life, and autonomy. The construct validity of the original 84- item version of the RPWB was examined on the sample of 423 participants. Results of the multigroup component analysis indicate the problematic discriminative validity of some scales. Correlations with the Big Five are in accordance with our assumptions, and confirmed construct validity of the scales. Factor validity of the 25-item version of the RPWB was examined on the internet sample of 481 participants. Results indicate worse metric characteristics compared to the 84-item version. Because different versions of the scales (3-item, 4-item, 9-item, 14-item per scale version are in use, it would be reasonable to examine scales with more than 4 and less than 14 items per scale also in Slovene sample.

    Full Text Available Psychology students are currently weakly organized in Argentina. The reasons for that maybe found in the circumstances of the local academic life and the changing social, economicand political realities the country went through in the last decades. In the meantime, thequality of the Psychology courses is poorer than its neighbouring Latinamerican countriesand it’s even more distanced from the world centres of academic reference. Nowadays,there are two developments encouraging the reflection and action of the students about that: the COBAND Project and the National Association of Psychology Students of Argentina (ANEPSI Argentina. Besides that, a magazine is published to endorse the creation of scientific reading habits among students. However, many challenges appear on the way to a Psychology more responsible to science and society.

    2014-06-01

    The influence of psychological factors on cigarette dependence often surpasses the direct effects of the nicotine itself. Researcher opinions on the nature and extent of psychological contributors to cigarette dependence vary widely. This study develops and psychometrically tests the Psychological Cigarette Dependence Scale (PCDS) for male smokers in Taiwan. The PCDS was developed using domain identification, individual interviews for item generation, expert reviews, and testing for construct validity and instrument stability. After initial item analysis, the PCDS was tested for concurrent and construct validity and reliability on 256 adult male smokers recruited from community centers, trade and business organizations, private companies, and factories in southern Taiwan. Participants were limited to adult men because female smokers are a small (4.1%) proportion of the female population in Taiwan and thus are difficult to recruit in statistically significant numbers. Exploratory factor analysis showed that lifelong binding and health concerns are the two predominating factors addressed by the 37-item PCDS. The PCDS correlated positively with the Fagerstrom questionnaire (r = .54, p psychological cigarette dependence. Assessment results may help nursing professionals focus on smoking cessation interventions that are tailored to the patterns and severity of patients' psychological cigarette dependence.

  15. Transactional stress and coping theory in accounting for psychological states measures

    Directory of Open Access Journals (Sweden)

    V. Buško

    2007-08-01

    Full Text Available The paper examines a relative predictive value of some stable individual attributes and the processes of cognitive appraisals and coping with stress in accounting for specific components of anxiety state measures. Self-report instruments for the measurement of selected psychological constructs, i.e. perceived incompetence, externality, stress intensity and duration, situation-specific coping strategies, and the two anxiety state components, were taken in a sample of 449 male military basics trainees, ranging in age from 18-27. Hierarchical multiple regression analyses showed that the set of predictors employed could account for statistically, as well as theoretically and practically a significant part of variance in cognitive anxiety component (45,5%, and in visceral-emotional component (32,2% of the anxiety state. The extent of anxiety reactions assessed by both scales could primarily be explained by general perception of personal incompetence, as a relatively stable dimension of general self-concept. Of the ways of coping examined, reinterpretation of stressful events was the only strategy contributing to low level, whereas passivization, wishful thinking, and seeking social support contributed to higher levels of anxiety measured by both scales. The results give partial support to the basic hypotheses on the mediating role of coping in the relationships among particular components of the stress and coping models.

    1992-02-01

    A large sample (N = 483) of community-living adults (M age = 23.6 years) responded to questions about the frequency and adequacy of emotional, practical, and informational support during the past month from three sources-confidants, peers, and supervisors-using the Multi-Dimensional Support Scale. Factor analysis was used to distinguish meaningful regularities in item responses, and the resulting five scales have high internal reliability. Scores correlated significantly with measures of self-esteem, depressive affect, and psychological disturbance according to the General Health Questionnaire. To investigate what contribution support measures could make to the prediction of psychological well-being, hierarchical regression analyses were carried out with stressors entered first and support scores entered second. As expected, respondents' psychological well-being was related to their level of life stress; however, the addition of social support measures doubled the explained variance in measures of psychological well-being. The support measure with the strongest association with well-being was the frequency of supportive behaviors toward the respondent by close family and friends.

    2016-06-01

    There is still an open debate about the utility of social desirability indicators. This report systematically reviewed the use of social desirability scales in studies addressing social desirability in clinical psychology. A systematic review (January 2010-March 2015) was conducted, including 35 studies meeting the inclusion criteria of being published in peer-reviewed journals and describing quantitative findings about an association of social desirability with clinical psychology variables using a cross-sectional or longitudinal design. Social desirability was associated with self-reports of various clinical-psychological dimensions. Most of the included studies treated social desirability as a 1-dimensional variable and only 10 of 35 disentangled the impression management and self-deception components. Although theoretical literature does not consider social desirability a mere response bias, only 4 of the reviewed articles controlled for the possible suppressor effect of personality variables on social desirability, while the majority focused upon the stylistic (response bias) rather than the substantive (personality) nature of this construct. The present review highlighted some limitations in the use of social desirability scales in recent clinical psychology research and tried to offer a few suggestions for handling this issue. © 2016 Wiley Periodicals, Inc.

    Full Text Available This study explored the state of psychological well-being and academic optimism in relation to university tasks among one hundred sixty-nine (169 professors in selected UAE universities, utilizing mixed quantitative and qualitative research approaches. The quantitative aspect primarily employed descriptive correlation method which used quantifiable data through survey instruments on psychological well-being, academic optimism, and university tasks. The qualitative analysis was used through a focused group discussion among nineteen (19 key informants. Six (6 areas of psychological wellbeing: autonomy, environmental mastery, personal growth, positive relations, purpose in life, and selfacceptance were measured through the Ryff's Scales of Psychological Well-Being. Academic optimism scale measured three (3 subscales: efficacy, trust, and academic emphasis. University tasks were categorized into three (3 major areas: student centered work, professional development work, and community centered work. The moderator variables considered were age, gender, length of teaching experience, length of experience in the UAE, and area of specialization. The results showed that the participants tend towards high scores in the subscales of autonomy, self-acceptance, and purpose in life. The academic optimism scale showed prominent high scores in efficacy and trust. Among the university tasks, student-centered work was the most fulfilled. Using the focused-group discussion, most expat university professors lament on the lack of time, management support, and lack of funding to pursue professional development, particularly research and publication. The regression analysis showed that there is a significant correlation between psychological well-being and academic optimism. Both psychological well-being and academic optimism predicts fulfillment of university tasks.

    This study validates the Portuguese version of the psychological effects of the relational job characteristics scale among hospital nurses in Portugal and Brazil. Increasing attention has been given to the social dimension of work, following the transition to a service economy. Nevertheless, and despite the unquestionable relational characteristics of nursing work, scarce research has been developed among nurses under a relational job design framework. Moreover, it is important to develop instruments that study the effects of relational job characteristics among nurses. We followed Messick's framework for scale validation, comprising the steps regarding the response process and internal structure, as well as relationships with other variables (work engagement and burnout). Statistical analysis included exploratory factor analysis and confirmatory factor analysis. The psychological effects of the relational job characteristics scale provided evidence of good psychometric properties with Portuguese and Brazilian hospital nurses. Also, the psychological effects of the relational job characteristics are associated with nurses' work-related well-being: positively with work engagement and negatively concerning burnout. Hospitals that foster the relational characteristics of nursing work are contributing to their nurses' work-related well-being, which may be reflected in the quality of care and patient safety. © 2017 John Wiley & Sons Ltd.

    The neuropsychiatric sequelae of chronic Lyme disease remains unclear. This study sought to characterize the psychological status of a group of participants who met criteria for post-Lyme syndrome (PLS). These measures were then used to examine the influence of psychological status on neuropsychological performances. Thirty PLS participants completed a structured psychiatric interview, the Positive and Negative Affect Schedule, the Lyme Symptom Checklist, and a battery of neuropsychological tests. As a group, the PLS participants did not appear to have an elevated incidence of psychiatric disorders, and psychiatric history was not useful for understanding neuropsychological performances or symptom reports. The mood of the PLS participants was characterized by lowered levels of positive affect (PA) and typical levels of negative affect. This combination can be distinguished from depression and is consistent with previous findings of affect patterns in individuals with chronic fatigue syndrome. PA was also linked to both total symptom severity and severity of cognitive complaints, but not to duration of illness, neurological manifestations at initial diagnosis, or treatment history. Relative to published normative data, neuropsychological performances were not in the impaired range on any measure. Neither psychological status nor symptom report were useful for understanding any aspect of cognitive functioning. It is concluded that decreased PA is the most useful marker of psychological functioning in PLS.

    The aim of this study was to test the reliability and validity of the Psychological Conditions Scale (PCS), a measure of drivers of engagement in hospital-based nurses. Research suggests drivers of engagement are positive links to patient, employee, and hospital outcomes. Although this scale has been used in other occupations, it has not been tested in nursing. A cross-sectional, methodological study using a convenience sample of 200 nurses in a large Magnet® hospital in New Jersey. Cronbach's α's ranged from .64 to .95. Principal components exploratory factor analysis with oblique rotation revealed that 13 items loaded unambiguously in 3 domains and explained 76% of the variance. Mean PCS scores ranged from 3.62 to 4.68 on a 5-point Likert scale. The scale is an adequate measure of drivers of engagement in hospital-based nurses. Leadership efforts to promote the facilitators of engagement are recommended.

    Definitions of psychological abuse are reviewed and a new definition proposed, operationalized as an extension of an existing measure of childhood, the Childhood Experience of Care and Abuse (CECA). This semistructured, investigator-based interview is designed for use with adults to collect retrospective accounts of childhood adverse experience. The CECA extension identifies nine subtypes of psychological abuse, with a single global severity rating. The definition is clearly differentiated from other adverse experiences with emotionally abusive elements such as parental antipathy (hostile parenting), neglect, and role reversal. Examples are given. A community-based series of 301 women were interviewed using the extended CECA to gather a range of experiences of childhood maltreatment on which to devise the new measure. Interrater reliability was satisfactory, and several features of psychological abuse were examined, including its prevalence, frequency, and the characteristics of the abused child and perpetrator. The new scale is discussed in terms of its potential use not only by researchers but also by practitioners such as clinicians and social workers in the child protection field in order to more accurately identify and assess multiples of abuse in childhood. A companion article (Bifulco, Moran, Baines, Bunn, & Stanford, 2002) examines the relationship of psychological abuse to adult major depression.

  7. Social welfare as small-scale help: evolutionary psychology and the deservingness heuristic.

    Petersen, Michael Bang

    2012-01-01

    Public opinion concerning social welfare is largely driven by perceptions of recipient deservingness. Extant research has argued that this heuristic is learned from a variety of cultural, institutional, and ideological sources. The present article provides evidence supporting a different view: that the deservingness heuristic is rooted in psychological categories that evolved over the course of human evolution to regulate small-scale exchanges of help. To test predictions made on the basis of this view, a method designed to measure social categorization is embedded in nationally representative surveys conducted in different countries. Across the national- and individual-level differences that extant research has used to explain the heuristic, people categorize welfare recipients on the basis of whether they are lazy or unlucky. This mode of categorization furthermore induces people to think about large-scale welfare politics as its presumed ancestral equivalent: small-scale help giving. The general implications for research on heuristics are discussed.

    This project describes the development of the Resilient Systems Scales, created to address conceptual and methodological ambiguities in assessing the ecological systems model of resilience. Across a number of samples (total N = 986), our findings suggest that the Resilient Systems Scales show equivalence to a previously reported assessment (Maltby, Day, & Hall, 2015 ) in demonstrating the same factor structure, adequate intercorrelation between the 2 measures of resilience, and equivalent associations with personality and well-being. The findings also suggest that the Resilient Systems Scales demonstrate adequate test-retest reliability, compare well with other extant measures of resilience in predicting well-being, and map, to varying degrees, onto positive expression of several cognitive, social, and emotional traits. The findings suggest that the new measure can be used alongside existing measures of resilience, or singly, to assess positive life outcomes within psychology research.

    Full Text Available Background and aims. Parents’ empowerment is advocated to promote and preserve an informed and autonomous decision regarding their children’ immunization. The scope of this study is to develop and evaluate the psychometric properties of an instrument to measure parents’ psychological empowerment in their children’s vaccination decision and propose a context-specific definition of this construct. Materials and Methods. Grounding in previous qualitative data, we generated an initial pool of items which was later content and face validated by a panel of experts. A pretest allowed us to reduce the initial pool to 9 items. Convergent and discriminant validity measures included the General Self-Efficacy Scale, a Psychological Empowerment Scale, and the Control Preference Scale. Vaccination-related outcomes such as attitude and intention were also included. Results. Principal Component Analysis revealed a 2-factor structure, with each factor composed of 2 items. The first factor concerns the perceived influence of one’s personal and family experience with vaccination, while the second factor represents the desire not to ask other parents about their experience with vaccination and their lack of interest in other parents’ vaccination opinion. Conclusions. In light of its association with positive immunization- related outcomes, public health efforts should be directed to reinforce parents’ empowerment.

    Full Text Available Orientation: South African studies investigating the factor structure of the Ryff Scales of Psychological Well-being (RPWB are needed to ensure that the instrument is valid and reliable within the South African context.Research purpose: The objective of this study was to investigate the factor structure of the RPWB within two South African samples. Motivation for the study: Although a substantial number of studies have been undertaken, results regarding the factor structure of the Ryff Scales of Psychological Well-Being are inconclusive. There is a dearth of information in relation to South African studies examining the scales’ factor structure.Research design, approach and method: A quantitative research approach using a crosssectional field survey design was utilised. An adult working group (n = 202 was selected using convenience sampling, and a student group (n = 226 was selected by means of purposive non-probability sampling. An Exploratory Factor Analysis and a Confirmatory Factor Analysis were conducted to examine the factor structure.Main findings: The preferred model was a two-factor model where all the positively worded items were grouped in the first factor and all the negatively worded items were grouped in the second factor.Practical/managerial implications: The factor structure of the original RPWB was not satisfactorily replicated and remains seemingly unsettled. The utility of negatively worded items should be considered carefully, and alternatives such as mixed response options and phrase completion should be explored. The scales should be used with caution.Contribution/value-add: The study contributes to the literature concerning the factor structure of the RPWB with an emphasis on the South African context. It contributes to ensuring that researchers and practitioners use a valid and reliable instrument when measuring psychological well-being.

    Ability testing has been criticized because understanding of the construct being assessed is incomplete and because the testing has not yet been satisfactorily improved in accordance with new knowledge from cognitive psychology. This article contributes to the solution of this problem through the application of item response theory and Susan Embretson's cognitive design system for test development in the development of a fluid intelligence scale. This study is based on findings from cognitive psychology; instead of focusing on the development of a test, it focuses on the definition of a variable for the creation of a criterion-referenced measure for fluid intelligence. A geometric matrix item bank with 26 items was analyzed with data from 2,797 undergraduate students. The main result was a criterion-referenced scale that was based on information from item features that were linked to cognitive components, such as storage capacity, goal management, and abstraction; this information was used to create the descriptions of selected levels of a fluid intelligence scale. The scale proposed that the levels of fluid intelligence range from the ability to solve problems containing a limited number of bits of information with obvious relationships through the ability to solve problems that involve abstract relationships under conditions that are confounded with an information overload and distraction by mixed noise. This scale can be employed in future research to provide interpretations for the measurements of the cognitive processes mastered and the types of difficulty experienced by examinees.

    Robot-assisted treadmill training is an established intervention used to improve walking ability in patients with neurological disorders. Although it has been shown that attention to the task is a key factor for successful rehabilitation, the psychological state of patients during robot-assisted gait therapy is often neglected. We presented 17 nondisabled subjects and 10 patients with neurological disorders a virtual-reality task with varying difficulty levels to induce feelings of being bored, excited, and overstressed. We developed an approach to automatically estimate and classify a patient's psychological state, i.e., his or her mental engagement, in real time during gait training. We used psychophysiological measurements to obtain an objective measure of the current psychological state. Automatic classification was performed by a neural network. We found that heart rate, skin conductance responses, and skin temperature can be used as markers for psychological states in the presence of physical effort induced by walking. The classifier achieved a classification error of 1.4% for nondisabled subjects and 2.1% for patients with neurological disorders. Using our new method, we processed the psychological state data in real time. Our method is a first step toward real-time auto-adaptive gait training with potential to improve rehabilitation results by optimally challenging patients at all times during exercise.

    The purpose of this research was to examine the psychometric properties of a Spanish translation of the Flow State Scale (FSS; Jackson & Marsh, 1996). This instrument is used to assess the Flow State in participants of physical activity, although it can be adapted to other contexts (such as work, educational contexts, etc.). This construct can be considered the optimal psychological state to carry out an activity, being closely related to motivation and personal enjoyment (Csikszentmihalyi, 1997). A sample of 2036 athletes was recruited from diverse sports activities. The results revealed satisfactory validity and internal consistency of the instrument, obtaining a factor model made up of a main factor and nine subscales. The correlations between motivational orientations and the flow state are highlighted. The Spanish translation of this instrument is found to be acceptable, with similar psychometric properties as the original scale, although future research in other contexts is needed to support these outcomes.

    Objective: To investigate the changes in psychological state after occupational exposure in the AIDS occupational exposure population and related influencing factors, and to provide baseline data and a basis for related departments to conduct mental health prevention and intervention for personnel with occupational AIDS exposure. Methods: AIDS risk assessment was performed for all personnel with occupational AIDS exposure in 2014 in Nanning, China, and the Symptom Checklist-90 (SCL-90) psychological scale was used for psychological state evaluation at 24 hours, 1 week, and 3 months after occupational exposure in all persons who met the research criteria. Results: Most of the persons with occupational AIDS exposure came from secondary and tertiary hospitals (85%) , and nurses accounted for the highest percentage (78.3% ). The age ranged from 21 to 50 years, and the mean age was 31.02 ± 7.92 years. The persons with occupational AIDS exposure aged 20~29 years accounted for the highest percentage (51.6%) , and most persons (76.7%) graduated from junior colleges. Compared with the adult norm, there was significant increases in the total psychological score and the number of positive items after occupational exposure (P<0.05). The scores of all items at 24 hours were significantly higher than those at the other time points, and the scores of all items gradually decreased over time (F=227.24, 267.57, and 287.46, P<0.05). Compared with the adult norm, there were significant increases in the factor points at 24 hours and significant reductions in the factor points at 3 months (P<0.05). Compared with those at 24 hours, the factor scores at 3 months decreased significantly (P<0.05). Conclusion: Occupational AIDS exposure affects the mental status of related personnel, and the mental status at 24 hours after exposure is poor. Related departments should provide corresponding psychological counseling for the occupational exposure population at different exposure times.

    The Kessler Psychological Distress Scale has been widely used in assessing psychological distress among general and clinical populations from different cultural backgrounds. To our knowledge, however, researchers have not yet validated any translated versions in Arabic. The purpose of this study was to test the reliability and validity of Arabic translations of the ten item (K10) and six item (K6) versions among public sector employees in the Occupied Palestinian Territories. As part of a larger research project on life satisfaction, researchers collected data from 234 Palestinian social workers in June and July of 2016. The survey included several mental health measures, including the K10, which were translated from English to Arabic by an experienced language expert. In the current study, we tested reliability by measuring internal consistency using Cronbach's alpha coefficient. Next, we assessed factor structure using variance-covariance matrix with maximum likelihood estimation. Confirmatory factor analysis was performed to examine three competing models: unidimensional K10 model, unidimensional K6 model and two-factor K6 model. Fit indices and parameter estimates were reported. Last, convergent validity was examined by assessing correlations with Generalized Anxiety Disorder (GAD-7) and Somatic Symptoms Scale (SSS-8). The mean scores for the K6 and K10 were, respectively, 12.87 (SD = 4.02) and 21.8 (SD = 6.7), indicative of mild to moderate levels of distress. Scale reliability analysis showed satisfactory results on both K6 and K10 versions (Cronbach's α = .81 (K6) and .88 (K10)). Among three competing models, the two-factor K6 scale demonstrated the best model fit with high factorial correlations (r = .60, p Arabic-speaking populations.

    There is growing interest in the effects of psychological states on human performance, especially with those who have suffered debilitating injury and are attempting to return to sport (RTS). Current research methods measure psychological states through validated questionnaires; however, these outcomes only allow for subjective assessment and may be unintentionally biased. Application of objective neurocognitive measures correlated with psychological states will advance understanding of injury outcomes by identifying human behavior and avoiding vague assumptions from subjective measures.

    The purpose of this study was to reconstruct the psychological state of suicidal subjects at the time of the execution of the gesture according to their thoughts, their emotions, their actions, their fantasy life and consciousness. Thirty-three adult subjects agreed, just days after their suicide attempt, to answer the Interview Method for Suicidal Acts (IMSA). This object of this semi-structured interview is to invite the suicidal to reconstruct mentally and chronologically their suicide attempt. IMSA can follow the thoughts, behavior, consciousness, emotions and activity of the suicidal scenario by helping the patient to reconstruct the phenomenology of his/her actions until the final suicidal gesture. The data were processed using the method of Classification TwoStep on SPSS, based on Schwarz Bayesian criterion. The results highlight three main types of psychological state: (1) a "kinesthetic" psychological state (called "type K") is characterized by a rupture between the subjective sensation of motor movement and effective motility (motor automatism), the presence of a dissociative state, an "empty" feeling of thought and the absence of an external triggering factor; (2) a "cognitive" psychological state (called "type C") is characterized by a significant reflection on the decision to die and infiltration of the morbid thought, an intense fantasy life around the suicidal scenario, a clear state of consciousness, and an absence of loss of motor control; (3) an "emotional" psychological state (called "type E") is characterized by confusing and chaotic emotional processes, the emergence of a dissociative state, and a significant impact of external events on the onset of the suicide attempt. This classification of suicide attempts allows us to identify the different combinations of the suicidal process and opens up new therapeutic strategies. Copyright © 2013 L’Encéphale, Paris.

    Full Text Available Correlations between values of components of subjective psychological experiences and states in 26 male football referees before the match and after the match were explored using factor analysis. For evaluation of subjective psychological experiences and states the standardized questionnaire SUPSO was used. The questionnaire was filled in twice by refer ees: before the match and immediately after the match. Four most important factors were described and named. The first factor was called "tendency to discomfort". It relates to referee ́s current mental state being probably a reflection of long - term negativ e circumstances in referee ́s life. It is neither related to the completed match, nor referee ́s temperament . The second factor was called "depression from failure" and it is connected directly to the completed match. It is probably determined by current ref eree ́s physical and mental conditions . The third and fourth factors proved to be consequences of temperament of referees. In conclusion, the two most important factors of current mental state of football referee during the game can probably be influenced b y a systematic psychological preparation . Psychological preparation should therefore become an effective part of the pre - match preparation of football referees.

    The 8.0-magnitude earthquake that struck Wenchuan County in Sichuan was the most destructive earthquake to hit China since the People's Republic of China was founded in 1949. It caused great environmental harm and property damage, and brought considerable psychological stress and emotional problems to many in the population. This study was designed to investigate the psychological state of nursing students studying at a university located within the Wenchuan earthquake zone. Nurses were recruited using a striated cluster sampling approach. The study was conducted using a self-designed questionnaire, Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS), Social Support Rating Scale (SSRS) and Coping Style Questionnaire. Most (68.8%) participants lacked sufficient knowledge regarding the earthquake, and the social support condition of college nursing students was lower than the population average (p anxiety and depression was higher than the population average (p students in different class years in terms of study variables was identified. Nursing students in areas affected by the Wenchuan earthquake suffer from anxiety and depression disorders. Adequate social support represents an important intervention needed to maintain and enhance their mental health.

  11. New directions in the psychology of optimal performance in sport: flow and clutch states.

    Swann, Christian; Crust, Lee; Vella, Stewart A

    2017-08-01

    Csikszentmihalyi's conceptualisation of flow is the primary framework for understanding the psychology of optimal experience and performance in sport. However, emerging evidence suggests a more dynamic, multi-state perspective. This review focuses primarily on recent studies highlighting a second, overlapping 'clutch' state which - in addition to flow - underlies optimal performance in sport. We also examine how the nature of goals ('open' or 'fixed') athletes pursue influence the experience of flow and clutch respectively. This new, integrated model of psychological states underlying optimal performance raises questions around conceptualisation and methodology employed in the field to date. These implications are outlined, and recommendations are provided for more critical and accurate measurement of both flow and clutch as overlapping, yet distinct, states.

    Full Text Available OBJECTIVES: Family members of patients in a vegetative state have relatively high rates of anxiety and distress. It is important to recognize the problems faced by this population and apply psychological interventions to help them. This exploratory study describes the psychological stress experienced by family members of patients in a vegetative state. We discuss the effectiveness of a psychological crisis intervention directed at this population and offer suggestions for future clinical work. METHODS: A total of 107 family members of patients in a vegetative state were included in the study. The intervention included four steps: acquisition of facts about each family, sharing their first thoughts concerning the event, assessment of their emotional reactions and developing their coping abilities. The Symptom Check List-90 was used to evaluate the psychological distress of the participants at baseline and one month after the psychological intervention. Differences between the Symptom Check List-90 scores at the baseline and follow-up evaluations were analyzed. RESULTS: All participants in the study had significantly higher Symptom Check List-90 factor scores than the national norms at baseline. There were no significant differences between the intervention group and the control group at baseline. Most of the Symptom Check List-90 factor scores at the one-month follow-up evaluation were significantly lower than those at baseline for both groups; however, the intervention group improved significantly more than the control group on most subscales, including somatization, obsessive-compulsive behavior, depression, and anxiety. CONCLUSION: The results of this study indicate that the four-step intervention method effectively improves the mental health of the family members who received this treatment and lessens the psychological symptoms of somatization, obsessive-compulsive behavior, depression and anxiety.

    Full Text Available Considering the importance of screening and identifying people at risk of mental disorders in order to determine the prevalence of mental disorders and carry out activities to the prevention and treatment, the present study aimed to compare psychological profiles of people based on MMPI-2’s scales according to birth order, age and educational level in general population of 18-80 years old. Current study is analytical- cross sectional. Statistical population included all Iranian people between 18 to 80 years old who had minimum 8 classes of education and had no history of mental illness or brain injury. Among this population, 1418 individuals were selected by ratio sampling method from Tehran, Isfahan, Mashhad, Tabriz and Shiraz cities and they were assessed by Minnesota Multiphase Personality Inventory (MMPI-2. Results showed there is significant difference between people according to their age in scales of L (Lying, D (Depression, Ma (Mania, Pt (Psychastenia, Sc(Schizophrenia, and Si(Social Introversion, and there was significant difference based on level of education in scales of F (Infrequency, K (Defensiveness, Pa (Paranoia, Pt (Psychastenia, Sc (Schizophrenia and Si (Social Introversion. However, there was no significant differences between individuals based on birth order in validity and clinical scale of MMPI-2. Education and age are important factors which can influence mental health. It can be inferred that people with high level of education in comparison of people with low educational level have fewer mental disorders and higher mental wellbeing. Furthermore, people of different ages show different patterns of mental disorders.

    The purpose of the study was to extend our understanding of the Kyoto Scale of Psychological Development (KSPD) by comparison with a parent-rated scale, the Kinder Infant Development Scale (KIDS). The participants of this study were 229 children aged 0-4, who were referred to the Developmental Evaluation Center of the National Center for Child Health and Development, due to a suspected developmental disorder/delay. The participants were divided into subgroups, depending on age and overall DQ. For each group separately, correlation analyses were conducted between the Developmental Quotient (DQ) of each KSPD domain and DQ of each KIDS subscale. For high DQ group, in all ages, the KSPD Postural-Motor (P-M) domain DQ demonstrated a high correlation with the KIDS Physical-Motor DQ, and at young ages, it was also found to be moderately or strongly associated with the KIDS Manipulation DQ. For high DQ group, the KSPD Cognitive-Adaptive (C-A) domain DQ was most consistently related to the KIDS Manipulation DQ, and was also moderately correlated with the KIDS Physical-Motor DQ, Receptive Language DQ, Social Relationship with Adults DQ, Discipline DQ, and Feeding DQ, depending on age. For high DQ group, the KSPD Language-Social (L-S) DQ most consistently showed a moderate or high correlation with the KIDS Receptive Language DQ and the Manipulation DQ, and also related to Physical-Motor DQ, Expressive Language DQ, Language Conception DQ, Social Relationship with Adults DQ, and Social Relationship with Children DQ for some age groups. The low DQ group demonstrated stronger relationships on many of the pairs of the DQ of a KSPD subdomain and the DQ of a KIDS subscale, regardless of the type of subdomains and subscales. For high DQ group, the KSPD P-M domain was consistently related to parent-reported physical/motor development, the C-A domain primarily reflected a child's fine motor skills and his/her ability to understand and follow verbal instructions provided by adults

    Full Text Available There is a growing need to assess the psychological outcomes of exercise referral and the National Institute of Health and Care Excellence has called for the routine assessment of life-quality. However, a quality of life scale specific to the requirements of exercise referral is currently unavailable. Therefore, the aim of this study was to produce a quality of life measure for this purpose. The Exercise Referral Quality of Life Scale is a 22-item measure comprising three domains: mental and physical health, injury pain and illness and physical activity facilitators. Exploratory factor analysis determined the initial factor structure and was subsequently confirmed by confirmatory factor analysis. Additional scale properties were also assessed. The scale contributes to the global need for improved consistent psychological outcome assessment of exercise referral.

    The purposes of this study were (1) to characterize psychological states and coping strategies after bereavement among spouses of cancer patients in Japan and (2) to explore the factors associated with psychological states in oncology settings. In March 2009, questionnaires to assess spouses' psychological states, coping strategies, and mental health states (GHQ-28) were sent after patients died at the National Cancer Center of Japan. To address the first purpose, exploratory factor analysis, gender comparison, and calculation of correlation with age, time since bereavement, and mental health states were conducted. Hierarchical regression analysis was conducted to address the second purpose. A total of 821 spouses experiencing bereavement for 7 months to 7 years participated in the study. Psychological states revealed three factor structures: "Anxiety/Depression/Anger", "Yearning", and "Acceptance/Future-Oriented Feelings". Coping strategies also revealed three factor structures: "Distraction", "Continuing Bonds", and "Social Sharing/Reconstruction". Coping strategies represented 18 % to 34 % of each factor associated with psychological states, whereas the characteristics of bereaved spouses and deceased patients represented 6 % and less than 6 %, respectively. More "Distraction and Social Sharing/Reconstruction" and less "Continuing Bonds" were significantly associated coping strategies for achieving "Acceptance/Future-Oriented Feelings" (p strategies after bereavement revealed three factor structures. Coping strategies was the primary, bereaved spouses' characteristics was the secondary, and deceased patients' characteristics was the tertiary factor associated with psychological states. Enhancing "Distraction" and "Social Sharing/Reconstruction", and reducing "Continuing Bonds" might be promising strategies for achieving positive psychological states of the bereaved.

    To estimate the prevalence of physician burnout, psychological distress, and its association with selected personal and practice characteristics among pediatric critical care physicians and to evaluate the relationship between burnout and psychological distress. Cross-sectional, online survey. Pediatric critical care practices in the United States. Pediatric critical care physicians. None. A nonrandom sample of 253 physicians completed an online survey consisting of personal and practice characteristics, the Maslach Burnout Inventory, and the General Health Questionnaire. Nearly half of the participants (49%; 95% CI, 43-55%; n = 124) scored high burnout in at least one of the three subscales of the Maslach Burnout Inventory and 21% reported severe burnout. The risk of any burnout was about two times more in women physicians (odds ratio, 1.97; 95% CI, 1.2-3.4). Association between other personal or practice characteristics and burnout was not evident in this study, while regular physical exercise appeared to be protective. One third of all participants (30.5%) and 69% of those who experienced severe burnout screened positive for psychological distress. About 90% of the physicians reporting severe burnout have considered leaving their practice. Burnout is high among pediatric critical care physicians in the United States. About two thirds of the physicians with severe burnout met the screening criteria for psychological distress that suggests possible common mental disorders. Significant percentages of physicians experiencing burnout and considering to leave the profession has major implications for the critical care workforce.

    This study examined whether acculturation to American culture, maintenance of Chinese culture, and their interaction predicted Chinese immigrant parents' psychological adjustment and parenting styles. We hypothesized that American orientation would be associated with more positive psychological well-being and fewer depressive symptoms in immigrant mothers, which in turn would be associated with more authoritative parenting and less authoritarian parenting. The examination of the roles of Chinese orientation and the interaction of the 2 cultural orientations in relation to psychological adjustment and parenting were exploratory. Participants were 164 first-generation Chinese immigrant mothers in the United States (Mage = 37.80). Structural equation modeling was used to examine the direct and indirect effects of acculturation on psychological adjustment and parenting. Bootstrapping technique was used to explore the conditional indirect effects of acculturation on parenting as appropriate. American orientation was strongly associated with positive psychological well-being, which was in turn related to more authoritative parenting and less authoritarian parenting. Moreover, American and Chinese orientations interacted to predict depressive symptoms, which were in turn associated with more authoritarian parenting. Specifically, American orientation was negatively associated with depressive symptoms only at mean or high levels of Chinese orientation. Results suggest acculturation as a distal contextual factor and psychological adjustment as 1 critical mechanism that transmits effects of acculturation to parenting. Promoting immigrant parents' ability and comfort in the new culture independently or in conjunction with encouraging biculturalism through policy intervention efforts appear crucial for the positive adjustment of Chinese immigrant parents and children.

    Critically ill children are at risk for psychological sequelae following pediatric intensive care unit hospitalization. This article reports on the psychometric testing of the first self-report measure of psychological distress for 6-12-yr-old children post-pediatric intensive care unit hospitalization: The Children's Critical Illness Impact Scale. This 23-item scale takes approximately 15 mins for children to complete. Psychometric testing based on Classic Test Theory and guidelines for health measurement scale development. The pediatric intensive care units of four Canadian pediatric hospitals and the ear, nose, and throat clinic of one participating hospital. A total of 172 children (pediatric intensive care unit group, n = 84; ear, nose, and throat group, n = 88) aged 6-12 yrs and their parents. None. We assessed the factor structure, internal consistency, and test-retest reliability of the Children's Critical Illness Impact Scale and conducted contrasted group comparisons and convergent and concurrent validation testing. Fit indices and internal consistency were best for a three-factor solution, suggesting three dimensions of psychological distress: 1) worries about getting sick again, 2) feeling things have changed, and 3) feeling anxious and fearful about hospitalization. As expected, Children's Critical Illness Impact Scale scores were positively correlated with child anxiety and medical fear scores. The ear, nose, and throat group scores were higher than expected. Higher Children's Critical Illness Impact Scale scores in older children may reflect a better understanding of the situation and its complexity and meaning, and younger children's tendency to provide more positive self-evaluation. The Children's Critical Illness Impact Scale is a promising new self-report measure of psychological distress with demonstrated reliability and validation testing in 6-12-yr-old children post-pediatric intensive care unit hospitalization. This new measure has potential

    The Edinburgh Postnatal Depression Scale (EPDS) is a widely used instrument for screening for postpartum depression, but it might also detect anxiety symptoms. To investigate the factor structure of the EPDS administered immediately after delivery and to understand which factors predict a high EPDS score 3 months later. A cohort of 594 Italian mothers delivering a healthy baby at Versilia Hospital completed the EPDS at two points in time: 2 days after delivery (T0) and 3 months later (T1) by telephone interview. EPDS scores were higher at T0 than at T1. Overall, 15.7% of women at 2 days postpartum and 7.6% at 3 months later reported a score >9. The factor analysis of EPDS at T0 indicated a three-factor structure: "depression" (items 7-10), "anxiety" (items 3-6) and "anhedonia" (items 1-2). Anxious symptoms were quantitatively more important than depressive ones (mean 3.9 vs. 1.2) but tended to spontaneously ameliorate at T1, whereas total EPDS score at T1 was better predicted by depressive symptoms at T0 (discriminative ability 0.75 vs. 0.68). This study suggests that EPDS subscales immediately after delivery help understand the spectrum of maternal postpartum psychological problems. Anxious symptoms immediately after delivery are frequent but transient, linked probably to maternity blues or atypical depression, whereas the presence of depressive symptomatology at T0 suggests higher risk of later depressive disorders.

    Emotional intelligence is our capacity to acknowledge our own emotions, and the emotions of other people; it also has to do with the way emotions must be understood, and used productively. Given that an altered state of mind can have an impact on emotional intelligence, our objective was to correlate the psychological state with emotional intelligence in residents of gynecology, and obstetrics. We assessed 76 gynecology and obstetrics residents by using What's my M3 and TMMS-24 instruments, in order to know the influence of psychological state on emotional intelligence. In male students of second grade, there was a positive correlation between obsessive-compulsive disorder (OCD) and emotional attention (EA), and a negative correlation with emotional clarity (EC). In third grade males, anxiety, bipolar disorder, and posttraumatic stress disorder (PTSD) correlated positively with EA. In male students of fourth grade there was a positive correlation between OCD and EA. In second grade female students, depression correlated negatively with emotional repair (ER). In third grade female students anxiety, bipolar disorder, and PTSD correlated positively with EA. In fourth grade female students there was a negative correlation between depression and EA, and between anxiety, OCD, and PTSD with EC. Psychological status has a favorable impact on EA and a negative effect on EC and ER.

    Full Text Available There exists a lack of specific research methods to estimate the relationship between an organization and its employees, which has long challenged research in the field of organizational management. Therefore, this article introduces psychological distance concept into the research of organizational behavior, which can define the concept of psychological distance between employees and an organization and describe a level of perceived correspondence or interaction between subjects and objects. We developed an employee-organization psychological distance (EOPD scale through both qualitative and quantitative analysis methods. As indicated by the research results based on grounded theory (10 employee in-depth interview records and 277 opening questionnaires and formal investigation (544 questionnaires, this scale consists of six dimensions: experiential distance, behavioral distance, emotional distance, cognitive distance, spatial-temporal distance, and objective social distance based on 44 items. Finally, we determined that the EOPD scale exhibited acceptable reliability and validity using confirmatory factor analysis. This research may establish a foundation for future research on the measurement of psychological relationships between employees and organizations.

    Full Text Available Most of cancer patients are suffering from psychological distress which is under-diagnosed and under-treated in China. The purpose of this study is to evaluate the psychometric properties of a new screening instrument for psychological distress in cancer patients based on Chinese culture and personality traits. The scale was created after face-to-face interviews and focus group discussion of 50 medical staff and 30 cancer patients; the analysis of reliability and validity came from 1122 scales completed by cancer patients and non-cancer patients. Data was analyzed for internal consistency reliability, construct validity and discrimination validity in clinical practice. The internal consistency reliability of the scale was 0.906. Principal components factor analysis and structural equation modeling showed that the scale was comprised of four dimensions: depression, anxiety, interpersonal barrier and suspiciousness. The fit indices were χ2 (149 = 257.594, χ2/d?= 1.729, GFI = 0.927, NFI = 0.846, NNFI = 0.906, RMSEA = 0.061. These results indicated there were significant differences between cancer patients and non-cancer patients, with respect to the total scores, anxiety scores, interpersonal barrier scores and suspiciousness scores. The psychological distress scale is a new screening instrument for Chinese cancer patients, which is in line with the emphasis of Chinese culture.

    Full Text Available In recent years, the number of calls to the Helpline from people who are in crisis state, often with suicidal tendencies, has increased significantly. It is therefore particularly important that a helpline counselor had instant recognition skills of crisis state and the ability to quickly build a strategy for crisis counseling. The study described in the article was focused on crisis state structure of helpline subscribers using developed “Crisis state maps”. The subject of the study was the critical state of the individual subscribers seeking psychological help. We tested the assumption that the strategies and methods of psychological assistance are directly related to the features of crisis. We studied crisis state in 70 subscribers. Of these, 59 were females (12 to 66 years old and 11 males (11 to 40 years old. The average age of women was 34,5 years, of men – 23,4 years. The overall average age was 28,65 years. The study result was the portrait of typical helpline subscriber personality. We show the possible strategies of counseling

  10. Multiple time scales in multi-state models.

    In multi-state models, it has been the tradition to model all transition intensities on one time scale, usually the time since entry into the study ('clock-forward' approach). The effect of time since an intermediate event has been accommodated either by changing the time scale to time since entry to the new state ('clock-back' approach) or by including the time at entry to the new state as a covariate. In this paper, we argue that the choice of time scale for the various transitions in a multi-state model should be dealt with as an empirical question, as also the question of whether a single time scale is sufficient. We illustrate that these questions are best addressed by using parametric models for the transition rates, as opposed to the traditional Cox-model-based approaches. Specific advantages are that dependence of failure rates on multiple time scales can be made explicit and described in informative graphical displays. Using a single common time scale for all transitions greatly facilitates computations of probabilities of being in a particular state at a given time, because the machinery from the theory of Markov chains can be applied. However, a realistic model for transition rates is preferable, especially when the focus is not on prediction of final outcomes from start but on the analysis of instantaneous risk or on dynamic prediction. We illustrate the various approaches using a data set from stem cell transplant in leukemia and provide supplementary online material in R. Copyright © 2013 John Wiley & Sons, Ltd.

    Learning is a complex brain function operating on different time scales, from milliseconds to years, which induces enduring changes in brain dynamics. The brain also undergoes continuous “spontaneous” shifts in states, which, amongst others, are characterized by rhythmic activity of various frequencies. Besides the most obvious distinct modes of waking and sleep, wake-associated brain states comprise modulations of vigilance and attention. Recent findings show that certain brain states, particularly during sleep, are essential for learning and memory consolidation. Oscillatory activity plays a crucial role on several spatial scales, for example in plasticity at a synaptic level or in communication across brain areas. However, the underlying mechanisms and computational rules linking brain states and rhythms to learning, though relevant for our understanding of brain function and therapeutic approaches in brain disease, have not yet been elucidated. Here we review known mechanisms of how brain states mediate and modulate learning by their characteristic rhythmic signatures. To understand the critical interplay between brain states, brain rhythms, and learning processes, a wide range of experimental and theoretical work in animal models and human subjects from the single synapse to the large-scale cortical level needs to be integrated. By discussing results from experiments and theoretical approaches, we illuminate new avenues for utilizing neuronal learning mechanisms in developing tools and therapies, e.g., for stroke patients and to devise memory enhancement strategies for the elderly.

    Anxious and depressive symptoms are frequent in Systemic Sclerosis (SSc). Our objective is to assess their prevalence and association with district and global disability and psychological variables. 119 SSc patients were assessed by Hospital Anxiety Depression Scale (HADS). Clinical depression and anxiety were defined for HADS score cutoff ≥ 8. Patients were assessed for psychological symptoms (RSES, COPE-NIV), hand (HAMIS, CHFDS, fist closure, and hand opening) and face disability (MHISS, mouth opening), global disability, and fatigue (HAQ, FACIT). Both depression and anxiety in SSc are 36%. Depressive patients with comorbid anxiety have higher HADS-D score than patients with depression only (P = 0.001). HADS-A and -D are positively correlated with global disability, hands and mouth disability, fatigue, self-esteem and avoidance coping strategy, and, only HADS-A, also with social support (P anxiety correlate to local and global disabilities and psychological characteristics. Depressive patients with comorbid anxiety have higher level of depressive symptoms.

    In this study, we addressed the weak associations found in research between self-report measures and the Rorschach test (Exner, 1978, 1991), from the perspective of Bornstein's (2002) "process dissociation framework." Specifically, in the study, we focused on the associations between self-report measures of psychological distress and their corresponding Rorschach indexes while inspecting the moderating role of self-disclosure. A total of 59, nonpatient Israeli adults participated in a 2-session study. In the first session, they completed self-report scales measuring self-disclosure and psychological distress (suicidality, depression, and loneliness). In the second session, the Rorschach test was administered and coded. The participants were divided into high and low self-disclosure groups. A convergence between self-report and Rorschach measures of psychological distress was found only among high self-disclosers. In the discussion, we address the theoretical and clinical implications of these findings.

    It is generally recognized that the Chornobyl nuclear accident caused strong psychosocial stress affecting the entire population of Ukraine, primarily people involved in recovery operations. But what are the reasons? What is the struc ture of stressors? What are their social, medical and biological consequences, what are strategy and preventive meas ures? Issues that require special research and development. To study social and psychological state of the Chornobyl cleanup workers 1986-1987, and to determine regularities of changes and dangerous risk factors. On the basis of Polyclinic of Radiation Registry, NRCRM, we conducted sample epidemiolog ical study of social and psychological state of the Chornobyl clean up workers 1986-1987. We used method of inter viewing based on «questionnaire», specially developed for this purpose. The study was conducted in October 2013 - May 2015. The sample numbered 235 males aged 18-50 at the time of the accident. Their average age was (31.3 ± 5.3) years at the time of the accident and (58.9 ± 5.3) at the time of survey. The results revealed that the Chornobyl nuclear accident and its consequences caused strong social and psychological stress among clean up workers 1986-1987. We have identified a set of factors closely related to the Chornobyl accident, they have caused a sustainable development of mental syndrome - «Anxiety about their own health and the health of family members, especially children». The other set of stressors which are not closely relat ed to the Chornobyl accident but are the result of the social and economic, social and political situation in the coun try. However the former was found to be the cause of such a psychological state as «dissatisfaction with the com pleteness and quality of life». Social and psychological state of the Chornobyl clean up workers 1986-1987 is estimated as «poor» and it integrally can be characterized as a state of chronic psychosocial stress. Mental syndrome

    Assessment of state anxiety is frequently required in clinical and research settings, but its measurement using standard multi-item inventories entails practical challenges. Such inventories are increasingly complemented by paper-and-pencil, single-item visual analog scales measuring state anxiety (VAS-A), which allow rapid assessment of current anxiety states. Computerized versions of VAS-A offer additional advantages, including facilitated and accurate data collection and analysis, and applicability to computer-based protocols. Here, we establish the psychometric properties of a computerized VAS-A. Experiment 1 assessed the reliability, convergent validity, and discriminant validity of the computerized VAS-A in a non-selected sample. Experiment 2 assessed its sensitivity to increase in state anxiety following social stress induction, in participants with high levels of social anxiety. Experiment 1 demonstrated the computerized VAS-A's test-retest reliability (r = .44, p validity with the State-Trait Anxiety Inventory's state subscale (STAI-State; r = .60, p validity as indicated by significantly lower correlations between VAS-A and different psychological measures relative to the correlation between VAS-A and STAI-State. Experiment 2 demonstrated the VAS-A's sensitivity to changes in state anxiety via a significant pre- to during-stressor rise in VAS-A scores (F(1,48) = 25.13, p VAS-A a valuable self-rating tool for state anxiety. It may prove particularly useful for clinical and research settings where multi-item inventories are less applicable, including computer-based treatment and assessment protocols.

    The certainty of facing death and bereavement and the complex personal and societal issues involved argue for the importance of death education. The current study addresses a gap in knowledge by beginning to assess the extent of dying, death, and bereavement (DD&B) course offerings by U.S. psychology departments. This article reports on data collected from an initial survey of psychology departments in nine Midwestern states. Approximately 20% of respondents have offered a DD&B course in the last 5 years. Reasons for lack of DD&B courses include faculty and curriculum issues, as well as DD&B topics being covered elsewhere. These issues are discussed, and data are compared with DD&B course coverage in health-related fields.

    The purpose of this study was to assess the relationships between psychological characteristics such as anxiety and depression, quality of life (QOL) and coping style among patients with digestive cancer. The subjects were 85 in-patients who were scheduled to undergo initial surgery for gastrointestinal cancer. The following psychological tests were administered: Japanese versions of the Hospital Anxiety and Depression Scale, Zung's Self-Rating Depression Scale, the European Organization for Research and Treatment of Cancer (EORTC) QLQ C30 and the Coping Inventory for Stressful Situations. The first 3 tests were performed on three occasions: before surgery, before discharge and 6 months after discharge. The results showed that there was no change over the 3 test administration days for the average scores of anxiety and that the scores of depression increased from before surgery to before discharge and did not return to presurgery levels at 6 months after discharge. Changes in each subscale score of the EORTC QLQ C30 across the 3 days displayed two typical trends. Relationships between the abovementioned trends and individual coping styles showed that the higher the score of "emotion-oriented coping style," the greater the deterioration in QOL subscales. It was suggested that focusing on a patient's coping style, particularly emotion-oriented coping style, is important and that patients likely to adopt a more emotion-oriented coping style should receive special consideration.

    2017-12-01

    A new plasma state has been investigated [Akcay et al., Phys. Plasmas 24, 052503 (2017)], with a uniform applied axial magnetic field in a periodic cylinder of length L = 2 π R , driven by helical electrodes. The drive is single helicity, depending on m θ + k z = m θ - n ζ , where ζ = z / R and k = - n / R . For strong ( m , n ) = ( 1 , 1 ) drive, the state was found to have a strong axial mean current density, with a mean-field safety factor q 0 ( r ) just above the pitch of the electrodes m / n = 1 in the interior. This state has possible applications to DC electrical transformers and tailoring of the current profile in tokamaks. We study two geometric issues of interest for these applications: (i) scaling of properties with the plasma length or aspect ratio and (ii) behavior for different helicities, specifically ( m , n ) = ( 1 , n ) for n > 1 and ( m , n ) = ( 2 , 1 ) .

    This article discusses the design and delivery of two international family therapy-focused mental health and psychosocial support training projects, one in a fragile state and one in a post-conflict state. The training projects took place in Southeast Asia and the Middle East/North Africa. Each was funded, supported, and implemented by local, regional, and international stakeholders, and delivered as part of a broader humanitarian agenda to develop human resource capacity to work with families affected by atrocities. The two examples illustrate how task-shifting/task-sharing and transitional justice approaches were used to inform the scaling-up of professionals involved in each project. They also exemplify how state-citizen phenomena in each location affected the project design and delivery. © 2014 Family Process Institute.

  8. Steady state and a general scale law of deformation

    Steady state deformation has been characterized based on the experimental results for dilute single-phase aluminium alloys. It was found that although characteristic properties such as flow stress and grain size remained constant with time, a continuous loss of grain boundaries occurred as an essential feature at steady state. A physical model, which takes into account the activity of grain boundary dislocations, was developed to describe the kinetics of steady state deformation. According to this model, the steady state as a function of strain rate and temperature defines the limit of the conventional grain size and strength relationship, i.e., the Hall-Petch relation holds when the grain size is larger than that at the steady state, and an inverse Hall-Petch relation takes over if grain size is smaller than the steady state value. The transition between the two relationships relating grain size and strength is a phenomenon that depends on deformation conditions, rather than an intrinsic property as generally perceived. A general scale law of deformation is established accordingly.

  9. Researching state shame with the Experiential Shame Scale.

    2014-01-01

    Although debilitating effects of experiencing shame are posited in several theories of emotion and motivation, little research has been conducted on individuals' "in-the-moment" feelings of shame (i.e., state shame). However, researching state shame is challenging because individuals may deny or underreport their feelings of shame, tend to self-isolate when they feel shame, and may be unwilling or unable to express themselves when feeling shame. The Experiential Shame Scale (ESS), an "opaque" measure of physical, emotional, and social markers of shame experiences, was developed to address the difficulties of assessing state shame. Evidence obtained in three studies of individuals' emotional reactions following personally important exam feedback suggests that students' ESS ratings were uniquely related to feelings of state shame and not to state guilt. Findings also reveal that state shame is specifically related to feelings of shock and not surprise. As intended, findings suggested that the ESS has low face validity and is not related to social desirability.

  10. Neural Basis of Psychological Growth following Adverse Experiences: A Resting-State Functional MRI Study.

    Takashi X Fujisawa

    Full Text Available Over the past decade, research on the aftereffects of stressful or traumatic events has emphasized the negative outcomes from these experiences. However, the positive outcomes deriving from adversity are increasingly being examined, and such positive changes are described as posttraumatic growth (PTG. To investigate the relationship between basal whole-brain functional connectivity and PTG, we employed resting-state functional magnetic resonance imaging and analyzed the neural networks using independent component analysis in a sample of 33 healthy controls. Correlations were calculated between the network connectivity strength and the Posttraumatic Growth Inventory (PTGI score. There were positive associations between the PTGI scores and brain activation in the rostral prefrontal cortex and superior parietal lobule (SPL within the left central executive network (CEN (respectively, r = 0.41, p < 0.001; r = 0.49, p < 0.001. Individuals with higher psychological growth following adverse experiences had stronger activation in prospective or working memory areas within the executive function network than did individuals with lower psychological growth (r = 0.40, p < 0.001. Moreover, we found that individuals with higher PTG demonstrated stronger connectivity between the SPL and supramarginal gyrus (SMG. The SMG is one of the brain regions associated with the ability to reason about the mental states of others, otherwise known as mentalizing. These findings suggest that individuals with higher psychological growth may have stronger functional connectivity between memory functions within the CEN and social functioning in the SMG, and that their better sociality may result from using more memory for mentalizing during their daily social interactions.

  11. The professionalization of psychology within the apartheid state 1948-1978.

    When the National Party came to power in South Africa in 1948 it inherited an ageing colonial psychiatric system underpinned by British-based mental health legislation promulgated in 1916. This situation remained substantially unchanged until the late 1960s, despite the apartheid government's far-reaching attempts to restructure other aspects of the social landscape. The 1966 assassination of South Africa's prime minister by a schizophrenic parliamentary messenger led directly to a series of commissions of enquiry into the management of mental health services, followed by new mental health legislation in 1973 and the compulsory registration of clinical psychologists. The increasing professionalization of psychology, and the apartheid state's policy in relation to the profession, are considered in the light of local and international influences. Unlike the Nazi and Soviet governments, the apartheid state did not seek to create a new psychology and psychiatry in its own image but was instead motivated by a desire to emulate Western models and to identify and control the dangerous individual.

    1994-09-01

    Twenty-one male amateur athletes attending a Welsh needle-exchange clinic, were asked to complete the Buss-Durke Inventory on feelings of hostility/aggression, and a feeling state questionnaire. All were weight training in local gyms in order to increase their body mass. They were also using high doses of anabolic steroids during 6-14 week cycles, while between these cycles they were steroid free. Subjects reported significantly higher feelings of aggression, aggression towards objects, verbal aggression, and aggression during training (but not physical aggression towards people), during the on-steroid periods. Other changes on-drug, included significantly higher feelings of alertness, irritability, anxiety, suspiciousness, and negativism. While increased aggressiveness has been noted in many previous studies, the present findings demonstrate that anabolic steroids can affect a wide range of psychological mood states.

    Govia, Ishtar O.

    The mental health of ethnic minorities in the United States is of urgent concern. The accelerated growth of groups of ethnic minorities and immigrants in the United States and the stressors to which they are exposed, implores academic researchers to investigate more deeply health disparities and the factors that exacerbate or minimize such inequalities. This dissertation attended to that concern. It used data from the National Survey of American Life (NSAL), the first survey with a national representative sample of Black Caribbeans, to explore mechanisms that involved in the psychological distress of Black Caribbeans in the United States. In a series of three studies, the dissertation investigated the role and consequence of (1) chronic discrimination, immigration factors, and closeness to ethnic and racial groups; (2) personal control and social support; and (3) family relations and social roles in the psychological distress of Black Caribbeans. Study 1 examined how the associations between discrimination and psychological distress were buffered or exacerbated by closeness to ethnic group and closeness to racial group. It also examined how these associations differed depending on immigration factors. Results indicated that the buffering or exacerbating effect of ethnic and racial group closeness varied according to the type of discrimination (subtle or severe) and were more pronounced among those born in the United States. Using the stress process framework, Study 2 tested moderation and mediation models of the effects of social support and personal control in the association between discrimination and distress. Results from a series of analyses on 579 respondents suggested that personal control served as a mediator in this relationship and that emotional support exerted a direct distress deterring function. Study 3 investigated sex differences in the associations between social roles, intergenerational family relationship perceptions and distress. Results

    The Psychological Sense of School Membership Scale (PSSM) is a widely used instrument to assess the sense of belonging to a school among adolescents. Despite its widespread use in middle and high school students, to date no particular adaptation study has been conducted for its use among university students. For this reason, the present study conducted an adaptation of the PSSM scale for these students. Five hundred and nine students at a Turkish university voluntarily participated in the study, and the PSSM Scale's factor structure was examined by exploratory and confirmatory factor analyses, identifying three factors representing the students' sense of university membership with acceptable internal consistencies: acceptance by faculty members (.70), belonging (.75), and acceptance by students (.76). The internal consistency of the 18-item scale was calculated as .84. As hypothesized, the convergent and discriminant validity of the scale was also tested. The self-report sense of belonging and degree of satisfaction with the university were positively correlated with the three dimensions of the scale. Also, the scores regarding the students' intention to drop out of university along with loneliness were negatively correlated with all the dimension of the PSSM scale.

    To develop a suitable fat intake behavior of psychological measurement scales for the Chinese adolescents and evaluate its validity and reliability. According to the multi-stage stratified cluster sampling principle, a total of 3 600 junior students were recruited from the classes in 12 selected high schools in Hangzhou, Wuhan and Xi'an from March to May, 2012. Based on introducing and translating the original scale abroad, Chinese version of adolescent fat intake behavior of psychological measurement scales was utilized in field investigations. The reliability was assessed, using Cronbach's α and split-half reliability; while exploratory factor analysis used to test its validity, with entries-dimension correlation coefficient (IIC), correlation coefficient between the scores and the dimension, and the dimension of correlation coefficient test content validity. The valid subject of the study was 3 448(of whom males were 52.4% (1 806/3 448) and female were 47.6% (1 642/3 448)), while the mean age was (14.85 ± 1.46) years old. The internal consistency reliability (Cronbach's α) for total scale score and four domains were 0.922,0.933, 0.660, 0.773 and 0.869 respectively, whose split-efficacy reliability were separately 0.927, 0.933, 0.790, 0.624 and 0.889. Data from the exploratory factor analysis revealed the following dimensions:the entries were all inclusive, with the cumulative contribution rate at 59.453%, 56.062% and 52.668%, respectively. The results of IIC showed that in the four dimensions, the contained entries between Spearman correlation coefficient have statistically significant, with the r value range of 0.584-0.793, 0.665-0.818, 0.654-0.765 and 0.622-0.747 severely, while other dimensions from weak to moderate relationships, the r value ranged from -0.028 to 0.614. The reliability and validity of the adolescent fat intake behavior of psychological measurement scales (Chinese version) were good, and could be used to measure the fat intake behavior of

    Open quantum dots provide a window into the connection between quantum and classical physics, particularly through the decoherence theory, in which an important set of quantum states are not 'ashed out' through interaction with the environment-the pointer states provide connection to trapped classical orbits which remain stable in the dots. Graphene is a recently discovered material with highly unusual properties. This single layer, one atom thick, sheet of carbon has a unique bandstructure, governed by the Dirac equation, in which charge carriers imitate relativistic particles with zero rest mass. Here, an atomic orbital-based recursive Green's function method is used for studying the quantum transport. We study quantum fluctuations in graphene and bilayer graphene quantum dots with this recursive Green's function method. Finally, we examine the scaling of the domiant fluctuation frequency with dot size.

    2008-10-01

    There is much debate over when it is appropriate to intervene medically for psychological distress, and limited evidence on patients' perspectives about a broad range of possible treatment options. It is currently unclear whether preferences may differ for those patients with milder symptoms compared to those experiencing more severe distress. To determine patient preferences for professional, informal, and alternative help for psychological distress in primary care, and the impact of their current mental state on these. Cross-sectional survey in seven general practices across suburban/urban London. Participants were 1357 consecutive general practice attenders aged 18 years and over. The main outcome measure was the General Health Questionnaire 12-item version and a questionnaire on help-seeking preferences. Overall, only 47% of participants reported wanting 'some help' if feeling stressed, worried, or low and it was affecting their daily life. Those currently experiencing mild-to-moderate distress preferred informal sources of help such as friends/family support, relaxation/yoga, exercise/sport, or massage along with general advice from their GP and talking therapies. Self-help (books/leaflets or computer/internet) was not popular at any level of distress, and less favoured by those with mild-to-moderate distress (odds ratio [OR] = 0.50; 95% confidence interval [CI] = 0.35 to 0.70). Those experiencing severe distress were much more likely to want talking therapies (OR = 3.43, 95% CI = 2.85 to 4.14), tablets (OR = 3.07, 95% CI = 2.00 to 4.71), and support groups (OR = 3.07, 95% CI = 1.72 to 5.47). People with mild-to-moderate distress appear to prefer informal sources of help and those involving human contact, compared to medication or self-help. This has implications for the implementation of potential interventions for psychological distress in primary care.

    2002-01-01

    This survey assessed how early speech rehabilitation influences the emotional state and psychological adjustment of 43 male laryngectomy patients, at three different chronological stages. The first assessment occurred 2-3 days before the operation. The patients filled out a stress questionnaire (SVF) which assessed coping strategies. Exactly 2 weeks after the operation the patients were given a list of adjectives (EWL) which measured their actual emotional state. One day before leaving the hospital the patients were given the Post-laryngectomy Telephone Test (PLTT) which ascertained the quality of speech intelligibility. In addition, patients filled out a questionnaire on postoperative stress and anticipated stigmatisation with regard to their changed voice. Results demonstrated that patients who had early speech rehabilitation felt significantly more active and, in general, felt considerably better than patients who had not received speech rehabilitation training. Patients assessed voice loss as extremely distressing. The postoperative stress and the anticipated stigmatisation on the basis of the changed voice was significantly higher in those patients with good speech intelligibility than in patients with poor speech articulation at hospital discharge. The coping strategies "Giving up and resignation" and "Need for social support" correlated positively with postoperative stress and anticipated stigmatisation. Results show that early speech rehabilitation with voice prostheses had a positive effect on the emotional state of laryngectomy patients. However, the early speech rehabilitation leads to distress in the initial phase in laryngectomy patients. Moreover, patients who habitually tend towards resignation, or need lots of social support should receive psychological support during the early phase of speech rehabilitation training.

    A major barrier to the widespread dissemination of psychological treatments is the way that therapists are trained. The current method is not scalable. Our objective was to conduct a proof-of-concept study of Web-centered training, a scalable online method for training therapists. The Irish Health Service Executive identified mental health professionals across the country whom it wanted to be trained in a specific psychological treatment for eating disorders. These therapists were given access to a Web-centered training program in transdiagnostic cognitive behavior therapy for eating disorders. The training was accompanied by a scalable form of support consisting of brief encouraging telephone calls from a nonspecialist. The trainee therapists completed a validated measure of therapist competence before and after the training. Of 102 therapists who embarked upon the training program, 86 (84.3%) completed it. There was a substantial increase in their competence scores following the training (mean difference 5.84, 95% Cl -6.62 to -5.05; P<.001) with 42.5% (34/80) scoring above a predetermined cut-point indicative of a good level of competence. Web-centered training proved feasible and acceptable and resulted in a marked increase in therapist competence scores. If these findings are replicated, Web-centered training would provide a means of simultaneously training large numbers of geographically dispersed trainees at low cost, thereby overcoming a major obstacle to the widespread dissemination of psychological treatments.

    Emerging evidence indicates that individuals reporting more positive affect are healthier and live longer. The aim of this study was to examine if positive states of mind moderates the effect of perceived stress on psychological functioning and perceived health. A cross-sectional sample, n = 382, responded to questions regarding perceived stress, depression, anxiety, perceived health, and frequency of positive states of mind. Using a series of regression analyses, the results confirmed a moderating role of positive states of mind on the association between perceived stress and psychological outcomes. Among people experiencing a high frequency of positive states of mind, perceived stress seems to have a low correspondence with depression, anxiety, and perceived health. But among those reporting a low frequency of positive states of mind, perceived stress was more strongly related and depression, anxiety, and perceived health suggesting a buffering effect of positive states of mind against the negative influence of stress.

    The results of the socio-psychological and psycho-physiological study of children and adolescents rural secondary school in a remote area of the Arkhangelsk region were studied. It was found that the poor situation of children in families at social risk leads to a decrease in their school performance, motivation to succeed and, in some cases, to reduce their personal social and psychological adaptation. However, in general, the level of personal social and psychological adaptation in the majority of surveyed students is high enough. As complementary social institutions, the family and the school, in some cases, can compensate for a number of adverse social and psychological factors. Pupils from social risk groups functional state of the central nervous system has been significantly reduced compared with children who are brought up in affluent families. In the North adverse social factors may increase the effects of the harsh climatic conditions and are an important risk factor for children's health.

    State licensing boards have obligations to protect the public from impaired professionals and to protect the rights of professionals applying for licensure. Competently functioning professionals who have or have had a mental health diagnosis or are being treated for a mental health condition should not be screened out, according to the Americans with Disabilities Act (ADA). A review of case law shows applicable precedents from discrimination among physicians and lawyers but not, to date, among psychologists. An examination of psychology licensure application materials from all 50 states and the District of Columbia revealed that some states, particularly Alaska, Arkansas, Colorado, Florida, Georgia, Kentucky, Missouri, Montana, and New Hampshire, include language that might screen out professionals with lived experience who are currently functioning competently. For comparison, we review a sample of licensure applications for physicians and lawyers and find a similar pattern. Five of the present authors offer ourselves and other published authors as examples of competent licensed psychologists who have lived with mental illnesses. We conclude with recommendations for more inclusive language and protection of confidentiality. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Resilience helps determine how people respond to stress. The Response to Stressful Events Scale (RSES) is an existing 22-item measure of resilience. We investigate the psychometric properties of the RSES and develop a 4-item measure of resilience using the most discriminating items from the RSES. Among two samples of military personnel presenting to mental health clinics, we see that the abbreviated resilience measure displays comparable internal consistency and test-retest reliability (versus the existing RSES). Among a sample of deployed military personnel, the abbreviated scale relates to validated measures of psychological strain. The 4-item abbreviated RSES measure is a brief, reliable, and valid measure of resilience. Reprint & Copyright © 2016 Association of Military Surgeons of the U.S.

    The aim of the present study was to develop and provide validation statistics for the Persian Injury-Psychological Readiness to Return to Sport scale (I-PRRS) following a cross-sectional and prospective cohort study design. The I-PRRS was forward/back-translated and culturally adapted into Persian language. The Persian I-PRRS was administered to 100 injured athletes (93 male; age 26.0 ± 5.6 years; time since injury 4.84 ± 6.4 months) and 50 healthy athletes (36 male; mean age 25.7 ± 6.0 years). The Persian I-PRRS was re-administered to 50 injured athletes at 1 week to examine test-retest reliability. There were no floor or ceiling effects confirming the content validity of Persian I-PRRS. The internal consistency reliability was good. Excellent test-retest reliability and agreement were demonstrated. The statistically significant difference in Persian I-PRRS total scores between the injured athletes and healthy athletes provides an evidence of discriminative validity. The Persian I-PRRS total scores were positively correlated with the Farsi Mood Scale (FARMS) total scores, showing construct validity. The principal component analysis indicated a two-factor solution consisting of "Confidence to play" and "Confidence in the injured body part and skill level". The Persian I-PRRS showed excellent reliability and validity and can be used to assess injured athletes' psychological readiness to return to sport among Persian-speaking populations.

    The group of filamentous fungi contains important species used in industrial biotechnology for acid, antibiotics and enzyme production. Their unique lifestyle turns these organisms into a valuable genetic reservoir of new natural products and biomass degrading enzymes that has not been used to full capacity. One of the major bottlenecks in the development of new strains into viable industrial hosts is the alteration of the metabolism towards optimal production. Genome-scale models promise a reduction in the time needed for metabolic engineering by predicting the most potent targets in silico before testing them in vivo. The increasing availability of high quality models and molecular biological tools for manipulating filamentous fungi renders the model-guided engineering of these fungal factories possible with comprehensive metabolic networks. A typical fungal model contains on average 1138 unique metabolic reactions and 1050 ORFs, making them a vast knowledge-base of fungal metabolism.

    Full Text Available The monitoring of patients, by themselves and their caregivers, is very important in the prophylaxis of bipolar disorder. This study aimed to develop a Chinese-language version of an instrument for assessment of manic and depressive symptoms by patients and their families. Fifty-eight inpatients and outpatients with a DSM-IV (Diagnostic and Statistical Manual of Mental Disorders diagnosis of bipolar disorder were recruited. All subjects underwent clinical psychopathologic assessment by experienced psychiatrists using the Young Mania Rating Scale (YMRS and the Hamilton Depression Rating Scale (HDRS. At the same time, each patient and key family members filled out the Chinese-language version of the Internal State Scale (ISS for monitoring mental symptoms. Patients were examined a second time if they had entered remission or a new episode of the opposite polarity. The ISS was divided into two subscales, of well-being/activation and of irritability. Patients' well-being/activation and irritability subscales were significantly correlated with YMRS scores and the well-being/activation subscale was also significantly correlated with the HDRS score. Family members' irritability subscales were significantly correlated with HDRS scores only. The reliability and constructive validity of the ISS was good in both patients with bipolar disorder and their families.

    Individuals with substance dependence commonly experience anhedonia. Theories of anhedonia distinguish between anticipatory and consummatory reward deficits, with the Temporal Experience of Pleasure Scale (TEPS) the first self-report scale to separately measure these two constructs. Several psychometric studies have analysed the trait version of the TEPS, but the state version of the TEPS has not been previously validated. We examined the psychometric properties of the state version of the TEPS in 121 individuals with opiate dependence (81% Australian-born), to confirm its 2-factor structure and examine the internal consistency, convergent and divergent validity, test-retest reliability, and performance as a state measure. Confirmation of the 2-factor solution required removal of two items and allowing correlation between residuals of three pairs of highly-similar items. The resulting consummatory and anticipatory scales correlated strongly with each other (r=.76), suggesting poor divergent validity between them. Nevertheless, the scale showed good internal consistency (Chronbach's α: anticipatory=.90; consummatory=.84; total=.92), convergent (TEPS total and Snaith-Hamilton Pleasure Scale r=-.76) and divergent validity (-.38psychological measures, and test-retest reliability. Changes in TEPS scores between baseline and 1-month follow-up correlated well with changes in scores on other state anhedonia and positive affect measures, suggesting that the TEPS state version functions well as a state measure. In opioid-dependent participants, the TEPS state version appeared to have good validity as a measure of state anhedonia. However, evidence for its ability to distinguish between consummatory and anticipatory anhedonia was weak. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Given the emerging body of literature demonstrating the validity of the interpersonal-psychological theory of suicide (IPTS), and the importance of increasing our understanding of the development of risk factors associated with suicidal behavior, it seems worthwhile both to expand IPTS research via Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) correlates and to expand the availability of methods by which to assess the constructs of the IPTS. The present study attempted to do so in a large adult outpatient mental health sample by (a) inspecting associations between the IPTS constructs and the substantive scales of the MMPI-2-RF and (b) exploring the utility of MMPI-2-RF scale-based algorithms of the IPTS constructs. Correlates between the IPTS constructs and the MMPI-2-RF scales scores largely followed a pattern consistent with theory-based predictions, and we provide preliminary evidence that the IPTS constructs can be reasonably approximated using theoretically based MMPI-2-RF substantive scales. Implications of these findings are discussed. © The Author(s) 2016.

    Full Text Available In 1972, the first major national study on body image was conducted under the auspices of Psychology Today. Body image was assessed with the Body Parts Satisfaction Scale, which examined the dissatisfaction people experienced with 24 aspects of their bodies. Despite the continued reliance on this scale and reference to the study, data on the factor structure of this measure in a sample of adults have never been published, and citations of the original scale have relied on an unpublished manuscript (Bohrnstedt, 1977. An exploratory factor analysis conducted on 2,013 adults revealed factors for men (Face, Sex Organ, Height, Lower Body, Mid Torso, Upper Torso, Height and women (Face, Sex Organ, Height, Lower Torso, Mid Torso, Extremities, Breast. The factors were weakly to moderately intercorrelated, suggesting the scale can be analyzed by items, by subscales, or by total score. People who reported more dissatisfaction with their body also tended to report lower self-esteem and less comfort interacting with members of the other sex. The analyses provide a useful comparison point for researchers looking to examine gender differences in dissatisfaction with specific aspects of the body, as well as the factor structures linking these items.

    The Millon Clinical Multiaxial Inventory (MCMI) has become an important and commonly used instrument to assess personality functioning. Several studies report significant changes on MCMI personality disorder scales after psychological treatment. The aim of the study was to investigate whether pre-post-treatment changes in 39-session psychodynamic group psychotherapy as measured with the MCMI reflect real personality change or primarily reflect symptomatic state changes. Pre-post-treatment design included 236 psychotherapy outpatients. Personality changes were measured on the MCMI-II and symptomatic state changes on the Symptom Check List 90-R (SCL-90-R). The MCMI Schizoid, Avoidant, Self-defeating, and severe personality disorder scales revealed substantial changes, which could be predicted from changes on SCL-90-R global symptomatology (GSI) and on the SCL-90-R Depression scale. The MCMI Dependent personality score was the only MCMI personality scale showing significant change when the SCL-90-R Depression change score was included as a covariate. Splitting patients into those with and without personality disorders did not change the results. Observed changes on MCMI-II personality disorder scales in short-term psychotherapy reflect change in symptomatic state. The MCMI-II Base Rate cut-off points probably include too many patients, justifying the introduction of new scoring procedures in the MCMI-III.

    Hammack, Phillip L; Windell, Eric P

    2011-08-01

    Psychological science has assumed an increasingly explicit role in public policies related to same-sex desire in the United States. In this article, we present a historical analysis of the relationship between policy discourse and scientific discourse on homosexuality produced within U.S. psychology over the 20th and early 21st centuries through the lens of three cases: Bowers v. Hardwick (1986), Lawrence v. Texas (2003), and Perry v. Schwarzenegger (2010). Our analysis suggests that, for the majority of its disciplinary history, psychology produced knowledge that supported a status quo of legal and cultural subordination for same-sex-attracted individuals. The discipline's shift in understanding of homosexuality, reflected in a 1975 policy statement of the American Psychological Association, reversed this relationship and opened up space for advocacy for social and political change regarding homosexuality. Our analysis of policy decisions rendered by the courts reveals the increasingly important role psychological science has assumed in challenging the legal subordination of same-sex-attracted individuals, though the basis upon which psychological science has sought to inform policy remains limited. We conclude with a critical discussion of the type of knowledge claims psychologists have traditionally used to advocate for gay and lesbian rights, suggesting the vitality of a narrative approach which can reveal the meaning individuals make of legal subordination and political exclusion.

    The incidence of stroke is high in China. The dysphagia caused by cerebral infarction (CI), seriously affects patients' life quality, and even endangers patients' lives. It is necessary to explore how to improve dysphagia caused by CI. To compare the effects of rehabilitation training on dysphagia and psychological state after CI between Shaker exercise and chin tuck against resistance (CTAR) exercise. Control study. Blind. Inpatients. A total of 90 patients with dysphagia after CI were divided into CTAR group, Shaker group and control group by random digit table (each group with 30 patients). Video fluoroscopic swallowing study (VFSS) and Self-Rating Depression Scale (SDS) were performed on all patients before intervention. VFSS was evaluated based on Penetration-Aspiration Scale. All patients received routine treatments including internal medicine, traditional rehabilitation training and routine nursing. The patients in control group only receive the routine treatments. Besides the routine treatments, the patients in CTAR group also received CTAR exercise, and the patients in Shaker group also received Shaker exercise. VFSS was performed again on all patients, respectively, 2, 4, and 6 weeks after exercise. SDS was performed again on all patients 6 weeks after exercise. There were no statistical differences amongst the three groups in VFSS and SDS before intervention (P>0.05). After intervention, all patients had various degrees of improvement for dysphagia in the three groups, especially between 2 and 4 weeks in CTAR and Shaker groups. The total effective rate was significantly higher in CTAR group (86.67%) and Shaker group (76.67%) than in control group (43.33%) (all PShaker group and control group 6 weeks after intervention (all PShaker group. This study suggests that in conscious patients CTAR exercises have greater impact on CI-related depression than Shaker exercises.

    There is a lack of acceptable, reliable, and valid survey instruments to measure conceptual research utilization (CRU). In this study, we investigated the psychometric properties of a newly developed scale (the CRU Scale). We used the Standards for Educational and Psychological Testing as a validation framework to assess four sources of validity evidence: content, response processes, internal structure, and relations to other variables. A panel of nine international research utilization experts performed a formal content validity assessment. To determine response process validity, we conducted a series of one-on-one scale administration sessions with 10 healthcare aides. Internal structure and relations to other variables validity was examined using CRU Scale response data from a sample of 707 healthcare aides working in 30 urban Canadian nursing homes. Principal components analysis and confirmatory factor analyses were conducted to determine internal structure. Relations to other variables were examined using: (1) bivariate correlations; (2) change in mean values of CRU with increasing levels of other kinds of research utilization; and (3) multivariate linear regression. Content validity index scores for the five items ranged from 0.55 to 1.00. The principal components analysis predicted a 5-item 1-factor model. This was inconsistent with the findings from the confirmatory factor analysis, which showed best fit for a 4-item 1-factor model. Bivariate associations between CRU and other kinds of research utilization were statistically significant (p < 0.01) for the latent CRU scale score and all five CRU items. The CRU scale score was also shown to be significant predictor of overall research utilization in multivariate linear regression. The CRU scale showed acceptable initial psychometric properties with respect to responses from healthcare aides in nursing homes. Based on our validity, reliability, and acceptability analyses, we recommend using a reduced (four

    2002-01-01

    The quest for a psychological theory to explain the effects of aesthetic surgery reached its high point in the 1920s with the adoption of Alfred Adler's theory of the inferiority complex. The basis for this theory was Adler's early work in the psychological response of the body to disease and "degeneration". Aesthetic surgeons sought out the Adlerian model rather than a Freudian one as purely psychological while its roots, and their own theories, were clearly somatic in origin.

  3. Recent psychological explanations of infant development and scales of early mental development

    Maja Zupančič

    2002-12-01

    Full Text Available This paper reviews early infant measures based on standardised scales of development – both traditional ones and those based on Piaget's sensory-motor theory – and assesses their validity in predicting later mental development. The extremely low predictive power of test scores based on these measures in infancy has provided additional support for discontinuity theories of mental development from infancy to childhood. Conversely, the constructs implicit in earlier measures have been thoroughly criticised, and the search for valid measures of infant development that would reflect a construct similar to mental abilities in childhood has begun. At the outset, research was mostly influenced by the information processing theory. Two broad measures of information processing have been shown to be the most relevant indicators of an infant's mental development, namely habituation and dishabituation. Recent mental scales, such as the Bayley Scales of Infant Development-II, thus include items that measure the efficiency of an infant's information processing. Examples of such items are presented and interpreted, as are items reflecting the development of object permanence, the only early sensory-motor measure that shows better predictive effectiveness when compared to traditional developmental test scores. Several newly-developed indicators of infants' mental development, which utilize other measures than those derived from the information-processing approach, are surveyed (understanding causal relations, joint attention behaviours, representation of number, and their possible application within the context of potential items for early mental scales is discussed. Finally, the Bayley Scales of Infant Development-II, currently one of the best measures of early development, and presently undergoing a standardisation procedure in Slovenia, is evaluated, with analyses of some items from the Mental scale presented within the text.

    In the context of intimate partner violence, psychological abuse (PA) has progressively gained scientific relevance. Even so, a greater effort is needed to define and evaluate psychological intimate partner abuse. A new exhaustive and operative taxonomy of PA strategies leads to the contribution of a new evaluation instrument. Participants were 101 women between 24 and 82 years old, who were abused by their partners and attended to in different municipal Catalan services, specialized in the topic. The analyses have shown the suitability of a 19-item instrument divided into two factors: (1) direct PA strategies and (2) indirect PA strategies. The former includes strategies that affect the emotional, cognitive and behavioral dimension of the victim. The latter includes items that measure the amount of control and domination over the victim’s context. This scale has adequate psychometric properties in terms of score reliability and the validity of the relationship with other women’s health variables. The EAPA-P, created based on a new definition and taxonomy of the forms of PA, is presented as a valid instrument to detect and measure intimate partner PA.

    Full Text Available Symptoms of anhedonia, or deficits in the ability to experience positive affect, are increasingly recognized as an outcome of traumatic stress. Herein we demonstrate a phenomenon of “negative affective interference”, specifically, negative affective responses to positive events, in association with childhood trauma history. Young adults (n=99 completed a Hedonic Deficit & Interference Scale (HDIS, a self-report measure developed for this study, as well as a modified version of the Fawcette-Clarke Pleasure Capacity Scale that assessed not only positive but also negative affective responses to positive events. The two assessment approaches demonstrated convergent validity and predicted concurrent individual differences in trait positive and negative affect, and extraversion and neuroticism. Histories of childhood emotional and sexual abuse were differentially associated with negative affective responses to positive events. Future research and clinical directions are discussed.For the abstract or full text in other languages, please see Supplementary files under Reading Tools online.

    Recently, scholars have emphasized the importance of examining how employees cope with psychological contract violation and how the coping process contributes to psychological contract violation resolution and post-violation psychological contracts. Recent work points to the important role of problem-focused coping. Yet, to date, problem-focused coping strategies have not been conceptualized on a continuum from constructive to destructive strategies. Consequently, potential differences in the use of specific types of problem-focused coping strategies and the role these different strategies play in the violation resolution process has not been explored. In this study, we stress the importance of focusing on different types of problem-focused coping strategies. We explore how employee upward dissent strategies, conceptualized as different forms of problem-focused coping, contribute to violation resolution and post-violation psychological contracts. Two sources of data were used. In-depth interviews with supervisors of a Dutch car lease company provided 23 case descriptions of employee-supervisor interactions after a psychological contract violation. Moreover, a database with descriptions of Dutch court sentences provided eight case descriptions of employee-organization interactions following a perceived violation. Based on these data sources, we explored the pattern of upward dissent strategies employees used over time following a perceived violation. We distinguished between functional (thriving and reactivation), dysfunctional (impairment and dissolution) and deserted psychological contract end states and explored whether different dissent patterns over time differentially contributed to the dissent outcome (i.e., psychological contract end state). The results of our study showed that the use of problem-focused coping is not as straightforward as suggested by the post-violation model. While the post-violation model suggests that problem-focused coping will most

    Full Text Available Recently, scholars have emphasized the importance of examining how employees cope with psychological contract violation and how the coping process contributes to psychological contract violation resolution and post-violation psychological contracts. Recent work points to the important role of problem-focused coping. Yet, to date, problem-focused coping strategies have not been conceptualized on a continuum from constructive to destructive strategies. Consequently, potential differences in the use of specific types of problem-focused coping strategies and the role these different strategies play in the violation resolution process has not been explored. In this study, we stress the importance of focusing on different types of problem-focused coping strategies. We explore how employee upward dissent strategies, conceptualized as different forms of problem-focused coping, contribute to violation resolution and post-violation psychological contracts.

    The process of the establishment of forensic psychology in Israel begins in the eighties; while at the past 6 years after the creation of the Department of Psychology, Law and Ethics--The International Center for Health, Law and Ethics at Haifa University, the field continues to grow rapidly. Today, the development of forensic psychology is reflected in the scientific practice at Haifa University as at others (academic courses for different graduate levels and research concerning professional and ethical issues); as well as in the practical professional development of professional organizations, practice standards and training programs. Now as a specialty, forensic psychology must continue to make an effort to enrich in science and in professional practice, its aid in the administration of justice by assisting legal decision-makers.

  1. Measuring volunteers for exciting psychology experiments with the Sensation-Seeking Scale.

    1989-01-01

    The sensation-seeking motive was first operationalized by Zuckerman, Kolin, Price, and Zoob (1964) with the development of the Sensation-Seeking Scale (SSS). One area of applied research in which the SSS has been used is the study of volunteering. In this area, evidence suggests that high-sensation seekers volunteer for exciting activities more often than low-sensation seekers, but not for unexciting activities. However, a problem with this research is that no empirical data has been obtained related to the subject's belief of the exciting nature of the activities. In this study, college students were given the most recent form of the SSS and were asked to volunteer for either or both of two studies. SSS scores were higher, p less than .05, for volunteers than for nonvolunteers for a study that subjects rated as exciting, but did not differ for a study that subjects rated as unexciting. This demonstrates that volunteers for exciting studies, but not volunteers for unexciting studies, tend to be higher sensation seekers than nonvolunteers.

    Individuals in the state of psychological suboptimal health keep increasing, only scales and questionnaires were used to diagnose in clinic under current conditions, and symptoms of high reliability and accuracy are destitute. Therefore, the noninvasive and precise laboratory diagnostic methods are needed. This study aimed to develop an objective method through screen potential biomarkers or a biomarker panel to facilitate the diagnosis in clinic using plasma metabolomics. Profiles were based on H-nuclear magnetic resonance ((1)H-NMR) metabolomics techniques combing with multivariate statistical analysis. Furthermore, methods of correlation analysis with Metaboanalyst 3.0 for selecting a biomarker panel, traditional Chinese medicine (TCM) drug intervention for validating the close relations between the biomarker panel and the state and the receiver operating characteristic curves (ROC curves) analysis for evaluation of clinical diagnosis ability were carried out. 9 endogenous metabolites containing trimethylamine oxide (TMAO), glutamine, N-acetyl-glycoproteins, citrate, tyrosine, phenylalanine, isoleucine, valine and glucose were identified and considered as potential biomarkers. Then a biomarker panel consisting of phenylalanine, glutamine, tyrosine, citrate, N-acetyl-glycoproteins and TMAO was selected, which exhibited the highest area under the curve (AUC = 0.971). This study provided critical insight into the pathological mechanism of psychological suboptimal health and would supply a novel and valuable diagnostic method.

    Process model of stress and coping guided psychometric assessment of two brief measures of psychological well-being: Parenting Morale Index (PMI); Family Impact of Childhood Disability (FICD) scale. Canadian mothers (N=195) of children with disability (CWD) completed PMI, FICD, and validation measures (Brief Family Assessment Measure [FAM], Personal Well-Being Index, Positive and Negative Affect Schedule, General Self-Efficacy Scale, Social Desirability Scale) via computer-assisted telephone interview. Of these, 154 completed additional validation measures (Center for Epidemiological Studies-Depression Scale, Parenting Stress Index, Family Hardiness Index, Brief FAM) 1 year later. Factor structures of PMI and FICD were supported; both demonstrated internal consistency, temporal stability, and convergent and discriminant validity. After 1 year, PMI and FICD jointly predicted depressive symptoms, parenting stress, family hardiness, and family adjustment. PMI and FICD can identify mothers of CWD at risk for poor psychological well-being to increase the specificity of supports.

    A widely used and accepted scale for assessing resilience is the Connor-Davidson Resilience Scale (CD-RISC). The aim of the present study was to establish the psychometric properties of the Kannada version of the scale and assess the relationship between resilience and psychological distress in a sample of adolescent girls living in low-income settings. Data was obtained from a sample of 606 adolescent girls studying in a college meant for women from a socio-economically disadvantaged setting. The CD- RISC (25 item) was used to assess resilience and Kessler Psychological Distress Scale (K10) was used to assess psychological distress. Exploratory factor analysis yielded four stable factors instead of the original five factors. Similar results have been obtained in other factor-analytic studies. A significant negative correlation was found between psychological distress and resilience. Our study shows that the CD-RISC is a valuable measure to assess resilience among adolescents in low-income settings. Copyright © 2017 Elsevier B.V. All rights reserved.

    [Purpose] Although some studies suggest the importance of getting adequate sleep for enhancing mood, there is not yet sufficient evidence on the relationship between sleep and mood states in athletes, especially for athletes with physical disability. The purpose of this study is to reveal relationships between sleep and psychological mood states in female wheelchair basketball players. [Subjects and Methods] Seventeen female wheelchair basketball players (30.9 ± 9.4 years old) on a Japanese national team participated. Sleep states were assessed with the Pittsburgh Sleep Quality Index (PSQI), and mood states with the Japanese version of the Profile of Mood States short form (POMS-SF). Spearman's rank correlations were computed. [Results] The mean PSQI score was 5.4 ± 2.6 points, and 9 athletes (52.9%) exceeded the cutoff point (5.5) for insomnia. Higher sleep efficiency (rS=0.58), fewer sleep disturbances (rS=-0.58), and lower total PSQI score (rS=-0.51) were significantly correlated with higher vigor. Lower likelihood of daytime dysfunction was also significantly correlated with lower tension (rS=0.50). [Conclusion] Vigor was the mood state most frequently correlated with sleep variables. Because vigor is a known key psychological factor in optimal performance, the findings are valuable for wheelchair basketball players.

    The aim of this paper was to study the toxicity of organophosphate (OP) pesticides in exposed farmers for electroencephalography, cognitive state, psychological disorders, clinical symptom, oxidative stress, acetylcholinesterase, and DNA damage. A comparative cross-sectional analysis was carried out in 40 horticulture farmers who were exposed to OPs in comparison to a control group containing 40 healthy subjects with the same age and sex and education level. Lipid peroxidation (LPO), superoxide dismutase (SOD), catalase, glutathione peroxidase, DNA damage, total antioxidant capacity (TAC), total thiol molecules, and acetylcholinesterase (AChE) activity were measured in the blood of subjects. Clinical examination and complete blood test were undertaken in order to record any abnormal sign or symptoms. Cognitive function, psychological symptoms, and psychological distress were examined and recorded. Comparing with controls, the farmers showed higher blood levels of SOD and LPO while their TAC decreased. Farmers showed clinical symptoms such as eczema, breathing muscle weakness, nausea, and saliva secretion. Regarding cognitive function, the orientation, registration, attention and calculation, recall, and language were not significantly different in farmers and controls. Among examinations for psychological distress, only labeled somatization was significantly higher in farmers. The present findings indicate that oxidative stress and inhibition of AChE can be seen in chronically OP-exposed people but incidence of neuropsychological disorders seems a complex multivariate phenomenon that might be seen in long-term high-dose exposure situations. Use of supplementary antioxidants would be useful in the treatment of farmers.

    Full Text Available Orientation: Given the interest in the impact of positive psychology on employees, it is imperative to use reliable and valid instruments to operationalise positive-psychology constructs. One such construct is hope.Research purpose: The purpose of the study was to assess the degree of factorial invariance across race and gender by using a sample of aspiring chartered accountants.Motivation for the study: Previous research on the hope construct and associated measuring instruments have been conducted, using homogenous samples from Westernised cultures. Researchers need to be careful to assume that hope looks and behaves in exactly the same manner across cultures and groups.Research approach, design and method: A cross-sectional quantitative research design was used. A sample of 295 aspiring chartered accountants participated in the study. Exploratory factor analysis was used to determine the degree of factor similarity across groups, utilising Tucker’s coefficient of congruence. To supplement the exploratory factor analysis, a series of increasingly restrictive multi-group analyses were conducted to test the invariance of model parameters across the groups.Main findings: No significant differences were found in the factor patterns for the agency and pathways factors for (1 the white and designated groups and (2 females and males.Practical/managerial implications: Evidence related to factorial invariance was found. This should inform researchers and practitioners that both pathways and agency look similar across racial and gender groups.Contribution/value-add: Researchers are urged to use various statistical techniques, in combination, to determine the degree of factorial invariance across groups.

    Full Text Available Objective. The current study is aimed at investigating the association between stressful life events and psychological problems in a large sample of Iranian adults. Method. In a cross-sectional large-scale community-based study, 4763 Iranian adults, living in Isfahan, Iran, were investigated. Grouped outcomes latent factor regression on latent predictors was used for modeling the association of psychological problems (depression, anxiety, and psychological distress, measured by Hospital Anxiety and Depression Scale (HADS and General Health Questionnaire (GHQ-12, as the grouped outcomes, and stressful life events, measured by a self-administered stressful life events (SLEs questionnaire, as the latent predictors. Results. The results showed that the personal stressors domain has significant positive association with psychological distress (β=0.19, anxiety (β=0.25, depression (β=0.15, and their collective profile score (β=0.20, with greater associations in females (β=0.28 than in males (β=0.13 (all P<0.001. In addition, in the adjusted models, the regression coefficients for the association of social stressors domain and psychological problems profile score were 0.37, 0.35, and 0.46 in total sample, males, and females, respectively (P<0.001. Conclusion. Results of our study indicated that different stressors, particularly those socioeconomic related, have an effective impact on psychological problems. It is important to consider the social and cultural background of a population for managing the stressors as an effective approach for preventing and reducing the destructive burden of psychological problems.

    Full Text Available Knowledge discovery from data is an interdisciplinary research field combining technology and knowledge from domains of statistics, databases, machine learning and artificial intelligence. Data mining is the most important part of knowledge discovery process. The objective of this paper is twofold. The first objective is to point out the qualitative shift in research methodology due to evolving knowledge discovery technology. The second objective is to introduce the technique of decision trees to psychological domain experts. We illustrate the utility of the decision trees on the prediction model of sensation seeking. Prediction of the Zuckerman's Sensation Seeking Scale (SSS-V score was based on the bundle of Eysenck's personality traits and Pavlovian temperament properties. Predictors were operationalized on the basis of Eysenck Personality Questionnaire (EPQ and Slovenian adaptation of the Pavlovian Temperament Survey (SVTP. The standard statistical technique of multiple regression was used as a baseline method to evaluate the decision trees methodology. The multiple regression model was the most accurate model in terms of predictive accuracy. However, the decision trees could serve as a powerful general method for initial exploratory data analysis, data visualization and knowledge discovery.

    We present a parameter-free scheme to combine fixed-order multi-jet results with parton-shower evolution. The scheme produces jet cross sections with leading-order accuracy in the complete phase space of multiple emissions, resumming large logarithms when appropriate, while not arbitrarily enforcing ordering on momentum configurations beyond the reach of the parton-shower evolution equation. This requires the development of a matrix-element correction scheme for complex phase-spaces including ordering conditions as well as a systematic scale-setting procedure for unordered phase-space points. The resulting algorithm does not require a merging-scale parameter. We implement the new method in the Vincia framework and compare to LHC data. (orig.)

    Previous research examined "general instability" and "psychopathy" scales, derived from the 16PF, in terms of Foulds' criteria of content, group differentiation, change over time, and score distributions. When the external criterion of a newly validated measure of psychiatric mood state (the DSSI/sAD) was used, it was confirmed in both a patient and a normal group that the "general instability" scale is related significantly to symptomatology, while the "psychopathy" scale is relatively independent of present state.

    We introduce The Psychological Adaptation Scale (PAS) for assessing adaptation to a chronic condition or risk and present validity data from six studies of genetic conditions. Informed by theory, we identified four domains of adaptation: effective coping, self-esteem, social integration, and spiritual/existential meaning. Items were selected from the PROMIS "positive illness impact" item bank and adapted from the Rosenberg self-esteem scale to create a 20-item scale. Each domain included five items, with four sub-scale scores. Data from studies of six populations: adults affected with or at risk for genetic conditions (N=3) and caregivers of children with genetic conditions (N=3) were analyzed using confirmatory factor analyses (CFA). CFA suggested that all but five posited items converge on the domains as designed. Invariance of the PAS amongst the studies further suggested it is a valid and reliable tool to facilitate comparisons of adaptation across conditions. Use of the PAS will standardize assessments of adaptation and foster understanding of the relationships among related health outcomes, such as quality of life and psychological well-being. Clinical interventions can be designed based on PAS data to enhance dimensions of psychological adaptation to a chronic health condition or risk. Published by Elsevier Ireland Ltd.

    The Mindful Attention Awareness Scale (MAAS) measures perceived degree of inattentiveness in different contexts and is often used as a reversed indicator of mindfulness. MAAS is hypothesized to reflect a psychological trait or disposition when used outside attentional training contexts, but the long-term test-retest reliability of MAAS scores is virtually untested. It is unknown whether MAAS predicts psychological health after controlling for standardized socioeconomic status classifications. First, MAAS translated to Danish was validated psychometrically within a randomly invited healthy adult community sample (N = 490). Factor analysis confirmed that MAAS scores quantified a unifactorial construct of excellent composite reliability and consistent convergent validity. Structural equation modeling revealed that MAAS scores contributed independently to predicting psychological distress and mental health, after controlling for age, gender, income, socioeconomic occupational class, stressful life events, and social desirability (β = 0.32-.42, ps psychological distress (z = 2.78, p = .005). Test-retest reliability estimates did not differ within demographic and socioeconomic strata. Scores on the Danish MAAS were psychometrically validated in healthy adults. MAAS's inattentiveness scores reflected a unidimensional construct, long-term reliable disposition, and a factor of independent significance for predicting psychological health.

A process-oriented approach was used with nine women elite fencers during an international competition. Multiple assessments of perceived control, threat and challenge appraisals, problem- and emotion-focused coping, positive and negative affects were completed after each touches using video recall method. Multilevel growth curve analyses (MGCAs) indicated that winning and losing matches were each characterised by distinct psychological processes. Specifically, perceived control, challenge appraisal, problem- and emotion-focused coping, and positive affects increased linearly and threat appraisal decreased linearly for wining matches, whereas negative affects increased linearly for losing matches. Regarding the within-person synergies of psychological processes, MGCAs indicated that (1) perceived control and challenge appraisal were significantly associated with problem- and emotion-focused coping for losing matches, the strength of these associations remaining consistent across touches; (2) problem-focused coping was significantly associated with negative affects whereas emotion-focused coping was significantly associated with positive affects for winning matches, the strength of these associations remaining consistent across touches; and (3) problem- and emotion-focused coping were significantly associated with negative affects for losing matches, the linear trajectory of negative affects accelerating at times when athletes had higher levels of emotion-focused coping. Overall, this study provided insights into transactional processes during competition.

    Acute caffeine ingestion is considered effective in improving endurance capacity and psychological state. However, current knowledge is based on the findings of studies that have been conducted on male subjects mainly in temperate environmental conditions, but some physiological and psychological effects of caffeine differ between the sexes. The purpose of this study was to compare the physical performance and psychological effects of caffeine in young women and men exercising in the heat. Thirteen male and 10 female students completed 2 constant-load walks (60% of thermoneutral peak oxygen consumption on a treadmill until volitional exhaustion) in a hot-dry environment (air temperature, 42 °C; relative humidity, 20%) after caffeine (6 mg·kg -1 ) and placebo (wheat flour) ingestion in a double-blind, randomly assigned, crossover manner. Caffeine, compared with placebo, induced greater increases (p Caffeine decreased (p caffeine was associated with a shorter time to exhaustion. In conclusion, acute caffeine ingestion increases HR and blood lactate levels during exercise in the heat, but it has no impact on thermoregulation or endurance capacity in either gender. Under exercise-heat stress, caffeine reduces ratings of perceived exertion and fatigue in males but not in females.

    Teachers are an inseparable corner stone of the society and their satisfaction will affect the quality of service they render. Poor job satisfaction could result in job stress and this could affect their psychological health. This study aims to ascertain the level, causes of job dissatisfaction, intentions to quit and psychological morbidity among teachers in private secondary schools in a developing country. A cross-sectional study was conducted among teachers (392) in private secondary schools in Benin-City, Edo-State Nigeria, between June 2003 to November 2003. A total population of 400 teachers who had spent at least one year in the service were included in the study. The respondents completed a self-administered designed questionnaire and a standard instrument--The General Health Questionnaire (GHQ 28) The response rate was 98%. Fifty-eight (14.8%) of the respondents had psychological morbidity (GHQ score of 4 and above). One hundred and seventy-eight (45.4%) teachers were very satisfied or satisfied with their jobs. A significant number (45.9%) of teachers would want to quit their jobs. The proportion of teachers with GHQ score 4 and above increased with the level of dissatisfaction but this was not found to be statistically significant. Poor salary was found to be the main cause of job dissatisfaction and major reason for wanting to quit the job. This study shows a low level of job satisfaction among Nigerian teachers. Poor salary was the major cause of job dissatisfaction and intention to quit. Further work need to be done to ascertain the association of psychological morbidity and job dissatisfaction.

    In few-body physics, Efimov states are an infinite series of three-body bound states that obey universal discrete scaling symmetry when pairwise interactions are resonantly enhanced. Despite abundant reports of Efimov states in recent cold atom experiments, direct observation of the discrete scaling symmetry remains an elusive goal. Here we report the observation of three consecutive Efimov resonances in a heteronuclear Li-Cs mixture near a broad interspecies Feshbach resonance. The positions of the resonances closely follow a geometric series 1, λ, λ². The observed scaling constant λ(exp)=4.9(4) is in good agreement with the predicted value of 4.88.

    To investigate details of sexual function of erectile dysfunction in Japanese patients taking phosphodiesterase type 5 inhibitors. A Japanese version of the Psychological and Interpersonal Relationship Scales-Short Form was used to carry out a nationwide survey using the Internet. A total of 556 erectile dysfunction patients (age 30-70 years) who had been prescribed a phosphodiesterase type 5 inhibitor and had attempted sexual intercourse within the past 6 months were included in this survey. Scores were compared in relation to the phosphodiesterase type 5 inhibitors most frequently taken within the past 6 months. In the subdomains of self-confidence and spontaneity of the Psychological and Interpersonal Relationship Scales-Short Form, scores for vardenafil and tadalafil were significantly higher than those for sildenafil. In the subdomain of time concern of the Psychological and Interpersonal Relationship Scales-Short Form, the score for tadalafil was significantly lower than that for others. Our findings support the hypothesis that Japanese patients with erectile dysfunction have high sexual self-confidence, spontaneity and low time concerns when taking tadalafil. These characteristics of tadalafil could be associated with high patient satisfaction and high preference. © 2014 The Japanese Urological Association.

    Full Text Available Mindfulness-based interventions, rooted in old Buddhist practices, have been updated and adapted to the western context. In the present review, the most frequently used mindfulness interventions will be described as well as the psychological mechanisms activated by them. Afterwards, applied studies will be reviewed. First, clinical trials and meta-analytic studies focused on interventions for psychological disorders will be analyzed. Second, clinical trials and meta-analytic studies focused on interventions for health conditions will be analyzed. In the last section some important issues are addressed, such as, for instance, potential adverse effects, personality profiles that fit better with this type of interventions, and topics that need more attention, such as the analysis of efficacy compared with other well-validated interventions, are reviewed. The overall conclusion after the literature review is that mindfulness-based interventions show high versatility, being very suitable for primary health care or similar settings, and have demonstrated their best results in patients with symptoms of stress, anxiety, or depression.

    This paper presents a historical analysis of the genesis, context, and function of "Operative Psychology," a little-known branch of applied psychology developed by employees of the Ministry of State Security in the German Democratic Republic. For 25 years, theories and practices of Operative Psychology were taught to elite agents at the Juridical Academy in Potsdam, introducing them to various "silent" psychological techniques of persuasion, interrogation, and repression. After highlighting the economic and political context that increased the need for "silent" techniques of observation and repression, an overview of the topics that were taught and researched at the chair for Operative Psychology is given. Examples of how these techniques were put into practice are provided and the consequences for the victims of Operative Psychology are discussed. Furthermore, commonalities and differences between Operative Psychology and the use of psychological torture by the CIA during the "war on terror" are discussed and questions regarding the relation between methodological and moral strategies of justification are addressed. © 2017 Wiley Periodicals, Inc.

    In India, alcohol consumption per capita has increased in recent years, and child maltreatment is highly prevalent. We assess alcohol-related harms to children, including physical abuse, psychological abuse and neglect, and correlates for men reporting these harms. We analysed data from household interviews collected in a cross-sectional, case-control study in five Indian states (n = 5026). Data were collected from October 2011 to May 2012. Using multilevel mixed-effects logistic regression, we examined male adult's reports of five types of alcohol-related harm to children (respondents were not necessarily the perpetrators of the harms) and respondents' drinking patterns and socio-demographic characteristics associated with the reporting of these harms. In this sample, 43.2% of the men reported at least one alcohol-related harm to children in the past year; among them, 61.6% reported multiple. Among all men, 15.7% reported that a child experienced physical abuse from adults' drinking. Adjusting for respondents' drinking pattern and socio-demographics, multilevel mixed-effects logistic regression showed that living in a rural area was associated with greater odds of reporting alcohol-related physical abuse, psychological harm and neglect to children. Compared with past-year abstainers, both non-heavy episodic and heavy episodic drinkers had significantly greater odds of reporting these harms. We found significant differences in the reporting of harms by location. This study suggests that adults' drinking is associated with physical and psychological abuse and neglect to children. Greater use of evidence-based alcohol policy interventions may help reduce alcohol-related harms to children in India.

  1. Using the Daydreaming Frequency Scale to investigate the relationships between mind-wandering, psychological well-being, and present-moment awareness

    2012-09-01

    Full Text Available Recent findings have shown that mind-wandering—the occurrence of stimulus-independent and task-unrelated thoughts—is associated with negative affect and lower psychological well-being. However, it remains unclear whether this relationship is due to the occurrence of mind-wandering per se or to the fact that people who mind wander more tend to be generally less attentive to present-moment experience. In three studies, we first validate a French translation of a retrospective self-report questionnaire widely used to assess the general occurrence of mind-wandering in daily life―the Daydreaming Frequency Scale. Using this questionnaire, we then show that the relationship between mind-wandering frequency and psychological distress is fully accounted for by individual differences in dispositional mindful awareness and encoding style. These findings suggest that it may not be mind-wandering per se that is responsible for psychological distress, but rather the general tendency to be less aware and attentive to the present moment. Thus, although mind-wandering and present-moment awareness are related constructs, they are not reducible to one another, and are distinguishable in terms of their relationship with psychological well-being.

    To examine whether serious psychological distress (SPD), a nonspecific indicator of past year mental health problems, was associated with subsequent dental care utilization, dental expenditures, and unmet dental needs. We analyzed data from panel 13 thru 15 of the Medical Expenditure Panel Survey -Household Component (n=31,056). SPD was defined as a score of 13 or higher on the Kessler Psychological Distress Scale (K6). Logistic regression, zero-inflated negative binomial model, and generalized linear model (GLM) with a gamma distribution were used to test the study hypotheses. Adults with SPD had, in the subsequent year, 35 percent lower odds of adhering to annual dental checkups and a twofold increase in the odds of having unmet dental needs. Although adults with SPD did not have significantly more dental visits than those without SPD, they spent 20 percent more on dental care. SPD was a modest independent risk factor for lack of subsequent preventive dental care, greater unmet dental needs, and greater dental expenditures. In addition to expanding adult dental coverage, it is important to develop and evaluate interventions to increase the utilization of dental care particularly preventive dental services among people with mental illness in order to improve oral health and reduce dental expenditures among this vulnerable population. © 2014 American Association of Public Health Dentistry.

    The State-Trait Anxiety Inventory (STAI) and the Hamilton scale for anxiety (HARS) are two of the most important scales employed in clinical and psychological realms for the evaluation of anxiety. Although the reliability and sensibility of these scales are widely demonstrated there is an open debate on what exactly their scores reflect. Neuroimaging provides the potential to validate the quality and reliability of clinical scales through the identification of specific biomarkers. For this reason, we evaluated the neural correlates of these two scales in a large cohort of healthy individuals using structural neuroimaging methods. Neuroimaging analysis included thickness/volume estimation of cortical and subcortical limbic structures, which were regressed on anxiety inventory scores with age and gender used for assessing discriminant validity. A total of 121 healthy subjects were evaluated. Despite the two anxiety scales, at a behavioral level, displaying significant correlations among them (HARS with STAI-state (r = 0.24; P = 0.006) and HARS with STAI-trait (r = 0.42; P anxiety-like behaviors, our neuroimaging data indicated that these scales are neurobiologically different, confirming that their scores might reflect different aspects of anxiety: the HARS is more related to subclinical expression of anxiety disorders, whereas the STAI captures sub-dimensions of personality linked to anxiety.

    Full Text Available Brain damage of various aetiologies can lead to different disorders of consciousness (DOC, varying from coma to vegetative, to minimally conscious states. Each state is characterised by a different degree of wakefulness, awareness, pain sensitivity and is differentially handled with respect to treatment, ethical considerations and end-of-life decisions. Thus, its correct identification is crucial while devising or modulating appropriate treatment strategies. Actually, the main coma scales cannot always accurately determine the state of consciousness of an individual, while other tools (e.g. imaging techniques present a certain degree of uncertainty. A complementary approach may be constituted by a 24-hour observation of patients, for a sufficient period of days, using an ad hoc behavioural scale, further correlated with physiological and pharmacological parameters measured on patients. The method herein described might help recognising the presence of consciousness of the different DOC patients, and thus discerning a vegetative from a minimally conscious state.

    2013-08-07

    Magnolia (Magnolia officinalis) and Phellodendron (Phellodendron amurense) barks are medicinal plants commonly used as traditional remedies for reducing stress and anxiety. Modern dietary supplements are intended to induce relaxation and reduce stress as well as stress-related eating. Previous studies have shown the combination of Magnolia/Phellodendron (MP) to reduce both cortisol exposure and the perception of stress/anxiety, while improving weight loss in subjects with stress-related eating. Competitive athletes are "stressed" by their intense exercise regimens in addition to their normal activities of daily living and thus may benefit from a natural therapy intended to modulate baseline perceptions of stress and stress hormone exposure. We assessed salivary cortisol exposure and psychological mood state in 56 subjects (35 men and 21 women) screened for moderate stress and supplemented with a standardized/patented MP combination (Relora®, Next Pharmaceuticals) or Placebo for 4 weeks. After 4 weeks of supplementation, salivary cortisol exposure was significantly (pStress (-11%), Tension (-13%), Depression (-20%), Anger (-42%), Fatigue (-31%), and Confusion (-27%), and higher indices of Global Mood State (+11%) and Vigor (+18%). These results indicate that daily supplementation with a combination of Magnolia bark extract and Phellodendron bark extract (Relora®) reduces cortisol exposure and perceived daily stress, while improving a variety of mood state parameters, including lower fatigue and higher vigor. These results suggest an effective natural approach to modulating the detrimental health effects of chronic stress in moderately stressed adults. Future studies should examine the possible performance and recovery benefits of Relora supplementation in athletes overstressed by the physical and psychological demands of training and competition.

    We consider a general initial state for inflation as the mechanism for generating scale-dependent hemispherical asymmetry. An observable scale-dependent non-Gaussianity is generated that leads to observable hemispherical asymmetry from the super-horizon long mode modulation. We show that the amplitude of dipole asymmetry falls off exponentially on small angular scales which can address the absence of dipole asymmetry at these scales. In addition, depending on the nature of non-vaccum initial state, the amplitude of the dipole asymmetry has oscillatory features which can be detected in a careful CMB map analysis. Furthermore, we show that the non-vacuum initial state provides a natural mechanism for enhancing the super horizon long mode perturbation as required to generate the dipole asymmetry.

    A cross-sectional study with all the teachers in the municipal school system in Vitória da Conquista, Bahia State, Brazil, investigated the association between work content (psychological demand and control over work) and the occurrence of minor psychiatric disorders (MPD) among teachers. The Karasek demand-control model was used to evaluate control over work. The Self-Report Questionnaire-20 was used to evaluate minor psychiatric disorders. MPD prevalence was 55.9% among the 808 teachers studied. Crude prevalence of MPD showed a positive and significant association with psychological demand and a negative and significant association with control over work. MPD prevalence was higher in teachers with highly demanding work, characterized by heavy demand and low control (PR = 1.74; 95%CI: 1.44-2.10), and in those with active work, with heavy demand and low control (PR = 1.35; 95%CI: 1.13-1.61), as compared to teachers with low-demand work (light demand and high control), after adjusting for confounders in a multiple logistic regression model. As a conclusion, teachers' mental health is strongly associated with their work content.

    Full Text Available BACKGROUND: The Suicide Trigger Scale (STS was designed to measure the construct of an affective 'suicide trigger state.' This study aims to extend the inpatient setting validation study of the original Suicide Trigger Scale version 2 to the revised Suicide Trigger Scale version 3 (STS-3 in an acute psychiatric emergency room setting. METHODS: The 42-item STS-3 and a brief psychological test battery were administered to 183 adult psychiatric patients with suicidal ideation or attempt in the psychiatric emergency room, and re-administered to subjects at 1 year follow up. Factor analysis, linear and logistic regressions were used to examine construct structure, divergent and convergent validity, and construct validity, respectively. RESULTS: The STS-3 demonstrated strong internal consistency (Cronbach's alpha 0.94. Factor analysis yielded a three-factor solution, which explained 43.4% of the variance. Principal axis factor analysis was used to identify three reliable subscales: Frantic Hopelessness, Ruminative Flooding, and Near-Psychotic Somatization (Cronbach's alphas 0.90, 0.80, and 0.76, respectively. Significant positive associations were observed between Frantic Hopelessness and BSI depression and anxiety subscales, between Ruminative Flooding and BSI anxiety and paranoia subscales, and Near Psychotic Somatization and BSI somatization subscales. Suicidal subjects with suicide attempt history had mean scores 7 points higher than those without history of suicide attempts. Frantic hopelessness was a significant predictor of current suicide attempt when only attempts requiring at least some medical attention were considered. CONCLUSION: The STS-3 measures a distinct clinical entity, provisionally termed the 'suicide trigger state.' Scores on the STS-3 or select subscales appear to relate to degree of suicidality in terms of severity of ideation, history of attempt, and presence of substantive current attempts. Further study is required to

    © 2015 Macmillan Publishers Limited. Addressing climate change in the United States requires enactment of national, state and local mitigation and adaptation policies. The success of these initiatives depends on public opinion, policy support and behaviours at appropriate scales. Public opinion, however, is typically measured with national surveys that obscure geographic variability across regions, states and localities. Here we present independently validated high-resolution opinion estimate...

    Older people's emotional distress is often related to rumination processes focused on past vital events occurred during their lives. The specific coping strategies displayed to face those events may contribute to explain older adults' current well-being: they can perceive that they have obtained personal growth after those events and/or they can show a tendency to have intrusive thoughts about those events. This paper describes the development and analysis of the psychometric properties of the Scales for the Assessment of the Psychological Impact of Past Life Events (SAPIPLE): the past life events-occurrence scale (LE-O), ruminative thought scale (LE-R) and personal growth scale (LE-PG). Participants were 393 community dwelling elderly (mean age=71.5 years old; SD=6.9). In addition to the SAPIPLE scales, depressive symptomatology, anxiety, psychological well-being, life satisfaction, physical function and vitality have been assessed. The inter-rater agreement's analysis suggests the presence of two factors in the LE-O: positive and negative vital events. Confirmatory Factor Analysis (CFA) supported this two-dimensional structure for both the LE-R and the LE-PG. Good internal consistency indexes have been obtained for each scale and subscale, as well as good criterion and concurrent validity indexes. Both ruminative thoughts about past life events and personal growth following those events are related to older adults' current well-being. The SAPIPLE presents good psychometric properties that justify its use for elderly people. Copyright © 2012 SEGG. Published by Elsevier Espana. All rights reserved.

    Full Text Available Introduction. Nowadays, the problem of students’ adaptation to the educational process proves to be urgent, cardiovascular diseases ranking first among adaptation disorders. Early development of arterial hypertension (AH is of peculiar concern. However, the mechanisms of adaptation to the educational process as well as the causes accounting for the development of AH in young people have not been studied sufficiently so far. The objective is to find out the peculiarities of cardiac intervalography and psychological state of virtually healthy young males and females at different risk of AH development. Materials and methods. 150 boys and 173 girls aged 16 to 21 years, all of them were students of the medical university, were examined. Measurement of the arterial pressure (AP in the lying position was followed by the calculation of the mean hemodynamic pressure. The level above 90 mmHg pointed at high risk of AH development, whereas 90 mmHg and lower suggested its insignificant probability. Cardiac activity of autonomous regulation was estimated at the starting point and on the sixth minute of the postural test according to R.M.Baevsky method. The “BHC-Микро” device (Russia was used. Psychological characteristics were studied by FPI questionnaire (form B. Parametric methods of statistical analysis were used. The sampling contingent was formed by means of stratified randomization. Results. It was found that in the lying position the activity of the sympathetic part of the autonomic nervous system (ANS prevailed in boys and girls at high risk of AH development compared to those with the lower one. Adequate regulatory mechanisms were activated in orthostasis, specifically, the tone of the ANS sympathetic part increased. Students at low risk of AH development revealed enhanced intensity of regulatory mechanisms due to activation of both ANS parts. This appears to be adequate for the given group and indicates larger adaptation reserves, since

    Gingrich, Douglas M

    2015-01-01

    The possibility of producing non-perturbative low-scale gravity states in collider experiments was first discussed in about 1998. The ATLAS and CMS experiments have searched for non-perturbative low-scale gravity states using the Large Hadron Collider (LHC) with a proton--proton centre of mass energy of 8 TeV. These experiments have now seriously confronted the possibility of producing non-perturbative low-scale gravity states which were proposed over 17 years ago. I will summarise the results of the searches, give a personal view of what they mean, and make some predictions for 13 TeV centre of mass energy. I will also discuss early ATLAS 13 TeV centre of mass energy results.

    2017-09-01

    This study was to explore the relation between psychological strains and suicidal ideation among Chinese and American college students. Another secondary purpose of the study was to examine the reliability of the psychological strains scales (PPS: Ref) one more time in China and the United States in college populations. Samples of college students were randomly recruited from China and United States. All of 529 college students (aged 17-27, 68.9% female) completed self-report assessments of psychological strains (Psychological Strain Scale), suicidal ideation (Beck Scale for Suicide Ideation), and indicators of psychological well-being (e.g., depression, anxiety, and stress). Empirical results show that Psychological Strain Scales (PSS) has a good reliability. Chinese college students reported higher suicide ideation scores than American students whereas there was no statistical difference in psychological strains. Psychological strains and, depression, anxiety, and stress, were positively related to suicidal ideation in both countries. Stepwise multiple regression analysis indicated that psychological strain can significantly predict suicidal ideation. These findings provide support for the Strain Theory of Suicide for both Chinese and American college students and some measures can be taken to reduce psychological strains in students. However, future work could extend these findings by utilizing a longitudinal design to determine whether psychological strains are in fact antecedents, and not simply correlates, of suicide ideation.

    This report describes psychological assessments of the first time ritual use of ayahuasca in the religious groups União do Vegetal and Santo Daime. Nineteen subjects who tried the beverage in Santo Daime rituals and nine subjects who tried it in União do Vegetal rituals were evaluated one to four days before their first ayahuasca experience in life and one to two weeks after this experience. Semistructured interviews and a structured psychiatric scale were used in the first evaluation to elicit set variables concerning attitudes towards the ayahuasca experience and to elicit mental health status. Mental health status was reassessed in the second evaluation, which also included a semistructured interview concerning the phenomenology of altered states of consciousness (ASCs). Predominantly positive expectancies concerning the ayahuasca experience were the most prominent findings concerning set variables. Visual phenomena, numinousness, peacefulness, insights and a distressing reaction were the most salient ASC experiences. A significant reduction of the intensity of minor psychiatric symptoms occurred in the Santo Daime group after the hallucinogen experience. Subjects in both groups reported behavioral changes towards assertiveness, serenity and vivacity/joy. The set and setting hypothesis, suggestibility processes, as well as the supposed unique effects of ayahuasca are used in discussing these findings.

    Moor mud applications in the form of packs and baths are widely used therapeutically as part of balneotherapy. They are commonly given as therapy for musculoskeletal disorders, with their thermo-physical effects being furthest studied. Moor baths are one of the key therapeutic elements in our recently developed and evaluated 3-week prevention program for subjects with high stress level and increased risk of developing a burnout syndrome. An embedded pilot study add-on to this core project was carried out to assess the relaxing effect of a single moor bath. During the prevention program, 78 participants received a total of seven moor applications, each consisting of a moor bath (42 °C, 20 min, given between 02:30 and 05:20 p.m.) followed by resting period (20 min). Before and after the first moor application in week 1, and the penultimate moor application in week 3, salivary cortisol was collected, blood pressure and heart rate were measured, and mood state (Multidimensional Mood State Questionnaire) was assessed. A Friedman test of differences among repeated measures was conducted. Post hoc analyses were performed using the Wilcoxon signed-rank test. A significant decrease in salivary cortisol concentration was seen between pre- and post-moor bath in week 1 (Z = -3.355, p = 0.0008). A non-significant decrease was seen between pre- and post-moor bath in week 3. Mood state improved significantly after both moor baths. This pilot study has provided initial evidence on the stress-relieving effects of single moor baths, which can be a sensible and recommendable therapeutic element of multimodal stress-reducing prevention programs. The full potential of moor baths still needs to be validated. A randomized controlled trial should be conducted comparing this balneo-therapeutic approach against other types of stress reduction interventions.

    Full Text Available We apply simulated tempering and magnetizing (STM Monte Carlo simulations to the two-dimensional three-state Potts model in an external magnetic field in order to investigate the crossover scaling behaviour in the temperature-field plane at the Potts critical point and towards the Ising universality class for negative magnetic fields. Our data set has been generated by STM simulations of several square lattices with sizes up to 160x160 spins, supplemented by conventional canonical simulations of larger lattices at selected simulation points. We present careful scaling and finite-size scaling analyses of the crossover behaviour with respect to temperature, magnetic field and lattice size.

    This talk discusses the various applications of small scale quantum computers consisting of a few hundred qubits and capable of performing a few thousand quantum logic operations reliably without error corrections. Such small scale quantum computers could perform useful quantum simulations of many-body quantum systems, including processes of many body localization and scrambling. I will show that such small scale quantum computers could also be useful for quantum machine learning, revealing patterns in quantum states and in classical data that could not be revealed by even the most powerful classical supercomputer.

    Objective: The study aimed to explore and describe the extent and nature of reported potentially traumatic events and associated variables in adult patients referred for psychological services at the Free State Psychiatric Complex (FSPC, Bloemfontein. Methods: In this cross-sectional study, demographic information, diagnostic morbidity and co-morbidity, and presence and type of reported trauma exposure reported by patients during the initial assessment were obtained from files of adult patients seen during a one-year period (2010 at the out-patient unit and the in-patient affective ward at the FSPC. Data were captured on data record forms by the researchers and analysed by means of descriptive statistics, univariate analysis and logistic regression (SAS version 9.1. Results: Of the 192 adults (71.9% White and 67.2% female referred for psychological services,75.5% were diagnosed with mood disorders, 17.2% with anxiety disorders, 22.4% with substance-related disorders and 20.9% with cluster B personality disorders or traits. A total of 145 (75.5% reported past trauma exposure. The most frequently reported types of trauma exposure were traumatic death/injury of a loved one (37.0%, physical assault (24.5%, witnessed/threatened violence (19.3%, and sexual assault (17.7%. Women were more likely to have been exposed to trauma than men (OR 4.02, 95% CI 1.87–8.62, in particular to traumatic death of a loved one (OR 3.13, physical assault (OR 4.08, or sexual assault (OR 5.43. Conclusions: The findings of this study contribute to current data regarding the prevalence of exposure to trauma and its possible association with mental illness. The importance of comprehensive trauma exposure screening in routine psychiatric interviewing practices is highlighted.

    The Internal State Scale (ISS) was developed to simultaneously assess manic and depressive symptoms in bipolar disorder. In the present study, the validity and reliability of the Turkish version of ISS (ISS-TR) were examined. The present study aimed to present the psychometric properties of this scale. The sample consisted of 200 outpatients with bipolar disorder and 49 healthy controls. Participants completed the Turkish Internal State Scale (ISS-TR), the Brief Psychiatric Rating Scale (BPRS), the Hamilton Depression Rating Scale (HDRS), and the Young Mania Rating Scale (YMRS). Reliability analyses revealed that the Cronbach alfa coefficient of ISS was 0.88 for the whole sample. Item-total correlations ranged from 0.15 to 0.78. Two factors emerged as a result of factor analysis: "mania" and "depression-well-being." Test-retest correlations were determined for the mania subscale as r=0.654, preliable scale that can be used to simultaneously assess manic and depressive symptoms. It is thought that ISS will be useful in the recognition of prodromal symptoms and in the process of maintenance treatment.

  14. Validation of the Bipolar Disorder Etiology Scale Based on Psychological Behaviorism Theory and Factors Related to the Onset of Bipolar Disorder

    2014-01-01

    Objectives The aim of this study was to identify psychosocial factors related to the onset of bipolar I disorder (BD). To do so, the Bipolar Disorder Etiology Scale (BDES), based on psychological behaviorism, was developed and validated. Using the BDES, common factors related to both major depressive disorder (MDD) and BD and specific factors related only to BD were investigated. Method The BDES, which measures 17 factors based on psychological behaviorism hypotheses, was developed and validated. This scale was administered to 113 non-clinical control subjects, 30 subjects with MDD, and 32 people with BD. ANOVA and post hoc analyses were conducted. Subscales on which MDD and BD groups scored higher than controls were classified as common factors, while those on which the BD group scored higher than MDD and control groups were classified as specific factors. Results The BDES has acceptable reliability and validity. Twelve common factors influence both MDD and BD and one specific factor influences only BD. Common factors include the following: learning grandiose self-labeling, learning dangerous behavior, reinforcing impulsive behavior, exposure to irritability, punishment of negative emotional expression, lack of support, sleep problems, antidepressant problems, positive arousal to threat, lack of social skills, and pursuit of short-term pleasure. The specific factor is manic emotional response. Conclusions Manic emotional response was identified as a specific factor related to the onset of BD, while parents’ grandiose labeling is a candidate for a specific factor. Many factors are related to the onset of both MDD and BD. PMID:25549262

    M. Anushka S. Perera

    2015-07-01

    Full Text Available This paper discusses the topics related to automating parameter, disturbance and state estimation analysis of large-scale complex nonlinear dynamic systems using free programming tools. For large-scale complex systems, before implementing any state estimator, the system should be analyzed for structural observability and the structural observability analysis can be automated using Modelica and Python. As a result of structural observability analysis, the system may be decomposed into subsystems where some of them may be observable --- with respect to parameter, disturbances, and states --- while some may not. The state estimation process is carried out for those observable subsystems and the optimum number of additional measurements are prescribed for unobservable subsystems to make them observable. In this paper, an industrial case study is considered: the copper production process at Glencore Nikkelverk, Kristiansand, Norway. The copper production process is a large-scale complex system. It is shown how to implement various state estimators, in Python, to estimate parameters and disturbances, in addition to states, based on available measurements.

    No research group has ever investigated the level of kinesiophobia in a well defined group of preoperative patients treated due to cervical discopathy and degenerative spine disease, confirmed by X-ray and magnetic resonance imaging (MRI) examinations. We aimed to investigate the degree of kinesiophobia and the differences in pain-related and psychosocial characteristics between patients with high and low levels of kinesiophobia, in relation to factors commonly associated with neck pain. Sixty-five consecutive patients with cervical discopathy and coexisting degenerative changes were assessed pre-surgically. The mean pain duration was 31.7 SD 34.0 months. Patients completed the Polish versions of the Tampa Scale for Kinesiophobia (TSK-PL) on 2 occasions, and the following once: Neck Disability Index (NDI-PL), State-Trait Anxiety Inventory (STAI-PL), Coping Strategies Questionnaire (CSQ-PL), and the Visual Analogue Scale (VAS-PL). A high level of kinesiophobia was indicated in 81.5% and 87.7% of patients in first and second completion, respectively. Patients with high and low kinesiophobia differ in regards to the recreation section of NDI-PL (p=0.012), gender (p=0.043), and sports activity (p=0.024). Correlations were identified between TSK-PL and marital status (p=0.023) and sports activity (p=0.024). Kinesiophobia levels are higher in patients with chronic cervical pain before surgical treatment. Fear of movement tends to be higher in women and among patients avoiding sports recreation before surgical treatment. Although sports activity and socio-demographic data are predictors of kinesiophobia, psychological, pain-related, and clinical data are not. These findings should be considered when planning rehabilitation after surgical treatment of cervical discopathy and coexisting degenerative changes.

    Chromatin-state analysis is widely applied in the studies of development and diseases. However, existing methods operate at a single length scale, and therefore cannot distinguish large domains from isolated elements of the same type. To overcome this limitation, we present a hierarchical hidden Markov model, diHMM, to systematically annotate chromatin states at multiple length scales. We apply diHMM to analyse a public ChIP-seq data set. diHMM not only accurately captures nucleosome-level information, but identifies domain-level states that vary in nucleosome-level state composition, spatial distribution and functionality. The domain-level states recapitulate known patterns such as super-enhancers, bivalent promoters and Polycomb repressed regions, and identify additional patterns whose biological functions are not yet characterized. By integrating chromatin-state information with gene expression and Hi-C data, we identify context-dependent functions of nucleosome-level states. Thus, diHMM provides a powerful tool for investigating the role of higher-order chromatin structure in gene regulation.

    Interest in finding natural antioxidants for use in food or medical materials to prevent free radical imbalance has increased considerably over the past years. The aim of this research was to evaluate changes in glycemic control and psychological state of patients with type 2 diabetes mellitus (T2DM) after use of antioxidant plant preparations. Fifty-six patients with T2DM were randomly allocated to receive standardized Ginkgo biloba L. leaves dry extract, green tea dry extract, or placebo capsules. Diabetes glycemic control measured as glycated hemoglobin (HbA1c) level, antioxidant state and psychological data were evaluated at baseline, after 9 and 18 months of using either antioxidant preparations or placebo. The level of perceived stress lowered significantly after 9 months (p = 0.038) and 18 months (p = 0.030), and the psychological aspect of quality of life significantly improved after 18 months (p = 0.019) of use of G. biloba extrac. No significant differences were detected after using green tea extract. In patients using placebo, significant lowering of HbA1c level was observed after 18 months (p = 0.017). In conclusion, antioxidant G. biloba leaf extract exhibited a mild effect on psychological state and a trend of improving glycemic control in patients with type 2 diabetes mellitus.

  18. THE RECOMPOSITION OF THE SCALES OF GOVERNANCE, STATE AND TERRITORIAL DEVELOPMENT IN BRAZIL

    Elson Luciano Silva Pires

    2015-07-01

    Full Text Available The global process of spatial rearrangement of human actions put in focus new themes and scales of analysis of the territory, such as local and regional, that simultaneous to the scale of the union of countries in blocks, result in opening possibilities for multilevel governance structures, or impose redefinition of the roles of the states. It is in this scenario, that the territory emerges as a source or strategy of political power and economic, of dispute of groups or social classes whom have different interests and often conflicting. In this sense, the theme on State and public intervention is important because it constitutes the scale of phenomena arising from the decisional institutional universe of the political territorially centralized, when growing the importance of the decentralization of state power. The aim of this paper is to show that the recomposition of the scales of global, regional and local phenomena define significant parts for the management of territorial policies, while grow the challenges of cooperation and coordination. Thus, we reiterate here the relevance of the contributions from political geography and institutionalist political economics, analyzing, each in its own way, as how political phenomena and institutional forms are territorialized and cut out significant spaces of governance of social relations, their interests, commitments, conflicts, control, domination and power.

    The work studies the issues associated with the construction of the equation of state (EOS) taking due account of substance behavior in the critical region and associated with the scaling theory of critical phenomena (ST). The authors have developed a new version of the scaling hypothesis; this approach uses the following: a) substance equation of state having a form of a Schofield-Litster-Ho linear model (LM) and b) the Benedek hypothesis. The Benedek hypothesis has found a similar behavior character for a number of properties (isochoric and isobaric heat capacities, isothermal compressibility coefficient) at critical and near-critical isochors in the vicinity of the critical point. A method is proposed to build the fundamental equation of state (FEOS) which satisfies the ST power laws. The FEOS building method is verified by building the equation of state for argon within the state parameters range: up to 1000 MPa in terms of pressure, and from 83.056 К to 13000 К in terms of temperature. The executed comparison with the fundamental equations of state of Stewart-Jacobsen (1989), of Kozlov at al (1996), of Tegeler-Span-Wagner (1999), of has shown that the FEOS describes the known experimental data with an essentially lower error.

    Various types of neural-based signals, such as EEG, local field potentials and intracellular synaptic potentials, integrate multiple sources of activity distributed across large assemblies. They have in common a power-law frequency-scaling structure at high frequencies, but it is still unclear whether this scaling property is dominated by intrinsic neuronal properties or by network activity. The latter case is particularly interesting because if frequency-scaling reflects the network state it could be used to characterize the functional impact of the connectivity. In intracellularly recorded neurons of cat primary visual cortex in vivo, the power spectral density of V(m) activity displays a power-law structure at high frequencies with a fractional scaling exponent. We show that this exponent is not constant, but depends on the visual statistics used to drive the network. To investigate the determinants of this frequency-scaling, we considered a generic recurrent model of cortex receiving a retinotopically organized external input. Similarly to the in vivo case, our in computo simulations show that the scaling exponent reflects the correlation level imposed in the input. This systematic dependence was also replicated at the single cell level, by controlling independently, in a parametric way, the strength and the temporal decay of the pairwise correlation between presynaptic inputs. This last model was implemented in vitro by imposing the correlation control in artificial presynaptic spike trains through dynamic-clamp techniques. These in vitro manipulations induced a modulation of the scaling exponent, similar to that observed in vivo and predicted in computo. We conclude that the frequency-scaling exponent of the V(m) reflects stimulus-driven correlations in the cortical network activity. Therefore, we propose that the scaling exponent could be used to read-out the "effective" connectivity responsible for the dynamical signature of the population signals measured

    In this paper, we study the random field Ising model (RFIM) in an external magnetic field h . A computationally efficient graph-cut method is used to study ground state (GS) morphologies in this system for three different disorder types: Gaussian, uniform and bimodal. We obtain the critical properties of this system and find that they are independent of the disorder type. We also study GS morphologies via pinned-cluster distributions, which are scale-free at criticality. The spin-spin correlation functions (and structure factors) are characterized by a roughness exponent [Formula: see text]. The corresponding scaling function is universal for all disorder types and independent of h.

    To document the reliability, construct and nomological validity of the perceived Social Stigmatisation (STIG) scale in the older adult population. Cross-sectional survey. Primary medical health services clinics. Probabilistic sample of older adults aged 65 years and over waiting for medical services in the general medical sector (n = 1765). Perceived social stigma against people with a mental health problem was measured using the STIG scale composed of seven indicators. A second-order measurement model of perceived social stigma fitted adequately the observed data. The reliability of the STIG scale was 0.83. According to our results, 39.6% of older adults had a significant level of perceived social stigma against people with a mental health problem. RESULTS showed that the perception of social stigma against mental health problems was not significantly associated with a respondent gender and age. RESULTS also showed that the perception of social stigma against the mental health problems was directly associated with the respondents' need for improved mental health (b = -0.10) and indirectly associated with their use of primary medical health services for psychological distress symptoms (b = -0.07). RESULTS lead us to conclude that social stigma against mental disorders perceived by older adults may limit help-seeking behaviours and warrants greater public health and public policy attention. Also, results lead us to conclude that physicians should pay greater attention to their patients' attitudes against mental disorders in order to identify possible hidden mental health problems.

    The main goal of this study was to propose and validate a tool to quantify the psychological readiness of athletes to return to sport following traumatic shoulder instability and conservative or surgical management. «Knee» was replaced by the term «shoulder» in the Anterior Cruciate Ligament-Return to Sport after Injury scale. This pilot test of the Shoulder Instability-Return to Sport after Injury scale (SIRSI) was performed in a group of athletes who underwent surgery for post-traumatic chronic anterior shoulder instability. The final version was then validated according to the international COSMIN methodology. A retrospective study was performed including all rugby players who had reported an episode of instability between 2012 and 2013. The WOSI and the Walch-Duplay scales were used as reference questionnaires. Sixty-two patients were included, mean age 26 ± 5.2 years old, 5 women/57 men. Patients were professional or competitive athletes (70.9%) and followed-up for 4.6 ± 1.6 years after the first episode of shoulder instability. Shoulder surgery was performed in 30/62 (48.4%) patients, a mean 1.6 ± 1.2 years after the first episode of instability. The SIRSI was strongly correlated with the reference questionnaires (r = 0.80, p shoulder instability, whether they undergo surgery or not. III.

    Addressing climate change in the United States requires enactment of national, state and local mitigation and adaptation policies. The success of these initiatives depends on public opinion, policy support and behaviours at appropriate scales. Public opinion, however, is typically measured with national surveys that obscure geographic variability across regions, states and localities. Here we present independently validated high-resolution opinion estimates using a multilevel regression and poststratification model. The model accurately predicts climate change beliefs, risk perceptions and policy preferences at the state, congressional district, metropolitan and county levels, using a concise set of demographic and geographic predictors. The analysis finds substantial variation in public opinion across the nation. Nationally, 63% of Americans believe global warming is happening, but county-level estimates range from 43 to 80%, leading to a diversity of political environments for climate policy. These estimates provide an important new source of information for policymakers, educators and scientists to more effectively address the challenges of climate change.

Dorogovtsev et al, Rev. Mod. Phys., 80, 1275 (2008. It is shown that the Ising model on the proposed graphs with interaction intensities of arbitrary signs with probability one is in a paramagnetic state at sufficiently high finite values of the temperature. For the same graphs, the bond percolation model with probability one is in a nonpercolative state for positive values of the percolation probability. These results and their possible extensions are also discussed.

    Knowledge and awareness about childhood autism is low among health care workers and the general populace in Nigeria. Poor knowledge about childhood autism among final year medical, nursing and psychology students who would form tomorrow's child health care professionals can compromise early recognition and interventions that are known to improve prognosis in childhood autism. Educational factors that could be influencing knowledge about childhood autism among these future health care professionals are unknown. This study assessed knowledge about childhood autism among final year undergraduate medical, nursing and psychology students in south-eastern Nigeria and determined the factors that could be influencing such knowledge. One hundred final year undergraduate students were randomly selected from each of the Departments of Medicine, Nursing Science and Psychology respectively of University of Nigeria, Enugu State, Nigeria making a sample size of three hundred. A socio-demographic questionnaire and knowledge about childhood autism among health workers (KCAHW) questionnaire were administered to the students. The total mean score for the three groups of students on the KCAHW questionnaire was 10.67+/-3.73 out of a possible total score of 19, with medical, nursing and psychology students having total mean scores of 12.24+/-3.24, 10.76+/-3.50 and 9.01+/-3.76 respectively. The mean scores for the three groups showed statistically significant difference for domain 1 (p=0.000), domain 3 (p=0.029), domain 4 (p=0.000) and total score (p=0.000), with medical students more likely to recognise symptoms and signs of autism compared to nursing and psychology students. The mean score in domain 2 did not show statistically significant difference among the three groups (p=0.769). The total score on the KCAHW questionnaire is positively correlated with the number of weeks of posting in psychiatry (r=0.319, p=0.000) and the number of weeks of posting in paediatrics (r=0.372, p=0

    The BOLD signal measured in fMRI studies depends not only on neuronal activity, but also on other parameters like tissue vascularization, which may vary between subjects and between brain regions. A correction for variance from vascularization effects can thus lead to improved group statistics by reducing inter-subject variability. The fractional amplitude of low-frequency fluctuations (fALFF) as determined in a resting-state scan has been shown to be dependent on vascularization. Here we present a correction method termed RESCALE (REsting-state based SCALing of parameter Estimates) that uses local information to compute a voxel-wise scaling factor based on the correlation structure of fALFF and task activation parameter estimates from within a cube of 3 × 3 × 3 surrounding that voxel. The scaling method was used on a visuo-motor paradigm and resulted in a consistent increase in t-values in all task-activated cortical regions, with increases in peak t-values of 37.0% in the visual cortex and 12.7% in the left motor cortex. The RESCALE method as proposed herein can be easily applied to all task-based fMRI group studies provided that resting-state data for the same subject group is also acquired. PMID:23266702

    2009-06-01

    In this article an overview is presented of the emergence of medical psychology in the care of somatically ill patients. The situation in the Netherlands can be considered as prototypical. For 60 years, clinical psychologists have been working in general, teaching and academic hospitals. Nowadays, they are an integrated non-medical specialism working in the medical setting of hospitals in the Netherlands, and are a full-member of the medical board. This paper discusses several topics: the position of the general hospital in the health care system in the Netherlands, the emergence of medical psychology in Dutch hospitals, the role of the professional association of medical psychologists, and the characteristics of patients seen by clinical psychologists. Following the discussion about the situation of medical psychology in other countries, recommendations are formulated for the further development of medical psychology in the Netherlands as well as in other countries.

    This study examined the relationships among social media use for information, self-status seeking and socializing, body image, self-esteem, and psychological well-being, and some cultural effects moderating these relationships. Americans (n = 502) and Koreans (n = 518) completed an online survey. The main findings showed that (a) social media use for information about body image is negatively related to body satisfaction in the United States and Korea, while social media use for self-status seeking regarding body image is positively related to body satisfaction only in Korea; and (b) body satisfaction has direct and indirect positive effects on psychological well-being manifested in similar ways in the United States and Korea. Implications and future research directions are discussed.

    Analogue scale modelling of extensional tectonic processes such as rifting and basin opening has been numerously conducted. Among the controlling factors, gravitational acceleration (g) on the scale models was regarded as a constant (Earth's gravity) in the most of the analogue model studies, and only a few model studies considered larger gravitational acceleration by using a centrifuge (an apparatus generating large centrifugal force by rotating the model at a high speed). Although analogue models using a centrifuge allow large scale-down and accelerated deformation that is derived by density differences such as salt diapir, the possible model size is mostly limited up to 10 cm. A state-of-the-art centrifuge installed at the KOCED Geotechnical Centrifuge Testing Center, Korea Advanced Institute of Science and Technology (KAIST) allows a large surface area of the scale-models up to 70 by 70 cm under the maximum capacity of 240 g-tons.

    Soil moisture is an essential climate variable influencing land atmosphere interactions, an essential hydrologic variable impacting rainfall runoff processes, an essential ecological variable regulating net ecosystem exchange, and an essential agricultural variable constraining food security. Large-scale soil moisture monitoring has advanced in recent years creating opportunities to transform scientific understanding of soil moisture and related processes. These advances are being driven by researchers from a broad range of disciplines, but this complicates collaboration and communication. For some applications, the science required to utilize large-scale soil moisture data is poorly developed. In this review, we describe the state of the art in large-scale soil moisture monitoring and identify some critical needs for research to optimize the use of increasingly available soil moisture data. We review representative examples of 1) emerging in situ and proximal sensing techniques, 2) dedicated soil moisture remote sensing missions, 3) soil moisture monitoring networks, and 4) applications of large-scale soil moisture measurements. Significant near-term progress seems possible in the use of large-scale soil moisture data for drought monitoring. Assimilation of soil moisture data for meteorological or hydrologic forecasting also shows promise, but significant challenges related to model structures and model errors remain. Little progress has been made yet in the use of large-scale soil moisture observations within the context of ecological or agricultural modeling. Opportunities abound to advance the science and practice of large-scale soil moisture monitoring for the sake of improved Earth system monitoring, modeling, and forecasting.

    NASA's Energy and Water Cycle Study (NEWS) program fosters collaborative research towards improved quantification and prediction of water and energy cycle consequences of climate change. In order to measure change, it is first necessary to describe current conditions. The goal of the NEWS Water and Energy Cycle Climatology project is to develop "state of the global water cycle" and "state of the global energy cycle" assessments based on data from modern ground and space based observing systems and data integrating models. The project is a multiinstitutional collaboration with more than 20 active contributors. This presentation will describe results of the first stage of the water budget analysis, whose goal was to characterize the current state of the water cycle on mean monthly, continental scales. We examine our success in closing the water budget within the expected uncertainty range and the effects of forcing budget closure as a method for refining individual flux estimates.

    Psychological flexibility has been suggested as a fundamental process in health. The Psychological Inflexibility in Pain Scale (PIPS) is one of the scales employed for assessing psychological inflexibility in pain patients. The aim of this study was to validate the Spanish version of the PIPS and secondly, to compare it to two other psychological constructs, the acceptance of pain and mindfulness scales. The PIPS was translated into Spanish by two bilingual linguistic experts, and then, back-translated into English to assess for equivalence. The final Spanish version was administered along with the Pain Visual Analogue Scale, Fibromyalgia Impact Questionnaire, Hospital Anxiety Depression Scale, Pain Catastrophizing Scale, Chronic Pain Acceptance Questionnaire and the Mindful Attention Awareness Scale, to 250 Spanish patients with fibromyalgia. Face validity, construct validity, reliability (internal consistency and test-retest) and convergent validity were tested. Also a multiple regression analysis was carried out.The usual guidelines have been followed for cross-cultural adaptations. Data were very similar to the ones obtained in the original PIPS version. The construct validity confirmed the original two-components solution which explained 61.6% of the variance. The Spanish PIPS had good test-retest reliability (intraclass correlation coefficient 0.97) and internal consistency reliability (Cronbach's alpha: 0.90). The Spanish PIPS' score correlated significantly with worse global functioning (r = 0.55), anxiety (r = 0.54), depression (r = 0.66), pain catastrophizing (r = 0.62), pain acceptance (r = -0.72) and mindfulness (r = -0.47), as well as correlating modestly with pain intensity (r = 0.12). The multiple regression analyses showed that psychological inflexibility, acceptance and mindfulness are not overlapped. The Spanish PIPS scale appears to be a valid and reliable instrument for the evaluation of psychological inflexibility among a sample of fibromyalgia

    Full Text Available School membership appears to be an important factor in explaining the relationship between students and schools, including school staff. School membership is associated with several school-related outcomes, such as academic performance and expectations. Most studies on school membership have been conducted in developed countries. The Psychological Sense of School Membership (PSSM scale (18 items: 13 positively worded items, 5 negatively worded items has been widely used to measure this construct, but no studies regarding its validity and reliability have been conducted in Spanish-speaking Latin American countries. This study investigates the psychometric properties, factor structure and reliability of this scale in a sample of 1250 early adolescents in Chile. Both exploratory and confirmatory factor analyses provide evidence of an excellent fit for a one-factor solution after removing the negatively worded items. The internal consistency of this new abbreviated version was 0.92. The association analyses demonstrated that high school membership was associated with better academic performance, stronger school bonding, a reduced likelihood of school misbehavior and reduced likelihood of substance use. Analyses showed support for the reliability and validity of the PSSM among Chilean adolescents.

  4. Uniform sampling of steady states in metabolic networks: heterogeneous scales and rounding.

    Directory of Open Access Journals (Sweden)

    Daniele De Martino

    Full Text Available The uniform sampling of convex polytopes is an interesting computational problem with many applications in inference from linear constraints, but the performances of sampling algorithms can be affected by ill-conditioning. This is the case of inferring the feasible steady states in models of metabolic networks, since they can show heterogeneous time scales. In this work we focus on rounding procedures based on building an ellipsoid that closely matches the sampling space, that can be used to define an efficient hit-and-run (HR Markov Chain Monte Carlo. In this way the uniformity of the sampling of the convex space of interest is rigorously guaranteed, at odds with non markovian methods. We analyze and compare three rounding methods in order to sample the feasible steady states of metabolic networks of three models of growing size up to genomic scale. The first is based on principal component analysis (PCA, the second on linear programming (LP and finally we employ the Lovazs ellipsoid method (LEM. Our results show that a rounding procedure dramatically improves the performances of the HR in these inference problems and suggest that a combination of LEM or LP with a subsequent PCA perform the best. We finally compare the distributions of the HR with that of two heuristics based on the Artificially Centered hit-and-run (ACHR, gpSampler and optGpSampler. They show a good agreement with the results of the HR for the small network, while on genome scale models present inconsistencies.

    In the light of recent theoretical developments, the paper presents an accurate characterization of anomalous thermodynamic behavior of xenon, helium 4, helium 3, carbon dioxide, steam and oxygen in the critical region. This behavior is associated with long range fluctuations in the system and the physical properties depend primarily on a single variable, namely, the correlation length. A description of the thermodynamic behavior of fluids in terms of scaling laws is formulated, and the two successfully used scaled equations of state (NBS equation and Linear Model parametric equation) are compared. Methods for fitting both equations to experimental equation of state data are developed and formulated, and the optimum fit for each of the two scaled equations of the above gases are presented and the results are compared. By extending the experimental data for the above one-component fluids to partially miscible binary liquids, superfluid liquid helium, ferromagnets and solids exhibiting order-disorder transitions, the principle of universality is concluded. Finally by using this principle, the critical regions for nine additional fluids are described.

    1999-01-01

    Jackson and Marsh (1996) reported the development of a Flow State Scale (FSS) for use in sport and physical activity. The FSS contains 36 items measuring the nine dimensions of flow described by Csikszentmihalyi (1990, 1993). Jackson and Marsh reported high internal consistency estimates for the subscales and evidence for nine first-order factors and one second-order factor when confirmatory factor analytic techniques were used. The present study extended this validation work by subjecting the data from the original sample (N = 394) of elite younger athletes and a subsequent sample (N = 398) of older athletes to Rasch analysis. These Rasch analyses showed quite clearly that the flow dimensions may be conceptualised as a continuum with "autotelic experience" being experienced more readily than dimensions such as "transformation of time", a state that may only be encountered at the height of a deep flow experience. The Rasch analyses provide useful additional information about the areas of the flow continuum tapped by the items and scales of the FSS and, in so doing, help to confirm the construct validity and generalisability of the scale itself.

    Stress is known to induce large-scale neural modulations. However, its neural effect once the stressor is removed and how it relates to subjective experience are not fully understood. Here we used a statistically sound data-driven approach to investigate alterations in large-scale resting-state functional connectivity (rsFC) induced by acute social stress. We compared rsfMRI profiles of 57 healthy male subjects before and after stress induction. Using a parcellation-based univariate statistical analysis, we identified a large-scale rsFC change, involving 490 parcel-pairs. Aiming to characterize this change, we employed statistical enrichment analysis, identifying anatomic structures that were significantly interconnected by these pairs. This analysis revealed strengthening of thalamo-cortical connectivity and weakening of cross-hemispheral parieto-temporal connectivity. These alterations were further found to be associated with change in subjective stress reports. Integrating report-based information on stress sustainment 20 minutes post induction, revealed a single significant rsFC change between the right amygdala and the precuneus, which inversely correlated with the level of subjective recovery. Our study demonstrates the value of enrichment analysis for exploring large-scale network reorganization patterns, and provides new insight on stress-induced neural modulations and their relation to subjective experience.

  8. Earthquake Hazard and Risk Assessment Based on Unified Scaling Law for Earthquakes: State of Gujarat, India

    2017-03-01

    The Gujarat state of India is one of the most seismically active intercontinental regions of the world. Historically, it has experienced many damaging earthquakes including the devastating 1819 Rann of Kachchh and 2001 Bhuj earthquakes. The effect of the later one is grossly underestimated by the Global Seismic Hazard Assessment Program (GSHAP). To assess a more adequate earthquake hazard for the state of Gujarat, we apply Unified Scaling Law for Earthquakes (USLE), which generalizes the Gutenberg-Richter recurrence relation taking into account naturally fractal distribution of earthquake loci. USLE has evident implications since any estimate of seismic hazard depends on the size of the territory considered and, therefore, may differ dramatically from the actual one when scaled down to the proportion of the area of interest (e.g. of a city) from the enveloping area of investigation. We cross-compare the seismic hazard maps compiled for the same standard regular grid 0.2° × 0.2° (1) in terms of design ground acceleration based on the neo-deterministic approach, (2) in terms of probabilistic exceedance of peak ground acceleration by GSHAP, and (3) the one resulted from the USLE application. Finally, we present the maps of seismic risks for the state of Gujarat integrating the obtained seismic hazard, population density based on India's Census 2011 data, and a few model assumptions of vulnerability.

    This study examined the validity of a state version of the Social Physique Anxiety Scale (Hart, Leary & Rejeski, 1989) by conducting tests of concurrent and discriminative validation. Participants were four separate samples of young women (N=221) who exercised ≤ 2 days/week and who participated in various experiments examining body image and self-presentation. Participants' scores on the state SPAS (S-SPAS) were significantly correlated, in expected directions, with scores on both trait and state measures of body image and self-presentation, and with body mass index (BMI). In addition, S-SPAS scores discriminated between women who exercised in a mixed-sex versus a same-sex environment, but trait SPAS scores did not. Together, these results provide evidence of construct validity of a state version of the SPAS and demonstrate that social physique anxiety can be conceptualized and measured as a situational variable. The S-SPAS, rather than the trait SPAS, should be employed in experiments designed to detect differences in state social physique anxiety. Copyright © 2010 Elsevier Ltd. All rights reserved.

    2016-02-01

    The collective dynamics of Kuramoto oscillators with a positive correlation between the incoherent and fully coherent domains in clustered scale-free networks is studied. Emergence of chimera states for the onsets of explosive synchronization transition is observed during an intermediate coupling regime when degree-frequency correlation is established for the hubs with the highest degrees. Diagnostic of the abrupt synchronization is revealed by the intrinsic spectral properties of the network graph Laplacian encoded in the heterogeneous phase space manifold, through extensive analytical investigation, presenting realistic MC simulations of nonlocal interactions in discrete time dynamics evolving on the network.

    Probing electronic structure of atomically well controlled surface of Perovskite-type 3d transition-metal oxides have been attracting much interest because of their intriguing emergent physical properties by heterostructure engineering. In this study, we have especially focused on SrVO3, where importance of correlation effects has been considered. We successfully obtained atomically flat surfaces of SrVO3, which gave us the great opportunity to visualize correlated electronic state at atomic scale by means of spectroscopic imaging scanning tunneling spectroscopy. Based on the experimental data, we discuss spectroscopic signature of many body effects on the surface of SrVO3 system.

    To benchmark the psychological state and physical rehabilitation of patients who have sustained limb loss as a result of terrorist activity in Northern Ireland and to determine their satisfaction with the period of primary prosthetic rehabilitation and the artificial limb. All patients who sustained limb loss as a result of the Troubles and were referred to our rehabilitation centre were sent a questionnaire. The main outcome measures were the SIGAM mobility grades, the General Health Questionnaire (GHQ12) and three screening questions for Post Traumatic Stress Disorder (PTSD). Out of a 66% response rate, 52 (69%) patients felt that the period of primary prosthetic rehabilitation was adequate; 32 (54%) lower limb amputees graded themselves SIGAM C or D; 45 (60%) patients stated that they were still having significant stump pain. Significant stump pain was associated with poorer mobility. Nine (56%) upper limb amputees used their prosthetic limb in a functional way; 33 (44%) patients showed "psychiatric caseness" on the GHQ 12 and 50 (67%) had symptoms of PTSD. Most patients felt that the period of physical rehabilitation had been adequate; those who did not were more likely to be having ongoing psychological problems. A high percentage of patients continue to have psychological problems and stump pain.

    During recent decades, artisanal and small-scale mining (ASM) in Africa has increased tremendously. An unknown but significant part is constituted by activities that are not based on legally registered mining licenses. The division of formal and informal ASM is, however, dissolved in the marketing...... chain where trading channels are intertwined: traders buy from miners with and without a license. So far state institutions and civil society organizations have endeavoured to ‘formalize’ the informal sector by focusing on relatively isolated entry points in the ASM chain from production to consumption...... dependency relations, barriers for poverty eradication and agricultural development. The paper outlines the previous debate on formalization and maps out the territorial and organizational configuration of the present ASM gold chain in Tanzania and Ghana. On this basis we maintain that state action...

    The aim of this study was to investigate the effects of exercise dependence on the psychological health of Chinese college students. A total of 1601 college students from three universities in Hunan, China, were selected as research subjects. Several measurement scales, including the Exercise Addiction Inventory, the State-Trait Anxiety Inventory, the Center for Epidemiologic Studies Depression Scale, and the Subjective Well-being Scale, were used to survey the psychological health problem of these students and to analyze the effects of exercise dependence on their psychological health. Exercise dependence, based on the structural equation model analysis, can positively influence state anxiety (Pstudents. By contrast, exercise dependence negatively influences students' self-satisfaction (Phealth of college students. Further research using multi-dimensional exercise addiction scales should be conducted to identify all the negative effects of exercise addiction factors on psychological health.

    2013-09-01

    We determined the impact of premigration circumstances on postmigration psychological distress and self-rated physical health among Latino immigrants. We estimated ordinary least squares and logistic regression models for Latino immigrants in the 2002-2003 National Latino and Asian American Study (n = 1603). Mean psychological distress scores (range = 10-50) were 14.8 for women and 12.7 for men; 35% of women and 27% of men reported fair or poor physical health. A third of the sample reported having to migrate; up to 46% reported unplanned migration. In multivariate analyses, immigration-related stress was significantly associated with psychological distress, but not with self-rated health, for both Latino men and women. Having to migrate was associated with increased psychological distress for Puerto Rican and Cuban women respondents and with poorer physical health for Puerto Rican migrant men. Unplanned migration was significantly associated with poorer physical health for all Latina women respondents. The context of both pre- and postmigration has an impact on immigrant health. Those involved in public health research, policy, and practice should consider variation in immigrant health by migration circumstances, including the context of exit and other immigration-related stressors.

    2017-11-01

    Full Text Available In the continuous mode of cell culture, a constant flow carrying fresh media replaces culture fluid, cells, nutrients and secreted metabolites. Here we present a model for continuous cell culture coupling intra-cellular metabolism to extracellular variables describing the state of the bioreactor, taking into account the growth capacity of the cell and the impact of toxic byproduct accumulation. We provide a method to determine the steady states of this system that is tractable for metabolic networks of arbitrary complexity. We demonstrate our approach in a toy model first, and then in a genome-scale metabolic network of the Chinese hamster ovary cell line, obtaining results that are in qualitative agreement with experimental observations. We derive a number of consequences from the model that are independent of parameter values. The ratio between cell density and dilution rate is an ideal control parameter to fix a steady state with desired metabolic properties. This conclusion is robust even in the presence of multi-stability, which is explained in our model by a negative feedback loop due to toxic byproduct accumulation. A complex landscape of steady states emerges from our simulations, including multiple metabolic switches, which also explain why cell-line and media benchmarks carried out in batch culture cannot be extrapolated to perfusion. On the other hand, we predict invariance laws between continuous cell cultures with different parameters. A practical consequence is that the chemostat is an ideal experimental model for large-scale high-density perfusion cultures, where the complex landscape of metabolic transitions is faithfully reproduced.

    We have demonstrated a generation of double-scale in a laser diode (LD)-pumped Yb:phosphate solid-state laser. The double-scale pulse with a spectrum bandwidth of 4.6 nm is obtained at a central wavelength of 1030 nm with maximum output power of 377 mW and 80 MHz repetition rate. The autocorrelation function of the double-scale pulse contained a 510 fs short peak and 12.51 ps long pedestal. To our best knowledge, this is the first demonstration of a double-scale pulse mode-locked solid-state laser.

  2. The Tectonics Model of Coronal Heating: Unsteady Dynamics and Scaling in Statistical Steady State

    Science.gov (United States)

    Ng, C. S.; Lin, L.; Bhattacharjee, A.

    2009-11-01

    The tectonics model of coronal heating, proposed by Priest et al. [Astrophys. J., 576, 533 (2002)] envisions coronal heating caused by a hierarchy of current sheets produced by the movement of a myriad of flux elements in the magnetic carpet covering the Sun. We have recently obtained new scaling results in two dimensions (2D) suggesting that the heating rate becomes independent of resistivity in a statistical steady state [C. S. Ng and A. Bhattacharjee, Astrophys. J., 675, 899 (2008)]. Our numerical work has now been extended to 3D. Random photospheric footpoint motion is applied to obtain converged average coronal heating rates. In the large Lundquist number limit, we find that the heating rate is independent of the Lundquist number, with average magnetic energy saturating at a constant level due to the formation of strong current layers and subsequent disruptions. In this talk, we will present our latest numerical results from large-scale 3D simulations, and discuss differences with previous scaling laws.

    2018-01-01

    Understanding the drivers of biological invasions is critical for preserving aquatic biodiversity. Stream fishes make excellent model taxa for examining mechanisms driving species introduction success because their distributions are naturally limited by catchment boundaries. In this study, we compared the relative importance of catchment-scale abiotic and biotic predictors of native and nonindigenous minnow (Cyprinidae) richness in 170 catchments throughout the eastern United States. We compared historic and contemporary cyprinid distributional data to determine catchment-wise native/nonindigenous status for 152 species. Catchment-scale model predictor variables described natural (elevation, precipitation, flow accumulation) and anthropogenic (developed land cover, number of dams) abiotic features, as well as native congener richness. Native congener richness may represent either biotic resistance via interspecific competition, or trait preadaptation according to Darwin's naturalisation hypothesis. We used generalised linear mixed models to examine evidence supporting the relative roles of abiotic and biotic predictors of cyprinid introduction success. Native congener richness was positively correlated with nonindigenous cyprinid richness and was the most important variable predicting nonindigenous cyprinid richness. Mean elevation had a weak positive effect, and effects of other abiotic factors were insignificant and less important. Our results suggest that at this spatial scale, trait preadaptation may be more important than intrageneric competition for determining richness of nonindigenous fishes.

    Full Text Available The OAV questionnaire has been developed to integrate research on altered states of consciousness (ASC. It measures three primary and one secondary dimensions of ASC that are hypothesized to be invariant across ASC induction methods. The OAV rating scale has been in use for more than 20 years and applied internationally in a broad range of research fields, yet its factorial structure has never been tested by structural equation modeling techniques and its psychometric properties have never been examined in large samples of experimentally induced ASC.The present study conducted a psychometric evaluation of the OAV in a sample of psilocybin (n = 327, ketamine (n = 162, and MDMA (n = 102 induced ASC that was obtained by pooling data from 43 experimental studies. The factorial structure was examined by confirmatory factor analysis, exploratory structural equation modeling, hierarchical item clustering (ICLUST, and multiple indicators multiple causes (MIMIC modeling. The originally proposed model did not fit the data well even if zero-constraints on non-target factor loadings and residual correlations were relaxed. Furthermore, ICLUST suggested that the "oceanic boundlessness" and "visionary restructuralization" factors could be combined on a high level of the construct hierarchy. However, because these factors were multidimensional, we extracted and examined 11 new lower order factors. MIMIC modeling indicated that these factors were highly measurement invariant across drugs, settings, questionnaire versions, and sexes. The new factors were also demonstrated to have improved homogeneities, satisfactory reliabilities, discriminant and convergent validities, and to differentiate well among the three drug groups.The original scales of the OAV were shown to be multidimensional constructs. Eleven new lower order scales were constructed and demonstrated to have desirable psychometric properties. The new lower order scales are most likely better suited to

    Major depressive disorder (MDD) often emerges during adolescence, a critical period of brain development. Recent resting-state fMRI studies of adults suggest that MDD is associated with abnormalities within and between resting-state networks (RSNs). Here we tested whether adolescent MDD is characterized by abnormalities in interactions among RSNs. Participants were 55 unmedicated adolescents diagnosed with MDD and 56 matched healthy controls. Functional connectivity was mapped using resting-state fMRI. We used the network-based statistic (NBS) to compare large-scale connectivity between groups and also compared the groups on graph metrics. We further assessed whether group differences identified using nodes defined from functionally defined RSNs were also evident when using anatomically defined nodes. In addition, we examined relations between network abnormalities and depression severity and duration. Finally, we compared intranetwork connectivity between groups and assessed the replication of previously reported MDD-related abnormalities in connectivity. The NBS indicated that, compared with controls, depressed adolescents exhibited reduced connectivity (pdepression was significantly correlated with reduced connectivity in this set of network interactions (p=0.020, corrected), specifically with reduced connectivity between components of the dorsal attention network. The dorsal attention network was also characterized by reduced intranetwork connectivity in the MDD group. Finally, we replicated previously reported abnormal connectivity in individuals with MDD. In summary, adolescents with MDD show hypoconnectivity between large-scale brain networks compared with healthy controls. Given that connectivity among these networks typically increases during adolescent neurodevelopment, these results suggest that adolescent depression is associated with abnormalities in neural systems that are still developing during this critical period.

    The May 2015 release of the report of the President's Task Force on 21st Century Policing highlighted a fundamental change in the issues dominating discussions about policing in America. That change has moved discussions away from a focus on what is legal or effective in crime control and toward a concern for how the actions of the police influence public trust and confidence in the police. This shift in discourse has been motivated by two factors-first, the recognition by public officials that increases in the professionalism of the police and dramatic declines in the rate of crime have not led to increases in police legitimacy, and second, greater awareness of the limits of the dominant coercive model of policing and of the benefits of an alternative and more consensual model based on public trust and confidence in the police and legal system. Psychological research has played an important role in legitimating this change in the way policymakers think about policing by demonstrating that perceived legitimacy shapes a set of law-related behaviors as well as or better than concerns about the risk of punishment. Those behaviors include compliance with the law and cooperation with legal authorities. These findings demonstrate that legal authorities gain by a focus on legitimacy. Psychological research has further contributed by articulating and demonstrating empirical support for a central role of procedural justice in shaping legitimacy, providing legal authorities with a clear road map of strategies for creating and maintaining public trust. Given evidence of the benefits of legitimacy and a set of guidelines concerning its antecedents, policymakers have increasingly focused on the question of public trust when considering issues in policing. The acceptance of a legitimacy-based consensual model of police authority building on theories and research studies originating within psychology illustrates how psychology can contribute to the development of evidence

    Two core but untested predictions of Positive Clinical Psychology (PCP) are that (1) Many psychiatric problems can be understood as one end of bipolar continua with well-being, and (2) that reducing psychiatric symptoms will provide an equal (near linear) decrease in risk for several other psychiatric variables, irrespective of position on continua. We test these predictions in relation to a purported well-being/depression continuum, as measured by the Center for Epidemiologic Studies-Depression (CES-D), a popular measure of depressive experiences in research and clinical practice. A large (N=4138), diverse sample completed the CES-D, which contains a mixture of negatively worded and positively worded items (e.g., "I felt sad," "I enjoyed life"). The latter are conventionally reverse scored to compute a total score. We first examined whether purportedly separate well-being and depression CES-D factors can be reconceptualised as a bipolar well-being/depression continuum. We then characterised the (linear or nonlinear) form of the relationship between this continuum and other psychiatric variables. Both predictions were supported. When controlling for shared method bias amongst positively worded items, a single factor well-being/depression continuum underlies the CES-D. Baseline levels on this continuum are found to have near linear relationships with changes in anxiety symptoms, aggression, and substance misuse over time, demonstrating that moving from depression to well-being on the CES-D provides an equal decrease in risk for several other psychological problems irrespective of position on the continuum. The CES-D does not measure well-being as comprehensively as established scales of well-being. Results support calls for mental health services to jointly focus on increasing well-being and reducing distress, and point to the value of early intervention and instilling resilience in order to prevent people moving away from high levels of well-being.

    We demonstrate an approach to measure the information flow between each pair of time series in resting-state functional MRI (fMRI) data of the human brain and subsequently recover its underlying network structure. By integrating dimensionality reduction into predictive time series modeling, large-scale Granger Causality (lsGC) analysis method can reveal directed information flow suggestive of causal influence at an individual voxel level, unlike other multivariate approaches. This method quantifies the influence each voxel time series has on every other voxel time series in a multivariate sense and hence contains information about the underlying dynamics of the whole system, which can be used to reveal functionally connected networks within the brain. To identify such networks, we perform non-metric network clustering, such as accomplished by the Louvain method. We demonstrate the effectiveness of our approach to recover the motor and visual cortex from resting state human brain fMRI data and compare it with the network recovered from a visuomotor stimulation experiment, where the similarity is measured by the Dice Coefficient (DC). The best DC obtained was 0.59 implying a strong agreement between the two networks. In addition, we thoroughly study the effect of dimensionality reduction in lsGC analysis on network recovery. We conclude that our approach is capable of detecting causal influence between time series in a multivariate sense, which can be used to segment functionally connected networks in the resting-state fMRI.

    Full Text Available Scaling-up solutions require learning and adapting lessons between locations and at different scales. To accomplish this, common metrics are vital to building a shared language. For California, this has meant careful financial, cradle-to-grave life-cycle assessment methods leading to carbon accounting in many avenues of government (via the Low Carbon Fuel Standard or the Cap and Trade program. These methods themselves interact, such as the use of carbon accounting for the resources needed to manage water and other key resources; the use of criteria air pollution monitoring to identify environmental injustices; and the use of carbon market revenues to address these inequalities, through investment in best available abatement technologies (BACT and in job creation in disadvantaged communities anticipated in the emerging clean energy sector.  Creating interdisciplinary partnerships across the UC Campuses and the National Laboratories to innovate science and technology is critical to scalable carbon neutrality solutions. As an example, we can build coordinated research and development programs across UC and California, with strong partnerships with the Federal government to coordinate and “multiply” resources that accelerate development and deployment. These partnerships should be strongly goal-focused, i.e., they are created to solve specific, large problems, to enable quantitatively measurable outcomes within energy generation, efficiency and CO2 abatement categories. Intersectoral partnerships should be fostered across campuses, laboratories, with state, federal and multi-lateral organizations funding to develop technologies and deploy solutions at scale. Integrated partnerships with industry are required to influence markets, deploy solutions, and create new industries and jobs.  Beyond California, we need to establish consortia with industry and foundations to deploy solutions at the regional, state, national, and international scale to

    Full Text Available Abstract Background Knowledge and awareness about childhood autism is low among health care workers and the general populace in Nigeria. Poor knowledge about childhood autism among final year medical, nursing and psychology students who would form tomorrow's child health care professionals can compromise early recognition and interventions that are known to improve prognosis in childhood autism. Educational factors that could be influencing knowledge about childhood autism among these future health care professionals are unknown. This study assessed knowledge about childhood autism among final year undergraduate medical, nursing and psychology students in south-eastern Nigeria and determined the factors that could be influencing such knowledge. Methods One hundred final year undergraduate students were randomly selected from each of the Departments of Medicine, Nursing Science and Psychology respectively of University of Nigeria, Enugu State, Nigeria making a sample size of three hundred. A socio-demographic questionnaire and knowledge about childhood autism among health workers (KCAHW questionnaire were administered to the students. Results The total mean score for the three groups of students on the KCAHW questionnaire was 10.67 ± 3.73 out of a possible total score of 19, with medical, nursing and psychology students having total mean scores of 12.24 ± 3.24, 10.76 ± 3.50 and 9.01 ± 3.76 respectively.

    2014-09-01

    The National Standards for High School Psychology Curricula (American Psychological Association, 2013b) require a teacher with considerable psychology content knowledge to teach high school psychology courses effectively. In this study, I examined the initial teaching credential requirements for high school psychology teachers in the 50 states plus the District of Columbia. Thirty-four states (the District of Columbia is included as a state) require the social studies credential to teach high school psychology. An analysis of the items on standardized tests used by states to validate the content knowledge required to teach social studies indicates little or no presence of psychology, a reflection of psychology's meager presence in the social studies teacher preparation curricula. Thus, new teachers with the social studies teaching credential are not prepared to teach high school psychology according to the National Standards. Approval of The College, Career, and Civic Life (C3) Framework for Social Studies State Standards: Guidance for Enhancing the Rigor of K-12 Civics, Economics, Geography, and History (National Council for the Social Studies, 2013) presents an opportunity to advocate for establishing a psychology credential in the 34 states.

    Carbon dioxide (CO2) storage in deep geologic formations is gaining ground as a potential measure for climate change mitigation. Such storage projects typically operate at large scales (~km), but their performance is often governed by smaller-scale (~m) heterogeneities. The large domain sizes prohibit detailed site characterization and dense monitoring networks, leading to predictions of CO2 migration and trapping based on rough geologic models that cannot capture preferential flow. Kalman Filtering can be used to improve these prior models by assimilating available monitoring data, thereby tracking system performance and reducing prediction uncertainty. However, for large systems with fine discretization, the number of unknowns is in the order of tens of thousands or more, in which case the textbook version of the Kalman Filter has prohibitively expensive computation and storage costs. We present the Compressed State Kalman Filter (CSKF) that can be effectively used for systems with a large number of unknowns to estimate the underlying heterogeneity and to predict the state of interest (e.g., pressure and CO2 saturation). The algorithm's computational efficiency is achieved by using a low-rank approximation of the covariance matrix, as well as a Jacobian-free approach. We demonstrate the estimation and computational performance of our method in a typical CO2 storage scenario with a spatially sparse monitoring network, but with multiple datasets obtained before and during CO2 injection. Our data assimilation framework provides an efficient and practical way to characterize geological formations intended for CO2 injection and storage using monitoring data commonly collected in field applications, as well as to quantify the reduction in uncertainty brought by different types of monitoring data.

    Abnormal grain growth (AGG) has been a common phenomenon during the ceramic or metallurgy processing since prehistoric times. However, usually it had been very difficult to grow big single crystal (centimeter scale over) by using the AGG method due to its so-called occasionality. Based on the AGG, a solid-state crystal growth (SSCG) method was developed. The greatest advantages of the SSCG technology are the simplicity and cost-effectiveness of the technique. But the traditional SSCG technology is still uncontrollable. This article first summarizes the history and current status of AGG, and then reports recent technical developments from AGG to SSCG, and further introduces a new seed-free, solid-state crystal growth (SFSSCG) technology. This SFSSCG method allows us to repeatedly and controllably fabricate large-scale single crystals with appreciable high quality and relatively stable chemical composition at a relatively low temperature, at least in (K0.5Na0.5)NbO3(KNN) and Cu-Al-Mn systems. In this sense, the exaggerated grain growth is no longer 'Abnormal' but 'Normal' since it is able to be artificially controllable and repeated now. This article also provides a crystal growth model to qualitatively explain the mechanism of SFSSCG for KNN system. Compared with the traditional melt and high temperature solution growth methods, the SFSSCG method has the advantages of low energy consumption, low investment, simple technique, composition homogeneity overcoming the issues with incongruent melting and high volatility. This SFSSCG could be helpful for improving the mechanical and physical properties of single crystals, which should be promising for industrial applications.

    2006-07-01

    This paper presents a comparative analysis of the steady-state performance of various designs for the electrical collector system of offshore wind farms and discusses the advantages and disadvantages of each of these designs and their application within large-scale offshore developments. A series of power systems studies were carried out for a proposed 1 GW wind farm off the northeast coast of Scotland, with the plant set to generate at a range of power outputs in order to investigate the impact on the loading and losses of the collector system. The impact on voltage level changes on the busbars within the wind farm under various conditions of reactive power demand, i.e. considering both typical squirrel-cage machines (with typically low lagging power factors) and modern doubly-fed generators (with capability to vary power factor in lagging/leading ranges), was also investigated. In addition, for collector system designs with redundant cables, contingency conditions of losing one of the cables to the hub end were investigated. The overall results have lead to consider the application of 'single-sided ring' designs for large-scale offshore wind farms since it achieves fewer losses and also provides greater adequacy and reliability. Finally, the authors introduce an alternative design based on 'single-sided ring' arrangement which seems a more suitable option taking into account potential economic barriers from the original one-to-one design.

    Full Text Available The objective of this study is a scale-dependent analysis of precipitation forecasts of the German Weather Service's (DWD non-hydrostatic Lokal-Modell (LM, COSMO-DE with regard to dynamical-statistical parameters and cloud properties. We propose a newly designed Dynamic State Index (DSI to evaluate precipitation processes. The DSI is presented in the context of a case study in the synoptic scale and in a statistical approach. The DSI quantitatively describes the deviation from a stationary, adiabatic and reversible solution of the primitive equations. As demonstrated by the example of the winter storm "Kyrill", the analysis of the vertical structure of the DSI gives a relation to the IPV-Thinking, introduced by Hoskins et al. (1985. Furthermore, the DSI-pattern features the characteristic filament-like structure of rainbands with embedded convective cells. In a next step the DSI is not only correlated with modelled precipitation but also with observed precipitation as well as cloud types. The absolute value of the DSI shows moderate correlations with hourly LM and high correlations with hourly COSMO-DE forecast data, based on 24 hour predictions. The statistical analysis of clouds with the index reveals a DSI-threshold, which is used to introduce a novel precipitation activity index of different cloud classes. In conclusion, the results highlight the importance of dynamical processes for the generation of rainfall.

    Extreme cold waves (ECWs) occurring over the conterminous United States (US) are studied through a systematic identification and documentation of their local synoptic structures, associated large-scale meteorological patterns (LMPs), and forcing mechanisms external to the US. Focusing on the boreal cool season (November-March) for 1950‒2005, a hierarchical cluster analysis identifies three ECW patterns, respectively characterized by cold surface air temperature anomalies over the upper midwest (UM), northwestern (NW), and southeastern (SE) US. Locally, ECWs are synoptically organized by anomalous high pressure and northerly flow. At larger scales, the UM LMP features a zonal dipole in the mid-tropospheric height field over North America, while the NW and SE LMPs each include a zonal wave train extending from the North Pacific across North America into the North Atlantic. The Community Climate System Model version 4 (CCSM4) in general simulates the three ECW patterns quite well and successfully reproduces the observed enhancements in the frequency of their associated LMPs. La Niña and the cool phase of the Pacific Decadal Oscillation (PDO) favor the occurrence of NW ECWs, while the warm PDO phase, low Arctic sea ice extent and high Eurasian snow cover extent (SCE) are associated with elevated SE-ECW frequency. Additionally, high Eurasian SCE is linked to increases in the occurrence likelihood of UM ECWs.

    Factors such as technological advancements, steadily decreasing costs, consumer demand, and state and federal policies are combining to make wind energy the world's fastest growing energy source. State and federal policies are facilitating the growth of the domestic, large-scale wind power market; however, small-scale wind projects (those with a capacity of less than 100 kilowatts[kW]) still face challenges in many states. Net metering, also referred to as net billing, is one particular policy that states are implementing to encourage the use of small renewable energy systems. Net metering allows individual, grid-tied customers who generate electricity using a small renewable energy system to receive credit from their utility for any excess power they generate beyond what they consume. Under most state rules, residential, commercial, and industrial customers are eligible for net metering; however, some states restrict eligibility to particular customer classes. This paper illustrates how net metering programs in certain states vary considerably in terms of how customers are credited for excess power they generate; the type and size of eligible technologies and whether the utility; the state, or some other entity administers the program. This paper focuses on10 particular states where net metering policies are in place. It analyzes how the different versions of these programs affect the use of small-scale wind technologies and whether some versions are more favorable to this technology than others. The choice of citizens in some states to net meter with photovoltaics is also examined.

    There has been an increase in the use of mental health services in a number of industrialized countries over the past two decades with little impact on mental health status of the populations. Few studies, however, have examined recent trends in mental health status in the US. Using data from three large general annual population surveys in the US-the National Health Interview Survey, Behavioral Risk Factor Surveillance System, and National Survey on Drug Use and Health-we examined temporal trends in non-specific psychological distress, depressive episodes and mental health treatment seeking over the 2001-2012 period. Prevalence of past-month significant psychological distress and past-year depressive symptoms changed little over time. However, a larger percentage of participants reported poor mental health for ≥15 days or 30 days in the past month in 2011-2012 (8.7% and 5.7%, respectively) than in 2001-2002 (6.6% and 4.6%). A larger percentage of participants in the later period also reported receiving mental health treatments. Possible changes in mental health status may have been missed due to the limited scope of assessments or the small magnitude of changes. Potential reciprocal influences between service use and mental health status could not be investigated because of cross-sectional data. Despite increasing use of mental health treatments in the US in the first decade of this century, there is no evidence of decrease in prevalence of psychological distress or depression. Poor match between need for treatment and actual treatments received in usual care settings may partly explain the findings. Copyright © 2014 Elsevier B.V. All rights reserved.

    Societal cost-effectiveness analysis and its variants help decision makers achieve an efficient allocation of resources across the set of all possible health interventions. Sometimes, however, decision makers are focused instead on the efficient allocation of resources within a particular intervention program that has already been implemented. This is especially true when the intervention is being delivered at several different sites. An analysis of average cost across program sites may help program officials to maximize the health benefits that can be achieved with limited resources. In this article, the authors present such an analysis, with special attention paid to the possible existence and implications of economies of scale. Focusing on federally sponsored, state-organized cancer detection programs, the authors modeled 19 state programs as productive processes and examined their average costs over a 2- to 5-year period of operation. They considered 3 alternative definitions of output: women served, screens performed, and conditions detected. Average federal costs and average total costs were estimated for each grant period. Multivariate regression analysis was used to help explain the variation in average costs. The average cost estimates were distributed in a skewed pattern with the majority of observations falling close to the median and substantially below the mean. For all measures considered, average cost decreased as output expanded. This inverse relationship between average cost and output level persisted even after controlling for the effects of other predictors, suggesting the possible existence of economies of scale. The potential existence of economies of scale calls into question the assumption of a constant average cost frequently made in economic analyses of proposed public health programs. It also implies that a) differences in output level should be taken into account when comparing operating efficiency across program sites; b) conclusions

    Chinese students are the biggest ethnic group of international students in the United States. This study aims to develop a reliable and valid scale to accurately measure their acculturative stress. A 72-item pool was sent online to Chinese students and a five-factor scale of 32 items was generated by exploratory factor analysis. The five factors included language insufficiency, social isolation, perceived discrimination, academic pressure, and guilt toward family. The Acculturative Stress Scale for Chinese Students demonstrated high reliability and initial validity by predicting depression and life satisfaction. It was the first Chinese scale of acculturative stress developed and validated among a Chinese student sample in the United States. In the future, the scale can be used as a diagnostic tool by mental health professionals and a self-assessment tool by Chinese students. (c) 2016 APA, all rights reserved.

    Increasingly uncertain hydrologic regimes are challenging water systems management worldwide, emphasizing the need of accurate medium- to long-term predictions to timely prompt anticipatory operations. In fact, forecasts are usually skillful over short lead time (from hours to days), but predictability tends to decrease on longer lead times. The forecast lead time might be extended by using climate teleconnection, such as El Nino Southern Oscillation (ENSO). Despite the ENSO teleconnection is well defined in some locations such as Western USA and Australia, there is no consensus on how it can be detected and used in other river basins, particularly in Europe, Africa, and Asia. In this work, we propose the use of the Nino Index Phase Analysis for capturing the state of multiple large-scale climate signals (i.e., ENSO, North Atlantic Oscillation, Pacific Decadal Oscillation, Atlantic Multidecadal Oscillation, Dipole Mode Index). This climate state information is used for distinguishing the different phases of the climate signals and for identifying relevant teleconnections between the observations of Sea Surface Temperature (SST) that mostly influence the local hydrologic conditions. The framework is applied to the Lake Como system, a regulated lake in northern Italy which is mainly operated for flood control and irrigation supply. Preliminary results show high correlations between SST and three to six months ahead precipitation in the Lake Como basin. This forecast represents a valuable information to partially anticipate the summer water availability, ultimately supporting the improvement of the Lake Como operations.

    As large utility-scale solar photovoltaic (PV) and concentrating solar power (CSP) facilities are currently being built and planned for locations in the U.S. with the greatest solar resource potential, an understanding of water use for construction and operations is needed as siting tends to target locations with low natural rainfall and where most existing freshwater is already appropriated. Using methods outlined by the Bureau of Land Management (BLM) to determine water used in designated solar energy zones (SEZs) for construction and operations & maintenance, an estimate of water used over the lifetime at the solar power plant is determined and applied to each watershed in six Southwestern states. Results indicate that that PV systems overall use little water, though construction usage is high compared to O&M water use over the lifetime of the facility. Also noted is a transition being made from wet cooled to dry cooled CSP facilities that will significantly reduce operational water use at these facilities. Using these water use factors, estimates of future water demand for current and planned solar development was made. In efforts to determine where water could be a limiting factor in solar energy development, water availability, cost, and projected future competing demands were mapped for the six Southwestern states. Ten watersheds, 9 in California, and one in New Mexico were identified as being of particular concern because of limited water availability.

  1. History and evaluation of national-scale geochemical data sets for the United States

    Full Text Available Six national-scale, or near national-scale, geochemical data sets for soils or stream sediments exist for the United States. The earliest of these, here termed the ‘Shacklette’ data set, was generated by a U.S. Geological Survey (USGS project conducted from 1961 to 1975. This project used soil collected from a depth of about 20 cm as the sampling medium at 1323 sites throughout the conterminous U.S. The National Uranium Resource Evaluation Hydrogeochemical and Stream Sediment Reconnaissance (NURE-HSSR Program of the U.S. Department of Energy was conducted from 1975 to 1984 and collected either stream sediments, lake sediments, or soils at more than 378,000 sites in both the conterminous U.S. and Alaska. The sampled area represented about 65% of the nation. The Natural Resources Conservation Service (NRCS, from 1978 to 1982, collected samples from multiple soil horizons at sites within the major crop-growing regions of the conterminous U.S. This data set contains analyses of more than 3000 samples. The National Geochemical Survey, a USGS project conducted from 1997 to 2009, used a subset of the NURE-HSSR archival samples as its starting point and then collected primarily stream sediments, with occasional soils, in the parts of the U.S. not covered by the NURE-HSSR Program. This data set contains chemical analyses for more than 70,000 samples. The USGS, in collaboration with the Mexican Geological Survey and the Geological Survey of Canada, initiated soil sampling for the North American Soil Geochemical Landscapes Project in 2007. Sampling of three horizons or depths at more than 4800 sites in the U.S. was completed in 2010, and chemical analyses are currently ongoing. The NRCS initiated a project in the 1990s to analyze the various soil horizons from selected pedons throughout the U.S. This data set currently contains data from more than 1400 sites. This paper (1 discusses each data set in terms of its purpose, sample collection protocols

    Mental health problems are endemic across the globe, and suicide, a strong corollary of poor mental health, is a leading cause of death. Classic psychedelic use may occasion lasting improvements in mental health, but the effects of classic psychedelic use on suicidality are unknown. We evaluated the relationships of classic psychedelic use with psychological distress and suicidality among over 190,000 USA adult respondents pooled from the last five available years of the National Survey on Drug Use and Health (2008-2012) while controlling for a range of covariates. Lifetime classic psychedelic use was associated with a significantly reduced odds of past month psychological distress (weighted odds ratio (OR)=0.81 (0.72-0.91)), past year suicidal thinking (weighted OR=0.86 (0.78-0.94)), past year suicidal planning (weighted OR=0.71 (0.54-0.94)), and past year suicide attempt (weighted OR=0.64 (0.46-0.89)), whereas lifetime illicit use of other drugs was largely associated with an increased likelihood of these outcomes. These findings indicate that classic psychedelics may hold promise in the prevention of suicide, supporting the view that classic psychedelics' most highly restricted legal status should be reconsidered to facilitate scientific study, and suggesting that more extensive clinical research with classic psychedelics is warranted. © The Author(s) 2015.

  3. An analysis of more than 1,400 articles, 900 scales, and 17 years of research: the state of scales in cyberpsychology, behavior, and social networking.

    Cyberpsychology is a recently emergent field that examines the impact of technology upon human cognition and behavior. Given its infancy, authors have rapidly created new measures to gauge their constructs of interest. Unfortunately, few of these authors have had the opportunity to test their scales' psychometric properties and validity. This is concerning, as many theoretical assumptions may be founded upon scales with inadequate attributes. If this were found to be true, then previous findings in cyberpsychology studies would need to be retested, and future research would need to shift its focus to creating psychometrically sound and valid measures. To provide inferences on this concern, the current study examines the article reporting, scale creation, and scale reliabilities of every article published in Cyberpsychology, Behavior, and Social Networking from its inception to July 2014. The final data set encompassed the coding of 1,478 individual articles, including 921 scales, and spanning 17 years. The results demonstrate that the simple survey methodology has become more popular over time. Authors are gradually applying empirically tested scales. However, self-created measures are still the most popular, leading to concerns about the measures' validity. Also, the use of multi-item measures has increased over time, but many articles still fail to report adequate information to assess the reliability of the applied scales. Lastly, the average scale reliability is 0.81, which barely meets standard cutoffs. Overall, these results are not overly concerning, but suggestions are given on methods to improve the reporting of measures, the creation of scales, and the state of cyberpsychology.

    Self-monitoring is the extent to which individuals regulate self-presentation for the sake of desired public appearances. Snyder developed a Self-Monitoring Scale to measure individual differences on this construct. Since the measure could be insensitive to situational influences, it is uncertain whether the short-term self-monitoring elicited by certain social interactions could be examined. The present study explored the factor structures of a state self-monitoring scale which was adapted from 10 items of the Self-Monitoring Scale. Participants took part in an individual interview with an unfamiliar authority, and then completed the State Self-Monitoring Scale. Two samples of adolescents (N=98 and N=95) were tested. Exploratory factor analysis and confirmatory factor analysis using the two samples indicated that the 9-item State Self-Monitoring Scale had two stable factors. There was a statistically significant difference on State Self-monitoring between adolescents with high and low academic achievement, supporting the validity of the scale.

  6. State-of-the-Art in GPU-Based Large-Scale Volume Visualization

    KAUST Repository

    Beyer, Johanna

    2015-05-01

    This survey gives an overview of the current state of the art in GPU techniques for interactive large-scale volume visualization. Modern techniques in this field have brought about a sea change in how interactive visualization and analysis of giga-, tera- and petabytes of volume data can be enabled on GPUs. In addition to combining the parallel processing power of GPUs with out-of-core methods and data streaming, a major enabler for interactivity is making both the computational and the visualization effort proportional to the amount and resolution of data that is actually visible on screen, i.e. \\'output-sensitive\\' algorithms and system designs. This leads to recent output-sensitive approaches that are \\'ray-guided\\', \\'visualization-driven\\' or \\'display-aware\\'. In this survey, we focus on these characteristics and propose a new categorization of GPU-based large-scale volume visualization techniques based on the notions of actual output-resolution visibility and the current working set of volume bricks-the current subset of data that is minimally required to produce an output image of the desired display resolution. Furthermore, we discuss the differences and similarities of different rendering and data traversal strategies in volume rendering by putting them into a common context-the notion of address translation. For our purposes here, we view parallel (distributed) visualization using clusters as an orthogonal set of techniques that we do not discuss in detail but that can be used in conjunction with what we present in this survey. © 2015 The Eurographics Association and John Wiley & Sons Ltd.

    2015-09-01

    Full Text Available Cancer remains a major health problem worldwide. Due to the efficacy of the treatments and the improvements in healthcare systems, however, the number of cancer survivors has increased significantly over the years. Fatigue is one of the consequences of cancer that appears most frequently, causing significant changes in the lives of survivors. Different psychological treatments have been used to reduce fatigue in this patient group. Cognitive-behavioural techniques and mindfulness therapies are the ones that have the most data supporting their effectiveness, ahead of psycho-educational type interventions. The majority of studies, however, have been conducted with breast cancer survivors, and it would be desirable to test the effectiveness of these techniques with a greater variability of cancer types.

    The transition into retirement is an important life phase that presents significant challenges in respect to well-being, lifestyle, and consumption choices. This article examines the consumption context of housing after retirement, in particular for the low-resourced cohort of single baby boomer women. Utilizing an extended Theory of Planned Behavior model, we examine the relationship between intention and actual behavior, in this case financial advice seeking, as an important component of the psychological preparedness of single female baby boomer women. Our analysis showed both Australian and UK single baby boomer women display different behaviors in terms of seeking advice and their mental preparedness to adjust to a change in their living arrangements. The findings are discussed in terms of their implications for policy and further research.

  9. The Study of Faculty Productivity through Confirmatory Factor Analysis: the case of Psychology in United States of America

    Directory of Open Access Journals (Sweden)

    MARÍA CARIDAD GARCÍA-CEPERO

    2010-03-01

    Full Text Available The article proposes the use of Confirmatory Factor Analysis techniques as a new approach to the measurement problem of faculty productivity. For this purpose, the author uses an analysis of scholarly productivity with data of 513 professors in the field of psychology in North America, between 1997 and 1998. Based on this analysis it is possible to identify three latent variables that describe the productivity of the sample: one factor that captures theinflation of all the observed variables, one factor that measures individual productivity and a factor that measures the joint productivity of faculty members. The findings suggest the need of novel approaches to policies for measurement and support of faculty productivity. These policies should be oriented not only to increase the productivity rates but also to decrease the probability of inflation.

    The Thomas-Fermi approach to galaxy structure determines self-consistently and non-linearly the gravitational potential of the fermionic warm dark matter (WDM) particles given their quantum distribution function f(E). This semiclassical framework accounts for the quantum nature and high number of DM particles, properly describing gravitational bounded and quantum macroscopic systems as neutron stars, white dwarfs and WDM galaxies. We express the main galaxy magnitudes as the halo radius r{sub h}, mass M{sub h}, velocity dispersion and phase space density in terms of the surface density which is important to confront to observations. From these expressions we derive the general equation of state for galaxies, i.e., the relation between pressure and density, and provide its analytic expression. Two regimes clearly show up: (1) Large diluted galaxies for M{sub h} >or similar 2.3 x 10{sup 6} M {sub CircleDot} and effective temperatures T{sub 0} > 0.017 K described by the classical self-gravitating WDM Boltzman gas with a space-dependent perfect gas equation of state, and (2) Compact dwarf galaxies for 1.6 x 10{sup 6} M {sub CircleDot} >or similar M{sub h} >or similar M{sub h,min} ≅ 3.10 x 10{sup 4} (2 keV/m){sup (16)/(5)} M {sub CircleDot}, T{sub 0} < 0.011 K described by the quantum fermionic WDM regime with a steeper equation of state close to the degenerate state. In particular, the T{sub 0} = 0 degenerate or extreme quantum limit yields the most compact and smallest galaxy. In the diluted regime, the halo radius r{sub h}, the squared velocity v{sup 2}(r{sub h}) and the temperature T{sub 0} turn to exhibit square-root of M{sub h} scaling laws. The normalized density profiles ρ(r)/ρ(0) and the normalized velocity profiles v{sup 2}(r)/v{sup 2}(0) are universal functions of r/r{sub h} reflecting the WDM perfect gas behavior in this regime. These theoretical results contrasted to robust and independent sets of galaxy data remarkably reproduce the observations. For

    2017-04-01

    Large-scale forest restoration is a cornerstone of Brazil’s new Forest Code and a key element in its National Determined Contribution (NDC) to emissions reduction. But the path to this target remains unclear due to a lack of information on its economics and implementation challenges. Here, we begin to fill this gap by developing a spatially-explicit model for Minas Gerais state that estimates the costs and benefits of native vegetation regeneration under different restoration approaches. Our results show that 36% (0.7 million ha) of the Forest Code debt in Minas Gerais can be restored using only passive restoration, at a cost of US 175 ± 47 million. Adding low-cost assisted natural regeneration would increase that number to 75% (1.5 million ha) at a cost of US 776 ± 137 million over a 20 yr period. This would result in a potential sequestration of 284 MtCO2e. However, including the intensive planting methods needed to restore the remaining 25% of highly degraded areas—to fully solve the Forest Code debt and result in a potential sequestration of 345 MtCO2e—would more than double the costs to US 1.7 ± 0.3 billion. Our results emphasize the need to implement regional policies that take advantage of the natural regeneration potential as well as prioritize the restoration of areas key to ecosystem services.

    Full Text Available Objective: The aim of our study is to examine cognitive performance after mild stroke via Mini Mental State Examination (MMSE and Montreal cognitive assessment scale (MoCA and to compare the results.Material and methods: We examined 54 patients with mild stroke (aged 52 to 72 (mean 63.17, SD 5.96; 34 males and 20 females and 54 controls, adjusted by age, sex and education level. All subjects were tested via MMSE (Bulgarian version and MoCa (Bulgarian version. Data was collected in the single step model at the 90th day after stroke incident for patients and at the day of obtaining informed consent for controls. Results: Patients have poorer performance on both MMSE and MoCa than controls. MoCa has comparatively good discriminative validity and sensitivity.Conclusions: Although MMSE is one of the classical screening tools for cognitive impairment widely used in Bulgaria, other screening tools should not be ignored. On the basis of our results, MoCa is also a good screening instrument, especially for poststroke cognitive impairment.

  14. Vibration Mitigation without Dissipative Devices: First Large-Scale Testing of a State Switched Inducer

    Directory of Open Access Journals (Sweden)

    Daniel Tirelli

    2014-01-01

    Full Text Available A new passive device for mitigating cable vibrations is proposed and its efficiency is assessed on 45-meter long taut cables through a series of free and forced vibration tests. It consists of a unilateral spring attached perpendicularly to the cable near the anchorage. Because of its ability to change the cable dynamic behaviour through intermittent activation, the device has been called state switched inducer (SSI. The cable behaviour is shown to be deeply modified by the SSI: the forced vibration response is anharmonicc and substantially reduced in amplitude whereas the free vibration decay is largely sped up through a beating phenomenon. The vibration mitigation effect is mainly due to the activation and coupling of various vibration modes, as evidenced in the response spectra of the equipped cable. This first large-scale experimental campaign shows that the SSI outperforms classical passive devices, thus paving the way to a new kind of low-cost vibration mitigation systems which do not rely on dissipation.

    To examine the association between stroke and migraine in an epidemiological study. DATA SOURCES AND DESIGN: The National Health and Nutrition Examination Survey baseline and first follow-up data were used to investigate cross-sectional and longitudinal associations between headache/migraine and stroke. Study participants from a national probability sample of the civilian noninstitutionalized population of the United States. Self-reported physician diagnosis of stroke. After controlling for established risk factors for stroke (hypertension, diabetes, heart disease, and gender), both migraine and severe nonspecific headache were associated with a significantly increased risk for stroke reported at follow-up. The risk for stroke associated with migraine decreased as the age at stroke increased. Our results strengthen previous evidence regarding a nonrandom association of both headache and migraine with stroke, particularly among young women. To our knowledge, this is the first systematic examination in a large-scale prospective epidemiological study of men and women with sufficient statistical power to test the association between migraine and stroke in women. Severe headache and migraine should be considered as risk factors for the development of stroke, particularly in the absence of other well-established stroke risk factors. Further investigation is required to identify the putative mechanisms underlying comorbidity of migraine and stroke.

    The emissions of volatile organic compounds (VOC), CH4, N2O and NH3 during the solid state fermentation process of some selected wastes to obtain different enzymes have been determined at pilot scale. Orange peel+compost (OP), hair wastes+raw sludge (HW) and winterization residue+raw sludge (WR) have been processed in duplicate in 50 L reactors to provide emission factors and to identify the different VOC families present in exhaust gaseous emissions. Ammonia emission from HW fermentation (3.2±0.5 kg Mg(-1) dry matter) and VOC emission during OP processes (18±6 kg Mg(-1) dry matter) should be considered in an industrial application of these processes. Terpenes have been the most emitted VOC family during all the processes although the emission of sulphide molecules during HW SSF is notable. The most emitted compound was dimethyl disulfide in HW and WR processes, and limonene in the SSF of OP. Copyright © 2014 Elsevier Ltd. All rights reserved.

  17. Equation of state with scale-invariant hidden local symmetry and gravitational waves

    Full Text Available The equation of state (EoS for the effective theory proposed recently in the frame work of the scale-invariant hidden local symmetry is discussed briefly. The EoS is found to be relatively stiffer at lower density and but relatively softer at higher density. The particular features of EoS on the gravitational waves are discussed. A relatively stiffer EoS for the neutron stars with the lower density induces a larger deviation of the gravitational wave form from the point-particle-approximation. On the other hand, a relatively softer EoS for the merger remnant of the higher density inside might invoke a possibility of the immediate formation of a black hole for short gamma ray bursts or the appearance of the higher peak frequency for gravitational waves from remnant oscillations. It is anticipated that this particular features could be probed in detail by the detections of gravitational waves from the binary neutron star mergers.

    We aimed to discriminate individuals with depressive state from individuals with cognitive impairment among community-dwelling people using the subjective memory complaints (SMC) scale. The study group consisted of 289 volunteers (over 60 years old; 104 males and 185 females). Participants' SMCs were assessed using the SMC scale. The Japanese version of the Center for Epidemiologic Studies for Depression scale and the Mini-Mental State Examination were administered. Participants whose Center for Epidemiologic Studies for Depression scores were 16 or higher were defined as the depressive group and participants whose Mini-Mental State Examination scores were less than 24 were defined as the cognitive impairment group. Exploratory factor analysis was performed to identify the factor structure of the items of the SMC scale. A multiple logistic regression analysis of the association between depressive state and cognitive impairment and the score of each factor was performed. In the final factor analysis model, six items of the SMC scale remained, and a two-factor structure was adequate. Factor 1 included the items 8, 9, and 10 about thought or the ability to think; thus, Factor 1 was defined as "thought disturbance factor". Factor 2 included the items 1, 2, and 4 about memory or forgetfulness; thus, Factor 2 was defined as "memory disturbance factor". In the multiple logistic regression analysis, Factor 1 was significantly associated with depressive state and Factor 2 was significantly associated with cognitive impairment. For individuals with SMCs, we might be able to discriminate depressive state or depression from cognitive impairment or dementia through a detailed investigation using the SMC scale.

    In Hungary one can mostly find references to the psychological processes of politics in the writings of publicists, public opinion pollsters, philosophers, social psychologists, and political analysts. It would be still important if not only legal scientists focusing on political institutions or sociologist-politologists concentrating on social structures could analyse the psychological aspects of political processes; but one could also do so through the application of the methods of political psychology. The authors review the history of political psychology, its position vis-à-vis other fields of science and the essential interfaces through which this field of science, which is still to be discovered in Hungary, connects to other social sciences. As far as its methodology comprising psycho-biographical analyses, questionnaire-based queries, cognitive mapping of interviews and statements are concerned, it is identical with the psychiatric tools of medical sciences. In the next part of this paper, the focus is shifted to the essence and contents of political psychology. Group dynamics properties, voters' attitudes, leaders' personalities and the behavioural patterns demonstrated by them in different political situations, authoritativeness, games, and charisma are all essential components of political psychology, which mostly analyses psychological-psychiatric processes and also involves medical sciences by relying on cognitive and behavioural sciences. This paper describes political psychology, which is basically part of social sciences, still, being an interdisciplinary science, has several ties to medical sciences through psychological and psychiatric aspects.

    The knowledge of the clinical features of the mixed states and of the symptoms of the "mixity" of mood disorders is crucial: to mis-diagnose or mis-treat patients with these symptoms may increase the suicide risk and make worse the evolution of mood disorders. The rating scale "G.T. MSRS" has been designed to improve the clinical effectiveness of both psychiatrists and GPs by enabling them to make an early "general" diagnosis of mixed states. This study presents some cases in which the "G.T. MSRS" scale has been used, in order to demonstrate its usefullness.

  1. Identity of psychology, identity and psychology

    Directory of Open Access Journals (Sweden)

    Mirjana Nastran Ule

    2003-09-01

    Full Text Available The article deals with epistemic issues of modern psychology with the starting hypothesis being that scientific psychology must satisfy three main interests: scientific, practical and emancipatory interest. Particularly important is the emancipatory interest, which is based on the social reflection of scientific work and conclusions. Psychological knowledge involves not only neutral descriptions of facts, but also implicit rules, expectations regarding values or norms, and criticism of undesirable behavior. The traditional psychological model attempts to satisfy the scientific interest and partly practical interest, while avoiding emancipatory interest. But I believe modern socio-historical models of psychology to be significant precisely owing to the inclusion of emancipatory interest. The difference between these two models of psychology is most obvious in their perception of identity i.e. individuality. Conventional perceptions follow the logic of "possessive individualism" in which the individual is seen as an autonomous bearer and owner of his/her psychological states and processes. The conventional model of identity supports the modernist concept of the individual as being focused on his/her self or personal identity. Socio-historical models, on the other hand, see the individual as a being embedded in social relations and social interactions, and one who builds and expresses his/her individuality through the reflection on social interactions, discursive practices, and response to the hierarchy of power and social mechanisms of control. According to this model, identity evolves through a series of social constructions which are embodied in the individual and represent him/her in society. Identity thus becomes a notion that combines individuality and social context, subjectivation and objectivation of the individual, and historical and biographical time.

  2. Update on Psychological Trauma, Other Severe Adverse Experiences and Eating Disorders: State of the Research and Future Research Directions.

    Trottier, Kathryn; MacDonald, Danielle E

    2017-08-01

    This paper provides an updated review of the literature on the relationship between psychological trauma exposure, other severe adverse experiences, and eating disorders. Trauma exposure and other severe adverse experiences (e.g., emotional abuse) in both childhood and adulthood are associated with eating disorders. The relationship between traumatic and other adverse experiences and eating disorders appears to be mediated by emotional and behavioral dysregulation, as well as by cognitive factors such as self-criticism. Biological vulnerabilities may also be relevant to this relationship. Overall, the literature is limited by predominantly cross-sectional designs. There is clear evidence of a correlational relationship between trauma exposure and other severe adverse events, and eating disorders. Both risk and maintenance factor hypotheses have been put forth; however, prospective research testing these hypotheses remains limited. Future research should use prospective designs and focus on trauma-related symptoms (rather than trauma exposure) in order to advance research on risk and maintaining factors for eating disorders and inform treatment directions.

    The goal of this study was to assess for the main sources of occupational stress, as well as self-reported symptoms of distress and post-traumatic stress disorder among U.S. Air Force (USAF) Distributed Common Ground System (DCGS) intelligence exploitation and support personnel. DCGS intelligence operators (n=1091) and nonintelligence personnel (n = 447) assigned to a USAF Intelligence, Surveillance, and Reconnaissance Wing responded to the web-based survey. The overall survey response rate was 31%. Study results revealed the most problematic stressors among DCGS intelligence personnel included high workload, low manning, as well as organizational leadership and shift work issues. Results also revealed 14.35% of DCGS intelligence operators' self-reported high levels of psychological distress (twice the rate of DCGS nonintelligence support personnel). Furthermore, 2.0% to 2.5% self-reported high levels of post-traumatic stress disorder symptoms, with no significant difference between groups. The implications of these findings are discussed along with recommendations for USAF medical and mental health providers, as well as operational leadership.

It uses up to date research evidence, established theory and a variety of activities that help the student consider and understand academic and professional aspects of this particular academic discipline. PURPOSE The book aims to provide the undergraduate psychology student with a structured introduction to the subject area and an insight into the theoretical evidence and practical suggestions that underpin what a Sport and Exercise psychologist does. The book also aims to support one term or one semester courses in Sport and Exercise Psychology. It is also appropriate for Masters level courses. FEATURES The book begins with a chapter on applied sports psychology to give the reader an insight into the domain of sport psychology, providing an overview of the techniques that could be used. The next three chapters focus on mood, anxiety and self confidence, which influence performance. This leads on to four chapters that focus on managing psychological states. There is also a chapter on leadership which interestingly includes leadership development in coaches and in athletes. Two chapters focus on the effects of exercise on psychological states, providing a balance between the benefits and potential drawbacks. The final chapter examines the issue of placebo effects. Throughout each chapter there are useful activities than can help the reader's understanding of practical and theoretical issues. These also have practical implications for the work of a Sport and Exercise Psychologist. Key ethical issues are raised on a regular basis throughout the text. The book offers an excellent blend of theory and practical suggestions which are critically discussed thus giving valuable insights regarding the research process and applied practice which is often lacking in the more well known standard textbooks for Sport

  8. Mother and Infant Talk about Mental States: Systemic Emergence of Psychological Lexicon and Theory of Mind Understanding

    Science.gov (United States)

    Rollo, D.; Buttiglieri, F.

    In recent years, a number of studies that have examined how social experiences are related to children's theory of mind development, have found that: (1) the frequency of mothers' mental state utterances used in mother-child picture-book reading, is correlated with children's theory of mind abilities; (2) mothers' use of cognitive terms is related more strongly to children's theory of mind performances than the mothers' references to other mental states, such as desires or emotions (Adrian, Clemente, Villanueva, Rieffe, 2005; Ruffman, Slade, Crowe, 2002; Taumoepeau, Ruffman, 2006; Dunn, 2002). Despite the evidence for the role of mothers' language, there is disagreement over how exactly it improves children's theory of mind development. In short, mentalistic comments contain distinctive words, grammatical constructions and pragmatic features. The question is, however, which factor is critical (de Rosnay, Pons, Harris, Morrell, 2004). The present study addresses this issue and focuses on relationship between mothers' mental state terms and children's performances in theory of mind tasks (emotion understanding and false belief tasks). Mothers were asked to read some pictures to 10 children between 3;0 and 5;0. Among the different mental state references (perceptual, emotional, volitional, cognitive, moral and communicative), it was found that the frequency and variety of mothers' mental state words were significantly associated with children's mental lexicon. In addition, emotional terms correlated positively with children's false belief performance. Kind of emotional words that are used by the mothers with reference to the Italian language will be discussed.

  10. Information processing in micro and meso-scale neural circuits during normal and disease states

    Science.gov (United States)

    Luongo, Francisco

    Neural computation can occur at multiple spatial and temporal timescales. The sum total of all of these processes is to guide optimal behaviors within the context of the constraints imposed by the physical world. How the circuits of the brain achieves this goal represents a central question in systems neuroscience. Here I explore the many ways in which the circuits of the brain can process information at both the micro and meso scale. Understanding the way information is represented and processed in the brain could shed light on the neuropathology underlying complex neuropsychiatric diseases such as autism and schizophrenia. Chapter 2 establishes an experimental paradigm for assaying patterns of microcircuit activity and examines the role of dopaminergic modulation on prefrontal microcircuits. We find that dopamine type 2 (D2) receptor activation results in an increase in spontaneous activity while dopamine type 1 (D1) activation does not. Chapter 3 of this dissertation presents a study that illustrates how cholingergic activation normally produces what has been suggested as a neural substrate of attention; pairwise decorrelation in microcircuit activity. This study also shows that in two etiologicall distinct mouse models of autism, FMR1 knockout mice and Valproic Acid exposed mice, this ability to decorrelate in the presence of cholinergic activation is lost. This represents a putative microcircuit level biomarker of autism. Chapter 4 examines the structure/function relationship within the prefrontal microcircuit. Spontaneous activity in prefrontal microcircuits is shown to be organized according to a small world architecture. Interestingly, this architecture is important for one concrete function of neuronal microcircuits; the ability to produce temporally stereotyped patterns of activation. In the final chapter, we identify subnetworks in chronic intracranial electrocorticographic (ECoG) recordings using pairwise electrode coherence and dimensionality reduction

    Mindfulness is an increasingly popular construct with promise in enhancing multiple positive health outcomes. Physical activity is an important behavior for enhancing overall health, but no Spanish language scale exists to test how mindfulness during physical activity may facilitate physical activity motivation or behavior. This study examined the validity of a Spanish adaption of a new scale, the State Mindfulness Scale for Physical Activity, to assess mindfulness during a specific experience of physical activity. Spanish youths (N = 502) completed a cross-sectional survey of state mindfulness during physical activity and physical activity motivation regulations based on Self-Determination Theory. A high-order model fit the data well and supports the use of one general state mindfulness factor or the use of separate subscales of mindfulness of mental (e.g., thoughts, emotions) and body (physical movement, muscles) aspects of the experience. Internal consistency reliability was good for the general scale and both sub-scales. The pattern of correlations with motivation regulations provides further support for construct validity with significant and positive correlations with self-determined forms of motivation and significant and negative correlations with external regulation and amotivation. Initial validity evidence is promising for the use of the adapted measure.

    Jakob, Christian [Monash Univ., Melbourne, VIC (Australia)

    2015-02-26

    This report summarises an investigation into the relationship of tropical thunderstorms to the atmospheric conditions they are embedded in. The study is based on the use of radar observations at the Atmospheric Radiation Measurement site in Darwin run under the auspices of the DOE Atmospheric Systems Research program. Linking the larger scales of the atmosphere with the smaller scales of thunderstorms is crucial for the development of the representation of thunderstorms in weather and climate models, which is carried out by a process termed parametrisation. Through the analysis of radar and wind profiler observations the project made several fundamental discoveries about tropical storms and quantified the relationship of the occurrence and intensity of these storms to the large-scale atmosphere. We were able to show that the rainfall averaged over an area the size of a typical climate model grid-box is largely controlled by the number of storms in the area, and less so by the storm intensity. This allows us to completely rethink the way we represent such storms in climate models. We also found that storms occur in three distinct categories based on their depth and that the transition between these categories is strongly related to the larger scale dynamical features of the atmosphere more so than its thermodynamic state. Finally, we used our observational findings to test and refine a new approach to cumulus parametrisation which relies on the stochastic modelling of the area covered by different convective cloud types.

    This study aimed to explore the levels of John Henryism (JH) active coping and its association with acculturation status and psychological health (specifically perceived stress, acculturative stress, anxiety, and depression) in Korean immigrants to the United States. In 102 Korean immigrants, JH active coping was measured by the JH Scale; acculturation by the Bidimensional Acculturation Scale; perceived stress by the Perceived Stress Scale; acculturative stress by the Social, Attitudinal, Familial, and Environmental Scale; anxiety by the State Anxiety Subscale of the Spielberger State-Trait Anxiety Inventory; and depression by the Center for Epidemiological Studies Depression Scale. The levels of JH active coping in this sample of Korean immigrants appear to be lower than the levels reported in other racial groups. Independent of demographic factors, JH active coping was a significant predictor of higher acculturation status and better psychological health as indicated by lower levels of perceived stress, acculturative stress, anxiety, and depressive symptoms.

    Other than the nine Solar Energy Generation Systems (“SEGS”) parabolic trough projects built in the 1980s, virtually no large-scale or “utility-scale” solar projects – defined here to include any groundmounted photovoltaic (“PV”), concentrating photovoltaic (“CPV”), or concentrating solar thermal power (“CSP”) project larger than 5 MWAC – existed in the United States prior to 2007. By 2012 – just five years later – utility-scale had become the largest sector of the overall PV market in the United States, a distinction that was repeated in both 2013 and 2014 and that is expected to continue for at least the next few years. Over this same short period, CSP also experienced a bit of a renaissance in the United States, with a number of large new parabolic trough and power tower systems – some including thermal storage – achieving commercial operation. With this critical mass of new utility-scale projects now online and in some cases having operated for a number of years (generating not only electricity, but also empirical data that can be mined), the rapidly growing utility-scale sector is ripe for analysis. This report, the third edition in an ongoing annual series, meets this need through in-depth, annually updated, data-driven analysis of not just installed project costs or prices – i.e., the traditional realm of solar economics analyses – but also operating costs, capacity factors, and power purchase agreement (“PPA”) prices from a large sample of utility-scale solar projects in the United States. Given its current dominance in the market, utility-scale PV also dominates much of this report, though data from CPV and CSP projects are presented where appropriate.

Psychological adaptations of foreign students were examined within the framework of Berry’s (1997 theory of acculturation. The relational study model, one of the general study types, was used in the study. The population of the study consisted of foreign students who are studying at a state university. Since the study aims to reach the whole population, no sample was chosen for the study. The total number of foreign students was 146 in the 2014-2015 academic year. Psychological adaptations of the students were examined with the variables of age, acculturation attitudes, perceived social support, cultural distance, self-efficacy and duration of stay in Turkey. The quantitative data were analyzed via the SPSS 21 package software. The findings of the study showed that the answers that foreign students have given to the life satisfaction scale are at the level of “slightly agree” in both genders. The answers that they have given to the general health scale about how their health is now and has been recently in general are at the level of “less than usual”. The most important variable that predicts the psychological adaptations of students is acculturation attitudes. Among the acculturation attitudes, the students preferred the integration attitude. According to the results of the classification by geographical region, there are similarities in the categories of religious beliefs, family life, customs, world-views, social activities and standards of living of the foreign students. However, there are differences in the categories of clothing, mode of communication, values, and

    The advances in computer science and the availability of new detailed data-sets have led to a growing number of distributed hydrological models applied to finer and finer grid resolutions for larger and larger catchment areas. It was argued, however, that this trend does not necessarily guarantee better understanding of the hydrological processes or it is even not necessary for specific modelling applications. In the present study, this topic is further discussed in relation to the soil spatial heterogeneity and its effect on simulated hydrological state and fluxes. To this end, three methods are developed and used for the characterization of the soil heterogeneity at different spatial scales. The methods are applied at the soil map of the upper Neckar catchment (Germany), as example. The different soil realizations are assessed regarding their impact on simulated state and fluxes using the distributed hydrological model mHM. The results are analysed by aggregating the model outputs at different spatial scales based on the Representative Elementary Scale concept (RES) proposed by Refsgaard et al. (2016). The analysis is further extended in the present study by aggregating the model output also at different temporal scales. The results show that small scale soil variabilities are not relevant when the integrated hydrological responses are considered e.g., simulated streamflow or average soil moisture over sub-catchments. On the contrary, these small scale soil variabilities strongly affect locally simulated states and fluxes i.e., soil moisture and evapotranspiration simulated at the grid resolution. A clear trade-off is also detected by aggregating the model output by spatial and temporal scales. Despite the scale at which the soil variabilities are (or are not) relevant is not universal, the RES concept provides a simple and effective framework to quantify the predictive capability of distributed models and to identify the need for further model improvements e

    Educational measures of anxiety focus heavily on students' experiences with tests yet overlook other assessment contexts. In this research, two brief multiscale questionnaires were developed and validated to measure trait evaluation anxiety (MTEA-12) and state evaluation anxiety (MSEA-12) for use in various assessment contexts in non-clinical, educational settings. The research included a cross-sectional analysis of self-report data using authentic assessment settings in which evaluation anxiety was measured. Instruments were tested using a validation sample of 241 first-year university students in New Zealand. Scale development included component structures for state and trait scales based on existing theoretical frameworks. Analyses using confirmatory factor analysis and descriptive statistics indicate that the scales are reliable and structurally valid. Multivariate general linear modeling using subscales from the MTEA-12, MSEA-12, and student grades suggest adequate criterion-related validity. Initial predictive validity in which one relevant MTEA-12 factor explained between 21% and 54% of the variance in three MSEA-12 factors. Results document MTEA-12 and MSEA-12 as reliable measures of trait and state dimensions of evaluation anxiety for test and writing contexts. Initial estimates suggest the scales as having promising validity, and recommendations for further validation are outlined.

    The feasibility, validity and reliability of the Time Trade-Off (TTO) and Visual Analogue Scale (VAS) methods in obtaining preference values for health states were compared in a random sample of the Spanish population (n = 294). Respondents valued 43 EuroQol-5D health states in face-to-face interviews. Convergent validity was assessed by examining the relationship between values, and the effect of sociodemographic and health variables on values was used as a means of assessing construct validity. Test-retest reliability was analysed in a subgroup of 50 respondents, using the intraclass correlation coefficient (ICC) and generalisability theory. Rates of non-response and missing data were low on both methods, though the VAS took considerably less time to administer. VAS and TTO values correlated highly (r = 0.92), though there were differences in the ordering of health states between methods, and in the number of health states rated worse than death. VAS values were compressed into a considerably smaller valuation space than TTO values. Respondents in higher educational categories assigned higher TTO values to 12 health states. Mean ICCs (95% CI) at individual level were 0.90 (0.88-0.92) and 0.84 (0.81-0.87) for the VAS and TTO, respectively. Generalisability analysis showed variance due to time to be 0 for both methods. In conclusion, the VAS was more feasible and slightly more reliable than the TTO, whilst doubt can be cast on the degree of convergent validity existing between the two methods. The compression of VAS values means that the TTO is likely to discriminate better between health states, and it may have greater construct validity if results from larger samples confirm that there are genuine differences between sociodemographic subgroups.

    2007-08-01

    This report examined ethical violations as grounds for membership expulsions made by the major counseling, psychology, and social work organizations in the United States over a 10-yr. period. Data indicated that the rates of expulsions stayed steady or declined, were disproportional across organizations, and that organizational sanctioning may be even more rigid than that of state boards. In addition, not all organizations followed procedures in a consistent manner when reporting or processing cases. The most common reason for expulsion was for violations under the category of dual relationships, particularly those of a sexual nature. Further research is needed to show how the variations of membership types, the profiles of the offenders, or the potential biases of the committees' judges weigh in on the issued sanctions, particularly those of ambiguous nature (e.g., nonsexual violations). It is also recommended that the expulsion data be easily available to all, and that it be reported systemically for the analysis of trends and for the overall accountability of ethics committees.

    The goal of this study is to repeat a survey administered in 2010 to assess for changes in mental health among United States Air Force aircrew operating Predator/Reaper remotely piloted aircraft, also commonly referred to as "drones." Participants were assessed for self-reported sources of occupational stress, levels of clinical distress using the Outcome Questionnaire-45.2, and symptoms of post-traumatic stress disorder (PTSD) using the PTSD Checklist-Military Version. A total of 1,094 aircrew responded to the web-based survey composed of the commercially available standardized instruments mentioned above. The survey also contained nonstandardized items asking participants to report the main sources of their occupational stress, as well as questions addressing demographics and work-related characteristics. The estimated response rate to the survey was 49%. Study results reveal the most problematic self-reported stressors are operational: low manning, extra duties/administrative tasks, rotating shift work, and long hours. The results also reveal 10.72% of operators self-reported experiencing high levels of distress and 1.57% reported high levels of PTSD symptomology. The results are lower than findings from the 2010 survey and from soldiers returning from Iraq and Afghanistan. Implications of the study and recommendations for United States Air Force line leadership and mental health providers are discussed.

    Full Text Available Abstract Background It is well established that intimate male partner violence (IPV has a high impact on women's mental health. It is necessary to further investigate this impact longitudinally to assess the factors that contribute to its recovery or deterioration. The objective of this study was to assess the course of depressive, anxiety and post-traumatic stress disorder (PTSD symptoms and suicidal behavior over a three-year follow-up in female victims of IPV. Methods Women (n = 91 who participated in our previous cross-sectional study, and who had been either physically/psychologically (n = 33 or psychologically abused (n = 23 by their male partners, were evaluated three years later. A nonabused control group of women (n = 35 was included for comparison. Information about mental health status and lifestyle variables was obtained through face-to-face structured interviews. Results Results of the follow-up study indicated that while women exposed to physical/psychological IPV recovered their mental health status with a significant decrease in depressive, anxiety and PTSD symptoms, no recovery occurred in women exposed to psychological IPV alone. The evolution of IPV was also different: while it continued across both time points in 65.21% of psychologically abused women, it continued in only 12.12% of physically/psychologically abused women while it was reduced to psychological IPV in 51.5%. Hierarchical multiple regression analyses indicated that cessation of physical IPV and perceived social support contributed to mental health recovery, while a high perception of lifetime events predicted the continuation of PTSD symptoms. Conclusion This study shows that the pattern of mental health recovery depends on the type of IPV that the women had been exposed to. While those experiencing physical/psychological IPV have a higher likelihood of undergoing a cessation or reduction of IPV over time and, therefore, could recover, women exposed to

    Contemporary psychology is experiencing tremendous growth in neuroscience, and there is every indication that it will continue to gain in popularity notwithstanding the scarcity of academic positions for newly minted Ph.Ds. Despite the general perception that brain correlates "explain" or "cause" the mind and behavior, these correlates have not yet proven useful in understanding psychological processes, although they offer the possibility of early identification of some disorders. Other recent developments in psychology include increased emphasis on applications and more global representation among researchers and participants. In thinking about the way we want psychology to evolve, psychologists need to pay more than lip service to the idea that complex questions in psychology require multiple levels of analysis with contributions from biological (brain, hormones, and genetics), individual differences and social and cultural perspectives. Early career psychologists who can attain a breadth of knowledge will be well-positioned for a team approach to psychological inquiry. Finally, I offer the belief that an emphasis on enhancing critical thinking skills at all levels of education offers the best hope for the future.

    Asian American women have not benefited from the decline in breast cancer mortality and have lower rates of mammography use. Understanding mammography behaviors among these Asian American women requires culturally specific measures. Champion's belief scale was translated into Thai and cultural items were added. The Thai breast cancer belief scale (TBCBS), the Suinn-Lew self-identification acculturation, and the Asian values scale-revised were administered to 250 Thai immigrants. The TBCBS was tested for face validity, construct validity, and internal consistency. Factor analysis reflected the 4 constructs of the health belief model and accounted for 45.8% of the variance. Cronbach's alpha ranged from .77 to .90. Modest correlations were observed between TBCBS subscales and acculturation scales. Results indicate that the TBCBS measures breast cancer beliefs among Thai immigrant population.

    In a well-functioning and sustainable national energy sector, each of its elements should function with maximum efficiency. To ensure maximum efficiency and study possible improvement of the sector, a scaling-up framework is presented in this work. The scaling-up framework means that the starting point is a CHP unit and its operation, the next step of aggregation is in a district heating network, followed by a municipal energy plan and finally leading to a low carbon strategy. In this framework the authors argue, that the successful, innovative practices developed and tested at the lower level of aggregation can be then transferred to the upper levels of aggregation, thus leading to a scaling-up effect of innovative practices. The work summarizes 12 methodologies used in the energy sector, by dividing these methodologies among the levels of aggregation in a scaling-up framework.

    The screening for anxiety in obstetric settings has been challenging due to time and knowledge constraints. Brief, valid, and reliable instruments can provide health care professionals with a quick and easy method to assess anxiety. Three six-item forms of the State Anxiety Inventory scale have been constructed. The purpose of this study was to evaluate and compare the psychometric properties of these short versions in the perinatal period. Data were drawn from a longitudinal pregnancy cohort in Alberta, Canada. Internal consistency of the shortened versions was assessed. Confirmatory factor analysis was conducted to estimate and compare indicators of fit during pregnancy and at 4 and 12 months postpartum. All shortened scales demonstrated high internal consistency and reliability, with alphas ranging from 0.81 to 0.85. All fit indices were greater than 0.93, implying a good fit between each model and our data. In the model comparisons, the Marteau and Bekker scale provided a more robust fit to data obtained during pregnancy and the early postpartum period. At 12 months postpartum, the Chlan et al. form demonstrated the best fit of the three versions. The shortened scales appear to have acceptable psychometric properties. Brief scales have the potential to provide an economical means of assessing perinatal anxiety and can be considered as equivalent alternatives to the full-scale version.

  9. Detectable states, cycle fluxes, and motility scaling of molecular motor kinesin: An integrative kinetic graph theory analysis

    Ren, Jie

    2017-12-01

    The process by which a kinesin motor couples its ATPase activity with concerted mechanical hand-over-hand steps is a foremost topic of molecular motor physics. Two major routes toward elucidating kinesin mechanisms are the motility performance characterization of velocity and run length, and single-molecular state detection experiments. However, these two sets of experimental approaches are largely uncoupled to date. Here, we introduce an integrative motility state analysis based on a theorized kinetic graph theory for kinesin, which, on one hand, is validated by a wealth of accumulated motility data, and, on the other hand, allows for rigorous quantification of state occurrences and chemomechanical cycling probabilities. An interesting linear scaling for kinesin motility performance across species is discussed as well. An integrative kinetic graph theory analysis provides a powerful tool to bridge motility and state characterization experiments, so as to forge a unified effort for the elucidation of the working mechanisms of molecular motors.

  11. Effects of geomagnetic activity variations on the physiological and psychological state of functionally healthy humans: Some results of Azerbaijani studies

    Babayev, Elchin S.; Allahverdiyeva, Aysel A.

    There are collaborative and cross-disciplinary space weather studies in the Azerbaijan National Academy of Sciences conducted with purposes of revealing possible effects of solar, geomagnetic and cosmic ray variability on certain technological, biological and ecological systems. This paper describes some results of the experimental studies of influence of the periodical and aperiodical changes of geomagnetic activity upon human brain, human health and psycho-emotional state. It also covers the conclusions of studies on influence of violent solar events and severe geomagnetic storms of the solar cycle 23 on the mentioned systems in middle-latitude location. It is experimentally established that weak and moderate geomagnetic storms do not cause significant changes in the brain's bioelectrical activity and exert only stimulating influence while severe disturbances of geomagnetic conditions cause negative influence, seriously disintegrate brain's functionality, activate braking processes and amplify the negative emotional background of an individual. It is concluded that geomagnetic disturbances affect mainly emotional and vegetative spheres of human beings while characteristics reflecting personality properties do not undergo significant changes.

    We model large-scale ( ≈ 2000 km) impacts on a Mars-like planet using a Smoothed Particle Hydrodynamics code. The effects of material strength and of using different Equations of State on the post-impact material and temperature distributions are investigated. The properties of the ejected material in terms of escaping and disc mass are analysed as well. We also study potential numerical effects in the context of density discontinuities and rigid body rotation. We find that in the large-scale collision regime considered here (with impact velocities of 4 km/s), the effect of material strength is substantial for the post-impact distribution of the temperature and the impactor material, while the influence of the Equation of State is more subtle and present only at very high temperatures.

    Soil properties show high heterogeneity at different spatial scales and their correct characterization remains a crucial challenge over large areas. The aim of the study is to quantify the impact of different types of uncertainties that arise from the unresolved soil spatial variability on simulated hydrological states and fluxes. Three perturbation methods are presented for the characterization of uncertainties in soil properties. The methods are applied on the soil map of the upper Neckar catchment (Germany), as an example. The uncertainties are propagated through the distributed mesoscale hydrological model (mHM) to assess the impact on the simulated states and fluxes. The model outputs are analysed by aggregating the results at different spatial and temporal scales. These results show that the impact of the different uncertainties introduced in the original soil map is equivalent when the simulated model outputs are analysed at the model grid resolution (i.e. 500 m). However, several differences are identified by aggregating states and fluxes at different spatial scales (by subcatchments of different sizes or coarsening the grid resolution). Streamflow is only sensitive to the perturbation of long spatial structures while distributed states and fluxes (e.g. soil moisture and groundwater recharge) are only sensitive to the local noise introduced to the original soil properties. A clear identification of the temporal and spatial scale for which finer-resolution soil information is (or is not) relevant is unlikely to be universal. However, the comparison of the impacts on the different hydrological components can be used to prioritize the model improvements in specific applications, either by collecting new measurements or by calibration and data assimilation approaches. In conclusion, the study underlines the importance of a correct characterization of uncertainty in soil properties. With that, soil maps with additional information regarding the unresolved soil

    The mixed states of superconducting (SC) and normal (N) phases in one-dimensional systems are characterized by several phase slips and localization of the order parameter of the SC phase. The phenomenon is explained on the basis of a complex Ginzburg Landau (CGL) model. We present a simple analysis of the system on multiple scales to capture localization and phase slips when phases coexist. (fast track communication)

    2007-10-01

    The heterogeneity of mood episodes in bipolar disorders makes it difficult in some cases to define appropriate therapeutic strategies. Therefore, we proposed a new tool based on a dimensional approach, with five a priori subscales (emotional reactivity, thought processes, psychomotricity, motivation and sense perception) expected to help define subgroups of mood episodes predictive of the response to treatment. This study was designed to validate this multidimensional assessment of thymic states (MAThyS) scale. One hundred and ninety six subjects were included: 44 controls and 152 bipolar patients in various states: euthymic, manic or depressed. The MAThyS is a visual analog scale consisting of 20 items, ranging from inhibition to excitation. These items corresponded to five dimensions, namely: emotional reactivity, thought processes, psychomotricity, motivation and sense perception. They were selected since they represent clinically relevant quantitative traits. Confirmatory analyses demonstrated a good validity for this scale, fair convergent and divergent validity (multitrait multimethod analyses (MTMM)), good internal consistency both at global and dimensional level (Alpha Cronbach ranging from 0.70 to 0.93). The MathyS scale is moderately correlated with both the Montgomery and Asberg depression rating scale (MADRS) (depression score; r=-0.45) and the mania rating scale (MAS) (manic score; r=0.56). Some dimensions were linked (emotional reactivity and thought processes, r=0.71; psychomotricity and motivation, r=0.70). Analysing the divergent validity of items led us to redefine three of them. Following this validation step, exploratory analyses suggest that a four-dimension factorial structure is more appropriate. However, the statistical model is very close to the clinically relevant five-dimensional model. Further studies are needed to explore the relevance of retaining this dimension as a useful descriptive element.

    The utility-scale solar sector—defined here to include any ground-mounted photovoltaic (“PV”), concentrating photovoltaic (“CPV”), or concentrating solar power (“CSP”) project that is larger than 5 MWAC in capacity—has led the overall U.S. solar market in terms of installed capacity since 2012. It is expected to maintain its market-leading position for at least another five years, driven in part by December 2015’s three-year extension of the 30% federal investment tax credit (“ITC”) through 2019 (coupled with a favorable switch to a “start construction” rather than a “placed in service” eligibility requirement, and a gradual phase down of the credit to 10% by 2022). In fact, in 2016 alone, the utility-scale sector is projected to install more than twice as much new capacity as it ever has previously in a single year. This unprecedented boom makes it difficult, yet more important than ever, to stay abreast of the latest utility-scale market developments and trends. This report—the fourth edition in an ongoing annual series—is intended to help meet this need, by providing in-depth, annually updated, data-driven analysis of the utility-scale solar project fleet in the United States. Drawing on empirical project-level data from a wide range of sources, this report analyzes not just installed project costs or prices—i.e., the traditional realm of most solar economic analyses—but also operating costs, capacity factors, and power purchase agreement (“PPA”) prices from a large sample of utility-scale solar projects throughout the United States. Given its current dominance in the market, utility-scale PV also dominates much of this report, though data from CPV and CSP projects are also presented where appropriate.

  18. Psychological Spacetime

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available It has been an accepted scientific fact in physics for almost 100 years that time speeds up and slows down for an observer based on factors—such as motion and gravity—that affect space. Yet this fact, drawn from the theory of relativity, has not been widely integrated into the study of the psychology of time. The present article helps to fill in this gap between physics and psychology by reviewing evidence concerning what a psychological spacetime processor—one that accounted for the theory of relativity’s empirically validated predictions of the compensatory relationship between time and space—would look like. This model of the spacetime processor suggests that humans should have a psychological mechanism for slowing time down as motion speeds up, a prediction that already has widespread research support. We also discuss several novel hypotheses directly suggested by the spacetime model and a set of related speculations that emerge when considering spacetime (some of which have already received empirical support. Finally, we compare and contrast three very different potential reasons why we might have developed a spacetime processor in the first place. We conclude that the spacetime model shows promise for organizing existing data on time perception and generating novel hypotheses for researchers to pursue. Considering how humans might process spacetime helps reduce the existing gap between our understanding of physics and our understanding of human psychology.

    Political psychology is a dynamic field of research that offers a unique blend of approaches and methods in the social and cognitive sciences. Political psychologists explore the interactions between macrolevel political structures and microlevel factors such as decision-making processes, motivations, and perceptions. In this article, we provide a broad overview of the field, beginning with a brief history of political psychology research and a summary of the primary methodological approaches in the field. We then give a more detailed account of research on ideology and social justice, two topics experiencing a resurgence of interest in current political psychology. Finally, we cover research on political persuasion and voting behavior. By summarizing these major areas of political psychology research, we hope to highlight the wide variety of theoretical and methodological approaches of cognitive scientists working at the intersection of psychology and political science.

    The generalized uncertainty principle (GUP) is a modification of Heisenberg's Principle predicted by several theories of quantum gravity. It consists of a modified commutator between the position and momentum. In this work, we compute potentially observable effects that GUP implies for the harmonic oscillator, coherent, and squeezed states in quantum mechanics. In particular, we rigorously analyze the GUP-perturbed harmonic oscillator Hamiltonian, defining new operators that act as ladder operators on the perturbed states. We use these operators to define the new coherent and squeezed states. We comment on potential applications.

    This research explored the gender differences in resilience and psychological distress of patients with burns. In Pakistan, psychological states of patients with burns have not been widely studied, women making up as the neglected section of society lag far behind in availing the needful health facilities. It was hypothesized that there would be significant gender differences in resilience and psychological distress of patients with burns. The sample of the study consisted of 50 patients with burns, obtained from four different hospitals of Lahore. In order to investigate resilience and psychological distress, the State Trait Resilience Scales (Hiew, 2007) and Kessler Psychological Distress Scale (Kessler, 2001) were used. In addition to these, self-constructed demographic questionnaire was administered. The data was analyzed using SPSS version 16.0. Independent sample t-test was conducted to find gender differences in resilience and psychological distress. The findings from the current research revealed that there were significant gender differences in resilience and psychological distress of patients with burns. The insightful findings from the current research carry strong implications for the clinicians, psychologists and policy makers who can help to develop and implement the rehabilitation programs for the affected population and can launch resilience promoting programs that would help them in coping with burns in effective manner.

    Research of psychological factors associated with imminent preterm labor (PTL) is sparse, compared with considerable research of preterm birth. We explored state and trait psychological variables associated with PTL, both pre- and postpartum. During 2012-2014, 56 women hospitalized due to PTL, and 33 pregnant women without PTL, responded during gestational week 20-33, to a demographic questionnaire, the Big-Five Inventory (BFI), the Brief Symptom Inventory (BSI), the Fear of Childbirth Questionnaire, and the Maternal-Fetal Attachment Inventory (MFAS). At 4-6 weeks postpartum, 35 and 23 of the women in the respective groups responded online to the Edinburgh Postnatal Depression Scale (EPDS) and the Mother to Infant Bonding Scale (MIBS). Compared to women without PTL, women with PTL scored higher on neuroticism, openness to experience, and MFAS (p < 0.01 each), scored lower on consciousness and agreeableness (p < 0.01 each), and showed greater fear of childbirth (p < 0.05). Significant differences were not found in the postpartum variables of EPDS and MIBS. In the PTL group, MFAS (β = 0.36, p < 0.01), but not fear of childbirth (β = 0.08, p = NS), remained higher, after controlling for demographic variables and neuroticism. PTL was associated with personality variables, but not with psychological consequences, other than elevated prepartum attachment to the fetus.

  3. Decadal-scale changes of nitrate in ground water of the United States, 1988-2004.

    This study evaluated decadal-scale changes of nitrate concentrations in ground water samples collected by the USGS National Water-Quality Assessment Program from 495 wells in 24 well networks across the USA in predominantly agricultural areas. Each well network was sampled once during 1988-1995 and resampled once during 2000-2004. Statistical tests of decadal-scale changes of nitrate concentrations in water from all 495 wells combined indicate there is a significant increase in nitrate concentrations in the data set as a whole. Eight out of the 24 well networks, or about 33%, had significant changes of nitrate concentrations. Of the eight well networks with significant decadal-scale changes of nitrate, all except one, the Willamette Valley of Oregon, had increasing nitrate concentrations. Median nitrate concentrations of three of those eight well networks increased above the USEPA maximum contaminant level of 10 mg L(-1). Nitrate in water from wells with reduced conditions had significantly smaller decadal-scale changes in nitrate concentrations than oxidized and mixed waters. A subset of wells had data on ground water recharge date; nitrate concentrations increased in response to the increase of N fertilizer use since about 1950. Determining ground water recharge dates is an important component of a ground water trends investigation because recharge dates provide a link between changes in ground water quality and changes in land-use practices.

    One of the most promising candidates for the construction of ultrahigh-density storage media is low-dimensional atomic-scale magnetic nanostructures exhibiting magnetic bi- or multistability. Here we propose a novel route of locally controlling and switching magnetism in such nanostructures. Our ab initio studies reveal that externally applied electric field can be used for this purpose.

    Pressure-Volume-Temperature (PVT) measurements and broadband dielectric spectroscopy were carried out to investigate molecular dynamics and to test the validity of thermodynamic scaling of two homologous compounds of pharmaceutical activity: itraconazole and ketoconazole in the wide range of thermodynamic conditions. The pressure coefficients of the glass transition temperature (dT(g)/dp) for itraconazole and ketoconazole were determined to be equal to 183 and 228 K/GPa, respectively. However, for itraconazole, the additional transition to the nematic phase was observed and characterized by the pressure coefficient dT(n)/dp = 258 K/GPa. From PVT and dielectric data, we obtained that the liquid-nematic phase transition is governed by the relaxation time since it occurred at constant τ(α) = 10(-5) s. Furthermore, we plotted the obtained relaxation times as a function of T(-1)v(-γ), which has revealed that the validity of thermodynamic scaling with the γ exponent equals to 3.69 ± 0.04 and 3.64 ± 0.03 for itraconazole and ketoconazole, respectively. Further analysis of the scaling parameter in itraconazole revealed that it unexpectedly decreases with increasing relaxation time, which resulted in dramatic change of the shape of the thermodynamic scaling master curve. While in the case of ketoconazole, it remained the same within entire range of data (within experimental uncertainty). We suppose that in case of itraconazole, this peculiar behavior is related to the liquid crystals' properties of itraconazole molecule.

    2006-10-01

    Previous research has been devoted to the study of perceptual (e.g., number of depth cues) and cognitive (e.g., instructional set) factors that influence veridical size perception in perspective displays. However, considering that perspective displays have utility in high workload environments that often induce high arousal (e.g., aircraft cockpits), the present study sought to examine the effect of observers’ emotional state on the ability to perceive and judge veridical size. Within a dual-task paradigm, observers’ ability to make accurate size judgments was examined under conditions of induced emotional state (positive, negative, neutral) and high and low workload. Results showed that participants in both positive and negative induced emotional states were slower to make accurate size judgments than those not under induced emotional arousal. Results suggest that emotional state is an important factor that influences visual performance on perspective displays and is worthy of further study.

    During ethnographic fieldwork at a fertility clinic in Denmark, I became intrigued by emotions. In particular, I found an incidence labelled ‘psychological IVF’ theoretically provocative as it challenged my views on materializations, which I was preparing to study. This paper centres on the story...... of psychological IVF, and I use this narrative to consider emotions and materialization methodologically. I also ask how emotions at fertility clinics can be conceptualized to enable analysis of their materialization, change, and effects. In order to do so, I develop the term ‘emotional choreography......’. This theoretical work has three aims. First, it seeks to illustrate how the story of psychological IVF offers a rich range of materializations of emotions. Secondly, this work proposes a feminist materialist conceptualization of emotions that is both non-representational and posthuman. This conceptualization draws...

    The momentum space zero-range model is used to investigate universal properties of three interacting particles confined to two dimensions. The pertinent equations are first formulated for a system of two identical and one distinct particle and the two different two-body subsystems are characterized by two-body energies and masses. The three-body energy in units of one of the two-body energies is a universal function of the other two-body energy and the mass ratio. We derive convenient analytical formulae for calculations of the three-body energy as a function of these two independent parameters and exhibit the results as universal curves. In particular, we show that the three-body system can have any number of stable bound states. When the mass ratio of the distinct to identical particles is greater than 0.22, we find that at most two stable bound states exist, while for two heavy and one light mass an increasing number of bound states is possible. The specific number of stable bound states depends on the ratio of two-body bound state energies and on the mass ratio, and we map out an energy-mass phase diagram of the number of stable bound states. Realizable systems of both fermions and bosons are discussed in this framework.

  1. Foundation species' overlap enhances biodiversity and multifunctionality from the patch to landscape scale in southeastern United States salt marshes.

    Although there is mounting evidence that biodiversity is an important and widespread driver of ecosystem multifunctionality, much of this research has focused on small-scale biodiversity manipulations. Hence, which mechanisms maintain patches of enhanced biodiversity in natural systems and if these patches elevate ecosystem multifunctionality at both local and landscape scales remain outstanding questions. In a 17 month experiment conducted within southeastern United States salt marshes, we found that patches of enhanced biodiversity and multifunctionality arise only where habitat-forming foundation species overlap--i.e. where aggregations of ribbed mussels (Geukensia demissa) form around cordgrass (Spartina alterniflora) stems. By empirically scaling up our experimental results to the marsh platform at 12 sites, we further show that mussels--despite covering only approximately 1% of the marsh surface--strongly enhance five distinct ecosystem functions, including decomposition, primary production and water infiltration rate, at the landscape scale. Thus, mussels create conditions that support the co-occurrence of high densities of functionally distinct organisms within cordgrass and, in doing so, elevate salt marsh multifunctionality from the patch to landscape scale. Collectively, these findings suggest that patterns in foundation species' overlap drive variation in biodiversity and ecosystem functioning within and across natural ecosystems.We therefore argue that foundation species should be integrated in our conceptual understanding of forces that moderate biodiversity--ecosystem functioning relationships, approaches for conserving species diversity and strategies to improve the multifunctionality of degraded ecosystems.

    In this article, I explore the meaning of experiments in early twentieth century psychology, focusing on the qualitative experimental methodology of psychologist Frederic BARTLETT. I begin by contextualizing BARTLETT's experiments within the continental research tradition of his time, which...... was in a state of transition from a focus on elements (the concern of psychophysics) to a focus on wholes (the concern of Gestalt psychology). The defining feature of BARTLETT's early experiments is his holistic treatment of human responses, in which the basic unit of analysis is the active person relating...... to some material within the constraints of a social and material context. This manifests itself in a number of methodological principles that contrast with contemporary understandings of experimentation in psychology. The contrast is further explored by reviewing the history of "replications...

  6. Radial distribution function for hard spheres from scaled particle theory, and an improved equation of state

    Energy Technology Data Exchange (ETDEWEB)

    Reiss, H.; Casberg, R.V.

    1974-08-01

    Previous applications of scaled particle theory have been limited to the calculation of thermodynamic properties of fluids rather than structure. In the present paper, the theory is expanded so that it is capable of yielding the radial distribution function. The method is first illustrated by applying it to one-dimensional fluids of hard rods where, as in other theories, the radial distribution function is obtained exactly. It is then applied to a fluid of hard spheres where a closure condition is necessary. This condition is supported by recent work in scaled particle theory dealing with the thermodynamics of boundary layers. It is used to calculate the radial distribution function around a lambda-cule of varying size, including one of the size of a typical hard sphere solvent molecule. (40 refs.)

  7. Genuine multipartite entanglement of symmetric Gaussian states: Strong monogamy, unitary localization, scaling behavior, and molecular sharing structure

    Science.gov (United States)

    Adesso, Gerardo; Illuminati, Fabrizio

    2008-10-01

    We investigate the structural aspects of genuine multipartite entanglement in Gaussian states of continuous variable systems. Generalizing the results of Adesso and Illuminati [Phys. Rev. Lett. 99, 150501 (2007)], we analyze whether the entanglement shared by blocks of modes distributes according to a strong monogamy law. This property, once established, allows us to quantify the genuine N -partite entanglement not encoded into 2,…,K,…,(N-1) -partite quantum correlations. Strong monogamy is numerically verified, and the explicit expression of the measure of residual genuine multipartite entanglement is analytically derived, by a recursive formula, for a subclass of Gaussian states. These are fully symmetric (permutation-invariant) states that are multipartitioned into blocks, each consisting of an arbitrarily assigned number of modes. We compute the genuine multipartite entanglement shared by the blocks of modes and investigate its scaling properties with the number and size of the blocks, the total number of modes, the global mixedness of the state, and the squeezed resources needed for state engineering. To achieve the exact computation of the block entanglement, we introduce and prove a general result of symplectic analysis: Correlations among K blocks in N -mode multisymmetric and multipartite Gaussian states, which are locally invariant under permutation of modes within each block, can be transformed by a local (with respect to the partition) unitary operation into correlations shared by K single modes, one per block, in effective nonsymmetric states where N-K modes are completely uncorrelated. Due to this theorem, the above results, such as the derivation of the explicit expression for the residual multipartite entanglement, its nonnegativity, and its scaling properties, extend to the subclass of non-symmetric Gaussian states that are obtained by the unitary localization of the multipartite entanglement of symmetric states. These findings provide strong

    We predicted the diurnal cycles of hourly dissolved oxygen (DO) in streams by using a scaling-based empirical model. A single reference observation from each DO cycle was considered as a scaling parameter to convert the DO cycles into a single dimensionless diurnal curve, which was then estimated by employing an extended stochastic harmonic algorithm (ESHA). Hourly DO observations of growing season (May-August) during 2008-2015 from sixteen USGS water quality monitoring stations of the eastern U.S. were used for model calibrations and validations. The study sites incorporated a gradient in climate (tropical vs. temperate), land use (rural vs. urban vs. forest vs. coastal), and catchment size (2.4 - 184.0 mile2) — representing different USEPA level III ecoregions. The estimated model parameters showed a notable spatiotemporal robustness by collapsing into narrow ranges across the growing seasons and study sites. DO predicted using the site-specific, temporally averaged model parameters from a day-specific single reference observation exhibited good model fitting efficiency and accuracy. The model performance was also assessed by simulating the DO time-series using a regional scale parameter set that was obtained from the spatiotemporal aggregation (average) of the estimated parameters for all the sites. Further, model robustness to the individual and simultaneous perturbations in parameters was determined by calculating the analytical sensitivity and uncertainty measures. The study is a continuation of our previous research with a goal to develop a regional-scale predictive model of diurnal cycles of DO. The model can be used to estimate missing data in the observed fine-resolution time-series of DO with a single set of parameter across the eastern USA from limited observations. The fine-resolution DO time-series will be useful to dynamically assess the general health of the aquatic ecosystem.

    Land surface models have been used to assess water resources sustainability under changing Earth environment and increasing human water needs. Overwhelming observational records indicate that human activities have ubiquitous and pertinent effects on the hydrologic cycle; however, they have been crudely represented in large scale land surface models. In this study, we enhance an integrated continental-scale land hydrology model named Leaf-Hydro-Flood to better represent land-water management. The model is implemented at high resolution (5km grids) over the continental US. Surface water and groundwater are withdrawn based on actual practices. Newly added irrigation, water diversion, and dam operation schemes allow better simulations of stream flows, evapotranspiration, and infiltration. Results of various hydrologic fluxes and stores from two sets of simulation (one with and the other without human activities) are compared over a range of river basin and aquifer scales. The improved simulations of land hydrology have potential to build consistent modeling framework for human-water-climate interactions.

    Full Text Available This paper presents a radically new approach to cubic equations of state (EOS in which the Gibbs-Helmholtz equation is used to constrain the attraction or energy parameter, a. The resulting expressions for (, for pure components and (,, for mixtures contain internal energy departure functions and completely avoid the need to use empirical expressions like the Soave alpha function. Our approach also provides a novel and thermodynamically rigorous mixing rule for (,,. When the internal energy departure function is computed using Monte Carlo or molecular dynamics simulations as a function of current bulk phase conditions, the resulting EOS is a multiscale equation of state. The proposed new Gibbs-Helmholtz constrained (GHC cubic equation of state is used to predict liquid densities at high pressure and validated using experimental data from literature. Numerical results clearly show that the GHC EOS provides fast and accurate computation of liquid densities at high pressure, which are needed in the determination of gas hydrate equilibria.

  12. Large-scale information flow in conscious and unconscious states: an ECoG study in monkeys.

    Directory of Open Access Journals (Sweden)

    Full Text Available Consciousness is an emergent property of the complex brain network. In order to understand how consciousness is constructed, neural interactions within this network must be elucidated. Previous studies have shown that specific neural interactions between the thalamus and frontoparietal cortices; frontal and parietal cortices; and parietal and temporal cortices are correlated with levels of consciousness. However, due to technical limitations, the network underlying consciousness has not been investigated in terms of large-scale interactions with high temporal and spectral resolution. In this study, we recorded neural activity with dense electrocorticogram (ECoG arrays and used the spectral Granger causality to generate a more comprehensive network that relates to consciousness in monkeys. We found that neural interactions were significantly different between conscious and unconscious states in all combinations of cortical region pairs. Furthermore, the difference in neural interactions between conscious and unconscious states could be represented in 4 frequency-specific large-scale networks with unique interaction patterns: 2 networks were related to consciousness and showed peaks in alpha and beta bands, while the other 2 networks were related to unconsciousness and showed peaks in theta and gamma bands. Moreover, networks in the unconscious state were shared amongst 3 different unconscious conditions, which were induced either by ketamine and medetomidine, propofol, or sleep. Our results provide a novel picture that the difference between conscious and unconscious states is characterized by a switch in frequency-specific modes of large-scale communications across the entire cortex, rather than the cessation of interactions between specific cortical regions.

  13. Soviet psychology and psychophysiology.

    Pavlov's experiments, begun long before the revolution, have always been generously supported by the Soviet state. However, their far-reaching ontological and methodological implication gained an official and commanding position to Soviet biomedical and psychosocial (as distinct from socioeconomic) sciences only in 1950 with the Resolution of the 28 June-4 July Joint Pavlovian Session of the Soviet Academy of Sciences and Academy of Medical Sciences. In the biomedical sciences, present-day Soviet Pavlovianism may best be conceived of as (i) a doctrine of nervism (a Russian term)-the ubiquity of neural control of bodily reactions (neural, neurosomatic, neurovisceral, and neurohumoral) and (ii) a doctrine of what might be called concomitantism (my term )-the ready and radical modification of these reactions by concomitant reactions; or, viewed more generally and somewhat differently, as (iii) a far-reaching physicalistic psychosomaticism or, rather, a neuroviscerosomaticism. Psychophysiology-or higher nervous activity-is the key discipline here. With scores of research institutes, it is indeed a very well-established, wide-scoped, and faradvanced faradvanced science that, in both present achievements and future capabilities, is a challenge to American and Western equivalents. On the other hand, in the psychosocial sciences and the key discipline of psychology proper, unmitigated Pavlovian physicalism and objectivism is met head on by (i) the unbending postulate of dialectical materialism of "the specific emergent efficacy of consciousness and subjective conscious categories" as well as by (ii) the simple consideration that a consistent Pavlovianism is a fully autarchic psychology and needs no other science of psychology on top of it. A large portion of current Soviet psychological theory in psychology proper is thus primarily a textual and exegetic collation and conciliation of the views of Pavlov with those of Marx, Engels, and Lenin (until recently and, to some

  16. Modeling Ranking, Time Trade-Off and Visual Analogue Scale Values for EQ-5D Health States

    Background There is rising interest in eliciting health state valuations using rankings. Due to their relative simplicity, ordinal measurement methods may offer an attractive practical alternative to cardinal methods, such as time trade-off (TTO) and visual analog scale (VAS). In this paper, we explore alternative models for estimating cardinal health state values from rank responses in a unique multi-country database. We highlight an estimation challenge pertaining to health states just below perfect health (the ‘non-optimal gap’) and propose an analytic solution to ameliorate this problem. Methods Using rank, a standardized protocol developed by the EuroQol Group, TTO and VAS responses were collected for 43 health states in eight countries: Slovenia, Argentina, Denmark, Japan, Netherlands, Spain, United Kingdom, and United States, yielding a sample of 179,431 state responses from 11,483 subjects. States were described using the EQ-5D system, which allows for three different possible levels on five different dimensions of health. We estimated conditional logit and probit regression models for rank responses. The regressions included 17 health-state attribute variables reflecting specific levels on each dimension and counts of different levels across dimensions. This flexible specification accommodates previously published valuation models, such as models applied in the United Kingdom and United States. In addition to fitting standard conditional logit and probit models, which assume equal variance across health states (homoskedasticity), we examined a heteroskedastic probit model that assumes no variance for the two points anchoring the scale (“optimal health” and “dead”) and relaxes the equal-variance assumption for all other states. Rank-based predictions for the 243 unique states defined by the EQ-5D system were compared to predictions from conventional linear models fitted to TTO and VAS responses. Results By construction, the TTO and VAS models

    Over the past 15 years, the northeastern United States has seen a statistically significant increase in the frequency of extreme precipitation events that is larger and more widespread than anywhere else in the country. This increase in events is more likely to be associated with frontal and low-pressure systems, rather than being caused by more tropical cyclones impacting the region.

  12. An Urban Cellular Automata Model for Simulating Dynamic States on a Local Scale

    Directory of Open Access Journals (Sweden)

    Jenni Partanen

    2016-12-01

    Full Text Available In complex systems, flexibility and adaptability to changes are crucial to the systems’ dynamic stability and evolution. Such resilience requires that the system is able to respond to disturbances by self-organizing, which implies a certain level of entropy within the system. Dynamic states (static, cyclical/periodic, complex, and chaotic reflect this generative capacity, and correlate with the level of entropy. For planning complex cities, we need to develop methods to guide such autonomous progress in an optimal manner. A classical apparatus, cellular automaton (CA, provides such a tool. Applications of CA help us to study temporal dynamics in self-organizing urban systems. By exploring the dynamic states of the model’s dynamics resulting from different border conditions it is possible to discover favorable set(s of rules conductive to the self-organizing dynamics and enable the system’s recovery at the time of crises. Level of entropy is a relevant measurement for evaluation of these dynamic states. The 2-D urban cellular automaton model studied here is based on the microeconomic principle that similar urban activities are attracted to each other, especially in certain self-organizing areas, and that the local dynamics of these enclaves affect the dynamics of the urban region by channeling flows of information, goods and people. The results of the modeling experiment indicate that the border conditions have a major impact on the model’s dynamics generating various dynamic states of the system. Most importantly, it seemed that the model could simulate a favorable, complex dynamic state with medium entropy level which may refer to the continuous self-organization of the system. The model provides a tool for exploring and understanding the effects of boundary conditions in the planning process as various scenarios are tested: resulting dynamics of the system can be explored with such “planning rules” prior to decisions, helping to

    India has ambitious goals for high utilization of variable renewable power from wind and solar, and deployment has been proceeding at a rapid pace. The western state of Gujarat currently has the largest amount of solar generation of any Indian state, with over 855 Megawatts direct current (MWDC). Combined with over 3,240 MW of wind, variable generation renewables comprise nearly 18% of the electric-generating capacity in the state. A new historic 10-kilometer (km) gridded solar radiation data set capturing hourly insolation values for 2002-2011 is available for India. We apply an established method for downscaling hourly irradiance data to one-minute irradiance data at potential PV power production locations for one year, 2006. The objective of this report is to characterize the intra-hour variability of existing and planned photovoltaic solar power generation in the state of Gujarat (a total of 1.9 gigawatts direct current (GWDC)), and of five possible expansion scenarios of solar generation that reflect a range of geographic diversity (each scenario totals 500-1,000 MW of additional solar capacity). The report statistically analyzes one year's worth of power variability data, applied to both the baseline and expansion scenarios, to evaluate diurnal and seasonal power fluctuations, different timescales of variability (e.g., from one to 15 minutes), the magnitude of variability (both total megawatts and relative to installed solar capacity), and the extent to which the variability can be anticipated in advance. The paper also examines how Gujarat Energy Transmission Corporation (GETCO) and the Gujarat State Load Dispatch Centre (SLDC) could make use of the solar variability profiles in grid operations and planning.

    Full Text Available Purpose The purpose of this study was to cross-validate the factor structure of the previously developed Student Perceptions of Team-Based Learning (TBL Scale among students in an entry-level doctor of physical therapy (DPT program in the United States. Methods Toward the end of the semester in 2 patient/client management courses taught using TBL, 115 DPT students completed the Student Perceptions of TBL Scale, with a response rate of 87%. Principal component analysis (PCA and confirmatory factor analysis (CFA were conducted to replicate and confirm the underlying factor structure of the scale. Results Based on the PCA for the validation sample, the original 2-factor structure (preference for TBL and preference for teamwork of the Student Perceptions of TBL Scale was replicated. The overall goodness-of-fit indices from the CFA suggested that the original 2-factor structure for the 15 items of the scale demonstrated a good model fit (comparative fit index, 0.95; non-normed fit index/Tucker-Lewis index, 0.93; root mean square error of approximation, 0.06; and standardized root mean square residual, 0.07. The 2 factors demonstrated high internal consistency (alpha= 0.83 and 0.88, respectively. DPT students taught using TBL viewed the factor of preference for teamwork more favorably than preference for TBL. Conclusion Our findings provide evidence supporting the replicability of the internal structure of the Student Perceptions of TBL Scale when assessing perceptions of TBL among DPT students in patient/client management courses.

    Except for frozen water in ice and glaciers, groundwater is the world's largest distributed store of freshwater and has strategic importance to global food and water security. In this paper, the most recent advances quantifying groundwater depletion (GWD) are comprehensively reviewed. This paper critically evaluates the recently advanced modeling approaches estimating GWD at regional and global scales, and the evidence of feedbacks to the Earth system including sea-level rise associated with GWD. Finally, critical challenges and opportunities in the use of groundwater are identified for the adaption to growing food demand and uncertain climate.

    Dissemination of innovations is widely considered the sine qua non for system improvement. At least two dozen states are rolling-out evidence-based mental health practices targeted at children and families using trainings, consultations, webinars, and learning collaboratives to improve quality and outcomes. In New York State (NYS) a group of researchers, policy-makers, providers and family support specialists have worked in partnership since 2002 to redesign and evaluate the children’s mental health system. Five system strategies driven by empirically-based practices and organized within a state-supported infrastructure have been used in the child and family service system with over 2,000 providers: (a) business practices; (b) use of health information technologies in quality improvement; (c) specific clinical interventions targeted at common childhood disorders; (d) parent activation; and (e) quality indicator development. The NYS system has provided a laboratory for naturalistic experiments. We describe these initiatives, key findings and challenges, lessons learned for scaling, and implications for creating evidence-based implementation policies in state systems. PMID:24460518

  18. Anthropogenic hydrological cycle disturbance at a regional scale: State-wide evapotranspiration trends (1979-2015) across Nebraska, USA

    Science.gov (United States)

    Szilagyi, Jozsef

    2018-02-01

    Trends in monthly evapotranspiration (ET) rates across Nebraska, the most intensely irrigated state within the US, were calculated by the calibration-free version of the nonlinear complementary relationship of evaporation over the 1979-2015 period utilizing North American Regional Reanalysis (NARR) net radiation, 10-m wind velocity, as well as Parameter Regression Independent Slope Model (PRISM) air- and dew-point temperature data. State-averaged modeled ET rates rose by 5.5 mm decade-1 due to the presence of wide-spread large-scale irrigation projects in accordance with a 2.4 mm decade-1 increase in PRISM precipitation (P) and a simultaneous -2.8 mm decade-1 drop in United States Geological Survey's state-averaged annual streamflow rates, raising the state-wide ET to P ratio from 0.89 to 0.91 over the modeled time-period. ET rates over irrigated crops increased by 7 mm decade-1 despite a -4.4 mm decade-1 drop in precipitation rates. A similar increase in ET rates (6 mm decade-1) required 8.1 mm decade-1 increase in precipitation rates across the non-irrigated Sand Hills of Nebraska. Published NARR ET rates are unable to pick up this unusual regional trend. Since an increase in precipitation rates should normally decrease the ET ratio, as predicted by the Budyko curve, this study yields evidence on how dramatically sustained large-scale irrigation can alter the regional hydrologic cycle not only through a) trivially depleting streamflow rates and/or lowering groundwater table levels; b) suppressing precipitation locally (while enhancing it a long distance downwind), but also; c) reversing the trajectory of the regional ET ratio under generally increasing trends of precipitation.

    Full Text Available Background. The aim of this study was to investigate the association of oxytocin with trait and state psychological factors in type 2 diabetic patients. Methods. OXT and psychological variables were analyzed from 86 controlled diabetic patients (glycosylated haemoglobin A1c (HbA1c < 7% from 45 uncontrolled diabetic patients (HbA1c ≥ 7. Psychological characteristics were assessed with the Eysenck Personality Questionnaire (EPQ, while state psychological characteristics were measured with the Symptom Checklist 90-R (SCL 90-R. Blood samples were taken for measuring oxytocin in both subgroups during the initial phase of the study. One year later, the uncontrolled diabetic patients were reevaluated with the use of the same psychometric instruments. Results. During the first evaluation of the uncontrolled diabetic patients, a statistically significant positive relationship between the levels of OXT and psychoticism in EPQ rating scale (P<0.013 was observed. For controlled diabetic patients, a statistically significant negative relationship between oxytocin and somatization (P<0.030, as well as obsessive-compulsive scores (P<0.047 in SCL-90 rating scale, was observed. During the second assessment, the values of OXT decreased when the patients managed to control their metabolic profile. Conclusions. The OXT is in association with psychoticism, somatization, and obsessionality may be implicated in T2DM.

    Science.gov (United States)

    Tojo Radimy, Raymond; Dudoignon, Patrick

    2017-12-01

    The paper is focused on clayey dominated sediments of coastal marshes of the West Atlantic coast of France because of their homogeneity in texture and mineralogy, and their vertical structure evolution from dried and solid state in surface down to saturated plastic-to-liquid state in depth. It proposes a “review” of the complementary petrographic and hydromechanical data obtained on theses clay dominated soils and a method of calculation for the relationships prevailing between the hydro-mechanical properties and microstructure behaviour of the clay matrices. This tool, based on the shrinkage curve of the clay matrix is applied as aid to the hydraulic management of marshlands regarding the soil-plant interactions.
