    Anxiety and depressive symptoms are common in childhood, however problems in need of intervention may not be identified. Children at risk for developing more severe problems can be identified based on elevated symptom levels. Quality of life and self-esteem are important functional domains and may provide additional valuable information. Schoolchildren (n = 915), aged 9-13, who considered themselves to be more anxious or sad than their peers, completed self-reports of anxiety (Multidimensional Anxiety Scale for children (MASC-C), depression (The Short Mood and Feelings Questionnaire; SMFQ), quality of life (Kinder Lebensqualität Fragebogen; KINDL) and self-esteem (Beck self-concept inventory for youth (BSCI-Y) at baseline of a randomized controlled indicative study. Using multivariate analyses, we examined the relationships between internalizing symptoms, quality of life and self-esteem in three at-risk symptom groups. We also examined gender and age differences. 52.1 % of the screened children scored above the defined at-risk level reporting elevated symptoms of either Anxiety and Depression (Combined group) (26.6 %), Depression only (15.4 %) or Anxiety only (10.2 %). One-way ANOVA analysis showed significant mean differences between the symptom groups on self-reported quality of life and self-esteem. Regression analysis predicting quality of life and self-esteem showed that in the Depression only group and the Combined group, symptom levels were significantly associated with lower self-reported scores on both functional domains. In the Combined group, older children reported lower quality of life and self-esteem than younger children. Internalizing symptoms explained more of the variance in quality of life than in self-esteem. Symptoms of depression explained more of the variance than anxious symptoms. Female gender was associated with higher levels of internalizing symptoms, but there was no gender difference in quality of life and self

    Research suggesting that political conservatives are happier than political liberals has relied exclusively on self-report measures of subjective well-being. We show that this finding is fully mediated by conservatives' self-enhancing style of self-report (study 1; N = 1433) and then describe three studies drawing from "big data" sources to assess liberal-conservative differences in happiness-related behavior (studies 2 to 4; N = 4936). Relative to conservatives, liberals more frequently used positive emotional language in their speech and smiled more intensely and genuinely in photographs. Our results were consistent across large samples of online survey takers, U.S. politicians, Twitter users, and LinkedIn users. Our findings illustrate the nuanced relationship between political ideology, self-enhancement, and happiness and illuminate the contradictory ways that happiness differences can manifest across behavior and self-reports.

    Full Text Available This study explores listeners' experience of music-evoked sadness. Sadness is typically assumed to be undesirable and is therefore usually avoided in everyday life. Yet the question remains: Why do people seek and appreciate sadness in music? We present findings from an online survey with both Western and Eastern participants (N = 772. The survey investigates the rewarding aspects of music-evoked sadness, as well as the relative contribution of listener characteristics and situational factors to the appreciation of sad music. The survey also examines the different principles through which sadness is evoked by music, and their interaction with personality traits. Results show 4 different rewards of music-evoked sadness: reward of imagination, emotion regulation, empathy, and no "real-life" implications. Moreover, appreciation of sad music follows a mood-congruent fashion and is greater among individuals with high empathy and low emotional stability. Surprisingly, nostalgia rather than sadness is the most frequent emotion evoked by sad music. Correspondingly, memory was rated as the most important principle through which sadness is evoked. Finally, the trait empathy contributes to the evocation of sadness via contagion, appraisal, and by engaging social functions. The present findings indicate that emotional responses to sad music are multifaceted, are modulated by empathy, and are linked with a multidimensional experience of pleasure. These results were corroborated by a follow-up survey on happy music, which indicated differences between the emotional experiences resulting from listening to sad versus happy music. This is the first comprehensive survey of music-evoked sadness, revealing that listening to sad music can lead to beneficial emotional effects such as regulation of negative emotion and mood as well as consolation. Such beneficial emotional effects constitute the prime motivations for engaging with sad music in everyday life.

    In 1899, the Spanish painter Joaquín Sorolla represented, in a large canvas, a group of children probably with sequels of poliomyelitis bathing at Valencia's beach. The title of this painting was Sad Legacy. This work contributed to the international diffusion of Sorolla's artistic creation. We briefly report some facts regarding the painter and his work referring to those portraits of children and especially of sick children.

  16. SAD effects on grantmanship

    CERN Document Server

    Lozano, George A

    2014-01-01

    Seasonal affective disorder (SAD) is a state of depression induced by a lack of sufficient sunlight that occurs at high latitudes during the fall and winter. One effect of SAD is that causes people to be more risk-adverse, an effect that should be considered by granting agencies of high latitude countries. Funding agencies often have programmes aimed at high-risk, innovative research. However, the time of the year during which these purposefully high-risk proposals are evaluated usually does not take into consideration the effects of SAD. In high-latitude countries (e.g., Canada, UK, Nordic and Baltic countries), evaluating proposals for high-risk programmes during the late fall might significantly detract from the very purpose of such programmes. At this time of the year, grant evaluators might be in a darkness-induced state of mild depression. As such, evaluators might be more likely to opt for safe investments, more of the same, the well established, which is the antithesis of innovative research.

  18. Emotional Tears Facilitate the Recognition of Sadness and the Perceived Need for Social Support

    2013-01-01

    Full Text Available The tearing effect refers to the relevance of tears as an important visual cue adding meaning to human facial expression. However, little is known about how people process these visual cues and their mediating role in terms of emotion perception and person judgment. We therefore conducted two experiments in which we measured the influence of tears on the identification of sadness and the perceived need for social support at an early perceptional level. In two experiments (1 and 2, participants were exposed to sad and neutral faces. In both experiments, the face stimuli were presented for 50 milliseconds. In experiment 1, tears were digitally added to sad faces in one condition. Participants demonstrated a significant faster recognition of sad faces with tears compared to those without tears. In experiment 2, tears were added to neutral faces as well. Participants had to indicate to what extent the displayed individuals were in need of social support. Study participants reported a greater perceived need for social support to both sad and neutral faces with tears than to those without tears. This study thus demonstrated that emotional tears serve as important visual cues at an early (pre-attentive level.

  19. Sad music induces pleasant emotion.

    In general, sad music is thought to cause us to experience sadness, which is considered an unpleasant emotion. As a result, the question arises as to why we listen to sad music if it evokes sadness. One possible answer to this question is that we may actually feel positive emotions when we listen to sad music. This suggestion may appear to be counterintuitive; however, in this study, by dividing musical emotion into perceived emotion and felt emotion, we investigated this potential emotional response to music. We hypothesized that felt and perceived emotion may not actually coincide in this respect: sad music would be perceived as sad, but the experience of listening to sad music would evoke positive emotions. A total of 44 participants listened to musical excerpts and provided data on perceived and felt emotions by rating 62 descriptive words or phrases related to emotions on a scale that ranged from 0 (not at all) to 4 (very much). The results revealed that the sad music was perceived to be more tragic, whereas the actual experiences of the participants listening to the sad music induced them to feel more romantic, more blithe, and less tragic emotions than they actually perceived with respect to the same music. Thus, the participants experienced ambivalent emotions when they listened to the sad music. After considering the possible reasons that listeners were induced to experience emotional ambivalence by the sad music, we concluded that the formulation of a new model would be essential for examining the emotions induced by music and that this new model must entertain the possibility that what we experience when listening to music is vicarious emotion.

    The SAD (safety and arming device) is an indispensable fuse component that ensures safe and reliable performance during the use of ammunition. Because the application of electronic devices for smart munitions is increasing, miniaturization of the SAD has become one of the key issues for next-generation artillery fuses. Based on MEMS technology, various types of miniaturized SADs have been proposed and fabricated. However, none of them have been reported to have been used in actual munitions due to their lack of high impact endurance and complicated explosive train arrangements. In this research, a new MEMS SAD using a ball driven mechanism, is successfully demonstrated based on a UV LIGA (lithography, electroplating and molding) process. Unlike other MEMS SADs, both high impact endurance and simple structure were achieved by using a ball driven mechanism. The simple structural design also simplified the fabrication process and increased the processing yield. The ball driven type MEMS SAD performed successfully under the desired safe and arming conditions of a spin test and showed fine agreement with the FEM simulation result, conducted prior to its fabrication. A field test was also performed with a grenade launcher to evaluate the SAD performance in the firing environment. All 30 of the grenade samples equipped with the proposed MEMS SAD operated successfully under the high-G setback condition.

  3. The relationship between coping style and loneliness in adolescents: can "sad passivity" be adaptive?

    1991-06-01

    The authors' purpose in this paper was to examine how the use of the "sad passive" coping style may be related to adolescent self-reported loneliness. Subjects were asked to complete the revised UCLA Loneliness Scale (Russell, Peplau, & Cutrona, 1980) to determine self-reported loneliness and the Coping with Loneliness Questionnaire (CLQ; Rubenstein & Shaver, 1980) in order to examine coping styles. We hypothesized that those adolescents whose coping strategies fell into the category of sad passivity described by Rubenstein and Shaver would indicate greater loneliness than those adolescents whose coping strategies fell into other categories. Results indicated that sad passivity was used by both lonely and nonlonely adolescents, but that nonlonely youngsters resorted to this method only temporarily and in preparation for a more active coping style. Lonely teens, on the other hand, appeared to remain in the sad-passive mode to a maladaptive degree. These results were discussed in terms of their importance for theories of adolescent loneliness and for possible intervention strategies.

    Superior migration and malunion of a fractured greater tuberosity can lead to mechanical subacromial impingement with resultant ongoing pain and limitation of abduction. We describe such a case successfully treated with arthroscopic excision of the protruding portion of the greater tuberosity, with marked improvement in pain and range of movement. The greater tuberosity was exposed by elevating the supraspinatus tendon, which was reattached at the end of the procedure. This case, along with outcomes of similar techniques previously reported in literature suggest that arthroscopic excision of a superiorly malunited greater tuberosity is associated with good symptomatic outcome and preservation of rotator cuff function.

    2017-01-01

    Artworks with sad and affectively negative content have repeatedly been reported to elicit positive aesthetic appreciation. This topic has received much attention both in the history of poetics and aesthetics as well as in recent studies on sad films and sad music. However, poetry and aesthetic evaluations of joyful and sad poetry have received only little attention in empirical studies to date. We collected beauty and liking ratings for 24 sad and 24 joyful poems from 128 participants. Following previous studies, we computed an integrated measure for overall aesthetic appreciation based on the beauty and liking ratings to test for differences in appreciation between joyful and sad poems. Further, we tested whether readers' judgments are related to their affinity for poetry. Results show that sad poems are rated significantly higher for aesthetic appreciation than joyful poems, and that aesthetic appreciation is influenced by the participants' affinity for poetry.

    Research has suggested that both age and personality play a role in emotional experience and regulation, but these variables have not been considered together to determine the relative contribution of each. This study simultaneously examined age and agreeableness differences in the experience of sad stimuli. Participants were 46 younger adults (age, M = 22.04 years, SD = 5.41 years) and 48 older adults (age, M = 74.23, SD = 7.82 years). Participants were asked to predict how sad stimuli (i.e., sad photos) would make them feel and were then measured on their actual reaction to the stimuli (reactivity) as well as on their emotional recovery. Agreeableness, but not age, was related to predicted levels of sadness, such that the more agreeable, the higher the predicted sadness (beta = 0.37). In contrast to expectations, prediction accuracy was not related to age or agreeableness. For emotional reactivity, agreeableness (beta = 0.16), but not age, was related to reactivity to sad stimuli (i.e., more agreeable, higher reactivity). Finally, age (beta = 0.14) was significantly related to emotional recovery such that the older adults reported lower levels of sadness at posttest than did the younger adults. Similarly, people who were more agreeable also reported better emotional recovery (beta = 0.15). These relationships were not affected by depression or pretest sadness ratings. Overall, these findings suggest distinct roles for age and agreeableness in predicting different components of the emotion regulation process. An individual with advanced age, high levels of agreeableness, or both may be well-positioned for resilience throughout the emotion regulation process.

  8. Population distribution of the sagittal abdominal diameter (SAD from a representative sample of US adults: comparison of SAD, waist circumference and body mass index for identifying dysglycemia.

    Full Text Available The sagittal abdominal diameter (SAD measured in supine position is an alternative adiposity indicator that estimates the quantity of dysfunctional adipose tissue in the visceral depot. However, supine SAD's distribution and its association with health risk at the population level are unknown. Here we describe standardized measurements of SAD, provide the first, national estimates of the SAD distribution among US adults, and test associations of SAD and other adiposity indicators with prevalent dysglycemia.In the 2011-2012 National Health and Nutrition Examination Survey, supine SAD was measured ("abdominal height" between arms of a sliding-beam caliper at the level of the iliac crests. From 4817 non-pregnant adults (age ≥ 20; response rate 88% we used sample weights to estimate SAD's population distribution by sex and age groups. SAD's population mean was 22.5 cm [95% confidence interval 22.2-22.8]; median was 21.9 cm [21.6-22.4]. The mean and median values of SAD were greater for men than women. For the subpopulation without diagnosed diabetes, we compared the abilities of SAD, waist circumference (WC, and body mass index (BMI, kg/m(2 to identify prevalent dysglycemia (HbA1c ≥ 5.7%. For age-adjusted, logistic-regression models in which sex-specific quartiles of SAD were considered simultaneously with quartiles of either WC or BMI, only SAD quartiles 3 (p<0.05 vs quartile 1 and 4 (p<0.001 vs quartile 1 remained associated with increased dysglycemia. Based on continuous adiposity indicators, analyses of the area under the receiver operating characteristic curve (AUC indicated that the dysglycemia model fit for SAD (age-adjusted was 0.734 for men (greater than the AUC for WC, p<0.001 and 0.764 for women (greater than the AUC for WC or BMI, p<0.001.Measured inexpensively by bedside caliper, SAD was associated with dysglycemia independently of WC or BMI. Standardized SAD measurements may enhance assessment of dysfunctional adiposity.

    Orbital metastasis in systemic cancer is known to occur and occurs in up to 7% of all systemic cancers. Orbital features typically present after the diagnosis of the primary tumor. In about 20% of cases, there is no known primary cancer at the time of presentation with orbital metastatic disease. Here we report a case of a 60-year-old male smoker, in whom proptosis, due to metastasis in greater wing of left sphenoid bone secondary to bronchogenic carcinoma, was the initial symptom. We could not find in literature metastasis to greater wing of sphenoid bone due to small cell carcinoma of lung.

    Full Text Available Abstract Malignant peripheral nerve sheath tumors (MPNSTs are rare soft tissue tumors that arise from a peripheral nerve or exhibit nerve sheath differentiation. Most of these tumors arise on the trunk, extremities, or head and neck regions; they are very rarely located in the abdominal cavity. The patient was a 71-year-old man who was referred to our hospital for a mass and pain in the right lower abdomen. Abdominal computed tomography revealed a large (9 × 9 cm, well-circumscribed, lobulated, heterogeneously enhanced mass in the pelvis. Exploratory laparotomy revealed a large mass in the greater omentum, and the tumor was completely excised. Histopathological analysis revealed that the tumor was composed of spindle cells with high mitotic activity. On staining the tumor, positive results were obtained for S-100 but negative results were obtained for c-kit, cluster of differentiation (CD34, α-smooth muscle actin, and desmin. These findings strongly supported a diagnosis of MPNST primarily arising from the greater omentum. To the best of our knowledge, this is the first reported case of an MPNST arising from the greater omentum.

    Full Text Available We assessed spatial and temporal variation in reporting probability of banded Greater Snow Geese (Chen caerulescens atlantica shot by hunters in eastern North America and evaluated potential residual biases in kill rate estimation. Adult Greater Snow Geese were marked with reward (value: US$10, $20, $30, $50, and $100 and standard bands ($0, control in the Canadian Arctic from 2003 to 2005. We used a spatially explicit multinomial model based on 200 direct recoveries from 4256 banded geese to estimate reporting rate and harvest rate. We found that reporting rate for standard bands varied over time whereas harvest rate was higher in Canada than in the U.S. The reporting probability increased from 0.40 ± 0.11 in the first year of the study to 0.82 ± 0.14 and 0.84 ± 0.13 the second and third years, respectively. Overall, these reporting rates are higher than two previous estimates for this population, which leads to lower estimates of kill rate. However, the large annual differences in reporting rates found in this study lead to uncertainty in the estimation of kill rate. We suggest that the increase in reporting rate in the last two year of the study may be due to the dissemination of information among hunters regarding the presence of reward bands on birds, resulting in increased reporting rate for all bands. This raises issues about the need to adequately inform the public in such large-scale studies to avoid undesirable temporal trends over the course of the study.

    Folk medicine is a rich source of useful therapeutic tools. Nevertheless, use of medicinal plants can have unwanted, negative effects. By means of the description of an adverse reaction to a herbal remedy, we highlight the need for better efficacy-toxicity studies on these products. To report a case of possible Chelidonium majus L. (Greater celandine)-induced hepatitis and evaluate the past published cases. We outlined the main features of hepatitis associated with use of Chelidonium majus by providing a review of cases reported and analysing in detail a new one. Several cases of acute hepatitis related to Greater celandine consumption were found in the literature. The assessment for causality using Naranjo probability scale showed a probable relationship between the liver injury and the consumption of Chelidonium majus in the case we described. Our case, along with the other ones reported in the literature, increases the concern about the safety of oral use of Chelidonium majus. Plants used in traditional medicine are not necessarily harmless. Customers and prescribers should be aware of this, especially when a herbal drug is used with therapeutic purposes in absence of reliable studies of clinical efficacy and benefit-risk assessment.

    Primary osteosarcoma of skull base is extremely rare. We present a case of primary osteosarcoma arising in greater wing of sphenoid in a child. Our patient had an incomplete excision after which he received adjuvant chemotherapy and radiotherapy. There was good response to adjuvant chemoradiotherapy and the patient is disease free at a follow-up of 18 months. Treatment of skull base osteosarcomas is difficult, as complete excision is often not possible. To the best of our knowledge, this is the first case of sphenoid wing osteosarcoma in childhood to be reported in literature.

    2009-01-01

    The aim of this study was to determine the prevalence of seasonal affective disorder (SAD) in Greenlanders and Danes living at four different latitudes in Greenland. A Seasonal Pattern Assessment Questionnaire (SPAQ) was mailed to 6021 men and women between the ages of 18 and 59 years living in four different municipalities in Greenland. The recipients were randomly selected from the National Population Register. Approximately 9% of the respondents met the criteria for SAD, and the incidence of SAD varied between a southern municipality and three northern municipalities. The prevalence of SAD was particularly high in northern municipalities. No significant difference was found in the prevalence of SAD between Greenlanders and Danes. The results are comparable with other population studies that have reported a high prevalence of SAD in arctic areas. The clinical implications of our findings and the possibilities for introducing light therapy should be assessed in future studies.

    Full Text Available The purpose of this study was to estimate the degree of seasonality and prevalence of winter- and summer-type seasonal affective disorder (SAD in African immigrant college students in comparison with African American peers. A convenience sample of 246 African immigrants and 599 African Americans studying in Washington, D.C. completed the Seasonal Pattern Assessment Questionnaire (SPAQ, which was used to calculate a global seasonality score (GSS and to estimate the prevalence of winter- and summer-type SAD. Degree of seasonality was related to a complex interaction between having general awareness of SAD, ethnicity, and gender. A greater percentage of African students reported experiencing a problem with seasonal changes relative to African American students, and had summer SAD, but the groups did not differ on GSS and winter SAD. African students reported more difficulties with seasonal changes than their African American peers, which could represent a manifestation of incomplete acclimatization to a higher latitude and temperate climate. As Africans also had a greater rate of summer SAD, this argues against acclimatization to heat.

  20. Suspected Greater Celandine hepatotoxicity: liver-specific causality evaluation of published case reports from Europe.

    2012-03-01

    In 21 published case reports, the use of the herb Greater Celandine (GC) (Chelidonium majus L.) has been causally related to liver injury, but a variety of confounding variables were evident that might have offset causality. This study reanalyses causality levels in these cases with a liver-specific causality evaluation method. All 21 cases were submitted to the liver-specific, standardized, structured, quantitative and updated scale of the Council for International Organizations of Medical Sciences. This scale considers, among other items, latency period, course of alanine aminotransferase after treatment discontinuation, risk factors, comedication and alternative causes. Using this method for assessment, causality for GC was highly probable in two and probable in six cases, with lower causality grading in the remaining 13 cases. In these patients, causality for GC was possible in 10 cases and excluded in three cases. On the basis of the eight cases with highly probable and probable causality gradings, GC hepatotoxicity represents an idiosyncratic reaction of the metabolic type, whereas immunologic or obligatory hepatotoxic features are lacking. In some cases, alternative diagnoses and poor data quality were confounding variables that reduced causality levels. Confounding variables reduced causality levels for GC in reported cases of liver injury, but there is still striking evidence for herb-induced liver injury by GC with high causality gradings. GC hepatotoxicity is caused by an idiosyncratic reaction of the metabolic form, but there is uncertainty with respect to its culprit(s).

    The purpose of this study was to examine whether dispositional sadness predicted children's prosocial behavior and if sympathy mediated this relation. Constructs were measured when children (N = 256 at Time 1) were 18-, 30-, and 42-months old. Mothers and non-parental caregivers rated children’s sadness; mothers, caregivers, and fathers rated children’s prosocial behavior; sympathy (concern and hypothesis testing) and prosocial behavior (indirect and direct, as well as verbal at older ages) were assessed with a task in which the experimenter feigned injury. In a panel path analysis, 30-month dispositional sadness predicted marginally higher 42-month sympathy; in addition, 30-month sympathy predicted 42-month sadness. Moreover, when controlling for prior levels of prosocial behavior, 30-month sympathy significantly predicted reported and observed prosocial behavior at 42 months. Sympathy did not mediate the relation between sadness and prosocial behavior (either reported or observed). PMID:25663753

    1989-01-01

    The Greater Confinement Disposal Test (GCDT) was conducted at the Nevada Test Site to demonstrate an alternative method for management of high-specific-activity (HSA) low-level waste (LLW). The GCDT was initially conceived as a method for managing small volumes of highly concentrated tritium wastes, which, due to their environmental mobiilty, are considered unsuitable for routine shallow land disposal. Later, the scope of the GCDT was increased to address a variety of other "problem" HSA wastes including isotope sources and thermal generating wastes. The basic design for the GCDT evolved from a series of studies and assessments. Operational design objectives were to (1) emplace the wastes at a depth sufficient to minimize or eliminate routine environmental transport mechanisms and instrusion scenarios and (2) provide sufficient protection for operations personnel in the handling of HSA sources. To achieve both objectives, a large diameter borehole was selected. The GCDT consisted of a borehole 3 meters (10 feet) in diameter and 36 meters (120 feet) deep, surrounded by nine monitoring holes at varying radii. The GCDT was instrumented for the measurement of temperature, moisture, and soil-gas content. Over one million curies of HSA LLW were emplaced in GCDT. This report reviews the development of the GCDT project and presents analyses of data collected.

  4. Flexible parasympathetic responses to sadness facilitate spontaneous affect regulation.

    The ability of the parasympathetic nervous system to flexibly adapt to changes in environmental context is thought to serve as a physiological indicator of self-regulatory capacity, and deficits in parasympathetic flexibility appear to characterize affective disorders such as depression. However, whether parasympathetic flexibility (vagal withdrawal to emotional or environmental challenges such as sadness, and vagal augmentation during recovery from sadness) could facilitate the effectiveness of adaptive affect regulation strategies is not known. In a study of 178 undergraduate students, we evaluated whether parasympathetic flexibility in response to a sad film involving loss would enhance the effectiveness of regulatory strategies (reappraisal, distraction, and suppression) spontaneously employed to reduce negative affect during a 2-min uninstructed recovery period following the induction. Parasympathetic reactivity and recovery were indexed by fluctuations in respiratory sinus arrhythmia and high-frequency heart rate variability. Cognitive reappraisal and distraction were more effective in attenuating negative affect among individuals with more parasympathetic flexibility, particularly greater vagal augmentation during recovery, relative to individuals with less parasympathetic flexibility. In contrast, suppression was associated with less attenuation of negative affect, but only among individuals who also had less vagal withdrawal during the sad film. Alternative models provided partial support for reversed directionality, with reappraisal predicting greater parasympathetic recovery, but only when individuals also experienced greater reductions in negative affect. These results suggest that contextually appropriate parasympathetic reactivity and recovery may facilitate the success of affect regulation. Impairments in parasympathetic flexibility could confer risk for affective disorders due to attenuated capacity for effective self-regulation. © 2017 Society for

    Full Text Available Incidental affective states tend to influence stereotyping in counterintuitive way: experimentally induced happiness leads to more stereotyping while experimentally induced sadness leads to less stereotyping. It was therefore predicted that happy subjects would a. would make more stereotype-consistent errors in memory task; b. attribute more stereotypical features to a specific ethnic group, and c. be less sensitive to ethnic discrimination in comparison to sad subjects. In a sample of 90 high school students from Belgrade, Serbia, differently valenced affects were successfully induced using 'autobiographic recollection' procedure. Experiment 1 showed that happy and sad subjects did not differ in the number of stereotype consistent errors in memory task. In experiment 2, however, happy subjects in comparison to sad subjects attributed more stereotypic traits to a non-stereotypical exemplar of a national category and expected him to behave more stereotypically in the future. Additionally, in thought listing task, happy subjects recorded more irrelevant and less story-focused thoughts in comparison to sad subjects. Finally, in Experiment 3 (N=66 sad subjects demonstrated more sensitivity to ethnic discrimination in comparison to happy subjects. These findings are discussed in terms of the impact of emotional experience on social information-processing strategies.

    In summary, a case has been presented of a 26-year-old man who on admission showed a mild right proptosis and swelling of the right temple. Roentgenograms of the skull demonstrated loss of the right innominate line. CT studies after contrast demonstrated a sharply-demarcated, destructive area of the right greater sphenoid wing with an enhancing, spindle-shaped, soft tissue mass observed around the bony defect. Increased uptake was demonstrated on a radionuclide scan. The lesion was surgically removed and proved to be a desmoid. (orig./SHA).

  11. How report cards on physicians, physician groups, and hospitals can have greater impact on consumer choices.

    Public report cards with quality and cost information on physicians, physician groups, and hospital providers have proliferated in recent years. However, many of these report cards are difficult for consumers to interpret and have had little impact on the provider choices consumers are making. To gain a more focused understanding of why these reports cards have not been more successful and what improvements could be made, we interviewed experts and surveyed registrants at the March 2011 AHRQ National Summit on Public Reporting for Consumers in Health Care. We found broad agreement that public reporting has been disconnected from consumer decisions about providers because of weaknesses in report card content, design, and accessibility. Policy makers have an opportunity to change the landscape of public reporting by taking advantage of advances in measurement, data collection, and information technology to deliver a more consumer-centered report card. Overcoming the constraint of limited public funding, and achieving the acceptance of providers, is critical to realizing future success.

    This document contains two parts. Part I, Greater-Than-Class-C Low-Level Radioactive Waste Transportation Strategy, addresses the requirements, responsibilities, and strategy to transport and receive these wastes. The strategy covers (a) transportation packaging, which includes shipping casks and waste containers; (b) transportation operations relating to the five facilities involved in transportation, i.e., waste originator, interim storage, dedicated storage, treatment, and disposal; (c) system safety and risk analysis; (d) routes; (e) emergency preparedness and response; and (o safeguards and security. A summary of strategic actions is provided at the conclusion of Part 1. Part II, Institutional Plan for Greater-Than-Class C Low-Level Radioactive Waste Packaging and Transportation, addresses the assumptions, requirements, and institutional plan elements and actions. As documented in the Strategy and Institutional Plan, the most challenging issues facing the GTCC LLW Program shipping campaign are institutional issues closely related to the strategy. How the Program addresses those issues and demonstrates to the states, local governments, and private citizens that the shipments can and will be made safely will strongly affect the success or failure of the campaign.

    Capillary haemangiomas are frequent benign tumours in infancy. The authors report a case of capillary haemangioma of the greater omentum, discovered in a child of 5 months of age and studied with US, CT and MRI. The localization of such a lesion in the greater omentum is exceptional. Abdominal US revealed a heterogeneous, multinodular intraperitoneal mass. Doppler study demonstrated hypervascularity of the lesion. CT localized the mass to the greater omentum. The mass was hypodense on the unenhanced scan and enhanced massively after injection. The infant suffered a reaction to contrast medium during the CT. MRI demonstrated a mass which was hypointense on T1-weighted images and hyperintense on T2-weighted images. Laparotomy confirmed the location of the mass within the greater omentum and allowed resection of the tumour. (orig.)

    Stearoyl-acyl carrier protein desaturase (SAD), locating in the plastid stroma, is an important fatty acid biosynthetic enzyme in higher plants. SAD catalyzes desaturation of stearoyl-ACP to oleyl-ACP and plays a key role in determining the homeostasis between saturated fatty acids and unsaturated fatty acids, which is an important player in cold acclimation in plants. Here, four new full-length cDNA of SADs (ScoSAD, SaSAD, ScaSAD and StSAD) were cloned from four Solanum species, Solanum commersonii, S. acaule, S. cardiophyllum and S. tuberosum, respectively. The ORF of the four SADs were 1182 bp in length, encoding 393 amino acids. A sequence alignment indicated 13 amino acids varied among the SADs of three wild species. Further analysis showed that the freezing tolerance and cold acclimation capacity of S. commersonii are similar to S. acaule and their SAD amino acid sequences were identical but differed from that of S. cardiophyllum, which is sensitive to freezing. Furthermore, the sequence alignments between StSAD and ScoSAD indicated that only 7 different amino acids at residues were found in SAD of S. tuberosum (Zhongshu8) against the protein sequence of ScoSAD. A phylogenetic analysis showed the three wild potato species had the closest genetic relationship with the SAD of S. lycopersicum and Nicotiana tomentosiformis but not S. tuberosum. The SAD gene from S. commersonii (ScoSAD) was cloned into multiple sites of the pBI121 plant binary vector and transformed into the cultivated potato variety Zhongshu 8. A freeze tolerance analysis showed overexpression of the ScoSAD gene in transgenic plants significantly enhanced freeze tolerance in cv. Zhongshu 8 and increased their linoleic acid content, suggesting that linoleic acid likely plays a key role in improving freeze tolerance in potato plants. This study provided some new insights into how SAD regulates in the freezing tolerance and cold acclimation in potato. PMID:25825911

    Toxic liver injury due to the herb Greater Celandine (GC) (Chelidonium majus L.) has been assumed in patients originating from various European countries and created concern. Based on regulatory and liver unspecific ad hoc causality assessments in 22 spontaneous cases of Germany, causality levels for GC were considered probable in 16 and possible in 6 cases. We now analyzed the data of these 22 cases regarding their causality levels employing the liver specific, standardized, structured and quantitative assessment method of the updated scale of CIOMS (Council for International Organizations of Medical Sciences). Causality for GC was found highly probable (n=2), probable (n=6), possible (n=10), unlikely (n=1), and excluded (n=3). Thus, causality could be upgraded in 2 cases to a highly probable causality level, but had to be down graded to excluded, unlikely, or possible causality levels in 3, 1, or 9 cases, respectively. GC hepatotoxicity shows a hepatocellular pattern of liver injury with female gender predominance. On average, age of the patients was 56.4 years, treatment 36.4 days, and latency period until first symptoms and jaundice 29.8 and 35.6 days, respectively. This analysis therefore provides further evidence for the existence of GC hepatotoxicity as a distinct form of herb induced liver injury, but due to poor data quality the causal association between GC use and liver injury is less strong than hitherto assumed. We propose replacement of the regulatory organ unspecific by a liver specific causality assessment method in cases of herb induced liver injury as well as stricter pharmacovigilance strategies towards improvements of data quality. Toxicological studies are now warranted to elucidate the mechanism(s) of human GC hepatotoxicity that represents a European issue. Copyright © 2011 Elsevier Inc. All rights reserved.

  16. College students who have an eveningness preference report lower self-control and greater procrastination.

    2008-11-01

    Previous research suggests a possible link between eveningness and general difficulties with self-regulation (e.g., evening types are more likely than other chronotypes to have irregular sleep schedules and social rhythms and use substances). Our study investigated the relationship between eveningness and self-regulation by using two standardized measures of self-regulation: the Self-Control Scale and the Procrastination Scale. We predicted that an eveningness preference would be associated with poorer self-control and greater procrastination than would an intermediate or morningness preference. Participants were 308 psychology students (mean age=19.92 yrs) at a small Canadian college. Students completed the self-regulation questionnaires and Morningness/Eveningness Questionnaire (MEQ) online. The mean MEQ score was 46.69 (SD=8.20), which is intermediate between morningness and eveningness. MEQ scores ranged from definite morningness to definite eveningness, but the dispersion of scores was skewed toward more eveningness. Pearson and partial correlations (controlling for age) were used to assess the relationship between MEQ score and the Self-Control Scale (global score and 5 subscale scores) and Procrastination Scale (global score). All correlations were significant. The magnitude of the effects was medium for all measures except one of the Self-Control subscales, which was small. A multiple regression analysis to predict MEQ score using the Self-Control Scale (global score), Procrastination Scale, and age as predictors indicated the Self-Control Scale was a significant predictor (accounting for 20% of the variance). A multiple regression analysis to predict MEQ scores using the five subscales of the Self-Control Scale and age as predictors showed the subscales for reliability and work ethic were significant predictors (accounting for 33% of the variance). Our study showed a relationship between eveningness and low self-control, but it did not address whether the

    Several tight, naturally-fractured, gas-productive formations in the Greater Green River Basin (GGRB) in Wyoming have been exploited using conventional vertical well technology. Typically, hydraulic fracture treatments must be performed in completing these wells to increase gas production rates to economic levels. However, with the maturation of horizontal drilling technology hydraulic fracture treatments may not be the most effective method for improving gas production from these tight reservoirs. Two of the most prolific tight gas reservoirs in the Green River Basin, the Frontier and the Mesaverde, are candidates for the application of horizontal well completion technology. The objective of the proposed project is to apply the DOE`s technical concept to the Second Frontier Formation on the western flank of the Rock Springs Uplift. Previous industry attempts to produce in commercial quantities from the Second Frontier Formation have been hampered by lack of understanding of both the in-situ natural fracture system and lack of adequate stimulation treatments. The proposed technical approach involves drilling a vertical characterization well to the Second Frontier Formation at a depth of approximately 16,000 ft. from a site located about 18 miles northwest of Rock Springs, Wyoming. Logging, coring, and well testing information from the vertical well will be used to design a hydraulic fracturing treatment and to assess the resulting production performance. Data from the vertical drilling phase will be used to design a 2,500 to 3,000-ft lateral wellbore which will be kicked off from the vertical hole and extend into the blanket marine sandstone bench of the Second Frontier Formation. The trajectory of this wellbore will be designed to intersect the maximum number of natural fractures to maximize production rates. Production testing of the resulting completion will provide an assessment of reserve potential related to horizontal lateral completions.

    This study tested three alternative explanations for research indicating a positive, but heterogeneous relationship between self-reported posttraumatic growth (PTG) and posttraumatic stress symptoms (PSS): (a) the third-variable hypothesis that the relationship between PTG and PSS is a spurious one driven by positive relationships with resource loss, (b) the growth over time hypothesis that the relationship between PTG and PSS is initially a positive one, but becomes negative over time, and (c) the moderator hypothesis that resource loss moderates the relationship between PTG and PSS such that PTG is associated with lower levels of PSS as loss increases. A nationally representative sample (N = 1622) of Israelis was assessed at three time points during a period of ongoing violence. PTG, resource loss, and the interaction between PTG and loss were examined as lagged predictors of PSS to test the proposed hypotheses. Results were inconsistent with all three hypotheses, showing that PTG positively predicted subsequent PSS when accounting for main and interactive effects of loss. Our results suggest that self-reported PTG is a meaningful but counterintuitive predictor of poorer mental health following trauma.

    Trypanosoma evansi (Steel, 1885) Balbiani, is the cause of trypanosomiasis (Surra) which multiples in the blood and body fluids. The incubation period varies from 7-15 days. The mortality rate was up to 20% and fatality rate may reach up to 100% in untreated camels. Three hundred randomly selected camels were 200 males 4-6 years old and 100 females 10-15 years. They were examined clinically and diagnosed by Giemsa stained blood smear, anti- trypanosomiasis-antibodies by ELISA and urine Thymol turbidity test for natural infection with T. evani (Surra). The results showed that camels were naturally infected with T. evansi as indicated by stained blood film examination and/or ELISA. Infection in males was 6.0% (stained blood smears), 8.0% (ELISA) and 5.0% (urine thymol turbidity test). In females the infection rate was 9.0%, 24.0% and 12% respectively. By correlation with suggestive clinical manifestations, ELISA proved to be more sensitive and specific (13.3%) than stained blood films (10.0%) and urine Thymol turbidity test (7.3%). Regarding humans, one out of 30 was positive as indicated by ELISA and stained blood smear but was negative by urine thymol turbidity test. The human case was successfully treated as indicated clinically, parasitologically and serologically. This is the first reported Egyptian human case of trypanosomiasis evansi, a neglected zoonosis.

  20. Enjoying Sad Music: Paradox or Parallel Processes?

    Science.gov (United States)

    2016-01-01

    Enjoyment of negative emotions in music is seen by many as a paradox. This article argues that the paradox exists because it is difficult to view the process that generates enjoyment as being part of the same system that also generates the subjective negative feeling. Compensation theories explain the paradox as the compensation of a negative emotion by the concomitant presence of one or more positive emotions. But compensation brings us no closer to explaining the paradox because it does not explain how experiencing sadness itself is enjoyed. The solution proposed is that an emotion is determined by three critical processes-labeled motivational action tendency (MAT), subjective feeling (SF) and Appraisal. For many emotions the MAT and SF processes are coupled in valence. For example, happiness has positive MAT and positive SF, annoyance has negative MAT and negative SF. However, it is argued that in an aesthetic context, such as listening to music, emotion processes can become decoupled. The decoupling is controlled by the Appraisal process, which can assess if the context of the sadness is real-life (where coupling occurs) or aesthetic (where decoupling can occur). In an aesthetic context sadness retains its negative SF but the aversive, negative MAT is inhibited, leaving sadness to still be experienced as a negative valanced emotion, while contributing to the overall positive MAT. Individual differences, mood and previous experiences mediate the degree to which the aversive aspects of MAT are inhibited according to this Parallel Processing Hypothesis (PPH). The reason for hesitancy in considering or testing PPH, as well as the preponderance of research on sadness at the exclusion of other negative emotions, are discussed.

    Full Text Available Chemosignals from human body fluids may modulate biological functions in humans. The objective of this study was to examine whether chemosignals from human sad tears and postprandial plasma modulate appetite. We obtained fasting and postprandial plasma from male participants and sad tears and saline, which was trickled below the eyelids, from female volunteers. These samples were then randomly distributed to male participants to sniff with a band-aid containing 100 µl of each fluid on four consecutive days in a double-blind fashion. We checked appetite by a visual analogue scale (VAS and food intake by measuring the consumption of a test meal. In addition, the serum levels of total testosterone and LH were measured. Twenty men (mean age 26.3±4.6 years were enrolled in this study. They could not discriminate between the smell of fasting and postprandial plasma and the smell of sad tears and trickled saline. Appetite and the amount of food intake were not different between the groups. Although the VAS ratings of appetite correlated with the food intake upon sniffing fasting plasma, postprandial plasma, and trickled saline, there was no such correlation upon sniffing sad tears. In addition, the decrease in serum testosterone levels from the baseline was greater with sad tears than with the trickled saline (-28.6±3.3% vs. -14.0±5.2%; P = 0.019. These data suggest that chemosignals from human sad tears and postprandial plasma do not appear to reduce appetite and food intake. However, further studies are necessary to examine whether sad tears may alter the appetite-eating behavior relation.

    Full Text Available Some people experience pleasant emotion when listening to sad music. Therefore, they can enjoy listening to it. In the current study, we aimed to investigate such apparently paradoxical emotional mechanisms and focused on the influence of individuals’ trait empathy, which has been reported to associate with emotional responses to sad music and a preference for it. Eighty-four elementary school children (42 males and 42 females, mean age 11.9 years listened to two kinds of sad music and rated their emotional state and liking towards them. In addition, trait empathy was assessed using the IRI scale, which comprises four sub-components: Empathic Concern, Personal Distress, Perspective Taking, and Fantasy. We conducted a path analysis and tested our proposed model that hypothesized that trait empathy and its sub-components would affect the preference for sad music directly or indirectly, mediated by the emotional response to the sad music. Our findings indicated that fantasy, a sub-component of trait empathy, was directly associated with liking sad music. Additionally, perspective taking ability, another sub-component of trait empathy, was correlated with the emotional response to sad music. Furthermore, the experience of pleasant emotions contributed to liking sad music.

  5. Spacetime Average Density (SAD) Cosmological Measures

    The measure problem of cosmology is how to obtain normalized probabilities of observations from the quantum state of the universe. This is particularly a problem when eternal inflation leads to a universe of unbounded size so that there are apparently infinitely many realizations or occurrences of observations of each of many different kinds or types, making the ratios ambiguous. There is also the danger of domination by Boltzmann Brains. Here two new Spacetime Average Density (SAD) measures are proposed, Maximal Average Density (MAD) and Biased Average Density (BAD), for getting a finite number of observation occurrences by using properties of the Spacetime Average Density (SAD) of observation occurrences to restrict to finite regions of spacetimes that have a preferred beginning or bounce hypersurface. These measures avoid Boltzmann brain domination and appear to give results consistent with other observations that are problematic for other widely used measures, such as the observation of a positive cosmolo...

Objective. To gain a better understanding of complex relationships between weight satisfaction, weight-related health behaviors, and health outcomes. Design. Cross-sectional analysis of data from the Aerobics Center Longitudinal Study (ACLS. Participants. Large mixed-gender cohort of primarily white, middle-to-upper socioeconomic status (SES adults with baseline examination between 1987 and 2002 (n=19,003. Main Outcome Variables. Weight satisfaction, weight-related health behaviors, chronic health conditions, and clinical health indicators. Statistical Analyses Performed. Chi-square test, t-tests, and linear and multivariate logistic regression. Results. Compared to men, women were more likely to be dieting (32% women; 18% men and had higher weight dissatisfaction. Men and women with greater weight dissatisfaction reported more dieting, yo-yo dieting, and snacking and consuming fewer meals, being less active, and having to eat either more or less than desired to maintain weight regardless of weight status. Those who were overweight or obese and dissatisfied with their weight had the poorest health. Conclusion. Greater satisfaction with one’s weight was associated with positive health behaviors and health outcomes in both men and women and across weight status groups.

    The accepted conceptual design of the experimental Subcritical Assembly in Dubna (SAD) is based on the MOX core with a nominal unit capacity of 25 kW (thermal). This corresponds to the multiplication coefficient $k_{\\rm eff} =0.95$ and accelerator beam power 1 kW. A subcritical assembly driven with the existing 660 MeV proton accelerator at the Joint Institute for Nuclear Research has been modelled in order to make choice of the optimal parameters for the future experiments. The Monte Carlo method was used to simulate neutron spectra, energy deposition and doses calculations. Some of the calculation results are presented in the paper.

    Studies of children with atypical emotional experience demonstrate that childhood exposure to high levels of hostility and threat biases emotion perception. This study investigates emotion processing, in former child soldiers and non-combatant civilians. All participants have experienced prolonged violence exposure during childhood. The study, carried out in Sierra Leone, aimed to examine the effects of exposure to and forced participation in acts of extreme violence on the emotion processing of young adults war survivors. A total of 76 young, male adults (38 former child soldier survivors and 38 civilian survivors) were tested in order to assess participants' ability to identify four different facial emotion expressions from photographs and movies. Both groups were able to recognize facial expressions of emotion. However, despite their general ability to correctly identify facial emotions, participants showed a significant response bias in their recognition of sadness. Both former soldiers and civilians made more errors in identifying expressions of sadness than in the other three emotions and when mislabeling sadness participants most often described it as anger. Conversely, when making erroneous identifications of other emotions, participants were most likely to label the expressed emotion as sadness. In addition, while for three of the four emotions participants were better able to make a correct identification the greater the intensity of the expression, this pattern was not observed for sadness. During movies presentation the recognition of sadness was significantly worse for soldiers. While both former child soldiers and civilians were found to be able to identify facial emotions, a significant response bias in their attribution of negative emotions was observed. Such bias was particularly pronounced in former child soldiers. These findings point to a pervasive long-lasting effect of childhood exposure to violence on emotion processing in later life.

    Puerarin (PUE), an isoflavone purified from the root of Pueraria lobata (Chinese herb), has been reported to attenuate learning and memory impairments in the transgenic mouse model of Alzheimer's disease (AD). In the present study, we tested PUE in a sporadic AD (SAD) mouse model which was induced by the intracerebroventricular injection of streptozotocin (STZ). The mice were administrated PUE (25, 50, or 100mg/kg/d) for 28 days. Learning and memory abilities were assessed by the Morris water maze test. After behavioral test, the biochemical parameters of oxidative stress (glutathione peroxidase (GSH-Px), superoxide dismutases (SOD), and malondialdehyde (MDA)) were measured in the cerebral cortex and hippocampus. The SAD mice exhibited significantly decreased learning and memory ability, while PUE attenuated these impairments. The activities of GSH-Px and SOD were decreased while MDA was increased in the SAD animals. After PUE treatment, the activities of GSH-Px and SOD were elevated, and the level of MDA was decreased. The middle dose PUE was more effective than others. These results indicate that PUE attenuates learning and memory impairments and inhibits oxidative stress in STZ-induced SAD mice. PUE may be a promising therapeutic agent for SAD.

    Full Text Available Abstract Background Neurons assemble into a functional network through a sequence of developmental processes including neuronal polarization and synapse formation. In Caenorhabditis elegans, the serine/threonine SAD-1 kinase is essential for proper neuronal polarity and synaptic organization. To determine if SAD-1 activity regulates the establishment or maintenance of these neuronal structures, we examined its temporal requirements using a chemical-genetic method that allows for selective and reversible inactivation of its kinase activity in vivo. Results We generated a PP1 analog-sensitive variant of SAD-1. Through temporal inhibition of SAD-1 kinase activity we show that its activity is required for the establishment of both neuronal polarity and synaptic organization. However, while SAD-1 activity is needed strictly when neurons are polarizing, the temporal requirement for SAD-1 is less stringent in synaptic organization, which can also be re-established during maintenance. Conclusion This study reports the first temporal analysis of a neural kinase activity using the chemical-genetic system. It reveals that neuronal polarity and synaptic organization have distinct temporal requirements for SAD-1.

    2016-09-01

    Full Text Available The Greater Yellowstone Ecosystem (GYE, located in the Central Rocky Mountains of western North America, is one of the largest nearly intact temperate-zone ecosystems on Earth. Here, Lactarius is an important component of ectomycorrhizal communities in many habitat types, from low elevation riparian areas to high elevation conifer forests and alpine tundra. Molecular phylogenetic analyses of ITS and RPB2 gene sequences along with detailed morphological examination confirm at least 20 Lactarius species, as well as three varieties, and one unresolved species group in the GYE. Eight taxa are reported from the GYE for the first time, and nearly every major ectomycorrhizal host plant in the GYE appears to have at least one Lactarius species associated with it. Broad intercontinental distributions are suggested for alpine Salix and Betula associates, and for certain subalpine Picea and aspen (Populus spp. associates. Some species appear to be restricted to western North America with Pinus, Pseudotsuga or Abies. The distribution and/or host affinities of others is not clear due in part to ambiguous host assignment, taxonomic problems or the relative rarity with which they have been reported.

    Though substance use is often associated with elevated risk-taking in real-world scenarios, many risk-taking tasks in experimental psychology using financial gambles fail to find significant differences between individuals with substance use disorders and healthy controls. We assessed whether participants using marijuana would show a greater propensity for risk-taking in distinct domains including, but not limited to, financial risk-taking. In the current study, we assessed risk-taking in young adult (age 18-25) regular marijuana users and in non-using control participants using a domain-specific risk-taking self-report scale (DOSPERT) encompassing five domains of risk-taking (social, financial, recreational, health/safety, and ethical). We also measured behavioral risk-taking using a laboratory monetary risk-taking task. Marijuana users and controls reported significant differences on the social, health/safety, and ethical risk-taking scales, but no differences in the propensity to take recreational or financial risks. Complementing the self-report finding, there were no differences between marijuana users and controls in their performance on the laboratory risk-taking task. These findings suggest that financial risk-taking may be less sensitive than other domains of risk-taking in assessing differences in risky behavior between those who use marijuana and those who do not. In order to more consistently determine whether increased risk-taking is a factor in substance use, it may be necessary to use both monetary risk-taking tasks and complementary assessments of non-monetary-based risk-taking measures.

  19. SAD2 in Arabidopsis Functions in Trichome Initiation through Mediating GL3 Function and Regulating GL1,TTG1 and GL2 Expression

    Most genes identified that control Arabidopsls trichome initiation and formation are transcription factors or regulatory components in transcriptional networks and include GLABROUS1 (GL1), GLABRA2 (GL2), GLABRA3 (GL3) and TRANSPARENT TESTA GLABRA1 (TTG1). Herein, we report that an importin β-like protein, SENSITIVE TO ABA AND DROUGHT2 (SAD2),is required for trichome initiation. Mutations in SAD2 disrupted trichome initiation resulting in reduced trichome number,but had no effect on trichome development or root hair number and development. Expression levels of GL1, MYB23, GL2 and TTG1 were reduced in shoots of sad2 mutants while expression levels of GL3 and ENHANCER OF GLABRA3 (EGL3)were enhanced. Overexpression of GL3 increased trichome numbers in wild type but not in sad2 mutants, indicating that the function of the GL3 protein is altered in the sad2 mutants. In contrast, overexpression of GFP-GL1 decreased trichome number in both wild type and sad2. Double mutant analysis of gl1 sad2 and gl3 sad2 indicated that SAD2 functions genetically, at least in part, in the same pathway with these two genes. Co-immunoprecipitation indicated that the sad2 mutation does not disrupt formation of the TTG1-GL3-GL1 complex. Analysis of GFP fusions of GL1, GL2, GL3 and TTG1 suggested that these proteins are most likely not direct cargo of SAD2. Our data suggest that SAD2 is involved in trichome initiation by regulating these nuclear genes.

  20. Explaining Sad People’s Memory Advantage for Faces

    2017-01-01

    Sad people recognize faces more accurately than happy people (Hills et al., 2011). We devised four hypotheses for this finding that are tested between in the current study. The four hypotheses are: (1) sad people engage in more expert processing associated with face processing; (2) sad people are motivated to be more accurate than happy people in an attempt to repair their mood; (3) sad people have a defocused attentional strategy that allows more information about a face to be encoded; and (4) sad people scan more of the face than happy people leading to more facial features to be encoded. In Experiment 1, we found that dysphoria (sad mood often associated with depression) was not correlated with the face-inversion effect (a measure of expert processing) nor with response times but was correlated with defocused attention and recognition accuracy. Experiment 2 established that dysphoric participants detected changes made to more facial features than happy participants. In Experiment 3, using eye-tracking we found that sad-induced participants sampled more of the face whilst avoiding the eyes. Experiment 4 showed that sad-induced people demonstrated a smaller own-ethnicity bias. These results indicate that sad people show different attentional allocation to faces than happy and neutral people. PMID:28261138

    Conservation efforts for greater sage-grouse (Centrocercus urophasianus), hereafter sage-grouse, are underway across the range of this species. Over 70 local working groups have been established and are implementing on-the-ground sage-grouse oriented conservation projects. Early on in this process, the California Department of Fish and Game (CDFG) recognized the need to join in these efforts and received funding from the U.S. Fish and Wildlife Service (USFWS) under the Candidate Species Conservation Program to help develop a species conservation plan for sage-grouse in the Mono County area. This conservation plan covers portions of Alpine, Mono, and Inyo counties in California and Douglas, Esmeralda, Lyon, and Mineral counties in Nevada. A concurrent effort underway through the Nevada Governor's Sage-grouse Conservation Team established Local Area Working Groups across Nevada and eastern California. The Mono County populations of sage-grouse were encompassed by the Bi-State Local Planning Area, which was comprised of six population management units (PMUs). The state agencies from California (CDFG) and Nevada (Nevada Department of Wildlife; NDOW) responsible for the management of sage-grouse agreed to utilize the process that had begun with the Nevada Governor's Team in order to develop local plans for conservation planning and implementation. Resources from the USFWS were applied to several objectives in support of the development of the Bi-State Local Area Sage-grouse Conservation Plan through a grant to the U.S. Geological Survey (USGS). Objectives included: (1) participate in the development of the Bi-State Conservation Plan, (2) compile and synthesize existing sage-grouse data, (3) document seasonal movements of sage-grouse, (4) identify habitats critical to sage-grouse, (5) determine survival rates and identify causal factors of mortality, (6) determine nest success and brood success of sage-grouse, and (7) identify sage-grouse lek sites.

    Following a legal agreement with the European Union (EU), Philip Morris International (PMI) commissions a yearly report ('Project Star', PS) on the European illicit cigarette trade from KPMG, the global accountancy firm. Review of PS 2010 report. Comparison with data from independent sources including a 2010 pan-European survey (N=18,056). Within PS, data covering all 27 EU countries are entered into a model. While the model itself seems appropriate, concerns are identified with the methodologies underlying the data inputs and thus their quality: there is little transparency over methodologies; interview data underestimate legal non-domestic product partly by failing to account for legal cross-border sales; illicit cigarette estimates rely on tobacco industry empty pack surveys which may overestimate illicit; and there is an over-reliance on data supplied by PMI with inadequate external validation. Thus, PMI sales data are validated using PMI smoking prevalence estimates, yet PMI is unable to provide sales (shipment) data for the Greek islands and its prevalence estimates differ grossly from independent data. Consequently, comparisons with independent data suggest PS will tend to overestimate illicit cigarette levels particularly where cross-border shopping is frequent (Austria, Finland, France) and in Western compared with Eastern European countries. The model also provides data on the nature of the illicit cigarette market independent of seizure data suggesting that almost a quarter of the illicit cigarette market in 2010 comprised PMI's own brands compared with just 5% counterfeited PMI brands; a finding hidden in PMI's public representation of the data. PS overestimates illicit cigarette levels in some European countries and suggests PMI's supply chain control is inadequate. Its publication serves the interests of PMI over those of the EU and its member states. PS requires greater transparency, external scrutiny and use of independent data. Published by the BMJ

  9. SAD5 Stereo Correlation Line-Striping in an FPGA

    Science.gov (United States)

    Villalpando, Carlos Y.; Morfopoulos, Arin C.

    2011-01-01

    High precision SAD5 stereo computations can be performed in an FPGA (field-programmable gate array) at much higher speeds than possible in a conventional CPU (central processing unit), but this uses large amounts of FPGA resources that scale with image size. Of the two key resources in an FPGA, Slices and BRAM (block RAM), Slices scale linearly in the new algorithm with image size, and BRAM scales quadratically with image size. An approach was developed to trade latency for BRAM by sub-windowing the image vertically into overlapping strips and stitching the outputs together to create a single continuous disparity output. In stereo, the general rule of thumb is that the disparity search range must be 1/10 the image size. In the new algorithm, BRAM usage scales linearly with disparity search range and scales again linearly with line width. So a doubling of image size, say from 640 to 1,280, would in the previous design be an effective 4 of BRAM usage: 2 for line width, 2 again for disparity search range. The minimum strip size is twice the search range, and will produce an output strip width equal to the disparity search range. So assuming a disparity search range of 1/10 image width, 10 sequential runs of the minimum strip size would produce a full output image. This approach allowed the innovators to fit 1280 960 wide SAD5 stereo disparity in less than 80 BRAM, 52k Slices on a Virtex 5LX330T, 25% and 24% of resources, respectively. Using a 100-MHz clock, this build would perform stereo at 39 Hz. Of particular interest to JPL is that there is a flight qualified version of the Virtex 5: this could produce stereo results even for very large image sizes at 3 orders of magnitude faster than could be computed on the PowerPC 750 flight computer. The work covered in the report allows the stereo algorithm to run on much larger images than before, and using much less BRAM. This opens up choices for a smaller flight FPGA (which saves power and space), or for other algorithms

  17. The Pleasures of Sad Music: A Systematic Review

    Matthew eSachs

    2015-07-01

    Full Text Available Sadness is generally seen as a negative emotion, a response to distressing and adverse situations. In an aesthetic context, however, sadness is often associated with some degree of pleasure, as suggested by the ubiquity and popularity, throughout history, of music, plays, films and paintings with a sad content. Here, we focus on the fact that music regarded as sad is often experienced as pleasurable. Compared to other art forms, music has an exceptional ability to evoke a wide-range of feelings and is especially beguiling when it deals with grief and sorrow. Why is it, then, that while human survival depends on preventing painful experiences, mental pain often turns out to be explicitly sought through music? In this article we consider why and how sad music can become pleasurable. We offer a framework to account for how listening to sad music can lead to positive feelings, contending that this effect hinges on correcting an ongoing homeostatic imbalance. Sadness evoked by music is found pleasurable (1 when it is perceived as non-threatening; (2 when it is aesthetically pleasing; and (3 when it produces psychological benefits such as mood regulation, and empathic feelings, caused, for example, by recollection of and reflection on past events. We also review neuroimaging studies related to music and emotion and focus on those that deal with sadness. Further exploration of the neural mechanisms through which stimuli that usually produce sadness can induce a positive affective state could help the development of effective therapies for disorders such as depression, in which the ability to experience pleasure is attenuated.

    Sulfur SAD phasing facilitates the structure determination of diverse native proteins using femtosecond X-rays from free-electron lasers via serial femtosecond crystallography. Serial femtosecond crystallography (SFX) allows structures to be determined with minimal radiation damage. However, phasing native crystals in SFX is not very common. Here, the structure determination of native lysozyme from single-wavelength anomalous diffraction (SAD) by utilizing the anomalous signal of sulfur and chlorine at a wavelength of 1.77 Å is successfully demonstrated. This sulfur SAD method can be applied to a wide range of proteins, which will improve the determination of native crystal structures.

    hydrological ensemble, allowing a noticeable improvement of reliability and performance of ensemble forecasts. The inter-comparison of the two dressing models shows that the SAD model approach does not sufficiently take the hydrological dynamic of the watershed and processes into consideration, i.e. sample heterogeneity. For a same streamflow range corresponds different processes such as rising limbs or recessions, where uncertainties differ, both in terms of bias, magnitude and variability. When compared in details, the dynamical approach reduces the confidence intervals during recessions where uncertainty is relatively lower and slightly increases the confidence intervals during rising limbs or snowmelt periods where uncertainty is greater. SAD and DAD post-processing approaches meets forecasters experiences in terms of representation of hydro-meteorological forecast uncertainties. Hence, we believe that DAD approach allows to improve forecasters analyses and communication of uncertainties to end-users, since DAD concepts better tracks the source of uncertainties.

    Full Text Available Abstract Sternal dehiscence is a serious complication after cardiac surgery. Sternal refixation, performed by simple rewiring or techniqual modification of rewiring as described by Robicsek, can fail, overall when the bone quality is poor or the sternum is completely destroyed. The sternal closure systems, consisting of plates, screws or rib clips and titanium bars, have been recently introduced to treat the complicated sternal dehiscence. We describe for the first time the use of the Strasbourg Thoracic Osteosyntheses System (STRATOS and the greater omentum, to treat a complicated sternal dehiscence, causing chest pain and respiratory failure.

    2016-11-01

    The aim of the current study was to investigate the effects of reappraisal, acceptance, and rumination for regulating anger and sadness on decision-making. Participants (N = 165) were asked to recall two autobiographical events in which they felt intense anger and sadness, respectively. Participants were then instructed to reappraise, accept, ruminate, or not use any strategies to regulate their feelings of anger and sadness. Following this manipulation, risk aversion, and decision-making strategies were measured using a computer-based measure of risk-taking and a simulated real-life decision-making task. Participants who were instructed to reappraise their emotions showed the least anger and sadness, the most adaptive decision-making strategies, but the least risk aversion as compared to the participants in the other conditions. These findings suggest that emotion regulation strategies of negative affective states have an immediate effect on decision-making and risk-taking behaviors.

    Emotional and olfactory processing is frequently shown to be closely linked both anatomically and functionally. Depression, a disease closely related to the emotional state of sadness, has been shown to be associated with a decrease in olfactory sensitivity. The present study focuses on the state of sadness in n = 31 healthy subjects in order to investigate the specific contribution of this affective state in the modulation of olfactory processing. A sad or indifferent affective state was induced using 2 movies that were presented on 2 separate days. Afterward, chemosensory-evoked potentials were recorded after stimulation with an unpleasant (hydrogen sulfide: "rotten eggs") or a pleasant (phenyl ethyl alcohol: "rose") odorant. Latencies of N1 and P2 peaks were longer after induction of the sad affective state. Additionally, amplitudes were lower in a sad affective state when being stimulated with the unpleasant odorant. Processing of olfactory input has thus been reduced under conditions of the sad affective state. We argue that the affective state per se could at least partially account for the reduced olfactory sensitivity in depressed patients. To our knowledge, the present study is the first to show influence of affective state on chemosensory event-related potentials. (PsycINFO Database Record

    2013-06-01

    Full Text Available Cochlear implants have enabled many congenitally or prelingually deaf children to acquire their native language and communicate successfully on the basis of electrical rather than acoustic input. Nevertheless, degraded spectral input provided by the device reduces the ability to perceive emotion in speech. We compared the vocal imitations of 5- to 7-year-old deaf children who were highly successful bilateral implant users with those of a control sample of children who had normal hearing. First, the children imitated several happy and sad sentences produced by a child model. When adults in Experiment 1 rated the similarity of imitated to model utterances, ratings were significantly higher for the hearing children. Both hearing and deaf children produced poorer imitations of happy than sad utterances because of difficulty matching the greater pitch modulation of the happy versions. When adults in Experiment 2 rated electronically filtered versions of the utterances, which obscured the verbal content, ratings of happy and sad utterances were significantly differentiated for deaf as well as hearing children. The ratings of deaf children, however, were significantly less differentiated. Although deaf children’s utterances exhibited culturally typical pitch modulation, their pitch modulation was reduced relative to that of hearing children. One practical implication is that therapeutic interventions for deaf children could expand their focus on suprasegmental aspects of speech perception and production, especially intonation patterns.

    Managing stairs is a challenging activity of daily living (ADL) for older people. This study aims to examine the association between visual impairment and difficulty in managing stairs among older people living alone and those living with others. A population-based cross sectional study was conducted in rural Malaysia from 2007 till 2008. Seven hundred and sixty five older people aged 60 years and over underwent eye examination for visual impairment. Visual acuity criteria were used to define visual impairment. Presenting visual acuity was assessed using a standard metric Snellen Chart of E type. Difficulty in managing stairs was measured according to a question drawn from the Barthel Index which asks "do you need help in climbing stairs". Overall, the prevalence of difficulty in managing stairs among older people in our population was 135 (18.3%, 95% CI 15.7-21.2). After adjusting for important confounders the odds ratio (OR) for visual impairment and difficulty in managing stairs among older people living alone was 5.04 (95% CI 2.27, 10.62). Among older people living with others, the adjusted OR for visual impairment and difficulty in managing stairs was 3.10 (95% CI 1.52, 6.80). In a sample of older people aged 60 years and over, those living alone with visual impairment had greater difficulty in managing stairs than those living with others. Identification of these groups of older people is useful for targeting interventions. Copyright © 2012 Elsevier Inc. All rights reserved.

    We present a novel study on the role of gender in perceptions of and emotions about in-group social image among American Muslims. Two hundred and five (147 females, 58 males) American Muslims completed a questionnaire on how Muslims feel in U.S. society. The study measured both stereotypical (i.e., ‘frightening,’ ‘oppressed’) as well as non-stereotypical in-group social images (i.e., ‘powerful,’ ‘honorable’). In particular, participants were asked how much they believe Muslims are seen as ‘frightening,’ ‘oppressed,’ ‘honorable,’ and ‘powerful’ in U.S. society, and how much anger and sadness they feel about the way U.S. society views Muslims. Participants believed Muslims are seen in stereotypical ways (i.e., as ‘frightening’ and ‘oppressed’) more than in non-stereotypical ways (i.e., as ‘powerful’ and ‘honorable’). Moreover, perceived in-group social image as ‘powerful’ or ‘honorable’ did not predict the intensity of felt anger or sadness. In contrast, the more participants believed Muslims are seen as ‘frightening,’ the more intense their anger and sadness. Furthermore, responses to perceived social image as ‘oppressed’ were moderated by gender. American Muslim female participants believed that Muslims are seen as ‘oppressed’ in U.S. society to a greater extent than male participants did. In addition, perceived social image as ‘oppressed’ only predicted anger for female participants: the more female participants believed Muslims are seen as ‘oppressed,’ the more intense their anger. This study contributes to the scarce literature on American Muslims in psychology, and shows that both anger and sadness are relevant to the study of perceived social image. PMID:28123374

  10. Natural Recharge to the Unconfined Aquifer System on the Hanford Site from the Greater Cold Creek Watershed: Progress Report 2004

    Movement of contaminants in groundwater at the Hanford Site is heavily dependent on recharge to the unconfined aquifer. As the effects of past artificial discharges dissipate, the water table is expected to return to more natural conditions, and natural recharge will become the driving force when evaluating future groundwater flow conditions and related contaminant transport. Previous work on the relationship of natural recharge to groundwater movement at the Hanford Site has focused on direct recharge from infiltrating rainfall and snowmelt within the area represented by the Sitewide Groundwater Model (SGM) domain. However, part of the groundwater recharge at Hanford is provided by flow from Greater Cold Creek watershed (GCC), a large drainage area on the western boundary of the Hanford Site that includes Cold Creek Valley, Dry Creek Valley, and the Hanford side of Rattlesnake Mountain. This study was undertaken to estimate the recharge from GCC, which is believed to enter the unconfined aquifer as both infiltrating streamflow and shallow subsurface flow. To estimate recharge, the Distributed Hydrology-Soil-Vegetation Model (DHSVM) was used to simulate a detailed water balance of GCC from 1956 to 2001 at a spatial resolution of 200~m and a temporal resolution of one hour. For estimating natural recharge to Hanford from watersheds along its western and southwestern boundaries, the most important aspects that need to be considered are 1)~distribution and relative magnitude of precipitation and evapotranspiration over the watershed, 2)~streamflow generation at upper elevations and infiltration at lower elevations during rare runoff events, and 3)~permeability of the basalt bedrock surface underlying the soil mantle.

    Full Text Available A recent study has reported that the successful implementation of cognitive regulation of emotion depends on higher-level cognitive functions, such as top-down control, which may be impaired in stressful situations. This calls for a need of cognition free self-regulatory strategies that do not require top-down control. In contrast to the cognitive regulation of emotion that emphasizes the role of cognition, traditional Chinese philosophy and medicine views the relationship among different types of emotions as promoting or counteracting each other, without the involvement of cognition, which provides an insightful perspective for developing cognition free regulatory strategies. In this study, we examined two hypotheses regarding the modulation of anger and aggressive behavior: sadness counteracts anger or aggressive behavior, whereas fear promotes anger or aggressive behavior. Participants were first provoked by reading the extremely negative feedback on their viewpoints (Study 1 or by watching anger-inducing movie clips (Study 2; then, these angry participants were assigned to three equivalent groups and view sad, fear, or neutral materials respectively to evoke the corresponding emotions. The results found participants yielded a lower level of aggressive behavior when sadness was induced afterward, and a higher level of anger when fear was induced afterward. These results provided evidence supporting the hypothesis of mutual promotion or counteraction relationships among these types of emotion and implied a cognition free approach for regulating anger and aggressive behavior.

    Full Text Available The present essay begins, in its first section, with a mention of the wealth of beautiful thoughts that Amoris Laetitia (AL enriches us with, and of the wonderful core of the message of AL, the merciful love of God for every human being expressed in the words of Christ cited above. It then concentrates on a small portion of the assertions of AL, but which are likely to have the strongest effect and give cause for concern and sadness.The second part concerns the question who the couples in “irregular situations” are, to whom AL wants to grant access to the sacraments, and whether admitting them (without repentance and will to change their life to sacramental absolution of sins and Eucharist is compatible with the Gospel, Church doctrine and human reason. Four fundamentally different answers that dominate the current discussion as to who these couples admitted to the sacraments are according to AL are discussed critically, to show that a clear statement about which of them is true and which are blatantly false, desperately is needed to avert chaos: No “irregular couples” at all? All “irregular couples”? Some, carefully examined, couples in irregular situations?“Irregular couples” who have not celebrated marriage in the Church but only entered a “marriage of conscience,” which AL for the first time in the history of the Church permits and recognizes?Since the second reply authorizes any sacrilege and transforms the holy Temple of God into a temple of Satan, this reply cannot be the one the Pope intends to give. But as it is nonetheless proposed by high dignitaries in the Church and the Pope has remained silent about it, it seems necessary to break this silence and to reject this second blasphemous response in the sharpest possible terms.The third answer is most likely the one meant by Francis. It asserts that the couples admitted to the sacraments must be subjected to a thorough discernment in order to see whether they are so

    1. Biventricular hypertrophy has been described in a high blood pressure variability (BPV) model of sinoaortic-denervated (SAD) rats without systemic hypertension. To explore the possible involvement of the lung in SAD-induced right ventricular hypertrophy (RVH), we examined lung morphology, in addition to systemic haemodynamics and ventricle morphology, in Wistar-Kyoto rats 32 weeks after SAD. 2. In Wistar-Kyoto rats 32 weeks after SAD, there existed a substantial elevation in BPV, with no change in the average level of arterial pressure. Biventricular hypertrophy following SAD was characterized by a greater hypertrophy in right than left ventricles; both absolute and normalized right ventricular weights were significantly increased by 22 and 27%, respectively, and only normalized left ventricular weight was significantly increased by 12%. No infarcts were found in any ventricles examined. 3. In the lung, the most prominent change following SAD was pulmonary vasculopathy, including wall thickening, perivascular fibrosis and cell infiltration. In pulmonary arteries with an internal diameter of 70-130 microm, the external diameter, wall thickness and wall thickness to internal diameter ratio were increased in SAD compared with control rats. 4. There was no correlation between right and left ventricular weights. In contrast with BPV-correlated left ventricular weight, right ventricular weight was correlated with the wall thickness of the pulmonary artery, but not with BPV. 5. These findings suggest that greater RVH following SAD is associated with pulmonary vasculopathy, but is not secondary to the left ventricular problems or high BPV.

  14. The Pleasure Evoked by Sad Music Is Mediated by Feelings of Being Moved

    Why do we enjoy listening to music that makes us sad? This question has puzzled music psychologists for decades, but the paradox of “pleasurable sadness” remains to be solved. Recent findings from a study investigating the enjoyment of sad films suggest that the positive relationship between felt sadness and enjoyment might be explained by feelings of being moved (Hanich et al., 2014). The aim of the present study was to investigate whether feelings of being moved also mediated the enjoyment of sad music. In Experiment 1, 308 participants listened to five sad music excerpts and rated their liking and felt emotions. A multilevel mediation analysis revealed that the initial positive relationship between liking and felt sadness (r = 0.22) was fully mediated by feelings of being moved. Experiment 2 explored the interconnections of perceived sadness, beauty, and movingness in 27 short music excerpts that represented independently varying levels of sadness and beauty. Two multilevel mediation analyses were carried out to test competing hypotheses: (A) that movingness mediates the effect of perceived sadness on liking, or (B) that perceived beauty mediates the effect of sadness on liking. Stronger support was obtained for Hypothesis A. Our findings suggest that – similarly to the enjoyment of sad films – the aesthetic appreciation of sad music is mediated by being moved. We argue that felt sadness may contribute to the enjoyment of sad music by intensifying feelings of being moved. PMID:28377740

    Full Text Available Abstract Background Recent research has emphasized that the human circadian rhythm system is differentially sensitive to short wavelength light. Light treatment devices using efficient light-emitting diodes (LEDs whose output is relatively concentrated in short wavelengths may enable a more convenient effective therapy for Seasonal Affective Disorder (SAD. Methods The efficacy of a LED light therapy device in the treatment of SAD was tested in a randomized, double-blind, placebo-controlled, multi-center trial. Participants aged 18 to 65 with SAD (DSM-IV major depression with seasonal pattern were seen at Baseline and Randomization visits separated by 1 week, and after 1, 2, 3 and 4 weeks of treatment. Hamilton Depression Rating Scale scores (SIGH-SAD were obtained at each visit. Participants with SIGH-SAD of 20 or greater at Baseline and Randomization visits were randomized to active or control treatment: exposure to the Litebook LED treatment device (The Litebook Company Ltd., Alberta, Canada which delivers 1,350 lux white light (with spectral emission peaks at 464 nm and 564 nm at a distance of 20 inches or to an inactivated negative ion generator at a distance of 20 inches, for 30 minutes a day upon awakening and prior to 8 A.M. Results Of the 26 participants randomized, 23 completed the trial. Mean group SIGH-SAD scores did not differ significantly at randomization. At trial end, the proportions of participants in remission (SIGH-SAD less than 9 were significantly greater (Fisher's exact test, and SIGH-SAD scores, as percent individual score at randomization, were significantly lower (t-test, with active treatment than with control, both in an intent-to-treat analysis and an observed cases analysis. A longitudinal repeated measures ANOVA analysis of SIGH-SAD scores also indicated a significant interaction of time and treatment, showing superiority of the Litebook over the placebo condition. Conclusion The results of this pilot study support

    Empathy has been associated with decreased antisocial and increased prosocial behavior. This study examined empathy and prosocial behavior in response to sadness and distress in disruptive behavior disorder (DBD) and attention-deficit hyperactivity disorder (ADHD). Six- and 7-year-old children with DBD (with and without ADHD) (n = 67) and with ADHD only (n = 27) were compared to typically developing children (TD) (n = 37). Parents and teachers rated affective empathy in response to sadness and distress on the Griffith Empathy Measure. Children reported affective empathic ability in response to sad story vignettes. Empathy-induced prosocial behavior in response to sadness and distress was assessed with a computer task, the Interpersonal Response Task (IRT). Compared to TD, children with DBD (with and without ADHD) and those with ADHD only were rated as less empathic by their teachers, but not by their parents. No differences between groups were observed in children who reported affect correspondence. Children with DBD (with and without ADHD) showed less prosocial behavior in response to sadness and distress compared to TD. Children with ADHD only did not differ from TD. An additional analysis comparing all children with a diagnosis to the TD group revealed that the difference in prosocial behavior remained after controlling for ADHD symptoms, but not after controlling for DBD symptoms. These findings of impaired empathy-induced prosocial behavior in response to sadness and distress in young children with DBD suggest that interventions to ameliorate peer relationships may benefit from targeting on increasing prosocial behavior in these children.

  17. Yoga Meditation Practitioners Exhibit Greater Gray Matter Volume and Fewer Reported Cognitive Failures: Results of a Preliminary Voxel-Based Morphometric Analysis

    Full Text Available Hatha yoga techniques, including physical postures (asanas, breathing exercises (pranayama, and meditation, involve the practice of mindfulness. In turn, yoga meditation practices may induce the state of mindfulness, which, when evoked recurrently through repeated practice, may accrue into trait or dispositional mindfulness. Putatively, these changes may be mediated by experience-dependent neuroplastic changes. Though prior studies have identified differences in gray matter volume (GMV between long-term mindfulness practitioners and controls, no studies to date have reported on whether yoga meditation is associated with GMV differences. The present study investigated GMV differences between yoga meditation practitioners (YMP and a matched control group (CG. The YMP group exhibited greater GM volume in frontal, limbic, temporal, occipital, and cerebellar regions; whereas the CG had no greater regional greater GMV. In addition, the YMP group reported significantly fewer cognitive failures on the Cognitive Failures Questionnaire (CFQ, the magnitude of which was positively correlated with GMV in numerous regions identified in the primary analysis. Lastly, GMV was positively correlated with the duration of yoga practice. Results from this preliminary study suggest that hatha yoga practice may be associated with the promotion of neuroplastic changes in executive brain systems, which may confer therapeutic benefits that accrue with repeated practice.

    Full Text Available We provide systematic evidence for the range and importance of hedonic reversals as a major source of pleasure, and incorporate these findings into the theory of benign masochism. Twenty-nine different initially aversive activities are shown to produce pleasure (hedonic reversals in substantial numbers of individuals from both college student and Mechanical Turk samples. Hedonic reversals group, by factor analysis, into sadness, oral irritation, fear, physical activity/exhaustion, pain, strong alcohol-related tastes, bitter tastes, and disgust. Liking for sad experiences (music, novels, movies, paintings forms a coherent entity, and is related to enjoyment of crying in response to sad movies. For fear and oral irritation, individuals also enjoy the body's defensive reactions. Enjoyment of sadness is higher in females across domains. We explain these findings in terms of benign masochism, enjoyment of negative bodily reactions and feelings in the context of feeling safe, or pleasure at ``mind over body''. In accordance with benign masochism, for many people, the favored level of initially negative experiences is just below the level that cannot be tolerated.

    The mechanism of music effects on pain perception remains to be elucidated. To determine which component (mood or valence) of music is more important in music-induced hypoalgesia, we compared the effects of 2 melodies with different moods (happy vs sad) but with the same degree of valence (pleasant vs unpleasant) to an affective neutral lecture and a control (baseline) on the objective and subjective responses to tonic heat pain. Our hypothesis was that if mood was the key component, the happy melody would reduce pain, whereas the sad one would exacerbate pain; and if valence is the key component, the 2 melodies would both alleviate pain. Twenty females participated in this study which consisted of 4 conditions (baseline, happy melody, sad melody, and lecture). Pain tolerance time (PTT), pain intensity, and distress dynamics and the characteristics of pain were measured. A newly devised multiple affective rating scale (MARS) was employed to assess the subjective experience of auditory perception. Both happy and sad melodies of equal valence resulted in significant lower pain ratings during the pain test and were in contrast to the mood prediction. These results indicate that the valence of music, rather than the mood it induced, appears to be the most likely mediator of the hypoalgesic effect of the different music. This article provides new evidence that the valence of music is more crucial than mood in affective pain modulation. This finding gives impetus for health professionals to manage pain more effectively in patients with proper music.

    The glucocorticoid hormone cortisol is known to have wide-ranging effects on a variety of physiological systems, including the morphology and physiology of the amygdala and hippocampus. Disruptions of cortisol regulation and signaling are also linked with psychiatric disorders involving emotional disturbances. Although there is much evidence to suggest a relationship between cortisol signaling and the brain physiology underlying emotion, few studies have attempted to test for direct effects of cortisol on the neurophysiology of emotion. We administered exogenous synthetic cortisol (hydrocortisone, HCT) using two different dosing regimens (25 mg/day over 4 days, 100 mg single dose), in a double-blind placebo-controlled functional magnetic resonance imaging (fMRI) study. During fMRI scanning, healthy subjects viewed images designed to induce happy, sad, and neutral emotional states. Subjective emotional reactions were collected for each experimental stimulus after fMRI scanning. Mood ratings were also collected throughout the 4 days of the study. Both dose regimens of HCT resulted in decreased subgenual cingulate activation during sadness conditions. The 25 mg/day regimen also resulted in higher arousal ratings of sad stimuli. No effects of HCT were observed on any mood ratings. Few reliable effects of HCT were observed on brain activity patterns or subjective emotional responses to stimuli that were not sad. The inhibitory effects of cortisol on sadness-induced subgenual cingulate activity may have critical relevance to the pathophysiology of major depression, as both subgenual hyperactivity and decreased sensitivity to cortisol signaling have been documented in patients with depression.

    Full Text Available The paradox of enjoying listening to music that evokes sadness is yet to be fully understood. Unlike prior studies that have explored potential explanations related to lyrics, memories, and mood regulation, we investigated the types of emotions induced by unfamiliar, instrumental sad music, and whether these responses are consistently associated with certain individual difference variables. One hundred and two participants were drawn from a representative sample to minimise self-selection bias. The results suggest that the emotional responses induced by unfamiliar sad music could be characterized in terms of three underlying factors: Relaxing sadness, Moving sadness, and Nervous sadness. Relaxing sadness was characterized by felt and perceived peacefulness and positive valence. Moving sadness captured an intense experience that involved feelings of sadness and being moved. Nervous sadness was associated with felt anxiety, perceived scariness and negative valence. These interpretations were supported by indirect measures of felt emotion. Experiences of Moving sadness were strongly associated with high trait empathy and emotional contagion, but not with other previously suggested traits such as absorption or nostalgia-proneness. Relaxing sadness and Nervous sadness were not significantly predicted by any of the individual difference variables. The findings are interpreted within a theoretical framework of embodied emotions.

    This essay chooses as its texts three films representing contemporary gay male subjects from each of the "three" China's: HK, Taiwan, and the Mainland. Relocating the homoerotic image of the "sad young man," a trope popular from Hollywood rebellion films of the 1950s and 1960s, to contemporary China, I discuss how this masculine icon has been transformed from one of heroic rebellion to one of existential isolation. Indeed, as the politics of both the outmoded Confucian family and fractured Chinese nationhood intersect, what the sad young (gay) man rebels against is a political fluctuation which is no longer fixed; as the young man's opposition is no longer fixed, so too does he become alienated even from his own rebellious cause.

    Multilevel models of developmental psychopathology implicate both characteristics of the individual and their rearing environment in the etiology of internalizing problems and disorders. Maladaptive regulation of fear and sadness, the core of anxiety and depression, arises from the conjoint influences of ineffective parasympathetic regulation of emotion and ineffective emotion socialization experiences. In 171 youths (84 female, M = 13.69 years, SD = 1.84), we measured changes of respiratory sinus arrhythmia (RSA) in response to sadness- and fear-inducing film clips and maternal supportive and punitive responses to youths' internalizing emotions. Youths and mothers reported on youths' internalizing problems and anxiety and depression symptoms concurrently and 2 years later at Time 2. Maternal supportive emotion socialization predicted fewer, and punitive socialization predicted more, mother-reported internalizing problems at Time 2 only for youths who showed RSA suppression to fear-inducing films. More RSA suppression to sadness-inducing films predicted more youth-reported internalizing problems at Time 2 in girls only. In addition, less supportive emotion socialization predicted more youth-reported depression symptoms at Time 2 only for girls who showed more RSA suppression to sadness. RSA suppression to sadness versus fear might reflect different patterns of atypical parasympathetic regulation of emotional arousal, both of which increase the risk for internalizing difficulties in youths, and especially girls, who lack maternal support for regulating emotions.

    Full Text Available Although the body weight evaluation (e.g., normal or overweight of others relies on perceptual impressions, it also can be influenced by other psychosocial factors. In this study, we explored the effect of task-irrelevant emotional facial expressions on judgments of body weight and the relationship between emotion-induced weight judgment bias and other psychosocial variables including attitudes towards obese person. Forty-four participants were asked to quickly make binary body weight decisions for 960 randomized sad and neutral faces of varying weight levels presented on a computer screen. The results showed that sad facial expressions systematically decreased the decision threshold of overweight judgments for male faces. This perceptual decision bias by emotional expressions was positively correlated with the belief that being overweight is not under the control of obese persons. Our results provide experimental evidence that task-irrelevant emotional expressions can systematically change the decision threshold for weight judgments, demonstrating that sad expressions can make faces appear more overweight than they would otherwise be judged.

    The serine/threonine kinase SAD regulates neural functions such as axon/dendrite polarization and neurotransmitter release. In the vertebrate central nervous system, SAD-B, a homolog of Caenorhabditis elegans SAD-1, is associated with synaptic vesicles and the active zone cytomatrix in nerve terminals. However, the distribution of SAD-B in the peripheral nervous system remains elusive. Here, we show that SAD-B is specifically localized to neuromuscular junctions. Although the active zone protein bassoon showed a punctated signal indicating its localization to motor end plates, SAD-B shows relatively diffuse localization indicating its association with both the active zone and synaptic vesicles. Therefore, SAD kinase may regulate neurotransmitter release from motor end plates in a similar manner to its regulation of neurotransmitter release in the central nervous system.

  12. Sad mood increases pain sensitivity upon thermal grill illusion stimulation: implications for central pain processing.

    In different fields of neuroscience research, illusions have successfully been used to unravel underlying mechanisms of stimulus processing. One such illusion existing for the field of pain research is the so-called thermal grill illusion. Here, painful sensations are elicited by interlacing warm and cold bars, with stimulus intensities (temperatures) of these bars being below the respective heat pain or cold pain thresholds. To date, the underlying mechanisms of this phenomenon are not completely understood. There is some agreement, however, that the sensation evoked by this stimulation is generated by central nervous interactions. Therefore, we followed two approaches in this study: firstly, we aimed at developing and validating a water-driven device which might be used in fMRI scanners in future studies - subject to minor adaptations. Secondly, we aimed to interfere with this illusion by induction of a sad mood state, a procedure which is suggested to influence central nervous structures that are also involved in pain processing. The newly developed device induced thermal grill sensations similar to those reported in the literature. Induction of sad, but not neutral mood states, resulted in higher pain and unpleasantness ratings of the painful illusion. These findings might be of importance for the understanding of pain processing in healthy volunteers, but putatively even more so in patients with major depressive disorder. Moreover, our results might indicate that central nervous structures involved in the affective domain or cognitive domain of pain processing might be involved in the perception of the illusion.

    Background Following a legal agreement with the European Union (EU), Philip Morris International (PMI) commissions a yearly report (‘Project Star’, PS) on the European illicit cigarette trade from KPMG, the global accountancy firm. Methods Review of PS 2010 report. Comparison with data from independent sources including a 2010 pan-European survey (N=18 056). Findings Within PS, data covering all 27 EU countries are entered into a model. While the model itself seems appropriate, concerns are identified with the methodologies underlying the data inputs and thus their quality: there is little transparency over methodologies; interview data underestimate legal non-domestic product partly by failing to account for legal cross-border sales; illicit cigarette estimates rely on tobacco industry empty pack surveys which may overestimate illicit; and there is an over-reliance on data supplied by PMI with inadequate external validation. Thus, PMI sales data are validated using PMI smoking prevalence estimates, yet PMI is unable to provide sales (shipment) data for the Greek islands and its prevalence estimates differ grossly from independent data. Consequently, comparisons with independent data suggest PS will tend to overestimate illicit cigarette levels particularly where cross-border shopping is frequent (Austria, Finland, France) and in Western compared with Eastern European countries. The model also provides data on the nature of the illicit cigarette market independent of seizure data suggesting that almost a quarter of the illicit cigarette market in 2010 comprised PMI's own brands compared with just 5% counterfeited PMI brands; a finding hidden in PMI's public representation of the data. Conclusions PS overestimates illicit cigarette levels in some European countries and suggests PMI's supply chain control is inadequate. Its publication serves the interests of PMI over those of the EU and its member states. PS requires greater transparency, external scrutiny and

    Recent research revealed that emotional content can be successfully decoded from human dance movement. Most previous studies made use of videos of actors or dancers portraying emotions through choreography. The current study applies emotion induction techniques and free movement in order to examine the recognition of emotional content from dance. Observers (N = 30) watched a set of silent videos showing depersonalized avatars of dancers moving to an emotionally neutral musical stimulus after emotions of either sadness or happiness had been induced. Each of the video clips consisted of two dance performances which were presented side-by-side and were played simultaneously; one of a dancer in the happy condition and one of the same individual in the sad condition. After every film clip, the observers were asked to make forced-choices concerning the emotional state of the dancer. Results revealed that observers were able to identify the emotional state of the dancers with a high degree of accuracy. Moreover, emotions were more often recognized for female dancers than for their male counterparts. In addition, the results of eye tracking measurements unveiled that observers primarily focus on movements of the chest when decoding emotional information from dance movement. The findings of our study show that not merely portrayed emotions, but also induced emotions can be successfully recognized from free dance movement.

    The worldwide fascination of da Vinci’s Mona Lisa has been dedicated to the emotional ambiguity of her face expression. In the present study we manipulated Mona Lisa’s mouth curvature as one potential source of ambiguity and studied how a range of happier and sadder face variants influences perception. In two experimental conditions we presented different stimulus ranges with different step sizes between stimuli along the happy-sad axis of emotional face expressions. Stimuli were presented in random order and participants indicated the perceived emotional face expression (first task) and the confidence of their response (second task). The probability of responding ‘happy’ to the original Mona Lisa was close to 100%. Furthermore, in both conditions the perceived happiness of Mona Lisa variants described sigmoidal functions of the mouth curvature. Participants’ confidence was weakest around the sigmoidal inflection points. Remarkably, the sigmoidal functions, as well as confidence values and reaction times, differed significantly between experimental conditions. Finally, participants responded generally faster to happy than to sad faces. Overall, the original Mona Lisa seems to be less ambiguous than expected. However, perception of and reaction to the emotional face content is relative and strongly depends on the used stimulus range. PMID:28281547

    Background Streptococcus suis is a zoonotic pathogen, causing meningitis and septicemia. We previously demonstrated that the gastrointestinal tract (GIT) is an entry site for zoonotic S. suis infection. Here we studied the contribution of Streptococcal adhesin Protein (SadP) to host-pathogen interaction at GIT level. Methods SadP expression in presence of Intestinal Epithelial Cells (IEC) was compared with expression of other virulence factors by measuring transcript levels using quantitative Real Time PCR (qRT-PCR). SadP variants were identified by phylogenetic analysis of complete DNA sequences. The interaction of SadP knockout and complementation mutants with IEC was tested in vitro. Results Expression of sadP was significantly increased in presence of IEC. Sequence analysis of 116 invasive strains revealed five SadP sequence variants, correlating with genotype. SadP1, present in zoonotic isolates of clonal complex 1, contributed to binding to both human and porcine IEC and translocation across human IEC. Antibodies against the globotriaosylceramide Gb3/CD77 receptor significantly inhibited adhesion to human IEC. Conclusion SadP is involved in the host-pathogen interaction in the GIT. Differences between SadP variants may determine different affinities to the Gb3/CD77 host-receptor, contributing to variation in adhesion capacity to host IEC and thus to S. suis zoonotic potential.

    Greater trochanteric pain is one of the common complaints in orthopedics. Frequent diagnoses include myofascial pain, trochanteric bursitis, tendinosis and rupture of the gluteus medius and minimus tendon, and external snapping hip. Furthermore, nerve entrapment like the piriformis syndrome must be considered in the differential diagnosis. This article summarizes essential diagnostic and therapeutic steps in greater trochanteric pain syndrome. Careful clinical evaluation, complemented with specific imaging studies and diagnostic infiltrations allows determination of the underlying pathology in most cases. Thereafter, specific nonsurgical treatment is indicated, with success rates of more than 90 %. Resistant cases and tendon ruptures may require surgical intervention, which can provide significant pain relief and functional improvement in most cases.

    Providing opportunities for aspirant nurses to obtain pre-nursing experience features prominently in the UK Government's response to The Francis Inquiry. Evidence from the USA suggests that pre-nursing experiences, such as summer camps, have the potential to contribute to effective nurse recruitment, selection and retention strategies. However, few similar pre-nursing experiences exist in the UK, and none have been evaluated. This paper reports the experiences of participation in a pilot pre-nursing scholarship among secondary school pupils in Scotland. To explore pupils' experiences of a pre-nursing scholarship to inform future design and delivery of similar programmes in the UK and internationally. Qualitative focus group study. Two university campuses in Scotland. Twenty-two secondary school students (all female, aged 15-18 years). Two focus groups were facilitated through the use of 'anecdote circles' to elicit pupils' stories of their scholarship experience. Anecdote circles allowed each pupil to share their story in turn and then collectively assemble, figuratively and physically through interlocking written cards, shared stories of the scholarship. Discussions were audio recorded and transcribed verbatim. Data were analysed thematically. Three stories emerged: 1) sadness; 2) socialisation; and, 3) shifted perceptions. Sad stories were transformative affirming the pupils' desire to become a nurse. Stories of socialisation revealed how demonstrating practical skills affirmed the pupils' ability and suitability to nurse. Perceptions of the life and work of a (student) nurse, their future career, and the lives of older adults, shifted through the scholarship, especially during practice learning experience. Storytelling revealed how a pre-nursing scholarship helped secondary school pupils to decide whether to pursue a nursing career by providing an opportunity to explore their ability, suitability and desire for nursing. The practice learning experience emerged

    Full Text Available Motion estimation is a very important but computationally complex task in video coding. Process of determining motion vectors based on the temporal correlation of consecutive frame is used for video compression. In order to reduce the computational complexity of motion estimation and maintain the quality of encoding during motion compensation, different fast search techniques are available. These block based motion estimation algorithms use the sum of absolute difference (SAD between corresponding macroblock in current frame and all the candidate macroblocks in the reference frame to identify best match. Existing implementations can perform SAD between two blocks using sequential or pipeline approach but performing multi operand SAD in single clock cycle with optimized recourses is state of art. In this paper various parallel architectures for computation of the fixed block size SAD is evaluated and fast parallel SAD architecture is proposed with optimized resources. Further SAD processor is described with 9 processing elements which can be configured for any existing fast search block matching algorithm. Proposed SAD processor consumes 7% fewer adders compared to existing implementation for one processing elements. Using nine PE it can process 84 HD frames per second in worse case which is good outcome for real time implementation. In average case architecture process 325 HD frames per second.

    Hunter, Sally; Arendt, Thomas; Brayne, Carol

    2013-12-01

    Alzheimer disease (AD) is a progressive, neurodegenerative disease characterised in life by cognitive decline and behavioural symptoms and post-mortem by the neuropathological hallmarks including the microtubule-associated protein tau-reactive tangles and neuritic plaques and amyloid-beta-protein-reactive senile plaques. Greater than 95 % of AD cases are sporadic (SAD) with a late onset and FAD) with an early onset. FAD is associated with various genetic mutations in the amyloid precursor protein (APP) and the presenilins (PS)1 and PS2. As yet, no disease pathway has been fully accepted and there are no treatments that prevent, stop or reverse the cognitive decline associated with AD. Here, we review and integrate available environmental and genetic evidence associated with all forms of AD. We present the senescence hypothesis of AD progression, suggesting that factors associated with AD can be seen as partial stressors within the matrix of signalling pathways that underlie cell survival and function. Senescence pathways are triggered when stressors exceed the cells ability to compensate for them. The APP proteolytic system has many interactions with pathways involved in programmed senescence and APP proteolysis can both respond to and be driven by senescence-associated signalling. Disease pathways associated with sporadic disease may be different to those involving familial genetic mutations. The interpretation we provide strongly points to senescence as an additional underlying causal process in dementia progression in both SAD and FAD via multiple disease pathways.

    Full Text Available The first subject of research in this article is the review and comparison of various theoretical approaches to marketing applied in institutions of higher education. The authors have observed the marketing as an active process by which institutions of higher education attract their users' attention to the educational services they offer. The research has sought for an answer to the question which marketing mix instrument has the greatest impact on the student decision to enroll at a particular faculty at the University of Novi Sad. The study involved 783 students at six faculties of this university. The authors used a non-standardized survey questionnaire to measure the attitudes towards 26 different marketing tools, using the five-point Likert scale. Principal components factor analysis was used to classify variables. The authors singled out seven factors relevant to the faculty choice: people, physical evidence, promotion, image, resources and extra services, location and price. The results coincided with the traditional elements of marketing mix (7P to a greater or lesser extent, confirming the results of previously conducted studies.

    1993-08-01

    Two studies investigated the role of expressive vocal behavior (specifically, speech rate and loudness) in fear and anxiety and in sadness and depression. In the first study, participants spoke about personally experienced fear and anxiety-arousing and neutral events using 3 different voice styles: fast and loud, normal, and slow and soft. In the second study, participants spoke about personally experienced sad or depressing and neutral events using the same 3 voice styles. In both studies, the participants' highest levels of subjective affective and cardiovascular (CV) arousal occurred when they spoke about the emotional events in a mood-congruent voice style: fast and loud in the case of fear and anxiety, and slow and soft in the case of sadness or depression. Mood-incongruent voice styles canceled the heightened levels of CV arousal normally associated with these negative emotions. The voice-style manipulation had no significant effect on the participants' levels of CV arousal during the neutral discussions.

The subject of this paper are postural disorders on the spinal column in the sagittal and frontal planes, as well as foot deformities. The aim of the research is to determine the frequency of disorder of postural status of the spine (kyphosis, lordosis and scoliosis and deviation from the normal status of the foot, and the analysis of the differences between boys and girls. Assessment of the postural status of the feet was performed by means of using the Pedikom computer system for digital computerised pedography. Assessment of spine postural status was done by means of SpineScan portable device. Data were analysed according to the frequency for the assessment of spinal status, the status of the foot, all according gender. Significance of the gender-conditioned differences was determined by the Chi-square test. The results indicate that in the examined population, the most common posture is lordotic bad posture, 41.31% with male examinees and 36.66% with female examinees. A statistically significant difference in relation to sexual dimorphism was found for the parameter of scoliotic bad posture (Sig. = 0.008. In terms of deviation from the normal status of the feet, in the examined population, pronating foot level I accounts for 43.23%, pronating foot level II accounts for 16.66% and high-arched foot accounts for 10.16%. Quantitative results indicate the need for corrective gymnastic to correct but also prevent postural deformities by introducing of the same as an everyday directed activity of preschool population.

  19. Public acceptance of management actions and judgments of responsibility for the wolves of the southern Greater Yellowstone Area: Report to Grand Teton National Park

    Taylor, Jonathan G.; Johnson, S. Shea; Shelby, Lori B.

    2005-01-01

    Introduction Wolves of Grand Teton National Park and the Greater Yellowstone Area Gray wolves (Canis lupus) appeared in Grand Teton National Park (GRTE) in October of 1998, two years after being reintroduced to Yellowstone National Park (YNP). Since that time, five packs have been within the GRTE borders - Gros Ventre Pack, Nez Perce Pack, Yellowstone Delta Pack, Teton Pack, and Green River Pack (Table 1). Wolves in the Greater Yellowstone Area are increasing and spreading out geographically (USFWS and others, 2004). This dispersion was demonstrated recently by the death of a 2-year-old female wolf from the Swan Lake pack on I-70 in Colorado (June 7, 2004; http://mountain-prairie.USFWS.gov/pressrel /04-43.htm). The organization of wolf packs in the GYA is dynamic and highly structured. In 2003, for example, a wolf from the Teton Pack joined with the Green River Pack, and several young wolves left the Teton Pack and moved south (USFWS and others, 2004). Pack size (averaging five to ten members) is dependent on hunting efficiency, which depends on prey size, type, and density. Each pack defends home ranges of several hundred square miles. The social structure of the pack is based on a breeding pair (an alpha male and female). Other wolves in the pack can be categorized as betas (males and/or females second in rank to the alphas), subordinates, pups, and occasional omegas (outcasts). Because generally only the alpha pair breeds, subordinate wolves of reproductive age must disperse from their packs and form new associations in order to breed. (http://www.nps.gov/grte/wolf/biolo.htm). The reintroduced wolves are classified by the U.S. Fish and Wildlife Service (USFWS) as "nonessential experimental" under section 10(j) of the Endangered Species Act. The recovery criteria for the GYA wolves were met in 2002 for removing the wolves from the Endangered Species List (30 or more breeding pairs). Currently, the USFWS manages wolf populations in the GYA until delisting occurs

    Reactions to memorable experiences of sad music were studied by means of a survey administered to a convenience (N = 1577), representative (N = 445), and quota sample (N = 414). The survey explored the reasons, mechanisms, and emotions of such experiences. Memorable experiences linked with sad music typically occurred in relation to extremely familiar music, caused intense and pleasurable experiences, which were accompanied by physiological reactions and positive mood changes in about a third...

    Emotional faces and scenes carry a wealth of overlapping and distinct perceptual information. Despite widespread use in the investigation of emotional perception, expressive face and evocative scene stimuli are rarely assessed in the same experiment. Here, we evaluated self-reports of arousal and pleasantness, as well as early and late event-related potentials (e.g., N170, early posterior negativity [EPN], late positive potential [LPP]) as subjects viewed neutral and emotional faces and scenes, including contents representing anger, fear, and joy. Results demonstrate that emotional scenes were rated as more evocative than emotional faces, as only scenes produced elevated self-reports of arousal. In addition, viewing scenes resulted in more extreme ratings of pleasantness (and unpleasantness) than did faces. EEG results indicate that both expressive faces and emotional scenes evoke enhanced negativity in the N170 component, while the EPN and LPP components show significantly enhanced modulation only by scene, relative to face stimuli. These data suggest that viewing emotional scenes results in a more pronounced emotional experience that is associated with reliable modulation of visual event-related potentials that are implicated in emotional circuits in the brain.

    Full Text Available PIPE-chipSAD is a pipeline for bacterial transcriptome studies based on high-density microarray experiments. The main algorithm chipSAD, integrates the analysis of the hybridization signal with the genomic position of probes and identifies portions of the genome transcribing for mRNAs. The pipeline includes a procedure, align-chipSAD, to build a multiple alignment of transcripts originating in the same locus in multiple experiments and provides a method to compare mRNA expression across different conditions. Finally, the pipeline includes anno-chipSAD a method to annotate the detected transcripts in comparison to the genome annotation. Overall, our pipeline allows transcriptional profile analysis of both coding and non-coding portions of the chromosome in a single framework. Importantly, due to its versatile characteristics, it will be of wide applicability to analyse, not only microarray signals, but also data from other high throughput technologies such as RNA-sequencing.The current PIPE-chipSAD implementation is written in Python programming language and is freely available at https://github.com/silviamicroarray/chipSAD.

    There is a long history of attempts to explain why music is perceived as expressing emotion. The relationship between pitches serves as an important cue for conveying emotion in music. The musical interval referred to as the minor third is generally thought to convey sadness. We reveal that the minor third also occurs in the pitch contour of speech conveying sadness. Bisyllabic speech samples conveying four emotions were recorded by 9 actresses. Acoustic analyses revealed that the relationship between the 2 salient pitches of the sad speech samples tended to approximate a minor third. Participants rated the speech samples for perceived emotion, and the use of numerous acoustic parameters as cues for emotional identification was modeled using regression analysis. The minor third was the most reliable cue for identifying sadness. Additional participants rated musical intervals for emotion, and their ratings verified the historical association between the musical minor third and sadness. These findings support the theory that human vocal expressions and music share an acoustic code for communicating sadness.

    Emotion dysregulation is a recognized symptom of adult Attention Deficit Hyperactivity Disorder (ADHD). The aim of this study is to induce sadness in adults suffering from ADHD and to investigate the impact of emotion regulation strategies on sadness intensity, and psychophysiological measures. Thirty-six adults diagnosed with ADHD were randomly assigned to either expressive suppression (SUPP) or acceptance (ACC) of emotion. Sadness was induced using a film clip. Participants estimated the intensity of sadness and the perception of being overwhelmed with emotion before (T1), immediately after (T2) and 2 min after the film (T3). Physiological measures were obtained. Sadness induction was effective in both conditions. The perception of being overwhelmed with emotion increased between T1 and T2 in both conditions, but persisted until T3 only in the expressive suppression condition whereas a decrease was observed in the acceptance condition. In ADHD expressive suppression of sadness seems to be associated to a prolonged recovery from the perception of being overwhelmed with emotion. Emotion-regulation via acceptance in contrast appears to allow faster recovery from the perception of being overwhelmed with emotion. To our knowledge, this is the first study to identify suppression as a critical mediator between an induced emotion and delayed recovery from emotional reactions in adult ADHD.

    We used the 2011 Arkansas Youth Risk Behavior Survey to estimate the prevalence of risky sexual behavior and sexual assault and to measure its association with teen suicidality. In Arkansas, 50.3% of students reported ever having sexual intercourse, 26% onset at 14 or younger, 36 % having had more than one partner, and 10.2% having been physically forced to have sex. "Being forced to have sex" was a risk factor for depression and all components of the suicide continuum. Additionally, early onset of sexual activity and having more than one partner increased the risk for depression, suicidal ideation, plan, and attempt. Suicide is a grievous and preventable tragedy, sadly standing among the leading causes of death for teens.' In this series, we examine risk factors for suicidality among Arkansas high school students; in this installment, we examine sexual behavior. A previous study utilizing the Rhode Island Youth Risk Behavior Survey (YRBS) found an association between having forced sexual intercourse and suicide. Furthermore, an association between psychiatric disorders and risky sexual behaviors, including both early onset and number of partners was found in a birth cohort study revealed. We hypothesize that Arkansas' teens reporting risky sexual behavior and sexual assault are at higher risk of depression and suicidality as well.

  8. Abstract recall of a happy memory to repair sad mood in dysphoria: A possible link to negative cognition.

    2015-01-01

    The capacity to repair sad mood through the deliberate recall of happy memories has been found to be impaired in dysphoric individuals. Rumination, or adopting an abstract processing mode, has been proposed as a possible mechanism underpinning this effect. In low and high dysphoric participants, we examined the relative consequences of adopting an abstract or concrete processing mode during happy memory recall or engaging in distraction for (1) mood repair and (2) cognitive content. Recalling a happy memory in either an abstract or concrete way resulted in greater happiness than distraction. Engaging in abstract recall of a happy memory resulted in high dysphoric participants generating negative evaluations and negative generalisations. These findings raise the interesting possibility that abstract processing of positive memories has the potential to generate negative cognition.

    Perceptions of defeat have been linked to a range of clinical disorders including psychosis. Perceived defeat sometimes increases in response to failure, but the strength of this association varies between individuals. The present research investigated whether trait reappraisal, a thought-focused coping style, amplified response to stressful events. Two studies (Study 1, n = 120 nonclinical participants; Study 2, n = 77 participants with schizophrenia-spectrum disorders) investigated whether trait reappraisal amplified feelings of defeat following an experience of failure versus success. Frequent reappraisers showed the largest increases in subjective defeat after failure versus success in both studies, with nonclinical participants with greater habitual reappraisal also showing larger increases in sadness and general negative affect. Frequent use of reappraisal may confer vulnerability to subjective defeat in response to stressful life events among nonclinical and clinical populations and could be an area for relapse prevention interventions to target.

    Full Text Available The conduct of employees in tourism, but also all the other factors that participate indirectly in the tourism industry of Novi Sad contributes greatly to creating the image of Novi Sad in the domestic and international market. In that sense, ethical conduct and respect of the code of ethics is the basis of acquiring a good image of Novi Sad and improving the tourist product of Novi Sad. Business ethics includes principles and rules of conduct based on general and business culture and the principles and rules that dominate in interpersonal communication. The complex of factors, which interact, influence ethical behavior of those who are directly and indirectly employed in tourism industry. Those are characteristics that each individual have, which he/she brings into the organization, and also the culture of the organization. The subject of this paper is to explore forms of unethical behavior in organizations that are directly or indirectly involved in the tourism industry, with which tourists and local population meet in Novi Sad. The aim of this work is to come to conclusions analyzing, which will help us to see the current situation and take measures that will improve the tourist product of Novi Sad. The study concluded that organizations that participate in the creation of tourist product of Novi Sad mostly do not have an ethical code of conduct, and those that have it, do not apply it to the necessary extent. In that sense it is necessary to motivate employees and to properly implement a code of ethics through ethical training, which is usually present in organizations only in normative, without the employees knowing the content of this code, as well as its importance for the organization and reflecting on the wider social level.

    Three experiments tested the hypothesis of implicit associations between happiness and the performance ease concept and between sadness and the performance difficulty concept. All three studies applied a sequential priming paradigm: participants categorized emotion words (Experiment 1) or facial expressions (Experiment 2) as positive or negative or as referring to ease or difficulty (Experiment 3). These targets were preceded by briefly flashed ease- or difficulty-related words or neutral non-words (Experiments 1 and 2) or by happy, sad, or neutral facial expressions (Experiment 3) as primes. As predicted, all three experiments revealed increases in reaction times in the sequential priming task from congruent trials (happiness/ease and sadness/difficulty) over neutral trials to incongruent trials (sadness/ease and happiness/difficulty). The findings provide evidence for implicit associative links of happiness with ease and sadness with difficulty, as posited by the implicit-affect-primes-effort model (Gendolla, Int J Psychophysiol 86:123-135, 2012; Soc Pers Psychol Compass 9:606-619, 2015).

    Combining five commonly observed symptoms of late-life depression to develop a short depression screening tool with similar sensitivity and specificity as the conventional, more time-consuming tools. We developed the St. Louis University AM SAD (Appetite, Mood, Sleep, Activity, and thoughts of Death) questionnaire. The frequency of each symptom in the prior 2 weeks is quantified as 0, 1, or 2. Patients 65 years or older from our clinics were administered the AM SAD, the Geriatric Depression Scale (GDS-15), the Montgomery-Asberg Depression Rating Scale (MADRS), and the St. Louis University Mental Status Exam (SLUMS). 100 patients were selected. AM SAD correlation with GDS was 0.72 and MADRS 0.80. AM SAD yielded a sensitivity and specificity of 79% and 62% against diagnosis of depression; of 88% and 62% with GDS-15; and 92% and 71% with MADRS. The AM SAD can be reliably used as a short depression screening tool in patients with a SLUMS score of 20 or higher. Copyright © 2015 American Association for Geriatric Psychiatry.

    Understanding the relative and joint prioritization of age- and valence-related face characteristics in adults' cortical face processing remains elusive because these two characteristics have not been manipulated in a single study of neural face processing. We used electroencephalography to investigate adults' P1, N170, P2 and LPP responses to infant and adult faces with happy and sad facial expressions. Viewing infant vs adult faces was associated with significantly larger P1, N170, P2 and LPP responses, with hemisphere and/or participant gender moderating this effect in select cases. Sad faces were associated with significantly larger N170 responses than happy faces. Sad infant faces were associated with significantly larger N170 responses in the right hemisphere than all other combinations of face age and face valence characteristics. We discuss the relative and joint neural prioritization of infant face characteristics and negative facial affect, and their biological value as distinct caregiving and social cues.

    Previous literature suggested that anger and sadness may be necessary to restore social bonds in the face of immediate relationship threat. The present research compared the social effectiveness of expressing anger and sadness in response to a negative personal evaluation. Results indicated that target anger in response to a negative competence evaluation, and target sadness in response to a negative warmth evaluation, had the most positive effects on the evaluators' subjectively perceived persuasiveness of the targets' communication (Study 1) and on the subjectively perceived fluency of the interaction by both interaction partners (Study 2). Results are discussed in light of the social functionality of emotion expression and the importance of interpersonal emotion congruency with evaluation content.

    It is known that the temporal cortex is involved in perception of emotional facial expressions, and the involvement is relatively independent of the emotional valence of those expressions. The present study revealed a valence-dependent aspect of the temporal cortex through individual differences analyses involving the neuroticism trait, one of the representative affective personality traits. Functional MRI was administered while subjects classified expressions of faces, and neuroticism scores were obtained from individual subjects. Significant brain activity was observed in the temporal pole (TP) during perception of both happy and sad expressions relative to neutral expressions. Correlational analyses revealed that TP activity during perception of sad expressions, but not happy expressions, correlated with the neuroticism scores. These results demonstrate differential roles for the temporal cortex in perception of happy and sad faces, and suggest that TP recruitment during understanding of negative emotions is dependent on the personality of the individuals.

    Group-based emotions play an important role in helping people feel that they belong to their group. People are motivated to belong, but does this mean that they actively try to experience group-based emotions to increase their sense of belonging? In this investigation, we propose that people may be motivated to experience even group-based emotions that are typically considered unpleasant to satisfy their need to belong. To test this hypothesis, we examined people's preferences for group-based sadness in the context of the Israeli National Memorial Day. In two correlational (Studies 1a and 1b) and two experimental (Studies 2 and 3) studies, we demonstrate that people with a stronger need to belong have a stronger preference to experience group-based sadness. This effect was mediated by the expectation that experiencing sadness would be socially beneficial (Studies 1 and 2). We discuss the implications of our findings for understanding motivated emotion regulation and intergroup relations.

    Full Text Available Background: Notwithstanding its value, there are challenges and limitations to implementing a dysphagia screening tool from a developed contexts in a developing context. The need for a reliable and valid screening tool for dysphagia that considers context, systemic rules and resources was identified to prevent further medical compromise, optimise dysphagia prognosis and ultimately hasten patients’ return to home or work.Methodology: To establish the validity and reliability of the South African dysphagia screening tool (SADS for acute stroke patients accessing government hospital services. The study was a quantitative, non-experimental, correlational cross-sectional design with a retrospective component. Convenient sampling was used to recruit 18 speech-language therapists and 63 acute stroke patients from three South African government hospitals. The SADS consists of 20 test items and was administered by speech-language therapists. Screening was followed by a diagnostic dysphagia assessment. The administrator of the tool was not involved in completing the diagnostic assessment, to eliminate bias and prevent contamination of results from screener to diagnostic assessment. Sensitivity, validity and efficacy of the screening tool were evaluated against the results of the diagnostic dysphagia assessment. Cohen’s kappa measures determined inter-rater agreement between the results of the SADS and the diagnostic assessment.Results and conclusion: The SADS was proven to be valid and reliable. Cohen’s kappa indicated a high inter-rater reliability and showed high sensitivity and adequate specificity in detecting dysphagia amongst acute stroke patients who were at risk for dysphagia. The SADS was characterised by concurrent, content and face validity. As a first step in establishing contextual appropriateness, the SADS is a valid and reliable screening tool that is sensitive in identifying stroke patients at risk for dysphagia within government

    Full Text Available BACKGROUND: Major depressive disorder (MDD is an important and highly prevalent mental disorder characterized by anhedonia and a lack of interest in everyday activities. Additionally, patients with MDD appear to have deficits in various cognitive abilities. Although a number of studies investigating the central auditory processing of low-level sound features in patients with MDD have demonstrated that this population exhibits impairments in automatic processing, the influence of emotional voice processing has yet to be addressed. To explore the automatic processing of emotional prosodies in patients with MDD, we analyzed the ability to detect automatic changes using event-related potentials (ERPs. METHOD: This study included 18 patients with MDD and 22 age- and sex-matched healthy controls. Subjects were instructed to watch a silent movie but to ignore the afferent acoustic emotional prosodies presented to both ears while continuous electroencephalographic activity was synchronously recorded. Prosodies included meaningless syllables, such as "dada" spoken with happy, angry, sad, or neutral tones. The mean amplitudes of the ERPs elicited by emotional stimuli and the peak latency of the emotional differential waveforms were analyzed. RESULTS: The sad MMN was absent in patients with MDD, whereas the happy and angry MMN components were similar across groups. The abnormal sad emotional MMN component was not significantly correlated with the HRSD-17 and HAMA scores, respectively. CONCLUSION: The data indicate that patients with MDD are impaired in their ability to automatically process sad prosody, whereas their ability to process happy and angry prosodies remains normal. The dysfunctional sad emotion-related MMN in patients with MDD were not correlated with depression symptoms. The blunted MMN of sad prosodies could be considered a trait of MDD.

    Full Text Available Although music could diversely influence consumer judgment process and behavior, it is still unclear whether music can evoke discrete emotions on consumers and influence consumer evaluation toward certain advertisements. This research proposes that music could evoke sad and anxious emotion on consumers; subsequently, consumers would regulate their negative emotions in accordance to their emotion orientations: Consumers who feel sad would show high evaluation toward happy-themed advertisement, while consumers who feel anxious would show high evaluation toward calm-themed advertisement. This paper concludes with the discussion of theoretical and practical implications and conclusion of this study.

    2016-01-01

    Children using cochlear implants (CIs) develop speech perception but have difficulty perceiving complex acoustic signals. Mode and tempo are the two components used to recognize emotion in music. Based on CI limitations, we hypothesized children using CIs would have impaired perception of mode cues relative to their normal hearing peers and would rely more heavily on tempo cues to distinguish happy from sad music. Study participants were children with 13 right CIs and 3 left CIs (M = 12.7, SD = 2.6 years) and 16 normal hearing peers. Participants judged 96 brief piano excerpts from the classical genre as happy or sad in a forced-choice task. Music was randomly presented with alterations of transposed mode, tempo, or both. When music was presented in original form, children using CIs discriminated between happy and sad music with accuracy well above chance levels (87.5%) but significantly below those with normal hearing (98%). The CI group primarily used tempo cues, whereas normal hearing children relied more on mode cues. Transposing both mode and tempo cues in the same musical excerpt obliterated cues to emotion for both groups. Children using CIs showed significantly slower response times across all conditions. Children using CIs use tempo cues to discriminate happy versus sad music reflecting a very different hearing strategy than their normal hearing peers. Slower reaction times by children using CIs indicate that they found the task more difficult and support the possibility that they require different strategies to process emotion in music than normal.

    2008-06-01

    Misery is not miserly: Sadness increases the amount of money that decision makers give up to acquire a commodity. The present research investigated when and why the misery-is-not-miserly effect occurs. Drawing on William James's concept of the material self, we tested a model specifying relationships among sadness, self-focus, and the amount of money that decision makers spend. Consistent with our Jamesian hypothesis, results demonstrated that the misery-is-not-miserly effect occurs only when self-focus is high. That is, self-focus moderates the effect of sadness on spending. Moreover, mediational analyses revealed that, at sufficiently high levels, self-focus mediates (explains) the relationship between sadness and spending. Because the study used real commodities and real money, the results hold implications for everyday decisions, as well as implications for the development of theory. For example, economic theories of spending may benefit from incorporating psychological theories -- specifically, theories of emotion and the self -- into their models.

    2010-01-01

    Full Text Available Cognitive reactivity to sad mood refers to the degree to which a mild dysphoric state reactivates negative thinking patterns. In this research, the contribution of the history of depression, the length of the current depressive episode and the intensity of the depressive symptoms were assessed in explaining the cognitive reactivity to sad mood measured with the Leiden Index of Depression Sensitivity (LEIDS. The sample consisted of 123 depressed outpatients. The results of principal components analysis suggested a three-factor solution of the LEIDS. The intensity of depressive symptoms, the history of depression and the length of the current depressive episode were all significant in explaining cognitive reactivity to sad mood. We have also found out a significant effect of interaction of the history of depression and the length of the current depressive episode, which demonstrated that a prolonged depression does not induce a stronger cognitive reactivity to sad mood during the relapse of a depressive episode, while during the first depressive episode a longer duration of depression does induce a stronger cognitive reactivity. Such a result demonstrates that the length of the first depressive episode, regardless of its intensity, is crucially important for the formation of cognitive reactivity.

    Musical emotions, such as happiness and sadness, have been investigated using instrumental music devoid of linguistic content. However, pop and rock, the most common musical genres, utilize lyrics for conveying emotions. Using participants' self-selected musical excerpts, we studied their behavior and brain responses to elucidate how lyrics interact with musical emotion processing, as reflected by emotion recognition and activation of limbic areas involved in affective experience. We extracted samples from subjects' selections of sad and happy pieces and sorted them according to the presence of lyrics. Acoustic feature analysis showed that music with lyrics differed from music without lyrics in spectral centroid, a feature related to perceptual brightness, whereas sad music with lyrics did not diverge from happy music without lyrics, indicating the role of other factors in emotion classification. Behavioral ratings revealed that happy music without lyrics induced stronger positive emotions than happy music with lyrics. We also acquired functional magnetic resonance imaging data while subjects performed affective tasks regarding the music. First, using ecological and acoustically variable stimuli, we broadened previous findings about the brain processing of musical emotions and of songs versus instrumental music. Additionally, contrasts between sad music with versus without lyrics recruited the parahippocampal gyrus, the amygdala, the claustrum, the putamen, the precentral gyrus, the medial and inferior frontal gyri (including Broca's area), and the auditory cortex, while the reverse contrast produced no activations. Happy music without lyrics activated structures of the limbic system and the right pars opercularis of the inferior frontal gyrus, whereas auditory regions alone responded to happy music with lyrics. These findings point to the role of acoustic cues for the experience of happiness in music and to the importance of lyrics for sad musical emotions.

    In clarifying the clinical definition of an episode of major depression, DSM-5 equates bereavement with a number of other loss-related stressors (e.g. financial ruin, serious medical problems) and infers differences between such loss-related and non-loss-related responses. We undertook a study with the aim of examining the likelihood of varying life stressors leading to depression or to other emotional responses, and so allowing consideration as to whether bereavement might be equivalent to other loss-related stressful triggers. We studied a sample comprising sub-sets of those likely to have either experienced or never experienced a clinical depressive episode and report data for both the whole sample and the separate sub-sets. Participants were asked to report their exposure to 16 differing stressors and, given definitions of depression, grief, sadness and stress, to rate (in order of importance) their primary and secondary reactions if so experienced. Only one event (i.e. the individual being left by their partner) generated depression as the most likely response within the sample. A grief reaction was nominated as the most likely primary response to the death of a first-degree relative (52%) and was also a relatively common primary response to the death of a more distant relative or close family friend (36%). While one-fourth (24%) nominated grief as the primary response to being left by one's partner, it was rarely nominated as a primary response to all other events, including the DSM-5 'loss-related' exemplars of a financial crisis and of a medical illness (rates of 3% and 2%, respectively). As participants were given a definition of the emotional responses and candidate contexts, their responses may have been a reflection of the definitions provided. Additionally, a retrospective, self-report design was used which may have impacted on the veracity of responses. Findings position a grief response as showing relative specificity to bereavement events and that

    Greater levels of conscientiousness have been associated with lower levels of negative affect. We focus on one mechanism through which conscientiousness may decrease negative affect: effective emotion regulation, as reflected by greater recovery from negative stimuli. In 273 adults who were 35-85 years old, we collected self-report measures of personality including conscientiousness and its self-control facet, followed on average 2 years later by psychophysiological measures of emotional reactivity and recovery. Among middle-aged adults (35-65 years old), the measures of conscientiousness and self-control predicted greater recovery from, but not reactivity to, negative emotional stimuli. The effect of conscientiousness and self-control on recovery was not driven by other personality variables or by greater task adherence on the part of high conscientiousness individuals. In addition, the effect was specific to negative emotional stimuli and did not hold for neutral or positive emotional stimuli.

    This study adopted empathy induced by sadness which is a kind of true human emotions as research object,using true and observable earthquake situation pictures with strong social reality meaning as stimuli materials. Based on the neuroscience perspective, previous research on empathy was mainly limited to sensation (especially pain), and the present study broke those limitations. With the event-related potential technologies and the picture perception paradigms, we explored whether the extent of situation reality could modulate empathy for sadness. Fourteen right handed undergraduate and postgraduate students (7 males and 7 females) were recruited to take part in the study. Participants were presented with earthquake pictures (sad stimulus) or life pictures (neutral stimulus) that were in real or film situation which was formed through instructions. Participants were instructed to view naturally. The behavioral results showed that subjective empathic response which induced by the real earthquake situation pictures was more intense than that induced by the film earthquake situation pictures. The ERP results showed early differentiation between earthquake and life pictures over the frontal-central area at 180 ms after sensory stimulation and a long-latency empathic response was observed after 300 ms over the central–parietal regions. The late empathic response was modulated by situation reality. Moreover, the mean ERP amplitudes induced by the film and real earthquake situation pictures at 160~180 ms and 300~350 ms were respectively correlated with the subjective reports of the degree of perceived sadness of self. These results suggest that empathy research can be pushed to empathy for sadness with real emotional characteristics. Earthquake situation pictures can be used as experiment materials that induced empathy for sadness. The different degrees of situational realities formed by the cognitive evaluation which is based on induction can modulate the empathy for

    Full Text Available Abstract Background Mood disorders are a major public health problem in the United States as well as globally. Less information exists however, about the health burden resulting from subsyndromal levels of depressive symptomatology, such as feeling sad, blue or depressed, among the general U.S. population. Methods As part of an optional Quality of Life survey module added to the U.S. Behavioral Risk Factor Surveillance System, between 1995–2000 a total of 166,564 BRFSS respondents answered the question, "During the past 30 days, for about how many days have you felt sad, blue, or depressed?" Means and 95% confidence intervals for sad, blue, depressed days (SBDD and other health-related quality of life (HRQOL measures were calculated using SUDAAN to account for the BRFSS's complex sample survey design. Results Respondents reported a mean of 3.0 (95% CI = 2.9–3.1 SBDD in the previous 30 days. Women (M = 3.5, 95% CI = 3.4–3.6 reported a higher number of SBDD than did men (M = 2.4, 95% CI = 2.2–2.5. Young adults aged 18–24 years reported the highest number of SBDD, whereas older adults aged 60–84 reported the fewest number. The gap in mean SBDD between men and women decreased with increasing age. SBDD was associated with an increased prevalence of behaviors risky to health, extremes of body mass index, less access to health care, and worse self-rated health status. Mean SBDD increased with progressively higher levels of physically unhealthy days, mentally unhealthy days, unhealthy days, activity limitation days, anxiety days, pain days, and sleepless days. Conclusion Use of this measure of sad, blue or depressed days along with other valid mental health measures and community indicators can help to assess the burden of mental distress among the U.S. population, identify subgroups with unmet mental health needs, inform the development of targeted interventions, and monitor changes in population levels of mental distress over time.

    Here, we used functional magnetic resonance imaging to test for the lateralization of the brain regions specifically involved in the recognition of negatively and positively valenced musical emotions. The manipulation of two major musical features (mode and tempo), resulting in the variation of emotional perception along the happiness-sadness axis, was shown to principally involve subcortical and neocortical brain structures, which are known to intervene in emotion processing in other modalities. In particular, the minor mode (sad excerpts) involved the left orbito and mid-dorsolateral frontal cortex, which does not confirm the valence lateralization model. We also show that the recognition of emotions elicited by variations of the two perceptual determinants rely on both common (BA 9) and distinct neural mechanisms.

    Full Text Available During the 1999 NATO bombing of Yugoslavia, the second largest Yugoslav city Novi Sad was one of the cities that bore the brunt of the bombing. According to NATO press releases, the bombing targeted oil refineries, roads, bridges, and telecommunications relay stations, facilities which had used for military purposes. The bombing of Novi Sad's refinery caused fires which burned 50000 tons of crude oil, sending toxins and carcinogens into the air and contaminating groundwater. The bombing of the city caused great damage to local civilians, including severe pollution and widespread ecological damage, health consequences which will remain for years as well as permanent psychological consequences caused by almost 3 months of trauma and fear.

    Autobiographic memory undergoes progressive deterioration during the evolution of Alzheimer's disease (AD). The aim of this study was to analyze mechanisms which facilitate recovery of autobiographic memories. We used a repeatedly employed mechanism, music, with the addition of an emotional factor. Autobiographic memory provoked by a variety of sounds (music which was happy, sad, lacking emotion, ambient noise in a coffee bar and no sound) was analyzed in a sample of 25 patients with AD. Emotional music, especially sad music for remote memories, was found to be the most effective kind for recall of autobiographic experiences. The factor evoking the memory is not the music itself, but rather the emotion associated with it, and is useful for semantic rather than episodic memory.

    Responses to fear- and sadness-inducing films were assessed using a broad range of cardiovascular (heart rate, T-wave amplitude, low- and high-frequency heart rate variability, stroke volume, preejection period, left-ventricular ejection time, Heather index, blood pressure, pulse amplitude and transit time, and finger temperature), electrodermal (level, response rate, and response amplitude), and respiratory (rate, tidal volume and its variability, inspiratory flow rate, duty cycle, and end-tidal pCO(2)) measures. Subjective emotional experience and facial behavior (Corrugator Supercilii and Zygomaticus Major EMG) served as control measures. Results indicated robust differential physiological response patterns for fear, sadness, and neutral (mean classification accuracy 85%). Findings are discussed in terms of the fight-flight and conservation-withdrawal responses and possible limitations of a valence-arousal categorization of emotion in affective space.

    Full Text Available Background: Symptoms of depression are often reported among patients with a cancer diagnosis. Strong sense of coherence (SOC is shown to be associated with less depression in the general older population and among nursing homes (NH residents in particular. Knowledge about mixed-methods perspectives that examine symptoms of depression and SOC among cognitively intact NH residents with cancer is scarce. Aim: To investigate symptoms of depression and SOC among NH residents who are cognitively intact and have cancer. Methods: We used a quantitatively driven mixed-methods design with sequential supplementary qualitative components. We facilitated the collection of quantitative survey data of 60 NH residents (≥ 65 years with cancer using the Geriatric Depression Scale (GDS and SOC scale. The supplementary psychosocial component comprised qualitative research interviews about experiences related to depression with nine respondents from the same cohort. Results: In fully adjusted multiple regression analysis of the sociodemographic variables, the GDS was significantly correlated with SOC (P < 0.001. The experience of sadness was identified by the following theme: sadness. Coping with the experience of symptoms of depression was dominated by coping with sadness. Conclusion: More than half the NH residents reported symptoms of depression, and the SOC was associated with reduced symptoms. A mixed-methods design contributed to nuanced and detailed information about the meaning of depression, and the supplementary component informs and supports the core component. To improve the situation of NH residents with cancer, more attention should be paid to the residents’ experience of symptoms of depression and their SOC.

    Full Text Available Phased software engineering process continues to be the most popular paradigm leading to devise and drawing-up all system architectural designs. In this paper we trying to explore and examine the most significant software engineering activity: Software architectural design. In this paper we discuss and evaluate an integrated service-based (the common and modern architectural styles upon which many systems are currently based software architectural design framework called SbSAD. SbSAD is, mainly, built on top a proprietary micro-phased design process. In this paper, we first reconsider and refine such process in order to become more flexible. We, then, trying to evaluate this process by providing one devoted CASE-like prototype built using java technologies. Our approach consists of building overall software architectures while being based on the concept of business front-end services. The experiments show that: applying such strategy may cause some confliction with the so known SOA and may disorient both readers and designers. However, at the end, we testify that our service-based process should not have any direct connection with the SOA style. Working on some re-drawing and mapping rules leading to transcript SbSAD into SOA could characterize our future works.

    This study examined adults' affective and facial reactions to tastes which differ in quality and valence, and the impact of sadness and joy on these reactions. Thirty-six male and female subjects participated voluntarily. Subjects each tasted 6 ml of a sweet chocolate drink, a bitter quinine solution (0.0015 M) and a bitter-sweet soft drink. Following a baseline period, either joy or sadness was induced using film clips before the same taste stimuli were presented for a second time. Subjects rated the drinks' pleasantness and intensity of taste immediately after each stimulus presentation. Facial reactions were videotaped and analysed using the Facial Action Coding System (FACS [P. Ekman, W.V. Friesen, Facial Action Coding System: Manual. Palo Alto, CA: Consulting Psychologists Press; 1978., P. Ekman, W. Friesen, J. Hager, Facial Action Coding System. Salt Lake City, Utah: Research Nexus; 2002.]). The results strongly indicated that the tastes produced specific facial reactions that bear strong similarities to the facial reactivity patterns found in human newborns. The data also suggest that some adults' facial reactions serve additional communicative functions. Emotions modulated taste ratings, but not facial reactions to tastes. In particular, ratings of the sweet stimulus were modulated in congruence with emotion quality, such that joy increased and sadness decreased the pleasantness and sweetness of the sweet stimulus. No emotion-congruent modulation was found for the pleasantness and intensity ratings of the bitter or the bitter-sweet stimulus. This 'robustness' of bitter taste ratings may reflect a biologically meaningful mechanism.

    Kim, Sunny Jung; Niederdeppe, Jeff

    2014-01-01

    The authors conducted an experiment among U.S. college students (N = 115) to assess the effects of anger- and sadness-framed television antismoking advertisements on viewers' emotional response, impressions of the speaker, source likability, and empathy toward the speaker. The study was based on the fundamental assumptions of discrete emotions and was operationalized using the principles of universal facial expressions. The authors also constructed a path model to investigate how these variables predicted one's attitude toward smoking, attitude toward the tobacco industry, and intentions to smoke. Supporting study hypotheses, the anger-framed message increased the perceived dominance of the speaker relative to the other conditions. Perceived dominance, in turn, was negatively associated with smoking attitudes and, indirectly, smoking intentions. Contrary to study hypotheses, the sadness-framed message did not increase sad emotional responses, source likability, or empathy relative to the no emotion-framed message. The anger-framed message unexpectedly appeared to decrease these outcomes. Empathy and source likability were associated with positive attitudes toward the tobacco industry, but these attitudes did not predict intentions to smoke. The authors discuss the implications of these findings.

  1. Memorable Experiences with Sad Music-Reasons, Reactions and Mechanisms of Three Types of Experiences.

    Tuomas Eerola

    Full Text Available Reactions to memorable experiences of sad music were studied by means of a survey administered to a convenience (N = 1577, representative (N = 445, and quota sample (N = 414. The survey explored the reasons, mechanisms, and emotions of such experiences. Memorable experiences linked with sad music typically occurred in relation to extremely familiar music, caused intense and pleasurable experiences, which were accompanied by physiological reactions and positive mood changes in about a third of the participants. A consistent structure of reasons and emotions for these experiences was identified through exploratory and confirmatory factor analyses across the samples. Three types of sadness experiences were established, one that was genuinely negative (Grief-Stricken Sorrow and two that were positive (Comforting Sorrow and Sweet Sorrow. Each type of emotion exhibited certain individual differences and had distinct profiles in terms of the underlying reasons, mechanisms, and elicited reactions. The prevalence of these broad types of emotional experiences suggested that positive experiences are the most frequent, but negative experiences were not uncommon in any of the samples. The findings have implications for measuring emotions induced by music and fiction in general, and call attention to the non-pleasurable aspects of these experiences.

    Reactions to memorable experiences of sad music were studied by means of a survey administered to a convenience (N = 1577), representative (N = 445), and quota sample (N = 414). The survey explored the reasons, mechanisms, and emotions of such experiences. Memorable experiences linked with sad music typically occurred in relation to extremely familiar music, caused intense and pleasurable experiences, which were accompanied by physiological reactions and positive mood changes in about a third of the participants. A consistent structure of reasons and emotions for these experiences was identified through exploratory and confirmatory factor analyses across the samples. Three types of sadness experiences were established, one that was genuinely negative (Grief-Stricken Sorrow) and two that were positive (Comforting Sorrow and Sweet Sorrow). Each type of emotion exhibited certain individual differences and had distinct profiles in terms of the underlying reasons, mechanisms, and elicited reactions. The prevalence of these broad types of emotional experiences suggested that positive experiences are the most frequent, but negative experiences were not uncommon in any of the samples. The findings have implications for measuring emotions induced by music and fiction in general, and call attention to the non-pleasurable aspects of these experiences.

    Full Text Available Short-term synaptic depression (STD is a common form of activity-dependent plasticity observed widely in the nervous system. Few molecular pathways that control STD have been described, but the active zone (AZ release apparatus provides a possible link between neuronal activity and plasticity. Here, we show that an AZ cytomatrix protein CAST and an AZ-associated protein kinase SAD-B coordinately regulate STD by controlling reloading of the AZ with release-ready synaptic vesicles. SAD-B phosphorylates the N-terminal serine (S45 of CAST, and S45 phosphorylation increases with higher firing rate. A phosphomimetic CAST (S45D mimics CAST deletion, which enhances STD by delaying reloading of the readily releasable pool (RRP, resulting in a pool size decrease. A phosphonegative CAST (S45A inhibits STD and accelerates RRP reloading. Our results suggest that the CAST/SAD-B reaction serves as a brake on synaptic transmission by temporal calibration of activity and synaptic depression via RRP size regulation.

    Full Text Available It is well established that mood influences many cognitive processes, such as learning and executive functions. Although statistical learning is assumed to be part of our daily life, as mood does, the influence of mood on statistical learning has never been investigated before. In the present study, a sad vs. neutral mood was induced to the participants through the listening of stories while they were exposed to a stream of visual shapes made up of the repeated presentation of four triplets, namely sequences of three shapes presented in a fixed order. Given that the inter-stimulus interval was held constant within and between triplets, the only cues available for triplet segmentation were the transitional probabilities between shapes. Direct and indirect measures of learning taken either immediately or 20 minutes after the exposure/mood induction phase revealed that participants learned the statistical regularities between shapes. Interestingly, although participants from the sad and neutral groups performed similarly in these tasks, subjective measures (confidence judgments taken after each trial revealed that participants who experienced the sad mood induction showed increased conscious access to their statistical knowledge. These effects were not modulated by the time delay between the exposure/mood induction and the test phases. These results are discussed within the scope of the robustness principle and the influence of negative affects on processing style.

    This paper describes two small aperture array demonstrators called Medicina and Sardinia Array Demonstrators (MAD and SAD, respectively). The objectives of these instruments are to acquire experience and test new technologies for a possible application to the low-frequency aperture array of the low-frequency telescope of the Square Kilometer Array phase 1 (SKA1-LOW). The MAD experience was concluded in 2014, and it turned out to be an important test bench for implementing calibration techniques based on an artificial source mounted in an aerial vehicle. SAD is based on 128 dual-polarized Vivaldi antennas and is 1 order of magnitude larger than MAD. The architecture and the station size of SAD, which is along the construction phase, are more similar to those under evaluation for SKA1-LOW, and therefore, SAD is expected to provide useful hints for SKA1-LOW.

    Emerging evidence suggests that emotion and affect modulate the relation between sleep and cognition. In the present study, we investigated the role of rapid-eye movement (REM) sleep in mood regulation and memory consolidation for sad stories. In a counterbalanced design, participants (n = 24) listened to either a neutral or a sad story during two sessions, spaced one week apart. After listening to the story, half of the participants had a short (45 min) morning nap. The other half had a long...

    The schedule for affective disorders and schizophrenia for school-age children (K-SADS) is one of the most commonly used standardized diagnostic interviews in child and adolescent psychiatry. Validity studies are scarce, and limited to concurrent validity with other measures and clinical diagnoses. To evaluate the K-SADS interview in an outpatient child and adolescent psychiatry (CAP) setting with a Longitudinal Expert All Data (LEAD) procedure. CAP residents performed a K-SADS-PL interview with the revised 2009 version containing the new PDD section on 239 clinically referred outpatients of 6-17 years old and their parent(s). A consensus LEAD diagnosis by two senior clinicians 1.2 (SD = 0.6) years later was based on clinical records including the K-SADS and subsequent information from further assessments, information from teachers and other informants, outcome of treatment, and at least three visits after the K-SADS. Predictive validity for K-SADS vs LEAD diagnoses were good-to-excellent for broader categories of anxiety disorders (κ = 0.94), depressive (κ = 0.91), behavioural (κ = 0.91) and tic (κ = 0.81) disorders, good for ADHD (κ = 0.80), and good-to-moderate for autism spectrum disorders (κ = 0.62). Bipolar, psychotic, and eating disorders were too few to be analysed. The K-SADS diagnoses elicited from an interview with the child and one from parents on one occasion have an excellent validity for most major child psychiatric disorders. ADHD can be reliably diagnosed at one visit, but clinicians need to stay alert for possible undiagnosed ADHD. Diagnosing autism with K-SADS-PL 2009 version at one visit is not advisable.

Story recall, mood evolution and changes in emotional response to the re-exposure to the story were assessed after the nap. Although recall performance was similar for sad and neutral stories irrespective of nap duration, sleep measures were correlated with recall performance in the sad story condition only. After the long nap, REM sleep density positively correlated with retrieval performance, while re-exposure to the sad story led to diminished mood and increased skin conductance levels. Our results suggest that REM sleep may not only be associated with the consolidation of intrinsically sad material, but also enhances mood reactivity, at least on the short term.

    Autoerotic fatalities in the Greater Dusseldorf area correspond to the relevant medicolegal literature. Our results included exclusively young to middle-aged, usually single men who were found dead in their city apartments. Clothing and devices used showed a great variety. Women's or fetish clothing and complex shackling or hanging devices were disproportionately frequent. In most cases, death occurred due to hanging or ligature strangulation. There was no increased incidence of underlying psychiatric disorders. In most of the deceased no or at least no remarkable alcohol intoxication was found. Occasionally, it may be difficult to reliably differentiate autoerotic accidents, accidents occurring in connection with practices of bondage & discipline, dominance & submission (BDSM) from natural death, suicide or homicide.

    Major depressive disorder (MDD) occurs with a high prevalence among mental illnesses. MDD patients experience sadness and hopelessness, with blunted affective reactivity. However, such depressive episodes are also key symptoms in other depressive disorders, like Bipolar Disorder (BPD) or Seasonal Affective Disorder (SAD). Moreover, depressive symptoms can also be found in healthy individuals, but are experienced as less severe or for a shorter duration than in patients. Here, it is aimed to summarize studies investigating odor perception in depression, including depressive states in healthy individuals and patient populations. Odor perception in depression has been assessed with psychophysical methods (olfactory sensitivity, odor identification, and discrimination), and odor ratings (intensity, emotional valence, familiarity). In addition, some studies investigated affective reactions to odors, and physiological and anatomical correlates of odor perception in depression. The summary reveals that MDD is associated with reduced olfactory sensitivity. However, odor identification and discrimination scores seem to be unaffected by depression. The reduced olfactory sensitivity might be associated with a reduced ability to encode olfactory information and a reduced volume of the olfactory bulb. While similar processes seem to occur in healthy individuals experiencing depressive states, they have not been observed in BPD or SAD patients. However, in order to conclude that the reduced olfactory sensitivity is directly linked to depression, it is suggested that studies should implement control measures of cognitive performances or perceptual abilities in other stimulus modalities. It is concluded that the reduced olfactory performance in MDD patients seems to be disorder-, modality-, and test-specific, and that the application of an appropriate olfactory and cognitive test-battery might be highly useful in the differential diagnosis of MDD.

    Full Text Available Background/Aim. Data on sodium intake and sources of sodium in the diet in Serbia are limited. The aim of this study was to estimate the sodium intake and identify the sources of sodium in the diet of undergraduate students attending the University of Novi Sad. Methods. Students completed a questionnaire to gather data on their gender, age and university faculty attended, and then a 24 h dietary recall. The sodium intake of the students was calculated using the dietary recall data and data on the sodium content of foods. The contribution of different food groups as well as of specific foodstuffs to the total sodium intake was calculated. Results. The mean estimated sodium intake of the students was 3,938.5 ± 1,708.1 mg/day. The sodium intake of 89.1% of the surveyed students exceeded the guideline for sodium intake, the majority of the sodium coming from processed foods (78.9% of the total sodium intake. The food groups that contributed the most to the total sodium intake of the students were meat and meat products (21.7% and cereals and cereal-based products (18.6%. Bread and other bakery products were responsible for 13.1% of the total sodium intake. Conclusion. High sodium intake in students of the University of Novi Sad puts them at high risk of developing high blood pressure. The food industry should work towards reformulating products with high sodium content, especially bread and other bakery products. Efforts should be taken to reduce sodium intake among undergraduate students in Novi Sad.

    Full Text Available En el presente texto se articulan desarrollos realizados por Freud y Lacan a propósito del duelo con el fin de responder a la relación entre éste y lo que Lacan propone en Televisión sobre la tristeza y el rechazo del inconsciente. Para tales fines, se parte de las preguntas e intentos de respuestas dadas por Freud en el plano de la economía libidinal a propósito del duelo, para pasar a los desarrollos de orden ético y moral que Lacan plantea a propósito de la tristeza. De esta forma, el rechazo del inconsciente presente en las psicosis se distingue del que tiene lugar en el duelo, al considerar la tristeza un afecto que dará cuenta del rechazo del deseo del Otro. // This text articulates developments made by Freud and Lacan about mourning to attempt a response on how this relates to Lacan‟s proposal in Television about sadness and rejection of the unconscious. To do this, the text departs from the questions and answers given by Freud in the field of the economy of the libido referring to mourning and then moves on to the ethical and moral aspects that Lacan refers about sadness. Consequently, from this perspective the rejection of the unconscious in the psychosis is different from the one that takes place in mourning, considering sadness as an affection that will evidence the rejection of the desire of the Other.

The obtained results confirmed the presence of BPA above the limit of quantification (6 ng/L in 22 out of 32 water samples at all eight sampling sites. Тhe BPA concentration varied from 1 for autumn, spring and summer. The high potential risk which is attributed to the elevated summer concentrations is probably the result of the increased human activates and weather conditions.

    Laboratory and field spectral reflectance measurements of healthy and infected St. Augustine grass were made using several different instruments. Spectral differences between healthy and infected grass occured in the visible and near infrared regions. Multiband and color infrared photographs were taken of healthy and diseased turf from ground-based platforms and low altitude aircraft. Qualitative (density slicing) and quantitative (transmission densitometry) analyses revealed distinct tonal differences between healthy and St. Augustine disease (SAD) infected grass. Similar experiments are described for determining if healthy and diseased grass can be distinguished from waterstressed grass and grass deficient in either nitrogen or iron.

    The sulfur SAD phasing method was successfully used to determine the structure of the N-terminal domain of HCV E1 from low-resolution diffracting crystals by combining data from 32 crystals. Single-wavelength anomalous dispersion of S atoms (S-SAD) is an elegant phasing method to determine crystal structures that does not require heavy-atom incorporation or selenomethionine derivatization. Nevertheless, this technique has been limited by the paucity of the signal at the usual X-ray wavelengths, requiring very accurate measurement of the anomalous differences. Here, the data collection and structure solution of the N-terminal domain of the ectodomain of HCV E1 from crystals that diffracted very weakly is reported. By combining the data from 32 crystals, it was possible to solve the sulfur substructure and calculate initial maps at 7 Å resolution, and after density modication and phase extension using a higher resolution native data set to 3.5 Å resolution model building was achievable.

  18. Women's greater ability to perceive happy facial emotion automatically: gender differences in affective priming.

    Full Text Available There is evidence that women are better in recognizing their own and others' emotions. The female advantage in emotion recognition becomes even more apparent under conditions of rapid stimulus presentation. Affective priming paradigms have been developed to examine empirically whether facial emotion stimuli presented outside of conscious awareness color our impressions. It was observed that masked emotional facial expression has an affect congruent influence on subsequent judgments of neutral stimuli. The aim of the present study was to examine the effect of gender on affective priming based on negative and positive facial expression. In our priming experiment sad, happy, neutral, or no facial expression was briefly presented (for 33 ms and masked by neutral faces which had to be evaluated. 81 young healthy volunteers (53 women participated in the study. Subjects had no subjective awareness of emotional primes. Women did not differ from men with regard to age, education, intelligence, trait anxiety, or depressivity. In the whole sample, happy but not sad facial expression elicited valence congruent affective priming. Between-group analyses revealed that women manifested greater affective priming due to happy faces than men. Women seem to have a greater ability to perceive and respond to positive facial emotion at an automatic processing level compared to men. High perceptual sensitivity to minimal social-affective signals may contribute to women's advantage in understanding other persons' emotional states.

    Lower limb traction apophysitis is common in young athletes, occurring at sites such as the tibial tubercle (Osgood-Schlatter disease) and distal patella (Sinding-Larsen-Johansson disease). Around the hip, iliac apophysitis is well recognized, but no cases of greater trochanter apophysitis have previously been reported. We describe the case of a 15-year-old male basketball player with a 2-month history of the right hip pain and significant functional limitation. X-rays revealed widening of the greater trochanter apophysis with subchondral sclerosis, consistent with a diagnosis of traction apophysitis. The patient was treated with a period of relative rest and anti-inflammatory medication. He gradually returned to full athletic activity, including basketball, without recurrence of pain or limitation. We describe the first reported case of traction apophysitis of the greater trochanter. The unique muscular anatomy of this apophysis with balanced forces explains the rarity of this condition. If encountered, rest and activity modification is the recommended treatment.

    Full Text Available Tuberculosis has been reported in almost all bones of body. The great trochanter tuberculosis (GTT installation is insidious and clinical symptoms are often vague with moderate painful swelling and stiffness. GTT is about 0,2 to 2% of all osteo-articular tuberculosis, occurring most commonly by hematogenous seeding secondary to primary focus elsewhere, more commonly in the lungs. Isolated GTT is unusual and thus its awareness is slow and diagnosis is often delayed.

    Diagnostic interviews are valuable tools for generating reliable and valid psychiatric diagnoses. However, little is known about the diagnostic effects of implementing such an interview into the standard diagnostic procedure of a child psychiatric clinic. Therefore, we reviewed discharge diagnoses of psychiatric patients (age: 8-12 years; combined sample of inpatients and day hospital patients) over two intervals before and after implementing the semi-structured diagnostic interview K-SADS-PL as a diagnostic tool during intake. Each interval was a two year period spanning from 2009-2010 (pre sample; n=177) and from 2012-2013 (post sample; n=132). The number of diagnoses per patient and the co-morbidity rate increased significantly in the post sample. Furthermore, the percentage of children with a nonspecific diagnosis "other mixed disorders of conduct and emotions" (ICD-10: F92.8) decreased significantly after using the K-SADS-PL. Regarding the main diagnostic categories, a significant increase in the number of anxiety disorders and stress-related and somatoform disorders was found in the post sample. The results suggest that implementing a semi-structured interview into the daily routine of child psychiatry may have a substantial impact on discharge diagnoses. Practical implications are discussed and ideas for future research are given.

    Jaimee Faith J. Santos

    2014-06-01

    Full Text Available As a first place winner of the Centennial Literary Prize, Eric Gamalinda’s My Sad Republic (2000 is inextricably tied to discourses about the nation and its formation. In particular, it demonstrates the mutually constitutive relationship between the nation and the novel. My Sad Republic’s participation in the political project of nation-building is revealed not only in its entry and subsequent success in a large-scale government-sponsored contest, but also in its documentation of the components of nation-formation. Furthermore, the novel mimics the heterogeneous composition of the nation through its combination of historical, marvelous and romantic elements, as well as through the multiplicity of voices that its characters represent. Paradoxically, however, the novel also shows how the very diversity of individuals that constitute the nation inevitably leads to violent conflicts that hinder the actualization of the nation. The novel hence encourages the idea of self-sacrifice, the surrender of various personal agenda for the sake of a single national interest. At the same time, it also shows how the inherently problematic construction of the nation can be imagined only through literature, specifically the novel. The nation, in other words, depends on the novel not only for the promotion of nationalist ideals, but also for its very existence.

    Full Text Available The research presented in this paper analyses the socio-economic conditions that preceded the construction of the Sokolski dom in Novi Sad. The construction of this building of great cultural and historical value, during the process of transformation and enlargement of the main square throughout the interwar period, has made a significant impact on the further development of the central areas of the city. The realization of the building was part of the opening of the city towards the Danube, and thus it sets an architectural framework for future spatial development. In addition, architectural and stylistic features of this cultural monument are presented, occupying an important place in the oeuvre of architect Đorđe Tabaković, one of the most important creators of the modern period. Afterwards the research points to the significant stages through which this institution has passed in its history, with emphasis on the different social, cultural and political influences and consequences which have followed. Finally, it has been concluded that Sokolsko društvo, from its establishment until the present day, as a commissioner and a regular user of the facility, has great social significance and impact on the cultural, educational and sports development of the population of Novi Sad.

    The severity of motor and non-motor symptoms of progressive supranuclear palsy (PSP) has a profound impact on social interactions of affected individuals and may, consequently, contribute to alter emotion recognition. Here we investigated facial emotion recognition impairment in PSP with respect to Parkinson's disease (PD), with the primary aim of outlining the differences between the two disorders. Moreover, we applied an intensity-dependent paradigm to examine the different threshold of encoding emotional faces in PSP and PD. The Penn emotion recognition test (PERT) was used to assess facial emotion recognition ability in PSP and PD patients. The 2 groups were matched for age, disease duration, global cognition, depression, anxiety, and daily L-Dopa intake. PSP patients displayed significantly lower recognition of sad and happy emotional faces with respect to PD ones. This applied to global recognition, as well as to low-intensity and high-intensity facial emotion recognition. These results indicate specific impairment of recognition of sad and happy facial emotions in PSP with respect to PD patients. The differences may depend upon diverse involvement of cortical-subcortical loops integrating emotional states and cognition between the two conditions, and might represent a neuropsychological correlate of the apathetic syndrome frequently encountered in PSP.

    Full Text Available Emotion-related areas of the brain, such as the medial frontal cortices, amygdala and striatum are activated during listening to sad or happy music as well as during listening to pleasurable music. Indeed, in music, like in other arts, sad and happy emotions might co-exist and be distinct from emotions of pleasure or enjoyment. Here we aimed at discerning the neural correlates of sadness or happiness in music as opposed those related to musical enjoyment. We further investigated whether musical expertise modulates the neural activity during affective listening of music. To these aims, 13 musicians and 16 non-musicians brought to the lab their most liked and disliked musical pieces with a happy and sad connotation. Based on a listening test, we selected the most representative 18-sec excerpts of the emotions of interest for each individual participant. Functional magnetic resonance imaging (fMRI recordings were obtained while subjects listened to and rated the excerpts. The cortico-thalamo-striatal reward circuit and motor areas were more active during liked than disliked music, whereas only the auditory cortex and the right amygdala were more active for disliked over liked music. These results discern the brain structures responsible for the perception of sad and happy emotions in music from those related to musical enjoyment. We also obtained novel evidence for functional differences in the limbic system associated with musical expertise, by showing enhanced liking-related activity in fronto-insular and cingulate areas in musicians.

    Emotion-related areas of the brain, such as the medial frontal cortices, amygdala, and striatum, are activated during listening to sad or happy music as well as during listening to pleasurable music. Indeed, in music, like in other arts, sad and happy emotions might co-exist and be distinct from emotions of pleasure or enjoyment. Here we aimed at discerning the neural correlates of sadness or happiness in music as opposed those related to musical enjoyment. We further investigated whether musical expertise modulates the neural activity during affective listening of music. To these aims, 13 musicians and 16 non-musicians brought to the lab their most liked and disliked musical pieces with a happy and sad connotation. Based on a listening test, we selected the most representative 18 sec excerpts of the emotions of interest for each individual participant. Functional magnetic resonance imaging (fMRI) recordings were obtained while subjects listened to and rated the excerpts. The cortico-thalamo-striatal reward circuit and motor areas were more active during liked than disliked music, whereas only the auditory cortex and the right amygdala were more active for disliked over liked music. These results discern the brain structures responsible for the perception of sad and happy emotions in music from those related to musical enjoyment.

    Pseudomonas aeruginosa produces increased levels of alginate in response to oxygen-deprived conditions. The regulatory pathway(s) that links oxygen limitation to increased synthesis of alginate has remained elusive. In the present study, using immunofluorescence microscopy, we show that anaerobiosis-induced alginate production by planktonic PAO1 requires the diguanylate cyclase (DGC) SadC, previously identified as a regulator of surface-associated lifestyles. Furthermore, we found that the gene products of PA4330 and PA4331, located in a predicted operon with sadC, have a major impact on alginate production: deletion of PA4330 (odaA, for oxygen-dependent alginate synthesis activator) caused an alginate production defect under anaerobic conditions, whereas a PA4331 (odaI, for oxygen-dependent alginate synthesis inhibitor) deletion mutant produced alginate also in the presence of oxygen, which would normally inhibit alginate synthesis. Based on their sequence, OdaA and OdaI have predicted hydratase and dioxygenase reductase activities, respectively. Enzymatic assays using purified protein showed that unlike OdaA, which did not significantly affect DGC activity of SadC, OdaI inhibited c-di-GMP production by SadC. Our data indicate that SadC, OdaA and OdaI are components of a novel response pathway of P. aeruginosa that regulates alginate synthesis in an oxygen-dependent manner. © 2016 Society for Applied Microbiology and John Wiley & Sons Ltd.

    Subcritical Assembly in Dubna (SAD), a project funded by the International Science and Technology Centre, driven in collaboration with many European partners, may become the first Accelerator Driven Subcritical experiment coupling an existing proton accelerator of 660 MeV with a compact MQX-fuelled subcritical core. The main objective of the SAD experiment is to study physics of Accelerator Driven System ranging from a very deep subcriticality up to keff of 0.98. All experiences with subcriticality monitoring from previous subcritical experiments like MUSE, Yalina and IBR-30 booster mode will be verified in order to select the most reliable subcriticality monitoring technique. Particular attention will be given to validation of the core power-beam current relation. Moreover, some studies have been done to assess possibility of power upgrade for SAD.

    2012-01-01

    Full Text Available Natural habitats on the territory of Novi Sad are almost fully destroyed today, as well as their characteristic plant taxa. The reason for disappearance of natural habitats is the development of suburban communities, which is an irreversible process. Plant taxa, specific for wet, salty, and sandy ecosystems grew on those habitats twenty years ago and earlier. This paper presents the overview of 9 taxa (Suaeda maritima subsp. maritima, Androsace elongata subsp. elongata, Cirsium boujartii subsp. boujartii, Aster sedifolius subsp. canus, Blackstonia perfoliata subsp. serotina, Plantago maritima subsp. maritima, Salvia nutans, Allium angulosum, and Typha schuttleworthii. These taxa presented integral parts of autochthonous flora of Novi Sad. Since some of these taxa were found in the field 21 years ago and some even 93 years ago, they are extinct from the flora of Novi Sad.

    Mood congruence effects have long been studied in younger adults, but not in older adults. Socioemotional selectivity theory (SST) suggests that mood congruence could operate differently in older adults. One hundred and nineteen younger and 78 older adults were randomly assigned to sad or neutral mood inductions, using combined Velten and music induction procedures. Results indicated that during sad mood induction both older and younger adults showed enhanced recall of sad words on delayed word list recall task and in autobiographical memory. However, only older adults displayed mood congruence effects on lexical ambiguity and lower recall of positive words in the word list task. Results provided partial support for developmental effects on mood congruence derived from SST.

    Full Text Available Through X-ray crystallographic fragment screening, 4-bromopyrazole was discovered to be a `magic bullet' that is capable of binding at many of the ligand `hot spots' found in HIV-1 reverse transcriptase (RT. The binding locations can be in pockets that are `hidden' in the unliganded crystal form, allowing rapid identification of these sites for in silico screening. In addition to hot-spot identification, this ubiquitous yet specific binding provides an avenue for X-ray crystallographic phase determination, which can be a significant bottleneck in the determination of the structures of novel proteins. The anomalous signal from 4-bromopyrazole or 4-iodopyrazole was sufficient to determine the structures of three proteins (HIV-1 RT, influenza A endonuclease and proteinase K by single-wavelength anomalous dispersion (SAD from single crystals. Both compounds are inexpensive, readily available, safe and very soluble in DMSO or water, allowing efficient soaking into crystals.

  16. SAD in the Anthropocene: Brenda Hillman’s Ecopoetics of Affect

    Directory of Open Access Journals (Sweden)

    Laurel Peacock

    2012-11-01

    Full Text Available This article focuses on three collections of poetry by California poet Brenda Hillman, Cascadia, Practical Water, and Pieces of Air in the Epic, reading for the ways in which the poems model an affective interrelation between human and environment. These three works each focus on a traditional element (earth, water, air in order to explore its co-constitution with the human, treating the element as active, or, in Jane Bennett’s term, “vibrant matter.” In the Anthropocene, it is no longer an “intentional fallacy” to attribute human emotions to the environment or its elements. Seasonal Affective Disorder (SAD is used throughout the article as a way to conceptualise this interrelation of human with environment; SAD suggests that in this era human and environment alike are disordered. I argue that, rather than staging a lyric subject regarding a landscape, Hillman’s poems create a confusion of subject/object and foreground/background relations in which the origins of affects are impossible to determine and harms circulate. Affect is vital in understanding human motivations in relation to climate change, and Hillman’s ecopoetic practice is an example of how we can shift our understanding of our affective relationship to the environment. Linguistic experimentation can shift awareness toward an understanding of the link between “what it felt like to have been a subject” and “what it felt like to have been earth” as well as what it feels like now to be indeterminately both, intertwined and in crisis.

  17. Modulation of brain resting-state networks by sad mood induction.

    Directory of Open Access Journals (Sweden)

    Ben J Harrison

    Full Text Available BACKGROUND: There is growing interest in the nature of slow variations of the blood oxygen level-dependent (BOLD signal observed in functional MRI resting-state studies. In humans, these slow BOLD variations are thought to reflect an underlying or intrinsic form of brain functional connectivity in discrete neuroanatomical systems. While these 'resting-state networks' may be relatively enduring phenomena, other evidence suggest that dynamic changes in their functional connectivity may also emerge depending on the brain state of subjects during scanning. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we examined healthy subjects (n = 24 with a mood induction paradigm during two continuous fMRI recordings to assess the effects of a change in self-generated mood state (neutral to sad on the functional connectivity of these resting-state networks (n = 24. Using independent component analysis, we identified five networks that were common to both experimental states, each showing dominant signal fluctuations in the very low frequency domain (approximately 0.04 Hz. Between the two states, we observed apparent increases and decreases in the overall functional connectivity of these networks. Primary findings included increased connectivity strength of a paralimbic network involving the dorsal anterior cingulate and anterior insula cortices with subjects' increasing sadness and decreased functional connectivity of the 'default mode network'. CONCLUSIONS/SIGNIFICANCE: These findings support recent studies that suggest the functional connectivity of certain resting-state networks may, in part, reflect a dynamic image of the current brain state. In our study, this was linked to changes in subjective mood.

    Single-wavelength anomalous dispersion of S atoms (S-SAD) is an elegant phasing method to determine crystal structures that does not require heavy-atom incorporation or selenomethionine derivatization. Nevertheless, this technique has been limited by the paucity of the signal at the usual X-ray wavelengths, requiring very accurate measurement of the anomalous differences. Here, the data collection and structure solution of the N-terminal domain of the ectodomain of HCV E1 from crystals that diffracted very weakly is reported. By combining the data from 32 crystals, it was possible to solve the sulfur substructure and calculate initial maps at 7 Å resolution, and after density modication and phase extension using a higher resolution native data set to 3.5 Å resolution model building was achievable.

    Triacylglycerol lipases (EC 3.1.1.3) are present in many different organisms including animals, plants, and microbes. Lipases catalyze the hydrolysis of long-chain triglycerides into fatty acids and glycerol at the interface between the water insoluble substrate and the aqueous phase. Lipases can also catalyze the reverse esterification reaction to form glycerides under certain conditions. Lipases of microbial origin are of considerable commercial interest for wide variety of biotechnological applications in industries, including detergent, food, cosmetic, pharmaceutical, fine chemicals, and biodiesel. Nowadays, microbial lipases have become one of the most important industrial enzymes. PEL (Penicillium expansum lipase) is a fungal lipase from Penicillium expansum strain PF898 isolated from Chinese soil that has been subjected to several generations of mutagenesis to increase its enzymatic activity. PEL belongs to the triacylglycerol lipases family, and its catalytic characteristics have been studied. The enzyme has been used in Chinese laundry detergent industry for several years (http://www.leveking.com). However, the poor thermal stability of the enzyme limits its application. To further study and improve this enzyme, PEL was cloned and sequenced. Furthermore, it was overexpressed in Pichia pastoris. PEL contains GHSLG sequence, which is the lipase consensus sequence Gly-X1-Ser-X2-Gly, but has a low amino acid sequence identities to other lipases. The most similar lipases are Rhizomucor miehei (PML) and Rhizopus niveus (PNL) with a 21% and 20% sequence identities to PEL, respectively. Interestingly, the similarity of PEL with the known esterases is somewhat higher with 24% sequence identity to feruloyl esterase A. Here, we report the 1.3 {angstrom} resolution crystal structure of PEL determined by sulfur SAD phasing. This structure not only presents a new lipase structure at high resolution, but also provides a structural platform to analyze the published

The present study aims to examine the convergent validity of the Brazilian version of the Schedule for Affective Disorders and Schizophrenia for School-Age Children/Present and Lifetime Version (K-SADS-PL by comparison with the Child Behavior Checklist (CBCL, a parental screening measure for child/adolescent emotional/behavior problems. Methods An experienced child psychiatrist blind to CBCL results applied the K-SADS-PL to a consecutive sample of 78 children (6-14 years referred to a public child mental health outpatient clinic (response rate = 75%. Three K-SADS-PL parameters were considered regarding current disorders: parent screen interview rates, clinician summary screen interview rates, and final DSM-IV diagnoses. Subjects were classified according to the presence/absence of any affective/anxiety disorder, any disruptive disorder, and any psychiatric disorder based on K-SADS-PL results. All subjects obtained T-scores on CBCL scales (internalizing, externalizing, total problems. Results Significant differences in CBCL mean T-scores were observed between disordered and non-disordered children. Compared to children who screened negative, children positive for any affective/anxiety disorder, any disruptive disorder, and any psychiatric disorder had a higher internalizing, externalizing and total problem T-score mean, respectively. Highly significant differences in T-score means were also found when examining final diagnoses, except for any affective/anxiety disorder. Conclusions Evidence of convergent validity was found when comparing K-SADS-PL results with CBCL data.

    2016-09-29

    The Bi-State distinct population segment (DPS) of greater sage-grouse (Centrocercus urophasianus) that occurs along the Nevada–California border was proposed for listing as threatened under the Endangered Species Act (ESA) by the U.S. Fish and Wildlife Service (FWS) in October 2013. However, in April 2015, the FWS determined that the Bi-State DPS no longer required protection under the ESA and withdrew the proposed rule to list the Bi-State DPS (U.S. Fish and Wildlife Service, 2015). The Bi-State DPS occupies portions of Alpine, Mono, and Inyo Counties in California, and Douglas, Esmeralda, Lyon, Carson City, and Mineral Counties in Nevada. Unique threats facing this population include geographic isolation, expansion of single-leaf pinyon (Pinus monophylla) and Utah juniper (Juniperus osteosperma), anthropogenic activities, and recent changes in predator communities. Estimating population vital rates, identifying seasonal habitat, quantifying threats, and identifying movement patterns are important first steps in developing effective sage-grouse management and conservation plans. During 2011–15, we radio- and Global Positioning System (GPS)-marked (2012–14 only) 44, 47, 17, 9, and 3 sage-grouse, respectively, for a total of 120, in the Pine Nut Mountains Population Management Unit (PMU). No change in lek attendance was detected at Mill Canyon (maximum=18 males) between 2011 and 2012; however, 1 male was observed in 2014 and no males were observed in 2013 and 2015. Males were observed near Bald Mountain in 2013, making it the first year this lek was observed to be active during the study period. Males were observed at a new site in the Buckskin Range in 2014 during trapping efforts and again observed during surveys in 2015. Findings indicate that pinyon-juniper is avoided by sage-grouse during every life stage. Nesting females selected increased sagebrush cover, sagebrush height, and understory horizontal cover, and brood-rearing females selected similar areas

    2011-04-25

    The relationship between the "passions" (emotions or feelings) and psychopathology has been a constant throughout the history of medicine. In this context, melancholy was considered a perversion of the soul (corruption of the passions). One of the most influential authors on this subject was René Descartes, who discussed it in his work The Treatise on the Passions of the Soul (1649). Descartes believed that "passions" were sensitive movements that the soul experienced due to its union with the body (res extensa). According to this theory, the soul was located in the pineal gland, where it was actively involved in overseeing the functions of the "human machine" and kept its dysfunctions under control, by circulating animal spirits. Descartes described sadness as one of "the six primitive passions of the soul", which leads to melancholy if not remedied. Cartesian theories had a great deal of influence on the way that mental pathologies were considered throughout the entire 17th century (Spinoza, Willis, Pitcairn) and during much of the 18th century (Le Cat, Tissot). From the 19th century onwards, emotional symptomatology finally began to be used in diagnostic criteria for mood disorders.

    Full Text Available Assessment of pollutant emissions is a prerequisite for planning and development of sustainable urban transport systems. Majority of extant studies on sustainable urban transport is focused on pollution caused by urban passenger transport, with marked paucity of literature on the impact of urban freight transport. To partly bridge this gap, the paper objective is the impact assessment of selected regulative measures, i.e. fleet renewal on freight transport emissions. We used the case of Novi Sad to estimate the potential impact of selected restrictive measures on the external freight transport air pollution. To the best of our knowledge, this is one of the first studies on impact of urban freight transport on the air pollution in the cities in the Balkan region. Several research findings are of interest. Firstly, the analysis of particular gas emissions reveals expected overall positive effects of the fleet renewal in most of cases. Still, the total amount of same emissions hardly increase, so this particular measure is not enough to reach the ambitious EU strategy goals concerned with sustainable urban freight transport. Further, some negative impacts of restrictive measures on gas emissions were also recorded and discussed. The observed complex impact of restrictive measures on urban freight air pollution indicates that urban freight transport planning and modeling requires a comprehensive database, clear goals and higher priority of environmental criterion in traffic planning. Our results and recommendations may be useful for scholars, urban transport planners, policy makers and practitioners.

    Full Text Available are valuable source of vitamins, minerals and fibers important for healthy human nutrition. However, an increased level of heavy metals in vegetables has been noticed in recent years. This study was conducted with an aim to analyze content of heavy metals, cadmium (Cd, lead (Pb, and chromium (Cr in 11 vegetable species which are the most common in human diet. Vegetables were collected from three green markets (Limanska, Futoška and Riblja pijaca in Novi Sad, during September and October, from 2009 to 2011. Heavy metal contents were analyzed in edible parts of tomato, potato, spinach, onion, beetroot, parsley, parsnip, carrot, cauliflower, pepper and broccoli using atomic absorption spectrophotometer (Varian, AAS 240FS. The results showed statistically significant differences in element concentrations among analyzed vegetables. In general, the highest metal pollution was observed in the year of 2011. Spinach was found to contain the highest metals content - 0.89 μg/g for Cd, 5.81 μg/g for Pb, and 3.67 μg/g for Cr. According to Serbian official regulations, 18.18% of all analyzed species exceeded maximum permissible level for Cd, 9.09% for Pb, while for Cr these limits are not defined. Elevated content of heavy metals in vegetables might be related to soil contamination, atmospheric depositions during transportation and marketing. Thus, a continuous monitoring of vegetables on markets should be performed in order to prevent potential health risks to consumers.

    2010-07-01

    Full Text Available The three main cannabinoids Δ9-tetrahydrocannabinol (Δ9-THC, cannabidiol (CBD and cannabinol (CBN were identified and determined quantitatively using a GCD (GC-EI instrument in 280 samples of illicit herbal cannabis, seized by the Police authorities in Novi Sad, during 2008. The samples were sent to the Institute of Forensic Medicine, Clinical Center Vojvodina, for forensic chemical analysis. The cannabinoid content of the samples enabled the classification of the cannabis into three chemical phenotypes and the differentiation into drug and textile-cannabis, using the Waller classification index. This differentiation has great forensic significance in the classification of certain cases as a criminal action. The experimental results showed that the Δ9-THC content in illicitly circulated cannabis slightly decreased from January to December 2008, as did the quality of the drug-cannabis. The reasons for the quality variations could lie in the geographical origin of the cannabis plants, the conditions of plants storage, various parts of the plants in samples and the time elapsed between harvesting and chemical analysis.

    Full Text Available Fungal spores can cause a range of health problems in humans such as respiratory diseases and mycotoxicoses. Since children are the most vulnerable, the presence of fungal spores in the facilities of preschool and school institutions should be investigated readily. In order to estimate air contamination by fungal spores, air sampling was conducted in eight facilities of the preschool institution in Novi Sad during February and March, 2007. Sedimentation plate method was used for the detection of viable fungal spores, mostly being members of subdv. Deuteromycota (Fungi imperfecti. In 32 samples a total of 148 colonies were developed, among which five genera were identified: Penicillium, Cladosporium, Aspergillus, Alternaria and Acremonium while non-sporulating fungal colonies were labeled as sterile mycelia. Most frequently recorded genera were Penicillium with 46 colonies and Cladosporium with 44 colonies. The genera Aspergillus and Alternaria were represented with 3 colonies each and Acremonium with only 1 colony. The greatest number of colonies emerged in the samples from the day care facilities “Vendi” (58 colonies and “Panda” (49 colonies. Most diverse samples were obtained from the day care center “Zvončica”, with presence of all identified genera. These results showed notable presence of fungal spores in the indoor air of Preschool institution facilities and indicated the need for further, more complete seasonal research. Obtained information is considered useful for the evaluation of potential mycofactors that endanger health of children. [Projekat Ministarstva nauke Republike Srbije, br. III43002

    Full Text Available The collection of oil species in Novi Sad contains 12 species represented with 1-4 cultivars or landraces. In the continuous work on this collection in the sense of breeding of some of those species and their usage as a source of 'desirable genes' we analyzed pollen grain morphology (shape and size, as well as pollen viability. To determine mentioned pollen traits we used Axiovert 40C microscope together with a software package (AxioVision LE; Rel.4.3. for measurement of pollen length and width. Pollen viability was determined using a staining method (ALEXANDER, 1969. The results showed that species differ by pollen grain shape (round, egg-shaped, triangular and rod as well as by shape of exine (thick and spiky, thick to thin. In some species there was a specific number of apertures present (1-11. The size of viable pollen grains ranged from 29,10/12,58μ (coriander to 176,63/169,94μ (oil gourd, while non-viable pollen grains were always smaller (27,27/10,97μ to 119,62/100,86μ at the same plant species. Pollen viability of most species was around 80%. Lowest pollen viability was found in white flax (56,98%, and the highest in oil pumpkin (91,43%.

    Full Text Available The aim of this study was to determine the anthropological status of adult females and the prevalence of females with potential health risk using the indices of obesity. The anthropological study was conducted from 2011 to 2013 in Novi Sad, (the north of Serbia. The tested group consisted of 310 women, with mean age 41.42±6.86, involved in the project "The impact of physical activity on the risk factors in the working population." Nutritional condition was determined using the body mass index (BMI kg/m2 , while the waist circumference and WHR were used for assessing the central obesity. According to the average BMI, the younger females are predominantly with normal weight, while higher percent of older females is characterised with pre-obesity. In total, 45.85% of females are with excessive body weight, 34.62% of them being classified as overweight and 11.23% as obese. Central obesity is more frequent in older females aged up to 40. Potential health risk increases with age, and very high health risk from abdominal and overall obesity was observed in 6.25% of younger and 13,25% of older women. The data therefore point to the necessity of continuous monitoring and a combination of existing programs with other forms of organized physical activity.

    2013-03-04

    This paper, proposes a novel solution for a stereo vision machine based on the System-on-Programmable-Chip (SoPC) architecture. The SOPC technology provides great convenience for accessing many hardware devices such as DDRII, SSRAM, Flash, etc., by IP reuse. The system hardware is implemented in a single FPGA chip involving a 32-bit Nios II microprocessor, which is a configurable soft IP core in charge of managing the image buffer and users' configuration data. The Sum of Absolute Differences (SAD) algorithm is used for dense disparity map computation. The circuits of the algorithmic module are modeled by the Matlab-based DSP Builder. With a set of configuration interfaces, the machine can process many different sizes of stereo pair images. The maximum image size is up to 512 K pixels. This machine is designed to focus on real time stereo vision applications. The stereo vision machine offers good performance and high efficiency in real time. Considering a hardware FPGA clock of 90 MHz, 23 frames of 640 × 480 disparity maps can be obtained in one second with 5 × 5 matching window and maximum 64 disparity pixels.

    Full Text Available The paper presents results of the analysis of illicit synthetic drugs in the form of tablets distributed under the name "Ecstasy", seized by the police in the broader area of Novi Sad 2004. A huge number of tablets has been analyzed (n=121, of various colours and with impressed symbols from the total amount of 93 seizures, which totally amounted to 1458 tablets. Regarding the number of seizures ecstasy (3,4-methylendioxy-N-meth-yl-amphetamine - MDMA is dominant among all, and according to the quantity of seized tablets it is amphetamine (AP, while other amphetamine-type drugs (methamphetamine MA 3,4-methylendioxiamphetamine - MDA, 3,4-methylendioxi-N-ethyl-amphetamine MDEA have been found in rather small quantities and very rarely. Tablets mostly contain caffeine as an additive. In the analytical procedure, the samples of tablets were subjected to liquid-liquid extraction and afterwards analyzed on the GCD (GC-EI Hewlett-Packard instrument. The method is fast reliable and reproducible for the analysis of amphetamine, methamphetamine MDA, MDMA, MDEA, as well as various additives in the samples of seized tablets.

    We provide a detailed description of selenobiotinyl-streptavidin (Se-B SA) co-crystal datasets recorded using the Coherent X-ray Imaging (CXI) instrument at the Linac Coherent Light Source (LCLS) for selenium single-wavelength anomalous diffraction (Se-SAD) structure determination. Se-B SA was chosen as the model system for its high affinity between biotin and streptavidin where the sulfur atom in the biotin molecule (C10H16N2O3S) is substituted with selenium. The dataset was collected at three different transmissions (100, 50, and 10%) using a serial sample chamber setup which allows for two sample chambers, a front chamber and a back chamber, to operate simultaneously. Diffraction patterns from Se-B SA were recorded to a resolution of 1.9 Å. The dataset is publicly available through the Coherent X-ray Imaging Data Bank (CXIDB) and also on LCLS compute nodes as a resource for research and algorithm development.

    Through X-ray crystallographic fragment screening, 4-bromopyrazole was discovered to be a `magic bullet' that is capable of binding at many of the ligand `hot spots' found in HIV-1 reverse transcriptase (RT). The binding locations can be in pockets that are `hidden' in the unliganded crystal form, allowing rapid identification of these sites forin silicoscreening. In addition to hot-spot identification, this ubiquitous yet specific binding provides an avenue for X-ray crystallographic phase determination, which can be a significant bottleneck in the determination of the structures of novel proteins. The anomalous signal from 4-bromopyrazole or 4-iodopyrazole was sufficient to determine the structures of three proteins (HIV-1 RT, influenza A endonuclease and proteinase K) by single-wavelength anomalous dispersion (SAD) from single crystals. Both compounds are inexpensive, readily available, safe and very soluble in DMSO or water, allowing efficient soaking into crystals.

    Full Text Available Motivation is a highly individual matter. It depends not only on the actual needs of the employee, but also on his personality, experience and scale of values. The employee work motivation directly influences the company productivity. In order to achieve the maximum level of motivation, managers need to know their needs and motivating factors of employees they supervise. Money is the key motivation factor for people, who need money to maintain their own existence. Non-financial factors of motivation also have a growing importance on the individual employee motivation. The main objective of this paper is to determinate the main intrinsic and extrinsic factors of employee motivation, and its effect on the provided service quality in the "Postal Traffic - Department in Novi Sad". The research is based on Herzberg's Two-factor theory. The results of the research showed, that majority of the factors is rated fairly high. The "Salary" is the lowest rated factor, while the factor "Colleagues" have the highest effect on employee motivation.

  7. What else do you feel when you feel sad? Emotional overproduction, neuroticism and rumination.

    Numerous experimental and naturalistic studies have shown the relevant role of ruminative styles in the onset, duration and severity of depressive episodes. Recent research has increasingly focused on the precursors of these ruminative responses. Neuroticism has been found to be closely related to ruminative styles, but the nature of this relationship is unknown. Across three studies, we explored the role of emotional overproduction, conceptualized as the tendency to simultaneously experience an elevated number of negative emotions and feelings during sad episodes. Study 1 showed that emotional overproduction is independently and strongly associated with ruminative styles. Furthermore, emotional overproduction was found to mediate the relationship between neuroticism and ruminative styles. Study 2 replicated these findings in a large community sample even after controlling for mood, personality, and other emotion-related variables. In Study 3, we conducted a laboratory study to increase the internal and external validity of our findings. Implications for personality, for coping and stress literature, and for clinical research and treatment are suggested.

  8. Age-Related Response Bias in the Decoding of Sad Facial Expressions

    Full Text Available Recent studies have found that age is negatively associated with the accuracy of decoding emotional facial expressions; this effect of age was found for actors as well as for raters. Given that motivational differences and stereotypes may bias the attribution of emotion, the aim of the present study was to explore whether these age effects are due to response bias, that is, the unbalanced use of response categories. Thirty younger raters (19–30 years and thirty older raters (65–81 years viewed video clips of younger and older actors representing the same age ranges, and decoded their facial expressions. We computed both raw hit rates and bias-corrected hit rates to assess the influence of potential age-related response bias on decoding accuracy. Whereas raw hit rates indicated significant effects of both the actors’ and the raters’ ages on decoding accuracy for sadness, these age effects were no longer significant when response bias was corrected. Our results suggest that age effects on the accuracy of decoding facial expressions may be due, at least in part, to age-related response bias.

    Although many studies have examined the neural basis of empathy, relatively little is known about how empathic processes are affected by different attentional conditions. Thus, we examined whether instructions to empathize might amplify responses in empathy-related regions and whether cognitive load would diminish the involvement of these regions. Thirty-two participants completed a functional magnetic resonance imaging session assessing empathic responses to individuals experiencing happy, sad, and anxious events. Stimuli were presented under three conditions: watching naturally, actively empathizing, and under cognitive load. Across analyses, we found evidence for a core set of neural regions that support empathic processes (dorsomedial prefrontal cortex, DMPFC; medial prefrontal cortex, MPFC; temporoparietal junction, TPJ; amygdala; ventral anterior insula, AI; and septal area, SA). Two key regions-the ventral AI and SA-were consistently active across all attentional conditions, suggesting that they are automatically engaged during empathy. In addition, watching vs. empathizing with targets was not markedly different and instead led to similar subjective and neural responses to others' emotional experiences. In contrast, cognitive load reduced the subjective experience of empathy and diminished neural responses in several regions related to empathy and social cognition (DMPFC, MPFC, TPJ, and amygdala). The results reveal how attention impacts empathic processes and provides insight into how empathy may unfold in everyday interactions.

    Full Text Available The beginning of the 21st century was marked by significant socio-economic changes in Serbia, which influenced urban environment and development strategies. Novi Sad, the capital of the Serbian province of Vojvodina, also followed this pattern, adjusting to the new social and spatial dynamic. The shift from a socialist to a neo-liberal model of planning was visible in different spheres - the system of stakeholders was altered, public funds were substituted with small private investors, while existing regulations were either overlooked or interpreted in a questionable manner. Simultaneously, the newly established real estate market mostly focused on the areas around the traditional urban core which underwent a process of quasi-regeneration. Used only as an opportunity for new speculative development, it did not have any respect for either tangible or intangible heritage. However, a decline in real estate development (since 2009 has created a setting for a different planning approach to include consideration of problems of heritage areas. Considering the socio-economic background of recent urban transformations in Novi Sad’s inner-city neighbourhoods, this article analyses the context of the problem, provides recommendations for improvements in the approach to planning, and introduces guidelines and rules for site-sensitive urban and architectural design.

    2016-08-01

    Full Text Available The persistence of negative moods (sadness and anxiousness induced by three visual Mood Induction Procedures (MIP was investigated. The evolution of the mood after the MIP was monitored for a period of 8 minutes with the Self-Assessment Manikin (every 2 minutes and with recordings of skin conductance level (SCL and electrocardiography (ECG. The SAM pleasure ratings showed that short and longer film fragments were effective in inducing a longer lasting negative mood, whereas the negative mood induced by the IAPS slideshow was short lived. The induced arousal during the anxious MIPs diminished quickly after the mood induction; nevertheless, the SCL data suggest longer lasting arousal effects for both movies. The decay of the induced mood follows a logarithmic function; diminishing quickly in the first minutes, thereafter returning slowly back to baseline. These results reveal that caution is needed when investigating the effects of the induced mood on a task or the effect of interventions on induced moods, because the induced mood diminishes quickly after the mood induction.

    Full Text Available In order to ensure the satisfaction of the users, the hotels are expanding their offer with various sports and recreational facilities. The basic requirements for the realisation of the sports and recreational programmes are expert staff, adequate space and interesting programme. The aim of this paper is to determine the satisfaction of the users with certain aspects of the quality of the sports and recreational offer in four Novi Sad hotels. There were 98 respondents involved in the research. The results showed that there are significant differences in the evaluation of the quality in terms of prices, working hours, programme content and the hotel accessibility. The results also showed that the hotel rank is not related to the users’ satisfaction with the quality of the sports and recreational facility offer. Constant innovations of the locales and their equipment, the personalisation of the sports and recreational programmes, hiring expert staff and sports animators but also adjusting all of the offer elements to the local population is essential to achieve users’ satisfaction with the sports and recreational offer and generate the income for the organisation – hotel.

    2013-04-01

    The present study examined the relationship between self-generated emotions and physical performance. All participants took part in five emotion induction conditions (happiness, anger, anxiety, sadness, and an emotion-neutral state) and we investigated their influence on the force of the finger musculature (Experiment 1), the jump height of a counter-movement jump (Experiment 2), and the velocity of a thrown ball (Experiment 3). All experiments showed that participants could produce significantly better physical performances when recalling anger or happiness emotions in contrast to the emotion-neutral state. Experiments 1 and 2 also revealed that physical performance in the anger and the happiness conditions was significantly enhanced compared with the anxiety and the sadness conditions. Results are discussed in relation to the Lazarus (1991, 2000a) cognitive-motivational-relational (CMR) theory framework.

    Full Text Available This interdisciplinary study applies the theatrical theories of stage genres to examples of the early sound cinema, the 1930 Hollywood musicals Puttin’ on the Ritz (starring Harry Richman, and with songs by Irving Berlin and Free and Easy (starring Buster Keaton. The discussion focuses on the phenomenon of the sad clown as a symbol of tragicomedy. Springing from Rick Altman’s delineation of the “sad clown” sub-subgenre of the show musical subgenre, outlined in The American Film Musical, this article shows that, in these seminal movie musicals, naïve melodrama and “gag” comedy coexist with the tonalities, structures, philosophy, and images of the sophisticated genre of tragicomedy, including by incorporating the grotesque into the mise en scene of their musical production numbers.

    In the mid-twentieth century, the health care of women and children was inadequate in the post-war Yugoslavia, including the city of Novi Sad, due to the severe post-war reality: poverty in the devastated country, shortage of all commodities and services and especially of medical supplies, equipment and educated staff. OUT-OF-HOSPITAL MATERNITY UNIT: One of the serious problems was parturition at home and morbidity and mortality of the newborns and women. Soon after the World War II the action programme of improving the women's health was realized on the state level by establishing out-of-hospital maternity units but under the expert supervision. The Maternity unit at 30 Ljudevita Gaja Street in Novi Sad played a great role in providing skilled birth attendance at mainly normal deliveries. With a minimal number of medical staff and modest medical equipment, about 2000 healthy babies were born in this house. After 5 years of functioning in that way, this unit was transformed into the Motherhood Home and became a social and medical institution for pregnant women and new mothers. Regardless of the redefined organization concept the curative and preventive health care as well as women and children social protection programmes were provided successfully for the next 12 years. Although the Motherhood Home was moved into the Women Health Centre of Novi Sad and later into the former Maternity Hospital in Sremski Karlovci, its great importance for women and children's health care remained unchanged. In 1979 the overall social situation and mostly economic issues led to its closing. The house in Gajeva Street is now used as the municipality office. However, this house with its story recommends itself to become a house for a special social function, such as a museum of medical history of Novi Sad. A small investment could make it possible to collect, preserve and display the valuable records of our past, which is something we do owe to the generations to come.

A use of Novalis linear accelerator 6 MV photon beams. In general, IMRS were 25 patients with small field size. The selected patients were divided into three groups on the basis of the field size. SAD was changed from 80 to 130 cm and field size to determine the dose distribution to the change, each dose was measured using MatriXX Phantom. Analysis of measured values obtained from the program for each patient through the treatment planning system comparison and analysis of the dose distribution and gamma values were expressed. SAD 80, 100, and 120 cm in size in the gamma value to the investigation of patients less than 3 cm{sup 2} average 0.939, 0.969, and 0.979, respectively. Patients with more than 5 cm{sup 2} 0.962, 0.983, and 0.988, respectively. 5 cm{sup 2} or more patients 0.982, 0.990, and 0.992, respectively. The error rate of less than 3 cm{sup 2} field size is increased rapidly. If the field size is increased, resolution is increased by 2D ion chambers. It has been approved that it can be credible if it is around 3 cm{sup 2} when measuring dose distribution using MatriXX. Adjusting geometric field size by changing SAD is likely to be very useful when you measure dose distribution using MatriXX.

    Herbal hepatotoxicity is a rare and poorly described disease because reported cases are mostly scattered and lack an appropriate causality assessment. We now describe in detail the clinical picture of herbal hepatotoxicity by extracts of Greater Celandine (GC), syn. Chelidonium majus L. from the Papaveraceae family, which contain more than 20 ingredients including various biologically active isoquinoline alkaloids. For this purpose, we analyzed and reviewed published cases of 16 patients from various European countries. In all patients, herbal hepatotoxicity was of probable and highly probable causality for GC, using the original and updated scale of CIOMS (Council for International Organizations of Medical Sciences). GC associated hepatotoxicity usually has an acute clinical course exhibiting a hepatocellular pattern of injury and is correlated to an idiosyncratic reaction with its metabolic subtype. Jaundice combined with high values of serum aminotransferases was present in virtually all cases with favourable outcome despite severe clinical course. In conclusion, GC hepatotoxicity is a typical herbal hepatotoxicity with a sound causality track for GC, but there is uncertainty regarding the respective causative compound(s). The present detailed review of GC hepatotoxicity may serve as an example for clinical causality assessments of future cases of liver injury due to other herbs.

    Music is known to convey and evoke emotional states. Musical training has been argued to lead to changes in neural architecture and enhanced processing of emotions. It is not clear, however, whether musical training is also associated with changes in behavioral and neural responses to musically conveyed discrete emotions. Using functional magnetic resonance imaging, we investigated the responses to three musically conveyed emotions (happiness, sadness, fear) in a group of musicians and a group of non-musicians. We find that musicians rate sadness and fear as significantly more arousing than non-musicians, and that musical training is associated with specific neural activations: In response to sadness expressed in music, musicians show activation increases in the right prefrontal cortex, specifically in the superior and middle frontal gyri. In response to fear, musicians show activation increases in the right parietal cortex, specifically in the supramarginal and inferior parietal gyri. No specific activations were observed in response to happiness. Our results highlight the strong association between musical training and altered processing of "negative" emotions on both the behavioral and on the neural level.

    Full Text Available Background: The impact of remittances on health problems like depression among immigrants is understudied. Yet immigrants may be particularly emotionally vulnerable to the strains and benefits of providing remittances. Objective: This study examines the association between sending remittances and major depressive episode (MDE and sadness among legal immigrants in the United States. Methods: Cross-sectional data (N=8,236 adults come from the New Immigrant Survey (2003-2004, a representative sample of new U.S. permanent residents. Results: In logistic regression models, immigrants who remitted had a higher risk of MDE and sadness compared to those who did not, net of sociodemographic and health factors. For remitters (N=1,470, the amount of money was not significantly linked to MDE but was associated with a higher risk of sadness among refugees/asylees compared to employment migrants. Conclusions: Among socioeconomically vulnerable migrants such as refugees/asylees, sending remittances may threaten mental health by creating financial hardship. Initiatives that encourage economic stability for migrants may protect against depression.

    Full Text Available Introduction. Despite a large number of modern contraceptive methods available in the market today, numerous studies have shown insufficient awareness of young women about these forms for birth control. The aim of this study was to compare characteristics of common use of contraceptives as well as the awareness of hormonal contraception among female students of the Faculty of Medicine and the Faculty of Technical Sciences in Novi Sad. Materials and Methods. In the study which was conducted in 2012 240 female students of the Faculty of Medicine and the Faculty of Technical Sciences participated. The average age of students of the Faculty of Medicine and the Faculty of Technical Sciences was 24.06 ± 3.24 and 22.72 ± 0.90 years, respectively. They completed an anonymous questionnaire, which consisted of three parts. The first part comprised general questions, the second part included characteristics of the sexual life of students and their contraceptive habits, while in the third part students were asked to evaluate the accuracy of statements about hormonal contraception. The obtained data were statistically processed by using appropriate methods. Results. The average age when the students of the Faculty of Medicine and the Faculty of Technical Sciences had the first sexual intercourse was 18.74 ± 2.61 and 18.75 ± 2.59, respectively. One third of students from both faculties (30.91% from the Faculty of Medicine and 35% from the Faculty of Technical Sciences had only one sexual partner. Modern contraception was used by 83.64% of the medical students and by 80% of those from the Faculty of Technical Sciences. Contraception was used regularly by 54.54% of the medical students and 43% of those from the Faculty of Technical Sciences. The most frequently applied contraceptive method was condom (90% of the medical students and 93% of the Faculty of Technical Sciences students, respectively.

    Dysregulation of the autonomic nervous system (ANS) has been well documented in individuals diagnosed with a range of psychological disorders, including generalized anxiety disorder (GAD) and major depressive disorder (MDD). Moreover, these disorders both confer an increased risk of cardiovascular disease—which may relate to increased sympathetic and decreased parasympathetic tone. Extant research has indicated a reduction in autonomic flexibility in GAD, and while reduced flexibility has also been seen in MDD, the specific physiological alterations have been more difficult to categorize due to methodological limitations, including high co-morbidity rates with anxiety disorders. Prior studies have largely assessed autonomic functioning in stress paradigms or at the trait level, yet to date, no research has investigated the ANS during a diagnostic interview, a ubiquitous task employed in both research and clinical settings. In this study we sought to identify physiological differences in both branches of the ANS across diagnostic categories in the context of a diagnostic interview. Participants (n = 82) were administered a structured clinical interview, during which heart rate (HR), respiratory sinus arrhythmia (RSA) and pre-ejection period (PEP) were recorded in participants carrying a diagnosis of GAD (n = 34), MDD (n = 22), Social Anxiety Disorder (SAD; n = 15) and healthy controls (n = 27). Person-specific linear regression models were employed to assess the level and slope for HR, RSA and PEP throughout the course of the interview. A multivariate analysis of variance (MANOVA) model was conducted to baseline differences in HR, RSA and PEP between diagnostic groups. Multiple regression models were then conducted to differences in slope of HR, RSA and PEP throughout the course of the interview amongst diagnostic groups, including both suppression and worry as moderators. Results indicated significant increases in RSA throughout the interview in MDD (p = 0

    Full Text Available This study addresses the recent climatology of hail occurrence in the Greater Metropolitan Severe Thunderstorm Warning Area (GMSTWA of New South Wales, Australia, which is a sprawling suburban area, with a population of nearly 4.7 million and one of Australia's largest metropolis. The main objective is to highlight the recent temporal-spatial fluctuations of hailstone frequencies and magnitudes for each of recognized and vastly inhabited Local Government Areas (LGAs. The relevant hail event data from 1989 to 2013 were initially derived from the severe storm archive of Australian Bureau of Meteorology. A climatologically oriented GIS technique was applied in the examining and mapping procedure of all hail events and hail days reported throughout the study area. By applying a specific criterion, all severe hails (defined as 2 cm or more in diameter were cautiously selected and then imported into the ArcGIS software for relevant analysis. Appropriate data layers were stored in a unique database to allow logical integration of the data directly into some geoprocessing functions, mainly for querying, analyzing and mapping purposes in a model-builder setting. The database includes 357 hailstones with sizes 2–11 cm and occurred in 169 hail days across the region during the past 25 years. The models have established that hailstones are neither temporally nor spatially uniform in magnitude throughout the study area. Temporal analysis indicated that most of hail events occurred predominately in the afternoons with peak time of 1–5 p.m. EST. They were particularly common in spring and summer, and reached maximum frequency in November and December. There was an average of 14.3 events each year, but a significant decreasing trend in terms of hail frequency and associated magnitude in the recent years has been identified. In turn, spatial models also established three main distribution patterns over the study area, which include the Sydney Metropolitan

    Proximal femoral fractures are frequently encountered in the emergency department (ED). Prompt diagnosis is paramount as delay will exacerbate the already poor outcomes associated with these injuries. In cases where radiography is negative but clinical suspicion remains high, magnetic resonance imaging (MRI) is the study of choice as it has the capability to depict fractures which are occult on other imaging modalities. Awareness of a particular subset of proximal femoral fractures, namely greater trochanteric fractures, is vital for both radiologists and clinicians since it has been well documented that they invariably have an intertrochanteric component which may require surgical management. The detection of intertrochanteric or cervical extension of greater trochanteric fractures has been described utilizing MRI but is underestimated with both computed tomography (CT) and bone scan. Therefore, if MRI is unavailable or contraindicated, the diagnosis of an isolated greater trochanteric fracture should be met with caution. The importance of avoiding this potential pitfall is demonstrated in the following case of an elderly woman with hip pain and CT demonstrating an isolated greater trochanteric fracture who subsequently returned to the ED with a displaced intertrochanteric fracture.

For the merged group, sleepiness (Epworth Sleepiness Scale, fatigue (fatigue questionnaire, and health-related quality of life (SF-36 were improved at posttreatment, and results were maintained at the one-month followup. Three distinct subgroups had a high level of fatigue in common, while the level of excessive daytime sleepiness and depressed mood differed between the subgroups. Over time, all subgroups improved following ten days treatment in a light room. Conclusion. Fatigue, excessive daytime sleepiness, and health-related quality of life improve in a similar way as depressed mood following treatment with bright light. The treatment was effective irrespective of the severity of the disorder, that is, for persons with SAD and subsyndromal SAD.

    This article describes the actions among urban environmental, management, and development planners in Greater Johannesburg, South Africa. Initiatives, such as the Healthy Cities Project and Model Communities, are being integrated into an environmental management and development approach that attains the goals of Agenda 21. Greater Johannesburg has housing shortages and homelessness. Priority needs include the areas of housing, water, electricity, public transportation, and sanitation. Clean water and air are inequitably distributed. Other key environmental problems include illegal dumping, inadequate waste disposal, poor environmental hygiene in overcrowded inner city areas, lack of open spaces, flooding, and water scarcities. The newly formed metropolitan authority offers opportunities to improve coordination and integration of environmental problems. Stakeholders from government at all levels, politicians, nongovernmental organizations, and the business sector formed an intersectoral, interdepartmental environment management committee in 1995. Stakeholders will integrate Agenda 21 within broader urban development plans and processes. The executive committee and the full council approved a set of guiding principles on environmental policy and an administrative framework for management. Four workshops were held to ensure a participatory consultation process in 1995. The WHO Collaborating Center for Urban Health will be used to facilitate the work of the Greater Johannesburg Metropolitan Council. Changes are being made in the way local governments work.

    Why are people with low self-esteem (LSE) less motivated than people with high self-esteem (HSE) to improve sad moods? The present research examined whether feelings of personal deservingness contribute to this difference. Four experiments with undergraduate participants involved a sad mood induction, a manipulation of personal deservingness, or both. Results suggested that (a) LSEs feel less deserving of positive outcomes and of positive moods than do HSEs, (b) feelings of personal deservingness can vary with the situation, and be lowered through reminders of social rejection and personal flaws, and (c) feeling relatively undeserving dampens LSEs', but not HSEs', motivation to repair sad moods. These results have implications for the emotion regulation, self-esteem, and social justice literatures.

    A novel direct phase-selection method to select optimized phases from the ambiguous phases of a subset of reflections to replace the corresponding initial SAD phases has been developed. With the improved phases, the completeness of built residues of protein molecules is enhanced for efficient structure determination. Optimization of the initial phasing has been a decisive factor in the success of the subsequent electron-density modification, model building and structure determination of biological macromolecules using the single-wavelength anomalous dispersion (SAD) method. Two possible phase solutions (ϕ{sub 1} and ϕ{sub 2}) generated from two symmetric phase triangles in the Harker construction for the SAD method cause the well known phase ambiguity. A novel direct phase-selection method utilizing the θ{sub DS} list as a criterion to select optimized phases ϕ{sub am} from ϕ{sub 1} or ϕ{sub 2} of a subset of reflections with a high percentage of correct phases to replace the corresponding initial SAD phases ϕ{sub SAD} has been developed. Based on this work, reflections with an angle θ{sub DS} in the range 35–145° are selected for an optimized improvement, where θ{sub DS} is the angle between the initial phase ϕ{sub SAD} and a preliminary density-modification (DM) phase ϕ{sub DM}{sup NHL}. The results show that utilizing the additional direct phase-selection step prior to simple solvent flattening without phase combination using existing DM programs, such as RESOLVE or DM from CCP4, significantly improves the final phases in terms of increased correlation coefficients of electron-density maps and diminished mean phase errors. With the improved phases and density maps from the direct phase-selection method, the completeness of residues of protein molecules built with main chains and side chains is enhanced for efficient structure determination.

    Objective: To evaluate the clinical efficacy of greater omentum in reconstruction of refractory wounds. Methods: From August 1988 to May 2001, 20 patients with refractory wound underwent pedicle or microvascular free transfer of the greater omentum. Indications of surgery were electrical injury of the wrist and hand in 9 patients, electrical injury of the scalp and cranial bones in 3, avulsion injury of the scalp in 2, radiation-related ulcer of the chest wall in 2, ulcer and osteomyelitis following resection of the sternum sarcoma in 1, electrical injury of the abdomen in 1, bone and soft tissue defects following compound fracture of the leg in 1, and extensive scar and ulcer of the leg and footdrop following trauma in 1. Severe infection and extensive tissue necrosis were present prior to surgical operation in 12 patients. Eleven patients were treated with pedicled omental flaps, and 9 patients with free omental flaps. The size of the omental flaps ranged from 20 cm×12 cm to 38 cm×23 cm. Results: All the omental flaps survived. Healing at the first intention of the wounds was achieved in 17 cases. The on-top skin grafts resulted in partial necrosis of lipid liquefaction developed in the omentum and healed with dressing change in 2 cases. A sinus tract of osteomyelitis occurred in one case and healed after delayed excision of the necrosed bone. Follow-up study of all cases from 3 to 24 months showed no recurrent wounds and post-operative abdominal complication. Recovery with acceptable appearance and restoration of function was satisfactory. Conclusions: Greater omentum provides a well-vascularized tissue with lymphatic ducts for wound coverage. It has strong resistance against infection. It is very malleable and can be molded easily. Therefore it is an ideal tissue in filling cavities and repairing defects, especially in covering large and irregular defects that can not be treated with skin or muscle flaps.

    The condition of the sagebrush ecosystem has been declining in the Western United States, and greater sage-grouse (Centrocercus urophasianus), a sagebrush-obligate species, has experienced concurrent decreases in distribution and population numbers. This has prompted substantial research and management over the past two decades to improve the understanding of sage-grouse and its habitats and to address the observed decreases in distribution and population numbers. The amount of research and management has increased as the year 2015 approaches, which is when the U.S. Fish and Wildlife Service (FWS) is expected to make a final decision about whether or not to protect the species under the Endangered Species Act. In 2012, the Sage-Grouse Executive Oversight Committee (EOC) of the Western Association of Fish and Wildlife Agencies (WAFWA) requested that the U.S. Geological Survey (USGS) lead the development of a Greater Sage-Grouse National Research Strategy (hereafter Research Strategy). This request was motivated by a practical need to systematically connect existing research and conservation plans with persisting or emerging information needs. Managers and researchers also wanted to reduce redundancy and help focus limited funds on the highest priority research and management issues. The USGS undertook the development of this Research Strategy, which addresses information and science relating to the greater sage-grouse and its habitat across portions of 11 Western States. This Research Strategy provides an outline of important research topics to ensure that science information gaps are identified and documented in a comprehensive manner. Further, by identifying priority topics and critical information needed for planning, research, and resource management, it provides a structure to help coordinate members of an expansive research and management community in their efforts to conduct priority research.

    Hybridization of wildlife species, even in the absence of introgression, is of concern due to wasted reproductive effort and a reduction in productivity. In this study we detail an accidental mating between a female nyala (Tragelaphus angasii) and a male greater kudu (T. strepsiceros). The hybrid was phenotypically nyala and was identified as such based on mitochondrial DNA. Further genetic analysis based on nine microsatellite markers, chromosome number and chromosome morphology however, confirmed its status as an F1 hybrid. Results obtained from a reproductive potential assessment indicated that this animal does not have the potential to breed successfully and can be considered as sterile.

    The structure of a 14 kDa structural protein from Acidianus two-tailed virus (ATV) was solved by single-wavelength anomalous diffraction (SAD) phasing using X-ray data collected at 2.0 A wavelength. Although the anomalous signal from methionine sulfurs was expected to suffice to solve the structure......, one chloride ion turned out to be essential to achieve phasing. The minimal data requirements and the relative contributions of the Cl and S atoms to phasing are discussed. This work supports the feasibility of a systematic approach for the solution of protein crystal structures by SAD based...

    Patient satisfaction is increasingly being tied to reimbursement rates, and patient satisfaction is often associated with improving functionality and decreasing disability postoperatively. This study sought to determine if a total shoulder arthroplasty patient's preoperative confidence in his or her ability to attain the level of activity desired would influence postoperative functional scores. Patients undergoing a primary total shoulder arthroplasty at a single institution were asked to complete a preoperative questionnaire with multiple items including baseline symptom severity measures and their confidence in reaching their level of desired functionality postoperatively (scored 0-10). Patients then completed an identical postoperative questionnaire at their follow-up visits. Associations between the patient's confidence in attaining treatment goals and functional outcomes was established by multiple linear regression models that were adjusted for gender, age, body mass index, baseline 12-Item Short Form Health Survey mental component scores, college education, smoking status, baseline functional scores, and length of follow-up. Patients had a high level of confidence that their outcome would match their expectations, with an average score of 7.8 (range, 0-10; 28.4% reported a full 10/10 confidence). For every 1-point increase in confidence, patients experienced an average increase in their function score of 2.7 points (P = .039) and improvement in their pain score of 2.0 (P = .033) according to the Penn Shoulder Score. There was no significant association with the patient's 12-Item Short Form Health Survey score postoperatively. Patients with greater preoperative confidence actually have significantly better postoperative functional outcomes than their less confident peers even with adjustment for other known risk factors.

    Full Text Available Cities are ambiental, but also complex cultural tourist motifs. Different elements are combined in them, such as: attractiveness of architecture modern accomplishments, centers of cultural, artistic and sports life etc. Old city centers play an important role in cultural, tourist movements and they are unavoidable when visiting a city. They are complement ambiental motifs, extremely important as elements of attractiveness and complex motifs and therefore in the policy of tourist development they should be given special attention. Example tourist valorization of the old city center of Novi Sad has been conducted according to the Hillary du Cros model, i.e. the applicability of the market appeal/robusticity matrix on cultural tourism development has been estimated.

    2003-02-01

    SAD (single-wavelength anomalous diffraction) has enormous potential for phasing proteins using only the anomalous signal of the almost ubiquitous native sulfur, but requires extremely precise data. The previously unknown structure of the lima bean trypsin inhibitor (LBTI) was solved using highly redundant data collected to 3 A using a CCD detector with a rotating-anode generator and three-circle goniometer. The seven 'super-S' atoms (disulfide bridges) were located by dual-space recycling with SHELXD and the high solvent content enabled the density-modification program SHELXE to generate high-quality maps despite the modest resolution. Subsequently, a 2.05 A synchrotron data set was collected and used for further phase extension and structure refinement.

  10. The post-orgasmic prolactin increase following intercourse is greater than following masturbation and suggests greater satiety.

    2006-03-01

    Research indicates that prolactin increases following orgasm are involved in a feedback loop that serves to decrease arousal through inhibitory central dopaminergic and probably peripheral processes. The magnitude of post-orgasmic prolactin increase is thus a neurohormonal index of sexual satiety. Using data from three studies of men and women engaging in masturbation or penile-vaginal intercourse to orgasm in the laboratory, we report that for both sexes (adjusted for prolactin changes in a non-sexual control condition), the magnitude of prolactin increase following intercourse is 400% greater than that following masturbation. The results are interpreted as an indication of intercourse being more physiologically satisfying than masturbation, and discussed in light of prior research reporting greater physiological and psychological benefits associated with coitus than with any other sexual activities.

    Full Text Available Micro-cantilever sensors for mass detection using resonance frequency have attracted considerable attention over the last decade in the field of gas sensing. For such a sensing system, an oscillator circuit loop is conventionally used to actuate the micro-cantilever, and trace the frequency shifts. In this paper, gas experiments are introduced to investigate the mechanical resonance frequency shifts of the micro-cantilever within the circuit loop(mechanical resonance frequency, MRF and resonating frequency shifts of the electric signal in the oscillator circuit (system working frequency, SWF. A silicon beam with a piezoelectric zinc oxide layer is employed in the experiment, and a Self-Actuating-Detecting (SAD circuit loop is built to drive the micro-cantilever and to follow the frequency shifts. The differences between the two resonating frequencies and their shifts are discussed and analyzed, and a coefficientrelated to the two frequency shifts is confirmed.Micro-cantilever sensors for mass detection using resonance frequency have attracted considerable attention over the last decade in the field of gas sensing.

    In Western cultures it has often been assumed that the experience of happy or sad emotions while listening to music is clearly correlated to the key (mode) and the tempo of the musical piece. Recent studies point towards more complex dependencies, but knowledge in this line of research is still very limited, especially regarding the experience of music for persons with memory-related disorders such as dementia. This pilot study explores the emotional content of music for patients with mild cognitive impairment (MCI) and early-stage Alzheimer's disease (AD) and compares them to healthy subjects. A new test was specifically designed for this study and presented to 10 patients with MCI diagnosis, 10 with AD diagnosis and 23 controls. The test comprised musical stimuli consisting of chords and short musical pieces in major and minor mode with variable note density (number of notes per second). In the current study no significant correlation between key and the attribution of 'happy' or 'sad' judgements to a musical piece could be found in all groups. Note density, however, was shown to exhibit a strong influence on happy/sad judgements in all groups. Our findings indicate that the note density of a musical piece is much more important for happy/sad judgements than the key. Furthermore, the diagnosis MCI and early AD had no influence on the attribution of emotional expressions to musical pieces, corroborating recent findings of spared memory for music in these patient groups.

    Determination of protein crystal structures requires that the phases are derived independently of the observed measurement of diffraction intensities. Many techniques have been developed to obtain phases, including heavy-atom substitution, molecular replacement and substitution during protein expression of the amino acid methionine with selenomethionine. Although the use of selenium-containing methionine has transformed the experimental determination of phases it is not always possible, either because the variant protein cannot be produced or does not crystallize. Phasing of structures by measuring the anomalous diffraction from S atoms could in theory be almost universal since almost all proteins contain methionine or cysteine. Indeed, many structures have been solved by the so-called native sulfur single-wavelength anomalous diffraction (S-SAD) phasing method. However, the anomalous effect is weak at the wavelengths where data are normally recorded (between 1 and 2 Å) and this limits the potential of this method to well diffracting crystals. Longer wavelengths increase the strength of the anomalous signal but at the cost of increasing air absorption and scatter, which degrade the precision of the anomalous measurement, consequently hindering phase determination. A new instrument, the long-wavelength beamline I23 at Diamond Light Source, was designed to work at significantly longer wavelengths compared with standard synchrotron beamlines in order to open up the native S-SAD method to projects of increasing complexity. Here, the first novel structure, that of the oxidase domain involved in the production of the natural product patellamide, solved on this beamline is reported using data collected to a resolution of 3.15 Å at a wavelength of 3.1 Å. The oxidase is an example of a protein that does not crystallize as the selenium variant and for which no suitable homology model for molecular replacement was available.

  18. Modeling the two-locus architecture of divergent pollinator adaptation: how variation in SAD paralogs affects fitness and evolutionary divergence in sexually deceptive orchids

    Divergent selection by pollinators can bring about strong reproductive isolation via changes at few genes of large effect. This has recently been demonstrated in sexually deceptive orchids, where studies (1) quantified the strength of reproductive isolation in the field; (2) identified genes that appear to be causal for reproductive isolation; and (3) demonstrated selection by analysis of natural variation in gene sequence and expression. In a group of closely related Ophrys orchids, specific floral scent components, namely n-alkenes, are the key floral traits that control specific pollinator attraction by chemical mimicry of insect sex pheromones. The genetic basis of species-specific differences in alkene production mainly lies in two biosynthetic genes encoding stearoyl–acyl carrier protein desaturases (SAD) that are associated with floral scent variation and reproductive isolation between closely related species, and evolve under pollinator-mediated selection. However, the implications of this genetic architecture of key floral traits on the evolutionary processes of pollinator adaptation and speciation in this plant group remain unclear. Here, we expand on these recent findings to model scenarios of adaptive evolutionary change at SAD2 and SAD5, their effects on plant fitness (i.e., offspring number), and the dynamics of speciation. Our model suggests that the two-locus architecture of reproductive isolation allows for rapid sympatric speciation by pollinator shift; however, the likelihood of such pollinator-mediated speciation is asymmetric between the two orchid species O. sphegodes and O. exaltata due to different fitness effects of their predominant SAD2 and SAD5 alleles. Our study not only provides insight into pollinator adaptation and speciation mechanisms of sexually deceptive orchids but also demonstrates the power of applying a modeling approach to the study of pollinator-driven ecological speciation.

    This study examines the action research topics and topic preferences of two groups of grassroots teachers: active researchers, and potential researchers. The analysis of the topics appears to indicate that, over the past decade, action research at the teaching of English at the grassroots level to speakers of other languages has been principally understood in terms of professional development with respect to teachers’ methodologies and learners’ learning behaviours. A nascent concern for a more ample approach to professional development and issues conducive to the greater good of the profession can, it is mooted, flourish only with the collaboration of all relevant stakeholders.

    En este estudio se examinan los temas de investigación acción y los temas preferidos por dos grupos de profesores de base: uno de investigadores activos y otro de investigadores potenciales. El análisis sugiere que, durante la última década, la investigación acción en el aula de inglés para hablantes de otras lenguas se ha entendido principalmente en términos del desarrollo profesional con respecto a las metodologías de los profesores y las conductas estudiantiles de aprendizaje. Se considera que un incipiente interés por un enfoque más amplio y por asuntos conducentes al beneficio general de la profesión, solamente puede florecer con la colaboración de todos los actores más importantes.

With no statutory governance currently in place, it is concerned that a rash of badly-designed, poorer quality variants, that it says have emerged in recent years, pose a significant self-harm and ligature risk to mentally unwell patients in hospitals, and a potential danger to staff when components like internal fittings and the glass itself, especially should the latter be too thin and thus easy to break, are used as "weapons".

    Full Text Available Introduction. Salt intake above 5 g/person/day is a strong independent risk factor for hypertension, stroke and cardiovascular diseases. Published studies indicate that the main source of salt in human diet is processed ready-to-eat food, contributing with 65-85% to daily salt intake. Objective. The aim of this paper was to present data on salt content of ready-to-eat food retailed in Novi Sad, Serbia, and contribution of the salt contained in 100 g of food to the recommended daily intake of salt for healthy and persons with cardiovascular disease (CVD risk. Methods. In 1,069 samples of ready-to-eat food, salt (sodium chloride content was calculated based on chloride ion determined by titrimetric method, while in 54 samples of bottled water sodium content was determined using flame-photometry. Food items in each food group were categorized as low, medium or high salt. Average salt content of each food group was expressed as a percentage of recommended daily intake for healthy and for persons with CVD risk. Results. Average salt content (g/100 g ranged from 0.36±0.48 (breakfast cereals to 2.32±1.02 (grilled meat. The vast majority of the samples of sandwiches (91.7%, pizza (80.7%, salami (73.9%, sausages (72.9%, grilled meat (70.0% and hard cheese (69.6% had a high salt profile. Average amount of salt contained in 100 g of food participated with levels ranging from 7.2% (breakfast cereals to 46.4% (grilled meat and from 9.6% to 61.8% in the recommended daily intake for healthy adult and person with CVD risk, respectively. Average sodium content in 100 ml of bottled spring and mineral water was 0.33±0.30 mg and 33±44 mg, respectively. Conclusion. Ready-to-eat food retailed in Novi Sad has high hidden salt content, which could be considered as an important contributor to relatively high salt consumption of its inhabitants.

    Bullying is a common exposure in high school and more recently cyberbullying has become prevalent among teens. We used the 2011 Arkansas Youth Risk Behavior Survey to estimate the prevalence of school bullying and cyberbullying and to measure its association with teen suicidality. In Arkansas, 11.6% of students reported only school bullying, 6.2% only cyberbullying, and 10.2% both forms of bullying. We determined "feeling unsafe at school" was a significant risk factor for depression and all suicide questions. We also found that being a victim of school bullying, cyberbullying, or both, increased the risk for depression, suicidal ideation, and plan.

    1988-04-01

    The Princeton Beta Experiment-Modification (PBX-M) is an experimental device of the tokamak type. A tokamak is characterized by a strong toroidal magnetic field composed of an externally driven component parallel to the torus centerline modified by the field produced by a transformer-driven current (OH) in the confined plasma. A second magnetic field parallel to the major toroidal axis is added to provide radial equilibrium for the plasma. As an advanced tokamak, PBX-M will have additional magnetic fields to reshape the plasma cross section from a circle into a kidney bean shape; it will also be equipped with 6MW or more of auxiliary heating power provided by four neutral beam injectors, with RF systems, and with an extensive set of diagnostics. Potential hazards associated with PBX-M, which are analyzed in this report, result from energy stored in the magnetic fields, high voltages necessary for the operation of some of the equipment and diagnostics, neutron radiation when the neutral beams are run with deuterium and x-rays, especially those emitted as a result of plasma-wall interaction. This report satisfies the requirements set forth in the PPPL Health and Safety Directives, specifically HSD-5003, and in DOE Order 5481.1B and its Chicago operations supplement (DOE86, DOE82).

    Full Text Available Field experience has been considered a vital part of teacher education. Universities have to search for ways for student teachers to gain experience in an authentic teaching environment. Several successful models incorporating service learning have been reported across fields (Brooks & Schramm, 2007; Nandan, 2010; Salas, Safaradan, & Ugarte, 2008, but there is still insufficient research found that combined English teacher preparation and service learning (Hsieh, 2002. Consequently, this researcher incorporated service learning into an English methodology course in Taiwan to engage students in higher learning experiences that take them beyond traditional teacher training. This paper describes a four-stage process of community service teaching, presenting its benefits and challenges. This study which incorporated quantitative and qualitative methodologies proved that teaching practices in collaboration with community libraries created three-way benefits: advancing the quality of college education and bringing valuable learning opportunities to the student teachers as well as the children who participated; and creating memorable experiences for the students and the communities that participated. Keywords: service learning, teacher preparation, university partnership, higher education

    Little is known of the possible relationship between a diagnosis of attention-deficit/hyperactivity disorder (ADHD) and sexually offensive behavior in adolescents. Our aim was to understand how adolescents with ADHD who had sexually offended described their childhood experiences and spoke about their diagnostic symptoms. The boys' early lives and relations were unpredictable, and emotional, physical, and sexual limits had been crossed. However, many boys saw themselves or their diagnosis, rather than their parents, school, or "society," as the underlying cause of their behavior. They used different strategies, for example repressing memories or regarding traumatic experiences as normal, to manage their lives. Most boys had difficulty with emotions and expressed sadness or frustration through anger. They spoke of being inattentive and restless in school and impulsive before and during their sexual offenses. The psychiatric assessment was described as a "messy" experience that strengthened their belief that something was wrong with them. Some had incorporated neuropsychiatric language into otherwise limited vocabularies and tended to use their diagnostic symptoms to excuse their offenses. The focus in the assessment on the boys themselves and their behaviors may darken their understandings of themselves, their experiences of abuse, and the offenses they have committed. Further research is needed into the possible consequences of a diagnosis of ADHD on adolescents' self-image and sense of self-control.

    A large number of Z-DNA hexamer duplex structures and a few oligomers of different lengths are available, but here the first crystal structure of the d(CGCGCGCGCGCG)2 dodecameric duplex is presented. Two synchrotron data sets were collected; one was used to solve the structure by the single-wavelength anomalous dispersion (SAD) approach based on the anomalous signal of P atoms, the other set, extending to an ultrahigh resolution of 0.75 Å, served to refine the atomic model to an R factor of 12.2% and an R(free) of 13.4%. The structure consists of parallel duplexes arranged into practically infinitely long helices packed in a hexagonal fashion, analogous to all other known structures of Z-DNA oligomers. However, the dodecamer molecule shows a high level of flexibility, especially of the backbone phosphate groups, with six out of 11 phosphates modeled in double orientations corresponding to the two previously observed Z-DNA conformations: Z(I), with the phosphate groups inclined towards the inside of the helix, and Z(II), with the phosphate groups rotated towards the outside of the helix.

  11. Binocular Symmetry/Asymmetry of Scleral Redness as a Cue for Sadness, Healthiness, and Attractiveness in Humans

    Full Text Available Among primates, only humans have the white sclerae that provide the ground necessary to display their own color and that of the overlying conjunctiva. Scleral color, primarily redness, provides cues of socially and biologically significant information about an individual. The present study examines the effect of the asymmetry of binocular scleral redness on perceived sadness, healthiness, and attractiveness by contrasting ratings of images of individuals who had one, both, or neither sclera reddened by digital editing. Building upon previous research, this study further defines the details of the scleral color display and contributes to the more general issue of facial and body symmetry, predictors of phenotypic condition and genotypic quality that are of interest to evolutionary theorists. Individuals with binocular and monocular redness were rated as sadder, less healthy, and less attractive than those with untinted control sclerae, with ratings corresponding to the degree of redness or whiteness. Bilaterally symmetrical (binocular scleral redness or whiteness provided anchorage points for ratings, with ratings for bilaterally asymmetrical (monocular redness or whiteness falling between them; there was no unique effect of asymmetry.

It is necessary to enhance detection and control for SAdV in monkeys and relevant biological products, and avoid potential risk of human infection.

  13. Anger, Sadness and Fear in Response to Breaking Crime and Accident News Stories: How Emotions Influence Support for Alcohol-Control Public Policies via Concern about Risks.

    2013-01-01

    Prior research shows that discrete emotions, notably anger and fear, can explain effects of news articles on health and alcohol-control policy support. This study advances prior work by coding expressed emotional responses to messages (as opposed to directly manipulated emotions or forced responses), incorporating and controlling for central thoughts, including sadness (a particularly relevant response to tragic stories), and examining concern's mediating role between emotion and policy support. An experiment with a national online adult panel had participants read one of 60 violent crime or accident news stories, each manipulated to mention or withhold alcohol's causal contribution. Multi-group structural equation models suggest that stories not mentioning alcohol had a direct effect on policy support via fear and central thoughts, unmediated by concern. When alcohol was mentioned, sadness and anger affects alcohol-control support through concern. Findings help confirm that emotional responses are key in determining news story effects on public support of health policies.

    The aim of the present study is the investigation of the potential role of negative relating to others, perceived loneliness, sadness, and anxiety, as mediators of the association between early parental bonding and adult Internet Addiction (IA). The factorial structure of the Internet Addiction Test (IAT) and the prevalence rates of it in a Greek sample will also be investigated. A total of 774 participants were recruited from a Technological Education Institute (mean age=20.2, SD=2.8) and from high school technical schools (mean age=19.9, SD=7.4). The IAT was used to measure the degree of problematic Internet use behaviors; the Parental Bonding Instrument was used to assess one's recalled parenting experiences during the first 16years of life; the shortened Person's Relating to Others Questionnaire was used to assess one's negative (i.e. maladaptive) relating to others (NRO). Both exploratory and confirmatory factor analyses confirmed the three-factor structure of the IAT. Only 1.0% of the sample was severely addicted to the Internet. The mediated effects of only the NRO and sadness were confirmed. Negative relating to others was found to fully mediate the effect of both the father's optimal parenting and affectionless control on IA, whereas sadness was found to fully mediate the effect of the mother's optimal parenting on IA. Overall, the results suggest that parenting style has an indirect impact on IA, through the mediating role of negative relating to others or sadness in later life. Both family-based and individual-based prevention and intervention efforts may reduce the incidence of IA.

    Full Text Available Backround/Aim. From 1984 to 2004 the city of Novi Sad participated through its Health Center “Novi Sad” in the international Multinational MONItoring of Trends and Determinants in CArdiovascular Disease (MONICA project, as one of the 38 research centers in 21 countries around the world. The aim of this study was to determine frequency and changes of trends in leading risk factors of coronary heart disease (CHD and to analyze the previous trend of movement of coronary event in women in Novi Sad during a 20- year period. Methods. In 2004, the fourth survey within MONICA project was conducted in the city of Novi Sad. The representative sample included 1,041 women between the age of 25 and 74. The prevalence of risk factors in CHD such as smoking, high blood pressure, elevated blood cholesterol, elevated blood glucose and obesity was determined. Also, indicators of risk factors and rates of coronary events in women were compared with the results from MONICA project obtained in previous three screens, as well as with the results from other research centres. χ2-test, linear trend and correlartion coefficient were used in statistical analysis of results obtained. Results. It was observed that during a 20-year period covered by the study, the prevalence of the leading risk factors for the development of CHD in the surveyed women was significantly increasing and in positive correlation with the values of linear trend. Also, the increase of morbidity rates and mortality rates of coronary event were in positive correlation. The decrease was only recorded in the period from 1985-1989 (the implementation of the intervention programme. Conclusion. Upon analysing the increase in prevalence of leading risk factors of CHD and significant increase in the rates of coronary event, we can conclude that health status of women in Novi Sad during a 20-year period was deteriorating.

    Much is known about development of the ability to label facial expressions of emotion (e.g., as happy or sad), but rather less is known about the emergence of more complex emotional face processing skills. The present study investigates one such advanced skill: the ability to tell if someone is genuinely feeling an emotion or just pretending (i.e., authenticity discrimination). Previous studies have shown that children can discriminate authenticity of happy faces, using expression intensity as an important cue, but have not tested the negative emotions of sadness or fear. Here, children aged 8-12 years (n = 85) and adults (n = 57) viewed pairs of faces in which one face showed a genuinely-felt emotional expression (happy, sad, or scared) and the other face showed a pretend version. For happy faces, children discriminated authenticity above chance, although they performed more poorly than adults. For sad faces, for which our pretend and genuine images were equal in intensity, adults could discriminate authenticity, but children could not. Neither age group could discriminate authenticity of the fear faces. Results also showed that children judged authenticity based on intensity information alone for all three expressions tested, while adults used a combination of intensity and other factor/s. In addition, novel results show that individual differences in empathy (both cognitive and affective) correlated with authenticity discrimination for happy faces in adults, but not children. Overall, our results indicate late maturity of skills needed to accurately determine the authenticity of emotions from facial information alone, and raise questions about how this might affect social interactions in late childhood and the teenage years.

    Full Text Available Because of its geopolitical and tourist location and because of its ethnic composition, Novi Sad is known as one cosmopolitan city that grew to become the place of gathering and dialogue of many nations, cultures and religious communities. No matter if they are believers, agnostics, atheists, pilgrims, city tourists, travelling through or are the inhabitants, young, middle-aged or retired, all beneficent people can find here all the necessary information written on the account of rich religious and historical sources. The subject of this paper is the tourist valorization of the eight most attractive Roman-Catholic sacred objects in Novi Sad, Petrovaradin and Sremska Kamenica. In this paper the analyzed cultural and religious assets represent alternatives while indicators of the quantitative-qualitative method of assessment of cultural sites are used as criteria. And AHP gradually compares alternatives according to chosen criterion and measures their impact on the goal, which helps man to make the right decision. From the results of the assessment of the analyzed sacred objects The Name of Mary Church with Catholic churchyard and Vicarage – Novi Sad is ranked as the most attractive site. Then, in second place is the Franciscan converts St. George the Martyr – Petrovaradin, followed by The Church of Snežna Gospa in Tekije – Petrovaradin.

  1. Greater Happiness for a Greater Number: Did the Promise of Enlightenment Come True?

    In the eighteenth century 'Enlightened' thinkers challenged the belief that happiness exists only in Heaven. They claimed that happiness is possible in earthly life and foresaw that greater happiness would be achieved using reason. Did this promise of greater happiness come true? Several scholars doubt that we have become any happier and some claim that happiness has declined. These critical claims are tested using the time trend data available in the World Database of Happiness, which cover the period 1950-2010 and involve 1531 data points in 67 nations yielding 199 time-series ranging for 10 to more than 40 years. The analysis reveals that happiness has risen in most nations. The average yearly rise in the 67 nations was +0.012 on scale 0-10, which equals a rise of one full point every 83 years. At this rate happiness must have improved by more than two points over the past two centuries and, together with increasing longevity, this denotes an unprecedented rise in happy life years.

    The contents of 16 organochlorine pesticides (OCPs) and six so-called indicator polychlorinated biphenyls (PCBs) were determined in the surface zone (0-5 cm) of soil and sediment samples, taken from different locations in the city of Novi Sad, capitol of Vojvodina Province (North of the Serbia) covering residential and commercial area, recreational and arable zone. The total organochlorine pesticides concentration in soil varied from 2.63 to 31.78 ng g(-1) dry weight, while the level in sediment was 10.35 ng g(-1) dry weight. Maximum content of identified individual organochlorine pesticide in soil samples was 10.40 ng g(-1) dry weight for p, p-DDE in the market garden and 6.31 ng g(-1) dry weight for p, p'-DDT in sediment of the Danube River, although their application is restricted in Serbia. Some of investigated PCBs were identified only in the soil samples from a park-school backyard in the city downtown (0.32 ng g(-1) dry weight) and market garden (0.22 ng g(-1) dry weight), and also in sediment sample from left bank of the Danube River (0.41 ng g(-1) dry weight). Data of the OCPs and PCBs present in this study were compared with the ones found for soils and river sediments throughout the world, and with limit values set by soil and sediment quality guidelines. Also, correlation between the levels of certain pesticides and soil characteristics (organic matter, pH and clay content) was investigated.

    According to dominant neuropsychological theories of affect, emotions signal salience of events and in turn facilitate a wide spectrum of response options or action tendencies. Valence of an emotional experience is pivotal here, as it alters reward and punishment processing, as well as the balance between safety and risk taking, which can be translated into changes in the exploration-exploitation trade-off during reinforcement learning (RL). To test this idea, we compared the behavioral performance of three groups of participants that all completed a variant of a standard probabilistic learning task, but who differed regarding which mood state was actually induced and maintained (happy, sad or neutral). To foster a change from an exploration to an exploitation-based mode, we removed feedback information once learning was reliably established. Although changes in mood were successful, learning performance was balanced between the three groups. Critically, when focusing on exploitation-driven learning only, they did not differ either. Moreover, mood valence did not alter the learning rate or exploration per se, when titrated using complementing computational modeling. By comparing systematically these results to our previous study (Bakic et al., 2014), we found that arousal levels did differ between studies, which might account for limited modulatory effects of (positive) mood on RL in the present case. These results challenge the assumption that mood valence alone is enough to create strong shifts in the way exploitation or exploration is eventually carried out during (probabilistic) learning. In this context, we discuss the possibility that both valence and arousal are actually necessary components of the emotional mood state to yield changes in the use and exploration of incentives cues during RL.

    Full Text Available Background. Evidence suggests that insufficient sleep duration is associated with an increased likelihood for hypertension. Both short (8 hour sleep durations as well as hypertension are more prevalent among blacks than among whites. This study examined associations between sleep duration and hypertension, considering differential effects of race and ethnicity among black and white Americans. Methods. Data came from a cross-sectional household interview with 25,352 Americans (age range: 18–85 years. Results. Both white and black short sleepers had a greater likelihood of reporting hypertension than those who reported sleeping 6 to 8 hours. Unadjusted logistic regression analysis exploring the race/ethnicity interactions between insufficient sleep and hypertension indicated that black short (8 hours sleepers were more likely to report hypertension than their white counterparts (OR = 1.34 and 1.37, resp.; P<0.01. Significant interactions of insufficient sleep with race/ethnicity were observed even after adjusting to effects of age, sex, income, education, body mass index, alcohol use, smoking, emotional distress, diabetes, coronary heart disease, and stroke. Conclusion. Results suggest that the race/ethnicity interaction is a significant mediator in the relationship between insufficient sleep and likelihood of having a diagnosis of hypertension.

    Full Text Available Policy-making that re-presents – as objects of concern and by means of statistics – the suffering or depression and the happiness of populations indicates an evolving form of governance that examines and reshapes subjectivity itself. Never before have states of subjectivity been acted upon, through surveys, statistical and policy analysis, and scientific disciplines, to the extent seen today. This article: Documents changing epistemic co-ordinates, especially in psychology and economics, that first occluded happiness in the interests of objectivity, but, in recent decades, marked out a renewed ‘science’ of happiness.Examines changes in the discursive formulation of depression, as a counterpart to happiness.Argues that, seen in terms of bio-power, contemporary concerns for happiness and depression are consistent – rather than incompatible – with one another. How can so many claim to be happy when so many, we are told, are depressed, anxious or suffering emotional pain? There is no underlying contradiction here, for two reasons: Happiness and depression are manifestations of the same political discourse (or aspects of a political subjectivity characterized by dis-inhibition, consumer self-indulgence and performance anxiety. And, just as we needed madness in order to understand ‘sanity,’ or the prison in order to view ourselves as ‘free,’ so we rely upon concerns about depression in order to understand and act upon ourselves as subjects capable of unlimited happiness.

    Among vertebrates hippocampus forms the major component of the brain in consolidating information from short-term memory to long-term memory. Aging is considered as the major risk factor for memory impairment in sporadic Alzheimer's disease (SAD) like pathology. Present study thus aims at investigating whether age-specific degeneration of neuronal-circuits in hippocampal formation (neural-layout of Subiculum-hippocampus proper-dentate gyrus (DG)-entorhinal cortex (EC)) results in cognitive impairment. Furthermore, the neuroprotective effect of Resveratrol (RSV) was attempted to study in the formation of hippocampal neuronal-circuits. Radial-Arm-Maze was conducted to evaluate hippocampal-dependent spatial and learning memory in control and experimental rats. Nissl staining of frontal cortex (FC), subiculum, hippocampal-proper (CA1→CA2→CA3→CA4), DG, amygdala, cerebellum, thalamus, hypothalamus, layers of temporal and parietal lobe of the neocortex were examined for pathological changes in young and aged wistar rats, with and without RSV. Hippocampal trisynaptic circuit (EC layerII→DG→CA3→CA1) forming new memory and monosynaptic circuit (EC→CA1) that strengthen old memories were found disturbed in aged rats. Loss of Granular neuron observed in DG and polymorphic cells of CA4 can lead to decreased mossy fibers disturbing neural-transmission (CA4→CA3) in perforant pathway. Further, intensity of nissl granules (stratum lacunosum moleculare (SLM)-SR-SO) of CA3 pyramidal neurons was decreased, disturbing the communication in schaffer collaterals (CA3-CA1) during aging. We also noticed disarranged neuronal cell layer in Subiculum (presubiculum (PrS)-parasubiculum (PaS)), interfering output from hippocampus to prefrontal cortex (PFC), EC, hypothalamus, and amygdala that may result in interruption of thought processes. We conclude from our observations that poor memory performance of aged rats as evidenced through radial arm maze (RAM) analysis was due to the

    Myiasis is the infestation of tissues of live vertebrate animals and humans with dipterous larvae. In sub-Saharan Africa, Cordylobia anthropohaga and Cordylobia rodhaini are known to be responsible for cutaneous myiasis in animals and humans. Human cases of myiasis, purportedly acquired in Ghana but diagnosed in other countries, have been reported; however, published data on its occurrence in animals in Ghana is unavailable. This study assessed the prevalence of canine myiasis among owned dogs in the Greater Accra region (GAR) of Ghana. A cross-sectional study was conducted in the Greater Accra region of Ghana, selected for being the region with the highest estimated population density of owned dogs. Physical examination and demographic characteristics of the study dogs were assessed. Management of the dogs was assessed through a questionnaire administered to the dog owners. A total of 392 owned dogs were sampled. Twenty-nine (7.4%) had cutaneous myiasis caused by C. rodhaini. In addition, one (0.2%) of the dogs had intestinal myiasis, with Dermatobia hominis as the offending larvae. Among the breeds of dogs with myiasis, the mongrel was most affected, with 24 (82.8%) out of the 29 cases. The mongrels, majority of which (24; 82.8%) were males, were left to roam freely in the community. Results from this study demonstrate that C. rodhaini and D. hominis are important causes of myiasis in owned dogs in the GAR of Ghana. Dogs could play a role in the spread of myiasis to humans, with its attendant public health implications.

    Reticuloendotheliosis (RE) in captive greater prairie chickens (GPC, Tympanuchus cupido pinnatus) and Attwater's prairie chickens (APC, Tympanuchus cupido attwateri) was first reported in 1998. RE is caused by avian reticuloendotheliosis virus (REV), an oncogenic and immunosuppressive retrovirus infecting multiple species of wild and domestic birds. During August 2004 through May 2006 a captive population of prairie chickens was affected simultaneously with a neoplastic condition and also avian pox, the latter being detected in 7.4% (2 of 27) of all birds submitted for histopathology. A survey for REV was conducted in order to examine its possible role in mortality observed primarily in juvenile and adult specimens of prairie chickens. The investigative procedures included postmortem examinations, histopathology, molecular detection, and virus isolation. In total, 57 Attwater's prairie chickens and two greater prairie chickens were included in the study. REV infection was diagnosed using virus isolation or polymerase chain reaction (PCR) or both in 59.5% (28 of 47) of blood samples and/or tumors from suspect birds. Lymphosarcomas were detected in the tissues of 37% (10 of 27) of the birds submitted for histopathology. Such lymphosarcomas suggestive of RE represented the most frequent morphologic diagnosis on histopathology among 27 separate submissions of naturally dead prairie chickens. Overall, REV was detected or RE diagnosed in 34 of 59 prairie chickens (57.62%). The average death age of all birds diagnosed with lymphosarcomas on histopathology was 2.2 yr, ranging from birds of undetermined gender). Reticuloendotheliosis virus was confirmed as a significant cause of mortality in captive prairie chickens.

    Objectives: Social anxiety disorder (SAD) is a common and debilitating anxiety disorders. However, few studies had been dedicated to the neurobiology underlying SAD until the last decade. Rates of non-responders to standard methods of treatment remain unsatisfactorily high of approximately 25%, including SAD. Advances in our understanding of SAD could lead to new treatment strategies. A potential non invasive therapeutic option is repetitive transcranial magnetic stimulation (rTMS). Thus, we reported two cases of SAD treated with rTMS Methods: The bibliographical search used Pubmed/Medline, ISI Web of Knowledge and Scielo databases. The terms chosen for the search were: anxiety disorders, neuroimaging, repetitive transcranial magnetic stimulation. Results: In most of the studies conducted on anxiety disorders, except SAD, the right prefrontal cortex (PFC), more specifically dorsolateral PFC was stimulated, with marked results when applying high-rTMS compared with studies stimulating the opposite side. However, according to the “valence hypothesis”, anxiety disorders might be characterized by an interhemispheric imbalance associated with increased right-hemispheric activity. With regard to the two cases treated with rTMS, we found a decrease in BDI, BAI and LSAS scores from baseline to follow-up. Conclusion: We hypothesize that the application of low-rTMS over the right medial PFC (mPFC; the main structure involved in SAD circuitry) combined with high-rTMS over the left mPFC, for at least 4 weeks on consecutive weekdays, may induce a balance in brain activity, opening an attractive therapeutic option for the treatment of SAD.

    A prototype rotating hybrid magnetic resonance imaging system and linac has been developed to allow for simultaneous imaging and radiation delivery parallel to B 0. However, the design of a compact magnet capable of rotation in a small vault with sufficient patient access and a typical clinical source-to-axis distance (SAD) is challenging. This work presents a novel superconducting magnet design as a proof of concept that allows for a reduced SAD and ample patient access by moving the superconducting coils to the side of the yoke. The yoke and pole-plate structures are shaped to direct the magnetic flux appropriately. The outer surface of the pole plate is optimized subject to the minimization of a cost function, which evaluates the uniformity of the magnetic field over an ellipsoid. The magnetic field calculations required in this work are performed with the 3D finite element method software package Opera-3D. Each tentative design strategy is virtually modeled in this software package, which is externally controlled by MATLAB, with its key geometries defined as variables. The optimization variables are the thickness of the pole plate at control points distributed over the pole plate surface. A novel design concept as a superconducting non-axial magnet is introduced, which could create a large uniform B 0 magnetic field with fewer geometric restriction. This non-axial 0.5 T superconducting magnet has a moderately reduced SAD of 123 cm and a vertical patient opening of 68 cm. This work is presented as a proof of principle to investigate the feasibility of a non-axial magnet with the coils located around the yoke, and the results encourage future design optimizations to maximize the benefits of this non-axial design.

    We examined whether anger-in, anger-out, and hostility predicted symptom-specific muscle tension reactivity during anger induction (but not sadness induction) among patients with chronic low back pain (CLBP). For patients with CLBP, relevant muscles are the lower paraspinals (LPs). Anger-in x hostility and anger-out x hostility interactions were tested to determine whether particularly reactive groups of patients could be identified with a multivariable profile approach. Ninety-four patients with CLBP underwent anger recall (ARI) and sadness recall (SRI) interviews, whereas LP and trapezius electromyography and systolic blood pressure, diastolic blood pressure, and heart rate were recorded. They completed anger-in, anger-out, hostility, and trait anger measures. Hierarchical regressions were used to test anger-in x hostility and anger-out x hostility interactions for physiological changes during the ARI and SRI. A significant anger-in x hostility interaction was found for LP change during the ARI (but not SRI) such that high anger-in/high hostility patients evinced the greatest reactivity. Effects for trapezius reactivity were nonsignificant. Significant anger-in x hostility interactions were also found for systolic blood pressure and diastolic blood pressure changes during the ARI such that high anger-in/low hostility patients showed the smallest changes. The anger-out x hostility interaction for diastolic blood pressure change during ARI was also significant such that high anger-out/low hostility patients showed the smallest changes. All effects remained significant with trait anger controlled. A multivariable profile approach may help identify especially vulnerable patient groups. Patients with CLBP who tend to suppress anger and are cynically hostile may be more likely to experience high levels of muscle tension near the site of pain and injury during anger, but not during sadness, than other groups.

    Full Text Available In this study we used event-related brain potentials (ERP as neural markers of cognitive operations to examine emotion and attentional processing in a population of high-risk adolescents with mental health problems that included ADHD, anxiety, and depression. We included a healthy control group for comparison purposes, and employed a modified version of the emotional oddball paradigm, consisting of frequent distracters (scrambled pictures, infrequent distracters (sad, fearful, and neutral pictures and infrequent targets (circles. Participants were instructed to make a right hand button press to targets and a left hand button press to all other stimuli. EEG/ERP recordings were taken using a high-density 256-channel recording system. Behavioral data showed that for both clinical and non-clinical adolescents, reaction time was slowest in response to the fearful images. Electrophysiological data differentiated emotion and target processing between clinical and non-clinical adolescents. In the clinical group we observed a larger P100 and Late Positive Potential (LPP in response to fearful compared to sad or neutral pictures. There were no differences in these ERPs in the healthy sample. Emotional modulation of target processing was also identified in the clinical sample, where we observed an increase in P300 amplitude, and a larger sustained LPP in response to targets that followed emotional pictures (fear & sad compared to targets that followed neutral pictures or other targets. There were no differences in these target ERPs for the healthy participants. Taken together, we suggest that these data provide important and novel evidence of affective and attention dysfunction in this clinical population of adolescents, and offer an example of the disruptive effects of emotional reactivity on basic cognition.

    The identification of predictors for body image distortion would be an especially important first step in targeting a vulnerable population and developing a nutrition intervention program. We aimed to investigate the prevalence of body image distortion and the factors associated with body image distortion among Korean high school students. We selected 20,264 normal weight high school students from the 10(th) Korea Youth Risk Behavior Web-based Survey using nationally representative data in 2014. With multivariate logistic regression, we assessed the association of body image distortion with individual demographic and socio-economic factors, weight control behaviors, and mental health characteristics. The over-estimation group of body weight status, compared with the correct estimation group, was significantly more likely to be a 3(rd) year high school student [adjusted odds ratio (AOR): 1.27, 95% confidence interval (CI): 1.16-1.39], to be female [AOR: 3.52, 95% CI: 3.25-3.81], to employ unhealthy weight control behaviors [AOR: 1.54, 95% CI: 1.37-1.72], and to have a sadness [AOR: 1.25, 95% CI: 1.16-1.35] and suicidal ideation [AOR: 1.20, 95% CI: 1.08-1.33]. The under-estimation group, compared with the correct estimation group, was significantly less likely to be female [AOR: 0.23, 95% CI: 0.21-0.25] and to employ unhealthy weight control behaviors [AOR: 0.50, 95% CI: 0.43-0.59] but were more likely to have a sadness [AOR: 1.12, 95% CI: 1.03-1.21] and suicidal ideation [AOR: 1.12, 95% CI: 1.00-1.25]. Not only the over-estimation but also the under-estimation of body weight is prevalent among high school students in South Korea. Body image distortion was significantly associated with sadness and suicidal ideation.

    Mulligan, Edward P; Middleton, Emily F; Brunette, Meredith

    2015-08-01

    Greater trochanteric pain syndrome is an enigmatic but common cause of lateral hip symptoms in middle-aged active women. The most common manifestation of this syndrome is a degenerative tendinopathy of the hip abductors similar to the intrinsic changes seen with rotator cuff pathology in the shoulder. There are no definitive tests to isolate the underlying pathology and palpation is a non-specific means by which to differentiate the source of the pain generator. The physical examination must comprehensively evaluate for a cluster of potential impairments and contributing factors that will need to be addressed to effectively manage the likely functional limitations and activity challenges the syndrome presents to the patient. Compressive forces through increased tension in the iliotibial band should be avoided. Intervention strategies should include education regarding postural avoidance, activity modifications, improvement of lumbopelvic control, and a patient approach to resolving hip joint restrictions and restoring the tensile capabilities of the deep rotators and abductors of the hip. A number of reliable and validated hip-specific self-report outcome tools are available to baseline a patient's status and monitor their progress. Further investigations to identify the epidemiological risk factors, establish effective treatment strategies, and predict prognosis are warranted.

    Directory of Open Access Journals (Sweden)

    2013-09-01

    Full Text Available SADS is defined as sudden death under the age of 40 years old in the absence of structural heart disease. Family screening studies are able to identify a cause in up to 50% of cases-most commonly long QT syndrome, Brugada and early repolarisation syndrome, and catecholaminergic polymorphic ventricular tachycardia using standard clinical screening investigations including pharmacological challenge testing. These diagnoses may be supported by genetic testing which can aid cascade screening and may help guide management. In the current era it is possible to undertake molecular autopsy provided suitable samples of DNA can be obtained from the proband. With the evolution of rapid sequencing techniques it is possible to sequence the whole exome for candidate genes. This major advance offers the opportunity to identify novel causes of lethal arrhythmia but also poses the challenge of managing the volume of data generated and evaluating variants of unknown significance. The emergence of induced pluripotent stem cell technology could enable evaluation of the electrophysiological relevance of specific ion channel mutations in the proband or their relatives and will potentially enable screening of idiopathic ventricular fibrillation survivors combining genetic and electrophysiological studies in derived myocytes. This also could facilitate the assessment of personalised preventative pharmacological therapies. This review will evaluate the current screening strategies in SADS families, the role of molecular autopsy and genetic testing and the potential applications of molecular and cellular diagnostic strategies on the horizon.

    2008-07-01

    Full Text Available Abstract Background Research is needed to establish the utility of diagnostic interviews in clinical settings. Studies comparing clinical diagnoses with diagnoses generated with structured instruments show generally low or moderate agreement and clinical diagnostic assignment (e.g. admission or chart diagnoses are often considered to underdiagnose disorders. The objective of this study was to evaluate the impact of implementing the Schedule for Affective Disorders and Schizophrenia for School-Age Children – Present and Lifetime Version (Kiddie-SADS-PL into an in-patient adolescent clinical setting. Methods Participants were all adolescents admitted through the years 2001–2004 (N = 333 admissions, age 12–17 years. The authors reviewed the charts of the previous three years of consecutive admissions, patients being evaluated using routine psychiatric evaluation, before the Kiddie-SADS-PL was introduced. They then reviewed the charts of all consecutive admissions during the next twelve months, patients being evaluated by adding the instrument to routine practice. Results The rates of several main diagnostic categories (depressive, anxiety, bipolar and disruptive disorders increased considerably, suggesting that those disorders were likely underreported when using non-structured routine assessment procedures. The rate of co-morbidity increased markedly as the number of diagnoses assigned to each patient increased. Conclusion The major differences in diagnostic assignment rates provide arguments for the utility of diagnostic interviews in inpatient clinical settings but need further research, especially on factors that affect clinical diagnostic assignment in "real world" settings.

    In this paper the anisotropy of anomalous scattering at the Br K-absorption edge in brominated nucleotides is investigated, and it is shown that this effect can give rise to a marked directional dependence of the anomalous signal strength in X-ray diffraction data. This implies that choosing the correct orientation for crystals of such molecules can be a crucial determinant of success or failure when using single- and multiple-wavelength anomalous diffraction (SAD or MAD) methods to solve their structure. In particular, polarized absorption spectra on an oriented crystal of a brominated DNA molecule were measured, and were used to determine the orientation that yields a maximum anomalous signal in the diffraction data. Out of several SAD data sets, only those collected at or near that optimal orientation allowed interpretable electron density maps to be obtained. The findings of this study have implications for instrumental choices in experimental stations at synchrotron beamlines, as well as for the development of data collection strategy programs.

  11. The roles of adolescent attentional bias and parental invalidation of sadness in significant illness: a comparison between eating disorders and chronic pain.

    Hughes-Scalise, Abby; Connell, Arin

    2014-08-01

    Biopsychosocial conceptualizations of eating disorders (EDs) suggest the combination of an individual's emotional vulnerability and invalidating environment increases the likelihood of developing pervasive emotion dysregulation, and subsequent use of ED behaviors to regulate emotion (Haynos & Fruzetti, 2011; Safer, Telch, & Chen, 2009). The current study aimed to provide initial support for this model in adolescent EDs, through examining the interaction between an adolescent's emotional vulnerability, indexed by attentional biases for emotions, and an invalidating family environment. Specifically, we examined the ability of this interaction to discriminate youth with EDs from a comparison group of youth with chronic pain diagnoses, who were used to control for the presence of non-specific effects of having any illness. Fifty adolescent girls (25 with EDs and 25 with chronic pain) completed an emotional dot-probe task assessing attentional biases for emotional faces, and parents completed the Emotions as a Child Scale (Magai, 1996; Klimes-Dougan et al., 2007) to assess response to teen emotion. Results showed that teen angry attentional bias moderated the relationship between parental response to sadness and teen ED status: for teens with high attention bias towards angry faces, maladaptive parental response to sadness predicted increased odds of ED status versus chronic pain status.

    The present study wanted to test the course of the urge for non-suicidal self-injury (UNSSI) and the urge for self-punishment (USP) when suppressing or accepting upcoming emotions in response to a sadness-inducing film clip in female participants with borderline personality disorder (BPD). Thirty-six women with BPD were allocated either to a condition in which they were asked to engage in expressive suppression or acceptance while watching a sadness-inducing film clip. Ratings of UNSSI, USP, and positive and negative emotions were assessed prior to the clip (baseline), immediately after it (t1) and after a 5min waiting period (t2), during which participants viewed landscape pictures. Additionally, physiological measures were obtained. Main results revealed a significant increase in UNSSI from baseline to t2 in the acceptance, but not in the suppression group. Furthermore, USP scores significantly increased from baseline to t2 in the acceptance, but not in the suppression condition. However, there was no differential impact on the sympathetic and parasympathetic branch depending on strategy. The results are in line with recent literature showing that expressive suppression in BPD may also have an adaptive function.

  16. Interspecific nest parasitism by chukar on greater sage-grouse

    Science.gov (United States)

    Fearon, Michelle L.; Coates, Peter S.

    2014-01-01

    Nest parasitism occurs when a female bird lays eggs in the nest of another and the host incubates the eggs and may provide some form of parental care for the offspring (Lyon and Eadie 1991). Precocial birds (e.g., Galliformes and Anseriformes) are typically facultative nest parasites of both their own and other species (Lyon and Eadie 1991). This behavior increases a female’s reproductive success when she parasitizes other nests while simultaneously raising her own offspring. Both interspecific and conspecific nest parasitism have been well documented in several families of the order Galliformes, particularly the Phasianidae (Lyon and Eadie 1991, Geffen and Yom-Tov 2001, Krakauer and Kimball 2009). The Chukar (Alectoris chukar) has been widely introduced as a game bird to western North America from Eurasia and is now well established within the Great Basin from northeastern California east to Utah and north to Idaho and Oregon (Christensen 1996). Over much of this range the Chukar occurs with other phasianids, including the native Greater Sage-Grouse (Centrocercus urophasianus), within sagebrush (Artemisia spp.) steppe (Christensen 1996, Schroeder et al. 1999, Connelly et al. 2000). Chukar typically exploit a broader range of habitats than do sage-grouse, but both species use the same species of sagebrush and other shrubs for nesting cover (Christensen 1996, Schroeder et al. 1999). Chukar are known to parasitize nests of other individuals of their own species (Geffen and Yom-Tov 2001), but we are unaware of reported evidence that Chukar may parasitize nests of sage-grouse. Here we describe a case of a Chukar parasitizing a sage-grouse nest in the sagebrush steppe of western Nevada.

    Rouleau, Dominique M; Mutch, Jennifer; Laflamme, Georges-Yves

    2016-01-01

    Greater tuberosity fractures of the humerus can be successfully treated nonsurgically in most patients. However, as little as 3 to 5 mm of superior greater tuberosity displacement may adversely affect rotator cuff biomechanics and lead to subacromial impingement in patients who are active. In these cases, surgical treatment is recommended. Multiple surgical techniques include open and arthroscopic options tailored to fracture morphology, and strategies for repair include the use of suture anchors, transosseous sutures, tension bands, and plates/screws. Three classification systems are commonly used to describe greater tuberosity fractures: the AO, Neer, and morphologic classifications. Several hypotheses have been discussed for the mechanism of greater tuberosity fractures and the deforming forces of the rotator cuff, and the use of advanced imaging is being explored.

    Full Text Available Background/Aim. According to the World Health Organization (WHO definition, congenital anomalies are all disorders of the organs or tissues, regardless of whether they are visible at birth or manifest in life, and are registered in the International Classification of Diseases. The aim of this study was to compare the incidence and structure of prenatally detected and clinically manifested congenital anomalies in the newborns in the region of Novi Sad (Province of Vojvodina, Serbia in the two distant years (1996 and 2006. Methods. This retrospective cohort study included all the children born at the Clinic for Gynecology and Obstetrics (Clinical Center of Vojvodina in Novi Sad during 1996 and 2006. The incidence and the structure of congenital anomalies were analyzed. Results. During 1996 there were 6,099 births and major congenital anomalies were found in 215 infants, representing 3.5%. In 2006 there were 6,628 births and major congenital anomalies were noted in 201 newborns, which is 3%. During 1996 there were more children with anomalies of musculoskeletal system, urogenital tract, with anomalies of the central nervous system and chromosomal abnormalities. During the year 2006 there were more children with cardiovascular anomalies, followed by urogenital anomalies, with significant decline in musculoskeletal anomalies. The distribution of the newborns with major congenital anomalies, regarding perinatal outcome, showed the difference between the studied years. In 2006 the increasing number of children required further investigation and treatment. Conclusions. There is no national registry of congenital anomalies in Serbia so the aim of this study was to enlight this topic. In the span of ten years, covering the period of the NATO campaign in Novi Sad and Serbia, the frequency of major congenital anomalies in the newborns was not increased. The most frequent anomalies observed during both years implied the musculosketelal, cardiovascular

      Harmony aesthetics is the key factor of aesthetical ideology in Ji Kang’s No Sadness in Music. On the basis of criticizing Confucianism’s music education and inheriting Taoist’s harmonious music idea, Ji Kang composed No Sadness in Music; On the basis of nature harmony, people use “harmony and proportion” theory to create harmonious rhythm, and put their emotion in it and the harmonious music naturally comes out; when we listen to the music, our inner emotion will be involved, and in the cooperation with Li(礼), music also can produce its aesthetic effect.%  “和”是嵇康《声无哀乐论》美学思想的核心。嵇康在批判儒家音乐教化思想、继承道家音乐自由和谐思想的基础上提出了“声无哀乐”的观点;在自然之和的基础上,人们运用“和比”的方式创作出了和谐的乐音组合,又将自身的情感融入其中,“和比”之音由此而生;人们在倾听和美之乐时,与之形成共鸣,内心情感便外在表现出来,同时,音乐亦在礼和乐的配合的潜移默化中达到了一定的审美作用

    2016-07-01

    This study examined whether sucrose, fructose, aspartame, and saccharin influences the association between obesity and glucose tolerance in 2856 adults from the NHANES III survey. Aspartame intake significantly influenced the association between body mass index (BMI) and glucose tolerance (interaction: P = 0.004), wherein only those reporting aspartame intake had a steeper positive association between BMI and glucose tolerance than those reporting no aspartame intake. Therefore, consumption of aspartame is associated with greater obesity-related impairments in glucose tolerance.

    CofA, a major pilin subunit of colonization factor antigen III (CFA/III), forms pili that mediate small-intestinal colonization by enterotoxigenic Escherichia coli (ETEC). In this study, the crystal structure of an N-terminally truncated version of CofA was determined by single-wavelength anomalous diffraction (SAD) phasing using five sulfurs in the protein. Given the counterbalance between anomalous signal strength and the undesired X-ray absorption of the solvent, diffraction data were collected at 1.5 Å resolution using synchrotron radiation. These data were sufficient to elucidate the sulfur substructure at 1.38 Å resolution. The low solvent content (29%) of the crystal necessitated that density modification be performed with an additional 0.9 Å resolution data set to reduce the phase error caused by the small sulfur anomalous signal. The CofA structure showed the αβ-fold typical of type IVb pilins and showed high structural homology to that of TcpA for toxin-coregulated pili of Vibrio cholerae, including spatial distribution of key residues critical for pilin self-assembly. A pilus-filament model of CofA was built by computational docking and molecular-dynamics simulation using the previously reported filament model of TcpA as a structural template. This model revealed that the CofA filament surface was highly negatively charged and that a 23-residue-long loop between the α1 and α2 helices filled the gap between the pilin subunits. These characteristics could provide a unique binding epitope for the CFA/III pili of ETEC compared with other type IVb pili.

    Takata, K; Maniwa, S; Ochi, M

    1999-01-01

    Eleven patients with high-standing greater trochanter (13 joints) aged 13-36 years underwent surgery. Distal transfer of the greater trochanter (group T) was performed in 4 patients (5 joints) and lateral displacement osteotomy (group L) in 7 (8 joints). The average follow-up duration was 13.4 years in group T and 5.9 years in group L. Clinical results were evaluated by the hip score according to Merle d'Aubigne. The mean hip score in group T was 13.4 points before operation and 15.4 points after operation, and in group L, 12.8 and 17.4 points, respectively. The postoperative clinical results of group L were significantly better than those of group T (P = 0.0494). In radiological evaluation, although the articulo-trochanteric distance (ATD) increased in both groups in group L it improved remarkably from 9.8 to 24.3, indicating a large descending distance of the greater trochanter. The lever arm ratio (LAR) did not change significantly in group T, but it decreased from 1.97 to 1.60 in group L (P = 0.004). This means that the lever arm of the abductors can certainly be extended by lateral displacement osteotomy. Lateral displacement osteotomy is the most effective procedure for high-standing greater trochanter.

    To evaluate, if possible, the radiographic features of tuberculous osteitis in the greater trochanter and ischium, and to determine the cause of the lesions. We reterospectively reviewed the plain radiographic findings of 14 ptients with histologically proven tuberculous osteitis involving the greater trochanter and ischium. In each case, the following were analyzed:morphology of bone destruction, including cortical erosion;periosteal reaction;presence or abscence of calcific shadows in adjacent soft tissue. On the basis of an analysis of radiographic features and correlation of the anatomy with adjacent structures we attempted to determine causes. Of the 14 cases evaluated, 12 showed varrious degrees of extrinsic erosion on the outer cortical bone of the greater trochanter and ischium ; in two cases, bone destruction was so severe that the radiographic features of advanced perforated osteomyelitis were simulated. In addition to findings of bone destruction, in these twelve cases, the presence of sequestrum or calcific shadows was seen in adjacent soft tissue. Tuberculous osteitis in the greater trochanter and ischium showed the characteristic findings of chronic extrinsic erosion. On the basis of these findings we can suggest that these lesions result from an extrinsic pathophysiologic cause such as adjacent bursitis.

    We report an instructive case of a 65-year-old man who presented with a dumb-bell shaped tuberculous abscess across the greater sciatic notch bilaterally compressing both sciatic nerves. Clinical symptoms progressed slowly and mimicked lumbar radiculopathy, thus delaying an accurate diagnosis. Anterolateral retroperitoneal and posterolateral gluteal approaches of the greater sciatic notch as well as the acetabulum on both sides were followed in order to provide safe viewing and resection of the abscess. The abscess wall was adherent to the sciatic nerve and surrounding blood vessels. The symptoms completely disappeared after resection of the abscess.

  4. Trafficking in persons and development: towards greater policy coherence.

    Science.gov (United States)

    Danailova-Trainor, Gergana; Laczko, Frank

    2010-01-01

    Poverty is often regarded as the "root cause" of trafficking, but the linkages between poverty, a lack of development and trafficking are complex. For example, there is some evidence to suggest that victims of cross-border trafficking are more likely to originate from middle-income rather than lower-income countries. Trafficking and development have tended to be treated as very separate policy areas and the assessment of the development impact of counter-trafficking programmes is still at an early stage. This paper outlines a possible framework for a more evidence-based approach to understanding the linkages between trafficking, trafficking policy and human development. The paper argues that the human development gains from greater mobility could be significantly enhanced if there was greater coherence between policies to combat trafficking and policies to promote development.

  8. Integrating parasitology and marine ecology: Seven challenges towards greater synergy

    Science.gov (United States)

    Poulin, Robert; Blasco-Costa, Isabel; Randhawa, Haseeb S.

    2016-07-01

    Despite their very different historical origins as scientific disciplines, parasitology and marine ecology have already combined successfully to make important contributions to our understanding of the functioning of natural ecosystems. For example, robust assessments of the contribution of parasites to ecosystem biomass and energetics, and of their impact on community-wide biodiversity and food web structure, have all been made for the first time in marine systems. Nevertheless, for the marriage between parasitology and marine ecology to remain fruitful, several challenges must first be overcome. We discuss seven such challenges on the road to a greater synergy between these disciplines: (1) Raising awareness of parasitism as an ecological force by increasing the proportion of articles about parasites and diseases in marine ecology journals; (2) Making greater use of theory and conceptual frameworks from marine ecology to guide parasitological research; (3) Speeding up or at least maintaining the current rate at which marine parasites are found and described; (4) Elucidating a greater proportion of life cycles in all major groups of marine parasites; (5) Increasing the number of host-parasite model systems on which our knowledge is based; (6) Extending parasitological research offshore and into ocean depths; and (7) Developing, as needed, new epidemiological theory and transmission models for the marine environment. None of these challenges is insurmountable, and addressing just a few of them should guarantee that parasitology and marine ecology will continue to join forces and make further substantial contributions.

    2013-04-01

    Dietary phosphorus consumption has risen steadily in the United States. Oral phosphorus loading alters key regulatory hormones and impairs vascular endothelial function, which may lead to an increase in left ventricular mass (LVM). We investigated the association of dietary phosphorus with LVM in 4494 participants from the Multi-Ethnic Study of Atherosclerosis, a community-based study of individuals who were free of known cardiovascular disease. The intake of dietary phosphorus was estimated using a 120-item food frequency questionnaire and the LVM was measured using magnetic resonance imaging. Regression models were used to determine associations of estimated dietary phosphorus with LVM and left ventricular hypertrophy (LVH). Mean estimated dietary phosphorus intake was 1167 mg/day in men and 1017 mg/day in women. After adjustment for demographics, dietary sodium, total calories, lifestyle factors, comorbidities, and established LVH risk factors, each quintile increase in the estimated dietary phosphate intake was associated with an estimated 1.1 g greater LVM. The highest gender-specific dietary phosphorus quintile was associated with an estimated 6.1 g greater LVM compared with the lowest quintile. Higher dietary phosphorus intake was associated with greater odds of LVH among women, but not men. These associations require confirmation in other studies.

    Full Text Available The article presents the origins and development of the idea of absenteeism in Greater Poland in the 19th century. The start date for the research is 1840, which is considered to be a breakthrough year in the history of an organized absenteeism movement in Greater Poland. It was due to the Association for the Suppression of the Use of Vodka (Towarzystwo ku Przytłumieniu Używania Wódki in the Great Duchy of Posen that was then established in Kórnik. It was a secular organization that came into being on an initiative of doctor De La Roch, who was a German surgeon of a French origin. However, as early as 1844, the idea of absenteeism raised an interest of catholic clergymen of Greater Poland with high ranking clergy such as Rev. Leon Michał Przyłuski, Archbishop of Gniezno and Rev. Jan Kanty Dąbrowski, Archbishop of Posen, and later on Archbishops Rev. Mieczysław Halka Ledóchowski and Rev. Florian Oksza Stablewski. They were fascinated with activities of Rev. Jan Nepomucen Fick, Parish Priest of Piekary Śląskie and several other priests on whose initiative a lot of church brotherhoods of so called holy continence were set up in Upper Silesia as early as the first half-year of 1844. It was due to Bishop Dąbrowski that 100 000 people took vows of absenteeism in 1844–1845, becoming members of brotherhoods of absenteeism. In turn, it was an initiative of Archbishop Przyłuski that Jesuit missionaries – Rev. Karol Bołoz Antoniewicz, Rev. Teofil Baczyński and Rev. Kamil Praszałowicz, arrived in Greater Poland from Galicia in 1852 to promote the idea of absenteeism. Starting from 1848, they were helping Silesian clergymen to spread absenteeism. Clergymen of Greater Poland were also active in secular absenteeism associations. They became involved in the workings of the Association for the Promotion of Absenteeism that was set up by Zygmunt Celichowski in Kórnik in 1887, and especially in the Jutrzenka Absenteeism Association

    Full Text Available Introduction. Gossypiboma (GP is a term used to express the mass resulting from forgotten cotton sponge in operations. Rarely, a transmural migration may occur into the gastrointestinal lumen without creating any defect by GP. Laparotomy or endoscopic removal may be required, by the way it can be taken out of the body itself by intestinal ways. In this study, we reported a case of mechanical intestinal obstruction causing GP. Case. The fifty-one-year-old female patient admitted to the emergency department with the complaints of mechanical intestinal obstruction and had a history of open cholecystectomy 20 years ago. There were the findings of intestinal obstruction in abdominal plain radiography and computerized tomography. The sponge that obstructed the lumen completely 40 cm proximal to the ileocecal valve was identified in the laparotomy with the diagnosis of brid ileus. The small intestine was closed over double-fold after removal of sponge. Transmural migration of abdominal-remained sponge was thought to be occurred without creating a defect after cholecystectomy. Postoperatively, the patient was discharged without having any problems at 4th day of hospitalization. Conclusion. Although it is a rare situation in routine clinical practice, GP should be considered as a differential diagnosis in the patients who had a diagnosis of mechanical intestinal obstruction, and laparotomy was applied before. As GP may lead to situations which cause mortality, all precautions should be taken to prevent it.

    2005-01-01

    A new land cover database of Greater Mesoamerica has been prepared using moderate resolution imaging spectroradiometer (MODIS, 500 m resolution) satellite data. Daily surface reflectance MODIS data and a suite of ancillary data were used in preparing the database by employing a decision tree classification approach. The new land cover data are an improvement over traditional advanced very high resolution radiometer (AVHRR) based land cover data in terms of both spatial and thematic details. The dominant land cover type in Greater Mesoamerica is forest (39%), followed by shrubland (30%) and cropland (22%). Country analysis shows forest as the dominant land cover type in Belize (62%), Cost Rica (52%), Guatemala (53%), Honduras (56%), Nicaragua (53%), and Panama (48%), cropland as the dominant land cover type in El Salvador (60.5%), and shrubland as the dominant land cover type in Mexico (37%). A three-step approach was used to assess the quality of the classified land cover data: (i) qualitative assessment provided good insight in identifying and correcting gross errors; (ii) correlation analysis of MODIS- and Landsat-derived land cover data revealed strong positive association for forest (r2 = 0.88), shrubland (r2 = 0.75), and cropland (r2 = 0.97) but weak positive association for grassland (r2 = 0.26); and (iii) an error matrix generated using unseen training data provided an overall accuracy of 77.3% with a Kappa coefficient of 0.73608. Overall, MODIS 500 m data and the methodology used were found to be quite useful for broad-scale land cover mapping of Greater Mesoamerica.

    We present a synthesis of the state of knowledge concerning the species of Passalidae (Coleoptera) of the West Indies and we present a key to the species. The recently described genus Antillanax Boucher renders the subgenus Passalus (Pertinax) Kaup paraphyletic, therefore we place Antillanax in synonymy with Passalus (Pertinax) and we propose a new combination for Passalus (Pertinax) doesburgi (Boucher). The island richest in species is Hispaniola, with five species, three of them endemic. Excluding Trinidad and Tobago, the passalid fauna of the West Indies comprises 13 species; this is low richness, but with high endemism (50%), especially for the Greater Antilles.

    Aim: Greater sage-grouse (Centrocercus urophasianus), a shrub-steppe obligate species of western North America, currently occupies only half its historical range. Here we examine how broad-scale, long-term trends in landscape condition have affected range contraction. Location: Sagebrush biome of the western USA. Methods: Logistic regression was used to assess persistence and extirpation of greater sage-grouse range based on landscape conditions measured by human population (density and population change), vegetation (percentage of sagebrush habitat), roads (density of and distance to roads), agriculture (cropland, farmland and cattle density), climate (number of severe and extreme droughts) and range periphery. Model predictions were used to identify areas where future extirpations can be expected, while also explaining possible causes of past extirpations. Results: Greater sage-grouse persistence and extirpation were significantly related to sagebrush habitat, cultivated cropland, human population density in 1950, prevalence of severe droughts and historical range periphery. Extirpation of sage-grouse was most likely in areas having at least four persons per square kilometre in 1950, 25% cultivated cropland in 2002 or the presence of three or more severe droughts per decade. In contrast, persistence of sage-grouse was expected when at least 30 km from historical range edge and in habitats containing at least 25% sagebrush cover within 30 km. Extirpation was most often explained (35%) by the combined effects of peripherality (within 30 km of range edge) and lack of sagebrush cover (less than 25% within 30 km). Based on patterns of prior extirpation and model predictions, we predict that 29% of remaining range may be at risk. Main Conclusions: Spatial patterns in greater sage-grouse range contraction can be explained by widely available landscape variables that describe patterns of remaining sagebrush habitat and loss due to cultivation, climatic trends, human

    2003-04-01

    The founders of the Association of Academic Health Sciences Libraries (AAHSL) envisioned the development of a professional organization that would provide a greater voice for academic health sciences libraries, facilitate cooperation and communication with the Association of American Medical Colleges, and create a forum for identifying problems and solutions that are common to academic health sciences libraries. This article focuses on the fulfillment of the "greater voice" vision by describing action and leadership by AAHSL and its members on issues that directly influenced the role of academic health sciences libraries. These include AAHSL's participation in the work that led to the publication of the landmark report, Academic Information in the Academic Health Sciences Center: Roles for the Library in Information Management; its contributions to the recommendations of the Physicians for the Twenty-first Century: The GPEP Report; and the joint publication with the Medical Library Association of Challenge to Action: Planning and Evaluation Guidelines for Academic Health Sciences Libraries.

    This report contains an assessment of the radiological impact on the Greater London population of postulated accidental releases from the Sizewell PWR. Three of the degraded core accident releases postulated by the CEGB are analysed. The consequences, conditional upon each release, are evaluated in terms of the health impact on the exposed population and the impact of countermeasures taken to limit the exposure. Consideration is given to the risk to the Greater London population as a whole and to individuals within it. The consequences are evaluated using the NRPB code MARC (Methodology for Assessing Radiological Consequences). The results presented in this report are all conditional upon the occurrence of each release. In assessing the significance of the results, due account must be taken of the frequency with which such releases may be predicted to occur.

    Primary Ewing's sarcoma of the skull is a very rare entity. We report MRI findings in a case of Ewing's sarcoma of the greater wing of sphenoid in a 4-year-old patient. Magnetic resonance imaging showed markedly heterogenous signal intensity with areas of haemorrhage and necrosis. It also demonstrated the exact extent of tumour due to its multiplanar capabilities and was, therefore, helpful in planning surgery.

    This study examined parental emotion socialization processes associated with adolescent unipolar depressive disorder. Adolescent participants (N=107; 42 boys) were selected either to meet criteria for current unipolar depressive disorder or to be psychologically healthy as defined by no lifetime history of psychopathology or mental health treatment and low levels of current depressive symptomatology. A multisource/method measurement strategy was used to assess mothers’ and fathers’ responses to adolescent sad and angry emotion. Each parent and the adolescents completed questionnaire measures of parental emotion socialization behavior, and participated in meta-emotion interviews and parent-adolescent interactions. As hypothesized, parents of adolescents with depressive disorder engaged in fewer supportive responses and more unsupportive responses overall relative to parents of nondepressed adolescents. Between group differences were more pronounced for families of boys, and for fathers relative to mothers. The findings indicate that parent emotion socialization is associated with adolescent depression and highlight the importance of including fathers in studies of emotion socialization, especially as it relates to depression.

    Full Text Available Music is a potent source for eliciting emotions, but not everybody experience emotions in the same way. Individuals with autism spectrum disorder (ASD show difficulties with social and emotional cognition. Impairments in emotion recognition are widely studied in ASD, and have been associated with atypical brain activation in response to emotional expressions in faces and speech. Whether these impairments and atypical brain responses generalize to other domains, such as emotional processing of music, is less clear. Using functional magnetic resonance imaging, we investigated neural correlates of emotion recognition in music in high-functioning adults with ASD and neurotypical adults. Both groups engaged similar neural networks during processing of emotional music, and individuals with ASD rated emotional music comparable to the group of neurotypical individuals. However, in the ASD group, increased activity in response to happy compared to sad music was observed in dorsolateral prefrontal regions and in the rolandic operculum/insula, and we propose that this reflects increased cognitive processing in response to emotional musical stimuli in this group.

    Full Text Available Juvenile crime is constantly attracting the attention of the general and professional public and in some way is an indicator of the success or failure of all measures by which a society takes care of the young. As a particularly vulnerable category, juveniles are the focus of special attention in each society which constantly invents always new and more efficient ways of solving criminal matters which will cause a minimum damage to a juvenile offender, and achieve the purpose that is reflected in the strengthening of its personal responsibility for its actions. In this sense, a special place occupies the application of educational orders that can achieve its purpose only if there is a complete legal regulation of their use (law and regulations and systematically provided logistics. Imposition and implementation of educational orders is directly related to the examination of juvenile's personality and a special attention has been paid to this issue. In this work, the author deals with educational orders as a diversionary treatment model against juvenile offenders, as well as the implementation of educational orders in the practice of the Higher Public Prosecutor's Office and the High Court in Novi Sad.

    Full Text Available Candidemia is an important emerging nosocomial infection in patients with risk factors. Candida species from nonsterile sites can give insight into the characteristics of strains that may cause invasive disease. The aim of this study was to evaluate antifungal susceptibility of Candida blood and fecal isolates in Novi Sad, Vojvodina. During a 3-year period (2008 to 2010, 424 isolates of Candida spp. were collected, 30 bloodstream isolates and 394 strains from fecal samples. In vitro susceptibility of these isolates to five antifungal agents was established using commercial ATB FUNGUS 3 (Bio-Mérieux. Predominant species was Candida albicans (6 isolates from blood and 269 from feces. Resistance to one or more antifungal agents was less common in Candida albicans (3.63% than in other species (24.83%. Resistance to itraconazole was the most commonly found in both groups of isolates, 9.64% strains from feces and 20% from blood samples. Twelve isolates were multiply resistant, usually to fluconazole, itraconazole, and voriconazole. Resistance to amphotericine B was extremely rare. Although resistance to antimycotics of Candida spp. is rare at present, continued surveillance of antifungal susceptibility is necessary in order to monitor trends, and to choose the right empiric therapy.

    Dehydration affects almost all the physiological processes including those that result in the accumulation of misfolded proteins in the endoplasmic reticulum (ER), which in turn elicits a highly conserved signaling, the unfolded protein response (UPR). We investigated the dehydration-responsive membrane-associated proteome of a legume, chickpea, by 2-DE coupled with mass spectrometry. A total of 184 protein spots were significantly altered over a dehydration treatment of 120 h. Among the differentially expressed proteins, a non-canonical SUN domain protein, designated CaSUN1 (Cicer arietinum Sad1/UNC-84), was identified. CaSUN1 localized to the nuclear membrane and ER, besides small vacuolar vesicles. The transcripts were downregulated by both abiotic and biotic stresses, but not by abscisic acid treatment. Overexpression of CaSUN1 conferred stress tolerance in transgenic Arabidopsis. Furthermore, functional complementation of the yeast mutant, slp1, could rescue its growth defects. We propose that the function of CaSUN1 in stress response might be regulated via UPR signaling.

    The Ballad of the Sad Café is a representative work of American novelist Carson McCullers.In this novella McCullers made full use of the narrative characteristics of the ballad,not only because this genre with its repetive structure summarized the feature and the impersonal narrators and catered to the author’s specific requirements in composing the story to display the motif,but also because the historical period in which she lived entailed a considerable aesthetic distance between the author and her text.%《伤心咖啡馆之歌》是美国南方女作家卡森·麦卡勒斯的代表作。小说中,麦卡勒斯充分利用了民谣体的叙事特点来展开写作,不仅因为民谣体的重复结构、"概要式"特点和叙述者所体现的"非个人化"特征有助于其对创作主旨展开充分论述,还因为她所处的特定历史时期的时代精神要求作者与文本保持一定的审美距离。

  5. The Gac-Rsm and SadB signal transduction pathways converge on AlgU to downregulate motility in Pseudomonas fluorescens.

    Directory of Open Access Journals (Sweden)

    Francisco Martínez-Granero

    Full Text Available Flagella mediated motility in Pseudomonas fluorescens F113 is tightly regulated. We have previously shown that motility is repressed by the GacA/GacS system and by SadB through downregulation of the fleQ gene, encoding the master regulator of the synthesis of flagellar components, including the flagellin FliC. Here we show that both regulatory pathways converge in the regulation of transcription and possibly translation of the algU gene, which encodes a sigma factor. AlgU is required for multiple functions, including the expression of the amrZ gene which encodes a transcriptional repressor of fleQ. Gac regulation of algU occurs during exponential growth and is exerted through the RNA binding proteins RsmA and RsmE but not RsmI. RNA immunoprecipitation assays have shown that the RsmA protein binds to a polycistronic mRNA encoding algU, mucA, mucB and mucD, resulting in lower levels of algU. We propose a model for repression of the synthesis of the flagellar apparatus linking extracellular and intracellular signalling with the levels of AlgU and a new physiological role for the Gac system in the downregulation of flagella biosynthesis during exponential growth.

  6. The State of Lithospheric Stress in Greater Thailand

    Thailand and its surrounding regions occupy an important, but often overlooked, location in terms of plate tectonics and lithospheric deformation. The lateral extrusion of Tibet southeastward and eastward along deep strike slip faults to the north and the Sumatra-Andaman subduction zone to the south and west bound the region of greater Thailand. While it is adjacent to some of the most seismically active plate boundaries and intra-plate regions on Earth, this region has experienced only a low level of background seismicity. Thus, the long-term seismic potential of greater Thailand remains highly uncertain. Although historic seismicity is one indicator for future seismicity it is not the only tool we have for determining seismic hazard; we can assess the state of lithospheric stress. The stress conditions in this apparent aseismic region will be controlled by the forces acting on it boundaries. We can analyze those conditions through a study of fault structure, earthquake activity, and kinematics in the boundary area. Using Global Seismic Network (GSN) data augmented with Thai seismic network data to constrain the kinematics, and numerical finite element modeling of crustal and lithospheric deformation of the region, we are able to determine to overall stress conditions. This stress model can be compared to the known fault states in Thailand to assess the potential for earthquake activity.

    Phosphate-binding proteins (PBPs) are key proteins that belong to the bacterial ABC-type phosphate transporters. PBPs are periplasmic (or membrane-anchored) proteins that capture phosphate anions from the environment and release them to the transmembrane transporter. Recent work has suggested that PBPs have evolved for high affinity as well as high selectivity. In particular, a short, unique hydrogen bond between the phosphate anion and an aspartate residue has been shown to be critical for selectivity, yet is not strictly conserved in PBPs. Here, the PBP fromPolaromonasJS666 is focused on. Interestingly, this PBP is predicted to harbor different phosphate-binding residues to currently known PBPs. Here, it is shown that the PBP fromPolaromonasJS666 is capable of binding phosphate, with a maximal binding activity at pH 8. Its structure is expected to reveal its binding-cleft configuration as well as its phosphate-binding mode. Here, the expression, purification, characterization, crystallization and X-ray diffraction data collection to 1.35 Å resolution of the PBP fromPolaromonasJS666 are reported.

    Music can induce particular emotions and activate semantic knowledge. In the semantic variant of primary progressive aphasia (svPPA), semantic memory is impaired as a result of anterior temporal lobe (ATL) atrophy. Semantics is responsible for the encoding and retrieval of factual knowledge about music, including associative and emotional attributes. In the present study, we report the performance of two individuals with svPPA in three experiments. NG with bilateral ATL atrophy and ND with atrophy largely restricted to the left ATL. Experiment 1 assessed the recognition of musical excerpts and both patients were unimpaired. Experiment 2 studied the emotions conveyed by music and only NG showed impaired performance. Experiment 3 tested the association of semantic concepts to musical excerpts and both patients were impaired. These results suggest that the right ATL seems essential for the recognition of emotions conveyed by music and that the left ATL is involved in binding music to semantics. They are in line with the notion that the ATLs are devoted to the binding of different modality-specific properties and suggest that they are also differentially involved in the processing of factual and emotional knowledge associated with music.

  10. Feeling Happy and Sad at the Same Time? Subcultural Differences in Experiencing Mixed Emotions between Han Chinese and Mongolian Chinese.

    Sometimes people experience pleasant and unpleasant emotions at the same time in a single emotional event. Previous cross-cultural studies indicated that such mixed emotions are more prevalent in China and related to the attitudes toward happiness and individual's regulatory motivation. However, China is a multi-ethnic country and not much is known about subcultural differences in mixed emotions. The aim of this study was to examine the role that implicit attitudes toward happiness and regulatory motivation played in regard of the subcultural differences in mixed emotions between Han (N = 61) and Mongolian Chinese (N = 46). Results indicated that, compared with Mongolian Chinese, Han Chinese showed stronger associations between implicit contra-hedonic attitudes toward happiness and mixed emotions during pleasant emotional events. Also, Han Chinese who reported contra-hedonic motivation during pleasant emotional events had higher levels of mixed emotions than those who had hedonic motivation. No significant differences were found in terms of mixed emotions between Mongolian Chinese who had contra-hedonic and hedonic motivation. These results suggest that the psychological mechanisms underlying differences in mixed emotions also require a more comprehensive understanding from a subcultural perspective.

    Purpose - As opposed to the predominant belief in the West, in Chinese dominated societies theremay be a positive relationship between age and perceived possession of high quality personalresources. That attitude towards old age may carry over to expatriates in Chinese societies. This mayhave...... a positive impact on expatriates' job performance. Therefore, the purpose of this paper is toexamine the association between the age of business expatriates and their work performance in a Chinese cultural setting. Design/methodology/approach - Controlling for the potential bias of a number of background...... with the age of the expatriates. This finding provides partial affirmative support to the presumption that the age of business expatriates matters in a Chinese cultural context. Practical implications - Companies sending expatriates to Greater China could introduce age among other selection criteria. At least...

    A high-speed rotation instrument to produce centrifugal fields greater than 100 million times gravity has been constructed. Small, solid, spherical high-carbon chromium steel rotors are suspended magnetically in high vacuum and spun by a rotating magnetic field. It is found that the spinning rotor explodes when the calculated average value of stress in the meridian plane reaches about 1.2 times the tensile strength of the material. The maximum speed of rotation so far achieved for more than a few days without bursting was obtained with a rotor of 1.50 mm diameter. The speed of 2.11 x 10(5) rev/s corresponded to a centrifugal field of 1.34 x 10(8) times gravity. Our instrument will find application in the study of nuclear atomic phenomena.

    2004-01-01

    I examined the relationship of recalled and diary recorded frequency of penile-vaginal intercourse (FSI), noncoital partnered sexual activity, and masturbation to measured waist and hip circumference in 120 healthy adults aged 19-38. Slimmer waist (in men and in the sexes combined) and slimmer hips (in men and women) were associated with greater FSI. Slimmer waist and hips were associated with rated importance of intercourse for men. Noncoital partnered sexual activity had a less consistent association with slimness. Slimmer waist and hips were associated with less masturbation (in men and in the sexes combined). I discuss the results in terms of differences between different sexual behaviors, attractiveness, emotional relatedness, physical sensitivity, sexual dysfunction, sociobiology, psychopharmacological aspects of excess fat and carbohydrate consumption, and implications for sex therapy.

  14. Risks of Brucella abortus spillover in the Greater Yellowstone area.

    2013-04-01

    Recurrent spillover of Brucella abortus from wildlife reservoirs to domestic cattle in the Greater Yellowstone Area (GYA) has prevented the United States from completely eradicating bovine brucellosis. Risks to cattle are a function of the size and location of wildlife and livestock populations, the degree and nature of spatio-temporal interactions between the various hosts, the level of disease in wildlife, and the susceptibility of livestock herds. While the brucellosis prevalence in wild, free-ranging GYA bison (Bison bison) is high, current management actions have successfully limited contact between bison and cattle. Under current management practices, the risks to cattle in the GYA are predominantly from wild elk (Cervus elaphus). Intra- and inter-species transmission events, while uncommon, are nevertheless crucial for the maintenance of brucellosis in the GYA. Future management actions should focus on decreasing elk herd densities and group sizes and on understanding the behavioural and environmental drivers that result in co-mingling that makes transmission possible.

    The Greater Plains Collaborative (GPC) is composed of 10 leading medical centers repurposing the research programs and informatics infrastructures developed through Clinical and Translational Science Award initiatives. Partners are the University of Kansas Medical Center, Children's Mercy Hospital, University of Iowa Healthcare, the University of Wisconsin-Madison, the Medical College of Wisconsin and Marshfield Clinic, the University of Minnesota Academic Health Center, the University of Nebraska Medical Center, the University of Texas Health Sciences Center at San Antonio, and the University of Texas Southwestern Medical Center. The GPC network brings together a diverse population of 10 million people across 1300 miles covering seven states with a combined area of 679 159 square miles. Using input from community members, breast cancer was selected as a focus for cohort building activities. In addition to a high-prevalence disorder, we also selected a rare disease, amyotrophic lateral sclerosis.

    We propose that dishonest and creative behavior have something in common: They both involve breaking rules. Because of this shared feature, creativity may lead to dishonesty (as shown in prior work), and dishonesty may lead to creativity (the hypothesis we tested in this research). In five experiments, participants had the opportunity to behave dishonestly by overreporting their performance on various tasks. They then completed one or more tasks designed to measure creativity. Those who cheated were subsequently more creative than noncheaters, even when we accounted for individual differences in their creative ability (Experiment 1). Using random assignment, we confirmed that acting dishonestly leads to greater creativity in subsequent tasks (Experiments 2 and 3). The link between dishonesty and creativity is explained by a heightened feeling of being unconstrained by rules, as indicated by both mediation (Experiment 4) and moderation (Experiment 5).

    Looking across human societies reveals regularities in the languages that people speak and the concepts that they use. One explanation that has been proposed for these "cultural universals" is differences in the ease with which people learn particular languages and concepts. A difference in learnability means that languages and concepts possessing a particular property are more likely to be accurately transmitted from one generation of learners to the next. Intuitively, this difference could allow languages and concepts that are more learnable to become more prevalent after multiple generations of cultural transmission. If this is the case, the prevalence of languages and concepts with particular properties can be explained simply by demonstrating empirically that they are more learnable. We evaluate this argument using mathematical analysis and behavioral experiments. Specifically, we provide two counter-examples that show how greater learnability need not result in a property becoming prevalent. First, more learnable languages and concepts can nonetheless be less likely to be produced spontaneously as a result of transmission failures. We simulated cultural transmission in the laboratory to show that this can occur for memory of distinctive items: these items are more likely to be remembered, but not generated spontaneously once they have been forgotten. Second, when there are many languages or concepts that lack the more learnable property, sheer numbers can swamp the benefit produced by greater learnability. We demonstrate this using a second series of experiments involving artificial language learning. Both of these counter-examples show that simply finding a learnability bias experimentally is not sufficient to explain why a particular property is prevalent in the languages or concepts used in human societies: explanations for cultural universals based on cultural transmission need to consider the full set of hypotheses a learner could entertain and all of

    Over one-third of breast cancer survivors experience upper extremity disability. Black women present with factors associated with greater upper extremity disability, including: increased body mass index (BMI), more advanced disease stage at diagnosis, and varying treatment type compared with Whites. No prior research has evaluated the relationship between race and upper extremity disability using validated tools and controlling for these factors. Data were drawn from a survey study among 610 women with stage I-III hormone receptor positive breast cancer. The disabilities of the arm, shoulder and hand (QuickDASH) is an 11-item self-administered questionnaire that has been validated for breast cancer survivors to assess global upper extremity function over the past 7 days. Linear regression and mediation analysis estimated the relationships between race, BMI and QuickDASH score, adjusting for demographics and treatment types. Black women (n = 98) had 7.3 points higher average QuickDASH scores than White (n = 512) women (p education, cancer treatment, months since diagnosis, and aromatase inhibitor status, Black women had an average 4-point (95 % confidence interval 0.18-8.01) higher QuickDASH score (p = 0.04) than White women. Mediation analysis suggested that BMI attenuated the association between race and disability by 40 %. Even several years post-treatment, Black breast cancer survivors had greater upper extremity disability, which was partially mediated by higher BMIs. Close monitoring of high BMI Black women may be an important step in reducing disparities in cancer survivorship. More research is needed on the relationship between race, BMI, and upper extremity disability.

    Full Text Available Globally, the responsible factors for the ongoing development of urbanization are the high speed of population growth, and the mass migration of humans to cities and large urban areas. In most countries, this process resulted in the emergence of ‘pseudo-urbanization’ which is difficult to be regulated. The purpose of the carried researches to determine the development priorities in the territory of Greater Baku – the capital city of the Republic of Azerbaijan; to define the problems that take place in this connection; and to develop ways of elimination of these problems. The reason of taking Baku as a research area is connected with some of the factors. Firstly, studies on Baku have been conducted based on the Soviet geographical and urban planning school and their methods for a long period. In this regard, it is necessary to carry out research in this field based on the principles adopted in most countries. Secondly, since 1992, the intensive accumulation of population in the territory of the capital city and the surrounding areas is being observed because of socio-economic problems. As a result, the process of pseudo-urbanization intensified, entailing a densely-populated area. Thirdly, low-rise buildings still continue to exist in the large areas within the territory of Baku, and they are not associated with the functional structure of the city. This situation creates many challenges, particularly in terms of density growth and effective use of the city’s territory. Finally, numerous new buildings have been constructed in the residential areas of Baku in recent years, and this may entailserious problems in water supply, energy provision, and utilities. The study is carried out referring to previous works of researchers, statistic data, and the results of the population census conducted in 1959-2009.The practical significance of the scientific work is that positive and negative factors affecting the further development of Greater Baku

    ;and managing reactions through confrontive emotional coping, reflection on emotions, and seeking social support (proactive emotion regulation).All participants completed Eysenck Personality Questionnaire-Revised Short Scale for Chinese (EPQ-RSC). The results showed that (1) Older adults reported the same experiences of sadness as younger adults when the education level was a covariate variable. Older adults used more passive emotion-regulation strategies than younger adults (2) the passive emotion-regulation strategy in older adults not only was affected by age, but also was significantly predicted by the experience of sadness, (3) there was a significant positive correlation between sadness experience and neuroticism of personality traits in older adults, and (4) the passive emotion-regulation strategy was significantly predicted by the experience of sadness for old adults, but the effect of extraversion was not found in the case of younger adults. Extraversion of personality traits exercised the same effect on using proactive emotional regulation strategies for older adults as younger adults. The findings indicated the effect pattern of age and personality traits on the experience of sadness and emotion-regulation strategies in adults was different from that in younger adults in the context of everyday intrapersonal problems.

    Shortly after 09:00 h on 19 April 1995, the Alfred P. Murrah Federal Building, located in downtown Oklahoma City, was devastated with a bomb blast of such gigantic proportions that it was heard 60 miles away in neighbouring Norman, Oklahoma. Oklahomans routinely commuting to work on that sunny Wednesday morning went about their business as usual. A crude bomb chemically comprised of various organic compounds, chemical fertilizer, ammonium nitrate and diesel fuel, weighing an estimated 4800 pounds or more, was transported in a vehicle the size of a truck. It blew open a crater 6-8 ft deep in the street floor. The Murrah Federal Building was impacted immediately; floors, windows, communication equipment and almost all the innocent victims inside were razed to the ground. Outside the building, as far as 10 blocks away or more, hundreds of victims lay hurt, seriously injured or dead from shards of glass that flew from office windows hundreds of feet above the street floor. Without warning, the initial impact of the bomb immediately devastated the entire city. People were in a state of shock, disbelief and denial; acute symptoms of post traumatic stress disorder (PTSD) were commonplace. Oklahomans, 'numb' from the impact of the critical incident and ill-equipped to handle the chaos of such catastrophic proportions, struggled to regain control of their lives as friends, family and loved ones went unaccounted for or were found critically injured, dying or already dead. The critical incident on 19 April demanded the immediate attention of the nation, to come to the aid of the Oklahomans who were in desperate need. By 1 June, the exhaustive investigations revealed that 30 office buildings in downtown Oklahoma City had to be condemned, and as many as 300 others were damaged. In addition, 168 people had been found dead including 19 children and one nurse working as an emergency services rescue worker. Approximately 490 other victims had been reported injured from the blast

    Full Text Available Mesothelioma is the most common malignant primary tumor of the pleura and usually associated with inhalation of asbestos fibers. In contrast, peritoneal mesothelioma is a rare entity whose pathomechanism is not yet fully understood. The coexistence of pleural mesothelioma with secondary involvement of the abdominal cavity has not been addressed in the literature. In this case report, we describe secondary malignant mesothelioma of the greater omentum. A 69-year-old man with histologically proven pleural mesothelioma on the right side and no past medical history of asbestos exposure received palliative treatment consisting of a talc pleurodesis. After a 6-month interval of stable disease, a local progressive tumor of the right pleura was seen on a CT scan. Eleven months later, during follow-up, the patient presented at our emergency department with a sudden onset of diffuse abdominal pain. Abdominal ultrasound revealed a mass within the greater omentum and the coexistence of free fluid. Subsequent abdominal CT scans demonstrated tumor infiltration from the right pleura by a transdiaphragmatic route into the abdomen, where diffuse infiltration of the greater omentum was observed. Aspiration of the ascites and the biopsy of the greater omentum confirmed the diagnosis of secondary malignant mesothelioma of the peritoneum. In conclusion, we present the extremely rare diagnosis of secondary malignant mesothelioma of the abdomen, which arose as a result of local progression from the right pleura into the abdomen.

    In cases of displaced greater tuberosity fractures, treatments by arthroscopic-assisted reduction and percutaneous screw fixation have been reported. However, in cases in which there is a comminuted fracture or a minimally displaced fracture combined with concomitant lesions such as rotator cuff tear or labral pathology, it is difficult to reduce the fracture and to treat other pathologies by use of a percutaneous screw. Recently, many surgeons have used the double-row repair method in rotator cuff repair, which provides a tendon-bone interface better suited for biologic healing and restoring normal anatomy. In accordance with this method, we used the arthroscopic technique of double-row suture anchor fixation for a minimally displaced greater tuberosity fracture without additional incision. Initially, debridement was performed on the fracture surface by use of a shaver, and the medial-row anchor was inserted through the anterior portal or the intact cuff. Two lateral-row anchors were inserted just anterior and posterior to the lower margin of the fractured fragment under C-arm guidance. The medial-row sutures and lateral-row sutures were then placed. Arthroscopic double-row suture anchor fixation of a displaced greater tuberosity fracture restores the original footprint of the rotator cuff and normal tendon-bone interface of the displaced greater tuberosity fracture.

    Tokyo and its outlying cities are home to one-quarter of Japan's 127 million people. Highly destructive earthquakes struck the capital in 1703, 1855 and 1923, the last of which took 105 000 lives. Fuelled by greater Tokyo's rich seismological record, but challenged by its magnificent complexity, our joint Japanese-US group carried out a new study of the capital's earthquake hazards. We used the prehistoric record of great earthquakes preserved by uplifted marine terraces and tsunami deposits (17 M???8 shocks in the past 7000 years), a newly digitized dataset of historical shaking (10 000 observations in the past 400 years), the dense modern seismic network (300 000 earthquakes in the past 30 years), and Japan's GeoNet array (150 GPS vectors in the past 10 years) to reinterpret the tectonic structure, identify active faults and their slip rates and estimate their earthquake frequency. We propose that a dislodged fragment of the Pacific plate is jammed between the Pacific, Philippine Sea and Eurasian plates beneath the Kanto plain on which Tokyo sits. We suggest that the Kanto fragment controls much of Tokyo's seismic behaviour for large earthquakes, including the damaging 1855 M???7.3 Ansei-Edo shock. On the basis of the frequency of earthquakes beneath greater Tokyo, events with magnitude and location similar to the M??? 7.3 Ansei-Edo event have a ca 20% likelihood in an average 30 year period. In contrast, our renewal (time-dependent) probability for the great M??? 7.9 plate boundary shocks such as struck in 1923 and 1703 is 0.5% for the next 30 years, with a time-averaged 30 year probability of ca 10%. The resulting net likelihood for severe shaking (ca 0.9g peak ground acceleration (PGA)) in Tokyo, Kawasaki and Yokohama for the next 30 years is ca 30%. The long historical record in Kanto also affords a rare opportunity to calculate the probability of shaking in an alternative manner exclusively from intensity observations. This approach permits robust estimates

  7. Does unilateral transtibial amputation lead to greater metabolic demand during walking?

    Directory of Open Access Journals (Sweden)

    Elizabeth Russell Esposito, PhD

    2015-01-01

    Full Text Available Previous literature reports greater metabolic demand of walking following transtibial amputation. However, most research focuses on relatively older, less active, and often dysvascular amputees. Servicemembers with traumatic amputation are typically young, fit, and highly active before and often following surgical amputation of their lower limb. This study compared the metabolic demand of walking in young, active individuals with traumatic unilateral transtibial amputation (TTA and nondisabled controls. Heart rate (HR, rate of oxygen consumption, and rating of perceived exertion (RPE were calculated as subjects walked at a self-selected velocity and at five standardized velocities based on leg length. The TTA group completed a Prosthetics Evaluation Questionnaire. Oxygen consumption (p = 0.89, net oxygen consumption (p = 0.32, and RPE (p = 0.14 did not differ between groups. Compared with controls, HR was greater in the TTA group and increased to a greater extent with velocity (p < 0.001. Overall, the TTA group rated their walking abilities as high (mean: 93% out of 100%. This is the first study to report equivalent metabolic demand between persons with amputation and controls walking at the same velocity. These results may reflect the physical fitness of the young servicemembers with traumatic amputations and may serve to guide outcome expectations in the future.

  8. Views That Are Shared With Others Are Expressed With Greater Confidence and Greater Fluency Independent of Any Social Influence.

    2016-05-01

    Research on group influence has yielded a prototypical majority effect (PME): Majority views are endorsed faster and with greater confidence than minority views, with the difference increasing with majority size. The PME was attributed to conformity pressure enhancing confidence in consensual views and causing inhibition in venturing deviant opinions. Our results, however, indicate that PME for binary choices can arise from the process underlying confidence and latency independent of social influence. PME was demonstrated for tasks and conditions that are stripped of social relevance; it was observed in within-individual analyses in contrasting the individual's more frequent and less frequent responses to the same item, and was found for the predictions of others' responses. A self-consistency model, which assumes that choice and confidence are based on the sampling of representations from a commonly shared pool of representations, yielded a PME for confidence and latency. Behavioral implications of the results are discussed.

    Active geologic processes associated with the Yellowstone hotspot are fundamental in shaping the landscapes of the greater Yellowstone ecosystem (GYE), a high volcanic plateau flanked by a crescent of still higher mountainous terrain. The processes associated with the Yellowstone hotspot are volcanism, faulting, and uplift and are observed in the geology at the surface. We attribute the driving forces responsible for the northeastward progression of these processes to a thermal plume rising through the Earth’s mantle into the base of the southwest-moving North American plate. This progression began 16 million years ago (Ma) near the Nevada-Oregon border and arrived at Yellowstone about 2 Ma. Before arrival of the hotspot, an older landscape existed, particularly mountains created during the Laramide orogeny about 70–50 Ma and volcanic terrain formed by Absaroka andesitic volcanism mostly between 50–45 Ma. These landscapes were more muted than the present, hotspot-modified landscape because the Laramide-age mountains had worn down and an erosion surface of low relief had developed on the Absaroka volcanic terrain.

  15. Integration core exercises elicit greater muscle activation than isolation exercises.

    2013-03-01

    The American College of Sports Medicine and the United States Department of Health and Human Services advocate core training as a means to improve stability, reduce injury, and maintain mobility. There are countless exercises that target the primary core trunk muscles (abdominal and lumbar) with the aim of providing these benefits. However, it is unknown as to which exercises elicit the greatest activation thereby maximizing functional gains and peak performance. Thus, our purpose was to determine whether integration core exercises that require activation of the distal trunk muscles (deltoid and gluteal) elicit greater activation of primary trunk muscles in comparison with isolation core exercises that only require activation of the proximal trunk muscles. Twenty participants, 10 men and 10 women, completed 16 randomly assigned exercises (e.g., crunch, upper body extension, and hover variations). We measured muscle activity with surface electromyography of the anterior deltoid, rectus abdominus, external abdominal oblique, lumbar erector spinae, thoracic erector spinae, and gluteus maximus. Our results indicate that the activation of the abdominal and lumbar muscles was the greatest during the exercises that required deltoid and gluteal recruitment. In conclusion, when completing the core strength guidelines, an integrated routine that incorporates the activation of distal trunk musculature would be optimal in terms of maximizing strength, improving endurance, enhancing stability, reducing injury, and maintaining mobility.

    In 1985, Public Law 99-240 (Low-Level Radioactive Waste Policy Amendments Act of 1985) made the Department of Energy (DOE) responsible for the disposal of greater-than-Class C low-level radioactive waste (GTCC LLW). DOE strategies for storage and disposal of GTCC LLW required characterization of volumes, radionuclide activities, and waste forms. Data from existing literature, disposal records, and original research were used to estimate characteristics, project volumes, and determine radionuclide activities to the years 2035 and 2055. Twenty-year life extensions for 70% of the operating nuclear reactors were assumed to calculate the GTCC LLW available in 2055. The following categories of GTCC LLW were addressed: Nuclear Utilities Waste; Potential Sealed Sources GTCC LLW; DOE-Held Potential GTCC LLW; and Other Generator Waste. It was determined that the largest volume of these wastes, approximately 57%, is generated by nuclear utilities. The Other Generator Waste category contributes approximately 10% of the total GTCC LLW volume projected to the year 2035. DOE-Held Potential GTCC LLW accounts for nearly 33% of all waste projected to the year 2035. Potential Sealed Sources GTCC LLW is less than 0.2% of the total projected volume. The base case total projected volume of GTCC LLW for all categories was 3,250 cubic meters. This was substantially less than previous estimates.

    2000-07-15

    Two waves of data from a community-based study (Alameda County Study, 1994-1995) were used to investigate the association between obesity and depression. Depression was measured with 12 items covering Diagnostic and Statistical Manual of Mental Disorders: DSM-IV diagnostic criteria for major depressive episode. Following US Public Health Service criteria, obese subjects were defined as those with body mass index scores at the 85th percentile or higher. Covariates were age, sex, education, marital status, social isolation and social support, chronic medical conditions, functional impairment, life events, and financial strain. Results were mixed. In cross-sectional analyses, greater odds for depression in 1994 were observed for the obese, with and without adjustment for covariates. When obesity and depression were examined prospectively, controlling for other variables, obesity in 1994 predicted depression in 1995 (odds ratio (OR) = 1.73, 95% confidence interval (CI): 1.04, 2.87). When the data were analyzed with obesity defined as a body mass index of > or = 30, cross-sectional results were the same. However, the prospective multivariate analyses were not significant (OR = 1.43, 95% CI: 0.85, 2.43). Although these data do not resolve the role of obesity as a risk factor for depression, overall the results suggest an association between obesity and depression. The authors found no support for the "jolly fat" hypothesis (obesity reduces risk of depression). However, there has been sufficient disparity of results thus far to justify continued research.

    In 1988 a survey was carried out in order to obtain information on knowledge about reproduction, sexual activity, attitudes, and use of contraceptive methods among residents between 15 and 24 years of age in Greater Santiago. For this purpose, a multistage, self-weighted, non-replacement probability sample was chosen from the entire Santiago urban area. After 2,898 households were visited, 865 women and 800 men were selected and interviewed. For the interview, a questionnaire with 156 questions was developed; many questions were similar to those included in similar surveys in Brazil and Guatemala. The interviewers were professionals who had received prior training. Although 75% of the interviewees had attended sex education classes, they had erroneous ideas on various basic subjects. Sixty-nine percent of the women interviewed had undergone menarche before attending these classes. In addition, 35.4% of the women and 65.0% of the men had had sexual relations prior to marriage, and less than 20% had used any contraceptive method. More than 60% of the interviewees who had children had conceived them before marrying. These findings point up the necessity of offering sex education classes for children and young people, as well as facilitating their access to family planning services, in order to decrease the number of illegitimate and unwanted children that are born in Chile.

    Emergence of serogroup B meningococci of clonal complex sequence type (ST) 41/44 can cause high levels of disease, as exemplified by a recent epidemic in New Zealand. Multiplication of annual incidence rates (3.1 cases/100,000 population) of meningococcal disease in a defined German region, the city of Aachen and 3 neighboring countries (Greater Aachen) prompted us to investigate and determine the source and nature of this outbreak. Using molecular typing and geographic mapping, we analyzed 1,143 strains belonging to ST41/44 complex, isolated from persons with invasive meningococcal disease over 6 years (2001-2006) from 2 German federal states (total population 26 million) and the Netherlands. A spatially slowly moving clone with multiple-locus variable-number tandem repeat analysis type 19, ST42, and antigenic profile B:P1.7-2,4:F1-5 was responsible for the outbreak. Bactericidal activity in serum samples from the New Zealand MeNZB vaccination campaign confirmed vaccine preventability. Because this globally distributed epidemic strain spreads slowly, vaccination efforts could possibly eliminate meningococcal disease in this area.

    Knowledge of climatic variability at small spatial extents (test if climate change has increased the synchrony of surface air temperatures among 50 sites within the Greater Yellowstone Area (GYA) of the interior western United States. This important biological reserve is the largest protected area in the Lower 48 states and provides critical habitat for some of the world’s most iconic wildlife. We focused our analyses on temporal shifts and shape changes in the annual distributions of seasonal minimum and maximum air temperatures among valley-bottom and higher elevation sites from 1948–2012. We documented consistent patterns of warming since 1948 at all 50 sites, with the most pronounced changes occurring during the Winter and Summer when minimum and maximum temperature distributions increased. These shifts indicate more hot temperatures and less cold temperatures would be expected across the GYA. Though the shifting statistical distributions indicate warming, little change in the shape of the temperature distributions across sites since 1948 suggest the GYA has maintained a diverse portfolio of temperatures within a year. Spatial heterogeneity in temperatures is likely maintained by the GYA’s physiographic complexity and its large size, which encompasses multiple climate zones that respond differently to synoptic drivers. Having a diverse portfolio of temperatures may help biological reserves spread the extinction risk posed by climate change.

    The Department of Energy (DOE) has developed a plan for the management and disposal of commercially generated greater-than-Class C (GTCC) low-level radioactive waste. The Low-Level Radioactive Waste Policy Amendments Act of 1985 made DOE responsible for disposal of GTCC waste. The act requires that GTCC waste be disposed in a Nuclear Regulatory Commission (NRC)-licensed facility. The NRC has amended 10 CFR 61 to express a preference for geologic disposal of GTCC waste. Based on reassessment studies, legislative guidance, and stakeholder involvement, a revised plan has been formulated to provide for total management of GTCC waste. The plan has four major thrusts: (1) plan for GTCC waste storage at the generator site until disposal is available, (2) establish storage for GTCC sealed sources posing health and safety risk to the public, (3) facilitate storage for other GTCC waste posing health and safety risk to the public, and (4) plan for co-disposal of GTCC waste in a geologic disposal site with similar waste types. The revised plan focuses on applying available resources to near- and long-term needs.

    As earth scientists, we are drawn together by our fascination with the natural world. On alpine climbing expeditions in the Greater Ranges of Asia during 2012-14, I had the opportunity to contribute to the scientific understanding and stewardship of the places I visit for personal fulfillment. Using the "matchmaking" services of Adventurers and Scientists for Conservation, I was connected with researchers to conduct field studies in some of the world's highest and most remote mountains. Here, I present work from two projects: 1) Assessing the role of biological weathering in shaping high altitude landscapes in the Pamir Mountains of Kyrgyzstan and Tajikistan, and 2) Understanding the effects of anthropogenic biomass burning on glacial thinning in the Everest Region, Nepal. Both collaborative efforts succeeded in collecting valuable data from challenging environments using a small research budget. As a scientist with expertise in terrestrial paleoclimate and stable isotope geochemistry, these projects served to expand my research horizons and areas of professional interest. Citizen science can not only add a sense of value to otherwise selfish endeavors such as high altitude climbing, but also serve to connect scientists with the communities who appreciate their efforts most.

    Many aggregate distributions of urban activities such as city sizes reveal scaling but hardly any work exists on the properties of spatial distributions within individual cities, notwithstanding considerable knowledge about their fractal structure. We redress this here by examining scaling relationships in a world city using data on the geometric properties of individual buildings. We first summarise how power laws can be used to approximate the size distributions of buildings, in analogy to city-size distributions which have been widely studied as rank-size and lognormal distributions following Zipf [ Human Behavior and the Principle of Least Effort (Addison-Wesley, Cambridge, 1949)] and Gibrat [ Les Inégalités Économiques (Librarie du Recueil Sirey, Paris, 1931)]. We then extend this analysis to allometric relationships between buildings in terms of their different geometric size properties. We present some preliminary analysis of building heights from the Emporis database which suggests very strong scaling in world cities. The data base for Greater London is then introduced from which we extract 3.6 million buildings whose scaling properties we explore. We examine key allometric relationships between these different properties illustrating how building shape changes according to size, and we extend this analysis to the classification of buildings according to land use types. We conclude with an analysis of two-point correlation functions of building geometries which supports our non-spatial analysis of scaling.

    At 4,200 km, the Mekong River is the tenth longest river in the world. It directly and indirectly influences the lives of hundreds of millions of inhabitants in its basin. The riparian countries - Thailand, Myanmar, Cambodia, Laos, Vietnam, and a small part of China - form the Greater Mekong Subregion (GMS). This geographical region has the misfortune of being the world's epicenter of falciparum malaria, which is the most severe form of malaria caused by Plasmodium falciparum. Depending on the country, approximately 50 to 90% of all malaria cases are due to this species. In the Malaria Modeling and Surveillance Project, we have been developing techniques to enhance public health's decision capability for malaria risk assessments and controls. The main objectives are: 1) Identifying the potential breeding sites for major vector species; 2) Implementing a malaria transmission model to identify the key factors that sustain or intensify malaria transmission; and 3) Implementing a risk algorithm to predict the occurrence of malaria and its transmission intensity. The potential benefits are: 1) Increased warning time for public health organizations to respond to malaria outbreaks; 2) Optimized utilization of pesticide and chemoprophylaxis; 3) Reduced likelihood of pesticide and drug resistance; and 4) Reduced damage to environment. Environmental parameters important to malaria transmission include temperature, relative humidity, precipitation, and vegetation conditions. These parameters are extracted from NASA Earth science data sets. Hindcastings based on these environmental parameters have shown good agreement to epidemiological records.

    Full Text Available The Greater Toronto Area (GTA is one of the most multicultural communities in the world. Frequently, this description is based on ethnic, linguistic, and culinary diversity. Physical cultural diversity, such as different sports, martial arts, forms of dance, exercise systems, and other physical games and activities, remains ignored and understudied. Based on a living database of the GTA’s physical cultural diversity, this study identifies the trajectories of the lifecycle of activities that have been introduced into the GTA’s physical culture by immigrants. These pathways differ based on whether the activity is offered in a separate setting, where individuals may be participating with other immigrants of the same ethnocultural group, or mixed settings, where people are participating with people from outside of their ethnocultural group. We argue that the diversity and the lifecycle trajectories of physical cultural forms in the GTA serve as evidence of interculturalism and the contribution by immigrants to the social and cultural life of Canada.

    The US Fish and Wildlife Service (USFWS) proposed delisting the Yellowstone grizzly bear (Ursus arctos horribilis) in November 2005. Part of that process required knowledge of the most current distribution of the species. Here, we update an earlier estimate of occupied range (1990–2000) with data through 2004. We used kernel estimators to develop distribution maps of occupied habitats based on initial sightings of unduplicated females (n = 481) with cubs of the year, locations of radiomarked bears (n = 170), and spatially unique locations of conflicts, confrontations, and mortalities (n = 1,075). Although each data set was constrained by potential sampling bias, together they provided insight into areas in the Greater Yellowstone Ecosystem (GYE) currently occupied by grizzly bears. The current distribution of 37,258 km2 (1990–2004) extends beyond the distribution map generated with data from 1990–2000 (34,416 km2 ). Range expansion is particularly evident in parts of the Caribou–Targhee National Forest in Idaho and north of Spanish Peaks on the Gallatin National Forest in Montana.

    Our aim was to determine whether eating fruit and vegetables (FV) is associated with other markers of well-being beyond happiness and life satisfaction. Towards this aim, we tested whether FV consumption is associated with greater eudaemonic well-being - a state of flourishing characterized by feelings of engagement, meaning, and purpose in life. We also tested associations with two eudaemonic behaviours - curiosity and creativity. Daily diary study across 13 days (micro-longitudinal, correlational design). A sample of 405 young adults (67% women; mean age 19.9 [SD 1.6] years) completed an Internet daily diary for 13 consecutive days. Each day, participants reported on their consumption of fruit, vegetables, sweets, and chips, as well as their eudaemonic well-being, curiosity, creativity, positive affect (PA), and negative affect. Between-person associations were analysed on aggregated data. Within-person associations were analysed using multilevel models controlling for weekday and weekend patterns. Fruit and vegetables consumption predicted greater eudaemonic well-being, curiosity, and creativity at the between- and within-person levels. Young adults who ate more FV reported higher average eudaemonic well-being, more intense feelings of curiosity, and greater creativity compared with young adults who ate less FV. On days when young adults ate more FV, they reported greater eudaemonic well-being, curiosity, and creativity compared with days when they ate less FV. FV consumption also predicted higher PA, which mostly did not account for the associations between FV and the other well-being variables. Few unhealthy foods (sweets, chips) were related to well-being except that consumption of sweets was associated with greater curiosity and PA at the within-person level. Lagged data analyses showed no carry-over effects of FV consumption onto next-day well-being (or vice versa). Although these patterns are strictly correlational, this study provides the first evidence

  11. Greater decision-making competence is associated with greater expected-value sensitivity, but not overall risk taking: An examination of concurrent validity

    Full Text Available Decision-making competence reflects individual differences in the susceptibility to decision-making errors, measured using tasks common from behavioral decision research (e.g., framing effects, under/overconfidence, following decision rules. Prior research demonstrates that those with higher decision-making competence report lower incidence of health-risking and antisocial behaviors, but there has been less focus on intermediate mechanisms that may impact real-world decisions, and, in particular, those implicated by normative models. Here we test the associations between measures of youth decision-making competence (Y-DMC and one such mechanism, the degree to which individuals make choices consistent with maximizing expected value (EV. Using a task involving hypothetical gambles, we find that greater EV sensitivity is associated with greater Y-DMC. Higher Y-DMC scores are associated with (a choosing risky options when expected value favors those options and (b avoiding risky options when expected value favors a certain option. This relationship is stronger for gambles that involved potential losses. The results suggest that Y-DMC captures decision processes consistent with standard normative evaluations of risky decisions.

    Four new cases of necrosis of the omentum secondary to torsion are reported. We review the associated signs and symptoms, which are usually those of an acute inflammatory condition in the right lower quadrant (RLQ), very similar to acute appendicitis. Because of acute abdominal pain in the RLQ, along with an uncertain diagnosis, laparoscopic surgery was performed in these cases. Laparoscopy demonstrated the existence of the omental infarction and allowed for complete treatment of the condition without the need for laparotomy.

    We present WISE All-Sky mid-infrared (IR) survey detections of 55 % (17/31) of the known QSOs at z greater than 6 from a range of surveys: the SDSS, the CFHT-LS, FIRST, Spitzer and UK1DSS. The WISE catalog thus provides a substantial increase in tiie quantity of IR data available for these sources: 17 are detected in the WISE Wl (3.4 micrometer) band, 16 in W2 (4.6 micrometers), 3 in W3 (12 micrometers) and 0 in W4 (22micrometers). This is particularly important with Spitzer in its warm-mission phase and no faint follow-up capability at wavelengths longwards of 5 micrometers until the launch of JWST. WISE thus provides a useful tool for understanding QSOs found in forthcoming large-area optical/IR sky surveys, using PanSTARRS, SkyMapper, VISTA, DES and LSST. The rest-UV properties of the WISE-detected and the WISE-non-detected samples differ: the detections have brighter i/z-band magnitudes and redder rest-UV colors. This suggests thai a more aggressive hunt for very-high-redshift QSOs, by combining WISE Wl and W2 data with red observed optical colors could be effective at least, for a subset of dusty candidate QSOs. Stacking the WISE images of the WISE-non-detected QSOs indicates that they are on average significantly fainter than the WISE-detccted examples, and are thus not narrowly missing detection in the WISE catalog. The WISE-catalog detection of three of our sample in the W3 band indicates that their mid-ID flux can be detected individually, although there is no stacked W3 detection of sources detected in Wl but not. W3. Stacking analyses of WISE data for large AGN samples will be a useful tool, and high-redshifl. QSOs of all types will be easy targets for JWST.

  14. Deviance and resistance: Malaria elimination in the greater Mekong subregion.

    2016-02-01

    Malaria elimination rather than control is increasingly globally endorsed, requiring new approaches wherein success is not measured by timely treatment of presenting cases but eradicating all presence of infection. This shift has gained urgency as resistance to artemisinin-combination therapies spreads in the Greater Mekong Sub-region (GMS) posing a threat to global health security. In the GMS, endemic malaria persists in forested border areas and elimination will require calibrated approaches to remove remaining pockets of residual infection. A new public health strategy called 'positive deviance' is being used to improve health promotion and community outreach in some of these zones. However, outbreaks sparked by alternative understandings of appropriate behaviour expose the unpredictable nature of 'border malaria' and difficulties eradication faces. Using a recent spike in infections allegedly linked to luxury timber trade in Thai borderlands, this article suggests that opportunities for market engagement can cause people to see 'deviance' as a means to material advancement in ways that increase disease vulnerability. A malaria outbreak in Ubon Ratchathani was investigated during two-week field-visit in November 2014 as part of longer project researching border malaria in Thai provinces. Qualitative data were collected in four villages in Ubon's three most-affected districts. Discussions with villagers focused primarily on changing livelihoods, experience with malaria, and rosewood cutting. Informants included ten men and two women who had recently overnighted in the nearby forest. Data from health officials and villagers are used to frame Ubon's rise in malaria transmission within moral and behavioural responses to expanding commodity supply-chains. The article argues that elimination strategies in the GMS must contend with volatile outbreaks among border populations wherein 'infectiousness' and 'resistance' are not simply pathogen characteristics but also

  15. Reserves in western basins: Part 1, Greater Green River basin

    Energy Technology Data Exchange (ETDEWEB)

    1993-10-01

    This study characterizes an extremely large gas resource located in low permeability, overpressured sandstone reservoirs located below 8,000 feet drill depth in the Greater Green River basin, Wyoming. Total in place resource is estimated at 1,968 Tcf. Via application of geologic, engineering and economic criteria, the portion of this resource potentially recoverable as reserves is estimated. Those volumes estimated include probable, possible and potential categories and total 33 Tcf as a mean estimate of recoverable gas for all plays considered in the basin. Five plays (formations) were included in this study and each was separately analyzed in terms of its overpressured, tight gas resource, established productive characteristics and future reserves potential based on a constant $2/Mcf wellhead gas price scenario. A scheme has been developed to break the overall resource estimate down into components that can be considered as differing technical and economic challenges that must be overcome in order to exploit such resources: in other words, to convert those resources to economically recoverable reserves. Total recoverable reserves estimates of 33 Tcf do not include the existing production from overpressured tight reservoirs in the basin. These have estimated ultimate recovery of approximately 1.6 Tcf, or a per well average recovery of 2.3 Bcf. Due to the fact that considerable pay thicknesses can be present, wells can be economic despite limited drainage areas. It is typical for significant bypassed gas to be present at inter-well locations because drainage areas are commonly less than regulatory well spacing requirements.

    Full Text Available Echolocating greater horseshoe bats (Rhinolophus ferrumequinum emit their biosonar pulses nasally, through nostrils surrounded by fleshy appendages ('noseleaves' that diffract the outgoing ultrasonic waves. Movements of one noseleaf part, the lancet, were measured in live bats using two synchronized high speed video cameras with 3D stereo reconstruction, and synchronized with pulse emissions recorded by an ultrasonic microphone. During individual broadcasts, the lancet briefly flicks forward (flexion and is then restored to its original position. This forward motion lasts tens of milliseconds and increases the curvature of the affected noseleaf surfaces. Approximately 90% of the maximum displacements occurred within the duration of individual pulses, with 70% occurring towards the end. Similar lancet motions were not observed between individual pulses in a sequence of broadcasts. Velocities of the lancet motion were too small to induce Doppler shifts of a biologically-meaningful magnitude, but the maximum displacements were significant in comparison with the overall size of the lancet and the ultrasonic wavelengths. Three finite element models were made from micro-CT scans of the noseleaf post mortem to investigate the acoustic effects of lancet displacement. The broadcast beam shapes were found to be altered substantially by the observed small lancet movements. These findings demonstrate that-in addition to the previously described motions of the anterior leaf and the pinna-horseshoe bat biosonar has a third degree of freedom for fast changes that can happen on the time scale of the emitted pulses or the returning echoes and could provide a dynamic mechanism for the encoding of sensory information.

    Grizzly bears (Ursus arctos) in the Greater Yellowstone Ecosystem (GYE) are opportunistic omnivores that eat a great diversity of plant and animal species. Changes in climate may affect regional vegetation, hydrology, insects, and fire regimes, likely influencing the abundance, range, and elevational distribution of the plants and animals consumed by GYE grizzly bears. Determining the dietary breadth of grizzly bears is important to document future changes in food resources and how those changes may affect the nutritional ecology of grizzlies. However, no synthesis exists of all foods consumed by grizzly bears in the GYE. We conducted a review of available literature and compiled a list of species consumed by grizzly bears in the GYE. We documented >266 species within 200 genera from 4 kingdoms, including 175 plant, 37 invertebrate, 34 mammal, 7 fungi, 7 bird, 4 fish, 1 amphibian, and 1 algae species as well as 1 soil type consumed by grizzly bears. The average energy values of the ungulates (6.8 kcal/g), trout (Oncorhynchus spp., 6.1 kcal/g), and small mammals (4.5 kcal/g) eaten by grizzlies were higher than those of the plants (3.0 kcal/g) and invertebrates (2.7 kcal/g) they consumed. The most frequently detected diet items were graminoids, ants (Formicidae), whitebark pine seeds (Pinus albicaulis), clover (Trifolium spp.), and dandelion (Taraxacum spp.). The most consistently used foods on a temporal basis were graminoids, ants, whitebark pine seeds, clover, elk (Cervus elaphus), thistle (Cirsium spp.), and horsetail (Equisetum spp.). Historically, garbage was a significant diet item for grizzlies until refuse dumps were closed. Use of forbs increased after garbage was no longer readily available. The list of foods we compiled will help managers of grizzly bears and their habitat document future changes in grizzly bear food habits and how bears respond to changing food resources.

    Objective: Greater trochanter pain syndrome (GTPS) is a diverse clinical entity caused by a variety of underlying conditions. We sought to explore the impact of (1) hip morphology, namely the center-edge angle (CEa) and femoral neck-shaft (NSa) angle, (2) hip abductor tendon degeneration, (3) the dimensions of peritrochanteric edema and (4) bursitis, on the presence of GTPS, using MR imaging. Materials and methods: The presence of pain was prospectively assessed blindly by the senior author. CEa and NSa were blindly measured in 174 hip MR examinations, after completion of the clinical evaluation by another evaluator. The existence and dimensions of T2 hyperintensity of the peritrochanteric soft tissues, the existence and dimensions of bursae, as well as degeneration and tearing of gluteus tendons were also recorded. Results: Out of 174 examinations, 91 displayed peritrochanteric edema (group A) and 34 bursitis, all with peritrochanteric edema (group B). A number of 78 patients from both A and B groups, showed gluteus medius tendon degeneration and one tendon tear. CEa of groups A and B were 6° higher than those of normals (group C, P = 0.0038). The mean age of normals was 16.6 years less than in group A and 19.8 years less than in group B (P < 0.0001). Bursitis was associated with pain with a negative predictive value of 97% (P = 0.0003). Conclusion: Acetabular morphology is associated with GTPS and the absence of bursitis was proved to be clinically relevant. Peritrochanteric edema alone was not associated with local pain.

    Greater Roadrunners (Geococcyx californianus) are common, poorly studied birds of arid and semi-arid ecosystems in the southwestern United States. Conservation of this avian predator requires a detailed understanding of their movements and spatial requirements that is currently lacking. From 2006 to 2009, we quantified home-range and core area sizes and overlap, habitat selection, and survival of roadrunners (N= 14 males and 20 females) in north-central Texas using radio-telemetry and fixed kernel estimators. Median home-range and core-area sizes were 90.4 ha and 19.2 ha for males and 80.1 ha and 16.7 ha for females, respectively. The size of home range and core areas did not differ significantly by either sex or season. Our home range estimates were twice as large (x??= 108.9 ha) as earlier published estimates based on visual observations (x??= 28-50 ha). Mean percent overlap was 38.4% for home ranges and 13.7% for core areas. Male roadrunners preferred mesquite woodland and mesquite savanna cover types, and avoided the grass-forb cover type. Female roadrunners preferred mesquite savanna and riparian woodland cover types, and avoided grass-forb habitat. Kaplan-Meier annual survival probabilities for females (0.452 ?? 0.118[SE]) were twice that estimated for males (0.210 ?? 0.108), but this difference was not significant. Mortality rates of male roadrunners were higher than those of females during the spring when males call from elevated perches, court females, and chase competing males. Current land use practices that target woody-shrub removal to enhance livestock forage production could be detrimental to roadrunner populations by reducing availability of mesquite woodland and mesquite savanna habitat required for nesting and roosting and increasing the amount of grass-forb habitat that roadrunners avoid. ??2011 The Authors.
