Childhood Sexual and Physical Abuse and Adult Vulnerability to PTSD: The Mediating Effects of Attachment and Dissociation

ABSTRACT Two hundred and eighty-four adults from the metropolitan New York area reported on their history of childhood sexual abuse (CSA), childhood physical abuse (CPA), and on the nature of their exposure to the terrorist attack on the World Trade Center. The respondents also completed the Impact of Events Scale–Revised (IES–R), the Attachment Style Questionnaire (ASQ) and the Dissociative Experiences Scale (DES). Those reporting histories of CSA and/or CPA were found to endorse more serious symptoms of PTSD, as did those who witnessed the terrorist attack live. The presence of secure attachments and dissociative symptoms were related significantly to both CSA and CPA, and to scores on the IES–R. Adult attachment and dissociation were found to mediate the relationship between childhood abuse and severity of PTSD.
Exposure of the U.S. population to lead, 1991-1994.

Blood lead measurements were obtained on 13,642 persons aged 1 year and older who participated in Phase 2 of the Third National Health and Nutrition Examination Survey (NHANES III) from 1991 through 1994. NHANES III is a national representative survey of the civilian, noninstitutionalized U.S. population. The overall mean blood lead level for the U.S. population aged 1 year and older was 2.3 microgram/dl, with 2.2% of the population having levels >=10 microgram/dl, the level of health concern for children. Among U.S. children aged 1-5 years, the mean blood lead level was 2.7 microgram/dl, and 890,000 of these children (4.4%) had elevated blood lead levels. Sociodemographic factors associated with higher blood lead levels in children were non-Hispanic black race/ethnicity, low income, and residence in older housing. The prevalence of elevated blood lead levels was 21.9% among non-Hispanic black children living in homes built before 1946 and 16.4% among children in low-income families who lived in homes built before 1946. Blood lead levels continue to decline in the U.S. population, but 890,000 children still have elevated levels. Public health efforts have been successful in removing lead from population-wide sources such as gasoline and lead-soldered food and drink cans, but new efforts must address the difficult problem of leaded paint, especially in older houses, as well as lead in dust and soil. Lead poisoning prevention programs should target high-risk persons, such as children who live in old homes, children of minority groups, and children living in families with low income.

Impact of virtualness and task interdependence on extra‐role performance in software development teams

Purpose – The purpose of this paper is to understand the impact of virtualness on extra‐role performance within software development teams and the moderating effect of task interdependence on this relationship.Design/methodology/approach – Data were collected from 192 software professionals from 33 software development teams. Teams were taken as the unit of analysis. Extra‐role performance was measured using organizational citizenship behavior (OCB) scale and task interdependence within the team was measured by interdependence scale developed by Pearce and Gregersen. Virtualness was measured using an objective measure developed by the authors. Regression was used to study the moderation and main effects.Findings – Virtualness negatively influenced overall extra‐role performance within the team. In terms of individual dimensions, virtualness had a negative influence on extra‐role performances directed towards team as an entity (civic virtue and generalized compliance) but it had no impact over extra‐role p.
Navigation in an autonomous flying robot by using a biologically inspired visual odometer

While mobile robots and walking insects can use proprioceptive information (specialized receptors in the insects' leg, or wheel encoders in robots) to estimate distance traveled, flying agents have to rely mainly on visual cues. Experiments with bees provide evidence that flying insects might be using optical flow induced by egomotion to estimate distance traveled. Recently some details of this odometer have been unraveled. In this study, we propose a biologically inspired model of the bee's visual odometer based on Elementary Motion Detectors (EMDs), and present results from goal-directed navigation experiments with an autonomous flying robot platform that we developed specifically for this purpose. The robot is equipped with a panoramic vision system, which is used to provide input to the EMDs of the left and right visual fields. The outputs of the EMDs are in later stage spatially integrated by wide field motion detectors, and their accumulated response is directly used for the odometer. In a set of initial experiments, the robot moves through a corridor on a fixed route, and the outputs of EMDs, the odometer, are recorded. The results show that the proposed model can be used to provide an estimate of the distance traveled, but the performance depends on the route the robot follows, something which is biologically plausible since natural insects tend to adopt a fixed route during foraging. Given these results, we assumed that the optomotor response plays an important role in the context of goal-directed navigation, and we conducted experiments with an autonomous freely flying robot. The experiments demonstrate that this computationally cheap mechanism can be successfully employed in natural indoor environments.
3D human face recognition using point signature

We present a novel face recognition algorithm based on the point signature-a representation for free-form surfaces. We treat the face recognition problem as a non-rigid object recognition problem. The rigid parts of the face of one person are extracted after registering the range data sets of faces having different facial expressions. These rigid parts are used to create a model library for efficient indexing. For a test face, models are indexed from the library and the most appropriate models are ranked according to their similarity with the test face. Verification of each model face can be quickly and efficiently identified. Experimental results with range data involving six human subjects, each with four different facial expressions, have demonstrated the validity and effectiveness of our algorithm.
Getting the Picture: Effects of Sketch Plans and Photographs on Children's, Adolescents' and Adults' Eyewitness Recall

Summary We compared the effects of three types of visual aid on free recall across three age groups in an eyewitness paradigm. Child, adolescent and adult participants (N = 144) viewed a short film depicting a non-violent crime and, following a brief delay, gave a free-recall account. Participants then described the event once again, with the aid of their own sketch plan, a provided sketch plan or photograph, or with no visual aid. Interviews were transcribed verbatim and coded for the type and accuracy of information reported. Across all age groups, relative to the control condition, all three visual aids increased the amount of new information reported during the second free-recall account and helped participants to maintain accuracy. All three visual aids therefore had a positive effect on participants' performance; in a forensic setting, however, witnesses' own sketch plans are likely to be the safest, most easily applied and most time effective.Copyright © 2015 John Wiley & Sons, Ltd.
Assessing Relative Risks of Infection and Rejection: A Meta-analysis using an Immune Function Assay

Background. Long-term use of immunosuppressants is associated with significant morbidity and mortality in transplant recipients. A simple whole blood assay that has U.S. Food and Drug Administration clearance directly assesses the net state of immune function of allograft recipients for better individualization of therapy. A meta-analysis of 504 solid organ transplant recipients (heart, kidney, kidney-pancreas, liver and small bowel) from 10 U.S. centers was performed using the Cylex ImmuKnow assay. Methods. Blood samples were taken from recipients at various times posttransplant and compared with clinical course (stable, rejection, infection). In this analysis, 39 biopsy-proven cellular rejections and 66 diagnosed infections occurred. Odds ratios of infection or rejection were calculated based on measured immune response values. Results. A recipient with an immune response value of 25 ng/ml adenosine triphosphate (ATP) was 12 times (95% confidence of 4 to 36) more likely to develop an infection than a recipient with a stronger immune response. Similarly, a recipient with an immune response of 700 ng/ml ATP was 30 times (95% confidence of 8 to 112) more likely to develop a cellular rejection than a recipient with a lower immune response value. Of note is the intersection of odds ratio curves for infection and rejection in the moderate immune response zone (280 ng/ml ATP). This intersection of risk curves provides an immunological target of immune function for solid organ recipients. Conclusion. These data show that the Cylex ImmuKnow assay has a high negative predictive value and provides a target immunological response zone for minimizing risk and managing patients to stability.
Emerging Language Spaces Learned From Massively Multilingual Corpora

Translations capture important information about languages that can be used as implicit supervision in learning linguistic properties and semantic representations. In an information-centric view, translated texts may be considered as semantic mirrors of the original text and the significant variations that we can observe across various languages can be used to disambiguate a given expression using the linguistic signal that is grounded in translation. Parallel corpora consisting of massive amounts of human translations with a large linguistic variation can be applied to increase abstractions and we propose the use of highly multilingual machine translation models to find language-independent meaning representations. Our initial experiments show that neural machine translation models can indeed learn in such a setup and we can show that the learning algorithm picks up information about the relation between languages in order to optimize transfer leaning with shared parameters. The model creates a continuous language space that represents relationships in terms of geometric distances, which we can visualize to illustrate how languages cluster according to language families and groups. Does this open the door for new ideas of data-driven language typology with promising models and techniques in empirical cross-linguistic research?
Big data integration shows Australian bush-fire frequency is increasing significantly

Increasing Australian bush-fire frequencies over the last decade has indicated a major climatic change in coming future. Understanding such climatic change for Australian bush-fire is limited and there is an urgent need of scientific research, which is capable enough to contribute to Australian society. Frequency of bush-fire carries information on spatial, temporal and climatic aspects of bush-fire events and provides contextual information to model various climate data for accurately predicting future bush-fire hot spots. In this study, we develop an ensemble method based on a two-layered machine learning model to establish relationship between fire incidence and climatic data. In a 336 week data trial, we demonstrate that the model provides highly accurate bush-fire incidence hot-spot estimation (91% global accuracy) from the weekly climatic surfaces. Our analysis also indicates that Australian weekly bush-fire frequencies increased by 40% over the last 5 years, particularly during summer months, implicating a serious climatic shift.
Clients’ satisfaction with primary health care in Tehran: A cross-sectional study on Iranian Health Centers

BACKGROUND: Primary health care system is the basic core of public service provision in Iran. This study aimed to assess clients’ satisfaction with primary health care in Tehran, the capital of Iran, as a metropolitan. METHODS: Through a cross-sectional study in 2009-10, four urban primary health care clinics were selected through stratified random sampling. Four hundred participants were interviewed in the selected clinics about their satisfaction with the primary health care services and setting. Six domains of satisfaction including accessibility to services, continuity of care, humaneness of staff, comprehensiveness of care, provision of health education and effectiveness of services were calculated from selected variables. The descriptive statistics, chi-square and t-tests were used when appropriate. RESULTS: The mean age of users of health services was 31.3 years (SD=9.6). Thirteen percent of participants were male. The most common reasons for asking health services reported as vaccination, family planning and children care. Overall, primary health care services were suitable for eighty percent of the participants. The mean and standard deviation for Access to services was 2.11 (SD=3.44), continuity of care was -0.35 (SD=3.49), humanness of staff was 3.93 (SD=5.70), comprehensiveness of care was -0.53 (SD=3.66), provision of health educational materials was -1.45 (SD=3.64) and effectiveness of services was 4.30 (SD=7.47). CONCLUSIONS: Primary health care is a comprehensive and suitable strategy to provide health services in public health. Package of services in primary health care may affect clients’ satisfaction. Using family doctors may improve the indices.
Essays on Social Preference

This thesis consists of six essays related to experimental investigation of social preference. We investigate the effects of a pure income effect on social preference in the first essay. In the second essay we explore the effects of gender in altruism and the corresponding anticipation behavior. The third essay discusses the effects of different type of rebate schemes on altruistic behavior. We study the effects of a real and a minimal identity on initiation and escalation of conflict in the fourth essay. The fifth essay investigates the effects of social cues in (anti) social behavior. The final essay tests the effects of pure framing on altruistic behavior.
Vision based model generation for indoor environments

This paper presents our approach to retrieve a dependable three-dimensional description of a partially known indoor environment. We describe the way the sensor data from a video camera is preprocessed by contour tracing to extract the boundary lines of the objects and how this information is transformed into a three-dimensional environmental model of the world. We introduce a dynamic map that operates in a closed loop with various sensor systems improving their performance by filtering and contributing certain knowledge. The filtering relies on the capability of a mobile robot to gather sensor readings from different positions. An important part of our approach is the interaction between the dynamic map, storing and filtering the incoming information, and a module predicting missing sensor features based on structures and reference objects. This interaction helps to generate a more accurate model containing also poor detectable features, that are impossible to extract from a single sensor view.
Molecular mechanism of curcumin on the suppression of cholesterol accumulation in macrophage foam cells and atherosclerosis.

SCOPE Curcumin, a potent antioxidant extracted from Curcuma longa, confers protection against atherosclerosis, yet the detailed mechanisms are not fully understood. In this study, we examined the effect of curcumin on lipid accumulation and the underlying molecular mechanisms in macrophages and apolipoprotein E-deficient (apoE⁻/⁻) mice. METHODS AND RESULTS Treatment with curcumin markedly ameliorated oxidized low-density lipoprotein (oxLDL)-induced cholesterol accumulation in macrophages, which was due to decreased oxLDL uptake and increased cholesterol efflux. In addition, curcumin decreased the protein expression of scavenger receptor class A (SR-A) but increased that of ATP-binding cassette transporter (ABC) A1 and had no effect on the protein expression of CD36, class B receptor type I (SR-BI), or ATP-binding cassette transporter G1 (ABCG1). The downregulation of SR-A by curcumin was via ubiquitin-proteasome-calpain-mediated proteolysis. Furthermore, the curcumin-induced upregulation of ABCA1 was mainly through calmodulin-liver X receptor α (LXRα)-dependent transcriptional regulation. Curcumin administration modulated the expression of SR-A, ABCA1, ABCG1, and SR-BI in aortas and retarded atherosclerosis in apoE⁻/⁻ mice. CONCLUSION Our findings suggest that inhibition of SR-A-mediated oxLDL uptake and promotion of ABCA1-dependent cholesterol efflux are two crucial events in suppression of cholesterol accumulation by curcumin in the transformation of macrophage foam cells.
Whole Blood Transcriptome Analysis of Mycoplasma mycoides Subsp. mycoides-Infected Cattle Confirms Immunosuppression but Does Not Reflect Local Inflammation

Contagious bovine pleuropneumonia (CBPP), caused by Mycoplasma mycoides subsp. mycoides (Mmm), is a severe respiratory disease of cattle responsible for major economic losses in sub-Saharan Africa. Disease control relies mainly on the use of empirically attenuated vaccines that provide limited protection. Thus, understanding the virulence mechanisms used by Mmm as well as the role of the host immune system in disease development, persistence, and control is a prerequisite for the development of new, rationally designed control strategies. The aim of this study was to assess the use of whole blood transcriptome analysis to study cattle-Mmm interactions, starting by the characterization of the bovine response to Mmm infection during the acute form of the disease. For that purpose, we compared the transcriptome profile of whole blood from six cattle, before challenge by contact with Mmm-infected animals and at the appearance of first clinical signs, using a bovine microarray. Functional analysis revealed that 680 annotated genes were differentially expressed, with an overwhelming majority of down-regulated genes characterizing an immunosuppression. The main bio-functions affected were “organismal survival”, “cellular development, morphology and functions” and “cell-to cell signaling and interactions”. These affected functions were consistent with the results of previous in vitro immunological studies. However, microarray and qPCR validation results did not highlight pro-inflammatory molecules (such as TNFα, TLR2, IL-12B and IL-6), whereas inflammation is one of the most characteristic traits of acute CBPP. This global gene expression pattern may be considered as the result, in blood, of the local pulmonary response and the systemic events occurring during acute CBPP. Nevertheless, to understand the immune events occurring during disease, detailed analyses on the different immune cell subpopulations, either in vivo, at the local site, or in vitro, will be required. Whole blood transcriptome analysis remains an interesting approach for the identification of bio-signatures correlating to recovery and protection, which should facilitate the evaluation and validation of novel vaccine formulations.
Parenting Styles and Practices of Latino Parents and Latino Fifth Graders’ Academic, Cognitive, Social, and Behavioral Outcomes

A vast literature documents a host of advantages conferred upon middle class European American children whose parents employ an authoritative style of parenting, including enhanced academic achievement and positive behavioral outcomes. The literature is much less clear about the relationship between parental authority style and child outcomes in other cultural contexts. In this study, we examined the relations among authoritative, authoritarian, and permissive parenting styles and practices and several academic and behavioral outcomes among fifth grade Latino/a students. We found significant positive relations between parental authoritativeness and grades, academic engagement, social competence, self-regulation, and perspective-taking as well as negative relations between authoritativeness and aggression. We found no relations between authoritarian or permissive parenting styles and child outcomes. We consider these findings in light of what other researchers have posited about collectivist parenting styles and practices.
“That’s Just How It Is”

In this mixed-methods study, we adopted a feminist theoretical lens in conceptualizing gender as hierarchical and complementary ideologies—femininity and masculinity—that are fundamental constituents of institutionalized heterosexuality as a way to understand the persistence of gender inequity in adolescents’ heterosexual relationships. In Study 1, we conducted separate analyses for girls and boys to evaluate whether masculinity ideology for boys and femininity ideology for girls account for boys’ endorsement of male coercion and for girls’ endorsement of feminine conventions in heterosexual relationships with a sample of 250 tenth-grade students (n = 144 girls). Masculinity ideology proved to be as strong or stronger than femininity ideology in predicting these respective outcomes. In Study 2, we sought to understand this pattern through a thematically informed narrative analysis of interviews with 53 of the Study 1 participants (n = 35 girls) on their beliefs about and experiences with sexual expression and heterosexual relationships. Girls described the dual task of managing boys’ masculinity as well as their own femininity. Boys, by contrast, described girls’ femininity in instrumental terms for the management of their own masculinity. Integration of these results provides greater insight into how institutionalized heterosexuality is reproduced through the functioning of these hierarchical complementary gender ideologies.
Music during after-death care: a focus group study.

BACKGROUND The intensive care unit (ICU) is not only a place to recover from injuries incurred during accidents and from serious illness. For many patients, it is also a place where they might die. Nursing care does not stop when a patient dies; rather, it continues with the care of the deceased and with family support. The aims of this study were (1) to explore the experiences and attitudes of nurses towards the use of ambient music in the ICU during after-death care and (2) to describe the feedback nurses received from relatives when music was used during the viewing. METHOD A qualitative design employing focus group interviews was used. Three focus group interviews with 15 nurses were conducted. All the interviews were audiotaped, transcribed verbatim and analysed using qualitative content analysis. FINDINGS Six main categories of attitudes emerged from the analysis: (1) different attitudes among nurses towards the use of music; (2) music affects the atmosphere; (3) music affects emotions; (4) use of music was situational; (5) special choice of music and (6) positive feedback from the bereaved. CONCLUSION This study demonstrates that music might be helpful for nurses during after-death care as well as for the care of the relatives. RELEVANCE TO CLINICAL PRACTICE Including ambient music in an after-death care programme can help nurses show respect for the deceased as the body is being prepared. Music played during the viewing may be a way of helping relatives in their time of grieving. It may ease the situation by making that event special and memorable. However, standardizing this intervention does not seem appropriate. Rather, the individual nurse and the family must decide whether music is to be used in a particular situation.
