An assessment of faculty and dental student decision-making in ethics.
Behar-Horenstein, Linda S; Catalanotto, Frank A; Garvan, Cynthia Wilson; Hudson-Vassell, Charisse
2014-01-01
This study reports and compares dental student and dental faculty scores to national norms for the Defining Issues Test 2, a measure of ethical decision-making competency. The findings showed that dental students and faculty tend to make decisions that promote self-interest, paralleling the ethical orientation of business professionals. Differences associated with gender, language, and norms from previous studies were observed. The findings underscore the importance of raising dental faculty and student awareness of their own ethical decision-making approaches. More importantly, the findings highlight the need to ensure that dental faculty have both the knowledge and skills to train dental students about the central role that ethical decision-making must play in patient care.
A Comparative Analysis of the ADOS-G and ADOS-2 Algorithms: Preliminary Findings.
Dorlack, Taylor P; Myers, Orrin B; Kodituwakku, Piyadasa W
2018-06-01
The Autism Diagnostic Observation Schedule (ADOS) is a widely utilized observational assessment tool for diagnosis of autism spectrum disorders. The original ADOS was succeeded by the ADOS-G with noted improvements. More recently, the ADOS-2 was introduced to further increase its diagnostic accuracy. Studies examining the validity of the ADOS have produced mixed findings, and pooled relationship trends between the algorithm versions are yet to be analyzed. The current review seeks to compare the relative merits of the ADOS-G and ADOS-2 algorithms, Modules 1-3. Eight studies met inclusion criteria for the review, and six were selected for paired comparisons of the sensitivity and specificity of the ADOS. Results indicate several contradictory findings, underscoring the importance of further study.

{sup 17}O Knight shift measurements in Sr{sub 2}RuO{sub 4} were performed over the wide range of magnetic field 3.2--11.4kOe parallel to the basal RuO{sub 2} planes. The spin susceptibility is totally unchanged through its T{prime}{sub c}, evidencing that the spin-triplet superconducting state is realized in Sr{sub 2}RuO{sub 4}. The results indicates that the Cooper pairs consist of the parallel spin pairs {vert{underscore}bar}{up{underscore}arrow}{up{underscore}arrow}> and {vert{underscore}bar}{down{underscore}arrow}{down{underscore}arrow}> with their quantization axis perpendicular to the c-axis direction. The in-plane 2D nearly ferromagnetic spin fluctuations may play a role for the stabilization of this state among various representations of spin-triplet order parameter.

Recent scholarship has focused on the role that cross-border social and economic ties play in shaping health outcomes for migrant populations. Nevertheless, the extant empirical work on this topic has paid little attention to the health impacts of cross-border separation from close family members. In this paper we examine the association between cross-border ties-and cross-border separation-with the health of sub-Saharan African (SSA) migrant adults living in metropolitan France using data from the nationally representative "Trajectoire et Origines" survey (n = 1980 SSA migrants). In logistic regression analyses we find that remitting money and having a child abroad are each associated with poor health among women, but not men. The effect of remittances on health is also modified by the location of one's children: remittance sending is associated with poor health only for SSA-migrants separated from their children. These findings underscore the importance of examining both cross-border connection and cross-border separation in studies of immigrant health, and also underscore the heterogeneous relationships between cross-border ties and health for men and women. This is the first study to our knowledge that examines the relationship between cross-border ties and health for migrants in Europe, with a focus on SSA-migrants in France. These findings have important implications for the health of the growing immigrant and refugee populations in Europe and around the globe. Copyright © 2016 Elsevier Ltd. All rights reserved.
Cushioning, weathering, place, and community in rural grandmother-mothering.
Thomas, Elizabeth Ann
2011-01-01
Place influences rural women's health when distance and lack of anonymity contribute to a reluctance to seek care. A qualitative design was used to explore relationships between place and the health of rural grandmothers raising grandchildren. The study generated findings concerning theory related to perceptual experience of rurality, identifying "Cushioning," as a basic social concept and "Weathering," "Paradoxical Place," and "Community Mothering" as subconcepts. Physical and mental wear and tear, distance, isolation and unraveling community mothering undermined "Cushioning" and reflected in self-health neglect narratives. Findings underscore the importance of place to the health of rural women raising grandchildren.
Genetic and environmental origins of health anxiety: a twin study

2006-01-01
Excessive health anxiety - which is anxiety about one's health that is disproportionate to the person's medical status - is a common and often debilitating problem. Little is known about its etiology. The present study investigated the role of genetic and environmental factors using a classic twin study method. Results indicated that, after controlling for medical morbidity, environmental influences accounted for most of individual differences in health anxiety. These findings underscore the importance of psychosocial interventions, which have been shown to be among the most effective interventions for excessive health anxiety. PMID:16757996

Price responsiveness of demand for cigarettes: does rationality matter?
Laporte, Audrey
2006-01-01
Meta-analysis is applied to aggregate-level studies that model the demand for cigarettes using static, myopic, or rational addiction frameworks in an attempt to synthesize key findings in the literature and to identify determinants of the variation in reported price elasticity estimates across studies. The results suggest that the rational addiction framework produces statistically similar estimates to the static framework but that studies that use the myopic framework tend to report more elastic price effects. Studies that applied panel data techniques or controlled for cross-border smuggling reported more elastic price elasticity estimates, whereas the use of instrumental variable techniques and time trends or time dummy variables produced less elastic estimates. The finding that myopic models produce different estimates than either of the other two model frameworks underscores that careful attention must be given to time series properties of the data.
Latino adolescents' academic success: the role of discrimination, academic motivation, and gender.
Alfaro, Edna C; Umaña-Taylor, Adriana J; Gonzales-Backen, Melinda A; Bámaca, Mayra Y; Zeiders, Katharine H
2009-08-01
Guided by the academic resilience perspective, the current longitudinal study examined whether academic motivation mediated the relation between Latino adolescents' (N=221) experiences with discrimination and their academic success. The potential moderating role of gender was also examined. Using multiple group analysis in structural equation modeling, findings indicated that perceived discrimination at Wave 2 significantly predicted academic motivation at Waves 2 and 3 for boys but not girls. Additionally, for boys, academic motivation significantly mediated the relation between perceived discrimination and academic success. Findings underscore the importance of considering the long-term implications of discrimination for Latino boys' academic success. Furthermore, findings encourage moving beyond the examination of gender differences in specific academic outcomes (e.g., academic success) and focusing on how the processes leading to academic success vary by gender.

The human immunodeficiency virus (HIV-1) protein Tat has been implicated in mediating neuronal apoptosis, one of the hallmark features of HIV-associated dementia (HAD). Mitigation of the toxic effects of Tat could thus be a potential mechanism for reducing HIV toxicity in the brain. In this study we demonstrated that Tat-induced neurotoxicity was abolished by NMDA antagonist-MK801, suggesting the role of glutamate in this process. Furthermore, we also found that pretreatment of SH-SY5Y cells with PDGF exerted protection against Tat toxicity by decreasing extracellular glutamate levels. We also demonstrated that extracellular calcium chelator EGTA was able to abolish PDGF-mediated neuroprotection, therebymore » underscoring the role of calcium signaling in PDGF-mediated neuroprotection. We also showed that Erk signaling pathway was critical for PDGF-mediated protection of cells. Additionally, blocking calcium entry with EGTA resulted in suppression of PDGF-induced Erk activation. These findings thus underscore the role of PDGF-mediated calcium signaling and Erk phosphorylation in the protection of cells against HIV Tat toxicity.« less

2015-01-01
This longitudinal study assessed the role of early sleep patterns in predicting attention regulation and behavior problems. Sleep of 43 infants was assessed using actigraphy at 12 months of age and then reassessed when the children were 3-4 years old. During this follow-up, their attention regulation and behavior problems were also assessed using a computerized test and parental reports. Lower quality of sleep in infancy significantly predicted compromised attention regulation and behavior problems. These findings underscore the need to identify and treat early sleep problems.

This study examined differences in behavioral autonomy age expectations between Mexican-origin mothers and their adolescent daughters (N = 319 dyads); variability in behavioral autonomy age expectations as a function of nativity and maternal educational attainment also was examined. Findings indicated significant differences between mothers and daughters such that mothers reported later expectations for the timing of behavioral autonomy than did daughters. Follow-up analyses indicated that findings appeared to be driven by maternal nativity, with dyads comprised of Mexico-born mothers reporting the latest age expectations for behavioral autonomy when compared with dyads comprised of U.S.-born mothers. Findings underscore the need to examine normative development among Latino adolescents and their families with a specific focus on how sociocultural characteristics can contribute to within-family differences.

Sometimes, clinicians assume caregivers in cultural groups believed to have large social networks and strong social support need little intervention from health professionals. This longitudinal study tests five hypotheses about the social relationships of Mexican American compared to non-Hispanic White caregivers and whether negative changes in social support affect perceived health. The sample includes 66 Mexican American and 92 non-Hispanic White caregivers. Findings show that social networks and social support are similar at baseline and similarly stable for 1 year. Negative changes in social support are correlated with poorer health perceptions. Findings underscore the importance of designing interventions that are culturally competent based on what the caregiver is experiencing rather than cultural stereotypes.
Recent Advances in Tourette Syndrome
Bloch, Michael; State, Matthew; Pittenger, Christopher
2014-01-01
Purpose of review The purpose of this review is to consider the recent literature pertaining to the neurobiology, genetics and treatment of Tourette syndrome (TS). Recent findings Over the last several years, both neuropathological and genetic findings have further focused attention on long-standing hypotheses regarding the role of the basal ganglia in the etiology of tics and TS. Moreover, while the field awaits the results the first large-scale genetic studies, recent findings have already mirrored developments in the neuropsychiatric genetics literature more broadly, highlighting the value of the study of rare variation and the overlap of risks among seemingly disparate diagnostic categories. Finally, treatment studies have underscored the importance of cognitive-behavioral as well as pharmacological interventions for the treatment of tic disorders. Summary Recent findings have led to novel, testable hypotheses regarding the molecular and cellular mechanisms underlying TS. These, in turn, have begun to provide new avenues to conceptualizing treatment strategies. While the development of additional medication options is a pressing need, recent data has demonstrated both the safety and efficacy of non-pharmacological approaches. PMID:21386676
Changes in Substance Use Symptoms Across Adolescence in Youth Perinatally Infected with HIV
Elkington, K. S.; Bauermeister, J. A.; Bucek, A.; Dolezal, C.; Leu, C. S.; Mellins, C. A.
2016-01-01
The paper utilizes data collected at three time points in a longitudinal study of perinatally HIV-infected (PHIV+) and a comparison group of perinatally exposed but HIV-uninfected (PHEU) youths in the United States (N = 325). Using growth curve modeling, the paper examines changes in substance use symptoms among PHIV+ and PHEU youths as they transition through adolescence, and assesses the individual and contextual factors associated with the rate of change in substance use symptoms. Findings indicate that substance use symptoms increased over time among PHIV+ youths, but not among PHEU youths. The rate of change in these symptoms was positively associated with an increasing number of negative life events. Study findings underscore the need for early, targeted interventions for PHIV+ youths, and interventions to reduce adversities and their deleterious effects in vulnerable populations. PMID:27371136

2016-01-01
The aim of this study was to describe the context and impact of caregiving for grandchildren with health concerns on grandparents. The study sample comprised 391 African American grandparents aged 55 or older. Logistic regression analysis indicated that grandparent caregivers of grandchildren with psychiatric or behavioral problems were more likely to experience a negative impact on their health (AOR = 7.86, p = .008) and leisure (AOR = 14.31, p = .024) than grandparent caregivers of grandchildren with no or other types of health problems. The findings underscore the need to support African American grandparent caregivers, particularly those raising grandchildren with mental health problems. PMID:27805833
Predictors of Prosocial Behavior among Chinese High School Students in Hong Kong
Siu, Andrew M. H.; Shek, Daniel T. L.; Lai, Frank H. Y.
2012-01-01
This study examined the correlates and predictors of prosocial behavior among Chinese adolescents in Hong Kong. A sample of 518 high school students responded to a questionnaire containing measures of antisocial and prosocial behavior, prosocial norms, pragmatic values, moral reasoning, and empathy. Preliminary analyses showed that there were gender differences in some of the measures. While correlation analyses showed that parental education, prosocial norms, pragmatic values, moral reasoning, and empathy were related to prosocial behavior, regression analyses showed that prosocial norms, pragmatic values, and empathy dimensions (personal distress and empathy) were key predictors of it. The findings are largely consistent with theoretical predictions and previous research findings, other than the negative relationship between personal distress and prosocial behavior. The study also underscores the importance of values and norms in predicting prosocial behavior, which has been largely neglected in previous studies. PMID:22919326
Is anybody listening? A phenomenological study of pain in hospitalized persons with AIDS.
Newshan, G
1998-01-01
Pain is a common problem among hospitalized persons with AIDS (PWAs), yet it has not been well studied. The purpose of this study was to understand, using the phenomenological method, the experience of pain in hospitalized PWAs. Multiple sources of data, including interviews with 11 hospitalized PWAs, literature, poetry, and film, were used to investigate the phenomenon. Five broad themes emerged: knowing pain, battling pain, having AIDS, pain's influence, and being a drug user. Multiple barriers to effective pain management were identified. Although there were commonalities in the experience of pain in chemically dependent and nonchemically dependent PWAs, unique challenges for the chemically dependent PWAs were identified. The findings indicate the importance of listening to and believing reports of pain. In addition, the findings underscore the delicate balance that exists between pain relief and relapse in PWAs with a history of chemical dependency.
A Population-Based Inquiry of Homeless Episode Characteristics and Early Educational Well-Being.
Fantuzzo, John; Leboeuf, Whitney; Brumley, Benjamin; Perlman, Staci
2013-06-01
Child homelessness and educational well-being is an area of national research that requires more precise investigation to address mixed findings. The aim of this study was to extend the investigation of the relations between homelessness and educational well-being by determining if timing and frequency of homeless episodes are differentially associated with children's academic and classroom engagement outcomes. This investigation used a comprehensive research model to study the effects of these homeless episode characteristics within a large urban student cohort. Additionally, this study accounted for co-occurring early risk factors. Findings indicated that having a first homeless episode in early childhood was associated with non-proficiency in mathematics and academic engagement problems. Also more frequent homeless episodes were related to truancy in third grade. These results stress the importance of early intervention for homeless children and underscore the need to further understand the variation in young children's homeless experiences.
Social support mediates the association between benefit finding and quality of life in caregivers.
Brand, Charles; Barry, Lorna; Gallagher, Stephen
2016-06-01
The psychosocial pathways underlying associations between benefit finding and quality of life are poorly understood. Here, we examined associations between benefit finding, social support, optimism and quality of life in a sample of 84 caregivers. Results revealed that quality of life was predicted by benefit finding, optimism and social support. Moreover, the association between benefit finding and quality of life was explained by social support, but not optimism; caregivers who reported greater benefit finding perceived their social support be higher and this, in turn, had a positive effect on their overall quality of life. These results underscore the importance of harnessing benefit finding to enhance caregiver quality of life. © The Author(s) 2014.

Prominences constitute the most complex magnetic structures in the solar corona. The ubiquitous presence of their seemingly confined dense and cool plasma in an otherwise million-degree environment remains a puzzle. Using a decade of white light total solar eclipse observations, we show how these images reveal an intricate relationship between prominences and coronal structures both in their immediate vicinity, known as coronal cavities, and in the extended corona out to several solar radii. Observations of suspended prominences and twisted helical structures spanning several solar radii are central to these findings. The different manifestations of the prominence-corona interface that emerge frommore » this study underscore the fundamental role played by prominences in defining and controlling the complex expansion and dynamic behavior of the solar magnetic field in the neighborhood of magnetic polarity reversal regions. This study suggests that the unraveling of prominences and the outward expansion of the helical twisted field lines linked to them could be the solar origin of twisted magnetic flux ropes detected in interplanetary space, and of the mechanism by which the Sun sheds its magnetic helicity. This work also underscores the likely role of the prominence-corona interface as a source of the slow solar wind.« less
Predictors of parenting stress in patients with haematological cancer.
Fernandes, Cheryl; Muller, Robert; Rodin, Gary
2012-01-01
This study was designed to identify potential determinants of parenting stress in parents with leukemia or lymphoma and with children younger than age 18 years. Participants recruited at a comprehensive cancer center completed self-report measures of parenting stress, attachment style, parenting alliance, depression, and anxiety. Depression was positively correlated with parenting stress. Anxious and avoidant attachment styles, but not the degree of physical distress or the quality of the parenting alliance, significantly predicted parenting stress. These findings underscore the relationship of parenting stress to psychological well-being and the contribution of individual characteristics in parents to this stress.

Some couples find in infertility the bonding opportunities that reinforce their relationship. Using an interpretative phenomenological analysis, this study examined marital benefits in three couples seeking fertility treatment. Interviews revealed five types of benefits: being engaged in a shared hardship, feeling closer to one another, feeling reassured in the relationship, developing a satisfying communication and support behaviors, and having faith in the couple's capacity to face adversity. A dyadic analysis also illustrated how marital benefits developed in each couple. Marital benefits nourished marital satisfaction, thus underscoring their importance to help couples cope through fertility treatment.

The present study investigated how volunteering was influenced by individual resources and social capital among four racial/ethnic groups of adults aged 50 and older. The data came from the California Health Interview Survey, a statewide sample that includes non-Hispanic Whites ( n = 18,927), non-Hispanic Asians ( n = 2,428), non-Hispanic Blacks ( n = 1,265), and Hispanics ( n = 3,799). Logistic regression models of volunteering were estimated to explore the effects of human and social capital within and across the racial/ethnic groups. Compared to Whites, racial/ethnic minority adults volunteered less. Although education was a significant predictor of volunteering across all groups, the findings indicated group-specific factors related to human and social capital. Results showed similarities and differences associated with volunteer participation among diverse racial/ethnic groups. The findings underscore the importance of understanding ways of creating inclusive opportunities for civic engagement among an increasingly diverse population.

This study examined differences in behavioral autonomy age expectations between Mexican-origin mothers and their adolescent daughters (N = 319 dyads); variability in behavioral autonomy age expectations as a function of nativity and maternal educational attainment also was examined. Findings indicated significant differences between mothers and daughters, such that mothers reported later expectations for the timing of behavioral autonomy than did daughters. Follow-up analyses indicated that findings appeared to be driven by maternal nativity, with dyads comprised of Mexico-born mothers reporting the latest age expectations for behavioral autonomy when compared with dyads comprised of U.S. born mothers. Findings underscore the need to examine normative development among Latino adolescents and their families with a specific focus on how sociocultural characteristics can contribute to within-family differences.

The current longitudinal study examined whether differences between Mexican-origin adolescent mothers and their mother figures (N = 204 dyads) in attitudes on the status attained through teen pregnancy were associated with conflict in their coparenting relationship and whether coparenting conflict was associated with adolescent mothers’ perceptions of social support. Findings revealed that when adolescents held more positive attitudes than their mother figures about the status gained through teen pregnancy, they tended to report greater coparenting conflict with their mother figures. Furthermore, greater coparenting conflict was significantly associated with decreases in adolescents’ perceptions of social support (i.e., emotional, instrumental, companion support) 1 year later. Findings underscore the importance of incongruent attitudes and the quality of coparenting relationships between adolescent mothers and their mother figures in relation to support processes. Findings are discussed with respect to understanding Mexican-origin adolescent mothers’ social support in the context of family subsystem attitudes and interactions. PMID:29263557

What didTriplett really find? A contemporary analysis of the first experiment in social psychology.
Strube, Michael J
2005-01-01
In 1898, Norman Triplett published was has been called the first experiment in social psychology and sports psychology. Claiming to demonstrate "the dynamogenic factors in pacemaking and competition," this oft-cited article began the serious investigation of social facilitation. This area of research now numbers in the hundreds of published works, includes the study of humans and other animials, and encompasses basic research and applied settings. But what did Triplett really find? I examine Triplett's original data and show that very little evidence existed for the social facilitation of the simple task he investigated. These analyses indicate the need to correct contemporary accounts of Triplett's work and underscore the differences in how research was evaluated at that time compared with today.

This study examined whether individuals with borderline personality disorder (BPD) would exhibit augmented emotional responses to picture stimuli after being challenged with an ideographic interpersonal conflict script. Participants were 24 adults diagnosed with BPD, 23 adults diagnosed with obsessive compulsive personality disorder (OCPD), and 28 normal controls. Participants viewed emotionally evocative pictures before and after listening to the interpersonal script while a variety of physiological measures were recorded. Findings indicated that the interpersonal script was effective in eliciting enduring emotional responses from the BPD group relative to the control groups. However, despite the effectiveness of the interpersonal challenge task, there were no group differences in emotional responding to the affect eliciting stimuli. The findings underscore the complexities involved in examining emotional dysregulation in BPD in a laboratory setting. PMID:22449065

We investigated the inclusion of a curricular module on global climate change in an Elementary Science Methods course. Using complementary research methods, we analyzed findings from 63 teacher candidates' drawings, questionnaires, and journal entries collected throughout their participation in the module. We highlighted three focal cases to illustrate the diversity of participants' experiences. Findings suggest potential positive impacts on teacher candidates' content understanding related to global climate change, confidence to teach, and awareness of resources to support their future science instruction. Recommendations for science teacher education underscore the importance of providing opportunities for teacher candidates to increase their relevant content understanding, helping teacher candidates become familiar with appropriate curricular resources, and engaging in ongoing conversation and evaluation of developing views and understandings related to global climate change.

We took an individual differences approach to explain revenge tendencies in powerholders. Across four experimental studies, chronically powerless individuals sought more revenge than chronically powerful individuals following a high power episode (Studies 1 and 2), when striking a powerful pose (Study 3), and when making a powerful hand gesture (Study 4). This relationship vanished when participants were not exposed to incidental power. A meta-analysis revealed that, relative to a lack of power or a neutral context, exposure to incidental power increased vengeance among the chronically powerless and reduced vengeance among the chronically powerful. These findings add to previous research on relations between power and aggression, and underscore the role of individual differences as a determinant of powerholders' destructive responses. © 2013 The British Psychological Society.

Researchers have consistently documented the relationship between optimism and benefit finding; however, there is a dearth of research on the psychological mechanisms mediating their association. This cross-sectional study sought to elucidate the mediating role of positive reappraisal and social support in the optimism-benefit finding relationship in parents caring for children with developmental disabilities by testing a parallel multiple mediation model. One hundred and forty-six parents caring for children with developmental disabilities completed an online survey assessing optimism, positive reappraisal, social support and benefit finding. Optimism was not directly related to benefit finding but rather influenced it indirectly through positive reappraisal and social support. Specifically, higher levels of optimism predicted greater positive reappraisal and social support, which in turn led to greater benefit finding in parents. These results underscore the importance of targeting parents' perceptions of benefits through both positive reappraisal and social support in order to help them cope with the demands of the caregiving context.

Soft tissue calcification is a pathological condition in which calcium and phosphate salts are deposited in the soft tissue organic matrix. This study presents an unusual calcification noted in the cartilaginous portion of the Eustachian tube. A 67-year-old woman presented for dental treatment, specifically for implant placement, and cone-beam computed tomography (CBCT) was performed. The CBCT scan was reviewed by a board-certified oral and maxillofacial radiologist and revealed incidental findings of 2 distinct calcifications in the cartilaginous portion of the Eustachian tube. To the authors' knowledge, no previous study has reported the diagnosis of Eustachian tube calcification using CBCT. This report describes an uncommon variant of Eustachian tube calcification, which has a significant didactic value because such cases are seldom illustrated either in textbooks or in the literature. This case once again underscores the importance of having CBCT scans evaluated by a board-certified oral and maxillofacial radiologist.
Exploring comfort food preferences across age and gender.
Wansink, Brian; Cheney, Matthew M; Chan, Nina
2003-09-01
Building on findings related to physiological and psychological motivations of food preference, this research develops a framework to examine preferences toward comfort foods. Study 1 used a North American survey of 411 people to determine favored comfort foods, and Study 2 quantified the preferences for these foods across gender and across age groups using a stratified sample of 1005 additional people. Consistent with hypotheses, the findings showed different comfort food preferences across gender and across age. Males preferred warm, hearty, meal-related comfort foods (such as steak, casseroles, and soup), while females instead preferred comfort foods that were more snack related (such as chocolate and ice cream). In addition, younger people preferred more snack-related comfort foods compared to those over 55 years of age. Associations with guilty feelings underscored how these different preferences between males and females may extend to areas of application.

The present study examined the specificity of autobiographical memory in adolescents and adults with versus without child sexual abuse (CSA) histories. Eighty-five participants, approximately half of whom per age group had experienced CSA, were tested on the Autobiographical Memory Interview. Individual difference measures, including for trauma-related psychopathology, were also administered. Findings revealed developmental differences in the relation between autobiographical memory specificity and CSA. Even with depression statistically controlled, reduced memory specificity in CSA victims relative to controls was observed among adolescents but not among adults. A higher number of Posttraumatic Stress Disorder criteria met predicted more specific childhood memories in participants who reported CSA as their most traumatic life event. These findings contribute to the scientific understanding of childhood trauma and autobiographical memory functioning and underscore the importance of considering the role of age and degree of traumatization within the study of autobiographical memory.

This research examines if and how social and cultural stereotypes insulate or aggravate the risk for adolescent victimization and partially explain racial and ethnic disparities with being a victim of violence at school. Analyses that draw on the Educational Longitudinal Study of 2002 and use multilevel analytical techniques suggest important results. Most notably, increased educational achievement, academic involvement, and having White American friendships are potential victimization risk factors for Black/African American and Latino American adolescents at urban and/or suburban schools. In addition to discussing the findings, this study underscores the importance of investigating the complexities associated with race and ethnicity when addressing adolescent victimization. © The Author(s) 2014.
Try to find me: social anxiety and peer first impressions.
Aiken, Audrey; Human, Lauren J; Alden, Lynn E; Biesanz, Jeremy C
2014-11-01
Following initial interactions, some people are less willing to pursue ongoing contact with socially anxious individuals than with those who are not socially anxious. To better understand this process, we conducted two studies that examined peers' first impressions of target individuals. Unacquainted individuals (N=104 and 114) participated in round robin, unstructured interactions in groups of 3 to 10 and then rated each partner and themselves on items reflecting the Big Five personality dimensions. The ratings were analyzed according to Biesanz's (2010) social accuracy model of interpersonal perception, which distinguishes the positivity from the accuracy of social judgments. Study 1 revealed that perceivers did not view socially anxious targets more negatively or as less likable than non-socially anxious targets but were less able to recognize their unique personality features. Study 2 replicated those findings and indicated that perceivers' difficulties recognizing socially anxious targets' unique features were not due to negative biases in the socially anxious targets' self-ratings or to general psychological maladjustment. The findings are consistent with cognitive models, which underscore the role of self-concealment in social anxiety disorder. Copyright © 2014. Published by Elsevier Ltd.

Background The psychological impact on survivors of terrorism has been well documented. However, studies on adolescent survivors and the academic performance of high school students following a terrorist attack are lacking. Objective This study investigated academic performance, absenteeism, and school support amongst survivors of a terrorist attack in Norway. Method Data from a longitudinal interview study were linked to officially registered grades of students (N=64) who successfully completed their 3-year senior high school program. Statistical tests of mean differences and linear regression were used to compare the survivors’ registered grades with the national grade point average, before and after the event, as well as to assess absenteeism, self-reported grades and to test the association with school support. Results The students’ grades were lower the year after the event than they had been the year before, and they were also lower than the national grade point average (p<0.001). However, their grades improved in the last year of high school, indicating possible recovery. Absence from school increased after the event, compared to the previous year. However, students reported high satisfaction with school support. Conclusion The results indicate that academic functioning was reduced in the year after the traumatic event, but for students who successfully completed high school, the school situation improved 2 years after the event. The findings underscore the importance of keeping trauma-exposed students in school and providing support over time. A more defined educational approach to maintaining school attendance and educational measures which compensate for learning loss are needed in trauma-sensitive teaching. Highlights of the article School functioning among high school students following a terrorist attack. The findings showed a decline in school performance and increased absence after the event. For students who successfully completed high school, high satisfaction with school support was reported and an improvement in grades could be observed over time, indicating possible recovery. The findings underscore the importance of keeping trauma-exposed students in schools and providing support over time. PMID:27171613
An Observational Study of Children's Involvement in Informed Consent for Exome Sequencing Research.

The goal of this study was to examine children's involvement in consent sessions for exome sequencing research and associations of involvement with provider and parent communication. Participants included 44 children (8-17 years) from five cohorts who were offered participation in an exome sequencing study. The consent sessions were audiotaped, transcribed, and coded. Providers attempted to facilitate the child's involvement in the majority (73%) of sessions, and most (75%) children also verbally participated. Provider facilitation was strongly associated with likelihood of child participation. These findings underscore that strategies such as asking for children's opinions and soliciting their questions show respect for children and may increase the likelihood that they are engaged and involved in decisions about research participation.

This report summarizes emerging opportunities for behavioral science to help advance the field of gene-environment and gene-behavior interactions, based on presentations at The National Cancer Institute (NCI) Workshop, "Gene-Nutrition and Gene-Physical Activity Interactions in the Etiology of Obesity." Three opportunities are highlighted: (i) designing potent behavioral "challenges" in experiments, (ii) determining viable behavioral phenotypes for genetics studies, and (iii) identifying specific measures of the environment or environmental exposures. Additional points are underscored, including the need to incorporate novel findings from neuroimaging studies regarding motivation and drive for eating and physical activity. Advances in behavioral science theory and methods can play an important role in advancing understanding of gene-brain-behavior relationships in obesity onset.

The reliability and validity of the Mental Health Statistics Improvement Program (MHSIP) Adult Consumer Survey were assessed in a statewide convenience sample of 459 persons with severe mental illness served through a public mental health system. Consistent with previous findings and the intent of its developers, three factors were identified that demonstrate good internal consistency, moderate test-retest reliability, and good convergent validity with consumer perceptions of other aspects of their care. The reliability and validity of the MHSIP Adult Consumer Survey documented in this study underscore its scientific and practical utility as an abbreviated tool for assessing access, quality and appropriateness, and outcome in mental health service systems.
Childhood Adversity, Religion, and Change in Adult Mental Health.
Jung, Jong Hyun
2018-02-01
Research indicates that childhood adversity is associated with poor mental health in adulthood. The purpose of this study is to examine whether the deleterious long-term effects of childhood adversity on adult mental health are reduced for individuals who are involved in religious practices. Using longitudinal data from a representative sample of American adults ( N = 1,635), I find that religious salience and spirituality buffer the noxious effects of childhood abuse on change in positive affect over time. By contrast, these stress-buffering properties of religion fail to emerge when negative affect serves as the outcome measure. These results underscore the importance of religion as a countervailing mechanism that blunts the negative impact of childhood abuse on adult mental health over time. I discuss the theoretical implications of these findings for views about religion, childhood adversity, and mental health.
Grandmother Involvement as a Protective Factor for Early Childhood Social Adjustment

2010-01-01
Despite high rates of grandmother involvement with young grandchildren, very little research has examined the associations between non-residential grandmother involvement and grandchild social adjustment. The present study draws 127 families enrolled in the Family Transitions Project to consider the degree to which mother-reported maternal grandmother involvement buffers 3- and 4-year old grandchildren from economic, parenting, and child temperamental risks for reduced social competence and elevated externalizing behaviors. Findings indicate that higher levels of mother-reported grandmother involvement reduced the negative association between observed grandchild negative emotional reactivity and social competence. Further, high levels of mother-reported grandmother involvement protected grandchildren from the positive association between observed harsh mother parenting and grandchild externalizing behaviors. These findings underscore the relevance of moving beyond the nuclear family to understand factors linked to social adjustment during early childhood. PMID:20954774
Personality in 100,000 Words: A large-scale analysis of personality and word use among bloggers
Yarkoni, Tal
2010-01-01
Previous studies have found systematic associations between personality and individual differences in word use. Such studies have typically focused on broad associations between major personality domains and aggregate word categories, potentially masking more specific associations. Here I report the results of a large-scale analysis of personality and word use in a large sample of blogs (N=694). The size of the dataset enabled pervasive correlations with personality to be identified for a broad range of lexical variables, including both aggregate word categories and individual English words. The results replicated category-level findings from previous offline studies, identified numerous novel associations at both a categorical and single-word level, and underscored the value of complementary approaches to the study of personality and word use.

The impact of bullying in all forms on the mental health and safety of adolescents is of particular interest, especially in the wake of new methods of bullying that victimize youths through technology. The current study examined the relationship between victimization from both physical and cyber bullying and adolescent suicidal behavior. Violent behavior, substance use, and unsafe sexual behavior were tested as mediators between two forms of bullying, cyber and physical, and suicidal behavior. Data were taken from a large risk-behavior screening study with a sample of 4,693 public high school students (mean age = 16.11, 47 % female). The study's findings showed that both physical bullying and cyber bullying associated with substance use, violent behavior, unsafe sexual behavior, and suicidal behavior. Substance use, violent behavior, and unsafe sexual behavior also all associated with suicidal behavior. Substance use and violent behavior partially mediated the relationship between both forms of bullying and suicidal behavior. The comparable amount of variance in suicidal behavior accounted for by both cyber bullying and physical bullying underscores the important of further cyber bullying research. The direct association of each risk behavior with suicidal behavior also underscores the importance of reducing risk behaviors. Moreover, the role of violence and substance use as mediating behaviors offers an explanation of how risk behaviors can increase an adolescent's likelihood of suicidal behavior through habituation to physical pain and psychological anxiety.

The present study assessed a developmental task theory of romantic relationships by examining associations between romantic relationship qualities and adjustment across 9 years using a community based sample of 100 male and 100 female participants (M age Wave 1 = 15.83) in a Western U.S. city. Using multilevel modeling, the study examined the moderating effect of age on links between romantic relationship qualities and adjustment. Consistent with developmental task theory, high romantic quality was more associated with internalizing symptoms and dating satisfaction during young adulthood than adolescence. Romantic relationship qualities were also associated with externalizing symptoms and substance use, but the degree of association was consistent across ages. The findings underscore the significance of romantic relationship qualities across development. PMID:26283151

Although many studies link teamwork in health care settings to patient safety, evidence linking teamwork to hospital worker safety is lacking. This study addresses this gap by providing evidence linking teamwork perceptions in hospital workers to worker injuries, and further, finds a linkage between manager commitment to safety and teamwork. Organizational records of worker injuries and survey responses regarding management commitment to safety and teamwork from 446 hospital workers within 42 work units in a multi-site hospital system were examined. Results underscored the particular importance of teamwork on worker injuries as well as the importance of management commitment to safety as relating to teamwork. To improve worker safety, organizational leaders and unit managers should work to maintain environments wherein teamwork can thrive.

We examine the relation between testosterone, cortisol, and financial decisions in a sample of naïve investors. We find that testosterone level is positively related to excess risk-taking, whereas cortisol level is negatively related to excess risk-taking (correlation coefficient [r]: 0.75 and -0.21, respectively). Additionally, we find support for the dual-hormone hypothesis in a financial context. Specifically, the testosterone-to-cortisol ratio is significantly related to loss aversion. Individuals with a higher ratio are 3.4 times more likely to sell losing stocks (standard error [SE]: 1.63). Furthermore, we find a positive feedback loop between financial success, testosterone, and cortisol. Specifically, financial success is significantly related to higher post-trial testosterone and cortisol by a factor of 0.53 (SE: 0.14). Finally, we find that in a competitive environment, testosterone level increases significantly, leading to greater risk-taking than in noncompetitive environment. Overall, this study underscores the importance of the endocrine system on financial decision-making. The results of this study are relevant to a broad audience, including investors looking to optimize financial performance, industry human resources, market regulators, and researchers.

Messenger, Scott; Walker, Robert M.
2015-01-01
Laboratory analysis of cometary samples have been enabled by collection of cometary dust in the stratosphere by high altitude aircraft and by the direct sampling of the comet Wild-2 coma by the NASA Stardust spacecraft. Cometary materials are composed of a complex assemblage of highly primitive, unprocessed interstellar and primordial solar system materials as well as a variety of high temperature phases that must have condensed in the inner regions of the protoplanetary disk. These findings support and contradict conclusions of comet properties based solely on astronomical observations. These sample return missions have instead shown that there is a continuity of properties between comets and asteroids, where both types of materials show evidence for primitive and processed materials. Furthermore, these findings underscore the importance and value of direct sample return. There will be great value in comparing the findings of the Stardust cometary coma sample return mission with those of future asteroid surface sample returns OSIRIS-REx and Hayabusa II as well as future comet nucleus sample returns.

The authors examined the moderating role of adolescent's gender and father's education on the associations between perceived paternal parenting styles and self-efficacy in a socioeconomical diverse sample of Iranian ado-lescents (n = 382). Results revealed that paternal authoritative parenting was significantly and positively related to self-efficacy. Interestingly, a significant and positive relation was also found between paternal authoritarian parenting and self-efficacy. This finding might have been the result of the fact that this study was conducted as part of a collectivist culture. In addition, the results indicated that boys who perceived their fathers as highly authoritative indicated higher self-efficacy than girls did. Furthermore, the findings demonstrated that higher educational levels attenuate the negative impact of the permissive parenting style on self-efficacy. The present findings underscore the need to focus on the role of gender and father's education when assessing the link between parenting style and adolescents' self-efficacy.

Objective This study examines the influence of therapist and youth characteristics on post-discharge outcomes from intensive in-home therapy. Method Data for 1,416 youth and 412 therapists were obtained from a behavioral health services provider. The Huber–White method was used to account for nested data; ordered logistic regression was employed to assess outcomes. Results Therapist gender and employment stability were significantly associated with youth outcomes. The likelihood of an undesirable outcome was significantly less for cases with female therapists. Conclusion Findings underscore the need for additional study concerning the impact of therapist characteristics and stability on youth outcomes, and to improve the understanding of the relationship between the two. Future studies in these areas would advance social work practice in family-based treatment programs. PMID:24944505
Gene–Environment Interactions and Intermediate Phenotypes: Early Trauma and Depression
Hornung, Orla P.; Heim, Christine M.
2013-01-01
This review focuses on current research developments in the study of gene by early life stress (ELS) interactions and depression. ELS refers to aversive experiences during childhood and adolescence such as sexual, physical or emotional abuse, emotional or physical neglect as well as parental loss. Previous research has focused on investigating and characterizing the specific role of ELS within the pathogenesis of depression and linking these findings to neurobiological changes of the brain, especially the stress response system. The latest findings highlight the role of genetic factors that increase vulnerability or, likewise, promote resilience to depression after childhood trauma. Considering intermediate phenotypes has further increased our understanding of the complex relationship between early trauma and depression. Recent findings with regard to epigenetic changes resulting from adverse environmental events during childhood promote current endeavors to identify specific target areas for prevention and treatment schemes regarding the long-term impact of ELS. Taken together, the latest research findings have underscored the essential role of genotypes and epigenetic processes within the development of depression after childhood trauma, thereby building the basis for future research and clinical interventions.

Masui, H.
1999-11-26
Inspired by the pencil glide theory for b.c.c. metal, modified pencil glide theory for f.c.c. metal was proposed, dividing the 12 glide systems of f.c.c. metal into three groups individually composed of eight {l{underscore}brace}111{r{underscore}brace}{l{underscore}angle}110{r{underscore}angle} glide systems around the principal axes X[100], Y[010] and Z[001]. These assumptions yielded two mathematical solutions {Omega}(3) and {Omega}(1). In {Omega}(3), from the three groups with four complete conjugated glide systems composed of, respectively, two glide systems of common {l{underscore}angle}110{r{underscore}angle} direction, only one group with the maximum plastic work may operate if the requirements are satisfied, otherwise glide systems in {Omega}(1) where one of the fourmore » conjugated glide systems is zero are activated. The model considering the 12 glide systems of f.c.c. as a whole explained many experimentally stable orientations in axisymmetric and rolling deformation. The differences between the two pencil glide theories for b.c.c. and f.c.c. are also discussed with data.« less
A Second Look at the Process of Occupational Feminization and Pay Reduction in Occupations.
Mandel, Hadas
2018-04-01
Using the IPUMS-USA data for the years 1960-2015, this study examines trends in the effect of occupational feminization on occupational pay in the U.S. labor market and explores some of the mechanisms underlying these trends. The findings show that the (negative) association between occupational feminization and occupational pay level has declined, becoming insignificent in 2015. This trend, however, is reversed after education is controlled for at the individual as well as the occupational level. The two opposite trends are discussed in light of the twofold effect of education: (1) the entry of women into occupations requiring high education, and (2) the growing returns to education and to occupations with higher educational requirements. These two processes have concealed the deterioration in occupational pay following feminization. The findings underscore the significance of structural forms of gender inequality in general, and occupational devaluation in particular.

The current study examined how parental ethnic socialization informed adolescents' ethnic identity development and, in turn, youths' psychosocial functioning (i.e., mental health, social competence, academic efficacy, externalizing behaviors) among 749 Mexican-origin families. In addition, school ethnic composition was examined as a moderator of these associations. Findings indicated that mothers' and fathers' ethnic socialization were significant longitudinal predictors of adolescents' ethnic identity, although fathers' ethnic socialization interacted significantly with youths' school ethnic composition in 5 th grade to influence ethnic identity in 7 th grade. Furthermore, adolescents' ethnic identity was significantly associated with increased academic self-efficacy and social competence, and decreased depressive symptoms and externalizing behaviors. Findings support theoretical predictions regarding the central role parents play in Mexican-origin adolescents' normative developmental processes and adjustment and, importantly, underscore the need to consider variability that is introduced into these processes by features of the social context such as school ethnic composition.

Purpose of review Cannabis use disorders (CUDs) are prevalent worldwide. Current epidemiological studies underscore differences in behaviors that contribute to cannabis use across cultures that can be leveraged towards prevention and treatment of CUDs. This review proposes a framework for understanding the effects of cross-cultural differences on psychological, neural, and genomic processes underlying CUDs that has the potential to inform global policies and impact global public health. Recent findings We found that cultural factors may influence (1) the willingness to acknowledge CUD-related symptoms among populations of different countries, and (2) neural responses related to the sense of self, perception, emotion, and attention. These findings leverage the potential effects of culture on neural mechanisms underlying CUDs. Summary As the number of individuals seeking treatment for CUDs increases globally, it is imperative to incorporate cultural considerations to better understand and serve differing populations and develop more targeted treatment strategies and interventions.

Baker, Christopher A.; Manuelidis, Laura
2003-01-01
Previous studies in Creutzfeldt-Jakob disease (CJD) have shown that myeloid cells in the periphery as well as derivative microglial cells in the brain are infectious. Microglia can show an activated phenotype before prion protein (PrP) pathology is detectable in brain, and isolated infectious microglia contain very little PrP. To find whether a set of inflammatory genes are significantly induced or suppressed with infection, we analyzed RNA from isolated microglia with relevant cDNA arrays, and identified 30 transcripts not previously examined in any transmissible spongiform encephalopathy. This CJD expression profile contrasted with that of uninfected microglia exposed to prototypic inflammatory stimuli such as lipopolysaccharide and IFN-, as well as PrP amyloid. These findings underscore inflammatory pathways evoked by the infectious agent in brain. Transcript profiles unique for CJD microglia and other myeloid cells provide opportunities for more sensitive preclinical diagnoses of infectious and noninfectious neurodegenerative diseases.
Stress of parent care: positive and negative effects of women's other roles.
Stephens, M A; Townsend, A L
1997-06-01
The present study focused on 296 women who were primary caregivers to an ill or disabled parent or parent-in-law and who simultaneously occupied 3 other roles as mother, wife, and employee. All women lived in separate households from their impaired parent and had at least 1 child 25 years of age or younger living at home. It was predicted that stress in the roles of mother, wife, and employee would exacerbate the effects of stress in the parent care role on psychological well-being (depression and life satisfaction) and that rewards in these 3 additional roles would buffer the effects of parent care stress. For all 3 additional roles, findings supported the stress exacerbation hypothesis. In contrast, only the employee role supported the stress-buffering hypothesis. These findings underscore the complex relationships that often exist between women's multiple role experiences and their psychological well-being.

Exercise-based cardiac rehabilitation (CR) programs help patients with coronary heart disease (CHD) reduce their risk of recurrent cardiac illness, disability, and death. However, men with CHD and Type 2 diabetes mellitus (T2DM) demonstrate lower attendance and completion of CR despite having a poor prognosis. Drawing on gender and masculinity theory, we report on a qualitative study of 16 Canadian diabetic men recently enrolled in CR. Major findings reflect two discursive positions men assumed to regain a sense of competency lost in illness: (a) working with the experts, or (b) rejection of biomedical knowledge. These positions underscore the varied and sometimes contradictory responses of seriously ill men to health guidance. Findings emphasize the priority given to the rehabilitation of a positive masculine identity. The analysis argues that gender, age, and employment status are powerful mechanisms of variable CR participation. © The Author(s) 2015.
Clinical encounters between nurses and First Nations women in a Western Canadian hospital.
Browne, Annette J
2007-05-01
Based on findings from an ethnographic study, this paper explores the sociopolitical context of nurses' encounters with First Nations women in a Western Canadian hospital. Data were collected using in-depth interviews and participant observation of clinical encounters involving nurses and First Nations women who were in-patients in the hospital. Four themes in the data are discussed: relating across presumed "cultural differences"; constructing the Other; assumptions influencing clinical practice; and responding to routine patient requests. The findings illustrate how discourses and assumptions about Aboriginal people, culture, and presumed differences can become interwoven into routine clinical encounters. These results highlight the importance of analyzing health-care encounters in light of the wider sociopolitical and historical forces that give rise to racialization, culturalism and Othering, and underscore the need for critical awareness of these issues among nurses and other heath-care providers.

Effects of Epilepsy on Language Functions: Scoping Review and Data Mining Findings.
Dutta, Manaswita; Murray, Laura; Miller, Wendy; Groves, Doyle
2018-03-01
This study involved a scoping review to identify possible gaps in the empirical description of language functioning in epilepsy in adults. With access to social network data, data mining was used to determine if individuals with epilepsy are expressing language-related concerns. For the scoping review, scientific databases were explored to identify pertinent articles. Findings regarding the nature of epilepsy etiologies, patient characteristics, tested language modalities, and language measures were compiled. Data mining focused on social network databases to obtain a set of relevant language-related posts. The search yielded 66 articles. Epilepsy etiologies except temporal lobe epilepsy and older adults were underrepresented. Most studies utilized aphasia tests and primarily assessed single-word productions; few studies included healthy control groups. Data mining revealed several posts regarding epilepsy-related language problems, including word retrieval, reading, writing, verbal memory difficulties, and negative effects of epilepsy treatment on language. Our findings underscore the need for future specification of the integrity of language in epilepsy, particularly with respect to discourse and high-level language abilities. Increased awareness of epilepsy-related language issues and understanding the patients' perspectives about their language concerns will allow researchers and speech-language pathologists to utilize appropriate assessments and improve quality of care.

One of the most consistent findings in developmental criminology is the "age-crime curve"-the observation that criminal behavior increases in adolescence and decreases in adulthood. Recently, Brown and Males (Justice policy J 8:1-30, 2011) conducted an analysis of aggregate arrest, poverty, and population data from California and concluded that the widely-observed adolescent peak in rates of offending is not a consequence of developmental factors, but rather an artifact of age differences in economic status. Youngsters, they argue, offend more than adults because they are poorer than adults. The present study challenges Brown and Males' proposition by analyzing data from the National Longitudinal Study of Youth (NLSY97; N = 8,984; 51% female; 26% Black, 21% Hispanic, 52% non-Black, non-Hispanic; ages 12-18 at Wave 1), which collected measures of criminal behavior and economic status at multiple time points. Consistent with scores of other studies, we find that criminal offending peaks in adolescence, even after controlling for variation in economic status. Our findings both counter Brown and Males' claim that the age-crime curve is illusory and underscore the danger of drawing inferences about individual behavior from analysis of aggregated data.
Abstinence at Successful Discharge in Publicly Funded Addiction Health Services

2016-01-01
Abstinence at successful discharge in substance use disorder treatment is important to reducing relapse rates and increasing long-term recovery from substance use disorders. However, few studies have examined abstinence as an essential component of successful discharge. This study examined rates and correlates of reported abstinence (nonuse of drugs 30 days prior to successful discharge) among clients attending publicly funded treatment in Los Angeles County, California. Finding show that only 36% of clients who were successfully discharged reported abstinence. Black clients were less likely than non-Hispanic Whites to report abstinence at successful discharge. Clients in methadone treatment programs were less likely than outpatient clients to report abstinence, whereas clients referred to treatment through the legal system (Proposition 36) were more likely to report abstinence compared to self-referred clients. Findings underscore the importance of systematic assessment of abstinence in determining successful discharge and provide a basis for further examination of strategies to improve abstinence and reduce relapse.

Pharmacological Approaches for Treatment-resistant Bipolar Disorder
Poon, Shi Hui; Sim, Kang; Baldessarini, Ross J.
2015-01-01
Bipolar disorder is prevalent, with high risks of disability, substance abuse and premature mortality. Treatment responses typically are incomplete, especially for depressive components, so that many cases can be considered “treatment resistant.” We reviewed reports on experimental treatments for such patients: there is a striking paucity of such research, mainly involving small incompletely controlled trials of add-on treatment, and findings remain preliminary. Encouraging results have been reported by adding aripiprazole, bupropion, clozapine, ketamine, memantine, pramipexole, pregabalin, and perhaps tri-iodothyronine in resistant manic or depressive phases. The urgency of incomplete responses in such a severe illness underscores the need for more systematic, simpler, and better controlled studies in more homogeneous samples of patients. PMID:26467409

The following study assessed whether future orientation mediated the effects of peer norms and parental monitoring on delinquency and substance use among 549 African American adolescents. Structural equation modeling computed direct and indirect (meditational) relationships between parental monitoring and peer norms through future orientation. Parental monitoring significantly correlated with lower delinquency through future orientation ( B = -.05, standard deviation = .01, p < .01). Future orientation mediated more than quarter (27.70%) of the total effect of parental monitoring on delinquency. Overall findings underscore the importance of strengthening resilience factors for African American youth, especially those who live in low-income communities.

The present study examined invented spelling of pinyin (a phonological coding system for teaching and learning Chinese words) in relation to subsequent Chinese reading development. Among 296 Chinese kindergartners in Beijing, independent invented pinyin spelling was found to be uniquely predictive of Chinese word reading 12 months later, even with Time 1 syllable deletion, phoneme deletion, and letter knowledge, in addition to the autoregressive effects of Time 1 Chinese word reading, statistically controlled. These results underscore the importance of children's early pinyin representations for Chinese reading acquisition, both theoretically and practically. The findings further support the idea of a universal phonological principle and indicate that pinyin is potentially an ideal measure of phonological awareness in Chinese.
Predictors of adaptation in Icelandic and American families of young children with chronic asthma.

2005-01-01
The purposes of this international study were to determine the predictors of adaptation and to assess potential moderating effects of parents' sense of coherence and family hardiness on the relationship of severity of illness of a child with asthma and family and caregiving demands as predictors of family adaptation. For both parents, sense of coherence and family hardiness predicted family adaptation. Icelandic mothers perceived their family's adaptation more favorably than did their American counterparts. For the fathers, family demands predicted adaptation. Sense of coherence moderated the effect of family demands on adaptation for both parents. These findings underscore the importance of strengthening individual and family resiliency as a mechanism for improving family adaptation.
A three-component model of future time perspective across adulthood.
Rohr, Margund K; John, Dennis T; Fung, Helene H; Lang, Frieder R
2017-11-01
Although extensive findings underscore the relevance of future time perspective (FTP) in the process of aging, the assumption of FTP as a unifactorial construct has been challenged. The present study explores the factorial structure of the FTP scale (Carstensen & Lang, 1996) as one of the most widely used measures (Ntotal = 2,170). Results support that FTP reflects a higher-order construct that consists of 3 interrelated components-Opportunity, Extension, and Constraint. It is suggested that the flexible usage of the FTP scale as an all compassing 10-item measure or with focus on specific components depends on the concrete research question.

The purpose of this study was to explore individual and structural factors associated with employment among young transgender women (TW) of color. Sixty-five trans women of color were recruited from the Transgender Legal Defense and Education Fund to complete a 30-min interviewer-assisted survey assessing sociodemographics, housing, workplace discrimination, job-seeking self-efficacy, self-esteem, perceived public passability, and transactional sex work. Logistic regression models revealed that stable housing (structural factor) and job-seeking self-efficacy (individual factor) were significantly associated with currently being employed. Our findings underscore the need for multilevel approaches to assist TW of color gain employment.
Can guilt lead to psychological growth following trauma exposure?

With the growing interest in posttraumatic growth (PTG) and its predictors, this study examined the relationship between trauma-related guilt and PTG in a sample of veterans over time. Self-reported guilt, PTG, and posttraumatic stress disorder (PTSD) symptoms were measured in combat veterans and prisoners of war (POWs). Positive correlations were found between guilt, PTSD, and PTG levels. Hierarchical regression revealed that initial guilt levels predicted subsequent PTG controlling for initial PTSD in combat veterans but not in POWs. The findings suggest that posttraumatic growth can be facilitated by trauma-related guilt, underscoring the complex relationship between positive and negative trauma outcomes.

2012-01-01
Alumni of an undergraduate Deaf studies program completed an online survey about their education and employment after graduation and their perceptions of their internship and undergraduate academic program. Demographically, this population of Deaf studies alumni represented a higher percentage of women and dual-major graduates than was present in the general university population. It was found that most of the alumni reported using the knowledge and skills from the Deaf studies program in their current job. Current employment among alumni was almost 100%, and most of the alumni had positive perceptions regarding their personal, academic, and professional growth as it related to their internship and undergraduate Deaf studies program. The study findings underscore the need for continued support of Deaf studies programs. Suggestions are provided for program directors regarding the development of internships and academic programs for students in Deaf studies.

The purpose of this descriptive correlational study was to describe predictors of depressive symptoms among N=70 seropositive Botswana men and women residing in Gaborne, Botswana. A demographic questionnaire, the Center for Epidemiologic Studies Depression Scale, (CESD-D), and the SF-36 [Quality of life] were administered. The questionnaires were translated and back translated in Setswana and administered by Batswana men and women. The results of the regression analyses resulted in two calculated models. In the first Model energy/fatigue explained 46% of the variance in depressive symptoms (P=.000), and in the second Model energy/fatigue and role limitations on emotional well-being explained 50% of the variance in depressive symptoms respectively. The study findings underscore the need for mental health services for seropositive Batswana men and women. Copyright © 2016 Elsevier Inc. All rights reserved.

A cross sectional study among 450 individuals selected by strafified random sampling was carried out in rural Goa to find out the prevalence of cysticercosis and taeniasis, as well as to study the role of various factors associated with this diseases. The study participants were administered a pre-tested structured questionnaire and subsequently blood and stool samples were examined. SPSS software was used to analyze the data statistically. The sero-prevalence of cysterosis was 22.4%, which increased with age. Prevalence of taeniasis was 9.7% by stool examination. Individuals with taeniasis were thrice more likely to have cysticercosis; however no association between sero-positivity for cysterosis and pork consumption as well as religion could be established. The study confirmed a high sero-prevalence of cysticercosis in Goa underscoring the need to general awareness about good cooking habits and sanitation.

This study is designed to provide an empirical conceptualization of daily hassles among unaccompanied refugees, and whether they might affect mental health of young refugees after resettlement. First, we examined the underlying structure of daily hassles conceptualized as measuring general and acculturation-specific hassles. Second, we examined whether these two distinct categories of daily hassles significantly contribute to depression above and beyond the impact of premigration trauma. The study was based on self-report questionnaire data collected from 895 unaccompanied refugees who had been granted residence in Norway. Using structural equation modeling, the results confirmed the grouping of hassles in two general categories, which explained 43% of the variance in depression. The findings underscore the importance of current life conditions for unaccompanied refugees' mental health.
Power fosters context-independent, analytic cognition.
Miyamoto, Yuri; Ji, Li-Jun
2011-11-01
The present research tested the hypothesis that power, defined as the capacity to influence others, promotes analytic cognitive processing, by examining the use of linguistic categories and the categorization of objects. Supporting the hypothesis, recalling instances of influencing others facilitated the use of adjectives and discouraged the use of verbs to describe others (Study 1). Recalling instances of influencing others also promoted taxonomic, instead of thematic, categorization (Study 2). Furthermore, the authors also examined the effect of power in a real-life context. They examined whether socioeconomic status (SES) differences in cognitive processing can be partly explained by sense of agency, an antecedent of power (Study 3); high SES individuals made more taxonomic categorization than did low SES individuals, and a sense of agency partially mediated the SES differences in categorization. These findings underscore the role of power in shaping cognitive processes.

Evidence underscores that empowerment is central to improve the elderly residents' quality of life. In truth, empowerment is a process through which individuals gain better control over their life. The aim of this study was to explore how perceived empowerment influence on the quality of life among elderly Malay residents. A focus ethnographic approach was employed in a Malaysian residential home between May 2011 and January 2012. Data were gathered from participant observations, field notes, in-depth interviews, and exploring related documents. The analysis of the data gathered in the current study resulted in the development of three themes - social life and its requirements, caregivers' skills empowerment, and listening and supporting. Findings of the study provide new insights that are useful in charting new guideline for care providers and policy makers to improve the elderly residents' quality of life.

Recent studies have shown that language processing is grounded in actions. Multiple independent research findings indicate that children with specific language impairment (SLI) show subtle difficulties beyond the language domain. Uncertainties remain on possible association between body-mediated, non-linguistic expression of verbs and early manifestation of SLI during verb acquisition. The present study was conducted to determine whether verb production through non-linguistic modalities is impaired in children with SLI. Children with SLI (mean age 41 months) and typically developing children (mean age 40 months) were asked to recognize target verbs while viewing video clips showing the action associated with the verb (verb-recognition task) and to enact the action corresponding to the verb (verb-enacting task). Children with SLI performed more poorly than control children in both tasks. The present study demonstrates that early language impairment emerges at the bodily level. These findings are consistent with the embodied theories of cognition and underscore the role of action-based representations during language development. Copyright © 2014 Elsevier Ltd.

Boredom begs to differ: Differentiation from other negative emotions.
van Tilburg, Wijnand A P; Igou, Eric R
2017-03-01
Boredom research is booming. Nonetheless, a comprehensive understanding of boredom in relation to other negative emotions is lacking. This ambiguity impedes accurate interpretation of boredom's causes and consequences. To gain more insights into boredom, we examined in detail how it differs from a range of other negative experiences, namely sadness, anger, frustration, fear, disgust, depression, guilt, shame, regret, and disappointment. Our research indicates that the appraisals associated with boredom distinguish it clearly from other negative emotions; conceptually (Study 1), in terms of state experiences (Study 2), and in terms of individual differences in these experiences (Study 3). Our findings suggest that boredom is mild in negative valence, low in arousal, is associated with low perceived challenge and low perceived meaningfulness, and has low relevance to moral judgment and behavior. Boredom also involves low attention given to situations and tasks, and the lack of perceived meaningfulness and attention associated with boredom emerged as particularly distinctive characteristics. The findings underscore the importance of carefully discriminating boredom from other emotions in experimental induction, psychometric assessment, and conceptual discussion.

As a biologically-mediated pathway between adversity and declines in physical health, allostatic load has been frequently hypothesized as a potential contributor to racial disparities in birth outcomes, but empirical evidence is lacking. The purpose of this study was to examine the relationships between maternal preconception allostatic load, race, and adverse birth outcomes within the context of neighborhood-level poverty using data from the Bogalusa Heart Study. Allostatic load was quantified as a count of regulatory biomarkers falling in the highest risk quartile of the sample distribution as measured from a physical examination that took place prior to conception. Consistent with previous findings, African American women resided in more impoverished neighborhoods and had higher allostatic load scores compared to whites; however, allostatic load was not associated with preterm birth or low birthweight in fully adjusted models. These results underscore a need for further refinement of both biologic and contextual measures that capture holistically the way in which stressful conditions and experiences encountered across the life-course influence health potentials and engender inequities in reproductive health outcomes.

In the current study, we explored patterns of change in Black emerging adults’ racial identity beliefs during the transition to adulthood, assessed neighborhood racial composition effects on Black emerging adults’ racial identity beliefs, and tested the moderating effects of neighborhood racial composition on the relationship between Black emerging adults’ racial identity beliefs and depressive symptoms over time. Participants in the current study included 570 Black adolescents (52% female) who were transitioning into adulthood (senior year of high school through 5 years post-high school). We did not find average patterns of change in Black emerging adults’ racial identity beliefs over time. Further, neighborhood racial composition did not predict participants’ beginning status or growth in racial identity beliefs over time. We, however, found evidence that neighborhood racial composition may moderate the association between Black emerging adults’ racial identity beliefs and symptoms of depression over time. Findings from the current study underscore the importance of considering how the larger social context may interact with individuals’ racial identity beliefs to influence Black emerging adults’ psychological health.

The reasons for the comorbidity between depressed mood and poor sleep are not well understood. Participants were 5172 adults aged 50 years and older from the English Longitudinal Study of Ageing. Sleep was measured via self-report and depressive symptoms using the Centre for Epidemiological Studies Depression scale. Greater depressive symptoms and sleep complaints were associated with female sex, non-cohabitation, relative poverty, smoking, infrequent physical activity, infrequent alcohol consumption, higher body mass index (BMI), diagnosis of hypertension, coronary heart disease, diabetes/high blood glucose, pulmonary disease, arthritis, and higher levels of fibrinogen and C-reactive protein (all p < 0.05). At a 4-year follow-up, depressive symptoms and sleep complaints were both predicted by baseline depressive symptoms and sleep complaints, relative poverty, smoking, physical inactivity, BMI, and arthritis (all p < 0.05). Depressive symptoms and sleep complaints share a range of correlates cross-sectionally and prospectively. These findings highlight the common comorbidity between depressive symptoms and sleep complaints underscoring the need for further research to understand their combined detrimental effect on long-term health and wellbeing.

While empirical evidence continues to show that people living in low socio-economic status neighbourhoods are less likely to engage in health-enhancing behaviour, our understanding of why this is so remains less than clear. We suggest that two changes could take place to move from description to understanding in this field; (i) a move away from the established concept of individual health behaviour to a contextualised understanding of health practices; and (ii) a switch from focusing on health inequalities in outcomes to health inequities in conditions. We apply Pierre Bourdieu's theory on capital interaction but find it insufficient with regard to the role of agency for structural change. We therefore introduce Amartya Sen's capability approach as a useful link between capital interaction theory and action to reduce social inequities in health-related practices. Sen's capability theory also elucidates the importance of discussing unequal chances in terms of inequity, rather than inequality, in order to underscore the moral nature of inequalities. We draw on the discussion in social geography on environmental injustice, which also underscores the moral nature of the spatial distribution of opportunities. The article ends by applying this approach to the 'Interdisciplinary study of inequalities in smoking' framework. © 2013 The Authors.

Pursuit of comfort and pursuit of harmony: culture, relationships, and social support seeking.
Kim, Heejung S; Sherman, David K; Ko, Deborah; Taylor, Shelley E
2006-12-01
This research examined whether people from collectivistic cultures are less likely to seek social support than are people from individualistic cultures because they are more cautious about potentially disturbing their social network. Study 1 found that Asian Americans from a more collectivistic culture sought social support less and found support seeking to be less effective than European Americans from a more individualistic culture. Study 2 found that European Americans' willingness to seek support was unaffected by relationship priming, whereas Asian Americans were willing to seek support less when the relationship primed was closer to the self. Study 3 replicated the results of Study 2 and found that the tendency to seek support and expect social support to be helpful as related to concerns about relationships. These findings underscore the importance of culturally divergent relationship patterns in understanding social support transactions.
The influence of major dietary fatty acids on insulin secretion and action.
López, Sergio; Bermúdez, Beatriz; Abia, Rocío; Muriana, Francisco J G
2010-02-01
To briefly summarize recent advances towards understanding the influence of major dietary fatty acids on beta-cell function and evaluate their implications for insulin resistance. Studies in humans have shown that beta-cell function and insulin sensitivity improve progressively in the postprandial period as the proportion of monounsaturated fatty acids (MUFAs) with respect to saturated fatty acids (SFAs) in dietary fats increases. However, cell-culture experiments have revealed a dichotomy in the ability of fatty acids to moderate hyperactivity of, and induce lipotoxicity in, beta-cells. There are also some novel findings regarding the ability of HDL to protect beta-cells against oxidized LDL-induced apoptosis in vitro and of reconstituted HDL to attenuate insulin resistance in vivo. These findings raise new questions regarding the contribution of dietary fatty acids to insulin secretion and action. These new findings point to a critical role for major dietary fatty acids in the etiology and pathogenesis of diabetes, which appears to be of particular relevance during postprandial periods and mainly depends on the fatty acid type. This underscores the importance of dietary fatty acids in standard diabetes management.

Trans-resveratrol is a nutraceutical with known antioxidant, anti-inflammatory, cardioprotective, and anti-apoptotic properties. The aim of this study was to evaluate the effects of resveratrol on heart mitochondria. Resveratrol significantly decreased Fe(2+) + ascorbate oxidant system-induced lipid peroxide levels, preserved physiological levels of glutathione, and increased nitric oxide (NO) levels in mitochondria. Under calcium-mediated stress, there was a 2.7-fold increase in the NO levels, and a mild decoupling in the mitochondrial respiratory chain. These results provide a mechanism for and support the beneficial effects of resveratrol under pathological conditions induced by oxidative stress and calcium overload. In addition, these findings underscore the usefulness of resveratrol in the prevention of cardiovascular diseases.

This study explored the clinical profiles of 77 female teenager survivors of sexual abuse and examined the association of abuse-related and personal variables with suicidal ideations. Analyses revealed that 64% of participants experienced suicidal ideations. Findings from classification and regression tree analysis indicated that depression, posttraumatic stress symptoms, and hopelessness discriminated profiles of suicidal and nonsuicidal survivors. The elevated prevalence of suicidal ideations among adolescent survivors of sexual abuse underscores the importance of investigating the presence of suicidal ideations in sexual abuse survivors. However, suicidal ideation is not the sole variable that needs to be investigated; depression, hopelessness and posttraumatic stress symptoms are also related to suicidal ideations in survivors and could therefore guide interventions.

New experimental tools are urgently required to better understand the metastatic process. The importance of such tools is underscored by the fact that many anti-cancer therapies are generally ineffective against established metastases. This makes a major contribution to the fact that metastatic spread is responsible for over 90% of cancer patient deaths. It was therefore timely that the recent "Seed and Soil: In Vivo Models of Metastasis" conference held in Berlin, Germany (27-29 of November 2017) aimed to give an in-depth overview of the latest research models and tools for studying metastasis, and to showcase recent findings from world-leading metastasis researchers. This Meeting Report summarises the major themes of this ground-breaking conference.
Gender harassment: broadening our understanding of sex-based harassment at work.
Leskinen, Emily A; Cortina, Lilia M; Kabat, Dana B
2011-02-01
This study challenges the common legal and organizational practice of privileging sexual advance forms of sex-based harassment, while neglecting gender harassment. Survey data came from women working in two male-dominated contexts: the military and the legal profession. Their responses to the Sexual Experiences Questionnaire (SEQ) revealed five typical profiles of harassment: low victimization, gender harassment, gender harassment with unwanted sexual attention, moderate victimization, and high victimization. The vast majority of harassment victims fell into one of the first two groups, which described virtually no unwanted sexual advances. When compared to non-victims, gender-harassed women showed significant decrements in professional and psychological well-being. These findings underscore the seriousness of gender harassment, which merits greater attention by both law and social science.
Current directions in non-invasive low intensity electric brain stimulation for depressive disorder.
Schutter, Dennis J L G; Sack, Alexander T
2014-01-01
Non-invasive stimulation of the human brain to improve depressive symptoms is increasingly finding its way in clinical settings as a viable form of somatic treatment. Following successful modulation of neural excitability with subsequent antidepressant effects, neural polarization by administrating weak direct currents to the scalp has gained renewed interest. A new wave of basic and clinical studies seems to underscore the potential therapeutic value of direct current stimulation in the treatment of depression. Issues concerning the lack of mechanistic insights into the workings of modifying brain function through neural polarization and how this process translates to its antidepressant properties calls for additional research. The range of its clinical applicability has yet to be established.

Patient navigation is increasingly employed to guide patients through cancer treatment. We assessed the elements of navigation that promoted patients' involvement in treatment among patients with breast and colorectal cancer that participated in a navigation study. We conducted qualitative analysis of 28 audiotaped and transcribed semi-structured interviews of navigated and unnavigated cancer patients. Themes included feeling emotionally and cognitively overwhelmed and desire for a strong patient-navigator partnership. Both participants who were navigated and those who were not felt that navigation did or could help address their emotional, informational, and communicational needs. The benefits of logistical support were cited less often. Findings underscore the salience of personal relationships between patients and navigators in meeting patients' emotional and informational needs.

Abstract Purpose: The purpose of this study was to explore individual and structural factors associated with employment among young transgender women (TW) of color. Methods: Sixty-five trans women of color were recruited from the Transgender Legal Defense and Education Fund to complete a 30-min interviewer-assisted survey assessing sociodemographics, housing, workplace discrimination, job-seeking self-efficacy, self-esteem, perceived public passability, and transactional sex work. Results: Logistic regression models revealed that stable housing (structural factor) and job-seeking self-efficacy (individual factor) were significantly associated with currently being employed. Conclusion: Our findings underscore the need for multilevel approaches to assist TW of color gain employment. PMID:28795154

This study examined the relative influences of PTSD, other psychopathology, and intimate partner alcohol and drug use on substance-related problems in U.S. veterans (242 couples, N = 484). Hierarchical regression analyses revealed that partner alcohol and drug use severity explained more variance in veteran alcohol use and drug use (20% and 13%, respectively) than did veteran PTSD, adult antisocial behavior, or depression symptoms combined (6% for veteran alcohol use; 7% for veteran drug use). Findings shed new light on the influence of relationship factors on veteran alcohol and drug use and underscore the importance of couples-oriented approaches to treating veterans with comorbid PTSD and substance abuse.

The present study examined factors that predicted favorable treatment outcomes among clinically referred conduct problem children (N = 105, ages 7-13) who received cognitive-behavioral treatment. Three domains (severity and breadth of child impairment, parent stress and psychopathology and family dysfunction) assessed at pretreatment were predicted to affect treatment outcome. The results only partially supported the prediction. Less dysfunction in each of the domains predicted who responded favorably to treatment on parent ratings of deviance and prosocial functioning but not on teacher ratings of these outcomes. The findings have implications for identifying youths who respond to available treatments. The results also underscore fundamental questions about the assessment of treatment effects and the criteria for evaluating outcome.

Research has not yet examined the relationship between psychological need satisfaction, sleep, mindfulness, and health-related quality of life in people living with HIV. This cross-sectional study ( N = 101; 84% male; mean age = 45.48, SD = 12.75) found need satisfaction to relate positively to physical and mental health. Sleep quality fully mediated the association with physical health and partially mediated the association with mental health. Furthermore, mindfulness related to higher sleep quality through higher need satisfaction. Findings underscore the role of need satisfaction in determining health-related quality of life and sleep quality in people living with HIV and suggest that mindfulness may facilitate need satisfaction.

Few studies examine physical environmental factors and their effects on staff health, effectiveness, work errors and job satisfaction. To address this gap, this study aims to examine environmental features and their role in medication and nursing errors in long-term care facilities. A mixed methodological strategy was used. Data were collected via focus groups, observing medication preparation and administration, and a nursing staff survey in four facilities. The paper reveals that, during the medication preparation phase, physical design, such as medication room layout, is a major source of potential errors. During medication administration, social environment is more likely to contribute to errors. Interruptions, noise and staff shortages were particular problems. The survey's relatively small sample size needs to be considered when interpreting the findings. Also, actual error data could not be included as existing records were incomplete. The study offers several relatively low-cost recommendations to help staff reduce medication errors. Physical environmental factors are important when addressing measures to reduce errors. The findings of this study underscore the fact that the physical environment's influence on the possibility of medication errors is often neglected. This study contributes to the scarce empirical literature examining the relationship between physical design and patient safety.
Neurodevelopment, GABA System Dysfunction, and Schizophrenia

The origins of schizophrenia have eluded clinicians and researchers since Kraepelin and Bleuler began documenting their findings. However, large clinical research efforts in recent decades have identified numerous genetic and environmental risk factors for schizophrenia. The combined data strongly support the neurodevelopmental hypothesis of schizophrenia and underscore the importance of the common converging effects of diverse insults. In this review, we discuss the evidence that genetic and environmental risk factors that predispose to schizophrenia disrupt the development and normal functioning of the GABAergic system.

Temporarily Disabled Workers Account For A Disproportionate Share Of Health Care Payments.
Gifford, Brian
2017-02-01
About one in four employees in a cohort of 408,000 US workers took a temporary leave of absence from work because of illness or injury in the period 2008-12. They accounted for nearly 60 percent (about $6.5 billion) of total worker health care and disability payments. This finding underscores the importance of workplace care management, lifestyle management, and health and safety efforts to prevent disability leaves.

One major goal in Neuroscience is the development of strategies promoting neural plasticity in the adult central nervous system, when functional recovery from brain disease and injury is limited. New evidence has underscored a pivotal role for cortical inhibitory circuitries in regulating plasticity both during development and in adulthood. This paper summarizes recent findings showing that the inhibition-excitation balance controls adult brain plasticity and is at the core of the pathogenesis of neurodevelopmental disorders like autism, Down syndrome, and Rett syndrome.

Among 23 pediatric renal dialysis patients, we obtained self-reported assessments of psychological adjustment and biochemical and subjective ratings of adherence. Findings indicate elevated levels of depressive symptoms and substantial nonadherence. Depressive symptoms were associated with higher levels of hopelessness, more negative self-perceptions, and more depressogenic attributional style. The psychological adjustment measures did not significantly correlate with adherence. Nonsignificant associations among different measures of adherence underscore its multifaceted nature. Implications for monitoring the adjustment of children on dialysis, assessing adherence, and future research are discussed.

Low socioeconomic status (SES) has been linked to HIV and sexually transmitted disease (STD) at a macro level because the majority of new cases of HIV infection in the world have been reported in underdeveloped or developing countries. However, empirical data on the relationship between individual SES and HIV/STD related risk have been mixed. Employing quantitative data from 454 female sex workers (FSWs), this study was designed to examine the profile of the study sample in terms of their individual SES, HIV/STD-related sexual risk across work locations with different social, cultural, and economic conditions; and to examine the relationship between work location and HIV-related risk behaviors, controlling for individual SES. We have shown in the current study that both SES and HIV/STD-related risk behaviors significantly differed by work location. However, the difference in individual SES was not sufficient to explain the difference of HIV/STD-related risk across the work locations. The findings underscore the need for effective prevention intervention efforts targeting FSWs in rural areas. Based on the findings, we also suggest that HIV/STD intervention efforts among FSWs should take the social and cultural contextual factors of their working environment (and sexual risks) into consideration.

Emotion regulation deficits have been implicated in anxiety and depressive disorders, and these internalising disorders are more prevalent in women than men. Few electrophysiological studies have investigated sex differences in emotional reactivity and emotion regulation controlling for menstrual phase. Event-related potentials (ERPs) were recorded from 28 early follicular women, 29 midluteal women, and 27 men who completed an emotion regulation task. A novel finding of increased N2 amplitude during suppression was found for midluteal women compared with men. These findings suggest midluteal women may be significantly less able to suppress cortical processing of negative stimuli compared to men. This ERP finding was complemented by behavioral ratings data which revealed that while both early follicular and midluteal women reported more distress than men, midluteal women also reported greater effort when suppressing their responses than men. P1 and N1 components were increased in midluteal women compared to men regardless of instructional set, suggesting greater early attentional processing. No sex or menstrual phase differences were apparent in P3 or LPP. This study underscores the importance of considering menstrual phase when examining sex differences in the cortical processing of emotion regulation and demonstrates that midluteal women may have deficits in down-regulating their neural and behavioural responses.

A Longitudinal Study of Lexical Development in Children Learning Vietnamese and English
Pham, Giang; Kohnert, Kathryn
2013-01-01
This longitudinal study modeled lexical development among children who spoke Vietnamese as a first language (L1) and English as a second language (L2). Participants (n=33, initial mean age of 7.3 years) completed a total of eight tasks (four in each language) that measured vocabulary knowledge and lexical processing at four yearly time points. Multivariate hierarchical linear modeling was used to calculate L1 and L2 trajectories within the same model for each task. Main findings included (a) positive growth in each language, (b) greater gains in English resulting in shifts toward L2 dominance, and (c) different patterns for receptive and expressive domains. Timing of shifts to L2 dominance underscored L1 skills that are resilient and vulnerable to increases in L2 proficiency. PMID:23869741

2010-01-01
Caregivers of people living with HIV (PLH) in Thailand face tremendous caregiver burden. This study examines complex ways in which caregivers’ mental health affects their levels of caregiver burden. This study uses data from 409 caregivers of PLH in northern and north-eastern Thailand. Multiple regression models were used to examine the predictors of caregiver burden. Depression was significantly associated with caregiver burden (P < 0.0001) and being HIV positive (P = 0.015). Inverse associations were observed between depression and quality of life (P < 0.0001) and caregiver burden and quality of life (P = 0.004). Social support had direct positive association with caregiver’s quality of life (P < 0.0001). Our findings underscore the complex relationship between caregiver burden, depression and HIV-status. Interventions that address the caregiver burden are urgently needed. PMID:20158549
Profiles in coping: responses to sexual harassment across persons, organizations, and cultures.
Cortina, Lilia M; Wasti, S Arzu
2005-01-01
This study explicates the complexity of sexual harassment coping behavior among 4 diverse samples of working women: (a) working-class Hispanic Americans, (b) working-class Anglo Americans, (c) professional Turks, and (d) professional Anglo Americans. K-means cluster analysis revealed 3 common harassment coping profiles: (a) detached, (b) avoidant negotiating, and (c) support seeking. The authors then tested an integrated framework of coping profile determinants, involving social power, stressor severity, social support, and culture. Analysis of variance, chi-square, and discriminant function results identified significant determinants at each of the 4 levels of this ecological model. These findings underscore the importance of focusing on whole patterns of experience--and considering influences at the level of the individual employee and multiple levels of the surrounding context--when studying how women cope with workplace sexual harassment.

The purpose of the present study was to investigate the development of college students' major selection and whether and how this choice is associated with their developing ethnic identities. Ninety ethnically diverse college students were interviewed in their first, sophomore, and senior years. Mixed-method analyses revealed 5 theoretically consistent pathways of how students configured their ethnic identities and majors over time: low awareness, consciousness-raised, high awareness, integrating, and compartmentalized. These pathways were differentially related to students' ethnicities and majors, suggesting that students' identity experiences are moderated by their chosen majors. The results of this study underscore the contribution of a longitudinal, life-span, approach to identity development for understanding the diversity in identity pathways during college. The findings also have implications for practical purposes, particularly for advising, counseling, and curriculum development.

This 3-wave longitudinal study examined the mental health consequences of the Israel-Gaza 2008-2009 war among young Israeli civilians. Data on posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and generalized anxiety disorder (GAD), and their predictors were collected during the war, and 2 and 4 months after cease fire. Results showed a sharp decline in symptom levels of PTSD, MDD, and GAD over time. Perceived social support during the war moderated the effects of immediate emotional response on subsequent levels of PTSD, MDD, and GAD. These findings underscore the importance of social support and immediate emotional response to trauma in predicting trauma-related psychopathology, and highlight the potential need for providing early care to exposed individuals exhibiting immediate and severe emotional responses.

The purpose of this study was to explore ethnic and generational influences among Chinese, Filipino, and Euro American adolescents on emotional distress and risk behaviors. Hierarchical multiple regression analyses were conducted with 216 Chinese, 387 Filipino, and 400 Euro American adolescents from the National Longitudinal Study on Adolescent Health to investigate the influence of ethnicity on depression, somatic symptoms, delinquency, and substance use; and to examine the influence of generation on the outcome variables among Chinese and Filipino American adolescents. Ethnicity predicted depression and delinquency scores, while generation within ethnic groups predicted somatic symptoms and substance use. The findings diverge from theories using acculturation as an explanatory mechanism for distress and risk behaviors and underscore the importance of examining sub-groups and generations of Asian American youth.

Little scholarship explores how adolescents’ beliefs about school and peers influence the academic outcomes of African American boys and girls. The sample included 612 African American boys (N=307, Mage=16.84) and girls (N=305, Mage=16.79). Latent class analysis (LCA) revealed unique patterns for African American boys and girls. Findings indicate that for African American boys, school attachment was protective, despite having peers who endorsed negative achievement values. Furthermore, socio-economic (SES) status was associated with higher grade point averages (GPA) for African American girls. Overall, these findings underscore the unique role of school, peer, and gendered experiences in lives of African American adolescents. PMID:26277404

Nutritional genomics, defined as the study of reciprocal interactions among nutrients, metabolic intermediates, and the genome, along with other closely related nutritional -omic fields (eg, epigenomics, transcriptomics, and metabolomics) have become vital areas of nutrition study and knowledge. Utilizing results from human metabolic research on the essential nutrient choline, this article illustrates how nutrigenetic, nutrigenomic, and inter-related -omic research has provided new insights into choline metabolism and its effect on physiologic processes. Findings from highlighted choline research are also discussed in the context of translation to clinical and public health nutrition applications. Overall, this article underscores the utility of -omic research methods in elucidating nutrient metabolism as well as the potential for nutritional -omic concepts and discoveries to be broadly applied in nutritional practice.

Flipping the switch: power, social dominance, and expectancies of mental energy change.
Egan, Patrick M; Hirt, Edward R
2015-03-01
Research suggests that high levels of interpersonal power can promote enhanced executive functioning capabilities. The present work explored whether this effect is contingent upon expectancies concerning power's downstream cognitive consequences. Study 1 showed that social dominance orientation (SDO) predicted idiosyncratic expectancies of mental energy change toward interpersonal power. Study 2 showed that SDO moderated the executive functioning changes associated with interpersonal power and that this moderation effect was contingent upon changes in perceived mental depletion. Study 3 showed that directly manipulating expectancies of mental energy change concerning interpersonal power moderated the executive functioning consequences of power and that this moderation effect was contingent upon SDO and changes in perceived mental depletion. Together, the present findings underscore the importance of expectancies and individual differences in understanding the effects of interpersonal power. © 2014 by the Society for Personality and Social Psychology, Inc.
Drosophila as a model system to study autophagy.
Zirin, Jonathan; Perrimon, Norbert
2010-12-01
Originally identified as a response to starvation in yeast, autophagy is now understood to fulfill a variety of roles in higher eukaryotes, from the maintenance of cellular homeostasis to the cellular response to stress, starvation, and infection. Although genetics and biochemical studies in yeast have identified many components involved in autophagy, the findings that some of the essential components of the yeast pathway are missing in higher organisms underscore the need to study autophagy in more complex systems. This review focuses on the use of the fruitfly, Drosophila melanogaster as a model system for analysis of autophagy. Drosophila is an organism well-suited for genetic analysis and represents an intermediate between yeast and mammals with respect to conservation of the autophagy machinery. Furthermore, the complex biology and physiology of Drosophila presents an opportunity to model human diseases in a tissue specific and analogous context.

This study examines the perception, knowledge, and help-seeking tendency toward elder mistreatment among Chinese older adults. A community-based participatory research approach was implemented to partner with the Chicago's Chinese community. A total of 39 Chinese older adults (age 60+) participated in focus group interviews. Data analysis is based on grounded theory framework. Chinese older adults mostly characterized elder mistreatment in terms of caregiver neglect and identified psychological mistreatment as the most serious form of mistreatment. Other forms included financial exploitation, physical mistreatment, and abandonment. Chinese older adults have limited knowledge of help-seeking resources other than seeking assistance from local community service centers. This study has important practical implications for health care professionals, social service agencies, and concerned family members. Our results underscore the need for research and educational initiatives as well as community awareness programs that highlight the pervasive public health issue of elder mistreatment.

Guo, Ying; Tompkins, Virginia; Justice, Laura; Petscher, Yaacov
2016-01-01
Research Findings The purpose of this exploratory study was to examine the relationship between classroom age composition and preschoolers’ vocabulary gains over an academic year and also to examine whether these relations were moderated by classroom quality. In this study (N = 130 children in 16 classrooms representing a subset of all children enrolled in these classrooms), results showed a significant cross-level interaction between classroom age composition and children’s age, suggesting positive effects of greater variance in classroom age composition for younger but not older children. The interaction between behavior management (1 dimension of classroom quality) and classroom age composition was also significant, indicating that a wider distribution of classroom age composition was positively related to children’s vocabulary gains within classrooms characterized by better behavior management. Practice or Policy Findings underscore the importance of children’s social interactions with more knowledgeable conversational partners in promoting their vocabulary development and signify the need to help teachers learn how to manage children’s behaviors so as to provide a classroom that is optimal for child learning.

Against the background that crystal methamphetamine (colloquially known as "tik") is extensively used by the emerging working class Coloured youth in Cape Town, South Africa, this exploratory qualitative study was conducted to explore the experience of mothers whose children use methamphetamine. The researchers conducted one-to-one semi-structured in-depth interviews with sixteen (16) purposively selected caregivers (mothers) whose sons use methamphetamine. Interviews were recorded and simultaneously translated and transcribed. Thematic analysis was used to identify themes related to the experiences of caregivers of youth with methamphetamine problems. Findings showed that youth misbehaviour provided a context that led to feelings of shame and embarrassment. Participants also experienced personal challenges which included emotional problems, fear and self-blame. Participants also expressed family disruptions and financial drain as adverse experiences as a results of their sons' misbehaviour. The study results highlight the psychosocial challenges for caregivers of children who use methamphetamine. These findings underscore the need for effort to be directed at the development of formal support interventions for mothers of youth who are troubled with addiction.

This study was designed to look at the challenges of standardized patients while in role and to use the findings to enhance training methods. The study investigated the effect of improvisations and multiple-task performance on the ability of standardized patients to observe and evaluate another's communication behaviors and its associated mental workload. Twenty standardized patients participated in a 2 types of interview (with and without improvisations)-by-2 types of observation (passive and active) within-groups design. The results indicated that both active observations and improvisations had a negative effect on the standardized patients' ability to observe the learner, missing more than 75% of nonverbal behaviors during active improvisational encounters. Moreover, standardized patients experienced the highest mental demand during active improvisational encounters. The findings suggest that the need to simultaneously portray a character and assess a learner may negatively affect the ability of standardized patients to provide accurate evaluations of a learner, particularly when they are required to improvise responses, underscoring the need for specific and targeted training.

We examined different forms of victimization experiences in relation to psychopathic features and whether these associations differed in boys and girls among 4855 Finnish school adolescents aged 15-16 years. Psychopathic features were measured with the Antisocial Process Screening Device- Self Report (APSD-SR). Victimization was assessed with questions about violent and abusive experiences across lifetime and within the last 12 months. Results from linear regression analysis showed that victimization was significantly associated with higher APSD-SR total scores, more strongly in girls than boys. Recent (12-month) victimization showed significance in the relationship between victimization and psychopathic features; especially recent sexual abuse and parental corporal punishment were strong determinants of higher APSD-SR total scores. The present study demonstrates novel findings on how severe victimization experiences relate to psychopathic features in community youth, especially in girls. The findings underscore the need for comprehensive evaluation of victimization experiences when psychopathic features are present in youth. Copyright © 2016 Elsevier Ltd. All rights reserved.
Parenting stress among child welfare involved families: Differences by child placement.
Rodriguez-JenKins, Jessica; Marcenko, Maureen O
2014-11-01
The intersection of parenting stress and maltreatment underscores the importance of understanding the factors associated with parenting stress among child welfare involved families. This study takes advantage of a statewide survey of child welfare involved families to examine parent and child characteristics and concrete resources, in relation to parenting stress. Separate multivariate analyses were conducted by placement status given the difference in day-to-day parenting responsibilities for families receiving in-home supervision compared to those whose children are in out-of-home care. Across both groups, parenting stress was predicted by child mental health, a finding with critical implications for intervention to this vulnerable group of families. Parent mental health also predicted parenting stress for the in-home group and food insecurity predicted parenting stress in the out-of-home group. Findings confirm that stress varies by context and that a multi-dimensional framework, considering both psychosocial and concrete resources, is required to capture contributors to parenting stress.

This study examines the associations between alcohol marketing strategies, alcohol education including knowledge about dangers of alcohol and refusal of alcohol, and drinking prevalence, problem drinking, and drunkenness. Analyses are based on the Global School-Based Student Health Survey (GSHS) conducted in Zambia (2004) of students primarily 11 to 16 years of age (N = 2257). Four statistical models were computed to test the associations between alcohol marketing and education and alcohol use, while controlling for possible confounding factors. Alcohol marketing, specifically through providing free alcohol through a company representative, was associated with drunkenness (AOR = 1.49; 95% CI: 1.09-2.02) and problem drinking (AOR = 1.41; 95% CI: 1.06-1.87) among youth after controlling for demographic characteristics, risky behaviors, and alcohol education. However, alcohol education was not associated with drunkenness or problem drinking. These findings underscore the importance of restricting alcohol marketing practices as an important policy strategy for reducing alcohol use and its dire consequences among vulnerable youth.

Bridges to nowhere: hosts, migrants, and the chimera of social capital in three African cities.
Madhavan, Sangeetha; Landau, Loren B
2011-01-01
Interest in migrant social networks and social capital has grown substantially over the past several decades. The relationship between “host” and “migrant” communities remains central to these scholarly debates. Recently urbanized cities in Africa, which include large numbers of “native-born” or internal migrants, challenge basic presumptions about host/migrant distinctions informing many of these discussions. Using comparable survey data from Johannesburg, Maputo, and Nairobi, we examine 1) the nature of social connectedness in terms of residence and nativity characteristics; and 2) the relationship between residence and nativity characteristics and three measures of trust within and across communities. Our findings suggest that the host/migrant distinction may not be particularly revealing in African cities where domestic mobility, social fragmentation and the absence of bridging institutions result in relatively low levels of trust both within and across communities. These findings underscore the need for new concepts to study “communities of strangers” and how people strategize their social mobility in urban contexts.

Since Caenorhabditis elegans was chosen as a model organism by Sydney Brenner in 1960's, genetic studies in this organism have been instrumental in discovering the function of genes and in deciphering molecular signaling network. The small size of the organism and the simple nervous system enable the complete reconstruction of the first connectome. The stereotypic developmental program and the anatomical reproducibility of synaptic connections provide a blueprint to dissect the mechanisms underlying synapse formation. Recent technological innovation using laser surgery of single axons and in vivo imaging has also made C. elegans a new model for axon regeneration. Importantly, genes regulating synaptogenesis and axon regeneration are highly conserved in function across animal phyla. This mini-review will summarize the main approaches and the key findings in understanding the mechanisms underlying the development and maintenance of the nervous system. The impact of such findings underscores the awesome power of C. elegans genetics.
Patients of doctors further from medical school graduation have poorer outcomes.

There is an apparent contradiction between the findings of studies indicating that patient outcomes are better when physicians have a greater volume of practice and those that find outcomes to be worse with increased time since training, which implies greater volume. This study was designed to estimate the adjusted relationships between physicians' characteristics, including recent practice volume and time since medical school graduation, and patient outcomes. This is a retrospective observational study based on all Pennsylvania hospitalisations over 7 years for acute myocardial infarction, congestive heart failure, gastrointestinal haemorrhage, hip fracture and pneumonia. It refers to 694 020 hospitalisations in 184 hospitals attended by 5280 internists and family physicians. Patient severity of illness at admission and in-hospital mortality, hospital location and volume, and the physician's recent practice volume, time since medical school graduation, board certification, and citizenship or medical school location were analysed. After adjustment, recent practice volume did not have a statistically significant association with in-hospital mortality for all of the conditions combined. By contrast, each decade since graduation from medical school was associated with a 4.5% increase in relative risk for patient mortality. Recent practice volume does not mitigate the increase in patient mortality associated with physicians' time since medical school graduation. These findings underscore the need to finds ways to support and encourage learning. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.
Field of Study in College and Lifetime Earnings in the United States
Kim, ChangHwan; Tamborini, Christopher R.; Sakamoto, Arthur
2016-01-01
Our understanding about the relationship between education and lifetime earnings often neglects differences by field of study. Utilizing data that matches respondents in the Survey of Income and Program Participation to their longitudinal earnings records based on administrative tax information, we investigate the trajectories of annual earnings following the same individuals over 20 years and then estimate the long-term effects of field of study on earnings for U.S. men and women. Our results provide new evidence revealing large lifetime earnings gaps across field of study. We show important differences in individuals’ earnings trajectories across the different stages of the work-life by field of study. In addition, the gaps in 40-year (i.e., ages 20 to 59) median lifetime earnings among college graduates by field of study are larger, in many instances, than the median gap between high school graduates and college graduates overall. Significant variation is also found among graduate degree holders. Our results uncover important similarities and differences between men and women with regard to the long-term earnings differentials associated with field of study. In general, these findings underscore field of study as a critical dimension of horizontal stratification in educational attainment. Other implications of the empirical findings are also discussed.

The interpersonal context of client motivational language in cognitive-behavioral therapy.
Sijercic, Iris; Button, Melissa L; Westra, Henny A; Hara, Kimberley M
2016-03-01
Previous research has found that client motivational language (especially arguments against change or counterchange talk; CCT) in early therapy sessions is a reliable predictor of therapy process and outcomes across a broad range of treatments including cognitive-behavioral therapy (CBT). Existing studies have considered the general occurrence of CCT, but the present study differentiated 2 types of CCT in early CBT sessions for 37 clients with generalized anxiety disorder: (a) statements that are uttered to express ambivalence regarding change versus (b) statements that are intended to oppose the therapist or therapy. Two process coding systems were used to accomplish this differentiation. Findings indicated that a higher number of CCT statements that occurred in the presence of resistance (opposition to the therapist or therapy) were a substantive and consistent predictor of lower homework compliance and poorer outcomes, up to 1 year posttreatment. Moreover, when both types of CCT were considered together, only opposition CCT was related to outcomes, and ambivalent CCT was not significantly predictive of proximal and distal outcomes. These findings suggest that the interpersonal context in which CCT statements occur may be critically important to their predictive capacity. More broadly, the findings of this study have implications for the future study of client motivational language and underscore the clinical importance of detecting opposition CCT.

We summarized the neuropathologic findings in 60 cetaceans stranded along the Italian coastline from 2002 to 2014. The following neuropathologic changes were detected in 45% (27/60) of animals: nonsuppurative meningo-encephalitides (30%, 18/60), nonspecific lesions (12%, 7/60), suppurative encephalitis (2%, 1/60), and neoplasm (2%, 1/60). No histologic lesions were found in 47% (28/60) of the specimens. Five (8%, 5/60) samples were unsuitable for analysis. Analysis with PCR detected Brucella spp., morbillivirus, and Toxoplasma gondii infection in one, six, and seven individuals, respectively. Immunohistochemical analysis confirmed positivity for morbillivirus and for T. gondii infection in three cases each. No evidence of the scrapie-associated prion protein PrPSc was detected. Our findings underscore the importance of an adequate surveillance system for monitoring aquatic mammal pathologies and for protecting both animal and human health.
Spatial ability mediates the gender difference in middle school students' science performance.
Ganley, Colleen M; Vasilyeva, Marina; Dulaney, Alana
2014-01-01
Prior research has demonstrated a male advantage in spatial skills and science achievement. The present research integrated these findings by testing the potential role of spatial skills in gender differences in the science performance of eighth-grade students (13-15 years old). In (N = 113), the findings showed that mental rotation ability mediated gender differences in physical science and technology/engineering test scores. In (N = 73,245), science performance was examined in a state population of eighth-grade students. As in , the results revealed larger gender differences on items that showed higher correlations with mental rotation. These findings underscore the importance of considering spatial training interventions aimed at reducing gender differences in the science performance of school-aged children. © 2014 The Authors.

The effect of supporting electrolytes and temperature on the behavior of dications and radical cations of carotenoids is studied. Cyclic voltammograms (CVs) of canthaxanthin (I) at 23 and {minus}25 C show that Car{sup sm{underscore}bullet+} of I has similar stability during the time of the CV scan, when using tetrabutylammonium perchlorate (TBAPC), tetrabutylammonium tetrafluoroborate (TBATFB), or tetrabutylammonium hexafluorophosphate (TBAHFP) as supporting electrolyte. However, the stability of Car{sup 2+} decreases when using TBAPC or TBATFB; {beta}-carotene (II) shows similar behavior. The CV of I at {minus}25 C shows a strong cathodic wave (wave 6) near {minus}0.15 V (vs Ag) with an intensitymore » about half that of the neutral oxidation wave when TBAPC or TBATFB is the supporting electrolyte. When TBAHFP is used, wave 6 (ca. {minus}0.05 V vs Ag) is ca. 8 times weaker than when TBAPC or TBATFB is used. This wave results from the reduction of a species that may be a decay product of Car{sup 2+} of I. Results show that these electrolytes commonly used in electrochemical studies may affect the studied systems to different extents. In simultaneous bulk electrolysis (BE) and optical absorption spectroscopic measurements, the absorption band of Car{sup 2+} of I in the presence of 0.1 M TBAHFP can be observed by lowering the BE temperature to {minus}20 C. In the presence of 0.1 M TBAPC or TBATFB, this band is not observed, even at {minus}50 C. Isomerization of neutral I (as shown by HPLC and its blue absorption band shift) is observed only when the Car{sup 2+} absorption band is absent during BE. This observation, along with an increase of the neutral absorption band after stopping BE, suggests that the equilibrium Car + Car{sup 2+} {r{underscore}equilibrium} 2Car{sup {sm{underscore}bullet}+} is shifted to the left because Car{sup 2+} decays more quickly than Car{sup {sm{underscore}bullet}+} in the presence of electrolyte and this is a major path for formation of cis neutral species from cis Car{sup {sm{underscore}bullet}+}. The optical absorption of Car{sup 2+} of I at 18 C in the presence of 0.1 M TBAHFP is obtained, which suggests that Car{sup 2+} of I is not as unstable at room temperature in the presence of TBAHFP as was thought before.« less
Education and mortality among older adults in China.
Luo, Ye; Zhang, Zhenmei; Gu, Danan
2015-02-01
This study examines the relationship between education and mortality, its underlying mechanisms, and its gender and age variations among older adults in China, using data from the 2002 to 2011 waves of the Chinese Longitudinal Healthy Longevity Survey. There is an inverse relationship between education and mortality risk. The relationship is explained in full by each of the three mechanisms: other socioeconomic attainments, social relationships and activities, and health status, and partially by physical exercise. In addition, primary education has a stronger effect on mortality for men than for women and the effect of education is stronger for the young old than for the oldest old. These findings underscore the importance of national and subpopulation contexts in understanding the relationship between education and mortality. Copyright © 2014 Elsevier Ltd. All rights reserved.
Trajectories of charged dust grains in the cometary environment

Using a simple model of the particles and fields environment of a comet, the trajectories of the smallest (micron- and submicron-sized) dust grains that are expected to be released from a cometary nucleus are calculated. It is shown that electromagnetic forces play a crucial role in the dynamics of these particles. The present calculations indicate not only the asymmetry of the sunward dust envelopes that have been suggested earlier by other authors, but they also indicate the possible existence of wavy dust features far down the tail, reminiscent of the peculiar wavy dust feature observed in the dust tail of Comet Ikeya-Seki 1965f. The importance of these findings in studying the lower end of the cometary dust mass spectrum during the forthcoming fly-by missions to Comet Halley is underscored.
Exposure to child abuse and risk for mental health problems in women.
Schneider, Renee; Baumrind, Nikki; Kimerling, Rachel
2007-01-01
Risk for adult mental health problems associated with child sexual, physical, or emotional abuse and multiple types of child abuse was examined. Logistic regression analyses were used to test study hypotheses in a population-based sample of women (N = 3,936). As expected, child sexual, physical, and emotional abuse were independently associated with increased risk for mental health problems. History of multiple types of child abuse was also associated with elevated risk for mental health problems. In particular, exposure to all three types of child abuse was linked to a 23-fold increase in risk for probable posttraumatic stress disorder (PTSD). Findings underscore relations between child emotional abuse and adult mental health problems and highlight the need for mental health services for survivors of multiple types of child abuse.
Recovery-oriented perceptions as predictors of reincarceration.
De Leon, George; Melnick, Gerald; Cao, Yan; Wexler, Harry K
2006-07-01
The present prospective study explored whether a specific class of client subjective assessments predicts later recovery. Measures of client perceptions of self-change in substance abusers were obtained a year after release from a prison-based therapeutic community. Analyses assessed the contribution of these perceptions-along with motivation, age, and risk index of social deviancy-in predicting reincarceration at 3-year follow-up. Results showed that two factors (Individual Growth and Socialization) significantly differentiated reincarceration and nonreincarceration at 1-year postrelease and significantly predicted reincarceration at 3-year follow-up. Findings underscore the relevance of perceptions of self-change early in recovery to later recovery behaviors. Research on recovery factors needs a uniform assessment protocol, which organizes client perceptions, beliefs, and attributions in accordance with a recovery stage framework.

Pancreatic cancer is a the four leading cause of cancer related deaths and is adisease with poor prognosis. It is refractory to standard chemotherapeutic drugs or to novel treatment modalities, making it imperative to find new treatments. In this study, using both primary and metastatic pancreatic cancer cell lines, we have demonstrated that the flavonoid myricetin induced pancreatic cancer cell death in vitro via apoptosis, and caused a decrease in PI3 kinase activity. In vivo, treatment of orthotopic pancreatic tumors with myricetin resulted in tumor regression and decreased metastatic spread. Importantly, myricetin was non-toxic, both in vitro and in vivo, underscoring its use as a therapeutic agent against pancreatic cancer. PMID:21676539
In Search of Culturally Appropriate Autism Interventions: Perspectives of Latino Caregivers.
DuBay, Michaela; Watson, Linda R; Zhang, Wanqing
2018-05-01
Most evidence-based autism spectrum disorder (ASD) interventions are tested with primarily White, mid-upper class, English-speaking populations, despite the increase in Latino children with ASD in early intervention programs throughout the United States. Unfortunately, interventions that are incongruent with a target population's culture may be relatively ineffective. This mixed-methods study explored how culturally appropriate, feasible, and acceptable Latino caregivers perceived intervention models, strategies, and targets. Survey data were compared for 28 Latino and 27 non-Latino White parents of young children with ASD. Further, 20 Latino caregivers participated in focus groups to describe their challenges, perspectives and preferences for intervention strategies and models, and unmet needs from providers. These findings underscore the need for culturally modified interventions for Latino children and families.

In this cross-sectional study, main and moderated relationships between 5 job stressors and alcohol consumption, drug use, and depression were examined using data from a community sample of 583 young adults (mean age = 23.68 years). Analyses revealed a few direct associations between high job boredom, low skill variety, and low autonomy and depression measures and heavy alcohol use. There were no direct relationships between job stress and binge drinking, alcohol consumption, drug use, or heavy drug use. In a few cases, job stress-outcome relationships were moderated by intrinsic job motivation or gender. The findings supported a specificity-of-effects hypothesis and underscored the need for examining the processes linking occupational stress to substance use and depression.

Results suggest that soil organic carbon is lost when relatively undisturbed catchments are converted for agriculture, and that when non-drained cropland catchments are restored, CH4 fluxes generally are not different than the pre-restoration baseline. Conversely, when drained cropland catchments are restored, CH4 fluxes are noticeably higher. Consequently, it is important to consider the type of wetland restoration (drained, non-drained) when assessing restoration benefits. Results also suggest that elevated N2O fluxes from cropland catchments likely would be reduced through restoration. The overall variability demonstrated by this study was consistent with findings of other wetland investigations and underscores the difficulty in quantifying the GHG balance of wetland systems.
MATERNAL CHRONOLOGICAL AGE, PRENATAL AND PERINATAL HISTORY, SOCIAL SUPPORT, AND PARENTING OF INFANTS
Bornstein, Marc H.; Putnick, Diane L.; Suwalsky, Joan T. D.; Gini, Motti
2018-01-01
The role of maternal chronological age in prenatal and perinatal history, social support, and parenting practices of new mothers (N = 335) was examined. Primiparas of 5-month-old infants ranged in age from 13 to 42 years. Age effects were zero, linear, and nonlinear. Nonlinear age effects were significantly associated up to a certain age with little or no association afterward; by spline regression, estimated points at which the slope of the regression line changed were 25 years for prenatal and perinatal history, 31 years for social supports, and 27 years for parenting practices. Given the expanding age range of first-time parents, these findings underscore the importance of incorporating maternal age as a factor in studies of parenting and child development. PMID:16942495

Purpose Patient navigation is increasingly employed to guide patients through cancer treatment. We assessed the elements of navigation that promoted patients’ involvement in treatment among patients with breast and colorectal cancer that participated in a navigation study. Methods We conducted qualitative analysis of 28 audiotaped and transcribed semi-structured interviews of navigated and un-navigated cancer patients. Results Themes included feeling emotionally and cognitively overwhelmed and desire for a strong patient-navigator partnership. Both participants who were navigated and those who were not felt that navigation did or could help address their emotional, informational, and communicational needs. The benefits of logistical support were cited less often. Conclusions Findings underscore the salience of personal relationships between patients and navigators in meeting patients’ emotional and informational needs. PMID:24890503

Motivated by experiments on La 2ZnIrO 6 and La 2MgIrO 6, we study the magnetism of spin-orbit coupled jeff = 1/2 iridium moments on the three-dimensional geometrically-frustrated face-centered cubic lattice. The symmetry-allowed nearest-neighbor interaction includes Heisenberg, Kitaev, and symmetric off-diagonal exchange. Using Luttinger-Tisza and Monte Carlo simulations, we find a rich variety of orders, including collinear A-type antiferromagnetism, collinear stripe order with moments along the {111}-direction, and incommensurate non-coplanar spirals, and determine their magnetic ordering transition temperatures. We argue that thermodynamic data on these iridates underscore the presence of a dominant Kitaev exchange, and suggest a possible resolution to themore » puzzle of why La 2ZnIrO 6, but not La 2MgIrO 6, exhibits 'weak' ferromagnetism.« less

Generalized anxiety and depression symptoms may be associated with poorer social outcomes among children with Autism Spectrum Disorder (ASD) without intellectual disability. The goal of this study was to examine whether generalized anxiety and depression symptoms were associated with social competence after accounting for IQ, age, and gender in typically developing children and in children with ASD. Results indicated that for the TD group, generalized anxiety and depression accounted for 38% of the variance in social competence and for children with ASD, they accounted for 29% of the variance in social competence. However, only depression accounted for a significant amount of the variance. The findings underscore the importance of assessing the social impact of internalizing symptoms in children with ASD.

The relationship between rural-to-urban migration and the spread of HIV is well described, although most studies focus on sexual risk behaviors among rural-to-urban migrants at the urban destination areas. Few studies have examined the sexual risk behaviors of migrants who have returned from urban areas to their rural homes (“return migrants”) in comparison with those of local rural residents who have never migrated to cities (“non-migrants”). This study examines the potential association between rural-to-urban migration and sexual risk behaviors by comparing sexual risk behaviors between 553 return migrants and 441 non-migrants from same rural communities in China. Findings reveal that, after controlling for sociodemographic characteristics, return migrants in rural areas had higher levels of sexual risk, including unprotected sex, than non-migrants. Among return migrants, sexual risk behaviors were associated with age, gender, marital status, and number of different jobs they had previously held in the cities. These findings underscore the importance for HIV/AIDS education and prevention efforts targeting the migrant population in urban destinations as well as the return migrant population in rural areas.

This study examined the dyadic association of terror attack survivors’ and spouses’ internal resources, tendency to forgive (self, others,and situational forgiveness), self-esteem, and the external resource of social support, as associated with victims’ and spouses’ posttraumatic stress disorder (PTSD) symptoms, using the actor–partner interdependence model. Based on lists by the One Family organization in Israel, 108 couples participated in the study. The study results demonstrate that in the dyad relationship, survivors’ tenden cyto forgive others and social support relate both to survivors’ decreased levels of PTSD symptom severity (β = −.20, p = .021;β =−.55 p < .001) and spouses’ decreased levels of PTSD symptom severity (β =−.21, p = .015; β =−.27, p = . 004), whereas spouses’ self-esteem relates to both spouses’ and survivors’ decreased levels of PTSD symptom severity (β =−.57, p < .001; β =−.14, p = .041).The findings underscore the role of the survivor–spouse unit by highlighting the dyad relationship of internal and external resources as associated with both survivors’ and spouses’ PTSD symptoms. Theoretical and clinical implications of the findings are discussed.

Objective To analyze corporate governance arrangements and quality and financial performance outcomes among large multi-facility nursing home corporations (chains) that pursue stakeholder value (profit maximization) strategies. Study Design To establish a foundation of knowledge about the focal phenomenon and processes, we conducted an historical (1993–2005) case study of one of the largest chains (Sun Helathcare Inc.) that triangulated qualitative and quantitative data sources. Data Sources Two main sets of information were compared: (1) corporate sources including Sun's Security Exchange Commission (SEC) Form 10-K annual reports, industry financial reports, and the business press; and (2) external sources including, legal documents, press reports, and publicly available California facility cost reports and quality data. Principal Findings Shareholder value was pursued at Sun through three inter-linked strategies: (1) rapid growth through debt-financed mergers; (2) labor cost constraint through low nurse staffing levels; and (3) a model of corporate governance that views sanctions for fraud and poor quality as a cost of business. Conclusions Study findings and evidence from other large nursing home chains underscore calls from the Institute of Medicine and other bodies for extended oversight of the corporate governance and performance of large nursing home chains.

Loneliness has been repeatedly associated with sleep problems; however, there is a dearth of research examining the prospective relationship between insomnia and loneliness, as well as this association controlling for other psychiatric symptoms. This study evaluated the cross-sectional and prospective relationship between insomnia and loneliness using six samples: 666 undergraduates; 2785 Army recruiters; 208 adults with a history of suicidality and/or depression; 343 adult psychiatric outpatients; 326 young adults at elevated suicide risk; and 183 undergraduates. A meta-analysis also was conducted to examine the magnitude of the relationship between insomnia and loneliness across the six studies. More severe insomnia symptoms were significantly associated with greater feelings of loneliness while accounting for some (e.g., anxiety, nightmares) but not all (i.e., depression) psychiatric covariates. Findings underscore the strength of the association between insomnia and loneliness and suggest that depression may account for this relationship. Additional studies are needed to further establish the temporal relationship between these variables, delineate the role of depression in the association between insomnia and loneliness, and test whether insomnia may confer unique risk for subsequent loneliness.

Human child survival depends on adult investment, typically from parents. However, in spite of recent research advances on kin influence and birth order effects on human infant and child mortality, studies that directly examine the interaction of kin context and birth order on sibling differences in child mortality are still rare. Our study supplements this literature with new findings from large-scale individual-level panel data for three East Asian historical populations from northeast China (1789-1909), northeast Japan (1716-1870), and north Taiwan (1906-1945), where preference for sons and first-borns is common. We examine and compare male child mortality risks by presence/absence of co-resident parents, grandparents, and other kin, as well as their interaction effects with birth order. We apply discrete-time event-history analysis on over 172,000 observations of 69,125 boys aged 1-9 years old. We find that in all three populations, while the presence of parents is important for child survival, it is more beneficial to first/early-borns than to later-borns. Effects of other co-resident kin are however null or inconsistent between populations. Our findings underscore the importance of birth order in understanding how differential parental investment may produce child survival differentials between siblings.

Until recently, the literature that addressed the phenomenon of mixed-orientation relationships, in which the female partner is straight and the male partner is non-straight, has focused mainly on the men's perspective. Most of the studies have employed a pessimistic tone, underscoring the obstacles faced by each of the partners. This study was designed to understand how women of mixed-orientation relationships construct their reality within such a relationship, focusing on elements that assist them in maintaining those relationships. Based on the phenomenological paradigm, in-depth interviews with eight women in mixed-orientation relationships were conducted. The findings indicate that in order to adapt to their newly constructed reality, women reframe various individual, marital, and social aspects in their lives. Those reframing processes constituted a point of departure to developing a conceptual model, which outlines the journey to reality reconstruction among women in mixed-orientation relationships.

The goal of this study was to analyze the impact of the 80-hour work week on the emergency operative experience of surgical residents. A 2-year retrospective comparison of the operative experience in emergency abdominal procedures of postgraduate year 4 and 5 residents in a city hospital before (group 1) and after (group 2) duty hour restriction. There was no difference between groups in the mean number of procedures performed as the primary surgeon, but group 2 showed a 40% decrease in technically advanced procedures with a 44% increase in basic procedures. The study also demonstrated a 54% decrease in the operative volume as first assistant. Operative continuity of care by residents decreased from 60% to 26% of cases. The ACGME regulatory environment is adversely affecting the emergency operative experience of surgical residents. Our findings underscore the need to develop alternative methods to augment the residents' operative experience.
Correlates of exchanging sex for drugs or money among women who use crack cocaine.

This study examined the correlates of trading sex for drugs or money among women who use crack cocaine. Using baseline data (n = 669) from a woman-focused HIV intervention study among African American women who use crack cocaine, we conducted logistic regression analysis to examine the odds of trading sex associated with distal and proximal factors. The results indicate that heavier crack use, homelessness, and unemployment are associated with trading sex. In addition, childhood abuse is associated with trading sex and this relationship is, in part, mediated by psychological distress. This suggests that distal factors may underlie the relationship between current variables and sex trading. These findings underscore the importance for public health interventions to address both distal and proximal factors that contribute to and/or co-occur with women's drug use which, in turn, may affect their HIV risk and overall well-being.

This study examines correlates of in-law conflict with intimate partner violence (IPV) against pregnant women in a cohort of Chinese pregnant women who visited antenatal clinics in Hong Kong. This was a territory-wide, cross-sectional study of 3,245 pregnant women recruited from seven hospitals in Hong Kong. Participants were invited to complete the Chinese Abuse Assessment Screen and a demographic questionnaire. About 9% of the pregnant women reported having been abused by their partners in the preceding year. In-law conflict was the characteristic most significantly associated with preceding-year abuse against pregnant women, after controlling for covariates. Findings underscore the need to obtain information on in-law conflict as a risk factor for IPV. In-law conflict should be included in the assessment of risk for IPV. For the prevention of IPV, family-based intervention is needed to work with victims as well as in-laws.

Recent studies have underscored physiological and pathophysiological roles for the tryptophan-degrading enzyme indolamine 2,3-dioxygenase (IDO) in immune counterregulation. However, IDO was first recognized as an antimicrobial effector, restricting tryptophan availability to Toxoplasma gondii and other pathogens in vitro. The biological relevance of these findings came under question when infectious phenotypes were not forthcoming in IDO-deficient mice. The recent discovery of an IDO homolog, IDO-2, suggested that the issue deserved reexamination. IDO inhibition during murine toxoplasmosis led to 100% mortality, with increased parasite burdens and no evident effects on the immune response. Similar studies revealed a counterregulatory role for IDO during leishmaniasis (restraining effector immune responses and parasite clearance), and no evident role for IDO in herpes simplex virus type 1 (HSV-1) infection. Thus, IDO plays biologically important roles in the host response to diverse intracellular infections, but the dominant nature of this role—antimicrobial or immunoregulatory—is pathogen-specific.

Developmental-ecological models are useful for integrating risk factors across multiple contexts and conceptualizing mediational pathways for adolescent alcohol use; yet, these comprehensive models are rarely tested. This study used a developmental-ecological framework to investigate the influence of neighborhood, family, and peer contexts on alcohol use in early adolescence (N = 387). Results from a multi-informant longitudinal cross-lagged mediation path model suggested that high levels of neighborhood disadvantage were associated with high levels of alcohol use two years later via an indirect pathway that included exposure to delinquent peers and adolescent delinquency. Results also indicated that adolescent involvement with delinquent peers and alcohol use led to decrements in parenting, rather than being consequences of poor parenting. Overall, the study supported hypothesized relationships among key microsystems thought to influence adolescent alcohol use, and thus findings underscore the utility of developmental-ecological models of alcohol use.

Of the 114 million rural-to-urban migrants in China, most have only temporary employment in the cities. Because of their non-urban residence, they are not entitled to many benefits and services accorded to most urban dwellers. Only limited research has been conducted on the health care access and health seeking behaviors of this population. This study, based on qualitative data from in-depth interviews with 90 rural-to-urban migrants, found that migrants had limited access to regular medical services. Lack of insurance coverage, high cost, and exacting work schedules have resulted in use of unsupervised self-treatment or substandard care. Their health seeking behaviors have led to suboptimal health consequences including delayed treatment of illnesses. Findings from this study underscore the importance of reducing institutional barriers to health services and providing affordable health care to this population. PMID:18277099

This study explored effective interviewer strategies and lessons-learned based on collection of narrative data by telephone with a sub-sample of women from a population-based survey, which included sexual minority women. Qualitative follow-up, in-depth life history interviews were conducted over the telephone with 48 women who had participated in the 2009-2010 National Alcohol Survey. Questions explored the lives and experiences of women, including use of alcohol and drugs, social relationships, identity, and past traumatic experiences. Strategies for success in interviews emerged in three overarching areas: 1) cultivating rapport and maintaining connection, 2) demonstrating responsiveness to interviewee content, concerns, and 3) communicating regard for the interviewee and her contribution. Findings underscore both the viability and value of telephone interviews as a method for collecting rich narrative data on sensitive subjects among women, including women who may be marginalized.

This study examined the mentalization capabilities of children exposed to parental methamphetamine abuse in relation to symptom underreporting, mental health, and behavioral outcomes. Twenty-six school-aged children in foster care participated in this study. Mentalization was assessed using the My Family Stories Interview (MFSI), a semi-structured interview in which children recalled family stories about a happy, sad or scary and fun time. An established scale of the Trauma Symptom Checklist for Children (TSCC), a self-report measure, provided information on children's symptom underreporting. The Child Behavior Checklist (CBCL), completed by the children's foster caregivers, assessed children's mental health and behavioral outcomes. Children with higher mentalization were significantly less prone to underreport symptoms. These children had fewer mental health problems and were rated by their foster caregivers as more socially competent. The findings underscore that mentalization could be an important protective factor for children who have experienced parental substance abuse.
Why be moral? Moral identity motivation and age.
Krettenauer, Tobias; Victor, Rosemary
2017-08-01
Moral identity research to date has largely failed to provide evidence for developmental trends in moral identity, presumably because of restrictions in the age range of studies and the use of moral identity measures that are insensitive to age-related change. The present study investigated moral identity motivation across a broad age range (14-65 years, M = 33.48; N = 252) using a modified version of the Good Self-Assessment Interview. Individuals' moral identity motivation was coded and categorized as external, internal, or relationship-oriented. It was found that with age, external moral identity motivation decreased, whereas internal moral identity motivation increased. Effects of age were stronger in adolescence and emerging adulthood than in young adulthood and middle age. Findings underscore the developmental nature of the moral identity construct and suggest that moral motivation becomes more self-integrated with age.

This study examined whether diabetes-specific self-efficacy mediates the association between overprotection and distress and whether this mediation depends on glycemic control and gender. The research sample of 215 individuals with diabetes and their partners completed a measure of partners' overprotective behaviours towards the patient. Patients also completed measures of diabetes-specific self-efficacy and diabetes-related distress. Further, HbA1c values were obtained as an indication of glycemic control. Diabetes-specific self-efficacy mediated the association between overprotection by the partner and diabetes-related distress especially when glycemic control was relatively poor. Furthermore, diabetes-specific self-efficacy mediated the association between overprotection and diabetes-related distress more strongly in female than in male patients. The findings underscore the importance of studying both moderators and mediators in the association between partner behaviour and distress in patients.

Fluorescence assays are useful tools for estimating enzymatic activity. Their simplicity and manageability make them suitable for screening enzyme inhibitors in drug discovery studies. However, researchers need to pay attention to compounds that show auto-fluorescence and quench fluorescence, because such compounds lower the accuracy of the fluorescence assay systems by producing false-positive or negative results. In this study, we found that aurone compound 7, which has been reported as a histone deacetylase (HDAC) inhibitor, gave false-positive results. Although compound 7 was identified by an in vitro HDAC fluorescence assay, it did not show HDAC inhibitory activity in a cell-based assay, leading us to suspect its in vitro HDAC inhibitory activity. As a result of verification experiments, we found that compound 7 interferes with the HDAC fluorescence assay by quenching the HDAC fluorescence signal. Our findings underscore the faults of fluorescence assays and call attention to careless interpretation.

To explore predictors of knowledge of Alzheimer's disease (AD), feelings of shame if a family member were to have AD, and awareness of AD-related services among Korean American elders. Using data from 675 Korean American elders (mean age = 70.2, SD = 6.87), the study estimates hierarchical linear or logistic regression models. Greater knowledge of AD is predicted by higher levels of education and acculturation. Feelings of shame associated with family members having AD are more likely to be reported by individuals with lower levels of education, acculturation, and knowledge of AD. Those who are married have greater levels of education and acculturation, and those who have a family member with AD are more aware of AD-related services. The study findings underscore the pivotal role of education and acculturation in predicting knowledge of AD, feelings of shame, and awareness of AD-related services.
A longitudinal study of lexical development in children learning Vietnamese and English.
Pham, Giang; Kohnert, Kathryn
2014-01-01
This longitudinal study modeled lexical development among children who spoke Vietnamese as a first language (L1) and English as a second language (L2). Participants (n = 33, initial mean age of 7.3 years) completed a total of eight tasks (four in each language) that measured vocabulary knowledge and lexical processing at four yearly time points. Multivariate hierarchical linear modeling was used to calculate L1 and L2 trajectories within the same model for each task. Main findings included (a) positive growth in each language, (b) greater gains in English resulting in shifts toward L2 dominance, and (c) different patterns for receptive and expressive domains. Timing of shifts to L2 dominance underscored L1 skills that are resilient and vulnerable to increases in L2 proficiency. © 2013 The Authors.

In 2013 approximately 37,000 people were living with HIV in Ecuador (prevalence 0.4%), representing a generalized epidemic where most new infections arise from sexual interactions in the general population. Studies that examine attitudes towards people living with HIV (PLWH), individual risk perception of acquiring HIV amongst Ecuadorians, and the ways in which levels of risk perception may affect risk behaviors are lacking. This qualitative study aimed to fill this gap in the literature by investigating these issues in the rural, coastal community of Manglaralto, Ecuador, which has among the highest incidence of HIV in Ecuador. We conducted interviews with 15 patients at Manglaralto Hospital. Analysis of interview transcripts revealed widespread negative attitudes towards PLWH, prevalent risk behaviors such as multiple sex partners and lack of condom use, and low individual risk-perception of contracting HIV. These findings underscore the need for increased efforts to prevent further growth of the HIV epidemic in Ecuador.

Domestic violence is a pandemic and estimated to affect one in three women globally, in their lifetime. Marriages within blood relations in Pakistan are common. In this study a secondary analysis of Pakistan Demographic and Health Survey 2012-13 was done to study the prevalence and profile of domestic violence in the context of consanguineous marriages in Pakistan. Almost 65% of women had some kind of blood relationship with their husbands. Women having a blood relationship with husbands were more likely to report having ever been subjected to marital control behaviours, emotional and physical violence by their husbands, compared to ones without such relationship. However, these associations fail to reach statistical significance; underscoring the ubiquitous nature of marital control and violence. More effective public health education campaigns for just and equal treatment of wives by their husbands to speedily curb the scourge of domestic violence in the country are needed.

2008-07-01
Using ambulatory methods for 1 week of monitoring, this study investigated the association between smoking and situational cues in 22 smokers with post-traumatic stress disorder (PTSD) and 23 smokers without PTSD. Generalized estimating equations contrasted 1,759 smoking and 1,088 nonsmoking situations by group status controlling for multiple covariates. PTSD smokers reported higher stress and PTSD symptoms across daily activities. For all smokers, higher nicotine dependence, craving, food and caffeine consumption, and being outside were related to smoking. PTSD smokers were more likely to smoke when experiencing PTSD symptoms, anxiety, and stress. Following smoking, smokers with PTSD reported a significant reduction in negative affect. These results are consistent with previous ambulatory findings regarding mood in smokers, and underscore that in smokers with PTSD, PTSD symptom variables as well as stress and anxiety are significantly associated with ad lib smoking.
Inclusive science education: learning from Wizard

Koomen, Michele Hollingsworth
2016-06-01
This case study reports on a student with special education needs in an inclusive seventh grade life science classroom using a framework of disability studies in education. Classroom data collected over 13 weeks consisted of qualitative (student and classroom observations, interviews, student work samples and video-taped classroom teaching and learning record using CETP-COP) methods. Three key findings emerged in the analysis and synthesis of the data: (1) The learning experiences in science for Wizard are marked by a dichotomy straddled between autonomy ["Sometimes I do" (get it)] and dependence ["Sometimes I don't (get it)], (2) the process of learning is fragmented for Wizard because it is underscored by an emerging disciplinary literacy, (3) the nature of the inclusion is fragile and functional. Implications for classroom practices that support students with learning disabilities include focusing on student strengths, intentional use of disciplinary literacy strategies, and opportunities for eliciting student voice in decision making.
Spiritual disclosure between older adolescents and their mothers.
Brelsford, Gina M; Mahoney, Annette
2008-02-01
This study examines the role of spiritual disclosure within older adolescent-mother relationships. Spiritual disclosure is defined as mutual disclosure of personal religious and spiritual beliefs and practices. Three hundred 18- to 20-year-old college students and 130 of their mothers reported on spiritual disclosure in their relationships. According to both parties, greater spiritual disclosure was related to higher relationship satisfaction, greater use of collaborative conflict resolution strategies, less dysfunctional communication patterns, less verbal aggression, and increased general disclosure in mother-adolescent relationships beyond global religiousness and demographics. Spiritual disclosure also predicted unique variance in collaborative conflict resolution strategies beyond these factors and general disclosure. The findings underscore the value of attending to the interpersonal dimension of religion/spirituality. More specifically, the results suggest that spiritual disclosure is an indicator of relationship quality, one that is tied to better relationship functioning, and one that merits further attention in studies of family dynamics.

Aims The purpose of this study was to examine the prevalence and correlates of mental and emotional health factors among a sample of American Indian (Indigenous) adults diagnosed with type 2 diabetes. Methods Data are from a community-based participatory research project involving two Indigenous reservation communities. Data were collected from 218 Indigenous adults diagnosed with type 2 diabetes via in-person paper-and-pencil survey interviews. Results Reports of greater numbers of mental/emotional health problems were associated with increases in self-reported hyperglycemia, comorbid health problems, and health-impaired physical activities. Conclusions This study addresses a gap in the literature by demonstrating the associations between various mental/emotional health factors and diabetes-related health problems for Indigenous Americans. Findings underscore the importance of holistic, integrated primary care models for more effective diabetes care. PMID:24562607

Bilateral tuberculous mastoiditis (TOM) in an immunocompetent child is a very uncommon form of tuberculous infection presentation. This report shows the CT and MR imaging of bilateral tuberculous otomastoiditis consisting of aggressive signs of middle ear and mastoid involvement with bony destruction and periauricular collections with no signs of brain involvement. Differential diagnosis at pediatric age of destructive lesions such as mainly aggressive forms of histiocytosis is underscored. This form of bilateral TOM at this early age has not been described from a radiological perspective.
Inadvertent laboratory exposure to Bacillus anthracis--California, 2004.
2005-04-01
On June 9, 2004, the California Department of Health Services (CDHS) was notified of possible inadvertent exposure to Bacillus anthracis spores at Children's Hospital Oakland Research Institute (CHORI), where workers were evaluating the immune response of mice to B. anthracis. This report summarizes the subsequent investigation by CDHS and CDC, including assessment of exposures, administration of postexposure chemoprophylaxis, and serologic testing of potentially exposed workers. The findings underscore the importance of using appropriate biosafety practices and performing adequate sterility testing when working with material believed to contain inactivated B. anthracis organisms.

The predominant ..beta..-thalassemia in Sardinia is the ..beta../sup 0/ type in which no ..beta..-globin chains are synthesized in the homozygous state. The authors determined the ..beta..-thalassemia mutations in this population by the oligonucleotide-probe method and defined the chromosome haplotypes on which the mutation resides. The same ..beta../sup 39(CAG..-->..TAG)/ nonsense mutation was found on nine different chromosome haplotypes. Although this mutation may have arisen more than once, the multiple haplotypes could also be generated by crossing over and gene conversion events. These findings underscore the frequency of mutational events in the ..beta..-globin gene region.
Impact of Survivorship-Based Research on Defining Clinical Care Guidelines

The growing number of individuals living 5 or more years from cancer diagnosis underscores the importance of providing guidance about potential late treatment effects to clinicians caring for long-term cancer survivors. Late treatment effects are commonly experienced by cancer survivors, increase in prevalence with aging, produce substantial morbidity, and predispose to early mortality. Findings from survivorship research permit providers to anticipate health risks among predisposed survivors and facilitate their access to interventions to prevent, detect, or rehabilitate cancer-related morbidity. This manuscript reviews the impact that survivorship research has made in defining clinical care guidelines and the challenges that remain in developing and translating research findings into health screening recommendations that can optimize the quality and duration of survival after cancer.

Two unusual anatomic variations create a diagnostic dilemma in distal ulnar nerve compression.
Kiehn, Mark W; Derrick, Allison J; Iskandar, Bermans J
2008-09-01
Diagnosis of peripheral neuropathies is based upon patterns of functional deficits and electrodiagnostic testing. However, anatomic variations can lead to confounding patterns of physical and electrodiagnostic findings. Authors present a case of ulnar nerve compression due to a rare combination of anatomic variations, aberrant branching pattern, and FCU insertion at the wrist, which posed a diagnostic and therapeutic dilemma. The literature related to isolated distal ulnar motor neuropathy and anatomic variations of the ulnar nerve and adjacent structures is also reviewed. This case demonstrates how anatomic variations can complicate the interpretation of clinical and electrodiagnostic findings and underscores the importance of thorough exploration of the nerve in consideration for possible variations.

In science education, the use of digital technology-based learning can help students struggling with difficult concepts such as the movement of molecules. While digital learning tools hold much promise for science education, the question arises as to whether or not such technology can serve as an adequate surrogate for the teacher-student interactions that theorists like Lev Vygotsky (1978) underscored as being critical to learning. In response to such concerns, designers of digital curricula often utilize scaffolds to help students as they learn from such programs. Using a simulation designed to teach students about the concept of diffusion as an example, I examine the effect of including prompting language in the learning sequence of the simulation. The use of prompting language in digital curriculum appears to be successful because it elicits science students to reflect and metacognise about their learning, lending support to Vygotsky's (1978) ideas of teaching and learning involving outer and inner dialog. However, findings from think aloud data continue to underscore the importance of human linguistic exchange as a preferable learning paradigm.

Adolescents experience various forms of strain in their lives that may contribute jointly to their engagement in cyber aggression. However, little attention has been given to this idea. To address this gap in the literature, the present longitudinal study examined the moderating influence of peer rejection on the relationship between cyber victimization at Time 1 (T1) and subsequent cyber aggression at Time 2 (T2; 6 months later) among 261 (150 girls) 6th, 7th, and 8th graders. Our findings indicated that both peer rejection and cyber victimization were related to T2 peer-nominated and self-reported cyber aggression, both relational and verbal, after controlling for gender and T1 cyber aggression. Furthermore, T1 cyber victimization was related more strongly to T2 peer-nominated and self-reported cyber aggression at higher levels of T1 peer rejection. These results extend previous findings regarding the relationship between peer rejection and face-to-face aggressive behaviors to the cyber context. In addition, our findings underscore the importance of utilizing multiple methods, such as peer-nomination and self-report, to assess cyber aggression in a school setting.

The aim of the present study was to examine the effect of the unique characteristics of residing in security and political conflict zones on the willingness to use and on the actual abuse of psychoactive substances. The study focuses on the differences between youths residing in and outside conflict zones in Israel. The present study examines the link between the adolescents' level of psychoactive substance abuse and town size as well as the youths' level of ideological commitment and religiosity. 1032 adolescents aged 14-18 participated in the study. 595 (57%) lived in the nonconflict zones and 437 (43%) in conflict zones. The findings reveal that the level of psychoactive substance abuse among youths residing in conflict zones is significantly lower than that found among youths living outside conflict zones. Moreover, although town size and level of religiosity are linked to psychoactive substance abuse, no such link was found with the level of ideological commitment or place of residence (within or outside conflict zones). The study findings underscore the important effect of social supervision and perceived norms in the adolescents' environment with regard to their willingness to use psychoactive substances and to their actual abuse of such substances.

Abstract The deleterious effect of fructose, which is increasingly incorporated in many beverages, dairy products, and processed foods, has been described; fructose malabsorption has thus been reported in up to 2.4% of healthy subjects, leading to digestive clinical symptoms (eg, pain, distension, diarrhea). Because digestive involvement is frequent in patients with systemic sclerosis (SSc), we hypothesized that fructose malabsorption could be responsible for intestinal manifestations in these patients. The aims of this prospective study were to: determine the prevalence of fructose malabsorption, in SSc; predict which SSc patients are at risk of developing fructose malabsorption; and assess the outcome of digestive symptoms in SSc patients after initiation of standardized low-fructose diet. Eighty consecutive patients with SSc underwent fructose breath test. All SSc patients also completed a questionnaire on digestive symptoms, and a global symptom score (GSS) was calculated. The prevalence of fructose malabsorption was as high as 40% in SSc patients. We also observed a marked correlation between the presence of fructose malabsorption and: higher values of GSS score of digestive symptoms (P = 0.000004); and absence of delayed gastric emptying (P = 0.007). Furthermore, in SSc patients with fructose malabsorption, the median value of GSS score of digestive symptoms was lower after initiation of standardized low-fructose diet (4 before vs. 1 after; P = 0.0009). Our study underscores that fructose malabsorption often occurs in SSc patients. Our findings are thus relevant for clinical practice, highlighting that fructose breath test is a helpful, noninvasive method by: demonstrating fructose intolerance in patients with SSc; and identifying the group of SSc patients with fructose intolerance who may benefit from low-fructose diet. Interestingly, because the present series also shows that low-fructose diet resulted in a marked decrease of gastrointestinal clinical manifestations in SSc patients with fructose malabsorption, our findings underscore that fructose malabsorption may play a significant role in the onset of gastrointestinal symptoms in these patients. Finally, we suggest that fructose malabsorption may be due to reduced fructose absorption by enterocytes, impaired enteric microbiome, and decreased intestinal permeability. PMID:26426642

This study examined how aspects of the parenting and coparenting relationships relate to children's prosocial behavior in early childhood. Fifty-eight 2-parent families from a larger ongoing longitudinal study participated in this study. Mothers completed questionnaires that measured their use of inductive reasoning, as well as their children's prosocial behavior. Furthermore, parents and their children participated in 3 triadic interaction tasks that were coded to assess cooperative coparenting behavior. Results revealed that cooperative coparenting was positively associated with children's prosocial behavior. A significant interaction also emerged between maternal inductive reasoning and cooperative coparenting behavior. These findings underscore the important role of a cooperative coparenting subsystem in influencing children's emerging prosocial behavior, as well as highlight the association between positive parenting practices and children's prosocial development within the context of cooperative coparenting behaviors. This study demonstrates the utility of understanding family-level processes that contribute to children's prosocial development during early childhood.

The unique dimensions of perceptions of school and family contributing to depression and suicide ideation in Hong Kong adolescents were examined in two studies. In Study 1, among 327 Hong Kong Chinese female students ages 13-18, 47% reported some suicide ideation. Suicide ideation was significantly associated with depression, test anxiety, academic self-concept, and adolescents' perceived parental dissatisfaction with academic performance. The correlation between test anxiety and depression was especially high (r = .51). Study 2 examined how three different aspects of perceived family relationship were associated with depression and suicide ideation. Among 371 Hong Kong Chinese adolescents ages 14-20, 52.6% reported suicide ideation. Low levels of family cohesion and support and high levels of parent-adolescent conflict were positively related to depression and suicide ideation in both genders. Across both studies, depression mediated associations between academic- and family-related variables and suicide ideation. Findings underscore the importance of both academic and family climate in understanding depression and suicide ideation among Chinese adolescents.

Frisch and Hviid (2006) recently reported a study of variables that predicted heterosexual and homosexual marriage in a national cohort of Danish men and women. They found no evidence that older brothers increase the probability that a man will legally marry another man. They concluded that their data raise questions about the universality of the widely confirmed finding that older brothers increase the probability that a man will be sexually oriented towards other men (the fraternal birth order effect). In the present article, Frisch and Hviid's data were reanalyzed using one of the procedures that have been used in prior studies of fraternal birth order. The results showed that the sex ratio of older brothers to older sisters was significantly higher than the expected value of 106 in all four of their study groups (heterosexually married men, homosexually married men, heterosexually married women, and homosexually married women). In contrast, the sex ratio of younger brothers to younger sisters approximated 106 in all four groups. According to this analysis, the only group whose data resembled data from previous studies was the homosexually married males. The writer concluded that one cannot interpret findings about the correlates of heterosexual and homosexual marriage as if they were findings about the correlates of heterosexual and homosexual orientation, and that this is underscored by comparing the markedly different older-sibling sex ratios obtained from heterosexually married persons (in the Danish study) and those obtained from heterosexually oriented persons (in previous studies). It is unclear what implications, if any, Frisch and Hviid's findings have for the study of sexual orientation in general.

Several adult depression studies have investigated mental state decoding, the basis for theory of mind, using the Reading the Mind in the Eyes Test. Findings have been mixed, but a comprehensive study found a greater severity of depression to be associated with poorer mental state decoding. Importantly, there has yet to be a similar study of adolescent depression. Converging evidence suggests that atypical mental state decoding may have particularly profound effects for psychosocial functioning among depressed adolescent boys. Adolescent boys with major depressive disorder (MDD, n = 33) and sex-matched healthy controls (HCs, n = 84) completed structured clinical interviews, self-report measures of psychopathology and the Child Eyes Test (CET). The MDD group performed significantly better than HCs on the CET overall (p = 0.002), underscored by greater accuracy for negatively valenced items (p = 0.003). Group differences on items depicting positive (p = 0.129) and neutral mental states (p = 0.081) were nonsignificant. Enhanced mental state decoding among depressed adolescent boys may play a role in the maintenance of and vulnerability to adolescent depression. Findings and implications are discussed. Limitations of this study include a reliance on self-report data for HC boys, as well as a lack of 'pure' depression among the boys with MDD. © 2016 S. Karger AG, Basel.
Passion for a Cause: How It Affects Health and Subjective Well-Being.
St-Louis, Ariane C; Carbonneau, Noémie; Vallerand, Robert J
2016-06-01
Using the dualistic model of passion (Vallerand et al., 2003), this research investigated how harmonious passion (HP) or obsessive passion (OP) for a cause can affect volunteers' health and subjective well-being. Three studies with volunteers for local (local emergency crises and community help) and international (humanitarian missions) causes assessed physical and psychological health using cross-sectional and longitudinal designs. Study 1 (N = 108) showed that HP was positively related to satisfaction with one's involvement in the cause and unrelated to physical injuries due to cause involvement. OP was unrelated to satisfaction but positively associated with injuries. Findings were replicated in Study 2 (N = 83). Moreover, self-neglect mediated the positive and negative effects of HP and OP, respectively, on injuries. Study 3 (N = 77) revealed that HP predicted an increase in satisfaction and health over a 3-month mission. OP predicted an increase in physical symptoms and a decrease in health. Furthermore, OP before a mission was positively related to self-neglect that was positively associated with physical symptoms after a mission. OP also positively predicted rumination that was conducive to posttraumatic stress disorder. HP was unrelated to these variables. Findings underscore the role of passion for a cause in predicting intrapersonal outcomes of volunteers. © 2014 Wiley Periodicals, Inc.
Anticipating mismatches of HIT investments: Developing a viability-fit model for e-health services.
Mettler, Tobias
2016-01-01
Albeit massive investments in the recent years, the impact of health information technology (HIT) has been controversial and strongly disputed by both research and practice. While many studies are concerned with the development of new or the refinement of existing measurement models for assessing the impact of HIT adoption (ex post), this study presents an initial attempt to better understand the factors affecting viability and fit of HIT and thereby underscores the importance of also having instruments for managing expectations (ex ante). We extend prior research by undertaking a more granular investigation into the theoretical assumptions of viability and fit constructs. In doing so, we use a mixed-methods approach, conducting qualitative focus group discussions and a quantitative field study to improve and validate a viability-fit measurement instrument. Our findings suggest two issues for research and practice. First, the results indicate that different stakeholders perceive HIT viability and fit of the same e-health services very unequally. Second, the analysis also demonstrates that there can be a great discrepancy between the organizational viability and individual fit of a particular e-health service. The findings of this study have a number of important implications such as for health policy making, HIT portfolios, and stakeholder communication. Copyright © 2015.

Postgenomics drug development is undergoing major transformation in the age of multi-omics studies and drug repositioning. Rather than applications solely in personalized medicine, omics science thus additionally offers a better understanding of a broader range of drug targets and drug repositioning. Berberine is an isoquinoline alkaloid found in many medicinal plants. We report here a whole genome microarray study in tandem with proteomics techniques for mining the plethora of targets that are putatively involved in the antimicrobial activity of berberine against Escherichia coli. We found DNA replication/repair and transcription to be triggered by berberine, indicating that nucleic acids, in general, are among its targets. Our combined transcriptomics and proteomics multi-omics findings underscore that, in the presence of berberine, cell wall or cell membrane transport and motility-related functions are also specifically regulated. We further report a general decline in metabolism, as seen by repression of genes in carbohydrate and amino acid metabolism, energy production, and conversion. An involvement of multidrug efflux pumps, as well as reduced membrane permeability for developing resistance against berberine in E. coli was noted. Collectively, these findings offer original and significant leads for omics-guided drug discovery and future repositioning approaches in the postgenomics era, using berberine as a multi-omics case study.
A two-dimensional approach to relationship conflict: meta-analytic findings.
Woodin, Erica M
2011-06-01
This meta-analysis of 64 studies (5,071 couples) used a metacoding system to categorize observed couple conflict behaviors into categories differing in terms of valence (positive to negative) and intensity (high to low) and resulting in five behavioral categories: hostility, distress, withdrawal, problem solving, and intimacy. Aggregate effect sizes indicated that women were somewhat more likely to display hostility, distress, and intimacy during conflict, whereas men were somewhat more likely to display withdrawal and problem solving. Gender differences were of a small magnitude. For both men and women, hostility was robustly associated with lower relationship satisfaction (medium effect), distress and withdrawal were somewhat associated (small effect), and intimacy and problem solving were both closely associated with relationship satisfaction (medium effect). Effect sizes were moderated in several cases by study characteristics including year of publication, developmental period of the sample, recruitment design, duration of observed conflict, method used to induce conflict, and type of coding system used. Findings from this meta-analysis suggest that high-intensity conflict behaviors of both a positive and negative nature are important correlates of relationship satisfaction and underscore the relatively small gender differences in many conflict behaviors. 2011 APA, all rights reserved

The current study examined how a key component of caregiving stress processes, global mastery perceptions, changes with placing the care recipient in a nursing home or institution. We also explored the role of primary stressors in accounting for mastery changes with placement and whether characteristics of the caregiver and care recipient moderate reactions to placement. We applied multiphase growth curve models to prospective longitudinal data from 271 caregivers in the Caregiver Stress and Coping Study who experienced placement of their care recipient. Using a time-to/from-placement metric, we found that caregivers typically experienced declines in mastery preceding placement, followed by a significant increase within 1 year after placement and further increases thereafter. Corresponding changes in primary stressors (role overload) mediated the placement-related increase in mastery. Caregivers who reported more depressive symptoms and activities of daily living/instrumental activities of daily living dependencies of the care recipient were more likely to experience larger placement-related increases in mastery perceptions. Our findings suggest that placement alters psychological resources of caregivers and this effect is driven by corresponding changes in primary stressors. Findings also underscore the importance of examining change processes across salient life events and transitions.

Abstract Objective This study examined women's perceptions and reported effects of routine, primary care-based interventions to increase breastfeeding. Subjects and Methods A subsample (n=67) of participants in randomized controlled trials (RCTs) completed semistructured exit interviews at 6 months postpartum. RCT arms included the following: (a) routine pre-/postnatal lactation consultant (LC) support (LC group); (b) electronic prompts (EP) guiding providers to discuss breastfeeding during prenatal care visits (EP group); (c) a combined intervention (LC+EP group); and (d) controls. Interview transcripts were coded and analyzed in MAX.qda. Results Key findings included the following: (1) Brief, non-directive assessment of feeding via postpartum interviews focused attention upon feeding practices. When coupled with breastfeeding promotion interventions, interviews promoted breastfeeding. (2) The EP and LC interventions were complementary: EPs influenced initiation, while LCs helped overcome barriers and sustain breastfeeding. (3) Prenatal intent to feed both breastmilk and formula was associated with the greatest receptivity to study messages. Conclusions Findings underscore the need for interventions across the continuum of care. Trained LCs in prenatal/postpartum settings and prenatal care providers play important complementary roles that, when coupled with brief telephone feeding assessments, may improve breastfeeding rates.

Casual sexual relationships and experiences (CSREs) are still considered to be detrimental to the psychological well-being of youth even though findings remain inconclusive. Most studies have focused on emerging adulthood. Using a prospective design based on a representative sample of high school students in the province of Québec, we measured sexually active adolescents' (N = 2,304) psychological well-being six months after engaging in these relationships while controlling for prior well-being. We analyzed two forms of CSREs, friends with benefits (FWB) and one-night stand (ONS) relationships, as well as levels of sexual intimacy. The results show that CSREs had a small impact (small effect sizes) on subsequent psychological well-being, especially among girls; FWB relationships involving penetrative contact increased girls' psychological distress and both their alcohol and drug consumption. ONSs including sexual touching increased girls' psychological distress and their drug use. None of the CSREs influenced boys' psychological well-being. The findings underscored the importance of using caution when arguing that CSREs are detrimental or harmless to the psychological well-being of adolescents. The results also highlight the importance of taking into account gender and forms of CSREs in prevention and health interventions.
Examining deterrence of adult sex crimes: A semi-parametric intervention time series approach.

2014-01-01
Motivated by recent developments on dimension reduction (DR) techniques for time series data, the association of a general deterrent effect towards South Carolina (SC)'s registration and notification (SORN) policy for preventing sex crimes was examined. Using adult sex crime arrestee data from 1990 to 2005, the the idea of Central Mean Subspace (CMS) is extended to intervention time series analysis (CMS-ITS) to model the sequential intervention effects of 1995 (the year SC's SORN policy was initially implemented) and 1999 (the year the policy was revised to include online notification) on the time series spectrum. The CMS-ITS model estimation was achieved via kernel smoothing techniques, and compared to interrupted auto-regressive integrated time series (ARIMA) models. Simulation studies and application to the real data underscores our model's ability towards achieving parsimony, and to detect intervention effects not earlier determined via traditional ARIMA models. From a public health perspective, findings from this study draw attention to the potential general deterrent effects of SC's SORN policy. These findings are considered in light of the overall body of research on sex crime arrestee registration and notification policies, which remain controversial.

Migration dynamics, entrepreneurship, and African development: Lessons from Malawi.

2013-12-01
Using data from Malawi, this study situates the discourse on migration, entrepreneurship, and development within the context of Africa's social realities. It examines self-employment differences among three groups of migrants and corresponding group differences in agricultural and non-agricultural self-employment. International migrants are found to be more engaged in self-employment than internal-migrants. However, our results suggest that previous findings on the development-related contributions of returning migrants from the West need to be appropriately contextualized. When returnees from the West invest in self-employment, they typically shy away from Africa's largest economic sector - agriculture. In contrast, levels of self-employment, especially in agricultural self-employment, are highest among returning migrants and immigrants from other African countries, especially from those nearby. We also underscore the gendered dimensions of migrants' contribution to African development by demonstrating that female migrants are more likely to be self-employed in agriculture than male migrants. Furthermore, as human-capital increases, migrants are more likely to concentrate their self-employment activities in non-agricultural activities and not in the agricultural sector. The study concludes by using these findings to discuss key implications for policy and future research.

The present study investigates the external validity of emotional value measured in economic laboratory experiments by using a physiological indicator of stress, heart rate variability (HRV). While there is ample evidence supporting the external validity of economic experiments, there is little evidence comparing the magnitude of internal levels of emotional stress during decision making with external stress. The current study addresses this gap by comparing the magnitudes of decision stress experienced in the laboratory with the stress from outside the laboratory. To quantify a large change in HRV, measures observed in the laboratory during decision-making are compared to the difference between HRV during a university exam and other mental activity for the same individuals in and outside of the laboratory. The results outside the laboratory inform about the relevance of laboratory findings in terms of their relative magnitude. Results show that psychologically induced HRV changes observed in the laboratory, particularly in connection with social preferences, correspond to large effects outside. This underscores the external validity of laboratory findings and shows the magnitude of emotional value connected to pro-social economic decisions in the laboratory.

To describe the main anatomical variations of the celiac trunk and the hepatic artery at their origins. This was a prospective analysis of 100 consecutive computed tomography angiography studies of the abdomen performed during a one-year period. The findings were stratified according to classification systems devised by Sureka et al. and Michels. The celiac trunk was "normal" (i.e., the hepatogastrosplenic trunk and superior mesenteric artery originating separately from the abdominal aorta) in 43 patients. In our sample, we identified four types of variations of the celiac trunk. Regarding the hepatic artery, a normal anatomical pattern (i.e., the proper hepatic artery being a continuation of the common hepatic artery and bifurcating into the right and left hepatic arteries) was seen in 82 patients. We observed six types of variations of the hepatic artery. We found rates of variations of the hepatic artery that are different from those reported in the literature. Our findings underscore the need for proper knowledge and awareness of these anatomical variations, which can facilitate their recognition and inform decisions regarding the planning of surgical procedures, in order to avoid iatrogenic intraoperative injuries, which could lead to complications.

The development of the information society has led to increased use of everyday technology and changed the conditions for participation. Enabling participation in everyday life situations is an important rehabilitation goal after acquired brain injury (ABI). Identifying factors associated with individuals' experienced participation and problems therein is therefore essential. This study aimed at exploring the relationship between perceived difficulty in everyday technology use, perceived ability in the activities of daily living (ADL), and perceived participation, and participation problems in persons with ABI. Eighty-one persons with ABI participated in the study and were assessed by the Impact on Participation and Autonomy questionnaire, the Everyday Technology Use Questionnaire, and the ADL taxonomy. Findings showed that the combined model of difficulty in everyday technology (ET) use, ADL ability, and the interaction between them explained both participation in various domains of everyday life, and also overall level of perceived participation and the perceived problems. The findings underscore the importance of evaluating individuals' ability in both ET use and ADL after ABI to increase the probability of explaining these persons' participation in desired everyday life situations and, also, for rehabilitation design.

Epidemiology is the study of the distribution and determinants of disease in human populations. Over the past decade there has been considerable progress in our understanding of the fundamental descriptive epidemiology (levels of disease frequency: incidence and prevalence, comorbidity, mortality, trends over time, geographic distributions, and clinical characteristics) of the rheumatic diseases. This progress is reviewed for the following major rheumatic diseases: rheumatoid arthritis (RA), juvenile rheumatoid arthritis, psoriatic arthritis, osteoarthritis, systemic lupus erythematosus, giant cell arteritis, polymyalgia rheumatica, gout, Sjögren's syndrome, and ankylosing spondylitis. These findings demonstrate the dynamic nature of the incidence and prevalence of these conditions – a reflection of the impact of genetic and environmental factors. The past decade has also brought new insights regarding the comorbidity associated with rheumatic diseases. Strong evidence now shows that persons with RA are at a high risk for developing several comorbid disorders, that these conditions may have atypical features and thus may be difficult to diagnose, and that persons with RA experience poorer outcomes after comorbidity compared with the general population. Taken together, these findings underscore the complexity of the rheumatic diseases and highlight the key role of epidemiological research in understanding these intriguing conditions. PMID:19519924

Despite increasing attention to employment within the mental health sector, reports indicate that people with serious mental illness (SMI) continue to experience limited employment success in the province of Ontario, Canada. Research specifies that people with SMI who live in rural places are less likely than those living in urban centers to have access to satisfactory employment services or to become gainfully employed. The objective of this study was to examine access to employment from the perspectives of people with SMI, mental health and vocational service providers, and decision-makers, and to explore whether place influenced their access to work in northeastern Ontario. A qualitative case study using community-based participatory research methods was chosen to examine the experience of access to competitive employment in two northeastern Ontario communities. The cases selected for study were two geographic areas in northeastern Ontario which provided best-practice, mental health services to persons with SMI. Community-based site partners advertised and recruited participants, and a consumer advisory provided input on key stakeholders, questions, findings and the study action plan. The study findings were informed by individual and group interviews conducted with 46 individuals who resided in both rural and urban settings in the case communities, and feedback from 49 participants who attended town hall forums for presentation of study findings and development of an action plan. The qualitative data was supported by a secondary data source reporting on the employment outcomes of 4112 people with SMI who received disability income support and who resided in the case communities. Qualitative data were analyzed inductively, and categories and themes were developed. Findings were member checked with all informants and town hall participants in each case community. This article draws on the findings of a larger study and reports on the influence of place to the low employment success experienced by people with SMI who reside in the case communities; 91.3% of those receiving disability income support are unemployed, and rural residents experience higher levels of unemployment than those in urban places. Place was found to influence access to employment in five ways: by limited access to employment support services in rural places, and to recommended ratios in urban places; by the use of different models and practices that were inconsistent with best practices for people with SMI; by the lack of a plan for the implementation of employment services in the case communities; by limited use of the available, dedicated vocational resources for employment purposes; and by inadequate supports provided to persons with SMI who wish to enter the workforce. The results also underscore how people with SMI continue to be perceived negatively regarding their capacity for employment. Such stereotypical attitudes additionally contributed to employment marginalization of people with SMI from the workforce, especially in rural communities. The study highlights the influence of geography and human resources to the implementation of best practice employment services and supports for persons with SMI. Important policy implications include the need to consider place when implementing evidence-based practices in places where geography, distance and human health resources limit the communities' capacity to successfully do so. The study also underscores the need to build community capacity for supported employment, especially in rural places, in order to improve the participation of people with SMI in employment, and subsequently, to help shift the communities' thinking about their capacity for work.

This study examines sex differences in the association between migration and exposure to an urban environment and overweight, hypertension and diabetes in later life. Interviews were conducted with 3,604 adults aged 50 and older in the Mexican Family Life Survey (MxFLS). Logistic regression analyses were used to examine the association between previous migration, urban exposure, and risk of overweight, hypertension, and diabetes. Migration itself was not associated with health outcomes after controlling for urban exposure. The risk of overweight and diabetes associated with urban exposure appeared to be greater for men. Sex differences were found in the covariates that helped explain differences in health between those with high and low urban exposure. These findings underscore the need to consider heterogeneity in health by urban exposure and by sex.

We conducted a series of focus groups to explore the information needs of clinicians and consumers related to arthritis and driving. An open coding analysis identified common themes across both consumer and clinician-based focus groups that underscored the importance of addressing driving-related concerns and the challenges associated with assessing safety. The results revealed that although driving is critical for maintaining independence and community mobility, drivers with arthritis experience several problems that can affect safe operation of a motor vehicle. Findings from this study are part of a broader research initiative that will inform the development of the Arthritis and Driving toolkit. This toolkit outlines strategies to support safe mobility for people with arthritis and will be an important resource in the coming years given the aging population.

The purpose of this qualitative study was to assess the effectiveness of a disability sport unit in shaping perceptions of disability. Data from interviews, observations, and documents were collected on 87 elementary-aged students, one physical education teacher, and one teaching intern. Comparisons were drawn between fifth graders engaged in a five-week disability sport unit to fourth graders participating in their standard physical education curriculum. Findings revealed differences in the way fourth and fifth graders came to view individuals with disabilities. The results support an analysis of curriculum development that underscores the significance of the social model in positively impacting constructions of disability. Recommendations include the use of disability sports in physical education as an effective strategy for educating students in game play, knowledge of the Paralympics, and the inclusion of individuals with disabilities in a variety of sporting venues.
Attitudes of mothers toward sex education.
Block, D
1979-01-01
Data are presented on the attitudes of mothers from the entire social class spectrum toward content and timing of sex education for children (CT-Attitudes), and also toward sex education in school (S-Attitudes) in two California communities in 1969. Findings underscore the necessity to consider these two attitudinal variables separately. As a result of their separation for study purposes, it was possible to arrive at a four-fold typology or grouping of mothers: 1) CT liberals in favor, and 2) CT liberals opposed to sex education in schools, 3) CT conservatives in favor, and 4) CT conservatives opposed to school programs of sex education. It is inferred that educational planners need to pay due regard to the sentiments of all four maternal groups and all social classes in developing sex education programs for families and for school children.

This study examined professional psychological help seeking among 1,045 white American and Asian American students from 70 U.S. colleges and universities who had seriously considered attempting suicide. The authors found that Asian American college students had lower rates of professional psychological help seeking for their suicide ideation than White American college students. Guided by social network perspectives on professional psychological help seeking, the authors also tested mediators of this racial disparity. Relative to white Americans, Asian Americans were advised by fewer people (especially fewer family members) to seek professional help, which was, in turn, associated with lower rates of professional psychological help seeking for suicide ideation. These findings underscore the importance of gatekeeping as a suicide prevention strategy for Asian American college students.

This study examined the relative influences of posttraumatic stress disorder (PTSD), other psychopathology, and intimate partner alcohol and drug use on substance-related problems in U.S. veterans (242 couples, N = 484). Hierarchical regression analyses revealed that partner alcohol and drug use severity explained more variance in veteran alcohol use and drug use (20% and 13%, respectively) than did veteran PTSD, adult antisocial behavior, or depression symptoms combined (6% for veteran alcohol use; 7% for veteran drug use). Findings shed new light on the influence of relationship factors on veteran alcohol and drug use and underscore the importance of couples-oriented approaches to treating veterans with comorbid PTSD and substance abuse.

Modified Atmosphere Systems and Shelf Life Extension of Fish and Fishery Products
DeWitt, Christina A. Mireles; Oliveira, Alexandra C.M.
2016-01-01
This review aims at summarizing the findings of studies published over the past 15 years on the application of modified atmosphere (MA) systems for shelf life extension of fish and fishery products. This review highlights the importance of CO2 in the preservation of seafood products, and underscores the benefits of combining MA technology with product storage in the superchilled temperature range. It is generally accepted that MA technology cannot improve product quality and should not be utilized as a substitute for good sanitation and strict temperature control. Benefits derived from application of MA, however, can significantly impact preservation of product quality and it subsequent shelf-life. For this reason, this review is the first of its kind to propose detailed handling and quality guidelines for fresh fish to realize the maximum benefit of MA technology. PMID:28231143
Mommy markets: Racial differences in lesbians' dating preferences for women with children.
Rafalow, Matthew H; Kizer, Jessica M
2017-11-22
Recent work shows that race is a critical factor in shaping sexual identities, partner preference, and family formation, suggesting there may be racial differences in whether lesbians already have children at the time that they look for companions. In this study, we draw on a sample of 1,923 lesbians on Match.com to quantitatively test whether there are racial differences in dating preferences for women with children, underscoring implications for family inequality through racial differences in who has children when looking for a partner. We find that Blacks, Latinas, and Asians are more likely than Whites to not only have children but also be open to dating other women with children. This suggests that race differentially structures lesbians' openness to partners with children, and such preferences may be a possible mechanism for racial stratification.

Following LDEF retrieval, a number of studies were made of mechanical hardware and structure flown on the LDEF. The primary objectives are to determine the effects of long term space exposure on (1) mechanisms either used on LDEF or as part of individual experiments; (2) LDEF structural components; and (3) fasteners. Results from examination and testing of LDEF structure, fasteners, LDEF end support beam, environment exposure control canisters, experiment tray clamps, LDEF grapple fixtures, and viscous damper are presented. The most significant finding is the absence of space exposure related cold welding. The instances of seizure or removal difficulties initially attributed to cold welding were shown to have resulted from installation galling damage or improper removal techniques. Widespread difficulties encountered with removal of stainless steel fasteners underscore the need for effective thread lubrication schemes to ensure successful application of proposed orbital replacement units onboard Space Station Freedom.

The process of rural-to-urban migration in China is accelerating with increased modernization and industrialization. To address the issues of health outcomes and geographic mobility among this population, data from 4,208 rural-to-urban migrants in two major metropolitans of China were analyzed. Results indicate that average duration of migration was 4.3 years, with younger migrants being more mobile than their older counterparts. After controlling for possible confounders, increases in mobility were associated with unstable living arrangements, substandard employment conditions, suboptimal health status, inferior health-seeking behaviour, elevated level of substance use, depressive symptoms and expression of dissatisfaction with life and work. The findings in the present study underscore the need for improved living and employment conditions and increased healthcare services available to rural-to-urban migratory population.

Agarra, agarran: Evidence of early comprehension of subject-verb agreement in Spanish.
Gonzalez-Gomez, Nayeli; Hsin, Lisa; Barrière, Isabelle; Nazzi, Thierry; Legendre, Géraldine
2017-08-01
Studies across many languages (e.g., Dutch, English, Farsi, Spanish, Xhosa) have failed to show early acquisition of subject-verb (SV) agreement, whereas recent studies on French reveal acquisition by 30months of age. Using a similar procedure as in previous French studies, the current study evaluated whether earlier comprehension of SV agreement in (Mexican) Spanish can be revealed when task demands are lowered. Two experiments using a touch-screen pointing task tested comprehension of SV agreement by monolingual Spanish-speaking children growing up in Mexico City between about 3 and 5years of age. In Experiment 1, the auditory stimuli consisted of a transitive verb+pseudonoun object (e.g., agarra el micho 'he throws the micho' vs. agarran el duco 'they throw the duco'); results failed to show early comprehension of SV agreement, replicating previous findings. In Experiment 2, the same stimuli were used, with the crucial difference that the word objeto 'object' replaced all pseudonouns; results revealed SV agreement comprehension as early as 41 to 50months. Taken together, our findings show that comprehension at this age is facilitated when task demands are lowered, here by not requiring children to process pseudowords (even when these were not critical to the task). Hence, these findings underscore the importance of task-specific/stimulus-specific features when testing early morphosyntactic development and suggest that previous results may have underestimated Spanish-speaking children's competence.

The Measurement of Intelligence in the XXI Century using Video Games.
Quiroga, M A; Román, F J; De La Fuente, J; Privado, J; Colom, R
2016-12-05
This paper reviews the use of video games for measuring intelligence differences and reports two studies analyzing the relationship between intelligence and performance on a leisure video game. In the first study, the main focus was to design an Intelligence Test using puzzles from the video game. Forty-seven young participants played "Professor Layton and the curious village"® for a maximum of 15 hours and completed a set of intelligence standardized tests. Results show that the time required for completing the game interacts with intelligence differences: the higher the intelligence, the lower the time (d = .91). Furthermore, a set of 41 puzzles showed excellent psychometric properties. The second study, done seven years later, confirmed the previous findings. We finally discuss the pros and cons of video games as tools for measuring cognitive abilities with commercial video games, underscoring that psychologists must develop their own intelligence video games and delineate their key features for the measurement devices of next generation.

There is substantial evidence that both temperature and air pollution are predictors of mortality. Thus far, few studies have focused on the potential interactive effects between the thermal environment and different measures of air pollution. Such interactions, however, are biologically plausible, as (extreme) temperature or increased air pollution might make individuals more susceptible to the effects of each respective predictor. This study investigated the interactive effects between equivalent temperature and air pollution (ozone and particulate matter) in Berlin (Germany) and Lisbon (Portugal) using different types of Poisson regression models. The findings suggest that interactive effects exist between air pollutants and equivalent temperature. Bivariate response surface models and generalised additive models (GAMs) including interaction terms showed an increased risk of mortality during periods of elevated equivalent temperatures and air pollution. Cold effects were mostly unaffected by air pollution. The study underscores the importance of air pollution control in mitigating heat effects. Copyright © 2013 Elsevier Ltd. All rights reserved.

In this study, we selected individuals high and low on a measure of chronic self-destructiveness--the tendency to perform behaviors that later reduce positive consequences and increase the probability of experiencing negative ones--and attempted to differentiate high and low scorers based on a set of hypothesized antecedent and concurrent psychological, interpersonal, and behavioral correlates. Men and women were equally represented in high- and low-scoring groups. High scorers reported experiencing more interpersonal exploitation, greater depression, lower self-esteem, more externalizing attitudes, and less control in relationships than low scorers. High-scoring individuals also engaged in more frequent acts of acute self-destructiveness, including attempted suicide. A significant age covariate effect emerged: high-scoring men and women were younger than low-scoring individuals. These findings underscore the importance of studying chronic self-destructiveness within a developmental framework and suggest that issues of safety and self-care may be particularly germane to educational and clinical interventions aimed at young adults.
Regulatory observations in bioanalytical determinations.
Viswanathan, C T
2010-07-01
The concept of measuring analytes in biological media is a long-established area of the quantitative sciences that is employed in many sectors. While academic research and R&D units of private firms have been in the forefront of developing complex methodologies, it is the regulatory environment that has brought the focus and rigor to the quality control of the quantitative determination of drug concentration in biological samples. In this article, the author examines the regulatory findings discovered during the course of several years of auditing bioanalytical work. The outcomes of these findings underscore the importance of quality method validation to ensure the reliability of the data generated. The failure to ensure the reliability of these data can lead to potential risks in the health management of millions of people in the USA.
Endophytic Epichloë species and their grass hosts: from evolution to applications.
Saikkonen, Kari; Young, Carolyn A; Helander, Marjo; Schardl, Christopher L
2016-04-01
The closely linked fitness of the Epichloë symbiont and the host grass is presumed to align the coevolution of the species towards specialization and mutually beneficial cooperation. Ecological observations demonstrating that Epichloë-grass symbioses can modulate grassland ecosystems via both above- and belowground ecosystem processes support this. In many cases the detected ecological importance of Epichloë species is directly or indirectly linked to defensive mutualism attributable to alkaloids of fungal-origin. Now, modern genetic and molecular techniques enable the precise studies on evolutionary origin of endophytic Epichloë species, their coevolution with host grasses and identification the genetic variation that explains phenotypic diversity in ecologically relevant characteristics of Epichloë-grass associations. Here we briefly review the most recent findings in these areas of research using the present knowledge of the genetic variation that explains the biosynthetic pathways driving the diversity of alkaloids produced by the endophyte. These findings underscore the importance of genetic interplay between the fungus and the host in shaping their coevolution and ecological role in both natural grass ecosystems, and in the agricultural arena.

This study examines the associations between alcohol marketing strategies, alcohol education including knowledge about dangers of alcohol and refusal of alcohol, and drinking prevalence, problem drinking, and drunkenness. Analyses are based on the Global School-Based Student Health Survey (GSHS) conducted in Zambia (2004) of students primarily 11 to 16 years of age (N = 2257). Four statistical models were computed to test the associations between alcohol marketing and education and alcohol use, while controlling for possible confounding factors. Alcohol marketing, specifically through providing free alcohol through a company representative, was associated with drunkenness (AOR = 1.49; 95% CI: 1.09–2.02) and problem drinking (AOR = 1.41; 95% CI: 1.06–1.87) among youth after controlling for demographic characteristics, risky behaviors, and alcohol education. However, alcohol education was not associated with drunkenness or problem drinking. These findings underscore the importance of restricting alcohol marketing practices as an important policy strategy for reducing alcohol use and its dire consequences among vulnerable youth.

This study presents the first national level quantitative environmental justice assessment of industrial air pollution in Australia. Specifically, our analysis links the spatial distribution of sites and emissions associated with industrial pollution sources derived from the National Pollution Inventory, to Indigenous status and social disadvantage characteristics of communities derived from Australian Bureau of Statistics indicators. Our results reveal a clear national pattern of environmental injustice based on the locations of industrial pollution sources, as well as volume, and toxicity of air pollution released at these locations. Communities with the highest number of polluting sites, emission volume, and toxicity-weighted air emissions indicate significantly greater proportions of Indigenous population and higher levels of socio-economic disadvantage. The quantities and toxicities of industrial air pollution are particularly higher in communities with the lowest levels of educational attainment and occupational status. These findings emphasize the need for more detailed analysis in specific regions and communities where socially disadvantaged groups are disproportionately impacted by industrial air pollution. Our empirical findings also underscore the growing necessity to incorporate environmental justice considerations in environmental planning and policy-making in Australia.
New ways of believing or belonging: is religion giving way to spirituality?
Glendinning, Tony; Bruce, Steve
2006-09-01
In this article, the presence of alternative spirituality and practices within the general culture and their relationship to institutional religion are examined using national survey data collected as part of the 2001 Scottish Social Attitudes Survey. Alternative practices are found to divide into two groups of interests: concerns with personal well-being and interest in divination. Better-educated women are much more likely to engage with holistic practices associated with well-being; a minority of younger, less well-educated women are more likely to have found horoscopes, astrology, fortune-telling and tarot 'important in their lives'. Churchgoers find divination antithetical to religion while the use and salience of a range of holistic practices is as acceptable among churchgoers as it is among non-attenders and the secular (once allowance has been made for the connections between putatively alternative practices, gender, age and education). This underscores a focus on personal well-being rather than alternative spirituality in the consumption of holistic products and practices within the general culture. The study findings are used to assess claims for a spiritual revolution in modern Britain.

Environmental settings were defined, through an overlay process, as areas of coincidence between categories of three mapped variables - land use, surficial geology, and soil drainage characteristics. Expert judgment was used in selecting factors thought to influence sediment and nutrient concentrations in the Albemarle-Pamlico drainage area. This study's findings support the hypothesis that environmental settings defined using these three variables can explain variations in the concentration of certain sediment and nutrient constituents. This finding underscores the importance of developing watershed management plans that account for differences associated with the mosaic of natural and anthropogenic factors that define a basin's environmental setting. At least in the case of sediment and nutrients in the Albemarle-Pamlico region, a watershed management plan that focuses only on anthropogenic factors, such as point-source discharges, and does not account for natural characteristics of a watershed and the influences of these characteristics on water quality, may lead to water-quality goals that are over- or underprotective of key environmental features and to a misallocation of the resources available for environmental protection.

Recent national focus on the value of increasing our supply of indigenous, renewable energy underscores the need for reevaluating all alternatives, particularly those that are large and welldistributed nationally. This analysis will help determine how we can enlarge and diversify the portfolio of options we should be vigorously pursuing. One such option that is often ignored is geothermal energy, produced from both conventional hydrothermal and Enhanced (or engineered) Geothermal Systems (EGS). An 18-member assessment panel was assembled in September 2005 to evaluate the technical and economic feasibility of EGS becoming a major supplier of primary energy for U.S. base-load generationmore » capacity by 2050. This report documents the work of the panel at three separate levels of detail. The first is a Synopsis, which provides a brief overview of the scope, motivation, approach, major findings, and recommendations of the panel. At the second level, an Executive Summary reviews each component of the study, providing major results and findings. The third level provides full documentation in eight chapters, with each detailing the scope, approach, and results of the analysis and modeling conducted in each area.« less

This study tested a parallel two-mediator model in which the relationship between dimensions of emotional intelligence and online gaming addiction are mediated by perceived helplessness and perceived self-efficacy, respectively. The sample included 931 male adolescents (mean age = 16.18 years, SD = 0.95) from southern China. Data on emotional intelligence (four dimensions, including self-management of emotion, social skills, empathy and utilization of emotions), perceived stress (two facets, including perceived self-efficacy and perceived helplessness) and online gaming addiction were collected, and bootstrap methods were used to test this parallel two-mediator model. Our findings revealed that perceived self-efficacy mediated the relationship between three dimensions of emotional intelligence (i.e., self-management, social skills, and empathy) and online gaming addiction, and perceived helplessness mediated the relationship between two dimensions of emotional intelligence (i.e., self-management and emotion utilization) and online gaming addiction. These findings underscore the importance of separating the four dimensions of emotional intelligence and two facets of perceived stress to understand the complex relationship between these factors and online gaming addiction.

Sex differences in brain and behavior were investigated across the lifespan. Parameters include neurobehavioral measures linkable to neuroanatomic and neurophysiologic indicators of brain structure and function. Sexual differentiation of behavior has been related to organizational factors during sensitive periods of development, with adolescence and puberty gaining increased attention. Adolescence is a critical developmental period where transition to adulthood is impacted by multiple factors that can enhance vulnerability to brain dysfunction. Here we highlight sex differences in neurobehavioral measures in adolescence that are linked to brain function. We summarize neuroimaging studies examining brain structure, connectivity and perfusion, underscoring the relationship to sex differences in behavioral measures and commenting on hormonal findings. We focus on relevant data from the Philadelphia Neurodevelopmental Cohort (PNC), a community-based sample of nearly 10,000 clinically and neurocognitively phenotyped youths age 8-21 of whom 1600 have received multimodal neuroimaging. These data indicate early and pervasive sexual differentiation in neurocognitive measures that is linkable to brain parameters. We conclude by describing possible clinical implications.

Teachers’ emotions are critically important for the quality of classroom instruction, and they are key components of teachers’ psychological well-being. Past research has focused on individual differences between teachers, whereas within-teacher variation across contexts has rarely been considered. As such, the present research addresses the long-standing yet unresolved person-situation debate pertaining to the emotional experiences of teachers. In two diary studies (N = 135, 70% female, and N = 85, 28% female), we examined the role of person, academic subject, and group of students for teacher emotions; focusing on three of the most salient emotions found in teachers: enjoyment, anger, and anxiety. Findings from multi-level analysis confirmed the person specificity of enjoyment, anger, and, in particular, anxiety. In addition, underscoring the existence of within-teacher variability, findings supported that teachers’ emotions considerably varied depending on the subject and group of students taught, particularly so for enjoyment and anger. Implications of the person and context specificity of teacher emotions are discussed in relation to assessments and intervention programs aiming to improve teachers’ emotional lives in the classroom.

People who require help injecting are disproportionately vulnerable to drug-related harm, including HIV transmission. North America’s only sanctioned SIF operates in Vancouver, Canada under an exemption to federal drug laws, which imposes operating regulations prohibiting assisted injections. In response, the Vancouver Area Network of Drug Users (VANDU) launched a peer-run unsanctioned SIF in which trained peer volunteers provide assisted injections to increase the coverage of supervised injection services and minimize drug-related harm. We undertook qualitative interviews (n=23) and ethnographic observation (50 hours) to explore how this facility shaped assisted injection practices. Findings indicated that VANDU reshaped the social, structural, and spatial contexts of assisted injection practices in a manner that minimized HIV and other health risks, while allowing people who require help injecting to escape drug scene violence. Findings underscore the need for changes to regulatory frameworks governing SIFs to ensure that they accommodate people who require help injecting. PMID:23797831

How intimate partner violence (IPV), depression, and barriers to services affect Arab American women in the United States is not very well documented. This cross-sectional exploratory descriptive study examines (a) the relationship between depression and IPV and (b) whether living in the United States 10 or more years decreases barriers to reporting intimate partner violence and depression in a sample (N = 312) of Arab American women 19 years and older. Findings demonstrate significant relationships between women who were at risk for IPV and depression scores (r = .44, p < .001), and number of years living in the United States and barriers to service (r = .25, p < .001). There was a significant negative relationship between barriers to service and depression (r = -.30, p < .001), and barriers to service and IPV (r = -.23, p < .001), and number of years living in the United States and depression (r = .25, p < .001). Findings underscore the importance of screening referral and follow-up for Arab American women experiencing IPV and depression. © The Author(s) 2014.

Malaria rapid diagnostic tests (RDTs) are widely used in clinical and surveillance settings. However, the performance of most RDTs has not been characterized at parasite densities below detection by microscopy. We present findings from Uganda, where RDT results from 491 participants with suspected malaria were correlated with quantitative polymerase chain reaction (qPCR)-defined parasitemia. Compared with qPCR, the sensitivity and specificity of the RDT for Plasmodium falciparum mono-infections were 76% (95% confidence interval [CI]: 68-83%) and 95% (95% CI: 92-97%), respectively. The sensitivity of the RDT at parasite densities between 0.2 and 200 parasites/μL was surprisingly high (87%, 95% CI: 74-94%). The high sensitivity of the RDT is likely because of histidine-rich protein 2 from submicroscopic infections, gametocytes, or sequestered parasites. These findings underscore the importance of evaluating different RDTs in field studies against qPCR reference testing to better define the sensitivity and specificity, particularly at low parasite densities.

Background: This review explores the current community-based psychosocial interventions among people living with HIV/AIDS (PLWHA) across the globe. Methods: Evaluation studies were retrieved and reviewed regarding study location, characteristics of participants, study design, intervention strategies, outcome indicators, and intervention findings. Results: The 28 studies spanned a broad range of intervention strategies, including coping skills, treatment and cure, cultural activities, community involvement, knowledge education, voluntary counseling and testing, peer-group support, three-layered service provision, child-directed group intervention, adult mentoring, and support group interventions. Regardless of study designs, all studies reported positive intervention effects, ranging from a reduction in HIV/AIDS stigma, loneliness, marginalization, distress, depression, anger, and anxiety to an increase in self-esteem, self-efficacy, coping skills, and quality of life. Conclusion: Although the existing studies have limitation with regard to program coverage, intensity, scope, and methodological challenges, they underscore the importance of developing community-based interventions to promote psychosocial well-being among PLWHA. Future studies need to employ more rigorous methodology and integrate contextual and institutional factors when implementing effective interventions. PMID:25264499

This paper describes the Waste Management Facility Accident Analysis (WASTE{underscore}ACC) software, which was developed at Argonne National Laboratory (ANL) to support the US Department of Energy`s (DOE`s) Waste Management (WM) Programmatic Environmental Impact Statement (PEIS). WASTE{underscore}ACC is a decision support and database system that is compatible with Microsoft{reg_sign} Windows{trademark}. It assesses potential atmospheric releases from accidents at waste management facilities. The software provides the user with an easy-to-use tool to determine the risk-dominant accident sequences for the many possible combinations of process technologies, waste and facility types, and alternative cases described in the WM PEIS. In addition, its structure willmore » allow additional alternative cases and assumptions to be tested as part of the future DOE programmatic decision-making process. The WASTE{underscore}ACC system demonstrates one approach to performing a generic, systemwide evaluation of accident risks at waste management facilities. The advantages of WASTE{underscore}ACC are threefold. First, the software gets waste volume and radiological profile data that were used to perform other WM PEIS-related analyses directly from the WASTE{underscore}MGMT system. Second, the system allows for a consistent analysis across all sites and waste streams, which enables decision makers to understand more fully the trade-offs among various policy options and scenarios. Third, the system is easy to operate; even complex scenario runs are completed within minutes.« less
New cigarette brands with flavors that appeal to youth: tobacco marketing strategies.

2005-01-01
Tobacco manufacturers have recently introduced a proliferation of exotic brands featuring candylike flavors. We reviewed internal tobacco industry documents and patents to assess the role of flavored cigarettes in the targeting of young smokers. This research revealed the development of flavor delivery technologies hidden from consumers and public health professionals, including the use of a plastic pellet placed in the cigarette filter. These findings raise concerns as to the potential added health risks associated with using new flavored tobacco products, and they underscore the need for effective assessment and monitoring of tobacco products.

To measure the psychological and emotional effects of the September 11, 2001, terrorist attacks on the World Trade Center (WTC), Connecticut, New Jersey, and New York added a terrorism module to their ongoing Behavioral Risk Factor Surveillance System (BRFSS). This report summarizes the results of the survey, which suggest widespread psychological and emotional effects in all segments of the three states' populations. The findings underscore the importance of collaboration among public health professionals to address the physical and emotional needs of persons affected by the September 11 attacks.

Resilience and distress in Israeli society were assessed at three points in time: before and after the Israeli disengagement from Gaza, and after the second Lebanese war. A random sample of 366 Israelis was assessed for nation-related anxiety and hostility, personal resources and post-traumatic symptoms. The lowest levels of anxiety were observed at the second time point, after the disengagement. Respondents with high-resilience profiles showed lower levels of post-traumatic symptoms and higher levels of personal resources. The findings underscore Israelis' resilience and the importance of personal resources in ongoing nationally stressful situations.
Necrotizing enterocolitis: Pathophysiology from a historical context.
Hackam, David; Caplan, Michael
2018-02-01
Necrotizing enterocolitis (NEC) continues to afflict approximately 7% of preterm infants born weighing less than 1500g, though recent investigations have provided novel insights into the pathogenesis of this complex disease. The disease has been a major cause of morbidity and mortality in neonatal intensive care units worldwide for many years, and our current understanding reflects exceptional observations made decades ago. In this review, we will describe NEC from a historical context and summarize seminal findings that underscore the importance of enteral feeding, the gut microbiota, and intestinal inflammation in this complex pathophysiology.

In 2014, few health insurance plans sold in the Affordable Care Act's Federally Facilitated Marketplaces had age-dependent tobacco surcharges, possibly because of a system glitch. The 2015 tobacco surcharges show wide variation, with more plans implementing tobacco surcharges that increase with age. This underscores concerns that older tobacco users will find postsubsidy health insurance premiums difficult to afford. Future monitoring of enrollment will determine whether tobacco surcharges cause adverse selection by dissuading tobacco users, particularly older users, from buying health insurance.

Work-related amputations are serious yet preventable injuries. Workers in the manufacturing sector in particular are vulnerable to amputation injuries compared to workers in other sectors. In this study, we used a two-source capture recapture method to estimate the true number of annual work-related amputations in the Norwegian manufacturing sector for a 10-year study period (1998-2007). The two-sources utilized in this study were the Norwegian Labor Inspection Authorities Registry of Work-Related Injuries (RWI) and the Association of Norwegian Private Insurance Companies registry for occupational injuries (ANPIC). We estimated an annual incidence rate that ranged from 21/100 000 to 62/100 000 workers during the study period. Our findings indicate an undercount of amputations reported to the Norwegian Labour Inspection Authority's registry ranging from 16% to 58% during the study period. Work-related amputations remain a challenge in the Norwegian manufacturing sector. This study underscores the need of robust epidemiological surveillance infrastructure and effective interventions to prevent amputations at work.

Background . Absent adaptive, individualized dose-finding in early-phase oncology trials, subsequent 'confirmatory' Phase III trials risk suboptimal dosing, with resulting loss of statistical power and reduced probability of technical success for the investigational therapy. While progress has been made toward explicitly adaptive dose-finding and quantitative modeling of dose-response relationships, most such work continues to be organized around a concept of 'the' maximum tolerated dose (MTD). The purpose of this paper is to demonstrate concretely how the aim of early-phase trials might be conceived, not as 'dose-finding', but as dose titration algorithm (DTA) -finding. Methods. A Phase I dosing study is simulated, for a notional cytotoxic chemotherapy drug, with neutropenia constituting the critical dose-limiting toxicity. The drug's population pharmacokinetics and myelosuppression dynamics are simulated using published parameter estimates for docetaxel. The amenability of this model to linearization is explored empirically. The properties of a simple DTA targeting neutrophil nadir of 500 cells/mm 3 using a Newton-Raphson heuristic are explored through simulation in 25 simulated study subjects. Results. Individual-level myelosuppression dynamics in the simulation model approximately linearize under simple transformations of neutrophil concentration and drug dose. The simulated dose titration exhibits largely satisfactory convergence, with great variance in individualized optimal dosing. Some titration courses exhibit overshooting. Conclusions. The large inter-individual variability in simulated optimal dosing underscores the need to replace 'the' MTD with an individualized concept of MTD i . To illustrate this principle, the simplest possible DTA capable of realizing such a concept is demonstrated. Qualitative phenomena observed in this demonstration support discussion of the notion of tuning such algorithms. Although here illustrated specifically in relation to cytotoxic chemotherapy, the DTAT principle appears similarly applicable to Phase I studies of cancer immunotherapy and molecularly targeted agents.

Human child survival depends on adult investment, typically from parents. However, in spite of recent research advances on kin influence and birth order effects on human infant and child mortality, studies that directly examine the interaction of kin context and birth order on sibling differences in child mortality are still rare. Our study supplements this literature with new findings from large-scale individual-level panel data for three East Asian historical populations from northeast China (1789–1909), northeast Japan (1716–1870), and north Taiwan (1906–1945), where preference for sons and first-borns is common. We examine and compare male child mortality risks by presence/absence of co-resident parents, grandparents, and other kin, as well as their interaction effects with birth order. We apply discrete-time event-history analysis on over 172,000 observations of 69,125 boys aged 1–9 years old. We find that in all three populations, while the presence of parents is important for child survival, it is more beneficial to first/early-borns than to later-borns. Effects of other co-resident kin are however null or inconsistent between populations. Our findings underscore the importance of birth order in understanding how differential parental investment may produce child survival differentials between siblings. PMID:28781514

Bright light therapy was shown to be a promising treatment for depression during pregnancy in a recent open-label study. In an extension of this work, we report findings from a double-blind placebo-controlled pilot study. Ten pregnant women with DSM-IV major depressive disorder were randomly assigned from April 2000 to January 2002 to a 5-week clinical trial with either a 7000 lux (active) or 500 lux (placebo) light box. At the end of the randomized controlled trial, subjects had the option of continuing in a 5-week extension phase. The Structured Interview Guide for the Hamilton Depression Scale-Seasonal Affective Disorder Version was administered to assess changes in clinical status. Salivary melatonin was used to index circadian rhythm phase for comparison with antidepressant results. Although there was a small mean group advantage of active treatment throughout the randomized controlled trial, it was not statistically significant. However, in the longer 10-week trial, the presence of active versus placebo light produced a clear treatment effect (p =.001) with an effect size (0.43) similar to that seen in antidepressant drug trials. Successful treatment with bright light was associated with phase advances of the melatonin rhythm. These findings provide additional evidence for an active effect of bright light therapy for antepartum depression and underscore the need for an expanded randomized clinical trial.

Diathesis-stress models of posttraumatic stress disorder (PTSD) hypothesize that exposure to trauma may interact with individual differences in the development of PTSD. Previous studies have not assessed immediate responses to a proximate stressor, but the current "natural laboratory" study was designed to empirically test the role that individual differences in pathological narcissism may play in the development of acute anxiety symptoms among civilians facing rocket and missile fire. We assessed demographic features, trauma exposure severity, narcissistic personality features, and acute anxiety symptoms (PTSD and General Anxiety Disorder [GAD]) among 342 Israeli female adults during the November 2012 eruption of violence in the Middle East. Results demonstrate an association between exposure severity and acute anxiety symptoms (both PTSD and GAD) for individuals with high levels of pathological narcissism but not for those with low levels of pathological narcissism. These results suggest that individuals with narcissistic personality features are at high risk for the development of acute anxiety symptoms following exposure to uncontrollable and life-threatening mass trauma. The findings underscore the role of intra-personal resources in the immediate psychological aftermath of war by highlighting the increased risk associated with narcissistic personality features. Theoretical and clinical implications of the findings are discussed.

Objective To analyze the relationships between alcohol misuse and two types of acute health care use—hospital admissions and emergency room (ER) episodes. Data Sources/Study Setting The first (2001/2002) and second (2004/2005) waves of the National Epidemiological Survey of Alcohol and Related Conditions (NESARC). Study Design Longitudinal study using a group of adults (18–60 years in Wave 1, N=23,079). Gender-stratified regression analysis adjusted for a range of covariates associated with health care use. First-difference methods corrected for potential omitted variable bias. Data Collection The target population of the NESARC was the civilian noninstitutionalized population aged 18 and older residing in the United States and the District of Columbia. The survey response rate was 81 percent in Wave 1 (N=43,093) and 65 percent in Wave 2 (N=34,653). Principal Findings Frequent drinking to intoxication was positively associated with hospital admissions for both men and women and increased the likelihood of using ER services for women. Alcohol dependence and/or abuse was related to higher use of ER services for both genders and increased hospitalizations for men. Conclusions These findings provide updated and nationally representative estimates of the relationships between alcohol misuse and health care use, and they underscore the potential implications of alcohol misuse on health care expenditures.

Climate change and its impact on health continues to receive inadequate attention in the nursing literature, especially in the Arab region. This study explored the knowledge of and attitudes toward climate change and its effect on health among nursing students from four Arab countries. A cross-sectional study was conducted among a convenience sample of 1,059 baccalaureate nursing students from four Arab countries using the New Ecological Paradigm scale and an adapted questionnaire. The findings indicate an average range of attitude toward the environment, with country of residence, type of community, academic-year level, and climate change related variables as significant factors influencing students' attitudes. A moderate level of knowledge about the potential health related impacts of climate change was revealed. Students from Saudi Arabia and Palestinian Territory reported a significantly higher level of knowledge than Egyptian and Iraqi students. Most of the respondents reported that all identified health related effects of climate change have already increased, while more than two-thirds reported that each of the health-related impacts would increase within the next 20 years. The findings underscore the need for more coverage of topics related to climate change and its health-related impacts in nursing education curricula in Arab countries. © 2017 Wiley Periodicals, Inc.

Past research has documented pervasive genetic influences on emotional and behavioral disturbance across the life span and on liability to adult psychiatric disorder. Increasingly, interest is turning to mechanisms of gene-environment interplay in attempting to understand the earliest manifestations of genetic risk. We report findings from a prospective adoption study, which aimed to test the role of evocative gene-environment correlation in early development. Included in the study were 561 infants adopted at birth and studied between 9 and 27 months, along with their adoptive parents and birth mothers. Birth mother psychiatric diagnoses and symptoms scales were used as indicators of genetic influence, and multiple self-report measures were used to index adoptive mother parental negativity. We hypothesized that birth mother psychopathology would be associated with greater adoptive parent negativity and that such evocative effects would be amplified under conditions of high adoptive family adversity. The findings suggested that genetic factors associated with birth mother externalizing psychopathology may evoke negative reactions in adoptive mothers in the first year of life, but only when the adoptive family environment is characterized by marital problems. Maternal negativity mediated the effects of genetic risk on child adjustment at 27 months. The results underscore the importance of genetically influenced evocative processes in early development.

The aim of this study was to build a detailed, integrative profile of the correlates of young adults' feelings of loneliness, in terms of their current health and functioning and their childhood experiences and circumstances. Data were drawn from the Environmental Risk Longitudinal Twin Study, a birth cohort of 2232 individuals born in England and Wales in 1994 and 1995. Loneliness was measured when participants were aged 18. Regression analyses were used to test concurrent associations between loneliness and health and functioning in young adulthood. Longitudinal analyses were conducted to examine childhood factors associated with young adult loneliness. Lonelier young adults were more likely to experience mental health problems, to engage in physical health risk behaviours, and to use more negative strategies to cope with stress. They were less confident in their employment prospects and were more likely to be out of work. Lonelier young adults were, as children, more likely to have had mental health difficulties and to have experienced bullying and social isolation. Loneliness was evenly distributed across genders and socioeconomic backgrounds. Young adults' experience of loneliness co-occurs with a diverse range of problems, with potential implications for health in later life. The findings underscore the importance of early intervention to prevent lonely young adults from being trapped in loneliness as they age.

An information needs study of clinical specialists and biomedical researchers was conducted at the US National Institutes of Health (NIH) to inform library services and contribute to a broader understanding of information use in academic and research settings. A random stratified sample by job category of 500 NIH scientists was surveyed by telephone by an independent consultant using a standardized information industry instrument, augmented with locally developed questions. Results were analyzed for statistical significance using t- tests and chi square. Findings were compared with published studies and an aggregated dataset of information users in business, government, and health care from Outsell. The study results highlighted similarities and differences with other studies and the industry standard, providing insights into user preferences, including new technologies. NIH scientists overwhelmingly used the NIH Library (424/500), began their searches at the library's Website rather than Google (P = or< 0.001), were likely to seek information themselves (474/500), and valued desktop resources and services. While NIH staff work in a unique setting, they share some information characteristics with other researchers. The findings underscored the need to continue assessing specialized needs and seek innovative solutions. The study led to improvements or expansion of services such as developing a Website search engine, organizing gene sequence data, and assisting with manuscript preparation.
Size matters: a meta-analysis on the impact of hospital size on patient mortality.
Fareed, Naleef
2012-06-01
This paper seeks to understand the relationship between hospital size and patient mortality. Patient mortality has been used by several studies in the health services research field as a proxy for measuring healthcare quality. A systematic review is conducted to identify studies that investigate the impact of hospital size on patient mortality. Using the findings of 21 effect sizes from 10 eligible studies, a meta-analysis is performed using a random effects model. Subgroup analyses using three factors--the measure used for hospital size, type of mortality measure used and whether mortality was adjusted or unadjusted--were utilised to investigate their moderating influence on the study's primary relationship. Results from this analysis indicate that big hospitals have lower odds of patient mortality versus small hospitals. Specifically, the probability of patient mortality in a big hospital, in reference to a small hospital, is 11% less. Subgroup analyses show that studies with unadjusted mortality rates have an even lower overall odds ratio of mortality versus studies with adjusted mortality rates. Aside from some limitations in data reporting, the findings of this paper support theoretical notions that big hospitals have lower mortality rates than small hospitals. Guidelines for better data reporting and future research are provided to further explore the phenomenon. Policy implications of this paper's findings are underscored and a sense of urgency is called for in an effort to help improve the state of a healthcare system that struggles with advancing healthcare quality. © 2012 The Author.

With Parkinson's disease (PD) prevalence rates steadily increasing and long-term adherence to regular physical activity and exercise often difficult to achieve, it is imperative to investigate factors promoting adherence to secondary prevention programs (SPP) that help limit the progression of motor and nonmotor signs and symptoms of the disease. Caring interactions between patients and their rehabilitation team may be particularly germane to individuals with PD, given the physical and psychosocial issues that often accompany this disease (eg, loss of physical function, depression, apathy, and cognitive impairments). Considering this reasoning, the purpose of the present study was twofold: (1) to gain a better understanding of the nature of caring in an SPP setting from a patient perspective and (2) to discover what implications, if any, caring has on relevant patient-centered behaviors such as effort and adherence to SPPs. Ten individuals with PD were recruited. In-depth, qualitative interviews were performed using a semistructured interview guide. Inductive content analysis was used to identify themes representing participants' experiences of caring in the SPP setting. Six themes emerged from the data analysis. The first 4 themes described how rehabilitation providers fostered caring in the SPP setting: showing interest, creating a supportive atmosphere, benevolence, and paying attention. Participants described instances when rehabilitation providers (physical therapy assistants, physical therapy students, and exercise specialists) showed interest by asking personal questions and remembering personal information. A supportive environment was facilitated by making participants feel supported, welcomed, and valued. Benevolence was apparent when rehabilitation providers demonstrated kindness and approached their work as "more than just a job." Finally, the importance of feeling that rehabilitation providers "paid attention" to patients by giving them undivided consideration and by aiding with exercises was emphasized. This latter finding is akin to Nodding's concept of "engrossment," a key component of caring, which may be an important issue in the face of increasing use of technological devices (eg, laptop computers and i-pads) that may unintentionally direct rehabilitation providers' attention away from their patients. The final 2 themes-rehabilitation attendance and rehabilitation effort-pertaining to aim 2 of the study, are novel in underscoring the importance of caring with respect to patient behaviors. Several practical implications can be gleaned from the current study including (but not limited to) remembering personal information about the patient, providing patients with undivided attention, providing support for patients, and making patients feel welcome. These findings underscore the importance of addressing affective skills in training future rehabilitation practitioners. Findings also reveal salient implications associated with caring, namely enhanced rehabilitation attendance and effort. Finally, results highlight the need to examine the generalizability of caring elements identified in the current study and to quantitatively assess caring antecedents and outcomes in SPP settings.

Aberrant glycosylation is a well-described hallmark of cancer. In a previous ovarian cancer case control study that examined polymorphisms in 26 glycosylation-associated genes, we found strong statistical evidence (P = 0.00017) that women who inherited two copies of a single-nucleotide polymorphism in the UDP-N-acetylgalactosamine:polypeptide N-acetylgalactosaminyltransferase, GALNT1, had decreased ovarian cancer risk. The current study attempted to replicate this observation. The GALNT1 single-nucleotide polymorphism rs17647532 was genotyped in 6,965 cases and 8,377 controls from 14 studies forming the Ovarian Cancer Association Consortium. The fixed effects estimate per rs17647532 allele was null (odds ratio, 0.99; 95% confidence interval, 0.92–1.07). When a recessive model was fit, the results were unchanged. Test for hetero geneity of the odds ratios revealed consistency across the 14 replication sites but significant differences compared with the original study population (P = 0.03). This study underscores the need for replication of putative findings in genetic association studies. PMID:20142253

Because psychological aspects often are underscored in the generation of tinnitus, we assessed the neuropsychological status in our group of patients. We found an increased number of abnormal electronystagmography (ENG) recordings in tinnitus patients. The aim of this study was to compare the ENG outcome with the patients' neuropsychological status. We carried out the study on 69 subjects complaining of tinnitus and on 43 healthy persons. We performed clinical neurootological examinations and ENG tests on all patients. Neuropsychological evaluation was conducted by means of the Beck Depression Inventory (BDI), the Hospital Anxiety and Depression (HAD) test, the Mini Mental Status (MMS) test, and the Trail-Making Test (TMT). In 46 patients (66.6%), we found abnormal ENG outcomes (central, 42%; peripheral, 13.0%; mixed, 11.6%). Neuropsychological tests revealed abnormal scores: for the BDI, 43.5% of patients; for the HAD-A, 72.5%; for the HAD-D, 47.8%; for the MMS, 27.5%; and for the TMT, 55.1%. We did not find correlation between the ENG outcomes and neuropsychological test scores. We did not find correlation between the overall ENG outcomes and neuropsychological test scores, with one exception; we found the occurrence of abnormal neuropsychological test scores and the ENG outcome indicating central vestibular dysfunction. Our study showed that despite a high frequency of vestibular system dysfunction signs and a high incidence of abnormal neuropsychological test scores in tinnitus patients, only one correlation existed between these two results.

A cross-sectional design was employed retrospectively to evaluate injuries self-reported by 71 pre-professional ballet dancers over one season. Some of the descriptive findings of this survey were consistent with those of previous research and suggest particular demographic and injury trends in pre-professional ballet. These results include gender distribution, mean age and age range of participants, training hours, injury location, acute versus overuse injuries, as well as average number of physiotherapy treatments per dancer. Other results provide information that was heretofore unreported or inconsistent with previous investigations. These findings involved proportion of dancers injured, average number of injuries per dancer, overall injury incidence during an 8.5 month period, incidence rate by technique level, mean time loss per injury, proportion of recurrent injury, and activity practiced at time of injury. The results of univariate analyses revealed several significant findings, including a decrease in incidence rate of injury with increased months of experience in the pre-professional program, dancers having lower injury risk in rehearsal and performance than in class, and a reduced risk of injury for dancers at certain technique levels. However, only this latter finding remained significant in multivariate analysis. The results of this study underscore the importance of determining injury rates by gender, technique level, and activity setting in addition to overall injury rates. They also point to the necessity of looking at both overall and individual dancer-based injury risks.

African Americans experience the highest burden of cancer incidence and mortality in the United States and have been persistently less likely to receive interventional care, even when such care has been proven superior to conservative management by randomized controlled trials. The presence of disparities in access to radiation therapy (RT) for African American cancer patients has rarely been examined in an expansive fashion. An extensive literature search was performed using the PubMed database to examine studies investigating disparities in RT access for African Americans. A total of 55 studies were found, spanning 11 organ systems. Disparities in access to RT for African Americans were most prominently study in cancers of the breast (23 studies), prostate (7 studies), gynecologic system (5 studies), and hematologic system (5 studies). Disparities in RT access for African Americans were prevalent regardless of organ system studied and often occurred independently of socioeconomic status. Fifty of 55 studies (91%) involved analysis of a population-based database such as Surveillance, Epidemiology and End Result (SEER; 26 studies), SEER-Medicare (5 studies), National Cancer Database (3 studies), or a state tumor registry (13 studies). African Americans in the United States have diminished access to RT compared with Caucasian patients, independent of but often in concert with low socioeconomic status. These findings underscore the importance of finding systemic and systematic solutions to address these inequalities to reduce the barriers that patient race provides in receipt of optimal cancer care.

The HPTN 067/Alternative Dosing to Augment Pre-Exposure Prophylaxis Pill Taking (ADAPT) study evaluated daily and non-daily dosing schedules for oral pre-exposure prophylaxis (PrEP) to prevent HIV. A qualitative sub-study including focus groups and in-depth interviews was conducted among men who have sex with men participating in New York City to understand their experience with PrEP and study dosing schedules. The 37 sub-study participants were 68% black, 11% white, and 8% Asian; 27% were of Hispanic/Latino ethnicity. Mean age was 34 years. Themes resulting from qualitative analysis include: PrEP is a significant advance for HIV prevention; non-daily dosing of PrEP is congruent with HIV risk; and pervasive stigma connected to HIV and risk behavior is a barrier to PrEP adherence, especially for non-daily dosing schedules. The findings underscore how PrEP intersects with other HIV prevention practices and highlight the need to understand and address multidimensional stigma related to PrEP use.

Abstract. This review brings together a collection of studies that specifically use wide-field high-resolution mesoscopic level imaging techniques (intrinsic signal optical imaging; voltage-sensitive dye optical imaging) to image the cortical point spread (PS): the total spread of cortical activation comprising a large neuronal ensemble evoked by spatially restricted (point) stimulation of the sensory periphery (e.g., whisker, pure tone, point visual stimulation). The collective imaging findings, combined with supporting anatomical and electrophysiological findings, revealed some key aspects about the PS including its very large (radius of several mm) and relatively symmetrical spatial extent capable of crossing cytoarchitectural borders and trespassing into other cortical areas; its relationship with underlying evoked subthreshold activity and underlying anatomical system of long-range horizontal projections within gray matter, both also crossing borders; its contextual modulation and plasticity; the ability of its relative spatiotemporal profile to remain invariant to major changes in stimulation parameters; its potential role as a building block for integrative cortical activity; and its ubiquitous presence across various cortical areas and across mammalian species. Together, these findings advance our understanding about the neocortex at the mesoscopic level by underscoring that the cortical PS constitutes a fundamental motif of neocortical structure–function relationship.

The high rate of therapeutic failure in the management of alcohol use disorders (AUDs) underscores the urgent need for novel and effective strategies that can deter ethanol consumption. Recent findings from our group showed that ivermectin (IVM), a broad-spectrum anthelmintic with high tolerability and optimal safety profile in humans and animals, antagonized ethanol-mediated inhibition of P2X4 receptors (P2X4Rs) expressed in Xenopus oocytes. This finding prompted us to hypothesize that IVM may reduce alcohol consumption; thus, in the present study we investigated the effects of this agent on several models of alcohol self-administration in male and female C57BL/6 mice. Overall, IVM (1.25–10 mg/kg, intraperitoneal) significantly reduced 24-h alcohol consumption and intermittent limited access (4-h) binge drinking, and operant alcohol self-administration (1-h). The effects on alcohol intake were dose-dependent with the significant reduction in intake at 9 h after administration corresponding to peak IVM concentrations (Cmax) in the brain. IVM also produced a significant reduction in 24-h saccharin consumption, but did not alter operant sucrose self-administration. Taken together, the findings indicate that IVM reduces alcohol intake across several different models of self-administration and suggest that IVM may be useful in the treatment of AUDs. PMID:22465817
Bored in the USA: Experience sampling and boredom in everyday life.

We report new evidence on the emotional, demographic, and situational correlates of boredom from a rich experience sample capturing 1.1 million emotional and time-use reports from 3,867 U.S. adults. Subjects report boredom in 2.8% of the 30-min sampling periods, and 63% of participants report experiencing boredom at least once across the 10-day sampling period. We find that boredom is more likely to co-occur with negative, rather than positive, emotions, and is particularly predictive of loneliness, anger, sadness, and worry. Boredom is more prevalent among men, youths, the unmarried, and those of lower income. We find that differences in how such demographic groups spend their time account for up to one third of the observed differences in overall boredom. The importance of situations in predicting boredom is additionally underscored by the high prevalence of boredom in specific situations involving monotonous or difficult tasks (e.g., working, studying) or contexts where one's autonomy might be constrained (e.g., time with coworkers, afternoons, at school). Overall, our findings are consistent with cognitive accounts that cast boredom as emerging from situations in which engagement is difficult, and are less consistent with accounts that exclusively associate boredom with low arousal or with situations lacking in meaning.

Using vignettes to rethink Latino-white disparities in self-rated health
Bzostek, Sharon; Sastry, Narayan; Goldman, Noreen; Pebley, Anne; Duffy, Denise
2016-01-01
Researchers often rely on respondents’ self-rated health (SRH) to measure social disparities in health, but recent studies suggest that systematically different reporting styles across groups can yield misleading conclusions about disparities in SRH. In this study, we test whether this finding extends to ethnic differences in self-assessments of health in particular domains. We document differences between US-born whites and four Latino subgroups in respondents’ assessments of health in six health domains using data from the second wave of the Los Angeles Family and Neighborhood Study (N=1468). We use both conventional methods and an approach that uses vignettes to adjust for differential reporting styles. Our results suggest that despite consistent evidence from the literature that Latinos tend to rate their overall health more poorly than whites, and that Latino immigrants report worse SRH than US-born Latinos, this pattern is not true of self-reports in individual health domains. We find that at the bivariate level, US-born whites (and often US-born Mexicans) have significantly more pessimistic reporting styles than Latino immigrants. After adding controls, we find evidence of significantly different reporting styles for only one domain: US-born Mexicans and whites consistently interpret head pain more severely than the other Latino subgroups. Finally, we find that both before and after adjusting for differences in rating styles across groups, non-Mexican Latino immigrants report better social and physical functioning and less pain than other groups. Our findings underscore the advantages of domain-specific ratings when evaluating ethnic differences in self-assessments of health. We encourage researchers studying social disparities in health to consider respondents’ self-assessments in a variety of domains, and to also investigate (when possible) potential biases in their findings due to different reporting styles. The anchoring vignettes approach we use is one potential method for overcoming biases due to different rating styles across groups. PMID:26706402

The current study examined whether commonly observed age differences in affective experience among community samples of healthy adults would generalize to a group of adults who live with significant functional disability. Age differences in daily affect and affective reactivity to daily stressors among a sample of participants with spinal cord injury were compared to a non-injured sample. Results revealed that patterns of affective experience varied by sample. Among non-injured adults, older age was associated with lower levels of daily negative affect (NA), higher levels of daily positive affect (PA), and less negative affective reactivity in response to daily stressors. In contrast, among participants with spinal cord injury, no age differences emerged. Findings, which support the model of Strength and Vulnerability Integration (SAVI), underscore the importance of taking life context into account when predicting age differences in affective well-being.

(Where) Is Functional Decline Isolating? Disordered Environments and the Onset of Disability.
Schafer, Markus H
2018-03-01
The onset of disability is believed to undermine social connectedness and raise the risk of social isolation, yet spatial environments are seldom considered in this process. This study examines whether unruly home and neighborhood conditions intensify the association between disability onset and several dimensions of social connectedness. I incorporate longitudinal data from the National Social Life, Health, and Aging Project, which contains environmental evaluations conducted by trained observers ( N = 1,558). Results from Poisson, ordinal logistic, and linear regression models reveal heterogeneous consequences of disablement: disability onset was associated with reduced core network size, fewer friends, lower likelihood of social interaction, and less overall social connectedness-though mainly when accompanied by higher levels of household disorder. There was limited evidence that neighborhood disorder moderated consequences of disability. Findings point to the importance of the home as an environmental resource and underscore important contextual contingencies in the isolating consequences of disability.
Scala vestibuli cochlear implantation in patients with partially ossified cochleas.
Berrettini, Stefano; Forli, Francesca; Neri, Emanuele; Segnini, Giovanni; Franceschini, Stefano Sellari
2002-11-01
Partial cochlear obstruction is a relatively common finding in candidates for cochlear implants and frequently involves the inferior segment of the scala tympani in the basal turn of the cochlea. In such patients, the scala vestibuli is often patent and offers an alternative site for implantation. The current report describes two patients with such partial obstruction of the inferior segment of the basal cochlear turn, caused in one case by systemic vasculitis (Takayasu's disease) and in the other by obliterative otosclerosis. A scala vestibuli implantation allowed for complete insertion of the electrode array. No problems were encountered during the surgical procedures and the good post-operative hearing and communicative outcomes achieved were similar to those reported in patients without cochlear ossification. The importance of accurate pre-operative radiological study of the inner ear is underscored, to disclose the presence and define the features of the cochlear ossification and ultimately to properly plan the surgical approach.
Mental health of adolescents with currently and formerly incarcerated parents
Davis, Laurel; Shlafer, Rebecca J.
2017-01-01
Reliable information about children of incarcerated people is difficult to obtain, and major gaps exist in our understanding of their well-being. This study aims to determine whether adolescents with incarcerated parents report higher levels of mental health problems than those without an incarcerated parent, and whether the relationship between parental incarceration and adolescent mental health is moderated by parent-child relationships. Using a statewide survey from one US state, we compared adolescents with a currently incarcerated parent to those with a formerly incarcerated parent and those with no history of parental incarceration on self-reported indicators of mental health, and examined whether strong parent-child relationships were protective against mental health concerns. Results indicate that adolescents with incarcerated parents are at elevated risk for mental health problems, and strong parent-child relationships partially buffer children from risk. Findings underscore the need for more investment in effective early interventions for adolescents in highly adverse contexts. PMID:28011442

The present study examined the role of mothers' communication with children about interparental disputes in associations between interparental conflict and child psychological maladjustment in a sample of 227 children and their parents followed over a one-year span. Most of the time (i.e., 79.8%) mothers reported that they would communicate with their children following interparental disputes, with the vast majority of those communications containing relatively constructive depictions of interparental conflict. Post-conflict communications were not associated with children's adjustment above and beyond the impact of interparental conflict. However, maternal communications underscoring family cohesion and warmth, emphasizing remorse for engaging in the interparental disagreement, and denying the occurrence of the dispute each moderated associations between interparental conflict and child externalizing symptoms in distinct, complex ways. The findings in general suggest that not all positive communications have the beneficial impact on children that parents may have intended.

Objective The study examines family caregivers’ health changes over 1 year on four health dimensions and explores the association of differential health trajectories with adult day service (ADS) use and caregiving transitions. Method The participants were 153 primary caregivers of individuals with dementia (IWDs) who provided information on care situations and their own health at baseline, 6-month, and 12-month interviews. Results Caregivers showed increasing functional limitations and decreasing bodily pain over time, whereas role limitation and general health perception remained stable. Furthermore, caregivers’ trajectories of functional limitation were associated with their extent of ADS use at baseline and their relatives’ placement. Discussion Health is multidimensional; all dimensions of caregiver health do not change in a uniform manner. The findings underscore the importance of the association of caregiving transitions and caregiver health and the potential health benefits of ADS use for family caregivers. PMID:25348275
Hereditary neuropathy with liability to pressure palsy: two cases of difficult diagnosis.
Beydoun, Said R; Cho, Justin
2013-09-01
Hereditary neuropathy with liability to pressure palsies (HNPP) is an inherited autosomal dominant disorder that causes a polyneuropathy with predisposition for involvement at sites of compression and is often underdiagnosed or misdiagnosed due to its heterogeneity in clinical and electrophysiological presentation. We report 2 cases of HNPP, which were initially diagnosed and treated as either an acquired demyelinating disorder or alternative inherited demyelinating disorder. Thorough evaluation of repeat electrodiagnostic studies and genetic testing confirmed the diagnosis of HNPP in both cases. One case showed the classic peripheral myelin protein 22 (PMP22) deletion and the other case showed a previously reported single base pair deletion at Leu145 causing a frameshift mutation at the PMP22 gene. These cases underscore the difficulty of diagnosing HNPP, because of the variations in clinical and electrophysiological findings and reinforce the importance of a combination high index of clinical suspicion, electrodiagnostic testing, and genetic testing to make the diagnosis.

The purpose of this study is to concurrently examine the impact of individual and organizational characteristics on the decision to adopt the evidence-based practice (EBP) motivational interviewing (MI) among directors and staff (n = 311) in community health organizations (n = 92). Results from hierarchical linear modeling indicated that, at the individual level, attitudes toward EBPs and race each predicted directors' decisions to adopt, while gender predicted staff's decisionmaking. At the organizational level, organizational climate was inversely associated with both staff's and directors' decisions to adopt MI. Organizational barriers to implementing EBPs and use of reading materials and treatment manuals were related to directors' decision to adopt. Type of organization and staff attributes were associated with staff's decision to adopt. These findings underscore the need to tailor dissemination and implementation strategies to address differences between directors and staff in the adoption of EBPs.

Rapid changes in health care have underscored the need for reform in health professions education, including nursing education. One of many problems cited in the nursing and other health sciences education literature is overcrowded curricula; therefore, an evaluation of content is necessary. The purpose of this study was to determine whether differences exist in the frequency that physical examination techniques are performed by associate and baccalaureate degree prepared nurses. Participants completed a survey on performance of various physical examination techniques. A Mann-Whitney test showed no differences between the two groups in terms of frequency of techniques performed. A small negative correlation was found between frequency and years of experience with the nutrition assessment category. A comparison of physical examination content covered in baccalaureate and associate degree nursing programs is needed to further understand these findings.
Efficient receptive field tiling in primate V1
Nauhaus, Ian; Nielsen, Kristina J.; Callaway, Edward M.
2017-01-01
The primary visual cortex (V1) encodes a diverse set of visual features, including orientation, ocular dominance (OD) and spatial frequency (SF), whose joint organization must be precisely structured to optimize coverage within the retinotopic map. Prior experiments have only identified efficient coverage based on orthogonal maps. Here, we used two-photon calcium imaging to reveal an alternative arrangement for OD and SF maps in macaque V1; their gradients run parallel but with unique spatial periods, whereby low SF regions coincide with monocular regions. Next, we mapped receptive fields and find surprisingly precise micro-retinotopy that yields a smaller point-image and requires more efficient inter-map geometry, thus underscoring the significance of map relationships. While smooth retinotopy is constraining, studies suggest that it improves both wiring economy and the V1 population code read downstream. Altogether, these data indicate that connectivity within V1 is finely tuned and precise at the level of individual neurons. PMID:27499086

At night pedestrians tend to overestimate their conspicuity to oncoming drivers, but little is known about factors affecting pedestrians' conspicuity estimates. This study examines how headlamp intensity and pedestrians' clothing influence judgments of their own conspicuity. Forty-eight undergraduate students estimated their own conspicuity on an unilluminated closed road by walking in front of a stationary vehicle to the point at which they judged that they were just recognizable to the driver. Unknown to the participants, high beam intensity was manipulated between subjects by placing neutral density filters on the headlamps. Estimated conspicuity distances did not significantly vary with changes in headlamp intensity even when only 3% of the illumination from the headlamps was present. These findings underscore the need to educate pedestrians about the visual challenges that drivers face at night and the need to minimize pedestrians' exposure to traffic flow at night. © 2013.
Pollution Comes Home and Gets Personal: Women's Experience of Household Chemical Exposure*

2009-01-01
We report on interviews conducted with participants in a novel study about environmental chemicals in body fluids and household air and dust. Interviews reveal how personal and collective environmental history influence the interpretation of exposure data, and how participants fashion an emergent understanding of environmental health problems from the articulation of science and experience. To the illness experience literature, we contribute a framework for analyzing a new category of embodied narratives—“exposure experience”—that examines the mediating role of science. We update social scientific knowledge about social responses to toxic chemicals during a period in which science alters public understanding of chemical pollution. This article is among the first published accounts of participants' responses to learning personal exposure data, research identified as critical to environmental science and public health. Our findings raise the importance of reporting even uncertain science and underscore the value of a community-based reporting strategy. PMID:19181047
Non-metabolic functions of glycolytic enzymes in tumorigenesis.
Yu, X; Li, S
2017-05-11
Cancer cells reprogram their metabolism to meet the requirement for survival and rapid growth. One hallmark of cancer metabolism is elevated aerobic glycolysis and reduced oxidative phosphorylation. Emerging evidence showed that most glycolytic enzymes are deregulated in cancer cells and play important roles in tumorigenesis. Recent studies revealed that all essential glycolytic enzymes can be translocated into nucleus where they participate in tumor progression independent of their canonical metabolic roles. These noncanonical functions include anti-apoptosis, regulation of epigenetic modifications, modulation of transcription factors and co-factors, extracellular cytokine, protein kinase activity and mTORC1 signaling pathway, suggesting that these multifaceted glycolytic enzymes not only function in canonical metabolism but also directly link metabolism to epigenetic and transcription programs implicated in tumorigenesis. These findings underscore our understanding about how tumor cells adapt to nutrient and fuel availability in the environment and most importantly, provide insights into development of cancer therapy.

In the new Affordable Care Act (ACA) health care environment, safety-net institutions continue to serve as important sources of culturally appropriate care for different groups of immigrant patients. This article reports on a qualitative study examining the early ACA enrollment experiences of a range of health care providers (n = 29) in six immigrant-serving safety-net clinics in New Mexico. The six clinics configured their ACA enrollment strategies differently with regard to operations, staffing, and outreach. Providers reported a generally chaotic rollout overall and expressed frustration with strategies that did not accommodate patients, provided little training for providers, and engaged in minimal outreach. Conversely, providers lauded strategies that flexibly met patient needs, leveraged trust through strategic use of staff, and prioritized outreach. Findings underscore the importance of using and funding concerted strategies for future enrollment of immigrant patients, such as featuring community health workers and leveraging trust for outreach.

Cannabis use disorders (CUDs) are prevalent worldwide. Current epidemiological studies underscore differences in behaviors that contribute to cannabis use across cultures that can be leveraged towards prevention and treatment of CUDs. This review proposes a framework for understanding the effects of cross-cultural differences on psychological, neural, and genomic processes underlying CUDs that has the potential to inform global policies and impact global public health. We found that cultural factors may influence (1) the willingness to acknowledge CUD-related symptoms among populations of different countries, and (2) neural responses related to the sense of self, perception, emotion, and attention. These findings leverage the potential effects of culture on neural mechanisms underlying CUDs. As the number of individuals seeking treatment for CUDs increases globally, it is imperative to incorporate cultural considerations to better understand and serve differing populations and develop more targeted treatment strategies and interventions.

Psychosocial adjustment of children affected by HIV/AIDS in Ghana.
Doku, Paul Narh
2010-06-01
The study was conducted to assess the psychosocial adjustment of children affected by HIV/ AIDS in the eastern part of Ghana. Four groups of children (children who lost their parents to AIDS, children who lost their parents through other causes, children living with HIV infected, alive parents and the comparison children who were from the same community but did not have HIV/AIDS-related illness or death in their families) were interviewed on depressive symptoms, prosocial behaviours, hyperactivity, conduct and peer problems using the Strengths and Difficulties Questionnaire (SDQ). Orphans in general and children living with HIV-infected parents consistently demonstrated poorer psychosocial adjustment than comparison children in the same community. The findings underscore the urgency and importance of culturally and developmentally appropriate intervention efforts targeting psychosocial problems among children affected by AIDS and call for more exploration of risk and resilience factors, both individual and contextual, affecting the wellbeing of these children.

We analyze a sample of older U.S. adults with religious backgrounds in order to examine the relationships among two types of divine forgiveness and three indicators of psychological well-being (PWB) as well as the moderating role of attachment to God. Results suggest that (a) feeling forgiven by God and transactional forgiveness from God are not associated with changes in PWB over time, (b) secure attachment to God at baseline is associated with increased optimism and self-esteem, (c) feeling forgiven by God and transactional forgiveness from God are more strongly associated with increased PWB among the securely attached, and (d) among the avoidantly attached, PWB is associated with consistency in one's beliefs, that is, a decreased emphasis on forgiveness from God. Findings underscore the importance of subjective beliefs about God in the lives of many older adults in the United States.
The Impact of Staff Turnover on Workplace Demands and Coworker Relationships
Knight, Danica K.; Becan, Jennifer E.; Flynn, Patrick M.
2016-01-01
Turnover among clinical staff can have detrimental effects on service provision and organizational efficiency. But how does it affect staff who remain employed at the agency? Researchers at the Institute of Behavioral Research at Texas Christian University sought to answer this question by examining the impact of staff turnover on perceptions of workplace demands and support among 353 clinical staff members from 63 outpatient substance abuse treatment programs. Study results documented that counselors in high-turnover programs reported higher demands (job stress, inadequate staffing) and lower support (communication, collaboration) within their organization, even after controlling for other factors such as decreasing budgets, increasing census, and individual measures of workload. Findings underscore the need to intentionally promote workplace communication and collaboration among staff following the departure of a coworker in order to reduce stress and minimize subsequent turnover among remaining clinical staff.

Much is known about the neural circuits of conditioned fear and its relevance to understanding anxiety disorders, but less is known about other anxiety-related behaviors such as active avoidance. Using a tone-signaled, platform-mediated avoidance task, we observed that pharmacological inactivation of the prelimbic prefrontal cortex (PL) delayed avoidance. Surprisingly, optogenetic silencing of PL glutamatergic neurons did not delay avoidance. Consistent with this, inhibitory but not excitatory responses of rostral PL neurons were associated with avoidance training. To test the importance of these inhibitory responses, we optogenetically stimulated PL neurons to counteract the tone-elicited reduction in firing rate. Photoactivation of rostral (but not caudal) PL neurons at 4 Hz impaired avoidance. These findings suggest that inhibitory responses of rostral PL neurons signal the avoidability of a potential threat and underscore the importance of designing behavioral optogenetic studies based on neuronal firing responses.

While there has recently been considerable research and public investment in strategies to address homelessness in Canada, food charity remains the primary response to hunger, with little evaluation of current efforts and no initiatives to develop more effective approaches. Using data from a 2010-2011 survey of charitable food assistance in five Canadian cities, this study was undertaken to describe charitable meal provisioning in each city and to compare the relative roles of emergency programs and multi-service agencies and their capacity to meet food needs. Most meals were provided by multi-service agencies, but like emergency programs, these agencies were heavily dependent on donations and they were more likely than emergency programs to report constraints and service interruptions because demands exceeded available supplies. Our findings underscore the resource-limited and often fragile nature of charitable meal programs in Canada and highlight the need for more effective models of response to problems of hunger.
The stress-buffering effects of hope on changes in adjustment to caregiving in multiple sclerosis.
Madan, Sindia; Pakenham, Kenneth I
2015-09-01
This study examined the direct and stress-buffering effects of global hope and its components (agency and pathways) on changes in adjustment to multiple sclerosis caregiving over 12 months. A total of 140 carers and their care-recipients completed questionnaires at Time 1 and 12 months later, Time 2. Focal predictors were stress, hope, agency and pathways, and the adjustment outcomes were anxiety, depression, positive affect, positive states of mind and life satisfaction. Results showed that as predicted, greater hope was associated with better adjustment after controlling for the effects of initial adjustment and caregiving and care-recipient illness variables. No stress-buffering effects of hope emerged. Regarding hope components, only the agency dimension emerged as a significant predictor of adjustment. Findings highlight hope as an important protective resource for coping with multiple sclerosis caregiving and underscore the role of agency thinking in this process. © The Author(s) 2013.

This study examined gender differences in family, peer, partner, and mental health characteristics related to sexual experience among emotionally and behaviorally disordered students in therapeutic day schools, a population at elevated risk for negative sexual health outcomes. A total of 417 13- to 20-year-old adolescents reported on their family functioning, peer and partner relationship characteristics, mental health problems, and self-reported sexual behavior. For boys and girls, peer influence and conduct problems predicted sexual experience, and family dysfunction was related to negative peer influence. Greater rejection sensitivity was related to less sexual experience for boys and girls. The final path model revealed indirect effects of family dysfunction on boys' but not girls' sexual experiences. Findings underscore the utility of an ecological approach to understand social and personal mechanisms that increase risk and mitigate negative outcomes among emotionally and behaviorally disordered boys and girls in therapeutic day schools.

This participatory study used PhotoVoice and qualitative description to (a) mentor baccalaureate nursing and college students in workforce diversity research; (b) explore barriers and facilitators encountered by rural American Indian, Hispanic, and other high school students when attending college and pursuing careers in nursing or the health sciences; and (c) model a process of social action to help existing and future students. Baccalaureate nursing and graduate students participated in all stages of research, including dissemination. Five themes emerged from analysis of PhotoVoice data: (a) being afraid; (b) believing; (c) taking small steps; (d) facing fears; and (e) using support systems. Findings underscore the importance of helping students participate in efforts to increase work-force diversity through research. Increasing nursing and health sciences workforce diversity may require strategies developed within and tailored to specific cultures and communities. Copyright 2014, SLACK Incorporated.
Impulsivity moderates the relationship between previous quit failure and cue-induced craving.
Erblich, Joel; Michalowski, Alexandra
2015-12-01
Poor inhibitory control has been shown to be an important predictor of relapse to a number of drugs, including nicotine. Indeed, smokers who exhibit higher levels of impulsivity are thought to have impaired regulation of urges to smoke, and previous research has suggested that impulsivity may moderate cue-induced cigarette cravings. To that end, we conducted a study to evaluate the interplay between failed smoking cessation, cue-induced craving, and impulsivity. Current smokers (n=151) rated their cigarette cravings before and after laboratory to exposure to smoking cues, and completed questionnaires assessing impulsivity and previous failed quit attempts. Findings indicated that shorter duration of previous failed quit attempts was related to higher cue-induced cigarette craving, especially among smokers with higher levels of impulsivity. Results underscore the importance of considering trait impulsivity as a factor in better understanding the management of cue-induced cravings. Copyright © 2015 Elsevier Ltd. All rights reserved.

2016-01-01
The purpose of this study was to explore the relationship between perception of own appearance, Internet pornography consumption, preferences for pornographic actors' appearance, and sexual self-esteem in gay and bisexual men in Norway. An online survey of 477 gay and bisexual men showed that, despite the prevailing muscular and lean gay body ideal, many men with less ideal bodies also preferred to watch pornographic actors with body types similar to their own. Self-perceived attractiveness, having an ideal body type, and viewing Internet pornography in longer sessions each made a unique contribution to higher self-esteem as a sexual partner. Preferring to watch pornographic actors with ideal bodies was not related to sexual self-esteem. The findings underscore the importance for gay or bisexual men of both self-perceived attractiveness and being athletic or young and fit, for a positive self-evaluation of sexual performance and competence.

Objective This study describes the parenting and psychopathology of mothers with ADHD of adolescents with ADHD (MCA), non-ADHD mothers of adolescents with ADHD (CA), and non-ADHD mothers of adolescents without ADHD (COMP). Method Two sets of pairwise comparisons: 1) COMP vs. CA and 2) CA vs. MCA were conducted. We hypothesized that CA would experience greater distress in parenting and psychopathology compared to COMP, and that MCA would experience even more impairment compared to CA. Results Few differences emerged in comparisons of CA and COMP, with the exception of CA reporting greater parent-adolescent conflict and internalizing problems. In contrast, differences consistently emerged in comparisons of MCA and CA showing more difficulty for MCA in parenting and psychopathology. Conclusion These findings underscore the need for treatments that address parental ADHD when adolescent ADHD is the intended target. PMID:23160485

This study examined whether aspects of parenting style (specifically, warmth, autonomy support, and coercion) moderated the association between parental involvement and adherence in youth with type 1 diabetes. Children ages 8 to 16 years with type 1 diabetes and a parent completed assessments of parental involvement, parenting style, and adherence. Parent autonomy support and coercion were associated with adherence but warmth was not. Child report of more parental involvement was associated with better adherence. Warmth, autonomy support, and coercion were not moderators. The findings underscore the importance of parental involvement, operationalized as responsibility for diabetes tasks, and parenting style, specifically coercion and autonomy support, for adherence in pediatric chronic illness management. Longitudinal research is needed to better understand how and why dimensions of involvement (e.g., responsibility, monitoring, support) vary over time and whether they impact outcomes differentially.

From a dynamic systems perspective, transition points in development are times of increased instability, during which behavioral patterns are susceptible to temporary decoupling. This study investigated the impact of the vocabulary spurt on existing patterns of communicative coordination. Eighteen typically developing infants were videotaped at home 1 month before, at, and after the vocabulary spurt. Infants were identified as spurters if they underwent a discrete phase transition in vocabulary development (marked by an inflection point), and compared with a group of nonspurters whose word-learning rates followed a trajectory of continuous change. Relative to surrounding sessions, there were significant reductions in overall coordination of communicative behaviors and in words produced in coordination at the vocabulary spurt session for infants who experienced more dramatic vocabulary growth. In contrast, nonspurters demonstrated little change across sessions. Findings underscore the importance of transitions as opportunities for observing processes of developmental change. PMID:21219063

Recent effective use of TAL Effectors (TALEs) has provided an important approach to the design and synthesis of sequence-specific DNA-binding proteins. However, it is still a challenging task to design and manufacture effective TALE modulators because of the limited knowledge of TALE–DNA interactions. Here we synthesized more than 200 TALE modulators and identified two determining factors of transcription activity in vivo: chromatin accessibility and the distance from the transcription start site. The implementation of these modulators in a gain-of-function screen was successfully demonstrated for four cell lines in migration/invasion assays and thus has broad relevance in this field. Furthermore, a novel TALE–TALE modulator was developed to transcriptionally inhibit target genes. Together, these findings underscore the huge potential of these TALE modulators in the study of gene function, reprogramming of cellular behaviors, and even clinical investigation. PMID:24939900
Cash management and revitalization of public medical centres in Nigeria: a strategic analysis.
Agundu, Prince U C; Okon, Godwin B; Robinson, Eric T
2007-01-01
In times like this, when Nigeria (like many other developing countries) is bracing up to the contemporary challenges posed by adoption and advancement of globally driven millennium development goals (MDGs), public medical centers (PMCs) cannot afford to be reckoned with financial epilepsy, bankruptcy, and degeneracy. This concern informed the thrust of the study. In the process, pertinent research questions were posed which elicited corresponding hypothetical propositions. With primary data volunteered by 150 administrative officials drawn from PMCs across the country, analytical proceedings were facilitated by the application of chi-square (x2) technique. The findings brought to the fore, the general bad shape of cash management in PMCs in the country. The recommendations for urgent attention underscored the constitution of strategic budget communities (SBCs), revitalization of internal audit committees (IACs), and attraction of goodwill private-sector endowments through convincing justification of the utilization and optimization of current government logistic subventions.

This study compares psychosocial well-being between paternal and maternal orphans in rural China in a sample (N = 459) of children who had lost one parent to HIV and who were in family-based care. Measures included academic marks, education expectation, trusting relationships with current caregivers, self-reported health status, depression, loneliness, posttraumatic stress, and social support. No significant differences were found between maternal and paternal orphans, except that paternal orphans reported better trusting relationships with caregivers than maternal orphans. Children with a healthy surviving parent reported significantly better depression, loneliness, posttraumatic stress, and social support scores than children with a sick parent. Analyses revealed significance with regard to orphan status on academic marks and trusting relationships with caregivers while controlling for age, gender, surviving parent’s health status, and family SES. Findings underscore the importance of psychosocial support for children whose surviving parent is living with HIV or another illness. PMID:20133172

We determined factors associated with occupational transmission in Wisconsin during the 2003 outbreak of prairie dog–associated monkeypox virus infections. Our investigation included active contact surveillance, exposure-related interviews, and a veterinary facility cohort study. We identified 19 confirmed, 5 probable, and 3 suspected cases. Rash, headache, sweats, and fever were reported by >80% of patients. Occupationally transmitted infections occurred in 12 veterinary staff, 2 pet store employees, and 2 animal distributors. The following were associated with illness: working directly with animal care (p = 0.002), being involved in prairie dog examination, caring for an animal within 6 feet of an ill prairie dog (p = 0.03), feeding an ill prairie dog (p = 0.002), and using an antihistamine (p = 0.04). Having never handled an ill prairie dog (p = 0.004) was protective. Veterinary staff used personal protective equipment sporadically. Our findings underscore the importance of standard veterinary infection-control guidelines. PMID:17953084
Truth is at hand: How gesture adds information during investigative interviews
Broaders, Sara C.; Goldin-Meadow, Susan
2010-01-01
The accuracy of information obtained in forensic interviews is critically important to credibility in our legal system. Research has shown that the way interviewers frame questions influences the accuracy of witnesses’ reports. A separate body of research has shown that speakers spontaneously gesture when they talk, and that these gestures can express information not found anywhere in the speaker’s talk. This study of children interviewed about an event that they witnessed joins these two literatures and demonstrates that (1) interviewers’ gestures serve as a source of information and, at times, misinformation that can lead witnesses to report incorrect details; (2) the gestures witnesses spontaneously produce during interviews convey substantive information that is often not conveyed anywhere in their speech, and thus would not appear in written transcripts of the proceedings. These findings underscore the need to attend to and document gestures produced in investigative interviews, particularly interviews conducted with children. PMID:20483837
Infrared light excites cells by changing their electrical capacitance

2012-01-01
Optical stimulation has enabled important advances in the study of brain function and other biological processes, and holds promise for medical applications ranging from hearing restoration to cardiac pace making. In particular, pulsed laser stimulation using infrared wavelengths >1.5 μm has therapeutic potential based on its ability to directly stimulate nerves and muscles without any genetic or chemical pre-treatment. However, the mechanism of infrared stimulation has been a mystery, hindering its path to the clinic. Here we show that infrared light excites cells through a novel, highly general electrostatic mechanism. Infrared pulses are absorbed by water, producing a rapid local increase in temperature. This heating reversibly alters the electrical capacitance of the plasma membrane, depolarizing the target cell. This mechanism is fully reversible and requires only the most basic properties of cell membranes. Our findings underscore the generality of pulsed infrared stimulation and its medical potential.

People with mental disorders are strongly stigmatized. Among mental-health professionals, stigmatizing attitudes often manifest as desire for social distance from people with mental disorders. Currently ascendant biomedical conceptualizations of psychopathology could exacerbate this problem by engendering dehumanization, which is linked to prejudice. Given the clinical implications of such an occurrence, the present research tested a possible mitigation strategy. In an online study of 216 U.S. mental-health clinicians, two strategies for mitigating dehumanization in healthcare were tested—personification, highlighting personal traits of people with mental disorders rather than presenting them as malfunctioning brains, and agency reorientation, underscoring people’s ability to make choices and decisions. This approach yielded significantly less desire for social distance, among clinicians, from a person with depression whose symptoms were explained biologically. These findings may suggest an avenue for decreasing stigma in clinical practice. PMID:27766309
Synthesis and Biological Response of Size-Specific, Monodisperse Drug-Silica Nanoconjugates
Tang, Li; Fan, Timothy M.; Borst, Luke B.; Cheng, Jianjun
2012-01-01
Drug-containing nanoparticles (NPs) with monodisperse, controlled particle sizes are highly desirable for drug delivery. Accumulating evidence suggests that NPs with sizes less than 50 nm demonstrate superior performance in vitro and in vivo. However, it is difficult to fabricate monodisperse, drug-containing NPs with discrete and incremental difference in sizes required for studying and characterizing existing relationships among particle size, biologic processing, and therapeutic functionality. Here, we report a scalable process of fabricating drug-silica conjugated nanoparticles, termed drug-silica nanoconjugates (drug-NCs), which possess monodisperse size distributions and desirable particle sizes as small as 20 nm. We found that 20-nm NCs are superior to their 50-nm and 200-nm NC analogues by 2–5 and 10–20 folds, respectively, with regard to tumor accumulation and penetration, and cellular internalization. These fundamental findings underscore the importance and necessity of further miniaturizing nanomedicine size for optimized drug delivery applications. PMID:22494403
Human rights violations against sex workers: burden and effect on HIV.

We reviewed evidence from more than 800 studies and reports on the burden and HIV implications of human rights violations against sex workers. Published research documents widespread abuses of human rights perpetrated by both state and non-state actors. Such violations directly and indirectly increase HIV susceptibility, and undermine effective HIV-prevention and intervention efforts. Violations include homicide; physical and sexual violence, from law enforcement, clients, and intimate partners; unlawful arrest and detention; discrimination in accessing health services; and forced HIV testing. Abuses occur across all policy regimes, although most profoundly where sex work is criminalised through punitive law. Protection of sex workers is essential to respect, protect, and meet their human rights, and to improve their health and wellbeing. Research findings affirm the value of rights-based HIV responses for sex workers, and underscore the obligation of states to uphold the rights of this marginalised population.

Candida auris and C. haemulonii are closely related, multidrug-resistant emerging fungal pathogens that are not readily distinguishable with phenotypic assays. We studied C. auris and C. haemulonii clinical isolates from 2 hospitals in central Israel. C. auris was isolated in 5 patients with nosocomial bloodstream infection, and C. haemulonii was found as a colonizer of leg wounds at a peripheral vascular disease clinic. Liberal use of topical miconazole and close contact among patients were implicated in C. haemulonii transmission. C. auris exhibited higher thermotolerance, virulence in a mouse infection model, and ATP-dependent drug efflux activity than C. haemulonii. Comparison of ribosomal DNA sequences found that C. auris strains from Israel were phylogenetically distinct from isolates from East Asia, South Africa and Kuwait, whereas C. haemulonii strains from different countries were closely interrelated. Our findings highlight the pathogenicity of C. auris and underscore the need to limit its spread.
Recent patterns of crop yield growth and stagnation.
Ray, Deepak K; Ramankutty, Navin; Mueller, Nathaniel D; West, Paul C; Foley, Jonathan A
2012-01-01
In the coming decades, continued population growth, rising meat and dairy consumption and expanding biofuel use will dramatically increase the pressure on global agriculture. Even as we face these future burdens, there have been scattered reports of yield stagnation in the world's major cereal crops, including maize, rice and wheat. Here we study data from ∼2.5 million census observations across the globe extending over the period 1961-2008. We examined the trends in crop yields for four key global crops: maize, rice, wheat and soybeans. Although yields continue to increase in many areas, we find that across 24-39% of maize-, rice-, wheat- and soybean-growing areas, yields either never improve, stagnate or collapse. This result underscores the challenge of meeting increasing global agricultural demands. New investments in underperforming regions, as well as strategies to continue increasing yields in the high-performing areas, are required.
Maintaining normality and support are central issues when receiving chemotherapy for ovarian cancer.
Ekman, Inger; Bergbom, Ingegerd; Ekman, Tor; Berthold, Harrieth; Mahsneh, Sawsan Majali
2004-01-01
The aim of this study was to enrich the understanding of patients' perspective of being diagnosed and treated for ovarian cancer. A qualitative approach was used to obtain knowledge and insight into patients' experiences and thoughts. Ten Swedish women, diagnosed with ovarian cancer, participated in a total of 23 interviews on 3 occasions: at the time of diagnosis, during chemotherapy, and after completion of chemotherapy. The results of the interpretation of the interviews were formulated in the form of 3 themes: (1) feeling the same despite radical castrating surgery, (2) accepting chemotherapy, and (3) maintaining normality and support. Suggestions of caring implications from our interpretation of the interview data underscore the need to support these women in learning to cope with their feelings of weakness and anxiety. The findings further indicate the potential in narrative methods to identify important issues in comprehensive cancer care.
It’s not only for the money: an analysis of adolescent versus adult entry into street prostitution.
Cobbina, Jennifer E; Oselin, Sharon S
2011-01-01
Numerous studies examine the causal factors of entrance into prostitution and find economic marginalization, substance addiction, and interpersonal networks are common reasons women enter the trade. However, we know less about the role that age of onset plays in shaping female pathways into prostitution. Here, we build from insights into previous research by analyzing not only entry pathways but also how age categories are linked to time spent in the trade and whether the length of time in prostitution exacts a greater “toll” on women. Drawing from the feminist and age of onset literatures, we analyze 40 in-depth interviews with female street prostitutes from five U.S. cities. Our results underscore the importance of age as an organizing feature of women’s pathways into prostitution and the potential associated consequences of working in this trade.
Internal Migration and Sexual Initiation among Never Married Youths in Nigeria
Mberu, Blessing Uchenna; White, Michael J
2013-01-01
The high rates of youth migration to urban and economic centers, in the context of persistent poverty and devastating HIV/AIDS burden, raises intricate social policy challenges in developing countries. This study examines patterns of internal migration and sexual initiation among Nigerian youths, using the 2003 Nigeria DHS data, descriptive statistics, Kaplan-Meier survival curves and discrete-time hazard regression models. Migrants generally show stronger association than non-migrants, and urban-urban migrants show the strongest independent association to early sexual initiation. These outcomes underscore that loss of social capital and exposure to sexually lenient urban environment increase youth's propensity to sexual engagement. Other significant covariates are age, gender, ethnic origin, education, independent living arrangement and formal employment. The findings highlight the inadequacy of policy perspectives that neglect complex contextual nuances across groups and the need to address limited livelihood opportunities that fuel youth migration to urban destinations.

This study examined gender differences in medical advice related to diet and physical activity for obese African American adults (N = 470) with and without diabetes. Data from the 2007-2008 National Health and Nutrition Examination Survey were analyzed using logistic regression analyses. Even after sociodemographic adjustments, men were less likely to report receiving medical advice as compared with women. Both men and women given dietary and physical activity advice were more likely to follow it. Men were less likely to report currently reducing fat or calories, yet men with diabetes were 5 times more likely to state that they were reducing fat and calories as compared with women with diabetes. Gender- and disease state-specific interventions are needed comparing standard care with enhanced patient education. Moreover, these findings necessitate studies that characterize the role of the health care professional in the diagnosis and treatment of obesity and underscore patient-provider relationships.

This study examined how Mexican American youths’ extent of sibling caretaking is related to their personal and school adjustment, and whether mothers’ gender-role attitudes and youths’ familistic beliefs moderate these associations. One hundred and ninety-five Mexican American youth (M age 14.8 years; 64% girls) and their mothers participated in the study. Youth completed questionnaires about their extent of sibling caretaking, their educational aspirations, school involvement, school absences, grades, and their prosocial tendencies. Results indicated that, when examined singly, frequent sibling caretaking was related to youths’ higher educational aspirations, greater prosocial tendencies, and more school engagement for older youth, but also to more school absences. When extensive sibling care was coupled with mothers’ sex-stereotyped attitudes, youth experienced poorer outcomes. Youth who held strong familistic beliefs and were highly involved in sibling care reported lower educational aspirations, particularly girls. Findings underscore the importance of considering socialization influences when evaluating associations between sibling caretaking and youths’ development. PMID:24353372
A qualitative descriptive study of risk reduction for coronary disease among the Hong Kong Chinese.
Chan, Choi Wan; Lopez, Violeta
2014-01-01
Achieving optimal control and reduction in coronary heart disease (CHD) risks in Hong Kong (HK) remains significant and requires exploring. This article addresses the ability to reduce CHD risks among the HK Chinese. Through secondary analysis, a qualitative descriptive design using focus group interviews and content analysis were adopted. Older and younger adults were invited for the study. An interview schedule was used to guide discussions during focus group interviews. Four categories emerged from the data: planning of health actions, control of risk-reducing behavior, perceived opportunities for understanding CHD, and chest pain appraisal. Local culture and population needs play a central role in disease perception and prevention. The findings are essential to target strategies for initiating health acts for younger adults and establish public education resources that underscore understanding of CHD risk, symptom recognition, and disease management, particularly among those middle-aged and older people at high risk and with the diseased populations. © 2013 Wiley Periodicals, Inc.
What it feels like to be me: Linking emotional intelligence, identity, and intimacy.
Maher, Hemali; Winston, Christine N; S, Usha Rani
2017-04-01
The search for the self and for an intimate other are the normative tasks of adolescence and early adulthood. The role of emotions in the resolution of these developmental tasks, however, remains largely under-studied, especially in non-western cultures. The objective of the present study, therefore, was to examine the relationships between emotional intelligence, identity, and intimacy, among Indian adolescents. Differences across genders (boys vs. girls) and types of school (gender segregated vs. integrated) were also explored. A sample of 486 adolescents completed measures of emotional intelligence, identity, and intimacy. Girls scored higher than boys on intimacy, and those from segregated schools scored higher, than those from integrated schools, on emotional intelligence. Significant relationships emerged between emotional intelligence, and identity and intimacy, and were invariant across the groups. These findings underscore the pivotal role that emotional intelligence plays in healthy adolescent development, irrespective of personal and environmental variables.

Empowering leaders optimize working conditions for engagement: a multilevel study.
Tuckey, Michelle R; Bakker, Arnold B; Dollard, Maureen F
2012-01-01
Using a multilevel framework, this study examined the role of empowering leadership at the group level by fire brigade captains in facilitating the individual level motivational processes that underpin work engagement in volunteer firefighters. Anonymous mail surveys were completed by 540 volunteer firefighters from 68 fire brigades and, separately, by 68 brigade captains. As predicted on the basis of the Job Demands-Resources model, increased levels of cognitive demands and cognitive resources partially mediated the relationship between empowering leadership and work engagement. In a three-way Leadership × Demands × Resources interaction, empowering leadership also had the effect of optimizing working conditions for engagement by strengthening the positive effect of a work context in which both cognitive demands and cognitive resources were high. Our findings shed light on a process through which leaders can empower workers and enhance well-being: via their influence on and interaction with the work environment. They also underscore the need to examine work engagement from a multilevel theoretical perspective.
Interpersonal influences on late adolescent girls' and boys' disordered eating.
Shomaker, Lauren B; Furman, Wyndol
2009-04-01
Perceived socio-cultural pressure to be thin has an important impact on disordered eating during early and middle adolescence, but less is known about late adolescence. Most prospective studies included only girls, and less is known about the influence on boys. This study investigated interpersonal influences on changes in late adolescent boys' and girls' symptoms of disordered eating over one year. Participants were a community sample of late adolescents 16-19 years of age (N=199; 49.75% girls), their mothers, and friends. Structural equation modeling revealed that interpersonal pressure to be thin and criticism about appearance predicted increases in disordered eating over time. Late adolescents', mothers' and friends' reports of pressure were associated with disordered eating at Time 1 and Time 2. Further, adolescents' perceptions and friends' reports of pressure to be thin predicted changes in disordered eating over time. Findings underscore the significance of interpersonal relationships for disordered eating during late adolescence in both girls and boys.

We used a population-based sample of 403 Parkinson's disease cases and 405 controls to examine risks by occupation. Results were compared to a previous clinic-based analysis. With censoring of jobs held within 10 years of diagnosis, the following had significantly or strongly increased risks: social science, law and library jobs (OR = 1.8); farming and horticulture jobs (OR = 2.0); gas station jobs (OR = 2.6); and welders (OR = 3.0). The following had significantly decreased risks: management and administration jobs (OR = 0.70); and other health care jobs (OR = 0.44). These results were consistent with other findings for social science and farming occupations. Risks for teaching, medicine and health occupations were not elevated, unlike our previous clinic-based study. This underscores the value of population-based over clinic-based samples. Occupational studies may be particularly susceptible to referral bias because social networks may spread preferentially via jobs. © 2013 Wiley Periodicals, Inc.
'Growing Old' in Shelters and 'On the Street': Experiences of Older Homeless People.
Grenier, Amanda; Sussman, Tamara; Barken, Rachel; Bourgeois-Guérin, Valerie; Rothwell, David
2016-01-01
Homelessness among older people in Canada is both a growing concern, and an emerging field of study. This article reports thematic results of qualitative interviews with 40 people aged 46 to 75, carried out as part of a mixed-methods study of older people who are homeless in Montreal, Quebec, Canada. Our participants included people with histories of homelessness (n = 14) and persons new to homelessness in later life (n = 26). Interviews focused on experiences at the intersections of aging and homelessness including social relationships, the challenges of living on the streets and in shelters in later life, and the future. This article outlines the 5 main themes that capture the experience of homelessness for our participants: age exacerbates worries; exclusion and isolation; managing significant challenges; shifting needs and realities; and resilience, strength, and hope. Together, these findings underscore the need for specific programs geared to the unique needs of older people who are homeless.

The link between behavior problems and low academic achievement is well established, but few studies have examined longitudinal relations between early externalizing behaviors before school entry and low academic achievement following transition to formal schooling. Early inattention has been particularly overlooked, despite strong associations between inattention and reading difficulties later in development. Trajectories of infant and toddler aggression, overactivity, and inattention, developed from parent reports about 1- to 3-year-old children, were examined as predictors of direct assessments of 2nd-grade reading in an at-risk epidemiological study subsample (N = 359). Reports of inattentive and overactive behaviors at ages 1-3 years and changes in inattention through toddlerhood predicted reading achievement in 2nd grade. A parallel process model suggested that the effects of early inattention on reading appear to be most robust. Findings underscore the contribution of social-emotional development to school readiness and the importance of early identification of children with externalizing problems, as early interventions designed to reduce externalizing problems may improve later reading skills.

Among people living with HIV/AIDS (PLHA), the occurrence of post-traumatic stress disorder (PTSD) symptoms associated with HIV diagnosis is a common problem. This study examined HIV diagnosis-related PTSD symptoms and its associated factors among PLHA in rural China. We used baseline data from a randomized controlled trial conducted in Anhui Province, China. Surveys of 522 PLHA were conducted via computer-assisted personal interview method. PTSD symptoms were measured based on re-experiencing, avoidance and arousal of the day of HIV diagnosis. Association between PTSD symptoms and demographic characteristics, physical and social functioning were assessed by multiple regression analysis and structural equation modeling. Social functioning exhibited a direct association with HIV diagnosis-related PTSD symptoms, and also mediated the association between PTSD symptoms and age, family income, and physical functioning. The study findings underscore the importance of developing interventions that alleviate PTSD symptoms and improve social functioning among PLHA in rural China.

Previous modelling studies suggest that thermoelectric power generation is vulnerable to climate change, whereas studies based on historical data suggest the impact will be less severe. Here we explore the vulnerability of thermoelectric power generation in the United States to climate change by coupling an Earth system model with a thermoelectric power generation model, including state-level representation of environmental regulations on thermal effluents. We find that the impact of climate change is lower than in previous modelling estimates due to an inclusion of a spatially disaggregated representation of environmental regulations and provisional variances that temporarily relieve power plants from permit requirements. More specifically, our results indicate that climate change alone may reduce average generating capacity by 2-3% by the 2060s, while reductions of up to 12% are expected if environmental requirements are enforced without waivers for thermal variation. Our work highlights the significance of accounting for legal constructs and underscores the effects of provisional variances in addition to environmental requirements.

A prospective registry was made of all patients hospitalized with atrial fibrillation (AF) in the State of Qatar from 1991 to 2010. Clinical characteristics, management, and outcomes were compared according to ethnicity (Middle Eastern Arab vs South Asian). During this 20-year period, 2857 Arabs and 548 Asians were hospitalized for AF. Arabs were 9 years older and more likely to have hypertension, diabetes mellitus (DM), chronic renal impairment, and dyslipidemia than the Asians. Valvular heart disease and acute coronary syndromes were more common among Asians, while congestive heart failure was more common in Arabs. The overall inhospital mortality was lower in Asians than that of Arabs, while stroke rates were comparable. There was an increase in the prevalence of DM and hypertension in both the groups in the latter years of the study period, but there was no change in mortality trends. Our findings underscore the need to study AF according to ethnicity.
Demographics of the Canadian dairy industry from 1991 to 2011.
Jelinski, Murray D; LeBlanc, Stephen; Kennedy, Richard
2015-07-01
A retrospective study of the demographics of the Canadian dairy industry was conducted using data derived from Statistics Canada's Census of Agriculture from 1991 to 2011. This longitudinal study shows that Canada's dairy industry has undergone considerable consolidation. From 1991 to 2011, the number of dairy producers and dairy farms decreased by 48.9% and 61.9%, respectively. Furthermore, this trend in consolidation is likely to continue; nearly half (45.8%) of all dairy producers in Canada were ≥ 50 y of age in 2011. Not only will most of these producers be retired by 2021, but younger producers will also exit the industry for other reasons. These findings mirror what is occurring in Canada's cow-calf industry, underscoring that supply-managed sectors experience demographic consolidation similar to non-supply managed sectors. These substantial changes will have ramifications for the veterinary profession. There will be fewer but larger farms, and the services and knowledge demanded of veterinarians will change accordingly, which has implications for food animal veterinary education.

There will be fewer but larger farms, and the services and knowledge demanded of veterinarians will change accordingly, which has implications for food animal veterinary education. PMID:26130831

This study examined predictors of readmission for a sample of 522 adolescents enrolled in Medicaid and admitted to three inpatient psychiatric hospitals in Maryland. Comprehensive data on clinical, treatment, and health care system characteristics were collected from archival sources (medical records, Medicaid claims, and Area Resource File). Predictors of readmission were examined with bivariate (Kaplan Meier) and multivariate (Cox Regression) survival techniques. One year readmission rates were 38% with the majority occurring within 3 months after discharge. Adolescent demographic (age and gender), clinical (severity of symptoms, comorbidity, suicidality) and family characteristics (level of family risk) were associated with readmission. However, treatment factors including type of aftercare, post-discharge living environment, medication noncompliance, and hospital provider were among the strongest predictors of readmission. Study findings underscore the importance of careful discharge planning and linkage to appropriate aftercare. The differing rates of readmission across hospitals also suggest that organizational level factors may play a vital role in determining treatment outcomes. PMID:18954182

This longitudinal study examined how a multimethod (youth report, parent report, direct observation) assessment of family relationship quality (cohesion and conflict) in adolescence (age 16 –17) predicted growth and maintenance of effortful control across ages 17, 22, and 23 years old, and, ultimately, subjective well-being, emotional distress, and aggressive behavior in emerging adulthood (23). A diverse sample of 792 youth at age 17 and their families, and youth at ages 22 and 23, were studied to examine family cohesion and conflict and the growth and maintenance of effortful control as predictors of emerging adult social and emotional health. Results indicated that family cohesion and conflict during late adolescence and mean-level effortful control at age 22 each served as unique pathways to emerging adult adjustment. These findings underscore the importance of family functioning during adolescence and the maintenance of effortful control into emerging adulthood for understanding adjustment during the emerging adulthood period.

Misuse of codeine-containing medicines is an emerging global public health concern. The majority of research has been conducted in developed countries (European Members States, Australia, the United States). This study aimed to gain an understanding of unique individual and collective experiences of trajectories of codeine misuse and dependence in South Africa. In-depth interviews were conducted with a purposive sample of adult codeine misusers and dependents ( n = 25). Narratives were analyzed using the empirical phenomenological psychological five-step method. Nine themes with 63 categories emerged, with two additional high levels of abstraction. Findings are illustrated: participant profile and product preferences, motives for use, transitioning to misuse and dependence, pharmacy purchasing and alternative sourcing routes, effects and withdrawal experiences, help-seeking and treatment experiences, and strategies for prevention. The study underscores the need for continued support for enhanced patient awareness of risk of habit forming use and related health consequences and professional pharmacovigilance.

Objective The current study investigates the relationship between romantic attachment style and depressive symptoms between both members of pregnant adolescent and young adult couples. Method Participants were 296 pregnant young females (mean age = 18.7) and their male partners (mean age = 21.3; 592 total participants) who were recruited from obstetrics and gynecology clinics in Connecticut. The dimensions of avoidant and anxious romantic attachment were assessed using the Experiences in Close Relationships Inventory. Depressive symptoms were measured using the Center for Epidemiological Studies-Depression Scale. Results Results showed that avoidant attachment and anxious attachment were significantly positively related to depressive symptoms. Multilevel modeling for partner effects revealed that anxious attachment and depressive symptoms in partners were significantly positively associated with depressive symptoms Conclusion Findings underscore the importance of considering couples-based approaches to supporting the transition to parenthood and developing the necessary self and relationship skills to manage attachment needs and relationship challenges.

Data from the Early Childhood Longitudinal Study--Kindergarten Cohort (ECLS-K) were used to test the hypothesis that approaches to learning (ATL) mediates the link between parental divorce and academic achievement. Fixed effects regression was utilized to test for mediation, and subsequent moderation analyses examining gender and age at time of divorce also were conducted. Results indicated that divorce was associated with less growth in test scores and that ATL mediated 18% and 12% of this association in reading and mathematics respectively. Parental divorce also was associated with larger negative effects for children who experienced divorce at an older age as well as for girls' mathematics test scores. These findings contribute to the understanding of the impact of parental divorce on children's academic achievement and underscore the importance of focusing on the variability of child outcomes following parental divorce.

Psychological contracts contain both relational and transactional elements, each of which is associated with unique characteristics. In the present research, the authors drew on these distinct qualities to develop and test hypotheses regarding differential employee reactions to underfulfillment, fulfillment, and overfulfillment of relational and transactional promises. Further, the authors extended their test of the theoretical distinctions between relational and transactional contracts by assessing the relevance of trust as a key underlying mechanism of relational and transactional psychological contract breach effects. Participants in this 3-wave longitudinal study included 342 full-time temporary employees. In support of existing theoretical distinctions, results indicated that employees reacted differently to varying levels of fulfillment of their relational and transactional contracts and that trust is a more central mechanism of relational, as opposed to transactional, psychological contract breach effects. These findings underscore L.S. Lambert, J. R. Edwards, and D. M. Cable's (2003) recent recommendation that the traditional conceptualization and study of psychological contract breach requires expansion.

For individuals with chronic pain, the within-person influence of affect and goal cognition on daily work-related goal striving is not yet well understood. The present study tested the hypothesis that anticipatory goal cognition in the form of a morning work goal schema mediates the relations between morning affect and later (afternoon and evening) work goal striving. Working adults with chronic pain (N = 131) completed a 21-day diary with morning, afternoon, and evening assessments analyzed via multi-level structural equation modeling. At the within-person level, morning positive and negative affect were positively associated with morning work goal schemas; and morning work goal schemas, in turn, positively predicted both afternoon and evening work goal striving. Our findings underscore the complex dynamics over time of the relationship between affect and self-regulatory processes and have implications for future studies and for interventions to assist working adults with chronic pain.

Communication is a cooperative endeavor that goes well beyond decoding sentences' literal meaning. Listeners actively construe the meaning of utterances from both their literal meanings and the pragmatic principles that govern communication. When communicators make pragmatically infelicitous statements, the effects can be similar to paltering-misleading speech that evokes false inferences from true statements. The American Diabetes Association's (ADA's) "Diabetes Myths" website provides a real-world case study in such misleading communications. Calling something a myth implies that it is clearly false. Instead, the ADA's "myths" are false only because of some technicality or uncharitable reading. We compared participants' baseline knowledge of diabetes with that of participants who read either the ADA's myths or the myths rewritten as questions that do not presuppose the statement is false. As predicted, exposure to the ADA's "myths," but not to the rephrased questions, reduced basic knowledge of diabetes. Our findings underscore the need to consider psycholinguistic principles in mass communications.
The cross-cultural variation of predictors of human papillomavirus vaccination intentions.
Lechuga, Julia; Swain, Geoffrey R; Weinhardt, Lance S
2011-02-01
The influence of health beliefs on human papillomavirus (HPV) vaccine acceptability have been extensively documented in past research. However, studies documenting the generalizability of prior findings to culturally diverse participants are lacking. The importance of generalizability studies is underscored by the immense disparities in cervical cancer rates across ethnicities. Moreover, theory in cultural psychology suggests that beliefs derived from personal expectations may not be the strongest predictors of intentions in individuals socialized in collectivist cultures. The purpose of this research was to investigate the strongest predictors of mothers' intentions to vaccinate their daughters across three cultural groups: Hispanic, non-Hispanic white, and African American. One hundred fifty mothers were recruited from Public Health Department clinics in Milwaukee, Wisconsin. Mothers were asked to answer measures that assessed personal and normative predictors of intentions. Results indicated that predictors of vaccination intentions varied cross-culturally. Specifically, culture moderated the influence of norms on intentions. Interventions designed for Hispanics may be more effective if norms, rather than attitudes, are targeted.
The association between family factors and child behaviour problems using dyadic data.

Parental psychopathology and family issues are key influence factors to child behaviour problems. This study aimed to investigate the dyadic impact of maternal and paternal depression and perceived family functioning on child behaviour problems. Both maternal and paternal depression, perceived family functioning and reported child behaviour problems were collected, respectively. Because of the interdependent characteristic of dyadic data, structural equation modelling was used to examine the relationship among all variables and the mutual influence between mother and father. Results showed that father-perceived family functioning mediated the relationship between parental depression and child behaviour problems, but mother-perceived family functioning did not show this mediation effect. Meanwhile, maternal and paternal depression influenced both of their own and their partner's perceived family functioning. The findings indicated that paternal psychopathology and family functioning should not be overlooked in child behaviour development. In addition, this study underscored the importance to investigate the different impact of father and mother on child development within a dyadic unit. © 2014 John Wiley & Sons Ltd.
How to stomach an epigenetic insult: the gastric cancer epigenome.
Padmanabhan, Nisha; Ushijima, Toshikazu; Tan, Patrick
2017-08-01
Gastric cancer is a deadly malignancy afflicting close to a million people worldwide. Patient survival is poor and largely due to late diagnosis and suboptimal therapies. Disease heterogeneity is a substantial obstacle, underscoring the need for precision treatment strategies. Studies have identified different subgroups of gastric cancer displaying not just genetic, but also distinct epigenetic hallmarks. Accumulating evidence suggests that epigenetic abnormalities in gastric cancer are not mere bystander events, but rather promote carcinogenesis through active mechanisms. Epigenetic aberrations, induced by pathogens such as Helicobacter pylori, are an early component of gastric carcinogenesis, probably preceding genetic abnormalities. This Review summarizes our current understanding of the gastric cancer epigenome, highlighting key advances in recent years in both tumours and pre-malignant lesions, made possible through targeted and genome-wide technologies. We focus on studies related to DNA methylation and histone modifications, linking these findings to potential therapeutic opportunities. Lessons learned from the gastric cancer epigenome might also prove relevant for other gastrointestinal cancers.

Theory underscores the importance of parenting in sleep development, but few studies have examined whether links vary by temperament. To address this gap, we tested whether potential links between early maternal sensitivity and early adolescent sleep problems varied by child negative emotionality and delay of gratification. Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 820), we found that high maternal sensitivity predicted fewer bedtime problems and longer sleep duration at 6th grade for toddlers with high negative emotionality, whereas low maternal sensitivity predicted the reverse. No differences were observed for low negative emotionality. Moreover, delay of gratification predicted fewer bedtime problems at 6th grade, but did not moderate associations between maternal sensitivity, negative emotionality, and sleep. Findings demonstrate that high, but not low, negative emotionality renders toddlers differentially susceptible and receptive to maternal sensitivity in relation to sleep.

Gleason Score (GS) is a validated predictor of prostate cancer (PCa) disease progression and outcomes. GS from invasive needle biopsies suffers from significant inter-observer variability and possible sampling error, leading to underestimating disease severity ("underscoring") and can result in possible complications. A robust non-invasive image-based approach is, therefore, needed. Use spatially registered multi-parametric MRI (MP-MRI), signatures, and supervised target detection algorithms (STDA) to non-invasively GS PCa at the voxel level. This study retrospectively analyzed 26 MP-MRI from The Cancer Imaging Archive. The MP-MRI (T2, Diffusion Weighted, Dynamic Contrast Enhanced) were spatially registered to each other, combined into stacks, and stitched together to form hypercubes. Multi-parametric (or multi-spectral) signatures derived from a training set of registered MP-MRI were transformed using statistics-based Whitening-Dewhitening (WD). Transformed signatures were inserted into STDA (having conical decision surfaces) applied to registered MP-MRI determined the tumor GS. The MRI-derived GS was quantitatively compared to the pathologist's assessment of the histology of sectioned whole mount prostates from patients who underwent radical prostatectomy. In addition, a meta-analysis of 17 studies of needle biopsy determined GS with confusion matrices and was compared to the MRI-determined GS. STDA and histology determined GS are highly correlated (R = 0.86, p < 0.02). STDA more accurately determined GS and reduced GS underscoring of PCa relative to needle biopsy as summarized by meta-analysis (p < 0.05). This pilot study found registered MP-MRI, STDA, and WD transforms of signatures shows promise in non-invasively GS PCa and reducing underscoring with high spatial resolution.

Both discrimination and sexual health disparities have significant negative health implications for Latina/o preadolescent youth, including negative mental health outcomes, STIs/HIV, unintended pregnancy, and ongoing poverty. Studying these links within this population, therefore, has significant public health relevance, both in terms of promoting sexual health in general as well as serving the specific needs of Latina/o youth. This study explored the relationship between perceived discrimination, peer influence and sexual behaviors among 438 Mexican American preadolescents in the Southwest United States (55.3 % male). Additionally, this study examined whether psychological distress, substance use, and sexual motives mediated and whether gender moderated these relations. A multiple-group path analysis of the analytical model was performed to examine the hypothesized relations between perceived discrimination, peer influence, psychological distress, substance use, sexual motives and sexual behaviors. The findings indicated that perceived discrimination was directly linked to sexual behaviors among participants and indirectly linked via substance use. The findings also indicated that peer influence was indirectly linked to sexual behaviors via substance use among participants and via sexual motives among boys. This study underscores the importance of substance use in the perceived discrimination, peer influence and sexual behavior link in Mexican American preadolescents. Additionally, it highlights the importance of sexual motives in the link between peer influence and sexual behaviors of Mexican American boys.
Alcohol in the life narratives of women: Commonalities and differences by sexual orientation
Trocki, Karen F.
2013-01-01
Aim The aim of this study was to explore social representations of alcohol use among women, with a focus on possible differences between sexual minority and heterosexual women. Methods This qualitative study was part of a larger study examining mediators of heavier drinking among sexual minority women (lesbian identified, bisexual identified, and heterosexual identified with same sex partners) compared to heterosexual women based on the National Alcohol Survey. Qualitative in-depth life history interviews were conducted over the telephone with 48 women who had participated in the 2009–2010 National Alcohol Survey, including respondents representing different sexual orientation groups. Questions explored the lives and experiences of women, and how use of alcohol may connect to those experiences. Findings Representations about normative and risky use included social use, use in relation to community connection, addictive use and self-medication. Other representations common across groups included articulation of boundaries that were defined by negative exemplars, marked by indicators of loss of control, and maintained through selective engagement of social networks. Although representations across groups were similar, some representations, such as alcohol use in fostering community connection, appeared to be more salient for sexual minority women. The findings of the study underscore the importance of considering both commonalities and potential differences among women by sexual orientation in meanings and perceived risks associated with alcohol use in future research and intervention efforts.

The present longitudinal study examined the reliability of self-reported academic grades across three phases in four subject domains for a sample of 916 high-school students. Self-reported grades were found to be highly positively correlated with actual grades in all academic subjects and across grades 9 to 11 underscoring the reliability of self-reported grades as an achievement indicator. Reliability of self-reported grades was found to differ across subject areas (e.g., mathematics self-reports more reliable than language studies), with a slight yet consistent tendency to over-report achievement levels also observed across grade levels and academic subjects. Overall, the absolute value of over- and underreporting was low and these patterns were not found to differ between mathematics and verbal subjects. In sum, study findings demonstrate the consistent predictive utility of students' self-reported achievement across grade levels and subject areas with the observed tendency to over-report academic grades and slight differences between domains nonetheless warranting consideration in future education research.

Perceived live interaction modulates the developing social brain.
Rice, Katherine; Moraczewski, Dustin; Redcay, Elizabeth
2016-09-01
Although children's social development is embedded in social interaction, most developmental neuroscience studies have examined responses to non-interactive social stimuli (e.g. photographs of faces). The neural mechanisms of real-world social behavior are of special interest during middle childhood (roughly ages 7-13), a time of increased social complexity and competence coinciding with structural and functional social brain development. Evidence from adult neuroscience studies suggests that social interaction may alter neural processing, but no neuroimaging studies in children have directly examined the effects of live social-interactive context on social cognition. In the current study of middle childhood, we compare the processing of two types of speech: speech that children believed was presented over a real-time audio-feed by a social partner and speech that they believed was recorded. Although in reality all speech was prerecorded, perceived live speech resulted in significantly greater neural activation in regions associated with social cognitive processing. These findings underscore the importance of using ecologically-valid and interactive methods to understand the developing social brain. © The Author (2016). Published by Oxford University Press.

Objective: To evaluate the utility of targeted exome sequencing for the molecular diagnosis of mitochondrial disorders, which exhibit marked phenotypic and genetic heterogeneity. Methods: We considered a diverse set of 102 patients with suspected mitochondrial disorders based on clinical, biochemical, and/or molecular findings, and whose disease ranged from mild to severe, with varying age at onset. We sequenced the mitochondrial genome (mtDNA) and the exons of 1,598 nuclear-encoded genes implicated in mitochondrial biology, mitochondrial disease, or monogenic disorders with phenotypic overlap. We prioritized variants likely to underlie disease and established molecular diagnoses in accordance with current clinical genetic guidelines. Results: Targeted exome sequencing yielded molecular diagnoses in established disease loci in 22% of cases, including 17 of 18 (94%) with prior molecular diagnoses and 5 of 84 (6%) without. The 5 new diagnoses implicated 2 genes associated with canonical mitochondrial disorders (NDUFV1, POLG2), and 3 genes known to underlie other neurologic disorders (DPYD, KARS, WFS1), underscoring the phenotypic and biochemical overlap with other inborn errors. We prioritized variants in an additional 26 patients, including recessive, X-linked, and mtDNA variants that were enriched 2-fold over background and await further support of pathogenicity. In one case, we modeled patient mutations in yeast to provide evidence that recessive mutations in ATP5A1 can underlie combined respiratory chain deficiency. Conclusion: The results demonstrate that targeted exome sequencing is an effective alternative to the sequential testing of mtDNA and individual nuclear genes as part of the investigation of mitochondrial disease. Our study underscores the ongoing challenge of variant interpretation in the clinical setting. PMID:23596069

The habenula is a small, mostly underrated structure in the pineal region. Multidisciplinary findings demonstrate an underlying complex connectivity of the habenula with the rest of the brain, subserving its major role in normal behavior and the pathophysiology of depression. These findings suggest the potential application of "habenular psychosurgery" in the treatment of mental disorders. The remission of two patients with treatment-resistant major depression treated with deep brain stimulation of the habenula supported the hypothesis that the habenula is an effective target for deep brain stimulation and initiated a surge of basic science research. This review aims to assess the viability of the deep brain stimulation of the habenula as a treatment option for treatment resistant depression. PubMed and the Cochrane Library databases were searched with no chronological restrictions for the identification of relevant articles. The results of this review are presented in a narrative form describing the functional neuroanatomy of the human habenula, its implications in major depression, findings of electrode implantation of this region and findings of deep brain stimulation of the habenula for the treatment of depression. Data assessing the hypothesis are scarce. Nonetheless, findings highlight the major role of the habenula in normal, as well as in pathological brain function, particularly in depression disorders. Moreover, findings of studies utilizing electrode implantation in the region of the habenula underscore our growing realization that research in neuroscience and deep brain stimulation complement each other in a reciprocal relationship; they are as self-reliant, as much as they depend on each other.

Aging Filipino Domestic Workers and the (In)Adequacy of Retirement Provisions in Canada.
Ferrer, Ilyan
2017-03-01
Although domestic work scholarship in Canada has focused primarily on the immigration/migration and labour experiences of domestic workers under the Foreign Domestic Movement and the Live-in-Caregiver Program, research is scarce on how these workers retire and consequently age in Canadian society. This article focuses on the aging experiences of retired Filipino domestic workers who, upon entering retirement, find themselves working in the secondary and/or underground economy while providing and receiving care from spouses, grandchildren, and local/transnational family members. Data were drawn from six qualitative, in-depth interviews with older Filipina domestic workers who discussed experiences of immigration, caring labour, retirement, and aging. Findings underscore (1) the poverty that older Filipino domestic workers encounter as they approach their retirement; (2) the necessity but insufficiency of the state's retirement provisions; (3) the need to find work in the unreported labour market; and (4) how caring labour is provided intergenerationally as a survival strategy.

fMRI studies of successful emotional memory encoding: a quantitative meta-analysis
Murty, Vishnu P.; Ritchey, Maureen; Adcock, R. Alison; LaBar, Kevin S.
2010-01-01
Over the past decade, fMRI techniques have been increasingly used to interrogate the neural correlates of successful emotional memory encoding. These investigations have typically aimed to either characterize the contributions of the amygdala and medial temporal lobe (MTL) memory system, replicating results in animals, or delineate the neural correlates of specific behavioral phenomena. It has remained difficult, however, to synthesize these findings into a systems neuroscience account of how networks across the whole brain support the enhancing effects of emotion on memory encoding. To this end, the present study employed a meta-analytic approach using activation likelihood estimates to assess the anatomical specificity and reliability of event-related fMRI activations related to successful memory encoding for emotional versus neutral information. The meta-analysis revealed consistent clusters within bilateral amygdala, anterior hippocampus, anterior and posterior parahippocampal gyrus, the ventral visual stream, left lateral prefrontal cortex and right ventral parietal cortex. The results within the amygdala and MTL support a wealth of findings from the animal literature linking these regions to arousal-mediated memory effects. The consistency of findings in cortical targets, including the visual, prefrontal, and parietal cortices, underscores the importance of generating hypotheses regarding their participation in emotional memory formation. In particular, we propose that the amygdala interacts with these structures to promote enhancements in perceptual processing, semantic elaboration, and attention, which serve to benefit subsequent memory for emotional material. These findings may motivate future research on emotional modulation of widespread neural systems and the implications of this modulation for cognition. PMID:20688087

Data on 7,424 soldier spouse abuse offenders were analyzed to determine the prevalence of substance use during abusive incidents, and to examine differences between substance-using and non-substance-using offenders. Results showed that 25% of all offenders used substances during abusive incidents, with males and non-Hispanic Whites being more likely to hav e used substances. Substance-using offenders were more likely to perpetrate physical spouse abuse and more severe spouse abuse. These findings underscore the importance of educating military personnel (including commanders) about links between substance use and domestic violence, and of coordinating preventive and therapeutic substance abuse and violence-related interventions.
Believing is seeing: an evolving research program on patients' psychotherapy expectations.
Constantino, Michael J
2012-01-01
In this article I discuss one facet of my evolving research program focused on patients' psychotherapy-related expectations. Although generally considered a common psychotherapeutic factor, expectations have been historically undervalued conceptually, empirically, and clinically. Attempting to somewhat redress this slight, I will (a) define the various forms of patients' psychotherapy-related expectations, (b) present relevant findings from research that my colleagues, students, and I have conducted, (c) summarize an integrative psychotherapy approach that underscores expectations as an explanatory construct for patients' corrective experiences, and (d) highlight future research directions for increasing our understanding of the nature and functions of the expectancy construct.

This article explores the experiences of a small group of Nairobi women caring for a family cancer patient at home. On the basis of literature on women as caregivers in Africa, and on other literature more broadly, it was anticipated that issues around generational roles, gender and women's cultural role would be relevant. Seven women participated in semi-structured in-depth interviews, while thirteen women participated in four mini focus groups. Data were analysed using interpretative phenomenological analysis. Findings underscore the socio-cultural complexities of caregiving as a basis for evidence-based culturally appropriate structures to support family caregivers.
Young, black, and connected: Facebook usage among African American college students.
Lee, E Bun
2012-01-01
This article examines the extent and intensity of Facebook usage among African American college students and investigates their reasons for using Facebook. As expected, 98% of students in the survey had a Facebook account, and a large number of Facebook “friends.” Younger users spent significantly more time on Facebook than older ones. Our findings underscore the importance of cultural influence for African American online users. Displaying photographs and personal interests on Facebook signals racial identity among African American college students. Personality traits, such as self-esteem, trust in people, satisfaction with university life, and racial identity, were not significant predictors on the time spent on Facebook.
Troglomorphism in the middle Triassic crinoids from Poland.
Brom, Krzysztof R; Brachaniec, Tomasz; Salamon, Mariusz A
2015-10-01
In this paper, we document the Middle Triassic marine fauna recovered from the fissure/cave system of Stare Gliny (southern Poland) developed in the Devonian host dolomite. The fossils are mostly represented by in situ preserved and small-sized holdfasts of crinoids (Crinoidea) that are attached to the cave walls. Other fossils found in the cave infills include articulated brittle stars and brachiopods. Our findings constitute the oldest Mesozoic evidence for troglophile crinoids. We suggest that troglomorphism in these echinoderms was likely related to protection against predation, which underscores the magnitude of anti-predatory adaptations to increased predation pressure that occurred during the Early Mesozoic Marine Revolution.

Using longitudinal student data from 15 four-year (n = 3,072) and 13 (n = 788) two-year postsecondary institutions, the authors tested the effects of interest-major congruence, motivation, and 1st-year academic performance on timely degree completion. Findings suggest that interest-major congruence has a direct effect on timely degree completion at both institutional settings and that motivation has indirect effects (via 1st-year academic performance). The total effects of both interest-major congruence and motivation on timely degree completion underscore the importance of both constructs in understanding student adjustment and postsecondary success. Implications for theory and counseling practice are discussed.
Transition into first sex among adolescents in slum and non-slum communities in Nairobi, Kenya
Kabiru, Caroline W.; Beguy, Donatien; Undie, Chi-Chi; Zulu, Eliya Msiyaphazi; Ezeh, Alex C.
2014-01-01
While early sexual experiences are a key marker of the transition from childhood to adulthood, it is widely acknowledged that precocious initiation of sexual activity predisposes adolescents to negative health and psychological outcomes. Extant studies investigating adolescent sexuality in sub-Saharan Africa often rely on cross-sectional data lacking information on the social-psychological underpinnings of adolescent behavior. Through the theoretical lens of the protection-risk conceptual framework, this paper draws on two waves of longitudinal data collected from 2,134 adolescents to examine sociodemographic, psychosocial and behavioral predictors of transition to first sex among adolescents living in slum and non-slum settlements in urban Kenya. We employ logistic regression models to examine the effect of antecedent sociodemographic and risk and protective factors measured during the first wave of data collection on transition to first sex by the second wave. We observe that transition to first sex is influenced by age, slum residence, perceived parental monitoring, and peer behavior. We also find evidence for coupling of risk behaviors. Study findings underscore the need to focus on very young adolescents and those growing up in resource poor settings as these young people may be highly vulnerable to negative health outcomes stemming from precocious sexual activity.

Objectives. The current study examined how a key component of caregiving stress processes, global mastery perceptions, changes with placing the care recipient in a nursing home or institution. We also explored the role of primary stressors in accounting for mastery changes with placement and whether characteristics of the caregiver and care recipient moderate reactions to placement. Method. We applied multiphase growth curve models to prospective longitudinal data from 271 caregivers in the Caregiver Stress and Coping Study who experienced placement of their care recipient. Results. Using a time-to/from-placement metric, we found that caregivers typically experienced declines in mastery preceding placement, followed by a significant increase within 1 year after placement and further increases thereafter. Corresponding changes in primary stressors (role overload) mediated the placement-related increase in mastery. Caregivers who reported more depressive symptoms and activities of daily living/instrumental activities of daily living dependencies of the care recipient were more likely to experience larger placement-related increases in mastery perceptions. Discussion. Our findings suggest that placement alters psychological resources of caregivers and this effect is driven by corresponding changes in primary stressors. Findings also underscore the importance of examining change processes across salient life events and transitions. PMID:22956053

A worldwide epidemic of type 2 diabetes mellitus (T2DM) is in progress. This disease carries a heavy socioeconomic burden. To compare the incidence rate of overall and site-specific cancers among Israeli Arabs with T2DM to that of Israeli Arabs without. A retrospective cohort study of all adult Arab members of Clalit Health Care Services in northern Israel was conducted over a 10 year period (1999-2008). During the study period 752 and 2045 incident cases of cancer were diagnosed among 13,450 adults with diabetes and 74,484 without, respectively. The follow-up time involved 817,506 person-years. Diabetes was associated with a standard incidence ratio (SIR) of 3.27 (95% CI 1.49-5.05) and 2.87 (95% CI 1.25-4.50) for pancreatic cancer in men and women, respectively. A significantly reduced SIR (0.67, 95% CI 0.36-0.99) was observed for esophageal, stomach and intestinal cancers in men. Our findings support an association between T2DM and increased risk of cancer of the pancreas in Arab men and women. A significantly reduced risk of all other cancers was observed only in Arab men. Our findings underscore the need for effective diabetes and cancer prevention and intervention programs.

This study examined whether the social networks of older persons in Mediterranean and non-Mediterranean countries were appreciably different and whether they functioned in similar ways in relation to well-being outcomes. The sample included family household respondents aged 60 years and older from the first wave of the Survey of Health, Ageing and Retirement in Europe in 5 Mediterranean (n = 3,583) and 7 non-Mediterranean (n = 5,471) countries. Region was regressed separately by gender on variables from 4 network domains: structure and interaction, exchange, engagement and relationship quality, and controlling for background and health characteristics. In addition, 2 well-being outcomes-depressive symptoms and perceived income inadequacy-were regressed on the study variables, including regional social network interaction terms. The results revealed differences across the 2 regional settings in each of the realms of social network, above and beyond the differences that exist in background characteristics and health status. The findings also showed that the social network variables had different effects on the well-being outcomes in the respective settings. The findings underscore that the social network phenomenon is contextually bound. The social networks of older people should be seen within their unique regional milieu and in relation to the values and social norms that prevail in different sets of societies.

Psychosocial factors, including job demands and poor resources, have been linked to stress, health problems, and negative job attitudes. However, worksite based interventions and programs targeting psychosocial factors may change employees' perceptions of their work climate and work attitudes. This pilot study describes a newly developed worksite based participatory organizational intervention program that was tested in the social service sector. It is evaluated using participants' perceptions of the intervention to investigate its acceptability as a feature of feasibility and its short-term effects on work climate factors (job demands and resources) and work-related attitudes. Forty employees of a Swedish social service unit provided self-reports before, during, and after the intervention. As for effects, quantitative role overload and social support decreased while turnover intention increased. Responses to an open-ended question showed that participants considered the intervention program valuable for addressing issues relating to the psychosocial work climate. Although the findings are preliminary, it was possible to carry out this worksite based participatory organizational program in this particular setting. Also, the preliminary findings underscore the challenges associated with designing and implementing this type of intervention program, thus adding to the methodological discussion on implementation and evaluation.
Marital formation in individuals with work-related permanent impairment.
Scott-Marshall, Heather; Tompa, Emile; Liao, Qing; Fang, Miao
2013-01-01
Prior studies on the impact of disabling work injury have neglected social support as a key mediating factor. This study investigates how permanent impairment from a work injury affects marital formation, an indicator of social support and integration with the potential to affect psychosocial adjustment and the resumption of productive social roles following work injury. Adjusting for socio-demographic and economic factors associated with marriage ability, we expect that individuals with a work-related permanent impairment will have a lower rate of marital formation compared to their non-injured counterparts. Drawing on a linkage of workers' compensation claims data with income tax information, we undertake a duration modeling analysis comparing workers who have sustained a workplace injury with a matched sample of non-injured controls to examine time to marital formation in each group. Women who suffered a disabling work injury were 17% less likely to marry relative to controls. High levels of physical impairment reduced the rate of marriage in women by 22%. We did not find an effect of impairment on marriage probability in models adjusted for income in men. Our findings underscore the importance of examining the social and interpersonal consequences of work injury, factors not currently addressed by the occupational rehabilitation system.

Income inequality and obesity prevalence among OECD countries.
Su, Dejun; Esqueda, Omar A; Li, Lifeng; Pagán, José A
2012-07-01
Using recent pooled data from the World Health Organization Global Infobase and the World Factbook compiled by the Central Intelligence Agency of the United States, this study assesses the relation between income inequality and obesity prevalence among 31 OECD countries through a series of bivariate and multivariate linear regressions. The United States and Mexico well lead OECD countries in both obesity prevalence and income inequality. A sensitivity analysis suggests that the inclusion or exclusion of these two extreme cases can fundamentally change the findings. When the two countries are included, the results reveal a positive correlation between income inequality and obesity prevalence. This correlation is more salient among females than among males. Income inequality alone is associated with 16% and 35% of the variations in male and female obesity rates, respectively, across OECD countries in 2010. Higher levels of income inequality in the 2005-2010 period were associated with a more rapid increase in obesity prevalence from 2002 to 2010. These associations, however, virtually disappear when the US and Mexico have been excluded from the analysis. Findings from this study underscore the importance of assessing the impact of extreme cases on the relation between income inequality and health outcomes. The potential pathways from income inequality to the alarmingly high rates of obesity in the cases of the US and Mexico warrant further research.

With the aim of investigating gender differences in the functional lateralization subserving preattentive processing of language stimuli, we compared auditory mismatch negativities (MMNs) using dichotic listening tasks. Forty-four healthy volunteers, including 23 males and 21 females, participated in the study. MMNs generated by pure-tone and phonetic stimuli were compared, to check for the existence of language-specific gender differences in lateralization. Both EEG amplitude and scalp current density (SCD) data were analyzed. With phonetic MMNs, EEG findings revealed significantly larger amplitude in females than males, especially in the right hemisphere, while SCD findings revealed left hemisphere dominance and contralateral dominance in males alone. With pure-tone MMNs, no significant gender differences in hemispheric lateralization appeared in either EEG or SCD findings. While males exhibited left-lateralized activation with phonetic MMNs, females exhibited more bilateral activity. Further, the contralateral dominance of the SCD distribution associated with the ear receiving deviant stimuli in males indicated that ipsilateral input as well as interhemispheric transfer across the corpus callosum to the ipsilateral side was more suppressed in males than in females. The findings of the present study suggest that functional lateralization subserving preattentive detection of phonetic change differs between the genders. These results underscore the significance of considering the gender differences in the study of MMN, especially when phonetic stimulus is adopted. Moreover, they support the view of Voyer and Flight [Voyer, D., Flight, J., 2001. Gender differences in laterality on a dichotic task: the influence of report strategies. Cortex 37, 345-362.] in that the gender difference in hemispheric lateralization of language function is observed in a well-managed-attention condition, which fits the condition adopted in the MMN measurement; subjects are required to focus attention to a distraction task and thereby ignore the phonetic stimuli that elicit MMN.

Converging preclinical and human evidence indicates that the decline in ovarian estradiol production during the menopausal transition may play a mechanistic role in the neuronal changes that occur early in the aging process. Here, we present findings from a population-based fMRI study characterizing regional and network-level differences in working memory (WM) circuitry in midlife men and women (N = 142; age range 46-53), as a function of sex and reproductive stage. Reproductive histories and hormonal evaluations were used to determine menopausal status. Participants performed a verbal WM task during fMRI scanning. Results revealed robust differences in task-evoked responses in dorsolateral prefrontal cortex and hippocampus as a function of women's reproductive stage, despite minimal variance in chronological age. Sex differences in regional activity and functional connectivity that were pronounced between men and premenopausal women were diminished for postmenopausal women. Critically, analyzing data without regard to sex or reproductive status obscured group differences in the circuit-level neural strategies associated with successful working memory performance. These findings underscore the importance of reproductive age and hormonal status, over and above chronological age, for understanding sex differences in the aging of memory circuitry. Further, these findings suggest that early changes in working memory circuitry are evident decades before the age range typically targeted in cognitive aging studies. © The Author 2016.

The technique of threshold tracking to test axonal excitability gives information about nodal and internodal ion channel function. We aimed to investigate variability of the motor excitability measurements in healthy controls, taking into account age, gender, body mass index (BMI) and small changes in skin temperature. We examined the left median nerve of 47 healthy controls using the automated threshold-tacking program, QTRAC. Statistical multiple regression analysis was applied to test relationship between nerve excitability measurements and subject variables. Comparisons between genders did not find any significant difference (P>0.2 for all comparisons). Multiple regression analysis showed that motor amplitude decreases with age and temperature, stimulus-response slope decreases with age and BMI, and that accommodation half-time decrease with age and temperature. The changes related to demographic features on TRONDE protocol parameters are small and less important than in conventional nerve conduction studies. Nonetheless, our results underscore the relevance of careful temperature control, and indicate that interpretation of stimulus-response slope and accommodation half-time should take into account age and BMI. In contrast, gender is not of major relevance to axonal threshold findings in motor nerves. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Neural progenitors typically divide asymmetrically to renew themselves, while producing daughters with more limited potential. In the Drosophila embryonic ventral nerve cord, neuroblasts initially produce daughters that divide once to generate two neurons/glia (type I proliferation mode). Subsequently, many neuroblasts switch to generating daughters that differentiate directly (type 0). This programmed type I>0 switch is controlled by Notch signaling, triggered at a distinct point of lineage progression in each neuroblast. However, how Notch signaling onset is gated was unclear. We recently identified Sequoia (Seq), a C2H2 zinc-finger transcription factor with homology to Drosophila Tramtrack (Ttk) and the positive regulatory domain (PRDM) family, as important for lineage progression. Here, we find that seq mutants fail to execute the type I>0 daughter proliferation switch and also display increased neuroblast proliferation. Genetic interaction studies reveal that seq interacts with the Notch pathway, and seq furthermore affects expression of a Notch pathway reporter. These findings suggest that seq may act as a context-dependent regulator of Notch signaling, and underscore the growing connection between Seq, Ttk, the PRDM family and Notch signaling. © 2016.

Age, psychological skills, and golf performance: a prospective investigation.
Hayslip, Bert; Petrie, Trent A
2014-03-01
This study explored the influence of age in understanding mental skills utilization in the context of performance at a major national golf competition. Participants, who ranged in age and in skill level, included 1150 male and 170 female amateur golfers competing in the Dupont World Amateur Golf Championship in Myrtle Beach, South Carolina. Measures targeted general mental skills used in competitions, golf-specific skills, and competitive trait anxiety. Hierarchical linear regression was utilized to explore the potential moderating role that chronological age may play in influencing the impact of psychological skills and anxiety on competitive tournament performance across the adult life span. Findings suggested no significant age-moderating effects and instead pointed to the importance of developing golf-specific psychological skills to enhance or maintain performance, irrespective of age. Although automaticity (performance feels "automatic") predicted performance for all golfers, commitment to the game and confidence in one's putting did so only for the men. These findings reinforce the age-irrelevant role of such skills in fostering the experience of peak performance in a competitive sport context and underscore the importance of interventions targeting older players to help maintain or facilitate the use of psychological skills in helping them manage their games.

Anxiety disorders are collectively the most prevalent mental health problems affecting youth. To increase the reach of mental health care, recent years have seen increasing enthusiasm surrounding mobile platforms for expanding treatment delivery options. Apps developed in academia and supported in clinical trials are slow to reach the consumer marketplace. Meanwhile, proliferation of industry-developed apps on consumer marketplaces has been high. The present study analyzed content within mobile products prominently marketed toward consumers for anxiety in youth. Systematic inventory of the Google Play Store and Apple Store using keyword searches for child and adolescent anxiety yielded 121 apps, which were evaluated on the basis of their descriptive characteristics, mobile functionalities, and adherence to evidence-based treatment principles. Findings revealed that evidence-based treatment content within the sample is scant and few comprehensive anxiety self-management apps were identified. Advanced features that leverage the broader functionalities of smartphone capabilities (e.g., sensors, ecological momentary assessments) were rarely present. Findings underscore the need to increase the prominence and accessibility of quality child anxiety intervention products for consumers. Strategies for improving marketing of supported apps to better penetrate consumer markets are discussed. Copyright © 2017. Published by Elsevier Ltd.
Climate Variability and Inter-Provincial Migration in South America, 1970-2011
Thiede, Brian; Gray, Clark; Mueller, Valerie
2016-01-01
We examine the effect of climate variability on human migration in South America. Our analyses draw on over 21 million observations of adults aged 15-40 from 25 censuses conducted in eight South American countries. Addressing limitations associated with methodological diversity among prior studies, we apply a common analytic approach and uniform definitions of migration and climate across all countries. We estimate the effects of climate variability on migration overall and also investigate heterogeneity across sex, age, and socioeconomic groups, across countries, and across historical climate conditions. We also disaggregate migration by the rural/urban status of destination. We find that exposure to monthly temperature shocks has the most consistent effects on migration relative to monthly rainfall shocks and gradual changes in climate over multi-year periods. We also find evidence of heterogeneity across demographic groups and countries. Analyses that disaggregate migration by the rural/urban status of destination suggest that much of the climate-related inter-province migration is directed toward urban areas. Overall, our results underscore the complexity of environment-migration linkages and challenge simplistic narratives that envision a linear and monolithic migratory response to changing climates.

Based on the Dual Systems Model (Somerville et al., 2010; Steinberg, 2010a) and the biosocial-affect model (Romer and Hennessy, 2007) of adolescent sensation seeking and problem behaviors, the present study examined how (affective associations with online games as a mediator) and when (impulsivity as a moderator) did sensation seeking influence online gaming addiction in adolescence. A total of 375 Chinese male adolescents (mean age = 16.02 years, SD = 0.85) from southern China completed anonymous questionnaires regarding sensation seeking, positive affective associations with online games, impulsivity, and online gaming addiction. Our findings revealed that sensation seeking, positive affective associations with online games and impulsivity were each significantly and positively associated with online gaming addiction in adolescents. Positive affective associations mediated the relationship between sensation seeking and online gaming addiction. Further, impulsivity moderated the relationship between positive affective associations and online gaming addiction, such that the association between positive affective association and online gaming addiction was stronger for high than for low impulsivity adolescents. These findings underscore the importance of integrating the biosocial-affect model and the Dual Systems Model to understand how and when sensation seeking impacts adolescent online gaming addiction.
Susceptibility to misleading information under social pressure in schizophrenia.

Research looking at specific memory aberrations in the schizophrenia has primarily focused on their phenomenology using standardized semantic laboratory tasks. However, no study has investigated to what extent such aberrations have consequences for everyday episodic memories using more realistic false memory paradigms. Using a false memory paradigm where participants are presented with misleading suggestive information (Gudjonsson Suggestibility Scale), we investigated the susceptibility of patients with schizophrenia (n = 21) and healthy controls (n = 18) to post hoc misleading information acceptance and compliance. Patients with schizophrenia exhibited an increased susceptibility to go along with misleading suggestive items. Furthermore, they showed an increased tendency to change answers under conditions of social pressure. Underscoring previous findings on memory aberrations in schizophrenia, patients with schizophrenia had reduced levels of correct recognition (ie, true memory) relative to healthy controls. The effects remained stable when controlling for specific mediating variables such as symptom severity and intelligence in patients with schizophrenia. These findings are a first indication that social pressure and misleading information may impair source memory for everyday episodic memories in schizophrenia, and such impairment has clear consequences for treatment issues and forensic practice.

Poor early life care often relates to cognitive difficulties. However, newer work suggests that in early-life, adversity may associate with enhanced or accelerated neurodevelopment. We examine associations between postnatal caregiving risks (i.e., higher self-reported postnatal-anxiety and lower observed maternal sensitivity) and infant relational memory (i.e. via deferred imitation and relational binding). Using subsamples of 67-181 infants (aged 433-477 post-conceptual days, or roughly five to seven months since birth) taking part in the GUSTO study, we found such postnatal caregiving risk significantly predictive of "better" performance on a relational binding task following a brief delay, after Bonferroni adjustments. Subsequent analyses suggest that the association between memory and these risks may specifically be apparent amongst infants spending at least 50% of their waking hours in the presence of their mothers. Our findings echo neuroimaging research concerning similar risk exposure and larger infant hippocampal volume, and likewise underscore the importance of considering developmental context in understanding early life experience. With this in mind, these findings caution against the use of cognitive outcomes as indices of experienced risk. This article is protected by copyright.

The structure-specific nuclease, Rad27p/FEN1, plays a crucial role in DNA repair and replication mechanisms in the nucleus. Genetic assays using the rad27-∆ mutant have shown altered rates of DNA recombination, microsatellite instability, and point mutation in mitochondria. In this study, we examined the role of Rad27p in mitochondrial mutagenesis and double-strand break (DSB) repair in Saccharomyces cerevisiae Our findings show that Rad27p is essential for efficient mitochondrial DSB repair by a pathway that generates deletions at a region flanked by direct repeat sequences. Mutant analysis suggests that both exonuclease and endonuclease activities of Rad27p are required for its role in mitochondrial DSB repair. In addition, we found that the nuclease activities of Rad27p are required for the prevention of mitochondrial DNA (mtDNA) point mutations, and in the generation of spontaneous mtDNA rearrangements. Overall, our findings underscore the importance of Rad27p in the maintenance of mtDNA, and demonstrate that it participates in multiple DNA repair pathways in mitochondria, unlinked to nuclear phenotypes.

Normative identity construction among women diagnosed with a gambling disorder.
Gavriel-Fried, Belle; Peled, Einat; Ajzenstadt, Mimi
2015-03-01
Women with a gambling problem bear a negative social stigma. Based on the theory of symbolic interactionism, this study examined the construction of social identities by 17 Israeli women diagnosed with a gambling disorder. Interpretive interactionist analysis revealed how they construct their identity through correspondence with patterns of behavior that are perceived as normative, and identified 3 major themes: "I'm not actually a gambler" (the presentation of a multidimensional identity comprising other identities besides that of a gambler); "Staying normative during gambling"; and "I have changed" (reformed gamblers' presentation of themselves as having changed for the better). The findings underscore the complex dialogue behind the identity construction put forward by women with a gambling problem, their yearning to be perceived by society as normative women and to fit in despite their stigmatized behavior, and the tension they feel in society's relationship toward them. The findings also suggest that practitioners who work with women gamblers may want to pay attention to the power relations shaping identity construction in an interview setting, and look more closely at the women's awareness of the stigma they bear and the complex processes that make up their multidimensional identity.

Genetic advances of type 2 diabetes in Chinese populations.
Yu, Weihui; Hu, Cheng; Jia, Weiping
2012-09-01
In recent decades, the prevalence of type 2 diabetes in China has increased significantly, underscoring the importance of investigating the etiological mechanisms, including genetic determinants, of the disease in Chinese populations. Numerous loci conferring susceptibility to type 2 diabetes (T2D) have been identified worldwide, with most having been identified in European populations. In terms of ethnic heterogeneity in pathogenesis as well as disease predisposition, it is imperative to explore the specific genetic architecture of T2D in Han Chinese. Replication studies of European-derived susceptibility loci have been performed, validating 11 of 32 loci in Chinese populations. Genetic investigations into heritable traits related to glucose metabolism are expected to provide new insights into the pathogenesis of T2D, and such studies have already inferred some new susceptibility loci. Other than replication studies of European-derived loci, efforts have been made to identify specific susceptibility loci in Chinese populations using methods such as genome-wide association studies. These efforts have identified additional new loci for the disease. Genetic studies can facilitate the prediction of risk for T2D and also promote individualized anti-diabetic treatment. Despite many advances in the field of risk prediction and pharmacogenetics, the pace of clinical application of these findings is rather slow. As a result, more studies into the practical utility of these findings remain necessary. © 2012 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.
Ratings for emotion film clips.
Gabert-Quillen, Crystal A; Bartolini, Ellen E; Abravanel, Benjamin T; Sanislow, Charles A
2015-09-01
Film clips are widely utilized to elicit emotion in a variety of research studies. Normative ratings for scenes selected for these purposes support the idea that selected clips correspond to the intended target emotion, but studies reporting normative ratings are limited. Using an ethnically diverse sample of college undergraduates, selected clips were rated for intensity, discreteness, valence, and arousal. Variables hypothesized to affect the perception of stimuli (i.e., gender, race-ethnicity, and familiarity) were also examined. Our analyses generally indicated that males reacted strongly to positively valenced film clips, whereas females reacted more strongly to negatively valenced film clips. Caucasian participants tended to react more strongly to the film clips, and we found some variation by race-ethnicity across target emotions. Finally, familiarity with the films tended to produce higher ratings for positively valenced film clips, and lower ratings for negatively valenced film clips. These findings provide normative ratings for a useful set of film clips for the study of emotion, and they underscore factors to be considered in research that utilizes scenes from film for emotion elicitation.
In vivo cell biology in zebrafish - providing insights into vertebrate development and disease.

Over the past decades, studies using zebrafish have significantly advanced our understanding of the cellular basis for development and human diseases. Zebrafish have rapidly developing transparent embryos that allow comprehensive imaging of embryogenesis combined with powerful genetic approaches. However, forward genetic screens in zebrafish have generated unanticipated findings that are mirrored by human genetic studies: disruption of genes implicated in basic cellular processes, such as protein secretion or cytoskeletal dynamics, causes discrete developmental or disease phenotypes. This is surprising because many processes that were assumed to be fundamental to the function and survival of all cell types appear instead to be regulated by cell-specific mechanisms. Such discoveries are facilitated by experiments in whole animals, where zebrafish provides an ideal model for visualization and manipulation of organelles and cellular processes in a live vertebrate. Here, we review well-characterized mutants and newly developed tools that underscore this notion. We focus on the secretory pathway and microtubule-based trafficking as illustrative examples of how studying cell biology in vivo using zebrafish has broadened our understanding of the role fundamental cellular processes play in embryogenesis and disease.

Although loneliness is a common problem across late adolescence, its developmental course has not been investigated in depth in this period of life. The present study aims to fill this gap by means of a five-wave cohort-sequential longitudinal study spanning ages 15 to 20 (N = 389). Both variable-centered (i.e., latent growth curve modeling) and person-centered (i.e., latent class growth analysis) approaches were used. Variable-centered analyses showed that loneliness generally decreased over time. Person-centered analyses pointed to considerable inter-individual differences in the development of loneliness, and identified five trajectory classes (i.e., stable low, low increasing, moderate decreasing, high increasing, and chronically high). These five trajectory classes were differentially related to personality traits at age 15 (i.e., extraversion, agreeableness, and emotional stability) and psychosocial functioning at age 20 (i.e., depressive symptoms, self-esteem, anxiety, and perceived stress). These findings underscore the additional value of studying subgroups regarding the development of loneliness. Copyright © 2012 The Foundation for Professionals in Services for Adolescents.

Studies demonstrate an association between sluggish cognitive tempo (SCT) and social impairment, although no studies have tested possible mechanisms of this association. This study aimed to (a) examine SCT in relation to college students' social functioning; (b) test if SCT is significantly associated with emotion dysregulation beyond depressive, anxious, and ADHD symptoms; and (c) test if emotion dysregulation mediates the association between SCT symptoms and social impairment. College students (N = 158) completed measures of psychopathology symptoms, emotion dysregulation, and social functioning. Participants with elevated SCT (12%) had higher ADHD, depressive, and anxious symptoms in addition to poorer emotion regulation and social adjustment than participants without elevated SCT. Above and beyond other psychopathologies, SCT was significantly associated with social impairment but not general interpersonal functioning. SCT was also associated with emotion dysregulation, even after accounting for the expectedly strong association between depression and emotion dysregulation. Further analyses supported emotion dysregulation as a mediator of the association between SCT and social impairment. These findings are important for theoretical models of SCT and underscore the need for additional, longitudinal research. © The Author(s) 2014.

Children's interactions with peers in early childhood have been consistently linked to their academic and social outcomes. Although both child and classroom characteristics have been implicated as contributors to children's success, there has been scant research linking child temperament, teacher-child relationship quality, and peer interactions in the same study. The purpose of this study is to examine children's early temperament, rated at preschool age, as a predictor of interactions with peers (i.e., aggression, relational aggression, victimization, and prosociality) in third grade while considering teacher-child relationship quality in kindergarten through second grades as a moderator and mediator of this association. The sample (N=1364) was drawn from the NICHD Study of Early Child Care and Youth Development. Results from structural equation models indicated that teacher-child conflict in early elementary grades mediated links between children's temperament and later peer interactions. Findings underscore the importance of considering children's temperament traits and teacher-child relationship quality when examining the mechanisms of the development of peer interactions. © 2013.

Challenges facing the treatment of type 2 diabetes necessitate the search for agents which act via alternative pathways to provide better therapeutic outcomes. Recently, an increasing body of evidence implicates the activation of oestrogen receptors (ERα and ERβ) in the development and treatment of underlying conditions in type 2 diabetes. This article summarizes available evidence for the involvement of oestrogen receptors in insulin secretion, insulin resistance as well as glucose uptake and highlights the potential of ERβ as a therapeutic target. Recent studies indicate an association between the activation of each of the isoforms of ER and recent findings indicate that ERβ show promise as a potential target for antidiabetic drugs. In vitro and in vivo studies in receptor knock out mice indicate beneficial actions of selective agonists of ERβ receptor and underscore its therapeutic potential. Studies are needed to further elucidate the exact mechanism underlying the role of ERβ activation as a therapeutic approach in the management of type 2 diabetes.

Public opinion surrounding the recreational use and therapeutic potential of cannabis is shifting. This review describes new work examining the behavioural and neural effects of cannabis and the endocannabinoid system, highlighting key regions within corticolimbic brain circuits. First, we consider the role of human genetic factors and cannabis strain chemotypic differences in contributing to interindividual variation in the response to cannabinoids, such as THC, and review studies demonstrating that THC-induced impairments in decision-making processes are mediated by actions at prefrontal CB 1 receptors. We further describe evidence that signalling through prefrontal or ventral hippocampal CB 1 receptors modulates mesolimbic dopamine activity, aberrations of which may contribute to emotional processing deficits in schizophrenia. Lastly, we review studies suggesting that endocannabinoid tone in the amygdala is a critical regulator of anxiety, and report new data showing that FAAH activity is integral to this response. Together, these findings underscore the importance of cannabinoid signalling in the regulation of cognitive and affective behaviours, and encourage further research given their social, political, and therapeutic implications.

Children with 22q11.2 deletion syndrome (22q11DS), a copy-number variation (CNV) genetic disorder, demonstrate a great deal of variability in IQ scores and are at particular risk for cognitive difficulties, with up to 45% experiencing intellectual disability. This study explored the IQ relationship between individuals with 22q11DS, their parents and their siblings. Participants included individuals with 22q11DS, unaffected siblings and community controls, who participated in a longitudinal study of 22q11DS. Significant associations between proband and relative (parent, sibling) IQ scores were found. Results suggest that the cognitive functioning of first-degree relatives could be a useful marker of general genetic background and/or environmental effects, and can explain some of the large phenotypic variability in 22q11DS. These findings underscore the importance of including siblings and parents in studies of 22q11DS whenever possible. Copyright © 2014 Elsevier Ltd. All rights reserved.

Most theoretical treatments of intimate partner violence (IPV) focus on individual-level processes. Some researchers have attempted to situate IPV within the larger neighborhood context, but few studies have sought to link structural- and individual-level factors. The current analyses fill a research gap by examining the role of anger and depression in the association between neighborhood disadvantage and IPV. Using data from the Toledo Adolescent Relationships Study (TARS) and the 2000 Census, this study focuses on structural indicators of disadvantage as well as subjective disorder, and highlights the complex associations between neighborhood conditions, emotional distress, and IPV. Findings indicate that anger and depressive symptoms partially explain the association between neighborhood disadvantage and IPV. Additionally, the associations between disadvantage, disorder, and IPV depend on respondent’s level of anger. Results underscore the need to further consider the role of neighborhood factors (both objective and subjective) in relation to IPV, and also suggest the utility of introducing individual-level emotional measures to assess the circumstances under which neighborhoods matter most.

This study aimed to extricate the influence of rational (e.g., 'I think …') and intuitive (e.g., 'I feel …') probability beliefs in the behavioural decision-making process regarding skin cancer prevention practices. Structural equation modelling was used in two longitudinal surveys (sun protection during winter sports [N = 491]; sun protection during summer [N = 277]) to examine direct and indirect behavioural effects of affective and cognitive likelihood (i.e. unmediated or mediated by intention), controlled for attitude, social influence and self-efficacy. Affective likelihood was directly related to sun protection in both studies, whereas no direct effects were found for cognitive likelihood. After accounting for past sun protective behaviour, affective likelihood was only directly related to sun protection in Study 1. No support was found for the indirect effects of affective and cognitive likelihood through intention. The findings underscore the importance of feelings of (cancer) risk in the decision-making process and should be acknowledged by health behaviour theories and risk communication practices. Suggestions for future research are discussed.

A child's age in comparison to the age of her or his classmates (relative age) has been found to be an influential factor on academic achievement, particularly but not exclusively at the beginning of formal schooling. However, few studies have focused on the generalizability of relative age effects. To close this gap, the present study analyzes the generalizability across students with and without immigrant backgrounds, across three student cohorts that entered school under a changing law of school enrollment, and across classes. To this end, we capitalized on representative large-scale data sets from three student cohorts attending public schools in Berlin, the capital of Germany. We analyzed the data using a multilevel framework. Our results for the overall student sample indicate relative age effects for reading and mathematics in favor of the relatively older students in Grade 2 that become somewhat smaller in size in Grade 3. By Grade 8, relative age effects had vanished in reading and had even reversed in favor of the relatively young in mathematics. Furthermore, relative age effects were not found to be systematically different among students with and without immigrant backgrounds, student cohorts, or across classes. Taken together, these results empirically underscore the broad generalizability of the findings as found for the overall student population and replicate the pattern of findings on relative effects as identified by the majority of previous studies.

'That would have been beneficial': LGBTQ education for home-care service providers.
Daley, Andrea; MacDonnell, Judith A
2015-05-01
This paper reports qualitative findings from a pilot study that explored the lesbian, gay, bisexual, transgender and queer (LGBTQ) education needs of home-care service providers working in one large, urban Canadian city. The pilot study builds upon research that has documented barriers to health services for diversely situated LGBTQ people, which function to limit access to good-quality healthcare. LGBTQ activists, organisations and allies have underscored the need for health provider education related to the unique health and service experiences of sexual and gender minority communities. However, the home-care sector is generally overlooked in this important body of research literature. We used purposeful convenience sampling to conduct four focus groups and two individual interviews with a total of 15 professionally diverse home-care service providers. Data collection was carried out from January 2011 to July 2012 and data were analysed using grounded theory methods towards the identification of the overarching theme, 'provider education' and it had two sub-themes: (i) experiences of LGBTQ education; and (ii) recommendations for LGBTQ education. The study findings raise important questions about limited and uneven access to adequate LGBTQ education for home-care service providers, suggest important policy implications for the education and health sectors, and point to the need for anti-oppression principles in the development of education initiatives. © 2014 John Wiley & Sons Ltd.

Birth weight is associated with later-life cardiovascular risk. A new study by Romundstad et al. (Am J Epidemiol 2007;166:1359-1364) challenges us to consider influences on birth weight with respect to timing and type. Timing of effects on birth weight, according to the "fetal origins hypothesis," is in utero. Alternatively, familial aggregation--genetics or shared environment--may explain birth weight and suggests prepregnancy influences. The Romundstad et al. findings support familial effects: maternal metabolic factors predicted birth weight for gestational age. However, because maternal physiology sets the fetal environment, these data do not necessarily counter the fetal origins hypothesis. Types of maternal metabolic influences demonstrated by Romundstad et al. include elevations in blood pressure being associated with lower birth weight for gestational age, whereas unfavorable glucose and lipid levels were associated with higher birth weight. These findings are consistent with the authors prior hypothesis that vascular dysfunction and metabolic profile (glucose and lipids) have divergent effects during pregnancy. Moreover, these new data underscore that both extremes of birth weight may be related to cardiovascular risk. Few data sets contain prepregnancy, pregnancy, and childhood information. Without all such time points, life course effects will remain only partially understood. It is hoped that studies such as the forthcoming National Children's Study will generate critical understanding of this issue.

This article considers a eudaimonic approach to psychological well-being built on the integration of developmental, existential and humanistic formulations as well as distant writings of Aristotle. Eudaimonia emphasizes meaning-making, self realization and growth, quality connections to others, self-knowledge, managing life, and marching to one's own drummer. These qualities may be of particular importance in the confrontation with significant life challenges. Prior formulations of resilience are reviewed to underscore the unique features of a eudaimonic approach. Empirical findings on meaning making and self realization are then reviewed to document the capacity of some to maintain high well-being in the face of socioeconomic inequality, the challenges of aging, and in dealing with specific challenges (child abuse, cancer, loss of spouse). Moreover, those who sustain or deepen their well-being as they deal with adversity, show better health profiles, thereby underscoring broader benefits of eudaimonia. How meaning is made and personal capacities realized in the confrontation with challenge is revealed by narrative accounts. Thus, the latter half of the article illustrates human resilience in action via the personal stories of three individuals (Mark Mathabane, Ben Mattlin, Victor Frankl) who endured unimaginable hardship, but prevailed and grew in the face of it. The essential roles of strong social ties and the capacity to derive meaning and realize personal growth in grappling with adversity are unmistakable in all three cases. PMID:25435804

Using multilevel modeling, we separately examined the relations between mothers' and fathers' parenting practices and children's prosocial behavior, as well as the moderating roles of child sex, age, and ethnicity. Participants included a diverse community sample of 129 cohabiting couples with a child aged 6-17. Results indicated that paternal positivity and corporal punishment were significantly related to girls', but not boys', prosocial behavior, and paternal involvement was related to prosocial behavior in school-aged children but not adolescents. Greater levels of positivity in both parents were related to more prosocial behavior in Caucasian children and less in African American children. Overall, the findings suggest that fathers' parenting is important and may differentially influence children of different sexes and ages, underscoring the importance of examining both mothers' and fathers' parenting in relation to child outcomes and with diverse samples. Findings also highlight the need for culturally appropriate measures of parenting.
Motherhood and the Wages of Women in Professional Occupations.
Buchmann, Claudia; McDaniel, Anne
2016-08-01
It is well established that mothers are paid less than childless women and that fathers tend to earn higher wages relative to childless men, but we do not know whether these findings apply to workers in all occupations. Using IPUMS and ACS data from 1980 and 2010, we examine the family wage gap for highly educated professionals, the most advantaged sector of the occupational distribution. Results indicate that the size of the negative wage differential for motherhood has declined over time in all professions. Moreover, in the traditionally male-dominated professions of STEM, medicine, and law, women with children experience a positive wage differential, whereas their counterparts in female-dominated professions continue to experience a negative one. The positive differential for fatherhood has remained stable over time. These findings underscore the growing heterogeneity of women's experiences in combining work and family and raise important questions for further research.

The authors investigated the moderating role of father's education on the associations between perceived paternal parenting styles and locus of control among 382 Malaysian adolescents with an average age of 14.27. Data were collected by means of adolescents' self-report using standardized instruments (i.e., parental authority questionnaire and Nowicki-Strickland Internal-External Control Scale for Children). Results revealed that there were significant negative relationships between fathers' authoritative parenting style (r = -.243, p < .001) and authoritarian parenting style (r = -.130, p < .01) with adolescents' internal locus of control. Furthermore, the findings indicated that father's high level of education moderated the relationship between perceived paternal authoritarian parenting and locus of control (b = -0.147, p < .001). The findings underscore the need to include the role of parents' education when assessing the links between parenting styles and adolescents' locus of control.
A paradigm for the study of paranoia in the general population: the Prisoner's Dilemma Game.

A growing body of research shows that paranoia is common in the general population. We report three studies that examined the Prisoner's Dilemma Game (PDG) as a paradigm for evaluation of non-clinical paranoia. The PDG captures three key qualities that are at the heart of paranoia--it is interpersonal, it concerns threat, and it concerns the perception of others' intentions towards the self. Study 1 (n=175) found that state paranoia was positively associated with selection of the competitive PDG choice. Study 2 (n=111) found that this association was significant only when participants believed they were playing the PDG against another person, and not when playing against a computer. This finding underscores the interpersonal nature of paranoia and the concomitant necessity of studying paranoia in interpersonal context. In Study 3 (n=152), we assessed both trait and state paranoia, and differentiated between distrust- and greed-based competition. Both trait and state paranoia were positively associated with distrust-based competition (but not with greed-based competition). Crucially, we found that the association between trait paranoia and distrust-based competition was fully mediated by state paranoia. The PDG is a promising paradigm for the study of non-clinical paranoia.

Stressful life events are an established trigger for depression and may contribute to the heterogeneity within genome-wide association analyses. With depression cases showing an excess of exposure to stressful events compared to controls, there is difficulty in distinguishing between "true" cases and a "normal" response to a stressful environment. This potential contamination of cases, and that from genetically at risk controls that have not yet experienced environmental triggers for onset, may reduce the power of studies to detect causal variants. In the RADIANT sample of 3,690 European individuals, we used propensity score matching to pair cases and controls on exposure to stressful life events. In 805 case-control pairs matched on stressful life event, we tested the influence of 457,670 common genetic variants on the propensity to depression under comparable level of adversity with a sign test. While this analysis produced no significant findings after genome-wide correction for multiple testing, we outline a novel methodology and perspective for providing environmental context in genetic studies. We recommend contextualizing depression by incorporating environmental exposure into genome-wide analyses as a complementary approach to testing gene-environment interactions. Possible explanations for negative findings include a lack of statistical power due to small sample size and conditional effects, resulting from the low rate of adequate matching. Our findings underscore the importance of collecting information on environmental risk factors in studies of depression and other complex phenotypes, so that sufficient sample sizes are available to investigate their effect in genome-wide association analysis.

Energy-resolved competitive collision-induced dissociation methods are used to measure the gas-phase acidities of a series of alcohols (methanol, ethanol, 2-propanol, and 2-methyl-2-propanol). The competitive dissociation reactions of fluoride-alcohol, [F{sup {minus}}{center{underscore}dot}HOR], alkoxide-water, [RO{sup {minus}}{center{underscore}dot}HOH], and alkoxide-methanol [RO{+-}{center{underscore}dot}HOCH{sub 3}] proton-bound complexes are studied using a guided ion beam tandem mass spectrometer. The reaction cross sections and product branching fractions to the two proton transfer channels are measured as a function of collision energy. The enthalpy difference between the two product channels is found by modeling the reaction cross sections near threshold using RRKM theory to account for the energy-dependent product branching ratiomore » and kinetic shift. From the enthalpy difference, the alcohol gas-phase acidities are determined relative to the well-known values of HF and H{sub 2}O. The measured gas-phase acidities are {Delta}{sub acid}H{sub 298}(CH{sub 3}OH) = 1599 {+-} 3 kJ/mol, {Delta}{sub acid}H{sub 298}(CH{sub 3}CH{sub 2}OH) = 1586 {+-} 5 kJ/mol, {Delta}{sub acid}H{sub 298}((CH{sub 3}){sub 2}CHOH) = 1576 {+-} 4 kJ/mol, and {Delta}{sub acid}H{sub 298}((CH{sub 3}){sub 3}COH) = 1573 {+-} 3 kJ/mol.« less
Child Adjustment and Parent Functioning: Considering the Role of Child Driven Effects
Yan, Ni; Ansari, Arya
2016-01-01
Based on 13,694 mother-child dyads from the Early Childhood Longitudinal Kindergarten Cohort (ECLS-K), this study examined the bidirectional relations between parental and child functioning from kindergarten through third grade. Results from the cross-lagged models demonstrated that child-driven effects co-occurred with parental effects and these effects were comparable in size. At the same time, however, results from the latent profile analysis revealed idiosyncratic patterns of parent and child functioning. Compared with children in the least optimal functioning profiles, those in the average and above average profiles elicited greater improvements in parents’ functioning over time. Although children characterized by poor academic performance at kindergarten appeared to precede parents characterized by harsh parenting at third grade, there was a threshold in the evolving strength of the overall child-driven effects. Taken together, the results from this study underscore the importance of considering reciprocal processes in the parent-child dynamic while also underscoring individual differences in these processes across the early to middle childhood years.

The National Institute of Drug Abuse's National Drug Abuse Treatment Clinical Trials Network (CTN) was established to foster translation of research into practice in substance abuse treatment settings. The CTN provides a unique opportunity to examine in multi-site, translational clinical trials, the outcomes of treatment interventions targeting vulnerable subgroups of women; the comparative effectiveness of gender-specific protocols to reduce risk behaviors; and gender differences in clinical outcomes. To review gender-related findings from published CTN clinical trials and related studies from January 2000 to March 2010. CTN studies were selected for review if they focused on treatment outcomes or services for special populations of women with substance use disorders (SUDs) including those with trauma histories, pregnancy, co-occurring eating and other psychiatric disorders, and HIV risk behaviors; or implemented gender-specific protocols. The CTN has randomized 11,500 participants (41% women) across 200 clinics in 24 randomized controlled trials in community settings, of which 4 have been gender-specific. This article summarizes gender-related findings from CTN clinical trials and related studies, focusing on trauma histories, pregnancy, co-occurring eating and other psychiatric disorders, and HIV risk behaviors. These published studies have expanded the evidence base regarding interventions for vulnerable groups of women with SUDs as well as gender-specific interventions to reduce HIV risk behaviors in substance-using men and women. The results also underscore the complexity of accounting for gender in the design of clinical trials and analysis of results. To fully understand the relevance of gender-specific moderators and mediators of outcome, it is essential that future translational studies adopt more sophisticated approaches to understanding and measuring gender-relevant factors and plan sample sizes that are adequate to support more nuanced analytic methods.
Tragedy into policy: a quantitative study of nurses' attitudes toward patient advocacy activities.
Black, Lisa M
2011-06-01
In 2007 and 2008, 115 patients were found to be either certainly or presumptively infected with the hepatitis C virus through the reuse of contaminated medication vials at two southern Nevada endoscopy clinics. A subsequent joint investigation by federal and state agencies found multiple breaches of infection control protocols. There was also strong anecdotal evidence that among clinic staff, unsafe patient care conditions often went unreported because of a general fear of retaliation. At the request of the Nevada legislature's Legislative Committee on Health Care, a study was conducted to examine Nevada RNs' experiences with workplace attitudes toward patient advocacy activities. This article presents the study findings and reviews how one public health tragedy led to the creation of effective health care policy. A study questionnaire was developed and tested for reliability and validity. Questionnaires were then sent to an initial sample of 1,725 Nevada RNs, representing 10% of all RNs in the Nevada State Board of Nursing database with active licenses and current Nevada addresses. The response rate was modest at 33% (564 respondents). Of those who responded, 34% indicated that they'd been aware of a patient care condition that could have caused harm to a patient, yet hadn't reported it. The most common reasons given for nonreporting included fears of workplace retaliation (44%) and a belief that nothing would come of reports that were made (38%). The study findings underscore the need for a shift in organizational culture toward one that encourages clear and open communication when patient safety may be in jeopardy. These findings were ultimately used to support the passage of whistleblower protection legislation in Nevada. Las Vegas hepatitis C outbreak, patient advocacy, whistleblower.
Clinical decision-making among new graduate nurses attending residency programs in Saudi Arabia.

This study examined the impact of residency programs on clinical decision-making of new Saudi graduate nurses who completed a residency program compared to new Saudi graduate nurses who did not participate in residency programs. This descriptive study employed a convenience sample (N=98) of new graduate nurses from three hospitals in Saudi Arabia. A self-administered questionnaire was used to collect data. Clinical decision-making skills were measured using the Clinical Decision Making in Nursing Scale. Descriptive statistics, independent t-tests, and multiple linear regression analysis were utilized to examine the effect of residency programs on new graduate nurses' clinical decision-making skills. On average, resident nurses had significantly higher levels of clinical decision-making skills than non-residents (t=23.25, p=0.000). Enrollment in a residency program explained 86.9% of the variance in total clinical decision making controlling for age and overall grade point average. The findings of this study support evidence in the nursing literature conducted primarily in the US and Europe that residency programs have a positive influence on new graduate nurses' clinical decision-making skills. This is the first study to examine the impact of residency programs on clinical decision-making among new Saudi graduate nurses who completed a residency program. The findings of this study underscore the need for the development and implementation of residency programs for all new nurses. Copyright © 2015 Elsevier Inc. All rights reserved.

College women frequently report having experienced sexual victimization (SV) in their lifetime, including child sexual abuse and adolescent/adult sexual assault. Although the harmful mental health sequelae of SV have been extensively studied, recent research suggests that SV is also a risk factor for poorer college academic performance. The current studies examined whether exposure to SV uniquely predicted poorer college academic performance, even beyond contributions from three well-established predictors of academic performance: high school rank, composite standardized test scores (i.e., American College Testing [ACT]), and conscientiousness. Study 1 analyzed longitudinal data from a sample of female college students (N = 192) who were assessed at the beginning and end of one semester. SV predicted poorer cumulative end-of-semester grade point average (GPA) while controlling for well-established predictors of academic performance. Study 2 replicated these findings in a second longitudinal study of female college students (N = 390) and extended the analyses to include follow-up data on the freshmen and sophomore students (n = 206) 4 years later. SV predicted students' GPA in their final term at the university above the contributions of well-established academic predictors, and it was the only factor related to leaving college. These findings highlight the importance of expanding the scope of outcomes of SV to include academic performance, and they underscore the need to assess SV and other adverse experiences on college campuses to target students who may be at risk of poor performance or leaving college.

Epilepsy is a chronic brain syndrome characterized by recurrent seizures resulting from excessive neuronal discharges. Despite the development of various new antiepileptic drugs, many patients are refractory to treatment and report side effects. Non-invasive methods of brain stimulation, such as transcranial direct current stimulation (tDCS), have been tested as alternative approaches to directly modulate the excitability of epileptogenic neural circuits. Although some pilot and initial clinical studies have shown positive results, there is still uncertainty regarding the next steps of investigation in this field. Therefore, we reviewed preclinical and clinical studies using the following framework: (1) preclinical studies that have been successfully translated to clinical studies, (2) preclinical studies that have failed to be translated to clinical studies, and (3) clinical findings that were not previously tested in preclinical studies. We searched PubMed, Web of Science, Embase, and SciELO (2002–2017) using the keywords “tDCS,” “epilepsy,” “clinical trials,” and “animal models.” Our initial search resulted in 64 articles. After applying inclusion and exclusion criteria, we screened 17 full-text articles to extract findings about the efficacy of tDCS, with respect to the therapeutic framework used and the resulting reduction in seizures and epileptiform patterns. We found that few preclinical findings have been translated into clinical research (number of sessions and effects on seizure frequency) and that most findings have not been tested clinically (effects of tDCS on status epilepticus and absence epilepsy, neuroprotective effects in the hippocampus, and combined use with specific medications). Finally, considering that clinical studies on tDCS have been conducted for several epileptic syndromes, most were not previously tested in preclinical studies (Rasmussen's encephalitis, drug resistant epilepsy, and hippocampal sclerosis-induced epilepsy). Overall, most studies report positive findings. However, it is important to underscore that a successful preclinical study may not indicate success in a clinical study, considering the differences highlighted herein. Although most studies report significant findings, there are still important insights from preclinical work that must be tested clinically. Understanding these factors may improve the evidence for the potential use of this technique as a clinical tool in the treatment of epilepsy. PMID:29623027

Designing heavy metal oxide glasses with threshold properties from network rigidity
NASA Astrophysics Data System (ADS)
Chakraborty, Shibalik; Boolchand, P.; Malki, M.; Micoulaut, M.
2014-01-01
Here, we show that a new class of glasses composed of heavy metal oxides involving transition metals (V2O5-TeO2) can surprisingly be designed from very basic tools using topology and rigidity of their underlying molecular networks. When investigated as a function of composition, such glasses display abrupt changes in network packing and enthalpy of relaxation at Tg, underscoring presence of flexible to rigid elastic phase transitions. We find that these elastic phases are fully consistent with polaronic nature of electronic conductivity at high V2O5 content. Such observations have new implications for designing electronic glasses which differ from the traditional amorphous electrolytes having only mobile ions as charge carriers.
Contextual priming: Where people vote affects how they vote
Berger, Jonah; Meredith, Marc; Wheeler, S. Christian
2008-01-01
American voters are assigned to vote at a particular polling location (e.g., a church, school, etc.). We show these assigned polling locations can influence how people vote. Analysis of a recent general election demonstrates that people who were assigned to vote in schools were more likely to support a school funding initiative. This effect persisted even when controlling for voters' political views, demographics, and unobservable characteristics of individuals living near schools. A follow-up experiment using random assignment suggests that priming underlies these effects, and that they can occur outside of conscious awareness. These findings underscore the subtle power of situational context to shape important real-world decisions. PMID:18574152

Objectives We estimated the prevalence of recess-based moderate and vigorous physical activity (MVPA) and vigorous physical activity (VPA) among third grade students attending low-income, urban schools in Texas. Methods Structured observations (n=77 class and 616 student observations) using SOFIT were conducted over three-months in 8 elementary schools with majority Hispanic students. Results Students engaged in 66.4% and 19.2% of their ~20 minute recess time in MVPA and VPA, respectively. Boys engaged in more MVPA and VPA (P<.007). Contextual differences in activity (setting and activity type) were identified. Conclusions Findings underscore the importance of scheduled recess time for children’s physical activity. PMID:23985178
Complex role of HIF in cancer: the known, the unknown, and the unexpected
Tiburcio, Patricia Denise; Choi, Hyunsung; Huang, L Eric
2014-01-01
Tumor hypoxia has long been recognized as a driving force of malignant progression and therapeutic resistance. The discovery of hypoxia-inducible transcription factors (HIFs) has greatly advanced our understanding of how cancer cells cope with hypoxic stress by maintaining bioenergetics through the stimulation of glycolysis. Until recently, however, it remained perplexing why proliferative cancer cells opt for aerobic glycolysis, an energy-inefficient process of glucose metabolism. Furthermore, the role of HIF in cancer has also become complex. In this review, we highlight recent groundbreaking findings in cancer metabolism, put forward plausible explanations to the complex role of HIF, and underscore remaining issues in cancer biology.

Soil transmitted nematodes, including Strongyloides, cause one of the most prevalent Neglected Tropical Diseases. Here we compare the genomes of four Strongyloides spp., including the human pathogen S. stercoralis, and their close relatives that are facultatively parasitic (Parastrongyloides trichosuri) and free-living (Rhabditophanes sp). A significant paralogous expansion of key gene families – astacin-like and SCP/TAPS coding gene families – is associated with the evolution of parasitism in this clade. Exploiting the unique Strongyloides life cycle we compare the transcriptome of its parasitic and free-living stages and find that these same genes are upregulated in the parasitic stages, underscoring their role in nematode parasitism.

This paper presents empirical research analyzing the relationship between work–family climate (operationalized in terms of three work–family climate sub-scales), organizational leadership (i.e., senior manager) characteristics, organizational commitment and turnover intent among 526 employees from 37 different hotels across the US. Using multilevel modeling, we found significant associations between work–family climate, and both organizational commitment and turnover intent, both within and between hotels. Findings underscored the importance of managerial support for employee work–family balance, the relevance of senior managers’ own work–family circumstances in relation to employees’ work outcomes, and the existence of possible contagion effects of leaders in relation to work–family climate.

Fluorescent in situ hybridization (FISH) is a molecular cytogenetic technique that is playing an increasingly important role for augmenting the findings of conventional cytogenetics. Here we present the case history of a patient with the clinical diagnosis of secondary acute myelogenous leukemia whose bone marrow cells were found to be hyperdiploid with an extra C group chromosome in a less than optimal preparation. By using FISH the extra chromosome was unequivocally determined to be a chromosome 9. The detection of trisomy 9 in this patient underscores the utility of FISH as an adjunct to GTG banding in the routine diagnosis and management of leukemic patients.
STRUCTURAL INEQUALITY AND SOCIAL SUPPORT FOR WOMEN PRISONERS RELEASED TO RURAL COMMUNITIES
Nicdao, Ethel G.; Trott, Elise M.; Kellett, Nicole C.
2016-01-01
Incarceration and community reentry for rural women reflect gendered processes. We draw upon in-depth semi-structured interviews and focus groups to examine the return of women prisoners to underserved rural communities, while attending to the perspectives of their closest social supporters. Our findings underscore the complexity of the reentry process for rural women and its particular impact on their families. We challenge dominant discourses of personal responsibility that detract from the structura violence and injustice shaping reentry experiences for women and their social supporters. We also consider the policy implications of discharge and reentry planning for rural women and their families, as well as strategies to reduce recidivism. PMID:27274615

Though most personality researchers now recognize that ratings of the Big Five are not orthogonal, the field has been divided about whether these trait intercorrelations are substantive (i.e., driven by higher order factors) or artifactual (i.e., driven by correlated measurement error). We used a meta-analytic multitrait-multirater study to estimate trait correlations after common method variance was controlled. Our results indicated that common method variance substantially inflates trait correlations, and, once controlled, correlations among the Big Five became relatively modest. We then evaluated whether two different theories of higher order factors could account for the pattern of Big Five trait correlations. Our results did not support Rushton and colleagues' (Rushton & Irwing, 2008; Rushton et al., 2009) proposed general factor of personality, but Digman's (1997) α and β metatraits (relabeled by DeYoung, Peterson, and Higgins (2002) as Stability and Plasticity, respectively) produced viable fit. However, our models showed considerable overlap between Stability and Emotional Stability and between Plasticity and Extraversion, raising the question of whether these metatraits are redundant with their dominant Big Five traits. This pattern of findings was robust when we included only studies whose observers were intimately acquainted with targets. Our results underscore the importance of using a multirater approach to studying personality and the need to separate the causes and outcomes of higher order metatraits from those of the Big Five. We discussed the implications of these findings for the array of research fields in which personality is studied.
Common mental disorders in mothers vs. infant and obstetric outcomes: a review.
Borba, Paula; Zambaldi, Carla Fonseca; Cantilino, Amaury; Sougey, Everton Botelho
2012-01-01
Pregnancy has been shown to increase women's vulnerability to mental disorders. Common mental disorders (CMDs) have been studied both in the general population and in pregnant vs. non-pregnant women. During pregnancy, CMDs have been considered a potential predictor of obstetric and infant outcomes. A search was conducted on the PubMed/MEDLINE, LILACS, and SciELO databases to find relevant articles written in English, Spanish, and Portuguese. No limit was established for year of publication, but only studies involving human beings were included. A total of 25 articles were selected. There was a consensus among studies that the mean prevalence of CMD during pregnancy is 20%. There was also agreement that the occurrence of CMDs during pregnancy is a predictor of postpartum depression and anxiety disorders and that the disorder remains underdiagnosed and undertreated. As for the positive association between CMDs and obstetric and infant complications, results are still conflicting. In lower-income countries, frequently there is an association between CMD and perinatal changes. It is argued that some confounding factors, such as sociodemographic and cultural differences, health and maternal conditions, and type of instruments used, probably contribute to this lack of consensus. We believe that the conflicting results found in the literature are caused by differences in methodology and sociodemographic factors that influence the development of CMDs. Despite these differences, our findings underscore the need for depression and anxiety disorders during pregnancy to be studied and better identified by all professionals who provide antenatal care.
Child first language and adult second language are both tied to general-purpose learning systems.
Hamrick, Phillip; Lum, Jarrad A G; Ullman, Michael T
2018-02-13
Do the mechanisms underlying language in fact serve general-purpose functions that preexist this uniquely human capacity? To address this contentious and empirically challenging issue, we systematically tested the predictions of a well-studied neurocognitive theory of language motivated by evolutionary principles. Multiple metaanalyses were performed to examine predicted links between language and two general-purpose learning systems, declarative and procedural memory. The results tied lexical abilities to learning only in declarative memory, while grammar was linked to learning in both systems in both child first language and adult second language, in specific ways. In second language learners, grammar was associated with only declarative memory at lower language experience, but with only procedural memory at higher experience. The findings yielded large effect sizes and held consistently across languages, language families, linguistic structures, and tasks, underscoring their reliability and validity. The results, which met the predicted pattern, provide comprehensive evidence that language is tied to general-purpose systems both in children acquiring their native language and adults learning an additional language. Crucially, if language learning relies on these systems, then our extensive knowledge of the systems from animal and human studies may also apply to this domain, leading to predictions that might be unwarranted in the more circumscribed study of language. Thus, by demonstrating a role for these systems in language, the findings simultaneously lay a foundation for potentially important advances in the study of this critical domain.

Hypertension has adverse effects on cognition, can alter cerebral vasculature integrity, and is associated with the pathogenesis of dementia. Using meta-analysis, we correlated blood pressure to multiple cognitive domains among older adults free of clinical stroke and dementia. We identified 230 studies indexed in PubMed and PsycINFO relating blood pressure and cognition. After applying exclusion criteria, we selected n = 12 articles with n = 4,076 participants (age range 43–91 years). Meta-analysis yielded an association between blood pressure and episodic memory (r = −.18, p < .001) and between blood pressure and global cognition (r = −.07, p < .001). When limiting analyses to studies adjusting for vascular covariates (n = 8, n = 2,141), blood pressure was modestly related to global cognition (r = −.11, p < .001), attention (r = .14, p = .002), and episodic memory (r = −.20, p < .001) with a trend for language (r = −.22, p = .07). Findings underscore the need to manage blood pressure as a key prevention method in minimizing abnormal cognitive aging prior to the onset of clinical dementia. PMID:23838685
Depression, insight, and personality changes in Alzheimer's disease and vascular dementia.
Verhey, F R; Ponds, R W; Rozendaal, N; Jolles, J
1995-01-01
Although it is generally believed that depression, retained insight, and preserved personality occur more frequently in vascular dementia than in Alzheimer's disease, there is little empiric evidence for this presumption. Most studies on this subject have been carried out with severely demented inpatients, and confounding factors such as age, sex, and severity of dementia have not been sufficiently taken into account. We compared 48 patients with relatively mild vascular dementia with 48 patients with Alzheimer's disease, matched for age, sex, and stage of dementia, to investigate if depression, lack of insight, and personality changes were related to the cause of dementia. The two groups did not differ regarding the incidence of major depression, the mean depression score, the awareness score, or the sum of scores on the items of the Blessed Dementia Scale concerning personality changes. We conclude that depression, lack of insight, and personality changes do not favor an etiology of vascular dementia over that of Alzheimer's disease. The present findings underscore the notion that the severity of the dementia should be considered in studies on the differences between vascular dementia and Alzheimer's disease.
Islet Long Noncoding RNAs: A Playbook for Discovery and Characterization.
Singer, Ruth A; Sussel, Lori
2018-06-24
Diabetes is a complex group of metabolic disorders that can be accompanied by several comorbidities, including increased risk of early death. Decades of diabetes research have elucidated many genetic drivers of normal islet function and dysfunction; however, a lack of suitable treatment options suggests our knowledge about the disease remains incomplete. The establishment of long noncoding RNAs (lncRNAs), once dismissed as "junk" DNA, as essential gene regulators in many biological processes has redefined the central role for RNA in cells. Studies showing that misregulation of lncRNAs can lead to disease have contributed to the emergence of lncRNAs as attractive candidates for drug targeting. These findings underscore the need to reexamine islet biology in the context of a regulatory role for RNA. This review will 1 ) highlight what is known about lncRNAs in the context of diabetes, 2 ) summarize the strategies used in lncRNA discovery pipelines, and 3 ) discuss future directions and the potential impact of studying the role of lncRNAs in diabetes. © 2018 by the American Diabetes Association.

In this study, we demonstrate that changes of the North Atlantic subtropical high and its regional rainfall pattern during mid-Holocene precessional changes and idealized 4xCO 2 increase can both be understood as a remote response to increased land heating near North Africa. Despite different sources and patterns of radiative forcing (increase in CO 2 concentration versus changes in orbital parameters), we find that the pattern of energy, circulation, and rainfall responses in the Northern Hemisphere summer subtropics are remarkably similar in the two forcing scenarios because both are dominated by the same land-sea heating contrast in response to the forcing.more » An increase in energy input over arid land drives a westward displacement of the coupled North Atlantic subtropical high-monsoon circulation, consistent with increased precipitation in the Afro-Asia region and decreased precipitation in the America-Atlantic region. This study underscores the importance of land heating in dictating remote drying through zonal shifts of the subtropical circulation.« less
Life Cycle Water Consumption for Shale Gas and Conventional Natural Gas

2013-10-15
Shale gas production represents a large potential source of natural gas for the nation. The scale and rapid growth in shale gas development underscore the need to better understand its environmental implications, including water consumption. This study estimates the water consumed over the life cycle of conventional and shale gas production, accounting for the different stages of production and for flowback water reuse (in the case of shale gas). This study finds that shale gas consumes more water over its life cycle (13–37 L/GJ) than conventional natural gas consumes (9.3–9.6 L/GJ). However, when used as a transportation fuel, shale gasmore » consumes significantly less water than other transportation fuels. When used for electricity generation, the combustion of shale gas adds incrementally to the overall water consumption compared to conventional natural gas. The impact of fuel production, however, is small relative to that of power plant operations. The type of power plant where the natural gas is utilized is far more important than the source of the natural gas.« less

The phenomenon of women's underrepresentation in engineering is well known. However, the slow progress in achieving better gender equality here compared with other domains has accentuated the 'numbers' issue, while the quality aspects have been largely ignored. This study aims to shed light on both these aspects via the lens of mentors, who are at the coalface of guiding female engineers through their education and subsequent careers. Based on data collected from 25 mentors (8 men and 17 women from 8 countries), the paper explores their experiences of being mentors, as well as their views on recommended actions for nurturing female engineers. The findings reveal that the primary motivation for becoming a mentor was personal for men and women. Many mentors from countries with relatively lower female labour participation rates perceive their roles as guarantors of their mentees' successful future career paths, and a similar trend can be found in mentors in academia. The study underscores the need for invigorating mentors' roles in order to secure a more equitable future for engineering education.

Efforts to delineate the basis for variations in protein profiles of different membrane fractions from various bacterial pathogens led to the finding that even the same medium [e.g., Luria Bertani (LB) broth] purchased from different commercial sources generates remarkably dissimilar protein profiles despite similar growth characteristics. Given the pervasive roles small RNAs play in regulating gene expression, we inquired if these source-specific differences due to media arise from disparities in the presence of small RNAs. Indeed, LB media components from two different commercial suppliers contained varying, yet significant, amounts of 10-80 bp small RNAs. Removal of small RNA from LB using RNaseA during media preparation resulted in significant changes in bacterial protein expression profiles. Our studies underscore the fact that seemingly identical growth media can lead to dramatic alterations in protein expression patterns, highlighting the importance of utilizing media free of small RNA during bacteriological studies. Finally, these results raise the intriguing possibility that similar pools of small RNAs in the environment can influence bacterial adaptation.
Handgrip Strength as a Darwinian Fitness Indicator in Men.
Gallup, Andrew C; Fink, Bernhard
2018-01-01
Handgrip strength (HGS) is a robust measure of overall muscular strength and function, and has long been predictive of a multitude of health factors and physical outcomes for both men and women. The fact that HGS represents such a ubiquitous measure of health and vitality may reflect the significance of this trait during human evolution. This trait is also highly sexually dimorphic due to influences of androgenic hormones and fat-free body mass, suggesting that it has been further elaborated through sexual selection. Consistent with this view, research within evolutionary psychology and related fields has documented distinct relationships between HGS and measures of social and sexual behavior, especially in men. Here, we review studies across different societies and cultural contexts showing that male HGS predicts measures of aggression and social dominance, perceived formidability, male-typical body morphology and movement, courtship display, physical attractiveness, and sexual behavior and reproductive fitness. These findings underscore the value of including HGS as an independent measure within studies examining human sexual selection, and corroborate existing research suggesting that specific features of physical strength have and continue to be under positive directional selection in men.
Posttraumatic Stress Disorder and Stressful Life Events Among Rural Women With HIV Disease.
Kemppainen, Jeanne K; MacKain, Sally; Alexander, Melissa; Reid, Paula; Jackson, Morgan Parks
Posttraumatic stress disorder (PTSD) and stressful life events are frequent and distressing problems for women living with HIV (WLWH). Studies have independently focused on the impact of these problems, but little work has examined the relationship between PTSD and stressful life events. Our cross-sectional study examined relationships between PTSD and recent stressful life events in WLWH. A sample of 60 women recruited through HIV community agencies in southeastern North Carolina completed the Stressful Life Events Questionnaire and the PTSD Checklist-Civilian Version (PCL-C). PTSD prevalence was high (43.2%). Two-thirds (66%) reported three or more recent life stressors. Women who experienced a higher number of recent life stressors scored higher on the PCL-C than those with fewer life stressors (p < .001). Recent stressful life events may accelerate PTSD symptoms. Findings underscore the importance of addressing mental health issues in HIV treatment settings. Implications for nursing practice are provided. Copyright © 2016 Association of Nurses in AIDS Care.

Perceived discrimination is a risk factor for mental health problems among sexual minority individuals. An increasing number of research studies have investigated the mechanisms through which stigma-related stressors such as perceived discrimination are linked with adverse mental health outcomes for sexual minority populations. The integrative mediation framework proposed by Hatzenbuehler (2009) underscores the importance of identifying mediators in the association between stigma-related stressors and mental health outcomes. This study tested 3 mediators--expectations of rejection, anger rumination, and self-compassion--in the perceived discrimination-distress link. Moreover, it examined associations among these mediators. A nationwide sample of 265 sexual minorities responded to an online survey. Structural equation modeling results supported the mediator roles of expectations of rejection, anger rumination, and self-compassion. More specifically, perceived discrimination was associated with expectations of rejection, which, in turn, was associated with increased anger rumination and less self-compassion, resulting in greater psychological distress. The findings suggest several avenues for prevention and intervention with sexual minority individuals. (c) 2015 APA, all rights reserved).

This study explored the role of organizational factors in the ability of Veterans Health Administration (VHA) clinics to implement colocated mental health care in primary care settings (PC-MH). The study used data from the VHA Clinical Practice Organizational Survey collected in 2007 from 225 clinic administrators across the United States. Clinic degree of implementation of PC-MH was the dependent variable, whereas independent variables included policies and procedures, organizational context, and leaders' perceptions of barriers to change. Pearson bivariate correlations and multivariable linear regression were used to test hypotheses. Results show that depression care training for primary care providers and clinics' flexibility and participation were both positively correlated with implementation of PC-MH. However, after accounting for other factors, regressions show that only training primary care providers in depression care was marginally associated with degree of implementation of PC-MH (p = 0.051). Given the importance of this topic for implementing integrated care as part of health care reform, these null findings underscore the need to improve theory and testing of more proximal measures of colocation in future work.
Does food marketing need to make us fat? A review and solutions.
Chandon, Pierre; Wansink, Brian
2012-10-01
Food marketing is often singled out as the leading cause of the obesity epidemic. The present review examines current food marketing practices to determine how exactly they may be influencing food intake, and how food marketers could meet their business objectives while helping people eat healthier. Particular attention is paid to the insights provided by recently published studies in the areas of marketing and consumer research, and those insights are integrated with findings from studies in nutrition and related disciplines. The review begins with an examination of the multiple ways in which 1) food pricing strategies and 2) marketing communication (including branding and food claims) bias food consumption. It then describes the effects of newer and less conspicuous marketing actions, focusing on 3) packaging (including the effects of package design and package-based claims) and 4) the eating environment (including the availability, salience, and convenience of food). Throughout, this review underscores the promising opportunities that food manufacturers and retailers have to make profitable "win-win" adjustments to help consumers eat better. © 2012 International Life Sciences Institute.

Workplace bullying is a widespread and challenging problem in healthcare organizations, bearing negative consequences for individuals and organizations. Drawing on the job demands-resources theory, in this study, we examined the relationship between workplace bullying and burnout among healthcare employees, as well as the moderating role of job autonomy and occupational self-efficacy in this relationship. Using a cross-sectional design with anonymous questionnaires, data were collected from two samples of 309 healthcare employees in a mental health facility, and 105 nurses studying for their bachelor degree in health systems administration. The findings indicated that workplace bullying was positively related to burnout dimensions, and that this relationship was moderated by job autonomy and occupational self-efficacy resources. Job autonomy interacted with workplace bullying in predicting emotional exhaustion and depersonalization; the interaction of bullying with occupational self-efficacy significantly predicted depersonalization. These results underscore the importance of control-related resources in mitigating the harmful effects of workplace bullying on employees. Implications for research and managerial practices are discussed. © 2017 John Wiley & Sons Australia, Ltd.

This study explored the role of organizational factors in the ability of Veterans Health Administration (VHA) clinics to implement colocated mental health care in primary care settings (PC-MH). The study used data from the VHA Clinical Practice Organizational Survey collected in 2007 from 225 clinic administrators across the United States. Clinic degree of implementation of PC-MH was the dependent variable, whereas independent variables included policies and procedures, organizational context, and leaders’ perceptions of barriers to change. Pearson bivariate correlations and multivariable linear regression were used to test hypotheses. Results show that depression care training for primary care providers and clinics’ flexibility and participation were both positively correlated with implementation of PC-MH. However, after accounting for other factors, regressions show that only training primary care providers in depression care was marginally associated with degree of implementation of PC-MH (p = 0.051). Given the importance of this topic for implementing integrated care as part of health care reform, these null findings underscore the need to improve theory and testing of more proximal measures of colocation in future work.

Cross-cultural studies of neurodegenerative disorders are especially important when the disease in question is difficult to diagnose, particularly if symptoms of the illness include behavioral disturbances that may be interpreted differently in different cultures. One such disease is frontotemporal lobar degeneration (FTLD), an early-age-of-onset dementia that disproportionately affects social behavior. We report the demographic and neuropsychological characteristics of more than 300 patients diagnosed with FTLD in the United States (US), Greece and Turkey. We find that patients with the frontal variant of FTLD (FTD) are diagnosed at an earlier age and report earlier symptom onset in the US, than in Greece or Turkey. Furthermore, neuropsychological measures indicate that at diagnosis, FTD patients in the US are less impaired than patients in Greece and Turkey. Patients with FTD in Greece and Turkey are diagnosed later in the disease, presumably because their behavioral symptoms are not easily detected by the medical system in these countries. Our study underscores the need to create culturally-appropriate indices of the behavioral symptoms of FTLD, so that patients may be diagnosed and treated at an earlier stage. PMID:18695586
