Wasta (i.e. the distribution of favours among family, friends and tribe; favouritism; nepotism) permeates numerous Middle Eastern cultures, representing a method of strengthening social ties and showing loyalty/generosity, but also representing one of the largest sources of corruption in Middle East. The current study investigated links between wasta and psychological distress in a survey of 1088 educators from Saudi Arabia. Drawing from the self-determination theory (SDT) conceptual framework, Structural Equation Modeling analyses suggested that benefitting from wasta was linked to higher levels of psychological distress and those links were explained in part (i...

BACKGROUND: Studies addressing the organizational contexts of care that may help increase the patients' ability to cope with a disease and to navigate through the health care system are still rare. Especially instruments allowing the assessment of such organizational efforts from the patients' perspective are missing. The aim of our study was to develop a survey instrument assessing organizational health literacy (HL) from the patients' perspective, i. e., health care organizations' responsiveness to patients' individual needs...

The excessive discharge of phosphorus (P) from sewage treatment plants and runoff from agricultural fields is causing a rapid contamination of water resources worldwide. Several materials have been evaluated for the removal of excess P from waste supplies, but designing a cost-effective and environmental friendly substrate is essential for the efficient P removal. In this study, bio-calcite (BC) derived from waste hen eggshell was subjected to thermal treatments (CBC). The BC and CBC further modified via magnesiothermal treatments to produced MBC and MCBC, respectively, and evaluated as a novel green sorbent for P removal from aqueous solutions...

BACKGROUND: Depression is the most common comorbidity in obsessive-compulsive disorder (OCD). However, the mechanisms of depressive comorbidity in OCD are poorly understood. We assessed the directionality and moderators of the OCD-depression association over time in a large, prospective clinical sample of OCD patients. METHODS: Data were drawn from 382 OCD patients participating at the Netherlands Obsessive-Compulsive Disorder Association (NOCDA) study. Cross-lagged, structural equation modeling analyses were used to assess the temporal association between OCD and depressive symptoms...

During adolescence, prefrontal cortex regions, important in cognitive control, undergo maturation to adapt to changing environmental demands. Ways through which social-ecological factors contribute to adolescent neural cognitive control have not been thoroughly examined. We hypothesize that household chaos is a context that may modulate the associations among parental control, adolescent neural cognitive control, and developmental changes in social competence. The sample involved 167 adolescents (ages 13-14 at Time 1, 53% male)...

A great challenge in medicinal chemistry is to develop different methods for structural design based on the pattern of the previously synthesized compounds. In this study two different QSAR methods were established and compared for a series of piperidine acetylcholinesterase inhibitors. In one novel approach, PC-LS-SVM and PLS-LS-SVM was used for modeling 3D interaction descriptors, and in the other method the same nonlinear techniques were used to build QSAR equations based on field descriptors. Different validation methods were used to evaluate the models and the results revealed the more applicability and predictive ability of the model generated by field descriptors (Q(2)LOO-CV=1, R(2)ext=0...

BACKGROUND: Previous reviews have identified 44 risk factors for poor early child development (ECD) in low- and middle-income countries. Further understanding of their relative influence and pathways is needed to inform the design of interventions targeting ECD. METHODS: We conducted path analyses of factors associated with 18-month language and motor development in four prospective cohorts of children who participated in trials conducted as part of the International Lipid-Based Nutrient Supplements (iLiNS) Project in Ghana (n = 1,023), Malawi (n = 675 and 1,385), and Burkina Faso (n = 1,122)...

BACKGROUND: Childhood psychiatric disorders and their symptoms evince both within-disorder (homotypic) and between-disorder (heterotypic) continuities. These continuities may be due to earlier symptoms causing later symptoms or, alternatively, that the same (unknown) causes (e.g., genetics) are operating across time. Applying a novel data analytic approach, we disentangle these two explanations. METHODS: Participants in a Norwegian community study were assessed biennially from 4 to 10 years of age with clinical interviews (n = 1,042)...

Stable isotope analysis is an important tool for characterising food web structure; however, interpretation of isotope data can often be flawed. For instance, lipid normalisation and trophic fractionation values are often assumed to be constant, but can vary considerably between ecosystems, species and tissues. Here, previously determined lipid normalisation equations and trophic fractionation values were re-evaluated using freshwater fish species from three rivers in the Upper Zambezian floodplain ecoregion in southern Africa...

Maternal effects are causal influences from mother to offspring beyond genetic information, and have lifelong consequences for multiple traits. Previously, we reported that mice whose mothers did not nurse properly had low birth weight followed by rapid fat accumulation and disturbed development of some organs. That pattern resembles metabolic syndromes known collectively as the thrifty phenotype, which is believed to be an adaptation to a stressful environment which prepares offspring for reduced nutrient supply...

Doctoral recipients in the biomedical sciences and STEM fields are showing increased interest in career opportunities beyond academic positions. While recent research has addressed the interests and preferences of doctoral trainees for non-academic careers, the strategies and resources that trainees use to prepare for a broad job market (non-academic) are poorly understood. The recent adaptation of the Social Cognitive Career Theory to explicitly highlight the interplay of contextual support mechanisms, individual career search efficacy, and self-adaptation of job search processes underscores the value of attention to this explicit career phase...

OBJECTIVE: To examine the association between maternal depression and anxiety disorders (MDAD) and child development assessed during the kindergarten year. METHODS: Administrative data from several health and social databases in Manitoba, Canada, were used to study 18,331 mother-child pairs. MDAD over the period from one year prior to the child's birth to the kindergarten year was defined using physician diagnoses and filled prescriptions. Child development was assessed during the kindergarten year using the Early Development Instrument (EDI) which measures vulnerability across five domains of development...

This study examines the genetic and environmental etiology underlying the development of oral language and reading skills, and the relationship between them, over a long period of developmental time spanning middle childhood and adolescence. It focuses particularly on the differential relationship between language and two different aspects of reading: reading fluency and reading comprehension. Structural equation models were applied to language and reading data at 7, 12, and 16 years from the large-scale TEDS twin study...

Nordic welfare states have been very successful at reducing poverty and inequality among their citizens. However, the presence of a strong social safety net in these countries has not solved the problem of socioeconomic exclusion, manifesting in such outcomes as chronic unemployment and welfare dependency. In an effort to understand this phenomenon, the current study builds on the assumption that psychological risk factors emerge as important determinants of socioeconomic disadvantage in an environment where ascribed characteristics have less impact on educational and occupational attainment...

Using multigroup structural equation modeling in a large sample of online-survey respondents (N = 6,744), the present study examined the reliability and dimensionality of the Male Role Norms Inventory-Short Form (MRNI-SF), a popular measurement of traditional masculinity ideology (TMI), and also tested measurement invariance between individuals that do and do not fit the White heterosexual male TMI reference group. Results indicated that (a) it is appropriate to model the MRNI-SF using either a bifactor or unidimensional model but not a second-order model, (b) the raw MRNI-SF total score is a suitable measure of the general TMI construct, (c) the raw self-reliance through mechanical skills and negativity toward sexual minorities subscale scores may be appropriate measures of their respective specific factors (akin to subscale factors), and (d) SEM or ipsatizing procedures should be used to model the 5 other specific factors, given the insufficient model-based reliability of their raw subscale scores...

The present study examined how stress reactions after traumatic events influence subjective well-being (SWB) via the indirect effect of posttraumatic growth (PTG) in two samples of Palestinian professional helpers from the Gaza Strip and West Bank ( n = 201). Using the General Health Questionnaire (GHQ-12) as a dependent measure of well-being, and PTGI-10, PANAS-20, WHO-5 BREF, and IES-13 questionnaires as independent variables, structural equation modelling (SEM) was used to examine whether: (a) cumulative trauma was negatively and directly related to subjective well-being; (b) levels of trauma were positively and directly related to posttraumatic growth; and (c) PTG was positively and directly related to subjective well-being...
