Lent and Brown's (2006, 2008) social cognitive model of work well-being was tested in two samples of African college students, one from Angola ( N = 241) and one from Mozambique ( N = 425). Participants completed domain-specific measures of academic self-efficacy, environmental support, goal progress, and satisfaction, along with measures of global positive affect and life satisfaction. Path analyses indicated that the model fit the data well overall, both in the full sample and in separate sub-samples by country and gender. Contrary to expectations, however, self-efficacy predicted academic satisfaction only indirectly, via goal progress; and goal progress predicted life satisfaction only indirectly, via academic satisfaction. The predictors accounted for substantial portions of the variance in both academic domain satisfaction and life satisfaction. Implications for research and practice involving the social cognitive model are considered.

Gastric cancer remains a serious health concern worldwide. Patients would greatly benefit from the discovery of new biomarkers that predict outcome more accurately and allow better treatment and follow-up decisions. Here, we used a retrospective, observational study to assess the expression and prognostic value of the transcription factors SOX2 and CDX2 in gastric cancer. SOX2, CDX2, MUC5AC and MUC2 expression were assessed in 201 gastric tumors by immunohistochemistry. SOX2 and CDX2 expression were crossed with clinicopathological and follow-up data to determine their impact on tumor behavior and outcome. Moreover, SOX2 locus copy number status was assessed by FISH (N = 21) and Copy Number Variation Assay (N = 62). SOX2 was expressed in 52% of the gastric tumors and was significantly associated with male gender, T stage and N stage. Moreover, SOX2 expression predicted poorer patient survival, and the combination with CDX2 defined two molecular phenotypes, SOX2+CDX2- versus SOX2-CDX2+, that predict the worst and the best long-term patients’ outcome. These profiles combined with clinicopathological parameters stratify the prognosis of patients with intestinal and expanding tumors and in those without signs of venous invasion. Finally, SOX2 locus copy number gains were found in 93% of the samples reaching the amplification threshold in 14% and significantly associating with protein expression. We showed, for the first time, that SOX2 combined with CDX2 expression profile in gastric cancer segregate patients into different prognostic groups, complementing the clinicopathological information. We further demonstrate a molecular mechanism for SOX2 expression in a subset of gastric cancer cases.

The present study aims to test the factor structure of two sleep questionnaires and their internal consistency in a sample of adolescents and their respective parents and to evaluate the validity and robustness of a three-dimensional model about sleep, addressing nine subcategories related to sleep habits, personal and environmental factors. Participants were 654 adolescents from Portuguese schools, who completed "My Sleep and I" questionnaire, and 664 parents who completed "My child׳s sleep" questionnaire; to them confirmatory factor analysis was applied. Confirmatory factor analysis indicate that a nine-factor model has better fit indices compared with the others tested models for both samples (adolescents: χ (2)/df (Chi-square/degrees of freedom)=2.59, Comparative Fit Index (CFI)=.82, Goodness-of-Fit Index (GFI)=.92, Root Mean Square Error of Approximation (RMSEA)=.049, Expected Cross-Validation Index (ECVI)=1.416; Parents: χ (2)/df=2.89, CFI=.85, GFI=.91, RMSEA=.053, ECVI=1.528). Moreover, the comparison of the models through Δχ (2) index (chi-square difference between rival models) indicates a better fit for this model, Δχ (2) (24)=186.5, p<.001 for adolescents and Δχ (2) (24)=209, p<.001 for parents. Also, the three second-order factors have good internal consistency, convergent and discriminant validity for all factors in both samples. Results postulate that the three factors and their nine subcategories account for correlations between sleep habits, self-perceptions and knowledge about sleep.

Introduction: Service-Learning (SL) is an innovative teaching-learning proposal with an increasingly wide application in higher education. Previous studies show its potential to generate positive personal, academic, social and citizenship outcomes among students who participate in it. But studies that help understand in depth its real impact, particularly in comparison with more traditional teaching-learning contexts, are still scarce. Method: This study explores the effects of Service-Learning on 122 university students, who were attending Psychology (n = 80), Social Work (SW; n = 19) and Applied Foreign Languages (AFL; n = 23) degree courses. These participants were organized into service-learning and traditional teaching-learning groups and assessed on expectations and impact of the service-experience, development of social and civic skills, and life goals.Results: Results show significant differences between pre- and post-tests in life goals, namely an increase in hedonistic and wellbeing goals for Psychology students, political, hedonistic, religious, personal development, and wellbeing goals for SW students, and social and wellbeing goals for AFL students. Students in Psychology and AFL increased their expectations with the service and students in the AFL developed more pro-social behaviors.Discussion: These results are encouraging for the expansion of this transformative teaching-learning practice to courses of different scientific areas, although with some specificities, with the purpose of contributing to a more responsible, critical and participatory society in the creation of the common good.

Introduction: In the current worldwide labor context, where a disruption took place and employees experience.Methods: Participated in this study 739 European hybrid workers who fulfilled an online assessment protocol.Results: Results indicate that higher ages, higher educational levels, being married, having children, working.Discussion: This study makes a unique contribution to the extant research on hybrid workers’ careers, specifically.
