Proactive and politically skilled professionals: What is the relationship with affective occupational commitment?

The aim of this study is to extend research on employee affective commitment in three ways: (1) instead of organizational commitment the focus is on occupational commitment; (2) the role of proactive personality on affective occupational commitment is examined; and (3) occupational satisfaction is examined as a mediator and political skills as moderator in the relationship between proactive personality and affective occupational commitment. Two connected studies, one in a hospital located in the private sector and one in a university located in the public sector, are carried out in Pakistan, drawing on a total sample of over 400 employees. The results show that proactive personality is positively related to affective occupational commitment, and that occupational satisfaction partly mediates the relationship between proactive personality and affective occupational commitment. No effect is found for a moderator effect of political skills in the relationship between proactive personality and affective occupational commitment. Political skills however moderate the relationship between proactive personality and affective organizational commitment

Seasonal and spatial variations of saltmarsh benthic foraminiferal communities from North Norfolk, England

Time series foraminiferal data were obtained from samples collected from three sites at Brancaster Overy Staithe, Burnham Overy Staithe and Thornham on the North Norfolk coast over a 1-year period. At each collection point, six environmental variables—temperature, chlorophyll, sand, mud, pH and salinity—were also measured. The principle aim of this study was to examine the benthic foraminiferal fauna in regard to the temporal variability of foraminiferal abundance, seasonal trend, dominant species, species diversity and the impact of environmental variables on the foraminiferal communities in the top 1 cm of sediment over a 1-year time series. The foraminiferal assemblages at the three sites were dominated by three species: Haynesina germanica, Ammonia sp. and Elphidium williamsoni. Foraminiferal species showed considerable seasonal and temporal fluctuation throughout the year at the three investigated sites. The foraminiferal assemblage at the three low marsh zones showed a maximum abundance in autumn between September and November and a minimum abundance observed between July and August. There were two separate peaks in the abundance of Ammonia sp. and E. williamsoni, one in spring and another in autumn. In contrast, H. germanica showed a single peak in its abundance in autumn. A generalized additive modelling approach was used to explain the variation in the observed foraminiferal abundance and to estimate the significant impact of each of the environmental variables on living foraminiferal assemblages, with taxa abundance as the dependent variable. When included in the model as predictors, most of the environmental variables contributed little in explaining the observed variation in foraminiferal species abundance. However, the hypotheses for differences amongst sites, salinity and pH were significant and explained most of the variability in species relative abundance

Interbilayer-crosslinked multilamellar vesicles as synthetic vaccines for potent humoral and cellular immune responses

available in PMC 2011 September 1Vaccines based on recombinant proteins avoid the toxicity and antivector immunity associated with live vaccine (for example, viral) vectors, but their immunogenicity is poor, particularly for CD8+ T-cell responses. Synthetic particles carrying antigens and adjuvant molecules have been developed to enhance subunit vaccines, but in general these materials have failed to elicit CD8+ T-cell responses comparable to those for live vectors in preclinical animal models. Here, we describe interbilayer-crosslinked multilamellar vesicles formed by crosslinking headgroups of adjacent lipid bilayers within multilamellar vesicles. Interbilayer-crosslinked vesicles stably entrapped protein antigens in the vesicle core and lipid-based immunostimulatory molecules in the vesicle walls under extracellular conditions, but exhibited rapid release in the presence of endolysosomal lipases. We found that these antigen/adjuvant-carrying vesicles form an extremely potent whole-protein vaccine, eliciting endogenous T-cell and antibody responses comparable to those for the strongest vaccine vectors. These materials should enable a range of subunit vaccines and provide new possibilities for therapeutic protein delivery.Ragon Institute of MGH, MIT and HarvardBill & Melinda Gates FoundationUnited States.

Adolescent Protective and Risk Factors for Incarceration through Early Adulthood

With 2.3 million individuals incarcerated in the United States, incarceration remains a pressing social influence on health. While risk factors for incarceration are known, research has been slow to identify protective factors. Characterizing adolescent protective and risk factors for incarceration outcomes can inform interventions to prevent incarceration. Using survey data from the National Longitudinal Study of Adolescent to Adult Health, we tested the influence of adolescent risk and protective factors for incarceration of young people. We used ordinal logistic regressions, investigating the relationship between adolescent characteristics (wave I, grades 7–12) with two outcomes: incarceration onset (no incarceration, onset of incarceration as a juvenile, and onset of incarceration as an adult) and incarceration frequency (never incarcerated, incarcerated once, incarcerated more than once) during adolescence and into adulthood (N = 12,136, wave IV, ages 24–32). Adolescent protective factors against incarceration onset and higher incarceration frequency centered on education, including a higher grade point average and a higher likelihood of having future plans to attend college. Risk factors included disruptive behavior, physical or sexual abuse in childhood, parental incarceration, and living with a stepfather figure. Stratified analyses suggested that Latinos may have unique risk profiles compared to African American and White youth. The educational system may be a locus for protective interventions promoting academic achievement and educational aspirations. Understanding both incarceration risk and protective factors may allow interventions to be tailored appropriately

Cross-Cultural Management

Culture is something socially constructed and historically infused in people’s beliefs, perceptions, and behavior. It has been defined as “the collective programming of the mind which distinguishes the members of one category of people from another” (Hofstede 1980). Since business is made by people, all organizational activities, from leadership to decision-making, are somehow impacted by culture. Cross-cultural management is the group of strategies and policies, usually adopted by international or multinational firms, aiming to improve the coordination and cooperation among employees and between staff and external business actors that embody different behavioral norms and interpersonal expectations due to their respective national cultures. The basic assumption of cross-cultural management is that there is the potential of misunderstandings in the context of relationships between individuals and organizations from differing cultural backgrounds. From the 1970s to the 1990s, culture was described as a barrier to interaction and source of frictions. Yet, recently, the idea of culture as a resource of organizational learning and competitive advantage also emerged. Companies that leverage from their multicultural workforce can better satisfy different clients and speed up knowledge transfers. Therefore, the goal of cross-cultural management studies is to help identify the characteristics of particular cultures, make comparisons, and provide insights on how to conduct the cross-cultural interactions to both avoid conflicts and get benefits from the correct handling of cultural differences
