Social Support and Self-Efficacy on Turnover Intentions: The Mediating Role of Conflict and Commitment

Turnover intentions are a phenomenon that affects the life of organizations and causes highly negative consequences. Based on previous studies, it is possible to consider antecedents to turnover in terms of both individual and social perceived resources, which previous research does not usually examine simultaneously. The aim of this study was to explore the role of both resources (individual and social) on turnover intentions. Thus, we hypothesized that perceived social support and self-efficacy have an impact on turnover intentions and that this relationship is mediated by interpersonal conflict and Affective Commitment. A total of 392 Italian employees completed a self-report questionnaire. A structural equation model was tested. The results showed that interpersonal conflict and Affective Commitment fully mediated the relationship between social support, self-efficacy and turnover intentions. Practical implications are discussed

Gender and country differences in academic motivation, coping strategies, and academic burnout in a sample of Italian and Russian first-year university students

Background: The first year of university represents a challenging period that requires students to make significant investments in adaptive resources to face the new academic environment. The present study intends to contribute to the controversial discussion of gender differences in academic motivation, coping strategies, and academic burnout. This cross-sectional study examined above-mentioned constructs among first-year university students in a cross-cultural context. Methods: The sample consisted of 637 Italian and 496 Russian first-year university students (n = 1133), 40.3% of whom were females. The participants’ ages ranged from 17 to 23 years, with a mean age of 18.75 years (SD = 1.07). To assess academic motivation, coping strategies, and academic burnout, participants responded to the Academic Motivation Scale (AMS), the Coping Inventory for Stressful Situations (CISS), and the Maslach Burnout Inventory–Student Survey (MBI–SS) application. Results: The findings reveal gender and country differences in academic motivation, emotion and avoidance oriented coping strategies, and emotional exhaustion and expands previous studies in this educational area. Conclusion: Given the technical nature of the research topic, the target audience for our study is academic career guidance practitioners, who can apply the findings to the design of effective programmes aimed at improving positive academic goals and reducing the tendency to switch academic courses or abandon the university among first-year students

Continuous cell lines and immune ascitic fluid pools in arbovirus detection

Pour la recherche et l'isolement des arbovirus, des expérimentations successives nous ont amenés à utiliser, parmi les lignées de cellules en culture continue dont l'utilisation est préconisée par l'OMS, les deux systèmes cellulaires MOS61 (cellules de #Aedes pseudoscutellaris$) et Vero. La détection des virus dans les sytèmes cellulaires est réalisée à l'aide de 7 pools de 10 ascites hyperimmunes polyvalentes. Cette technique permet la mise en évidence de 70 sur 80 arbovirus transmis par les moustiques en Afrique, et permet de détecter très facilement les associations d'arbovirus grâce aux ascites immunes monospécifiques ou monoclonales (dengue-1-2-3-4 et fièvre jaune).

Proactive, boundaryless, and confident graduates entering the labour market: does need for cognitive closure play a role as a moderator?

The university to work transition is a crucial and delicate stage for graduates, as it involves an essential change of role. Previous studies have shown that proactive personality, boundaryless mind-set and career self-efficacy are critical variables for a successful labour market integration/entry. This study analyzes the involvement of the need for cognitive closure as an individual variable that can both favor and hinder this process. Specifically, this work examines the moderating role of need for cognitive closure in the indirect association between proactive personality and career self-efficacy through boundaryless mind-set in a sample of 762 adults enrolled at the university or recently graduated therein. Results showed that career self-efficacy was positively predicted by proactive personality and boundaryless mind-set. Although a significant indirect effect was present thus confirming our first hypothesis, it did not vary depending on the need for cognitive closure proving that need for cognitive closure did not act as a moderator of this indirect association, hence not supporting our second hypothesis. These findings were discussed concerning the complexity of students’ choices in transition and the nature of the information processing process needed for those choices

Microbial biofilm community structure and composition on the lithic substrates of Herculaneum Suburban Baths

In this work, we want to investigate the impact of different substrates and different environmental condition on the biofilm communities growing on plaster, marble, and mortar substrates inside the Herculaneum Suburban Baths. To do so, we measured environmental conditions and sampled biofilm communities along the walls of the baths and used culture-dependent and -independent molecular techniques (DGGE) to identify the species at each sampling sites. We used the species pool to infer structure and richness of communities within each site in each substrate, and confocal light scanning microscopy to assess the three-dimensional structure of the sampled biofilms. To gather further insights, we built a meta-community network and used its local realizations to analyze co-occurrence patterns of species. We found that light is a limiting factor in the baths environment, that moving along sites equals moving along an irradiation gradient, and that such gradient shapes the community structure, de facto separating a dark community, rich in Bacteria, Fungi and cyanobacteria, from two dim communities, rich in Chlorophyta. Almost all sites are dominated by photoautotrophs, with Fungi and Bacteria relegated to the role of rare species., and structural properties of biofilms are not consistent within the same substrate. We conclude that the Herculaneum suburban baths are an environment-shaped community, where one dark community (plaster) and one dim community (mortar) provides species to a “midway” community (marble)

Caractères cliniques et épidémiologiques de la dengue 2 au Sénégal

Les auteurs rappellent les faits historiques, cliniques et épidémiologiques concernant l'infection par les virus de la dengue en Afrique. Ils énumèrent les lieux, les hôtes et les circonstances de l'isolement de différentes souches africaines et rappellent le cycle sauvage du virus dengue 2 au Sénégal. L'isolement de deux souches humaines, pendant l'épizootie de 1990, est en faveur d'un cycle selvatique. Il s'agit en effet des premiers cas humains concomitants d'une épizootie au Sénégal. Les observations cliniques de ces deux cas sont celles d'une arbovirose mineure, sans syndrome de choc ni manifestations hémorragiques, soulignant la pathogénicité atténuée du virus dengue 2 au Sénégal comme dans les autres pays d'Afrique. De récents travaux d'épidémiologie moléculaire ont mis en évidence des caractères génotypiques particuliers de certaines souches africaines par rapport à celles rencontrées dans les régions Pacifique ou Caraïbes.

Gut microbiome structure and adrenocortical activity in dogs with aggressive and phobic behavioral disorders

Accompanying human beings since the Paleolithic period, dogs has been recently regarded as a reliable model for the study of the gut microbiome connections with health and disease. In order to provide some glimpses on the connections between the gut microbiome layout and host behavior, we profiled the phylogenetic composition and structure of the canine gut microbiome of dogs with aggressive (n = 11), phobic (n = 13) and normal behavior (n = 18). Hormones\u2019 determination was made through Radio Immuno-Assay (RIA), and next generation sequencing of the V3\u2013V4 gene region of the bacterial 16S rRNA was employed to determine gut microbiome composition. Our results did not evidence any significant differences of hormonal levels between the three groups. According to our findings, aggressive behavioral disorder was found to be characterized by a peculiar gut microbiome structure, with high biodiversity and enrichment in generally subdominant bacterial genera (i.e. Catenibacterium and Megamonas). On the other hand, phobic dogs were enriched in Lactobacillus, a bacterial genus with known probiotic and psychobiotic properties. Although further studies are needed to validate our findings, our work supports the intriguing opportunity that different behavioral phenotypes in dogs may be associated with peculiar gut microbiome layouts, suggesting possible connections between the gut microbiome and the central nervous system and indicating the possible adoption of probiotic interventions aimed at restoring a balanced host-symbiont interplay for mitigating behavioral disorders
