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

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

Upland rice development under a no-tillage system as a function of gypsum and phosphorus.

the objective of this work was to determine the effect of the combination of gypsum applied to the soil surface without tillage and P applied in the sowing furrow on soil attributes and the plant height, number of panicles m-1 and grain yield of upland rice cultivated in an no-tillage system

Produtividade do feijão-comum afetado por população de plantas.

A população de plantas afeta diretamente a incidência de luz e fotossíntese, doenças e plantas daninhas, colheita, acamamento, aproveitamento de água e fertilizantes e gastos com sementes da maioria das culturas agrícolas. Além disso, é importante se determinar a população ideal de plantas por área das novas cultivares de feijão-comum visando obter o máximo potencial produtivo de cada material genético. O objetivo desse trabalho foi de determinar o efeito de população de plantas nos componentes de produção e produtividade de grãos da cultivar de feijão-comum BRS Estilo. O delineamento experimental foi em blocos ao acaso com cinco tratamentos e seis repetições. Os tratamentos foram compostos pelo número de sementes por metro de BRS Estilo (4, 8, 12, 16 e 20 sementes m-1). O aumento da população de plantas proporcionou redução na massa de matéria seca, número de vagens por planta, número de grãos por vagem, massa de 100 grãos e produtividade de grãos do feijão-comum cultivar BRS Estilo. Com base em nossos resultados a densidade ideal foi de quatro plantas por metro, ou 22.222 plantas por hectare.Comunicação

Bovine paratuberculosis: results of a control plan in 64 dairy farms in a 4-year period

Paratuberculosis is considered one of the most economically devastating infectious diseases of domestic livestock, and the most effective control strategy is a combination of 'test-and-cull' and on-farm biosecurity measures. In Italy, a Voluntary National Control Plan (VNCP) and guidelines have been introduced to reduce the impact of the disease, and farmers can voluntarily enroll in the control plan. The main aims of this study were: i) the description of the trend over a 4-year period on total, within-herd (WH) and between herd (BH) apparent seroprevalences observed in 64 dairy herds members of a mutual company located in Italy after the introduction of a proposed "Customized Control Plan" (CCP); ii) the evaluation of its effectiveness in terms of percentage of participating farms that decided to join the VNCP. Analyses on serum samples were performed with Enzyme-Linked Immuno Sorbent Assay (ELISA) method and revealed a general decrease in both total, WH and BH apparent seroprevalence. Total average apparent seroprevalence decreased from 2.39% in 2017 to 1% in 2020. Negative herds raised from 51.9% in 2017 to 71.1% in 2020, while farms with WH apparent seroprevalence > 5% decreased from 17.3% in 2017 to 4.4% in 2020. BH apparent seroprevalence decreased from 51.2% in 2017 to 29.2% in 2020. Among the 52 out of 64 herds that accepted to continue the proposed CCP after the first year, 41 (78.8%) joined in 2020 the VNCP, that assessed the health ranking of the herds. The results provide evidence that a control plan based on a farm-specific strategy and a subsidized testing process can effectively reduce the impact of paratuberculosis in dairy herds, especially in convincing farmers to continue in paratuberculosis control by joining the VNCP, including them in a National context and increasing their awareness of the disease
