Impact of Job-Related Well-Being on the Relationship of Self-Efficacy With Burnout

Abstract The levels of job-related affective well-being and occupational self-efficacy may act as protective factors against the development of burnout. Therefore, this study investigated the role of positive and negative affect as a mediator in the relations between occupational self-efficacy and the dimensions of burnout. The research participants were 584 professionals (87% female), mean age 37.8 (SD= 10.8). The results of the structural equation modeling analysis indicated that the relations of occupational self-efficacy with emotional exhaustion and depersonalization were completely mediated by positive and negative affect. The relation between occupational self-efficacy and personal accomplishment was partially mediated by positive affect. Occupational self-efficacy was positively associated to positive affect and negatively related to negative affect. This study adds by showing the importance of developing interventions that promote the experience of positive affect and reduction of negative affect in occupational settings as a preventive strategy of burnout

The aquaculture supply chain in the time of covid-19 pandemic: Vulnerability, resilience, solutions and priorities at the global scale

The COVID-19 global pandemic has had severe, unpredictable and synchronous impacts on all levels of perishable food supply chains (PFSC), across multiple sectors and spatial scales. Aquaculture plays a vital and rapidly expanding role in food security, in some cases overtaking wild caught fisheries in the production of high-quality animal protein in this PFSC. We performed a rapid global assessment to evaluate the effects of the COVID-19 pandemic and related emerging control measures on the aquaculture supply chain. Socio-economic effects of the pandemic were analysed by surveying the perceptions of stakeholders, who were asked to describe potential supply-side disruption, vulnerabilities and resilience patterns along the production pipeline with four main supply chain components: a) hatchery, b) production/processing, c) distribution/logistics and d) market. We also assessed different farming strategies, comparing land- vs. sea-based systems; extensive vs. intensive methods; and with and without integrated multi-trophic aquaculture, IMTA. In addition to evaluating levels and sources of economic distress, interviewees were asked to identify mitigation solutions adopted at local / internal (i.e., farm-site) scales, and to express their preference on national / external scale mitigation measures among a set of a priori options. Survey responses identified the potential causes of disruption, ripple effects, sources of food insecurity, and socio-economic conflicts. They also pointed to various levels of mitigation strategies. The collated evidence represents a first baseline useful to address future disaster-driven responses, to reinforce the resilience of the sector and to facilitate the design reconstruction plans and mitigation measures, such as financial aid strategies
