Conservation Management of EU Priority Habitats after Collapse of Traditional Pastoralism: Navigating Socioecological Transitions in Mountain Rangeland

Agricultural abandonment is a major driver of change in rural landscapes. Assumed to provide beneficial results to the environment and the conservation of biota, rural abandonment triggers landscape and biotic homogenization and loss of valuable species and habitats. This article focuses on the ecological effects and conservation challenges of shifts in extensive grazing regimes on marginal pastureland of Mediterranean mountains. We conceptualize a navigated socioecological transition toward conservation‐oriented management after the collapse of historical land systems. The article provides examples from the LIFE+ project “Higro,” developed in mountainous protected areas in Portugal, of how management for conservation could sustain disturbance‐dependent habitats. We argue that actively and regularly managing large habitat areas should be envisaged as a short‐term approach to limit the immediate effects of rural abandonment. A gradual integration of conservation targets with other activities in changing rural economies is necessary to foster long‐term conservation of species and habitats, building on the link between conservation‐oriented habitat management and ecosystem services in rural landscapes. Conservation goals should run alongside recovery of social systems and innovation applied to traditional sources of income. This parallel development would contribute to building up social‐ecological resilience by maintaining a diversity of social and ecological capital in rural areas.     

Musculoskeletal symptoms and work ability among agricultural machinery operators

Those subjects whose employment has physical demands present more frequently musculoskeletal symptoms than others. The agricultural sector activities include tasks with important physical demands that may have a negative impact in the workers health. The aim of this study was to evaluate the presence of musculoskeletal symptoms and its association with work ability in agricultural machinery operators. It is a cross-sectional study. The participants (n = 204) answered a self-administered questionnaire on demographics, work and lifestyle characteristics, Work Ability Index and the Nordic Musculoskeletal Symptoms Questionnaire. The response rate was 89.78%. The mean age of the workers was 32.3 years, and 47.1% of them reported musculoskeletal symptoms at least one body part over the past 12 months. Those subjects who presented work ability index <37 points, 87.5% reported some kind of musculoskeletal symptom. This study showed that the work ability was significantly (p ≤ 0.05) correlated to musculoskeletal symptoms presence. It is recommended that measures to promote and improve the work ability are designed and deployed based on musculoskeletal disorders prevention.     

Ports of Mucuripe and Pecém, Ceará, Brazil: restructuring process and its impact on workers' health

This paper presents a comparative study of working conditions and health hazards of two ports in the state of Ceará: Mucuripe and Pecém, focusing workers in the various categories involved in the operational activities of the two ports. The aim is to investigate changes implemented by the restructuring process of ports arising from the Port Modernization Act. In the case of Ceará, the organization and control of work at the mentioned ports occur differently: Mucuripe, the oldest port, had to adapt to the changes enforced by the Modernization Act and Pecém, called Port Terminal, inaugurated in 2001, "was born modern". To achieve our objective, we carried out field work, using Ergonomic Work Analysis. Systematic observations were made of the various activities carried out by workers, as well as interviews with managers, workers and trade unionists. Container operations and other activities of the two ports were recorded in film and presented to groups of workers (focus groups) in order to better understand work organization and the main differences in tasks carried out in the two ports. Each reality presents different characteristics regarding port operations, type of work and labor control. Results indicate that due to the technological innovations, the restructuring process reduced some risks, but brought new occupational hazards and intensification of work.     

Integer-Valued Self-Exciting Threshold Autoregressive Processes

In this article, we introduce a class of self-exciting threshold integer-valued autoregressive models driven by independent Poisson-distributed random variables. Basic probabilistic and statistical properties of this class of models are discussed. Moreover, parameter estimation is also addressed. Specifically, the methods of estimation under analysis are the least squares-type and likelihood-based ones. Their performance is compared through a simulation study.     

Psychosocial Assistance for Youth: Toward Reconstruction for Peace in Angola

Following decades of war, Angolan youth are at risk of continuing cycles of violence and need support in developing positive behaviors and social roles. Accordingly, a community-based program, conducted in Angola 1998–2001, taught youth life skills, provided peer support and peace education, educated adults about youth, and engaged youth as workers on community development projects. The main results included increased adult awareness of the situation and needs of youth, improved youth-adult relations, reduced perceptions of youth as troublemakers, reduced fighting between youth, increased community planning, and increased perceptions that youth make a positive contribution to the community. The results suggest that a dual focus on youth and community development contributes to peacebuilding and the disruption of cycles of violence.
