This paper aimed mainly to investigate the relationships between Brazilian Loneliness Scale (UCLA-BR) and the levels of depression, anxiety and stress in Brazilian college students. These concepts were assessed using validated scales (Patient Health Questionnaire - PHQ-9, Depression, Anxiety and Stress Scale - DASS-21, Beck Anxiety Inventory - BAI and Lipp Stress Symptom Inventory - ISSL). A total of 325 college students participated and responded all the instruments. Descriptive, correlational and group differences analyzes were conducted. The prevalence of depression, anxiety and stress varied depending on the instrument used. UCLA-BR presented evidence of validity based on relationships with depression, anxiety and stress, especially depression (assessed by DASS-21). Analysis of measurement scales can help to understand aspects of college students’ mental health.

Oil and gas resources have been considered valuable assets, associated with potential conflicts due to distinct interests of many agents involved in their exploration, such as producing and consuming countries, governments and companies. These conflicts can show up under many situations and market conditions, such as partnerships, joint development, optimal outputs and reserve maximization. Game theory is known as a methodology that improves the decision-making processes by better understanding the players' specific motivations, strategic interactions and payoff estimation. A widely used framework for modeling social and economic phenomena is the 2 x 2 strategic games, of which include classical forms such as Prisoner's Dilemma, Stag Hunt, and Battle of Sexes. Therefore, this paper proposes to examine relevant realistic and real-world cases of the oil and gas industry in the form of 2 x 2 strategic games, aiming to investigate game theory approaches to aid in the discussion and resolution of the main dilemmas faced.

Resumo Este estudo mapeou perfis de idosos praticantes de atividades prazerosas e relacionou tais perfis com variáveis sociodemográficas e estado funcional. Idosos (n=330) sem comprometimento cognitivo, residentes da comunidade e com diferentes níveis de vulnerabilidade social (acessado pelo Índice Paulista de Vulnerabilidade Social) responderam um questionário sociodemográfico, a escala de Pfeffer (funcionalidade) e o OPPES-BR (prática de atividades prazerosas). Por meio da análise de cluster combinando-se o método hierárquico e não-hierárquico foram identificados cinco perfis de idosos: muito ativos; muito ativos sociáveis; minimalistas; pouco ativos contemplativos; e pouco ativos intelectuais. Manter alta frequência em diversos tipos de atividades prazerosas associou-se à maior escolaridade, menor vulnerabilidade social e menor dependência funcional. O perfil dos pouco ativos contemplativos foi o mais vulnerável, com maior declínio funcional, vulnerabilidade social e taxa de analfabetismo. Diante da diversidade de perfis de idosos, são necessárias políticas públicas favorecedoras ao acesso a atividades prazerosas, principalmente aos mais vulneráveis.
