Ergonomic work analysis of airbus pilots job in Brazil

This article is the result of a case study of ergonomic work analysis carried out in a Brazilian airline company, focused on the safety of the activity of Airbus pilots from the company's national lines. The study was divided in three parts, each one with different approach. First step is how critical situations such as accidents and incidents are dealt with during flight. Then it comes to discuss about adversities found in the working place, the airbus cockpit, and the development of risk map. Last but not least, the study focused in how the irregular working journey compromises the biological clock of the pilots end may cause social issues.     

Identification of non-technical skills from the resilience engineering perspective: a case study of an electricity distributor

Training in non-technical skills (NTS) does not usually question the design of the work system, and thus focuses narrowly on workers as the unit of analysis. This study discusses how the identification of NTS, a major step for developing an NTS training program, might be re-interpreted from the perspective of resilience engineering (RE). This discussion is based on a case study of identifying NTS for electricians who perform emergency maintenance activities in an electricity distribution power line. The results of the case study point out that four data analysis procedures might operationalize the RE perspective: (a) identifying factors that make the work difficult and which could be integrated into NTS training scenarios; (b) identifying recommendations for re-designing the system, in order either to reduce or eliminate the need for NTS; (c) classifying the NTS into pragmatic categories, which are meaningful for workers; and (d) regarding the identification of NTS as an opportunity to give visibility to adaptations carried out by workers.     

Minority Stress,Parenting Styles,and Mental Health in Brazilian Homosexual Men

ABSTRACT

Homosexual men are constantly exposed to prejudice and violence in Brazil. The aim of this study was to investigate the relationship between minority stress, parenting styles, and indicators of mental health problems in a sample of homosexual men. Method: quantitative, cross-sectional, correlational, and retrospective design. Participants were 101 Brazilian men who selfidentified as homosexuals, aged between 18 and 55 years. Results: concealing sexual identity was a predictor of depression and stress. Parental responsiveness was associated with a lower incidence of enacted stigma and depression. Conclusions: the mental health of homosexual men can be negatively affected by the need to conceal their sexual orientation. Parental responsiveness is a protective factor in terms of experiencing enacted stigma and depression. The results found in the study may be useful for counselors and social workers who are working with LGBT people and their families.     

Internal and External Factors Underlying Variations in Adolescents’ Daily Optimal Experiences

This study investigated how the internal psychological states (i.e., challenge–skill perception, positive and negative affect, and effortless attention) and contextual features (i.e., activity and company) of momentary experiences relate to optimal experience in adolescents’ lives. Data were collected from 245 Portuguese adolescents (14–19 years old, 63% female) by using the experience sampling method. Multilevel modeling revealed that challenge–skill and positive affect were positively associated with optimal experience, while negative affect was negatively associated with optimal experience. Effortless attention mediated the associations between internal states and optimal experience, while activity and company only moderated some of these associations. These findings will inform practitioners about the factors that should be addressed in interventions with adolescents to promote optimal experiences in their lives.     

Individual differences in numerical representations of risk in health decision making: A fuzzy-trace theory approach

Fuzzy-trace theory predicts that decisionmakers process numerical information about risk at multiple levels in parallel: the simplest level, nominal (categorical some-none) gist, and at more fine-grained levels, involving relative comparison (ordinal less-more gist) and exact quantities (verbatim representations). However, little is known about how individual differences in these numerical representations relate to judgments and decisions, especially involving health tradeoffs and relative risks. To investigate these differences, we administered measures of categorical and ordinal gist representations of number, objective numeracy, and intelligence in two studies (Ns = 978 and 956). In both studies, categorical and ordinal gist representations of number predicted risk judgments and decisions beyond objective numeracy and intelligence. Participants with higher scores in categorical gist were more likely to choose options to avoid cancer recurrence risks; those who were higher in ordinal gist of numbers were more likely to discriminate relative risk of skin cancer; and those with higher scores in objective numeracy were more likely to choose options that were numerically superior overall in terms of relative risk of skin cancer and of genetic risks of breast cancer (e.g., lower numerical probability of cancer). Results support parallel-processing models that assume multiple representations of numerical information about risk, which vary in precision, and illustrate how individual differences in numerical representations are relevant to tradeoffs and risk comparisons in health decisions. These representations cannot be reduced to one another and explain psychological variations in risk processing that go beyond low versus high levels of objective numeracy.

Networks and Agricultural Development: The Case of Soybean Production and Consumption in Brazil

Diffusion theory and political economy are the two most common ways by which rural sociologists have explained the widespread use of agricultural innovations. In this paper, we argue, borrowing from science studies and using the empirical case of soybeans in Brazil, that the use of agricultural innovations is better understood as the result of the construction of networks of people and things. Thirty years ago soybean production in Brazil was insignificant. However, at that time a soybean network began to be formed. Initial actors were, among others, (1) soybean varieties produced in the United States, (2) wheat farmers located in the south of Brazil, and (3) soil in need of nitrogen, an expensive input for the new wheat varieties. State policies were no doubt important in consolidating that network. However, other persons, institutions and things were also necessary, including science and technology, the creation and/or expansion of farmers' organizations such as cooperatives, and the solution to the problem of photoperiod sensitivity in soybeans. We follow the soybean from its introduction in Brazil to its present status as an important crop. The overall context within which the soybean network began is also described. We conclude that the actor network approach is more congruent with the history of soybeans in Brazil than diffusion theory or political economy.     

Building a Latino Youth Program: Using Concept Mapping to Identify Community-Based Strategies for Success

ABSTRACT

In this study, a mixed methodology called concept mapping was used to bring 233 community members together to identify culturally relevant intervention strategies that could be used in developing a program for Latino youth. Three phases of data collection were completed to generate and rank 66 desirable strategies clustered around three goals: 1) staying in school, 2) developing positive social and family roles, and 3) bridging American and Latino cultures. An analysis of the rankings revealed differences in priorities between youth and adults. The results indicate that concept mapping can be useful in the development of community-based programs.     

“It’s a Dignity Thing”: Nursing Home Care Workers’ Use of Emotions1

This article examines how nursing home care workers use emotions to construct dignity at work. Previous scholarship has shown how the financial and organizational characteristics of nursing homes shape and constrain emotion work among staff. Using evidence gathered during 18 months of participant observation in two nursing homes and 65 interviews with staff, this article analyzes how, despite obstacles, nursing home care workers generated authentic emotional attachments to residents. Surprisingly, some staff members said they particularly appreciated working with residents difficult to control. They felt accomplished when such residents successfully transitioned from life at home to life in institutional care. Emotions created dignity for staff and induced compliance among residents. Emotions are not only generated by organizations and imposed on workers; staff themselves produced emotions—sometimes in ways consistent with organizational demands, and sometimes not—and they consistently found in their emotions a resource to manage the strains of their work lives.
