Cognitive-ergonomics and instructional aspects of e-learning courses

This paper presents an analysis of cognitive-ergonomic aspects of e-learning courses, offered by an organism from Brazilian Public Administration. The Cognitive Ergonomic studies conductive and cognitive aspects concerning to the relation between human, physics elements and social elements of the work space. From that usability aspects were evaluated by these points: i) visualization; ii) text comprehension lecture; iii) memory; iv) interface; v) instructional design; and vi) attention and learning. That survey is characterized as having been applied using the following techniques: (1) bibliographic survey, (2) field survey and (3) analysis of the documents. It was chosen the semi-structured questionnaire as the main method of data collection. About the interacting with artifacts, the interface of the courses is classified as direct engagement, because it allows the user to get the feeling that acts directly on the objects. Although the courses are well-structured they have flaws that will be discussed below. Even with these problems, the courses have a good degree of usability.     

The use software ERGOSHOW in the education of health and safety at work to regardin the safety to children

It is believed that health and safety of workers should be worked with children and early teenagers, the perspective that adults are more aware of these issues by providing them with health and quality of life in their daily lives, this is want the ERGOSHOW. The choice of media means for transmitting content of Ergonomics, Health and Safety (OSH) is justified because of the great popularity of computer games are among the public of the study, thereby providing a greater assimilation of the content worked. Therefore, the aim of this study was to work with OSH issues related to children between 08 and 12 years old, city of, State of Minas Gerais, Brazil. To achieve this we used the software ERGOSHOW, quizzes, and lecture. One can see that the use of multimedia tools in the learning, especially when considering the reports of mothers according to the different behavior of children after the development of activities, such as parents in correcting posture in relation to computer use.     

The use of simple reparameterizations to improve the efficiency of Markov chain Monte Carlo estimation for multilevel models with applications to discrete time survival models

Summary.  We consider the application of Markov chain Monte Carlo (MCMC) estimation methods to random-effects models and in particular the family of discrete time survival models. Survival models can be used in many situations in the medical and social sciences and we illustrate their use through two examples that differ in terms of both substantive area and data structure. A multilevel discrete time survival analysis involves expanding the data set so that the model can be cast as a standard multilevel binary response model. For such models it has been shown that MCMC methods have advantages in terms of reducing estimate bias. However, the data expansion results in very large data sets for which MCMC estimation is often slow and can produce chains that exhibit poor mixing. Any way of improving the mixing will result in both speeding up the methods and more confidence in the estimates that are produced. The MCMC methodological literature is full of alternative algorithms designed to improve mixing of chains and we describe three reparameterization techniques that are easy to implement in available software. We consider two examples of multilevel survival analysis: incidence of mastitis in dairy cattle and contraceptive use dynamics in Indonesia. For each application we show where the reparameterization techniques can be used and assess their performance.     

Electronic Gaming Machine (EGM) Environments: Market Segments and Risk

This study used a marketing-research paradigm to explore gamblers’ attraction to EGMs based on different elements of the environment. A select set of environmental features was sourced from a prior study (Thorne et al. in J Gambl Issues 2016b), and a discrete choice experiment was conducted through an online survey. Using the same dataset first described by Rockloff et al. (EGM Environments that contribute to excess consumption and harm, 2015), a sample of 245 EGM gamblers were sourced from clubs in Victoria, Australia, and 7516 gamblers from an Australian national online survey-panel. Participants’ choices amongst sets of hypothetical gambling environments allowed for an estimation of the implied individual-level utilities for each feature (e.g., general sounds, location, etc.). K-means clustering on these utilities identified four unique market segments for EGM gambling, representing four different types of consumers. The segments were named according to their dominant features: Social, Value, High Roller and Internet. We found that the environments orientated towards the Social and Value segments were most conducive to attracting players with relatively few gambling problems, while the High Roller and Internet-focused environments had greater appeal for players with problems and vulnerabilities. This study has generated new insights into the kinds of gambling environments that are most consistent with safe play.     

Could EGM player-tracking systems help link gamblers to treatment services in Australia: a thematic analysis of counsellor and community educators’ perspectives

There are a number of different pathways to care that people experiencing problems with gambling may pursue. The current research examined the potential of player-tracking systems, such as pre-commitment technology or loyalty cards, to improve the delivery of links to treatment. Thirty-three key informants from gambling treatment and community education in Australia were interviewed about the potential contributions of these technologies to helping link gamblers with problems to treatment services. Thematic analysis revealed three broad considerations for effective links to treatment using these technologies. First, links need to be appropriate in terms of the multitude of problems (other than gambling) that people might face with customized links appropriate to a gambler’s circumstances. Second, the presentation of the links should make them easy to notice and appropriately timed. Third, links should be provided as part of a broader strategy of harm minimization; by recognizing where people are in terms of behavioural change; providing positively framed guidance; and maintaining consistency with public health approaches. This research provides guidance based on informed expert opinion on what features of technology-driven links-to-treatment are likely to meet with greatest success.     

Is Ethnic Identity a Buffer? Exploring the Relations Between Racial Microaggressions and Depressive Symptoms Among Asian-American Individuals

ABSTRACT

This study explores the moderating role of ethnic identity in the relations between racial microaggressions and depressive symptoms. Using survey data from 353 Asian-American college students, we found that racial microaggressions significantly predicted depressive symptoms and accounted for 24% of the variance in a hierarchical multiple regression analysis. In addition, ethnic identity moderated the relations between racial microaggressions and depressive symptoms. Thus, ethnic identity buffers Asian-Americans against the negative mental health effects of racial microaggressions. Implications for research and practice in the field of social work are discussed.     

Let’s go out for a drink after work! The relation between leisure time spent with colleagues and employees’ life satisfaction

Despite the tremendous research studying the factors that influence employees’ well-being, the effect of what happens when leisure time is spent with colleagues remains yet unexamined. Building on the Conversation of Resource Theory, we propose that leisure time spent with colleagues could be understood as a resource, especially for those individuals who have few friends at their workplace. In a cross-sectional design, 136 university employees provided information about the number of friends they have at work, the amount of leisure time spent with befriended colleagues, and their life satisfaction. Results suggest that a larger network of friends at work is positively associated with life satisfaction. Furthermore, the effect of the number of friends at work on life satisfaction is moderated by the amount of leisure time spent with befriended colleagues. Employees who have few friends at work report more life satisfaction, if they spend more leisure time with befriended colleagues, whereas such an effect was not found for employees with a large friend network at work. These results are placed into the context of current discussions about work-life-blending.
