The industrial athlete?

Many similarities can be drawn between the athletic and industrial population. It is time for a shift in the approach toward injured workers utilizing a sports medicine perspective. We must think of workers as industrial athletes and recognize that the sports medicine model can be appropriately adapted to the injured worker. This model includes prevention, early intervention/identification, training and conditioning, and progressive treatment. Sports medicine rehabilitation concepts include treating the entire kinetic chain that is associated with a specific injury and the SAID principle (Specific Adaptations to Imposed Demands).     

Adoption Issues: Preparation of Psychologists and an Evaluation of the Need for Continuing Education

This study is an investigation of the level of preparation psychologists have in dealing with adoption issues and an assessment of the need for further education in treating triad members. A questionnaire was mailed to 497 psychologists randomly selected from the National Register of Health Service Providers in Psychology who received doctoral degrees between the years of 1990 and 1996. Two hundred and ten psychologists, all of whom were currently treating clients, participated in the study. Psychologists completed a Likert rating of their sense of preparation to treat triad members. The largest group (51%) rated themselves as Somewhat prepared, with the second largest group (23%) rating themselves as Not very prepared. Ninety percent reported they needed more education in adoption, and 81% reported interest in taking a continuing education course in adoption. Of the 210 participants, only 67 reported taking courses that dealt with adoption as part of their formal education. Of those psychologists who reported taking courses that involved adoption, they averaged only 1.3 courses during their undergraduate education, and 1.5 courses during graduate education, while the remaining 143 psychologists received no education in this area. When one considers the proportion of triad members seen clinically, this study suggests psychologists need more education and background information about the effects of the adoption process.     

Codes of ethics and firm size: A stakeholder approach to strategic planning

A firm's capital budgeting and strategic planning decisions have the potential to affect many groups of people called stakeholders. A stakeholder is any group or individual who can affect or is affected by the achievement of the firm's objectives. This study examines whether the presence of a code of ethics that specifically addresses capital budgeting/strategic planning decisions will significantly raise the awareness of social responsibility during the long-run planning process. This study also examines whether firm size is associated with the awareness of social responsibility during the long-run planning process. Support was found that a code of ethics that addresses long-range planning is associated with higher awareness during the planning process. Firm size was not found to be statistically different.     

Machine learning for multi-criteria inventory classification applied to intermittent demand

Multi-criteria inventory classification groups inventory items into classes, each of which is managed by a specific re-order policy according to its priority. However, the tasks of inventory classification and control are not carried out jointly if the classification criteria and the classification approach are not robustly established from an inventory-cost perspective. Exhaustive simulations at the single item level of the inventory system would directly solve this issue by searching for the best re-order policy per item, thus achieving the subsequent optimal classification without resorting to any multi-criteria classification method. However, this would be very time-consuming in real settings, where a large number of items need to be managed simultaneously.

In this article, a reduction in simulation effort is achieved by extracting from the population of items a sample on which to perform an exhaustive search of best re-order policies per item; the lowest cost classification of in-sample items is, therefore, achieved. Then, in line with the increasing need for ICT tools in the production management of Industry 4.0 systems, supervised classifiers from the machine learning research field (i.e. support vector machines with a Gaussian kernel and deep neural networks) are trained on these in-sample items to learn to classify the out-of-sample items solely based on the values they show on the features (i.e. classification criteria). The inventory system adopted here is suitable for intermittent demands, but it may also suit non-intermittent demands, thus providing great flexibility. The experimental analysis of two large datasets showed an excellent accuracy, which suggests that machine learning classifiers could be implemented in advanced inventory classification systems.     

Some aspects of price strategy

A firm's success, within a rapidly growing and dynamic market, depends upon its ability to respond to market demand and to react to competitive forces. A key factor determining success is the pricing policy employed by the firm. Product pricing, however, is not simple; supply and demand, as well as the interaction and reaction of competitors, must be taken into consideration. By simulating a competitive market environment, however, a firm should be able to evaluate different pricing strategies prior to employing a strategy in practice. The goal of this research was to propose a simulation model to serve this purpose. Particularly, the objective was to demonstrate that if an industry can be characterized as one in which cost as well as price decline with cumulative volume, a pricing policy leading to market dominance exists. A simulation model is desirable for evaluating the proper pricing strategy for achieving such a market position.     

Why are residential and school moves associated with poor school performance?

Most research on residential mobility has documented a clear pattern: Residential and school moves are associated with poor academic performance. Explanations for this relationship, however, remain speculative. Some researchers argue that moving affects social relationships that are important to academic achievement. But the association between moving and school performance may be spurious; the negative correlation may be a function of other characteristics of people who move often. We offer several conceptual and analytical refinements to these ideas, allowing us to produce more precise tests than past researchers. Using longitudinal data, we find that differences in achievement between movers and nonmovers are partially a result of declines in social relationships experienced by students who move. Most of the negative effect of moving, however, is due to preexisting differences between the two groups.     

Coming out to parents: perceptions of family relations, perceived resources, and identity expression as predictors of identity disclosure for gay and lesbian adolescents

This paper examines perceptions of family relations, identity expression, and pro-lesbian/gay resources as factors influencing coming out to parents. One hundred seventy-two adolescents responded to a survey originating from a clinical support group for lesbian and gay youth. Findings indicate that weak family relations significantly detract from coming out to parents indirectly through identity expression and perceived resources. Excluding the effects of family relations, adolescents perceiving supportive resources and expressing their lesbian/gay identity were more likely to come out to parents.     

A cross-national look at married women's earnings dependency

Using the Luxembourg Income Study data we examine married women's dependency on their husbands' earnings in nine Western industrialized countries: Australia, Belgium, Canada, Finland, Germany, the Netherlands, Norway, Sweden, and the United States. When we examine the level and degree of dependency, and the labor force participation of married women across countries, the nine countries fall into the three clusters delineated in Esping-Andersen's welfare states typology. But when we examine the determinants of the dependency within each country, the clustering disappears. Wives' dependency increases with age, the presence of young children, and the number of children. It is reduced when wives' labor force participation and education are high relative to their husbands' and in families that rely more on unearned sources of income. The similarity of patterns across countries suggests that gender differences in the work-family nexus are deeply entrenched in all countries and continue even in the face of very active social policy to minize their effects. This is a revised version of a paper presented at the annual meeting of the American Sociological Association, August 1995, Washington DC. Her current research focuses on gender inequality and parents' time allocation between work and family. She conducts research on various aspects of family demography, including household and family characteristics, co-resident grandparent families, cohabitation, and child care. With Suzanne Bianchi, she is completing a research monograph on trends in the American family. Her research focuses on gender, work, and family issues.     

Governing police practice: limits of the new accountability

The advent of public-sector managerialism has brought with it a new principle of police accountability in Western democracies such as Australia and Britain. The new accountability gives emphasis to managerial rather than legal or public-interest standards, favours external oversight combined with self-regulation rather than centralized control, and promotes risk management rather than rule enforcement. This article makes use of the experience of an Australian police force to show that the new accountability has not been successful in holding police accountable, while elements of the old accountability have re-emerged to dominate public debates. It is argued that in the area of police governance, the neo-liberal state does not necessarily pursue a coherent strategy of 'acting at a distance' (cf. Miller and Rose 1990), partly because of the inability of accountability technologies to deliver substantially the promised policy outcomes and partly because of the sensitivity of its political arm to the public's moral outrage against corruption (cf. Garland 1996).
