Role of workplace safety: a revisit of the relationship between job satisfaction and employment status

This study evaluated the relationship between employment status (i.e., part- and full-time) and job satisfaction, with the focus on the moderating roles of perceived injury risk and injury incidence. The results found that the level of job satisfaction for full-time workers was about the same regardless of the level of injury risk they perceived. In contrast, job satisfaction of part-time workers was significantly higher when they perceived low injury risk rather than high injury risk. The findings also supported the potential adverse impact of injury incidence and injury risk on job satisfaction for both part- and full-time workers. This study highlighted the importance of understanding both workplace safety and job satisfaction when attempting to understand the differences between part-time and full-time workers.     

Mixture structure analysis using the Akaike Information Criterion and the bootstrap

Given i.i.d. observations x1,x2,x3,...,xn drawn from a mixture of normal terms, one is often interested in determining the number of terms in the mixture and their defining parameters. Although the problem of determining the number of terms is intractable under the most general assumptions, there is hope of elucidating the mixture structure given appropriate caveats on the underlying mixture. This paper examines a new approach to this problem based on the use of Akaike Information Criterion (AIC) based pruning of data driven mixture models which are obtained from resampled data sets. Results of the application of this procedure to artificially generated data sets and a real world data set are provided.     

Policing Mental Disorder: Controversies, Myths and Realities

In this article the premises on which Section 136 of the Mental Health Act 1983 have been evaluated traditionally will be outlined and assessed using data from a recent empirical study. In examining the nature of police action in implementing this provision it is shown that police discretion and ability to act autonomously is constrained by the social context within which officers become involved in incidents and the external influences impinging on police decision making. It is suggested that legalism is inadequate both in accounting for the social realities of policing and relevant social policy implications. Instead, a social constructivist approach capable of accounting for wider influences on police action and mental health policy more generally is advocated as the basis on which to evaluate the future use of the provision.     

Using portfolios to stimulate critical thinking in social work education

Each generation of social work educators has grappled with the best way to teach students to become competent social workers. Critical thinking has become one goal in social work education. This paper is premised on the assumption that social work students can develop critical thinking abilities through portfolios. The theory behind the use of portfolios in social work education is a 'hand-in-glove fit' with critical thinking. In addition, portfolios are consonant with social work values of self-determination and individualisation. Portfolios are compendiums of purposefully selected student work to show that the objectives of a programme have been met. They are also useful as an alternative method of student evaluation. Portfolios and critical thinking are partners in educating students to become competent social workers.     

Black-White Differentials in Adult Homicide Mortality in the United States

Objective . This article examines individual level black-white differences in adult homicide mortality. Homicide is a major social problem and a central cause of preventable death in the United States. A homicide not only claims one life prematurely but can also devastate a family, friends, and a neighboring community. Methods . We link eight consecutive years of the National Health Interview Survey (1987–94) to the Multiple Cause of Death file through the National Death Index (1987–97), and use Cox proportional hazard models to examine the role of social factors in black-white homicide mortality in the United States. Results . We find that individual level sociodemographic characteristics—age, sex, marital status, education, employment status, and geographic factors—explain almost 35 percent of the racial differences in homicide mortality. Conclusions . These results demonstrate the contributions that National Center for Health Statistics data can make to criminological literature and reveal the mechanisms through which blacks experience higher homicide mortality than whites. Such illumination may lead to a reduction in the fourth leading preventable cause of death in the United States.     

Forecasting Mortality: A Parameterized Time Series Approach

This article links parameterized model mortality schedules with time series methods to develop forecasts of U.S. mortality to the year 2000. The use of model mortality schedules permits a relatively concise representation of the history of mortality by age and sex from 1900 to 1985, and the use of modern time series methods to extend this history forward to the end of this century allows for a flexible modeling of trend and the accommodation of changes in long-run mortality patterns. This pilot study demonstrates that the proposed procedure produces medium-range forecasts of mortality that meet the standard tests of accuracy in forecast evaluation and that are sensible when evaluated against the comparable forecasts produced by the Social Security Administration.     

Ethnicity as cognition

This article identifies an incipient and largely implicit cognitive turn in the study of ethnicity, and argues that it can be consolidated and extended by drawing on cognitive research in social psychology and anthropology. Cognitive perspectives provide resources for conceptualizing ethnicity, race, and nation as perspectives on the world rather than entities in the world, for treating ethnicity, race, and nationalism together rather than as separate subfields, and for re-specifying the old debate between primordialist and circumstantialist approaches.     

Some spatial aspects of poverty in the USA

The social problem of poverty in the USA. has important spatial dimensions. The great migration of poor persons from the agricultural South to the industrial North shaped the nation's process of urbanization in the period after World War II. Subsequent suburbanization in the nation's cities was profoundly influenced by this movement and, in turn, had important implications for the urban poor. Also, the changing structure of employment opportunities within urban areas has had direct effects on the nature of the poverty problem in terms of spatial segregation and the persistence of poverty in urban areas. This paper offers a survey of the spatial aspects of poverty in the USA. and relates the problem of poverty to the forces of change that have contributed to the spatial transformation of the US economy.     

Applicability of the Social Development Model to Urban Ethnic Minority Youth: Examining the Relationship between External Constraints,Family Socialization,and Problem Behaviors

The development of preventive interventions targeting adolescent problem behaviors requires a thorough understanding of risk and protective factors for such behaviors. However, few studies examine whether different cultural and ethnic groups share these factors. This study is an attempt to fill a gap in research by examining similarities and differences in risk factors across racial and ethnic groups. The social development model has shown promise in organizing predictors of problem behaviors. This article investigates whether a version of that model can be generalized to youth in different racial and ethnic groups (N=2,055, age range from 11 to 15), including African American (n=478), Asian Pacific Islander (API) American (n=491), multiracial (n=442), and European American (n=644) youth. The results demonstrate that common risk factors can be applied to adolescents, regardless of their race and ethnicity. The findings also demonstrate that there are racial and ethnic differences in the magnitudes of relationships among factors that affect problem behaviors. Further study is warranted to develop a better understanding of these differential magnitudes.     

MULTINATIONALS’ PRODUCTIVITY ADVANTAGE: SCALE OR TECHNOLOGY?

This study decomposes the productivity advantage of foreign multinationals into a technology and a scale effect and analyses the causal relationship between foreign ownership and these two components. This is done by analyzing the effects of an acquisition of a domestic establishment by a foreign multinational, using a combined propensity score matching and difference-in-differences estimation. The main results show that any positive impact of acquisition is predominantly due to changes in technical efficiency and not in scale and that the preacquisition productivity of the target plays a role in mediating the rate of technology transfer from the multinational.
