The Risks of "Putting the Numbers in Context": A Cautionary Tale

Despite the warnings of risk communication specialists, members of the technical community often urge that technological risks should be "put in context" by comparisons against risks that are more familiar. Little quantitative evidence is available on the actual behavioral consequences of such risk comparison efforts. In the present study, subjects were presented with two types of information about a hazardous waste incinerator–a simplified statistical summary and a comparison of incinerator risks against the risks of smoking. Statistical information led to a modest increase in the reported willingness to vote in favor of the incinerator in a community referendum, but the comparison against cigarettes led to a slight decrease in support; the difference between the two messages is statistically significant ( p <.001). In combination with other results, this study's findings suggest that an implicit assumption of risk comparisons is in error: Opposition to controversial technologies may have little to do with citizens' levels of information about technology, having more to do with citizens' levels of trust in governmental and industrial actors.     

Child welfare involvement among children in homeless families

An analysis of 8251 homeless children in New York City found that 18% of them received child welfare services over the five-year period following their first shelter admission, and an additional 6% had a history of having received such services before their first shelter admission. Recurrent use of public shelters, exposure to domestic violence, older age at first episode of homelessness, and larger number of children in a household were associated with an increased risk of child welfare involvement. The high rate of crossover between homelessness and the child welfare system suggests the need for service coordination for children in homeless families.     

The Economic Impacts of a Terrorist Attack on the U.S. Commercial Aviation System

We use data on air passenger travel expenditures per passenger as well as statistical analysis of the air traffic lost for the two-year aftermath of the September 11, 2001, attacks to estimate direct demand losses for air transportation services. These are used along with a national input-output model to assess the full costs of these losses. Depending on assumptions made, the full losses to the U.S. economy were between $214.3 and $420.5 billion. These estimates are similar to those from other studies of such an event, and suggest that the high costs of effective countermeasures may be justified.     

A comprehensive work injury prevention program with clerical and office workers: phase I

The risk for the development of musculoskeletal disorders and associated conditions in clerical and office workers is well documented. The majority of work injury prevention programs for this population were single-faceted (education, workstation redesign, or task modification) and yielded both positive and negative findings. This pilot study was conducted with 16 full-time clerical and office workers at a small private college. In a randomized control trial, the intervention group received four hours of individualized training through a multi-faceted injury prevention program. Between group differences in musculoskeletal symptom frequency and intensity and perceived stress and energy levels existed, although were statistically insignificant. There was a statistically significant decrease in Lower Back ache/pain from pre to post measures for the intervention group.     

Sex-role attitudes and employment status as predictors of perceived life satisfaction among married women in Korea

The focus of this exploratory study is on reexamining the relationship between sex role attitudes and the employment status of married women in Korea, and exploring the nature and extent of women's sex role attitudes and employment status on their life satisfaction (marriage, family, work). Multicluster sampling was used to select 418 women from the city of Seoul. The Attitudes toward Women Scale (AWS) (Spence and Helmreich) was used to measure the concept of sex role attitudes. Life satisfaction was measured by 3 questions: ALLSAT, a general feeling; IGA for the general effect based on Osgood's semantic differential scales; and work status and voluntariness. Background characteristics are given. The results revealed that there was an independent relationship between sex role attitudes and employment status. Based on willingness to work groups (4), those who worked involuntarily had the most conservative sex role attitudes, and those involuntarily nonworking had the most liberal attitudes. When education background was controlled for, there were no significant differences between working and nonworking women and sex role attitudes. There was little relationship observed between sex role attitudes and overall satisfaction. When controlling for employment status, however, sex role attitudes and the relationship to work satisfaction was statistically significant among fulltime housewives, who had conservative attitudes. In fact, fulltime housewives reported greater satisfaction with their role as homemaker than those with liberal sex role attitudes. Women's attitudes and their actual roles has a greater influence on women's life satisfaction than sex role attitudes. Overall, working women are more satisfied with work and overall life than are nonworking women, when the mean satisfaction scored all 6 indicators are used in a 1 way analysis of variance. There were no significant differences in satisfaction with marriage or family life between working and nonworking women. When the intervening variable willingness to work is introduced, this plus employment status affects life satisfaction. The discrepancy between women's sex role attitudes and their work status produces the greatest dissatisfaction. The multiple regression of background variables affecting sex role attitudes shows that parent's encouragement for a woman to work has the strongest effect. Educational attainment has a positive effect on sex role attitudes, and among less well education has a negative effect and positive effect among those well educated, Husband's income is significantly higher than that for working women. Another model expressing reciprocal relations between marriage, family and work satisfaction was generated. Improvements are suggested for future research.     

Robust difference-based outlier detection

Abstract

In this paper, we propose an outlier-detection approach that uses the properties of an intercept estimator in a difference-based regression model (DBRM) that we first introduce. This DBRM uses multiple linear regression, and invented it to detect outliers in a multiple linear regression. Our outlier-detection approach uses only the intercept; it does not require estimates for the other parameters in the DBRM. In this paper, we first employed a difference-based intercept estimator to study the outlier-detection problem in a multiple regression model. We compared our approach with several existing methods in a simulation study and the results suggest that our approach outperformed the others. We also demonstrated the advantage of our approach using a real data application. Our approach can extend to nonparametric regression models for outliers detection.     

Innovative approach for the treatment of cumulative trauma disorders

Cumulative Trauma Disorders (CTDs) is the latest four-letter word for employees and employers. The purpose of this pilot study was to test the efficacy and cost effectiveness of ASTM, previously executed with Division I college athletes, in a work-related population. ASTM uses specially designed instruments to assist clinicians in rapid localization and effective treatment of soft tissue fibrosis/scar tissue. The protocol includes a flexibility and functional program that helps the worker adapt to the demands of the job. Physical and occupational therapists in both an outpatient clinic, and an industrial on-site setting, utilized ASTM. ASTM was considered successful, with symptoms resolved in over 70 percent of the patients. ASTM demonstrated impressive results in both settings and decreased medical and non-medical expenditures.     

Generational affinities and discourses of difference: a case study of highly skilled information technology workers

Sociologists theorizing the concept of 'generation' have traditionally looked to birth cohorts sharing major social upheavals such as war or decolonization to explain issues of generational solidarity and identity affiliation. More recently, theorists have drawn attention to the cultural elements where generations are thought to be formed through affinities with music or other types of popular culture during the 'coming of age' stage of life. In this paper, we ask whether developments in computer technology, which have both productive and cultural components, provide a basis for generational formation and identity and whether generational discourse is invoked to create cultures of difference in the workplace. Qualitative data from a sample of Information Technology workers show that these professionals mobilize 'generational' discourse and draw upon notions of 'generational affinity' with computing technology (e.g. the fact that people of different ages were immersed to varying degrees in different computing technologies) in explaining the youthful profile of IT workers and employees' differing levels of technological expertise.     

“I Can Provide for My Children”: Korean Immigrant Women’s Changing Perspectives on Work Outside the Home

Whether immigrant women’s introduction to paid labor empowers them with greater autonomy or exacerbates their oppression has been debated variously in the scholarship on gender and migration. In this paper, the author examines Korean immigrant women’s perspectives on work outside the home after migration. Based on in-depth interview data, the paper emphasizes Korean women’s own interpretations of work and motherhood, and highlights the ways in which they define and redefine work in relation to other aspects of their post-migration experiences. The analysis finds that income producing work is not empowering in and of itself, but contingent upon other post-migration challenges such as economic downward mobility and women’s changed roles as working mothers. Furthermore, women’s perception of work fluctuates over time. The findings suggest that paid work should not be simply interpreted as an empowering change, but the linkage between work and other aspects of immigrant women’s post-migration realities needs to be more closely examined.
