Causes of accidents and the time of day

Abstract

The relationship between accidents and the time of day is not entirely clear. Although there is considerable evidence that performance is poorest in the early morning hours compared to at all other times, the degree to which this is translated into accidents is not understood. In this study work-related fatal accidents were analysed to determine whether the causes of these accidents vary with time. The analysis used a classification and coding system devised to describe the wider circumstances of the causes of fatalities. In terms of absolute numbers, fatalities were most common in the late morning or early afternoon. When these results were expressed in terms of the estimated number of workers at work, the proportion of fatal accidents occurring at night was more than double that occurring during the day. Behavioural factors were the most common cause of fatalities at all times, but most common in the early hours of the morning. Further analysis of the nature of the behavioural involvement showed that errors in automatic processing (skill-based errors) were the most common types of error and did not vary much with time of day. Rule-based errors were most common during the day whereas knowledge-based errors occurred mainly in the afternoon and night shifts. These results cast some doubt on the assumption that there is a direct relationship between the previously observed variations in performance across time and the ultimate safety outcome.     

Migrant networks and the immigrant professional: An analysis of the role of weak ties

Weak ties, particularly those to potential employers, play a more important role than strong ties in the immigration of professionals to the United States. I operationalize network strength through the class of admission variable in the Immigration and Naturalization Service's public use data files,Immigrants Admitted to the United States, 1972–1992. I also examine the differential impact of legislative measures on the availability of strong versus weak ties for four groups of professionals: physicians, nurses, engineers and scientists. Not only do weak ties figure heavily on the immigration experiences of professionals, but those impacts affect women differently than men. Professional women rely more heavily on strong ties than on weak ties when compared with males in their respective professions, with the exception of nursing. These findings suggests a need for further study into the migration experiences of professionals as well as more research into how gendered networks develop among immigrant professionals and how those networks influence (either positively or negatively) immigrant adaptation to United States' society.     

A discussion of the differences in volunteering rates in the panel study of income dynamics,the current population survey,and independent sector volunteering studies

In this research note, I seek to explain differences in volunteering rates in three major volunteering studies—the Panel Study of Income Dynamics Philanthropy Module (known as the COPPS data), the Current Population Survey's volunteering supplement (CPS), and the Independent Sector's (IS) study, Giving and Volunteering in the United States. I compare each study in terms of survey methodology and volunteering questionnaire content. Then I discuss reasons for differences in the volunteering rates of these surveys based on methodology and questionnaire content.

State lotteries and compulsive gambling

The legalization of gambling, including state lotteries, has resulted in a dramatic increase of compulsive gambling. Not surprisingly, a new profile of compulsive gambler has emerged which differs significantly from the previous profile of white, middle aged, middle class male. This paper discusses public policy issues, lottery advertising, and legislative/lottery support given to address the problems of compulsive gambling.     

Bisexuals Making Out with Cyborgs: Politics, Pleasure, Con/fusion

This article considers the appeal of the figure of the cyborg for bisexuals, offering bisexual readings of both Donna Haraway's cyborg, and of the cyborg self created within text-based virtual reality. The writer argues that understanding bisexuality as part of a web of meanings and material realities can lead to a new political awareness, and suggests ways to make some of these connections. Through her analysis, she emphasises the role of technology in creating and developing contemporary bisexuality.
