Gender and the residential telephone, 1890–1940: Technologies of sociability

Recent work on gender and technology debunks the claim that household technologies have liberated women from domestic work. The history of telephone use in North America suggests, however, that global conclusions about gender and consumer technologies may be misleading. Although marketed primarily as a business instrument and secondarily as an instrument to facilitate housework, the telephone was, in a sense, appropriated by women for social and personal ends. This paper explores the affinity of women for the telephone, how women in the half-century before World War II used the telephone, and why. It suggests that there is a class of technologies that women have exploited for their own, gender-linked, social and personal ends.     

Distinguishing the geographic levels and social dimensions of U.S. metropolitan segregation, 1960–2000

In this article, we assess trends in residential segregation in the United States from 1960 to 2000 along several dimensions of race and ethnicity, class, and life cycle and present a method for attributing segregation to nested geographic levels. We measured segregation for metropolitan America using the Theil index, which is additively decomposed into contributions of regional, metropolitan, center city-suburban, place, and tract segregation. This procedure distinguishes whether groups live apart because members cluster in different neighborhoods, communities, metropolitan areas, or regions. Substantively, we found that the segregation of blacks decreased considerably after 1960 largely because neighborhoods became more integrated, but the foreign born became more segregated largely because they concentrated in particular metropolitan areas. Class segregation increased between 1970 and 1990 mainly because the affluent increasingly clustered in specific metropolitan areas and in specific municipalities within metropolitan areas. The unmarried increasingly congregated in center cities. The main purpose of this article is to describe and illustrate this multilevel approach to studying segregation.     

Technology and Community: Historical Complexities*

As a comment on speculations that new electronic technologies will revolutionize community, this article points to three lessons drawn from historical studies on earlier technologies such as the telephone: (1) Effects are modest; (2) effects differ from one specific technology to another; and (3) the effects of any one technology can be contradictory.     

Accuracy and precision of the topological mapping procedure for estimating within-tree populations of bark beetles

Summary The accuracy and precision of the topological mapping procedure for estimating within-tree populations of bark beetles was investigated for a variety of different sampling conditions. Simulation techniques were used to define the mean and standard deviation of proportional errors encountered in estimation under different sampling intensities. The number of samples collected at a particular height and the vertical spacing between heights were varied. Information presented should aid in developing sampling plans for studies of bark beetle populations and will permit the reexamination and/or recovery of historical data sets on bark beetle populations.

Systemes demographiques et systemes supranationaux: La fecondite europeenne de 1952 a 1982

The analysis of fertility for 22 European countries and 8 Soviet Republics between 1952 and 1982 reveals different evolutionary models for socialist Eastern Europe and capitalist Western Europe. These models function as attractors (in the sense of fractal geometry) and suggest that demographic evolutions occur at a supranational level. Is it a matter of a bifurcation related to the geopolitical division established after 1945? Or should it rather be seen as a resurgence of the old historical division which cuts Europe into two parts along either side of a line from Trieste to Saint Petersberg?     

Community Literacy Resources and Home Literacy Practices Among Immigrant Latino Families

ABSTRACT

This paper reports relationships among communities, families, and Spanish-speaking children's language and literacy development in kindergarten and grade 1. Findings from a study of 35 communities show that communities with greater concentrations of Latinos are less likely to have printed materials, and available materials are more likely to be in Spanish. Communities with higher income and education levels have more literacy materials in English. Contrary to predictions, there are few associations among community literacy resources, frequency of children's home reading activities, and children's literacy achievement. This lack of association is due to within-community variation in home literacy practices and to schools' impact on home literacy. However, there are associations among community and family language characteristics and child literacy outcomes in Spanish and English, suggesting that at least in the early stages of literacy development, communities' influence on Spanish-speaking children's literacy development is through language-learning opportunities rather than literacy-learning opportunities per se.     

Occupational health and safety issues affecting young workers: a literature review

Many overview articles, reports, book chapters and literature reviews have examined the health and safety of young workers. These sources discuss the relationships between the work conditions of young workers and the various indicators of accidents and occupational diseases. Breslin et al. [12,13] conducted two literature reviews of quantitative studies to determine which factors best predicted work accidents and occupational disorders in young people. The present article proposes a review of young people's occupational health and safety (OHS) factors (e.g., demographic, individual, professional, organizational, temporal and operational factors) in both qualitative and quantitative studies. Five types of problems were analyzed in greater depth, namely MSD symptoms, respiratory, allergy and toxicological problems, mental health and well-being, alcohol and drug consumption, and fatigue. This review likewise examines related dimensions that allow us to adopt a more global perspective on this subject by considering such elements as young people's values, their knowledge and attitudes, safety practices in companies, the safe integration of young people, and rehabilitation. A total of 189 scientific articles were selected on the basis of certain criteria. These articles came from refereed OHS journals published between 1994 and 2005.     

What Defines Quality of Life? The Gap Between Public Policies and Locally Defined Indicators Among Residents of Kodagu, Karnataka (India)

Improving quality of life (QoL) is one of the main goals of many public policies. A useful tool to measure QoL needs to get a good balance between indicators guided by theories (top-down approach) and indicators defined by local people (bottom-up approach). However, QoL measurement tools often neglect to include elements that define the standard of living at local level. In this paper, we analyse the correspondence between human development index, as an indicator adopted by governments to assess QoL, and the elements defined by local people as important in their QoL, called here local means. Using a free-listing technique, we collected information from 114 individuals from Kodagu, Kartanataka (India), to capture local means defining QoL. We then compared local means with the indicators used by Human development report (HDR) of Karnataka, the main measurement tool of QoL in Kodagu. The list of local means included access to basic facilities and many issues related to agriculture and natural resources management as elements locally defining QoL. We also found that HDR does not capture the means defined by people as indicators of QoL. Our findings suggest an important gap between current QoL’s indicators considered by public policies and the means of QoL defined by people. Our study provides insights for a set of plausible local indicators useful to achieve a balance between top-down and bottom-up approaches for the local public policies.     

Predicted risk perception and risk-taking behavior: The case of impaired driving

Research suggests an association between risk perception and risk-taking behavior in a variety of contexts. There is empirical evidence that perceived risk is generally biased and that perception of risk influences behavior. Perception of risk can be endogenous. It is therefore more appropriate to instrument risk perception. This article studies the perception of the risks associated with impaired driving and the relation between predicted risk perception and driving behavior. We survey a sample of license-holders, half of whom are drivers with a past conviction for impaired driving, the other half or control group without such conviction. Predicted perceptual biases are shown to influence actual driving behavior.
