Estimates Of U.S. Multiple Cause Life Tables

Cause elimination life tables estimated from multiple cause of death data for four race/sex groups are presented for the U.S. population in 1969. These “multiple cause” life tables are then compared to cause elimination life tables where the mortality risk eliminated is that of the cause of death only in its occurrence as the underlying cause of death. An evaluation is made of the possible effects of the multiple cause data on our perception of the relative importance of the major causes of death. The reconceptualization of mortality risks made possible by the multiple cause of death data is also assessed in terms of its providing further insight into the “Taeuber paradox.”     

A test of equilibrium theory: Effects of topic intimacy and proximity on verbal and nonverbal behavior in pairs of friends and strangers

This experiment examined verbal and nonverbal behavior by pairs of female friends and strangers as they discussed either intimate or nonintimate topics at face-to-face distances of approximately 2.5 or 4.5 feet. On the basis of equilibrium theory and Altman and Taylor's (1973) theory about interpersonal exchange, strangers were expected to react to intimate topics or close proximity or both with discomfort and decreased affiliative behavior (facial regard, gesturing, speech). Friends were expected to show increased affiliative behavior. Results indicated that both strangers and friends showed signs of discomfort and low levels of affiliative behavior while discussing intimate topics, i.e.compensation. Discomfort with intimate topics and compensation decreased over time, indicatingadaptation. This finding suggests that compensation for intimate topics may occur only during the initial phases of an encounter.

Materializing Strategy in Mundane Tools: the Key to Coupling Global Strategy and Local Strategy Practice?

While much of the literature on strategy and strategy as practice (SaP) focuses on traditional strategic tools, technologies and discursive practices of managers, this paper extends the understanding of strategic change implementation by proposing that mundane material tools, understood as text, translate global strategic discourse in ways that make sense to workers and orchestrate successful global strategy implementation at the local level. Based on a rich case study within one branch of a national bank, this paper demonstrates how a middle manager's materializing practices developed local strategy practice while simultaneously transforming work and producing strategic figures or indicators that satisfied senior management's global strategic change objectives. The contributions of this paper are threefold: (i) it advances the understanding of the multimodality of materiality by identifying the influence of three types of mundane tools produced locally by a middle manager as he performed his sense of the senior managers’ strategic discourse; (ii) it reveals how these three types of physical texts materialized the manager's sense of this discourse, facilitating frontline workers’ engagement and coupling materiality and orality in a coherent way that allowed workers to embody the company's global strategy in their ‘sayings and doings’; and (iii) it highlights the importance of managers’ ability to materialize a strategic discourse.     

“I’m not homeless,I’m houseless”: identifying as homeless and associations with service utilization among Los Angeles homeless young people

Little is known about homeless young people’s identification of being homeless and how that identity may or may not be associated with service utilization. This study of 444 homeless young people attending Los Angeles area drop-in centers explores the associations of demographic characteristics, homelessness characteristics, negative lifetime experiences, mental health symptoms, technology use, and past month service utilization with identifying as homeless. Fifty-two percent of the sample identified as being homeless. Being Black, a current traveler, and history of injection drug use were all significantly associated with a decreased likelihood in identifying as homeless. However, having fair/poor health, accessing shelter services, and reporting one’s own substance use as a reason for homelessness were all significantly associated with identifying as homeless. There are important service implications for reaching young people who are in need of services but may not identify with the target population label of homeless.     

Early Modern Antwerp: The First “World City”?

It is problematic to think of globalization as a new phenomenon and to believe that the phenomenon of a world city, embedded in the global division of labor, is a 20^th century novelty. World city literature in sociology often emphasizes, if not assumes, the relatively recent emergence of world cities in the “new” international division of labor. Sixteenth century Antwerp, however, was the first world city of an expanding capitalist world economy. Understanding this phenomenon and its decline can raise important questions about the modus operandi of subsequent world cities.     

Aldrin and Dieldrin: A Reevaluation of the Cancer and Noncancer Dose‐Response Assessments

The dose‐response analyses of cancer and noncancer health effects of aldrin and dieldrin were evaluated using current methodology, including benchmark dose analysis and the current U.S. Environmental Protection Agency (U.S. EPA) guidance on body weight scaling and uncertainty factors. A literature review was performed to determine the most appropriate adverse effect endpoints. Using current methodology and information, the estimated reference dose values were 0.0001 and 0.00008 mg/kg‐day for aldrin and dieldrin, respectively. The estimated cancer slope factors for aldrin and dieldrin were 3.4 and 7.0 (mg/kg‐day)^?1, respectively (i.e., about 5‐ and 2.3‐fold lower risk than the 1987 U.S. EPA assessments). Because aldrin and dieldrin are no longer used as pesticides in the United States, they are presumed to be a low priority for additional review by the U.S. EPA. However, because they are persistent and still detected in environmental samples, quantitative risk assessments based on the best available methods are required. Recent epidemiologic studies do not demonstrate a causal association between aldrin and dieldrin and human cancer risk. The proposed reevaluations suggest that these two compounds pose a lower human health risk than currently reported by the U.S. EPA.     

Is the Pro-Poor Premium Exemption Policy of Ghana’s NHIS Reducing Disparities Among the Elderly?

Under the act that established the National Health Insurance Scheme (NHIS), persons 70 years of age or above are automatically enrolled in the scheme and therefore can access health services free at the point of use. This suggests that the elderly who are unable to afford the premiums of private health insurance can enrol in the NHIS thereby eliminating the possibility of disparities in health insurance coverage. Notwithstanding, few studies have examined health insurance coverage among the elderly in Ghana. The lack of studies on the elderly in Ghana may be due to limited data on this important demographic group. Using data from the Study on Global Ageing and Health and applying logit models, this paper investigates whether the pro-poor exemption policy is eliminating disparities among the elderly aged 70 years and older. The results show that disparities in insurance coverage among the elderly are based on respondents’ socio-economic circumstances, mainly their wealth status. The study underscores the need for eliminating health access disparities among the elderly and suggests that the current premium exemptions alone may not be the solution to eliminating disparities in health insurance coverage among the elderly.
