Tracking tuberculosis in the past: the use of genealogical evidence

A series of mutations of tuberculosis, present in the 1990s among elderly persons in the Province of Quebec (Canada), is interpreted as the outcome of a suite of three episodes of high mobility. The most recent is the rapid urbanization of the 1950s. In the 1840s exceptional mobility was a feature of frontier settlement and exploitation of timber. Unusual mobility in the 1750s and 1760s was associated with wartime conditions of the British conquest of Quebec and re-settlement of Acadian refugees. The scenario was developed from cartographic analysis (using geographic information systems), genealogies of the human hosts, and molecular genetics of the bacterium.     

Seismic Hazard Analysis Using Discrete Faults in Northwestern Pakistan: Part II – Results of Seismic Hazard Analysis

This article is the second of two companion articles that evaluate seismic hazard in northwestern (NW) Pakistan. Using the properties and characteristics of discrete faults in NW Pakistan described in the first article, probabilistic and deterministic seismic hazard analyses for 11 major cities in NW Pakistan were conducted. The results from both probabilistic and deterministic seismic hazard analyses exhibit good agreement. Median deterministic spectra compare favorably with uniform hazard spectra (UHS) for 475- or 975-year return periods, while the 84^th-percentile deterministic spectra compare favorably with the UHS for a 2475-year return period. Peak ground accelerations (PGAs) for 2475-year return periods exceed 1.0 g for the cities of Kaghan and Muzaffarabad, which are surrounded by major faults. The PGAs for a 475-year return period for these cities are approximately 0.6g — 3 to 4 times greater than estimates by previous studies using diffuse areal source zones. The PGAs for some cities located farther from faults (including Astor, Malakand, Mangla, Peshawar, and Talagang) are similar to those predicted using diffuse areal source zones. Seismic hazard maps for PGA and spectral accelerations at periods of 0.2 s and 1.0 s corresponding to three return period (2475, 975, and 475 years) were produced. Based on deaggregation results, a discussion of the conditional mean spectra for engineering applications is presented.     

THE POLITICAL ECONOMY OF WORKER PENSION FUNDS

Increasing concentration of economic power within the corporate sector, as well as the extent of corporate control by a few financial institutions such as commercial banks, have been subjects of intense scrutiny and debate in recent years. However, the role of private and public worker retirement trusts in providing power for institutional investors has not been adequately addressed. Pension fund assets, which were relatively inconsequential prior to 1960, and their investment in and share of total corporate equities minor, have grown to over $l410 billion by the end of 1977. In their analysis of and interest in public and private pension trusts, scholars, employers and even employees have tended to emphasize narrow economic issues such as investment performance. It is the central argument of this article that workers’ funds have become a major source of capital in the American economy, and as such have been used to help create and/or sustain practices that adversely impinge on workers themselves. It is argued that pension assets have contributed to: 1) the increasing power of financial institutions; 2) growth of corporate profits that only minimally benefit some pension plan participants; 3)capital shortages for 'socially useful’ investments; and 4)support of corporate enterprises that refuse basic worker demands including unionization itself. The study further suggests that the rapidly growing pension assets have the potential to serve‘the public interest’ as well as the needs of workers. Threat of withdrawal of funds from selected money managers and corporations, and utilization of share–holder voting rights to influence corporate policies can be potent weapons for organized labor. Since this is an exploratory analysis, the aim of the article is to gather, present and clarify basic information on worker pension trusts and to propose alternative avenues for future research in this critical area.     

‘The largest volunteer life saving corps in the world’: centering child caregiving in histories of U.S. human security through the Little Mothers’ League

Abstract

In this article, I explore the relationship between youth, security, and caregiving through a study of the U.S. Little Mothers’ Leagues, an initiative which began in New York City in 1910 with the aim of reducing infant mortality by training young girls to properly care for their infant siblings. Critical approaches to caregiving view security and insecurity as relational, drawing attention to contemporary power arrangements in the global caregiving industry and the contemporary crisis of care. However, in treating children as perpetual care recipients, it fails to provide a robust framework for understanding youth and children in historical and contemporary concerns related to human security. The history of the Little Mothers, largely children of European ‘non-native white’ immigrant families, illustrates the importance of children in securing population-wide well-being and the nation’s status in the global competition to reduce infant mortality. When set in contrast to the eugenics-inspired Mothercraft movement, the case reveals how children and youth become enlisted into projects of national human security, and how their ambiguity as caregivers – too young according to modern childhood, yet effective lifesavers – intersects with race and gender to further obscure their status as caregiving agents
