A methodological critique of Cantor and Land's (1985) approach to the time series analysis of the crime–unemployment relationship is developed. Error correction models for U.S. homicide and robbery rates for the years 1946–1997 are presented to illustrate procedures for analyzing nonstationary time series data. The critique is followed by a discussion of methodological problems in work by Devine et al. (1988), Smith et al. (1992), and Britt (1994, 1997) that builds on Cantor and Land's approach.  相似文献

In this article we identify ‘new traditionalism’ as the discourse that dominates the historiography of the Indian environment. We challenge the new traditionalist equation of ‘forests’ and ‘nature’, their assertion that ‘traditional’ agriculture was ecologically balanced, and was practised by self‐contained communities, and their claims that women, forest dwellers and peasants were primarily the keepers of a special conservationist ethic. We next examine the new traditionalist claim that colonialism, modernity and development were exclusively responsible for the degradation of nature in India. Finally, we examine the new traditionalist interpretations of popular politics around environmental issues, specifically the Chipko movement. We make explicit the assumptions and political implications of new traditionalism and provide an alternative reading of Indian environmental history and politics.  相似文献

The Department of Homeland Security (DHS) applies a variation of the intelligence cycle – the process of planning, collecting, processing, analysis, and dissemination of information characteristic of intelligence agencies – to mitigate the risk of terrorist attack and respond to national security breaches. The intelligence cycle helps DHS encourage voluntary security measures, serve its customers, and avoid economic disruption, but the Department's program setbacks and failures illustrate the difficulty of applying the intelligence model to the needs of homeland security. The Department's particular means of producing intelligence and information challenge the conventional conception and definitions of the intelligence cycle.  相似文献

U.S. local governments in the 1980s were under increasing fiscal stress. The fiscal outlook is not particularly bright because of projected rapid growth of certain expenditures and the slow growth of most local revenue sources. Potentially major changes in fiscal responsibilities at the federal and state levels may call for local government fiscal reform in the future. This article uses a case study of Broome County, New York, to illustrate the difficulties local governments face and then suggests a series of revenue reforms that can enhance equity, efficiency, revenue productivity, and administrative simplicity.  相似文献

Using data from national surveys of jail and prison inmates conducted in 2002 and 2004, the authors found that male veterans in the age group that entered military service in the early years of the All Volunteer Force (AVF) were at greater risk of incarceration than nonveterans of similar age and ethnicity, whereas veterans who enlisted in later years of the AVF had less risk of incarceration than nonveterans. Although White veterans tend to have greater risk of incarceration than nonveteran Whites, Black and Hispanic veterans were at less risk than their nonveteran peers, although they are at greater risk than White veterans. These patterns are best explained by changes over time and in differential effects across racial/ethnic groups of recruiting practices, accession standards, and in civilian employment opportunities rather than combat trauma or other adverse experiences in the military. For example, reductions in the relative risk for incarceration of veterans during the AVF appear to generally result from increases in recruit qualifications and socioeconomic status due to greater military pay, improved skill in recruiting, and higher accession standards.  相似文献
