Determinants of the probability and timing of commercial casino legalization in the United States

The adoption of lotteries by state governments has received significant attention in the economics literature, but the issue of casino adoption has been neglected by researchers. Casino gambling is a relatively new industry in the United States, outside Nevada and New Jersey. As of 2007, 11 states had established commercial casinos; several more states are considering legalization. We analyze the factors that determine a state’s decision to legalize commercial casinos, using data from 1985 to 2000, a period which covers the majority of states that have adopted commercial casinos. We use a tobit model to examine states’ fiscal conditions, political alignments, intrastate and interstate competitive environments, and demographic characteristics, which yields information on the probability and timing of adoptions. The results suggest a public choice explanation that casino legalization is due to state fiscal stress, to efforts to keep gambling revenues (and the concomitant gambling taxes) within the state, and to attract tourism or “export taxes.”     

Active ageing in employment: Its meaning and potential

This article focuses primarily on the recently emerged notion of “active ageing” and the policies necessary to turn it from a political slogan into an important mechanism in societal adjustment to population ageing. It begins by summarizing the main reasons for the growth of interest in active ageing. It goes on to describe the background to the concept of active ageing and its relationship to productive ageing. Then it outlines the basic principles on which policies on active ageing should be based and the key elements of a strategy to implement it. This is followed by a summary of the potential of active ageing to influence social protection expenditure. Finally the focus moves to the organizational level and the elements of an age management approach are presented. It is argued that a strategy of active ageing across the life course will enable ageing workers to exert a stronger influence over not only their later life careers but also their health and well-being. In addition to this personal empowerment active age management within organizations has the potential to improve efficiency and the optimum use of human capital. At the macro level active ageing can help to sustain or build up social protection systems. The main reference point for this article is Europe.     

The State in Environmental Management: The Ecological Dimension

A focus on 'modern' industrialized societies obscures both the great antiquity of the state and the powerful selective pressures that have led to the dominance of interstate competition, especially warfare. In pursuit of power, elites encouraged population growth and intensified the exploitation of the natural resource base, with progressively more severe ecological impacts. Modern technology has vastly amplified the problem. Though it makes possible sophisticated environmental management, that has been neglected for the demands of the military—industrial system. These ill-effects are reinforced by ignorance of ecology and inadequacy of traditional political thought. A major adaptive challenge faces modern states: to use their knowledge and resources for more humane, environmentally sensitive management and perhaps achieve a novel kind of steady state, or to renew emphasis on short-term competitive considerations.     

The computer and the law: coordinate analysis of skull shape and possible methods of postmortem identification.

Mechanisms accelerating or retarding the disintegration of soft tissues are briefly discussed, as well as the need to reconstruct the missing profile for postmortem identification purposes. The application of X-ray and computer-based analyses is discussed in the context of providing data to predict and reconstruct the most probable soft tissue profile of a dry skull. In addition, information from extensive studies of the facial bones and profiles of veterans has been applied to methods in forensic medicine of determining age, sex, and racial background of unknown subjects.     

Measuring the frequency occurrence of handwritten numeral characteristics—An expanded list

In the third of a series of studies and reports, the authors expand on the frequency occurrence proportions of various handwritten features. The first study culminated in the publication of “Measuring the Frequency Occurrence of Handwriting and Handprinting Characteristics.” That study was followed by “Measuring the Frequency Occurrence of Handwritten Numeral Characteristics.” The premise of this current and future follow‐up studies is to expand on the initial lists of information incrementally by expanding the number of features and the number of writers. This study expands on the list of numeral features. A total of 34 numeral features was selected by the authors as candidates for this study and tested through an attribute agreement analysis. Based on the results of the testing, 17 new features have been added to the list of proportions. The original 1410 handwritten numeral specimen forms were utilized and pared to 1024 to obtain a proper population sampling for the United States. Interdependency testing was conducted on 783 pairs of inter‐character numerals. A coefficient of correlation between ?0.2 and +0.2 was found in 534 (68.20%) of these pairs. As of this report, there are now a total of 42 numerals with measured frequencies of occurrence. This material has already borne fruit as the combined frequency of occurrence studies were explained during an unsuccessful exclusion hearing in court with an explanation as to how these studies support the reliability of forensic document examination.     

Value and Nature: Rethinking Capitalist Exploitation and Expansion

Value is central to the political economy of capitalism, but Marxian value theory has generally been abandoned when it comes to including nature in the analysis. An important exception is the recent work of Jason Moore, and in this paper an effort is made to fill several lacunae in Moore’s approach. I argue for a unified measure of labor-nature time and joint exploitation of surplus value, then explore the significance of that for capitalist growth via rising productivity and cheap inputs, as well as what these mean for geographic expansion in search of labor and resources. I finish on the classic note of the insatiable drive for capital accumulation and its implications for the fate of the earth.
