Elective single mothers are adult, unmarried women who intentionally become mothers. This study utilized longitudinal data about 17 Caucasian, elective single mothers and their children to identify fathers' roles in these families, and to understand children's views of their fathers. These single mothers and their children resided for the first six years of the children's lives in father-absent households. By age six, most of the children had ghost fathers, whom they had never met or knew little about. The data suggest that the father often becomes a family secret, and that children may blame themselves for their fathers' absence.  相似文献

This article examines the current trends of proliferation of commercial gaming, especially in the United States, in the context of the third wave of legalization of gambling that has been experienced since the founding of the nation. The author looks at the historic foundations of the spread of casino-style gambling, and notes the types of casino gaming that have led the way in the current expansion. He also points out why it is reasonable to expect that this wave too may come crashing down, as general acceptance of wide-spread casino gaming in America may indeed be short-lived.Gambling and the Law® is a registered trademark of I.

We describe a model to obtain strengths and rankings of players appearing in golf's Ryder Cup. Obtaining rankings is complicated because of two reasons. First, competitors do not compete on an equal number of occasions, with some competitors appearing too infrequently for their ranking to be estimated with any degree of certainty, and second, different competitors experience different levels of volatility in results. Our approach is to assume the competitor strengths are drawn from some common distribution. For small numbers of competitors, as is the case here, we fit the model using Monte-Carlo integration. Results suggest there is very little difference between the top performing players, though Scotland's Colin Montgomerie is estimated as the strongest Ryder Cup player.  相似文献

This article presents a framework for economic consequence analysis of terrorism countermeasures. It specifies major categories of direct and indirect costs, benefits, spillover effects, and transfer payments that must be estimated in a comprehensive assessment. It develops a spreadsheet tool for data collection, storage, and refinement, as well as estimation of the various components of the necessary economic accounts. It also illustrates the usefulness of the framework in the first assessment of the tradeoffs between enhanced security and changes in commercial activity in an urban area, with explicit attention to the role of spillover effects. The article also contributes a practical user interface to the model for emergency managers.  相似文献

Drawing on Canadian police data on homicide involving domestic dispute calls from 1960 to the present (n = 20), as well as on in‐depth interviews with police officers (n = 33) working in rural and remote communities, the authors reexamine the argument that police attendance at domestic disturbance calls can pose a special threat to officer safety. Although some scholarship suggests that purported risks have been overstated, the authors argue that location may be a critical factor in reducing or heightening not only risks to officers, but also to victims. Although intended as an exploratory work, situated within the context of cultural support for domestic violence in rural communities, the authors raise both interesting policy implications, as well as potential avenues for future research. En partant de données de la police canadienne sur les homicides impliquant des disputes familiales de 1960 à nos jours (n = 20), ainsi que sur des entrevues en profondeur avec des agents policiers (n = 33) travaillant dans des régions rurales et des communautés éloignées, les auteurs ré‐examinent l'argument voulant que les interventions policières lors d'appels liés à des problèmes domestiques posent un risque spécial pour les agents policiers. Même si certains spécialistes suggèrent que ces risques sont exagérés, les auteurs affirment que le lieu pourrait être un facteur important par rapport au niveau de risque pour les agents policiers, ainsi que les victimes. Même s'il s'agit d'une recherche exploratoire, se situant dans le contexte du soutient culturel de la violence domestique dans les communautés rurales, les auteurs s'intéressent à la fois aux implications en termes de gestion et aux directions possibles en termes de recherches futures.  相似文献

Pandemic influenza represents a serious threat not only to the population of the United States, but also to its economy. In this study, we analyze the total economic consequences of potential influenza outbreaks in the United States for four cases based on the distinctions between disease severity and the presence/absence of vaccinations. The analysis is based on data and parameters on influenza obtained from the Centers for Disease Control and the general literature. A state‐of‐the‐art economic impact modeling approach, computable general equilibrium, is applied to analyze a wide range of potential impacts stemming from the outbreaks. This study examines the economic impacts from changes in medical expenditures and workforce participation, and also takes into consideration different types of avoidance behavior and resilience actions not previously fully studied. Our results indicate that, in the absence of avoidance and resilience effects, a pandemic influenza outbreak could result in a loss in U.S. GDP of $25.4 billion, but that vaccination could reduce the losses to $19.9 billion. When behavioral and resilience factors are taken into account, a pandemic influenza outbreak could result in GDP losses of $45.3 billion without vaccination and $34.4 billion with vaccination. These results indicate the importance of including a broader set of causal factors to achieve more accurate estimates of the total economic impacts of not just pandemic influenza but biothreats in general. The results also highlight a number of actionable items that government policymakers and public health officials can use to help reduce potential economic losses from the outbreaks.  相似文献
