Abstract The persistence of ethnic settlement in rural regions of the United States is well documented. Yet, there has been little discussion of techniques which allow the identification of the geographic extent and concentration of distinctive ethnic populations. Amish-Mennonite settlement constitutes a unique component of the rural landscape. A wide range of visual clues alert the observer to their presence, but without painstaking field surveys it is difficult to establish their geographic extent. This paper examines four approaches to the identification of Amish-Mennonite settlement. These are county-based population data on religious affiliation, the location of Amish church districts and Mennonite churches, topographic maps, and surnames and cadastral maps. Topographic maps proved unsuitable, but each of the other approaches produced reasonable approximations of the areal extent of Amish-Mennonite settlement. Surnames and cadastral maps present good possibilities for the identification of other ethnic populations in rural regions. 相似文献

Transportation of hazardous materials, and particularly radioactive wastes, on public highways has become an important risk management issue. The unfavorability of public attitudes regarding hazardous and nuclear wastes signals the potential for strong public opposition to programs for transporting these materials. This paper presents the results of a survey conducted to assess public reactions to a long-term nuclear waste transport program planned to follow a route through a portion of rural Oregon. The survey assessed a number of key risk perception issues, including perceived health and safety risks of nuclear waste transport, relative risks of transport vs. storage at an existing site, trust in state officials, and satisfaction with life in communities along the transport route. The survey identified a number of attitudes and concerns that need to be understood and considered by those in charge of designing and implementing the waste-transportation program. 相似文献

The relation of four hypothesized sources of self-efficacy information to high school students' math self-efficacy was explored. Results indicated that (a) of the hypothesized sources, prior performance was the most efficient predictor of self-efficacy; (b) global academic self-concept did not explain unique self-efficacy variation beyond prior performance; and (c) the effect of self-efficacy on the perceived utility of math to future life and work plans was mediated by students' math/science interests. 相似文献

Reductions in sleep are concomitant with night shift work. Data are presented showing that these robust differences in sleep are even present in experienced permanent night shift workers who most prefer to work nights. A model is presented which relates these reductions to chronic sleep deprivation. This, in turn, may be associated with performance decrements, and lead to accidents and illness. Better work schedule selection, worker training programs, and preventive medical action are unproven but promising approaches to overturning this model. 相似文献

Today it is common for business people to refer to themselves as pragmatists. There is, however, at least one significant difference between business pragmatism and traditional philosophical pragmatism: the attitude towards ethics. In this paper we discuss several approaches business pragmatists have taken toward ethics in business. We then describe the approach taken by one philosophical pragmatist, William James. We conclude that, pragmatically speaking, philosophical pragmatism is the superior view. 相似文献

Two parallel self-administered surveys were distributed at three conferences of Gamblers Anonymous. One survey was for members of Gamblers Anonymous and the other was for members of GamAnon. Approximately 500 respondents completed the surveys, with 215 having completed the questionnaire for the spouse. This article is a report of some of the data from the spouse's survey. This survey focused on two time periods of the spouse's life — during the desperation phase of the gambler's illness (Custer, 1982) and the phase following a period of abstinence from gambling. Specific areas covered in this report focus on the psychosomatic problems and emotional difficulties encountered by the spouse, marital and familial estrangement, financial management, and the need for mental health services. It is anticipated that some of these needs can be met through training or therapy sessions in professional gambling treatment centers and at Gamblers Anonymous conferences.The work on this spouse survey represents a collective effort to enhance the understanding of the relationship between the pathological gambler and the spouse during the desperation phase of the illness and during recovery. Dr. Lorenz developed and implemented the survey. Yaffee organized the data processing, statistical programming, and analysis of the survey. For dedicated and outstanding assistance, special thanks must be given to our senior research assistants, who prepared the codebook and program for this spouse survey: Maria Ycasiano, Leslav Giermanski, Roger Meier, Raisa Rot and Steven Rubenstein. Thanks must also be given to Norberto Colon, Paula Diamond, Edwin Castro, Abdul Beydoun, and Fallan Rhim for their valuable assistance in entering, checking, and cleaning the data prior to analysis. Appreciation for the program written by Joseph Lautner, to check for misalignments in the data file, and the assistance provided by Deborah Becker on this project, is also gratefully acknowledged. To Dr. Thomas Wesselkamper, Chairman of the Hunter College Science Department, for permission to run this project, and all of the aforementioned research assistants, the authors express their sincere gratitude. 相似文献

Proxy fights have received comparatively little attention relative to the more popular methods for corporate control transfer: merger and tender offers. This paper presents an analytic model of the proxy contest as a cooperative game with four players: management, passive shareholders, insurgent shareholders and a trust fund. The power of the players and the effectiveness of certain managerial actions is discussed. 相似文献

An anonymous 37-item Health Survey was administered to 844 randomly selected ninth- to twelfth-grade students in four Southern California public high schools. Systematic information was gathered about their general health, quality of life, school and work adjustment, involvement with a range of potentially addictive substances and activities, and indications of psychosocial maladjustment, including difficulties with the law and suicide attempts. A series of self-ratings of students who characterized one or both of their parents as having a compulsive gambling problem (N=52) were contrasted with those of their classmates who reported no gambling problem among their parents (N=792). Findings have been grouped into three major areas: (a) comparative levels and reported effects of involvement with health-threatening behaviors (i.e., smoking, drinking, drug use, overeating, and gambling); (b) comparative incidence of psychosocial risk indicators (i.e., broken home, unhappy childhood and teenage years, legal action pending, overall quality of youth rated as poor); and (c) comparative incidence of dysphoria, school and work problems, and suicide attempts. Across each of these areas children of parents said to gamble excessively were found to be at consistently greater risk than their classmates who did not describe their parents as having a problem with compulsive gambling. These findings strongly suggest that without early and competent intervention, children of parents who gamble excessively: (a) will be seriously disadvantaged when attempting to solve their present adolescent and future adult problems of living; and (b) as a consequence are, themselves, high-risk candidates for developing one or another form of dysfunctional adjustment, including an addictive pattern of behavior. 相似文献
