The management of the public lands in the United States has been shaped by the long-running conflict between environmental and utilitarian values. Recently, changing social expectations have increased demand for motorized recreational use and access. Critics contend such use of the public lands is a threat to their ecological health. Yet even as motorized use draws increased scrutiny and challenge, some commentators conclude that the battle is already over—and recreational users have won. This article focuses attention on the U.S. Forest Service and National Park Service and contends they are predisposed as institutions to favor demands for motorized recreational use and access. It concludes that what is needed is an explanation that seeks to place motorized recreational use in a historical and institutional context that offers a more complete understanding of why such users might be winning the battle.  相似文献

Working life continues to undergo rapid change. This change creates greater demand and sophistication and causes employees to experience more pressure, professionally and personally. Thus, absences from work due to sickness and injuries increase. In Sweden, this problem has become serious. This article argues that psychological empowerment and individual control are two key factors that minimize the many perils faced by the modern worker and those seeking to return to the work force through the vocational rehabilitation process. The findings show that a shift in ideology is needed. Specifically, there must be a shift from scientific management and Weberian bureaucracy towards organizational structures, routines, and cultures that support and increase individual worker psychological empowerment and control.  相似文献

The purpose of this paper is to trace the history of the social indicators or quality-of-life (QOL) research movement up to today, forecast future developments, and pave the way for future growth. Broadly speaking, we tried to review historical antecedents from the point of view of different disciplines, with specialists in each discipline preparing the basic text and co-authors helping to polish the material into a finished product. Briefly, we begin with an overview of the conceptual and philosophical foundations of our field of research. That is followed by a historical overview of the sociological roots of our field. In the third section, the main contributions from the discipline of economics are reviewed. Following that, the fourth section covers a historical overview of the literature on health-related quality of life is provided. Next, the history of QOL research from a marketing perspective is reviewed followed by a history from the perspectives of industrial/organizational psychology and management. Finally, we offer some forecasts for future QOL studies that are intended not only to predict what might happen, but to encourage, stimulate and motivate researchers to undertake new initiatives.  相似文献

Ecosystem processes along an urban-to-rural gradient   总被引:34,自引:9,他引:25  
In order to understand the effect of urban development on the functioning of forest ecosystems, during the past decade we have been studying red oak stands located on similar soil along an urban-rural gradient running from New York City ro rural Litchfield County, Connecticut. This paper summarizes the results of this work. Field measurements, controlled laboratory experiments, and reciprocal transplants documented soil pollution, soil hydrophobicity, litter decomposition rates, total soil carbon, potential nitrogen mineralization, nitrification, fungal biomass, and earthworm populations in forests along the 140 × 20 km study transect. The results revealed a complex urban-rural environmental gradient. The urban forests exhibit unique ecosystem structure and function in relation to the suburban and rural forest stands these are likely linked to stresses of the urban environment such as air pollution, which has also resulted in elevated levels of heavy metals in the soil, the positive effects of the heat island phenomenon, and the presence of earthworms. The data suggest a working model to guide mechanistic work on the ecology of forests along urban-to-rural gradients, and for comparison of different metropolitan areas.  相似文献

In contemporary societies, risk culture and risk profiling lead to the stigmatization of unhealthy behaviours as 'risky'. Risk denial theory refers to a cognitive way to deal with risky behaviours and can be considered as an updated variant of Sykes and Matza's neutralization theory. People neutralize the 'risky' label using specific techniques that must be added to those previously enlisted by Sykes and Matza. This paper introduces and discusses three techniques of risk denial: scapegoating, self-confidence and comparison between risks. As it is usually defined and studied as a 'risky behaviour', cannabis use provides a relevant example to illustrate these types of risk denial, thanks to various ethnographic studies (including Becker's seminal work on marijuana smokers) and quantitative French data from the 1999 European School Survey on Alcohol and Other Drugs (ESPAD). In order to deny the 'risky' label, cannabis users scapegoat 'hard drugs' users, they emphasize their own ability to control their consumption personally, or they compare cannabis and alcohol risks. The paper concludes with suggestions for further analyses of risk denial.  相似文献

The purpose of this study was to assess predictors of male-initiated psychological and physical partner abuse during the separation process prior to divorce among a sample of 80 divorced fathers who reported no physical violence during their marriages. The predictor variables examined were male gender-role identity, female-initiated divorces, dependence on one's former wife, depression, anxiety, and coparental conflict. Through ordinary least square (OLS) regression techniques, it was found that male gender-role identity was positively related to male-initiated psychological abuse during separation. Logistic regression analyses revealed that male-initiated psychological abuse, anxiety level, coparental conflict, and dependence on one's former spouse increased the odds of a man engaging in physical abuse. However, depression decreased the odds of separation physical abuse. The models predicting both male-initiated psychological abuse (F = 2.20, p < .05, R2 = .15) and physical violence during the separation process were significant (Model chi2 = 35.00, df= 7, p < .001).  相似文献
