This study examines the attitudinal and demographic determinants of public preferences towards siting solid waste disposal facilities in the United States. Survey data is collected from a random sample of 400 individuals selected from the population of the State of Connecticut. A logit statistical model of public preferences towards siting is created. The results are consistent with previous research indicating the importance of variables reflective of self‐interest motivations, such as perceptions of costs and benefits, in influencing attitudes. However, it is also revealed that more longstanding values, in addition to narrowly defined personal costs and benefits, influence siting preferences. These include widely‐shared norms concerning need for the facility and the appropriate sphere of government influence. Effective, efficient and equitable siting policy must consider and respond to these additional public motivations.  相似文献

Distinct forms of reactions to sexual harassment were identified in the current study, and a classification scheme was developed based upon those reactions. One hundred forty two male and 100 female upper-division undergraduate management students and 44 working women read 18 randomly ordered scenarios, each of which depicted a woman being exposed to a different form of sexual harassment by a man. For each incident, the subjects were asked to write down what they themselves would do if they were in the woman's place. The resulting 5148 open-ended responses were systematically sorted into 10 classes of reaction types. In addition to assessing the reliability and validity of the classification scheme, the relative frequency of employment of the various classes was examined. Comparisons of the reactions of men and women students and comparisons of the reactions of working women and women students yielded few significant differences.  相似文献

The boundaryless career could be a bane or boon to people's experience of psychological success. This paper describes the contours of the boundaryless career and then looks at how workers will have to deal with aging over several career cycles, integrate diverse experiences into their identities, and come to terms with new types of employer-employee relationships. This introduces the idea of finding psychological success in one's life work, encompassing not only a job and an organization, but also work as a spouse, parent, community member, and as a self-developer.  相似文献

New forms of careers have received increased attention in contemporary organizational research. A prominent focus in this research has been whether and how, in an increasingly unpredictable career environment, individuals are taking responsibility for their own career development. The implication is that career is becoming less central to organizational management practices. At the same time there is evidence that organizational changes typically described in this literature (such as delayering the organization in a quest for flexibility) have had a negative impact on career progress, resulting in resistance to change. The implication here is that career concerns are more central to organizational management practices. This in‐depth qualitative case study examines whether individuals do in fact take more responsibility for their career development during times of organizational change. We also examine whether this does indeed mean that the organization takes less responsibility for career management. Our data indicate that individuals are, in fact, taking more responsibility for their own careers. At the same time we found that the organization in our case study also became more actively involved in career development and management. However, this active approach did not resemble traditional top‐down career management and development. To us, the pattern of organizational and individual career development actions appear to constitute a kind of ‘organizational dance,’ a highly interactive mutual influence process, in which both parties are at once the agent and the target of career influence. Strengths and limitations of the study are discussed, as are directions for future research. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Annual expenditures by the federal government in the United States for agricultural conservation programs increased about 80 percent with passage of the 2002 Farm Bill. However, environmental benefits of these programs have not been quantified. A national project is under way to estimate the effect of conservation practices on environmental resources. The watershed models intended for use in that project are focused on water quantity and quality and have minimal habitat assessment capability. Major impairments to aquatic ecosystems in many watersheds consist of physical habitat degradation, not water quality, suggesting that current models for this national initiative do not address one of the most significant aspects of aquatic ecosystem degradation. Currently used models contain some components relevant to aquatic habitat, and this paper describes specific components that should be added to allow rudimentary stream habitat quality assessments. At least six types of variables could be examined for ecological impact: land use, streamflow, water temperature, streambed material type, large woody debris, and hydraulic conditions at base flow. All of these variables are influenced by the presence, location, and quality of buffers. Generation of stream corridor ecological or habitat quality indices might contribute to assessments of the success or failure of conservation programs. Additional research is needed to refine procedures for combining specific measures of stream habitat into ecologically meaningful indices.  相似文献

We surveyed three distinct samples of employees (Ns of 238, 102, and 981) in order to examine relations among various types of underemployment, job satisfaction, organizational commitment, and turnover intentions. Each dimension of underemployment is explored as a case of poor person‐job fit, and the fit literature is used to produce hypotheses about these relations. We also developed and validated the 9‐item Scale of Perceived Overqualification (SPOQ) to tap employee perceptions of surplus education, experience, and KSAs (knowledge, skills, and abilities). In general, perceptions of underemployment were associated with poor job satisfaction, particularly for facets with a direct causal relationship with the specific dimension of underemployment, such as overqualification and satisfaction with work. Perceived overqualification was also related to lower affective commitment, and higher intentions to turnover. For part‐time work, negative attitudes were only found when employees expressed a preference for full‐time work; a similar trend was not found for temporary workers, however. Implications for theory, research, and practice are delineated. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

The major purpose of this paper is to explore the potential value of benefit–cost evaluation for stormwater quality management decisions at a local level. A preliminary benefit–cost analysis (BCA) screening method is used for maximum extent practicable (MEP) analysis, identifying promising management practices, and identifying societal and economic tradeoffs for local stormwater problems. Ballona Creek, a major urban storm drain in Los Angeles, California, USA, is used to illustrate the practicality of the benefit–cost evaluation. The Ballona Creek example demonstrates the economic limits of stormwater management in an urban region and attests to the value of coordinated basinwide management compared to uncoordinated management by individual landowners. Evaluation results suggest that in urban areas, the benefit of stormwater quality improvements might be far greater if accompanied by comprehensive redesign of drainage networks and neighboring land uses. In this case, benefit–cost analysis is found to be useful for evaluating and understanding stormwater management alternatives despite the uncertainties in characterizing stormwater quality and the effects of stormwater management on improving receiving water quality.  相似文献

This paper presents a ranked set sample allocation procedure that is optimal for a number of nonparametric test procedures. We define a function that measures the amount of information provided by each observation given the actual joint ranking of all the units in a set. The optimal ranked set sample allocates order statistics by maximizing this information function. This paper shows that the optimal allocation of order statistics in a ranked set sample is determined by the location of the mode(s) of the underlying distribution. For unimodal, symmetric distributions, optimal allocation always quantifies the middle observation(s). If the underlying distribution with cdf F is a multi-modal distribution with modes , then the optimal allocation procedure quantifies observations at in a set of size m. We provide similar results for unimodal, asymmetric distributions. We also propose a new sign test which considers the relative positions of the quantified observations from the same cycle in a ranked set sample. The proposed sign test provides improvement in the Pitman efficiency over the ranked set sample sign test of Hettmansperger (1995). It is shown that the information optimal allocation procedure induced by Pitman efficiency is equivalent to the optimal allocation procedure induced by the information criteria. We show that the finite sample distribution of the proposed test based on this optimal design is binomial.  相似文献

OBJECTIVE: A critical review of the existing evaluation studies on the Drug Evaluation and Classification (DEC) program was conducted to determine the validity and accuracy of the technique for identifying drivers under the influence of drugs. METHODS: Studies were divided into two categories--laboratory studies and field (i.e., enforcement) studies. A classification process was devised using common criteria based on the toxicology findings (i.e., drug positive or drug negative) and the opinion of the police officer who assessed the driver (i.e., drug positive or drug negative). A series of standard measures (Sensitivity, Specificity, False Alarm Rate, Miss Rate, Corroboration, and Accuracy) were calculated for each to assess the effectiveness of the DEC program. RESULTS: Laboratory studies do not provide overwhelming support for the accuracy with which officers trained in the DEC program can detect and identify the particular class(es) of drug involved based on psychophysical assessment alone. The detection and identification of the relatively low levels of drugs administered were typically better than chance but many cases were missed. The fact that some drugs were detected with greater accuracy than others suggests that the effects of these substances were more prominently manifested in the symptomology assessed by the DEC procedure. Although field enforcement studies are not as scientifically rigorous as laboratory studies, DEC assessments in an enforcement context have the benefit of information obtained from the arresting officer and from interviews with the suspect. In addition, the drug doses consumed by users are typically much higher than those permitted in controlled laboratory studies. In general, officers trained in the DEC program are able to identify persons under the influence of drugs and to specify the drug class responsible with a degree of accuracy that not only exceeds chance, but in some cases reaches a very high level. CONCLUSIONS: There remains room for improvement in the DEC program. As further research becomes available, either from laboratory or field investigations or both, it needs to be incorporated into the program to enhance its validity and accuracy.  相似文献
