This report presents the current status of a series of studies oriented toward the assessment of perceived life quality. The conceptual model proposes that a person's overall sense of life quality is understandable as a combination of affective responses to life ‘domains’, which are of two types-role situations and values. Over 100 items used to measure a wide variety of domains and 28 items assessing perceived overall life quality are presented. Various subsets of these items were used in interviews with several representative samples of American adults. Based on these data the domain items were grouped into a smaller number of semi-independent clusters which were internally stable across 10 different subgroups of the respondents and whose interrelationships were highly replicable in independent national samples. A series of analyses, some replicated in more than one survey showed: (1) an additive combination of 12 selected domains explained 50–60% of the variance in an index of overall life quality, (2) neither other domains nor several social characteristic variables contributed additional explanatory power, (3) this level of explanation was achieved in each of 22 subgroups of the population, and (4) additive combinations of domains worked as well as more complicated combinations. 相似文献

This study examines substance use severity, levels of social and health service utilization, and the impact of service utilization on treatment outcomes for sexual minorities versus non-minorities. The sample included 3,094 clients from the National Treatment Improvement Evaluation Study (NTIES). Substance use severity among sexual minorities and non-sexual minorities was similar at treatment entry and at 12 months post-discharge. Differences in social and health service utilization were significant for substance abuse counseling and health services. Significant interactions between sexuality and access services and sexuality and mental health services were also found. Practice and research implications are discussed. 相似文献

In this paper we examine the management of human-double-crested cormorant conflicts in urban nature areas using the Leslie
Street Spit in Toronto, Ontario as our focal study area. We examine the management perspectives of various stakeholders and
how they shift over time in response to site ecology and stakeholder input. We categorize management perspectives on a spectrum
from complete human domination to near absence of human intention. Two broad management categories emerge from this framework:
interventionist and laissez-faire. Interventionists recognized need for management of cormorants, laissez-faire argued for
no management of a cormorant colony that has deforested 24% of the site through their nesting activities. We conclude that
for urban nature areas, particularly those with a unique, rare, or contentious ecology, a hands-off, laissez-faire management
approach is not conducive to improving human-nature relations. Rather, for urban nature sites nature management must promote
a respectable balance between human and non-human life, for the long-term benefit of both. 相似文献

This investigation begins from the hypothesis that social indicators of perceived well-being — e.g., people's assessment of their own life quality — will, like other attudes, reflect two basic types of influences: affect and cognition. In addition, the indicators were expected to include two other components: unique variance (mainly random measurement error) and correlated measurement error. These ideas are investigated using a structural modeling approach applied to 23 assessments of life-as-a-whole from a national survey of Americans (N=1072) and/or a survey of urban residents in England (N=932). In both sets of data, models that included affective and cognitive factors fit significantly better than more restricted models. Furthermore, as expected, measures of (a) ‘happiness’, ‘fun’, and ‘enjoyment’ tended to be relatively more loaded with affect than were measures of (b) ‘satisfaction’, ‘success’, and ‘meeting needs’; and (c) measures designed to tap both affect and cognition tended to fall between the first two groups. In addition, the results suggest that measures employing relatively many scale points and direct assessments yield more valid indicators of people's evaluations of life-as-a-whole than do measures based on three-point scales or on explicit comparisons with other times or groups. These results contribute to basic knowledge about the nature of life quality assessments, help to explain some previously puzzling relationships with demographic factors such as age and education, and may be useful to designers of future studies of perceived well-being. 相似文献

A number of subjective well-being scales were compared and evaluated. The Satisfaction With Life Scale emerged as a good measure of general life satisfaction and the Affective Intensity Measure appeared to adequately assess the characteristic level of emotional intensity. Most other scales seemed to reflect both life satisfaction and duration of positive versus negative affect. Of the single item measures, those created by Fordyce were the strongest, whereas for the multi-item scales, several performed at adequate levels. The widely used Bradburn scales showed several undesirable psychometric properties and alternative scales are suggested. 相似文献

Background
Substance use during pregnancy is a major public health concern, stemming from potential physical and psychosocial harms to both the mother and child.Purpose
To understand women’s experiences using substances during pregnancy and the reasons that women continue and/or discontinue using substances.Methods
Focus groups were conducted with women who attended an early intervention program for pregnant or parenting women with substance use issues.Results
Women identified that external and internal stressors, feelings of guilt and low-self efficacy, and a lack of understanding of the scientific and medical consequences of substance use contributed to their continued substance use. Conversely, women highlighted the importance of high self-efficacy and the quality of relationships when trying to make positive changes to their substance use during pregnancy.Conclusions
Recommendations are proposed for easier access to and more comprehensive services. Healthcare professionals and service providers should offer non-judgmental care by building high-quality relationships with pregnant women with substance use issues, to increase these women’s self-efficacy and empower them to discontinue substance use. 相似文献138.
The structure of subjective well-being is analyzed by multidimensional mapping of evaluations of life concerns. For example, one finds that evaluations of Income are close to (i.e., relatively strongly related to) evaluations of Standard of living, but remote from (weakly related to) evaluations of Health. These structures show how evaluations of life components fit together and hence illuminate the psychological meaning of life quality. They can be useful for determining the breadth of coverage and degree of redundancy of social indicators of perceived well-being. Analyzed here are data from representative sample surveys in Belgium, Denmark, France, Germany, Great Britain, Ireland, Italy, Netherlands, and the United States (each N≈1000). Eleven life concerns are considered, including Income, Housing, Job, Health, Leisure, Neighborhood, Transportation, and Relations with other people. It is found that structures in all of these countries have a basic similarity and that the European countries tend to be more similar to one another than they are to USA. These results suggest that comparative research on subjective well-being is feasible within this group of nations. 相似文献

Real-time tracking of tool and equipment inventories is a critical function of many organizations and sectors. For prisons and correctional facilities, tracking and monitoring of assets such as cookware, hardware, keys, janitorial equipment, vocational/technical specialty tools, etc., is essential for safety, security, trust, efficiency, education, etc. The performance of automated systems for this purpose can be diminished by a variety of emergent and future sociotechnical factors alone and in combination. This article introduces a methodology for contractor evaluation and selection in acquisition of innovative asset management systems, with an emphasis on evolving system requirements under uncertainty. The methodology features a scenario-based preferences analysis of emergent and future conditions that are disruptive to the performance of the asset-control system. The conditions are across technologies, operating environments, regulations, workforce behaviors, offender behaviors, prices and markets, organizations, cyber threats, etc. The methodology addresses the influence and interaction of the conditions to disrupt system priorities. Examples include: (i) infectious disease disrupting priorities among requirements and (ii) radio-frequency identification (RFID) and wireless-technology innovations disrupting priorities among stakeholders. The combinations of conditions that most and least matter for the system acquisition are characterized. The methodology constitutes a risk register for monitoring sources of risk to project performance, schedule, and cost throughout the system lifecycle. The results will be of interest to both practitioners and scholars engaged in systems acquisition as the pandemic interacts with other factors to affect risk, uncertainty, and resilience of organizational missions and operations. 相似文献

This paper establishes the asymptotic distribution of an extremum estimator when the true parameter lies on the boundary of the parameter space. The boundary may be linear, curved, and/or kinked. Typically the asymptotic distribution is a function of a multivariate normal distribution in models without stochastic trends and a function of a multivariate Brownian motion in models with stochastic trends. The results apply to a wide variety of estimators and models. Examples treated in the paper are: (i) quasi-ML estimation of a random coefficients regression model with some coefficient variances equal to zero and (ii) LS estimation of an augmented Dickey-Fuller regression with unit root and time trend parameters on the boundary of the parameter space. 相似文献
