A number of governments and public policy institutes have developed Quality of Life Indexes – statistics that attempt to measure the quality of life for entire states or regions. We develop 14 criteria for determining the validity and usefulness of such QOL indexes to public policy. We then review 22 of the most-used QOL indexes from around the world. We conclude that many of the indexes are successful in that they are reliable, have established time series measures, and can be disaggregated to study subpopulations. However, many fall short in four areas: (1) indexes vary greatly in their coverage and definitions of domains of QOL, (2) none of the indexes distinguish among the concepts of input, throughput, and output that are used by public policy analysts, (3) they fail to show how QOL outputs are sensitive to public policy inputs, and (4) none have examined convergent validity against each other. We conclude that many of these indexes are potentially very useful for public policy and recommend research to further improve them. 相似文献

Using a stress and coping framework, we examined the influence of caregiving stressors, social support, and caregiving appraisal on the marital functioning of 100 African American wife caregivers. Results of separate multivariate analyses revealed received church support, caregiving burden, and caregiving satisfaction significantly predicted wives' marital functioning, when caregivers' background characteristics (age and education), length of caregiving, whether first marriage, and urban versus rural location were controlled. Receiving church support was associated with increased marital functioning. Lower levels of caregiving burden were associated with increased marital functioning. Higher levels of caregiving satisfaction were associated with increased marital functioning. Findings illuminate wives' caregiving and marital experiences, and have implications for family therapy and future research. 相似文献

A population of 72 bifocal wearers was studied to determine the relationship between VDT (video display terminal) placement for those who reported musculoskeletal pain and those who did not. The mean hours worked was 50.4 minutes (p=0.003) greater for those who reported head/neck pain versus those who did not and 48.6 minutes (p=0.004) greater for those who reported shoulder/arm pain that those who did not. There was no statistically significant difference between the means of monitor height, distance, or angle for those who reported pain symptoms versus those who did not. This study indicates that, self reported pain symptoms are correlated with hours of VDT work and that there appears to be a threshold at approximately five hours for pain symptoms among bifocal wearers. No such correlation can be made for monitor placement 相似文献

This paper introduces a new methodology ensuring units invariant slack selection in radial DEA models and incorporating the slacks into an overall efficiency score. The CCR and BCC models are units invariant in their radial component, but not in their slack component, thus changing the units of measurement of one or more variables can change the models' solution. The proposed Full Proportional Slack (FPS) methodology improves the slack selections of the CCR and BCC models by producing slack selections that (a) are units invariant, thus producing fully units invariant models, (b) maximize the relative improvements represented by the slacks, and not their values, and (c) measure the full slacks that need to be removed from their corresponding variables. The FPS methodology is a fully oriented methodology first maximizing the improvements in the variables on the side of the orientation of the model. The Proportional Slack Adjusted (PSA) methodology incorporates the FPS slacks into an overall efficiency score, making it easier to interpret and use the results. The FPS and PSA methodologies are illustrated using an input oriented VRS Loan Quality DEA model with data from the retail branch network of one of Canada's largest banks. 相似文献

Few publications exist on the reactions of children and adolescents to the serious illness of their therapist. This paper reviews the literature on the responses of adult patient’s and presents three vignettes of adolescents who were in treatment when their therapist was diagnosed with cancer. We discuss some of the theoretical and clinical issues these cases present and conclude that openly sharing an appropriate amount of information with the adolescents appears to further rather than impede the therapeutic process. 相似文献

The forecasts and assumptions of government and business regarding availability of labour are based in part on official statistics has been a matter of considerable debate in recent years. In this paper the author presents his views on the interpretation of the relevant U.K. statistics. 相似文献

We consider a generalization of the proportionate flow shop problem with the makespan objective. Each job has a processing
requirement and each machine has a characteristic value. In our case, we assume that the time a job occupies a machine is
equal to the processing requirement of the job plus a setup time that is equal to the characteristic value of that machine.
In this paper, we consider permutation schedules and show that the problem is solvable in polynomial time when the number
of machines is fixed. 相似文献
