In-Sample Inference and Forecasting in Misspecified Factor Models

This article considers in-sample prediction and out-of-sample forecasting in regressions with many exogenous predictors. We consider four dimension-reduction devices: principal components, ridge, Landweber Fridman, and partial least squares. We derive rates of convergence for two representative models: an ill-posed model and an approximate factor model. The theory is developed for a large cross-section and a large time-series. As all these methods depend on a tuning parameter to be selected, we also propose data-driven selection methods based on cross-validation and establish their optimality. Monte Carlo simulations and an empirical application to forecasting inflation and output growth in the U.S. show that data-reduction methods outperform conventional methods in several relevant settings, and might effectively guard against instabilities in predictors’ forecasting ability.     

Good Job,Good Life? Working Conditions and Quality of Life in Europe

Cross-national comparisons generally show large differences in life satisfaction of individuals within and between European countries. This paper addresses the question of whether and how job quality and working conditions contribute to the quality of life of employed populations in nine strategically selected EU countries: Finland, Sweden, the UK, the Netherlands, Germany, Portugal, Spain, Hungary, and Bulgaria. Using data from the European Quality of Life Survey 2003, we examine relationships between working conditions and satisfaction with life, as well as whether spillover or segmentation mechanisms better explain the link between work domain and overall life satisfaction. Results show that the level of life satisfaction varies significantly across countries, with higher quality of life in more affluent societies. However, the impact of working conditions on life satisfaction is stronger in Southern and Eastern European countries. Our study suggests that the issue of security, such as security of employment and pay which provides economic security, is the key element that in a straightforward manner affects people’s quality of life. Other working conditions, such as autonomy at work, good career prospects and an interesting job seem to translate into high job satisfaction, which in turn increases life satisfaction indirectly. In general, bad-quality jobs tend to be more ‘effective’ in worsening workers’ perception of their life conditions than good jobs are in improving their quality of life. We discuss the differences in job-related determinants of life satisfaction between the countries and consider theoretical and practical implications of these findings.     

Linking Elderly to Holistic Care Services through Integrated Communication Technology: The Personal Emergency Link Service Rendered by the Senior Citizen Home Safety Association in Hong Kong

Through a Personal Emergency Link system, the Senior Citizen Home Safety Association has rendered 24-hour care to more than 111,000 service users in Hong Kong who are mostly vulnerable seniors and chronic invalids living alone or living with their elderly spouses/caregivers only. This article will describe how the Personal Emergency Link system is used to link seniors living in the community. Measures taken to prevent failure of the system will be described. With the use of different technology applications, many human touches and warm caregiving are rendered to the elderly and needy.     

Communicating Contaminant Risks from Sport-Caught Fish: The Importance of Target Audience Assessment

A fish consumption health advisory has existed for New York Lake Ontario sport-caught fish since 1978. Our study objectives were to evaluate the effectiveness of the advisory for reaching potential target audiences and to identify appropriate advisory content, style, and dissemination methods using a risk communication planning model as an evaluation framework. We used a combination of mail surveys and personal interviews with three target audiences (opinion leaders among recreational anglers and charter boat operators, migrant farm workers, and low-income individuals) and two communicator groups (fishery experts and health care experts). The New York Lake Ontario advisory appeared to be successful in reaching and encouraging risk-mitigating fish consumption behavior in recreational angler opinion leaders and low-income individuals but not in migrant farm workers. The advisory may not be reaching two sensitive subpopulations, women of childbearing age and children. Communicators and target audiences differed in their assessments of important information to include in an advisory. The health advisory could be improved with additional information such as risk-reducing cooking and cleaning methods and by diversifying the dissemination methods to reach the variety of audiences who potentially consume Lake Ontario fish.     

Importance of job analysis with functional capacity matching in medical case management: A physician's perspective

Medical case management of musculoskeletal injuries can be facilitated when objective testing of the physical demands of the job can be compared to the functional capabilities of the individual. When the job analysis is appropriately sectioned into the separate physical demands, the physician can use information about specific job demands to maximize the likelihood of a safe return to regular duties. The response in the physical abilities in the worker can then be again functionally evaluated, leading to increased confidence in the process.     

Preparation,support, and satisfaction of adoptive families in agency and independent adoptions

Information gathered from over 1000 adoptions in the fourth year of a prospective study of adoptions finds satisfaction levels to be quite high, with those families adopting through private agencies to feel best prepared and satisfied. Differences by adoption auspice are detailed and discussed.The senior authors are Co-Principal Investigators of the California Long-range Adoption Study. This research was supported by the Child Welfare Research Center, Family Welfare Research Group, University of California at Berkeley, through a grant from the Children's Bureau, Administration for Children and Families, Department of Health and Human Services. The authors wish to thank the families for their participation. Please address correspondence to Mary Berry at the Center for Child Welfare, UTA School of Social Work, P.O.

Black process in clinically depressed women: A conceptual framework for practice

Summary Emphasis throughout this paper has been placed on the importance of viewing black patients in their current social context. The positive impact of the Black Power movement has been observed in black patients who are involved in issues of black separatism and activism. Bennett's four stages of black process provide a means of identifying the position of individual blacks in terms of racial identity. Since relationships with whites are highly determined by the black patient's stage of black process, use of this conceptual frame work will assist the therapist in determining the indirect way in which black patients express racial issues.The author's experience has confirmed the existence and importance of two problem areas: the longer time needed to establish a therapeutic alliance in interracial work and the lack of knowledge of the black experience and culture in the white professional. The knowledge that additional time must be expended by both therapy partners must raise questions about the ethics of interracial practice and the need for more black mental health professionals. The second area of concern, the white professional's lack of knowledge, could be remedied. The fact that whites have not attempted to learn more about the black culture suggests the problem is a philosophical one. Liberal professionals are generally committed to the ideal of a truly integrated society where there are no differences among people. Black people appear to be telling us that they are different from whites here and now, and they like the difference.Supported by U.S.P.H.S.
