The gap in social care provision for older people in China

Because of its unprecedented sociodemographic changes, particularly rapid population aging, China faces huge challenges in social care. Using data from the 2012 Chinese Longitudinal Healthy Longevity Survey (n = 9,765), this article examines the need for social care, as well as the major sources of provision. The findings indicate that the majority of older people face some restriction in their daily living activities. From their perspective, however, the most urgent social protection services are related to health care and legal aid rather than services supporting daily living. Although Chinese Government policy since the 1990s has been a strategy of social welfare socialization, the role of government, both as provider and funder, is limited and focuses only on the most deprived and on urban areas. The result is a massive “care gap” between the need for social care and its supply. The primary responsibility for care provision is borne by the family. The direction of social policy in the future should focus on shared care between the family and the state, giving priority to expanding the coverage of social care services, especially in rural areas.     

A Cautionary Note on Beta Families of Distributions and the Aliases Within

In this note, we examine the four parameter beta family of distributions in the context of the beta-normal and beta-logistic distributions. In the process, we highlight the concept of numerical and limiting alias distributions, which in turn relate to numerical instabilities in the numerical maximum likelihood fitting routines for these families of distributions. We conjecture that the numerical issues pertaining to fitting these multiparameter distributions may be more widespread than has originally been reported across several families of distributions.     

A modified two-stage approach for joint modelling of longitudinal and time-to-event data

Joint models for longitudinal and time-to-event data have been applied in many different fields of statistics and clinical studies. However, the main difficulty these models have to face with is the computational problem. The requirement for numerical integration becomes severe when the dimension of random effects increases. In this paper, a modified two-stage approach has been proposed to estimate the parameters in joint models. In particular, in the first stage, the linear mixed-effects models and best linear unbiased predictorsare applied to estimate parameters in the longitudinal submodel. In the second stage, an approximation of the fully joint log-likelihood is proposed using the estimated the values of these parameters from the longitudinal submodel. Survival parameters are estimated bymaximizing the approximation of the fully joint log-likelihood. Simulation studies show that the approach performs well, especially when the dimension of random effects increases. Finally, we implement this approach on AIDS data.

Microarrays as a tool to investigate the biology of aging: a retrospective and a look to the future

The use of microarrays as a tool to investigate fundamental biological questions has become ubiquitous over the past several years. Microarrays are becoming as common as the polymerase chain reaction or any of the other tools in the molecular biologist's armory. Unlike experiments involving other tools, however, the design and analysis of microarray experiments present some unique problems to molecular biologists, problems with which statisticians have long been familiar. In this overview of microarrays and aging-related research, we will review selected highlights of microarray studies that have been carried out to study aging to date, as well as discuss some of the potential problems that routinely arise during these types of experiments, especially in the context of aging.     

Implementing a smoking ban in an acute psychiatric admissions unit

In contrast to general medical hospitals, psychiatric hospitals often allow patients to smoke cigarettes. In addition to obvious health concerns, smoking can also interfere with clinical assessments and therapeutic activities, Implementation of a smoking ban on an acute male admissions unit did not result in any increase in aggressive behaviors. In addition, staff attitudes following the ban improved, and most staff members believed the ban was both ethical and beneficial to patients. Our research indicates that banning smoking on an acute admissions unit is feasible and well tolerated by patients and staff, although it may require extra vigilance for smoking-related contraband.     

The scientist-practitioner model in marriage and family therapy doctoral programs: current status

We discuss the status of the scientist-practitioner model in marriage and family therapy (MFT) doctoral programs. Issues discussed include a lack of faculty research role models in doctoral programs, "farming out" the majority of research courses to other disciplines, problems with curriculum, and how the culture of MFT does not support research. We also present suggestions for improving doctoral research training. The goal is to improve the quality of research training in doctoral programs. We hope that this will help change the culture of MFT to include research as one of its primary goals and greatest assets.     

Computer environments for children: a review of design issues

Ergonomic design considerations for computer use in schools are reviewed. Evidence for the postural effects of ergonomic furniture from worldwide studies is evaluated. Issues of furniture sizing and allocation methods are discussed. The limited evidence for effects of input device design on schoolchildren is summarized. Future directions for ergonomic research studies are presented.     

Physical activity among ethnically diverse college students

The authors compared physical activity patterns among 874 Asian, 332 African, 1,101 White, and 529 Hispanic American college students aged 18 to 25 years. According to self-report responses, 46.7% of the sample did not engage in vigorous physical activity and 16.7% were physically inactive. Among women, ethnic-specific rates of physical inactivity were Asian, 28.1%; African, 23.5%; White, 17.4%; and Hispanic, 20.3%. For men, rates of inactivity were Asian 11.7%; African, 7.7%; White, 12.0%; and Hispanic, 13.8. Weight-training activity, youthful physical activity, and TV viewing accounted for a significant portion of the variance in physical activity levels (13.1% for women and 14.8% for men). The results of this study support the need for physical activity interventions for college students, particularly minorities.
