Alcohol Misuse Among Older Adult Public Housing Residents

Low-income older adults living in public housing are at heightened risk for substance misuse. This study identified the prevalence of alcohol misuse among older public housing residents (n?=?187) and explored predictors of problem drinking. Including weekly drinking levels and binge drinking, 23% of the sample engaged in problem drinking behaviors. Logistic regression analysis revealed that race, gender, employment status, years smoking, and illegal drug use were significant predictors of problem drinking. No residents were receiving substance abuse treatment. As the number of older adults increase, training social workers to assess and treat alcohol misuse in older adults is critical.     

Online Teaching in Social Work Education: Understanding the Challenges

There is a rapidly growing industry of online learning and distance education programs at the Master of Social Work and Bachelor of Social Work levels both within Australia and globally. A number of best practices have emerged from the literature that warrant consideration when delivering social work programs in online learning and distance education modes. Given the significant advancements in technology that are likely to continue into the next decades, social work academic leaders and accrediting bodies must be prepared to address the changing landscape of higher education, including limited financial resources. Social work academics need to become aware and implement best practices in online learning and distance education e-teaching environments to ensure positive student outcomes, student retention, and student engagement to meet the flexibility needs of students in higher education settings. The purpose of this paper is to identify and discuss the challenges and benefits of distance education and online learning for consideration when providing a social work program in these delivery models.

IMPLICATIONS

• Given the significant advancements in technology that are likely to continue into the next decades, social work academic leaders and accrediting bodies must be prepared to address the changing landscape of higher education.

• Social work academics need to become aware and implement best practices in the distance education and online teaching environment to ensure positive student outcomes, student retention, and student engagement to meet the flexibility needs of students in higher education settings.

     

Day versus residential treatment for juvenile offenders: the impact of program evaluation

A case study of a public service department's program evaluation provides insights into the social policy-making process as well as findings on the effectiveness of two different forms of treatment for the same social problem.     

Comparing Opinions of People with Developmental Disabilities and Significant Persons in their Lives Using the Individual Supports Identification System (ISIS)

Fifty-two people with developmental disabilities were interviewed using the Individual Supports Identification System (ISIS). This study reports on persons with developmental disabilities, served by the State of Washington Division of Developmental Disabilities, and includes persons whose onset of disability was prior to 18. To be eligible for services, an individual must have a disability that falls within one of the following categories: (1) mental retardation; (2) cerebral palsy; (3) epilepsy; (4) autism; and (5) other types of central nervous system impairment closely related to mental retardation. Interviews were conducted with two groups. The first comprised individuals with developmental disabilities and the second, significant persons in the life of each participant in the first group. A significant person was considered to be someone known by the individual with disabilities for more than 6 months, spending more time with him or her than others. In addition, the significant person must like the individual with disabilities, and have his or her best interests in mind. Seventy-five per cent of significant persons interviewed were parents. Significant persons also responded to a series of ISIS questions. Responses from the individual with disabilities and from the significant person in his or her life were compared in order to determine similarities and differences in perspective. Comparisons focus on issues pertaining to friends and relationships, living environment and daily care needs.     

Forecasting future values of changing sequences

Sequences of independent random variables are observed and on the basis of these observations future values of the process are forecast. The Bayesian predictive density of k future observations for normal, exponential, and binomial sequences which change exactly once are analyzed for several cases. It is seen that the Bayesian predictive densities are mixtures of standard probability distributions. For example, with normal sequences the Bayesian predictive density is a mixture of either normal or t-distributions, depending on whether or not the common variance is known. The mixing probabilities are the same as those occurring in the corresponding posterior distribution of the mean(s) of the sequence. The predictive mass function of the number of future successes that will occur in a changing Bernoulli sequence is computed and point and interval predictors are illustrated.     

Bayesian inferences related to shifting sequences and two-phase regression

The problem of estimating the switch point in a sequence of independent random variables is studied from a Bayesian viewpoint. Theoretical results and numerical examples are given for the normal sequence and two-phase regression.     

Estimating the parameters of mixed linear models with modal estimators

This paper presents a procedure to estimate the variance components and fixed effects of mixed linear models. The mode of the joint posterior distribution of all the parameters is obtained by an iterative technique.

The proposed method is illustrated with one-way and two-fold nested random models. Two numerical examples demonstrate the iterative solution.     

Testing for a change lit the regression matrix of a multivariate linear model

A Bayesian test procedure Is developed to test; the null hypothesis of no change In the regression matrix of a multivariate lin¬ear model against the alternative hypothesis of exactly one change The resulting test is based on the marginal posterior distribution of the change point; To illustrate the test procedure a numerical example using a bivariate regression model is considered.     

A bayesian analysis of the mixed linear model

The mixed model is defined. The exact posterior distribution for the fixed effect vector is obtained. The exact posterior distribution for the error variance is obtained. The exact posterior mean and variance of a Bayesian estimator for the variances of random effects is also derived. All computations are non-iterative and avoid numerical integrations.     

A COMPARISON OF THE IMPRECISE BETA CLASS, THE RANDOMIZED PLAY-THE-WINNER RULE AND THE TRIANGULAR TEST FOR CLINICAL TRIALS WITH BINARY RESPONSES

This paper develops clinical trial designs that compare two treatments with a binary outcome. The imprecise beta class (IBC), a class of beta probability distributions, is used in a robust Bayesian framework to calculate posterior upper and lower expectations for treatment success rates using accumulating data. The posterior expectation for the difference in success rates can be used to decide when there is sufficient evidence for randomized treatment allocation to cease. This design is formally related to the randomized play‐the‐winner (RPW) design, an adaptive allocation scheme where randomization probabilities are updated sequentially to favour the treatment with the higher observed success rate. A connection is also made between the IBC and the sequential clinical trial design based on the triangular test. Theoretical and simulation results are presented to show that the expected sample sizes on the truly inferior arm are lower using the IBC compared with either the triangular test or the RPW design, and that the IBC performs well against established criteria involving error rates and the expected number of treatment failures.
