Problem gambling in the workplace, characteristics of employees seeking help

Few rigorous research studies exist to define the impact problem gambling may have on the workforce and the workplace. This study is an initial attempt to address this void by exploring the vocational patterns and demographics of callers with self report gambling problems to a state helpline. It utilizes Chi-squared Automatic Interaction (CHAID) Technique analysis to assess 1072 working age callers with gambling related problems. The goal of this exploratory investigation is to determine if the issue of problem gambling in the workplace warrants further research and, potentially, design of interventions. Discussion centers on the use of the information for development of employer based prevention and intervention efforts.     

Field Instructor Benefits in Education

This article provides a comprehensive overview of benefits awarded to agency-based social work field instructors. Findings from a national survey of undergraduate and graduate social work programs in the United States confirmed differences in the nature of benefits awarded to undergraduate and graduate field instructors. In addition, study findings revealed variations in the pattern of awarded benefits among regions and among schools of varying size. The most frequently awarded benefits included use of the library holdings or equipment, continuing education programs, and official designation as adjunct faculty member. The authors suggest that, given the current economic atmosphere, programs become more creative in their provision of benefits that are attractive but inexpensive. Moreover, the authors recommend that the profession seek to understand better what motivates field instructors.     

Local therapy facilitators working with children with developmental delay in rural and remote areas of western New South Wales,Australia: the ‘Outback’ service delivery model

Australia's dispersed population in rural areas contributes to poor access to therapy services and the inability of the existing rural therapy workforce to meet demand. As a result, rural children with a developmental delay wait a long time for therapy. This paper describes participant perceptions of a therapy facilitation service model that has worked to improve access to therapy for children in these circumstances. The model, given the pseudonym ‘Outback’, operates in rural and remote areas of western New South Wales. ‘Outback’ employs local people to work under the guidance of therapists based in larger centres to provide preschool children with developmental delays with access to therapy interventions they might not otherwise receive. A two‐stage case study design involving focus groups and interviews with the director, four therapy facilitators, nine therapists, and seven carers was used. Three themes were identified as central to the service model: 1) being part of the local community; 2) developing therapy facilitator knowledge and skills; 3) improving access to therapy intervention for children in rural and remote areas. The ‘Outback’ model demonstrates that appropriately supported, local therapy facilitators provide a flexible workforce adjunct that expands the reach of therapists into rural and remote communities and enhances service access for children and their families.     

Do Central Bank Liquidity Facilities Affect Interbank Lending Rates?

In response to the global financial crisis that started in August 2007, central banks provided extraordinary amounts of liquidity to the financial system. To investigate the effect of central bank liquidity facilities on term interbank lending rates near the start of the crisis, we estimate a six-factor arbitrage-free model of U.S. Treasury yields, financial corporate bond yields, and term interbank rates. This model can account for fluctuations in the term structure of credit and liquidity spreads observed in the data. A significant shift in model estimates after the announcement of the liquidity facilities suggests that these central bank actions did help lower the liquidity premium in term interbank rates.     

A New Method for Determining Why Length of Life is More Unequal in Some Populations Than in Others

Why is there greater variability in individual longevity in some populations than in others? We propose a decomposition method designed to address that question by quantifying the effects of population differences in the spread, allocation, and timing of the principal causes of death. Applying the method to the United States and Sweden, we find that spread effects account for about two-thirds of the greater variance in age at death among American adults, meaning that two-thirds of the U.S.-Sweden difference would persist if the two countries differed only with respect to within-cause variance among adults. The remainder of the difference is due largely to allocation effects, with the greater incidence of homicides and fatal traffic accidents alone accounting for more than one-fourth of the greater variance in age at death among adults in the United States.     

On cramér-von mises tests of goodness of fit with censored data

The paper considers the goodness of fit tests with right censored data or doubly censored data. The Fredholm Integral Equation (FIE) method proposed by Ren (1993) is implemented in the simulation studies to estimate the null distribution of the Cramér-von Mises test statistics and the asymptotic covariance function of the self-consistent estimator for the lifetime distribution with right censored data or doubly censored data. We show that for fixed alternatives, the bootstrap method does not estimate the null distribution consistently for doubly censored data. For the right censored case, a comparison between the performance of FIE and the η out of η bootstrap shows that FIE gives better estimation for the null distribution. The application of FIE to a set of right censored Channing House data and to a set of doubly censored breast cancer data is presented.     

Using Probabilistic Modeling to Evaluate Human Exposure to Organotin in Drinking Water Transported by Polyvinyl Chloride Pipe

The leaching of organotin (OT) heat stabilizers from polyvinyl chloride (PVC) pipes used in residential drinking water systems may affect the quality of drinking water. These OTs, principally mono- and di-substituted species of butyltins and methyltins, are a potential health concern because they belong to a broad class of compounds that may be immune, nervous, and reproductive system toxicants. In this article, we develop probability distributions of U.S. population exposures to mixtures of OTs encountered in drinking water transported by PVC pipes. We employed a family of mathematical models to estimate OT leaching rates from PVC pipe as a function of both surface area and time. We then integrated the distribution of estimated leaching rates into an exposure model that estimated the probability distribution of OT concentrations in tap waters and the resulting potential human OT exposures via tap water consumption. Our study results suggest that human OT exposures through tap water consumption are likely to be considerably lower than the World Health Organization (WHO) "safe" long-term concentration in drinking water (150 μg/L) for dibutyltin (DBT)—the most toxic of the OT considered in this article. The 90th percentile average daily dose (ADD) estimate of 0.034 ± 2.92 × 10⁻⁴μg/kg day is approximately 120 times lower than the WHO-based ADD for DBT (4.2 μg/kg day).
