Life Skills,Mathematical Reasoning and Critical Thinking: A Curriculum for the Prevention of Problem Gambling

Previous studies have shown that youth are two to three times more likely than adults to report gambling related problems. This paper reports on the development and pilot evaluation of a school-based problem gambling prevention curriculum. The prevention program focused on problem gambling awareness and self-monitoring skills, coping skills, and knowledge of the nature of random events. The results of a controlled experiment evaluating the students learning from the program are reported. We found significant improvement in the students' knowledge of random events, knowledge of problem gambling awareness and self-monitoring, and knowledge of coping skills. The results suggest that knowledge based material on random events, problem gambling awareness and self-monitoring skills, and coping skills can be taught. Future development of the curriculum will focus on content to expand the students' coping skill options.     

The detection of annual clusters in individual patterns of parasuicide

The anniversary model for the annual repetition of parasuicide (attempted suicide) is described. In order to demonstrate the existence of such effects in individuals, the Range Test for circular data is applied to data collected over a 2-year period from a specific case from the Edinburgh Regional Poisoning Treatment Centre. The use of this model in predicting future clusters of parasuicide episodes is then discussed.     

A Monte Carlo Risk Assessment Model for Acrylamide Formation in French Fries

The objective of this study is to estimate the likely human exposure to the group 2a carcinogen, acrylamide, from French fries by Irish consumers by developing a quantitative risk assessment model using Monte Carlo simulation techniques. Various stages in the French-fry-making process were modeled from initial potato harvest, storage, and processing procedures. The model was developed in Microsoft Excel with the @Risk add-on package. The model was run for 10,000 iterations using Latin hypercube sampling. The simulated mean acrylamide level in French fries was calculated to be 317 μg/kg. It was found that females are exposed to smaller levels of acrylamide than males (mean exposure of 0.20 μg/kg bw/day and 0.27 μg/kg bw/day, respectively). Although the carcinogenic potency of acrylamide is not well known, the simulated probability of exceeding the average chronic human dietary intake of 1 μg/kg bw/day (as suggested by WHO) was 0.054 and 0.029 for males and females, respectively. A sensitivity analysis highlighted the importance of the selection of appropriate cultivars with known low reducing sugar levels for French fry production. Strict control of cooking conditions (correlation coefficient of 0.42 and 0.35 for frying time and temperature, respectively) and blanching procedures (correlation coefficient −0.25) were also found to be important in ensuring minimal acrylamide formation.     

Calling Social Work

New Labour has promoted the use of information and communicationtechnology. Call centres are a key development in this strategyand are now in use for accessing social services. In officialpolicy, the use of call centres is presented as an aspect ofattempts to change the relationship between service users andthe purchasers and providers of services. In contrast, we suggestthat the use of call centres in social care does little to shiftthe balance of power. Call centres bring together four dimensionsof New Labour discourse: learning from the private sector, cuttingcosts, technology and consumerism. Three issues emerge fromtheir development: the undermining of social work’s senseof place; the circumscribing of service user participation;the rationalization of social workers. The call centre servesas a signifier of what, it is claimed, the combination of NewLabour’s consumerism and technology can achieve. Thissignification disguises call centres’ properties of efficiency,calculability, predictability and control. Contrary to the rhetoricthat accompanies them, call centres may be curtailing serviceuser participation, as well as delimiting the social work role.Accordingly, their use has important, but as yet largely unresearched,implications for service users and social workers.     

Source Attribution of Food-Borne Zoonoses in New Zealand: A Modified Hald Model

A Bayesian approach was developed by Hald et al .^{( 1 )} to estimate the contribution of different food sources to the burden of human salmonellosis in Denmark. This article describes the development of several modifications that can be used to adapt the model to different countries and pathogens. Our modified Hald model has several advantages over the original approach, which include the introduction of uncertainty in the estimates of source prevalence and an improved strategy for identifiability. We have applied our modified model to the two major food-borne zoonoses in New Zealand, namely, campylobacteriosis and salmonellosis. Major challenges were the data quality for salmonellosis and the inclusion of environmental sources of campylobacteriosis. We conclude that by modifying the Hald model we have improved its identifiability, made it more applicable to countries with less intensive surveillance, and feasible for other pathogens, in particular with respect to the inclusion of nonfood sources. The wider application and better understanding of this approach is of particular importance due to the value of the model for decision making and risk management.     

Corporate long-range planning groups—Some different approaches

This paper investigates several atypical roles of formal long-range planning groups and some reasons for their appearance. The study is based on three separate surveys covering 115 companies in eight industries located in both England and the United States. The authors first identify functions based on their own research and the literature which appear to make up a typical planning group role. Twenty-four of the 115 planning groups surveyed very considerable as well as sytematically from the norm. They are classified into three major categories described as (1) capital budgeting groups, (2) project development groups, and (3) think tank groups.
