How Good a Deal Was the Tobacco Settlement?: Assessing Payments to Massachusetts

We estimate the increment in Massachusetts Medicaid program costs attributable to smoking from December 20, 1991 to 1998. We describe how our methods improve upon earlier estimates of analogous costs at the national level. Current costs to the Massachusetts Medicaid program approximate the payments to Massachusetts under the tobacco settlement of November 1998. Whether these payments are viewed as appropriate compensation for Medicaid costs over time depends upon the rate of increase in future health care costs, the rate of decline in smoking, the proportion of smoking that should be attributed to the actions of the tobacco companies and the likelihood the state would have prevailed at trial. The costs to the Medicaid program are dwarfed by the internal costs to smokers themselves.     

Efficient use of exact samples

Propp and Wilson (Random Structures and Algorithms (1996) 9: 223–252, Journal of Algorithms (1998) 27: 170–217) described a protocol called coupling from the past (CFTP) for exact sampling from the steady-state distribution of a Markov chain Monte Carlo (MCMC) process. In it a past time is identified from which the paths of coupled Markov chains starting at every possible state would have coalesced into a single value by the present time; this value is then a sample from the steady-state distribution.Unfortunately, producing an exact sample typically requires a large computational effort. We consider the question of how to make efficient use of the sample values that are generated. In particular, we make use of regeneration events (cf. Mykland et al. Journal of the American Statistical Association (1995) 90: 233–241) to aid in the analysis of MCMC runs. In a regeneration event, the chain is in a fixed reference distribution– this allows the chain to be broken up into a series of tours which are independent, or nearly so (though they do not represent draws from the true stationary distribution).In this paper we consider using the CFTP and related algorithms to create tours. In some cases their elements are exactly in the stationary distribution; their length may be fixed or random. This allows us to combine the precision of exact sampling with the efficiency of using entire tours.Several algorithms and estimators are proposed and analysed.     

Web-based nutrition education for college students: Is it feasible?

College students have poor nutrition habits and often exhibit at-risk weight control behaviors; yet, health promotion efforts on campuses often target other risk behaviors such as alcohol and tobacco use. The goal of this study was to determine program content and examine the feasibility of a web-based nutrition education program for college students using innovative applications of tailoring, targeting and personalization of information. Comprehensive program planning entailed three phases: focus groups and use of concept mapping methodology, prototype web program development, and feasibility testing of the prototype. Results of concept mapping suggested that students and experts agreed on the relative importance of the major content areas unique to the college audience. A prototype web program, informed by health promotion theories, was developed and evaluated. Students and college health professionals participated in the feasibility evaluation, which included acceptance and usability testing of the prototype. Mean scores were computed for the acceptance ratings that indicated that the prototype web program was not only feasible, but also compelling and relevant for the college audience. In conclusion, a tailored, web-based interactive nutrition program could potentially be used to provide individualized nutrition information to encourage college students to adopt healthy eating behaviors.     

Introducing the MiniPONS: A Short Multichannel Version of the Profile of Nonverbal Sensitivity (PONS)

Despite extensive research activity on the recognition of emotional expression, there are only few validated tests of individual differences in this competence (generally considered as part of nonverbal sensitivity and emotional intelligence). This paper reports the development of a short, multichannel, version (MiniPONS) of the established Profile of Nonverbal Sensitivity (PONS) test. The full test has been extensively validated in many different cultures, showing substantial correlations with a large range of outcome variables. The short multichannel version (64 items) described here correlates very highly with the full version and shows reasonable construct validity through significant correlations with other tests of emotion recognition ability. Based on these results, the role of nonverbal sensitivity as part of a latent trait of emotional competence is discussed and the MiniPONS is suggested as a convenient method to perform a rapid screening of this central socioemotional competence.     

ABOUT THE AUTHORS

Work satisfaction, self‐esteem, and alienation measures were obtained from white males in three service occupations (bartenders, barbers, and mailmen) at different levels of the occupational prestige hierarchy. While we found an overall positive relationship between work satisfaction and occupational prestige, this only held for variables where societal reference groups were forced upon the respondents. Such findings suggest that the relationship between work satisfaction and occupational prestige is less absolute than usually suggested by the literature. Hypotheses from the literature arguing for a direct relationship between occupational prestige and alienation were not supported by our data. We conclude that sociologists probably overestimate the salience of work and occupational prestige for the working class.     

Use of an ISO 14000 Option in Implementing EPA's Rule on Risk Management Programs for Chemical Accidental Release Prevention

EPA's rule of Risk Management Programs for Chemical Accidental Release Prevention applies to facilities that manufacture, process, use, store, or otherwise handle regulated substances at or above specified threshold quantities. EPA estimates that approximately 66,000 facilities nationwide will be regulated under the rule. This paper examines the use of a structured ISO 14000 mechanism as option-regulated facilities could elect for implementation of the rule. Under the ISO 14000 option, facilities would commit to additional obligations regarding information disclosure, discussions with potentially affected publics, and timely correction of deficiencies noted in annual ISO 14000 audits of their compliance with the Risk Management Program they submit to the EPA under the rule. In return, facilities would be granted significant relief in regard to both EPA audit frequency and the penalties that might be applied for any items of noncompliance with the rule noted during the course of implementing agency reviews of the facility. The paper concludes with a discussion of the advantages and disadvantages of this option to potentially affected stakeholders.
