Towards a theoretical clarification of the ‘spillover’ and ‘compensatory’ work/leisure hypotheses

Two thorny problems have attracted the interest of work/leisure researchers in recent years: (1) the failure of previous research to clearly isolate the relationship between work and non-work from the effects of other confounding variables, and (2) a widespread failure to distinguish between the meanings that people attribute to work (and non-work) and the forms of work (and non-work) people perform. The argument for phenomenological research is made; in this way, empirically-grounded ‘common sense’ definitions of work and leisure could be created and these definitions could be used as a solid research base to test ‘spillover’ and ‘compensatory’ theories of the work/leisure relationship. The author then demonstrates, through the development of an analytic framework for viewing the work/leisure relationship, the fact that ‘compensatory’ and ‘spillover’ hypotheses are potential alternative modes of explanation. Unless the conditions under which each might apply can be specified, one or the other hypothesis can explain a given empirical relationship between the two variables. This further supports the need for solid phenomenological research.     

Estimating the Risks of Smoking, Air Pollution, and Passive Smoke on Acute Respiratory Conditions

Five years of the annual Health Interview Survey, conducted by the National Center for Health Statistics, are used to estimate the effects of air pollution, smoking, and environmental tobacco smoke on respiratory restrictions in activity for adults, and bed disability for children. After adjusting for several socioeconomic factors, the multiple regression estimates indicate that an independent and statistically significant association exists between these three forms of air pollution and respiratory morbidity. The comparative risks of these exposures are computed and the plausibility of the relative risks is examined by comparing the equivalent doses with actual measurements of exposure taken in the homes of smokers. The results indicate that: (1) smokers will have a 55-75% excess in days with respiratory conditions severe enough to cause reductions in normal activity; (2) a 1 microgram increase in fine particulate matter air pollution is associated with a 3% excess in acute respiratory disease; and (3) a pack-a-day smoker will increase respiratory restricted days for a nonsmoking spouse by 20% and increase the number of bed disability days for young children living in the household by 20%. The results also indicate that the estimates of the effects of secondhand smoking on children are improved when the mother's work status is known and incorporated into the exposure estimate.     

Evidence of fertility regulation among rural french villagers, 1749–1789

In this first part an econometric model describing the sequences of live births to individual couples is developed and estimated, using data for a sample of married women in rural French communes during the period 1749–1789. The main methodological objective is to devise a means of controlling for unobserved heterogeneities that result in the endogeneity of variables describing a couple's accumulated demographic experience. Without such controls it is not possible to secure unbiased estimates of responses to familial demographic events, such as the births and deaths of children. Such estimates are sought here as indirect indicators of the existence and nature of deliberate fertility control.Un modèle économétrique, décrivant la suite des naissances vivantes d'un couple donné, est développé et estimé dans cette première partie, en utilisant des données sur un échantillon de femmes mariées dans des communes rurales françaises durant la période 1749–1789. Le principal objectif méthodologique est de fournir un moyen de contrôler l'hétérogénéité non observée qui résulte de variables endogènes décrivant l'expérience cumulative d'un couple. Sans un tel contrôle il n'est pas possible d'obtenir des estimations sans biais de l'effet d'événements démographiques, tels que les naissances et les décès d'enfants. De tels estimateurs sont recherchés ici en vue de fournir des indications indirectes sur l'exercice et la nature d'une prévention des naissances délibérée.

The Role of Work in Adolescent Development

This commentary discusses the articles in the special section, “Adolescent Career Development in Social Context.” Initially, common and integrative themes are identified and explicated based on the diverse perspectives of the work role in adolescence that were evident in these five articles. In addition, the theoretical frameworks provided by life-span, career development relational perspectives are discussed as possible means of integrating some of the findings presented by the authors of these articles. This article concludes with an observation on how the findings reported in the special section can inform career development scholarship and practice in the next millennium.     

Conservatism of the Accident Sequence Evaluation Program HRA Procedure

This paper presents a limited assessment of the conservatism of the Accident Sequence Evaluation Program (ASEP) human reliability analysis (HRA) procedure described in NUREG/CR-4772. The data for this study are derived from simulator examination reports from the NRC requalification examination cycle for nuclear power plant operators. The ASEP procedure was used to estimate human error probability (HEP) values for critical tasks, and the HEP results were compared with the failure rates observed in the examinations. The ASEP procedure was applied by PNNL operator license examiners who supplemented the limited information in the examination reports with expert judgment based upon their extensive simulator examination experience. Comparison of the average of the ASEP HEP values with the fraction of the population actually failed and demonstrated that the ASEP HEP values are larger (conservative) by a statistically significant average factor of two. Partitioning of tasks into subgroups based on the ASEP HEP values and comparison of the subgroup average ASEP HEP values with observed subgroup failure rates showed little or no conservatism for small ASEP HEP values, but considerable conservatism for larger ASEP HEP values.     

Who volunteers?

Summary The 1990 NHS and Community Care Act outlined an extended rolefor volunteers and voluntary organizations in the provisionof services for disabled adults and older people. In broad terms,the Act assumed an untapped pool of volunteers, ready to contributeat little additional cost to the provision of care. More recentpolicy developments, including Millennium Volunteers (ScottishOffice 1997) have made similar assumptions. For organizationswhich involve volunteers, the expectations of their increaseduse in service provision present considerable challenges, notleast in attracting new recruits and retaining existing volunteers.The research presented in this paper builds on previous workto explore the current practice and organization of volunteeringand to examine critically how far the reality matches the politicalrhetoric about the role of volunteers in the mixed economy ofcare. The paper begins with a critical review of recent policyand practice in volunteering to set the context which providedour key questions. The research methodology is briefly describedand the findings from a survey of 117 active volunteers workingwith adults with learning difficulties, mental health problemsand physical disabilities, and with older people in the Northof Scotland are presented. The research examines the demographyand personality profiles of the volunteers. It examines theirperceptions of volunteering as these relate to motivation, recruitment,selection, training, support, rewards and reasons for leaving.Finally, it examines volunteers' perceptions of the organizationof volunteering. The results are reviewed in relation to thepolicy assumptions about volunteering in the mixed economy ofcare.     

Statistical Inference Based on Pooled Data: A Moment-Based Estimating Equation Approach

We consider statistical inference on parameters of a distribution when only pooled data are observed. A moment-based estimating equation approach is proposed to deal with situations where likelihood functions based on pooled data are difficult to work with. We outline the method to obtain estimates and test statistics of the parameters of interest in the general setting. We demonstrate the approach on the family of distributions generated by the Box-Cox transformation model, and, in the process, construct tests for goodness of fit based on the pooled data.     

Domain specificity of fairness judgments in economic transactions

Two studies eliciting fairness judgments about hypothetical economic transactions examined whether fairness judgments were influenced by who was being judged. The first study replicated the results of Kahneman et al. (Am. Econom. Rev. 76 (1986a) 728–741; J. Business 59 (1986b) S285–S300) that people judge certain actions by firms as unfair, but it also demonstrated that people judge parallel actions by individuals as fair. The second study suggested that people apply different standards to individuals and firms because of presumed differences between them in wealth, power, and size. When firms were portrayed as no more powerful or wealthy than individuals, differences in fairness judgments were eliminated. Further, respondents were less inclined to judge the behavior of a firm harshly as perpetrator of an unfair act when the firm was identified with an individual than when it was large and anonymous, and they were more inclined to judge the behavior of an individual harshly as perpetrator of an unfair act when the action injured a firm with a clearly identified individual than when the firm was large and anonymous.
