On 'class exploitation' in Canada†

Two things make Carl Cuneo's recent (1978) paper on 'rates of exploitation' in Canada remarkable. The first is the magnitudes involved. Cuneo's preferred measure of surplus value (RSV₇), for instance, shows a more than seven-fold increase from 1917 to 1971, indicating a quite spectacular shift in favour of capital in relative income shares in Canadian manufacturing industry. The second thing that makes Cuneo's paper remarkable is the extent to which his findings are inconsistent with findings on income shares reported by 'bourgeois' economists. In a survey of the literature Pen (1971: 164 ff.), for example, reports that in the advanced capitalist economies, the share of income accruing to labour in the economy as a whole has increased substantially and that even if one confines one's attention to the private sector the share of manual workers has not decreased but remained more or less constant in spite of the relative decline in their numbers.¹ Now, it is true that the studies reviewed by Pen approach the problem of income shares with the categories of 'bourgeois' economics while Cuneo approaches the problem with what he regards as Marxist categories, and it is conceivable that this might have accounted for the radical difference in the findings. But still, differences of such magnitude in the trends reported in the shares of capital and labour both give pause and urge a close scrutiny.     

Delabeling and relabeling in Gamblers Anonymous: Problems with transferring the Alcoholics Anonymous paradigm

Exploratory data from both structured and unstructured interviews with members of Alcoholics Anonymous and Gamblers Anonymous, as well as additional data from previous observations, suggest that the recovery rate of A.A. is higher than that of G.A.. Since the programs are virtually the same an examination of the social context of the labeling process reveals that the more readily available use of the medical model for both the alcoholic and the significant others of the alcoholic are likely significant differences between the compulsive gambler and the compulsive drinker.An embryonic version of this paper was presented at the Second Annual Conference on Gambling, Lake Tahoe, August 1975. The authors thank Henry Lesieur, Robert Custer, and the anonymous reviewers ofThe Journal of Gambling Behavior for their comments and suggestions. We give special thanks to Dan, Howie, Jeanne, Berdell, Barbara, John, Swede, Happy Jack, Nancy, Skip, and many other anonymous members of G.A. and A.A. for their help and cooperation in this study.     

Auditory Stream Segregation Improves Infants' Selective Attention to Target Tones Amid Distractors

The present study examined the role of auditory stream segregation in the selective attention to target tones in infancy. Using a task adapted from Bregman and Rudnicky's (1975) study and implemented in a conditioned head-turn procedure, infant and adult listeners had to discriminate the temporal order of 2200 and 2400 Hz target tones presented alone, preceded and followed by 1460 Hz flanker tones, and presented within a series of 1460 Hz captor tones meant to release the target tones from the effects of the flankers by capturing the flankers into a separate stream. Infants showed the same pattern of discrimination across conditions as adults: discrimination of target tones in the target-alone condition, a decrease in performance when flanker tones were introduced, and a return to target-alone level in the captor condition. These results suggest that infants' perceptual organization of tones is similar to that of adults, and that their ability to selectively attend to target sounds and ignore distractors depends on the structural properties and perceptual organization of the non-target sounds.     

Rock Up: An initiative supporting students' wellbeing in their transition to secondary school

This paper reports the background and findings of the community-based pilot program ‘Rock Up’ to school. The Rock Up program was directed at a niche section of young students in Grades 5, 6, and 7 to respond to identified risk factors associated with disengagement from formal education. The Rock Up approach was to energise these students' connection to learning as they approach the difficult stage of transition from primary school to secondary school. Ultimately, Rock Up aims to assist those students in their development of wellbeing, within and outside of the school environment. The operational measures of wellbeing covered; academic, social, emotional, behavioural, and school absence. Thirteen students, who had been identified by their respective teachers, were invited to participate in individual and/or group activities that focused on their wellbeing and developing their readiness for secondary school. Written and verbal feedbacks from students, teachers, parents, and the program facilitator, were in the main very positive. Analysis of the data of the first round of the program using a three-wave questionnaire and a participatory action research approach indicated the need to proceed to a new round using more refined processes. When fully developed, Rock Up is intended to be the vanguard for collaborative practice between the education and community sectors throughout Victoria and to be an example of an efficient and effective model of transition for this age-group.     

The effects of drinking status and believability of ads featured in a social norms campaign on college students' estimation and accuracy of other students' celebratory drinking

This study examined estimation and accuracy of normative perceptions for students during one celebratory drinking occasion. Students who drank on St. Patrick's Day overestimated the percentage of others who also drank, whereas the students who did not drink on St. Patrick's Day underestimated the percentage of others who also did not drink. The students' drinking behaviors on St. Patrick's Day did not substantially differentiate their accuracy scores. However, of the students who drank on St. Patrick's Day, those who did not believe the ads showed stronger overestimation of others who drank than did those who believed the ads.     

The subjective dimension of social isolation: A qualitative investigation of older adults' experiences in small social support networks

In the aging literature, social isolation has been primarily defined in terms of reduced support network size and low frequency of social contacts. Having a small social support network is associated with social isolation and an increased risk of physical and emotional vulnerability. However, this conceptualization ignores the contributions of a host of other factors, including life experiences, family dynamics, and long-term patterns of socialization. This paper argues that alongside quantitative assessments of support systems, the application of a life course perspective is needed to understand small social networks as lived experience. We report on findings from 28 in-depth interviews with older adults identified as being at risk of social isolation on the basis of the self-reported size of their social networks. We discuss these participants' experiences in the context of significant life course transitions such as marriage and widowhood.     

Effects of neighborhood walkability on healthy weight: assessing selection and causal influences

Studies that examine the relationship between neighborhood characteristics and weight are limited because residents are not randomly distributed into neighborhoods. If associations are found between neighborhood characteristics and weight in observational studies, one cannot confidently draw conclusions about causality. We use data from the Utah Population Database (UPDB) that contain body mass index (BMI) information from all drivers holding a Utah driver license to undertake a cross-sectional analysis that compares the neighborhood determinants of BMI for youth and young adults. This analysis assumes that youth have little choice in their residential location while young adults have more choice. Our analysis makes use of data on 53,476 males and 47,069 females living in Salt Lake County in 2000. We find evidence of residential selection among both males and females when BMI is the outcome. The evidence is weaker when the outcomes are overweight or obesity. We conclude that studies that ignore the role of residential selection may be overstating the causal influence of neighborhood features in altering residents’ BMI.     

Modeling Earnings Dynamics

In this paper, we use indirect inference to estimate a joint model of earnings, employment, job changes, wage rates, and work hours over a career. We use the model to address a number of important questions in labor economics, including the source of the experience profile of wages, the response of job changes to outside wage offers, and the effects of seniority on job changes. We also study the dynamic response of wage rates, hours, and earnings to various shocks, and measure the relative contributions of the shocks to the variance of earnings in a given year and over a lifetime. We find that human capital accounts for most of the growth of earnings over a career, although job seniority and job mobility also play significant roles. Unemployment shocks have a large impact on earnings in the short run, as well as a substantial long‐term effect that operates through the wage rate. Shocks associated with job changes and unemployment make a large contribution to the variance of career earnings and operate mostly through the job‐specific error components of wages and hours.     

National differences in reported subjective well-being: Why do they occur?

There are marked variations between nations in reported subjective well-being (SWB), but the explanations for this diversity have not been fully explored. It is possible that the differences are entirely due to true variability in SWB, but it is also reasonable that the differences may be due to factors related to self-report measurement such as variation across nations in whether it is desirable to say one is happy. At a substantive level, there might be differences in the norms governing the experience of emotion such that cultural differences in SWB are due to affective regulation. Pacific Rim countries (e.g., Japan, the People's Republic of China, and S. Korea) appear to have lower SWB than their material circumstances warrant, and the U.S.A. has higher SWB than is predicted based on its income per person. The genesis of these differences was explored by comparing students in S. Korea, Japan, and the People's Republic of China to students in the U.S.A., and it was concluded that: (1) The Pacific Rim subjects score lower on both happiness and life satisfaction in both absolute terms and when income is controlled, (2) There probably is not a general negative response set in the Pacific Rim which causes lower SWB, as evidenced by the fact that the Asians express dissatisfaction in some areas (e.g., education and self) but not in other areas (e.g., social relationships), (3) Artifacts are not causing the lower reported SWB, (4) The general suppression of mood in the Pacific Rim is unlikely to be the cause of SWB differences, but Chinese students do appear to avoid negative affect, (5) SWB is no less important and salient in Japan and S. Korea, but does appear to be a less central concern in China, and (6) There are different patterns of well-being depending on whether life satisfaction or hedonic balance are considered.
