我国人口态势与消费模式对碳排放的影响分析

本文应用STIRPAT扩展模型,考察近30年来我国人口规模、人口结构、居民消费及技术进步因素对碳排放的影响。研究发现,居民消费与人口结构变化对我国碳排放的影响已超过人口规模的单一影响力。居民消费水平提高与碳排放增长高度相关,居民消费模式变化正在成为我国碳排放的新的增长点;人口结构因素中,人口城镇化率的提高通过对化石能源消费、水泥制造及土地利用变化等的影响导致碳排放增长;人口年龄结构变化对生产的影响大于对消费的影响,其对碳排放影响的主要途径是生产领域劳动力的丰富供应;家庭户规模减小导致人均消费支出的增加及总户数消费规模的扩张,以家庭户为分析单位考察其对碳排放的影响具有较高的解释力。针对分析结果,探讨了未来我国低碳社会发展的相关应对之策。     

The implications of mean scaling for the calculation of aggregate consumer elasticities

Mean scaling is a common assumption in the estimation of aggregate consumer elasticities—in particular, expenditure elasticities, but also (implicitly) compensated price elasticities. The assumption is that each household’s income changes in the same proportion as aggregate income. If correct, that implies no bias in the use of aggregate data for estimation of expenditure elasticities. If incorrect, though, there may be substantial bias, especially if there is a high degree of inequality in the underlying income distribution, and regardless of whether one uses micro or aggregate data. We explore this issue, both theoretically and illustratively, using realistic (empirically derived) elasticity estimates coupled with relatively high and low degrees of income inequality.     

Knowledge translation efforts in child and youth mental health: a systematic review

The availability of knowledge translation strategies that have been empirically studied and proven useful is a critical prerequisite to narrowing the research-to-practice gap in child and youth mental health. Through this review the authors sought to determine the current state of scientific knowledge of the effectiveness of knowledge translation approaches in child and youth mental health by conducting a systematic review of the research evidence. The findings and quality of the 12 included studies are discussed. Future work of high methodological quality that explores a broader range of knowledge translation strategies and practitioners to which they are applied and that also attends to implementation process is recommended.     

In the Eye of the Beholder: Exploring Variations in the Perceptions of Pornography

While many studies have explored the correlates and outcomes associated with pornography use, the measurement of such use has relied heavily on self-definitions of pornography from research participants, and little is known regarding how individuals define pornography for themselves. Using a diverse sample of 2,089 individuals sampled from the online MTurk Web site, participants were asked to rate whether they felt 20 different examples of sexual media were pornography. Differences by gender, religious attendance, marital status, and pornography use patterns were explored. Results suggested significant variation across the sample in how specific examples of sexual media were perceived. In addition, response profiles significantly differed by gender, religious attendance, marital status, and use of pornography. Implications for the measurement of pornography are discussed.     

A Brief History of the Pacific Sociological Association

Founded in 1929 by Emory S. Bogardus, the PSA is the oldest regional sociological association. During its 85-year history, the association has steadily increased in membership, participation, registration and size of its annual meeting, complexity of organizational structure, and has moved from a gemeinshaft to a gesellshaft culture and to a more inclusive and democratic association. Much of this change has mirrored the growth of sociology in general and of higher educational institutions in U.S. and has been made possible essentially through the work and effort of volunteers.     

Part‐Time Employment and Problem Behaviors: Evidence From Adolescents in South Korea

This study explores the impact of adolescent part‐time work experience on problem behaviors in the South Korean context. To achieve this, propensity score matching (PSM) analyses were employed based on data from the Korean Education Employment Panel (KEEP). Results indicate that adolescents' part‐time employment during their secondary school years had significantly undesirable effects on drinking and smoking, even after preexisting differences between the two groups (i.e., those adolescents who participated in part‐time work and those who did not) were controlled by PSM. However, an insignificant difference was detected in the likelihood of running away from home. Implications of the results are discussed in terms of changes in the meanings of adolescence and of participating in part‐time work in South Korea.     

The Treadmill of Production and the Positional Economy of Consumption

The theory of the treadmill of production highlights how the constant search for economic growth leads to advanced economies being stuck on a “treadmill,” where their well‐being is not improved by economic growth, yet the impacts of this pursuit of growth causes massive, unsustainable environmental damages. In interrogating the specific driving force that keeps the irrational system of the treadmill so powerfully in place, the theory of the treadmill of production focuses on how those who control the production process, corporations, are the primary agents driving the treadmill, while also highlighting how the state and workers generally continue to provide support for the treadmill's continued reproduction. In thinking about ways to begin to unwind the treadmill, there is a clear need to explore why workers, who are also consumers and citizens, continue to support (reluctantly or not) the treadmill of production. Through an analysis of the positional economy of consumption, this paper identifies key stakes that individual consumers have in expanding their income and consumption levels through the treadmill of production, despite the widespread inefficacy of the treadmill to increase aggregate satisfaction levels. This theory of the positional economy of consumption identifies the structural forces that lock individuals into increasing their income and levels of “defensive consumption” merely to maintain their existing levels of social practices and the well‐being generated from them, thus further supporting the reproduction of the treadmill of production. La théorie de l'‘engrenage de la production’ (‘treadmill of production’) démontre en quoi la recherche constante de croissance économique enferme les économies avancées dans un ‘engrenage’, où leur bien‐être n'est pas amélioré par la croissance économique, mais où les impacts de la poursuite de la croissance se traduisent par des dommages environnementaux massifs et irréparables. En analysant les forces spécifiques qui préservent ce système avec autant de pouvoir, cette théorie insiste sur l'importance de ceux qui contrôlent le processus de production (les corporations) en tant que principaux agents appuyant cet ‘engrenage’, tout en soulignant comment, d'une manière générale, l'Etat et les travailleurs persistent à soutenir sa perpétuation. En pensant aux manières d'arrêter cet ‘engranage’, il y a un besoin évident d'étudier pourquoi les travailleurs, qui sont aussi consommateurs et citoyens, persistent à soutenir (à contrec?ur ou pas) cet ‘engrenage’ de la production. Grâce à une analyse de l'économie positionnelle de la consommation, cet article identifie les principaux intérêts qu'ont les consommateurs individuels à augmenter leurs revenus et leurs niveaux de consommation au sein de cet engrenage de la production, en dépit de son inefficacité générale à améliorer les niveaux de satisfactions agrégés. Cette théorie de l'économie positionnelle de la consommation identifie les forces structurelles qui enferment les individus dans une recherche d'augmentation de leurs revenus et de leurs niveaux de ‘consommation défensive’, seulement pour maintenir leurs niveaux actuels de pratiques sociales et le bien‐être qui en découle, contribuant ainsi à reproduire l'engrenage de la production.     

A mixed poisson–inverse-gaussian regression model

The mixed Poisson–inverse-Gaussian distribution has been used by Holla, Sankaran, Sichel, and others in univariate problems involving counts. We propose a Poisson–inverse-Gaussian regression model which can be used for regression analysis of counts. The model provides an attractive framework for incorporating random effects in Poisson regression models and in handling extra-Poisson variation. Maximum-likelihood and quasilikelihood-moment estimation is investigated and illustrated with an example involving motor-insurance claims.     

PREMARITAL SEXUAL COERCION: TREATMENT ISSUES FOR FAMILY THERAPISTS

Premarital sexual coercion is conceptualized as nonconsensual sexual activity between two persons who are not married to each other but who are involved in an intimate relationship with one another. Factors and consequences associated with premarital sexual coercion are presented. Three possible clinical scenarios are discussed, and a case example is presented to highlight the importance of several therapeutic issues, including the need for individual sessions with the victim in order to provide crisis intervention and assess her safety and willingness to continue the relationship.
