The changing practice of eating: evidence from UK time diaries, 1975 and 2000

This paper examines some central themes about change in consumption behaviour through an empirical investigation of the practice of eating. It analyses patterns of food consumption in the UK using time diary data from 1975 and 2000. The practice of eating is decomposed into four component activities which are used to explore systematically the inter-relationships between social processes - such as commodification and temporal fragmentation - and ways of providing and consuming food. It charts the expansion of eating out, the degree to which it substitutes for other eating activities, and the implications of its development for social relations and the temporal organization of daily life. Analysis reveals that food consumption continues to be differentiated along established lines of social division, although the content of those divisions has changed and varies across components of the practice. Increasing commodification of the food chain is documented, but without appearing to have a corrosive impact on household organization or social relationships. While tendencies indicative of temporal fragmentation are revealed, counter-tendencies exist which suggest that the practice of eating is resilient to many forms of external pressure. Finally, the application of a practice-based analytical approach permits critical evaluation of theories of social transformation.     

The Transitional Discharge Model: comparing implementation in Canada and Scotland

Effective discharge planning is needed to facilitate clients' transition from psychiatric hospital wards to community care. Previous studies have shown that client outcomes can be improved by using a Transitional Discharge Model (TDM) that includes peer support and an extension of inpatient-practitioner relationships that are introduced prior to discharge. However, countries vary in many ways that may affect implementation of the model. This article describes some of the similarities and differences related to introducing transitional discharge in two countries: Canada and Scotland. It is important to elucidate facilitators and challenges in implementing the TDM to identify and disseminate strategies to aid implementation. Implications for future implementation of the model are also discussed.     

Unplanned sexual activity as a consequence of alcohol use: a prospective study of risk perceptions and alcohol use among college freshmen

OBJECTIVE: The authors' goal was to show how risk perceptions regarding unplanned sexual activity following alcohol use are prospectively related to subsequent alcohol consumption. PARTICIPANTS: Undergraduate students (N = 380) completed questionnaires at 2 time points during their freshman year. METHODS: In the middle of the academic year (T1), students estimated their risk of engaging in unplanned sex and reported their alcohol use during the previous term. Four months later (T2), they again reported alcohol use and indicated whether they had engaged in unplanned sex since T1. RESULTS: Students who consumed more alcohol at T1 rated their risk of unplanned sex more highly, suggesting relative accuracy. Those with higher risk perceptions consumed more alcohol at T2 (controlling for T1 use), suggesting that they maintained the high-risk behavior. Last, those who were unrealistically optimistic (ie, estimated low risk at T1 yet had unplanned sex by T2) reported greater alcohol use at T2. CONCLUSIONS: These findings highlight the role that risk perceptions regarding sexual activity may play in college students' alcohol use.     

Foreign-born emigration: A new approach and estimates based on matched CPS files

The utility of postcensal population estimates depends on the adequate measurement of four major components of demographic change: fertility, mortality, immigration, and emigration. Of the four components, emigration, especially of the foreign-born, has proved the most difficult to gauge. Without "direct" methods (i.e., methods identifying who emigrates and when), demographers have relied on indirect approaches, such as residual methods. Residual estimates, however are sensitive to inaccuracies in their constituent parts and are particularly ill-suited for measuring the emigration of recent arrivals. Here we introduce a new method for estimating foreign-born emigration that takes advantage of the sample design of the Current Population Survey (CPS): repeated interviews of persons in the same housing units over a period of 16 months. Individuals appearing in a first March Supplement to the CPS but not the next include those who died in the intervening year, those who moved within the country, and those who emigrated. We use statistical methods to estimate the proportion of emigrants among those not present in the follow-up interview. Our method produces emigration estimates that are comparable to those from residual methods in the case of longer-term residents (immigrants who arrived more than 10 years ago), but yields higher--and what appear to be more accurate--estimates for recent arrivals. Although somewhat constrained by sample size, we also generate estimates by age, sex, region of birth, and duration of residence in the United States.

多样化的现代性:全球化时代中的基督教、伊斯兰教和印度教

20世纪晚期 ,作为跨地域文化系统的世界宗教发生了影响深远的变化。本文旨在考察基督教、伊斯兰教和印度教三大宗教最近之变迁的政治性和意义。文章重点讨论那些重构宗教意义和权威的诸多力量的本质、推动归信和标准化的过程以及这些宗教重构对我们理解后期现代性本身的启发。本文认为 ,尽管现代性是多样化的 ,每个传统也都是独特的 ,但由于大众社会的全球化和晚期现代性的多元主义的缘故 ,所有这些宗教都面临着一个相似的困境     

"Good looks don’t boil the pot": Irish-Newfoundland women as fish(-producing) wives

This article explores the historical understanding of maritime womanhood in Newfoundland by examining women in fishing families along the southern Avalon Peninsula from the late eighteenth to the early twentieth centuries. It does not talk about fishwives in any popular sense of the word, for these women did not market fish; rather, they produced salt fish for market. And while middle-class observers may have perceived them as coarse and bold, within their own families and fishing communities they were seen as essential partners who contributed equally to family economies. Within a sexual division of labor that assigned vital and complementary tasks to both men and women, Newfoundland fish(-producing) wives carried out hard physical labor at public sites of production. This contributed significantly to the construction of “woman” as essential worker, which in turn had broader repercussions for their status and authority within fishing communities. The participation of fish(-producing) wives changed significantly from the 1950s onward, as the fishery moved from household production to a modernized, and discursively masculinized, industry. Yet the iconic image of the fish(-producing) wife in traditional household production remains undisrupted in the early twenty-first century.     

Innovation in user-centered skills and performance improvement for sustainable complex service systems

In order to leverage individual and organizational learning and to remain competitive in current turbulent markets it is important for employees, managers, planners and leaders to perform at high levels over time. Employee competence and skills are extremely important matters in view of the general shortage of talent and the mobility of employees with talent. Two factors emerged to have the greatest impact on the competitiveness of complex service systems: improving managerial and employee's knowledge attainment for skills, and improving the training and development of the workforce. This paper introduces the knowledge-based user-centered service design approach for sustainable skill and performance improvement in education, design and modeling of the next generation of complex service systems. The rest of the paper cover topics in human factors and sustainable business process modeling for the service industry, and illustrates the user-centered service system development cycle with the integration of systems engineering concepts in service systems. A roadmap for designing service systems of the future is discussed. The framework introduced in this paper is based on key user-centered design principles and systems engineering applications to support service competitiveness.
