中国给我全新的视角去观察世界

这是我和我太太第五次来中国,2009年2月我们还会回来,还在河北师大物理系任教。可能有人会问,为什么我和我太太退休以后要来中国？为什么在可以颐养天年的时候还要继续工作？     

Experiences of Family Carers for Persons Using Antipsychotic Medication

Given the emphasis on the use of antipsychotic medication for severe mental illness, it is important to understand family carers’ perspectives on these medications and their effects on consumers’ lives. Such information may enable providers of family interventions to better understand families’ circumstances and more effectively support them in caring for mental health service users. Snowball sampling was used to recruit 29 family carers. Family carers acknowledged the calming effect of antipsychotic medication on service users, but also noted that there were few other therapeutic benefits. Moreover, the positive influence of antipsychotic medication was in most cases largely offset by the detrimental impact of antipsychotic medication on service users’ quality of life. The family carers in rationalising the trade‐off between beneficial and adverse antipsychotic medication effects typically experienced resignation, which was often accompanied by a sense of frustration that resulted from the reliance on medication.     

An extended theory of planned behavior intervention for older adults with type 2 diabetes and cardiovascular disease

A randomized controlled trial evaluated the effectiveness of a 4-wk extended theory of planned behavior (TPB) intervention to promote regular physical activity and healthy eating among older adults diagnosed with Type 2 diabetes or cardiovascular disease (N = 183). Participants completed TPB measures of attitude, subjective norm, perceived behavioral control, and intention, as well as planning and behavior, at preintervention and 1 wk and 6 wk postintervention for each behavior. No significant time-by-condition effects emerged for healthy eating. For physical activity, significant time-by-condition effects were found for behavior, intention, planning, perceived behavioral control, and subjective norm. In particular, compared with control participants, the intervention group showed short-term improvements in physical activity and planning, with further analyses indicating that the effect of the intervention on behavior was mediated by planning. The results indicate that TPB-based interventions including planning strategies may encourage physical activity among older people with diabetes and cardiovascular disease.     

An Optimal Model for Cell Formation Decisions

This study develops an approach to cell formation decisions for cellular manufacturing layouts in group technology settings. An optimal 0–1 integer programming model is used to provide an analysis for determining which machines and parts should be assigned to cells in cellular manufacturing layouts. This approach minimizes the cost of manufacturing exceptional parts outside the cellular system, subject to machine capacity constraints. Part–machine matrices are partitioned into disconnected cells and use far fewer 0–1 variables than earlier approaches. Formulation of the model is described with a numerical example and computer solutions to realistic problems are obtained. The characteristics of computer run times, model performance, and applications of the model are discussed.     

A local analysis of ethnic group population trends and projections for the UK

Projections of the UK’s ethnic populations from 2001 to 2051 show significant future change. Groups outside the White British majority will increase in size and share, not only in core areas but throughout the country. Ethnic minorities will shift out of deprived local authorities and into less deprived ones, while the White distribution remains stable. The share of the Mixed group population in the most deprived quintile (Q5) of local authorities reduces from 26 to 19%, while its share in the least deprived quintile (Q1) increases from 22 to 29%. The corresponding shifts for Asian groups are from 25 to 18% for Q5 and from 9 to 20% for the Q1. For Black groups the Q5 quintile sees a decrease from 54 to 39% while the Q1 sees an increase from 7 to 19%. There are shifts to local authorities with lower ethnic minority concentrations by Mixed, Asian and Black populations from local authorities with high ethnic concentrations, while the White, Chinese and Other group distributions remain in 2051 as they were in 2001. So, ethnic minority groups will be less segregated from the rest of the population in 2051 than in 2001. Indices of Dissimilarity between each group and the rest of the population fall by a third over the projection period. The UK in 2051 will be a more ethnically diverse society than in 2001.     

Measuring agri-food supply chain performance and risk through a new analytical framework: a case study of New Zealand dairy

Abstract

Many researchers and practitioners have long recognized the significance of measuring performance. Although general guidelines for measuring business performance are widely available, no appropriate measurement frameworks have been developed for measuring agri-food supply chain performance. Particularly, food quality and risk-related indicators have not been well integrated into existing performance measurement systems. Our research, therefore, addresses this knowledge gap by first providing an in-depth review of extant performance measurement systems and frameworks. It then develops an analytical framework by extending the Supply Chain Operations Reference (SCOR) model which has been extensively implemented across non-food industries. The analytical framework is further validated by utilizing a case study of 50 farmers and 10 dairy companies, operating in the New Zealand dairy industry.

Our pilot testing and subsequent findings show that the individual metrics interlocked with the analytical framework are in-line with the key industrial practices adapted by the New Zealand dairy industry. In addition, the framework is flexible and scalable to evaluate and benchmark other agri-food supply chains – ranging from fresh products such as fruits and vegetables to processed foods such as canned fruits. The findings further show that the detailed information required for measuring the level-3 SCOR metrics is not easily available in the industry, as researchers need to access specific company records that may be confidential. Consequently, this study provides how agri-food supply chain managers can employ our new analytical framework in-conjunction with the SCOR model for a deeper understanding of the complicated performance measurement indicators applied in their agri-food production systems and relevant supply chains.     

Perceptions of Divorce,Closeness, Marital Attitudes,Romantic Beliefs,and Religiosity Among Emergent Adults From Divorced and Nondivorced Families

This article analyzes 401 college students’ perceptions of love, romance, parent–child closeness, and religiosity. Results revealed that college students from divorced homes were not as close with their parents and reported decreased religiosity compared to participants from nondivorced homes, and that these factors are associated with young adults’ views and expectations on romantic relationships. The work presented here provides implications for future studies in understanding the beliefs about and effects of divorce for adult children. Further, results from this study suggest that college students have different expectations regarding love, romance, and marriage based on a number of family relation factors. Implications and suggestions for future research are discussed.     

Social network engineering and race in a police academy: A longitudinal analysis

This research examined an attempt to facilitate racial integration by populating squads (i.e., workgroups) in a police academy with mixes of recruits that reflected the racial demographics of the larger cohort. This was part of the social infrastructure of the academy. Additionally, a fixed seating arrangement was considered as a second element of academy infrastructure capable of impacting racial integration. We examined the consequences of these academy components over time with regard to race by combining ethnographic accounts with social network data collected throughout the academy and using a variety of network analytic tools. These consequences with regard to race were examined as a part of social network evolution. The academy's social arrangements did accelerate the creation of social knowledge of recruits about each other and the formation of friendship ties both within and between races. However, our results point to clear limitations to such infrastructural engineering and have implications for both recruitment to police academies and dealing with race. They shed light also on processes of homophily and group composition over time and have implications for studying social networks.
