Development of the ‘Travelcard’ Concept in Urban Public Transport

Traditionally, urban bus operators have collected fares in cash for each trip. Some limited mechanisation has occurred in ticket issue at stations. Partly for reasons of operating convenience, there has recently been a shift to simpler fares and prepayment, notably through the introduction of ‘Travelcards', that is, tickets or passes permitting unlimited use of the network (or zones thereof) for a defined period. These cover both all-bus systems, and bus/rail networks (such as the West Midlands PTE system). They are now used in all main British conurbations, following introduction of the London Transport bus/rail Travelcard in May 1983. The Travelcard in effect redefines the ‘product’ being sold. Instead of the public transport service being perceived as a series of separate journeys, payment is made periodically for use of the network as a whole. Cost perception is thus put on a similar basis to that for the private car. The marginal money cost for each trip becomes zero. Interchange penalties associated with re-booking are eliminated. Payment may be made by cheque or credit card, rather than cash, further changing the perception of costs. Product quality is also enhanced through speeding up of services (one-person- operated buses), and enabling the user to select the quickest and/or most convenient route in a network by removing the interchange penalty.     

Convergence and divergence of role stress experience of locally hired Japanese and non-Japanese host country staff: a qualitative study

This qualitative study examines the role stress (comprising of role ambiguity and role conflict) experienced by locally hired Japanese (LJ) and non-Japanese (NJ) staff in a sample of Japanese companies in Australia. Expatriates were also interviewed to gather information regarding the impact of cross-cultural understanding on role ambiguity and role conflict in their work relationships with LJ and NJ staff. Both LJ staff and NJ local staff experienced two types of role ambiguity, resulting from insufficient English competence and information shortage. NJ staff experienced two additional types of role ambiguity due to their lack of cultural understanding about Japan. LJ staff experienced two types of role conflict which were not experienced by NJ local staff. These were caused by their cultural understanding about Australia, and their Japanese cultural heritage and understanding of the society and organisational processes. This study shows that cultural understanding of one's host country and parent country could reduce role ambiguity. In addition, it was found that cultural understanding of one's host country and parent country results in role conflict. These findings suggest that cultural understanding could have positive and negative consequences on role stress. Theoretical and practical implications in the management of white-collar staff in overseas Japanese companies are discussed.     

Challenging The Spirit Level: Is There Really a Relationship between Inequality and Obesity?

This paper examines the proposition, set out in The Spirit Level, that inequality is associated with high levels of obesity. It reviews existing literature and uses British Household Panel Survey data to study how district‐level and regional‐level income inequality is related to obesity in the UK. This is likely to be the first study of its type that uses individual‐level data that is representative of the UK population. We find little evidence to support policies that reduce income inequality with the aim of reducing obesity levels in the UK.

心理干预复合咪达唑仑对腔镜手术心理应激反应的影响

探讨心理干预复合咪达唑仑对腹腔镜全宫切除患者术前心理应激反应的影响。择期行腹腔镜全宫切除术患者90例,ASAI或Π级,随机等分为3组：对照组（C组）,不用术前用药;咪达唑仑组（M组）,术前30 min肌注咪达唑仑0.05 mg/kg;心理干预复合咪达唑仑组（PIM组）,按照心理干预方法进行术前访视,术前30 min肌注咪达唑仑0.05 mg/kg。术晨8时及入室后即刻测定3组患者的血清ACTH、Cor、AT-Π与IL-6水平,记录术前一日访视时及入室后即刻的MAP、HR和SpO2值,并行S-AI、AVAT评分。心理干预复合咪达唑仑能明显减轻腹腔镜全宫切除术患者术前的心理负担和焦虑程度,不失为一种调控手术患者术前急性不良心理应激反应的简便易行而又切实有效的方法。     

The relationships between stress,health, and physically active leisure as a function of life‐cycle

This article examines relationships between stress, health, and participation in physically active leisure using data collected as part of the 1985 and 1990 U.S. National Health Interview Surveys (NHIS). In particular, the article analyzes: (a) the effects of life‐cycle progression (controlled for gender) on subjectively perceived stress and self‐reported health; (b) the role of physically active leisure in enhancing health or buffering adverse health outcomes of stress; and (c) the effects of selected social‐economic factors, such as education and income, on the relationships between life‐cycle, stress, health, and physically active leisure. According to our analyses: (1) stress is unevenly distributed across the life span; (2) stress‐reducing effects of physically active leisure are present among retired older people more so than in the middle‐aged life‐cycle groups; and (3) direct health‐enhancing effects of participation in physically active leisure are more evident than the buffering effects of leisure on stress‐health relationships. A critical discussion of methodological and substantive issues facing researchers interested in the relationships between leisure, stress, and health is provided.

工作生活质量的研究述评

工作生活质量是在社会技术系统理论的基础上,在员工需求发生极大变化的时候出现的新概念,并引起国内外学者的极大关注。学者们对工作生活质量的概念内涵、内容维度以及测量进行了大量研究,其中也存在不可忽视的问题：工作生活质量没有统一的概念,而且其内涵也过于空泛庞大;工作生活质量的内容维度模糊,独立性差;对工作生活质量的测度具有片面性,缺乏具有良好信度和效度的测量工具。
