公共娱乐场所从业人员生殖健康服务的调查分析--以长沙市为例

本研究探讨计划生育服务网络为公共娱乐场所提供生殖健康服务的干预模式。分析了基线调查数据。娱乐场所从业人员是一个高流动性的年轻群体,生殖保健知识欠缺,对性病艾滋病预防的认识仍有误区;他们的性观念开放,部分从业人员涉及商业性行为,已经成为传播性病艾滋病的高风险桥梁人群。基线调查为进一步开展生殖健康服务找到了干预重点和适宜的工作方式。     

New Zealand secondary technology teachers’ perceptions: “technological” or “technical” thinking?

Technology education in the New Zealand context has seen significant change since it’s inception as a technical subject. The changing nature of the subject in New Zealand secondary schools is influenced by some teachers’ preoccupation with the making of quality product outcomes, rather than their enactment of the curriculum, which conceptualises a wider remit. Research into the perceptions of technology teachers’ interpretation and enactment of the curriculum suggests that to enable change, teachers need to adopt a form of “technological thinking”, in support of their “technical thinking”. Technological thinking is a notion presented to support teachers to explore a range of differing pedagogical approaches and learning outcomes, reflective of the intent of the New Zealand curriculum, which aims to foster learning environments that are innovative and responsive to students’ social and academic needs.     

The effects of product knowledge on the evaluation of warranteed brands

This study explores the effects of consumer knowledge on respondents' evaluations of both known and unknown brands that include either a 2-year or a 20-year warranty. Both experts and nonexperts evaluated warranty as more important than brand name in their product quality decision. Warranty length was positively correlated with product quality perceptions for both known and unknown brands. With the unknown brand, nonexperts perceived significant improvement in product quality when the warranty length was increased from 2 to 20 years. For the known brand, nonexperts perceived little difference in quality for the two warranty lengths. Experts indicated no significant differences in perceived quality, given the four brand/warranty-length conditions. The results indicate that warranty length is most heavily weighted as a cue to product quality when consumers are not highly knowledgeable, and the brand name is not well known. © 1996 John Wiley & Sons, Inc.     

Backpackers in Hong Kong – motivations,preferences and contribution to sustainable tourism

This paper examines the backpacker market in Hong Kong, in terms of profile, motivation, preferences, and contribution to sustainable tourism development. The purpose is to provide an understanding of this market to help in marketing and promoting services and products that meet backpackers’ needs as part of expanding Hong Kong’s target market. Currently, Hong Kong relies on tourists from mainland China and recent reports reveal the issue of social conflicts between mainland tourists and Hong Kong residents. Based on a survey of backpackers in youth hostels and hiking trails in Hong Kong, this study revealed that backpackers are pushed by the search for new ideas and pulled by the uniquefood culture of Hong Kong, preferring to experience such a unique food culture in a traditional setting. Moreover, they are less likely to spend on international brands in Hong Kong as part of promoting sustainable tourism development.     

Contesting authentic practice and ethical authority in adventure tourism

This paper examines the discourses of authenticity and ethics employed by adventure tourists regarding the use of the natural environment. In one case, full-time traveling rock climbers use their dedication to the sport and annual visits to the Red River Gorge as evidence for their authoritative voice on ethical climbing practice. While they identify the growing numbers of leisure climbers as a problem for sustainability, many also take up temporary employment as guides and are directly involved in the introduction of new climbers to the area. In another case, two groups of wilderness enthusiasts – “ADK 46ers” and “Summit Stewards” – lament the environmental and social impacts of other recreational users in the Adirondack Park. Despite being visitors themselves, Summit Stewards and 46ers use their sense of place and knowledge of Adirondack history and ecology to substantiate their authority as purveyors of ethical practice. In both cases, senses of responsibility are inspired by senses of place, but are articulated through notions of authenticity and used as justification for ethical authority. While validating their presence in these outdoor spaces, the use of such rhetoric also minimizes their own impacts yielding further tensions among user groups.     

But are they Meritorious? Genetic Productivity Gains under Plant Intellectual Property Rights

The objective of this paper is to evaluate the effect of Plant Variety Protection (PVP) on the productive merit/yield increases of US seed varieties. As an example, we use wheat varieties, which are and have been available as both protected and unprotected under PVP from both the public and private sectors. We find evidence that PVP has contributed to the genetic improvement of wheat, using varietal trial data from Washington State. As the private open‐pollinated varieties exist only because of PVP and are higher yielding, these results indicate a clear public benefit from PVP.     

Country of origin labeling for complex supply chains: the case for labeling the location of different supply chain links

We investigate the value of a country of origin label (COOL) that separately identifies the geographic location of different stages in a food product's supply chain. We estimate the willingness‐to‐pay (WTP) of U.S. consumers for a packaged cereal product where the key grain ingredient may be grown in one country and processed in a second country (multicountry supply chain) and compare it to equivalent products that have both stages located in a single country. We find consumer WTP for products with single‐country and multicountry supply chains are statistically different, meaning that simplifying a multicountry label by listing only the country where the ingredients are grown or only the country where the ingredients are processed can result in different consumer values. We also find that for countries with a poor quality reputation, consumers respond more negatively when that country has the “last touch” than when that country's involvement is limited to upstream supply chain links.     

Supporting ALARP decision making by cost benefit analysis and multiattribute utility theory

Current guidance in the UK and elsewhere indicate upper and target risk limits for the operation of nuclear plant in terms of individual risk per annum. ‘As low as reasonably practicable’ (ALARP) arguments are used to justify the acceptance or rejection of policies that lead to risk changes between these limits. The suitability of cost‐benefit analysis (CBA) and multiattribute utility theory (MAUT) are assessed for performing ALARP (‘as low as reasonably possible’) assessments, in particular within the nuclear industry. Four problems stand out in current CBA applications to ALARP, concerning the determination of prices of safety gains or detriments, the valuation of group and individual risk, calculations using ‘disproportionality’, and the use of discounting to trade‐off risks through time. This last point has received less attention in the past but is important because of the growing interest in risk‐informed regulation in which policies extend over several timeframes and distribute the risk unevenly over these, or in policies that lead to a nonuniform risk within a single timeframe (such as maintenance policies). The problems associated with giving quantitative support to such decisions are discussed. It is argued that multiattribute utility methods (MAUT) provide an alternative methodology to CBA which enable the four problems described above to be addressed in a more satisfactory way. Through sensitivity analysis MAUT can address the perceptions of all stakeholder groups, facilitating constructive discussion and elucidating the key points of disagreement. It is also argued that by being explicitly subjective it provides an open, auditable and clear analysis in contrast to the illusory objectivity of CBA. CBA seeks to justify a decision by using a common basis for weights (prices), while MAUT recognizes that different parties may want to give different valuations. It then allows the analyst to explore the ways in which different parties might (or might not) come to the same conclusion even when weighting items differently.
