The extended enterprise-a context for manufacturing

Today's manufacturing enterprises face tremendous competitive pressures. Global competition, together with market demands for customized products delivered just in time, place tremendous pressures on manufacturers. The emerging global economy is rapidly replacing local markets. The emergence of open markets, reductions in trade barriers, and improvements in transportation and communications links have led to a situation where local competition and markets operate in the context of global standards. This open infrastructure allows manufacturers to respond to these challenges by working more closely with their suppliers and customers, and by building extended enterprises across the whole value chain. Such extended enterprises present great challenges in terms of redesigning business processes to create a competitive advantage from the linkages they include. This paper describes the manufacturing philosophies currently in vogue. Any manufacturing or related business will need to use them, albeit tailored to its own circumstances, in one form or the other, to ensure its prosperity.

The Effect of Risk Beliefs on Property Values: A Case Study of a Hazardous Waste Site1

Health risk beliefs of homeowners near a landfill site were assessed in a survey and compared to expert judgments of the health risks of living near the site. A bimodal distribution of health risk beliefs suggested sharp disagreement between the experts and at least some of the residents. Correlates of high risk beliefs included perception of odor from the site, exposure to media coverage of the problem, having children living at home, age (younger respondents more concerned), and gender (females more concerned). An aggregated neighborhood health risk belief predicted reductions in home prices even after controlling for home physical characteristics, such as size and other disamenities such as proximity to a freeway. In the 4100 homes near the site, the estimated depression in property values was estimated to total about $40.2 million before the site was closed and to be about $19.7 million after closure. Implications of these results for community conflict and for benefit-cost analysis of hazard site remediation are discussed.     

Estimating the Risks of Smoking, Air Pollution, and Passive Smoke on Acute Respiratory Conditions

Five years of the annual Health Interview Survey, conducted by the National Center for Health Statistics, are used to estimate the effects of air pollution, smoking, and environmental tobacco smoke on respiratory restrictions in activity for adults, and bed disability for children. After adjusting for several socioeconomic factors, the multiple regression estimates indicate that an independent and statistically significant association exists between these three forms of air pollution and respiratory morbidity. The comparative risks of these exposures are computed and the plausibility of the relative risks is examined by comparing the equivalent doses with actual measurements of exposure taken in the homes of smokers. The results indicate that: (1) smokers will have a 55-75% excess in days with respiratory conditions severe enough to cause reductions in normal activity; (2) a 1 microgram increase in fine particulate matter air pollution is associated with a 3% excess in acute respiratory disease; and (3) a pack-a-day smoker will increase respiratory restricted days for a nonsmoking spouse by 20% and increase the number of bed disability days for young children living in the household by 20%. The results also indicate that the estimates of the effects of secondhand smoking on children are improved when the mother's work status is known and incorporated into the exposure estimate.     

合肥848名小学生心理健康状况的调查分析

Internet presence and historically black colleges and universities: Protecting their images on the World Wide Web?

This study examines how historically black colleges and universities (HBCUs) use their home pages to present images of themselves. The home pages of 96 institutions were examined using content analysis. The findings suggest that HBCUs are not using their home pages to project a strong image. For example, less than 10% of these institutional home pages made mention of institutional rankings, and less than 20% made mention of students, athletics or faculty. The authors make suggestions for how HBCUs can better project institutional image with changes to home page content and design.

世界经济论坛与博鳌亚洲论坛运营模式对比研究

世界经济论坛与博鳌亚洲论坛都已成为共同管理国际社会事务、促进全球和地区经济发展的重要交流平台,二者同样采用会员制的形式、运用商业化的运作模式来管理事务、致力于促进经济社会发展、通过前瞻的议题设置吸引与会者的眼球;然而,由于发展背景以及当前发展程度的不同,其在运营模式上存在着一定的差异,如对会员条件限制的不同、会员结构的不同、服务保障工作主体的不同等。相比世界经济论坛,博鳌亚洲论坛商业化运作不够充分,会员结构及合作伙伴存在"中国化"偏向,对智库的重视和利用不足。博鳌亚洲论坛在坚持"三高"目标的基础上,应更加重视品牌效应,加大与国际知名、有影响力的媒体以及世界知名大学的合作,扩大知识成果的影响力;要将服务保障工作外包,以切实强化商业化运作;并加大对国外会员的发展力度,逐步弱化"中国化"倾向。     

高校体育舞蹈的价值观探索

以广东工业大学2002级至2004级本科1年级和2年级学生体育选修课中选报体育舞蹈课的学生共540人(其中男生230人,女生310人)为研究对象,通过1学期的体育舞蹈选项课教学,对他们进行问卷调查及部分生理指标的测量,发现体育舞蹈对大学生有独特的锻炼价值。主要表现在:第一,体育舞蹈具有较高的健身价值;第二,能锻炼学生美的体态和培养学生审美能力;第三,体育舞蹈是休闲、社交和娱乐活动的好选择;第四,能更好地培养学生体育活动习惯。通过分析广东高校体育舞蹈课的开设状况及存在的问题,从而提出高校体育舞蹈课改革的建议。
