Road traffic injuries in general and pedestrian injuries in particular are a major public health problem in Mexico, especially in large urban areas. Analysis of mortality and road crashes at the national level was done using routine data recorded on death certificates. Fatality rates for different age groups were estimated by region for the year 2000. These data were supplemented by a cross-sectional study of pedestrian injuries in Mexico City based on death certificates information for pedestrians who lived and died in Mexico City between 1994 and 1997. Participant observation of physical spaces where crashes occurred was carried out. The spaces were filmed and in-depth interviews of survivors conducted. Road traffic crashes were responsible for approximately 17,500 deaths in Mexico during 2000. The mean age of the victims was 37 years. Mexico lost an average of 30 years of productive life for each individual who died in a traffic crash – 525,000 years in 2000. An estimated 9500 (54.3%) of all fatalities were pedestrians, and for every pedestrian death there were 13 others who sustained nonfatal injuries requiring medical care. The overall crude mortality rate for pedestrian injuries in Mexico City was 7.14 per 100,000 (CI 6.85-7.42). A concentration of deaths was observed in 10 neighborhoods at specific types of street environments. The underlying factors included dangerous crossings and the absence or inadequacy of pedestrian bridges, as well as negative perceptions of road safety by pedestrians. In conclusion, this study demonstrates the importance of elucidating the underlying contextual determinants of pedestrian injuries. 相似文献

The government's Green Paper proposes reducing state pension costs whilst encouraging private sector provision. The success of the proposed ‘stakeholder pension schemes’ depends on regulation. However, regulation can penalise those it is intended to protect. This is a sensitive issue, since stakeholder pension schemes are expected to attract financially vulnerable, lower paid, employees. Whilst the flat rate accrual of the state second pension confers some benefit, certain groups are put in a difficult position by the retention of means-tested benefits. 相似文献

Weitzman's analysis of the share economy contrasts fixed-wage and fixed-share contracts; this paper notes that neither is an optimal labor contract, rendering the comparison suspect. Given this comparison, though, share contracts may be superior to wage contracts in an economy characterized by a “macroeconomic externality,” whereby firm-level employment decisions affect the demand for other firms' goods. 相似文献

This paper explores the ingredients that stimulated the development of the biotechnology industry in the US and contrasts conditions with those in Europe. It examines relationships between established firms and new start-ups; the financing and managerial environment and the organizational environment, whereby firms were able to set up networks of alliances. Its main findings are that: 1) The funding of the medical science research base has been substantially more generous in the U.S. than Europe. It is the funding of the science base rather than of the biotechnology industry directly that has provided the foundations for start-ups to be created out of the science base. 2) It has been easier for U.S. academics to found start-ups, close to their research establishment, and to retain their academic posts and status as well as be involved in a commercial enterprise. In Europe, the scientific/academic and commercial worlds have a wider divide. 3) Start-ups have been concentrated in the therapeutics and agricultural fields, with strong scientific research inputs into their commercialization, in contrast to other sectors where downstream processing innovations have been more important, which have been undertaken in-house by the large incumbent companies. 4) Financing and managerial conditions have been significantly easier in the U.S. for start-ups, in terms of access to venture capital specialising in high technology, ability to use the stock market to raise capital, and access to people able to forge links between scientists and entrepreneurs, and to introduce managerial expertise into new companies. 5) There has been a greater facility in the U.S. than in Europe for alliances to be formed between incumbent companies and indigenous U.S. start-ups; European start-ups have not found similar backing from European incumbent companies. 相似文献

A bstract . In two of his novels , A TRAVELER FROM ALTRURIA and THROUGH THE EYE OF THE NEEDLE, William Dean Howells describes the ideal commonwealth of Australia where the production and distribution of goods and services do not occur in self-regulating markets such as those found in Western-world economies. Thus, traditional economic theories are limited in analyses of the Australian economy, and critics are hampered in their efforts to understand Howelis'Utopia. This study synthesizes Howells'criticisms of the harshness of 19th-century American capitalism as presented in the two novels and then analyzes the economic structure of Australia by using Karl Polanyi's framework for studying non-market societies. This framework includes the concepts of reciprocity, redistribution , and administered trade. 相似文献

International Approaches to Global Climate Change 总被引:2,自引:0,他引:2
This article surveys the issues involved in slowing the climatechange induced by global emissions of greenhouse gases, especiallycarbon dioxide. It addresses the possible social and economicimpacts of global warming, the elements involved in evaluatingthe pros and cons of steps to reduce those impacts, and theissues involved in engaging most of the worlds states in a cooperativeendeavor to reduce greenhouse gas emissions. It expresses doubtsabout the efficacy of a global approach based on national emissiontargets, such as those set by the 1997 Kyoto Protocol, and favorsinstead mutually agreed actions focused on a common emissiontax. It also discusses issues of compliance with an internationalagreement to reduce emissions, actions states can take in theabsence of international agreement, and contingency actionsthat might be considered if the problem proves to be more seriousthan now seems to be the case. 相似文献

Although the role of gold in the world economy has declined since the gold standard was abandoned, it remains important as a central bank reserve, a hedge against risks, a barometer of geopolitical uncertainty, and an input for jewellery. While portfolio demand for gold has been well studied, determinants of physical demand are less understood. Certain emerging‐market countries such as China and India import substantial amounts of gold, with several factors that may contribute: low financial development, need for precautionary savings and/or strong cultural valuation of gold itself. This article uses panel data on gold imports of 21 countries to examine determinants of physical demand. We find that determinants of physical demand differ from those of portfolio demand, and that they differ between the developed and developing worlds. 相似文献
