In 1997, the government of Québec instituted a low‐cost and universal childcare services program most commonly available through the “centres de la petite enfance (CPE)” (early chilldhood centers). Since 2003, this model is being slowly dismantled on account of an explosion in the number of commercial daycare centers and, since 2015, an adjustment of rates according to family revenues. This research article gathers scattered information about the childcare services offer changes in Québec to demonstrate that tearing down a section of the Québécois family policy lowers the collectivization of social reproductive work.  相似文献

Conservation biology aims at assessing the status of a population, based on information which is often incomplete. Integrated population modelling based on state‐space models appears to be a powerful and relevant way of combining into a single likelihood several types of information such as capture‐recapture data and population surveys. In this paper, the authors describe the principles of integrated population modelling and they evaluate its performance for conservation biology based on a case study, that of the black‐footed albatross, a northern Pacific albatross species suspected to be impacted by longline fishing  相似文献

Given the current crises, what means do actors implement in order to redefine the conditions for both a social contract and an economic adjustment between the producers and consumers of foodstuffs? These means can be interpreted as ways to cope with the risk of a mismatch between consumer expectations and the quality of produce in the marketplace - as new ways of assembling actors around interests that are not always stable. This quite high degree of indeterminacy, which comes into play throughout the market game, makes it necessary to better understand forms of association among actors and the arrangements that emerge as the market evolves as a function of new forms of adjustment. The actions undertaken by a group of mussel producers in France are reported. Under pressure to standardize produce, they have, nonetheless, imagined solutions for identifying produce and sorts of production so as to force the marketplace to deal with differences in quality. - Special issue on Agriculture and food.  相似文献

This article discusses the role of migration in relieving population pressures, thus making continuing development possible, using small nations in the Caribbean and the South Pacific as examples. The Caribbean islands and many Pacific islands have used out-migration to ease population pressures in this century. Surplus labor has been emerging in various Caribbean nations, independent of the international marketing problems of plantation agriculture. Rural populations alienated from plantations have had to make do on questionable and/or remote land. Population surpluses appear to originate in rural areas, but little evidence exists to suggest that those surpluses are the basis for the emigration patterns of the Caribbean islands. Emigration does not solve population problems because when ambitious, skilled workers leave their country, their actions have little to do with the existence of domestic surplus labor and their leaving may do little to facilitate domestic labor absorption. Thus, if mini-states wish to sustain their hopes of economic expansion, they must find the means to employ their surplus labor. Since mainly skilled migrants leave, their going may actually slow development and retard opportunities for labor absorption. Population movements internal to the Caribbean region may further complicate surplus labor and/or population problems. If protective entry requirements impede normal inter-island relations, they may interfere with developmental processes. In general, migration is not a feasible strategy for population control for small island nations. While temporary migration has a more positive impact than other forms of migration, problems do exist. For example, temporary migration 1) can impose significant economic costs on the source-country, and 2) may result in the source country being unable to capitalize on its initial investment in training and education of temporary migrants. In conclusion, import substitution through cooperation between small island nations, production for export where feasible, and more attention to more sophisticated international service linkages hold a better prospect for material progress than relying on the export of surplus populations.  相似文献

This study focuses on the brain drain of health care professionals and physical scientists from Argentina, using survey data on a group of 89 immigrants who are currently US residents and listed in the current edition of AMERICAN MEN AND WOMEN OF SCIENCE. Although the loss of educated people is probably more likely if their degrees are acquired abroad, even at the doctoral level, the majority of those responding held Argentine degrees. The most important motivation was to gain professional and career advancement. Although pragmatism was associated with the decision to emigrate, the political environment was also quite important. Responses indicate that the losses of scientific personnel which have occurred in the past may be irreversible. Most of the respondents have become US citizens and now have families in that country. However, many respondents still have family, friends, or professional associations in Argentina. Some subtleties bear mention. The retreat of the generals has not removed all political factors from the problem list. Now scientific and professional activities must be de-politicized. The government must take explicit steps to ensure that academic and scientific positions are awarded on the basis of expertise. The evidence suggests that educational considerations are far less important as a causal element in the brain drain from Argentina than is the case in many Third World countries.  相似文献

An analysis of the brain drain from the Andean countries of Bolivia, Chile, Colombia, Ecuador, and Peru to the United States is presented. The data are from a survey of 62 persons from those countries who are currently residing in the United States and are listed in the current edition of "American Men and Women of Science". The reasons why they left their country of origin and are staying in the United States are considered. (summary in FRE, SPA)  相似文献

The 2003 Heat Wave in France: Dangerous Climate Change Here and Now   总被引:14,自引:0,他引:14  
In an analysis of the French episode of heat wave in 2003, this article highlights how heat wave dangers result from the intricate association of natural and social factors. Unusually high temperatures, as well as socioeconomic vulnerability, along with social attenuation of hazards, in a general context where the anthropogenic contribution to climate change is becoming more plausible, led to an excess of 14,947 deaths in France, between August 4 and 18, 2003. The greatest increase in mortality was due to causes directly attributable to heat: dehydration, hyperthermia, heat stroke. In addition to age and gender, combinatorial factors included preexisting disease, medication, urban residence, isolation, poverty, and, probably, air pollution. Although diversely impacted or reported, many parts of Europe suffered human and other losses, such as farming and forestry through drought and fires. Summer 2003 was the hottest in Europe since 1500, very likely due in part to anthropogenic climate change. The French experience confirms research establishing that heat waves are a major mortal risk, number one among so-called natural hazards in postindustrial societies. Yet France had no policy in place, as if dangerous climate were restricted to a distant or uncertain future of climate change, or to preindustrial countries. We analyze the heat wave's profile as a strongly attenuated risk in the French context, as well as the causes and the effects of its sudden shift into amplification. Research and preparedness needs are highlighted.  相似文献

A growing awareness of child sexual exploitation (CSE) in the United Kingdom and throughout the world has prompted human service and legal/policy professionals to seek ways of engaging young people experiencing sexual exploitation, although much remains unknown regarding effective practice, and whether or not current knowledge regarding best practices with young people can be expanded to address CSE. This paper considers how principles of harm reduction, a public health approach widely used to engage adults and young people in help‐seeking behaviours, can be considered as part of a children's rights‐centred approach to policy and practice with young people experiencing CSE.  相似文献
