Solutions to world hunger continue to be impeded by a frame – a set of assumptions – that keeps much of humanity focusing narrowly on quantitative growth. The result is greater food production and greater hunger. Yet, across the world another way of seeing, one grounded in the relational insights of ecology, is transforming food systems in ways that both enhance flora and fauna and strengthen human relationships, enabling farmers to gain a greater voice in food production and fairer access to the food produced. 相似文献

A 5-year study of a busy ski population in Utah revealed a total at-risk period of approximately 3.5 million skier-days. While the morbidity (fractures, strains, sprains, and occasionally more severe injuries) associated with skiing is well recognized and considered by most physicians concerned to be distributed somewhat unevenly within the various skills of skiing, the authors have identified an exceedingly low mortality among the same population. Six individuals died as a result of injuries directly attributable to skiing. Three of these were considered to be advanced skiers and three were of intermediate skill. In three instances the environment was considered to play a role in the accident. Two of these victims were skiing out of control, one as a result of ice-covered snow and one as a result of speed in combination with a small jump. The third victim was crushed in an avalanche. One accident was completely unexplained, the skier having skied without apparent attempt at checking or change of course into a nonrecreational area. The two remaining skiers of intermediate skill both suffered injuries incident to falling forward with considerable force onto a relatively flat, hard snow surface. Notwithstanding the intense and sometimes prolonged exertion at relatively high altitudes (9,400 to 11,000 ft or 2.9 to 3.3 km), only one skier with a previous history of atherosclerotic heart disease died while skiing. One additional middle-aged skier with similar history died at the conclusion of the day.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

COMMENTARY ON WARSHAK'S "BLANKET RESTRICTIONS: OVERNIGHT CONTACT BETWEEN PARENTS AND YOUNG CHILDREN"

In a previous issue of this journal, Richard A. Warshak provided a summary of the developmental literature as it bears on overnight restrictions during custody arrangements. Here, the authors comment on points of agreement and disagreement with Warshak based on their reading of the theoretical and empirical literature on development. Particular reference is made to Warshak's interpretation of attachment theory and research. Points of agreement include the importance of fathers and all caregivers in the infant/young child's life as well as the overstatement in the literature of the significance of separation experiences and a "sensitive period" for attachment. Points of clear disagreement include what the author contends is an erroneous review of the empirical literature on overnights with other caregivers. Based on their review of the data on overnight visitation, the authors conclude on a more cautious note. 相似文献

This essay uses the work of Gilles Deleuze, in some detail, to argue for a new practice of criticism. Not in order to purify, refine, or generally redeem anything, but rather to encourage a focusing upon the production of fields of experience as an ethical event. As such, the piece re-problematizes what it means to raise questions, and demonstrates the underlying responsibility of doing so. 相似文献

This article investigates the influence of transnational ethnic alliances on the international interactions of states. Transnational ethnic alliances exist when both states in a dyad contain members of the same ethnic group. We argue that two types of dyads will experience higher levels of conflict than other dyads: (1) those where an advantaged minority in state A has an ethnic tie to a nonadvantaged minority in state B, and (2) those with a transnational ethnic alliance where the group in one of the states is politically mobilized. Using data from the COPDAB, Minorities at Risk, Polity II, COW, and Penn World Tables projects we find support for these contentions. 相似文献

The purpose of this research is to estimate actual body weight (in particular obesity) from the human skeleton. Known individuals (total n=187) were studied from the Bass Collection from the University of Tennessee, Knoxville. This research combines bone density, cross-sectional geometry of the femur and skeletal pathologies. Bone mineral density was calculated for the proximal femur. Three-dimensional bone surface models were created from computed tomographic scans. Cross-sectional geometry of the femur was calculated at five locations along the diaphysis. The pathologies analyzed were heel spurs, diffuse idiopathic skeletal hyperostosis (DISH), and tibial osteoarthritis. The best regression tree model included only four variables. The first split to estimate body weight was the minimum moment of inertia (I(y) ) at the distal femur, the second was midshaft width, then anteroposterior thickness at the proximal slice and the final split was the degree of DISH (SD 17.1-31.0 kg). The ability to estimate body weight from the skeleton is one more useful tool for the osteologist. 相似文献
