Land grabbing has gained momentum in Latin America and the Caribbean during the past decade. The phenomenon has taken different forms and character as compared to processes that occur in other regions of the world, especially Africa. It puts into question some of the assumptions in the emerging literature on land grabbing, suggesting these are too food-centered/too food crisis-centered, too land-centred, too centred on new global food regime players – China, South Korea, Gulf States and India – and too centred on Africa. There are four key mechanisms through which land grabbing in Latin American and the Caribbean has been carried out: food security initiatives, energy/fuel security ventures, other climate change mitigation strategies, and recent demands for resources from newer hubs of global capital. The hallmark of land grabbing in the region is its intra-regional character: the key investors are (Trans-)Latin American companies, often in alliance with international capital and the central state. Initial evidence suggests that recent land investments have consolidated the earlier trend away from (re)distributive land policies in most countries in the region, and are likely to result in widespread reconcentration of land and capital.  相似文献

In order to isolate, theoretically, the vital mechanisms that constrain women as citizens in Western, democratic societies, it is necessary to go beyond explanations in terms of work, into sexuality However, it is not the practice of sexual coercion which, though a serious wrong, is fundamental in subordinating women in the formally free society; it is rather the freely given—and taken—love. Furthermore, if scrutinizing pre-democratic, anti-feminist arguments can help to reveal the situation today, it is the utilitarian view of women's sexual resources, rather than arguments about sexually differentiated—and inferior female— nature , which is crucial. Secondly, the concept of 'difference', now so popular among feminist writers, is important, especially when used empirically to avoid oversimplifying unity thinking about each of the sex/gender groups. But it is not tit for conceiving the power transactions going on in the socio-sexual process Furthermore. I suppose that one of the most important tasks of feminism is to balance the weights of (different) individuality and collectivity to mutually developmental values. Thirdly, women want more than 'equal chances', something other than 'equal results', and the 'different but equally valuable' must, to be women-worthy, be defined by women themselves. In a democratic society, if women are to be full and equal members, as leaders and led, then women and men have to be openly accepted as two fundamental, interested parties in society Finally, women should not claim this citizen status first and foremost as mothers, but simply as women. i e. as female, social 'incarnate subjects'.  相似文献

The authors evaluated the usefulness of the postmortem biochemical analysis of ionic ratios in different parts of the heart and their relation to cardiac damage caused by chest trauma, as observed by anatomopathologic study. Fifty-nine 59 cases were studied, selected from routine necropsies, and samples were taken from different sites of cardiac tissue. The cause of death was trauma in 40 cases and nontraumatic causes in 19 cases. The object of this study was to analyze the levels of Na+, K+, Ca+2, Mg+2, and Zn+2 in different zones of the heart, and the relationship between intracellular and extracellular ion ratios and the different causes of death and any anatomopathologic alterations observed. The biochemical tests revealed a possible relation between the ionic values and cause of death. Alterations in cell membrane permeability and corresponding modification of the ionic ratios were produced earlier than histologic alterations, which need longer to establish themselves whether or not they follow a traumatic process.  相似文献

Allele frequencies for the nine STRs included in the AmpFlSTR Profiler Plus kit (D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317 and D7S820) were estimated from a sample of 143 unrelated individuals living in different regions of Greece.  相似文献

Nine Y-STR loci from the "minimal haplotype" included in Y-STR Haplotype Reference Databases (YHRD) together with eight additional Y-STRs (DYS437, DYS438, DYS439, DYS460, DYS461, GATA C4, GATA H4 and GATA A10) were analyzed in a sample of 101 males from Equatorial Guinea living in Madrid. Haplotype and allelic frequencies were calculated and genetic diversities were estimated for each genetic system as well as for the whole haplotype. An unexpected high frequency (6%) of intermediate alleles (13.2 and 14.2) was found in DYS385. For DYS19, two alleles were found in one sample. Another sample failed to amplify with DYS393 primers using either PowerPlex Y System (Promega Corporation) or the Y-PLEXtrade mark 12 (Reliagene, New Orleans, LA) commercial kits. Comparison between Equatorial Guinea and another African population (Mozambique; South East Coast) revealed a significant pairwise Phi(st) value between them (Phi(st)=0.03309; P=0.00000).  相似文献
