This paper provides an overview of what we call ‘agroecological revolution’ in Latin America. As the expansion of agroexports and biofuels continues unfolding in Latin America and warming the planet, the concepts of food sovereignty and agroecology-based agricultural production gain increasing attention. New approaches and technologies involving the application of blended agroecological science and indigenous knowledge systems are being spearheaded by a significant number of peasants, NGOs and some government and academic institutions, and they are proving to enhance food security while conserving natural resources, and empowering local, regional and national peasant organizations and movements. An assessment of various grassroots initiatives in Latin America reveals that the application of the agroecological paradigm can bring significant environmental, economic and political benefits to small farmers and rural communities as well as urban populations in the region. The trajectory of the agroecological movements in Brazil, the Andean region, Mexico, Central America and Cuba and their potential to promote broad-based and sustainable agrarian and social change is briefly presented and examined. We argue that an emerging threefold ‘agroecological revolution’, namely, epistemological, technical and social, is creating new and unexpected changes directed at restoring local self-reliance, conserving and regenerating natural resource agrobiodiversity, producing healthy foods with low inputs, and empowering peasant organizations. These changes directly challenge neoliberal modernization policies based on agribusiness and agroexports while opening new political roads for Latin American agrarian societies.  相似文献

In different theoretical traditions, negative social conditions, attachments, and interactions shape the way individuals view the law and its agents. Although most researchers acknowledge the conceptual distinction between different legal attitudes such as legal cynicism and police legitimacy, it remains unclear to what extent these attitudes stem from the same social sources. In the current study, therefore, we evaluate the social and individual factors that influence trajectories of legal cynicism and police legitimacy using a diverse community sample of youths in Zurich, Switzerland. Latent growth curve models were employed to examine patterns of change in legal cynicism and police legitimacy between 13 and 20 years of age. The findings show that legal cynicism and police legitimacy both decline into early adulthood and exhibit high rank-stability over time. Furthermore, we find that legal cynicism is closely related to individual characteristics that reflect one's inability to recognize or abide by their internal rules. By contrast, police legitimacy is shaped by socialization influences, particularly teacher bonds and police contacts. These results indicate a need to assess the measurement and interpretation of legal cynicism critically in relation to broader legitimacy beliefs and to investigate the shared and distinct sources of these different constructs.  相似文献

In light of the growing public spending in many regions of the world, this study scrutinizes relevant determinants of core public administration expenditure at the cantonal level in Switzerland, focusing particularly on New Public Management (NPM) reforms. The empirical study comprises all 26 cantons in the period from 1993 through 2014 and uses both cross‐sectional and longitudinal analytical methods. In addition to NPM, we control for various variables related to political parties, institutions, socioeconomics and culture. The results show no clear relationship between NPM reforms and expenditure, although such reforms were often intended to cut costs. Our explanation for this finding is that NPM as a concept is rather inconsistent. Various control variables are either positively or negatively related with expenditure. All in all, our findings suggest that public expenditure is still mostly determined by politics and can only be influenced by administrative reforms within certain narrow limits.  相似文献

Genotype polymorphism studies at the 13 loci STRs included in the combined DNA index system [CODIS and PCR-based short tandem repeat loci, in: Proceedings of the Second European Symposium on Human Identification, Promega Corporation, Madison, WI, 1998, pp. 73-88; J. Forensic Sci. 46 (2001) 453] (CODIS: D3S1358, HUMvWA31, HUMFGA, D8S1179 D21S11, D18S51, D5S818, D13S317, D7S820, HUMTH01, HUMTPOX, HUMCSF1PO and D16S539) were carried out in a sample of 1429 unrelated Colombian individuals belonging to 25 different departments. As many other countries in Latino-America, Colombia shows an important admixture component, basically integrated by Amerindians, European-descendants and African-descendants. Due to the fact that only partial population analyses have been carried out in the country, the main aim of the present analysis is to establish a database of forensic interest based on the widely used CODIS systems covering the main Colombian regions.  相似文献

Eight Y-chromosome STRs were investigated in a male population sample from Córdoba region (Argentina). Complete Y-chromosomal STRs haplotypes were obtained in 100 individuals, among which 91 different haplotypes were observed. The most common haplotype was shared by 4% of the sample, while 86 haplotypes were unique. The gene diversity was 0.9875 and the discrimination capacity was 0.8600. The combined polymorphism provides a powerful discrimination tool for routine forensic applications.  相似文献

In 2016, the United States (US) government relinquished its long‐standing delegation contract with the Internet Corporation for Assignment of Names and Numbers (ICANN), a private organization that governs the technical infrastructure of the internet. This presents a puzzle as the US not only gave up a power resource, but also relinquished the possibility, as a public principal, to hold the private agent ICANN accountable. I argue that public principals have incentives to leave control in the hands of private stakeholders when a delegation contract is exposed to external pressure by powerful outside states and the probability of extensive policy changes by the privatized agent is limited. The analysis shows that the unilateral US control over ICANN was strongly challenged by other states and private actors. Instead of granting a greater role to rising powers in internet governance, the US gave up its unilateral influence after internal reforms limited the risk that an independent ICANN could deviate too far from former policies.  相似文献
