The forces associated with economic globalisation and the apparent supremacy of market forces have unleashed a range of political and social processes that have served, and were indeed designed, to enrich and empower the few at the expense of the majority. These include phenomena such as the rise in armed conflict, threats to food security, the loss of livelihoods and traditional ways of life of millions of people worldwide, the commodification of social provision, assaults on national sovereignty, and the privatisation of citizenship. However, the author argues, the most significant impact of globalisation is the 'localisation' of social and political struggle, and the emergence of new forms of international solidarity. Many NGOs have too readily succumbed to the view that globalisation in its present form is inevitable and irreversible, and have accommodated to it by trading their essential values for technical professionalism, often imported from the private sector. However, if NGOs are to assume their place as part of a transformational movement for social justice, they must rediscover and foster the values of citizen participation and develop a genuine respect for diversity. 相似文献

Abstract: This article describes the evolution of three different models in educational policy‐making in Ontario. In the late 1960s, education policy moved away from reliance on a traditional, centralized, administrative‐agency approach and gravitated towards a decentralized, asymmetrical policy interdependence that dominated until the mid‐1990s. The ndp government erected a more centralized scaffolding, with the centre undertaking a greater tutelary role vis à vis local authorities. The aim was to make more transparent the rules and standards by which local authorities, trustees and educators would operate and be held accountable. The education minister also sought to bolster local democracy by widening local parental participation in decision‐making, Since 1995, the Conservative government has erected a politicized administrative agency that has adopted a confrontational stance towards stakeholders, reduced the powers of school board trustees, decimated middle‐level professional staffing, and muffled teacher union executives. Decision‐making now seems to reside with Harris advisers and key cabinet ministers, whose stance is driven by an amalgam of neo‐liberal and neo‐conservative ideology and by voter opinion. This neo‐conservative approach differs in its embrace of a social conservatism ‐ that government maintain social order and that excessive concern for individual choice and liberty not be allowed to undermine it. Harris' social conservatism, in its K‐12 reforms, includes an embrace of regulation, hierarchy, monopoly and uniformity in the design of public policy. Sommaire: Cet article décrit l'évolution de trois modèles différents d'élaboration de politiques en matière d'éducation en Ontario. Vers la fin des anébes 1960, ces politiques d'éducation ne suivaient plus l'approche classique et centralisée caractéristique d'un organisme administratif; elles tendaient plutôt vers une interdépendance décentralisée et asymétrique, qui prédomina jusqu'au milieu des années 1990. Le gouvemement néo‐démocrate érigea une structure plus centralisée qui accordait au centre un plus grand rôle tutelaire par rapport aux autorités locales. Ceci, aux fins d'une plus grande transparence des règles et normes de fonctionnement et de redev‐abilité pour les autorités locales, les conseillers scolaires et les enseignants. Le minis‐tre de l'Éducation s'est efforcé aussi de favoriser la démocratic locale en amplifiant la participation parentale dans la prise de décisions. Depuis 1995, le gouvemement conservateur a éigé un organisme administratif politicisé qui a adopté des positions conflictuelles envers les intervenants, qui a réduit les pouvoirs des conseillers scolaires et qui a sabré dans les rangs du personnel professionnel de niveau intermédi‐aire tout en muselant les dirigeants syndicaux des enseignants. II semblerait que les décisions sont maintenant prises par les conseillers de Harris et par certains de ses ministres ‐ clé, poussés par l'opinion des électeurs et une idélogie à la fois néo‐libérale et néo‐conservatrice. Cette approche néo‐conservatrice embrasse un certain conservatisme social: le gouvemement doit maintenir l'ordre social qui ne doit pas être sapé par une trop grande préocupation concemant la liberté et les choix personnels. Le conservatisme social de Harris dans le cadre des réformes scolaires fait appel à la réglementation, à la hiérarchie, au monopole et à l'uniformité dans l'élaboration des politiques gouvemementales. 相似文献

Detection of diatoms in blood by a combination of membrane filtering and chemical digestion 总被引:2,自引:0,他引:2
An improved method for detecting diatom in blood is reported. Blood of cadavers was obtained by cardiac puncture at inquest or from the left atrium directly at autopsy. The blood was hemolyzed by sodium dodecyl sulfate (SDS) and filtered through membrane filter (47 mm in diameter and 5 microns in pore size). When the blood was putrefied, two or three pieces of membranes filters were needed because of choking membrane pore. The membrane filters were digested with fuming nitric acid and diluted with distilled water. The diluted solution was filtered through membrane filter (25 mm in diameter) again. After drying the membrane filter was immersed in oil. Diatoms on the membrane filter were clearly observed microscopically. 相似文献

Studies are reported on microbial conversion of various unsaturated fatty acids to 10-hydroxy and/or 10-oxo fatty acids by Micrococcus luteus. Four fatty acids possessing cis-9-unsaturation produced 10-hydroxy and 10-oxo fatty acid products, but three enoic acids possessing trans-9-unsaturation or double bond(s) in other than the 9-carbon position were inactive as substrates. 10-Hydroxy palmitic and stearic acids were converted to the corresponding 10-oxo fatty acids, but the 10-oxo compounds were inactive as substrates. This indicates that the metabolic sequence of cis-9-enoic fatty acid by the microbial enzyme(s) is first converted to 10-hydroxy fatty acid and then to its 10-oxo compound. 相似文献

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners. 相似文献

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures. 相似文献
