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

Borders are a unique political space, in which both sovereignty and citizenship are performed by individuals and sovereigns. Using the work of Agamben and Foucault, this article examines how decisions made at the border alienate each and every traveler crossing the frontier, not simply the ‘sans papiers’ or refugees. The governmentality at play in the border examination relies on an embedded confessionary complex and the ‘neurotic citizen’, as well as structures of identity, documentation, and data management. The state border is a permanent state of exception that clearly demonstrates the importance of biopolitics to the smooth operation of sovereign power.  相似文献

A method is described for subtyping group-specific component (Gc) derived from human bloodstains. Bloodstained cuttings were extracted in 6 M urea. The extracts were subjected to ultrathin-layer polyacrylamide gel isoelectric focusing in the pH 4.5-5.4 range. After isoelectric focusing, Gc was detected by immunofixation in cellulose acetate membranes. This method permitted the successful typing of Gc in at least four-month-old bloodstains maintained at room temperature. Bloodstains from 266 liquid blood samples of known origin were subjected to both this method and immunofixation conventional agarose gel electrophoresis with no phenotypic discrepancies observed. The Gc population data for Whites from Baltimore, Maryland, were homogeneous with white sample populations from other geographical locations within the U.S.A.; while Gc data from northern U.S.A. black sample populations appeared to be heterogeneous compared with a southern United States black sample population.  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

ABSTRACT

The questioning practices of Canadian lawyers were examined. Courtroom examinations (N?=?91) were coded for the type of utterance, the assumed purpose of the utterance, and the length of utterance. Results showed that approximately one-fifth of all utterances were classified as productive for gathering reliable information (i.e. open-ended, probing); less than one percent of all utterances were open-ended. Direct examinations contained more closed yes/no, probing, and open-ended questions. Cross-examinations contained more leading and clarification questions, and opinions. Moreover, cross- (vs. direct) examinations contained more questions with a ‘challenging the witness’ purpose. The longest utterances were opinions, followed by multiple and forced-choice questions. The longest answers were in response to open-ended questions, followed by multiple and probing questions. Implications for the truth-seeking function of the judiciary are discussed.  相似文献

Changes in the nature, scale, and speed of natural resource extraction, especially in the last two decades, have resulted in many new resource extraction areas emerging across the world. By zooming in on Indonesia, this article shows that the underlying causes and consequences of current trends are more complex than portrayed by the rancher-squatter model of frontiers that is still frequently used to explain these developments. We argue that a broadened frontier notion is necessary to address the multifaceted nature of the processes underway in contemporary Indonesian extraction areas, as well as beyond. We propose a perspective that pays explicit attention to four new developments that can be described by using the hybridization of space, time, actors, and rules, and are characterized by the fact that these processes create new perimeters in all four mentioned areas. In so doing, we challenge, broaden, and renew the meaning of frontiers.  相似文献

To identify what is needed to sustain local democracy we need a model of democratic government and an idea of the kind of social and economic context that is supportive of democracy. Local democracy requires a combination of a liberal democratic model of local government and the prerequisites of democratic stability: economic development, equality, political culture and the development of civil society. However, a number of factors, non-local as well as local, may undermine local government and local democracy, especially centralization, economic decisions, external conflicts, dependency on civil servants, the dilution of elected representation, formalistic participation, skewed representation, class conflict and official attitudes. However, democratic local government can contribute to economic development, the reduction of inequality, a democratic political culture and the development of civil society, thereby strengthening local democracy.  相似文献
