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

Parties willing to engage in cross-ethnic political cooperation are essential for the stability and democracy of ethnically divided post-conflict states. The investigation of voting in Macedonia and Bosnia, which are similarly small, impoverished, ethnically fragmented and threatened states that arose out of Yugoslavia, helps uncover factors that encourage voters to support parties willing to engage in cooperative multiethnic governance. Analysis of survey data suggests that supporters of the non-nationalist challengers in the first post-violence elections expressed both strong positive associations with the past communist system and clear negative assessments of the governing record of the incumbent nationalists, sentiments that were stronger among Macedonians than among Bosniaks. Data, however, call into question popular contentions that voters' support for non-nationalists is rooted in their social tolerance or engagement in civil society. The finding that Macedonian support for non-nationalist parties is partly due to negative voting combines with difficult domestic social and economic conditions, unfriendly neighbours and uncertain regional integration processes to suggest continuing challenges for Macedonia. 相似文献

The author analyzes Slovakia's road to democracy since the Velvet Revolution of 1989 and pays special attention to the changes
in women's position in the society. In the first section, she outlines crucial transition challenges and milestones. The second
section, central to the study, shows the last two decades in gender perspective. It starts by explaining women's lukewarm
attitudes toward gender issues both during socialism and at the threshold of the new era. The chapter discusses women's persistent
marginalization in politics, contrasting this with their active role in civil society. It cites enduring inequalities in the
labor market as well as the lingering patriarchal division of responsibilities within families and outlines changes in the
patterns of family and private life. Although women in Slovakia as well as men have become more aware of gender inequalities,
politicians have remained reluctant to embrace a “gender agenda.” A typical feature of contemporary Slovakia is the gap between
official documents promoting gender equality, approved under pressure from the European Union, and their implementation in
practice. The main actor attempting to close this gap is the pluralist sector of women's nongovernmental organizations that
has undergone remarkable growth and diversification. All these elements and processes constitute the setting in which the
2009 presidential election took place. For the first time in Slovakia's history, an incumbent president was seriously challenged
by a popular female politician. The third section of the study analyzes the gender dimensions of this unique race. 相似文献

The National Institute of Forensic Toxicology, Oslo, receives blood and urine samples from all Norwegian drivers apprehended on suspicion of driving under the influence of alcohol or drugs. In 1983 we received samples from 1446 drug-suspected drivers, out of which 445 underwent toxicological analysis. The drugs found most frequently were tetrahydrocannabinol (THC) (n = 199), diazepam (n = 166) and amphetamine (n = 102). A cautious interpretation of the data indicate that about 200 of the 445 subjects selected for toxicological analysis drove under severe influence of drugs. Because of the high percentage of submitted cases not analysed for drugs, this figure represents a minimum estimate. Compared with the results from 1978, we found a several-fold increase in detections of THC and amphetamine in 1983. The number of diazepam detections did not increase in a similar way, but we estimated that the diazepam detections would have increased 3-fold if we had analysed as frequent for this drug in 1983 as in 1978. 相似文献

Classification system of frontal sinus patterns by radiography. Its application to identification of unknown skeletal remains 总被引:4,自引:0,他引:4
Frontal sinuses of Japanese skulls were radiographically examined from the view point of identifying individuals. The system of classification of sinus was proposed, basing on the area size, the bilateral asymmetry, the superiority of side, the outline of upper borders, the partial septa and the supraorbital cells. Frontal sinus patterns could be divided into above 20,000 possible combinations by combining the class numbers in each classification item described above. The frontal sinus pattern of a given person was formulated as a code number which was determined by arranging the class numbers in each classification item as serial numbers. This identification system by the frontal sinus pattern should allow one to characterize each person. The application of this identification system to an actual criminal case was also described. 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

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

A series of fatal motorcycle accidents from a 7-year period (1977-1983) has been analyzed. Of the fatalities 30 were operators of the motorcycle, 11 pillion passengers and 8 counterparts. Of 41 operators 37% were sober at the time of accident, 66% had measurable blood alcohol concentration (BAC); 59% above 0.08%. In all cases where a pillion passenger was killed, the operator of the motorcycle had a BAC greater than 0.08%. Of the killed counterparts 2 were non-intoxicated, 2 had a BAC greater than 0.08%, and 4 were not tested. The results advocate that the law should restrict alcohol consumption by pillion passengers as well as by the motorcycle operator. Suggestions made to extend the data base needed for developing appropriate alcohol countermeasures by collecting sociodemographic data on drivers killed or seriously injured should be supported. 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
