Abstract: A large majority of Canada's federal, provincial, territorial and local governments are now required to comply with freedom of information (foi) laws. Some critics have argued that long-standing problems of non-compliance have been aggravated during the recent period of public-sector retrenchment. However, good evidence of non-compliance has been lacking. In this study, statistical reports produced by government institutions are used to assess recent trends in the administration of the federal Access to Information Act and Ontario's Freedom of Information and Protection of Privacy Act. Limited data are also used to study British Columbia's foi law. Data suggest that policy decisions in these three jurisdictions have led to a weakening of foi laws. Three reforms are proposed: better reporting by departments and agencies on their handling of foi requests; a change in the enforcement strategy traditionally used by federal and provincial information commissioners; and a reconsideration of methods used to levy fees on individuals and organizations who make foi requests. Sommaire: Au Canada, la vaste majorité des gouvemements fédéral, provinciaux, territoriaux et locaux doivent aujourd'hui se conformer aux lois sur l'accès à l'information (laX). Selon certains, les problèmes de non-conformité, qui ne datent pas d'hier, ont été aggravés lors des récentes coupures subies par le secteur public. Les études sur la non-conformité manquent cependant. Dans le cadre de cette étude, A nous faisons appel à des statistiques produites par des institutions gouvernementales, afin d'évaluer les demières tendances de l'administration de la Loi fédérale sur l'accès à l'information ainsi que de la Loi ontarienne sur l'accès à l'information et la protection de la vie privée. On y analyse également la lai de la Colombie-Britannique en fonction de données limitées. Selon les données, les décisions en matière de politique dans ces trois juridictions auraient affaibli les lai. L'auteur propose trois réformes: les ministères et les organismes devraient mieux rendre compte de la manière dont ils traitent les demandes concernant les lai; la stratégic d'application traditionnelle que suivent les commissaires à l'information fédéraux et provinciaux devrait subir des modifications; enfin, on devrait revoir les méthodes employées pour imposer les tarifs aux particuliers ou aux organismes qui font des demandes en vertu des lai.  相似文献

The purpose of this study was to compare the effectiveness of the QIAGEN QIAamp Stool Mini Kit against a standard phenolchloroform procedure for the extraction, quantitation, and STR-typing of human nuclear DNA from human feces. Stools from six subjects were sampled by swabbing and excision. Samples extracted with the QIAamp kit gave a wide range of DNA yields, whereas those extracted by the organic method yielded no DNA. DNA was not recovered from one subject's stools by either procedure. The QIAamp extracts were amplified with the Profiler Plus and COfiler kits, and PCR inhibition was observed with DNA extracts that were further concentrated. Substitution of water or TE-4 for the QIAamp elution buffer eliminated most, if not all, of the inhibition. A modified QIAamp procedure was used to extract thirty samples, which were subjected to one of five environmental conditions. DNA was recovered from all of these samples, and typing results were obtained on 93% of the samples.  相似文献

The (unheralded) first step in many applications of automated text analysis involves selecting keywords to choose documents from a large text corpus for further study. Although all substantive results depend on this choice, researchers usually pick keywords in ad hoc ways that are far from optimal and usually biased. Most seem to think that keyword selection is easy, since they do Google searches every day, but we demonstrate that humans perform exceedingly poorly at this basic task. We offer a better approach, one that also can help with following conversations where participants rapidly innovate language to evade authorities, seek political advantage, or express creativity; generic web searching; eDiscovery; look‐alike modeling; industry and intelligence analysis; and sentiment and topic analysis. We develop a computer‐assisted (as opposed to fully automated or human‐only) statistical approach that suggests keywords from available text without needing structured data as inputs. This framing poses the statistical problem in a new way, which leads to a widely applicable algorithm. Our specific approach is based on training classifiers, extracting information from (rather than correcting) their mistakes, and summarizing results with easy‐to‐understand Boolean search strings. We illustrate how the technique works with analyses of English texts about the Boston Marathon bombings, Chinese social media posts designed to evade censorship, and others.  相似文献

Several Canadian and international scholars offer commentaries on the implications of the COVID-19 pandemic for governments and public service institutions, and fruitful directions for public administration research and practice. This second suite of commentaries considers the challenges confronting governments as a result of the COVID-19 pandemic and in the decades to come with an increasingly broad lens: the need to understand and rethink the architecture of the state given recent and future challenges awaiting governments; the need to rethink government-civil society relations and policies to deliver services for increasingly diverse citizens and communities; the need for new repertoires and sensibilities on the part of governments for recognizing, anticipating, and engaging on governance risks despite imperfect expert knowledge and public skepticism; how the COVID-19 crisis has caused us to reconceive international and sub-national borders where new “borders” are being drawn; and the need to anticipate a steady stream of crises similar to the COVID-19 pandemic arising from climate change and related challenges, and develop new national and international governance strategies for fostering population and community resilience.  相似文献

The U.S. Department of Labor's "Work Force 2000" project has identified long-term trends that will affect future employment and training policy. These include demographic trends such as a decline in the pool of young labor market entrants and an increase in women, minority, and immigrant workers; the continued shift from goods-producing industries to the service sector; and continued technological innovation in response to increased international competition. These projected changes in the labor market and workplace present a national challenge and an opportunity to tackle the longstanding problems of disadvantaged workers. Cooperative public and private programs to eliminate illiteracy and increase job skills and competencies, ease labor mobility and provide retraining, and attack underlying social problems that support the cycle of welfare dependency and unemployment are needed to provide the workforce America needs for the future.  相似文献

Agents and Structures: Two Views of Preferences, Two Views of Institutions   总被引:2,自引:0,他引:2  
Two analytical distinct approaches to the study of domestic politics have been referred to as the "new institutionalism." The fundamental difference between the two brands of institutionalism can be seen in the way they handle the relationship between "agents" and "structures.""Structure-based" approaches to institutions give ontological primacy to structures and view agents as being constituted by them. "Agency-centered" approaches view human agents as ontologically primative and view institutions as structures that are created by goal-maximizing individuals. The two approaches are compared, with special attention given to the way they treat the preferences that actors hold. I argue that contrary to arguments made by many structure-based theorists, the agency-centered approach is capable of contributing to discussions regarding the sources of actor preferences. A limited information model of the strategic interaction between workers and capitalists is used to demonstrate ways in which the agency-centered approach can begin to make preferences endogenous.  相似文献
