Abstract: The history of legislation to control aggregate mining reflects a power struggle between provincial and municipal interests. A content analysis of 140 Ontario Municipal Board (omb) hearings was assessed for a twenty‐five‐year period to evaluate the conflict between provincial and municipal governments and to document the role of legislation and policy in the resolution of the disputes. This article discusses the trend of successive Ontario governments to move the municipalities out of the core of the policy network dedicated to aggregate extraction. This is a result of the province's need to assure its greater autonomy in the industry in order to guarantee adequate stocks for future development. The province's autonomy allows a greater consideration to the industry and somewhat less consideration to the environmental impacts of aggregate mining. The article shows that there has been an evolution in the policy network from a “captured network” to a more “pluralist network.” Pushing the municipalities to the periphery through strong legislation has allowed the province to undermine the strength of the municipality to protect local interests primarily concerned with reducing the amount and impact of mining taking place near residential developments. Sommaire: L'histoire de l'élaboration de lois dans le but de contrôler l'extraction d'agrégats reflète une lutte de pouvoir entre les intérêts provinciaux et municipaux. Une analyse de 140 audiences de la Commission des affaires municipales de I'Ontario (camo) couvrant plus de vingt‐cinq ans a été réalisée afin d'évaluer le con‐flit survenu entre les gouvemements provincial et municipaux et de documenter le rô1e des lois et des politiques dans la résolution de conflits. Le présent article examine comment les gouvemements qui se sont succédés en Ontario ont eu tendance àéloigner les municipalités du ceur du réseau de politiques en matière d'extraction d'agrégats. Cela vient du fait que la province doive faire preuve d'une plus grande autonomie à 1'égard du rô1e de I'industrie afin que la province puisse garantir la disponibilité de stocks adéquats pour la mise en valeur future. L'autonomie de la province a permis d'accorder un plus grand rô1e à l'industrie et quelque peu moins d'importance aux incidences environnementales de l'exploitation des agrégats. Toutefois, l'article montre qu'il y a eu me évolution dans le réseau des responsables de politiques, celui‐ci étant passé d'un réseau de la capture à un réseau plus pluraliste. En repoussant les municipalités à la périphérie par le biais de lois puis‐santes, la province a pu réduire leur capacité de protéger les intérêts locaux qui visent principalement à réduire l'importance et l'incidence dc I'cxploitation minière a proximité des lotissements résidentiels.  相似文献

Dental development can be used to estimate age for forensic purposes. However, most of the currently available methods are less reliable for the Indonesian population due to population variability. This study presents a new method and evaluates other methods that utilize dental development to estimate the age of Indonesian people. Panoramic radiographs of 304 young Indonesian people aged 5–23 years old were analysed for deciduous tooth root resorption, permanent tooth calcification, and eruption. The extent of tooth root resorption was determined based on AlQahtani’s modified Moorrees et al. method. Tooth calcification was classified based on a modified Demirjian et al. method. Tooth eruption was evaluated based on AlQahtani’s modified Bengston system. The sequence of tooth root resorption, and permanent tooth calcification and eruption were grouped into 19 age categories (from 5–23 years old) in an atlas. The differences between males and females, between maxillary and mandibular teeth, and between right and left teeth were also analysed. There were minimal significant differences of tooth development between males and females, and between the right and left teeth (P > 0.05), while the maxillary and mandibular dental development was significantly different (P < 0.05). The newly developed atlas showed the development of the right side of maxillary and mandibular tooth of combined sex of Indonesian population. Another 34 panoramic radiographs of known-age and sex individuals from Indonesia were assessed using the newly developed Atlas of Dental Development in the Indonesian Population, Ubelaker’s Dental Development Chart, The London Atlas of Human Tooth Development and Eruption by AlQahtani, and the Age Estimation Guide-Modern Australia population by Blenkin-Taylor. Accuracy was assessed by comparing estimated age to actual chronological age using the Bland-Altmand test. Results show that the smallest range of error was found in the Atlas of Dental Development in the Indonesian Population (−0.969 to 1.210 years), followed by The London Atlas of Human Tooth Development and Eruption by AlQahtani (−2.013 to 1.990 years), the Age Estimation Guide-Modern Australia population by Blenkin-Taylor (−2.495 to 2.598 years), and the Dental Development Chart by Ubelaker (−2.960 to 3.289 years). These findings show that the Atlas of Dental Development constructed in this study performs better than the other three methods and presents greater accuracy of age estimation in the Indonesian population.

Key points

  • Dental development such as deciduous tooth root resorption, permanent tooth calcification, and tooth eruption can be used to estimate age for forensic purposes.
  • The development of the teeth are influenced by genetic, ethnicity, and sex, therefore an age estimation method must be constructed based on the same population.
  • There were minimal significant differences in tooth development between male and female, and between right and left teeth, but there was significant difference between maxillary and mandibular teeth.
  • The Atlas of Dental Development in the Indonesian Population constructed in this study allowed more accurate age estimation of the Indonesian sample than the other methods tested.

This article describes the current state and range of information protection in the growing number of states and Canadian provinces that employ parenting coordination in an effort to reduce repeat custody litigation. The predominant approach—in which what is revealed during the process is not confidential—is analyzed in terms of its compatibility with the parenting coordinator's multiple tasks of educating parents, seeking to facilitate agreements, and, if necessary, providing the court with a report, a recommended decision, or an arbitrated result. Using a case scenario with multiple parts, the article then examines such confidentiality schemes in practice by providing an action‐oriented series of questions that illustrate how much of this topic must be resolved through a parenting coordinator's exercise of discretion in the absence of rule clarity. The article then raises a number of policy questions about whether current parenting coordination confidentiality norms strike the optimal or even the correct balance on information protection and concludes by identifying several policy options that might address these questions.  相似文献

Suicide is a leading cause of death among adolescents, many of whom fail to disclose suicide concerns to adults who might help. This study examined patterns and predictors of help-seeking behavior among adolescents who seriously considered suicide in the past year. 2,737 students (50.9?% female, 46.9?% male; racial distribution 79.5?% Caucasian, 11.9?% Hispanic/Latino, and 3.6?% Black/African-American) from 12 high schools in rural/underserviced communities were surveyed to assess serious suicide ideation (SI) in the past year, disclosure of SI to adults and peers, attempts to get help, attitudes about help-seeking, perceptions of school engagement, and coping support. Help-seeking was defined as both disclosing SI to an adult and perceiving oneself as seeking help. The relationship between adolescents' help-seeking disclosure and (1) help-seeking attitudes and (2) perceptions of social resources was examined among suicidal help-seeking youth, suicidal non-help-seeking youth, and non-suicidal youth. Of the 381 (14?%) students reporting SI, only 23?% told an adult, 29?% sought adult help, and 15?% did both. Suicidal help-seekers were similar to non-suicidal peers on all measures of help-seeking attitudes and social environment perceptions. Positive attitudes about help-seeking from adults at school, perceptions that adults would respond to suicide concerns, willingness to overcome peer secrecy requests, and greater coping support and engagement with the school were associated with students' increased disclosure of SI and help-seeking. This study supports prevention strategies that change student norms, attitudes and social environments to promote help-seeking among adolescents with SI. Promising intervention targets include increasing students' perceptions of the availability and capability of adults to help them, and strengthening students' understanding of how existing resources can help them cope.  相似文献

This article examines to what extent transparency is a condition for the creation of public value. Transparency is usually narrowly defined as a tool for external stakeholders to monitor the internal workings of an organization, but public value management positions transparency as a broader instrument for actively engaging stakeholders. We investigate empirically whether transparency is indeed necessary to create public value, distinguishing between transparency about operational capacity, authorizing environment, and value proposition. We find that more transparent public organizations achieved higher public value scores, especially if they disclosed information about the design and dynamics of their authorizing environment.  相似文献

In this study, we consider the efficacy of a relatively new and widely accepted certification system for teachers established by the National Board for Professional Teaching Standards (NBPTS). We utilize an extensive database covering the universe of teachers and students in Florida for a four‐year span to determine the relationship between NBPTS certification and the impact of teachers on student test scores from both low‐stakes and high‐stakes exams. Contrary to some previous studies, we find evidence that NBPTS certification provides a positive signal of a teacher's contribution to student achievement only in a few isolated cases. However, our results do reinforce evidence from previous research that the process of becoming NBPTS certified does not increase teacher productivity. © 2009 by the Association for Public Policy Analysis and Management.  相似文献

The events of 9/11 have influenced policy making in public administration. The Homeland Security Act of 2002, which created the Department of Homeland Security, contained language that empowered the secretary of homeland security and the director of the Office of Personnel Management to establish a personnel management system outside the normal provisions of the federal civil service. Why did civil service reform succeed as part of this legislation when previous attempts at large‐scale reform had failed? A case analysis of the enactment of civil service reform in the Homeland Security Act points to theories of policy emergence and certain models of presidential and congressional policy making. In this case, civil service reform became associated with national security instead of management reform. An assessment of the rhetorical arguments used to frame this policy image offers a powerful explanation for the adoption of the personnel management reforms in the Homeland Security Act. This case has implications for understanding how policy makers might approach future management reform agendas.  相似文献

Abstract: That there is some public responsibility for toxic waste management is a point widely taken for granted. However, there has been controversy over whether toxic waste management should become the responsibility primarily of a public corporation. Proposals for a public corporation to assume such responsibility have been advanced in Canada at the provincial level with widely varying outcomes. Through a comparison of three cases – British Columbia, Alberta, and Ontario – this article examines the salient issues in this policy debate and questions the prevailing mode of problem definition in order to propose a contrasting approach to public responsibility. Sommaire: On s'accorde généralement pour dire qu'il existe une certaine responsabilité publique face à la gestion des déchets toxiques. Par contre, la question de savoir si la responsabilité de gérer ces déchets devrait incomber surtout à une société d'État a fait, elle, l'objet de controverses. Dans les provinces où on a proposé qu'une société d'État prenne en charge cette responsabilité les résultats ont été fort variés. En comparant trois cas, ceux de la Colombie-Britannique, de l'Alberta et de l'Ontario, cet article examine les principales questions de ce débat et met en doute la façon actuelle de définir le problème, afin de proposer une approche différente en ce qui concerne la responsabilité publique.  相似文献

Adolescent girls aged 12 through 16 years, identified as either educable mentally retarded, behaviorally disordered, learning disabled, or nonhandicapped, were rated by their teachers on the Behavior Problem Checklist. Analysis of these ratings revealed significant differences for pupil category, Behavior Problem Checklist dimension, and category-by-dimension interaction. Behaviorally disordered students showed a greater degree of maladjustment than the retarded and nonhandicapped students on all four checklist dimensions, and exceeded the learning disabled on three dimensions (not Personality Problem). Implications for further research and special educational practices based on the present findings are discussed.Received Ed.D. from University of Virginia.
