A mobile and fast, semi-automatic ultrasound (US) system was developed for facial soft tissue depth registration. The system consists of an A-Scan ultrasound device connected to a portable PC with interfacing and controlling software. For 52 cephalometric landmarks, the system was tested for repeatability and accuracy by evaluating intra-observer agreement and comparing ultrasound and CT-scan results on 12 subjects planned for craniofacial surgery, respectively. A paired t-test evaluating repeatability of the ultrasound measurements showed 5.7% (n = 3) of the landmarks being significantly different (p < 0.01). US and CT-scan results showed significant differences (p < 0.01) using a Wilcoxon signed rank test analysis for 11.5% (n = 6) of the landmarks. This is attributed to a difference in the volunteer's head position between lying (CT) and sitting (US). Based on these tests, we conclude that the proposed registration system and measurement protocol allows relatively fast (52 landmarks/20 min), non-invasive, repeatable and accurate acquisition of facial soft tissue depth measurements.  相似文献

The recent House of Lords decision in Quintavalle v Human Fertilisation and Embryology Authority has raised difficult and complex issues regarding the extent to which embryo selection and reproductive technology can be used as a means of rectifying genetic disorders and treating critically ill children. This comment outlines the facts of Quintavalle and explores how the House of Lords approached the legal, ethical and policy issues that arose out of the Human Fertilisation and Embryology Authority's (UK) decision to allow reproductive and embryo technology to be used to produce a 'saviour sibling' whose tissue could be used to save the life of a critically ill child. Particular attention will be given to the implications of the decision in Quintavalle for Australian family and medical law and policy. As part of this focus, the comment explores the current Australian legislative and policy framework regarding the use of genetic and reproductive technology as a mechanism through which to assist critically ill siblings. It is argued that the present Australian framework would appear to impose significant limits on the medical uses of genetic technology and, in this context, would seem to reflect many of the principles that were articulated by the House of Lords in Quintavalle.  相似文献

Three experiments were conducted to explore whether children's recall of an occurrence of a repeated event could be improved by encouraging them to consider various details that occurred across a series of events prior to making a judgement about which details were included in the target (to-be-recalled) occurrence. Experiment 1 explored whether children's recall of the target occurrence was better after the interviewer presented all the items from the series prior to the child identifying the final item. Experiment 2 explored whether having the children generate all the items facilitated their subsequent recall of the target occurrence. Finally, Experiment 3 directly compared the effectiveness of the above 2 procedures. Regardless of the children's age, the retention interval, or the type of item, children's capacity to identify which details were included in a target occurrence was enhanced when they were initially provided with all the possible details from the series of events. However, without relying on the interviewer to generate the options, the benefit of the technique was directly contingent on the children's ability to generate content details; this was a distinct source of difficulty for the children. Indeed, having children generate options had no beneficial effect on decisions about the temporal position of items unless performance was made conditional on the children's ability to remember the relevant details in the first place. The implications of the findings for the legal setting and for future research are discussed.  相似文献

The analysis of fatty acids from common vegetable oils was investigated for application to forensic casework. A base-catalyzed transesterification of the fatty acids to fatty acid methyl esters using tetramethylammonium hydroxide was simple, rapid, straightforward and inexpensive. Canola, corn, olive, peanut, safflower, soybean and sunflower oils were able to be classified based on their fatty acid methyl ester profiles. Using gas chromatography-mass spectrometry, the detection limits for canola, corn, olive, peanut and safflower oils were determined to be 0.4 mg/mL or less and 0.2 mg/mL or less for soybean and sunflower oils.  相似文献

Sommaire: L'analyse détaillée des rapports d'autorité entre les acteurs de l'arène politique qui impliquent les différentes instances décisionnelles a contribuéà la compréhension des stratégies et des objectifs poursuivis par chacun des acteurs en présence. En outre, la gestion de la crise du verglas a permis de rendre compte de diverses stratégies, notamment celles qui ont conduit les autorités municipales à exercer davantage leur rôle de porte-parole. Des dew rôles du décideur politique, soit dirigeant et porte-parole, celui de porte-parole est le plus manifestement politique car il participe directement au processus de la médiation et de la régulation. En cela, il contribue à une fonction de repréntation de la collectivité. Cette fonction de porteparole des décideurs municipaux a été soutenue, voire favorisée par la centralisation déisionnelle de la gestion de la crise au niveau national, parfois au détriment du rôle de dirigeant des autorités municipales. Le cas de la crise de verglas participe à une tendance générale du système de régulation des rapports entre les élus des différentes instances décisionnelles et il s'inscrit comme mode de contrôle et d'intervention du pouvoir national sur les pouvoirs qui lui sont subordonnés. L'appropriation des opérations par les acteurs politiques de la gouverne nationale s'est réalisée par l'implantation d'un dispositif organisationnel visant la substitution du modèle fonctionnel par un modèlead hoc centralisé. Le modèlead hoc a permis d'intégrer les liens d'autorité habituels et a conduit par la suite à l'établissement de ce que nous avons désigné le modèle effectif.Le bon fonctionnement du modèle effectif exige l'absence d'acteurs potentiellement en situation d'opposition. Les relations entre les acteurs engagés dans les opérations associées à la gestion du sinistre ont dés lors été soumises aux règles et intérêts des acteurs politiques de la gouveme nationale. Abstract: The detailed analysis of the authority relationships between players in the policy arena and the various decision-makers contributed to understanding the strategies and objectives of each player. Moreover, management of the ice storm crisis highlighted various strategies, including those that led municipal authorities to expand their spokesperson role. The role of the spokesperson is more clearly political because it plays a direct part in the mediation and regulatory process, thus contributing to a community representation function. This spokesperson function of municipal decision-makers was supported and even fostered by the centralization of decisions while managing the crisis at the national level (i.e., Quebec), sometimes to the detriment of the leadership role of municipal authorities. The ice storm case is part of an overall trend within the system for regulating the relationships between elected representatives at the various decision-making levels, and it is also a means of national control and intervention over the powers subordinated to the national authority. National policy-makers operated by implementing an organizational system substituting a centralized, ad hoc model for the functional model. Using the ad hoc model, the usual authority linkages were integrated, subsequently leading to the setup of the effective model. For smooth operation, the effective model requires that there be no players holding diametrically opposite positions. The relationships between the players in crisis management operations were thus governed by the rules and interests of national policy-makers.  相似文献

Abstract: In the next few years, Quebec's public service will be facing a problem of labour retention. With many public-service employees due to retire, the number of young people old enough to enter the job market will likely not be sufficient to fill the voids created by their departure. At the request of the Treasury Board Secretariat, we conducted a survey of young public servants in an effort to determine whether they were planning to leave the public service in the next few years and, if so, the reasons for their decision. This study presents the results of that survey. We noted a certain dissatisfaction surrounding issues related to working conditions. However, we also found that a good number of young public servants identify with the objectives of the public service. The government can certainly gain important benefits from this in order to position itself as an “employer of choice.”  相似文献

This article uses a purposive method of interpretation to suggest solutions to various questions raised in the application of the National Minimum Wage Act (NMWA). The article first considers the goals of minimum wage laws (and the NMWA in particular) by putting forward the justifications for such laws and addressing critiques. It is argued that the minimum wage is best understood as a mechanism for redistribution of resources and ensuring respect for the human dignity of workers. Building on this articulation of goals, the article then proceeds to consider which group of workers are included within the scope of the NMWA (interpreting terms such as 'worker', 'voluntary workers', apprentices and trainees); what are considered working hours for the purpose of the Act (focusing on cases of work/sleep combinations); and what constitutes part of the wage (focusing on tips, attendance allowances and deductions for accommodations).  相似文献

Sommaire: Cet article s'interroge sur les formes de gouvernance qui caractérisent le secteur communautaire en s'appuyant sur l'étude de deux cas de partenariats locaux initiés par l'organisme Québec en forme (QEF) dans les régions de l'Outaouais et de la Mauricie. La participation croissante des organismes communautaires à la prestation des services publics met en relief l'importance de la collaboration et du partenariat interorganisationnels dans le cadre d'une gouvernance plus horizontale. L'article présente certaines difficultés posées par la construction d'une telle gouvernance dans le secteur communautaire. Le poids des structures de pouvoir traditionnelles, de même que les innovations proposées dans la littérature sur la gouvernance et l'horizontalité (élargissement des partenariats, développement de nouveaux objectifs partagés, etc.), ont beaucoup de difficultéà prendre assise dans la pratique communautaire. Abstract: This article examines the forms of governance that characterize the community sector, referring to two case studies of local partnerships initiated by the group “Québec en forme” (QEF) in the Outaouais and Mauricie regions. The increasing participation of community organizations in the delivery of public services highlights the importance of cross‐jurisdictional cooperation and partnerships within the framework of a more horizontal governance. The article presents some of the challenges surrounding governance construction in the community sector. The weight of traditional power structures, as well as the innovations proposed in the literature on governance and the implementation of a horizontal approach (securing broader partnerships, developing new shared objectives, etc.), are not easily adopted in community practice.  相似文献
