This paper’s purpose is to extensively review the historical understanding of conscience and the current juridical interpretation of freedom of conscience under section 2(a) of the Canadian Charter of Rights and Freedoms (1982). It then briefly notes that given the challenge faced by Ontario’s Catholic schools in providing for inclusionary policies for gay students—in particular the provision of Gay Straight Alliance clubs, and the potential claim by Catholics to freedom of conscience under the Charter—it appears that litigation is inevitable. 相似文献

A recent “third wave” of neural network (NN) approaches now delivers state-of-the-art performance in many machine learning tasks, spanning speech recognition, computer vision, and natural language processing. Because these modern NNs often comprise multiple interconnected layers, work in this area is often referred to as deep learning. Recent years have witnessed an explosive growth of research into NN-based approaches to information retrieval (IR). A significant body of work has now been created. In this paper, we survey the current landscape of Neural IR research, paying special attention to the use of learned distributed representations of textual units. We highlight the successes of neural IR thus far, catalog obstacles to its wider adoption, and suggest potentially promising directions for future research. 相似文献

This article presents results of a study of library-related posts on Yik Yak, a former social media app, and questions received via more traditional library-maintained virtual reference service platforms—namely, chat/instant messaging, SMS/text messaging, email, and LibAnswers' Query Spy—at College of Charleston's Addlestone Library. Based on an analysis of the results, suggestions are made for using social media tools similar to Yik Yak as a tool for interacting with patrons in academic library settings, specifically as a means to gather feedback about the library and to provide basic reference services. 相似文献

The authors review how access to historical aerial photograph collections has evolved in response to technological developments and addresses areas for further advancement, with a particular emphasis on developing, preserving, and sustaining online collections. The authors focus specifically on the areas of metadata, the Semantic Web and linked data, and sustainability through collaboration. The article includes brief case studies, highlighting various projects involving the aerial photography collections at the University of Minnesota. The conclusion asserts the critical role played by geographic information librarians in effectively carrying out the strategies described in the article as they relate to the long-term sustainability of digital geospatial collections. 相似文献

This article probes ways in which the school-choice marketplace as it developed via chartering has not worked as well in practice as many had hoped. It includes reflection on the profoundly different operating principles and theories of action that separate the district and charter sectors in their pure forms. It also offers market-strengthening suggestions that blend the 2 approaches, organizing them under 10 categories. 相似文献

We compared SenseWear Armband versions (v) 2.2 and 5.2 for estimating energy expenditure in healthy adults. Thirty-four adults (26 women), 30.1 ± 8.7 years old, performed two trials that included light-, moderate- and vigorous-intensity activities: (1) structured routine: seven activities performed for 8-min each, with 4-min of rest between activities; (2) semi-structured routine: 12 activities performed for 5-min each, with no rest between activities. Energy expenditure was measured by indirect calorimetry and predicted using SenseWear v2.2 and v5.2. Compared to indirect calorimetry (297.8 ± 54.2 kcal), the total energy expenditure was overestimated (P < 0.05) by both SenseWear v2.2 (355.6 ± 64.3 kcal) and v5.2 (342.6 ± 63.8 kcal) during the structured routine. During the semi-structured routine, the total energy expenditure for SenseWear v5.2 (275.2 ± 63.0 kcal) was not different than indirect calorimetry (262.8 ± 52.9 kcal), and both were lower (P < 0.05) than v2.2 (312.2 ± 74.5 kcal). The average mean absolute per cent error was lower for the SenseWear v5.2 than for v2.2 (P < 0.001). SenseWear v5.2 improved energy expenditure estimation for some activities (sweeping, loading/unloading boxes, walking), but produced larger errors for others (cycling, rowing). Although both algorithms overestimated energy expenditure as well as time spent in moderate-intensity physical activity (P < 0.05), v5.2 offered better estimates than v2.2. 相似文献

As increasing numbers of students with disabilities access postsecondary education, research studies and literature reviews have investigated the needs of these students who chose to pursue postsecondary education. These articles included studies that (a) asked students with disabilities to identify needs and (b) summarized needs in literature reviews about students with disabilities in postsecondary education. This article summarizes needs and recommendations from college students with disabilities and authors who reviewed related literature from 1995–2006. The summary includes needs in five areas: self-determination, social skills, academic preparation, accommodations, and assistive technology (AT). Each of these areas of need is described and recommendations for practice are discussed. The purpose of this article is to identify a set of evidence-based transition practices that will address these needs and increase the likelihood of success for students who enroll in postsecondary education institutions. 相似文献
