Two experiments explored perception and action for stair climbing, with manipulations to the stair dimensions. In Experiment 1, a custom-built apparatus manipulated the stair dimensions, while three groups of participants made perceptual judgments of climbability. The groups differed significantly for absolute leg length (p < .0001), but there was no significant difference between the groups when stair dimensions were calculated relative to leg length. The selected tread depths and riser heights reflected constant proportions of participants' leg length. Using the pitch angles formed as a composite metric, the results revealed that all groups selected 60 degrees as the limit for climbability. Experiment 2 scaled pitch angle systematically from 20 degrees to 80 degrees, and participants judged 65 degrees and beyond to be unclimbable. These results provided evidence that pitch angle might be used in perceptual judgments for stair climbability. 相似文献

Title IX and Retaliation: The Impact of Jackson v. Birmingham Board of Education on Higher Education
Kerry Brian Melear 《Journal of Personnel Evaluation in Education》2007,19(3-4):91-103
In 2005, the United States Supreme Court rendered a closely divided opinion that extends the protections against discrimination
provided by Title IX of the Education Amendments of 1972 to include a private cause of action for retaliation in Jackson v. Birmingham Board of Education. Therefore, “whistleblowers,” or employees who report allegedly discriminatory practices, can file suit against employers
who retaliate against them on the basis of their complaints under the auspices of Title IX, which prohibits discrimination
“on the basis of sex” by recipients of federal education funds. Unlike other federal anti-discrimination laws such as Title
VII of the Civil Rights Act of 1964, retaliation is not expressly mentioned within the text of Title IX, and the Supreme Court
reasoned that the broad language of the statute encompasses implied protections against retaliation, regardless of the gender
of the employee who alleges retaliatory action. As a result of Jackson, the first generation of litigation against colleges and universities under this expanded standard has begun to navigate
the federal courts. This article analyzes the Supreme Court’s opinion in Jackson and the related cases representing the first application of the retaliation standard articulated therein to colleges and
universities. The article concludes with suggestions for insulation from liability associated with alleged retaliation claims
against administrators and educational institutions. 相似文献

Singapore has many large and educationally valuable digital collections and is planning the development of many more. These digital collections contain historical, cultural and scientific multimedia objects, along with learning objects. At present, school teachers and pupils find it hard to locate many of these resources using traditional search engines. This paper describes a research investigation into the design and subsequent development of a prototype digital resource discovery portal (Digital Content Exchange) based on Semantic Web technologies, and explores some of the educational issues raised. The research project explored how the features of the Semantic Web might offer valuable additional educational benefits and affordances beyond that of those based on existing information retrieval technologies. 相似文献

Within society, there are many publications regarding expectations of firm performance. These include analysis, industry insiders and ranking service. Within sports, bookmakers provide betting odds that reflect the expected outcome of matches and are determined by several factors. The purpose of this study is to analyse the determinants of expected match outcome (i.e. betting odds) and compare them to those of actual match outcome. Data from the 2010/2011 season of the German Bundesliga (soccer) are made available that are combined with betting odds for each match. Regression results show that several factors, such as difference in standing between team and opponent, difference in competitions played, difference in points earned over the last five matches, differences in standing last season and home advantage significantly influence expected match outcome. On the contrary, actual match outcome is only determined by the latter two factors. 相似文献

This article describes part of a study that explored the responses of nine‐ and ten‐year‐old children during a picturebook read aloud in a small group setting in a New Zealand classroom. The read aloud was interactive, where the participants were encouraged to respond to the book and to each other throughout the session. The authors created a framework for analysing the responses, adapting the model of Lawrence Sipe (2008) with its five categories of literary understanding, by expanding on the analytical category to enable a finer analysis of the responses. This article discusses the children's depth of thinking and the understandings they developed as they engaged with the read aloud. It also describes how the adapted framework allowed a closer analysis of these understandings, including the way the elements of art used in the illustrations contributed to the children's ideas. The findings suggest ways picturebooks can be used to promote children's thinking and how teachers can guide discussion about a complex text. Implications for use of the framework in further research are discussed. 相似文献
