Perceptual judgments for stair climbing as a function of pitch angle

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.     

Title IX and Retaliation: The Impact of Jackson v. Birmingham Board of Education on Higher Education

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.     

Quality Assessment, Student Need, and Pastoral Care at the University of Strathclyde

For young people moving from school to higher education, the continued provision of high quality pastoral care should be an important consideration. However, though all institutions provide some sort of service, its quality can vary significantly. Even where provision has been good, it has normally been seen as a 'bolt‐on' extra, rather than something central to the student's experience. At the University of Strathclyde, a key element in the creation of a more effective and integrated approach has been the development of the personal tutor role into that of the more clearly defined and structured one of Academic Counsellor.     

A prototype Semantic Web-based digital content exchange for schools in Singapore

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.
