Stewart was supported by SERC Grant GR/H 81108. We confirm a conjecture, due to Grötschel, regarding the intersection vertices of two longest cycles in a graph. In particular, we show that if G is a graph of circumference at least k + 1, where k 2 f6; 7g, and G has two longest cycles meeting in a set W of k vertices, then W is an articulation set. Grötschel had previously proved this result for...

As part of the Basic Science Survey Series for Dentistry, members of the American Dental Education Association (ADEA) Physiology, Pharmacology, and Therapeutics Section surveyed directors of physiology courses in North American dental schools. The survey was designed to assess, among other things, faculty affiliation and experience of course directors, teaching methods, general course content a...

BACKGROUND Healthcare decision-making is largely reliant on evidence-based medicine; building skills in scientific reasoning and thinking among medical students becomes an important part of medical education. Medical students in India have no formal path to becoming physicians, scientists or academicians. OBJECTIVES This study examines students' perceptions regarding research skills improveme...

We study the quantum group gauge theory developed elsewhere in the limit when the base space (spacetime) is a classical space rather than a general quantum space. We show that this limit of the theory for gauge quantum group Uq(g) is isomorphic to usual gauge theory with Lie algebra g. Thus a new kind of gauge theory is not obtained in this way, although we do find some differences in the coupl...

BACKGROUND Health education interventions are generally complex. Their outcomes result from both the intervention itself and the context for which they are developed. Thus, when an intervention carried out in one context is reproduced in another, its transferability can be questionable. We performed a literature review to analyze the concept of transferability in the health education field. M...

Most field ecology is conceived and financed by scientists from urban areas but is actually carried out in rural areas. Field staff can either be imported from urban areas or recruited from local residents. We evaluated the advantages and disadvantages of involving rural residents as local technicians over a 25- year period at active field research site in Costa Rica. We defined "local technici...

The purpose of this paper is to critically evaluate the use of action research as a tool for developing critical reection which has the potential to lead to change and development in practice in education, in particular, in the area of special educational needs (SEN) and inclusion. In order to support and illustrate the critique, a case study of a group of Dutch practising teachers and educati...

Many epidemiological and clinical studies in Europe, especially in Eastern Europe and countries in transition, are of poor methodological quality because of lack of background knowledge in clinical epidemiology methods and study designs. The only way to improve the quality of epidemiological studies is to provide adequate undergraduate and/or postgraduate education for the health professionals ...

AIM Poor nutritional status is common in older adult patients. The present study aimed to explore barriers and facilitators to nutritional care of elderly patients in acute care settings. METHODS Data were collected through individual face-to-face interviews with 12 registered nurses, and analyzed using interpretive description methodology. RESULTS Two core themes emerged from the analysis ...
