Sustainable development and hospitality education : employers’ perspectives on the relevance for graduate employability

This paper examines hospitality employers’ perspectives of sustainable development and the implications for hospitality education, particularly graduate employability. An exploratory approach is used in this research where semi-structured interviews were conducted with employers of hospitality graduates. The results established that respondents had mixed understandings of the meaning and relevance of sustainable development. These employers are, however, gradually recognising the value of sustainability for their business. Though it is not currently a priority in terms of a critical employability skill specifically for the hotel sector, related industries seem more mindful of the implications of sustainability credentials. Thus, hospitality educators need to take appropriate actions in subject specific areas where sustainable development is critical to employment opportunities, creating more industry ready graduates who are also globally aware citizens

Biomedical research with cyclotron produced radionuclides

Progress is reported on: metabolic and tumor localization in man and animals; radiodrug development; dosimetry for internally deposited isotopes; and radioactive material transfer system. Based on experience with /sup 13/N-glutamate in osteogenic sarcoma and Ewing's sarcoma, we conclude that (a) the /sup 13/N label enters tumor tissue rapidly at a rate similar to that at which activity leaves the blood, suggesting that the labeled glutamate itself is being transported into the tumor rather than some labeled metabolite; (b) uptake in the tumor is related to its metabolic activity, but factors such as blood flow are also important; (c) changes in the glutamate scan accurately reflect the response of osteogenic sarcoma to pre-operative chemotherapy as measured by conventional means, and that it is desirable to extend this experience to other types of tumors. /sup 13/N-Glutamate (and other /sup 13/N-labeled compounds) afford several advantages over conventional tumor imaging agents, such as rapid blood clearance and localization, low radiation exposure and the possibility of obtaining accurate, three-dimensional quantitative images via positron emission tomography. It is doubtful that these advantages will justify the routine use of /sup 13/N-glutamate to detect tumors or to monitor therapy except in clinical situations where conventional techniques are unsatisfactory. The value of /sup 1/3N-glutamate is as a tool to assess the metabolic requirement of neoplastic tissue in cancer patients in-vivo. (PCS
