Interpersonal behaviour styles of primary education teachers during science lessons

This study reports the first development in Australia of primary science teacher typologies of teacher–student interpersonal behaviour, which was measured by students’ perceptions using the Questionnaire on Teacher Interaction (QTI). Earlier work with the QTI in The Netherlands has revealed eight different interpersonal styles, which were later confirmed with an American sample of secondary-school teachers and which were similar to types found with Australian secondary-school science teachers. The present study investigated the extent to which typologies found in earlier studies also apply to primary teachers. A cluster analysis was used to determine Australian typologies and to compare these with earlier findings. Prior typologies could only be partially confirmed, and the found typology of six styles was able to explain variance in both student outcomes and perceptions of cultural elements of the learning environment

Cancer immunotherapy--revisited

Item does not contain fulltextOur insight into antitumour immune responses has increased considerably during the past decades, yet the development of immunotherapy as a treatment modality for cancer has been hampered by several factors. These include difficulties in the selection of the optimal dose and schedule, the methods of evaluation, and financial support. Although durable clinical remissions have been observed with various immunotherapeutic strategies, the percentage of patients who benefited from these interventions has remained too small to justify the general use of such strategies. However, the recent positive results of clinical trials with novel immunoactive drugs as well as the unexpected finding of a positive interaction between immunotherapy and chemotherapy may herald a new era for the immunotherapy of cancer
