Measuring student teachers' basic psychological needs

In the Self-Determination Theory (SDT) basic psychological needs for relatedness, autonomy and competence are distinguished. Basic psychological need fulfilment is considered to be critical for human development and intrinsic motivation. In the Netherlands, the concept of basic psychological need fulfilment is introduced in the curricula of many teacher education institutes. In five teacher education institutes for primary school teachers, study coaches use a Dutch version of the Basic Psychological Needs Scale (BPNS), to collect data to be used in a discussion with student teachers about their intrinsic motivation for a specific part of the teacher education course. On the basis of the outcomes of this discussion, study coaches and student teachers derive consequences for day to day practice in their classrooms. The data were also used to establish whether the theoretical distinction between three basic psychological needs is found in this sample of student teachers in the Netherlands. The results show that the constructs of relatedness, autonomy and competence are found and can be measured by using a 14-item five-point scale, partly based on the original BPNS, and partly on new items that focus on different sources of perceived need fulfilment, namely teacher education in general, the study coach and fellow students

THE CHEMISTRY OF THE REACTION OF URANIUM HEXAFLUORIDE WITH ACTIVATED CARBON

The effects of temperature, time and other variables on the rate and extent of reaction between UF/sub 6/ and various types, grades and particle sizes of commercial activated carbon have been studied experimentally. It is shown that both hydrolysis and reduction of the UF/sub 6/ occur, the latter more slowly than the former. Reduction leads to the formation of a mixture of fluorocarbons ranging from CF/sub 4/ to a wax-like maternial volatile only above 250 deg C. There is also evidence for the adsorption of UF/sub 6/ on an undetermined substrate. (auth

Currently cohabiting: relationship attitudes, expectations and outcomes

This study uses prospective data from the British Household Panel Survey to analyse individuals’ relationship expectations and subsequent outcomes between 1998 and 2005. How do relationship expectations differ by age, sex, previous relationship history and parenthood? How do attitudes towards cohabitation differ by age, sex, previous relationship history and parenthood? Prospective data are particularly well suited to answering these questions as the relationship expectations are collected whilst the subjective state exists, allowing systematic empirical investigation of social change
