A brief review is given concerning the status of the theoretical work on nucleon spectral functions. A recent concern about the validity of the concept of spectroscopic factors as deduced from (e,ep) reactions at higher Q, is discussed in some detail. The consequences of the observed spectral strength are then considered in the context of nuclear saturation. It is argued that short-range correl...

Migration of labor in response to structural changes in the U.S. economy is explored. An empirical study of the migration decision and wage determination is used to evaluate: 1) whether unemployment plays a larger role in motivating the decision to migrate than spatial wage differences and 2) whether the population can be characterized as homogeneous regarding migration and wage determination. ...

This article describes a functional model of self-determination as a dispositional characteristic of individuals. This model has been used to conduct research to examine the impact of self-determination on the lives of people with developmental and other disabilities, to describe the development of self-determination, and to design interventions to promote self-determination for people with and...

Physical education teachers can influence students’ self-determination through the motivational strategies they use. In this study, the authors examined the relationship between teachers’ perceptions of class average self-determination, the teachers’ self-determination, and their reported use of 3 motivational strategies: autonomy support, structure, and involvement. They examined the relations...

BACKGROUND Older persons' right to exercise self-determination in daily life is supported by several laws. Research shows that older persons' self-determination is not fully respected within the healthcare sector. In order to enable and enhance older persons' self-determination, extensive knowledge of older persons' self-determination is needed. The aim of this study was to explore experiences ...
