Enhanced thermoelectric figure-of-merit in nanostructured p-type silicon germanium bulk alloys.

Abstract: A dimensionless thermoelectric figure-of-merit (ZT) of 0.95 in p-type nanostructured bulk silicon germanium (SiGe) alloys is achieved, which is about 90% higher than what is currently used in space flight missions, and 50% higher than the reported record in p-type SiGe alloys. These nanostructured bulk materials were made by using a direct current-induced hot press of mechanically alloyed nanopowders that were initially synthesized by ball milling of commercial grade Si and Ge chunks with boron powder. The enhancement of ZT is due to a large reduction of thermal conductivity caused by the increased phonon scattering at the grain boundaries of the nanostructures combined with an increased power factor at high temperatures.

Across the Great Divide: Knowledge Creation and Transfer Between Practitioners and Academics

Abstract: Observers have long noted a considerable gap between organizational research findings and management practices. Although volumes have been written about the probable causes and consequences of this gap, surprisingly little empirical evidence exists concerning the various viewpoints. The articles in this forum provide data on the role of academic-practitioner relationships in both generating and disseminating knowledge across boundaries. The contributions of each article are summarized in light of recent theories of knowledge creation, and suggestions are made for increasing the value and relevance of future research to both academics and practitioners.

Chapter 8: Relationships of Knowledge and Practice: Teacher Learning in Communities:

Abstract: Over the last 20 years, teacher learning has become one of the most important concerns of the educational establishment. It has been more or less assumed that teachers who know more teach better. This \"simple\" idea has governed multiple efforts to improve education in the arenas of policy, research, and practice by focusing on what teachers know or need to know. In this chapter, we do not question this basic idea. Rather, we point out that within various change efforts, there are radically different views of what \"knowing more\" and \"teaching better'' mean. In other words, there are radically different conceptions of teacher learning, including varying images of knowledge; of professional practice; of the necessary and/or potential relationships that exist between the two; of the intellectual, social, and organizational contexts that support teacher learning; and of the ways teacher learning is linked to educational change and the purposes of schooling. Different conceptions of teacher learning—although not always made explicit—lead to very different ideas about how to improve teacher educa­ tion and professional development, how to bring about school and curricular change, and how to assess and license teachers over the course of the professional life span.

Intellectual Capital Profiles: An Examination of Investments and Returns

Abstract: Using data collected from executives in 208 organizations, this study takes a configurational approach to examine how human, social, and organizational capital coexist to form distinct intellectual capital profiles across organizations. We then examine how investments in human resource management (HRM), information technology (IT), and research and development (R&D) differ across these intellectual capital profiles and investigate differences in financial returns and Tobin's q between the profiles. Results indicate that a relatively small group of superior performing organizations exhibit high levels of human, social, and organizational capital. Most firms, however, tend to focus primarily on only one form of intellectual capital, and a small group of underperforming organizations have very low levels of all three types of intellectual capital. At a general level, HRM and IT investments appear to influence intellectual capital development more than R&D investments. More specifically, HRM investments tend to be higher in firms with profiles high in human and social capital, while IT investments are stronger in firms with profiles high in social capital. Further, HRM, IT, and R&D investments are all very high in the group of superior performing organizations that have high levels of human, social, and organizational capital.
