Library directors are part of the infrastructure of information management, but how well do they manage their institutional knowledge for succession planning? Our study looked at strategies to ease managerial transitions between libraries, focusing on knowledge management, communities of practice, and mentorship. Our survey found that succession planning was dictated by local practice and size of library. The results of this paper inform knowledge of succession planning and reveal existing gaps between informal transfer of knowledge and structured knowledge management (KM), as well as librarians' resourcefulness. Library directors use KM strategies, mentoring, and involvement with communities of practice to foster innovation.  相似文献

The medical ultrasonic phased array technology was modified for the non-destructive testing of marble sculptures and the feasibility of the approach was evaluated. For this purpose, 1?MHz, 64-channel phased array electronic and phased array transducers were developed. The specifications of the electronics and the transducers are presented and discussed. Ultrasound images of inner structures of a marble sculpture are presented. The problem of the acoustic matching layers for different states of deterioration is discussed and the developments in view of a suitable matching layer solution are presented. This matching layer is combined with a new coupling technique that protects the marble surface. The results of experiments on ultrasound phantoms and on a marble sculpture are presented.  相似文献

Abstract

We thought that the close integration of theory and practice offered by constructivism promises unique opportunities to maximize learning in online courses using interactive software as the primary medium of communication. The purpose of this paper, therefore, is to examine the ‘goodness of fit’ between principles drawn from constructivist theories and the design and implementation of the interactive online course.  相似文献

abstract

The paper considers questions of ethics and methodology in international research. An action research project designed for Ghana/UNICEF as part of a consultancy on school attendance is used as a case‐study from which to examine the ethical dilemmas facing consultants and their clients in educational research carried out as part of international aid. Ethical dilemmas of resourcing, ownership, accountability and self‐interest are discussed by the English consultants. It thus has a double purpose. It both contributes to research on school attendance, and also furthers debate about methodology and constraints on it.  相似文献

Racial desegregation in higher education is taking on a new direction as the twenty‐first century approaches. The Brown v. Board of Education decision brought down legal racial barriers to segregated education, and this landmark US Supreme Court ruling was implicitly intended to apply to higher education as well. The positive changes for African Americans in removing racial barriers contributed significantly to the civil rights movement and opening avenues of opportunity. Yet, there has always been a fundamental tension between the removal of the vestiges of racial segregation to create equal educational opportunity, and the activist stance of addressing historical and current discriminatory educational policies. This is evident in the recent higher education desegregation and affirmative cases as the Federal Courts advocate the colour‐blind interpretation of higher education desegregation law and educational policy, while African Americans argue in favour of the enhancement of the public Historically Black Colleges and Universities and the explicit use of race as a form of diversity. This article examines the salient positions and racial identity politics surrounding this tension. I also argue that broader issues of racial control and power need to be addressed by educational institutions, the courts and the larger society in the debate about race, social justice and the removal of the vestiges of segregation.  相似文献
