Network-based control of nonlinear large-scale systems composed of identical subsystems     

Branislav Rehák  Volodymyr Lynnyk 《Journal of The Franklin Institute》2019,356(2):1088-1112

This paper deals with a control of coupled nonlinear identical systems that admit full exact feedback input-output linearization. The subsystems are linearized using this nonlinear transformation. In the next step, an auxiliary low-dimensional system is derived whose stability implies stability of the original large-scale system. The control law is designed so that the control loops are only local, no information exchange between subsystems is required. Unknown time delay in the feedback are allowed. Two cases are studied: equal time delay for all subsystems or different delay in all subsystems. Results are illustrated by two examples.  相似文献

Lernkultur: überlegungen zu einer kulturwissenschaftlichen Grundlegung qualitativer Unterrichtsforschung     

Fritz-Ulrich Kolbe  Sabine Reh  Bettina Fritzsche  Till-Sebastian Idel und Kerstin Rabenstein 《Zeitschrift für Erziehungswissenschaft》2008,11(1):125-143

Zusammenfassung In der Kritik an der schulp?dagogischen Rezeption des Kulturbegriffs, insbesondere an der normativ aufgeladenen Konzeption einer „neuen Lernkultur“, wird in diesem Aufsatz an einem sozialwissenschaftlichen, im engeren Sinne „praxistheoretischen“ Verst?ndnis von Kultur Anschluss genommen. Lernkultur konstituiert sich in p?dagogischen Praktiken, in regelgeleiteten, typisierten und routinisierten, k?rperlich aufgeführten und Interaktionen einschlie?enden Bearbeitungen verschiedener (p?dagogischer) Differenzen, etwa der zwischen der sozialen Ordnung eines p?dagogischen Angebotes und anderen Ordnungen, zwischen Vermittlung und Aneignung und der zwischen schulisch relevantem und anderem Wissen. Diesem Verst?ndnis von Lernkultur entspricht methodologisch die Entscheidung für eine in besonderer Weise vorgehende, videobasierte Erforschung p?dagogischer Praktiken. Das w?re als Konstituierung einer „empirischen Didaktik“ zu verstehen.   相似文献   

Anatomy as a Model Environment for Acquiring Professional Competencies in Medicine: Experiences at Harvard Medical School     

Katherine G. McDaniel  Taylor Brown  Caitlin C. Radford  Cynthia H. McDermott  Trudy van Houten  Martha E. Katz  Dana A. Stearns  Sabine Hildebrandt 《Anatomical sciences education》2021,14(2):241-251

Anatomy education provides students with opportunities to learn structure and function of the human body, to acquire professional competencies such as teamwork, interpersonal skills, self-awareness, and to reflect on and practice medical ethics. The fulfillment of this wide potential can present challenges in courses that are part of an integrated curriculum and shorter than traditional courses. This new reality, together with students' increasing concern about the stresses within medical education, led to efforts at Harvard Medical School to implement practical steps toward an optimal learning environment in anatomy. These were based on core elements of ethical anatomy education and principles of trauma-informed care. Anatomy is conceptualized here as the “first clinical discipline,” with relational interactions between anatomical educators, medical students, and body donors/patients. Essential prerequisites for the implementation of this work were support by the medical school leadership, open partnership between engaged students and faculty, faculty coordination, and peer-teaching. Specific interventions included pre-course faculty development on course philosophy and invitations to students to share their thoughts on anatomy. Student responses were integrated in course introductions, combined with a pre-dissection laboratory visit, an introductory guide, and a module on the history and ethics of anatomy. During the course, team-building activities were scheduled, and self-reflection encouraged, for example, through written exercises, and elective life-body drawing. Students' responses to the interventions were overall positive, but need further evaluation. This first attempt of a systematic implementation of an optimal learning environment in anatomy led to the identification of areas in need of adjustment.  相似文献   

Ethical dilemmas in individual and collective rights‐based approaches to tertiary education scholarships: the cases of Canada and Cuba     

Sabine Lehr 《比较教育学》2008,44(4):425-444

One of the ongoing debates in Canadian higher education is the dilemma of the brain drain and the seemingly conflicting goals between the strategies and intentions of various government departments. While Citizenship and Immigration Canada aims to recruit the brightest students from across the globe to study in Canada and to enable their long‐term stay as permanent residents and ultimately as citizens, the Canadian International Development Agency is mandated to strengthen human capacity in developing countries. This paper provides a critical analysis of the brain drain problem by juxtaposing Canadian policies with Cuban policies as manifested in the two countries’ divergent approaches to international students and tertiary education scholarships for students from poorer countries. Following an overview of the existing scholarship programmes in both countries, ethical and philosophical considerations are examined that appear to underlie the two countries’ individual‐rights‐based and collective‐rights‐based justifications for making decisions about the terms on which students from other countries are permitted to study in Canada and Cuba.  相似文献

INTRODUCTION A large number of environmental digital librar- ies have been designed and implemented recently to effectively manage environmental data such as satel- lite photos and images, map images, cartographic materials, and so on. Support for storing, distributing, searching for, retrieving, and utilizing this informa- tion is imperative in order for it to be used to its maximum potential benefit and effectiveness (Hicks and Tochtermann, 1998). The variability of envi- ronmental data…  相似文献

Critical intercultural conversations: using activity systems analysis as a tool for educational ethnography     

Sabine Siekmann  Joan Parker Webster 《Ethnography and Education》2019,14(3):377-393

ABSTRACT

This paper explores the tensions that exist between the recognition of the importance of ethnicity and culture for individual and group identities without essentilisation, by reframing conceptualisations of multi- and interculturalism. Drawing from our ongoing ethnography conducted with a research community of Alaska Native PhD candidates involved in participatory action research, we examine how situated and multiple positionalities enacted through participation in Engeström’s concept of an ‘activity system’ can: (a) contribute to the ‘doing’ of ethnography and provide an analytic framework for ethnographic research; and, (b) contribute to understandings of multi- and intercultural education that promote the questioning of hierarchical power structures through dialogue aimed toward equity and social justice.  相似文献
