Cross-hierarchical interconnectivity is a social process of transmission and alignment of previously separated pieces of knowledge from idiosyncratic contexts of individuals at different hierarchical levels in an organisation. This paper advocates that the management of interconnectivity can contribute to organisational competitiveness, especially in terms of adaptability, innovation, and cohesion. Based on the parameters of mode, actor's culture, time, direction, type of knowledge, and medium, a portfolio of interconnectivity is suggested and the core forms and mechanisms of interconnectivity, which are represented in the portfolio matrix, are discussed in depth. Finally, the specific culture of corporate executives and how it can be improved in order to encourage interconnectivity is analysed. 相似文献

Zusammenfassung. Die Integration mobiler Rechner in bestehende Netze erfordert eine umfassende Unterstützung. Die Hauptgründe dafür sind die
Vielfalt der eingesetzten Technologien sowie fehlende Konzepte in den bestehenden Systemen. In diesem Artikel werden M?glichkeiten
zur system- und anwendungsseitigen Unterstützung mobiler verteilter Systeme diskutiert. Nach einer kurzen Einführung in die
Problemstellungen des Forschungsgebietes werden Ans?tze für eine systemseitige Unterstützung mobiler Anwendungen und Dienste
anhand einer Softwareplattform beschrieben. Danach wird ein Modell zur Aufteilung mobiler Anwendungen vorgestellt, das verschiedene
system- und anwendungsseitige Unterstützungsmechanismen integriert. Abschlie?end wird das Modell zu einem Ansatz auf Basis
von Software-Komponenten verallgemeinert. Die Darstellung erfolgt anhand von Beispielsystemen, an deren Entwicklung die Autoren
ma?geblich beteiligt waren und sind.

In addition to providing information on the inheritance of dyslexia, the present study of eleven three-generation families
has provided a unique opportunity to compare affected and unaffected family members at all ages. The data presented here are
based on pedigree information, a questionnaire administered to all participating family members in relation to sex ratio,
handedness, the severity of dyslexia by sex, pre- and perinatal complications, medical complications, years of education and
earning ability, and a battery of standardized tests to define the presence or absence of dyslexia. The pattern of inheritance
was consistent with the postulated autosomal dominant mode of inheritance and penetrance was found to be > 90 percent. Of
73 individuals determined to have a gene leading to dyslexia, seven were classified as obligate carriers and six as compensated
adults who had no current symptoms or diagnostic evidence of dyslexia. The sex ratio (1.06) was not different from the expected
ratio of 1.04. Left-handedness, major pre- and perinatal complications, and autoimmune disorders and allergy were not more
common in dyslexics than non-dyslexics. The number of years of education and average income were similar in affected and unaffected
family members. Compensated adults and obligate carriers were similar to unaffected family members in each of these parameters. 相似文献

An aperçu of the reform process in higher education in the Russian Federation is given. It begins with a statement of the objectives of reform and a listing of the laws and decrees concerning it promulgated in 1991, 1992, and 1993. Great weight has been placed on the setting of standards and the creation of mechanisms to enforce these standards. Also, efforts are being made to adapt certain higher education course programmes to regional needs. The article concludes with a short discussion of current problems. 相似文献

One thousand thirty-three ninth-grade students from Western and Middle-Eastern ethnic background in 30 classrooms responded to a questionnaire assessing ethnic attitudes. The questionnaire was administered at the beginning and again at the end of these students' first year in ethnically desegregated classrooms. No marked changes in ethnic attitudes were noted as a function of the students' individual academic or social status in the classroom, but there were noteworthy changes associated with the relative status in the classroom occupied by the students' ethnic groups. Positive attitude change among Western (majority) students occurred when both ethnic groups in the classroom were of equal status, and when the MiddleEastern (minority) group was of superior academic status to the Western group. Positive change among the Middle-Eastern group occurred when it occupied superior status in the classroom. 相似文献
