Critical role of leadership in nurturing a knowledge-supporting culture     

Vincent M?RibièreEmail author  Ale?a Sa?a?Sitar 《知识管理研究与实践》2003,1(1):39-48

This paper addresses the critical role leadership plays in the implementation and facilitation of knowledge management activities. Leadership is particularly important for organizations willing to ‘evolve’ their culture to a knowledge-supporting culture. Organizational culture has been identified as the main impediment to knowledge activities, and therefore leaders should model the proper behaviors causing culture to evolve in a way that enables and motivates knowledge workers to create, codify, transfer, and use and leverage knowledge. In the literature this leadership behavior is referred to as ‘leading through a knowledge lens’. Leading through a knowledge lens has some special characteristics since it is dealing with knowledge workers having specialized expertise. Leading them can be done only by intellectual power, conviction, persuasion, and interactive dialog. It requires skills that build confidence and engagement. Therefore, leaders should establish trust and commitment that will help the knowledge organization to achieve its knowledge and business goals.  相似文献

Binary Pathfinder: An improvement to the Pathfinder algorithm     

Vicente P. Guerrero-Bote  Felipe Zapico-Alonso  María Eugenia Espinosa-Calvo  Rocío Gmez Crisstomo  Flix de Moya-Anegn 《Information processing & management》2006,42(6):1484

The Pathfinder algorithm is widely used to prune social networks. The pruning maintains the geodesic distances between nodes. It has shown itself to be very useful in the analysis of, amongst others, citations in BIS (bibliometrics, informetrics, and scientometrics). It has even been proposed for the online display of the search results in an information retrieval system. However, its great time and space complexity limits its use in real-time applications and in networks of any considerable size.The present work describes an improved algorithm with considerably reduced time and space complexity. Its lower execution costs thus increase its applicability both in real time and to large networks.  相似文献   

Ethical issues in web data mining   总被引：2，自引：0，他引：2  

Lita van Wel  Lambèr Royakkers 《Ethics and Information Technology》2004,6(2):129-140

Web mining refers to the whole of data miningand related techniques that are used toautomatically discover and extract informationfrom web documents and services. When used in abusiness context and applied to some type ofpersonal data, it helps companies to builddetailed customer profiles, and gain marketingintelligence. Web mining does, however, pose athreat to some important ethical values likeprivacy and individuality. Web mining makes itdifficult for an individual to autonomouslycontrol the unveiling and dissemination of dataabout his/her private life. To study thesethreats, we distinguish between `content andstructure mining' and `usage mining.' Webcontent and structure mining is a cause forconcern when data published on the web in acertain context is mined and combined withother data for use in a totally differentcontext. Web usage mining raises privacyconcerns when web users are traced, and theiractions are analysed without their knowledge.Furthermore, both types of web mining are oftenused to create customer files with a strongtendency of judging and treating people on thebasis of group characteristics instead of ontheir own individual characteristics and merits(referred to as de-individualisation). Althoughthere are a variety of solutions toprivacy-problems, none of these solutionsoffers sufficient protection. Only a combinedsolution package consisting of solutions at anindividual as well as a collective level cancontribute to release some of the tensionbetween the advantages and the disadvantages ofweb mining. The values of privacy andindividuality should be respected and protectedto make sure that people are judged and treatedfairly. People should be aware of theseriousness of the dangers and continuouslydiscuss these ethical issues. This should be ajoint responsibility shared by web miners (bothadopters and developers), web users, andgovernments.  相似文献   

Enzyme engineering: accomplishments and prospects     

Daniel Thomas  Gèrard Gellf 《Endeavour》1981,5(3):96-98

Developments in enzyme technology could lead to a completely new type of chemical industry utilizing moderate conditions of pH, temperature, and pressure to produce, from wastes or by-products, high yields of complex chemicals without generating new waste products that pollute the environment. The new tools of this branch are immobilized, as opposed to dissolved, enzymes or whole cells with enzymatic capacity. Methods of biochemistry must be applied at the same time, including genetic manipulation, molecular ageing, and protein chemistry.  相似文献

Urban youths’ hybrid positioning in science practices at the margin: a look inside a school–museum–scientist partnership project and an after-school science program     

Jrène Rahm 《Cultural Studies of Science Education》2008,3(1):97-121

In what ways do urban youths’ hybridity constitute positioning and engagement in science-as-practice? In what ways are they “hybridizing” and hence surviving in a system that positions them as certain types of learners and within which they come to position themselves often as other than envisioned? To answer these questions, I draw from two ethnographic case studies, one a scientist–museum–school partnership initiative, and the other, an after-school science program for girls only, both serving poor, ethnically and linguistically diverse youth in Montreal, Canada. Through a study of the micro dialectics from the perspective of youth, I show what we can learn from examples of doing science in a formal and informal educational context supportive of marginalized science practices resembling in part, at least, science-as-practice. Through an integration of the findings with current discourses of relevance in science education such as funds of knowledge and youth centered, co-opted science, I contribute to the formulation of a global pedagogy of science education and in particular, what such may imply in the eyes of youth in French Canada.  相似文献
