National models for CPD: The challenges of C21st knowledge management
No full textTeacher quality is the most critical factor in improving educational outcomes (McKinsey, 2007). This paper proposes analytical frameworks for national models for continuing professional development (CPD). It examines the unacknowledged problem of the quality and extent of the evidence base underpinning teachers’ CPD. In the 21C through the use of ICTs the research and evidence base underpinning educational practice surely could be made accessible to all teachers and all providers of initial teacher training and CPD. The evidence base available internationally appears to be patchy. Yet this is taken for granted in the literature, and is rarely if ever acknowledged in the discourse about school and system improvement. This lack of research based professional knowledge, is a particular problem for subject specialist issues and is further compounded by the fact that research published in journals is not generally designed around questions teachers want answered. In short, the knowledge that is produced and the management of it within the education sector is lacking systemic organisation and dissemination. The paper outlines opportunities which exist for low cost interlinked national and international e-infrastructures to be developed to support knowledge sharing, but such collaboration may pose an insurmountable challenge for national and international agencies
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
World Heritage: Where are we? An empirical analysis
No full textA statistical analysis of the UNESCO World Heritage List is presented. The World Heritage Convention intends to protect global heritage of outstanding value to mankind, but there has been great concern about the missing representativity of the member countries. There is a strongly biased distribution of Sites according to a country’s population, area or per capita income. The paper reveals the facts but refrains from judging whether the existing distribution is appropriate or not. This task must be left to the discussion in the World Heritage Convention.Global public goods, world heritage, international organizations, international political economy, culture, UNESCO
Time-dependent 3D simulations of the hemodynamics in a stented coronary artery
No full textStenting is becoming the major interventional cardiology procedure worldwide. However restenosis remains a major limitation to the effectiveness of stents. Alterations to the local hemodynamics in the stented segment of the artery could be a potential factor in the development of in-stent restenosis. The characterization of wall shear stress and of blood flow patterns in a stented artery is therefore necessary for a good understanding of the role of hemodynamics in the development of in-stent restenosis. We have used a time-dependent 3D numerical model of a stented coronary artery to study the characteristics of the blood flow and the shear stress distribution. Our results show that the presence of the stent produces significant secondary flow that is limited to an annulus in the near wall region. Low shear stress zones were localized in the vicinity of the struts while the tips of the struts exhibited high values of shear stress. These results support the hypothesis that local hemodynamics may affect the development of in-stent restenosis and could influence the choice of stent geometries for future stent designs

No full textLetter from R. R. Zellick, Assistant Trust Officer at The Anglo California National Bank of San Francisco, to Joseph R. Goodman, regarding property owned by Dave Tatsuno. Zellick mentions a dispute between current tenants and Tatsuno, and that Tatsuno has asked Goodman to help locate trustworthy tenants.Personal correspondence, organizational records, government documents, publications, and other papers created or collected by Joseph R. Goodman documenting the forced removal and incarceration of Japanese Americans during World War II, as well as organized resistance to incarceration. Included in the collection are records of the Japanese Young Men's Christian Association and the Japanese American Citizens' League in San Francisco, including papers of the Japanese YMCA's executive secretary Lincoln Kanai; Sakai family papers; Goodman's correspondence to and from Japanese American incarcerees, organizations opposing forced removal and incarceration of Japanese Americans, the War Relocation Authority, and others; publications, photographs, and ephemera from the Topaz Relocation Center, where Goodman taught high school; War Relocation Authority records and publications; and newspaper clippings, pamphlets, and reports about forced removal and incarceration created by various government, religious, and civic organizations, in California and nationwide
Web 2.0 and knowledge management for local government in England – A model for the public sector?
No full textPURPOSE
Delivering success in the public and private sector requires staff to have access to the best knowledge possible about how to do their jobs well so a major challenge for employers is how to ensure their staff are making decisions based on the latest knowledge of best practice.
21st century professionals and policy makers are increasingly being required to demonstrate that their practice and decision making is evidence based.
This paper examines a new public sector knowledge management initiative across local government in England and Wales which aims to improve knowledge sharing across local government.
In response to a number of drivers for improvement, the Improvement and development Agency for local government in England (IDeA) has harnessed web 2.0 tools to support knowledge creation and sharing, and just in time learning to create a professional networking online environment - a ‘Facebook’ type environment for local government. The result is an pnline Communities of Practice for local government initiative .
DESIGN
This initiative was launched across local government in England and Wales in January 2008 and an arrangement with the local government improvement services in Scotland provides similar access to local government officers there. At the time of writing the initiative has over 30,000 members in over 700 online communities with new members joining every day.
The knowledge management strategy discussed in this paper was developed following a review of knowledge management literature and an analysis of the specific needs of the local government sector by the Improvement and Development Agency for local government in England. The data reported come from a number of sources including web statistics which are collected automatically and interviews carried out to identify ways in which the initiative is having impact.
RESEARCH LIMITATIONS/IMPLICATIONS
The impact of knowledge management initiatives can be hard to quantify but the paper outlines some proxy measures which give some indication of the value for money of this knowledge management strategy.
PRACTICAL IMPLICATIONS
The argument is made that online communities of practice can very quickly provide advantages and significant cost benefits to the public sector in spite of the limitations of the software and the fact that working practices will take many years to change.
It is argued that the approach set out in this article provides a model for other public sector organisations.
ORIGINALITY/VALUE
Knowledge transfer and research impact are areas in England of concern to both government and academics who in the REF 2013 will be judged on the impact of their research
This online communities of practice initiative is a new way of knowledge sharing and working across a whole public sector. It has the potential to revolutionise the ways professionals learn and carry on learning as well as the relationships between academics and potential users of research However, the establishing and managing of such an initiative requires national leadership on behalf of a sector
Beginning teachers’ roles and responsibilities
No full textThis chapter discusses teachers' roles and responsibilities as beginning teachers. It considers the key players in the school and their initial teacher education programme. The chapter examines how to navigate their school placement, taking an ecological approach to professional practice – looking at the policy level, community level, organisational level, interpersonal level and individual level. It then focuses on teacher's professional learning journey and the stages of development they go through. As teachers prepare for their first school placement, it is helpful to remember that they are joining a system of education that operates at many levels: individual, classroom, organisational, community and national policy levels. Conducting a contextual analysis of the school and local community is an important component of pre-placement preparation. Contextual analysis involves reviewing the external environment. Taking on the role of a beginning teacher means forging and managing professional relationships with adults, as well as pupils
