The Citation Cloud of a biomedical article: a free,public, web-based tool enabling citation analysis

Background:An article''s citations are useful for finding related articles that may not be readily found by keyword searches or textual similarity. Citation analysis is also important for analyzing scientific innovation and the structure of the biomedical literature. We wanted to facilitate citation analysis for the broad community by providing a user-friendly interface for accessing and analyzing citation data for biomedical articles.Case Presentation:We seeded the Citation Cloud dataset with over 465 million open access citations culled from six different sources: PubMed Central, Microsoft Academic Graph, ArnetMiner, Semantic Scholar, Open Citations, and the NIH iCite dataset. We implemented a free, public extension to PubMed that allows any user to visualize and analyze the entire citation cloud around any paper of interest A: the set of articles cited by A, those which cite A, those which are co-cited with A, and those which are bibliographically coupled to A.Conclusions:Citation Cloud greatly enables the study of citations by the scientific community, including relatively advanced analyses (co-citations and bibliographic coupling) that cannot be undertaken using other available tools. The tool can be accessed by running any PubMed query on the Anne O''Tate value-added search interface and clicking on the Citations button next to any retrieved article.

What Should Instructional Designers & Technologists Know About Human Performance Technology?

Human performance technology (HPT) is having a significant impact on the field of instructional design and technology (IDT), and many IDT graduate programs now offer training in HPT to their students. However, some IDT programs may be struggling with the extent to which they should incorporate the principles and techniques of HPT into their courses. To provide some determination of which specific skills and competencies in HPT graduates of IDT programs should have, an online survey was administered to 24 IDT faculty members and 45 members of local chapters of the International Society for Performance Improvement and the American Society for Training and Development. Respondents rated the importance of HPT competencies for graduates of IDT programs. Results suggest strong support for the inclusion of HPT concepts in the curricula of IDT graduate programs. Implications of these results for IDT graduate programs, as well as for distinguishing HPT as a field of specialization separate from IDT, are discussed.     

王者的背影——记三巨头Moon、Sky、Grubby征战WCG2009旅程

如果这个魔坛只有一个绝世高手,那他注定是寂寞的,因为无敌而寂寞。就如独孤求败一样没有对手的追求只能沉浸在无以为战的寒冷高处,最终在遗憾中慢慢老去!如果这个魔坛只有两个绝世高手,无疑他们的命运将会是残酷的,因为这两个人天生就要成为对手,没有选择、无法逃避。书中写到：高手的一生就只为追求对手,他们眼中只有天下第一之争的宿命对决。魔兽中亦如此。     

New technology-based firms in Germany: a survey of the recent evidence

The importance and contribution of new technology-based firms (NTBFs) to long-term economic development is at the centre of a controversial debate. This paper provides an overview of the current status of research on various issues concerning NTBFs in Germany. The issues covered include the incidence of start-up firms in Germany's technology-intensive sectors and their regional clustering. The review also shows that NTBFs play an important role with regard to the transfer, adoption and diffusion of technology. The public support and policy initiatives for NTBFs in Germany are also discussed.     

Potential knowledge management contributions to human performance technology research and practice

This article considers three aspects of the knowledge management (KM) literature that have the potential to enhance human performance technology (HPT) research and practice. First, we believe the recent attempt by economists to describe and quantify intellectual capital can help HPT to better evaluate and defend organizational expenditures/investments for performance improvement initiatives. Second, the emerging KM literature explores the linkages between information, learning and performance, provides a common point of intersection for our fields, and can enhance our analysis and implementation of information (as opposed to training) solutions as well as inform and expand our conceptual and theoretical understanding. Third, we have observed that both KM and HPT practitioners are increasingly concerned with the learning that takes place outside the confines of traditional formal training environments. We briefly review the electronic performance support systems literature from HPT and KM, noting the similarities in epistemology, design, and interventions. Finally, we highlight the KM research agenda and suggest related opportunities for HPT research.     

Addressing violence against teachers: A social-ecological analysis of teachers' perspectives

Much research has been dedicated to supporting school communities in combating the problem of school violence. However, violence directed toward teachers is under-investigated, and knowledge of how to support teachers is limited. This qualitative study used conventional content analysis to assess teachers' recommendations for preventing and improving the response to teacher-directed violence. The sample included 245 prekindergarten through 12th grade teachers, all of whom experienced school violence and participated in a larger national survey study on violence against teachers. Using a social-ecological framework and conventional content analysis, teacher recommendations for addressing teacher victimization were identified and organized at the individual, school, community, and society levels. Themes around conflict resolution strategies; improving policies, resources, and relationships with administrators; increasing parental involvement; and changing culture and laws were highlighted. Implications for research, practice, and policy are discussed.     

The comparability of the Test of Cognitive Skills with the Wechsler Intelligence Scale for Children-Revised and the Stanford-Binet: Fourth edition with gifted children

The comparability of the Test of Cognitive Skills (TCS) with the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) with 75 elementary- and middle-school-aged gifted students was investigated. Results indicated that the mean Cognitive Skills Index was about 6 points higher than the WISC-R FSIQ and about 9 points higher than the SBIV Composite score. Correlation coefficients between the TCS Cognitive Skills Index and the SBIV Composite score and the WISC-R FSIQ were.51 and.41, respectively. Absolute differences between individual scores revealed that 44% of the students' SBIV Composite scores were more than 10 points different than their Cognitive Skills Index, and 28% of the students' WISC-R FSIQ scores were more than 10 points different. The results indicated limited comparability between the TCS and WISC-R and SBIV. The implications of these findings and future research questions are discussed.
