    A publication trend in Physics Education by employing bibliometric analysis leads the researchers to describe current scientific movement. This paper tries to answer "What do Physics education scientists concentrate in their publications?" by analyzing the productivity and development of publications on the subject category of Physics Education in the period 1980--2013. The Web of Science databases in the research areas of "EDUCATION - EDUCATIONAL RESEARCH" was used to extract the publication trends. The study involves 1360 publications, including 840 articles, 503 proceedings paper, 22 reviews, 7 editorial material, 6 Book review, and one Biographical item. Number of publications with "Physical Education" in topic increased from 0.14 % (n = 2) in 1980 to 16.54 % (n = 225) in 2011. Total number of receiving citations is 8071, with approximately citations per papers of 5.93. The results show the publication and citations in Physic Education has increased dramatically while the Malaysian share is well ranked

    The Sound Manifesto

    Computing practice today depends on visual output to drive almost all user interaction. Other senses, such as audition, may be totally neglected, or used tangentially, or used in highly restricted specialized ways. We have excellent audio rendering through D-A conversion, but we lack rich general facilities for modeling and manipulating sound comparable in quality and flexibility to graphics. We need co-ordinated research in several disciplines to improve the use of sound as an interactive information channel. Incremental and separate improvements in synthesis, analysis, speech processing, audiology, acoustics, music, etc. will not alone produce the radical progress that we seek in sonic practice. We also need to create a new central topic of study in digital audio research. The new topic will assimilate the contributions of different disciplines on a common foundation. The key central concept that we lack is sound as a general-purpose information channel. We must investigate the structure of this information channel, which is driven by the co-operative development of auditory perception and physical sound production. Particular audible encodings, such as speech and music, illuminate sonic information by example, but they are no more sufficient for a characterization than typography is sufficient for a characterization of visual information.Comment: To appear in the conference on Critical Technologies for the Future of Computing, part of SPIE's International Symposium on Optical Science and Technology, 30 July to 4 August 2000, San Diego, C

    Cantos Mateos, Gisela; Zulueta, María Ángeles; Vargas-Quesada, Benjamín; Chinchilla-Rodríguez, Zaida. Estudio comparativo sobre la visualización de redes de co-words a través de los descriptores del Science Citation Index y de Medline. Atas de I Congresso ISKO Espanha e Portugal / XI Congresso ISKO Espanha, Oporto (Portugal), 7 a 9 de novembro 201, p. 173-189Objetivos: El presente estudio se centra en la investigación desarrollada en España sobre células madre comprendida entre los años 1997 y 2010. El objetivo fundamental consiste en la comparación de las líneas de investigación que ofrece el análisis de distintos tipos de descriptores, según su naturaleza documental, a partir de su aparición conjunta en los documentos. Material y Métodos: Las fuentes utilizadas han sido las bases de datos del Science Citation Index Expanded (SCI-E) y Medline, empleando para el estudio el mismo conjunto documental. El análisis aplicado ha consistido en la representación y visualización de las relaciones que se establecen entre los términos de indización. De un lado, se han empleado los descriptores utilizados por el SCI para indizar sus documentos: KeywordsPlus (KW+) y Keywords Author (KWA) y de otro, los descriptores MeSH utilizados por Medline. Las herramientas utilizadas para la visualización han sido el software Pajek, en combinación con el algoritmo PathfinderNetwork (PfNET) para la simplificación de las relaciones y el software VOSviewer.Resultados y Discusión: se han recuperado 3.078 documentos. A partir de ellos, en función del tipo de descriptor seleccionado, se han obtenido distintas imágenes sobre la investigación española en células madre entre 1997 y 2010. La visualización más clara y completa es la que ofrecen los descriptores KW+, permitiendo detectar hasta un total de seis líneas de investigación. La visualización de los KWA, por su parte, ofrece una imagen más diluida de las líneas de investigación, reflejando, sobre todo, la investigación de carácter más básico. Finalmente, la representación de las relaciones de los descriptores MeSH también se aproxima, sobre todo, a los estudios de carácter más básico. Conclusión: la comparación de las visualizaciones ha permitido determinar que los descriptores KW+ son la unidad de análisis más adecuada a la hora de realizar un análisis temático sobre un domino científico.Peer reviewe

    135-144Eugene Garfield’s contributions to global informetrics and scientometrics literature is significant. In this paper, a scientometric analysis of Eugene Garfield’s 50 highly cited papers is performed. His papers were published in 32 journals including top-ranked journals such as Nature and Science. The top 15 keywords with the strongest citation bursts from 1989 to 2009 and references with strong citation bursts are presented. Co-citation analysis and bibliographic coupling analysis based on source journals using VOSviewer were carried out. The result revealed that keywords 'citation relationship', 'scientific journals', 'biological journal’ and 'self-citations' started to burst/hotspot in 2002. The term 'citation analysis' has the highest number of four years' popularity as citation burst. The study further revealed that the top 50 publications of Eugene Garfield gained 8441 citations of the total citations of 9121 from 254 published documents. Garfield has Total Link Strength of 35 and has received 8511 citations which comes to 93.31% of the total citations and proved his dominance over the collaborators. Ninety percent of the papers (45) published in the USA and above 92% of the citations (8419) were also received from the USA's publications. Just five papers in three journals received 4856 citations (53.23%) of the total 9121 citations. These three journals include three papers in Science (with 3027); one each in Journal of the American Medical Association (with 1323 citations) and The Canadian Medical Association Journal (with 606 citations)
