Bibliometric studies on single journals: a review

This paper covers a total of 82 bibliometric studies on single journals (62 studies cover unique titles) published between 1998 and 2008 grouped into the following fields; Arts, Humanities and Social Sciences (12 items); Medical and Health Sciences (19 items); Sciences and Technology (30 items) and Library and Information Sciences (21 items). Under each field the studies are described in accordance to their geographical location in the following order, United Kingdom, United States and Americana, Europe, Asia (India, Africa and Malaysia). For each study, elements described are (a) the journal’s publication characteristics and indexation information; (b) the objectives; (c) the sampling and bibliometric measures used; and (d) the results observed. A list of journal titles studied is appended. The results show that (a)bibliometric studies cover journals in various fields; (b) there are several revisits of some journals which are considered important; (c) Asian and African contributions is high (41.4 of total studies; 43.5 covering unique titles), United States (30.4 of total; 31.0 on unique titles), Europe (18.2 of total and 14.5 on unique titles) and the United Kingdom (10 of total and 11 on unique titles); (d) a high number of bibliometrists are Indians and as such coverage of Indian journals is high (28 of total studies; 30.6 of unique titles); and (e) the quality of the journals and their importance either nationally or internationally are inferred from their indexation status

The geography of references in elite articles: What countries contribute to the archives of knowledge

This study is intended to find an answer for the question on which national "shoulders" the worldwide top-level research stands. Traditionally, national scientific standings are evaluated in terms of the number of citations to their papers. We raise a different question: instead of analyzing the citations to the countries' articles (the forward view), we examine referenced publications from specific countries cited in the most elite publications (the backward-citing-view). "Elite publications" are operationalized as the top-1% most-highly cited articles. Using the articles published during the years 2004 to 2013, we examine the research referenced in these works. Our results confirm the well-known fact that China has emerged to become a major player in science. However, China still belongs to the low contributors when countries are ranked as contributors to the cited references in top-1% articles. Using this perspective, the results do not point to a decreasing trend for the USA; in fact, the USA exceeds expectations (compared to its publication share) in terms of contributions to cited references in the top-1% articles. Switzerland, Sweden, and the Netherlands also are shown at the top of the list. However, the results for Germany are lower than statistically expected

Thermophysical Phenomena in Metal Additive Manufacturing by Selective Laser Melting: Fundamentals, Modeling, Simulation and Experimentation

Among the many additive manufacturing (AM) processes for metallic materials, selective laser melting (SLM) is arguably the most versatile in terms of its potential to realize complex geometries along with tailored microstructure. However, the complexity of the SLM process, and the need for predictive relation of powder and process parameters to the part properties, demands further development of computational and experimental methods. This review addresses the fundamental physical phenomena of SLM, with a special emphasis on the associated thermal behavior. Simulation and experimental methods are discussed according to three primary categories. First, macroscopic approaches aim to answer questions at the component level and consider for example the determination of residual stresses or dimensional distortion effects prevalent in SLM. Second, mesoscopic approaches focus on the detection of defects such as excessive surface roughness, residual porosity or inclusions that occur at the mesoscopic length scale of individual powder particles. Third, microscopic approaches investigate the metallurgical microstructure evolution resulting from the high temperature gradients and extreme heating and cooling rates induced by the SLM process. Consideration of physical phenomena on all of these three length scales is mandatory to establish the understanding needed to realize high part quality in many applications, and to fully exploit the potential of SLM and related metal AM processes

Global dimension in engineering education : promoting global learning in Spanish universities

La iniciativa ‘Dimensión Global en los Estudios Tecnológicos’ (GDEE) es una red que pretende mejorar el conocimiento, la comprensión crítica y los valores actitudinales de los estudiantes y de los postgraduados de las universidades científicotecnológicas en relación al Desarrollo Humano Sostenible (DHS). El objetivo es promover la integración del DHS como tema transversal en el currículo, mediante la mejora de las competencias de los profesores y a través de su participación y la de los estudiantes en iniciativas relacionadas con el DHS. La iniciativa empezó como un proyecto de colaboración entre un consorcio de universidades europeas y ONGs financiado por EuropeAid. Esta contribución presenta y discute la experiencia europea GDEE, profundizando las barreras y oportunidades encontradas, centrándose especialmente en la replicabilidad potencial de esta iniciativa. Estos resultados se complementan con la caracterización y el análisis comparativo del perfil académico de una comunidad de profesores implicados en actividades promovidas por GDEE.Peer ReviewedPostprint (author's final draft
