Journal of Special Education and Rehabilitation , 2013, DOI: 10.2478/v10215-011-0030-6
Abstract: The purpose of the research was to see whether work of special educators and rehabilitators in the regular school has a positive influence on peer relationship among students with delayed cognitive development.The accent was on friendship quality, social competence and antisocial behavior. The research comprised 150 students with slow cognitive development, 52 of who have support of special educators and rehabilitators in regular education, while the remaining 98 students are without support. Friendship quality was evaluated applying Friendship Quality Questionnaire. School Social Behavior Scale was used in order to evaluate social competence and antisocial behavior. Differences among the groups were examined by t-test from SPSS 14 Windows software package.The results have shown that students with slow cognitive development having support from special educators and rehabilitators evaluate their friendship more qualitative. Students with delayed cognitive development attending schools without special educators and rehabilitators engaged demonstrate better level of the social competence. As far as antisocial behavior concerns, no differences were found. The results obtained indicate need for redefining the role of special educators and rehabilitators in regular primary education.

Vanti, Nadia;
Ciência da Informa??o , 2005, DOI: 10.1590/S0100-19652005000100009
Abstract: this article deals with quantitative studies applied to the internet and the web. it addresses the concept of webometrics, its scope, uses and possible designations. it points out the differences between this concept and cybermetrics and it establishes the relationship that these two methods maintain with the tradicional fields of bibliometrics, scientometrics and informetrics. it also focuses on a resource that has been calling much attention among researchers, not only because it facilitates surfing on the web sites, but also because it represents one of the most relevant indicators in webometric studies: weblinks. toward the end, this article reviews the research that has been done about structure, functions and motivations for creating links on the web space.

Biblionline , 2010,
Abstract: This paper analyzes the size, visibility,brightness, the average density of links andweb impact factor of the federal publicuniversities in the North and Midwest in orderto investigate the presence of these institutionsin the network. It shows that, withtechnological advances, webometrics hasbecome a product for innovation, bringingpossibilities to study the interconnections inthe virtual space, thus enabling the expansionof the existing correlations in thisenvironment. The methodology for thedevelopment of the research was a literaturereview about webometrics and a case study ofthe websites of the federal public universitiesin the North and Midwest. The results show avery low number of interconnections in the tworegions, according to the indicators of visibilityand brightness. The study demonstrates thatthere is room for a greater connectivitybetween such institutions in order to increasecommunication between them on the web.

Informa??o & Informa??o , 2010, DOI: 10.5433/1981-8920.2010v15n1p55-67
Abstract: Como parte de uma pesquisa mais ampla a respeito da presen a das institui es federais de ensino superior brasileiras na Web, realizou-se uma análise das universidades da regi o Nordeste do país por meio da aplica o de diferentes indicadores webométricos: tamanho do sítio, visibilidade, fator de impacto Web - FIW, luminosidade e densidade da rede. Para a medi o do tamanho dos sítios Web e de sua visibilidade no mundo virtual, utilizou-se o motor de busca Yahoo e o fator de impacto foi calculado por meio de uma fórmula especialmente criada para este fim. A luminosidade destes sítios foi calculada tendo como ferramenta o programa mapeador Xenu Link Sleuth. A densidade da rede foi obtida também com a aplica o de uma fórmula. O programa Ucinet6 foi utilizado para a visualiza o das conex es entre os sítios das universidades da regi o. Os resultados demonstraram que as universidades maiores s o também aquelas mais acessadas e as menores s o as que costumam acessar mais websites. O fator de impacto n o apresentou resultados significativos quando aplicado a sítios Web e a densidade da rede das universidades federais da regi o Nordeste do Brasil mostrou-se muito baixa, o que representa um enorme potencial inexplorado no que diz respeito à conectividade destas institui es com seus pares neste ambiente.

Brazilian Journal of Information Science , 2007,
Abstract: Procura-se realizar uma análise webométrica dos sites acadêmicos latinoamericanos da área de Ciências Sociais por meio de três indicadores: visibilidade, luminosidade e densidade da rede. Para realizar tal análise lan ou-se m o do webmining, método que consiste na utiliza o de ferramentas adequadas para a extra o de informa es da Web. Para a mensura o da visibilidade dos sites optou-se pela busca avan ada do motor Alta Vista, para contabilizar a luminosidade lan ou-se m o do programa mapeador Link Xenu Steuth e para o cálculo da densidade da rede foram utilizados os programas Excel, Ucinet5 e NetDraw, que permitiram contabilizar os links, construir matrizes e visualizar as conex es das redes nacionais e internacionais. Os resultados obtidos com a pesquisa mostram que dos 174 sites analisados, os que aparecem nos primeiros lugares em rela o à visibilidade (os mais apontados ou citados) s o os brasileiros, aqueles que exibem as primeiras coloca es em luminosidade (os que mais apontam ou citam) s o os mexicanos e o país que demonstrou ter a maior densidade da rede (maior número de conex es entre os seus sites) foi o Peru. Por último, verificou-se, ainda, que o site que mais se conecta com sites de outros países é o da Facultad Latinoamericana de Ciencias Sociales de México (FLACSO-MX).

Brazilian Journal of Information Science , 2007,
Abstract: The purpose of this paper is to do a webometric analysis of academic sites of Latin-American Social Sciences applying three indicators: visibility, luminosity and network density. In order to undertake this analysis, we have used webmining, a method based on the use of tools that help in obtaining information from the Web. The search engine Alta Vista was employed to measure the visibility of websites. The mapping software Link Xenu Steuth was employed to calculate luminosity. Excel, Ucinet5 and NetDraw were employed to determine network density (they allowed us to estimate links, build up matrix and visualize connections among national and international networks). The results obtained in this research showed that within the 174 analyzed websites those which appear first in the ranking (the most linked or cited) are Brazilian, those which appear at the top in terms of luminosity (the ones that point or cite the most) are Mexican, and the country that appears to have the highest network density is Peru. Finally, we found out that the website with the highest number of links to websites from other countries is Facultad Latinoamericana de Ciencias Sociales of Mexico (FLACSO-MX).
Dynamical view of pair creation in uniform electric and magnetic fields
Tanji, Naoto
High Energy Physics - Phenomenology , 2008, DOI: 10.1016/j.aop.2009.03.012
Abstract: Pair creation in a uniform classical electromagnetic field (Schwinger mechanism) is studied focusing on the time evolution of the distribution of created particles. The time evolution of the distribution in time-dependent fields is also presented as well as effects of back reaction. Motivated by the Glasma flux tube, which may be formed at the initial stage of heavy-ion collisions, we investigate effects of a magnetic field parallel to an electric field, and find that the magnetic field makes the evolution of a fermion system faster.
Quark pair creation in color electric fields and effects of magnetic fields

Physics , 2010, DOI: 10.1016/j.aop.2010.03.012
Abstract: The time evolution of a system where a uniform and classical SU(3) color electric field and quantum fields of quarks are dynamically coupled with each other is studied focusing on non-perturbative pair creation and its back reaction. We characterize the color direction of the electric field in a gauge invariant way, and investigate its dependence. Momentum distributions of created quarks show plasma oscillation as well as quantum effects such as the Pauli blocking and interference. Pressure of the system is also calculated, and we show that pair creation moderates degree of anisotropy of pressure. Furthermore, enhancement of pair creation and induction of chiral charge under a color magnetic field which is parallel to the electric field are discussed.
