Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Na Colômbia ocorrem 787 espécies de anfíbios. Por causa da preocupação com o estado de conservação de muitas dessas espécies, tem se sugerido que na Colômbia deveriam-se priorizar as pesquisas em taxonomia e ecologia em regiões sub-amostradas a fim de intensificar o conhecimento e conservação dos anfíbios colombianos. Baseados em uma análise cienciométrica de 319 trabalhos sobre a ecologia dos anfíbios colombianos publicados entre 1840 e 2014 (No Capítulo 1), identificamos as tendências nos esforços realizados em distintos temas de pesquisa, e a distribuição regional e taxonômica desses estudos. A maioria dos estudos (67%) foi realizada na região Andina colombiana em comparação com outras regiões naturais da Colômbia. Apenas 46% das espécies de anfíbios ocorrendo na Colômbia foi tratada nos estudos analizados, e a maioria (58%) delas é da região Andina. Entre as publicações analizadas identificamos 14 temas de pesquisa em ecologia, dos quais ecologia reprodutiva (26%), conservação de espécies (23%) e dieta (14%) foram os mais pesquisados. Nossos dados mostraram que na Colômbia há um considerável avanço na pesquisa sobre a ecologia dos anfíbios do país, mas ainda são necessários esforços para cobrir muitos vazios de informação para muitas regiões e para muitas espécies de anfíbios que possuem dados incipientes. No sudoeste da Cordilheira Ocidental colombiana há pouca informação ecológica sobre os anfíbios ali ocorrendo. A fim de saber alguns aspectos ecológicos dessas espécies, desenvolvimos três estudos sobre a diversidade e ecologia de anfíbios presentes na Reserva Natural Río Ñambí (a seguir RNRÑ). No Capítulo 2 apresentamos uma análise sistemática do gênero Andinophryne (Família Bufonidae), composto por três espécies, A. atelopoides, A. colomai (presente na RNRÑ) e A. olallai. As filogenias mostraram que Andinophryne está incorporado dentro de Rhaebo. Portanto, sinonimizamos Andinophryne sob Rhaebo e discutimos as sinapomorfias morfológicas putativas para Rhaebo. Além, fornecemos informações ecológicas e sobre o estado de conservação das três espécies incluídas na nova combinação taxonômica. No Capítulo 3 apresentamos uma lista de 19 espécies de anfíbios pertencentes a oito famílias, com uma dominância numérica da família Craugastoridae e do gênero Pristimantis. As espécies com a maior abundância relativa (> 25%) foram Pristimantis labiosus e P. verecundus. Sete diferentes modos de reprodução foram reconhecidos, com a maioria das espécies (68%) possuindo desenvolvimento direto de ovos. Cinco (26%) das espécies registradas estão classificadas dentro das categorias de maior ameaça de extinção. Reportamos para sete espécies a extensão da faixa de distribuição geográfica latitudinal na Colômbia. No Capítulo 4 comparamos a dieta de jovens e adultos de P. labiosus para identificar se houve uma mudança ontogenética no tamanho de presa consumido com o aumento na largura da boca. A dieta foi composta por 19 categorias de presas (> artrópodes), com as duas classes de idade consumindo um similar espectro de categorias. Os jovens têm um nicho trófico maior (0,45) do que os adultos (0,25), com uma sobreposição de nicho relativamente baixa (0,39) entre eles. Apesar da diferencia na largura da boca entre jovens e adultos, não houve uma correspondente mudança ontogenética no tamanho de presa consumida. Consideramos P. labiosus como um predador generalista que parece consumer uma ampla gama de tipos e tamanhos de presas / Colombia harbors 787 species of amphibians. Because of concerns with the conservation status of many of these species, it has been suggested that in Colombia should prioritize research in taxonomy and ecology in undersampled regions in order to enhance the knowledge and conservation of Colombian amphibians. Based on a scientometric analysis of 319 works on ecology of Colombian amphibians published between 1840 and 2014 (Chapter 1), we identified trends in the efforts made in different research topics, and both regional and taxonomic distribution of these studies. Most studies (67%) was conducted in the Colombian Andean region compared to other natural regions of Colombia. Only 46% of amphibian species occurring in Colombia was included in the reviewed studies, and the most of them (58%) is from the Andean region. Among the reviewed publications, we identified 14 research topics in ecology, of which reproductive ecology (26%), species conservation (23%), and diet (14%) were the most investigated. Our data showed that in Colombia, there is a considerable advance in research on amphibian ecology, but we need further efforts to fill many gaps in information for many regions and for many amphibian species possessing incipient data. In southwestern of the Colombian western Andes there is little information about the species occurring there. In order to know some ecological aspects of these species, we conducted three studies on diversity and ecology of the amphibians present in the Reserva Natural Río Ñambí (hereafter RNRÑ). In the Chapter 2, we show an analysis of the systematics of the genus Andinophryne (Family Bufonidae), composed by three species, A. atelopoides, A. colomai (present in the RNRÑ) and A. olallai. The phylogenies showed that Andinophryne is embedded within Rhaebo. Therefore, we synonymize Andinophryne under Rhaebo and we discussed the putative morphological synapomorphies for Rhaebo. In addition, we provide ecological informations and on the conservation status of the three species included in the new taxonomic combination. In the Chapter 3, we show a list of 19 amphibian species from eight families, with a numerical dominance of the Family Craugastoridae and of the genus Pristimantis. The species with the highest relative abundance (>25%) were Pristimantis labiosus and P. verecundus. Seven different reproductive modes were recognized, with most species (68%) presented direct development of eggs. Five (26%) of the species recorded are classified in the categories of greatest threat of extinction. We report for seven species an extension of the latitudinal distribution range in Colombia. In the Chapter 4, we compared the diet of juveniles and adults of P. labiosus in order to identify if there was an ontogenetic shift in the prey size consumed as mouth width increases. The diet was composed of 19 prey categories (> arthropods), and the two age-classes consumed a similar array of prey categories. Juveniles had a broader trophic niche (0.57) than adults (0.25), with a relatively low trophic overlap among them (0.39). Although we found differences in mouth width between juveniles and adults, we did not observe a corresponding ontogenetic shift in prey size consumption. We consider that P. labiosus is a generalist predator, consuming a wide range of prey types and sizes

Analisa os objetivos e propostas de organização da informação desenvolvidos pelo Movimento Bibliográfico e indica sua influência na Ciência da Informação. Esta pesquisa de natureza exploratória, realizada através de levantamento, revisão e análise bibliográficos, investiga o pensamento de Paul Otlet, Wilhelm Ostwald, H. G. Wells, John Cotton Dana e Watson Davis, expoentes do Movimento Bibliográfico, no contexto da modernidade. O Movimento Bibliográfico caracterizava-se por sua pluralidade e buscava responder às alterações no mundo informacional decorrentes da modernidade. O movimento atribuía à informação a potencialidade de transformação dos indivíduos e, portanto, transformou o foco dos serviços de informação da preservação para o acesso, procurando organizar acervos em função de seus conteúdos. O desenvolvimento tecnológico contemporâneo ao movimento fez com que seus expoentes enfatizassem a aplicação de novas tecnologias ao processo de disseminação da informação, pois entendiam que este seria facilitado e agilizado. A Ciência da Informação herdou seu papel social parcialmente do Movimento Bibliográfico, objetivando a organização da informação para seu acesso, e compartilha com o movimento a perspectiva de emprego de alta tecnologia na disseminação da informação. O espírito do tempo no qual se originou o Movimento Bibliográfico levou ao aparecimento de um ideário comum que permitiu a elaboração de propostas similares, entretanto, não se descarta a influência mútua entre os indivíduos analisados na pesquisa. Apesar de sua especificidade histórica, o Movimento Bibliográfico compartilha com a Ciência da Informação o ideário informacional moderno e a relação deste com a cultura. Conclui-se que a cultura da informação contemporânea e aquela do movimento pesquisado apresentam diferenças, porém são culturas que se entrelaçam; muitos de seus problemas sendo semelhantes e necessitando soluções similares. / Analyses the objectives and proposals of information organisation developed by the Bibliographic Movement, and indicates its influence in Information Science. This exploratory research, accomplished through bibliographic survey, literature review, and analysis, investigates in the context of modernity the ideas of Bibliographic Movement exponents Paul Otlet, Wilhelm Ostwald, H. G. Wells, John Cotton Dana, and Watson Davis. The Bibliographic Movement was characterized by its plurality, and aimed to respond to modernity\'s effects in the information world. The movement attributed to information the potentiality of individual transformation. Therefore, it changed the focus of information services from preservation to access, and pursued the organisation of collections according to its contents. The development of technology made the Bibliographic Movement exponents emphasise the application of new technologies to the process of information dissemination in order to facilitate and accelerate it. Information Science inherited its social role partially from the Bibliographic Movement, and aims at organising information so that it can be accessed. Information Science also shares with the movement the perspective of employing high technology to disseminate information. The Zeitgeist that gave rise to the Bibliographic Movement led to a common set of ideas and allowed the elaboration of similar proposals for the organisation of information. However, it is not discarded the probability of mutual influence between the individuals analysed. Despite its historical specificity the Bibliographic Movement shares with Information Science modern ideas and its relation to culture. It is concluded that the current information culture and the information culture of the Bibliographic Movement have differences, notwithstanding, they are entwined cultures and many of their problems are similar and need similar solutions

Introdução: Muito se tem discutido sobre o desafio de aumentar o impacto das publicações brasileiras. Comparado com outros países, o Brasil possui alta taxa de publicação, mas com baixo índice de citação por documento. Enquanto instituições de fomento e de pesquisa propõem a cooperação internacional como meio de aumentar o impacto das publicações científicas, os editores de periódicos contestam essa exigência. Objetivo: Avaliar se nos periódicos brasileiros de medicina, o número de citações recebidas é influenciado pelo tipo de afiliação dos autores e por outras variáveis relacionadas ao documento ou ao periódico. Métodos: Foram analisados 61 periódicos de medicina publicados no Brasil em 2012, utilizando o SCImago e o Scopus para a extração dos artigos e seus dados. O número de citações de um documento num período de cinco anos foi analisado de acordo com a afiliação dos autores (nacional, internacional ou colaboração), idioma e tipo do documento, indicador SCImago e categoria do assunto do periódico. Resultados: Análises univariadas mostraram que todas as variáveis testadas influenciaram o número de citações recebidas. Após ajuste de covariáveis pela análise multivariada observamos aumento de citações em 0,17 (IC 95%: 0,094-0,246) para documentos com afiliação em colaboração quando comparado à afiliação nacional. Aumento significativo no número de citações foram observados em documentos em idioma bilíngue (Inglês e Português) 0,329 (IC 95%: 0,256-0,402) e apenas em Inglês 0,158 (IC 95%: 0,086-0,231) quando comparado a documentos em português, do tipo artigo 1,716 (IC 95%: 1,410-2,021) e artigo de Revisão 2,931 (IC 95%: 2,618-3,245) quando comparados a artigo no prelo e que possuem categoria de assunto Hematologia 1,280 (IC 95%: 1,019-1,540), entre outros, quando comparado ao assunto geriatria e gerontologia. Conclusão: Documentos com autoria em colaboração, aumentaram, de modo discreto, o índice de citação nos periódicos de interesse, quando comparados aos de autoria nacional. Idioma, tipo do documento, indicador Scimago (cites per doc - 2 years) e categoria do assunto do periódico influenciaram significantemente o número de citações recebidas / Introduction: The challenge of increasing the impact of Brazilian science has been much discussed. Compared with other countries, Brazil has a high publication rate, but with low citation index per document. While sponsoring and research institutions are proposing international cooperation as a means of increasing the impact of science, journal editors question this demand. Objective: To evaluate whether, in Brazilian medical journals, the number of received citations is influenced by the type of authors affiliation and other variables related to the document or to the journal. Methods: A total of 61 medical journals published in Brazil in 2012 were analyzed, SCImago and Scopus were used to extract the articles and their data. The number of citations of a document over five years was analyzed according to the authors\' affiliation (national, international or in collaboration), language and document type, SCImago index and journal subject category. Results: Univariate analyses showed that all tested variables influenced the number of received citations. After adjusting for covariates by multivariate analysis, we observed an increase of citations in 0.17 (95% CI: 0.094-0.246) for documents with affiliation in collaboration when compared to national affiliation. A significant increase in the number of citations was observed in bilingual documents (English and Portuguese) 0.329 (95% CI: 0.256-0.402) and only English 0.158 (95% CI: 0.086-0.231) when compared to documents in Portuguese, document type: Article 1.716 (95% CI: 1.410-2.021) and Review 2.931 (95% CI: 2.618-3.245) when compared to Article-in-Press and that have subject category Hematology 1.280 (95% CI: 1.019-1.540), among others, when compared to geriatrics and gerontology. Conclusion: Documents with authorship in collaboration increased, in a discreet way, the citation index in journals of interest, when compared to those with national authorship. Language, document type, SCImago index (cites per doc 2 years) and journal subject category significantly influenced the number of received citations

The purpose of this study was to investigate the use of electronic databases by postgraduate students in the Faculty of Science and Agriculture at the University of KwaZulu-Natal, Pietermaritzburg, with a view to proposing a set of recommendations based on the findings that would contribute to a more effective use of these databases. The study focussed on the use students made of electronic databases provided by the University of KwaZulu-Natal, Pietermaritzburg Library and any other electronic databases which provided information and were needed for their studies. The study population consisted of 500 registered postgraduate students. The survey instrument used to elicit data was a self-administered questionnaire that was distributed to a sample population of 100 postgraduate students. The questionnaire sought to establish if postgraduate students used electronic databases, which electronic databases postgraduate students used and the reasons for their choice, to identify problems postgraduate students encountered, how students became aware of the databases and how often they used the available databases. A total of 65 postgraduate students responded, a response rate of 65%. The results were analysed in terms of frequency responses and they are graphically displayed in the form of tables and graphs. The study found that postgraduate students did use the electronic databases, but a few of the databases were not used. A number of problems were experienced when using the databases. Students became aware of the availability of electronic databases from a variety of sources such as friends, library orientation programmes and academic staff. Search engines were identified as a resource that was very popular with almost all the students. There was a need for training on use of the databases and a need for improving access for all campus and off-campus users. Recommendations for action and further research, based on the conclusions of the study, are made. / Thesis (M.I.S.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.

In South Africa, government (Mbeki 1996:37) and educators (SAIDE Report 1998:9) have expressed concern over the provision of microcomputers for learners. Their provision to schools would allow their effective use across the curriculum and enhance education. This study investigated the role of microcomputers as information retrieval tools in the 1997 schools' Water Audit projects in the greater Pietermaritzburg area. The study considered, firstly, a discussion of environmental education with emphasis on water conservation, and secondly the Water Audit projects. An overview of issues relating to microcomputer systems as information retrieval tools in education was presented. A descriptive survey method was employed for the study, with questionnaires as the data collection technique. Thirty out of 40 teachers/school project co-ordinators were sampled, with a 24 (80%) response. Twenty percent of 550 pupils who participated in the projects also responded. Data was presented by the use of tables. The study revealed an unequal availability of microcomputers among the schools in the departments of education, as they existed prior to 1994, that participated in the projects. Findings also revealed that only a minority of pupils used the microcomputer system for information retrieval during the projects. The use of hard copy sources was significantly high within the departments. A high number of pupils who used the microcomputer found it useful. A higher number that used hard copy sources found them useful. Training of pupils to acquire computer and information skills was inadequate. Major problems encountered during the projects included congestion, lack of computer skills on the part of both teachers and pupils and inadequate training of participants. The study found infrastructural backlogs and logistical problems as hindrances to the delivery of education in South Africa using microcomputers. Non-involvement of media teachers negatively impacted on the results of the projects. It was recommended that schools without microcomputers liaise with donor agencies to acquire microcomputers, while government initiates policies to address the issue of equity. Educators and media teachers should be given concerted training in computer and information skills, as training underpins the use of microcomputers in an information age school. / Thesis (MIS)-University of Natal, Pietermaritzburg, 1999.

Magister Library and Information Studies - MLIS / Although Resource Description and Access (RDA) has been discussed extensively amongst the ranks of cataloguers internationally, no research on the perceptions of South African cataloguers was available at the time of this research. The aim of this study was to determine how well RDA was faring during the study's timeframe, to give a detailed description regarding cataloguer perceptions within a higher education setting in South Africa. Furthermore, to determine whether the implementation of RDA has overcome most of the limitations that AACR2 had within a digital environment, to identify advantages and/or perceived limitations of RDA as well as to assist cataloguers to adopt and implement the new standard effectively. The study employed a qualitative research design assisted by a phenomenological philosophy to gain insight into how cataloguers experienced the implementation and adoption of RDA by means of two concurrent web-based questionnaires. The study concluded that higher education cataloguing professionals residing in the Western Cape were decidedly positive towards the new cataloguing standard. Although there were some initial reservations, they were overcome to such an extent that ultimately no real limitations were identified, and that RDA has indeed overcome most of the limitations displayed by AACR2. Many advantages of RDA were identified, and participants expressed excitement about the future capabilities of RDA as it continues toward a link-data milieu, making library metadata more easily available. As this research has revealed a distinctly positive attitude from cataloguers' two main matters for future research remains, being: ? Why South African participants in this study voiced almost no perceived limitations to RDA as a cataloguing standard. Future research might be able to relay information regarding this trend, especially in the light that it was not a global phenomenon. ? A deeper look might have to be taken at how participants' experienced RDA training as this phenomenon might be closely linked to the reasons why the participants did not mention more limitations.

Le catalogue occupe une place privilégiée dans l’offre de service des bibliothèques universitaires, pivot de l’intermédiation. Depuis 10 ans, il traverse une crise grave, voyant les usagers le délaisser à la faveur des moteurs de recherche généralistes. Le web, plus qu’un sérieux concurrent, devance aujourd’hui les systèmes d’information documentaires, et devient le point d’entrée principal pour la recherche d’information. Les bibliothèques tentent de structurer un espace documentaire qui soit habité par les usagers, au sein duquel se développe l’offre de service, mais celle-ci se présente encore comme une série de silos inertes, sans grande possibilité de navigation, malgré de considérables efforts d’ingénierie et des pistes d’évolution vers les outils de découverte. La profession, consciente de cette crise profonde, après avoir accusé les remous occasionnés par la dimension disruptive du numérique, cherche des moyens pour adapter et diversifier son offre, fluidifier la diffusion de l’information, et se réinvente un rôle d’intermédiation en cherchant à tirer profit des nouvelles pratiques des usagers, de leurs nouvelles attentes, et de nouvelles perspectives. Les bibliothèques placent leur espoir dans de nouveaux modèles de données, tentent d’y ajouter un niveau d’abstraction favorisant les liaisons avec l’univers de la connaissance. L’évolution vers le web sémantique semble une opportunité à saisir pour valoriser les collections et les rendre exploitables dans un autre contexte, au prix d’importants efforts que cette analyse tente de mesurer. Une approche constructiviste fondée sur l’observation participante et le recueil de données offre une vision issue de l’intérieur de la communauté des bibliothèques sur l’évolution des catalogues et des outils d’intermédiation, et ouvre des perspectives sur leurs enjeux. / The catalog takes up a special position in the supply of services of academic libraries, as a pivot for the intermediary between users and information professionals who carry the responsibility for building up collections. For 10 years, through a serious crisis, they’ve been seeing their patrons preferring the general or commercial search engines. The Web is more than a serious competitor today, ahead of the document information systems, and became the main access point for information retrieval. Libraries are trying to structure an information space that is temporarily or permanently inhabited by users, in which the service offering is developed, but it is still presented as a series of silos, with few opportunities of navigation between them despite considerable engineering efforts and a perspective of evolution towards discovery tools. The profession, having become aware of this deep crisis after accusing eddies caused by the breakdown of the digital switch, looking for ways to adapt and diversify its offering, streamlines the dissemination of information, and reinvents its roles, trying to take advantage of new practices of users, new expectations and new prospects. Libraries put their hope in new data models, trying to add a level of abstraction promoting links with the world of knowledge. The evolution towards the Semantic Web seems to be a valuable opportunity to enhance the collections and make them usable in another context, at the expense of significant efforts sized up by this analysis. A constructivist approach based on participant observation and data collection offers a vision of the outcome within the library community on the development of catalogs and intermediation tools, and an outlook on their issues.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) / O objetivo geral desta dissertação foi analisar o perfil das publicações realizadas sobre capital natural na região metropolitana de Curitiba (RMC). A pesquisa foi baseada no modelo analítico proposto por Meadows, na abordagem dos três capitais (capital natural, capital social e capital construído), utilizando-se especificamente da “lente" capital natural. Tal análise buscará estabelecer relações e correlações entre a produção científica e o contexto territorial escolhido, demonstrando a forma como o capital natural da região é retratado dentro da produção científica sobre a mesma. Como metodologia, a pesquisa se baseia na revisão sistemática e na análise de conteúdo, utilizando-se de método misto para caracterizar quantitativa e qualitativamente a produção científica realizada na RMC no período de 1992 à 2017. A partir da categorização do capital natural em oito categorias, foi possível inferir sobre as principais tendências temáticas e temporais de pesquisa, além de avaliar este perfil a partir dos indicadores de qualidade, fator de impacto, SJR e SNIP. Notou-se uma maior tendência temática sobre o tema biodiversidade, justificado pelo elevado número de mananciais e remanescentes florestais na região, porém quando observado o número de citações as publicações sobre ar/clima possuem maior visibilidade na comunidade científica. / The general objective of this dissertation was to analyze the profile of publications on natural capital in the metropolitan region of Curitiba (RMC). The research was based on the analytical model proposed by Meadows, in the approach of the three capitals (natural capital, social capital and built capital), using specifically the "lens" natural capital. This analysis will seek to establish relationships and correlations between the scientific production and the chosen territorial context, demonstrating how the natural capital of the region is portrayed within the scientific production on the same. As a methodology, the research is based on systematic review and content analysis, using a mixed method to quantitatively and qualitatively characterize the scientific production carried out in the MRC from 1992 to 2017. From the categorization of natural capital into eight categories , it was possible to infer about the main thematic and temporal trends of research, besides evaluating this profile from the indicators of quality, impact factor, SJR and SNIP. There was a greater thematic tendency on the biodiversity theme, justified by the high number of sources and forest remnants in the region, but when the number of citations is observed, air / climate publications have greater visibility in the scientific community.

There was a greater thematic tendency on the biodiversity theme, justified by the high number of sources and forest remnants in the region, but when the number of citations is observed, air / climate publications have greater visibility in the scientific community.
