Professional development and a discussion of the professional preparation provided by information and library science degree programs in public universities in Madrid, 2000-2005

A study was designed to determine how the degree programs in Information and library science available in 2000-2005 at the public universities of Madrid fit the tabour market needs of their students. The methodology used was the development of a questionnaire addressed to graduates. Although the number of surveys completed is not high (118), the authors believe that the results obtained permit a series of conclusions that may be extrapolated to the entire cohort.

Cultural heritage as a document: transdisciplinary reflections to new horizons in Information Science

The aim of this paper is to give an overview of the issues and actions on the Brazilian cultural heritage and then to discuss contributions as well as relationships that may be established from the principles of Information Science. The first item is concerned with the relationship between heritage and the concept of document, the second relates the documentary processes and the information scientist and finally, an approach of cultural heritage mediation and appropriation is presented.

Embryonic, Larval, and Juvenile Development of the Sea Biscuit Clypeaster subdepressus (Echinodermata: Clypeasteroida)

Sea biscuits and sand dollars diverged from other irregular echinoids approximately 55 million years ago and rapidly dispersed to oceans worldwide. A series of morphological changes were associated with the occupation of sand beds such as flattening of the body, shortening of primary spines, multiplication of podia, and retention of the lantern of Aristotle into adulthood. To investigate the developmental basis of such morphological changes we documented the ontogeny of Clypeaster subdepressus. We obtained gametes from adult specimens by KCl injection and raised the embryos at 26 degrees C. Ciliated blastulae hatched 7.5 h after sperm entry. During gastrulation the archenteron elongated continuously while ectodermal red-pigmented cells migrated synchronously to the apical plate. Pluteus larvae began to feed in 3 d and were similar to 20 d old at metamorphosis; starved larvae died 17 d after fertilization. Postlarval juveniles had neither mouth nor anus nor plates on the aboral side, except for the remnants of larval spicules, but their bilateral symmetry became evident after the resorption of larval tissues. Ossicles of the lantern were present and organized in 5 groups. Each group had 1 tooth, 2 demipyramids, and 2 epiphyses with a rotula in between. Early appendages consisted of 15 spines, 15 podia (2 types), and 5 sphaeridia. Podial types were distributed in accordance to Loven's rule and the first podium of each ambulacrum was not encircled by the skeleton. Seven days after metamorphosis juveniles began to feed by rasping sand grains with the lantern. Juveniles survived in laboratory cultures for similar to 9 months and died with <500 mu m wide, a single open sphaeridium per ambulacrum, aboral anus, and no differentiated food grooves or petaloids. Tracking the morphogenesis of early juveniles is a necessary step to elucidate the developmental mechanisms of echinoid growth and important groundwork to clarify homologies between irregular urchins.

From Offshore to Onshore: Multiple Origins of Shallow-Water Corals from Deep-Sea Ancestors

Shallow-water tropical reefs and the deep sea represent the two most diverse marine environments. Understanding the origin and diversification of this biodiversity is a major quest in ecology and evolution. The most prominent and well-supported explanation, articulated since the first explorations of the deep sea, holds that benthic marine fauna originated in shallow, onshore environments, and diversified into deeper waters. In contrast, evidence that groups of marine organisms originated in the deep sea is limited, and the possibility that deep-water taxa have contributed to the formation of shallow-water communities remains untested with phylogenetic methods. Here we show that stylasterid corals (Cnidaria: Hydrozoa: Stylasteridae)-the second most diverse group of hard corals-originated and diversified extensively in the deep sea, and subsequently invaded shallow waters. Our phylogenetic results show that deep-water stylasterid corals have invaded the shallow-water tropics three times, with one additional invasion of the shallow-water temperate zone. Our results also show that anti-predatory innovations arose in the deep sea, but were not involved in the shallow-water invasions. These findings are the first robust evidence that an important group of tropical shallow-water marine animals evolved from deep-water ancestors.

Influências metodológicas na mensuração de impacto: o caso das Memórias do Instituto Oswaldo Cruz e sua "qualificação"

In recent years, the availabity of citation indexes for evaluation of Brazilian scientific production has increased. The comparison between the results of the methodologies used to estimate indicators in the citation reports of SciELO database and in Journal Citation Reports (ISI-Thomson Scientific) made it possible to evaluate implications associated to the Brazilian scientific policy (Qualis), regarding some specific criteria. A period of 10 years was considered, taking into account two bibliometric indicators (the total of citations in a year and the Impact Factor) of the journal Memorias do Instituto Oswaldo Cruz, which is indexed in both indexes. The correction of the indicators associated to this journal showed that the differences in the citation indexed were more expressive in 2001, having decreased in the last years. This reduction gives credibility to both databases, validating their systems for the production of bibliometric indicators.

Change and Aging Senescence as an Adaptation

Understanding why we age is a long-lived open problem in evolutionary biology. Aging is prejudicial to the individual, and evolutionary forces should prevent it, but many species show signs of senescence as individuals age. Here, I will propose a model for aging based on assumptions that are compatible with evolutionary theory: i) competition is between individuals; ii) there is some degree of locality, so quite often competition will be between parents and their progeny; iii) optimal conditions are not stationary, and mutation helps each species to keep competitive. When conditions change, a senescent species can drive immortal competitors to extinction. This counter-intuitive result arises from the pruning caused by the death of elder individuals. When there is change and mutation, each generation is slightly better adapted to the new conditions, but some older individuals survive by chance. Senescence can eliminate those from the genetic pool. Even though individual selection forces can sometimes win over group selection ones, it is not exactly the individual that is selected but its lineage. While senescence damages the individuals and has an evolutionary cost, it has a benefit of its own. It allows each lineage to adapt faster to changing conditions. We age because the world changes.

A institucionalização da ciência da informação no Brasil sob a ótica da evolução quantitativa dos cursos de graduação na área

The study describes the process of scientific institutionalization of Information Science in Brazil, from quantitative analysis of the development of undergraduate courses in the area. As body of research, it considers the following courses: Librarianship, Archival Science, Museology, Information Science and Management one, created between the years 1910 and 2008. It is noted that the growth trend of the quantity of courses reflects the importance given to information in the current context. However, the diversity of nomenclature and conceptual differences in the theoretical field illustrate the epistemological fragility of the area, as well as the search for greater professional visibility in society.

Reflexões acerca das relções entre representação temática e descritiva

It presents the importance of integrating the thematic representation into the descriptive one, revealing the theoretical and practical aspects of these disciplines and tracing relationships between them. The goal of this work is to discuss the conceptual models Functional Requirements for Bibliographic Records (FRBR), Functional Requirements for Subject Authority Data (FRAD) and Functional Requirements for Subject Authority Data (FRSAD), illustrating them with the work of information search done by the user on a system. It emphasizes the importance of specific knowledge, without losing the viewpoint of both areas as complementary ones. The theoretical and methodological approach is based on the theoretical and conceptual research on the discussed thematics so as to analyze the facts available in the literature as well as to consider their practical applicability. We conclude that there is a happy and necessary integration between the thematic and descriptive representations that optimizes the informational access, though the second discipline is still regarded by many as pure physical description in manual catalogs.

Documentos convencionais e não convencionais em administração, ciências contábeis e economia: estudo sobre sua utilização pelos alunos de graduação

The recommended bibliographical references for the development of scientific research are those published by scientific journals. In spite of this recommendation, the use of non conventional documents by undergraduate students has been increasing. This paper, developed as a survey with 145 students of Administration, Accounting and Economics, characterizes the use these documents and analyzes teaching strategies supported in the use of non conventional documents.

ALFABETIZAÇÃO DIGITAL: proposição de parâmetros metodológicos em competência informacional

Much has been discussed about Digital Literacy, but it is quite obscure the identification of the skills required to develop such process. This study was done towards an integration of the Digital Literacy process to the specific informational skills a person may dominate, search, retrieve and use information efficiently, in its professional, academic or personal life. The main objective of this work is to propose methodological parameters for training in informational skills. Otherwise, the specific objectives are associated to the supposition and identification of the desired skills of the Digital Literacy program participants. The methodological procedures applied to the research are of exploratory character, and to do so two tools are used: the literature research and case studies. Besides having the methodology in structured information competence, the study points out to the fact that the country is too far from what is desired concerning development and employment of Digital Literacy programs consistent enough to support the teaching and learning of searching, recovering and using of information by the participants. Therefore, it is essential to create programs that provide not only machinery, but motivate individuals to develop informational skills to help in the learning process.

Students' collective knowledge construction in the virtual learning environment ""ToLigado - your school interactive newspaper""

Introduction. The ToLigado Project - Your School Interactive Newspaper is an interactive virtual learning environment conceived, developed, implemented and supported by researchers at the School of the Future Research Laboratory of the University of Sao Paulo, Brazil. Method. This virtual learning environment aims to motivate trans-disciplinary research among public school students and teachers in 2,931 schools equipped with Internet-access computer rooms. Within this virtual community, students produce collective multimedia research documents that are immediately published in the portal. The project also aims to increase students' autonomy for research, collaborative work and Web authorship. Main sections of the portal are presented and described. Results. Partial results of the first two years' implementation are presented and indicate a strong motivation among students to produce knowledge despite the fragile hardware and software infrastructure at the time. Discussion. In this new environment, students should be seen as 'knowledge architects' and teachers as facilitators, or 'curiosity managers'. The ToLigado portal may constitute a repository for future studies regarding student attitudes in virtual learning environments, students' behaviour as 'authors', Web authorship involving collective knowledge production, teachers' behaviour as facilitators, and virtual learning environments as digital repositories of students' knowledge construction and social capital in virtual learning communities.

A influência da Jean-Claude Gardin e a linha francesa na evolução do conceito de linguagem documentária

Bibliographic review study on the evolution of Documentary Languages and its field of study, the documentary linguistics. Based upon the researches developed by the french approach in Europe notably by jean-claude gardin and in brazil by grupo temma. It is proposes a framework of the main characteristics of documentary languages having the appropriation of the structural linguistics by the documentation as a focus. It anayses the evolution of the denomination of documentary languages, their functions, and it compares both approaches.

Sociedade da informação: avanços e retrocessos no acesso e no uso da informação

The Information Society (IS) may be taken as a geopolitical organization which started after the Third Industrial Revolution, having direct impact on the use of information and Information and Communication Technologies (ICT). The expression arose as techno-social paradigm change in the post-industrial society, aiming to use information as currency to the society-in-progress at that time. In Brazil it has become stronger with the Programa Sociedade da Informacao no Brasil-Livro Verde, lunched by the Ministerio da Ciencia e Tecnologia, in September 2000 without any discussion with the civil society to formulate the main document. Our main goal in this article is to discuss the Information Society in contemporary times, and also the organized and conscious use of information, looking for key-concepts to a better understanding of it, from some topics as digital inclusion-exclusion to the use of digital informational resources.

Introdução ao uso dos protocolos SRU/SRW: ferramentas para a catalogação cooperativa

In this article the use of Search and Retrieve URL (SRU) / Search and Retrieve Web Service (SRW) protocols, both developed and maintained by the Library of Congress in the United States, is presented and discussed. The SRU/SRW is a new draft protocol based on the already widespread Z39.50 protocol, whose purpose is to facilitate the development of solutions for shared cooperative cataloging of bibliographic information. Some examples of applications are also shown and the lack of production on the subject in specialized journals is pointed out.

The impact of obstructive sleep apnea on metabolic and inflammatory markers in consecutive patients with metabolic syndrome

Background: Obstructive Sleep Apnea (OSA) is tightly linked to some components of Metabolic Syndrome (MetS). However, most of the evidence evaluated individual components of the MetS or patients with a diagnosis of OSA that were referred for sleep studies due to sleep complaints. Therefore, it is not clear whether OSA exacerbates the metabolic abnormalities in a representative sample of patients with MetS. Methodology/Principal Findings: We studied 152 consecutive patients (age 48 +/- 9 years, body mass index 32.3 +/- 3.4 Kg/m(2)) newly diagnosed with MetS (Adult Treatment Panel III). All participants underwent standard polysomnography irrespective of sleep complaints, and laboratory measurements (glucose, lipid profile, uric acid and C-reactive protein). The prevalence of OSA (apnea-hypopnea index >= 15 events per hour of sleep) was 60.5%. Patients with OSA exhibited significantly higher levels of blood pressure, glucose, triglycerides, cholesterol, LDL, cholesterol/HDL ratio, triglycerides/HDL ratio, uric acid and C-reactive protein than patients without OSA. OSA was independently associated with 2 MetS criteria: triglycerides: OR: 3.26 (1.47-7.21) and glucose: OR: 2.31 (1.12-4.80). OSA was also independently associated with increased cholesterol/HDL ratio: OR: 2.38 (1.08-5.24), uric acid: OR: 4.19 (1.70-10.35) and C-reactive protein: OR: 6.10 (2.64-14.11). Indices of sleep apnea severity, apnea-hypopnea index and minimum oxygen saturation, were independently associated with increased levels of triglycerides, glucose as well as cholesterol/HDL ratio, uric acid and C-reactive protein. Excessive daytime sleepiness had no effect on the metabolic and inflammatory parameters. Conclusions/Significance: Unrecognized OSA is common in consecutive patients with MetS. OSA may contribute to metabolic dysregulation and systemic inflammation in patients with MetS, regardless of symptoms of daytime sleepiness.
