Today's society called information society, grows rapidly and undergoes changes in the sources of information under the Information Technology and Communication ("tics"), in this situation it is necessary to develop tools or reference sources that allow the (to) user (a) the accessibility and use of information. It systematized information on the Meritorious Citizen of the Fatherland and Honor that is Costa Rica, since 1847 to 2008, due to its contribution to culture, science, recreation, among others. The overall objective of this research was to make a work print and digital reference, which will collect each of the biographies and works written by (as) Benefactors (as) of the country and citizens (as) of Honor and to facilitate access to information and strengthen outreach conducted by the Library "Victor Manuel Sanabria Martínez" of the Legislature, through its publications, exhibitions and related activities, to publicize its documentary. The variables used for this investigation were:-sources (primary and secondary), Organization of information - tools in various documentation centers and libraries. This was carried out a questionnaire, which was structured in the Excel program, aimed at (as) directors (as) or officers (as) in different libraries and documentation centers, and visits to selected sites for search and selection information. It is important to spread this final graduation in different public and school libraries in the country, since history and culture rescues national, who gave identity to the Costa Rican people. The systematization made by a thematic CD-ROM, provide accessibility to all (as) the (as) citizens (as) who access the Internet through the website of the Legislative Assembly Library and other state institutions wishing through a hyperlink on your "web", to refer the same.

We can categorically state that the information is the main ingredient of the culture of a people. Defining information as a set of processed data that are needed, have value and meaning for individuals and for developing countries where data is any fact.The information could also be considered as an international resource indispensable. The scientific and technological development is a consequence of the relevant information is handled. The "heap" is a source of information that libraries must consider and integrate them because they give rise to more information and new technology. The need for improved information systems in recent years, it has become critical because the information data grows in quantity and complexity of organization. Consequently, some libraries have tried to coordinate functions, redistribute resources, identify needs and work together to give easier access to information

Background: The Medical Education Partnership Initiative, has helped to mitigate the digital divide in Africa. The aim of the study was to assess the level of access, attitude, and training concerning meaningful use of electronic resources and EBM among medical students at an African medical school. Methods: The study involved medical students at the University of Zimbabwe College of Health Sciences, Harare. The needs assessment tool consisted of a 21-question, paper-based, voluntary and anonymous survey. Results: A total of 61/67 (91%), responded to the survey. 60% of the medical students were ‘third-year medical students’. Among medical students, 85% of responders had access to digital medical resources, but 54% still preferred printed medical textbooks. Although 25% of responders had received training in EBM, but only 7% found it adequate. 98% of the participants did not receive formal training in journal club presentation or analytical reading of medical literature, but 77 % of them showed interest in learning these skills. Conclusion: Lack of training in EBM, journal club presentation and analytical reading skills have limited the impact of upgraded technology in enhancing the level of knowledge. This impact can be boosted by developing a curriculum with skills necessary in using EBM.

Means to automate the fact replace the man in their job functions for a man and machines automatic mechanism, ie documentary specialists in computer and computers are the cornerstone of any modern system of documentation and information. From this point of view immediately raises the problem of deciding what resources should be applied to solve the specific problem in each specific case. We will not let alone to propose quick fixes or recipes in order to decide what to do in any case. The solution depends on repeat for each particular problem. What we want is to move some points that can serve as a basis for reflection to help find the best solution possible, once the problem is defined correctly. The first thing to do before starting any automated system project is to define exactly the domain you want to cover and assess with greater precision possible importance.

In this dissertation, I explore information practices during life transition in the context of immigration. This study aims to understand how their unique personal, social, and life contexts shape immigration experiences, and how these diverse contexts are related to various information practices that they engage in to resolve daily information needs and achieve immigration goals. In my study I examined daily information needs and acquisition of Korean immigrant women. Data were collected through two interview sessions, diary entries on everyday information seeking up to three weeks, post-diary debriefing interviews to reveal contexts surrounding information practices, and observation sessions. My study shows that one’s accumulated experiences with information-related situations shape the person’s attitudes toward diverse information resources and habitual information practices. Both personal and social contexts surrounding immigrant women change during life transition and shape how they interpret their immigration experiences, what information they need to deal with both daily and long-term goals, and how they modify their information practices to obtain the relevant information in an unfamiliar information environment. Also, life transition of immigration entails changes in immigrant women’s social roles, which engender their daily responsibilities in the new society. These daily responsibilities motivate immigrant women’s everyday interactions with a variety of communities in order to exchange information and conduct their social roles in the new sociocultural environment. While immigrant women had common information needs around culture learning, social roles and associated responsibilities explain differences in their differing information needs and tend to direct daily information practices. The advancement of ICTs allows immigrant women to conduct their social roles in a remote city as well as to maintain multiple connections with both the heritage and host society. Limited cultural knowledge influences immigrant women’s evaluation and use of the obtained information as well as their acquisition of relevant information. This study provides understandings on the role of information during life transition as well as Korean immigrant women’s information practices.

This paper analyses the intermediary role of the technical bodies that support the use of budgetary and financial information by central government politicians in Portugal. The main findings show that information brokers are playing a central role in preparing this information in a credible, simple and understandable way. However, even if not intentionally, the information they present can be biased. Politicians need to be aware that the information brokers they rely on may not be giving them ‘neutral’ information.

Analysis of data without labels is commonly subject to scrutiny by unsupervised machine learning techniques. Such techniques provide more meaningful representations, useful for better understanding of a problem at hand, than by looking only at the data itself. Although abundant expert knowledge exists in many areas where unlabelled data is examined, such knowledge is rarely incorporated into automatic analysis. Incorporation of expert knowledge is frequently a matter of combining multiple data sources from disparate hypothetical spaces. In cases where such spaces belong to different data types, this task becomes even more challenging. In this paper we present a novel immune-inspired method that enables the fusion of such disparate types of data for a specific set of problems. We show that our method provides a better visual understanding of one hypothetical space with the help of data from another hypothetical space. We believe that our model has implications for the field of exploratory data analysis and knowledge discovery.

This paper proposes a principal-agent model between banks and firms with risk and asymmetric information. A mixed form of finance to firms is assumed. The capital structure of firms is a relevant cause for the final aggregate level of investment in the economy. In the model analyzed, there may be a separating equilibrium, which is not economically efficient, because aggregate investments fall short of the first-best level. Based on European firm-level data, an empirical model is presented which validates the result of the relevance of the capital structure of firms. The relative magnitude of equity in the capital structure makes a real difference to the profits obtained by firms in the economy.

Abstract Background: Communication is a basic tool in nursing, a crucial element of care. The quality of the interactions that take place between the nurse and the user/family influence their satisfaction and security felt with the care received. Objectives: To identify the communication skills and interpersonal relationship of nursing students in health care; identify the sociodemographic and academic variables influencing communication skills and interpersonal relationship of nursing students in health care. Methodology: Quantitative study, cross-sectional, descriptive and correlational. The data collection instrument was a questionnaire with questions concerning the socio-demographic and academic characterization; basic skills of interview and clinical communication in health care; learning of clinical communication skills and range of communication skills and interpersonal relationship. The sample consisted of 374 nursing students from two Portuguese schools. Results: The majority were female (80.5%), in the age group of 18-21 years. The students recognize the importance of clinical communication skills and interpersonal relations in nursing practice (82.4%); agreed on the teaching methods of communicational skills (54.3%). Evaluated their training in the area as good (71.7%). Age, semester and school influenced communication skills and interpersonal relationship of students (p <0.5) Conclusion: The results obtained allow us to state that the education / training of nursing student in the relational context is of fundamental importance in building capacity for competent professional practice.

Dietary fi bres (DFs) are essential components of the balanced diet. Even though the adequate level of their consumption can be ensured from several natural (e.g. fruit, vegetables, legumes) and ‘artifi cial’ sources (e.g. functional foods), the consumed levels are below the recommendations. To analyse the Hungarian and Romanian consumers’ knowledge level, their perceptions of the health benefi ts associated with fi bre, as well as the recognition of the potential information sources, a survey questionnaire was conducted with the total of 713 consumers. Results showed that the level of knowledge about DFs was not adequate. Internet was found to be widely used and identifi ed as one of the most appropriate information sources to encourage the consumption of DF. It was a favourable result that three-quarter of the respondents was interested in the topic of healthy food consumption; however, just less than half of them took into consideration the label information during their shopping decisions. To increase the consumption of DF and to support the responsibility and conscious consumer decisions steps must to be done (e.g. education of children, pointing out of the sources). For this purpose, modern information technology and communication channels fi tting to the consumers’ cultural and personal particularities can be utilized.
