Serviço de Referência Virtual: implantação do serviço de chat

Introduction: With the invention of the Internet and the Collaborative Web, libraries had to rethink the way to offer their services. Thus, the U.S. libraries began a search for technological innovations in an effort to bring the library to the user through features that patrons commonly use. The Virtual Reference Service (VRS) through chat and reference services via videoconferencing are features that derived from this search. Objective: This article aims to outline the implementation process of Virtual Reference Services (SRV) libraries in American universities, particularly those for chat, as well as presenting the successful Brazilian experience. This paper also discusses factors to be considered for implementing virtual reference service via chat for libraries wishing to offer the service. Methodology: The research methodology is based on a theoretical search on international and national literature on the subject. The methodology also includes participant observation. Results: In Brazil the implementation of SRV in some university libraries has occurred and according to these institutions, the SRV is a service that benefits the community and puts the library in line with the demands of information technology and communication. Conclusions: It is concluded that online SRV is appropriate to the reality of university libraries in Brazil, since the institutions that offer the service have positive results from their assessments and believe they are adding value to their library.

A internet como ferramenta de mediação no acervo artístico-cultural dos Palácios do Governo do Estado de São Paulo

This research focuses on methods and strategies for educational-based digital tools, aimed at the public school. Thus, we present possibilities, and the main actions of the national museum institutions in several online educational services that exemplify some forms of virtual mediation in order to verify the relevance of using these tools. The study discusses the need for museums to follow the advance of new technologies to engage and retain the public school, consisting of a highly connected generation with new technologies. It also brings a brief overview of the evolution of the museum in the Western world and presents the formation and nature of art collections that comprise the Artistic-Cultural Collection of the Governmental Palaces of the State of São Paulo, focusing on the management policy of each period, highlighting the educational program and the relationship with the website. As a practical exercise, the research presented suggests applying a form of mediation for the virtual site of Artistic-Cultural Collection of the Governmental Palaces to extend relations sector educational institution for the virtual context

Classificação de workflows baseados em web services

Over the last decades changes have occurred in communication within and between enterprises, made easier by technologies suchas E-commerce, Internet, ERP systems and remote meetings and there was a rapid progress in network technology, which has changed the way business is done. A standardized way to offer services over the internet is using web services. Web services are a kind of remote procedure call and are generally used to integrate systems, independent of language, both client and server. It is common to use several web services run in sequence to perform a business process. To this type of process, gives the name of workflow. Thus, Web services are the primary components of workflows. A tool that provides a way of visualizing the behavior of a workflow can assist the administrator and is required. The present work presents the development of a tool that allows the administrator to classify visually services components and evaluate their importance in the final performance of a workflow. As proof of concept we used several virtual servers and computers where each computer has received a set of web services. A proxy was added between each call of workflows collecting relevant information and storing them in a database for later analysis. The analysis was based on Quality of Service parameters

Escolarização de alunos com altas habilidades/superdotação: um apoio virtual

According to current legislation, is part of the Target of Special Education, students with high abilities/giftedness (HA/G). However, it appears that there are few studies on efficiency and effectiveness of diverse pedagogical practice for students with these characteristics. With increasing globalization, are multiplied opportunities for transnational education programs and educational services, particularly through the Internet, increasing the need for information services and accreditation of institutions and educational programs. This study aims to: a) develop a website containing information on high abilities/giftedness; b) evaluate the design of teachers on applicability of the site; c) analyze the contributions posted on the site. Therefore, it was available to the participants of this research produced site. Consisted on the site, among other information, those relating to HA/G indicators. Was sent a questionnaire via the Internet, with nine closed questions and two open, to 2000 teachers, registered in the database Improvement Course in Educational Practices Inclusive conducted by UNESP, under the coordination of Prof. Dr. Vera Lucia Messias Fialho Capellini. Data were considering frequency responses. For the treatment we used the Google Docs. As result Program Observed how teachers are lacking this subject deserves further Top depth. Concerning the site he was Considered by the participants as a support tool to the teacher, Which helps to identify and recognition of Individuals with HA/G and contributes to information, training and practical pedagogical way. This, is expected to Contribute to the dissemination of this issue in society as well as the Possibility of Minimizing the myths about this population, since such myths exist due to the lack of information

How to progress from discourse to practice? a new agenda for change in medical schools into the next decade

In the context of medical school instruction, the segmented approach of a focus on specialties and excessive use of technology seem to hamper the development of the professional-patient relationship and an understanding of the ethics of this relationship. The real world presents complexities that require multiple approaches. Engagement in the community where health competence is developed allows extending the usefulness of what is learned. Health services are spaces where the relationship between theory and practice in health care are real and where the social role of the university can be revealed. Yet some competencies are still lacking and may require an explicit agenda to enact. Ten topics are presented for focus here: environmental awareness, involvement of students in medical school, social networks, interprofessional learning, new technologies for the management of care, virtual reality, working with errors, training in management for results, concept of leadership, and internationalization of schools. Potential barriers to this agenda are an underinvestment in ambulatory care infrastructure and community-based health care facilities, as well as in information technology offered at these facilities; an inflexible departmental culture; and an environment centered on a discipline-based medical curriculum.

Role of common mental and physical disorders in partial disability around the world

Background Mental and physical disorders are associated with total disability, but their effects on days with partial disability (i.e. the ability to perform some, but not full-role, functioning in daily life) are not well understood. Aims To estimate individual (i.e. the consequences for an individual with a disorder) and societal effects (i.e. the avoidable partial disability in the society due to disorders) of mental and physical disorders on days with partial disability around the world. Method Respondents from 26 nationally representative samples (n=61 259, age 18+) were interviewed regarding mental and physical disorders, and day-to-day functioning. The Composite International Diagnostic Interview, version 3.0 (CIDI 3.0) was used to assess mental disorders; partial disability (expressed in full day equivalents) was assessed with the World Health Organization Disability Assessment Schedule in the CIDI 3.0. Results Respondents with disorders reported about 1.58 additional disability days per month compared with respondents without disorders. At the individual level, mental disorders (especially post-traumatic stress disorder, depression and bipolar disorder) yielded a higher number of days with disability than physical disorders. At the societal level, the population attributable risk proportion due to physical and mental disorders was 49% and 15% respectively. Conclusions Mental and physical disorders have a considerable impact on partial disability, at both the individual and at the societal level. Physical disorders yielded higher effects on partial disability than mental disorders.

Reproductive biology and species geographical distribution in the Melastomataceae: a survey based on New World taxa

Apomictic plants are less dependent on pollinator services and able to occupy more diverse habitats than sexual species. However, such assumptions are based on temperate species, and comparable evaluation for species-rich Neotropical taxa is lacking. In this context, the Melastomataceae is a predominantly Neotropical angiosperm family with many apomictic species, which is common in the Campos Rupestres, endemism-rich vegetation on rocky outcrops in central Brazil. In this study, the breeding system of some Campo Rupestre Melastomataceae was evaluated, and breeding system studies for New World species were surveyed to test the hypothesis that apomixis is associated with wide distributions, whilst sexual species have more restricted areas. The breeding systems of 20 Campo Rupestre Melastomataceae were studied using hand pollinations and pollen-tube growth analysis. In addition, breeding system information was compiled for 124 New World species of Melastomataceae with either wide (1000 km) or restricted distributions. Most (80 ) of the Campo Rupestre species studied were self-compatible. Self-incompatibility in Microlicia viminalis was associated with pollen-tube arrest in the style, as described for other Melastomataceae, but most self-incompatible species analysed showed pollen-tube growth to the ovary irrespective of pollination treatment. Apomictic species showed lower pollen viability and were less frequent among the Campo Rupestre plants. Among the New World species compiled, 43 were apomictic and 77 sexual (24 self-incompatible and 53 self-compatible). Most apomictic (86 ) and self-incompatible species (71 ) presented wide distributions, whilst restricted distributions predominate only among the self-compatible ones (53 ). Self-compatibility and dependence on biotic pollination were characteristic of Campo Rupestre and narrowly distributed New World Melastomataceae species, whilst apomictics are widely distributed. This is, to a certain extent, similar to the geographical parthenogenesis pattern of temperate apomictics.

Groups of services delivered by Brazilian branchless banking and respective network integration models

Over the last decade, Brazil has pioneered an innovative model of branchless banking, known as correspondent banking, involving distribution partnership between banks, several kinds of retailers and a variety of other participants, which have allowed an unprecedented growth in bank outreach and became a reference worldwide. However, despite the extensive number of studies recently developed focusing on Brazilian branchless banking, there exists a clear research gap in the literature. It is still necessary to identify the different business configurations involving network integration through which the branchless banking channel can be structured, as well as the way they relate to the range of bank services delivered. Given this gap, our objective is to investigate the relationship between network integration models and services delivered through the branchless banking channel. Based on twenty interviews with managers involved with the correspondent banking business and data collected on almost 300 correspondent locations, our research is developed in two steps. First, we created a qualitative taxonomy through which we identified three classes of network integration models. Second, we performed a cluster analysis to explain the groups of financial services that fit each model. By contextualizing correspondents' network integration processes through the lens of transaction costs economics, our results suggest that the more suited to deliver social-oriented, "pro-poor'' services the channel is, the more it is controlled by banks. This research offers contributions to managers and policy makers interested in understanding better how different correspondent banking configurations are related with specific portfolios of services. Researchers interested in the subject of branchless banking can also benefit from the taxonomy presented and the transaction costs analysis of this kind of banking channel, which has been adopted in a number of developing countries all over the world now.

Mapping virtual networks onto substrate networks

Network virtualization is a promising technique for building the Internet of the future since it enables the low cost introduction of new features into network elements. An open issue in such virtualization is how to effect an efficient mapping of virtual network elements onto those of the existing physical network, also called the substrate network. Mapping is an NP-hard problem and existing solutions ignore various real network characteristics in order to solve the problem in a reasonable time frame. This paper introduces new algorithms to solve this problem based on 0–1 integer linear programming, algorithms based on a whole new set of network parameters not taken into account by previous proposals. Approximative algorithms proposed here allow the mapping of virtual networks on large network substrates. Simulation experiments give evidence of the efficiency of the proposed algorithms.
