O papel da gramática numa proposta pedagógica baseada em gêneros discursivos

In the last decade, pedagogical proposals for language teaching that aimed at developing the students’ literacy have raised an important question regarding the elaboration of language teaching plans concerning the role of grammar. How should we treat the relationship grammar-text in this new perspective? The aim of this paper is to propose a way of integrating text and grammar in an English course plan for Information Technology (IT) students which gives priority to the reading ability. We have based our proposal on concepts from English for Specific Purpose (ESP) by focusing on reading and also on literacy and text gender studies.

Innovation in the field of Information Technology (IT) have made companies evaluate their processes and activity of its supply chain to conform to this new reality. In the supply chain management, one of the tools that revolutionized the activities was the use of management information systems such as ERP tool. This system allows greater integration of data from multiple areas of the enterprise and beyond, giving more activities to processes and activities. This work aims to analyze the results and impacts of the restructuring of an equipment leasing process in a Brazilian media company and verify that the gains and improvements that were targeted in the initial design of this restructuring have been achieved. Also the risks identified with this change will be studied, the reactions of those involved in this process and the performance of the chain as a whole. To carry out this work was carried out a single case study with data collection in the assessed company and literature related to supply chain and information systems

Robust isothermal electric control of exchange bias at room temperature

Voltage-controlled spin electronics is crucial for continued progress in information technology. It aims at reduced power consumption, increased integration density and enhanced functionality where non-volatile memory is combined with highspeed logical processing. Promising spintronic device concepts use the electric control of interface and surface magnetization. From the combination of magnetometry, spin-polarized photoemission spectroscopy, symmetry arguments and first-principles calculations, we show that the (0001) surface of magnetoelectric Cr2O3 has a roughness-insensitive, electrically switchable magnetization. Using a ferromagnetic Pd/Co multilayer deposited on the (0001) surface of a Cr2O3 single crystal, we achieve reversible, room-temperature isothermal switching of the exchange-bias field between positive and negative values by reversing the electric field while maintaining a permanent magnetic field. This effect reflects the switching of the bulk antiferromagnetic domain state and the interface magnetization coupled to it. The switchable exchange bias sets in exactly at the bulk Néel temperature.

Tecnologie ad agenti e sistemi embedded

Information technology (IT) is on the verge of another revolution. Driven by the increasing capabilities and ever declining costs of computing and communications devices, IT is being embedded into a growing range of physical devices linked together through networks and will become ever more pervasive as the component technologies become smaller, faster, and cheaper. [..] These networked systems of embedded computers, referred to as EmNets throughout this report, have the potential to change radically the way people interact with their environment by linking together a range of devices and sensors that will allow information to be collected, shared, and processed in unprecedented ways.[..] The use of EmNets throughout society could well dwarf previous milestones in the information revolution.[..] IT will eventually become \textbf{an invisible component of almost everything} in everyone`s surroundings. Con il ridursi dei costi e l'aumentare della capacità di computazione dei componenti elettronici sono proliferate piattaforme che permettono al bambino come all'ingegnere di sviluppare un'idea che trasversalmente taglia il mondo reale e quello virtuale. Una collisione tra due mondi che fino a poco tempo fa era consentita esclusivamente a professionisti. Oggetti che possono acquisire o estendere funzionalità, che ci permettono di estendere la nostra percezione del mondo e di rivalutarne i suoi limiti. Oggetti connessi alla 'rete delle reti' che condividono ed elaborano dati per un nuovo utilizzo delle informazioni. Con questa tesi si vuole andare ad esplorare l'applicazione degli agenti software alle nuove piattaforme dei sistemi embedded e dell'Internet of Things, tecnologie abbastanza mature eppure non ancora esplorate a fondo. Ha senso modellare un sistema embedded con gli agenti?

Promotion of health in older people: a randomised controlled trial of health risk appraisal in British general practice

BACKGROUND: there is inadequate evidence to support currently formulated NHS strategies to achieve health promotion and preventative care in older people through broad-based screening and assessment in primary care. The most extensively evaluated delivery instrument for this purpose is Health Risk Appraisal (HRA). This article describes a trial using HRA to evaluate the effect on health behaviour and preventative-care uptake in older people in NHS primary care. METHODS: a randomised controlled trial was undertaken in three London primary care group practices. Functionally independent community-dwelling patients older than 65 years (n = 2,503) received a self-administered Health Risk Appraisal for Older Persons (HRA-O) questionnaire leading to computer-generated individualised written feedback to participants and general practitioners (GPs), integrated into practice information-technology (IT) systems. All primary care staff received training in preventative health in older people. The main outcome measures were self-reported health behaviour and preventative care uptake at 1-year follow-up. RESULTS: of 2,503 individuals randomised, 2,006 respondents (80.1%) (intervention, n = 940, control n = 1,066) were available for analysis. Intervention group respondents reported slightly higher pneumococcal vaccination uptake and equivocal improvement in physical activity levels compared with controls. No significant differences were observed for any other categories of health behaviour or preventative care measures at 1-year follow-up. CONCLUSIONS: HRA-O implemented in this way resulted in minimal improvement of health behaviour or uptake of preventative care measures in older people. Supplementary reinforcement involving contact by health professionals with patients over and above routine clinical encounters may be a prerequisite to the effectiveness of IT-based delivery systems for health promotion in older people.

Fostering sustainable urban development in Nakuru, Kenya Rift Valley

The town of Nakuru—Kenya's fourth largest town—lies in a unique setting in the Great Rift Valley. Recent developments on the Menengai Crater, the Mau Escarpment, and the Bahati Highlands exemplify the impacts of poorly planned urban growth on mountain ecosystems. The Nakuru Local Urban Observatory (LUO) project was initiated by the Municipal Council of Nakuru in January 2003, in collaboration with the Centre for Development and Environment (CDE) of the University of Berne and the Intermediate Technology Development Group (ITDG), and with funding from the Swiss Agency for Development and Cooperation (SDC). The project aims to provide a framework for sustainable urban development practices by building technical skills and improving participation by local stakeholders in decision-making processes. The potentials of information technology (IT) are being tapped to provide up-to-date information to decision-makers and democratize access to information, in order to improve public participation. The overall objective is to find ways of achieving better urban management in order to mitigate non-sustainable development trends in the town and its surroundings.

PubDNA Finder in a Nutshell. Searching the Life Sciences Literature with Sequences of Nucleic Acids

Biomedical researchers and clinicians working with molecular technologies in routine clinical practice often need to review the available literature to gather information regarding specific sequences of nucleic acids. This includes, for instance, finding articles related to a concrete DNA sequence, or identifying empirically-validated primer/probe sequences to evaluate the presence of different micro-organisms. Unfortunately, these hard and time-consuming tasks often need to be manually performed by researchers themselves since no publicly available biomedical literature search engine, e.g. PubMed, PubMed Central (PMC), etc., provides the required search functionalities. In this article, we describe PubDNA Finder, a web service that enables users to perform advanced searches on PubMed Central-indexed full text articles with sequences of nucleic acids

Estudio del impacto del usuario final en los procesos de desarrollo de sistemas de información

Durante décadas y aun en la actualidad muchas organizaciones, a nivel mundial, continúan afrontando pérdidas significativas debido a fracasos parciales y totales respecto a sus inversiones en sistemas de información (SI), planteando serios retos a los niveles gerenciales y los profesionales de SI. Estadísticas alarmantes y décadas de experiencia en la praxis en el área de SI en diversas organizaciones llevan al autor a poner el énfasis en los usuarios finales internos (UF) que son designados como representantes (UFR) de sus pares en los proyectos de desarrollo de SI (PDSI) por considerarlos como factores influyentes de manera significativa en el problema. Particularmente, con enfoque en ciertos factores de los UFR críticos para el éxito de los PDSI, con dimensiones analizadas de forma aislada o incompleta en otros estudios empíricos, a la fecha. No se encontraron estudios en Latinoamérica ni en otras latitudes que abordasen el fenómeno del éxito/fracaso de los SI desde el punto de vista adoptado en esta tesis. Por ello, esta investigación empírica ha evaluado en qué grado estos factores pudiesen influenciar los resultados durante el desarrollo e implementación de SI y su posible impacto en la satisfacción de los UF, siendo esta última aceptada por variados autores como la principal medida del éxito de los SI. Este estudio fue realizado en América Latina en las cuatro grandes empresas industriales que integran verticalmente el sector aluminio de Venezuela, sometidas a un macro PDSI para instalar el paquete, de tipo ERP, SAP/R3. Experimentados profesionales fueron encuestados o entrevistados, tales como altos ejecutivos, desarrolladores, líderes de proyecto y líderes de los UF. Un enfoque metodológico de triangulación permitió combinar un análisis cuantitativo con un análisis cualitativo interpretativo del tipo hermenéutico/dialéctico, hallándose resultados convergentes y complementarios. Un análisis estadístico, utilizando Partial Least Squares (PLS), seguido de un análisis hermenéutico/dialéctico. Los resultados confirmaron un hecho importante: en los casos problemáticos, paradójicamente, los orígenes de las razones de rechazo de esos SI argumentadas por los UF, en alto grado, apuntaron a los UFR o a ellos mismos. Los resultados también confirmaron la prevalencia de factores de orden cognitivo, conductual y político en estas organizaciones sobre los tecnológicos, al igual que el alto riesgo de dar por sentado la presencia y calidad de los factores requeridos de los UFR y de los otros factores estudiados. La validación estadística del modelo propuesto reveló al constructo conocimientos de los UFR como la principal variable latente, con los variables indicadoras que componen este constructo ejerciendo la mayor influencia sobre la calidad y el éxito de los SI. Un hallazgo contrario al de otros estudios, mostró que los conocimientos sobre las tecnologías de la información (TI) fueron los menos relevantes. Los SI de nómina y de administración de los RRHH fueron los más problemáticos, como suele ser el caso, por su complejidad en organizaciones grandes. Las conclusiones principales confirman el decisivo rol de los UF para el éxito de los PDSI y su relación con la creciente problemática planteada, la cual amerita más investigación y de las organizaciones una mayor atención y preparación. Descuidar los factores humanos y sociales así como una efectiva planificación y gestión de los mismos en preparación para estos proyectos origina serios riesgos. No obstante las limitaciones de este trabajo, la problemática analizada suele influir en los PDSI en diversas organizaciones, indistintamente de su tamaño o tipo de SI, estimándose, por tanto, que los resultados, conclusiones y recomendaciones de esta investigación tienen un alto grado de generalización. Una relación de indicadores claves es suministrada con fines preventivos. Finalmente, los factores evaluados pueden usarse para ampliar el modelo reconocido de DeLone y McLean (2003), conectándolos como variables latentes de sus variables independientes calidad de la información y calidad del SI. ABSTRACT For decades, many organizations worldwide have been enduring heavy losses due to partial and total failures regarding their investments in information systems (IS), posing serious challenges to all management levels and IS practitioners. Alarming statistics in this regard and decades of practice in the IS area lead the author to place an emphasis on the end users (EU) who are appointed in representation of their peers (EUR) to IS development projects (ISDP), considering them as highly influential factors on the problem. Especially, focusing on certain EUR success factors, and their dimensions, deemed critical to any IS development and implementation, omitted or not thoroughly analyzed neither in the theory nor in the empirical research on the subject, so far. No studies were found in Latin America or elsewhere addressing the phenomenon of IS success/failure from the perspective presented herein. Hence, this empirical research has assessed to what degree such factors can influence the outcomes of an ISDP and their feasible impact on the EU´s satisfaction, being the latter accepted by several authors as the main measure of IS success. This study was performed in Latin America embracing four major industrial enterprises, which vertically integrate the aluminum sector of Venezuela, subjected to a macro ISDP to install the ERP-type package SAP/R3. The field work included surveying and interviewing experienced professionals such as IS executives, IS developers, IS project leaders and end-user project leaders. A triangulation methodological approach allowed combining quantitative and interpretive analyses, obtaining convergent and complementing results. A statistical analysis, using Partial Least Squares (PLS), was carried out followed by a hermeneutical/dialectical analysis. Results confirmed a major finding: in problematic cases, paradoxically, the origins of IS rejection reasons argued by the EU, at a high degree, were usually traceable to the EUR and themselves. The results also confirmed the prevalence of cognitive, behavioral and political factors in these organizations as well as the high risk of taking for granted the presence and quality of those factors demanded from the EUR. The statistical validation of the proposed model revealed the construct EUR knowledge as the main latent variable, with its items exerting a major influence on IS quality and success. Another finding, in contradiction with that of other studies, proved knowledge of information technology (IT) aspects to be irrelevant. The payroll and the human resources administration IS were the most problematic, as is usually the case in large companies. The main conclusions confirm the EU´s decisive role for IS success and their relationship with the problem, which continues, demanding more research and, from organizations, more attention and preparation. Neglecting human and social factors in organizations as well as their effective planning and management in preparation for ISDP poses serious risks. Despite the limitations of this work, the analyzed problem tends to influence ISDP in a wide range of organizations; regardless of their size or type of IS, thus showing a high degree of generalization. Therefore it is believed that the results, conclusions and suggestions of this research have a high degree of generalization. A detailed checklist comprising key measures is provided for preventive actions. Finally, the factors evaluated can be used to expand the well-known model of DeLone & McLean (2003), by connecting them as latent variables of its independent variables information quality and IS quality.
