Construção das capacidades organizacionais de tecnologia da informação no contexto dos sistemas institucionais integrados de gestão da UFRN

The IT capability is a organizational ability to perform activities of this role more effectively and an important mechanism in creating value. Its building process (stages of creation and development) occurs through management initiatives for improvement in the performance of their activities, using human resources and IT assets complementary responsible for the evolution of their organizational routines. This research deals with the IT capabilities related to SIG (integrated institutional management systems), built and deployed in UFRN (Universidade Federal do Rio Grande do Norte) to realization and control of administrative, academic and human resources activities. Since 2009, through cooperative agreements with federal and educational institutions of direct administration, UFRN has supported the implementation of these systems, currently involving more than 30 institutions. The present study aims to understand how IT capabilities, relevant in the design, implementation and dissemination of SIG, were built over time. This is a single case study of qualitative and longitudinal nature, performed by capturing, coding and analysis from secondary data and from semi-structured interviews conducted primarily with members of Superintenência de Informática, organizational unit responsible for SIG systems in UFRN. As a result, the technical, of internal relationship and external cooperation capabilities were identified as relevant in the successful trajectory of SIG systems, which have evolved in different ways. The technical capacity, initiated in 2004, toured the stages of creation and development until it reached the stage of stability in 2013, due to technological limits. Regarding the internal relationship capability, begun in 2006, it toured the stages of creation and development, having extended its scope of activities in 2009, being in development since then. Unlike the standard life cycle observed in the literature, the external cooperation capability was initiated by an intensity of initiatives and developments in the routines in 2009, which were decreasing to cease in 2013 in order to stabilize the technological infrastructure already created for cooperative institutions. It was still identified the start of cooperation in 2009 as an important event selection, responsible for changing or creating trajectories of evolution in all three capacities. The most frequent improvements initiatives were of organizational nature and the internal planning activity has been transformed over the routines of the three capabilities. Important resources and complementary assets have been identified as important for the realization of initiatives, such as human resources technical knowledge to the technical capabilities and external cooperation, and business knowledge, for all of them, as well as IT assets: the iproject application for control of development processes, and the document repository wiki. All these resources and complementary assets grew along the capacities, demonstrating its strategic value to SINFO/UFRN

Sistemas de gerenciamento de bibliotecas: riscos decorrentes do processo de migração de dados

This work aims to analyze risks related to information technology (IT) in procedures related to data migration. This is done considering ALEPH, Integrated Libray System (ILS) that migrated data to the Library Module present in the software called Sistema Integrado de Gestão de Atividades Acadêmicas (SIGAA) at the Zila Mamede Central Library at the Federal University of Rio Grande do Norte (UFRN) in Natal/Brazil. The methodological procedure used was of a qualitative exploratory research with the realization of case study at the referred library in order to better understand this phenomenon. Data collection was able once there was use of a semi-structured interview that was applied with (11) subjects that are employed at the library as well as in the Technology Superintendence at UFRN. In order to examine data Content analysis as well as thematic review process was performed. After data migration the results of the interview were then linked to both analysis units and their system register with category correspondence. The main risks detected were: data destruction; data loss; data bank communication failure; user response delay; data inconsistency and duplicity. These elements point out implication and generate disorders that affect external and internal system users and lead to stress, work duplicity and hassles. Thus, some measures were taken related to risk management such as adequate planning, central management support, and pilot test simulations. For the advantages it has reduced of: risk, occurrence of problems and possible unforeseen costs, and allows achieving organizational objectives, among other. It is inferred therefore that the risks present in data bank conversion in libraries exist and some are predictable, however, it is seen that librarians do not know or ignore and are not very worried in the identification risks in data bank conversion, their acknowledge would minimize or even extinguish them. Another important aspect to consider is the existence of few empirical research that deal specifically with this subject and thus presenting the new of new approaches in order to promote better understanding of the matter in the corporate environment of the information units

O Contributo dos Sistemas de Informação para a Eficácia da Liderança e para a Mudança do Comportamento Organizacional

O presente trabalho debruça-se sobre os constructos da liderança e do comportamento de auto-eficácia da liderança nas organizações. Reflecte-se sobre a importância dos sistemas de informação no clima organizacional, com efeitos sobre a eficácia na liderança. Trata-se de uma perspetiva pertinente na conjuntura organizacional atual, dado que incide sobre valores patrimoniais intangíveis que, quando dinamizados, dão suporte à performance organizacional. A nossa preocupação central é a auto-eficácia. Através dela pretende-se melhorar a eficiência organizacional, porque minimiza prejuízos e desperdícios. Também se relaciona a eficácia com o desempenho da liderança organizacional e com o capital ‘confiança’. Dessa forma, os novos caminhos passam por auscultar a percepção dos colaboradores sobre a importância da cultura organizacional face ao desempenho e à eficácia de longo prazo na organização. Com a presente reflexão, evidencia-se que a espiritualidade no local de trabalho é um factor de apoio ao desenvolvimento holístico dos colaboradores. Fica sublinhado que é fundamental que os líderes tenham noção e consciência de “si” e dos seus papéis, e como estes se reflectem no seu comportamento quotidiano na organização. O estudo assenta num trabalho de campo, elaborado numa organização intensiva em informação e que presta serviços de consultoria e informática. Os resultados apurados tentam dizer que, globalmente, no estudo longitudinal das hetero-percepções dos gestores directos e indirectos, o gap cultural diminuiu em todas as dimensões relativas às competências dos papéis, sendo vital destacar o quadrante designado por Apoio. As hetero-percepções dos gestores directos demonstram que o menor gap cultural mantem-se no quadrante de Objectivos Racionais e Competir no modelo de CVF, caracterizado por uma cultura de mercado, e relacionado com a fase da Combinação no modelo de SECI (processos que fomentam os relacionamentos e intercâmbios informais – conversão do conhecimento explícito para o explícito). Enquanto que o maior gap cultural reside no quadrante Apoio e Colaborar no modelo CVF, relacionado com a fase da Socialização no modelo de SECI (processos que fomentam os relacionamentos e intercâmbios informais – conhecimento tácito para tácito). Como o gap cultural diminuiu em todas as dimensões, pode realçar uma melhoria das percepções do desempenho organizacional. Contudo, um resultado inesperado está associado ao quadrante Apoio com a cultura de clã, uma vez que são os gestores indirectos na empresa em estudo que fomentam esta cultura, e não os gestores directos, conforme seria desejável. Um resultado favorável para o estudo da auto-eficácia da liderança demonstra que as médias são mais elevadas para atributos de Gestão e Resolução de Problemas. Os resultados que não corresponderam às expectativas iniciais estão associados às médias baixas relativamente aos atributos Sociais/de Comunicação, o que pode ser uma debilidade porque seria desejável que a equipa de gestão tivesse maior sensibilidade perante os capitais sociais, emocionais e espirituais, os quais estão relacionados com estes atributos.

Outsourcing en servicios de tecnología informática

Históricamente las organizaciones han venido soportando totalmente la infraestructura de tecnología, pero actualmente ha surgido la herramienta gerencial de subcontratar (en inglés Outsourcing) la gestión tecnológica que no sea parte integral del negocio. Pero el problema de esta situación radica en que las organizaciones han llevado a sus departamentos de sistemas a utilizar esta herramienta desde criterios muy subjetivos y no sobre políticas y procedimientos claros. A su vez, el mercado en nuestro medio está en una etapa de florecimiento y no existen metodologías que permitan a las organizaciones establecer con nitidez conceptual la conveniencia del uso del Outsourcing.

Estudo empírico de antecedentes do sucesso de sistemas de informação: análise de um sistema de apoio à decisão em uma universidade pública

Universities are institutions that generate and manipulate large amounts of data as a result of the multiple functions they perform, of the amount of involved professionals and students they attend. Information gathered from these data is used, for example, for operational activities and to support decision-making by managers. To assist managers in accomplishing their tasks, the Information Systems (IS) are presented as tools that offer features aiming to improve the performance of its users, assist with routine tasks and provide support to decision-making. The purpose of this research is to evaluate the influence of the users features and of the task in the success of IS. The study is of a descriptive-exploratory nature, therefore, the constructs used to define the conceptual model of the research are known and previously validated. However, individual features of users and of the task are IS success antecedents. In order to test the influence of these antecedents, it was developed a decision support IS that uses the Multicriteria Decision Aid Constructivist (MCDA-C) methodology with the participation and involvement of users. The sample consisted of managers and former managers of UTFPR Campus Pato Branco who work or have worked in teaching activities, research, extension and management. For data collection an experiment was conducted in the computer lab of the Campus Pato Branco in order to verify the hypotheses of the research. The experiment consisted of performing a distribution task of teaching positions between the academic departments using the IS developed. The task involved decision-making related to management activities. The data that fed the system used were real, from the Campus itself. A questionnaire was answered by the participants of the experiment in order to obtain data to verify the research hypotheses. The results obtained from the data analysis partially confirmed the influence of the individual features in IS success and fully confirmed the influence of task features. The data collected failed to support significant ratio between the individual features and the individual impact. For many of the participants the first contact with the IS was during the experiment, which indicates the lack of experience with the system. Regarding the success of IS, the data revealed that there is no significance in the relationship between Information Quality (IQ) and Individual Impact (II). It is noteworthy that the IS used in the experiment is to support decision-making and the information provided by this system are strictly quantitative, which may have caused some conflict in the analysis of the criteria involved in the decision-making process. This is because the criteria of teaching, research, extension and management are interconnected such that one reflects on another. Thus, the opinion of the managers does not depend exclusively on quantitative data, but also of knowledge and value judgment that each manager has about the problem to be solved.

Modelo para gestionar el conocimiento en el sector textil de Medellín, empleando dinámica de sistemas

Este artículo evalúa la relación de causalidad entre la gestión del conocimiento y las capacidades de innovación tecnológica, y el efecto de esta relación sobre los resultados operacionales del sector textil en la ciudad de Medellín. Se empleó la metodología de dinámica de sistemas, con simulación de esce­narios para valorar las condiciones actuales de las organizaciones del sector en términos de acumulación de conocimiento y capacidades. La información se obtuvo mediante entrevistas a expertos y acceso a información especializada del sector. Se evidencia que una mejora de la relación entre la gestión del conocimiento e innovación tecnológica genera un incremento aproximado del 15% en los ingresos operacionales del sector. Asimismo, se encontró que a medida que las variables comunes de interés (Es­trategias organizacionales, canales de comunicación, formación, cultura, acciones de fortalecimiento en I+D), se acercan a los valores deseados, la acumulación de conocimiento y de capacidades de innovación tecnológica alcanzan los valores objetivos.

Analizar y comparar el lenguaje de alto nivel SystemC frente a los de HDL. aplicación al diseño de sistemas de computo

La complejidad de los sistemas actuales de computación ha obligado a los diseñadores de herramientas CAD/CAE a acondicionar lenguajes de alto nivel, tipo C++, para la descripción y automatización de estructuras algorítmicas a sus correspondientes diseños a nivel físico. Los proyectos a realizar se encuadran dentro de una línea de trabajo consistente en estudiar la programación, funcionamiento de los lenguajes SystemC y SystemVerilog, sus herramientas asociadas y analizar cómo se adecuan a las restricciones temporales y físicas de los componentes (librerías, IP's, macro-celdas, etc) para su directa implementación. En una primera fase, y para este TFG, se estudiarán los componentes que conforman el framework elegido que es SystemC y su inclusión en herramientas de diseño arquitectural. Este conocimiento nos ayudará a entender el funcionamiento y capacidad de dicha herramienta y proceder a su correcto manejo. Analizaremos y estudiaremos unos de los lenguajes de alto nivel de los que hace uso dicha herramienta. Una vez entendido el contexto de aplicación, sus restricciones y sus elementos, diseñaremos una estructura hardware. Una vez que se tenga el diseño, se procederá a su implementación haciendo uso, si es necesario, de simuladores. El proyecto finalizará con una definición de un conjunto de pruebas con el fin de verificar y validar la usabilidad y viabilidad de nuestra estructura hardware propuesta.

Diseño de sistemas digitales

Hoy en día estamos inundados de cientos de sistemas digitales que juegan un papel discreto pero agradecido en muchas de nuestras actividades diarias. No hace muchos años, no sabíamos lo que era un mando a distancia y, hoy en día, no sabemos vivir sin él. Muchos productos de consumo basados en sistemas digitales son ya artículos de casi primera necesidad. La revolución digital, basada en Ia microelectrónica, Ia informática y las telecomunicaciones, comenzó en los años setenta con Ia aparición del microprocesador. En los 80, los microprocesadores facilitaron Ia llegada de los ordenadores personales (PC, Personal Computer) en un momento en el que nadie podía sospechar el éxito que alcanzarían. En los 90, triunfó el PC multimedia y su conexión a red junto con el auge de Ia telefonía móvil de segunda generación. La llegada del siglo XXI ha consolidado Internet y ha puesto las bases para el despliegue de Ia tercera generación de móviles. Los siguientes pasos apuntan entornos inteligentes donde terminales multimedia inalámbricos se comunicarán de forma espontánea con dispositivos próximos y podrán acceder a cualquier red de comunicaciones. Este manual pretende repasar esta revolución estudiando, desde un punto de vista hardware, los sistemas digitales basados en microprocesadores de última generación.

Desarrollo de técnicas de aprendizaje automático para la predicción de resultados de partidos en ligas futbolísiticas

En la actualidad, existen un gran número de investigaciones que usan técnicas de aprendizaje automático basadas en árboles de decisión. Como evolución de dichos trabajos, se han desarrollado métodos que usan Multiclasificadores (Random forest, Boosting, Bagging) que resuelven los mismos problemas abordados con árboles de decisión simples, aumentando el porcentaje de acierto. El ámbito de los problemas resueltos tradicionalmente por dichas técnicas es muy variado aunque destaca la bio-informática. En cualquier caso, la clasificación siempre puede ser consultada a un experto considerándose su respuesta como correcta. Existen problemas donde un experto en la materia no siempre acierta. Un ejemplo, pueden ser las quinielas (1X2). Donde podemos observar que un conocimiento del dominio del problema aumenta el porcentaje de aciertos, sin embargo, predecir un resultado erróneo es muy posible. El motivo es que el número de factores que influyen en un resultado es tan grande que, en muchas ocasiones, convierten la predicción en un acto de azar. En este trabajo pretendemos encontrar un multiclasificador basado en los clasificadores simples más estudiados como pueden ser el Perceptrón Multicapa o Árboles de Decisión con el porcentaje de aciertos más alto posible. Con tal fin, se van a estudiar e implementar una serie de configuraciones de clasificadores propios junto a multiclasificadores desarrollados por terceros. Otra línea de estudio son los propios datos, es decir, el conjunto de entrenamiento. Mediante un estudio del dominio del problema añadiremos nuevos atributos que enriquecen la información que disponemos de cada resultado intentando imitar el conocimiento en el que se basa un experto. Los desarrollos descritos se han realizado en R. Además, se ha realizado una aplicación que permite entrenar un multiclasificador (bien de los propios o bien de los desarrollados por terceros) y como resultado obtenemos la matriz de confusión junto al porcentaje de aciertos. En cuanto a resultados, obtenemos porcentajes de aciertos entre el 50% y el 55%. Por encima del azar y próximos a los resultados de los expertos.
