Las tecnologías de la Información y las Comunicaciones (TIC de ahora en adelante) son centrales para la creación de una economía global centrada en el conocimiento. Las TIC pueden jugar un importante papel acelerando el crecimiento de una economía, erradicando la pobreza y promoviendo un desarrollo sostenible en países en desarrollo y economías en transición facilitando así una beneficiosa integración a la economía global. En el reporte del Milenio, el primer secretario general de las Naciones Unidas, Kofi Annan, presenta un énfasis en la importancia que para los países en desarrollo la revolución digital conlleva. A su vez, se señala la significativa función que el gobierno y entidades educativas, entre otras instituciones, están desarrollando para construir el puente digital que divide los países desarrollados de los en desarrollo. Una de las iniciativas mas importantes que se desarrollan a nivel mundial se ha denominado; UNITeS, (The United Nations Information Technology Service). Esta iniciativa propuesta por el Secretario General de la ONU, anunciada en su Informe del Milenio, estimula y facilita las contribuciones de los voluntarios para cerrar la brecha digital. Este marco de colaboración brinda la oportunidad a voluntarios para que compartan sus conocimientos y aumenten así la capacidad de personas de países en desarrollo para la utilización de las TIC en Pro del desarrollo humano. Las tecnologías de la Información no son una formula mágica que va a solucionar todos nuestros problemas; pero, es una poderosa fuerza que puede y debe ser explotada para alcanzar nuestra misión global en términos de un desarrollo sostenible. Esta misión relaciona elementos tanto éticos como económicos. La nueva economía en el largo plazo puede solo ser productiva y sostenible si se extiende al alcance de todos y responde a las necesidades y demandas de todas las comunidades. Es así como la Universidad del Rosario reconoce esta única oportunidad para ser actora de cambio y afianzar su posición como una Universidad de docencia que hace investigación.

Las tecnologías de la información han empezado a ser un factor importante a tener en cuenta en cada uno de los procesos que se llevan a cabo en la cadena de suministro. Su implementación y correcto uso otorgan a las empresas ventajas que favorecen el desempeño operacional a lo largo de la cadena. El desarrollo y aplicación de software han contribuido a la integración de los diferentes miembros de la cadena, de tal forma que desde los proveedores hasta el cliente final, perciben beneficios en las variables de desempeño operacional y nivel de satisfacción respectivamente. Por otra parte es importante considerar que su implementación no siempre presenta resultados positivos, por el contrario dicho proceso de implementación puede verse afectado seriamente por barreras que impiden maximizar los beneficios que otorgan las TIC.

Este trabajo de grado aborda la contribución del periodismo en la configuración del debate en Colombia sobre política de drogas, a través de un análisis de contenido a las columnas y editoriales publicadas entre 2009 y 2013 en cuatro medios de referencia del país. Se identificaron los perfiles de quienes participaron, los argumentos y las políticas defendidas que plantearon, y la manera como presentaron sus opiniones en El Espectador, El Tiempo, La Silla Vacía y Semana. El desarrollo de la discusión en los textos demuestra una evolución respecto al tema en la medida que hay una transformación del paradigma punitivo hacia un camino menos restrictivo frente a la producción, el tráfico y consumo de drogas ilícitas. Se sugiere que los hechos coyunturales motivaron en parte dicho cambio al ejercer influencia en los giros y la visibilidad que toma el debate dentro de la prensa.

El presente estudio de caso analiza y compara la manera en que los editoriales El Tiempo y El Colombiano reflejaron la personalización de la figura presidencial durante el primer gobierno de Álvaro Uribe (2002-2004). El fenómeno de la personalización en política ha motivado a diferentes estudios y análisis, observándose la personalización como un fenómeno de largo alcance y de gran repercusión. En este sentido la personalización de la figura presidencial de Álvaro Uribe Vélez, es un factor predominante en el periodo 2002- 2004, enmarcado bajo la gobernabilidad mediática; evidenciado en la manera como las editoriales El Tiempo y El Colombiano mostraban al hombre que gobernaba a Colombia, provocando una centralización de la figura presidencial y no de la gestión de gobierno logrando encubrir los episodios de corrupción y clientelismo. Evidenciándose un traspaso de la política de ideas a una política de personas.

This study examines ICT adoption among 3,759 Colombian manufacturing firms, and attempts to identify the factors that are conducive to the adoption and usage of ICT at the firm level. Our major findings are (i) that the adoption of a given information and communication technology is better facilitated when a firm is relatively large, has large human capital, engages in more innovative activities, and when a firm’s organizational structure is better aligned with the given technology; (ii) that positive associations between the key determinants and ICT adoptions are more pronounced for small and medium-sized firms than for large ones, and (iii) that information spillovers within industries is also a determinant of ICT adoptions by the firms.

A gestão pedagógica do ensino e aprendizagem on-line: especificidades abordam os desafios da Gestão do Projeto Pedagógico que tem as Tecnologias de Informação e Comunicação por base didático-pedagógica. O fenômeno constitui-se na gestão do ensino-aprendizagem de curso lato senso a distância, no uso do computador conectado à internet, e a formação do educador especialista responsável pela coordenação, ensino, avaliação e/ou monitoria a frente do trabalho educativo. Reflete sobre os desafios da práxis pedagógica, subsidiada pela busca questionadora das tecnologias, a fim de responder também à demanda por inclusão sócio-digital. A abordagem metodológica de natureza qualitativa pauta-se na interpretação da realidade, de caráter hermenêutico com o intuito de considerar a experiência vivida pelos sujeitos na educação on-line a partir de uma visão crítica. Questiona o descompasso da educação formal brasileira e os avanços sociais com as incorporações de novas tecnologias de aprendizagens. Estabelece nas análises, a relação entre as teorias que sedimentam os objetivos do curso, as práticas de gestão e as influências ideológicas que marcam esse cenário, no PIGEAD da Universidade Federal Fluminense, Rio de Janeiro Brasil, período de 2010 a 2012. Os resultados desta pesquisa mostram que a interatividade, diferencial que aproxima o indivíduo e o torna parte da comunicação estabelecida na EAD on-line, não ocorre plenamente entre os sujeitos do processo. Além disso, a gestão democrática participativa declarada em seus objetivos de formação se mostra na realidade como prática centralizadora, sinalizando um descompasso entre teoria e prática. Esta pesquisa, entre outros, oferece elementos de avaliação e aprimoramento ao PIGEAD.

Construction materials and equipment are essential building blocks of every construction project and may account for 50-60 per cent of the total cost of construction. The rate of their utilization, on the other hand, is the element that most directly relates to a project progress. A growing concern in the industry that inadequate efficiency hinders its success could thus be accommodated by turning construction into a logistic process. Although mostly limited, recent attempts and studies show that Radio Frequency IDentification (RFID) applications have significant potentials in construction. However, the aim of this research is to show that the technology itself should not only be used for automation and tracking to overcome the supply chain complexity but also as a tool to generate, record and exchange process-related knowledge among the supply chain stakeholders. This would enable all involved parties to identify and understand consequences of any forthcoming difficulties and react accordingly before they cause major disruptions in the construction process. In order to achieve this aim the study focuses on a number of methods. First of all it develops a generic understanding of how RFID technology has been used in logistic processes in industrial supply chain management. Secondly, it investigates recent applications of RFID as an information and communication technology support facility in construction logistics for the management of construction supply chain. Based on these the study develops an improved concept of a construction logistics architecture that explicitly relies on integrating RFID with the Global Positioning System (GPS). The developed conceptual model architecture shows that categorisation provided through RFID and traceability as a result of RFID/GPS integration could be used as a tool to identify, record and share potential problems and thus vastly improve knowledge management processes within the entire supply chain. The findings thus clearly show a need for future research in this area.

Nowadays the use of information and communication technology is becoming prevalent in many aspects of healthcare services from patient registration, to consultation, treatment and pathology tests request. Manual interface techniques have dominated data-capture activities in primary care and secondary care settings for decades. Despites the improvements made in IT, usability issues still remain over the use of I/O devices like the computer keyboard, touch-sensitive screens, light pen and barcodes. Furthermore, clinicians have to use several computer applications when providing healthcare services to patients. One of the problems faced by medical professionals is the lack of data integrity between the different software applications which in turn can hinder the provision of healthcare services tailored to the needs of the patients. The use of digital pen and paper technology integrated with legacy medical systems hold the promise of improving healthcare quality. This paper discusses the issue of data integrity in e-health systems and proposes the modelling of "Smart Forms" via semiotics to potentially improve integrity between legacy systems, making the work of medical professionals easier and improve the quality of care in primary care practices and hospitals.

Procurement is one of major business operations in public service sector. The advance of information and communication technology (ICT) pushes this business operation to increase its efficiency and foster collaborations between the organization and its suppliers. This leads to a shift from the traditional procurement transactions to an e-procurement paradigm. Such change impacts on business process, information management and decision making. E-procurement involves various stakeholders who engage in activities based on different social and cultural practices. Therefore, a design of e-procurement system may involve complex situations analysis. This paper describes an approach of using the problem articulation method to support such analysis. This approach is applied to a case study from UAE.

Inducing rules from very large datasets is one of the most challenging areas in data mining. Several approaches exist to scaling up classification rule induction to large datasets, namely data reduction and the parallelisation of classification rule induction algorithms. In the area of parallelisation of classification rule induction algorithms most of the work has been concentrated on the Top Down Induction of Decision Trees (TDIDT), also known as the ‘divide and conquer’ approach. However powerful alternative algorithms exist that induce modular rules. Most of these alternative algorithms follow the ‘separate and conquer’ approach of inducing rules, but very little work has been done to make the ‘separate and conquer’ approach scale better on large training data. This paper examines the potential of the recently developed blackboard based J-PMCRI methodology for parallelising modular classification rule induction algorithms that follow the ‘separate and conquer’ approach. A concrete implementation of the methodology is evaluated empirically on very large datasets.

This paper raises methodological issues about the challenges and dilemmas of inclusive research practices reflecting on the work of an advisory group carrying out research on using Information and Communication Technology (ICT) to enhance community participation. The interests of three parties can be identified – the commissioning agent, the researchers and the researched – and these interplayed throughout the course of the research determining the outcomes. Given the relationship between inclusive research and advocacy, there were particular gains in enabling the voice of the advisory group to shape the way in which the research was conducted and to disseminate the findings both within the organisation and beyond. However, the fragility of these new structures required organisational changes for the research to be truly empowering. The experience of the group suggests the need for their involvement at all stages of the research process

Vid en tillbakablick på de senaste 25 års spelfilmer kan man se hur ett växande klimathot funnits med som en berättelseingrediens i ett antal spelfilmer från Hollywood mainstreamfåra. (Axelson 2008). År 2004 kom katastroffilmen The Day after Tomorrow som gjordes till objekt för en brittisk publikstudie. I denna studie analyserar forskargruppen hur The Day After Tomorrow påverkade publikens tankar kring klimatförändringar (Lowe et al. 2006). Den irländske forskaren Pat Brereton har initierat ett projekt inom HERA (Humanities in the European Research Area) med ett forskningsfokus på hur medier och film bidragit till ett ekologiskt paradigm som enligt Brereton, långsamt växer sig allt starkare hos den europeiska allmänheten (Brereton 2008). I mitt paper vill jag diskutera Breretons hypotes om ett ökande ekologiskt sentiment under framväxt hos en europeisk allmänhet över tid och hur denna hypotes bör underkastas en kritisk diskussion utifrån ett receptionsperspektiv. Vad säger existerande publikorienterad receptionsforskning om på vilket sätt klimatförändringar gestaltade på film kan ha förmågan att beröra processer relaterade till människors teoretiska övertygelser om tillvaron, grundläggande värderingar samt en livsåskådningsmässig grundhållning (Lowe et al. 2006, Axelson 2008)?
