information seeking as explorative learning

The paper starts with an overview of major problems hindering effective interactions with information retrieval systems. A brief review of models of the interaction taking place during information seeking is then provided with the aim of lying the ground for yet another model based on two levels of interaction: presentation and navigation. The former encompasses interactions with the user interface of the retrieval system, whereas the latter deals with the interaction that users experience with the information resource. It is claimed that this second level of interaction can be framed as an exploratory learning process and that its analysis provides adequate support for designing and evaluating information access systems

Firms, Incomplete Contracts and Organizational Learning

This explorative paper argues that the central problem of economic organization is adaptation to unforeseen contingencies. However, flexibility is a rather neglected issue in the theory of economic organization. This contrasts with much organization theory, in which the seeking and processing of information about the organization's key uncertainties is seen as a determinant of organizational form. The notion of incomplete contracts is argued to provide a means to bridging ideas from organizational economics and organization theory, particularly organizational learning. Incomplete contracts are not only important because they provide room for incentive problems, but more importantly because they allow firms to exploit processes of organizational learning that must always involve some unforeseen contingencies. Firms are seen as efficient institutional responses to learning processes that involve strongly complementary problem-solving activities.The theory of economic organization, incomplete firm contracts, organizational learning, t

Knowledge management practices and the enhancement of customer capital: the importance of time

Actualmente, los responsables de las pequeñas y medianas empresas (PYMES) debido al hecho de tener que vigilar continuamente sus empresas a la búsqueda de mejoras en las relaciones con sus clientes y trabajadores, están otorgando un papel cada vez más estratégico a las prácticas de gestión del conocimiento. No obstante, hay situaciones donde las organizaciones y sus miembros se enfrentan a entornos cada vez más inciertos, por lo que es necesario reconsiderar las prácticas de gestión del conocimiento que se han venido desarrollando en la empresa desde sus inicios. Estas prácticas, en forma de procesos y rutinas, pueden basarse tanto en conocimiento tácito como explícito y también necesitan ser continuamente reconsideradas de cara a la captación de nuevo conocimiento. En tales circunstancias, sería necesario modificar e incluso eliminar parte del conocimiento existente al objeto de asegurarnos de que los empleados tienen acceso a conocimientos lo suficientemente actualizados como para que mantengan o garanticen las relaciones que las PYMEs tienen con sus clientes. Nuestro trabajo examina el impacto que un contexto de “mentalidad abierta” (openminded) en la organización existente en un momento dado (T) tiene sobre las actuaciones que intentan reconsiderar los conocimientos organizativos en un momento posterior (T+1). Analizamos además la relaciones entre los procesos de aprendizaje/conocimiento explorativo y aplicado sobre el capital relacional. Se utiliza para ello evidencias empíricas procedentes de 107 PYMES del sector de las telecomunicaciones en España, utilizando la técnica PLS.Actualmente, los responsables de las pequeñas y medianas empresas (PYMES) debido al hecho de tener que vigilar continuamente sus empresas a la búsqueda de mejoras en las relaciones con sus clientes y trabajadores, están otorgando un papel cada vez más estratégico a las prácticas de gestión del conocimiento.

A Balancing-Process Approach to Firm Internationalization

Drawing on the resource-based view of the firm, this paper develops a balancing-process approach to explain the motivations and location choices of foreign direct investment (FDI). In this approach, FDI is viewed as a means to balance a firm's portfolio of resources and capabilities through utilizing foreign strategic factor markets with the ultimate goal of achieving growth and sustainable competitive advantage. This approach joins exploitative and explorative FDI in a single framework and helps explain why a firm can conduct both types of FDI simultaneously.

Cerebellar BDNF promotes exploration and seeking for novelty

Approach system considered a motivational system that activates reward-seeking behavior is associated with exploration/impulsivity, whereas avoidance system considered an attentional system that promotes inhibition of appetitive responses is associated with active overt withdrawal. Approach and avoidance dispositions are modulated by distinct neurochemical profiles and synaptic patterns. However, the precise working of neurons and trafficking of molecules in the brain activity predisposing to approach and avoidance are yet unclear

"Do screen captures in manuals make a difference?": a comparison between textual and visual manuals

Examines the use of screen captures in manuals. Three types of manuals were compared: one textual and two visual. The two visual manuals differed in the type of screen capture that was used. One had screen captures that showed only the relevant part of the screen, whereas the other consisted of captures of the full screen. All manuals contained exactly the same textual information. We examined immediate use on time (use as a job aid) and on learning (use as a teacher). For job-aid purposes, there was no difference between the manuals. The visual manual with full-screen captures and the textual manual were both better for learning than the visual manual with partial screen captures. We found no effect on user motivation. The tentative conclusion of this study is that screen captures seem not to be vital for learning or immediate use. If one opts for including screen captures, then the conclusion is that full-screen captures are better than partial one

Safe environments for innovation: developing a new multidisciplinary masters programme

This paper outlines the research and resulting curriculum design activities conducted as a collaborative venture between Northumbria University’s School of Design, School of Computing, Engineering and Information Sciences and Newcastle Business School undertaken in the creation of a new postgraduate programme in Multidisciplinary Design Innovation. With the area of multidisciplinary innovation education practice being comparatively new, the research conducted in support of the programme development was undertaken through a series of industry-linked pilot-study projects conducted with Philips, Hasbro, Lego and Unilever. The key finding from this research was an understanding of the importance of freeing students from different disciplines of the inhibitions that limit creativity in collaborative settings. This paper gives an account of the pilot studies and the associated learning derived from them, the collaborative development of the programme and approaches in curriculum and assessment design adopted in order to create what we call ‘safe environments for innovation’; environments designed to free students of these evident inhibitions

Children searching information on the Internet: Performance on children's interfaces compared to Google

Children frequently make use of the Internet to search for information. However, research shows that children experience many problems with searching and browsing the web. The last decade numerous search environments have been developed, especially for children. Do these search interfaces support children in effective information-seeking? And do these interfaces add value to today’s popular search engines, such as Google? In this explorative study, we compared children’s search performance on four interfaces designed for children, with their performance on Google. We found that the children did not perform better on these interfaces than on Google. This study also uncovered several problems that children experienced with these search interfaces, which can be of use for designers of future search interfaces for children

Viewing the personality traits through a cerebellar lens. A focus on the constructs of novelty seeking, harm avoidance, and alexithymia

The variance in the range of personality trait expression appears to be linked to structural variance in specific brain regions. In evidencing associations between personality factors and neurobiological measures, it seems evident that the cerebellum has not been up to now thought as having a key role in personality. This paper will review the most recent structural and functional neuroimaging literature that engages the cerebellum in personality traits, as novelty seeking and harm avoidance, and it will discuss the findings in the context of contemporary theories of affective and cognitive cerebellar function. By using region of interest (ROI)- and voxel-based approaches, we recently evidenced that the cerebellar volumes correlate positively with novelty seeking scores and negatively with harm avoidance scores. Subjects who search for new situations as a novelty seeker does (and a harm avoiding does not do) show a different engagement of their cerebellar circuitries in order to rapidly adapt to changing environments. The emerging model of cerebellar functionality may explain how the cerebellar abilities in planning, controlling, and putting into action the behavior are associated to normal or abnormal personality constructs. In this framework, it is worth reporting that increased cerebellar volumes are even associated with high scores in alexithymia, construct of personality characterized by impairment in cognitive, emotional, and affective processing. On such a basis, it seems necessary to go over the traditional cortico-centric view of personality constructs and to address the function of the cerebellar system in sustaining aspects of motivational network that characterizes the different temperamental trait

An adaptive technique for content-based image retrieval

We discuss an adaptive approach towards Content-Based Image Retrieval. It is based on the Ostensive Model of developing information needs—a special kind of relevance feedback model that learns from implicit user feedback and adds a temporal notion to relevance. The ostensive approach supports content-assisted browsing through visualising the interaction by adding user-selected images to a browsing path, which ends with a set of system recommendations. The suggestions are based on an adaptive query learning scheme, in which the query is learnt from previously selected images. Our approach is an adaptation of the original Ostensive Model based on textual features only, to include content-based features to characterise images. In the proposed scheme textual and colour features are combined using the Dempster-Shafer theory of evidence combination. Results from a user-centred, work-task oriented evaluation show that the ostensive interface is preferred over a traditional interface with manual query facilities. This is due to its ability to adapt to the user's need, its intuitiveness and the fluid way in which it operates. Studying and comparing the nature of the underlying information need, it emerges that our approach elicits changes in the user's need based on the interaction, and is successful in adapting the retrieval to match the changes. In addition, a preliminary study of the retrieval performance of the ostensive relevance feedback scheme shows that it can outperform a standard relevance feedback strategy in terms of image recall in category search
