Beyond the hybrid library : libraries in a Web 2.0 world

Considers the development of social networking and the concept of Web 2.0. Looks at the implications for libraries and how traditional competences remain relevant. Explores what libraries are doing and must do to remain relevan

A macroeconomic assessment of the European Monetary Union. EUMA Paper Vol. 7, No. 5, April 2010

Since the inception of Euro in 1999, a single currency and the Economic and Monetary Union (EMU) have past more than ten years. By and large, stepping into EMU represents one of the key aspects of EU’s successful integration. For most of its short life, the European Union has been driven mainly by the goal of economic integration. From a limited experiment in economic cooperation during the early 1950s, boarded in the 1960s to become a custom union, wrestled during the 1970s with attempts to build common economic policies and exchange rate stability, focused on completing the single market during the late 1980s, to the Economic and Monetary union and a single currency at the present1, the European Union has followed a tortuous path. The paper starts with the effectiveness of EU’s monetary policy after the birth of Euro to explore the complex relationship between monetary policy and economic operation within the European Union

The Strategic Adaptation of Party Organizations to New Information and Communication Technologies : A Study of Catalan and Spanish Parties

Aquest document se centra en els casos dels dos principals partits espanyols (PP i PSOE) i catalans (PSC i CDC) en el període immediatament després de les eleccions generals espanyoles de maig de 2008, quan aquests celebraren els seus congressos. En general, es poden distingir tres tipus d'actors: en primer lloc, els ciberactivistes que tracten d'obtenir el reconeixement formal de la seva activitat en els seus partits. Així com, els líders del partit que poden intentar promoure la presència del partit en el ciberespai, però que també poden romandre indecisos perquè no és clar l'impacte electoral a la xarxa del ciberactivisme. Finalment, alguns militants tradicionals (off-line) solen ser reticents al reconeixement del ciberactivisme perquè amenaça les recompenses previstes dins del partit. Aquest article mostra com els nostres partits varen respondre al desafiament del ciberactivisme i arriba a la conclusió que la seva situació electoral, mediada per la seva ideologia, estructura organitzativa i el tipus de militància, poden ajudar-nos a comprendre el grau diferent d'institucionalització en l'organització del partit.Este documento se centra en los casos de los dos principales partidos españoles (PP y PSOE) y catalanes (PSC y CDC) en el período inmediatamente después de las elecciones generales de mayo de 2008, cuando estos celebraron sus congresos. En general, se pueden distinguir tres tipos de actores: en primer lugar, los ciberactivistas que tratan de obtener el reconocimiento formal de su actividad en sus partidos. Así como, los líderes del partido que pueden intentar promover la presencia del partido en el ciberespacio, pero que también pueden permanecer indecisos porque no está claro el impacto electoral en la red del ciberactivismo. Finalmente, algunos militantes tradicionales (off-line) suelen ser reticentes al reconocimiento del ciberactivismo porque amenaza las recompensas previstas dentro del partido. Este artículo muestra cómo nuestros partidos respondieron al desafío del ciberactivismo y llega a la conclusión de que su situación electoral, mediada por su ideología, estructura organizativa y el tipo de militancia, pueden ayudarnos a comprender el grado diferente de institucionalización en la organización del partido.This paper focuses on the cases of the two major Spanish (PP and PSOE) and Catalan parties (PSC and CDC) in the period just after the Spanish general elections of May 2008, when these parties held their party conferences. In general, three kind of actors can be distinguished: first, cyber-activists that try to get formal recognition of their activity in their parties. Then, party leaders that can try to promote the presence of the party in cyberspace but that can also remain undecided because it is not clear the net electoral impact of the cyber-activism. Finally, some traditional off-line militants are typically reluctant to the recognizance of the cyber-activism because it threatens their expected payoffs within the party. This paper shows how our parties responded to the challenge of cyber-activism and concludes that their electoral situation, mediated by their ideology, organizational structure and type of membership, can help us to understand their differential degree of party organizational institutionalization

What about the teacher? Open educational resources et al

As I began writing this proposal, serendipity struck in the form of two conversations about Open Educational Resources (OERs), one with a colleague in my own institution who has a respectable track record in innovative uses of educational technologies, another with a freelance learning facilitator engaged in full-time voluntary work. 'Without a teacher, learning is difficult and, often, impossible'. 'It took me six months to find my way around something I could have learnt in a week, if I had some stepping stones'. 'Even strongly motivated groups of learners quickly collapse without a teacher'. I was reminded of another colleague's view, of OERs as 'a modern version of a library'. In a world in which marketing and media discourses are strongly represented in widespread ideas such as 'content is free; it's a matter of editorialising', what is the role of such a library? Crucially, is there anything left for the 'teacher' in this scenario? This paper presents a reflection on those conversations, which form part of my current ethnographic research in the area of engagement with OERs. The initial findings are consistent with previous work that has highlighted the role of contextual elements in shaping a learning resource, suggesting the need to understand the assumptions upon which OERs are built as a sine qua non for meaningful re-use. The discussion suggests that the definition of OERs should be extended to include, put simply, 'the role of the teacher', even if this needs to be reinvented in multiple, perhaps not yet imagined, ways

Efficient Numerical Methods to Solve Sparse Linear Equations with Application to PageRank

In this paper, we propose three methods to solve the PageRank problem for the transition matrices with both row and column sparsity. Our methods reduce the PageRank problem to the convex optimization problem over the simplex. The first algorithm is based on the gradient descent in L1 norm instead of the Euclidean one. The second algorithm extends the Frank-Wolfe to support sparse gradient updates. The third algorithm stands for the mirror descent algorithm with a randomized projection. We proof converges rates for these methods for sparse problems as well as numerical experiments support their effectiveness.Comment: 26 page

The essence of component-based design and coordination

Is there a characteristic of coordination languages that makes them qualitatively different from general programming languages and deserves special academic attention? This report proposes a nuanced answer in three parts. The first part highlights that coordination languages are the means by which composite software applications can be specified using components that are only available separately, or later in time, via standard interfacing mechanisms. The second part highlights that most currently used languages provide mechanisms to use externally provided components, and thus exhibit some elements of coordination. However not all do, and the availability of an external interface thus forms an objective and qualitative criterion that distinguishes coordination. The third part argues that despite the qualitative difference, the segregation of academic attention away from general language design and implementation has non-obvious cost trade-offs.Comment: 8 pages, 2 figures, 3 table

Siren songs or path to salvation? Interpreting the visions of web technology at a UK regional newspaper in crisis, 2006-11

A 5-year case study of an established regional newspaper in Britain investigates journalists about their perceptions of convergence in digital technologies. This research is the first ethnographic longitudinal case study of a UK regional newspaper. Although conforming to some trends observed in the wider field of scholarship, the analysis adds to skepticism about any linear or directional views of innovation and adoption: the Northern Echo newspaper journalists were observed to have revised their opinions of optimum Web practices, and sometimes radically reversed policies. Technology is seen in the period as a fluid, amorphous entity. Central corporate authority appeared to diminish in the period as part of a wider reduction in formalism. Questioning functionalist notions of the market, the study suggests cause and effect models of change are often subverted by contradictory perceptions of particular actions. Meanwhile, during technological evolution, the ‘professional imagination’ can be understood as strongly reflecting the parent print culture and its routines, despite pioneering a new convergence partnership with an independent television company

Revisiting digital technologies: envisioning biodigital bodies

In this paper the contemporary practices of human genomics in the 21st century are placed alongside the digital bodies of the 1990s. The primary aim is to provide a trajectory of the biodigital as follows: First, digital bodies and biodigital bodies were both part of the spectacular imaginaries of early cybercultures. Second, these spectacular digital bodies were supplemented in the mid-1990s by digital bodywork practices that have become an important dimension of everyday communication. Third, the spectacle of biodigital bodies is in the process of being supplemented by biodigital bodywork practices, through personal or direct-to-consumer genomics. This shift moves a form of biodigital communication into the everyday. Finally, what can be learned from putting the trajectories of digital and biodigital bodies together is that the degree of this communicative shift may be obscured through the doubled attachment of personal genomics to everyday digital culture and high-tech spectacle.Keywords: genomics, biodigital, bodies, spectacle, everyda

Fitting heavy tailed distributions: the poweRlaw package

Over the last few years, the power law distribution has been used as the data generating mechanism in many disparate fields. However, at times the techniques used to fit the power law distribution have been inappropriate. This paper describes the poweRlaw R package, which makes fitting power laws and other heavy-tailed distributions straightforward. This package contains R functions for fitting, comparing and visualising heavy tailed distributions. Overall, it provides a principled approach to power law fitting.Comment: The code for this paper can be found at https://github.com/csgillespie/poweRla
