Subject dispersion of LIS research in Pakistan

A subject analysis of 5195 publications in library and information science (LIS) research in Pakistan over a period of 62 years revealed that the majority of Pakistani LIS research focused on a few subject areas. Pakistani LIS researchers gave little attention to many subjects and completely ignored others. More than a quarter (26.72%) of the total items focused on “information treatment for information services” while 22% were related to “libraries as physical collections.” Other areas with some attention included “industry, profession and education” (12.32%) and “theoretical and general aspects of libraries and information” (11.40%). Researchers paid little attention to “housing technologies,” “technical services in libraries, archives and museums,” and “management.”

A new approach to collection bias in academic libraries: The extent of corporate control in journal holdings

Questions of collection bias in library journal collections usually turn on a left-right political contrast. This article presents another approach that distinguishes between corporate and non-corporate controlled publications. Using this method, the catalog holdings of all Canadian academic libraries were searched to determine the penetration of socio-political titles of mainstream “corporate publishers” and those of “small publishers.” Canadian academic libraries privilege, by a wide margin, mainstream titles published by corporate entities, although some libraries have impressive “small publisher” collections. This article also analyzed the availability of mainstream and small publisher journals provided by ten popular electronic vendors. These vendors provide very low access to non-corporate “small publisher” titles while covering 100% of surveyed mainstream titles. The implications of such provision rates are examined from the perspective of the scholarly browsing process and the role of the university.

Linking ICTs to rural development: China's rural information policy

The issue of rural communication development has been conventionally examined under labels such as universal service, digital, divide, broadband deployment, and E-Government, which generally fall into two seemingly distinct categories—access and applications. In China, these concepts are currently incorporated into a single program, if not a single term—“Village Informatization Program” (“VIP”). The VIP upgraded the objectives of previous telephone and television “Village Access Projects” (“VAPs”), an upgrade which is intended to provide “comprehensive information services” in rural areas. The execution of the VIP regime has been faced with challenges. The lack of explicitly defined objectives and institutional arrangement has led to regulatory confusion and has compromised the outcome of initiatives taken by central department and regional/local governments which are more often independent in actions. China is therefore faced with the imperative of formulating the VIP regime which is to assimilate to China's unique institutional context. This article first reviews the current status of the VIP regime before moving on to the discussion of establishing an integrative and sustainable VIP regulatory regime in China. Then, the current regulatory regime is characterized based on which reforms are suggested—in which is highlighted a layer-based localization regulatory solution, which delineates provincial/local roles from central roles based on a stratified incentive policies and governance arrangement. Possible applications in other countries are discussed in the conclusion.     

From e-government to we-government: Defining a typology for citizen coproduction in the age of social media

This paper examines the evolution of citizen coproduction in the age of social media, web 2.0 interactivity, and ubiquitous connectivity. The paper first discusses the re-emergence of citizen coproduction – whereby citizens perform the role of partner rather than customer in the delivery of public services – as a fashionable policy option in the face of persistent budget deficits and the advent of new channels for mass collaboration. Finding a plethora of competing labels, models, and concepts for coproduction in the age of social media, the paper proposes a unified typology to support systematic analysis based on the overarching categories of “Citizen Sourcing,” “Government as a Platform,” and “Do-It-Yourself Government.” To demonstrate its use, the typology is applied to leading U.S. government implementations. The paper concludes with a discussion of the potential implications for public administration, the remaining limitations and rising social concerns, and the possible emergence of a new social contract that empowers the public to play a far more active role in the functioning of their government.

The semantic mapping of words and co-words in contexts

Meaning can be generated when information is related at a systemic level. Such a system can be an observer, but also a discourse, for example, operationalized as a set of documents. The measurement of semantics as similarity in patterns (correlations) and latent variables (factor analysis) has been enhanced by computer techniques and the use of statistics; for example, in “latent semantic analysis”. This communication provides an introduction, an example, pointers to relevant software, and summarizes the choices that can be made by the analyst. Visualization (“semantic mapping”) is thus made more accessible.
