Factors affecting Web 2.0 adoption: exploring the knowledge sharing and knowledge seeking aspects in health care professionals

Jang Bahadur Singh, Rajesh Chandwani, and Mayank Kumar

Journal of Knowledge Management

Purpose

This research aims to explore the factors that affect the adoption of Web 2.0 among knowledge workers. The research specifically investigated the role of factors related to both knowledge seeking and knowledge sharing, in the context of Web 2.0 use by health care professionals.

Design/methodology/approach

For this research, a cross-sectional survey design was adopted. The data were analyzed using the partial least square-structural equation modeling.

Findings

The results confirmed that the intention to adopt Web 2.0 depends upon both the knowledge-seeking and the knowledge-sharing attitudes. However, between the two, it is knowledge-sharing factors that are more important. Health care professionals tend to share knowledge driven by intrinsic motivators rather than by extrinsic motivators. On the other hand, knowledge-seeking attitude was determined by usefulness of knowledge and was not affected by the effort involved.

Research limitations/implications

All the respondents were health care professionals from India, and convenience sampling was used to reach them. This may limit the generalizability of the findings.

Practical implications

This research provides useful insights on implementing Web 2.0-based knowledge management systems, specifically for health care professionals. Particularly, it emphasizes the need to focus on reinforcing intrinsic motivators like self-efficacy and the joy of sharing.

Originality/value

It is perhaps the first study that integrates the factors related to knowledge sharing and seeking in a single theoretical model, thereby presents and tests a more realistic model of knowledge management.

Two-stage test of means of unordered pairs

Tathagata Banerjee Gaurangadeb Chattopadhyay and Kaustav Banerjee

Statistics in Medicine

The problem of testing equality of means of a bivariate normal distribution on the basis of a sample of size n has been considered when the labels of the observations are either missing or not known. The problem may arise in many applied settings, especially in genetics. Classical likelihood ratio test fails here because of identifiability problems. We propose a two-stage testing procedure using a recently developed test in the context of penalized splines. The proposed testing procedure is found to outperform the tests proposed in the literature. Copyright © 2017 John Wiley & Sons, Ltd.

Rehabilitation myths? How transaction costs reduce farmer welfare after land acquisition.

Vikram Patil and Ranjan Kumar Ghosh

Journal of South Asian Development

In this article, we show how transaction costs lead to farmer marginalization as displaced farmers embark on the process of acquiring new land. Existing studies have focused on the links between monetary compensation and landowners’ investment decisions, but before new land is acquired. However, the post-displacement scenario and the investment decisions of land owners to restore income have not been carefully examined. We use a transaction cost framework to suggest that local specificities related to land characteristics, uncertainties in search for alternatives and information constraints may impose high non-monetary costs on displaced farmers and force them to settle for inferior new land. The article concludes with a preliminary assessment of whether the newly enacted land acquisition framework, the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement (RFCTLARR) Act 2013, promises to minimize these ex-post transaction costs that farmers face.

Critique of recent revisions with base year change for estimation of state income in India

Ravindra H. Dholakia and Manish B. Pandya

Journal of Indian School of Political Economy

In the present paper, we have critiqued recent revisions made in the estimation of state income in India consequent upon the change in the base year of the National Accounts from 2004-05 to the new base of 2011-12. We have pointed out 10 major limitations of the whole exercise. The revisions associated with the new base 2011-12 series have serious implications on national and regional accounts estimation compared to the past. We have argued with concrete illustrations drawn from the experience of the Gujarat state that most of these impacts are negative on the quality, reliability, valid usage, interpretation and meaningful analysis of long term trends of sectors and the economy at the state level in the country. These revisions areperhaps not well thought out, carefuland consistent with the fundamental desirable characteristics of descriptive statistics and estimation of aggregates. In some cases they seem to be carried out hurriedly without paying attention to their likely impact on the whole system, processes and personnel involved in collection, compilation and generation of critical estimates at regional level. Our final recommendation is that the recent revisions associated with the new base of 2011-12 series should be abandoned for implementation at the state and district levels in the country till further revision of the base year takes place. In the interim period, let the old base of 2004-05 with the methodology continue at the state level.

How Costly is the Deliberate Disinflation in India? – Estimating the Sacrifice Ratio

Ravindra H. Dholakia and Kadiyala Sri Virinchi

Journal of Quantitative Economics

Methods followed in earlier studies for estimating the sacrifice ratio or the real cost of deliberate disinflation have focused only on aggregate supply side ignoring aggregate demand. The present study considers the adjustment path obtained as a locus of short run equilibria to arrive at a theoretically acceptable sacrifice ratio. The study uses quarterly data from the period between 1996-97Q1–2013-14Q4 in India and employs both the regression as well as the direct methods to estimate the ratio. The results have revealed a sacrifice ratio ranging from 1.7 to 3.8 depending on the method and the measure of inflation used. Such a magnitude of the real cost of disinflation in India, also relevant in the medium to long run, clearly contradicts the dominant view among policymakers that the trade-off, if any, is negligible. Deliberate disinflation policy needs to consider the real cost of sacrificing output and employment particularly when its magnitude is substantial.

Framework for evolving spectrum management regimes: Lessons from India

Rekha Jain and Rishabh Dara

Telecommunications Policy

India has seen a marked change in spectrum policy over the past decade from a legacy administrative regime to a more market oriented one wherein it has adopted auctions in the primary market, trading in the secondary market and has liberalised spectrum to make it technology and service neutral. It has faced numerous challenges, constraints, and legacy issues in its transition, thus providing a rich context for analysis. Using the case study of India, we developed a framework that highlights the various dimensions to be considered while migrating from an administrative to a market regime for spectrum management. The framework also helps to assess the current orientation of a spectrum policy regime and provides a direction for adopting a higher market orientation. We used the framework in the Indian context to show that while India had adopted market mechanisms, it had a low level of market orientation.

This place is not the same anymore; temps are coming in

Saikat Chakraborty

Business Review India

As organisations increasingly rely on temporary work arrangements, there is a significant rise in the proportion of workers in part-time, contractual, fixed tenure, and other such labour engagements. Due to the difference between the employment relationships of temporary and permanent workers, corporations often design separate control mechanisms for these two worker groups. This paper argues that organisational control of workers extensively shapes their organisational communication. Communication as constitutive of organisation (CCO) research says that the interaction between members and objects plays a vital role in constructing ‘communication yielding organising.’ The emergent organisation rests on the negotiations of conversations and texts which carry the ongoing organisational communication. Workplaces in which the workforce composition is shifting from permanent workers to a mixture of permanent and temporary workers gradually realise pertinent changes in their conversations and texts, which as carriers of organisational communication constitutes how the organisation emerges as well.

Using narratives in creativity research: Handling the subjective nature of creative process

Saikat Chakraborty

The Qualitative Report

For most of us, creative processes are those which can produce outcomes that are capable of being judged as creative. The outcome-centric recognition of creativity has heavily downplayed the process-perspective of creativity in organizations. Influenced significantly by individual and social subjectivities, creative processes are difficult to enquire on the basis of positivist approaches presently dominating creativity research. Use of narrative methodology in creativity research is proposed as a strategy for not just handling the subjectivities but also for making meaning from them as well as from participants' emotions. Antenarratives can help to enrich the narrated storyline, and personal narratives of the researcher allows to tie back the subjectivities through co-created meanings. The article aspires to invigorate attention towards the foundations of creativity research that has offered little scope for research paradigms that are beyond the objective-positivist tradition. Consequently, it urges the research community to seek suitable methodologies like the narrative which promises to explore the process-perspective of creativity and enlarge our organizational understanding of creativity.

HMiner: Efficiently mining high utility itemsets

Srikumar Krishnamoorthy

Expert Systems with Applications

High utility itemset mining problem uses the notion of utilities to discover interesting and actionable patterns. Several data structures and heuristic methods have been proposed in the literature to efficiently mine high utility itemsets. This paper advances the state-of-the-art and presents HMiner, a high utility itemset mining method. HMiner utilizes a few novel ideas and presents a compact utility list and virtual hyperlink data structure for storing itemset information. It also makes use of several pruning strategies for efficiently mining high utility itemsets. The proposed ideas were evaluated on a set of benchmark sparse and dense datasets. The execution time improvements ranged from a modest thirty percent to three orders of magnitude across several benchmark datasets. The memory consumption requirements also showed up to an order of magnitude improvement over the state-of-the-art methods. In general, HMiner was found to work well in the dense regions of both sparse and dense benchmark datasets.
