Exploring the determinants of knowledge sharing via employee weblogs

Weblogs have been used by organisations as both a communication means and a knowledge sharing tool. Traditionally, research has explored the use of weblogs and virtual communities for knowledge sharing. Nevertheless, relatively little has been published focusing on the factors that influence the intention to share knowledge in employee weblogs. This paper aims to address this gap based on a survey of 175 respondents. The results indicate that self-efficacy, perceived enjoyment, certain personal outcome expectations, and individual attitudes towards knowledge sharing are positively related to the intention of knowledge sharing in employee weblogs.

Social media for openness and accountability in the public sector: cases in the Greek context

This paper explores the use of government social media for opennessand accountability. The extant literature has highlighted the benefits of social media use in this context to enhance citizen participation and engagement in decision-making and policy development, facilitate openness and transparency efforts, and reduce corruption. Yet, there are limited studies that discuss those properties of social media that can afford openness and accountability, and their implications for policy and practise. To address these gaps, a study is conducted in the Greek context using interviews with top managers, policy makers, and relevant stakeholders across five initiatives. We discuss distinct affordances for openness and accountability, and propose their inclusion as building blocks of the national ICT policy for openness and accountability. Finally, we provide the implications of the affordances lens for policy and practise, the limitations of the study and future research avenues.

Exploring the impact of cultural values on project performance: The effects of cultural values, age and gender on the perceived importance of project success/failure factors

Purpose – This study aims to explore the impact of cultural values on the importance individuals assign to project success/failure factors (PSFFs). Design/methodology/approach – Themes emerging from 40 interviews of project practitioners based in Brazil, China, Greece, Nigeria, Thailand, the UAE, the UK and the USA are integrated with literature evidence to design a survey instrument. One thousand three hundred and thirteen practitioner survey responses from the eight countries are analysed using multi-group, structural equation modelling. Findings – Ten project success/failure indicators (PSFIs) are found to reduce to two main PSFFs: project control and extra-organisational goals and project team management/development and intra-organisational goals. It is found that the levels of importance individuals assign to both factors are dependent, not only on age and gender, but also cultural values measured as constructs based on Hofstedes individualism, masculinity, power distance and uncertainty avoidance d...

SQ mGov: A Comprehensive Service-Quality Paradigm for Mobile Government

Service quality of Mobile Government (mGov) is an important concept; however, to date, there has been relatively little work conducted in this emerging area. Based on an empirical study conducted among 1404 users of mGov in Mumbai, India, this study conceptualizes and identifies four service-quality dimensions—connectivity, interactivity, understandability, and authenticity—as the formative constructs of mGov service quality, and 16 measuring items to evaluate those dimensions as the reflective indicators.

What drives eGovernment growth? An econometric analysis on the impacting factors

This study contributes to the current literature of eGovernment adoption, by proposing a parsimonious, yet comprehensive model, based on three socio–economic theories namely, institutionalism, endogenous and exogenous growth. Using this framework as the guiding theoretical lens, critical factors are identified, while their impact is evaluated with an econometric analysis on secondary, country level data. The study especially highlights on the use of OSS technology and its implications into the eGov context. Findings suggest that countries with advanced technologies, education, technological openness and effective governance and regulation lead eGovernment adoption.

The Ontology of the OSS Business Model: An Exploratory Study

This study focuses on theory building providing a holistic conceptual framework that consists of an ontology based OSS business model and an OSS business model taxonomy. The study extends existing theory in OSS business models and corresponding taxonomies, based on the structured-case methodological approach. An exploratory study is conducted in two research cycles, for the identification, validation, and evaluation of the critical constructs of an OSS business model. Results reveal that OSS business models differ from traditional software business models, having specific features that affect the software value chain, the infrastructure, and the revenue model of an OSS oriented firm.

Exploring intentions towards human, social and financial capital investments in a turbulent economic environment:

This article applies the theory of planned behaviour in order to understand intentions to create new ventures or participate in existing ones, by investing human, social and financial capital in a turbulent economic environment, such as the one in Greece. We hypothesize that subjective norms relate to investment intentions (IIs) and that individual attitudes and perceived behavioural control over the investment mediate this relationship. We also propose that norms, attitudes and control interact in explaining IIs in such a way that intentions are stronger when positive norms and attitudes coexist with high levels of control. Hypotheses are tested by means of a cross-sectional quantitative study that was conducted in Greece (N = 203). Bootstrap analyses support our mediation hypotheses by showing that norms relate positively to IIs via their associations with positive attitudes and high control. In addition, regression analyses show that norms, attitudes and control interact in explaining intentions. However, contrary to expectations, results show that positive attitudes towards investment boost IIs, in conditions where norms are positive but control is low.

Capital, Motives, and Their Link to Investment Intentions: The Moderating Role of the Financial Crisis in Greece

This research examined the moderating role of the financial crisis on the relationship between capital/motives and investment intentions. Human and social capital, nonfinancial resources, and all motives except financial success related positively to investment intention. Social capital and the motive for financial success related positively to investment intention only for those affected by the crisis in a negative way. The motives for independence and recognition related positively to investment intention only for those affected by the crisis in a positive way, while the motive of self‐realization related positively to investment intentions particularly for those affected by the crisis in a positive way.

Does OSS Affect E-Government Growth? An Econometric Analysis on the Impacting Factors

Inspired by the OSS values, an increasing number of different forms of open initiatives have come to the fore. In the context of eGovernment the notion of open government has met wide acceptance among nations and became closely related to one of its goals. Open government shares with OSS the notions of collaboration, participation and transparency and many actions towards OSS into eGovernment reform policies, have been recorded worldwide. The study investigates the relationship between OSS growth and eGovernment. A theoretical framework of the theories of institutionalism, growth and human capital is proposed as the guiding theoretical lens to identify possible influencing factors that together with OSS are evaluated for their magnitude of impact on eGovernment growth across different economic environments.

Challenges of Complex Information Technology Projects: The MAC Initiative

Although painstaking planning usually precedes all large IT development efforts, 80% of new systems are delivered late (if ever) and over budget, frequently with functionality falling short of contract. This case study provides a detailed account of an ill-fated initiative to centrally plan and procure, with the aim to homogenize requirements, an integrated applications suite for a number of British higher education institutions. It is argued that because systems are so deeply embedded in operations and organization and, as you cannot possibly foresee and therefore plan for environmental discontinuities, high-risk, ‘big-bang’ approaches to information systems planning and development must be avoided. In this context the case illustrates the level of complexity that unpredictable change can bring to an information technology project that aims to establish the ‘organizationally generic’ and the destabilizing effects it has on the network of the project’s stakeholders.
