VALUE IN THE MASH: EXPLORING THE BENEFITS, BARRIERS AND ENABLERS OF OPEN DATA APPS
The open government paradigm relies on the provision and reuse of open government data (OGD) to improve transparency and create new sources of valu. This study aims to progress understanding of OGD beyond a theoretical commentary by exploring the perceived sources of valu of mashups (online services that combine diverse OGD), and to examine issus that impact on, and facilitate, the delivery of this valu from an ËinsiderÂŽ perspective. Based on open-ended interviews with 17 individuals actively involved in OGD application design, use, and advocacy in New Zealand (ranked fourth in the 2013 Global Open Data Barometer) nine key sources of valu were identified: Ease of discovery, improved data quality, bringing knowledge into relevant contexts, economic benefits, social benefits, cost reduction and efficiencies, predictive valu, transparency, and ability to explore and play. Twelve barriers to delivering this valu were found, ranging from change-related issus to problems relating to sustainability. Six facilitators were identified as helping to overcome these barriers and realise the valu of OGD
Locating frames of reference for information systems : a position paper
Frame analysis has been applied in Information Systems (IS) research to generate understanding of such issues as organisational change and IS implementation. Frames are the unconscious interpretive schemas that people, or groups of people, use to interpret their surroundings, determine what is important, and guide their actions. While framing has been used as a theoretical lens in IS research into organisations, there has been no analysis to date of how frames may play a role in the IS field itself. This paper argues that is relevant and insightful to examine the IS discourse from a framing perspective. In order to demonstrate the potential value of such an approach, a subset of a collection of articles from six journals in the senior scholars’ basket of journals was analysed in an exploratory attempt to locate the frames of reference that predominate in the IS discourse. Three levels of framing were identified and a provisional schema is proposed. We suggest that further investigation of the schema, the frames and their application will provide opportunity for critical reflection on the nature of Information Systems as an academic discipline. Such critical self-examination may even foster purposive frame breaking, in support of recent calls for transformation in the IS field.<br /
Cybersecurity Maturity in the Pacific Islands â Informing a Regional CERT Framework
Cybersecurity acts as a strong influence on national governmentsâ security, economic, physical and social interests. A common policy goal of governments is to protect their respective interests by supporting cybersecurity threat and attack response capabilities. Contemporary research addresses the use of multi-national CERT frameworks to improve national cybersecurity capability maturity and resilience, however little research has been conducted into the efficacy of such frameworks with Pacific Island nations. This research employs a qualitative interview technique to develop an inductive model for a regional Pacific Islands CERT framework. The research proposes a Pacific Islands regional model based on a network of affiliated national CERTs that operate independently and reflect their respective national interests, while collaborating on matters of shared interest, supported by regional partners providing targeted assistance to build national and regional cybersecurity capability maturity and resilience
UNPACKING THE SUBJECTIVE NORM: APPLYING STRUCTURATION THEORY TO TRADITIONAL MEASURES OF SOCIAL INFLUENCE
This study took place within the context of a larger project seeking to identify the factors that are associated with the acceptance and use of electronic recordkeeping systems in public sector organizations. This class of system relies on ordinary end-users to choose to select and file appropriate records into the system in order to comply with organizational and legislative recordkeeping requirements. The use of such a system necessarily includes a social or organizational context dimension to explain the intention to use. This paper focuses on the construct validity associated with social influence within the research model. This particular construct traces its roots back to the 1970s and appears in much of the technology acceptance literature as the subjective norm. The measures and techniques for identifying construct validity prior to the development of a survey instrument, and subsequent measures and techniques for detecting construct validity after gathering the detailed survey dataset, are discussed. The techniques used to group the measurement items by construct, and thus into a survey instrument, included card sorting and the use of cluster analyses and dendrograms. After the survey instrument data collection activity, the detailed construct validity analysis utilized the circle of correlations based on a principal component analysis.The research found that the traditional measures of social influence constructs cluster well, but are in fact multidimensional. Furthermore, the dimensionality revealed by the statistical analysis aligns with and supports the predicted interactions of society as put forward in Giddensâ Structuration Theory. This finding lends empirical support to Structuration Theory and underscores the importance of construct validity, particularly in the current push to increase the âsocialâ aspects of technology
Factors Influencing Employees\u27 Intention to Use an Electronic Recordkeeping System: Development of a Valid Survey Instrument
This study seeks to identify the factors that are associated with the acceptance and use of electronic recordkeeping systems in public sector organisations. These systems rely on ordinary end-users (rather than trained recordkeepers) to select and file appropriate records to comply with organisational and legislative recordkeeping requirements; however, current acceptance and utilisation rates of these systems are often mixed. The selected methodology is a mixed-methods approach, with this paper focusing on the development of a valid survey instrument. A theoretical model was initially derived from the literature covering three logical areas (and consisting of their supporting and pre-validated constructs): Technology Acceptance (performance expectancy, effort expectancy); Organizational Context (social influence, perceived power security), and Knowledge Interpretation. A new construct â perceived value of records â is introduced in this study to provide a construct in support of Knowledge Interpretation. The derived measurement items are then checked for construct validity before forming a suitable survey instrument
Understanding Cloud ERP Adoption Phenomenon: Large Organizational Perspective
Ushered by the emergence of cloud computing technologies in the late 2000s, cloud enterprise resource planning (ERP) systems are becoming the ânew normalâ as organizations are migrating their on-premise ERP to the cloud. Consensus in the literature indicates the criticality of transition to cloud based technologies fraught with both benefits and risks. Experts have advocated for extensive judgement and insights of IT decision makers, which are more applicable for large organizations. A research model, influenced by the theory of reasoned action (TRA) and ambidexterity construct, has been developed to understand senior managersâ decision-making process for cloud ERP adoption. Being exploratory and theory building in nature, multi-case study method will be applied. This study is expected to contribute to innovation adoption literature as well as help in clientsâ better understanding for resolution of decisional dilemma in case of complex system adoption such as cloud ERP
Serine, but not glycine, supports one-carbon metabolism and proliferation of cancer cells
Previous work has shown that some cancer cells are highly dependent on serine/glycine uptake for proliferation. Although serine and glycine can be interconverted and either might be used for nucleotide synthesis and one-carbon metabolism, we show that exogenous glycine cannot replace serine to support cancer cell proliferation. Cancer cells selectively consumed exogenous serine, which was converted to intracellular glycine and one-carbon units for building nucleotides. Restriction of exogenous glycine or depletion of the glycine cleavage system did not impede proliferation. In the absence of serine, uptake of exogenous glycine was unable to support nucleotide synthesis. Indeed, higher concentrations of glycine inhibited proliferation. Under these conditions, glycine was converted to serine, a reaction that would deplete the one-carbon pool. Providing one-carbon units by adding formate rescued nucleotide synthesis and growth of glycine-fed cells. We conclude that nucleotide synthesis and cancer cell proliferation are supported by serineârather than glycineâconsumption
