Impulse excitation measurement of small changes in elastic moduli and damping using R

Impulse excitation is commonly used to assess wood stiffness in both scientific and industrial settings. Modes of vibration are excited by a mechanical impulse and their resonant frequencies measured to calculate elastic moduli. It is also possible to assess damping, which is an important property for wood used in musical instruments. This paper covers finer details of the signal analysis necessary when making very accurate measurements. Provided code for Open Source statistical software R is illustrated with data from an experiment tracking small changes in Douglas-fir clear wood during thermal treatment. A frequency domain interpolation method is introduced that enhances the potential precision of the technique to a very high degree, with computational efficiency, even when using inexpensive audio equipment. With multiple measurements, resonant frequencies can be assessed to a precision of 0.1 Hz and better, allowing for tracking of very small changes due to wood treatments or moisture content

A Literature Review on Cloud Computing Adoption Issues in Enterprises

Part 3: Creating Value through ApplicationsInternational audienceCloud computing has received increasing interest from enterprises since its inception. With its innovative information technology (IT) services delivery model, cloud computing could add technical and strategic business value to enterprises. However, cloud computing poses highly concerning internal (e.g., Top management and experience) and external issues (e.g., regulations and standards). This paper presents a systematic literature review to explore the current key issues related to cloud computing adoption. This is achieved by reviewing 51 articles published about cloud computing adoption. Using the grounded theory approach, articles are classified into eight main categories: internal, external, evaluation, proof of concept, adoption decision, implementation and integration, IT governance, and confirmation. Then, the eight categories are divided into two abstract categories: cloud computing adoption factors and processes, where the former affects the latter. The results of this review indicate that enterprises face serious issues before they decide to adopt cloud computing. Based on the findings, the paper provides a future information systems (IS) research agenda to explore the previously under-investigated areas regarding cloud computing adoption factors and processes. This paper calls for further theoretical, methodological, and empirical contributions to the research area of cloud computing adoption by enterprises

Understanding eParticipation services in indonesian local government

Published version of a chapter in the book: Information and Communication Technology. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-55032-4_32This study aims at understanding how local government from a developing country, in this case Indonesia, implement and manage eParticipation services. In doing so, we combine institutional theory and stakeholder theory to build a sharper analytical lens. From an interpretive case study in the city of Yogyakarta, we reveal the institutionalization process of the services since their inception and identify major stakeholders and their salience. Based on our findings, we propose implications for practice and suggest implications for further research. Future work, based on a multiple case strategy including several eParticipation cases from other parts of Indonesia, will further explore the findings reported here

A dynamic capabilities perspective of IS project portfolio management

Organizations use information systems project portfolio management (IS PMM) to reconfigure their IS resources and capabilities to match changing market and economic conditions. IS PPM can therefore be characterised as a dynamic capability. We investigate how firms developed and adapted IS PPM to match the turbulent recessionary conditions witnessed after 2008–09. This study contributes to an understanding of IS PPM by identifying the constituent dynamic capabilities and providing empirical examples of adaptation. To our knowledge, the study is the first to apply the notion of second order dynamic capabilities to the IS domain and also makes an important contribution to the more general concept of dynamic capabilities by providing empirical evidence and theoretical justification of the increased detailed, centrally controlled and analytical nature of IS PPM dynamic capabilities in recessionary conditions

Mobile applications as carriers of institutional pressures:a case of the Finnish taxi industry

Abstract While the worldwide market expansion of Uber has raised controversy, Uber has also received praise for its mobile phone app. Its many features — taxi ordering, pricing, real-time location information, paying, and service evaluation — have provided significant customer value. When Uber entered Finland in November 2014, few other taxi apps were available. Between 2014 and 2018, this shortage of taxi apps turned into an abundance, with many companies introducing their own taxi apps. By leaning on institutional theory, and more specifically by applying coercive, mimetic and normative pressures as a lens, we provide an explanation for why three Finnish taxi apps now resemble Uber in some features, whereas they differ in others. Based on our interviews, we can explain the present-day differences between these apps by coercive and normative pressures in the institutional environment of the Finnish taxi industry. We contribute to the IT and institutionalization research stream by illustrating how mobile applications as IT artefacts can be seen as carriers of institutional pressures materializing in the features they provide

Legitimation of E-Government Initiatives: A Study of India’s Identity Project

Part 5: IT in the Public SectorInternational audienceLegitimation is an important aspect of e-government initiatives due to the complex and diverse issues related to policy and technology implementation which create huge demands for resources. Legitimation is one of the core concepts of Institutional theory. Though institutional theory is gaining importance in IS and e-government research, there are very few studies on the strategies and process of legitimation in e-government implementations. In this paper we use institutional theory and examine the institutionalization of India’s Unique Identification (UID) project. Given the novelty and uniqueness of the UID initiative, we find that the predominant strategy used is that of conformance and proactive manipulation of the environment. The main contribution of the paper is in identifying that different strategies are used for supply side and demand side stakeholders of e-government projects
