Understanding cloud computing adoption issues: A Delphi study approach
2016
An exploratory ranking-type Delphi study and follow-up interviews were conducted.Important cloud computing adoption issues are identified, categorized and ranked.Three subpanels top-ranked issues from security, strategy and legal categories.A framework of inhibitors and drivers for cloud computing adoption is proposed.Recommendations to assist decision-makers in cloud computing adoption are proposed. This research paper reports on a Delphi study focusing on the most important issues enterprises are confronted with when making cloud computing (CC) adoption decisions. We had 34 experts from different domain backgrounds participated in a Delphi panel. The panelists were IT and CC specialists r…
Organizational Culture Challenges of Adopting Big Data: A Systematic Literature Review
2019
Part 2: Big Data Analytics; International audience; The interest of adopting big data (BD) in organizations has emerged in recent years. Even though many organizations have attempted to adopt BD, the benefits gained by this investment has been limited, and organizations struggle to fully utilize the potential of BD. There has been done several studies on the different challenges and benefits that may occur during the process of adopting and using BD. One major factor that has been discussed in the literature to overcome such challenges has been organizational culture. This paper aims to provide a systematic literature review that reports the organizational culture’s impact on BD adoption th…
Constructing Interdependencies with Collaborative Information Technology
2000
Interdependence construction is the gradual formation of mutual relationships between people. In this study, the area is narrowed to interdependencies at work, in long term projects or groups. Viewing interdependence relationships dynamically, as social practices, it is possible to appreciate the complex and situated nature of this formation. The main goal of the study is to develop a theoretical account of the dynamics of the intertwined processes of interdependence construction and collaborative technology appropriation and use. The main dimensions of this account are: (1) how interdependence is constructed and established as a social process, (2) how information and communication are inv…
Managing information security in a business network of machinery maintenance services business – Enterprise architecture as a coordination tool
2007
Today, technologies enable easy access to information across organizational boundaries, also to systems of partners in business networks. This raises, however, several complex research questions on privacy, information security and trust. The study reported here provides motivation and a roadmap for approaching integrated security management solutions in a business network of partners with heterogeneous information and communication technologies (ICT): Systems, platforms, infrastructures as well as security policies. Enterprise architecture (EA) is proposed as a means for comprehensive and coordinated planning and management of corporate ICT and the security infrastructure. The EA approach …
HL7v3 CDA Rel.2 prescription: Localization experience and GP Integration Project
2010
The localization experience for the e-prescription, based on the Health Level Seven Version 3 (HL7v3) Clinical Document Architecture, Release 2 (CDA Rel.2), is presented. As application, we propose a project of General Practitioners Integration with the EHR (Electronic Health Record), implementing the e-prescription, patient summary and other CDA Rel.2 documents. The integration is made possible with HL7v3, the most widely used standard for healthcare information interoperability. The project is in line with the state of the art in the normative referring context for the Italian Healthcare, both at national and regional level (Tuscany Region). Final remarks are drawn, also referring to the …
Uncertainty in information system development: Causes, effects, and coping mechanisms
2020
Information system development (ISD) projects are an ever-growing field of project management (PM) with their unique features, and project failures in ISD are relatively common. In the broader context of PM, uncertainty is a studied, yet mercurial phenomenon. By contrast, uncertainty in ISD projects has received relatively little attention from scholars, and PM literature has not systematically focused on uncertainty in ISD from a viewpoint other than that of project managers. In order to understand uncertainties in ISD projects, we need to first understand the causes behind them, their effects on everyday ISD work, and share coping mechanisms utilized among industry professionals. In the c…
Meanings of communication technology in virtual team meetings : framing technology-related interaction
2018
Communication technology is an essential part of virtual teams in working life. This article presents a qualitative study on the meanings of communication technology in virtual team meetings. The study was conducted by examining frames of technology-related virtual team interaction. Observational data was gathered from six expert team meetings. Technology-related communication episodes (N = 88) were identified from team interaction and then analyzed by means of frame analysis. Four frame categories were found: the practical frame, work frame, user frame, and relational frame. Team members talked about technological properties and functions as well as giving and receiving technological guida…
FCA-based knowledge representation and local generalized linear models to address relevance and diversity in diverse social images
2019
Abstract In social image retrieval, the main goal is to offer a relevant but also diverse result set of images to the user. To address relevance and diversity at the same time, we propose a multi-modal procedure. This approach deals with the diversification problem using a two-step procedure based on the application of Formal Concept Analysis (FCA) to organize the text content of the images, followed by a Hierarchical Agglomerative Clustering (HAC) step to find the topics addressed by the images. FCA detects the latent concepts covered by the images in the result set, organizing them according to these concepts. In the second step, clustering is carried out to group together the ones with a…
Knowledge-driven multi-agent simulation engineering for assessing the effectiveness of disaster management plans
2020
Protecting humans from disasters has been an active mission of governments and experts through the definition of disaster management plans. Defining disaster response strategies is crucial in order to reduce the number of victims and the economic impact. In order to select which response plan is best suited to a specific disaster situation, these plans must be evaluated. However, such evaluation is limited by the high cost of exercises and the specificity of existing simulation models. The approach defended in this thesis combines techniques from Semantic Web and multi-agent simulation to evaluate disaster management response plans. It is composed of four steps : (1) modeling disaster manag…
Minimal Forbidden Factors of Circular Words
2017
Minimal forbidden factors are a useful tool for investigating properties of words and languages. Two factorial languages are distinct if and only if they have different (antifactorial) sets of minimal forbidden factors. There exist algorithms for computing the minimal forbidden factors of a word, as well as of a regular factorial language. Conversely, Crochemore et al.ÃÂ [IPL, 1998] gave an algorithm that, given the trie recognizing a finite antifactorial language M, computes a DFA of the language having M as set of minimal forbidden factors. In the same paper, they showed that the obtained DFA is minimal if the input trie recognizes the minimal forbidden factors of a single word. We gener…
