    Get PDF
    The economic-driven evaluation of information technology (IT) has become an important instrument in the management of IT projects. Numerous approaches have been developed to quantify the costs of an IT investment and its assumed profit, to evaluate its impact on business process performance, and to analyze the role of IT regarding the achievement of enterprise objectives. This paper discusses approaches for evaluating IT from an economic-driven perspective. Our comparison is based on a framework distinguishing between classification criteria and evaluation criteria. The former allow for the categorization of evaluation approaches based on their similarities and differences. The latter, by contrast, represent attributes that allow to evaluate the discussed approaches. Finally, we give an example of a typical economic-driven IT evaluation

    Two Decades after the birth of the World Wide Web, more than two billion people around the world are Internet users. The digital landscape is littered with hints that the affordances of digital communications are being leveraged to transform life in profound and important ways. The reach and influence of digitally mediated activity grow by the day and touch upon all aspects of life, from health, education, and commerce to religion and governance. This trend demands that we seek answers to the biggest questions about how digitally mediated communication changes society and the role of different policies in helping or hindering the beneficial aspects of these changes. Yet despite the profusion of data the digital age has brought upon us—we now have access to a flood of information about the movements, relationships, purchasing decisions, interests, and intimate thoughts of people around the world—the distance between the great questions of the digital age and our understanding of the impact of digital communications on society remains large. A number of ongoing policy questions have emerged that beg for better empirical data and analyses upon which to base wider and more insightful perspectives on the mechanics of social, economic, and political life online. This paper seeks to describe the conceptual and practical impediments to measuring and understanding digital activity and highlights a sample of the many efforts to fill the gap between our incomplete understanding of digital life and the formidable policy questions related to developing a vibrant and healthy Internet that serves the public interest and contributes to human wellbeing. Our primary focus is on efforts to measure Internet activity, as we believe obtaining robust, accurate data is a necessary and valuable first step that will lead us closer to answering the vitally important questions of the digital realm. Even this step is challenging: the Internet is difficult to measure and monitor, and there is no simple aggregate measure of Internet activity—no GDP, no HDI. In the following section we present a framework for assessing efforts to document digital activity. The next three sections offer a summary and description of many of the ongoing projects that document digital activity, with two final sections devoted to discussion and conclusions

    CRITICAL URBAN PEDAGOGY: Convites as Sites of Southern Urbanism, Solidarity Construction and Urban Learning

    Get PDF
    Learning from the pedagogical potentials of Southern city-making practices is imperative to foster emancipatory urban learning settings. However, the ways in which urban learning spaces beyond professional settings operate and how Southern urbanism practices constitute new critical pedagogies are poorly understood. We draw on research about urban learning on ‘slum upgrading’ in the city of Medellín (Colombia), a benchmark in dealing in tandem with informality and urban violence, to analyze the pedagogical potentials of convites. Convites are an essential sociospatial mechanism of self-build settlements rooted in solidarity networks that initiate collective action and celebration through public cooking. This practice of makeshift community kitchens led by women became the backbone of the response to the scarcities caused by the pandemic in self-built neighborhoods in Latin America. In this article we ask what Southern urbanism and critical pedagogy can learn from convites. We then analyze the ways in which convites combine community kitchens as learning environments, the use of collective storytelling as a learning device, and collective action through networked solidarities. We argue that critical urban pedagogy is a situated pedagogy derived from everyday relations of place, body and materiality infused by memory and articulated by storytelling

    Get PDF
    This working paper has been prepared as part of the East-West Center's research project on Globalization of Knowledge Work: Why is Chip Design Moving to Asia. In this paper, Dieter assesses what we know about the limits to modularity and their impact on firm organization and industry structure. He focuses on evidence form chip design, drawing on interview on 2002 and 2003 with a sample of 60 companies and 15 research institutions that are involved in chip design in the US, Taiwan, Korea, China and Malaysia. It is summarized "stylized" propositions of the modularity literature that are well-established, as well as predictions that are controversial. In addition, important limits to modularity and relevant management responses were reviewed.

    In dieser Dissertation untersuche ich die Forschungswege von sechs Wissenschaftlern, die in verschiedenen Disziplinen und Institutionen in den Vereinigten Staaten und in der Tschechischen Republik arbeiten. Um dies zu tun, verwende ich sogenannte „multi-sited“ ethnographisch-methodische Strategien (d.h. Strategien, die Anthropologen verwenden, um Kulturen an zwei oder mehr geografischen Standorten zu vergleichen), mit dem Ziel, informationsbezogene Verhaltensweisen dieser Wissenschaftler im global vernetzten akademischen Umfeld zu untersuchen, englisch abgekürzt „GNAE“, ein Begriff, der sich speziell auf die komplexe Bricolage von Netzwerkinfrastrukturen, Online-Informationsressourcen und Tools bezieht, die Wissenschaftler heutzutage nutzen, d.h. die weltweite akademische e-IS, oder akademische Infrastruktur (Edwards et al. 2013). Die zentrale Forschungsfrage (RQ1), die in dieser Dissertation beantwortet wird, ist: Gibt es, gemäß der multi-sited ethnographischen Analyse der beteiligten Wissenschaftler in dieser Studie—Personen, die Forschung in verschiedenen Disziplinen und Institutionen sowie an unterschiedlichen Standorten betreiben—Hinweise darauf, dass ein signifikanter Anteil der nicht-institutionellen/informellen informationsbezogenen Forschung über Mechanismen im GNAE, die nicht von Bibliotheken unterstützt werden, betrieben wird, sowie (RQ2): Was für Muster sind vorhanden und wie beziehen sie sich auf informationswissenschaftliche und andere sozialwissenschaftliche Theorien? Und drittens (RQ3): Haben die Resultate praxisnahe Bedeutungen für die Entwicklung von Dienstleistungen in wissenschaftlichen Bibliotheken? Ethnographische Strategien sind bisher noch nicht in der Informationswissenschaft (IS) eingesetzt worden, um Fragen dieser Art zu untersuchen. Die Ergebnisse zeigen, dass eine informelle Informationsexploration nur bei zwei Wissenschaftlern, die mit offenen Daten und Tools einer verteilten Computing-Infrastruktur arbeiten, zu finden ist.In this dissertation I examine the pathways of information exploration and discovery of six scientists working in different research disciplines affiliated with several academic institutions in the United States and in the Czech Republic. To do so, I utilize multi-sited ethnographic methodological strategies (i.e., strategies developed by anthropologists to compare cultures across two or more geographic locations) to examine the information-related behaviors of these scholars within the global networked academic environment (GNAE), a term which specifically refers to the complex bricolage of network infrastructures, online information resources, and tools scholars use to perform their research today (i.e., the worldwide academic e-IS, or academic infrastructure [Edwards et al. 2013]). The central research question (RQ1) to be answered in this dissertation: According to the multi-sited ethnographic analysis of scientists participating in this study—individuals conducting research in various disciplines at different institutions in several geographical locations—is there evidence indicating a significant allotment of non-institutional/informal information-related exploration and discovery occurring beyond official library-supported mechanisms in the GNAE?, and—part two (RQ2) of the central research question—What (if any) patterns are exhibited and how do these patterns relate to information science (IS) and other social science theories? Both RQ1 and RQ2 are exploratory. I additionally ask (RQ3): What might all this mean in the applied sense? by showing examples of services piloted during the research process in response to my observations in the field. Multi-sited ethnographic strategies have not yet been employed in IS, as of the date of publication of this thesis, to examine such questions. Results indicate informal information exploration occurring only with two scientists who use of open data and tools on a distributed computing infrastructure

    What E-Learning Providers and End Users Should Do Respectively before Initiating Such a Learning Project

    Get PDF
    As an E-learning provider, before offering such a product it needs to carry out a thorough analysis in order to understand the customers and trends, and evaluate external environmental forces which include market demand, political and legal forces, social and ethical influences, technology and competition. Through conducting a thorough analysis, a clear strategy can be developed that identifies which customers the e-learning provider is to target and where their product or services will be best positioned. To some extent providers are forced continually to forecast, monitor and assess this environment and to adapt e-learning products or services accordingly before offering learning products. To implement e-learning project successfully, the end users need to understand what e-learning is good at and not so good at. When this basic analysis is complete, one can go into the organization looking for specific learning needs that could be met with e-learning. The advantage of starting by doing is that users will find out where they need help, and where they can manage perfectly well on their own. For any company, the returns must be considered carefully before undertaking such a program. In this article, it also explores the benefits of e-learning investments with a particular focus upon measuring the value of delivering an enterprise e-learning initiative. In addition to the many measurable returns, the paper offers a number of formulas for calculating the ROI and justifying the cost. The article concludes with guidelines detailing the implementation of e-learning initiative

    The Piratical Ethos: Textual Activity and Intellectual Property in Digital Environments

    Get PDF
    The Piratical Ethos: Textual Activity and Intellectual Property in Digital Environments examines the definition, function, and application of intellectual property in contexts of electronically mediated social production. With a focus on immaterial production - or the forms of coordinated social activity employed to produce knowledge and information in the networked information economy - this project ultimately aims to demonstrate how current intellectual property paradigms must be rearticulated for an age of digital (re)production. By considering the themes of Piracy , Intellectual Property , and Distributed Social Production this dissertation provides an overview of the current state of peer production and intellectual property in the Humanities and Writing Studies. Next, this project develops and implements a communicational-mediational research methodology to theorize how both discursive and material data lend themselves to a more nuanced understanding of the ways that technologies of communication and coordination effect attitudes toward intellectual property. After establishing both a methodology and an interdisciplinary grounding for the themes of the work, this dissertation presents a grounded theoretic analysis of piratical discourse to reveal what I call the piratical ethos , or the guiding attitudes of individuals actively contesting intellectual property in piratical acts of distributed social production. Congruently, this work also investigates the material dynamics of piratical activity by analyzing the cultural-historical activity systems wherein piratical subjectivity emerges, emphasizing the agenic capacity of interfacial technologies at the scales of user and system. Exploring the attitudes of piratical subjects and the technological genres that mediate piratical activity, I contend that the conclusions drawn from The Piratical Ethos can assist Writing Studies researchers with developing novel methodologies to study the intersections of intellectual property and distributed social production in digital worlds

    Sustainability Benefits Analysis of CyberManufacturing Systems

    Get PDF
    Confronted with growing sustainability awareness, mounting environmental pressure, meeting modern customers’ demand and the need to develop stronger market competitiveness, the manufacturing industry is striving to address sustainability-related issues in manufacturing. A new manufacturing system called CyberManufacturing System (CMS) has a great potential in addressing sustainability issues by handling manufacturing tasks differently and better than traditional manufacturing systems. CMS is an advanced manufacturing system where physical components are fully integrated and seamlessly networked with computational processes. The recent developments in Internet of Things, Cloud Computing, Fog Computing, Service-Oriented Technologies, etc., all contribute to the development of CMS. Under the context of this new manufacturing paradigm, every manufacturing resource or capability is digitized, registered and shared with all the networked users and stakeholders directly or through the Internet. CMS infrastructure enables intelligent behaviors of manufacturing components and systems such as self-monitoring, self-awareness, self-prediction, self-optimization, self-configuration, self-scalability, self-remediating and self-reusing. Sustainability benefits of CMS are generally mentioned in the existing researches. However, the existing sustainability studies of CMS focus a narrow scope of CMS (e.g., standalone machines and specific industrial domains) or partial aspects of sustainability analysis (e.g., solely from energy consumption or material consumption perspectives), and thus no research has comprehensively addressed the sustainability analysis of CMS. The proposed research intends to address these gaps by developing a comprehensive definition, architecture, functionality study of CMS for sustainability benefits analysis. A sustainability assessment framework based on Distance-to-Target methodology is developed to comprehensively and objectively evaluate manufacturing systems’ sustainability performance. Three practical cases are captured as examples for instantiating all CMS functions and analyzing the advancements of CMS in addressing concrete sustainability issues. As a result, CMS has proven to deliver substantial sustainability benefits in terms of (i) the increment of productivity, production quality, profitability & facility utilization and (ii) the reduction in Working-In-Process (WIP) inventory level & material consumption compared with the alternative traditional manufacturing system paradigms
