The authors consider applications where data is acquired in real-time, and thus data mining is performed on live streams of data rather than on stored databases. One challenge in supporting such applications is that sensor node power is a precious resource that needs to be managed as such. To conserve energy in the sensor field, the authors propose and evaluate several approaches to acquiring, and then caching data in a sensor field data server. The authors show that for true real-time applications, for which response time dictates data quality, policies that emulate cache hits by computing and returning approximate values for sensor data yield a simultaneous quality improvement and cost saving. This "win-win" is because when data acquisition response time is sufficiently important, the decrease in resource consumption and increase in data quality achieved by using approximate values outweighs the negative impact on data accuracy due to the approximation. In contrast, when data accuracy drives quality, a linear trade-off between resource consumption and data accuracy emerges. The authors then identify caching and lookup policies for which the sensor field query rate is bounded when servicing an arbitrary workload of user queries. This upper bound is achieved by having multiple user queries share the cost of a sensor field query. Finally, the authors discuss the challenges facing sensor network data mining applications in terms of data collection, warehousing, and mining techniques.

We show using data from the OECD and the International Telecommunication Union (ITU) that this new digital divide is a global problem that can be observed in both developed and developing countries. To bridge the global broadband divide, organizations and individuals must collaborate to provide broadband access to a converged high-speed Internet for both rich and poor citizens worldwide. Most previous research has focused on the broadband divide in developed countries and the role of several factors in bridging this divide, including competition to provide broadband service to businesses and consumers. We argue that addressing this global problem is an ethical imperative that requires bridging the perspectives of multiple stakeholders and applying their collective resources, power and will. We develop a comprehensive framework, using stakeholder theory, which identifies the global stakeholders as well as the roles and responsibilities that these stakeholders must assume to balance their self-interest with serving the common good. Our framework also highlights relationships between key stakeholders, namely governments and their citizens, businesses in the information and communication technology (ICT) industries, and other organizations. Using this framework and recent ITU and World Bank data, we make four important observations that can guide governments and other stakeholders in bridging the broadband divide in pursuit of the common good: (1) A national authority that regulates the activities of the many stakeholders within a country's telecommunications sector has a positive impact on broadband adoption. (2) A shared financial investment in the physical infrastructure and human capital required to deploy and operate broadband networks also helps increase broadband diffusion. (3) An independent regulatory authority and shared financial investment are at least as important as telecommunications service provider competition in expanding broadband Internet access. And, (4) service provider competition has a greater impact on broadband affordability than it does on broadband diffusion.

In response to this problem, the World Bank has advocated a “mobile first” strategy for developing countries. Unfortunately, there is little understanding of what determines mobile broadband adoption or diffusion in developing countries. In this paper, we begin to address this problem by exploring to what extent policy, regulation, government, and governance affect mobile broadband diffusion in the developing world. Our results show that when controlling for distribution and level of income, there is greater mobile diffusion in developing (i.e., non-OECD) countries that encourage competition in their telecommunication industries and practice sound governance in their public sector. Although governance is an important determinant of mobile broadband diffusion, we find no evidence that political structure (i.e., the level ...

Past research, however, highlights differences in their availability in developed and developing countries. This phenomenon is known as the digital divide (Norris, 2001; Warschauer, 2004, Pick and Sarkar, 2015). Of the approximately 200 nations for which digital divide data are reported by the International Telecommunications Union (ITU), more than 135 of these have some mobile broadband Internet access (ITU, 2013). The troubling news in these recent data, however, is that in 25 of these countries the annual cost of mobile broadband service is more than a month’s pay (i.e., more than 8.33% of the per capita income). Since mobile broadband technologies are becoming a critical means of communication and Internet access (World Bank, 2012), understanding the affordability and adoption of these technologies is an emerging area of research (García-Murillo and Rendón, 2009; Grub...

The architecture of Apache has been a primary driver of this success. To understand what has made Apache thrive, and to learn from its success, we turn to lessons gleaned from physical architecture. Christopher Alexander distilled architectural quality into fifteen properties, the combination of which determines whether the architecture will exhibit wholeness, or life. Waguespack has applied Alexander's theory to articulate fifteen corresponding properties of modeling and information systems that determine whether an information system will have sufficient functionality and strength to thrive. We first explain Apache's success over time through the application of these properties. We then explore how organizations can emulate this success in their own information systems by managing the portfolio of properties. Linking information systems properties to desirable business outcomes to create a synergy between design goals and business requirements is critical to success. For a system to serve the needs of a business, its design and implementation should not only accommodate but facilitate change. We argue that facilitating change amplifies, not obviates, the need for great architecture. Applying the lessons from physical architecture to enable systems to thrive thus improves both system agility and business agility.

Our research examines two distinct but related measures of e-government effectiveness, namely the online service index and the e-participation index, both reported in the 2010 e-government survey conducted by United Nations. We analyze the impact of political structure, administrative culture and policy initiatives on both indices in approximately 160 countries. Our multiple regression analysis shows that when controlling for measures of economic and educational development, there is greater egovernment capability in countries that have an administrative culture of sound governance and policies that promote the development and diffusion of information and communication technologies. These results hold in nations that are more democratic, even though political freedom (i.e., press freedom and civil liberties) appears to have a negative impact on egovernment. These results suggest that the path to egovernment leverages different strategies depending on a nation's political structure, and that countries in which there is less political freedom may be utilizing egovernment to maintain the status quo.

The research question posed in this study is: Do national policy initiatives, regulatory measures, or governance practices increase a nation's mobile broadband diffusion? There is little research that has analyzed the impact of these factors on bridging the mobile broadband digital divide in highly developed or developing countries. Our empirical findings show that when controlling for measures of wealth, education, and other factors, there is greater mobile broadband diffusion in countries that encourage competition in their broader telecommunications sector and practice sound regulation. In countries where open competition allows alternative ICTs to compete with each other, the presence of more expensive alternative telecommunication services also increases mobile broadband diffusion. Although theory suggests that sound regulation and sound governance should both positively affect mobile diffusion, we observe where this theory breaks down in practice. Specifically, outliers in our data set show that a few countries have achieved high levels of mobile broadband adoption even though they face significant problems with corruption in their government.

For this purpose, a cross-national multiple regression analysis of non-OECD countries is used. The results revealed that when controlling for wealth, education and other factors, competition to provide mobile services, financial investment in ICTs, and income inequality are all important variables for determining mobile broadband affordability. Findings suggest that service providers and other stakeholders are still recouping the cost of deploying the infrastructure necessary to provide mobile services, and have not yet achieved the economies of scale required for the price of mobile broadband to begin to fall, at least in the developing world. This paper provides contributions to academia, industry, and policymakers.

This is of special concern in the cloud, which provides access to large numbers of computers. We examine the use of ARM-based clustersforlow-power,highperformancecomputing.Thiswork examinestwolikelyuse-modes:(i)astandarddedicatedcluster; and (ii) a cluster of pre-configured virtual machines in the cloud. A 40-node department-level cluster based on an ARM Cortex-A9 is compared against a similar cluster based on an Intel Core 2 Duo, in contrast to a recent similar study on just a 4-node cluster. For the NAS benchmarks on 32node clusters, ARM was found to have a power efficiency ranging from 1.3 to 6.2 times greater than that of Intel. This is despite Intel’s approximately five times greater performance. The particular efficiency ratio depends primarily on the size of the working set relative to L2 cache. In addition to energyefficient computing, this study also emphasizes fau...

We classify Twitter users as Liberal or Conservative to better understand how the two groups use social media during a major national political election. Using tweet sentiment, we assess how the Twittersphere felt about in-group party versus outgroup party candidates. When we further break these findings down based on the candidates' gender, we find that male senatorial candidates were talked about more positively than female candidates. We also find that Conservatives talked more positively about female Republican candidates than they did about Republican male candidates. Female candidates of the out-group party were talked about the least favorably of all candidates. Conservative tweeters exhibit the most positive level of in-group party sentiment and the most negative level of out-group party sentiment. We therefore attribute the most intense affective polarization to this ideological group.

We posit co-creation as a way to overcome this limitation that engages reflective design practice fostering a shared understanding of value among the designers/developers, users, analysts and others. Thus, co-creation is an essential ingredient for design satisfaction in many design endeavors. We proffer a theoretical foundation for envisioning design success as an artefact that realizes co-created conceptual metaphors compositing the objective and subjective qualities shaping the stakeholders' appreciative systems. This paper positions and advocates for a critical perspective on designer transcendence where design choices and actions are centered on a shared, but evolving, composite understanding of value and quality-satisfaction. Successful co-creative design emancipates users from concern for unnecessary technically rational aspects of artefact design. Further we propose a framework, grounded in semiotics, to hone and revitalize designer transcendence with a design emphasis on efficient and ideally frictionless interfaces-conceptual metaphors-to reduce asymmetry among stakeholder concerns. 1.4 Co-created Design and Design Science Research We examine co-created design as currently conceptualized in the design science research (DSR) literature and identify opportunities to better conceptualize co

This paper argues that a profile of “T-shaped” skills, which is known to be desirable in many consulting and design professions, is being reflected in the latest manifestations of cybersecurity curriculum design and accreditation. A model of learning that yields “T-shaped” professionals combines the ability to apply knowledge across domains (breadth) with the ability to apply functional and disciplinary skills (depth).

This paper describes a simulation game offered to students in a first-year computing concepts course to introduce both models of application development. Students work in development teams to design, build, and test paper airplanes following both waterfall and agile principles to experience the roles, processes, and challenges of each. Participants track their team’s progress throughout the activity, so they can draw conclusions about the benefits and challenges of each approach. Survey results indicate that students learned the various roles and approaches of both methods through this experience.

We show using data from the OECD and the International Telecommunication Union (ITU) that this new digital divide is a global problem that can be observed in both developed and developing countries. To bridge the global broadband divide, organizations and individuals must collaborate to provide broadband access to a converged high-speed Internet for both rich and poor citizens worldwide. Most previous research has focused on the broadband divide in developed countries and the role of several factors in bridging this divide, including competition to provide broadband service to businesses and consumers. We argue that addressing this global problem is an ethical imperative that requires bridging the perspectives of multiple stakeholders and applying their collective resources, power and will. We develop a comprehensive framework, using stakeholder theory, which identifies the global stakeholders as well as the roles and responsibilities that these stakeholders must assume to balance their self-interest with serving the common good. Our framework also highlights relationships between key stakeholders, namely governments and their citizens, businesses in the information and communication technology (ICT) industries, and other organizations. Using this framework and recent ITU and World Bank data, we make four important observations that can guide governments and other stakeholders in bridging the broadband divide in pursuit of the common good: (1) A national authority that regulates the activities of the many stakeholders within a country's telecommunications sector has a positive impact on broadband adoption. (2) A shared financial investment in the physical infrastructure and human capital required to deploy and operate broadband networks also helps increase broadband diffusion. (3) An independent regulatory authority and shared financial investment are at least as important as telecommunications service provider competition in expanding broadband Internet access.

Our multiple regression analysis shows that factors that determine broadband diffusion in technologically developed countries do not necessarily have the same impact in less developed countries. We show that in technological developed countries, there is greater broadband diffusion in countries that make a higher financial investment in information and communication technologies and have effective regulatory and administrative practices at the national level. While these results hold in technologically developing nations, a competitive telecommunications sector also lead to greater broadband diffusion but the presence of a national telecommunications regulatory authority has a negative impact. These results suggest that the path to widespread availability and use of broadband requires different strategies depending on a nation’s level of technological development.
