Synthesis Of Mn3o4-Encapsulated Graphene Sheet Nanocomposites Via A Facile, Fast Microwave Hydrothermal Method And Their Supercapacitive Behaviour, Li Li, Kuok Hau Seng, Zhixin Chen, Hua-Kun Liu, Ivan P. Nevirkovets, Zaiping Guo

Faculty of Engineering and Information Sciences - Papers: Part A

Well-crystallized Mn3O4-anchored reduced graphene oxide (rGO) nanocomposites have been successfully synthesized via a facile, effective, energy-saving, and scalable microwave hydrothermal technique for potential application as supercapacitor material. Integrating these nanostructures resulted in a strong synergistic effect between the two materials, consequently leading to a hybrid composite with higher specific capacitance compared to the bare Mn3O4 nanoparticles. The results from different sorts of characterization indicate that the Mn3O4 particles were deposited and anchored on graphene sheets. The capacitance value of the rGO(31.6%)–Mn3O4 nanocomposite reached 153 F/g, much higher than that of the bare Mn3O4 (87 F/g) at a scan rate of …

Privacy Issues And Solutions In Social Network Sites, Xi Chen, Katina Michael

Associate Professor Katina Michael

The boom of the internet and the explosion of new technologies have brought with them new challenges and thus new connotations of privacy. Clearly, when people deal with e-government and e-business, they do not only need the right to be let alone, but also to be let in secret. Not only do they need freedom of movement, but also to be assured of the secrecy of their information. Solove [6] has critiqued traditional definitions of privacy and argued that they do not address privacy issues created by new online technologies. Austin [7] also asserts: “[w]e do need to sharpen and …

Privacy- The Times They Are A-Changin', M.G. Michael, Katina Michael

Professor Katina Michael

This special section is dedicated to privacy in the information age. Since the rise of mobile social media in particular and the advent of cloud computing few can dispute that the times have changed. Privacy is now understood in context, and within a framework that is completely different to what it once was. The right to be let alone physically seemingly has been replaced by the right to give away as much information as you want virtually. What safeguards can be introduced into such a society? We cannot claim to wish for privacy as a right if we ourselves do …

Wie Verändert Das Internet Die Demokratie?, Ralf Lindner

Ralf Lindner

Obwohl seit dem Aufstieg des Internets zum Massenmedium in den 1990er Jahren Ernüchterung über die Demokratisierungswirkung der neuen Medien eingetreten ist, werden regelmäßig weitreichende Erwartungen über der politische Transformationspotenzial des Internets formuliert. So wird häufig postuliert, dass das Internet demokratische Politik über kurz oder lang fundamental verändern werde, indem universeller Informationszugang ermöglicht, etablierte Machtstrukturen unterminiert und politische Partizipation gesteigert werde. Der Beitrag erörtert zunächst die Hintergründe für populäre Fehlschlüsse, die die Debatte um elektronische Demokratie begleiten. Auf der Grundlage einer kritischen Reflexion mit den ideologisch-normativ imprägnierten Erwartungen an das Internet werden theoretisch wie empirisch robustere Überlegungen zum Beitrag der neuen …

User Taglines: Alternative Presentations Of Expertise And Interest In Social Media, Hemant Purohit, Alex Dow, Omar Alonso, Lei Duan, Kevin Haas

Kno.e.sis Publications

Web applications are increasingly showing recommended users from social media along with some descriptions, an attempt to show relevancy - why they are being shown. For example, Twitter search for a topical keyword shows expert twitterers on the side for 'whom to follow'. Google+ and Facebook also recommend users to follow or add to friend circle. Popular Internet newspaper- The Huffington Post shows Twitter influencers/ experts on the side of an article for authoritative relevant tweets. The state of the art shows user profile bios as summary for Twitter experts, but it has issues with length constraint imposed by user …

Are Twitter Users Equal In Predicting Elections? A Study Of User Groups In Predicting 2012 U.S. Republican Primaries, Lu Chen, Wenbo Wang, Amit P. Sheth

Kno.e.sis Publications

Existing studies on predicting election results are under the assumption that all the users should be treated equally. However, recent work [14] shows that social media users from different groups (e.g., “silent majority” vs. “vocal minority”) have significant differences in the generated content and tweeting behavior. The effect of these differences on predicting election results has not been exploited yet. In this paper, we study the spectrum of Twitter users who participate in the on-line discussion of 2012 U.S. Republican Presidential Primaries, and examine the predictive power of different user groups (e.g., highly engaged users vs. lowly engaged users, right-leaning …

Radio As The Voice Of God: Peace And Tolerance Radio Programming’S Impact On Norms, Daniel P. Aldrich

Daniel P Aldrich

Observers have argued that radio programming can alter norms, especially through hate radio designed to increase animosity between groups. This article tests whether or not radio programming under the countering violent extremism (CVE) policy framework can reduce potential conflict and increase civic engagement and positive views of foreign nations. Data from surveys of more than 1,000 respondents in Mali, Chad, and Niger illuminate the ways in which peace and tolerance programming changed perspectives and altered behavior in statistically significant ways. Results show that individuals exposed to multi-level U.S. government programming were more likely to listen to peace and tolerance radio. …

Social Construction Of Safety In Uas Technology In Concrete Settings: Some Military Cases Studied, Gwendolyn C.H. Bakx, James M. Nyce

Gwendolyn C.H. Bakx

Unmanned aerial systems (UASs) in general and UAS safety in particular have so far received little attention in the science, technology and society (STS) literature. This paper therefore reports on sev- eral (military) cases of this relatively new technology, focusing specifi cally on issues of safety. Quite often, safety of technology is considered the result of a rational process – one of a series of rational, often calculative, linear steps. The paper’s results suggest that establishing safety in military UASs is very much a social process. Approaching (military) UAS safety from this perspective could perhaps be complementary to more analytical …

Exploring The Effectiveness Of Online Instructional Technology In Higher Education: Professors’ Perspective, George Shaw Jr.

Annual Research Symposium of the College of Communication and Information

Technology has drastically changed the landscape of how, when, and where we can access information. As a result of technological advancements, delivery methods for classroom lectures has also change. In higher education, 21st century technology allows professors to deliver lectures face-to-face or online and synchronous or asynchronous within the online education environment. This pilot study interviewed four faculty members and one instructor at a major university in South Carolina in a one-on-one interview session to explore the effectiveness of online instructional technology. Understanding how open source software help professors make online instructional technology more conducive to the learning and knowledge …

Biodiversity Information For Natural Resource Management: Information Needs And Practices In Southern Appalachia, Miriam Davis, Carol Tenopir

Annual Research Symposium of the College of Communication and Information

Introduction

Natural resource managers rely on high quality, current and complete environmental information to make decisions about how resources and landscapes are managed for biodiversity conservation and human use. As such, they represent a unique combination of research scientist, decision maker and practicing professional. In addition, given the applied nature of their work, relating to conservation, resource use and policy, they are frequently required to make timely decisions with real world consequences. However, wading through the vast amounts of currently available scientific and technical knowledge to find needed information can be a challenge. To be useful, this information must be …

"We've got people wearing recording devices on their fingers, in their caps or sunglasses - there are huge legal and ethical implications here."

Demonstration: Dynamic Sensor Registration And Semantic Processing For Ad-Hoc Mobile Environments (Semmob), Pramod Anantharam, Gary Alan Smith, Josh Pschorr, Krishnaprasad Thirunarayan, Amit P. Sheth

Kno.e.sis Publications

SemMOB enables dynamic registration of sensors via mobile devices, search, and near real-time inference over sensor observations in ad-hoc mobile environments (e.g., fire fighting). We demonstrate SemMOB in the context of an emergency response use case that requires automatic and dynamic registrations of sensor devices and annotation of sensor observations, decoding of latitude-longitude information in terms of human sensible names, fusion and abstraction of sensor values using background knowledge, and their visualization using mash-up.

Using Social Influence To Predict Subscriber Churn, Derek Doran, Veena Mendiratta, Chitra Phadke, Dan Kushnir, Huseyin Uzunalioglu

Kno.e.sis Publications

The saturation of mobile phone markets has resulted in rising costs for operators to obtain new customers. These operators thus focus their energies on identifying users that will churn so they can be targeted for retention campaigns. Typical churn prediction algorithms identify churners based on service usage metrics, network performance indicators, and demographic information. Social and peer-influence to churn, however, is usually not considered. In this paper, we describe a new churn prediction algorithm that incorporates the influence churners spread to their social peers. Using data from a major service provider, we show that social influence improves churn prediction and …

Understanding User Triads On Facebook, Derek Doran, Alberta De La Rosa Algarin, Swapna S. Gokhale

Kno.e.sis Publications

Contemporary approaches that analyze user behavior on online social networks only consider interactions among dyads, which are pairs of directly connected users. A large body of sociological work, however, suggests that mutual connections among users can influence their activities, leading to differences between two- and three-way interactions. This paper explores the dynamics of triads among Facebook users based on the wall posts from the New Orleans regional network. Initially, each connection is categorized as a close friendship or an acquiantance, contingent on the number of wall posts exchanged. Subsequently, the impact of different types of connections comprising triads is examined …

How I Would Like Semantic Web To Be, For My Children., Raghava Mutharaju

Kno.e.sis Publications

Semantic Web, since its inception, has gone through lot of developments in its relatively nascent existence; right from people's perception, to the standards and to its adoption by the industry and more importantly by the scientific community. This impressive growth only seems to increase. In this paper, we project this growth to the next 10 years and highlight some of the facets on which Semantic Web could have a major impact on. We also present the challenges that Semantic Web and its community has to deal with in order to get there.

Do Students Using Electronic Books Display Different Reading Comprehension And Motivation Levels Than Students Using Traditional Print Books?, Casey Wells

Doctoral Dissertations and Projects

The effect of electronic books on the reading comprehension of middle and high school students was examined using an experimental posttest-only control-group design. A convenience sample of 140 randomly assigned middle and high school English students at an independent school in eastern North Carolina participated. Half of the students used passages from text read on tablets while half utilized traditional print text passages. Data was collected during one class period in which the reading comprehension section of the Gates-MacGinitie Reading Tests®, a 35 minute test containing 48 questions, was administered. Reading comprehension data was analyzed using an independent t-test. The …

An Efficient Bit Vector Approach To Semantics-Based Machine Perception In Resource-Constrained Devices, Cory Andrew Henson, Krishnaprasad Thirunarayan, Amit P. Sheth

Kno.e.sis Publications

The primary challenge of machine perception is to define efficient computational methods to derive high-level knowledge from low-level sensor observation data. Emerging solutions are using ontologies for expressive representation of concepts in the domain of sensing and perception, which enable advanced integration and interpretation of heterogeneous sensor data. The computational complexity of OWL, however, seriously limits its applicability and use within resource-constrained environments, such as mobile devices. To overcome this issue, we employ OWL to formally define the inference tasks needed for machine perception – explanation and discrimination – and then provide efficient algorithms for these tasks, using bit-vector encodings …

Indian Millennials: Are Microchip Implants A More Secure Technology For Identification And Access Control?, Christine Perakslis, Katina Michael

Associate Professor Katina Michael

This mixed methods study with a sequential explanatory strategy explored qualitatively the statistically significant quantitative findings relative to Indian respondents’ perceptions about RFID (radio frequency identification) transponders implanted into the human body. In the first analysis phase of the study, there was a significant chi-square analysis reported (χ2 = 56.64, df = 3, p = .000) relative to the perception of small business owners (N = 453) that implanted chips are a more secure form of identification and/or access control in organizations and the respondents’ country of residence. Countries under study included Australia, India, the UK and US. The country …

Breve Perspectiva Crítica Sobre El Gobierno Abierto Y El Open Data, Lucas Jolías, Alejandro Prince

Lucas Jolías

Las ciberculturas y sus apóstoles aportan cada tanto tiempo y de forma incremental, nuevos conceptos o memes, es decir, unidades teóricas de información cultural transmisibles entre individuos, mentes o generaciones. Algunos de estos conceptos son vacíos, otros son comerciales, varios son sólo nuevos nombres de viejas ideas, pero todos de alguna manera connotan los cambios o tendencias de lo que en forma general podemos denominar la Sociedad del Conocimiento. Algunos de estos conceptos mueren a poco de nacer, otros cobran fuerza y vida propia (como la “web 2.0”), suman fans o detractores, y hasta se institucionalizan. De estos, y entre …

Presupuesto Participativo En Argentina: Análisis De Su Evolución Y Estudio De Caso, Lucas Jolías, Alejandro Prince, Ana Doria

Lucas Jolías

Las sociedades de los países occidentales con sistemas democráticos representativos están tendiendo, en los últimos tiempos, a implementar políticas públicas de Democracia Directa y Semi-Directa, a través de acciones y políticas participativas con la intervención de los ciudadanos en las decisiones de gobierno. El Presupuesto Participativo se convirtió en uno de los procesos más consolidados y genuinos de este tipo de ejercicio de democracia. En la Argentina, desde comienzos de siglo, algunos municipios han comenzado a implementar esta práctica, sin embargo, son al día de hoy experiencias esporádicas y no existe una marco común de acción que las agrupe.
