Social Media Perceptions And Usage By Generation Y And Relevant Marketing Implications, Irene J. Dickey, William F. Lewis 2010 University of Dayton

Social Media Perceptions And Usage By Generation Y And Relevant Marketing Implications, Irene J. Dickey, William F. Lewis

Management and Marketing Faculty Publications

One of the most common ways in which Internet users connect and network with each other is through "social media." Social media is the content that is provided and maintained by the user on a website. It is clear that social media such as Facebook and LinkedIn are becoming increasingly pervasive in the lives of students, professionals and consumers. A literature review, as well as the results from our survey, reveals that not only have social networks evolved rapidly during the last few years, but so too have consumers’ behaviors. Subsequently, marketing strategies and tactics, and the potential for practitioners ...


Semantics Centric Solutions For Application And Data Portability In Cloud Computing, Ajith Harshana Ranabahu, Amit P. Sheth 2010 Wright State University - Main Campus

Semantics Centric Solutions For Application And Data Portability In Cloud Computing, Ajith Harshana Ranabahu, Amit P. Sheth

Kno.e.sis Publications

Cloud computing has become one of the key considerations both in academia and industry. Cheap, seemingly unlimited computing resources that can be allocated almost instantaneously and pay-as-you-go pricing schemes are some of the reasons for the success of Cloud computing. The Cloud computing landscape, however, is plagued by many issues hindering adoption. One such issue is vendor lock-in, forcing the Cloud users to adhere to one service provider in terms of data and application logic. Semantic Web has been an important research area that has seen significant attention from both academic and industrial researchers. One key property of Semantic Web ...


From Questions To Effective Answers: On The Utility Of Knowledge-Driven Querying Systems For Life Sciences Data, Amir H. Asiaee, Prashant Doshi, Todd Minning, Satya S. Sahoo, Priti Parikh, Amit P. Sheth, Rick L. Tarleton 2010 Wright State University - Main Campus

From Questions To Effective Answers: On The Utility Of Knowledge-Driven Querying Systems For Life Sciences Data, Amir H. Asiaee, Prashant Doshi, Todd Minning, Satya S. Sahoo, Priti Parikh, Amit P. Sheth, Rick L. Tarleton

Kno.e.sis Publications

We compare two distinct approaches for querying data in the context of the life sciences. The first approach utilizes conventional databases to store the data and intuitive form-based interfaces to facilitate easy querying of the data. These interfaces could be seen as implementing a set of 'pre-canned' queries commonly used by the life science researchers that we study. The second approach is based on semantic Web technologies and is knowledge (model) driven. It utilizes a large OWL ontology and same datasets as before but associated as RDF instances of the ontology concepts. An intuitive interface is provided that allows the ...

The Resource Description Framework (RDF) format is being used by a large number of scientific applications to store and disseminate their datasets. The provenance information, describing the source or lineage of the datasets, is playing an increasingly significant role in ensuring data quality, computing trust value of the datasets, and ranking query results. Current provenance tracking approaches using the RDF reification vocabulary suffer from a number of known issues, including lack of formal semantics, use of blank nodes, and application-dependent interpretation of reified RDF triples. In this paper, we introduce a new approach called Provenance Context Entity (PaCE) that uses ...


Scale: A Scalable Framework For Efficiently Clustering Transactional Data, Hua Yan, Keke Chen, Ling Liu, Zhang Yi 2010 Wright State University - Main Campus

Scale: A Scalable Framework For Efficiently Clustering Transactional Data, Hua Yan, Keke Chen, Ling Liu, Zhang Yi

Kno.e.sis Publications

This paper presents SCALE, a fully automated transactional clustering framework. The SCALE design highlights three unique features. First, we introduce the concept of Weighted Coverage Density as a categorical similarity measure for efficient clustering of transactional datasets. The concept of weighted coverage density is intuitive and it allows the weight of each item in a cluster to be changed dynamically according to the occurrences of items. Second, we develop the weighted coverage density measure based clustering algorithm, a fast, memory-efficient, and scalable clustering algorithm for analyzing transactional data. Third, we introduce two clustering validation metrics and show that these domain ...

Genomic sequencing projects are an abundant source of information for biological studies ranging from the molecular to the ecological in scale; however, much of the information present may yet be hidden from casual analysis. One such information domain, trends in codon usage, can provide a wealth of information about an organism's genes and their expression. Degeneracy in the genetic code allows more than one triplet codon to code for the same amino acid, and usage of these codons is often biased such that one or more of these synonymous codons is preferred. Detection of this bias is an important ...

The LOD cloud is gathering a lot of momentum, with the number of contributors growing manifold. Many prominent data providers have submitted and linked their data to other dataset with the help of manual mappings. The potential of the LOD cloud is enormous ranging from challenging AI issues such as open domain question answering to automated knowledge discovery. We believe that there is not enough technology support available to effectively query the LOD cloud. To this effect, we present a system called Linked Open Data SPARQL Querying System (LOQUS), which automatically maps users queries written in terms of a conceptual ...


A Qualitative Examination Of Topical Tweet And Retweet Practices, Meenakshi Nagarajan, Hemant Purohit, Amit P. Sheth 2010 Wright State University - Main Campus

A Qualitative Examination Of Topical Tweet And Retweet Practices, Meenakshi Nagarajan, Hemant Purohit, Amit P. Sheth

Kno.e.sis Publications

This work contributes to the study of retweet behavior on Twitter surrounding real-world events. We analyze over a million tweets pertaining to three events, present general tweet properties in such topical datasets and qualitatively analyze the properties of the retweet behavior surrounding the most tweeted/viral content pieces. Findings include a clear relationship between sparse/dense retweet patterns and the content and type of a tweet itself; suggesting the need to study content properties in link-based diffusion models.


Linked Open Social Signals, Pablo N. Mendes, Alexandre Passant, Pavan Kapanipathi, Amit P. Sheth 2010 Wright State University - Main Campus

Linked Open Social Signals, Pablo N. Mendes, Alexandre Passant, Pavan Kapanipathi, Amit P. Sheth

Kno.e.sis Publications

In this paper we discuss the collection, semantic annotation and analysis of real-time social signals from micro-blogging data. We focus on users interested in analyzing social signals collectively for sensemaking. Our proposal enables flexibility in selecting subsets for analysis, alleviating information overload. We define an architecture that is based on state-of-the-art Semantic Web technologies and a distributed publish subscribe protocol for real time communication. In addition, we discuss our method and application in a scenario related to the health care reform in the United States.


Creating Contagious: How Social Networks And Item Characteristics Combine To Drive Persistent Social Epidemics, Andrew T. Stephen, Jonah A. Berger 2010 University of Pennsylvania

Creating Contagious: How Social Networks And Item Characteristics Combine To Drive Persistent Social Epidemics, Andrew T. Stephen, Jonah A. Berger

Marketing Papers

Why do certain cultural items capture persistent collective interest while others languish? This research integrates psychological and sociological perspectives to provide deeper insight into social epidemics. First, we develop a psychologically plausible individuallevel model of social transmission behavior. We then situate this model in a social network and perform a series of simulations where we vary different item- and networkrelated characteristics in an experimental setting. The results (1) demonstrate how item and network characteristics combine to drive persistent collective enthusiasm and (2) shed light on the underlying mechanisms through which such social epidemics occur. Interest in most items or products ...


Implementing And Evaluating A 'Next Generation Learning Space': A Pilot Study, Gail Wilson, Marcus Randall 2010 Southern Cross University

Implementing And Evaluating A 'Next Generation Learning Space': A Pilot Study, Gail Wilson, Marcus Randall

Centre for Teaching and Learning

A dramatic, pedagogical shift has occurred in recent years in educational environments in higher education, supported largely by the use of ubiquitous technologies. Increasingly, emphasis is being placed on the design of new learning spaces, often referred to as “Next Generation Learning Spaces” and their impact on pedagogy. The idea of “classroom” now incorporates the use of both physical and virtual space. This change has meant a greater focus on the design and use of flexible learning spaces, more use of blended learning approaches and more personalised, individualised learning opportunities for students. While many such classrooms have been built and ...


Applying The “Contextual Integrity” Model Of Privacy To Personal Blogs In The Blogoshere, Frances Grodzinsky, Herman T. Tavani 2010 Sacred Heart University

Applying The “Contextual Integrity” Model Of Privacy To Personal Blogs In The Blogoshere, Frances Grodzinsky, Herman T. Tavani

School of Computer Science & Engineering Faculty Publications

In this paper, we analyze some controversial aspects of blogging and the blogosphere from the perspective of privacy. In particular, we focus on Helen Nissenbaum’s theory of privacy as “contextual integrity” and apply it to personal blogs, in general, and the case of the “Washingtonienne” blogger, in particular. We examine the question of whether personal blogs that are not password protected can be considered “normatively private contexts” according to Nissenbaum’s principles of privacy. We argue that they cannot. Using Nissenbaum’s original model, we conclude that privacy expectations for those who disclose personal information in such blogs are ...

Acceptance, Communication Mode And Use Of Audio Computer- Assisted Self Interview Using Touchscreen To Identify Risk Factors Among Pregnant Minority Women, Jutta S. Thornberry, Kennan B. Murray, M. Nabil El-Khorazaty, Michele Kiely

Publications and Research

This paper evaluates the acceptability, communication mode and use of audio computer-assisted self-interview (A-CASI) among minority pregnant women receiving prenatal care in six Washington, DC sites. A total of 2,913 women were screened for demographic eligibility (18+ years old,gestation, Black/African-American or Hispanic) and risk (smoking, environmental tobacco smoke exposure, depression, intimate partner violence). Questions were displayed on touch screen laptop monitors and heard through earphones. The mean length of time to complete the screener was almost 6 minutes.

A-CASI experience, which included difficulty in using the computer, acceptability (enjoyment), and preferred communication mode, was compared across sites ...

Facebook Usage Predicted By Sense Of Community And 'Loneliness', Alison Bagworth 2010 Edith Cowan University

Facebook Usage Predicted By Sense Of Community And 'Loneliness', Alison Bagworth

Theses : Honours

Facebook Usage Predicted by Sense of Community and 'loneliness' Face book is one of a growing number of social networking sites (SNSs) that are currently being used by young adults to compliment face-to-face interactions. The use of these sites raises questions in relation to how their function may be compared to measurements of more traditional communication. This research measured Sense of Community (SoC) and 'loneliness' in young adults in order to predict usage of Facebook. Participants were 154 Facebook users (82% female, mean age 23.66) who completed an online survey with four components (demographics, Facebook usage, SoC Index, and ...

Commodifying Scarcity: Society, Struggle, And Spectacle In World Of Warcraft, Kevin Moberly

English Faculty Publications

Overrun by monsters and tyrants, and ravaged by fanaticism, excess, and greed, World of Warcraft offers players a chance to struggle metaphorically against that which oppresses them: the excesses of late capitalism as they are represented by the game’s spectacular antagonisms. In order to take advantage of this opportunity, however, players must employ the very thing through which their oppression is manifested. Interpellated into the game as fetishized images, players must construct themselves and function in accordance with the limitations imposed upon them by the race and class of their characters. Players, as such, are incorporated into World of ...


The Changing Patterns Of Internet Usage, Christopher S. Yoo 2010 University of Pennsylvania Law School

The Changing Patterns Of Internet Usage, Christopher S. Yoo

Faculty Scholarship at Penn Law

The Internet unquestionably represents one of the most important technological developments in recent history. It has revolutionized the way people communicate with one another and obtain information and created an unimaginable variety of commercial and leisure activities. Interestingly, many members of the engineering community often observe that the current network is ill-suited to handle the demands that end users are placing on it. Indeed, engineering researchers often describe the network as ossified and impervious to significant architectural change. As a result, both the U.S. and the European Commission are sponsoring “clean slate” projects to study how the Internet might ...
