Encouraging Physical Activity In Teens: Can Technology Help Reduce Barriers To Physical Activity In Adolescent Girls?, Tammy Toscos, Anne Faber, Kay Connelly, Adity Mutsuddi-Upoma
Tammy R Toscos
Physical activity levels of girls decline dramatically during adolescence and may be a contributor to the increasing number of obese teens in the United States. Research has shown that social support is positively correlated with physical activity levels in adolescents, particularly girls. We present the findings from a three week field study of a mobile phone application designed to create a support group for physical activity within an existing social network of adolescent girls. Our findings suggest design considerations for technologies that encourage physical activity for this user group.

This study explores the roles federal (government) libraries and librarians play in scientific (international) knowledge development within federal agencies and in the larger scientific enterprise. In particular, this research looks at libraries’ and librarians’ facilitation of scientific inquiry through the application of research data services (RDS). Currently, librarians’ research and data consultation activities with administrators and researchers typically involve creating citations and finding datasets; less frequently, librarians are engaged in data management planning and other RDS activities. However, federal libraries and librarians have been identified as key stakeholders in collaborative science generally and specifically in scientific data cyberinfrastructures, such as …

ÜBerschussdaten In Retinabildern: Ein Beitrag Zum Datenschutzfreundlichen Entwurf Biometrischer Systeme, Michael Friedewald, Sebastian Wawrzyniak, Frank Pallas
Michael Friedewald
Die Retina ist wegen ihrer Unterscheidungskraft ein vielversprechendes biometrisches Merkmal, das vor allem für sicherheitsrelevante Systeme genutzt wird. Allerdings manifestieren sich auch zahlreiche Erkrankungen durch entsprechende Veränderungen der Retina. Die Nutzung solcher gesundheitsbezogener und für Zwecke der Authentifizierung unnötiger Daten ist daher unbedingt zu vermeiden. Dieser Beitrag befasst sich mit der Frage, welche gesundheitsrelevanten Informationen aus Retinabildern gewonnen werden können und welche Konsequenzen dies für den Entwurf biometrischer Systeme hat.

Assessing The Fit Between Child Welfare Information Systems And Frontline Workers: Development Of A Task-Technology Fit Instrument, Kurt William Heisler
Health Services Research Dissertations
States and the federal government continue to invest heavily in child welfare information systems (CWIS) to improve caseworkers' performance, but the extent to which these systems meet caseworkers' needs is unclear. In the field of child welfare there are no reliable user-evaluation measures states can use to assess the degree to which a CWIS meets caseworkers' needs, and identify which specific features of the CWIS most need improvement. The study developed such a measure based on the task-technology fit (TTF) framework, which posits that users will evaluate the usefulness of a technology based on how well it meets their tasks …

Ubiquitous social media during crises provides citizen reports on the situation, needs and supplies. Previous research extracts resource needs directly from the text (e.g. "Power cut to Coney Island and Brighton beach" indicates a power need). This approach assumes that citizens derive and write about specific needs from their observations, properly specified for the emergency response system, an assumption that is not consistent with general conversational behavior. In our study, Twitter messages (tweets) from Hurricane Sandy in 2012 clearly indicate power blackouts, but not their probable implications (e.g. loss of power to hospital life support systems). We use a domain …

Assessment Of Users' Information Security Behavior In Smartphone Networks, Mohammadjafar Esmaeili
Master's Theses and Doctoral Dissertations
With the exponential growth of smartphone usage, providing information security has become one of the main challenges that researchers and information-security specialists must consider. In contrast to traditional mobile phones that only enable people to talk and text, smartphone networks give users a variety of convenient functions such as connection to the Internet, online shopping, e-mail and social media, data storage, global positioning systems, and many other applications. Providing security in smartphone networks is critical for the overall information security of individuals and businesses. Smartphone networks could become vulnerable to security breaches if users do not practice safe behaviors such …

An Outlier Robust Block Bootstrap For Small Area Estimation, Payam Mokhtarian, Ray Chambers
Payam Mokhtarian
Small area inference based on mixed models, i.e. models that contain both fixed and random effects, are the industry standard for this field, allowing between area heterogeneity to be represented by random area effects. Use of the linear mixed model is ubiquitous in this context, with maximum likelihood, or its close relative, REML, the standard method for estimating the parameters of this model. These parameter estimates, and in particular the resulting predicted values of the random area effects, are then used to construct empirical best linear unbiased predictors (EBLUPs) of the unknown small area means. It is now well known …

Cities present an opportunity for rendering Web of Things-enabled services. According to the World Health Organization, population in cities will double by the middle of this century, while cities deal with increasingly pressing issues such as environmental sustainability, economic growth and citizen mobility. In this paper, we propose a discussion around the need for common semantic descriptions for smart city data to facilitate future services in "smart cities". We present examples of data that can be collected from cities, discuss issues around this data and put forward some preliminary thoughts for creating a semantic description model to describe and help …

Many machine learning datasets are noisy with a substantial number of mislabeled instances. This noise yields sub-optimal classification performance. In this paper we study a large, low quality annotated dataset, created quickly and cheaply using Amazon Mechanical Turk to crowdsource annotations. We describe computationally cheap feature weighting techniques and a novel non-linear distribution spreading algorithm that can be used to iteratively and interactively correcting mislabeled instances to significantly improve annotation quality at low cost. Eight different emotion extraction experiments on Twitter data demonstrate that our approach is just as effective as more computationally expensive techniques. Our techniques save a considerable …

In recent years there has been a renewed interest on science, technology, engineering, and mathematics (STEM) education. Following this interest, science centers' staff started providing technology enhanced informal STEM education experiences. The use of well-designed mobile and ubiquitous forms of technology to enrich informal STEM education activities is an essential success factor. The goal of our research is to investigate how technology applications can be better used and developed for taking full advantage of the opportunities and challenges they provide for students learning about STEM concepts. In our approach, we have conducted a series of interviews with experts from science …

Managing The Public To Manage Data: Citizen Science And Astronomy, Peter Darch
Peter Darch
Citizen Cyberscience Projects (CCPs) that recruit members of the public as volunteers to process and produce large datasets promise a great deal of benefits to scientists and science. However, if this promise is to be realised, and citizen science-produced datasets are to be widely-used by scientists, it is essential that these datasets win the trust of the scientific community. This task of securing credibility involves, in part, applying standard scientific procedures to clean-up datasets formed by volunteer contributions. However, the management of volunteers’ behaviour in terms of how they contribute also plays a significant role in improving both the quality …

Application Of Problem Based Learning And Mastery Learning To Multimedia Education, Gabriel J. Grant, Dominick E. Fazarro, Luke Steinke
Online Journal for Workforce Education and Development
The current state of education and the workforce demands a special kind of learner capable of creativity, communicating effectively, analytical skill application, critical thinking, and problem solving. Whereas these skills are important, it is also a necessity for learners to be masters of the knowledge and skills that they have acquired. Traditional educational methods have proven to be somewhat ineffective in producing these results. Problem based learning has proven worthy in handling some of the load, however, mastery learning has been abandoned long ago for reasons in spite of its effectiveness. Through given examples and careful design, the educator will …

Ten years ago, most people had never heard of celiac disease or gluten sensitivity, but awareness of these conditions have recently exploded, resulting in a craze to purchase gluten-free food items. Walk down the isles of Whole Foods or any other grocery store today and you will see labels for gluten free everywhere. These products were originally designed for people who have been diagnosed with a gluten digestive disorder. However, the gluten-free diet has expanded beyond those diagnosed with gluten sensitivity because millions of people are claiming it makes them feel better or helps them lose weight. In this paper, …

Bad Blood: Investigating The Ban On Msm Blood Donation, Lauren Lacy
CLAS: Colby Liberal Arts Symposium
In 1983, the Food and Drug Administration (FDA), responding to the AIDS epidemic, adopted a policy of deferring men who have had sex with men (MSM) at anytime since 1977 from donating blood. The current policy, adopted in 1992, continues to defer this group indefinitely. This paper investigates the societal implications of the deferred status. I will first examine the unique relationship gay and bisexual men have with the AIDS epidemic in American history.I challenge the FDAs claim that the ban is solely rooted in behavioral practices, using data on rates of contraction, behavioral practices relevant to MSM (condom use, …

Maines promising wind energy industry is growing and rural and island communities have begun pursuing wind turbine-generated electricity. The Fox Islands have, through the Fox Islands Electric Cooperative, successfully established a wind operation to provide the 1,500 island residents with electricity produced by three 1.5 megawatt turbines situated on Vinalhaven Island. However, shortly after the turbines began operation, a small but vocal group of Vinalhaven residents began to speak out against the noise issues they found as a product of living in the vicinity of the project. After numerous newspaper articles from both sides and formal complaints submitted to the …

On February 7, 2014, the day of Fisht Stadiums Winter Olympic Opening Ceremony, NBC ran an eight-hour tape-delay, releasing their idea of a more complete version of the 11:00 a.m. ET ceremony at 7:30 p.m. ET. The tape-delay allowed NBC to make edits to their film, which would include the exclusion of entire segments of the games. These abandoned segments, although no longer then five minutes each, depict a shifting image of Russia that gone unseen, can easily hinder American perceptions of Russia, allowing NBC to exploit dated notions of the countrys character. In the pages to follow, I will …

In this paper, we tackle a novel problem of mining contrast subspaces. Given a set of multidimensional objects in two classes C+ and C− and a query object o, we want to find top-k subspaces S that maximize the ratio of likelihood of o in C+ against that in C−. We demonstrate that this problem has important applications, and at the same time, is very challenging. It even does not allow polynomial time approximation. We present CSMiner, a mining method with various pruning techniques. CSMiner is substantially faster than the baseline method. Our …
