A New Educational Mobile Devices Platform For Social Inclusion In Tanzania, Fredrick Mtenzi

Articles

Abstract— It is evident that advances in technology has led to improvement in societal wellbeing. In this paper we demonstrate how mobile phones are used in providing reliable and quality education to students in disadvantaged areas of Tanzania. The main contribution is on leveraging on the success that Tanzania has had on using mobile banking to the un-banked population. These lessons are adapted to the education sector, where clever/smart integration of existing disruptive technologies such as mobile phones and social networks are be used to provide access to high quality educational contents. Further, the paper shows how educational content can …

Reentering Survivors: Invisible At The Intersection Of The Criminal Legal System And The Domestic Violence Movement, Courtney K. Cross

Articles

Like all returning citizens, women coming home after incarceration face significant challenges to successful reentry. In addition to the collateral consequences of their criminal convictions, reentering women also encounter uniquely gendered obstacles. This Article explores one such obstacle: the relationship between women's reentry and domestic violence. Women on probation or parole who are also experiencing domestic violence too often fall into a blind spot in which the structure of community supervision pressures them to remain in unsafe homes and also punishes them when the abuse they endure interferes with their ability to comply with the conditions of their release. Because …

Ingress Well-Played: City As Mmo, Elizabeth L. Lawley

Articles

This paper describes player experience for Ingress, a geo-local, mobile augmented reality game created by Google’s Niantic Labs. Ingress incorporates aspects of both pervasive, alternate reality (ARG) and massively multiplayer online (MMO) games. However, unlike many ARGs, Ingress is not focused on a specific time-limited period, or linked to a single real-world event or location. And unlike a typical MMO, play in Ingress is geo-spatially limited; players must be physically proximate to game elements in order to interact with them. Using game mechanics similar to those of many MMOs, Ingress provides for a range of gameplay, based both on …

Controlling Microbial Safety Challenges Of Meat Using High Voltage Atmospheric Cold Plasma, Lu Han, Dana Ziuzina, Caitlin Marie Heslin, Daniela Boehm, Apurva Patange, David Millan-Sango, Vasilis Valdramidis, Patrick J. Cullen, Paula Bourke

Articles

Atmospheric cold plasma (ACP) is a non-thermal technology, effective against a wide range of pathogenic microorganisms. Inactivation efficacy results from plasma generated reactive species. These may interact with any organic components in a test matrix including the target microorganism, thus food components may exert a protective effect against the antimicrobial mode of action. The effect of an in-package high voltage ACP process applied in conjunction with common meat processing MAP gas compositions as well as bacteria type and meat model media composition have been investigated to determine the applicability of this technology for decontamination of safety challenges associated with meat …

Atmospheric Cold Plasma Interactions With Modified Atmosphere Packaging Inducer Gases For Safe Food Preservation., Lu Han, Daniela Boehm, Vladimir Milosavljević, Ester Amias, Patrick J. Cullen, Paula Bourke

Articles

Diverse microbiological challenges and pervasive microbial resistance drive technological development in food processing, where increasing process complexity and consumer demand for less processed goods leads to strong demand for effective decontamination. Atmospheric cold plasma (ACP) has wide potential for decontamination application in the food sector. We investigated the effect of Modified Atmosphere Packaging (MAP) gas mixtures on reactive species generated, their efficacy and mechanism of inactivation against Escherichia coli, Listeria monocytogenes and Staphylococcus aureus. Oxygen levels in the applied working gas had positive interactive effects on ROS generation, in-package inactivation efficacy in conjunction with post-treatment storage time. …

Cytotoxic And Mutagenic Potential Of Solutions Exposed To Cold Atmospheric Plasma, Daniela Boehm, Caitlin Heslin, P.J. Cullen, Paula Bourke

Articles

The exposure of aqueous solutions to atmospheric plasmas results in the generation of relatively long-lived secondary products such as hydrogen peroxide which are biologically active and have demonstrated anti-microbial and cytotoxic activity. The use of plasma-activated solutions in applications such as microbial decontamination or anti-cancer treatments requires not only adequate performance on target cells but also a safe operating window regarding the impact on surrounding tissues. Furthermore the generation of plasma-activated fluids needs to be considered as a by-stander effect of subjecting tissue to plasma discharges. Cytotoxicity and mutagenicity assays using mammalian cell lines were used to elucidate the effects …

Judicial Wisdom Or Patent Envy? The Eleventh, Seventh And Federal Circuits’ Patent Jurisdictional Battle, Xuan-Thao Nguyen

Articles

This article observes a startling new appellate jurisdictional battle waged by regional circuit courts to chip away the Federal Circuit's exclusive jurisdiction in patent cases. The Eleventh Circuit took an unprecedented step by engaging in patent claim construction and infringement under literal infringement analysis and the doctrine of equivalents analysis. In a case of first impression, the Eleventh Circuit asserted that it legitimately has appellate jurisdiction to decide cases involving substantive patent law. Instead of grabbing jurisdiction, the Seventh Circuit, through its Chief Judge, grabbed public attention by advocating for the abolishment of the Federal Circuit's exclusive jurisdiction over patent …

Privacy, Public Disclosure, Police Body Cameras: Policy Splits, Mary D. Fan

Articles

When you call the police for help—or someone calls the police on you—do you bear the risk that your worst moments will be posted on YouTube for public viewing? Police officers enter some of the most intimate incidences of our lives—after an assault, when we are drunk and disorderly, when someone we love dies in an accident, when we are distraught, enraged, fighting, and more. As police officers around the nation begin wearing body cameras in response to calls for greater transparency, communities are wrestling with how to balance privacy with public disclosure.

This Article sheds light on the balances …

Regulating Unicorns: Disclosure And The New Private Economy, Jennifer S. Fan

Articles

“Unicorns” are private companies with valuations of a billion dollars or more. As their name indicates, unicorns were originally so rare as to be almost mythical. But Uber and other technology companies have ushered in a new era: we now have a blessing of unicorns, each one of which has the potential to transform financial and cultural norms.

Yet from a legal perspective, these behemoths are regulated just like their much smaller, non-mythical counterparts. Unicorns’ dizzying valuations have not been matched with any expansion or recalibration of regulation. As a result, vital information about these companies remains secret, perhaps for …

The Secession Of The Successful: The Rise Of Amazon As Private Global Consumer Protection Regulator, Jane K. Winn

Articles

In 2005, the Americans for Fair Electronic Commerce Transactions (“AFFECT”) coalition issued a list of 12 principles it hoped would contribute to a new consensus about what constitutes fairness in online consumer transactions. A decade later, a cursory review of different jurisdictions indicates that, while there has been little discernable progress in the direction of the principles in the United States, other jurisdictions such as the European Union have made more progress.

However, the one jurisdiction in the world that comes closest to implementing all 12 principles across the full spectrum of consumer transactions is not a government at all, …

Influence Of Ionic Liquids On The Selectivity Of Ion Exchange-Based Polymer Membrane Sensing Layers, Lukasz Mendecki, Nicole Callan, Meghan Ahern, Benjamin Schazmann, Aleksandar Radu

Articles

The applicability of ion exchange membranes is mainly defined by their permselectivity towards specific ions. For instance, the needed selectivity can be sought by modifying some of the components required for the preparation of such membranes. In this study, a new class of materials –trihexyl(tetradecyl)phosphonium based ionic liquids (ILs) were used to modify the properties of ion exchange membranes. We determined selectivity coefficients for iodide as model ion utilizing six phosphonium-based ILs and compared the selectivity with two classical plasticizers. The dielectric properties of membranes plasticized with ionic liquids and their response characteristics towards ten different anions were investigated using …

Use Of A Web-Based Dietary Assessment Tool In Early Pregnancy, Laura Mullaney, Amy C. O'Higgins, Shona Cawley, R. Kennedy, Daniel Mccartney, M.J. Turner

Articles

Background Maternal diet is critical to fetal development and lifelong health outcomes. In this context, dietary quality indices in pregnancy should be explicitly underpinned by data correlating food intake patterns with nutrient intakes known to be important for gestation.

Aims Our aim was to assess the correlation between dietary quality scores derived from a novel online dietary assessment tool (DAT) and nutrient intake data derived from the previously validated Willett Food Frequency Questionnaire (WFFQ).

Methods 524 women completed the validated semiquantitive WFFQ and online DAT questionnaire in their first trimester. Spearman correlation and Kruskal–Wallis tests were used to test associations …

Articles

The role of NK cells in visceral adipose tissue (VAT) and liver inflammation in obesity is not fully understood. This study investigated the frequency, cytokine expression, chemokine receptor, and cytotoxicity receptor profile of NK cells in the blood, omentum, and liver of patients with the obesity-associated cancer, oesophageal adenocarcinoma (OAC). The effect of chronically inflamed tissue microenvironments on NK cell viability and function was also examined. We identified significantly lower NK cell frequencies in the liver of OAC patients compared with healthy controls and within the omentum and liver of OAC patients compared with blood, whereas IL-10-producing populations were significantly …

RENEB, 'Realising the European Network of Biodosimetry and Physical Retrospective Dosimetry,' is a network for research and emergency response mutual assistance in biodosimetry within the EU. Within this extremely active network, a number of new dosimetry methods have recently been proposed or developed. There is a requirement to test and/or validate these candidate techniques and inter-comparison exercises are a well-established method for such validation.

A Novel Anthropomorphic Flow Phantom For The Quantitative Evaluation Of Prostate Dce-Mri Acquisition Techniques, Silvin Knight, Jacinta Browne, James Meaney, David Smith, Andrew Fagan

Articles

A novel anthropomorphic flow phantom device has been developed which can be used for quantitatively assessing the ability of MRI scanners to accurately measure signal / concentration time-intensity curves (CTCs) associated with dynamic contrast-enhanced (DCE) MRI. Modelling of the complex pharmacokinetics of contrast agents as they perfuse through the tumour capillary network has shown great promise for cancer diagnosis and therapy monitoring. However, clinical adoption has been hindered by methodological problems, resulting in a lack of consensus regarding the most appropriate acquisition and modelling methodology to use and a consequent wide discrepancy in published data. A heretofore overlooked source of …

Screening For Peripheral Arterial Disease And Carotid Artery Disease In Patients With Abdominal Aortic Aneurysm, C. Gray, Patrick J. Goodman, Paul Cullen, Stephen Badger, Kevin O'Malley, Martin K. O'Donohoe, Ciarán O. Mcdonnell

Articles

Screening for concomitant atherosclerotic disease is important in cardiovascular risk reduction. This study assessed the prevalence of carotid artery disease (CAD) and peripheral arterial disease (PAD) in patients with known abdominal aortic aneurysms (AAAs). All patients with AAA attending the vascular laboratory between the January 1, 2007, and December 31, 2009, were eligible for a carotid ultrasound and measurement of ankle brachial indices. A total of 389 (305 males) patients were identified on the AAA surveillance program with a mean (±standard deviation) age of 76 (±8) years. The mean age of the males was 75.4 (±7.8) years, and the mean …

Strategy/Enterprise Discourse Bounds In Business Talk., Brendan O'Rourke

Articles

Corporate strategy emerged as large non-owner managed firms became economically important (Knights and Morgan, 1991). Strategy became the substitute for the earlier enterprise discourse, which depended on the dominance, in entrepreneurial capitalism, of owner-managed firms. The discourses of strategy and enterprise developed as separate academic areas and as logics of two very different economic domains. From the late 1970s however, large organizations (Kanter, 1983:27) and governments have been urged to be more entrepreneurial (Klein et al., 2010; Osborne and Gaebler, 1993). Meanwhile, small firms were encouraged to be more strategic (Carr, 2000). This article looks at evidence from small …

Legitimising Expertise: Analysing The Legitimation Strategies Used By Economics Experts In Broadcast Interviews, Joseph K. Fitzgerald, Brendan O'Rourke

Articles

Few would doubt that economists have taken a prominent role as experts on policy issues [Maesse, J. 2015. Economic experts: A discursive political economy of economics. Journal of Multicultural Discourses 10, no.3: 279–305] and some contend that no other social science discipline has gained such prominence [Fourcade, M., E. Ollion, and Y. Algan. 2015. The superiority of economists. Journal of Economic Perspectives 29, no.1: 89–114]. This prominent societal role has long been evident and leans on their perceived objectivity with regard to the economy and policy advice. Yet, the Great Recession of 2008 put past understandings of the economy, and …

Linocin And Ompw Are Involved In Attachment Of The Cystic Fibrosis-Associated Pathogen Burkholderia Cepacia Complex To Lung Epithelial Cells And Protect Mice Against Infection, Siobhan Mcclean, Marc Healy, Cassandra Collins, Stephen Carberry, Luke O'Shaughnessy, Ruth Dennehy, Aine Adams Aine Adams, Helen Kennelly, Jennifer Corbett, Fiona Carty, Laura Ann Cahill, Máire Callaghan, Karen English, Bernard P. Mahon, Sean Doyle, Minu Shinoy

Articles

Burkholderia cepacia complex (Bcc) causes chronic opportunistic lung infections in people with cystic fibrosis (CF) resulting in a gradual lung function decline and, ultimately, patient death. Bcc is a complex of eighteen species and is rarely eradicated once a patient is colonised, therefore vaccination may represent a better therapeutic option. We developed a new proteomics approach to identify bacterial proteins that are involved in attachment of Bcc to lung epithelial cells. Fourteen proteins were reproducibly identified by 2-DE from four Bcc strains, representative of two Bcc species: B. cenocepacia, the most virulent and B. multivorans, the most frequently acquired. Seven …

Iron Acquisition In The Cystic Fibrosis Lung And Potential For Novel Therapeutic Strategies, Jean Tyrrell, Máire Callaghan

Articles

Iron acquisition is vital to microbial survival and is implicated in the virulence of many of the pathogens that reside in the cystic fibrosis (CF) lung. The multifaceted nature of iron acquisition by both bacterial and fungal pathogens encompasses a range of conserved and species-specific mechanisms, including secretion of iron-binding siderophores, utilization of siderophores from other species, release of iron from host iron-binding proteins and haemoproteins, and ferrous iron uptake. Pathogens adapt and deploy specific systems depending on iron availability, bioavailability of the iron pool, stage of infection and presence of competing pathogens. Understanding the dynamics of pathogen iron acquisition …

Legal Capacity For All: Including Older Persons In The Shift From Adult Guardianship To Supported Decision-Making, Rebekah Diller

Articles

For the last several decades, guardianship has been the subject of continual calls for reform, often spurred by revelations of guardian malfeasance and other abuses in the system. Recent developments in international human rights law pose a more fundamental challenge to the institution. Under Article 12 of the United Nations Convention on the Rights of Persons with Disabilities (CRPD), governments may not deprive individuals of their “legal capacity”—or right to make decisions and have those decisions recognized as legally binding—on the grounds of disability. In the wake of the CRPD, the concept of supported decision-making has gained growing acceptance as …

The Moral Psychology Of Copyright Infringement, Christopher Buccafusco, Dave Fagundes

Articles

Numerous recent cases illustrate that copyright owners sue for infringement even when an unauthorized use of their work causes them no economic harm. This presents a puzzle from the perspective of copyright theory as well as a serious social problem, since infringement suits designed to remedy non-economic harms tend to stifle rather than encourage creative production. While much scholarship has critiqued copyright’s economic theory from the perspective of authors’ incentives to create, ours is the first to explore this issue from the perspective of owners’ motivations to sue for infringement. We turn to moral psychology, and in particular to moral …

A Tale Of Three Markets: Comparing The Renewable Energy Experiences Of California, Texas, And Germany, Felix Mormann, Dan Reicher, Victor Hanna

Articles

The Obama administration has repeatedly identified the large-scale build-out of clean, renewable energy infrastructure as a key priority of the United States. The President's calls for a cleaner energy economy are often accompanied by references to other industrialized countries such as Germany, hailed by many as a leader in renewable energy deployment. Indeed, the share of renewables in Germany's electricity generation mix is twice that of the United States, and the ambitious "Energiewende" commits the country to meeting 80% of its electricity needs with renewables by 2050. While some praise the German renewables experience as successful proof of concept, others …

"Immigrants Are Not Criminals": Respectability, Immigration Reform, And Hyperincarceration, Rebecca Sharpless

Articles

Mainstream pro-immigrant law reformers advocate for better treatment of immigrants by invoking a contrast with people convicted of a crime. This Article details the harms and limitations of a conceptual framework for immigration reform that draws its narrative force from a contrast with people-citizens and noncitizens-who have been convicted of a criminal offense and proposes an alternate approach that better aligns with racial and class critiques of the U.S. criminal justice system. Noncitizens with a criminal record are overwhelmingly low-income people of color. While some have been in the United States for a short period of time, many have resided …

Better Than Bankruptcy?, Andrew B. Dawson

Articles

According to many in the bankruptcy field, small business debtors are increasingly turning to state debtor-creditors laws as an alternative to federal bankruptcy relief. One particularly popular state law is the assignment for the benefit of creditors. The conventional wisdom is that these procedures provide a state law alternative to liquidate a business.

This article reports the results of an original empirical study that challenges this conventional wisdom. Gathering data from every assignment for the benefit of creditors in a major metropolitan area over a three-year period, this study shows that debtors and their secured creditors are using these procedures …
