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 …

The Microenvironment Of Visceral Adipose Tissue And Liver Alter Natural Killer Cell Viability And Function, Melissa J. Conroy, Vivienne Fitzgerald, Suzanne Doyle, Shauna Channon, Zivile Useckaite, Niamh Gilmartin, Cliona O'Farrelly, Narayanasamy Ravi, John V. Reynolds, Joanne Lysaght

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 …

Negotiating Cultural Spaces In An International Mobile And Blended Learning Project, Charlotte Nirmalani Gunawardena, Agnieszka Palalas, Nicole Berezin, Caitlin Legere, Gretchen Kramer, Godwin Amo-Kwao

University Libraries & Learning Sciences Faculty and Staff Publications

This paper explores the cultural spaces that had to be negotiated by a team of North American and Ghanaian partners when designing, developing and implementing a mobile and blended learning solution to train physician assistants in Ghana. In addition, it examines how these cultural spaces correspond to five mobile and blended learning spaces: temporal, physical, transactional, technological and pedagogical. Employing qualitative narrative inquiry and paradigmatic analysis procedures, we analyzed six types of data to determine the cultural spaces that emerged. Results indicate that cultural spaces were most often negotiated in the transactional mobile and blended learning space and included: identity …

When The Fourth Estate Becomes A Fifth Column: The Effect Of Media Freedom And Social Intolerance On Civil Conflict, Marc L. Hutchison, Salvatore Schiano, Jenifer Whitten-Woodring

Political Science Faculty Publications

Media freedom is typically viewed as crucial to democracy and development. The idea is that independent news media will facilitate free and fair elections and shine a spotlight on corruption—thereby serving as a fourth estate. Yet political leaders often justify restricting media freedom on the grounds that irresponsible news coverage will incite political violence—potentially undermining government and in effect acting as a fifth column. So is media freedom a force for democracy or a source of civil conflict? We hypothesize that the effect of media freedom on civil conflict is conditioned by a country’s level of intolerance. Specifically, we predict …

When Partisans And Minorities Interact: Interpersonal Contact, Partisanship And Public Opinion Preferences On Immigration Policy, Shanna Pearson-Merkowitz, Alexandra Filindra, Joshua J. Dyck

Political Science Faculty Publications

Objective: Many studies investigating contact theory have suggested that contact effects are not universal but rather conditional. In this article, we test one form of conditional contact effects. Our approach posits that contact with out-groups produces support for pro-minority public policies only when in-group members are not subject to contrary messages from co-partisans.

Methods: We use data from an original survey to test this theory in the immigration policy domain.

Results: We find strong confirmatory evidence that the emergence of contact effects on support for a path to citizenship for undocumented immigrants is dependent on party identification. …

Social Media, Public Discourse And Civic Engagement In Modern China, Yinjiao Ye, Ping Xu, Mingxin Zhang

Political Science Faculty Publications

Drawing on the theoretical view of cyberspace’s role in engagement in public discourse and civic activities, the current study investigates how social media use is related to public discourse and civic engagement in mainland China. Moreover, we examine how political interest, general trust in people, and life satisfaction modify the interdependence of social media use and public discourse and civic engagement. Data analyses based on a survey of 1, 202 online Chinese show that social media use is significantly related to both public discourse and civic engagement. In addition, political interest has a consistent, strong modification on the role of …

Does Global Market Integration Weaken Opinion-Policy Congruence In The American States?, Bret Anderson, Brian S. Krueger, Ping Xu

Political Science Faculty Publications

Theories of economic globalization suggest that public opinion-public policy congruence should be affected by a state's degree of integration with international markets. With as much attention researchers have given to the opinion-policy linkage in the American states, it is surprising that this literature has neglected these well-known globalization frameworks. We take advantage of the wide variation in U.S. states’ integration in global markets, public policies, and political orientations of citizens, to assess whether global market integration depresses the association between citizen opinion and public policies. Using three decades of state-level data, our results suggest that high global market integration does …

Trust In China? The Impact Of Development, Inequality, And Openness On Political Trust Across China’S Provinces, 2001-2012, Marc L. Hutchison, Ping Xu

Political Science Faculty Publications

China has long represented a puzzle for scholars of democracy, who view political trust as an important indicator of regime legitimacy. Previous studies show that while democracies around the world experienced declining levels of political trust, the authoritarian Chinese government maintained unexpectedly high levels of trust. Using World Value Survey (WVS) data over a critical twelve-year period (2001-2012) and multilevel modeling techniques, we explore both macro- and individual-level determinants of political trust in China. We find that province-level economic performance and individual level income combine to influence political trust. Higher levels of individual-level income have a positive effect on trust …

Defeating Isis On The Battle Ground As Well As In The Online Battle Space: Considerations Of The “New Normal” And Available Online Weapons In The Struggle Ahead, Anne Speckhard, Ph.D., Ardian Shajkovci, Ph.D., Ahmet S. Yayla, Ph.D.

Journal of Strategic Security

The United States and its allies continue to achieve significant military victories against ISIS (otherwise known as ISIL or the “Islamic State”). The loss of territories resulting from military victories is especially important given that ISIS relies in part on recruits from the territories it controls. Efforts have also been directed at killing the group’s core leadership; stemming the flow of foreign fighters to Iraq and Syria through tightening up border security and surveillance; and targeting militant jihadi narratives and propaganda that is pushed out by ISIS on a twenty-four/seven basis via the Internet and social media platforms. In such …

Wicked Problems: How Complexity Science Helps Direct Education Responses To Preventing Violent Extremism, Lynn Davies

Journal of Strategic Security

This article draws on the insights from complexity science to outline potential strategies within education which could interrupt the spread of violent extremism. It first identifies three problems in examining extremism - definitions, causes and targets—before arguing for a focus on systems, not individual learners. Within systems, diversity is needed for emergence, and narrow, hard secularism is rejected in favor of a dynamic secularism which encourages a variety of belief systems in order to guard against polarization. The systems of education, religion, law and of terrorism itself are analyzed to identify entry points and vulnerabilities. After looking at the theories …

I See! Scotland: Tackling Sectarianism And Promoting Community Psychosocial Health, Eolene M. Boyd-Macmillan, Patricia Andrews Fearon, Amanda M. Ptolomey, Laura J. Mathieson

Journal of Strategic Security

We developed and tested through two studies a new intervention run as a course, I SEE! Scotland, to reduce and prevent Protestant-Catholic sectarianism in Scotland, a historic inter-group conflict expressed in forms ranging from polite to violent, within a wider population that includes those who feel untouched. Designed to reflect the social ecology of Scotland and engage individuals regardless of sectarian involvement, the intervention aimed to increase cognitive complexity, measured as integrative complexity, through participatory theatre and experiential methods. We hypothesised that the confluence of experiential learning to support multiple forms of self, other, and systems awareness with narrative framing …

Increasing Cognitive Complexity And Collaboration Across Communities: Being Muslim Being Scottish, Eolene M. Boyd-Macmillan

Journal of Strategic Security

Being Muslim Being Scottish (BMBS) joins a family of IC interventions, Being Muslim Being British (BMBB) and Being Kenyan Being Muslim (BKBM). Like BMBB and BKBM, the newest family member, BMBS, is designed to increase cognitive complexity management by enabling participants to identify and access a wider range of their own values (value pluralism). Increased cognitive management capacities enable movement from rapid, inflexible, closed, black and white thinking that sees no validity in other viewpoints toward more deliberate, flexible, open thinking that can tolerate shades of grey, and see validity in other viewpoints without sacrificing one’s core values. Piloted …

An Ic Intervention For Post-Conflict Northern Ireland Secondary Schools, Eolene M. Boyd-Macmillan, Claire Campbell, Andrea Furey

Journal of Strategic Security

Without carefully planned, sustained resourcing of children and young people, post-conflict Northern Ireland (NI) may fail to flourish. In May, 2016, MI5 (the UK domestic security agency) increased the security threat level from moderate to substantial for NI related terrorism. For over two years we have been partnership building in post-conflict NI to produce a plan for developing an evidence-based integrative complexity resource for NI secondary schools. Integrative complexity interventions have been shown effective at increasing capacities in a range of contexts, on different conflicts and extremisms, with diverse population samples (evaluated using the cross-culturally validated integrative complexity measurement frame). …

Latent Memories Of Terror: Media Perceptions Of The Woolwich Attack, Logan Stickel

Journal of Strategic Security

The Woolwich Attack of 2013 remains a distinctive case of lone wolf terrorism in terms of its hyper violent theatricalization and symbolic presentation of user-generated content. Although being described as having a paradigmic effect on the way terrorism is viewed and presented, its relationship to traditional media is under examined. To understand the perceptive impact, an exploratory qualitative research project was designed to gauge public views in terms of event presentation by media modality. Primary data was collected through interviews upon a theoretical sampling of fifteen Londoners and interpreted using a framework analysis technique. Results indicated that the main mode …

Iron Phosphide Nanostructures As An Efficient Bifunctional Catalysts For Water Splitting, Nikitaa Ashokan

Masters Theses

"The first part of this thesis work focuses on developing a bifunctional catalyst for electrochemical water splitting encompassing both oxygen and hydrogen evolution. A highly efficient catalyst is necessary to improve kinetics of the sluggish four electron process for oxygen evolution reaction (OER) and two-electron process for hydrogen evolution reaction (HER). Recently, transition metal phosphides have gained increasing interest in this field because of their good electrical conductivity properties as well as better catalytic activity. Many transition-metal phosphides are being considered for this application and iron phosphide (FeP) has proved to be a good HER catalyst. In this work, we …

Experimental Evaluations Of Selected Sealants To Remediate Co₂ Leakage, Aaron Jeffrey Blue

Masters Theses

"Carbon Dioxide (CO₂) sequestration into porous and permeable brine-filled aquifers is seen as one of the most feasible solutions for reducing the amount of greenhouse gases released into the atmosphere from coal-fired power plants. To safely store the CO₂, it must be trapped under an impermeable rock acting as a seal. One of the concerns with CO₂ sequestration is the generation of new fractures or reopening of existing fractures caused by CO₂ injection in the sealing formation. This project evaluates the potential of sealing these fractures by injecting sealing materials into them. These sealing …

Automated Channel Emulator Based On Mems Switch And Improvement Of Signal Transition, Jingdong Sun

Masters Theses

"Channel Emulator, which is widely used in communication system development, is an instrument that emulates the real-world signal propagation environment between transmitter and. [sic] To overcome the disadvantages of traditional channel emulator, we propose a novel structure of the automated channel emulator in Section 1, which can be controlled by software and integrated into auto-testing system. MEMS switch, with good RF performance, is used to connect and isolate multiple channels.

In Section 2, we divide the whole channel emulator system into Channel, Support, and Controller Board, and provide detailed design procedures with critical parameters of each board. The well-designed high …

Fluid Flow Through Deformation Band, Huining Zhang

Masters Theses

"Cataclastic deformation bands, which are common in porous sandstone, have the potential to restrict fluid flow. Geological studies have shown that permeability of deformation band shear zones can be one to five orders of magnitude less than for the sandstone host rock. However, recent studies based on simplified analytical estimates have shown that fluid flow in jointed deformation bands may not be retarded since joints play an important role in conducting fluids. In this study, 2 dimensional finite element analysis (FEA) is used to simulate the total discharge flow rate through jointed deformations. Variations of single planar and conjugate jointed …

Integration Of New Biological And Physical Retrospective Dosimetry Methods Into Eu Emergency Response Plans – Joint Reneb And Eurados Inter-Laboratory Comparisons, Elizabeth Ainsbury, Christophe Badie, Stephen Barnard, Aidan Meade

Articles

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 …
