Comparison Of Pre-Intervention Idi Results From Stem And Non-Stem Undergraduate Students, Anne M. Lucietto, Liza Russell

Journal of Global Education and Research

The emphasis on intercultural competence is more prevalent in STEM (Science, Technology, Engineering and Mathematics) majors as the world shifts towards a more globalized economy. When entering higher education, students have differing levels of cultural interaction due to varying peer interaction, family experiences, international travel, and social media experiences. The Intercultural Development Inventory (IDI) has been used to develop an understanding of how students view others and the level of skills they have to interact and adapt to other cultures. Using published data focused on pre-intervention assessment, researchers compared it to data obtained from STEM students preparing for an international …

Global Citizenship Education Starts With Teacher Training And Professional Development, Evan Saperstein

Journal of Global Education and Research

In recent years, the idea of global citizenship has grown in scholarly circles and developed into a nascent discipline known as global citizenship education. As a general matter, global citizenship education strives to deepen cross-cultural understanding through the study of current transnational issues. This qualitative, interpretivist case study examined the roles and responsibilities of global studies teachers at an urban New Jersey public high school. The study included interviews with an administrator, two global studies teachers, and six students enrolled in the second sequence of a two-year course in the global studies curriculum; as well as observations and analysis of …

Network-Level Mechanisms Underlying Effects Of Transcranial Direct Current Stimulation (Tdcs) On Visuomotor Learning, Pejman Sehatpour, Clément Dondé, Matthew J. Hoptman, Johanna Kreither, Devin Adair, Elisa Dias, Blair Vail, Stephanie Rohrig, Gail Silipo, Javier Lopez-Calderon, Antigona Martinez, Daniel C. Javitt

Publications and Research

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation approach in which low level currents are administered over the scalp to influence underlying brain function. Prevailing theories of tDCS focus on modulation of excitation-inhibition balance at the local stimulation location. However, network level effects are reported as well, and appear to depend upon differential underlying mechanisms. Here, we evaluated potential network-level effects of tDCS during the Serial Reaction Time Task (SRTT) using convergent EEG- and fMRI-based connectivity approaches. Motor learning manifested as a significant (p <.0001) shift from slow to fast responses and corresponded to a significant increase in beta-coherence (p <.0001) and fMRI connectivity (p <.01) particularly within the visual-motor pathway. Differential patterns of tDCS effect were observed within different parametric task versions, consistent with network models. Overall, these findings demonstrate objective physiological effects of tDCS at the network level that result in effective behavioral modulation when tDCS parameters are matched to network-level requirements of the underlying task.

Machine Learning Based Predictions Of Dissolved Oxygen In A Small Coastal Embayment, Manuel Valera, Ryan K. Walter, Barbara A. Bailey, Jose E. Castillo

Physics

Coastal dissolved oxygen (DO) concentrations have a profound impact on nearshore ecosystems and, in recent years, there has been an increased prevalance of low DO hypoxic events that negatively impact nearshore organisms. Even with advanced numerical models, accurate prediction of coastal DO variability is challenging and computationally expensive. Here, we apply machine learning techniques in order to reconstruct and predict nearshore DO concentrations in a small coastal embayment while using a comprehensive set of nearshore and offshore measurements and easily measured input (training) parameters. We show that both random forest regression (RFR) and support vector regression (SVR) models accurately reproduce …

Improving The Accuracy Of Genomic Predictions: Investigation Of Training Methods And Data Pooling, Johnna Lynn Baller

Department of Animal Science: Dissertations, Theses, and Student Research

One of the primary factors in the response to selection is the accuracy of selection. This study focused on methodologies to predict breeding values (BV) accurately within multi- and single-step genomic evaluations. Factors including cross-validation methods, dependent variables, and genotyping strategies were assessed on the accuracy of genomic BV while using multi-step prediction in real and simulated data. In both cases, random clustering led to largest estimated accuracies compared to clusters based on k-means, k-medoids, and principle component analysis, but differences in bias were not detected. Using deregressed estimated BV (EBV) to estimate SNP effects led to larger accuracies and …

The Effects Of Covid-19 On Domestic Violence And Immigrant Families., Abha Rai, Susan Grossman, Nathan Perkins

Social Work: School of Social Work Faculty Publications and Other Works

The COVID-19 pandemic has threatening implications for all individuals; and has been particularly unsettling for immigrants. Given their unique positionality in the U.S., the intersectional discussion about the impact of this pandemic on immigrants and issues of family violence is salient. The position of some groups of immigrant women is even more precarious due to the increased dependency on their spouse/partner for emotional, economic and immigration-related reasons. While immigrants have been on the frontlines as responders for COVID-19, there are limited policies that provide them with healthcare, employment guarantee, or benefits. Further, the immigration restrictions created by the U.S. Government …

How College Students Created Opportunities For Sweatshop Workers: The Anti-Sweatshop Movement And An Interactive Approach To Political Opportunity Structure, Matthew Williams

Sociology: Faculty Publications and Other Works

Political opportunity structure (POS) refers to how the larger social context, such as repression, shapes a social movement's chances of success. Most work on POS looks at how movements deal with the political opportunities enabling and/or constraining them. This article looks at how one group of social movement actors operating in a more open POS alters the POS for a different group of actors in a more repressive environment through a chain of indirect leverage—how United Students Against Sweatshops (USAS) uses the more open POS on college campuses to create new opportunities for workers in sweatshop factories. USAS exerts …

Current And Projected Water Reuse For Irrigation In Utah, R. Ryan Dupont, Joan E. Mclean, Randal S. Martin, Courtney Flint, L. Niel Allen, Jennifer L. Weidhaas

Reports

Reuse of treated wastewater for irrigation in some cases can help meet increasing agriculture and urban water demands in Utah. The last report describing existing and potential reuse efforts in Utah was in 2005 (Utah Division of Water Resources, 2005). This report provides information on existing and proposed water reuse and perceptions among water providers and users regarding the use of reclaimed wastewater. Wastewater reuse is one of many practices to conserve water and improve water quality. In a broad sense, water reuse occurs by downstream users, but in some cases, deliberate strategic reuse of water is undertaken to provide …

Decentralized Event-Triggered Control In The Presence Of Adversaries, Paul Griffioen, Raffaele Romagnoli, Bruce H. Krogh, Bruce Sinopoli

Faculty Work Comprehensive List

Decentralized control systems are widely used in a number of situations and applications. In order for these systems to function properly and achieve their desired goals, information must be propagated between agents. However, communication between agents entails connecting to a network, potentially allowing adversaries to infiltrate the system through the network and attack multiple agents. To increase resiliency against these attacks, it is desirable for agents to operate disconnected from the network as much as possible, only communicating with other agents when it is absolutely necessary to achieve their goal or to maintain the safety of the overall system. This …

“We Have A Lot Of Home Deliveries” A Qualitative Study On The Impact Of Covid-19 On Access To And Utilization Of Reproductive, Maternal, Newborn And Child Health Care Among Refugee Women In Urban Eastleigh, Kenya, Adelaide Lusambili, Michela Martini, Faiza Abdirahman, Abena Asante, Sharon Ochieng, Joseph N. Guni, Rose Maina, Stanley Luchters

Population Health, East Africa

Background: Little is known about how pregnant refugee women, and the frontline health care workers who serve them, are affected by the COVID-19 pandemic in terms of health, and health service access. Women refugees are classified as a vulnerable group with regard to pregnancy outcomes and access to maternal care, and may be disproportionally at risk for COVID-19 infection as they are likely to face unique barriers to information and access to reproductive health services during the pandemic. Few studies identify gaps that could inform potential interventions to improve service uptake for refugee women, particularly in the context of …

Critical Thinking In A Service-Learning Course: Impacts Of Information Literacy Instruction, Heather R. Kennedy, Anne Marie H. Gruber

Communications in Information Literacy

It is well demonstrated that service-learning positively impacts a variety of student outcomes. However, methodological limitations have contributed to a lack of clear understanding of the mechanisms through which these effects occur. Additionally, little research has connected information literacy instruction explicitly with outcomes in service-learning courses. The present study used a pre-/post-test design to investigate cognitive outcomes, including critical thinking, using the Problem-Solving Analysis Protocol (P-SAP). Fifty-nine students from an undergraduate family services course participated. Results highlight the importance of library instruction to students’ critical thinking skills and suggest implications for collaborations between discipline faculty and library faculty in service-learning …

Elite human and animal athletes must acquire the fuels necessary for extreme feats, but also contend with the oxidative damage associated with peak metabolic performance. Here, we show that a migratory bird with fuel stores composed of more omega-6 polyunsaturated fats (PUFA) expended 11% less energy during long-duration (6 hr) flights with no change in oxidative costs; however, this short-term energy savings came at the long-term cost of higher oxidative damage in the omega-6 PUFA-fed birds. Given that fatty acids are primary fuels, key signaling molecules, the building blocks of cell membranes, and that oxidative damage has long-term consequences for …

Cognitivevr: Memory Training For Dementia Patients, Daniel Phill

Postgraduate

Around 50 million people suffer from dementia worldwide (World Health Organisation, 2019). One of the worst symptoms of dementia is memory loss as it affects not only the sufferer but their family as well. Recent studies have demonstrated that the immersion of virtual reality has the potential to improve memory in the general public (Krokos, Plaisant, Varshney, 2018) and that dementia patients are able to use virtual reality (Flynn, Schaik, Blackman, Femcott, Hobbs & Calderon, 2004). In this paper, I examine the literature linking virtual reality and dementia care and explain how I used this in my creative practice to …
