Event-Related Potentials Of Individuals With Attention-Deficit/Hyperactivity Disorder Performing The Attention Network Task, P. Dennis Rodriguez, Justin E. Stauffacher

Midwest Social Sciences Journal

The current study sought to investigate the neural basis of attention-deficit/hyperactivity disorder (ADHD) by examining the performance of individuals with ADHD on the Attentional Networks Test (ANT) by Fan, McCandliss, Sommer, Raz, and Posner (2002), while recording electroencephalography (EEG) utilizing event-related potentials (ERP) methodology. Fifty-seven university students were divided into three groups: control, ADHD-inattentive subtype (ADHD-IA), and ADHD-combined/hyperactive impulsive subtype (ADHD-C/HI). The average peak amplitudes of the P300 waveform for each group were compared and analyzed for performance on each attention network measured by the ANT: the alerting network, the orienting network, and the executive control network. The average P3 …

Personal Factors Influencing Us Travelers’ Sentiments Toward Travel Policies To Cuba, Carol Kline, Whitney Knollenberg, Bynum Boley, Evan Jordan

Journal of Tourism Insights

The United States and Cuba have navigated a strained political and economic relationship over the past sixty years; the tone of the relationship is in flux according to Cuban and US leadership, and most recently, COVID-19. Anticipating US travelers’ sentiments towards access to Cuba is more crucial now because of resulting policies playing out within the intersection of the shifting dynamics of the virus and the tumultuous political climate within the US.

Household Salt Production By The Late Classic Maya: Underwater Excavations At Ta'ab Nuk Na, Heather Mckillop, E. Cory Sills

Faculty Publications

Salt is an essential commodity; archaeological remains around the world attest to the importance of its production, exchange and consumption. Often located in coastal locations, many production sites were submerged by rising seas, including the Paynes Creek Salt Works on the southern Belize coast. Survey and excavation of these sites has identified 'kitchens' for brine boiling, as well as Terminal Classic residential structures at Ek Way Nal. The authors report the discovery of an earlier residential building alongside salt kitchens at the nearby site of Ta'ab Nuk Na. This finding indicates that surplus household production began during the Late Classic, …

Different Maternal Responses And Cognitions In Hypothetical Power Bouts: Relations To Parenting Styles, Kathy L. Ritchie

Midwest Social Sciences Journal

In order to explore how parental styles and maternal cognitions interacted with difficult extended discipline episodes called power bouts, 88 mothers were categorized as either Authoritative, Authoritarian, Permissive, or Uninvolved. Mothers then read six hypothetical vignettes about a 4-year-old child misbehaving and were asked how they would respond to the child and how they would respond a second time if the child did not behave. These open-ended responses were coded on a scale of increasing power assertiveness with 0 being giving in and 5 indicating using punishment through spanking, removal of privilege, or time out. Using Bell and Chapman’s (1986) …

Meteor Radar Vertical Wind Observation Biases And Mathematical Debiasing Strategies Including The 3dvar+Div Algorithm, Alan Z. Liu, Zishun Qiao, Gunter Stober, Alexander Kozlovsky, Ales Kuchar, Christoph Jacobi, Chris Meek, Diego Janches, Guiping Liu, Masaki Tsutsumi, Njål Gulbrandsen, Satonori Nozawa, Mark Lester, Evgenia Belova, Johan Kero, Nicholas Mitchell

Publications

Meteor radars have become widely used instruments to study atmospheric dynamics, particularly in the 70 to 110 km altitude region. These systems have been proven to provide reliable and continuous measurements of horizontal winds in the mesosphere and lower thermosphere. Recently, there have been many attempts to utilize specular and/or transverse scatter meteor measurements to estimate vertical winds and vertical wind variability. In this study we investigate potential biases in vertical wind estimation that are intrinsic to the meteor radar observation geometry and scattering mechanism, and we introduce a mathematical debiasing process to mitigate them. This process makes use of …

Interpreting Global Urban-Rural Political Divides: A Literature Review, Jobim Steyermark

Binghamton University Undergraduate Journal

Is the familiar urban-rural political divide a universal phenomenon, or is it conditional on institutional, cultural, or historical factors? In places where such a divide does exist, does it always manifest as a contest between progressive urban centers and conservative rural areas, or is this polarity sometimes reversed? Drawing on the insights of political scientists, sociologists, and historians, a review of the literature suggests resilient patterns of political geography that have their roots in the cleavage formation processes of the 19th and early 20th centuries. In particular, the legacy of agrarian politics and patterns of land tenure during this critical …

Shifting Geopolitics: Reimagining Globalization And Spatial Representation In The Post Covid-19 Era, Victoria H. Bergström

The Journal of International Relations, Peace Studies, and Development

Abstract: Since the emergence of the COVID-19 pandemic, the utilisation of maps has been at the forefront. Maps have informed policymakers, governments, and citizens of the distribution and spread of the disease. Although these maps have been used for various purposes, from border closures to curfews, there is an inherent danger in this widespread usage. Aside from the intricacy of these spatial representations, these widely distributed representations encourage isolationism and the reconception of borders in an increasingly globalised world. Furthermore, new connectivities through digital means have created a potential solution to international exchanges amidst physical limitations. Nevertheless, elitism prevents the …

The Geopolitics Of Infrastructuralized Platforms: The Case Of Alibaba, Hong Shen, Yujia He

Patterson School of Diplomacy and International Commerce Faculty Publications

Contemporary digital platforms have become increasingly infrastructuralized, and started to raise geopolitical tensions with their global expansion. Amidst the heightened geopolitical competition between the US and China, the growing power of Chinese infrastructuralized platforms has made them the center of recent geopolitical dynamics. Drawing from an exploratory case study, this paper discusses Alibaba, one of the most prominent Chinese Internet giants, as an infrastructuralized platform, and highlights its geopolitical struggles. Often perceived as an e-commerce company, Alibaba has become ‘infrastructuralized’: its now-massive digital empire has moved beyond e-commerce, expanding into almost every aspect of China’s and global digital economy such …

Effect Of Lateral Outflow On Three-Dimensional Flow Structure In A River Delta, M. Kifayath Chowdhury, Kory M. Konsoer, Matthew Hiatt

Faculty Publications

Spatial and temporal patterns in three-dimensional flow structure are linked to channel processes and morphology in many environments. However, there is not yet an understanding of how the flow structure is influenced by channelized and gradually distributed lateral outflows that are often prevalent in river deltas. This study presents an analysis of three-dimensional flow structure data collected from Wax Lake Delta, a naturally developing river-dominated delta in the northern Gulf of Mexico. Three hydrographic surveys were conducted using a boat-mounted acoustic Doppler current profiler at two sites: a channelized outflow zone and a distributary channel experiencing unchannelized lateral outflow. The …

Geography

Drought is a prominent feature of Hawaiʻi’s climate. However, it has been over 30 years since the last comprehensive meteorological drought analysis, and recent drying trends have emphasized the need to better understand drought dynamics and multi-sector effects in Hawaiʻi. Here, we provide a comprehensive synthesis of past drought effects in Hawaiʻi that we integrate with geospatial analysis of drought characteristics using a newly developed 100-year (1920–2019) gridded Standardized Precipitation Index (SPI) dataset. The synthesis examines past droughts classified into five categories: Meteorological, agricultural, hydrological, ecological, and socioeconomic drought. Results show that drought duration and magnitude have increased significantly, consistent …

Gis Analysis Of Housing Delinquency After Repeated Flooding In Horry County, South Carolina, Andrew White

Theses and Dissertations

How communities react and change after disaster has been well-studied in recent decades. Knowledge around time scales, spatial scales, and specific facets of the built environment, such as housing recovery, have all developed largely around the opportunities that disasters have provided in understanding societal functions. This research has given policy makers and institutions insights into shortcomings of disaster specific recoveries, but these shortcomings are generalized beyond the scope of the originally studied areas. This thesis adapts this body of knowledge to a GIS methodology to help localize understanding to the coastal South Carolina context of Horry County. This low-lying area …

Between Two Rivers: Environmental Justice And The Politics Of Ecological Improvement In Puget Sound, Grant M. Gutierrez

Dartmouth College Ph.D Dissertations

Environmental justice (EJ) has become a central framework for historically marginalized communities in the United States to identify unequal exposure to environmental harm. Yet, what once began as a radical social movement challenge to different forms of environmental racism has been taken-up by a wide swathe of civil society across diverse political, cultural, and ecological landscapes. In particular, river restoration efforts – and the many communities they implicate – are emerging as key sites of political-ecological interventions that are central to EJ. However, not all river restoration efforts employ EJ as a guiding framework. Through this dissertation, I ask: how …

Minimizing Surface Run-Off, Improving Underground Water Recharging, And On-Site Rain Harvesting In The Kathmandu Valley, Ambika P. Adhikari, Keshav Bhattarai

Himalayan Research Papers Archive

Nepal's political institutions and administrative units were thoroughly restructured in 2015 with the promulgation of the new Constitution. Several rural areas were combined to meet the definition of urban threshold criteria to classify rural areas into urban categories. Accordingly, over 3,900 local political and administrative units were amalgamated into 753 units, of which, 293 units are classified as urban. Within these newly defined urban areas, many natural environments have been converted into impervious surfaces such as paved roads, sidewalks, and building roofs. These impervious surfaces have drastically increased the amount of surface run-offs-often termed as "urban floods"--under increasing precipitation caused …
