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 …

Research Note: Did The Covid Pandemic Result In An Exodus Of The Latino Population Of New York City And The New York Metropolitan Region?, Laird W. Bergad

Center for Latin American, Caribbean, and Latino Studies

Data released by the U.S. Census Bureau’s American Community Survey 2021 One-Year samples indicate that despite the catastrophic health impact of COVID on the Latino population of the region, there was not a mass exodus of Latinos from the City or the metro area. The 2021 ACS One-Year samples, when compared with previous ACS One-Year samples, indicate that the City’s overall population increased by 0.5% between 2018 and 2021 and 1.3% between 2019 and 2021. The ‘Hispanic’ population, excluding Spaniards, rose by 0.2% between 2018 and 2021 and 1.4% between 2019 and 2021 according to these data.

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 …

Analyzing The Production And Use Of Fossil Fuels: A Case For Data Mining And Gis, Alejandro Conde

Geography and the Environment: Graduate Student Capstones

As technology progresses and data grows both larger and more complex, techniques are being developed to keep up with the exponential growth of information. The term “data mining” is a blanket term used to describe an approach to find anomalies and correlations in a large dataset. This approach involves leveraging data mining software to manipulate and prepare data, apply statistics to quantify trends and characteristics in the data from a high level, and potentially apply advanced techniques like machine learning to identify patterns that wouldn’t be apparent otherwise. In this case study, data mining aided a GIS in displaying substantial …

Event Scale Analysis Of Streamflow Response To Wildfire In Oregon, 2020, Will B. Long, Heejun Chang

Geography Faculty Publications and Presentations

Wildfire increases the magnitude of runoff in catchments, leading to the degradation of ecosystems, risk to infrastructure, and loss of life. The Labor Day Fires of 2020 provided an opportunity to compare multiple large and severe wildfires with the objective of determining potential changes to hydrologic processes in Oregon Cascades watersheds. Geographic information systems (GIS) were implemented to determine the total percentage burned and percentage of high burn severity class of six watersheds on the west slope of the Oregon Cascade Range. In addition, two control watersheds were included to contrast the influence of climatic effects. Spatial arrangements of burned …

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 …

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

Geography Faculty Publications and Presentations

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, …

Spatial And Age Disparities In Covid-19 Outcomes, Qian Huang

Theses and Dissertations

COVID-19 has caused significant social, economic, environmental, and political impacts globally and affected communities unequally in the U.S. The pandemic has also sparked interest in age-specific manifestations of infection, for example, studies confirmed the risk of increasing age with COVID-19 severity. However, the nonstationarity effects of health determinants among age groups have not been well examined. This study aims to explore the nonstationarity effects of social, behavioral, environmental, health care access, and political contexts on COVID-19 outcomes. This study poses three broad questions: 1) how did COVID-19 vaccinations align with COVID-19 daily cases and deaths in the United States; 2) …

Oki, Julian J. Reyes, Stephanie G. Yelenik, Clay Trauernicht

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 …
