Media Use, Interpersonal Communication, And Personal Relevance As External And Internal Representations Of Climate Change, Sonny Rosenthal, Pengya Ai
Research Collection College of Integrative Studies
Personal relevance is a key driver of individual climate action. It is also related to media use and interpersonal communication, which the current study examines from two perspectives. First, individuals may find climate change personally relevant because they experience it vicariously through the media and other information sources. Second, they may engage with climate change information because the issue is personally relevant. This study tested these models using structural equation modeling of online survey data from representative samples in Singapore (n = 1,997) and the United States (n = 2,009). Findings supported both models, albeit the first one more strongly. …

In this paper, we argue that contextual factors such as availability of infrastructure, socio-cultural characteristics of users, governance style, and the regulatory environment in global south cities creates opportunities for public and private sector actors to come up with innovative strategies to smart city development and the platformization of services. Despite different objectives, operationalization strategies, and expected outcomes between the public and private sectors, both sectors learn from one another to come up with innovative solutions for navigating contextual contingencies. Due to limited infrastructure and contextual diversities in global south cities, digital platforms require significant and specific forms of groundwork …

Long-Term Trend Of Summer Rainfall At Selected Stations In The Republic Of Korea, Il-Kon Kim, Rafique Ahmed
The Geographical Bulletin
The Republic of Korea (or South Korea) is located in the extreme northeastern region of the East Asian Monsoon climatic zone. Summer (June–September) is the rainy season in the country, which accounts for more than 60 percent of the annual precipitation. Using 50 years of summer (June–September) rainfall data (1951–2000) at 23 stations, this paper presents the geographic distribution of summer rainfall and its coefficient of variation in South Korea; and the long-term trend of summer rainfall at four selected stations. Summer rainfall in South Korea varies from less than 700 mm in the northeast to 800–900 mm or more …

Public-Private Partnerships In Tourism Development: An Analysis Of The Kuwait Experience, Obaid Al Otaibi
The Geographical Bulletin
Tourism and recreation has become one of the important and influential sectors in most of the modern economies. This sector has been accepted as one of the alternative sources of national income, employment, and foreign exchange. The state of Kuwait has many potentialities in tourism and recreation, and exploitation of this leads to more diversification of the economy besides augmenting its contribution to the GDP. Because Kuwait is an import oriented economy, it requires hard currencies (foreign exchange) to meet the import cost as well as to maintain stability in the international market. To compensate for the revenue fall stemmed …

When Wal-Mart Doesn’T Come To Town: Competitive Responses Of Established Retail Merchants In Edenton, North Carolina, Preston W. Mitchell, Derek H. Alderman, Jeffrey T. Webb, Dustin W. Stancil
The Geographical Bulletin
The study of retail geography is moving beyond an orthodox, spatial science tradition to include a consideration of the cultural and symbolic dimensions of retailing and consumption. This paper contributes to this emerging literature by exploring the cultural politics of retail change. The entry of a large format (or “big box”) retailer into a community is conceptualized as a socially contested process open to a variety of responses from local stakeholders. In the late 1990s, a coalition composed of elected officials, private citizens, and area business and property owners contested a possible plan to locate a Wal-Mart store in Edenton, …

Pioneer Migration To The Western Fringe Of Settlement:1837–1850, H. Jason Combs
The Geographical Bulletin
The Platte Purchase region did not become part of the state of Missouri until 1837. Prior to its annexation the area had been part of the territory reserved for Native American relocation. By 1850, the region had attracted over 40,000 pioneers from all areas of the globe. The majority of the early settlers followed the major river routes as they migrated west to the Platte region. The census data indicates that upon arrival many of these early pioneers clustered with other pioneers of similar heritage. As a result, there is a north-south settlement gradation present. Finally, the data highlights the …

No. 30: Pandemic Shocks And The Food Security Of Somali Migrants And Refugees In Nairobi, Kenya, Zack Ahmed, Jonathan Crush, Samuel Owuor
Migration and Food Security (MiFOOD) Network
The COVID-19 pandemic triggered severe shocks to food security for marginalized populations in urban areas. Somali migrants and refugees in Nairobi’s Eastleigh neighbourhood faced disproportionate impacts due to strict containment measures, disrupted food supply chains, and the shutdown of informal markets. These disruptions exacerbated existing socio-economic inequities, leading to heightened food insecurity. This paper examines the multi-dimensional effects of the pandemic on the food security of Somali migrants and refugees, focusing on their access to informal food networks and the broader socio-economic factors influencing their livelihoods. Utilizing a household survey and in-depth interviews conducted in August 2022, the study reveals …

Effects Of Longitudinal Training Walls On Two-Dimensional Flow Structure, Sediment Transport, And Bed Aggredation Using Numerical Methods And Sediment Core Analyses In Grand River, Michigan, Sumaiya Tul Siddique
LSU Doctoral Dissertations
Longitudinal training walls (LTWs) are structures oriented parallelly with the main flow and separate the channel into two sub-channels. One channel acts as the main navigational channel and the other is considered a secondary side channel. The long-term effects of the LTWs on morphodynamics and deposition remain poorly understood. This study investigated the long-term effects of the LTWs on flow, sediment transport and long-term deposition of the Grand River using numerical approaches and sediment core analysis. The effects of LTWs on 2D flow dynamics and sediment transport were investigated by using numerical approaches. The long-term deposition under the influence of …

Urban Street Systems In Nineteenth-Century Ohio Towns: An Analysis Of Diffusion, John M. Wegner
The Geographical Bulletin
This study considers the possible “migration” of urban street patterns associated with discrete east coast culture regions to America’s trans-Appalachian interior during the 19th century. Also examined was the possibility that these street patterns became less “culturallybound,“ or more admixed, over time. Ohio, one of the first (and most culturally diverse) trans-Appalachian states, was the focus of the study. To ascertain answers to the above questions, data pertaining to town platting throughout the state (as well as for four distinct survey regions associated with discrete east coast migration) was culled from county atlases and histories. Variables were selected so as …
