The research involved the investigation of numerous sandy beaches across four sectors of the Algerian west coast: Tlemcen, Béni-Saf, Ain-Temouchent, and Oran. Between June 2019 and April 2020, a random collection of empty bivalve shells was …

Analysis Of Shoreline Change Along The Coast Of The Wadi Al Ma’Awil Watershed, Oman, Using The Digital Shoreline Analysis System, Amna Al-Ruheili

Journal of Agricultural and Marine Sciences

In an arid climate, lack of water constitutes a challenge. One solution can be to use storage dams as a tool to facilitate groundwater recharge and provide water for various uses. However, dams cannot be constructed without affecting the environment of the coastal shoreline and its ecological habitats. This study investigated the structural changes (i.e. accretion or erosion) of the coastline along the Wadi Ma’awil watershed. The Wadi Ma’awil watershed was dammed in 1991, providing a 10M m3 dam capacity. Satellite images were obtained for 1972, 1984, 1994, 2008, 2014, and 2018, and coastlines were digitized. For this research, we …

Old Ways In A Changing Space: The Issue Of Camel Pastoralism In Dhofar, Ali Tigani Elmahi

Journal of Agricultural and Marine Sciences

In the Arabian Peninsula, the Dhofar region is rich in camels. This national wealth has always been administered by traditional nomadic pastoral management, which must have evolved in Oman with the introduction of camels as domesticates in prehistoric times. In this region, camels have always depended on the free grazing system which is governed by tribal territoriality. Today, Dhofar is experiencing an extensive process of development. Land value has increased immensely, to the extent that it cannot be used for camel pastoralism. Furthermore, traditional camel management has always been directed to meet requirements of a subsistence economy. It has never …

Hematophagous Flies In Dhofar (Sultanate Of Oman): A Limiting Factor And A Potential Pathogenic Vector, Ali Tigani Elmahi

Journal of Agricultural and Marine Sciences

In Dhofar, pastoralists take certain precautionary measures against hematophagous flies: Haematobia minuta Bezzi, Musca crassirostris Stein and Forcipomyia (lasiohelea) whitcombei Boorman. Through their feeding on domesticated animals, these flies impede pasturing in certain areas during the rainy season (Khareef); hence they act as a limiting ecological factor and a custodian of the flora. The possibility that these flies could be potential pathogenic vectors has not been investigated in Oman, although in other parts of the world they are recognized as carriers of disease agents. The paper draws attention to this issue in Dhofar.

Transport Modeling Analysis To Test The Efficiency Of Fish Markets In Oman, Khamis S. Al-Abri, Hemesiri Kotagama, Andrew Palfreman, Houcine Boughanmi

Journal of Agricultural and Marine Sciences

Oman’s fish exports have shown an increasing trend while supplies to the domestic market have declined, despite increased domestic demand caused by population growth and income. This study hypothesized that declining fish supplies to domestic markets were due to inefficiency of the transport function of the fish marketing system in Oman. The hypothesis was tested by comparing the observed prices of several fish species at several markets with optimal prices. The optimal prices were estimated by the dual of a fish transport cost- minimizing linear programming model. Primary data on market prices and transportation costs and quantities transported were gathered …

Predicting The Distribution And Abundance Of Emperor Fishes (Lethrinus Spp.) In The Arabian Sea Using Two-Stage Generalized Additive Models And A Geographic Information System, Lubnah H. Al-Kharusi

Journal of Agricultural and Marine Sciences

The distribution and abundance of emperor fishes (Lethrinidae) along the Arabian Sea coast of Oman were analysed from commercial catch-per-unit-effort data for the periods 1996-2004 and 2005, respectively. Two-stage generalized additive models (GAM) were used to detect trends in abundance relative to environmental variables. The GAM that included month (positive in August and October), sea surface temperature (SST; positive at 25-27˚C) and longitude (positive between 57°50’ E-58°50’ E) explained the highly variable distribution and abundance patterns best. ArcGIS-9 was used as an auxiliary to visualize seasonal trends that could not be seen from the statistical GAM analysis. From the spatial …

Temporary Water Markets In Oman, Slim Zekri, Hemesiri Kotagama, Houcine Boughanmi

Journal of Agricultural and Marine Sciences

Market vis-à-vis command and control approaches have been widely adopted in natural resource and environmental management since the 1980s. Adoption of markets in managing irrigation water resources is also emerging. It has been argued that markets are ineffective in managing the demand for irrigation water due to very low price elasticity. Most studies have been based on mathematical models simulating water markets and not on observed prices and quantities in real water markets since such data are rarely available. In Oman, perhaps in response to the extreme scarcity of water, elaborate water demand management institutions emulating markets have evolved and …

The Curse Of El Dorado: How The Californnia Gold Rush Shaped The History Of Hawai'i, Ernesto Coronado

Theses and Dissertations

In the discourse of Western historiography, we fail to account for the importance of the Hawai’ian Islands. American imperialism did not stop with the occupation of the Pacific Coast but continued into the Pacific. In the mid-nineteenth century, Hawai’i and its monarch, King Kamehameha III, stood at the center of a dispute between Britain, France, and the United States. King Kamehameha III used the California Gold Rush and Hawai’i’s location to his advantage to garner capital and prevent the imperial powers from annexing his kingdom. However, even he knew he could not stop the mass wave of Hawai’ians leaving the …

Prenatal Exposure To Pm2.5 Concentration And Risk Of Preterm Birth In New Mexico; A Seasonal Pattern And Spatio-Temporal Modeling., Onyedikachi J. Okeke

Mathematics & Statistics ETDs

This study investigates the association between prenatal PM2.5 exposure and preterm birth risk in New Mexico (2014–2021). Using descriptive statistics, time series models, and spatial analyses, findings show an average preterm birth rate of 14.87 per 1,000 live births, with moderate correlation (r = 0.727) between PM2.5 levels and very preterm births. While traditional models revealed no significant global effect, spatial methods such as Geographically Weighted Regression (GWR) and Multiscale GWR uncovered strong spatial heterogeneity. PM2.5 effects varied by county (coefficients: -0.00154 to 0.00150), with clustering evident in 2018–2019 (Moran’s I = 0.155–0.174). Results highlight the limitations of global models …

Where’D You Go, Ohio: Progressive Ohio Ballot Initiative Passage In A Republican Aligned State, Colin D. Swearingen, Elizabeth Stiles, Barrett Scheatzle

The Journal of Economics and Politics

We investigate the effects of cosmopolitan and traditional county features on the opposition to three successful liberal state-wide initiatives on abortion and recreational marijuana using county-level data. Cosmopolitan/traditional variables include urban/rural living patterns, college graduates, average income and religiosity while control variables include turnout, poverty, race, region, and union support. We observe the results of these three elections to see the relationship between vote shares and factors such as income, education, rural/urban, and religiosity, controlling for other factors. Utilizing OLS and GAM regression models, our results provide support for our hypothesis that there is a relationship between cosmopolitanism and votes …

Violent Infrastructure: Natural And Unnatural Barriers To Climate Migration, Walden Hicks

Global Tides

This paper attempts to compare and contrast the impact of immigration policy on climate migrants in three Global North countries, Italy, the United States, and New Zealand. Climate migration will continue to be one of the most significant international concerns as global temperatures increase and previously habitable areas of the globe become uninhabitable. Climate migrants are forced to migrate for a variety of reasons due to climate change, including sea level rise, famine, rising temperatures, drought, and natural disaster. Global North countries must begin to transform their immigration systems towards climate justice and acceptance for climate migrants or communities will …

Old Habits Die Hard: How The Maine Indian Claims Settlement Act Perpetuates Settler Colonialism And Denies Indigenous Sovereignty, Brandon Dodds

Emory Law Journal Online

Around the time it was passed, the Maine Indian Claims Settlement Act of 1980 was considered by many to be a great victory for the Wabanaki Nations in Maine. But in the decades since, the Act has substantially hindered the Wabanaki Nations’ self-determination efforts. Frequent litigation between the Nations and the state of Maine, narrow interpretation by courts, and the state of Maine’s opposition to remedying the Act’s most harmful provisions have constrained the sovereignty of the Wabanaki Nations. As a result, the Wabanaki Nations have been largely excluded from the significant social, economic, and political gains that tribes throughout …

Background: Barriers to treatment with intravenous thrombolysis (IVT) for patients with acute ischemic stroke (AIS) in South Korea remain incompletely characterized. We analyze a nationwide prospective cohort to determine patient-level features associated with delayed presentation and non-treatment of potential IVT-eligible patients.

Methods: We identified consecutive patients with AIS from 01/2011 to 08/2023 from a multicenter and prospective acute stroke registry in Korea. Patients were defined as IVT candidates if they presented within 4.5 hours from the last known well, had no lab evidence of coagulopathy, and had National Institute of Health Stroke Scale (NIHSS) ≥ 4. Multivariable generalized linear mixed …

No. 39: Considering The Migration And Food Security Nexus In African Cities, Jonathan Crush, Zack Ahmed

Migration and Food Security (MiFOOD) Network

International migration and food security are still treated as separate policy and research domains, yet they are deeply intertwined in the African urban context. This paper unbundles the nexus between migration and urban food security by examining how migrants and refugees navigate food systems, cope with vulnerabilities, and deploy resilience strategies to mitigate food insecurity. As rapid urbanization reshapes African cities, migrants are becoming actors in informal food economies, both as consumers and vendors. However, economic exclusion, weak social protection, and precarity often expose them to heightened food insecurity. The paper explores how migrant food security is shaped by urban …

Migration and Food Security (MiFOOD) Network

While there is substantial literature on the effects of COVID-19 on formal businesses, limited evidence exists on the impacts of the pandemic on informal female-owned enterprises. Additionally, no studies have explored the role of post-pandemic recovery strategies in meeting the unique challenges experienced by the informal food vendors in secondary cities in the Global South. In this paper, we explore the impacts of COVID-19 and the post-pandemic recovery strategies on female informal food vendors in Kisumu, the third largest city in the western region of Kenya. The study adopted qualitative methods – in-depth and key informant interviews and focus group …

No. 37: Harnessing Diaspora Finance For Climate Resilience In Africa, Eunice Annan-Aggrey

Migration and Food Security (MiFOOD) Network

As climate change accelerates, the costs of adaptation are rising sharply. This escalation comes at a time when financial inflows to developing countries – such as official development assistance and foreign direct investment – are declining. Meanwhile, the global political climate is becoming unfavourable to sustained climate financing commitments. In this context, the role of remittances in supporting climate adaptation and mitigation in developing countries has attracted growing interest. This paper broadens the lens to examine diaspora finance more holistically, encompassing not only remittances but also diaspora investments and knowledge transfer. It explores the potential of these various diaspora finance …

School of Nursing and Midwifery

The development of immersive Extended Reality (XR) applications tailored for older adults remains a significant challenge, even amidst rapid technological advancements. Neglecting to account for the specific needs and requirements of endusers in the design process can result in reduced adoption rates or a total lack of engagement. We present findings and recommendations for building immersive experiences for older adults by exploring the similarities and differences encountered during the development of two immersive XR applications, with a specific focus on cultural heritage and underwater telepresence. The application development followed a monthly, iterative approach, integrating rapid prototyping for a total of …

Seasonal Effects Of Plant Functional Groups On Molecular Biogeochemistry Of Dissolved Organic Matter In Porewater Of A Poor Fen, Zhimin Song, Maryam Khaksari, Erik A. Lilleskov, Evan Kane, Paul V. Doskey

Michigan Tech Publications

Climate change may transform peatlands from net carbon (C) sinks to C sources, which could result in a positive feedback to global warming. Warmer temperatures might lower water tables, increase the abundance of shrubs, slow Sphagnum and sedge growth and further accelerate the decomposition of dissolved organic matter (DOM) with a concomitant release of C from the surface. Studies in which vascular plant functional groups (PFGs) in peatlands have been manipulated to mimic the potential effects of a warming climate on DOM are scarce. In the subject study, seasonal effects of PFGs on the molecular composition of DOM of peat …

The Landowner As Change Agent In Rural Modernization: An Ecuadorean Example, Gene N. Franckowiak

The Geographical Bulletin

In an era of impressive governmental and institutional support for rural modernization plans in developing countries, the privately financed, small-scale project can easily escape attention. A concentration of private funds and individual effort in small communities or single farms may occur for a variety of reasons ranging from humanitarian to pragmatic. Recognition may not be solicited if such gestures are designed to supplement existing law or correct difficult social problems in an environment of national political instability. Some landowners may react quite positively to highly localized problems to assure smoOlh functioning of agricultural systems where production is labor intensive. These …
