Domain Specific Analysis Of Privacy Practices And Concerns In The Mobile Application Market, Fahimeh Ebrahimi Meymand

LSU Doctoral Dissertations

Mobile applications (apps) constantly demand access to sensitive user information in exchange for more personalized services. These-mostly unjustified-data collection tactics have raised major privacy concerns among mobile app users. Existing research on mobile app privacy aims to identify these concerns, expose apps with malicious data collection practices, assess the quality of apps' privacy policies, and propose automated solutions for privacy leak detection and prevention. However, existing solutions are generic, frequently missing the contextual characteristics of different application domains. To address these limitations, in this dissertation, we study privacy in the app store at a domain level. Our objective is to …

Consumers And Eco-Labels: A Quantitative Analysis Of The Effects Of Various Sustainability Certification Models On Consumer Opinions, William F. Joseph

Senior Theses

This research consists of an econometric analysis of the efficacy of a privatized sustainability certification model versus a proposed government-endorsed sustainability certification model within the United Sates market. Today, the widely accepted model of sustainability certification is constituted by a large market of private certifiers. By analyzing the effects of the current model and alongside the effects of a hypothetical government-endorsed system on consumer preferences for sustainably produced goods, the thesis aims to motivate further discussion into the possible benefit of adopting a government-sponsored sustainability certification system. In general, analysis of the data suggests much more promising and significant effects …

Wishing For Water While Fleeing Their Farms: A Study Of Water Scarcity And Internal Migration In Tunisia, Tyler Rak

Independent Study Project (ISP) Collection

How does water scarcity and limited water access impact internal migration? I argue that water scarcity and limited access to water is likely to increase internal migration in Tunisia. The mechanism through which I will investigate this relationship is in the agricultural sector. In this research, I found that water scarcity does exist in Tunisia and that scarcity impacts the economy, employment, and perceptions of rural areas in Tunisia. This, in turn, likely contributes to internal migration, although my research could not conclude whether water scarcity acts a causative factor to internal migration. This topic has become more prevalent than …

The mantled howler monkey, Alouatta palliata, is one of the most commonly studied and widely distributed primate species in Central America. They have been reported to inhabit mangrove environments in Panama, but few studies have undertaken to describe their demography and behavior in these particular ecosystems. For my study, I spent 12 days studying A. palliata populations in both the mangrove and forested island ecosystems (Isla Parida and Isla Boca Brava) south of David. Seven groups were found in the mangrove environments, and 11 groups were found on the island environments. The mangrove groups were significantly smaller and at a …

Impact Of Wildlife Provisioning On Species Diversity, Relative Frequency, And Richness In New South Wales, Alanah Cohen-Tigör

Independent Study Project (ISP) Collection

Wildlife provisioning and camera trapping are two recently evolving methods of conservation and wildlife management, aimed at protecting animals in the face of ever worsening climate change. Habitats are being destroyed by climate disruption, decreasing species diversity and abundance worldwide. It is imperative that methods of protecting species are developed to slow or reverse this era of extinction. By providing supplementary food and water to ecological communities, the hope is that species will have improved survivorship and reproduction, making them more resilient and resistant to population decline. Camera trapping is product of modern technology, allowing researchers to monitor species without …

Computational Investigation Of Porphyrin-Based Host Design For Anions And Ion Pairs, Symphony Hill

Honors Theses

Little research has heretofore been devoted to studying the binding interactions between porphyrin-based molecular hosts and anions or ion pairs. Such interactions could be important in synthesizing molecules capable of detecting, binding, extracting, and transporting ions of biological, environmental, and industrial significance. With this in mind, computational studies of nine different porphyrin hosts were performed to examine the structural and binding properties of each molecule and potential ion guests. Using the Spartan computational chemistry software, each porphyrin was modeled and binding was tested with a number of ions of different shapes and sizes. Data was then collected regarding the distances …

Dairy & Development: An Investigation Into The Economic And Sociopolitical Dynamics Of Yak Cheesemaking In Nepal, Audrey Peiker

Independent Study Project (ISP) Collection

Cheesemaking in Nepal is full of love, passion, and creativity. What began as a Swiss development project in the 1950s has now grown into a full-fledged industry, providing jobs, creative outlets, and cultural expression for many. Nepal’s Dairy Development Corporation owns several factories throughout the country, setting the tone for the industry by establishing the standard price for milk and process for cheesemaking. From there, privately held factories innovate and compete, bringing new products to the market and increasing wages, but also struggle with consistency and reliability. Now, Nepal’s cheesemaking market is at a turning point—much of the herding population …

Ecological Living In Nepali Food Systems: A Synthesis Of Circular Nutrient And Knowledge Flows In The Kathmandu Valley, Kaitlyn Feely

Independent Study Project (ISP) Collection

Researching food-systems in Nepal can feel like drinking from a fire hydrant. Sixty-six percent of the population is directly involved in agriculture and a diverse set of ecocultural understandings influence the practice across the country’s landscapes, ranging from the Himalayas to urban centers to southern plains. In the Kathmandu Valley and peripheral hills where I conducted my research, seemingly any spare land was under cultivation, enabled by fertile ground, optimal climate, and market potential. But despite the prevalence of farming in daily life throughout the country, Nepal’s food system is not domestically self-sufficient. A complex web of imports and exports …
