Journal of Sustainable Mining

The mining sector development is among the priorities of the Saudi Vision 2030. There is currently a lot of interest in the role of the mining sector in Saudi Arabia. This research contributes to this debate by empirically assessing the effects of mining on sustainable development in Saudi Arabia during the period 1980-2018. Unlike many previous studies, the three sustainable development dimensions, namely economic, social, and environmental, are jointly considered. The cointegration analysis, based on the ARDL, Gregory-Hansen, and combined cointegration tests, confirms the existence of long-run relationships between mining and all sustainable development dimensions.

Mapping Plastic Pollution In The Amite Watershed, Louisiana, Gourav Divan Jun 2021

Mapping Plastic Pollution In The Amite Watershed, Louisiana, Gourav Divan

LSU Master's Theses

Microplastics have quickly emerged as a concerning pollutant in both freshwater and marine environments. Their recent discovery means that their impacts are still being studied, however, it is important to continuously monitor their concentrations. An important conduit of plastic pollution to marine environments are rivers and streams. Previous models have estimated the transport of plastics from land to sea in many parts of the world. Most of these models, however, have been conducted at coarse spatial resolutions that make it difficult to establish tractable management programs to minimize this impact. Here, a previously existing model was applied to model for …

Engineered Nanostructured Nitrogen-Doped Carbon Network (Ndc) Electrodes With Unprecedented Cycling Stability For Water Capacitive Deionization In Harsh Conditions, Soha Essam Anwar Jun 2021

Engineered Nanostructured Nitrogen-Doped Carbon Network (Ndc) Electrodes With Unprecedented Cycling Stability For Water Capacitive Deionization In Harsh Conditions, Soha Essam Anwar

Theses and Dissertations

Capacitive deionization (CDI) is a feasible low-cost desalination technique for low-to-medium (brackish) salinity water. However, cycling stability and regeneration of the CDI electrodes are the bottlenecks hindering the practical application of the technology on large scale. Oxidation of the electrodes during the sequential adsorption-desorption processes is one of the most challenging problems hindering their long-term cycling performance. Herein, we demonstrated the ability to design and fabricate exceptionally stable CDI electrodes via a one-pot pyrolysis protocol. The optimized pyrolysis of nitrogen-carbon precursors at different temperatures enabled the fabrication of carbon materials with a controlled amount nitrogen dopant (NDCs) with exceptional cycling …


How State Interventions Affect Municipalities Taking The Lead In Sustainability, Jayce L. Farmer, Andres J.Rodriguez Lombeida Jun 2021

How State Interventions Affect Municipalities Taking The Lead In Sustainability, Jayce L. Farmer, Andres J.Rodriguez Lombeida

Public Policy and Leadership Faculty Research

The state and local governments throughout the United States interact within a complex system of multilevel governance to advance sustainability. However, we know little about what this hierarchical system of exchanges means for municipalities as they work to achieve energy efficient government operations. Drawing on a perspective of “contested federalism”, we examine how the transaction costs of state–local government relations affect the efforts of U.S. cities to lead by example and promote sustainability within their internal processes. We apply a Bayesian item response theory approach to assess the effects of state-level fiscal and policy interventions on municipal commitments to energy …

The fate of doxycycline (DC), a second generation tetracycline antibiotic, in the environment has drawn increasing attention in recent years due to its wide usage. Little is known about the biodegradability of DC in the environment. The objective of this study was to characterize the biotransformation of DC by pure bacterial strains with respect to reaction kinetics under different environmental conditions and biotransformation products. Two bacterial strains, Brevundimonas naejangsanensis DD1 and Sphingobacterium mizutaii DD2, were isolated from chicken litter and characterized for their biotransformation capability of DC.

For many Americans, the American Dream is a dream deferred. Recently, there has been an explosion in demand for diversity, equity, and inclusion in financial services. This has coincided with an explosion of a different kind related to delivering financial services through innovations in technology, otherwise known as FinTech. We have seen a plethora of FinTech applications on our smartphones, ranging from online lending to remote deposit making. While these applications provide potential opportunities to level the playing field for those whose dream has been deferred, there remain challenges.

An Analysis Of The Impacts Of Climate Change On Food Security In The Albertine Rift Of East Africa, Malcolm Jacob Jun 2021

An Analysis Of The Impacts Of Climate Change On Food Security In The Albertine Rift Of East Africa, Malcolm Jacob

Sustainability and Social Justice

As one of the most densely populated regions on the continent of Africa, the Albertine Rift (consisting of parts of Rwanda, Uganda, and the eastern DRC) faces ongoing problems providing enough food for its people through crop production, livestock husbandry, and other forms of food production. Even more troubling for the future is that anthropogenic climate change is expected to significantly exacerbate food insecurity. This paper addresses one central question: how will climate change impact food security in the Albertine Rift? Based on an analysis of available data, this paper finds that policymakers should listen closely to local farmers and …


My Sustainability Journey, Katelyn Adams Jun 2021

My Sustainability Journey, Katelyn Adams

Student Research

During my first year seminar, the class discussed some of the greatest issues humanity faces today and how we may have a part in a movement towards change. Much of what we discussed made connections between the treatment of the earth and current ethical dilemmas. Divisions among groups, shortcoming awareness of the importance of systematic change, destructive use of human and natural resources have allowed for the continued deprivation of the resources that the earth intends all living things to have access to. Issues arise when individuals and businesses diverge from their moral principles, or simply lack them, and view …
