The water-energy nexus is the dependent relationship between water and energy resources. The nexus results in complex policy and management challenges for resources that have been historically managed independently. This study quantifies electricity used for water service provision in Arizona. Employing the water use cycle as an analysis tool, this study divides municipal water use for the Tucson metropolitan area and city of Phoenix into four components. The findings suggest that energy intensity differences between Phoenix and Tucson exists due to geographic variables. The city of Phoenix and Tucson metropolitan area currently consume 1.2% of statewide electricity for water and wastewater service. Electricity demand for water and wastewater service in Tucson for 2008-2030 will be 110-131%, which is greater than the 85% electricity growth statewide. Water and wastewater agencies now face decisions regarding future plans to meet water demand and maintain a low overall energy use for service provision.

The Lissom project deals with the hardware-software co-design methodology. In this project, an integrated desktop environment for a design of multiprocessor systems on chip was developed. This environment can be used also for developing applications for multiprocessor systems. One part of the environment is a debugger that can be used to debug single core systems. In this thesis, a single processor debugger tool is described in detail and an extension to this tool is proposed and implemented based on the Nexus standard. The extended debugger allows debugging of multiprocessor systems.

The recent proliferation of jihadist incidents of terrorism in recent years has heightened interest in the modus operandi of terrorist operations. Available literature suggests a strong link between criminality and terrorism and the emergence of a crime-terror nexus. Current research on the nexus is based on dated examples and very rarely incorporates theory or an analytical lens. The purpose of this thesis is to explore modern manifestations of the crime-terror nexus from a social perspective in response to emerging data. The research reviews recent open-source data and literature at the institutional level, organisational level and the individual/social level. Analysis was approached from selected social and criminological angles including rational choice theory and a social psychological standpoint. Conclusions pointed to the increasing importance of social factors in areas such as radicalisation and group interactions to the processes of terrorism. Rather than attempting to explain causality, the study simply encourages the use of alternative perspectives when addressing the threat of terrorism. The thesis encourages academics and policy-makers to address the crime-terror nexus as a social problem that is fast becoming a national security threat. The research also highlights the importance of...

The thesis is analyzing relations between the Serb minority in Kosovo, Kosovo proper and Serbia from 2008 to 2013 by using Robert Brubaker's "Triadic Nexus" concept that defines a relation between a national minority, a nationalizing state and an external national homeland. The Triadic Nexus will be supplemented by David Smith's "Quadratic Nexus" concept with the addition of an international actor that would be the United Nations and the European Union. In the north and the southeast of Kosovo lives a huge Serb community that does not recognize Kosovo's independence since 2008. From 2008 to 2013 Kosovo authorities were trying to integrate Serb minority into Kosovo society, however in most cases unsuccessfully. Kosovo Serbs kept relations with Serbia, especially thanks to the existence of parallel Serb institutions in these parts of Kosovo. The position of the Serb minority in the Kosovo`s society is analyzed through the legal framework and their (non)integration into the administrative and political institutions of the Kosovo proper. This should provide hints if and how the Serb minority in Kosovo was or was not persecuted. The thesis further enlightens, through the analysis of the Serb minority`s integration in parallel Serb institutions, how big of a problem the parallel Serb institutions pose...

Energy and water resources share an important interdependency. Large quantities of energy are required to move, purify, heat, and pressurize water, while large volumes of water are necessary to extract primary energy, refine fuels, and generate electricity. This relationship, commonly referred to as the energy-water nexus, can introduce vulnerabilities to energy and water services when insufficient access to either resource inhibits access to the other. It also creates areas of opportunity, since water conservation can lead to energy conservation and energy conservation can reduce water demand. This dissertation analyzes both sides of the energy-water nexus by (1) quantifying the extent of the relationship between these two resources and (2) identifying strategies for synergistic conservation. It is organized into two prevailing themes: the energy consumed for water services and the water used in the power sector. In Chapter 2, a national assessment of United States' energy consumption for water services is described. This assessment is the first to quantify energy embedded in water at the national scale with a methodology that differentiates consistently between primary and secondary uses of energy for water. The analysis indicates that energy use in the residential, commercial, industrial, and power sectors for direct water and steam services was approximately 12.3 quadrillion BTU or 12.6% of 2010 annual primary energy consumption in the United States. Additional energy was used to generate steam for indirect process heating, space heating, and electricity generation. Chapter 3 explores the potential energy and emissions reductions that might follow regional shifts in residential water heating technologies. Results suggest that the scale of energy and emissions benefits derived from shifts in water heating technologies depends on regional characteristics such as climate, electricity generation mix, water use trends, and population demographics. The largest opportunities for energy and emissions reductions through changes in water heating approaches are in locations with carbon dioxide intensive electricity mixes; however, these are generally areas that are least likely to shift toward more environmentally advantageous devices. In Chapter 4, water withdrawal and consumption rates for 310 electric generation units in Texas are incorporated into a unit commitment and dispatch model of ERCOT to simulate water use at the grid scale for a baseline 2011 case. Then, the potential for water conservation in the power generation sector is explored. Results suggest that the power sector might be a viable target for cost-effective reductions in water withdrawals, but reductions in water consumption are more difficult and more expensive to target. / text

Although organizations and researchers have long pointed to the impact of migration on the development of countries of origin, one can hardly deny the bright spotlight and the rapid resurgence within policy debates, that the migration-development nexus enjoys over recent years. European politicians, inter-governmental organizations and academics alike un-equivocally point out that migration if managed appropriately, could bring the proverbial ‘win-win-win’ result for migrants themselves, sending, and receiving countries. So much so that, circular migration is being advocated as the solution to the migration challenges facing the European Union (EU) today. However, at a closer look, the evidence found is contradictory at best and largely depends on how development is defined and the breadth with which remittances are measured. Thus, this paper seeks for greater knowledge of this contemporary movement of persons, without which the EU will continue to develop policies and recommendations that may sat-isfy their member states, but not their intended audience. Starting with the Gastarbeiter programmes of the 1960-70s and concluding with the recent EU Blue Card initiative, this paper will conclude that the overall contribution of migrants to development is dependent on a scheme’s ability to a) encourage ‘return of innovation’ and b) broaden its outlook on non-financial remittances. Using the International Organization for Migration’s (IOM) Migration for Development in Africa (MIDA) Italy-Ghana/Senegal programme, and based on Ionescu’s four point criteria for successful circular migration policy, this paper will evaluate the MIDA Italy framework and suggest means by which its successes could be magnified.

archives@tulane.edu / Despite the work of dozens of dedicated scholars spanning decades, we seem no closer to a clear-cut answer as to who and what are signified by the signifier Creole in the Gulf South. And yet a perduring infatuation with this ever-enigmatic term continues to tempt scholars and laymen alike to try their hand at the Sisyphean task. It is hard to believe that such a vague label could possibly serve as a vehicle for ethnolinguistic identity, and yet that is precisely how Creole functions in Louisiana and beyond. This dissertation employs nexus analysis (Scollon and Scollon 2004) to explore the variable uses of Creole as a tool for delimiting ethnolinguistic boundaries in Texas and Louisiana. These boundaries can subsequently be interpreted as the basis for contemporary Creole identity in the Gulf South. The results bear on issues relating to cultural authenticity, linguistic legitimacy, and racial subjectivity. They also have implications for theories of migration, acculturation, and translocality. My data are drawn from interviews with a sample of Texas-resident (n=32) and Louisiana-resident (n=28) participants who self-identify as Creole-speaking Creoles. The main goal of the interviews was to give participants the space to define what Creole meant to them as a label for people and as a label for language. Based on these data, I was able to map the general and idiosyncratic characteristics associated with Creole in each place and make comparisons between the sub-samples. Creole ethnolinguistic identity, while internally diverse within the two sub-samples, displays very little variation between the sub-samples. These results indicate a certain, loose ideological coherence among Gulf South Creoles regarding delimitation via the label Creole. Creole ought to be considered a handy tool in an ethnolinguistic identity repertoire (cf. Benor 2010) whose contents include both linguistic and cultural traits. Such a reconceptualization may increase Creole access to voice in the region. The weight of translocal flows of people, products, and ideas that can be identified as Creole are heavily skewed towards originating in Louisiana. While Creole remains primarily associated with Louisiana, there are faint traces of Texas influence within and across the sub-samples. / 1 / Nathan A. Wendte
