AbstractThis dissertation presents an extension of the warlord competition models found in Skaperdas (2002) and Konrad and Skaperdas (2012). I consider two non-parasitic warlords located on a line. Each warlord allocates resources for the extraction of natural resources, the production of goods and services, and conflict with the opposing warlord. Within the symmetric rates of seizure model, I use three different forms of the contest success function, a primary tool in the conflict theory literature, in my analysis. I show that the warlord closer to the point of conflict will invest less into the hiring of warriors and more into the production of goods and services, yet wins a larger proportion of total goods and services produced within the economy. Under certain conditions, the placement of the point of conflict at the midpoint between the two warlords maximizes the total resources toward war and minimizes total production. Under the asymmetric rates of seizure model, I find that the warlord closer to the point of conflict invests more in warfare and less in production; that is, results that counter what is found in the symmetric model.

Street Robbery Patterns: A Mixed Method Test of Situational Action Theory and Crime Pattern TheoryTaylor, Ralph B.; Groff, Elizabeth (Elizabeth R.); Wood, Jennifer, 1971- (Temple University. Libraries, 2020)According to current scholarship on offender decision making, choosing to rob another is based on a variety of individual and situational characteristics. Explanatory models often invoked within environmental criminology include routine activity, rational choice and crime pattern theories. Situational action theory’s suggestion that this decision depends, at least in part, on the interaction between offender criminal propensity and the setting’s moral context has yet to be examined. This investigation tests this idea by conducting structured interviews with active probationers and parolees centered on their decoding of streetscapes to clarify offenders’ perceptions of street robbery opportunities (Part I). These results inform an agent-based simulation contrasting the merits of assumptions made in the previously stated theories to learn how well each generates realistic concentrations of street robbery (Part II). Support emerges for both environmental criminology and situational action theory, but the results differed by the method employed. Implications follow for clarifying the theoretical processes driving these incidents and for promoting public safety.
The Formation, Performance, and Strategic Decisions of NonprofitsHamilton, Robert D. (Robert Devitt); Kumaraswamy, Arun; Mudambi, Ram, 1954-; Blau, Gary J. (Temple University. Libraries, 2012)This dissertation includes three essays about nonprofit organizations. The first essay investigates how the availability of financial and intellectual capital in the macro-environment influences the formation of nonprofit organizations. The analysis is an extension of Weisbrod's (1975) Heterogeneity Hypothesis and Ben-Ner and van Hoomissen's (1991) "social cohesion" principle. Findings indicate financial capital and intellectual capital are important to the formation of nonprofits, but the strength and direction of their influence varies by industry. The second essay applies Stakeholder Theory to predict the influence of board members, donors, and beneficiaries on nonprofits' performance. The study incorporates 134 charities from six different industries over a five year period and finds nonprofit performance is driven by the interests of the most salient stakeholders. Furthermore, the analysis indicates nonprofit stakeholders have the ability to control the behaviors of managers; behaviors which are not necessarily aligned with mission statements. No evidence, however, suggests salient stakeholders with shared interests collaborate for mutual benefit. Stakeholder Theory is also used in the third essay to predict the moderating role stakeholders fulfill in the relationship between environmental uncertainty and nonprofits' strategic decisions. The study incorporates the same database as the second essay and discovers the influence of environmental uncertainty on nonprofits' strategic decision depends on the ability of salient stakeholders to diversify their interests. The identified effect encourages Stakeholder Theory applications adopt a dual-perspective approach to the concept of salience; such applications need to account for the salience of the stakeholder to the organization and the salience of the organization to the stakeholder.

Quantum ESPRESSO is an integrated suite of open-source computer codes for quantum simulations of materials using state-of-the-art electronic-structure techniques, based on density-functional theory, density-functional perturbation theory, and many-body perturbation theory, within the plane-wave pseudopotential and projector-augmented-wave approaches. Quantum ESPRESSO owes its popularity to the wide variety of properties and processes it allows to simulate, to its performance on an increasingly broad array of hardware architectures, and to a community of researchers that rely on its capabilities as a core open-source development platform to implement their ideas. In this paper we describe recent extensions and improvements, covering new methodologies and property calculators, improved parallelization, code modularization, and extended interoperability both within the distribution and with external software.
