An Empirical Examination of Service Dominant Logic: The Theory of the Network

Description: Marketing scholars question the ability of the 4Ps to explain higher order phenomena in modern marketing. Scholars contend that marketing's historical framework, based in product centric economic theory, constrains the 4Ps ability to form a foundation for a general theory of marketing. The focus on value embedded in product fails to explain knowledge-based intangible sources of competitive advantage. In response to this concern a new dominant logic for marketing called service-dominant logic (S… more

The Commander's Sword & the Executive's Pen: Presidential Success in Congress and the Use of Force.

Description: Post-force congressional rally effects are presented as a new incentive behind presidential decisions to use diversionary behavior. Using all key roll call votes in the House and Senate where the president has taken a position for the years 1948 to 1993, presidents are found to receive sharp decreases in both presidential support and success in Congress shortly after employing aggressive policies abroad. Evidence does suggest that presidents are able to capitalize on higher levels of congressio… more

Political Agenda-Setting in Cable News as a Possible Technique for Securing an Audience Niche

Description: In an effort to better understand the motivations behind perceived biases in the US cable news industry, 72 hours of CNN, FOX, and MSNBC during the week preceding the 2006 congressional election were analyzed. First- and second-level agenda-setting theories are used to examine how long and in what way federal politicians are portrayed. The results indicate distinct differences in political presentations between the three networks.

Psychological Abuse and Health: What Role Does Forgiveness Play?

Description: Existent literature suggests forgiveness could lead to either greater psychological abuse (reinforcement theory), or lower psychological abuse (interpersonal theory). Questionnaires were completed by 291 participants who were dating at least 2 months. More forgiveness-particularly Absence of Negativity-was related to less abuse received from their partner, and this effect was stronger for females than for males. Absence of Negativity (AN) was predictive of health variables (psychosomatic sympto… more

Split array and scalar data cache: A comprehensive study of data cache organization.

Description: Existing cache organization suffers from the inability to distinguish different types of localities, and non-selectively cache all data rather than making any attempt to take special advantage of the locality type. This causes unnecessary movement of data among the levels of the memory hierarchy and increases in miss ratio. In this dissertation I propose a split data cache architecture that will group memory accesses as scalar or array references according to their inherent locality and will su… more

Interpreting Richard Strauss's Der Krämerspiegel from the perspectives of the performers and the audience.

Description: The purpose of this document is to examine Richard Strauss's 1918 song cycle Der Krämerspiegel in order to discern compositional intent and to address problems performers may face in communicating the work to a contemporary audience. Examining the existing literature, it is never clearly stated why Strauss composed such an anomalous song cycle that defied aesthetic and generic norms of the day. The premise taken in this study is that Strauss, who was litigiously forced to write the work in orde… more

FPGA Implementations of Elliptic Curve Cryptography and Tate Pairing over Binary Field

Description: Elliptic curve cryptography (ECC) is an alternative to traditional techniques for public key cryptography. It offers smaller key size without sacrificing security level. Tate pairing is a bilinear map used in identity based cryptography schemes. In a typical elliptic curve cryptosystem, elliptic curve point multiplication is the most computationally expensive component. Similarly, Tate pairing is also quite computationally expensive. Therefore, it is more attractive to implement the ECC and Tat… more

Developing a Function-based Treatment for Problem Behavior Using a Structured Descriptive Assessment.

Description: This study evaluated the utility of structured descriptive assessment (SDA) to generate a hypothesis regarding the operant function of problem behavior when the analogue functional analysis (FA) failed to evoke problem behavior for an adult with developmental disabilities. The effectiveness of interventions based on that hypothesis was evaluated in the natural environment. The SDA succeeded in producing a relatively controlled baseline of problem behavior where the FA and direct observation cou… more

How componential factors and constraint enhance creativity in the development of new product ideas.

Description: New product ideation is the transformation of a raw idea into a robust concept with consideration of fit and feasibility of technologies, customer benefits, and market opportunity. Although the ideation process often involves ambiguous processes, it is the most critical activity in new product development (NPD). As a creativity task, the ideation process is considered heuristic rather than algorithmic. However, managing the ideation process as either a completely heuristic or an entirely algori… more

Influence of Sediment Exposure and Water Depth on Torpedograss Invasion of Lake Okeechobee, Florida

Description: Torpedograss (Panicum repens) was first observed in Lake Okeechobee in the 1970s and appears to have displaced an estimated 6,400 ha of native plants, such as spikerush (Eleocharis cellulosa), where inundation depths are often less than 50 cm. Two series of studies evaluated substrate exposure and water depth influences on torpedograss establishment and competitiveness. Results revealed that fragments remain buoyant for extended periods and so facilitate dispersal. Once anchored to exposed s… more
