Executive Control of Craving: An Examination of College Students

Description: Previous research has shown that alcohol abuse may cause a deficit in frontal lobe functioning, specifically, areas of the frontal lobe that are related to executive function. Additionally, problems with executive function have been related to increased difficulty in managing cravings to addictive substances. The current study explored the relationship between alcohol use and performance on measures of executive functioning in a sample of 121 traditional college students. Students were given 5 measures of executive function designed to explore mental set shifting, updating, inhibition, sustained attention, and planning. These measures were used to examine the relationship between executive function and craving as measured by the Obsessive Compulsive Drinking Scale. Levels of alcohol use were also examined using the Alcohol Use Disorders Identification Test in relation to executive function performance and family history of alcohol abuse.

Executive Information Seeking and the Corporate Library

Description: This study began with an interest in corporate libraries and a genuine curiosity in the information preferences and resources valued by executive leaders at JET Aircraft Co. Executive information preferences and the downward trend in special libraries initiated the investigation of information seeking among executive leaders and yielded the inquiry: What resources do JET Aircraft Co. executives value when they need information? Employing an ethnographic approach, this study investigated what JET Aircraft Co. executives know about information resources, what they believe about information resources, and how they act when they require information. While JET Aircraft Co. maintained a special corporate library called the Company Research Library (CRL), the purpose of this study was to determine what resources were of value to executives at JET Aircraft Co., understanding that the CRL may or may not be a resource executives’ value. As a byproduct, this study also sought to establish executive information preferences and perceptions of the CRL. Information seeking at the executive level, studied through an ethnographic lens, provided insight into how executives at JET Aircraft Co. work and what they prefer, and it established a baseline for the Company Research Library’s position among the resources valued by executives.

Executive Participation in Innovation as a Function of Age and Tenure

Description: This study is designed to investigate the relationship between the age and tenure of the chief executive officer of a corporation and his participation in innovation. The chief executive is assumed to be the key participant in the innovation process. Two questions form the basis of the study, Firsts, are younger chief executives more innovative than older executives? And second, does the tenure of chief executives affect performance in innovation?

An exercise in story repair: A guided written disclosure protocol for fostering narrative completeness of traumatic memories.

Description: Flutists have reported musculoskeletal pain from practicing and performing their instrument. This study was a statistical approach to investigate potential causal risk factors for flute related pain among high school and college students. The study focused on the relationship between flute related pain and musical background or anthropometric measurements including size, strength and flexibility. Subjects included thirty high school and college-aged flutists who were assessed using a questionnaire, bi-lateral anthropometric measurements of the upper-extremities, upper-extremity performance tests for range of motion, isometric strength and rotation speed, and instrument specific questions. Four questions regarding pain associated with flute playing were treated as dependent variables and used for correlation and regression analyses with other independent variables. A six-factor regression model was created and each model was statistically significant. Results of this study show that strength, flexibility, pain spots, and exposure are risk factors for flute related pain. Both left and right pinch strength and right isometric pronation strength were significantly correlated to flutists experiencing pain while playing. Knowledge of these factors in relationship to pain is needed in flute pedagogy to help teachers and performers understand why flutists report pain during and after playing. Additional studies are warranted for replication of this study and for determining the clinical and pedagogical relevance of these findings.

Exercises for Preparing Singers to Perform Contemporary Choral Music

Description: This treatise has been prepared largely because of an increasing interest in contemporary music and an awareness on the part of many music educators of its merits in the curriculum of public schools and colleges. Since contemporary music is a controversial subject among directors, it has become necessary to search for specific, positive approaches to the teaching of contemporary music in high school.

Exhaustivity, continuity, and strong additivity in topological Riesz spaces.

Description: In this paper, exhaustivity, continuity, and strong additivity are studied in the setting of topological Riesz spaces. Of particular interest is the link between strong additivity and exhaustive elements of Dedekind s-complete Banach lattices. There is a strong connection between the Diestel-Faires Theorem and the Meyer-Nieberg Lemma in this setting. Also, embedding properties of Banach lattices are linked to the notion of strong additivity. The Meyer-Nieberg Lemma is extended to the setting of topological Riesz spaces and uniform absolute continuity and uniformly exhaustive elements are studied in this setting. Counterexamples are provided to show that the Vitali-Hahn-Saks Theorem and the Brooks-Jewett Theorem cannot be extended to submeasures or to the setting of Banach lattices.

Exhibit Eh: Canadian Dependency, U.S. Hegemony, and the Amorphousness of English Canadian Culture

Description: This thesis begins by examining the factors that have resulted in the dependent nature of Canada's political and economic structure, and proceeds to examine how this has contributed to the cultural amorphousness of English Canadian identity. The hegemonic authority of American and trans-national interests, established and maintained in the cultural sphere through the extensive monopoly of the distribution of cultural and media products, perpetuates the amorphousness of English Canadian culture through the appropriation of Canadian space by the international image industry. Such categorization of Canadian space reflects and perpetuates the imaginary representation of Canada within the dominant ideology as an indistinct and amorphous entity, and comes to usurp the materiality that constructs the lived identities of English Canadians.

Existence of a Sign-Changing Solution to a Superlinear Dirichlet Problem

Description: We study the existence, multiplicity, and nodal structure of solutions to a superlinear elliptic boundary value problem. Under specific hypotheses on the superlinearity, we show that there exist at least three nontrivial solutions. A pair of solutions are of one sign (positive and negative respectively), and the third solution changes sign exactly once. Our technique is variational, i.e., we study the critical points of the associated action functional to find solutions. First, we define a codimension 1 submanifold of a Sobolev space . This submanifold contains all weak solutions to our problem, and in our case, weak solutions are also classical solutions. We find nontrivial solutions which are local minimizers of our action functional restricted to various subsets of this submanifold. Additionally, if nondegenerate, the one-sign solutions are of Morse index 1 and the sign-changing solution has Morse index 2. We also establish that the action level of the sign-changing solution is bounded below by the sum of the two lesser levels of the one-sign solutions. Our results extend and complement the findings of Z. Q. Wang ([W]). We include a small sample of earlier works in the general area of superlinear elliptic boundary value problems.

Existence of an Alpha One-Adrenoceptor-Mediated Coronary Vasoconstrictor Reflex During Acute Systemic Hypoxia, in Anesthetized, Open-Chest Dogs

Description: The presence of an alpha-adrenoceptor--mediated coronary vasoconstrictor reflex during acute systemic hypoxia was examined in thirteen chloralose-anesthetized dogs. Local vasodilator effects were avoided by perfusing the left common coronary artery (LCC) with normoxic blood, while the dogs were ventilated with 5% 02-95% N2 . Left ventricular afterload was held constant and positive cardiac inotropic responses and beta two-adrenoceptor-mediated coronary vasodilation were blocked by propranolol. Parasympatheticmediated bradycardia and coronary vasodilation were blocked with atropine. Systemic hypoxia decreased LCC flow to normoxic myocardium by 19.4+2.6 %. Although myocardial oxygen extraction increased 9.7+2.9 %, myocardial oxygen consumption decreased 16.5+2.6 %. Intracoronary prazosin prevented the reflex vasoconstriction during repeated hypoxia.

An Existence Theorem for an Integral Equation

Description: The principal theorem of this thesis is a theorem by Peano on the existence of a solution to a certain integral equation. The two primary notions underlying this theorem are uniform convergence and equi-continuity. Theorems related to these two topics are proved in Chapter II. In Chapter III we state and prove a classical existence and uniqueness theorem for an integral equation. In Chapter IV we consider the approximation on certain functions by means of elementary expressions involving "bent line" functions. The last chapter, Chapter V, is the proof of the theorem by Peano mentioned above. Also included in this chapter is an example in which the integral equation has more than one solution. The first chapter sets forth basic definitions and theorems with which the reader should be acquainted.

The Existential Concepts of Time, Death and Choice in the Poetry of Philip Larkin

Description: This thesis examines time, death, and choice in Philip Larkin's poetry, arguing that his approach to these themes is not deterministic, but existential. The argument is based on the similarity between Larkin's views and those of three existential philosophers. Larkin's view of time, like Heidegger's, is that men live not in long stretches of time, but in processions of unconnected yet similar moments. A constant underlying sadness, like Kierkegaard's despair, makes each moment reminiscent of death. Like Sartre, Larkin finds meaning in his choices, and struggles to live authentically without expectation. Although Thomas Hardy influenced Larkin, given these similarities, Larkin's poetry cannot rightly be called deterministic. It is an attempt to preserve experience for its own sake.

The Existential Predicament as Theme in the Novels of Alberto Moravia

Description: The phrase "existential predicament" is a summary of Moravia's preoccupation as a novelist. In his fiction there is constant, unrelenting obsession with the situation of a single, particular character confronting, through his own existence in a physical, historical setting, the forces or powers of negation which threaten him with the frightening personal awareness of the possibility, even inevitability, of his own dissolution into nothingness.

Existentialism and Darwinism in The French Lieutenant's Woman

Description: Existentialism and Darwinism provide a means of viewing the development of personal freedom in a young English gentleman, Charles Smithson. Guided by Sarah Woodruff, a social outcast, Charles approaches freedom through the existential conditions of terror, anguish, and despair; he encounters alienation, human finitude, and the loss of a relationship with God on the way. The realization of his trapped state is aided by the Darwinian analogy present in the novel: the monied leisure class to which Charles belongs is presented as the species approaching extinction because it fails to make the changes necessary to survive changed conditions. The novel's two endings combine existential and Darwinian elements to present to Charles the choice that can help him escape his trapped state and gain freedom.

Exogenous Influences and Paths To Activism

Description: The focus of this research was to ascertain the indirect effects upon activism of intervening variables and recognized exogenous influences upon activism. In addition, this research also focused upon the differences and similarities of a recruited activist model and spontaneous activist model. Regression and path analysis were used to measure the direct and indirect effects of the exogenous and intervening variables. This research found that when the intervening variables, political interest, political awareness, exposure to media, altruism, and self-interest were introduced to both the recruited and spontaneous models, the direct effects of the variables were enhanced.

Exon/Intron Discrimination Using the Finite Induction Pattern Matching Technique

Description: DNA sequence analysis involves precise discrimination of two of the sequence's most important components: exons and introns. Exons encode the proteins that are responsible for almost all the functions in a living organism. Introns interrupt the sequence coding for a protein and must be removed from primary RNA transcripts before translation to protein can occur. A pattern recognition technique called Finite Induction (FI) is utilized to study the language of exons and introns. FI is especially suited for analyzing and classifying large amounts of data representing sequences of interest. It requires no biological information and employs no statistical functions. Finite Induction is applied to the exon and intron components of DNA by building a collection of rules based upon what it finds in the sequences it examines. It then attempts to match the known rule patterns with new rules formed as a result of analyzing a new sequence. A high number of matches predict a probable close relationship between the two sequences; a low number of matches signifies a large amount of difference between the two. This research demonstrates FI to be a viable tool for measurement when known patterns are available for the formation of rule sets.
