Title: CORRELATES OF OCCUPATIONAL SATISFACTION: INDICATORS FOR CURRICULUM EVALUATION AND REVISION OF A LAW ENFORCEMENT PROGRAM.
Creator: TUCKFIELD, JACK GILCHRIST., Florida Atlantic University, Buckner, Leroy M.
Abstract/Description: This ex post facto study was conducted (1) to determine if police officers attending an institution of higher education differed in their occupational interests from a criterion group of police officers and, (2) to determine if a pattern of academic interests could be identified from the curriculum of a specific community college and, (3) to determine if there were any differences in academic achievement between police officers who reflect a high occupational interest and police officers who...
Show moreThis ex post facto study was conducted (1) to determine if police officers attending an institution of higher education differed in their occupational interests from a criterion group of police officers and, (2) to determine if a pattern of academic interests could be identified from the curriculum of a specific community college and, (3) to determine if there were any differences in academic achievement between police officers who reflect a high occupational interest and police officers who reflect a low occupational interest. The sample consisted of 105 students who (1) had achieved an Associate of Arts degree from Miami-Dade Community College and, (2) were enrolled in the Criminal Justice baccalaureate program at Florida International University and, (3) were employed as a full-time, sworn, police officer with a law enforcement agency. Each subject completed a demographic data gathering form and a Strong-Campbell Interest Inventory, and official permanent record of grades (transcript) was obtained for each subject. The data from these instruments were processed using three statistical procedures to examine six null hypotheses relevant to the central question as to whether occupational interest would be reflected in academic achievement. The first statistical procedure was a test used to determine if the criterion group and the experimental group were from the same population. No significant difference was found between these groups which supported the use of the Strong-Campbell Interest Inventory as the major instrument used in this study. The second statistical procedure was a multiple regression using a Pearson Product Moment correlation which examined the relationships between the independent variable and the dependent variables. The independent variable was the scores achieved by the sample of the Police Officer Scale of the Strong-Campbell Interest Inventory while the dependent variables were (1) the cumulative grade point averages, (2) the grade point averages for the required general education courses, (3) the grade point averages for the elective courses and, (4) the grade point averages for the law enforcement courses. No significant relationships were found between these variables. The third statistical procedure, a multivariate analysis of variance, was a final attempt to glean further insights from the data. This analysis divided the sample into those who scored high on the Police Officer Scale and those who scored low on the same scale. Again, no significant differences were found. Therefore, since the criterion group and the experimental group are apparently from the same population and the multiple regression and correlation procedures do agree, it appears that the data, as presented, have no further secrets. Since it appears that this researcher anticipated a relationship that was not reflected in this study, there is a strong implication that the liberalization of elective choices fer students may have to be reconsidered. Further research in this area is encouraged using more variables and by examining the problem on a state-wide basis to control for possible regional or institutional biases.

The report presents the results of air and corrosion fatigue tests which are. interpreted in terms of time to failure, crack growth history, and fracture mechanics techniques. In addition, the results of cathodic protection of corrosion fatigue tests are interpreted in terms of simple-design criteria, as well as relative to Critical Corrosion Rate Theory. One of the more significant results presented is the greater longevity of corrosion fatigue, as compared to air fatigue, notched specimens stressed within 10-15 KSI above the air endurance limit. Also, the potential required to cathodically protect such notched specimens is shown to be 50 mV lower than for comparable smooth specimens. Both phenomena are attributed in part to the lowering of crack pH to acidic levels in notched specimens.

First stage zoeal forms were obtained and different foods, temperatures, and antibiotics were utilized in attempts to rear the larvae to metamorphosis. All three zoeal forms hatched with a large supply of yolk and molted within two hours of hatching. S. fritzmuelleri larvae were translucent with red chromatophores scattered over the carapace and abdominal somites. All three forms differed in size; S. fritzmuelleri was smallest and S. minus largest. S. minus died in the fourth stage, while both S. pectiniger and S. fritzmuelleri survived until the fifth stage. Pleopod buds were absent from all larval stages. All zoeae obtained were described, illustrated, and compared to each other.

It is shown that the articulatory parameters which cause allophonic variation in the native language (e.g. rate of breath release, vocal tract tension and coarticulation) are carried over into the pronunciation of the language being learned, and are major factors in producing a nonstandard accent.

Show moreThe exegetical method established by the early Christian Church fathers for interpreting the Bible, was of minor academic concern from 1865 until approximately forty years ago when the question was raised explicitly about its systematic application to medieval literature at large. A scholarly controversy over patristic exegesis developed and there was a growing number of publications dealing with the critical approaches to medieval literature and especially with the use of the patristic exegetical method for the understanding of specific works. These publications are surveyed in this paper and the method of patrist ic exegesis is illustrated through its application to three medieval poems. The conclusion reached indicates that the patristic exegetical method, though not the exclusive method applicable to medieval l i terature, has become an indispensable critical tool to enlarge our understanding of religious works and uncover significant meanings in works heretofore incompletely or erroneously understood.

Title: A CONTRASTIVE ANALYSIS OF THE CONCEPTS OF ASPECT IN THE VERB SYSTEMS OF ENGLISH AND SPANISH.
Creator: PRUCE, SUSAN MARILYN., Florida Atlantic University, Resnick, Melvyn C.
Abstract/Description: The Spanish verb is obligatorily inflected for aspect in the past tense: the speaker must indicate by his use of either a preterite or an imperfect form whether an action is perfective or imperfective. Because no such obligatory morphological distinction exists in English, the English-speaking student of Spanish may not always make the proper distinction between tense and aspect in the forms of the target language.

Show moreThe Spanish verb is obligatorily inflected for aspect in the past tense: the speaker must indicate by his use of either a preterite or an imperfect form whether an action is perfective or imperfective. Because no such obligatory morphological distinction exists in English, the English-speaking student of Spanish may not always make the proper distinction between tense and aspect in the forms of the target language. The problem, then, is to teach the student to express the aspect of any past verbal action so that he will be able to choose correctly between the preterite and the imperfect. A contrastive analysis of the role of aspect in all tenses of the verb systems of English and Spanish is presented for the purpose of ultimately formulating the best possible set of rules for differentiating between perfective and imperfective past actions.

Acanthurus coeruleus is a browser or strict herbivore, while A. bahianus and A. chirurgus are grazers, ingesting a variety of foods including plants, animals,. sediment, and detritus. The pharyngeal apparatus in the three species appears to be adapted for the type of food ingested. Ontogenetic changes in the length of the alimentary tract relative to standard length are greatest in the transforming acronurid stage; the acronurus appears to go through a non-feeding period during transformation. Juvenile A. coeruleus eat relatively greater amounts of filamentous algae than adults- which eat coarser plants. Juvenile A. bahianus and A. chirurgus ingest a larger quantity of organic detritus while adults eat more sedimentary particles. Competition for food is not evident; there is overlap in the abundant primary foods and variability in the secondary foods ingested.

Show moreThe nursing leader's challenging position in today's work environment may lead to an experience of stress, over-commitment, and overdoing. The purpose of this phenomenological study was to examine the meaning of caring for self by registered nurse leaders who had participated in a caring for self project in a community hospital setting. This group of 10 nursing leaders had participated in a caring for self project and had experience in nursing ranging from 18 to 32 years. One year after taking part in the caring for self project the 10 nursing leaders participated in individual taped interviews to explore the meaning of caring for self. Hermeneutic phenomenology (van Manen, 1990) was the method used for the interpretation of this research study. The depth of the lived experience of caring for self was described by each nursing leader. A metaphor of climbing a mountain to the peak of wisdom, being on the path and staying on the path regarding care of self, came from the words of the participants. In their words, the leaders communicate four common themes: Reflections on the Journey, Why Care for Self on the Journey, How to Care for Self on the Journey, and the Wisdom Learned Along the Path. Based on their reflections, recommendations include implementing creative ways to encourage care of self are for the hospital environment and educational methods to reinforce care of self for nurse leaders in the educational curriculum. A focus on care of self described by the leaders in this study may improve personal health, add to personal growth, assist in communication skills, allow for role modeling care of self to others, support setting priorities and boundaries, contribute to flexibility, and promote a work-life balance. These qualities would assist in creating a positive work environment and may influence the retention of nurses and contribute to recruiting new nursing leaders. Caring for self by nursing leaders is an important way for caring nursing theory to be brought to the practice setting. By role modeling a work-life balance nursing leaders bring the circle of caring out to others, beginning with care of self.

Show moreCase-based reasoning (CBR) is a powerful reasoning paradigm for many application domains like planning, diagnosis, classification, and decision making. Recognizing solutions of past instances which are similar to the problem in hand is the central concept of CBR. Accordingly, the main research issues in CBR are efficient indexing, retrieval, and evaluation of cases. Generalization of indices has been a major concern as it directly influences the size of casebases and the ability to recognize the right candidate cases. This dissertation work presents a novel indexing scheme--using fuzzy sets to represent case indices and fuzzy aggregation operators to evaluate case matches. The proposed scheme, REFIC (REasoning from Fuzzy Indexed Cases), provides a flexible and transparent scheme to generalize case indices leading to smaller casebases. A hierarchical aggregation of different index matches is suggested for case evaluation. Also, for continuous variable domains, it is proposed to combine the solutions of a small subset of best matching cases as opposed to the conventional approach of selecting and modifying a single best one. These schemes are demonstrated by implementing a case-based navigation planner for autonomous underwater vehicles (AUVs). This navigation planner comprises of an annotated map database, a case-based path planner, and a hybrid fuzzy-CBR based reactive navigation module. The annotated map database provides a general framework for modeling the navigational environment. Annotations attached to objects and geometrical query handling are two main features of this database. Using this system as a spatial casebase, an off-line path planning system for AUV missions is designed. The obstacle avoidance module employs CBR to dynamically select promising directions of movement and to activate a subset of navigational behaviors. This reactive navigation scheme has been found to be very robust under noisy sensor data and complex obstacle distribution patterns.

The Rootabaga Stories are an unusual expression of his talent but have, for the most part, escaped critical notice. Growing up in the Midwest and traveling by himself for several years provided a background that enabled him to imbue the stories with an American spirit. The stories collected by Jacob and Wilhelm Grimm, the literary tales of Hans Christian Andersen, and some American legends and folk tales combined to form the heritage Sandburg responded to in his creation of forty-nine stories. In fabricating the geography and culture of Rootabaga Country, Sandburg infused the stories with subtleties of language and attitude that are recognizably and exuberantly American.

The novel feature of this program is that it attempts to execute the maximum possible number of concurrent arithmetic operations in the L.P.C. algorithm. Each arithmetic operation is implemented by an active process which is the "task" construct in the Ada language. The computational part of the algorithm is implemented as a wavefront array of computing tasks. These computational arrays are driven by a driver task which coordinates the flow of data into and out of the computing surfaces. If the inter process communications time between tasks is small, then this model shows a potential for speed-up. If this be the case, one may conclude that this model is an appropriate implementation for a linear predictive coding.

Show moreAccompanying the potential increase in power offered by parallel computers is an increase in the complexity of program design, implementation, testing and maintenance. It is important to understand the logical complexity of parallel programs in order to support the development of concurrent software. Measures are needed to quantify the components of parallel software complexity and to establish a basis for comparison and analysis of parallel algorithms at various stages of development and implementation. A set of primitive complexity measures is proposed that collectively describe the total complexity of parallel programs. The total complexity is separated into four dimensions or components: requirements, sequential, parallel and communication. Each proposed primitive measure is classified under one of these four areas. Two additional possible dimensions, fault-tolerance and real-time, are discussed. The total complexity measure is expressed as a vector of dimensions; each component is defined as a vector of primitive metrics. The method of quantifying each primitive metric is explained in detail. Those primitive metrics that contribute to the parallel and communications complexity are exercised against ten published summation algorithms and programs, illustrating that architecture has a significant effect on the complexity of parallel programs--even if the same programming language is used. The memory organization and the processor interconnection scheme had no effect on the parallel component, but did affect the communication component. Programming style and language did not have a noticeable effect on either component. The proposed metrics are quantifiable, consistent, and useful in comparing parallel algorithms. Unlike existing parallel metrics, they are general and applicable to different languages, architectures, algorithms, paradigms, programming styles and stages of software development.

Show moreThis study investigates whether synchronous computer-mediated communication (CMC) has the potential to foster second language learners' strategic competence (as a component of communicative competence). For this purpose, the use of communication strategies (CSs) by 15 fourth-semester students of German during four computer-mediated and four oral "jigsaw" tasks is compared. The students used more CSs in oral interaction, which is attributed to a lesser degree of utterance planning in oral interaction and stronger time constraints in synchronous CMC. However, this quantitative difference is due to only five students' use of significantly more CSs in oral interaction. The distribution of the various CS types was similar in both communication modes; only code-switching occurred much more frequently in synchronous CMC, which is attributed to stronger time constraints in this medium and less monitoring by the instructor. Hence, synchronous CMC is not superior to oral interaction as far as promoting CS use is concerned.

Show moreThis study examined early adolescent perceptions of daily disagreements and negative interactions in relationships with mothers and fathers and their association with adolescent reports of self-esteem, self- and mother reports of behavior problems, and school grades. An I-States as Objects Analysis (ISOA: Bergman, 1998) identified seven distinct conflict patterns in parent-adolescent relationships: amiable, squabbling, discordant, hostile, labile, tranquil, and avoidant. These groups exhibited structural and interindividual stability, with groups characterized by constructive conflict processes demonstrating more stability than adolescents in groups characterized by non-constructive conflict processes. ISOA procedures failed to identify coherent adolescent adjustment groups. Person-oriented analyses indicated adolescents in the amiable, labile, and tranquil groups tended to have the best adjustment outcomes, followed by adolescents in the discordant and avoidant groups, with the worst adjustment outcomes reserved for adolescents in the squabbling and hostile groups. Variable-oriented analyses indicated that conflict rate and relationship negativity predicted concurrent and subsequent adolescent adjustment; behavior problems predicted concurrent and subsequent characteristics of parent-adolescent conflict. Person-oriented failed to reveal statistically significant associations involving change in parent-adolescent conflict and adolescent adjustment aver time. Variable-oriented analyses indicated adolescent adjustment predicted changes in parent-adolescent conflict variables more consistently than parent-adolescent conflict predicted changes in adolescent adjustment variables.

Show moreWireless ad hoc networks (or simply ad hoc networks) are infrastructureless multihop networks consisting of mobile or stationary wireless devices, which include mobile ad hoc networks (MANETs) and wireless sensor networks (WSNs). These networks are characterized by limited bandwidth and energy resources, frequent topology changes, and a lack of central control. These characteristics lead to the research challenges of ad hoc networks. The algorithms designed for ad hoc networks should be localized, selforganizing, and energy efficient. A connected dominating set (CDS) is frequently used in ad hoc networks as a virtual backbone to support efficient routing, service discovery, and area monitoring. In addition, efficient broadcasting (i.e., finding a small set of forward nodes to ensure full delivery) can be viewed as forming a CDS on-the-fly. The periodically maintained virtual backbone is called a static CDS, and the temporarily formed forward node set is called a dynamk CDS. For efficiency and robustness, the ideal CDS construction algorithm is lightweight, has fast convergence, and minimizes the CDS size. Recently, due to some specific applications and new techniques, the concept of a connected dominating set can be modified or further extended for more efficient usage. This dissertation focuses on the variations with applications of the connected dominating set, designing new concepts, and developing new algorithms for them. A review of CDS construction algorithms for ad hoc networks has been provided at the beginning. An efficient scheme, called Rule K, has been proposed for static CDS construction. Rule K achieves a probabilistic constant upper bound on the expected CDS size, which is currently the best known performance guarantee for localized CDS algorithms. Several CDS algorithms are extended to generate the extended CDS, which exploits the cooperative communication technique to further reduce the size of CDS. A k-coverage set is developed for higher robustness. With the equipment of directional antennas , the transmission can be restricted to some certain directions to reduce interference and energy consumption. The corresponding directional CDS is discussed. Finally, a wireless sensor and actor network (WSAN) is introduced and localized algorithms are designed for it.

Title: Concert fee determination: A game-theoretic approach.
Creator: Brooks, Arthur Charles., Florida Atlantic University, Stronge, William B., College of Business, Department of Economics
Abstract/Description: This thesis is in three parts. In the first, the cultural economics literature which concerns the labor market for musicians is reviewed and its major theoretical and empirical points are examined. The second part begins by briefly surveying the history and main topics in game theory, providing sufficient background for an understanding of the simplified Rubinstein-Stahl bargaining model, which is then described. The third part applies this model to the process by which concert fees are...
Show moreThis thesis is in three parts. In the first, the cultural economics literature which concerns the labor market for musicians is reviewed and its major theoretical and empirical points are examined. The second part begins by briefly surveying the history and main topics in game theory, providing sufficient background for an understanding of the simplified Rubinstein-Stahl bargaining model, which is then described. The third part applies this model to the process by which concert fees are settled upon, and leads to a number of conclusions. Among these are that subjective discount rates reflect bargaining power in the situation described, and that these discount rates are affected by the notorieties of the parties involved.

Title: Conjectural variations in models of the oligopoly.
Creator: Brown, Roger Joseph Jr., Florida Atlantic University, Hung, Chao-shun, College of Business, Department of Economics
Abstract/Description: This thesis reviews the contemporary work in the area of the role of conjectural variations on the equilibrium price and quantity, in models of the oligopolistic industry. Industry is shown to be capable of producing from the competitive output, to the monopolistic, depending on the conjectural variations of the industry members. Furthermore, it is shown that the results are independent of the number of firms within the industry, as opposed to the classic Cournot model of the oligopoly....
Show moreThis thesis reviews the contemporary work in the area of the role of conjectural variations on the equilibrium price and quantity, in models of the oligopolistic industry. Industry is shown to be capable of producing from the competitive output, to the monopolistic, depending on the conjectural variations of the industry members. Furthermore, it is shown that the results are independent of the number of firms within the industry, as opposed to the classic Cournot model of the oligopoly. Additionally, the notion of consistency of conjectures is reviewed, that is when firms' conjectures regarding their rivals are correct. The imposed requirement of consistency of conjectures is shown to result in a unique price-quantity solution. This latter unique solution is further investigated, by incorporating simple transport costs into the oligopoly model.
