Understanding and preventing police use of excessive force: An analysis of attitudes toward police job satisfaction and human rights laws. (open access)

Understanding and preventing police use of excessive force: An analysis of attitudes toward police job satisfaction and human rights laws.

Although governments try to create strict policies and regulations to prevent abuses, use of excessive force is still a problem for almost every country including Turkey. This study is intended to help Turkish National Police administrators to understand and prevent police use of excessive force. Studies on police brutality categorize three factors that explain why police officers use excessive force; these are individual, situational and organizational. In addition to brutality theories, job satisfaction literature is examined in this study to understand the use of excessive force. Job satisfaction is found to be related with burnout, turnover, stress, commitment, and performance. The impact of officers' attitude toward the criminal justice system and/or laws has not been tested widely. Police officers attitudes toward human rights laws are examined in this study to measure its impact on attitude toward use of excessive force. A secondary data collected in Turkey are analyzed by structural equation modeling which provides confirmatory factor analysis, path analysis, and causal relationships between variables. It is found that police officers' attitude toward human rights laws is a significant predictor of their attitudes toward use of excessive force. Job satisfaction and education level are the other significant variables affecting attitude toward …

The Influence of Giovanni Bottesini (1821-1889) on Pedro Valls (1869-1935): An Analysis of Homenaje à Bottesini (1906) by Pedro Valls (open access)

The Influence of Giovanni Bottesini (1821-1889) on Pedro Valls (1869-1935): An Analysis of Homenaje à Bottesini (1906) by Pedro Valls

This document traces a link between Pedro Valls and Giovanni Bottesini by identifying traits of Homenaje à Bottesini that resemble techniques and musical characteristics of Bottesini's music, through the comparison of Valls' Homenaje à Bottesini to Bottesini's Fantasia sur La Sonnambula, focusing on the works formal, musical and idiomatic characteristics. This is supported by documented evidence of Bottesini's presence in Spain during Valls's lifetime and Pedro Valls contact with the Italian master of the double bass school of playing and teaching method. This study also proposes adjustments in the notation of Homenaje à Bottesini to more modern and player-friendly score indications, which will help its inclusion into the active double bass repertoire. This document examines performance practice(s) of the work and what advantages or disadvantages these practices have in playing the work, and to ultimately offer a clear pathway, a road map, to performers interested in delving into Pedro Valls's work, with a better idea of what Valls's style consists of and what approach to take when performing his works.

A test of an etiological model: The development of disordered eating in Division-I university female gymnasts and swimmers/divers. (open access)

A test of an etiological model: The development of disordered eating in Division-I university female gymnasts and swimmers/divers.

Certain sport environments may contribute to the development of disordered eating and those that heavily emphasize weight and/or body shape can be particularly damaging to an athlete's body image, self-concept, and eating behaviors. In particular, female athletes in collegiate sports are at a greater risk for engaging in unhealthy behaviors because they face both societal pressures from Western culture to be thin, in addition to sport pressures that focus on performance and appearance. According to the American Medical Association almost half of American women are trying to lose weight, illustrating that societal pressures alone to be thin and attractive can influence the development of disordered eating. Athletes are exposed to the same sociocultural pressures as their nonathlete counterparts, and would be expected to have similar feelings about their bodies as women in general. Add subsequent pressures like team "weigh-ins," coaches' body comp preferences, judges' critiques, revealing attire, and endurance/strength demands, and the stage is set for the development of disordered eating. In the current study, participants were 414 Division-I female gymnasts, swimmers/divers, and they completed self-report measures assessing sport pressures, body satisfaction and disordered eating behavior to test Petrie & Greenleaf's etiological model. Results indicate that sport pressures do lead …

Teacher change: The effect of a professional development intervention on middle school mainstream teachers of English language learners. (open access)

Teacher change: The effect of a professional development intervention on middle school mainstream teachers of English language learners.

The purpose of this study was to investigate the effect of a professional development intervention conducted with mainstream middle school teachers of English language learners (ELLs) in a North Texas school district. Teacher change was examined in the context of this intervention. Three groups of teachers participated in this study. Group 1 (n= 4) consisted of teachers returning to the intervention for a second year. Group 2 (n= 12) consisted of teachers new to the intervention. Group 3 (n = 16) served as the control group and consisted of teachers who were not part of the intervention. Mixed methods were utilized, including a self-assessment questionnaire, an observation tool, and data from the Texas Assessment of Knowledge and Skills (TAKS) test. Statistically significant differences were found between teachers in Group 1 and teachers in Group 2 in the perception of self-efficacy. Statistically significant differences were also found for Group 1 and Group 2 teachers between the beginning and the end of the year. Group 3 teachers experienced a decrease in their perception of self-efficacy between the beginning and the end of the year. A statistically significant difference in the use of interaction was found across time for teachers in Group 1 …

Tsunami disaster response: A case analysis of the information society in Thailand. (open access)

Tsunami disaster response: A case analysis of the information society in Thailand.

The December 2004 Indian Ocean Tsunami wrecked thousands of lives, homes, and livelihoods - losses that could have been avoided with timely and better information. A resource such as information is needed at a fundamental level much like water, food, medicine, or shelter. This dissertation examines the development of the Thai information society, in terms of the share of information workforce and the level of diffusion of information and communication technologies (ICT), as well as, the role of the Thai information society in response to the tsunami disaster. The study combined the historical and political economy analyses in explaining factors influencing the growth of information workforce and the development of ICT in Thailand. Interviews conducted in 2007-08 revealed the Thai information society responded to the 2004 Tsunami - the first global internet-mediated natural disaster - in two areas: on-site assistance in collecting and recording identification information of tsunami disaster victims and on-line dissemination of disaster relief information. The effectiveness of ICT institutions in providing the tsunami disaster relief efforts and increasing the development of the information society were assessed using statistical procedures analyzing the perceptions of the Internet-based survey respondents. The disaster effects on survey respondents were also assessed. The …

An investigation into graph isomorphism based zero-knowledge proofs. (open access)

An investigation into graph isomorphism based zero-knowledge proofs.

Zero-knowledge proofs protocols are effective interactive methods to prove a node's identity without disclosing any additional information other than the veracity of the proof. They are implementable in several ways. In this thesis, I investigate the graph isomorphism based zero-knowledge proofs protocol. My experiments and analyses suggest that graph isomorphism can easily be solved for many types of graphs and hence is not an ideal solution for implementing ZKP.

Level Curves of the Angle Function of a Positive Definite Symmetric Matrix (open access)

Level Curves of the Angle Function of a Positive Definite Symmetric Matrix

Given a real N by N matrix A, write p(A) for the maximum angle by which A rotates any unit vector. Suppose that A and B are positive definite symmetric (PDS) N by N matrices. Then their Jordan product {A, B} := AB + BA is also symmetric, but not necessarily positive definite. If p(A) + p(B) is obtuse, then there exists a special orthogonal matrix S such that {A, SBS^(-1)} is indefinite. Of course, if A and B commute, then {A, B} is positive definite. Our work grows from the following question: if A and B are commuting positive definite symmetric matrices such that p(A) + p(B) is obtuse, what is the minimal p(S) such that {A, SBS^(-1)} indefinite? In this dissertation we will describe the level curves of the angle function mapping a unit vector x to the angle between x and Ax for a 3 by 3 PDS matrix A, and discuss their interaction with those of a second such matrix.

In vitro Cultures of Morus alba for Enhancing Production of Phytoestrogens (open access)

In vitro Cultures of Morus alba for Enhancing Production of Phytoestrogens

Plant estrogens have long been associated with health benefits. The potential of tissue culture techniques for the production of several secondary metabolites has been known for many years. Tissue cultures stimulate the production or induce the biosynthesis of novel compounds not found in the mature plant. Tissue culture of Morus alba, family Moraceae, is known to contain phytoestrogens, was established on plant-hormone supplemented Murashige and Skoog (MS) medium. Petiole and the stem tissue from mature trees were the best explants for initiation and proliferation of calli. The best callus proliferation was obtained on MS medium containing 1-napthalene acetic acid (1mg/ml) and benzylaminopurine (0.5mg/ml) for M. alba. Comparison of phytoestrogens of Moraceae species from in vivo and in vitro tissue isolation were carried out. The estrogenic activities of callus extracts were assayed in an estrogen-responsive yeast system expressing the human estrogen receptor alpha. Male callus extracts had higher estrogenic activity than male and female extracts from in vivo and in vitro tissues. Isolation and characterization of phytoestrogens from above tissues were carried out using solid phase extraction, high perfomance liquid chromatography and mass spectrometry techniques. Biochanin A, an isoflavonoid, was isolated as one of the compounds in male callus extracts. Biochanin …

A New N-way Reconfigurable Data Cache Architecture for Embedded Systems (open access)

A New N-way Reconfigurable Data Cache Architecture for Embedded Systems

Performance and power consumption are most important issues while designing embedded systems. Several studies have shown that cache memory consumes about 50% of the total power in these systems. Thus, the architecture of the cache governs both performance and power usage of embedded systems. A new N-way reconfigurable data cache is proposed especially for embedded systems. This thesis explores the issues and design considerations involved in designing a reconfigurable cache. The proposed reconfigurable data cache architecture can be configured as direct-mapped, two-way, or four-way set associative using a mode selector. The module has been designed and simulated in Xilinx ISE 9.1i and ModelSim SE 6.3e using the Verilog hardware description language.

Personal Properties: Stage Props and Self-Expression in British Drama, 1600-1707 (open access)

Personal Properties: Stage Props and Self-Expression in British Drama, 1600-1707

This dissertation examines the role of stage properties-props, slangily-in the construction and expression of characters' identities. Through readings of both canonical and non-canonical drama written between 1600 and 1707-for example, Thomas Middleton's The Revenger's Tragedy (1607), Edward Ravenscroft's adaptation of Titus Andronicus (1678), Aphra Behn's The Rover (1677), and William Wycherley's The Plain Dealer (1677)-I demonstrate how props mediate relationships between people. The control of a character's props often accords a person control of the character to whom the props belong. Props consequently make visual the relationships of power and subjugation that exist among characters. The severed body parts, bodies, miniature portraits, and containers of these plays are the mechanisms by which characters attempt to differentiate themselves from others. The characters deploy objects as proof of their identities-for example, when the women in Behn's Rover circulate miniatures of themselves-yet other characters must also interpret these objects. The props, and therefore the characters' identities, are at all times vulnerable to misinterpretation. Much as the props' meanings are often disputed, so too are characters' private identities often at odds with their public personae. The boundaries of selfhood that the characters wish to protect are made vulnerable by the objects that they use …

Negotiating Interests: Elizabeth Montagu's Political Collaborations with Edward Montagu; George, Lord Lyttelton; and William Pulteney, Lord Bath

This dissertation examines Elizabeth Robinson Montagu's relationships with three men: her husband, Edward Montagu; George Lyttelton, first baron Lyttelton; and William Pulteney, earl of Bath to show how these relationships were structured and how Elizabeth Montagu negotiated them in order to forward her own intellectual interests. Montagu's relationship with her husband Edward and her friendships with Lord Lyttelton and Lord Bath supplied her with important outlets for intellectual and political expression. Scholarly work on Montagu's friendships with other intellectual women has demonstrated how Montagu drew on the support of female friends in her literary ambitions, but at the same time, it has obscured her equally important male relationships. Without discounting the importance of female friendship to Montagu's intellectual life, this study demonstrates that Montagu's relationships with Bath, Lyttleton, and her husband were at least as important to her as those with women, and that her male friendships and relationships offered her entry into the political sphere. Elizabeth Montagu was greatly interested in the political debates of her day and she contributed to the political process in the various ways open to her as an elite woman and female intellectual. Within the context of these male friendships, Montagu had an opportunity …

Relationship between Fortune 500 companies with regulatory violations and/or criminal offenses and resulting stock values. (open access)

Relationship between Fortune 500 companies with regulatory violations and/or criminal offenses and resulting stock values.

The purpose of this study was to determine whether publicly disclosed violations by U.S corporations, resulting in convictions or settlements, erode shareholder investment in the offending organizations. This study was designed to assess whether or not the shareholders' reactions to corporations' violations were related to a decline in organizations' stock valuations across sectors. In addition, this study attempted to assess whether or not shareholder support, expressed by stock prices, declined more after a corporation was prosecuted or reached a settlement for violations, as compared to corporations that disclosed earnings disappointments. Also, this study investigated the stock prices of violating corporations compared to the non-offending corporations from within the same business sector, as well as considered the percentage decline for repeat offenders for violation two compared to violation one. Opposite to hypothesis, results showed that stock prices for the violating companies were significantly greater 12 months after the violation compared to the other months and no significant differences in percent decline between the eight sectors on any of the five decline measures. There were also no differences between violating companies and their matched companies. Companies with a violation had significantly greater stock prices overall than those without a violation.

The Five Dimensions of Professional Learning Communities in Improving Exemplary Texas Elementary Schools: A Descriptive Study (open access)

The Five Dimensions of Professional Learning Communities in Improving Exemplary Texas Elementary Schools: A Descriptive Study

This descriptive study investigated the development of the 5 dimensions of the professional learning community model in 5 economically disadvantaged and diverse Texas elementary schools, which demonstrated improvement in student achievement on the Texas Assessment of Knowledge and Skills (TAKS) over a 5-year period. Each of the schools were given the highest performance rating of Exemplary during the 2008 school year according to criteria developed by the Texas accountability system and had changed from an Acceptable rating in 2004. The purpose of this study was to determine the level of the development of the 5 dimensions of the professional learning community model in improving exemplary Texas elementary schools and to identify and compare the possible commonalities and differences existing between the schools on the 5 dimensions of professional learning communities. The 5 dimensions of the professional learning community model investigated in this study include: 1) shared and supportive leadership, 2) shared values and vision, 3) collective learning and the application of learning, 4) shared personal practice and 5) supportive conditions (collegial relationships and structures). The method used in this study was a mixed method approach that employed a questionnaire, individual principal and teacher interviews and school performance documents to collect …

No Title IX in Journalism: An Analysis of Subject Gender in Newspaper Sports Columns

The purpose of this study is to examine gender bias in sports media from the perspective of the sports columnist. The research analyzed 1,082 sports columns written by ten columnists (five male, five female) at newspapers across the United States. The columns were scrutinized to determine if the column subject was male or female. Results found that 84.4% of the sports columns were written about male athletes or men's sports compared to only 9% devoted to female athletes and women's sports. The research also found that female sports columnists write about female sports 12.7% of the time, while male sports columns only dedicate 6% of their columns to female athletes or women's sports. Newspapers with a larger circulation were more likely to have sports columns about female sports than were newspapers with smaller readerships. Six of the columnists were then interviewed to get their opinions on gender issues in sports journalism.

Interactions of equivalence and other behavioral relations: Simple successive discrimination training. (open access)

Interactions of equivalence and other behavioral relations: Simple successive discrimination training.

The experimenter asked if documented equivalence class membership would influence the development of shared discriminative stimulus function established through simple successive discrimination training. In Experiment 1, equivalence classes were established with two sets of 9 stimuli. Common stimulus functions were then trained within or across the equivalence classes. Greater acquisition rates of the simple discriminations with stimuli drawn from within the equivalence classes were observed. In Experiment 2, a third stimulus set was added with which no equivalence relations were explicitly trained. The findings of Experiment 1 were replicated, but the Set 3 results were inconsistent across subjects. The outcomes of the two experiments demonstrate that equivalence classes have an effect on other behavioral relations which requires further investigation.

An Evaluation of the Effects of Two Different Role Play Formats on the Outcomes of a Parent Training Curriculum

The current study was designed to replicate and extend previous research on the effectiveness of behavioral parent training. Specifically, the effectiveness of the Behavior Management and Parenting Services (BMAPS) curriculum in teaching parents to exhibit a set of parenting skills and respond accurately to a multiple choice examination about positive parenting techniques was evaluated. In addition, the curriculum was revised so that the relative effectiveness and acceptability of two role play formats could be assessed. The outcomes of the study showed an improvement in the participants' ability to identify correct answers on a multiple choice examination and apply the parenting skills taught in class within a role play format; results pertaining to the efficacy of each role play format were less conclusive.

State Level Causes of Terrorism: Limits on Political Expression (open access)

State Level Causes of Terrorism: Limits on Political Expression

Expanding on prior research into the state level causes of terrorism, I argue that state repression and limited state capacity reduces opportunities for non-violent political expression and increases the utility of terrorism. I also argue that economic freedom can is a form of political expression that can dissipate political grievances. While previous authors analyzed some of these variables separately using data on transnational attacks, I created a complete model incorporating the three categories of variables and tested my hypotheses using data that includes both domestic and transnational attacks. I use regression analysis for hypothesis testing and find support for the three primary contentions of this thesis and conclude that limits on political expression increase the likelihood nations will experienced increased levels of terrorism.

What has Damascus to do with Paris? A Comparative Analysis of Ibn Taymiyya and Gregory of Rimini: A Fourteenth Century and Late Medieval Rejection of the Use of Aristotelian Logic in the Legitimization of Divine Revelation in the Christian and Islamic Traditions

This thesis is a comparative analysis of Ibn Taymiyya of Damascus and Gregory of Rimini within their respective religious and philosophical traditions. Ibn Taymiyya and Gregory of Rimini rejected the use of Aristotelian logic in the valorization of divine revelation in Islam and Christianity respectively. The translation movements, in Baghdad and then in Toledo, ensured the transmission of Greek scientific and philosophical works to both the Islamic world during the 'Abbasid Caliphate and the Catholic Christian European milieu beginning in the eleventh century. By the fourteenth century both the Islamic and the Catholic European religious traditions had a long history of assimilating Aristotle's Organon. Ibn Taymiyya and Gregory of Rimini rejected the notion, adopted by the kalam and scholastic traditions respectively, that logical demonstration could be used to validate religious doctrine as taught in the Qur'an and the Bible. Ibn Taymiyya rejected demonstration completely but Gregory accepted its qualified use.
