Show moreThis exploratory study utilized qualitative methods to approach regional language abilities of local respondents and how it affects their regional identity. The theoretical framework of this study explored some of the tenets of symbolic interaction emphasizing on identity theory and how the flexible aspect of face-to-face interaction can define the self and someone's regional identity as it relates to their regional language use. Data for this study were collected in a small Occitan village in Southern France. In particular, the study explored the link between an individual residential setting, his/her age and his/her ability to speak the regional language. The results indicate that the ability to speak the specific regional or even sub regional language does not greatly affect an individual's regional identity, thus potentially contributing to the continuing decline of that language in the region. Furthermore, that future studies are merited to explore whether these results are specific or if they can more broadly be applied to other Occitan regions or elsewhere where regional languages are spoken.

Show moreThe Rhetoric of the Regional Image: Interpreting the Visual Products of Regional Planning investigates the manner in which visual conventions and visual contexts of regional visioning scenarios affect their interpretation by urban and regional planners, who use visual communication to meet the technical and rhetorical demands of their professional practice. The research assesses Central FloridaÃ‚Â's Ã‚Â"How Shall We Grow?Ã‚Â" regional land use scenario using focus groups and interviews with planning professionals, a corresponding survey of community values, and rhetorical analysis to explore the Ã‚Â"How Shall We Grow?Ã‚Â" scenario as persuasive communication. The Rhetoric of the Regional Image proposes specific recommendations for technology-based visual communication and scenario development in urban and regional planning practice, while contributing to literature in technical communication and rhetoric by examining plannersÃ‚Â' professional communication within their discourse community.

Show moreFraming is important for specification and verification of object-oriented programs.This dissertation develops the local reasoning approach for framing in the presence of data structures with unrestricted sharing and subtyping.It can verify shared data structures specified in a concise way by unifying fine-grained region logic and separation logic. Then the fine-grained region logic is extended to reason about subtyping.First, fine-grained region logic is adapted from region logic to express regions at the granularity of individual fields. Conditional region expressions are introduced; not only does this allow one to specify more precise frame conditions, it also has the ability to express footprints of separation logic assertions.Second, fine-grained region logic is generalized to a new logic called unified fine-grained region logic by allowing the logic to restrict the heap in which a program runs. This feature allows one to express specifications in separation logic.Third, both fine-grained region logic and separation logic can be encoded to unified fine-grained region logic. This result allows the proof system to reason about programs specified in both styles.Finally, fine-grained region logic is extended to reason about a programming language that is similar to Java. To reason about inheritance locally, a frame condition for behavioral subtyping is defined and proved sound.

Title: THE UNITED NATIONS FUND FOR POPULATION ACTIVITIES: CHANGING THE DIRECTION OF THE TOTAL FERTILITY RATE IN DEVELOPING NATIONS.
Creator: Fazecas, Michaela, ME Jungblut, Bernadette, University of Central Florida

Show moreThis thesis builds on previous United Nations' research investigating factors affecting the Total Fertility Rate (TFR) in six (6) states: Burkina Faso, Mexico, Morocco, Nepal, the Philippines, and Uganda. The present research, however, provides a broader assessment of the TFR and the potential causes of its decline by examining countries across nine (9) regions of the world – sub-Saharan Africa, Latin America, South Asia, East Asia, the Middle East and North Africa, the Caribbean, the Pacific Islands, Eastern and Southeastern Europe, and the former Soviet Socialist Republics of the Commonwealth of Independent States. The present analyses are also conducted over time, specifically from 1960 through 2002.Five (5) primary hypotheses regarding factors affecting the Total Fertility Rate are examined using feasible generalized least squares regression analysis. First, foreign debt is hypothesized to have a positive relationship to TFR. That is, holding all else constant, as foreign debt increases, TFR is expected to increase as well. Foreign debt is operationalized first, as total external debt; second, as long-term debt, and third, as total debt service as a percentage of exports of goods and services. Second, foreign aid, the level of socioeconomic development, and the extent of females' education are all hypothesized to have negative relationships to TFR. That is, all else constant, as foreign aid increases, TFR is expected to decrease. All else constant, as the level of socioeconomic development increases, TFR is also expected to decrease. All else constant, as the extent of females' education increases, TFR is also expected to decrease. Foreign aid is operationalized as first, International Bank for Reconstruction and Development (IBRD) loans and International Development Agency (IDA) credits; and second, as official development assistance and official aid. The level of socioeconomic development is operationalized as the Gross National Income (GNI) per capita in terms of purchasing power parity. The extent of females' education is operationalized as first, the adult female literacy rate (ages 15 and above), and second, as the ratio of young literate females to males (ages 15 – 24). Finally, whereas previous scholars have hypothesized that industrialization reduces TFR (the Western European "demographic transition" hypothesis), the present research proposes that this relationship may not hold in developing countries. This possibility is investigated by analyzing the relationships between TFR and first, the value added of agriculture (as a percentage of GDP); second, the value added of industry (also as a percentage of GDP); third, the value added of manufacturing as a percentage of GDP; and fourth, the value added of services as a percentage of GDP. The findings presented here suggest first, that the foreign debt and foreign aid have differing effects on TFR in different regions of the world. Second, the effects of socioeconomic development and females' education are more consistent (than foreign debt and foreign aid) across the different regions – but intriguing variations still exist. Finally, it appears that, with very few exceptions, the Western European-based demographic transition model does not hold for non-Western and developing areas. Therefore, new, region-specific models of TFR need to be developed – and public policy needs to be based on these more accurate, more context-appropriate models.

Show moreTo date, the use of mitochondrial DNA in forensic analysis has relied on the presence of variations in the control region to differentiate between samples. One problem that this analysis has shown is the occurrence of common Haplogroup H haplotypes or identical sequences. Thus, there is a need to enhance the distinguishing power of this type of analysis. One option has been to investigate the mitochondrial coding region for polymorphisms that could differentiate between samples with identical control region haplotypes. The goal of this study has been to identify polymorphic coding region sites for development in a Pyrosequencing assay that would effectively enhance the discriminatory power of mitochondrial DNA analysis. With this goal in mind, five duplexes have been successfully developed and tested, utilizing the ten polymorphic sites that had been selected, with most sites being specific to Caucasians. Validation studies were performed to test the durability of the assay. The specificity of the assay to primate and non-primate species was determined to be limited to primate species only. Sample variations, including mixtures, dilutions and environmental exposure, were utilized to assess the sensitivity of the Pyrosequencing method. It was found that a minimum initial DNA input of 10fg was necessary for reliable results. The Pyrosequencing assay was able to detect mixtures at a 1:1 ratio and environmental samples exposed to the elements from up to 1 week for blood and 6 weeks for semen. Samples designed to simulate typical casework materials were analyzed and found to provide for consistent results, including trace fingerprints and digested hair shafts. These validation results provide the conclusion that this assay is suitable for use in forensic casework and demonstrate that the mitochondrial coding region provides a viable alternative to hypervariable region analysis.

Show moreThe use of technology, such as electronic mail and the Internet, is becoming the norm in many workplaces. This is especially true in academic workplaces. The present study examined several issues related to electronic mail use and job satisfaction for employees within a higher education workplace. Results of the study found that administrative level employees both sent and received more email than non-administrative level staff. Job satisfaction was not found to be related to the amount of email sent or received. No difference in job satisfaction was found between employees at the main campus versus regional locations, nor was there a difference in job satisfaction between those employees who were supervised primarily via email and those who had in-person supervision. Results of this study help to clarify the role electronic mail plays in the workplace behavior and attitudes of higher education employees. This study also updates older research that found lower levels of job satisfaction in employees receiving e-supervision. The present study found no such differences, perhaps indicating a change in how employees experience e-supervision. Future researchers are urged to continue study examining how electronic technologies influence workplace attitudes and behaviors. While this study focused on email usage, other studies could examine Internet usage or focus on the integration of new technologies into the academic workplace.

Show moreWrong-way driving (WWD) has been problematic on United States highways for decades despite its rare occurrence. Since WWD crashes are rare, recent researchers have studied WWD non-crash events such as WWD 911 calls and WWD citations to understand the overall nature and trend of WWD. This paper demonstrates the regional nature of the WWD problem and proposes regional transportation systems management and operations (Regional TSM(&)O) solutions to combat this problem. Specifically, it was found that 11% of all WWD multi-data events (e.g., multiple 911 calls for the same WWD event) traveled from one county to another. Additionally, 30% of all WWD single-data and multi-data events occurred at or near interchanges between two limited access highways in counties with multiple operating agencies. This indicates that a significant proportion of WWD events could potentially travel from one limited access facility to another. Moreover, 28% of WWD events occurred on limited access facilities shared by multiple agencies. To emphasize the regional nature of WWD, this paper determined the vulnerable demographic groups in different regions of Florida by developing WWD crash and citation prediction models. The models' findings indicate that certain demographic groups (such as elderly or Hispanic) increase WWD risk. The models' results can be used to improve driver education and increase law enforcement presence in high risk WWD locations. Regional TSM(&)O solutions, such as coordination and communication among agencies and regional traffic management centers (RTMCs), law enforcement co-location with RTMCs, and strengthening statewide TSM(&)O programs to manage WWD events are also proposed.

Show moreResearchers and policy experts point to key issues and groups such as the Palestinian/Arab‐Israeli Conflict, the Muslim Brotherhood in Egypt, Saudi exported Wahhabism, and, in more recent times, the Iraq wars as being the source of militant Islam in this day in age. However, this perspective ignores key issues and ideals in to how this new form of Islam has emerged in recent decades. For instance, with all the conflicts that have occurred in recent decades, except for the 1979 Revolution in Iran, why have they not yielded Shari'a inspired Islamic states in Yemen, Lebanon, the Occupied Territories and Iraq? Currently the only Islamic states in the Arab world are ones that lay on the Persian Gulf that were established during their independence from colonial rule. One only has to look further east and to the north of the Middle East to see militant Islam taking hold in places like Chechnya, Tajikistan, Uzbekistan, Afghanistan, Waziristan and a host of other areas which do not get the attention from many people in the West. After the demise of the Soviet Union and the years directly after, a political vacuum was formed that received almost no attention from the outside world except for states with historical and cultural similarities. Here Islam has and is being used as a military and political doctrine to accomplish goals and as an ideological base for launching new attacks against its proclaimed enemies. Indeed many of the key theologians and figures have come from the Arab world, but the rise of militant Islam could not have formed with this alone. Many of the fighters on the ground in al‐Qaeda and its direct affiliated groups are indeed not Arabs but come from a wide range of different ethnic groups such as Afghans, Uzbeks, Tajiks, Uyghurs and Pakistanis who have answered bin Laden's call of lesser jihad against the West. Rather than examining militant Islam through a Middle Eastern perspective, this author wishes to give an alternate view that the current rise of militant Islam in the world is directly associated with the internal political situation of the Greater Caspian Sea Basin and not the Middle East as so many people have proposed in the past. To examine this idea, this author will look extensively at the internal conditions of states that have allowed militant Islam to arise and mature in such a short time span in this often forgotten region. The primary purpose of the proposed paper is to examine the rise of militant Islam through a Caspian Sea region lens rather than a Middle Eastern one. This study will also examine violent groups in various states to understand how groups are able to form and how they differ from each other. Countries ranging from as far as Turkey to the Xinxiang Province in China and from the southern reaches of the Russian Federation to Pakistan will be the primary focus.

Show moreThis thesis investigates the role of regional organizations in peacemaking and peacekeeping, particularly on the effects of peace agreement duration. This is important because the United Nations has been traditionally seen as the default international peacekeeping force but recently, more responsibility is being given to regional organizations.This study hypothesizes that regional organizations' ability to clear commitment problems, create specific agreements, and willingness to enforce agreements make them the most effective third parties to deal with many conflicts. However, the study also hypothesizes that regional organizations are less fit to mediate conflicts based around ethnicity, identity, or religious disparities.By utilizing a mixture of logistic regression and case studies, the results illustrate that regional organizations are an essential asset to creating agreements that elongate the duration of peace. In testing for the partiality of regional organizations, the specifics of agreements made, the willingness and capabilities of enforcement, the reason for the conflict and the institutionalization of the organization, quantitative and qualitative results illustrate that regional organizations are a valid tool for conflict management.

Show moreCoherent infrared radiation sources are essential for the operability of a wide range of scientific, industrial, military and commercial systems. The importance of the mid-infrared spectral region cannot be understated. Numerous molecules have some vibrational band in this range, allowing for identification of species by means of absorption, emission or some other form of spectroscopy. As such, spectroscopy alone has numerous applications ranging from industrial process control to disease diagnosis utilizing breath analysis. However, despite the discovery of the LASER in the 60s, to this day the amount of coherent sources in this range is limited. It is for this reason that the quantum cascade laser has gained such momentum over the past 23 years.Quantum Cascade LASERS (QCL) are semiconductor LASERS which are based on the principle of bandgap engineering. This incredible technique is a testament to the technological maturity of the semiconductor industry. It has been demonstrated that by having precise control of individual material composition (band gap control), thicknesses on the order of monolayers, and doping levels for each individual layer in a superlattice, we have unprecedented flexibility in designing a LASER or detector in the infrared. And although the technology has matured since it's discovery, there still remain fundamental limitations on device performance. In particular, active region overheating limits QCL performance in a high duty cycle mode of operation.In this dissertation, along with general discussion on the background of the QCL, we propose a solution of where by limiting the growth of the superlattice to a fraction of typical devices, we allow for reduction of the average superlattice temperature under full operational conditions. The consequences of this reduction are explored in theory, experiment and system level applications.

Show moreAncient populations across the globe successfully employed wetland agricultural techniques in a variety of environmentally and climatically diverse landscapes throughout prehistory. Within the Maya Lowlands, these agricultural features figure prominently in the region comprised of northern Belize and southern Quintana Roo, an area supporting low-outflow rivers, large lagoons, and numerous bajo (swamp) features. Along the banks of the Hondo and New Rivers, the Maya effectively utilized wetland agricultural practices from the Middle Preclassic to the Terminal Classic Periods (1000 B.C.(-)A.D. 950). A number of past archaeological projects have thoroughly examined the construction and impact of these swampland modifications. After four decades of study, a more precise picture has formed in relation to the roles that these ditched field systems played in the regional development of the area. However, a detailed record of the full spatial extent, combined construction costs, and potential agricultural productivity has not been attempted on a larger scale. This thesis highlights these avenues of interest through data obtained from high- and medium-resolution satellite imagery and manipulated through geographic information systems (GIS) technology. The research explores environmental factors and topographic elements dictating the distribution of such entities, the energetic involvement required to construct and maintain the systems, and the efficiency of wetland techniques as compared to traditional milpa agriculture. Spatial analyses reveal a total of 254 distinct wetland field systems within the 6560 square kilometer area of interest, clustered along navigable waterways, seasonal lagoons, and upland landscapes separating the Hondo and New Rivers. Energetic estimates illustrate substantial investment in wetland field construction, spanning several generations based on a locally available workforce. However, productivity calculations associated with the ditched field systems commonly exceed those attributed to milpa techniques, suggesting agricultural surplus far beyond the immediate need. These combined data indicate the potential export of maize and other agricultural commodities to regional centers in northern Belize and further abroad during the Late Preclassic and Late to Terminal Classic Periods through riverine trade networks. Additionally, these data help illustrate participation trends and patterns of connectivity relating to tiered sites within the area of interest. This research contributes to the overall understanding of wetland agriculture within Mesoamerica as well as provides insight into the political management of intensive agricultural production during Maya prehistory.

Using case studies of two major interventions by African regional organizations this thesis will determine what those tools may be. Both the intervention of ECOWAS into Liberia and the SADC into the DRC were rife with problems but they were able to bring some stability and even democracy to states in crisis. This thesis finds that African regional organizations can promote democracy and stability, but the focus is always on stability for the region. With strong institutions and mandates, policy agreement and strong leadership, African regional organizations can bring stability, development and even democracy to their regions.

Abstract / Description: Shock-tube experiments are typically performed at high temperatures (>1200K) due to test-time constraints. These test times are usually ~1 ms in duration and the source of this short, test-time constraint is loss of temperature due to heat transfer. At short test times, there is very little appreciable heat transfer between the hot gas and the cold walls of the shock tube and a high test temperature can be maintained.

Show moreShock-tube experiments are typically performed at high temperatures (>1200K) due to test-time constraints. These test times are usually ~1 ms in duration and the source of this short, test-time constraint is loss of temperature due to heat transfer. At short test times, there is very little appreciable heat transfer between the hot gas and the cold walls of the shock tube and a high test temperature can be maintained. However, some experiments are using lower temperatures (approx. 800K) to achieve ignition and require much longer test times (up to 15 ms) to fully study the chemical kinetics and combustion chemistry of a reaction in a shock-tube experiment. Using mathematical models, analysis was performed studying the effects of temperature, pressure, shock-tube inner diameter, and test-port location at various test times (from 1 – 20 ms) on temperature maintenance. Three models, each more complex than the previous, were used to simulate test conditions in the endwall region behind the reflected shock wave with Ar and N2 as bath gases. Temperature profile, thermal BL thickness, and other parametric results are presented herein. It was observed that higher temperatures and lower pressures contributed to a thicker thermal boundary layer, as did shrinking inner diameter. Thus it was found that a test case such as 800K and 50 atm in a 16.2-cm-diameter shock tube in Argon maintained thermal integrity much better than other cases – pronounced by a thermal boundary layer < 1 mm thick and an average temperature > 799.9 K from 1–20 ms.

Show moreUniversity of Central Florida College of Arts and Sciences Thesis; The development and birth of the Orange County Regional History Center is perhaps unlike any other local history museum in the United States. Its story is worth telling because of its long gestation, the difficulties in bringing this center to life, and the goals of the people who made it possible. All of these elements are a vital part of the history of Orange County, Florida and should not be overlooked. In this light, this thesis will discuss more fully three topics in relation to the creation of the new History Center. First, it will look at the American museum field and its role as a community-building enterprise in American society. Second, it will examine the history of Central Florida, a region that sorely lacks a strong sense of community. Third, it will trace the transformation of the Orange County Historical Society and Museum from a small volunteer-run museum into the Orange County Regional History Center, the largest history museum in Central Florida. The ultimate goal of the History Center is to foster a sense of community in a region with little feeling of connectedness. This community building goal has evolved from both a renewed emphasis on community service in the museum field, and the desire of the History Center's leaders and staff to serve more effectively the Central Florida region. My thesis tells the story of the history and development of the Regional History Center, an institution dedicated to bringing the diverse community of Central Florida together for discussion, dialogue, and reflection. It also identifies some of the new roles and functions it must assume in the future and the new tasks that await it as it strives to become more useful and relevant to its community. In that way, and through that resource, the institution can help build the foundation for a more promising future for present and future residents of Orange County.

This research sought to build on the existing research base through direct comparison of new urban and conventional suburban neighborhoods in central Florida, a region with an under-developed transit system and a climate that renders utilitarian physical activity impractical. Further, this research sought to lend greater insights into neighborhood selection factors across neighborhood types.(<)p(>)(<)p(>)A mixed-methods, single-case design was utilized to evaluate one new urban and one conventional suburban neighborhood in the central Florida region. Regional new urban neighborhoods were subjectively rated for adherence to tenets of the Charter of the New Urbanism, with the neighborhood (Celebration, in Osceola County, FL) found to most closely adhere to these tenets selected as the experimental group for the study. A socio-demographically comparable conventional suburban neighborhood (Sweetwater, in Seminole County, FL) was selected as the control group. Quantitative methods consisted of a household survey issued to 250 randomly- and convenience-sampled addresses in each neighborhood, followed by regression analysis to evaluate study hypotheses. Qualitative methods employed analysis of open-ended survey responses, detailed case studies of selected neighborhoods, and resident interviews. The household survey yielded net response rates of 15.79 percent and 25.50 percent for experimental and control neighborhoods, respectively, and a mean cross-neighborhood response rate of 20.64 percent. Twenty resident interviews (10 per neighborhood) were conducted. Quantitative and qualitative findings were compared to collectively address research questions.(<)p(>)(<)p(>)Regression results indicated no statistically significant difference between neighborhoods in attitudinal and behavioral components of community participation, in vehicle miles driven per week, or utilitarian physical activity frequency. However, results indicated that new urban residents had more positive attitudes toward utilitarian physical activity than conventional suburban residents and that attitudes toward community participation and utilitarian physical activity were positively correlated with associated behaviors. Qualitative findings provided substantial individual- and environmental-level insights to factors impacting evaluated attitudes and behaviors, and supported some quantitative findings while not aligning with others. Neighborhood selection factors were found to be quite different across neighborhoods: Celebration residents identified neighborhood social atmosphere and connection to the Walt Disney Company brand as top contributors to their selection decision, while Sweetwater residents expressed that access to quality schools was the most important factor in their selection decision. Qualitative findings indicated that car culture and climate within the central Florida region diminished both attitudinal and behavioral components of utilitarian physical activity across neighborhood types.(<)p(>)(<)p(>)This research expanded the understanding of the social and transportation outcomes of New Urbanism, particularly with respect to the central Florida region. While case and quantitative limitations may have impeded the ability of this study to draw decisive conclusions about research questions, distinctive themes regarding social and transportation outcomes were identified. Findings of this research supported those of some prior studies while contradicting others, indicating that further exploration is needed to establish a firm understanding of the capabilities of new urban development to achieve desired outcomes, and of regional characteristics that may influence these outcomes.

Title: The Effects of Narrative and Achievements on Learning in a 2D Platformer Video Game.
Creator: Fanfarelli, Joseph, McDaniel, Rudy, Smith, Peter, Bowers, Clint, Vie, Stephanie, University of Central Florida
Abstract / Description: Game design is a rigorous practice rife with complexity. The design of learning games is similarly complex to the design of their entertainment-based relatives. This complexity is partially due to the many interacting components that comprise games. The impacts of these individual components are not well understood.

Show moreGame design is a rigorous practice rife with complexity. The design of learning games is similarly complex to the design of their entertainment-based relatives. This complexity is partially due to the many interacting components that comprise games. The impacts of these individual components are not well understood. Advancing the understanding of how such component parts contribute to the formed game will inform decisions related to their inclusion and subsequent design within games. Achievements and narrative are two such components. They have been examined within gamified systems, but little research has studied them within the context of a serious game. The interactions between such elements and other game elements could produce results that diverge from the results of their use in isolation of a complete gaming framework. This dissertation selectively incorporates or excludes narrative and achievements within a two-dimensional platformer serious game to understand their impact on learning, flow, engagement, narrative transportation, and intrinsic motivation. Conditions are examined individually as well as in a combined condition. A control condition is maintained for comparison. Results indicate that narrative and achievements were not effective in improving the effectiveness of the game. Potential causes are discussed in tandem with the implications for the design and integration within a gaming framework. While the manipulations did not improve effectiveness, the game was responsible for substantially increased knowledge acquisition, as determined by pre and posttest results.

Title: PHILIPPINE ECONOMIC AND POLITICAL DEVELOPMENT AND PHILIPPINE MUSLIM UNREST.

Show moreMuslim culture and society has been a part of the Philippine islands in spite of nearly ninety-five percent of the population being Christian (a majority Catholic), yet did not become a separatist movement until the 1970's. Since then, the two main separatist groups the Moro National Liberation Front (MNLF) and the Moro Islamic Liberation Front (MILF) have been battling the Philippine government. The parties entered truces in 1996 and 2001, yet there has been a cycle of violence continues. The Abu Sayyaf Group (ASG), linked to Al Qaeda, emerged in 1990 and has launched many attacks on the Christian Philippine majority. The prolonged Muslim unrest in the ARMM has left thousands dead and hundreds of thousands displaced. The main objective of this research paper is to examine Philippine economic and political development and its impact on Philippine Muslim unrest. This paper presents a critical analysis of the economic and political development and Philippine Muslim unrest by examining six major features of the Philippines; they are: The historical evolution, economic development, political development, socio-cultural setting, geographic setting, and the quality of life of the Filipino people. This research also examines Fareed Zakaria's illiberal democracies theory, liberal institutionalism, and the Marxist theory of class revolution and primarily relies on research conducted at the University of the Philippines and from Philippine and Asian scholars. By taking a holistic comprehensive approach and by using international relations theory, this research fills two gaps in the literature about Philippine Muslim unrest. The research concludes with a look at future challenges, both short term and long term that face the country, as well as, possible future scenarios. The findings of this research are that the economic and political development and the historical evolution, though major contributory factors, are not the sole reason for the prolonged Philippine Muslim unrest. The most pervasive causal factor to Muslim unrest was the socio-cultural setting. Because of the all-pervasive nature of culture; at first glance, the socio-cultural setting was not a major apparent cause. At almost all times examined throughout this research, certain cultural tendencies guided decisions and altered the course of events more so than any other single variable. Corruption, crony capitalism, patrimonialism, and irrational institutions all stem from the tendencies of Philippine culture must be addressed to find lasting peace in the country. A move toward rational legal institutions and liberal constitutionalism, will lead the way to the creation of a liberal democracy and break the cycle of violence occurring in the Philippines.

Show moreTraffic safety has been considered one of the most important issues in the transportation field. With consistent efforts of transportation engineers, Federal, State and local government officials, both fatalities and fatality rates from road traffic crashes in the United States have steadily declined from 2006 to 2011.Nevertheless, fatalities from traffic crashes slightly increased in 2012 (NHTSA, 2013). We lost 33,561 lives from road traffic crashes in the year 2012, and the road traffic crashes are still one of the leading causes of deaths, according to the Centers for Disease Control and Prevention (CDC). In recent years, efforts to incorporate traffic safety into transportation planning has been made, which is termed as transportation safety planning (TSP). The Safe, Affordable, Flexible Efficient, Transportation Equity Act (-) A Legacy for Users (SAFETEA-LU), which is compliant with the United States Code, compels the United States Department of Transportation to consider traffic safety in the long-term transportation planning process. Although considerable macro-level studies have been conducted to facilitate the implementation of TSP, still there are critical limitations in macroscopic safety studies are required to be investigated and remedied. First, TAZ (Traffic Analysis Zone), which is most widely used in travel demand forecasting, has crucial shortcomings for macro-level safety modeling. Moreover, macro-level safety models have accuracy problem. The low prediction power of the model may be caused by crashes that occur near the boundaries of zones, high-level aggregation, and neglecting spatial autocorrelation.In this dissertation, several methodologies are proposed to alleviate these limitations in the macro-level safety research. TSAZ (Traffic Safety Analysis Zone) is developed as a new zonal system for the macroscopic safety analysis and nested structured modeling method is suggested to improve the model performance. Also, a multivariate statistical modeling method for multiple crash types is proposed in this dissertation. Besides, a novel screening methodology for integrating two levels is suggested. The integrated screening method is suggested to overcome shortcomings of zonal-level screening, since the zonal-level screening cannot take specific sites with high risks into consideration. It is expected that the integrated screening approach can provide a comprehensive perspective by balancing two aspects: macroscopic and microscopic approaches.

Show moreThe primary purpose of this study is to identify those people at most risk of being bullied at work. While much research is being conducted on school bullying, little has been conducted on workplace bullying. Using data gathered from a 2004 study conducted by the National Opinion Research Center for the General Social Survey, which included a Quality of Work Life (QWL) module for the National Institute for Occupational Safety and Health (NIOSH), linear regressions indicated significant findings. As predicted, workers in lower level occupations, as ranked by prestige scoring developed at National Opinion Research, are more likely to be victimized. Data also suggest that being young, Black, and relatively uneducated may contribute to being bullied in certain situations. Future research is needed to examine influences of socio-economic, legal, and other demographic factors that may predict the chance of being bullied.
