L'emploi variable des signes diacritiques dans le français tchaté : une étude variationniste en temps apparent .
After providing an historical overview of the French spelling system and orthographic variation, this study analyzes selected internal (i.e., linguistic) factors and one external (i.e., social) factor that can influence the use of diacritics in online French-language chat sessions. From a corpus of synchronous computer-mediated communication, 3,855 tokens of graphemes capable of bearing diacritics were coded with the following scheme: Letter, Diacritic, Grapheme (i.e., Letter and Diacritic combined), Date of Participation, and Age Group of Participant. A multivariate (VARBRUL) analysis determined that Grapheme exerts the most influence on variation.

Employee empowerment: Relationships between location in the hierarchy, span of control, and industry type on perceptions of empowerment.
Access: Use of this item is restricted to the UNT Community.
The current study seeks to examine the relationships between perceptions of employee empowerment and perceptions of leadership, span of control, and industry type. Participants were gathered from an archival source employing a high school alumni e-mail group (n = 361) and a survey from 9 organizations (n = 647) and combined into a larger sample (n = 1008). The participants took Bodner's (2005) Assessment of Employee Empowerment and Assessment of Empowering Leadership instruments. Support was found to suggest that people report being less empowered than they believe that top management would report about them. Also, participants reported that their leader was less empowering than they believed top management would report about the leader. Span of control was found to impact perceptions of empowerment. Production workers reported feeling more empowered than workers in service industries. Participants did not report that leaders were more empowering if they were higher in the hierarchy (executive) than lower levels (coach, employee). Also, a respondent's position did not affect the relationship between job type and feelings of empowerment. This study suggests that the organizational design (span of control) and industry type may affect empowerment initiatives, while lower levels of the organization may view empowerment much differently than top management.
Employee Engagement: The Impact of Spiritual, Mental, Emotional and Physical Elements on the Relationship between Employee Engagement and Behavioral Outcomes
Data were collected by an external company for a healthcare service firm interested in learning the job-related attitudes of their employees. Thus, archival data from 1,287 employees were collected for a different purpose. The survey consisted of 117 questions covering a broad range of constructs. Consequently, the items were used to derive effective measures of employee engagement and behavioral outcomes, as well as the emotional, mental, spiritual and physical dimensions. Exploratory and confirmatory factor analysis procedures were used to create scales reflecting these four factors. Interestingly, six scales emerged, logically linking to and further specifying the initial dimensions. These were Organizational Linkage, Manager Relationship, Job Fit, Job Clarity, Work Pressure, and Meaningful Work. To test the hypotheses, six separate regression equations were calculated, which statistically supported modification by each of the dimensions. However, statistical significance of the interactions resulted from having a large sample, given the actual association was too small to be meaningful (e.g., a contribution of 0.6% of the variance). As each of the dimensions had a main effect on the behavioral measure during hypothesis testing, exploratory regression equations were calculated to further understand the interrelationships. Of most interest was finding that in the presence of Engagement, the main effects of only Organizational Linkage and Job Fit reached significance. However, when Engagement was not included, four of the six dimensions made a significant contribution to Behavioral Outcomes. Overall, there was support for previous conceptualizations. From the scientist-practitioner perspective, the six factors identified in this study may be more useful than the four initially proposed. The distinctions give practitioners additional information to use in interventions to improve employee behavior and retention.

The Employment Act of 1946: Original Intent Versus Current Interpretation, The Forces Underlying the Modification and the Implications thereof
There appears to be a vacillation from the original intent of the Employment Act of 1946. It was originally intended to serve as a tool whereby the smoothing and the easing of cyclical fluctuations of the business cycle could be facilitated. It now seems as though this tool has become one which is being used to correct those structural weaknesses which exist in the economy.

Employment Interventions for Consumers with HIV/AIDS
A systematic review of studies pertaining to employment interventions for consumers with HIV/AIDS was conducted in order to ascertain what programs and services have resulted in employment for people in this population. Research shows that programs specifically designed for individuals with HIV/AIDS have been beneficial for this population in regards to obtaining employment. This study discusses four employment interventions for people with HIV/AIDS including participation rates and employment outcome for program participants. A review of literature pertaining to employment interventions for individuals with HIV/AIDS is presented. Additionally, the systematic review methodology and results are presented. Finally, I discuss the results, limitations in regards to conducting the study, current research and recommendations for future research.
Employment of dual frequency excitation method to improve the accuracy of an optical current sensor, by measuring both current and temperature.
Optical current sensors (OCSs) are initially developed to measure relatively large current over a wide range of frequency band. They are also used as protective devices in the event a fault occurs due to a short circuit, in the power generation and distribution industries. The basic principal used in OCS is the Faraday effect. When a light guiding faraday medium is placed in a magnetic field which is produced by the current flowing in the conductor around the magnetic core, the plane of polarization of the linearly polarized light is rotated. The angle of rotation is proportional to the magnetic field strength, proportionality constant and the interaction length. The proportionality constant is the Verdet constant V (λ, T), which is dependent on both temperature and wavelength of the light. Opto electrical methods are used to measure the angle of rotation of the polarization plane. By measuring the angle the current flowing in the current carrying conductor can be calculated. But the accuracy of the OCS is lost of the angle of rotation of the polarization plane is dependent on the Verdet constant, apart from the magnetic field strength. As temperature increases the Verdet constant decreases, so the angle of rotation decreases. To compensate the effect of temperature on the OCS, a new method has been proposed. The current and temperature are measured with the help of a duel frequency method. To detect the line current in the conductor or coil, a small signal from the line current is fed to the reference of the lock in. To detect the temperature, the coil is excited with an electrical signal of a frequency different from the line frequency, and a small sample of this frequency signal is applied to the reference of the lock in. The temperature and current readings obtained are look up at the database value to give the actual output. Controlled environment is maintained to record the values in the database that maps the current and temperature magnitude values at the DSP lock in amplifier, to the actual temperature and current. By this method we can achieve better compensation to the temperature changes, with a large dynamic range and better sensitivity and accuracy.
The employment of historically-informed performance practices in present-day tuba performances of two Italian baroque violoncello transcriptions.
As several Italian baroque violoncello transcriptions have entered the standard performance repertory for both high school and collegiate tubists, and as numerous texts, articles, and baroque performance instruction courses have illuminated a new realm of performance possibilities, no published document has provided specific, thorough, and sample approaches to performance on the tuba of a given piece (or pieces) through a detailed application of materials found in any singular source or combination of sources. Many of the existing articles and texts that approach the subject focus largely on ornamentation, while limiting the discussion and application of the following topics: tempo, spirit, affect, notation, rhythm, dynamics, and articulation. This document examines such topics and provides detailed explanations and suggestions of historically-informed characteristics applicable to two movements each from the R. Winston Morris transcription of Antonio Vivaldi's Sonata No. 3 in A Minor and the Donald C. Little/Richard B. Nelson transcription of Benedetto Marcello's Sonata No. V in C Major.
Employment of Older Persons as Foster Grandparents
This thesis is a report of a study of the employment of foster grandparents for the foster grandparent project at the Denton State School in Denton, Texas. There were three specific interests in the study. First, it attempted to ascertain what criteria were used for the hiring of foster grandparents and how they were hired. Included in this area were the necessary steps which an individual had to take to apply for employment. Second, the study was concerned with developing a general description of the social and economic characteristics of those who were hired as foster grandparents, including their performance on certain tests which they took during the employment process. Third, it examined the relationship of selected social and economic characteristics to each other, the inter-relationships of test performance, and the relationships between the selected characteristics and test performance.
Employment of the Rorschach Inkblot Test with the Devries Suicide Inventory
This investigation represents an attempt to employ the Devries Suicide Prediction Scale and the Rorschach Inkblot Test in a two-stage predictive model which was designed to decrease the high false positive rate associated with the Devries and to design a way in which the Rorschach could be used efficiently in suicide prediction in a large mental hospital setting. The Rorschach was not found to significantly improve the predictive ability of the Devries. An unexpectedly high percentage of mental patients in the study, thirty-eight percent, admitted to previous suicide attempts, raising the question of whether suicidal behavior is not more common than is usually thought.

Empowering Agent for Oklahoma School Learning Communities: An Examination of the Oklahoma Library Improvement Program
The purposes of this study were to determine the initial impact of the Oklahoma Library Media Improvement Grants on Oklahoma school library media programs; assess whether the Oklahoma Library Media Improvement Grants continue to contribute to Oklahoma school learning communities; and examine possible relationships between school library media programs and student academic success. It also seeks to document the history of the Oklahoma Library Media Improvement Program 1978 - 1994 and increase awareness of its influence upon the Oklahoma school library media programs. Methods of data collection included: examining Oklahoma Library Media Improvement Program archival materials; sending a survey to 1703 school principals in Oklahoma; and interviewing Oklahoma Library Media Improvement Program participants. Data collection took place over a one year period. Data analyses were conducted in three primary phases: descriptive statistics and frequencies were disaggregated to examine mean scores as they related to money spent on school library media programs; opinions of school library media programs; and possible relationships between school library media programs and student academic achievement. Analysis of variance was used in the second phase of data analysis to determine if any variation between means was significant as related to Oklahoma Library Improvement Grants, time spent in the library media center by library media specialists, principal gender, opinions of library media programs, student achievement indicators, and the region of the state in which the respondent was located. The third phase of data analysis compared longitudinal data collected in the 2000 survey with past data. The primary results indicated students in Oklahoma from schools with a centralized library media center, served by a full-time library media specialist, and the school having received one or more Library Media Improvement Grants scored significantly higher academically than students in schools not having a centralized library media center, not served by a full-time library media specialist, and the school not having received one or more Library Media Improvement Grants. Students in schools having even one of these components scored higher academically than students in schools with none of these components.

Empowering the Black Community Faith-Based Economic Development
This paper is addressed to the inner city and some suburban congregations seeking to express their faith through practical initiatives to revitalize their distressed communities. The paper seeks to inspire and instruct the reader with motivational stories containing illustrations of the valuable role that African-American congregations have played in stimulating economic development in their communities. The paper also shows the importance of African-Americans having some control over the flow of economic funds throughout the community. African-American churches in the inner city should undertake significant ventures in community economic development to minister to the temporal as well as the spiritual needs of their communities. This paper will demonstrate how the African-American church, with assistance from federal, state, local programs, and private concerns, can be effective in the urban revitalization.
Empowerment: The Paradigm for Success for the Nursing Homes of the 21st Century
Access: Use of this item is restricted to the UNT Community.
For a workplace to be successful, it needs to have a higher morale, thus leading to higher quality of care for residents. For a workplace to be successful in empowerment, it must have developed strong teams, and everyone must work as a team and respect one another. The research for this paper focused on many issues. The most important part of my research came from a study of the nursing assistants at Jennings Hall (JH) in Garfield, Ohio. From the data received, I concluded that the two biggest problems in many nursing homes are lack of respect and lack of team-centered attitude.

The Empyrean: The Pinnacle of the Medieval World View (Twelfth-Fourteenth Centuries
The heavenly empyrean was the highest expression of the Medieval Weltanschauung (world view). It served as the outermost sphere of the Aristotelian/Ptolemaic geocentric cosmos while possessing an eminent theological status. This paper explores the importance of the empyrean during the Scholastic Period (eleventh through fourteenth centuries).
Emulation & Virtualization as Preservation Strategies
Between the two fundamental digital preservation strategies, migration has been strongly favored. Recent developments in emulation frameworks make it possible to deliver emulations to readers via the Web in ways that make them appear as normal components of Web pages. This removes what was the major barrier to deployment of emulation as a preservation strategy. Barriers remain, the two most important are that the tools for creating preserved system images are inadequate, and that the legal basis for delivering emulations is unclear, and where it is clear it is highly restrictive. Both of these raise the cost of building and providing access to a substantial, well curated collection of emulated digital artefacts beyond reach. This book advocates that if the above mentioned barriers can be addressed, emulation will play a much greater role in digital preservation in the coming years. It will provide access to artefacts that migration cannot, and even assist in migration where necessary by allowing the original software to perform it. The evolution of digital artefacts means that current artefacts are more difficult and expensive to collect and preserve than those from the past, and less suitable for migration. This trend is expected to continue. Emulation is not a panacea. Technical, scale and intellectual property difficulties make many current digital artefacts infeasible to emulate. Where feasible, even with better tools and a viable legal framework, emulation is more expensive than migration-based strategies. The most important reason for the failure of current strategies to collect and preserve the majority of their target material is economic; the resources available are inadequate. The bulk of the resources expended on both migration and emulation strategies are for ingest, especially metadata generation and quality assurance. There is a risk that diverting resources to emulation, with its higher per-artefact ingest cost, will exacerbate the lack of resources. Areas requiring further work if emulation is to achieve its potential as a preservation strategy include: • Standardization of the format of preserved system images, the way they are obtained by emulators, and the means by which emulations of them are exposed to readers. This would enable interoperability between emulation components, aiding contributions and support from the open-source community. • Improvements to the tools for associating technical metadata with preserved software to enable it to be emulated, and the technical metadata databases upon which they depend. This would reduce the cost of preserved system images. • Clarification, and if possible relaxation, of the legal constraints on the creation and provision of access to collections of preserved system images. This would encourage institutions to collect software.

Enacting Community Through the Arts
This study is concerned with the roles and relationships between artists-in-residence, community audiences, and program coordinators/art educators as they engage together in community arts programs. This study takes place at Project Row Houses (PRH), a community arts organization located in Houston, Texas and focuses on the artist-in-residence program, which commissions a group of national and international artists for a 6-month period to create art installations in relation to the community and its African-American heritage. This ethnographic case study is based on the activities and events surrounding the 2008 PRH exhibition, Round 29, Thunderbolt Special: The Great Electric Show and Dance, after Sam Lightnin’ Hopkins and employed qualitative data gathering methods of participant-observation, conducting semi-structured, open-ended, in-depth interviews, and through document collection, and contextual information. Observations were recorded through field notes, photographs, and video. Interviews were conducted with 3 artists-in-residence, 3 community audience members, and 3 program coordinators or staff members involved with the program, regarding their experiences at the site and experiences with each other. My analysis presents the roles of artist, community audience, and program coordinator/art educator through three sections on cultural work. Within these sections I discuss topics related to the power of voice, situatedness, and creativity, as it relates to the artists and community audiences. For the role of program coordinator/art educator, I focus more closely on her role in the process of mediation. Topics of power, social dynamics, identity, and representation are also framed within these discussions.
Enacting Racism: Clarence Thomas, George Bush, and the Construction of Social Reality
This study analyzes the confirmation hearings discourse of Clarence Thomas and George Bush. Language constructs social reality. The United States has a history of racism and this history manifests itself in our language. The discourse of Clarence Thomas and George Bush created a social reality that equated opposition to Thomas' confirmation with racism using rhetorical strategies that included metaphor and narrative construction.

The Enameling Arts in Kuwaiti Pre-service Art Teacher Education
Access: Use of this item is restricted to the UNT Community.
The purpose of this study was twofold: (1) to examine the knowledge, skills, and experiences in the enameling arts and the attitudes and perceptions of in-service (n = 12) and pre-service Kuwaiti art teachers (n = 170), art supervisors at the Ministry of Education (MOE) (n = 3) and art education faculty members at the College of Basic Education (CBE) and Kuwait University (KU) (n = 8) about what they believed pre-service art teachers should know and be able to do in order to teach the enameling arts, and (2) to use this information to inform and guide the development of a content outline for an enameling course for pre-service Kuwaiti art teachers that is educationally (how to perform enameling arts skills and how to teach what they know), practically (safety issues, workshop management, etc), and culturally (its relation to Islamic culture) suitable. Both quantitative and qualitative approaches were used. Most of the respondents revealed limited knowledge and skills and modest experiences in the enameling arts. All interviewees in the study expressed positive perceptions and attitudes about the enameling arts. Most agreed that a revision to the current art education curriculum at the CBE was needed and made suggestions about how the curriculum should be revised. It was clear that there is a disconnection and miscommunication between the MOE and the CBE with regards to the information about enameling that should be covered and taught in the art education classes. All respondents expressed support for the inclusion of a course in enameling in the art education curriculum at the CBE. Because of the limited knowledge of the participants in the study, they were not able to provide guidance in shaping the content for a course in the enameling arts. The researcher had to rely on the literature review and his expertise as an enameling artist to develop a content outline that was educationally, practically, and culturally suitable for the pre-service Kuwaiti art teachers. Further study was recommended in regard to curriculum issues, especially those related to the inclusion of Islamic culture, and methods of delivering instruction in the enameling arts.
Encoding Variability and Differential Negative Transfer and Retroactive Interference in Children
Second-graders were tested for negative transfer and retroactive interference using an A-B, A-D paradigm. Four-pair, word-number lists were aurally presented to the children. Subjects were classified as being whole-only encoders or multiple encoders by the use of a recall test presented after list one. Significant negative transfer and retroactive interference were found. The multiple encoders experiences less difficulty in learning the second list that did the whole-only encoders, but these two groups did no differ with regard to transfer or retroactive interference effects. The results were considered in the context of Martin's encoding variability hypothesis.

End of Insertion Detection in Colonoscopy Videos
Colorectal cancer is the second leading cause of cancer-related deaths behind lung cancer in the United States. Colonoscopy is the preferred screening method for detection of diseases like Colorectal Cancer. In the year 2006, American Society for Gastrointestinal Endoscopy (ASGE) and American College of Gastroenterology (ACG) issued guidelines for quality colonoscopy. The guidelines suggest that on average the withdrawal phase during a screening colonoscopy should last a minimum of 6 minutes. My aim is to classify the colonoscopy video into insertion and withdrawal phase. The problem is that currently existing shot detection techniques cannot be applied because colonoscopy is a single camera shot from start to end. An algorithm to detect phase boundary has already been developed by the MIGLAB team. Existing method has acceptable levels of accuracy but the main issue is dependency on MPEG (Moving Pictures Expert Group) 1/2. I implemented exhaustive search for motion estimation to reduce the execution time and improve the accuracy. I took advantages of the C/C++ programming languages with multithreading which helped us get even better performances in terms of execution time. I propose a method for improving the current method of colonoscopy video analysis and also an extension for the same to make it usable for real time videos. The real time version we implemented is capable of handling streams coming directly from the camera in the form of uncompressed bitmap frames. Existing implementation could not be applied to real time scenario because of its dependency on MPEG 1/2. Future direction of this research includes improved motion search and GPU parallel computing techniques.
End of Life Care: African Americans' Disproportionate Use of Hospice
The United States of America is a country composed of various ethnicities. This country is considered to be a multi-cultural society. There are various cultural traditions values, norms and superstitious practices within each ethnic group. Attitudes toward end of life care are complex and vary differently across each ethnic group. This study explored factors that explained African Americans' disproportionate use of hospice. Access to hospice care was address, experience with hospice was explored, and recommendations were provided. This study conducted non-experimental research. The design of this exploratory study was quantitative in nature. A survey approach was utilized to collect data that was statistically analyzed. The important concept was African American disproportionate use of hospice. The variable willingness to use was employed to try to explain African Americans' disproportionate use of hospice. The independent variables African Americans who mistrust formal healthcare providers and knowledge about hospice services were operationalized using multiple indicators. The independent variable experience with hospice services did not use a scale. The research findings supported all three study hypotheses. This research results recommend that an important focus of the future be to counsel persons on the availability of hospice as an option for end-of-life care. Well-structured programs of training in cultural awareness and cultural competence throughout the ranks of the health care system must be instituted. Such an effort will pay dividends in reducing cultural mistrust and push closer to eliminating health disparities between minority groups and the rest of society.

Endangered newspaper: An analysis of 10 years of corporate messages from the Dallas Morning News.
Most newspapers today are struggling to survive in an increasingly fragmented and digital media environment. How have their owners or corporate parents shaped or adapted their business practices to in order to thrive? This question guides the overall approach to this study. The focus is on one newspaper, the Dallas Morning News. In particular, how has the News used corporate messages to respond to the changing media landscape? This study employs forms of rhetorical and discourse analysis to determine the effectiveness of the News' corporate messages during a 10-year period in order to answer this question. This study finds that the News used inconsistent and ineffective corporate communications throughout this tumultuous period.
Endangered Species Act of 1973
The Endangered Species Act (ESA) provides a program for the conservation of threatened and endangered plants and animals and the habitats in which they are found. The U.S. Fish and Wildlife Service (FWS) of the Department of the Interior maintains a worldwide list which, as of Feb. 20, 2008, included 1574 endangered species (599 are plants) and 351 threatened species (148 are plants). Species include birds, insects, fish, reptiles, mammals, crustaceans, flowers, grasses, and trees. Anyone can petition FWS to include a species on this list. The law requires federal agencies, in consultation with the U.S. Fish and Wildlife Service and/or the U.S. National Oceanic and Atmospheric Administration Fisheries Service, to ensure that actions they authorize, fund, or carry out are not likely to jeopardize the continued existence of any listed species or result in the destruction or adverse modification of designated critical habitat of such species. The law also prohibits any action that causes a "taking" of any listed species of endangered fish or wildlife. Likewise, import, export, interstate, and foreign commerce of listed species are all generally prohibited.
Endocannabinoid System in a Planarian Model
In this study, the presence and possible function of endocannabinoid ligands in the planarian is investigated. The endocannabinoids ananadamide (AEA) and 2-arachidonoylglycerol (2-AG) and entourage NAE compounds palmitoylethanolamide (PEA), stearoylethanolamide (SEA) and oleoylethanolamide (OEA) were found in Dugesia dorotocephala. Changes in SEA, PEA, and AEA levels were observed over the initial twelve hours of active regeneration. Exogenously applied AEA, 2-AG and their catabolic inhibition effected biphasic changes in locomotor velocity, analogous to those observed in murines. The genome of a close relative, Schmidtea mediterranea, courtesy of the University of Utah S. med genome database, was explored for cannabinoid receptors, none were found. A putative fatty acid amide hydrolase (FAAH) homolog was found in Schmidtea mediterranea.
Endocrine Disruption of Levonorgestrel in Early-life Stages of Fathead Minnows, Pimephales Promelas
Pharmaceuticals have routinely been detected in the environment resulting in a growing concern about whether these drugs could elicit effects on aquatic organisms. The concerns are centered on the highly conserved nature of mammalian therapeutic targets in fish. These pharmaceuticals are found at very low levels in the environment, which can result in sub-lethal effects in aquatic organisms. Therefore, 28 d early-life stage studies were conducted on six pharmaceuticals to assess their impacts on survival and growth fathead minnow larvae. Two pharmaceuticals tested, carbamazepine and fenofibrate, resulted in no alterations to survival and growth. However, amiodarone, clozapine, dexamethasone, and levonorgestrel (LNG) reduced survival at concentrations tested with LNG being the most potent at 462 ng/L. Survival was increased with amiodarone and clozapine; however LNG significantly decreased growth at 86 ng/L. Therefore, the most potent pharmaceutical tested was the synthetic progestin LNG with survival and growth impacts at concentrations less than 1 μg/L. Further analysis was conducted by measuring specific endocrine related mRNA transcript profiles in FHM larvae following the 28 d ELS exposure to LNG. Transcripts of 3β-HSD, 20β-HSD, and FSH were significantly down-regulated following 28 d exposure to both 16.3 and 86.9 ng/L LNG. Also, CYP19a expression was significantly down-regulated at 86.9 and 2392 ng/L LNG. Subsequently, a second study examined time periods that may be most sensitive (e.g., windows of sensitivity) for FHM larvae exposed to LNG. Larvae were exposed to a single concentration of LNG (i.e. LOECgrowth of 86.2 ng/L as determined in the 28 d ELS study) for different time periods starting with fertilized egg through 28 dph. Growth and mRNA expression of the four differentially expressed transcripts from the first study were measured. Regardless of the duration of exposure, LNG significantly decreased growth in fathead minnow larvae at day 28. For both 20β-HSD and CYP19a, mRNA expression was decreased following exposure to LNG; however, these transcripts returned to baseline levels after removal of LNG. 3β-HSD and FSH showed similar trends after exposure to LNG with 7-14 d and 14-28 d exposures exhibiting a decrease in expression; however, FSH expression returned to baseline once removed for LNG exposure. Based on these data, 3β-HSD was the only transcript to remain down regulated after LNG exposure. Together these data suggest LNG can negatively impact FHM larval survival and growth, with significant alterations in endocrine related responses. However, these changes in endocrine related responses may not directly correlate to the changes in growth demonstrated with LNG exposure to fathead minnows. Therefore, additional research is warranted to ascertain additional mechanisms, either endocrine related or non-endocrine functions, related to changes in growth of larval fathead minnows.
Endogenous Constructivist Implications for Methodology : Focus on Young Children with Developmental Delay in the Social and Emotional Domains
The Ecologically-Based Activity Plan (EBAP) is proposed as a method to create a transition between special education and general education. It serves as a tool to help classroom teachers assess the environment of the class and as a method for embedding instruction within the naturally occurring context of the endogenous constructivist classroom. In this study the EBAP was used to reduce aggressive behavior and increase prosocial behavior among five children who displayed developmental delays in the social and emotional domains.
Endogenous Information and Inter-state War Expansion
Scholars have long debated the causes of late third party state joining in ongoing inter-state wars. This research has generally concluding that peace-time conditions, measured in terms of: third party capabilities; proximity to warring states; and inter-state alliances, are determining factors in the decision to join. However, these studies utilize theories derived from static pre-war measures of capabilities and motivation to explain late joining; indeed, the same measures that fail to predict participation at war's outset. Further, extant research has no explanation for why weak and non-proximate states every participate. Existing theory thus fails to provide a comprehensive explanation of joining behavior. This project contends that a resolution lies the interaction between pre-war conditions and intra-war events. Intra-war events that are allowed to vary on a per battle basis, including change in combat location and alliance entry and exit from combat, reveal new information about the war and its progress, thereby forcing third party states to recalculate their initial decision to abstain in relation to their pre-existing situation. Incorporation of intra-war processes helps to better explain decisions by third party states to join ongoing inter-state wars late in their development, and why states that frequently choose to abstain (e.g., weak states) ever choose to participate. This project is executed using a combination of ex post facto historical case studies, a theory of joining based on pre and intra-war environments, and large-N empirical analysis on all inter-state wars 1823-1988, conducted utilizing a novel collection of event-level data based on inter-state war battles.
