This study investigated the effects of a shaping program for halter training across 8 steps in the program and 4 trial-terminating, or "undesirable," responses. Three La Mancha goats (Capra hircus) located at the Frank Buck Zoo in Gainesville, Texas were used for the study. A fixed-time 15 s (FT-15 s) was used during the baseline conditions, to examine the effects of response contingent and response-independent food deliveries, as well as to examine what preliminary steps might not necessarily have to be shaped. All 3 goats successfully learned to allow the halter to be placed on them and to lead on the halter, although 2 of the 3 goats required an additional task analysis for the fifth step to further break down that approximation. Several of the early steps selected by the researchers were not necessary to complete the program, as determined by the baseline condition.
This study sought to determine if and how television texts produced since September 11, 2001, reflect and address cultural concerns by analyzing patterns in their theme and narrative style. Three American television serials were examined as case studies. Each text addressed a common cluster of contemporary issues such as trauma, death, and loss.
Objective: Differences between biologic and non-biologic parents' acceptance and use of ordinary corporal punishment and use of explaining/reasoning as a disciplinary tool are examined from a sociobiological theoretical perspective. Method: Cross tabulations are used on data from a national survey conducted by the Gallup Organization in 1995. Results: Contrary to predictions, differences between biologic and non-biologic parents' acceptance of ordinary corporal punishment and the use of explaining/reasoning are not statistically significant. In addition, biologic parents are found to use ordinary corporal punishment significantly more often than non-biologic parents. Conclusions: The sociobiological theoretical perspective likely underestimates the influence of culture and social structure on parent-child interactions.
In 1939, composer Julia Smith's first opera Cynthia Parker dramatized the story of a Texas legend. Smith manipulated music, text, and visual images to make the opera accessible for the audience in accordance with compositional and institutional practices in American opera of the 1930s. Transparent musical themes and common Native Americans stereotypes are used to define characters. Folk music is presented as diegetic, creating a sense of authenticity that places the audience into the opera's Western setting. The opera is codified for the audience using popular idioms, resulting in initial but not lasting success.
This thesis examines the representation of Mormon men in American film and television, with particular regard for sexual identity and the cultural association of Mormonism with sexuality. The history of Mormonism's unique marital practices and doctrinal approaches to gender and sexuality have developed three common stereotypes for Mormon male characters: the purposeful heterosexual, the monstrous polygamist, and the self-destructive homosexual. Depending upon the sexual stereotype in the narrative, the Mormon Church can function as a proponent for nineteenth-century views of sexuality, a symbol for society's repressed sexuality, or a metaphor for the oppressive effects of performing gender and sexuality according to ideological constraints. These ideas are presented in Mormon films such as Saturday's Warrior (1989) as well as mainstream films such as A Mormon Maid (1917) and Advise and Consent (1962).
The present study examines the relationship between acculturation, parental control, and psychological adjustment among adult first and second-generation Asian Indian women who have immigrated, or whose parents have immigrated to the United States, from the Indian state of Kerala. Data from 73 participants indicate second-generation immigrants report poorer psychological adjustment than do their counterparts. Additionally, regression analyses reveal discomfort towards Kerala culture significantly predicts depressive symptoms, while high maternal control predicts self-esteem. Qualitative data were collected to provide richer understanding of immigrants' adaptation to the U.S. Implications of this research may impact mental health practitioners' ability to improve quality of life with Asian Indian women from Kerala.
The determination of adiposity in adolescents is often assessed with calculations of body mass indices (BMI). Researchers often obtain these measurements from self-reported (SR) values. The purpose of this study was to determine the accuracy of SR height, weight, and calculated BMI (from height and weight). SR and actual measured (ME) BMI values were compared with standards from the FITNESSGRAM® Healthy Fitness Zone (HFZ) classifications. SR height and calculated BMI were found to be accurate while SR weight was, on average, underreported by 4.77 lbs. Because of these errors in SR height and weight, accuracy of classification into the FITNESSGRAM® HFZ was compromised. Consequently, it is important that researchers ascertain actual values of height and weight when measuring adolescents rather than use those from self-reports.
This study examined the relationship between time of exposure to the human face and accurate subsequent photo line-up identification. A volunteer group of 124 undergraduate students was divided into three approximately equal sized subgroups. The three groups were then exposed to a video or a portion of a video depicting a theft. Exposure times ranged from two minutes to 30 seconds. The subjects were then given a questionnaire and shown a photo line-up of the mock perpetrator and five foils. Subjects were asked to identify the perpetrator and mark that identification on the questionnaire. Results of the experiment indicated that the longer a subject was exposed the greater the possibility of an accurate identification.
One of the most important factors for creating the sustainable society is that the individuals in that society behave in an environmentally sustainable fashion. Yet achieving appropriate behavior in any society is difficult, and the challenge is no less with regards to sustainability. Three of the most important factors for determining behavior have recently been highlighted by psychologists: personal efficacy, social influence, and internal standards. Because these three factors play a prominent role in behavior, it is necessary to examine what role they play in creating sustainability and how they may be utilized to achieve optimal behavior patterns. Ultimately, in order to achieve sustainability solutions must focus on individual action, realistic governmental regulation, and sustained, direct encounters with the natural world. While much time and energy has been spent on social influence and personal efficacy, less has been devoted to internal standards and this area needs more attention if there is to be any realistic attempt at creating proper behavior patterns.
Airpower played an important supporting role in the Korean War, and as General of the Army Douglas MacArthur pursued victory in the war and President Harry S Truman's objectives altered throughout the first year of the conflict, tension arose between the two men. One issue in these frictions was the restriction of airpower. Not only MacArthur, but also his admiring subordinate Lieutenant General George E. Stratemeyer commanding the Far East Air Forces, and Fifth Air Force commander Major General Earle E. Partridge opposed the restrictions which had been imposed on airmen from the outset of the conflict. Stratemeyer did so partly because of his loyalty to MacArthur, who wanted latitude in coping with the situation in the field and defeating the Communist enemy. Partridge did so because he thought they endangered his personnel and limited the effectiveness of airpower in the war. These commanders had a fundamentally different opinion from Washington regarding the likelihood of overt Soviet intervention in the war, and because they did not think the Korean War would become a world war, they were more willing than Washington to prosecute the war more aggressively. MacArthur's conflict ended with his removal in April 1951, and Stratemeyer (who suffered a heart attack weeks afterward) continued to advocate for forceful American foreign policy in Asia during his retirement. Partridge eventually earned four stars and long after the war likewise continued to disfavor the restrictions which had been put in place. Between oral history interviews in 1974 and 1978, however, Partridge reconsidered the issue of restrictions. He expressed that the Korean War had been a considerable challenge without a wider war, implying that restrictions had perhaps been important.
An understanding of the potential roles as lipid mediators of a family of bioactive metabolites called N-acylethanolamines (NAEs) depends on their accurate identification and quantification. The levels of 18C unsaturated NAEs (e.g. NAE18:2, NAE 18:3, etc.) in wild-type seeds (about 2000 ng/g fw) generally decreased by about 80% during germination and post-germinative growth. In addition, results suggest NAE-degradative fatty acid amide hydrolase (FAAH) expression does not play a major role in normal NAE metabolism as previously thought. Seedlings germinated and grown in the presence of abscisic acid (ABA), an endogenous plant hormone, exhibited growth arrest and secondary dormancy, similar to the treatment of seedlings with exogenous NÂlauroylethanolamine (NAE12:0). ABA-mediated growth arrest was associated with higher levels of unsaturated NAEs. Overall, these results are consistent with the concept that NAE metabolism is activated during seed germination and suggest that the reduction in unsaturated NAE levels is under strict temporal control and may be a requirement for normal seed germination and post-germinative growth.
The purpose of this study was to determine the degree to which existing aquatic facilities in the North Texas metroplex complied with the 1991 Americans with Disabilities Act Accessibility Guidelines (ADAAG) and the proposed Americans with Disabilities Act Accessibility Guidelines: Recreation Facilities (ADAAG supplement). Fifty-two aquatic facilities were evaluated based on: parking lot, ticket counter, gate/entry, restroom, dressing area, drinking fountain, pathway, and pool entry method structural domains. Physical measurements and a few direct observations were recorded on the survey instrument. Surveys were then reviewed and facility scores were tabulated. No facility was found to be 100% compliant with ADAAG and the ADAAG supplement. Aquatic facilities are already struggling to catch up with the 1991 ADAAG, but when the United States Department of Justice approves the proposed ADAAG supplement, aquatic facilities will fall even further behind.
Charles I, King of Spain, or Charles V, Holy Roman Emperor, was the most powerful ruler in Europe since Charlemagne. With a Germanic background, and speaking French, Charles became King of Spain in 1516. Yet secondary sources and available sixteenth century Spanish sources such as Spanish Royal Council records, local records of Castro Urdiales in Castile, and Charles's correspondence show that he continued the policies of his predecessors in Spain, Ferdinand of Aragon and Isabella of Castile. He strove to strengthen his power and unify Spain and his empire using Castilian strength, a Castilian model of government, Roman law, religion, his strong personality, and a loyal and talented bureaucracy. Charles desired to be another Charlemagne, but with his base of power in Spain.
Twenty-five adolescents' ranking of a set of equally highly valued goals on a Paired-comparisons Survey was compared with what adolescents say they are doing to achieve those goals. Results of the Paired-comparisons Survey showed that adolescents ranked career, interpersonal, and educational goals rather high and reputation and self-presentation goals rather low. Results analyzed with a contingency coefficient and biserial correlation indicated that not all number one ranked goals had the same value for a particular adolescent, and that number one ranked goals were correlated with verbal reports of concrete actions directed at achieving those goals.
Recent research found insomnia is a risk factor for psychiatric disorders in adults. To see if the same would be true in adolescents, the current study re-analyzed data from a national longitudinal study collected by ADDHealth that evaluated health behaviors in 4552 adolescents (mean age 14.9 years [SD 1.7]) at baseline and again 7-8 years later (n = 3489) during young adulthood. Insomnia was reported by 9.2% of the adolescents. Cross-sectionally, adolescent insomnia was associated with alcohol, cannabis, non-cannabis drugs, and tobacco use, and depression after controlling for gender and ethnicity. Prospectively, adolescent insomnia was a significant risk factor for depression diagnosis, suicidal ideation, and the use of depression and stress prescription medications in young adulthood after controlling for gender, ethnicity, and significant baseline variable. In addition, a trend was noted for suicidal attempts.
Psychopathy, as conceptualized by Cleckley (1941), describes a constellation of psychological and behavioral correlates including superficial charm, untruthfulness, lack of remorse or shame, poor judgment, and failure to learn from experience. Based on Cleckley's initial work, Hare (1991) developed a two-factor model of psychopathy. The purpose of this study was to investigate the roles that sensation seeking, impulsivity, ADHD, conduct disorder, and oppositional defiant disorder have on adolescents classified as psychopaths. The participants consisted of 79 adjudicated male adolescents in a maximum-security facility. As hypothesized, adolescent male psychopaths had higher levels of sensation seeking, impulsivity, conduct disorder and oppositional defiant disorder. A discriminant function analysis found that sensation seeking, impulsivity, ADHD, Conduct Disorder, and Oppositional Defiant Disorder was moderately useful in classifying adolescent psychopathy. The results suggest that behavioral dysregulation is an important aspect of adolescent psychopathy. The relationship of these data to theories of adolescent psychopathy is discussed.
Philip Glass' Glassworks (1981) is a six-movement composition for two flutes, two soprano saxophones/clarinets, two tenor saxophones/bass clarinets, two French horns, violas, cellos, and the DX7 electric piano. Glassworks consists of six movements titled "Opening," "Floe," "Island," "Rubric," "Facades," and "Closing." This thesis covers the first movement "Opening." Repetition in musical minimalism confronts traditional prescriptive codes of tonal music and post-tonal music. While challenging the traditional codes, repetition in musical minimalism established new codes for listening to minimal music. This thesis explores the implications of these ideas.
Job satisfaction is one of the most commonly studied variables in the organizational literature. It is related to a multitude of employee-relevant variables including but not limited to performance, organizational commitment, and intent to quit. This study examined two new instruments measuring the components of affect and cognition as they relate to job satisfaction. It further proposed including an evaluative (or true attitudinal) component to improve the prediction of job satisfaction. Results provide some evidence of both two and three factor structures of affect and cognition. This study found minimal support for the inclusion of evaluation in the measurement of job satisfaction. Affect was found to be the single best predictor of job satisfaction, regardless of the satisfaction measure used. Further development is needed to define the factor structures of affect and cognition as well as the role of these factors and evaluation in the prediction of job satisfaction.
Peer-to-Peer (P2P) networks have seen tremendous growth in development and usage in recent times. This attention has brought many developments as well as new challenges to these networks. We will show that agent extensions to P2P networks offer solutions to many problems faced by P2P networks. In this research, an attempt is made to bring together JXTA P2P infrastructure and Jinni, a Prolog based agent engine to form an agent based P2P network. On top of the JXTA, we define simple Java API providing P2P services for agent programming constructs. Jinni is deployed on this JXTA network using an automated code update mechanism. Experiments are conducted on this Jinni/JXTA platform to implement a simple agent communication and data exchange protocol.
The plurality of worlds has had a long history in England, which has not gone unnoticed by scholars. Historians have tended to view this English pluralist tradition as similar to those found on the continent, and in doing so have failed to fully understand the religious significance that the plurality of worlds had on English thought and society. This religious significance is discovered through a thorough investigation of plurality as presented by English natural philosophers and theologians, and in so doing reveals much about England in the seventeenth century. As natural philosophers incorporated plurality within the larger framework of natural theology, it became a weapon of science and reason to be used against the unreasonable atheists of late seventeenth-century England.
This study examines two of the smaller American choral societies that together existed for just over 30 years, 1888 to 1919: The Gounod and New Haven Oratorio Societies of New Haven, Connecticut. These societies are important because, especially in the case of the New Haven Society, they were closely related to Yale University and the work of Horatio Parker. One must assume from the onset that the two choral groups examined in the following pages did not have the prominence of the many larger New England choral societies. However a more detailed knowledge about the struggles, successes, influence and leadership of two smaller societies illuminates a field of research in the history of American choral music that has been largely ignored.
In this thesis, I address the dichotomy between liberal arts education and terminal vocational training in the American community college. The need is for reform in the community college in relation to philosophical instruction in order to empower citizens, support justice and create more sustainable communities. My call for reform involves a multicultural integration of philosophy into terminal/vocational programs as well as evolving the traditional liberal arts course to exist in a multicultural setting. Special attention is focused on liberating the oppressed, social and economic justice and philosophy of education.
From 1930 to 1955, Amon Carter, publisher of the Fort Worth Star-Telegram, exerted his power to create modern Fort Worth. Carter used his stature as the publisher of the city's major newspaper to build a modern city out of this livestock center. Between 1930 and 1955, Carter lobbied successfully for New Deal funds for Fort Worth, persuaded Consolidated Aircraft to build an airplane plant in the city, and convinced Burlington Railways to stay in the city. He also labored unsuccessfully to have the Trinity River Canal built and to secure a General Motors plant for Fort Worth. These efforts demonstrate that Carter was indeed the founder of modern Fort Worth.
While amorphous phases have been reported in immiscible alloy systems, there is still some controversy regarding the reason for the stabilization of these unusual amorphous phases. Direct evidence of nanoscale phase separation within the amorphous phase forming in immiscible Cu-Nb alloy thin films using 3D atom probe tomography has been presented. This evidence clearly indicates that the nanoscale phase separation is responsible for the stabilization of the amorphous phase in such immiscible systems since it substantially reduces the free energy of the undercooled liquid (or amorphous) phase, below that of the competing supersaturated crystalline phases. The devitrification of the immiscible Cu-Nb thin film of composition Cu-45% Nb has been studied in detail with the discussion on the mechanism of phase transformation. The initial phase separation in the amorphous condition seems to play a vital role in the crystallization of the thin film. Detailed analysis has been done using X-ray diffraction, transmission electron microscopy and 3D atom probe tomography.
This thesis examines existing curricula at colleges and universities about sustainability and uses results to develop an introductory post secondary course curriculum. The proposed course is organized around three major elements - - science, philosophy, and economics - - all integral to understanding sustainability. Materials needed to teach the proposed 3-semester hour course including syllabus, teaching modules, transparencies, handouts, and exams were developed. Suggestions on how to teach a one-semester hour course on sustainability and a workshop on sustainability are also presented. The following research and curriculum development was a project established and funded by the Texas Energy Office, Renewable Resources and Sustainability Program.
This research paper addressed the following question: Do select case studies conform to Dr. Freda Adler's theory regarding socio-economic influences on female criminal behavior or dispute her theory? My research involved three female criminals: Karla Faye Tucker, Andrea Yates, and Susan Smith. I addressed Adler's theory in detail, other theories, the makeup of the female criminal and various female crimes. This study provided evidence that all three case studies conform to Adler's theory. nIn accordance with Adler's theory, each of these three females committed crimes of accessibility. None of the three individuals sought to commit a premeditated act or to murder unknown victims. They were motivated by emotions arising at a point in time when access/opportunity presented itself.
In this project I explore the connection between cultural and personal identity in the college classroom. Respondent interviews were conducted using open-ended questions, which began with a broad picture of the role the instructor played in the classroom and then focused more specifically on the issue of sexual orientation and the choices to disclose or not disclose orientation in the classroom. Thematic analysis was used to examine the interviews, upon the completion of the interviews being transcribed. RQ1: Do gay and lesbian instructors disclose their sexual orientation in the classroom? From this question, four themes emerged. These themes were disclosure not relevant, out of the classroom disclosure, students just know, and disclosure in the classroom. RQ2: What reasons do gay and lesbian instructors give for disclosing their sexual orientation in the classroom? Two themes, fears of disclosure and holding back, transpired from this question. RQ3: How do gay and lesbian instructors foster diversity in the classroom related to sexual orientation? Four themes were exposed from the question, and these themes were paradox of diversity, passing, mentoring, and identity not sexuality.
Motor vehicle theft is the costliest property crime in the United States equaling billions of dollars in losses each year. Despite law enforcement success in decreasing the rate of motor vehicle theft in recent years, the actual number of thefts has increased. It is vital for law enforcement agencies to know who is committing motor vehicle theft and where vehicles are being stolen. This study answers these questions by examining offender demographic characteristics and the location types most targeted for motor vehicle theft in Texas from 2001 to 2005. The state of Texas was chosen because Texas has continually been ranked second in the Federal Bureau of Investigation's Uniform Crime Report for the number of reported incidents of motor vehicle theft in the United States.
By conducting sound research to understand the concepts surrounding rioting and efficient riot response tactics, professionals, especially whose main job is to ensure the tranquility in the society, will be better prepared to deal with all kinds of civil movements. The purpose of this study, consequently, is to meet the growing need for educational materials in this area and to provide riot response case studies, which demonstrate the numerous administrative challenges faced by law enforcement decision makers. In this study, seven major riots from throughout the United States are discussed including the Hay Market Riot of 1886, the Watts Riot of 1965, and Los Angeles Riots of 1992. Each riot case is studied in five different and independent stages: the setting and pre-disturbance situation, basic causes of the event, the disturbance situation, the response to the riot, and the aftermath of the incident. The study of all of these stages is intended to help police administrators acquire a general perspective on collective violence, and help them prevent future occurrences in their jurisdictions. In this thesis a special reference is given to the deficiencies of American riot policing and some recommendations were formed accordingly. Therefore, the study concludes with a list of general recommendations, which are crucially important for concerned officials to pay attention before, during, and after a riot.
Guiding navigation in virtual environments (VEs) is a challenging task. A key issue in the navigation of a virtual environment is to be able to strike a balance between the user's need to explore the environment freely and the designer's need to ensure that the user experiences all the important events in the VE. This thesis reports on a study aimed at comparing the effectiveness of various navigation cues that are used to motivate users towards a specific target location. The results of this study indicate some significant differences in how users responded to the various cues.
Although several guidelines are available for designing observational procedures in both basic and applied settings, few researchers have experimentally examined and compared different direct observation methods. Such methods may have a direct impact on practitioners' ability to effectively assess strengths and challenges, set treatment goals, adjust intervention procedures, and monitor progress. The current study compared 1 and 5 min observations to 10 min observations throughout baseline and intervention phases of a parent training program for toddlers with autism. Results showed similarities with regards to variability, level, and trend in the 5 and 10 min data samples; however, clear differences were seen in the 1 min data sample, which typically showed very low occurrences of responding and displayed steady and flat trends. The findings have implications for the development of time-efficient direct observation procedures utilized in parent training programs for children with autism.
Terrorism has been claimed to be a major problem by hundreds of thousands of people in the international arena for years. Either it has been very difficult to determine and understand the reasons for terrorism, or those reasons have never been studied because of the immediate threat of terrorism. This research analyzed the recruitment process of terrorists by studying the DHKP/C terrorist organization and by answering the following questions. The first is "What factors are correlated with joining a terrorist organization?" And the second is "What is the recruitment process of the DHKP/C?" IN the course of this research, I used specific reports written by DHKP/C members and personal experience to come to better understanding of the motivation behind terrorism and the process by which people are recruited in the terrorist organizations.
This is a study of Bartók's compositional process as it relates to the Improvisations, Op. 20. The study, which focuses on the analysis of the draft manuscript 50PS1, compares the draft and other relevant sources with the final composition. Bartók's framework for the entire Improvisations is based on a compositional strategy of pairing individual improvisations combined with systematic revision of the draft copy by the introduction of tritones as tonal equivalents and movement by fifths from semitones, to achieve structural coherence in the individual improvisations. The tonic-dominant relationship is used to rearrange the individual improvisations in the draft and tritones as tonal equivalents are used to propel the movement between the improvisations to produce a coherent whole.
The science-major General Chemistry sequence offered at the University of Houston has been investigated with respect to the effectiveness of recent incorporation of various levels of computer technology. As part of this investigation, questionnaire responses, student evaluations and grade averages and distributions from up to the last ten years have been analyzed and compared. Increased use of web-based material is both popular and effective, particularly with respect to providing extra information and supplemental questions. Instructor contact via e-mail is also well-received. Both uses of technology should be encouraged. In contrast, electronic classroom presentation is less popular. While initial use may lead to improved grades and retention, these levels decrease quickly, possibly due to a reduction in instructor spontaneity.
This study analyzes the remaining suitable habitat of the one-horned rhinoceros, Rhinoceros unicornis, in Royal Chitwan National Park of Nepal. An April 2003 Landsat image was classified into eight land cover types: wetland, sand, water, mixed forest, sal forest, agriculture, settlement, and grassland. This image was converted into habitat suitability maps using cover, food, and water. The rhinoceros prefers grassland habitat with oxbow lakes and closed canopy during the monsoon season. Nominal values of five parameters were used to create a map of habitat suitability index. The map was categorized into four habitat classes: highly unsuitable, unsuitable, moderately suitable habitat, and suitable. Landscape metrics, patch metrics and class metrics associated with habitat were determined through the use of FRAGSTATS.
This study examined the opinions of university students about the current situation of the headscarf dispute on the wearing of headscarves in Turkey. The influence of gender, the level of secularism, socioeconomic status and encounter with women wearing headscarves on opinions about the wearing of headscarves were analyzed in this study. The sample of this study was composed of 400 university students among whom there were 240 female and 160 male students. Moreover, the sample comprised university students from 50 universities from Turkey. The results indicated that the level of secularism and encounter with women wearing headscarves were distinguished as two determining factors of the diverse opinions of the university students on the topic. No association was found between the perceptions of university students about the issue and the independent variables of gender and socioeconomic status.
This pilot study addresses the distribution of nonstandard syntactic and lexical features in Indian English (IE) across a homogeneous group of highly educated IE speakers. It is found that nonstandard syntactic features of article use, number agreement and assignment of verb argument structure do not display uniform intragroup distribution. Instead, a relationship is found between nonstandard syntactic features and the sociolinguistic variables of lower levels of exposure to and use of English found within the group. While nonstandard syntactic features show unequal distribution, nonstandard lexical features of semantic reassignment, and mass nouns treated as count nouns display a more uniform intragroup distribution.
The Internet became a standard way of exchanging business data between B2B and B2C applications and with this came the need for providing various services on the web instead of just static text and images. Web services are a new type of services offered via the web that aid in the creation of globally distributed applications. Web services are enhanced e-business applications that are easier to advertise and easier to discover on the Internet because of their flexibility and uniformity. In a real life scenario it is highly difficult to decide which J2EE application server to go for when deploying a enterprise web service. This thesis analyzes the various ways by which web services can be developed & deployed. Underlying protocols and crucial issues like EAI (enterprise application integration), asynchronous messaging, Registry tModel architecture etc have been considered in this research. This paper presents a report by analyzing what various J2EE application servers provide by doing a case study and by developing applications to test functionality.
The sample used for evaporative cooling system is Fabric defender 750 with Shelltite finish. From the experimental data and equations we have diffusion coefficient of 20.9 ± 3.71 x 10-6 m2/s for fabric with one layer with 17%-20% fluctuations from the theory, 27.8 ± 4.5 x 10-6 m2/s for fabric with two layers with 6%-14% fluctuations from the theory and 24.9 ± 4.1 x 10-6 m2/s for fabric with three layers with 13%-16% fluctuations from the theory. Since the thickness of the fabric increases so the mass transport rate decreases so the mass transport resistance should be increases. The intrinsic mass resistances of Fabri-1L, Fabri-2L and Fabri-3L are respectively 104 ± 10.2 s/m, 154 ± 23 s/m and 206 ± 26 s/m from the experiment.
Modern communication systems rely heavily upon microwave, radio, and other electromagnetic frequency bands as a means of providing wireless communication links. Although convenient, wireless communication is susceptible to electromagnetic interference. Solar activity causes both direct interference through electromagnetic radiation as well as indirect interference caused by charged particles interacting with Earth's magnetic field. The Solar Radio Burst Locator (SRBL) is a United States Air Force radio telescope designed to detect and locate solar microwave bursts as they occur on the Sun. By analyzing these events, the Air Force hopes to gain a better understanding of the root causes of solar interference and improve interference forecasts. This thesis presents methods of searching and analyzing events found in the previously unstudied SRBL data archive. A new web-based application aids in the searching and visualization of the data. Comparative analysis is performed amongst data collected by SRBL and several other instruments. This thesis also analyzes events across the time, intensity, and frequency domains. These analysis methods can be used to aid in the detection and understanding of solar events so as to provide improved forecasts of solar-induced electromagnetic interference.
This study examined the effect of a score card¬-based performance pay plan in a professional services firm. The plan was implemented in response to a decreasing trend in productivity and a desire for a formal incentive compensation plan. Performance of manager and senior manager accountants were analyzed across two departments over a five year period. A definitive account of the effects of the intervention is limited by the case-¬study design, but the data does suggest that the performance pay plans used did not adversely affect performances. Design limitations of the plan and future research are also discussed.
This syllabus includes both lecture notes and laboratory activities for a two-semester anatomy and physiology community college course. The syllabus is based on a 16-week semester that is comprised of a three-hour lecture section and a one-hour laboratory class each week. Both the lecture course and laboratory are necessary to fulfill the requirement for anatomy and physiology. Laboratory activities coincide with lectures to enhance understanding of each topic by providing visual and hands-on experiments for the concepts learned in the lecture. Laboratory quizzes will be given each week to help students maintain a working knowledge of the material learned in the laboratory. This course is appropriate for the typical anatomy and physiology student and should benefit both students who plan to major in biology and also those who are non-biology majors. Because subject matter in anatomy and physiology is quite difficult, the importance of attendance and good study skills is stressed.
This paper discuses the British Labour government's social, economic and military policies in Iraq between 1945 and 1948. The ability of the Iraqi monarchy to adapt to the British policies after World War II is discussed. The British were trying to put more social justice into the Iraqi regime in order to keep British influence and to increase the Iraqi regime's stability against the Arab nationalist movement.
The thesis has two parts. Part I is a critical essay entitled "Lessons Under the Amfalula." Part II is the collection of poems entitled "Animals That Die."
The purpose of this thesis is to present a comprehensive colligation of applications of mobile agents in networks, and provide a baseline association of these systems. This work has been motivated by the fact that mobile agent systems have been deemed proficuous alternatives in system applications. Several mobile agent systems have been developed to provide scalable and cogent solutions in network-centric applications. This thesis examines some existing mobile agent systems in core networking areas, in particular, those of network and resource management, routing, and the provision of fault tolerance and security. The inherent features of these systems are discussed with respect to their specific functionalities. The applicability and efficacy of mobile agents are further considered in the specific areas mentioned above. Although an initial foray into a collation of this nature, the goal of this annotated bibliography is to provide a generic referential view of mobile agent systems in network applications.
An extensive study of disubstituted cycloalkanes like CnH2n where n=3,4,5 and 6 using DFT((U)B3LYP/6-31G(d) and 6-311+G(2df,2p)) calculations is presented focusing on the effect of pyramidalization of the radical center. A potential energy surface (PES) analysis shows that the radical prefers to pyramidalize anti to the two cis fluorines in the disubstituted cycloalkanes. The degree of pyramidalization for 1,2-difluorocyclopropyl radical is 43.9o away from the cis fluorines whereas for 1,3-difluorocyclobutyl radical, 1,3-difluorocyclopentyl radical and 1,3-difluorocyclohexyl radical is 3.8o, 5.4o and 14.5o respectively away from the cis fluorines. The importance of this pyramidality effect in these compounds is discussed in context with the carbon-hydrogen bond dissociation energies (BDE's) because the preference of the radical centers to pyramidalize anti to the fluorines affects the bond dissociation energy. Importance of steric effect and unfavorable electronic interactions have been extensively explored in planar permethylated cyclobutadiene (Me4CBD) and cyclooctatetraene (Me8COT) using ((U)B3LYP/6-31G(d) and 6-311+G(2df,2p)) calculations. It is thought that steric interactions dominate electronic interactions in Me8COT, while this works opposite in case of Me4CBT. Instead, in Me4CBD the number of unfavorable electronic interactions between π bonds and out-of-plane hydrogens plays the dominant role in determining the relative energies. Interactions between the π bonds of CBD and the out-of-plane hydrogens on carbons attached to the four-membered ring becomes very interesting when the ring size changes. With ethano bridge on the cyclobutadiene ring interaction with the diagonal bonds results in non-bonding AOs across the other diagonal having the opposite phase in the highest occupied (HO)MO. If the HOMO and LUMO are switched, bis-ethano-bridged tetrahedrane is formed. It is suggested that bis-ethano-bridged tetrahedrane is thermodynamically more stable than bis-ethano-bridged cyclobutadienes. While the reverse is true for unsubstituted cyclobutadienes. The ability of ethano bridges to reverse the usual order is because it causes the doubly-bonded carbons to pyramidalize.
Early antebellum defenders of slavery acknowledged that slavery created problems for southern society. They contended, however, that slave society was better and more natural than other forms of social organization. Thomas R. Dew, William Harper, and James Henry Hammond each expressed a social philosophy in which slavery had a crucial role in preserving social order. They argued from the basis of social organicism, the idea that society should have an elite that controlled the masses. For all three men, slavery represented a system of order that helped balance the dangers of democracy. Significantly, however, all three men recognized that the slave system was not perfect, and despite their defense of slavery, argued that it was a human institution and therefore corruptible.
A model for health care utilization was applied to a sample of low income women. Demographic Predisposing, Psychosocial Predisposing, Illness Level, and Enabling indicators were examined separately for African American (n = 266), Anglo American (n = 200), and Mexican American (n = 210) women. Structural Equation Modeling revealed that for African American and Anglo American women, Illness Level, the only significant path to Utilization, had a mediating effect on Psychosocial Predisposing indicators. The model for Mexican Americans was the most complex with Enabling indicators affecting Illness Level and Utilization. Psychosocial Predisposing indicators were mediated by Illness Level and Enabling indicators which both directly affected Utilization. Implications of the results for future research are addressed.
The thermoelectric properties of bismuth telluride based thermoelectric (TE) materials are well-characterized, but comparatively little has been published on the thermomechanical properties. In this paper, dynamic mechanical analysis (DMA) and differential scanning calorimetry data for bismuth telluride based TE materials is presented. The TE materials' tan delta values, indicative of viscoelastic energy dissipation modes, approached that of glassy or crystalline polymers, were greater than ten times the tan delta of structural metals, and reflected the anisotropic nature of TE materials. DMA thermal scans showed changes in mechanical properties versus temperature with clear hysteresis effects. These results showed that the application of DMA techniques are useful for evaluation of thermophysical and thermomechanical properties of these TE materials.
