Electromagnetic Shielding Properties of Iron Oxide Impregnated Kenaf Bast Fiberboard
The electromagnetic shielding effectiveness of kenaf bast fiber based composites with different iron oxide impregnation levels was investigated. The kenaf fibers were retted to remove the lignin and extractives from the pores in fibers, and then magnetized. Using the unsaturated polyester and the magnetized fibers, kenaf fiber based composites were manufactured by compression molding process. The transmission energies of the composites were characterized when the composite samples were exposed under the irradiation of electromagnetic (EM) wave with a changing frequency from 9 GHz to 11 GHz. Using the scanning electron microscope (SEM), the iron oxide nanoparticles were observed on the surfaces and inside the micropore structures of single fibers. The SEM images revealed that the composite’s EM shielding effectiveness was increased due to the adhesion of the iron oxide crystals to the kenaf fiber surfaces. As the Fe content increased from 0% to 6.8%, 15.9% and 18.0%, the total surface free energy of kenaf fibers with magnetizing treat increased from 44.77 mJ/m2 to 46.07 mJ/m2, 48.78 mJ/m2 and 53.02 mJ/m2, respectively, while the modulus of elasticity (MOE) reduced from 2,875 MPa to 2,729 MPa, 2,487 MPa and 2,007 MPa, respectively. Meanwhile, the shielding effectiveness was increased from 30-50% to 60-70%, 65-75% and 70-80%, respectively.
Electromagnetically Modulated Sonic Structures
Phononic crystals are structures composed of periodically arranged scatterers in a background medium that affect the transmission of elastic waves. They have garnered much interest in recent years for their macro-scale properties that can be modulated by the micro-scale components. The elastic properties of the composite materials, the contrast in the elastic properties of the composite materials, and the material arrangement all directly affect how an elastic wave will behave as it propagates through the sonic structure. The behavior of an elastic wave in a periodic structure is revealed in its transmission bandstructure, and modification of any the elastic parameters will result in tuning of the band structure. In this dissertation, a phononic crystal with properties that can be modulated using electromagnetic radiation, and more specifically, radio-frequency (RF) light will be presented.
Electron Density and Collision Frequency Studies Using a Resonant Microwave Cavity as a Probe
Electron densities and collision frequencies were obtained on a number of gases in a dc discharge at low pressures (0.70-2mm of Hg). These measurements were performed by microwave probing of a filament of the dc discharge placed coaxially in a resonant cavity operating in a TM₀₁₀ mode. The equipment and techniques for making the microwave measurements employing the resonant cavity are described. One of the main features of this investigation is the technique of differentiating the resonance signal of the loaded cavity in order to make accurate measurements of the resonant frequency and half-power point frequencies.
The Electron Emission Characteristics of Aluminum, Molybdenum and Carbon Nanotubes Studied by Field Emission and Photoemission.
The electron emission characteristics of aluminum, molybdenum and carbon nanotubes were studied. The experiments were setup to study the emission behavior as a function of temperature and exposure to oxygen. Changes in the surface work function as a result of thermal annealing were monitored with low energy ultra-violet photoelectron spectroscopy for flat samples while field emission energy distributions were used on tip samples. The change in the field emission from fabricated single tips exposed to oxygen while in operation was measured using simultaneous Fowler-Nordheim plots and electron energy distributions. From the results a mechanism for the degradation in the emission was concluded. Thermal experiments on molybdenum and aluminum showed that these two materials can be reduced at elevated temperatures, while carbon nanotubes on the other hand show effects of oxidation. To purely reduce molybdenum a temperature in excess of 750 ºC is required. This temperature exceeds that allowed by current display device technology. Aluminum on the other hand shows reduction at a much lower temperature of at least 125 ºC; however, its extreme reactivity towards oxygen containing species produces re-oxidation. It is believed that this reduction is due to the outward diffusion of aluminum atoms through the oxide. Carbon nanotubes on the other hand show signs of oxidation as they are heated above 700 ºC. In this case the elevated temperatures cause the opening of the end caps allowing the uptake of water. Oxygen exposure experiments indicate that degradation in field emission is two-fold and is ultimately dependent on the emission current at which the tip is operated. At low emission currents the degradation is exclusively due to oxidation. At high emission currents ion bombardment results in the degradation of the emitter. In between the two extremes, molybdenum tips are capable of stable emission.
Electron-Ion Time-of-Flight Coincidence Measurements of K-K Electron Capture, Cross Sections for Nitrogen, Methane, Ethylene, Ethane, Carbon Dioxide and Argon (L-K) Targets
Protons with energies ranging from 0.4 to 2.0 MeV were used to measure K-shell vacancy production cross sections (oVK) for N_2, CH_4, C_2H_4, C_2H_6, and CO_2 gas targets under single collision conditions. An electron-ion time-of-flight coincidence technique was used to determind the ration of the K-K electron capture cross section, OECK, to the K-vacancy production cross section, oVK. These ratios were then combined with the measured values of oVK to extract the K-K electron capture cross sections. Measurements were also made for protons of the same energy range but with regard to L-shell vacancy production and L-K electron capture for Ar targets. In addition, K-K electron capture cross sections were measured for 1.0 to 2.0 Mev 42He^_ ions on CH_4.

The Electronic Ranch: the Information Environment of Cattle Breeders
The present study was a longitudinal analysis of the information needs of Red Angus cattle breeders and their use of networked information services. It was based on two surveys. The first, conducted in 1995--96, polled all 1067 ranches of the Red Angus Association of America. Responses from 192 Red Angus breeders were used to determine the value of different information types and to evaluate perceptions of the greatest barriers to the adoption of network information services. The second survey, mailed to 41 Red Angus breeders in 1998, focused on early adopters and likely users of network services. Responses from 15 breeders were used to evaluate perceptions of the greatest barriers to the effective use of Web-based information services.
Electronic Sound Analysis with Hardware System and Remote Internet Display
Currently, standards from government agencies such as the National Institute for Occupation Safety and Health exist to aid in safeguarding individuals’ capacity for hearing, but only in factory settings in which large machines often produce loud levels of sound. Neglecting the fact that these preventative measures are only in place in the most limited of settings, no system currently exists to observe and report sound exposure levels in a manner timely or easily recognizable enough to adequately serve its purpose of hearing conservation. Musicians may also incur significant levels of risk for hearing loss in their day-to-day rehearsals and concerts, from high school marching bands to university wind bands. As a result, music school accrediting organizations such as the National Association of Schools of Music and even the European Union have begun taking steps meant to determine the risks associated with music. To meet these goals and improve upon current technologies, a system has been developed that electronically records sound levels utilizing modern hardware, increases the speed of reporting by transmitting data over computer networks and the Internet, and displays measures calculated from these data in a web browser for a highly viewable, user-friendly interface.
The Electronic Spectrum of (-)-S-(pS)-2,5,3',6'-Tetrahydro-2.2-Paracyclophane-2-Carboxylic Acid
A new, efficient route was used in the synthesis of [2.2]-paracyclophane-2-carboxylic acid. The acid as then resolved and the Birch reduction performed yielding one enantiomer of tetrahydro-[2.2]-paracyclophane-2-carboxylic acid. The ultraviolet spectrum of tetrahydro-[2.2]-paracyclophane- 2-carboxylic acid in isopenthane shows one absorption at 206 nm (Emax = 5,271). There are three bands observed in the circular dichroism spectrum in isopentane at 236 nm ([] = 1.8 X 104), 201 nm ([0] = -16 X 104) and a positive band indicated below 180 nm but not observed. The bands were assigned and possible reasons for the occurrence of a mr'r* transition at unexpectedly long wavelengths are discussed.

Electrostatic Effects in III-V Semiconductor Based Metal-optical Nanostructures
The modification of the band edge or emission energy of semiconductor quantum well light emitters due to image charge induced phenomenon is an emerging field of study. This effect observed in quantum well light emitters is critical for all metal-optics based light emitters including plasmonics, or nanometallic electrode based light emitters. This dissertation presents, for the first time, a systematic study of the image charge effect on semiconductor–metal systems. the necessity of introducing the image charge interactions is demonstrated by experiments and mathematical methods for semiconductor-metal image charge interactions are introduced and developed.
Electrostatic Mechanism of Emission Enhancement in Hybrid Metal-semiconductor Light-emitting Heterostructures
III-V nitrides have been put to use in a variety of applications including laser diodes for modern DVD devices and for solid-state white lighting. Plasmonics has come to the foreground over the past decade as a means for increasing the internal quantum efficiency (IQE) of devices through resonant interaction with surface plasmons which exist at metal/dielectric interfaces. Increases in emission intensity of an order of magnitude have been previously reported using silver thin-films on InGaN/GaN MQWs. the dependence on resonant interaction between the plasmons and the light emitter limits the applications of plasmonics for light emission. This dissertation presents a new non-resonant mechanism based on electrostatic interaction of carriers with induced image charges in a nearby metallic nanoparticle. Enhancement similar in strength to that of plasmonics is observed, without the restrictions imposed upon resonant interactions. in this work we demonstrate several key features of this new interaction, including intensity-dependent saturation, increase in the radiative recombination lifetime, and strongly inhomogeneous light emission. We also present a model for the interaction based on the aforementioned image charge interactions. Also discussed are results of work done in the course of this research resulting in the development of a novel technique for strain measurement in light-emitting structures. This technique makes use of a spectral fitting model to extract information about electron-phonon interactions in the sample which can then be related to strain using theoretical modeling.

Elementary Math Achievement in Texas: What is Working?
Elementary math teachers (76) from selected Texas schools that included Grade 5 responded to an online self-report survey with respect to school-level factors that may be associated with student math achievement. Questions on the survey focused on school-level factors related to math, campus leadership, integration of technology in the math classroom, teacher expectations, utilization of student data in decision-making and professional development. The schools included in the study were rated as Acceptable or Exemplary schools by the Texas Education Agency for three-consecutive years (2007-2010). Logistic regression techniques were used to analyze the data and 11 questions out of 45 were analyzed to determine the odds ratio. Factors that were correlated with being an Exemplary campus were teacher certification routes, not benchmarking student progress, implementation of response to intervention (RTI), classroom management focus (equally divided between student and teacher centered) within the classroom, and technology integration. The results indicated that at the .05 level of probability, the only factor that met that level of significance was full implementation of RTI.
Elementary music teachers instructing English language learners: Reflection on practice.
This qualitative study investigated four monolingual, English-only speaking Caucasian elementary music teachers and their reflections regarding instruction of English language learners (ELL). The purpose of this multiple case study was to investigate the teaching practice and curricular decisions of elementary music teachers who instruct Hispanic ELL students. The investigation was conducted during a nine-week period, and data collection included classroom observations, phenomenological interviewing, and teacher audio journals. None of the teachers had prior education or pre-service preparation in teaching music to ELL students. The major theoretical base from which the study was developed was the reflective teaching theory of Donald Schön (1983). The main research question was: "What are the participating teachers' reflections about their curricular and pedagogical decisions when teaching ELL students?" Following a description of the elementary music teachers' reflections on practice with ELL students, the study revealed that the majority of elementary music teachers had a lack of preparation and ELL music curriculum, and negative perceptions of the placement program for ESL students. Despite these factors, the teachers made attempts to include ELL students in all music activities. This study showed that while one teacher accommodated specifically for the ELL students' learning, three out of four teachers did not. This study also suggests that music is a subject by which strong interactions between peers, opportunity for language expansion, and other factors occur which have positive correspondence to recommended ELL instructional strategies. A cross-case analysis revealed that the life history and experience of the elementary music teachers had an influence on the teachers' awareness of ELL students. The analysis suggests a relationship between teacher awareness and accommodation. The study also recognized the need for further inquiry regarding ELL students and issues related to their school placement. This study has implications for music education research including suggestions for music ...
Elementary Pre-service Teachers’ Perceptions and Experiences of Mathematics Intervention and Response to Intervention Practices
Response to intervention has become a widely implemented early intervention and pre-referral program in many schools due to the reauthorization of the 2004 Individuals with Disabilities Education Act. Limited studies exist that validate how teacher preparation programs are preparing the next generation of teachers to assess students, apply early academic interventions, monitor progress, and make educational decisions for students with learning difficulties as part of an RTI program. The purpose of this study was to examine elementary pre-service teachers’ perceptions and experiences in a mathematics intervention project (MIP), as part of a university mathematics methods course as related to RTI practices. Data were collected from multiple sources, including: Seidman’s three-step interview series with pre-service participants and course instructors, document analysis of the Mathematics Interactions Project (MIP) students’ responses, mathematics methods course syllabi, and observations of the mathematics methods course instruction. Haskell’s transfer theory was used as the framework from which to analyze the data. It was assumed that if a majority of the 11 principles of meaningful transfer were addressed, higher levels of transfer from university instruction to intervention instruction would be observed during the MIP. Findings indicate differences in RTI understanding according to elementary education degree plan. Candidates in the English as a Second Language (ESL) program did not demonstrate a strong foundational understanding of RTI, evidenced by a lower level of transfer about RTI. Alternately, pre-service teachers in the special education degree plan had a stronger foundational knowledge of RTI, discussed how RTI learning was supported, and had more experiences to implement RTI (principles 1, 7, and 9). Pre-service teachers in the Special Education (SPED) certification degree plan demonstrated a higher level of transfer since more of the principles were met; this was foundational in Haskell’s transfer theory. Implications are that elementary education programs, and particularly projects such ...
Elementary School Climate Factors and Personality and Status Variables Associated with School Library Media Specialists Chosen by Classroom Teachers for Cooperation on Instructional Problems
This study investigated relationships between the extent to which elementary classroom teachers tend to choose school library media specialists for cooperation on instructional problems and several school climate and faculty related characteristics including the general academic effectiveness of the school, the overall cohesion and cooperativeness of the teaching faculty on instructional matters, and the propensity of the group and individual faculty to seek cooperation to solve instructional problems. The instructional choice status of the school library media specialist was also studied in relation to various individual personality factors, as measured by Cattell's 16 Personality Factor Questionnaire, as well as school media specialist status variables including degreed or non-degreed status, total years of experience as a school library media specialist, years of experience on campus as a school library media specialist, and total number of years of experience in the field of education. The instructional status of the school library media specialist was also examined in relationship to the size of the school served. The study included 1,079 elementary classroom teachers and thirty-nine school library media specialists from thirty-nine Texas elementary schools similar in important wealth, size, and student demographic characteristics. Twenty of the schools ranked in the bottom 25% of all schools in the state as to how well their students performed on the 1988 Texas Educational Assessment of Minimum Skills (TEAMS) test. Nineteen schools ranked among the top 25%of all schools in the state in academic effectiveness. As compared to the low academic schools, the high academic schools were found to be significantly more instructionally cohesive, and classroom teachers in those schools were significantly more disposed to choose the school library media specialist to cooperate with them on instructional problems. No significant relationships were discovered between the instructional choice status of the school media specialist and his or her ...
Elementary Students' Critical Examination of Characters in Children's Literature Depicting Social Justice
Despite the ruling of Brown vs. The Board of Education of Topeka, segregation in schools is still quite visible with suburban schools educating a student body of more than 70% White and urban schools comprised of mostly Black, Hispanic, and Asian students. Ideally, a school should dispel social and structural inequities through curriculum and quality resources, but fallibly, schools continue to be the vehicles to maintaining the status quo. Students who develop critical awareness and cultivate a critical literacy stance can become agents of change toward a more democratic society. In the current study, urban upper-elementary-age students were asked to engage in a critical literacy event by critically examining the power positions of characters in books that depict historical social injustice. The six female participants met in several sessions to read books and a newspaper article, use a critical reader response tool, and then engage in critical conversations about the books' characters. Their dialogue was recorded and analyzed using a critical discourse qualitative methodology. The findings show that older elementary students are capable of seeing multiple perspectives of an issue and can explain characters' power from born from privilege and fueled by fear and how a shift in power may occur through solidarity. The findings suggest school curriculum enhanced by media narrows the students' view of discrimination as being targeted mostly towards African-Americans, but those experiences through literature have the potential to expand the students' views to include other cultural groups. Subsequently, there is a need for broader teacher preparation using books that enhance students' views of social injustice.
Elementary Teacher Attrition and Factors of Organizational Climate
As the United States faces a critical teacher shortage, it is important to examine all factors that may contribute to the revolving door of teacher attrition. This study explored the climate of elementary schools to determine if there was a correlation between teacher attrition and school organizational climate. Three basic research questions were addressed: 1) Is there a relationship between school organizational climate and teacher attrition? 2) Is a change in campus leadership related to school organizational climate? 3) Is there a relationship between a change in campus leadership and teacher attrition? Thirty-seven elementary schools were examined in terms of their individual teacher attrition rates and their climate survey scores. The data utilized in this study came from one school district's climate survey and teacher attrition rates for the 2000-2001 school year. The findings of this study indicate that factors of organizational climate may predict teacher attrition rates. Specifically, instructiona support may be related to teacher attrition. Major components of instructional support include principal behaviors, respect for teaching and learning, and communication with administrators. Teacher attrition was not related to principal experience. Also, principal experience was not related to factors of school organizational climate.

The Elements of Jazz Harmony and Analysis
This study develops a method for analyzing jazz piano music, primarily focusing on the era 1935-1950. The method is based on axiomatic concepts of jazz harmony, such as the circle of fifths and root position harmonies. 7-10 motion between root and chordal seventh seems to be the driving force in jazz motion. The concept of tritone substitution leads to the idea of a harmonic level, i.e., a harmony's distance from the tonic. With this method in hand, various works of music are analyzed, illustrating that all harmonic motion can be labelled into one of three categories. The ultimate goal of this analytic method is to illustrate the fundamental harmonic line which serves as the harmonic framework from which the jazz composer builds.

Elements of Shamanic Mythology in E. T. A. Hoffman's Romantic Conception of Music
The musicians in E. T. A. Hoffmann's tales and essays demonstrate traits remarkably similar to those of shamans. Hoffmann uses the same imagery to describe the journey of the composer into the "realm of dreams," where he receives inspiration, as the shaman uses to describe the spirit world to which he journeys via music. Hoffmann was a major force in changing the 18th-century view of music as an "innocent luxury" to the 19th-century idea of music as a higher art. As a German Romantic,author, he subscribed to the idea championed by the Schlegels that true poetry is based on myth. In this thesis, Hoffmann's writings are compared with shamanic mythology to demonstrate a similarity beyond mere coincidence, without drawing conclusions about influence.

Elements of Verismo in Selected Operas of Giuseppe Verdi
In music, the term verismo usually refers to a realistic or naturalistic movement in Italian operas of the late nineteenth century. From the dawn of Italian opera four features have been manifested--umanita (humanism), sincerity (sincerity), passione (passion), effetto (not only theatrical effect but the supreme dramatic moment). The elements of verismo are among the characteristics present in the operas of Giuseppe Verdi where they reached a zenith of development. It is upon these veristic aspects, as identified in the second chapter, that the operas Cavalleria Rusticana and Pagliacci were based. Rigoletto, Il Trovatore, and La Traviata richly exhibit these elements of verismo which have been identified in the fourth chapter.

Elicitation of Protein-Protein Interactions from Biomedical Literature Using Association Rule Discovery
Extracting information from a stack of data is a tedious task and the scenario is no different in proteomics. Volumes of research papers are published about study of various proteins in several species, their interactions with other proteins and identification of protein(s) as possible biomarker in causing diseases. It is a challenging task for biologists to keep track of these developments manually by reading through the literatures. Several tools have been developed by computer linguists to assist identification, extraction and hypotheses generation of proteins and protein-protein interactions from biomedical publications and protein databases. However, they are confronted with the challenges of term variation, term ambiguity, access only to abstracts and inconsistencies in time-consuming manual curation of protein and protein-protein interaction repositories. This work attempts to attenuate the challenges by extracting protein-protein interactions in humans and elicit possible interactions using associative rule mining on full text, abstracts and captions from figures available from publicly available biomedical literature databases. Two such databases are used in our study: Directory of Open Access Journals (DOAJ) and PubMed Central (PMC). A corpus is built using articles based on search terms. A dataset of more than 38,000 protein-protein interactions from the Human Protein Reference Database (HPRD) is cross-referenced to validate discovered interactive pairs. A set of an optimal size of possible binary protein-protein interactions is generated to be made available for clinician or biological validation. A significant change in the number of new associations was found by altering the thresholds for support and confidence metrics. This study narrows down the limitations for biologists in keeping pace with discovery of protein-protein interactions via manually reading the literature and their needs to validate each and every possible interaction.
The Elimination of Cigarette Broadcast Advertising: A Model for Analysis and Prediction
The problem with which this investigation is concerned is that of determining whether or not the history of cigarette advertising in broadcasting developed a pattern from which a model could be abstracted and applied to other product advertisements deemed "controversial" in broadcasting. The history of broadcast cigarette advertising is analyzed in an attempt to abstract a model, The .assumption is made that this model could be capable of predicting future regulation or elimination of broadcast advertising of controversial products.
Elimination of Cigarette Smoking, Employing a New Aversive Conditioning Procedure
The study was designed to find a response on the behavioral level that would be an effective index across subjects for determining when conditioned aversive suppression of a response had been achieved. Ten male volunteers received shock during trials in which they had to smoke. Half of the subjects received a brief but more intense shock when they stopped smoking during a trial. A comparison of these subjects to the others showed their average amount of smoking suppression in pre- and post-treatment rates to be significantly (P < .025) greater. In addition, these subjects showed conditioned emotional responding. It was concluded that this behavioral level response was an effective index for determining when suppression of smoking would occur.
Elimination of Stereotyped Behavior, Employing Contingent Withdrawal and Representation of a Positively Reinforcing Stimulus
An attempt was made in this study to eliminate the body rocking behavior of a twenty-three-year-old totally blind male, individual, presently classified as moderately retarded. Consequences were placed upon, rocking behavior in seven experimental phases, employing time-out from a positively reinforcing stimulus as a punisher. More specifically, apparatus were designed in such a manner that rocking would result in elimination of the auditory and visual portion of a television, and in a later phase, the auditory portion of a transistor radio.
Elizabeth Barrett Browning: Quest for the Father
This dissertation explores Elizabeth Barrett's dependency on the archetypal Victorian patriarch. Chapter I focuses on the psychological effects of this father-daughter relationship on Elizabeth Barrett. Chapter II addresses Barrett's acceptance of the conventional female role, which is suggested by the nature and the situation of the women she chooses to depict. These women are placed in situations where they can reveal their devotion to family, their capacity for passive endurance, and their wish to resist. Almost always, they choose death as an alternative to life where a powerful father figure is present. Chapter III concentrates on the highly sentimental images of women and children whom Barrett places in a divine order, where they exist untouched by the concerns of the social order of which they are a part. Chapter IV shows that the conventional ideologies of the time, society's commitment to the "angel in the house," and the small number of female role models before her increase her difficulty to find herself a place within this order. Chapter V discusses Aurora Leigh's mission to find herself an identity and to maintain the connection with her father or father substitute. Despite Elizabeth Barrett's desire to break away from her paternal ties and to establish herself as an independent woman and poet, her unconditional loyalty and love towards her father and her tremendous need for his affection, and the security he provides restrain her resistance and surface the child in her.
Elizabeth Bishop in Brasil: An Ongoing Acculturation
Elizabeth Bishop (1911–1979), one of the foremost modern American poets, lived in Brasil during seventeen-odd years beginning in 1951. During this time she composed the poetry collection Questions of Travel, stand-alone poems, and fragments as well as prose pieces and translations. This study builds on the work of critics such as Brett Millier and Lorrie Goldensohn who have covered Bishop’s poetry during her Brasil years. However, most American critics have lacked expertise in both Brasilian culture and the Portuguese language that influenced Bishop’s poetry. Since 2000, in contrast, Brasilian critic Paulo Henriques Britto has explored issues of translating Bishop’s poetry into Portuguese, while Maria Lúcia Martins and Regina Przybycien have examined Bishop’s Brasil poems from a Brasilian perspective. However, American and Brasilian scholars have yet to recognize Bishop’s journey of acculturation as displayed through her poetry chronologically or the importance of her belated reception by Brasilian literary and popular culture. This study argues that Bishop’s Brasil poetry reveals her gradual transformation from a tourist outsider to a cultural insider through her encounters with Brasilian history, culture, language, and politics. It encompasses Bishop’s published and unpublished Brasil poetry, including drafts from the Elizabeth Bishop Papers at Vassar College. On a secondary level, this study examines a reverse acculturation in how Brasilian popular and literary communities have increasingly focused on Bishop since her death, culminating in the 2013 film, Flores Raras (Reaching for the Moon in English). Understanding this extremely rare and sustained intercultural junction of Bishop in Brasil, a junction that no American poet has made since, adds a crucial angle to twentieth-first century transnational literary perspectives.

The Elusive Mother in William Faulkner's Major Yoknapatawpha Families
Families in much of William Faulkner's Yoknapatawpha fiction are built upon traditional patriarchal structure with the father as head and provider and the mother or mother figure in charge of keeping the home and raising the children. Even though the roles appear to be clearly defined and observed, the families decline and disintegrate.
Embedded monitors for detecting and preventing intrusions in cryptographic and application protocols.
There are two main approaches for intrusion detection: signature-based and anomaly-based. Signature-based detection employs pattern matching to match attack signatures with observed data making it ideal for detecting known attacks. However, it cannot detect unknown attacks for which there is no signature available. Anomaly-based detection builds a profile of normal system behavior to detect known and unknown attacks as behavioral deviations. However, it has a drawback of a high false alarm rate. In this thesis, we describe our anomaly-based IDS designed for detecting intrusions in cryptographic and application-level protocols. Our system has several unique characteristics, such as the ability to monitor cryptographic protocols and application-level protocols embedded in encrypted sessions, a very lightweight monitoring process, and the ability to react to protocol misuse by modifying protocol response directly.
Embedded Within Landscapes: Agrarian Philosophy and Sustainable Agriculture
Small-scale, conservation-based agrarianism provides a model for sustainable human habitation within heterogeneous landscapes. Thoreau's Transcendentalism and the historical roots of American Agrarianism are explored as influences for wilderness preservation and the New Agrarian movement. Idealizing a distant wilderness too often means overlooking the ecological and socio-economic environment where people live. Middle landscapes between nature and culture, or between wilderness and cities, can either increase or reduce ecological and social functioning within the landscape matrix. Managing middle landscapes by agrarian principles helps move both nature and culture towards ecological, economic, and social sustainability. This thesis ends with a discussion of agrarian themes, such as supporting decentralized local economies and increasing community connectivity, applied in urban, rural, and wilderness landscapes.
Embracing Equality: Texas Baptists, Social Christianity, and Civil Rights in the Twentieth Century
Texas Baptists in the twentieth century struggled to overcome prejudice and embrace racial equality. While historians have generally agreed that Baptist leadership in Texas was more progressive in regard to race relations than that of other southern states, Texas Baptists acquiesced to calls for racial justice with great difficulty. This study seeks to analyze the relationship between Texas Baptists' understanding of social Christianity and their views of racial equality. Furthermore, this study seeks to examine the extent to which white Texas Baptists actually changed their racial views and incorporated African Americans into their church services following the civil rights movement. An analysis of the racial transformation of one of Texas' most famous Baptists, W. A. Criswell, and the history of the Christian Life Commission, which is the ethical arm of the Baptist General Convention of Texas, provides great insight in to the racial progress made by Texas Baptists in the twentieth century. As Texas Baptists enter the twenty-first century and encounter a large and growing Hispanic population, the findings of this study will render aide to those who wish to embark on a new future by learning from the mistakes of their past.
Emergence, Growth, Drift and Microdistribution of Stoneflies (Plecoptera) in an Ozark Foothills Stream, Delaware County
Adult stonefly emergence, nymphal growth, drift and microdistribution were examined in Battle Branch, a secondorder, spring-fed stream, from November, 1982 to May, 1984. Adults of 22 species emerged successionally, with specific adults present every month. Searching emergent objects and the stream margin was best for collection of winter and early spring emerging species. Sweeping the streamside and light trapping were most efficient for late spring and summer emerging species. Nymphal growth for nine abundant species generally fit double log or semilog models. Drift was low, but did show a post-sunset pulse. Generally, leaf material was found to be significantly related (p<O.001) to density, diversity and biomass of stoneflies in Battle Branch.
