An Evaluation of the University of North Texas' "Youth Opportunities Unlimited" Program (a Compensatory Education Program for At-Risk, Secondary School Students)
Even though the Youth Opportunities Unlimited program has been in effect for ten years, there exists no current, comprehensive, effectiveness research on YOU. Such analysis is needed to determine the value of the YOU program. The purpose of this study is to evaluate the effectiveness of the YOU program. Both quantitative and qualitative research methods are used in this study. Quantitative analysis is provided through factual data collected through an alumni survey. Qualitative analysis is provided through personal opinion information obtained from YOU alumni through the survey and by personal interview. The YOU program at UNT is a successful compensatory education program that helps improve the education and the lives of America's at-risk students.

Evaluation of the Use of the Bivalves Ischadium recurvum Rafinesque, 1820 and Corbicula fluminea Muller, 1774 as Biological Indicators of Relative Water Quality in Terms of Growth and Upper Temperature Tolerance
Growth of mussels under laboratory conditions was examined under various food regimes in different water types and temperatures. Growth was less than would be useful as an indicator and comparisons with field exposures were of minimal value. The effects of organophosphates on bivalves were examined via toxicity tests, tissue concentration, and by controlling exposure through the use of physical constraints. Upper temperature tolerance of both bivalve species was examined with respect to different acclimation temperatures and organophosphate exposures. Deviations from control exposures occurred at some temperatures. Copper effectively lowered the mean heat coma temperatures of C. fluminea at some concentrations, however, chlorine exposures did not alter heat coma temperature.

An Evaluation of Two Methods of Teaching Social Studies in Junior High School
The objective of this study is to evaluate the effectiveness of two methods of teaching the social studies to junior high school pupils. An attempt has been made to ascertain the relative progress in the studying efficiency of a group of children in social studies taught by the basic-study-skills plan, as compared to that of a group of children taught by the assign-study-recite-test plan so commonly employed.
An evaluation of two performance pay systems on the productivity of employees in a certified public accounting firm.
This study examined the effects of switching from an incentive pay system solely based on productivity to a scorecard-based incentive pay system. Performance of staff and senior accountants was analyzed across three departments for a two-year baseline and a three-year intervention period. Results showed that percent of charge hour goal remained high during the study. Once the scorecard-based incentive system was implemented, performance on the other line items increased or remained at or above goal levels. Incentive payouts were generally higher under the second incentive plan than under the first for top performers. Possible explanations for data trends, weaknesses of the measures within the scorecard, measure/line item alternatives and implications for future research are also discussed.
Evaluation of virulence in wild type and pyrimidine auxotrophs of Pseudomonas aeruginosa using the eukaryotic model system Caenorhabditis elegans.
Access: Use of this item is restricted to the UNT Community.
The human opportunistic pathogen, Pseudomonas aeruginosa PAO1, has been shown to kill the nematode Caenorhabditis elegans. C. elegans has been a valuable model for the study of bacterial pathogenesis, and has reinforced the notion that common virulence and host defense mechanisms exist. Recently, the pyrimidine pathway was shown to regulate virulence levels. Therefore, mutations in the pyrimidine pathway of PAO1 showed decrease virulence in the nematode. When starving the nematode, bacterial resistance was also shown to increase. It was hypothesized that starvation induced the DAF pathway, which regulates the transcription of genes involved with the antibacterial defense mechanism. Further research will be conducted to test this theory by performing RNAi experiments for the genes functioning in the antibacterial defense mechanism.

Evaluation of zinc toxicity using neuronal networks on microelectrode arrays: response quantification and entry pathway analysis.
Murine neuronal networks, derived from embryonic frontal cortex (FC) tissue grown on microelectrode arrays, were used to investigate zinc toxicity at concentrations ranging from 20 to 2000 mM total zinc acetate added to the culture medium. Continual multi-channel recording of spontaneous action potential generation allowed a quantitative analysis of the temporal evolution of network spike activity generation at specific zinc acetate concentrations. Cultures responded with immediate concentration-dependent excitation lasting from 5 to 50 min, consisting of increased spiking and enhanced, coordinated bursting. This was followed by irreversible activity decay. The time to 50% and 90% activity loss was concentration dependent, highly reproducible, and formed linear functions in log-log plots. Network activity loss generally preceded morphological changes. 20% cell swelling was correlated with 50% activity loss. Cultures pretreated with the GABAA receptor antagonists bicuculline (40 mM) and picrotoxin (1 mM) lacked the initial excitation phase. This suggests that zinc-induced excitation may be mediated by interfering with GABA inhibition. Partial network protection was achieved by stopping spontaneous activity with either tetrodotoxin (200 nM) or lidocaine (250 mM). However, recovery was not complete and slow deterioration of network activity continued over 6 hrs. Removal of zinc by early medium changes showed irreversible, catastrophic network failure to develop in a concentration-dependent time window between 50% and 90% activity loss. Investigation of entry routes suggested the L-type but not N-type calcium channels to be the main entry pathway for zinc. Data are presented implicating the chloride channel to be an additional entry route.
Evaluation Practices of Community College Faculty Development Programs
The purpose of this quantitative study was to determine the current state of community college faculty development program evaluation and identify possible influences on evaluation practices. Data from 184 survey responses and the Integrated Postsecondary Education Data System (IPEDS) were analyzed to answer three research questions. Multiple regression was used to determine if a relationship existed between the dependent/outcome variable (evaluation utilization score) and the independent/predictor variable (accrediting agency affiliation: MSCHE, NEASC, NCA, NWCCU, SACS, and WASC) and/or control variables (institution locale, student FTE, expenses per student FTE, percent spent on instruction, and percent of full-time faculty). Results were not statistically significant, F (12, 163) = 1.176, p = .305. The mean evaluation scores were similar for all six accrediting agencies ranging from 60-69. The rural variable was statistically significant with p = .003 and alpha = .05, but it only accounted for 3.6% of the variance explained. Logistic regression was used to determine if a relationship existed between the dependent/outcome variable (use of evaluation) and the above-specified independent/predictor variable and/or control variables for six faculty development program activities. Results revealed that significant predictor variables for the use of evaluation vary based on the faculty development program activity. Statistically significant predictors were identified for two of the six activities. The percent spent on instruction variable was statistically significant for financial support for attending professional conferences (p = .02; alpha = .05). The NCA affiliation and student FTE variables were statistically significant for orientation for new faculty (p = .007; alpha = .05 and p = .027; alpha = .05 respectively). The analysis of the evaluation methods was conducted using descriptive statistics and frequencies. The most frequently used evaluation methods were questionnaire and verbal feedback. NCA was identified as having the greatest number of institutions using the most frequently used evaluation methods for four of the activities. SACS was identified as having the largest number of institutions using the greatest number of evaluation methods for five of the activities. It was discovered that accrediting agencies with policies regarding faculty development program evaluation practices were not more likely to have higher evaluation utilization scores or utilize evaluation methods more frequently than accrediting agencies without such policies. The study revealed that among community college faculty development programs evaluation practice similarities were more prevalent than differences regardless of accrediting agency affiliation. As a result of this discovery, future research should extend beyond the accrediting agency affiliation emphasis and explore additional influences on institutional decision making processes regarding community college faculty development program evaluation practices.

An Evaluative Study of Physical Education Activity Programs for Boys in Selected Junior High Schools of Texas
The problem undertaken in this study was to evaluate the activity phase of boys' physical education programs in selected junior high schools of Texas. As a result of visitation and observation in a number of public junior high schools in the capacity of supervising teacher for physical education majors, it appears that many physical education programs were little more than loosely supervised play periods. Apparently there was room for improvement of these programs but a method for making judgments and recommendations required some type of measuring device. However, an examination of several existing measuring techniques failed to reveal any one devoted to the junior high school level or one concerned primarily with the activity program. As a means of improving existing programs, it was concluded that some new form of evaluation must be designed.

Event Centrality: Debunking the “Bad Science” Myth That Self-reported Posttraumatic Growth Does Not Reflect Positive Change
Despite strong evidence supporting the existence of posttraumatic growth (PTG), some investigators question whether the construct measured by the Posttraumatic Growth Inventory (PTGI) is that of perceived growth or “actual” growth. In a replication of a recent investigation, the present study sought to refine the methodology used by employing the construct of event centrality. Due to its limited sample size, the results of this analysis did not provide strong evidence in support of the hypothesis that limiting analyses to individuals rating their trauma as high in event centrality improves the ability of the PTGI to reflect “actual” growth. However, results did support the idea that investigations of PTG conducted immediately following a trauma may be more reflective of a coping process, rather than growth. Further research is warranted to investigate the role of event centrality in posttraumatic growth, and the effect of time on the progression of growth following trauma.

Evidence for Multiple Functions of a Medicago Truncatula Transporter
Access: Use of this item is restricted to the UNT Community.
Legumes play an important role in agriculture as major food sources for humans and as feed for animals. Bioavailable nitrogen is a limiting nutrient for crop growth. Legumes are important because they can form a symbiotic relationship with soil bacteria called rhizobia that results in nitrogen-fixing root nodules. In this symbiosis, rhizobia provide nitrogen to the legumes and the legumes provide carbon sources to the rhizobia. The Medicago truncatula NPF1.7/NIP/LATD gene is essential for root nodule development and also for proper development of root architecture. Work in our lab on the MtNPF1.7/MtNIP/LATD gene has established that it encodes a nitrate transporter and strongly suggests it has another function. Mtnip-1/latd mutants have pleiotropic defects, which are only partially explained by defects in nitrate transport. MtNPF1.7/NIP/LATD is a member of the large and diverse NPF/NRT1(PTR) transporter family. NPF/NRT1(PTR) members have been shown to transport other compounds in addition to nitrate: nitrite, amino acids, di- and tri-peptides, dicarboxylates, auxin, abscisic acid and glucosinolates. In Arabidopsis thaliana, the AtNPF6.3/NRT1.1( CHL1) transporter was shown to transport auxin as well as nitrate. Atchl1 mutants have defects in root architecture, which may be explained by defects in auxin transport and/or nitrate sensing. Considering the pleiotropic phenotypes observed in Mtnip-1/latd mutant plants, it is possible that MtNPF1.7/NIP/LATD could have similar activity as AtNPF6.3/NRT1.1(CHL1). Experimental evidence shows that the MtNPF1.7/NIP/LATD gene is able to restore nitrate-absent responsiveness defects of the Atchl1-5 mutant. The constitutive expression of MtNPF1.7/NIP/LATD gene was able to partially, but not fully restore the wild-type phenotype in the Atchl1-5 mutant line in response to auxin and cytokinin. The constitutive expression of MtNPF1.7/NIP/LATD gene affects the lateral root density of wild-type Col-0 plants differently in response to IAA in the presence of high (1mM) or low (0.1 mM) nitrate. MtNPF1.7/NIP/LATD gene expression is not regulated by nitrate at the concentrations tested and MtNPF1.7/NIP/LATD does not regulate the nitrate-responsive MtNRT2.1 gene. Mtnip-1 plants have an abnormal gravitropic root response implicating an auxin defect. Together with these results, MtNPF1.7/NIP/LATD is associated with nitrate and auxin; however, it does not act in a homologous fashion as AtNPF6.3/NRT1.1(CHL1) does in A. thaliana.

Evidentiary Value of Condoms: Comparison of Durable Physical and Chemical Characteristics of Condoms
Access: Use of this item is restricted to the UNT Community.
Condom trace evidence must not be overlooked in sexual assault cases; understanding the chemical and physical characteristics of condoms is imperative if condoms are to be useful evidence. Previous research shows that condom identification is possible, but it is equally important to evaluate durability of condom residues versus time. Using FT-IR, this study examined vaginal swabs from subjects who self-sampled at intervals for up to 72 hours after having intercourse with a condom. This study investigated whether age and the stage of the menstrual cycle affected the durability of residues in the vagina over time. This study revealed that condoms containing nonoxynol-9, silicone-based lubricants, and particulates provide valuable information for identification, and that nonoxynol-9 specifically withstands the vaginal environment for up to 72 hours. Additionally, age and menstrual cycle both appeared to have an effect on the durability of residues although larger sample size is desirable.
Evocations from Childhood: Stylistic Influences and Musical Quotations in Claude Debussy's Children's Corner and La Boîte à Joujoux
Claude Debussy is considered one of the most influential figures of the late 19th century and early 20th centuries. Among the various works that he wrote for the piano, Children's Corner and La Boîte à joujoux distinguish themselves as being evocative of childhood. However, compared to more substantial works like Pelléas et Mélisande or La Mer, his children's piano music has been underrated and seldom performed. Children's Corner and La Boîte à joujoux were influenced by a series of eclectic sources, including jazz, novel "views" from Russian composers, and traditional musical elements such as folk songs and Eastern music. The study examines several stylistic parallels found in these two pieces and is followed by a discussion of Debussy's use of musical quotations and allusions, important elements used by the composer to achieve what could be dubbed as a unique "children's wonderland."

La Evolución Del Subalterno En Tres Novelas Mexicanas: La Negra Angustias, Balún Canán, Y Neonao
The subaltern is a recurrent literary figure in Mexican narrative. The objective of this thesis is to investigate three ethnic groups – indeed, subalterns – in Mexico which include: Afro-Mexicans, indigenous groups, and Filipino colonial subjects from the perspectives of the Mexican Revolution, post-revolutionary Mexico, and the conquest of the Philippines in the sixteenth century. The principal characters play crucial roles in events shaping the history and culture of Mexico and thus demonstrate their importance to the country's development while also revealing the reality of subalterns. The literary research shows that trying circumstances or a lack of self-identity were the main causes for a character to be or become a subaltern in addition to their inherent ethnic disadvantages. However, the characters who overcame their subaltern state often changed personality traits or adapted to their surroundings in order to be assimilated into the majority culture.

Evolution, Not Revolution: The Effect of New Deal Legislation on Industrial Growth and Union Development in Dallas, Texas
The New Deal legislation of the 1930s would threaten Dallas' peaceful industrial appearance. In fact, New Deal programs and legislation did have an effect on the city, albeit an unbalanced mixture of positive and negative outcomes characterized by frustrated workers and industrial intimidation. To summarize, the New Deal did not bring a revolution, but it did continue an evolutionary change for reform. This dissertation investigated several issues pertaining to the development of the textile industry, cement industry, and the Ford automobile factory in Dallas and its labor history before, during, and after the New Deal. New Deal legislation not only created an avenue for industrial workers to achieve better representation but also improved their working conditions. Specifically focusing on the textile, cement, and automobile industries illustrates that the development of union representation is a spectrum, with one end being the passive but successful cement industry experience and the other end being the automobile industry union efforts, which were characterized by violence and intimidation. These case studies illustrate the changing relationship between Dallas labor and the federal government as well as their local management. Challenges to the open shop movement in Dallas occurred before the creation of the New Deal, but it was New Deal legislation that encouraged union developers to recruit workers actively in Dallas. Workers' demands, New Deal industrial regulations, and union activism created a more urban, modern Dallas that would be solidified through the industrial demands for World War II.
The Evolution of AIDS as Subject Matter in Select American Dramas
Dramatic works from America with AIDS as subject matter have evolved over the past twenty years. In the early 1980s, dramas like Larry Kramer's The Normal Heart, William Hoffman's As Is, and Robert Chesley's Night Sweat educated primarily homosexual men about AIDS, its causes, and its effects on the gay community while combating the dominant discourse promoted by the media, government, and medical establishments that AIDS was either unimportant because it affected primarily the homosexual population or because it was attributed to lack of personal responsibility. By the mid-eighties and early nineties, playwrights Terrence McNally (Love! Valour! Compassion!)and Paul Rudnick (Jeffrey)concentrated on relationships between sero-discordant homosexual couples. McNally's "Andre's Mother" and Lips Together, Teeth Apart explored how families and friends face the loss of a loved one to AIDS. Tony Kushner's Pulitzer Prize-winning Angels in America epic represents living beyond AIDS as a powerful force. Without change and progress, Angels warns, life stagnates. Angels also introduces the powerful drugs that help alleviate the symptoms of AIDS. AIDS is the centerpiece of the epic, and AIDS and homosexuality are inextricably blended in the play. Rent, the Pulitzer Prize-winning musical by Jonathan Larson, features characters from an assortment of ethnic and social backgrounds - including heterosexuals, homosexuals, bi-sexuals, some with AIDS, some AIDS-free, some drug users - all living through the diverse troubles visited upon them at the turn of the millennium in the East Village of New York City. AIDS is not treated as "special," nor are people with AIDS pandered to. Instead, the characters take what life gives them, and they live fully, because there is "no day but today" ("Finale"). Rent's audiences are as varied as the American population, because it portrays metaphorically what so many Americans face daily - not AIDS per se, but other difficult life problems, including self-alienation. As such, Rent defies the dominant discourse because the community portrayed in Rent is the American community.
The Evolution of Capital Formation Theory
The various aspects of a social science ramify closely with one another, and so it will be necessary to inspect certain economic theories rather extensively in search of their meaningful connection with the word "capital." However, the major purpose here will be an examination of the use and potential logical use of the terms "capital" and "capital formation."
