Anne Brontë's New Women: Agnes Grey and The Tenant of Wildfell Hall as Precursors of New Woman Fiction
Access: Use of this item is restricted to the UNT Community.
Anne Brontë's Agnes Grey and The Tenant of Wildfell Hall were published more than forty years before the appearance of the feminist type that the Victorians called the “New Woman;” yet, both novels contain characteristics of New Woman fiction. By considering how Brontë's novels foreshadow New Woman fiction, the reader of these novels can re-enact the “gentlest” Brontë as an influential feminist whose ideology informed the construction of the radical New Woman. Brontë, like the New Woman writers, incorporated autobiographical dilemmas into her fiction. By using her own experiences as a governess, Brontë constructs Agnes Grey's incongruent social status and a morally corrupt gentry and aristocracy through her depiction of not only Agnes's second employers, the Murrays, but also the morally debauched world that Helen enters upon her marriage to Arthur Huntingdon in The Tenant of Wildfell Hall. Moreover, Brontë incorporates her observations of Branwell's alcoholism and her own religious beliefs into The Tenant of Wildfell Hall. Although Brontë's novels contain autobiographical material, her heroines are fictional constructions that she uses to engage her readers with the woman question. Brontë accomplishes this engagement through her heroines' narrative re-enactments of fictional autobiographical dilemmas. Helen's diary and Agnes's diary-based narrative produce the pattern of development of the Bildungsroman and foreshadow the New Woman novelists' Kunstlerromans. Brontë's heroines anticipate the female artist as the protagonist of the New Woman Kunstlerromans. Agnes and Helen both invade the masculine domain of economic motive and are feminists who profess gender definitions that conflict with dominant Victorian ideology. Agnes questions her own femininity by internalizing the governess's status incongruence, and Helen's femininity is questioned by those around her. The paradoxical position of both heroines anticipates the debate about the nature and function of art in which the New Woman writers engaged. Through her reconciliation of the aesthetic and the political, Brontë, like the New Woman novelists who will follow, explores the contradiction between art and activism.

Political Identity of First-Year College Students: An Analysis of Student Characteristics Using Cooperative Institutional Research Program (CIRP) Data
This quantitative study utilized secondary self-reported data from the 2008 administration of the Cooperative Institutional Research Program (CIRP) Freshman Survey from two Texas public universities to investigate the pre-college demographic, academic, attitude, behavioral, and familial factors that may relate to students' self-reported political identities. The study design was correlational regarding the relationship of the demographic, academic, attitude, behavioral, and familial independent variables to the dependent variable of the students' political identities. ANOVA main effects for the independent variables were calculated, and statistical significance required the p < .05 level. The statistically significant demographic factors were native English-speaking status; enrollment status; citizenship status; religious preference; and race. The statistically significant academic factor was intended major. The statistically significant attitude factors were opinions regarding social issues such as criminal rights; abortion rights; the death penalty; the legalization of marijuana; homosexual relationships and same-sex marriage; racial discrimination; income taxes; affirmative action; military spending and voluntary military service; gun control; the environment; national health care; immigration; personal success; political dissent; and free speech. Other statistically significant attitude factors related to personal goals of making artistic and scientific contributions; being politically influential and politically knowledgeable; raising a family; participating in environmental programs and community action programs; developing a life purpose; promoting racial understanding; and promoting cultural understanding. The statistically significant behavioral factors were the frequency with which students participated in activities such as attending religious services; smoking; feeling overwhelmed or depressed; playing a musical instrument; discussing politics; and being involved in political campaigns. Other statistically significant behavioral factors were the frequency with which students participated in critical thinking activities such as using logical arguments to support their opinions; seeking alternative solutions to problems; researching scientific articles; exploring topics of personal interest; and accepting mistakes. The statistically significant familial factors were the religious preferences of the students' fathers and mothers. The results can give insight into the political characteristics of the students with whom student affairs professionals work. They can be used to inform the planning and implementation of educational programs that aid in students' political identity development.

Virulence Factor Production in PyrE Mutants of Pseudomonas Aeruginosa
It has been shown previously in our lab that mutations in the pyrimidine pathway reduced the ability of Pseudomonas aeruginosa to produce virulence factors. Knockout mutations in pyrB, pyrC and pyrD genes of the pyrimidine pathway showed that virulence factor production was decreased. Pyoverdin, pyocyanin, hemolysin, iron chelation, motility, and adherence are all considered virulence factors. Here I further investigate the effects of mutations in the pyrimidine pathway by studying a pyrE mutant. I studied the effect of the pyrE mutation on the production of the above virulence factors. Just like the effect of pyrB, pyrC and pyrD mutations,the pyrE mutation also showed that the bacteria were deficient in producing virulence factors when compared to the wild type. The broader impact of this research would be the possibility of finding drugs that could treat patients infected with P. aeruginosa and possibly extend the lives of chronically infected patients with cystic fibrosis.
The Determinants and Consequences of Empathic Parenting: Testing an Expansion of Belsky's Model of Parenting Using SEM
An understanding of factors that enhance empathic parenting behaviors is of considerable importance to the study of child development and to the development of parenting interventions to promote child adjustment. Moreover, gaining a better understanding of the factors that predict empathic parenting with older children is of interest since most research examining parental empathy focuses on infants. These were the goals of the current study. Guided by Belsky's 1984 process model of the determinants of parenting that impact child development, an expanded model of the determinants of parenting is proposed that includes various parent, child, and contextual factors of influence. Using data from a community sample, a partial least squares path analysis approach was employed to test the model's strength in predicting empathically attuned parenting with children ages 5 to 10 years and, ultimately, the child's psychoemotional functioning. Results support the expanded model; however, a reduced model was found to be superior and revealed unique relationships between the determinants of parenting. Specifically, a parent's psychoemotional functioning and childrearing beliefs and attitudes were found to be critical to the parent's ability to engage in empathic parenting behaviors. Other parent factors such as the parent's developmental history of abuse, maladaptive personality traits, and age, along with contextual factors and child characteristics, were found to influence parenting only indirectly through their impact on the parent's level of psychoemotional distress or childrearing beliefs and attitudes. Ultimately, the current findings support Belsky's claim that parent factors are the strongest predictors of empathic parenting. Implications of these findings are many. The results highlight the importance of assessing a parent's childrearing beliefs and attitudes and level of distress in conjunction with characteristics of the child when a family comes in for treatment. Moreover, the results identify many points of intervention to stopping the cycle of abuse.
A Comparative Analysis of the 1915 and 1919 Versions of Symphony No. 5 in E-flat Major, op. 82 by Jean Sibelius
The initial composition of the Fifth Symphony in E-flat Major, Op. 82 was undertaken as a commission to celebrate the composer's fiftieth birthday. Unhappy with the initial efforts, two revisions were then performed; the first was in 1916 and the final revision in 1919. Despite the larger form of the work seeming to have been changed between the 1915 and 1919 versions, the smaller gestures of thematic expression in both versions remained similar. On the surface, it had appeared that the composer had eliminated a movement, changing the 1919 version into a three movement form. This view was not challenged by the composer at the time, and since the earlier versions had either been withdrawn or destroyed, there was no way to compare the original efforts to the final product until recently. In comparing the 1919 version to the original, a definite strong parallel can be seen between the two - despite the changes to form, rearrangement of melodic material, and the seemingly different number of movements. However, the parallel is enough that the 1915 version can be a guide to classifying the 1919 version, an act that has eluded many scholars since the 1920s. Most importantly, comparing the two versions shows that the 1919 version is not a three movement form at all; it is a four movement form that is obscured by the connection of the first and second movements by a thematic bridge that contains elements from both movements, but is not placed within either structure.
The Effects of Jackpots on Responding and Choice in Two Domestic Dogs
The current study investigated the impact of delivering a jackpot on response rate and response allocation in two domestic dogs. For the purpose of this research, a jackpot was defined as a one-time, within-session increase in the magnitude of reinforcement. Two experiments were conducted to investigate the effects of delivering a jackpot in both single-operant and concurrent schedule procedures. Experiment 1 investigated the impact of a one-time, within-session increase in the magnitude of reinforcement on response rate in a single-operant procedure. Results of Experiment 1 showed no clear change in response rate after the delivery of the jackpot. Experiment 2 investigated the impact of a one-time, within-session increase in the magnitude of reinforcement on response allocation in a concurrent schedule procedure. Results of Experiment 2 showed an increase in response allocation to the jackpotted contingency in both subjects. These results suggest that a jackpot, as defined here, has no effect in single-operant procedures while having an effect in concurrent schedule procedures. These effects are similar to those reported in the magnitude of reinforcement literature.
Maleic anhydride grafted polypropylene coatings on steel: Adhesion and wear.
Polymeric coatings are being used in a growing number of applications, contributing to protection against weather conditions and localized corrosion, reducing the friction and erosion wear on the substrate. In this study, various polypropylene (PP) coatings were applied onto steel substrates by compression molding. Chemical modification of PP has been performed to increase its adhesion to metallic surfaces by grafting of maleic anhydride (MAH) onto PP in the presence of dicumyl peroxide (DCP). Influence of different concentrations of MAH and DCP on the properties of resulting materials have been examined. The coated steel samples are characterized by scanning electron microscopy (SEM), shear adhesion testing, FTIR and tribometry. The coatings with 3 wt. % MAH have shown the maximum adhesion strength due to maximum amount of grafting. The wear rates increased with increasing the amount of MAH due to simultaneous increase in un-reacted MAH.

An Assessment of Undergraduate Course Syllabi in the Departments of English at Universities in Taiwan
This exploratory, qualitative research explored the extent that course syllabi in the Departments of English in 13 public and 9 private universities in Taiwan reflect the inclusion of syllabus components to promote learning as recommended in the literature in the United States. Research questions included: what components can be inferred from the literature in the U.S. for the recommended components of a course syllabus, for the components for a learning-centered syllabus, and for a model to analyze Bloom's cognitive level of learning? And when these are applied to analyze course syllabi in English courses, are syllabi in these universities congruent with the models? The research identified and analyzed 235 course syllabi from the core courses listed online at these universities. The findings indicated that these syllabi are highly congruent with the syllabus components template; 68% of the syllabi included seven or more of the ten components. Additionally, these syllabi reflect medium congruency with the learning-centered syllabus template. Verbs used in objectives and learning outcomes in different English courses indicate different levels of cognitive learning goals as identified by Bloom's cognitive domain. Additional findings indicate that there was no difference in inclusion of components based on where faculty earned their doctoral degree. This research assumed similarities between higher education in Taiwan and the U.S., conclusions indicate that the course syllabi in Departments of English in Taiwan are congruent with the models recommended in the literature in the U.S.
A Performer's Analysis of Dominick Argento's Miss Havisham's Wedding Night
Dominick Argento's Miss Havisham's Wedding Night is the least explored of his artistic output. A monodrama in one act for soprano, Miss Havisham's Wedding Night contains some of Argento's most beautiful and challenging music of his compositional output. The purpose of a detailed analysis of the structure and content of Argento's Miss Havisham's Wedding Night is to facilitate the solo vocal performer's interpretation. Argento's setting of Miss Havisham's Wedding Night is unique in that he musically translates the manic psychological state of the literary character. Argento structured the one act opera in such a manner that the music would illuminate the text and the audience might connect with the unstable psychological episodes and outbursts demonstrated by Miss Havisham. To that end, each section and phrase has its own psychological motivation, which in turn demands a varied musical and dramatic interpretation. Utilizing selected scenes from Miss Havisham's Wedding Night, the researcher will analyze Argento's musical manifestation of Dickens's literary work. This research will include an investigation into the manner in which Argento uses the shape of melody and the musical phrase along with the harmonic materials to enhance the text and dramatic content. The author will explore the musical nuances Argento incorporates in an effort to develop and portray Miss Havisham's psychological state. Through an analysis of the orchestral writing the author will show how Argento's aesthetic balance between the music and text represents the emotional and psychological implications of the monodrama.

Optimal design of Dutch auctions with discrete bid levels.
Access: Use of this item is restricted to the UNT Community.
The theory of auction has become an active research area spanning multiple disciplines such as economics, finance, marketing and management science. But a close examination of it reveals that most of the existing studies deal with ascending (i.e., English) auctions in which it is assumed that the bid increments are continuous. There is a clear lack of research on optimal descending (i.e., Dutch) auction design with discrete bid levels. This dissertation aims to fill this void by considering single-unit, open-bid, first price Dutch auctions in which the bid levels are restricted to a finite set of values, the number of bidders may be certain or uncertain, and a secret reserve price may be present or absent. These types of auctions are most attractive for selling products that are perishable (e.g., flowers) or whose value decreases with time (e.g., air flight seats and concert tickets) (Carare and Rothkopf, 2005). I began by conducting a comprehensive survey of the current literature to identify the key dimensions of an auction model. I then zeroed in on the particular combination of parameters that characterize the Dutch auctions of interest. As a significant departure from the traditional methods employed by applied economists and game theorists, a novel approach is taken by formulating the auctioning problem as a constrained mathematical program and applying standard nonlinear optimization techniques to solve it. In each of the basic Dutch auction model and its two extensions, interesting properties possessed by the optimal bid levels and the auctioneer's maximum expected revenue are uncovered. Numerical examples are provided to illustrate the major propositions where appropriate. The superiority of the optimal strategy recommended in this study over two commonly-used heuristic procedures for setting bid levels is also demonstrated both theoretically and empirically. Finally, economic as well as managerial implications of the findings reported in this dissertation research are discussed.

Identification of highly gifted 5- and 6-year-old children: Measures to predict academic achievement.
Access: Use of this item is restricted to the UNT Community.
Studies indicate the educational needs of highly gifted students are best met through accelerated learning. It is difficult to recognize very young children that are suited for an accelerated curriculum because younger students frequently lack school records or portfolios used to identify gifted students. This study examined the accuracy of cognitive ability and achievement tests in predicting academic achievement by the end of second grade, correlating test results and final grade averages collected from sixteen children ages five to six who entered a public school program for high-ability learners in kindergarten. A multiple regression analysis indicated the Wechsler Preschool and Primary Scale of Intelligence produced the highest mean IQ score and a strong correlation with reading achievement. The Wechsler Individual Achievement Test contributed in small part to the prediction of academic achievement. The Naglieri Nonverbal Ability Test and the Kaufman Brief Intelligence Test-Second Edition had negative correlations with final grade averages, indicating they are not predictors of academic achievement for these students.
An Analysis of Interrater Agreement Between the Motivation Assessment Scale (MAS), Questions About Behavioral Function (QABF), and Analog Assessment Outcomes
An analysis of interrater agreement across multiple respondents on anecdotal assessments was compared with experimental functional analysis outcomes for correspondence. Experiment 1 evaluated the agreement of multiple respondents on the function of problem behavior for 22 individuals across 42 target behaviors using the Motivation Assessment Scale (MAS) and the Questions About Behavioral Function (QABF). Results showed agreement on the primary maintaining consequence for 4 or 5 of the 5 respondents in 52% (22/42) of the individual's target behaviors with the MAS and 57% (24/42) with the QABF. Experiment 2 examined whether correspondence occurred between the anecdotal assessment results and experimental functional analysis (EFA) results for 7 individuals selected from Experiment 1. Correspondence between the QABF assessment and the EFA was found for 6 of 7 participants, and 4 of the 7 showed correspondence between the EFA and the MAS. This study showed that the QABF had higher correspondence with analog assessments than the MAS thus, supporting the previous findings of Paclawskyj et al. (2001).
Rail Transit and Its Influence on Land Use: A Dallas Case Study
Access: Use of this item is restricted to the UNT Community.
Mass transit investments continue to be utilized in many cities as means of dealing with various transportation issues. In Dallas Texas, light rail transit was developed with the hopes of encouraging compact and orderly growth. This research uses the DART system as a case study in examining transportation/land use relationships in Dallas. As such, this thesis reviews past research that examined transit systems impacts on urban areas, analyzes historical changes in land use pattern development around the existing twenty stations of the DART light rail starter system, and summarizes the progression of land use trends in the transit corridor as they relate to DART impacts. Results of this study suggest that DART's light rail system has been an effective tool used in achieving the transportation and land use goals for the region. Finally, recommendations are presented with respect to what can be expected for future light rail development in Dallas.
Daughters of the King and Founders of a Nation: Les Filles du Roi in New France
The late seventeenth century was a crucial era in establishing territorial claims on the North American continent. In order to strengthen France's hold on the Quebec colony, Louis XIV sent 770 women across the Atlantic at royal expense in order to populate New France. Since that time, these women known as the filles du roi, have often been reduced to a footnote in history books, or else mistakenly slandered as women of questionable morals. This work seeks to clearly identify the filles du roi through a study of their socioeconomic status, educational background, and various demographic factors, and compare the living conditions they had in France with those that awaited them in Canada. The aim of this undertaking is to better understand these pioneer women and their reasons for leaving France, as well as to identify the lasting contributions they made to French-Canadian culture and society.
Examining the Origins of Sociology: Continuities and Divergences Between Ibn Khaldun, Giambattista Vico, August Comte, Ludwig Gumplowicz, and Emile Durkheim
This thesis examines the extent to which Ibn Khaldun can legitimately be considered a founding father of sociology. To pursue this research, Khaldun's theoretical framework will be compared with four Western scholars: Auguste Comte, Emile Durkheim, Giambattista Vico, and Ludwig Gumplowicz. This paper begins with an Introduction (Chapter I), followed by a general overview of Khaldun's work (Chapter II). Next, Khaldun's work is compared to that of Auguste Comte (Chapter III), Emile Durkheim (Chapter IV), Ludwig Gumplowicz (Chapter V) and Giambattista Vico (Chapter VI). In each of these chapters, Khaldun is compared and contrasted to the other social theorist, illustrating their similarities and considering their differences. Finally, in Chapter VII, I put forth conclusions that consider the extent to which Khaldun can validly be considered a founding father of sociology.
The Legacy of Theodore Leschetizky as Seen through His Pedagogical Repertoire and Teaching Style
Access: Use of this item is restricted to the UNT Community.
Theodore Leschetizky's singular pianistic legacy survives to this day because of his revolutionary pedagogical methods and his compositions for the piano repertory. The amalgamation of these two aspects formed his distinctive contributions to the fields of piano and piano pedagogy and left an indelible mark on the history of the instrument. His students lead an impressive list of the greatest artists of the previous century, each influencing the evolution of pianism with their own remarkable style and personality. While Leschetizky was arguably without peer as a pedagogue, many pianists today are unaware of the vast number of compositions that he wrote. These pieces were intended not only for the concert stage, but also as a very specific pedagogical repertoire that he used within his own teaching studio. This repertoire comprises a vital component of the Leschetizky legacy, albeit one which is often slighted in comparison. It is imperative that the pianists of our current generation understand the dual aspects of his contribution to our art form, in order to fully grasp the way in which he has changed the face of pianism. The purpose of this dissertation and lecture recital is to enumerate the various aspects that constitute the dual components of Leschetizky's pianistic legacy. For pedagogues of the current generation, it is of vital importance that we understand not only our own personal pedagogical lineage, but the various other individuals that, through their contributions, have led us to where we are in our understanding of the instrument. What is needed in the current research on this subject is one individual source that not only documents the characteristics of a pedagogical genius, but explores the legacy he left for future generations through documented accounts of his students and the examination of his own unfamiliar, pedagogical repertoire for the piano.
A Study of Student's Perceptions of Blended Learning Environments at a State-Supported Postsecondary Institution
The purpose of this study was to conduct exploratory research regarding students' perceptions of blended learning environments at a state supported postsecondary institution. Specifically investigated were students' overall perceptions of blended learning environments, the reasons they chose to take a blended course, and whether generational differences existed in students' affected perceptions. An electronic survey was distributed to students enrolled in blended learning courses at the end of the spring 2009 term.
161 Glass: Site Specific Music in an Artistic Context
The composition 161 Glass is a 17-minute musical work with percussion, wind and brass instruments in which the intersection of mid-century architecture, and the art and culture of a dynamic city are inextricably linked. Through this paper, I explore the process of composing a musical work in relationship to the significance of site specific context. The paper begins by defining the concept of site specific art works; then reviews the discourse of the intersection of art, music and architecture. I then delve into the cultural and geographic context surrounding this project from the modern era through the present, and how those perspectives apply to the building and my piece. I reveal how the composition relates the musical ideas to the site. Finally, I describe the collaborative process between myself, the musicians and the Dallas Contemporary staff.
Retirees' Attitudes Toward Mental Illness Treatment: A Life-Course Perspective
This purpose of this dissertation was to examine the attitudes of retirees toward mental illness treatment. Secondary data from the Survey Research Center at the University of North Texas was utilized for this study. The focus was on the influence that gender, income, education, race/ethnicity, personal experience, fear, goodwill, and social control might have had on retirees' attitudes toward mental illness treatment. An n = 225 was selected out of the existing data to serve as the sample population. Binary logistic regression was utilized to analyze the data. Results indicated that the obtained significant findings were consistent with existing literature.
Determining Factors that Influence High School Principal Turnover Over a Five Year Period
The purpose of this study was to determine the effects of salary, compensation and benefits, accountability, job stress, increased instructional responsibilities, changes in student demographics, lack of support, politics, advancement opportunities and promotion on tenure and turnover among high school principals in the state of Texas. The participants in the study included 60 Texas high school principals who left a high school principalship for a different high school principalship within the past 5 years. The participants completed the Texas Principal Survey and data were analyzed using binary logistic regression. The data indicated that salary, compensation and benefits was a significant factor in predicting an increase in the odds of principal turnover for principals who had been in their prior principalship 5 or more years over principals who had been in their prior principalship less than 5 years. Additionally, advancement opportunities was a significant factor in predicting a decrease in the odds of principal turnover for principals who had been in their prior principalship 5 or more years over principals who had been in their prior principalship less than 5 years. Responses from an open ended question asking principals why they left their prior principalship suggested that principals left for reasons including new challenges, lack of support and family. The results of this study support the need for continued research in the area of principal turnover and provide insight to district superintendents, school boards and principals.
Microwave-Assisted Synthesis, Characterization, and Photophysical Properties of New Rhenium(I) Pyrazolyl-Triazine Complexes
The reaction of the chelating ligand 4-[4,6-bis(3,5-dimethyl-1H-pyrazol-1-yl)-1,3,5-triazin-2-yl]-N,N-diethyl-benzenamine, L, with pentacarbonylchlororhenium by conventional heating method produces the complexes fac-[ReL(CO)3Cl2] and fac-[Re2L(CO)6Cl2] in a period of 48 hours. The use of microwaves as the source of heat and the increase in the equivalents of one of the reactants leads to a more selective reaction and also decreases the reaction time to 1 hour. After proper purification, the photophysical properties of fac-[ReL(CO)3Cl] were analyzed. The solid-state photoluminescence analysis showed an emission band at 628 nm independent of temperature. However, in the solution studies, the emission band shifted from 550 nm in frozen media to 610 nm when the matrix became fluid. These results confirm that this complex possess a phenomenon known as rigidochromism.

This study examines the fixed media composition Phoné by John Chowning from its aesthetic perspective, compositional theory and computer sound synthesis techniques. Fast Fourier Transform analyses are used to create spectrograms. The findings from the spectrograms are juxtaposed with compositional philosophies of John Chowning, Jean-Claude Risset, Pierre Schaeffer and Arnold Schoenberg and the techniques are represented via PureData patches.
Use of GIS to Identify and Delineate Areas of Fluoride, Sulfate, Chloride, and Nitrate Levels in the Woodbine Aquifer, North Central Texas, in the 1950s, 1960s, 1970s, 1980s, and 1990s
ArcView and ArcInfo were used to identify and delineate areas contaminated by fluoride, sulfate, chloride, and nitrate in the Woodbine Aquifer. Water analysis data were obtained from the TWDB from the 1950s to 1990s covering 9 counties. 1990s land use data were obtained to determine the relationship with each contaminant. Spearman's rank correlation coefficients and Kruskal-Wallis tests were used to calculate relationships between variables. Land uses had little effect on distributions of contaminants. Sulfate and fluoride levels were most problematic in the aquifer. Depth and lithology controlled the distributions of each contaminant. Nitrate patterns were controlled mainly by land use rather than geology, but were below the maximum contaminant level. In general, contaminant concentrations have decreased since the 1950s.
Three Topics in Descriptive Set Theory
This dissertation deals with three topics in descriptive set theory. First, the order topology is a natural topology on ordinals. In Chapter 2, a complete classification of order topologies on ordinals up to Borel isomorphism is given, answering a question of Benedikt Löwe. Second, a map between separable metrizable spaces X and Y preserves complete metrizability if Y is completely metrizable whenever X is; the map is resolvable if the image of every open (closed) set in X is resolvable in Y. In Chapter 3, it is proven that resolvable maps preserve complete metrizability, generalizing results of Sierpi&#324;ski, Vainštein, and Ostrovsky. Third, an equivalence relation on a Polish space has the Laczkovich-Komjáth property if the following holds: for every sequence of analytic sets such that the limit superior along any infinite set of indices meets uncountably many equivalence classes, there is an infinite subsequence such that the intersection of these sets contains a perfect set of pairwise inequivalent elements. In Chapter 4, it is shown that every coanalytic equivalence relation has the Laczkovich-Komjáth property, extending a theorem of Balcerzak and G&#322;&#261;b.
