Virginity and Representation in the Greek Novel and Early Greek Poetry
Keywords: parthenia
ancient novel

The question asked by this thesis is twofold: first, what is the relevance and purpose of the generic prominence of the motif of παρθενία in the Greek novels of the first centuries A.D., and secondly, what is the broader significance of female virginity in ancient Greek literature. In order to answer this double question, the first part of the thesis examines in detail a number of literary texts from Early Greek Literature in which the theme of παρθενία is a central concern. Thus, a close reading of Homer’s Odyssey reveals the crucial role played by παρθενία in mapping imaginary spaces such as Scheria. A close reading of Sappho sheds light on the sense of continuation that exists between a girl’s premarital stage and her wedding and marriage, which will prompt a definition of Greek marriage as “the symbolic preservation of παρθενία.” In contrast, by focusing on unsuccessful, distorted weddings and marriages, Greek tragedy nonetheless upholds the necessity of a smooth, unbroken transition between virginity and the wedded state in order that a successful marriage be possible. The chapter on Aeschylus’ Suppliants focuses on the incomprehensibility of the concept of παρθενία from a non-Greek point of view, that of the pre-Greek daughters of Danaus and their suitors. The second half of the thesis moves forward five centuries and examines the generic relevance of παρθενία in the Greek novels. Most of these novels (including fragments) are interested in this theme, which appears to be associated with the double affiliation of the novels to fictional literature (generically in verse) and referential literature (generically in prose). Moreover, these novels stress the continuity between the premarital stage and marriage, as the discordant accounts of Lycaenion and the main narrator at the end of Longus’ novel about the effect of the wedding on the παρθένος imply. The final chapters devoted to Longus, Achilles Tatius, and Heliodorus highlight the complex connections between the virginity of the female protagonist, the descriptions of nature or created objects, the interest in the text as artifact and the auctorial distancing.
Aspectual Scope and Contrast in English and Japanese
Keywords: linguistics
aspect
Japanese
syntax

This thesis presents a feature-based approach to aspect. I argue that both viewpoint aspect and lexical aspect are generated from the presence of functional properties that operate at three levels of syntactic structure: lexical, predicate, and clausal. The same aspectual feature has a different effect on the aspectual properties of the clause as a whole depending on the level at which it is active and the contrasts in which it participates. I illustrate this for English and Japanese, showing that a small number of syntactic features can capture the differences and similarities between the aspectual systems. I propose that aspect in English is determined by two functional heads: AspQ, which encodes quantity (i.e., telicity), and AspA, which encodes atomicity (i.e., punctuality). AspQ may either be a root modifier, lexically encoding quantity, or head a separate functional projection within the vP system, where it is licensed by a quantized argument. AspA may also be a root modifier, lexically encoding atomicity; it may also appear in the inflectional domain, where it encodes clausal non-atomicity (i.e., imperfective aspect). I propose that Japanese is like English in that AspA may be active at the root level; however, it differs from English in that AspA may also be active at the vP level, where it encodes the fact that the predicate is represented as a single unit. Japanese also differs from English in that it does not make use of the feature AspQ, meaning that Japanese has no quantity distinction, and makes use of the feature State, which heads a functional projection where light verbs such as iru &lsquo;be&rsquo; are merged. Thus, the differences in the aspectual systems of English and Japanese are attributed to a few features that are active at different levels of syntactic structure.
A Model of Information Sampling using Visual Occlusion
Keywords: Visual occlusion
Information Processing
Visual Sampling
Uncertainty

Three stages of research were carried out to investigate the use of the self-paced visual occlusion technique, and to model visual information sampling. Stage 1. A low-fidelity driving simulator study was carried out to investigate the effect of glance duration, a key parameter of the self-paced occlusion technique, on occlusion times. Results from this experiment, paired with analysis of data available from an on-road driving study, found an asymptotic relationship between the two variables. This finding has practical implications for establishing the appropriate glance duration in experimental studies that use self-paced visual occlusion. Stage 2. A model of visual information sampling was proposed, which incorporates elements of uncertainty development, subjective thresholds, and an awareness of past and current states of the system during occlusion. Using this modelling framework, average information sampling behaviour in occlusion studies can be analysed via mean occlusion times, and moment-by-moment responses to system output can be analysed via individual occlusion times. Analysis using the on-road driving data found that experienced drivers demonstrated a more complex and dynamic sampling strategy than inexperienced drivers. Stage 3. Findings from Stage 2 led to a simple monitoring experiment that investigated whether human operators are in fact capable of predicting system output when temporarily occluded. The platform was designed such that the dynamics of the system naturally facilitated predictions without making the monitoring task trivial. Results showed that participants were able to take predictive information into account in their sampling decisions, in addition to using the content of the information they observed from each visual sample.
Exploring Matter-wave Dynamics with a Bose-Einstein Condensate
Keywords: Bose-Einstein condensation
Optical lattices
Particle scattering
Quantum mechanics

Bose-Einstein condensates of dilute gases provide a rich and versatile platform to study both single-particle and many-body quantum phenomena. This thesis describes several experiments using a Bose-Einstein condensate of Rb-87 as a model system to study novel matter-wave effects that traditionally arise in vastly different systems, yet are difficult to access. We study the scattering of a particle from a repulsive potential barrier in the non-asymptotic regime, for which the collision dynamics are on-going. Using a Bose-Einstein condensate interacting with a sharp repulsive potential, two distinct transient scattering effects are observed: one due to the momentary deceleration of particles atop the barrier, and one due to the abrupt discontinuity in phase written on the wavepacket in position-space, akin to quantum reflection. Both effects lead to a redistribution of momenta, resulting in a rich interference pattern that may be used to reconstruct the single-particle wavefunction. In a second experiment, we study the response of a particle in a periodic potential to an applied force. By abruptly applying an external force to a Bose-Einstein condensate in a one-dimensional optical lattice, we show that the initial response of a particle in a periodic potential is in fact characterized by the bare mass, and only over timescales long compared to that of interband dynamics is the usual effective mass an appropriate description. This breakdown of the effective mass description on fast timescales is difficult to observe in traditional solid state systems due to their large bandgaps and fast timescale of interband dynamics. Both these experiments make use of the condensate's long coherence length, and the ability to shape and modulate the external potential on timescales fast compared to the particle dynamics, allowing for observation of novel matter-wave effects.
Fathers to a Fatherless Nation: From Abjection to Legacy in Spanish and Catalan Autobiographies after Franco
Keywords: Literature

Autobiography

This dissertation examines the figure of the father in autobiographies published in Spain after the death of the Spanish dictator, Francisco Franco, in 1975. It analyzes how four well-known Spanish authors born in Barcelona, Carlos Barral, Juan Goytisolo, Clara Janés, and Terenci Moix, portray the figure of the father in their memoirs. I consider first and foremost the authors’ depiction of the biological father. Nonetheless, I read this father in relation to the political figurehead of Franco, who was portrayed by many as father to the Spanish nation. The four authors either blame their fathers for being an authoritarian figure in the shadow of the dictator or present him as an absent but alternative model to the singular vision of the patriarchal household promoted by the regime. I argue that these four writers question Franco’s paternity and foster other conceptions of fatherhood in the newly democratic Spain. This dissertation addresses several interrelated questions: To what extent do real fathers collapse and step away from the ever-present figure of the Spanish dictator as a censoring father? How do father figures influence one’s own gender subjectivity and what is the relationship between fathers and the transformation of gender models during the Spanish transition to democracy? In which ways are fathers central in the construction of selfhood in autobiographical writings in general and in post-Franco Spain in particular? The close reading of these four writers illuminates the strong bonds between father figures, autobiographical writing and Oedipal narratives in the literary scene of the Spanish Transition and more broadly in the three decades following Franco’s death. Drawing from psychoanalysis, feminism and theory on autobiography, I analyze how the language, space, body, and death of the father are essential to the construction of an autobiographical self. I also contend that the reading of these authors’ melancholic state after the death of their fathers offers a new way of understanding the politics of mourning in Spain. These authors’ considerations of the figure of the father illustrate divergent attempts to deal with desired and undesired legacies of Franco’s dictatorship and, in this sense, this dissertation establishes a dialogue with current debates about memory, generational replacement, and the politics of inheritance and legacy in Spain.
Errorless Classroom Management for Students with Severe Conduct Problems: A Staff-training Approach
Keywords: Classroom Management
Conduct Problems

Proactive classroom management involves teacher use of a range of positive interaction and intervention strategies for managing student behaviour in the classroom. This approach to classroom management has been shown to positively influence student academic achievement, behaviour, and social-emotional well-being, as well as teacher job satisfaction, stress levels, and turnover rate. Unfortunately, teachers often receive minimal training in such strategies, leading them to use more reactive forms of classroom management as a means of controlling problematic student behaviour. Given that reactive procedures can have many unintended negative side effects, there is a need for in-service provision of additional teacher training in proactive approaches, especially in classrooms where student problem behaviours are rampant. The present study was designed to address this need by examining the effectiveness of Errorless Classroom Management (ECM), a proactive classroom management program that builds student tolerance to classroom challenges by teaching them four keystone skills: compliance, social skills, on-task behaviour, and communication. We provided ECM training to two staff members (one teacher and one educational assistant) who were working in a special education classroom for students demonstrating extremely high levels of severe antisocial behaviour. The goal of this in-service training program was to alter staff members’ classroom management practices in order to engender covariant improvements in student behaviour. Using time-series observations, we examined staff and student behaviour before and after ECM training. We also investigated the social validity of treatment effects through the use of staff-report questionnaires. Data revealed that staff members effectively reduced their use of reactive strategies following training but were inconsistent in their application of proactive strategies. In turn, student problem behaviour markedly declined following training; however, improvements on other student outcome measures were not consistently observed. Moreover, variability in staff members’ satisfaction ratings and stress scores suggest a modest overall level of social validity. These findings provide early support for the ECM training program as a socially acceptable form of intervention. These results also suggest that it is possible to effect change in student behaviour by training staff members in positive forms of classroom management.

Cyclic nucleotide-gated channels (CNGCs) are non-selective cation channels that were first identified in vertebrate photosensory and olfactory neurons. Although the physiological roles and biophysical properties of animal CNGCs have been well studied, much less is known about these channels in plants. The Arabidopsis genome encodes twenty putative CNGC subunits that are postulated to form channel complexes that mediate various physiological processes involving abiotic and biotic stress responses, ion homeostasis and development. The identification of Arabidopsis autoimmune CNGC mutants, such as defense no death class (dnd1 and dnd2), and the constitutive expressor of pathogenesis related genes 22 (cpr22) implicate AtCNGC2, 4, 11 and 12 in plant immunity. Here, I present a comprehensive study of the molecular mechanisms involved in CNGC-mediated signaling pathways with emphasis on pathogen defense. Previously, a forward genetics approach aimed to identify suppressor mutants of the rare gain-of-function autoimmune mutant, cpr22, identified key residues that are important for CNGC subunit interactions and channel function. First, I present a structure-function analysis of one of these suppressor mutants (S58) that revealed a key residue in the cyclic nucleotide binding domain involved in the stable regulation of CNGCs. Second, I present a new suppressor screen using AtCNGC2 T-DNA knockout mutants that specifically aimed to identify novel downstream components of CNGC-mediated pathogen defense signaling. In this screen, I successfully isolated and characterized the novel Arabidopsis mutant, repressor of defense no death 1 (rdd1), and expanded this study to demonstrate its involvement in AtCNGC2 and AtCNGC4-mediated signal transduction. Additionally, I demonstrated for the first time, the physical interaction of AtCNGC2 and AtCNGC4 subunits in planta. The findings presented in this thesis broaden our current knowledge of CNGCs in plants, and provide a new foundation for future elucidation of the structure-function relationships and signal transduction mediated by these channels.
Teachers' and Principals' Perceptions of Contexts and Conditions that Maintain Bullying in Elementary Schools

ABSTRACT Although extensive research has been conducted on bullying, few studies have explored factors that elicit, impact, and maintain the dynamics of bullying from the perspectives of teachers and principals. The purpose of this study was to understand the complex nature of bullying through exploring the ecological risk factors that allow this alarming phenomenon to flourish. The influence of factors at the microsystem, mesosystem, exosystem, and macrosystem on the dynamic interaction between the bully and the victim is explained. Another goal of this research was to capture the complexity and multidimensionality of the teacher’s role in bullying prevention and intervention. The study offers the first comprehensive analysis of the ecological and contextual variables that interact to provide fertile grounds for bullying. Detailed information about principals’ and teachers’ perceptions of bullying experiences was gathered through 8 in-depth focus groups for teachers and 10 interviews with principals. Qualitative analyses of the data led to the emergence of overarching themes and related subthemes. Bronfenbrenner’s ecological model (1979 ) was used to provide a conceptual and comprehensive framework that addressed the multifaceted variables. The finding indicated that a complex interrelation of variables was found to be central to victimization. The incidence of bullying was found to be directly influenced by individual traits as well as all the other ecological systems. Among the most salient findings was the influence of the peer ecology on bullying as a group phenomenon. The etiology of bullying as a manifestation of much deeper problems at the bully level was among the new findings. The impact of video games and television reality shows on bullying behaviour was also identified. The findings emphasized the significance of the teacher personality, positive teacher-student relationship, empathy, and training in classroom management for efficacy in addressing bullying prevention and intervention. Finally, the study offers recommendations for teacher training institutions.
Genetic Determinants of Psoriatic Arthritis
Keywords: genetic epidemiology

Psoriatic Arthritis (PsA) is an inflammatory arthritis associated with psoriasis that leads to progressive joint damage. Genetic variants in the Major Histocompatibility Complex (MHC) region on human chromosome 6p, especially Human Leucocyte Antigen (HLA), are the most important genetic risk variants associated with susceptibility to PsA. I aimed to investigate the heritability of PsA and to determine the association between HLA polymorphisms with susceptibility and severity of PsA. I first validated the new CASPAR classification criteria for PsA in patients in with both early and established disease. Subsequently, I demonstrated that PsA as defined by the CASPAR criteria has a high recurrence risk ratio. In a large case-control and family-based association study, I demonstrated that the class I HLA alleles, HLA-C*12/B*38, -B*27 and -C*06/B*57 are associated with increased susceptibility to PsA. HLA class I molecules biologically interact with Killer-cell Immunoglobulin-like Receptors (KIR) on Natural Killer (NK) to influence immune response. I demonstrated that KIR2DS2 and HLA C group 2 and HLA-B Bw4 were associated with PsA susceptibility. Further analyses of PsA cases with Type II psoriasis and with dactylitis suggested that HLA-C*02, -B*27, -B*38 and KIR2DS2 may be markers of musculoskeletal manifestations of PsA. Furthermore, using longitudinal data, I demonstrated that HLA-B*39, -B*27, -A*02 and KIR3DS1 are associated with peripheral joint damage progression whereas the alleles –DQB1*0604, -C*04 and –B*60 are associated with less damage progression. HLA-C*02, -C*12, -DQB1*0609 and KIR2DS1 are associated with higher risk of sacroiliitis, and HLA-B*27 with syndesmophytes. HLA-A*29 was associated with reduced risk of development of both sacroiliitis and syndesmophytes. These studies indicate that HLA alleles and KIR genes are important in PsA susceptibility and severity and suggest that CD8+ T cells and NK cells that modulate the innate and adaptive immune response play an important role in the susceptibility and severity of PsA.
On the Clinical Applicability and Translation of Genetic Discoveries in Schizophrenia
Keywords: copy number variation

Schizophrenia is a genetically complex neuropsychiatric disease. Myths and uncertainty about aetiology, and concerns about familial recurrence, may contribute to the significant stigma and burden on families. There has recently been concrete progress in understanding individual genetic causes of schizophrenia, which are now known to extend beyond 22q11.2 microdeletions to include other large rare copy number variations. However, there are limited data on issues germane to the translation of these genetic discoveries into clinical practice. The aim of this thesis was to evaluate the contemporary clinical applicability of genetic testing and genetic counselling in schizophrenia. First, general genetic counselling was provided to both adults with schizophrenia without individually relevant genetic test results and their family members. Pre-counselling, there was evidence of widespread misconceptions about schizophrenia aetiology and familial recurrence risks, which were associated with considerable psychological distress. Post-counselling, the myriad significant lasting benefits of genetic counselling included reductions in stigma. The results provided initial evidence of need for, and efficacy of, genetic counselling for schizophrenia. A first ever study was then conducted of the impact of providing a specific aetiological explanation for schizophrenia. Affected individuals and family members were found to value a molecular genetic diagnosis of a 22q11.2 microdeletion for its ability to explain the presence of stigmatized neuropsychiatric conditions. An investigation of transmission patterns and reproductive fitness associated with 22q11.2 microdeletions provided novel insights into the evolutionary biology and clinical correlates of this structural rearrangement. The results demonstrated the scientific and clinical benefits of identifying a genetic subtype of schizophrenia. Last, high resolution genome-wide microarrays were used to investigate rare copy number variations in a prospectively recruited community-based schizophrenia cohort. Clinically significant variants were greatly enriched in schizophrenia, even with 22q11.2 microdeletions a priori excluded. The collective prevalence of these genetic variants in a single community catchment area was high, approaching that seen in autism, where clinical microarray testing is now a first-tier diagnostic test. Collectively, the findings of these pioneering studies suggest a role for genetic testing and genetic counselling in the contemporary management of schizophrenia.
