The efficacy of anti-predator behaviour in the wood fog tadpole (Rana sylvatica) /

Activity has been suggested as an important behaviour that is tightly linked with predator avoidance in tadpoles. In this thesis I examine predator-prey relationships using wood frog tadpoles {Rana sylvaticd) as prey and dragonfly larvae {AnaxJunius) and backswimmers {Notonecta undulatd) as predators. I explore the role of prey activity in predator attack rates, prey response to single and multiple predator introductions, and prey survivorship. The data suggest that Anax is the more successful predator, able to capture both active and inactive tadpoles. In contrast, Notonecta strike at inactive prey less frequently and are seldom successftil when they do. A mesocosm study revealed that the presence of any predator resulted in reduced activity level of tadpoles. Each predator species alone had similar effects on tadpole activity, as did the combined predator treatment. Tadpole survivorship, however, differed significantly among both predator treatments and prey populations. Tadpwles in the combined predator treatment had enhanced risk; survivorship was lower than that expected if the two predators had additive effects. Differences in survivorship among wood frog populations showed that tadpoles from a lake habitat had the lowest survivorship, those from a shallow pond habitat had an intermediate survivorship, and tadpoles from a marsh habitat had the highest survivorship. The frequency of interactions with predators in the native habitat may be driving the population differences observed. In conclusion, results from this study show that complex interactions exist between predators, prey, and the environment, with activity playing a key role in the survival of tadpoles.

Anti-Oedipus en-procés : a comparative analysis of Kristeva and Deleuze & Guattari

The present thesis is an attempt to bring into dialogue what appear to be two radically different approaches of negotiating subjectivity in late Western Modernity. Here the thought of Julia Kristeva as well as Gilles Deleuze and Felix Guattari are fully engaged. These thinkers, the latter two being considered as one, have until now remained strangers to one another. Consequently much confusion has amassed concerning their respective philosophical, as well as social/political projects. I take up the position that Deleuze and Guattari's account of subjectivity is a commendable attempt to understand a particular type of historical subject: late modern Western man. However I claim that their account comes up short insofar as I argue that they lack the theoretical language in order to fully, and successfully, make their point. Thus I argue that their system does not stand up to its own claims. On the contrary, by embracing the psychoanalytic tradition - staying rather close to the Freudian and Kleinian schools of thought - I argue that it is in fact Kristeva that is better equipped to provide an account of this particular subject. Considerable time is invested in fleshing out the notion of the Other insofar as this Other is central to the constitution of subjectivity. This Other - insofar as this Other is to be found in Kristeva's notion of the chora -- is something I claim that Deleuze and Guattari simply undervalued.

Between the panels: How anti-Black racism has recycled myths of the Black body in comic books

Anti-Black racism continues to be a widespread problem, and as such deserves investigation and elimination. As Jackson (2006) says; “There is a hyperawareness…of the negative inscriptions associated with the Black masculine body as criminal, angry and incapacitated.” (2) To continue the study of the changing face of racism, the researcher must be well equipped with a contemporary methodology which is adaptable and exploratory. Due to the malleability of racism, research into its elimination must make inroads to areas that have heretofore been neglected and overlooked by traditional academic study. This project achieves a unique perspective by undertaking a theoretical exploration of racist stereotypes and motifs in the world of mass produced superhero comic books, a genre of comics which has neither yet been thoroughly investigated for the use of racist stereotypes nor been the focus of anti-racist scholarship.

Making Queer Anti-capitalist Resistance Intelligible: Reading Queer Childhood in the Ruins of Neoliberalism

In challenging normative social relations, queer cultural studies has shied away from deploying historical materialist theoretical tools. My research addresses this gap by drawing these two literatures into conversation. I do so by investigating how global economic relations provide an allegorical and material context for the regulation, representation and re-imagining of working-class queer childhood through anti- capitalist queer readings of three films: Kes, Billy Elliot, and Boys Village. I deploy this reading practice to investigate how these films represent heteronormative capitalism’s systematic extermination of the life possibilities of working class children, how children resist forces of normalisation by creating queer times and spaces, and how nostalgia engenders a spatio-temporal understanding of queerness through a radical utopianism. My analysis foregrounds visual cultural productions as sites for understanding how contemporary social worlds exclude queer working class children, who struggle to insert themselves into and thereby shift the grounds of normative social relations.

Subjective Ambivalence and the Expression of Anti-Gay Bias

Univalent attitudes toward gay people have been widely studied, but no research to date has examined ambivalent (i.e., torn, conflicted) attitudes toward gay people. However, the Justification-Suppression Model (JSM; Crandall & Eshleman, 2003) proposes that ambivalence leads to biased expressions through intrapsychic processes which facilitate biased expression, particularly in contexts presenting strong justifications for expressing prejudice and weak pressures to suppress prejudice. I test these implications in the context of bias toward gay people. In Study 1, the measurement of ambivalence is examined in terms of both subjective ambivalence (i.e., the reported experience of “torn” attitudes) and calculated ambivalence (i.e., mathematical conflict between positive and negative attitude components). I find that higher subjective ambivalence is only associated with more negative attitudes toward gay people (and not positive attitudes toward gay people), and that higher subjective ambivalence predicts less gay rights support even after taking negative and positive attitudes toward gay people into account. Further, higher subjective ambivalence is associated with ideological opposition to gay people and more negative intergroup emotions (e.g., intergroup disgust). These findings suggest it is valuable to examine the unique component of subjective ambivalence separate from univalent negativity. Because calculated ambivalence measures are mathematically dependent upon a univalent negative measure, they cannot be examined separately from negativity. Therefore, subjective ambivalence is the focus of Study 2. The main goals of Study 2 were to determine why and when subjective ambivalence is related to bias. I examined the extent to which the negative relation between subjective ambivalence and opposition to anti-gay bullying can be accounted for by lower intergroup empathy and lower collective guilt, which may facilitate the expression of bias in keeping with the JSM. The relation between subjective ambivalence and anti-gay bullying opposition was examined within four social contexts based on a 2 (high vs. low offensiveness) x 2 (normatively unjustified vs. normatively justified) manipulation. I expected that higher subjective ambivalence would be most strongly related to lower intergroup empathy and collective guilt when there are the strongest justifications for bias expression, and that lower intergroup empathy and collective guilt would lead to less opposition to anti-gay bullying. Higher subjective ambivalence predicted less anti-gay bullying opposition. After accounting for positivity and negativity, the direct effect of subjective ambivalence was no longer significant, yet subjective ambivalence uniquely predicted intergroup empathy, which in turn predicted less anti-gay bullying opposition. These findings provide evidence that subjective ambivalence is largely negative in nature, but also presents evidence for a unique component of subjective ambivalence (separate from univalent attitudes) associated with low intergroup empathy and negativity. In contrast to previous research, I found very little evidence for the context-dependency of subjective ambivalence. Further research on subjective ambivalence, including subjective ambivalence toward other social groups, may expand our understanding of the factors leading to biased expressions.

Religious Diversity and Teacher Education: Experiences and Perspectives of Muslim Women as Teacher Candidates in Pre-service Programs

This qualitative research project explores the insights of Muslim women as teacher candidates completing pre-service programs in Ontario. Ontario schools cater to students from many ethnic, cultural and religious groups, including a sizable Muslim population. Muslims make up 4.6% of Ontario’s population with the highest concentration of Muslims in the GTA (Statistics Canada, 2011). The Muslim population in Ontario is of a significant enough number that, in a post 9/11 world, it has prompted discussion of how to integrate Muslim populations in Canada. In this research, I explore how Islamophobic sentiment is experienced in Ontario-based teacher education programs. I use Critical Race Theory (CRT) and Critical Race Feminism (CRF) to analyse and deconstruct experiences of female Muslim teacher candidates in pre-service programs. I discuss how Muslims are a racialized group that experience racism as discussed by critical race literature; however, there is a marked difference between how Muslim men and women experience gendered Islamophobia. By using in-depth research-based interviews, I explore how Muslim women perceived diversity, education, accommodations and Islamophobia in pre-service programs. This study adds to the current literature on critical race theory and anti-racist practices in education. Furthermore, this study adds to the voice of Muslim women in the discussion of diversity and inclusivity in educational institutions.

Gender and Genre in 21st Century Visions of Sherlock Holmes

Sherlock Holmes has been one of the most-adapted characters in literature since his first appearance in A Study in Scarlet in Beeton's Christmas Annual in 1887. Each new adaptation must offer innovations that bring freshness and contemporary appeal to time-worn stories and concepts or risk irrelevancy; analyzing these changes closely sheds light on shifts in societal constructs. Taking this as a starting point, this thesis examines Sherlock and Elementary from a perspective of feminism and queer theory via methods of discourse and genre analyses, with texts ranging from 1931 to the present as objects of comparison. The research illuminates constructions of masculinity as they have changed over time, particularly the movement from an orderly, stable, rational construction of hegemonic masculinity to one that is chaotic, often violent, and anti-heroic in at least some aspects while still being invested in the status quo.

"They're trying to trick us!": Making sense of anti-oppressive children's literature in the elementary school classroom

This study examines how children make sense of “anti-oppressive” children’s literature in the classroom, specifically, books that integrate and promote positive portrayals of gender non-conformity and sexual diversity. Through a feminist poststructural lens, I conducted ethnographic observations and reading groups with twenty students in a grade one/two classroom to explore how children engage with these storybooks. I further explored how the use of these books in the classroom might help to mediate and negotiate existing gendered and heteronormative beliefs and practices within educational settings. The books used in this study challenge oppressive gender and sexuality regimes within mainstream children’s literature that have traditionally served to marginalize and silence gender non-conforming and LGBTQ individuals. Responses from participants in this study aid in questioning how dominant discourses of gender and sexuality are produced and reinforced, as well as where we may find opportunities for change and reform within the elementary school classroom.
