Research on the stability of attachment representations across the lifespan has led to two alternative perspectives: the prototype and revisionist perspectives (Fraley, 2002). The prototype perspective posits that there is a stable factor underlying fluctuations in representations and the revisionist perspective argues that there is no inherently stable factor. The current study employed a latent trait-state model to investigate these alternative models of stability and change in representations of romantic relationships in adolescence and young adulthood. The study also sought to identify individual characteristics and relationship experiences that are associated with changes in representations. In a sample of 200 participants, representations were assessed by interview and self-report over seven measurement occasions between ages 15 and 23. Results were consistent with the prototype perspective emphasizing that a stable, latent factor exerts a consistent influence over the lifespan. In addition to a stable component, representations incorporated a component that varies over time. Findings showed that this fluctuating component of representations was associated with internalizing and externalizing symptomatology as well as experiences of support and negative interaction in relationships.

The Vernacular Discourse of the "Arab Spring" is a project that bridges the divide between the East and the West by offering new readings to Arab subjectivities. Through an analysis of the "Arab Spring" through the lens of vernacular discourse, it challenges the Euro-Americo-centric legacies of Orientalism in Western academia and the new wave of extremism in the Arab world by offering alternative representations of Arab bodies and subjectivities. To offer this new reading of the "Arab Spring," it explores the foundations of critical rhetoric as a theory and a practice and argues for a turn towards a critical vernacular discourse. The turn towards critical vernacular discourse is important as it urges the analyses of different artifacts produced by marginalized groups in order to understand their perspectives that have largely been foreclosed in traditional cultural studies research. Building on embodied/performative critical rhetoric, the vernacular discourses of the Arab revolutionary body examines other forms of knowledge productions that are not merely textual; more specifically, through data gathered in the Lhbib Bourguiba, Tunisia. This analysis of the political revolutionary body unveils the complexity underlining the discussion around issues of identity, agency and representation in the Middle East and North Africa, and calls for a critical study towards these issues in the region beyond the binary approach that has been practiced and applied by academics and media analysts. Hence, by analyzing vernacular discourse, this research locates a method of examining and theorizing the dialectic between agency, citizenry, and subjectivity through the study of how power structure is recreated and challenged through the use of the vernacular in revolutionary movements, as well as how marginalized groups construct their own subjectivities through the use of vernacular discourse. Therefore, highlighting the political prominence of evaluating the Arab Spring as a vernacular discourse is important in creating new ways of understanding communication in postcolonial/neocolonial settings.

Despite the vast research examining the evolution of Caribbean education systems, little is chronologically tied to the postcolonial theoretical perspectives of specific island-state systems, such as the Jamaican education system and its relationship with the underground shadow education system. This dissertation study sought to address the gaps in the literature by critically positioning postcolonial theories in education to examine the macro- and micro-level impacts of extra lessons on secondary education in Jamaica. The following postcolonial theoretical (PCT) tenets in education were contextualized from a review of the literature: (a) PCT in education uses colonial discourse analysis to critically deconstruct and decolonize imperialistic and colonial representations of knowledge throughout history; (b) PCT in education uses an anti-colonial discursive framework to re-position indigenous knowledge in schools, colleges, and universities to challenge hegemonic knowledge; (c) PCT in education involves the "unlearning" of dominant, normative ideologies, the use of self-reflexivity, and deconstruction; and (d) PCT in education calls for critical pedagogical approaches that reject the banking concept of education and introduces inclusive pedagogy to facilitate "the passage from naïve to critical transitivity" (Freire, 1973, p. 32). Specifically, using a transformative mixed-methods design, grounded and informed by a postcolonial theoretical lens, I quantitatively uncovered and then qualitatively highlighted how if at all extra lessons can improve educational outcomes for students at the secondary level in Jamaica. Accordingly, the quantitative data was used to test the hypotheses that the practice of extra lessons in schools is related to student academic achievement and the practice of critical-inclusive pedagogy in extra lessons is related to academic achievement. The two-level hierarchical linear model analysis revealed that hours spent in extra lessons, average household monthly income, and critical-inclusive pedagogical tents were the best predictors for academic achievement. Alternatively, the holistic multi-case study explored how extra-lessons produces increased academic achievement. The data revealed new ways of knowledge construction and critical pedagogical approaches to galvanize systemic change in secondary education. Furthermore, the data showed that extra lessons can improve educational outcomes for students at the secondary level if the conditions for learning are met. This study sets the stage for new forms of knowledge construction and implications for policy change.

As a relatively unknown author, Mary Davys (1674-1732) has garnered scant scholarly attention and little admiration for her work. Those who have written on Davys’s prose fiction most often mention the last three texts she published, Familiar Letters betwixt a Gentleman and a Lady (1716), The Reform’d Coquet (1724), and The Accomplish’d Rake (1727), yet rare mention is made of her first three novels. Moreover, of her later novels, many scholars read them as socially conservative and as representations of Davys’s support of and belief in patriarchy. My project disproves the long-standing and generally agreed upon conceptions regarding Davys’s writings and demonstrates the significance of her life’s work to studies of the novel. By investigating contemporary cultural issues, discussing the popular genres and modes of early eighteenth-century England, and comparing and contrasting Davys’s fiction to other authors’, I explore the myriad ways in which Davys experimented with the formal properties of the novel. Also, by closely examining each novel independently, I foreground Davys’s willingness to engage with charged contemporary topics such as rape, suicide, the laws surrounding inheritance, and male privilege. Not only does she engage with these topics; there is a discernable voice of protest imbedded in the narratives. At times, the techniques Davys employed and the plots she created in her work obscured her social concerns, yet with close reading, subversion also surfaces as one of Davys’s methods. An analysis of Davys’s experimentations with prose fiction and form illuminates the ways in which those innovations allowed Davys to criticize the culture in which she lived. Furthermore, an investigation of the whole of Davys’s work and the totality of her novels—looking at both form and content—exemplifies the importance of Davys for students of feminist thought and the development of the novel.

La Malinche’s serene face and beautifully dressed figure dominates the first half of the lost sixteenth century manuscript El Lienzo de Tlaxcala, which exists today in the form of a copy made after the original. In this paper I propose an expanded study of these twenty-one representations of La Malinche as they offer insight into the Tlaxcalan’s reverence, respect, and spiritual belief in La Malinche. The Tlaxcalan leaders recognized her influence on both the Spanish and indigenous leaders during the conquest and cleverly designed a painted narrative to reinforce their connection with La Malinche to enhance their position with the Spanish. Through a multi layered study that consists of a detailed account of her biography in contrast to gender roles in Pre-Hispanic America, as well as formal and iconographic analysis of rarely examined images from the Lienzo de Tlaxcala that link La Malinche to the Virgin Mary, and a review of the ethnographic research on religious beliefs among contemporary Tlaxcalans, I will demonstrate that the mutable history of this woman made her the ideal supernatural protagonist for the people of Tlaxcala.

he dragon tree, a peculiar species native to Socotra, southwest Arabia, east Africa, Morocco, Macaronesia, and the Canary islands, possesses an intriguing iconographic history. The first wave of images date from 1470 to 1550, beginning with Martin Schongauer’s 1470 engraving of The Flight into Egypt. These depictions portray the dragon tree in the context of a handful of biblical themes and with apparent symbolic import. After 1550, religious images of the dragon tree vanish abruptly and are replaced by representations of an empirical nature. Dragon tree iconography is notable for the extent to which it did and did not leave an impression on European art. In this paper I examine the inability of dragon tree images to gain the momentum required to propel them into European iconography more permanently, and the forces that may account for the abrupt change from biblical to botanical renderings.
