This ethnographic case study investigates the diverse means and processes by which environmental identities were produced by five first grade students as they participated in an emergent, public school garden space. The children's histories, choices, personal and social experiences, expressions, and corresponding narratives are explored alongside the garden structure and social context to unpack the individualized and layered nature of children's environmental identity and care development. To locate and analyze children's engagements in the garden space, ethnographic, discourse, and narrative analysis methods are employed. The figured world concept is used to theorize and study the caring, environmental identities taken up and enacted by the children in this context. Through participation in emergent provocations, the creation and leveraging of garden artifacts, and investments in caring relationships, the children in this study shaped and cared for the garden space while it simultaneously shaped and cared for them. The environmental identity stories presented in this work broaden the definition of environmental identity to be more inclusive and less normalizing, thus, creating new spaces and moments for children to identify as environmentalists. The stories also raise implications for environmental education researchers to utilize more rigorous frameworks for investigating environmental care and identity development in the field. Findings from this research indicate that emergent garden spaces are potential sites for children to build relationships with nature in the public school. This is a significant practice for schools, as children today lack spaces in which to form environmental identities that implicate environmental care behaviors. / Ph. D.

The current dissertation investigated sexual assault victimization in virtual worlds – environments, where individuals engage through avatars, offering a deep level of immersion and interactivity. As the usage of these virtual spaces grows, so does the concern for negative experiences that mirror the sexual assault encountered in the physical world. Despite this, there is a notable gap in the quantitative analysis of virtual sexual assault (VSA) victimization. This research aimed to fill this void by exploring the prevalence of VSA victimization over the previous year and identifying potential predictors of VSA victimization through the lens of cyberlifestyle-routine activity theory. To achieve this, the current research recruited 829 English-speaking adult participants, who used/have used virtual worlds via Mechanical Turk (MTurk) using CloudResearch, which uses the sample population within MTurk but produces better-quality data. The study found that 46.44% of participants reported at least one instance of VSA victimization. VSA behaviors were categorized into unwanted sexual advances, image-based sexual abuse, and non-consensual sexual avatar manipulation. Unwanted sexual advances were reported by 35.71% of participants, image-based sexual abuse by 33.29%, and non-consensual sexual avatar manipulation by 27.99%. Applying CLRAT, the study found that higher levels of online exposure, online proximity, online deviant lifestyle, and lower levels of online guardianship were correlated with increased VSA victimization. However, the study noted that traditional guardianship concepts needed refinement for virtual environments, as mere vigilance without active intervention was insufficient to prevent victimization. Limitations, suggestions for future studies, and implications are provided based on these findings.

In this thesis I will test Yagisawa´s Extended Modal Theory of modality against two issues: the problem of accidental intrinsic properties and the problem of transworld identification. Both are part of the recurring criticism of theories supporting transworld individuals, such as the Extended Modal Theory. The first is based on Lewis criticism that argues that if a theory claims that individuals exist in more than one possible world, then transworld individuals do not possess intrinsic properties, only external ones. The second follows the rational of Quine, that argues that because anything can become anything by follow a chain of possible worlds, it becomes problematic in some cases to “discover” the modal stage of a transworld individual in another possible world. The discussion concludes that despite of the criticism above, Yagisawa provides convincing arguments to support transworld identity and EMR does a better job than the Counterpart theory in explaning modality.

This study investigates how the members of four different role-playing communities on the online platform Second Life perform social as well as dramatic roles within their community. The trajectories of power influencing these roles are my main focus. Theoretically I am relying primarily on performance studies scholar Richard Schechner, sociologist Erving Goffman, and post-structuralists Michel Foucault, Gilles Deleuze and Felìx Guattari. My methodological stance has its origin primarily within literature studies using text analysis as my preferred method, but I also draw on the (cyber)ethnographical works of primarily T.L. Taylor, Celia Pearce, and Mikael Jakobsson. In this dissertation my focus is the relationship of the role-player to their chosen role especially in terms of the boundary between being in character, and as such removed from ”reality,” and the popping out of character, which instead highlights the negotiations of the social, sometimes make-belief, roles. Destabilising and problematising the dichotomy between the notion of the online as virtual and the offline as real, as well as the idea that everything is ”real” regardless of context, my aim is to understand role-play in a digital realm in a new way, in which two modes of performance, dramatic and social, take place in a digital context online — or inworld as many SL residents call it.

Neste trabalho foi realizado um estudo sobre o uso e influências do efeito small world, ou seis graus de separação, no roteamento de redes de sensores sem fio (RSSFs). Para esse objetivo, foram analisadas as características das RSSFs que influenciam no roteamento e os diferentes tipos de protocolos. Além disso, foram estudadas as características do efeito small world e suas propriedades, de um modo geral, em redes de larga escala e com alta densidade de nós, incluindo o modelo de small world para o estudo de redes ad hoc. Realizou-se um breve estudo sobre redes overlay, redes lógicas criadas sobre a rede física com o propósito de melhorar suas qualidades e seu desempenho. A conclusão neste trabalho é que small worlds pode ser empregado para melhorar o funcionamento de protocolos de roteamento em RSSFs. / In this work, has made an study about the use and influences of the small world effect, or six degrees of separation, in routing of wireless sensors network (WSNs).

Lewisian Genuine Realism (GR) about possible worlds is often deemed unable to accommodate impossible worlds and reap the benefits that these bestow to rival theories. This thesis explores two alternative extensions of GR into the terrain of impossible worlds. It is divided in six chapters. Chapter I outlines Lewis’ theory, the motivations for impossible worlds, and the central problem that such worlds present for GR: How can GR even understand the notion of an impossible world, given Lewis’ reductive theoretical framework? Since the desideratum is to incorporate impossible worlds into GR without compromising Lewis’ reductive analysis of modality, Chapter II defends that analysis against (old and new) objections. The rest of the thesis is devoted to incorporating impossible worlds into GR. Chapter III explores GR-friendly impossible worlds in the form of set-theoretic constructions out of genuine possibilia. Then, Chapters IV-VI venture into concrete impossible worlds. Chapter IV addresses Lewis’ objection against such worlds, to the effect that contradictions true at impossible worlds amount to true contradictions tout court. I argue that even if so, the relevant contradictions are only ever about the non-actual, and that Lewis’ argument relies on a premise that cannot be nonquestion- beggingly upheld in the face of genuine impossible worlds in any case. Chapter V proposes that Lewis’ reductive analysis can be preserved, even in the face of genuine impossibilia, if we differentiate the impossible from the possible by means of accessibility relations, understood non-modally in terms of similarity. Finally, Chapter VI counters objections to the effect that there are certain impossibilities, formulated in Lewis’ theoretical language, which genuine impossibilia should, but cannot, represent. I conclude that Genuine Realism is still very much in the running when the discussion turns to impossible worlds.

This thesis starts from the observation that, while it is common for commentators to divide postmodern fiction into two general fields – one experimental and anti-mimetic, the other cautiously mimetic, there remains a fairly significant field of postmodern texts that use largely mimetic approaches but represent worlds that are categorically distinct from actuality. This third group is even more pronounced if popular culture and “commercial” fiction, in particular sf and fantasy, are taken into account. Additionally, the third category has the interesting characteristic that the texts within this group very often generate unusual loyalty among its fans. Based on a renewed investigation of the main genre critics in postmodern fiction, the first chapter suggests a tripartite division of postmodern fiction, into formalist, metamimetic, and transreferetial texts. These are provisionally circumscribed by their reference worlds: formalist fiction attempts to derail its own capacity for presenting a world; metamimetic fiction presents mediated versions of worlds closely reminiscent of actuality; and transreferential fiction sets its narrative in worlds that are experienced as such, but are clearly distinct from actuality. If transreferential fiction deals with alternate worlds, it also very often relies on the reader’s immersion in the fictional world to provide unique, often subversive, fictional experiences. This process can be identified as the exploration of the fictional world, and it is very often guided so as to be experienced as a virtual reality of sorts. If transreferential texts are experienced as interactive in this sense, it is likely that they convey experiences and insights in ways different from either of the other two strands of postmodern fiction. In order to investigate the interactive experience provided by these texts, an extended conceptual and analytical set is proposed, rooted primarily in Ricoeurian hermeutics and possible-worlds theory. These two main theoretical approaches approximately correspond to the temporal and the spatial dimensions of texts, respectively. Much of the power of these texts rooted in the care they take to guide the reader through their fictional worlds and the experiences offered by the narrative, often at the hand of fictioninternal ‘guides’. These theoretical approaches are supplement by sf theoretical research and by Aleid Fokkema’s study of postmodern character. Chapters 3, 4, and 5 apply the theoretical toolset to three paradigmatic transreferential texts: sf New Wave author M John Harrison’s Viriconium sequence; Gibson’s Sprawl trilogy; and Jeff Noon’s Vurt and Pollen, texts that have much in common with cyberpunk but which make much more extensive use of formalist techniques. Each chapter has a slightly different main focus, matching the text in question, respectively: aesthetic parameters and worldcreation strategies of transreferential fiction; close “guidance” of the reader and extrapolation; and virtual reality and identity games. The final chapter presents the findings from the research conducted in the initial study. The findings stem from the central insight that transreferential texts deploy a powerful suit of mimetic strategies to maximise immersion, but simultaneously introduce a variety of interactive strategies. Transreferential fiction balances immersion against interactivity, often by selectively maximising the mimesis of some elements while allowing others to be presented through formalist strategies, which requires a reading mode that is simultaneously immersive and open to challenging propositions. A significant implication of this for critical studies – both literary and sf – is that the Barthesian formalist reading model is insufficient to deal with transreferential texts. Rather, texts like these demand a layered reading approach which facilitates immersion on a first reading and supplements it critically on a second. The final chapter further considers how widely and in what forms the themes and strategies found in the preceding chapters recur in other texts from the proposed transreferential supergenre, including sf, magic realist and limitpostmodernist texts. / Thesis (PhD (English))--North-West University, Potchefstroom Campus, 2013.

The growing accessibility of quantum mechanics and chaos theory over the past eighty years has opened a new mode of world-creating for dramatists. An increasingly large collection of plays organize their fictional worlds around such scientific concepts as quantum uncertainty and chaotic determinism. This trend is especially noticeable within dramatic texts that emphasize a fictional, not material or metafictional, engagement. These plays construct fictional worlds that reflect the increasingly strange actual world. The dominant theoretical approaches to fictional worlds unfairly treat these plays as primarily metafictional texts, when these texts construct fictional experiences to speculate about everyday ramifications of living in a post-quantum mechanics world. This thesis argues that these texts are best understood as examples of speculative fiction drama, and they speculate about the changes to our understanding of reality implied by contemporary scientific discoveries. Looking at three plays as exemplary case studies—John Mighton’s Possible Worlds (1990), Tom Stoppard’s Arcadia (1993), and Tony Kushner’s Homebody/Kabul (2001)—this thesis demonstrates that speculative fiction theories can be adapted into fictional worlds analysis, allowing us to analyze these plays as fiction-making texts that offer nonclassical aesthetic experiences. In doing so, this thesis contributes to speculative fiction studies, fictional worlds studies, and the dynamic interdisciplinary dialogue between aesthetic and scientific discourses.
