10381 Summary and Abstracts Collection -- Robust Query Processing

Dagstuhl seminar 10381 on robust query processing (held 19.09.10 - 24.09.10) brought together a diverse set of researchers and practitioners with a broad range of expertise for the purpose of fostering discussion and collaboration regarding causes, opportunities, and solutions for achieving robust query processing. The seminar strove to build a unified view across the loosely-coupled system components responsible for the various stages of database query processing. Participants were chosen for their experience with database query processing and, where possible, their prior work in academic research or in product development towards robustness in database query processing. In order to pave the way to motivate, measure, and protect future advances in robust query processing, seminar 10381 focused on developing tests for measuring the robustness of query processing. In these proceedings, we first review the seminar topics, goals, and results, then present abstracts or notes of some of the seminar break-out sessions. We also include, as an appendix, the robust query processing reading list that was collected and distributed to participants before the seminar began, as well as summaries of a few of those papers that were contributed by some participants

Intrapersonal, interpersonal, and physical space in anorexia nervosa: a virtual reality and repertory grid study.

This document is the Accepted Manuscript version of a published work that appeared in final form in Psychiatry Research after peer review and technical editing by the publisher. To access the final edited and published work see doi: https://doi.org.10.1016/j.psychres.2017.02.060.Anorexia nervosa (AN) is an eating disorder characterized by severe body image disturbances. Recent studies from spatial cognition showed a connection between the experience of body and of space. The objectives of this study were to explore the meanings that characterize AN experience and to deepen the examination of spatiality in relational terms, through the study of how the patient construes herself and her interpersonal world. More specifically this study aimed (1) to verify whether spatial variables and aspects of construing differentiate patients with AN and healthy controls (HCs) and are related to severity of anorexic symptomatology; (2) to explore correlations between impairments in spatial abilities and interpersonal construing. A sample of 12 AN patients and 12 HCs participated in the study. The Eating Disorder Inventory, a virtual reality-based procedure, traditional measures of spatial abilities, and repertory grids were administered. The AN group compared to HCs showed significant impairments in spatial abilities, more unidimensional construing, and more extreme construing of the present self and of the self as seen by others. All these dimensions correlated with the severity of symptomatology. Extreme ways of construing characterized individuals with AN and might represent the interpersonal aspect of impairment in spatial reference frames.Peer reviewedFinal Accepted Versio

Post(al) Apocalypse: A Letter About Virginia Woolf\u27s Fictional Letters

I set out to write about eating distress in Virginia Woolf. I wanted to write about mothers, too, in her fiction and essays, because, as Chris Kraus puts it, “Mother is Food.” I began by investigating one of Woolf’s fictional letters, written in Jacob’s Room. There, the letter arrives at breakfast. This coincidence followed me into my other readings on mothering and food, so I decided to discuss Woolf’s fictional epistolary form for an entire chapter. And then, after winter break, an entire chapter became an entire thesis

How do women with a history of SEED-AN experience navigating their lives away from and beyond their illness - A narrative inquiry study

The purpose of this study was to explore through narrative inquiry methodology the experiences of four participants as they navigated their lives away from severe and enduring anorexia nervosa (SEED-AN, Robinson, 2009). Whilst positions of what recovery can mean emerged its aim was to open up the ‘how’; how may a person journey away from a life dominated by anorexia nervosa? These first-person narratives stretched across early developmental disturbances to being caught between dread of the past, repetition in the future and their experiences in the present time. This study emerged from my own long experience of anorexia, my professional relationship within my private practice and as co-founder of Anorexic Aid, now B-eat, a UK national charity for eating disorders. This insider-researcher perspective provided what I believe to be a unique subjective and reflective dimension to this study. To analyse and frame the narratives in a way that enabled the reader to travel alongside the participants’ journey Bettelheim’s (1976) framework used to analyse fairy-tales was adapted and became a scaffold to begin the analysis. A cross-case analysis followed with Connelly & Clandinin’s (1990) three-stage narrative inquiry analytic tool adapted for this purpose. From scrutinising the transcripts in this way what began to emerge was a sense whereby relationships for all the participants were viewed as unsafe and unreliable and their sense of self shifted between invisible and invincible. There followed two distinct stages the first I refer to as ‘transition’ whereby from consistent, containing relationships new relational configurations displayed a shift from concrete ‘knowing’ to experiencing the idea of possibilities in the future. They also began to develop a capacity, to be reflective and reflexive. The second stage I have named ‘Integration’, where the narratives demonstrated a more grounded sense of ‘self and other’, of relinquishing the need to be special, of taking in the idea of being ‘ordinary’ and good enough. This study has provided a depth of understanding of SEED that appears to be little attended to in current research, the confusion of what are ‘normal and socially acceptable’ thoughts, feelings and actions and what may be eating disorder residues particularly around food, body shape and exercise. This study has further highlighted organisational challenges for the provision of therapy within the public sector which remains time-limited and focused on symptom alleviation; it conveys the importance of therapeutic consistency. A further outcome from this study that is relevant to all our clients who have experienced a long history of struggling with mental health has been to shine a torch on the importance of hope and encouragement in the therapeutic endeavour. It expands the importance of mentalisation and provides an additional concept of understanding ‘relapse’ as a positive experience, one not to be viewed negatively but rather a flag towards unprocessed material. To summarise this study has identified the primacy of emotional nourishment achieved with and through human relatedness

Robust Query Optimization Methods With Respect to Estimation Errors: A Survey

International audienceThe quality of a query execution plan chosen by a Cost-Based Optimizer (CBO) depends greatly on the estimation accuracy of input parameter values. Many research results have been produced on improving the estimation accuracy, but they do not work for every situation. Therefore, "robust query optimization" was introduced, in an effort to minimize the sub-optimality risk by accepting the fact that estimates could be inaccurate. In this survey, we aim to provide an overview of robust query optimization methods by classifying them into different categories, explaining the essential ideas, listing their advantages and limitations, and comparing them with multiple criteria

A grounded theory analysis of the forms of support on two online anorexia forums

Using Grounded theory this thesis analyses the forms of support that are present on two online anorexia forums. Data was collected through non-participant observation and online interviews with members of two online anorexia forums, one pro-anorexic in orientation, one pro-recovery. Despite the clear differences that exist between the two communities, continuities are strongly apparent, especially when looking at these forums as support environments. This thesis illustrates that support is conditional, that is takes on a variety of forms in any one environment and highlights the role of offline discourses in shaping online support. It also provides an in-depth comparison of two online anorexia forums

A Queer Politics of Imperceptibility: A Philosophy of Resistance to Contemporary Sexual Surveillance

This thesis journeys through a series of events to develop a concept of “imperceptibility” as a mode of resistance to contemporary sexual surveillance. The events I examine include biometric recognition of gender and race at airport security checkpoints, the heteropatriarchal colonial surveillance of Indigenous peoples at Standing Rock, various protest actions, and the political potentials of glitch art. Exploring their unexpected points of connection, my goal is to bring into view acts of resistance against sexual surveillance that already operate below and above the threshold of everyday perception. The project advocates for a philosophy of resistance that underscores the political importance of creating new modes of existence. Rather than engaging in the problematic of devising a new model of subjectivity, I argue that what is needed to escape from contemporary systems of capture and control is to turn from the Self as the primary site of concern and affirm instead the potentials of becoming-imperceptible. Imperceptibility signals not invisibility, but the act of relinquishing identity in favour of moving toward becoming everybody/everything. Far from a homogenizing or unitary endeavour, I propose imperceptibility as a radical celebration of difference that surges a revolutionary desire for social transformation through interconnectedness. Activating Gilles Deleuze and Félix Guattari’s pragmatic philosophy and style of writing, which emphasize multiple relations over binary oppositions, I introduce “a queer politics of imperceptibility” as a conceptual framework that takes a both/and approach to consider resistance. That is, I work with and between the tensions of feminist theories of recognition and Deleuze and Guattari’s nonrepresentational philosophy. I develop this framework in each chapter by mapping a constellation of interacting forces and affective intensities between bodies, both human and non-human. A Queer Politics of Imperceptibility makes an important intervention into the fields of feminist surveillance studies, posthumanism, affect theory, postcolonial theory and queer theory by revealing the ways in which imperceptible relations of resistance cascade into the political to generate new potentials to act in the world
