Over one million high school students drop out of school each year in this country. Dropping out of school is a serious problem for the student, community, and the nation. Often dropouts are unable to compete in an increasingly technological society and face numerous consequences from their decision to leave school early including higher levels of poverty, unemployment, public assistance, incarceration, and poor health. Dropping out is a gradual process of school disengagement and related to individual, family, and school factors. In the past, it has been difficult to track individual student's progress through school and to determine accurate dropout and graduation rates. In 2005, the National Governors Association made a commitment to implement a uniform method to calculate and report graduates and dropouts as well as better data collections systems.This study intended to replicate aspects of other major studies around the county to determine the best early predictors of dropping out of school in this large school district in southern Arizona and use this information to build an early warning system. Student data were obtained from the district's Research and Accountability office for a cohort of students (n=6751) who began the ninth grade in fall 2006 and graduated or should have graduated in 2010. Data collected included general demographic information, academic data, number of schools attended, and school withdrawal codes.The intent of this research was to determine if there were statistically significant differences between dropouts and graduates in the variables collected and which variables yielded the highest effect sizes and should be included in the district's early warning system.Two analyses were used to determine significance differences between dropouts and graduates. Then four analyses were performed to determine the highest-yield variables for this district. Consistent with recent research in the field, the variables of ninth grade attendance, ninth grade English and Math grades, and GPA were the strongest predictors of student dropouts.Local educators can use this early warning information to help identify potential high school dropouts as early as possible and intervene more efficiently and effectively with these students.

Through an exploration of Toronto-based artist Allyson Mitchell’s craft-art, this thesis investigates the complexities surrounding the functions and roles of public and private spaces; particularly the home and the fine art museum within Canadian society. I propose a reading of Mitchell’s art practice, activism, scholarship, and curatorial activities that focuses on a queering of both private domestic space and public social space through a conflation of the two. Mitchell’s textile installations make intimate and cozy the otherwise impersonal space of the public art museum, while Mitchell queers the heteronormative space of the family home by turning it into a public art institution, an archive and a classroom. Mitchell’s bright textile enclosures, "Hungry Purse: The Vagina Dentata in Late Capitalism" and "Menstrual Hut, Sweet Menstrual Hut," for example, visibly disrupt the sanitized and impersonal space of the art museum, disrupting the dominant ideological framework that privileges normative assumptions of sexuality and sexual identity, and exclusionary hierarchies of class, able-bodiedness and access. While Mitchell’s theatrical textile installation, "Ladies Sasquatch," has predominantly been theorized as a queer critique of the myths of femininity, gender, sexuality, and the detrimental treatment of the female body within popular media; I present a reading of "Ladies Sasquatch" as a radical decolonizing spectacle that has the potential to interrupt larger nationalistic and colonial narratives reproduced by museums. Through these powerful interventions in public and private space, I suggest that Mitchell’s crafty installations offer playful acts of resistance that create counter narratives which function to decolonize our physical, psychic and emotional space, while also creating new imaginings that undermine the status quo. / Thesis (Master, Art History) -- Queen's University, 2013-01-14 15:58:08.015

MRI-guided percutaneous needle-based surgery has become part of routine clinical practice. There are millions of these procedures performed in Canada. The conventional MRI-guided needle intervention is usually performed with the primary goal of navigating a needle to a target while sparing healthy and/or critical structures. Potential limitations of conventional unassisted free-hand needle placement include the physician's ability to align and maintain the correct trajectory and angle toward a target, especially in case of deep targets. In contemporary practice, images are displayed on the operator's 2D console only outside the treatment room, where the physician plans the intervention. Then the physician enters the room, mentally registers the images with the anatomy of the actual patient, and uses hand-eye coordination to execute the planned intervention. Previous concept has been shown and preliminary results discussed from demonstrated MRI-guided needle intervention using an augmented reality 2D image overlay system in a closed configuration 1.5T MRI scanner. However, the limited availability of interventional MR imaging systems and the length of time of MR-guided interventions have been limiting factors in the past. This dissertation addresses topics related to evaluating and developing the 2D augmented reality system, the assistance device for MRI-guided needle interventions. This research effort has primarily focused on developing a new adjustable 2D MR image overlay system and validating the previous 2D image overlay system in the clinical environment. The adjustable system requirement is to overcome the oblique insertions, difficulties inherent to MR-guided procedures, and to promise safe and reliable needle placement inside closed high-field MRI scanners. This thesis describes development of the image overlay system including requirements, mechanism design and evaluation of MR compatibility. Additionally, a standalone realization of an MR image overlay system, named “The Perk Station” was developed, implemented and evaluated. The system was deployed in the laboratory as a training/teaching tool with non-bio-hazardous specimens. This laboratory version of the system allows for evaluation of trial interventions. The system also supports recording of the complete intervention trajectory for operator performance, technical efficacy, and accuracy studies of insertion techniques. / Thesis (Ph.D, Mechanical and Materials Engineering) -- Queen's University, 2013-09-30 22:21:51.469

Bullying is a serious problem for many adolescents, and one that can have detrimental effects on normal developmental processes, as chronic and severe bullying can obstruct the fulfilment of essential psychological needs. However, there are currently few targeted interventions available for chronic and severe bullying cases. The purpose of this study was to evaluate the effectiveness of the Red Balloon Learner Centres (RBLC) which are a full time personal and academic recovery programme for bullied adolescents. A mixed-methodology was utilised, and quantitative outcome measures included: depression, anxiety and trauma symptoms, self-esteem and academic engagement and self-concept. The study was non equivalent groups design (NEGD) and incorporated a comparison group of bullied adolescents from Hertfordshire local authority (LA). The aim was to compare the recovery process between groups over time by taking an initial baseline measure, and conducting follow-up assessments every three months. Both groups demonstrated significant improvements in outcome variables over time, but there were no significant differences between groups at six month follow-up on any outcome variable. Both groups reported similar recovery themes that related to need fulfilment in the areas of safety and security, control, belonging and self-esteem. Recovery is not just the absence of internalising symptomology, but constructive fulfilment of needs. Social needs were felt to be most affected by chronic and severe bullying and most difficult to fulfil constructively. It is recommended that interventions for chronically and severely bullied adolescents should enable constructive need fulfilment, which may involve changes to the ethos and culture of schools, collaborative therapeutic intervention and targeted skill building.

Childhood behavioural disorders affect up to 9% of UK children under the age of ten (Meltzer et al.,2000). The consequences of these difficulties are widespread, placing the dchild at greater risk for later psychopathology, unemployment, relatioship problems and criminal activity. The trajectory towards the development of behavioural difficulties presents a complex milieu of potential risk and protective factors. Individual risk factors includes cognitive deficits, premature birth and childhood physical illness, although these are tempered by interactions with environmental risk factors such as low socioeconomic status and parental factors such as parental self-efficacy and mental health. Parenting skills are consistently highlighted as a key factor for the mediation of behavioral difficulties, and consequently lend themselves to the most influential intervention approach - the group parenting programme. Despite a wealth of programmes available, strenth of content and supporting evidence base vary widely. Current approaches are outlined and critiqued. 'Getting throught the day' is a manualised group parenting programme developed to impact upon child behaviour, parental self-efficacy and parental wellbeing. The aim of the current study was to evaluate this resource in the community setting within which it is delivered. Following longitudinal design, group participants and parents of 'healthy controls' from local schools and nurseries completed the standarised assessment questionnaires Strenght and Difficulties Questionnaire (corroborated by teacher version), Parenting Stress Index-Short Form, Hospital Anxiety and Depression Scale and the non-standardised Tool to Measure Parenting Self-Efficacy. statistical analyses of Analysis of Variance and Analysis of Covariance were conducted as appropriate, Results indicate positive change for intervention group participants as compared to healthy controls across domains of parent self-efficacy and parent mental health. Results and clinical implications are discussed in the context of this valuable resource and the existing evidence base for group parenting interventions.

The overall aim of the thesis is to explore and analyse graffiti in a translocal context, by asking questions about the actors' view on activity, meaning and interaction. The study has been located to a physical place, Jönköping, where actors with different interest perform graffiti-related activity. The study is based on qualitative data where participant observation and interviews form the two main methods. The study also utilizes other materials, such as newspaper articles and municipal documents. Central for the theoretical orientation is that empirical data has been collected that is first-hand information on how the actors themselves find meaning in graffiti. This implies a constructivist perspective on knowledge where meaning shifts depending on whose perspective is analysed. Theoretically, the study also is linked to Becker and his arguments that research in deviance must take notice of the interaction between actors who are perceived to deviate and those actors who respond to the deviant group. The actors consist of two main groups; graffiti writers and interveners. Graffiti writers mainly consist of young men who describe themselves as belonging to a global graffiti culture. The word “interveners” has bee selected as a generic name for actors who are involved in graffiti issues due to professional duties. Similar to the graffiti writers' interveners find the meaning in graffiti by actively select information from an “outside”, which corresponds with their professional commitment. The analysis links different approaches to perspectives of combating crime, confirming art and caring for the young men's socialisation. From those different understandings, three parallel patterns of interaction are observed. Interaction developed around graffiti as a crime has elements of a battle situation. From the graffiti writers' perspective, this fight is important when designing the local scene as an integral part of a global graffiti context. At the same time there are disadvantages managing an enemy. On a personal level, individual graffiti writers have to make an estimate how graffiti writing will affect life in the long term. Interaction developed around graffiti as an art form unites graffiti writers and interveners in an ideological consensus where graffiti can be seen as an art form that adds creative qualities to urban space. One significant difference is that the graffiti writers find the local arena as an important place. This local orientation is not necessary when actors from a cultural sector put attention on graffiti. Youth workers way of caring for graffiti writers follows a tradition of social work. This approach focuses the graffiti writers themselves and how to redirect them to accepted forms of artistic expression. The youth workers have good potential to make contact, but it seems difficult to establish long-term relations because graffiti writers themselves do not find it necessary to formalize graffiti as a scheduled activity. A conclusion made is that there is something locked up about graffiti issues because actors see graffiti from their "own" perspective, and at the same time they remain critical of alternative approaches. Somewhat contradictory to an interaction structured around distinctive perceptions, the study shows that actors express uncertainty about what they are doing. Such critical self-reflections seem to be perceived as personal objections and are not shared with others. This, together with the fact that interest in graffiti comes and goes in waves, adds ambivalence to the conflictual field of graffiti. The thesis ends with a hypothetical discussion of how the conflict level could change if graffiti would be met with a differentiated policy.
