Effectiveness of a Child-Centered Self-Reflective Play Therapy Supervision Model

Effectiveness of a Child-Centered Self-Reflective Play Therapy Supervision Model

Date: May 2000
Creator: Giordano, Maria A.
Description: This study investigated the effectiveness of a child-centered self-reflective play therapy supervision model with master's level counselor education graduate students. Specifically, this research determined if the self-reflective play therapy supervision model facilitated significant change in the master's level play therapists': (a) child-centered attitude; (b) knowledge of child-centered play therapy; and (c) confidence in applying play therapy skills. This study also measured change in the skills of: (d) tracking behavior, (e) reflecting content, (f) reflecting feelings, (g) facilitating decision-making and self-responsibility, (h) facilitating esteem-building and encouragement, (i) encouraging the child to lead, (j) setting limits, (k) ability to be congruent, (l) quality of non-verbal responses and (m) quality of verbal responses. The experimental group students (N=15) utilized a 15 week self-reflective play therapy supervision model. This model consisted of a manual that reviewed the rationale and utilization of six therapeutic responses of child-centered play therapy, self-assessment forms that were completed after reviewing weekly play therapy session videos and weekly group supervision. The control group (N=15) received supervision during the 15 weeks but did not use the manual or the self-assessment forms. Prior to working with their first client and again at the end of the semester practicum, the play therapy supervisees ...

An Analysis of Gay/Lesbian Instructor Identity in the Classroom

An Analysis of Gay/Lesbian Instructor Identity in the Classroom

Date: May 2008
Creator: Giovanini, Heather
Description: In this project I explore the connection between cultural and personal identity in the college classroom. Respondent interviews were conducted using open-ended questions, which began with a broad picture of the role the instructor played in the classroom and then focused more specifically on the issue of sexual orientation and the choices to disclose or not disclose orientation in the classroom. Thematic analysis was used to examine the interviews, upon the completion of the interviews being transcribed. RQ1: Do gay and lesbian instructors disclose their sexual orientation in the classroom? From this question, four themes emerged. These themes were disclosure not relevant, out of the classroom disclosure, students just know, and disclosure in the classroom. RQ2: What reasons do gay and lesbian instructors give for disclosing their sexual orientation in the classroom? Two themes, fears of disclosure and holding back, transpired from this question. RQ3: How do gay and lesbian instructors foster diversity in the classroom related to sexual orientation? Four themes were exposed from the question, and these themes were paradox of diversity, passing, mentoring, and identity not sexuality.

Empowering the Black Community Faith-Based Economic Development

Empowering the Black Community Faith-Based Economic Development

Date: August 2001
Creator: Gipson, Phillip E.
Description: This paper is addressed to the inner city and some suburban congregations seeking to express their faith through practical initiatives to revitalize their distressed communities. The paper seeks to inspire and instruct the reader with motivational stories containing illustrations of the valuable role that African-American congregations have played in stimulating economic development in their communities. The paper also shows the importance of African-Americans having some control over the flow of economic funds throughout the community. African-American churches in the inner city should undertake significant ventures in community economic development to minister to the temporal as well as the spiritual needs of their communities. This paper will demonstrate how the African-American church, with assistance from federal, state, local programs, and private concerns, can be effective in the urban revitalization.

Decoherence, Master Equation for Open Quantum Systems, and the Subordination Theory

Decoherence, Master Equation for Open Quantum Systems, and the Subordination Theory

Date: August 2005
Creator: Giraldi, Filippo
Description: This thesis addresses the problem of a form of anomalous decoherence that sheds light into the spectroscopy of blinking quantum dots. The system studied is a two-state system, interacting with an external environment that has the effect of establishing an interaction between the two states, via a coherence generating coupling, called inphasing. The collisions with the environment produce also decoherence, named dephasing. Decoherence is interpreted as the entanglement of the coherent superposition of these two states with the environment. The joint action of inphasing and dephasing generates a Markov master equation statistically equivalent to a random walker jumping from one state to the other. This model can be used to describe intermittent fluorescence, as a sequence of "light on" and "light off" states. The experiments on blinking quantum dots indicate that the sojourn times are distributed with an inverse power law. Thus, a proposal to turn the model for Poisson fluorescence intermittency into a model for non-Poisson fluorescence intermittency is made. The collision-like interaction of the two-state system with the environment is assumed to takes place at random times rather than at regular times. The time distance between one collision and the next is given by a distribution, called the ...

The Social Construction of Huntington's Disease Caregivers in Colombia, South America

The Social Construction of Huntington's Disease Caregivers in Colombia, South America

Date: December 2005
Creator: Giraldo, Clara
Description: This study is a multi-method, two-city, intensive, in-depth qualitative study of Huntington's disease (HD) caregivers (HDCs) in Colombia. I explored the Colombia HDCs' experience through the Hispanic culture of caring. I develop the theory of the subrogate agency based on 5 functional stages of HD from Shoulson and Fanh (1979). This study was conducted in two different regions of Colombia, Medellin and Juan de Acosta, in which high rates of HD cases have been identified. The data were collected through three methods: (a) 56 interviews with HDCs and 8 with physicians; (b) 28 participant observations of Huntington's disease sufferers (HDSs); (c) 4 interviews and 8 focus groups of 6 members each with HDCs of late HDSs. Human agency is the ability to monitor one's own action. This study showed that the gradual and serious loss of all capabilities in HDSs has a social effect on the HDSs' agency. HDSs' survival depends on the subrogation that the HDC offers to the HDS. The HDS retains self-hood, i.e. agency, through the HDC's action. This subrogation causes a paradoxical consequence, resulting in both negative and positive effects on the caregiver. The theory of surrogate agency is supported by the data. Through the progressive ...

Leadership Communication Among Kindergarten Children in a Structured Play Environment

Leadership Communication Among Kindergarten Children in a Structured Play Environment

Date: August 1995
Creator: Giraud, Jeffrey B. (Jeffrey Brian)
Description: This study examines the enactment of leadership communication during videotaped play sessions of thirty kindergarten children. Eighteen of the children demonstrated skills in a cluster of five specific leadership behaviors. All five coders agreed that these eighteen children were sometimes leaders of their individual triad. The coders further agreed that the leadership in the triads flowed from one child to another as the session progressed. The study concluded that leadership is a facilitative process that is fluid rather than statically centered in one or more participants.

Incremental Learning with Large Datasets

Incremental Learning with Large Datasets

Date: May 2012
Creator: Giritharan, Balathasan
Description: This dissertation focuses on the novel learning strategy based on geometric support vector machines to address the difficulties of processing immense data set. Support vector machines find the hyper-plane that maximizes the margin between two classes, and the decision boundary is represented with a few training samples it becomes a favorable choice for incremental learning. The dissertation presents a novel method Geometric Incremental Support Vector Machines (GISVMs) to address both efficiency and accuracy issues in handling massive data sets. In GISVM, skin of convex hulls is defined and an efficient method is designed to find the best skin approximation given available examples. The set of extreme points are found by recursively searching along the direction defined by a pair of known extreme points. By identifying the skin of the convex hulls, the incremental learning will only employ a much smaller number of samples with comparable or even better accuracy. When additional samples are provided, they will be used together with the skin of the convex hull constructed from previous dataset. This results in a small number of instances used in incremental steps of the training process. Based on the experimental results with synthetic data sets, public benchmark data sets from ...
