- Description:
- The purpose of this thesis project is to create a reference guide that school counselors in the Los Angeles area can utilize to better understand eating disorders. The information will include specific types of eating disorders, as well as their symptoms and warning signs. Also mentioned, is how the school counselor can play a role in the life of a student who has an eating disorder. In addition to this project being a reference guide, there is also a short listing of referrals which includes support services for those who are suffering from an eating disorder.

- Description:
- This study investigated that the use of Floor time in a social-emotional skills group, would increase the emotional development of the group, and increase the spontaneous initiations within the group. The social skills group consisted of four children age three, diagnosed with autism. The group met for one hour a week, for eight weeks. During this time, the Floor time protocol was implemented. A pre-test and post-test video was taken of the children without any facilitation, to measure the emotional development and the total number of initiations within the group. Results indicate there was a significant amount of improvement. The group increased in their overall social-emotional developmental level, as well as their capacity to initiate more social interactions.

- Description:
- This graduate project designed and implemented a prototype of an easy-to-use, yet very versatile and powerful 20 sketcher and 30 interactive modeler for architects. The predominant concepts of the modeler design are a simplified and integrated GUI that supports MDI, a transparent 20 sketch board that imitates tracing paper, and efficient creation and modification of 30 objects. These concepts are proven to be feasible and valuable by the partial implementation. Lessons and experiences gained from the design and implementation processes are presented. This report also listed ideas for future enhancements.

- Description:
- Experimental and theoretical studies of the manner in which molecules are distributed amongst micelles are described. Micelles are spherical, when separated "compartments" in aqueous solution that have the ability to solubilize water insoluble molecules. Much work and speculation have appeared over the years concerning the number distribution of these solublizates. In this work, the technique of electron spin resonance has been employed to test the dogma that uncharged molecules distribute randomly i.e. according to the Poisson distribution. Unlike most experimental techniques, this technique offers the tremendous advantage of being able to separate the contributions due to singly, doubly, triply, etc. occupied compartments. We have proved that the experimental results are inconsistent with a random distribution, and that particle-particle interactions must be taken into account. These interactions were studied theoretically in the framework of the grand canonical ensemble and also in the framework of a new phenomenology which models the flow of particles into compartments under the influence of an impedance to entry. The number distributions are shown to be identical in both frameworks, allowing two physical views of the process and allowing calculations to be carried out by either technique. In addition to a formal repulsion between particles that might be expected, an attractive pairing potential for singly occupied micelles was necessary to explain the results. Both the attractive and repulsive parts of the potential are found to be the same for two different solubilizates.

- Description:
- In recent years, there has been a rapid increase in HIV infection rates among women. Young females in particular have been disproportionately affected. Current HIV prevention interventions fail to meet the needs of those young females who are at highest risk for HIV. Incarcerated female youth are at particularly greater risk due to their life circumstances and propensity to take risks. The current program is _different from other programs in that it strives to address HIV prevention within the context of interpersonal relationships rather than relying solely on knowledge acquisition and skills building. Objectives of the twelve-week curriculum are to increase self-esteem, increase self-efficacy, identify resources within themselves and the relationships in their lives, and learn effective communication skills.

- Description:
- The behavior of water flow through a rectangular open channel spillway with a stilling basin and step was analyzed using Excel and Visual Basic for Applications. All the parameters of the flow (such as critical flow, depths at key points, lengths of different segments) were calculated given a set of parameters. For the initial stilling basin design, the Froude number at the beginning of the jump and the length of the stilling basin after the jump were set. Also it was assumed that the flow will become "uniform" after the step. Given these parameters a flow profile was derived. To test the design for various conditions, the flow was decreased while the channel dimensions (such as total length of the spillway, step size) were left the same as the initial design to simulate seasonal flow changes. Then the new flow profile and Froude number at the beginning of the jump were determined as functions of flow rate.

- Description:
- Mexican-American immigrants have been key figures in one of the greatest migration occurrences in the United States. This population makes contributions to the culture, financial system, and employment industry of the United States. They are an ongoing influx of positive attributes and support to the wellbeing of the United States. Mexican-American immigrants are faced with various challenges as they take part in the employment arena. The career issues they encounter such as being expected to work in the secondary labor market, having minimal knowledge of their work environment, and limited employment experience affects their career paths. The purpose of this project is to assist Mexican-American immigrants with their career issues and have them learn through a career developmental process. The career development program will consist of eight weekly sessions that include one individualized session and seven group sessions. The program is geared to assist them through a career exploration process, to become knowledgeable of the world of work, to develop appropriate career decisions techniques, and make effective career plans. The program features experiential learning activities focused around John Holland's theory of types and Donald Super's life-span theory. It also provides them knowledge of employment information necessary to succeed in the labor market.

- Description:
- The purpose of this study is to examine protective factors of adolescent resiliency with a focus on educationally supportive parenting behaviors. It is a correlational study examining the effects of perceived academically supportive behaviors by parents (i.e. their monitoring behaviors, their involvement in school, their academic encouragement behaviors and their educational aspirations for their children) have on the academic motivation and educational aspirations of adolescents. Educational resiliency research is largely concerned with highlighting the malleable factors that increase resilience in adolescents from socially and economically disadvantaged backgrounds. Self-report data were collected from 376 first and second-generation Mexican-American high school students from one high school located in the San Fernando Valley of Los Angeles, California. A secondary data analysis was conducted using bivariate correlations and multiple regressions. Although the results indicated that generational status did not affect adolescents' perceptions about educational support from parents, all forms of support were significantly and positively correlated to both adolescent academic motivation and educational aspirations.

- Description:
- The purpose of this study is to examine group differences in attachment styles and relationship functioning among individuals with high and low psychopathic traits. It was hypothesized that individuals with high psychopathic traits would report greater incidence of dismissing attachment and a lower incidence of secure attachment, relationship satisfaction, and relational-anxiety as compared with individuals with low psychopathic traits. It was also hypothesized that high psychopathic traits will have greater negative associations with secure attachment, preoccupied attachment, fearful attachment, relationship satisfaction, and relational-anxiety, as well as a greater positive association with dismissing attachment as compared to lower levels of psychopathic traits. Procedures included recruitment of 117 undergraduate students and administration of several self-report measures. The high psychopathy group reported greater incidence of fearful attachment while the low psychopathy group reported greater incidence of secure attachment and relationship satisfaction. No significant group differences were found in relationships between psychopathy, attachment, relationship satisfaction, and relational-anxiety. Clinical implications are discussed.

- Description:
- Trellis-Coded Modulation (TCM) is a technique which combines channel coding and modulation for the transmission of digital signals over bandlimited channels. The basic idea is to use signal-set expansion to provide redundancy for coding, and to design coding and signal-mapping functions jointly so as to maximize directly the minimum Euclidean distance between coded signal sequences. The coding gain is achieved without sacrificing data rate or expanding bandwidth at the expense of increasing decoder complexity. Simple TCM schemes with 2 to 8 states can provide asymptotic coding gains of 3 dB compared to uncoded modulation. With more complex schemes, asymptotic coding gains of 6 dB can be realized. This paper describes the general principle and performance of conventional TCM schemes and the methods for maximizing such performance. Additional 1 to 2 dB gain can be obtained by introducing asymmetry to signal constellation or by transmitting multiple symbols per state transition. Performance improvement and drawbacks of these schemes are also discussed. The important effects of carrier-phase offset are presented. Problems arise when a carrier-modulated TCM signal is demodulated with a phase offset which could be caused by the inability of the phase-tracking scheme of the receiver to track phase disturbances instantly. Several concepts relating to the application of soft-decision maximum-likelihood Viterbi decoder are discussed. An example of soft-decision decoding of M-ary signals is also presented.
