My question here revolves around my orientation with my own work; my own frustrations and inability to so often answer the question “can a meaningful place be designed?” This journey examines the theory of semiotics. Through this, three strategies have been developed to explore the branches of semiotic research in Landscape Architecture. The first strategy allows meaning to develop through time, and it is with the repeated usage of people that meaning will accrue. The second strategy shows how meaning can be determined before the design through mapping current and desired locations of meaning in space. And, the third strategy reflects on how meaning emerges from the earth when no interference from designers or users occurs. The result of the three individual strategies is a combination of solutions, illustrating how to create places of true richness. This new space will engage visitors, pull in new visitors, and help create something memorable for those engaging in a space. / October 2008

This thesis proposes a classification system of risk mitigation strategies based on literature search and industry interviews. Following that, a list of generic properties was generated to describe individual strategies. In parallel, populating the properties of a large number of identified strategies was attempted. The practical implications are discussed mainly focusing on knowledge management for risk mitigation strategies.

Introduction: According to the CDC (2008), tobacco-related deaths out number deaths from alcohol use, motor vehicle injuries, suicides, murders, human immunodeficiency virus (HIV), and illegal drug use. One out of every five deaths in the United States can be attributed to tobacco, culminating in a staggering 443,000 deaths in the US every year. Smoking is also the leading preventable cause of death in America (CDC, 2008). In 2006, the Surgeon General’s Report speaks to not only the detrimental effects of smoking, but also the harmful effects second hand smoke can have on an individual’s health. Furthermore, the Centers for Disease Control’s Office of Smoking and Health reported that 49,400 deaths every year in the US are the result of second hand smoke exposure, of which 46,000 will have died from heart disease attributable to second hand smoke in the environment in which they live, work, play, and learn (CDC, 2008). While the negative health outcomes with tobacco use have inundated mainstream media and literature, tobacco use has another large and devastating effect on communities around the world. That effect is the result of Tobacco Product Litter (TPL). Beyond the unsightliness of TPL, several other unwanted complications to society result from the disregarded refuse, such as harm to the environment and damages incurred by other businesses not associated at all with tobacco products. Rationale for Intervention: First and foremost the Tobacco-Free GSU Initiative was intended to promote the health of the Georgia State University community consisting of students, faculty, and staff. The American College Health Association (2009) recommends 100% tobacco-free campuses, indoors and outdoors. Studies have shown that non-smokers and smokers attending college are in favor of campus policies that control the use of tobacco on campus (Rigotti, Regan, Moran, et al., 2003; Thompson B, Coronado GD, Chen L, et al., 2006). Sawdey et al. (2011) cites the need for the implementation of smoke-free policies by campuses in order to utilize the opportunity to create an atmosphere conducive to tobacco cessation. Considering that one third of young Americans attend a college or university (Rigotti et al., 2003), exposing one third of the youth population of the United States to a tobacco-free environment could potentially change the socially acceptable norms of using tobacco, whist simultaneously creating an environment free of TPL. Intervention Strategy Analysis: Tobacco-Free GSU utilized a methodology similar to the strategies Glassman, Reindel and Whewell outlined in their 2011 study Strategies for Implementing a Tobacco-Free Campus. The Glassman et al. (2011) strategy included: Creating a Committee, Utilizing a Student Debate, Publicity, Drafting of a Potential Policy, Targeting the College or University Board of Trustees, Addressing Barriers to Becoming Tobacco-Free, Student Involvement, Administrative and Staff Support, Resources, and Enforcement Conclusion: In order to facilitate the best possible outcome, this author recommends those seeking to create a tobacco-free campus utilize the strategies outlined throughout this document, whilst creating strategies specific to their location, population, and situation.

The present review focuses on understanding the explanatory mechanisms behind the use of violence within intimate relationships, highlighting the consequences of adolescents’ exposure to Inter-parental violence and gauging the role of their (adolescents) appraisal and coping strategies. The theories reviewed stress the significant impact of close figures’ behaviors on the developing child and adolescent trough observational and imitational processes, secure and insecure attachment patterns and related internal working models as well as trough building own understanding of the world and human interrelations. The review revealed also that adolescents’ exposure to Inter-parental violence constituted an unequivocal risk factor leading to a range of consequences categorized as internalizing and externalizing problems. It however indicates that the outcome behaviors are not a result of a linear process because there is range of mediating factors that explain the association between adolescents’ exposure to Inter-parental violence and outcome behaviors. Finally, appraisal of Inter-parental violence was identified as a central mechanism that impacts both the magnitude of the consequences of exposure and the adolescents’ conception and execution of coping strategies.

La electroforesis capilar presenta menos sensibilidad en términos de concentración, comparado con la cromatografía de líquidos debido principalmente al pequeño volumen de inyección de la muestra y a la pequeña longitud del camino óptico para la detección, el cual coincide con el diámetro interno del capilar. El objetivo de la presente Tesis es el estudio y desarrollo de diferentes estrategias para disminuir los límites de detección de la electroforesis capilar, concretamente técnicas de preconcentración electroforéticas y cromatográficas. Se presentan técnica basadas en isotacoforesis y SPE acoplado en línea a electroforesis capilar para la determinación de drogas de abuso y de anti-inflamatorios no esteroidales. El desarrollo fundamental de estas estrategias va, en muchos casos, relacionado con el desarrollo de las aplicaciones, por lo cual el trabajo con muestras reales es fundamental, concretamente se ha trabajado con muestras biológicas (plasma y orina) y con muestras de agua medioambientales (agua de rio y de grifo). / Capillary electrophoresis is a highly promising analytical separation technique with a wide range of applications in biological and environmental fields. However, Capillary electrophoresis suffers from a lack of sensitivity when compared with chromatographic techniques because, in general, it is not possible to inject high sample volumes and also due to the short optical path-length for on-capillary detection. The objective of this Doctoral Thesis is the development of analytical methods to increase sensitivity in capillary electrophoresis for the determination of pharmaceuticals and drugs of abuse in environmental and biological samples. To do that, several preconcentration techniques either stacking (based on isotachophoresis principles) or chromatographic (based on in-line SPE) have been studied. The compounds selected for the different studies in this Doctoral Thesis belong to the pharmaceutical compound group (in particularly in non-steroidal anti-inflammatory drugs) and to the drugs of abuse group.

The 21st century mathematics classroom looks and operates differently than it did half a century ago. Not only are teachers expected to facilitate activities rather than lecture, they are also expected to utilize technology. The National Council of Teachers of Mathematics established the technology principle to guide teachers into this practice in 2000. Today there are middle school mathematics teachers who use technology effectively in the classroom. However, there is a dearth of literature in this area on how they select and use technology. The purpose of this qualitative study is to understand the process by which these teachers select and use technology in their classroom. Activity theory and teacher thinking process model provided a conceptual framework for this study. The guiding research questions are: (1) How do successful urban middle grades mathematics teachers, who use technology effectively, describe their teaching practices? (2) What are the strategies teachers use when integrating technology effectively in the classroom? Using a case study approach, the researcher collected data over 4 months from 3 urban middle school teachers – one on each grade level 6th, 7th, and 8th. Data sources included lesson plans, semi-structured interviews, and classroom observations. Findings revealed that teachers consider the types of learners when deciding what technology is appropriate to use. Teachers also preview technology prior to using it in the classroom. Emerging themes were grouped in five categories to describe how teachers plan and implement technology effectively. They are preparation, engagement, assessment, communication, and evaluation. The research findings give strategies to support teacher’s decisions about using technology for all types of learners and how to be effective in every phase of learning – whether it is introducing a lesson, remediating skills, or assessing knowledge. These findings also enable stakeholders to make informed decisions about technology in their school so that teachers will be able to elevate the quality of instruction with appropriate technology resources. Extended research should measure the impact that technology has on student learning. The likelihood of teachers using technology and using it more often would increase at a faster rate if there is evidence that the growth of student achievement occurs more rapidly when using technology.

The research conducted in this thesis is centered on the ESOL Hispanic student population, in the art classroom in Georgia. The information contained in this paper is meant to serve as a guide and resource for art educators with high populations of ESOL students in their classrooms. A review of current ESOL best practices in several content areas is included. Based on the research, guidelines and suggestions for accommodating these learners in the art room were developed, as well as a sample unit that includes three lesson plans, PowerPoint presentations and assessment rubrics.

The advancement in technology in the twenty first century has introduced new and exciting ways for artists to self-promote their artwork while traditional methods remain viable. To be competitive in the art market an artist must understand and implement a variety of marketing strategies. Effective marketing is particularly critical for an art teacher who is also a practicing artist in order to sell their artwork. Through a comparative analysis of readily available marketing tools for artwork, I explore in this study a variety of ways that an artist can establish a successful career in art through the use of technology, and create a roadmap that can be used to shorten their route.

WORD READING STRATEGY DEVELOPMENT OF DEAF AND HARD-OF-HEARING PRESCHOOLERS by Victoria Burke Siegler’s (1996) overlapping waves model of strategy development applied to reading posits that children use multiple strategies to read words from the earliest stage of reading development, that these strategies coexist over a long period of time, and that experience results in gradual change in the strategies children use and the effectiveness with which they are executed. Phonological recoding is one of the most effective early developing reading strategies and is predictive of future reading success for hearing children (Ehri, 2005; Juel & Mindencupp, 2000; Share & Gur, 1999). However, less is known regarding the extent to which young children who are deaf and hard of hearing (DHH) develop and use phonological strategies to read words. Due to technological advances such as cochlear implants and digital hearing aids, many DHH children have sufficient functional hearing to be able to perceive and represent spoken language. For these children, beginning reading strategies may resemble those of hearing children (Geers, Tobey, Moog, & Brenner, 2008; Lederberg, Schick, & Spencer, in press). The purpose of this study was to describe changes in the word reading strategies of 15 DHH preschoolers with functional hearing. These children received explicit instruction in alphabetic knowledge, phonological awareness, and early reading strategies in a year-long intervention. Instruction was videotaped and children’s overt behavior while independently reading words was coded for reading strategy and accuracy. The preschoolers used multiple reading strategies at all times including two phonological recoding strategies (segmenting phonemes only, segmenting and blending phonemes) and retrieval. Gradual change was observed in strategy choice, execution, and accuracy. Children’s use of segmenting only decreased while segmenting and blending phonemes increased between the beginning and middle of the year. Retrieval use increased between the middle and end of the year. Execution of phonological strategies gradually improved over the year. These results suggest young DHH children who have functional hearing develop and use strategies in a manner similar to hearing children and benefit from explicit instruction in the alphabetic principle.

This thesis identifies and analyzes successful movement strategies for the completion of a complex dynamic task. In the past it has been shown that movement strategies correlate well to performance for simple tasks. Therefore, in this thesis I was motivated to find out if motion based metrics correlated well to performance for more complicated motor tasks. First, the Nintendo Wiimote was verified as a suitable gaming interface enabling gross human motion capture through experimental comparisons with other gaming interfaces and precision sensors. Then, a complex motor task was rendered in an open-source gaming environment. This environment enabled the design of a rhythmic task that could be controlled with the Wiimote while data were simultaneously recorded for later analysis. For the task, success and failure could be explained by high correlation between two motion based performance metrics, mean absolute jerk (MAJ) and average frequency (AVF) per trial. A logistic regression analysis revealed that each subject had a range of MAJ and AVF values for being successful, outside of which they were unsuccessful. Therefore, this thesis identifies motion based performance metrics for a novel motor control task that is significantly difficult to master and the techniques used to identify successful movement strategies can be used for predicting success for other such complex dynamic tasks.
