The investigation was first to identify the antecedents and changes in urban space prior to this vertical integration, in this way, we tried to understand how the city was transformed with the spread of residential buildings. Then, the study sought to identify the legal aspects that influenced or were influenced by vertical integration, and how these laws led to distribution of the buildings around the city. Later the analysis is reported to the resulting city, before and after this process, the regions that most changed in type of housing were mapped and the neighborhoods that most increased in the number of apartments were identified. The study of average income and density were essential to establish the direct relationship of these with the process of vertical integration and the research aimed to identify the correspondence between the city designed by the legislation and the result diagnosed. This study suggests that the interference of the legislation is much more significant in the development of buildings of projects than actually in the definition of urban space, and that the distribution of the buildings in the city, receives more influence of the real estate market than of the legislation itself. / A pesquisa estuda o processo de verticalização no Município de Fortaleza, no período de 1979 até 2009. A investigação se inicia com a identificação dos antecedentes e das alterações do espaço urbano que precederam o processo de verticalização. Desta forma, vai-se compreendendo como a cidade foi se transformando com a disseminação dos edifícios residenciais. Em seguida, o trabalho identifica os aspectos legais que mais influenciaram ou foram influenciados pela verticalização, e como essas leis interferem na distribuição dos prédios pela cidade. Posteriormente, a análise se reporta à cidade resultante, antes e após este processo. Foram mapeadas, então, as regiões que mais sofreram mudanças no tipo de moradia e identificados os bairros que mais apresentaram crescimento no número de apartamentos. O estudo da média de renda e da densidade foi fundamental para constatar a relação direta destas com o processo de verticalização e procurar identificar a correspondência entre a cidade pensada pela legislação e o resultado diagnosticado. Este estudo sugere que a interferência da legislação é muito mais significativa no desenvolvimento dos projetos das edificações do que propriamente na definição do espaço urbano, e que a distribuição dos prédios na cidade recebe maior influência do mercado imobiliário do que propriamente da legislação.

The purpose of this dissertation study was to critically examine college student alcohol use in the context of the microenvironment of residence halls, the transition of the national minimum legal drinking age, and the attitudes and experiences of University of Iowa students who lived on campus from 1980 to 1995. The following research questions guided this study: 1) What were the attitudes and experiences of students living in the University of Iowa residence halls before, during, and after the change in the national minimum legal drinking age? 2) What were the individual experiences of students in the residence halls, in particular their alcohol behaviors? 3) What were students' attitudes towards policies and rules regarding alcohol? 4) How did non-residential students or staff members view student alcohol behaviors within the residence halls? 5) How might this information provide context and inform our understanding of the culture and environment we have on campus today? This study merged nested case study, historical methods, and oral history in order to address the research questions and best represent individual attitudes and experiences. Existing research on college student alcohol use and the influences of environment and peer groups, as well as the researcher's own background, informed and framed the study. Qualitative data sources for this study included nineteen participants, who were students, staff members, or administrators during the 1980s and 1990s. Guided interviews combined with artifact analysis were employed. Four over-arching themes emerged as a result of participants' attitudes and experiences provided during interviews: culture, residence halls, permissiveness, and sociability. Lessons learned include the importance of the culture and environment, the influence of residence halls norms, and the role of the university in shaping college student alcohol use. The national minimum legal drinking age transition seemed to affect few, if any, of my participants. My participants' attitudes and experiences during the time period of 1980 to 1995 did not depend on what year my participant was on campus in relation to the national minimum legal drinking age as all my participants faced similar experiences throughout the years of my study. The time period on campus was not as significant in shaping experiences as was the culture that had developed over time.

This dissertation was the first study to estimate the direct and indirect effects of living-learning community (LLC) participation on a standardized measure of critical thinking using a multi-institution longitudinal research design. It is possible that despite being lauded nationally as an effective institutional intervention, LLCs may simply cluster students predisposed to be more engaged with their environment, more academically prepared, and more open to growth compared with traditional residence hall peers. Recent studies have demonstrated a positive relationship between LLC participation and self-reported growth in critical thinking. The findings of this study demonstrate markedly different conclusions from previous LLC studies exploring the outcome of critical thinking. The results of this study suggest that net of academic ability and background and institutional characteristics, students who participated in LLCs did not demonstrate greater gains on a standardized measure of critical thinking than their peers in traditional residence hall environments. To investigate the relationship between LLC participation and growth in critical thinking, I performed secondary data analysis from the 2006, 2007, and 2008 cohorts of the Wabash National Study of Liberal Arts Education - a longitudinal study of teaching practices, programs, and institutional structures that support liberal arts education. From the initial 53 colleges and universities in the WNSLAE study, I selected a sub-sample of 19 institutions with formal LLC programs to make a more conservative estimate of the reliability of participation in an LLC. The final sub-sample included 435 (25%) students in the experimental group (students participating in LLCs) and 1,282 (75%) students in the control group (students living in traditional residence halls). This study makes four important contributions to the literature on LLC. First, the longitudinal nature of the WNSLAE data allowed for an estimate of growth during the first-year of college and controls for students' self-selection into the experimental or control groups. Second, the critical thinking module of the Collegiate Assessment of Academic Proficiency allowed for an objective measure compared to previous studies that use students' self-reports. Third, this was the first multi-institution LLC study to include liberal arts colleges in the sample. LLCs at liberal arts colleges did not demonstrate a differential impact compared with LLCs at regional and research universities on students' growth in critical thinking. Finally, post hoc analysis did not demonstrate conditional differences of LLC impact between students background, institutional characteristics, or the degree of faculty and peer interaction.

The study sought to investigate the nature of learning that occurs in two different approaches (integrated and non-integrated) to an artist-in-residency program. The program was conducted in middle phase schooling, and adopted the principles of authentic learning. Two year five classes and their teachers participated in the study. The residency provided learning experiences that connected to the curriculum unit theme for one year five class (integrated), but not for the other year five class (non-integrated). These experiences were designed to relate to the learner's lived experiences and promote higher-order thinking processes. The study sought to explore the potential for visual arts residencies to foster more 'authentic' modes of learning. The study examined children's ability to transfer knowledge, gained through the visual and verbal analysis of images, by manipulating and integrating diverse information and ideas. Grounded Theory was deemed to be an appropriate research methodology for this study as it involves gathering data in field settings and applying inductive methods to analyze this data. Diverse data collection strategies were implemented including: teacher stories, interviews, student reflection, researcher observations and student artworks. LeximancerTM software was selected as an instrument for analyzing data. This software was considered appropriate as it fosters a descriptive and interpretive approach to analysis. The findings of the study indicated that children who participated in the integrated artist-in-school's curriculum program demonstrated more evidence of higher-order thinking processes than children who participated in the non-integrated program. The participants undertaking the integrated approach were able to establish relatively complex relationships between the central residency concepts, demonstrating an ability to use visual and verbal codes of communication to articulate their ideas, knowledge and experiences. A further important finding identified positive student behavioural outcomes, where the integrated residency approach appeared to connect group members as small supportive learning communities. The study also identified a transition in the teacher's perspectives on teaching and learning after participating in the integrated approach. This research project has significance both nationally and internationally by investigating current practices in artist-in-schools programs that both enhance and hinder educational outcomes. The study has significance to the broader educational community in terms of its focus on the role of visual arts specialist adjuncts in maximising learning outcomes. The findings of this study could provide insight into the interrelationship between visual arts and other curriculum areas to heighten student learning outcomes. The findings of the study illustrate how particular approaches to visual art in education can enhance children's learning and development. These insights can assist artists undertaking residencies in schools, and the teachers involved, to provide richer learning experiences. The findings provide ifirther evidence to support an approach that involves close collaboration between resident artists and educators. It is recommended that the residency learning experiences are connected to the children's lived experiences and that there is social support from teachers, parents and peers. It is also argued that for a residency to be considered 'authentic', the approach requires a number of essential and valuable attributes. These essential and valuable attributes have two tiers of application which coalesce to contribute to the efficacy of a school art residency.

The current work has developed a CFD model to characterise a pseudo-annular photocatalytic bubble column reactor. The model development was divided into three stages. Firstly, hydrodynamic assessment of the multiphase fluid flow in the vessel, which incorporated residence time distribution analysis both numerically and experimentally for validation purposes. Secondly, the radiation distribution of the UV source was completed. The final stage incorporated the kinetics for the degradation the model pollutant, sodium oxalate. The hydrodynamics were modelled using an Eulerian-Eulerian approach to the multiphase system with the standard k- turbulence model. This research established that there was significant deviation in the fluid behaviour in the pseudo-annular reactor when compared with traditional cylindrical columns due to the nature of the internal structure. The residence time distribution study showed almost completely mixed flow in the liquid phase, whereas the gas phase more closely represented plug flow behaviour. Whilst there was significant dependence on the superficial gas flow rate the mixing behaviour demonstrated negligible dependence on the liquid superficial velocity or the liquid flow direction, either co- or counter- current with respect to the gas phase. The light distribution was modelled using a conservative variant of the Discrete Ordinate method. The model examined the contribution to the incident radiation within the reactor of both the gas bubbles and titanium dioxide particles. This work has established the importance of the gas phase in evaluating the light distribution and showed that it should be included when examining the light distribution in a gas-liquid-solid three-phase system. An optimal catalyst loading for the vessel was established to be 1g/L. Integration of the kinetics of sodium oxalate degradation was the final step is developing the complete CFD model. Species transport equations were employed to describe the distribution of pollutant concentration within the vessel. Using a response surface methodology it was shown that the reaction rate exhibited a greater dependency on the lamp power that the lamp length, however, the converse was true with the quantum efficiency. This work highlights the complexity of completely modelling a photocatalytic system and has demonstrated the applicability of CFD for this purpose.

<p>The hypothetical assumption that chloride is conservative in the soil has been debated for the last decade. The results of the recent years of study in chlorine biogeochemistry show that chloride is non-conservative but rather participates in complex biogeochemical reactions in the soil. These interactions in nature inform the development of simplified hydrochemical model of chloride dynamics in the soil that is driven on soil routine component of HBV hydrological model. This novel attempt affords the opportunity to explore chlorine biogeochemistry further by evaluating the biological processes such as microbial biomass that predominate chlorine cycles in the same order of magnitude as earlier studied abiotic factors. Data from soil lysimeter experiment with different inputs treatments were used in the calibration and validation of both the hydrological and biogeochemical model. The results show that (1) model efficiency reduces with decreasing water residence and with increasing soil organic matter. (2) Longer water residence time (low water input), high chloride and high nitrogen input loads relatively enhance maximum biomass accumulation in a shorter time span. (3) Chloride retention time reduces with increasing chloride loads under short water residence. (4) Microbial biomass growth rate is highest under high chloride input treatments. (5) Biomass death rates shows reducing trend under short water residence (High water input). Further researches are therefore suggested for possible model expansion and to make the results of this model plausible under field conditions.</p>

The Altiplano-Puna Volcanic Complex in the Central Andes is one of the youngest large silicic volcanic fields (LSVFs) in the world, erupting over 13,000 km³ of material during multiple supereruptions from 11 to 1 Ma. Understanding the timescales over which magma is stored in the crust prior to eruption is crucial to understanding the development of LSVFs such as the APVC. The residence time of a magma is defined as the time between magma formation and its eruption. While the eruption age of a volcanic system is generally well constrained through ⁴⁰Ar/³⁹Ar dating of sanidine and biotite crystals, determining the time of magma formation offers a bigger challenge. U-Pb dating of zircon—an early crystallizing, ubiquitous phase in silicic systems—is a commonly used method for determining the timing of magma formation. U-Pb zircon ages were collected for 16 ignimbrites representing the temporal and spatial distribution of the APVC. Zircon crystallization histories show significant overlap between eruptive centers of similar age separated by as much as 200 km. Ignimbrites erupted from the same multicyclic caldera show little relationship. This suggests that ignimbrites may share a deeper, regional source. Timescales of zircon crystallization for individual ignimbrites range from ~400 ka to more than 1 Ma, with little correlation with age or erupted volume. Ignimbrites with longer crystallization timescales frequently exhibit a stepped age distribution and highly variable U contents, suggesting that these ignimbrites likely formed in a very crystalline, low melt fraction environment while ignimbrites with short crystallization times and constrained U concentrations crystallized in high melt fraction systems. Zircon crystallization histories record periods of continuous zircon crystallization in the APVC that extend over 1.5-2 Ma pulses and correlate well with eruptive pulses recognized by previous studies. Overall, zircon crystallization histories of the magmas feeding ignimbrite eruptions in the APVC record long timescales of magmatic activity from a shared regional source, likely the Altiplano-Puna Magma Body currently detectable underlying the APVC. / Graduation date: 2012

This study examined the multicultural counseling competence among new residence life professionals by using the Multicultural Counseling Knowledge and Awareness Scale (MCKAS: Ponterotto, Gretchen, Utsey, Riger, & Austin, 2002) and a demographic questionnaire created by the researcher. Results included statistically significant positive relationships between participants’ completion of multicultural counseling graduate coursework and multicultural knowledge, quantity of field experiences and multicultural knowledge, and race and multicultural awareness. A negative relationship was discovered between the frequency of travel experiences outside country of birth and multicultural knowledge. Implications of these findings for field of Student Affairs and suggestions for future research are discussed.
