Description
Two critical limitations for hyperspatial imagery are higher imagery variances and large data sizes. Although object-based analyses with a multi-scale framework for diverse object sizes are the solution, more data sources and large amounts of testing at high costs are required. In this study, I used tree density segmentation as the key element of a three-level hierarchical vegetation framework for reducing those costs, and a three-step procedure was used to evaluate its effects. A two-step procedure, which involved environmental stratifications and the random walker algorithm, was used for tree density segmentation. I determined whether variation in tone and texture could be reduced within environmental strata, and whether tree density segmentations could be labeled by species associations. At the final level, two tree density segmentations were partitioned into smaller subsets using eCognition in order to label individual species or tree stands in two test areas of two tree densities, and the Z values of Moran's I were used to evaluate whether imagery objects have different mean values from near segmentations as a measure of segmentation accuracy. The two-step procedure was able to delineating tree density segments and label species types robustly, compared to previous hierarchical frameworks. However, eCognition was not able to produce detailed, reasonable image objects with optimal scale parameters for species labeling. This hierarchical vegetation framework is applicable for fine-scale, time-series vegetation mapping to develop baseline data for evaluating climate change impacts on vegetation at low cost using widely available data and a personal laptop.

Description
It has been identified in the literature that there exists a link between the built environment and non-motorized transport. This study aims to contribute to existing literature on the effects of the built environment on cycling, examining the case of the whole State of California. Physical built environment features are classified into six groups as: 1) local density, 2) diversity of land use, 3) road connectivity, 4) bike route length, 5) green space, 6) job accessibility. Cycling trips in one week for all children, school children, adults and employed-adults are investigated separately. The regression analysis shows that cycling trips is significantly associated with some features of built environment when many socio-demographic factors are taken into account. Street intersections, bike route length tend to increase the use of bicycle. These effects are well-aligned with literature. Moreover, both local and regional job accessibility variables are statistically significant in two adults' models. However, residential density always has a significant negatively effect on cycling trips, which is still need further research to confirm. Also, there is a gap in literature on how green space affects cycling, but the results of this study is still too unclear to make it up. By elasticity analysis, this study concludes that street intersections is the most powerful predictor on cycling trips. From another perspective, the effects of built environment on cycling at workplace (or school) are distinguished from at home. This study implies that a wide range of measures are available for planners to control vehicle travel by improving cycling-level in California.

ABSTRACT (English)
Heinrich Hoffmann`s renowned Struwwelpeter and the famous Grimm brothers' fairy tales have been the subject of exhaustive pedagogical and psychological scrutiny. By means of shocking and fascinating literary elements Struwwelpeter's revolutionary didactic horror-comedy as well as the instructive horror-fantasy inherent in fairy tales are able to cast an enchanting, enlightening spell on their audience. However, both Hoffmann's and the Grimm's adventurous stories have suffered harsh criticism particularly owing to their often gruesome, macabre and unrealistic subject matter. Notwithstanding the barrage of denunciating objections, the remarkable longevity of Fidgety Philip, Little Red Riding Hood and Co appears to know no bounds, as their ingenious formula for success comprising captivatingly shocking, spine-tingling elements of both entertaining and educational value continues to inspire contemporary adaptations. Several German dialects have also discovered and devoted themselves to the magical world of Hoffmann's chaotic rascals and the Grimm's fascinating fairy tale characters in furtherance of enlivening them with the identity, culture and local flavor of their respective region.
The current study aims to demonstrate the extent to which dialectal adaptations of the aforesaid tales succeed in not only revitalizing the original narratives including their pedagogical and psychodynamic quintessence but also in capturing the readers' hearts by virtue of their intimate parlance/phraseology. This particular philological approach illustrates the symbiotic interaction between regional German dialects and well-known (children's) Horror-stories.
ABSTRACT (German)
Bisher waren sowohl der renommierte Struwwelpeter Heinrich Hoffmanns als auch die berühmten Märchen der Brüder Grimm Objekte erschöpfender pädagogischer und psychologischer Betrachtungen. Die revolutionäre didaktische Gruselkomik der struwwelpetrigen Abenteuer sowie die lehrhafte Gruselphantastik der Märchen vermögen vermittels ihrer schockierenden und zugleich faszinierenden Elemente Menschen jeden Alters in ihren verzaubernden, lebenserhellenden Bann zu ziehen. Allerdings mussten die hoffmannschen und grimmschen Geschichten insbesondere auf Grund grausamer, wirklichkeitsfremder Inhalte auch als Zielscheibe heftigster Kritik fungieren. Nichtsdestotrotz scheint der steilen Karriere von Zappelphilipp, Rotkäppchen und Co keine Grenzen gesetzt, denn ihre raffinierte Erfolgsformel bestehend aus unterhaltsam-belehrenden Schock- und Zaubermotiven inspiriert stets neue Adaptionen. So haben auch die deutschsprachigen Mundarten längst das skurille sowie zauberhafte Reich der chaotischen Lausbuben und Märchencharaktere für sich entdeckt, um diese mit der jeweils eigenen regionalkolorierten Identität und Kultur zu beseelen.
Im Rahmen dieser Arbeit gilt es nun zu demonstrieren, inwiefern es den dialektalen Petriaden und Märchenversionen gelingt, nicht nur die Erzählungen samt ihrer pädagogisch sowie psychodynamisch wertvollen Kerngehalte zu neuem Leben zu erwecken, sondern sich darüber hinaus in anheimelnder Weise die Herzen der Leserschaft zu erobern. Diese einzigartige philologische Perspektive beleuchtet die Erfolg versprechende Wechselwirkung zwischen den ortsspezifischen Sprachgeflechten und den (Kinder)-Gruselklassikern.

Description
With the ongoing drought surpassing a decade in Arizona, scholars, water managers and decision-makers have heightened attention to the availability of water resources, especially in rapidly growing regions where demand may outgrow supplies or outpace the capacity of the community water systems. Community water system managing entities and the biophysical and social characteristics of a place mediate communities' vulnerability to hazards such as drought and long-term climate change. The arid southwestern Phoenix metropolitan area is illustrative of the challenges that developed urban areas in arid climates face globally as population growth and climate change stress already fragile human-environmental systems. This thesis reveals the factors abating and exacerbating differential community water system vulnerability to water scarcity in communities simultaneously facing drought and rapid peri-urban growth. Employing a grounded, qualitative comparative case study approach, this thesis explores the interaction of social, biophysical and institutional factors as they effect the exposure, sensitivity and adaptive capacity of community water systems in Cave Creek and Buckeye, Arizona. Buckeye, once a small agricultural town in the West Valley, is wholly dependent on groundwater and currently planning for massive development to accommodate 218,591 new residents by 2020. Amid desert hills and near Tonto National Forest in the North Valley, Cave Creek is an upscale residential community suffering frequent water outages due to aging infrastructure and lack of system redundancy. Analyzing interviews, media accounts and policy documents, a narrative was composed explaining how place based factors, nested within a regional institutional water management framework, impact short and long-term vulnerability. This research adds to the library of vulnerability assessments completed using Polsky et al.'s Vulnerability Scoping Diagram and serves a pragmatic need assisting in the development of decision making tools that better represent the drivers of placed based vulnerability in arid metropolitan regions.

Description
At first glance, trends in increased hunger and obesity in the United States (US) would seem to represent the result of different causal mechanisms. The United States Department of Agriculture (USDA) reported that nearly 50 million Americans had experienced hunger in 2009. A year later, the Centers for Disease Control and Prevention published a report showing that 68% of the US population was either overweight or obese. Researchers have found that these contrasting trends are actually interrelated. Being so, it is imperative that communities and individuals experiencing problems with food security are provided better access to healthy food options. In response to the need to increase healthy food access, many farmers markets in the US have received funding from the USDA to accept vouchers from federal food security programs, such as the Supplemental Nutrition Assistance Program (SNAP). In Downtown Phoenix, Arizona, one organization accepting vouchers from several programs is the Phoenix Public Market. However, the mere existence of these programs is not enough to establish food security within a community: characteristics of the population and food environments must also be considered. To examine issues of food security and public health, this thesis utilizes geographical information systems (GIS) technology as a tool to analyze specific environments in order to inform program effectiveness and future funding opportunities. Utilizing methods from community-based participatory research (CBPR) and GIS, a mapping project was conducted in partnership with the Market to answer three questions: (1) what is the demographic makeup of the surrounding community? (2) What retailers around the Market also accept food security vouchers? And (3) where are food security offices (SNAP and WIC) located within the area? Both in terms of demographic characteristics and the surrounding food environment, the project results illustrate that the Market is embedded within a population of need, and an area where it could greatly influence community food security.

Description
Accurate characterization of forest canopy cover from satellite imagery hinges on the development of a model that considers the level of detail achieved by field methods. With the improved precision of both optical sensors and various spatial techniques, models built to extract forest structure attributes have become increasingly robust, yet many still fail to address some of the most important characteristics of a forest stand's intricate make-up. The objective of this study, therefore, was to address canopy cover from the ground, up. To assess canopy cover in the field, a vertical densitometer was used to acquire a total of 2,160 percent-cover readings from 30 randomly located triangular plots within a 6.94 km2 study area in the central highlands of the Bradshaw Ranger District, Prescott National Forest, Arizona. Categorized by species with the largest overall percentage of cover observations (Pinus ponderosa, Populus tremuloides, and Quercus gambelii), three datasets were created to assess the predictability of coniferous, deciduous, and mixed (coniferous and deciduous) canopies. Landsat-TM 5 imagery was processed using six spectral enhancement algorithms (PCA, TCT, NDVI, EVI, RVI, SAVI) and three local windows (3x3, 5x5, 7x7) to extract and assess the various ways in which these data were expressed in the imagery, and from those expressions, develop a model that predicted percent-cover for the entire study area. Generally, modeled cover estimates exceeded actual cover, over predicting percent-cover by a margin of 9-13%. Models predicted percent-cover more accurately when treated with a 3x3 local window than those treated with 5x5 and 7x7 local windows. In addition, the performance of models defined by the principal components of three vegetation indices (NDVI, EVI, RVI) were superior to those defined by the principal components of all four (NDVI, EVI, RVI, SAVI), as well as the principal and tasseled cap components of all multispectral bands (bands 123457). Models designed to predict mixed and coniferous percent-cover were more accurate than deciduous models.

Description
Many alternative schools for at-risk students do not offer art classes to their students. Phoenix Job Corps is one of those schools. I conducted a qualitative study about a voluntary summer art course at Phoenix Job Corps, a vocational school for at-risk students. I had thirteen student volunteers, eight of them refugees from other countries. All the participants created a narrative painting about something in their lives. The purpose of this study was to examine this voluntary summer art course and to determine its usefulness as a beneficial tool to the lives of the students. This included looking at participants' narrative paintings to determine common themes or subjects, finding out their opinions on whether or not their school should offer an art course, their willingness to share their stories, determining whether they think it's important for others to see their work, and lastly concluding what artwork they like best and why. I found that the majority of students do want an art class offered at their schools, and all but one participant was more than willing to share their story about their narrative painting. Common themes amongst their paintings were family, a specific memory or event, or their present and future lives. I found similar subject matter in their paintings such as animals, houses or huts, and people. My research also unveiled a large difference in the refugee students' paintings as opposed to the other United States participants. The findings also suggest that participants judged other work based on meaning more so than aesthetics. This study explores, in detail, the narrative art and experiences of a very diverse group of students.

Description
This case study explores similarities and differences between the instructors' beliefs about oral corrective feedback and their actual practices in a summer Chinese program. This kind of feedback is beneficial for beginning college-level learners of Chinese to improve their speaking accuracy. The researcher conducted face-to-face interviews with two teachers of Chinese, focusing on their beliefs about oral corrective feedback in their language classrooms. In addition, the researcher recorded teacher-student interactions through class observation in order to analyze the teachers' actual practices of oral corrective feedback. The main findings show that the teachers hold similar beliefs on oral corrective feedback and its beneficial role in helping improve learners speaking accuracy. The fact is that they frequently provide oral corrective feedback in classroom, mostly using recasts. Implications are discussed in view of the necessity of using explicit feedback and recasts appropriately. In addition, this study demonstrates the need for specific professional development and teacher training about how to provide efficient corrective feedback.

Description
A right to the city is a human right that is overlooked in American cities. Cities reflect humanity in collective form, but are manipulated by the powerful at the expense of the powerless. Landscapes of cities tell the city's stories, as historical inequalities become imprinted on the city's physical and symbolic landscapes. In Detroit, Michigan, over forty square miles of the city are vacant, unemployment might be as high as fifty percent, and the city has lost about sixty percent of its population since the mid-1950s. Detroit must now solve its spatial problems in the context of depopulation; the city's planners, nonprofits, and scholars are now debating "planned shrinking" or "right-sizing." Simultaneously, a blooming arts scene is also slowly revitalizing parts of the city. This thesis will critically examine the possibilities of planned shrinking and the arts movement in Detroit, as well as suggest theoretical explanations for the city's dilemmas. Detroit has been the subject of a myopic popular narrative, one that isolates the city from modern America rather than critically examines its place in modern America. Redefining regional healing through honest discourse and developing a more appropriate narrative for Detroit are among the solutions proposed. Finally, the importance of establishing a human right for the city is discussed.

Description
The life of Jean-Michel Basquiat is often misinterpreted in artistic discourse. From a social justice perspective, Basquiat's work is not merely art. Despite the symbolism and subject matter open for analysis, Basquiat articulated the self in relation to nuances of race, socio-economy, and historical scripts based upon real relations and conditions. Of the genre of Neo-Expressionism without a disciplined schooling in art, Jean-Michel is categorized as 'primitive' in style and form, labeled the "first black artist." Beyond the art world's possessive confines and according to post-colonial aesthetics, Jean-Michel articulates the existence of a learning self. With a pedagogical lens, a process of becoming an "artist" deepened Basquiat's expressions of self in relation to a “white” art world, which typically restricted the artist to specific categories and definitional parameters.
While recognition of the "artist" highlights the limitations of 'public' and 'self' in pedagogy, learning of the self through Neo-Expressionism is contingent upon articulating a situated existence among particular "publics," with regard to time and place. Variable dimensions of recognition create a fragmented self with transitional 'stages' and a series of acute shifts re-establish the definitional boundaries of art, definers, and ultimately the self and “Other”. These shifts continuously create new margins of the avant-garde and the self is redefined by art and discourse to sustain capital inflow, thereby replicating the colonial nature of capitalism with regard to communication, material and discovery, and “Other”. The process eschews a realized finality while expression as a relational communication of the situated persona redefines one's identity and demarcates a value of the self.
