Over 35% of multiracial college students fail to earn a degree, which can have significant economic and health costs over their lifespan. This study aimed to better understand college and psychological adjustment among multiracial college students of Hispanic/Latinx and White non-Hispanic descent by examining students’ racial identities and use of resilience resources. Latent profiles of identity were identified to better understand how different aspects of racial identity are clustered in this population. Multiracial college students (N=221) reported on racial identity as measured on multiple dimensions: Hispanic/Latinx identity, Hispanic/Latinx cultural orientation, White identity, identity integration, shifting expressions of identity, and identity …

Chronic diseases, such as diabetes, heart disease, and cancer are leading causes of death in the United States. Although they result from a host of personal and environmental factors, diet remains a critical way to reduce the risk. Plant-based diets in particular are associated with reduction in risk for chronic disease due to an intake that closely mirrors the Dietary Guidelines for fruit and vegetable consumption, fiber, and fat intake. Additionally, plant-based diets offer a sustainable alternative in relation to food production as they often require fewer natural resources overall. While there are many benefits to following a plant-based diet, …

Traditional autonomy within clinical supervision was reinterpreted by incorporating culturally-encompassing autonomy types (individuating and relating autonomy) from the dual autonomy scale. The relations of vertical collectivism and autonomy measures were examined. Lastly, potential moderating effects of vertical collectivism on experience level and autonomy were assessed. The sample consisted of 404 counseling trainees enrolled in graduate programs across the US, aged between 21 and 68. Results from the confirmatory factor analysis supported the proposed two-factor structure of individuating and relating autonomy among counseling trainees for the adapted dual autonomy scale. Results indicated that individuating autonomy was moderately correlated with relating and …

There were two primary goals of this study, the first of which was to replicate previously established curvilinear associations between school affluence and substance use, while assessing potential relations between socioeconomic status (SES) and academic success during the transition to college. The second goal of this study was to establish patterns of perceived parenting factors in order to assess predictive value of such latent profiles with respect to student outcomes relevant to wellbeing and retention in college. Results indicated that substance use was, in fact, associated in a “U-shaped,” curvilinear fashion with high school affluence. Additionally, students grouped into three …

Vision processing on traditional architectures is inefficient due to energy-expensive off-chip data movements. Many researchers advocate pushing processing close to the sensor to substantially reduce data movements. However, continuous near-sensor processing raises the sensor temperature, impairing the fidelity of imaging/vision tasks. The work characterizes the thermal implications of using 3D stacked image sensors with near-sensor vision processing units. The characterization reveals that near-sensor processing reduces system power but degrades image quality. For reasonable image fidelity, the sensor temperature needs to stay below a threshold, situationally determined by application needs. Fortunately, the characterization also identifies opportunities -- unique to the needs …

Migrations, past and present, fundamentally influence human interaction, community building, and social evolution. Studies of contemporary migrations demonstrate that the form and intensity of interaction migrants maintain between homeland and host communities shape social dynamics, innovations, and identities. This dissertation applies a contemporary theoretical framework and biogeochemical analyses to elucidate the scale, processes, and impacts of migration in the hinterland of the pre-Hispanic Tiwanaku polity (ca. AD 500-1100). Social diversity is examined by reconstructing the migration histories and dietary choices of individuals interred at the Tiwanaku-affiliated site of Omo M10 in the Moquegua Valley of southern Peru.

理性决策理论基于“完全理性”假定,追求帕累托最优即个体的利益最大化。但是实际决策过程中,人的行为具备“有意识的理性,但这种理性又是有限的”,投资者也是并不是完全理性、同质的。海外投资也是如此,其背景特征诸如地域、性格、年龄、财富等特征都会对海外投资决策产生重大的影响,其程度大小势必也会因投资者背景特征的差异有所不同。考虑到投资者风险偏好与海外投资活动的关系鲜有文献涉及,笔者愿意做“第一个吃螃蟹的人”,选取该视角展开论述。 本文首先对前人的研究进行总结,概述了风险偏好的理论和偏好水平的度量办法,并总结了风险偏好对海外投资影响的理论基础,即决策理论和有限理性与行为经济学理论,为本文的研究奠定了坚实的理论基础。 其次,开展了问卷调查,对小城市城镇人群、二三线大城市人群、一线大城市人群、海外华人群体等不同地域的25-60岁之间的人群作为调查对象,回收了有效问卷3748份,并就问卷结果进行了描述性分析。发现跨地域人群有着不同的投资需求,小城市城镇人群整体来说对于海外投资需求较低;二三线大城市人群对海外投资不抗拒且具备一定研究和分析能力;一线大城市人群26%已考虑移民或大量海外投资,对海外投资产品有很强的分析能力;海外华人群体38%已考虑移民或大量海外投资,对于各类海外投资产品的接触机会很多。 再次,本文对风险偏好水平进行综合评价和度量。在此基础上,设定了研究变量和研究模型,采用回归分析的方法,对跨地域人群风险偏好、跨地域人群风险偏好对海外投资影响两块进行了实证分析,并验证了相关假设。本文认为,跨地域人群具有较为明显的风险偏好,其中一线城市人群风险偏好最高,高于海外华人群体,高于二三线大城市人群和小城市城镇人群。基于教育水平、财富程度和信息获取的风险偏好对海外投资影响的实证分析结果显示,风险偏好越高的区域,海外投资总额越多。充分验证了跨地域人群不同的风险偏好,以及风险偏好对海外投资的显著正向影响关系。最后,本文针对实证结果提出了相应的对策建议。 Dissertation/Thesis

中医药是中华文明的瑰宝,中药材是中医药文化和产业的核心。随着近年来国家相关政策出台,中药材产业的发展备受瞩目。由于中药材产业链条长,层级多,各层级间信息不对称,因而中药材市场普遍具有“假”、“乱”、“杂”的问题。 A公司的中药材全产业链服务商模式,通过对上游各主要专营商的整合,形成一定的平台综合集采能力,并开始得到下游医药厂家、药店认可,在市场逐步形成品牌号召力。本文实证研究A公司商业模式的转型对中药材市场价格的影响,进而分析中药材全产业链服务商模式在中药材行业健康发展中所发挥的积极作用。研究结果表明,上下游产销结合的中药材全产业链服务商模式,只有在形成一定收购规模,对市场价格产生一定影响的时候,才能充分释放药材质量的信号,润滑药材交易市场,提高收购价格,增加市场波动率,发挥价格发现作用。由于中药材市场的信息不对称程度较高,如果产销结合模式仍处于初级开创阶段,产销结合模式释放的药材质量信号则不足以全面改善信息不对称的状况。 Dissertation/Thesis

As automation becomes more prevalent in society, the frequency that systems involve interactive human-automation control increases. Previous studies have shown accountability to be a valuable way of eliciting human engagement and reducing various biases, but these studies have involved the presence of an authority figure during the research. The current research sought to explore the effect of accountability in the absence of an authority figure. To do this, 40 participants took part in this study by playing a microworld simulation. Half were told they would be interviewed after the simulation, and half were told data was not being collected. Eleven …

近些年来,我国城市化进程不断加快,到2020年我国常住人口城镇化率将达到60%左右,户籍人口城镇化率将会达到45%左右。伴随着我国城市化进程的高速推进以及经济水平的不断提高,公共物品及服务的需求程度加大,政府单独出资建设公共项目会导致资金不足、经营管理效率低下等问题。与此同时,我国当前不同层级地方政府的政府性债务都达到了一个非常高的水平,截至2017年末,中国地方政府债务16.47万亿元,债务率(债务余额/综合财力)为76.5%,其中地方负有偿还责任的债务约12.9万亿,地方政府性债务的控制和转化成为经济新常态下重要特征之一。在地方债务压力较大的情况下,PPP将替代土地财政和地方政府融资,为我国新型城镇化建设提供可持续的资金支持,PPP模式成为当前城市建设领域融资的重要选项。 据此,本文基于实证研究方法探讨在债务约束的背景下,在地方政府债务约束下,PPP模式的引入,对城市规划中建设用地面积、人口规划规模与容量、建设用地属性等的城市规划变量的影响;与此同时,考虑到地方政府的政策很大程度上受到是由地方官员,特别是受到作为地方政府党政“一把手”的市委书记和市长的晋升压力和激励的影响,讨论市委书记/市长的晋升压力和激励对PPP模式引入效果的影响。研究发现,在地方政府债务约束下,PPP模式的引入,显著增加城市规划中建设用地面积、人口规划规模与容量、建设用地属性等的城市规划变量;同时,地方政府官员存在利用PPP放大城市建设和规划规模的行为,反映了PPP项目在引入和使用的过程中很大程度上受政府官员的激励的影响。 Dissertation/Thesis

本文采用2010年1月1日至2017年12月31日在香港主板IPO上市的共574家公司作为研究样本,系统采集包括与发行人、承销商、投资人、发行热度、市场每日交易数据等相关的数据近100项,对超额配售选择权在香港IPO中的实际效用进行实证研究,研究发现:1)超额配售选择的确可以起到提高发行价格,降低IPO抑价率的作用,但是同时也是破发的主要原因。2)由超额配售选择权赋予承销商稳价行为中,市场买入量越大,最大回撤越大,市场下跌风险越大同时超额配售选择权还导致了最大回撤日的推后,增大了稳价结束后的市场风险,而这很有可能是由于承销商追求更高利益造成的。3)没有证据显示,超额配售选择权会降低承销商的佣金比例,但是,超额配售选择权却为承销商带来非常高的额外收益,而这个收益与市场下跌幅度和承销商从市场购买股份的比例直接相关。 其中,本文首次对最大回撤率、最大回撤日与承销商市场买入量之间的关系进行实证研究,揭示了承销商市场买入量与承销商收益正相关,与最大回撤率负相关,与最大回撤日正相关的关系,可能是增加市场下跌风险的因素。这与现有理论中及监管机构的预期中,“超额配售选择权具有向上稳定价格的作用”是有一定偏差的。 根据研究结果,本文首先建议发行人要客观对待超额配售选择权提升发行价格的作用,以免引起破发。其次建议市场投资人要客观认识超额配售选择权的作用,不要由于超额配售选择权的存在给与发行过高的认同价格。再次建议发行人要能够认识到超额配售选择权是承销商零成本获得的一个有固定收益保障的看空期权,是承销商在承销IPO时的收益之一,而股价下跌幅度与承销商的收益正相关。因此要对承销商的稳价行为进行一定管控,同时可以因为超额配售选择权的存在而要求更低的承销佣金比例。最后建议承销商要维护市场公平,爱护自己的声誉,尽可能避免因超额配售选择权的使用对市场造成不应有的干扰。 Dissertation/Thesis

Background: The Academy of Nutrition and Dietetics states that it is possible for a vegetarian to obtain the recommended amount of nutrients with a properly planned diet but nutrient deficiencies, such as vitamin B12 deficiency, may occur if diet planning is not optimal. An early indicator of B12 deficiency is raised homocysteine concentrations in blood which can cause health issues. Objective: The amino acid methionine is consumed via dietary protein. Methionine is used in the biosynthesis of other proteins. After a removal of a methyl group, it makes homocysteine. Slightly raised homocysteine may promote greater synthesis of glutathione, an important …

While a clean energy infrastructure is growing, mid-term strategies that are compatible with the current infrastructure should be developed. Carbon capture and storage in fossil-fuel power plants is one way to avoid our current gigaton-scale emission of carbon dioxide into the atmosphere. However, for this to be possible, separation techniques are necessary to remove the nitrogen from air before combustion or from the flue gas after combustion.

A continuously and stably stratified fluid contained in a square cavity subjected to harmonic body forcing is studied numerically by solving the Navier-Stokes equations under the Boussinesq approximation. Complex dynamics are observed near the onset of instability of the basic state, which is a flow configuration that is always an exact analytical solution of the governing equations. The instability of the basic state to perturbations is first studied with linear stability analysis (Floquet analysis), revealing a multitude of intersecting synchronous and subharmonic resonance tongues in parameter space. A modal reduction method for determining the locus of basic state instability is …

Medical policies, practices, and definitions do not exist solely in the clinical realm; they show up in the lived experiences of patients. This research examines how people with the chronic illness called myalgic encephalomyelitis (ME) define their own illness experiences. They have situated knowledge about their illness onset, search for care, and clinical encounters. Their knowledge complicates and challenges the existing norms in clinical practice and medical discourse, as the experience of searching for care with ME reveals weaknesses in a system that is focused on acute care. Patient narratives reveal institutional patterns that obstruct access to medical care, such …

By focusing on photojournalists for LIFE and Ladies’ Home Journal, I investigate mental health care in state institutions located in America during the Great Depression and World War II immediately prior to the great deinstitutionalization that began in the 1950s. Relying upon scholars of medical humanities, social theory, disability studies, feminist studies, the history of psychiatry, and the history of art, I consider the iconography used to represent mental illness in photography during the first half of the twentieth century to explore the ways mentally ill individuals were presented as disordered and lacking humanity. I explore the didactic nature of …

Existing theories suggest that evidence is accumulated before making a decision with competing goals. In motor tasks, reward and motor costs have been shown to influence the decision, but the interaction between these two variables has not been studied in depth. A novel reward-based sensorimotor decision-making task was developed to investigate how reward and motor costs interact to influence decisions. In human subjects, two targets of varying size and reward were presented. After a series of three tones, subjects initiated a movement as one of the targets disappeared. Reward was awarded when participants reached through the remaining target within a …

The present series of studies examined whether a novel implementation of an intermittent restraint (IR) chronic stress paradigm could be used to investigate hippocampal-dependent spatial ability in both sexes. In experiments 1 and 2, Sprague- Dawley male rats were used to identify the optimal IR parameters to assess spatial ability. For IR, rats were restrained for 2 or 6hrs/day (IR2, IR6, respectively) for five days and then given two days off, a process that was repeated for three weeks and compared to rats restrained for 6hrs/d for each day (DR6) and non-stressed controls (CON). Spatial memory was tested on the …

Rapid intraoperative diagnosis of brain tumors is of great importance for planning treatment and guiding the surgeon about the extent of resection. Currently, the standard for the preliminary intraoperative tissue analysis is frozen section biopsy that has major limitations such as tissue freezing and cutting artifacts, sampling errors, lack of immediate interaction between the pathologist and the surgeon, and time consuming. Handheld, portable confocal laser endomicroscopy (CLE) is being explored in neurosurgery for its ability to image histopathological features of tissue at cellular resolution in real time during brain tumor surgery. Over the course of examination of the surgical tumor …

Oxygen fugacity (ƒO2) is a thermodynamic variable used to represent the redox state of a material or a system. It is equivalent to the partial pressure of oxygen in a particular environment corrected for the non-ideal behavior of the gas. ƒO2 is often used to indicate the potential for iron to occur in a more oxidized or reduced state at a particular temperature and pressure in a natural system. Secondary ion mass spectrometry (SIMS) is a powerful analytical instrument that can be used to analyze elemental and isotopic compositional information about microscopic features within solid materials. SIMS analyses of the …

DNA and RNA are generally regarded as one of the central molecules in molecular biology. Recent advancements in the field of DNA/RNA nanotechnology witnessed the success of usage of DNA/RNA as programmable molecules to construct nano-objects with predefined shapes and dynamic molecular machines for various functions. From the perspective of structural design with nucleic acid, there are basically two types of assembly method, DNA tile based assembly and DNA origami based assembly, used to construct infinite-sized crystal structures and finite-sized molecular structures. The assembled structure can be used for arrangement of other molecules or nanoparticles with the resolution of nanometers …

Mitochondria are energy-producing organelles present in eukaryotic cells. Energy as adenosine triphosphate (ATP) is produced at the end of a series of electron transfers called the electron transport chain (ETC). Such a highly coordinated and regulated series of electron transfer reactions give rise to a small percentage of electron leakage which, by the subsequent reduction of molecular oxygen, produce superoxide anions (O2.-). These anions initiate the production of additional highly reactive oxygen-containing radicals commonly known as reactive oxygen species (ROS). Although cells are equipped with endogenous antioxidant systems to minimize ROS accumulation, these endogenous defense systems become inadequate when ROS …

The concept of distribution is one of the core ideas of probability theory and inferential statistics, if not the core idea. Many introductory statistics textbooks pay lip service to stochastic/random processes but how do students think about these processes? This study sought to explore what understandings of stochastic process students develop as they work through materials intended to support them in constructing the long-run behavior meaning for distribution. I collected data in three phases. First, I conducted a set of task-based clinical interviews that allowed me to build initial models for the students’ meanings for randomness and probability. Second, I …

The purpose of this action research was to understand how reflective, job-embedded early childhood science professional learning and development (PLD) impacted Early Head Start (EHS) teacher learning and their perceptions toward science with toddlers. Limited content knowledge and lack of formal preparation impact teachers’ understanding of developmentally appropriate science and their capacity to support children to develop science skills. In Arizona, limited availability of early childhood science coursework and no science-related PLD for toddler teachers showed the need for this project. Four literature themes were reviewed: teacher as researcher, how people learn, reflective PLD, and how young children develop scientific …

Light Emerging is a symphonic dance suite in five movements. The work’s approximate length is 25 minutes; it is scored for flute, oboe, clarinet in Bb, bassoon, horn in F, trumpet in C with loop pedal, trombone, percussion, electronic percussion, piano, strings, and fixed media. Each movement of the dance suite is written to be performed as a standalone piece or together as one multimovement work. The music showcases open quintal sonorities layered in conflicting substructures, which contract into denser brooding passages and transform into tonal fanfares. Attempting to capture the essence of how humanity uniquely experiences light and assigns …

This thesis examines perceptions of climate change in literature through the lens of the environmental humanities, an interdisciplinary field that brings history, ecocriticism, and anthropology together to consider the environmental past, present and future. The project began in Iceland, during the Svartárkot Culture-Nature Program called “Human Ecology and Culture at Lake Mývatn 1700-2000: Dimensions of Environmental and Cultural Change”. Over the course of 10 days, director of the program, Viðar Hreinsson, an acclaimed literary and Icelandic Saga scholar, brought in researchers from different fields of study in Iceland to give students a holistically academic approach to their own environmental research. …

Biological soil crusts (biocrusts) are topsoil communities of organisms that contribute to soil fertility and erosion resistance in drylands. Anthropogenic disturbances can quickly damage these communities and their natural recovery can take decades. With the development of accelerated restoration strategies in mind, I studied physiological mechanisms controlling the establishment of cyanobacteria in biocrusts, since these photoautotrophs are not just the biocrust pioneer organisms, but also largely responsible for improving key soil attributes such as physical stability, nutrient content, water retention and albedo. I started by determining the cyanobacterial community composition of a variety of biocrust types from deserts in the …

The study of genre literature in general, and fantasy or fairy tale literature in particular, by its very nature, falls outside the normal course of literary theory. This paper evaluates various approaches taken to create a framework within which scholarly research and evaluation of these types of genre literature might occur. This is done applying Secondary World theory to better-established literary foci, such as psychological analysis and monster theory while still respecting the premises posited in traditional literary inquiry.

This research investigates the biophysical and institutional mechanisms affecting the distribution of metals in the Sonoran Desert of Arizona. To date, a long-term, interdisciplinary perspective on metal pollution in the region has been lacking. To address this gap, I integrated approaches from environmental chemistry, historical geography, and institutional economics to study the history of metal pollution in the desert. First, by analyzing the chemistry embodied in the sequentially-grown spines of long-lived cacti, I created a record of metal pollution that details biogeochemical trends in the desert since the 1980s. These data suggest that metal pollution is not simply a legacy …
