Description
"Culture talk" figures prominently in the discussions of and about Muslims, both locally and globally. Culture, in these discussions, is considered to be the underlying cause of gender and generational divides giving rise to an alleged "identity crisis." Culture also presumably conceals and contaminates "pure/true Islam." Culture serves as the scaffold on which all that divides Muslim American immigrants and converts is built; furthermore, the fear of a Muslim cultural takeover underpins the "Islamization of America" narrative. This dissertation engages these generational and "immigrant"-"indigenous" fissures and the current narratives that dominate Muslim and public spheres. It does so through the perspectives of the offspring of converts and immigrants. As the children and grandchildren of immigrants and converts come of age, and distant as they are from historical processes and experiences that shaped the parents' generations while having shared a socialization process as both Muslim and American, what role do they play in the current chapter of Islam in post-9/11 America? Will the younger generation be able to cross the divides, mend the fissures, and play a pivotal role in an "American Muslim community"? Examining how younger generations of both backgrounds view each other and their respective roles in forging an American Muslim belonging, agenda and discourse is a timely and much needed inquiry. This project aims to contribute by shedding more light on the identities, perspectives and roles of these younger generations through the four dominant narratives of identity crisis, pure/true Islam vs. Cultural Islam, the Islamization of America, and creation of an American Muslim community/identity/culture. These narratives are both part of public discourse and themes generated from interviews, a questionnaire\survey, and personal observation. This ethnographic study examines how American born and/or raised offspring of both converts to Islam and immigrant Muslims in the Phoenix and Chicago metropolitan areas define self and community, how they negotiate fissures and fault lines (ethnicity, race, class, gender, and religious interpretation) within their communities, and how their faith informs daily life and envisions a future. I utilize participant observation, interviews, and surveys and examine digital, visual and published media to answer these questions.

Description
Food system and health characteristics were evaluated across the last Waorani hunter-gatherer group in Amazonian Ecuador and a remote neighboring Kichwa indigenous subsistence agriculture community. Hunter-gatherer food systems like the Waorani foragers may not only be nutritionally, but also pharmaceutically beneficial because of high dietary intake of varied plant phytochemical compounds. A modern diet that reduces these dietary plant defense phytochemicals below levels typical in human evolutionary history may leave humans vulnerable to diseases that were controlled through a foraging diet. Few studies consider the health impact of the recent drastic reduction of plant phytochemical content in the modern global food system, which has eliminated essential components of food because they are not considered "nutrients". The antimicrobial and anti-inflammatory nature of the food system may not only regulate infectious pathogens and inflammatory disease, but also support beneficial microbes in human hosts, reducing vulnerability to chronic diseases. Waorani foragers seem immune to certain infections with very low rates of chronic disease. Does returning to certain characteristics of a foraging food system begin to restore the human body microbe balance and inflammatory response to evolutionary norms, and if so, what implication does this have for the treatment of disease? Several years of data on dietary and health differences across the foragers and the farmers was gathered. There were major differences in health outcomes across the board. In the Waorani forager group there were no signs of infection in serious wounds such as 3rd degree burns and spear wounds. The foragers had one-degree lower body temperature than the farmers. The Waorani had an absence of signs of chronic diseases including vision and blood pressure that did not change markedly with age while Kichwa farmers suffered from both chronic diseases and physiological indicators of aging. In the Waorani forager population, there was an absence of many common regional infectious diseases, from helminthes to staphylococcus. Study design helped control for confounders (exercise, environment, genetic factors, non-phytochemical dietary intake). This study provides evidence of the major role total phytochemical dietary intake plays in human health, often not considered by policymakers and nutritional and agricultural scientists.

Description
This dissertation examines incidents of conflict and violence amid communities of the Maya Tzotzil Chamula in Chiapas, Mexico. Despite ostensible homogeneity, or more social and cultural resemblances than differences, conflicts arise between many Chamula because of how they acquire desire according to others who mediate what is desirable. These conflicts relate well to Rene Girard's hypothesis that mimetic desire influences identity yet generates conflict as imitation fosters rivalry. Qualitative methods of participant observation, interviews, and document research depict how desire, identity, and conflict interrelate. Ethnographic cases show how conflict emerges "interdividually" as rivals compete to obtain objects imputed desirable. The study begins with how young Tzotzils today appropriate the desires of others, becoming lawyer, spiritual guide, rock and roll singer, or anthropologist. Complex examples exhibit groups struggling for power and privilege within or between members of communities as they vie over "objects of desire" such as status, land, water, or representations of power and pecuniary interests. For some Chamula, mimetic rivalry works to deny resemblances with others despite being alike as neighbor, relative, farmer, carpenter, or member of the same political or religious affiliation. The study also highlights mimetic interactions that have shaped Maya struggles in the past, such as the uprisings of 1712, 1867, and 1911. Interpretive analysis explores how identity formation (structures), imitative desire (motivated interaction), and practice (habitual agency) together galvanize material and psychosocial variables for conflict. Imitative desire is worth observing because of its long-term implications for human adaptation and social change. As a contribution to social conflict theory, this dissertation offers a critical perspective to current research on mimetic desire as a significant force in human relations.

Description
In this thesis, we present the study of several physical properties of relativistic mat- ters under extreme conditions. We start by deriving the rate of the nonleptonic weak processes and the bulk viscosity in several spin-one color superconducting phases of quark matter. We also calculate the bulk viscosity in the nonlinear and anharmonic regime in the normal phase of strange quark matter. We point out several qualitative effects due to the anharmonicity, although quantitatively they appear to be relatively small. In the corresponding study, we take into account the interplay between the non- leptonic and semileptonic weak processes. The results can be important in order to relate accessible observables of compact stars to their internal composition. We also use quantum field theoretical methods to study the transport properties in monolayer graphene in a strong magnetic field. The corresponding quasi-relativistic system re- veals an anomalous quantum Hall effect, whose features are directly connected with the spontaneous flavor symmetry breaking. We study the microscopic origin of Fara- day rotation and magneto-optical transmission in graphene and show that their main features are in agreement with the experimental data.

Description
The children of immigrants who arrived in the United States in the 1980s now make up one of the fastest growing components of American society. They face unique and interesting pressures as they incorporate aspects of their parents' heritage into their contemporary American lives. The purpose of this dissertation is to offer an in-depth look at the 1.5 and second generation by examining how the immigrant descendants negotiate assimilative pressures, transnational practices, and ethnic identification. Using ethnographic research methods, such as participant observation and in-depth interviews, I researched the children of immigrants, ages 18-30, living in northwest Arkansas, who have at least one immigrant parent from Latin America. This research is important because non-traditional receiving towns, especially more rural localities, are often overlooked by scholarly studies of migration in favor of larger metropolitan centers (e.g., Los Angeles, Chicago). Studying immigrant descendants in smaller towns that are becoming increasingly populated by Hispanic/Latinos will create a better understanding of how a new generation of immigrants is assimilating into American society and culture. To increase awareness on the Hispanic/Latino 1.5 and second generation living in small town America and to offer potential solutions to facilitate an upwardly mobile future for this population, my dissertation explores a number of research questions. First, how is this population assimilating to the U.S.? Second, are members of the 1.5 and second generation transnational? How active is this transnational lifestyle? Will transnationalism persist as they grow older? Third, how does this population identify themselves ethnically? I also pay particular attention to the relationships among assimilation, transnationalism, and ethnic identity. My dissertation documents the lived experiences of the 1.5 and second generation in northwest Arkansas. The children of immigrants are one of the fastest growing groups nationwide. To understand their world and the lives they lead is to understand the new fabric of American society. I anticipate that the results from this research can be used to facilitate easier transitions to the U.S. among current and prospective immigrant generations, ensuring a brighter outlook for the future of the newest members of U.S. society.

Description
Numerical simulations are very helpful in understanding the physics of the formation of structure and galaxies. However, it is sometimes difficult to interpret model data with respect to observations, partly due to the difficulties and background noise inherent to observation. The goal, here, is to attempt to bridge this gap between simulation and observation by rendering the model output in image format which is then processed by tools commonly used in observational astronomy. Images are synthesized in various filters by folding the output of cosmological simulations of gasdynamics with star-formation and dark matter with the Bruzual- Charlot stellar population synthesis models. A variation of the Virgo-Gadget numerical simulation code is used with the hybrid gas and stellar formation models of Springel and Hernquist (2003). Outputs taken at various redshifts are stacked to create a synthetic view of the simulated star clusters. Source Extractor (SExtractor) is used to find groupings of stellar populations which are considered as galaxies or galaxy building blocks and photometry used to estimate the rest frame luminosities and distribution functions. With further refinements, this is expected to provide support for missions such as JWST, as well as to probe what additional physics are needed to model the data. The results show good agreement in many respects with observed properties of the galaxy luminosity function (LF) over a wide range of high redshifts. In particular, the slope (alpha) when fitted to the standard Schechter function shows excellent agreement both in value and evolution with redshift, when compared with observation. Discrepancies of other properties with observation are seen to be a result of limitations of the simulation and additional feedback mechanisms which are needed.

Description
Understanding the temperature structure of protoplanetary disks (PPDs) is paramount to modeling disk evolution and future planet formation. PPDs around T Tauri stars have two primary heating sources, protostellar irradiation, which depends on the flaring of the disk, and accretional heating as viscous coupling between annuli dissipate energy. I have written a "1.5-D" radiative transfer code to calculate disk temperatures assuming hydrostatic and radiative equilibrium. The model solves for the temperature at all locations simultaneously using Rybicki's method, converges rapidly at high optical depth, and retains full frequency dependence. The likely cause of accretional heating in PPDs is the magnetorotational instability (MRI), which acts where gas ionization is sufficiently high for gas to couple to the magnetic field. This will occur in surface layers of the disk, leaving the interior portions of the disk inactive ("dead zone"). I calculate temperatures in PPDs undergoing such "layered accretion." Since the accretional heating is concentrated far from the midplane, temperatures in the disk's interior are lower than in PPDs modeled with vertically uniform accretion. The method is used to study for the first time disks evolving via the magnetorotational instability, which operates primarily in surface layers. I find that temperatures in layered accretion disks do not significantly differ from those of "passive disks," where no accretional heating exists. Emergent spectra are insensitive to active layer thickness, making it difficult to observationally identify disks undergoing layered vs. uniform accretion. I also calculate the ionization chemistry in PPDs, using an ionization network including multiple charge states of dust grains. Combined with a criterion for the onset of the MRI, I calculate where the MRI can be initiated and the extent of dead zones in PPDs. After accounting for feedback between temperature and active layer thickness, I find the surface density of the actively accreting layers falls rapidly with distance from the protostar, leading to a net outward flow of mass from ~0.1 to 3 AU. The clearing out of the innermost zones is possibly consistent with the observed behavior of recently discovered "transition disks."

Description
The dissertation is based on 15 months of ethnographically-informed qualitative research at a liberal arts college in the Himalayan nation of Bhutan. It seeks to provide a sense of daily life and experience of schooling in general and for female students in particular. Access to literacy and the opportunities that formal education can provide are comparatively recent for most Bhutanese women. This dissertation will look at how state-sponsored schooling has shaped gender relations and experiences in Bhutan where non-monastic, co-educational institutions were unknown before the 1960s. While Bhutanese women continue to be under-represented in politics, upper level government positions and public life in general, it is frequently claimed at a variety of different levels (for instance in local media and government reports), that Bhutan, unlike it South Asian neighbors, has a high degree of gender equity. It is argued that any under-representation does not reflect access or opportunity but is instead the result of women's decision not to "come up" and participate. However this dissertation will dispute the claim that female students could choose to be more visible, vocal and mobile in classrooms and on campus without being challenged or discouraged. I will show that school is a gendered context, in which female students are consistently reminded of their "limitations" and their "appropriate place" through the use of familiar social practices such as teasing, gossip, and harassment. Schooling, particularly in developing nations like Bhutan, is usually implicitly and uncritically understood to be a neutral resource, often evaluated in relation to development aims such as creating a more educated and skilled workforce. While Bhutanese schools do seem to promote new kind of opportunity and new understandings of success, they also continue to recognize, maintain and reproduce conventional values around hierarchy, knowledge transmission, cooperation (or group identity) and gender norms. This dissertation will also show how emergent disparities in wealth and opportunity in the nation at large are beginning to be reflected and reproduced in both the experience of schooling and the job market in ways that Bhutanese development policy is not yet able to adequately address.

Description
This thesis deals with the first measurements done with a cold neutron beam at the Spallation Neutron Source at Oak Ridge National Laboratory. The experimental technique consisted of capturing polarized cold neutrons by nuclei to measure parity-violation in the angular distribution of the gamma rays following neutron capture. The measurements presented here for the nuclei Chlorine ( 35Cl) and Aluminum ( 27Al ) are part of a program with the ultimate goal of measuring the asymmetry in the angular distribution of gamma rays emitted in the capture of neutrons on protons, with a precision better than 10-8, in order to extract the weak hadronic coupling constant due to pion exchange interaction with isospin change equal with one ( hπ 1). Based on theoretical calculations asymmetry in the angular distribution of the gamma rays from neutron capture on protons has an estimated size of 5·10-8. This implies that the Al parity violation asymmetry and its uncertainty have to be known with a precision smaller than 4·10-8. The proton target is liquid Hydrogen (H2) contained in an Aluminum vessel. Results are presented for parity violation and parity-conserving asymmetries in Chlorine and Aluminum. The systematic and statistical uncertainties in the calculation of the parity-violating and parity-conserving asymmetries are discussed.

Description
This dissertation is intended to tie together a body of work which utilizes a variety of methods to study applied mathematical models involving heterogeneity often omitted with classical modeling techniques. I posit three cogent classifications of heterogeneity: physiological, behavioral, and local (specifically connectivity in this work). I consider physiological heterogeneity using the method of transport equations to study heterogeneous susceptibility to diseases in open populations (those with births and deaths). I then present three separate models of behavioral heterogeneity. An SIS/SAS model of gonorrhea transmission in a population of highly active men-who-have-sex-with-men (MSM) is presented to study the impact of safe behavior (prevention and self-awareness) on the prevalence of this endemic disease. Behavior is modeled in this examples via static parameters describing consistent condom use and frequency of STD testing. In an example of behavioral heterogeneity, in the absence of underlying dynamics, I present a generalization to ``test theory without an answer key" (also known as cultural consensus modeling or CCM). CCM is commonly used to study the distribution of cultural knowledge within a population. The generalized framework presented allows for selecting the best model among various extensions of CCM: multiple subcultures, estimating the degree to which individuals guess yes, and making competence homogenous in the population. This permits model selection based on the principle of information criteria. The third behaviorally heterogeneous model studies adaptive behavioral response based on epidemiological-economic theory within an $SIR$ epidemic setting. Theorems used to analyze the stability of such models with a generalized, non-linear incidence structure are adapted and applied to the case of standard incidence and adaptive incidence. As an example of study in spatial heterogeneity I provide an explicit solution to a generalization of the continuous time approximation of the Albert-Barabasi scale-free network algorithm. The solution is found by recursively solving the differential equations via integrating factors, identifying a pattern for the coefficients and then proving this observed pattern is consistent using induction. An application to disease dynamics on such evolving structures is then studied.
