Border pedagogy, social reproduction and structures of feeling: Explaining success in a slum school, Apollo School, Nairobi, Kenya
Creators: name: Musilla, Mumbua Sarah
Publisher: name: American University
Year: 2023

description: Slums in Kenya house some of the most disadvantaged populations in terms of schooling and economic marginalization. Apollo, a school which has consistently attained high scores in grade eight centralized examinations for almost three decades, is, however, situated in Nairobi slums. Its continued outstanding performance defies commonplace expectations that low income students cannot excel in academics. This study examines how the school has contested the ideology of failure that is normally associated with schooling in the slums. While my research does not question the importance of facilities in learning, it offers another way of looking at resource-based models in perceptions of successful education. My study establishes that Apollo is a battleground where both the ideologies of failure and success are in contestation. First, it examines the assumptions of what success in education in Kenya means. It assembles the politics of community needs in education and examines Apollo's attempts to respond to them. I find that the assumption that one needs formal schooling in order to get ahead in Kenya is a strong motivating force for the parents, teachers and students. Second, I explore the perceptions of Apollo population about their physical and social location vis-a-vis their chances of achieving success in education. The way the teachers and students interpellate their position in slum ideology promotes strategies that advance the success ideology. Their positive interpellation provides a counternarrative to slum habitation and its associated ideology of failure. Third, my study investigates the underside of the success ideology. The practical process of attaining exemplary performance demands not only charismatic leadership but also unwavering discipline, strong work ethics, somewhat structured pedagogy and relentless commitment from the teachers and students. Fourth, I examine the success ideology in linguistic practice. Language is used by Apollo teachers and students to position themselves as major actors in the creation and maintenance of success and construction of Apollo school as a space where success prevails. Fifth, the study situates the success ideology within broader socio-political and cultural discourses that negotiate inequality. The success ideology is embedded in contested socio-political and economic terrains in education, language and culture.

The role of anti -human trafficking community partnerships in the identification of and response to human trafficking victims in the United States
Creators: name: Small, Kevonne Margaret

Year: 2023

description: Research shows that transnational crimes are increasing in scope and magnitude. One type of transnational crime that is plaguing communities is the complex crime of human trafficking. The United States government is committed to combating this crime both worldwide and within its own borders through the primary vehicle of the Trafficking Victims Protection Act of 2000. The main goals of the TVPA are to prevent human trafficking, prosecute its perpetrators, and to protect its victims. While the TVPA created a mechanism for cooperative federalism on the issue of human trafficking, little is known about how local community partnerships were working to achieve the desired goals of the federal government, or their own local goals. What remains unanswered in the literature is federally funded anti-human trafficking community partnerships an effective tool in the identification of and response to human trafficking victims? An answer to this overall research question is necessary since human trafficking is considered to be an increasing crime problem affecting local communities, and because limited public resources continue to be spent supporting these partnerships. Secondary data analysis was conducted using data from 127 in-depth interviews conducted over three years with partnership members, and with victims of human trafficking. Findings suggest that the use of anti-human trafficking community partnerships can have promising results for identifying victims and responding to their needs.

Adversarial Domain Adaptation with Prototype-Based Normalized Output Conditioner

description: In this work, we attempt to address unsupervised domain adaptation by devising simple and compact conditional domain adversarial training methods. We first revisit the simple concatenation conditioning strategy where features are concatenated with output predictions as the input of the discriminator. We find the concatenation strategy suffers from the weak conditioning strength. We further demonstrate that enlarging the norm of concatenated predictions can effectively energize the conditional domain alignment. Thus we improve concatenation conditioning by normalizing the output predictions to have the same norm of features, and term the derived method as Normalized OutpUt coNditioner~(NOUN). However, conditioning on raw output predictions for domain alignment, NOUN suffers from inaccurate predictions of the target domain. To this end, we propose to condition the cross-domain feature alignment in the prototype space rather than in the output space. Combining the novel prototype-based conditioning with NOUN, we term the enhanced method as PROtotype-based Normalized OutpUt coNditioner~(PRONOUN). Experiments on both object recognition and semantic segmentation show that NOUN can effectively align the multi-modal structures across domains and even outperform state-of-the-art domain adversarial training methods. Together with prototype-based conditioning, PRONOUN further improves the adaptation performance over NOUN on multiple object recognition benchmarks for UDA.

description: Solutions to the four-dimensional Euclidean Weyl equation in the background of a general JNR N-instanton are known to be normalisable and regular throughout four-space. We show that these solutions are asymptotically given by a linear combination of simple singular solutions to the free Weyl equation, which can be interpreted as localised spinors. The `spinorial' data parameterising the asymptotics of the delocalised solutions to the Weyl equation in the presence of the instanton almost determines the background instanton, yet not completely. However, it captures the geometry and symmetry of the underlying instanton configuration.

description: When I began writing I wanted to tell a story. The story is about Columbia Heights, a neighborhood in NW Washington. I believe this is an important story to tell because it springs from a concern with the human condition generally and with the condition of children in the inner city specifically. Simply put this dissertation is about three things: Power, Place and History. In terms of gentrification in Columbia Heights it is about the power of the insurance and real estate industries, developers and banks to make decisions which directly affect all of our lives and life chances. It is also about our power as human beings both individually and collectively to gain knowledge and understanding of how these institutions operate and our power to oppose them when they prioritize the accumulation of wealth ahead of human lives. Second, it is about place. In general terms I am discussing Columbia Heights and the way gentrification is changing the neighborhood day by day. More specifically my dissertation is about grassroots organizing that I participated in with a group of concerned mothers who wanted to stop The Greater Washington Boys and Girls club from selling clubhouse #10 on 14th street. Not only do these mothers have children who use the club everyday in a neighborhood with precious little recreation space. Many of these same mothers went to the club when they were children and it is a part of each of their personal histories. Oftentimes in the inner-city we live in communities of fate where we are intimately connected to our neighbors and vice versa because we all lack the material wealth to make it far on our own. We develop ties to specific places (such as the Boys and Girls club on 14th Street) because they embody our collective history. When these places are threatened we rally around them.

description: The accidental degeneracy of various ground states in a fully frustrated XY model with a honeycomb lattice is shown to survive even when the free energy of the harmonic fluctuations is taken into account. The reason for that consists in the existence of a hidden gauge symmetry between the Hamiltonians describing the harmonic fluctuations in all these ground states. A particular vortex pattern is selected only when anharmonic fluctuations are taken into account. However, the observation of vortex ordering requires relatively large system size L>>100000.

description: We study the collective behaviour of an ensemble of coupled motile elements whose interactions depend on time and are alternatively attractive or repulsive. The evolution of interactions is driven by individual internal variables with autonomous dynamics. The system exhibits different dynamical regimes, with various forms of collective organization, controlled by the range of interactions and the dispersion of time scales in the evolution of the internal variables. In the limit of large interaction ranges, it reduces to an ensemble of coupled identical phase oscillators and, to some extent, admits to be treated analytically. We find and characterize a transition between ordered and disordered states, mediated by a regime of dynamical clustering.

description: The results of micro-structural and detailed magnetization studies are reported here for our recently published TbSr2Cu2.7Mo0.3O7+d superconductor with a transition temperature (Tc) at as high as 80 K [1]. From XRD and EDX the sample was confirmed to be of single-phase and possess the nominal cation stoichiometry. The SEM images showed well-developed grains for this ceramic high-Tc superconductor. Magnetization measurements at various temperatures and fields revealed bulk superconductivity below 80 K. Magnetization versus applied field (M vs. H) loops at various temperatures below the Tc exhibited clear full penetration field HP. In normal state (> 100 K) the susceptibility follows the Curie-Weiss behavior with an effective paramagnetic moment of 9.83 mB.

An assessment of faculty attitudes toward the open source course management system Sakai from an educational perspective
Creators: name: Al-Ali, Maryam A.
Publisher: name: American University
Year: 2023

description: In the recent past, many colleges and universities have begun to seriously consider open source course management systems (CMS) as a way to minimize financial investment and gain control over the software applications they use. As academic institutions make this transition, it is crucial to recognize faculty's perspectives and expectations as key factors in the future success of distance education. Therefore, this study sought to describe faculty attitudes toward the use of Sakai as a tool for enhancing the teaching and learning experience. In particular, the study assessed faculty perspectives with regard to the software and its pedagogical advantages. To isolate the key issues involved, the study investigated the demographic characteristics of faculty, their use of Sakai, their purposes for using it, their perceptions about its pedagogical/technical advantages and disadvantages, and their overall satisfaction. An electronic survey was emailed to 383 faculty members who were using Sakai in their academic courses at four institutions throughout the U.S. Descriptive and inferential statistics were mainly used to analyze the survey data. The major findings demonstrated that most faculty had used Sakai for a very short period of time and mainly to enhance traditional courses. Faculty indicated that personal interest, Sakai's pedagogical effectiveness, and the need to increase course flexibility were the primary factors motivating them to develop courses using Sakai, while grant projects was the least motivating factor. Faculty perceived Sakai's strongest technical advantages to be: organize course materials, provide additional course materials, and provide course security. In terms of Sakai's pedagogical potential, though the majority of faculty were positive about the pedagogical advantages of Sakai in supporting student engagement, collaboration, and learning, a large number also indicated a neutral attitude. Similarly, faculty were neutral, and tended to agree on Sakai's ease of use and its contribution to students' learning. Furthermore, although they were generally satisfied with all the technical aspects, they also reported many technical problems and frustrations with its functionality, user friendliness, and user interface. Finally, faculty were inclined to use Sakai in their future teaching, and overall they were relatively satisfied with it.

description: The spectrum of the hard X-ray background records the history of accretion processes integrated over the cosmic time. Several observational and theoretical evidences indicate that a significant fraction of the energy density is obscured by large columns of gas and dust. X-ray surveys are the most efficient way to trace accretion onto supermassive black holes, since obscured, accreting sources are more difficult to select at all other wavelengths. The current status of hard X-ray surveys after the recent observations carried out with Chandra and XMM-Newton satellites is reviewed along with the results of extensive follow-up multiwavelength observations. In particular recent results concerning the physical and evolutive properties of the supermassive black holes hosted by X-ray selected Active Galactic Nuclei at high redshifts will be discussed.

The efficacy of manipulative material for improving the academic achievement and attitudes of at -risk middle school students
Creators: name: Bangurah, Kolleh Harry Edward
Publisher: name: American University
Year: 2023

description: This study investigated the effects of manipulative materials, reform techniques and constructivist's strategies and traditional methodologies on students who have completed lessons on concepts of algebra through direct encounters with manipulative materials, and students receiving traditional, structured lessons consisting of concept introduction, practice and application. The study involved 34 students in a school in Northeastern section of the District of Columbia. The students were randomly divided into two groups; a manipulative group and a traditional group. The manipulative group was taught mathematics using algebra tiles, reform techniques and constructivists' strategies. Although there were students who did not benefit from the reform approach; significance was found in the attitudes of the manipulative group. To further explore the differences between groups, the researcher used a general guided interview. The traditional group used traditional lessons relying on researcher explanation, work sheets, chalkboard, and textbook. Researcher used varying methods of explanations but no physical models were handled by this group. Examples were written on the chalkboard, and the students practiced problems on paper symbols. Data describing the uses of manipulative materials, reform techniques, using constructivist's strategies were collected using interviews and observations of class sessions to show their impact on the manipulative group. The statistical design used was the analysis of covariance; it was used to adjust for pre-existing differences among the groups, and also to control for the effects of extraneous variables. The analysis explains more of the error variance in the research and to control statistically any initial differences in the students which might have been present and which might have created the differences between the two groups of students. The values of the t-tests in the traditional and the manipulative groups were the same; the values of the significant 2-tailed tests were the same; the mean differences were the same, and the standard error differences were the same. The t-tests for the equality of means indicated that the absolute values of the test statistics were the same.

description: This study investigated the effects of manipulative materials, reform techniques and constructivist's strategies and traditional methodologies on students who have completed lessons on concepts of algebra through direct encounters with manipulative materials, and students receiving traditional, structured lessons consisting of concept introduction, practice and application. The study involved 34 students in a school in Northeastern section of the District of Columbia. The students were randomly divided into two groups; a manipulative group and a traditional group. The manipulative group was taught mathematics using algebra tiles, reform techniques and constructivists' strategies. Although there were students who did not benefit from the reform approach; significance was found in the attitudes of the manipulative group. To further explore the differences between groups, the researcher used a general guided interview. The traditional group used traditional lessons relying on researcher explanation, work sheets, chalkboard, and textbook. Researcher used varying methods of explanations but no physical models were handled by this group. Examples were written on the chalkboard, and the students practiced problems on paper symbols. Data describing the uses of manipulative materials, reform techniques, using constructivist's strategies were collected using interviews and observations of class sessions to show their impact on the manipulative group. The statistical design used was the analysis of covariance; it was used to adjust for pre-existing differences among the groups, and also to control for the effects of extraneous variables. The analysis explains more of the error variance in the research and to control statistically any initial differences in the students which might have been present and which might have created the differences between the two groups of students. The values of the t-tests in the traditional and the manipulative groups were the same; the values of the significant 2-tailed tests were the same; the mean differences were the same, and the standard error differences were the same. The t-tests for the equality of means indicated that the absolute values of the test statistics were the same. It was concluded that the intervention in the traditional group was as effective as that of the manipulative group. There were statistically no significant differences in the achievement of both groups.

description: We investigate observational constraints on the running vacuum model (RVM) of $Λ=3ν(H^{2}+K/a^2)+c_0$ in the spatially curved universe, where $ν$ is the model parameter, $K$ corresponds to the spatial curvature constant, and $c_{0}$ is a constant defined by the boundary conditions. As $\dotΛ \ne 0$, there are energy exchanges between vacuum, matter and radiation in RVM. We study the "geometrical degeneracy" of RVM on the CMB power spectra. By fitting the cosmological data, we find that the values of $χ^2$ in RVM and $Λ$CDM are similar to each other for the non-flat universe. Explicitly, we obtain the constraints of $ν\leq O(10^{-4})$ (68 $\%$ C.L.) and $|Ω_K|\leq O(10^{-2})$ (95 $\%$ C.L.) in our study. In addition, we show that the cosmological constraints of $Σm_ν=0.416^{+0.311}_{-0.407}$ (RVM) and $Σm_ν=0.497^{+0.335}_{-0.387}$ ($Λ$CDM) at 95$\%$ C.L. for the neutrino mass sum are relaxed in both models in the spatially curved universe.

Assessment of noradrenergic mediation of the aversive effects of cocaine
Creators: name: Freeman, Kevin B.
Publisher: name: American University
Year: 2023

description: The propensity to self-administer cocaine may be a function of both its positively reinforcing and aversive effects, with the latter acting as a limiting factor on overall drug-taking. And although the anatomical and neurochemical substrates for cocaine's positively reinforcing effects have been well characterized, relatively little is known about the physiological underpinnings of its aversive effects. Cocaine is a non-selective inhibitor of the three monoamine neurotransmitters dopamine, norepinephrine and serotonin, the first of which appears to be the predominant system mediating cocaine's positively reinforcing effects. To better characterize the relative roles of these systems in the induction of cocaine's aversive effects, the current assessments examined cocaine and other monoaminergic compounds in the conditioned taste aversion (CTA) preparation. Specifically, in Experiment 1, cocaine was compared to three reuptake inhibitors, each possessing relative specificity for one of the three monoamine transporters, in their ability to induce CTAs. Rats were given access to a novel saccharin solution and injected with either cocaine, GBR 12909, desipramine or clomipramine at one of three doses (18, 32 and 50 mg/kg). Desipramine generally induced stronger aversions than GBR 12909 and clomipramine and was the only compound that matched cocaine's aversion acquisition function at all doses (although all compounds conditioned some degree of aversion), suggesting that the noradrenergic system may be the largest monoaminergic contributor to cocaine's aversive effects. To further clarify a role for the this system, cocaine-induced CTAs (10, 18 and 32 mg/kg) were conducted under conditions of antagonism at the norepinephrine alpha1 and beta receptors using prazosin (0.3 mg/kg; Experiment 3) and propranolol (10 mg/kg; Experiment 4), respectively, at doses that were determined to be non-aversive in the CTA preparation (Experiment 2). In each case of noradrenergic antagonism, there was no diminishment in the aversions conditioned with cocaine, suggesting that these effects are mediated by non-noradrenergic NT activity. Furthermore, prazosin and propranolol administration appeared to facilitate the conditioned aversive effects of cocaine. The implications of these findings in regards to other monoaminergic processes are discussed.

description: We use both analytical analyses and numerical simulations to examine the evolution of residual gas within tidally-limited dwarf galaxies and globular clusters. If the gas sound speed exceeds about 10% of the central velocity dispersion, as is the case for ionized gas within small stellar systems, the gas shall have significant density at the tidal radius, and the gas may be lost on timescales as short as a few times the sound crossing time of the system. In colder systems, the density at the tidal radius is much lower, greatly reducing the mass loss rate, and the system may retain its gas for a Hubble time. The tidally removed gas shall follow an orbit close to that of the original host system, forming an extended stream of ionized, gaseous debris. Tidal mass loss severely limits the ability of dwarf systems to continuously form stars. The ordinary gas content in many dwarf galaxies is fully ionized during high red-shift epochs, possibly preventing star formation in some systems, leading to the formation of starless, dark-matter concentrations. In either the field or in the center of galaxy clusters, ionized gas may be retained by dwarf galaxies, even though its sound speed may be comparable to or even exceed the velocity dispersion. These processes may help to explain some observed differences among dwarf galaxy types, as well as observations of the haloes of massive galaxies.

Tidal evolution of galaxies in the most massive cluster of IllustrisTNG-100

description: We study the tidal evolution of galaxies in the most massive cluster of the IllustrisTNG-100 simulation. For the purpose of this work we select 112 galaxies with the largest stellar masses at present and follow their properties in time. Using their orbital history we divide the sample into unevolved (infalling), weakly evolved (with one pericenter passage) and strongly evolved (with multiple pericenters). The samples are clearly separated by the value of the integrated tidal force from the cluster the galaxies experienced during their entire evolution and their properties depend strongly on this quantity. As a result of tidal stripping, the galaxies of the weakly evolved sample lost between 10 and 80% of their dark mass and less than 10% of stars, while those in the strongly evolved one more than 70% of dark and between 10 and 55% of stellar mass, and are significantly less or even not dark matter dominated. While 33% of the infalling galaxies do not contain any gas, this fraction increases to 67% for the weakly evolved and to 100% for the strongly evolved sample. The strongly evolved galaxies lose their gas earlier and faster (within 2-6 Gyr) but the process can take up to 4 Gyr from the first pericenter passage. These galaxies are redder and more metal rich, and at redshift z=0.5 the population of galaxies in the cluster becomes predominantly red. As a result of tidal stirring, the morphology of the galaxies evolves from oblate to prolate and their rotation is diminished thus the morphology-density relation is reproduced in the simulated cluster. The strongly evolved sample contains at least six convincing examples of tidally induced bars and six more galaxies that had their bars enhanced by their interaction with the cluster.

title: Faith in Transition: Christian and Muslim Activist Networks Involved in the Climate Movement
Creators: name: Nita, Maria
Publisher: name: The Open University
Year: 2013

description: This thesis examines the involvement of Christian and Muslim activists with the Climate and Transition Towns Movements, in Britain. It employs a predominantly ethnographic approach and uses a mixed methodology to investigate a varied data (qualitative and quantitative, as well as additional secondary media) gathered during 2007 - 2010. As the Climate and Transition Movements represent the macro level of this research field, this study more broadly profiles these two movements and enquires into how environmental networks organise and expand. It also investigates how the faith networks function alongside or as part of other networks in this field, and how processes of cross-fertilisation take place between them. At a micro level, this thesis is concerned with activists’ identity and with the functions of ecological ritual in the context of my study. This thesis proposes that ecological rituals serve a role in the maintenance of a faith identity in faith networks as well as in creating a new planetary identity in participants. Finally my research shows that rituals and performances aim to engage activists and their audience (the media, society at large) affectively with Climate Change, whilst making these concerns personal to the individual.
