title: Making sense of physics: student teachers' experiences of a physics subject knowledge enhancement course
Creators: name: Inglis, Michael
Publisher: name: The Open University
Year: 2015

description: Concerns about the inadequate supply of secondary school physics teachers in England are widely reported. One attempt to increase supply is the Subject Knowledge Enhancement (SKE) course, intended to develop the physics subject knowledge of non-physics graduates so they can enter an Initial Teacher Education (ITE) course to become physics teachers. Little attention has been given to examining SKE students' experiences of engaging with a subject they last studied at school. In this study, individual semi-structured interviews and focus groups are used within an interpretivist methodology to explore the cases of seven physics SKE course students in one English university. The research is informed by social models of subject knowledge development within a community of practice, with the aim of exploring the students' conceptualisations of subject knowledge and how these develop during ITE, and what they experience as significant for their subject knowledge development. Data analysis is exploratory, utilising grounded theory approaches. Key findings are: students hold diverse beliefs about physics as a body of factual content knowledge; they prioritise the development of confidence at explaining physics as an affective criterion for sufficient subject knowledge; they perceive influential messages about the nature of physics subject knowledge for teaching from the modelling of practice by course tutors; and, interaction with peers and tutors is highly valued, especially during peer-teaching activities where students take it in turns to 'teach' physics to each other. Viewing the SKE course as a community of practice (Wenger, 1998) reveals the importance of sustained interaction, for facilitating development of subject understanding, and the role of ITE tutors for brokering students' entry into the communities of practice of physics and of physics teachers. This research provides support for ITE policies that emphasise the value of university-led subject knowledge development by experienced teacher educators.

RELATIVE EARNINGS MOBILITY OF WOMEN IN THE UNITED STATES

Subjects: classificationCode: 38
subject: Economics

description: Theoretical and empirical studies of earnings mobility have generally focused on relative cross-sectional earnings distributions or on absolute longitudinal changes in individual earnings. Recently, interest has increased in relative earnings mobility, the degree to which individuals' earnings change relative to the earnings of others over time. The pioneering research in this area, however, has been largely empirical. This dissertation proposes a theoretical framework for the study of relative earnings mobility and provides empirical tests of that theory. Relative earnings mobility occurs, in a general sense, when the age-earnings profiles of individuals intersect. Such intersections occur when the slopes of individual age-earnings profiles vary. Many variables are hypothesized to influence the height and slope of these profiles, and thus the likelihood of their intersection. Among these variables are economic class, occupation, industry, unionization, region, cyclical variations, sex, and race. Examining the occupational and industrial distributions of women, their rates of unionization, and so forth, the study hypothesizes that the age-earnings profiles of women are lower, flatter, and less variable than those of men, thus women would be expected to exhibit less relative earnings mobility than men. Subsamples of women by region, industry, race, and age would be expected to exhibit distinct patterns of earnings mobility. Empirical tests are done using the Social Security Administration's Longitudinal Employer-Employee Data file (LEED). For a sample of women continuously employed from 1957 to 1971, a first-order Markov process yields estimates of the rate at which women move between rank-ordered state spaces of a transition probability matrix. The test results are consistent with many of the theoretical propositions. Testing of subsamples shows that rates of relative mobility do vary with sex, and with age, race, industry, and region, as hypothesized.

description: Peritectic growth of bulk superconducting cuprate perovskite, like YBa2Cu3O7-x has been studied. The microstructure features are recalled. The simplest model giving the best description of the microstructure complexity at the mesoscopic scale is an Eden model adapted to chemical reactions. A repulsive dynamical interaction between the front and the solid 211 particles, rejected by the solidifying matrix, is also taken into account. A growth probability-with chemical reaction and pushing-transfer matrix method is developed. The simulations put into evidence the effect of the initial 211 size distribution on the microstructure.

description: In his seminal paper, Bretherton [J. Fluid Mech., 10:166 (1961)] studied the motion of long bubbles in capillary tubes, a situation encountered in many two-phase flow systems. Here, we unveil experimentally and numerically the negative configuration, wherein a long liquid drop formed by the rupture of a liquid plug is stably transported in a capillary tube and surrounded by a flow-induced air cushion. After a careful theoretical and numerical analysis of the drop formation process, we show that the shape of the drop and lubricating air film is reminiscent of Bretherthon's calculation and can be inferred from an adapted analytical theory. This work opens tremendous perspectives for drop fast transport in microfluidic systems without walls contamination and friction.

These coefficients are required to implement 1-loop O($a$) improvement in full QCD simulations for the coupling with the improved gauge actions. To this order, lattice artifacts of step scaling function for each improved gauge action are also investigated. In addition, passing through the SF scheme, we estimate the ratio of $Λ$-parameters between the improved gauge actions and the plaquette action more accurately.

title: Student complaint behaviour in a higher education institution
Creators: name: Millward, Christine Vanessa
Publisher: name: The Open University

description: Universities in the English higher education sector are increasingly concerned about the impact of students’ complaints. The introduction of the Office of the Independent Adjudicator for Higher Education (OIA) in 2004 sees rising numbers of students referring their dissatisfaction externally and the subsequent publishing of OIA decisions against named universities from 1st April 2012 places students’ complaints as high risk for reputational damage. With minimal empirical research evidencing the student complaint experience, higher education stakeholders perceive the introduction of tuition fees and an associated discourse of consumer entitlement to be the drivers of student dissatisfaction. Taking a pragmatic approach, this case study explores the influences on student complaint behaviour at Riverside University, a post-1992 ‘new’ university with a widening participation mission. Grounded Theory techniques are utilised to analyse students’ written complaints submitted to the university across a period of four academic years, 2006-2007 to 2009-2010. The focus on the students’ perspective is supported by illustrative comments from complainants’ online interviews. Analysis demonstrates that the complaint journey is highly emotional and stressful as complainants interact with a culture that is not receptive to dissatisfied students. It also exposes the layered nature of complaints in a higher education environment: the ‘trigger’ issue initiating complaint behaviour sits over matters of previously suppressed discontent which subsequently shape the nature of the complaint. The research concludes that complaint behaviour is not linked to consumerist principles; students are not influenced by the level of fees paid. Complaints focus on assessment failure and degree classifications. Students’ disappointment with an assessment result is the significant motivator of complaint behaviour. Reaction to their academic standing represents the duality of students’ understanding of higher education: achievement is expected as a transactional process and carries instrumental aspirations for their future, which some articulate in terms of employment. The focus on the value of their award as embodying hopes for their future is a unifying influence on student complaint behaviour across the diversity of the student complaint body.

THE INTERNATIONAL IMPLICATIONS OF WEATHER AND CLIMATE MODIFICATION

description: This treatise is intended to further needed research into a relatively new and important area of international relations: "ecopolitics." While "ecopolitics" includes a multitude of ecological issues and their impact on the global political system, the scope of this study is limited to the international implications of weather and climate modification. It has become increasingly evident that new approaches to the study of international relations must be utilized to understand fully the potential impact of mnay new issues on the international system. For example, an "ecopolitical" perspective--where concerns are focused on environmentally related problems at the national, regional, and global levels--has received increased attention. More specifically, environmentally related issues such as weather and climate modification likely will assume greater significance as environmental degradation accelerates and technological innovation allows more ambitious environmental modification programs. The effects of weather and climate transcend national boundaries; thus, attempts to control the weather, and to a greater extent the climate, will of necessity be intenational in nature. Furthermore, inadvertent weather and climate modification through pollution and man's activities also have global political ramifications. In the final analysis, environmental modification for the benefit of mankind is contingent upon the degree of internnational cooperation exhibited by the nations actively engaged in weather and climate modification and control. Moreover, effective global management of environmental issues is a prerequisite for minimizing the potential for conflict and maximizing cooperation. One of the principal barriers to the effective management of global commons issues is the fact that the creation of the necessary institutional arrangements generally lag behind politicization of the issue. While the process of creating an effective international body to monitor and manage environmental modification undoubtedly will be difficult and protracted, it is imperative that efforts in this direction be initiated now before such modification becomes a volatile political issue. Based on the above considerations, I propose that an international authority--closely patterned after the International Seabed Authority--be created to manage environmental modification for the global good.

description: In this paper, we estimate the effect of primary school teachers’ gender biases on boys’ and girls’ academic achievements during middle and high school and on the choice of advanced level courses in math and sciences during high school. For identification, we rely on the random assignments of teachers and students to classes in primary schools. Our results suggest that teachers’ biases favoring boys have an asymmetric effect by gender— positive effect on boys’ achievements and negative effect on girls’. Such gender biases also impact students’ enrollment in advanced level math courses in high school—boys positively and girls negatively. These results suggest that teachers’ biased behavior at early stage of schooling have long run implications for occupational choices and earnings at adulthood, because enrollment in advanced courses in math and science in high school is a prerequisite for post-secondary schooling in engineering, computer science and so on. This impact is heterogeneous, being larger for children from families where the father is more educated than the mother and larger on girls from low socioeconomic background.

description: Meteoroids impacting the Earth atmosphere are commonly classified using the PE criterion. This criterion was introduced to support the identification of the fireball type by empirically linking its orbital origin and composition characteristics. Additionally, it is used as an indicator of the meteoroid tensile strength and its ability to penetrate the atmosphere. However, the level of classification accuracy of the PE criterion depends on the ability to constrain the value of the input data, retrieved from the fireball observation, required to derive the PE value. To overcome these uncertainties and achieve a greater classification detail we propose a new formulation using scaling laws and dimensionless variables that groups all the input variables into two parameters that are directly obtained from the fireball observations. These two parameters, $α$ and $β$, represent the drag and the mass loss rates along the luminous part of the trajectory, respectively, and are linked to the shape, strength, ablation efficiency, mineralogical nature of the projectile, and duration of the fireball. Thus, the new formulation relies on a physical basis. This work shows the mathematical equivalence between the PE criterion and the logarithm of $2αβ$ under the same PE-criterion assumptions. We demonstrate that $log(2αβ)$ offers a more general formulation which does not require any preliminary constraint on the meteor flight scenario and discuss the suitability of the new formulation for expanding the classification beyond fully disintegrating fireballs to larger impactors including meteorite-dropping fireballs. The reliability of the new formulation is validated using the Prairie Network meteor observations.

description: Cavity optomechanics and electromechanics form an established field of research investigating the interactions between electromagnetic fields and the motion of quantum mechanical resonators. In many applications, linearised form of the interaction is used, which allows for the system dynamics to be fully described using a Lyapunov equation for the covariance matrix of the Wigner function. This approach, however, is problematic in situations where the Hamiltonian becomes time dependent as is the case for systems driven at multiple frequencies simultaneously. This scenario is highly relevant as it leads to dissipative preparation of mechanical states or backaction-evading measurements of mechanical motion. The time-dependent dynamics can be solved with Floquet techniques whose application is, nevertheless, not straightforward. Here, we describe a general method for combining the Lyapunov approach with Floquet techniques that enables us to transform the initial time-dependent problem into a time-independent one, albeit in a larger Hilbert space. We show how the lengthy process of applying the Floquet formalism to the original equations of motion and deriving a Lyapunov equation from their time-independent form can be simplified with the use of properly defined Fourier components of the drift matrix of the original time-dependent system. We then use our formalism to comprehensively analyse dissipative generation of mechanical squeezing beyond the rotating wave approximation. Our method is applicable to various problems with multitone driving schemes in cavity optomechanics, electromechanics, and related disciplines.

ECONOMIC EFFECTS OF DEVALUATION: PERU 1975-1978
Creators: name: Daly, Jorge Luis
Publisher: name: American University
Year: 2023

description: This dissertation seeks to examine the effects of devaluation on the Peruvian economy within the context of the economic stabilization policies that were applied in the period 1975-1978. It is an empirical effort to demonstrate that devaluation policies are likely to contract the growth of national output and redistribute income against the underprivileged. Conventional economic theory predicts that devaluation policies should help the economy restore equilibrium in the external sector and move it to the level of full employment of resources. This, however, ignores critical features of a less developed economy such as the nature of exports and imports, and also the income effects caused by devaluation that lead to a contraction in aggregate demand. Devaluation did contract the growth of national output in Peru and altered significantly an already uneven income distribution. These effects were more strongly felt in the period 1977-1978, when free forces in the foreign exchange market were left to establish the price of the exchange rate. The study also provides an alternative approach to deal with the theoretical rationale of devaluation policies, based on the concept of mode of accumulation.
AMS sustainable food truck : technology assessment & energy management

description: The AMS at UBC has a goal to drastically reduce the Green House Gas emission in the next decade. For such manner, a sustainable food truck fits their purpose and the culture of the city of Vancouver. This project involves a simulation system as well as an energy management algorithm to predict the behaviour of the electrical system of the truck and to best suit its needs, considering all the equipment is powered by solar panels (as a primary source), fuel cells (secondary source) and a battery (back-up source). Also, the project includes the implementation of each subsystem and their integration to the point where the relevant data can be displayed on the screen. The user will be able to customize the simulations, choosing which subsystem will be turned on or off. Scenarios for the simulations were tested, such as a busy sunny day (during summer), providing enough data to state that the mobility system of the truck may not be supported by the sources. Moreover, unless the technologies for equipment and energy generation are well chosen, energy shortage might be expected in bad-case scenarios, such as a cloudy day. The results of these simulations will be used to create and design specifications of the truck's energy systems in future stages of the AMS Sustainable Food Truck project.

description: We employ a novel, unbiased renormalization-group approach to investigate non-equilibrium phase transitions in infinite lattice models. This allows us to address the delicate interplay of fluctuations and ordering tendencies in low dimensions out of equilibrium. We study a prototypical model for the metal to insulator transition of spinless interacting fermions coupled to electronic baths and driven out of equilibrium by a longitudinal static electric field. The closed system features a Berezinskii-Kosterlitz-Thouless transition between a metallic and a charge-ordered phase in the equilibrium limit. We compute the non-equilibrium phase diagram and illustrate a highly non-monotonic dependence of the phase boundary on the strength of the electric field: For small fields, the induced currents destroy the charge order, while at higher electric fields it reemerges due to many-body Wannier-Stark localization physics. Finally, we show that the current in such an interacting non-equilibrium system can counter-intuitively flow opposite to the direction of the electric field. This non-equilibrium steady-state is reminiscent of an equilibrium distribution function with an effective negative temperature.

description: This paper focuses on the use of interest rates as a tool for hedging against the default risk of heterogeneous hedge funds (HFs) in a leveraged market. We assume that the banks study the HFs survival statistics in order to compute default risk and hence the correct interest rate. The emergent non-trivial (heavy-tailed) statistics observed on the aggregate level, prevents the accurate estimation of risk in a leveraged market with heterogeneous agents. Moreover, we show that heterogeneity leads to the clustering of default events and constitutes thus a source of systemic risk.

description: On the basis of the time-dependent Ginzburg-Landau equation we studied the dynamics of the superconducting condensate in a wide two-dimensional sample in the presence of a perpendicular magnetic field and applied current. We could identify two critical currents: the current at which the pure superconducting state becomes unstable ($J_{c2}$ \cite{self1}) and the current at which the system transits from the resistive state to the superconducting state ($J_{c1}

CONTESTED CHILD CUSTODY CASES: AN EXAMINATION OF CUSTOM AND FAMILY LAW IN AN AMERICAN COURT
Creators: name: Girdner, Linda K.
Publisher: name: American University
Year: 2023

description: The problem addressed in this research can be stated in the following two questions: (1) What is the relationship between legal and extralegal categories in contested child custody cases which arise out of divorce proceedings in the United States? (2) In what ways does the interrelationship of the legal and extralegal categories invoked in such proceedings express an ideology of the family and formulate a code for conduct for family members? Legal categories include concepts and rules which derive from procedural and substantive law and which serve to structure the process and limit the information admissible in court. Extralegal categories refer to the norms and symbols about family and sex roles which are expressed in these cases. The research involved the analysis of contested child custody cases between mothers and fathers, using an ethnosemantic approach and situational analysis. The fieldwork took place in a circuit court and family court in the United States. The data from the hearings were supplemented by information from public records, by interviews with judges, and by attendance at meetings of a fathers' advocacy group. From the interrelationship between the legal and extralegal criteria a code for conduct is extracted, which consists of a set of norms as to how children should be raised and how parents should act. Derived from this code are certain ideas and meanings about family, motherhood, fatherhood, love and duty. These form an organized set of symbols which can be understood apart from the norms and which constitutes an ideology of the family. Within this ideology motherhood and fatherhood are defined differently. Parents and their attorneys manipulate these symbols and elements of the code for conduct to win favorable decisions. In litigating custody parents relinquish their decision making power to the state. Judges are placed in the position of making decisions affecting the internal functioning of the family. They scrutinize the moral as well as jural aspects of the parent-child relationship to ascertain what is in the "best interests of the child.".

description: Trapping electrons in quantum dots and controlling their collective quantum states is crucial for converting semiconductor structures into bits of quantum information processing. Here, we study single- and two-particle states in quantum dots formed in gapped bilayer graphene (BLG), where the electron's valley states appear in pair with their spin quantum number and we analyse spin- and valley-singlet and triplet states for various BLG and dot parameters, as well as two-particle interaction strength and external magnetic field.

RUSSIAN-SPEAKING MIGRANTS OF “ADVANCED WOMEN” CATEGORY IN EUROPE: COMMUNICATION AND INTEGRATION COMPETENCES (RESULTS OF SURVEY)
Creators: name: Sandler Margarita
Publisher: name: Cross Cultural Studies: Education and Science
Year: 2021
Subjects: social adaptation; Russian-speaking migrants; Women-Migrants Advanced (WMA); cross-cultural communication; entrepreneurial skills of migrants; level of tolerance

description: The research, conducted by the IMAGRI – Institute in Europe (NGO), allows answering the question about the attitude of the Russian-speaking migrants to European values. The Institute started its activities in Brussels in 2009. The category of WMA (Women-Migrants Advanced) has highly developed cross-cultural communication skills but in about half the cases it does not solve the problem of self-realization in their careers and in the society; for the category these concepts are inseparable. “Our” category of migrants, whose number has increased in Europe, requires special integration programs through entrepreneurship, as our project RESTART (2011-2014) has proved its effectiveness. The research is conducted on the basis of communication with migrants and monitoring processes that are currently activated in Russian diaspora. The focus of the research and monitoring is a gender (women’s) group. According to many reports, women make the majority of living in Europe, being present in a significant number in all sectors of migration: family migration (both creation and family reunification), intellectual migration (both professionals and specialists as family members) and labor migration (mainly from the post-Soviet space but not from Russia). According to experts, they are the “invisible majority” in the Russian migration to Europe. However, by working on research projects in the sphere of migrant women, establishing contacts with various community organizations, consulting experts, we draw attention to the fact that, first of all, that women are not only a significant part of immigration but also extremely active (both socially and culturally) part of it.
Construction and verification of a prognostic-related model of rectal cancer based on microRNAs

Subjects: subject: 111203 Cancer Genetics
subject: FOS: Clinical medicine

description: Both the miRNA and the corresponding clinical data were collected from The Cancer Genome Atlas (TCGA). We used univariate Cox analysis to screen the miRNA related to prognosis. Multivariate Cox analysis was used to construct a prognostic model. According to this, the samples were randomly divided into training group and verification group, and the two groups were divided into high-risk score group and low-risk score group according to the risk scores. The predictive ability of the model was verified by survival analysis, ROC curve, and survival state chart.

Going in circles is the way forward: the role of recurrence in visual inference

description: Biological visual systems exhibit abundant recurrent connectivity. State-of-the-art neural network models for visual recognition, by contrast, rely heavily or exclusively on feedforward computation. Any finite-time recurrent neural network (RNN) can be unrolled along time to yield an equivalent feedforward neural network (FNN). This important insight suggests that computational neuroscientists may not need to engage recurrent computation, and that computer-vision engineers may be limiting themselves to a special case of FNN if they build recurrent models. Here we argue, to the contrary, that FNNs are a special case of RNNs and that computational neuroscientists and engineers should engage recurrence to understand how brains and machines can (1) achieve greater and more flexible computational depth, (2) compress complex computations into limited hardware, (3) integrate priors and priorities into visual inference through expectation and attention, (4) exploit sequential dependencies in their data for better inference and prediction, and (5) leverage the power of iterative computation.
Pion and Kaon masses in Staggered Chiral Perturbation Theory

description: We show how to compute chiral logarithms that take into account both the $\cO(a^2)$ taste-symmetry breaking of staggered fermions and the fourth-root trick that produces one taste per flavor. The calculation starts from the Lee-Sharpe Lagrangian generalized to multiple flavors. An error in a previous treatment by one of us is explained and corrected. The one loop chiral logarithm corrections to the pion and kaon masses in the full (unquenched), partially quenched, and quenched cases are computed as examples.
