description: We and that integration between pay networks and cable systems has substantial effects on final market outcomes. Cable systems owned by the two MSOs (Multiple Cable Television System Operators) having majority ownership ties with major pay cable networks tended to carry their affiliated networks more frequently and rival networks less frequently than did the average non-integrated system. Systems of at least one of these MSOs offered fewer pay networks in total than the average non-integrated system. With respect to pricing and other marketing behavior, results suggest that systems in these MSOs favor affiliated networks, but there was less evidence that they discriminate against rival networks.

description: The UBC Food System Project is a collaborative, community-based action research project involving multiple partners and collaborators to transform the current UBC food system into a more sustainable and environmental friendly food system. With consultations and continuing dialogue with the project partners and collaborators, the UBCFSP team developed a series of scenarios relating to specific aspects of the UBC food system. The scenario our group had the opportunity to investigate was the sustainability of UBC Sprouts. Sprouts is a volunteer run organization at the University of British Columbia dedicated to providing the community with sustainable and healthy food. To assess the sustainability of Sprouts, our group decided to conduct a commodity chain analysis of one of their soups. Our research revealed that most of the ingredients of the soup were supplied locally by Discovery Organics. The vegetables for the soup were all produced by farms located within British Columbia. The UBC farm supplies some of Sprouts’ vegetables, but is not exclusively used for soup production. It is instead sold at the grocery store section of Sprouts. We examined the kitchen area, as well as the food preparation procedures involved in making the selected soup. Through analyzing the findings, our group was able to generate recommendations regarding the sustainability practices for Sprouts, as well as suggestions for future AGSC 450 students. Our commodity chain analysis confirmed the sustainability of Sprouts, which supports UBC’s movement towards a more sustainable and carbon-neutral campus.

title: Literary Practices and the Curriculum Context: Exploring the Production of Assignments in a South African Vocational Higher Education Institution
Creators: name: Coleman, Lynn
Publisher: name: The Open University
Year: 2014

description: This thesis explores curriculum construction and the production of assignments in two courses at a vocational higher education institution in South Africa, namely Film and Video Technology and Graphic Design. The influence of the vocational curriculum context on student and lecturer practices is examined through two analytical frameworks, literacy as social practice and Bernstein's concept of recontextualisation. An ethnographic methodology was used to investigate the broader curriculum context and literacy practices engaged in by students and lecturers. Fieldwork was carried out over a six-month period, while generating and collecting fieldnote, interview, documentary and photographic data. The analysis is presented as two separate case studies, one in each department. The study's interpretive approach is used to bring together the Bernstein focus on recontextualisation and curriculum with the Academic Literacies notion of literacy practice. The significant role of the curriculum context in the patterning of the literacy practices students engage in when producing their assignments is therefore recognised. The findings highlight the way the university of technology sectoral domain operates as a third aspect in the recontextualisation process alongside the professional and disciplinary domains, resulting in conflicting messages. Primacy is given to texts and literacy practices that resemble those in the professional domains. However, essayist literacies are also foregrounded and reflect generic and decontextualized understandings of writing that function as an important mechanism through which the sectoral domain asserts its position in the academy. The research demonstrates that the Academic Literacies and Bernsteinian frames can successfully be combined in empirical research, allowing the individual students' experiences to be located within broader institutional and sectoral structures in a way that challenges deficit views of the student. A further conclusion drawn is how an Academic Literacies lens can help to identify the workings of the sectoral domain thus broadening the analytical frame beyond individual institutional conditions.

We show that $L(E,τ,1)$, the special value at $s=1$ of the $L$-function of the twist of $E$ by $τ$, divided by the classical transcendental period $Ω_{+}^{d^+}|Ω_{-}^{d^-}|ε(τ)$ is algebraic and Galois-equivariant, as predicted by Deligne's conjecture.

description: In the context of Einstein-aether scalar field cosmology we solve the field equations and determine exact and analytic solutions. In particular, we consider a model proposed by Kanno and Soda where the aether and the scalar fields interact through the aether coefficient parameters, which are promoted to be functions of the scalar field. For this model, we write the field equations by using the minisuperspace approach and we determine the scalar field potentials which leads to Liouville--integrable systems. We solve the field equations for five families of scalar field potentials and, whether it is feasible, we write down the analytic solutions by using closed-form functions.

Efficient Estimations of Random Coefficients Model Based on Survey Data

Year: 1992
Subjects: Research Methods/ Statistical Methods

description: Much applied work in econometrics and other social sciences involves regression analysis using survey data. Recently, King and Evans (1986) and Bhatti (1991) considered an equicorrelated error term model with fixed coefficients and proposed some diagnostic tests for detecting the equicorrelated parameter (p). This paper considers an efficient estimation procedure for the linear regression model with stochastic coefficients and equicorrelated disturbances across blocks. An algorithm for the maximum likelihood estimator is presented, after King (1986), for an error components model. Its application to model based on Bangladesh data is discussed.
Order parameter phase locking as a cause of a zero bias peak in the differential tunneling conductance of bilayers with electron-hole pairing

description: In n-p bilayer systems an exotic phase-coherent state emerges due to Coulomb pairing of n-layer electrons with p-layer holes. Unlike Josephson junctions, the order parameter phase may be locked by matrix elements of interlayer tunneling in n-p bilayers. Here we show how the phase locking phenomenon specifies the response of the electron-hole condensate to interlayer voltages. In the absence of an applied magnetic field, the phase is steady-state (locked) at low interlayer voltages, VV_c. The change in the system dynamics at V=V_c gives rise to a peak in the differential tunneling conductance. The peak width V_c is proportional to the absolute value of the tunneling matrix element |T_{12}|, but its height does not depend on |T_{12}|; thus the peak is sharp for small |T_{12}|. A sufficiently strong in-plane magnetic field reduces considerably the peak height. The present results are in qualitative agreement with the zero bias peak behavior that has recently been observed in bilayer quantum Hall ferromagnets with spontaneous interlayer phase coherence.

description: The main sequence offers a method for the systematization of quasar spectral properties. Extreme FeII emitters (or extreme Population A, xA) are believed to be sources accreting matter at very high rates. They are easily identifiable along the quasar main sequence, in large spectroscopic surveys over a broad redshift range. The very high accretion rate makes it possible that massive black holes hosted in xA quasars radiate at a stable, extreme luminosity-to-mass ratio. After reviewing the basic interpretation of the main sequence, we report on the possibility of identifying virial broadening estimators from low-ionization line widths, and provide evidence of the conceptual validity of redshift-independent luminosities based on virial broadening for a known luminosity-to-mass ratio.

description: Photocatalysis induced by sunlight is one of the most promising approach to environmental protection, solar energy conversion and sustainable production of fuels. The computational modeling of photocatalysis is a rapidly expending field which requires to adapt and further develop the available theoretical tools. The coupled transfer of proton and electron is an important reaction during photocatalysis. In this work, we present the first step of our methodology development in which we apply existing kinetic theory of such coupled transfer to a model system, namely, methanol photo-dissociation on rutile TiO$_2$(110) surface, with the help of high-level first-principles calculations. Moreover, we adapt the Stuchebrukhov-Hammes-Schiffer kinetic theory, where we use the Georgievskii-Stuchebrukhova vibronic coupling, to calculate the rate constant of the proton coupled electron transfer reaction for a particular pathway. In particular, we propose a modified expression to calculate the rate constant which enforces the near-resonance condition for the vibrational wavefunction during proton tunneling.

description: We introduce a deterministic self-organized critical system that is one dimensional and bulk driven. We find that there is no universality class associated with the system. That is, the critical exponents change as the parameters of the system are changed. This is in contrast with the boundary driven version of the model [M. de Sousa Vieira, Phys. Rev. E 61 (2000) 6056] in which the exponents are unique. This model can be seen as a discretized version of the conservative limit of the Burridge-Knopoff model for earthquakes.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Recently, some authors have considered the quantum spectrum of black holes. This consideration is extended to tachyonic black holes in a brane-anti-brane system. In this study, black holes are constructed from two branes which are connected by a tachyonic tube. As the branes come closer to each other, they evolve and make a transition to thermal black branes. It will be shown that the spectrum of these black holes depends on the tachyonic potential and the separation distance between the branes. By decreasing the separation distance, more energy emerges and the spectrum of the black hole increases.

description: The cointegration tests of Engle and Granger (1987) test the null hypothesis of no cointegration. We extend the unit root testing framework of Kwiatkowski et al (1992) to testing the null hypothesis of cointegration. A test is developed which is asymptotically equivalent to the locally best invariant.(LBI) test and is applicable to a wide range of non-stationary data generating processes. The asymptotic distribution of our test statistic is found to be free of nuisance parameters, and is dependent only on the number of regressors in the cointegrating regression. We tabulate asymptotic critical values for the test based on this distribution, and report on a small power comparison with the Dickey-Fuller test.

The new test also provides far more reliable estimates of the location of the structural break.

description: This paper outlines several difficulties with testing economic theories, particularly that the theories may be vague, may relate to a decision interval different from the observation period and may need construction of a metric to convert a complicated testing situation to an easier one. We argue that it is better to use model selection procedures rather than formal hypothesis testing when asking the data to decide on model specification. This is because testing favors the null hypothesis, typically uses an arbitrary choice of significance level and researchers working with the same data could easily end up with different final models, which would make policy recommendations difficult.
O-plane Backreaction and Scale Separation in Type IIA Flux Vacua

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We construct AdS$_4$ flux vacua of type IIA string theory in the supergravity (large volume, small $g_s$) regime, including the backreaction of O6-planes. Our solutions are the localized versions of the smeared solutions on Calabi-Yau orientifolds studied by DeWolfe, Giryavets, Kachru and Taylor and in other works. We find that the O-plane backreaction in these solutions generates warping, a varying dilaton, non-closed RR field strengths and internal curvature. Just like their smeared counterparts, the localized solutions admit stabilized moduli, a parametric control over string corrections and a parametric separation between the AdS and KK scales. Our explicit expressions furthermore make precise the common lore that smeared solutions should approximate the exact ones in the large-volume, small-$g_s$ limit. Finally, our solutions appear to violate a recent swampland conjecture about an absence of scale separation in supersymmetric AdS vacua. We make a simple observation explaining why this happens in these solutions in contrast to most other AdS solutions in string theory.

Subjects: Choral conducting, music education.

description: Abstract: This study explores the unique challenges and effective strategies in teaching choral conducting within church music education programs. While choral conducting is crucial in worship settings, the pedagogical approaches specific to church contexts remain underexplored. This research aims to identify the primary challenges faced by educators, compare them with secular settings, and uncover successful teaching strategies. A mixed-methods approach was employed, involving 50 choral conducting educators from various U.S. church music programs. Data collection included surveys, in-depth interviews with 15 participants, remote observations of 10 classes, and analysis of course materials. Quantitative data were analyzed using descriptive statistics, while qualitative data underwent thematic analysis. Results revealed that integrating spiritual elements with technical skills (86%) and addressing diverse musical backgrounds (72%) were primary challenges. Compared to secular education, the need to incorporate theological understanding into conducting technique (91%) emerged as a significant difference. Effective strategies included integrated curriculum approaches (88% success rate), mentorship programs (75%), and technology integration for self-assessment (70%). Educators reported improved student outcomes in sacred text interpretation (65% improvement) and spiritual leadership confidence (72% enhancement). The findings highlight the complex nature of teaching choral conducting in church settings, emphasizing the need for specialized approaches that blend musical, theological, and pedagogical expertise. This study contributes to developing more comprehensive educational programs for church choir conductors, addressing the unique intersection of musical artistry and spiritual leadership. Future research should explore long-term career outcomes and global perspectives in church music education.

description: In the cut-throat 1990s the key to survival for a business is a knowledge of customer needs. At the same time the utilisation of Quality Management principles are required for efficiency, productivity and the elimination of waste. Clearly, there is a need for a quantitative tool that can directly use the "voice of the customer". Quality Function Deployment (QFD) is a simple yet visually powerful planning tool for ensuring that customer demands are accurately translated into relevant technical requirements and actions throughout each stage of product development. This working paper will discuss the development of QFD and the use of statistical techniques within the QFD framework.

description: Increasingly survey data is being used in regression analysis. If disturbance correlation arising from block and/or subblock random effects is ignored, it can lead to inefficient regression estimates and predictions as well as misleading inferences. This paper addresses the problem of testing for subblock effects in the presence of block effects in a three-stage sampling regression model. Point optimal invariant (POI) and one-sided and two-sided Lagrange multiplier (LM) tests are constructed. An empirical comparison of the sizes and powers of two versions of the POI tests and the two LM tests is reported. It reveals that the true size of the one-sided LM test is about one-half of its nominal size and that the two-sided LM test lacks power. The POI tests are found to have extremely desirable small-sample properties.

description: This thesis discusses the development of Charge-Couple Device (CCD) and Electron Multiplying CCD (EM-CCD) technology for high resolution X-ray spectroscopy. Of particular interest is the spectral resolution performance of the devices alongside the optimisation of the quantum efficiency through the use of back-illuminated CCDs, thin filter technology and improved passivation techniques. The early chapters (1 through 5) focus on the background and theory that is required to understand the purpose of the work in this thesis and how semiconductors can be used as the detector of high resolution X-ray spectrometers. Chapter 6 focuses on the soft X-ray performance of three different types of conventional CCD using the PTB beamline at BESSY II. The results show that there is degradation in spectral resolution in all three devices below 500 eV due to incomplete charge collection and X-ray peak asymmetry. The Hamamatsu device is shown to degrade faster than the CCD30-11 variants and this is attributed to the thickness of the active silicon (>50 μm) in the device and also its thicker dead-layer (~75 nm) which is found by evaluating the device's soft X-ray QE). The charge loss at the back-surface generation/recombination centres is also investigated and is found to be higher in the Hamamatsu device, again due to its thicker dead-layer. Chapter 7 is an investigation of the Modified Fano Factor which aims to describe the spectral resolution degradation that is expected when an EM-CCD is used to directly detect soft X-rays. The factor is predicted analytically, modelled and then verified experimentally allowing EM-CCD performance over the soft X-ray range to be predicted with high levels of confidence. Chapter 8 is a detailed look into work completed for the phase 0 study of the off plane X-ray grating spectrometer on the International X-ray Observatory. The work includes a detailed contamination study, effective area analysis, the pointing knowledge requirement and the use of filters to minimise optical background.

description: We consider possibilities to grasp and drag one-dimensional solitons in two-component Bose- Einstein condensates (BECs), under the action of gravity, by tweezers induced by spatially confined spin-orbit (SO) coupling applied to the BEC, with the help of focused laser illumination. Solitons of two types are considered, semi-dipoles and mixed modes. We find critical values of the gravity force, up to which the solitons may be held or transferred by the tweezers. The dependence of the critical force on the magnitude and spatial extension of the localized SO interaction, as well as on the solitons norm and speed (in the transfer regime), are systematically studied by means of numerical methods, and analytically with the help of a quasi-particle approximation for the soliton. In particular, a noteworthy finding is that the critical gravity force increases with the increase of the transfer speed (i.e., moving solitons are more robust than quiescent ones). Nonstationary regimes are addressed too, by considering abrupt application of gravity to solitons created in the weightless setting. In that case, solitons feature damped shuttle motion, provided that the gravity force does not exceed a dynamical critical value, which is smaller than its static counterpart. The results may help to design gravimeters based on ultracold atoms.

description: We classify all regular solutions of the Yang-Baxter equation of eight-vertex type. Regular solutions correspond to spin chains with nearest-neighbour interactions. We find a total of four independent solutions. Two are related to the usual six- and eight-vertex models that have R-matrices of difference form. We find two completely new solutions of the Yang-Baxter equation, which are manifestly of non-difference form. These new solutions contain the S-matrices of the AdS2 and AdS3 integrable models as a special case. Consequently, we can classify all possible integrable deformations of eight-vertex type of these holographic integrable systems.

description: We investigate interfacial structural and fluctuation effects occurring at continuous filling transitions in 3D wedge geometries. We show that fluctuation-induced wedge covariance relations that have been reported recently for 2D filling and wetting have mean-field or classical analogues that apply to higher-dimensional systems. Classical wedge covariance emerges from analysis of filling in shallow wedges based on a simple interfacial Hamiltonian model and is supported by detailed numerical investigations of filling within a more microscopic Landau-like density functional theory. For sufficiently short-ranged forces mean-field predictions for the filling critical exponents and covariance are destroyed by pseudo-one-dimensional interfacial fluctuations. In this filling fluctuation regime we argue that the critical exponents describing the divergence of lengthscales are related to values of the interfacial wandering exponent $ζ(d)$ defined for planar interfaces in (bulk) two-dimensional ($d=2$) and three-dimensional ($d=3$) systems, recovering the known results for pure (thermal disorder) systems and predicting universal critical exponents for the case of random-bond disorder. Finally we revisit the transfer matrix theory of three-dimensional filling based on an effective interfacial Hamiltonian model and discuss the interplay between breather, tilt and torsional interfacial fluctuations.

description: The microbiological quality of fresh and smoked fishes sold around selected markets (Mile 3, Mile 1 and Creek Road) in Port Harcourt City was carried out. The microbial count of the fresh fish was higher than that of the smoked ones. The bacterial count of the fresh fish ranged from 0.35×101cfu/g (Salmonella) to 1.6918×103 cfu/g(Total Bacterial Count) and the smoked one ranged from 0.5×101cfu/g(Salmonella) to 1.042×103cfu/g (Total Bacterial Count). The fungal load of the fishes ranged between 1.867×102cfu/g for the smoked and 4.860×102,cfu/g) for the fresh ones. Statistically, there was no significant difference between the fresh and smoked fish with respect to microbial load at p<0.05. The moisture content of the fresh fish was higher (74.48±4.52) than that of the smoked fish (53.48±2.06) just like the pH of the fresh (6.57±0.10) and smoked fish (6.17±0.14). The bacteria and fungi isolated from fish in the Creek road market (1550±265cfu/g, 381.50±1.75cfu/g) were significantly higher/different from those of the mile 3 market (1262.50±310cfu/g, 307.50±1.69cfulg) and the mile 1 market (1287.75±6.15cfu/g, 315±197cfu/g) at p<0.05. Bacillus substilis Krebsiella spp, Staphylococcus aureus and Streptococcus spp were found only on smoked fish while Acinetobacter spp, Corynecbacteruim spp, Flavobacterium spp, Enterobacter spp and Salmonella species were found on fresh. Bacteria like Escherichia coli, Micrococcus luteus, Pseudomonas aeruginosa, Proteus spp and Serratia spp were found on both fresh and smoked fish. Fungal species such as Penicillium expansum, Aspergillu spp, Fusarium spp, Rhizopus stolonifer and Mucor piriformis were found on both fresh and smoked fish. The microbial metries or count showed that they all exceeded the permissible limits of the World Health Organization (WHO), Standard Organization of Nigeria (SON) and the National Environmental Standard Regulation Enforcement Agency (NESREA). The microbial count showed some level of contamination under the influenced of pH and moisture. It is therefore crucial to implement strict hygiene and safety standards throughout the fish supply chain to mitigate these risks of consuming contaminated seafood.

description: We consider the problem $\inf\big\{ \int\!\!\int_Ω(1 + |\nabla u(x,y)|^2)^{-1} dx dy : \text{ the function } u : Ω\to \mathbb{R} \text{ is concave and } 0 \le u(x,y) \le M \text{ for all } (x,y) \in Ω=\{ (x,y): x^2 + y^2 \le 1 \} \, \big\}$ (Newton's problem) and its generalizations. In the paper \cite{BrFK} it is proved that if a solution $u$ is $C^2$ in an open set $\mathcal{U} \subset Ω$ then $\det D^2u = 0$ in $\mathcal{U}$. It follows that graph$(u)\rfloor_\mathcal{U}$ does not contain extreme points of the subgraph of $u$. In this paper we prove a somewhat stronger result. Namely, there exists a solution $u$ possessing the following property. If $u$ is $C^1$ in an open set $\mathcal{U} \subset Ω$ then graph$(u\rfloor_\mathcal{U})$ does not contain extreme points of the convex body $C_u = \{ (x,y,z) :\, (x,y) \in Ω,\ 0 \le z \le u(x,y) \}$. As a consequence, we have $C_u = \text{\rm Conv} (\overline{\text{\rm Sing$C_u$}})$, where Sing$C_u$ denotes the set of singular points of $\partial C_u$. We prove a similar result for a generalized Newton's problem.

title: Governance of Banking Institutions in Africa: Perceptions of Leading Players Within the Kenyan Banking Industry
Creators: name: Kimani, Danson K.
Publisher: name: The Open University
Year: 2014

description: Following an agency theoretic approach, this study sets out to investigate how banking institutions in Kenya are governed, using primarily semi-structured interview data. The study is incentivised by inadequate research on corporate governance of financial institutions within emerging economies. Accordingly, the study adopts an exploratory research design seeking to understand how governance is perceived and practiced within banks, together with the impact of corporate governance on performance of the Kenyan banking industry. The findings suggest that corporate governance is perceived differently within various banking institutions. It also emerges that corporate governance is practised along four broad lines within banks in Kenya: (a) board governance; (b) influences from global stage; (c) auditing; (d) shareholders. The results also reveal that corporate governance as considered by participants, boosts the performance of the Kenyan banking industry along three performance yardsticks: (a) going concern value; (b) cost-income ratio; (c) return on earnings. The results evidence some differences between the local institutional characteristics and assumptions founding the Anglo-American corporate governance model adopted in Kenya; where banks with concentrated ownership exhibit mainly principal-principal conflicts rather than principal-agent problems. The study recommends two mandatory independent audits - half-year and end-year audits, in order to enhance the corporate governance mechanism of disclosure, and improve governance and financial performance.

description: Over the past few years the world’s agriculture and food systems have become increasingly industrialized with the goal of greater efficiency. Since 2004 scientists and farmers alike have begun to see a decline in bee populations, a phenomenon which has been given the name Colony Collapse Disorder (CCD). At the same time, many scientists and farmers have come to recognize the important role that pollinators such as bees play in our ecosystems and agroecosystems and how the processes of intensification of agriculture (including the use of pesticides, changes in land use and monocropping) are affecting bee populations all over the world. The UBC Farm at the University of British Columbia is home to 7 colonies of honeybees which contribute to the agroecosystem and ecosystem by pollinating both crop plants and wild plants. It has been discovered that one of the best ways to prevent Colony Collapse Disorder is to limit stresses on the hive. The apiculturists and employees at the UBC Farm have assured a good home for the hives, however they have acknowledged that the number of bees is limited by the availability of food for the bees, and therefore it is recommended that the UBC Farm plant crops and plants that would provide more diverse food sources for their honeybees. This report investigates how bees as pollinators in the farm landscape can help the UBC Farm achieve its goals of proving climate-friendly food.
