description: In 2009, the World Bank published a comparative study of cotton sector reforms, based on detailed case studies carried out during 2007/08 in nine of Africa’s main cotton producing countries. The purpose of the study was to draw practical insights from the diversity of experiences in institutional reforms of cotton sectors and to better understand the strengths and weaknesses of the different types of sectors operating in Africa, the likely effects of specific types of policy change, and the possible ways forward. This paper develops a concept note for additional research that would address the perceived weaknesses of the earlier work. The underlying hypothesis of the proposed study is that technology research, farmer training, and policy and institutional reforms to improve cotton sector productivity and incomes tend to be designed for typical or model farmers. This often fails to take into account the diversity among cotton farmers and what this diversity implies for cotton sector development in general and the ability of the cotton sector to contribute to poverty reduction in particular. The proposed research is expected to contribute to aggregate growth in cotton productivity and incomes through the design of more targeted support interventions based on a better understanding of the strategies, capacities, and constraints of the different types of cotton farmers.
Determination of $g$-factor in InAs two-dimensional electron system by capacitance spectroscopy

description: We determine the effective $g$-factor ($|g^\ast|$) of a two-dimensional electron gas (2DEG) using a new method based on capacitance spectroscopy. The capacitance-voltage profile of a 2DEG in an InAs/AlGaSb quantum well measured in an in-plane magnetic field shows a double-step feature that indicates the Zeeman splitting of the subband edge. The method allows for simultaneous and independent determination of $|g^\ast|$ and effective mass $m^\ast$. Data suggest that the biaxial tensile strain in the InAs layer has considerable impacts on both $m^\ast$ and $g^\ast$. Our method provides a means to determine $|g^\ast|$ that is complementary to the commonly used coincidence technique.

Adult learning experiences from an aquarium visit : the on-site and longitudinal roles of personal agendas and social interactions in family groups
Creators: name: Briseño-Garzón, Adriana
Publisher: name: University of British Columbia
Year: 2009

description: The overall and long-lasting impact of learning science from informal situations and environments has been deeply recognised. Also, it has been acknowledged that expanding and deepening our understandings of the nature and dynamics of the learning process in the informal setting is crucial for the development and implementation of rich and enjoyable educational opportunities for all the audiences that visit such settings. This qualitative study investigates how and what the adult members of family groups learn in and from a visit to the Vancouver Aquarium Marine Science Centre, by examining the role of their personal agendas and their social interactions. Using on-site and follow-up open-ended, semi-structured interviews, as well as on-site observations, parents'/guardians' perceptions about their families' experience at the aquarium were analysed. Interpretive data analysis suggests that the adult members of family groups learn as a result of the visit to the aquarium, and that their learning is cognitive, social, and affective in nature. The contact with living creatures elicits emotional responses and connections with past experiences, and promotes cognitive and affective gains in adults, who also gain awareness and understandings about their family members as a result of the collective experience. Also, personal pre-defined and emerging agendas play a significant role in the learning experience at the individual and group levels, both during the visit and longitudinally. Parents/guardians bring mainly recreation, learning and social agendas to the aquarium setting. However, multiple forces influence the construction and continuous negotiation of such dynamic agendas, such as prior experiences, and intrinsic and extrinsic factors. In the long term, adults connect their experience at the aquarium with other relevant contexts such as the home and the work place, and show evidence of long term factual knowledge.

description: This paper extends earlier work by Cox and Durrett, who studied the coalescence times for two lineages in the stepping stone model on the two-dimensional torus. We show that the genealogy of a sample of size n is given by a time change of Kingman's coalescent. With DNA sequence data in mind, we investigate mutation patterns under the infinite sites model, which assumes that each mutation occurs at a new site. Our results suggest that the spatial structure of the human population contributes to the haplotype structure and a slower than expected decay of genetic correlation with distance revealed by recent studies of the human genome.

description: Recent simulations of the formation of the first luminous objects in the universe predict isolated very massive stars to form in dark matter halos with virial temperatures large enough to allow significant amounts of molecular hydrogen to form. We construct a semi-analytic model based on the Press-Schechter formalism and calibrate the minimum halos mass that may form a primordial star with the results from extensive adaptive mesh refinement simulations. The model also includes star formation in objects with virial temperatures in excess of ten thousand Kelvin. The free parameters are tuned to match the optical depth measurements by the WMAP satellite. The models explicitly includes the negative feedback of the destruction of molecular hydrogen by a soft UV background which is computed self-consistently. We predict high redshift supernova rates as one of the most promising tools to test the current scenario of primordial star formation. The supernova rate from primordial stars peaks at redshifts ~20. Using an analytic model for the luminosities of pair-instability supernovae we predict observable magnitudes and discuss possible observational strategies. Such supernovae would release enough metals corresponding to a uniform enrichment to a few hundred thousands of solar metalicity. If some of these stars produce gamma ray bursts our rates will be directly applicable to understanding the anticipated results from the SWIFT satellite. This study highlights the great potential for the James Webb space telescope in probing cosmic structure at redshifts greater than 20.

Majoranas in mixed-valence insulators

Publisher: name: arXiv
Year: 2020
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: A physical model for a mixed-valence impurity in a metal must satisfy the Friedel screening theorem for both valences. Such a model is shown, following earlier work which showed low energy singularities in it, to be supersymmetric, leading to a free Majorana and a phase-shifted Majorana excitation. The theory extended approximately to a lattice of mixed-valence ions at appropriate filling gives, without fine-tuning the parameters, a protected gapless Majorana fermion band across the chemical potential, besides the mixed-valence particle and hole bands separated by gaps. In this situation the system is electrically neutral in linear response but has de Haas-van Alphen oscillations. This is used to explain the recently observed magneto-oscillations in mixed-valence insulators as well as their accompanying low energy thermodynamic and relaxation rate anomalies. Some predictions to test the validity of the theoretical results are provided, the most striking of which is that there should be extensive ground state entropy in such compounds.

description: This paper provides an alternative approach to Duffie and Lando [Econometrica 69 (2001) 633-664] for obtaining a reduced form credit risk model from a structural model. Duffie and Lando obtain a reduced form model by constructing an economy where the market sees the manager's information set plus noise. The noise makes default a surprise to the market. In contrast, we obtain a reduced form model by constructing an economy where the market sees a reduction of the manager's information set. The reduced information makes default a surprise to the market. We provide an explicit formula for the default intensity based on an Azema martingale, and we use excursion theory of Brownian motions to price risky debt.

description: There is a strong trend in this era among most of the developing countries towards economic liberalization and free market application. Egypt is a representative country as a case study that has passed several steps towards this direction. Such trend has impacts on the household welfare during the transition period of transformation, particularly on food consumption and, in turn, on the dietary adequacy of the low income people. It was found that such movements of free price food will cause a deficiency in protein quality (net protein utilized). Such deficiency will be harmful to vulnerable groups whom are going to be productive adults in the future. From the sustainable development view, it is important to secure adequate protein of good quality for those groups, till the economic growth due to liberalization reaches the level enough to make the low income households able to purchase the adequate protein of better food commodities such as milk and eggs or fish.

description: We constructed a Hubble Space Telescope (HST) astro-photometric catalog of the central region of the Galactic globular cluster NGC 1261. This catalog, complemented with Gaia DR2 data sampling the external regions, has been used to estimate the structural parameters of the system (i.e., core, half-mass, tidal radii and concentration) from its resolved star density profile. We computed high-precision proper motions thanks to multi-epoch HST data and derived the cluster velocity dispersion profile in the plane of the sky for the innermost region, finding that the system is isotropic. The combination with line-of-sight information collected from spectroscopy in the external regions provided us with the cluster velocity dispersion profile along the entire radial extension. We also measured the absolute proper motion of NGC 1261 using a few background galaxies as a reference. The radial distribution of the Blue Straggler Star population shows that the cluster is in a low/intermediate phase of dynamical evolution.

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.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

description: Bidirectional nanoantennas are of key relevance for advanced functionalities to be implemented at the nanoscale, and in particular for color routing in an ultracompact flat-optics configuration. Here we demonstrate a novel approach avoiding complex collective geometries and/or restrictive morphological parameters, based on cross-polarized detuned plasmonic nanoantennas in a uniaxial (quasi-1D) bimetallic configuration. The nanofabrication of such a flat-optics system is controlled over a large-area (cm^2) by a novel self-organized technique exploiting ion-induced nanoscale wrinkling instability on glass templates to engineer tilted bimetallic nanostrip dimers. These nanoantennas feature broadband color routing with superior light scattering directivity figures, which are well described by numerical simulations and turn out to be competitive with the response of lithographic nanoantennas. These results demonstrate that our large-area self-organized metasurfaces can be implemented in real world applications of flat optics color routing from telecom photonics to optical nanosensing.

A narrative inquiry into cultural identity construction of young Korean Canadians : "my cultural identity is a production I create from different cultural pieces"
Creators: name: Park, Minjeong
Publisher: name: University of British Columbia
Year: 2009

description: This study investigates how young Korean Canadians construct and re-construct their cultural identity through cross-cultural experiences as they interact with and negotiate cultural differences. My interest in this study was triggered by conversations with some young Korean Canadians. Prior to these conversations, I assumed that they would be more Canadian than Korean in terms of culture. It was a surprise to learn that they were becoming more interested in Korean culture as they grew up and gained a sense of their identity as Korean Canadian. I was especially surprised when I considered their having grown up in Canadian contexts where they speak English fluently and are exposed to Canadian culture most of the time. In this study, I conducted a narrative inquiry which enabled me to uncover unrecognized and unspoken experiences associated with the cross-cultural experiences of young Korean Canadians and understand identity construction as a temporally and relationally multilayered process. The analysis presented in this study was drawn from twenty-six openended interviews with young Korean Canadians living in Vancouver, British Columbia. My findings showed that the young Korean Canadians were not indefinitely torn between cultures nor did they remain victims of unending identity crisis, although during the initial stage of adaptation, they went through uncertainties, tensions, and anxieties about not being wholly one identity or the other. While crossing cultural boundaries and re-configuring different cultures from inside-out and outside-in perspectives, they became more able to assess which elements of each culture they wanted to embrace in their own identity construction. As they transformed their approach from "fitting in one place" to "mixing and matching different cultural elements," they were awakened to the possibilities of having a multicultural identity. Identifying multiple cultural elements, they re-constructed their own emergent form of identity beyond the limited boundary of Korean culture or Canadian culture. This study invites educators to revision cultural identity of immigrants, fabricated by crosscultural living, as productive tensions and generative possibilities rather than problems to be adjusted and resolved.

description: Energy, agriculture, and GHG emissions are highly interrelated. Several agricultural commodities are currently used as feedstock for biofuel production to replace fossil fuels. As the largest consumer of energy, the U.S. has taken several initiatives to reduce the use of fossil fuels, achieve energy security, and reduce GHG emissions. The industrial community of the U.S. invested heavily in biofuel and wind energy production. North Dakota has highest potential in producing wind energy and biomass from dedicated energy crops. Unfortunately these resources are not fully utilized for producing renewable energy. North Dakota is an energy intensive economy and per capita energy consumption is higher than other states. This technical bulletin provides a comprehensive report on the energy production and related emissions in the United States with special emphasis on North Dakota. The bulletin also discusses various alternative methods to reduce GHG emissions to meet the regulatory standards with a special emphasis on North Dakota. The study found that North Dakota produces the cheapest electricity and a major share is consumed outside the state. The price of electricity does not include negative externalities associated with burning lignite coal. North Dakota uses its potential to produce wind and corn ethanol to a great extent. The state level policies and financial supports are directed to wind industry and energy efficiency measures. The current renewable portfolio standards and non-compliance adversely affect the renewable energy industry in North Dakota.

description: Using an angular momentum projected single particle basis, a pnQRPA approach is used to study the $2νββ$ properties of ten isotopes, exhibiting various quadrupole deformations. The mother and daughter nuclei exhibit different quadrupole deformations. Since the projected basis enables a unified description of deformed and spherical nuclei, situations where the nuclei involved in the double beta decay process are both spherical, both deformed or one spherical and another deformed, can be treated through a sole formalism. Dependence of single $β^-$ and $β^+$ strength distribution on atomic mass number and nuclear deformation is analyzed. For the double beta decay process, the Gamow-Teller transition amplitudes and half lives are calculated. Results are compared with the experimental data as well as with the predictions of other theoretical approaches. The agreement between the present results and experimental data is fairly good.

description: Les questions que nous avons posées à quarante parents autochtones dont les enfants avaient été pris en charge par la Société d'aide à l'enfance (SAE) entre 2000 et 2018 se situaient sur deux axes : 1) la manière dont l'intervention de la SAE prenait en compte la difficulté d'être à la fois parent et autochtone dans un contexte traumatique colonial et 2) la façon dont les cultures autochtones étaient ou non intégrées dans le processus de réajustement parental qu'entreprend la SAE. Pour aborder ces deux axes, nous sommes partie du principe que les Indigenous Studies constituaient un cadre à la fois incontournable et indépassable pour étudier toute une série de thématiques liées au domaine institutionnel de la protection de l'enfance : définition de la famille, approche de la parentalité, conception de l'intérêt de l'enfant, hiérarchie des savoirs et de leurs valeurs respectives, régulation de la précarité, etc. Malgré diverses stratégies de diversification, nous avons eu devant nous quarante expériences quasi similaires en ce qu'elles témoignaient toutes d'une impossibilité pour les parents d'être reconnus institutionnellement comme partie prenante de décisions impliquant pourtant directement leurs propres enfants. Faisant fi de l'histoire coloniale et de ses diverses conséquences désastreuses notamment sur les plans affectif, parental et économique, les intervenants apparaissent pris dans une socialisation professionnelle qui ne reconnait ni le contexte (colonial), ni leurs cultures, ni leurs points de vue, ni leurs souffrances. Pas plus que leurs efforts pour (enfin) devenir des parents. Faisant comme si rien ne s'était passé, les intervenants de la SAE imposent alors aux parents des décisions aussi absurdes qu'injustes comme seule possibilité de gagner leurs galons de bon parent. Mais l'analyse montre encore autre chose : il ne s'agirait en effet pas seulement pour les parents de se désoler du fait que les intervenants perdent de vue ce qu'être un parent aux multiples vulnérabilités veut dire. Il ne leur serait pas seulement demandé de penser, d'agir et de réagir comme un parent blanc. Leur serait également communiquée, dans une forme d'injonction contradictoire, l'impossibilité de remplir le statut et le rôle que le SAE leur demande pourtant d'endosser.

description: Cosmological analyses of galaxy surveys rely on knowledge of the redshift distribution of their galaxy sample. This is usually derived from a spectroscopic and/or many-band photometric calibrator survey of a small patch of sky. The uncertainties in the redshift distribution of the calibrator sample include a contribution from shot noise, or Poisson sampling errors, but, given the small volume they probe, they are dominated by sample variance introduced by large-scale structures. Redshift uncertainties have been shown to constitute one of the leading contributions to systematic uncertainties in cosmological inferences from weak lensing and galaxy clustering, and hence they must be propagated through the analyses. In this work, we study the effects of sample variance on small-area redshift surveys, from theory to simulations to the COSMOS2015 data set. We present a three-step Dirichlet method of resampling a given survey-based redshift calibration distribution to enable the propagation of both shot noise and sample variance uncertainties. The method can accommodate different levels of prior confidence on different redshift sources. This method can be applied to any calibration sample with known redshifts and phenotypes (i.e. cells in a self-organizing map, or some other way of discretizing photometric space), and provides a simple way of propagating prior redshift uncertainties into cosmological analyses. As a worked example, we apply the full scheme to the COSMOS2015 data set, for which we also present a new, principled SOM algorithm designed to handle noisy photometric data. We make available a catalog of the resulting resamplings of the COSMOS2015 galaxies.

description: We developed an exact analytical treatment for space-charge waves within a relativistic electron beam in terms of (self-reproducing) propagating eigenmodes. This result is of obvious theoretical relevance as it constitutes one of the few exact solution for the evolution of charged particles under the action of self-interactions. It also has clear numerical applications in particle accelerator physics where it can be used as the first self-consistent benchmark for space-charge simulation programs. Today our work is of practical relevance in FEL technology in relation with all those schemes where an optically modulated electron beam is needed and with the study of longitudinal space-charge instabilities in magnetic bunch compressors.

We also show an alternative route to deduce these two conjectures from Milne's determinant formulas for sums of $4s^2$, respectively $4s(s+1)$, triangular numbers. This approach is inspired by Zagier's proof of the Kac--Wakimoto formulas via modular forms. We end the survey with recent conjectures of the first author and Chua.

We study the action of Poisson algebras of admissible functions on P on various spaces of locally (with respect to P) defined functions on Q, via hamiltonian vector fields. Finally, guided by examples arising in complex analysis and contact geometry, we propose an extension of the notion of prequantization in which the action of U(1) on Q is permitted to have some fixed points.

description: We investigate the strategic pricing for leading brands sold in the carbonated soft drink (CSD) market in the context of a flexible demand specification (i.e. random parameter nested logit) and a structural pricing equation. Our approach does not rely upon the often used ad hoc linear approximations to demand and profit-maximizing first-order conditions. We estimate the structural pricing equation using four different estimators (i.e. OLS, LIML, 2SLS, and GMM) and compare the implied deviation from Bertrand-Nash competition. Our results suggest that retailers, on average, price CSD brands below their cost, likely a result of the competitive retailing environment. We also find CSD wholesalers price their brands significantly more cooperatively than Bertrand-Nash would suggest, thus inflating profits.
Renewing aboriginal education through relationship and community
Creators: name: Firman, Brenda
Publisher: name: University of British Columbia
Year: 2009

description: The brokenness of Aboriginal communities, families, and individuals in Canada is well documented in reports and statistics and publicized in sensationalized news reports. The more nurturing aspects of Aboriginal life are shared with and often appropriated by the dominant culture. It seems that the damaging effects of colonization are the responsibility of today's Aboriginal people while the settler society is free to profit emotionally, spiritually, physically, mentally and financially from the cultural practices and Indigenous knowledge that have survived colonization. The Canadian government's investigation into relationship between the settler society and Aboriginal peoples in Canada - the Royal Commission on Aboriginal Peoples - clearly identified the responsibility of non-Aboriginal Canadians in the history, current conditions, and future possibilities for Aboriginal peoples in Canada. Unfortunately, this responsibility is not well known, understood, accepted, or acted upon within the policies and practices of education for Aboriginal peoples. This narrative documents the journey of one non- Aboriginal educator in relationship with Aboriginal peoples and with her dominant culture. Believing both that trust is required for systemic and lasting change and that trust requires intimacy (Roybal Rose, 1995), the author presents a very personal and intimate understanding of the historical and ongoing relationship between Aboriginal and non-Aboriginal peoples in Canada as a means of encouraging the active and informed involvement of each reader in transformative efforts in the renewing of Aboriginal education.

description: Spending on political advertising increases with every election cycle, not only for congressional or presidential candidates, but also for state-level ballot initiatives. There is little research in marketing, however, on the effectiveness of political advertising at this level. In this study, we conduct an experimental analysis of advertisements used during the 2008 campaign to mandate new animal welfare standards in California (Proposition 2). Using subjects' willingness to pay for cage-free eggs as a proxy for their likely voting behavior, we investigate whether advertising provides real information to likely voters, and thus sharpens their existing attitudes toward the issue, or whether advertising can indeed change preferences. We find that advertising in support of Proposition 2 was more effective in raising subjects' willingness to pay for cage-free eggs than ads in opposition were in reducing it, but we also find that ads in support of the measure reduce the dispersion of preferences and thus polarize attitudes toward the initiative. More generally, political ads are found to contain considerably more "hype" than "real information" in the sense of Johnson and Myatt (2006).
Mechanisms for QoE optimisation of Video Traffic: A review paper

description: Transmission of video traffic over the Internet has grown exponentially in the past few years with no sign of waning. This increasing demand for video services has changed user expectation of quality. Various mechanisms have been proposed to optimise the Quality of Experience (QoE) of end users video. Studying these approaches are necessary for new methods to be proposed or combination of existing ones to be tailored. We discuss challenges facing the optimisation of QoE for video traffic in this paper. It surveys and classifies these mechanisms based on their functions. The limitation of each of them is identified and future directions are highlighted.

description: This study presents survey results of the public's willingness to get vaccinated against COVID-19 during an early phase of the pandemic and examines factors that could influence vaccine acceptance based on a between-subjects design. A representative quota sample of 572 adults in the US and UK participated in an online survey. First, the participants' medical use tendencies and initial vaccine acceptance were assessed; then, short vignettes were provided to evaluate their changes in attitude towards COVID-19 vaccines. For data analysis, ANOVA and post hoc pairwise comparisons were used. The participants were more reluctant to vaccinate their children than themselves and the elderly. The use of artificial intelligence (AI) in vaccine development did not influence vaccine acceptance. Vignettes that explicitly stated the high effectiveness of vaccines led to an increase in vaccine acceptance. Our study suggests public policies emphasizing the vaccine effectiveness against the virus could lead to higher vaccination rates. We also discuss the public's expectations of governments concerning vaccine safety and present a series of implications based on our findings.

description: A study destined to characterize the fresh markets channel for vegetable products distribution in the metropolitan area of Chile was carried out. The places where the exhibitors get the fruits and vegetables were identified; the supply forms by type of supplier of the exhibitors were studied, specifically purchasing prices, types of payment and frequency of supply for fruits and vegetables. Furthermore, a comparison of prices at a retailer level in fruits, vegetables and potatoes was done. According to the above mentioned, the total of fresh markets and its places of the Metropolitan Region was surveyed. Main results show the fresh markets as a relevant agent in the supplying of the population and the commercialization for the rural production, where food products considered healthy and bought in a high percentage to small producers are sold. A difference between selling prices in fresh markets and supermarkets in the topics studied was found.

description: Using symplectic topology and the Radon transform, we prove that smooth 4-dimensional projective planes are diffeomorphic to $\mathbb{CP}^2$. We define the notion of a plane curve in a smooth projective plane, show that plane curves in high dimensional regular planes are lines, prove that homeomorphisms preserving plane curves are smooth collineations, and prove a variety of results analogous to the theory of classical projective planes.

Magnetic helicity in plasma of chiral fermions electroweakly interacting with inhomogeneous matter

description: We study chiral fermions electroweakly interacting with a background matter having the nonuniform density and the velocity arbitrarily depending on coordinates. The dynamics of this system is described approximately by finding the Berry phase. The effective action and the kinetic equations for right and left particles are derived. In the case of a rotating matter, we obtain the correction to the anomalous electric current and to the Adler anomaly. Then we study some astrophysical applications. Assuming that the chiral imbalance in a rotating neutron star vanishes, we obtain the rate of the magnetic helicity change owing to the interaction of chiral electrons with background neutrons. The characteristic time of the helicity change turns out to coincide with the period of the magnetic cycle of some pulsars.
