Revealing social dimensions of open space cultivation by older women in Harare : advancing a social planning discourse for UA
Creators: name: Gabel, Stephanie
Publisher: name: University of British Columbia
Year: 2009

description: This research on urban agriculture in Harare, Zimbabwe highlights women's ideas, needs, concerns and agency, contextualising these findings through an investigation of the institutional and policy environment governing the practice of open space cultivation in the city. A feminist methodology provides an overall framework, while also incorporating ethnomethodology and participatory research methodologies to highlight the broader social, political and cultural contexts of urban agriculture. A multimethod approach was adopted that included the use of semi-structured interviewing, focus groups, strategic meetings, participatory methods, visioning interviews and action methods (such as field trips, creating a stakeholder forum, and organising income generating projects). Findings from this research have been used to develop a gender-aware history of women and urban agriculture (UA) in Harare. Key findings show that the forms of organisation for open space cultivation (SOSC) developed by older women have been historically unacknowledged, ignored, and impeded by those with decision making power, most often male elites. Nine legal channels available for SOSC in Harare are uncovered in the research, dispelling the myth that UA is an illegal activity in the City. This research further elaborates on the impacts of legal ambiguity that have resulted in conflicts between various land tenure systems and categories, demonstrating the serious governance challenges at the heart of developing supportive policy development for UA in the City. The voices of women are used to illuminate the dire need for local and neighbourhood level leadership, and the importance of addressing the cultural context in which UA is imbedded. A discussion of planning and governance in Harare reveals the exclusionary practices that operate to make the work of women, their UA and land based livelihoods invisible in planning practice and city decision making. The research shows the potential for shifting planning practice and discourse toward more people centred, democratic forms of planning for UA.

description: Despite the well-known idea that rice is a commodity and thus it is unlikely to be differentiated, there is a large number of rice products available in the retail market, with different classification, standards, packages, brands etc. It can be observed significant variation in their prices, considering the brands, manufacturers, stores and also when the same product is considered in a short interval of time. Before these findings, we asked what the effects of rice purchasing strategies are over consumers’ expenditures. This paper proposes a mathematical model to simulate the decision process of rice purchasing by consumers with different preferences, in front of products available in supermarkets in a city of Sao Paulo state and another in Rio Grande do Sul state (Brazil).

description: This study analyses the Brazilian beef exportation potential considering the supposition of future agreements of regional integration. The countries or blocks that were chosen are The European Union (EU), the North American Free Trade Agreement (NAFTA) countries, the Commonwealth of Independent States, the Popular Republic of China (PRC) and Japan. To analyze the meat sector exportation potential, four methodological generalizations are developed: the importing potential of the mentioned countries, the calculus of the evolution in the Revealed Advantage Index of Brazilian exportations and its main competitors, bibliographical research of the main existing trade barriers and the calculus of the Regional Orientation Index. The results concerning the importing potential indicate that the European Union (EU) consists of a very attractive market to Brazilian beef. The results of the calculus of comparative advantages reveal that Brazil has a higher competitivity in meat sector and it increasing in the period between 1990 and 2003. When considering the competitors inside each block or country, the European Union shows up as the major competitor. As far as the imposed trade barriers, these come out, in a general way, as extremely high and sometimes representing a blockage. Thus, the Brazilian meat sector would be largely improved if these barriers were eliminated. Finally, on the last relation, we can verify the high level of acceptance of Brazilian beef exportation to those blocks that do not have impeditive sanitary barriers. Nevertheless, when crossing the results obtained to the sector one can observe that from the accomplishment of inter-regional free trade agreements, via Mercosur or through bilateral agreements with the blocks or countries considered in this study, would bring real profits to the Brazilian meat sector.
Contribution of RasGRP1 to BCR-induced deletion in the immature B cell line WEHI 231
Creators: name: Guilbault, Benoit
Publisher: name: University of British Columbia
Year: 2009

description: RasGRP1 is a guanine nucleotide exchange factor (GEF) that activates Ras GTPases downstream of the B and T lymphocyte antigen receptors. RasGRP1 is a critical regulator of T cell homeostasis, and contributes to the maintenance of T cell-mediated tolerance in the host. Although Ras signalling is important during B cell development, relatively little is known about a role for RasGRP1 in B cells, or its contribution to B cell receptor (BCR) signalling. RasGRP1 expression is detected in the bone marrow and some B cell lines including the murine immature B cell line WEHI 231. The WEHI 231 cell line, which mimics immature B cell responses to self-antigen by undergoing cell cycle arrest and apoptosis in response to antigen stimulation, was used to determine whether RasGRP1 has the ability to modulate BCR-mediated responses in B cells. WEHI 231 cell populations with increased RasGRP1 expression (RasGRP1high cells) were generated by retroviral transduction. A two-fold increase in RasGRP1 protein levels correlated with increased Ras activity. A three-fold increase in the fraction of cells undergoing apoptosis was detected in RasGRP1high cells following BCR ligation, compared with control cells. Mutation of the GEF domain of RasGRP1, which is required for Ras activation, prevented the protein from sensitizing WEHI 231 cells to BCR-induced apoptosis. Expression of constitutively active Ras GTPases was sufficient to sensitize WEHI 231 cells to BCR-induced apoptosis. These results suggest that RasGRP1 acts as a positive regulator of BCR signalling, and has the ability to sensitize WEHI 231 cells to BCR-induced apoptosis via activation of Ras GTPases. Although increased RasGRP1 expression caused sustained activation of the Ras effectors ERK1/2, this effect was not required for the ability of RasGRP1 to sensitize WEHI 231 cells to BCR-induced apoptosis. Instead, increased RasGRP1 expression was found to inhibit the NF-KB pathway, a critical regulator of life and death decisions in WEHI 231 cells. While stimuli that activate NF-κB prevented increased BCR-induced apoptosis of RasGRP1high cells, inhibition of NF-κB was sufficient to sensitize WEHI 231 cells to BCR-induced apoptosis. These results suggest that RasGRP1 sensitizes WEHI 231 cells to BCR-induced apoptosis by causing down-regulation of the NF-κB pathway.

description: This paper analyses the possible impacts of tariffs and nontariffs barriers elimination on beef market in Brazil. To evaluate the effects of free trade is used a spatial model formulated as Mixed Complementary Problem (MCP). We simulate four sceneries to achieve this purpose : the first simulates the elimination of all trade barriers in a multilateral scope; the second simulates the free trade area creation between Mercosur and EU countries. The third simulates the free trade area formation between the America countries (FTAA); and the fourth considers the elimination of Foot and Mouth Disease in Mercosur countries. In the beef market it is not enough eliminate the tariffs barriers to stimulate the beef production and exportation in Brazil. The major gains occurs in sceneries where is eliminated the non-tariffs barriers.

description: No known analytic framework precisely explains all the phenomena observed in jamming. The replica theory for glass and jamming is a mean field theory which attempts to do so by working in the limit of infinite dimensions, such that correlations between neighbors are negligible. As such, results from this mean field theory are not guaranteed to be observed in finite dimensions. However, many results in mean field for jamming have been shown to be exact or nearly exact in low dimensions. This suggests that the infinite dimensional limit is not necessary to obtain these results. In this paper, we perform precision measurements of jamming scaling relationships between pressure, excess packing fraction, and number of excess contacts from dimensions 2-10 in order to extract the prefactors to these scalings. While these prefactors should be highly sensitive to finite dimensional corrections, we find the mean field predictions for these prefactors to be exact in low dimensions. Thus the mean field approximation is not necessary for deriving these prefactors. We present an exact, first principles derivation for one, leaving the other as an open question.

description: This article investigates the potential gains to the U.S. meat sector with the implantation of the U.S. National Animal Identification System (NAIS). The focus is on the effect that the NAIS could have on consumers’ risk perception about eating meat. System of demand equations are estimated using time series of food safety indexes variables used as proxies for consumers’ reactions to news on meat safety issues. The series of food safety indexes are built on the basis of the number of food safety news reported in top U.S. newspapers. Using the preferred model estimates, three scenarios are constructed in order to account for the cases wherein the NAIS is not implemented, is implemented only for beef and is implemented for beef and pork. The differences in the estimated total revenues for each scenario are used as a gross measure of the NAIS benefit for each type of meat. The main conclusion is that the gains for the beef and pork sectors would be capable of covering the costs of the NAIS implementation. However, this result depends on how much of these potential gains will arrive at primary producers.

description: Coulomb attraction between electrons and holes in a narrow-gap semiconductor or a semimetal is predicted to lead to an elusive phase of matter dubbed 'excitonic insulator'. However, direct observation of such electronic instability remains extremely rare. Here, we report the observation of incipient divergence in the static excitonic susceptibility of the candidate material Ta2NiSe5 using Raman spectroscopy. Critical fluctuations of the excitonic order parameter give rise to quasi-elastic scattering of B2g symmetry, whose intensity grows inversely with temperature toward the Weiss temperature of Tw ~241 K, which is arrested by a structural phase transition driven by an acoustic phonon of the same symmetry at Tc =325 K. Concurrently, a B2g optical phonon becomes heavily damped to the extent that its trace is almost invisible around Tc, which manifests a strong electron-phonon coupling that has obscured the identification of the low-temperature phase as an excitonic insulator for more than a decade. Our result unambiguously reveals the electronic origin of the phase transition.

description: We report new results from the Cryogenic Dark Matter Search (CDMS II) at the Soudan Underground Laboratory. Two towers, each consisting of six detectors, were operated for 74.5 live days, giving spectrum-weighted exposures of 34 kg-d for germanium and 12 kg-d for silicon targets after cuts, averaged over recoil energies 10-100 keV for a WIMP mass of 60 GeV. A blind analysis was conducted, incorporating improved techniques for rejecting surface events. No WIMP signal exceeding expected backgrounds was observed. When combined with our previous results from Soudan, the 90% C.L. upper limit on the spin-independent WIMP-nucleon cross section is 1.6 x 10^{-43} cm^2 from Ge, and 3 x 10^{-42} cm^2 from Si, for a WIMP mass of 60 GeV. The combined limit from Ge (Si) is a factor of 2.5 (10) lower than our previous results, and constrains predictions of supersymmetric models.

description: In QCD at high density, the color-octet quark-antiquark condensate $\langle\overlineψγ_0(λ^A)_C (λ^A)_Fψ\rangle$ is generally nonzero and dynamically breaks the $\mathrm{SU}(3)_C\times \mathrm{SU}(3)_L\times\mathrm{SU}(3)_R$ symmetry down to the diagonal $\mathrm{SU}(3)_V$. We evaluate this condensate in the mean-field approximation and find that it is of order $μΔ^2\log(μ/Δ)$ where $Δ$ is the BCS gap of quarks. Next we propose a novel non-Hermitian chiral random matrix theory that describes the formation of colorful quark-antiquark condensates. We take the microscopic large-$N$ limit and find that three phases appear depending on the parameter of the model. They are the color-flavor locked phase, the polar phase, and the normal phase. We rigorously derive the effective theory of Nambu-Goldstone modes and determine the quark-mass dependence of the partition function.

description: The article analyzes and discusses the privatization of the rural extension services according to international literature. To start with, the subject is set in the horizon of the debate of the so called State Reform, which determined the agenda for the development since the 1980’s. Next, we show how the subject has been treated so far having the economic theory as background and we examine experiments of privatization at international level. The analysis of such experiments reveals that the early agenda for the privatization took for granted that the rural extension services − which were a responsibility of the State − would be held completely by the private sectors. However, a series of obstacles appeared and arguments for models of privatization in which the State has a main role spread over. Therefore, the exam of international experiments of privatization led to the conclusion that they followed different orientations. One set of experiments was oriented by the notion of the “Minimum State” while the other had for reference the State as a supporter for private action. The privatization is a current and relevant process and, therefore, the discussion about it is considered necessary.

description: Hearing impairment is a prevalent problem that comes with many daily life challenges. These challenges, mainly in the areas of speech intelligibility and sound localisation, can have consequences ranging from social isolation to physical danger. Even though current hearing aid technology can partly alleviate these issues, in practice many acoustic scenes are still challenging. One of the shortcomings of spatial filtering in hearing aids is that speech intelligibility is often not optimised for directly, as that is a subjective measure and more difficult to quantify. Instead, most developed beamformers focus on maximising the speech-to-noise-plus-interference ratio (SNIR), which is only one factor that influences intelligibility. The psychoacoustic effect known as spatial release from masking (SRM) is usually not considered, but can also be a dominant factor.

In this paper, a signal model is developed that explicitly takes SRM into account in the beamforming design. This is achieved by transforming the binaural intelligibility prediction model developed by Beutelmann and Brand (2006, JASA 120:331) to a signal processing framework. The main phase of this model, the equalisation–cancellation (EC) phase, can be represented as an internal beamformer that accounts for the spatial filtering of the auditory system. Internal masking noise is added to the hearing aid signals to model hearing thresholds, which is used to personalise the model. When concatenated with a typical beamformer signal model, the output of this extended model can be used to analyse existing beamformers and design new beamformers one step closer to how the auditory system perceives binaural sound.

It can mathematically be shown that the binaural minimum variance distortionless response (BMVDR) beamformer, which is known to be optimal in maximising the SNIR of the beamformer signals, is also an optimal solution for the extended, perceived model. This seems to suggest that SRM does not play a significant role in improving intelligibility after optimal beamforming is already performed. What is different compared to the classic case, however, is that the solution is no longer unique; the solution space has a number of degrees of freedom dependent on the number of microphones in the hearing aids. These degrees of freedom can be used to preserve binaural cues of interferent sources, while still achieving the same perceived performance of the BMVDR beamformer. The proposed beamformer might in practice be sensitive to intelligibility model mismatch errors, and the practical performance needs to be studied in more detail.

description: Recently, Generative Adversarial Networks (GANs)} have been widely used for portrait image generation. However, in the latent space learned by GANs, different attributes, such as pose, shape, and texture style, are generally entangled, making the explicit control of specific attributes difficult. To address this issue, we propose a SofGAN image generator to decouple the latent space of portraits into two subspaces: a geometry space and a texture space. The latent codes sampled from the two subspaces are fed to two network branches separately, one to generate the 3D geometry of portraits with canonical pose, and the other to generate textures. The aligned 3D geometries also come with semantic part segmentation, encoded as a semantic occupancy field (SOF). The SOF allows the rendering of consistent 2D semantic segmentation maps at arbitrary views, which are then fused with the generated texture maps and stylized to a portrait photo using our semantic instance-wise (SIW) module. Through extensive experiments, we show that our system can generate high quality portrait images with independently controllable geometry and texture attributes. The method also generalizes well in various applications such as appearance-consistent facial animation and dynamic styling.

description: We explore the causal effect of market-oriented pension reform on net foreign direct investment (FDI) inflows in Latin America, which has experienced a wave of pension privatization and FDI in the last two decades. With our balanced panel of 17 countries over the 1991-2006 period, we implement fixed effects models, controlling for the endogenous decision to enacted full or partial privatization of the public pension system and several other covariates whose choice is informed by the rich empirical literature on FDI. Our econometric results indicate that privatization triggers a significant increase in net FDI inflows within a year of reform implementation and that the effect does not wane over time. We estimate that privatization increases FDI as a percentage of GDP by between 41 and 47%, ceteris paribus.

description: Decoupled payments were thought to have minimal impacts on current production decisions and input use. However, the literature has identified several mechanisms through which decoupled payments become coupled. We analyze the effects of uncertainty regarding future policy changes on farm-level production decisions and input use, focusing on farmers’ expectations of base acreage and yield updating. Using farm-level data, we find positive relationships between both decoupled and other government payments and real per acre expenditures on agricultural chemicals. Furthermore, there is evidence that decoupled payments may affect the intensive margin more than other government payments.

description: We demonstrate a new type of transition within the strong coupling regime, which alters the coupling mechanism in multimode cavities. We show that this transition drastically modifies the Hamiltonian describing the polaritons, such that different cavity modes are either entangled via the material or completely decoupled. This decoupling transition occurs due to the competition between the dissipation in the material and the finite group velocity, which governs the propagation of information across the cavity and among the molecules. The results indicate that the velocity of light, which is often not taken into account in cavity quantum electrodynamics, plays a crucial role in the formation of cavity polaritons and their dynamics.

description: Starting with a finite point set $X \subset \mathbf{R}^d$, the peeling process repeatedly removes the set of the vertices of the convex hull of the current set. The number of peeling steps required to completely remove $X$ is called the layer number of $X$, denoted by $L(X)$. In the article, we study the layer number of evenly distributed families of point sets contained in $B^d$, the $d$-dimensional unit ball. These sets consist of points in $B^d$ whose minimal distance is asymptotically as large as possible. We show that for a set $X$ belonging to an evenly distributed family, $L(X) \geq Ω(|X|^{1/d})$ holds, with the bound being asymptotically sharp. On the other hand, building on earlier results, we prove that $L(X)\leq O(|X|^{2/d})$ holds for $d\geq 2$, which improves greatly on the current upper bound of $O(|X|^{(d+1)/2d})$ for $d \geq 3$. Finally, we provide a recursive construction of evenly distributed families whose sets satisfy $L(X) = Θ(|X|^{2/d - 1/(d 2^{d-1})})$, showing that our upper bound is nearly tight.

description: We examine policy implications of including rural viability to the notion of multifunctional agriculture. We assume that rural viability refers predominantly to the number of people living in rural areas to keep the infrastructure and living conditions at good state for a good life. The economic core of viability is employment in agriculture and agriculture serving sectors. Viability benefits are modelled with the help of a viability valuation function. We demonstrate that rural viability entails adjusting fertilizer tax and buffer strip subsidy below their environmental first-best Pigouvian levels to reflect the direct and indirect employment effects of agricultural production. Moreover, when non-agricultural land use is present, an additional, non-agricultural instrument is needed to adjust the amount of land allocated to agriculture to its socially optimal level. Thus, inclusion of rural viability creates distortions in multifunctional policies. Theoretical results are illustrated with Finnish data to examine how the inclusion of rural viability to multifunctionality relates to the true socially optimal agri-environmental multifunctionality. We also assess welfare loss from promoting rural viability in the case where there is no base on viability benefits.

description: Recently experiments have shown very significant spin activity in biological molecules such as DNA, proteins, oligopeptides and aminoacids. Such molecules have in common their chiral structure, time reversal symmetry and the absence of magnetic exchange interactions. The spin activity is then assumed to be due to either the pure Spin-orbit (SO) interaction or SO coupled to the presence of strong local sources of electric fields. Here we derive an analytical tight-binding Hamiltonian model for Oligopeptides that contemplates both intrinsic SO and Rashba interaction induced by hydrogen bond. We use a lowest order perturbation theory band folding scheme and derive the reciprocal space intrinsic and Rashba type Hamiltonian terms to evaluate the spin activity of the oligopeptide and its dependence of molecule uniaxial deformations. SO strengths in the tens of meV are found and explicit spin active deformation potentials. We find a rich interplay between responses to deformations both to enhance and diminish SO strength that allow for experimental testing of the orbital model. Qualitative consistency with recent experiments shows the role of hydrogen bonding in spin activity.

description: Learning to understand and infer object functionalities is an important step towards robust visual intelligence. Significant research efforts have recently focused on segmenting the object parts that enable specific types of human-object interaction, the so-called "object affordances". However, most works treat it as a static semantic segmentation problem, focusing solely on object appearance and relying on strong supervision and object detection. In this paper, we propose a novel approach that exploits the spatio-temporal nature of human-object interaction for affordance segmentation. In particular, we design an autoencoder that is trained using ground-truth labels of only the last frame of the sequence, and is able to infer pixel-wise affordance labels in both videos and static images. Our model surpasses the need for object labels and bounding boxes by using a soft-attention mechanism that enables the implicit localization of the interaction hotspot. For evaluation purposes, we introduce the SOR3D-AFF corpus, which consists of human-object interaction sequences and supports 9 types of affordances in terms of pixel-wise annotation, covering typical manipulations of tool-like objects. We show that our model achieves competitive results compared to strongly supervised methods on SOR3D-AFF, while being able to predict affordances for similar unseen objects in two affordance image-only datasets.

description: We describe a new aerogel threshold Cherenkov detector installed in the HMS spectrometer in Hall C at Jefferson Lab. The Hall C experimental program in 2003 required an improved particle identification system for better identification of pi/K/P, which was achieved by installing an additional threshold Cherenkov counter. Two types of aerogel with n=1.03 and n=1.015 allow one to reach 10^{-3} proton and 10^{-2} kaon rejection in the 1-5 GeV/c momentum range with pion detection efficiency better than 99% (97%). The detector response shows no significant position dependence due to a diffuse light collection technique. The diffusion box was equipped with 16 Photonis XP4572 PMT's. The mean number of photoelectrons in saturation was ~16 and ~8, respectively. Moderate particle identification is feasible near threshold.

description: This paper analyzes the relationships between bilateral trade and economic growth in the U.S. and Korean economies. Using quarterly data from 1990 to 2008, the theoretical procedures utilize Ordinary Least Square (OLS) and Seemingly Unrelated Regression (SUR) models under the static model assumption, an Impulse Response Function (IRF) and Forecast Error Variation Decomposition (FEVD) under the Vector Autoregressive (VAR) model, and Granger causality tests. Empirical results indicate a causal relationship between bilateral export growth and economic growth for the U.S. and Korean economies. The export-led growth (ELG) hypothesis is strongly supported by the results of Granger causality tests on Korean exports.
Subwavelength atom localization via amplitude and phase control of the absorption spectrum-II

description: Interaction of the internal states of an atom with spatially dependent standing-wave cavity field can impart position information of the atom passing through it leading to subwavelength atom localization. We recently demonstrated a new regime of atom localization [Sahrai {\it et al.}, Phys. Rev. A {\bf 72}, 013820 (2005)], namely sub-half-wavelength localization through phase control of electromagnetically induced transparency. This regime corresponds to extreme localization of atoms within a chosen half-wavelength region of the standing-wave cavity field. Here we present further investigation of the simplified model considered earlier and show interesting features of the proposal. We show how the model can be used to simulate variety of energy level schemes. Furthermore, the dressed-state analysis is employed to explain the emergence and suppression of the localization peaks, and the peak positions and widths. The range of parameters for obtaining clean sub-half-wavelength localization is identified.

Constraints on the deformation scale of a geometry in the cotangent bundle

description: There are several studies proposing phenomenological consequences of a deformation of special and general relativity. Here, we cast novel constraints on the deformation parameter of a metric in the cotangent bundle accounting for a curved momentum space. In an expanding universe, we study three possible observations that could restrict our model, focusing on the deformations of velocity, redshift and luminosity distance, which in the aforementioned framework, depend on the energy of the particles. We find that for an energy dependent velocity there would be no time delay for massless particles since also the observed distance to the source depends on the energy. For the redshift and luminosity distance we see that a scale of the order of some keV could be compatible with our model. This shows that the constraints on the high-energy scale parametrizing the momentum dependent deviation from a Friedmann-Robertson-Walker metric are at the moment weak due to the fact that the precision (rather than energies) needed in the observational constraints are extremely high. However, this is not the case when considering the synchrotron radiation. Indeed, the observation of such emission from the Crab Nebula, for deformations leading to subluminal propagation at high energies, leads to a constraint for the high-energy scale of the order of 1 PeV.

Extra centrosomes delay DNA damage-driven tumorigenesis

description: Centrosomes act as microtubule organizing centers and are critical for faithful chromosome segregation in mitosis. Deregulated centrosome numbers are frequently found in human cancer and can promote malignancies in model organisms. Current research aims to clarify if extra centrosomes are cause or consequence of malignant transformation, and if their biogenesis can be targeted for therapy. Here, we show that oncogene-driven blood cancer is inert to genetic manipulation of centrosome numbers, whereas the formation of DNA damage-induced malignancies is delayed. This unexpected phenomenon is due to extra centrosomes eliciting a pro-death signal engaging the apoptotic machinery. Apoptosis induction requires the PIDDosome multiprotein complex, as it can be abrogated by loss of any of its three components, Caspase-2, Raidd/Cradd or Pidd1. BCL2 overexpression equally blocks cell death documenting for the first time induction of mitochondrial apoptosis downstream of extra centrosomes. Our findings demonstrate context-dependent effects of centrosome amplification during transformation and ask to adjust current believe that extra centrosomes are intrinsically pro-tumorigenic.
