Climate science, equity, and development : the role of international institutions in capacity building for climate change
Creators: name: Ho Lem, Claudia
Publisher: name: University of British Columbia
Year: 2012

description: Climate change is a serious global problem that will have a disproportionate impact on developing countries. The ability of these countries to cope depends, at least in part, on the strength of their human capital and institutional capacity related to climate science. This thesis begins by examining the extent to which developing country scientists are participating in global climate science, and then evaluates international efforts to build the capacity of developing country scientists to address the climate change problem. A quantitative analysis of authorship data of the United Nations Intergovernmental Panel on Climate Change (IPCC) assessment reports (1990, 1995, 2001 and 2007) reveals that developing country scientists and institutions remain grossly under-represented – even after normalizing for a number of factors. The IPCC has recently acknowledged this ongoing problem, while the international community has resolved through the United Nations Framework Convention on Climate Change (UNFCCC) process to prioritize capacity building in developing countries. Extensive open source research and interviews with key informants at leading international organizations were used for qualitative purposes to identify, analyze, and evaluate such capacity building efforts. While several impressive initiatives were identified at the regional level, most capacity building activity was isolated and likely to be of limited effectiveness in advancing concerted global action to mitigate and adapt to climate change. The overall conclusion is that the existing international approach to building scientific capacity in the developing world to address climate change is inadequate. Several significant obstacles to achieving sustainable, long- term scientific capacity to address climate change in developing countries are explored, including: institutional barriers, financial issues, the “brain drain” phenomenon, data access and quality, technology and research resource limitations, complexities with downscaling/up-scaling of climate modeling, the interdisciplinary nature of climate change, navigating the science-policy interface, and issues related to operating across culture, language, and gender. Finally, this thesis concludes that the largely ad hoc approach to individual capacity building activities should give way to a more comprehensive, integrated, strategic approach to more effectively build scientific capacity in the developing world to meet the climate change challenge.

description: We apply the 't Hooft $\bar{MS}$-based scheme to study the scheme-dependence of the QCD generalization of Crewther relation for the product of the normalised non-singlet perturbative contributions to the $e^+e^-$-annihilation Adler function and to the Bjorken sum rule of the polarized lepton-nucleon deep-inelastic scattering process. We prove that after the transformations from the pure $\bar{MS}$-scheme to the 't Hooft scheme the characteristic $\bar{MS}$-scheme theoretical property of this relation, namely the factorization of the $β$-function in its conformal symmetry breaking part, disappears. Another "non-comfortable" theoretical consequence of the application of this prescription in $\mathcal{N}=1$ SUSY QED model is mentioned. It is shown, that within the 't Hooft scheme the expansions of Green functions in terms of the Lambert function is simplified in high orders of perturbation theory. This may be considered as the attractive feature of the 't Hooft scheme, which manifest itself in high-order perturbative phenomenological applications.

description: Dusty Star-Forming Galaxies (DSFGs) are amongst the most massive and active star-forming galaxies during the cosmic noon. Theoretical studies have proposed various formation mechanisms of DSFGs, including major merger-driven starbursts and secular star-forming disks. Here, we report J0107a, a bright ($\sim8$ mJy at observed-frame 888 $μ$m) DSFG at $z=2.467$ that appears to be a gas-rich massive disk and might be an extreme case of the secular disk scenario. J0107a has a stellar mass $M_\star\sim5\times10^{11}M_\odot$, molecular gas mass $M_\mathrm{mol}\sim(1\textendash6)\times10^{11}M_\odot$, and a star formation rate (SFR) of $\sim500M_\odot$ yr$^{-1}$. J0107a does not have a gas-rich companion. The rest-frame 1.28 $μ$m JWST NIRCam image of J0107a shows a grand-design spiral with a prominent stellar bar extending $\sim15$ kpc. ALMA band 7 continuum map reveals that the dust emission originates from both the central starburst and the stellar bar. 3D disk modeling of the CO(4-3) emission line indicates a dynamically cold disk with rotation-to-dispersion ratio $V_\mathrm{max}/σ\sim8$. The results suggest a bright DSFG may have a non-merger origin, and its vigorous star formation may be triggered by bar and/or rapid gas inflow.

Moduli stabilisation in early superstring cosmology

Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study moduli stabilization by thermal effects in the cosmological context. The implementation of finite temperature, which spontaneously breaks supersymmetry, induces an effective potential at one loop level. At the points where extra massless states appear in the string spectrum, the potential develops local minima whose depth depends on the temperature. Moduli attracted to these points acquire dynamical masses which decrease with cosmological evolution. This makes the coherent scalar oscillations dilute before nucleosynthesis, and the cosmological moduli problem is avoided. In particular, we study the effective potential induced by a maximally supersymmetric heterotic string gas for spacetime dimension D>=4, and a gas of type II strings compactified on Calabi-Yau three-folds (D=4). In the former case, the local minima of the potential arise at enhanced gauge symmetry points, which can stabilize all moduli but the dilaton. In the latter case, the local minima are reached at the loci where 2-cycles or 3-cycles in the Calabi-Yau space shrink to zero size, accompanied with either conifold transitions or non Abelian gauge symmetries. This stabilizes the type II moduli which characterize the deformation of these shrinking cycles. Moduli stabilization in the dual string models is also investigated by heterotic/type I S-dualities and type II/heterotic dualities.

description: Using a sample of 158 million $Υ(2S)$ events collected with the Belle detector, we search for the first time for double charmonium decays of the $P$-wave spin-triplet bottomonium states ($Υ(2S) \to γχ_{bJ}$, $χ_{bJ} \to \jpsi \jpsi$, $\jpsi \psp$, $\psp \psp$ for J=0, 1, and 2). No significant $χ_{bJ}$ signal is observed in the double charmonium mass spectra, and we obtain the following upper limits, $\BR(χ_{bJ} \to \jpsi \jpsi)<7.1\times 10^{-5}$, $2.7\times 10^{-5}$, $4.5\times 10^{-5}$, $\BR(χ_{bJ} \to \jpsi \psp)<1.2\times 10^{-4}$, $1.7\times 10^{-5}$, $4.9\times 10^{-5}$, $\BR(χ_{bJ} \to \psp \psp)<3.1\times 10^{-5}$, $6.2\times 10^{-5}$, $1.6\times 10^{-5}$ for J=0, 1, and 2, respectively, at the 90% confidence level. These limits are significantly lower than the central values (with uncertainties of 50% to 70%) predicted using the light cone formalism but are consistent with calculations using the NRQCD factorization approach.

description: In a double-well potential, a Bose-Einstein condensate exhibits Josephson oscillations or self-trapping, depending on its initial preparation and on the ratio of inter-particle interaction to inter-well tunneling. Here, we elucidate the role of the exchange symmetry for the dynamics with a mixture of two distinguishable species with identical physical properties, i.e. which are governed by an isospecific interaction and external potential. In the mean-field limit, the spatial population imbalance of the mixture can be described by the dynamics of a single species in an effective potential with modified properties or, equivalently, with an effective total particle number. The oscillation behavior can be tuned by populating the second species while maintaining the spatial population imbalance and all other parameters constant. In the corresponding many-body approach, the single-species description approximates the full counting statistics well also outside the realm of spin-coherent states. The method is extended to general Bose-Hubbard systems and to their classical mean-field limits, which suggests an effective single-species description of multicomponent Bose gases with weakly an-isospecific interactions.

description: We use sampling techniques to find robust constraints on the masses of a possible fourth sequential fermion generation from electroweak oblique variables. We find that in the case of a light (115 GeV) Higgs from a single electroweak symmetry breaking doublet, inverted mass hierarchies are possible for both quarks and leptons, but a mass splitting more than M(W) in the quark sector is unlikely. We also find constraints in the case of a heavy (600 GeV) Higgs in a single doublet model. As recent data from the Large Hadron Collider hints at the existence of a resonance at 124.5 GeV and a single Higgs doublet at that mass is inconsistent with a fourth fermion generation, we examine a type II two Higgs doublet model. In this model, there are ranges of parameter space where the Higgs sector can potentially counteract the effects of the fourth generation. Even so, we find that such scenarios produce qualitatively similar fermion mass distributions.

Inconsistence of super-luminal Cern-Opera neutrino speed with observed SN1987A burst and neutrino mixing for any imaginary neutrino mass

description: We tried to fit in any way the recent Opera-Cern claims of a neutrino super-luminal speed with observed Supernova SN1987A neutrino burst and all (or most) neutrino flavor oscillation. We considered three main frame-works: (1) A tachyon imaginary neutrino mass, whose timing is nevertheless in conflict with observed IMB-Kamiokande SN1987A burst by thousands of billion times longer. (2) An ad hoc anti-tachyon model whose timing shrinkage may accommodate SN1987A burst but greatly disagree with energy independent Cern-Opera super-luminal speed. (3) A split neutrino flavor speed (among a common real mass relativistic neutrino electron component and a super-luminal neutrino μ) in an ad hoc frozen speed scenario that is leading to the prompt neutrino de-coherence and the rapid flavor mixing (between electron and muon ones) that are in conflict with most oscillation records. Therefore we concluded that an error must be hidden in Opera-Cern time calibration (as indeed recent rumors seem to confirm). We are also reminding the relevance of the guaranteed minimal atmospheric neutrino mass whose detection may be achieved by a milliseconds graviton-neutrino split time delay among gravity burst and neutronization neutrino peak in any future SN explosion in Andromeda recordable in Megaton neutrino detector.

description: Based on realistic simulations, we propose an hybrid method to reconstruct the lensing potential power spectrum, directly on PLANCK-like CMB frequency maps. It implies using a large galactic mask and dealing with a strong inhomogeneous noise. For l < 100, we show that a full-sky inpainting method, already described in a previous work, still allows a minimal variance reconstruction, with a bias that must be accounted for by a Monte-Carlo method, but that does not couple to the deflection field. For l>100 we develop a method based on tiling the cut-sky with local 10x10 degrees overlapping tangent planes (referred to in the following as "patches"). It requires to solve various issues concerning their size/position, non-periodic boundaries and irregularly sampled data after the sphere-to-plane projection. We show how the leading noise term of the quadratic lensing estimator applied onto an apodized patch can still be taken directly from the data. To not loose spatial accuracy, we developed a tool that allows the fast determination of the complex Fourier series coefficients from a bi-dimensional irregularly sampled dataset, without performing an interpolation. We show that the multi-patch approach allows the lensing power spectrum reconstruction with a very small bias, thanks to avoiding the galactic mask and lowering the noise inhomogeneities, while still having almost a minimal variance. The data quality can be assessed at each stage and simple bi-dimensional spectra build, which allows the control of local systematic errors.

description: We report the growth of high-quality GaN epitaxial thin films on graphene-coated c-sapphire substrates using pulsed-mode metalorganic vapor-phase epitaxy, together with the fabrication of freestanding GaN films by simple mechanical exfoliation for transferable light-emitting diodes (LEDs). High-quality GaN films grown on the graphene-coated sapphire substrates were easily lifted off using thermal release tape and transferred onto foreign substrates. Furthermore, we revealed that the pulsed operation of ammonia flow during GaN growth was a critical factor for the fabrication of high-quality freestanding GaN films. These films, exhibiting excellent single crystallinity, were utilized to fabricate transferable GaN LEDs by heteroepitaxially growing InxGa1-xN/GaN multiple quantum wells and a p-GaN layer on the GaN films, showing their potential application in advanced optoelectronic devices.

description: Forward osmosis has been widely used due to its advantages such as low energy consumption and low membrane fouling. Conventional treatment of vegetable industry wastes leaving the liquor an additional puzzle. The objective of this study is to evaluate the feasibility of reducing energy consumption by using forward osmotic membrane technology to concentrate vegetable liquor. In this research, the suitable draw solutes’ condition was investigated, results showed 1 M ammonium sulphate could reach 7.21 LMH water flux and it was chosen as the draw solution for concentrating vegetable liquor, then the long-term FO performance was compared with theoretical water flux showing that the difference of water flux decrease is caused by the organic matter. Further identification of the major foulant via a control variable method using simulated vegetable liquor leads to anthocyanins as the major foulant. This novel application of the fertilizer drawn FO process provided an environmentally friendly solution to the vegetable industry, which would potentially transform an industry into a sustainable cyclic economy.

description: No abstracts are to be cited without prior reference to the author.The complex survey of Chilean jack mackerel habitat and distribution in the southeastern Pacific outside Chile’s EEZ 25–42°S/74–126°W was carried out aboard Russian RV “Atlantida” in August-November 2009. Acoustic, ichthyological, hydrological, and ornithological surveys were undertaken. The strong differences in the density of Chilean jack mackerel were revealed, the highest density corresponded to the seasonal position of the Subtropical Southeastern Pacific Front (SSPF) between 33 and 37°S. This frontal zone was affected by the surface wind direction (mainly south–southwest) and subsurface geostrophic circulation (between 0 and 250 m from 0.2–1.0 to 7.09.7 cm/s). It was revealed that both the strongest gradients of sea surface temperature in the SSPF zone and the corresponding densest Chilean jack mackerel aggregations were, in turn, clearly marked by the most abundant seabird aggregations. The densest seabird aggregations in the SSPF zone were observed between 34–36°S/85–87°W, 34–38°S/90–96°W, 34–38°S/103–106°W, 3435°S/112–114°W, and 36–38°S/114–116°W. These zones corresponded to the densest Chilean jack mackerel aggregations and sea surface temperature gradients of SSPF greater than 0.05°C per nautical mile. The information collected may serve as an additional tool for the analysis of Chilean jack mackerel spatial distribution in this region in winter–spring. Maps of the distribution of the bird species (Daption capense (occurrence 72%), Procellaria aequinoctialis (65%), Diomedea exulans (45%), Diomedea melanophis (23%), etc.) in relation to Chilean jack mackerel aggregations and oceanographic features are presented.

description: We develop a static complexity analysis for a higher-order functional language with structural list recursion. The complexity of an expression is a pair consisting of a cost and a potential. The former is defined to be the size of the expression's evaluation derivation in a standard big-step operational semantics. The latter is a measure of the "future" cost of using the value of that expression. A translation function tr maps target expressions to complexities. Our main result is the following Soundness Theorem: If t is a term in the target language, then the cost component of tr(t) is an upper bound on the cost of evaluating t. The proof of the Soundness Theorem is formalized in Coq, providing certified upper bounds on the cost of any expression in the target language.

description: Low-temperature heat sources (80–120 °C), including low-concentration solar, shallow-well geothermal, household cogeneration and industrial waste heat, are widely abundant and have the potential to be recovered as electric energy. The integration of distillation with salinity gradient power (SGP) technologies has been proposed as an alternative to traditional technologies for harnessing such low-grade heat. In this method, heat is used to distill a salt solution, thus producing a concentrated solution and pure solvent. Controlled mixing of the two solutions at different concentrations in a salinity gradient power process converts the mixing Gibbs free energy to useful work. We analyzes the energy efficiency of distillation-SGP by conducting a thermodynamic and energy assessment of the distillation stage. Counterintuitively, the highest efficiencies are achieved by utilizing the least number of distillation effects but matching the boiling point elevation of the working solution to the available temperature difference. This is due to the entropy production during heat exchange between the distillation effects, where heat flows across a temperature difference, which is the main energy loss. Solutions with greater boiling point elevation can obtain higher efficiencies, indicating the judicious selection of working solutions with suitable thermo-physical properties can substantially improve the energy efficiency of Energy conversion SGP technologies.
The Chern-Simons diffusion rate in strongly coupled N=4 SYM plasma in an external magnetic field

description: We calculate the Chern-Simons diffusion rate in a strongly coupled N=4 SUSY Yang-Mills plasma in the presence of a constant external $U(1)_R$ magnetic flux via the holographic correspondence. Due to the strong interactions between the charged fields and non-Abelian gauge fields, the external Abelian magnetic field affects the thermal Yang-Mills dynamics and increases the diffusion rate, regardless of its strength. We obtain the analytic results for the Chern-Simons diffusion rate both in the weak and strong magnetic field limits. In the latter limit, we show that the diffusion rate scales as $B\times T^2$ and this can be understood as a result of a dynamical dimensional reduction.

description: No abstracts are to be cited without prior reference to the author.European eel (Anguilla anguilla) larvae have one of the longest larval migrations of the marine realm, swimming more than 6000 km from their spawning grounds in the Sargasso Sea to European continental shelves. The duration of this migration remains debated, being thought to be between seven months and three years long. This information is crucial, however, because it determines the period over which larvae are affected by environmental conditions and hence the subsequent recruitment success. We investigated the migration pathways and duration of eel larvae using three years of high-resolution (daily, 1/12°) velocity fields available from a MercatorOcéan model configuration without data assimilation. We specifically studied the impact of spatial and temporal resolutions on our estimates by applying various filters in time (from daily to 12-day averages) and space (from 1/12° to 1° gridcell aggregation) to the nominal model outputs. Larvae were released in the eel spawning area and considered as passive tracers at three specific depths (surface, 50 m, and 200 m). We diagnosed the intensity of water transfer between appropriate control sections that encompass the eel larva distribution. Transit ages were also investigated, with a particular focus on the pathways that minimize the connection times between the western and eastern North Atlantic. The study shows that small-scale structures (eddies, filaments) contribute to the existence of faster connections although they also correspond to additional complexity in trajectories. The shortest pathways mostly follow the Gulf Stream and the North Atlantic Drift, whereas more interior connections require time transfers less compatible with biological issues.

description: Forward osmosis has been widely used due to its advantages such as low energy consumption and low membrane fouling. Conventional treatment of vegetable industry wastes leaving the liquor an additional puzzle. The objective of this study is to evaluate the feasibility of reducing energy consumption by using forward osmotic membrane technology to concentrate vegetable liquor. In this research, the suitable draw solutes’ condition was investigated, results showed 1 M ammonium sulphate could reach 7.21 LMH water flux and it was chosen as the draw solution for concentrating vegetable liquor, then the long-term FO performance was compared with theoretical water flux showing that the difference of water flux decrease is caused by the organic matter. Further identification of the major foulant via a control variable method using simulated vegetable liquor leads to anthocyanins as the major foulant. This novel application of the fertilizer drawn FO process provided an environmentally friendly solution to the vegetable industry, which would potentially transform an industry into a sustainable cyclic economy.

description: Within the nonlinear relativistic mean field model, we derive the analytical expression of the nuclear matter fourth-order symmetry energy $E_{sym,4}(ρ)$. Based on two accurately calibrated interactions FSUGold and IU-FSU, our results show that the value of $E_{sym,4}(ρ)$ at normal nuclear matter density $ρ_{0}$ is generally less than 1 MeV, confirming the empirical parabolic approximation to the equation of state for asymmetric nuclear matter at $ρ_{0}$. On the other hand, we find that the $E_{sym,4}(ρ)$ may become nonnegligible at high densities. Furthermore, the analytical form of the $E_{sym,4}(ρ)$ provides the possibility to study the higher-order effects on the isobaric incompressibility of asymmetric nuclear matter, i.e., $K_{sat}(δ)=K_{0}+K_{sat,2}δ^{2}+K_{sat,4}δ^{4}+\mathcal{O}(δ^{6})$ where $δ=(ρ_{n}-ρ_{p})/ρ$ is the isospin asymmetry, and we find that the value of $K_{sat,4}$ is generally small compared with that of the $K_{sat,2}$. In addition, we study the effects of the $E_{sym,4}(ρ)$ on the proton fraction $x_{p}$ and the core-crust transition density $ρ_{t}$ and pressure $P_{t}$ in neutron stars. Interestingly, we find that, compared with the results from the empirical parabolic approximation, including the $E_{sym,4}(ρ)$ contribution can significantly enhance the $x_{p}$ at high densities and strongly reduce the $ρ_{t}$ and $P_{t}$ in neutron stars, demonstrating that the widely used empirical parabolic approximation may cause large errors in determining the $x_{p}$ at high densities as well as the $ρ_{t}$ and $P_{t}$ in neutron stars within the nonlinear relativistic mean field model, consistent with previous nonrelativistic calculations.

description: No abstracts are to be cited without prior reference to the author.The application of an ecosystem approach to management of the sea requires both integrated and strategic frameworks such as integrated coastal-zone management (ICZM) and the use of marine spatial planning (MSP) to minimize spatial use conflicts and environmental degradation. Such an integrated management promotes sustainable development based on achieving a balance of environmental, social, and economic objectives. Here we introduce a first draft of a generic framework developed in the EU FP7 project MESMA that gives guidance on how to assess the effectiveness of an existing management within a spatially defined area. More precisely, we define spatially managed areas as geographical entities where a marine planning framework is or will be used to manage multiple human activities in space and time while maintaining ecosystem integrity. The framework comprises practical guidance on the following steps: (i) selection of operational objectives and related criteria; (ii) collation and integration of information; (iii) performance assessment; and (iv) feedback processes. In the course of the MESMA project this generic framework will be applied and tested in a number of case studies. Here we highlight the processes and practical tasks involved in each of the framework steps, reflect on the first attempts to implement this framework and identify the requirements for practical tools such as standardized methods to map human activities and assess their cumulative impacts.

description: Simulations of cluster formation have demonstrated that condensation of baryons into central galaxies during cluster formation can drive the shape of the gas distribution in galaxy clusters significantly rounder, even at radii as large as half of the virial radius. However, such simulations generally predict stellar fractions within cluster virial radii that are ~2 to 3 times larger than the stellar masses deduced from observations. In this work we compare ellipticity profiles of clusters simulated with and without baryonic cooling to the cluster ellipticity profiles derived from Chandra and ROSAT observations in an effort to constrain the fraction of gas that cools and condenses into the central galaxies within clusters. We find that the observed ellipticity profiles are fairly constant with radius, with an average ellipticity of 0.18 +/- 0.05. The observed ellipticity profiles are in good agreement with the predictions of non-radiative simulations. On the other hand, the ellipticity profiles of the clusters in simulations that include radiative cooling, star formation, and supernova feedback (but no AGN feedback) deviate significantly from the observed ellipticity profiles at all radii. The simulations with cooling overpredict (underpredict) ellipticity in the inner (outer) regions of galaxy clusters. By comparing the simulations with and without cooling, we show that the cooling of gas via cooling flows in the central regions of simulated clusters causes the gas distribution to be more oblate in the central regions, but makes the outer gas distribution more spherical. We find that late-time gas cooling and star formation are responsible for the significantly oblate gas distributions in cluster cores, but the gas shapes outside of cluster cores are set primarily by baryon dissipation at high redshift z > 2.

From affect to action : daily emotions and non-suicidal self-injury
Creators: name: Victor, Sarah
Publisher: name: University of British Columbia

description: Non-suicidal self-injury (NSSI) is the intentional, direct injury to one’s body that results in tissue damage, is not socially sanctioned, and is not suicidal in nature. Individuals who engage in NSSI experience elevated levels of emotion dysregulation (Gratz & Tull, 2010) and negative emotional experiences (Andover & Gibb, 2010; Ross & Heath, 2002); these difficulties help explain the consistent finding that individuals typically engage in NSSI as a way to regulate emotional experiences (Klonsky, 2007). Research on emotional experiences in this population has focused primarily on broad measures of positive versus negative emotion. Little research has been done on specific emotional experiences – including the particular emotions and dimensions of emotional reactivity -- that characterize the daily lives of individuals who engage in NSSI compared to those who do not. Additionally, research is lacking regarding the specific emotional states related to prospective risk of NSSI. This study investigated specific emotions and three dimensions of emotional reactivity – frequency, intensity, and duration -- in a sample of primarily university undergraduates with either no history of NSSI or a recent history of NSSI. Participants completed baseline measures of specific emotional experiences and NSSI behaviors, as well as potentially relevant confounds such as personality disorder symptoms. Participants then completed daily diary measures of specific emotional experiences and NSSI behaviors over fourteen days. Results indicated that individuals with a history of NSSI experience significantly greater levels of several negative emotional states, and significantly lower levels of several positive emotional states, than individuals with no NSSI history. The emotion that best differentiated current self-injurers was high self-dissatisfaction. Prospectively, baseline report of duration of negative emotional experiences best predicted performance of NSSI during the subsequent diary period. These results suggest that self-dissatisfaction may be a specific emotional experience associated with the decision to engage in NSSI, while the duration of negative emotional experiences may be related to continuing NSSI behaviors in individuals with a history of NSSI.
