description: Considering the importance role of Indonesia’s Small and Medium Enterprises (SMEs) in economic development and their highly dependency on bank loan, this thesis attempts to explore whether shocks in Indonesian banking market affect small business lending during 2007–2014. This thesis examines the impacts of bank governance and competition on SME lending by using the Generalised Method of Moment (GMM) estimator and investigates the SME lending cyclicality across bank ownership by employing the Least Square Dummy Variable (LSDV) estimator. The contributions of this thesis are as follow. First, it encompasses both nationally- and locally-owned government banks, and both foreign de novo and acquired banks in the same analysis. Second, this is the first study that examines banks’ SME lending after they went public. Third, it adds to the literature by showing the impact of Indonesian banking competition on SME lending. Fourth, this is the first study that tests the effect of crisis on SME lending across five bank types.The findings provide support to the role of government banks in correcting the market failure by granting the largest amount of SME loans and more loans in difficult economic times. Meanwhile, private and regional development banks have the highest SME loan shares, highlighting the informational advantage of small-size banks. Their limited capital may nonetheless hinder them from devoting a large amount of loans and drive lending curtailment during crises. The results also confirm the foreign-bank barriers hypothesis, however, foreign acquired banks have better capacity to cater for SMEs that may be attributable to their informational and screening advantages. In addition, the findings show that governance changes of foreign acquisition and initial public offering impair SME lending while those of merger and acquisitions benefits the lending. Furthermore, the findings favour the market power hypothesis of banking concentration and indicate a U-shaped effect of bank’s market power on SME lending.

description: We present an inflationary universe model which utilizes two coupled real scalar fields. The inflation field $ϕ$ experiences a first order phase transition and its potential dominates the energy density of the Universe during the inflationary epoch. This field $ϕ$ is initially trapped in its metastable minimum and must tunnel through a potential barrier to reach the true vacuum. The second auxiliary field $ψ$ couples to the inflaton field and serves as a catalyst to provide an abrupt end to the inflationary epoch; i.e., the $ψ$ field produces a time-dependent nucleation rate for bubbles of true $ϕ$ vacuum. In this model, we find that bubbles of true vacuum can indeed percolate and we argue that thermalization of the interiors can more easily take place. The required degree of flatness (i.e., the fine tuning) in the potential of the $ψ$ field is comparable to that of other models which invoke slowly rolling fields. Pseudo Nambu-Goldstone bosons may naturally provide the flat potential for the rolling field.

description: We investigate the baryon mass spectrum in quenched lattice QCD with exact chiral symmetry. For 100 gauge configurations generated with Wilson gauge action at $ β= 6.1 $ on the $ 20^3 \times 40 $ lattice, we compute (point-to-point) quark propagators for 30 quark masses in the range $ 67 {MeV} \le m_q \le 1790 {MeV} $. For baryons only composed of strange and charm quarks, their masses are extracted directly from the time correlation functions, while for those containing $ u (d) $ light quarks, their masses are obtained by chiral extrapolation to $ m_π= 135 $ MeV. Our results of baryon masses are in good agreement with experimental values, except for the negative parity states of $ Λ$ and $ Λ_c $. Further, our results of charmed (including doubly-charmed and triply-charmed) baryons can serve as predictions of QCD.

Characterization of the role of p59Fyn in T cell development and anergy
Creators: name: Utting, Oliver B.
Publisher: name: University of British Columbia
Year: 2009

description: Signaling via the T cell receptor (TCR) is essential for the development of thymocytes and the mounting of peripheral T cell responses. Studies of proximal TCR signaling have demonstrated that two kinases, Lck and Fyn, are involved in the initial TCR phosphorylation events that eventually lead to T cell activation. Studies of these two kinases generally point to Lck having a major role in TCR signaling and to Fyn playing a secondary, perhaps redundant role. In this thesis I have investigated the hypothesis that the role Fyn plays in T cell signaling is not redundant, and that Fyn is important for both thymocyte selection and peripheral T cell responses. Using transgenic mice that express TCRs with different affinities for their ligands, I have found that Fyn plays an important role in thymocyte selection and that Fyn is required for T cell responses to low affinity ligands. T cell anergy is an important form of T cell tolerance. Fyn has often been implicated in T cell anergy, but the requirement for Fyn in this phenomenon is still unclear. I have characterized a model for in vivo induced T cell anergy that involves a mature CD4⁻CD8⁻ αβTCR⁺ population of peripheral T cells. Using this model system, I found that deletion of Fyn led to a partial recovery from the proliferation defect observed in anergic cells. These anergic cells also have an enhanced ability to survive in vitro. Enhanced survival of anergic cells was dependent on signaling through elevated expression of IL-2Rβ in a Fyn-dependent manner. It appears that Fyn plays unique roles in the induction of T cell anergy and the survival of anergic T cells. Biochemical characterization of anergic T cells revealed signaling defects associated with incomplete phosphorylation of TCR-ζ, a failure to phosphorylate ZAP-70 and LAT, and a failure to mobilize intracellular calcium. Signaling via the Ras pathway is completely intact in these cells, and they have a lowered triggering threshold for activation and hyperproliferate if exogenous IL-2 is added. These unique properties of this population of anergic T cells indicate that these cells may be re-activated by bystander immune responses.

description: The complete gauge-invariant set of the one-loop QED corrections to the parity-nonconserving (PNC) amplitude in cesium and francium is evaluated to all orders in $αZ$ using a local form of the Dirac-Fock potential. The calculations are performed in both length and velocity gauges for the absorbed photon and the total binding QED correction is found to be $-$0.27(3)% for Cs and $-$0.28(5)% for Fr. Moreover, a high-precision calculation of the electron-correlation and Breit-interaction effects on the 7$s-8s$ PNC amplitude in francium using a large-scale configuration-interaction Dirac-Fock method is performed. The obtained results are employed to improve the theoretical predictions for the PNC transition amplitude in Cs and Fr. Using an average value from two most accurate measurements of the vector transition polarizability, the weak charge of $^{133}$Cs is derived to amount to $ Q_W=-72.65(29)_{\rm exp}(36)_{\rm theor}$. This value deviates by $1.1σ$ from the prediction of the standard model. The values of the $7s$-$8s$ PNC amplitude in $^{223}$Fr and $^{210}$Fr are obtained to be $-$15.49(15) and $-$14.16(14), respectively, in units of i$\times 10^{-11}(-Q_W)/N$ a.u.

description: We develop an Evolutionary Markov Chain Monte Carlo (EMCMC) algorithm for sampling spatial partitions that lie within a large and complex spatial state space. Our algorithm combines the advantages of evolutionary algorithms (EAs) as optimization heuristics for state space traversal and the theoretical convergence properties of Markov Chain Monte Carlo algorithms for sampling from unknown distributions. Local optimality information that is identified via a directed search by our optimization heuristic is used to adaptively update a Markov chain in a promising direction within the framework of a Multiple-Try Metropolis Markov Chain model that incorporates a generalized Metropolis-Hasting ratio. We further expand the reach of our EMCMC algorithm by harnessing the computational power afforded by massively parallel architecture through the integration of a parallel EA framework that guides Markov chains running in parallel.

description: Let Gr$(k,n)$ be the Grassmannian. The quantum multiplication by the first Chern class $c_1({\rm Gr}(k,n))$ induces an endomorphism $\hat c_1$ of the finite-dimensional vector space $\mathrm{QH}^*({\rm Gr}(k,n))_{|q=1}$ specialized at $q=1$. Our main result is a case that a conjecture by Galkin holds. It states that the largest real eigenvalue of $\hat{c}_1$ is greater than or equal to $\dim {\rm Gr}(k,n)$+1 with equality if and only if Gr$(k,n)=\mathbb{P}^{n-1}$.

Two realization forms of a waveguide-to-grating shear angle are considered. The cross-polarization used as a figure-of-merit is shown to be strongly dependent on the grating perturbation strength and is a crucial limitation not only for the grating splitting performance, but also for its coupling efficiency.

description: We report the discovery of a mid-infrared (MIR) flare using WISE data in the center of the nearby Seyfert 1.9 galaxy MCG-02-04-026. The MIR flare began in the first half of 2014, peaked around the end of 2015, and faded in 2017. During these years, energy more than $7\times10^{50}$ erg was released in the infrared, and the flare's MIR color was generally turning red. We detected neither optical nor ultraviolet (UV) variation corresponding to the MIR flare based on available data. We explained the MIR flare using a dust echo model in which the radiative transfer is involved. The MIR flare can be well explained as thermal reradiation from dust heated by UV-optical photons of a primary nuclear transient event. Although the transient event was not seen directly due to dust obscuration, we can infer that it may produce a total energy of at least $\sim10^{51}$ erg, most of which was released in less than $\sim$3 years. The nature of the transient event could be a stellar tidal disruption event by the central supermassive black hole (SMBH), or a sudden enhancement of the existing accretion flow onto the SMBH, or a supernova which was particularly bright.

description: The goal of the Financial Independence policy conference held on September 16 and 17, 2024 in Washington, D.C. was to bring together experts from the asset and income fields to share theory, evidence, and best practices. The conference was divided into four sessions. The first two sessions were on Children’s Savings Accounts and Baby Bonds, the asset arm of the conference. The third session focused on the income arm. More specifically, it focused on Unconditional Cash Transfers, the Child Tax Credit, and Child Allowances. The final session focused on why solving poverty requires both asset and income proponents to come together. This policy brief is part of the Children’s Savings Accounts session.
description: Community Scholarships provide an innovative mechanism to drive additional capital into accounts. Functionally, Community Scholarships are contributions to groups of NYC Scholarship Accounts through a donation to NYC Kids RISE. NYC Kids RISE deposits 100% of the donations received for Community Scholarships into the NYC Scholarship Accounts of the designated group of students. They enable local organizations, businesses, neighbors, and other public and private systems to direct funds to students’ educational savings, leveraging local assets to build financial wealth in and with communities that have faced systemic barriers to wealth-building. In this way, CSAs provide donors with an institutional structure for making donations to children in their communities. The effect of Community Scholarships is to expand the streams of assets flowing into a child’s account beyond family savings and the initial seed deposits and rewards provided by NYC Kids RISE.

description: We study experimentally and theoretically the response of a two-component Fermi condensate in the strongly-interacting regime to a quench of the interaction strength. The quench is realized using a radio-frequency $π$-pulse to a third internal level with a different interaction strength. We find that the quench excites the monopole mode of the trap in the hydrodynamic regime and that an initial change of the condensate properties takes place on a time scale comparable or even larger than the quasi-particle relaxation time.

description: This paper includes two parts. The first is to present the spectral energy distributions (SEDs) of 49 globular cluster (GC) X-ray sources in the BATC 13 intermediate-band filters from 3800 to 10000 A, and identify 8 unidentified X-ray sources in M31. Using the X-ray data of Einstein observation from 1979 to 1980, ROSAT HRI observation in 1990, Chandra HRC and ACIS-I observations from 1999 to 2001, and the BATC optical survey from 1995 to 1999, we find 49 GC X-ray sources and 8 new unidentified X-ray sources in the BATC M31 field. By analyzing SEDs and FWHMs, 4 of the 8 X-ray sources may be GC candidates. The second is to present some statistical relationships about 62 GC X-ray sources, of which 58 are already known, and 4 are identified in this paper. The distribution of M31 GC X-ray sources' V mags is bimodal, with peaks at m_v = 15.65 and m_v = 17.89, which is different from the distribution of GC candidates. The distribution of B-V color shows that,the GC X-ray sources seem to be associated preferentially with the redder GCs, in agreement with the previous results. Kolmogorov-Smirnov test shows that the maximum value of the absolute difference of B-V distributions of GC X-ray sources and GCs is D_{max}=0.181, and the probability P=0.068 which means we can reject the hypothesis that the two distributions are the same at the 90.0% confidence level. In the end, we study the correlation between X-ray luminosity (0.3-10 keV) and the optical luminosity (in V band) of the GC X-ray sources in M31, and find that there exits a weak relationship with the linear correlation coefficient r = 0.36 at the confidence level of 98.0%.

Sources of Machine-Tool Industry Leadership in the 1990s: Overlooked Intrafirm Factors

description: Through the use of extensive field research and an original international questionnaire, the main sources of the leapfrogging development of the Japanese machine-tool industry in the past 19 years were investigated. Past studies have emphasized the strategic R&D alliance with superlative computerized numerical control (CNC) makers, the extensive use of outsourcing from excellent precision parts' suppliers, and the extraordinary development of automakers. This paper critically considered these factors and verified their inadequacy in explaining the further development of this industry in the 1990s. Hence, attention was paid to the significant roles of "intrafirm factors" such as: (a) the simultaneous and cross-functional information sharing system at an early stage of new product development processes; (b) the positive and early participation of frontline skilled workers in assembly or machining shops; and (c) the existence of highly skilled assemblymen or machinists. The significant roles of these intrafirm factors were robustly validated by the statistical analysis of the questionnaire survey as well as by the results of our field research. The results showed striking similarities between the Japanese and the German machine-tool makers and notable dissimilarities between the two and the US makers.

description: This paper sets out a framework for estimating household preferences over a broad range of housing and neighborhood characteristics, some of which are determined by the way that households sort in the housing market. This framework brings together the treatment of heterogeneity and selection that has been the focus of the traditional discrete choice literature with a clear strategy for dealing with the correlation of unobserved neighborhood quality with both school quality and neighborhood sociodemographics. We estimate the model using rich data on a large metropolitan area, drawn from a restricted version of the Census. The estimates indicate that, on average, households are willing to pay an additional one percent in house prices - substantially lower than in prior work - when the average performance of the local school is increased by 5 percent. There is also evidence of considerable preference heterogeneity. We also show that the full capitalization of school quality into housing prices is typically 70-75 percent greater than the direct effect as the result of a social multiplier, neglected in the prior literature, whereby increases in school quality also raises prices by attracting households with more education and income to the corresponding neighborhood.

description: This paper examines the relationship between the official and parallel exchange rates, in three Caribbean countries, Guyana, Jamaica and Trinidad, during the 1985-1993 period using cointegration, Granger causality, and reduced form methods. The official and parallel rates are cointegrated in all three countries, but with significant average disparity between them in Guyana and Trinidad, which unlike Jamaica applied infrequent and large adjustments to their official rates. The causation is bi-directional in the case of Jamaica and uni-directional, with changes in the official rate Granger causing changes in the parallel rate, in the cases of Guyana and Trinidad, reflecting the difference in their official exchange rate policies. Our reduced form estimates indicate that exchange controls, expansionary fiscal and monetary policy, and changes of government mostly have the expected positive effect on the black market premium. After past values of the premium, exchange controls exert the strongest impact on the premium.

description: Surfactants in aqueous solutions self-assemble in the presence of salt, to form long, flexible worm-like micelles (WLM). WLM solutions exhibit viscoelastic properties and are used in many applications, such as for cosmetic products, drag reduction and hydraulic fracturing. The dynamics of bubbles in WLM solutions are important considerations for the stability of many of these products. In this manuscript, we investigate the thin film drainage dynamics leading up to the coalescence of bubbles in WLM solutions. The salts and surfactant type and concentrations were chosen so as to have the viscoelastic properties of the tested WLM solutions span over two orders of magnitude in moduli and relaxation times. The various stages in drainage and coalescence - the formation of a thick region at the apex - a dimple, the thinning and washout of this dimple and the final stages of drainage before rupture, are modified by the viscoelasticity of the wormlike micellar solutions. As a result of the unique viscoelastic properties of the WLM solutions, we also observe a number of interesting fluid dynamic phenomena during the drainage process including elastic recoil, thin film ripping and single-step terminal drainage.

description: The aim of this work is to present an overview of the derivation of the effective shell-model Hamiltonian and decay operators within many-body perturbation theory, and to show the results of selected shell-model studies based on their utilisation. More precisely, we report some technical details that are needed by non-experts to approach the derivation of shell-model Hamiltonians and operators starting from realistic nuclear potentials, in order to provide some guidance to shell-model calculations where the single-particle energies, two-body matrix elements of the residual interaction, effective charges and decay matrix elements, are all obtained without resorting to empirical adjustments. On the above grounds, we will present results of studies of double-beta decay of heavy-mass nuclei where shell-model ingredients are derived from theory, so to assess the reliability of such a way to shell-model investigations. Attention will be also focussed on the relevant aspects that are connected to the behavior of the perturbative expansion, whose knowledge is needed to establish limits and perspectives of this approach to nuclear structure calculations.

description: Distance measurements to molecular clouds are essential and important. We present directly measured distances to 169 molecular clouds in the fourth quadrant of the Milky Way. Based on the near-infrared photometry from the Two Micron All Sky Survey and the Vista Variables in the Via Lactea Survey, we select red clump stars in the overlapping directions of the individual molecular clouds and infer the bin averaged extinction values and distances to these stars. We track the extinction versus distance profiles of the sightlines toward the clouds and fit them with Gaussian dust distribution models to find the distances to the clouds. We have obtained distances to 169 molecular clouds selected from Rice et al. The clouds range in distances between 2 and 11 kpc from the Sun. The typical internal uncertainties in the distances are less than 5 per cent and the systematic uncertainty is about 7 per cent. The catalogue presented in this work is one of the largest homogeneous catalogues of distant molecular clouds with the direct measurement of distances. Based on the catalogue, we have tested different spiral arm models from the literature.

description: This paper studies the structural impact of wage and price control policies in socialist transitional economies using a two-sector three-factor small open economy model. It illustrates the results quantitatively via simulation exercises. At the earlier stage of the transition when labor is immobile, a strict control on the price of the non-tradables and the wage rate minimizes the fall in employment and output. Also, a more severe control on the price of the non-tradables than on the wage rate alleviates the fall in the real wage at negligible costs in lost employment and output. At the later stage of the transition when labor becomes mobile, the liberalization of the price of the nontradables can proceed faster than that of the wage rate. This policy combination increases employment and output and reduces the shortage for the non-tradables, but lowers the real wage.

description: For type-1 active galactic nuclei (AGNs) for which the equatorial scattering is the dominant broad line polarization mechanism, it is possible to measure the supermassive black hole mass by tracing the Keplerian motion across the polarization plane positionangle. So far this method has been used for 30 objects but only for H$α$ emission line. We explore the possibilities this method for determining SMBH masses using polarization in broad emission lines by applying it for the first time to Mg II$λ$2798AA spectral line. We use 3D Monte Carlo radiative transfer code stokes for simultaneous modeling of equatorial scattering of H$α$, H$β$ and Mg II lines. We included vertical inflows and outflows in the MgII broad line region (BLR). We find that polarization states of H$α$ and H$β$ lines are almost identical and SMBH mass estimates differ by 7%. For Mg II line, we find that polarization angle $φ$ exhibits an additional "plateau" with a constant $φ$, which deviates than the profiles expected for pure Keplerian motion. SMBH mass estimates using Mg II line are higher by up to 35% than those obtained from H$α$ and H$β$ lines. Our model shows that for vertical inflows and outflows in the BLR that is higher or comparable to Keplerian velocity, this method can be applied as a first approximation for obtaining SMBH mass.

description: We study the interaction of fiscal and monetary policies during a currency crisis in an economy with government nominal liabilities. We show that the stock and maturity of these liabilities are key determinants of the magnitude, timing and predictability of a devaluation. Among notable features of our model, monetary authorities defend the currency parity conditional on the level of the interest rate, rather than on the stock of international reserves; budget deficits need not be high before a currency crisis; postdevaluation inflation may exhibit little persistence, and money demand need not fall after the crisis.

description: This paper studies the causes and consequences of racial segregation using a new general equilibrium model that treats neighborhood compositions as endogenous. The model is estimated using unusually detailed restricted Census microdata covering the entire San Francisco Bay Area, and in combination with a rich array of econometric estimates, serves as a powerful tool for carrying out counterfactual simulations that shed light on the causes and consequences of segregation. In terms of causes, and contrasting with prior research, our GE simulations indicate that equalizing income and education across race would be unlikely to result in significant reductions in racial segregation, as minority households would sort into newly formed minority neighborhoods. Indeed, among Asian and Hispanic households, segregation increases. In terms of consequences, this paper provides the first evidence that sorting on the basis of race gives rise to significant reductions in the consumption of local public goods by minority households and upper-income minority households in particular. These consumption effects are likely to have important intergenerational implications.

description: Scientific application codes are often long-running time- and energy-consuming parallel codes, and the tuning of these methods towards the characteristics of a specific hardware is essential for a good performance. However, since scientific software is often developed over many years, the application software usually survives several hardware generations, which might make a re-tuning of the existing codes necessary. To simplify the tuning process, it would be beneficial to have software with inherent tuning possibilities. In this article, we explore the possibilities of tuning methods for time-step-based applications. Two different time-step-based application classes are considered, which are solution methods for ordinary differential equations and particle simulation methods. The investigation comprises a broad range of tuning possibilities, starting from the choice of algorithms, the parallel programming model, static implementation variants, input characteristics as well as hardware parameters for parallel execution. An experimental investigation shows the different characteristics of the application classes on different multicore systems. The results show that a combination of offline and online tuning leads to good tuning results. However, due to the different input characteristics of the two application classes, regular versus irregular, different tuning aspects are most essential.

description: We present a theoretical formulation for the description of nuclear excitations within the framework of relativistic random-phase approximation whereby the vacuum polarization arising from nucleon-antinucleon fields is duly accounted for. The vacuum contribution to Lagrangian is explicitly described as extra new terms of interacting mesons by means of the derivative expansion of the effective action. It is shown that the self-consistent calculation yields zero eigenvalue for the spurious isoscalar-dipole state and also conserves the vector-current density.

description: This paper presents (1) a conceptual framework for structural change when farms may be multiproduct or specialized and (2) an econometrics examination of causes of structural and total factor productivity (TFP) change for U.S. agriculture. Farm size, farm specialization, and part-time farming are the structural dimension emphasized, and they become potential channels to TFP change. Using state aggregate data starting in 1950, we conclude that input prices, public and private research, public extension, and government commodity programs have directly and indirectly caused change in U.S. farm structure and TFP. Our results suggest that changes in farm size, however, have been dominated by input price changes rather than by technology or government programs.
Determinants of School Attainment of Boys and Girls in Turkey

description: This study investigates the determinants of school attainments of boys and girls in Turkey. Although high levels of enrollments have been achieved at the primary school level for both boys and girls in much of Turkey, substantial regional differences remain. In particular, in the Southeastern region, girls begin to drop out of school around the third grade. Only half of the primary school graduates register at the middle level. Thus, the purpose of this study is to examine the determinants of educational attainments at the primary, middle and high school levels. Attainments of boys and girls are examined separately so as to shed light on the causes for the significantly lower level of attainment for girls. Understanding the constraints causing the large gender gap in Turkish education and the covariates related to lower overall educational levels may be useful to policy makers and planners.

description: In this paper we study various cosmological solutions for a D3/D7 system directly from M-theory with fluxes and M2-branes. In M-theory, these solutions exist only if we incorporate higher derivative corrections from the curvatures as well as G-fluxes. We take these corrections into account and study a number of toy cosmologies, including one with a novel background for the D3/D7 system whose supergravity solution can be completely determined. This new background preserves all the good properties of the original model and opens up avenues to investigate cosmological effects from wrapped branes and brane-antibrane annihilation, to name a few. We also discuss in some detail semilocal defects with higher global symmetries, for example exceptional ones, that could occur in a slightly different regime of our D3/D7 model. We show that the D3/D7 system does have the required ingredients to realise these configurations as non-topological solitons of the theory. These constructions also allow us to give a physical meaning to the existence of certain underlying homogeneous quaternionic Kahler manifolds.

description: We compute the decay constants of the pseudoscalar mesons D and D_{s} using a linear combination of finite energy sum rules which minimize the contribution of the unknown continuum spectral function. We employ the recent three loop calculation of the pseudoscalar two-point function expanded in powers of the running charm quark mass. The theoretical uncertainties arising from the QCD asymptotic expansion are quite relevant in this case due to the relative small scale of the charm mass. We obtain the following results: f_{D}=177 \pm 21 MeV and f_{D_{s}}=205 \pm 22 MeV. These results, within the error bars, are in good agreement with estimates obtained using Borel transform QCD sum rules, but somewhat smaller than results of recent lattice computations.
