description: El presente estudio analiza la relación entre la pobreza de los hogares y los impactos de políticas activas de promoción del empleo en el Perú. En particular, analizamos el Programa de Capacitación Laboral Juvenil PROJOVEN, que, desde 1996, ha beneficiado directamente a cerca de 50.000 jóvenes pobres. La situación de pobreza de los beneficiarios de PROJOVEN es aproximada con un índice basado en 21 activos de los hogares. Tres resultados principales emergen. Primero, las desigualdades demográficas y socioeconómicas encontradas entre los beneficiarios y la población elegible se deben principalmente a decisiones individuales de los jóvenes antes que a decisiones administrativas del operador del programa. Segundo, se observa alta heterogeneidad en la distribución de impactos por cuantiles de ingresos y fuertes diferencias en la distribución de impactos entre varones y mujeres. Tercero, la heterogeneidad de los impactos no se explica por el nivel de pobreza de los beneficiarios. Los más pobres entre los pobres se benefician igual del programa que los menos pobres. Es la entidad que proporciona los servicios de capacitación (calidad) la que explica la heterogeneidad de los impactos.

description: We studied the magnetic properties of self-assembled aggregates of BiFeO3 nanoparticles (~ 20-40 nm). The aggregates formed two different structures - one with limited and another with massive cross-linking - via `drying-mediated self-assembly' process following dispersion of the nanoparticles within different organic solvents. They exhibit large coercivity H_C (>1000 Oe) and exchange bias field H_E (~ 350-900 Oe) in comparison to what is observed in isolated nanoparticles (H_C ~ 250 Oe; H_E ~ 0). The H_E turns out to be switching from negative to positive depending on the structure of the aggregates with |H_E| being larger. The magnetic force microscopy reveals the magnetic domains (extending across 7-10 nanoparticles) as well as the domain switching characteristics and corroborate the results of magnetic measurements. Numerical simulation of the `drying-mediated-self-assembly' process shows that the nanoparticle-solvent interaction plays an important role in forming the `nanoparticle aggregate structures' observed experimentally. Numerical simulation of the magnetic hysteresis loops, on the other hand, points out the importance of spin pinning at the surface of nanoparticles as a result of surface functionalization of the particles in different suspension media. Depending on the concentration of pinned spins at the surface pointing preferably along the easy-axis direction - from greater than 50\% to less than 50% - H_E switches from negative to positive. Quite aside from bulk sample and isolated nanoparticle, nanoparticle aggregates - resulting from surface functionalization - therefore, offer remarkable tunability of properties depending on structures.

description: Chemical selectivity is a phenomenon displayed by potential energy surfaces (PES) that is relevant for many organic chemical reactions whose PES feature a valley-ridge inflection point (VRI) in the region between two sequential index-1 saddles. In this letter we describe the underlying dynamical phase space mechanism that qualitatively determines the product distributions resulting from bifurcating reaction pathways. We show that selectivity is a consequence of the heteroclinic and homoclinic connections established between the invariant manifolds of the families of unstable periodic orbits (UPOs) present in the system. The geometry of the homoclinic and heteroclininc connections is determined using the technique of Lagrangian descriptors, a trajectory-based scalar technique with the capability of unveiling the geometrical template of phase space structures that characterizes transport.

description: We consider a cosmological model with a variable gravitational constant, G, based on a scalar-tensor theory. Using the recent observational data for the Hubble diagram of type Ia supernovae (SNeIa) we find a phenomenological expression describing the variation of G. The corresponding variation of the fine structure constant αwithin multidimensional theories is also computed and is shown not to support known constraints on Δα/ α.

Female survivors of intimate partner violence: financial strain, depression, and financial education
Creators: name: Lin, Hsiu-Fen
Publisher: name: No Publisher Supplied
Year: 2021

description: This dissertation emphasizes economic consequences of intimate partner violence (IPV) and prioritizes financial education as an effective intervention to enhance mental and financial well-being of female survivors. The dissertation consists of three independent studies to investigate how financial strain interacts with different forms of abuse, depression, and financial education simultaneously. The main focus is financial strain which performs three different roles in each paper based on the Stress Process Model. Financial strain is an outcome variable of IPV in Paper 1; financial strain is a predictor leading to depression in Paper 2, and financial strain is a mediator between financial education and depression in Paper 3. The dissertation provides a comprehensive understanding of interconnections between financial strain with such variables by examining multitudinous stress models using longitudinal data from the randomized controlled trial design of an evaluation research study. The findings of the three papers give evidence to the significant effects of financial strain on female IPV survivors: Paper 1 finds that economic abuse is related to financial strain more than other forms of IPV; Paper 2 demonstrates that financial strain is the mediator between economic abuse and depression, and Paper 3 confirms that financial education decreases financial strain which, in turn, decreases depression. The implications for social work practice, policy, education, and research are discussed.

description: The study of brane intersections has provided important insights into a possible non-commutative structure of spacetime geometry. In this paper we focus on the D1$\bot$D3 system. We compare the D1 and D3 descriptions of the interesection and search for non-static solutions of the D3$\bot$D1 funnel equations in the presence of a worldvolume electric field. We find that the D1 and D3 descriptions do not agree. We find time dependent solutions that are a natural generalization of those found without the electric field.

description: The United States House of Representatives passed a climate change bill entitled “The American Clean Energy and Security Act” in June 2009. The bill establishes a combined efficiency and renewable electricity standard which requires retail electricity suppliers to utilize 20% renewable energy by 2020. The objective of this study is to estimate the costs of the American Clean Energy and Security Act in crop production and the benefits of carbon sequestration under the legislation. This study especially evaluates the impact of the legislation on the North Dakota farm income under a Cap and Trade system with and without carbon sequestration. Three different carbon sequestration programs are evaluated to estimate the impact of each program on the net farm income in North Dakota: no-till farming, wetlands restoration and wood land establishment. The North Dakota Representative Farm Model operational a North Dakota State University was used to estimate the impact of the Cap and Trade legislation and evaluate the impact of the various carbon sequestration programs.

description: Problems of pulse excitation in an acoustic waveguide with a flexible wall and in an acoustic half-space with a flexible wall are studied. In both cases the flexible wall is described by a thin plate equation. The solutions are written as double Fourier integrals. The integral for the waveguide is computed explicitly, and the integral for the half-space is estimated asymptotically. A special attention is paid to the pulse, which is a harmonic wave of a finite duration associated with the coincidence point of the dispersion diagrams of the acoustic medium and the plate. The method of estimating of the double Fourier integral is applied to the problem of excitation of waves in a system composed of an ice plate, water substrate, and the air.
Pricing in a congestible service industry with a focus on the ski industry

Publisher: name: University of British Columbia
Year: 2009

description: In 2003, the Centre for Operations Excellence at the University of British Columbia's Sauder School of Business worked on a project for a company in the resort industry. The project was an initial attempt to develop and implement a pricing management practice for the ski lift ticket business of that company. Our main deliverable was the development of an Excel-based tool with a user-friendly interface that could help the company in their budgeting of the ski lift ticket business. After completing the project, we did some further investigation relative to pricing management techniques that could be applied to this sort of business, namely a congestible service industry. In this thesis we argue that a revenue management system could bring substantial benefits if implemented in this industry. We also identify the requirements and main features of a revenue management system applied to congestible service industries. Although revenue management is a very popular system in fields such as the airline, hotel and car rental industry, none of them can be classified as congestible industries. The ski lift ticket industry and similar industries possess one characteristic that differentiates them from the ones previously mentioned, there is no fixed capacity. This is the reason why we considered important to study the application of revenue management in congestible service industries.

description: Context: Hot coronal jets are a basic observed feature of the solar atmosphere whose physical origin is still being actively debated. Aims: We study six recurrent jets occurring in the active region NOAA 12644 on April 04, 2017. They are observed in all the hot filters of AIA as well as cool surges in IRIS slit-jaw high spatial and temporal resolution images. Methods: The AIA filters allow us to study the temperature and the emission measure of the jets using the filter ratio method. We study the pre-jet phases by analyzing the intensity oscillations at the base of the jets with the wavelet technique. Results: A fine co-alignment of the AIA and IRIS data shows that the jets are initiated at the top of a canopy-like, double-chambered structure with cool emission on one side and hot emission in the other. The hot jets are collimated in the hot temperature filters, have high velocities (around 250 km/s) and accompanied by the cool surges and ejected kernels both moving at about 45 km/s. In the pre-phase of the jets, at their base we find quasi-periodic intensity oscillations in phase with small ejections; they have a period between 2 and 6 minutes and are reminiscent of acoustic or MHD waves. Conclusions: This series of jets and surges provides a good case-study to test the 2D and 3D magnetohydrodynamic (MHD) models that result from magnetic flux emergence. The double-chambered structure found in the observations corresponds to the cold and hot loop regions found in the models beneath the current sheet that contains the reconnection site. The cool surge with kernels is comparable with the cool ejection and plasmoids that naturally appear in the models.

Frequency-dependent software reverberation : design and implementation of a seven octave-band reverberator
Creators: name: Halingten, Kurtis
Publisher: name: University of British Columbia
Year: 2009

description: Software reverberators are used to superimpose reverberation on audio signals, and are used extensively in the multimedia and broadcasting industries. Several commercially-available reverberators claim to support frequency-dependent reverberation, but none have been found to implement octave-band frequency-dependent reverberation. The objective of the research reported here was to develop a reverberator capable of accurately adding reverberation to digital audio signals, with desired reverberation times from 0 to 2 seconds specified for individual octave frequency bands from 125 Hz to 8000 Hz. The physics governing diffuse reverberation have been reviewed. An indepth investigation of the methods to measure reverberation was performed. Measurement of frequency-dependent reverberation times reported in this thesis used an iterative noise-reduction algorithm combined with a novel, unique, rationalized reverberation time measurement algorithm. The properties of the common DSP filters used for superimposing reverberation have been reviewed. Several published reverberator designs have been simulated, but were found to be unsuitable to meet the research objectives. This fact, combined with the limited reverberation functionality of current audio processing software development kits, prompted the development of new reverberators. Several new software reverberators are presented. Two of these are based on a computationally efficient multirate design. A l l of the prototypes satisfied the research objective of accurate superposition of octave-band reverberation. The best design was implemented in a Microsoft Windows DLL.

description: The divergence structure of supergravity has long been a topic of concern because of the theory's non-renormalizability. In the context of string theory, where perturbative finiteness should be achieved, the supergravity counterterm structures remain nonetheless of importance because they still occur, albeit with finite coefficients. The leading nonvanishing supergravity counterterms have a particularly rich structure that has a bearing on the preservation of supersymmetry in string vacua in the presence of perturbative string corrections. Although the holonomy of such manifolds is deformed by the corrections, a Killing spinor structure nevertheless can persist. The integrability conditions for the existence of such Killing spinors remarkably remain consistent with the perturbed effective field equations.

description: Molecular hydrogen ions are of metrological relevance due to the possibility of precise theoretical evaluation of their spectrum and of external-field-induced shifts. In homonuclear molecular ions the electric dipole $E1$ transitions are strongly suppressed, and of primary laser spectroscopy interest is the electric quadrupole ($E2$) transition spectrum. In continuation of previous work on the H$_2^+$ ion, we report here the results of the calculations of the hyperfine structure of the laser-induced electric quadrupole transitions between a large set of ro-vibrational states of D$_2^+$; the inaccuracies of previous evaluations have been corrected. The effects of the laser polarization are studied in detail. We show that the electric quadrupole moment of the deuteron can in principle be determined with low fractional uncertainty $(\simeq1\times10^{-4})$ by comparing the results presented here with future data from precision spectroscopy of D$_2^+$.
description: 19 pages, 4 figures. Comparison with the available experimental data about the hyperfine structure of D2+ has been added in Section IIC; A new Section IIID has been added with a thorough analysis of the determination of the electric quadrupole moment of the deuteron from D2+ spectroscopy; A new Section IIIE has been added discussing further applications of the composite frequency method

description: Selection of beef cattle for increased net feed efficiency is a current major focus for research. At present the trait seems to be more apparent in Australia’s southern beef production system which is dominated by mixed farming enterprises. Farm-level evaluation of net feed efficiency should take account of the farming system for which it is proposed along with the dynamic nature of genetic selection. Gross margin, linear programming and multi-period linear programming approaches to evaluation of the trait at the farm-level using a representative farm are compared. Implications of the trait for researchers and beef producers are identified
Parametric Level Correlations in Random-Matrix Models

description: We show that parametric level correlations in random-matrix theories are closely related to a breaking of the symmetry between the advanced and the retarded Green's functions. The form of the parametric level correlation function is the same as for the disordered case considered earlier by Simons and Altshuler and is given by the graded trace of the commutator of the saddle--point solution with the particular matrix that describes the symmetry breaking in the actual case of interest. The strength factor differs from the case of disorder. It is determined solely by the Goldstone mode. It is essentially given by the number of levels that are strongly mixed as the external parameter changes. The factor can easily be estimated in applications.

description: This study examined the potential economic impacts in the United States of the commercial adoption of a corn rootworm (CRW) resistant transgenic corn. Using a counterfactual approach, we estimated that if the technology had been made available in the year 2000 at a price that would equate per acre costs to those for insecticide-based corn rootworm control, and adopted on all of the acres treated for corn rootworm in that year, the total benefits would have been $460 million. This benefit includes $171 million to the technology developer and seed companies, $231 million to farmers from yield gains, and a further $58 million to farmers from reduced risk, time savings, and other nonpecuniary benefits associated with reduced use of insecticides. This is a one-year benefit with 100 percent adoption. Our nation-wide survey of corn producers suggests that initial adoption might be as low as 30 percent, which means that the first-year benefits might be only one-third of the value implied by 100 percent adoption. Different pricing assumptions would mostly change the distribution of the benefits between farmers and others, so long as the pricing did not influence the adoption rate as well. Benefits over time would reflect changing adoption patterns and evolving insect resistance. Further analysis could include the effects of any refuge requirements implemented to slow the development of resistance, when such requirements are known.

description: Beef production in Bali is dominated by smallholders, just like the majority of Indonesian agriculture. A wide range of policies has been implemented to enhance development of the Bali beef industry. Knowledge about the distribution of the returns from the development of the cattle industry, including marketing, informs decision making. This paper examines the benefits from cattle development in a multi-stage production representation of the Bali beef industry using equilibrium displacement modelling (EDM). Benefits are measured as changes in economic surplus. The distribution of benefits among farmers, processors and retailers is also examined.

description: Giant molecular clouds (GMCs) and their stellar offspring are the building blocks of galaxies. The physical characteristics of GMCs and their evolution are tightly connected to galaxy evolution. The macroscopic properties of the interstellar medium propagate into the properties of GMCs condensing out of it, with correlations between e.g. the galactic and GMC scale gas pressures, surface densities and volume densities. That way, the galactic environment sets the initial conditions for star formation within GMCs. After the onset of massive star formation, stellar feedback from e.g. photoionisation, stellar winds, and supernovae eventually contributes to dispersing the parent cloud, depositing energy, momentum and metals into the surrounding medium, thereby changing the properties of galaxies. This cycling of matter between gas and stars, governed by star formation and feedback, is therefore a major driver of galaxy evolution. Much of the recent debate has focused on the durations of the various evolutionary phases that constitute this cycle in galaxies, and what these can teach us about the physical mechanisms driving the cycle. We review results from observational, theoretical, and numerical work to build a dynamical picture of the evolutionary lifecycle of GMC evolution, star formation, and feedback in galaxies.

description: A relationship between COVID-19 infection and an increasing incidence of atrial fibrillation has been observed. However, the underlying pathophysiology as a precipitant to AF has not been reviewed. This paper will consider the possible pathological and immunological AF mechanisms as a result, of COVID-19 infection. We discuss the role myocardial microvascular pericytes expressing the ACE-2 receptor and their potential for an organ-specific cardiac involvement with COVID-19. Dysfunctional microvascular support by pericytes or endothelial cells may increase the propensity for AF via increased myocardial inflammation, fibrosis, increased tissue edema, and interstitial hydrostatic pressure. All of these factors can lead to electrical perturbances at the tissue and cellular level. We also consider the contribution of Angiotensin, pulmonary hypertension, and regulatory T cells as additional contributors to AF during COVID-19 infection. Finally, reference is given to two common drugs, corticosteroids and metformin, in COVID-19 and how they might influence AF incidence.

description: Apparent critical phenomena, typically indicated by growing correlation lengths and dynamical slowing-down, are ubiquitous in non-equilibrium systems such as supercooled liquids, amorphous solids, active matter and spin glasses. It is often challenging to determine if such observations are related to a true second-order phase transition as in the equilibrium case, or simply a crossover, and even more so to measure the associated critical exponents. Here, we show that the simulation results of a hard-sphere glass in three dimensions, are consistent with the recent theoretical prediction of a Gardner transition, a continuous non-equilibrium phase transition. Using a hybrid molecular simulation-machine learning approach, we obtain scaling laws for both finite-size and aging effects, and determine the critical exponents that traditional methods fail to estimate. Our study provides a novel approach that is useful to understand the nature of glass transitions, and can be generalized to analyze other non-equilibrium phase transitions.

Preliminary results show that more than 50% of consumers would buy non-GM canola oil, even if it costs one dollar more than the GM canola oil. It was suggested that the Australian Commonwealth and State Governments should establish adequate labelling of GM products, in order to increase consumers’ awareness. Further socio-economic research is required on GM crops.

description: Future prosperity of farming businesses depends not only on immediate prospects, but also on the capability to adapt to changing circumstances. In looking to the future, farm managers need to assess where the current farming system is taking them, and whether changing to an alternative farming system might be more profitable. There are various techniques for assessing the profitability of alternative farming systems, but frequently the cost of transition is overlooked. The financial consequences of transition to a new farming system are assessed for two case study farms using a spreadsheet tool (STEP), developed by the authors. The tool assists farm managers in assessing the risk of transition strategies as well as comparing rotations.
The outer disks of galaxies: "To be or not to be truncated?"

description: We have in recent years come to view the outer parts of galaxies as having vital clues about their formation and evolution. Here, we would like to briefly present our results from a complete sample of nearby, late-type, spiral galaxies, using data from the SDSS survey, especially focused on the stellar light distribution in the outer disk. Our study shows that only the minority of late-type galaxies show a classical, exponential Freeman Type I profile down to the noise limit, whereas the majority exhibit either downbending (stellar truncation as introduced 1979 by Piet van der Kruit) or upbending profiles.

description: Non-BPS D-branes are difficult to describe covariantly in a manifestly supersymmetric formalism. For definiteness we concentrate on type IIB string theory in flat background in light-cone Green-Schwarz formalism. We study both the boundary state and the boundary conformal field theory descriptions of these D-branes with manifest SO(8) covariance and go through various consistency checks. We analyze Sen's original construction of non-BPS D-branes given in terms of an orbifold boundary conformal field theory. We also directly study the relevant world-sheet theory by deriving the open string boundary condition from the covariant boundary state. Both these methods give the same open string spectrum which is consistent with the boundary state, as required by the world-sheet duality. The boundary condition found in the second method is given in terms of bi-local fields that are quadratic in Green-Schwarz fermions. We design a special ``doubling trick'' suitable to handle such boundary conditions and prescribe rules for computing all possible correlation functions without boundary insertions. This prescription has been tested by computing disk one-point functions of several classes of closed string states and comparing the results with the boundary state computation.

PCA biplots over z-score transformed data from protein (A) and metabolite (B) showing divergence between samples from different harvesting times and the correlation of each individual variables to each displayed component. Protein PCA (A) principal component 1 (PC1) potentially gathers variability related to the photoacclimation to UV-B/C with photosynthesis PHOTOSYSTEM II D2 PROTEIN (psbD) and CHLOROPHYLL A-B BINDING PROTEIN (LHCB4) as some of its highest rank elements. Principal component 2 (PC2) collects early response elements with signaling. WD40 REPEAT PROTEIN (Cre12.g495650.t1.2), carbon metabolism a redox-related NADP MALIC ENZYME 5 (MME5) and TYPE II NADH DEHYDROGENASE (NDA5) and protein damage-associated HEAT SHOCK PROTEIN 70C, E (HSP70C, HSP70E) had the highest loadings within this component. At metabolome level (B), PC1 explain early response with phenolic metabolism protocatechuic and 4-hydroxybenzoic acids; while PC2 joins late accumulated sugars and UV shielding catechin, both related to acclimation.

Requirements for DNA-bridging proteins to act as topological barriers of the bacterial genome

description: Bacterial genomes have been shown to be partitioned into several kilobases long chromosomal domains that are topologically independent from each other, meaning that change of DNA superhelicity in one domain does not propagate to neighbors. Both in vivo and in vitro experiments have been performed to question the nature of the topological barriers at play, leading to several predictions on possible molecular actors. Here, we address the question of topological barriers using polymer models of supercoiled DNA chains. More specifically, we determine under which conditions DNA-bridging proteins may act as topological barriers. To this end, we developed a coarse-grained bead-and-spring model and investigated its properties through Brownian dynamics simulations. As a result, we find that DNA-bridging proteins must exert rather strong constraints on their binding sites: they must block the diffusion of the excess of twist through the two binding sites on the DNA molecule and, simultaneously, prevent the rotation of one DNA segment relative to the other one. Importantly, not all DNA-bridging proteins satisfy this second condition. For example, single bridges formed by proteins that bind DNA non-specifically, like H-NS dimers, are expected to fail with this respect. Our findings might also explain, in the case of specific DNA-bridging proteins like LacI, why multiple bridges are required to create stable independent topological domains. Strikingly, when the relative rotation of the DNA segments is not prevented, relaxation results in complex intrication of the two domains. Moreover, while the value of the torsional stress in each domain may vary, their differential is preserved. Our work also predicts that nucleoid associated proteins known to wrap DNA must form higher protein-DNA complexes to efficiently work as topological barriers.

description: Given the increasing concentration in numerous markets recent interest in market structure and performance has grown dramatically. The empirical research revolves around theories of industrial organization and non-cooperative game theory. Research in this area uses participant strategic action not only to define market structure but also participant conduct. In the Australian egg market and Canadian fresh chicken market we reject the more competitive assumption of Bertrand-Nash behavior in favor of Stackelberg/leader-follower relationships. In Australia Pace Farms emerges as the industry leader while in Canada generic product overwhelmingly controls the market.

Classical diffusion in double-delta-kicked particles

description: We investigate the classical chaotic diffusion of atoms subjected to {\em pairs} of closely spaced pulses (`kicks) from standing waves of light (the $2δ$-KP). Recent experimental studies with cold atoms implied an underlying classical diffusion of type very different from the well-known paradigm of Hamiltonian chaos, the Standard Map. The kicks in each pair are separated by a small time interval $ε\ll 1$, which together with the kick strength $K$, characterizes the transport. Phase space for the $2δ$-KP is partitioned into momentum `cells' partially separated by momentum-trapping regions where diffusion is slow. We present here an analytical derivation of the classical diffusion for a $2δ$-KP including all important correlations which were used to analyze the experimental data. We find a new asymptotic ($t \to \infty$) regime of `hindered' diffusion: while for the Standard Map the diffusion rate, for $K \gg 1$, $D \sim K^2/2[1- J_2(K)..]$ oscillates about the uncorrelated, rate $D_0 =K^2/2$, we find analytically, that the $2δ$-KP can equal, but never diffuses faster than, a random walk rate. We argue this is due to the destruction of the important classical `accelerator modes' of the Standard Map. We analyze the experimental regime $0.1\lesssim Kε\lesssim 1$, where quantum localisation lengths $L \sim \hbar^{-0.75}$ are affected by fractal cell boundaries. We find an approximate asymptotic diffusion rate $D\propto K^3ε$, in correspondence to a $D\propto K^3$ regime in the Standard Map associated with 'golden-ratio' cantori.
