Productivity Analysis

description: Increasing livestock product consumption in many Asian countries has been accompanied by growth in some countries’ imports of feedgrains for their domestic livestock sectors. This contributes to debate over future levels of grain imports. Yet projections often pay little attention to developments in livestock production. The impacts of technological catch‐up in livestock production on trade in livestock and grains products among countries in the Asia‐Pacific region are assessed. Tests are conducted of the hypothesis that productivity levels in the Asia‐Pacific region are converging. Projections of livestock productivity are made and incorporated in a modified GTAP model. The consequences for regional and global trade in livestock and grains products are explored.

description: Intermediate-mass black holes (IMBHs) could form via runaway merging of massive stars in a young massive star cluster (YMC). We combine a suite of numerical simulations of YMC formation with a semi-analytic model for dynamical friction and merging of massive stars and evolution of a central quasi-star, to predict how final quasi-star and relic IMBH masses scale with cluster properties (and compare with observations). The simulations argue that inner YMC density profiles at formation are steep (approaching isothermal), producing some efficient merging even in clusters with relatively low effective densities, unlike models which assume flat central profiles resembling those of globular clusters (GCs) {\em after} central relaxation. Our results can be approximated by simple analytic scalings, with $M_{\rm IMBH} \propto v_{\rm cl}^{3/2}$ where $v_{\rm cl}^{2} = G\,M_{\rm cl}/r_{\rm h}$ is the circular velocity in terms of initial cluster mass $M_{\rm cl}$ and half-mass radius $r_{\rm h}$. While this suggests IMBH formation is {\em possible} even in typical clusters, we show that predicted IMBH masses for these systems are small, $\sim 100-1000\,M_{\odot}$ or $\sim 0.0003\,M_{\rm cl}$, below even the most conservative observational upper limits in all known cases. The IMBH mass could reach $\gtrsim 10^{4}\,M_{\odot}$ in the centers nuclear star clusters, ultra-compact dwarfs, or compact ellipticals, but in all these cases the prediction remains far below the present observed supermassive BH masses in these systems.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We discuss constraints on black hole spin and spin-related astrophysics as derived from X-ray spectroscopy. After a brief discussion about the robustness with which X-ray spectroscopy can be used to probe strong gravity, we summarize how these techniques can constrain black hole spin. In particular, we highlight XMM-Newton studies of the Seyfert galaxy MCG-6-30-15 and the stellar-mass black hole GX339-4. The broad X-ray iron line profile, together with reasonable and general astrophysical assumptions, allow a non-rotating black hole to be rejected in both of these sources. If we make the stronger assertion of no emission from within the innermost stable circular orbit, the MCG-6-30-15 data constrain the dimensionless spin parameter to be a>0.93. Furthermore, these XMM-Newton data are already providing evidence for exotic spin-related astrophysics in the central regions of this object. We conclude with a discussion of the impact that Constellation-X will have on the study of strong gravity and black hole spin.

description: Spontaneous decay of an excited atom in a waveguide is essentially modified by the spatial structure of vacuum reservoir. This is particularly exciting in view of a range of applications for quantum information science. We found out that spontaneous decay can be incomplete, so the time dependence of the excited state population asymptotically approaches to a nonzero value, under the conditions when the atomic transition frequency is larger than the cutoff frequency of a waveguide and far from the vicinities of the cut-offs. Discovered effect is explained by the emergence of the dark state, which is non-decaying due to polarization selection rules. It was revealed for single-mode waveguide with rectangular cross section both in single-atom case and diatomic case when the long-range dipole-dipole interaction plays a significant role.

description: BENTHESICYMUS SPENCE BATE, 1881
Emended diagnosis: Integument membraneous; rostrum overreaching distal corneal margin; carapace with developed branchiostegal spine set on anterior margin; pleon with fourth to sixth somitess dorsally carinate, fourth somite posteriorly crenate, sixth somite posterodorsally straight; telson with posterior, triangular end-piece between apical spines, with two to three pairs of moveable dorsolateral spines and a single pair of apical spines. First maxilliped with exopod distally abruptly narrowing to a segmented distal part; second maxilliped greatly expanded, less than three times as long as broad; third maxilliped with subtriangular dactylus bearing a single strong spine at tip. First pereopod with a distal tooth on basis and ischium; fourth and fifth pereopods with dactyl slender, entire. Thelycum with a strong sharp medial ventrally directed tooth on S6 or S8, S7 with a sharp protuberance projecting anteriorly far beyond this segment. Petasma with a fan-like serrate appendix on PI and PM greatly modified, PE not distally produced.
Species included: Benthesicymus crenatus Spence Bate, 1881, Be. laciniatus Rathbun, 1906.
Type species: Benthesicymus crenatus (subsequently designated by Spence Bate, 1888).
Remarks: Two species of this genus were described, but most of the distinguishing characters (see undated summary in: Yang & Chan, 2019) may be linked to observed specimens being of a different age. Indeed, individuals of Be. crenatus are generally larger, have the hepatic spine and more teeth on the rostrum and on the crenation of the fourth pleura. These characters included in the key below should, therefore, be considered cautiously. The only reliable character is the morphology of the thelycum in adults: the large tooth is present on S 6 in B. laciniatus or on S 8 in Be. crenatus. Regrettably, in most reports, the thelycum is not illustrated with necessary accuracy and in detail (e.g. Yang & Chan, 2019).

description: In this article we analyse trends in the economic performance of the dairy processing industry and evaluate the link between these trends and the deregulation of the industry. Using Stochastic Frontier Analysis to derive Malmquist total factor productivity estimates, we show that the industry exhibits a relatively high level of technical efficiency. Victoria, the major producing state, has been effectively on the frontier over the period studied. In recent years, the rapid expansion in capital investment that has attended the shift towards deregulation, has been accompanied by an apparent slowdown in both productivity growth and technical progress. There is also evidence of a convergence in productivity levels across states.

description: Il Laboratorio di diritto amministrativo nasce come iniziativa di incontro e scambio tra giovani studiosi della materia per discutere delle ricerche in corso di svolgimento. L’idea, ispirata dall’esperienza di quanto avviene in altre realtà, soprattutto al di fuori del nostro Paese, si fonda sulla necessità di collocare, nell’ambito di un percorso di ricerca sovente caratterizzato dalla ‘solitudine’ di chi lo intraprende, un momento di confronto dialettico all’interno della comunità scientifica; un momento in cui, cioè, la comunità stessa metta a disposizione del singolo le proprie eterogenee esperienze e conoscenze, di modo che questi possa conseguire un più proficuo sviluppo del suo lavoro, nell’ottica di un complessivo arricchimento reciproco. Dopo la pubblicazione di analogo lavoro per l’anno 2019 (introdotto dalla prof.ssa Maria Alessandra Sandulli), gli esiti delle ricerche, per gli anni 2020-2021, sono oggetto di pubblicazione del presente volume, insieme agli ulteriori contributi ad essi correlati e ispirati dall’attività del Laboratorio.

description: The instability of prices and the hypothesis that speculative behaviour was one of its sources has brought renewed interest in the futures markets. In this paper, we concentrate on the European wheat futures markets (feed and milling) and the CBOT’s wheat contract as a comparison. The purpose of the paper is to study whether those markets still allow substitution price risk for basis risk. This implicitly is a test of whether the increasing presence of speculation in futures market have made them divorced from the physical markets, and therefore, not useful for commercial entities. We study two aspects: efficiency and hedging effectiveness and our results indicate that there are still a good connection between physical and futures markets, and therefore, hedging can still play an important role protecting commodity handlers against price volatility.

description: A technique for timescale analysis of spectral lags performed directly in the time domain is developed. Simulation studies are made to compare the time domain technique with the Fourier frequency analysis for spectral time lags. The time domain technique is applied to studying rapid variabilities of X-ray binaries and $γ$-ray bursts. The results indicate that in comparison with the Fourier analysis the timescale analysis technique is more powerful for the study of spectral lags in rapid variabilities on short time scales and short duration flaring phenomena.

description: In a supercritical branching particle system, the trimmed tree consists of those particles which have descendants at all times. We develop this concept in the superprocess setting. For a class of continuous superprocesses with Feller underlying motion on compact spaces, we identify the trimmed tree, which turns out to be a binary splitting particle system with a new underlying motion that is a compensated h-transform of the old one. We show how trimmed trees may be estimated from above by embedded binary branching particle systems.

description: This investigation describe the socio-productive an economical behaviour of the borrowers of the Instituto de Desarrollo Agropecuario (INDAP) of the Province of Valdivia, de Los Ríos region, and it consider the INDAP financial risk classification. The relevance of the results of this study is that the knowledge of the relationship(s) among the variables associated to the farmer and credit categories will allow to create an individual profile. To create the borrowers profile, qualitative and quantitative information was collected through a survey applied to a representative sample of 83 producers belonging to different risk categories and distributed in three communities, Valdivia, Máfil and Corral. To characterize the sample, different statistical procedures were used, such as: descriptive statistics, Chi-Squared test, multivariable analysis using the methods of factorial analysis with the principal components and analysis of clusters, and a multiple lineal regression. The main results show that the different risk categories do not have any relationship with the studied variables. Due to the previous result, a general description of the borrowers was developed, which include the main variables that characterize the farmers of the financial system of INDAP, through the determination of four main components and four conglomerated or clusters. Finally, a model with two variables was estimated to explain the net income with respect to economic profitability and family income.

description: The prevalent modus operandi within the framework of quantum resource theories has been to characterise and harness the resources within single objects, in what we can call \emph{single-object} quantum resource theories. One can wonder however, whether the resources contained within multiple different types of objects, now in a \emph{multi-object} quantum resource theory, can simultaneously be exploited for the benefit of an operational task. In this work, we introduce examples of such multi-object operational tasks in the form of subchannel discrimination and subchannel exclusion games, in which the player harnesses the resources contained within a state-measurement pair. We prove that for any state-measurement pair in which either of them is resourceful, there exist discrimination and exclusion games for which such a pair outperforms any possible free state-measurement pair. These results hold for arbitrary convex resources of states, and arbitrary convex resources of measurements for which classical post-processing is a free operation. Furthermore, we prove that the advantage in these multi-object operational tasks is determined, in a multiplicative manner, by the resource quantifiers of: \emph{generalised robustness of resource} of both state and measurement for discrimination games and \emph{weight of resource} of both state and measurement for exclusion games.

description: We present a detailed study of the evolution of massive stars of masses 15, 20, 25 and 30 $\msun$ assuming solar-like initial chemical composition. The stellar sequences were evolved through the advanced burning phases up to the end of core oxygen burning. We present a careful analysis of the physical characteristics of the stellar models. In particular, we investigate the effect of the still unsettled reaction $^{12}$C($α$,$γ$)$^{16}$O on the advanced evolution by using recent compilations of this rate. We find that this rate has a significant impact on the evolution not only during the core helium burning phase, but also during the late burning phases, especially the shell carbon-burning. We have also considered the effect of different treatment of convective instability based on the Ledoux criterion in regions of varying molecular weight gradient during the hydrogen and helium burning phases. We compare our results with other investigations whenever available. Finally, our present study constitutes the basis of analyzing the nucleosynthesis processes in massive stars. In particular we will present a detail analysis of the {\it s}-process in a forthcoming paper.

description: Brewery industry in Chile has increased in the last period of time, as is evidenced by different factors, such as the total number of sales, number of imports and per capita beer consumption. Other sources indicate that the average price of beer has also risen, and this factor is one of the most influential in the customer’s decision of what to buy (Maturana, 2002). In Chile no research exists explaining the elements that affect the price of beer in the market, except for a presentation carried out by Contreras, Jara, Rivas and Rodríguez (2009). This research’s objective is to determine which attributes explain the price of beer in Chile. In order to achieve this objective, a list of prices of beer was used, as well as 227 beer samples taken from “The Beer Guide in Chile 2010”, Ibañez (2010). The results of the hedonic price estimation show that the variable that contributes the most in the explanation of the price of beer is “Easter Island”, followed by handmade beers. The score given by beer tasters from the guide was meaningful in the final regression model, however this variable stops being meaningful at the time of correcting for heteroscedasticity
RS1 structure-function relationships : roles in retinal adhesion and X-linked retinoschisis
Creators: name: Wu, Winco Wing-Ho
Publisher: name: University of British Columbia
Year: 2009

description: X-linked retinoschisis is a form of macular degeneration that can result in visual loss in young males or in females with both copies of the gene defective. The RS1 gene associated with X-linked retinoschisis was positionally cloned in 1997. The gene was found to encode RS1, a 224-amino acid protein containing a discoidin domain that spans most of the protein. Discoidin domains are found in a wide variety of proteins that are involved mainly in cell adhesion. This thesis investigation examined the structure-function relationships in RS1 and their roles in maintaining retinal cell adhesion and in causing X-linked retinoschisis. Results showed that RS1 exists as a single disulfide-linked homo-octamer formed by intermolecular disulfide bonds between C59 and C223. C40-C40 intermolecular disulfide bonds further result in disulfide-linked dimer formation within this octameric complex. Within the discoidin domain, C63-C219 and C110-C142 form intramolecular disulfide bonds to allow for proper protein folding and stability of the discoidin domain, and C83 exists as a free cysteine. To allow for RS1 secretion into the extracellular matrix, each RS1 subunit is cleaved after S23 by signal peptidase. The main molecular mechanisms that cause X-linked retinoschisis can be grouped into four categories: mutations in the leader sequence prevent proper RS1 targeting to the endoplasmic reticulum; most mutations in the discoidin domain prevent proper protein folding and secretion; mutations in C59 or C223 prevent octameric assembly; and R141H within the discoidin domain causes abnormal oligomer formation. A suspected polymorphism D158N was shown to behave similarly to wildtype RS1. To identify the component that RS1 interacts with, known ligands of discoidin family proteins were tested for their ability to bind RS1. Unlike Factor V, RS1 did not bind phospholipids; however, similar to discoidin I, RS1 bound to D-galactose. This interaction depended on the octameric form of RS1, as dimers or monomers interacted weakly with galactose. Isopropyl β-D-1-thiogalactopyranoside eluted RS1 from a galactose-agarose column. This property was used to purify RS1 from retinal membranes. In summary, RS1 is a lectin whose function critically depends on the proper folding of its discoidin domain and disulfide-linked octamerization.

description: The lines of HOC$^+$, HCO and CO$^+$ are considered good tracers of photon-dominated regions (PDRs) and X-ray dominated regions. We study these tracers towards regions of the Sgr B2 cloud selected to be affected by different heating mechanisms. We find the lowest values of the column density ratios of HCO$^+$ versus HOC$^+$, HCO and CO$^+$ in dense HII gas, where UV photons dominate the heating and chemistry of gas. HOC$^+$, HCO and CO$^+$ abundances and the above ratios are compared with those of chemical modeling, finding that high temperature chemistry, a cosmic-ray ionization rate of 10$^{-16}$ s$^{-1}$ and timescales $>$10$^{5.0}$ years explain well the HOC$^+$ abundances in quiescent Sgr B2 regions, while shocks are also needed to explain the highest HCO abundances derived for these regions. CO$^+$ is mainly formed in PDRs since the highest CO$^+$ abundances of $\sim$(6-10)$\times$10$^{-10}$ are found in HII regions with electron densities $>$540 cm$^{-3}$ and that CO$^+$ emission is undetected in quiescent gas. Between the ratios, the HCO$^+$/HCO ratio is sensitive to the electron density as it shows different values in dense and diffuse HII regions. We compare SiO J=2-1 emission maps of Sgr B2 with X-ray maps from 2004 and 2012. One known spot shown on the 2012 X-ray map is likely associated with molecular gas at velocities of 15-25 km s$^{-1}$. We also derive the X-ray ionization rate of $\sim$10$^{-19}$ s$^{-1}$ for Sgr B2 regions pervaded by X-rays in 2004, which is quite low to affect the chemistry of the molecular gas.

description: Excerpts from the report: One of the principal problems in marketing grain is an inadequate supply of rail equipment for moving the grain, particularly during the harvest season. In recent years, serviceable boxcars have been in short supply for prolonged periods. Shortages have been serious in the class of equipment required for transporting grain. Some cooperatives have bought or leased covered hopper cars in an attempt to solve their marketing problems caused by the shortage of cars provided by the carriers. In the study reported here, the experience of these cooperatives in operating their own cars was analyzed, and the comparative advantages of owning or leasing the cars was explored.

description: Recently the developments in the field of II-VI-oxides have been spectacular. Various epitaxial methods has been used to grow epitaxial ZnO layers. Not only epilayers but also sufficiently good-quality multiple quantum wells (MQWs) have also been grown by laser molecular-beam epitaxy (laser-MBE). We discuss mainly the experimental aspect of the optical properties of excitons in ZnO-based MQW heterostructures. Systematic temperature-dependent studies of optical absorption and photoluminescence in these MQWs were used to evaluate the well-width dependence and the composition dependence of the major excitonic properties. Based on these data, the localization of excitons, the influence of exciton-phonon interaction, and quantum-confined Stark effects are discussed. The optical spectra of dense excitonic systems are shown to be determined mainly by the interaction process between excitons and biexcitons. The high-density excitonic effects play a role for the observation of room-temperature stimulated emission in the ZnO MQWs. The binding energies of exciton and biexciton are enhanced from the bulk values, as a result of quantum-confinement effects.

description: Leerstehende Objekte in einer ländlichen Dorfstruktur werden mit der Zeit zu Problempunkten. Verlassene Gebäude hinterlassen in Ortszentren ein unattraktives Bild und bringen gleichzeitig ein wirtschaftliches Problem mit sich. Diese Diplomarbeit befasst sich mit der Nachnutzung von leerstehenden Objekten in der Gemeinde Schrattenthal in Niederösterreich. Durch die Auslotung von Potentialen und Möglichkeiten werden neue Nutzungskonzepte für den Pfarrhof, das ehemalige Rathaus und dem derzeitigen Kindergarten vorgeschlagen. Zusätzlich wird die Zukunft der Kellergasse Mühle behandelt. Die Konzepte der Objekte in Schrattenthal werden in drei Ausbaustufen gegliedert und anhand von Entwürfen dargestellt. Mit diesen aufbauenden Projektphasen kann eine nachhaltige und wirtschaftliche Umsetzung, die den Bedürfnissen und Anforderungen der lokalen Akteure entspricht, garantiert werden. Ergänzend dazu erfolgt die Abschätzung der erforderlichen Baukosten. Themen wie Multifunktionalität, Ökonomie, Ökologie und Barrierefreiheit sowie die Wahrung des Ortsbildes werden in den vorliegenden Visionen berücksichtigt.
description: In the course of time, vacant objects in a rural village may become problem areas. Abandoned buildings leave an unattractive image in town centers. At the same time they create economic problems. This master thesis reveals the subsequent use of vacant objects in the municipality Schrattenthal in Lower Austria. Novel development options are proposed for the vicarage, the former town hall and the current kindergarten. In addition, the future of the Kellergasse Mühle will be elaborated. The developed concepts are divided into three stages of completion and will be presented in draft status. With these stages and the estimated construction costs, a sustainable and economic realization can be envisioned for the local actors. Multifunctionality, economy, ecology and accessibility as well as the fitting within the overall appearance of the locality are considered in this master thesis.

description: PDEs with random data are investigated and simulated in the field of Uncertainty Quantification (UQ), where uncertainties or (planned) variations of coefficients, forces, domains and boundary con- ditions in differential equations formally depend on random events with respect to a pre-determined probability distribution. The discretization of these PDEs typically leads to high-dimensional (determin- istic) systems, where in addition to the physical space also the (often much larger) parameter space has to be considered. A proven technique for this task is the Stochastic Galerkin Finite Element Method (SGFEM), for which a review of the state of the art is provided. Moreover, important concepts and results are summarized. A special focus lies on the a posteriori error estimation and the derivation of an adaptive algorithm that controls all discretization parameters. In addition to an explicit residual based error estimator, also an equilibration estimator with guaranteed bounds is discussed. Under cer- tain mild assumptions it can be shown that the successive refinement produced by such an adaptive algorithm leads to a sequence of approximations with guaranteed convergence to the true solution. Nu- merical examples illustrate the practical behavior for some common benchmark problems. Additionally, an adaptive algorithm for a problem with a non-affine coefficient is shown. By transforming the original PDE a convection-diffusion problem is obtained, which can be treated similarly to the standard affine case.

description: We estimate total factor productivity in wool production spatially across benchmarked farms in four climatic areas in Eastern Australia. Estimates are decomposed into an environment-technology gap and technical efficiency relative to the production possibilities in each area. The environment-technology gap reflects the regional differences in the environment and variations in production technologies used in the wool enterprise. Significant gaps are found to exist between areas but they are relatively small in magnitude, emphasising the adaptability of the wool enterprise to environmental variability. Technical inefficiencies are also present in all areas but are larger among farmers who do not regularly receive consultancy advice in the benchmarking group. There is little variation in mean total factor productivity between the climatic areas.

description: The transition to a new low emission energy future results in a changing mix of generation and load types due to significant growth in renewable energy penetration and reduction in system inertia due to the exit of ageing fossil fuel power plants. This increases technical challenges for electrical grid planning and operation. This study introduces a new decomposition approach to account for the system security for short term planning using conventional machine learning tools. The immediate value of this work is that it provides extendable and computationally efficient guidelines for using supervised learning tools to assess first swing transient stability status. To provide an unbiased evaluation of the final model fit on the training dataset, the proposed approach was examined on a previously unseen test set. It distinguished stable and unstable cases in the test set accurately, with only 0.57% error, and showed a high precision in predicting the time of instability, with 6.8% error and mean absolute error as small as 0.0145.

description: This letter introduces ab initio study of the full activation-volume tensor of crystalline defects as a means to make contact with mechanical response experiments. We present a theoretical framework for prediction of the internal friction associated with divacancy defects and give the first ab initio value for this quantity in silicon. Finally, making connection with defect alignment studies, we give the first unambiguous resolution of the debate surrounding ab initio verification of the ground-state structure of the defect.

description: There is a wide variety of approaches to whole farm models (WFMs) including purely biophysical models as well as models that combine biological and financial elements. Our study was motivated by the notion that researchers may benefit from guidelines on the choices they must make about modelling approach, when they are interested in moving to the whole-farm scale in order to understand the impacts of management changes on farm businesses. This paper reviews 53 studies published in Agricultural Systems, including the recent development of WFMs for developing country situations. We document current approaches and develop a typology, and describe strengths and weaknesses of various approaches. Models differed in the extent to which they accounted for resource constraints, endogeneity of input levels, spatial heterogeneity, interactions between activities, inter- and intra-annual variability, and risk. Models varied in objective (profit, environment, household food security), audience and whether they used real or representative farms. We found many studies did not provide a new insight into a farming system that has general relevance outside the specifics of the case being examined, did not use sensitivity analysis or validation, and were unclear on the objective of the work and the target audience. In response to this we consider issues around the communication of this type of research, proposing guidelines for the publication of WFM papers that are well documented, clear and useful.
