Internal Migration
Australia
Queensland

description: This paper examines the causal impact of internal migration on house price changes in Queensland – Australia’s new capital of interstate migration. We study annual housing price growth across 82 Statistical Areas Level 3 (SA3) regions between 2014 and 2019 by employing a spatial correlation approach. We also estimate the impact of the increasing share of migrants from New South Wales on the local housing markets in Queensland. The main findings are summarised as follows: (1) an annual increase in the inflow of migrants equal to 1% of a region's initial population leads to a 0.6%–0.7% annual increase in Queensland’s house prices across different empirical specifications; (2) internal migration inflow increases house prices in Greater Brisbane metropolitan area, whereas internal migration has a negative impact on housing price changes in the Rest of State regions; (3) migrants tend to move towards SA3 regions where house prices grow more slowly conditional on the local area controls and the time fixed effects; (4) the increasing share of migration from New South Wales does not have a significant effect on house price growth in Queensland. Our findings have important policy implications related to sustainable local economic development since sustainable development is, for the most part, achieved by attracting newcomers to the cities/towns and completed through the involvement of migrants in local housing and labour markets.

description: Micro-economic models posit that transaction costs isolate subsistence producers from output market shocks. We integrate microeconomic models of many heterogeneous households into a general-equilibrium model and show that supply on subsistence farms may respond, in apparently perverse ways, to changes in output market prices. Price shocks in markets for staple goods are transmitted to subsistence producers through interactions in factor markets. In the case presented, a decrease in the market price of maize reduces wages and land rents, stimulating maize production by subsistence households; however, real income of subsistence households falls.

The Dwarf Novae of Shortest Period

description: We present observations of the dwarf novae GW Lib, V844 Her, and DI UMa. Radial velocities of H-alph yield orbital periods of 0.05332 +- 0.00002 d (= 76.78 m) for GW Lib and and 0.054643 +- 0.000007 d (= 78.69 m) for V844 Her. Recently, the orbital period of DI UMa was found to be only 0.054564 +- 0.000002 d (= 78.57 m) by Fried et al. (1999), so these are the three shortest orbital periods among dwarf novae with normal-abundance secondaries. GW Lib has attracted attention as a cataclysmic binary showing apparent ZZ Ceti-type pulsations of the white dwarf primary. Its spectrum shows sharp Balmer emission flanked by strong, broad Balmer absorption, indicating a dominant contribution by white-dwarf light. Analysis of the Balmer absorption profiles is complicated by the unknown residual accretion luminosity and lack of coverage of the high Balmer lines. Our best-fit model atmospheres are marginally hotter than the ZZ Ceti instability strip, in rough agreement with recent ultraviolet results from HST. The spectrum and outburst behavior of GW Lib make it a near twin of WZ Sge, and we estimate it to have a quiescent V absolute magnitude 12. Comparison with archival data reveals proper motion of 65 +- 12 mas/yr. The mean spectrum of V844 Her is typical of SU UMa dwarf novae. We detected superhumps in the 1997 May superoutburst with superhump period = 0.05597 +- 0.00005 d. The spectrum of DI UMa appears normal for a dwarf nova near minimum light. These three dwarf novae have nearly identical short periods but completely dissimilar outburst characteristics. We discuss possible implications.

description: An inhomogeneous fluid in accelerated motion is investigated. When the velocity field $v(x)$ is not constant, the geometry viewed by a static observer is curved, as if the observer were immersed in a gravitational field. A velocity-dependent semiclassical gravitational potential is introduced, which obeys an Yukawa-type equation, written in Cartesian coordinates. The timelike and null geodesic equations are investigated. One finds that the fluid has zero energy density corresponding to the perfect fluid part but nonzero anisotropic energy density. The pressures will no longer depend on $\hbar$ for time intervals $t>>1/m$, where $m$ is the field mass.

description: Dwarf galaxies are the least massive, most abundant, and most widely distributed type of galaxies. Hence, they are key to testing theories of galaxy and Universe evolution. Dwarf galaxies sufficiently close to have their gas and stellar components studied in detail are of particular interest, because their properties and their evolution can be inferred with accuracy. This Review summarizes what is known of the stellar and chemical properties of star-forming dwarf galaxies closer than $\sim$20 Mpc. Given their low metallicity, high gas content and ongoing star formation, these objects are supposed to resemble the first galaxies that formed at the earliest epochs, and may thus represent a window on the distant, early Universe. We describe the major results obtained in the past decade on the star formation histories, chemical abundances, galaxy formation and evolution of star-forming dwarfs, and the uncertainties still affecting these results.

description: By conducting a high-frequency event study similar to Gürkaynak et al.
(2005), we find that two factors are needed to adequately capture the effects
ofmonetary policy announcements for a non-inflation targeting emerging
market economy, Malaysia. These factors are the surprise changes in
the policy rate (Overnight Policy Rate, OPR) and the information about
the future path of monetary policy. We find that the path factor has a
strong influence on long-term government bond yields, corporate bond
yields and spreads. Our findings are indicative of the view that monetary
policy communication is mostly about revealing information pertaining to
the central bank’s assessment of the economic outlook, as opposed to an
unconditional binding commitment to follow a specific policy path.

description: We present lightcurves of four binary subdwarf B stars, Ton 245, Feige 11, PG1432+159 and PG1017-086. We also present new spectroscopic data for PG1017-086 from which we derive its orbital period, P=0.073d, and the mass function, f_m = 0.0010 +/- 0.0002 solar masses. This is the shortest period for an sdB binary measured to-date. The values of P and f_m for the other sdB binaries have been published elsewhere. We are able to exclude the possibility that the unseen companion stars to Ton 245, Feige 11 and PG1432+159 are main-sequence stars or sub-giant stars from the absence of a sinusoidal signal which would be caused by the irradiation of such a companion star, i.e., they show no reflection effect. The unseen companion stars in these binaries are likely to be white dwarf stars. By contrast, the reflection effect in PG1017-086 is clearly seen. The lack of eclipses in this binary combined with other data suggests that the companion is a low mass M-dwarf or, perhaps, a brown dwarf.

description: A water-soluble extract of custard apple leaves (CALEX) was obtained and characterized using detailed spectral analytical techniques. A comprehensive corrosion mitigation performance study was undertaken to examine the CALEX as efficacious inhibitor for mild steel (MS) in a 5% HCl solution employing weight loss (WL), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and contact angle measurements. Weight loss study was conducted over the temperature range of 298–328 K at the CALEX concentration range of 10–100 ppm. With the increase in CALEX concentration in the HCl solution the inhibition efficiency (%I.E.) increased but declined with increase in temperature. EIS revealed that the Rct value increases and PDP showed the mixed-type inhibition mechanism. Surface analysis presented amelioration in the surface morphology of CALEX treated MS, revealing establishment of absorptive protective film by the different organic compounds present in CALEX. XPS technique was used to understand the chemical makeup and bonding state of the CALEX molecules with the MS surface. The contact angle measurement suggested improved hydrophobicity for the CALEX inhibited MS sample compared to uninhibited sample. The adsorption of compounds present in CALEX was observed to be in line with the Langmuir adsorption isotherm.

description: Evidence is presented in support of the “brain gain” view that the likelihood of migrating to a destination wherein the returns to human capital (schooling) are high creates incentives to acquire human capital in migrant-sending areas. In Mexico, even though internal migrants are more educated than those who stay behind, the average level of schooling in the migrant-sending villages increases with internal migration. This finding is consistent with the hypothesis that the dynamic investment effects reverse the static, depletion effects of migration on schooling. Households’ access to high-skill internal migration networks significantly increases the likelihood that children will attend school beyond the compulsory level. Access to low-skill internal networks has the opposite effect. By contrast with internal migration, migration from rural Mexico to the U.S. does not select positively on schooling, nor does it significantly influence human capital formation, even though remittances from Mexican migrants in the U.S. far outweigh remittances from internal migrants.

description: This is an extended discussion of Ref.[1], presenting a nonlinear dynamical model of quantum collapse, with randomness emerging from self-generated noise. Here we focus on a few issues: 1) the way chaos theory explains "deterministic but unpredictable" as a generic feature of nonlinear dynamics; 2) a new argument about why Bell-CHSH and GHZ experiments confirm quantum mechanics; 3) a discussion of why the heating effect predicted by CSL-type theories is not expected to happen according to our approach; 4) in looking for direct-product solutions of our nonlinear Von Neumann equation, we use a parametrization different from that used in Ref.[1], allowing better insight to the locality issue.

description: The availability of immigrant farm-workers from Mexico is a critical factor affecting the fresh fruit and vegetable sector in the United States. This paper uses a retrospective panel data set from rural Mexico to examine the impact of the North American Free Trade Agreement and the Immigration Reform and Control Act on the supply of migrant labor to the United States. We find that, in contrast to policy expectations, both policies were associated with an increase in migration to U.S. farm jobs from rural Mexico.
Pixel Detectors for Particle Detection and Imaging Applications

description: Semiconductor pixel detectors offer features for the detection of radiation which are interesting for particle physics detectors as well as for imaging e.g. in biomedical applications (radiography, autoradiography, protein crystallography) or in Xray astronomy. At the present time hybrid pixel detectors are technologically mastered to a large extent and large scale particle detectors are being built. Although the physical requirements are often quite different, imaging applications are emerging and interesting prototype results are available. Monolithic detectors, however, offer interesting features for both fields in future applications. The state of development of hybrid and monolithic pixel detectors, excluding CCDs, and their different suitability for particle detection and imaging, is reviewed.

description: The supply of immigrant workers from Mexico is critical to both agricultural and non-agricultural sectors in the United States. Approximately one half of all Mexican immigrants are females who typically are employed in positions that have minimal legal status requirements, e.g., domestic services and clerical and agricultural jobs. In the past two decades, the United States implemented policy reforms motivated in large part by the desire to curtail Mexico-to-U.S. migration. Despite the large female share and differences in the sector of employment of female and male Mexican immigrants, there has been no effort, to our knowledge, to formally test for gender and employment sector differences in the impact of policy shocks on migrant flows. This paper utilizes data from the 2003 Mexico National Rural Household Survey to econometrically test the effects of U.S. immigration and trade reforms on the gender and employment sector-destination of rural Mexico-to-U.S. migrants. Findings indicate that U.S. immigration and trade policies are both gender and employment-sector specific. Female migration is more sensitive than male migration to immigration reforms and other policy shocks. We also find evidence that past migration by females has little effect on male migration, and vice versa.

household survey

description: An experiment using a representative survey of the German population shows that letting respondents report a number rather than asking them to choose from a list of predefined ranges lowers the response rate for both perceived past and expected inflation and decreases (increases) reported past (expected) inflation. Income, education, gender, objective and subjective knowledge about monetary policy, and political affiliation affect the effect’s size but not its sign. East and West German respondents who were 15 or older when the Berlin Wall fell have reactions different from those who were younger at that time, which supports the ‘impressionable years’ hypothesis based on different inflation experiences.

description: We consider a system of single- or double integrator agents playing a generalized Nash game over a network, in a partial-information scenario. We address the generalized Nash equilibrium seeking problem by designing a fully-distributed dynamic controller, based on continuous-time consensus and primal-dual gradient dynamics. Our main technical contribution is to show convergence of the closed-loop system to a variational equilibrium, under strong monotonicity and Lipschitz continuity of the game mapping, by leveraging monotonicity properties and stability theory for projected dynamical systems.

description: This article investigates similarities and differences between gold and four
cryptocurrencies (Bitcoin, Ethereum, Bitcoin Cash and Litecoin). To do so,
we estimate a system-GARCH-in-mean with respect to four determinants for
the period starting 7/18/2014 at earliest until 7/12/2021. We find that, first,
liquidity premia are less important. Second, volatility premia exist in either
gold and cryptocurrencies. Third, the response of cryptocurrencies to ex-
change rate changes is more pronounced than for gold at least if developing
countries are included. Fourth, gold exhibits a safe haven status, while cryptocurrencies do not. So those cannot be seen as a store of value but rather as speculative assets.

description: Recognizing that people value employment not only to earn income to satisfy their consumption needs, but also as a means to gain socio-psychological (nonpecuniary) benefits, we show that once nonpecuniary work incentives are incorporated into standard labor supply theory, (i) the wage rate under-estimates (over-estimates) the true value of nonwork/leisure time when work has nonpecuniary benefits (costs), (ii) nonpecuniary benefits can be a substitute for monetary wages as work incentives, (iii) at very low wage rates, work can become a net source of utility, and (iii) the shape of labor supply curve differs from standard theory. We also identify conditions under which a greater nonpecuniary work incentive generates a larger individual labor supply, and examine the effects of non-wage income on labor supply both for paid and voluntary work.

description: We investigate the thermodynamics of the one-dimensional t-J model using transfer matrix renormalization group (TMRG) algorithms and present results for quantities like particle number, specific heat, spin susceptibility and compressibility. Based on these results we confirm a phase diagram consisting of a Tomonaga-Luttinger liquid (TLL) phase for small J/t and a phase separated state for J/t large. Close to phase separation we find a spin-gap (Luther-Emery) phase at low densities consistent with predictions by other studies. At the supersymmetric point we compare our results with exact results from the Bethe ansatz and find excellent agreement. In particular we focus on the calculation of correlation lengths and static correlation functions and study the crossover from the non-universal high T lattice into the quantum critical regime. At the supersymmetric point we compare in detail with predictions by conformal field theory (CFT) and TLL theory and show the importance of logarithmic corrections.

Properties of two-temperature magnetized advective accretion flow around rotating black hole

description: We study the two-temperature magnetized advective accretion flow around the Kerr black holes. During accretion, ions are heated up due to viscous dissipation, and when Coulomb coupling becomes effective, they transfer a part of their energy to the electrons. On the contrary, electrons lose energy due to various radiative cooling processes, namely bremsstrahlung, synchrotron, and Comtonization processes, respectively. To account for the magnetic contribution inside the disc, we consider the toroidal magnetic fields which are assumed to be dominant over other components. Moreover, we adopt the relativistic equation of state to describe the thermal characteristics of the flow. With this, we calculate the global transonic accretion solutions around the rotating black holes. We find that accretion solution containing multiple critical points may harbor shock wave provided the standing shock conditions are satisfied. Further, we investigate the shock properties, such as shock location ($x_s$) and compression ratio ($R$) that delineate the post-shock corona (hereafter PSC) and find that the dynamics of PSC is controlled by the flow parameters, such as accretion rate (${\dot m}$) and magnetic fields ($β$, defined as the ratio of gas pressure to the magnetic pressure), etc. Finally, we calculate the emission spectra of the accretion flows containing PSC and indicate that both ${\dot m}$ and $β$ play the pivotal roles in explaining the spectral state transitions commonly observed for black hole X-ray binaries.

description: Information, mainly from the granitic and silicic volcanic rocks in the Stawell, Bendigo and Melbourne structural zones in the state of Victoria, shows that the sources of both the S- and I-type rocks of the Stawell and Bendigo zones (SBZ) contrast in ages and chemistry with the sources of similar granitic rocks in the Melbourne Zone, consistent with the absence of the mainly Proterozoic Selwyn Block beneath most of the SBZ. Below a mid-crustal décollement in the SBZ, the crust is evidently highly variable and possibly includes thinned Proterozoic crust. There is geochronological evidence for ca 400 and ca 370 Ma granulite-grade metamorphic events here, and, after this double bout of metamorphism, and depletion in the silicic melt component, the constituents of the entire deep crust of the SBZ would have densities similar to those of overlying, much lower-grade Cambrian metabasaltic to boninitic rocks. Thus, granitic magmas may have formed here by partial melting of a variety of rock types, probably with back-arc affinities, with ages that may extend back to the Proterozoic. Therefore, the basement of the SBZ is unlikely to consist solely of thick ocean-floor rocks, as in some current interpretations.KEY POINTSThe sources of the Devonian granitic rocks of the Stawell and Bendigo zones (SBZ) contrast in ages and chemistry with those of the Melbourne Zone granites.Two Devonian granulite-facies events left the melt-depleted deep SBZ crust with densities similar to those of overlying Cambrian metabasaltic rocks.The SBZ Devonian granitic magmas probably formed by partial melting of heterogeneous Proterozoic to Cambrian arc-related crust, below the mid-crustal décollement.

description: Single W boson production in electron-positron collisions is studied with the L3 detector at centre-of-mass energies between 192 GeV and 209 GeV. Events with two acoplanar hadronic jets or a single energetic lepton are selected, and the single W cross section is measured. Combining the results with measurements at lower centre-of-mass energies, the ratio of the measured cross section to the Standard Model expectation is found to be 1.12^{+0.11}_{-0.10}+/-0.03. From all single W data, the WWgamma gauge coupling parameter kappa_gamma is measured to be 1.116^{+0.082}_{-0.086}+/-0.068.

Resource /Energy Economics and Policy

description: We assume that people value employment not only to earn income to satisfy their consumption needs but also as a means of community/social involvement that provides socio-psychological (non-pecuniary) benefits. We show that the latter incentive can encourage full employment harvesting resources and explain why poor resource-based communities may exhaust a natural resource in a finite time even if there is a sustainable path of resource consumption available. We show that communities could sustain their natural resources by using outside-the-community employment and economic diversification, but, to be effective, such policies must ensure that the outside wage rate and the initial capital stock are above certain minimum levels, which will be higher the longer these policies are delayed.

CTL killing requires focused secretion of cytotoxic compounds from lytic granules. This process is known as degranulation. In this study, I aimed to establish the CRISPR-Cas9 gene editing technology in primary T cells and to optimise screening approaches to identify regulators of CTL killing. The first half of the thesis focuses on primary mouse CTL. The CRISPR technology was successfully optimised in CTL using Cas9-ribonucleoprotein complexes resulting in efficient CRISPR-mediated loss of target proteins. Genes encoding known mediators of CTL cytotoxicity, $\it{Rab27a}$, $\it{Munc13-4}$ and $\it{Prf1}$, were targeted using CRISPR. The resulting samples were used to establish a flow cytometry-based assay that simultaneously measures CTL degranulation and target cell death. This assay enabled me to screen for mediators of CTL killing, while providing mechanistic insight by detecting degranulation. The screen was informed by a transcriptomic study that compared naive and effector CD8 T cells. 1803 significantly upregulated differentially expressed genes [log2(fold change)>2] were identified. Functional annotation analysis and literature research were used to select genes for the targeted CRISPR screen, which highlighted the importance of HIF-1$\alpha$ and NFIL3 in CTL killing. The second half of the thesis focuses on primary human CTL. The combined degranulation and killing assay was further validated using patient-derived CTL, indicating its potential as a diagnostic test. I showed that the assay is suitable for mid-sized screens using a library of 64 compounds targeting the NF-$\kappa$B signalling pathway. Further opportunities for increasing the scale of this screening technique are discussed. Finally, I successfully tested CRISPR using Cas9-ribonucleoprotein complexes in the human system. Additionally, stable Cas9 expression through lentiviral transduction was explored in primary CTL and related cell lines. This has the potential to allow selection of cells expressing the CRISPR machinery, providing a cleaner experimental system and the possibility of large-scale screening approaches. In summary, the techniques established in this thesis will be valuable for studying the genetics underlying CTL killing and the combined degranulation and killing assay furthermore shows great potential for diagnostic purposes.

description: The large interest in chiral magnetic structures for realization of nanoscale magnetic storage or logic devices has necessitated methods which can quantify magnetic interactions at the atomic scale. To overcome the limitations of the typically used current-based sensing of atomic-scale exchange interactions, a force-based detection scheme is highly advantageous. Here, we quantify the atomic-scale exchange force field between a ferromagnetic tip and a cycloidal spin spiral using our developed combination of current and exchange force detection. Compared to the surprisingly weak spin polarization, the exchange force field is more sensitive to atomic-scale variations in the magnetization. First-principles calculations reveal that the measured atomic-scale variations in the exchange force originate from different contributions of direct and indirect (Zener) type exchange mechanisms, depending on the chemical tip termination. Our work opens the perspective of quantifying different exchange mechanisms of chiral magnetic structures with atomic-scale precision using 3D magnetic exchange force field measurements.

description: With the advent of more powerful Quantum Computers, the need for larger Quantum Simulations has boosted. As the amount of resources grows exponentially with size of the target system Tensor Networks emerge as an optimal framework with which we represent Quantum States in tensor factorizations. As the extent of a tensor network increases, so does the size of intermediate tensors requiring HPC tools for their manipulation. Simulations of medium-sized circuits cannot fit on local memory, and solutions for distributed contraction of tensors are scarce. In this work we present RosneT, a library for distributed, out-of-core block tensor algebra. We use the PyCOMPSs programming model to transform tensor operations into a collection of tasks handled by the COMPSs runtime, targeting executions in existing and upcoming Exascale supercomputers. We report results validating our approach showing good scalability in simulations of Quantum circuits of up to 53 qubits.

description: Pancreatic islet transplantation is a curative treatment for diabetes but access to this therapy is limited by the availability of islets. Long-term cryopreservation of islets could partially address this limitation but current cryopreservation protocols, which use the toxic cryoprotectant dimethyl sulphoxide (DMSO), achieve suboptimal cryosurvival and are not clinically used. The aim of this project was to develop an improved and clinically-relevant method for cryopreservation of islets. The project examined the efficacy of the non-toxic cryoprotectant trehalose in combination with (1) membrane-permeabilising biopolymers PP-50 and PP-75 to increase intracellular uptake, and (2) antioxidants MitoQ and salidroside to reduce cryopreservation-induced oxidative stress. Due to the complex architecture of pancreatic islets, human mononuclear cells were first used to optimise the use of permeabilising polymers. Current methods of viability assessment were critically examined and improved, followed by systematic screening of cryopreservation conditions. The efficacy of promising cryopreservation protocols were subsequently confirmed for mouse pancreatic islets using viability and functional assays. PP-50 and PP-75 polymers were shown to be unsuitable for trehalose-based cryopreser- vation of mononuclear cells and islets due to potential toxicity and need for long incubation. Investigation of diffusion kinetics demonstrated that a minimal incubation time of 6 h at 37 °C is required to enable diffusion of solutes into the islet core. This finding implies that current clinical viability assessment protocols only survey the periphery of islets. A range of imaging modalities were used to confirm that islet core viability can be dramatically different from the islet periphery. Using these insights, a novel cryopreservation protocol was developed in which islets are pre-incubated for 6 h at 37 °C with trehalose and antioxidants, followed by addition of DMSO, resulting in significantly greater viability of cryopreserved islets. In conclusion, this study identified important limitations of the current cryobiological viability assessment of mononuclear cells and pancreatic islets. Permeabilising biopolymers did not improve trehalose-based cryopreservation in primary cells. An improved method for cryopreservation of pancreatic islets was developed which combines DMSO and trehalose in a novel manner and can be further improved by addition of antioxidants.

Risk and Uncertainty

description: By shrinking the available menu of loan contracts, asymmetric information can result in two types of nonprice rationing in credit markets. The first is conventional quantity rationing. The second is ‘risk rationing.’ Risk rationed agents are able to borrow, but only under relatively high collateral contracts that offer them lower expected well-being than a safe, reservation rental activity. Like quantity rationed agents, credit markets do not perform well for the risk rationed. While the incidence of conventional quantity rationing is straightforward (low wealth agents who cannot meet minimum endogenous collateral requirements are quantity rationed), the incidence of risk rationing is less straightforward. Increases in financial wealth, holding productive wealth constant, counter intuitively result in the poor becoming entrepreneurs and the wealthy becoming workers. While this counterintuitive puzzle has been found in the literature on wealth effects in principal-agent models, we show that a more intuitive pattern of risk rationing results if we consider increases in productive wealth. Empirical evidence drawn from four country studies corroborates the implications of the analysis, showing that agents with low levels of productive wealth are risk rationed, and that their input and output levels mimic those of low productivity quantity rationed firms.
A single saddle model for the beta-relaxation in supercooled liquids

description: We study the Langevin equation for a single harmonic saddle as an elementary model for the beta-relaxation in supercooled liquids close to Tc. The input of the theory is the spectrum of the eigenvalues of the dominant stationary points at a given temperature. We prove in general the existence of a time-scale t_eps, which is uniquely determined by the spectrum, but is not simply related to the fraction of negative eigenvalues. The mean square displacement develops a plateau of length t_eps, such that a two-step relaxation is obtained if t_eps diverges at Tc. We analyze the specific case of a spectrum with bounded left tail, and show that in this case the mean square displacement has a scaling dependence on time identical to the beta-relaxation regime of Mode Coupling Theory, with power law approach to the plateau and power law divergence of t_eps at Tc.

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: This paper suggests that a Leontief type input-output technique has an unrealized potential as the basis for efficient data systems. A model in the process of development for the UK livestock, meat, and meat products industry is used as an example. An expansive discussion of agricultural data systems is beyond the scope of this paper, but a thorough examination of the principal issues and an extensive bibliography are given by Barnard.
