description: The purpose of this paper is to understand how farm-level factors are associated with a farmer’s perceived success of Multifunctional Activities (MFAs) and desire to continue participating in MFAs. Using the responses from a survey of farmers in New England, we use logistic and ordered logistic models to determine how farm-level factors are associated with the probability of: 1) the farmer believing that his participation in MFAs is successful; 2) the farmer believing that his participation in MFAs has achieved a certain level of success; and 3) the probability that the farmer expresses a desire to continue participating in MFAs. We provide new and interesting insights into MFA success and participation by using a unique, detailed survey of New England farmers and by focusing on success as it is perceived by the farmer.

description: We address the question of radiation emission from both perfect and dispersive mirrors following prescribed relativistic trajectories. The trajectories considered are asymptotically inertial: the mirror starts from rest and eventually reverts to motion at uniform velocity. This enables us to provide a description in terms of in and out states. We calculate exactly the Bogolubov alpha and beta coefficients for a specific form of the trajectory, and stress the analytic properties of the amplitudes and the constraints imposed by unitarity. A formalism for the description of emission of radiation from a dispersive mirror is presented.

description: We use a 3D Monte Carlo radiative transfer code to study the polarimetric and photometric variability from stationary corotating interaction regions (CIR) in the wind of massive stars. Our CIRs are approximated by Archimedean spirals of higher (or lower) density formed in a spherical wind originating from the star and we also made allowance for a bright gaussian spot at the base of the CIR. Comparing results from our code to previous analytical calculations in the optically thin case, we find differences which we attribute mainly to a better estimation of the total unpolarized flux reaching the observer. In the optically thick case, the differences with the analytical calculations are much larger, as multiple scattering introduces extra complexities including occultation effects. The addition of a gaussian spot does not alter the shape of the polarization curve significantly but does create a small excess in polarization. On the other hand, the effect can be larger on the light curve and can become dominant over the resulting CIR, depending on the spot parameters and density of the wind.

description: How conventional and experimental prototypes and series created an architecture for all.

Mass housing and prefabrication shaped global modernist architecture like no other aspect of industrialised construction. This book offers a comprehensive exploration of how both conventional and experimental prototypes and series gave rise to an architecture for all and responded to crises, nation-building, and housing shortages within the context of transnational and regional research.

The book’s contributions explore partially unearthed empirical ground, such as cases from Finland and Sweden, while others offer a fresh interpretation of prefabrication’s role in the history of global architecture, notably in the USSR and Italy. The chapters’ topics encompass colonial expansion, class, international collaboration, and the achievements and setbacks of industrialised design. The authors scrutinise the cultural impact of mass housing and prefabrication, tracing this influence through exhibitions, memory culture, and typologies, ultimately concluding with an outlook on the preservation and repair of structures and their adaptation for the future.

description: Negative energy objects generally lead to instabilities and a number of other disturbing behaviors. In particular, negative energy fluxes lead to a breakdown of the classical area theorem for black hole horizons, which can lead to violations of the second law of thermodynamics. The negative energy objects that arise in string theory involve special boundary conditions which remove the perturbative instabilities. We show that they have additional special features which allow them to evade contradiction with the second law. We identify one mechanism which applies for most orientifold planes in string theory, and distinct mechanisms for the O8-plane and the AdS soliton.

description: We performed observations of the Sco-Cen F star HD 117214 aiming at a search for planetary companions and the characterization of the debris disk structure. HD 117214 was observed with the SPHERE subsystems IRDIS, IFS and ZIMPOL at optical and near-IR wavelengths using angular and polarimetric differential imaging techniques. This provided the first images of scattered light from the debris disk with a spatial resolution reaching 25 mas and an inner working angle $< 0.1''$. With the observations with IRDIS and IFS we derive detection limits for substellar companions. The geometrical parameters of the detected disk are constrained by fitting 3D models for the scattering of an optically thin dust disk. Investigating the possible origin of the disk gap, we introduced putative planets therein and modeled the planet-disk and planet-planet dynamical interactions. The obtained planetary architectures are compared with the detection limit curves. The debris disk has an axisymmetric ring structure with a radius of $0.42(\pm 0.01)''$ or $\sim45$ au and an inclination of $71(\pm 2.5)^\circ$ and exhibits a $0.4''$ ($\sim40$ au) wide inner cavity. From the polarimetric data, we derive a polarized flux contrast for the disk of $(F_{\rm pol})_{\rm disk}/F_{\rm \ast}> (3.1 \pm 1.2)\cdot 10^{-4}$ in the RI band. The fractional scattered polarized flux of the disk is eight times smaller than the fractional infrared flux excess. This ratio is similar to the one obtained for the debris disk HIP 79977 indicating that dust radiation properties are not very different between these two disks. Inside the disk cavity we achieve the high sensitivity limits on planetary companions with a mass down to $\sim 4 M_{\rm J}$ at projected radial separations between $0.2''$ and $0.4''$. We can exclude the stellar companions at a radial separation larger than 75 mas from the star.

description: Generative modeling with machine learning has provided a new perspective on the data-driven task of reconstructing quantum states from a set of qubit measurements. As increasingly large experimental quantum devices are built in laboratories, the question of how these machine learning techniques scale with the number of qubits is becoming crucial. We empirically study the scaling of restricted Boltzmann machines (RBMs) applied to reconstruct ground-state wavefunctions of the one-dimensional transverse-field Ising model from projective measurement data. We define a learning criterion via a threshold on the relative error in the energy estimator of the machine. With this criterion, we observe that the number of RBM weight parameters required for accurate representation of the ground state in the worst case - near criticality - scales quadratically with the number of qubits. By pruning small parameters of the trained model, we find that the number of weights can be significantly reduced while still retaining an accurate reconstruction. This provides evidence that over-parametrization of the RBM is required to facilitate the learning process.

Given a chart, a language model needs to not only correctly comprehend the chart (the FACT question) but also judge if the chart will be misleading to a human reader (the MIND question). Both questions have significant societal benefits. We detail the construction of the CHARTOM benchmark including its calibration on human performance.

description: We examine the role of spatial interactions in conservation easements placed on prairie pothole habitat in western Canada. One of the goals of the conservation easement program we study is to protect contiguous habitat. We identify endogenous spatial interactions among conservation easements and government protected land, independent of spatially correlated landscape features and local economic shocks that influence easement enrollment. We present evidence that easements increase the likelihood of subsequent easements on neighboring land. Government-protected land appears to have little effect on the location of conservation easements. These results imply that conservation agencies have leveraged past conservation effort to enroll more contiguous habitat in permanent easements through a combination of targeting and positive social interactions among neighboring landowners.

description: The great challenge for this research work is to show that the biases of investor behavior are predictable and may affect the coffee futures market prices. This research work uses auto-regressive conditional heteroskedasticity (ARCH) models to analyze results that cause deviations in the coffee futures market prices. The negative asymmetry coefficient of EGARCH model and the positive asymmetry coefficient of TGARCH model show the presence of the leverage effect where negative shocks have a greater impact in the volatility of returns in coffee than positive shocks. The presence of the leverage effect corroborates the Prospect Theory. Model results also show that the reactions of investors to negative information were statistically significant in the coffee futures market and suggest that Behavioral Finance might contribute to the understanding of the formation of coffee futures market prices.

description: The local magnetic field in a Penning-Malmberg trap is found by measuring the temperatures that result when electron plasmas are illuminated by microwaves pulses. Multiple heating resonances are observed as the pulse frequencies are swept. The many resonances are due to electron bounce and plasma rotation sidebands. The heating peak corresponding to the cyclotron frequency resonance is identified to determine the magnetic field. A new method for quickly preparing low density electron plasmas for destructive temperature measurements enables a rapid and automated scan of microwave frequencies. This technique can determine the magnetic field to high precision, obtaining an absolute accuracy better than $1\,\mathrm{ppm}$, and a relative precision of $26\,\mathrm{ppb}$. One important application is in situ magnetometry for antihydrogen-based tests of charge-parity-time symmetry and of the weak equivalence principle

description: The Bose-Hubbard Hamiltonian capturing the essential physics of the arrays of interacting Bose-Einstein condensates is addressed, focusing on arrays consisting of two (dimer) and three (trimer) sites. In the former case, some results concerning the persistence of mean-field features in the energy spectrum of the symmetric dimer are extended to the asymmetric version of the system, where the two sites are characterized by different on-site energies. Based on a previous systematic study of the mean-field limit of the trimer, where the dynamics is exhaustively described in terms of its fixed points for every choice of the significant parameters, an interesting mapping between the dimer and the trimer is emphasized and used as a guide in investigating the persistence of mean-field features in the rather complex energy spectrum of the trimer. These results form the basis for the systematic investigation of the purely quantum trimer extending and completing the existing mean-field analysis. In this respect we recall that, similar to larger arrays, the trimer is characterized by a non-integrable mean-field dynamics featuring chaotic trajectories. Hence, the correspondence between mean-field fixed points and quantum energy levels emphasized in the present work may provide a key to investigate the quantum counterpart of classical instability.

We study black holes possessing electric and magnetic charges, and the source of the gravitational field is electromagnetic fields obeying the logarithmic electrodynamics. This particular form of nonlinear electrodynamics is of interest because of its simplicity. Corrections to Coulomb's law and Reissner-Nordstrom solution are found. We calculate the Hawking temperature of black holes and show that second-order phase transitions occur for some parameters of the model.

Production Economics

description: For the first time, the model developed by Hayami and Herdt is applied to determine gains from modern varieties of rice in Bangladesh and the distribution of these gains between consumers and producers. The results suggest that consumers' surplus is much greater than it would have been had the high yielding crop varieties ( HYVs) not been introduced. By keeping the real price lower than it would have been otherwise, the modern varieties have tended to be income equalizing for urban consumers. The Hayami-Herdt partial model even suggests that, given the relatively inelastic demand for rice in Bangladesh, the real cash income of producers has risen slightly as a result of these new technologies. In reality, however, the impact of these changes on incomes of farmers and the distribution of income between those involved in production is more complex. It is suggested that if a less partial view is taken and if account is taken of lower cost of obtaining home-consumed produce, the increase in income may be greater. In any event, there are dangers in using such a partial model to predict the developmental consequences of technological changes affecting a staple crop, and attention needs also to be given to the possibility that the supply curve may not have the simple form and pivot in the way supposed by Hayami and Herdt. While the Hayami-Herdt model is simple to apply, it is best used as a first approximation or starting point rather than a final solution. It ignores a number of criteria that could be important in assessing new agricultural technologies, such as their impact on the variability of benefits to producers and consumers and their consequences for sustainability of production. Furthermore, the Hay-ami-Herdt model does not deal specifically with changes in factor shares in farm production. Nor does it consider the impact on income distribution of the ownership and control of critical input like irrigation and imperfection in the rural credit market. It is pointed out in our paper that the adoption of HYVs has been associated with important variations in factor shares in Bangladeshi rice production. Analysis of available farm level data indicates that the relative share of labour has fallen, suggesting an uneven distribution of gains from technological changes between the owners of non-labour resources and those of labour resources. However, the absolute share of labour has increased, and it seems that rural employment has risen as result of the new technologies.

description: The food crisis in Africa has entered our living rooms through television and the press. Why is per capita agricultural production lower now than at independence in the early 1960s? This article examines the factors responsible and outlines some solutions. Both external and internal factors have converged to create the crisis - low prices to farmers to placate vocal urban consumers, inefficient, high-cost marketing boards, governments' neglect of agriculture in favor of industry, over-valued exchange rates, lack of foreign exchange and increasing debt burdens. Externally the depressed world market decreased demand for Africa's exports and contributed to the stagnation of the economics. Drought, a population growth rate approaching 3%year and a shortage of human capital added to the crisis.

description: We propose a method of projecting the quantum states from a state space of a given geometry into another state space generated by a different geometry, taking care on the correct normalization which is crucial in interpreting the quantum theory. Thanks to this method we can define on any spatially flat FLRW spacetime states in which genuine Minkowskian parameters are measured. We use these Minkowskian states for separating the frequencies in the rest frames of the massive scalar particles defining thus the scalar rest frame vacuum. We show that this vacuum is stable on the de Sitter expanding universe where the energy is conserved. In contrast, on a spatially flat FLRW spacetime with a Milne-type scale factor this vacuum results to be dynamic, corresponding to a time-dependent rest energy interpreted as an effective mass. This dynamic vacuum give rise to a cosmological particle creation which is significant only in the early Milne-type universe considered here. Some interesting features of this new effect are pointed out in a brief analysis.

description: Ultracold neutrons (UCNs) are formidable probes in precision tests of gravity. With their negligible electric charge, dielectric moment, and polarizability they naturally evade some of the problems plaguing gravity experiments with atomic or macroscopic test bodies. Taking advantage of this fact, the qBounce collaboration has developed a technique - gravity resonance spectroscopy (GRS) - to study bound quantum states of UCN in the gravity field of the Earth. This technique is used as a high-precision tool to search for hypothetical Non-Newtonian gravity on the micrometer scale. In the present article, we describe the recently commissioned Ramsey-type GRS setup, give an unambiguous proof of principle, and discuss possible measurements that will be performed.

description: To comply with clean water goals, rural areas need to build $20 billion worth of sewage treatment facilities by July 1 of this year. Communities not in compliance may be running out of luck in hoping for Federal help. Over the next decade, the Federal Government is turning over to State and local governments much of the responsibility for financing such facilities.

description: Alternative approaches to allocating and recovering costs for water on Egyptian farms are proposed and evaluated in accordance with the societal objectives of allocative efficiency, equity of income distribution and cost recovery. A linear programming model of a study area in Egypt's northern Delta predicts farmers' response to the proposed cost-sharing instruments over a range of water supply conditions. Transactions costs for each charging instrument are estimated and incorporated into the allocative efficiency analysis. Flat land charges, supplemented by water quotas in the event of increasing water scarcity, best .achieve . societal objectives in the current and prospective Egyptian situation. Volumetric charging instruments were judged to be somewhat less desirable, due to higher tangible and intangible costs of implementation. The results highlight the importance of transactions costs, the degree of water scarcity and other governmental revenue raising policies in determining an appropriate charging mechanism.

description: Tensor decomposition is one of the well-known approaches to reduce the latency time and number of parameters of a pre-trained model. However, in this paper, we propose an approach to use tensor decomposition to reduce training time of training a model from scratch. In our approach, we train the model from scratch (i.e., randomly initialized weights) with its original architecture for a small number of epochs, then the model is decomposed, and then continue training the decomposed model till the end. There is an optional step in our approach to convert the decomposed architecture back to the original architecture. We present results of using this approach on both CIFAR10 and Imagenet datasets, and show that there can be upto 2x speed up in training time with accuracy drop of upto 1.5% only, and in other cases no accuracy drop. This training acceleration approach is independent of hardware and is expected to have similar speed ups on both CPU and GPU platforms.

description: It is often argued that public support of agricultural research is inadequate. However, the empirical papers that support this hypothesis rarely reflect formal behavioral theory capable of explaining this phenomenon. This paper presents a theory that explains underfunding, namely, that funding agencies respond too slowly to secular changes in the value of research. A model of farmer and funding agency behavior is presented, and shown to imply that actual research funding will be consistently smaller than optimal funding. The assumptions and results of the model are explained in terms of the institutional literature on public agricultural research agencies.

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.

Productivity Analysis

description: This paper investigates empirically the economy-wide effects of agricultural productivity increases in the Philippines, reporting the results of a quantitative analysis based on a general equilibrium framework. A multisectoral, price endogenous model of the Philippine economy is employed, emphasizing not only agriculture but also other production sectors with which it closely interacts, as well as the distinction between rural and urban households in their income generation and consumption patterns. Among other findings, the differential effects on the real income of rural households vis-a-vis urban households arising from increased productivity in the various components of the agricultural production sector are striking. The resulting improvements in the trade balance and national income, among other macroeconomic variables, are also relatively significant. Moreover, there are significant differences in the economy-wide effects among the four sectors of food and agriculture distinguished in the study. Particularly interesting is the highly favorable impact of rising productivity in the food processing sector on agricultural crop production and rural income, a linkage effect that has not received much attention in the development literature.

description: Entrepreneurs are credited with playing a key role in wealth creation and economic development. There has been enough focus of empirical literature on linking entrepreneurship and employment generation, reducing income disparity and contributing to balanced regional development. However, the environment catastrophe, world is facing, has made it imminent for the business to find new ways of doing business. Green Entrepreneurship, however nascent, provides a gleam of hope to in the direction of sustainable development. Growing consumer awareness and preference towards environmentally friendly products has also made embedding green concepts in business models a source of competitive advantage. This study is exploratory in nature as it offers insights into the emergence of the concept of green entrepreneurship and its role in the Indian context. Based on available literature, the study proposes a conceptual model explaining a link between various social, environmental and institutional factors and green entrepreneurship, leading to sustainable development. The study also explores current green entrepreneurship scenario in the light of opportunities and challenges by presenting the case studies of successful green ventures in India.

description: Scatterometry is a fast, indirect and nondestructive optical method for the quality control in the production of lithography masks. Geometry parameters of line gratings are obtained from diffracted light intensities by solving an inverse problem. To comply with the upcoming need for improved accuracy and precision and thus for the reduction of uncertainties, typically computationally expansive forward models have been used. In this paper we use Bayesian inversion to estimate parameters from scatterometry measurements of a silicon line grating and determine the associated uncertainties. Since the direct application of Bayesian inference using Markov-Chain Monte Carlo methods to physics-based partial differential equation (PDE) model is not feasible due to high computational costs, we use an approximation of the PDE forward model based on a polynomial chaos expansion. The expansion provides not only a surrogate for the PDE forward model, but also Sobol indices for a global sensitivity analysis. Finally, we compare our results for the global sensitivity analysis with the uncertainties of estimated parameters.

description: The recent neutrino oscillation experimental results indicate that at least one neutrino has a mass greater than 50 meV. The next generation of double-beta decay experiments will very likely have a sensitivity to an effective Majorana neutrino mass below this target. Therefore this is a very exciting time for this field of research as even null results from these experiments have the potential to elucidate the nature of the neutrino.

description: The chiral crystal is characterized by a lack of mirror symmetry and an inversion center, resulting in the inequivalent right- and left-handed structures. In the noncentrosymmetric crystal structure, the spin and momentum of electrons are locked in the reciprocal space with the help of the spin-orbit interaction. To reveal the spin textures of chiral crystals, here we investigate the spin and electronic structure in p-type semiconductor elemental tellurium with a chiral crystal structure by using spin- and angle-resolved photoemission spectroscopy. Our data demonstrate that the highest valence band crossing the Fermi level has a spin component parallel to the electron momentum around the BZ corners. Significantly, we have also confirmed that the spin polarization is reversed in the crystal with the opposite chirality. The results indicate that the spin textures of the right- and left-handed chiral crystals are hedgehog-like, leading to unconventional magnetoelectric effects and nonreciprocal phenomena.

description: Special circumstances in the agricultural sector have limited the use of comparative advantage in addressing the planner's dilemma of allocating investment between industry and agriculture and in examining the doctrine of food selfsufficiency. A three-factor model of agricultural trade, extending earlier models, is used to address some of these special circumstances and to formulate a theory of agricultural comparative advantage under changing economic conditions. Emphasis is placed on the short-run fixity of sector-specific capital stocks, the role of qualitative differences in land (natural resource) endowments, and on non-homothetic preferences. In addition to insights on agricultural comparative advantage, implications for project evaluation are considered.
