Structural Variations of Agriculture in the Pacific

Subjects: Agricultural and Food Policy
Production Economics

description: Agricultural shares of output and employment in thirteen Pacific basin countries are analyzed with reference to a global baseline for 1980. Per-capita output parity ratios are lower in the ASEAN, ANICs, and Japan as compared to their trading partners in North America and Oceania. Wide differences in land-labor ratios influence the directions of technological change, economies of scale, and dynamic comparative advantage. Differential changes in the partial productivities of land and labor between the high and middle income economies suggest that there has been a narrowing of the gap in land productivities and a widening of the gap in labor productivities across the Pacific. The implication is that there has been a regressive international impact on wages for farm labor. Further, since agriculture's share of land resources does not tend to fall as fast as its share of output and labor, increasing structural imbalance in terms of differential land rents to agriculture vis-a-vis non-agriculture results in greater adjustment pressures on the property and derived institutional systems that control natural resource allocation decisions. The results are consistent with the heavy adjustment burdens that agriculture and developing economies have been bearing as a result of expanding trade and capital flows, and the need to focus more attention on the structure, functioning, and performance of the different institutional systems that control resource allocation decisions in these countries.

description: In the current standard viewpoint small black holes are believed to emit radiation as black bodies at the Hawking temperature, at least until they reach Planck size, after which their fate is open to conjecture. A cogent argument against the existence of remnants is that, since no evident quantum number prevents it, black holes should radiate completely away to photons and other ordinary stable particles and vacuum, like any unstable quantum system. Here we argue the contrary, that the generalized uncertainty principle may prevent their total evaporation in exactly the same way that the uncertainty principle prevents the hydrogen atom from total collapse: the collapse is prevented, not by symmetry, but by dynamics, as a minimum size and mass are approached.

Risk and Uncertainty

description: Risk-taking preferences were elicited from small semi-commercial farmers in Northern Thailand using an experimental procedure that included real manetar:; payoffs of meaningful magnitudes. A total of five sets of lotteries with increasing payoffs were offered. The farmers were found to be risk averters, and their preferences conformed to the hypothesis of increasing (nondecreasing) partial relative risk aversion. Using regression analysis, farmers' expected variation of rice yields and farm size were found to be directly related to a decrease in risk aversion, while the extent of multiple cropping, availability of non-land household assets, and tested mathematical ability were found to be indirectly related to a decrease in risk aversion. The variables expected variation of rice prices, farmers' age, and tested abstract ability scores were not related to risktaking preferences.

description: Over the decades to 1980 agricultural marketing and input supply systems came increasingly under official monopolies. Dissatisfaction with the incentives offerred to producers and with the costs to governments has sparked interest in reform. Practicable ways of introducing more competition and mobilizing potential individual initiatives are presented. Obstacles to progress in this direction include political commitments of governments, ethnic concerns and patronage interests. External aid can help ease these constraints.

description: We report proton temperature anisotropy variations in the inner heliosphere with Parker Solar Probe (PSP) observations. Using a linear fitting method, we derive proton temperature anisotropy with temperatures measured by the Solar Probe Cup (SPC) from the SWEAP instrument suite and magnetic field observations from the FIELDS instrument suite. The observed radial dependence of temperature variations in the fast solar wind implies stronger perpendicular heating and parallel cooling than previous results from Helios measurements made at larger radial distances. The anti-correlation between proton temperature anisotropy and parallel plasma beta is retained in fast solar wind. However, the temperature anisotropies of the slow solar wind seem to be well constrained by the mirror and parallel firehose instabilities. The perpendicular heating of the slow solar wind inside 0.24 AU may contribute to its same trend up against mirror instability thresholds as fast solar wind. These results suggest that we may see stronger anisotropy heating than expected in inner heliosphere.

description: We investigate the market microstructure of the wholesale markets for rice in India. We propose a general method of splitting the wholesale bid-ask spread into its three constituent components: the order processing costs, the adverse information costs and the inventory holding costs. The bid-ask spread reflects the extent of information asymmetry and order imbalance in the market place. However, the dynamics of the bid-ask spread can only be understood in terms of the movement of its components; hence the importance of isolating these components. We use Zellner's seemingly unrelated regressions to split the bid-ask spread into the three components in the rice markets of 14 major centers in India. The results are then linked to the production and consumption patterns in the market areas covered by these centers. © 1999 Elsevier Science B.V. All rights reserved.
Abundance Estimates for 16 Elements in 6 Million Stars from LAMOST DR5 Low-Resolution Spectra

description: We present the determination of stellar parameters and individual elemental abundances for 6 million stars from $\sim$8 million low-resolution ($R\sim1800$) spectra from LAMOST DR5. This is based on a modeling approach that we dub $The$ $Data$--$Driven$ $Payne$ ($DD$--$Payne$), which inherits essential ingredients from both {\it The Payne} \citep{Ting2019} and $The$ $Cannon$ \citep{Ness2015}. It is a data-driven model that incorporates constraints from theoretical spectral models to ensure the derived abundance estimates are physically sensible. Stars in LAMOST DR5 that are in common with either GALAH DR2 or APOGEE DR14 are used to train a model that delivers stellar parameters ($T_{\rm eff}$, $\log g$, $V_{\rm mic}$) and abundances for 16 elements (C, N, O, Na, Mg, Al, Si, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, and Ba) when applied to LAMOST spectra. Cross-validation and repeat observations suggest that, for ${\rm S/N}_{\rm pix}\ge 50$, the typical internal abundance precision is 0.03--0.1\,dex for the majority of these elements, with 0.2--0.3\,dex for Cu and Ba, and the internal precision of $T_{\rm eff}$ and $\log g$ is better than 30\,K and 0.07\,dex, respectively. Abundance systematics at the $\sim$0.1\,dex level are present in these estimates, but are inherited from the high-resolution surveys' training labels. For some elements, GALAH provides more robust training labels, for others, APOGEE. We provide flags to guide the quality of the label determination and to identify binary/multiple stars in LAMOST DR5. The abundance catalogs are publicly accessible via \href{url}{http://dr5.lamost.org/doc/vac}.

description: The linear subspace hypothesis (Bolukbasi et al., 2016) states that, in a language model's representation space, all information about a concept such as verbal number is encoded in a linear subspace. Prior work has relied on auxiliary classification tasks to identify and evaluate candidate subspaces that might give support for this hypothesis. We instead give a set of intrinsic criteria which characterize an ideal linear concept subspace and enable us to identify the subspace using only the language model distribution. Our information-theoretic framework accounts for spuriously correlated features in the representation space (Kumar et al., 2022). As a byproduct of this analysis, we hypothesize a causal process for how a language model might leverage concepts during generation. Empirically, we find that LEACE (Belrose et al., 2023) returns a one-dimensional subspace containing roughly half of total concept information under our framework for verbal-number. Our causal intervention for controlled generation shows that, for at least one concept, the subspace returned by LEACE can be used to manipulate the concept value of the generated word with precision.

description: Using a linear-programming model of farming systems in northern Malawi, the conditions under which peasant farmhousehold models may need to allow for embedded risk are investigated. Tactical, sequential responses to uncertainty are found to be more important to labour-scarce households with limited access to capital and to credit markets. Compared with semi-sequential programming, discrete stochastic programming (DSP) provided more efficient solutions for problems involving embedded risk. There may be intuitive advantages in presenting results from DSP models in terms of a semisequential strategy. © 1999 Elsevier Science B.V. All rights reserved.

description: Second harmonic generation (SHG) on the pyrochlore metal Cd2Re2O7 indicates the presence of three order parameters setting in below an inversion breaking transition. Here, we explore a possible structural explanation and relate it not only to the SHG data, but also to neutron and x-ray diffraction, where we find that such a structural scenario can explain certain reflection extinctions observed in single crystal x-ray data. From this analysis, we suggest future experiments that could be done to resolve this matter. Finally, we comment on the Landau-violating nature of the inversion breaking transition and its relation to similar phenomena observed in improper ferroelectrics.

description: The objectives of this study are to examine both the significance of the impact of farmers' perceptions regarding new technology for the adoption decision and how perceptions themselves are influenced by the decision to adopt new technology. The study is based on data from 96 wheat farms in the Moret and Jiru woreda (district) of Ethiopia. The probit approach is used to analyse the adoption decision, while the variables relevant to farmers' perceptions are modelled using the ordered probit methodology. A simultaneous equations model combining the probit and ordered probit approaches provides a useful approach to modelling the two-way relationship between perception and adoption. Variables such as farm size, farm income and soil type have a key role to play in the model. Perception is measured by eight different components and as there is a strong collinearity among these various measures, a principal components analysis is attempted to draw the best possible linear combination of variables. © 1999 Elsevier Science B.V.

description: Motivation Computational analysis of large-scale metagenomics sequencing datasets have proven to be both incredibly valuable for extracting isolate-level taxonomic, and functional insights from complex microbial communities. However, due to an ever-expanding ecosystem of metagenomics-specific methods and file-formats, designing studies which implement seamless and scalable end-to-end workflows, and exploring the massive amounts of output data have become studies unto themselves. One-click bioinformatics pipelines have helped to organize these tools into targeted workflows, but they suffer from general compatibility and maintainability issues.
Methods To address the gap in easily extensible yet robustly distributable metagenomics workflows, we have developed a module-based metagenomics analysis system: “Core Analysis Metagenomics Pipeline” (CAMP), written in Snakemake, a popular workflow management system, along with a standardized module and working directory architecture. Each module can be run independently or conjointly with a series of others to produce the target data format (ex. shortread preprocessing alone, or short-read preprocessing followed by de novo assembly), and outputs aggregated summary statistics reports and semi-guided Jupyter notebook-based visualizations.
Results We have applied CAMP to a set of ten metagenomics samples to demonstrate how a modular analysis system with built-in data visualization at intermediate steps facilitates rich and seamless inter-communication between output data from different analytic purposes.

description: The highly frustrated Heisenberg antiferromagnet on Checkerboard and Pyrochlore lattices is subject to strong quantum fluctuations. This problem is amenable to the Contractor Renormalization (CORE) algorithm, which systematically computes the effective interactions in a basis of local cluster eigenstates. CORE was recently used to derive the Plaquette Boson-Fermion model for the square lattice Hubbard model (cond-mat/0108087). For the spin half Checkerboard and Pyrochlore cases, we find singlet ground states which break lattice symmetry, and a gap to spin one excitations. The low excitations are singlets, coupled by Ising like interactions at an emergent low energy scale, which for the Pyrochlore is about 1% of the Heisenberg exchange. We discuss low temperature thermodynamics and new interpretations of finite size numerical data. We argue that our results are common to many models of quantum frustration.

description: Starting from the analysis of Valentina Prosperi’s recent book Omero sconfitto. Ricerche sul mito di Troia dall’Antichità al Rinascimento (Roma 2013), the paper develops some considerations about the current state of research on the reception of the Trojan myth in Western culture. Four main contexts are outlined: the reflections on Greek identity by the intellectuals of the so-called Second Sophistic in the Roman imperial period (1st-3rd century); the cultural shift of Late Antique translators (4th-6th century), and the effects of their peculiar choices on the transmission of ancient texts; the renewed interest in the stories of Troy in the Western Middle Ages, especially in France and Italy, from the 12th to the 14th century; and, finally, the importance of ancient myth and epic poetry for the literary self-consciousness of Italian Renaissance humanists and writers of the Quattrocento and Cinquecento. The author stresses the long-lasting importance of the ancient literary accounts of the Trojan war in shaping the cultural identity of Western civilization, and especially their role as models for the two genres of historiography and fiction, often far more closely interrelated with one another than we expect.

We prove that any right-angled Coxeter group that acts geometrically on the Croke-Kleiner spaces acts with $π/2$ angles between reflecting axes, while the quasi-isometric right-angled Artin group can act with angles that are any real number in the range $(0, π/2]$. The contrast between the two examples shows that in this case a right-angled Coxeter group is geometrically more "rigid" than its quasi isometric counterpart.

Data for the $p(\vec e,e'p)π^o$ reaction were taken at Jefferson Lab with the CEBAF Large Acceptance Spectrometer (CLAS) using longitudinally polarized electrons at an energy of 1.515 GeV. For the first time a complete angular distribution was measured, permitting the separation of different non-resonant amplitudes using a partial wave analysis. Comparison with previous beam asymmetry measurements at MAMI indicate a deviation from the predicted $Q^2$ dependence of $σ_{LT^{\prime}}$ using recent phenomenological models.

description: We report the first detection of a time-dependent, dust-scattered X-ray halo around a gamma-ray burst. GRB 031203 was observed by XMM-Newton starting six hours after the burst. The halo appeared as concentric ring-like structures centered on the GRB location. The radii of these structures increased with time as t^{1/2}, consistent with small-angle X-ray scattering caused by a large column of dust along the line of sight to a cosmologically distant GRB. The rings are due to dust concentrated in two distinct slabs in the Galaxy located at distances of 880 and 1390 pc, consistent with known Galactic features. The halo brightness implies an initial soft X-ray pulse consistent with the observed GRB.

description: Applying reinforcement learning (RL) to real-world problems is often made challenging by the inability to interact with the environment and the difficulty of designing reward functions. Offline RL addresses the first challenge by considering access to an offline dataset of environment interactions labeled by the reward function. In contrast, Preference-based RL does not assume access to the reward function and learns it from preferences, but typically requires an online interaction with the environment. We bridge the gap between these frameworks by exploring efficient methods for acquiring preference feedback in a fully offline setup. We propose Sim-OPRL, an offline preference-based reinforcement learning algorithm, which leverages a learned environment model to elicit preference feedback on simulated rollouts. Drawing on insights from both the offline RL and the preference-based RL literature, our algorithm employs a pessimistic approach for out-of-distribution data, and an optimistic approach for acquiring informative preferences about the optimal policy. We provide theoretical guarantees regarding the sample complexity of our approach, dependent on how well the offline data covers the optimal policy. Finally, we demonstrate the empirical performance of Sim-OPRL in different environments.

description: It is well known that massive black holes may form through the gravitational collapse of a massive astrophysical body. Less known is the fact that a black hole can be produced by the quantum process of pair creation in external fields. These black holes may have a mass much lower than their astrophysical counterparts. This mass can be of the order of Planck mass so that quantum effects may be important. This pair creation process can be investigated semiclassically using non-perturbative instanton methods, thus it may be used as a theoretical laboratory to obtain clues for a quantum gravity theory. In this work, we review briefly the history of pair creation of particles and black holes in external fields. In order to present some features of the euclidean instanton method which is used to calculate pair creation rates, we study a simple model of a scalar field and propose an effective one-loop action for a two-dimensional soliton pair creation problem. This action is built from the soliton field itself and the soliton charge is no longer treated as a topological charge but as a Noether charge. The results are also valid straightforwardly to the problem of pair creation rate of domain walls in dimensions greater than 2.

description: As the first generation of laser interferometric gravitational wave detectors near operation, research and development has begun on increasing the instrument's sensitivity while utilizing the existing infrastructure. In the Laser Interferometer Gravitational Wave Observatory (LIGO), significant improvements are being planned for installation in ~2007, increasing strain sensitivity through improved suspensions and test mass substrates, active seismic isolation, and higher input laser power. Even with the highest quality optics available today, however, finite absorption of laser power within transmissive optics, coupled with the tremendous amount of optical power circulating in various parts of the interferometer, result in critical wavefront deformations which would cripple the performance of the instrument. Discussed is a method of active wavefront correction via direct thermal actuation on optical elements of the interferometer. A simple nichrome heating element suspended off the face of an affected optic will, through radiative heating, remove the gross axisymmetric part of the original thermal distortion. A scanning heating laser will then be used to remove any remaining non-axisymmetric wavefront distortion, generated by inhomogeneities in the substrate's absorption, thermal conductivity, etc. A proof-of-principle experiment has been constructed at MIT, selected data of which are presented.

title: Le metamorfosi di Circe: dea, maga e femme fatale
Creators: name: Berti, Irene
Publisher: name: Status Quaestionis
Year: 2015

description: The myth of the encounter between Odysseus and Circe, first attested in the Odyssey, was very popular in and after Antiquity, and it inspired poets, artists and philosophers. In most cases, the post-Homeric Circe is transformed from an ambiguous, but fundamentally positive creature, into an increasingly negative one. Starting her “career” as a Homeric goddess, she quickly turns into a witch and into a seducer. This essay focuses on the reception of the figure of Circe in two periods, the Renaissance and the belle époque, during which she enjoyed considerable success, as an enchantress in the former, and as a femme fatale in the latter.

description: Using the recently proposed formalism for Lambda<0 quantum gravity in 2+1 dimensions we study the process of black hole production in a collision of two point particles. The creation probability for a BH with a simplest topology inside the horizon is given by the Liouville theory 4-point function projected on an intermediate state. We analyze in detail the semi-classical limit of small AdS curvatures, in which the probability is dominated by the exponential of the classical Liouville action. The probability is found to be exponentially small. We then argue that the total probability of creating a horizon given by the sum of probabilities of all possible internal topologies is of order unity, so that there is no exponential suppression of the total production rate.

description: This paper aims to analyse the presence of figures and themes coming from the Classical heritage in the Japanese manga production. This review focuses mainly on how the manga-artists use such characters in order to identify and depict otherness: the works that are taken under consideration are mainly comics dating to 1970s, in which it is possible to follow an evolution of this production. The Author tries also to present a social and political explication of this phenomenon, based upon a brief analysis of how these theme could be connected to the evolution of the cultural and military relationship between Japan and the West ypical way while the latter are strongly reinterpreted. So the purpose of this paper is to understand the reasons for this different use of the past.

description: The article aims to analyse the reception of classical antiquity and of the ancient religions in a comic by Luca Enoch: Gea. Originally published by Sergio Bonelli Editore in the late 1990s, Gea is an unicumfor the Bonellian standards starting from its editorial format and its narrative structure. But the real touch of originality can be identified in its main themes, which are unusual for a “popular comic” – sexuality, social problems, political matters, etc. – and in the way how the Author uses the classical heritage and the ancient religions in two different modes. The former is presented in a traditional and stereotypical way while the latter are strongly reinterpreted. So the purpose of this paper is to understand the reasons for this different use of the past.

description: The need for processing at the edge the increasing amount of data that is being produced by multitudes of sensors has led to the demand for mode power efficient computational systems, by exploring alternative computing paradigms and technologies. Neuromorphic engineering is a promising approach that can address this need by developing electronic systems that faithfully emulate the computational properties of animal brains. In particular, the hippocampus stands out as one of the most relevant brain region for implementing auto associative memories capable of learning large amounts of information quickly and recalling it efficiently. In this work, we present a computational spike-based memory model inspired by the hippocampus that takes advantage of the features of analog electronic circuits: energy efficiency, compactness, and real-time operation. This model can learn memories, recall them from a partial fragment and forget. It has been implemented as a Spiking Neural Networks directly on a mixed-signal neuromorphic chip. We describe the details of the hardware implementation and demonstrate its operation via a series of benchmark experiments, showing how this research prototype paves the way for the development of future robust and low-power mixed-signal neuromorphic processing systems.
