description: This paper examines the effects of environmental zoning policies on lakefront land development, sorting, and economic welfare in a model where agents are heterogeneous in preferences and income. Agents consume lakefront amenities that are endogenous to development and the sorting process yields lakes which differ by amenities and frontage prices. Our findings include the following: i) lakes become more homogeneous with a collapsing price premium as incomes grow, ii) zoning can preserve the sorting process and be welfare improving, and iii) land prices may not capture all welfare effects from zoning.

description: High-fidelity modeling of blood flow is crucial for enhancing our understanding of cardiovascular disease. Despite significant advances in computational and experimental characterization of blood flow, the knowledge that we can acquire from such investigations remains limited by the presence of uncertainty in parameters, low spatiotemporal resolution, and measurement noise. Additionally, extracting useful information from these datasets is challenging. Data-driven modeling techniques have the potential to overcome these challenges and transform cardiovascular flow modeling. In this paper, we review several data-driven modeling techniques, highlight the common ideas and principles that emerge across numerous such techniques, and provide illustrative examples of how they could be used in the context of cardiovascular fluid mechanics. In particular, we discuss principal component analysis (PCA), robust PCA, compressed sensing, the Kalman filter for data assimilation, low-rank data recovery, and several additional methods for reduced-order modeling for cardiovascular flows, including the dynamic mode decomposition (DMD), and the sparse identification of nonlinear dynamics (SINDy). All of these techniques are presented in the context of cardiovascular flows with simple examples. These data-driven modeling techniques have the potential to transform computational and experimental cardiovascular flow research, and we discuss challenges and opportunities in applying these techniques in the field, looking ultimately towards data-driven patient-specific blood flow modeling.
Governance Structure, Perception, and Innovation in Credence Food Transactions: The Role of Food Community Networks

description: Promoting transactions of more sustainable-oriented foods can be (socially and privately) complex and costly. New institutional economics (NIE) explains these dynamics by analyzing the choice of the "most cost-economizing" governance structure to carry out a transaction where credence attributes are involved. The way different governance structures can influence the change of consumers and producers perceptions and preferences for credence foods is completely neglected. On the other hand behavioral economics underlines the role of status quo bias and framing in this type of decision making process. We use new institutional and behavioural economics arguments to conceptualize the emerging of a new governance structure in the domain of credence food transactions which we defined as food community network (FCN).

description: Lignocellulosic portion of municipal solid waste (MSW) is considered a potential feedstock for fuel ethanol production. I review the trends in MSW generation, composition and disposal practices, and evaluate the aggregate and regional potential of MSW as a feedstock. I present an overview of the current technology of MSW to ethanol conversion. An attractive feature of MSW-ethanol conversion is that the feedstock is available at a negative cost; i.e. disposal facilities charge tipping fees ranging from $15-$100/ton to accept MSW. I assess the financial feasibility of a typical MSW-ethanol plant with a capacity of 500 tons per day under a number of scenarios with respect to tipping fees, ethanol prices, capital costs, byproduct prices and ethanol tax incentives. I find the profitability to be robust across scenarios. I then discuss technical, economic, environmental and social barriers that inhibit commercialization.

description: This work provides the community with an easily executable open-source Python package designed to automize the evaluation of Interfacial Phonons (InterPhon). Its strategy of arbitrarily defining the interfacial region and periodicity alleviates the excessive computational cost in applying ab initio phonon calculations to interfaces and enables efficient extraction of interfacial phonons. InterPhon makes it possible to apply all of the phonon-based predictions that have been available for bulk systems, to interfacial systems. The first example, in which this package was applied to InAs surfaces, demonstrates a systematic structure search for unexplored surface reconstructions, navigated by the imaginary mode of surface phonons. It eventually explains the anisotropic surface vibrations of the polar crystal. The second example, involving oxygen adsorption on Cu, reveals adsorption-induced vibrational change and its contribution to energetic stability. The third example, on a Si/GaAs interface, shows distinct vibrational patterns depending on interfacial structures. It leads to a prediction regarding the structural transition of interfaces and unveils the processing conditions for spontaneous growth of GaAs nanowires on Si. High-level automation in InterPhon will be of great help in elucidating interfacial atomic dynamics and in implementing an automated computational workflow for diverse interfacial systems.

description: We report on the distribution of metallicities, [Fe/H], for very metal-poor stars in the halo of the Galaxy. Although the primary information on the nature of the Metallicity Distribution Function (MDF) is obtained from the two major recent surveys for metal-poor stars, the HK survey of Beers and collaborators, and the Hamburg/ESO Survey of Christlieb and collaborators, we also discuss the MDF derived from the publicly available database of stellar spectra and photometry contained in the third data release of the Sloan Digital Sky Survey (SDSS DR-3). Even though the SDSS was not originally planned as a stellar survey, significant numbers of stars have been observed to date -- DR-3 contains spectroscopy for over 70,000 stars, at least half of which are suitable for abundance determinations. There are as many very metal-poor ([Fe/H] < -2.0) stars in DR-3 as have been obtained from all previous survey efforts combined. We also discuss prospects for significant expansion of the list of metal-poor stars to be obtained from the recently funded extension of the SDSS, which includes the project SEGUE: Sloan Extension for Galactic Understanding and Exploration.

description: In this paper, results from a study on the use of improved coffee production technology schemes among smallholder coffee producers in three prominent coffee producing regions in Honduras are presented. The impact of various schemes (trajectories) in which different agents influence the producers’ decision to use new technologies was analyzed. In particular, there are differences in the influence of a) private coffee buying organizations and b) government and public development agencies on the innovation behavior of coffee growers. Drawing from network data that depict the internal and outbound connectedness of producers in three village communities in main coffee producing zones in Honduras, tools of social network analysis were applied to find out how interactions with certain agents, separately and cumulatively, has influenced their use of improved methods in coffee production and marketing. The results suggest that there are significant differences in the way that various providers of knowledge and technology, especially private buyers and development agencies, influence the farmers’ behavior towards innovation. The influence of buyers, according to the data, is focused on certification and quality aspects, whereas development agents focus on improved agronomic practices. Farmers who communicate with the extension branch of input providers tend to be more innovative. These results suggest that development programs should take more seriously into account the role of private actors in innovation among agricultural producers and, hence, design development programs in such a way to allow for collaboration with these agents.

The competition will be held in the fall of 2022. It will be concluded at the Northern Lights Deep Learning conference focusing on the segmentation of buildings using aerial images and laser data. We propose two different tasks to segment buildings, where the first task can only utilize aerial images, while the second must use laser data (LiDAR) with or without aerial images. Furthermore, we use IoU and Boundary IoU to properly evaluate the precision of the models, with the latter being an IoU measure that evaluates the results' boundaries. We provide the participants with a training dataset and keep a test dataset for evaluation.

description: As 2D materials such as graphene, transition metal dichalcogenides, and 2D polymers become more prevalent, solution processing and colloidal-state properties are being exploited to create advanced and functional materials. However, our understanding of the fundamental behavior of 2D sheets and membranes in fluid flow is still lacking. In this work, we perform numerical simulations of athermal semiflexible sheets with hydrodynamic interactions in shear flow. For sheets initially oriented in the flow-gradient plane, we find buckling instabilities of different mode numbers that vary with bending stiffness and can be understood with a quasi-static model of elasticity. For different initial orientations, chaotic tumbling trajectories are observed. Notably, we find that sheets fold or crumple before tumbling but do not stretch again upon applying greater shear.

REVIEW OF SOME OPERATIONAL PROCEDURES TO INCORPORATE EQUITY OBJECTIVES IN PROJECT APPRAISAL

Subjects: Research Methods/ Statistical Methods

description: In recent years there has been a growing interest in the development of methodologies related to the formulation and appraisal of projects. This is reflected in an increasing number of scientific papers and courses offered at different levels on the subject, most of which are directed for application in less developed countries. A wide variety of institutions are contributing in different ways to this development. Resulting from this interest, several operational procedures have been suggested which enable the analyst to perform financial as well as social appraisal of projects, where financial refers specifically to appraisal for the private and/or public participants in the project, and social refers to analysis from the perspective of economy-wide effects. The main objective of this paper is to review the most important operational procedures that have been suggested as a means to incorporate value judgements on income distribution in a systematic way into social cost benefit analysis. In fact, one of the main reasons that explain why methods to formally incorporate distribution concerns in project analysis are not a common practice, is a general lack of knowledge of those procedures which have been suggested and tried in case studies.
Willingness to Pay for Traceable Meat Attributes: A Meta-analysis
Creators: name: Cicia, Gianni
name: Colantuoni, Francesca
Publisher: name: CentMA
Year: 2010
Subjects: Meta-analysis; food traceability; willingness to Pay

description: Several researches evaluated consumers’ Willingness To Pay (WTP) for each meat traceable attribute, generating a great deal of information in this regard, although specific to the conditions of each study. In light of this, WTP estimates for traceability characteristics differ across the literature, leading sometimes to contrasting interpretations. Seeking a full, meaningful statistical description of the findings of a collection of studies, the meta-analysis allows us to analyze consistency across studies and control for factors thought to drive variations in WTP estimates. The meta-analysis has been conducted using 23 studies that, in aggregate, report 88 valuations for WTP. Our results, aside from releasing unconditional information on the WTP for single meat traceable attributes, show how certain study-specific characteristics, like the base price and the country where the study has been conducted, have a significant impact on WTP estimates.

description: This study is concerned with a quantitative examination of the Indonesian natural rubber. The main objective of the study is to analyze the nature of the supply of and demand for Indonesian natural rubber. To meet the above objective a simultaneous equation model was developed consisting of fifteen behavioral equations and six definitional identities which are hypothesized to describe the annual structure of the Indonesian natural rubber and its place in the world market for the period 1970 through 1990. The Micro-TSP computer software package was used to carry out the analysis in this study. The data used were primarily taken from several sources. The study found that production and export supply of Indonesian natural rubber, demand for rubber both in the U.S. and outside the U.S. markets, and foreign import demand for Indonesian natural rubber were perfectly price inelastic. Moreover, level of production -- which depends mainly on the extent of the mature tree area and yield -primarily determines for the export supply, and yield is influenced by the price of natural rubber in both the world and domestic market price. Furthermore, demand for natural rubber is influenced mainly by the automobile industry. The major policy implication of the above findings is that dependence on one commodity as a source of export earning is subject to risk. In other words, diversification of export crop promotion must be continued.

description: Never before has food been as safe and secure as it is today, but simultaneously, society has become increasingly critical towards agricultural and food related issues. This two-sided development between society and agribusiness will be analyzed using Framing Theory. A quantitative semantic analysis was applied to evaluate the web-based social media in Germany. 50,931 web posts were collected covering 21 issues identified as relevant for the agri-food sector. The results show that all contentious issues are mainly framed in a two-sided way. The modern productivity-driven industry is judged as a negative development, trends returning to a more natural food production are seen as positive.

description: В статье предложены геометрические модели физического состояния воды и водяного пара с дальнейшим аналитическим описанием при помощи математического аппарата геометрического моделирования процессов и явлений (БН-исчисление). Для моделирования данного процесса исходные значения физического состояния воды и водяного пара были взяты с i-d диаграммы влажного воздуха. Геометрическое моделирование представлено в виде двух отдельных составных поверхностей отклика для влагосодержания и энтальпии влажного воздуха и является двухпараметрическим множеством, которое принадлежит трехмерному пространству. В свою очередь каждая поверхность отклика была разбита на три отсека с определенными границами и аналитически описана с помощью точечных уравнений дуг кривых, проходящих через наперед заданные точки, что позволило максимально точно рассчитать искомые значения параметров в программном комплексе Maple. Приведен анализ эффективности геометрического моделирования значений влагосодержания и энтальпии влажного воздуха, которые представлены графически на основе i-d диаграммы, и расчетных значений, полученных на основе разработанных геометрических моделей. Предложенные геометрические модели позволяют не только определить все необходимые значения параметров физического состояния воды и водяного пара, что позволяет автоматизировать процесс проектирования, но и оптимизировать их с помощью методов математического анализа.
description: The article proposes the geometric models of water and water vapor physical state with a further analytical description using the mathematical apparatus of geometric modeling of processes and phenomena (BN-calculation). The initial values of water and water vapor physical state are taken from the i-d diagram of humid air to simulate this process. Geometric modeling is presented as two different response surfaces for moisture content and enthalpy of humid air. Geometric models are a two-parameter set that belongs to three-dimensional space. Each response surface was divided into three compartments with defined boundaries and analytically described using point equations for arcs of curves passing through preassigned points. This allowed accurately calculating the desired values of the parameters in the software package Maple. The analysis of the effectiveness of geometric modeling of moisture content and enthalpy of humid air is given. The effectiveness is presented graphically based on i-d diagrams, and calculated values obtained based on the developed geometric models. The proposed geometric models allow determining all the necessary values of parameters of water and water vapor physical state. This allows automating the design process, as well as optimizing the simulation using mathematical analysis methods.

Subjects: Land Economics/Use

description: The farm real estate market is different from commodity markets because land has unique characteristics such as durability and immobility. Moreover, the heterogeneity of land and relatively low activity of land transactions limits the availability of pricing information for specific properties. Because land is the primary asset and the least liquid of any farm company, its valuation plays an important role in financial analysis. The purpose of this paper is to compare different approaches to estimate the value of land. These methods include: sales comparison, price trend, capitalization and modified capitalization. Using these four methods, different estimates will be obtained to assess the financial situation of Las Estancias S.A., an Argentine farm corporation. The impact of different land valuation approaches upon the financial decision making process will also be analyzed. This research studies the different land valuation methods and their effects on the financial decision making process. The information gathered from this study will allow the analyst to determine if the company is really too highly leveraged. In addition, the values arrived at for the individual farms will be used to determine which, if any, assets should be liquidated.

description: A meteor outburst consisting of at least 22 meteors above the Baltic sea and southern Scandinavia that occurred on 30 October 2022 was recorded using multiple cameras. A bright fireball was followed by fainter meteors over a 10 second period. All the meteors were travelling on parallel trajectories. The goal of this study is to determine the atmospheric trajectories and photometric masses of meteors and to use these data to determine the specifics of the progenitor meteoroid break-up and cluster formation. Double and triple-station observations using video cameras were used for the calculation of the atmospheric trajectories and photometric masses of the meteors. Their relative positions and mass distribution were then used to determine the time and cause of the meteoroid fragmentation. The relative position of the cluster particles in the atmosphere and the distribution of their masses best correspond to the separation of the smaller fragments from the mass-dominant fragment 10.6$\pm$1.7 days before the collision with Earth, assuming a meteoroid bulk density of 1000 kg.m$^{-3}$. The ejection velocities are in the range 0.16-0.61 m.s$^{-1}$. The directions of the ejection velocities are bounded by a cone with an apex angle of $43^\circ$. The axis of this cone has ecliptic coordinates of $l=154^\circ$ and $b=26^\circ$ and is $66^\circ$ away from the direction to the Sun. Thermal stresses appear to be the most likely cause of such meteor cluster formation.

description: Keywords in scientific articles have found their significance in information filtering and classification. In this article, we empirically investigated statistical characteristics and evolutionary properties of keywords in a very famous journal, namely Proceedings of the National Academy of Science of the United States of America (PNAS), including frequency distribution, temporal scaling behavior, and decay factor. The empirical results indicate that the keyword frequency in PNAS approximately follows a Zipf's law with exponent 0.86. In addition, there is a power-low correlation between the cumulative number of distinct keywords and the cumulative number of keyword occurrences. Extensive empirical analysis on some other journals' data is also presented, with decaying trends of most popular keywords being monitored. Interestingly, top journals from various subjects share very similar decaying tendency, while the journals of low impact factors exhibit completely different behavior. Those empirical characters may shed some light on the in-depth understanding of semantic evolutionary behaviors. In addition, the analysis of keyword-based system is helpful for the design of corresponding recommender systems.

description: TiFe intermetallic compound has been extensively studied, owing to its low cost, good volumetric hydrogen density, and easy tailoring of hydrogenation thermodynamics by elemental substitution. All these positive aspects make this material promising for large-scale applications of solid-state hydrogen storage. On the other hand, activation and kinetic issues should be amended and the role of elemental substitution should be further understood. This work investigates the thermodynamic changes induced by the variation of Ti content along the homogeneity range of the TiFe phase (Ti:Fe ratio from 1:1 to 1:0.9) and of the substitution of Mn for Fe between 0 and 5 at.%. In all considered alloys, the major phase is TiFe-type together with minor amounts of TiFe2 or \b{eta}-Ti-type and Ti4Fe2O-type at the Ti-poor and rich side of the TiFe phase domain, respectively. Thermodynamic data agree with the available literature but offer here a comprehensive picture of hydrogenation properties over an extended Ti and Mn compositional range. Moreover, it is demonstrated that Ti-rich alloys display enhanced storage capacities, as long as a limited amount of \b{eta}-Ti is formed. Both Mn and Ti substitutions increase the cell parameter by possibly substituting Fe, lowering the plateau pressures and decreasing the hysteresis of the isotherms. A full picture of the dependence of hydrogen storage properties as a function of the composition will be discussed, together with some observed correlations.

In the last 2-3 decades, technology served as a key policy instrument used by developed countries to aid the less developed ones. However, such a policy had led to the neglect of certain farming groups, particularly small farmers. Recent trends in agriculture development tend to pay special attention to the needs of small farmers. It is the small farmers who form the backbone of agriculture in many LDC's. As their development receives priority, so does the need to gain a better understanding of their farming needs. Small farmer response to technology has been unevenly distributed. This has not only varied amongst the LDC's, but technology adoption rates differ within countries. Besides many socio-economic constraints experts consider risk and uncertainty to play a dominant role in technology adoption. The major issue is to what extent should risk and uncertainty be taken into account while evaluating potential technology. Farmers in many developing countries have shown preference for traditional technology over the improved one. The discussion of this paper focuses on the decision making strategies of farmers. Particularly those strategies adopted in choice of varieties and allocation of resources to agriculture. The interest here is to see to what extent does risk and uncertainty enter the farmers decision process. The focus here is not limited to the small farmers alone, however, they are of special interest in this paper. Usually a small farmer is taken to be synonymous with a poor farmer, but farm size alone is an inadequate criteria for distinguishing a poor farmer from those that are better off. Net per capita income appears to be a better proxy by which to define small farmers. This paper will deal with the decision making aspects of small farmers. Particular emphasis is on the choice of technology, (with emphasis on varieties) under conditions of risk. The interest is in gaining insight into variables which affect farmer decision making.

description: Due to their ease of use and high accuracy, Word2Vec (W2V) word embeddings enjoy great success in the semantic representation of words, sentences, and whole documents as well as for semantic similarity estimation. However, they have the shortcoming that they are directly extracted from a surface representation, which does not adequately represent human thought processes and also performs poorly for highly ambiguous words. Therefore, we propose Semantic Concept Embeddings (CE) based on the MultiNet Semantic Network (SN) formalism, which addresses both shortcomings. The evaluation on a marketing target group distribution task showed that the accuracy of predicted target groups can be increased by combining traditional word embeddings with semantic CEs.

description: We present coincident observations of the Cosmic Microwave Background (CMB) from the Very Small Array (VSA) and Cosmic Background Imager (CBI) telescopes. The consistency of the full datasets is tested in the map plane and the Fourier plane, prior to the usual compression of CMB data into flat bandpowers. Of the three mosaics observed by each group, two are found to be in excellent agreement. In the third mosaic, there is a 2 sigma discrepancy between the correlation of the data and the level expected from Monte Carlo simulations. This is shown to be consistent with increased phase calibration errors on VSA data during summer observations. We also consider the parameter estimation method of each group. The key difference is the use of the variance window function in place of the bandpower window function, an approximation used by the VSA group. A re-evaluation of the VSA parameter estimates, using bandpower windows, shows that the two methods yield consistent results.

Pion gravitational form factors in a relativistic theory of composite particles

description: We extend our relativistic theory of electroweak properties of composite systems to describe simultaneously the gravitational form factors of hadrons. The approach is based on a version of the instant-form relativistic quantum mechanics and makes use of the modified impulse approximation. We exploit the general method of the relativistic invariant parametrizaton of local operators to write the energy-momentum tensor of a particle with an arbitrary spin. We use the obtained results to calculate the gravitational form factors of the pion assuming point-like constituent quarks. All but one parameters of our first-principle model were fixed previously in works on electromagnetic form factors. The only free parameter, $D_{q}$, is a characteristic of the gravitational form factor of a constituent quark. The derived form factors of the pion satisfy the constraints given by the general principles of the quantum field theory of hadron structure. The calculated gravitational form factors and gravitational mean-square radius are in a reasonable agreement with known results.

Year: 2009

description: In a general sense, this thesis examines several aspects of the Shijing [Chinese characters] (The Book of Odes) manuscript excavated at Fuyang [Chinese characters], Anhui province, the People's Republic of China. The introductory chapter provides background on the Fuyang Shi jing, as well as the transmitted versions of this Chinese classic. Further, it outlines the traditional scholarship dealing with the Shi jing and offers a detailed summary of the other chapters. Chapter one introduces the methodology used in chapters two and three of this thesis. Part one of this chapter demonstrates the manner in which lexical and graphic variation is defined and analyzed, while part two shows how graphs may be analyzed based on a clear understanding of orthographic feature. Chapter one also provides background on the history of early Chinese writing forms and the evolution of Chinese script. Chapter two is primarily an orthographic study with two main objectives: (A) to distinguish the physical nature of the Fuyang Shi jing; and (B) to date this manuscript. In the introduction to this chapter, I will also compare the Fuyang Shi jing with other early bamboo and silk manuscripts. Chapter three deals with lexical variation involving the Fuyang Shi jing and the various transmitted Shi jing texts. It has three objectives: (A) to provide new readings of several odes in the Shi jing; (B) to survey different types of lexical variation associated with the Fuyang manuscript; and (C) in each case determine which lexical variant, among the various possibilities, most likely represents the proximate original of the Shi jing.

description: Tanzania, like many developing countries has its share of problems associated with developing its rural sector where the majority of its population lives. Since independence, the government of Tanzania has proclaimed the development of the rural sector the cornerstone of the country's development strategy. A number of approaches have been tried in Tanzania. Some of them abolished and then re-established in an effort to pave a smooth road towards rural development through improved agricultural performance and provision of essential social services. Besides the provision of social services such as clean water, schools and dispensaries to about half of the rural population by 1982, none of the approaches has led to the anticipated transformation of production structures and productivity of the rural sector. Thus, an analysis of the approaches taken will attempt to identify those areas which need strengthening or further study to improve the performance of the rural sector. The principle aim of this paper is to provide some insights into the rural development policies and operations put into practice by the government of Tanzania since independence and discuss their success and/or failures. The specific objectives of this study are the following: (1) to identify the major constraints to rural development; (2) to identify and describe rural development policies implemented in Tanzania and evaluate their impact on agricultural development, farmers' participation in communal production activities, and the availability of social services to rural people; and (3) to draw some lessons from Tanzania's experience in rural development which may be useful for future policy action in Tanzania, as well as for rural development in Africa.

description: The objective of this study is to investigate the appropriateness of hand-held programmable calculators as a research tool for economists working on price policy issues in LDC's. The emphasis is on the use of programmable not for purposes of sophisticated analysis of large data sets, but rather for preliminary analysis of the sorts of data economists typically work with in the field. A few authors have attempted to develop and test research-oriented programs relating to particular fields of inquiry, but such efforts are not yet widespread. This study attempts to expand the scope of these preliminary efforts by exploring the possibility that programmable calculators might be adopted for use by the research economist working on price analysis issues. If hand-held calculators can be programmed to facilitate data transformation and to perform some of the functions normally performed by larger, slower and more costly computers, they will represent a valuable addition to the price analyst's tool kit. The procedure followed by the researcher was to write several data analysis programs and to test them on actual data samples in order to 1) develop useful software, and 2) weigh the advantages and disadvantages of working with the programmable calculator and thereby form conclusions about its potential usefulness as a field research tool.
