subject: gross and value added exports

description: One of the most important features in the international trade over the recent decades has been the increased fragmentation of the production process. This has been facilitated, in part, by the development and maturation of global value chains (GVCs).The improved availability of value-added trade data allows us to identify more clearly what fragment in the production chain is internationally competitive in a particular country. The paper examines global agri-food export performance in the light of these changes with special emphasis on the impacts of economic crisis using the concept of normalised revealed comparative advantage (NRCA) in terms of both gross exports and value-added for 61 countries over period 1995 and 2011. Systematically comparing these distributions reveals significant differences for NRCA based on gross exports versus valueadded data.

description: Information and, in particular, mobile technologies play an increasingly important role in the economic environment. The article surveys attitudes of Central European Czech customers to mobile phone usage for purchasing products and payments. Based on the results that were gained by the survey the paper suggests opportunities for further business development in the stated areas. The data was obtained by a combination of quantitative and qualitative research using a standardised questionnaire survey among respondents of all age groups. Data was collected throughout the year 2017. By random and targeted selection, 1335 respondents were selected for the survey. Based on the survey data analysis it was observed that Internet shopping via mobile phones has not been widespread up to now. Entrance tickets and fare tickets, electronics, clothing, and cosmetics are the most frequently purchased products via mobile phones. Despite an enormous potential of smartphones current users have not deployed their functions entirely so far.
MARKET PERFORMANCE IN THE UNITED STATES VEGETABLE OIL INDUSTRY: AN APPLICATION OF SIMULATION FOR MARKET ANALYSIS

description: The purpose of this paper is to discuss the use of simulation as a tool for market performance analysis. A specific application is made to the processing sector of the domestic vegetable oil industry, a highly concentrated sector for which price and cost data are not readily available. Using representative plant and firm models, returns on five products are estimated over time by simulating production and marketing functions at actual input and output prices by months for the period January 1974 through December 1975. The results indicate that market power in the vegetable oil industry was insufficient to generate excessively high returns over this period, and demonstrate the potential of the simulation approach for use in studies of market performance.

description: The rational map ansatz of Houghton et al \cite{HMS} is generalised by allowing the profile function, usually a function of $r$, to depend also on $z$ and $\bar{z}$. It is shown that, within this ansatz, the energies of the lowest $B=2,3,4$ field configurations of the SU(2) Skyrme model are closer to the corresponding values of the true solutions of the model than those obtained within the original rational map ansatz. In particular, we present plots of the profile functions which do exhibit their dependence on $ z$ and $\bar{z}$. The obvious generalisation of the ansatz to higher SU(N) models involving the introduction of more projectors is briefly mentioned.

description: Chernoff's bound binds a tail probability (ie. $Pr(X \ge a)$, where $a \ge EX$). Assuming that the distribution of $X$ is $Q$, the logarithm of the bound is known to be equal to the value of relative entropy (or minus Kullback-Leibler distance) for $I$-projection $\hat P$ of $Q$ on a set $\mathcal{H} \triangleq \{P: E_PX = a\}$. Here, Chernoff's bound is related to Maximum Likelihood on exponential form and consequently implications for the notion of complementarity are discussed. Moreover, a novel form of the bound is proposed, which expresses the value of the Chernoff's bound directly in terms of the $I$-projection (or generalized $I$-projection).

HOUSEHOLD CAPITAL/LABOR RATIOS IN FARM FAMILIES

Publisher: name: Unknown
Year: 1976
Subjects: Consumer/Household Economics

description: The major insights provided by the so-called "new home economics" are that household activities are productive in nature and that they involve the use of the traditional factors of production. The implications are far-ranging and continue to be unpacked 10 years after the formal treatments by Becker, Lancaster and Muth [1, 6, 10]. The particular implications pursued in this paper have to do with the behavior of capital/labor ratios within the households, not the farms, of farm families. In particular, how do household capital/labor ratios of farm families respond to changes: in the prices of family members' time, in family income, in family size, and in certain characteristics of the farm enterprise?

description: Phase 1 of the vacuum ultra-violet (VUV) free-electron laser (FEL) at the TESLA Test Facility (TTF) recently concluded operation. It successfully demonstrated the saturation of a SASE FEL in the in the wavelength range of 80-120 nm. We present a posteriori start-to-end numerical simulations of this FEL. These simulations are based on the programs Astra and elegant for the generation and transport of the electron distribution. An independent simulation of the intricate beam dynamics in the magnetic bunch compressor is performed with the program CSRtrack. The SASE FEL process is simulated with the code FAST. From our detailed simulations and the resulting phase space distribution at the undulator entrance, we found that the FEL was driven only by a small fraction (slice) of the electron bunch. This "lasing slice" is located in the head of the bunch, and has a peak current of approximately 3 kA. A strong energy chirp (due to the space charge field after compression) within this slice had a significant influence on the FEL operation. Our study shows that the radiation pulse duration is about 40 fs (FWHM) with a corresponding peak power of 1.5 GW. The simulated FEL properties are compared with various experimental data and found to be in excellent agreement.

description: This paper proposes four fundamental requirements for establishing PDEs (partial differential equations) modeling irreversible processes. We show that the PDEs derived via the CDF (conservation-dissipation formalism) meet all the requirements. In doing so, we find useful constraints on the freedoms of CDF and point out that a shortcoming of the formalism can be remedied with the help of the Maxwell iteration. It is proved that the iteration preserves the gradient structure and strong dissipativeness of the CDF-based PDEs. A refined formulation of the second law of thermodynamics is given to characterize the strong dissipativeness, while the gradient structure corresponds to nonlinear Onsager relations. Further advantages and limitations of CDF will also be presented.

Dissipative solution to the Ericksen-Leslie system equipped with the Oseen-Frank energy

description: We analyze the Ericksen-Leslie system equipped with the Oseen-Frank energy in three space dimensions. The new concept of dissipative solutions is introduced. Recently, the author introduced the concept of measure-valued solutions to the considered system and showed global existence as well as weak-strong uniqueness of these generalized solutions. In this paper, we show that the expectation of the measure valued solution is a dissipative solution. The concept of a dissipative solution itself relies on an inequality instead of an equality, but is described by functions instead of parametrized measures. These solutions exist globally and fulfill the weak-strong uniqueness property. Additionally, we generalize the relative energy inequality to solutions fulfilling different nonhomogeneous Dirichlet boundary conditions and incorporate the influence of a temporarily constant electromagnetic field. Relying on this generalized energy inequality, we investigate the long-time behavior and show that all solutions converge for the large time limit to a certain steady state.

description: In the last few years, deep learning has solved seemingly intractable problems, boosting the hope to find approximate solutions to problems that now are considered unsolvable. Earthquake prediction, the Grail of Seismology, is, in this context of continuous exciting discoveries, an obvious choice for deep learning exploration. We review the entire literature of artificial neural network (ANN) applications for earthquake prediction (77 articles, 1994-2019 period) and find two emerging trends: an increasing interest in this domain, and a complexification of ANN models over time, towards deep learning. Despite apparent positive results observed in this corpus, we demonstrate that simpler models seem to offer similar predictive powers, if not better ones. Due to the structured, tabulated nature of earthquake catalogues, and the limited number of features so far considered, simpler and more transparent machine learning models seem preferable at the present stage of research. Those baseline models follow first physical principles and are consistent with the known empirical laws of Statistical Seismology, which have minimal abilities to predict large earthquakes.

description: Signals consisting of a sequence of pulses show that inherent origin of the 1/f noise is a Brownian fluctuation of the average interevent time between subsequent pulses of the pulse sequence. In this paper we generalize the model of interevent time to reproduce a variety of self-affine time series exhibiting power spectral density S(f) scaling as a power of the frequency f. Furthermore, we analyze the relation between the power-law correlations and the origin of the power-law probability distribution of the signal intensity. We introduce a stochastic multiplicative model for the time intervals between point events and analyze the statistical properties of the signal analytically and numerically. Such model system exhibits power-law spectral density S(f)~1/f**beta for various values of beta, including beta=1/2, 1 and 3/2. Explicit expressions for the power spectra in the low frequency limit and for the distribution density of the interevent time are obtained. The counting statistics of the events is analyzed analytically and numerically, as well. The specific interest of our analysis is related with the financial markets, where long-range correlations of price fluctuations largely depend on the number of transactions. We analyze the spectral density and counting statistics of the number of transactions. The model reproduces spectral properties of the real markets and explains the mechanism of power-law distribution of trading activity. The study provides evidence that the statistical properties of the financial markets are enclosed in the statistics of the time interval between trades. A multiplicative point process serves as a consistent model generating this statistics.

description: In the framework of the Schwinger-Dyson equation and the Bethe-Salpeter equation in the improved ladder approximation, we calculate the pi^+ - pi^0 mass difference on the same footing as the pion decay constant and the QCD S parameter (or L_{10}) through the difference between the vector current correlator Π_{VV} and the axial-vector current correlator Π_{AA}. We find that all the results can be fit to the experimental values for rather large Lambda_{QCD} \sim 700 MeV which reflects the ``scale ambiguity''. By fitting to the calculated data using the pole saturated form of Π_{VV} - Π_{AA}, we also derive masses and decay constants of rho meson and a_1 meson, which we found are consistent with the experiments rather insensitively to the ``scale ambiguity''.

Our main result states that the length function |E_t(f)| is a bilateral Laplace transform of a certain positive measure. In particular, the function ln|E_t(f)| is convex on any interval free of critical points of ln|f|. As another application we deduce explicit formulas of the length function in some special cases.

 Polyphrix varians: Carrasco, 1972:328. Listed.
 Polyphrix varians: Yu & Horstmann, 1997:284. Listed.
The examined specimen from northern Brazil has most of the features described by Townes for the species, except for the following additions or differences. Antenna with 33–34 flagellomeres; pronotum with dorsal submarginal protuberance moderately small, sharp (Fig. 13), projecting laterally (Fig. 16); median portion of postpectal carina weak and very short; transverse furrow at base of propodeum laterally with three longitudinal, short wrinkles; propodeum behind anterior transverse carina with about 10 distinct, straight, regular, transverse wrinkles, anteriorly weaker than posteriorly (Fig. 19); areolet rectangular, 1.87–2.40 wider than high; ventral valve of ovipositor with 8 teeth, the last 3– 4 faint. The overall “fulvoferruginous” color described by Townes is here interpreted as dark orange (200,119,063) (Fig. 16), the first metasomal tergite basal 0.3 is yellowish, with dark orange in the middle, apical 0.3 brownish, with a white stripe on the apex; tergite 2 with apical 0.17 orange.
 Distribution. The specimens of P. varians originally studied by Townes, now at the American Entomological Institute, were checked, but none have been collected in Peru. Therefore, the occurrence of P. varians in that country, as registered by Townes (1970) and later cited by Carrasco (1972), is incorrect. The specimens examined by the authors were collected recently in the Amazon Basin, Brazil, at nearly the same latitude and about 4º W from the type locality.
 Material examined. Three females: Brazil, PA, Melgaço, Caxiuanã, Trilha Estação Científica Ferreira Pena, 13–16.XI.2003, yellow pans, APAguiar & JDias, and same data except Trilha Igarapé Tijucaquara, 18–21.XI.2003; Brasil, GO, Uruaçu, Serra da Mesa Survey, 14º17.0´S 48º54.8´W, 27.V.1996, yellow pans along permanent stream, N.F.Johnson leg.

description: Neural networks are increasingly used for graph classification in a variety of contexts. Social media is a critical application area in this space, however the characteristics of social media graphs differ from those seen in most popular benchmark datasets. Social networks tend to be large and sparse, while benchmarks are small and dense. Classically, large and sparse networks are analyzed by studying the distribution of local properties. Inspired by this, we introduce Graph-Hist: an end-to-end architecture that extracts a graph's latent local features, bins nodes together along 1-D cross sections of the feature space, and classifies the graph based on this multi-channel histogram. We show that Graph-Hist improves state of the art performance on true social media benchmark datasets, while still performing well on other benchmarks. Finally, we demonstrate Graph-Hist's performance by conducting bot detection in social media. While sophisticated bot and cyborg accounts increasingly evade traditional detection methods, they leave artificial artifacts in their conversational graph that are detected through graph classification. We apply Graph-Hist to classify these conversational graphs. In the process, we confirm that social media graphs are different than most baselines and that Graph-Hist outperforms existing bot-detection models.

description: Hedonic land price models often use parcel size as an explanatory variable. Empirical analyses, however, are rather ambiguous regarding the direction and the size of the effect of this variable on farmland values. The objective of this paper is to investigate this size-price relation in detail and to derive recommendations for an appropriate specification of hedonic land price models. Our analysis consists of three steps. First, we conduct a meta-analysis based on a comprehensive literature review. Second, we analyze a dataset of more than 80,000 land transactions in Saxony-Anhalt, Germany, using the non-parametric locally weighted scatterplot smoothing (LOWESS) estimator. This unconditional smoothing algorithm identifies negative size-price relations for very small and large plots, whereas it finds a positive relation for medium plot. We use this finding in our third step, a hedonic land price model, in which the size-price relation is modelled conditional on land and buyer characteristics. From these steps, we conclude that the complex relationship between land price and plot size cannot be captured by a simple functional form since it is affected by several economic factors, such as economies of size, transaction cost, and financial constraints.

description: The present study integrates multivariate distributions of risk posed by weather and price variation over time with the decision support tool GrassGro, defining financial risk profiles showing the probabilities of losses and gains for given management plans. A farm in Tarcutta, NSW, with 1000 ha of pasture and a merino ewe flock stocked at 5 ewes/ha, was simulated as producing crossbred lambs and 20-micron wool, with purchased replacement ewes. Ewe diets were supplemented with purchased wheat grain when pastures were inadequate. GrassGro simulations provided the production base upon which we could build whole-farm financial profiles including all other costs, calculated by application of the Monte Carlo facility in @RISK. The probability distribution of gross margins over the 2002-2017 period was negative 26% of the time, owing to the unusual number of drought years in that sequence. Assuming an opening debt of zero and an overdraft facility with a bank, the risk profile after 10 years indicates farm net profit after taxes (NPAT) or growth in equity was negative 48% of the time. The same farm, but with opening debts of $0.7m, shows NPAT would have been negative 55% of the time. The 10-year median changes in equity for the farm with opening debts of zero and $0.7m were +$0.09 million and -$1.1 million, respectively. The GrassGro model alone, assumes constant prices to calculate gross margins and offers no financial risk information. The methods described in this paper allow extending the usefulness of the industry-standard GrassGro by illuminating the likely financial risk profile with the farmer’s own management information.

Ang propetang Messenian, si Theokles, ay natuklasan sa kanyang kakila-kilabot ang isang ligaw na puno ng igos na tumubo sa ibabaw ng ilog Neda at ang mga dahon ay dumampi sa tubig, at napagtanto ang kahulugan nito. Ipinaalam ni Theokles kay Aristomenes na isapuso ito. Bagama't naniniwala siyang malapit na ang wakas, itinago ito ni Aristomenes at Theokles mula sa mga Messenians.
Ngayon, ayon sa alamat, mayroong isang pastol ng Laconian na umibig sa isang babaeng Messenian sa Eira. Sa tuwing nagbabantay ang kanyang asawa, pumupuslit ito sa bahay para makipag-sex sa kanya. Sa gabi ng isang kakila-kilabot na bagyo na may malakas na ulan, at habang si Aristomenes ay nakahiga sa isang sugat, ang mga bantay ay nagpasya na humingi ng kanlungan mula sa bagyo. Ang pastol, na napagtanto na si Eira ay pansamantalang walang pagtatanggol, siya ay tumakas at pumunta sa heneral ng Laconian na agad na naglunsad ng isang pag-atake at nakakuha ng pagpasok sa bayan. Matindi ang labanan. Ginawa ng mga Laconian ang diskarte ng pagsuray-suray sa mga tungkulin ng mga lalaki upang habang ang isang grupo ay natutulog, ang isa ay lumaban, at kabaliktaran. Nang mapagod ang mga Messenian, nagpasya si Aristomenes na pangunahan ang mga babae at bata palabas, at pinahintulutan iyon ng mga Laconian. Iyon ay kung paano nakilala ng mga Messenian ang wakas pagkatapos ng labing-isang taon ng patuloy na pakikidigma.
Ang bottomline ay ang mga Messenians ay natalo ng mga Spartan. Sa huli - ang orakulo at propesiya ay naging mahalagang bahagi ng kamalayang panlipunan. Ipinakita ng sikolohiya ng pagsasalaysay na ang mga salaysay ay mahalaga sa mga pananaw ng mga tao - at mga pananaw sa mundo. Kaya, ang hula sa sinaunang mundo ay may mahalagang papel sa pagtatalaga ng isang salaysay - isang kuwento na humubog din sa hinaharap pati na rin sa kasalukuyang pag-iisip.

description: The rapid urbanization and income growth have led to changes in the global food systems and nutrition transition in many developing countries. The prevalence of obesity and dietary-related diseases has become an urgent issue in developing national health policies. Taiwan is a rapidly aging society and its highest prevalence of obesity is observed in adults above 65 years old. This paper aims to find the optimal age- specific dietary intake pattern for both sexes based on the data from Nutrition and Health Surveys in Taiwan (NAHSIT). Goal programming approach is adopted to minimize the gap between observed diet and the dietary recommendation intakes (DRIs) from the public health authorities. Food consumption constraints is added to prevent diet plans from including unreasonable pattern and to minimize impacts on household food expenditures. Our result suggests that lack of calcium intake is a common problem for all age groups and both sexes in Taiwan and a shift from meat and oil products to more fish, nuts and vegetables is required. The age- and gender-specific results also show how goal programming modelling can be used to translate the DRIs into economically acceptable food plans.
Nonradiating normal modes in a classical many-body model of matter radiation interaction

description: We consider a classical model of matter--radiation interaction, in which the matter is represented by a system of infinitely many dipoles on a one--dimensional lattice, and the system is dealt with in the so--called dipole (i.e. linearized) approximation. We prove that there exist normal--mode solutions of the complete system, so that in particular the dipoles, though performing accelerated motions, do not radiate energy away. This comes about in virtue of an exact compensation which we prove to occur, for each dipole, between the ``radiation reaction force'' and a part of the retarded forces due to all the other dipoles. This fact corresponds to a certain identity which we name after Oseen, since it occurs that this researcher did actually propose it, already in the year 1916. We finally make a connection with a paper of Wheeler and Feynman on the foundations of electrodynamics. It turns out indeed that the Oseen identity, which we prove here in a particular model, is in fact a weak form of a general identity that such authors were assuming as an independent postulate.

How does off-farm work participation of farm couples affect household land transfer choices? An empirical investigation

description: Off-farm work plays a significant role in diversifying rural income and reducing risks generated from relying solely on agricultural production. Prior studies have examined the association between off-farm work participation and land use behaviors of rural households, but little attention has been paid to the effects of the joint off-farm work decisions of farm couples on land transfer choices. To bridge this gap, this study investigates the determinants of farm couples’ off-farm work participation, using a seemingly unrelated bivariate probit regression model and survey data collected from Hubei province of China. We also estimate the impact of the joint off-farm work decisions of farm couples on land transfer choices by employing a multinomial logit model and controlling for the endogeneity issues of off-farm work variables. The empirical results show that farm couples are jointly making decisions to work off the farm, but their decisions affect household land transfer choices differently. In particular, we show that the husbands participating in the off-farm work are more likely to rent in land, while their wives are less likely to do so. Both the husbands and wives are more likely to rent out land if they work off the farm. Our findings highlight the importance of farm couples’ off-farm work decisions in stimulating the development of rural land rental markets.

description: Previous studies indicate that nonlinear properties of Gaussian time series with long-range correlations, $u_i$, can be detected and quantified by studying the correlations in the magnitude series $|u_i|$, i.e., the ``volatility''. However, the origin for this empirical observation still remains unclear, and the exact relation between the correlations in $u_i$ and the correlations in $|u_i|$ is still unknown. Here we find analytical relations between the scaling exponent of linear series $u_i$ and its magnitude series $|u_i|$. Moreover, we find that nonlinear time series exhibit stronger (or the same) correlations in the magnitude time series compared to linear time series with the same two-point correlations. Based on these results we propose a simple model that generates multifractal time series by explicitly inserting long range correlations in the magnitude series; the nonlinear multifractal time series is generated by multiplying a long-range correlated time series (that represents the magnitude series) with uncorrelated time series [that represents the sign series $sgn(u_i)$]. Our results of magnitude series correlations may help to identify linear and nonlinear processes in experimental records.

description: Use of public natural resources for private gain is a longstanding, hotly contested politicaleconomic issue across the world. Publicly owned natural resources generate social benefits beyond private commodity uses and exploitation – recreational, environmental, ecological, biological, preservation and conservation, existence values, and aesthetics. The dynamics of natural resource use and exploitation leads to asymmetric information on the actions taken to exploit resource, the stock levels of resources, and net benefit flows to society. Imperfect and costly monitoring and enforcement in a continuous time setting lead to new questions, results, and insights. We model this as a countable sequence of dynamic sub-games. Each sub-game is played in continuous time for a random length of time between monitoring events with an infinite support. Each subgame has three players: a public natural resource administrator, the principle; a private commodity user, the agent; and nature, which serves to draw a random agent from a measure space of potential commodity uses at the beginning of each sub-game and to draw the random time between sequential monitoring events. These are not repeated games, even in a stationary long-run equilibrium distribution context. An interior solution is obtained for the optimal monitoring rate and penalty function in the event of noncompliance. Several new results are obtained that, on the surface, appear to be somewhat surprising, perhaps even contrary to standard results on regulation and externalities in commodity use. The results relate to, extend, and connect several strands of the existing literature – including efficiency wages, crime and punishment, environmental regulation, and dynamic games.

description: This paper is devoted to the analysis of available experimental data and preparation of predictive models for binding affinity of molecules with respect to two nuclear receptors involved in endocrine disruption (ED): the oestrogen (ER) and the androgen (AR) receptors. The ED-relevant data were retrieved from multiple sources, including the CERAPP, CoMPARA, and the Tox21 projects as well as ChEMBL and PubChem databases. Data analysis performed with the help of generative topographic mapping revealed the problem of low agreement between experimental values from different sources. Collected data were used to train both classification models for ER and AR binding activities and regression models for relative binding affinity (RBA) and median inhibition concentration (IC50). These models displayed relatively poor performance in classification (sensitivities ER = 0.34, AR = 0.49) and in regression (determination coefficient r2 for the RBA and IC50 models in external validation varied from 0.44 to 0.76). Our analysis demonstrates that low models’ performance resulted from misinterpreted experimental endpoints or wrongly reported values, thus confirming the observations reported in CERAPP and CoMPARA studies. Developed models and collected data sets included of 6215 (ER) and 3789 (AR) unique compounds, which are freely available.

description: Aggregation of ice crystals is a key process governing precipitation. Individual ice crystals exhibit considerable diversity of shape, and a wide range of physical processes could influence their aggregation; despite this we show that a simple computer model captures key features of aggregate shape and size distribution reported recently from Cirrus clouds. The results prompt a new way to plot the experimental size distributions leading to remarkably good dynamical scaling. That scaling independently confirms that there is a single dominant aggregation mechanism at play, albeit our model (based on undeflected trajectories to contact) does not capture its form exactly.

description: The discovery of new materials as well as the determination of a vast set of materials properties for science and technology is a fast growing field of research, with contributions from many groups worldwide. Materials data from individual research groups is traditionally disseminated by means of loosely interconnected, peer-reviewed publications. MatD3 is an open-source, dedicated database and web application framework designed to store, curate and disseminate experimental and theoretical materials data generated by individual research groups or research consortia. A research group can set up its own instance of MatD3 and publish scientific results or simply use an existing online MatD3 instance. Disseminating research data in this form enables broader access, reproducibility, and repurposing of scientific products. MatD3 is a general purpose database that does not focus on any specific level of theory or experimental method. Instead, the focus is on storing and making accessible the data and making it straightforward to curate them.
