description: Research background: Rice (Oriza sativa) is a staple food in most homes in Nigeria, its demand has not been able to cope favourably well with the production. Efforts to develop and improve the production of the crop in the country were seriously curtailed due to inefficiency in the use of available resources. Purpose of the article: The study set to determine the effects of farmers’ entrepreneurial competencies (ECs) on technical efficiency (TE) of rice farms in South-west, Nigeria. Also, the study was trying to profile the socioeconomic characteristics of rice farmers and identifying their ECs in order to describe the determinants of technical efficiency of rice farms. Methods: A multistage sampling technique was employed to select 504 respondents from which information on their socioeconomic characteristics, their ECS’ variables and input-output variables were collected. The information gathered were analysed using descriptive statistics and stochastic frontier production (SFP) function (Cobb-Douglas model). Findings & value added: The results showed that farms were technically inefficient with a mean TE score of 0.6842 with evidence of increasing returns to scale. The results of the Maximum-likelihood Estimation of the SFP model reveals that the quantity of seed planted, farm size and amount of man-day labour used significantly explained the technical efficiency of rice farms. Also, some socioeconomic factors and ECs factors such as organising and commitment were found to be responsible for rice farmers’ inefficiency. The study recommends appropriate entrepreneurial training for rice farmers focussing on resource management and training the extension workers on necessary competency knowledge.

description: We present new calibrations of stellar parameters of O stars at solar metallicity taking non-LTE, wind, and line-blanketing effects into account. Gravities and absolute visual magnitudes are derived from results of recent spectroscopic analyses. Two types of effective temperature scales are derived: one from a compilation based on recent spectroscopic studies of a sample of massive stars - the ``observational scale'' - and the other from direct interpolations on a grid of non-LTE spherically extended line-blanketed models computed with the code CMFGEN (Hillier & Miller 1998) - the ``theoretical scale''. These Teff scales are then further used together with the grid of models to calibrate other parameters (bolometric correction, luminosity, radius, spectroscopic mass and ionising fluxes) as a function of spectral type and luminosity class. Compared to the earlier calibrations of Vacca et al. (1996) the main results are: 1) the effective temperature scales are cooler by 2000 to 8000 K, the reduction being the largest for early supergiants; 2) bolometric corrections are lower by 0.1 mag for a given temperature, and are lower by 0.3 - 0.6 mag for a given spectral type; 3) luminosities are reduced by 0.20 to 0.35 dex; 4) Lyman ionising fluxes are lower by 0.20 to 0.80 dex. We provide calibration tables for each luminosity class and for both types of Teff scales.

description: The pair correlation function of charge stabilized colloidal particles under strongly sheared conditions is studied using the analytical intermediate asymptotics method recently developed in [L. Banetta and A. Zaccone, Phys. Rev. E 99, 052606 (2019)] to solve the steady-state Smoluchowski equation for medium to high values of the Péclet number; the analytical theory works for dilute conditions. A rich physical behaviour is unveiled for the pair correlation function of colloids interacting via the repulsive Yukawa (or Debye-Hückel) potential, in both the extensional and compressional sectors of the solid angle. In the compression sector, a peak near contact is due to the advecting action of the flow and decreases upon increasing the coupling strength parameter $Γ$ of the Yukawa potential. Upon increasing the screening (Debye) length $κ^{-1}$, a secondary peak shows up, at a larger separation distance, slightly less than the Debye length. While this secondary peak grows, the primary peak near contact decreases. The secondary peak is attributed to the competition between the advecting (attractive-like) action of the flow in the compressions sector, and the repulsion due to the electrostatics. In the extensional sectors, a depletion layer (where the pair-correlation function is identically zero) near contact is predicted, the width of which increases upon increasing either $Γ$ or $κ^{-1}$.

description: Research background: The food system is central to a wide range of outcomes such as food security, nutrition and economic development. In this wise, the food systems must meet the needs of a growing and increasingly urbanized population. However, food system in developing countries is undergoing a rapid transformation towards high value products and food safety. Yet, the consumer demand drive towards the transformation has received much less attention. Hence, improvement in the agricultural and food systems must be viewed in the context of household food consumption patterns. Purpose of the article: This paper examined household food demand and food choice preferences among urban households in southwest, Nigeria. Understanding Nigeria’s Agrofood structure through urban eating pattern will proffer knowledge required for better policy design and implementation. Methods: The paper applies a quadratic almost ideal demand system (QUAIDS) model to a cross-sectional household survey data from two urban areas, and estimate price and expenditure elasticities as indicators of household sensitivity to market shocks. Findings & Value added: Analysis of frequency distribution on urban household’s preferences shows that convenience, availability, safety were important attributes influencing decisions to purchase foods. Demand estimations show positive expenditure elasticities for food groups with values close to unity. The animal-source foods and cereals were more expenditure-elastic in high urban areas (HUA) and low urban areas (LUA), respectively. All own-price elasticities are negative and LUA are more price-sensitive to most food groups compared to HUA. The price and expenditure results suggest that transformation of agro food products will come in place if convenience and food safety attributes are incorporated in food value chain.

We find that for existence there are no conditions on the degree of the nonlinearity provided the potential is positive. We furthermore prove that nonlinear noncommutative waves have infinite propagation speed, i.e., if the initial conditions at time 0 have a compact support then for any positive time the support of the solution can be arbitrarily large.

description: Research background: The intention of consumers to purchase branded goods and services is a building block for purchasing behaviour in agribusiness especially for fresh leafy vegetables with nutritional and health benefits in Africa. Purpose of the article: To examine the determinants of consumers’ intention to purchase fresh leafy vegetables, and to identify the constraints militating against shopping outlet decisions of fresh leafy vegetables by the rural and urban households in the Federal Capital Territory, Nigeria. Methods: The sampling techniques were employed to collect data from primary source were stratified, purposive and convenience to select 746 respondents (396 of urban and 350 of rural households). But 608 respondents (294 for Urban area and 314 for rural area, which represents 74.2% and 89.7%, respectively) were later used for the analysis. Convenience sampling was used at a point because there is no reliable sampling frame that was existing for the respective places. Findings & Value: This study reveals that are household size, farming as a primary occupation and distance of the consumers’ residence to the point of purchase leafy vegetables among both rural and urban households, with the exception of personal income which only influenced the purchasing intention of urban consumers. Poor storage facilities for fresh leafy vegetables was a major constraint to both rural and urban households in the choice of shopping outlets for fresh leafy vegetables in the Federal Capital Territory, Nigeria. All-inclusive policies should be enacted that has the potential to enhance the storage facilities for fresh leafy vegetables. For branded leafy vegetables to be purchased the shopping outlets must be made closer to the residence of the consumers.

description: Excerpts from the article: Commercial bank support of local government bond issues is of prime importance in helping rural communities foster economic growth and development. Rural banks' growing support of the municipal bond market Facilitated rural development efforts during the 1970's. However, there is a limit to the extent that rural banks can support rural municipal bonds. For rapidly growing areas, State or Federal programs aimed at improving the marketability of rural issues may improve the chances of sustained economic growth.

description: Excerpts from the article: During the 1970's, the rural areas of the United States experienced more rapid growth in population, income, and employment than did urban areas. From a rural viewpoint, this was a pleasant change from the experience of earlier years. Research by USDA rural development economists has looked at factors affecting growth—factors that need to be understood whether the aim of local leaders is to limit a boom or to encourage development. The factors are: increasing the availability of resources, expanding markets for local products, advancing technology, conquering geographic space, and building institutions. Action by local leaders can influence each factor.

description: We present an analytical method to estimate the condensate fraction $n_0/n$ in strongly correlated systems for which the zero-temperature static structure factor $S({\bf p})$ is known. The advantage of the proposed method is that it allows one to predict the long-range behavior of the one-body density matrix (i) in macroscopic and mesoscopic systems, (ii) in three- and two-dimensional geometry, (iii) at zero and low finite temperature, and (iv) in weakly and strongly correlated regimes. Our method is tested against exact values obtained with various quantum Monte Carlo methods in a number of strongly correlated systems showing an excellent agreement. The proposed technique is also useful in numerical simulations as it allows one to extrapolate the condensate fraction to the thermodynamic limit for particle numbers as small as tens to hundreds. Our method is especially valuable for extracting the condensate fraction from the experimentally measured static structure factor $S({\bf p})$, thus providing a new simple alternative technique for the estimation of $n_0/n$. We analyze available experimental data for $S({\bf p})$ of superfluid helium and find an excellent agreement with the experimental value of $n_0/n$.

description: Die Digitalisierung ist allgegenwärtig und prägt zunehmend alle Lebensbereiche. Auch Sozialdienste
können sich ihr nicht entziehen. Diese Master-Thesis widmet sich der Frage, was die Digitalisierung für
Sozialdienste bedeutet und untersucht die damit verbundenen Voraussetzungen, Auswirkungen,
Chancen sowie Risiken. Im Rahmen einer qualitativen Forschung wurden dazu leitfadengestützte Expert*
inneninterviews mit sechs Sozialdienstleitenden aus der Deutschschweiz durchgeführt und mittels
der inhaltlich strukturierenden qualitativen Inhaltsanalyse nach Kuckartz und Rädiker ausgewertet.
Die Ergebnisse verdeutlichen, dass ein gemeinsames Begriffsverständnis, das Bewusstsein für die
Notwendigkeit und die Kenntnis des Digitalisierungsstands grundlegend sind. Eine erfolgreiche Digitalisierung
erfordert zudem eine Strategie, welche auf die Bedürfnisse der Klientel sowie Mitarbeitenden
ausgerichtet ist und fortlaufend überprüft wird. Es ist eine Führung gefragt, welche die Digitalisierung
aktiv gestaltet und eine förderliche Organisationskultur etabliert. Ebenso gilt es die digitale Kompetenz
der Mitarbeitenden sowie der Klientel zu fördern. Prozessautomatisierungen entlasten von administrativen
Tätigkeiten, was eine effizientere und effektivere Fallführung ermöglicht. Darüber hinaus hat
die Digitalisierung das Potenzial, die Dienstleistungsqualität zu verbessern, indem sie niederschwellige,
orts- und zeitunabhängige Zugangs-, Informations- sowie Kommunikationsmöglichkeiten schafft. Insgesamt
zeigt sich, dass die Digitalisierung nicht nur die Nutzung digitaler Technologien, sondern eine
umfassende Transformation bedeutet, welche alle Ebenen der Organisation erfasst.

description: The paper analyzes the deforestation problem and its Sustainable Local Development (SLD) impact, during 1998-2005 periods. A stochastic frontier production function is defined for panel data of farm-specific variables. The inefficiency effects are assumed to be independently distributed as truncations of normal distributions with constant variance, but with means which are a linear function of observable variables. Panel Data was chosen between social and environment variable of the data base of EMNV’98-05. The results proof that the deforestation problem is explicated by household social expenditure and the poverty. The mean technical efficiency was 25 %, and the poverty reach significant level for explaining technical inefficiency on the stochastic frontier model. The technical efficiency by year was 33 %, 36 % y 5.6 during 1998, 2001 y 2005 respectively. With these considerations, I suggest an educational and specialization process lying on the environment policy for reducing the farmer’s problem effects.

description: The nuclear $p_\perp$-broadening of Drell-Yan and quarkonium ($J/ψ$, $Υ$) production in $π$A and pA collisions is investigated. The world data follow a simple scaling from SPS to LHC energies, once the process-dependent color factors are properly taken into account, which allows for the extraction of the transport coefficient in cold nuclear matter. We find that $\hat{q}(x)\propto x^{-α}$ with $α=0.25$-$0.30$. The magnitude of the transport coefficient at $x=10^{-2}$ is $\hat{q}_0=0.051$ GeV$^2$/fm and $\hat{q}_0=0.075$ GeV$^2$/fm, whether $Q\bar{Q}$ pairs are assumed to be produced as color octet or color singlet states, respectively. The relation between nuclear broadening data and the (CT14) gluon density is also investigated.

description: Under the condition of significant changes in the framework of EU Agricultural Policy Agro-Environmental Programmes are evaluated in this paper. The MEKA-Programme of Baden-Württemberg and the KULAP-Programme of Brandenburg, both measures under the EU-Regulation VO (EWG) 2078/92 of 1992, are analysed using farm level Linear Programming models. One of the most important results is that both, the MEKA- and the KULAP-Program, have positive environmental effects. In addition they are also responsible for significant transfer payments which under unfavourable production conditions can reach up to 40 % of the farm level gross margins. Farm structure, indicated by production conditions, crops and major production areas, is responsible for the application to the above mentioned programmes as well as for the extent of positive environmental effects. Losses in production efficiency and additional income effects are the consequence of non-consideration of the programmes offered. With respect to the results of the model calculation it is suggested that agro-environmental measures become more goal oriented and consider as far as possible regional conditions. More general programmes should become a more flexible and allow for flexible and dynamic reactions to changing circumstances.
Space-Time in Quantum Theory

Year: 2020
Subjects: subject: History and Philosophy of Physics (physics.hist-ph)
subject: FOS: Physical sciences

description: Quantum Theory, similar to Relativity Theory, requires a new concept of space-time, imposed by a universal constant. While velocity of light $c$ not being infinite calls for a redefinition of space-time on large and cosmological scales, quantization of action in terms of a finite, i.e. non vanishing, universal constant $h$ requires a redefinition of space-time on very small scales. Most importantly, the classical notion of "time", as one common continuous time variable and nature evolving continuously "in time", has to be replaced by an infinite manifold of transition rates for discontinuous quantum transitions. The fundamental laws of quantum physics, commutation relations and quantum equations of motion, resulted from Max Born's recognition of the basic principle of quantum physics: {\bf To each change in nature corresponds an integer number of quanta of action}. Action variables may only change by integer values of $h$, requiring all other physical quantities to change by discrete steps, "quantum jumps". The mathematical implementation of this principle led to commutation relations and quantum equations of motion. The notion of "point" in space-time looses its physical significance; quantum uncertainties of time, position, just as any other physical quantity, are necessary consequences of quantization of action.

description: We study nonlinear hyperbolic conservation laws with non-convex flux in one space dimension and, for a broad class of numerical methods based on summation by parts operators, we compute numerically the kinetic functions associated with each scheme. As established by LeFloch and collaborators, kinetic functions (for continuous or discrete models) uniquely characterize the macro-scale dynamics of small-scale dependent, undercompressive, nonclassical shock waves. We show here that various entropy-dissipative numerical schemes can yield nonclassical solutions containing classical shocks, including Fourier methods with (super-) spectral viscosity, finite difference schemes with artificial dissipation, discontinuous Galerkin schemes with or without modal filtering, and TeCNO schemes. We demonstrate numerically that entropy stability does not imply uniqueness of the limiting numerical solutions for scalar conservation laws in one space dimension, and we compute the associated kinetic functions in order to distinguish between these schemes. In addition, we design entropy-dissipative schemes for the Keyfitz-Kranzer system whose solutions are measures with delta shocks. This system illustrates the fact that entropy stability does not imply boundedness under grid refinement.

description: Quantum state transformations that are robust to experimental imperfections are important for applications in quantum information science and quantum sensing. Counterdiabatic (CD) approaches, which use knowledge of the underlying system Hamiltonian to actively correct for diabatic effects, are powerful tools for achieving simultaneously fast and stable state transformations. Protocols for CD driving have thus far been limited in their experimental implementation to discrete systems with just two or three levels, as well as bulk systems with scaling symmetries. Here, we extend the tool of CD control to a discrete synthetic lattice system composed of as many as nine sites. Although this system has a vanishing gap and thus no adiabatic support in the thermodynamic limit, we show that CD approaches can still give a substantial, several order-of-magnitude, improvement in fidelity over naive, fast adiabatic protocols.

description: We consider that there is no present and there is no future without the past, namely, without history, without knowing the past. Talking about history is both easy and difficult at the same time because history provokes an emotional reaction, a sentimental reaction, especially when it comes to local or national history. A nation that doesn't know its history is like a child that doesn't know his parents. We must focus on the present to build a future, but a future cannot be built if we do not know our past. The past or history is the accumulation of human experiences.
The Riemann Zeta Function and Vacuum Spectrum

description: A variant for the Hilbert and Polya spectral interpretation of the Riemann zeta function is proposed. Instead of looking for a self-adjoint linear operator H, whose spectrum coincides with the Riemann zeta zeros, we look for the complex poles of the S matrix that are mapped into the critical line in coincidence with the nontrivial Riemann zeroes. The associated quantum system, an infinity of "virtual resonances" described by the corresponding S matrix poles, can be interpreted as the quantum vacuum. The distribution of energy levels differences associated to these resonances shows the same characteristic features of random matrix theory.

description: Complete and consistent, i.e. theoretically appropriate demand systems have seldom been developed for Germany. Econometric food demand analyses have concentrated on single products and product groups. Generally, demand functions have been estimated using single equation methods. The purpose of this paper is to analyse the food demand in former West Germany on the basis of the Almost Ideal Demand System (AIDS) developed by DEATON and MUELLBAUER (1980). A two-stage demand system is based on data for the household type III gathered on a monthly basis during the period from 1966 to 1997. At a first stage, five aggregates of food (meats and fish; dairy and eggs; edible fats; cereals, fruits and vegetables; and other foods) and one non-food group are specified. The second stage includes four groups of meat (beef, pork, poultry, and other processed meats) and fish. The results of the demand system allow statements about the changes in food demand over time periods.

description: With commodity prices continuing to decrease and with policy constraint that farmers cannot easily increase their incomes by increasing volumes of production, they must find alternative ways to maintain their standard of living. This can be achieved by either niche marketing of agricultural products or by environmental payments, which are paid by either the government or the consumer. The results of a consumer survey carried out in Less Favoured Areas in Scotland, Germany, Greece, France and Italy to assess consumer attitudes of what constitutes the quality of lamb and the extent to which this provides an opportunity to exploit niche marketing, are discussed. Consumers generally have much less interest in the use of regional labelling, ecologically friendly production systems or the linkage of landscape and production systems in the buying decision. It is concluded that potential exists to develop niche markets for lamb and that these niches demonstrate significant regional differences. Equally, however, it is concluded that there are only limited rewards for production systems which are sympathetic to the environment. To achieve this goal, policy intervention is required, geared directly to environmental management practices. Future policy support towards farmers in LFAs is needed as a mix of policy instruments. Nowadays, financial support of farming in LFAs is necessary to grant farmers income, but structural support (e. g. in marketing products under reliable labelling towards consumers’ requests with trust in the “added values”) can help to increase LFA-farmers income without increasing subsidies.

description: Multi-modal multi-objective optimization problems (MMMOPs) have multiple subsets within the Pareto-optimal Set, each independently mapping to the same Pareto-Front. Prevalent multi-objective evolutionary algorithms are not purely designed to search for multiple solution subsets, whereas, algorithms designed for MMMOPs demonstrate degraded performance in the objective space. This motivates the design of better algorithms for addressing MMMOPs. The present work identifies the crowding illusion problem originating from using crowding distance globally over the entire decision space. Subsequently, an evolutionary framework, called graph Laplacian based Optimization using Reference vector assisted Decomposition (LORD), is proposed, which uses decomposition in both objective and decision space for dealing with MMMOPs. Its filtering step is further extended to present LORD-II algorithm, which demonstrates its dynamics on multi-modal many-objective problems. The efficacies of the frameworks are established by comparing their performance on test instances from the CEC 2019 multi-modal multi-objective test suite and polygon problems with the state-of-the-art algorithms for MMMOPs and other multi- and many-objective evolutionary algorithms. The manuscript is concluded by mentioning the limitations of the proposed frameworks and future directions to design still better algorithms for MMMOPs.

description: According to several surveys organic products widely meet consumers demand, but the corresponding market share in Germany is less than 2,5 %. Missing confidence in the authenticity of organic products, high prices compared to other foods, a low density of distribution, and a lack of a uniform label are regarded as hampering factors for market growth. The influence of the image of organic products on market development, however, is analyzed insufficiently by now. This paper therefore aims at investigating the implications of the image of organic foods on its acceptance by consumers and deriving hints for the development of the market. The actual study is based on a concept of morphological market research, the results refer to Germany and can be summarized as follows 1. The tradition of the image of organic products is closely associated with the production methods and some kind of ascetic lifestyle. Using those products is classified as part of this lifestyle. Consumers are impressed by a concept of living that is regarded as fundamental. On the other hand perceived changes of the products and prospects for future developments are of less relevance for the image. 2. Consumers’ blending of organic products and the ascetic lifestyle might be an important explanation for the low market share of organic products. 3. Positioning organic products within a market segment of tasteful foods necessarily needs to detach the connection between organic products and the “organic lifestyle”. This is possible by cooperating with strong brands for example on the market of frozen food or baby food. 4. Moreover, sales opportunities could arise in the segment for wellness-products because organic products are regarded as healthy and thus meet the demands for products in this segment. In any case, one might take into account the competition with other constitutional foods that are produced in a substantially different way, as e.g. dietary supplement or functional-food. Thus a strategy to benefit from these market opportunities could result in severe problems with the supplying farmers.

description: The ability to tune the wavelength of light emission on a silicon chip is important for scalable photonic networks, distributed photonic sensor networks and next generation computer architectures. Here we demonstrate light emission in a chip-scale optomechanical device, with wide tunablity provided by a combination of radiation pressure and photothermal effects. To achieve this, we develop an optically active double-disk optomechanical system through implantation of erbium ions. We observe frequency tuning of photoluminescence in the telecommunications band with a wavelength range of 520 pm, green upconversion lasing with a threshold of $340\pm 70 \; μ$W, and optomechanical self-pulsing caused by the interplay of radiation pressure and thermal effects. These results provide a path towards widely-tunable micron-scale lasers for photonic networks.

description: The efficiency of agricultural administration is analysed in this article by costs that arise in a region for administring one hectare farmland or one farm. Variances of these costs between regions can be explained by intra-organisational efficiency on the one hand and by inter-organisational efficiency on the other. Costs for the administration of 131 German regions are empirically estimated. Costs per hectare vary between DM 44 and DM 183. By regression, cost variances can be explained by the area a regional office administers and by the participation of a district office in the system, two important inter-organisational factors. A comparison of services between “cheap” and “expensive” regions does not reveal clear differences.

description: The goal of this study is to empirically evaluate the extent to which agricultural productivity estimates are affected by variation on climate. To do so, we explore the case of the agricultural sector in the Southeast US. This geographical region is influenced seasonally by the El Niño Southern Oscillation (ENSO) phenomena making it ideal for studying the interaction of climate variability and agricultural productivity. Although, different methodologies have been developed to study TE the stochastic production frontier (SPF) approach offers several advantages over other available alternatives (Kumbhakar and Lovell 2003). Thus, to assess the impact of climatic on TE we estimate alternative SPF models with and without climatic variables. We also test alternative variables to measure the influence of climate on TE; namely, seasonal rain fall and the ENSO phase.

description: This research applies a novel method of non-market valuation to the case of barrier island restoration in Mississippi. The objective is to estimate peoples’ willingness to pay (WTP) for restoration to pre-Camille status (i.e., as the barriers islands existed prior to Hurricane Camille in 1969). This is accomplished by incorporating the WTP responses for the Pre-Camille status as well as WTP data from two alternative restoration scenarios. An interval censored model was used to estimate WTP and compare WTP in both the single bounded model and the novel approach. This study found that the novel method introduced here results in higher WTP estimate: WTP under the standard single bounded model is $145.74, whereas the novel approach yields a mean WTP of $204.26.
