EVALUATION OF EFFICIENCY OF LAND RECLAMATION IN RUSSIA
Creators: name: Kireycheva, Lyudmila
Publisher: name: JOURNAL OF AGRICULTURE AND ENVIRONMENT
Year: 2018

description: According to the natural and climatic conditions, Russia is located in a zone of risky agriculture: there is a precipitate deficit on 80% of arable land, and excessive over moistening on 10% of arable land. This is also complicated by climate aridization. In drought years it is practically impossible to implement intensive agrotechnologies and adaptive-landscape farming systems without the use of land reclamation. Currently, in Russia, the total area of irrigated lands is 4.27 million hectares and 4.8 million hectares of drained lands. The average productivity of irrigated land is 2.9 tonnes of grain units/ha. In the case of land reclamation, it is possible to increase the productive potential by 3-4 times. The methodology of increasing the productive potential of agricultural lands by irrigation and drainage reclamation based on the energy evaluation of land reclamation activity is proposed. The energy assessment includes the calculation of the bioclimatic potential, the energy assessment of the state of the soil and the vegetation cover. For the energy estimation of land reclamation, a new indicator is proposed a turbulent energy output, the difference between the radiation balance, the energy of soil formation, and the energy accumulated in soil humus and crop production. This makes it possible to predict the productive potential of agricultural land, depending on the amount of energy invested in land reclamation. The proposed approach makes it possible to move from a real evaluation to a unified energy estimate. The calculations of productivity according to the developed method for various natural zones of the European part of Russia are performed. Chernozems showed the greatest productive potential. It reaches 7.7 tonnes of grain units/ha, and in case of irrigation it can increase up to 10-12 tonnes/ha; the productivity of sod podzol and gray forest soils under natural conditions does not exceed 1.3-2.0 tonnes of grain units/ha, while irrigation productivity will increase to 6-8 tonnes of grain units/ha. Irrigation in the semi-desert and desert zones of the European part of Russia allows increasing their productivity up to 5 times. The proposed method allows selecting the most favorable zoning soils for the reclamation, justifying the crops that ensure the maximum yield in these soil and climatic conditions. The article shows that food security will be ensured during the development of land reclamation in soil and climatic conditions of excessive and insufficient moisture.

description: This paper focuses on linkage between new rice seed varieties and production risk and also factors affecting adoption of these varieties in Iran. Farm-level data were collected from a sample of 154 rice farms located in two major districts of Fars province in Southern Iran for 2001-02. The risk-premium associated with the use of seed is estimated following by analyzing a moment-based production risk approach. The results show that the risk premium increases with new seed varieties in the lack of appropriate production conditions implying that new seed varieties is a riskincreasing input and involves a higher cost of risk. However, under suitable production conditions, the cultivation of new rice varieties on average ensures greater yield and at the same time involves less risk as measured by the risk premium. Also, results indicate that the farmer-specific relative risk premium proxies for the risk attitudes of each farmer have negative and significant effect on the decision to adopt new seed varieties. Therefore, farmers that are more riskaverse with respect to their use of seed are less likely to adopt new seed varieties and allow them to decrease their production risk arising from seed requirements.

An improved sample size calculation method for score tests in generalized linear models

Subjects: subject: Methodology (stat.ME)

description: Self and Mauritsen (1988) developed a sample size determination procedure for score tests in generalized linear models under contiguous alternatives. Its performance may deteriorate when the effect size is large. We propose a modification of the Self-Mauritsen method by taking into account of the variance of the score statistic under both the null and alternative hypotheses, and extend the method to noninferiority trials. The modified approach is employed to calculate the sample size for the logistic regression and negative binomial regression in superiority and noninferiority trials. We further explain why the formulae recently derived by Zhu and Lakkis tend to underestimate the required sample size for the negative binomial regression. Numerical examples are used to demonstrate the accuracy of the proposed method.

description: Value-enhanced crops (VEC's) have been the focus of "second-generation" genetically modified (GM) crops. The market power granted by intellectual property rights (IPR) and the use of contractual arrangements in VEC gene and seed production have fostered a move toward tightly-aligned supply chain industries. This paper suggests and tests an analytical methodology for examining a number of issues in tightly-aligned supply chain industries: (1) the distributions of potential monopolistic and monopsonistic rents, (2) choices of licensing intellectual property versus in-house seed production and distribution (3) implications of alternative marketing strategies and elasticities of demand on the magnitudes of rents, and (4) determining impacts on different stages within the supply chain and on substitute commodities. The high-oil corn industry is used as a case study.

description: We report an experimental investigation of the statistical time dynamic of spatial Fourier modes in a fully developped turbulent jet flow. Measurements rely on an original acoustic scattering technique, allowing the direct and continuous probing in a time of spatial Fourier modes of the turbulent vorticity field at well defined spatial wavevectors. From the recordings of the amplitude of the spatial Fourier modes corresponding to different wavevectors in the inertial range, we compute the time correlation functions of the modal amplitude. The modal vorticity dynamics exhibits two well separated time scales: a short one which is scale dependant and related to the well known sweeping effect (random advection), and a much longer one, of order the integral time scale, which is not scale dependent. By computing the cross-correlation of the amplitude of two different wavevectors, we evidence a clear statistical dependance between scales, whatever their separation, at variance with the original Kolmogorov 41 theory. We ascribe our experimental results to a manifestation of a new type of statistical intermittency. We call this new statistical feature a large scale time intermittency effect, in contrast with the usual small scale spatial intermittency reported in Eulerian velocity measurements. We propose to attribute this time intermittency, to the fluctuations in time of the injected energy at large scale, in the spirit of the objection formulated by Landau against the K41 theory.

description: This paper derives sufficient conditions (in terms of supply and demand elasticities) for producers to gain under different supply shifts when supply and demand are specified to be linear functions and supply is inelastic. It is shown that regardless of the type of supply shift, producers lose whenever the sum of absolute values of supply and demand elasticities is less than one, while they gain when production takes place in the elastic portion of the demand. In all other cases arising from alternative elasticity configurations simple formulas developed in this paper may be used to determine the direction of change in producers surplus.
Improving Efficiency of Training a Virtual Treatment Planner Network via Knowledge-guided Deep Reinforcement Learning for Intelligent Automatic Treatment Planning of Radiotherapy

description: We previously proposed an intelligent automatic treatment planning framework for radiotherapy, in which a virtual treatment planner network (VTPN) was built using deep reinforcement learning (DRL) to operate a treatment planning system (TPS). Despite the success, the training of VTPN via DRL was time consuming. Also the training time is expected to grow with the complexity of the treatment planning problem, preventing the development of VTPN for more complicated but clinically relevant scenarios. In this study we proposed a knowledge-guided DRL (KgDRL) that incorporated knowledge from human planners to guide the training process to improve the training efficiency. Using prostate cancer intensity modulated radiation therapy as a testbed, we first summarized a number of rules of operating our in-house TPS. In training, in addition to randomly navigating the state-action space, as in the DRL using the epsilon-greedy algorithm, we also sampled actions defined by the rules. The priority of sampling actions from rules decreased over the training process to encourage VTPN to explore new policy that was not covered by the rules. We trained a VTPN using KgDRL and compared its performance with another VTPN trained using DRL. Both VTPNs trained via KgDRL and DRL spontaneously learned to operate the TPS to generate high-quality plans, achieving plan quality scores of 8.82 and 8.43, respectively. Both VTPNs outperformed treatment planning purely based on the rules, which had a plan score of 7.81. VTPN trained with 8 episodes using KgDRL was able to perform similarly to that trained using DRL with 100 episodes. The training time was reduced from more than a week to 13 hours. The proposed KgDRL framework accelerated the training process by incorporating human knowledge, which will facilitate the development of VTPN for more complicated treatment planning scenarios.

description: Agriculture productivity varies dramatically in different regions of the world. Using recent theories of economic growth and recently provided data sets, this study finds some empirical regularities between agricultural labour productivity growth, investment and education, as well as environmental factors, for 44 countries during the period 1980-1993. I find strong evidence that where agricultural investment and educated people rates are higher, agricultural labour productivity grows faster. Secondly, geographical factors as well as freer trade influence growth. Finally, I find evidence of conditional convergence, which means that cross-country agricultural productivity does not converge to the same level of steady-state but that productivity in each country converges to its own long-run equilibrium.

description: We report on the transport properties of a high mobility two-dimensional hole system (2DHS) confined in GaAs/AlGaAs quantum wells grown molecular-beam epitaxy on the (100) surface of GaAs. The quantum wells are modulation-doped with carbon utilizing a novel resistive filament source. At T=0.3K and carrier density p=1x10^11cm^-2, a mobility of 10^6cm^2/Vs is achieved. At fixed carrier density p=10^11cm^-2, the mobility is found to be a non-monotonic function of the quantum well width. The mobility peaks at 10^6cm^2/Vs for a 15nm well and is reduced for both smaller and larger well widths for these (100) samples. The mobility anisotropy is found to be small. Mobility along (0\bar11) is approximately 20% higher than along the (011) direction. In addition, the low temperature carrier density is found to have low sensitivity to light. The hole density increases by only ~10% after exposure to red light at T=4.2K. In structures designed for a lower carrier density of 3.6x10^10cm^-2, a mobility of 800,000cm^2/Vs is achieved at T=15mK.

description: Nonparametric (Kernel) regression analysis and micro-data from the Family Budget Survey (FBS) are used in this paper to estimate and to compare the Engel curves for food demand of the urban and the rural households. The empirical results suggest that the Characteristic Substitution Effects (CSEs) are not constant but vary considerably with the total consumption outlay. They also suggest that the Working-Leser hypothesis, according to which shares are linear in logarithmic expenditure, is consistent with the food demand patterns in Greece.

description: The maximal acceleration (MA) problem associated with the position-dependent rest mass concept is considered. New arguments in favor of the mass-dependent maximal acceleration (MDMA) are put forward. The hypothesis that there exists a maximal force with the numerical value equal to the inverse Einstein's gravitation constant is advanced. The Lagrangian and Hamiltonian classical dynamics of a point-like particle with the coordinate-dependent mass is given. The effective Lagrangian for the pure gravitational interaction of a test particle is proposed. Within the scope of this model the typical spiral galaxy rotation is described. It is shown that by this model the peculiar form of the corresponding rotation curve is as a whole reproduced without recourse to the dark matter concept. Also, it is demonstrated that the canonical quantization of this model leads directly to the Dirac oscillator model for a particle with Plank's mass.

description: We generalize the geometrical formulation of Wilson loops recently introduced in arXiv:2003.01729v2 to the description of Wilson Surfaces. For N=(2,0) theory in six dimensions, we provide an explicit derivation of BPS Wilson Surfaces with non-trivial coupling to scalars, together with their manifestly supersymmetric version. We derive explicit conditions which allow to classify these operators in terms of the number of preserved supercharges. We also discuss kappa-symmetry and prove that BPS conditions in six dimensions arise from kappa-symmetry invariance in eleven dimensions. Finally, we discuss super-Wilson Surfaces - and higher dimensional operators - as objects charged under global $p$-form (super)symmetries generated by tensorial supercurrents. To this end, the construction of conserved supercurrents in supermanifolds and of the corresponding conserved charges is developed in details.

description: We experimentally and theoretically consider highly condensed planar brushes made of charged polymers. Using x-ray reflectivity on polyelectrolytes which are anchored at the water-air interface, it is shown that such strongly stretched brushes show a slight but detectable height variation upon lateral compression. This stands in contrast to the well-accepted scaling relation in the so-called osmotic brush regime, which predicts the brush height to be independent of the grafting density. Similar effects are seen in simulations on highly compressed charged brushes. Scaling arguments which go beyond the linear approximation for the entropy of confined counterions and for weak chain-stretching are able to explain those findings on a semi-quantitative level.

In the company of music and illness : the experience and meaning of music listening for women living with chronic illness
Creators: name: Nicol, Jennifer James
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to contribute an experiential understanding of everyday "music listening experiences through a text that also conveyed a pathic way of knowing. I studied the phenomenon of music listening in the particular context of women living with chronic illness (i.e., a physical condition that is managed rather than cured), and in keeping with van Manen's (1990, 2000) applied hermeneutic-phenomenological approach. Van Manen's approach to phenomenological inquiry emphasizes implementation of the reductio (the reduction), attention to the vocatio (the vocative dimension), and the use of empirical and reflective methods to generate and analyze data. The question that guided this study was: What is the lived experience and lived meaning of music listening for women living with chronic illness? Six women were interviewed in multiple conversations about their music listening experiences. All lived with chronic illness, and identified music listening as important in their lives. Following an initial analysis based on multiple readings from holistic, selective, and detailed perspectives, I used a guided existential reflection based on lived body, lived time, lived space, and lived relation to further understand, organize, and reveal the many ways in which the women listened to music. Writing and rewriting in a reflective and dialogical manner were grounding elements of analysis. Findings contribute in several ways. Most broadly, the final text was constructed to communicate an understanding that is embodied and discursive (i.e., knowledge as participation), and that leads to personal formative knowledge (i.e., knowledge as being). As a phenomenology of music listening, results suggested that to listen to music is to be in the company of music; that is, to be with a longtime companion who ultimately aids in accommodating the unanticipated arrival of chronic illness. Implications include future research to further investigate the complex, relational dynamics associated with music listening experiences, as well as the possibility of the body as a source of knowledge (i.e., mind-body), acting as a musical compass in music listening experiences. Implications for counselling practice are also described.

description: The effect of characteristics of pig enterprise and its owner, along with management applied in farms on regional pig meat productivity of commercial pig units in Greece was examined. The results showed that most of the enterprises were family operated, belonging to a sole owner of old age and low educational level, whose children were not involved or plan to get involved with the enterprise. The analysis of a generalised linear model showed that only the "Age of farm's equipment" and "Size class of sow herd' were significant in explaining the variation of pig meat productivity.

description: In this paper we expanded the security of a central broadcast protocol using thermal states to the case in which the eavesdropper controls the source. Quantum secrecy in a continuous variable central broadcast scheme is guaranteed by the quantum correlations present in thermal states arising from the Hanbury Brown and Twiss effect. This work allows for a method of key exchange in which two parties can agree a key as long as both can detect the same source and they are within the spatial coherence length of the source. This is important because it allows quantum secure key exchange with only minimal changes to existing infrastructure.

description: It is logically acceptable in a true premise to say that there exist multiple effects in various activities taking place from the land to the environment. These effects are now spreading rapidly making human, animals, air, soil, water, plants, and planet even more vulnerable to multiple exposures. Interestingly, agriculture and environment are both interrelated and connected but only human action depicts the simultaneous cohesion which brings contradictions in them. The Nigerian soil in Niger Delta has witnessed this malady for over 50 years without remedies around the corner. Unsustainable pattern of natural resources consumption has witnessed 83% of oil spills leeched into arable land and 17% in the swampy areas within one year and two months in some selected places recorded. A development which continually promote degradation of the natural ecosystem, affecting forest, agricultural production, and environmental sustainability. It has posed a threat, challenging both the present and future sustainable agricultural production, and human survival especially in this region. To support both present and future economic sustenance of the Nation at large, the natural resources exploitation requires green production activities to correct three ways adversely affecting how human beings use the environment to sustain their productive life as discussed in the methodology. This paper cross-examines the incongruity created due to anthropogenic activities by the unwise use of the natural resources in the environment leading to disproportionate forestation, poverty, agricultural poor yields, loss of environmental services and biodiversity. Consequently, the study objective is specifically concerned about the serious challenges facing the long-term environmental problems of oil spillages on forest and agricultural sustainability in the Niger Delta region. The study gives more insight into future sustainable planning using Multiple Exposures Multiple Effects (MEME) model analysis. It will benefit the community, public and private institutions, government agencies, policy-makers, stakeholders among others.

description: We provide empirical evidence on labour supply and inequality for wage-earning farm households in Spain, using two cross-sections from 1991 and 1994. The fundamental results can be divided into two groups. With respect to the labour supply: i) household size has a positive effect on male supply and a negative effect on female supply; ii) if there are children younger than 4, the female supply reduces, whereas that corresponding to males increases; iii) if the housing area is Andalusia or Extremadura, this reduces the number of worked hours by both spouses and iv) the income elasticities are negative, and both the male and female labour supplies are increasing. As regards the welfare analysis: i) monetary income is a good welfare indicator; ii) welfare inequality is lower than income inequality and, finally, iii) inequality among the wage-earning farm households in Spain has increased between 1991 and 1994.

description: Shared control schemes allow a human driver to work with an automated driving agent in driver-vehicle systems while retaining the driver's abilities to control. The human driver, as an essential agent in the driver-vehicle shared control systems, should be precisely modeled regarding their cognitive processes, control strategies, and decision-making processes. The interactive strategy design between drivers and automated driving agents brings an excellent challenge for human-centric driver assistance systems due to the inherent characteristics of humans. Many open-ended questions arise, such as what proper role of human drivers should act in a shared control scheme? How to make an intelligent decision capable of balancing the benefits of agents in shared control systems? Due to the advent of these attentions and questions, it is desirable to present a survey on the decision-making between human drivers and highly automated vehicles, to understand their architectures, human driver modeling, and interaction strategies under the driver-vehicle shared schemes. Finally, we give a further discussion on the key future challenges and opportunities. They are likely to shape new potential research directions.

description: The effect of characteristics of pig enterprise and its owner, along with management applied in farms on regional pig meat productivity of commercial pig units in Greece was examined. The results showed that most of the enterprises were family operated, belonging to a sole owner of old age and low educational level, whose children were not involved or plan to get involved with the enterprise. The analysis of a generalised linear model showed that only the "Age of farm's equipment" and "Size class of sow herd" were significant in explaining the variation of pig meat productivity.

description: Two-particle correlations based on the multiplicity of selected isobars are found to be sensitive to the parameterization of the fragments' binding energies and the breakup volume assumed in the model calculations. The properties of these correlations have been examined in the framework of the Statistical Multifragmentation Model as a function of the breakup temperature. The model calculations suggest that the maxima of these correlation functions occur at well separated temperatures as the breakup volumes used in the model vary from 3 to 6 times that at normal density. These volumes are within the range assumed in most statistical calculations and supported by experiments. Besides their position, the height and width of the maxima are also found to be sensitive to the parameterization of the fragments' binding energy. The magnitude of all these effects also depends on the isobars considered in the correlations. We found that, due to an interplay between the symmetry energy and the volume dependent terms of the Helmholtz free energy, in the case of nearly symmetric sources, correlations involving light mirror nuclei seem to enhance these effects. We suggest that the proposed correlation functions could be used to extract information on the fragments' energies and on the breakup volume of nuclear sources.

description: This article is concerned with the management of water resources in the region of Western Macedonia. Taking into account the great importance of agriculture as the principal consumer of water in the region, as well as the drastic increase in regional water consumption over the last decade, a related study evaluating the demand patterns for irrigated water can prove to be extremely valuable. This paper examines the demand patterns and probable trends for irrigated water using the Discrete Sequential Stohastic Programming (DSSP) Model for four agricultural products (apples, peaches, potatoes and tomatoes) and five specific subareas (the prefecture of Florina, the prefecture of Kastoria, the prefecture of Grevena, the city of Kozani and the city of Ptolemaida). Results clearly demonstrate that apples and potatoes are the only crops in the region that use water deficit irrigation strategies in short water years (representing a water deficit of 25%). In addition, results reveal that the most cost-effective solution would be to acquire water from the prefecture of Kastoria because the marginal value of run-off water in this area is lower compared to the other areas in question.

description: The study of the impact of anthropogenic factors on natural soil is possible to trace when studying natural soil agrogenic catenas. This research was conducted on Southern Primorie in the experimental fields. Granulometric composition of the soil catena first element is coarse-silty light loam. In general, studied soils have low anti-erosion resistance. These soils have enough water-stable structure and a satisfactory ability to aggregation in agrohumic horizon. In the eluvial horizon metamorphic indicators erosion constants decrease, suggesting greater vulnerability of soil material by water currents. In general, studied soils have low anti-erosion resistance. Second element of the soil catena have stable homogeneous particle size distribution throughout the soil profile: silty light clay - light silty clay sandy - silty clay medium - light silty clay. Ability to aggregation is sufficient in all genetic horizons. Anti-erosion resistance is high. Third element of the soil catena have heavy granulometric composition in general. Erosion resistance of soil, based on the results obtained structural factors and the factor of dispersion, as well as at special erosion studies the authors confirmed the high stability of the erosion control of dark humic horizon, average - gley stability and low erosion control - parent rock. The content of heavy metals in agrogenic soil catena isn´t exceeds the maximum allowable concentration (MAC). Studying catena is representative to the conditions of formation of soils across agrogene Southern Primorie floodplain hilly - ridged district.

description: X-ray background surveys indicate the likely presence of diffuse warm gas in the Local Super Cluster (LSC), in accord with expectations from hydrodynamical simulations. We assess several other manifestations of warm LSC gas; these include anisotropy in the spatial pattern of cluster Sunyaev-Zeldovich (S-Z) counts, its impact on the CMB temperature power spectrum at the lowest multipoles, and implications on measurements of the S-Z effect in and around the Virgo cluster.

description: A photometric study of 22 disk galaxies at redshifs z=0.5-2.6 is conducted, using deep NICMOS J and H band and STIS open mode observations of the HDF-S NICMOS parallel field. Rest-frame B-profiles and (U-V) color profiles are constructed. A number of disks show steeper decrease of luminosity than exponential, referring to disk truncation. Shape of the luminosity profiles does not vary with redshift, but galactic sizes decrease significantly. (U-V) colors and color gradients suggest more intense and centrally concentrated star formation at earlier epochs. On the basis of (U-V) color and chemical evolution models, the disks at z~2.5 have formed between z=3.5-7. The studied parameters are idependent of absolute B luminosity within the sample.
