Physical Bounds to the Entropy-Depolarization Relation in Random Light Scattering

description: We present a theoretical study of multi-mode scattering of light by optically random media, using the Mueller-Stokes formalism which permits to encode all the polarization properties of the scattering medium in a real $4 \times 4$ matrix. From this matrix two relevant parameters can be extracted: the depolarizing power $D_M$ and the polarization entropy $E_M$ of the scattering medium. By studying the relation between $E_M$ and $D_M$, we find that {\em all} scattering media must satisfy some {\em universal} constraints. These constraints apply to both classical and quantum scattering processes. The results obtained here may be especially relevant for quantum communication applications, where depolarization is synonymous with decoherence.

description: A Sudoku puzzle often has a regular pattern in the arrangement of initial digits and it is typically made solvable with known solving techniques, called strategies. In this paper, we consider the problem of generating such Sudoku instances. We introduce a rigorous framework to discuss solvability for Sudoku instances with respect to strategies. This allows us to handle not only known strategies but also general strategies under a few reasonable assumptions. We propose an exact method for determining Sudoku clues for a given set of clue positions that is solvable with a given set of strategies. This is the first exact method except for a trivial brute-force search. Besides the clue generation, we present an application of our method to the problem of determining the minimum number of strategy-solvable Sudoku clues. We conduct experiments to evaluate our method, varying the position and the number of clues at random. Our method terminates within $1$ minutes for many grids. However, as the number of clues gets closer to $20$, the running time rapidly increases and exceeds the time limit set to $600$ seconds. We also evaluate our method for several instances with $17$ clue positions taken from known minimum Sudokus to see the efficiency for deciding unsolvability.

description: By treating the Hawking radiation as a system in thermal equilibrium, Marolf and R. Sorkin have argued that hyperentropic objects (those violating the entropy bounds) would be emitted profusely with the radiation, thus opening a loophole in black hole based arguments for such entropy bounds. We demonstrate, on kinetic grounds, that hyperentropic objects could only be formed extremely slowly, and so would be rare in the Hawking radiance, thus contributing negligibly to its entropy. The arguments based on the generalized second law of thermodynamics then rule out weakly self-gravitating hyperentropic objects and a class of strongly self-gravitating ones.

Observations of the survival of high-energy $γ$-rays over astrophysical distances can be used to place one-sided constraints on certain linear combinations of Lorentz violation coefficients in the $t$ sector at the $\sim 10^{-4}$ level of precision.

description: This paper computes and analyses total factor productivity (TFP) growth rates for tropical agricultural systems in Central-Western Africa and South-East Asia. Two regions that despite sharing common agro-ecological conditions, have pursued different adoption rates of green revolution technology and have reported dissimilar yields per hectare. A panel data set is constructed for the period 1987-2007 from the FAOSTAT database. A Bayesian stochastic frontier model with country specific temporal variation in technical efficiency is estimated. Technical efficiency estimates reveal that there is substantial room for improvement in both continental sub-sets and that TFP estimates show on average larger rates of growth for South-East Asian countries as compared to Central-Western African countries. Results indicate that TFP is mostly driven by technical change and countries such as Benin, and Gambia display catch-up.
The effects of urine storage conditions on struvite recovery
Creators: name: Tilley, Elizabeth Anne
Publisher: name: University of British Columbia
Year: 2010

description: Phosphorus, like oil, is a non-renewable resource that must be harvested from finite resources in the earth’s crust. An essential element for life, phosphorus is becoming increasingly scarce, contaminated, and difficult to extract. Struvite, or magnesium ammonium phosphate (MgNH₄P0₄.6H₂0) is a white, crystalline phosphate mineral that can be used as a bioavailable fertilizer and can be recovered from aqueous solutions such as digestor supernant. In response to diminishing water resources, increasing nutrient pollution, and largely unaffordable centralized treatment, a paradigm of Ecological Sanitation (EcoSan) has emerged. A central tenant of EcoSan technology is nutrient recovery; by separating urine from feces in the absence of water, urine can be used as a clean, concentrated nutrient source. Urine harvested in this manner is used as a liquid fertilizer with varying degrees of success and acceptance. This research examines the potential of urine to be a feedstock for struvite recovery. By recovering a sustainable source of phosphorus from urine, the prospect of appropriate sanitation and closed-loop nutrient systems, may move closer to reality. In laboratory experiments using synthetic and real human urine, different methods of preparing urine to be used as a feedstock for struvite recovery, were examined. The effect of temperature, faecal contamination, dilution, and headspace on stored nutrient levels was examined. The effect of adding different quantities of magnesium, at different times, on the amount of phosphorus that could be removed from solution, was also examined. An average of 70% of phosphorus could be removed from real urine in the form of struvite when magnesium was added to the urine solution after ureolysis had forced the precipitation of calcium and magnesium minerals; magnesium added before ureolysis began retarded the process. Dilution and the presence of wastewater were found to affect the rate of ureolysis but not the purity of the struvite recovered; recovered struvite was approximately 99% pure regardless of dilution or contamination. Based on a comparison of the results, synthetic urine was found to be representative of the general behaviour of real urine during struvite formation.

description: Combustion sources have been shown to directly emit particles smaller than 10 nm. The emission of 1-3 nm particles from biofuel or fossil fuel cookstoves has not been studied previously, nor have the radiative impacts of these emissions been investigated. In this work, emissions (number of particles) were measured during a water boiling test performed on five different cookstoves (three-stone fire, rocket elbow, gasifier, charcoal, and liquified petroleum gas [LPG]) for particle diameters between ∼1 and ∼1000 nm. We found significant emissions of particles smaller than 10 nm for all cookstoves (>5 × 1015 # kg-fuel−1). Furthermore, cleaner (e.g., LPG) cookstoves emitted a larger fraction of sub-10 nm particles (relative to the total particle counts) than traditional cookstoves (e.g., three-stone fire). Simulations performed with the global chemical transport model GEOS-Chem-TOMAS that were informed by emissions data from this work suggested that sub-10 nm particles were unlikely to significantly influence number concentrations of particles with diameters larger than 80 nm that can serve as cloud condensation nuclei (CCN) (<0.3%, globally averaged) or alter the cloud-albedo indirect effect (absolute value <0.005 W m−2, globally averaged). The largest, but still relatively minor, localized changes in CCN-relevant concentrations (<10%) and the cloud-albedo indirect effect (absolute value <0.5 W m−2) were found in large biofuel combustion source regions (e.g., Brazil, Tanzania, Southeast Asia) and in the Southern Ocean. Enhanced coagulation-related losses of these sub-10 nm particles at sub-grid scales will tend to further reduce their impact on particle number concentrations and the aerosol indirect effect, although they might still be of relevance for human health.

description: Particle isolation techniques are in the spotlight of many areas of science and engineering. In food industry, a harmful bacterial activity can be prevented with the help of separation schemes. In health care, isolation techniques are used to distinguish cancer and healthy cells or in therapy for Alzheimer's and Parkinson's diseases. We consider a cloud of Brownian particles of different sizes moving in a periodic potential and subjected to an unbiased driving as well as a constant force. We reveal an efficient separation strategy via the counterintuitive effect of negative mobility when particles of a given size are transported in a direction opposite to the applied constant force. We demonstrate a tunable separation solution in which size of the particle undergoing separation may be controlled by variation of the parameters of the external force applied to the system. This approach is an important step towards the development of point-of-care lab-on-a-chip devices.

description: Statisticians make their living producing confidence intervals and pvalues. However, those in the Stata log are not ready for delivery to the end user, who usually wants to see statistical output either as a plot or as a table. This article describes a suite of programs used to convert Stata results to one or other of these forms. The eclplot package creates plots of estimates with confidence intervals, and the listtex package outputs a Stata dataset in the form of table rows that can be inserted into a plain TeX, LaTeX, HTML, or word processor table. To create a Stata dataset that can be output in these ways, we can use the parmest, dsconcat, and lincomest packages to create datasets with one observation per estimated parameter; the sencode, tostring, ingap, and reshape packages to process these datasets into a form ready to be output; and the descsave and factext packages to reconstruct, in the output dataset, categorical predictor variables represented by dummy variables in regression models.
Orbit Simulation for the Determination of Relativistic and Solar-System Parameters for the ASTROD Space Mission

description: ASTROD (Astrodynamical Space Test of Relativity using Optical Devices) mission concept is to conduct high-precision measurement of relativistic effects,solar-system parameters and gravitational waves. In this paper, we first extend the stochastic model to simulate the determination of the masses of three big asteroids (Ceres, Vesta and Pallas). With one range observation per day for each spacecraft from 25 days to 800 days of the mission and ten range observations per day for each spacecraft from 800 days to 1050 days of the mission (when the apparent positions of the two spacecraft are close to the Sun), the accuracies of determining these parameters are 4.6*10**(-7) for gamma, 4.0*10**(-7) for beta, 1.2*10**(-8) for J2, and 6.4*10**(-5) M_Ceres, 7.6*10**(-4) M_Pallas, 8.1*10**(-5) M_Vesta for the mass determination of Ceres, Pallas and Vesta respectively. We then include in the simulation and determination the rate of change of the gravitational constant (G-dot), and an anomalous constant acceleration (aa) directed towards the Sun (Pioneer Anomaly). At the end of 1050 days of simulation, the accuracies of determining these two parameters are 9.5*10**(-15)/yr for G-dot/G and 2.0*10**(-16) m/s2 for a_a. The mass loss rate of the inner solar system is at the level of 1*10**(-13) M_Sun/yr. The accurate determinat-ion of Ġ/G will mean a need to simultaneously determine the mass loss rate. In other words, the mission gives a way to monitor the mass loss rate of the Sun if Ġ/G can be determined independently.

Inelastic response of SDOF systems subjected to subduction and crustal ground motions
Creators: name: Mattman, Dominic Willy
Publisher: name: University of British Columbia
Year: 2010

description: Structural engineers are increasing turning to nonlinear static procedures to gain better insight into the performance of the structures they design. Key to these procedures is estimating the displacement demand of the design level earthquake. The Coefficient Method, from FEMA 356 (ASCE, 2000) and recently updated in FEMA 440 (ATC, 2005), estimates this target displacement. This method was developed through statistical studies of SDOF systems utilizing crustal ground motions. Therefore, to expand the applicability of the Coefficient Method to areas subjected to subduction earthquakes such as the Pacific Northwest of North America, this study examines the behaviour of SDOF systems with 6 different hysteretic models, 50 periods of vibration, 9 relative strength values and 88 ground motions (40 from crustal sources and 48 from subduction sources). Three of the hysteretic models included in the study exhibit strength degradation with one model incorporating cyclic strength degradation while the other two included in-cycle strength degradation. Furthermore, the frequency of instability of the in-cycle strength degrading systems was examined. The greatest differences between the subduction and crustal ground motions were observed in: the inelastic displacement ratios of the EPP systems (up to 3 times higher and convergence to the "equal displacement rule" at higher periods), the inelastic displacement of the cyclic strength degrading systems when compared to EPP systems and the maximum permissible relative strength value for the in-cycle strength degrading model. With the subduction records, a moderate increase in the frequency of instability of the in-cycle strength degrading systems was also noted. Negligible differences were seen in the inelastic displacements of the cyclic and in-cycle strength degrading systems provided the later remained stable. A simple SDOF model was used to compare the response of a system retrofitted only for strength with the response of the original weak, but ductile, system. The results showed an increased displacement in the retrofitted system unless there was a significant increase in strength, the negative slope of the response was not too steep and the system had a short period of vibration.
Foreign Direct Investments as Initiators of Change: The ”Swedmilk” dairy case- Reasons behind the failure

description: Institutional problems and the corruptive use of social capital give ground for misuse of institutional gaps and cause intentional failures for financial benefits. Based on social capital theory and transaction cost economics (TCE) this paper describes how the institutional environment in the Former Yugoslav Republic of Macedonia (FYROM), affects success or failure of business endeavors, such as the Swedmilk case. Foreign Direct Investments (FDI’s) are expected to be the drivers of positive economic development for economies in transition. Hence, the major question addressed in this paper is: How does a Greenfield foreign direct investment of 25 million Euros, manage to collapse in such a short period? The paper also describes the “official” plans and actual outcomes of the dairy, as well as the situation in the dairy sector before and after the Swedmilk failure. The financial problems occurred in October 2008, so the case of Swedmilk is quite recent and has not been included in any kind of research. Being a recent case the real implications on the dairy farming and sector are yet to be explored.

description: In 2015, the New Horizons spacecraft flew past Pluto and its moon Charon, providing the first clear look at the surface of Charon. New Horizons images revealed an ancient surface, a large, intricate canyon system, and many fractures, among other geologic features. Here, we assess whether tidal stresses played a significant role in the formation of tensile fractures on Charon. Although presently in a circular orbit, most scenarios for the orbital evolution of Charon include an eccentric orbit for some period of time and possibly an internal ocean. Past work has shown that these conditions could have generated stresses comparable in magnitude to other tidally fractured moons, such as Europa and Enceladus. However, we find no correlation between observed fracture orientations and those predicted to form due to eccentricity-driven tidal stress. It thus seems more likely that the orbit of Charon circularized before its ocean froze, and that either tidal stresses alone were insufficient to fracture the surface or subsequent resurfacing remove these ancient fractures.

description: Diese Arbeit hat den Entwurf eines Flussschwimmbades im Hauptstrom der Donau auf Höhe des Handelskais zum Thema. Dieses Schwimmbad soll gezielt die vorhandene Strömung leiten, um so Wasserbereiche mit unterschiedlichen Qualitäten zu erzeugen. Dadurch soll sich das Bad klar von den schon bestehenden Frei- & Hallenbädern der Stadt Wien abheben. Gleichzeitig soll es der Bevölkerung Anreiz zur Belebung des öffentlichen Raumes des Rechten Donauufers bieten. Zuerst wird die Beziehung zwischen Wien und der Donau geschichtlich aufgearbeitet. Aus dieser geht auch der gewählte Projektstandort hervor, der genauer überprüft wird. Zur Präzisierung des Entwurfes werden numerische Strömungsanalysen durchgeführt und die Schwimmbarkeit der Konstruktion überprüft. Ein Vergleich mit anderen Fluss- & Naturbädern größerer Städte setzt das Projekt in einen großräumlicheren Kontext.
description: This thesis formulates a design for a river swimming facility in the danube near Handelskai. Swimming areas of different qualities should be created through specific channeling of the existing water current. This feature lets the facility stand out between the existing inand outdoor baths of vienna. At the same time it should stimulate the acceptance and use of the publc space at the righthanded riverside of the danube. First of all the history between the city vienna and the river danube is analised. As a conclusion the chosen project location is further examined. Numeric flow analysis enrich the design process. The floatability of the construcion is checked to acchieve a concrete project. Contextualisation at a broader level is given by comparison with other river and sea baths in large cities.

For example, in a sequence of events in which several outcomes are possible and the length of the sequence and number of outcomes of each type known, the number of runs gives an indication of whether the outcomes are random, clustered, or alternating. This note explains and illustrates a simple method of random shuffling that is often useful. We show how the conditional probability distribution of the number of runs may be derived easily in Stata, thus yielding p-values for testing the null hypothesis that the type of outcome is random. We also compare our direct approach with that using the simulate command.

description: Neutron-induced reactions on unstable isotopes play a key role in the nucleosynthesis $i$--, $r$--, $p$--, $rp$-- and $νp$--processes occurring in astrophysical scenarios. While direct cross section measurements are possible for long-living unstable isotopes using the neutron Time-of-Flight method, the currently available neutron intensities ($\approx10^{6}$ n/s) require large samples which are not feasible for shorter lifetime isotopes. For the last four decades, the $^{7}$Li$(p,n)$ reaction has been used to provide a neutron field at a stellar temperature of $\approx$ 0.3 GK with significantly higher intensity, allowing the successful measurement of many cross sections along the $s$-process path. In this paper we describe a novel method to use this reaction to produce neutron fields at temperatures of $\approx$ 1.5-3.5 GK, relevant to scenarios such as convective shell C/Ne burning, explosive Ne/C burning, and core-collapse supernovae. This method will allow direct cross section measurements of many important reactions at explosive temperatures, such as $^{26}$Al$(n,p)$, $^{75}$Se$(n,p)$ and $^{56}$Ni$(n,p)$.

description: In earlier studies, past succession is found to contribute positively to the farm growth. However, there is lack of information on how are the farms succeeding after the starting phase. In this study, it is analysed how farmers that have recently started their farm enterprise differ from more experienced farmers in some key farm management areas such as farm and farmer characteristics, strategic objectives and development plans. The data were collected by postal survey from Salo region in South-Western Finland. In the study, farmers are divided in to three different groups according to the farmer’s age and experience. According to the results, early phase farmers are in certain areas better equipped than older generations. They have better education and better networks than others. Moreover, the younger entrepreneurs consider their networks more important than their senior colleagues. Like expected, at early phase farmers had invested significantly more and have more liabilities than the others. In addition, the early phase farmers are the most active also for developing their farms. The late phase farmers were the least active, even if they were going to have succession within the next years. This might be problematic for the successor, too. However, in order to improve the viability of whole farming sector, the farms should be developed as continuum.

description: Brain-imaging data have been increasingly utilized to understand intellectual disabilities. Despite significant progress in biomedical research, the mechanisms for most of the intellectual disabilities remain unknown. Finding the underlying neurological mechanisms has proved difficult, especially in children due to the rapid development of their brains. We investigate verbal reasoning, which is a reliable measure of an individual’s general intellectual abilities, and develop a class of high-order imaging regression models to identify brain subregions which might be associated with this specific intellectual ability. A key novelty of our method is to take advantage of spatial brain structures, and specifically the piecewise smooth nature of most imaging coefficients in the form of high-order tensors. Our approach provides an effective and urgently needed method for identifying brain subregions potentially underlying certain intellectual disabilities. The idea behind our approach is a carefully constructed concept called Internal Variation (IV). The IV employs tensor decomposition and provides a computationally feasible substitution for Total Variation (TV), which has been considered suitable to deal with similar problems but may not be scalable to high-order tensor regression. Before applying our method to analyze the real data, we conduct comprehensive simulation studies to demonstrate the validity of our method in imaging signal identification. Next, we present our results from the analysis of a dataset based on the Philadelphia Neurodevelopmental Cohort for which we preprocessed the data including re-orienting, bias-field correcting, extracting, normalizing and registering the magnetic resonance images from 978 individuals. Our analysis identified a subregion across the cingulate cortex and the corpus callosum as being associated with individuals’ verbal reasoning ability, which, to the best of our knowledge, is a novel region that has not been reported in the literature. This finding is useful in further investigation of functional mechanisms for verbal reasoning.
NE-165 Case Study: The Fresh Company

description: "Koninklijke Ahold nv" (Royal Dutch Ahold) was the leading food retailer in The Netherlands in 1990 with an approximately 36% share of the food and grocery market. Moreover, its four U. S. companies (Giant Food Stores, PA.; Bi-Lo, NC.; Finast, OR.; and Tops Friendly Markets, NY) ranked it number ten among the largest U. S. food retailers . Despite this dominance and obvious knowledge of food wholesale and retail distribution, Ahold had historically been unable to capture a satisfactory share of the fresh food business in The Netherlands. Yet this business represented approximately $7 billion in current business and, perhaps more importantly, was thought by many to hold the key to future success in the food industry. The case study documents the set of circumstances that led Ahold to experiment with a new food store format that, its management hoped, would allow a more effective penetration of the fresh food business. A project director is appointed with the assignment to build a new fresh foods business. The case describes his initial actions and presents the rather disappointing results after the store had been opened nine months. Part '~A" of the case ends with an outline of the areas that the project director feels merit strategic redirection in order to achieve more acceptable performance. Part "B" of the case summarizes the actions incorporated into a new strategic marketing plan in hopes to salvage the project. New financial results, nine months after the repositioning, are presented.

Demand and Price Analysis

description: This paper estimates the relationships between market structure and the Lerner index of monopoly constructed from price data on processed food products sold through grocery stores. A theoretical model of a differentiated oligopoly specifies two determinants of price-cost margins: the Herfindahl-Hirschman index of seller concentration adjusted for the elasticity of demand and the industry advertising-to-sales ratio. The results indicate that the three principal determinants of price-cost margin variation, in order of their impacts, are: advertising intensity, elasticity of demand, and concentration. Previous structure-performance studies that did not incorporate the elasticity of demand were probably misspecified.

description: FAO measure of undernourishment is calculated based on three main parameters: dietary energy supply (DES), minimum dietary energy requirement (MDER), and the coefficient of variation of dietary energy consumption (CV). In the current implementation of this methodology, the DES and the MDER change over time, as would be expected. The CV, however, remains constant. However, we expect the CV to change over time and be a function of income and prices. This paper discusses why the CV should change in response to changes in these variables, and suggests a practical way to estimate changes in the CV over time in the absence of survey data.

description: Following their introduction in 1992, direct payments have become one of the main instruments of the Common Agricultural Policy. The aim of this study is to analyse potential scenarios of harmonization of direct payments in the CAP post-2013. In doing so, we use the CAPRI model, which represents the functioning of agricultural markets at the global level and simultaneously models CAP measures at the EU regional level. Results suggest that while a flatter rate of direct payments would have minor impacts on agriculture at the EU level, it would imply substantial redistributive effects, both across regions and Member States.
Effects of Destriping Errors on Estimates of the CMB Power Spectrum

description: Destriping methods for constructing maps of the Cosmic Microwave Background (CMB) anisotropies have been investigated extensively in the literature. However, their error properties have been studied in less detail. Here we present an analysis of the effects of destriping errors on CMB power spectrum estimates for Planck-like scanning strategies. Analytic formulae are derived for certain simple scanning geometries that can be rescaled to account for different detector noise. Assuming {Planck-like low-frequency noise, the noise power spectrum is accurately white at high multipoles (l<50). D estriping errors, though dominant at lower multipoles, are small in comparison to the cosmic variance. These results show that simple destriping map-making methods should be perfectly adequate for the analysis of Planck data and support the arguments given in an earlier paper in favour of applying a fast hybrid power spectrum estimator to CMB data with realistic `1/f' noise.

description: The factor H (FH) protein family is emerging as a complex network of proteins controlling the fate of the complement alternative pathway (AP) and dictating susceptibility to a wide range of diseases including infectious, inflammatory, autoimmune, and degenerative diseases and cancer. Composed, in man, of seven highly related proteins, FH, factor H-like 1, and 5 factor H-related proteins, some of the FH family proteins are devoted to down-regulating the AP, while others exert an opposite function by promoting AP activation. Recent findings have provided insights into the molecular mechanisms defining their biological roles and their pathogenicity, illustrating the relevance that the balance between the regulators and the activators within this protein family has in defining the outcome of complement activation on cell surfaces. In this review we will discuss the emerging roles of the factor H protein family, their impact in the complement cascade, and their involvement in the pathogenesis of complement-mediated diseases associated with the AP dysregulation.

description: The economies of developed countries have, since 2007, experienced the most significant and persistent period of economic malaise since the 1930s. Domestic economic policies have failed to revive sustained economic growth and, as a result, unemployment remains at levels that voters find difficult to accept. In addition, without tax revenue-enhancing growth, government deficits persist, and borrowing to finance the cumulative deficits has become increasingly difficult for some countries. With domestic policies largely exhausted, but economic growth elusive, policy makers have been considering external policies as a means to stimulate their economies. Trade protectionism and strategic devaluation are potential policies. The lessons of the 1930s regarding the dangers of beggar thy neighbour protectionism appear to retain their currency with policy makers, but the same may not be true for strategic devaluation. The article outlines the likely poor efficacy of strategic devaluation as a politically convenient mechanism to escape the current economic malaise.

description: Mediation analysis is of rising interest in epidemiology and clinical trials. Among existing methods, the joint significance (JS) test yields an overly conservative type I error rate and low power, particularly for high-dimensional mediation hypotheses. In this article we develop a multiple-testing procedure that accurately controls the family-wise error rate (FWER) and the false discovery rate (FDR) when testing high-dimensional mediation hypotheses. The core of our procedure is based on estimating the proportions of component null hypotheses and the underlying mixture null distribution of p-values. Theoretical developments and simulation experiments prove that the proposed procedure effectively controls FWER and FDR. Two mediation analyses on DNA methylation and cancer research are presented: assessing the mediation role of DNA methylation in genLetic regulation of gene expression in primary prostate cancer samples; exploring the possibility of DNA methylation mediating the effect of exercise on prostate cancer progression. Results of data examples include wellL-behaved quantile-quantile plots and improved power to detect novel mediation relationships. An R package HDMT implementing the proposed procedure is freely accessible in CRAN.

description: The paper deals with the analysis of market land prices that were collected from land purchased contracts in the Czech Republic. Regression model was used to identify determinants explaining variability of market prices between 2008 and 2009. It was found out that type of plantation, region, type of buyers, plot size, distance to regional city or number of parcels play significant role. These factors explain more than a half of variance in land price. Quality of land that was expressed through administrative price has significant effect on market price. Yet, such effect became less import in regions nearby cities (e.g. Prague and Olomouc), where the market land price is significantly influenced by the distance to the district city. Land reform, however has not been confirmed to stimulate higher prices for sellers. It is reasonable to expect that part of the remaining variation could still be accounted for by non-random variables.

description: As a result of technological progress ICT (Information and Communication Technologies) has created the so-called „digital divide“. Some people are unable to individually respond to this progress, but the proper use of ICT can help them overcome this handicap. One of the possibilities is to create accessible and usable applications depending on the character and level of disability. In accordance with the European CertiAgri project, e-learning tools are used for integrating people with disabilities into the horticultural area. The paper specifically describes examples of simple teaching aids from the practical „green care“ course, which focus on the skills of people with mental disabilities.
