description: In 1996 and 2016, respectively, the Independent Creative Group (ICG) conducted a comprehensive sociological study "Economic reform - the eye of the village." The aim of the project was to explore the evaluation of economic reform of rural populations in 5 areas: a) economic reform; b) quality of life and expectations; c) businesses; d) agricultural transformation; e) development of farming. The research was conducted in the form of "sociological fixation" expectations, estimates and other reactions to social challenges. The object of the study was a typical village of the Lviv region. The study confirmed the simultaneous increase of confidence in economic transformation and the growth of pessimism in the impact of reforms. The rural population understands the goals and objectives of reforms, and supports private property and the market economy. The standard of living has improved significantly, but it does not cover the real expectations of the population. Farmers understand the role and importance of entrepreneurship and accept new business entities. The study showed significant structural changes in the views and assessments of rural residents of the Lviv region. There is obvious public awareness of fundamental lifestyle changes in the countryside.

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: The current noise spectrum of a single-electron transistor (SET) coupled to a nano-mechanical resonator is calculated in the classical regime. Correlations between the charge on the SET island and the position of the resonator give rise to a distinctive noise spectrum which can be very different from that of the uncoupled SET. The current noise spectrum of the coupled system contains peaks at both the frequency of the resonator and double the resonator frequency, as well as a strong enhancement of the zero-frequency noise. The heights of the peaks are controlled by the strength of the coupling between the SET and the resonator, the damping of the resonator, and the temperature of the system.

The objective of this paper was to evaluate upon the basis of the Global Food Security Index, the overall food security situation in the European Union states. The countries are divided into two groups. The first is composed of fourteen selected states from the EU -15 and the second group is six selected states from the EU-13. In addition to the Food Security Index, the Food Affordability, Food Availability, and the Food Quality and Safety Indexes were also analyzed. The research data were obtained from the authors‘ own research based on the Global Food Security Index Report, and from FAO.

Predictability sieve, pointer states, and the classicality of quantum trajectories

description: We study various measures of classicality of the states of open quantum systems subject to decoherence. Classical states are expected to be stable in spite of decoherence, and are thought to leave conspicuous imprints on the environment. Here these expected features of environment-induced superselection (einselection) are quantified using four different criteria: predictability sieve (which selects states that produce least entropy), purification time (which looks for states that are the easiest to find out from the imprint they leave on the environment), efficiency threshold (which finds states that can be deduced from measurements on a smallest fraction of the environment), and purity loss time (that looks for states for which it takes the longest to lose a set fraction of their initial purity). We show that when pointer states -- the most predictable states of an open quantum system selected by the predictability sieve -- are well defined, all four criteria agree that they are indeed the most classical states. We illustrate this with two examples: an underdamped harmonic oscillator, for which coherent states are unanimously chosen by all criteria, and a free particle undergoing quantum Brownian motion, for which most criteria select almost identical Gaussian states (although, in this case, predictability sieve does not select well defined pointer states.)

description: The present study aims at utilizing field effect phenomenon to induce heterogeneous surface charge and consequently changing the fluid flow in a solid state nanochannel with converging-diverging periodicity. It is shown that the proposed geometry causes non-uniform radial field adjacent to channel walls which is stronger around the diverging section and weaker next to the converging part of the wall. The later generates heterogeneous surface charge at channel walls depending on the applied gate potential i.e. applying low gate potential enables effective modulation of surface charge with the same polarity of the intrinsic charge at channel walls, while moderate gate potential causes charge inversion in diverging sections of the channel and generates reverse flow and thus results in fluid flow circulation. The potential application of flow circulation for trapping and rejection of particles is also demonstrated.

description: The objective of the paper is to examine the changes in the level of diversification of the labour productivity in the European Union countries in the years 1998-2015, and then to determine whether there is any convergence of the labour productivity among these countries. The labour productivity has been calculated as a relation of the gross value added at constant prices per one fulltime employee. The study used the Economic Accounts for Agriculture (EAA) and the Agricultural Labour Input (ALI). The study covered the European Union countries, broken down by the countries of the „old” EU (EU-15) and the countries admitted to the EU after 2004. In order to determine the changes occurring in these countries, sigma-convergence (σ) and beta-convergence (β) have been used. The study shows that after 2011 there was a process of convergence among the EU countries in terms of the labour productivity in agriculture.

description: Advanced composites are used in a variety of industrial applications and therefore attract much scientific interest. Here we describe the formation of novel carbon-based nanocomposites via incorporation of graphene oxide into the crystal lattice of single crystals of calcite. Incorporation of a 2D organic material into single-crystal lattices has never before been reported. To characterize the resulting nanocomposites we employed high-resolution synchrotron powder X-ray diffraction, electron microscopy, transmission electron microscopy, fluorescence microscopy, and nanoindentation tests. Detailed analysis revealed a layered distribution of graphene oxide sheets incorporated within the calcite host. Moreover, the optical and mechanical properties of the calcite host were altered when a carbon-based nanomaterial was introduced into its lattice. Compared to pure calcite, the composite GO-calcite crystals exhibited lower elastic modulus and higher hardness. The results of this study show that the incorporation of a 2D material within a 3D crystal lattice is not only feasible but also can lead to the formation of hybrid crystals exhibiting new properties.
Palatini approach to 1/R gravity and its implications to the late Universe

description: By applying the Palatini approach to the 1/R-gravity model it is possible to explain the present accelerated expansion of the Universe. Investigation of the late Universe limiting case shows that: (i) due to the curvature effects the energy-momentum tensor of the matter field is not covariantly conserved; (ii) however, it is possible to reinterpret the curvature corrections as sources of the gravitational field, by defining a modified energy-momentum tensor; (iii) with the adoption of this modified energy-momentum tensor the Einstein's field equations are recovered with two main modifications: the first one is the weakening of the gravitational effects of matter whereas the second is the emergence of an effective varying "cosmological constant"; (iv) there is a transition in the evolution of the cosmic scale factor from a power-law scaling $a\propto t^{11/18}$ to an asymptotically exponential scaling $a\propto \exp(t)$; (v) the energy density of the matter field scales as $ρ_m\propto (1/a)^{36/11}$; (vi) the present age of the Universe and the decelerated-accelerated transition redshift are smaller than the corresponding ones in the $Λ$CDM model.

description: The influence of array geometry on synchronization properties of a 2-D oscillator array is investigated based on a comparison between a rectangular and a hexagonal grid. The Kuramoto model is solved for a nearest-neighbor case with periodic boundary conditions and for a small-scale, realistic coupling case with 1/r^3 decay characteristic of spintronic oscillators. In both cases, it is found that the hexagonal grid choice leads to lower synchronization threshold and higher emission power than its rectangular counterpart, which results from increased connectivity, as well as, in the realistic-coupling case, from decreased contributions of the array edges. Additionally, a more general spin-torque oscillator model including both amplitude and phase as degrees of freedom is employed for reservoir computing simulations, showing that by using hexagonal grid one can increase the short-term memory capacity but not the parity-check capacity of the system.
Magnetism in the Hubbard model-An improved treatment

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We propose a new treatment of the Hubbard model that is based both on the coherent-potential approximation (CPA) and the virtual-crystal approximation (VCA). It is well known that the equilibrium found using the one-particle CPA Green's functions does not predict an ordered magnetic ground state, while Stoner's mean-field treatment, which is equivalent to the VCA on the Hubbard model, does so for a wide range of parameters. A hybrid treatment, the tau-CPA, is developed, in which a particle is assumed to be scattered from an array of static opposite spins for a time tau related to the inverse of the band width. The propagation is treated in the CPA over this period; thereafter the particle sees the time-averaged effect of the scatterers and hence can be treated in the VCA. This model, with suitable approximations, does predict magnetism for a modified Stoner criterion.

description: We introduce an alternative discretization for static quarks on the lattice retaining the O(a) improvement properties of the Eichten-Hill action. In this formulation, statistical fluctuations are reduced by a factor which grows exponentially with Euclidean time, x_0. For the first time, B-meson correlation functions are computed with good statistical precision in the static approximation for x_0>1 fm. At lattice spacings a \approx 0.1 fm, a \approx 0.08 fm and a \approx 0.07 fm the B_s-meson decay constant is determined in static and quenched approximations. A correction due to the finite mass of the b-quark is estimated by combining these static results with a recent determination of F_Ds.

In the first part of the study a selected food market of France is characterized as a reference point of further analyses and studies. The data was obtained from French domestic reports which cover years 2007-2016. Dynamics of changes has been defined as well as the trends characteristic of the analyzed period. The method of least squares has been used. Moreover, a definition and the importance of clusters has been presented on the basis of the literature of that topic. The part of the study includes a description of functioning of a selected French organic food cluster is described and evaluated. The method of case study has been used. It has been found that in 2007-2016 the eco-sector in France has developed significantly. A distinctly rising linear trend in the number of organic farms, ecological companies, ecologically cultivated land, the size of the market and degree of French people's knowledge of organic food labels has been reported for the eco-branch in France. As many as 112 projects have been implemented in the analyzed cluster. Those projects involved innovative and export undertakings which allowed to achieve a competitive advantage on the domestic market and even abroad. Positive effects also include possibility of experience exchange and financial support particularly important for young entrepreneurs.

description: This paper attempts to rank EU countries according to changes in consumer food preferences between 2001 and 2013. The size of these changes was determined using a synthetic rate created for this purpose. This rate was intended to accommodate changes in consumption levels in 9 product groups per capita. It turns out that we may use the greatest possible measure of the structure’s dissimilarity as an analogy to the Gini coefficient, to express this rate. Using the “ar” measure to compare structures of food consumption in two separate three-year time periods for each country, scientists may rank and group the countries according to the value of changes in consumer food preferences.

description: The use of plastics in agriculture, or plasticulture, is a comparatively recent phenomenon, with numerous associated benefits and is used globally to enhance agricultural production. Despite the production benefits of agricultural plastics, sustainable waste management is a considerable challenge, but an important goal for the UBC farm. The objectives of this project were to determine the primary plastics used in agriculture, to establish the main issues concerning the management of plastic waste, and to identify potential alternatives and solutions regarding these challenges. To fulfill these goals, a thorough literature search was conducted, as well as extensive communication with various people affiliated with the recycling industry. The plastics primarily used at the UBC farm include drip tape, plastic mulch, and greenhouse films. It was determined that there are several waste management alternatives for these plastics that are commonly implemented in agriculture, including biodegradable plastics, incineration, and recycling. Recycling was identified as potentially being the most environmentally sustainable alternative to plastic waste management. However, due to a poor market for recycled products and a general reluctance by the recycling industry to refine agricultural plastics, recycling is not a plausible alternative at this time. More research and an initiation of open communication between the agricultural and recycling sectors is necessary to make recycling feasible for everyone involved.

description: We consider AdS_5 x S^5 string states with several large angular momenta along AdS_5 and S^5 directions which are dual to single-trace Super-Yang-Mills (SYM) operators built out of chiral combinations of scalars and covariant derivatives. In particular, we focus on the SU(3) sector (with three spins in S^5) and the SL(2) sector (with one spin in AdS_5 and one in S^5), generalizing recent work hep-th/0311203 and hep-th/0403120 on the SU(2) sector with two spins in S^5. We show that, in the large spin limit and at the leading order in the effective coupling expansion, the string sigma model equations of motion reduce to matrix Landau-Lifshitz equations. We then demonstrate that the coherent-state expectation value of the one-loop SYM dilatation operator restricted to the corresponding sector of single trace operators is also effectively described by the same equations. This implies a universal leading order equivalence between string energies and SYM anomalous dimensions, as well as a matching of integrable structures. We also discuss the more general 5-spin sector and comment on SO(6) states dual to non-chiral scalar operators.

description: We compare three methods of estimating the duration, or half-life, of advertising using computer simulation experiments. In particular, we investigate how well each method works with the data aggregated over different time intervals. In contrast with the existing theory on the, so called, data interval bias, our experiments are based upon realistic advertising schedules. Our results appear to indicate that the indirect "t-ratio" estimation procedure favoured by practitioners works well in the presence of such temporal aggregation. Additionally, we suggest a transformation that can be used in combination with the indirect "t-ratio" estimation procedure to obtain estimates of the underlying micro-period half-life from a variety of common (macro) data frequencies.

description: A graphene field effect transistor, where the active area is made of monolayer large-area graphene, is simulated including a full 2D Poisson equation and a drift-diffusion model with mobilities deduced by a direct numerical solution of the semiclassical Boltzmann equations for charge transport by a suitable discontinuous Galerkin approach. The critical issue in a graphene field effect transistor is the difficulty of fixing the off state which requires an accurate calibration of the gate voltages. In the present paper we propose and simulate a graphene field effect transistor structure which has well-behaved characteristic curves similar to those of conventional (with gap) semiconductor materials. The introduced device has a clear off region and can be the prototype of devices suited for post-silicon nanoscale electron technology. The specific geometry overcomes the problems of triggering the minority charge current and gives a viable way for the design of electron devices based on large area monolayer graphene as substitute of standard semiconductors in the active area. The good field effect transistor behavior of the current versus the gate voltage makes the simulated device very promising and a challenging case for experimentalists.
On the Approximation of Saddlepoint Expansions in Statistics

description: The exact saddlepoint approximation as developed by Daniels [4], is an extremely accurate method for approximating probability distributions. Recent applications of the technique to densities of statistics of interest have been hindered by the requirement of explicit knowledge of the cumulant generating function, and the need to obtain an analytic solution to the saddlepoint defining equation. In this paper we show the conditions under which any approximation to the saddlepoint is justified, and suggest a solution that does not affect the usual merits of the exact expansion. We illustrate with an approximate saddlepoint expansion of the Durbin-Watson test statistic.

description: Vector leptoquarks can address the lepton flavor universality anomalies in decays associated with the $b \to c \ell ν$ and $b \to s \ell \ell$ transitions, as observed in recent years. Generically, these leptoquarks yield new sources of CP violation. In this paper, we explore constraints and discovery potential for electric dipole moments (EDMs) in leptonic and hadronic systems. We provide the most generic expressions for dipole moments induced by vector leptoquarks at one loop. We find that $O(1)$ CP-violating phases in tau and muon couplings can lead to corresponding EDMs within reach of next-generation EDM experiments, and that existing bounds on the electron EDM already put stringent constraints on CP-violating electron couplings.

description: In analysing the effects of economic policy in a Federal system, such as Australia, it is important to understand the interactions between the States and Territories. In particular, given that there is free movement between labour markets, to analyse economic policy it is important to understand the factors influencing inter-regional migration. In this paper we use data from 1982 to 1996 to estimate a structural econometric model of inter-regional migration. The results are then used to re-specify and calibrate the Computable General Equilibrium model MONASH-MRF. This then provides a more detailed picture of labour market responses when we subsequently simulate the response of net inter-state migration to changes in State Government spending.

description: The first zine in this project was a series of hundred-word reflections (Lauren & Berlandt, 2019) [“four hundreds for me”] I wrote sitting under my desk at 7am in the middle of winter, underneath my a/r/tographic playmat. Somewhat compulsively, I wrote zine after zine as a sense-making exercise (Greene, 1987; Haynes, 2001), initially to examine my inability to participate in my own research. The turn occurs when I see these zines as a/r/tographic openings (Irwin, 2013) for and as research.
These zines unfolded to story reasons why I could not participate in my own research, including being tired [“four hundreds for me”], being overwhelmed [“how to do dishes”], discomfort around being a working mother [“Re/searching, art/making, m/othering”] and the feeling of drowning [“What Are You Doing in Gloomy Hollow?”]. I explored my inability to participate in a living inquiry that felt haunted by postpartum psychosis and the unravelling of significant childhood trauma [“eeexxxccceessss” and “[sur]renderings: contiguity and living inquiry”]. I folded a longtime friend into the process [“how to make a zine when your life is falling apart”] and started to see the boundaries between my personal zine-making and the zines made as da/r/ta by participants shift; they started to overlap. I started to see their grief for their schools mirrored in my own grief for my research [“an ode to our goals for education (or something”] and my drowning in motherhood as contiguous with their drowning in schools [“neither of these wolves can do it”].This is an 8-page zine where I return to an earlier written reflection where I wrote about my painting teacher saying, ‘when you don’t know what to paint, do the dishes’. I employ the artificial intelligence Goblintools.ai to instruct me on how to do dishes.

description: Comparison of theoretical line profiles to observations provides important tests for supernova explosion models. We study the shapes of radioactive decay lines predicted by current 3D core-collapse explosion simulations, and compare these to observations of SN 1987A and Cas A. Both the widths and shifts of decay lines vary by several thousand kilometers per second depending on viewing angle. The line profiles can be complex with multiple peaks. By combining observational constraints from 56Co decay lines, 44Ti decay lines, and Fe IR lines, we delineate a picture of the morphology of the explosive burning ashes in SN 1987A. For M_ZAMS=15-20 Msun progenitors exploding with ~1.5 *10^51 erg, ejecta structures suitable to reproduce the observations involve a bulk asymmetry of the 56Ni of at least ~400 km/s and a bulk velocity of at least ~1500 km/s. By adding constraints to reproduce the UVOIR bolometric light curve of SN 1987A up to 600d, an ejecta mass around 14 Msun is favoured. We also investigate whether observed decay lines can constrain the neutron star (NS) kick velocity. The model grid provides a constraint V_NS > V_redshift, and applying this to SN 1987A gives a NS kick of at least 500 km/s. For Cas A, our single model provides a satisfactory fit to the NuSTAR observations and reinforces the result that current neutrino-driven core-collapse SN models can achieve enough bulk asymmetry in the explosive burning material. Finally, we investigate the internal gamma-ray field and energy deposition, and compare the 3D models to 1D approximations.

title: An analysis of the structure and determinants of Turkey-EU trade
Creators: name: Kosekahyaoglu, Levent

description: The aim of this thesis is to examine the structure and determinants of TurkevEU trade at both aggregate and sectorally disaggregated levels after the trade liberalisation and restructuring program of Turkey in the 1980s in order to assess the possible effects of further trade liberalisation between Turkey and the EU (le Turkey's accession to the EU). Before studying the determinants of Turkey-EU trade, we first investigate the competitiveness of Turkish manufacturing relative to the EU over the liberalisation period using Balassa's revealed competitive advantage (RCA) indices as well as the similarity of exports from Turkey and the EU using Finger and Kreinin similarity indices. Our analysis on the similarity of exports includes comparison of the similarity of exports from Turkey and the three Mediterranean countries, namely Spain, Greece and Portugal which have similar factor endowments. Regarding the overall similarity of exports from Turkey and the EU as a whole, we find that the similarity of exports from the two areas has increased noticeably over the liberalisation period when there was a shift in commodity composition of Turkey's exports towards manufactured goods. Our results suggest that the assessment of the similarity of exports from Turkey and the three Mediterranean countries should consider the type of the products as the similarity of exports in agricultural goods differs substantially from that of manufactured goods. Our results on determinants of Turkey-EU trade indicate that wages appear to be a key factor in explaining Turkey's exports to the EU not only for loww -tech industries, but also for medium and high-tech industries. This suggests that the remarkable increase in Turkey's exports in the 1980s relied heavily on low wage levels which not only increased the cost competitiveness of the country but also reduced domestic demand and hence forced firms to exploit foreign markets. In conclusion, our results indicate that the structural adjustment and trade liberalisation reforms of Turkey in the early 1980s have brought the Turkish economy closer to the EU and put Turkey's economy on the right track for integration with the EU or Europe at large, notwithstanding the huge problems that have emerged.

description: Statistics is commonly taught as a set of techniques to aid in decision making, by extracting information from data. It is argued here that the underlying purpose, often implicit rather than explicit, of every statistical analysis is to establish a set of probability models which can be used to predict values of one or more variables. Such a model constitutes 'information' only in the sense, and to the extent, that it provides predictions of sufficient quality to be useful for decision making. The quality of the decision making is determined by the quality of the predictions, and hence by that of the models used. Using natural criteria, the 'best predictions' for nominal and numeric variables are respectively the mode and mean. For a nominal variable, the quality of a prediction is measured by the probability of error; for a numeric variable, it is specified using a prediction interval. Presenting statistical analysis in this way provides students with a clearer understanding of what a statistical analysis is, and its role in decision making'.
