description: This paper aims to clarify the direction of change in rural employment on short- and medium term in Romania, while CAP regulations are being introduced and the global economic crisis emerges. First we put into evidence the decrease of the role of agriculture as buffer for unemployment and the poor contribution of non-agricultural activities to provide employment for rural residents. Then we analyse the main characteristics of the rural labour force. Finally we synthesize the opinions expressed by 33 consultants (working at the Offices for Agricultural Consultancy from different counties in Transylvania) about the estimated short term evolution of rural employment and the impact of CAP on Romanian rural areas.

description: A two dimensional lattice gas model with ''core-softened'' potential is investigated. Two liquid phases and density anomaly are found. The demixing phase transition between the two liquid phases end at a tricritical point that is also the terminus of a critical line. The density anomaly is related to this continuous line.
Gender equality : panacea or placebo? : third world, anti-racist feminist critiques of the Canadian International Development Agency’s gender equality policy and policymaking process
Creators: name: Zavis, Cathy J.
Publisher: name: University of British Columbia
Year: 2009

description: In response to concerns raised by Northern and Southern feminists that development agencies neglected Third World women's needs, development agencies began in the 1970s to implement policies and projects geared toward women. These have taken various forms over the years. Most recently, international aid agencies have instituted gender equality policies. Despite these interventions, Third World women are still struggling to survive. In this thesis, I explore why this is the case: to what extent can gender equality policies crafted in the First World address the inequalities in the Third World? To explore this question, I look at the participatory policymaking process the Canadian International Development Agency (CIDA) used in 1998 to update its gender equity policy, and the resulting policy. In its effort to ensure that its policymaking process was broad based, open, transparent and inclusive, CIDA chose the Internet as its medium. By looking at CIDA's process and policy, I can begin to understand how systems are put together and the consequences of that configuration and outcome. I am using the local situation "as an entry point to the study of institutional and discursive forces and how these are related to larger socio-economic processes" (Escobar 1995, 109). My examination demonstrates that CIDA's process was, in fact, a ritualistic exercise. The voices of Third World grassroots women, the very women the policy is intended to benefit, were excluded, while individuals in institutions of ruling were explicitly included. By managing and controlling all aspects of the consultation to ensure the outcome it desired, staff co-opted feminist strategic goals to meet the agency's bureaucratic needs. Through this cursory participatory process, gender staff at CIDA exercised their power over Third World women, thereby maintaining their status. CIDA's gender equality policymaking process and policy are illustrative of how international development institutions whether wittingly or not perpetuate the racialization of Third World women. By doing so, they are (as Razack explains in the context of refugee hearings) "inevitably an encounter between the white First World and the racialized Third World" (1999, 89).

description: We report on the evaporation of hexane from porous alumina and silicon membranes. These membranes contain billions of independent nanopores tailored to an ink-bottle shape, where a cavity several tens of nanometers in diameter is separated from the bulk vapor by a constriction. For alumina membranes with narrow enough constrictions, we demonstrate that cavity evaporation proceeds by cavitation. Measurements of the pressure dependence of the cavitation rate follow the predictions of the bulk, homogeneous, classical nucleation theory, definitively establishing the relevance of homogeneous cavitation as an evaporation mechanism in mesoporous materials. Our results imply that porous alumina membranes are a promising new system to study liquids in a deeply metastable state.

description: Cell-based neutralization assays are of central importance for the development of new vaccine candidates as well as quality assurance of already approved vaccines. Suppression of viral infection by neutralizing antibodies present in serum of vaccinated individuals serves as an indicator for efficacy of a vaccine. Established readouts used to date are hardly automated, provide no time resolution and require expensive reagents. These shortcomings are limiting factors in vaccine development. In contrast, when virus-compatible host cells are grown on multi-electrode arrays, the cellular infection state and the associated cell response are assessable by impedance measurements. Unlike endpoint assays, the host cell response is followed continuously in real time, label-free and noninvasively. Here, a sensor platform comprising hardware, software and disposable electrode arrays is described suitable for fully automated cell-based neutralization assays tailored for high throughput screening campaigns. To develop cost-effective, disposable electrode arrays for impedance measurements, we screen printed film electrodes made from conducting polymers on the bottom of multi-well plates. The polymer electrodes were characterized for their host cell compatibility and readout performance in comparison to established gold-film electrodes. Hard- and software were tailored for robust and routine use in virological assays. Virus titration, virus neutralization as well as antiviral drug (Efavirenz) intervention studies were conducted using vesicular stomatitis virus (VSV) pseudotypes or the Env HIV-1 infectious molecular clones Ce1176 and X1632 as viral model systems. The assays showed very similar analytical performance in terms of titration curves and dose–response relationships for polymer electrodes compared to commercial gold-film electrode arrays and reporter-based endpoint assays. Considering their technical advantages over established assays, impedance readings based on low-cost polymer electrode arrays may become an attractive alternative to conventional assays using luminescent or colorimetric readouts.

description: Short channel (~80 nm) n-type single-walled carbon nanotube (SWNT) field-effect transistors (FETs) with potassium (K) doped source and drain regions and high-k gate dielectrics (ALD HfO2) are obtained. For nanotubes with diameter ~ 1.6 nm and bandgap ~ 0.55 eV, we obtain n-MOSFET-like devices exhibiting high on-currents due to chemically suppressed Schottky barriers at the contacts, subthreshold swing of 70mV/decade, negligible ambipolar conduction and high on/off ratios up to 10^6 at a bias voltage of 0.5V. The results compare favorably with the state-of-the-art silicon n-MOSFETs and demonstrate the potential of SWNTs for future complementary electronics. The effects of doping level on the electrical characteristics of the nanotube devices are discussed.

description: The principle of the regional concentration – as one of the important means of regional competitiveness – and the cooperations being organised more consciously have big parts in the development and operation of the tourist destination management. The principle of complexity is emphasised differently that means, on the one hand, the more effective use of the connection possibilities of tourism to other branches, on the other hand, it takes for granted the development of the background infrastructure supporting tourism more intensively beside the development of the tourist infrastructure. The basic principle of the competitive developments are the sustainable developments and the innovative approach. Tourist destination can be identified with the tourist supply (product) from the elements of the tourist system: the tourist supply and the tourist destination are consisting just of the same elements. The difference is that the tourist product can be only one product and destination can be characterised as a complex pile of attractions and services being in connection with each other. The cooperation of the characters of destination are organised by the tourist value chain of which elements are the experiences in connection with the formation of the image, preparation of travel, travel, destination, return from the point of view of the tourist and the service providers of destination. Services of different level provided by the suppliers can influence the opinion and experience of the tourist in connection with destination negatively. The independent destination management system with suitable competence and specialists, running a coordinating activity can make a connection between the tourist and the receiving area.

description: The purpose of this paper is to provide an understanding of corporate risk management practices in Romanian companies, by investigating the risk management approaches Romanian companies take. Our main findings are that Romanian managers are not aware of the magnitude of exposure their companies have to various types of risk – hazard, operational, financial and strategic risks, while they are able to manage rather well all these risks, even the ones that have the lowest impact on the business. At the same time, risk management systems employed by Romanian companies are rather inarticulate and based on traditional approaches towards risk management, which might represent by itself a major source of risk, given the complexity of the business environment they face.

description: Automatic differentiation, as implemented today, does not have a simple mathematical model adapted to the needs of modern machine learning. In this work we articulate the relationships between differentiation of programs as implemented in practice and differentiation of nonsmooth functions. To this end we provide a simple class of functions, a nonsmooth calculus, and show how they apply to stochastic approximation methods. We also evidence the issue of artificial critical points created by algorithmic differentiation and show how usual methods avoid these points with probability one.

description: We study the effects of generic short-ranged interactions on a system of 2D Dirac fermions subject to a special kind of static disorder, often referred to as ``chiral.'' The non-interacting system is a member of the disorder class BDI [M. R. Zirnbauer, J. Math. Phys. 37, 4986 (1996)]. It emerges, for example, as a low-energy description of a time-reversal invariant tight-binding model of spinless fermions on a honeycomb lattice, subject to random hopping, and possessing particle-hole symmetry. It is known that, in the absence of interactions, this disordered system is special in that it does not localize in 2D, but possesses extended states and a finite conductivity at zero energy, as well as a strongly divergent low-energy density of states. In the context of the hopping model, the short-range interactions that we consider are particle-hole symmetric density-density interactions. Using a perturbative one-loop renormalization group analysis, we show that the same mechanism responsible for the divergence of the density of states in the non-interacting system leads to an instability, in which the interactions are driven strongly relevant by the disorder. This result should be contrasted with the limit of clean Dirac fermions in 2D, which is stable against the inclusion of weak short-ranged interactions. Our work suggests a novel mechanism wherein a clean system, initially insensitive to interaction effects, can be made unstable to interactions upon the inclusion of weak static disorder.

Contrary to a recent prediction (I. Eremin, {\it et al.}, Phys. Rev. B {\bf 69}, 094517 (2004)), a negligible shift (at best $\leq$ +0.2 meV) of the resonance energy is observed upon oxygen isotope substitution ($^{16}$O$\to^{18}$O). This suggests a negligible spin-phonon interaction in the high-$T_c$ cuprates at optimal doping.

description: A highly anticipated application for quantum computers is as a universal simulator of quantum many-body systems, as was conjectured by Richard Feynman in the 1980s. The last decade has witnessed the growing success of quantum computing for simulating static properties of quantum systems, i.e., the ground state energy of small molecules. However, it remains a challenge to simulate quantum many-body dynamics on current-to-near-future noisy intermediate-scale quantum computers. Here, we demonstrate successful simulation of nontrivial quantum dynamics on IBM's Q16 Melbourne quantum processor and Rigetti's Aspen quantum processor; namely, ultrafast control of emergent magnetism by THz radiation in an atomically-thin two-dimensional material. The full code and step-by-step tutorials for performing such simulations are included to lower the barrier to access for future research on these two quantum computers. As such, this work lays a foundation for the promising study of a wide variety of quantum dynamics on near-future quantum computers, including dynamic localization of Floquet states and topological protection of qubits in noisy environments.

My empirical analysis is based on data containing 192 agricultural enterprises between 2002 and 2006. I try to assess the reasons of the changes in the structure of resources of enterprises in order to find the determinants effecting the capital structure. Furthermore, I assess the index numbers illustrating the management of the enterprises.

In this paper, we report our experimental study of an angular-momentum-dominated beam produced in a photoinjector, addressing the dependencies of angular momentum on initial conditions. We also briefly discuss the removal of angular momentum. The results of the experiment, carried out at the Fermilab/NICADD Photoinjector Laboratory, are found to be in good agreement with theoretical and numerical models.

description: The question of sustainability of agricultural production especially animal production and events leading to its development can be dated back to the second part of the last century. Sustainability is a priority subject matter as it is a core element in our existence and in the survival of the forthcoming generations. The notion of sustainability comprises three aspects: ecological, social and political and economic target systems, which by now have been supplemented with cultural and regional elements including the protection of environment, local traditions, scale of values, cultural and historical heritage. The principles of sustainable development also include the improvement of human and animal health and the maintenance of vital rural communities. The priority notion of sustainability of agricultural production refers also to animal husbandry and especially sheep production. Sheep have contributed substantially to the grassland-based agricultural production in Hungary for centuries. Sheep sector is important in rural areas as the tool of sustainability of animal production. It should also be highlighted that contrary to numerous efforts, the globally difficult process of sustainable development poses almost unsolvable problems for implementers even on local and regional levels. This paper will review briefly the levels of sustainability in the Hungarian animal production with a special regard to sheep production and their content and then points out the most significant economic issues by the application of “SWOT” – analysis, “problem tree’ and “structure of objectives” methods, on the grounds of the received findings.

description: The role of the time factor in management is increasing. Change directs attention to the time factor from the point of view of the organisation, and management does the same from that of the person. I examined the time management practice of managers of organisations related to agribusiness, and the reaction time characterising the adaption ability of the organisations through a questionnaire survey. I analysed the collected data with scientifically established statistical methods. During studying resources, managing tasks, change, reaction time and effect I explored the features of time as resource, the significance of the time factor, the improvability of time efficiency in the different managing functions, the factors supporting and hindering the quick reaction of organisations, and what rearrangements can be seen in management work nowadays.
Dirac Quantization of the Pais-Uhlenbeck Fourth Order Oscillator

description: As a model, the Pais-Uhlenbeck fourth order oscillator with equation of motion $d^4q/dt^4+(ω_1^2+ω_2^2)d^2q/dt^2 +ω_1^2ω_2^2 q=0$ is a quantum-mechanical prototype of a field theory containing both second and fourth order derivative terms. With its dynamical degrees of freedom obeying constraints due to the presence of higher order time derivatives, the model cannot be quantized canonically. We thus quantize it using the method of Dirac constraints to construct the correct quantum-mechanical Hamiltonian for the system, and find that the Hamiltonian diagonalizes in the positive and negative norm states that are characteristic of higher derivative field theories. However, we also find that the oscillator commutation relations become singular in the $ω_1 \to ω_2$ limit, a limit which corresponds to a prototype of a pure fourth order theory. Thus the particle content of the $ω_1 =ω_2$ theory cannot be inferred from that of the $ω_1 \neq ω_2$ theory; and in fact in the $ω_1 \to ω_2$ limit we find that all of the $ω_1 \neq ω_2$ negative norm states move off shell, with the spectrum of asymptotic in and out states of the equal frequency theory being found to be completely devoid of states with either negative energy or negative norm. As a byproduct of our work we find a Pais-Uhlenbeck analog of the zero energy theorem of Boulware, Horowitz and Strominger, and show how in the equal frequency Pais-Uhlenbeck theory the theorem can be transformed into a positive energy theorem instead.

description: The most important aim of authors’ study is to get to know the Hungarian pork consumption in our days. Our aim is set to estimate pork meat consumption and purchasing habits of consumers who are living in Eastern part of Hungary. The pork section is influenced negatively by several factors nowadays, which have a clear effect on the pork consumption and cause its declination. During the research work a questionnaire survey was made in 2007 and 2008. 1089 persons in different locations of Eastern Hungary were altogether asked. The data were evaluated by statistic hypothesis testing. Based on the evaluation a clear picture was got about the consumers’ purchasing and consuming habits, and their ideas, opinions about the Hungarian pork as a food and as an item wearing a kind of national behaviour. Through many questions the volume of consumption was explored, and the pork’s proportion was compared to the rest of other meat types. It is verifiable that the pork consumption can be handled as a national habit, which is not the same by different age groups and educational qualifications. The importance of some factors during purchasing was also examined. Exceptionally important factors are: quality, the appearance, the origin and the price, that were mostly considered by the customers. The effect of pork promotion advertisements and its evaluation by the customers were surveyed too, which in connection with the efficiency showed a fairly stable picture both in 2007 and in 2008. The examination of price elasticity showed that this figure is influenced not just by the product group itself, but the purchasing power of the costumers, as well.

description: We propose a novel, canopy density estimation solution using a 3D ray cloud representation for perennial horticultural crops at the field scale. To attain high spatial and temporal fidelity in field conditions, we propose the application of continuous-time 3D SLAM (Simultaneous Localisation and Mapping) to a spinning lidar payload (AgScan3D) mounted on a moving farm vehicle. The AgScan3D data is processed through a Continuous-Time SLAM algorithm into a globally registered 3D ray cloud. The global ray cloud is a canonical data format (a digital twin) from which we can compare vineyard snapshots over multiple times within a season and across seasons. Then, the vineyard rows are automatically extracted from the ray cloud and a novel density calculation is performed to estimate the maximum likelihood canopy densities of the vineyard. This combination of digital twinning, together with the accurate extraction of canopy structure information, allows entire vineyards to be analysed and compared, across the growing season and from year to year. The proposed method is evaluated both in simulation and field experiments. Field experiments were performed at four sites, which varied in vineyard structure and vine management, over two growing seasons and 64 data collection campaigns, resulting in a total traversal of 160 kilometres, 42.4 scanned hectares of vines with a combined total of approximately 93,000 scanned vines. Our experiments show canopy density repeatability of 3.8% (Relative RMSE) per vineyard panel, for acquisition speeds of 5-6 km/h, and under half the standard deviation in estimated densities when compared to an industry standard gap-fraction based solution. The code and field datasets are available at https://github.com/csiro-robotics/agscan3d.

description: Spontaneous emission of a photon by an atom is described theoretically in three dimensions with the initial wave function of a finite-mass atom taken in the form of a finite-size wave packet. Recoil and wave-packet spreading are taken into account. The total atom-photon wave function is found in the momentum and coordinate representations as the solution of an initial-value problem. The atom-photon entanglement arising in such a process is shown to be closely related to the structure of atom and photon wave packets which can be measured in the coincidence and single-particle schemes of measurements. Two predicted effects, arising under the conditions of high entanglement, are anomalous narrowing of the coincidence wave packets and, under different conditions, anomalous broadening of the single-particle wave packets. Fundamental symmetry relations between the photon and atom single-particle and coincidence wave packet widths are established. The relationship with the famous scenario of Einstein-Podolsky-Rosen is discussed.

description: It is well accepted that emergency food transfers are required to meet the food needs of affected populations during acute, short-run emergencies. It is also widely acknowledged that growing incomes and well functioning markets are necessary to facilitate access to food by vulnerable groups over the long run. What is less appreciated is that market-based strategies can be used to a) directly address short-run emergencies, and b) reduce the severity of short and long-run emergencies. The purpose of this short paper is to call attention to research findings that provide important guidelines for how this can be done.

description: A new mechanism (DeltaC1-DeltaC3 coupling) is accounted for the spin splitting of wurtzite GaN, which is originated from the intrinsic wurtzite effects (band folding and structure inversion asymmetry). The band-folding effect generates two conduction bands (DeltaC1 and DeltaC3), in which p-wave probability has tremendous change when kz approaches anti-crossing zone. The spin-splitting energy induced by the DeltaC1-DeltaC3 coupling and wurtzite structure inversion asymmetry is much larger than that evaluated by traditional Rashba or Dresselhaus effects. When we apply the coupling to GaN/AlN quantum wells, we find that the spin-splitting energy is sensitively controllable by an electric field. Based on the mechanism, we proposed a p-wave-enhanced spin-polarized field effect transistor, made of InxGa1-xN/InyAl1-yN, for spintronics application.

description: Bidirectional conversion of electrical and optical signals lies at the foundation of the global internet. Such converters are employed at repeater stations to extend the reach of long-haul fiber optic communication systems and within data centers to exchange high-speed optical signals between computers. Likewise, coherent microwave-to-optical conversion of single photons would enable the exchange of quantum states between remotely connected superconducting quantum processors, a promising quantum computing hardware platform. Despite the prospects of quantum networking, maintaining the fragile quantum state in such a conversion process with superconducting qubits has remained elusive. Here we demonstrate the conversion of a microwave-frequency excitation of a superconducting transmon qubit into an optical photon. We achieve this using an intermediary nanomechanical resonator which converts the electrical excitation of the qubit into a single phonon by means of a piezoelectric interaction, and subsequently converts the phonon to an optical photon via radiation pressure. We demonstrate optical photon generation from the qubit with a signal-to-noise greater than unity by recording quantum Rabi oscillations of the qubit through single-photon detection of the emitted light over an optical fiber. With proposed improvements in the device and external measurement set-up, such quantum transducers may lead to practical devices capable of realizing new hybrid quantum networks, and ultimately, distributed quantum computers.

description: The profitability of various investment styles in investment funds depends on macroeconomic conditions. Market ecology, which views financial markets as ecosystems of diverse, interacting and evolving trading strategies, has shown that endogenous interactions between strategies determine market behaviour and styles' performance. We present Evology: a heterogeneous, empirically calibrated multi-agent market ecology agent-based model to quantify endogenous interactions between US equity mutual funds, particularly Value and Growth investment styles. We outline the model design, validation and calibration approach and its potential for optimising investment strategies using machine learning algorithms.

description: We investigate the electronic structure and the hole content in the copper-oxygen planes of Hg based high Tc cuprates for one to four CuO2 layers and hydrostatic pressures up to 15 GPa. We find that with the pressure-induced additional number of holes of the order of 0.05e the density of states at the Fermi level changes approximately by a factor of 2. At the same time the saddle point is moved to the Fermi level accompanied by an enhanced k_z dispersion. This finding explains the pressure behavior of Tc and leads to the conclusion that the applicability of the van Hove scenario is restricted. By comparison with experiment, we estimate the coupling constant to be of the order of 1, ruling out the weak coupling limit.

Analytical approximation for $< ϕ^2 >$ of a quantized scalar field in ultrastatic asymptotically flat spacetimes

description: Analytical approximations for $< ϕ^2 >$ of a quantized scalar field in ultrastatic asymptotically flat spacetimes are obtained. The field is assumed to be both massive and massless, with an arbitrary coupling $ξ$ to the scalar curvature, and in a zero or nonzero temperature vacuum state. The expression for $< ϕ^2 >$ is divided into low- and high-frequency parts. The expansion for the high-frequency contribution to this quantity is obtained. This expansion is analogous to the DeWitt-Schwinger one. As an example, the low-frequency contribution to $< ϕ^2 >$ is calculated on the background of the small perturbed flat spacetime in a quantum state corresponding to the Minkowski vacuum at the asymptotic. The limits of the applicability of these approximations are discussed.

description: Understanding the principle of information flow across distributed brain networks is of paramount importance in neuroscience. Here, we introduce a novel neuroimaging framework, leveraging integrated effective connectivity (iEC) and unconstrained signal flow mapping for data-driven discovery of the human cerebral functional hierarchy. Simulation and empirical validation demonstrated the high fidelity of iEC in recovering connectome directionality and its potential relationship with histologically defined feedforward and feedback pathways. Notably, the iEC-derived hierarchy displayed a monotonously increasing level along the axis where the sensorimotor, association, and paralimbic areas are sequentially ordered – a pattern supported by the Structural Model of laminar connectivity. This hierarchy was further demonstrated to flexibly reorganize according to brain states, flattening during an externally oriented condition, evidenced by a reduced slope in the hierarchy, and steepening during an internally focused condition, reflecting heightened engagement of interoceptive regions. Our study highlights the unique role of macroscale directed functional connectivity in uncovering a neurobiologically grounded, state-dependent signal flow hierarchy.

description: Modern computing systems are embracing hybrid memory comprising of DRAM and non-volatile memory (NVM) to combine the best properties of both memory technologies, achieving low latency, high reliability, and high density. A prominent characteristic of DRAM-NVM hybrid memory is that it has NVM access latency much higher than DRAM access latency. We call this inter-memory asymmetry. We observe that parasitic components on a long bitline are a major source of high latency in both DRAM and NVM, and a significant factor contributing to high-voltage operations in NVM, which impact their reliability. We propose an architectural change, where each long bitline in DRAM and NVM is split into two segments by an isolation transistor. One segment can be accessed with lower latency and operating voltage than the other. By introducing tiers, we enable non-uniform accesses within each memory type (which we call intra-memory asymmetry), leading to performance and reliability trade-offs in DRAM-NVM hybrid memory. We extend existing NVM-DRAM OS in three ways. First, we exploit both inter- and intra-memory asymmetries to allocate and migrate memory pages between the tiers in DRAM and NVM. Second, we improve the OS's page allocation decisions by predicting the access intensity of a newly-referenced memory page in a program and placing it to a matching tier during its initial allocation. This minimizes page migrations during program execution, lowering the performance overhead. Third, we propose a solution to migrate pages between the tiers of the same memory without transferring data over the memory channel, minimizing channel occupancy and improving performance. Our overall approach, which we call MNEME, to enable and exploit asymmetries in DRAM-NVM hybrid tiered memory improves both performance and reliability for both single-core and multi-programmed workloads.
