description: This study finds that distillers dried grains with solubles (DDGS) is a dominant feed ingredient in hog finishing rations, despite variability in the product’s nutritional content. The optimal inclusion rate has remained at the maximum allowable limit of 20%, suggesting that when a particular DDGS product has low nutrient content, feed compounders simply supplement with corn and soymeal, whatever deficits in nutrients are created as a result. The study examines DDGS products from 40 different ethanol plants and finds that, relative to the DDGS product with the lowest feed ration cost, the optimal feed ration costs of DDGS products from the other 39 ethanol plants are $0.002 to $0.42 more per cwt of feed. The implied price discount from this cost differential ranges from a low of 0.10% to a high of 25.55%. For an ethanol plant with 50 million gallons in capacity, this price discount amounts to revenue losses of $0.03 million to $6.27 million per year. The study also found that feed compounders generate $7.51 per ton more in DDGS feed cost savings when they eliminate inter-plant variability and face only intra-plant sources of variability. By including nutritional content variability information in the pricing of DDGS, proper price signals are communicated to ethanol plants so that they can make their own assessments on quality control initiatives to reduce variability in their DDGS products. When the market does not reward better DDGS quality or penalize low product quality, stakeholders do not have any incentive to improve product quality.

Mobility in immersed granular materials upon cyclic loading

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We study the mobility of objects embedded in an immersed granular packing and subjected to cyclic loadings. In this aim, we conducted experiments using glass beads immersed in water and a horizontal plate subjected to a cyclic uplift force. Tests performed at different cyclic force frequencies and amplitudes evidence the development of three mobility regimes whereby the plate stays virtually immobile, moves up steadily or slowly creeps upwards. Results show that steady plate uplift can occur at lower force magnitudes when the frequency is increased. We propose an interpretation of this frequency-weakening behaviour based on force relaxation experiments and on the analysis of the mobility response of theoretical visco-elasto-plastic mechanical analogue. These results and analysis point out inherent differences in mobility response between steady and cyclic loadings in immersed granular materials.

description: The familiar injunction to "love thy neighbor as thyself" (Matthew 22: 37-39) has received little sustained philosophical or psychological attention. Our project will answer three key questions: What is love of neighbor? How does it differ from other, related constructs, such as altruism, volunteerism, and other forms of prosocial behavior? Can a scale be developed to measure love of neighbor? We will carry out conceptual, qualitative, and quantitative analyses to answer these questions. Ongoing collaborations between team members will be used to refine the concept of neighborly love and to inform empirical research that will result in the development of a scale, the efficacy of which we will test with a series of experiments. Our project is needed because we believe neighborly love has the potential to bridge divides and thus to ameliorate societal polarization. We will publish the scale, 21 articles, edit a special journal issue and a volume with Routledge Press, produce a website, blog, and podcast series, give 13 conference presentations, and possibly host an online conference and edit an associated volume. Our project will set the stage for a subsequent project that will design and test interventions to promote neighborly love in various settings.

description: Magnetoseismology, a technique of magnetic field diagnostics based on observations of magnetohydrodynamic (MHD) waves, has been widely used to estimate the field strengths of oscillating structures in the solar corona. However, previously magnetoseismology was mostly applied to occasionally occurring oscillation events, providing an estimate of only the average field strength or one-dimensional distribution of field strength along an oscillating structure. This restriction could be eliminated if we apply magnetoseismology to the pervasive propagating transverse MHD waves discovered with the Coronal Multi-channel Polarimeter (CoMP). Using several CoMP observations of the Fe xiii 1074.7 nm and 1079.8 nm spectral lines, we obtained maps of the plasma density and wave phase speed in the corona, which allow us to map both the strength and direction of the coronal magnetic field in the plane of sky. We also examined distributions of the electron density and magnetic field strength, and compared their variations with height in the quiet Sun and active regions. Such measurements could provide critical information to advance our understanding of the Sun's magnetism and the magnetic coupling of the whole solar atmosphere.

description: Given a curve of genus 3 with an unramified double cover, we give an explicit description of the associated Prym-variety. We also describe how an unramified double cover of a non-hyperelliptic genus 3 curve can be mapped into the Jacobian of a curve of genus 2 over its field of definition and how this can be used to do Chabauty- and Brauer-Manin type calculations for curves of genus 5 with an unramified involution. As an application, we determine the rational points on a smooth plane quartic with no particular geometric properties and give examples of curves of genus 3 and 5 violating the Hasse-principle. We also show how these constructions can be used to design smooth plane quartics with specific arithmetic properties. As an example, we give a smooth plane quartic with all 28 bitangents defined over Q(t).

description: We consider a novel system of two-component atomic Bose-Einstein condensate in a double-well potential. Based on the well-known two-mode approximation, we demonstrate that there are obvious avoided level-crossings when both interspecies and intraspecies interactions of two species are increased. The quantum dynamics of the system exhibits revised oscillating behaviors compared with a single component condensate. We also examine the entanglement of two species. Our numerical calculations show the onset of entanglement can be signed as a violation of Cauchy-Schwarz inequality of second-order cross correlation function. Consequently, we use Von Neumann entropy to quantity the degree of entanglement.

description: Over the last few decades scholars have drawn on art-based methodological approaches to study different health outcomes (McNiff 2008, 2012). Previous studies have shown that art-based methodologies embody an effective way to study individuals’ experiences and emotions (i.e., Water et al. 2017). While art-based methodologies have been implemented in several areas of health research, scholars of Alzheimer’s and dementia have made relevant contributions to the study of several aspects of the relationship between art and its benefits for the understanding of patients’ experiences, emotions, as well as the improvement of their life conditions and care (see Beard 2012).

Due to its close connection with linguistic and cognitive skills, poetry has been utilized by researchers as a vehicle for understanding ADRD patients’ lived experience (Swinnen 2016 Swinnen and de Medeiros 2018; Camic 2022; Clark-McGhee). Also, poetry-based interventions have benefited medical students and other healthcare providers in understanding ADRD patients’ experiences and emotions, and in doing so, providing better patient care (Garrie, Goel, and Forsberg 2016).
THE ABROGATION OF SET ASIDE AND THE INCREASE OF CEREAL PRICES: CAN THEY REVERT THE DECLINE OF CEREAL PRODUCTION GENERATED BY DECOUPLING?

description: The decoupling of direct payments, caused by the introduction of the Single Payment Scheme (SPS), has generated an incentive for farmers to decrease the production of cereals, oilseeds and protein crops (COP) and (because of the reform of sugar CMO) sugar beet. In some cases, this has also provided a strong enough incentive for farmers to let some of the available land uncultivated in the years immediately following the introduction of the SPS. However, in the last few years, cereal prices have sharply increased under the pressure of a growing world demand. Under this situation, the EU Commission has abrogated the set aside requirement allowing the cultivation on idle land. In this way the Commission intends to allow EU farmers to take advantage of the new market conditions and to stabilise cereal market. This paper aims at assessing how much the abrogation of set aside requirement can be effective in increasing cereal production. This is not a trivial question given that in some farms the introduction of SPS has also resulted in some of the land previously cultivated (i.e. not set aside) to be left uncultivated. Under this circumstance, the set aside constraint could be not binding and, therefore, its abrogation may not result in an increase of production. The second aim of the paper is to evaluate to what extent increases of cereal prices could foster cereal production and reduce the amount of uncultivated land. The analysis has been carried out on a sample of FADN farms of three study areas located in two regions of Italy (Emilia Romagna and Veneto) using Positive Mathematical Programming (PMP) models. The analysis has shown that the decoupling of direct payments generates a not negligible decrease of COP production and pushes some farmers to let a limited amount of land uncultivated. Therefore, the abrogation of set aside requirement per-se increases cereal production, but this increase is not in all cases very relevant. The increases of cereal prices could be more effective than the abrogation of set aside requirement in increasing cereal production. The combination of both considered factors is expected to revert the decline of cereal production experienced in the considered farms after the introduction of the SPS even if the magnitude of this effect is strongly affected by the level of cereal prices.

description: In this review paper we stress the importance of the higher transcendental Wright functions of the second kind in the framework of Mathematical Physics.We first start with the analytical properties of the classical Wright functions of which we distinguish two kinds. We then justify the relevance of the Wright functions of the second kind as fundamental solutions of the time-fractional diffusion-wave equations. Indeed, we think that this approach is the most accessible point of view for describing non-Gaussian stochastic processes and the transition from sub-diffusion processes to wave propagation. Through the sections of the text and suitable appendices we plan to address the reader in this pathway towards the applications of the Wright functions of the second kind.

description: Blazars are radio-loud Active Galactic Nuclei (AGN) with relativistic jets oriented towards the observer's line-of-sight. Based on their optical spectra, blazars may be classified as flat-spectrum radio quasars (FSRQs) or BL Lacs. FSRQs are more luminous blazars with both narrow and broad emission and absorption lines, while BL Lacs are less luminous and featureless. Recent studies show that blazars dominate (93%) the already-identified EGRET sources (142), suggesting that among the unidentified sources (129) there could still be faint blazars. Due to the presence of a strong non-thermal component inside their jets, blazars are found to display a weaker depression at 4000 Å (K4000<0.4). In this study, we aimed at determining the K4000 break for a selected sample among the potential blazar candidates from unidentified EGRET sources to confirm their blazar nature. We used two blazar candidates, 3EGJ1800-0146 and 3EGJ1709-0817 associated with radio counterparts, J1802-0207 and J1713-0817, respectively. Their optical counterparts were obtained through spectroscopic observations using Robert Stobie spectrograph (RSS) at the Southern African Large Telescope (SALT) in South Africa. The observed Ca II H & K lines depression at 4000 Å in spectra of these sources show a shallow depression, K4000=0.35+-0.02 and 0.24+-0.01, respectively, suggesting that these sources are blazar candidates. Moreover, the redshifts z=0.165 and 0.26 measured in their spectra confirm the extragalactic nature of these sources.

description: We report the results of a survey of OVI 1032 absorption along the lines of sight to 25 white dwarfs in the local interstellar medium (LISM) obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE). We find that interstellar OVI absorption along all sightlines is generally weak, and in a number of cases, completely absent. No OVI absorption was detected with significance greater than 2 sigma for 12 of the 25 stars, where the 1 sigma uncertainty is 4 mA, equivalent to an OVI column density of ~3 x 10^12 cm^-2. Of the remaining stars, most have column densities N(OVI) < 10^13 cm^-2 and no column densities exceed 1.7 x 10^13 cm^-2. For lines of sight to hot (T_eff > 40,000 K) white dwarfs, there is some evidence that the OVI absorption may be at least partially photospheric or circumstellar in origin. We interpret the "patchy" distribution of OVI absorption in terms of a model where OVI is formed in evaporative interfaces between cool clouds and the hot, diffuse gas in the Local Bubble (LB). If the clouds contain tangled or tangential magnetic fields, then thermal conduction will be quenched over most of the cloud surface, and OVI will be formed only in local "patches" where conduction is allowed to operate. We find an average OVI space density in the LISM of 2.4 x 10^-8 cm^-3, which is similar to, or slightly larger than, the value in the Galactic disk over kpc scales. This local density implies an average OVI column density of ~7 x 10^12 cm^-2 over a path length of 100 pc within the LB. The OVI data presented here appears to be inconsistent with the model proposed by Breitschwerdt & Schmutzler (1994), in which highly ionized gas at low kinetic temperature (~50,000 K) permeates the LB. Our survey results are consistent with the supernova-driven cavity picture of Cox & Smith (1974).

Mothers’ experiences of French mothertongue maintenance : towards a critical literacy approach
Creators: name: Iqbal, Isabeau Anisa
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this research was to explore how francophone mothers, having taken on the primary responsibility of teaching French to their young children, experience loss of their mothertongue and describe support and barriers to regaining and maintaining their native language. The principal research questions were: 1) How do francophone mothers residing in Greater Vancouver perceive the experience of maintaining and regaining their mothertongue? 2) How do francophone women living in an English-majority city feel supported or challenged in their decision to speak and improve their French while they take on the primary responsibility for teaching French to their pre-school aged children? 3) How do the women connect their experience of motherhood with their own language maintenance and revival? A literature review indicated three overall notions: 1) In North America, the ideal mother is portrayed as being sacrificial and ultimately responsible for her children's education and well-being, 2) language, identity and community are closely linked concepts, and 3) critical literacy is an educational process that can assist mothers interpret their social present for the purpose of transformation. A review of the literature produced few studies which included francophone mothers' experiences of maintaining their mother tongue while teaching their children French. Participants were eight women who had one or two children, six years or younger, living at home with whom they spoke solely or predominantly in French. Analysis of the interview transcripts revealed several themes. Firstly, although the women experienced language loss in diverse way, all the participants connected their decision to speak French with their children to an attachment with their own personal and cultural sense of identity. Second, participants described that, as compared to before motherhood, they were much more motivated to communicate in French and participate in various francophone activities. Third, women felt that lack of resources in the community, lack of time and having an English speaking partner limited their ability to actively improve their French. Fourth, participants in the study believed that having a greater number of established activities for children and their parents whereby mothers could connect with one another and build friendships would greatly support their desire to improve their fluency in French. The results of this study have implications for the services provided by associations representing francophones in British Columbia, for official language policy in French-minority Canada, for adult educators working with critical literacy and feminist concerns, and for people interested in promoting family health.

description: The Infrared Astronomical Satellite (IRAS) had a tremendous impact on many areas of modern astrophysics. In particular it revealed the ubiquity of infrared cirrus that are a spectacular manifestation of the interstellar medium complexity but also an important foreground for observational cosmology. With the forthcoming Planck satellite there is a need for all-sky complementary data sets with arcminute resolution that can bring informations on specific foreground emissions that contaminate the Cosmic Microwave Background radiation. With its 4 arcmin resolution matching perfectly the high-frequency bands of Planck, IRAS is a natural data set to study the variations of dust properties at all scales. But the latest version of the images delivered by the IRAS team (the ISSA plates) suffer from calibration, zero level and striping problems that can preclude its use, especially at 12 and 25 micron. In this paper we present how we proceeded to solve each of these problems and enhance significantly the general quality of the ISSA plates in the four bands (12, 25, 60 and 100 micron). This new generation of IRAS images, called IRIS, benefits from a better zodiacal light subtraction, from a calibration and zero level compatible with DIRBE, and from a better destriping. At 100 micron the IRIS product is also a significant improvement from the Schlegel et al. (1998) maps. IRIS keeps the full ISSA resolution, it includes well calibrated point sources and the diffuse emission calibration at scales smaller than 1 degree was corrected for the variation of the IRAS detector responsivity with scale and brightness. The uncertainty on the IRIS calibration and zero level are dominated by the uncertainty on the DIRBE calibration and on the accuracy of the zodiacal light model.

description: Gravitational waves may be one of the few direct observables produced by ultralight bosons, conjectured dark matter candidates that could be the key to several problems in particle theory, high-energy physics and cosmology. These axionlike particles could spontaneously form "clouds" around astrophysical black holes, leading to potent emission of continuous gravitational waves that could be detected by instruments on the ground and in space. Although this scenario has been thoroughly studied, it has not been yet appreciated that both types of detector may be used in tandem (a practice known as "multibanding"). In this paper, we show that future gravitational-wave detectors on the ground and in space will be able to work together to detect ultralight bosons with masses $25 \lesssim μ/\left(10^{-15}\, \mathrm{eV}\right)\lesssim 500$. In detecting binary-black-hole inspirals, the LISA space mission will provide crucial information enabling future ground-based detectors, like Cosmic Explorer or Einstein Telescope, to search for signals from boson clouds around the individual black holes in the observed binaries. We lay out the detection strategy and, focusing on scalar bosons, chart the suitable parameter space. We study the impact of ignorance about the system's history, including cloud age and black hole spin. We also consider the tidal resonances that may destroy the boson cloud before its gravitational signal becomes detectable by a ground-based follow-up. Finally, we show how to take all of these factors into account, together with uncertainties in the LISA measurement, to obtain boson mass constraints from the ground-based observation facilitated by LISA.

Debye temperature in LaHx-LaDy superconductors

description: The Debye temperature, T${_θ}$=(h/2$π$)/k${_B}$$ω$$_θ$, where the Debye frequency $ω$$_θ$ is integrated characteristic frequency of full phonon spectrum, $α$$^2$($ω$)F($ω$). In the BCS theory, T${_θ}$ in conjunction with electron-phonon coupling strength parameter, $λ$$_{e-ph}$, determines the superconducting transition temperature, Tc. Despite a fact that more accurate theory of electron-phonon mediated superconductivity requires the knowledge of full phonon spectrum, $α$$^2$($ω$)F($ω$), which can be very accurately computed by first principles calculation technique, there is no experimental technique which can measure $α$$^2$($ω$)F($ω$) in highly-compressed near-room-temperature (NRT) superconductors. Thus, $ω$$_θ$ remains to be the only measurable parameter of full phonon spectrum, $α$$^2$($ω$)F($ω$), which can be deduced by the fit of experimental temperature-dependent resistance data, R(T), to Bloch-Grüneisen equation. Taking in account that within electron-phonon mediated theory of superconductivity two isotopic counterparts (or, in case of NRT superconductors, the same superconducting phase at different pressures), designated by subscripts of 1 and 2, should be obey the relation of T${_θ}_1$/T${_θ}_2$=T${_c}_1$/T${_c}_2$, there is a way to reaffirm/disprove the electron-phonon mechanism of NRT superconductivity. In this paper, we perform the analysis for R3m-phase of H3S at different pressure, as well as for several superconductors in LaHx-LaDy system and show that there is a large disagreement between experimental data and T${_θ}_1$/T${_θ}_2$=T${_c}_1$/T${_c}_2$. Taking in account that similar disagreement has recently reported in H3S-D3S system, it can be concluded that primary origin for NRT superconductivity remains to be discovered.

description: Humans dislike unequal allocations. Although often conflated, such ‘inequality-averse’ preferences are separable into two elements: egalitarian concern about the variance and maximin concern about the poorest (maximizing the minimum). Recent research has shown that the maximin concern operates more robustly in allocation decisions than the egalitarian concern. However, the real-time cognitive dynamics of allocation decisions are still unknown. Here, we examined participants' choice behaviour with high temporal resolution using a mouse-tracking technique. Participants made a series of allocation choices for others between two options: a ‘non-utilitarian option’ with both smaller variance and higher minimum pay-off (but a smaller total) compared with the other ‘Utilitarian option’. Choice data confirmed that participants had strong inequality-averse preferences, and when choosing non-utilitarian allocations, participants' mouse movements prior to choices were more strongly determined by the minimum elements of the non-utilitarian options than the variance elements. Furthermore, a time-series analysis revealed that this dominance emerged at a very early stage of decision making (around 500 ms after the stimulus onset), suggesting that the maximin concern operated as a strong cognitive anchor almost instantaneously. Our results provide the first temporally fine-scale evidence that people weigh the maximin concern over the egalitarian concern in distributive judgements.

description: Recently, the outbreak of Coronavirus Disease 2019 (COVID-19) has spread rapidly across the world. Due to the large number of affected patients and heavy labor for doctors, computer-aided diagnosis with machine learning algorithm is urgently needed, and could largely reduce the efforts of clinicians and accelerate the diagnosis process. Chest computed tomography (CT) has been recognized as an informative tool for diagnosis of the disease. In this study, we propose to conduct the diagnosis of COVID-19 with a series of features extracted from CT images. To fully explore multiple features describing CT images from different views, a unified latent representation is learned which can completely encode information from different aspects of features and is endowed with promising class structure for separability. Specifically, the completeness is guaranteed with a group of backward neural networks (each for one type of features), while by using class labels the representation is enforced to be compact within COVID-19/community-acquired pneumonia (CAP) and also a large margin is guaranteed between different types of pneumonia. In this way, our model can well avoid overfitting compared to the case of directly projecting highdimensional features into classes. Extensive experimental results show that the proposed method outperforms all comparison methods, and rather stable performances are observed when varying the numbers of training data.

description: The specific purpose of this paper is to estimate the extent to which decoupled payments under the Single Payments Scheme (SPS) are being used (either explicitly or implicitly) in England to support the continuation of activities that were previously supported by area and headage payments. In the absence of a farm survey, the methodology consists of using information on farm accounts collected through England’s Farm Business Survey (FBS), to estimate a multi-output cost function differentiated by farm size and farm type. This cost function, calibrated to match regional prices in England, is used to estimate the level of cross-subsidisation in the first full year after implementation of the SPS (2005/06). Results indicate that cross-subsidisation was occurring, which might infer that many farmers across England are coupling their payments. Whilst, these results are for the first year, and in that sense may reflect a transitional situation, they are nevertheless important because they provide empirical evidence to inform the discussion concerning the impact and future development of the SPS.

description: We develop an automated technique to measure quasar redshifts in the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey (SDSS). Our technique is an extension of an earlier Gaussian process method for detecting damped Lyman-alpha absorbers (DLAs) in quasar spectra with known redshifts. We apply this technique to a subsample of SDSS DR12 with BAL quasars removed and redshift larger than 2.15. We show that we are broadly competitive to existing quasar redshift estimators, disagreeing with the PCA redshift by more than 0.5 in only 0.38% of spectra. Our method produces a probabilistic density function for the quasar redshift, allowing quasar redshift uncertainty to be propagated to downstream users. We apply this method to detecting DLAs, accounting in a Bayesian fashion for redshift uncertainty. Compared to our earlier method with a known quasar redshift, we have a moderate decrease in our ability to detect DLAs, predominantly in the noisiest spectra. The area under curve drops from 0.96 to 0.91. Our code is publicly available.

Resummed Kinetic Field Theory: a model of coupled baryonic and dark matter

description: We present a new analytical description of cosmic structure formation in a mixture of dark and baryonic matter, using the framework of Kinetic Field Theory (KFT) -- a statistical field theory for classical particle dynamics. So far, KFT has only been able to describe a single type of particles, sufficient to consider structure growth due to the gravitational interactions between dark matter. However, the influence of baryonic gas dynamics becomes increasingly relevant when describing smaller scales. In this paper, we thus demonstrate how to extend the KFT formalism as well as a previously presented resummation scheme towards describing such mixtures of two particle species. Thereby, the gas dynamics of baryons are accounted for using the recently developed model of Mesoscopic Particle Hydrodynamics. Assuming a flat $Λ$CDM Universe and a simplified model for the thermal gas evolution, we demonstrate the validity of this approach by computing the linear evolution of the individual and total matter power spectra between the epoch of recombination and today. Our results correctly reproduce the expected behaviour, showing a suppression of both baryonic and dark matter structure growth on scales smaller than the baryonic Jeans length, in good agreement with results from the numerical Boltzmann solver CLASS. Nonlinear corrections within this approach will be investigated in upcoming works.

description: We study density profiles in trapped fermionic gases, near Feshbach resonances, at all $T \leq T_c$ and in the near-BEC and unitary regimes. For the latter, we quantify and characterize the generally neglected contribution from noncondensed Cooper pairs. As a consequence of these pairs, our profiles are rather well fit to a Thomas-Fermi (TF) functional form, and equally well fit to experimental data. Our work lends support to the notion that TF fits can be used in an experimental context to obtain information about the temperature.

description: Based on the comprehensive Impact assessment of potential changes to the CAP that accompanied the HC legal proposals tabled by the Commission on 20th May 2008, this paper focuses on the impact analysis of options for adjustment of the Single Payment Scheme. It is put in evidence the distributional implications of the current SPS models as well as the link between the payment distribution with structural variables. Open issues that lead to the need of adjusting the system are also presented. The economic impact of alternative options are analysed based on Eurostat, audit, and microeconomic data. Issues examined include the impact of options on the distribution of payments, on land values, and on farmers income by size and specialisation. Results put in evidence the need to allow MS to consider a targeted adjustment towards a flatter rate for payments, which would address the societal concerns of unequal distribution of payments between farmers.

description: We present waveguides with photonic crystal cores, supporting energy propagation in subwavelength regions with a mode structure similar to that in telecom fibers. We design meta-materials for near-, mid-, and far-IR frequencies, and demonstrate efficient energy transfer to and from regions smaller than 1/25-th of the wavelength. Both positive- and negative-refractive index light transmissions are shown. Our approach, although demonstrated here in circular waveguides for some specific frequencies, is easily scalable from optical to IR to THz frequency ranges, and can be realized in a variety of waveguide geometries. Our design may be used for ultra high-density energy focusing, nm-resolution sensing, near-field microscopy, and high-speed all-optical computing.

HEALTH CHECK AND FARM EFFICIENCY: A COMPARATIVE ASSESSMENT OF FOUR EUROPEAN AGRICULTURAL REGIONS

description: The European Commission has always considered the Common Agricultural Policy (CAP) as a dynamic political tool that aims to link the agricultural sector with the evolving of the economic, financial, social and political dynamics that distinguish the Member States of the European Union. From this standpoint, the Health Check (HC) is much more than a simple assessment of the state of health of European agriculture; it is a drawing up of the “new rules” that are to manage the relations between farms and the market, on which the future efficiency and survival of the said farms and the production sectors that characterise entire European agricultural regions will depend. In this context, the aim of this paper is to present and analyse the "innovations" of the future CAP compared to the current subsidy management system. In particular, the impact of the modifications of the HC – relative to the methods for funding farms due to the transition to the regionalised Single (Farm) Payment Scheme (SPS) and to the new rates of modulation – on the competitiveness of farms specialised in certain production sectors of four European regions will be considered: Emilia- Romagna (IT), Kassel (DE), Anatoliki-Makedonia-Thraki (GR) and Ostra Mallansverige (SE). The assessment of the impact of the HC on the competitiveness of farms is made by taking the technical efficiency index, estimated by a DEA model, as a proxy for the capacity of farms to use factors of production to their best advantage with respect to the farming system adopted and hence to be able to be competitive with other enterprises in the same sector. At the same time, the analysis of the impact of the HC measures is carried out using the “generalised” Positive Mathematical Programming method in order to enable a comparison between European regions. The integration of the two methods applied to the data of the European FADN enables an in-depth assessment of the impacts and a critical evaluation of the goals that the Community reform proposal is expected to attain.

description: We investigate the generation of fractional-period states in continuum periodic systems. As an example, we consider a Bose-Einstein condensate confined in an optical-lattice potential. We show that when the potential is turned on non-adiabatically, the system explores a number of transient states whose periodicity is a fraction of that of the lattice. We illustrate the origin of fractional-period states analytically by treating them as resonant states of a parametrically forced Duffing oscillator and discuss their transient nature and potential observability.
