description: In this paper we introduce a Cayley-type graph for group-subgroup pairs and present some elementary properties of such graphs, including connectedness, their degree and partition structure, and vertex-transitivity. We relate these properties to those of the underlying group-subgroup pair. From the properties of the group, subgroup and generating set some of the eigenvalues can be determined, including the largest eigenvalue of the graph. In particular, when this construction results in a bipartite regular graph we show a sufficient condition on the size of the generating sets that results on Ramanujan graphs for a fixed group-subgroup pair. Examples of Ramanujan pair-graphs that do not satisfy this condition are also provided, to show that the condition is not necessary.

description: The Burton-Cabrera-Frank (BCF) model for the flow of line defects (steps) on crystal surfaces has offered useful insights into nanostructure evolution. This model has rested on phenomenological grounds. Our goal is to show via scaling arguments the emergence of the BCF theory for non-interacting steps from a stochastic atomistic scheme of a simplified kinetic solid-on-solid model in one spatial dimension. Our main assumptions are: adsorbed atoms (adatoms) form a dilute system, and elastic effects of the crystal lattice are absent. The step edge is treated as a front that propagates via probabilistic rules for atom attachment and detachment at the step. We formally derive a quasistatic step flow description by averaging out the stochastic scheme when terrace diffusion, adatom desorption and deposition from above are present.

title: "13 reasons why" - warum Medien eine wichtige Rolle hinsichtlich Suizidprävention spielen
Creators: name: Heilig, Fiona
Year: 2021

description: Im Zuge dieser Forschungsarbeit wurde die potenzielle Auswirkung der Netflix-Serie „Tote Mädchen lügen nicht“ auf die österreichische Suizidrate erforscht. Als theoretische Grundlage dienten jene Forschungsarbeiten, welche im Themenbereich „Suizid und Medien“ verortet sind. Der Fokus lag hierbei insbesondere auf Untersuchungen zu fiktionalen Medien. Weiters spielten auch Medienempfehlungen zum Thema Suizid, das Stress-Vulnerabilitäts-Modell nach Wasserman, die theoretischen Überlegungen zu Identifikations- und sozialen Vergleichsprozessen sowie einige weitere Arbeiten, eine essentielle Rolle. Zur Prüfung der Hypothesen wurde ein Methodenmix angewandt. Die von der Statistik Austria zur Verfügung gestellten Suiziddaten, aus den Jahren 2010-2019, wurden mithilfe des zeitreihen-analytischen Verfahrens im Statistikprogramm SPSS ausgewertet. Weiters wurden 26 Instagram-Beiträge der deutschsprachigen Netflix-Seite, mit insgesamt 6.871 Kommentaren, zur ersten sowie zweiten Staffel der Serie mittels einer Inhaltsanalyse erforscht. Die Auswertungen zeigten, dass in den Monaten nach Release der ersten Staffel, sowohl bei den Jugendlichen als auch jungen Erwachsenen ein Anstieg in der Rate entdeckt werden konnte. Überraschenderweise zeigte sich, entgegen der zuvor aufgestellten Hypothese, dass auch nach Release der zweiten Staffel ein Peak in der Gruppe der jungen Erwachsenen zu sehen war. Zudem stellte sich heraus, dass in den Kommentaren eher von negativen Auswirkungen der Serie auf die eigene Person berichtet wurde als positive. Die vorliegende Forschungsarbeit unterstreicht die Wichtigkeit der Kombination von quantitativen und qualitativen Daten, um komplexe Phänomene wie das Thema Suizid, besser verstehen zu können.

description: We develop a new off-shell formulation for five-dimensional (5D) conformal supergravity obtained by gauging the 5D superconformal algebra in superspace. An important property of the conformal superspace introduced is that it reduces to the superconformal tensor calculus (formulated in the early 2000's) upon gauging away a number of superfluous fields. On the other hand, a different gauge fixing reduces our formulation to the SU(2) superspace of arXiv:0802.3953, which is suitable to describe the most general off-shell supergravity-matter couplings. Using the conformal superspace approach, we show how to reproduce practically all off-shell constructions derived so far, including the supersymmetric extensions of $R^2$ terms, thus demonstrating the power of our formulation. Furthermore, we construct for the first time a supersymmetric completion of the Ricci tensor squared term using the standard Weyl multiplet coupled to an off-shell vector multiplet. In addition, we present several procedures to generate higher-order off-shell invariants in supergravity, including higher-derivative ones. The covariant projective multiplets proposed in arXiv:0802.3953 are lifted to conformal superspace, and a manifestly superconformal action principle is given. We also introduce unconstrained prepotentials for the vector multiplet, the ${\cal{O}}(2)$ multiplet (i.e., the linear multiplet without central charge) and ${\cal{O}}(4+n)$ multiplets, with $n=0,1,\dots$ Superform formulations are given for the BF action and the non-abelian Chern-Simons action. Finally, we describe locally supersymmetric theories with gauged central charge in conformal superspace.

description: We study consequences of long-range elasticity in thermally assisted dynamics of yield stress materials. Within a two-dimensinal mesoscopic model we calculate the mean-square displacement and the dynamical structure factor for tracer particle trajectories. The ballistic regime at short time scales is associated with a compressed exponential decay in the dynamical structure factor, followed by a subdiffusive crossover prior to the onset of diffusion. We relate this crossover to spatiotemporal correlations and thus go beyond established mean field predictions.

description: In this work, we use the Born-Oppenheimer approximation where the potential between atoms can be approximated as a function of distance between the two nuclei to study the four-quark bound states. By the approximation, Heitler and London calculated the spectrum of hydrogen molecule which includes two protons (heavy) and two electrons (light). Generally, the observed exotic mesons $Z_b(10610)$, $Z_b(10650)$, $Z_c(3900)$ and $Z_c(4020)$($Z_c(4025)$) may be molecular states made of two physical mesons and/or in diquark-anti-diquark structures. In analog to the Heitler-London method for calculating the mass of hydrogen molecule, we investigate whether there exist energy minima for these two structures. By contrary to the hydrogen molecule case where only the spin-triplet possesses an energy minimum, there exist minima for both of them. It implies that both molecule and tetraquark states can be stable objects. But since they have the same quantum numbers, the two states may mix to result in the physical states. A consequence would be that partner exotic states co-existing with $Z_b(10610)$, $Z_b(10650)$, $Z_c(3900)$ and $Z_c(4020)$($Z_c(4025)$) are predicted and should be experimentally observed.

description: Abstract
In this research work, we used machine learning techniques to predict the creditworthiness of smartphone users in Indonesia after the COVID-19 pandemic. Principal Component Analysis (PCA) and K-means algorithms were used for dimensional reduction and clustering using a dataset of 803 respondents consisting of twelve questions to smartphone users in Indonesia after the COVID-19 pandemic. To classify the creditworthiness of smartphone users in Indonesia, the four different classification algorithms (Logistic Regression, Support Vector Machine, Decision Tree, and Naïve Bayes) were tested. The tests carried out included testing for accuracy, precision, recall, F1-score, and Area Under Curve Receiver Operating Characteristics (AUCROC) assessment.  When compared to other models, the Logistic Regression algorithm outperforms them. The findings of this study also provide new information about the most influential and non-influential variables based on the twelve questions posed to smartphone users in Indonesia, which can assist financial institutions, particularly banks, in assessing the creditworthiness of prospective customers after COVID-19 pandemic.

description: We revisit constraints on the (pseudo)conformal Universe from the non-observation of statistical anisotropy in the Planck data. The quadratic maximal likelihood estimator is applied to the Planck temperature maps at frequencies 143 GHz and 217 GHz as well as their cross-correlation. The strongest constraint is obtained in the scenario of the (pseudo)conformal Universe with a long intermediate evolution after conformal symmetry breaking. In terms of the relevant parameter (coupling constant), the limit is h^2 <0.0013 at 95% C.L. (using the cross-estimator). The analogous limit is much weaker in the scenario without the intermediate stage (h^2 \ln \frac{H_0}Λ<0.52) allowing the coupling constant to be of order one. In the latter case, the non-Gaussianity in the 4-point function appears to be a more promising signature.

Year: 2023
Subjects: Digital Health, Digital Entrepreneurship, Business Model, Value Proposition Model.

description: Abstract
Aims: Digital health is the use of digital technologies in health and healthcare systems to improve the performance of healthcare delivery by providing more customized and impeccable treatments. Thus, digital health entrepreneurs want to exploit information and communication technology to help solving health problems and challenges to ensure well-being among people in treatment. They contribute to create innovative digital health products or solutions and are promptly transforming the medical practices by shaping the relationship between health professionals and patients. This paper aims to outline the literature review regarding digital health entrepreneurship and to scrutinize different features of Digital Health Business Model. Digital health entrepreneurs conceive strong business models to exploit several ignored market opportunities. To be effective, the Digital Health Entrepreneur should deeply understand patients' needs and wants for the potential expected value that he could create develop and control. The value proposition have to be attractive enough for each customer segment in the healthcare system in order to sustain the digital health business. Thus, to create a strong value proposition, the digital health entrepreneurs have to recognize their targeted customers' traits, needs, expectations and wants. Therefore, patients have to be their own-doctor by being experts on their own health and they should find digital channels to be up to date. By being up-to-date on the appropriate use of technology as patients do, digital health entrepreneurs contribute in the establishment of a participatory medicine based on patient centric strategies to make life patients more easily and comfortable.

description: Inspired by the new soft theorem in gravity by Cachazo and Strominger, the soft theorem for color-ordered Yang-Mills amplitudes has also been identified by Casali. In this note, the same content of N=4 SYM using the Grassmannian formulation is studied. Explicitly, in the holomorphic soft limit, we reduce the n-particle amplitude in terms of Grassmannian contour integrations into the deformed (n-1)-particle amplitude by localizing k variables relevant to the n-th particle. Afterwards, the leading soft factor and sub-leading soft operator naturally emerge.

description: Open Science is gaining more and more ground among academics. This has consequences for research libraries and their staff tasked with services supporting the entire research life cycle, from providing access to relevant databases, to research data management, to scholarly publishing. To stay relevant, research library services have to be developed and adapted to support Open Science research activities. Therefore, it is important to investigate what competencies and skills are needed to provide a given library service, both in terms of continuing education and training of existing library staff and of curriculum development in library and information science education. There are several international initiatives that either facilitate the upskilling of researchers and research staff within Open Science (e.g. the EC’s “Open Science Skills Working Group report” [1] and FOSTER’s materials and online courses [2]) or provide a framework for research libraries of how to engage in Open Science support (e.g. LIBER’s “Open Science Roadmap” [3]). These initiatives lay out general lines of action that can serve as starting points for more locally focused activities. Furthermore, the EDISON project has provided competency profiles for data professionals that can be used for curriculum design within higher and continuing education [4]. In our poster, we present a project, currently funded by Denmark’s Electronic Research Library (DEFF), that investigates, models, and deploys Open Science skills for Danish research librarians. The project comprises three subprojects that focus on 1) a general model of Open Science competencies and skills for research librarians, 2) an overview of Danish digital collections, with a focus on openness and applicability, 3) the identification of current and future RDM services and tools at Danish research libraries and a model of RDM competencies and skills for research librarians. The project started in March 2018 and will run until March 2020. We present initial considerations and the research design of the subprojects 1) and 3). We provide insights into the challenges encountered when introducing general international frameworks into a national context.

The results are based on calculations which include the resummation of soft-gluon emission at next-to-leading logarithmic accuracy, matched to next-to-leading order supersymmetric QCD corrections. Furthermore, we provide an estimate of the theoretical uncertainty due to the variation of the renormalisation and factorisation scales and the parton distribution functions.

Asymmetric price transmission in the brazilian refined sugar market

Publisher: name: Italian Review of Agricultural Economics
Year: 2018

description: This work evaluates the price relations and transmission patterns between producers and retail in the market for refined sugar in Sao Paulo, Brazil, its direction and magnitude. The results suggest that the transmission of shocks is bidirectional. Formal tests suggest that the symmetry in price transmission from retail to producer cannot be rejected in short and long-run. Therefore, positive and negative exogenous shocks of refined sugar at the retail impact producer’s prices in the same magnitude. From producer to retail prices, the tests confirmed a negative asymmetry in price transmission. It means that a reduction in producer prices has a stronger impact in reducing retail prices than when a positive shock on producer prices is transmitted to increase retail prices.

Three-Dimensional Simulations of Core-Collapse Supernovae: From Shock Revival to Shock Breakout

description: We present 3D simulations of core-collapse supernovae from blast-wave initiation by the neutrino-driven mechanism to shock breakout from the stellar surface, considering two 15 Msun red supergiants (RSG) and two blue supergiants (BSG) of 15 Msun and 20 Msun. We demonstrate that the metal-rich ejecta in homologous expansion still carry fingerprints of asymmetries at the beginning of the explosion, but the final metal distribution is massively affected by the detailed progenitor structure. The most extended and fastest metal fingers and clumps are correlated with the biggest and fastest-rising plumes of neutrino-heated matter, because these plumes most effectively seed the growth of Rayleigh-Taylor (RT) instabilities at the C+O/He and He/H composition-shell interfaces after the passage of the SN shock. The extent of radial mixing, global asymmetry of the metal-rich ejecta, RT-induced fragmentation of initial plumes to smaller-scale fingers, and maximal Ni and minimal H velocities do not only depend on the initial asphericity and explosion energy (which determine the shock and initial Ni velocities) but also on the density profiles and widths of C+O core and He shell and on the density gradient at the He/H transition, which lead to unsteady shock propagation and the formation of reverse shocks. Both RSG explosions retain a great global metal asymmetry with pronounced clumpiness and substructure, deep penetration of Ni fingers into the H-envelope (with maximum velocities of 4000-5000 km/s for an explosion energy around 1.5 bethe) and efficient inward H-mixing. While the 15 Msun BSG shares these properties (maximum Ni speeds up to ~3500 km/s), the 20 Msun BSG develops a much more roundish geometry without pronounced metal fingers (maximum Ni velocities only ~2200 km/s) because of reverse-shock deceleration and insufficient time for strong RT growth and fragmentation at the He/H interface.

description: Precision agriculture (PA) has not yet spread in Brazil, despite the benefits stressed in literature. Considering the uncertainty related to PA’s results, this study evaluated the tradeoff between risks and returns for precision production of soybeans in Mato Grosso do Sul state, Brazil. A representative farm using PA was compared to a conventional production system through the Earnings-at-Risk metric and a Modified Sharpe Index. PA presented higher expected earnings per hectare while conventional production proved to have a lower risk exposure. The positive difference in expected earnings between precision and conventional systems was insufficient to cover PA’s risk exposure, leading to the conclusion that less risk-averse farmers could assume higher risks and prefer precision system.

description: The quantum navigation problem of finding the time-optimal control Hamiltonian that transports a given initial state to a target state through quantum wind, that is, under the influence of external fields or potentials, is analysed. By lifting the problem from the state space to the space of unitary gates realising the required task, we are able to deduce the form of the solution to the problem by deriving a universal quantum speed limit. The expression thus obtained indicates that further simplifications of this apparently difficult problem are possible if we switch to the interaction picture of quantum mechanics. A complete solution to the navigation problem for an arbitrary quantum system is then obtained, and the behaviour of the solution is illustrated in the case of a two-level system.

In the first paper of the series, we gave a decomposition of the graph $G$ into several parts of different characteristics; this decomposition might be viewed as an analogue of a regular partition for sparse graphs. In the present paper, we find a combinatorial structure inside this decomposition. In the last two papers, we refine the structure and use it for embedding the tree $T$.

description: Multifarious sources of selection shape visual signals and can produce phenotypic divergence. Theory predicts that variance in warning signals should be minimal due to purifying selection, yet polymorphism is abundant. While in some instances divergent signals can evolve into discrete morphs, continuously variable phenotypes are also encountered in natural populations. Notwithstanding, we currently have an incomplete understanding of how combinations of selection shape fitness landscapes, particularly those which produce polymorphism. We modelled how combinations of natural and sexual selection act on aposematic traits within a single population to gain insights into what combinations of selection favours the evolution and maintenance of phenotypic variation. With a rich foundation of studies on selection and phenotypic divergence, we reference the poison frog genus Oophaga to model signal evolution. Multifarious selection on aposematic traits created the topology of our model's fitness landscape by approximating different scenarios found in natural populations. Combined, the model produced all types of phenotypic variation found in frog populations, namely monomorphism, continuous variation and discrete polymorphism. Our results afford advances into how multifarious selection shapes phenotypic divergence, which, along with additional modelling enhancements, will allow us to further our understanding of visual signal evolution.
La gestione del rischio nella zona DOCG Conegliano-Valdobbiadene, valutazioni economiche

description: The risk management policy in agriculture has become particularly prominent, considering the evolution of the CAP and the dreaded climate change. The aim is the evaluation of economic convenience to join to risk management tools provided to winegrowers in the DOCG area of Conegliano-Valdobbiadene. The study makes use of specific information gathered by Condifesa and proposes an original efficiency indicator of the subsidies. The analysis shows that the subsidized insurance alone is no longer the most adequate. Only the drafting of a supplementary coverage can minimize the loss function. The prediction of more severe weather events suggests that maybe only a higher risk perception can be an enticing premise for the development of a solid insurance market.

description: This collaborative autoethnography (Bochner and Ellis, 2016) has created a space for three women academics from working-class heritage, navigating the liminal and temporal space of the COVID-19 pandemic within a post-1992 Higher Education Institution, to explore the social relations of one Higher Education Institution and confront their lived experiences. The stories shared in this paper are analysed through a ‘care-less’ (Rogers, 2017) lens, which asks the academy to recognise and confront the duplicity and self-glorification of policy and practice, that might be viewed as acts of normalising and supporting care-less cultures and behaviours. The paper raises questions about social justice, diversity and inclusion, the intersectionality of class and gender, and the inequity of the lived experiences from those who sit on the margins. The paper is the first collaborative writing project from a newly formed staff network of academics who come from working-class backgrounds, and we are intentional in our commitment to support each other as new researchers, giving agency in support of the other to find their voice.

description: Empirical data on contacts between individuals in social contexts play an important role in providing information for models describing human behavior and how epidemics spread in populations. Here, we analyze data on face-to-face contacts collected in an office building. The statistical properties of contacts are similar to other social situations, but important differences are observed in the contact network structure. In particular, the contact network is strongly shaped by the organization of the offices in departments, which has consequences in the design of accurate agent-based models of epidemic spread. We consider the contact network as a potential substrate for infectious disease spread and show that its sparsity tends to prevent outbreaks of rapidly spreading epidemics. Moreover, we define three typical behaviors according to the fraction $f$ of links each individual shares outside its own department: residents, wanderers and linkers. Linkers ($f\sim 50\%$) act as bridges in the network and have large betweenness centralities. Thus, a vaccination strategy targeting linkers efficiently prevents large outbreaks. As such a behavior may be spotted a priori in the offices' organization or from surveys, without the full knowledge of the time-resolved contact network, this result may help the design of efficient, low-cost vaccination or social-distancing strategies.

description: The Italian Budget Law for 2018 has postponed the increase of the ordinary and reduced VAT rates announced from 2018 to 2019, 2020 and 2021. On the basis of this law, by 1st January 2021, the 22% ordinary VAT rate will reach 25% and the reduced 10% VAT rate will increase to 13%. This paper examines the effects of the increase of VAT rates on food products by identifying the agricultural sectors more at risk of economic crisis as a consequence of the possible reduction of the food and agricultural demand. The novelty of this research consists on the method based on the construction of a composite indicator and its application to tax return data. Results show that the wine sector and other sectors more linked with the meat supply chain are those more exposed to the increase of VAT rates.

description: Abstract
Students at primary stage usually face difficulty in understanding scientific subjects, especially abstract sciences. Therefore, relying on traditional learning methods only will lead to a lack creative thinking in the learning process and a weak readiness to continue in the study, this scenario requires alternative learning methods such as visual effects based on digital content. The aim of this study is to examine the interrelationships between visual effects in digital content, creative thinking, learning readiness, student performance. This study applied quantitative methods to analyze the relationships between visual effects in digital content, creative thinking, learning readiness, and student performance. The population is the teaching staff in primary schools of UAE. Data instrument is self-administrated questionnaire. The data collection has been conducted on a sample of 700 teachers in 248 schools in Abu Dhabi. Simple random sampling technique has been applied in the survey procedure. SPSS software is deployed to conduct data analysis. Regression analysis and SEM have been deployed to conduct data analysis and test the hypothesis of this study. The result revealed that visual effects in digital content has a significant effect on creative thinking, learning readiness, and student performance, as well as creative thinking and learning readiness have significant effects on student performance. To that end, incorporating visual effects into digital textbooks is a promising approach to improving the educational experience of students in the UAE. Therefore, this study recommend inclusion of visual effects in education curriculum is necessary, whereas more studies on this field should help the policymakers in the ministry of education to regulate alternative learning methods and set new guidelines for this goal.

description: Italian university farms provide a crucial support for teaching, research and innovation transfer in the agro-food, forestry, environmental and even social sectors. In order to point out their current values and weaknesses, and to start reflecting on possible development strategies, a survey was realised. A questionnaire was sent to the 25 Italian universities providing courses in the agro-food and forestry sectors. The main weaknesses emerged concern the availability of the required data, in particular economic data, and the economic sustainability of these farms, especially with regard to staff costs. Moreover, the survey made it possible to outline for the first time a cognitive framework of the Italian university farms, thus creating a useful database for future updates and insights.

QUANTUM PROBING AND CHARACTERIZATION TECHNIQUES FOR SYSTEMS OF INTEREST IN QUANTUM INFORMATION PROCESSING.

description: The thread of this thesis is an attempt to clarify some assumptions that sound reasonable but whose correctness has never been proved or demonstrated formally. The first question I consider is: Do two quantum states near in the Hilbert space have the same, or almost the same, physical properties? First of all we have to clarify with which kind of measure we would like to measure the distance between two states. I do consider a measure, called Fidelity, that acts from the Hilbert space of a bipartite system to [0; 1]. Fidelity is null when the two states are orthogonal while if it is 1 the two states coincides. I show that high fidelities may be achieved by pairs of states with considerably different physical properties, including separable and entangled states or classical and nonclassical ones. Therefore, fidelity alone cannot be used to asses the very quantum properties of two states,but a tomographic reconstruction of the state is required. Secondly I question: Does a good quantum thermometer could be build with a system showing phase transition? I employ a critical magnetic system, known as Lipkin-Meshkov-Glick model, I study it in contact with a reservoir with it has thermalized but whose temperature is an unknown temperature to be estimated. I show that the best precision for temperature estimation it is not at critical point as someone could suspect but nevertheless criticality is an unmatchable resource even in the quantum realm. Last question is: when two different probes spatially separated interact with a common or a separate bath? It is quite a common opinion that systems, two objects located far away one from each others, feel the effect of different environments. Dissipation and decoherence are the two main processes which a quantum system undergo when it is not isolated, but when it interacts with another system much bigger. I explore how two different systems put in contact with a common bath show decoherence with typical quantum interference leading to a non obvious definition of separate environments.
Link between R&D intensity and market concentration: analysis of Brazilian corn and soybean seed markets

description: Innovation in the Brazilian seed markets is one of the main driver of the Brazilian agricultural expansion during the last decades. However, these markets also experienced a market reconsolidation in the form of a market concentration. In this paper, we test the hypothesis that there is an inverse relationship between innovations and market structure at the seed market. We use a Generalized Method of Moments model applied to a theoretical framework that allowed us to determine the direction of this relationship. Our results suggested that this link depends on market characteristics, such as the introduction of genetically modified organisms (GMO). For corn (soybean), we find a positive (negative) relationship between these factors that has become negative (positive) in the period post-GMO introduction.

Log-Gamma directed polymer with fixed endpoints via the replica Bethe Ansatz

description: We study the model of a discrete directed polymer (DP) on the square lattice with homogeneous inverse gamma distribution of site random Boltzmann weights, introduced by Seppalainen. The integer moments of the partition sum, $\overline{Z^n}$, are studied using a transfer matrix formulation, which appears as a generalization of the Lieb-Liniger quantum mechanics of bosons to discrete time and space. In the present case of the inverse gamma distribution the model is integrable in terms of a coordinate Bethe Ansatz, as discovered by Brunet. Using the Brunet-Bethe eigenstates we obtain an exact expression for the integer moments of $\overline{Z^n}$ for polymers of arbitrary lengths and fixed endpoint positions. Although these moments do not exist for all integer n, we are nevertheless able to construct a generating function which reproduces all existing integer moments, and which takes the form of a Fredholm determinant (FD). This suggests an analytic continuation via a Mellin-Barnes transform and we thereby propose a FD ansatz representation for the probability distribution function (PDF) of $Z$ and its Laplace transform. In the limit of very long DP, this ansatz yields that the distribution of the free energy converges to the GUE Tracy-Widom distribution up to a non-trivial average and variance that we calculate. Our asymptotic predictions coincide with a result by Borodin et al. based on a formula obtained by Seppalainen using the gRSK correspondence. In addition we obtain the dependence on the endpoint position and the exact elastic coefficient at large time. We argue the equivalence between our formula and the one of Borodin et al. As we discuss, this open the way to explore the connections between quantum integrability and tropical geometry.

description: This paper examines Brazilian rural establishments which carry out both agricultural and non-agricultural activities. The combination of these activities, in the same agricultural unit, characterizes and defines pluriactivity. The research aims to analyze the effect of pluriactivity on the technical efficiency of rural establishments. To do so, Propensity Score Matching (PSM), a Probit Model and the Stochastic Production Frontier were used. The data used refer to a special tabulation, based on the micro-data of the 2006 Agricultural Census. The results found that establishments which carry out exclusively agricultural activities make better use of available resources than those involved in pluriactivity, as they are technically more efficient.

description: The debate over the Common Agricultural Policy (CAP) after 2020 is mainly focused on making more effective the public expenditure on agriculture. Specific attention is given to the Basic Payment Scheme (BPS) of Pillar I, which is criticized for being unequally distributed and scarcely targeted towards specific and measurable goals. The present paper is aimed to evaluate whether and how the choice of land as a criterion for redistributing and receiving aids affects the ability of the BPS to enhance farm incomes. To this end, the Italian version of the Farm Accountancy Data Network is used. Findings reveal that other parameters, such as work and value added, should be also taken into account in order to improve the effectiveness of BPS in increasing incomes of Italian farms.
