description: The measurement of farm economic viability has received intermittent academic interest with limited attention given to the conceptual framework surrounding the issue. This paper focuses attention on farm economic viability in Ireland where there are growing concerns about a two-tiered agricultural sector with increasing levels of economic vulnerability. The measurement of farm economic viability is usually based on the headcount ratio, which identifies whether a farm business is viable or non-viable and does not inform about the extent of non-viability. Therefore, it is necessary to develop alternative techniques to provide more clarity on viability levels. This paper draws on concepts from the poverty literature to develop a viability gap measure and a viability severity measure. The trends in farm economic viability are sensitive to the choice of indicator with notable differences between the headcount ratio and the viability gap. The results point to a significant cohort of acutely non-viable cattle and sheep farms. The headcount ratio provides the basis for an incomplete assessment of viability levels and multiple indicators should be considered in monitoring viability levels.

description: We derive type II supergravity solutions corresponding to space-filling regular and fractional Dp branes on (9-p)-dimensional conical transverse spaces. Fractional Dp-branes are wrapped D(p+2)-branes; therefore, our solutions exist only if the base of the cone has a non-vanishing Betti number b_2. We also consider 11-dimensional SUGRA solutions corresponding to regular and fractional M2 branes on 8-dimensional cones whose base has a non-vanishing b_3. (In this case a fractional M2-brane is an M5-brane wrapped over a 3-cycle.) We discuss the gauge theory intepretation of these solutions, as well as of the solutions constructed by Cvetic et al. in hep-th/0011023 and hep-th/0012011.

description: Usability is crucial for the adoption of software development technologies. This is especially true in development stages, where build processes fail, because software is not yet complete or was incompletely modified. We present early work that aims to improve usability of the Combinatory Logic Synthesizer (CL)S framework, especially in these stages. (CL)S is a publicly available type-based development tool for the automatic composition of software components from a user-specified repository. It provides an implementation of a type inhabitation algorithm for Combinatory Logic with intersection types, which is fully integrated into the Scala programming language. Here, we specifically focus on building a web-based IDE to make potentially incomplete or erroneous input specifications for and decisions of the algorithm understandable for non-experts. A main aspect of this is providing graphical representations illustrating the step-wise search process of the algorithm. We also provide a detailed discussion of possible future work to further improve the understandability of these representations.

description: A new Riemann solver is presented for the ideal magnetohydrodynamics (MHD) equations with the so-called Boris correction. The Boris correction is applied to reduce wave speeds, avoiding an extremely small timestep in MHD simulations. The proposed Riemann solver, Boris-HLLD, is based on the HLLD solver. As done by the original HLLD solver, (1) the Boris-HLLD solver has four intermediate states in the Riemann fan when left and right states are given, (2) it resolves the contact discontinuity, Alfvén waves, and fast waves, and (3) it satisfies all the jump conditions across shock waves and discontinuities except for slow shock waves. The results of a shock tube problem indicate that the scheme with the Boris-HLLD solver captures contact discontinuities sharply and it exhibits shock waves without any overshoot when using the minmod limiter. The stability tests show that the scheme is stable when $|u| \lesssim 0.5c$ for a low Alfvén speed ($V_A \lesssim c$), where $u$, $c$, and $V_A$ denote the gas velocity, speed of light, and Alfvén speed, respectively. For a high Alfvén speed ($V_A \gtrsim c$), where the plasma beta is relatively low in many cases, the stable region is large, $|u| \lesssim (0.6-1) c$. We discuss the effect of the Boris correction on physical quantities using several test problems. The Boris-HLLD scheme can be useful for problems with supersonic flows in which regions with a very low plasma beta appear in the computational domain.

description: We consider a simple model of a closed economic system where the total money is conserved and the number of economic agents is fixed. In analogy to statistical systems in equilibrium, money and the average money per economic agent are equivalent to energy and temperature, respectively. We investigate the effect of the saving propensity of the agents on the stationary or equilibrium money distribution.The equilibrium probablity distribution of money becomes the usual Gibb's distribution, characteristic of non-interacting agents, when the agents do not save. However with saving, even for local or individual self-interest, the dynamics become cooperative and the resulting asymmetric Gaussian-like stationary distribution acquires global ordering properties. Intriguing singularities are observed in the stationary money distribution in the market, as function of the ``marginal saving propensity'' of the agents.

description: Following cardiac injury, early immune cell responses are essential
for initiating cardiac remodeling and tissue repair. We previously
demonstrated the importance of β2-adrenergic receptors (β2ARs)
in the regulation of immune cell localization following acute cardiac
injury, with deficient leukocyte infiltration into the damaged
heart. The purpose of this study was to investigate the mechanism
by which immune cell-expressed β2ARs regulate leukocyte recruitment
to the heart following acute cardiac injury. Chemokine receptor
2 (CCR2) expression and responsiveness to C-C motif chemokine
ligand 2 (CCL2)-mediated migration were abolished in β2AR knockout
(KO) bone marrow (BM), both of which were rescued by β2AR
reexpression. Chimeric mice lacking immune cell-specific CCR2 expression,
as well as wild-type mice administered a CCR2 antagonist,
recapitulated the loss of monocyte/macrophage and neutrophil recruitment
to the heart following myocardial infarction (MI) observed
in mice with immune cell-specific β2AR deletion. Converse
to β2AR ablation, β2AR stimulation increased CCR2 expression and
migratory responsiveness to CCL2 in BM. Mechanistically, G proteindependent
β2AR signaling was dispensable for these effects,
whereas β-arrestin2–biased β2AR signaling was required for the
regulation of CCR2 expression. Additionally, activator protein 1
(AP-1) was shown to be essential in mediating CCR2 expression
in response to β2AR stimulation in both murine BM and human
monocytes. Finally, reconstitution of β2ARKO BM with rescued expression
of a β-arrestin–biased β2AR in vivo restored BM CCR2 expression
as well as cardiac leukocyte infiltration following MI. These
results demonstrate the critical role of β-arrestin2/AP-1–dependent
β2AR signaling in the regulation of CCR2 expression and recruitment
of leukocytes to the heart following injury.

description: Abstract State Machines (ASMs) have shown to be a suitable high-level specification method for complex, even industrial, systems; the ASMETA framework, supporting several validation and verification activities on ASM models, is an example of a formal integrated development environment. Although ASMs allow modeling complex systems in a rather concise way -and this is advantageous for specification purposes-, such concise notation is in general a problem for verification activities as model checking and theorem proving that rely on tools accepting simpler notations. In this paper, we propose a flattener tool integrated in the ASMETA framework that transforms a general ASM model in a flattened model constituted only of update, parallel, and conditional rules; such model is easier to map to notations of verification tools. Experiments show the effect of applying the tool to some representative case studies of the ASMETA repository.

description: Since 1990 South-Pembrokeshire has seen rapid changes to its once homogenous landscape dominated by dairy farms. An analysis of this differentiation was made using a system-based French method: an ‘agrarian diagnosis’ in which the current situation is perceived as being the result of both the constraints and qualities of the geographic context in which agriculture is situated, and of a history that has shaped its production methods and social structure. 92 semi-structured farm interviews were carried out in a discrete South Pembrokeshire area, formed of 3 different landscape units with a wide diversity of farm types, and combined with literature, documentary and secondary data analysis. From 1990, the relatively similar dairy farms across Pembrokeshire differentiated under sustained income pressure, linked to an output/input price squeeze and a challenging environment for business expansion. Those farms who stayed in dairying used different strategies to expand, at different times. A ruthless selection process took place, as many farms were pushed out of milk into beef and sheep. This was the first step in a trend towards renting out the land and retiring from farming altogether. The reduced pressure on land use in some farms allowed Potato farming to re-emerge in the landscape, among specialized farms and in just one landscape type. Gradually, a complex, interdependent ecosystem of farms has developed, with businesses exchanging outputs and inputs. The detailed modelling of current farming systems using functional ‘archetypes’, examining economic performance and agricultural income, allows us to understand the economic structure of land use. From this we can forecast a likely second turning point in farm evolution arising from the new support policy and emerging post-Brexit and post-Covid economic environment.

description: Contractors will play a vital role in providing farms access to new precision farming technologies, especially in small scale farming systems. We investigate the role of spatial competition among contractors in the uptake of precision farming, the distribution of farmer surplus, and the realization of policy interventions, accounting for alternative spatial pricing schedules. Conceptual analyses and case study show that a lack of spatial competition among contractors hinders uptake of precision farming technology and farmer surplus. The effectiveness of policy interventions to support precision farming among small farms is also contingent on the market structure and pricing schedules of contractors.
Data managers as storytellers: Possible futures for archaeological data reuse.

description: In this presentation we make the case for reorienting approaches to the archaeological data life cycle, including the roles and responsibilities of data stakeholders (e.g., data creators, curators, depositors, managers, users, etc.), around storytelling. Evidenced through the work of the EU-funded Transforming Data Reuse in Archaeology project (www.tetrarchs. org) and related research, the reuse of archaeological data is highly circumscribed, enabling the circulation of stripped down records which facilitate worrisome, denuded narratives about the past. A more concerted approach to archaeological data management that overtly embraces storytelling at all stages in the data life cycle has the potential to constructively impact not only wider public engagements with the data, but also archaeologists’ own professional interpretations and working experiences.
Human-Wildlife Conflict and Its Amelioration

description: Wild animals can pose direct threats to the safety, livelihoods, and well-being of humans, often leading to retaliatory actions against the species perceived to be responsible, which in turn triggers conflicts among different groups about how to address the situation. While human-wildlife conflict is not a new phenomenon, it has become a growing global concern for both conservation and development interests. These conflicts involve a wide range of terrestrial and aquatic species, from large predators like tigers and bears to smaller animals such as otters and invertebrates. Additionally, human-wildlife conflict negatively impacts communities essential for supporting and benefiting from broader conservation efforts, presenting significant challenges to governments and organizations seeking to balance wildlife conservation with sustainable development. As wildlife populations increase or species recover and expand their ranges, human-wildlife conflicts often intensify. Managing these conflicts is complex and dynamic, with effective methods for mitigating wildlife impacts on people and their livelihoods often proving challenging (Madden, 2008). Furthermore, issues of retaliatory persecution or preventative measures against wildlife are complicated by past experiences, fears, perceptions, and underlying social tensions. Therefore, human-wildlife conflicts extend beyond mere species-human interactions, involving multiple stakeholders within specific environmental, social, and economic contexts.

description: The COVID-19 pandemic is a major international health crisis which has resulted in simultaneous economic, social and food security crises. This study aimed to provide a snapshot of the short-term impact of the COVID-19 pandemic on smallholder rice farmers in Côte d’Ivoire. Using three survey types (village-level, farmer association level, and household level), a total of 585 rice farmers were interviewed nine months after the starting of the pandemic in Cote d’Ivoire. Multivariate probit and Poisson regression models were used to analyze the determinants of the impact of the pandemic on farmers and the intensity of the impact, respectively. Results showed that all rice farmers were aware of coronavirus disease, and television and radio were the main sources of knowledge of the pandemic. After one growing season, the pandemic had negative impact on access to inputs, access to hired labor, yield, income and food security. Around 43% of farmers experienced at least one negative impact of the pandemic. About 30% of farmers perceived that the rice yield and income decreased due to the pandemic. Access to inputs and hired labor became more difficult and expensive for about 28% of farmers. Surprisingly, farmers in more remote villages were also affected by the pandemic as well. The main factors that influenced significantly and positively the intensity of the pandemic impact were the household size, being married, being producer of foundation seed, access to credit in the past, facing drought or flood as constraints. The facilitation of credit access for smallholder farmers could be one strategy to avoid food shortages and deficits among value chain actors.
Lattice $ϕ^4$ theory of finite-size effects above the upper critical dimension

description: We present a perturbative calculation of finite-size effects near $T_c$ of the $ϕ^4$ lattice model in a $d$-dimensional cubic geometry of size $L$ with periodic boundary conditions for $d > 4$. The structural differences between the $ϕ^4$ lattice theory and the $ϕ^4$ field theory found previously in the spherical limit are shown to exist also for a finite number of components of the order parameter. The two-variable finite-size scaling functions of the field theory are nonuniversal whereas those of the lattice theory are independent of the nonuniversal model parameters.One-loop results for finite-size scaling functions are derived. Their structure disagrees with the single-variable scaling form of the lowest-mode approximation for any finite $ξ/L$ where $ξ$ is the bulk correlation length. At $T_c$, the large-$L$ behavior becomes lowest-mode like for the lattice model but not for the field-theoretic model. Characteristic temperatures close to $T_c$ of the lattice model, such as $T_{max}(L)$ of the maximum of the susceptibility $χ$, are found to scale asymptotically as $T_c - T_{max}(L) \sim L^{-d/2}$, in agreement with previous Monte Carlo (MC) data for the five-dimensional Ising model. We also predict $χ_{max} \sim L^{d/2}$ asymptotically. On a quantitative level, the asymptotic amplitudes of this large -$L$ behavior close to $T_c$ have not been observed in previous MC simulations at $d = 5$ because of nonnegligible finite-size terms $\sim L^{(4-d)/2}$ caused by the inhomogeneous modes. These terms identify the possible origin of a significant discrepancy between the lowest-mode approximation and previous MC data. MC data of larger systems would be desirable for testing the magnitude of the $L^{(4-d)/2}$ and $L^{4-d}$ terms predicted by our theory.

description: Early afterdepolarizations (EADs) are pathological voltage oscillations in cardiomyocytes that have been observed in response to a number of pharmacological agents and disease conditions. EADs are small voltage fluctuations that occur during the plateau of an action potential. Although a single-cell behavior, EADs can lead to tissue-level arrhythmias, including ventricular tachycardia. Much is currently known about the biophysical mechanisms (i.e., the roles of ion channels and intracellular calcium stores) for EADs, due partially to the development and analysis of mathematical models. This includes the application of slow/fast analysis, which takes advantage of timescale separation inherent in the system to simplify its analysis. We take this further, using a minimal 3D model to demonstrate that the phase-2 EADs are canards that are formed in the neighborhood of a folded node singularity. This knowledge allows us to determine the number of EADs that can be produced for a given parameter set without performing computer simulations, and provides guidance on parameter changes that can facilitate or inhibit EAD production. With this approach, we demonstrate why periodic stimulation, as would occur in an intact heart, preferentially facilitates EAD production when applied at low frequencies,. We also explain the origin of complex alternan dynamics that can occur with intermediate-frequency stimulation, in which varying numbers of EADs are produced with each stimulation. These revelations fall out naturally from an understanding of folded node singularities, but are hard or impossible to glean from a knowledge of the biophysical mechanism for EADs alone. Therefore, an understanding of the canard mechanism is a useful complement to an understanding of the biophysical mechanism that has been developed over years of experimental and computational investigations.

Accommodating differing ontological commitments by building information systems from scratch.
Creators: name: Lukas, Dominik
Publisher: name: Zenodo
Year: 2024

description: Archaeological Information Systems have to be considered as conceptualized knowledge systems and similarly to ontologies, they need to be understood as reflections or even materializations of epistemic cultures (Knorr-Cetina 1999). Within these cultures researchers interact either in accord with a shared conceptualization or in tension with the constraints of conflicting ideas or the inherent structures of the systems. As researcher's positionalities change over time, their expectations change as well. In consequence conceptions and knowledge systems evolve, continuously prompting modifications that can either be accommodated or need to be relegated in regards to considerations for data consistency and coherence with the already recorded information.  In order to determine which knowledge system is most suitable for a given situation or social context, it is necessary to clarify the decision-making processes for each entity structuring the data. Either a group comes to an informed decision to employ a pre-existing conceptualization (e.g. CIDOC-CRM as reference model), or by establishing their own structure and defining the groups’ ideas of how knowledge should be formed within their domain.

Taking seriously the need for interoperability either at the time of development and usage of a fieldrecording system, or at least at the end of a project and the transfer of data into repositories for longterm preservation, in this paper I will present an approach to repeatedly start the development process from scratch in order to accomodate differing conceptualizations of archaeological knowledge. Making use of a tried and true set of frameworks, programming libraries and tools, it is possible to streamline the development process by retaining the prospect of implementing differing data models. I understand this as a compatible or at least complementary approach to the AIR ecosystem, building data logics at once inspried by the CIDOC-CRM as reference model but still allowing for additional conceptions.

description: Alloy is a lightweight formal specification language, supported by an IDE, which has proven well-suited for reasoning about software design in early development stages. The IDE provides a visualizer that produces graphical representations of analysis results, which is essential for the proper validation of the model. Alloy is a rich language but inherently static, so behavior needs to be explicitly encoded and reasoned about. Even though this is a common scenario, the visualizer presents limitations when dealing with such models. The main contribution of this paper is a principled approach to generate instance visualizations, which improves the current Alloy Visualizer, focusing on the representation of behavior.

In this article, the theory is applied to the case of an isotropic configuration and we present numerical and analytical results for the reversible real-time propagation, as well as irreversible evolution towards equilibrium.

description: We study the dynamics of vortices in strongly disordered $d=2$ Josephson junction arrays and superconducting films driven by a current. We find a dynamic phase transition in vortex flow at a current $I_p>I_c$. Below $I_p$ there is plastic flow characterized by an average-velocity correlation length scale $ξ_v$ in the direction of motion, which diverges when approaching $I_p$. Above $I_p$ we find a moving vortex phase with homogeneous flow and short range smectic order. A finite size analysis shows that this phase becomes asymptotically a liquid for large length scales.

On Fractional Instanton Numbers in Six Dimensional Heterotic E_8 x E_8 Orbifolds

description: We show how the level matching condition in six dimensional, abelian and supersymmetric orbifolds of the E_8 x E_8 heterotic string can be given equivalently in terms of fractional gauge and gravitational instanton numbers. This relation is used to restate the classification of the orbifolds in terms of flat bundles away from the orbifold singularities under the constraint of the level matching condition. In an outlook these results are applied to Kaluza-Klein monopoles of the heterotic string on S^1 in Wilson line backgrounds.

description: We evaluate the volatility spillovers among coffee, ethanol, soybeans, reformulated blendstock for oxygenate blending (RBOB) futures prices, and Brazilian spot prices from 2010 to 2020. Using the Diebold and Yilmaz volatility spillover analytical framework (DY), we estimate the total volatility spillover, the gross and net directional volatility spillover. We also analyze the optimal hedge ratio applying the linear quantile regression (QR) model, comparing the optimal hedge ratios with the minimum variance (MV) and error correction model (ECM). Results show an increasing trend in the total volatility spillover index, suggesting an increase in the Brazilian market's connectedness. In addition, we identify quantile ranges where the QR hedge is economical and statistically significant, particularly for extreme spot prices, lower-and-upper quantiles. The knowledge of the volatility spillover effect in agricultural commodity markets may provide additional information for efficient resource allocation decisions about harvesting, output, storage, commercialization, and hedging.

description: We present a new integrable model for correlated electrons which is based on a $so(5)$ symmetry. By using an $η$-pairing realization we construct eigenstates of the Hamiltonian with off-diagonal long-range order. It is also shown that these states lie in the ground state sector. We exactly solve the model on a one-dimensional lattice by the Bethe ansatz.

description: Thermal two-loop QCD corrections associated with light stops have a dramatic effect on the strength of the MSSM electroweak phase transition, making it more strongly first order as required for the viability of electroweak baryogenesis. We perform a perturbative analysis of the transition strength in this model, including these important contributions, extending previous work to arbitrary values of the pseudoscalar Higgs boson mass, m_A. We find a strong enough transition in a region with 2< tan beta < 4 and m_A > 120 GeV, a light Higgs boson with nearly standard couplings, and mass below 85 GeV within the reach of LEP II, and one stop not much heavier than the top quark. In addition, we give a qualitative discussion of the parameter space dependence of the transition strength and comment on the possibility that the transition turns to a crossover for sufficiently large Higgs masses.

Self-adjointness of the two-dimensional massless Dirac Hamiltonian and vacuum polarization effects in the background of a singular magnetic vortex

description: A massless spinor field is quantized in the background of a singular static magnetic vortex in 2+1-dimensional space-time. The method of self-adjoint extensions is employed to define the most general set of physically acceptable boundary conditions at the location of the vortex. Under these conditions, all effects of polarization of the massless fermionic vacuum in the vortex background are determined. Absence of anomaly is demonstrated, and patterns of both parity and chiral symmetry breaking are discussed.

description: New tunneling data are reported in underdoped Bi2Sr2CaCu2O8-d using superconductor-insulator-superconductor break junctions. Energy gaps, Delta, of 51+2, 54+2 and 57+3 meV are observed for three crystals with Tc=77, 74, and 70 K respectively. These energy gaps are nearly three times larger than for overdoped crystals with similar Tc. Detailed examination of tunneling spectra over a wide doping range from underdoped to overdoped, including the Josephson IcRn product, indicate that these energy gaps are predominantly of superconducting origin.

description: We have studied phonon and thermodynamic properties of a body-centered cubic (bcc) Coulomb crystal of ions with weakly polarized electron background in a uniform magnetic field ${\bf B}$. At $B=0$ the difference between phonon moments calculated using the Thomas-Fermi (TF) and random phase (RPA) approximations is always less than one percent and for description of phonon properties of a crystal TF formalism was used. This formalism was successfully applied to investigate thermodynamic properties of magnetized Coulomb crystals. It was shown that the influence of the polarization of the electron background is significant only at $κ_{\rm TF}a > 0.1$ and $T \ll T_{\rm p}(1+h^2)^{-1/2}$, where $κ_{\rm TF}$ is the Thomas-Fermi wavenumber, $a$ is the ion sphere radius, $T_{\rm p}\equiv\hbar ω_{\rm p}$ is the ion plasma temperature, $h\equiv ω_B/ω_{\rm p}$, $ω_B$ is the ion cyclotron frequency and $ω_{\rm p}$ is the ion plasma frequency.

description: By tilting the samples in the magnetic field, we measured and compared the Skyrmion excitations in the bilayer quantum Hall (QH) state at the Landau-level filling factor $ν=2$ and in the monolayer QH state at $ν=1$. The observed number of flipped spins is $N_s=14$ in the bilayer system with a large tunneling gap, and $N_s=7$ in the bilayer system with a small tunneling gap, while it is $N_s=7$ in the monolayer system. The difference is interpreted due to the interlayer exchange interaction. Moreover, we have observed seemingly preferred numbers $N_s=14,7,1$ for the flipped spins by tilting bilayer samples.

Food Security and Poverty

description: This research aims at investigating the impact of food assistance programmes on the resilience to food insecurity levels of rural agricultural households headed by females that are beneficiaries of the project “The R4 Rural Resilience Initiative” of the World Food Programme and Oxfam America’s, implemented during the period 2015-2016. During the empirical analysis, first, resilience and food security levels are estimated using the Resilience Index Measurement and Analysis II methodology of the Food and Agriculture Organization. Second, a reflective and reflexive method are used for a descriptive performance assessment of female vs male-headed households, before and after the project implementation. Finally, matching and difference-in-difference techniques, with an emphasis on gender, are used for impact evaluation. The performance analysis shows positive and significant effects of the project participation on male and female-headed households, being these effects on male-headed larger than in their counterparts. The impact evaluation shows a negative and significant relationship between female headed households’ programme participation and the variation of the outcome variables, but a positive and significant relationship between program participation and the levels of resilience and food security of female-headed households.
