description: We study the problem of instanton generated superpotentials in Calabi-Yau orientifold compactifications directly in type IIB string theory. To this end, we derive the Dirac equation on a Euclidean D3 brane in the presence of background fluxes. We propose an index which governs whether the generation of a superpotential in the effective 4d theory by D3 brane instantons is possible. Applying the formalism to various classes of examples, including the K3 x T^2/Z_2 orientifold, in the absence and presence of fluxes, we show that our results are consistent with conclusions attainable via duality from an M-theory analysis.

description: We study codimension-even conical defects that contain a deficit solid angle around each point along the defect. We show that they lead to a delta function contribution to the Lovelock scalar and we compute the contribution by two methods. We then show that these codimension-even defects appear as Euclidean brane solutions in higher dimensional topological AdS gravity which is Lovelock-Chern-Simons gravity without torsion. The theory possesses a holographic Weyl anomaly that is purely of type-A and proportional to the Lovelock scalar. Using the formula for the defect contribution, we prove a holographic duality between codimension-even defect partition functions and codimension-even brane on-shell actions in Euclidean signature. More specifically, we find that the logarithmic divergences match, because the Lovelock-Chern-Simons action localizes on the brane exactly. We demonstrate the duality explicitly for a spherical defect on the boundary which extends as a codimension-even hyperbolic brane into the bulk. For vanishing brane tension, the geometry is a foliation of Euclidean AdS space that provides a one-parameter generalization of AdS-Rindler space.

description: We give a rigorous proof that the (codimension one) Connes-Moscovici Hopf algebra H_CM is isomorphic to a bicrossproduct Hopf algebra linked to a group factorisation of the group of positively-oriented diffeomorphisms of the real line. We construct a second bicrossproduct U_CM equipped with a nondegenerate dual pairing with H_CM. We give a natural quotient Hopf algebra of H_CM and Hopf subalgebra of U_CM which again are in duality. All these Hopf algebras arise as deformations of commutative or cocommutative Hopf algebras that we describe in each case. Finally we develop the noncommutative differential geometry of the quotient of H_CM by studying covariant first order differential calculi of small dimension over this algebra.

description: Tropical America is currently experiencing the establishment of a new apex insect predator, the Paleotropical dragonfly Hemianax ephippiger (Odonata: Aeshnidae). H. ephippiger is migratory and is suggested to have colonised the eastern Neotropics by chance Trans-Atlantic displacement. We report the discovery of H. ephippiger at three new locations in the Caribbean, the islands of Bonaire, Isla de Coche (Venezuela), and Martinique, and we review its reported distribution across the Neotropics. We discuss the establishment of H. ephippiger as a new apex insect predator in the Americas, both in terms of ecological implications and the possible provision of ecosystem services. We also provide an additional new species record for Bonaire, Pantala hymenaea (Odonata: Libellulidae).

description: Massive exploitation of next-generation sequencing technologies requires dealing with both: huge amounts of data and complex bioinformatics pipelines. Computing architectures have evolved to deal with these problems, enabling approaches that were unfeasible years ago: accelerators and Non-Volatile Memories (NVM) are becoming widely used to enhance the most demanding workloads. However, bioinformatics workloads are usually part of bigger pipelines with different and dynamic needs in terms of resources. The introduction of Software Defined Infrastructures (SDI) for data centers provides roots to dramatically increase the efficiency in the management of infrastructures. SDI enables new ways to structure hardware resources through disaggregation, and provides new hardware composability and sharing mechanisms to deploy workloads in more flexible ways. In this paper we study a state-of-the-art genomics application, SMUFIN, aiming to address the challenges of future HPC facilities.

description: A comprehensive parameterization of the colour singlet heavy quark free energy above $T_c$ is given, using the lattice data in quenched ($N_f=0$) and unquenched ($N_f=2$ and $N_f=3$) QCD. The corresponding (temperature dependent) potentials thus obtained are then inserted into the Schrödinger equation for the charmonium and the bottomonium in the deconfined phase of QCD. The solution of the equation provides an estimate of the melting temperature and of the radii for the different $c\bar{c}$ and $b\bar{b}$ bound states.

description: Biomarkers in receptor species can be used to assess and monitor ecosystem health. This study aimed to develop mRNA biomarkers in the New Zealand triplefin Forsterygion capito and validate their induction in response to common estuarine contaminants. The targeted genes were cytochrome P450 1A (cyp1a), metallothionein (mt), vitellogenin (vtg), and cytochrome P450 aromatase (cyp19b). Fish were treated with intraperitoneal injections of benzo[a]pyrene (BaP), zinc, and 17β-oestradiol (E2). Levels of cyp1a were upregulated in the livers of fish exposed to BaP, and the vtg gene was up-regulated in male fish exposed to E2. These results indicated that these two biomarkers in F. capito can be used to assess exposure to contaminants exerting similar mechanisms of toxicity.

description: We study influence of scalar fields on Nonlinear Electrodynamics spacetimes. The investigation is carried out using both test and gravitating scalar fields. After revisiting Einstein-Maxwell scalar field solutions we focus on analytic investigation of Nonlinear Electrodynamics scalar field spacetimes, especially Square Root Lagrangian model. The main motivation being to understand whether certain specific signatures of scalar fields are preserved when Nonlinear Electrodynamics as an additional source is considered. We show that the regularity of horizon which is spoiled by scalar field in spherically symmetric static scalar-vacuum spacetimes is not improved by including Nonlinear Electrodynamics or other sources satisfying certain condition. We confirm these findings using test scalar field that enables us to go beyond spherical symmetry.

description: What are the advantages of concerns raised regarding the Cargill acquisition of Continental Grain company's grain merchandising business? The largest grain exporter acquiring the second largest exporter has raised some concerns regarding potential loss of competition, but also may make these firms with excess capacity more efficient and effective in competing for a larger U.S. share of the world market. This white paper pulls together the relevant data which was quickly available and provides some analysis which may prove useful in the dialog as the pros and cons of this acquisition are debated.

description: Vibrio parahaemolyticus and Vibrio vulnificus can be found in oysters in coastal environments. Vibrio vulnificus can induce life-threatening illness when ingested with oysters, while V. parahaemolyticus usually causes self-limiting gastroenteritis. This study investigated correlations between concentrations of these Vibrio species in Pacific oysters from eight New Zealand coastal regions (2008–2017), and seawater surface temperature (SST), salinity and rainfall. In the pooled data, most (88%) of the oyster samples were collected during summer and autumn. The prevalence of V. parahaemolyticus and V. vulnificus was 85% and 15%, respectively. Vibrio vulnificus was always detected in the presence of V. parahaemolyticus. Across all regions, V. parahaemolyticus concentration positively correlated with SST (rS  = 0.60), but not with salinity (rS  = −0.01). Vibrio vulnificus concentration weakly correlated with SST (rS  = 0.26) and salinity (rS  = −0.21). Linear and generalised additive models were investigated but none were satisfactory for prediction. Salinity and SST explained < 50% of the variability in V. parahaemolyticus concentrations, indicating that other environmental or biological factors contributed. When SST, salinity and rainfall 15 days prior to harvesting were investigated for one region, SST was the best pre-harvest indicator for elevated concentrations of both Vibrio species.

description: Planewave propagation in a simply moving, dielectric-magnetic medium that is isotropic in the co-moving reference frame, is classified into three different categories: positive-, negative-, and orthogonal-phase-velocity (PPV, NPV, and OPV). Calculations from the perspective of an observer located in a non-co-moving reference frame show that, whether the nature of planewave propagation is PPV or NPV (or OPV in the case of nondissipative mediums) depends strongly upon the magnitude and direction of that observer's velocity relative to the medium. PPV propagation is characterized by a positive real wavenumber, NPV propagation by a negative real wavenumber. OPV propagation only occurs for nondissipative mediums, but weakly dissipative mediums can support nearly OPV propagation.

description: Health, like schooling, is a form of human capital and can be expected to be positively related to labor productivity and labor supply. The production of good health and labor productivity, however, sometimes competes with an individual's lifestyle, e.g., binge drinking. In this study, an individual's health has three dimensions: current health status, binge drinking which is an unhealthy lifestyle, and stature or mature height which is a young adult's health endowment. This study presents and fits a dynamic model of an individual's demand for health, demand for binge drinking, labor supply, and wage or demand for labor equations to NLSY 1979 cohort panel data of young people. We find that binge drinking has a negative but insignificant effect on the demand for health, an individual's good health and larger stature increases his/her wage and binge drinking reduces it. An individual's good health and binge drinking increase his/her labor supply. An individual's decision to binge drinking is shown to be rational addiction which is forward looking (rather than myopic which ignore future impacts) and to be highly responsive to the price of alcohol in the long run and to the legal minimum drinking age. We also show that labor productivity of 1979 NLSY cohort is most likely 6 percent lower than earlier cohorts due to their higher frequency of binge drinking, shorter stature, and lower educational achievement.

description: The ability to understand and engineer molecular structures relies on having accurate descriptions of the energy as a function of atomic coordinates. Here we outline a new paradigm for deriving energy functions of hyperdimensional molecular systems, which involves generating data for low-dimensional systems in virtual reality (VR) to then efficiently train atomic neural networks (ANNs). This generates high quality data for specific areas of interest within the hyperdimensional space that characterizes a molecule's potential energy surface (PES). We demonstrate the utility of this approach by gathering data within VR to train ANNs on chemical reactions involving fewer than 8 heavy atoms. This strategy enables us to predict the energies of much higher-dimensional systems, e.g. containing nearly 100 atoms. Training on datasets containing only 15K geometries, this approach generates mean absolute errors around 2 kcal/mol. This represents one of the first times that an ANN-PES for a large reactive radical has been generated using such a small dataset. Our results suggest VR enables the intelligent curation of high-quality data, which accelerates the learning process.

description: We consider a nonlinear Dirichlet problem driven by the ( p , q )-Laplacian with 1 < q < p . The reaction is parametric and exhibits the competing effects of a singular term and of concave and convex nonlinearities. We are looking for positive solutions and prove a bifurcation-type theorem describing in a precise way the set of positive solutions as the parameter varies. Moreover, we show the existence of a minimal positive solution and we study it as a function of the parameter.
An integrated approach for community hazard, impact, risk and vulnerability analysis : HIRV
Creators: name: Pearce, Laurence Dominique Renée
Publisher: name: University of British Columbia
Year: 2009

description: The Great Hyogo-Ken Nanbu earthquake, Hurricane Andrew, the Lockerbie air crash, and many other disasters have had terrible impacts on communities around the world. Disasters will continue to occur, and their social, economic, political, and environmental impacts will continue to increase. Communities are becoming increasingly concerned about this and are working to develop disaster management programs to prepare for, respond to, and recover from disasters. Hazard, risk, and vulnerability (HRV) analyses form the basis of disaster management processes; unfortunately, to this point, communities and regional districts have not had access to effective HRV models. This dissertation focuses on HRV analyses that are community-based, and it argues that the goal of such analyses should be to assist communities in developing and prioritizing mitigation strategies for hazard management. It also argues that HRV models should allow for the integration of disaster management and community planning, along with a high degree of public participation. Through a literature review, fourteen key objectives for determining the adequacy of current HRV models are derived. When extant models are measured against these objectives, it becomes clear that the former are deficient in a number of areas. In order to rectify these deficiencies, a new HRV model - the hazard, impact, risk, and vulnerability (HIRV) model is introduced. The HIRV model is developed through extensive use of exploratory studies and (1) incorporates a high degree of public participation, (2) is all-hazard in scope, (3) provides for realistic and practical risk assessment, (4) establishes guidelines for determining vulnerabilities, (5) provides guidelines for determining the potential impacts of a disaster, and (6) provides a method for prioritizing mitigation strategies. The potential effectiveness of the implementation of the HIRV model is evaluated through the use of participatory case studies in the British Columbia communities of Barriere, Taylor, and Kamloops. In short, the HIRV model provides a way for communities and emergency planners to make effective use of existing resources in order to develop comprehensive and practical disaster management programs and to move towards sustainable hazard mitigation.
On Kantian tendencies during the early corona pandemic in Germany

description: Based on an ad hoc online survey about risk perception and preventive behaviours, we describe three chronological phases related to how people in Germany perceived the Corona pandemic between March 22 and May 10, 2020. In general, participants reported to be less concerned about their own risk than about the risk faced by others. However, a good portion of those who thought that they themselves were low risk actually wrote about their belief that they nevertheless had a responsibility to behave in ways that benefited others, even if it came at a cost to themselves. In loose reference to Immanuel Kant’s notion that humans have a rational duty to act in a socially responsible manner, we interpret people’s comments about other-regarding behaviour as an initiation of a Kantian tendency during the Corona pandemic. Based on these findings, we suggest that policy makers may do better in times of crisis than nudging, incentivizing, or compelling the public by law. They can perhaps accomplish more by (also) nurturing people’s innate sense of the need for socially responsible action to be taken in order to meet the daunting challenges of present and future crises.

description: This paper presents a conceptual analysis of important issues in management of agricultural research drawing on principal-agent theory and derives implications for funding and management of agricultural research. Building on well known attributes of research, whereby research results are risky, outputs are uncertain and sometimes unanticipated, more than one approach has validity for a given topic, we consider how incentives should be structured to elicit optimal research effort and directions, whether research directions should be set at a centralized or decentralized level, and the optimal duplication of effort. The results suggest that (i) the current trend toward replacement of formula funding by competitive grants allocation may be ill conceived, (ii) a mixed system with some research funding and direction at the federal level, some at the state level, and perhaps some at regional levels is advantageous, and (iii) funding of competing scientists working on the same problem at different institutions has merit.
FARM LABOR: KEY CONCEPTUAL AND MEASUREMENT ISSUES ON THE ROUTE TO BETTER FARM COST AND RETURN ESTIMATES

Publisher: name: Unknown
Year: 1996
Subjects: Labor and Human Capital

description: This paper examines methods frequently used by agricultural economists to measure the cost of farm labor, including operator and other unpaid, and to provide insights for improving them. The tradition is broken of treating labor and management separately, and labor is defined as encompassing all the productive activities of individuals or human agents used in a business, including farming. Conceptual issues are first addressed: (1) the nature of economic cost and the cost of unpaid labor and (2) time allocation in agricultural household models where an individual's annual time endowment is allocated potentially to leisure, farm work, and off-farm work. Measurement issues are addressed second: (1) specific methods for improving the measurement of the cost of farm labor and (2) specific procedures for estimating the opportunity cost of operator and unpaid farm labor. The overall goal is to obtain better farm cost and return estimates.

description: In recent years, several concerns have been raised over the threat of Strategic Lawsuits against Public Participation (SLAPP) to European democracy. This thesis explores the effects of SLAPP lawsuits both on public watchdogs as individual targets and a broader community, and how they essentially undermine democracy. The threat to democracy is explored with the analysis of freedoms and human rights that are restricted due to SLAPP effects, as well as with a single-country case study of Slovenia. Although it is maintaining a relatively high level of democracy, Slovenia has been recognized as a country under the threat of SLAPPs. For a better understanding of the effects, in-depth interviews were conducted with SLAPP victims and experts familiar with this phenomenon. Participants represented different spheres that SLAPPs in Slovenia are targeting: media, environmentalism, activism, and academia. First, the analysis focuses on the individual experiences and observations from the participants on the specifics and extent of SLAPP effects in each sphere. Then, it explores the relationship between the country’s state of democracy, recent political changes, and SLAPP cases. The analysis shows that despite the recent political shift from a right-wing government known for undemocratic actions to a left-liberal one, the threat of SLAPPs is still present. While the threat of state-led SLAPP has diminished, critical voices are still targeted by a variety of powerful actors with either political or economic goals to silence them. As emphasized by the participants, legal countermeasures are needed to tackle SLAPP lawsuits, since political changes alone will not save democracy.

description: In turbulent wall sheared thermal convection, there are three different flow regimes, depending on the relative relevance of thermal forcing and wall shear. In this paper we report the results of direct numerical simulations of such sheared Rayleigh-Bénard convection, at fixed Rayleigh number $Ra=10^6$, varying the wall Reynolds number in the range $0 \leq Re_w \leq 4000$ and Prandtl number $0.22 \leq Pr \leq 4.6$, extending our prior work by Blass et al. (2020), where $Pr$ was kept constant at unity and the thermal forcing ($Ra$) varied. We cover a wide span of bulk Richardson numbers $0.014 \leq Ri \leq 100$ and show that the Prandtl number strongly influences the morphology and dynamics of the flow structures. In particular, at fixed $Ra$ and $Re_w$, a high Prandtl number causes stronger momentum transport from the walls and therefore yields a greater impact of the wall shear on the flow structures, resulting in an increased effect of $Re_w$ on the Nusselt number. Furthermore, we analyse the thermal and kinetic boundary layer thicknesses and relate their behaviour to the resulting flow regimes. For the largest shear rates and $Pr$ numbers, we observe the emergence of a Prandtl-von Karman log-layer, signalling the onset of turbulent dynamics in the boundary layer. Finally, our results allow to extend the Grossmann-Lohse theory for heat transport in Rayleigh-Bénard convection to the sheared case, universally describing $Nu(Ra,Pr,Re_w)$.

description: We investigated whether ammonia-rich constituents are present on the surface of the Uranian moon Ariel by analyzing 32 near-infrared reflectance spectra collected over a wide range of sub-observer longitudes and latitudes. We measured the band areas and depths of a 2.2-{\micron} feature in these spectra, which has been attributed to ammonia-bearing species on other icy bodies. Ten spectra display prominent 2.2-{\micron} features with band areas and depths > 2σ. We determined the longitudinal distribution of the 2.2-{\micron} band, finding no statistically meaningful differences between Ariel's leading and trailing hemispheres, indicating that this band is distributed across Ariel's surface. We compared the band centers and shapes of the five Ariel spectra displaying the strongest 2.2-{\micron} bands to laboratory spectra of various ammonia-bearing and ammonium-bearing species, finding that the spectral signatures of the Ariel spectra are best matched by ammonia-hydrates and flash frozen ammonia-water solutions. Our analysis also revealed that four Ariel spectra display 2.24-{\micron} bands (> 2σ band areas and depths), with band centers and shapes that are best matched by ammonia ice. Because ammonia should be efficiently removed over short timescales by ultraviolet photons, cosmic rays, and charged particles trapped in Uranus' magnetosphere, the possible presence of this constituent supports geologic activity in the recent past, such as emplacement of ammonia-rich cryolavas and exposure of ammonia-rich deposits by tectonism, impact events, and mass wasting.

description: Understanding urban densities is crucial as it directly influences urban planning and sustainable development. These planning and development processes directly impact equitable resource allocation, transportation efficiency, and environmental quality. Understanding urban densities enables urban planners and policymakers to create more inclusive, equitable, livable, and resilient urban spaces that cater to the evolving needs of diverse populations. This study uses a geospatial approach influenced by Von Thünen's land use theory to examine urban densification in the Great Lakes region of the US. It applies Geographic Information Systems (GIS) to identify concentric zones extending one mile from urban centers in Michigan, Wisconsin, Illinois, Indiana, Ohio, and Pennsylvania. The study analyzes over 750 urban areas, considering population density, green space, urban infrastructure, and building heights. The population density data are sourced from a Dasymetric map provided by the EPA. Green space is mapped using a raster created from park shapefiles. Urban infrastructure is identified from impervious area raster from the NLCD dataset, and building heights are derived from GML files. This methodology reveals patterns in urban development and their implications for policymaking. It suggests prioritizing downtown densification to address urban sprawl and support environmental sustainability. The key findings were four distinct urban development clusters, each with unique characteristics: Cluster 1 included cities like Detroit and Chicago, showing potential for suburban densification around well-established infrastructure; Cluster 2 featured cities such as Champaign (mostly tier 2 cities), with opportunities for densification without compromising environmental quality; Cluster 3 encompassed cities with notable decreases in infrastructure and population densities (cities with population under 30000), indicating areas ripe for urban density increase; and Cluster 4 represents a small group of cities where densification was balanced with green space expansion. These insights inform urban planning, highlighting downtown densification's importance in countering urban sprawl and enhancing environmental sustainability in the American Great Lakes region.

description: This study focuses on re-migration, where individuals return to their place of birth after living in a new location for several years. Puerto Rican male householders, born in Puerto Rico but residing on the U.S. mainland and re-migrating to Puerto Rico, is the sample for fitting a hazard rate model of re-migration. We find a strong quadratic effect of an individual's age on his hazard rate. Also, males having English proficiency, less schooling, and working disability are less likely to re-migrate. A higher predicted job growth rate for Puerto Rico (U.S. mainland) and unemployment rate for the mainland (Puerto Rico) have positive (negative) effects on the hazard rate. The hazard rate is negatively related to the Puerto Rican real minimum wage.

description: It is well known that the category of super Lie groups (SLG) is equivalent to the category of super Harish-Chandra pairs (SHCP). Using this equivalence, we define the category of unitary representations (UR's) of a super Lie group. We give an extension of the classical inducing construction and Mackey imprimitivity theorem to this setting. We use our results to classify the irreducible unitary representations of semidirect products of super translation groups by classical Lie groups, in particular of the super Poincaré groups in arbitrary dimension. Finally we compare our results with those in the physical literature on the structure and classification of super multiplets.

description: This study examines potential long-term impacts on the U.S. and Mexican beef industries of the reduction in trade barriers under NAFTA and likely associated international technology transfers (of beef cattle, feeding methods, and meat packing) and foreign capital investments. The beef industry is represented as four subsectors: cow-calf production, post-weaning beef production, meat packing, and leather production. The analysis is accomplished through a multi-sector model of the U.S. and Mexican beef industries, estimation of key parameters, and simulation of long-run outcomes under three alternative scenarios. Our results show that Mexico will dramatically expand the size of its cow herd. The expanded supply and lower post-slaughter processing cost in Mexico give it a comparative advantage in beef production, despite most of the feed grain requirement being met from U.S. exports. Mexico is able to expand its exports of feeder calves significantly when technology is transferred and to become a beef exporter. Beef prices in both countries decrease in real terms. We conclude the U.S. beef producers cannot be optimistic about the long-run potential for beef exports to Mexico but much better prospects exist for U.S. feed grain exports.

description: This discussion outline describes the Canadian Net Income Stabilization Account (NISA) concept; provides comparisons to U.S. proposals for Farm and Ranch Risk Management (FARRM) and Individual Risk Management Accounts (IRMA); and compares these concepts to other selected policy options with respect to the counter-cyclical nature of payments and planting flexibility criteria. Staff Paper 333 embodies the discussion outline used by the author in presentation to the National Commission for 21st century Production Agriculture. The 1996 FAIR Act established the Commission to develop recommendations on future U.S. Farm Policy for the Congress and the President prior to expiration of the current farm policy.
Examining the Influence of Lake Water Quality on Visitor Sentiment: Empirical Findings from 85 US Lakes

Cultural Ecosystem Service

description: Cultural ecosystem services (CESs) are the intangible benefits that humans receive from nature, resulting from the interplay between biotic nature and abiotic nature (Gray, 2011). And very often, the intangible dimensions hold greater significance for individuals compared to material benefits (Kobryn et al., 2018). Lakes are highly valued for CESs because they provide opportunities for recreational activities, aesthetic experiences, spiritual enrichment, and reflection (Blicharska et al., 2017). Lake CESs are intricately linked to water quality, where sedimentation, nutrients, and bacteria affect people's perceptions and interactions with the water body (Keeler et al., 2012). However, our understanding of lake water quality's influence on CESs remains limited, hindering effective management strategies to enhance the economic and social values of lakes. Water-related CESs research is also constrained at broader scales (e.g., national scale) due to measurement challenges, undermining research generalizability. We hypothesized a connection between lake water quality and CESs, with water quality influencing CESs through recreational behaviors and visitor sentiment. To test this, we coupled big data from Google Review and National Lake Assessment to investigate water quality effects on CESs and visitor sentiment across 85 U.S. lake-front public parks. We implemented five analytical steps: (1) Collecting geographic data of 85 public-owned lakes and identifying lake-front parks using Google Place API, (2) Obtaining ~40,000 relevant text reviews with Python Crawler, (3) Filtering Google reviews related to lake CESs through content analysis with keyword labels, (4) Deriving positive, neutral, and negative sentiments from lake-related user-generated content using Google Cloud Natural Language API, and (5) Identifying associations between key water quality indicators and CESs-related visitor sentiment with a Bayesian multinomial model. Our results showed that CESs provided by lakes were significantly affected by multiple water quality indicators. Higher chlorophyll-a concentration and APHA color value increased negative sentiments toward lake CESs, while higher total phosphorus unexpectedly associated with increased positive CESs-related visitor experiences, possibly due to higher productivity. Our findings have implications for lake management, advocating targeted planning to promote harmony between human well-being and ecological health in lake ecosystems. Moreover, analysis of user-generated text contents for sentiment evaluation can yield valuable information regarding user satisfaction and memories of scenes, and thereby facilitate lake management practices aimed at fostering sustainable local economic development.

description: The U.S. pork production sector continues to consolidate rapidly. In the decade between 1988-1997 hog operations marketing 50,000 or more hogs a year increased their share of U.S. production from 7 to 37 percent. The share from operations marketing less than 1,000 hogs annually declined from 32 to 5 percent. However, the loss of farms beyond the very smallest category has not been as severe as typically believed. The consolidation is expected to continue as larger operations continue to be earlier adopters of technology and have taken greater steps to secure market access than have smaller farms. Fifty-seven percent of the hogs in 1997 were procured by processors outside the traditional spot market. It is estimated that the 1998 number is approximately 65 percent.

description: Spin-flip excitations in a quantum Hall electron system at fixed filling factor nu=2 are modelled and studied under conditions of a strong Coulomb interaction when the `Landau level mixing' is a dominant factor determining the excitation energy. The `one-exciton' approach used for the purely electronic excitations in question allows us to describe the Stoner transition from the unpolarized/paramgnet state to the polarized/ferromagnet one. The theoretical results are compared with the available experimental data.

Horizon Europe Programme

description: In light of the urgent need to identify concrete R&I actions to feed into the upcoming Horizon Europe Programme, the European Commission has developed an approach structured around 10 focus areas that are considered pathways with the potential to deliver impact on EU food systems transformation (European Commission, 2020). This report aims to deepen and expand the analysis of pathways areas building on the experience and results of previous activities from the FIT4FOOD2030 project, including the findings contained in the policy briefs produced by the EU Think Tank; the training modules developed by City and Policy Labs; and the previous mapping of trends, barriers, enablers & potential breakthroughs for transformation. This in-depth analysis of 10 pathway areas is one of the first European reports to include a discussion of the potential impacts of the Covid-19 pandemic – and the measures EU Member States have taken to contain it – on food systems. While the Covid-19 event is too recent to predict its full impact and produce tailored R&I recommendations to exploit its potential to accelerate the food systems transformation, the analysis produced in this report takes the current context into account. Whenever possible and appropriate, the most recent scientific evidence has been used to substantiate the arguments made in the areas researched.
