description: Poster presented by the Data Stewards from the University of Bologna (UNIBO, Alma Mater Studiorum - Università di Bologna) at the EUDAT Conference 2022 in Athens, Greece (13-15 September 2022).

Two graphical tools developed by the team are presented: 

- the “UNIBO RDM data lifecycle”, structures a series of “actions” that researchers should consider at every stage of their project.(https://doi.org/10.5281/zenodo.7249051)

- the "RDM Decisional tree" that includes the most important questions researchers should ask themselves before collecting and/or generating data, in order to follow FAIR principles while complying with all privacy/ethics/IPR requirements. (https://doi.org/10.5281/zenodo.7190005)

description: In the comment by Konig, Gefen, and Silva, their main point is to question the approximation we used in solving the Green's function. They believe that this approximative method is inappropriate to describe spin-flip-related dephasing processes caused by intradot interaction, so they believe that our conclusions are ill-founded because of that. We agree that we indeed used an approximation in calculating the Green's function. However, we believe our approximation to be reasonable and the main conclusion, namely, an intradot electron-electron interaction can not induce dephasing, should hold. In particular, we emphasize that we have taken the higher-order terms in solving the Green's function than appeared in their previous publications. We will compare the approximation used their papers with that in our work.

description: Context. Intrinsic H$α$ emission can be advantageously used to detect substellar companions because it improves contrasts in direct imaging. Characterising this emission from accreting exoplanets allows for the testing of planet formation theories. Aims. We characterise the young circumbinary planetary mass companion 2MASS J01033563-5515561 (AB)b (Delorme 1 (AB)b) through medium-resolution spectroscopy. Methods. We used the new narrow-field mode (NFM) for the MUSE integral-field spectrograph, located on the ESO Very Large Telescope, during science verification time to obtain optical spectra of Delorme 1 (AB)b. Results. We report the discovery of very strong H$α$ and H$β$ emission, accompanied by He I emission. This is consistent with an active accretion scenario. We provide accretion rate estimates obtained from several independent methods and find a likely mass of $12-15$ M$_{\rm Jup}$ for Delorme 1 (AB)b. This is also consistent with previous estimates. Conclusions. Signs of active accretion in the Delorme 1 system might indicate a younger age than the $\sim 30-40$ Myr expected from a likely membership in Tucana-Horologium (THA). Previous works have also shown the central binary to be overluminous, which gives further indication of a younger age. However, recent discoveries of active discs in relatively old ($\sim 40$ Myr), very low-mass systems suggests that ongoing accretion in Delorme 1 (AB)b might not require in and of itself that the system is younger than the age implied by its THA membership.

description: Aerobic methane oxidation is driven by both abiotic and biotic factors, which are often confounded in the soil environment. Using a laboratory-scale reciprocal inoculation experiment with two native soils (paddy and upland agricultural soils) and the gamma-irradiated fraction of these soils, we aim to disentangle and determine the relative contribution of abiotic (i.e., soil edaphic properties) and biotic (i.e., initial methanotrophic community composition) controls of methane oxidation during re-colonization. Methane uptake was appreciably higher in incubations containing gamma-irradiated paddy than upland soil despite the initial difference in the methanotrophic community composition. This suggested an overriding effect of the soil edaphic properties, which positively regulated methane oxidation. Community composition was similar in incubations with the same starting inoculum, based on quantitative and qualitative pmoA gene analyses. Thus, results suggested that the initial community composition affects the trajectory of community succession to an extent, but not at the expense of the methanotrophic activity under high methane availability. Still, methane oxidation was affected more by soil edaphic properties than by the initial composition of the methanotrophic community.

description: The rising disruptions of interdictors force supply chains’ designers to embody the protection decisions when locating the facilities. In the presence of variability in the intensity of disruptions, a risk measure is incorporated into the decision-making. The designer-interdictor bi-level problem, therefore, optimizes the joint location and protection decisions with respect to the conditional value-at-risk. This configuration has been absent from the literature. An accelerated modified Benders decomposition algorithm is developed and enhanced by being hybridized with a sample average approximation-based genetic algorithm. We examine how this new configuration influences the optimal solutions and assess the effectiveness of the proposed method.

description: Recently, an increasingly growing number of companies is focusing on achieving self-driving systems towards SAE level 3 and higher. Such systems will have much more complex capabilities than today's advanced driver assistance systems (ADAS) like adaptive cruise control and lane-keeping assistance. For complex software systems in the Web-application domain, the logical successor for Continuous Integration and Deployment (CI/CD) is known as Continuous Experimentation (CE), where product owners jointly with engineers systematically run A/B experiments on possible new features to get quantifiable data about a feature's adoption from the users. While this methodology is increasingly adopted in software-intensive companies, our study is set out to explore advantages and challenges when applying CE during the development and roll-out of functionalities required for self-driving vehicles. This paper reports about the design and results from a multiple case study that was conducted at four companies including two automotive OEMs with a long history of developing vehicles, a Tier-1 supplier, and a start-up company within the area of automated driving systems. Unanimously, all expect higher quality and fast roll-out cycles to the fleet; as major challenges, however, safety concerns next to organizational structures are mentioned.

description: The global dairy market has been adversely affected by increased milk supply in Europe, the US and the Southern hemisphere. This, amidst a reduction in demand for imported dairy commodities by China and Russia, has seen a global downturn in milk prices. New Zealand dairy farmers have been faced with depressed milk price in the last few seasons, and in response to the financial pressures, have been forced to consider farm system changes to minimise the impact. Many of the system adjustments being implemented to manage the current downturn have led to improved efficiency and are similar to those that will help farmers meet existing and proposed environmental limits being enforced by regional councils. Could the adjustments being made have lasting environmental benefits for farmers and the industry? This study aims to identify the changes in farm systems and their management as a consequence of lower milk prices, and whether these changes have improved environmental outcomes. It also aims to identify whether these outcomes are likely to last once milk price recovers, thus determining whether the current period of low milk price has a silver lining. The key adjustments made to dairy farm systems in response to low milk price were reductions in cow numbers, fertiliser use and supplementary feed use. The methodology used to determine the environmental impacts of these adjustments involved creating typical regional farms and modelling the changes experienced from a drop in milk price in Farmax and Overseer. These adjustments had subsequent impacts on milk production. The changes observed had slight implications for environmental outputs, including nitrogen leaching and greenhouse gas emissions.
Agricultural risk and remittances: the case of Uganda

description: The economic literature showed that remittances can replace missing credit and insurance markets. As a result, it is natural to expect that higher amounts of remittances will motivate agricultural farmers to engage in riskier activities. The present study aims to verify the latter hypothesis by answering three distinct questions: do households that receive higher remittances choose to cultivate a riskier crop portfolio, to engage either in crop specialization or in crop diversification and to use riskier input such as fertilizer? I use the Living Standards Measurement Study-Integrated Surveys on Agriculture (LSMS-ISA) dataset on Uganda established by the World Bank to test these hypotheses. The results show that higher remittances induce crop specialization and higher probability of fertilizer use.
Investigating the spectral characteristics of human persistent atrial fibrillation using non-contact multisite mapping: a prospective ablation study
Creators: name: Shen-Wei Chu, Gavin
Publisher: name: University of Leicester
Year: 2024

description: The electrophysiological mechanism underlying persistent atrial fibrillation (persAF) is incompletely understood and compounded by the limitations of current point-by-point mapping technologies, generating uncertainty regarding the optimal ablation strategy. Spectral mapping allows derivation of dominant frequency (DF) and regularity index (RI), which have been suggested as indicators of AF sources. The basis of the current work combines this signal processing technique with a commercially available panoramic non-contact mapping catheter in order to analyse, ablate, and further understand AF behaviour.In this clinical translational pilot study, DF maps were created from 30 seconds of continuous human persAF data via a bespoke user interface designed and implemented specifically for this work. Prospective ablation of dynamically-detected highest DF (HDF) was undertaken safely and efficaciously. Isopotential maps of HDF areas showed highly correlated focal breakout and exit but no other significant activation patterns, supportive of spatially conserved multi-layer behaviour at these areas.Using 5 minute periods of AF data, a strong inverse relationship between DF variability and RI was demonstrated. HDF and highest RI were associated with lesion ablation outcome only when cumulative effects were excluded, and AF disorganization was associated with low pre-ablation mean DF and RI.Stable DF episodes were investigated as a temporal marker of AF substrate. Such events were shown to be intermittent and spatially asynchronous but anatomically-anchored at a preferential activation rate. Consistent with our earlier findings, DF stability was found to drive periods of higher RI. These results are potentially compatible with a role for stable DF detection in identifying intermittent source behaviour in the both spatial and temporal dimensions. Stable DF difference divergence, where the same tissue could support more than one stable DF value, was related to lack of termination during substrate ablation, and may represent a novel marker of more functionally complex underlying substrate.

description: This paper presents methodological development of MAGNET, a sophisticated agricultural variant of the well-known GTAP computable general equilibrium (CGE) model for representing the Common Agricultural Policy (CAP). Using original data on EU domestic support, it examines some likely macroeconomic effects in the European Union (EU) of the expected budget over the period 2014-2020. Results suggest that agreed budget cuts, in constant price, have limited impacts on EU and world markets, given the broadly non-distortive representation of present CAP policy.

description: The impact of policy scenarios on economic welfare and the environment depends to a large extent on their direct effect on land use: a strong increase in the cultivation of legumes means a significant environmental impact and a sizeable impact on other variables such as farmers’ incomes, cost to taxpayers and imports and exports. The impact of realistic policy alternatives aimed at promoting legumes is likely to be limited. In particular, they may not be able to reverse the trend in the decline of grain legumes.

However, the standard treatment of production function in AGE models is not completely satisfactory. It is commonly based on nested CES functions that are rigid and empirically hard to estimate. In this paper, I will show that by applying a more general functional form - CRESH - the agricultural sector can be presented more realistically in AGE models.
Limit theorems for the 'laziest' minimal random walk model of elephant type

description: We consider a minimal model of one-dimensional discrete-time random walk with step-reinforcement, introduced by Harbola, Kumar, and Lindenberg (2014): The walker can move forward (never backward), or remain at rest. For each $n=1,2,\cdots$, a random time $U_n$ between $1$ and $n$ is chosen uniformly, and if the walker moved forward [resp. remained at rest] at time $U_n$, then at time $n+1$ it can move forward with probability $p$ [resp. $q$], or with probability $1-p$ [resp. $1-q$] it remains at its present position. For the case $q>0$, several limit theorems are obtained by Coletti, Gava, and de Lima (2019). In this paper we prove limit theorems for the case $q=0$, where the walker can exhibit all three forms of asymptotic behavior as $p$ is varied. As a byproduct, we obtain limit theorems for the cluster size of the root in percolation on uniform random recursive trees.

description: In 1940, Luis Santaló proved a Helly-type theorem for line transversals to boxes in R^d. An analysis of his proof reveals a convexity structure for ascending lines in R^d that is isomorphic to the ordinary notion of convexity in a convex subset of R^{2d-2}. This isomorphism is through a Cremona transformation on the Grassmannian of lines in P^d, which enables a precise description of the convex hull and affine span of up to d ascending lines: the lines in such an affine span turn out to be the rulings of certain classical determinantal varieties. Finally, we relate Cremona convexity to a new convexity structure that we call frame convexity, which extends to arbitrary-dimensional flats.

We focus on studies that examine stakeholder preferences and provide relative weights for the economic, social and environmental dimensions of sustainability. Descriptive and meta-analysis are used to evaluate the 34 identified studies. The findings show the equal importance of the economic, social and environmental objectives of agriculture, but also that the general public emphasizes social values, while economic considerations are highlighted in nation-wide studies. Of the environmental objectives, those pertaining to sustainable resource management have received most weight.
title: Functional Identification of MicroRNAs Counteracting Cellular Senescence
Creators: name: Ring, Nadja Anneliese Ruth
Publisher: name: The Open University
Year: 2017

description: Cellular senescence is a process closely linked to organismal ageing, and clearance of senescent cells has been shown to revert aspects of the ageing phenotype. We sought to identify miRNAs able to counteract replicative senescence at the cellular level, and investigate their effect in vivo. A library of 879 human miRNAs mimics was used for a high throughput screen using high content microscopy to search for miRNAs able to restore a high replicative phenotype in WI-38 human diploid fibroblasts exhibiting replicative senescence. Screening endpoints were the analysis of the incorporation of the nucleotide analogue EdU, as a measure of cell proliferation, and the level of the cell cycle kinase inhibitor p21 as an indicator of G1 cell cycle arrest. Twenty miRNAs were identified that exerted a strong replicative effect on senescent cells (up to 40% EdU-positive cells compared to a basal incorporation of <10%) while markedly reducing p21 levels. Cells treated with these miRNAs had decreased expression of p16 and senescence-associated beta galactosidase. Importantly, all of the identified miRNAs were capable of exerting their pro-proliferative action even in the absence of serum stimulation. Three miRNAs - hsa-miR-523-3p, hsa-miR-639, and hsa-let-7i-3p - were selected for deep-transcriptomic sequencing, to identify putative miRNA targets. CDKN1A and GRIN3B were identified as possible targets, while the mTOR pathway was observed to be necessary for miRNA induced proliferation. Finally, miR-523-3p and let-7i-3p were administered in vivo in aged mice to assess their effect on sarcopenia. The identified miRNAs provide important information on the molecular mechanisms underlying cellular senescence and with further research may constitute a new class of nucleic acid therapeutics to combat tissue degeneration in ageing.

description: Employing correlation analysis, we investigate whether rural development in the EU countries is associated with their institutional quality represented by “good” governance indicators of the World Bank (voice and accountability, political stability, government effectiveness, regulatory quality, control of corruption). Generally, our results provide empirical support for the view that better nation-state governance goes hand in hand with better performance of rural economy and show that in new member states those relationships, in many cases, are stronger than in the oldest ones. Improving government quality in new member states would help their rural areas to achieve better convergence with the EU-15.

The study contributes to the literature on rural entrepreneurship and the role of institutional factors as drivers of entrepreneurial decisions. Using primary farm household data from Bulgaria and relying on Ajzen's Theory of Planned Behavior, we tested the mediation effects of corruption perceptions over attitudes, norms and perceived control. Evidence for partial mediation through attitudes was found. Stronger corruption perception is correlated with both stronger start-up intentions and positive attitudes towards it.

description: A new technique to derive delay models from systems of partial differential equations, based on the Mori-Zwanzig formalism, is used to derive a delay difference equation model for the Atlantic Multidecadal Oscillation. The Mori-Zwanzig formalism gives a rewriting of the original system of equations which contains a memory term. This memory term can be related to a delay term in a resulting delay equation. Here the technique is applied to an idealized, but spatially extended, model of the Atlantic Multidecadal Oscillation. The resulting delay difference model is of a different type than the delay differential model which has been used to describe the El Niño- Southern Oscillation. In addition to this model, which can also be obtained by integration along characteristics, error terms for a smoothing approximation of the model have been derived from the Mori-Zwanzig formalism. Our new method of deriving delay models from spatially extended models has a large potential to use delay models to study a range of climate variability phenomena.

Designing social interactions with animated avatars and speech output for Product Recommendation Agents in electronic commerce
Creators: name: Qiu, Lingyun
Publisher: name: University of British Columbia
Year: 2010

description: Product Recommendation Agents (PRAs) and other web-based decision aids are deployed extensively by online vendors, to provide virtual advising services to their customers. While the design of PRA functionality has received increasing amount of attention in academic studies, the social aspects of human-PRA interactions are comparatively less studied. This dissertation investigates the potential of enhancing users’ social experiences with PRAs by developing and analyzing an anthropomorphic interface, which has humanoid embodiment and voice output. This dissertation first investigates the importance of choosing appropriate demographic embodiments for a humanoid PRA. The two demographic variables that have been assessed are ethnicity and gender. As suggested by similarity-attraction theories and social-identity theories, results of a laboratory experiment have revealed that users apply similar social stereotypes in human-human communications as they apply to evaluate humanoid agents. PRAs that match the ethnicity of users are perceived by the users as more sociable, more competent, and more enjoyable to interact with than PRAs that do not match users’ ethnicity; as well, same-gender PRAs are perceived as more competent and more honest than opposite-gender agents. In addition, the "match-up" effects of ethnicity appear to be more significant among female users than among males. Two interface components are also empirically investigated in this dissertation: (1) presence of a humanoid embodiment and (2) output modalities (text, computer-synthesized voice, or human voice). Results from a laboratory experiment demonstrate that humanoid embodiments increase consumers’ perception of a PRA’s social presence, their beliefs in its competence, and the enjoyment they derive from interaction with the PRA. A human voice also appears to be significantly more effective than on-screen text and computer-synthesized voice in improving the PRA’s perceived social presence and enjoyment. Furthermore, the important role of social relationships in influencing user adoption of agents is tested by integrating social presence, trust , and perceived enjoyment with the Technology Acceptance Model (TAM). Social presence appears to be a common antecedent of both trust and perceived enjoyment. Trust exerts a direct impact on user intentions to adopt PRAs, as well as an indirect impact via user perceptions of PRAs’ usefulness. Perceived enjoyment also influences adoption intentions through perceived usefulness and perceived ease of use.

Simple statistical physics describe well the distribution of hot nuclei at breakup, provided the surface symmetry term in the free energy is much smaller at high excitation than in ground state nuclei. This result may reflect the condition of low density and finite temperature when these systems disassemble.

description: Private food safety standards (PFSS) are widely adopted by firms in the agri-food system, as they meet an increasing consumer demand for safety and quality. Yet, recent economic literature found that PFSS might serve other purposes than just ensuring food safety. Our paper contributes to this literature, framing PFSS within a contract-theory model. We conclude that PFSS can be used to lower the coordination costs along the supply chain and that their effects go beyond ensuring the production of quality and safety attributes. The model shows that PFSS can reduce the cost of solving moral hazard problems for non-discriminating buyers facing heterogeneous suppliers.

description: We have used the velocity dispersion as an age indicator to constrain the ages of a large sample of main sequence Vega-like stars in order to study the lifetimes and temporal evolution of the dust disks around them. We use HIPPARCOS measurements to compute stellar velocities in the sky plane. The velocity dispersion of Vega-like stars is found to be systematically smaller than that of the normal main sequence field stars for all spectral types, suggesting that the main sequence dusty systems, on average, are younger than normal field stars. The debris disks seem to survive longer around late type stars as compared to early type stars. Further, we find a strong correlation between fractional dust luminosity ((f_{d} \equiv L_{dust}/L_{\star})) and velocity dispersion of stars with dust disks. Fractional dust luminosity is found to drop off steadily with increasing stellar age from early pre-main sequence phase to late main sequence phase.

subject: regulatory heterogeneity

description: The purpose of this paper is to assess the extent of asynchronicity in the authorisations of new genetically modified organism (GMO) events between importing and exporting countries. Based on the literature, we systemise the GMO regulatory framework and use dissimilarity and stringency indices to assess the regulatory differences. The results show an increase in the asynchronous approval across the majority of country pairs. However, focusing only on commercialised events and considering only regulatory differences in which the importers are more stringent than the exporters, the asynchronous approval is considerably lower, and the result indicates that the major trade leaders have synchronised their approval status for GMOs over time.

title: How Academics See The Benefits And Challenges Of Business Ethics Teaching: Some Views From A UK Business School
Creators: name: Tonthat, Ai-Quang

description: The UN Principles of Responsible Management Education (PRME) initiative was launched at the same time as the global financial crisis was unfolding. This has highlighted the pressing need to teach business ethics in business schools around the world and has intensified the effort to have teaching business ethics institutionalised, a strategy which many scholars have called for over the years (De George 1987, Etzioni 1991, Donaldson 2014). Despite the development of business ethics over four decades as an academic field, the benefits and challenges of teaching business ethics are still evolving unclear? This qualitative study, conducted on a small scale, has found that some of the issues such as the importance of teaching business ethics or its benefits are no longer on the front line of debates as they have been well accepted, but issues such as the conceptualisation of business ethics and how business ethics should be taught remain very topical. Blending with these are some new benefits and challenges presented by the multi-cultural environment of internationalisation, requiring a concerted effort from both institutional and faculty levels.
Non-Extreme Black Holes from D-branes at Angles

description: We construct the non-extreme solutions of non-orthogonal intersecting D-branes. The solutions reduce to non-extreme black holes upon the toroidal compactification. We clarify the relation between two configurations with equal mass and charge, one of which is non-orthogonal intersecting D-branes and the other one is orthogonal D-branes, from supergravity and string theory perspective. We also calculate mass and entropies for these black holes.

description: Effects of dynamical activity spillover in a noisy binary choice game (Ising game) on a complete graph are studied. Binary choice games are very important for both economics and statistical physics playing a role of the bridge between these two fields. In this paper we investigate the effects of self-excited activity induced by activity spillover on relaxation to equilibria and transitions between metastable equilibria at finite times. Using the formalism of master equations we show that both relaxation and interequilibria transitions at finite time are accelerated by the effects of activity spillover.

Two-proton small-angle correlations in central heavy-ion collisions: a beam-energy and system-size dependent study
Creators: name: Kotte, R.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Nuclear Experiment (nucl-ex)

description: Small-angle correlations of pairs of protons emitted in central collisions of Ca + Ca, Ru + Ru and Au + Au at beam energies from 400 to 1500 MeV per nucleon are investigated with the FOPI detector system at SIS/GSI Darmstadt. Dependences on system size and beam energy are presented which extend the experimental data basis of pp correlations in the SIS energy range substantially. The size of the proton-emitting source is estimated by comparing the experimental data with the output of a final-state interaction model which utilizes either static Gaussian sources or the one-body phase-space distribution of protons provided by the BUU transport approach. The trends in the experimental data, i.e. system-size and beam energy dependences, are well reproduced by this hybrid model. However, the pp correlation function is found rather insensitive to the stiffness of the equation of state entering the transport model calculations.

Letter from 1918 addressed to James Jaybee Joyce of the Royal West Kent Regiment of the 6th Battalion from King George.

Joyce served in France on the Western Front.

The letter refers to time at Dulmen Camp after he was captured in November 1917.

Family story that he escaped POW camp on Dutch border. They were often brought out of the camp during the war. Dutch family took him in and he returned at the end of the war.

Joyce was 20 when he enlisted. DOB: 30/06/1897. He died in the 1960s.

Pamela Humphreys (James' wife) said he was very reserved after the war. Had lung problems maybe due to mining.

Survived the war but injured by POW camp.

Captured at Battle of Cambrai 30/11/1917.

Lived in Brixton, London.

Letter says he was ''released'' from POW camp but the story is he escaped, and helped others out too.

Known to have fought at Le Quesnoy.

He is the great-grandfather of the contributor.
Probing The Multiphase Interstellar Medium Of The Dwarf Starburst Galaxy NGC 625 With FUSE Spectroscopy

description: We present new FUSE spectroscopy of the dwarf starburst galaxy NGC 625. These observations probe multiple phases of the interstellar medium, including the coronal, ionized, neutral and molecular gas. This nearby (D = 3.9 +/- 0.2 Mpc) system shows a clear detection of outflowing coronal gas as traced by OVI 1032 Angstrom absorption. The centroid of the OVI profile is blueshifted with respect to the galaxy systemic velocity by ~ 30 km/sec, suggesting a low-velocity outflow. The implied OVI velocity extent is found to be 100 +/- 20 km/sec, which is fully consistent with the detected HI outflow velocity found in radio synthesis observations. We detect multiple lines of diffuse H2 absorption from the ISM of NGC 625; this is one of only a few extragalactic systems with FUSE detections of H2 lines in the Lyman and Werner bands. We find a potential abundance offset between the neutral and nebular gas that exceeds the errors on the derived column densities. Since such an offset has been found in multiple dwarf galaxies, we discuss the implications of a lower-metallicity halo surrounding the central star forming regions of dwarf galaxies. The apparent offset may be due to saturation of the observed OI line, and higher S/N observations are required to resolve this issue.
