title: Responsibility for climate change: collective harm, individual accountability and radical moral revisionism
Creators: name: Francis, Bennet
Publisher: name: University of Reading
Year: 2023

description: Climate change is an instance of the problem of collective impact. This is a problem in normative ethics, which arises when the actions of many individuals together produce some morally significant outcome, but no agent is apparently an appropriate object of accountability for it. Given climate change is a disastrous, agent-caused, foreseen harmful outcome, many people share the judgment that some agent or agents ought to be accoXnWable foU WhaW haUm, \eW no indiYidXal·V behaYioXU iV appaUenWl\ of VXfficienW moUal significance for assignments of accountability, and corresponding assignments of remedial duty, to be appropriate. The problem has led some theorists to the drastic conclusion that our existing moral concepts are fundamentally unsuited to the complex global structure of interpersonal relations in which we today find ourselves, and that we therefore need to create radically new moral concepts. The thesis offers a critical taxonomy of responses to the problem in the existing literature, before focusing on three very different types of response: defences of individual direct duties to reduce personal emissions, defences of participatory duties grounded in minimal forms of shared agency, and radical moral revisionism about the content of our individual duties. While the first of these kinds of response fail, the thesis develops and defends a version of the second, based on the idea of quasi-participatory accountability. This is the sense in which individuals can be accountable for the outcomes associated with group behaviours when those individuals identify with those behaviours and regard themselves as participating in collective action, even in circumstances when there is no actual coordination between individual agents. The thesis argues that the radical revisionist approach relies on a deeply flawed understanding of the philosopher's role in influencing moral attitudes. It is therefore an approach based on quasi-participatory accountability renders radical revisionism unnecessary.
Duality mapping and unbinding transitions of semiflexible and directed polymers

description: Directed polymers (strings) and semiflexible polymers (filaments) are one-dimensional objects governed by tension and bending energy, respectively. They undergo unbinding transitions in the presence of a short-range attractive potential. Using transfer matrix methods we establish a duality mapping for filaments and strings between the restricted partition sums in the absence and the presence of a short-range attraction. This allows us to obtain exact results for the critical exponents related to the unbinding transition, the transition point and transition order.

Fisheries gear and biological context drive fishing-related incidental mortality in Pacific salmon spawning migrations
Creators: name: Bass, Arthur
Publisher: name: University of British Columbia
Year: 2018

description: Most fisheries inadvertently capture non-target fish species or populations. In addition, fish may interact with and escape fishing gears without being observed. Regardless of whether fish are released or escape, negative impacts from interacting with fishing gears (including stress and injury) may lead to fishing-related incidental mortality (FRIM). However, FRIM is typically difficult to observe and therefore is not easily or well quantified. Further, FRIM is contingent on many biological and environmental factors, which have received little consideration in fisheries management. Specifically, infectious disease is expected to mediate FRIM, but has been studied little in this context. Because of their life histories, Pacific salmon are both particularly vulnerable to FRIM and ideal model animals for its study. This dissertation sought to further the knowledge regarding FRIM in Pacific salmon during their freshwater spawning migrations by conducting in situ studies of capture methods and pertinent biological factors. Salmon received radio-frequency tags following exposure to fisheries gear so that migration survival could be determined. Quantitative PCR was performed on non-lethal biopsies to determine the presence and load of infectious agents, as well as immune system function. Sockeye salmon escaping or released from gillnets experienced elevated FRIM, slowed migration, and reduced spawning success. Although the impact of gears was consistent between years, the incidence of FRIM was reduced for mature fish. The high impact of severe injuries was indicated by low migration survival and the elevated expression of acute phase response genes. Mature Chinook salmon with infections of a blood-borne protozoan parasite experienced elevated mortality, regardless of a simulated fisheries gear exposure. My dissertation indicates that salmon interacting with gillnets in freshwater experience significant FRIM, but biological factors can override these impacts. Future research should seek to estimate the rate of gillnet escapes, identify gears that minimize physical damage, localize the time in migrations when maturity confers resilience, and use repeated sampling to better define the role of infectious agents in FRIM. Fisheries managers could reduce FRIM by prioritizing lower impact gears, promoting fisheries in locations where salmon are more mature and pathogens are sparse, and conducting regular monitoring of infectious agents.
The One and the Many: A Contemporary Thomistic Metaphysics
Creators: name: Clarke, S.J., W. Norris
Publisher: name: University of Notre Dame
Year: 2023

description: When it is taught today, metaphysics is often presented as a fragmented view of philosophy that ignores the fundamental issues of its classical precedents. Eschewing these postmodern approaches, W. Norris Clarke finds an integrated vision of reality in the wisdom of Aquinas and here offers a contemporary version of systematic metaphysics in the Thomistic tradition. The One and the Many presents metaphysics as an integrated whole which draws on Aquinas' themes, structure, and insight without attempting to summarize his work. Although its primary inspiration is the philosophy of St. Thomas himself, it also takes into account significant contributions not only of later philosophers but also of those developments in modern science that have philosophical bearing, from the Big Bang to evolution.\u000a\u000a\u00A9 University of Notre Dame\u000a\u000aCopyright for most content is held by The University of Notre Dame.

title: Setting the scope of climate justice: the intergenerational challenge
Creators: name: Luzzatto, Livia Ester
Publisher: name: University of Reading
Year: 2023

description: Climate change poses questions of intergenerational justice, but some of its features make it difficult to determine whether we have obligations of climate justice to future generations, and if so why. Yet despite these challenges, there are reasons – including the predicted severity of future climate impacts – to think we have intergenerational duties of climate justice. This thesis develops an account of the scope of climate justice which shows that we have intergenerational obligations because many of our actions are based on presuppositions about future people. When agents engage in such intergenerational actions, they acquire an obligation to also recognise those future people as agents within their principles of justice, and with that a duty to respect their agency and autonomy. As most collective agents relevant to climate justice – who are the focus of this thesis – engage in intergenerational actions, this account grounds wideranging obligations of climate justice to future generations. The proposed approach is able to overcome the intergenerational challenges of climate change because it meets what I argue are three necessary criteria: it provides ways to cope with uncertainty, is able to deal with the complexity of climate change, and includes future people for their own sake. It meets these criteria by adopting an action-centred methodology that grounds our obligations of justice on the presuppositions of activity. Existing accounts of climate justice, on the other hand, have often paid little attention to justifying its intergenerational scope. This has left them vulnerable to objections like the non-identity problem and the non-existence challenge. The proposed account offers a way to circumvent those challenges and provides a robust basis for subsequent substantive accounts of intergenerational climate justice. In this way, it facilitates a theoretically sound and more forceful response to the urgent challenge of climate change.

description: A Beauville surface is a rigid complex surface of the form (C1 x C2)/G, where C1 and C2 are non-singular, projective, higher genus curves, and G is a finite group acting freely on the product. Bauer, Catanese, and Grunewald conjectured that every finite simple group G, with the exception of A5, gives rise to such a surface. We prove that this is so for almost all finite simple groups (i.e., with at most finitely many exceptions). The proof makes use of the structure theory of finite simple groups, probability theory, and character estimates.

description: Stoichiometric constraints play a role in the dynamics of natural populations, but are not explicitly considered in most mathematical models. Recent theoretical works suggest that these constraints can have a significant impact and should not be neglected. However, it is not yet resolved how stoichiometry should be integrated in population dynamical models, as different modeling approaches are found to yield qualitatively different results. Here we investigate a unifying framework that reveals the differences and commonalities between previously proposed models for producer-grazer systems. Our analysis reveals that stoichiometric constraints affect the dynamics mainly by increasing the intraspecific competition between producers and by introducing a variable biomass conversion efficiency. The intraspecific competition has a strongly stabilizing effect on the system, whereas the variable conversion efficiency resulting from a variable food quality is the main determinant for the nature of the instability once destabilization occurs. Only if the food quality is high an oscillatory instability, as in the classical paradox of enrichment, can occur. While the generalized model reveals that the generic insights remain valid in a large class of models, we show that other details such as the specific sequence of bifurcations encountered in enrichment scenarios can depend sensitively on assumptions made in modeling stoichiometric constraints.

description: Several studies document that skills are strong predictors of earnings; however, less is known about the extent to which labour market size influences the return to skills. Using data from a unique representative survey recording the skill requirements of Hungarian firms, we show that social skills have higher returns in large urban labour markets. Surprisingly, this pattern cannot be observed for cognitive skills, while the return to manual skills slightly decreases with labour market size. Our estimates are robust to different agglomeration measures, additional controls and estimation methods; however, returns to skills seem to vary considerably across worker groups.

description: Vision-language-action models (VLAs) have shown potential in leveraging pretrained vision-language models and diverse robot demonstrations for learning generalizable sensorimotor control. While this paradigm effectively utilizes large-scale data from both robotic and non-robotic sources, current VLAs primarily focus on direct input--output mappings, lacking the intermediate reasoning steps crucial for complex manipulation tasks. As a result, existing VLAs lack temporal planning or reasoning capabilities. In this paper, we introduce a method that incorporates explicit visual chain-of-thought (CoT) reasoning into vision-language-action models (VLAs) by predicting future image frames autoregressively as visual goals before generating a short action sequence to achieve these goals. We introduce CoT-VLA, a state-of-the-art 7B VLA that can understand and generate visual and action tokens. Our experimental results demonstrate that CoT-VLA achieves strong performance, outperforming the state-of-the-art VLA model by 17% in real-world manipulation tasks and 6% in simulation benchmarks.

description: Zinc-ion batteries are promising alternatives to lithium-ion batteries, offering advantages in safety, cost, and environmental impact. However, their performance is often limited by the functioning of the zinc anode. This study employs severe plastic deformation via the high-pressure torsion (HPT) method to enhance the electrochemical performance of zinc anodes. HPT reduced the grain size from >1000 μm to 20 μm and introduced a (002) basal texture. The battery assembled with HPT-processed zinc demonstrated improved cycling stability, rate performance, and specific discharge capacity (>500 mAh/g at 0.5 A/g after 50 cycles), particularly at high current densities. This performance enhancement was attributed to grain-boundary and texture effects on improved ion transfer (confirmed by electrochemical impedance spectroscopy), fast redox reaction kinetics (confirmed by cyclic voltammetry), and reduced corrosion (confirmed by microscopy and potentiodynamic polarization test). This study highlights the potential of severely deformed materials with textured fine grains for advanced rechargeable battery technologies.

description: The necessary social distancing to limit the spread of COVID-19 during the recent pandemic implies that regions with higher essentiality and teleworking levels have lower vulnerability to poverty and inequality, the opposite occurring in regions intensive in closed activities. Using the latest 2020 European Union Statistics on Income and Living Conditions, we estimate that in the absence of compensating measures, this shock can result in sizable but unequal increases in poverty (between 8.3 and 20.7 percentage points (p.p.)) and wage inequality (between 2.6 and 6.0 Gini points) across Spanish regions. Moreover, inequality between regions can rise, which would erode regional cohesion in Spain.

description: In this work, the four high entropy CoCrFeNiX alloys (X=Mo,Nb,B,Si) were prepared by induction melting to comparatively analyse their structure, nanomechanical properties, and corrosion resistance in the chloride ion environment. The CoCrFeNiNb and CoCrFeNiMo alloys are composed of FCC solid solution and intermetallic phases (TM)2Nb and Cr-Mo-TM. In the case of the CoCrFeNiB alloy, a complex phase structure was revealed, consisting of FCC solid solution and three types of borides. In turn, the addition of Si substantially altered the phase composition of the CoCrFeNi alloy, resulting in the formation of two intermetallic phases. The corrosion behaviour of the alloys was studied in 3.5 and 5% NaCl solutions. The highest corrosion resistance in both solutions used characterize the CoCrFeNiSi alloy, showing the lowest corrosion current density and the most positive corrosion potential values. For measurements in 5% NaCl solution, icorr and Ecorr were equal to 0.24 microA/cm2 and -0.136 V. Currently, the least favourable corrosion parameters were recorded for the CoCrFeNiMo alloy. The results of EIS measurements confirmed the high protective abilities of passive film formed on the CoCrFeNiSi alloy surface. The highest strength properties were shown by the alloys with the addition of metalloids. For the CoCrFeNiSi alloy, the highest nanohardness value was obtained (above 15 GPa), while the CoCrFeNiB showed the highest Young modulus (above 275 GPa).

Similarity measure and its usage for document retrieval and ranking.

In this work, our research goal is an expert system for job placement, based on skills, capabilities, areas of expertise, present in someone's curriculum vitae and personal preferences. The challenge is to take into account all the personal educational experiences (formal, informal, and on-the-job), but also work-related know-how, to create a concept based on the person. This will allow a reasoned matching process with existing job positions, but also towards additional educational experience for profile improvement.

Taking inspiration from the explicit semantic analysis (ESA), we developed a domain-specific approach to semantically characterize documents and compare them to similarity.

Thanks to an enriching and a filtering process, we transform the general purpose

The domain is as defined as a German knowledge base for educational experiences and for job offers.

Initial testing with a small set of documents. There are still issues that we would like to tackle in the next project steps.

Alongside, we have other research directions. We are going to take a look into the account of the theory for the optimization of our solution to a multi-lingual context.

title: Studies toward the synthesis of stemodinone
Creators: name: Sani, Abubakar
Publisher: name: University of Reading
Year: 2021

description: Stemodinone 1, the principal target of the work in this thesis, is a naturally occurring tetracyclic diterpene isolated from the leaves of Stemodia maritima L. (Schrophulariaceae) and used for the treatment of venereal disease. The reported medicinal properties of stemodinone and its analogous compounds such as aphidicolin 2 attracted the attention of organic chemists to the investigation of the complex structure of the compound. The recently described trigoheterone A 3 (Figure 1) has shown significant inhibitory effect towards five cancer cell lines (SW480, HL-60, A549, SMMC-7721 and MCF-7) with IC50 values similar to the cisplatin. From a synthetic viewpoint, preparing the quaternary spiro centre at C9 is complicated by it being adjacent to a second quaternary carbon: a very hindered environment (Figure 1): carbons 9 and 10, highlighted in red). The present work is part of a programme to develop a synthesis of stemodinone 1 that is based upon an intramolecular alkene-arene meta-photocycloaddition. The most advanced example of this type being the conversion of 4 into synthetic intermediate 5. In particular, the adjacent quaternary centres in 5 (highlighted in red) have been formed by the cycloaddition of sp2 hybridised carbon atoms, one component of which is a benzene ring excited to its first singlet excited state (S1). Previous work by Boyd and Chappell established a synthetic route for the preparation of the photocycloaddition precursor 4, beginning from the commercially available starting material dimedone, which has the gem-dimethyl group present on the A-ring of stemodinone 1. However, the synthesis of 4 contains a conjugate addition of an aryl cuprate that proceeds in, at best, 15% yield. Described in the present work is an effort to address an improved synthesis of 4 utilising a Schultz heteroatom-directed photoarylation e.g. 6 to 7 (Scheme 2). Specifically, with the aim of improving the preparation of the quaternary centre in 4 adjacent to the aromatic ring. The general value of generating highly hindered quaternary carbons by the combination of sp2 carbons via their -faces has been illustrated above. Schultz has demonstrated that this class of photoarylation is able to facilitate the synthesis of quaternary centres in the lycoramine and morphine skeletons. iii Set out below is a disconnection of stemodinone 1 that uses both the arene-alkene metaphotocycloaddition and a Schultz heteroatom-directed photoarylation, leading back to dimedone (Scheme 3). In this thesis, an examination of the Schultz cyclisation toward stemodinone is reported, with both sulfur and oxygen linking atoms. The potential value of flow photochemistry methods, as compared to batch photolysis, is also examined.

Experimental and computational study of an air-breathing micro liquid fuel cell with an extended active anode catalyst region
Creators: name: Zhang, Yinghui
Publisher: name: University of British Columbia
Year: 2019

description: Portable electronic devices for the next generation demand a quick charging and long-lasting energy power system. Micro direct methanol fuel cells (µDMFCs) are considered as one of the appropriate alternatives to rechargeable battery technology for portable power devices. Although a significant amount of work has been done with µDMFCs, it is still a design challenge to miniaturize the fuel cell and to provide adequate power. The conventional bipolar fuel cell architecture contains a membrane electrode assembly sandwiched between two flow field plates. In this research, we present an approach to enhance the maximum power density of µDMFCs without affecting the total fuel cell volume by depositing extra anode catalyst on the fuel flow channel walls. An air-breathing µDMFC with extra anode catalyst deposited on the channel walls was developed, and the effects of key design parameters and operating conditions on the fuel cell performance were examined by measuring the overall cell and individual electrode polarization curves. The fuel cell with extra anode catalyst on the channel walls improved the maximum power density by 20% compared to the conventional design with only a catalyst coated membrane. The fuel cell design approach with catalyzed flow field channel walls was also demonstrated in an air-breathing micro Fe(II)/Fe(III) redox anode fuel cell (μRAFC). The μRAFC with graphite channel walls as an anode improved the maximum power density by 281% compared to the μRAFC with inactive channel walls. The impacts of key operating conditions on the cell performance were also evaluated. A 3D simplified model for the µDMFC design with catalyzed channel walls was developed and applied to evaluate the key parameters. It was found that the fuel cell performance was mainly limited by the kinetics of the methanol oxidation reaction. For the fuel cell with anode catalyst both on the membrane and the channel walls, increasing the anode catalyst loading on the channel walls improved the contribution of the anode on the wall to the total anodic current, and reducing the channel dimensions only slightly improved the cell performance.

description: This study analyses whether the efficiency of Ecuadorian public hospitals experiences spatial dependence. We investigate whether demand variations have affected public hospitals’ efficiency performance through direct and spillover effects since the adoption of the current constitution in 2008. Our analysis exploits an innovative two-stage approach to estimate hospital efficiency in the first stage and then applies a spatial econometric framework to disentangle direct and spillover effects in the second. The results confirm positive spatial interactions among public hospitals’ efficiency, as well as positive direct and spillover effects coming from demand increases, which have been reinforced since 2008.

description: The potential energy surfaces of even-even $^{142-156}$Ba are investigated in the constrained reflection-asymmetric relativistic mean-field approach with parameter set PK1. It is shown that for the ground states, $^{142}$Ba is near spherical,$^{156}$Ba well quadrupole-deformed, and in between $^{144-154}$Ba octupole deformed. In particular, the nuclei $^{148,150}$Ba with $N=92,94$ have the largest octupole deformations. By including the octupole degree of freedom, energy gaps $N=88$, $N=94$ and $Z=56$ near Fermi surfaces for the single-particle levels in $^{148}$Ba with $β_2\sim 0.26$ and $β_3\sim 0.17$ are found. Furthermore, the performance of the octupole deformation driving pairs ($ν2f_{7/2}$, $ν1i_{13/2}$) and ($π2d_{5/2}$, $π1h_{11/2}$) is demonstrated by analyzing the single-particle levels near Fermi surfaces in $^{148}$Ba.

Electoral strategies in multilevel systems: the effect of national politics on regional elections

description: Elections are at the heart of representative democracies. Whereas the study of national elections is a prominent field in comparative politics, we still know little about subnational political actors’ behaviour. We seek to close this gap by applying a dictionary coding approach to analyse parties’ issue-based content of 743 subnational manifestos in Austria and Germany. We show that subnational parties emphasize regional topics less if regional elections happen close to national elections but focus more on both regional and mixed topics if their national party organization is in government. This has important implications for electoral competition in multilevel systems.
Dynamics of solutions of the Einstein equations with twisted Gowdy symmetry

subject: FOS: Physical sciences

description: Some of the most interesting results on the global dynamics of solutions of the vacuum Einstein equations concern the Gowdy spacetimes whose spatial topology is that of a three-dimensional torus. In this paper certain of these ideas are extended to a wider class of vacuum spacetimes where the spatial topology is that of a non-trivial torus bundle over a circle. Compared to the case of the torus these are topologically twisted. They include inhomogeneous generalizations of the spatially homogeneous vacuum spacetimes of Bianchi types II and VI${}_0$. Using similar procedures it is shown that the vacuum solutions of Bianchi type VII${}_0$ are isometric to a class of Gowdy spacetimes, the circular loop spacetimes, thus establishing links between results in the literature which were not previously known to be related to each other.

description: We predict that spin-waves in an easy-plane ferromagnet have a finite lifetime at zero temperature due to spontaneous decays. In zero field the damping is determined by three-magnon decay processes, whereas decays in the two-particle channel dominate in a transverse magnetic field. Explicit calculations of the magnon damping are performed in the framework of the spin-wave theory for the $XXZ$ square-lattice ferromagnet with an anisotropy parameter $λ<1$. In zero magnetic field the decays occur for $λ^*

description: Today, the information and telecommunications infrastructure (hereinafter - ICT) is coming to the fore, which is becoming the most important element of economic development. It is impossible to consolidate the state in the world economic and information space without modern accessible telecommunication infrastructure. ICT accessibility is the foundation for building a digital economy. The author examines the features of a competitive digital economy (re-industrialization of the economy), as well as the requirements for it. A separate aspect is considered by the cognitive technologies of the innovative ecosystem, which are an integral part of a competitive digital economy.

description: Examples are presented of how the geometric notion of the mean curvature is used for general magnetic field configurations and magnetic surfaces. It is shown that the mean magnetic curvature is related to the variation of the absolute value of the magnetic field along its lines. Magnetic surfaces of constant mean curvature are optimum for plasma confinement in multimirror open confinement systems and rippled tori.

description: Nutrient scarcity is a frequent adverse condition that organisms face during their development. This condition may lead to long-lasting effects on the metabolism and behaviour of adults due to developmental epigenetic modifications. Here, we show that reducing nutrient availability during larval development affects adult spontaneous activity and sleep behaviour, together with changes in gene expression and epigenetic marks in the Mushroom bodies (MBs). We found that open chromatin regions map to 100 of 241 transcriptionally upregulated genes in the adult MBs, these new opening zones are preferentially located in regulatory zones such as promoter-TSS and introns. Importantly, opened chromatin at the Dopamine 1-like receptor 2 transcription start site correlates with increased expression. Thus, adult administration of a dopamine antagonist reverses increased spontaneous activity and diminished sleep time observed in response to early-life nutrient restriction. In comparison, reducing dop1R2 expression in MBs also ameliorates these effects, albeit to a lesser degree. These results lead to the conclusion that increased dopamine signalling in the MBs of flies reared in a poor nutritional environment underlies the behavioural changes observed due to this condition during development.

description: We present a simple derivation of an expression for the superfluid density $ n_s \propto 1/λ^2 $ in superconductors with the tight binding energy dispersion. The derived expression is discussed in detail because of its distinction from the known expressions for ordinary superconductors with parabolic energy dispersion. We apply this expression for the experimental data analysis of the isotope effect in London penetration depth parameter $ λ$ in the BiSrCuO and YBaCuO family compounds near optimal doping, taking into account the orthorhombic distortion of crystal structure, and estimate the isotopic change of hopping parameters from the experimental data. We point out that $1/λ^2$ temperature behaviour is very sensitive to the ratio $ 2Δ_m(T=0)/ k_B T_c $ and estimate this quantity for a number of compounds.

Consistency of Markov chain quasi-Monte Carlo on continuous state spaces

description: The random numbers driving Markov chain Monte Carlo (MCMC) simulation are usually modeled as independent U(0,1) random variables. Tribble [Markov chain Monte Carlo algorithms using completely uniformly distributed driving sequences (2007) Stanford Univ.] reports substantial improvements when those random numbers are replaced by carefully balanced inputs from completely uniformly distributed sequences. The previous theoretical justification for using anything other than i.i.d. U(0,1) points shows consistency for estimated means, but only applies for discrete stationary distributions. We extend those results to some MCMC algorithms for continuous stationary distributions. The main motivation is the search for quasi-Monte Carlo versions of MCMC. As a side benefit, the results also establish consistency for the usual method of using pseudo-random numbers in place of random ones.
