Equilibri intermittenti e stasi  nell'evoluzione  di una ricercatrice (precaria)
Creators: name: AMADORI, CHIARA
Publisher: name: Zenodo
Year: 2024

description: Secondo la teoria degli equilibri intermittenti l'evoluzione procede a scatti, con episodi improvvisi di speciazione alternati a lunghi periodi di equilibrio (Eldredge & Gould, 1972). Intermittenza evolutiva come quella che vivono anche le ricercatrici ei ricercatori, fatta di stasi (spesso lunghe) e salti improvvisi. Le carriere dei precari in Italia sono, infatti, tutto fuorché lineari, dove bivi e cambiamenti di rotta - talvolta radicali - sono obbligati. In natura, la pressione selettiva più grande dipende dall’ambiente esterno, così come i fattori politici ed economici della società influenzano il mondo accademico. I precari in Italia non sono una specie in via di estinzione ma (purtroppo) sempre in aumento, soprattutto dopo le recenti proposte del Governo; sono quindi obbligati a cambiare “linea evolutiva” pur di sopravvivere. I cambiamenti di carriera non sono mai facili e in Italia le skills acquisite nella ricerca non sono facilmente trasferibili in altri contesti, mentre in Europa (soprattutto del nord), e nei paesi anglofoni, la transizione è molto più fluida. In questo percorso ad ostacoli del pre-ruolo, le categorie più fragili - tra cui le donne - sono ovviamente le più colpite. Le folli pressioni alla pubblicazione e all’accantonamento di fondi esterni per compensare il sottofinanziamento ministeriale, non si conciliano con le necessità della realtà che viviamo. Per questo, lunghe – talvolta perenni – stasi colpiscono maggiormente le precarie, che non possono proseguire “linearmente” la carriera. Eppure, in questi contesti germogliano spontanee delle iniziative bottom-up a supporto di queste categorie fragili nelle STEM, ed un esempio premiale è quello della Società Geologica Italiana e la sua Divisione dedicata alle pari opportunità. La mia esperienza di ricercatrice precaria ricalca proprio il modello di evoluzione intermittente, con stasi e transizioni tra Italia e Inghilterra. Grazie ad essa, ho coltivato attività di mentoring “fai da te” verso student* e precar*, tentando di dimostrare che anche l’impegno autonomo e quotidiano puo’ bilanciare la totale assenza di supporto delle istituzioni e avere effetti positivi a lungo termine.

description: Abstract This article aims to build a theoretical structure for understanding the role of social media in fueling revolutions, social dissent, and disorder, considering three different disciplinary perspectives: Organizational Change, Conflict Resolution, and Digital Media Studies. More explicitly, it depends on studies of the 2011 and 2019 Arab Springs respectively, survey, telecommunications empirical data, and social media sites. It also refers to literature that examines the relationship between social media engagement and civic engagement. Building on this foundation, the article analyzes and attempts to evaluate the impact of real and fake social media postings by individuals, state, and non-state actors regarding the Arab Spring. The use of social media, which was originally considered to have a constructive influence on spreading democracy, has been significantly considered in recent years as a tool of behavior modification and a means for 4th generation warfare. It has also been perceived lately as a threat to democracy and as a recruitment tool for extremists and terrorists.

description: We present a procedure to generate bipartite grids for simply connected domains in 2-D and 3-D of prescribed size and controlled regularity elements. The mesh elements $K$ of the triangulation satisfy $ζ_{K} \leq C$ where $ζ_{K}$ is the regularity and $C$ is a constant depending on the shape parameters of the initial mesh. Bipartite grids permit a well-posed mixed-mixed variational formulation of problems such as the porous media flow equation and other linear physical phenomena as well as Galerkin-type discontinuous relaxations.

title: The judicial response to the New Deal: the United States Supreme Court and economic regulations 1934-1936
Creators: name: Maidment, Richard A.
Publisher: name: University of Kent
Year: 2023

description: The behaviouralist movement in political science has had a profound effect on the study of American judicial institutions. Particularly in the nineteen fifties and sixties political scientists of a behavioural persuasion have argued that the study of courts and judges should be made more rigorous and scientific. To fulfill this intention, political scientists have developed a wide array of different methodologies to examine various aspects of the judicial process. Most of these methodologies, however, share an underlying assumption that the explanation of judicial behaviour must be sought outside of the legal process in such factors as the judge's personal, social or political predilections or his socio-economic background. Most judicial behaviouralists have consequently de-emphasised the importance of legal factors and in particular have dismissed the role of legal rules in judicial decisionmaking. In this respect judicial behaviouralism is indebted to the work of the American legal realist movement who originally questioned the efficacy of rules in judicial decision-making. This dissertation examines a period of United States Supreme Court history when the Court was accused of being flagrantly political. The response of the Court to the New Deal's economic legislation has been portrayed as the judicial embodiment of the political conservation of the majority of the Court, which tends to support the dominant behaviouralist assumptions on judicial decision-making. This dissertation, however, suggests that the Supreme Court's response to the New Deal between 1934 and 1936 was not based on the political and social ideology of the majority. Instead, the dissertation argues the Court's decisions were guided by a sense of history and constitutional propriety but above all by legal rules. The dissertation concludes by suggesting that analysis of judicial decision-making offered by a number of judicial behaviouralists is misplaced as far as the United States Supreme Court's response to the New Deal between 1934 and 1936 is concerned.

description: Coupling regular topologies with optimized routing algorithms is key in pushing the performance of interconnection networks of HPC systems. In this paper we present Dmodc, a fast deterministic routing algorithm for Parallel Generalized Fat-Trees (PGFTs) which minimizes congestion risk even under massive topology degradation caused by equipment failure. It applies a modulo-based computation of forwarding tables among switches closer to the destination, using only knowledge of subtrees for pre-modulo division. Dmodc allows complete rerouting of topologies with tens of thousands of nodes in less than a second, which greatly helps centralized fabric management react to faults with high-quality routing tables and no impact to running applications in current and future very large-scale HPC clusters. We compare Dmodc against routing algorithms available in the InfiniBand control software (OpenSM) first for routing execution time to show feasibility at scale, and then for congestion risk under degradation to demonstrate robustness. The latter comparison is done using static analysis of routing tables under random permutation (RP), shift permutation (SP) and all-to-all (A2A) traffic patterns. Results for Dmodc show A2A and RP congestion risks similar under heavy degradation as the most stable algorithms compared, and near-optimal SP congestion risk up to 1% of random degradation.

description: Object recognition is still an impediment in the field of computer vision and multimedia retrieval.Defining an object model is a critical task. Shape information of an object play a critical role in the process of object recognition. Extraction of boundary information of an object from the multimedia data and classifying this information with associated objects is the primary step towards object recognition. Rasters play an important role while computing object boundary. The trade-off lies with the dimensionality of the object versus computational cost while achieving maximum efficiency. In this treatise an attempt is made to evaluate the performance of circular and spiral raster models in terms of average retrieval efficiency and computational cost.

Can Blockchain Be a Basis to Ensure Transparency in an Agricultural Supply Chain?

description: Many supply chains within developing countries lack transparency and are fraught with fraud, corruption, and a substantial number of intermediaries. For several decades, the cocoa sector has faced multiple social, economic, and environmental challenges, some of which include the issue of child labor and very low incomes for farmers, leading to poor living conditions. Blockchain technology has a high potential to reduce—or completely eradicate—some of these hurdles. In this article, we present a blockchain-based solution based on the open-source framework Hyperledger Fabric for the cocoa supply chain to promote transparency and reduce fraud. In doing so, we explicitly describe how farmers can be directly integrated into the whole blockchain solution considering the limited infrastructure, knowledge, and technologies available to them. Since about 70% of all cocoa worldwide is produced in West Africa, this case study uses the cocoa sector in Ghana as an example.

description: The determination of chemical compositions for materials plays a paramount role in materials design and discovery. Optimization of such compositions can be a very expensive trial-and-error task, specially when the desired properties are very sensitive to the composition variations. As the number of the elements and the variations of the possible composition values increase, the number of the possible candidate materials increases exponentially. In this work, we present an efficient machine-learning-assisted method to optimize the chemical compositions of materials for desired mechanical properties. The method utilizes a hybrid approach combining Monte Carlo tree search (MCTS) and an expansion policy neural network. The efficiency of this method was demonstrated by optimizing chemical compositions of a 7-element Ni-base superalloy ([Al, Co, Cr, Mo, Nb, Ti, Ni]) to avoid the precipitation of gamma-prime (γ’) phase during cooling in 3D additive manufacturing process. We were able to find Ni-base superalloys that could not be found by trial-and-error search or by using human experience.

description: High-Performance Computing (HPC) clusters are made up of a variety of node types (usually compute, I/O, service, and GPGPU nodes) and applications don't use nodes of a different type the same way. Resulting communication patterns reflect organization of groups of nodes, and current optimal routing algorithms for all-to-all patterns will not always maximize performance for group-specific communications. Since application communication patterns are rarely available beforehand, we choose to rely on node types as a good guess for node usage. We provide a description of node type heterogeneity and analyse performance degradation caused by unlucky repartition of nodes of the same type. We provide an extension to routing algorithms for Parallel Generalized Fat-Tree topologies (PGFTs) which balances load amongst groups of nodes of the same type. We show how it removes these performance issues by comparing results in a variety of situations against corresponding classical algorithms.
Scalar Tensor Teleparallel Dark Gravity via Noether Symmetry

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In this paper, in the framework of teleparallel gravity we consider scalar tensor theories of gravity in which scalar fields are nonminimal coupled to torsion scalar. Noether symmetry of the Lagrangian of such a theory for the Friedman-Robertson-Walker spacetime is used to determine the explicit forms for the coupling function and for the potential, and it is shown that both must be power-law forms as a functions of the scalar field. The solutions of the field equations for the considered models are presented by using the results obtained from the Noether symmetry. It is shown that the equation of state parameter in the present model can cross the phantom divide line for a special case with the coupling function $F(ϕ) = \frac{3}{16} ϕ^2$ and for the potential $V(ϕ) = λϕ^{2}$.

description: While entanglement and violation of Bell inequalities were initially thought to be equivalent quantum phenomena, we now have different examples of entangled states whose correlations can be described by local hidden--variable models and, therefore, do not violate any Bell inequality. We provide an up to date overview of the existing local hidden--variable models for entangled quantum states, both in the bipartite and multipartite case, and discuss some of the most relevant open questions in this context. Our review covers twenty five years of this line of research since the seminal work by Werner [R. F. Werner, Phys. Rev. A 40, 8 (1989)] providing the first example of an entangled state with a local model, which in turn appeared twenty five years after the seminal work by Bell [J. S. Bell, Physics 1, 195 (1964)], about the impossibility of recovering the predictions of quantum mechanics using a local hidden--variables theory.

description: We determine the metallicities for globular clusters (GCs) in the WLM and IKN dwarf galaxies, using VLT/UVES and Keck/ESI spectroscopy. For the WLM GC we also measure detailed abundance ratios for a number of light, alpha, Fe-peak and n-capture elements. We find low metallicities of [Fe/H]=-2.0 and -2.1 for the WLM GC and the GC IKN-5, respectively. We estimate that 17%-31% of the metal-poor stars in WLM belong to the GC, and IKN-5 may even contain a similar number of metal-poor stars as the whole of the IKN dwarf itself. These high ratios of metal-poor GCs to field stars are in tension with GC formation scenarios that require GCs to have lost a very large fraction of their initial mass. The GCs in the WLM and IKN dwarf galaxies resemble those in the Fornax dSph by being significantly more metal-poor than a typical halo GC in the Milky Way and other large galaxies. They are also substantially more metal-poor than the bulk of the field stars in their parent galaxies. The overall abundance patterns in the WLM GC are similar to those observed for GCs in the Fornax dSph: [Ca/Fe] and [Ti/Fe] are super-Solar at about +0.3 dex, while [Mg/Fe] is less elevated than [Ca/Fe] and [Ti/Fe]. The [Na/Fe] ratio is similar to the averaged [Na/Fe] ratios in Milky Way GCs, but higher than those of Milky Way halo stars. Fe-peak (Mn, Sc, Cr) and heavy elements (Ba, Y, La) generally follow the trends seen in the Milky Way halo. The relatively high Na abundance in the WLM GC suggests that the [Na/O] anti-correlation is present in this cluster.

description: The proposed research performs the capacity analysis of the wireless channel described by the fluctuating double-Rayleigh with the line-of-sight model. The closed-form analytical expressions for the conditional capacity (in the case of arbitrary noninteger fading parameter) and the ergodic capacity (in the case of the integer fading parameter) are derived in terms of the extended generalized bivariate Meijer G-function. The exact solutions are succeeded by the approximating expressions deduced for the cases of small and large ratios between the Rician K-factor and the fading parameter. The performed numeric simulation verifies the correctness of the derived results and analyzes the proposed capacity approximation quality performance.

description: Dynamic social opinion models have been widely studied on undirected networks, and most of them are based on spin interaction models that produce a consensus. In reality, however, many networks such as Twitter and the World Wide Web are directed and are composed of both unidirectional and bidirectional links. Moreover, from choosing a coffee brand to deciding who to vote for in an election, two or more competing opinions often coexist. In response to this ubiquity of directed networks and the coexistence of two or more opinions in decision-making situations, we study a non-consensus opinion model introduced by Shao et al. \cite{shao2009dynamic} on directed networks. We define directionality $ξ$ as the percentage of unidirectional links in a network, and we use the linear correlation coefficient $ρ$ between the indegree and outdegree of a node to quantify the relation between the indegree and outdegree. We introduce two degree-preserving rewiring approaches which allow us to construct directed networks that can have a broad range of possible combinations of directionality $ξ$ and linear correlation coefficient $ρ$ and to study how $ξ$ and $ρ$ impact opinion competitions. We find that, as the directionality $ξ$ or the indegree and outdegree correlation $ρ$ increases, the majority opinion becomes more dominant and the minority opinion's ability to survive is lowered.

The good is: we're starting to realise that a lot of the problem boils down to copyright issues. The emergence and normalisation of rights retention is undoubtedly healthy. The bad news is: there are significant problems in the way that money is being spent to enable open access e.g. "transformative agreements" (sic). Transformative for whom? The ugly: Journal Impact Factor™ is statistically illiterate, negotiable, and irreproducible, but some researchers are still making decisions using it. The real question now is not can we get universal open access to research, but how.

description: Since the discovery of Hawking radiation, its consistency with quantum theory has been widely questioned. In the widely described picture, irrespective of what initial state a black hole starts with before collapsing, it eventually evolves into a thermal state of Hawking radiations after the black hole is exhausted. This scenario violates the principle of unitarity as required for quantum mechanics and leads to the acclaimed "information loss paradox". This paradox has become an obstacle or a reversed touchstone for any possible theory to unify the gravity and quantum mechanics. Based on the results from Hawking radiation as tunneling, we recently show that Hawking radiations can carry off all information about the collapsed matter in a black hole. After discovering the existence of information-carrying correlation, we show in great detail that entropy is conserved for Hawking radiation based on standard probability theory and statistics. We claim that information previously considered lost remains hidden inside Hawking radiation. More specifically, it is encoded into correlations between Hawking radiations. Our study thus establishes harmony between Harking radiation and the unitarity of quantum mechanics, which establishes the basis for a significant milestone towards resolving the long-standing information loss paradox. The paper provides a brief review of the exciting development on Hawking raidation. In addition to summarize our own work on this subject, we compare and address other related studies.

description: Coherent tunneling by adiabatic passage (CTAP) is a well-established technique for robust spatial transport of quantum particles in linear chains. Here we introduce two exactly-solvable models where the CTAP protocol can be extended to two-dimensional lattice geometries. Such bi-dimensional lattice models are synthesized from time-dependent second-quantization Hamiltonians, in which the bosonic field operators evolve adiabatically like in an ordinary three-level CTAP scheme thus ensuring adiabatic passage in Fock space.

description: Due to the lack of training labels and the difficulty of annotating, dealing with adverse driving conditions such as nighttime has posed a huge challenge to the perception system of autonomous vehicles. Therefore, adapting knowledge from a labelled daytime domain to an unlabelled nighttime domain has been widely researched. In addition to labelled daytime datasets, existing nighttime datasets usually provide nighttime images with corresponding daytime reference images captured at nearby locations for reference. The key challenge is to minimize the performance gap between the two domains. In this paper, we propose LoopDA for domain adaptive nighttime semantic segmentation. It consists of self-loops that result in reconstructing the input data using predicted semantic maps, by rendering them into the encoded features. In a warm-up training stage, the self-loops comprise of an inner-loop and an outer-loop, which are responsible for intra-domain refinement and inter-domain alignment, respectively. To reduce the impact of day-night pose shifts, in the later self-training stage, we propose a co-teaching pipeline that involves an offline pseudo-supervision signal and an online reference-guided signal `DNA' (Day-Night Agreement), bringing substantial benefits to enhance nighttime segmentation. Our model outperforms prior methods on Dark Zurich and Nighttime Driving datasets for semantic segmentation. Code and pretrained models are available at https://github.com/fy-vision/LoopDA.

description: We study here the curious particle dynamics resulting from electro-osmotic flow around a microchannel junction corner whose dielectric walls are weakly polarizable. The hydrodynamic velocity field is obtained via superposition of a linear irrotational term associated with the equilibrium zeta potentials of both the microchannel and particle surfaces and the non-linear induced-charge electro-osmotic flow which originates from the interaction of the externally applied electric field on the charge cloud it induces at the solid-liquid interface. The particle dynamics are analyzed by considering dielectrophoretic forces via the addition of a mobility term to the flow field in the limit of Stokes drag law. The former, non-divergence free term is responsible for migration of particles towards the sharp microchannel junction corner, where they can potentially accumulate. Experimental observations of particle trapping for various applied electric fields and microparticle size are rationalized in terms of the growing relative importance of the dielectrophoretic force and induced-charge contributions to the global velocity field with increasing intensity of the externally applied electric field.

description: Lasers are becoming a more and more important tool in cutting and shaping materials. Improving precision and effectivity is an ongoing demand in science and industry. One possibility are double pulses. Here we study laser ablation of aluminum by the two-temperature model. There the laser is modeled as a source in a continuum heat conduction equation for the electrons, whose temperature then is transferred to a molecular dynamics particle model by an electron-phonon coupling term. The melting and ablation effectivity is investigated depending on the relative intensity and the time delay between two Gaussian shaped laser pulses. It turns out that at least for aluminum the optimal pulse shapes are standard Gaussian pulses. For double pulses with delay times up to 200 ps we find a behavior as observed in experiment: the ablation depth decreases beyond a delay of 10 ps even if one does not account for the weakening at the second pulse due to laser-plasma interaction.

description: CodEval is a code evaluation tool that integrates with the Canvas Learning Management System to automatically evaluates students' work within a few minutes of the submission. This early feedback allows students to catch and correct problems in their submissions before their submission is graded and gives them a clear idea of the quality of their submission. CodEval handles the tedious aspects of grading, such as compiling and running tests, leaving graders more time to spend on the qualitative aspect of grading. Before using CodEval, instructors would not have a clear view of the student's comprehension of the concept evaluated by the assignment until after the due date. CodeEval helps instructors identify and address the gaps in students' understanding and thus helps more students successfully complete the assignment. We implemented CodEval using Python using the public Canvas API. Any instructor or grader for a Canvas course can use CodEval to automatically evaluate submissions for programming assignments. We developed a syntax to express requirements of submissions such as compilation parameters, inputs, outputs, command-line arguments, timeouts, exit codes, functions used, files generated, output validators, and more. We have made CodEval open source. CodEval is an easy tool for students, graders, and instructors and seamlessly integrates with Canvas. We share our experience with using CodEval in two classes with a total of 90 students and multiple coding assignments.

description: Si la recherche en sciences sociales sur le rôle des cabinets de conseil privés dans l’action publique est foisonnante, leur intervention dans la gestion publique de crises sanitaires ou d’épidémies est peu étudiée. La pandémie de COVID-19 a pourtant révélé un recours important à ces firmes de la part d’administrations publiques de nombreux pays. Cette revue exploratoire des écrits scientifiques a pour objectif d’identifier les recherches qui portent sur la participation de ces cabinets au gouvernement d’épidémies et de crises sanitaires survenues depuis 2000 : que disent-elles du rôle de ces cabinets et quelles méthodes sont mobilisées ? Les étapes du modèle PRISMA-ScR ont permis d’identifier seulement 24 références depuis 2000. Trois approches sont mobilisées par les auteur·e·s qui déterminent leur analyses sur le rôle des cabinets : l’approche gestionnaire, la consultocratie et l’hybridation des élites. Cette revue permet de rendre compte d’un point aveugle des écrits scientifiques et appelle à la réalisation de recherches empiriques sur le sujet.
description: While there is ample research in the social sciences on the role of private consulting firms in public action, their intervention in public management of health crises or epidemics is poorly studied. However, the COVID-19 pandemic has revealed a significant recourse to these firms by public administrations in many countries. The purpose of this exploratory review of scientific literature is to identify research on the involvement of these firms in the government of epidemics and health crises that have occurred since 2000. What do they say about the role of these firms, and what methods are used? The steps of the PRISMA-SCR model have identified only 24 references since 2000. The authors use three approaches to analyze the role of the firms: the managerial approach, consultocracy and the hybridization of the elites. This review reports on a blind point of scientific writing and calls for the conduct of empirical research on the subject.

description: The Verwey transition in magnetite (Fe3O4 ) is the prototypical metal-insulator transition and has eluded a comprehensive explanation for decades. A major element of the challenge is the complex interplay between charge order and lattice distortions. Here we use ultrafast electron diffraction (UED) to disentangle the roles of charge order and lattice distortions by tracking the transient structural evolution after charge order is melted via ultrafast photoexcitation. A dual stage response is observed in which X3, X1, and Delta5 type structural distortions occur on markedly different timescales of 0.7 to 3.2 ps and longer than 3.2 ps. We propose that these distinct timescales arise because X3 type distortions strongly couple to the trimeron charge order, whereas the Delta5-distortions are more strongly associated with monoclinic to cubic distortions of the overall lattice. Our work aids in clarifying the charge lattice interplay using UED method and illustrates the disentanglement of the complex phases in magnetite.

Starbursts triggered by inter-galactic tides and interstellar compressive turbulence

description: Using parsec-resolution simulations of a typical galaxy merger, we study the triggering of starbursts by connecting the (inter-)galactic dynamics to the structure of the interstellar medium. The gravitational encounter between two galaxies enhances tidal compression over large volumes, which increases and modifies the turbulence, in particular its compressive mode with respect to the solenoidal one. This generates an excess of dense gas leading to intense star formation activity. Along the interaction, the compressive turbulence modifies the efficiency of gas-to-star conversion which, in the Schmidt-Kennicutt diagram, drives the galaxies from the sequence of discs to that of starbursts.
