The role of companion animals in human well-being: A mixed methods approach with a focus on ornamental fishes
Creators: name: Clements, Heather
Publisher: name: Zenodo
Year: 2024

description: Human-animal interaction has been linked to better well-being in various populations and settings, but most research has involved animals which interact with humans through physical touch, such as dogs. Less is known about the effects of engaging with animals such as ornamental fishes where the interaction is based primarily on visual exposure. The primary aim of this thesis was to improve understanding of whether and how engagement with ornamental fishes influences human well-being. A systematic review was conducted to identify the psychological and physiological effects of interacting with fishes in aquaria, and two studies (one mixed methods, one qualitative) were conducted to understand the effects of engagement with fishes in the workplace. Studies planned in nurseries and care homes could not proceed due to the COVID-19 pandemic; instead a secondary aim of the thesis became to understand the impact that companion animals, and in particular ornamental fishes, had upon human well-being during the pandemic and ongoing restrictions. A mixed methods study examined the relationships between companion animal guardianship, loneliness and mental well-being during the pandemic, and a quasi-experimental study assessed the effects of companion animal guardianship on the well-being and productivity of people working from home. Across all studies there was no quantitative evidence that engagement with ornamental fishes influences human well-being. Qualitative evidence suggested that human-fish interaction may have an emotional element, and so goes beyond the visual dimension; further research is needed to fully understand human-fish relationships. A tone of dismissiveness towards fishes was also identified, and suggested that fishes may be viewed with a lesser regard than other companion animals; this may have implications for fish welfare and warrants further consideration. With regards to companion animal guardianship more broadly, qualitative evidence suggested that guardians felt their companion animals were a positive influence during the pandemic, but there was no quantitative evidence to support this. There was also no evidence that companion animal guardianship was associated with well-being or productivity for people working from home. Level of engagement was associated with well-being outcomes for dog guardians, and to alesser extent cat guardians, and should be taken into consideration in future studies. Finally, there was qualitative evidence that some guardians found companion animals to be a source of stress; this may explain conflicting evidence regarding the benefits of companion animal guardianship as these additional stresses may counteract any benefits associated with human-animal interaction.

Geografie del sacro e salvaguardia ambientale. Un’applicazione dell’ecologia di genere alle comunità etniche della frontiera Sino-Tibetana
Creators: name: Previato, Tommaso
Publisher: name: Storia delle Donne
Year: 2019

description: Prendendo come caso di studio le società tibetana e mosuo dello Yunnan nord-occidentale, il saggio esamina le ricadute che integrazione economica e politiche territoriali possono avere sui delicati equilibri ecologici e le strategie di sussistenza di piccole comunità etniche sulle pendici dell’altopiano himalayano. Attenzione particolare è rivolta a quell’insieme di credenze, pratiche cultuali e rituali che scandiscono percezione, comprensione e modalità di rappresentazione dell’ambiente naturale, nonché al ruolo svolto da donne indigene nella conservazione della biodiversità. Il saggio contribuisce così a gettare luce sulle differenze di genere nell’accesso, la gestione e l’utilizzo delle risorse di ecosistemi alpini laddove le interazioni uomo-ambiente sono regolate da una combinazione di tabù a sfondo religioso, meccanismi di coordinamento di tipo orizzontale, soluzioni eco-sostenibili e relazioni più paritarie fra i sessi.

description: A prototypical graph problem is centered around a graph-theoretic property for a set of vertices and a solution to it is a set of vertices for which the desired property holds. The task is to decide whether, in the given graph, there exists a solution of a certain quality, where we use size as a quality measure. In this work, we are changing the measure to the fair measure [Lin&Sahni: Fair edge deletion problems. IEEE Trans. Comput. 89]. The measure is k if the number of solution neighbors does not exceed k for any vertex in the graph. One possible way to study graph problems is by defining the property in a certain logic. For a given objective an evaluation problem is to find a set (of vertices) that simultaneously minimizes the assumed measure and satisfies an appropriate formula. In the presented paper we show that there is an FPT algorithm for the MSO Fair Vertex Evaluation problem for formulas with one free variable parameterized by the twin cover number of the input graph. Here, the free variable corresponds to the solution sought. One may define an extended variant of MSO Fair Vertex Evaluation for formulas with l free variables; here we measure a maximum number of neighbors in each of the l sets. However, such variant is W[1]-hard for parameter l even on graphs with twin cover one. Furthermore, we study the Fair Vertex Cover (Fair VC) problem. Fair VC is among the simplest problems with respect to the demanded property (i.e., the rest forms an edgeless graph). On the negative side, Fair VC is W[1]-hard when parameterized by both treedepth and feedback vertex set of the input graph. On the positive side, we provide an FPT algorithm for the parameter modular width.

description: Phosphate (Pi) transporters in plants mediate phosphorus (P) acquisition, translocation and recycling. In this study, a putative high-affinity Pi transporter gene (CoPht1;3, GenBank KF989483.1) was isolated and characterised from oil-tea tree (Camellia oleifera Abel.). The CoPht1;3 contained a 1575-bp open reading frame encoding 525 amino acid residues. It shared 98.67%, 88.50%, 86.50%, and 85.60% amino acid identities with the Pht1s of Camellia sinensis, Camelina sativa, Arabidopsis thaliana and Hevea brasiliensis, respectively. The CoPht1;3 exhibited all essential motifs and 12 transmembrane helix common to the Pht1 family of Pi transporters, in which α-helical structure accounted for 48.66% in protein. The CoPht1;3 was localised in tonoplast detected by transient expression of CoPht1;3:eGFP in tobacco epidermal cells. Quantitative real-time PCR showed that CoPht1;3 mRNA was detected in root, leaf and stem, but its transcript was most abundant in young leaves under low P supply. The results suggested that CoPht1;3 might be a high P affinity transporter. CoPht1;3 overexpression enhanced absorption of P and increased biomass of the transgenics. CoPht1;3 may play a key role in the transportation process of P in oil-tea tree leaves and could be targeted as a candidate gene to improve oil-tea tree P efficiency.

description: Let p be a prime, K a field of characteristic p, G a locally finite p-group, KG the group algebra, and V the group of the units of KG with augmentation 1. The anti-automorphism g\mapsto g^{-1} of G extends linearly to KG; this extension leaves V setwise invariant, and its restriction to V followed by v\mapsto v^{-1} lives an automorphism of V. The elements of V fixed by this automorphism are called unitary; they form a subgroup. Our first theorem describes the K and G for which this subgroup is normal in V. For each element g in G, let \bar{g} denote the sum (in KG) of the distinct powers of g. The elements 1+(g-1)h\bar{g} with g,h\in G are the bicyclic units of KG. Our second theorem describes the K and G for which all bicyclic units are unitary.

description: While investigating odd-cycle free hypergraphs, Győri and Lemons introduced a colored version of the classical theorem of Erdős and Gallai on $P_k$-free graphs. They proved that any graph $G$ with a proper vertex coloring and no path of length $2k+1$ with endpoints of different colors has at most $2kn$ edges. We show that Erdős and Gallai's original sharp upper bound of $kn$ holds for their problem as well. We also introduce a version of this problem for trees and present a generalization of the Erdős-Sós conjecture.

description: We present diffusion Monte Carlo (DMC) results on a new metastable, superfluid phase above the crystal ground state in two-dimensional 4He at densities > 0.065 1/A^2. The state is anisotropic with hexatic orbital order. This implies that the liquid--solid phase transition has two stages: A second order phase transition from the isotropic superfluid to the hexatic superfluid, followed by a first order transition that localizes atoms into the triangular crystal order. This metastable hexatic phase has finite condensate fraction and it provides a natural explanation for the superflow in the supersolid grain boundaries.

description: We present a quantum algorithm for simulating the dynamics of Hamiltonians that are not necessarily sparse. Our algorithm is based on the input model where the entries of the Hamiltonian are stored in a data structure in a quantum random access memory (qRAM) which allows for the efficient preparation of states that encode the rows of the Hamiltonian. We use a linear combination of quantum walks to achieve poly-logarithmic dependence on precision. The time complexity of our algorithm, measured in terms of the circuit depth, is $O(t\sqrt{N}\|H\|\,\mathrm{polylog}(N, t\|H\|, 1/ε))$, where $t$ is the evolution time, $N$ is the dimension of the system, and $ε$ is the error in the final state, which we call precision. Our algorithm can be directly applied as a subroutine for unitary implementation and quantum linear systems solvers, achieving $\widetilde{O}(\sqrt{N})$ dependence for both applications.

description: Come possono le educatrici femministe adulte usare le gallerie d'arte e i musei per promuovere la consapevolezza di genere e il cambiamento? La nostra risposta è stata la Feminist Museum Hack, una pratica pedagogica, metodologica, analitica e interventista adattabile che usiamo nell'insegnamento in classe, nella facilitazione dei laboratori comunitari, nelle ricerche e in una varietà di musei e gallerie in Canada e in Europa. In questo articolo, discutiamo di come l'hack si basa sulle teorie della rappresentazione e sulle metodologie visuali e discorsive femministe per smascherare, interrogare e decostruire l'epistemologia patriarcale della maestria che si nasconde nelle immagini e nelle narrazioni delle mostre per produrre, plasmare e mobilitare una comprensione problematica di maschile, femminile e "l'altro". Come pedagogia della possibilità, l'Hack stimola il potere della visualità sotto forma di uno sguardo oppositivo femminista in grado di vedere, leggere e immaginare il mondo come se potesse essere altrimenti.

Anche l’etnografia ha dato spazio ai costumi valdesi, ai luoghi, alle abitudini montanare e alle virtù di questo popolo-chiesa. Qui in questo piccolo spazio, luogo simbolico più che museo, troviamo invece non tanto “un’altra storia”, ma alcune storie di donne valdesi. Il Medioevo valdese, la Riforma in Germania e in Svizzera, il Puritanesimo inglese, la resistenza ugonotta in Francia, il Movimento suffragista americano ci sono apparsi più accessibili raccontati attraverso vite di donne che hanno pensato, scritto e agito anche se la Storia sembra averle dimenticate.

description: We consider the localization problem of multiple wideband sources in a multi-path environment by coherently taking into account the attenuation characteristics and the time delays in the reception of the signal. Our proposed method leaves the space for unavailability of an accurate signal attenuation model in the environment by considering the model as an unknown function with reasonable prior assumptions about its functional space. Such approach is capable of enhancing the localization performance compared to only utilizing the signal attenuation information or the time delays. In this paper, the localization problem is modeled as a cost function in terms of the source locations, attenuation model parameters and the multi-path parameters. To globally perform the minimization, we propose a hybrid algorithm combining the differential evolution algorithm with the Levenberg-Marquardt algorithm. Besides the proposed combination of optimization schemes, supporting the technical details such as closed forms of cost function sensitivity matrices are provided. Finally, the validity of the proposed method is examined in several localization scenarios, taking into account the noise in the environment, the multi-path phenomenon and considering the sensors not being synchronized.

description: In the last decade, the development of Ultrafast Electron Diffraction (UED) and Microscopy (UEM) has enabled the imaging of atomic motion in real time and space. These pivotal table-top tools opened the door for a vast range of applications in different areas of science spanning chemistry, physics, materials science, and biology. We first discuss the basic principles and recent advancements, including some of the important applications, of both UED and UEM. Then, we discuss the recent advances in the field that have enhanced the spatial and temporal resolutions, where the latter, however, is still limited to a few hundreds of femtoseconds, preventing the imaging of ultrafast dynamics of matter on the scale of several tens of femtoseconds. Then, we present our new optical gating approach for generating an isolated 30 fs electron pulse with sufficient intensity to attain a temporal resolution on the same time scale. This achievement allows, for the first time, imaging the electron dynamics of matter. Finally, we demonstrate the feasibility of the optical gating approach to generate an isolated attosecond electron pulse, utilizing our recently demonstrated optical attosecond laser pulse, which paves the way for establishing the field of Attomicroscopy, ultimately enabling us to image the electron motion in action.

description: Low Energy Electron Microscopy (LEEM) is a specialized surface-sensitive microscopy technique utilizing electron with energies more than 1000 times lower than regular EM. This provides unique measurement opportunities, but also challenges in the analysis of the data. Here, we showcase how we utilize Numpy, Scipy, Dask and Scikit Learn and other parts of the scientific python stack to implement image analysis techniques, previously described for other microscopy techniques, but adapted to the specific challenges of LEEM [1,2]. Amongst others, we implement fast, parallelized, image (stack) registration and image stitching using Dask. We show that the image registration algorithm is, in the best-case, accurate to the sub-pixel level results and fast enough to enable registration of 500 images within 7 minutes on a regular desktop CPU, enabling per-pixel analysis of spectroscopic datasets, where energy is added to the images as a third dimension. Similarly, the stitching algorithm allows for the creation of 100Mpixel+ overview images from tiles with estimated positions. In summary, we show that the use of the scientific python stack allows for easy adoption to specific peculiarities of different imaging techniques and even individual datasets. We anticipate the code from this work can be adapted to be applied to other forms of electron microscopy such as PEEM, scanning tunneling microscopy, and others, providing a open source, Python alternative to existing closed source / undisclosed implementations in often proprietary languages.

Detection of faint companions through stochastic speckle discrimination

Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: We propose a new post-processing technique for the detection of faint companions from a sequence of adaptive optics corrected short exposures. The algorithm exploits the difference in shape between the on-axis and off-axis irradiance distributions and it does not require the signal to be above the noise level. We show that the method is particularly useful in dealing with static speckles. Its application to real and simulated data gives excellent results in the low-signal regime where it outperforms the standard approach of computing signal-to-noise ratio on one long exposure. We also show that accurate noise estimation in adaptive optics images of close companions is rendered impossible due to the presence of static speckles. This new method provides means of reliable estimation of the confidence intervals for the detection hypothesis.

description: We present an underground cosmic ray muon tomographic experiment imaging 3D density of overburden, part of a joint study with differential gravity. Muon data were acquired at four locations within a tunnel beneath Los Alamos, New Mexico, and used in a 3D tomographic inversion to recover the spatial variation in the overlying rock-air interface, and compared with a priori knowledge of the topography. Densities obtained exhibit good agreement with preliminary results of the gravity modeling, which will be presented elsewhere, and are compatible with values reported in the literature. The modeled rock-air interface matches that obtained from LIDAR within 4 m, our resolution, over much of the model volume. This experiment demonstrates the power of cosmic ray muons to image shallow geological targets using underground detectors, whose development as borehole devices will be an important new direction of passive geophysical imaging.

Roman Women and Public History: la creatività del Web

description: Partendo dal dibattito sviluppatosi negli USA alla metà degli Anni Settanta sulla condizione femminile nel mondo antico, l’articolo sottolinea che ha contribuito a dare una lettura articolata dell’immagine delle donne romane. Ciò ha inciso non solo sulla storiografia posteriore, bensì oltre, come si ricava da alcuni recenti video YouTube sulle Roman Women, rinvenibili in rete. Essi mostrano la creatività dei loro autori, i loro diversi livelli di conoscenza e capacità tecniche. D’altro lato, proiettano lo spettatore nella vita quotidiana delle donne dell’antica Roma. In tal senso, questo genere di produzione può essere considerato un ottimo esempio di Public History applicata e risultare efficace a promuovere studi di gender in relazione alla storia romana.

title: Hidden Injuries Beyond the Bars: A Critical Analysis of Re-Entry Experiences of Older, Once Convicted Men
Creators: name: Rogers, S
Publisher: name: Liverpool John Moores University
Year: 2024

description: The life experiences of older people are becoming an ever-increasing topic of research due to the unprecedented numbers of those living longer. The increase in the number of older men in society has been mirrored by the unprecedented number of older men in prison, which has resulted in greater numbers of these men undergoing the community re-entry process. Despite the rapidly increasing numbers there is an absence of literature from England and Wales which has focused on older, once convicted men’s experiences of re-entry through gaining their individual accounts. This thesis critically analyses the pains of post imprisonment for once convicted men aged 50 and over, in the North-West of England. Dominant perceptions surrounding older, once convicted men are challenged by situating their re-entry experiences through a lens of socially constructed stigma, pain, and social death. The findings have shown that older, once convicted men endured the pains of re-entry in four primary areas, the experiences of imprisonment, the structural barriers to re-entry, supervision following incarceration and the impacts of a stigmatized identity. The findings have brought to light the painful, once hidden, relationship between older men and re-entry and have revealed how their lived realities, moulded by imprisonment and supervision in the community, and socially constructed by society, have led to living freedom in a state of social death.
Relationship between ferroelectricity and Dzyaloshinskii-Moriya interaction in multiferroics and the effect of bond-bending

description: We studied the microscopic mechanism of multiferroics, in particular with the "spin current" model (Hosho Katsura, Naoto Nagaosa and Aleander V. Balatsky, Phys. Rev. Lett. 95, 057205 (2005)). Starting from a system with helical spin configuration, we solved for the forms of the electron wave functions and analyzed their characteristics. The relation between ferroelectricity and Dzyaloshinskii-Moriya interaction (I. Dzyaloshinskii, J. Phys. Chem. Solids 4, 241 (1958) and T. Moriya, Phys. Rev. 120, 91 (1960)) is clearly established. There is also a simple relation between the electric polarization and the wave vector of magnetic orders. Finally, we show that the bond-bending exists in transition metal oxides can enhance ferroelectricity.

On the Kolmogorov-Sinai entropy of many-body Hamiltonian systems

description: The Kolmogorov-Sinai (K-S) entropy is a central measure of complexity and chaos. Its calculation for many-body systems is an interesting and important challenge. In this paper, the evaluation is formulated by considering $N$-dimensional symplectic maps and deriving a transfer matrix formalism for the stability problem. This approach makes explicit a duality relation that is exactly analogous to one found in a generalized Anderson tight-binding model, and leads to a formally exact expression for the finite-time K-S entropy. Within this formalism there is a hierarchy of approximations, the final one being a diagonal approximation that only makes use of instantaneous Hessians of the potential to find the K-S entropy. By way of a non-trivial illustration, the K-S entropy of $N$ identically coupled kicked rotors (standard maps) is investigated. The validity of the various approximations with kicking strength, particle number, and time are elucidated. An analytic formula for the K-S entropy within the diagonal approximation is derived and its range of validity is also explored.

Donne del Risorgimento e Public History nel 150° dell’Unità nazionale: appunti su un’inclusione irrisolta

description: La storia delle donne si sta gradualmente integrando alle narrazioni pubbliche della storia italiana, politica e sociale, nazionale e locale. I prodotti di Public History apparsi durante le celebrazioni del 150° dell’Unità o da esso sollecitati forniscono un buon banco di prova. Per quanto la ricchezza di riferimenti o la proposta di interi prodotti dedicati alle donne appaiano crescenti e qualitativamente in evoluzione, restano solidi e seri problemi inerenti non tanto allo specifico della Woman’s History, quanto piuttosto alla fruibilità del Risorgimento italiano al di fuori delle cerchie accademiche. In definitiva, il dialogo tra Public History e ricerca accademica di Storia delle donne si rivela avviato, talora già fecondo, ma ancor spesso trascurato o superficiale.

description: We propose a method for the determination of the interaction potential of Rydberg atoms. Specifically, we consider a laser-driven Rydberg gas confined in a one-dimensional lattice and demonstrate that the Rydberg atom number after a laser excitation cycle as a function of the laser detuning provides a measure for the Rydberg interaction coefficient. With the lattice spacing precisely known, the proposed scheme only relies on the measurement of the number of Rydberg atoms and thus circumvents the necessity to map the interaction potential by varying the interparticle separation.

subject: FOS: Physical sciences

description: Defect lines in conformal field theory can be perturbed by chiral defect fields. If the unperturbed defects satisfy su(2)-type fusion rules, the operators associated to the perturbed defects are shown to obey functional relations known from the study of integrable models as T-systems. The procedure is illustrated for Virasoro minimal models and for Liouville theory.

description: We have used pulsed magnetic fields up to 60Tesla to suppress the contribution of superconducting fluctuations(SCF)to the conductivity above Tc in a series of YBa2Cu3O6+x from the deep pseudogapped state to slight overdoping. Accurate determinations of the SCF conductivity versus temperature and magnetic field have been achieved. Their joint quantitative analyses with respect to Nernst data allow us to establish that thermal fluctuations following the Ginzburg-Landau(GL) scheme are dominant for nearly optimally doped samples. The deduced coherence length xi(T) is in perfect agreement with a gaussian (Aslamazov-Larkin) contribution for 1.01Tc

I musei delle donne nelle politiche europee. Dalle politiche sociali a quelle culturali
Creators: name: Da Milano, Cristina
Publisher: name: Storia delle Donne
Year: 2019

description: La storia delle donne e la loro rappresentazione nei musei è stata finora tenuta ai margini della discussione. Anche all'interno dell'Unione Europea la questione viene affrontata soprattutto in termini di parità di diritti, ma il ruolo delle donne nel settore culturale, lo sguardo femminile nella rilettura della storia, dell'antropologia e della scienza attraverso le mostre museali rimane ancora sullo sfondo. Se, da un lato, il progetto "She-Culture" - dedicato ai musei delle donne e finanziato dal programma Cultura 2007-2013 nell'ambito delle politiche culturali - sembrava un'apertura in questo senso, il mancato proseguimento dell'impegno a sostegno di iniziative analoghe porta alla conclusione che i musei delle donne non sono percepiti come strettamente appartenenti al settore culturale, ma piuttosto a quello sociale.

description: Persistent homology and persistent entropy have recently become useful tools for patter recognition. In this paper, we find requirements under which persistent entropy is stable to small perturbations in the input data and scale invariant. In addition, we describe two new stable summary functions combining persistent entropy and the Betti curve. Finally, we use the previously defined summary functions in a material classification task to show their usefulness in machine learning and pattern recognition.
