description: Approximately 60 percent of all rural homeowners had a mortgage on their home in 1979. About 80 percent of these were financed by conventional lenders; the remaining 20 percent were financed with some kind of Federal assistance. Most mortgaged rural homes were single-family detached units purchased by white males in their mid- to late thirties. The average home had three bedrooms and at least one full bathroom. Approximately 10 percent of rural homeowners reported their unit had some kind of defect. Most rural homeowners spent 20 percent of their income for housing related expenses such as mortgage payments, real estate taxes, property insurance, utilities, and trash collection. Median incomes and property values varied widely by mortgage type. Respondents were generally satisfied with their housing, neighborhood, and . community services.

description: Inquisitive modal logic, InqML, in its epistemic incarnation, extends standard epistemic logic to capture not just the information that agents have, but also the questions that they are interested in. We use the natural notion of bisimulation equivalence in the setting of InqML, as introduced in [Ciardelli/Otto: JSL 2021], to characterise the expressiveness of InqML as the bisimulation invariant fragment of first-order logic over natural classes of two-sorted first-order structures that arise as relational encodings of inquisitive epistemic (S5-like) models. The non-elementary nature of these classes crucially requires non-classical model-theoretic methods for the analysis of first-order expressiveness, irrespective of whether we aim for characterisations in the sense of classical or of finite model theory.

description: We work out some properties of a recently proposed globally N = 1 supersymmetric extension of relativistic fluid mechanics in four-dimensional Minkowski space. We construct the lagrangean, discuss its symmetries and the corresponding conserved Noether charges. We reformulate the theory in hamiltonian formulation, and rederive the (supersymmetry and internal) transformations generated by these charges. Super-Poincare algebra is also realized in this formulation.

description: [PT] O presente artigo tem por base uma investigação em curso sobre as transformações no mundo do trabalho em tempos de precariedade e mercantilização do trabalho, analisando diferentes formas de organização coletiva emergentes neste contexto. Neste artigo, debruçamo-nos, em particular, sobre o caso do setor das artes performativas, caracterizado por uma grande multiplicidade de atividades e situações laborais (artistas, produtores, mediadores, técnicos), mas onde o trabalho por projeto é preponderante, relacionando-se com uma hiper-flexibilidade, mas também intermitência e falta de proteção no emprego, formando o que alguns autores designaram de "precariado artístico" (Gill e Pratt 2008). Tendo por base a realidade portuguese, analisam-se diferentes formas de solidariedade entre os trabalhadores do setor (coletivos, cooperativas para partilha de recursos, associações, sistemas de apoio mútuo, colaboração inter-organizacional, ação coletiva). Esta análise evidencia também a forma como estes coletivos de trabalho são eles próprios permeados pela precariedade, chamando a atenção para o facto de que as respostas da sociedade civil não devem demitir o Estado da sua obrigação de garantir proteção social adequada a todos os trabalhadores e trabalhadoras. [EN] Modes of collective organizing in Portuguese performing arts This paper draws on ongoing research on the transformations in the world of work at times of precarity and work commodification, analyzing the different forms of collective organization that have emerged in this context. The paper focuses, in particular, on the case of the performing arts sector, characterized by a wide range of activities and work situations (artists, producers, mediators, technicians), but where project work is preponderant and relates to hyper-flexibility, but also intermittency and lack of protection in employment, forming what some authors have called an “artistic precariat” (Gill and Pratt 2008). Based on the Portuguese reality, different forms of workers’ solidarity are analyzed (collectives, shared resources cooperatives, associations, mutual support systems, inter-organizational collaboration, collective action). The analysis also shows how work collectives are themselves pervaded by precarity, calling attention to the fact that civil society responses should not dismiss the State from its obligation of guaranteeing access to adequate social protection to all workers.

description: Real milk prices 15-20 percent lower than in 1983 would approximately balance production and consumption under conditions projected for the dairy industry during the remainder of the eighties. Government purchase, storage, and disposal could effectively stabilize prices near this level, but these are wasteful means of raising prices and, thereby, enhancing producers' incomes. Other programs such as direct payments, supply control, and price discrimination can transfer income to farmers at less cost to society in the short run, but can lead to serious inefficiencies over time. Changes in the marketing order program to bring prices charged to processors and paid to producers more in line with the value of the services associated with the milk would contribute to the efficiency of the industry.

description: The hadronic reaction pp --> Sigma+ K0 p was measured exclusively at a beam momentum of 2.95 GeV/c using the TOF detector at the COSY storage ring. A narrow peak was observed in the invariant mass spectrum of the K0 p subsystem at 1530 +- 5 MeV/c2 with a significance of 4 - 6 standard deviations, depending on background assumptions. The upper limit of 18 +- 4 MeV/c2 (FWHM) for its width is given by the experimental resolution. The corresponding total cross section is estimated to be about 0.4 +- 0.1(stat) +- 0.1(syst) microbarn. Since a resonance in this subsystem must have strangeness S = + 1 we claim it to be the Theta+ state for which very recently evidence was found in various experiments.

Chlamydera maculata macdonaldi [sic] Mathews, 1913b: 78 (McDonald Ranges, Central Australia).
Now Chlamydera guttata guttata Gould, 1862. See Mathews, 1926: 332; Hartert, 1929a: 57; Mayr and Jennings, 1952: 8–10; Mayr, 1962c: 180; Gilliard, 1969: 361–363; Schodde and Mason, 1999: 632–633; and Frith and Frith, 2004: 417– 418; 2009a: 403.
HOLOTYPE: AMNH 679148, unsexed, collected in the Macdonnell Ranges (spelled McDonald Ranges on the original label), 23.45S, 133.20E (USBGN, 1957), Northern Territory, Australia, undated, from the Edwin Ashby Collection (no. 280). From the Mathews Collection (no. 3657) via the Rothschild Collection.
COMMENTS: Mathews apparently had the single specimen; it bears Ashby’s label, a Mathews Collection label marked ‘‘Type’’ with his catalog number 3657 (which was not otherwise mentioned), and a Rothschild type label. Mathews noted in the description that it was darker and had a much smaller bill than subguttata; Hartert (1929a: 57) dismissed it as ‘‘Bad specimen, bill half decayed, therefore appearing small.’’
A female obtained by S.A. White at Jay Water Hole in the Macdonnell Ranges on 3 September 1913 was not received by Mathews prior to his description of macdonaldi. It is now AMNH 679149 and bears a Mathews ‘‘Figured’’ label. It is the second female described by Mathews (1926: pl. 585, top fig., opp. p. 324; text p. 324) and the ‘‘Figured’’ label is so annotated by Hartert. It has no nomenclatural standing.

description: More frequent and longer drought periods are predicted threatening agricultural yield. The capacity of soils to hold water is a highly important factor controlling drought stress intensity for plants. Biogenic amorphous silica (bASi) pools in soils are in the range of 0–6% and are suggested to help plants to resist drought. In agricultural soils, bASi pools declined to values of ~1% or lower) due to yearly crop harvest, decreasing water holding capacity of the soils. Here, we assessed the contribution of bASi to water holding capacity (WHC) of soil. Consequently, ASi was mixed at different rates (0, 1, 5 or 15%) with different soils. Afterwards, the retention curve of the soils was determined via Hyprop method. Here we show that bASi increases the soil water holding capacity substantially, by forming silica gels with a water content at saturation higher than 700%. An increase of bASi by 1% or 5% (weight) increased the water content at any water potential and plant available water increased by up to > 40% or > 60%, respectively. Our results suggest that soil management should be modified to increase bASi content, enhancing available water in soils and potentially decreasing drought stress for plants in terrestrial ecosystems.

description: The body plan of the fruit fly is determined by the expression of just a handful of genes. We show that the spatial patterns of expression for several of these genes scale precisely with the size of the embryo. Concretely, discrete positional markers such as the peaks in striped patterns have absolute positions along the anterior-posterior axis that are proportional to embryo length, with better than 1% accuracy. Further, the information (in bits) that graded patterns of expression provide about position can be decomposed into information about fractional or scaled position and information about absolute position or embryo length; all of the available information is about scaled position, again with ~1% accuracy. These observations suggest that the underlying genetic network exhibits scale invariance in a deeper mathematical sense. Taking this mathematical statement seriously requires that the network dynamics have a zero mode, which connects to many other observations on this system.

description: Three food demand estimation procedures were compared to find which best measures the structure of food demand. These procedures were Seemingly Unrelated Regression, Block Additive, and Ordinary Least Squares. The focus was on food commodity substitution. The comparison of results was made on the basis of commodity demand and net change in calories consumed as estimated by each procedure. Each procedure projects a similar pattern of commodity demand and net caloric intake change. Overall, the Seemingly Unrelated RegressIcn procedure provides the most reasonable and consistent results.

description: The correlation between static magnetoelectric coupling and magnetic structure was investigated in $TbMn_{0.98}Fe_{0.02}O_{3}$ with magnetic field up to 8 T and down to 2 K. Single-crystal neutron diffraction experiments reveal a substantial increase in the temperature dependence of the incommensurate modulation wave vector of the antiferromagnetic phase as the magnetic field strength increases. Magnetic field-dependent pyroelectric current measurements revealed significantly higher magnetoelectric coupling at magnetic fields below 4 T than in pure TbMnO3. This is due to the higher sensitivity of the incommensurably modulated cycloid structure to weak magnetic fields. Detailed analysis of our data confirmed that the ferroelectric polarization is induced by inverse Dzyaloshinskii-Moriya interaction for magnetic field strength up to 4 T, but at higher fields a departure from theoretical predictions is ascertained, giving evidence for an additional, as yet misunderstood, contribution to magnetoelectric coupling. It shows that a small 2% substitution of Mn3+ by Fe3+ has a strong impact on the magnetic structure, promoting the destabilization of the incommensurably modulated magnetic cycloidal structure of $TbMnO_{3}$ in a magnetic field above 5 T. We demonstrate that the magnetoelectric coupling magnitude can be tuned through suitable substitutional elements, even at low level, inducing local lattice distortions with different electronic and magnetic properties.

Such machines have been studied under a variety of additional constraints and generalizations, some of which we apply here. We give the classification of several classes of sortable inversion sequences in terms of pattern avoidance. We are able to provide an exact enumeration of some of the sortable classes in question using both classical approaches and a more recent strategy utilizing generating trees.

description: This paper solves the discretised multiphase flow equations using tools and methods from machine-learning libraries. The idea comes from the observation that convolutional layers can be used to express a discretisation as a neural network whose weights are determined by the numerical method, rather than by training, and hence, we refer to this approach as Neural Networks for PDEs (NN4PDEs). To solve the discretised multiphase flow equations, a multigrid solver is implemented through a convolutional neural network with a U-Net architecture. Immiscible two-phase flow is modelled by the 3D incompressible Navier-Stokes equations with surface tension and advection of a volume fraction field, which describes the interface between the fluids. A new compressive algebraic volume-of-fluids method is introduced, based on a residual formulation using Petrov-Galerkin for accuracy and designed with NN4PDEs in mind. High-order finite-element based schemes are chosen to model a collapsing water column and a rising bubble. Results compare well with experimental data and other numerical results from the literature, demonstrating that, for the first time, finite element discretisations of multiphase flows can be solved using an approach based on (untrained) convolutional neural networks. A benefit of expressing numerical discretisations as neural networks is that the code can run, without modification, on CPUs, GPUs or the latest accelerators designed especially to run AI codes.

description: The first-ever Global Forum on Democratizing Work, on 5-7 October 2021, aimed at building the future of the Democratizing Work movement, across geographical and disciplinary boundaries. A3S hosts a panel on work commodification and its counter-movements, engaging the discussion from the Portuguese context. In recent decades, Portugal has undergone major processes of work commodification and precarization, notably in the aftermath of the global economic crisis, which resulted in heavy austerity measures in the country between 2011 and 2015. Currently, the COVID-19 pandemic has again threatened access to decent and meaningful work, exacerbating inequalities and jeopardizing the lives of the least advantaged. In this context, different initiatives have emerged thriving not to treat work as a commodity and to promote access to employment to all. This panel aims to bring together different perspectives on these processes, looking at public and private initiatives aimed at preserving certain sectors and populations from the laws of the free market; different forms of workers' collective organization; diversity and inclusion of labour market; and employee involvement in companies and workplace democracy. The panel is organized by A3S, a Portuguese Research & Development association, dedicated to the consolidation of alternatives that are participatory, inclusive and sustainable.
Os Arquivos das Casas-Museu em Portugal: um diagnóstico preliminar
Creators: name: Guimarães, Paulo Eduardo

Publisher: name: Cadernos BAD
Year: 2014

description: Este estudo centra-se na relação entre os museus e os seus arquivos, tomando como universo de análise as casas-museu em Portugal. Procede ao reconhecimento dos acervos custodiados por estas entidades e atenta na forma como os seus profissionais compreendem, usam e têm valorizado esse património. Revela-se uma realidade muito diversificada no que diz respeito à existência e características dos acervos, ao seu uso e valorização no contexto do trabalho museal, à percepçãos da sua função pelos técnicos e entidades que as tutelam. Embora os documentos de arquivo integrem as coleções museais e sejam considerados por vezes fundamentais para a atividade do museu, verifica-se, na prática, uma subalternização dos arquivos e da sua função no quadro destas organizações.

Os Catálogos de Nova Geração nas Bibliotecas Universitárias portuguesas: um estado da questão
Creators: name: Cunha, Thiago Mota
name: Leitão, Paulo Jorge Oliveira
Publisher: name: Cadernos BAD
Year: 2014

description: Este estudo teve como principal objetivo analisar o nível de desenvolvimento dos catálogos das bibliotecas universitárias portuguesas e a forma como se aproximam do conceito de Catálogo de Nova Geração. Os dados evidenciam um desencontro entre o serviço de pesquisa disponibilizado e as expectativas de um utilizador universitário. Verificou-se maior aceitação das componentes de nova geração nas universidades públicas em relação às privadas e institutos politécnicos. Ao compararmos os resultados obtidos com estudos estrangeiros é possível afirmar que existe um atraso generalizado no desenvolvimento dos catálogos e que as bibliotecas universitárias portuguesas não estão distantes das suas congéneres internacionais.

O papel social da Biblioteca Universitária na inclusão do indivíduo portador de deficiência visual
Creators: name: Neto, Lígia Maria Fortes Pinto E
Publisher: name: Cadernos BAD
Year: 2014

description: O presente artigo tem como objetivo analisar o papel da biblioteca universitária na inclusão (social e digital) do indivíduo portador de deficiência visual. Pretende-se identificar e analisar a maneira como as bibliotecas universitárias portuguesas estão a desenvolver os seus serviços, no sentido, de responder às necessidades de acesso à informação por parte dos indivíduos portadores de deficiência visual. A escolha do tema justifica-se pela importância de repensar o papel social das bibliotecas universitárias enquanto via de acesso à informação, promovendo a igualdade de oportunidades e permitindo a inclusão de cidadãos portadores de deficiência visual, a promoção das suas competências a par dos seus colegas, e a promoção do sucesso académico dos cidadãos portadores de deficiência visual. Pretende-se apresentar os resultados revelados por um trabalho de investigação, no qual os respondentes identificaram como barreiras no percurso académico dos estudantes com deficiência visual, a dificuldade de acesso à documentação e informação, atitudes discriminatórias de funcionários, inacessibilidade a locais em virtude da existência da barreiras arquitetónicas. Verifica-se que já se encontram implementadas nestas Faculdades boas práticas que indiciam a caminhada na direção do ensino superior inclusivo, porém verifica-se pouca cooperação e partilha de recursos entre os diferentes serviços.

Para uma ética do trabalho académico a partir da literacia de informação
Creators: name: Sanches, Tatiana
Publisher: name: Cadernos BAD
Year: 2014

description: Este artigo propõe-se realizar uma reflexão aprofundada sobre o conceito de ética do trabalho académico no ensino superior, sob o enquadramento conceptual da literacia da informação. Propõe-se que, reconhecendo à partida a sua necessidade de informação, o estudante universitário possa desenvolver um conjunto de práticas de pesquisa, localização, seleção e utilização da informação de forma ética, na prossecução de um trabalho académico. Para fundamentar a reflexão acerca desta componente ética, são realizadas uma revisão de bibliografia e a análise de práticas experienciais já relatadas relativamente à utilização da documentação e da informação, particularmente realizadas em bibliotecas escolares.

Generalized Schroedinger equation in Euclidean field theory
Creators: name: Conrady, Florian

Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We investigate the idea of a "general boundary" formulation of quantum field theory in the context of the Euclidean free scalar field. We propose a precise definition for an evolution kernel that propagates the field through arbitrary spacetime regions. We show that this kernel satisfies an evolution equation which governs its dependence on deformations of the boundary surface and generalizes the ordinary (Euclidean) Schroedinger equation. We also derive the classical counterpart of this equation, which is a Hamilton-Jacobi equation for general boundary surfaces.

description: We characterize the epimorphisms in homotopy type theory (HoTT) as the fiberwise acyclic maps and develop a type-theoretic treatment of acyclic maps and types in the context of synthetic homotopy theory as developed in univalent foundations. We present examples and applications in group theory, such as the acyclicity of the Higman group, through the identification of groups with 0-connected, pointed 1-types. Many of our results are formalized as part of the agda-unimath library.

Oracle-Efficient Hybrid Online Learning with Unknown Distribution

description: We study the problem of oracle-efficient hybrid online learning when the features are generated by an unknown i.i.d. process and the labels are generated adversarially. Assuming access to an (offline) ERM oracle, we show that there exists a computationally efficient online predictor that achieves a regret upper bounded by $\tilde{O}(T^{\frac{3}{4}})$ for a finite-VC class, and upper bounded by $\tilde{O}(T^{\frac{p+1}{p+2}})$ for a class with $α$ fat-shattering dimension $α^{-p}$. This provides the first known oracle-efficient sublinear regret bounds for hybrid online learning with an unknown feature generation process. In particular, it confirms a conjecture of Lazaric and Munos (JCSS 2012). We then extend our result to the scenario of shifting distributions with $K$ changes, yielding a regret of order $\tilde{O}(T^{\frac{4}{5}}K^{\frac{1}{5}})$. Finally, we establish a regret of $\tilde{O}((K^{\frac{2}{3}}(\log|\mathcal{H}|)^{\frac{1}{3}}+K)\cdot T^{\frac{4}{5}})$ for the contextual $K$-armed bandits with a finite policy set $\mathcal{H}$, i.i.d. generated contexts from an unknown distribution, and adversarially generated costs.

description: Let $k$ be an algebraically closed field of positive characteristic $p$. We first classify the $D$-truncations mod $p$ of Shimura $F$-crystals over $k$ and then we study stratifications defined by inner isomorphism classes of these $D$-truncations. This generalizes previous works of Kraft, Ekedahl, Oort, Moonen, and Wedhorn. As a main tool we introduce and study Bruhat $F$-decompositions; they generalize the combined form of Steinberg theorem and of classical Bruhat decompositions for reductive groups over $k$.

Arts Organizing before Precarity and Crisis: The Case of Portuguese Art Workers

description: The outbreak of Covid-19 pandemic has thrown a spotlight on the arts sector worldwide. In Portugal, art workers immediately responded to provide access to culture and citizenship in unconventional places and to adapt to an online presence performing mostly free work. Simultaneously, the sector's structural precarity, that had always existed, has been chronically exposed, also raising the visibility of non- creative professionals in the art worlds (mediators, operators, technicians). On the private sector side, some reference cultural institutions took advantage of the crisis to advance neoliberal agendas of cuts and dismissals. Before the absence of government response to a sector comprised mainly by independent and informal workers, arts professionals started an unprecedented and persistent process of organizing for claiming urgency measures addressing their basic survival needs, but also a consistent policy and statute for the sector. This paper will discuss the changes happening in the Portuguese art worlds from two main standpoints: (1) the role of the State in the (de)regulation and (de)professionalization of the sector, when great responsibility should be exercised in the definition of public policies guaranteeing access to adequate labour rights and social protection to all workers; and (2) the ways arts professionals have been organizing to cope with precarity and crisis, through different forms of collective organization (worker collectives, shared service cooperatives, mutual support systems, inter- organizational collaboration, protest and collective action). The Portuguese case is taken as a case study of a reality that is affecting arts professionals worldwide, demanding a discussion at national and supranational levels.

Short-period AM CVn systems as optical, X-ray and gravitational wave sources

description: We model the population of AM CVn systems in the Galaxy and discuss the detectability of these systems with optical, X-ray and gravitational wave detectors. We concentrate on the short period (P < 1500 s) systems, some of which are expected to be in a phase of direct impact accretion. Using a self-consistent model for the star formation history and radial distribution of stars in the Galaxy plus simple models for the emission of optical and X-ray radiation from the AM CVn systems and interstellar absorption, we derive the sample of short-period AM CVn systems that can be detected in the optical and/or X-ray bands. At the shortest periods the detectable systems are all X-ray sources, some with periods as short as three minutes. At periods above 10 minutes most detectable systems are optical sources. About one third of the X-ray sources are also detectable in the optical band. We also calculate the gravitational wave signal of the short-period AM CVn systems. We find that potentially several thousand AM CVn systems can be resolved by the gravitational wave detector LISA, comparable to the expected number of detached double white dwarfs that can be resolved. We estimate that several hundreds of the AM CVn systems resolvable by LISA, are also detectable in the optical and/or X-ray bands.
