description: O mercado de trabalho em Portugal tem sido profundamente impactado pela COVID-19, apesar das medidas destinadas à manutenção do nível de emprego. Pretende-se neste texto retratar os principais efeitos nocivos que a “primeira vaga” da pandemia teve no (des)emprego e quais as atividades económicas, as categorias sociais e os territórios que por ela foram mais penalizados. Embora estejamos ainda longe dos níveis registados durante a crise anterior, o ritmo a que o desemprego cresceu desde março é muito superior ao que se registou nesse período. Este fenómeno tem atingindo com particular dureza os trabalhadores mais jovens, com qualificações intermédias e vínculos contratuais precárias, sobretudo aqueles que trabalham nos serviços – em particular as atividades associadas ao turismo e ao imobiliário e em setores da indústria especialmente dependentes do mercado externo, como a indústria automóvel ou do calçado. O desemprego aumentou de forma mais acentuada no Algarve. The Portuguese labour market has been severely hit by the COVID-19 pandemic. This paper analysis the main (un)employment impacts of the “first wave” of the pandemic and pinpoints the economic activities, social categories and territories that were most affected by it. Although unemployment figures are still quite bellow the ones reached in the previous crisis, it has been growing quite rapidly. The youth, workers that have intermediate levels of qualification and temporary employees were the most affected, namely those who work in tourism related activities and in sectors more exposed to international trade, such as the automobile and footwear sectors. Unemployment grew at a faster pace in Algarve.

description: A multi-output cost function approach to induced innovation is adopted to analyze the impact of socioeconomic variables and institutional factors on technological change in agriculture. Focusing on the impact of immigration policy and farm mechanization, the study includes variables such as H-2A or guest workers, deportable Mexicans working in agriculture representing the percentage of unauthorized workers, the public and private research expenditures on farm mechanization and other research on agricultural technology. We found that over the 1971-1995 period, the technology was biased toward labor-saving technology, but was capital-neutral. The number of unauthorized workers had no significant effect on cost shares; the number of H-2A workers had a negative effect on the cost share of capital. Both had a positive effect on the revenue share of cereals. Public expenditures on mechanization have a significant impact on reducing the cost share of capital; however, private expenditures on machinery increase the cost share of capital. Using the Morishima elasticity of substitution, we found that labor was a substitute for capital when the price of capital changes, but when the price of labor changes, capital was not necessarily a substitute for labor.

description: Edelstein effect is useful for electric control of magnetic moment. However, Joule heating created by a dissipative current is harmful for its practical applications. In this paper, we investigate two-dimensional noncentrosymmetric superconductors (NCSs) with either $s$-wave or $d$-wave symmetry, and demonstrate that a surface Edelstein effect is significantly enhanced in $d$-wave NCSs. The origin of the enhancement is attributed to surface Majorana states characteristic of gapless spin-singlet superconductors. In the view of superconducting spintronics, this result would give a route to magnetic domain switching by dissipationless supercurrent. We discuss a possible experimental observation in cuprate superconductor heterostructures and heavy fermion superlattices.

description: Low-dimensional ferroelectricity and Dirac materials with protected band crossings are fascinating research subjects. Based on first-principles calculations, we predict the coexistence of spontaneous in-plane polarization and novel 2D emergent fermions in dynamically stable quadruple-layer (QL) XSbO$_2$ (X= Li, Na). Depending on the different polarization configurations, QL-XSbO$_2$ can exhibit unconventional inner-QL ferroelectricity and antiferroelectricity. Both ground states harbor robust ferroelectricity with enhanced spontaneous polarization of 0.56 nC/m and 0.39 nC/m for QL-LiSbO$_2$ and QL-NaSbO$_2$, respectively. Interestingly, the QL-LiSbO$_2$ possesses two other metastable ferroelectric (FE) phases, demonstrating the first 2D example with multiple FE orders. The ground FE phase can be flexibly driven into one of the two metastable FE phases and then into the antiferroelectric (AFE) phase. During this phase transition, several types of 2D fermions emerge, for instance, hourglass hybrid and type-II Weyl loops in the ground FE phase, type-II Weyl fermions in the metastable FE phase, and type-II Dirac fermions in the AFE phase. These 2D fermions are robust under spin-orbit coupling. Notably, two of these fermions, e.g., an hourglass hybrid or type-II Weyl loop, have not been observed before. Our findings identify QL-XSbO$_2$ as a unique platform for studying 2D ferroelectricity relating to 2D emergent fermions.

description: Economic research has produced conflicting findings on the distributional impacts of migrant remittances, and there has been little research on the effects of changes in remittances on poverty. This paper utilizes new data from the Mexico National Rural Household Survey, together with inequality and poverty decomposition techniques, to explore the impacts of remittances on rural inequality and poverty. Our findings suggest that remittances from international migrants become more equalizing (or less unequalizing), as well as more effective at reducing poverty, as the prevalence of migration increases.

description: Incorporation of physical principles in a network-based machine learning (ML) architecture is a fundamental step toward the continued development of artificial intelligence for materials science and condensed matter physics. In this work, as inspired by the Pauling rule, we propose that structure motifs (polyhedral formed by cations and surrounding anions) in inorganic crystals can serve as a central input to a machine learning framework for crystalline inorganic materials. Taking metal oxides as examples, we demonstrated that, an unsupervised learning algorithm Motif2Vec is able to convert the presence of structure motifs and their connections in a large set of crystalline compounds into unique vector representations. The connections among complex materials can be largely determined by the presence of different structure motifs and their clustering information are identified by our Motif2Vec algorithm. To demonstrate the novel use of structure motif information, we show that a motif-centric learning framework can be effectively created by combining motif information with the recently developed atom-based graph neural networks to form an atom-motif dual graph network (AMDNet). Taking advantage of node and edge information on both atomic and motif level, the AMDNet is more accurate than an atom graph network in predicting electronic structure related material properties of metal oxides such as band gaps. The work illustrates the route toward fundamental design of graph neural network learning architecture for complex material properties by incorporating beyond-atom physical principles.

description: Correlated time series are time series that, by virtue of the underlying process to which they refer, are expected to influence each other strongly. We introduce a novel approach to handle such time series, one that models their interaction as a two-dimensional cellular automaton and therefore allows them to be treated as a single entity. We apply our approach to the problems of filling gaps and predicting values in rainfall time series. Computational results show that the new approach compares favorably to Kalman smoothing and filtering.

description: In the simplest scalar-tensor theories, wherein the scalar field is non-minimally coupled to the Ricci scalar, spontaneous scalarization of electrovacuum black holes (BHs) does not occur. This ceases to be true in higher dimensional spacetimes, $d>4$. We consider the scalarization of the higher dimensional Reissner-Nordström BHs in scalar-tensor models and provide results on the zero modes for different $d$, together with an explicit construction of the scalarized BHs in $d=5$, discussing some of their properties. We also observe that a conformal transformation into the Einstein frame maps this model into an Einstein-Maxwel-scalar model, wherein the non-minimal coupling occurs between the scalar field and the Maxwell invariant (rather than the Ricci scalar), thus relating the occurence of scalarization in the two models. Next, we consider the spontaneous scalarization of the Schwarzschild-Tangherlini BH in extended-scalar-tensor-Lovelock gravity in even dimensions. In these models, the scalar field is non-minimally coupled to the $(d/2)^{th}$ Euler density, in $d$ spacetime dimensions. We construct explicitly examples in $d=6,8$, showing the properties of the four dimensional case are qualitatively generic, but with quantitative differences. We compare these higher $d$ scalarized BHs with the hairy BHs in shift-symmetric Horndeski theory, for the same $d$, which we also construct.

description: We aim at gathering information from gravitational interaction in the Universe, at energies where quantum gravity is required. In such a setup a dynamical membrane world in a space-time with scalar bulk matter described by domain walls, as well as a dynamical membrane world in empty Anti de Sitter space-time are analysed. We later investigate the possibility of having shortcuts for gravitons leaving the membrane and returning subsequently. In comparison with photons following a geodesic inside the brane, we verify that shortcuts exist. For late time universes they are small, but for some primordial universes they can be quite effective. In the case of matter branes, we argue that at times just before nucleosynthesis the effect is sufficiently large to provide corrections to the inflationary scenario, especially as concerning the horizon problem and the Cosmological Background Radiation.

A Strong Edge-Coloring of Graphs with Maximum Degree 4 Using 22 Colors

description: In 1985, Erdős and Neśetril conjectured that the strong edge-coloring number of a graph is bounded above by ${5/4}Δ^2$ when $Δ$ is even and ${1/4}(5Δ^2-2Δ+1)$ when $Δ$ is odd. They gave a simple construction which requires this many colors. The conjecture has been verified for $Δ\leq 3$. For $Δ=4$, the conjectured bound is 20. Previously, the best known upper bound was 23 due to Horak. In this paper we give an algorithm that uses at most 22 colors.

description: This study examines the decoupled nature of direct payments and counter-cyclical payments to determine if they have an impact on U.S. rice area harvested. A naïve expectations model was specified, with the results indicating that direct payments are decoupled; however, counter-cyclical are not. Overall, the results indicate that a change in the expected gross margin or counter-cyclical payments would stimulate a supply response in rice production. The lack of a significant amount of time-series data renders results of this analysis as preliminary.

description: We study the tachyon and the RR field sourced by the $(m,n)$ ZZ D-branes in type 0 theories using three methods. We first use the mini-superspace approximation of the closed string wave functions of the tachyon and the RR scalar to probe these fields. These wave functions are then extended beyond the mini-superspace approximation using mild assumptions which are motivated by the properties of the corresponding wave functions in the mini-superspace limit. These are then used to probe the tachyon and the RR field sourced. Finally we study the space time fields sourced by the $(m,n)$ ZZ D-branes using the FZZT brane as a probe. In all the three methods we find that the tension of the $(m,n)$ ZZ brane is $mn$ times the tension of the $(1,1)$ ZZ brane. The RR charge of these branes is non-zero only for the case of both $m$ and $n$ odd, in which case it is identical to the charge of the $(1,1)$ brane. As a consistency check we also verify that the space time fields sourced by the branes satisfy the corresponding equations of motion.

We extrapolate the form factors to $Q^2 = 0$, corresponding to a real photon, using quark-model-inspired functions. Finally, comparison is made with photocouplings extracted from the measured radiative widths, where known. Our preliminary results find photocouplings commensurate with these experimentally extracted values.

Rhodolaena altivola is a small tree occurring in low to mid-elevation humid forest along the north-central part of the east coast (Fig. 1). A single specimen with locality data indicating "Didy", situated farther inland, was probably in fact collected much nearer to the coast. This species is distinguished by large, ovate, coriaceous leaves with an acuminate apex and more or less rounded base (closely resembling those of Schizolaena laurina Baill.), and glabrous, shiny sepals. As in R. acutifolia, the leaves dry maroonbrownish, the secondary veins are usually obscure on the dull upper surface, and the tertiary veins form a dense reticulated network on the lower surface. Rhodolaena altivola has recently been collected at Analalava west of Foulpointe, and at Tampolo STF.

The body's tale subtitle : a counter history : schooling space and imperial subjectivities
Creators: name: Chapman, Valerie-Lee
Publisher: name: University of British Columbia
Year: 2009

description: The body's tale traces the genealogy of my educated body. I used postcolonial autoethnographic methods in field research at sites of my schooling, combined with selfwriting, to come to "know myself through askesis. The Tale uses poetry, narratives, academic prose and visuals, as well as liberal doses of irony; it is set in the temporal frame of an academic Book of Hours. A feminist and Foucaultian counterhistory, the Tale re-presents my education, in parodic and dis-associative ways, as a discursive and a colonizing practice which resulted in the (frequently willing) subjectification of myself as female, heterosexual, upper middle class, white and Imperial. My subjectification began at Home, was perfected at school, and reinforced in university education. Capacitive and communicative power was literally applied to me/my body to induce a self-understanding of an essentially flawed interior with a "natural" sexual identity. My counter-memories illustrate how I internalized the effects of pastoral power, learned to interpellate liminality, and to police the spatialized ingestion and abjection of identity creating substances. Profound early training limits my body's ability to consciously subvert some subjectivities, like gender and race, even though I understand these to be performative. Where power relations existed in educational settings, then, as an active agent, "fields of possibilities" for reworking subjectivities opened up to me, and especially in heterotopic and "liminai" places/contact zones like toilets, bathrooms, cemeteries, and hallways. I tell stories of frequently futile resistance struggles against dominating power, yet, as this power needs to be constantly applied to subjects, iteration contains the potential for its failure. Resistance to communicative power is possible through re-writing the self, and in correspondence with others; the Tale chronicles a parallel (largely unconscious and unplanned) body project, which successfully re-inscribed some subjectivities, simultaneously with the writing of the academic Tale, thus demonstrating the productivity of power relations. University adult educators can become aware of: how we use power in education; the possibilities for change inherent in finding out and then resisting what "we are"; how subjectivities shift across spaces; and, how to counter our learned tendency to "swarm" out as colonizers/disciplinary mechanisms. We can practice an ethics of caring for the self, rather than caring for others—a discourse which cloaks pastoral power—where our aim is self-knowledge through writing and counter remembering.

description: Quantum information processing (QIP) offers the promise of being able to do things that we cannot do with conventional technology. Here we present a new route for distributed optical QIP, based on generalized quantum non-demolition measurements, providing a unified approach for quantum communication and computing. Interactions between photons are generated using weak non-linearities and intense laser fields--the use of such fields provides for robust distribution of quantum information. Our approach requires only a practical set of resources, and it uses these very efficiently. Thus it promises to be extremely useful for the first quantum technologies, based on scarce resources. Furthermore, in the longer term this approach provides both options and scalability for efficient many-qubit QIP.

description: Focused electron beam induced deposition (FEBID) is a powerful technique for 3D-printing of complex nanodevices. However, for resolutions below 10 nm, it struggles to control size, morphology and composition of the structures, due to a lack of molecular-level understanding of the underlying irradiation-driven chemistry (IDC). Computational modelling is a tool to comprehend and further optimise FEBID-related technologies. Here we utilise a novel multiscale methodology which couples Monte Carlo simulations for radiation transport with irradiation-driven molecular dynamics for simulating IDC with atomistic resolution. Through an in depth analysis of W(CO)$_6$ deposition on SiO$_2$ and its subsequent irradiation with electrons, we provide a comprehensive description of the FEBID process and its intrinsic operation. Our analysis reveals that these simulations deliver unprecedented results in modelling the FEBID process, demonstrating an excellent agreement with available experimental data of the simulated nanomaterial composition, microstructure and growth rate as a function of the primary beam parameters.

The use of Heavy Quark Symmetry (HQS) provides with an important simplification of the non relativistic three body problem which can be solved by means of a simple variational approach. This scheme is able to reproduce previous results obtained with more involved Faddeev calculations. The resulting wave functions are parametrized in a simple manner, and can be used to calculate further observables.

description: Using a unique farm-level panel data set derived from three U.S. Agricultural Censuses, we estimate a Cox proportional hazard model to examine the effect of direct government payments on the survival of farm businesses, paying particular attention to the differential effect of payments across farm size categories. For identification the study exploits variation in payments resulting from historical differences in 'base acreage' in otherwise similar farms. We find an increase in government payments has a small but statistically significant positive effect on the rate of farm survival, and the magnitude of this effect increases with farm size.

description: The electronic structure in unconventional superconductors holds a key to understand the momentum-dependent pairing interactions and the resulting superconducting gap function. In superconducting Fe-based chalcogenides, there have been controversial results regarding the importance of the $k_z$ dependence of the electronic dispersion, the gap structure and the pairing mechanisms of iron-based superconductivity. Here, we present a detailed investigation of the van der Waals interaction in FeSe and its interplay with magnetic disorder and real space structural properties. Using density functional theory we show that they need to be taken into account upon investigation of the 3-dimensional effects, including non-trivial topology, of FeSe$_{1-x}$Te$_x$ and FeSe$_{1-x}$S$_x$ systems. In addition, the impact of paramagnetic (PM) disorder is considered within the spin-space average approach. Our calculations show that the PM relaxed structure supports the picture of different competing ordered magnetic states in the nematic regime, yielding magnetic frustration.

description: In der Schweiz gibt es gerade in evangelisch-reformierten Kantonen überproportional viele evangelikale Pflegefamilien. Der Evangelikalismus ist der breiten schweizer Bevölkerung kaum bekannt und das wenig Bekannte ist regelmässig Inhalt kontroverser Diskussionen. Diese Situation löst bei den Sozialarbeitenden ungute Gefühle aus. Diese Arbeit soll der Frage nachgehen, wie sich eine Platzierung in einer evangelikalen Pflegefamilie auf die pflegekindsspezifischen Bedürfnisse und Entwicklungsaufgaben in der Adoleszenzphase, mit Fokus auf dem Kindeswohl, auswirken kann. Dazu sollen in den theoretischen Teilen dieser Arbeit das Pflegekinderrecht, der Pflegekinderbereich, die Identitätsentwicklung in der Adoleszenz und der Evangelikalismus im Kontext der Fragestellung erläutert werden. Das Ziel dieser Arbeit ist es, aufzuzeigen, welche Umstände für eine gelingende Pflegebeziehung in einer evangelikalen Pflegefamilie von den Sozialarbeitenden berücksichtigt und abgeklärt werden müssen. Die theoretischen Grundlagen halten sich einerseits an repräsentative Studien für die Schweiz zum Evangelikalismus und Pflegekinderbereich, andererseits an den aktuellen Stand der Wissenschaft zur psychosozialen Identitätsentwicklung. Die Ergebnisse dieser Literaturstudie zeigen auf, dass sich der Glaube problematisch auf die psychische Entwicklung (u.a. die Identitätsbildung) des Pflegekindes auswirken kann und deshalb von der Sozialen Arbeit mehr Aufmerksamkeit bedarf. Um eine für das Kindeswohl günstige Platzierung sicherzustellen, benötigt es die Aufklärung durch Professionelle der Sozialen Arbeit im Pflegekinderbereich, welche mit einer guten Kenntnis über den Evangelikalismus ausgestattet sind.

description: The results from 2.5-dimensional Particle-in-Cell simulations for the interaction of a picosecond-long ignition laser pulse with a plasma pellet of 50-$μm$ diameter and 40 critical density are presented. The high density pellet is surrounded by an underdense corona and is isolated by a vacuum region from the simulation box boundary. The laser pulse is shown to filament and create density channels on the laser-plasma interface. The density channels increase the laser absorption efficiency and help generate an energetic electron distribution with a large angular spread. The combined distribution of the forward-going energetic electrons and the induced return electrons is marginally unstable to the current filament instability. The ions play an important role in neutralizing the space charges induced by the the temperature disparity between different electron groups. No global coalescing of the current filaments resulted from the instability is observed, consistent with the observed large angular spread of the energetic electrons.

description: Most recently, F-diamane monolayer was experimentally realized by the fluorination of bilayer graphene. In this work we elaborately explore the electronic and thermal conductivity responses of diamane lattices with homo or hetero functional groups, including: non-Janus C2H, C2F and C2Cl diamane and Janus counterparts of C4HF, C4HCl and C4FCl. Noticeably, C2H, C2F, C2Cl, C4HF, C4HCl and C4FCl diamanes are found to show electronic diverse band gaps of, 3.86, 5.68, 2.42, 4.17, 0.86, and 2.05 eV, on the basis of HSE06 method estimations. The thermal conductivity of diamane nanosheets was acquired using the full iterative solutions of the Boltzmann transport equation, with substantially accelerated calculations by employing machine-learning interatomic potentials in obtaining the anharmonic force constants. According to our results, the room temperature lattice thermal conductivity of graphene and C2H, C2F, C2Cl, C4HF, C4HCl and C4FCl diamane monolayers are estimated to be 3636, 1145, 377, 146, 454, 244 and 196 W/mK, respectively. The underlying mechanisms resulting in significant effects of functional groups on the thermal conductivity of diamane nanosheets were thoroughly explored. Our results highlight the substantial role of functional groups on the electronic and thermal conduction responses of diamane nanosheets.

description: Recently, discussion had reemerged over the value of integrated pest and crop management training, through intensive approaches such as farmer field schools or participatory training, as a development approach (Feder et al, 2004). This paper develops a model of human capital accumulation through participatory research and tests several hypotheses on the effectiveness of this approach to increase the adoption of soil conservation and fertility management innovations and improve farm productivity in southeast Asia. Bivariate Probit models with treatment effects are estimated using full information maximum likelihood (Evans and Schwab, 1995: Trost and Lee, 1984) and covariates related to changes in land allocation and productivity, measured before project and after project intervention, are investigates. We follow Greene (1998) to control for simultaneity between adoption and impact by using the predicted adoption decision from the second set of regressions to calculate productivity differentials. Overall, we find that treatment affects associated with the participatory research activities are significant and positive in explaining the differential adoption rates of intercropping, hedgerows, contour ridging, the usage of farm yard manure and chemical fertilizer. The positive relationship between the adoption of soil conservation and fertility management techniques and participation, given very limited productivity impact, may indicated the "value" of the participatory approach to illustrate the social costs of land degradation, sensitize participants towards internalizing these costs, and demonstrate the importance of long-run strategies to preserve land productivity, or both. Secondly, we find that there are additional benefits to participatory research activities that are not embodied in the adoption of soil conservation or fertility management techniques.

description: The merging procedure of tree-level matrix elements with the subsequent parton shower as implemented in SHERPA will be studied for the example of W boson pair production at the Fermilab Tevatron. Comparisons with fixed order calculations at leading and next-to-leading order in the strong coupling constant and with other Monte Carlo simulations validate once more the impact and the quality of the merging algorithm and its implementation.

description: The initial-final mass relation (IFMR) links the birth mass of a star to the mass of the compact remnant left at its death. While the relevance of the IFMR across astrophysics is universally acknowledged, not all of its fine details have yet been resolved. A new analysis of a few carbon-oxygen white dwarfs in old open clusters of the Milky Way led us to identify a kink in the IFMR, located over a range of initial masses, $1.65 \lesssim M_{\rm i}/M_{\odot} \lesssim 2.10$. The kink's peak in WD mass of $\approx 0.70-0.75 \, M_{\odot}$ is produced by stars with $M_{\rm i} \simeq 1.8 - 1.9 \, M_{\odot}$, corresponding to ages of about $1.8 - 1.7 $ Gyr. Interestingly, this peak coincides with the initial mass limit between low-mass stars that develop a degenerate helium core after central hydrogen exhaustion, and intermediate-mass stars that avoid electron degeneracy. We interpret the IFMR kink as the signature of carbon star formation in the Milky Way. This finding is critical to constraining the evolution and chemical enrichment of low-mass stars, and their impact on the spectrophotometric properties of galaxies.

description: We consider a disordered two-dimensional electron gas with spin-orbit coupling placed in a perpendicular magnetic field and calculate the magnitude and direction of the electric-field-induced spin polarization. We find that in strong magnetic fields the polarization becomes an oscillatory function of the magnetic field and that the amplitude of these oscillations is parametrically larger than the polarization at zero magnetic field. We show that the enhanced amplitude of the polarization is a consequence of strong electron-hole asymmetry in a quantizing magnetic field.

description: The correlated electron material CePd$_2$P$_2$ crystallizes in the ThCr$_2$Si$_2$ structure and orders ferromagnetically at 29 K. Lai et al. [Phys. Rev. B 97, 224406 (2018)] found evidence for a ferromagnetic quantum critical point induced by chemical compression via substitution of Ni for Pd. However, disorder effects due to the chemical substitution interfere with a simple analysis of the possible critical behavior. In the present work, we examine the temperature - pressure - magnetic field phase diagram of single crystalline CePd$_2$P$_2$ to 25 GPa using a combination of resistivity, magnetic susceptibility, and x-ray diffraction measurements. We find that the ferromagnetism appears to be destroyed near 12 GPa, without any change in the crystal structure.
