description: Vivemos numa era em grande transformação económica e social. O uso exponencial da tecnologia de informação e comunicação, tem contribuído de forma acelerada para grandes mudanças na vida em sociedade, no modo como trabalhamos e como os negócios são organizados e conduzidos. Esta transformação digital representa uma oportunidade para a Gestão de Recursos Humanos, desafiando o modo como podem oferecer soluções e serviços de RH, por exemplo, por meio de novas plataformas digitais e de outros aplicativos (Stephan, Uzawa, Volini, Walsh, & Yoshida, 2016). A automatização de algumas tarefas administrativas rotineiras no departamento de recursos humanos pode trazer melhorias para a organização no seu todo, possibilitando que os gestores e líderes aumentem o tempo que dedicam à análise de dados, à procura de soluções de problemas e ao desenvolvimento de outras atividades que capacitem as pessoas e promovam o seu bem-estar (autor, 2019). Na presente comunicação pretende-se apresentar os principais resultados de um projeto, em curso, sobre práticas de gestão e desenvolvimento de recursos humanos e processos organizacionais no quadro das pequenas e médias empresas (PME) em Portugal, em concreto do inquérito por questionário aplicado a um conjunto de 129 PME. A análise, assumidamente exploratória dos dados, aponta para um ainda parco recurso a novas plataformas digitais e outros aplicativos, levando-nos a questionar o caminho ainda a percorrer por estes contextos organizacionais e de emprego específicos – as PME – no atual contexto de transformação digital.

description: We discuss the technique of Wide-field imaging as it applies to Very Long Baseline Interferometry (VLBI). In the past VLBI data sets were usually averaged so severely that the field-of-view was typically restricted to regions extending a few hundred milliarcseconds from the phase centre of the field. Recent advances in data analysis techniques, together with increasing data storage capabilities, and enhanced computer processing power, now permit VLBI images to be made whose angular size represents a significant fraction of an individual antenna's primary beam. This technique has recently been successfully applied to several large separation gravitational lens systems, compact Supernova Remnants in the starburst galaxy M82, and two faint radio sources located within the same VLA FIRST field. It seems likely that other VLBI observing programmes might benefit from this wide-field approach to VLBI data analysis. With the raw sensitivity of global VLBI set to improve by a factor 4-5 over the coming few years, the number of sources that can be detected in a given field will rise considerably. In addition, a continued progression in VLBI's ability to image relatively faint and extended low brightness temperature features (such as hot-spots in large-scale astrophysical jets) is also to be expected. As VLBI sensitivity approaches the $μ$Jy level, a wide-field approach to data analysis becomes inevitable.

description: Layered material structures play a key role in enhancing electron-electron interactions to create correlated metallic phases that can transform into unconventional superconducting states. The quasi-two-dimensional electronic properties of such compounds are often inferred indirectly through examination of their bulk properties. Here we use scanning tunneling microscopy and spectroscopy to directly probe in cross section the quasi-two-dimensional correlated electronic states of the heavy fermion superconductor CeCoIn5. Our measurements reveal the strong confined nature of heavy quasi-particles, anisotropy of tunneling characteristics, and layer-by-layer modulated behavior of the precursor pseudogap gap phase in this compound. Examining the interlayer coupled superconducting state at low temperatures, we find that the orientation of line defects relative to the d-wave order parameter determines whether in-gap states form due to scattering. Spectroscopic imaging of the anisotropic magnetic vortex cores directly characterizes the short interlayer superconducting coherence length and shows an electronic phase separation near the upper critical in-plane magnetic field, consistent with a Pauli-limited first-order phase transition into a pseudogap phase.

Environment and Energy Injection Effects in GRB Afterglows
Creators: name: Dai, Z. G.
name: Lu, T.
Publisher: name: arXiv
Year: 1999
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In a recent paper (Dai & Lu 1999), we have proposed a simple model in which the steepening in the light curve of the R-band afterglow of the gamma-ray burst (GRB) 990123 is caused by the adiabatic shock which has evolved from an ultrarelativistic phase to a nonrelativistic phase in a dense medium. We find that such a model is quite consistent with observations if the medium density is about $3\times 10^6 {\rm cm}^{-3}$. Here we discuss this model in more details. In particular, we investigate the effects of synchrotron self absorption and energy injection. A shock in a dense medium becomes nonrelativistic rapidly after a short relativistic phase. The afterglow from the shock at the nonrelativistic stage decays more rapidly than at the relativistic stage. Since some models for GRB energy sources predict that a strongly magnetic millisecond pulsar may be born during the formation of GRB, we discuss the effect of such a pulsar on the evolution of the nonrelativistic shock through magnetic dipole radiation. We find that after the energy which the shock obtains from the pulsar is much more than the initial energy of the shock, the afterglow decay will flatten significantly. When the pulsar energy input effect disappears, the decay will steepen again. These features are in excellent agreement with the afterglows of GRB 980519, GRB 990510 and GRB 980326. Furthermore, our model fits very well all the observational data of GRB 980519 including the last two detections.

Strong Extended Technicolour Interactions and the $Zb\bar{b}$ Vertex

Publisher: name: arXiv

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: LEP precision measurements of the $Zb\bar{b}$ vertex coupling are sufficiently accurate to see the non-oblique corrections from the heavy gauge boson responsible for the large top mass in standard extended tecnicolour models. If the ETC couplings are strong the techni-fermion condensate may be enhanced by several orders of magnitude allowing a top mass of order 150GeV to be obtained for large values of the ETC breaking scale sufficient to supress the ETC contribution to the $Zb{\bar b}$ vertex. In this letter we investigate the degree of fine tuning of the ETC coupling required in a realistic model. We conclude that the fine tuning need only be of order $10\%$.

description: A method is proposed to extend the hard scattering picture of Brodsky and Lepage to transitions between hadrons with orbital angular momentum l=0 and l=1. The use of covariant spin wave functions turns out to be very helpful in formulating that method. As a first application we construct a light-cone wave function of the nucleon resonance $N^*(1535)$ in the quark-diquark picture. Using this wave function and the extended hard scattering picture, the $N$--$N^*$ transition form factors are calculated at large momentum transfer and the results compared to experimental data. As a further application of our method we briefly discuss the $π$--$a_1$ form factors in an appendix.

New optimization scheme to obtain interaction potentials for oxide glasses

description: We propose a new scheme to parameterize effective potentials that can be used to simulate atomic systems such as oxide glasses. As input data for the optimization, we use the radial distribution functions of the liquid and the vibrational density of state of the glass, both obtained from ab-initio simulations, as well as experimental data on the pressure dependence of the density of the glass. For the case of silica, we find that this new scheme facilitates finding pair potentials that are significantly more accurate than previous ones even if the functional form is the same, thus demonstrating that even simple two-body potentials can be superior to more complex three-body potentials. We have tested the new potential by calculating the pressure dependence of the elastic moduli and find a good agreement with the corresponding experimental data.

Internal shocks in blazar jets

subject: FOS: Physical sciences

description: The discovery of strong gamma-ray and hard X-ray emission and the results from various multifrequency campaigns have disclosed new aspects of the blazar phenomenology, leading to a much more robust understanding of the mechanisms underlying their emission, and offering clues for the energetics of their relativistic jets. I review these aspects, and propose that all the diversity in the blazar phenomenology depends on only one parameter. I also suggest that some of the blazar characteristics can be explained by the internal shock scenario, as proposed to explain the emission from gamma-ray bursts.

description: 'Oumuamua was discovered passing through our Solar System on a hyperbolic orbit. It presents an apparent contradiction, with colors similar to those of volatile-rich Solar System bodies but with no visible outgassing or activity during its close approach to the Sun. Here we show that this contradiction can be explained by the dynamics of planetesimal ejection by giant planets. We propose that 'Oumuamua is an extinct fragment of a comet-like planetesimal born in a planet-forming disk that also formed Neptune- to Jupiter-mass giant planets. On its pathway to ejection 'Oumuamua's parent body underwent a close encounter with a giant planet and was tidally disrupted into small pieces, similar to comet Shoemaker-Levy 9's disruption after passing close to Jupiter. We use dynamical simulations to show that 0.1-1% of cometary planetesimals undergo disruptive encounters prior to ejection. Rocky asteroidal planetesimals are unlikely to disrupt due to their higher densities. After disruption, the bulk of fragments undergo enough close passages to their host stars to lose their surface volatiles and become extinct. Planetesimal fragments such as 'Oumuamua contain little of the mass in the population of interstellar objects but dominate by number. Our model makes predictions that will be tested in the coming decade by LSST.

description: We report new photometry of populous intermediate-age clusters in the SMC using the {\sl Hubble Space Telescope}. In contrast to the accepted picture, these clusters appear to have formed in two brief intervals, one $8\pm 2$ Gyr ago, and a more recent burst $2\pm 0.5$ Gyr ago. When the ridgelines of the four clusters (NGC 339, 361, 416, and Kron 3) in the 8 Gyr burst are aligned, the dispersion in turnoff luminosities is $<0.2$ mag, corresponding to a maximum age spread of $\pm 0.7$ Gyr. When the ridgelines of three clusters (NGC 152, 411, and 419) in the 2 Gyr burst are aligned, the maximum dispersion of 0.2 mag in turnoff luminosity corresponds to a permitted age spread of $\pm 0.2$ Gyr. Within each group of clusters, the entire cluster loci (including red giant branches and clumps) are nearly identical, consistent with indistinguishable metallicities and ages. In contrast to the wide dispersion in ages previously reported in the literature, our sample with more precise photometry and age measurements supports a burst-punctuated rather than a continuous cluster formation history for the 2 Gyr and 8 Gyr SMC clusters.

Ethical behaviour of firms and corruption – a cluster analysis

Year: 2019

description: Corporate ethics and low corruption in the public sector are crucial to business development in an increasingly global world. Business organisations cannot disregard business ethics in order to increase performance in a society where clients are more demanding of the reputation and transparency of organisations. But business ethical behaviour is also very related with the political structures. Countries with better governance, where authority is exercised for the common good, the agents have confidence and respect the rules of the society, the government implement sound policies and regulations that allows the development of the private sector, that have high levels of public services' quality, that are politically stable, promote political, civil and human rights, and are less corrupt create a sound business environment propitiator of higher standards of corporate ethics. When the public sector is corrupt there is little incentive to maintain high standards of business ethics. In this context the purpose of this paper is to analyse the ethical behaviour of firms and corruption in the public sector, to group countries according to these indicators and to investigate the characteristics of these clusters.

The Asymmetry of Galaxies: Physical Morphology for Nearby and High Redshift Galaxies

description: We present a detailed study of rotational asymmetry in galaxies for both morphological and physical diagnostic purposes. An unambiguous method for computing asymmetry is developed, robust for both distant and nearby galaxies. By degrading real galaxy images, we test the reliability of this asymmetry measure over a range of observational conditions, e.g. spatial resolution and signal-to-noise (S/N). Compared to previous methods, this new algorithm avoids the ambiguity associated with choosing a center by using a minimization method, and successfully corrects for variations in S/N. There is, however, a strong relationship between the rotational asymmetry and physical resolution (distance at fixed spatial resolution); objects become more symmetric when less well-resolved. We further investigate asymmetry as a function of galactic radius an rotation. We find the asymmetry index has a strong radial dependence that differs vastly between Hubble types. As a result, a meaningful asymmetry index must be specified within a well-defined radius representative of the physical galaxy scale. We enumerate several viable alternatives, which excludes the use of isophotes. Asymmetry as a function of angle (A[phi]) is also a useful indicator of ellipticity and higher-order azimuthal structure. In general, we show the power of asymmetry as a morphological parameter lies in the strong correlation with (B-V) color for galaxies undergoing normal star formation, spanning all Hubble types from ellipticals to irregular galaxies. Interacting galaxies do not fall on this asymmetry-color ``fiducial sequence,'' as these galaxies are too asymmetric for their color. We propose to use this fact to distinguish between `normal' galaxies and galaxies undergoing an interaction or merger at high redshift.

description: We use transport and inelastic neutron scattering measurements to investigate single crystals of iron pnictide BaFe$_{2-x}$Ni$_{x}$As$_{2}$ ($x=0,0.03$), which exhibit a tetragonal-to-orthorhombic structural transition at $T_s$ and stripe antiferromagnetic order at $T_N$ ($T_s\geq T_N$). Using a tunable uniaxial pressure device, we detwin the crystals and study their transport and spin excitation properties at antiferromagnetic wave vector $S_1(1,0)$ and its 90$^\circ$ rotated wave vector $S_2(0,1)$ under different pressure conditions. We find that uniaxial pressure necessary to detwin and maintain single domain orthorhombic antiferromagnetic phase of BaFe$_{2-x}$Ni$_{x}$As$_{2}$ induces resistivity and spin excitation anisotropy at temperatures above zero pressure $T_s$. In uniaxial pressure-free detwinned sample, spin excitation anisotropy between $S_1(1,0)$ and $S_2(0,1)$ first appear in the paramagnetic orthorhombic phase below $T_s$. These results are consistent with predictions of spin nematic theory, suggesting the absence of structural or nematic phase transition above $T_s$ in iron pnictides.

description: We experimentally study the influence of wall roughness on bubble drag reduction in turbulent Taylor-Couette flow, i.e.\ the flow between two concentric, independently rotating cylinders. We measure the drag in the system for the cases with and without air, and add roughness by installing transverse ribs on either one or both of the cylinders. For the smooth wall case (no ribs) and the case of ribs on the inner cylinder only, we observe strong drag reduction up to $DR=33\%$ and $DR=23\%$, respectively, for a void fraction of $α=6\%$. However, with ribs mounted on both cylinders or on the outer cylinder only, the drag reduction is weak, less than $DR=11\%$, and thus quite close to the trivial effect of reduced effective density. Flow visualizations show that stable turbulent Taylor vortices --- large scale vortical structures --- are induced in these two cases, i.e. the cases with ribs on the outer cylinder. These strong secondary flows move the bubbles away from the boundary layer, making the bubbles less effective than what had previously been observed for the smooth-wall case. Measurements with counter-rotating smooth cylinders, a regime in which pronounced Taylor rolls are also induced, confirm that it is really the Taylor vortices that weaken the bubble drag reduction mechanism. Our findings show that, although bubble drag reduction can indeed be effective for smooth walls, its effect can be spoiled by e.g.\ biofouling and omnipresent wall roughness, as the roughness can induce strong secondary flows.

description: Data obtained in the 1950-1955 Palomar campaign for the discovery of classical novae in M81 are set out in detail. Positions and apparent B magnitudes are listed for the 23 novae that were found. There is modest evidence that the spatial distribution of the novae does not track the B brightness distribution of either the total light or the light beyond an isophotal radius that is $70\arcsec$ from the center of M81. The nova distribution is more extended than the aforementioned light, with a significant fraction of the sample appearing in the outer disk/spiral arm region. We suggest that many (perhaps a majority) of the M81 novae that are observed at any given epoch (compared with say $10^{10}$ years ago) are daughters of Population I interacting binaries. The conclusion that the present day novae are drawn from two population groups, one from low mass white dwarf secondaries of close binaries identified with the bulge/thick disk population, and the other from massive white dwarf secondaries identified with the outer thin disk/spiral arm population, is discussed. We conclude that the M81 data are consistent with the two population division as argued previously from (1) the observational studies on other grounds by Della Valle et al. (1992, 1994), Della Valle & Livio (1998), and Shafter et al. (1996) of nearby galaxies, (2) the Hatano et al. (1997a,b) Monte Carlo simulations of novae in M31 and in the Galaxy, and (3) the Yungelson et al. (1997) population synthesis modeling of nova binaries. Two different methods of using M81 novae as distance indicators give a nova distance modulus for M81 as $(m-M)_0 = 27.75$, consistent with the Cepheid modulus that is the same value.

description:
( +)-Catechin is a type of polyphenolic compound, and it is enriched in fruits, plants, and various beverages. Polyphenolic compounds also play an important role in the human diet. Many scientists, especially wine researchers, have proposed that(+)catechin and its polymers could have many positive health effects. Thus, it is essential to learn more about (+)-catechin and other polyphenolics. Presently, high performance liquid chromatography is the only method to detect ( + )-catechin levels in human blood serum, but this method has the high cost of instrumentation and does not provide good sensitivity. The objective of this project is to develop a high sensitivity, low cost, method to detect ( + )-catechin in serum.

A diazonium coupling reaction and a water soluble carbodiimide reaction were performed to prepare an antigen, (+)-catechin-bovine serum albumin. Approximately 12 mL of gamma globulin was isolated from whole antiserum, and the final concentration of gamma globulin was determined to be 2. 81 mg/mL. From the electrophoresis densitometry, the isolated gamma globulin was found to have the purity of98.9%. Polystyrene microtubes were used as the solid phase for immobilization of antibodies, and the concentrated antibody was diluted to I ng/mL for coating onto the solid phase. The nonlabeled-antigen and the labeled-antigen were allowed to compete for the binding of the immobilized antibodies for I hour, then the excess labeled and nonlabeled antigens were washed away from the solid phase with IO mM phosphate buffer saline and deionizd water.

The detection limit of the ( +)-catechin enzyme immunoassay was determined to be 7 ± 1.4 pM, and the coefficient of variation for the intra-assay precision study performed at (+)-catechin concentrations of 10 pM and 100 pM were found to be 13 .1 % and 11. 4 %, respectively.

The recovery of (+)-catechin from serum was determined to be 71.3% ± 3%, by the recommendation of the International Federation of Clinical Chemistry. The developed EIA method exhibits a linear range of 10 to 100 pM for the catechin standard solutions.

The developed EIA method exhibits a sensitivity that is 5 orders of magnitude higher than the conventional HPLC method. Furthermore, the cost of the instrumentation for the EIA method is one tenth that of HPLC method. Finally, the developed method is capable of analyzing multiple samples within 60 minutes whereas HPLC method can only analyze 4 samples within 60 minutes.

This newly developed EIA method can now be applied to enhance the study of the health effects of (+)-catechin on human body, especially wine drinkers. In addition, other EIA methods to detect flavanoids can also be developed based on the concept of the current EIA method.

description: The massive one-loop {\it QCD} corrections to the production cross sections of We present the massive one-loop {\it QCD} corrections to the production cross sections of polarized quarks in the annihilation process $e^+e^-\to q\bar{q}(g)$ for bottom, top, and charm quarks. From the full analytical expressions for the production cross sections, Schwinger-type interpolation formulae for all parity-parity combinations $(VV, V\!A, AA)$ are derived. The parity-odd interpolation formula contains the correct limit for vanishing quark masses taking into account a residual coupling of left- and right-chiral states in the massless theory. Numerical results for the total cross section and the longitudinal spin polarization demonstrate the accuracy of the interpolation formulae.

description: A responsabilidade social externa das organizações de caracter social é visível e imprescindível na organização dos cuidados às pessoas mais velhas. Estas organizações necessitam de desenvolver a sua responsabilidade social interna, incidindo sobre a necessidade de melhorar os processos que cuidam das suas pessoas, dos seus trabalhadores, ao mesmo tempo que as preparam para melhor providenciar serviços às pessoas mais velhas. Os crescentes e multifacetados desafios associados ao envelhecimento impelem estas organizações para uma necessidade de inovar e de desenvolver novos processos de trabalho alicerçados por trabalhadores competentes e com capacidade de construir competência coletiva. Este estudo teve como objetivo explorar a perceção sobre as competências individuais e a relevância da inovação percebida nas organizações sociais. Adicionalmente, o estudo pretende na prática perceber a aplicabilidade do modelo teórico de Lima e Silva (2015).

description: These notes are the English version of the paper "Hyperbolicité du graphe des rayons et quasi-morphismes sur un gros groupe modulaire". The mapping class group Gamma of the complement of a Cantor set in the plane arises naturally in dynamics. We show that the ray graph, which is the analog of the complex of curves for this surface of infinite type, has infinite diameter and is hyperbolic. We use the action of Gamma on this graph to find an explicit non trivial quasimorphism on Gamma and to show that this group has infinite dimensional second bounded cohomology. Finally we give an example of a hyperbolic element of Gamma with vanishing stable commutator length. This carries out a program proposed by Danny Calegari.

description: We present the Bright SHARC (Serendipitous High-Redshift Archival ROSAT Cluster) Survey, which is an objective search for serendipitously detected extended X-ray sources in 460 deep ROSAT PSPC pointings. The Bright SHARC Survey covers an area of 178.6 sq.deg and has yielded 374 extended sources. We discuss the X-ray data reduction, the candidate selection and present results from our on-going optical follow-up campaign. The optical follow-up concentrates on the brightest 94 of the 374 extended sources and is now 97% complete. We have identified thirty-seven clusters of galaxies, for which we present redshifts and luminosities. The clusters span a redshift range of 0.0696

description: We have studied collisions between tetraphenylporphyrin cations and He or Ne at center-of-mass energies in the 50-110 eV range. The experimental results were interpreted in view of Density Functional Theory calculations of dissociation energies and classical Molecular Dynamics simulations of how the molecules respond to He/Ne impact. We demonstrate that prompt atom knockout strongly contributes to the total destruction cross sections. Such impulse driven processes typically yield highly reactive fragments and are expected to be important for collisions with any molecular system in this collision energy range, but have earlier been very difficult to isolate for biomolecules.

description: Interior models of Jupiter and Saturn are calculated and compared in the framework of the three-layer assumption, which rely on the perception that both planets consist of three globally homogeneous regions: a dense core, a metallic hydrogen envelope, and a molecular hydrogen envelope. Within this framework, constraints on the core mass and abundance of heavy elements (i.e. elements other than hydrogen and helium) are given by accounting for uncertainties on the measured gravitational moments, surface temperature, surface helium abundance, and on the inferred protosolar helium abundance, equations of state, temperature profile and solid/differential interior rotation.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Electroweak Strings Produce Baryons

Year: 1994
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose a new mechanism to generate baryons. Electroweak strings produced at the electroweak phase transition will introduce anomalous currents through interactions of the strings with the background electromagnetic field and through changes in the helicity of the string network. These anomalous currents will produce fluctuations in the baryon and lepton number. We show that in the two-Higgs model corrections to the action coming from the effective potential introduce a bias in the baryon asymmetry that leads to a net baryon number production.
