Perceived employability in a situation of crisis: The influence of the external context and perceived financial threat
Purpose
This study aims to analyse how people's perceived employability was affected during the coronavirus disease 2019 (COVID-19) pandemic. This study explores individuals' perceived financial threat, age and work situation as factors that shape perceived employability.
Design/methodology/approach
Data were collected via a survey at three different times between October 2020 and May 2021, which were chosen to reflect the evolution of the pandemic. The participants (n = 124) reported participants' perceived employability and financial threat during the pandemic in Portugal. Perceived employability is a multidimensional concept, as this includes the following scales: employment protective behaviour, employment risk, job-seeking behaviour, self-control and self-learning.
Findings
Participants' overall perceived employability failed to record significant variance over the period under analysis. Nevertheless, perceived employment protective behaviour decreased the most, especially in the case of young adults (aged 18 to 24). Individuals' perceived financial threat varied according to the external context, being lower during the last moment of data collection, which corresponded to the less-socially and economically restrictive period. Employees with the most stable work condition, i.e. with a permanent employment contract, were those who felt less financially threatened when compared to other respondents. A negative relationship between perceived employability and perceived financial threat was identified during the third moment of data collection.
Originality/value
The research informs about how individuals perceive themselves in a highly unpredictable and unstable context. The longitudinal approach shows how the external context affected people's perceived employability and financial threat throughout the pandemic.UIDB/04928/202
Le succès d’édition des oeuvres de Benito Pérez Galdós: essai de bibliométrie (I)
Este estudo explora, através da comparação entre um lÃder feminino e um masculino, o efeito das práticas de liderança feminina na implicação organizacional, tendo em conta a crescente presença das mulheres, tidas como inclusivas, em lugares de chefia das organizações. O estudo é de carácter correlacional, na medida em que se analisou a associação entre as práticas de liderança, medidas através do LBDQ, e a implicação organizacional, medida com o OCQ. Os questionários foram aplicados a 52 trabalhadores (47 do sexo feminino e 5 do masculino) de uma escola em Lisboa. Não foram verificadas diferenças significativas na implicação organizacional dos participantes que responderam mais favoravelmente ao lÃder feminino e dos que responderam mais favoravelmente ao lÃder masculino
Implementing a maintenance strategic plan using TPM methodology
The market globalization and worldwide competition has raised the level of demand in the industrial sector. Due to this aggressive competitiveness, some management strategies and tools needed to start to be applied in the industry. For example, maintenance has become increasingly important in the production planning and strategy of some companies. This work focuses on the implementation of a strategic maintenance plan, applied in an industrial context, namely in a company of Clutches and Hydraulic Controls. The Total Productive Maintenance (TPM) methodology application was worked on and implemented at two sections, CNC Lathes and CNC Machining Centers, to focus on eliminating losses due to inefficiencies. In this way, the main problems detected in relation to the cells were eliminated. New autonomous maintenance procedures (AM) and preventive maintenance plans with well-defined schedule were also developed. The results obtained were very positive: there was a decrease of 23% in breakdowns in CNC lathes sector and 38% in CNC machining centers sector. In global terms, there was an increase in the availability of the machines and the Overall Equipment Effectiveness (OEE) of approximately 5%. The implementation procedure and the compromise adopted by the whole company staff and management was the secret to success.info:eu-repo/semantics/publishedVersio
As Diferenças Culturais e Socioeconômicas e o Impacto na Internacionalização Empresarial: Um Estudo Comparativo entre duas Empresas Multinacionais
Expatriation has emerged as an important issue in managerial studies. This study aims to analyze the influence of socioeconomic and cultural factors in the expatriation management and the internationalization of two companies from culturally close countries. Therefore, a qualitative study of multiple cases was carried out in a Brazilian and Portuguese multinational. Through a semi-structured script, 30 interviews were performed, which were analyzed by the content analysis technique with the assistance of Max-Qda software (2007) in the organization of analysis categories. The reports of the Portuguese and Brazilians are very similar when they discuss the differences between the two countries. Al though they are close in relation to their history, the understanding difficulty in the use of the Portuguese language, the differences in decision-making and the still existing prejudices, mark the interaction between professionals and companies, revealing proximity and distance. However, the main highlighted aspects that influence the expatriation and internationalization of the analyzed companies are the labor legislation for expatriates, bureaucracy, corruption, ‘Brazilian way’, the difference of infrastructure and basic education
Cultural and socioeconomic differences and the impact on entrepreneurial internationalization : a comparative study between two multinational companies
A expatriação tem emergido como uma temática importante nos estudos gerenciais. O presente estudo tem por objetivo analisar os fatores culturais e socioeconômicos que impactam no processo de expatriação e internacionalização de duas empresas de paÃses próximos culturalmente. Para tanto, foi realizado um estudo qualitativo de múltiplos casos em uma multinacional brasileira e uma portuguesa. Por meio de um roteiro semiestruturado, foram realizadas 30 entrevistas, as quais foram analisadas pela técnica de análise de conteúdo com o auxÃlio do software Max-Qda (2007) na organização das categorias de análise. Os relatos dos portugueses e dos brasileiros são muito similares quando abordam as diferenças entre os dois paÃses. Embora próximos em função de sua história, a dificuldade com os entendimentos no uso da lÃngua portuguesa, as diferenças na tomada de decisões, os preconceitos ainda existentes marcam a interação entre os profissionais e as empresas, revelando-se, assim, proximidades e distanciamentos. São citadas ainda a legislação para os expatriados, burocracia, corrupção, ‘jeitinho brasileiro’, a diferença de infraestrutura e da educação básica como entraves.Expatriation has emerged as an important issue in managerial studies.

Predição da densidade básica de Eucalyptus sp. por meio da técnica não destrutiva de ultrassom
This work aimed to estimate the basic density of Eucalyptus sp. wood, using the non-destructive ultrasound technique. For this, 113 specimens with nominal dimensions of 2.5 x 2.5 x 57.5 cm (tangential x radial x longitudinal) were used, being in equilibrium humidity. To perform the density estimation, the three-dimensional model that governs the propagation of longitudinal waves in isotropic solids was used. The input variables of the model were determined, being the longitudinal modulus of elasticity by static bending, the Poisson's ratio by numerical methods and the propagation velocity of the ultrasound wave by a non-destructive ultrasound testing equipment. The basic density was also obtained by the hydrostatic balance method as a reference value. The actual average basic density was 595.40 kg.m-3 and the estimated one was 591.21 kg.m-3. The estimated value had a strong correlation with the observed value with r =0.89. The estimation by the three-dimensional model showed a low error with an RMSE of 6.50% and a bias of 0.59%. The estimation of the basic density using this method obtained good precision, being similar to the resistography technique.Este trabalho teve o objetivo de estimar a densidade básica da madeira de Eucalyptus sp., por meio da técnica não destrutiva de ultrassom. Para tal foram usados 113 corpos de provas com dimensões nominais de 2,5 x 2,5 x 57,5 cm (tangencial x radial x longitudinal), estando na umidade de equilÃbrio. Para realizar a estimação da densidade, foi usado o modelo tridimensional que rege a propagação de ondas longitudinais em sólidos isotrópicos. Foram determinadas as variáveis de entrada do modelo, sendo o módulo de elasticidade longitudinal por flexão estática, o coeficiente de Poisson por métodos numéricos e a velocidade de propagação da onda de ultrassom por um equipamento de ensaios não destrutivos de ultrassom. Também foi obtida a densidade básica pelo método da balança hidrostática como valor de referência. A densidade básica média real foi de 595,40 kg.m-3 e a estimada de 591,21 kg.m-3. O valor estimado teve forte correlação com o valor observado com r = 0,89. A estimação pelo modelo tridimensional apresentou baixo erro com RMSE de 6,50% e viés de 0,59%. A estimação da densidade básica empregando este método obteve boa precisão, sendo semelhante à técnica de resistografia
Search for the standard model Higgs boson produced in association with top quarks and decaying into a pair in collisions at = 13  TeV with the ATLAS detector
A search for the standard model Higgs boson produced in association with a top-quark pair, tt¯H, is presented. The analysis uses 36.1  fb-1 of pp collision data at s=13  TeV collected with the ATLAS detector at the Large Hadron Collider in 2015 and 2016. The search targets the H→bb¯ decay mode. The selected events contain either one or two electrons or muons from the top-quark decays, and are then categorized according to the number of jets and how likely these are to contain b-hadrons. Multivariate techniques are used to discriminate between signal and background events, the latter being dominated by tt¯+jets production. For a Higgs boson mass of 125 GeV, the ratio of the measured tt¯H signal cross-section to the standard model expectation is found to be μ=0.84-0.61+0.64. A value of μ greater than 2.0 is excluded at 95% confidence level (C.L.) while the expected upper limit is μ<1.2 in the absence of a tt¯H signal.Peer Reviewe
Performance of the ATLAS Track Reconstruction Algorithms in Dense Environments in LHC Run 2
With the increase in energy of the Large Hadron Collider to a centre-of-mass energy of 13 for Run 2, events with dense environments, such as in the cores of high-energy jets, became a focus for new physics searches as well as measurements of the Standard Model. These environments are characterized by charged-particle separations of the order of the tracking detectors sensor granularity. Basic track quantities are compared between 3.2 fb of data collected by the ATLAS experiment and simulation of proton–proton collisions producing high-transverse-momentum jets at a centre-of-mass energy of 13 . The impact of charged-particle separations and multiplicities on the track reconstruction performance is discussed. The track reconstruction efficiency in the cores of jets with transverse momenta between 200 and 1600 is quantified using a novel, data-driven, method. The method uses the energy loss, , to identify pixel clusters originating from two charged particles. Of the charged particles creating these clusters, the measured fraction that fail to be reconstructed is and for jet transverse momenta of 200–400 and 1400–1600 , respectively.Peer Reviewe
Measurements of differential cross-sections of highly boosted top quarks decaying to all-hadronic final states in collisions at TeV using the ATLAS detector
Measurements are made of differential cross-sections of highly boosted pair-produced top quarks as a function of top-quark and tt¯ system kinematic observables using proton-proton collisions at a center-of-mass energy of s=13  TeV. The data set corresponds to an integrated luminosity of 36.1  fb-1, recorded in 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. Events with two large-radius jets in the final state, one with transverse momentum pT>500  GeV and a second with pT>350  GeV, are used for the measurement. The top-quark candidates are separated from the multijet background using jet substructure information and association with a b-tagged jet. The measured spectra are corrected for detector effects to a particle-level fiducial phase space and a parton-level limited phase space, and are compared to several Monte Carlo simulations by means of calculated χ2 values. The cross-section for tt¯ production in the fiducial phase-space region is 292±7(stat)±71(syst)  fb, to be compared to the theoretical prediction of 384±36  fb.Peer Reviewe
Measurement of charged-particle distributions sensitive to the underlying event in TeV proton-proton collisions with the ATLAS detector at the LHC
We present charged-particle distributions sensitive to the underlying event, measured by the ATLAS detector in proton-proton collisions at a centre-of-mass energy of 13 TeV, in low-luminosity Large Hadron Collider fills corresponding to an integrated luminosity of 1.6 nb. The distributions were constructed using charged particles with absolute pseudorapidity less than 2.5 and with transverse momentum greater than 500 MeV, in events with at least one such charged particle with transverse momentum above 1 GeV. These distributions characterise the angular distribution of energy and particle flows with respect to the charged particle with highest transverse momentum, as a function of both that momentum and of charged-particle multiplicity. The results have been corrected for detector effects and are compared to the predictions of various Monte Carlo event generators, experimentally establishing the level of underlying-event activity at LHC Run 2 energies and providing inputs for the development of event generator modelling. The current models in use for UE modelling typically describe this data to 5% accuracy, compared with data uncertainties of less than 1%.Peer Reviewe
