Artistic Emigration From Portugal To Paris In The First Half Of The 1960s: Six Portuguese Painters From Paris Revisited

This paper proposes to revisit some issues related to the impact of emigration on the paths followed by a group of six Portuguese painters who settled in Paris between 1958 and 1961. To do that, it will analyze and contextualize the evolution of their work in the first half of the 1960’s, and it will recall the small exhibition Seis Pintores Portugueses de Paris that opened in 1966 in Lisbon with the purpose of highlight the particularities of the artistic research that was being developed by those artists in Paris, integrating them into the international artistic movements of the period

Performance evaluation in Irish racehorses with dorsal displacement of the soft palate following the laryngeal tie-forward procedure

Dissertação de Mestrado Integrado em Medicina VeterináriaThe horse races are a very important money income in Ireland, being required that the racehorses show the full potential at the races. The dorsal displacement of the soft palate (DDSP) is a common cause of poor performance and exercise intolerance in racehorses being the laryngeal tie-forward procedure the surgical technique with the highest success rate on the correction of this condition. A performance evaluation study was performed to evaluate the significance of the laryngeal tie-forward procedure for correction of DDSP in racehorses. The race performance data was collected for the horses (n = 16) and the effect of surgery on racing performance, the effect of recovery time in earnings and the difference of the earnings by sex and age were analyzed. The racing performance improves after surgery (P = 0,0138), with an increase in the earnings three times the baseline value four races after surgery. The laryngeal tie-forward procedure corrects DDSP, increasing the race performance above the baseline value.RESUMO - Avaliação da performance desportiva em cavalos de corrida irlandeses com deslocamento dorsal do palato mole após a realização de cirurgia para movimento rostral da laringe - As corridas de cavalos são uma grande fonte de riqueza na Irlanda, sendo importante que os cavalos de corrida apresentem o potencial máximo durante as corridas. O deslocamento dorsal do palato (DDP) é uma causa comum de diminuição da performance e de intolerância ao exercício em cavalos de corrida, sendo a cirurgia para movimento rostral da laringe a técnica cirúrgica com maior taxa de sucesso no tratamento desta condição. Foi realizado um estudo para avaliar a significância da cirurgia para movimento rostral da laringe para correção de DDP na performance desportiva. Os dados da performance desportiva foram recolhidos para todos os cavalos (n = 16) e foi analisado o efeito da cirurgia na performance desportiva, o efeito do tempo de recuperação nos ganhos monetários e a diferença dos ganhos monetários por género e idade. A performance desportiva melhora após a cirurgia (P = 0,0138), aumentando os ganhos monetários três vezes o valor base, quatro corridas após a cirurgia. A cirurgia para movimento rostral da laringe corrige o DDP, aumentando a performance desportiva para valores superiores ao valor base

Beyond skill mismatch. Why there are so many unfilled vacancies and simultaneously high unemployment rates?

The traditional analysis of unfilled vacancies is grounded primarily in the interpretationof the Beveridge curve and mainly in the explanation of skills mismatch. However,it is easily verified that this is insufficient. In this text we try to collect, based on theavailable literature, a number of variables that can consolidate the comprehension ofthis phenomenon. We try to build a model that discriminates these explanatory variables(administrative issues, vacancy features, labour market and job seeker characteristics)in order to provide users and decision makers a set of decision-making aids,based on evidence criteria, to set reliable employment and training policies and not onpolitical-ideological fluctuations

FUNDOS PÚBLICOS E CRIAÇÃO DE AUTO-EMPREGO

When countries are in times of limited financial resources the provision of public funds to active labour market policies should receive close attention from the governments and become as effective as possible. This aim should be always grounded in evidence criteria and not in political insights or ideological social constructions.This paper aims to provide some data and potential conclusions in order to deliver a modest contribution to the evidence-based debate on ALMP policy making in Portugal.The analysis was made over two variables: the public expenditure on self-employment creation measures and the number of self-employment positions created. The results suggest that there is a weak linear correlation between the two variables. This might point to an inefficiency in the use of public funds; or in other hand, it may mean that public expenditure is only remotely responsible for the creation of self-employment positions and, therefore, that there are other variables (or reasons) that explain the phenomenon.Quando os países experimentam tempos de escassez de recursos financeiros a alocação de fundos públicos destinados a políticas ativas de emprego, deve merecer uma atenção incisiva pelos governos e tornar-se o mais eficiente possível. Este objetivo deve ser sempre alicerçado em critérios de evidência e não em instintos políticos ou construções sociais ideológicas. Pretende-se com este texto, obter alguns dados e potenciais conclusões, de modo a podermos oferecer uma modesta contribuição para o debate baseado em evidências sobre a construção de políticas ativas de emprego, em Portugal. A análise incidiu sobre duas variáveis: a despesa pública em medidas ativas de criação do próprio emprego, ou empresa, e o número efetivo de empregos assim criados. Os resultados sugerem que existe uma correlação linear fraca entre estas duas variáveis. Tal pode eventualmente indicar uma ineficiência na utilização dos fundos públicos. Ou, por outro lado, pode significar que a despesa pública é apenas remotamente responsável pela criação do próprio emprego e que, portanto, existem outras variáveis (ou razões) que explicam o fenómeno

(REVISITING) ALLOMORPHISMS IN CORPORATIONS AND HRM IN INFORMATIONAL SOCIETY

The informational society is not innocuous for corporations and organizations. The assortment of allomorphic phenomenon that are taking place in corporations and on the implicit human resources management (i.e. persons) cannot set aside any indifference among entrepreneurs, workers or social partners. The corporation’s frameworks, the structure and performance, the person’s management, the labour relations and other new dimensions are analyzed on the present paper, trying to preview some tendencies.We make an attempt to shape the behaviors and forthcoming procedures of the social actors in order to forecast the management and the labour, with the certainty that the uncertainty is part of the future.Key-words: informational society; allomorphisms; changing; trends; organizations; corporations; globalizatio

Aprendizagem automática aplicada à deteção de pessoas baseada em radar

The present dissertation describes the development and implementation of a radar-based system with the purpose of being able to detect people amidst other objects that are moving in an indoor scenario. The detection methods implemented exploit radar data that is processed by a system that includes the data acquisition, the pre-processing of the data, the feature extraction, and the application of these data to machine learning models specifically designed to attain the objective of target classification. Beyond the basic theoretical research necessary for its sucessful development, the work contamplates an important component of software development and experimental tests. Among others, the following topics were covered in this dissertation: the study of radar working principles and hardware; radar signal processing; techniques of clutter removal, feature exctraction, and data clustering applied to radar signals; implementation and hyperparameter tuning of machine learning classification systems; study of multi-target detection and tracking methods. The people detection application was tested in different indoor scenarios that include a static radar and a radar dynamically deployed by a mobile robot. This application can be executed in real time and perform multiple target detection and classification using basic clustering and tracking algorithms. A study of the effects of the detection of multiple targets in the performance of the application, as well as an assessment of the efficiency of the different classification methods is presented. The envisaged applications of the proposed detection system include intrusion detection in indoor environments and acquisition of anonymized data for people tracking and counting in public spaces such as hospitals and schools.A presente dissertação descreve o desenvolvimento e implementação de um sistema baseado em radar que tem como objetivo detetar e distinguir pessoas de outros objetos que se movem num ambiente interior.

Production of recombinant protein hLIF in static and dynamic systems of animal cell culture

Thesis for the Degree of Master of Science in Biotechnology Universidade Nova de Lisboa, Faculdade de Ciências e TecnologiaThe present work focuses the optimization of the production of human Leukemia Inhibitory Factor (hLIF) by human embryonic kidney 293 (HEK293) - EBNA1 cell line cultured as suspension aggregates in spinner flask. The effects of initial cell density and feeding-regime in cellular growth and productivity were evaluated. A first phase occurs until the end of exponential growth in medium containing serum, being followed by puromycin selection of cells containing hLIF plasmid. A second phase, the production phase, is developed under serum-free conditions. Three initial cell densities (2´104 cells.mL-1, 2´105 cells.mL-1 and 2´106 cells.mL-1) were tested and the effect on maximum cell density and cell aggregate size distribution was evaluated. The inoculum of 2´105 cells.mL-1 led to final higher cellular densities around 7´106 cells.mL-1 and homogeneous aggregates around 278 μm were observed. The effect of the feeding-regime was then studied for the production of recombinant hLIF with an initial cell density of 2´105 cells.mL-1 by performing metabolite analysis Metabolite analysis revealed the occurrence of glucose and glutamine starvation upon 9 and 7 days, respectively, in 25% FR. Therefore, glutamine acted as an alternative carbon, energy and aminoacid source in HEK293-EBNA1 growth. Observed lactate levels were bellow the inhibition limit concentrations (30 mM 1).HEK293-EBNA1 did not seem to be affected by the produced levels of ammonia. In conclusion, the 25% feeding regime at 2´105 cells.mL-1 initial cell density lead to the higher viable cell densities, either along culture time at growth and at production phase, with aggregates in suspension below necrotic diameters. This experiment conditions also allowed achieving the higher LIF volumetric productivity, 125 ± 2.2 ng.mL-1
