- Emotional Intelligence Assessment, Interpersonal Communication and Integration of People With Disabilities in the Portuguese Labour MarketPublication . Nogueira, Marta; Sousa, Célia; Cuadrado-Gordillo, IsabelThis research aims to evaluate emotional intelligence, interpersonal communication and the integration of PwD's in the labor market. In this sense, and given the difficulties experienced by these people during the process of labor inclusion, we have tried to: explore and understand the emotions felt by these workers during their working hours and how they manage them; how communication is processed in this context; and also to verify to what extent the Convention on the Rights of Persons with Disabilities has improved the process of inclusion. The mixed methodology was used, using qualitative and quantitative research. Fifty workers with disabilities and 314 work colleagues of the Auchan Portugal Group participated in the study. The results showed that the PwD's recognize their emotions when interacting with co-workers, however most disguise them when they feel discomfort, ending up not having a clear communication at the organizational level. Moreover, it was found that, although most PwD's feel integrated, it suggests a greater sensitivity of the employer, adapted work and more accessibility in the workplace.
- Adaptive Deep Learning-Based Point Cloud Geometry CodingPublication . Andre F. R. Guarda; Rodrigues, Nuno M. M.; Fernando PereiraPoint clouds are a very rich 3D visual representation model, which has become increasingly appealing for multimedia applications with immersion, interaction and realism requirements. Due to different acquisition and creation conditions as well as target applications, point clouds’ characteristics may be very diverse, notably on their density. While geographical information systems or autonomous driving applications may use rather sparse point clouds, cultural heritage or virtual reality applications typically use denser point clouds to more accurately represent objects and people. Naturally, to offer immersion and realism, point clouds need a rather large number of points, thus asking for the development of efficient coding solutions. The use of deep learning models for coding purposes has recently gained relevance, with latest developments in image coding achieving state-of-the-art performance, thus making natural the adoption of this technology also for point cloud coding. This paper presents a novel deep learning-based solution for point cloud geometry coding which is able to efficiently adapt to the content’s characteristics. The proposed coding solution divides the point cloud into 3D blocks and selects the most suitable available deep learning coding model to code each block, thus maximizing the compression performance. In comparison to the state-of-the-art MPEG G-PCC Trisoup standard, the proposed coding solution offers average quality gains up to 4.9dB and 5.7dB for PSNR D1 and PSNR D2, respectively.
- Relationship between body image and motivation in dancersPublication . Faria, Beatriz; Frontini, Roberta; Antunes, RaulConsidering the importance of understanding how dancers perceive their body image, it is important to analyse the relationships that are established with other factors, namely with the way dancers regulate their behaviour. Therefore, the purpose of this work was to analyse the relationship between the way dancers regulate their behaviour and their satisfaction with body image, including a comparison between adolescents and adults.
- Emotional Intelligence, Interpersonal Communication and Integration of People With Disabilities Inserted in the Labor MarketPublication . Nogueira, Marta; Sousa, Célia; Cuadrado-Gordillo, IsabelThe main objective of this doctoral research is to understand how the labour market integrates the people with disabilities (PwD's), to understand what emotions they feel and how they generate them throughout the working day, and also to know how communication is processed in the workplace. In this study, the mixed methodology was chosen, using qualitative and quantitative research. In the qualitative methodology, the semi-structured interview was used and in the quantitative methodology, the questionnaire was used. The sample consisted of 50 workers with disabilities and 314co-workers of the same(n=314), employees of the Auchan Portugal Group. Through the results obtained, the PwD's recognize their emotions when interacting with their co-workers, however, most disguise the discomfort felt, not communicating clearly what emotions they felt. Most disabled workers have a high degree of awareness of the emotions experienced in the workplace but are reluctant to communicate these emotions to co-workers. This prevents colleagues from understanding what PwD is feeling and is an obstacle to clear communication.
- Have Fintech companies higher values than their traditional financial peers?Publication . Vila, Yoandy Santana; Jorge, Maria João da Silva; Duarte, Elisabete Fernanda MendesThe main objective of this paper is to prove that fintech companies have more value than traditional financial companies. To achieve that, we selected a sample of 13 fintech firms from the KBW Nasdaq Financial Technology Index plus 93 firms from the NASDAQ Financial-100 Index, all of them listed on the NASDAQ Composite Index. We created three portfolios: fintech firms (13); traditional financial firms (93) and the full market portfolio (106). Using the three-factor model of Fama and French, we compared the weekly returns of the fintech portfolio with the two others as benchmarks. Our empirical results showed statistically significant evidence that the fintech portfolio outperform both benchmarks portfolios, and so we can prove our hypothesis that the fintech companies create more value than traditional financial companies.
- Green Supply Chain Management: a case study of Brazilian cosmetic firmsPublication . Araújo, Adélia Cristina Evangelista Silva de; Simões, Paula Marisa NunesThe increasing environmental concern can be seen as a challenge and a strategic issue for firms nowadays. Within this context, green supply chain management (GSCM) can provide a solution to this problem, as it is a way to achieve competitive advantage while enhancing the environmental sustainability. This dissertation attempts to bridge a gap in GSCM theory by analysing it in the context of the cosmetic sector in a developing country from South America. By doing so, we intend to analyse GSCM in Brazilian cosmetic sector. The aim of this dissertation is threefold: to examine the pressures for the adoption of green practices in SC in Brazil, to estimate the effect on its operation and to understand the way the central firm induces GSCM practices on its suppliers. Thus, three research questions (RQ) guide the study: RQ1: What are the main institutional pressures that have influenced the adoption of GSCM practices in Brazilian cosmetic firms?; RQ2: What is the effect (economic and environmental) of GSCM practices implementation for the cosmetic firm?; RQ3: In what ways does the central firm act to induce sustainable procedures in its supply chain (SC)? A multiple case study was conducted with two Brazilian cosmetic firms, AymaraUna and Bio Extratus. The results indicate: (1) internal guidelines as major drivers in GSCM adoption; (2) positive relation between the adoption of green practices and performance (both environmental and economic), only in the case of Bio Extratus; and (3) it was not possible to determine the extension of influence the focal firms might have in GSCM adoption by its suppliers. To our knowledge, this is the first multiple case study relating GSCM from Brazilian cosmetic firms.

- Os efeitos da Performance Financeira no Investimento em Indústria 4.0Publication . Harbuzyuk, Eduard; Ferreira, Vítor Hugo SantosA nova revolução industrial é das mais desafiantes e diversificadas. Esta criou, e transformou, o nosso mundo nas mais diferentes áreas, como na indústria, biologia, medicina, biotecnologia, armazenamento de energia, computação quântica e, até mesmo, na nossa estrutura societária. A Quarta Revolução Industrial é diferente das suas antepassadas, pela sua velocidade e amplitude, por isso, é que todos os dias vemos algo novo e inovador. A disrupção também foi um fator diferenciador nesta revolução, que permitiu a comunicação entre vários aparelhos eletrónicos, na qual ocorre a transferência de dados autonomamente. As entidades, e até mesmo os países, estão numa corrida de inovação todos os anos. As empresas portuguesas investem milhões de euros em produtos e processos inovadores para fazer face às suas necessidades, baixar os seus gastos e aumentar as suas competências face à concorrência. Existem várias áreas nas quais as empresas investem o seu capital, como por exemplo: Internet of Things (IoT) (Internet das Coisas), Robótica, Inteligência Artificial (IA) e Impressão 3D. A dúvida que surge a questão que iremos responder na nossa investigação, é se a performance financeira histórica tem alguma importância na decisão de investimento em ativos de Quarta Revolução Industrial, ou seja, se o efeito da performance financeira histórica da empresa tem algum grau de associação com a decisão de investimento em Indústria 4.0. Nesta investigação, de forma a conseguir analisar a correlação entre a Performance Financeira e o Investimento em Tecnologia de Quarta Revolução Industrial, efetuamos, em primeiro lugar, uma recolha de dados primários, através da realização de um questionário a 66 empresas portuguesas. Com base na listagem de empresas inquiridas, procedemos à recolha dos dados secundários, através da plataforma de dados da Sabi. Para analisar a correlação entre os dados, recorremos ao software de análise estatística SPSS, através de uma análise do Coeficiente de Correlação de Spearman. Este método estatístico mede a intensidade da relação entre variáveis ordinais, variáveis onde existe ordenação entre categorias, no nosso caso, a medição de relação entre o indicador financeiro e o valor de investimento que é representada por uma variável categórica que indica o intervalo de investimento selecionado pela empresa inquirida. Os resultados obtidos demonstram que existe uma relação entre a antiguidade e alguns dos indicadores de performance financeira de rentabilidade e dimensão, com os investimentos em ativos de Quarta Revolução Industrial.

- Contrato de serviço doméstico – Reflexão sobre o filho menor dos contratos especiaisPublication . Nogueira, Filipa Alexandra Lopes; Costa, Ana Isabel Lambelho; Gonçalves, Luísa AndiasO presente trabalho concretiza o estudo de alguns dos direitos dos trabalhadores do serviço doméstico, dado que é um trabalho quase invisível e tão importante na nossa sociedade. Ao longo dos anos, temos assistido a constantes transformações político jurídicas do Direito do Trabalho. No entanto, constatamos que o contrato de serviço doméstico, não tem sido objeto dessas modificações e continua imutável desde 1992, fruto do contexto, salvo entendimento contrário das condições particularmente especificas em que a relação de trabalho se desenrola. Contudo, a lei que disciplina o regime especial do contrato de trabalho de serviço vê-se subordinada à disciplina do regime geral sempre que a matéria não seja nele tratada. E daqui nascem alguns problemas pois nem todos os institutos jurídicos se coadunam com o carácter especial desta relação de trabalho. Este é o ponto de partida para a abordagem de algumas matérias, como o âmbito e a forma do contrato, a retribuição, a extinção da relação de trabalho, refletindo sobre o que é ou não compatível com a especificidade da relação de trabalho de carácter especial do serviço doméstico.
