Workshops Proceedings

The idea behind the Workshops Proceedings document is to collect in an eBook the information of all the Nanouptake Working Group (WG) Workshops before April 2019 where the participants have been presenting their last research work in nanofluids

A comparative analysis of metal subgenres in terms of lexical richness and keyness

Metal music is realized under a vast variety of subgenres all of which have their unique (or shared) characteristics not only in sound but also in their lyrics. Much research has been done to distinguish or classify subgenres but little has addressed the linguistic differences across them. This study seeks to find out the lexical richness and keyness levels of heavy metal, thrash metal and death metal using a corpus of 200 songs from each subgenre with a total of 600 songs. The selection of the bands and songs was carried out finding references in the metal literature. The metal literature in the present study takes into account the academic books and articles on metal as well as noteworthy media productions, websites and metal blogs such as Metal Evolution and Encyclopaedia Metallum. The song lyrics were manually processed and meta-data, mark-ups and repeats have been removed so that the differences in repeat lengths do not affect the comparisons. Furthermore, the analyses used in the study are sensitive to repeats as they measure the frequencies and repeat ratios of the words. The song lengths – after the processing – were limited to lower and upper thresholds of 100 and 400 words. The songs were analyzed for their lexical richness levels in three aspects: 1) lexical variation, 2) lexical sophistication and 3) lexical density. Lexical variation was operationalized as TTR, Guiraud, Uber and HD-D. Lexical sophistication was measured using lexical frequency profile with two different frequency lists – the GSL and the BNC/COCA – by looking at the ratios of tokens and types which fell beyond the most frequent two thousand words (Laufer 1995). Another sophistication measure – P_Lex – which also runs on GSL, was applied. Lexical density analysis was based on the ratio of content words to all tokens in the texts. In order to complement this quantitative and data-driven approach, a keyness analysis was administered to add a qualitative dimension to the research. All lexical richness analyses pointed out to statistically significant differences between all subgenres, marking heavy metal as the least and death metal as the most lexically rich one. Keyness analysis indicated differences among all three subgenres as well. Heavy metal key words tended to be Dionysian whereas thrash and death metal keywords were more Chaotic as proposed by Weinstein (2000). Finally, a correlation analysis showed that all lexical richness measures were statistically significantly correlated to each other. Based on the findings, it could be claimed that 1) these three subgenres differ from each other not only in terms of music but also of lexical richness levels and key words and 2) lexical richness analyses, coupled with keyness, are capable of reflecting the genre differences in song lyrics. However, as a result of a discriminant analysis of the present corpus, a reverse approach whereby genres are attempted to be classified based on lexical features does not provide a pattern which fully corresponds to the existing classifications

Organisational maturity and information systems and technology projects in healthcare: the mediation of project management.

Doutoramento em GestãoThe challenges that health organisations face today is to get better organisational performance, reliable information, faster quality services at prices that should be affordable to the entire population. To fulfil this important goal, health organisations require more comprehensive and integrated approaches such as, but not limited to, optimise their available resources, eliminate inefficiencies and achieve the planned benefits from investments in Information Systems and Technology (IS/IT). Healthcare organisations must improve their management practices and internal procedures to answer the increasing demand of managers, health professionals and the public in general, for more and better information. Health organisations adopt a patient-centred care approach and invest massively in IS/IT, hoping that these investments will improve medical care and patient needs. The main objective of our research is to analyse how the Organisational Maturity affect IS/IT Project Success in Healthcare and if that success is enhanced by using Project Management practices. There is evidence that there is a direct relationship between these variables and that Project Management practices can mediate it, helping to increase the effectiveness of IS/IT projects. Furthermore, the application of the Project Management practices can also improve confidence that the results of these investments meet stakeholders’ expectations, both by the benefits accomplishment and by adding a perceived value to organisations. This study develops and validates an instrument to analyse the data collected from a survey to professionals’ perceptions about the IS/IT Project Success in Healthcare organisations. The results confirm that Project Management has a mediating effect on the relationship between Organizational Maturity and success of IS/IT projects and higher levels of Organisational Maturity will generate more successfully IS/IT projects, although the presence of the mediator Project Management can, in specific situations, affect negatively the correlation between Organisational Maturity and IS/IT Project Success.Os desafios que enfrentam atualmente as organizações de saúde estão diretamente relacionados com o fato de ambicionarem um melhor desempenho, mais e melhor informação de saúde, serviços de qualidade mais céleres. a custos acesíveis à maioria da população. Para o total cumprimento deste desiderato as organizações de saúde têm investido em soluções tecnológicas mais abrangentes e integradas de forma a otimizar os recursos disponíveis, eliminar ineficiências e atingir os benefícios plenos dos investimentos em Sistemas e Tecnologias da Informação (SI/TI). As organizações de saúde procuram melhorar as suas práticas de gestão para dar resposta a uma crescente procura de informação de saúde por parte de gestores, profissionais e público em geral. As organizações de saúde adotaram uma abordagem centrada no paciente e realizaram significativos investimentos em SI/TI na expetativa de que estes trouxessem melhorias ao nível assistencial e na satisfação das expetativas dos seus utilizadores. O principal objetivo deste trabalho é analisar como a Maturidade Organizacional afeta o sucesso do projeto em SI/TI em saúde e se esse sucesso é potenciado pela utilização de práticas de gestão de projetos. Há evidências da existência de uma relação direta entre esstas duas variáveis e que as práticas de Gestão de Projetos a podem mediar, ajudando a aumentar a eficácia dos projetos de SI/TI. Além disso, a aplicação das práticas de Gestão de Projetos podem melhorar a confiança nos resultados dos investimentos e atender às expectativas das diferentes partes interessadas, tanto pela realização de benefícios quanto pela criação de valor percebido para as organizações. Este estudo analisa os dados recolhidos de um questionário à perceção dos profissionais sobre o sucesso dos projetos IS/IT nas organizações de saúde. Os resultados obtidos confirmam. Os resultados confirmam que o Gestão de Projetos tem um efeito mediador na relação entre Maturidade Organizacional e Sucesso de Projetos de SI/TI e níveis mais elevados de Maturidade Organizacional gerarão projetos SI/TI mais bem-sucedidos, embora a presença do mediador Gestão de Projetos, possa, em circunstâncias específicas situações, afetar negativamente a correlação entre as duas variáveis.N/
