A importância dos média e da língua de acolhimento na integração de imigrantes. Estudos de caso : a comunidade nepalesa de Portugal e a comunidade portuguesa em Macau

Esta pesquisa foca-se na comunidade imigrante portuguesa em Macau e na comunidade imigrante nepalesa em Portugal. Analisa os usos dos média – étnicos, mainstream e transnacionais - por imigrantes durante o processo de integração: na manutenção de laços com o país de origem e na adaptação à sociedade de acolhimento, em que a língua de acolhimento assume um papel crucial. A investigação enquadra-se nos estudos de audiências e baseia-se na teoria dos Usos e Gratificações dos Média (Katz, Blumler, & Gurevitch, 1974). No que respeita à integração assenta no modelo de estratégias de aculturação de Berry & Sam (2001, 2006). Quanto à língua, assenta na teoria do poder e da prática de Bourdieu (1991), especificamente na parte relativa ao poder simbólico da língua. Quanto à metodologia, foram realizadas oito entrevistas em profundidade na comunidade nepalesa e 29 entrevistas na comunidade portuguesa. A amostra foi de conveniência e teoricamente sustentada. A seguir às entrevistas, foi feita uma análise de conteúdo individual e transversal. Esta tese pretende contribuir para o enriquecimento de linhas de investigação sobre audiências activas dos média. Poderá servir de fonte de informação para políticas relacionadas com a integração de imigrantes, nomeadamente, para reformulação de políticas relacionadas com os média e com a língua de acolhimento. No caso de empresas de comunicação, a informação obtida poderá ser útil para adaptarem melhor os seus conteúdos a este público específico.

Crowdfunding

Crowdfunding, as we know it today, is a very recent activity that was born almost accidentally in the end of the 90’s decade. Due to the advent of the internet and the social networks, entrepreneurs are now able to promote their projects to a very large community. Whether it is composed by family, friends, acquaintances or simply people that are interested in the same topic or share the passion, the community is able to fund new ventures by individually investing modest amounts of money. In return, the entrepreneur can offer symbolic rewards, shares or other financial returns. New crowdfunding platforms are born almost every day all over the world, offering a new way of raising capital for their projects or a new way to invest their money in innovative ventures. Although crowdfunding is still finding its place in the financial services, successful cases such as Kickstarter demonstrate the power of the crowd in boosting creativity and productivity, financing thousands of projects by raising millions of dollars from thousands of investors. Due to regulatory restrictions, the most prominent model for now is reward-based crowdfunding, where the investors are prized with symbolic returns or privileged access to the products or services offered by the entrepreneurs. Other models such as peer-to-peer lending are also surging, allowing borrowers access to capital at a lower cost compared to so-called traditional financial institutions, and offering lenders a higher rate of return. But when it comes to offering shares to investors, i.e. using equity-based crowdfunding, entrepreneurs face regulatory obstacles in almost every country, where legislation was passed decades ago with the objective of promoting financially-capable ventures and protecting investors. Access to capital has become more difficult after the global economic recession of 2008, and for most countries it will not get easier in the near future, leaving start-ups and small enterprises with few options to start or expand their operations. In this study we attempt to answer the following research questions: how has equity-based crowdfunding evolved since its creation? Where and how has equity-based crowdfunding been implemented so far? What are the constraints and opportunities for implementing equity-crowdfunding in the world, and more particularly in Portugal? Finally, we will discuss the risks of crowdfunding and reflect on the future of this industry.

Primusinter (ím)pares - análise da presença dos académicos nos plateaux informativos da TV portuguesa

Os académicos estão a tornar-se uma presença cada vez mais visível nos plateaux informativos da TV portuguesa. Não são um grupo muito diversificado. Pelo contrário. Apresentam-se como uma confraria que é oriunda das universidades de Lisboa e pertence a um reduzido número de campos de saberes. Aos plateaux televisivos portugueses dificilmente chegará o fazer-ciência concreto. O que chega são alguns dos seus actores, o que não significa que o consigam por um efeito de reconhecimento inter pares, mas, antes, por um efeito de verdadeiras imparidades: porque já adquiriram suficiente capital simbólico em zonas exteriores ao campo científico. Zonas mais limítrofes, como o campo institucional-académico, ou zonas mais afastadas, como o campo comunicacional.

Automatically estimating iSAX parameters

The Symbolic Aggregate Approximation (iSAX) is widely used in time series data mining. Its popularity arises from the fact that it largely reduces time series size, it is symbolic, allows lower bounding and is space efficient. However, it requires setting two parameters: the symbolic length and alphabet size, which limits the applicability of the technique. The optimal parameter values are highly application dependent. Typically, they are either set to a fixed value or experimentally probed for the best configuration. In this work we propose an approach to automatically estimate iSAX’s parameters. The approach – AutoiSAX – not only discovers the best parameter setting for each time series in the database, but also finds the alphabet size for each iSAX symbol within the same word. It is based on simple and intuitive ideas from time series complexity and statistics. The technique can be smoothly embedded in existing data mining tasks as an efficient sub-routine. We analyze its impact in visualization interpretability, classification accuracy and motif mining. Our contribution aims to make iSAX a more general approach as it evolves towards a parameter-free method.

Gender and media: where do we stand today?

Nowadays, the public discourses about gender equality are commonly accepted in Western society. In fact, we live in an era of “equality illusion” (Banyard, 2010) because the mainstream discourses incorporate gender in the agenda, conveying the message that feminist struggles are unnecessary today. At the same time, postfeminism (McRobbie, 2004) gains importance and demonstrates the intricacies of a neoliberal, highly individualist culture that subtly imprisons the freedoms that it is supposed to grant (Gill & Scharff, 2011). However, back in 1978, Gaye Tuchman used the expression “symbolic annihilation” to refer to how the media represented women. The author refers to a “symbolic annihilation” because sometimes it is so hidden and subtle that it becomes difficult to perceive – and to be fought. Much has improved since then; yet a lot remains the same. Over the past decades there have been marked changes in gender relations, in feminist activism, in the (media) communication industry and in society in general (Byerly, 2013; Carter, Steiner & McLaughlin, 2015; Gallagher, 2014; Gallego, 2013; Krijnen, Álvares & Van Bauwel, 2011; Krijnen & Van Bauwel, 2015; Lobo, Silveirinha, Subtil, & Torres, 2015; Ross, 2009; Silveirinha, 2001; Van Zoonen, 1994, 2010). Now, in a globalised and media saturated world, the gendered picture is, consequently, different. The contemporary grammar is marked by diverse and complex tensions (van Zoonen, 2010).

Contribution to an efficient transmission of information to the textile fashion consumer and the influence in sustainable attitudes

The concepts involved in sustainable textile fashion, demanding good knowledge about raw materials, processes, end use properties and circuits amongst others, are able to determine the way the textile product is designed and the behavior of the consumer, regarding life style and buying decisions. The textile product`s life integrates raw materials, their processing, distribution, use by the consumer and destination of the product after useful lifetime, this is, his complete life cycle. It is very important to recognize the power of the consumer to influence parameters related to sustainability, namely when he decides how, when and why he buys and afterwards by the attitudes taken during and after use. The conscious act of consumption involves ethical, ecological and technical knowledge in which the concern is overall lifecycle of the fashion product and not exclusively aesthetic and symbolic values strongly related with its ephemeral nature. The present work proposes the classification of textile products by means of an innovative label aiming to establish a rating related to the Life of Fashion Products, by using parameters considered with especial impact in lifecycle, as textile fibers, processing conditions, generated wastes, commercialization circuits, durability and cleaning procedures. This label for sustainable fashion products aims to assist the stakeholders with informed attitudes and correct decisions in order to promote the objectives of sustainable fashion near designers, consumers and industrial experts.
