Medidas Fonológicas em Crianças com Perturbação dos Sons da Fala. Estudo comparativo entre o português europeu e o português brasileiro.

O objetivo deste estudo é comparar as características de dois grupos de crianças com diagnóstico de Perturbação dos Sons da Fala (PSF), falantes de português europeu (PE) e falantes de português brasileiro (PB), considerando um conjunto de medidas fonológicas que incluem Percentagem de Consoantes Corretas (PCC), Percentagem de Consoantes Corretas Revista (PCC-R), Process Density Index (PDI), Índices Absolutos (IA) e Índices Relativos (IR) de Substituição, Omissão e Distorção, tipos de Processos Fonológicos e Percentagem de Acerto por Fonema (PAF). Método: Neste estudo participaram dezoito crianças com diagnóstico de Perturbação dos Sons da Fala (PSF), com idades compreendidas entre os cinco anos e dois meses e os sete anos e 11 meses, sendo doze do sexo masculino e seis do sexo feminino, divididas em dois grupos - falantes de português europeu (GPE) e falantes de português brasileiro (GPB) - emparelhadas por idade, sexo e valor de PCC. A partir da análise das transcrições fonéticas constantes nas folhas de registo de cada subteste de nomeação de cada sujeito - Teste Fonético-Fonológico - Avaliação de Linguagem Pré-Escolar (TFF - ALPE) (Mendes et al., 2009) para o português europeu, e provas de fonologia do Teste de Linguagem Infantil ABFW (Andrade et al., 2004) para o português brasileiro,- foram calculadas e comparadas as medidas fonológicas referidas, recorrendo a testes estatísticos (paramétricos e não paramétricos). Resultados: O emparelhamento do GPE com o GPB foi bem sucedido. Não existiram diferenças estatísticamente significativas nas medidas fonológicas em estudo entre o GPE e o GPB. No Estudo 1, não existiram diferenças nos tipos de erros à exceção do erro de omissão. No Estudo 2, no GPE verificamos um menor número de erros de distorção e um maior número de erros de omissão. Existem algumas particularidades devido à variante da língua, nomeadamente no processo fonológico de PAL e de DESV. Conclusão: Esta investigação permitiu realizar a comparação do GPE e do GPB com a utilização de dois instrumentos recolha de dados diferentes. Os resultados foram de encontro ao que é descrito por outros estudos nesta área de investigação. As poucas diferenças que se observaram podem ser explicadas pelas diferenças existentes entre os sistemas fonético-fonológicos das duas variedades linguísticas. É extremamente importante a metodologia de recolha de dados para a avaliação das PSF. A mais valia desta pesquisa é o contributo de indicadores clínicos para diagnóstico, prognóstico e intervenção terapêutica nas PSF.

Proving a market for a startup befor scaling using the hypothesis-driven entrepreneurship process

The year is 2015 and the startup and tech business ecosphere has never seen more activity. In New York City alone, the tech startup industry is on track to amass $8 billion dollars in total funding – the highest in 7 years (CB Insights, 2015). According to the Kauffman Index of Entrepreneurship (2015), this figure represents just 20% of the total funding in the United States. Thanks to platforms that link entrepreneurs with investors, there are simply more funding opportunities than ever, and funding can be initiated in a variety of ways (angel investors, venture capital firms, crowdfunding). And yet, in spite of all this, according to Forbes Magazine (2015), nine of ten startups will fail. Because of the unpredictable nature of the modern tech industry, it is difficult to pinpoint exactly why 90% of startups fail – but the general consensus amongst top tech executives is that “startups make products that no one wants” (Fortune, 2014). In 2011, author Eric Ries wrote a book called The Lean Startup in attempts to solve this all-too-familiar problem. It was in this book where he developed the framework for The Hypothesis-Driven Entrepreneurship Process, an iterative process that aims at proving a market before actually launching a product. Ries discusses concepts such as the Minimum Variable Product, the smallest set of activities necessary to disprove a hypothesis (or business model characteristic). Ries encourages acting briefly and often: if you are to fail, then fail fast. In today’s fast-moving economy, an entrepreneur cannot afford to waste his own time, nor his customer’s time. The purpose of this thesis is to conduct an in-depth of analysis of Hypothesis-Driven Entrepreneurship Process, in order to test market viability of a reallife startup idea, ShowMeAround. This analysis will follow the scientific Lean Startup approach; for the purpose of developing a functional business model and business plan. The objective is to conclude with an investment-ready startup idea, backed by rigorous entrepreneurial study.

Environmental quality of life index incorporationg MCA & GIS : case study Lisbon Metropolitan Area, Portugal

The study of Quality of Life (Qol) has been conducted on various scales throughout the years with focus on assessing overall quality of living amongst citizens. The main focus in these studies have been on economic factors, with the purpose of creating a Quality of Life Index (QLI).When it comes down to narrowing the focus to the environment and factors like Urban Green Spaces (UGS) and air quality the topic gets more focused on pointing out how each alternative meets this certain criteria. With the benefits of UGS and a healthy environment in focus a new Environmental Quality of Life Index (EQLI) will be proposed by incorporating Multi Criteria Analysis (MCA) and Geographical Information Systems (GIS). Working with MCA on complex environmental problems and incorporating it with GIS is a challenging but rewarding task, and has proven to be an efficient approach among environmental scientists. Background information on three MCA methods will be shown: Analytical Hierarchy Process (AHP), Regime Analysis and PROMETHEE. A survey based on a previous study conducted on the status of UGS within European cities was sent to 18 municipalities in the study area. The survey consists of evaluating the current status of UGS as well as planning and management of UGS with in municipalities for the purpose of getting criteria material for the selected MCA method. The current situation of UGS is assessed with use of GIS software and change detection is done on a 10 year period using NDVI index for comparison purposes to one of the criteria in the MCA. To add to the criteria, interpolation of nitrogen dioxide levels was performed with ordinary kriging and the results transformed into indicator values. The final outcome is an EQLI map with indicators of environmentally attractive municipalities with ranking based on predefinedMCA criteria using PROMETHEE I pairwise comparison and PROMETHEE II complete ranking of alternatives. The proposed methodology is applied to Lisbon’s Metropolitan Area, Portugal.
