As reações do mercado acionista e obrigacionista dos GIPSI às notícias da Troika durante o período de crise financeira: 2010-2013

Mestrado em GestãoA zona euro e mais concretamente o conjunto de países constituído por Grécia, Itália, Portugal, Espanha e Irlanda chamado de GIPSI, atravessam uma das maiores crises desde a Grande Depressão. De forma a ajudar estes países mais afetados, um conjunto de organizações internacionais (FMI/BCE/CE) apelidado de Troika, tem unido esforços para debelar as dificuldades de financiamento e criarem políticas de reforma com o objetivo de devolver a independência e potenciar o crescimento económico dos mesmos. As ações e comunicados destas organizações passaram assim a gozar de uma maior visibilidade e interesse por parte dos investidores. Tendo isso em conta, neste trabalho estudamos o impacto das notícias da Troika nos mercados acionista e obrigacionista dos GIPSI, com um maior foco no mercado português. Em Portugal não encontramos evidência de que as notícias diretamente relacionadas com as ações e comunicações da Troika têm efetivamente impactos significativos, quer no mercado acionista, quer no obrigacionista. No entanto, as notícias de carácter internacional sobre a crise, respeitantes aos outros países afetados, impactaram de forma significativa o PSI 20, especialmente quando estas foram boas, assim como outras notícias relativas a avaliações, anúncios de apoio ou críticas de outras organizações europeias e mundiais, bem como como de líderes de países intervenientes na ajuda aos países afetados e anúncios macroeconómicos, sendo que aqui esse impacto foi mais sentido nas más notícias. No mercado obrigacionista, voltamos a ter impactos significativos dos mesmos tipos de notícias juntando-se aqui as notícias relativas às medidas tomadas pelo Governo português e outros agentes governamentais. Os restantes mercados, Espanha e Grécia apresentaram impactos significativos no mercado acionista e obrigacionista, o que nos leva a confirmar estudos anteriores de que notícias relacionadas com a crise têm efeitos para além do país visado e impactam de forma significativa outros mercados, em especial os mais afetados.The euro zone and more specifically the group of countries formed by Greece, Italy, Portugal, Spain and Ireland called GIPSI, are crossing one of the biggest crises since the Great Depression. In order to help these most affected countries, a set of international organizations (IMF/ECB/EC) known as Troika, have joined efforts to tackle the financing difficulties and create political reforms in order to restore the independence and economic growth of the mentioned countries. For this reason, the actions and communications of these organizations have been enjoying greater visibility and interest from investors. Taking this into account, in this work we study the impact of the news of Troika on stock and bond markets of GIPSI countries, with a greater focus on the Portuguese market. In Portugal we found no evidence that the news directly related to the actions and communications of Troika had significant impacts, both in the stock and bond market. However, the news of an international character of the crisis, relating to other affected countries, significantly impacted the PSI 20, especially when they were good news, as well as other news related with assessments or announcements of support or criticism from other European and global organizations and leaders of countries involved in helping the affected countries and macroeconomic announcements. Here however, the impact was greater in the bad news case. In the bond market, again we find significant effects of the same types of news as well as news on the measures taken by the Portuguese Government and other government agents. In the other markets, Spain and Greece have significant impacts on stock and bond market, which leads us to confirm previous studies that news related to the crisis have effects beyond the targeted country and significantly impact other markets, particularly the most affected ones

Educação pró-envelhecimento ativo - Geron...quê?! Estudo de intervenção com estudantes portugueses

Ageing is an undeniable reality in the contemporary world, with repercussions in various areas of society. In the Western world, ageing and old age are accompanied by ageism or gerontophobia, being older people perceived as fragile society contributors to the economy and the aging associated with very negative connotations. This view permeates the society, being children affected from an early age, which tends to perpetuate the ageism or gerontophobia. In this context, emerge the paradigm of active ageing, in which education has a major role. Education and educational programmes targeted at the general population, with special attention to young people, can help to change the vision of society on aging and old age. On the above, this study aimed to plan, implement and evaluate an educational program on active ageing for students of the 9th grade of schooling in Portugal. It was accomplished through an intervention study of mixed nature, with 47 young people from a basic school of the District of Aveiro, Portugal. The data were collected through participant observation and questionnaire and analysed based on content analysis, and descriptive and inferential statistics. The educational program consisted of five sessions, on the theoretical axes: i) to age actively and with greater quality of life; II) Gerontology as knowledge area and profession that focuses on the ageing process in General; and iii) creating a friendly society of the old people. The evaluation considered the qualitative and quantitative aspects. In general, the data show that the implementation of the educational program was positive. The interest of the students on the topic of ageing has exceeded expectations. There was an evolution of knowledge on the part of students and there has been a tendency on the part of young people to face the ageing of a more positive way. In addition, the study allowed researchers to overcome their own prejudices against the young people. The results obtained show that educational programmes in the area could play a key role in eliminating prejudices about ageing, and in the preparation of the young for active ageing, with extremely positive social and economic repercussions.El envejecimiento es una realidad innegable en el mundo contemporáneo, con repercusiones en diferentes ámbitos de la sociedad. En el mundo occidental, envejecimiento y vejez son acompañados por edadismo o gerontophobía, siendo las personas mayores percibidas como frágil colaboradores de la sociedad a la economía y el envejecimiento asociado con connotaciones muy negativas. Este punto de vista impregna la sociedad, siendo los niños afectados desde una edad temprana, que tiende a perpetuar el edadismo o gerontofobía. En este contexto, emerge el paradigma del envejecimiento activo, en el que la educación tiene un papel importante. Educación y el programas educativos dirigidos a la población en general, con especial atención a los jóvenes, pueden ayudar a cambiar la visión de la sociedad a cerca del envejecimiento y vejez. A lo anterior, este estudio pretende planificar, implementar y evaluar un programa educativo sobre el envejecimiento activo para los estudiantes de 9º grado de escolaridad en Portugal. Se logró a través de un estudio de intervención de naturaleza mixta, con 47 jóvenes de una escuela básica del distrito de Aveiro, Portugal. Los datos fueron recogidos a través de cuestionario y observación participante y análisis basado en el análisis de contenido y estadística descriptiva e inferencial. El programa educativo consistió en cinco sesiones, en los ejes teóricos: i) a la edad activa y con mayor calidad de vida; II) Gerontología como área de conocimiento y profesión que se centra en el proceso de envejecimiento en general; y iii) creación de una sociedad amigable de los ancianos. La evaluación considera los aspectos cualitativos y cuantitativos. En general, los datos muestran que la aplicación del programa educativo es positiva. El interés de los estudiantes sobre el tema del envejecimiento ha superado las expectativas. Hubo una evolución del conocimiento por parte de estudiantes y ha habido una tendencia por parte de los jóvenes para enfrentar el envejecimiento de una manera más positiva. Además, el estudio permitió investigadores superar su propia discriminación en relación con los jóvenes. Los resultados obtenidos muestran que los programas educativos en el área podrían jugar un papel clave en la eliminación de la discriminación sobre el envejecimiento y en la preparación de los jóvenes para el envejecimiento activo, con repercusiones sociales y económicas muy positivas.O envelhecimento é uma realidade incontestável no mundo contemporâneo, com repercussões em várias áreas da sociedade. No mundo ocidental, o envelhecimento e a velhice são acompanhados de atitudes idadistas e de gerontofobia, num quadro em que as pessoas idosas são percebidas como contribuintes frágeis da sociedade para a economia e o envelhecimento é associado a conotações muito negativas. Essa visão permeia a sociedade e afeta as crianças desde cedo, o que tende a perpetuar o idadismo ou a gerontofobia. Nesse contexto, surge o paradigma do envelhecimento ativo, no qual a educação tem um papel de destaque. A educação e os programas educativos direcionados à população geral, com especial atenção à população jovem, podem contribuir para mudar a visão da sociedade sobre o envelhecimento e a velhice. Este estudo teve por objetivo, planejar, implementar e avaliar um programa educativo sobre o envelhecimento ativo para estudantes do 9º grau de escolaridade em Portugal e realizou-se por intermédio de um estudo de intervenção, de natureza mista, com 47 jovens de uma escola básica do Distrito de Aveiro, Portugal. Os dados foram coletados por meio da observação participante e de questionário e foram ponderados com base na análise de conteúdo e na estatística descritiva e inferencial. O programa educativo constou de cinco sessões, tendo por eixos teóricos: i) envelhecer de forma ativa e com maior qualidade de vida; ii) gerontologia como área do saber e profissão que se foca no processo do envelhecimento em geral; e iii) criação de uma sociedade amiga das pessoas idosas. Na avaliação considerou-se os aspectos qualitativos e quantitativos. De forma geral, os dados mostram que a implementação do programa educativo foi positiva. O interesse dos estudantes sobre o tema do envelhecimento superou as expetativas. Houve uma evolução de conhecimentos por parte dos estudantes que tendem a encarar o envelhecimento de uma forma mais positiva. Além disso, o estudo permitiu aos investigadores ultrapassar os seus próprios preconceitos em relação aos jovens. Os resultados obtidos demonstram que programas educativos na área poderão desempenhar um papel fundamental na eliminação de preconceitos sobre o envelhecimento, e na preparação dos mais novos para um envelhecimento ativo, com repercussões sociais e econômicas extremamente positivas.

Genomic history of coastal societies from eastern South America

Sambaqui (shellmound) societies are among the most intriguing archaeological phenomena in pre-colonial South America, extending from approximately 8,000 to 1,000 years before present (yr bp) across 3,000 km on the Atlantic coast. However, little is known about their connection to early Holocene hunter-gatherers, how this may have contributed to different historical pathways and the processes through which late Holocene ceramists came to rule the coast shortly before European contact. To contribute to our understanding of the population history of indigenous societies on the eastern coast of South America, we produced genome-wide data from 34 ancient individuals as early as 10,000 yr bp from four different regions in Brazil. Early Holocene hunter-gatherers were found to lack shared genetic drift among themselves and with later populations from eastern South America, suggesting that they derived from a common radiation and did not contribute substantially to later coastal groups. Our analyses show genetic heterogeneity among contemporaneous Sambaqui groups from the southeastern and southern Brazilian coast, contrary to the similarity expressed in the archaeological record. The complex history of intercultural contact between inland horticulturists and coastal populations becomes genetically evident during the final horizon of Sambaqui societies, from around 2,200 yr bp, corroborating evidence of cultural change

Marcel, "The 2nd competition on counter measures to 2D face spoofing attacks" in International Conference on Biometrics (ICB), Madrid (Spain), 2013, 1-6As a crucial security problem, anti-spoofing in biometrics, and particularly for the face modality, has achieved great progress in the recent years. Still, new threats arrive inform of better, more realistic and more sophisticated spoofing attacks. The objective of the 2nd Competition on Counter Measures to 2D Face Spoofing Attacks is to challenge researchers to create counter measures effectively detecting a variety of attacks. The submitted propositions are evaluated on the Replay-Attack database and the achieved results are presented in this paper.The authors would like to thank the Swiss Innovation Agency (CTI Project Replay) and the FP7 European TABULA RASA Project4 (257289) for their financial support

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others
