Choosing the gender and skill of politicians: List composition and electability across Brazilian municipalities

This work project studies the effect of variations in the proportion of female candidates on the quality of politicians. This effect was divided between nominated and elected body. Cross-sectional data was used for two elections, and an OLS as an IV approach. Results show that the existence of female candidates on parties’ list increases the quality of the nominated body. Moreover, contrary to what many advocate, increasing the presence of female candidates either increases or has no effect on the quality of the elected body. Results that were confirmed for the overall data and controlling for region factors only.

Crowdfunding campaigns: Perceived quality and success

Research in Crowdfunding is an emerging priority within the field of Entrepreneurship. Hundreds of platforms provide nowadays multiple Crowdfunding schemes which are intended to make it easier for entrepreneurs and others to collect money from the crowd. However, only a few campaigns become successful as others don’t reach the pre-established funding goal. It is thus necessary to keep on understanding the dynamics of these platforms and the factors which justify success. The asymmetry of information has been shown to be a delicate issue as people perceive quality in different manners. As so, this research aims to understand which components of perceived quality mostly influence investments decisions. Mainly Entrepreneurship and Marketing theories were explored along the way. This is research follows a causal approach where nineteen hypotheses are tested. An experimental survey was conducted and data was collected from 127 people who were asked to evaluate one of the most important pieces of any Crowdfunding campaign – the pitch video – and consequently invest on the presented products.

Job quality in Europe: the North-South divide

This paper examines the job quality in Europe. It is based on the results of the Fourth European Foundation Survey on working conditions covering different dimensions including work organisation, job content, autonomy at work, aspects of worker dignity, working time and work-life balance, working conditions and safety in the workplace. The results point to the existence of great diversity in the job quality across Europe and the north-south divide. The job quality differences are related to the variety of social and institutional contexts. The countries of Southern Europe, with their social and institutional contexts falling within the scope of the Mediterranean model, generally present indicators below the European average contrasting Nordic countries having the best job quality indicators.

How to Measure the Deterrence Effects of Merger Policy: Frequency or Composition?

We show that the number of merger proposals (frequency-based deterrence) is a more appropriate indicator of underlying changes in merger policy than the relative anti-competitiveness of merger proposals (composition-based deterrence). This has strong implications for the empirical analysis of the deterrence effects of merger policy enforcement, and potential implications regarding how to reduce anti-competitive merger proposals.

Indicadores de qualidade para a contratualização de cuidados paliativos

RESUMO - Âmbito e objectivos: O presente trabalho incide sobre a área dos cuidados paliativos, nomeadamente, visa contribuir para uma maior efectividade do processo de aquisição e acompanhamento deste tipo de cuidados. Neste contexto, e como objectivo principal do estudo, foram identificados os indicadores chave, na vertente da qualidade, indispensáveis para a conceptualização de um modelo de contratualização e, consequentemente, para assegurar a monitorização, acompanhamento e avaliação da actividade realizada. Método e metodologias: Numa primeira fase, foi conduzida uma pesquisa documental tendente ao levantamento dos indicadores, na dimensão da qualidade, em utilização nos cuidados paliativos em vários países, tendo sido escolhidos aqueles que apresentavam indicadores já validados, designadamente, o Canadá, Reino Unido, Austrália, Espanha e EUA. Desta forma, foram seleccionados os indicadores comuns aos vários países estudados, para efeitos de discussão e consensualização, no âmbito de uma Técnica de Grupo Nominal, passíveis de integrarem um modelo de contratualização nesta área em Portugal. Apresentação e discussão de resultados: Da pesquisa documental resultaram 188 indicadores na dimensão qualidade, em utilização nos países estudados, tendo sido identificados 19 indicadores comuns. Estes indicadores foram submetidos a discussão e consensualização em reunião de peritos, tendo sido hierarquizados os sete indicadores mais adequados para a contratualização em cuidados paliativos: composição de uma equipa interdisciplinar; capacidade de resposta doentes tratados/pedido de acesso; avaliação inicial e periódica das necessidades (oito domínios); acessibilidade farmacológica; congruência entre os cuidados prestados e os desejados; prática regular de reuniões multidisciplinares; conferência familiar, pelo menos 2 vezes. Conclusões: No panorama nacional, não se conhecem indicadores unanimemente ratificados como adequados à avaliação da efectividade, qualidade e eficiência dos cuidados paliativos. Por outro lado, atento o objectivo do presente trabalho, a informação recolhida a nível internacional devolveu indicadores aplicáveis maioritariamente num contexto da avaliação da prestação dos cuidados paliativos, e Indicadores de Qualidade para a Contratualização de Cuidados Paliativos em Portugal x/ 93 não tanto num contexto de um processo de contratualização efectivo. Assim, partindo destes indicadores, em utilização nos vários países estudados, o estudo permitiu identificar sete indicadores considerados como adequados para a contratualização destes cuidados, em Portugal. -------------- ABSTRACT - Scope and objectives: This work focuses on the palliative care area, in particular, aims to contribute to greater effectiveness of the monitoring and procurement process of this type of care. In this context, as the main objective of the study, key indicators were identified regarding the quality issue, crucial to the conceptualization of a contracting model, and consequently to ensure the monitoring, supervising and evaluating of the undertaken activities. Method and methodology: Initially, a documentary research was held. That research aimed to surveying the indicators in their dimension of quality, regarding their use in palliative care throughout several countries. The chosen countries already had validated indicators, namely, Canada, United Kingdom , Australia, Spain and the USA. Thus, the indicators selected were common to all the above mentioned countries, for discussion purposes and agreement, as part of a Nominal Group Technique, that could integrate a model of contracting in this area in Portugal. Presentation and result discussion: The documentary research resulted in 188 quality indicators in use in the referred countries, 19 of those indicators were common to all countries. These indicators were submitted for discussion and agreement at a meeting of experts, having been ranked the seven most appropriate indicators for palliative care contracting: composition of an interdisciplinary team; response ability to the patients / access requests, initial and periodic assessment of the needs (eight areas), pharmacology accessibility; congruence between the desired care and its effective provision and regular practice of multidisciplinary meetings, family conferences, at least two times. Conclusions: In the national scene, unanimously ratified as suitable indicators to assess the effectiveness, efficiency and quality of palliative care are unknown. On other hand, given the objective of this work, the international collection of information has given applicable indicators mostly in the context of assessing the provision of palliative care, rather than an effective contracting process context. Thus, based on these indicators in use in the studied countries, the study itself identified seven indicators considered appropriate for the contracting of such care in Portugal.

The clothing industry as a globalized sector: implications for work organisation, quality of work and job content

The clothing sector in several countries is still seen, in many aspects as a traditional sector with some average characteristics, nevertheless is a very important sector in terms of labour market. Globalization and de-localization are having a strong impact in the organisation of work and in occupational careers. Very few companies are able to keep a position in the market without changes in organisation of work and workers, founding different ways to face this reality according to size, capital and position. We could find two main paths: one where companies outsource production to another territory, close and/ or dismissal the workers; other path, where companies up skilled their capacities. This paper will present some results from the European project WORKS – Work organisation and restructuring in the knowledge society (6th Framework Programme), focusing the Portuguese case studies in several clothing companies in a comparative analysis with some other European countrie

The role of ribonuclease R in bacterial adaptation to cold shock

RESUMO:Os microrganismos reagem à súbita descida de temperatura através de uma resposta adaptativa específica que assegura a sua sobrevivência em condições desfavoráveis. Esta adaptação inclui alterações na composição da membrana, na maquinaria de tradução e transcrição. A resposta ao choque térmico pelo frio induz uma repressão da transcrição. No entanto, a descida de temperatura induz a produção de um grupo de proteínas específicas que ajudam a ajustar/re-ajustar o metabolismo celular às novas condições ambientais. Em E. coli o processo de adaptação demora apenas quatro horas, no qual um grupo de proteínas específicas são induzidas. Depois desde período recomeça lentamente a produção de proteínas.A ribonuclease R, uma das proteínas induzidas durante o choque térmico pelo frio, é uma das principais ribonucleases em E. coli envolvidas na degradação do RNA. É uma exoribonuclease que degrada RNA de cadeia dupla, possui funções importantes na maturação e “turnover” do RNA, libertação de ribossomas e controlo de qualidade de proteínas e RNAs. O nível celular desta enzima aumenta até dez vezes após exposição ao frio e estabiliza em células na fase estacionária. A capacidade de degradar RNA de dupla cadeia é importante a baixas temperaturas quando as estruturas de RNA estão mais estáveis. No entanto, este mecanismo é desconhecido. Embora a resposta específica ao “cold shock” tenha sido descoberta há mais de duas décadas e o número de proteínas envolvidas sugerirem que esta adaptação é rápida e simples, continuamos longe de compreender este processo. No nosso trabalho pretendemos descobrir proteínas que interactuem com a RNase R em condições ambientais diferentes através do método “TAP-tag” e espectrometria de massa. A informação obtida pode ser utilizada para deduzir algumas das novas funções da RNase R durante a adaptação bacteriana ao frio e durante a fase estacionária. Mais importante ainda, RNase R poderá ser recrutada para um complexo de proteínas de elevado peso molecular durante o “cold-shock”.------------ABSTRACT:Microorganisms react to the rapid temperature downshift with a specific adaptative response that ensures their survival in unfavorable conditions. Adaptation includes changes in membrane composition, in translation and transcription machinery. Cold shock response leads to overall repression of translation. However, temperature downshift induces production of a set of specific proteins that help to tune cell metabolism and readjust it to the new environmental conditions. For Escherichia coli the adaptation process takes only about four hours with a relatively small set of specifically induced proteins involved. After this time, protein production resumes, although at a slower rate. One of the cold inducible proteins is RNase R, one of the main E. coli ribonucleases involved in RNA degradation. RNase R is an exoribonuclease that digest double stranded RNA, serves important functions in RNA maturation and turnover, release of stalled ribosomes by trans-translation, and RNA and protein quality control. The level of this enzyme increases about ten-fold after cold induction, and it is also stabilised in cells growing in stationary phase. The RNase R ability to digest structured RNA is important at low temperatures where RNA structures are stabilized but the exact role of this mechanism remains unclear. Although specific bacterial cold shock response was discovered over two decades ago and the number of proteins involved suggests that this adaptation is fast and simple, we are still far from understanding this process. In our work we aimed to discover the proteins interacting with RNase R in different environmental conditions using TAP tag method and mass spectrometry analysis. The information obtained can be used to deduce some of the new functions of RNase R during adaptation of bacteria to cold and in stationary growth phase. Most importantly RNase R can be recruited into a high molecular mass complex of protein in cold shock.
