The nuclear safety framework in the European Union after Fukushima. Egmont Paper No. 73, December 2014

Summary. On 11 March 2011, a devastating earthquake struck Japan and caused a major nuclear accident at the Fukushima Daiichi nuclear plant. The disaster confirmed that nuclear reactors must be protected even against accidents that have been assessed as highly unlikely. It also revealed a well-known catalogue of problems: faulty design, insufficient back-up systems, human error, inadequate contingency plans, and poor communications. The catastrophe triggered the rapid launch of a major re-examination of nuclear reactor security in Europe. It also stopped in its tracks what had appeared to be a ‘nuclear renaissance’, both in Europe and globally, especially in the emerging countries. Under the accumulated pressure of rising demand and climate warming, many new nuclear projects had been proposed. Since 2011 there has been more ambivalence, especially in Europe. Some Member States have even decided to abandon the nuclear sector altogether. This Egmont Paper aims to examine the reactions of the EU regarding nuclear safety since 2011. Firstly, a general description of the nuclear sector in Europe is provided. The nuclear production of electricity currently employs around 500,000 people, including those working in the supply chain. It generates approximately €70 billion per year. It provides roughly 30% of the electricity consumed in the EU. At the end of 2013, there were 131 nuclear power reactors active in the EU, located in 14 countries. Four new reactors are under construction in France, Slovakia and Finland. Secondly, this paper will present the Euratom legal framework regarding nuclear safety. The European Atomic Energy Community (EAEC or Euratom) Treaty was signed in 1957, and somewhat obscured by the European Economic Community (EEC) Treaty. It was a more classical treaty, establishing institutions with limited powers. Its development remained relatively modest until the Chernobyl catastrophe, which provoked many initiatives. The most important was the final adoption of the Nuclear Safety Directive 2009/71. Thirdly, the general symbiosis between Euratom and the International Atomic Energy Agency (IAEA) will be explained. Fourthly, the paper analyses the initiatives taken by the EU in the wake of the Fukushima catastrophe. These initiatives are centred around the famous ‘stress tests’. Fifthly, the most important legal change brought about by this event was the revision of Directive 2009/71. Directive 2014/87 has been adopted quite rapidly, and has deepened in various ways the role of the EU in nuclear safety. It has reinforced the role and effective independence of the national regulatory authorities. It has enhanced transparency on nuclear safety matters. It has strengthened principles, and introduced new general nuclear safety objectives and requirements, addressing specific technical issues across the entire life cycle of nuclear installations, and in particular, nuclear power plants. It has extended monitoring and the exchange of experiences by establishing a European system of peer reviews. Finally, it has established a mechanism for developing EU-wide harmonized nuclear safety guidelines. In spite of these various improvements, Directive 2014/87 Euratom still reflects the ambiguity of the Euratom system in general, and especially in the field of nuclear safety. The use of nuclear energy remains controversial among Member States. Some of them remain adamantly in favour, others against or ambivalent. The intervention of the EAEC institutions remains sensitive. The use of the traditional Community method remains limited. The peer review method remains a very peculiar mechanism that deserves more attention.

Determinantes da incapacidade funcional em doentes com AVC

Introdução- O Acidente Vascular Cerebral continua a ser a primeira causa de morte em Portugal, sendo também responsável pelo elevado índice de incapacidade e dependência funcional da população adulta portuguesa, afetando significativamente os aspetos da vida física, económica e social. Os processos de reabilitação continuados têm-se mostrado bastante eficazes na recuperação da independência funcional destes doentes. Assim sendo o objetivo geral deste estudo consiste em avaliar o nível de independência funcional e os fatores determinantes nesses níveis, em doentes sujeitos a programas de reabilitação continuados e doentes sem reabilitação. Métodos- O presente estudo é de carácter quantitativo, enquadrando-se num desenho de estudo descritivo transversal e analítico, no qual participaram 60 indivíduos que sofreram AVC, pertencendo 36 ao grupo experimental e 24 ao grupo de controle. A recolha de dados foi efetuada através de um questionário composto por questões de caracterização sociodemográfica, de caracterização clinica, uma escala de APGAR Familiar e uma Escala de Medida de Independência funcional (MIF). Resultados- A análise por grupos mostra que o grupo experimental é mais independente que o grupo de controle, ou seja, o nível de independência funcional é mais elevado na sua generalidade na amostra de indivíduos sujeitos a processos de reabilitação. As variáveis que influenciaram significativamente a independência funcional foram: o género (no comportamento social no G.cont),o estado civil (solteiros/viúvo mais independentes aos níveis dos cuidados pessoais, controle dos esfíncteres, mobilidade e locomoção no G. exp), habilitações académicas (maior escolaridade maior independência no G. exp) fatores de risco (doentes sem fatores de risco no G. cont são mais independentes nos cuidados pessoais, controle de esfíncteres e locomoção), indivíduos com AVC isquémico são mais independentes nos cuidados pessoais e locomoção, e os que realizaram trombólise são mais independentes nas diferentes dimensões nos dois grupos. Conclusão- As variáveis sociodemográficas e clinicas exercem influência apenas em algumas dimensões da independência funcional dos utentes após o AVC e a reabilitação desenvolvida de forma continuada, aumenta o grau de independência dos doentes diminuindo o grau de incapacidade. Palavras-chave- Acidente Vascular Cerebral, Incapacidade, Independência Funcional, Reabilitação.

O direito ao próprio direito: modelos latino-americanos de autonomia política indígena

O objetivo deste trabalho é saber se o direito indigenista, como denominarei o direito estatal que diz respeito aos povos indígenas, reconhece a legitimidade do direito indígena, como denominarei o direito produzido pelos povos indígenas, nas experiências colombiana, boliviana e brasileira. A escolha da Bolívia se justifica pelo fato de as Constituições recentes deste país e do Equador serem consideradas um novo marco do constitucionalismo pluralista ao refundarem suas ordens buscando superar a ausência indígena constituinte. Já a Colômbia se destaca entre os países que, sob a influência recente do Convênio 169, incorporaram expressamente o pluralismo jurídico em suas Constituições. A jurisprudência produzida pela Corte Constitucional do país a respeito do direito indígena é considerada exemplar e inspiradora dos desenvolvimentos mais recentes na Bolívia. O trabalho está voltado para dois aspectos do tema: a autonomia jurisdicional, ou a capacidade para julgar conflitos conforme as normas e procedimentos próprios, e os mecanismos de controle de tais decisões. A metodologia do trabalho abrange revisão bibliográfica, seleção e análise documental de decisões judiciais e textos legais. Argumento que a acomodação de autonomias políticas e ordens jurídicas de diferentes culturas depende da criação de meta-instituições e metarregras que solucionem conflitos e promovam a coordenação entre os direitos, permitindo que os grupos se relacionem de maneira equitativa, controlem a dinâmica de suas identidades culturais e se sintam parte de uma mesma comunidade política. A prática das instituições brasileiras, no entanto, está muito mais voltada a aplicar o direito estatal aos índios do que a exercer controle sobre o direito indígena, o que indica que o paradigma da assimilação prevalece sobre eventuais concepções multiculturais de Estado e sociedade, ainda que o direito legislado apresente regras que reconhecem o pluralismo jurídico. Em outras palavras, as instituições estatais enxergam os indígenas como pessoas que percorrem o caminho da incapacidade jurídica à capacidade plena à medida em que se familiarizam com a cultura dominante, e não como pessoas que podem transitar entre diferentes ordens jurídicas. Por outro lado, a experiência recente de países latino-americanos que se abriram ao pluralismo jurídico mostra um caminho difícil e repleto de questões em aberto. As que mais se destacam são a possibilidade de violações de direitos humanos por autoridades indígenas e a tensão entre centralização política e autonomia política. Em relação ao primeiro caso, o aspecto crucial é saber quem deve julgar as violações e sob quais critérios, além de evitar decisões culturalmente enviesadas. Já o segundo caso depende da superação de traços autoritários relacionados ao governo central e da predominância das estruturas estatais já consolidadas, tanto no nível central quanto no nível local, sobre as instituições mantidas pelos povos indígenas. Ainda há um descompasso entre o discurso constitucional de igualdade entre as ordens jurídicas e a prática de subordinação das ordens indígenas às instâncias estatais.

Reciprocal Prospective Associations Between Depressive Symptoms and Perceived Relationship With Parents in Early Adolescence

Objective: Adolescent depressive symptoms are associated with difficult family relationships. Family systems and interpersonal theories of depression suggest that this association could reflect a circular process in which symptoms and family functioning affect each other over time. Few longitudinal studies have tested this hypothesis, and the results of these studies have been equivocal. In this study, we examine reciprocal prospective associations in early adolescence between depressive symptoms and 2 important aspects of parent–child relationships: communication and conflict. Methods: Participants were 3862 students who annually filled out self-reports. Path analysis was used to examine prospective associations between depressive symptoms and perceived communication and conflict with parents from the age of 12 to 13 and 14 to 15 years. Independence of these associations was assessed by controlling for family context (parental separation and family socioeconomic status) and adolescent behaviour problems (delinquent behaviours and substance use). Sex differences were evaluated with multiple group analysis. Results: Reciprocal prospective associations were found between depressive symptoms and perceived conflict with parents, but not between depressive symptoms and communication with parents. Depressive symptoms were found to predict poorer communication with parents over time, but communication was not predictive of lower depressive symptoms in subsequent years. All paths were sex-invariant and independent from family context and behaviour problems. Conclusion: This study highlights the importance of considering the potential impact of adolescent symptomatology on parent–child relationships and suggests that reciprocity may characterize the association between depressive symptoms and negative aspects of parent–child relationships. The role of adolescent perceptions in the interplay between depressive symptoms and family relationships remains to be clarified.

Knots in rings - The circular knotted protein momordica cochinchinensis trypsin inhibitor-II folds via a stable two-disulfide intermediate

The aim of this work was to elucidate the oxidative folding mechanism of the macrocyclic cystine knot protein MCoTI-II. We aimed to investigate how the six-cysteine residues distributed on the circular backbone of the reduced unfolded peptide recognize their correct partner and join up to form a complex cystine-knotted topology. To answer this question, we studied the oxidative folding of the naturally occurring peptide using a range of spectroscopic methods. For both oxidative folding and reductive unfolding, the same disulfide intermediate species was prevalent and was characterized to be a native-like two-disulfide intermediate in which the Cys(1)-Cys(18) disulfide bond was absent. Overall, the folding pathway of this head-to-tail cyclized protein was found to be similar to that of linear cystine knot proteins from the squash family of trypsin inhibitors. However, the pathway differs in an important way from that of the cyclotide kalata B1, in that the equivalent two-disulfide intermediate in that case is not a direct precursor of the native protein. The size of the embedded ring within the cystine knot motif appears to play a crucial role in the folding pathway. Larger rings contribute to the independence of disulfides and favor an on-pathway native-like intermediate that has a smaller energy barrier to cross to form the native fold. The fact that macrocyclic proteins are readily able to fold to a complex knotted structure in vitro in the absence of chaperones makes them suitable as protein engineering scaffolds that have remarkable stability.

Testing the niche apportionment hypothesis with parasite communities: is random assortment always the rule?

Niche apportionment models have only been applied once to parasite communities. Only the random assortment model (RA), which indicates that species abundances are independent from each other and that interspecific competition is unimportant, provided a good fit to 3 out of 6 parasite communities investigated. The generality of this result needs to be validated, however. In this study we apply 5 niche apportionment models to the parasite communities of 14 fish species from the Great Barrier Reef. We determined which model fitted the data when using either numerical abundance or biomass as an estimate of parasite abundance, and whether the fit of niche apportionment models depends on how the parasite community is defined (e.g. ecto, endoparasites or all parasites considered together). The RA model provided a good fit for the whole community of parasites in 7 fish species when using biovolume (as a surrogate of biomass) as a measure of species abundance. The RA model also fitted observed data when ecto- and endoparasites were considered separately, using abundance or biovolume, but less frequently. Variation in fish sizes among species was not associated with the probability of a model fitting the data. Total numerical abundance and biovolume of parasites were not related across host species, suggesting that they capture different aspects of abundance. Biovolume is not only a better measurement to use with niche-orientated models, it should also be the preferred descriptor to analyse parasite community structure in other contexts. Most of the biological assumptions behind the RA model, i.e. randomness in apportioning niche space, lack of interspecific competition, independence of abundance among different species, and species with variable niches in changeable environments, are in accordance with some previous findings on parasite communities. Thus, parasite communities may generally be unsaturated with species, with empty niches, and interspecific interactions may generally be unimportant in determining parasite community structure.

Lobe growth in foliose lichen thalli

The margins of foliose lichen thalli comprise individual lobes which grow radially and divide. This results in a complex marginal structure in which lobes differing in morphology, state of division, and growth pattern are crowded together. Various aspects of the biology of these lobes are reviewed including their carbohydrate supply, morphology, pattern of division and branching, the effect of lobe overcrowding and interactions between neighbouring lobes. As the thalus grows, lobes become increasingly crowded together and this restricts further lateral growth. Restriction of lobe width may be reponsible for the changes in radial growth rate (RGR) with size observed in foliose species. Various aspects of lobe biology may be responsible for lobe growth variation including the physical independence of lobes from their neighbours, the genetic origin of the lobes, and the pattern of lobe branching. Overall symmetry of a thallus is maintained by a fluctuating pattern of growth of individual lobes in successive months together with competition for space at the margin

Intermediation for technology diffusion and user innovation in a developing rural economy:a social learning perspective

Technology intermediaries are seen as potent vehicles for addressing perennial problems in transferring technology from university to industry in developed and developing countries. This paper examines what constitutes effective user-end intermediation in a low-technology, developing economy context, which is an under-researched topic. The social learning in technological innovation framework is extended using situated learning theory in a longitudinal instrumental case study of an exemplar technology intermediation programme. The paper documents the role that academic-related research and advisory centres can play as intermediaries in brokering, facilitating and configuring technology, against the backdrop of a group of small-scale pisciculture businesses in a rural area of Colombia. In doing so, it demonstrates how technology intermediation activities can be optimized in the domestication and innofusion of technology amongst end-users. The design components featured in this instrumental case of intermediation can inform policy making and practice relating to technology transfer from university to rural industry. Future research on this subject should consider the intermediation components put forward, as well as the impact of such interventions, in different countries and industrial sectors. Such research would allow for theoretical replication and help improve technology domestication and innofusion in different contexts, especially in less-developed countries.

Non-manipulable domains for the Borda count

We characterize the preference domains on which the Borda count satises Arrow's "independence of irrelevant alternatives" condition. Under a weak richness condition, these domains are obtained by xing one preference ordering and including all its cyclic permutations ("Condorcet cycles"). We then ask on which domains the Borda count is non-manipulable. It turns out that it is non-manipulable on a broader class of domains when combined with appropriately chosen tie-breaking rules. On the other hand, we also prove that the rich domains on which the Borda count is non-manipulable for all possible tie-breaking rules are again the cyclic permutation domains.

Katalónia a következő független állam Európában? (Will Catalonia be the next independent state?)

A Katalóniában tapasztalható függetlenségi törekvések nem minősülnek csupán spanyol belügynek, komoly uniós és nemzetközi jogi vonatkozással bírnak. Különösen érdekes megvizsgálni, hogy egyes elemzők hogyan közelítik meg a potenciális függetlenedés közgazdasági összefüggéseit, előnyeit és hátrányait. A téma személyesen is érint, mivel 2012 júliusa és 2013 januárja között a barcelonai Universitat Abat Oliba CEU egyetem vendégoktatója és kutatója voltam, így első kézből tapasztaltam a téma érzékenységét. _____ The independence of Catalonia is not just simple Spanish “internal affair”, since it has serious international and European legal aspects. It is very interesting to analyse the different approaches of the parties and experts about the economic pros and cons of the potential independence. The topic is affecting me personally; because I was guest professor and researcher of the Universitat Abat Oliba CEU in Barcelona in a turbulent period from July 2012 until January 2013, so I could experience the sensitiveness of the subject.

Mother-child interactions in youth purchase decisions

This study examines the impact of mother-child interactions on youth purchase decisions with a clear focus on dependent young adults living in the parental home. Two studies were carried out using both quantitative and qualitative approaches in order to understand the characteristics of young adults’ purchase decision-making. In the first study, a survey was distributed among young adults, and in the second study, several short essays from pairs of young adults and their mothers were analysed. Findings suggest that mother-child communication has a significant impact on children’s consumer decision-making style. Furthermore, these results draw particular attention to the laissez-faire communication style, which is relevant due to both its prevalence and its influence on youth decision-making. We also conclude that the product or service category is a critical consideration when the independence of young adults is evaluated in relation to their purchases.

Xinjiang and Central Asia: Ethno-religious, political, and economic interactions

The neighboring regions of Xinjiang and Central Asia, linked historically on the famous Silk Road, later developed separately as a result of the incorporation of the former into China and the latter into the Russian Empire and Soviet Union. Thus, interaction between Xinjiang and Central Asia has been constrained by the nature of the Sino-Russian or Sino-Soviet relationship. However, the demise of the Soviet Union--which resulted in the independence of five Central Asian states--and the recent economic reforms in the People's Republic of China suggest dramatic new possibilities for interregional cooperation.^ In this thesis, an historical and comparative approach is employed to study Chinese policies in Xinjiang and Soviet policies in Central Asia, and concludes that despite several decades of separate development, the common ethnic and religious origins of the indigenous peoples and their former ties will facilitate greater interaction between the two regions. ^

Pivot or periphery? Xinjiang's regional development and Chinese-Central Asian relations at the century's end

Xinjiang, once described by Owen Lattimore as the "pivot of Asia", has played a strategically important role in China's national defense and security. Historically linked on the famous Silk Road with Central Asia, Xinjiang was crucial to East-West economic and cultural exchanges. During the period of Russian/Soviet expansion into Central Asia and Sino-Soviet rivalry, China's need for Xinjiang's defense and territorial integrity became paramount, and consequently Xinjiang's economy was relegated to the periphery.^ The demise of the Soviet Union--which resulted in the independence of five Central Asian states--and China's reform suggest dramatic new possibilities for Xinjiang's regional development as well as interregional cooperation. As China has begun to shift regional emphasis to the interior, Xinjiang's economic development will be accelerated. With the growth of Sino/Xinjiang-Central Asian relations, Xinjiang's importance will not only be borne out in terms of defense and security, but more significantly in terms of trade and economics. At the century's end and the beginning of the 21st century, Xinjiang will likely move away from the periphery and play an increasingly pivotal role in the economy. ^

Civilizing the tropics: The highlanders' failed attempt to transform the Colombian Amazon, 1850--1930

The subject of this dissertation is the nature of the environmental transformations, both symbolic and physical, that took place in Colombia between 1850 and 1930. This period begins with the attempt by the Colombian elite to leave behind colonial ties, overcome economic disorganization, and link Colombia to the international market. These efforts were part of a general project to “civilize” this tropical country. The period closes with the transition toward an industrialization and urbanization process led by the Colombian state during the 1930s. ^ Frequently, environmental studies as an academic field are dominated by biological concerns. However, most environmental thinking accepts their interdisciplinary nature. Under this framework not only spatial but also symbolic concerns are key elements in understanding environmental transformations. ^ This study finds that despite several attempts to transform the Colombian landscape physically, most of the substantive changes were localized and circumscribed to the Andean region. Other changes were mainly symbolic. This dissertation thus uses the Amazon as one of several regions that did not experience significant changes in the forest canopy. While highlanders originally dreamed of the Amazon as an untapped El Dorado, their failed attempts to exploit the region caused them to imagine it as a nightmarish “green hell”. ^ This dissertation concentrates on three pairs of concepts: tropicality/civilization, landscape/territory, and symbolic/material changes. It presents both a general vision of Colombia and case studies of three regions: Cundinamarca, and Cauca Valley are used to compare with the Amazon region that is developed at length. Whereas mainstream Colombian histories have either fixated on the Andean highlands or, in a relegated second place, on the Caribbean region, this dissertation attempts to significantly contribute to the historiography of Colombia by focusing on the largely neglected Amazonian region. ^ To understand imageries about Colombia's landscape, the dissertation relies on travel writings, chorographic descriptions and maps. It also makes uses legal documents and other published primary sources, including literary pieces and memoirs. ^
