En la sociedad actual se recibe tanta información que puede darse la paradoja de que el ciudadano no esté bien informado. En este trabajo, tras una breve revisión de la literatura más reciente sobre la calidad del producto informativo, se propone un indicador de calidad para los programas informativos de televisión, el índice de afinidad (IA). Este índice se define como la medida de la adecuación del programa informativo a los intereses del espectador, considerando como tales las preocupaciones de los ciudadanos que el Centro de Investigaciones Sociológicas (CIS) recoge en su barómetro mensual. En síntesis, se procederá a medir un aspecto de la calidad de los informativos, teniendo en cuenta la adecuación a los intereses del público. Para el estudio, se ha escogido una muestra de programas informativos emitidos en Antena 3 y Telecinco, en el momento de máxima audiencia - 21:00 horas- en el año 2011. Se han seleccionado estos dos canales por ser los de mayor audiencia dentro de las compañías privadas en España. Se obtiene como resultado que el IA de Antena 3 es normalmente superior al de Telecinco, aunque en ambas cadenas el valor del índice disminuye considerablemente en los programas del fin de semana.

A cidade de Porto Seguro que se localiza no Brasil, no sul da Bahia, apresenta potencial de grande atração turística. O turismo em Porto Seguro é marcado por contradições que potencializam desigualdades e violências, associadas ao tráfico de drogas. Tal paradoxo eleva Porto Seguro a décima posição entre as cidades mais violentas do Brasil, situação de vulnerabilidade social, negação de direitos humanos e efetivação de um turismo predatório. O trabalho compreende pontualmente os dois lados desta situação, o primeiro apresenta a fetichização de Porto Seguro como um lugar idílico, o outro lado apresenta os elevados índices de criminalidade ligada ao tráfico de drogas. A metodologia deste estudo utilizou o cruzamento de dados estatísticos oficiais e pesquisas de campo. O estudo conclui que há um grande abismo entre a cidade ideal vendida e fetichizada como paraíso turístico reificado por uma mídia mercantil, e a cidade real ignorada por esta mesma mídia, e onde a população vive ao meio de um fogo cruzado que se monta e um diagrama de controles negociados, ilegalismos na expansão do tráfico de drogas e de uma economia ilícita que se inclui na economia turística.

In July 2011, the European Commission published a Communication aimed at setting out different options for establishing a European terrorist finance tracking system (TFTS). The Communication followed the adoption of the EU-US agreement on the US Terrorist Finance Tracking Program (TFTP) in 2010. The agreement concluded various series of national, European and transatlantic negotiations after the disclosure through public media of the US TFTP in 2006. This paper takes stock of the wide range of controversies surrounding this security-focused programme with dataveillance capabilities. After stressing the impact of the US TFTP on international relations, the paper argues that the EU-US agreement primarily has the effect of shifting information-sharing practices from the justice/judicial/penal/criminal investigation framework into the security/intelligence/administrative/prevention context as the main rationale. The paper then questions the TFTP-related conception of mass intelligence through large-scale databases and transnational communication of bulk data in the name of targeted surveillance. Following an examination of the project creating an EU system equivalent to the TFTP, the paper emphasises the fundamental paradox of transatlantic security matters, in which European criticism of American programmes tends to be ultimately translated into EU imitation of US dataveillance practices.

Agriculture in the Republic of Moldova is an important economic sector, accounting for 41% of Moldovan exports and employing 1.3 million people, a large share of the working population. The EU has surpassed Russia as Moldova’s main commercial partner (54% of its exports go to the EU). It is a paradox that the Soviet inheritance still dictates economic trends: the heavy industrialised Transnistria exports, as a percentage, more into the EU than the rest of Moldova does. The right-bank Moldova was designed by Soviet planners as an agricultural basket while Transnistria, on the left bank of the Dniester River, concentrated the heavy industry. As such, from time to time, Russia strikes Moldova where it hurts, with embargos on food and agricultural products

Mutual recognition is a remarkable innovation facilitating economic intercourse across borders. In the EU's internal goods market it has been helpful in tackling or avoiding the remaining obstacles, namely, regulatory barriers between Member States. However, there is a curious paradox. Despite the almost universal acclaim of the great merits of mutual recognition the principle has, in and by itself, contributed only modestly to the actual realisation of free movement in the single market. It is also surprising that economists have not or hardly underpinned their widespread appreciation for the principle by providing rigorous analysis which could substantiate the case for mutual recognition for policy makers. Business in Europe has shown a sense of disenc hantment with the principle because of the many costs and uncertainties in its application in actual practice. The purpose of the present paper is to provide the economic and strategic arguments for employing mutual recognition much more systematically in the single market for goods and services. The strategic and the "welfare" gains are analysed and adetailed exposition of the fairly high information , transaction and compliance costs is provided. The information costs derive from the fact that mutual recognition remains a distant abstraction for day-to-day business life. Understandably, verifying the "equivalence" of objectives of health and safety between Member States is perceived as difficult and uncertain. This sentiment is exacerbated by the complications of interpreting the equivalence of "effects". In actual practice, these abstractions are expected to override clear and specific national product or services rules, which local inspectors or traders may find problematic without guidance. The paper enumerates several other costs including, inter alia, the absence of sectoral rule books and the next-to-prohibitive costs of monitoring of the application of the principle. The basic problems in applying mutual recognition in the entire array of services are inspected, showing why the principle can only be used in a limited number of services markets and even there it may contribute only modestly to genuine free movement and competitive exposure. A special section is devoted to a range of practical illustrations of the difficulties business experiences when relying on mutual recognition. Finally, the corollary of mutual recognition - regulatory competition - is discussed in terms of a cost/benefits analysis compared to what is often said to be the alternative , that is "harmonisation" , in EU parlance the "new approach" to approximation. The conclusion is that the manifold benefits of mutual recognition for Europe are too great to allow the present ambiguities to continue. The Union needs much more pro-active approaches to reduce the costs of mutual recognition as well as permanent monitoring structures for its application to services (analogous to those already successfully functioning in goods markets). Above all, what is required is a "mutual recognition culture" so that the EU can better enjoy the fruits of its own regulatory ingenuity.

Introduction. On October 26, 2014, Tunisia held its second democratic legislative elections. Participation among more than 5 million registered voters was at about 60%, a relatively good turnout for the country, compared to the 52% voters in 2011. Preliminary results for the 33 constituencies (27 within the country and 6 for expatriates) reveal that secular frontrunner Nidaa Tounes (Call of Tunisia) won around 37% percent of votes while moderate Islamist party Ennahdha, winner of the 2011 elections and leader of Tunisia’s post-revolution government, received 27% of votes. Other parties with notable percentages are the Free Patriotic Union (French: UPL) with 4.4% and the leftist party, Popular Front, with 3.7%. Legislative were immediately followed by two round presidential elections the first one held on November 23, the second one after one month. Conversely to what was expected, people were more attracted by presidential elections even though president has notably less prerogatives than the parliament: representing the state, he is mainly responsible for determining the general state policies in the domains of defense, foreign relations and national security (article 76.) This paradox is ascribed to national imaginary more confident in a “Zaïm” (leader) rather than a collective institution such as a parliament. The turnout was at about 64% within the national 27 constituencies. Out of 70 candidates (including 5 female), 27 (with only one female) met the legal requirements to run for the presidency. The result confirms the legislative trend and Beji Caid Essebsi, leader of Nidaa, was proclaimed the third President of Tunisia. He gained 39.46% of the votes at the first round elections. Essebsi was followed by Moncef Marzouki who received an unexpected score (33.43%) at the first round, thanks to the support of Ennahdha audience and to an active and insistent campaign focused on the idea that revolution is threatened by old regime guard “come-back.” Rewarded for his long militant live, the extreme leftist Hamma Hammami in a new look gained 7,8% of the votes while the new comer Slim Riahi received 5,5% despite rumors circulating on his personal reputation. Notably, Kalthoum Kennou gained 0,55% (18.287 votes) but listed eleventh out of 27.

Are we witnessing a crisis of democratic legitimacy? While citizens may lose trust in political authorities, democratic principles and ideals continue to exercise considerable appeal. This Policy Brief argues that this paradox must be understood as a crisis of legitimation. Research suggests that legitimacy is inherently subjective and must be constantly re-earned. Low levels of political trust can be explained as the result of the complexity of globalised yet fragmented societies. The present feeling of malaise calls for a redefinition of the relationship between citizens and the authorities by which they are ruled. If popular sovereignty is to mean anything in today’s age, it requires a new legitimising narrative.

Summary. Energy saving has been a stated policy objective of the EU since the 1970s. Presently, the 2020 target is a 20% reduction of EU energy consumption in comparison with current projections for 2020. This is one of the headline targets of the European Energy Strategy 2020 but efforts to achieve it remain slow and insufficient. The aim of this paper is to understand why this is happening. Firstly, this paper examines the reasons why public measures promoting energy efficiency are needed and what form these measures should optimally take (§ 1). Fortunately, over the last 20 years, much research has been done into the famous ‘energy efficiency gap’ (or ‘the energy efficiency paradox’), even if more remains to be done. Multiple explanations have been given: market failures, modelling flaws and behavioural obstacles. Each encompasses many complex aspects. Several types of instruments can be adopted to encourage energy efficiency: measures guaranteeing the correct pricing of energy are preferred, followed by taxes or tradable white certificates which in turn are preferred to standards or subsidies. Information programmes are also necessary. Secondly, the paper analyzes the evolution of the different programmes from 2000 onwards (§ 2). This reveals the extreme complexity of the subject. It deals with quite diverse topics: buildings, appliances, public sector, industry and transport. The market for energy efficiency is as diffuse as energy consumption patterns themselves. It is composed of many market actors who demand more efficient provision of energy services, and that suppliers of the necessary goods and know-how deliver this greater efficiency. Consumers in this market include individuals, businesses and governments, and market activities cover all energy-consuming sectors of the economy. Additionally, energy efficiency is the perfect example of a shared competence between the EU and the Member States. Lastly, the legal framework has steadily increased in complexity, and despite the successive energy efficiency programmes used to build this framework, it has become clear that the gap between the target and the results remains. The paper then examines whether the 2012/27/EU Directive adopted to improve the situation could bring better results. It briefly describes the content of this framework Directive, which accompanies and implements the latest energy efficiency programme (§ 3). Although the Directive is technically complex and maintains nonbinding energy efficiency targets, it certainly represents an improvement in several aspects. However, it is also saddled with a multiplicity of exemption clauses and interpretative documents (with no binding value) which weaken its provisions. Furthermore, alone, it will allow the achievement of only about 17.7% of final energy savings by 2020. The implementation process, which is essential, also remains fairly weak. The paper also gives a glimpse of the various EU instruments for financing energy efficiency projects (§ 4). Though useful, they do not indicate a strong priority. Fourthly, the paper tries to analyze the EU’s limited progress so far and gather a few suggestions for improvement. One thing seems to remain useful: targets which can be defined in various ways (§ 5). Basically, all this indicates that the EU energy efficiency strategy has so far failed to reach its targets, lacks coherence and remains ambiguous. In the new Commission’s proposals of 22 January 2014 – intended to define a new climate/energy package in the period from 2020 to 2030 – the approach to energy efficiency remains unclear. This is regrettable. Energy efficiency is the only instrument which allows the EU to reach simultaneously its three targets: sustainability, competitiveness and security. The final conclusion appears thus paradoxical. On the one hand, all existing studies indicate that the decarbonization of the EU economy will be absolutely impossible without some very serious improvements in energy efficiency. On the other hand, in reality energy efficiency has always been treated as a second zone priority. It is imperative to eliminate this contradiction.

There is a puzzling, little-remarked contradiction in scholarly views of the European Commission. On the one hand, the Commission is seen as the maestro of European integration, gently but persistently guiding both governments and firms toward Brussels. On the other hand, the Commission is portrayed as a headless bunch of bickering fiefdoms who can hardly be bothered by anything but their own in ternecine turf wars. The reason these very different views of the same institution have so seldom come into conflict is quite apparent: EU studies has a set of relatively autonomous and poorly integrated sub fields that work at different levels of analysis. Those scholars holding the "heroic" view of the Com mission are generally focused on the contest between national and supranational levels that character ized the 1992 program and subsequent major steps toward European integration. By contrast, those scholars with the "bureaucratic politics" view are generally authors of case studies or legislative his tories of individual EU directives or decisions. However, the fact that these twO images of the Commis sion are often two ships passing in the night hardly implies that there is no dispute. Clearly both views cannot be right; but then, how can we explain the significant support each enjoys from the empirical record? The CommiSSion, perhaps the single most important supranational body in the world, certainly deserves better than the schizophrenic interpretation the EU studies community has given it. In this paper, I aim to make a contribution toward the unraveling of this paradox. In brief, the argument I make is as follows: the European Commission can be effective in pursuit of its broad integration goals in spite of, and even because of, its internal divisions. The folk wisdom that too many chefs spoil the broth may often be true, but it need not always be so. The paper is organized as follows. 1 begin with an elaboration of the theoretical position briefly out lined above. 1 then tum to a case study from the major Commission efforts to restructure the computer industry in the context of its 1992 program. The computer sector does not merely provide interesting, random illustrations of the hypothesis 1 have advanced. Rather, as Wayne Sandholtz and John Zysman have stressed, the Commission's efforts on informatics formed one of the most crucial parts of the en tire 1992 program, and so the Commission's success in "Europeanizing" these issues had significant ripple effects across the entire European political economy. I conclude with some thoughts on the fol lowing question: now that the Commission has succeeded in bringing the world to its doorstep, does its bureaucratic division still serve a useful purpose?

Des recherches au Québec (Garon, 2009), en France (Donnat, 2011) et aux États-Unis (Kolb, 2001) confirment un état de fait général: le vieillissement du public de la musique classique. Si le public du répertoire est reconnu pour posséder un haut niveau d’études, pourquoi les étudiants universitaires de nos jours ne sont-ils pas plus présents dans les salles de concert ? Cette étude explore cette problématique d’abord par une recherche historique et par des entrevues auprès de certains des organismes de musique classique à Montréal, et ce afin de comprendre leurs stratégies de développement des publics concernés de 2004 à 2014. Ensuite, par un sondage auprès de 555 étudiants universitaires de la ville, pour faire un portrait de leur relation avec la musique à l’heure actuelle. Notre analyse, appuyée par une bibliographie en sociomusicologie et en sociologie des pratiques culturelles, confirme des tendances comme celle de l’«omnivorisme culturel» et l’éclectisme musical des jeunes universitaires. Elle nous montre aussi une réception positive des œuvres classiques, quoiqu’incompatible avec les critères esthétiques des genres musicaux favoris. À partir de ce paradoxe, nous étudions la force des motivations extramusicales qui les amènent aux concerts, leurs formats préférés, l’impact de l’éducation musicale, l’influence des parents, de l’internet, des nouvelles technologies. Finalement, nous constatons le nombre peu élevé d’initiatives des organismes musicaux dans le milieu universitaire à Montréal qui, pourtant, se montre un bassin au grand potentiel pour le renouvellement des publics de la musique classique.

The quantity, type, and maturity of the organic matter of Quaternary and Tertiary sediments from the Japan Trench (DSDP Leg 56, Sites 434 and 436; and Leg 57, Sites 438, 439 and 440) were determined. The hydrocarbons in lipid extracts were analyzed by capillary- column gas chromatography and combined gas chromatography/ mass spectrometry. Kerogen concentrates were investigated by microscopy, and vitrinite-reflectance values were determined. Measured organic-carbon values were in the range of 0.13 to 1.00 per cent. Extract yields, however, were extremely low. Normalized to organic carbon, total extracts ranged from 4.1 to 15.7 mg/g Corg. Gas chromatography of non-aromatic hydrocarbons showed that all sediments, except one Oligocene sample, contained very immature, mainly terrigenous organic material. This was indicated by n-alkane maxima at C29 and C31 and high odd-carbon-number predominances. Unsaturated steroid hydrocarbons were found to be major cyclic compounds in lower- and middle-Miocene samples from the upper inner trench slope (Sites 438 and 439). Perylene was the dominating aromatic hydrocarbon in all but the Oligocene sample. Microscopy showed kerogens rich in terrigenous organic particles, with a major portion of recycled vitrinite. Nevertheless, almost all the liptinite particles appeared to be primary. This is a paradox, as the bulk of the samples were composed of hemipelagic mineral matter with a major siliceous biogenic (planktonic) component. A trend of reduced size and increased roundness can be seen for the vitrinite/ inertinite particles from west to east (from upper inner trench slope to outer trench slope). All sediments but one are relatively immature, with mean huminite-reflectance values (Ro)in the range of 0.30 to 0.45 per cent. The oldest and deepest sediment investigated, an Oligocene sandstone from Site 439, yielded a mean vitrinitereflectance value of 0.74 per cent and a mature n-alkane distribution. This sample may indicate a geothermal event in late Oligocene time. It failed to affect the overlying lower Miocene and may have been caused by an intrusion. Boulders of acidic igneous rocks in the Oligocene can be interpreted as witnesses of nearby volcanic activity accompanied by intrusions.

Blue whiting (Micromesistius poutassou, http://www.marinespecies.org/aphia.php?p=taxdetails&id=126439) is a small mesopelagic planktivorous gadoid found throughout the North-East Atlantic. This data contains the results of a model-based analysis of larvae captured by the Continuous Plankton Recorder (CPR) during the period 1951-2005. The observations are analysed using Generalised Additive Models (GAMs) of the the spatial, seasonal and interannual variation in the occurrence of larvae. The best fitting model is chosen using the Aikaike Information Criteria (AIC). The probability of occurrence in the continous plankton recorder is then normalised and converted to a probability distribution function in space (UTM projection Zone 28) and season (day of year). The best fitting model splits the distribution into two separate spawning grounds north and south of a dividing line at 53 N. The probability distribution is therefore normalised in these two regions (ie the space-time integral over each of the two regions is 1). The modelled outputs are on a UTM Zone 28 grid: however, for convenience, the latitude ("lat") and longitude ("lon") of each of these grid points are also included as a variable in the NetCDF file. The assignment of each grid point to either the Northern or Southern component (defined here as north/south of 53 N), is also included as a further variable ("component"). Finally, the day of year ("doy") is stored as the number of days elapsed from and included January 1 (ie doy=1 on January 1) - the year is thereafter divided into 180 grid points.
