Análisis numérico del comportamiento vibratorio del conjunto móvil de un altavoz dinámico

En este trabajo se describe el proceso llevado a cabo para analizar numéricamente mediante el método de los elementos finitos (MEF) el comportamiento vibratorio del conjunto móvil de un altavoz dinámico de bobina con doble suspensión inferior y en ausencia de la superior. El estudio se centra en el rango de baja frecuencia. El calibrado del modelo se realiza en base a medidas experimentales de la frecuencia de resonancia y desplazamiento del diafragma. Se hace énfasis en la importancia de los factores de participación asociados a la fuerza de excitación y en los cambios que se producen en estos al introducir fuerzas no equilibradas. Así mismo, el análisis proporciona datos para decidir sobre la distancia entre suspensiones, su número óptimo de pliegues y la ubicación de las trencillas, siendo estos parámetros de gran interés en el diseño de este tipo de altavoces.

«Soy vampiro, pero también una chica»: vampiros regenerados en True Blood

En la literatura y el cine góticos clásicos, el vampiro se concebía como un monstruo al que cabía eliminar. Sin embargo, en los últimos cuarenta años, novelas, películas y series revelan una voluntad de asimilarlo a la sociedad humana, un proceso conocido como domesticación o regeneración. Como metáfora de la diferencia sexual, racial, de género o de clase, tal asimilación representa, de acuerdo con los postulados de Foucault, una operación que lleva a cabo el poder para someterlas, integrándolas en el orden social y cultural establecido. La serie estadounidense True Blood (2008-2014) refleja a la perfección este proceso dual de regeneración que implica, a su vez, sometimiento. Relacionado con los supuestos de la corrección política, el nuevo monstruo ya no simboliza al «perverso» sino al «diferente» que se debe proteger y aceptar en el seno de la sociedad, pese al riesgo de cohesión social y amenaza para la familia que comporta.

The Report of the Committee appointed to Consid'n of the Memorial of the Overseers of Harvard College, 1722 June 29

Two folio-sized leaves containing a handwritten copy of a June 29, 1722 report created by a Committee of the General Court responding to the June 13, 1722 memorial of the Board of Overseers. The report lists three points declaring that the Charter of 1650 intended the Tutors to be members of the Corporation "provided they exceed not five in number," that none of the Fellows be Overseers, and that the Charter of 1650 did not grant the Corporation the power to set salaries without the consent of the Overseers. The copy notes that the report was read and accepted on June 29, and signed by Governor Samuel Shute on July 2, 1722, with the stipulation that none of the current non-resident Fellows be removed from the Corporation.

Letter from Samuel Willard, Deerfield, Massachusetts, to Catherine Willard, Petersham, Massachusetts, July 28, 1808

Willard apologizes for not writing or visiting in a long time, discusses a problem with getting his sister Sophronia to visit in Deerfield, and writes: “I think I have a wife, who will do everything in her power to make me happy.”

European antitrust control and standard setting. Bruegel Working Paper 2013/01, February 2012

Standards reduce production costs and increase products’ value to consumers. Standards however entail risks of anti-competitive abuse. After the adoption of a standard, the chosen technology normally lacks credible substitutes. The owner of the patented technology might thus have additional market power relative to locked-in licensees, and might exploit this power to charge higher access rates. In the economic literature this phenomenon is referred to as ‘hold-up’. To reduce the risk of hold-up, standard-setting organisations often require patent holders to disclose their standard-essential patents before the adoption of the standard and to commit to license on fair, reasonable and non-discriminatory (FRAND) terms. The European Commission normally investigates unfair pricing abuse in a standard-setting context if a patent holder who committed to FRAND ex-ante is suspected not to abide to it ex-post. However, this approach risks ignoring a number of potential abuses which are likely harmful for welfare. That can happen if, for example, ex-post a licensee is able to impose excessively low access rates (‘reverse hold-up’) or if a patent holder acquires additional market power thanks to the standard but its essential patents are not encumbered by FRAND commitments, for instance because the patent holder did not directly participate to the standard setting process and was therefore not required by the standard-setting organisations to commit to FRAND ex-ante. A consistent policy by the Commission capable of tackling all sources of harm should be enforced regardless of whether FRAND commitments are given. Antitrust enforcement should hinge on the identification of a distortion in the bargaining process around technology access prices, which is determined by the adoption of the standard and is not attributable to pro-competitive merits of any of the involved players.

A acção de condenação à prática de acto devido : conhecimento e prova dos pressupostos de facto do acto

A acção de condenação à prática de acto devido corresponde à concretização, com o Código de Processo nos Tribunais Administrativos, do princípio da tutela jurisdicional efectiva previsto no art. 268º/4 da Constituição da República Portuguesa, assegurando aos particulares a obtenção de uma pronúncia condenatória na prática do acto administrativo que tenha sido recusado ou omitido. Esta pronúncia sofre as limitações decorrentes do princípio da separação de poderes, entre o Administrativo e o Judicial, nos termos expressos no art. 71º/2 do Código de Processo, que determina que quando a emissão do acto pretendido envolva a formulação de valorações próprias do exercício da função administrativa (…) o tribunal não pode determinar o conteúdo do acto a praticar, mas deve explicitar as vinculações a observar (…) na emissão do acto devido. À limitação enunciada acresce outra, sem reflexo no texto do Código mas que se impõe por via do mesmo princípio, e que respeita aos poderes do tribunal no conhecimento e determinação dos pressupostos do acto devido, nos casos em que estes são questionados em juízo. A determinação dos pressupostos de facto do acto devido pelo tribunal está limitada pela natureza da actividade instrutória procedimental, pelo (in)cumprimento do ónus da prova no procedimento pelo interessado, nos casos limitados em que este tem relevância e pelo princípio da decisão prévia administrativa, nos termos do qual é à Administração que compete o conhecimento e decisão das pretensões que lhe são dirigidas e cuja competência que lhe foi determinada pela lei. Os limites enunciados não prejudicam a sindicabilidade, pelos tribunais, dos actos de recolha e valoração das provas pela Administração, que, nos casos em que configurem espaços de margem de livre decisão administrativa, são sindicáveis nos termos em que pode ser controlada a actividade autodeterminada da Administração, sem qualquer limitação quanto aos meios de prova.

The Theory of Interhybridity: Socio-political Dimensions and Migration Experiences of Post-communist Western Balkan States

The Western Balkans integration within the EU has started a legal process which is the rejection of former communist legal/political approaches and the transformation of former communist institutions. Indeed, the EU agenda has brought vertical/horizontal integration and Europeanization of national institutions (i.e. shifting power to the EU institutions and international authorities). At this point, it is very crucial to emphasize the fact that the Western Balkans as a whole region has currently an image that includes characteristics of both the Soviet socialism and the European democracy. The EU foreign policies and enlargement strategy for Western Balkans have significant effects on four core factors (i.e. Schengen visa regulations, remittances, asylum and migration as an aggregate process). The convergence/divergence of EU member states’ priorities for migration policies regulate and even shape directly the migration dynamics in migrant sender countries. From this standpoint, the research explores how main migration factors are influenced by political and judicial factors such as; rule of law and democracy score, the economic liberation score, political and human rights, civil society score and citizenship rights in Western Balkan countries. The proposal of interhybridity explores how the hybridization of state and non-state actors within home and host countries can solve labor migration-related problems. The economical and sociopolitical labor-migration model of Basu (2009) is overlapping with the multidimensional empirical framework of interhybridity. Indisputably, hybrid model (i.e. collaboration state and non-state actors) has a catalyst role in terms of balancing social problems and civil society needs. Paradigmatically, it is better to perceive the hybrid model as a combination of communicative and strategic action that means the reciprocal recognition within the model is precondition for significant functionality. This will shape social and industrial relations with moral meanings of communication.

La modernisation de Tunis : un urbanisme et une architecture d’État au miroir d’une anthologie de la percée dans la médina (1881-1987)

Cette thèse traite de quelques moments clés dans l’histoire urbaine et architecturale moderne de la ville de Tunis. Elle les aborde conjointement à la problématique du percement de son noyau historique : la médina, née d’un projet de modernisation urbaine lancé par les beys de Tunis à la fin du XIXe siècle, poursuivi par le protectorat français de 1881 à 1956, puis par le gouvernement indépendant de 1956 à 1987. Partant, la recherche est répartie sur trois temps avec, au centre, le projet de la percée dite de la Casbah adopté par le Président Bourguiba à la fin de 1959. Pour plusieurs raisons, ce moment est cité rapidement dans la littérature malgré son importance dans la compréhension du visage actuel de la capitale tunisienne. Pour le saisir, on a dû retourner aux premières tentatives de percement de la médina de Tunis par le colonisateur français en 1887. Puis, on s’est progressivement approché de l’ancêtre direct de la percée bourguibienne paru sur le Plan directeur de Tunis en 1948. De ce premier temps, on a mis en valeur les stratégies coloniales dans leur gestion du territoire et leur rapport au processus de valorisation/dévalorisation du patrimoine issu de la civilisation arabo-islamique. Le second temps, qui correspond au plan de décolonisation mené par l’État indépendant dès 1955, est marqué par le lancement d’un « concours international ouvert pour une étude d’aménagement de la ville de Tunis » organisé par le Secrétariat d’État aux travaux publics en collaboration avec l’Union internationale des architectes. L’étude de cet événement et du colloque qui l’a suivi a ôté le voile sur ses raisons d’être politico-économiques que dissimulaient les usuels soucis de l’hygiène, de la circulation et de l’embellissement du Grand Tunis. Pour appuyer davantage ces constats, un troisième et dernier temps a été dédié au chantier de Tunis au lendemain du concours. L’accent mis sur les lieux symboliques du pouvoir et le désir obsessif des autorités à se les approprier ont réduit ce chantier à une redistribution concertée des symboles de la souveraineté nationale dans le but de centraliser et de personnifier le pouvoir en place. Le présent travail se situe dans le cadre des études postcoloniales et projette un regard critique sur la décolonisation en rapport avec ce qu’on a taxé d’urbanisme d’État. Propulsé par une certaine perception de la modernité, cet urbanisme est indissociable d’une instrumentalisation politique qui met l’accent sur les questions identitaires et patrimoniales, insiste sur la rupture avec le passé et tend à écarter l’opinion publique des questions inhérentes à l’aménagement du territoire et à la sauvegarde de la mémoire collective. En procédant par une analyse contextuelle de faits historiques et une lecture typomorphologique de la percée de la Casbah, cette recherche attire l’attention sur l’ampleur de certaines décisions gouvernementales concernant l’aménagement de l’espace urbain et la conservation de l’héritage architectural à court, moyen et long termes. Elle renseigne aussi sur le rôle des collectivités, de l’élite et des professionnels dans la canalisation de ces décisions pour ou contre leur droit à la ville.

The EU's Group-to-Group Dialogue with the Southern Mediterranean and ASEAN – How much have they achieved? A Comparative Analysis. EU Centre Singapore Working Paper No, 18, December 2013

Four decades of the EU's group-to-group dialogues with the Southern Mediterranean grouping of countries and with ASEAN have produced different dynamics and outcomes, despite the EU’s common strategy to use economic soft power to achieve their goals for the partnerships. Diverging conditions in the two regions created inconsistency in the EU's application of the common approach. The EU's neighbourhood security concerns forced it to relax its political stand with their Southern Mediterranean partners. For ASEAN, geographical distance dilutes the EU’s security concerns it that region and has afforded the EU to be more ideological and assertive on democracy and human rights practices. These issues have provoked disagreements in EU-ASEAN dialogues, but both sides have also tried to remain pragmatic in order to achieve some progress in the partnership. In contrast, the protracted the Arab-Israeli conflict continues to hamper the Euro-Mediterranean dialogue, resulting in little progress. Social upheavals in the Southern Mediterranean also brought their partnership to a standstill. The EU's cooperation with former authoritarian regimes like Libya and Syria have only caused damage to its credibility in the Southern Mediterranean, and future Euro-Mediterranean dialogues are likely to be affected by it.

Ukraine: sovereign decentralisation or federalism without sovereignty? OSW Commentary No. 133, 18.04.2014

A key element of Russia’s policy towards the new government of Ukraine concerns demands for a constitutional reform that would transform the country from a unitary into a federal state in a way that would considerably privilege the eastern and southern regions. Such a change to Ukraine’s administrative system would enable Moscow to put pressure on Ukraine’s central government via the regions. In order to achieve its objectives, Russia has been pressuring Kyiv to establish a constitutional assembly in a form that would guarantee the endorsement of solutions dictated by Russia. In other words, Russia has been demanding, in what is practically an ultimatum, that Ukraine give up one of the fundamental sovereign rights of a state, the right to freely determine its system of government. Transforming Ukraine into a federal state is an unacceptable idea, primarily because the intention behind Russia’s demands is to undermine Ukraine’s sovereignty, both through the content of the proposed changes and the way in which they are to be implemented. However, keeping in place the current, centralist model of state governance is not a feasible alternative. Ukraine will have to grant its regions broad self-governance powers, including the power to hold local referendums, and to transfer a considerable portion of the prerogatives currently held by the state to the local self-governments, along with adequate financial resources. That is because decentralisation along these lines is the only way forward towards a modern democracy in Ukraine. Russia’s policy has forced Kyiv to undertake legislative work on constitutional reform as a matter of urgency, rather than waiting until a new parliament is elected in which the new, post-Maidan balance of political power will be reflected, as political logic would require. The first draft of the constitutional amendments (of which no details are known at this stage) is to be presented in mid-May, and is expected to come into force in early autumn. However, whether these plans can be put into practice depends on further developments in the eastern part of Ukraine, because (among other reasons) if a state of emergency is introduced, the constitutional amendment process will have to be suspended.

Patterns of civil society after authoritarianism: a comparison of Portugal and Spain, 1970s-2000s. CES Papers - Open Forum #17, 2013-2014

In this paper we argue that patterns of civil society in post-authoritarian democracies are the result of divergent pathways to democracy. Through a comparison of contemporary Portugal (social revolution) and Spain (reform), we show that revolutionary pathways to democracy have a positive impact on the self-organizing abilities of popular groups, thus also contributing to a higher quality of democracy. There are three mechanisms in social revolutionary processes that contribute to this. The first stems from the fact that the masses are the key actor in the revolutionary transformation process, with the power to shape (at least partially) the new rules and institutions of the emerging democratic regime. This results in greater legal recognition and institutional embeddedness between civil society organizations and the state, making it easier, in turn, for resources to be transferred to those organizations. Secondly, as a result of changes to the social and economic structure, revolutions engender more egalitarian societies. Likewise, citizens are given more resources and capacities for collective action. Finally, revolutions tend to crystalize a political culture between elites and the masses in which the principles of egalitarian participation and social change through the action of the people are accepted. This all leads to greater opportunities, resources and legitimacy for the civic action of the common people during the subsequent democratic regime.

Reasons withheld and insufficient reasoning as due process violations: two cases before the ECHR

Two very different cases decided by the European Court of Human Rights illustrate how the non-availability of sufficient reasons, for pre-trial judicial decisions in one case, and for a decision in a civil and administrative matter in the other, can lead to due process violations in terms of Articles 5 or 6 of the Convention of Human Rights and Fundamental Freedoms.
