Lessons for the EU from the Senkaku/Diaoyu Islands Crisis. IES Policy Brief Issue 2013/01 • February 2013

Summary. From April until October 2012, China witnessed a series of public protests against the Japanese purchase of the Senkaku/Diaoyu Islands. Besides providing further evidence of growing Chinese nationalism, this unrest is interesting for other reasons relevant to EU policy. The Beijing leadership, which is traditionally perceived as the only source of foreign policy decisions in China, faces a changing domestic constellation. Domestic opinion increasingly constrains Chinese foreign policy, and it becomes obvious that foreign policy decision-making in Beijing is not insulated from larger social developments. Even if foreign policy decisions in China are still made without direct input from civil society, the influence of social forces on Chinese foreign policies has to be taken seriously. The EU thus might want to reconsider its approach to China: as long as EU concerns about human rights are met with a rather uncompromising attitude by the Chinese political elites, Brussels should double its efforts to reach Chinese civil society.

Towards Explaining Anti-Foreign Violence in Germany. CES Germany & Europe Working Papers, No. 04.8 (Series 53), 1993

Gennany has recently witnessed a vast increase in anti-foreign violence. Assembling data from a wide variety of recent research, the paper addresses two basic questions: to what extent is the outburst of xenophobic attacks a German peculiarity? and what are the explanations for the mcreasing violence? An analysis of criminal statistics of various European countries and of comparative opinion polls in the European Community shows that Germany has indeed witnessed a growth of anti-foreign sentiment, and a level of violence that is conspicuous from a com­ parative perspective. Four possible determinants of this peculiarity of recent German history are discussed: (1) the growing ethnic and cultural heterogeneity due to the vast increase in immigration from non-European countries; (2) the increasing costs of foreigners' claims on the German welfare state; (3) the economic context of immigration; and (4) the transformation of national identity in the context of German unification. It is shown that neither the rate of immigration nor the position of foreigners in the German welfare state yields satisfactory explanations for the recent upsurge in violence, which only occurred after unification. The key for an explanation lies in a particu­lar macro-constellation that is characterized by the concurrence of a massive wave of immigration with an economic crisis, and with the ethnicization of German national identity in the context of unification. Anti-foreign sentiments do not automatically follow increases in immigration, but grow in a specific political climate to which the political elites actively contribute.

European Corporate Governance Reform and the German Party Paradox. CES Germany & Europe Working Papers, No. 03.1, 2003

This paper addresses the current discussion on links between party politics and production regimes. Why do German Social Democrats opt for more corporate governance liberalization than the CDU although, in terms of the distributional outcomes of such reforms, one would expect the situation to be reversed? I divide my analysis into three stages. First, I use the European Parliament’s crucial vote on the European takeover directive in July 2001 as a test case to show that the left-right dimension does indeed matter in corporate governance reform, beside cross-class and cross-party nation-based interests. In a second step, by analyzing the party positions in the main German corporate governance reforms in the 1990s, I show that the SPD and the CDU behave “paradoxically” in the sense that the SPD favored more corporate governance liberalization than the CDU, which protected the institutions of “Rhenish,” “organized” capitalism. This constellation occurred in the discussions on company disclosure, management accountability, the power of banks, network dissolution, and takeover regulation. Third, I offer two explanations for this paradoxical party behavior. The first explanation concerns the historical conversion of ideas. I show that trade unions and Social Democrats favored a high degree of capital organization in the Weimar Republic, but this ideological position was driven in new directions at two watersheds: one in the late 1940s, the other in the late 1950s. My second explanation lies in the importance of conflicts over managerial control, in which both employees and minority shareholders oppose managers, and in which increased shareholder power strengthens the position of works councils.

Automatic Fiscal Stabiliser: Make it happen! EPC Discussion Paper, 2 May 2016

The eurozone crisis triggered a whole new series of innovations in EU economic governance in order to make the Union more resilient for the next economic downswing. But one of the more persistent issues are the socio-economic divergences between member states, identified by the Five Presidents’ Report as a major problem in the functioning of the Economic and Monetary Union (EMU). Debates took place in recent years about automatic stabilisers, and more specifically about the possibility of introducing an unemployment insurance within the EMU. While the need for some form of fiscal risk-sharing has become a dominant view in expert circles, there has been much less progress among the main political parties and stakeholders. In this study, Regula Hess and László Andor analyse the political feasibility of the adoption of an automatic fiscal stabiliser (AFS) for the eurozone by evaluating actors’ positions towards three distinctive proposals: 1) cyclical shock insurance, 2) reinsurance, 3) a European basic unemployment insurance; they included an empirical case study of France and Germany as the most relevant players within the intergovernmental bargaining constellation. Although the authors realise the current political context makes the adoption of an AFS improbable, Hess and Andor encourage stakeholders to further pursue the discussion, as windows of opportunities can open at any time, and even give some suggestions on what the parameters of the most feasible proposal might be.

Wavering into Capitalism: The Politics of Sustenance in North Korea

In the 1990s, a catastrophic famine engrossed North Korea. The famine not only claimed thousands of innocent lives but also the social, economic and political principles which had governed the nation since its founding. This paper contends that the famine engendered the rise of a rights-consciousness among North Korean working class citizens. In particular, the famine compelled the rise of bottom-up markets among common North Koreans, as the state failed to uphold its end of caloric compact, which then radically shifted the moral frameworks of the people. The nature in which these frameworks shifted is the focus of my paper. Chronicling the market protests which transpired during the late 2000s, this paper unveils the emergence of a novel constellation of power between the private citizen and the state in consequence of the markets engendering a rights-consciousness.

Genetic algorithms with applications in wireless communications

Genetic algorithms (GAs) are known to locate the global optimal solution provided sufficient population and/or generation is used. Practically, a near-optimal satisfactory result can be found by Gas with a limited number of generations. In wireless communications, the exhaustive searching approach is widely applied to many techniques, such as maximum likelihood decoding (MLD) and distance spectrum (DS) techniques. The complexity of the exhaustive searching approach in the MLD or the DS technique is exponential in the number of transmit antennas and the size of the signal constellation for the multiple-input multiple-output (MIMO) communication systems. If a large number of antennas and a large size of signal constellations, e.g. PSK and QAM, are employed in the MIMO systems, the exhaustive searching approach becomes impractical and time consuming. In this paper, the GAs are applied to the MLD and DS techniques to provide a near-optimal performance with a reduced computational complexity for the MIMO systems. Two different GA-based efficient searching approaches are proposed for the MLD and DS techniques, respectively. The first proposed approach is based on a GA with sharing function method, which is employed to locate the multiple solutions of the distance spectrum for the Space-time Trellis Coded Orthogonal Frequency Division Multiplexing (STTC-OFDM) systems. The second approach is the GA-based MLD that attempts to find the closest point to the transmitted signal. The proposed approach can return a satisfactory result with a good initial signal vector provided to the GA. Through simulation results, it is shown that the proposed GA-based efficient searching approaches can achieve near-optimal performance, but with a lower searching complexity comparing with the original MLD and DS techniques for the MIMO systems.

Antibacterial dosing in intensive care: Pharmacokinetics, degree of disease and pharmacodynamics of sepsis

Treatment of sepsis remains a significant challenge with persisting high mortality and morbidity. Early and appropriate antibacterial therapy remains an important intervention for such patients. To optimise antibacterial therapy, the clinician must possess knowledge of the pharmacokinetic and pharmacodynamic properties of commonly used antibacterials and how these parameters may be affected by the constellation of pathophysiological changes occurring during sepsis. Sepsis, and the treatment thereof, increases renal preload and, via capillary permeability, leads to 'third-spacing', both resulting in higher antibacterial clearances. Alternatively, sepsis can induce multiple organ dysfunction, including renal and/or hepatic dysfunction, causing a decrease in antibacterial clearance. Aminoglycosides are concentration-dependent antibacterials and they display an increased volume of distribution (V-d) in sepsis, resulting in decreased peak serum concentrations. Reduced clearance from renal dysfunction would increase the likelihood of toxicity. Individualised dosing using extended interval dosing, which maximises the peak serum drug concentration (C-max)/minimum inhibitory concentration ratio is recommended. beta-Lactams and carbapenems are time-dependent antibacterials. An increase in Vd and renal clearance will require increased dosing or administration by continuous infusion. If renal impairment occurs a corresponding dose reduction may be required. Vancomycin displays predominantly time-dependent pharmacodynamic properties and probably requires higher than conventionally recommended doses because of an increased V-d and clearance during sepsis without organ dysfunction. However, optimal dosing regimens remain unresolved. The poor penetration of vancomycin into solid organs may require alternative therapies when sepsis involves solid organs (e.g. lung). Ciprofloxacin displays largely concentration-dependent kill characteristics, but also exerts some time-dependent effects. The V-d of ciprofloxacin is not altered with fluid shifts or over time, and thus no alterations of standard doses are required unless renal dysfunction occurs. In order to optimise antibacterial regimens in patients with sepsis, the pathophysiological effects of systemic inflammatory response syndrome need consideration, in conjunction with knowledge of the different kill characteristics of the various antibacterial classes. In conclusion, certain antibacterials can have a very high V-d, therefore leading to a low C-max and if a high peak is needed, then this would lead to underdosing. The Vd of certain antibacterials, namely aminoglycosides and vancomycin, changes over time, which means dosing may need to be altered over time. Some patients with serum creatinine values within the normal range can have very high drug clearances, thereby producing low serum drug levels and again leading to underdosing.

Physical and MAC layer techniques for next generation satellite communications

In this thesis, we consider four different scenarios of interest in modern satellite communications. For each scenario, we will propose the use of advanced solutions aimed at increasing the spectral efficiency of the communication links. First, we will investigate the optimization of the current standard for digital video broadcasting. We will increase the symbol rate of the signal and determine the optimal signal bandwidth. We will apply the time packing technique and propose a specifically design constellation. We will then compare some receiver architectures with different performance and complexity. The second scenario still addresses broadcast transmissions, but in a network composed of two satellites. We will compare three alternative transceiver strategies, namely, signals completely overlapped in frequency, frequency division multiplexing, and the Alamouti space-time block code, and, for each technique, we will derive theoretical results on the achievable rates. We will also evaluate the performance of said techniques in three different channel models. The third scenario deals with the application of multiuser detection in multibeam satellite systems. We will analyze a case in which the users are near the edge of the coverage area and, hence, they experience a high level of interference from adjacent cells. Also in this case, three different approaches will be compared. A classical approach in which each beam carries information for a user, a cooperative solution based on time division multiplexing, and the Alamouti scheme. The information theoretical analysis will be followed by the study of practical coded schemes. We will show that the theoretical bounds can be approached by a properly designed code or bit mapping. Finally, we will consider an Earth observation scenario, in which data is generated on the satellite and then transmitted to the ground. We will study two channel models, taking into account one or two transmit antennas, and apply techniques such as time and frequency packing, signal predistortion, multiuser detection and the Alamouti scheme.

SEXUALIDADE: INQUIETAÇÕES E NECESSIDADES DO ADOLESCENTE CRISTÃO SOB O ENFOQUE OPERATIVO DE PICHON-RIVIÈRE

O presente estudo visa investigar a sexualidade na adolescência em suas inquietações e necessidades por meio do método de investigação clínica de abordagem psicanalítica de Enrique Pichon-Rivière, para se obter uma compreensão da psicodinâmica do grupo de adolescentes com enfoque operativo. Os objetivos são: 1. Levantamento do que os adolescentes pensam sobre sexualidade; 2. Discutir os principais conflitos vividos pelos adolescentes com relação à sexualidade e; 3. Analisar as formas de manifestações culturais dos adolescentes sobre a sexualidade. O procedimento inicial foi um levantamento bibliográfico sobre os temas: sexualidade, repressão, fantasias inconscientes e grupo com enfoque operativo. Os adolescentes de uma comunidade religiosa da metrópole de São Paulo foram os participantes. Realizaram-se 12 encontros grupais com enfoque operativo, utilizando-se a teoria e técnica dos grupos operativos de Pichon-Rivière. Houve um roteiro temático, que forneceram os conteúdos para cada encontro. Os temas revelaram sentimentos e reações emocionais dos adolescentes sobre sexualidade, dificuldades e facilidades encontradas em relação às manifestações culturais e a existência de conflitos (medos e desejos inconscientes) vividos pelos adolescentes. As análises dos resultados levaram a considerações que direcionam a duas vertentes: a) As inquietações representadas por dúvidas, sentimentos de perda, informações consistentes e medos; b) As necessidades estavam representadas pela lealdade, confiança, interação social, acolhimento (continência) e valores do grupo primário de referência. Conclui-se que o adolescente apresenta forte sentimento de desconfiança, caracterizando uma constelação de fantasias na qual predomina a persecutoriedade; esse adolescente está sempre preocupado com o externo, com o que os outros estão pensando

Alternative Emanzipationsvorstellungen in der DDR unter Honecker (1971-1990):ein Diskussionsbeitrag zur Rollen der Frau

Over the last twenty years the situation of women in the German Democratic Republic has been the subject of a considerable number of studies. The approach has generally been of a sociological or socio-political nature. In this thesis I propose to go one step further by examining the information that may be gained from literary sources. In a state where the media are subject to censorship, and thus controlled, one can refer to literature as an acknowledged source of inside information. Literary works often provide a forum for the formulation and discussion of ideas, which could not be aired elsewhere. Chapter 1 shows why literature, which had always been allocated a special role by the GDR's leading party, the SED, may be regarded as a reliable indicator of everyday life in that country. In this thesis I compare the findings of an analysis of women's literature with sociological data on the one hand and the portrayal of the "ideal" women in GDR media and official writings on the other. The thesis takes an interdisciplinary approach and draws on sources in political, legal, sociological, and cultural fields alike. This constellation of sources allows me to show that the views that female writers expressed in their works frequently coincide with sociological findings. Both of these sources were frequently found to be at odds with statements made in official writings and the media. Such insights could not have been provided by a study conducted from within one discipline.

Consumer brand equity : a model for the measurement, analysis and evaluation of consumer perceived value

The topic of my research is consumer brand equity (CBE). My thesis is that the success or otherwise of a brand is better viewed from the consumers’ perspective. I specifically focus on consumers as a unique group of stakeholders whose involvement with brands is crucial to the overall success of branding strategy. To this end, this research examines the constellation of ideas on brand equity that have hitherto been offered by various scholars. Through a systematic integration of the concepts and practices identified but these scholars (concepts and practices such as: competitiveness, consumer searching, consumer behaviour, brand image, brand relevance, consumer perceived value, etc.), this research identifies CBE as a construct that is shaped, directed and made valuable by the beliefs, attitudes and the subjective preferences of consumers. This is done by examining the criteria on the basis of which the consumers evaluate brands and make brand purchase decisions. Understanding the criteria by which consumers evaluate brands is crucial for several reasons. First, as the basis upon which consumers select brands changes with consumption norms and technology, understanding the consumer choice process will help in formulating branding strategy. Secondly, an understanding of these criteria will help in formulating a creative and innovative agenda for ‘new brand’ propositions. Thirdly, it will also influence firms’ ability to simulate and mould the plasticity of demand for existing brands. In examining these three issues, this thesis presents a comprehensive account of CBE. This is because the first issue raised in the preceding paragraph deals with the content of CBE. The second issue addresses the problem of how to develop a reliable and valid measuring instrument for CBE. The third issue examines the structural and statistical relationships between the factors of CBE and the consequences of CBE on consumer perceived value (CPV). Using LISREL-SIMPLIS 8.30, the study finds direct and significant influential links between consumer brand equity and consumer value perception.

From therapeutic to political education: the centrality of affective sensibility in critical pedagogy

While the need for humanising education is pressing in neoliberal societies, the conditions for its possibility in formal institutions have become particularly cramped. A constellation of factors – the strength of neoliberal ideologies, the corporatisation of universities, the conflation of human freedom with consumer satisfaction, and a wider crisis of hope in the possibility or desirability of social change – make it difficult to apply classical theories of subject-transformation to new work in critical pedagogy. In particular, the growth of interest in pedagogies of comfort (as illustrated in certain forms of ‘therapeutic’ education and concerns about student ‘satisfaction’) and resistance to critical pedagogies suggest that subjectivty has become a primary site of political struggle in education. However, it can no longer be assumed that educators can (or should) liberate students’ repressed desires for ‘humanisation’ by politicising curricula, pedagogy or institutions. Rather, we must work to understand the new meanings and affective conditions of critical subjectivity itself. Bringing critical theories of subject transformation together with new work on ‘pedagogies of discomfort’, I suggest we can create new ways of opening up possibilities for critical education that respond to neoliberal subjectivities without corresponding to or affirming them.

Near-ML detection for MDL-impaired few-mode fiber transmission

Few-mode fiber transmission systems are typically impaired by mode-dependent loss (MDL). In an MDL-impaired link, maximum-likelihood (ML) detection yields a significant advantage in system performance compared to linear equalizers, such as zero-forcing and minimum-mean square error equalizers. However, the computational effort of the ML detection increases exponentially with the number of modes and the cardinality of the constellation. We present two methods that allow for near-ML performance without being afflicted with the enormous computational complexity of ML detection: improved reduced-search ML detection and sphere decoding. Both algorithms are tested regarding their performance and computational complexity in simulations of three and six spatial modes with QPSK and 16QAM constellations.

40-Gbaud 16-QAM transmitter using tandem IQ modulators with binary driving electronic signals

We propose a novel 16-quadrature amplitude modulation (QAM) transmitter based on two cascaded IQ modulators driven by four separate binary electrical signals. The proposed 16-QAM transmitter features scalable configuration and stable performance with simple bias-control. Generation of 16-QAM signals at 40 Gbaud is experimentally demonstrated for the first time and visualized with a high speed constellation analyzer. The proposed modulator is also compared to two other schemes. We investigate the modulator bandwidth requirements and tolerance to accumulated chromatic dispersion through numerical simulations, and the minimum theoretical insertion attenuation is calculated analytically.
