Modernisierung in kleinen Schritten? Die Reformen der Parteiorganisation der British Conservative Party und der deutschen CDU im Vergleich

Seit den frühen und wichtigen Arbeiten von Maurice Duverger (1954) und Robert Michels (1962) besteht ein großes Forschungsinteresse an der Entwicklung von Parteiorganisationen und deren Wandel. Darin spiegeln sich die erheblichen Konsequenzen, die sich aus den jeweiligen Organisationsformen der politischen Parteien ergeben, wider.

The Front National:from systematic opposition to systemic integration?

For most of its existence, the Front National (FN) fitted the classic definition of the anti-system party, opposing the founding values, institutions and elites of the Fifth Republic. Now, under Marine Le Pen's leadership, it has embarked on a strategy to integrate to the regime it once defied. Does this strategy of normalisation bear scrutiny? Using a framework drawn from Giovanni Sartori and Robert Michels, this article asks whether the FN is a one-time anti-system party that is becoming mainstream, and also whether these simple oppositional categories are adequate for understanding ideological and policy evolution in the FN's case. Through an analysis of continuity and change in FN strategy and programmes, the article shows a party torn between anti-system differentiation and institutional adaptation. It may claim to have cast out its demons but has not undertaken the necessary moderation of its programme to substantiate that claim. The FN today is on no linear path of deradicalisation but exhibits a combination of consistent, diminished and increasing radicalism across different policy areas. Despite an upward dynamic and a hugely favourable context, it remains almost entirely excluded from power and far from the breakthrough required to become a party of government.

Surface characteristics and metazoa occurrence at ice station PS67/006-1 during POLARSTERN cruise ANT-XXII/2 (Nov 2004-Jan 2005)

The surface and sub-ice layer habitats and their metazoan fauna were studied on a drifting pack-ice floe in the western Weddell Sea from 29 November 2004 to 1 January 2005 during the "Ice Station POLarstern" (ISPOL). Flooding of the floe occurred at some places, and the establishment of surface layers with a brownish colour due to growing algae was observed at several sampling sites. The average surface-layer temperature, brine salinity and brine volume were -1.4 °C, 25.3 and 54%, respectively. The temperature-salinity relationship in the surface layer was seldom at equilibrium conditions. Chlorophyll a (Chl a) concentrations in the brine varied between 1.0 and 53.5 µg /L. Surface-layer thickness, salinity, Chl a concentration and copepod abundances were generally higher at the edge of the floe than in the inner part. The sympagic copepod species Drescheriella glacialis/racovitzai and Stephos longipes, with abundances ranging between 0 and 3830 ind/L (median: 2 ind/L) and 0 and 1293 ind/L (median: 4 ind/L), respectively, were the dominant members of the surface-layer meiofauna. Their populations consisted mainly of adults and early naupliar stages, which points to an active reproduction of these species within the surface layer. Other taxa found in the surface layer were undetermined turbellarians, the gastropod Tergipes antarcticus, and, for the first time, the ctenophore Callianira antarctica, and the amphipods Eusirus antarcticus and Eusirus tridentatus. During the course of our study, slight melting at the ice underside took place, releasing sympagic organisms to the water column. Chl a concentrations in the sub-ice water layer were very low (0.1-0.5 µg /L), except for 25 December when the Chl a concentration at 0 m depth increased to 2.3 µg /L. The most dominant sympagic copepod species found in the sub-ice layer was Ectinosoma sp., with abundances ranging between 1 and 599 ind/m**3 (median: 25 ind/m**3). Other sympagic copepod species occurring regularly in this habitat were D. glacialis/racovitzai, Diarthrodes cf. lilacinus, Idomene antarctica and S. longipes. All of these sympagic species were generally found in higher abundances at 0 m depth underneath the ice than at 5 m depth, in contrast to pelagic copepod species that occurred more frequently at 5 m depth. Niche separation and probable life-cycle strategies of dominant sympagic metazoans are discussed.

Michel Maffesoli y la razón sensible: una argumentación postmoderna

Se establecen algunas coordenadas de análisis para inscribir la obra de Michel Maffesoli, reconocido sociólogo francés, en el contexto de la reflexión postmoderna. Maffesoli, desde sus primeras obras, se ha interesado por construir una perspectiva en las ciencias sociales que vaya más allá del modernismo cartesiano y positivista. Su propuesta metodológica incorpora temáticas afines al pensamiento postmoderno, en particular, lo correspondiente a un nuevo concepto de razón y de conocimiento. Abstract There are some guidelines for inscribe the Michels Maffesioli writings in the postmodern context ; since his first works he has shown a great interest for build a theoretical perspective for social sciences that go beyond from the modernism and positivism cartesian thought. His method proposal incorporates close thematic areas with the posmodern thought, especially the themes related with a new concept of reason and knowledge.

Uma API criptográfica para aplicações embarcadas

This document presents GEmSysC, an unified cryptographic API for embedded systems. Software layers implementing this API can be built over existing libraries, allowing embedded software to access cryptographic functions in a consistent way that does not depend on the underlying library. The API complies to good practices for API design and good practices for embedded software development and took its inspiration from other cryptographic libraries and standards. The main inspiration for creating GEmSysC was the CMSIS-RTOS standard, which defines an unified API for embedded software in an implementation-independent way, but targets operating systems instead of cryptographic functions. GEmSysC is made of a generic core and attachable modules, one for each cryptographic algorithm. This document contains the specification of the core of GEmSysC and three of its modules: AES, RSA and SHA-256. GEmSysC was built targeting embedded systems, but this does not restrict its use only in such systems – after all, embedded systems are just very limited computing devices. As a proof of concept, two implementations of GEmSysC were made. One of them was built over wolfSSL, which is an open source library for embedded systems. The other was built over OpenSSL, which is open source and a de facto standard. Unlike wolfSSL, OpenSSL does not specifically target embedded systems. The implementation built over wolfSSL was evaluated in a Cortex- M3 processor with no operating system while the implementation built over OpenSSL was evaluated on a personal computer with Windows 10 operating system. This document displays test results showing GEmSysC to be simpler than other libraries in some aspects. These results have shown that both implementations incur in little overhead in computation time compared to the cryptographic libraries themselves. The overhead of the implementation has been measured for each cryptographic algorithm and is between around 0% and 0.17% for the implementation over wolfSSL and between 0.03% and 1.40% for the one over OpenSSL. This document also presents the memory costs for each implementation.

Mapping tissue inhomogeneity in acute myocarditis: a novel analytical approach to quantitative myocardial edema imaging by T2-mapping

BACKGROUND: The purpose of the present study was to investigate the diagnostic value of T2-mapping in acute myocarditis (ACM) and to define cut-off values for edema detection. METHODS: Cardiovascular magnetic resonance (CMR) data of 31 patients with ACM were retrospectively analyzed. 30 healthy volunteers (HV) served as a control. Additionally to the routine CMR protocol, T2-mapping data were acquired at 1.5 T using a breathhold Gradient-Spin-Echo T2-mapping sequence in six short axis slices. T2-maps were segmented according to the 16-segments AHA-model and segmental T2 values as well as the segmental pixel-standard deviation (SD) were analyzed. RESULTS: Mean differences of global myocardial T2 or pixel-SD between HV and ACM patients were only small, lying in the normal range of HV. In contrast, variation of segmental T2 values and pixel-SD was much larger in ACM patients compared to HV. In random forests and multiple logistic regression analyses, the combination of the highest segmental T2 value within each patient (maxT2) and the mean absolute deviation (MAD) of log-transformed pixel-SD (madSD) over all 16 segments within each patient proved to be the best discriminators between HV and ACM patients with an AUC of 0.85 in ROC-analysis. In classification trees, a combined cut-off of 0.22 for madSD and of 68 ms for maxT2 resulted in 83% specificity and 81% sensitivity for detection of ACM. CONCLUSIONS: The proposed cut-off values for maxT2 and madSD in the setting of ACM allow edema detection with high sensitivity and specificity and therefore have the potential to overcome the hurdles of T2-mapping for its integration into clinical routine.

Análisis de los cambios epigenéticos en la metilación del DNA inducidos por la diabetes y sus posibles mecanismos

Los cambios epigenéticos son responsables de la aparición de muchas patologías humanas y sus causas son debido a factores ambientales como genéticos. Se ha descrito en enfermedades crónicas como la Diabetes Mellitus tipo 2 (T2DM) que se caracteriza por los estados de hiperglucemia y el incremento en el estrés oxidativo que conlleva a complicaciones micro y macro vasculares, asociado a una desmetilación global del genoma. Nuestra hipótesis corresponde a que los órganos diana son afectados por las alteraciones como la metilación e hidroximetilación como consecuencia del estrés oxidativo que luego repercuten en la persistencia de la enfermedad. Métodos: A partir de sangre periférica se analizaron los cambios globales en la metilación del DNA que son afectados por el estado metabólico de 60 individuos (40 pacientes, 20 controles sanos). Por técnicas de cuantificación se compararon los resultados obtenidos con los de la expresión de las enzimas involucradas. Por último, se realizó un estudio de microarreglos de metilación del DNA y de expresión obtenidos de la base de datos GEO para así comparar los resultados con nuestros datos experimentales. Resultados: Los pacientes diabéticos con pobre control metabólico presentaron mayores niveles de metilación que el grupo control y no se encontró alteración en las enzimas involucradas en este proceso. Los resultados fueron concordantes con el estudio de microarreglos. Conclusión: Los estudios experimentales y de microarreglos demostraron que la metilación es tejido específico y que existe una mayor oxidación en pacientes. Por ello proponemos una vía alterna de desmetilación no enzimática, basada en la oxidación directa de los grupos metilos generados por los estados oxidativos característicos de esta enfermedad.
