The force of the sign. Terrorism as a symbolic phenomenon

Seit der radikalen Änderung der weltpolitischen Lage durch das Selbstmordattentat islamistischer Terroristen auf die Supermacht U.S.A. am 11.9.01 versucht die Weltöffentlichkeit, dem Phänomen des Terrorismus durch die verschiedensten Erklärungsstrategien Herr zu werden. Man führt den Kampf der Kulturen oder Religionen an, verweist auf die Ausbeutung der Peripherie des kapitalistischen Weltsystems durch den Hegemon U.S.A. oder pathologisiert bzw. dämonisiert die Taten der Terroristen. Uns scheinen diese Erklärungsstrategien den Machtkonstellationen der postmodernen Gesellschaften nicht gerecht zu werden, da sie ein zentrales soziales Phänomen der vergangenen Jahrzehnte nicht beachten: das Unbehagen an der pluralistischen Gesellschaft und der konsensuell-repräsentativen Demokratie. Um dieses Unbehagen angemessen beschreiben zu können, wollen wir uns ihm aus einer zeichentheoretischen Perspektive nähern, die soziale Formationen nicht durch (kooperative) Arbeit determiniert sieht, sondern durch die Instanz des Codes. Für Jean Baudrillard ist die Wahl des Ziels der beiden Türme bedeutend, die sich wechselseitig reflektieren und das System nach allen Seiten hin abschließen. Mit ihnen wurde das neuralgische Zentrum des Systems getroffen, das sich auf einem binären Code gründet. Die Twintowers bedeuteten nicht nur das Ende jedweder originalen Referenz, sondern auch den Abschluss des Bezeichneten durch die Wiederholung des Zeichens. Der Code führt eine symbolische Verteilung der gesellschaftlichen Körper durch und zielt auf eine möglichst genaue Übereinstimmung der Gemeinschaft mit sich selbst gemäß eines arithmetischen und geometrischen Kalküls. Die integrative Kraft dieses auf dem Identitätsprinzip basierenden Systems scheint immer häufiger nicht mehr in der Lage zu sein, das negative Potential antagonistischer Strategien binden zu können, die in Form von zivilem Ungehorsam, Politik von Minoritäten oder terroristischen Akten die symbolische Ordnung der westlichen Gesellschaften unterhöhlen. In diesem Tagungsband diskutieren wir das Ausmaß der Krise der konsensuellen Demokratie und ihrer Institutionen. Die Aufsätze behandeln folgende Themen: • Die Krise der pluralistischen Gesellschaft: Wie verständlich ist das kulturelle, politische und religiöse Unbehagen am westlichen Wertekanon? • Die Funktion der Medien in der konsensuellen Demokratie; die gesellschaftliche Wirkung der medialen Reproduktion terroristischer Akte; das Bild des Terrorismus in der Populärkultur • Ästhetischer Terror: Die Vernichtung von Sinn und Bedeutung in der zeitgenössischen Kunst und Kunsttheorie • Die politische Logik des Terrorismus (Ziele, Bedingungen u. Legitimität des Terrorismus in Abgrenzung zu alternativen politischen Ausdrucksformen wie z.B. dem zivilen Ungehorsam; die Bedeutung des terroristischen Opfertodes) • Geschichte des Terrorismus (speziell der Terrorismus der RAF) • Terror als irrationale Gewalt (der ontologische Status des Terrorismus)Since the radical changes in international politics caused by the suicide attacks on the USA by Islamic terrorists on the 11th of September in 2001, the world public tries to grasp the phenomenon of „Terrorism“ through different explanatory strategies. These include referring to the clash of cultures and of religions, to the exploitation of the periphery by the capitalist system incarnated by the USA, or pathologizing as well as demonizing the deeds of the terrorists. All these explanatory attempts do not seem to do justice to the actual constellations of power in postmodern societies, because they do not take a widespread social phenomenon of the past decades in consideration: the discomfort with the pluralistic society and with the concurrent-representative democracy. In order to describe this discomfort adequately we would like to approach the phenomenon from a semiotic perspective which does not consider social formations as determined by cooperative work but rather by the authority of the code. For Jean Baudrillard the target was meaningful since the two towers not only reflect each other but also completely close the system. With them the neuralgic center which is based upon the binary code was severely hit. The twin towers not only meant the end of every original reference but also the completion of the signified by the reduplication of the sign. The code conducts a symbolic distribution of the social bodies and aims at an as accurate as possible identification of the community with itself corresponding to an arithmetic and geometric calculus. The system which is based upon the principle of identity does not seem to have the ability to integrate antagonist energies properly. So these antagonist powers undermine the symbolic order of western societies in terms of civil disobedience, politics of minorities or terroristic acts. In this conference transcript we discuss the degree of crisis of consensual democracy and ist institutions. The essays cover the following topics: • The crisis of the pluralistic society: How comprehensible and justified is the cultural, political, and religious discomfort with western values? • The function of mass media in democratic systems: What is the impact of the reproduction of terrorist acts on society? How does popular culture deal with terrorism? • Aesthetic terror: the destruction of sense and meaning in contemporary arts and art theory • The political logic of terrorism (aims, legitimacy of terrorism as opposed to other forms of opposition like civil disobedience; the meaning of the terrorist self-sacrifice death) • History of terrorism (e.g. The German terrorism of the RAF) • Terrorism as an irrational power (ontological status of terrorism

Significance of growth differentiation factor 15 in chronic HCV patients

Background and objective: Hepatitis C virus is the most common cause of chronic liver disease in Egypt. This work aims to assess the use of the simple and noninvasive biomarker Serum Growth differentiation Factor 15 (GDF-15), along with Alpha Fetoprotein (AFP) and Ferritin for the diagnosis of advanced liver disease in chronic hepatitis C patients. Subjects and methods: This study was conducted on 60 patients, who were recruited from the National Liver and Tropical Diseases Institute, Cairo, Egypt, who were suffering from early & advanced liver cirrhosis and chronic active hepatitis. Twenty cases of healthy subjects served as controls. Serum (GDF-15), (AFP), Ferritin and Hepatitis markers were measured by ELISA method. Measurement of different liver enzyme activity was done by the kinetic methods. Results: Data analysis revealed significant increase in serum levels of GDF15 in patients with Hepatocellular carcinoma (HCC) and Liver Cirrhosis (LC) compared to the healthy subjects. These results were parallel to those of serum levels of AFP, which also demonstrated significant increase in all patients groups as compared to normal control. A moderate increase in the GDF15 level was detected in the patients with chronic hepatitis C (CHC) compared to normal healthy subjects. Conclusion: This study demonstrated that GDF15 and AFP detection can help in the diagnosis and prediction of complications associated with CHC including liver cirrhosis and HCC. Also GDF15 can be used as a satisfactory serum marker of HCC and LC

Inheritance of Schistosoma mansoni infection incompatibility in Biomphalaria alexandrina snails

In this study, we looked at the inheritance of susceptibility and resistance to Schistosoma mansoni infection in the first generation of crossbred Biomphalaria alexandrina snails. Our ultimate goal is to use such information to develop a biological method of controlling schistosomiasis. We infected laboratory-bred snails with S. mansoni miracidia and examined cercarial shedding to determine susceptibility and resistance. Five parental groups were used: Group I contained 30 susceptible snails, Group II contained 30 resistant snails, Group III contained 15 susceptible and 15 resistant snails, Group IV contained 27 susceptible and three resistant snails and Group V contained three susceptible and 27 resistant snails. The percentage of resistant snails in the resulting progeny varied according to the ratio of susceptible and resistant parents per group; they are 7%, 100%, 68%, 45% and 97% from Groups I, II, III, IV and V, respectively. On increasing the percentage of resistant parent snails, the percentage of resistant progeny increased, while cercarial production in their susceptible progeny decreased
