    Das «operative» Konzept der Institution

    Get PDF
    Die Institution und die Gruppe werden in dieser Arbeit im Sinne der «operativen Gruppenkonzepte», fussend auf Pichon-RiviĂšre und seinen Nachfolgern (BlĂ©ger, Bauleo und andere argentinische Autoren), definiert. Anhand klinischer Beispiele von Interventionen in psychiatrisch-psychotherapeutischen und pĂ€dagogischen Einrichtungen illustrieren wir die Arbeitsweise und etwas von der Wirkung, soweit dies ohne begleitenden forschungstechnischen Apparat möglich ist. Dabei geht es um eine Theorie und Praxis, die die Gruppe zum Gegenstand der psychoanalytischen klinischen Forschung, Therapie und Didaktik macht. Zentral und fĂŒr die Methode kennzeichnend ist das Gewicht, das auf das Setting und dessen verschiedene konstituierenden Elemente, nĂ€mlich die Gruppenaufgabe, die Koordination und Beobachtung/Interpretation, sowie die in der psychoanalytischen Praxis gelĂ€ufigen Faktoren der PrĂ€senz der Mitglieder in geregelten rĂ€umlich-zeitlichen und ökonomischen und Rollen-VerhĂ€ltnissen gelegt wird. Wir berichten im Folgenden ĂŒber einige rezente Erfahrungen mit Mitarbeiter-Teams in klinischen und pĂ€dagogischen Einrichtungen

    Die operative Gruppe als Theorie und Methode reflexiv-gruppaler Professionalisierung im Angesicht von Krisen

    Get PDF
    In einem ersten Schritt wird – ausgehend vom Begriff der Krise – das Konzept der operativen Gruppe des argentinischen Psychoanalytikers Enrique PichĂłn-RiviĂšre entfaltet. Das Settingkonzept wird als wesentliches Werkzeug der gruppendynamischen Professionalisierung in Hinblick auf deren Kompetenz – mit Gruppen zu arbeiten – vorgestellt. Soziale Kompetenzen werden hauptsĂ€chlich im Gruppenkontext entwickelt und verĂ€ndert. Nicht selten fehlt es der Ausbildung von Lehrpersonen an der Vermittlung oder an Lehroptionen dieser spezifischen psychodynamischen Gruppenkompetenzen. (DIPF/Orig.)In a first step – starting from the concept of crisis – the concept of the operative group (Grupo Operativo) by the Argentine psychoanalyst Enrique PichĂłn-RiviĂšre is unfolded. The setting concept of the operative group is presented as an essential tool for the group dynamic professionalisation of teachers with regard to their competence – to work with groups. Social competences are mainly developed and changed in the group context. It is not uncommon for teacher training to lack the teaching or teaching options of these specific psychodynamic group competencies. (DIPF/Orig.

    Sjef Teuns und die Kinderanalyse: ein StĂŒck PSZ-Geschichte

    Get PDF
    Eine Darstellung mit reichlich Zitaten aus den BeitrĂ€gen zu einem Arbeitstag anlĂ€sslich von Teuns’ 80. Geburtstag im Oktober 2006 am Psychoanalytischen Seminar ZĂŒrich (PSZ) gibt Auskunft darĂŒber, wer Sjef Teuns ist und was er in ZĂŒrich zur Entwicklung der Ausbildung in Kinder- und Jugendlichen-Psychoanalyse beigetragen hat. Teuns ist ein hollĂ€ndischer Kinderpsychiater und Psychoanalytiker, der sich von Jugend auf fĂŒr die UnterdrĂŒckten und Traumatisierten eingesetzt hat und die Psychoanalyse als Forschungs- und Arbeitsinstrument eingesetzt und gelehrt hat. Im PSZ haben sich zahlreiche Analytiker, Sozialarbeiter und PĂ€dagogen bei Sjef Teuns in Babybeobachtung und Kinder- und Jugendlichen-Analyse und -Therapie ausbilden lassen. Teuns’ TĂ€tigkeit hat sich nachhaltig im PSZ (Ausbildungscurriculum in Kinder- und Jugendlichen-Psychotherapie) und in verschiedenen psychiatrischen und sozialpĂ€dagogischen Einrichtungen in ZĂŒrich und der Nord- und Ostschweiz ausgewirkt

    Clinical Study Monitoring the pH on Tooth Surfaces in Patients with and without Erosion

    Get PDF
    The aim of this study was to compare tooth surface pH after drinking orange juice or water in 39 patients with dental erosion and in 17 controls. The following investigations were carried out: measurement of pH values on selected tooth surfaces after ingestion of orange juice followed by ingestion of water (acid clearance), measurement of salivary flow rate and buffering capacity. Compared with the controls, patients with erosion showed significantly greater decreases in pH after drinking orange juice, and the pH stayed lower for a longer period of time (p < 0.05). Saliva parameters showed no significant differences between the two patient groups except for a lower buffering capacity at pH 5.5 in the erosion group

    Therapeutic options to prevent recurrence of an aggressive aneurysmatic bone cyst of the cervical spine of a 16 year old boy - a case report

    Get PDF
    The aneurysmatic bone cyst (ABC) is a benign primary bone tumour. If located in the cervical spine, its expansive growth and destructive behaviour may lead to instability and serious neurological impairment. We report a case of a 16-year-old boy with an aggressive ABC in the 7th cervical vertebra. Computertomographic and magnetic resonance imaging revealed the envelopment of the left 7th and 8th spinal nerve along with the anterior displacement of the left vertebral artery. The interdisciplinary surgical strategy consisted of a partially incomplete cyst resection, subtotal spondylectomy with posterior screw-and-rod fixation from C6-Th1, iliac crest bone grafting and anterior plating from C6-Th1. With regard to the high rate of recurrence after incomplete resection published in the recent literature, the patient was postoperatively treated by megavoltage radiotherapy with a total dose of 30Gy (daily dose of 1.8 Gy for 3 weeks). The clinical and radiographic follow-up showed complete recovery of all neurologic impairments and no signs of tumour recurrence at 3, 6 and 12 months after surgery. This case highlights diverse treatment regimens and shall outline the challenge and the problems of the interdisciplinary decision-making in adolescents presenting with ABC in high-demanding anatomical regions

    A novel function of the key nitrogen-fixation activator NifA in beta-rhizobia: Repression of bacterial auxin synthesis during symbiosis

    Rhizobia fix nitrogen within root nodules of host plants where nitrogenase expression is strictly controlled by its key regulator NifA. We recently discovered that in nodules infected by the beta-rhizobial strain Paraburkholderia phymatum STM815, NifA controls expression of two bacterial auxin synthesis genes. Both the iaaM and iaaH transcripts, as well as the metabolites indole-acetamide (IAM) and indole-3-acetic acid (IAA) showed increased abundance in nodules occupied by a nifA mutant compared to wild-type nodules. Here, we document the structural changes that a P. phymatum nifA mutant induces in common bean (Phaseolus vulgaris) nodules, eventually leading to hypernodulation. To investigate the role of the P. phymatum iaaMH genes during symbiosis, we monitored their expression in presence and absence of NifA over different stages of the symbiosis. The iaaMH genes were found to be under negative control of NifA in all symbiotic stages. While a P. phymatum iaaMH mutant produced the same number of nodules and nitrogenase activity as the wild-type strain, the nifA mutant produced more nodules than the wild-type that clustered into regularly-patterned root zones. Mutation of the iaaMH genes in a nifA mutant background reduced the presence of these nodule clusters on the root. We further show that the P. phymatum iaaMH genes are located in a region of the symbiotic plasmid with a significantly lower GC content and exhibit high similarity to two genes of the IAM pathway often used by bacterial phytopathogens to deploy IAA as a virulence factor. Overall, our data suggest that the increased abundance of rhizobial auxin in the non-fixing nifA mutant strain enables greater root infection rates and a role for bacterial auxin production in the control of early stage symbiotic interactions

    MHz Unidirectional Rotation of Molecular Rotary Motors

    Get PDF
    A combination of cryogenic UV-vis and CD spectroscopy and transient absorption spectroscopy at ambient temperature is used to study a new class of unidirectional rotary molecular motors. Stabilization of unstable intermediates is achieved below 95 K in propane solution for the structure with the fastest rotation rate, and below this temperature measurements on the rate limiting step in the rotation cycle can be performed to obtain activation parameters. The results are compared to measurements at ambient temperature using transient absorption spectroscopy, which show that behavior of these motors is similar over the full temperature range investigated, thereby allowing a maximum rotation rate of 3 MHz at room temperature under suitable irradiation conditions
