Der selektive Therapeut - Mythos oder RealitÀt?
Die vorliegende Diplomarbeit befasst sich mit dem Thema Selbstselektion auf Therapeutenseite, welches in engem Zusammenhang mit dem Bereich differenzieller Indikation in der Psychotherapie sowie dem Aspekt der Passung zwischen Therapeut und Klient steht.
Der theoretische Teil der Arbeit gliedert die angefĂŒhrten Themenbereiche in drei Hauptkapitel. Im Rahmen des empirischen Teils werden â im Anschluss an die Darstellung der wissenschaftlichen Arbeitsmethode â die aus den leitfadenorientierten Experteninterviews gewonnenen Ergebnisse mittels strukturierender Inhaltsanalyse aufbereitet. Basierend auf dieser Auswertung sowie in Anlehnung an die theoretische Auseinandersetzung werden im Zuge einer Interpretation die Interviewresultate dem Theorieteil gegenĂŒbergestellt. Die daraus resultierenden Erkenntnisse stellt das letzte Kapitel vor, wobei zudem weiterfĂŒhrende Ăberlegungen aufgezeigt werden.The present diploma-thesis deals with the issue of self-selection by the psychotherapist, which is associated with the topic differential indication in psychotherapy and also with the aspect of matching between therapist and client.
The theoretical part of this thesis is divided into the mentioned subject areas in the form of three main chapters. Within the empirical part, the results from the guideline-based interviews with experts will be â subsequent to the description of the scientific working method â edited using the texturing content analysis. Based on this evaluation as well as referring to the theoretical examination, the interview results will be linked with the theory part in the course of an interpretation. The resultant findings are presented in the last chapter, in which further considerations will be pointed out too
Momentum Imaging of Photofragments and Photoelectrons using Fast Ion Beams
Photofragment und Photoelektronen Spektroskopie an schnellen Ionen- Strahlen â Im Rahmen der vorliegenden Arbeit wurde eine Methode zur Fragmentations- Kanal spezifischen Detektion von Photoelektronen der photoneninduzierten Dissoziation von schnellen MolekĂŒl-Ionen Strahlen etabliert. HierfĂŒr wurde ein neuartiges Sattelpunkt Elektronen-Spektrometer zunĂ€chst zur Untersuchung der Photodetachment Dynamik an einem Strahl negativ geladener Oâ Ionen bei 532 nm in Betrieb genommen. Um alle Reaktionsprodukte der Photolyse von kleinenWasserclustern (H2O)nH+ (n †3) im WellenlĂ€ngenbereich von 13.5-40 nm zu erfassen, kam zusĂ€tzlich ein neu entwickeltes Detektionssystem fĂŒr schwere Ionen-Fragmente zum Einsatz, welches in Kombination mit dem Sattelpunkt Spektrometer zur Untersuchung der dissoziativen Photoionisation des Hydronium- (H3O+) und des Zundel- Ions (H5O2 +) eingesetzt wurde. Hierbei konnte nachgewiesen werden, dass im Falle von H3O+ drei dominierende Zerfalls-KanĂ€le ein binĂ€rer H2O+ + H+ und zwei Drei- Körper AufbrĂŒche OH+ +2H+, OH+ +H+ +H durch Ionisation eines AuĂen-Valenz Elektrons initiiert wird. Durch die erstmalig gemessenen Elektronen-Spektren konnte gezeigt werden, dass vorrangig die Ionisation des 3a1 Orbitals den binĂ€ren Kanal bedingt, wohingegen eine Vakanz im 1e Orbital zur Fragmentation in den Dreikörper- Kanal fĂŒhrt. Weiterhin wurde die Photolyse von H5O2 + studiert, wobei fĂŒnf dominante KanĂ€le identifiziert werden konnten, bei denen in einer GroĂzahl von Reaktionen das Hydronium-Ion selbst abgespalten wird. Das gemessene Elektronen-Signal zeigt auch hier, dass vorranging Vakanzen in den AuĂenorbitalen zur Dissoziation des MolekĂŒls fĂŒhren
Dilead(II) chromium(III) heptaÂfluoride
Single crystals of the title compound, Pb2CrF7, were obtained by solid-state reaction. The monoclinic structure is isotypic with Pb2RhF7 and is built up of CrF6
3â octaÂhedra isolated from each other, inserted in a fluorite-related matrix of PbF6 distorted octaÂhedra, and PbF8 square antiÂprisms sharing edges and corners. The seventh F atom is âindependentâ, connected only to three Pb atoms within FPb3 triangles, sharing an edge and building an almost planar Pb4F2 unit, so that the formula can alternatively be written as Pb2F(CrF6)
Dissociative recombination measurements of HCl+ using an ion storage ring
We have measured dissociative recombination of HCl+ with electrons using a
merged beams configuration at the heavy-ion storage ring TSR located at the Max
Planck Institute for Nuclear Physics in Heidelberg, Germany. We present the
measured absolute merged beams recombination rate coefficient for collision
energies from 0 to 4.5 eV. We have also developed a new method for deriving the
cross section from the measurements. Our approach does not suffer from
approximations made by previously used methods. The cross section was
transformed to a plasma rate coefficient for the electron temperature range
from T=10 to 5000 K. We show that the previously used HCl+ DR data
underestimate the plasma rate coefficient by a factor of 1.5 at T=10 K and
overestimate it by a factor of 3.0 at T=300 K. We also find that the new data
may partly explain existing discrepancies between observed abundances of
chlorine-bearing molecules and their astrochemical models.Comment: Accepted for publication in ApJ (July 7, 2013
Rapid detection of Salmonella in food and feed by coupling loop-mediated isothermal amplification with bioluminescent assay in real-time
Salmonella is among the most significant pathogens causing food and feed safety concerns. This study examined the rapid detection of Salmonella in various types of food and feed samples by coupling loop-mediated isothermal amplification (LAMP) with a novel reporter, bioluminescent assay in real-time (BART). Performance of the LAMP-BART assay was compared to a conventional LAMP and the commercially available 3M Molecular Detection Assay (MDA) Salmonella. The LAMP-BART assay was 100 % specific among 178 strains (151 Salmonella and 27 non-Salmonella) tested. The detection limits were 36 cells per reaction in pure culture and 104 to 106 CFU per 25 g in spiked food and feed samples without enrichment, which were comparable to those of the conventional LAMP and 3M MDA Salmonella but 5â10 min faster. Ground turkey showed a strong inhibition on 3M MDA Salmonella, requiring at least 108 CFU per 25 g for detection. The correlation between Salmonella cell numbers and LAMP-BART signals was high (R 2â=â0.941â0.962), suggesting good quantification capability. After 24 h enrichment, all three assays accurately detected 1 to 3 CFU per 25 g of Salmonella among five types of food (cantaloupe, ground beef, ground turkey, shell eggs, and tomato) and three types of feed (cattle feed, chicken feed, and dry dog food) examined. However, 101 CFU per 25 g was required for cattle feed when tested by 3M MDA Salmonella. The Salmonella LAMP-BART assay was rapid, specific, sensitive, quantitative, and robust. Upon further validation, it may become a valuable tool for routine screening of Salmonella in various types of food and feed samples.https://doi.org/10.1186/s12866-016-0730-
Exploring high-energy doubly excited states of NH by dissociative recombination of NH+
We have investigated electron capture by NH+ resulting in dissociative recombination (DR). The impact energies studied of ~4â12 eV extend over the range below the two lowest predicted NH+ dissociative states in the FranckâCondon (FC) region of the ion. Our focus has been on the final state populations of the resulting N and H atoms. The neutral DR fragments are detected downstream of a merged electron and ion beam interaction zone in the TSR storage ring, which is located at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. Transverse fragment distances were measured on a recently developed high count-rate imaging detector. The distance distributions enabled a detailed tracking of the final state populations as a function of the electron collision energy. These can be correlated with doubly excited neutral states in the FC region of the ion. At low electron energy of ~5 eV, the atomic product final levels are nitrogen Rydberg states together with ground-state hydrogen. In a small electron energy interval near 7 eV, a significant part of the final state population forms hydrogen Rydberg atoms with nitrogen atoms in the first excited () term, showing the effect of Rydberg doubly excited states below the predicted 2â2Î ionic potential. The distance distributions above ~10 eV are compatible with nitrogen Rydberg states correlating to the doubly excited Rydberg state manifold below the ionic 2â4ÎŁâ level

The system under study involves stochastics, state time-delay, parameter uncertainties, possible actuator failures and unknown nonlinear disturbances, which are often encountered in practice and the sources of instability. Our attention is focused on the design of linear state feedback memoryless controllers such that, for all admissible uncertainties as well as actuator failures occurring among a prespecified subset of actuators, the plant remains stochastically exponentially stable in mean square, independent of the time delay. Sufficient conditions are proposed to guarantee the desired robust reliable exponential stability despite possible actuator failures, which are in terms of the solutions to algebraic Riccati inequalities. An illustrative example is exploited to demonstrate the applicability of the proposed design approac
