    Nonverbale Synchronie und Musik-Erleben im klassischen Konzert

    No full text
    Die Praxis der Musikrezeption im Rahmen klassischer Konzerte ist von restriktiven Verhaltenskonventionen geprägt. Aktuelle kognitionswissenschaftliche und philosophische Ansätze, welche Musik-Erleben als verkörpert oder als über mehrere Individuen verteilt konzeptualisieren, scheinen daher für die Erklärung des Musik-Erlebens in klassischen Konzerten weniger geeignet. Vor diesem Hintergrund untersuchte die vorliegende explorative Studie das Auftreten koordinierter Körperbewegungen als nonverbale Synchronie im Rahmen eines klassischen Konzertes und den Zusammenhang zwischen den Synchronien innerhalb des Publikums und Aspekten des subjektiven Musik-Erlebens. Im Rahmen eines Forschungskonzerts wurden 22 Teilnehmern verschiedene Kammermusikwerke präsentiert, sowie dabei Selbstauskünfte zu Aspekten des Musik-Erlebens erhoben und Körperbewegungen mit drei stationären Kameras erfasst. Nonverbale Synchronie, als Indikator für koordinierte Körperbewegungen, wurde über die Korrelation von Bewegungsenergie-Zeitreihen ermittelt. Die Bewegungsenergie wurde als Anzahl der sich ändernden Pixel aufeinanderfolgender Frames operationalisiert. Es zeigte sich stark ausgeprägte Synchronie zwischen den Musikern sowie eine Synchronie kleiner bis mittlerer Effektstärke innerhalb des Publikums. Zwischen den Musikern und dem Publikum konnte hingegen keine Synchronie festgestellt werden. In Bezug auf das Verhältnis von Synchronie innerhalb des Publikums und dem subjektiven Musik-Erleben zeigten sich signifikante negative Zusammenhänge zwischen dem Gefühl der Verbundenheit mit den Musikern, dem Grad der Absorption und der Synchronisierung innerhalb des Publikums. Dies lässt sich dahingehend interpretieren, dass bei einem stärkeren Fokus der Aufmerksamkeit und des Erlebens auf das Bühnengeschehen die Synchronisierung mit den anderen Mitgliedern des Publikums abnimmt. Die Ergebnisse dieser Studie stehen im Einklang mit Theorien zum verkörperten Musik-Erleben, sie stützen jedoch Ansätze nicht, die darunter die Nachahmung der klangproduzierenden Bewegungen der Musiker verstehen. Ebenso stehen die Befunde nicht in Einklang mit Ansätzen zum verteilten Musik-Erleben. Abschließend werden die Ergebnisse hinsichtlich ihrer musikpraktischen Relevanz bezüglich einer Diversifizierung klassischer Konzerte diskutiert

    Background: Early readmissions following hospital discharge for heart failure (HF) remain a major concern. Among the various strategies designed to reduce readmissions, home evaluations have been observed to have a favorable impact. We assessed the feasibility of integrating community paramedics into the outpatient management of HF patients. Methods: Selected paramedics completed an educational HF curriculum. These Mobile Integrated Health Paramedics (MIHP) performed scheduled home visits 2- and 15-days post-discharge for patients with Stage C HF (Phase I) and patients with Stage D HF (Phase II). Facilitated by a Call Center, a process was created for performing urgent MIHP house calls within 60 minutes of a medical provider’s request. A HF specialist, with an on-call emergency department command physician, could order an intravenous diuretic during home visits. During each phase of the study the incidence of 30-day HF readmissions, 30-day all-cause readmissions, emergency room evaluations, unplanned office encounters, as well as any adverse events were prospectively documented. Results: Collaborative relationships between our hospital network and local EMS organizations were created. There were 82 MIHP home visits. Eight patients received urgent home evaluations within 60 minutes post-request, 1 requiring transport to an ED. The incidence of all-cause 30-day readmissions in 20 Stage C and 20 Stage D patients was 15% and 40%, respectively. There were no adverse events attributable to the MIHP house calls. Conclusions: It is feasible to integrate MIHPs into the outpatient management of HF. Signals of effectiveness for reducing early readmissions were observed. Obstacles to creating an effective paramedic “House Calls” program were identified. A randomized trial is required to assess the value of this care process and its impact on early readmissions in patients with Stage C and Stage D HF

    Interaction patterns of methoprene-tolerant and germ cell-expressed Drosophila JH receptors suggest significant differences in their functioning

    Methoprene-tolerant (Met) and germ cell-expressed (Gce) proteins were shown to be juvenile hormone (JH) receptors of Drosophila melanogaster with partially redundant functions. We raised the question of where the functional differentiation of paralogs comes from. Therefore, we tested Met and Gce interaction patterns with selected partners. In this study, we showed the ability of Gce and its C-terminus (GceC) to interact with 14-3-3 in the absence of JH. In contrast, Met or Met C-terminus (MetC) interactions with 14-3-3 were not observed. We also performed a detailed structural analysis of Met/Gce interactions with the nuclear receptor fushi tarazu factor-1 (Ftz-F1) ligand-binding domain. We showed that GceC comprising an Ftz-F1-binding site and full-length protein interacts with Ftz-F1. In contrast to Gce, only MetC (not full-length Met) can interact with Ftz-F1 in the absence of JH. We propose that the described differences result from the distinct tertiary structure and accessibility of binding sites in the full-length Met/Gce. Moreover, we hypothesize that each interacting partner can force disordered MetC and GceC to change the structure in a partner-specific manner. The observed interactions seem to determine the subcellular localization of Met/Gce by forcing their translocation between the nucleus and the cytoplasm, which may affect the activity of the proteins. The presented differences between Met and Gce can be crucial for their functional differentiation during D. melanogaster development and indicate Gce as a more universal and more active paralog. It is consistent with the theory indicating gce as an ancestor gene

    Bridging the gap between global models and full fluid models : a fast 1D semi-analytical fluid model for electronegative plasmas

    Get PDF
    Analytical and numerical models allow investigation of complicated discharge phenomena and the interplay that makes plasmas such a complex environment. Global models are quick to implement and can have almost negligible computation cost, but provide only bulk or spatially averaged values. Full fluid models take longer to develop, and can take days to solve, but provide accurate spatio-temporal profiles of the whole plasma. The work presented here details a different type of model, analytically similar to fluid models, but computationally closer to a global model, and able to give spatially resolved solutions for the challenging environment of electronegative plasmas. Included are non-isothermal electrons, gas heating, and coupled neutral dynamics. Solutions are reached in seconds to minutes, and spatial profiles are given for densities, fluxes, and temperatures. This allows the semi-analytical model to fill the gap that exists between global and full fluid models, extending the tools available to researchers. The semi-analytical model can perform broad parameter sweeps that are not practical with more computationally expensive models, as well as exposing non-trivial trends that global models cannot capture. Examples are given for a low pressure oxygen CCP. Excellent agreement is shown with a full fluid model, and comparisons are drawn with the corresponding global model

    2013 Review and Update of the Genetic Counseling Practice Based Competencies by a Task Force of the Accreditation Council for Genetic Counseling

    Full text link
    The first practice based competencies (PBCs) for the field of genetic counseling were adopted by the American Board of Genetic Counseling (ABGC), 1996. Since that time, there has been significant growth in established and new work settings (clinical and non‐clinical) and changes in service delivery models and the roles of genetic counselors. These changes prompted the ABGC to appoint a PBC Task Force in 2011 to review the PBCs with respect to their current relevance and to revise and update them as necessary. There are four domains in the revised PBCs: (I) Genetics Expertise and Analysis (II) Interpersonal, Psychosocial and Counseling Skills (III) Education and (IV) Professional Development and Practice. There are 22 competencies, each clarified with learning objectives or samples of activities and skills; a glossary is included. New competencies were added that address genomics, genetic testing and genetic counselors’ roles in risk assessment, education, supervision, conducting research and presenting research options to patients. With PBCs serving as the pre‐defined abilities or outcomes of training, graduating genetic counselors will be well prepared to enter the field with a minimum level of skills and abilities. A description of the Task Force’s work, key changes and the 2013 PBCs are presented herein.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/147172/1/jgc40868.pd

    Background: High dose oral thiamine may have a role in treating diabetes, heart failure, and hypermetabolic states. The purpose of this study was to determine the pharmacokinetic profile of oral thiamine hydrochloride at 100 mg, 500 mg and 1500 mg doses in healthy subjects. Methods: This was a randomized, double-blind, single-dose, 4-way crossover study. Pharmacokinetic measures were calculated. Results: The AUC010hrAUC_{0-10 hr} and CmaxC_{max} values increased nonlinearly between 100 mg and 1500 mg. The slope of the AUC010hrAUC_{0-10 hr} vs dose, as well as the CmaxC_{max} vs dose, plots are steepest at the lowest thiamine doses. Conclusion: Our study demonstrates that high blood levels of thiamine can be achieved rapidly with oral thiamine hydrochloride. Thiamine is absorbed by both an active and nonsaturable passive process

    The present study functionally identified a new microRNA (microRNA ovual line 5, miRNVL5) with its target gene GhCHR from cotton (Gossypium hirsutum). The sequence of miRNVL5 precursor is 104 nt long, with a well developed secondary structure. GhCHR contains two DC1 and three PHD Cys/His-rich domains, suggesting that GhCHR encodes a zinc-finger domain-containing transcription factor. miRNVL5 and GhCHR express at various developmental stages of cotton. Under salt stress (50–400 mM NaCl), miRNVL5 expression was repressed, with concomitant high expression of GhCHR in cotton seedlings. Ectopic expression of GhCHR in Arabidopsis conferred salt stress tolerance by reducing Na+ accumulation in plants and improving primary root growth and biomass. Interestingly, Arabidopsis constitutively expressing miRNVL5 showed hypersensitivity to salt stress. A GhCHR orthorlous gene At2g44380 from Arabidopsis that can be cleaved by miRNVL5 was identified by degradome sequencing, but no confidential miRNVL5 homologs in Arabidopsis have been identified. Microarray analysis of miRNVL5 transgenic Arabidopsis showed six downstream genes (CBF1, CBF2, CBF3, ERF4, AT3G22920, and AT3G49200), which were induced by salt stress in wild-type but repressed in miRNVL5-expressing Arabidopsis. These results indicate that miRNVL5 is involved in regulation of plant response to salt stress

    Electron power absorption dynamics in capacitive radio frequency discharges driven by tailored voltage waveforms in CF4

    The power absorption dynamics of electrons and the electrical asymmetry effect in capacitive radio-frequency plasmas operated in CF4 and driven by tailored voltage waveforms are investigated experimentally in combination with kinetic simulations. The driving voltage waveforms are generated as a superposition of multiple consecutive harmonics of the fundamental frequency of 13.56 MHz. Peaks/valleys and sawtooth waveforms are used to study the effects of amplitude and slope asymmetries of the driving voltage waveform on the electron dynamics and the generation of a DC self-bias in an electronegative plasma at different pressures. Compared to electropositive discharges, we observe strongly different effects and unique power absorption dynamics. At high pressures and high electronegativities, the discharge is found to operate in the drift-ambipolar (DA) heating mode. A dominant excitation/ionization maximum is observed during sheath collapse at the edge of the sheath which collapses fastest. High negative-ion densities are observed inside this sheath region, while electrons are confined for part of the RF period in a potential well formed by the ambipolar electric field at this sheath edge and the collapsed (floating potential) sheath at the electrode. For specific driving voltage waveforms, the plasma becomes divided spatially into two different halves of strongly different electronegativity. This asymmetry can be reversed electrically by inverting the driving waveform. For sawtooth waveforms, the discharge asymmetry and the sign of the DC self-bias are found to reverse as the pressure is increased, due to a transition of the electron heating mode from the α-mode to the DA-mode. These effects are interpreted with the aid of the simulation results
