T1  - An extensive spectroscopic time series of three Wolf-Rayet stars - I. The lifetime of large-scale structures in the wind of WR 134
JF  - Monthly notices of the Royal Astronomical Society
N2  - During the summer of 2013, a 4-month spectroscopic campaign took place to observe the variabilities in three Wolf-Rayet stars. The spectroscopic data have been analysed for WR 134 (WN6b), to better understand its behaviour and long-term periodicity, which we interpret as arising from corotating interaction regions (CIRs) in the wind. By analysing the variability of the He ii lambda 5411 emission line, the previously identified period was refined to P = 2.255 +/- 0.008 (s.d.) d. The coherency time of the variability, which we associate with the lifetime of the CIRs in the wind, was deduced to be 40 +/- 6 d, or similar to 18 cycles, by cross-correlating the variability patterns as a function of time. When comparing the phased observational grey-scale difference images with theoretical grey-scales previously calculated from models including CIRs in an optically thin stellar wind, we find that two CIRs were likely present. A separation in longitude of Delta I center dot a parts per thousand integral 90A degrees was determined between the two CIRs and we suggest that the different maximum velocities that they reach indicate that they emerge from different latitudes. We have also been able to detect observational signatures of the CIRs in other spectral lines (C iv lambda lambda 5802,5812 and He i lambda 5876). Furthermore, a DAC was found to be present simultaneously with the CIR signatures detected in the He i lambda 5876 emission line which is consistent with the proposed geometry of the large-scale structures in the wind. Small-scale structures also show a presence in the wind, simultaneously with the larger scale structures, showing that they do in fact co-exist.

T1  - Estimating the reproducibility of psychological science
JF  - Science
N2  - Reproducibility is a defining feature of science, but the extent to which it characterizes current research is unknown. We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered designs and original materials when available. Replication effects were half the magnitude of original effects, representing a substantial decline. Ninety-seven percent of original studies had statistically significant results. Thirty-six percent of replications had statistically significant results; 47% of original effect sizes were in the 95% confidence interval of the replication effect size; 39% of effects were subjectively rated to have replicated the original result; and if no bias in original results is assumed, combining original and replication results left 68% with statistically significant effects. Correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.

T1  - Validierung des Singing Voice Handicap Index in der deutschen Fassung
JF  - HNO
N2  - Der Singing Voice Handicap Index (SVHI) wurde zur Selbstbeurteilung einer Stimmstörung für Sänger in den USA entwickelt. Eine deutsche Übersetzung wurde erstellt und einer Reliabilitäts- und Validitätsprüfung unterzogen. Es wurden 54 dysphone Sänger (35 weiblich, 19 männlich), Patienten einer phoniatrischen Klinik, befragt. 130 stimmgesunde Opern- und Rundfunkchorsänger (74 weiblich, 56 männlich) bildeten die Kontrollgruppe. Die Reliabilität ergibt sich aus einer hochsignifikanten Test-Retest-Reliabilität (r = 0,960; p <= 0,001, Pearson-Korrelation) und einem Cronbach-? von 0,975. Eine Hauptkomponentenanalyse mit Varimaxrotation und die Ergebnisse des Screeplots legen die Interpretation des SVHI als einfaktorielle Skala nahe. Die Validität zeigt sich in einem hochsignifikanten Zusammenhang zwischen dem vom Patienten selbst eingeschätzten Schweregrad der Stimmstörung und dem SVHI-Gesamtscore. Patienten haben einen signifikant höheren SVHI-Gesamtscore als die Kontrollgruppe gesunder Sänger. Der SVHI ist als diagnostisches Instrument für den deutschsprachigen Raum geeignet.
