Research investigating the validity of personality measures has established these measures as useful selection tools. However, personality measures are vulnerable to response distortion leading to ...employer concerns about the influence of applicant faking, with specific concerns about the influence of social desirability. A traditional method used to circumvent this is the application of a correction based on a social desirability scale score. This study sought to evaluate whether such corrections are effective tools for removing the influence of intentional distortion. A within-subjects design facilitated comparisons between honest, faked, and corrected scores. The goal was to evaluate whether a social desirability correction allows one to approximate an individual's honest score. The results suggest that a social desirability correction is ineffective and fails to produce a corrected score that approximates an honest score. Results are interpreted with respect to applicant comparison and construct validity.
The Collaborative Computational Project No. 4 (CCP4) is a UK‐led international collective with a mission to develop, test, distribute and promote software for macromolecular crystallography. The CCP4 ...suite is a multiplatform collection of programs brought together by familiar execution routines, a set of common libraries and graphical interfaces. The CCP4 suite has experienced several considerable changes since its last reference article, involving new infrastructure, original programs and graphical interfaces. This article, which is intended as a general literature citation for the use of the CCP4 software suite in structure determination, will guide the reader through such transformations, offering a general overview of the new features and outlining future developments. As such, it aims to highlight the individual programs that comprise the suite and to provide the latest references to them for perusal by crystallographers around the world.

The Advanced LIGO detectors have recently completed their second observation run successfully. The run lasted for approximately 10 months and led to multiple new discoveries. The sensitivity to ...gravitational waves was partially limited by laser noise. Here, we utilize auxiliary sensors that witness these correlated noise sources, and use them for noise subtraction in the time domain data. This noise and line removal is particularly significant for the LIGO Hanford Observatory, where the improvement in sensitivity is greater than 20%. Consequently, we were also able to improve the astrophysical estimation for the location, masses, spins, and orbital parameters of the gravitational wave progenitors.
The Square Kilometre Array (SKA) project is an international effort to build the world's largest radio telescope, enabling science with unprecedented detail and survey speed.The project spans over a ...decade and is now at a mature stage, ready to enter the construction and integration phase. In the fully deployed state, the MID-Telescope consists of a 150-km diameter array of offset Gregorian antennas installed in the radio quiet zone of the Karoo desert (South Africa). Each antenna is equipped with three feed packages, that are precision positioned in the sub-reflector focus by a feed indexer platform. The total observational bandwidth (0.35-15.4GHz) is segmented into seven bands. Band 1 (0.35 - 1.05 GHz) and Band 2 (0.95 - 1.76 GHz) are implemented as individual feed packages. The remaining five bands (Bands 3, 4, 5a, 5b, and 6) are combined in a single feed package. Initially only Band 5a (4.6 - 8.5 GHz) and Band 5b (8.3 - 15.4 GHz) will be installed. This paper provides an overview of recent progress on design, test and integration of each feed package as well as project and science goals, timeline and path to construction.
In the present study, we assessed the effects of exercise intensity on salivary immunoglobulin A (s-IgA) and salivary lysozyme (s-Lys) and examined how these responses were associated with salivary ...markers of adrenal activation. Using a randomized design, 10 healthy active men participated in three experimental cycling trials: 50% maximal oxygen uptake (VdotO
2max
), 75%VdotO
2max
, and an incremental test to exhaustion. The durations of the trials were the same as for a preliminary incremental test to exhaustion (22.3 min, s
x
= 0.8). Timed, unstimulated saliva samples were collected before exercise, immediately after exercise, and 1 h after exercise. In the incremental exhaustion trial, the secretion rates of both s-IgA and s-Lys were increased. An increase in s-Lys secretion rate was also observed at 75%VdotO
2max
. No significant changes in saliva flow rate were observed in any trial. Cycling at 75%VdotO
2max
and to exhaustion increased the secretion of α-amylase and chromogranin A immediately after exercise; higher cortisol values at 75%VdotO
2max
and in the incremental exhaustion trial compared with 50%VdotO
2max
were observed 1 h immediately after exercise only. These findings suggest that short-duration, high-intensity exercise increases the secretion rate of s-IgA and s-Lys despite no change in the saliva flow rate. These effects appear to be associated with changes in sympathetic activity and not the hypothalamic - pituitary - adrenal axis.
The physical relationship between low-excitation gas filaments at ~10 super(4) K, seen in optical line emission, and diffuse X-ray emitting coronal gas at ~10 super(7) K in the centers of many galaxy ...clusters is not understood. It is unclear whether the ~104 K filaments have cooled and condensed from the ambient hot (~10 super(7) K) medium or have some other origin such as the infall of cold gas in a merger, or the disturbance of an internal cool reservoir of gas by nuclear activity. Observations of gas at intermediate temperatures (~10 super(5)-10 super(6) K) can potentially reveal whether the central massive galaxies are gaining cool gas through condensation or losing it through conductive evaporation and hence identify plausible scenarios for transport processes in galaxy cluster gas. Here we present spectroscopic detection of ~105 K gas spatially associated with the H alpha filaments in a central cluster galaxy, M87, in the Virgo Cluster. The measured emission-line fluxes from triply ionized carbon (C IV 1549 Angstrom) and singly ionized helium (He II 1640 Angstrom) are consistent with a model in which thermal conduction determines the interaction between hot and cold phases.
New measurements of the mechanical loss factors of hydroxide-catalysis bonds have been made and these have been found to be significantly lower than previously reported. We provide the first estimate ...for the resulting thermal noise limitation for a practical test mass geometry for next generation gravitational wave detectors.
