TL;DR: In this article, a high-mass X-ray binary (HMXB) with a period of 202 s was detected and its position was consistent with an early B star in the Small Magellanic Cloud (SMC).
Abstract: XMM-Newton archival data for the Small Magellanic Cloud have been examined for the presence of previously undetected X-ray pulsars. One such pulsar, with a period of 202 s, is detected. Its position is consistent with an early B star in the SMC, and we identify it as a high-mass X-ray binary (HMXB). In the course of this study we determined the pulse period of the possible AXP CXOU J010043.1-721134 to be 8.0 s, correcting an earlier report (Lamb et al.) of a 5.4 s period for this object. Pulse profiles and spectra for each of these objects are presented as well as for a recently discovered (Haberl & Pietsch) 263 s X-ray pulsar. Properties of an ensemble of 24 optically identified HMXB pulsars from the SMC are investigated. The locations of the pulsars and an additional 22 X-ray pulsars not yet identified as having high-mass companions are located predominately in the young (ages ≤3 × 107 yr) star-forming regions of the SMC, as expected on the basis of binary evolution models. We find no significant difference between the distribution of spin periods for the HMXB pulsars of the SMC and that of the Milky Way. For those HMXB pulsars that have Be companions we note an inverse correlation between spin period and maximum X-ray flux density. (This anticorrelation has been previously noted for all X-ray binary pulsars by Stella, White, & Rosner) The anticorrelation for the Be binaries may be a reflection of the fact that the spin periods and orbital periods of Be HMXBs are correlated. We note a similar correlation between X-ray luminosity and spin period for the Be HMXB pulsars of the Milky Way and speculate that exploitation of the correlation could serve as a distance indicator.

TL;DR: In this paper, a method for in situ determination of Pb, Pb/Th, and pb/Pb ages in monazite by laser ablation, single-collector, magnetic sector inductively coupled plasma-mass spectrometer (ICP-MS) was presented.
Abstract: [1] Methods are presented for in situ determination of Pb/U, Pb/Th, and Pb/Pb ages in monazite by laser ablation, single-collector, magnetic sector inductively coupled plasma-mass spectrometry (ICP-MS). Analytical precisions for individual spot analyses are ±2–3% for 206Pb/238U and 207Pb/235U, 4% for 208Pb/232Th, and 1–2% for 207Pb/206Pb (2σ, SD). For pooled analyses these precisions are ∼ ± 1–2% for 206Pb/238U, 207Pb/235U, and 208Pb/232Th and ≤1% for 207Pb/206Pb (2σ, SE). When normalized to Trebilcock, LA-ICP-MS ages on other monazite standards can deviate from their thermal ionization mass spectrometry (ID-TIMS) ages by up to 1% for 207Pb/206Pb and up to 5% for 206Pb/238U, 207Pb/235U, and 208Pb/232Th ages. This variability has also been observed for secondary ion mass spectrometry (SIMS) Th-Pb dating. The source(s) of these inaccuracies remains unknown. Although there are significant uncertainties inherent in this technique, U-Th-Pb monazite dating by LA-ICP-MS has important applications where this higher level of uncertainty is acceptable. Application to a large vein monazite from the Llallagua tin district of Bolivia suggests mineralization at 17–21 Ma, consistent with 21 Ma K-Ar ages from wallrock minerals but distinct from ∼45 Ma ages from apatite (Sm/Nd) and zircon (Pb/Pb).

TL;DR: Results indicated that humility is held in high regard by others, and two factors emerged from exploratory factor analysis that appear to converge on measuring humility, with acceptable convergent and divergent validity and internal consistency reliability.
Abstract: Humility is a psychological construct that has not received much empirical attention until recently. This new emphasis on positive psychology and humility has been both conceptual and empirical. The present study had two objectives: to review the literature briefly to verify the importance of humility and its positive perception by others, and to begin to develop a preliminary measure of humility. Results indicated that humility is held in high regard by others. Two factors emerged from exploratory factor analysis that appear to converge on measuring humility, with acceptable convergent and divergent validity and internal consistency reliability. These results are discussed in terms of the expected relationships among humility and other constructs (e.g., social desirability, narcissism, self-esteem).

TL;DR: In the Garhwal region, India, the Malari leucogranite cuts the South Tibetan detachment system, a large-scale normal fault system at the top of the High Himalaya.
Abstract: In the Garhwal region, India, the Malari leucogranite cuts the South Tibetan detachment system, a large-scale normal fault system at the top of the High Himalaya. The leucogranite crosscuts ductile normal-sense shear fabrics and has experienced relatively little subsolidus brittle deformation or alteration. Its relatively evolved bulk chemical composition, high Rb/Sr ratio, and normative corundum indicate a (meta)sedimentary source, likely the underlying Greater Himalayan sequence. Zircon U-Pb ages, collected by laser-ablation inductively coupled plasma–mass spectrometry (ICP-MS) and corrected for initial U/Th disequilibrium, indicate emplacement at 19.0 ± 0.5 Ma. Thus, ductile normal shear on the South Tibetan detachment system must have ceased by 19 Ma. Studies elsewhere in the Himalaya suggest initiation of South Tibetan detachment system ductile movement not earlier than 24 Ma, and likely ca. 22 Ma. The short duration of extension (≤5 and likely ∼3 m.y.) and early cessation contrast with channel-flow models that predict long-duration ductile normal shear, and large displacements after ca. 20 Ma. Observations are instead better explained by critical taper models, in which internal weakening of the wedge, likely from partial melting, caused a brief interval of flattening and ductile extension in the rear of the wedge.

TL;DR: While civility scores remained mild to moderately high overall, there was a slightly declining trend over the 3-year period, and perceived stressors and coping strategies and ways to improve academic civility are discussed.
Abstract: Academic incivility can increase student stress, jeopardize learning, damage relationships, and negatively impact the academic environment. This 3-year longitudinal study measured a cohort of prelicensure nursing students' progressive perceptions of stress, coping, student-student and faculty-student relationships, and levels of academic civility. While civility scores remained mild to moderately high overall, there was a slightly declining trend over the 3-year period. Perceived stressors and coping strategies and ways to improve academic civility are identified and discussed.
