Emotion Management Ability: Predicting Task Performance, Citizenship, and Deviance
This article examines emotion management ability (EMA) as a theoretically relevant predictor of job performance. The authors argue that EMA predicts task performance, organizational citizenship behavior (OCB), and workplace deviance behavior. Moreover, to be practically meaningful, managing emotions should predict these important organizational outcomes after accounting for the effects of general mental ability and the Big Five personality traits. Two studies of job incumbents show that EMA consistently demonstrates incremental validity and is the strongest relative predictor of task performance, individually directed OCB, and individually directed and objectively measured deviance
Does Talking the Talk Help Walking the Walk? An Examination of the Effect of Vocal Attractiveness in Leader Effectiveness
The authors tested the hypothesis that leaders\u27 vocal attractiveness is positively related to perceptions of leadership effectiveness. In a first study using vocal spectral analysis on a sample of U.S. presidents and Canadian prime ministers, vocal attractiveness accounted for significant variance in historians\u27 perceptions of leadership effectiveness (β = .35, p \u3c .05), explaining an additional 12% of the variance above that explained by personality, motives, and charisma. A second study of 255 subjects distributed into 85 teams in a laboratory setting found similar results for the relationship between vocal attractiveness and perceptions of leadership effectiveness. The second study also supported the hypothesis that personal reactions mediate the relationship between vocal attractiveness and perceptions of leadership effectiveness. In contrast, vocal attractiveness and personal reactions were found to have no significant effects on leadership effectiveness outcomes
Inhibition of nuclear PTEN tyrosine phosphorylation enhances glioma radiation sensitivity through attenuated DNA repair
Ionizing radiation (IR) and chemotherapy are standard of care treatments for glioblastoma (GBM) patients and both result in DNA damage, however, the clinical efficacy is limited due to therapeutic resistance. We identified a mechanism of such resistance mediated by phosphorylation of PTEN on tyrosine 240 (pY240-PTEN) by FGFR2. pY240-PTEN is rapidly elevated and bound to chromatin through interaction with Ki-67 in response to IR treatment and facilitates the recruitment of RAD51 to promote DNA repair. Blocking Y240 phosphorylation confers radiation sensitivity to tumors and extends survival in GBM preclinical models. Y240FPten knock-in mice showed radiation sensitivity. These results suggest that FGFR-mediated pY240-PTEN is a key mechanism of radiation resistance and is an actionable target for improving radiotherapy efficacy
The Lyman Continuum Escape Fraction of Star-forming Galaxies at from UVCANDELS
The UltraViolet Imaging of the Cosmic Assembly Near-infrared Deep
Extragalactic Legacy Survey Fields (UVCANDELS) survey is a Hubble Space
Telescope (HST) Cycle-26 Treasury Program, allocated in total 164 orbits of
primary Wide-Field Camera 3 Ultraviolet and Visible light F275W imaging with
coordinated parallel Advanced Camera for Surveys F435W imaging, on four of the
five premier extragalactic survey fields: GOODS-N, GOODS-S, EGS, and COSMOS. We
introduce this survey by presenting a thorough search for galaxies at
that leak significant Lyman continuum (LyC) radiation, as well as
a stringent constraint on the LyC escape fraction () from stacking
the UV images of a population of star-forming galaxies with secure redshifts.
Our extensive search for LyC emission and stacking analysis benefit from the
catalogs of high-quality spectroscopic redshifts compiled from archival
ground-based data and HST slitless spectroscopy, carefully vetted by dedicated
visual inspection efforts. We report a sample of five galaxies as individual
LyC leaker candidates, showing estimated
using detailed Monte Carlo analysis of intergalactic medium attenuation. We
develop a robust stacking method to apply to five samples of in total 85
non-detection galaxies in the redshift range of . Most stacks
give tight 2- upper limits below . A stack
for a subset of 32 emission-line galaxies shows tentative LyC leakage detected
at 2.9-, indicating at ,
supporting the key role of such galaxies in contributing to the cosmic
reionization and maintaining the UV ionization background. These new F275W and
F435W imaging mosaics from UVCANDELS have been made publicly available on the
Barbara A. Mikulski Archive for Space Telescopes.Comment: 33 pages, 21 figures, and 5 tables. Resubmitted after addressing the

Labor Mobility And Hypercompetition: Another Challenge To Sustained Competitive Advantages?
Researchers have suggested globalization, technological advances, and the rise of entrepreneurship have ushered in a new era of hypercompetition where competitive advantages are hard to attain and sustain. In this paper we propose another source of hypercompetition—a sudden increase in labor mobility within an industry—by drawing on the resource-based view of what leads to a sustainable competitive advantage. Using data from the National Football League, which had a substantial change in the player mobility in 1993, we use the two-sample Kolmogorov-Smirnov test to stratify teams according to their demonstrated level of competitive (dis)advantage based on their on-field performance. We found support for the hypotheses that an increase in intraindustry labor mobility makes it harder for organizations to sustain a competitive advantage while it is easier for firms at a competitive disadvantage to climb out of the cellar, with dramatic climbs more likely than dramatic falls
Discounting IQ\u27s Relevance To Organizational Behavior: The Somebody Else\u27s Problem In Management Education
We hypothesize the existence of a “somebody else’s problem” in management education for the subdiscipline of organizational behavior (OB). The problem regards human intelligence, specifically, the general factor, g. Although g is arguably the most powerful variable in social science, OB educators largely ignore it. To demonstrate the former, we review a vast literature establishing g’s construct validity. To demonstrate the latter, we show that current OB textbooks place far less emphasis on g relative to a popular but less potent predictor of organizational success, emotional intelligence. We also show that when textbooks do reference g, it is often just to offer criticism. Misconceptions about empirical data on intelligence testing, denial that a general factor of intelligence exists, the reality of mean racial differences in mental ability, and the finding that genes play a non-trivial role in causing intelligence, seem to make OB’s treatment of this topic “somebody else’s problem.
