Women’s Leadership Is Associated With Fewer Deaths During the COVID-19 Crisis: Quantitative and Qualitative Analyses of United States Governors

The coronavirus disease that emerged in 2019 (COVID-19) spotlights the need for effective leadership in a crisis. Leadership research in applied psychology suggests that women tend to be preferred over men as leaders during uncertain times. We contribute to this literature by examining, in the context of COVID-19, whether states with women governors had fewer deaths than states with men governors, and why. We tested this research question with publicly available data on COVID-19 deaths in the United States as of May 5, 2020 and found that states with women governors had fewer COVID-19 deaths compared to states with men governors. Governor sex also interacted with early stay-at-home orders; states with women governors who issued these orders early had fewer deaths compared to states with men governors who did the same. To provide insight into psychological mechanisms of this relationship, we conducted a qualitative analysis of governor briefings that took place between April 1, 2020 and May 5, 2020 (251 briefings, 38 governors, 1.2 million words). Compared to men, women governors expressed more empathy and confidence in their briefings. Practical implications are discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved)

Prime and Prejudice

Drawing upon theoretical perspectives from applied and social psychology, sociology, and management literatures, we develop a conceptual model in which conscious and subconscious prejudice interact to cause work discrimination. We posit that consciously non-prejudiced employees can face cognitive trade-offs outside of awareness that stem from a contradictory pull of primed subconscious prejudice. This cognitive paradox can lead to unintended, automatic discriminatory behaviour. Understanding the interplay between conscious lack of prejudice and primed subconscious prejudice, ostensibly, has greater organisational implications than studying either one alone. This is because employees cannot effectively grapple with unintended work discrimination without a more complete understanding of mechanisms that trigger these behaviours without awareness. In this article, we fuse new and prior points to offer novel theory insights

Fabrication methods for a quantum cascade photonic crystal surface emitting laser

Conventional quantum cascade (QC) lasers are intrinsically edge-emitting devices with mode confinement achieved via a standard mesa stripe configuration. Surface emission in edge emitting QC lasers has therefore necessitated redirecting the waveguided laser emission using a second order grating. This paper describes the methods used to fabricate a 2D photonic crystal (PC) structure with or without a central defect superimposed on an electrically pumped QC laser structure with the goal of achieving direct surface emission. A successful systematic study of PC hole radius and spacing was performed using e-beam lithography. This PC method offers the promise of a number of interesting applications, including miniaturization and integration of QC lasers

Fabrication technologies for quantum cascade photonic-crystal microlasers

In this paper we describe the technological and fabrication methods necessary to incorporate both photonic and electronic-band engineering in order to create novel surface-emitting quantum cascade microcavity laser sources. This technology offers the promise of several innovative applications such as the miniaturization of QC lasers, and multi-wavelength two-dimensional laser arrays for spectroscopy, gas-sensing and imaging. This approach is not limited to light-emitting devices, and may be efficiently applied to the development of mid- and far-infrared normal-incidence detectors

Quantum cascade photonic crystal surface emitting injection laser

A surface emitting quantum cascade injection laser is presented. Direct surface emission is obtained by using a 2D photonic-band-gap structure that simultaneously acts as a microcavity. The approach may allow miniaturization and on-chip-integration of the devices

Prime and Performance: Can a CEO Motivate Employees Without Their Awareness?

Work motivation research is at a crossroads with the discovery of the causal effects of primed subconscious goals in addition to those of consciously set goals on performance. Although social psychologists continue to demonstrate positive effects of primed goals on a multitude of dependent variables, priming research has been criticized for its lack of generalizability beyond tightly controlled laboratory experiments. Addressing this skepticism, a field experiment was conducted in a for-profit organization, where the CEO used goal priming to motivate job performance. A performance goal for achievement was primed with achievement-related words embedded in an email from the CEO to employees. The goal priming by the CEO necessitated little to no costs yet it increased objectively measured performance effectiveness by 15% and efficiency by 35% over a 5-day work-week. This field experiment illustrates a new alternative for increasing employee performance. In a second experiment, we conducted a conceptual replication of the field experiment in the laboratory with a larger sample size, and we extended theory by testing a measure of motivation level as a mediator of the primed goal-performance effect. The results affirmed the hypothesized motivational influence. These two experiments increase understanding of subconscious motivation processes

Test of three conceptual models of influence of the big five personality traits and self-efficacy on academic performance: A meta-analytic path-analysis

The Big Five personality traits and self-efficacy independently relate to a multitude of outcomes across domains of functioning. Yet, only a small number of studies examined these variables together as part of the same conceptual model, and findings are mixed. We revisit their joint relationships, and test three conceptual models of influence on academic performance of college students over a semester. Because of the key role college graduates will play in society, many have a stake in better understanding their performance. The trait model specifies that the Big Five traits influence performance directly and indirectly through partial mediation of self-efficacy. In the independent model, the Big Five traits influence self-efficacy and performance independently, without mediation of self-efficacy. In the intrapersonal model, the effects of the Big Five traits on performance are fully mediated by self-efficacy. We collected data in five samples, three Universities, and two countries, N = 875, and conducted a meta-analytic path-analysis. Self-efficacy positively related to academic performance across the models, conscientiousness and emotional stability were predictive of self-efficacy and performance in some analyses, and the significance of the other three traits was fleeting

Impact of spin-orbit coupling on quantum Hall nematic phases

Anisotropic charge transport is observed in a two-dimensional (2D) hole system in a perpendicular magnetic field at filling factors nu=7/2, nu=11/2, and nu=13/2 at low temperature. In stark contrast, the transport at nu=9/2 is isotropic for all temperatures. Isotropic hole transport at nu=7/2 is restored for sufficiently low 2D densities or an asymmetric confining potential. The density and symmetry dependences of the observed anisotropies suggest that strong spin-orbit coupling in the hole system contributes to the unusual transport behavior.Comment: 4 pages, 4 figure

Bias-Dependent Generation and Quenching of Defects in Pentacene

We describe a defect in pentacene single crystals that is created by bias stress and persists at room temperature for an hour in the dark but only seconds with 420nm illumination. The defect gives rise to a hole trap at Ev + 0.38eV and causes metastable transport effects at room temperature. Creation and decay rates of the hole trap have a 0.67eV activation energy with a small (108 s-1) prefactor, suggesting that atomic motion plays a key role in the generation and quenching process.Comment: 10 pages, 3 figure
