A Historiometric Examination of Machiavellianism and a New Taxonomy of Leadership

Although researchers have extensively examined the relationship between charismatic leadership and Machiavellianism (Deluga, 2001; Gardner & Avolio, 1995; House & Howell, 1992), there has been a lack of investigation of Machiavellianism in relation to alternative forms of outstanding leadership. Thus, the purpose of this investigation was to examine the relationship between Machiavellianism and a new taxonomy of outstanding leadership comprised of charismatic, ideological, and pragmatic leaders. Using an historiometric approach, raters assessed Machiavellianism via the communications of 120 outstanding leaders in organizations across the domains of business, political, military, and religious institutions. Academic biographies were used to assess twelve general performance measures as well as twelve general controls and five communication specific controls. The results indicated that differing levels of Machiavellianism is evidenced across the differing leader types as well as differing leader orientation. Additionally, Machiavellianism appears negatively related to performance, though less so when type and orientation are taken into account.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

The forward physics facility at the high-luminosity LHC

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing LHC experiments. The proposed Forward Physics Facility (FPF), to be located several hundred meters from the ATLAS interaction point and shielded by concrete and rock, will host a suite of experiments to probe standard model (SM) processes and search for physics beyond the standard model (BSM). In this report, we review the status of the civil engineering plans and the experiments to explore the diverse physics signals that can be uniquely probed in the forward region. FPF experiments will be sensitive to a broad range of BSM physics through searches for new particle scattering or decay signatures and deviations from SM expectations in high statistics analyses with TeV neutrinos in this low-background environment. High statistics neutrino detection will also provide valuable data for fundamental topics in perturbative and non-perturbative QCD and in weak interactions. Experiments at the FPF will enable synergies between forward particle production at the LHC and astroparticle physics to be exploited. We report here on these physics topics, on infrastructure, detector, and simulation studies, and on future directions to realize the FPF's physics potential

Hybrid Aromatic Fluoro Amine Modified SnO2 Electron Transport Layers in Perovskite Solar Cells for Enhanced Efficiency and Stability

SnO2 is a widely used electron transporting layer in perovskite solar cells. Despite the high compatibility with the perovskite absorber layers the presence of traps at the perovskite SnO2 interface results in performance losses, hence their modification to improve the performance and stability of PSCs is therefore important. In this study, we enhanced the SnO2 ETL by incorporating a bi functional aromatic amino fluorine molecule into the SnO2 precursor solution. The fluorine molecule was found to partially substitute the Sn and alter the energy levels while the aniline group aided in regulating the nucleation growth rate of the perovskite crystalline films. In this work, a hole transporting material free carbon based PSCs CPSCs was fabricated. We found that perovskite absorber layers deposited on these modified SnO2 hybrid layers have higher optoelectronic quality, resulting in enhanced photovoltaic performance, device stability, and reduced hysteresis in CPSCs. Devices made with the modified hybrid SnO2 layers exhibited PCEs of 15.6 significantly better than unmodified SnO2 with 13.5 . CPSCs with these modified SnO2 films also exhibited remarkable retention of 88.7 of their initial power conversion efficiency for a shelf life period ISOS D1I exceeding 1200 h. This study presents a generic approach to enhance the stability and performance of CPSCs by modifying the properties of the electron transport layer and, consequently, regulating the quality of the perovskite materia
