Adoption of Clawback Provisions and Compensation Shielding Effect of R&D Expenditures: The Role of Compensation Committee Quality.

Fatigue crack propagation in near-threshold regime was studied in the 304L austenitic stainless steel in two microstructural states: as-received (AR) with finer microstructure and low susceptibility to the transformation-induced plasticity (TRIP) effect, and solution-annealed (SA) with coarser microstructure and higher susceptibility to TRIP. At the load ratio R = 0.1 the threshold was higher in the SA state than in the AR state due to coarser grains and possibly the TRIP effect. In order to clarify the role of crack closure, experiments at R = 0.7 were done. The threshold in the SA state was still higher by 1 MPa·m0.5. This effect was identified as crack tip shielding induced by phase transformation, an example of a non-closure shielding effect. Higher resistance to crack growth in the SA state was attributed to promoted martensitic transformation in non-favorable oriented grain families rather than thicker martensite layers in the crack path area. The conclusions were verified by experiments at R = 0.7 and temperature 150 °C > Ms which did not reveal any notable difference in thresholds. However, the threshold values were affected by the load-shedding gradient C = −dΔK/da, which had to be equalized in both experimental setups inside and outside the furnace.

Tribological properties of the experimental grades of high entropy hard alloys with modified binding phase on cobalt, which are characterized by minimal value of absolute t.m.f. to carbide phase, were experimentally investigated. It was established experimentally that new grades obtain better friction characteristics in comparison with the base alloy grade VK8 because friction processes of these materials in contact with structural steels are characterized by lower friction forces and lower temperatures in the friction zones. The ‘third body’ which is thicker than for the base alloy grade VK8, obtains a positive gradient of mechanical properties in friction zone, has a shielding effect, reduces the rate of generation of adhesive joints (welding bridges), and, perhaps, performs the role of dry lubrication.

Coronavirus Infection

Presently the world is battling a deadly pandemic without any effective licenced drugs or biologics to vanquish SARSCoV-2. The experience of managing the past viral aetiological outbreaks has been extrapolated to nCOVID-19, yet its effectiveness is uncertain. This connotation invokes a potential insight to focus upon those elements and etiquettes which are an integral part of our life and expound for nCOVID-19 treatment. This further impels us to consider our food as a time-tested medicine. In a study, a decrease in Vitamin-D levels accounted for the bovine coronavirus infection in calves. Interestingly it paves the way for exploring the role of Vitamin-D as an accessible 'magic bullet' against nCOVID-19. Currently, its metabolism and immunomodulatory characterization are well-established. In fact, the studies have described an inverse relationship between Vitamin-D level and respiratory infections. This further substantiates for understanding its shielding effect against nCOVID-19. Few researchers have recommended dosage of Vitamin-D intake among adult and highrisk individuals including front-liners. However, the enforcement of this potent nutritional ergogenic calls for dose rationalisation with due effectivity and safety based on large randomized controlled trials. This short review highlights the important scientic link between Vitamin D levels and susceptibility to COVID-19 in patients.

Purpose The purpose of this study is to investigate how compensation committee structure or characteristic impacts say on pay (SOP) voting dissent and the impact of SOP dissent on chief executive officer (CEO) turnover. Design/methodology/approach The authors use corporate governance and SOP data to test the relationships amongst variables. Additional analysis is performed using one-to-one propensity-score matched samples. Findings The authors find that firm-years with at least a female member present on the compensation committee are associated with lower SOP dissent. The authors find mixed results of the impact of SOP dissent on CEO turnover. Practical implications This paper suggests that diversity on the compensation committee, particularly the presence of at least a female member on the committee, serves as an important determinant of SOP voting outcome in the USA. The paper provides policymakers and practitioners with insights into factors influencing SOP voting outcomes and implications of SOP dissent for firms. Originality/value The findings of this paper contribute to the corporate governance literature by enhancing the understanding of the role of the compensation committee as it relates to SOP dissent and effect of SOP dissent on CEO turnover.
