A low leakage current (Co, Mn, Ta)-SnO2 varistor tailored by doping with chromium for power grids
Results in Physics, 2020 A SnO2 varistor which was prospected to be used in ultra-high voltages grids as an overvoltage protection element was developed. The SnO2 varistor was doped with Cr to improve the comprehensive electrical properties. The optimal electrical parameters are

Estimating the Likelihood of Arrest from Police Records in Presence of Unreported Crimes [PDF]
arXiv, 2023 Many important policy decisions concerning policing hinge on our understanding of how likely various criminal offenses are to result in arrests. Since many crimes are never reported to law enforcement, estimates based on police records alone must be adjusted to account for the likelihood that each crime would have been reported to the police.

Contradictions and Crisis in the World of Work: Informality, Precarity and the Pandemic
Development and Change, Volume 53, Issue 6, Page 1254-1282, November 2022., 2022 ABSTRACT The severe economic impact of the COVID‐19 pandemic on the global working population can be interpreted as both a fallout from, and a violent assertion of, a larger crisis in the world of work. While this crisis has been attributed to the pre‐existing conditions of widespread informality and precarity in the domain of remunerative work, the ...

Strategic Management Journal, EarlyView.Abstract Research Summary Framing is critical for leaders who must build support for strategic renewal. While research has concentrated on renewal that replaces one set of capabilities with another, we explore a distinctive challenge: how leaders persuade stakeholders to endorse the reprioritization of resources toward a capability set that must ...

Control, Extract, Legitimate: COVID‐19 and Digital Techno‐opportunism across Africa
Development and Change, Volume 53, Issue 6, Page 1283-1307, November 2022., 2022 ABSTRACT Across Africa, the deployment of digital solutions such as track and trace apps and vaccine passports to tackle COVID‐19 largely failed in their public health objectives. Yet, in the process, these material interventions revealed and unleashed new potentialities of governance throughout the continent.
