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

Gate Driver Integrated Circuit with Breakdown Protection for Switch-mode Power Amplifiers

This paper proposes a gate driver integrated circuit to prevent breakdown of switching power amplifiers. The proposed circuit consists of a dead-time generator, level shifters, and a breakdown blocker. The dead-time generator makes non-overlapped input signals and the breakdown blocker detects instantaneous turned-on input signals and resets them to the off-state before the switching power cells are damaged. The circuit is designed using TowerJazz\u27s 0.18 um BCD process for a tightly coupled wireless power transfer system. The protecting operation is verified using circuit simulation including layout-dependent characteristics.U ovom radu prikazan je pobudni sklop za sprječavanje kvarnog stanja pojačala snage. Predloženi krug sastoji se od generatora mrtvog vremena, translator razine i sklopa za sprječavanje kvarnog stanja. Generator mrtvog vremena tvori nepreklopljene ulazne signale, a sklop za sprječavanje kvarnog stanja prepoznaje trenutno paljenje ulaznog signala i resetira ih prije nego su ćelije pojačala snage oštećene. Krug je dizajniran koristeći TowerJazz\u27s 0.18 um BCD postupak za povezani sustav bežičnog prijenosa snage. Zaštita je verificirana koristeći simulaciju kruga uključujući karakteristike povezane s izgledom
