Generating and Implementing New Ideas in Work Teams: A Motivational Perspective

Creativity and Innovation Management, EarlyView.
ABSTRACT Drawing on motivational perspectives, we develop a framework that explains the psychological mechanisms linking idea generation to implementation. We propose that intrinsically and extrinsically driven idea generation give rise to distinct patterns of team members' commitment to their ideas, which function as key motivational pathways linking ...

Pest‐preservation paradox among insects

Conservation Biology, EarlyView.
The pest‐preservation paradox is a non‐binary perspective that insects range from those that are harmful and requiring management on the one side, to those requiring conservation intervention on the opposite end of the spectrum. Importantly, the vast majority of insects occur somewhere in the center of the two extremes, and their position along the ...

INVESTIGATION OF PARAMETRIC OSCILLATORY MOVEMENTS IN THE AUTOMOTIVE SYSTEM

International Journal of Advanced Studies
The aim of the study is to understand the stability of automotive systems by studying parametric oscillations. The Mathieu function is used to calculate the eigenvalues of the system, which are crucial for determining the behavior of the system over time.

‘A Perpetually Disintegrating Synthesis’: Sartre on Bad Faith, Good Faith, and the Projects of Selfhood

European Journal of Philosophy, EarlyView.
Abstract An oft‐overlooked aspect of Sartre’s concept of selfhood is his rejection of good faith and sincerity as normative ideals. We argue that Sartre’s paradoxical treatment of good faith – claiming both that it is a manifestation of bad faith and the antithesis of it – holds a key to understanding Sartre’s account of selfhood.

Experimental Study on the Fatigue Behavior of Ti‐6Al‐4 V Bolted Joints Containing Burrs

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT One‐way assembly accelerates aerospace manufacturing operations but risks leaving drilling burrs within mechanical joints. The detrimental impact of burrs on fatigue strength is widely recognized in the literature, but the mechanisms driving this “knock‐down” remain unclear. This investigation focused on mechanically fastened Ti‐6Al‐4 V single‐

Modeling of turbulent fluid flow based on the solution of the Mathieu equation

Вестник Дагестанского государственного технического университета: Технические науки
Objective. This work examines the problem of fluid flow simulation in a turbulent regime. The main reasons why turbulent flow occurs are due to the existence of high velocities of movement in fluids; besides that, there may be obstacles or changes in the
