Mapping Multi‐Stakeholder Engagement: A Q Methodology in a Regional Project Management Scenario
Strategic Change, EarlyView.ABSTRACT Research on project management describes the essence of projects involving multiple stakeholders, stressing the value derived from diverse work practices. However, this underestimates issues of counterproductive disagreements associated with diverse groups participating in a project.

THE FORMATION AND DISSIPATION OF A METEOR COMA
Odessa Astronomical Publications, 2017 The results of reduction of instantaneous fireball photographs are presented. The observational data testify to the fact that linear dimensions of the region radiating after the meteor’s flight amount to tens and hundreds of meters, and in the case of ...

Strategic Change, EarlyView.ABSTRACT This paper considers the tensions between different organizational strategic decision‐making approaches at various levels of uncertainty. Of particular focus are the mechanisms for defaulting to lower uncertainty, from the Cynefin framework's unordered chaotic and complex domains to the more ordered complicated and obvious domains.

Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Measuring impulse from explosive charges in contact and near‐field configurations presents practical challenges due to wide variation in impulse magnitude. Ballistic pendula are widely used for impulse measurement, but many existing designs are limited to narrow operating envelopes or are poorly suited to repeated contact testing and tamped ...

Direct Measurement of Explosive Impulse From Contact to the Ultra‐Near Field
Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Measurement of impulse from explosive charges in contact and ultra‐near‐field regimes remains poorly characterised due to the short duration of loading, high strain rates, and the difficulty of obtaining direct momentum‐based measurements.

A bifluidic model formalism analyzing sheath plasma resonance in inverted fireballs
Results in PhysicsThe sheath plasma resonance (SPR) in an inverted fireball (IFB) system is semi-analytically investigated in the framework of a generalized hydrodynamic isothermal model formalism comprising of electron–ion fluids.

Photo‐responsive carbon dots for pyroptosis‐mediated anti‐tumor application
Responsive Materials, EarlyView.Photo‐responsive CDs generate ROS to induce tumor cell pyroptosis, thereby stimulating antitumor immunity. Abstract Pyroptosis refers to a kind of lytic programmed cell death, characterized by the release of pro‐inflammatory cytokines during the process. Owing to its immune response stimulation ability, pyroptosis has garnered considerable attention in
