Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

Strategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

Linking Pulse‐Duration‐Controlled Laser Nanostructuring to Oxygen Evolution Kinetics in Fe‐enriched NiOx Electrodes

Small, EarlyView.
Pulse‐duration‐controlled ultra‐short laser processing is shown to directly create binder‐free Fe‐enriched NiOx electrodes with tunable porosity, active‐site density, and oxygen‐evolution kinetics. Shorter pulses generate defect‐rich nanostructures that accelerate charge transfer, promote highly active NiFeOOH formation, and deliver durable alkaline ...

Microwave-discharge hall thruster

Microwave-discharge hall thruster
A novel type of Hall thruster featuring plasma generated by electromagnetic waves of various types is being investigated at ISAS. A Hall stage with a non-conventional downstream magnetic circuit has been designed for use with a variety of non-traditional plasma production devices, including ECR microwave cavity, and RF plasma sources.

Systems‐Based Organisational Resilience Framework: A Delphi Study‐Based Validation and Verification

Systems Research and Behavioral Science, EarlyView.
ABSTRACT The increasing systemic complexity of the Fourth Industrial Revolution has heightened the need for robust approaches to organisational resilience. Despite its growing prominence, resilience research remains fragmented, with limited consensus on core dimensions, causal interdependencies and mechanisms suitable for dynamic assessment. This study

Early use of the reinforced concrete in the architecture of the Historicism in Austria–Hungary

Structural Concrete, EarlyView.
Abstract The study examines the early incorporation of reinforced concrete in the architecture of Historicism in Austria–Hungary. Spanning the late 19th to early 20th centuries, the research illuminates the period's stylistic pluralism and the transformative impact of reinforced concrete.

The Pier Luigi Nervi's concrete structure of Palazzetto dello Sport: Modeling and dynamic characterization

Structural Concrete, EarlyView.
Abstract This paper presents a numerical and experimental study aimed at the modeling and dynamic characterization of the reinforced concrete structure of the Palazzetto dello Sport in Rome, designed and by Pier Luigi Nervi with Annibale Vitellozzi, and built by Nervi & Bartoli contractors in 1956‐57.

The clashing of in situ and pre‐cast technologies—Western trends and local traditions in concrete engineering shaping shell construction in 20th‐century Hungary

Structural Concrete, EarlyView.
Abstract After a blossoming pre‐World War II (WWII) period, the concrete construction industry in then‐socialist Hungary existed in a relative isolation from the Western World during the mid‐20th century. In this paper, we focus on the body of work of one of the then newly established state‐owned design offices, IPARTERV, to show how the isolation ...
