The Effect of Self‐Concept Components on Sustainable Food Choice

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Despite the growing global adoption of sustainable food consumption, the role of self‐concept (including self‐esteem, self‐image, and ideal self) and mindset (beliefs about personal growth and adaptability) in shaping these choices remains underexplored.

Contribution of non‐orthogonal multiple access signalling to practical multibeam satellite deployments

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView., 2023
The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.

Linking the Loop: A Social Network Theory Perspective on the Role of Circularity Brokers for the Circular Economy

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circularity brokers are intermediaries fostering the exchange of circular flows and represent a critical yet underexplored aspect of circular economy. Through social network theory, this paper examines how circularity brokers support creating circular supply chains.

Evaluation of multi‐user multiple‐input multiple‐output digital beamforming algorithms in B5G/6G low Earth orbit satellite systems

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView., 2023
In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such
