Semantic Communications for Wireless Sensing: RIS-Aided Encoding and Self-Supervised Decoding

, 2023
Semantic communications can reduce the resource consumption by transmitting task-related semantic information extracted from source messages. However, when the source messages are utilized for various tasks, e.g., wireless sensing data for localization ...

Greenwashing Across Industries: A Scoping Review of Explanatory Factors, Reporting Tactics, and Disclosure‐Action Decoupling

Business Strategy and the Environment, EarlyView.
ABSTRACT This scoping review provides an industry‐comparative synthesis of greenwashing and disclosure‐action decoupling in sustainability‐related reporting. Guided by PRISMA, it reviews 73 peer‐reviewed articles published between 2016 and 2025 and organizes them into three streams: variable‐based explanatory, report analysis, and disclosure‐action ...

Semantic diversity:A measure of contextual variation in word meaning based on latent semantic analysis [PDF]

, 2013
Semantic ambiguity is typically measured by summing the number of senses or dictionary definitions that a word has. Such measures are somewhat subjective and may not adequately capture the full extent of variation in word meaning, particularly for ...

Disclosure, Verification, and Value: The Impact of Climate Risk Disclosure on Institutional On‐Site Research and Economic Consequences

Business Strategy and the Environment, EarlyView.
ABSTRACT Based on signaling theory and information asymmetry theory, this study uses a sample of Chinese A share listed firms from 2012 to 2023 to examine the effect of climate risk disclosure (CRD) on institutional on‐site research and its economic consequences.

Cross-layer secure semantic communications with generative adversarial network-based semantic noise

EURASIP Journal on Advances in Signal Processing
This paper proposes a novel generative adversarial network (GAN)-based cross-layer secure semantic communication framework that jointly optimizes semantic representation, physical-layer security, and adversarial robustness against eavesdroppers.

Semantic Communications With World Models

IEEE Transactions on Communications
Semantic communication is a promising technique for emerging wireless applications, which reduces transmission overhead by transmitting only task-relevant features instead of raw data. However, existing methods struggle under extremely low bandwidth and varying channel conditions, where corrupted or missing semantics lead to severe reconstruction ...

Measuring Corporate Energy Transition Through Web‐Based Evidence and Large Language Models

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper proposes a scalable method to measure firm‐level engagement with the energy transition using corporate website disclosures and large language models (LLMs). We construct a restrictive, policy‐aligned rubric that codes evidence of (i) energy efficiency improvements, (ii) decarbonization and emissions‐reduction strategies, and (iii ...

A Model for Quantifying the Degree of Understanding in Cross-Domain M2M Semantic Communications

IEEE Access
This paper addresses the problem of semantic communications (SemComs) in intelligent machine-to-machine (M2M) applications. Although M2M applications may employ other languages as the communication medium, natural languages are commonly used as the ...

Bounded Rationality and Greenwashing: An Information‐Architecture Signalling Framework for Verification Frictions and the Disclosure–Performance Gap

Business Strategy and the Environment, EarlyView.
ABSTRACT Green claims pervade corporate communications, yet their informational value varies because stakeholders process them under bounded rationality—scarce attention and costly verification. This paper develops a conceptual signalling framework in which three parameters—signal diagnosticity (D), verification frictions (V) and available attention (A)
