When Nature Counts: Corporate Biodiversity Attention and Access to Bank Finance

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates whether corporate attention to biodiversity influences firms' access to bank loans, an overlooked question in the emerging biodiversity–finance literature. Using a novel, text‐based measure constructed from 446 biodiversity‐related keywords and applied to Chinese A‐share listed firms from 2000 to 2023, we show that ...

Lossless Secret Image Sharing Schemes

CoRR, 2015
Secret image sharing deals with splitting confidential images into several shares and the original image can be reconstructed from the qualified subset of the shares. Secret sharing schemes are used in transmission and storage of private medical images and military secrets. Increased confidentiality and availability are the major achievements.

Multi-Secret Image Sharing Scheme by Boolean Operations

, 2023
Multi-secret image sharing technology shares multiple secret images among participants. The proposed (k, n, m) multi-secret image sharing scheme shares m secret images among n participants and gathering k participants' shared images perfectly recovers ...

What Do We Know About Scope 3 Emissions in Small‐ and Medium‐Sized Enterprises? Mapping Current Knowledge and Advancing a Theory–Practice‐Oriented Framework

Business Strategy and the Environment, EarlyView.
ABSTRACT Although SMEs comprise over 90% of firms globally, research on their engagement with Scope 3 (value‐chain) greenhouse gas emissions remains limited. This PRISMA‐guided systematic review synthesises 49 SME‐relevant studies to develop a theory‐informed, practice‐oriented framework for more credible and sustained Scope 3 engagement.

A Geometry-Based Secret Image Sharing Approach

, 2011
A (k,n) secret image sharing approach shares a protected image to n shared images and gathering k shared images can reconstruct the original image. This paper solves the secret image sharing problem by a geometry secret sharing strategy named the Blakley

From Managing Innovation to Governing Value: Reconceptualizing the Role of Intellectual Property in the Sustainable Business Model

Business Strategy and the Environment, EarlyView.
ABSTRACT The role of intellectual property (IP) in promoting or hindering sustainable innovation now forms a topical issue in innovation management. Its role in the sustainable business model remains imperfectly understood however, creating a simplified view of IP in relation to corporate sustainable development. Hence, this study sought to examine how

Self-verifiable Secret Sharing Scheme with Locatability for Halftone Images

, 2014
[[abstract]]Visual cryptography is an image secret sharing scheme used to encrypt the secret image into several meaningless share images. Later on, the secret image can be obtained while stacking the share images with no computations. However, the secret
