Traditional centralised data storage and processing solutions manifest limitations with regards to overall operational cost and the security and auditability of data. One of the biggest issues with existing solutions is the difficulty of keeping track of who has had access to the data and how the data may have changed over its lifetime; while providing a secure and easyto-use mechanism to share the data between different users. The ability to electronically regulate data sharing within and across different organisational entities in the supply-chain (SC), is an open issue, that is only addressed partially by existing legal and regulatory compliance frameworks. In this work, we present Cydon, a decentralised data management platform that executes bespoke distributed applications utilising a novel search and retrieve algorithm leveraging metadata attributes. Cydon utilises a smart distributed ledger to offer an immutable audit trail and transaction history for all different levels of data access and modification within a SC and for all data flows within the environment. Results suggest that Cydon provides authorised and fast access to secure distributed data, avoids single points of failure by securely distributing encrypted data across different nodes while maintains an "always-on" chain of custody.
Disabled people face hostility and harassment in their socio-cultural environment. The use of electronic communications creates an online context that further reshapes this discrimination. We explored the experiences of 19 disabled victims of cyberharassment. Five themes emerged from the study: disability and health consequences, family involvement, misrepresentation of self, perceived complexity, and lack of awareness and expertise. Cyberharassment incidents against disabled people were influenced by the pre-existing impairment, perceived hate-targeting, and perpetrators faking disability to get closer to victims online. Our findings highlight a growing issue requiring action and proper support.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
