  abstract  = {This article addresses security and privacy issues associated with storing data in public cloud services. It presents an architecture based on a novel secure cloud gateway that allows client systems to store sensitive data in a semi-trusted multi-cloud environment while providing confidentiality, integrity, and availability of data. This proxy system implements a space-efficient, computationally-secure threshold secret sharing scheme to store shares of a secret in several distinct cloud datastores. Moreover, the system integrates a comprehensive set of security measures and cryptographic protocols to mitigate threats induced by cloud computing. Performance in practice and code quality of the implementation are analyzed in extensive experiments and measurements. (C) 2016 Elsevier B.V. All rights reserved.},

  abstract  = {Involvement of disadvantaged individuals into entrepreneurship facilitates their social integration into mainstream societies. The present study addresses the drivers of social entrepreneurial appraisal among hearing-impaired individuals within a unique social minority environment. In prior research, social appraisal was empirically shown to determine social entrepreneurial intention. Adopting the theory of planned behaviour, this study investigates the impact of entrepreneurial self-efficacy, general social support and perceived barriers on social entrepreneurial appraisal. Based on a survey with 221 respondents, our results demonstrate that social entrepreneurial appraisal of hearing-impaired individuals result from their entrepreneurial self-efficacy and general social support. In terms of taking advantage of social opportunities, importance should be given to the role of entrepreneurial education and heterogeneous networks across minorities.},

  abstract  = {Background: Cloud computing promises to essentially improve healthcare delivery performance. However, shifting sensitive medical records to third-party cloud providers could create an adoption hurdle because of security and privacy concerns. Methods: We empirically investigate our research question by a survey with over 260 full responses. For the setting with a high confidentiality assurance, we base on a recent multi-cloud architecture which provides very high confidentiality assurance through a secret-sharing mechanism: Health information is cryptographically encoded and distributed in a way that no single and no small group of cloud providers is able to decode it.},
