Survey on Deduplication Techniques in Flash-Based Storage

Data deduplication importance is growing with the growth of data volumes. The domain of data deduplication is in active development. Recently it was influenced by appearance of Solid State Drive. This new type of disk has significant differences from random access memory and hard disk drives and is widely used now. In this paper we propose a novel taxonomy which reflects the main issues related to deduplication in Solid State Drive. We present a survey on deduplication techniques focusing on flash-based storage. We also describe several Open Source tools implementing data deduplication and briefly describe open research problems related to data deduplication in flash-based storage systems

Nonmonetary Strategies to Increase Employee Job Satisfaction in Nonprofit Organizations

Nonprofit organizations\u27 managers face challenges in creating nonmonetary rewards to increase the job satisfaction of staff and productivity of the organization. The purpose of this multiple case study was to explore the nonmonetary reward strategies that nonprofit organizations\u27 managers used to increase employee job satisfaction. The targeted population included nonprofit managers who had successfully implemented nonmonetary reward strategies to increase employee job satisfaction. Kalleberg\u27s theory of job satisfaction was the conceptual framework for the study. The primary data collection method was semistructured, face-to-face interviews with 3 participants. Secondary data sources included review of company documents such as employee evaluations and work-from-home request forms. Methodological triangulation of data and information was accomplished by comparing data collected from interviews and company documents. Through coding and thematic analysis, 3 primary themes emerged: experience, effective communication, and flexibility. The primary conclusion of this study was that managers use personal experiences as an employee to develop and implement effective reward systems. The implications of this study for social change include the potential to improve employee job satisfaction in nonprofit organizations, which may result in improved employee productivity and promote social development in the community
