Access control in collaborative systems

Abstract: Balancing the competing goals of collaboration and security is a difficult, multidimensional problem. Collaborative systems often focus on building useful connections among people, tools, and information while security seeks to ensure the availability, confidentiality, and integrity of these same elements. In this article, we focus on one important dimension of this problem---access control. The article examines existing access control models as applied to collaboration, highlighting not only the benefits, but also the weaknesses of these models.

Assessment of variation in microbial community amplicon sequencing by the Microbiome Quality Control (MBQC) project consortium

Abstract: In order for human microbiome studies to translate into actionable outcomes for health, meta-analysis of reproducible data from population-scale cohorts is needed. Achieving sufficient reproducibility in microbiome research has proven challenging. We report a baseline investigation of variability in taxonomic profiling for the Microbiome Quality Control (MBQC) project baseline study (MBQC-base). Blinded specimen sets from human stool, chemostats, and artificial microbial communities were sequenced by 15 laboratories and analyzed using nine bioinformatics protocols. Variability depended most on biospecimen type and origin, followed by DNA extraction, sample handling environment, and bioinformatics. Analysis of artificial community specimens revealed differences in extraction efficiency and bioinformatic classification. These results may guide researchers in experimental design choices for gut microbiome studies.

Posttraumatic Growth, Meaning in Life, and Life Satisfaction in Response to Trauma

Abstract: A model of the processes leading to posttraumatic growth and to life satisfaction following exposure to trauma was tested. Two types of repeated thought, deliberate and intrusive, posttraumatic symptoms, posttraumatic growth, and meaning in life, were assessed as predictors of general life satisfaction. Challenges to core beliefs were shown to be related to both intrusive and deliberate rumination. The two forms of rumination were in turn differentially related to posttraumatic growth and posttraumatic distress. Distress and posttraumatic growth were independently and oppositely related to meaning in life and to life satisfaction. Overall, the best fitting model was supportive of proposed posttraumatic growth models. Additional exploratory analyses examined participant groupings, based of self-reported category of resolution of the traumatic experience, and differences supportive of proposed underlying processes were found.

The Role of Work Context in Work Motivation: A Public Sector Application of Goal and Social Cognitive Theories

Abstract: The present study represents a test of a conceptual model predicting how the organization’s work context might influence work motivation. Using the framework provided by goal and social cognitive theories, this model of work motivation assesses whether aspects of the organizational work context, such as greater goal conflict, procedural constraints, and goal ambiguity, may have a detrimental effect on work motivation through their influence on three important antecedents of work motivation: job goal specificity, job difficulty, and self-efficacy. Although the findings of a covariance (LISREL) analysis of state government employee survey data suggested a few minor modifications to this model, the results indicated that the theoretical framework can identify specific leverage points that can increase work motivation and, therefore, productivity in the public sector.
