Insights from the Federal Mediation and Conciliation Service

In recent years, mediation has become increasingly popular as a means to resolve conflict. One important issue that arises out of the recent explosive growth in the practice of mediation is. what do mediators need to know in order to assist the parties in resolving their conflicts? This research attemtps to identify the determinants of mediator competence by examining the knowledge, skills and abilities of mediators in public sector labor relations. The research focuses on the core competencies requirements for mediators with the Federal Mediation and Conciliation Service and suggests which of the competencies may be applicable to mediation in other contexts.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Recurrent and recent selective sweeps in the piRNA pathway

Uncontrolled transposable element (TE) insertions and excisions can cause chromosome breaks and mutations with dramatic deleterious effects. The PIWI interacting RNA (piRNA) pathway functions as an adaptive TE silencing system during germline development. Several essential piRNA pathway proteins appear to be rapidly evolving, suggesting that TEs and the silencing machinery may be engaged in a classical "evolutionary arms race." Using a variety of molecular evolutionary and population genetic approaches, we find that the piRNA pathway genes rhino, krimper, and aubergine show patterns suggestive of extensive recurrent positive selection across Drosophila species. We speculate that selection on these proteins reflects crucial roles in silencing unfamiliar elements during vertical and horizontal transmission of TEs into naïve populations and species, respectively
