Multiple-Tree Push-based Overlay Streaming

Multiple-Tree Overlay Streaming has attracted a great amount of attention from researchers in the past years. Multiple-tree streaming is a promising alternative to single-tree streaming in terms of node dynamics and load balancing, among others, which in turn addresses the perceived video quality by the streaming user on node dynamics or when heterogeneous nodes join the network. This article presents a comprehensive survey of the different aproaches and techniques used in this research area. In this paper we identify node-disjointness as the property most approaches aim to achieve. We also present an alternative technique which does not try to achieve this but does local optimizations aiming global optimizations. Thus, we identify this property as not being absolute necessary for creating robust and heterogeneous multi-tree overlays. We identify two main design goals: robustness and support for heterogeneity, and classify existing approaches into these categories as their main focus

From psychotherapist to supervisor

This study is a part of an ongoing research project examining group supervision in psychotherapy. The study was performed in a postgraduate training program for prospective supervisors. The two-year supervisor training program included theory seminars as well as group supervision of the prospective supervisor’s supervision of a trainee who had a patient in psychotherapy. The training program was based on psychoanalytic theory and the psychotherapy conducted was psychoanalytically oriented. Supervisees´ and supervisors´ experiences of the learning process, supervision format in group and supervisor styles were explored in semi-structured interviews. Both supervisees and supervisors emphasized the importance of a specific training program for psychotherapists who intend to work as supervisors. The didactic aspects of supervision were pointed out. The group format was experienced as particularly suitable for this training level. The “super-supervisor’s” style was important as a role model for the supervisors in training

The Circuit Split on Title VII Personal Supervisor Liability

This Note examines the competing rationales for and against individual supervisor liability under Title VII, and concludes that supervisor liability is the better reasoned view. It explains how courts construe the term employer to either allow or disallow direct supervisor liability. It discusses the rationales for and against individual supervisor liability. It concludes that individual supervisor liability is the better reasoned view, on construction, policy and comparative grounds, and proposes joint and several liability for supervisors and employers in all Title VII cases, which will clarify when respondeat superior liability is appropriate under Title VII. This proposal will deter Title VII violations, remedy plaintiffs appropriately and protect employers from undue vicarious liability
