Leadership, task and relationship: Orpheus, Prometheus and Janus

The idea that the major division in leadership or management styles is a preference for either task or relationship orientation has long prevailed in the literature. This article proposes an alternative orientation for leaders; that, while in pursuit of achieving the task, the leader is focused either on the needs of superordinates or subordinates, or both. A large-scale evaluation of leadership in the Royal Air Force from the perspective of followers suggests that although there is some surface support for the task/relationship dichotomy, the more important division is threefold: between people who only look upwards to satisfy the demands of their superordinates (Orpheans), those that tend to focus downwards at the demands of their subordinates (Prometheans) and those that try to look both ways (Janusians). The latter appear to have the greatest chance of sustained success at the more senior levels of the organisation

The T2K experiment

The T2K experiment is a long baseline neutrino oscillation experiment. Its main goal is to measure the last unknown lepton sector mixing angle θ13 by observing νe appearance in a νμ beam. It also aims to make a precision measurement of the known oscillation parameters, and sin22θ23, via νμ disappearance studies. Other goals of the experiment include various neutrino cross-section measurements and sterile neutrino searches. The experiment uses an intense proton beam generated by the J-PARC accelerator in Tokai, Japan, and is composed of a neutrino beamline, a near detector complex (ND280), and a far detector (Super-Kamiokande) located 295 km away from J-PARC. This paper provides a comprehensive review of the instrumentation aspect of the T2K experiment and a summary of the vital information for each subsystem
