    This study investigated the effects of taurine on repeated sprint exercise, performed after fixed incremental ramp exercise to exhaustion at isokinetic high (90 r/min) or low (50 r/min) cadences. In a double-blind, repeated measures design, nine females completed an incremental ramp test to volitional exhaustion, followed by 2 min active recovery and 6 × 10 s sprints on a cycle ergometer, in one of four conditions: high cadence (90 r/min) + taurine (50 mg/kg body mass); high cadence + placebo (3 mg/kg body mass maltodextrin); low cadence (50 r/min) + taurine; low cadence + placebo. Heart rate (HR) and blood lactate concentration B[La] were measured before and after the ramp test and after the sprints. Taurine lowered HR vs. placebo prior to the ramp test (P = 0.004; d = 2.1). There was an effect of condition on ramp performance (P < 0.001), with higher end-test power (d = 3.7) in taurine conditions. During repeated sprints, there was a condition × time interaction (P = 0.002), with higher peak sprint power in the placebo conditions compared to taurine (sprint 2–6; P < 0.05). B[La] was higher in taurine compared to placebo post-ramp (P = 0.004; d = 4.7). Taurine-lowered pre-exercise HR and improved incremental end-test power output, with subsequent detrimental effects on sprint performance, independent of cadence. Short endurance performance can be acutely enhanced after taurine ingestion but this effect might not be maintained across longer periods of exercise or induce the need for longer recovery periods

    Introduction: Rethinking democratization and election observation

    Get PDF
    This book brings together studies on the broad theme of elections and democratization in Africa since roughly 1989. It is based on a seminar held in The Netherlands in February 1997, and includes chapters on both electoral processes, especially the role of foreign observers therein, and the historical and sociocultural backgrounds or contexts of democratization, elections and political legitimacy. Part 1 deals with elections and election observation in Africa in general (contributions by O. van Cranenburgh, S. Ellis, I. van Kessel, B. de Gaay Fortman). Part 2 consists of country studies (M. Doornbos on Uganda, D. Foeken en T. Dietz on Kenya, J. Abbink on Ethiopia, R. van Dijk on Malawi, R. Buijtenhuijs on Chad, and M.-F. Lange on Mali). Part 3 includes a chapter that reflects the discussions held at the seminar between observers, academics and policymakers in the Netherlands Ministry of Foreign Affairs (W. van Binsbergen en J. Abbink); a review of Dutch policies on election observation in Africa during the period 1992-1997 (O. van Cranenburgh); and a discussion of the 1997 general elections in Kenya, where a new approach of election observation was introduced (M.

    On Keeping Promises

    A collection of articles based on three lectures given at a seminar arranged by Norges Bank and the Norwegian Academy of Science and Letters. The articles were published in Nytt Norsk Tidsskrift 1/2009 (in Norwegian) under the heading “Symposion: On keeping promises”. Only minor revisions have been made in the English translation. A seminar entitled “On keeping promises” was hosted by Norges Bank and the Norwegian Academy of Science and Letters on 11 November 2008. In modern political science, this topic has been analysed as the “Odysseus motive” in Jon Elster’s seminal work Ulysses and the Sirens (1979): Odysseus let himself be bound to the mast to prevent him from being seduced by the song of the sirens. Elster’s theory has inspired Francis Sejersted in his interpretation of the Norwegian state as a constitutional democracy, with predictability as an essential element. In his introduction, Deputy Governor Jan F. Qvigstad discusses the dilemmas facing monetary policy from the same perspective. Qvigstad’s lecture and commentaries by Endre Stavang and Henrik Syse are included here, followed by Francis Sejersted’s concluding remarks on the dilemmas of binding
