Failure or progress?: The current state of the professionalisation of midwifery in Europe

INTRODUCTION Throughout Europe midwives called for increasing professionalisation of midwifery during the 1980s and 1990s. While the Bologna Declaration, in 1999, supported this development in education and research, it remains unclear how other fields, such as practice, have fared so far. This study therefore aimed to explore the current state of professionalisation of midwifery in Europe. METHODS An exploratory inquiry was conducted with an on-line semi- structured questionnaire. Its content was based on the Greenwood sociological criteria for a profession. Descriptive statistics and thematic content analysis were used to analyse the data. Participants were national delegates from member countries to the European Midwives Association. RESULTS Delegates from 29 European countries took part. In most countries, progress towards professionalisation of midwifery has been made through the move of education into higher education, coupled with opportunities for postgraduate education and research. Lack of progress was noted, in particular in regard to midwifery practice, regulation, and leadership in health care provision and education. Most countries had a code of ethics for midwives as well as a midwifery association. Based on organisational collaborations with other disciplines, the sustainability of a distinct professional culture was unclear. An increased focus on future development of midwifery practice was proposed. CONCLUSIONS Progress in midwifery education and research has taken place. However, midwives’ current roles in practice as well as leadership and their influence on healthcare culture and politics are matters of concern. Future efforts for advancing professionalisation in Europe should focus on the challenges in these areas

Generator voltage stabilisation for series-hybrid electric vehicles

This paper presents a controller for use in speed control of an internal combustion engine for series-hybrid electric vehicle applications. Particular reference is made to the stability of the rectified DC link voltage under load disturbance. In the system under consideration, the primary power source is a four-cylinder normally aspirated gasoline internal combustion engine, which is mechanically coupled to a three-phase permanent magnet AC generator. The generated AC voltage is subsequently rectified to supply a lead-acid battery, and permanent magnet traction motors via three-phase full bridge power electronic inverters. Two complementary performance objectives exist. Firstly to maintain the internal combustion engine at its optimal operating point, and secondly to supply a stable 42 V supply to the traction drive inverters. Achievement of these goals minimises the transient energy storage requirements at the DC link, with a consequent reduction in both weight and cost. These objectives imply constant velocity operation of the internal combustion engine under external load disturbances and changes in both operating conditions and vehicle speed set-points. An electronically operated throttle allows closed loop engine velocity control. System time delays and nonlinearities render closed loop control design extremely problematic. A model-based controller is designed and shown to be effective in controlling the DC link voltage, resulting in the well-conditioned operation of the hybrid vehicle

Distributed control of chemical process networks

In this paper, we present a review of the current literature on distributed (or partially decentralized) control of chemical process networks. In particular, we focus on recent developments in distributed model predictive control, in the context of the specific challenges faced in the control of chemical process networks. The paper is concluded with some open problems and some possible future research directions in the area
