Preliminary Design of Reactive Distillation Columns

A procedure that combines feasibility analysis, synthesis and design of reactive distillation columns is introduced. The main interest of this methodology lies on a progressive introduction of the process complexity. From minimal information concerning the physicochemical properties of the system, three steps lead to the design of the unit and the specification of its operating conditions. Most of the methodology exploits and enriches approaches found in the literature. Each step is described and our contribution is underlined. Its application is currently limited to equilibrium reactive systems where degree of freedom is equal to 2 or less than 2. This methodology which provides a reliable initialization point for the optimization of the process has been applied with success to different synthesis. The production of methyl-tert-butyl-ether (MTBE) and methyl acetate are presented as examples

Generating dialogical practices in mental health : experiences from southern Norway, 1998-2008

Published version of an article in the journal: Administration and Policy in Mental Health and Mental Health Services Research. Also available from the publisher at: http://dx.doi.org/10.1007/s10488-013-0479-3In Norway and many other countries, political guidelines prescribe the development of mental health strategies with both a service user's perspective and a treatment system established by the local authority. The development of new strategies frequently involves challenges regarding procedures and treatment as well as a view of knowledge and humanity. Dialogical practices might provide a solution for these challenges not only because of its procedures but also due to its attitudes toward service users. The aim is to explore the implementation of three dialogical practice programs in Southern Norway from 1998 to 2008 and to critically analyze and discuss the authors' experiences during the implementation process. Three different programs of dialogical practices were initiated, established, and evaluated within the framework of participatory action research. Sustainable changes succeed individually and organizationally when all participants engage as partners during the implementation of new mental health practices. Generating dialogic practice requires shared understanding of the Open Dialogue Approach (ODA) and collaboration between professional networks and among the leaders. Developing a collaboration area that includes service users in all stages of the projects was one of the essential implementation factors. Other factors involved a common vision of ODA by the leaders and the actors, similar experiences, and a culture of collaboration. However, ODA challenged traditional medical therapy and encountered obstacles to collaboration. Perhaps the best way of surmounting those obstacles is to practice ODA itself during the implementation process

The Multidimensional Work Motivation Scale: Validation evidence in seven languages and nine countries

Self-determination theory proposes a multidimensional conceptualization of motivation comprising autonomous and controlled forms. Whereas autonomous motivation relates positively to individuals’ optimal functioning (e.g., well-being, performance), controlled motivation is less beneficial. To be able to use self-determination theory in the field of organizational behaviour, the Multidimensional Work Motivation Scale was developed and tested using data from 3435 workers in seven languages and nine countries. Factorial analyses indicated that the 19-item scale has the same factor structure across the seven languages. Convergent and discriminant validity tests across the countries also indicate that the psychological needs for autonomy, competence, and relatedness as well as the theoretically derived antecedents to work motivation (e.g., leadership and job design) are predictably related to the different forms of motivation, which in turn are predictably related to important work outcomes (e.g., well-being, commitment, performance, and turnover intentions). Implications for the development of organizational research based on self-determination theory are discussed
