From Comparison to Collaboration: Experiments with a New Scholarly and Political Form

Society and the workplace are two factors that are important for the individual's health status. It is important that the individuals has the right skills to take care of their health. For organizations, it is important to strive for the welfare of their employees. This has proven to have a positive impact on work performance, reduced absenteeism and reduced costs for rehabilitation. In 2007, the local authorities in Umeå implemented a wellness offering for all employees working in the municipality administration. They later saw a need to assist employees who needed help getting started with new exercise habits. This study aims to examine how the participants in the "Get Started Programme", succeeded in creating lasting exercise habits , 3-4 years after completing the program. Research questions are: How have the participants increased their knowledge practically and theoretically after the programme has finished? How have the participants succeeded in creating the content of the programme in their daily lives? How do the participants assess their health compared to before they participated in the programme? Are there any beneficial factors highlighted by the participants as during the program? The study was conducted on the basis of semi-structured interviews with eight voluntary participants who previously participated in the Get Started Programme. The results show that six of the eight participants succeeded to get started with the goals for behavioral change, and still maintain a sufficient physical activity level today. Participants who do not consider themselves to have succeeded in reaching the goals they set up in the beginning of the program, point out that they have the tools needed to go on and continue the behavioral change they strive for

Preparing for and adapting to climate change impacts: Next steps for the Washington state department of National Resources Aquatic Resources Program

In response to a growing body of research on projected climate change impacts to Washington State’s coastal areas, the Washington State Department of Natural Resources’ (DNR) Aquatic Resources Program (the Program) initiated a climate change preparedness effort in 2009 via the development of a Climate Change Adaptation Strategy (the Strategy)i. The Strategy answers the question “What are the next steps that the Program can take to begin preparing for and adapting to climate change impacts in Washington’s coastal areas?” by considering how projected climate change impacts may effect: (1) Washington’s state-owned aquatic landsii, (2) the Program’s management activities, and (3) DNR’s statutorily established guidelines for managing Washington’s state-owned aquatic lands for the benefit of the public. The Program manages Washington’s state-owned aquatic lands according to the guidelines set forth in Revised Code of Washington 79-105-030, which stipulates that DNR must manage state-owned aquatic lands in a manner which provides a balance of the following public benefits: (1) Encouraging direct public uses and access; (2) Fostering water-dependent uses; (3) Ensuring environmental protection; (4) Utilizing renewable resources. (RCW 79-105-030) The law also stipulates that generating revenue in a manner consistent with these four benefits is a public benefit (RCW 79-105-030). Many of the next steps identified in the Strategy build off of recommendations provided by earlier climate change preparation and adaptation efforts in Washington State, most notably those provided by the Preparation and Adaptation Working Group, which were convened by Washington State Executive Order 70-02 in 2007, and those made in the Washington Climate Change Impacts Assessment (Climate Impacts Group, 2009).

Thermoreversible Associating Polymer Networks: I. Interplay of Thermodynamics, Chemical Kinetics, and Polymer Physics

Hybrid molecular dynamics/Monte Carlo simulations used to study melts of unentangled, thermoreversibly associating supramolecular polymers. In this first of a series of papers, we describe and validate a model that is effective in separating the effects of thermodynamics and chemical kinetics on the dynamics and mechanics of these systems, and is extensible to arbitrarily nonequilibrium situations and nonlinear mechanical properties. We examine the model's quiescent (and heterogeneous) dynamics, nonequilibrium chemical dynamics, and mechanical properties. Many of our results may be understood in terms of the crossover from diffusion-limited to kinetically-limited sticky bond recombination, which both influences and is influenced by polymer physics, i. e. the connectivity of the parent chains.Comment: Many minor revisions; accepted for publication in JC

Orientations of the lamellar phase of block copolymer melts under oscillatory shear flow

We develop a theory to describe the reorientation phenomena in the lamellar phase of block copolymer melt under reciprocating shear flow. We show that similar to the steady-shear, the oscillating flow anisotropically suppresses fluctuations and gives rise to the parallel-perpendicular orientation transition. The experimentally observed high-frequency reverse transition is explained in terms of interaction between the melt and the shear-cell walls.Comment: RevTex, 3 pages, 1 figure, submitted to PR
