Implementation of novel methods of global and nonsmooth optimization : GANSO programming library

We discuss the implementation of a number of modern methods of global and nonsmooth continuous optimization, based on the ideas of Rubinov, in a programming library GANSO. GANSO implements the derivative-free bundle method, the extended cutting angle method, dynamical system-based optimization and their various combinations and heuristics. We outline the main ideas behind each method, and report on the interfacing with Matlab and Maple packages.

Small-scale randomized controlled trials need more powerful methods of mediational analysis than the Baron-Kenny method

Objective: To devise more-effective physical activity interventions, the mediating mechanisms yielding behavioral change need to be identified. The Baron–Kenny method is most commonly used, but has low statistical power and may not identify mechanisms of behavioral change in small-to-medium size studies. More powerful statistical tests are available.
Study Design and Setting: Inactive adults (N = 52) were randomized to either a print or a print-plus-telephone intervention. Walking and exercise-related social support were assessed at baseline, after the intervention, and 4 weeks later. The Baron–Kenny and three alternative methods of mediational analysis (Freedman–Schatzkin; MacKinnon et al.; bootstrap method) were used to examine the effects of social support on initial behavior change and maintenance. Results: A significant mediational effect of social support on initial behavior change was indicated by the MacKinnon et al., bootstrap, and, marginally, Freedman–Schatzkin methods, but not by the Baron–Kenny method. No significant mediational effect of social support on maintenance of walking was found. Conclusions:  Methodologically rigorous intervention studies to identify mediators of change in physical activity are costly and labor ntensive, and may not be feasible with large samples. The use of statistically powerful tests of mediational effects in small-scale studies can inform the development of more effective interventions.

Effects of differential methods of compensation and employee empowerment on customer satisfaction and loyalty in service recovery

This research examined the effects of varying compensation (refund and replacement) and employee empowerment (empowered and non-empowered) in service recover situations, using a 2x2 experiment. Analysis was undertaken using mean contrasts and ANOVA's. Findings suggest that empowerment and refund independently impact on post recovery consumer loyalty and satisfaction, but there is no interaction effect.

Healthy minds : methods of investigation

We'll start this chapter by looking at emthods used to assess mental disorders, using depression an an example. We will then look at ways of evaluating psychological interventions.  Finally we will outline ways that healthy minds have been investigated, drawing particularly on research methods that study happiness, personal strengths and spirituality.
