Struggling with and for. A Grounded Theory of Parents Managing Life with Hard-to-Treat ADHD Teenagers

The aim of this study was to develop a grounded theory of being a parent of hard-totreat teenagers with the diagnosis of ADHD. Caretakers of 11 adolescents with ADHD were interviewed and analyzed according to the principles of classic grounded theory. The parents’ main concern was how to handle everyday challenges with the teenagers and how to get the help they needed and required. Struggling with and for is the core category in our findings. In addition, we identified four sub-categories: good “mothering”, advocating, seeking support, and giving up. The meeting with the helping services causes just as many problems as the relationship with the teenagers. Professionals should be able to identify family strengths and capabilities. In that way, professional support can be built upon coping strategies with which a family is already familiar

Optimal Allocation of Norwegian Offshore Wind Power : A Copula Approach : How can a thoughtful placement of offshore wind parks reduce variability in production output?

This thesis investigates how to optimize stable wind production along the coast of Norway. The research is carried out by studying how well a compound dependency model, consisting of a time series and copula model, for simulation of wind power data performs compared to historical data when optimizing a portfolio for wind power production areas. The weights for the areas in the portfolio are computed so that the areas with the most stable joint power production are included. The findings of this research will contribute to the understanding of how effective different optimization approaches for offshore wind park placements are and provide insights into the selection of optimal areas for offshore wind power development in Norway. The study's findings indicate that portfolio optimization performed on simulated data performs better than on historical data. Consequently, zero and low production values are reduced, and stability is increased for the portfolio made with simulated data. Moreover, Value at Risk (VaR) is argued to be a better performance measure for stable wind production than variance. The portfolio distribution when maximizing VaR is more left-skewed than the portfolio minimizing variance. Thus, maximizing VaR results in a higher variance, but less zero and low production values, and a higher average production which is argued to be more important. The positive effect of dispersed wind parks regarding stable wind production is evident. Following the pattern of diminishing correlation as distance increases, the optimal combination of wind parks includes places throughout the Norwegian coast. All areas are included in the optimal solution, but the most influential areas which should be prioritized are Sørlige Nordsjø 2, South of Kristiansand, West of Tromsø, and North of Tanafjorden. When the criteria for stable wind production is extended to include a penalty factor for low average production, diversification is partly de-prioritized to include areas with high average production, among these, more southern areas are included.nhhma
