Proposed Model

The large-scale cascade hydropower plants in southwestern China now challenge a multi-market environment in the new round of electricity market reform. They not only have to supply the load for the local provincial market, but also need to deliver electricity to the central and eastern load centers in external markets, which makes the generation scheduling much more complicated, with a correlated uncertain market environment. Considering the uncertainty of prices and correlation between multiple markets, this paper has proposed a novel optimization model of long-term generation scheduling for cascade hydropower plants in multiple markets to seek for the maximization of overall benefits. The Copula function is introduced to describe the correlation of stochastic prices between multiple markets. The price scenarios that obey the Copula fitting function are then generated and further reduced by using a scenario reduction strategy that combines hierarchical clustering and inconsistent values. The proposed model is applied to perform the long-term generation scheduling for the Wu River cascade hydropower plants and achieves an increase of 106.93 million yuan of annual income compared with the conventional scheduling model, without considering price scenarios, showing better performance in effectiveness and robustness in multiple markets.

Activity Platform

The authors conducted the study of electronic referendum system of the Moscow government "Active Citizen" in order to determine the possibilities of gamification use on the platforms for civil participation, the influence of game mechanics on the civic activity of Russians. The methods of research were the following ones: qualitative analysis of "Active citizen" user feedback, presented on the official Internet portal, as well as user interviews (N = 30). The interview allowed to reveal the motivational attitudes of the respondents' representation on the platform "Active citizen", to evaluate the key parameters of the civil activity platform functioning and the elements of gamification. The result of the study determined that the civil platform creates an opportunity to discuss some important issues for the city. However, with the observation of democratic procedure appearance, there is the substitution of real participation in the state management for the possibility of discussion. The performed study showed the ambivalent nature of gamification use. The respondents demonstrate the polarity of gaming method perception during their transfer to civil platforms: for some participants the possibility of score accumulation is a pleasant bonus to the opportunity to take part in urban problem solution, while it becomes an aim for others and an opportunity to increase one's self-esteem. According to public opinion, the system of electronic referendums of the Moscow government "Active Citizen" will not reduce the demand in the long term

Therapy Sessions

SummaryTwenty-eight schizophrenic and other long-term mentally ill patients who were given cognitive therapy sessions twice a week in the context of a comprehensive inpatient treatment program were assessed every 5 weeks regarding perceived curative factors. The assessments were made by a self-rating questionnaire (Curative Factors Questionnaire [CFQ]) and a qualitative assessment from the patients of what they perceived as helpful in treatment. The results showed that milieu therapeutic elements and therapy sessions were perceived as the most helpful throughout the treatment period. No correlations were found between patient characteristics and perceived curative factors. The factors “instillation of hope”, “problem solution” and “learning I’m not alone” as rated in the initial phase of treatment showed a positive relationship with a favourable outcome of treatment at discharge.
