Purpose: This study translated and adapted the It's Your Game, Keep It Real study currently being implemented with middle school youth in Southeast Texas for a middle school population in rural western Honduras. The study tested the effects of a sexual health education program focused on human immunodeficiency virus, sexually transmitted infections, and pregnancy prevention. We hypothesized that the number of adolescents in the intervention group who initiate sexual activity will reduce in comparison to the control group and there will be an increase consistent condom use in sexually active adolescents in the intervention group. ^ Methods: The target population included Spanish-speaking Hispanic middle school students from a small, semi-urban city in western Honduras. One school was randomly selected to receive the intervention and one to the comparison condition. The intervention curriculum consisted of 10 seventh-grade lessons that included individual and group classroom-based activities and personal journaling. Follow-up surveys were completed three months after the last lesson with 146 students (79.3% of the defined cohort). ^ Results: In the comparison condition, 21.4% of students initiated sex by the post-test follow-up three months after the intervention compared to 7.8% in the intervention condition. ^ Conclusions: A multi-component, curriculum-based program that is theory driven and culturally relevant can increase knowledge about STIs and HIV, increase self-confidence amongst middle school students, and develop communication skills amongst friends and partners. Further research must be conducted to assess delay in sexual initiation and the generalizability of these results.^

Researchers have long believed the concept of "excitement" in games to be subjective and difficult to measure. This paper presents the development of a mathematically computable index that measures the concept from the viewpoint of an audience and from that of a player. One of the key aspects of the index is the differential of the probability of "winning" before and after one specific "play" in a given game. The index makes a large contribution to the study of games and enables researchers to compare and analyze the “excitement” of various games. It may be applied in many fields, especially the area of welfare economics, and applications may range from those related to allocative efficiency to axioms of justice and equity.

Recently, steady economic growth rates have been kept in Poland and Hungary. Money supplies are growing rather rapidly in these economies. In large, exchange rates have trends of depreciation. Then, exports and prices show the steady growth rates. It can be thought that per capita GDPs are in the same level and development stages are similar in these two countries. It is assumed that these two economies have the same export market and export goods are competing in it. If one country has an expansion of monetary policy, price increase and interest rate decrease. Then, exchange rate decrease. Exports and GDP will increase through this phenomenon. At the same time, this expanded monetary policy affects another country through the trade. This mutual relationship between two countries can be expressed by the Nash-equilibrium in the Game theory. In this paper, macro-econometric models of Polish and Hungarian economies are built and the Nash- equilibrium is introduced into them.

Some requirements for engineering programmes, such as an ability to use the techniques, skills and modern engineering tools necessary for engineering practice, as well as an understanding of professional and ethical responsibility or an ability to communicate effectively, need new activities designed for measuring students’ progress. Negotiations take place continuously at any stage of a project and, so, the ability of engineers and managers to effectively carry out a negotiation is crucial for the success or failure of projects and businesses. Since it involves communication between individuals motivated to come together in an agreement for mutual benefit, it can be used to enhance these personal abilities. The main objective of this study was to evaluate the adequacy of mixing playing sessions and theory to maximise the students’ strategic vision in combination with negotiating skills. Results show that the combination of playing with theoretical training teaches students to strategise through analysis and discussion of alternatives. The outcome is then more optimised.

Abstract This work is focused on the problem of performing multi‐robot patrolling for infrastructure security applications in order to protect a known environment at critical facilities. Thus, given a set of robots and a set of points of interest, the patrolling task consists of constantly visiting these points at irregular time intervals for security purposes. Current existing solutions for these types of applications are predictable and inflexible. Moreover, most of the previous centralized and deterministic solutions and only few efforts have been made to integrate dynamic methods. Therefore, the development of new dynamic and decentralized collaborative approaches in order to solve the aforementioned problem by implementing learning models from Game Theory. The model selected in this work that includes belief‐based and reinforcement models as special cases is called Experience‐Weighted Attraction. The problem has been defined using concepts of Graph Theory to represent the environment in order to work with such Game Theory techniques. Finally, the proposed methods have been evaluated experimentally by using a patrolling simulator. The results obtained have been compared with previous available
