Gestión de los Centros Educativos de Educación Primaria, Tipo Dirección Uno, Circuito 06 Katira, Dirección Regional de Educación Zona Norte Norte
An management assessment was made of  3 Mode 1 public high schools belonging to the Northern Educational Region Circuit 6 in the Northern Region of Costa Rica in 2013. The general objectives were to assess and propose enhancements to management activities for the high schools participating in the study. The objectives specifically include: 1 – Acknowledging strengths and weaknesses in the schools´curriculum, teaching staff, financial limitations, educational resources and procedures.  2 – Determine the principal management strategies embraced by principals in teh aforementioned instittutions. The study is qualitative.  Findings include: principals overloaded with work, decontexualized content, general lack of motivation among teachers in the workplace and lack of adequate classrooms to provide a quality education
Liderazgo para una gestión moderna de procesos educativos
The authors` essay on social contextualization considers education, highlighting the social complexity of educational development and challenges when society demands information. Within this context, the role of modern management and leadership is redefined and its relationship to the achievement of societyÂ´s educational objectives and aims. Personal characteristics and leadership practices of modern educational management are reconsidered, as well as key quality factors of educational management. The components of educational leadership are developed.
Preparation and performance evaluation of swine manure bio-oil modified rubber asphalt binder
Abstract In order to study the effect of the preparation process of swine manure bio-oil modified rubber asphalt binder on the rheological properties of the binder, the matrix asphalt and asphalt rubber were used as the control group, and swine manure bio-oil modified rubber asphalt binders were obtained by three preparation processes. Then the rheological properties of five binders were evaluated by rotational viscosity, DSR, MSCR and BBR tests. The results show that the addition of swine manure bio-oil to asphalt rubber is beneficial to the workability, but cause negative effect on its high temperature performance, fatigue performance and low temperature crack resistance. The preparation method of premixing bio-oil and rubber powder can reduce the degradation of high-temperature performance of asphalt rubber caused by addition of swine manure bio-oil to a certain extent. The fatigue properties of the three bio-binders are close, and the critical temperature is less than 25 °C. The process of premixing bio-oil and rubber powder will increase the creep stiffness and reduce the low-temperature performance. However, the low-temperature performance of the binder obtained by this process is still better than that of the matrix asphalt and can meet the requirements of use. Therefore, it is recommended to use the preparation process of premixing bio-oil and rubber powder to prepare swine manure bio-oil modified asphalt rubber.
