How important is mentoring in education?
2017
The paper aims to provide the mentoring experience made in Romanian schools, developed as a result of the Erasmus + project entitled “Mentoring Between teachers from secondary and high schools” project No. 2014-1-PL01-KA200-003335. Thus, we seek to present the work and the general considerations in connection with the mentoring theme, how we decided on the curriculum in order to form mentors, how mentors were selected and what was the result of their mentoring work. It is important to observe the main obstacles in the mentoring process were and how these problems could be solved. We will also highlight the impact of the mentoring activity on mentees and their perceptions about the usefulnes…
Continuous hydrothermal synthesis of inorganic nanopowders in supercritical water: towards a better control of the process
2009
International audience; A hydrothermal synthesis process working in supercritical conditions (T > 374 °C, P > 22 MPa) and in a continuous mode has been developed for inorganic nanopowder synthesis. This paper presents a review of the past 5 years of research conducted on this process. Numerous materials (oxides: ZrO2, TiO2, Fe2O3..., ferrites: Fe2CoO4..., or BaZrO3) were obtained with specific features. Some technical issues have been solved, that are presented here. Heat transfer was studied, leading to a more efficient design of the reactor. Future developments have been examined through process engineering, in which our group is engaged, especially through CFD modelling.
Comparison between GPR measurements and ultrasonic tomography with different inversion algorithms: an application to the base of an ancient Egyptian …
2011
By late 2008 one of the most important pieces of the ‘Museo delle Antichit`a Egizie’ of Turin, the sculpture of the Pharaoh with god Amun, was planned to be one of the masterpieces of a travelling exhibition in Japan. The ‘Fondazione Museo delle Antichit`a Egizie di Torino’, who manages the museum, was concerned with the integrity of the base of the statue which actually presents visible signs of restoration dating back to the early 19th century. It was required to estimate the persistence of the visible fractures, to search for unknown ones and to provide information about the overall mechanical strength of the base. To tackle the first question a GPR reflection survey along three sides of…
Using semantics to facilitate data integration of offshore wind farms
2012
Operation and maintenance play an important role in extracting power from the wind, especially, in offshore wind energy where wind farms are located far off the shore and under harsh weather conditions. Improved operation and maintenance is likely to reduce costs as well as hazard exposure of the employees. Implementation of advanced information technology is thus crucial for operating offshore wind farms effectively and efficiently and hence improves operation and maintenance. However, information availability and reliability are key issues for their use in the offshore wind domain. In addition, the semantic of information has not been exploited thoroughly. This paper describes the develop…
Application of Pulsed Electric Field Treatment for Food Waste Recovery Operations
2016
International audience; Food industry is generating annually huge quantities of by-products and waste, which are generally considered as problem, as their disposal is associated with environmental and health related issues. During the last decade, numerous research groups and industries have been interested in valorizing these by-products by extracting valuable compounds and incorporating them generally in food and/or cosmetic products, which enhances the profitability of the process. Conventional extraction methods (i.e., maceration, thermal extraction) are exten- sively used for such purposes and showed high yields in many cases. However, the need to replace toxic organic solvents, shorte…
High performance Athletes dual career support opportunities in the context of the European Union
2015
This article aims to provide an overview of high performance athletes - students dual-career support opportunities in the European Union, in order to create dual career support system in Latvia. The paper provides an explanation of terms, and analyzes the UK, Ireland, Germany, Belgium and other countries' experience in the dual career. In the process is created a comparative overview of the possibilities for support in several European countries. High-performance athletes main types of support are flexible exam schedule, individual study plan, consultations with lecturers, distance learning studies (e-learning), the mentor's advice, and reduced requirements for entrance exams. In Latvia the…

Facilitating Elements for the Transmission of the Entrepreneurial Spirit in the Classroom
2014
There have been countless tests made to confirm that creativity is a critical skill for entrepreneurs and their entrepreneurial training (Schmidt, J. et al. 2012), even more, practices on divergent thinking increases the entrepreneurial skills of students to generate a greater number and range of ideas, but not, their approaches to solve problems in a creative way. This situation raises a number of questions that should be analyzed before adding creativity and techniques to improve the training of creative thinking to studies (classes), about and in entrepreneurship, as a training channel, improvement or even to the generation of entrepreneurs. Our goal is to show that entrepreneurship is a…
Factors Affecting Entrepreneurship and Business Sustainability
2018
Abstract: Sustainability is becoming increasingly important for society, and the creation of business ventures is one area where sustainability is critical. We examined the factors affecting actions that are designed to foster business sustainability. These factors are related to the environment, behavior, human relations, and business activity. Based on questionnaire responses from experts, the Analytic Hierarchy Process (AHP) method was used to rank sustainable business criteria according to their importance for entrepreneurs starting sustainable businesses. The results indicate that the most important drivers of sustainable entrepreneurship are behavioral factors and business factors. Et…
CEOs’ Joy of Working for the Family Firm: The Role of Psychological Ownership and Stewardship Behavior
2021
Abstract In this article, we examine the factors which lead to CEOs’ joy of working for the family firm, as it is expected to contribute to their willingness to invest in its perpetuation and success. We focus on three such factors: CEOs’ collective psychological ownership, their individual psychological ownership, and CEOs’ stewardship behavior. We find that on the one hand, the relationship between CEOs’ collective psychological ownership and their joy of working for the family business is mediated by their stewardship behavior, and on the other hand, stewardship behavior mediates the relationship between CEOs’ individual psychological ownership and their joy of work. We make valuable con…
