An increasingly rapid technological progress in the era of globalization in the business world, so do not rule out the possibility that a decision-making is something that is very vital in determining the decisions to be taken in the face of competitive business world. Decision making can be influenced by several aspects, this can affect the speed of decision making by the decision maker in which decisions must be quick and accurate. Lecturer Performance Assessment Using the Analytical Hierarchy Process is a decision support system that aims to assess faculty performance according to certain criteria. This system of faculty performance appraisal criteria to map a hierarchy, where each hierarchy will be performed pairwise comparison, the pairwise comparisons between criteria, so to get a comparison of the relative importance of criteria with each other. The results of this comparison is then analyzed to obtain the priority of each criterion. Once completed and performed an assessment of alternative options to be compared and calculated to obtain the best alternatives according to established criteria.

The future of cardiothoracic surgery faces a lofty challenge with the advancement of percutaneous technology and minimally invasive approaches. Coronary artery bypass grafting (CABG) surgery, once a lucrative operation and the driving force of our specialty, faces challenges with competitive stenting and poor reimbursements, contributing to a drop in applicants to our specialty that is further fueled by the negative information that members of other specialties impart to trainees. In the current era of explosive technological progress, the great diversity of our field should be viewed as a source of excitement, rather than confusion, for the upcoming generation. The ideal future cardiac surgeon must be a "surgeon-innovator," a reincarnation of the pioneering cardiac surgeons of the "golden age" of medicine. Equipped with the right skills, new graduates will land high-quality jobs that will help them to mature and excel. Mentorship is a key component at all stages of cardiothoracic training and career development. We review the main challenges facing our specialty�length of training, long hours, financial hardship, and uncertainty about the future, mentorship, and jobs�and we present individual perspectives from both residents and faculty members.

On the go is the development and adaptation of an individual target for Bulgaria, in order to increase the share of RES energy, according to the EU common vision for leadership in the implementation of renewables to 32% in the gross final consumption by 2030. The technological progress, the easy applicability and feasibility of the projects, as well as the geographic and climatic specifics of Bulgaria, makes photovoltaic Bulgaria's main candidate for leading technology in this process. With net specific production of 1323kWh/annual per installed kWp, price levels of PV technology of €1360kWp and Levelized cost of energy (LCOE) below €0.12kWh for 20 years time frame, households in Bulgaria are at a stage where photovoltaic projects should be developed as an alternative to the grid supply

This is the first volume of a groundbreaking commentary on one of the most important works of ancient philosophy, the Enneads of Plotinus—a text that formed the basis of Neoplatonism and had a deep influence on early Christian thought and medieval and Renaissance philosophy. This volume covers the first three of the six Enneads, as well as Porphyry’s Life of Plotinus, a document in which Plotinus’s student—the collector and arranger of the Enneads—introduces the philosopher and his work. A landmark contribution to modern Plotinus scholarship, this commentary is the most detailed and extensive ever written for the whole of the Enneads. For each of the treatises in the first three Enneads, the volume provides a brief introduction that presents the philosophical background against which Plotinus’s contribution can be assessed; a synopsis giving the main lines and the articulation of the argument; and a running commentary placing Plotinus’s thought in its intellectual context and making evident the systematic association of its various parts with each other.

Abstract Agri-food systems include branching ramifications, which connect in the upstream the input suppliers with farmers, and downstream farmers, processors, retailers and consumers. In the last decades, at the level of the regions, food systems have undergone rapid transformation as a result of technological progress. The paper analyzes the changes made to the structure, behavior and performance of the agri-food system and the impact on farmers and consumers. Also, the role of agricultural research as a determinant factor of transformation of agri-food system is analyzed. The research objective is to develop technologies that cover the entire food chain (from farm to fork) and meet the specific requirements of consumers (from fork to farm) through scientific solutions in line with the principles of sustainable agriculture and ensuring the safety and food safety of the population.
