Abstract: People use hierarchical decision models (HDMs) in industrial and academic fields. The closer collaborative relationships among the researchers have the world of research in HDM shrinking. We want to identify the clusters of the researchers and the central member of them in order to build up connection, trying to make the new research widely known and the collaboration done. The social network analysis method is employed to analyze the network of HDM researchers who are connected by co-authorship in the selected papers. We find out the most important researchers with the highest degree centralities and publication frequencies; we also identify the core researchers in the Top 8 components. By acting as the “information gatekeeper” and connecting the identified researchers, the average distance between the vertices is significantly eliminated and we form a smaller world in the research realm of HDMs.

Abstract: This article presents a local entropy based image reconstruction algorithm that performs quite well in cases where there is distortion in an image. If the “wanted” image information is still available but distributed over two or more distinct images, the algorithm can collect the required information from the set of the images given. Instead of inferring pixel data information from the remainder of one single image, the algorithm provides a decision rule on what information from which one of the set of given images to actually use in order to create a new, (ideally) distortion-free image.

Abstract: The studies in higher education have its natural focus on the subject matters of study. This also holds for the master program Technology Management (TM). In addition, it is important to complement the students’ academic knowledge with insights about metacognition, i.e. knowledge and understanding of themselves and their own behaviour. The introduction of so-called Learning Journals has proved to be a successful step in this direction. TM is a unique program at Lund University, where a selected number (40) of students from the Faculty of Economics (20) and from the Faculty of Engineering (20) are taught together during their last 2 years of study. Their different views on problems and challenges in today’s industry often complement each other. By the introduction of learning journals, they also learn about themselves, what influence their motivation, behaviour and attitude have on a group, and an understanding of their own preferred learning method. The learning journals are introduced in the course Project Leadership. In this course, the students are divided in groups of 4-5 students, each one managing one project. Throughout the whole course (2 semesters) the students are writing learning journals and supervisors are commenting monthly. The learning journals have four purposes; 1) providing an opportunity to reflect on the development of the project itself 2) enabling personal reflection on the own process, 2) enabling reflection on the own position and part in the group, and 4) through the longitudinal effect of the course,it provides an opportunity to compare journals over time to become aware of and able to analyse the own learning process. In a newly performed Placement report, students that have graduated from the Technology Management programme the last 10 years, rate their education 4.37 out of 5. Some students even consider the Learning Journals among the most valuable parts of the whole programme in retrospect.

Abstract: Economic reflections on the environment are relatively recent: The broader issues of management of scarce resources (oil) or renewable (fisheries) are an even more recent concern, but toward which the public is sensitized, as evidenced the rise of environmental concerns. Although shipping is considered one of the means of transport that causes little harm to the environment, it may have important effects if standards are not observed or are not enforced. Pollution is part of one of the main problems of the environment. All economic transactions; trade, production or consumption by generating mechanical effects of various types of waste: liquid, solid, gaseous are a veritable source of pollution. When these operations generate waste, it is not without environmental impacts. We then speak of "pollution" when environmental assets are degraded and damaged. Economic evaluation of environmental assets, the weathercalculation of damage in disasterwhich are natural origin or resulting from human activity of profits, and damage caused by the implementation of development projects ,have now an important place in public decision making.

Abstract: This paper proposes a new kind of revenue sharing contract for coordinating a three-tier supply chain comprised of a manufacturer, a distributor, and a retailer. The contract requires that the retailer should return partial revenues directly to the distributor and to the manufacturer. A linear model is proposed to determine the parameters of the contract such that channel coordination and a win-win situation can be achieved. We show that any solution within the derived feasible region can achieve the maximum supply chain profit and increase each partner’s profit as well. A numerical example is given to demonstrate the application of the contract.
