In this article, related to a talk given at the International Meeting "Photosynthesis Research for Sustainability-2015", we honor Dr. George C. Papageorgiou, a highly respected scientist and an outstanding teacher and mentor. Praising him for these virtues, indispensable for research sustainability, we also bring to discussion aspects that undermine nowadays both education and research sustainability. We argue that these aspects are principally created by the predominant bureaucratic system, which, by favoring short-term utilitarian orientations and obeying "market laws", jeopardizes university freedom and autonomy, and has turned to "measuring" scientific "production" and establishing accordingly designed funding policies and hiring/firing/promotion criteria, which lead to merit-chasing, grant-hunting, changes in publication practice, and suppression of heterodox ideas. Such system impedes research, creates antagonism, and drives the potentially creative researcher away from originality and discovery, and from the unique satisfaction and benefit that these bring., M.

This paper develops some analytical perspectives for a proper assessment of the dynamics observed on the Hungarian residential property market over the last decade. These dynamics are examined in comparison to official policy objectives. On the one hand, sustainable development and social balance were particularly urgent issues after the last financial crisis. On the other, the residential property market was officially instrumentalised to achieve them. We examined real estate market processes using data from the Hungarian Central Statistical Office and found a change in investment motives and in the main groups of actors dominant in the market, and we also examined the role of foreign investment. At the aggregate national level, the past decade looks like a process of recovery. Nonetheless, the factors relevant for the observable dynamics do not seem to correspond to the goals also formulated in the new constitution, but rather document the investment fever of certain groups.
In this paper, we propose the concept of Suzuki type fuzzy Z-contractive mappings, which is a generalization of Fuzzy Z-contractive mappings initiated in the article [S. Shukla, D. Gopal, W. Sintunavarat, A new class of fuzzy contractive mappings and fixed point theorems, Fuzzy Sets and Systems 350 (2018)85-95]. For this type of contractions suitable conditions are framed to ensure the existence of fixed point in G-complete as well as M-complete fuzzy metric spaces. A comprehensive set of examples are furnished to demonstrate the validity of the obtained results.
