Abstract

Prognozowanie pogody wymaga znajomości praw rządzących ruchem atmosfery. Obok mechaniki płynów trzeba uwzględnić ruch obrotowy naszej planety, zróżnicowane nagrzewanie jej powierzchni wskutek pochłaniania promieniowania słonecznego, a także procesy parowania wody i kondensacji pary wodnej.

Abstract

Even though the discrimination against women in science have been studied for at least half of the century and any many actions have been taken to promote careers of female researchers, their chances are still far from equal. Many barriers have disappeared, but increasingly precarious model of academic career makes it more difficult for women. The interviews conducted with laureates of prestigious competitions by the Foundation for Polish Science allowed for analysis of what Polish researchers think about the role of gender and parenthood in academic career. The have also served to identify factors that were crucial – according to the interviewed female scientists – for their success in science. As the interviews indicate, the requirements od academic career are the same in case of both: men and women, which could suggest lack of discrimination. On the other hand, the expectation that women will be able to meet the criteria set up by male experiences does not mean equal playing field. To assess real chances for academic success, other non-academic aspects of researchers’ life need to be taken into consideration, especially their limitations for dedicating time to research and for mobility. Young researchers – men as well as women – experience increasing uncertainty in regard to their academic future. Growing competition for employment and research funding, makes it much more difficult for women to fulfil the expectations of a fast-track, mobile career. The interviews formed the basis for identification of support mechanisms in this respect.

Abstract

Professor Lech Wojtczak spent his entire scientific life at the Nencki Institute of Experimental Biology PAS, where he worked since 1947. He is the author or co-author of two hundred scientific papers, promoted 15 doctors of science, was the Full Member of PAS and has been awarded with several prizes and honors. Among his students are three successive directors of the Nencki Institute, the authors of the present article. Scientific interests of Professor Lech Wojtczak were always dealing with bioenergectics, a discipline that he led in Poland and Eastern-Central Europe. In particular, his studies focused on the role of fatty acids and their derivatives on bioenergetics, on the regulatory role of surface potential of biomembranes on enzymatic and transport activities, on the regulatory role of calcium and magnesium in mitochondria, on the role of free oxigen radicals in bioenergetics, etc. Apart from being a great scientist, Lech Wojtczak was also a fantastic teacher, and an excellent scientific supervisor. Being well recognized in the world, he was placing members of his research group in foreignlaboratories, as well as was sending tchem to courses and conferences. This was opening their minds to the world, and to other cultures, and allowed Lech Wojtczak to form from his collaborators the next generation of good scientists and future leaders. The list of the most important pupils of Professor Wojtczak is given in the article. Lech was also excellent in social contacts, and in creating a friendly atmosphere. Together with his wife Anna, they kept an open home, often inviting collaborators to parties that usually led to long scientific discussions. With the sudden death of Pofessor Lech Wojtczak Polish science suffered a great loss. This eminent researcher, the father of Polish bioenergetics, but also a warm and modest person, will be dearly missed.

Abstract

The goal of this article is to discuss dynamics hindering women's career in managerial roles of Polish comprehensive universities. Although female academics outnumber their male peers, they remain underrepresented in the management at universities. In the last 30 years, only 2 women held a position of rector. In this article, we analyse the reasons for this phenomenon on the basis of qualitative research performed with the use of individual in-depth interviews, preceded by the analysis of career advancement of individual women. The research has been carried out on a group of 15 women, which currently occupy position of vice-rector or have had position of rector in the past. The results of the analysis show that occupying a position of vice-rector is a key factor determining the chance to obtain a position of rector. This stage of the career helps to consolidate the chosen professional role in the organisation (3 main roles were recognised: expert, researcher and activist). Depending on the type, these roles give greater or lesser opportunities for self-identification in the position of a leader, for adapting to collegial culture of university and as a consequence becoming a rector.

Abstract

The aim of the paper is to show the scale of preparing habilitation reviews ending with untypical conclusions and the impact of such reviews on the outcome of habilitation proceedings in one discipline – sociology. The general analysis of the outcome of the review comes down to the final conclusion; the detailed analysis proposed by the author also takes into account the degree of strengthening or weakening of this conclusion. In particular, the weakening of a positive conclusion may indicate that the actual evaluation of the work is rather negative and differs from the nominal evaluation. The article begins with a theoretical introduction in which the author analyzes the legal aspects of reviewing the achieve­ments to the habilitation degree, the imperfections of this process indicated in the literature, and briefly refers to American and Polish research in the field of pragmatics of RPT reviews, which provide tools to interpret the mechanism of formulating unobvious conclusions. A study conducted on a sample of 130 habi­litation cases in sociology from 2012–2019 showed that the results of the pro-ceedings were rather consistent with the results of the reviews. Nevertheless, a set of “border proceedings” have been identified that have received reviews with a low degree of certainty (weakened) or some, but divergent, degree of certainty. In their case, the outcome of the proceedings was unpredictable, i.e. proceedings with the same review configuration ended in different ways.

Abstract

In this paper we described three Art & Science projects organized by the Nencki Institute of Experimental Biology (Polish Academy of Sciences), Marcel Nencki Foundation for the Support of Biological Sciences and the Art Department of the University of Rzeszów. First project, celebrating the 100th anniversary of the Nencki Institute, was entitled “Biological imaging: inspiration by invisible world” and took place in Mikołajki in 2017. Next two projects were relating to “Art of Biodiversity” (Rzeszów, 2018) and “Power of Biological Structures” (Przeworsk, 2019). The aim of the projects was to introduce ideas of modern experimental biology to artist. All symposia/workshops were followed by few exhibitions at the Nencki Institute of Experimental Biology, Art Department of the University of Rzeszów, etc. Some of paintings originated during these projects established Nencki Art Collection, collection of modern art at Nencki Institute of Experimental Biology.
