Social inclusion by revitalisation? The potential of disused industrial areas as an opportunity for mitigating social polarisation

The paper concerns the relation between revitalisation projects and socio-economic polarisation, and discusses the potential of new urban spaces for social inclusion. The phenomenon is considered on the example of recreational facilities that have emerged from brownfields located in the Ruhr region (Germany). It was ascertained that the diversity of implemented projects was important in terms of the significance of revitalisation processes for social polarisation tendencies. It allowed regional authorities to create income-generating facilities and spaces that can be used regardless of income, and to resolve deficits in urban recreational facilities. It was also noted that the Ruhr examples could provide guidance for the recently begun revitalisation processes in the Upper Silesian industrial area (Poland)

Revitalisation for everybody? The Landscape Park Duisburg–North

Park Krajobrazowy Duisburg Północ jest jednym z najbardziej znanych projektów rewitalizacyjnych w Zagłębiu Ruhry. Jego realizacja rozpoczęła się w 1985 roku na terenie dawnej huty żelaza. Unikatowy charakter tego obiektu jest wynikiem połączenia pełnionych przez niego funkcji: z jednej strony jest to reprezentacyjne dla regionu Ruhry miejsce organizacji różnego rodzaju imprez oraz atrakcja turystyczna, z drugiej zaś strony park służy codziennej aktywności rekreacyjnej lokalnej społeczności. Możliwość uprawiania w jednym miejscu sportu, rekreacji, kultury i turystyki zdaje się być udanym połączeniem, a różne funkcje parku nie zakłócają się wzajemnie. W przeciwieństwie do Parku Krajobrazowego Duis-burg Północ, który łączy (przynajmniej przestrzennie) ludzi o różnych zainteresowaniach niezależnie od statusu spo-łecznego, inne duże projekty rewitalizacyjne w Zagłębiu Ruhry, zwłaszcza obiekty rozrywkowe i rekreacyjne, jak kryte stoki narciarskie lub parki rozrywki, często są bardzo drogie i przez to niedostępne dla wszystkich, co z kolei może intensyfikować trendy polaryzacji społecznej

Algorithmic discrimination in employment : an overview

Debates about the future of work in light of developments in artificial intelligence are held predominantly in the context of job losses and technological unemployment. Far less attention is paid to the challenges posed by the increasingly widespread phenomenon of algorithmisation of management functions in the modern world of work. Meanwhile, the shift to algorithmic management represents a significant qualitative change that, in addition to promising broadly understood modernisation and optimisation of decision-making processes, carries specific repercussions in the context of human rights protection, including in particular the prohibition of discrimination in employment. The article attempts to assess the adequacy of the EU antidiscrimination instrumentarium to the specifics of algorithmic discrimination mechanisms, and aims to encourage an in-depth scientific discussion on the need to develop effective regulatory responses at the national level

The Mathematical Legacy of Andrzej Lasota

Professor Andrzej Lasota (1932–2006) was a Polish mathematician with wide ranging interests in dynamical systems, probability theory and ergodic theory who saw the inter-relationships between all three and who successfully synthesized these apparently disparate fields. He used that synthesis to both further mathematical research as well as to investigate problems in biology. One of his over-riding interests was the way in which seemingly “random” or “probabilistic” processes (in a mathematical sense) could actually be thought of as equivalently coming from deterministic dynamics. How did we each come to know him and his work? Michael C. Mackey met Lasota in Cracow in 1977 through his collaborator Dr. MariaWazewska-Czyzewska, a hematologist and daughter of Professor Tadeusz Wazewski. That meeting blossomed into an almost 30-year-long friendship and collaboration in biomathematics. Marta Tyran-Kaminska met Lasota during her mathematical studies at the University of Silesia in Katowice in 1992 and did her Ph.D. under his supervision. Hans-Otto Walther met Lasota during a year at Michigan State University, 1979–1980, where Pavel Brunovský was also visiting, and they had all been brought together by Shui-Nee Chow

History Learning Innovation with Steam Approach

So far, history lessons are only textual in nature. For this reason, teachers must start preparing students to face the rapidly changing technological developments. Meanwhile, the need for human resources in the future is to be able to think analytically, collaboratively, and interdisciplinary. For this reason, this research will raise the application of STEAM through Project Based Learning as an innovation in learning history. Researchers use qualitative methods. First, reflection aims to bring students into the context of the problem and provide inspiration to students. At the research stage, more learning processes occur. In this stage, the teacher also guides the discussion more and determines whether students have developed conceptual and relevant understanding. The discovery stage connects research and information known in project preparation. Students begin to study independently and determine what is still unknown. At this stage, the students collaborate to find solutions. At the application stage, students test products made from previously determined conditions. The results obtained are used to improve the previous step. The final step is communication. The communication process is carried out to convey ideas. At this stage, the teacher and colleagues conduct a final assessment. In addition, teachers are also expected to be able to provide appreciation and constructive feedback. The results showed that STEAM in Project Based Learning for history learning proved to be effective in encouraging students' creativity, collaboration, and communication skills. However, this method requires careful planning. Some students are also not familiar with project learning

Uniwersalizm postanowień Europejskiego Filaru Praw Socjalnych w zakresie sprawiedliwych warunków pracy - realny kierunek zmian czy fantasmagoria? Zagadnienia wybrane

Europejski Filar Praw Socjalnych koncentruje szereg swoich regulacji wokół uczciwychwarunków zatrudnienia. Dotychczasowy dorobek prawodawstwa unijnego gwarantowałwiele praw w tym zakresie, nie wydaje się jednak, aby ich realizacja była wystarczająca.W świetle powyższego zasadne staje się zidentyfikowanie wyzwań stojących przedprawodawcą unijnym jak i krajowym w kontekście zabezpieczenia stosownego poziomuuczciwych warunków zatrudnienia.A wide range of regulations of the European Pillar of Social Rights are focused on fair employment conditions. The hitherto achievements of EU legislationguaranteed a number of rights in this respect, yet their implementation still appears insufficient. In the light of the above, it is justified to identify the challenges that the EU and national legislator are facing in the context of securing an adequatelevel of fair employment conditions

Revitalisation of spoil tips and socio-economic polarisation – a case study of Ruhr area (Germany)

The paper discusses issues about the revitalisation of spoil tips, socio-economic polarisation and social exclusion in the field of municipal recreational activities based on an example of the largest post-industrial region in Europe – the Ruhr area in Germany. Revitalisation of brownfield areas very often leads to the creation of leisure facilities of various types (with a range of entrance fees) and because of this it may mitigate, or exacerbate, the severity of these negative phenomena. In the Ruhr area there are 104 spoil tips of different origins (mine tips, slag heaps, rubbish dumps), sizes and shapes (from conical heaps, through table mountains shaped tips and intentionally shaped for landscape tips, to major tips) and state of preservation. The research has shown that it is possible to use the majority of these spoil tips in the Ruhr area (87 of them) as leisure facilities as they have been changed into green areas, parks, playgrounds, locations for sports activities and tourist attractions after their restoration. Furthermore, they are mostly accessible free of charge and may serve a wide range of people – from locals to visitors, from children to senior citizens etc., regardless of their income. As such they may mitigate the socio-economic polarisation tendencies in the region

Differential distribution of the wlaN and cgtB genes, Associated with Guillain-Barré Syndrome, in Campylobacter jejuni isolates from humans, broiler chickens, and wild birds

Campylobacter jejuni causes campylobacteriosis, a bacterial gastroenteritis with high incidence worldwide. Moreover, C. jejuni infection can trigger the polyneuropathic disorder denominated Guillain-Barré syndrome (GBS). The C. jejuni strains that can elicit GBS carry either wlaN or cgtB, coding both genes for a β-1,3-galactosyltransferase enzyme that is required for the production of sialylated lipooligosaccharide (LOSSIAL). We described a differential prevalence of the genes wlaN and cgtB in C. jejuni isolates from three different ecological niches: humans, broiler chickens, and wild birds. The distribution of both genes, which is similar between broiler chicken and human isolates and distinct when compared to the wild bird isolates, suggests a host-dependent distribution. Moreover, the prevalence of the wlaN and cgtB genes seems to be restricted to some clonal complexes. Gene sequencing identified the presence of new variants of the G- homopolymeric tract within the wlaN gene. Furthermore, we detected two variants of a G rich region within the cgtB gene, suggesting that, similarly to wlaN, the G-tract in the cgtB gene mediates the phase variation control of cgtB expression. Caco-2 cell invasion assays indicate that there is no evident correlation between the production of LOSSIAL and the ability to invade eukaryotic cells.info:eu-repo/semantics/publishedVersio

Oxidative Stress and Digestive Enzyme Activity of Flatfish Larvae in a Changing Ocean

Until now, it is not known how the antioxidant and digestive enzymatic machinery of fish early life stages will change with the combined effects of future ocean acidification and warming. Here we show that high pCO2 (~1600 μatm) significantly decreased metabolic rates (up to 27.4 %) of flatfish larvae, Solea senegalensis, at both present (18 °C) and warmer temperatures (+4 °C). Moreover, both warming and hypercapnia increased the heat shock response and the activity of antioxidant enzymes, namely catalase (CAT) and glutathione S-transferase (GST), mainly in post-metamorphic larvae (30 dph). The lack of changes in the activity of CAT and GST of pre-metamorphic larvae (10 dph) seems to indicate that earlier stages lack a fully-developed antioxidant defense system. Nevertheless, the heat shock and antioxidant responses of post-metamorphic larvae were not enough to avoid the peroxidative damage, which was greatly increased under future environmental conditions. Digestive enzymatic activity of S. senegalensis larvae was also affected by future predictions. Hypercapnic conditions led to a decrease in the activity of digestive enzymes, both pancreatic (up to 26.1 % for trypsin and 74.5 % for amylase) and intestinal enzymes (up to 36.1 % for alkaline phosphatase) in post-metamorphic larvae. Moreover, the impact of ocean acidification and warming on some of these physiological and biochemical variables (namely, lower OCR and higher HSP and MDA levels) were translated into larvae performance, being significantly correlated with decreased larval growth and survival or increased incidence of skeletal deformities. The increased vulnerability of flatfish early life stages under future ocean conditions is expected to potentially determine recruitment and population dynamics in marine ecosystems.info:eu-repo/semantics/publishedVersio
