Geopoetycki głos krajobrazu postkolonialnego. Obraz miejsca autobiograficznego w twórczości Tarasa Prochaśki
Authors: Ursulenko Anna
Published: March 2020

Geopolitical voice of the postcolonial landscape. The image of an autobiographical space in the works of Taras Prokhasko The aim of the article is to analyze the components of the autobiographical space, which can be found in Taras Prokhasko’s essay Discours de cosaques, with particular reference to the categories of space, memory, and trauma. The author will explore how Prokhasko builds a relationship between memory and space in the context of identity formation strategies that place this text in the geophysical creation of a Place. Taking into consideration the postcolonial approach will allow the author to look at the essay as a realization of the author’s strategy, part of which fits into the postcolonial discourse of Ukrainian literature and, more broadly, the literature of Central and Eastern Europe. The author will focus on Prokhasko’s recognition of the provincial motif closely linked to the national perspective.Геопоэтический голос постколониального ландшафта. Образ автобиографического места в творчестве Тараса ПрохаськоЦелью статьи является анализ компонентов автобиографического места, образ которого представлен в эссе Discours de cosaques Т. Прохасько.

The European Parliament and the negotiation of the Multiannual Financial Framework
Authors: Grosse Tomasz Grzegorz
Published: March 2020

The paper examines the role of the European Parliament in the process of adopting the MFF for 2014–2020. Th is particular case is attention-worthy for at least two reasons: firstly, it demonstrates the actual political role of the EP in relation to fiscal policy, where this institution’s power is much weaker than in other regulatory matters. Secondly, it illustrates the role of the EP during a period of economic crisis, and therefore at a time when the impact of the intergovernmental factor on European policy was much increased. In doing so, the author will verify three hypotheses. The first is that although the legislative competences of the EP are rising steadily, this does not mean that the relative power of this institution is also on the ascent, i.e. to a comparison with intergovernmental institutions. Secondly, the author is to consider whether the activity of the EP is not primarily used for the purposes of political legitimisation and marketing. Thirdly, he is to verify the claim that the EP is a platform for the development of supranational elites.Parlament Europejski a negocjacje nad Wieloletnią Perspektywą FinansowąCelem artykułu jest analiza roli Parlamentu Europejskiego PE w procesie stanowienia Wieloletnich Ram Finansowych na lata 2014-2020. Autor podejmuje próbę weryfikacji trzech hipotez, które niekiedy występują w literaturze dotyczącej parlamentaryzmu europejskiego. Po pierwsze, wprawdzie kompetencje ustawodawcze PE systematycznie rosną, jednak nie oznacza to, że wzrasta władza polityczna tej instytucji w UE. Dotyczy to zwłaszcza władzy względnej, a więc w odniesieniu do tej, jaką dysponują instytucje międzyrządowe. Po drugie, aktywność PE służy przede wszystkim celom legitymizacyjnym w UE. Po trzecie, PE jest platformą dla rozwoju elit europejskich lub ponadnarodowych.
Rola kategorii równości w modelu społecznych relacji komunikacyjnych Jürgena Habermasa
Authors: Jakubowski Radosław
Published: March 2020

Model społecznych relacji komunikacyjnych skonstruowany przez Jürgena Habermasa stanowi podstawę jego teorii prawowicie legitymizowanej władzy politycznej. Kluczową rolę w tym modelu odgrywa kategoria równości, która gwarantuje inkluzję i dostęp obywateli do obiegów komunikacyjnych, będących podwaliną sfery publicznej. Z działań komunikacyjnych Habermas wyprowadza również dyskursywną koncepcję stanowienia prawa, której istotę także stanowi kategoria równości. Zinstytucjonalizowanie zasady równości poprzez medium prawa zapewnia bowiem komunikacyjną reprodukcję mechanizmu demokratycznego. Jest to możliwe dzięki aktywnemu w sferze publicznej społeczeństwu obywatelskiemu, którego działania komunikacyjne nieustannie przekładają się na proces stanowienia prawa odpowiadającego bieżącym potrzebom społecznym.The role of category of equality in Habermas’s model of social communicative relationsHabermas’s model of social communicative relations creates the ground for his theory of legitimized political power with the category of equality as its key component. Category of equality guarantees citizens inclusion and access to communication circuit which constitutes the ground for public dialogue in sphere of communicative actions. Habermas brings out also a discursive concept of law-making as its substance also lies in category of equality. The institutionalization of the equality rule through the law ensures communicative reproduction of democratic mechanism. That is possible by dint of civil society active in public sphere and its communicative activities which invariably transfer to the law-making process meeting the current social needs.

Approaches to Writing a Social History of Dutch in Japan
Authors: Joby Chris
Published: March 2020

To date there has been no social history of the interesting subject of the Dutch language in Japan from c.1600 to 1900. This article provides a brief introduction to the use of Dutch in Japan, and then considers three possible approaches to writing such a history, evaluating the merits of each approach. The first of these is to analyse the use of Dutch in Japan by communities of language. The second approach is domain-based. This approach considers the use of language within social domains or spheres of activity, such as commerce and education. The third approach is a function-based one, which focusses on the purposes for which individuals and groups used Dutch. These include functions such as translation and interpretation. The article concludes that given the particularity of the use of Dutch in Japan, it may be better to use aspects of each approach in writing a social history on this subject.
Mits wroeginge der conscientien: het voorwaardelijk voorzetsel ‘mits’ al in de zestiende eeuw
Authors: Loosen Gert
Published: March 2020

Mits wroeginge der conscientien: het voorwaardelijk voorzetsel ‘mits’ al in de zestiende eeuw The old Dutch mits ‘if and only if’ seems to experience a revival in usage: conjunction, preposi­tion, autonomous, elliptical. In this article we analyse two participle constructions, one old Bible verse translated into Dutch in the 16th century, one over 200 year old French sentence about spara­grass, translated in a Flemish newspaper in 2016. Mits seems to come in handy to steer the meaning of participle constructions, which aren’t that common anymore in contemporary Dutch. Here, too, the ‘semantic regularity’ in ‘mits’-constructions Daalder wrote about, is kept intact.
Huygens: lost – regained – revised. De literair-historische receptie van Constantijn Huygens in de eerste helft van de 19e eeuw

Huygens: lost ‒ regained ‒ revised. De literair-historische receptievan Constantijn Huygens in de eerste helftvan de 19e eeuwFrom the beginning of professional Dutch Studies M. Siegenbeek’s inauguration as professor elo­quentiae hollandicae extraordinarius, 1797 the 17th century Dutch writers P.C. Hooft and Joost van den Vondel are present in Dutch literary studies and literary historiography. The position of ConstantijnHuygens, whom the contemporary literary scholars also include in the Grote Vijf Great Five of the 17th-century Dutch literature besides Vondel, Hooft, Cats and Bredero, was gradually changing dur­ing the 19th century. This article postulates that the reception of Huygens in literary historiography of the first half of the 19th century can be divided into three phases. In the first phase Huygens’ works practically disappeared from the Dutch literary landscape. The second phase encompasses growing interest for Huygens as an important historical figure. In the third phase it is possible to observe a shift in critical reception of Huygens: from Huygens as a historical person to Huygens as a poet.

Latent Heat Thermal Energy Storage (LHTES) is the method to store thermal energy by changing the phase of Phase Change Material (PCM). This method is being developed to store heat loss for increasing energy efficiency. In this paper, the effect of variation flow rate on the melting characteristics PCM was investigated by three-dimensional numerical simulation using ANSYS FLUENT 17. The set-up of this research was carried out on concentrically two cylindrical tubes with diameter outer tube 10 cm and length 60 cm while diameter inner tube 5 cm and length 50 cm. The inner tube is used as a PCM container and the outer tube which has bottom and top hole is used as Heat Transfer Fluid (HTF) circulation. Variation HTF or hot water flowrate was carried out by 4L / min, 8L / min and 12 L / min while the temperature is kept at 75oC, then flowed through bottom hole and out to top hole. From this study it was found that the variation flow rate did not have significant effect on the melting pattern, only the greater flow rate, the smaller melting time. Natural convection is the main role of heat transfer when melting.

HHO gas is an alternative energy that can replace fossil energy sources. HHO gas itself can be produced in several ways, one of which uses water electrolysis. Water is given a direct electric charge so that the water molecule (H2O) splits into HHO gas. This study aims to determine the effect of iron plate electrode distance on the productivity and efficiency of HHO generator by varying it from 2 mm, 4 mm and 6 mm, for the water used is the sea water of Teluk Tamiang Village which was dissolved together with KOH of 3,04%. From the experiments carried out the data obtained in the form of voltage, current, time to produce 50 ml of HHO gas, pH of sea water, pH of the solution before and after electrolysis, and temperature after electrolysis. The data is then processed so that it gets the highest productivity at a distance of 2 mm with an average flow rate of 0,89 ml/s and the highest efficiency at a distance of 2 mm with an average of 23,83%. This is because at a distance of 2 mm the electrons move from the cathode electrode to the anode electrode faster and the resulting resistance is smaller, so that the HHO generator produces faster oxyhydrogen bubbles and less power and energy consumption.

A More Proximate Form of Theory: Tracing New Interdisciplinary Ground through Discourses of Diaspora and Haptic Aesthetics
Authors: Birch-Bayley Nicole
Published: March 2020

Cultural geographers Nigel Thrift and Stephen Pile have asked, “how is it possible to make sense of our selves, if the boundaries that tell us who ‘we’ are are incoherent, or fragmented, or fuzzy[?]” (1995: 179). One promising answer to this question has been to deconstruct the otherwise stable sense of identity that has marked the body in discourses of culture and transnational geography. The emerging interdisciplinary field of haptics (referring to the study of the sense of touch) offers a new way of investigating the boundaries that mark the body in the contexts of culture and literature, specifically exploring who is touched, who touches, when touch begins, and when it ends, in order to creatively examine boundaries of culture, which although fragmented, shifting, topographically uneven, offer unique and productive ways of re-conceptualizing transnational identity. Tracing the expanding the field of haptics to the discourses of diaspora and cultural studies, this paper will discuss haptic aesthetics in the shifting terrain of cultural studies and diasporic theory, for what this emerging field suggests about the incoherent nature of cultural boundaries and alternative possibilities for transnational community formation.
Complexes of Tournaments, Directionality Filtrations and Persistent Homology
Authors: Levi Ran , Govc Dejan , Smith Jason
Published: March 2020

Complete digraphs are referred to in the combinatorics literature as tournaments. We consider a family of semi-simplicial complexes, that we refer to as ``tournaplexes'', whose simplices are tournaments. In particular, given a digraph G, we associate with it a ``flag tournaplex'' which is a tournaplex containing the directed flag complex of G, but also the geometric realisation of cliques that are not directed. We define several types of filtrations on tournaplexes, and exploiting persistent homology, we observe that flag tournaplexes provide finer means of distinguishing graph dynamics than the directed flag complex. We then demonstrate the power of these ideas by applying them to graph data arising from the Blue Brain Project's digital reconstruction of a rat's neocortex.

3M syndrome is a rare disorder that involves the gene CUL7. CUL7 modulates odour detection, conditions the olfactory response (OR) and plays a role in olfactory system development. Despite this involvement, there are no direct studies on olfactory functional effects in 3M syndrome. The purpose of the present work was to analyse the cortical OR, through chemosensory event-related potentials (CSERP) and power spectra calculated by electroencephalogram (EEG) signals recorded in 3M infants: two twins (3M-N) and an additional subject (3M-O). The results suggest that olfactory processing is diversified. Comparison of N1 and LPC components indicated substantial differences in 3M syndrome that may be a consequence of a modified olfactory processing pattern. Moreover, the presence of delta rhythms in 3M-O and 3M-N clearly indicates their involvement with OR, since the delta rhythm is closely connected to chemosensory perception, in particular to olfactory perception.
FAIR Digital Objects for Science: From Data Pieces to Actionable Knowledge Units
Authors: De Smedt Koenraad , Koureas Dimitris , Wittenburg Peter
Published: March 2020

Data science is facing the following major challenges: (1) developing scalable cross-disciplinary capabilities, (2) dealing with the increasing data volumes and their inherent complexity, (3) building tools that help to build trust, (4) creating mechanisms to efficiently operate in the domain of scientific assertions, (5) turning data into actionable knowledge units and (6) promoting data interoperability. As a way to overcome these challenges, we further develop the proposals by early Internet pioneers for Digital Objects as encapsulations of data and metadata made accessible by persistent identifiers. In the past decade, this concept was revisited by various groups within the Research Data Alliance and put in the context of the FAIR Guiding Principles for findable, accessible, interoperable and reusable data. The basic components of a FAIR Digital Object (FDO) as a self-contained, typed, machine-actionable data package are explained. A survey of use cases has indicated the growing interest of research communities in FDO solutions. We conclude that the FDO concept has the potential to act as the interoperable federative core of a hyperinfrastructure initiative such as the European Open Science Cloud (EOSC).
