Abstract

In the paper I try to demonstrate that interactive concept of metaphor, in particular, that proposed by Ricoeur – contrary to what Wrzosek preaches – has a very limited use in the study of thought processes leading to the formulation of the metaphors used by the science.

Abstract

The paper is a conversation about Wojciech Wrzosek's biography and academic work. It describes his university education at Adam Mickiewicz University, especially his participation in the seminars of Jerzy Topolski and Jerzy Kmita. The paper goes on to outline the subsequent stages of Wrzosek's academic career, his research travels abroad and the leading of the Interdisciplinary History Seminar, which was intended as a continuation of Topolski's seminar. The paper also discusses Wrzosek's two books – History – Culture – Metaphor and On Historical Thinking – their intellectual genealogy, context of their writing and reception.

Abstract

Failures that occurred in the last few decades highlighted the need to raise awareness about the emergent risk related to the impact localised degradation phenomena have on embankments. Common interventions aimed to improve embankments, such as the reconstruction of the damaged area or the injection of low-pressure grouts to fill fractures and burrows, may cause the weakening of the structure due to discontinuities between natural and treated zones. Moreover, since such repair techniques require huge volumes of materials, more sustainable solutions are encouraged. At the same time, the textile and fashion industries are looking for sustainable waste management and disposal strategies to face environmental problems concerned with the voluminous textile waste dispatched to landfills or incinerators. The use of soil mixed with textile waste in embankment improvement has been investigated to identify an effective engineering practice and to provide a strategy for the circular economy of textiles. Preliminary laboratory tests have been conducted on soil specimens collected from the Secchia River embankment, Northern Italy, to define the appropriate mixture proportions and to compare physical properties and hydro-mechanical behaviour of natural and treated soils. The results show that an appropriate fibre content offers manageable and relatively homogeneous mixtures. The indluence on soil consistency is mainly due to the textile fibre hydrophilic nature. The addition of fibres reduces the maximum dry density and increases the optimum water content. At low stress levels, the compressibility and hydraulic conductivity appear higher, however macro voids produced during sample preparation may alter the findings.

Abstract

This paper outlines effect of the mix composition on mechanical properties of high–strength concrete based on aggregate size like in of Reactive Powder Concrete (RPC) but without fiber reinforcement. The main purpose which guided the authors choosing proportion of water and superplasticizer (SP) was to achieve a similar consistency in the test slump for various concrete mix. Test results for 3 groups of superplasticizers, designated as D – with chemical base – acrylic polymer, V – with chemical base – polycarboxylate ether, P – with chemical base – modified polycarboxylates, two cement groups, designated as Cem A – with fineness Blaine 3980 cm 2/g, Cem B – with fineness Blaine 4430 cm 2/g and 2 types of aggregate: basalt and granite were presented. After curing for 1, 7 and 28 days samples were tested for compressive strength and flexural tensile strength. The article also presents the study of the elemental composition and structure of the SP with the use of the SEM electron microscope. The amount of solid particles in the SP was also determined by the water vaporization. The assumption of the paper was to maintain the consistency of the mixture at the S2 level according to the Eurocode standard. The paper proposes a method based on SEM analysis in order to select a superplasticizer with the best ductility parameters, and the best results of the compressive and flexural tensile strength of concrete samples were obtained. The best results for compressive strength after 28 days are obtained for concrete series with the polycarboxylate ether superplasticizer and modified polycarboxylate ether superplasticizer in combination with the use of type A cement and it is greater than for the concrete series with type B cement by 11.7%.

Abstract

This paper presents a review of composite structures in which aluminium alloys are used. Current trends in the research of composite structures with aluminium girders and their possible applications in structural engineering were shown. In the presented solutions, advantageous properties of aluminium alloys were exploited, such as high strength-to-weight ratio, corrosion resistance and recyclability. The authors demonstrated the structural behaviour of aluminium-concrete and aluminiumtimber composite beams based on their own tests as well as investigations presented in the literature. Furthermore, aluminium-concrete composite columns, a composite mullion made of an aluminium alloy and timber, and a military bridge consisting of aluminium truss components, a stay-in-place-form, reinforcement and concrete were presented. In addition to the description of the structural elements, the main conclusions from their experimental, theoretical and numerical analyses were also demonstrated in this paper. The connection of aluminium girders with concrete or timber slabs provided for the increase of the load-bearing capacity and stiffness, and it eliminated the problem of local buckling in girder flanges and lateral-torsional buckling of girders in the analysed solutions.

Abstract

In the first years of the Kingdom of Serbs, Croats, and Slovenes, the foundations were laid for a political crisis that later marked its entire existence until its collapse at the outset of World War II. One of the basic causes for this situation was the centralist policy implemented by the dominant political actors, despite the complexities and heterogeneity of the new state. This study analyses the direction and tempo with which this centralist system was built from 1918 to 1923, with a focus on the western regions which had been a part of the Austro‑Hungarian Empire until 1918, and whose political representatives most strongly opposed centralisation.

Abstract

The aim of this article is to take a closer look at school communities in the Polish‑Ukrainian borderland in the 1918/1919 school year. Their members, particularly the headteachers, previously focused on teaching the students obedience and loyalty towards the emperor in Vienna, had to completely redefine their roles in order to find themselves in the new reality in the late autumn of 1918. Moreover, another year of the turmoil of war, countless teachers and students in the army, enormous economic problems, exacerbated by the fights for dominance on the disputed territory, forced the headteachers to deal with matters as they arose, and the decisions they made did not always work in practice. What cast a shadow over secondary school activity apart from the Polish‑Ukrainian war was also Polish‑Jewish relations.

Abstract

This paper investigates the situation of Galician refugees in the Habsburg Empire during the last year of the First World War. The majority of the refugees returned home following the eastward movement of the frontline in 1915 (i.e. after the Gorlice‑Tarnów campaign). However, many others stayed deep within the Austro‑Hungarian Empire till the end of the war. According to the official reports of the Ministry of the Interior, there were still 90 thousand refugees (25% Poles, 28% Jews, and 46% Ukrainians, then known as Ruthenians) receiving social benefits from the state in the Austrian part of the Empire on 1st September 1918. Moreover, one can add countless refugees who stayed in the interior of the Empire at their own expense. The situation became even more complicated when the feelings of enmity on the part of the local inhabitants escalated. Pressed by society, the local authorities started expelling the refugees. As a consequence, some of them returned home, while others still stayed in exile in search of a better life. What is even more interesting is that some of them (mostly Jews) emphasised the lack of a bond with the new Polish state born in November 1918.

Abstract

The incarceration of those determined to be security risks was a common feature of the wartime regimes of most European belligerents throughout the Great War. Yet, especially in several of the Habsburg successor states, internment and politicised incarceration continued as the war morphed into smaller wars, revolutions, and counterrevolutions. This paper traces the social history of political incarceration in Hungary between approximately 1914–1924, with special attention to the post‑armistice period, during which wartime emergency laws were extended or revised to deal with political upheaval and renewed regional warfare. Within this framework, the paper focuses on the experience of one woman, a university‑educated teacher, who became a leading leftist educator and was imprisoned for her role in the Hungarian Republic of Councils (also called the Hungarian Soviet Republic) in 1920. She left Hungary for the Soviet Union in the 1920s as part of a prisoner exchange, and she remained there until the end of World War Two. She later returned to Hungary, and in 1953, published a memoir about her experiences during World War One and its aftermath. Using a gendered analysis to move from the larger context to the individual experience helps reveal continuity and change from Hungary’s Great War to its “war after war,” as well as the systematic and improvised nature of carceral deprivation and violence against female political prisoners. It also shows how the gendered memories of the Long World War One inflected the post‑1945 socialist party’s ideological mobilisation of women, putting forward an example of socialist womanhood that simultaneously challenged and reinforced the categories of prisoners and activists.

Abstract

The independence of newly born (or reborn) states at the end of 1918 raised the question of the future of the aristocratic families who had built their position in the pre‑war empires. An interesting example of such dilemmas arose in Poland. This was connected with the fate of two originally German‑speaking families. One of them was a branch of the imperial Habsburg family that settled in Żywiec (German: Saybush) in western Galicia. The other: rich and powerful family of Hofburg von Pless having their main seat in Pszczyna (German: Pless) in Prussian Upper Silesia. They were both members of the absolute elite of European aristocracy, being related to many noble and royal families and playing important roles in the political and economic life of Austro‑Hungary and Germany. What they also had in common was the fact, that their estates were located in a borderland between different ethnic and national groups. After the end of World War One, almost all these properties became part of the independent Polish state. As a result, the new administration treated the families with serious distrust. However, their national choices were different: the Habsburgs of Żywiec started to consider themselves as pure Polish, while the Hofburgs radically adhered to their German self‑identity. This article shows what the criteria were behind these choices.

Abstract

The Vistula Pomeranian (the former Prussian province of West Prussia) remained the longest dependent part of the partitioning power of Poland, which was reborn after 1918. In the second half of the nineteenth century, the Polish population of these lands, whose original ethnic component was Kashubians, strengthened their national awareness under the influence of modernisation processes. As in the entire Prussian partition, the dominant factor here was the idea of national solidarity built around an attachment to Catholicism. The defeat of Germany in World War I was associated by the local Poles with the incorporation of Pomeranian lands into the borders of the Polish Republic. The decisions of the Paris Conference of 1919 were awaited with hope and enthusiasm. Independence, however, brought disappointment caused by the economic crisis, as well as the inability of the central authorities to deal with the native population. Against this background, there were conflicts and misunderstandings throughout the entire interwar period. After 1920, the slogans of regional particularism gained popularity among the indigenous Pomeranian population. However, the German threat of the yoke forced local political and social activists to respond to the idea of unification of Pomeranian lands with the rest of the country, pushed by the central authorities.

Abstract

This paper examines how Latvian communities abroad reacted to and were influenced by a change of the first magnitude in the political life of their homeland, namely, the proclamation of the Republic of Latvia on November 18, 1918. News of the proclamation, first of all, necessitated diaspora Latvians choosing attitudes towards the new phenomenon, which highlighted the political pre‑dispositions of the different groups within the diaspora. Polarisation of opinions was followed shortly by a wave of activities both in support of and against the new Republic. These activities included gathering financial resources for war victims and state institutions in Latvia, public relations campaigns in diaspora host countries, political lobbying etc. The establishment of the Republic of Latvia also profoundly influenced and intensified the internal formation processes within the diaspora. A marked increase of activity is observable in all fields of engagement that are characteristic of an active ethno‑national diaspora: the internal organisational structure was further developed; contacts with the homeland intensified; mutual links between geographically distant diaspora groups became closer. The great political changes in the homeland gave the Latvian diaspora the push necessary to fully develop and become an active ethno‑national diaspora.
