Abstract This study explores the depictions of landscapes and emotions in the ninth-century hagiographies associated with Liudger: the three vitae Liudgeri and Liudger’s own vita Gregorii. The Frisian missionary founded the monastery of Werden, situated near the Frankish-Saxon frontier. It will be argued that previous historiography on early medieval frontiers has predominantly focused on the military nature of frontiers. Here, more cultural or symbolic natures of the Frankish-Saxon frontier will be discussed. The hagiographical narratives will be examined in conjunction with the notion of a frontier as a ‘third space’. The vitae Liudgeri shaped a discourse that legitimated Liudger’s translation to Werden. This resulted in the creation of a new place of Christian worship in the competitive landscape of post-conquest Saxony, as part of the Christianization of the region. Monasteries like Werden were the places where new missionaries were educated who would continue this Christianization. Exemplary emotional behaviour of the saints, narrated in hagiographies, could help instruct this new generation. Altfrid and Liudger tried to dissuade emotions of anger, indicated by ira or furor, with their hagiographical narratives. These two perspectives offer a glimpse into the attempts of a local monastery to stand out in the Frankish-Saxon frontier.

The time limits of the life of one generation are about 25-30 years, so lived in the struggle for building its own state and its armed defence, this time for Ukraine goes down in the history of the first generation of creation and attempts to comply with four military doctrines (1993-2004-2012-2015), in which our own defence course was proclaimed. The theoretical basis of these official documents of significance were certain paradigms of military-political thinking, according to which Ukraine did not consider it a continuation of politics. The direction and principles of military policy (defence or security policy in European terminology) for modern Ukraine from the mid-20s of the XIX century, as well as 100 years ago, again came to the fore in connection with the implementation of previously abstract concepts " annexation "," occupation "," war ", which allegedly did not exist for our country in recent history. But today they have been embodied or, in the image of Franz Kafka, "reincarnated" into threatening forms of Russia's military practice against our state, the end of which is not yet visible in the near future. The military-theoretical and political response was the "Military Strategy of Ukraine" in 2021, which "opened" a new generation of paradigms of militarypolitical thinking. The main thesis is the belief that the protection of sovereignty and strengthening of military security is the military-theoretical and political response was the "Military Strategy of Ukraine" in 2021, which "opened" a new generation of paradigms of military-political thinking. The main thesis is the belief that the protection of sovereignty and strengthening of military security is the creation of a "comprehensive defence system" with the integration of all forces of the state and civil society, law enforcement agencies and volunteers, administrative regions and territorial communities. The military-theoretical and political response was the "Military Strategy of Ukraine" in 2021, which "opened" a new generation of paradigms of military-political thinking. We will prove that this is a philosophy of military security instead of the previously expressed doctrinal military-political ideas of entrusting a matter of national importance to the forces of the defence sector. The new generation of public life Ukraine will begin with a new paradigm of militarypolitical thinking, the central idea of which is the transition from hopes for the political levers of defence for international cooperation to the creation of a system of comprehensive national security with the synergistic potential of Ukrainianity.

The specific conditions peculiar to the Northern regions create a number of difficulties in the functioning of the information airfield structure based on the traditional complex of navigation aids. These difficulties are caused by the unstable operation of satellite navigation systems in the Arctic region and territorial fragmentation. There is an urgent need to develop new approaches and technical means for the deployment of local navigation systems that ensure the operation of airfields with low traffic and difficult flight conditions. The aim of the study is to develop approaches to the creation of a new generation of multifunctional radar systems for the organization of a local navigation and information system at the airfields of the Arctic region, consisting of a ground-based multifunctional station, a portable small-sized terminal installed on board the aircraft and a board-to-ground communication line. This article proposes a promising navigation and territorial system for Arctic airfields, based on a new generation of information tools, including multifunctional radar stations. The proposed local territorial navigation and system is based on the information of the ground-based multifunctional airfield control radar. The information is transmitted to a portable small-sized terminal installed on board the aircraft. In this system, when transmitting the current situation to the on-board terminal from the multifunctional radar, which is linked to the airfield control center, it provides a safer implementation of the approach and landing modes at Arctic airfields, including in the complete absence of satellite navigation. The implementation of the proposed principles and technical solutions will enable the creation of a new generation of technical tools and the introduction of new organizational approaches to the creation of local navigation systems.

Our economies and societies are changing, with significant effects on each individual, as they have to cope with increasingly complex and unpredictable working lives. Therefore, innovative digital learning applications that respond to their end user's needs and desires become inevitable. Whilst relying on user-centered design structures, the participatory design methodology provides a promising approach towards the creation of such a new generation of digital learning applications. After thoroughly outlining the research undertaking's rationale and following to a theoretical discussion, the author gives insights into the results of problem-centered interviews with digital learning and user experience experts that build the basis for the creation for a prototypical participatory design process. These findings primarily confirm the recent literature and provide, complemented by the created process, a sound basis for further theory-oriented, scientific discussions but application in practice as well.

An authoring system is a key computer tool for facilitating the creation of instructional lessons (courseware) for the computer. While authoring systems have been around for many years, few if any have had both the flexibility and power needed to create sophisticated instructional materials. This article describes what is meant by an authoring system, and why educators should consider using one. The specifications for what we believe is a new generation of authoring system is then presented, with a detailed description of the capabilities which should be included. Finally, we present the results of our efforts in creating and using an authoring system with the desired characteristics.

The ideas of Alash are the spiritual value of the Kazakh people, which determine the development priorities of our state and historical policy. The formation of the USSR and the subsequent totalitarian vector of development conditioned the persecution and exilement of the Alash national intelligentsia. As the result of the repressive policy the majority of the best sons of Kazakh nation were arrested, shot, exiled to camps and forced to flee abroad. There in a foreign land, including in the territory of Xinjiang in China, they continued to spread the progressive ideas of Alash. The authors believe that the ideas of Alash played a role in the creation of the independent Republic of East Turkestan, which existed for five years (1944-1949). The authors examine in the prism of historical events the evolution of Alash ideas since the emergence of its leaders on the territory of East Turkestan, as well as the impact of Alash ideology on the scale of the national liberation struggle. The content of the article demonstrates the main publicity channels which played a particular role in the spread of the Alash idea. Firstly, it is the information obtained from Kazakh, Saryarka newspapers and letters from Aykap magazine. Secondly, these were the Alash emigrants themselves, who were active in spreading the idea of independence in the emigrant community. Third are the new generation, the followers of Alash, who grew up on Alash ideology, poets and writers. The authors show that, as a result of the ideology created by the PRC in 1949, all non-ethnic dissent was banished.

Abstract Elevations in technology of semiconductor materials allow for new vehicle systems use for improvement in the standard ones. One of the most promising materials for achieving an efficacy of more than 50% is polyaniline, which belongs to the class of conductive polymers that has semiconducting peculiarities. For instance, a new generation of semiconductor elements based on the Peltier-Seebeck effect makes it possible to use them to create thermoelectric generators, which means to use the thermal energy of the exhaust gases of internal combustion engines (ICE) to generate electrical power. The second area where Peltier-Seebeck semiconductor elements find application in automobiles are modular climate control systems. Due to the absence of moving parts and relatively small dimensions, they allow the creation of individual climatic zones in the car interior. An elegant design and technological solution is the placement of similar thermal semiconductor modules inside the driver’s and passenger’s seats, which makes it possible to transfer heat more efficiently and make climatic zones more apparent. The article considered engineering options for the design of climate control units based on Peltier elements and the creation of a prototype. The issues of integration into the vehicle on-board network and the features of power control are considered. The studies and results of this paper can contribute to improving the energy efficiency and technosphere safety of vehicles.

This essay examines the reception of the ten-year Complete Works translation project undertaken by the Finnish publishing company Werner Söderström Oy (WSOY) in 2004-13. Focusing on reviews published in the first and last years of the project, the essay details ongoing processes of Shakespeare (re-)canonization in Finland, as each new generation explains to itself what Shakespeare means to them, and why it continues to read, translate and perform Shakespeare. These processes are visible in comments from the series editors and translators extolling the importance of Shakespeare’s work and the necessity of creating new, modern translations so Finns can read Shakespeare in their mother tongue; in discussions of the literary qualities of a good Shakespeare translation, e.g. whether it is advisable to use iambic pentameter in Finnish, a trochaic language; and in the creation of publisher and translator “heroes,” who at significant cost to themselves, whether in money in terms of the publisher, or time and effort in terms of the translators, labour to provide the public with their Shakespeare in modern Finnish. While on the whole reviewers celebrated the new translations, there was some resistance to changes in familiar lines from older translations, such as Macbeth’s “tomorrow” speech, suggesting that there are nevertheless some limits on modernizing “classic” translations.
