Material Provision of the First and Second Generation of Protestant Preachers
No full textThe presented study deals with the matter of the material provision of the first and second generation of Protestant preachers following the issue of the Patent of Toleration. The first generation of preachers was, exclusively, of Hungarian origin, while the second one was represented by preachers coming from the domestic, Czech background. Solely the faithful were responsible for the livelihood of Protestant preachers. On the basis of comparison of both generations’ lists of contributions, assessment of the country’s economic situation and the strength of the then currency, we are able to find out what their financial state was. The first-generation preachers are traditionally viewed as poor pastors who, because of poverty, often changed church communities or abandoned the Czech provinces. The situation of the second-generation preachers is not known so well, however, usually a stable and secure position is attributed to them. Looking closer at both the generations, it is evident that in neither of them the financial state of preachers was definite and their material provision did not depend so much on the amount of service but on the broader economic and social aspects.The presented study deals with the matter of the material provision of the first and second generation of Protestant preachers following the issue of the Patent of Toleration.

Searching for a Younger Self: Time, Music and Ageing Masculinities in the Novel A Visit from the Goon Squad by Jennifer Egan
No full textThe idea that literature matters for an understanding of socio-cultural processes and phenomena is confirmed in Jennifer Egan’s inspiring novel A Visit from the Goon Squad. Four decades since the appearance of punk rock music and culture it has become necessary to incorporate issues concerning ageing in the analysis of musical subcultures (Bennet, 2018, Jennings, 2015). The contrasts of past and present, youth and ageing, older and young generations suggest that time is the most important category as an almost invisible, silent, relentless and invincible driving force. This emphasized temporal perspective shows the inevitability and incessancy of changes not only in human lives but also in the ageist world of the music industry

AIR INFRASTRUCTURE FUNDING SYSTEMS IN LIGHT OF STABILITY DURING CORONACRISIS: EU VS USA
No full textPríspevok konfrontuje systémy financovania leteckej infraštruktúry v Európskej únii a USA vzhľadom na koronakrízu. Pretože oba systémy sú spôsobom financovania previazané na leteckú prevádzku, koronakríza ochromila financovanie leteckej infraštruktúry v oboch celkoch, a to v okruhu prevádzkového aj investičného financovania. Nutnosť zachovania kontinuity investičného rozvoja leteckej infraštruktúry v čase coronakrízy vyvolala potrebu záchrannej reakcie, ktorá sa v EÚ zásadne líši od USA. V porovnaní so systémom v EÚ má systém financovania a strategického riadenia leteckej infraštruktúry v USA lepšiu adaptabilitu na krízu. V systéme financovania leteckej infraštruktúry v EÚ je „Achilovou pätou“ systému zložitosť pravidiel štátnej pomoci a inštitucionálna výstavba systému štátnej pomoci.The paper confronts the funding systems of air infrastructures in the EU and the US during coronacrisis. As both funding systems of the infrastructures are derived from air operation, coronacrisis paralysed the systems in terms of investment needs and operating needs as well. Therefore it was inevitable to rescue the systems to keep them functional and in this regard the EU system is significantly different from that in the US. Comparing the EU and the US, the system of air infrastructures funding in the US turns out to be better with regard to adaptability. In the EU, the complexity of state aid rules and institutional framework of state aid is seen by us as the „Achilles heel“ of European system
APPLICATION OF SELECTED CONTROLLING TOOLS IN COST MANAGEMENT OF TRANSPORT COMPANIES AND THEIR USE IN REPORTING
No full textZ hľadiska zvyšujúcej sa zložitosti podnikových systémov a ich využitia je nevyhnutným základom každej úspešnej cesty taký systém, ktorý integruje nielen spracovanie informácií, tvorbu plánov, ale aj analýzu a kontrolu. Veľmi dôležitá je aj možnosť prijímať správne a rýchle rozhodnutia, čím sa znižuje pravdepodobnosť možných rizík a nebezpečenstiev na minimum. Controlling je v tomto kontexte veľmi dôležitým nástrojom pre podporu riadenia a rozhodovania. Príspevok prináša analýzu controllingových nástrojov s ohľadom na ich uplatnenie v riadení dopravných spoločností. Dôraz je kladený najmä na controllingové riadenie nákladov, ich controllingovú kategorizáciu v špecifických podmienkach dopravných podnikov ako aj ich následné využitie pri riadení zisku. Pre dosiahnutie cieľa boli využité viaceré metodológie, nielen pri čiastkových cieľoch - získavaní a spracovávaní teoretických poznatkov - ale aj pri ďalšom riešení, návrhoch praktického využitia vybraných nástrojov controllingu v dopravných spoločnostiach. Predmetná problematika bola riešená s využitím vybraných kvalitatívnych metód, opierajúcich sa o indukciu so snahou pozorovať, zisťovať pravidelnosti, vytvárať závery a teórie za účelom získania naratívnych výstupov. Teoretické výstupy sú výsledkom spracovania dostupných poznatkov o controllingu a jeho vývoji, praktická rovina poskytuj výsledok vo forme návrhu uplatnenia vybraných nástrojov controllingu v podmienkach dopravných spoločností, pôsobiacich v Slovenskej republike. Príspevok možno považovať za relevantný zdroj poznania a pochopenia riešenej problematiky, ponúka metodický návrh, uplatniteľný vo všeobecnosti pre podniky, ktorých manažment sa pre zavádzanie a využívanie controllingových nástrojov rozhodne.In view of the increasing complexity of business systems and their use, a necessary basis for any successful journey is a system that integrates not only information processing, planning, but also analysis and control. The ability to make the right and quick decisions is also very important, reducing the likelihood of potential risks and dangers to a minimum. It is a tool to support management and decision-making, it makes it easier for managers to make decisions. The paper presents an analysis of controlling tools with regard to their application in the management of transport companies. Emphasis is placed especially on controlling cost management, their controlling categorization in the specific conditions of transport companies as well as their subsequent use in profit management. To achieve the goal, several methodologies were used, not only for the partial goals - acquisition and processing of theoretical knowledge - but also for further solutions, proposals for the practical use of selected controlling tools in transport companies. The subject matter was solved with the use of selected qualitative methods, based on induction with an effort to observe, find out the regularity, draw conclusions and theories in order to obtain narrative outputs. Theoretical outputs are the result of processing available knowledge about controlling and its development, the practical level provides the result in the form of a proposal for the application of selected controlling tools in the conditions of transport companies operating in the Slovak Republic. The paper can be considered a relevant source of knowledge and understanding of the issues addressed, offers a methodological proposal, applicable in general to companies whose management decides to implement and use controlling tools

CAPTURING OF UNEVEN DEFORMATIONS OF LIGHTENED 3D PRINTED PARTS
No full textThis paper deals with the problematics of tensile testing of maraging steel lightweight cylindrical samples with internal structures, intended for automotive application. The samples were made with DMLS technology and tensile tested under the static strain rate of 0.002 s-1. During the loading, uneven deformations and multiple necking occurred on the samples. The mentioned effect significantly affects the state of stress and deformation at the final fracture zone, as well as the total deformation into the fracture, which means that it actually distorts the standard tensile test record. Therefore, a methodology for capturing the deformation response using the ARAMIS optical system was proposed. The methodology is presented and verified by a set of experiments for BCC internal structure
Social aspects of the professionalization of midwives in Luxembourg (1800–1940)
No full textThis article proposes an open, interdisciplinary approach to understanding how women assisting at birth in Luxembourg in the late eighteenth century evolved to become specialised medical professionals in the early twentieth century. To do this, it is necessary to study the administrative organisation of training, recruitment policies and the form and content of the courses involved in the creation of a new health worker: the midwife. This individual often assumed the role of midwife, vaccinator, doctor of the poor or paediatric nurse.This article proposes an open, interdisciplinary approach to understanding how women assisting at birth in Luxembourg in the late eighteenth century evolved to become specialised medical professionals in the early twentieth century.
