Our research objective is to identify the differences between those two segments evaluating their different attributes. Besides, the paper provides the related literature review. It designs a suitable data collection and evaluation methodology for conducting the research in the Czech Republic where such studies are missing
The Rural South as a Gay Men’s Haven in Andrew Holleran’s Dancer from the Dance and Jim Grimsley’s Boulevard
No full textFreed by the gay liberation movement of the 1960s and free of the fears brought by the arrival of AIDS in the early 1980s, the 1970s is a period often celebrated as the golden period of American gay urban areas. At the same time, some writers (writing both in the 1970s and later) point out the gilded rather than golden nature of the milieux, with many characters attempting to leave the urban areas. In this context, novels as diverse as Andrew Holleran’s Dancer from the Dance (1978) and Jim Grimsley’s Boulevard (2002) offer a surprising image of the rural South as a haven for these gay men running away from urban areas. The present essay analyzes the development of this idea in the two novels
The Duels of Monarchs: the Issue of Ritual Communication from Antiquity to the Present Day
No full textThe paper seeks to explain the significance of the phenomenon, which were the duels of monarchs. They appear to be best understood if analyzed in the context of ritual communication. Challenges to monarchs to fight a duel, although none actually took place, were widespread gestures from antiquity to the modern times. They are known from many documented, literary (Iliad) and iconographic sources and also from chronicles. It appears, however, that historians have not so far devoted proper attention to them and failed to correctly interpret this problem and explain it adequately. The present study is an attempt to look at the subject from a new angle.The paper seeks to explain the significance of the phenomenon, which were the duels of monarchs.

Bet on a Risky Card. Imperial Army Service and the Social Downfall of the Count Family of Raduits de Souches at the Turn of the 17th and 18th Century.
No full textThe paper sets a goal to clarify, by the form of a case study into the destiny of the three generations of the native French family of the Raduits, the connection between the economic resources, which the mentioned family could gain and mobilize, and the economic and financial aspects of army service. They were not only the inherent part of aristocratic warrior careers, but they also, in the situation of yet undeveloped fiscal mechanisms of a premodern state that was still searching for ways how to finance its permanent army, represented a risk factor which, to a considerable extent, decided about success or failure not only of the particular individuals, but as well their families and other generations of the dynasty, in the strictly socially stratified society of the early modern period.The paper sets a goal to clarify, by the form of a case study into the destiny of the three generations of the native French family of the Raduits, the connection between the economic resources, which the mentioned family could gain and mobilize, and the economic and financial aspects of army service.

THE COMPARISON OF THE SELECTED METHODS FOR DETERMINING THE SIZE OF THE SAFETY STOCK AND THEIR APPLICATION IN THE FOOD INDUSTRY
No full textProblematiku řízení zásob řeší denně mnoho podniků. Je to dáno zejména dvěma protichůdnými snahami; podniky se jednak snaží maximálně uspokojit svoje zákazníky, avšak na druhé straně chtějí eliminovat množství kapitálu vázaného v zásobách. Pojistná zásoba může zachycovat tři základní druhy odchylek – na straně vstupu, výstupu a ve spotřebě. Správné nastavení velikosti pojistné zásoby má vliv na ekonomiku podniku a zákaznickou spokojenost. Tento článek komparuje vybrané metody pro stanovení velikosti pojistné zásoby a aplikuje je v praxi v prostředí potravinářského průmyslu.The problem of inventory management solves many businesses every day. This is mainly due to two conflicting trends. Both companies are striving to satisfy their customers, but on the other hand, they want to eliminate the amount of capital tied up in inventories. Safety stock can capture the three basic types of imbalances – on the input, output and consumption. The correct size setting of safety stock influences the economics of enterprise and customer satisfaction. This article compares the selected method for determining the size of the safety stock and applied in practice in the food industry environment
NEW METHODOLOGY FOR TRANSPORT CONNECTIONS ASSESSING DEPENDING ON THE INTEGRATED TRANSPORT
No full textPeriodická linková doprava predstavuje integrovaný taktový cestovný poriadok, kde je okrem pravidelne sa opakujúcej líniovej formy sledovaná aj sieťová previazanosť. Dôležitým faktorom je minimalizácia prestupných časov vo vybraných miestach - dopravných uzloch. Cieľom je minimalizácia celkového prepravného času cestujúceho z miesta A do miesta B.Základným stavebným kameňom dopravných služieb je poskytovať cestovné príležitosti vytvorením väzieb a spojení. Často sa po zavedení nového cestovného poriadku, v rámci diskusie, hodnotí kvalita cestovného poriadku subjektívnym spôsobom. Autori riešia niektoré najproblematickejšie prvky na zlepšenie kvality železničnej osobnej dopravy. V súčasnej dobe neexistuje žiadna metodika pre posudzovanie cestovných poriadkov z dopravného hľadiska ako celku. Hodnotia sa konkrétne vlaky a spojenia iba v staniciach, nie však kvalita spojenia z bodu A do bodu B.Cieľom tohto článku je predstaviť novú metodiku pre posudzovanie cestovného poriadku, pokiaľ ide o osobnú dopravu a týkajúce sa prestupy a prepojenia. Z pohľadu cestujúceho je nutné posúdiť dostupnosť cestovných príležitostí medzi vybranými bodmi na železničnej sieti. Ponuka cestovných spojení z A do B je v zásade ovplyvnená časom jazdy, počtom prestupov (zmena dopravného prostriedku) a počtom cestovných možností. Na možnosti prestupov a prepojenia má vplyv niekoľko faktorov. To je výsledok nastavenia návrhu kritérií pre vyhodnotenie spojení.Predostretá štúdia je navrhnutá v gescii zostavenia nástrojov na objektívne hodnotenie kvality spojenia verejnej osobnej dopravy. Konkrétne sa jedná o aspekty dostupnosti a času dopravných služieb vo vybraných zemepisných oblastiach v reciprocite s normou EN 13816.The periodic line transport is an integrated tact timetable, which is also a periodical liner form of surveillance and network interconnection. An important factor is to minimize the interchange times in selected areas - transport hubs. The aim is to minimize the total transit time of a passenger from point A to point B.The cornerstone of transport services is to provide travel opportunities by creating of the links and connections. Often, after the introduction of the new timetable under discussion whether it is better or worse, each approach is evaluated in a subjective manner. The authors solved some partially problematic of rail passenger quality services. At present, there is no methodology for train timetables assessing from the transportation point of view as a whole. We evaluate only specific trains and connections in the stations, but not the quality of the connection from point A to point B.The aim of this paper is to introduce a new methodology for the assessment of timetables in terms of passenger traffic focused on connectivity and linking. From the passenger’s point of view, it is necessary to assess the availability of travelling opportunities between selected points on the rail network. The travel offered from A to B is in principle affected by travel time, number of transfers (changing of the transport means, and number of travel opportunities. Several factors also affect the connectivity and linking. This is an outcome for setting of draft criteria for connection evaluation.Introduced study is designed in purview of the set up a tool for an objective evaluation of the quality of public transport service, specifically, the aspects of availability and time services in selected geographical areas in reciprocity to the Standard EN 13816
