The current study aimed to prove the existence of a significant relation between land surface temperature (LST) and local climate zones (LCZs) and its possibility to be generalized to all cities around the world with different climatic zones and characteristics. The further step in this regard was to find the effective climatic and geographical variables affecting this potential relation. For that, 25 cities all around the world with various climatic conditions were selected based on the availability of appropriate satellite images and level zero data on the World Urban Database and Portal Tool (WUDAPT). After acquiring both LST and LCZ maps the comparison between them was made with the Wilcoxon rank sum test indicating the existence of any meaningful pattern. Then, 8 climatic and geographical variables and all possible combinations thereof were assessed to determine the effective drivers on the LST-LCZ relationship. The results showed that the combination of the latitude, mean and maximum annual temperature affected this connection more than any other considered variables.

This paper analyses the protection of consumers of tourism services in EU law and consumer awareness in this domain in Serbia as a country currently negotiating accession to the EU. Consumer rights in EU tourism are defined by directives and regulations. This paper shall separately analyse two directives and one regulation that directly pertain to the protection of consumers of tourism services. Most legal sources are the codification of business practices of tourist organizations within the EU, but a part of mandatory provisions is the result of the need to protect consumers of tourism services in the domains of tourism in which they are most exposed to violation of their rights. For the needs of this paper, the survey was carried out on the territory of the Republic of Serbia, for the purpose of obtaining information on citizens' awareness of the rights of consumers of tourism services in EU countries. The main aim of this study is to determine how well informed the citizens of Serbia are regarding consumer rights in tourism and legislation that governs those rights.

In this study we focus on the evolution of the identity of those urban neighbourhoods which have formerly been separate towns. This problem is discussed using the example of the polycentric conurbation of Katowice in southern Poland, which came into being because of its mining and industrial functions. The administrative integration of this multi-level polycentric urban system is the primary background for the development of those neighbourhoods that used to be separate towns. Assuming that changes in legal and administrative status may have certain consequences regarding the social connections and identity of such neighbourhoods, this study aimed to identify such places within the analysed region. The authors also attempted to construct paths of local identity for such spatial entities, confronting them with the thesis that economic factors make them relatively homogeneous. The implementation of new development factors and the paradoxical diversity of the identities of the former towns in this mining-industrial region are also significant elements of the region's social transformation in terms of economic and spatial development.

The purpose of the paper is to provide an empirical study of employees’ ethical behavior in travel and tourism industry. A survey research was done in 2012 in the Republic of Serbia among employees in travel agencies as one of the most important subjects in heterogeneous structure of travel and tourism industry, using a questionnaire designed according to the basic theoretical principles of professional ethics. Dealing with the issue of ethical responsibility of employees in travel agencies, this work examines whether employees have business ethics awareness and what kind of individual and corporate social responsibility as part of business environment is undertaken in this regard. The findings of the study showed that employees of travel agencies are ready to act in an ethical manner, although it is the opposite of management attitudes in specific situations. Finally, the paper provides a critical evaluation of entrepreneurial activities and obstacles that travel agencies encounter while operating in the Serbian economy in transition.

For understanding hydroclimatological process chain it is crucial to identify relations between largescale climatic circulations and river discharge. The Danube is one of the most important European waterways, flowing 2.857 kilometers across the Europe and with 817.000 km2 basin. Danube River average and maximum discharges are correlated with eight atmospheric circulation patterns indices: AOi, EAi, EA/WRi, ENSOi, MOi, NAOi, SCANDi and WeMOi in 65 years period at the Bezdan gauging station in Serbia. Obtained results showed that precipitation, MOi and WeMOi have constant and dominant influences on Danube River average discharge at Bezdan gauging station, while maximum discharge is mainly influenced by precipitation and MOi. All registered correlations are positive.

This paper focuses on the highway corridor Belgrade-Novi Sad, Serbia and the relationship between the highway and surrounding nature, as an integral part of the spatial entity which the highway belongs to. The paper emphasizes a high importance of studying the physical-geographical factors in the process of highway construction in order to achieve high level of traffic safety. Particular attention was directed to climate elements – the factors that are not so visible, but still may pose a great risk to road safety. Data were taken from CARPATCLIM database and their evaluation was confirmed by the data obtained from CHEK-LISTS. It was found that the climate elements have a strong influence, but it can be successfully controlled by vegetation. Landscape design of both sides of the highway may offer a possibility of mitigating the influence of climate elements, which was also pointed out in the paper.

Over the 50-year history of Yugoslavia, there were rises and falls, successes and failures, bright and dark moments. It is thus not surprising that the many memories that people have of life in Yugoslavia are often diametrically opposed. These divergent memories of Yugoslavia are the central topic of our research. The study focuses on memories and their transmission from older to younger generations and is based on the results of a survey that was carried out in the Republic of Slovenia. The research has clearly shown that positively tinged memories of Yugoslavia predominate in the families of younger as well as older generations on the one hand while on the other hand it has become obvious that Yugonostalgia is nostalgia for something from the past and it is not a desire to experience or revive that in the present.

Hot summers with several intensive heat waves lead to strong heat-related mortality in Central and Southeast European cities. Therefore, the aim of the study was to evaluate association between maximum temaprature and mortality during the summer period in 2015 and to contribute to the future long-term assessment of heat-related mortality in urban population. The daily number of deaths of all causes and cause-specific mortality for the population of Novi Sad were used, as well as hourly air temperature data from the Novi Sad urban network (NSUNET) system. Four heat waves were detect-ed using the Huth and Kysely methods. Three heat wave periods lasted longer than ten days. In July and August, 45% of days had a maximum temperature above 30 ºC, and more than 70% of days had a maximum temperature above 25 ºC. The average number of deaths was higher during the heat wave days. Significant association was found between Tmax and all-cause, cardiorespiratory, non-cardiorespiratory in total population, all-cause and cardiorespiratory mortality in the age group 65 and over. This study demonstrates a high magnitude of relation between mortality and temperature. Finally, the results show that population in urban areas is highly vulnerable during heat waves.

The aim of this paper was to assess the impact of heat-waves on mortality in ten Czech cities, using data recorded during the summers of 2015 and 2016. Temperature-related mortality during heat-waves was investigated by comparing mortality figures on heat-wave days and those on other days by means of the Mann-Whitney U test. Results for all-cause mortality, cardiovascular and respiratory diseases (CVD+R) mortality, as well as for mortality in the over-65 age group, show statistically significant differences (p <0.05) during heat-waves compared with other days in seven of ten cities investigated. The effect of heat-waves on mortality did not reach statistical significance in Olomouc, Plzeň and Liberec. The results suggest that further studies addressing spatial patterns of mortality during heat-waves in urban areas are required to assess the vulnerability of the urban populations in particular cities and types of neighbourhood.
