GEOCITY—A NEW DYNAMIC-SPATIAL MODEL OF URBAN ECOSYSTEM
Full text linkIn this paper the initialization of the city is considered, which consists of several steps, including the creation of city objects with their locations, creation of residents with their attributes and own daily schedules, etc. A description of the model is provided as a tuple of attributes. The adequacy of the simulation model is checked based on the statistical data from the city of Lviv, Ukraine. Generated locations of city ecosystem objects are presented. The daily schedule of residents is simulated. A possible work schedule for each specialty is given, and separate schedules are created for working days and holidays. A unique schedule is predicted for the resident, which depends on their age and work specialty. The dynamics of visits to facilities by residents on weekdays and at weekends are analyzed. Based on the conducted experiments, the adequacy of the model and its realistic reflection of the functioning of the city's ecosystem during the day are proven. It means that by using this model, researchers can assess the impact of different behavioral scenarios on the residents within the city ecosystem more reliably. This enables a better understanding of how certain actions or changes in behavior can affect the spread and control of diseases in a specific geographic area. This model has the potential to serve as a foundation for future modeling of systems at the medium and macro scales
ENVIRONMENTAL ASSESSMENT OF AL-HILLAH RIVER POLLUTION AT BABIL GOVERNORATE (IRAQ)
Full text linkIn this study, the environmental characteristics of Al-Hillah River were studied using geoinformatics applications, which is one of the geospatial techniques (GST). Applying this methodology, a geographic information system was developed, and it was supplied with laboratory data for the physical and chemical properties of 16 parameters for 2021. These data were linked to their spatial locations, using radar imagery of the Digital Elevation Model (Shuttle Radar Topography Mission), and Landsat ETM+7 satellite image. The results indicated that Al-Hillah River was affected by the liquid discharges of factories, cities, and farms spread on its sides, especially in the cities of Sadat Al-Hindiya, Al-Hillah, and Al-Hashimiyah. The seasonal changes in the climate affected some characteristics, including water temperature, pH, turbidity, total dissolved solids, and total hardness. The study showed that the concentration of sulfate (SO4) has risen above the permissible limits for the waters of Iraqi rivers. There are relatively high hardness and alkalinity values, but they were within the permissible limits. The study also showed that most of the results of environmental parameters that were used in the laboratory, were within the permissible limits of Iraqi water, except for sulfates. The justification for conducting this study is to help government agencies and decision-makers to adopt a correct vision for development projects that serve Babil Governorate. Also, it is the first time that the environmental characteristics of Al-Hillah River are studied using geoinformatics applications
STAKEHOLDERS’ EXPERIENCES WITH PARTICIPATIVE APPROACH IN TOURISM
Full text linkTourism stakeholders’ participation is mostly needed for planning purposes because they have better insights regarding various issues present on a local level. A participative approach enables tourism stakeholders to influence and control, to a certain degree, the development of tourism in their community. However, there is a lack of research on stakeholders’ understanding of a participative approach that has been identified. This study uses a qualitative research approach where a focus group (FG) with key stakeholders was employed to examine the mechanism behind the participative approach. Namely, this paper presents the findings about the local stakeholders’ experiences with a participative approach and their opinions regarding how to foster this type of initiatives in tourism settings. Data presented in this paper were collected during a discussion with an FG and processed using thematic analysis. The thoughts and opinions of stakeholders were analyzed by taking into consideration barriers and enablers related to the implementation of a participative approach. The main focus was placed on bottom-up initiatives, but other types were included as well. Identified barriers and enablers were categorized into four themes: approach necessity, appropriate stakeholders selection, correct application of the approach, and stakeholders’ motivation
MORPHOLOGICAL APPROACH FOR THE TYPOLOGICAL CLASSIFICATION OF WATERFRONT REVITALIZATION
Full text linkResearchers from multiple disciplines have proposed classification systems for waterfront transformations: generational (according to the date of their construction) and functional (based on the function assigned to the land post-harbor use). However, an analysis based on the spatial features of the former port areas and their meaning for the waterfront transformation has been missing. This contribution is an attempt to fill this gap by proposing a classification based on morphological approach. It uses selected case studies based on cluster sampling method, following a fractal reading approach of the waterfronts, to capture a representative sample and to generalize the study following a deductive logic. Using satellite images and maps, this article first identifies the areas where the waterfront was revitalized and then it analyzes the type and function of these spaces according to the classical classifications existing in the literature on the subject. A morphological approach used as methodology framework was based on the analysis of satellite images and the cartography of the waterfront areas with simplification algorithm on ArcGIS. The resulting morphological classification of waterfront transformations reveals the relationship between the built form of the former port areas, classified here as convex, concave, or linear spaces, and the kind of revitalization type respectively classified as ribbon-shaped, convergence, or dilatation. The conclusions about the relationships between the built form available for waterfront transformations and the most appropriate type of revitalization can provide concrete indications for a sustainable future transformation of port cities, especially cities whose reconversion is lagging behind
THE ROLE OF PROFESSIONAL MODULES IN SECONDARY VOCATIONAL SCHOOLS FOR THE SELECTION OF THE FIELD OF COLLEGES
Full text linkThis paper examines the connection between secondary vocational education and continuing education. The influence of professional subjects and their impact on students and the creation of attitudes about further education, as well as the implementation of various, combined training models, are studied in particular. For the purposes of this research, a total of 201 students from three secondary vocational schools in the fields of trade, catering, tourism, economics, law, and administration were surveyed using a random sampling method. The educational profiles of the tested students are economic technician, tourist technician, cook, and waiter. The research objective was to determine whether the quality of professional subjects is important when choosing further tourism studies. In addition to the fact that teaching professional subjects develops certain students’ competencies, the application of the quantitative methodology in the research showed that it also affects the choice of future educational profiles with high school students. The surveyed students have significantly opted for the choice of faculties and colleges of applied studies in natural and social sciences and humanities
PEDO-CLIMATIC CHANGES OF DRAINED FLOODPLAIN SOILS WITHIN THE FOREST-STEPPE ZONE OF THE REPUBLIC OF BASHKORTOSTAN (RUSSIA)
Full text linkThe article provides an assessment of climatic characteristics and changes in floodplain soils after the implementation of a drainage system. The study was conducted in the northern forest-steppe zone of the East European Plain (Republic of Bashkortostan, Russia). Through the analysis of long-term meteorological observations from 1961 to 2020, it was found that there was a steady increase in air temperature in all months and throughout the year, an increase in the period with positive temperatures, a slight increase in annual precipitation, and a reduction in precipitation during certain months of the warm season. Over the past 40 years, the drainage system has transformed the soil cover from Gleysols to Anthrosols, due to a decrease in the level of groundwater, agricultural use, as well as warming of the climate in the region. Thus, the transformation of soil cover can potentially contribute to climate change through the depletion of soil organic carbon stocks and increased greenhouse gas emissions. Nevertheless, currently, the natural and climatic conditions, morphological, water-physical, and agrochemical properties of Anthrosols allow for the production of two harvests of fodder crop (Bromus inermis L.) during the vegetation period. In general, the change in climatic indicators in the study area is consistent with the global trend. Our results underscore the sensitivity of soil systems to climatic variations and human activities, highlighting the need for local studies to understand regional and global environmental changes
FREQUENCY ANALYSIS OF ABSOLUTE MAXIMUM AIR TEMPERATURES IN SERBIA
Full text linkThis paper describes the frequency analysis of absolute maximum air temperatures, using annual maximum series (AMS) in the period 1961–2010 from 40 climatological stations in Serbia with maximum likelihood estimation of distribution parameters. For the goodness of fit testing of General Extreme Value (GEV), Normal, Log-Normal, Pearson 3 (three parameters), and Log-Pearson 3 distribution, three different tests were used (Kolmogorov-Smirnov, Anderson-Darling, chi-square). Based on the results of these tests (best average rank of certain distribution), the appropriate distribution is selected. GEV distribution proved to be the most appropriate one in most cases. The probability of exceedance of absolute maximum air temperatures on 1%, 0.5%, 0.2%, and 0.1% levels are calculated. A spatial analysis of the observed and modeled values of absolute maximum air temperatures in Serbia is given. The absolute maximum air temperature of 44.9 °C was recorded at Smederevska Palanka station, and the lowest value of maximum air temperature 35.8 °C was recorded at Zlatibor station, one of the stations with the highest altitude. The modeled absolute maximum air temperatures are the highest at Zaječar station with 44.5 °C, 45.6 °C, 47.0 °C, and 48.0 °C and the lowest values are calculated for Sjenica station with 35.5 °C, 35.8 °C, 36.1 °C, and 36.2 °C for the return periods of 100, 200, 500, and 1000 years, respectively. Our findings indicate the possible occurrence of much higher absolute maximum air temperatures in the future than the ones recorded on almost all of the analyzed stations
DETERMINATION OF WINTER TOURISM POTENTIAL AREAS IN TÜRKİYE USING A GIS-BASED MULTI-CRITERIA ANALYSIS
Full text linkTourism, one of the expeditiously growing and most important sectors, contributes to the national economy by increasing employment and foreign exchange income. As in many countries, the place of tourism in the country's economy is very important in Türkiye (formerly known as Turkey). As one of the sources that have contributed significantly to the country's economy for many years, it has played a locomotive role in its development. Türkiye is trying to increase its share of international tourism revenues with investments and incentives. Although it is a country that draws attention with its areas suitable for winter tourism, the development of winter tourism centers is very slow when some aspects are taken into account. Konya Province is one of the few religious and cultural tourism centers of Türkiye. The region has qualified winter tourism areas. Bringing these areas to tourism can be an important resource for both the provincial and national economy. This study proposes a Geographical Information System based Multi Criteria Evaluation (MCE) model using Best Worst Method (BWM) to identify the most suitable locations for winter tourism facilities in the Konya region of Türkiye. Among some suitable areas determined according to the results of the analysis, Aladağ Mountain in Derbent region has been seen as the most suitable place for winter tourism investments, as it has all the features such as snow quality, transportation, and snowy day duration that should exist in a winter tourism center
FAMILY AS A SOCIAL FACTOR DETERMINING DEMOGRAPHIC TRENDS
Full text linkSociety’s demographic development holds great importance for all social processes: economy, education, science, culture, and others. Therefore, it is important to evaluate the various factors influencing the formation of demographic trends and understand their significance. This paper considers a range of sources influencing the formation of young people's attitudes toward family values, namely: the immediate environment, mass media, media content, literature, social surveys, social advertising, and propaganda, as well as bloggers as a modern element of media communications that has a fairly large influence on the young audience. The paper analyzes Russia’s policy of the demographic problem, which is associated with the currently being implemented Concept of the State Family policy in the Russian Federation until 2025 (The Concept) aimed at strengthening and protecting the family as the fundamental basis of the Russian society. The paper presents the results of mass surveys among the Rostov region youth: 1) on the key points of the Concept the sample included 450 young people aged 20–29 and 2) on the youth’s preferences for various types of mass media with a sample of 634 respondents aged between 16 and 25. It was revealed that the core foundations of the family culture are sufficiently established in the Russian Federation with the dominance of the marriage relations as free, voluntary, and equal association of men and women, which is consistent with the state policy of support and development of family values.
TOURISM IN THE CONTEXT OF CONTEMPORARY THEORIES OF REGIONAL DEVELOPMENT
Full text linkTourism is a significant segment of development policy at the national level, and it is important in terms of contributing to the Gross domestic product (GDP) diversifying of economy, reducing disparities between regions, fostering development capital, and promoting regional development. Tourism greatly contributes to the sustainable development of a region and a unit of local self-government, in an environment where sometimes there are no other alternatives for achieving that goal. Theories of regional development and tourism have evolved over a similar period after the Second World War. The concept of regional development has undergone a significant transformation through various theories. The paper analyzes the main principles of the theory of endogenous regional development and the possibility of its application for tourism research as a development factor. Tourism development policy is often created by the views of these theories. The purpose of this paper is to indicate, based on the analysis of modern ideas and approaches to regional development, whether they are suitable for the study of tourism and which factors are decisive in achieving its development function. The paper points out certain elements of theories that can individually or together represent the theoretical basis for tourism development planning in regions and local government units
