Izazovi transnacionalizma među drugom generacijom srpskih migranata u Švajcarskoj
Get PDFThis paper presents the results of a survey conducted among members of the second generation of Serbian migrants born in Switzerland. Thanks to the data obtained through the application of qualitative research, there are presented activities of the respondents in the transnational area. Their engagement on the route between Serbia and Switzerland is reflected in four areas of transnationalism: direct/indirect contacts, transnational engagement in the receiving state, remittances and visits to the country of origin and return plans. The results indicate that children of migrants who come from a family whose members are active in a transnational space, in most cases, adopt the same norms of behavior and it plays a crucial role in the process of identity formation. However, their transnational behavior on the relationship between the two states has different form, and the transnational activities examined do not condition each other.U radu su prikazani rezultati istraživanja sprovedenog među pripadnicima druge generacije srpskih migranata rođenih u Švajcarskoj. Zahvaljujući podacima dobijenim primenom kvalitativnog istraživanja, predstavljene su aktivnosti ispitanika u transnacionalnom prostoru. Njihovo angažovanje na relaciji između Srbije i Švajcarske je prikazano kroz četiri oblasti transnacionalizma: direktni/indirektni kontakti, transnacionalno angažovanje u državi prijema, doznake, posete državi porekla i planovi o povratku. Rezultati ukazuju da deca migranata koja potiču iz porodice čiji su članovi aktivni u transnacionalnom prostoru, u većini slučajeva, i sama usvajaju iste norme ponašanja, što ima presudnu ulogu u procesu formiranja identiteta. Međutim, njihovo transnacionalno ponašanje na relaciji između dve države je različitog oblika, te ispitane transnacionalne aktivnosti ne uslovljavaju jedna drugu
Specifičnosti klime Danilovgrada (Crna Gora)
Get PDFDanilovgrad and the Bjelopavlića Plain belong to the submediterranean zone of the Mediterranean climate region. The aim of this paper was to determine some specific characteristics of the Danilovgrad climate, such as the degree of continentality, aridity and bioclimatic characteristics. Data used in the research cover the period 1955-2011. The results of the study showed the dominance of the continental effect on temperature, while oceanicity was less pronounced. In hygric terms, during most of the year the climate of Danilovgrad is characterized as low humid to perhumid. Moreover, in the period October-March it is very humid, which points to the domination of oceanic influences. During the three summer months, it is dry to very dry. Based on the average monthly values of the equivalent temperature - an indicator of physiological (subjective) feeling of heat, the winter months in Danilovgrad are not assessed as very cold. It is cold in January, and in February and December it is cool. It is fresh in March and November, comfortable in April and October, and warm in May and September. In Danilovgrad, in summer it is overheated and a little muggy. All considered indicators point to quite pronounced oscillations during the year, especially in terms of humidity. Comparing the obtained results with Podgorica, it can be concluded that the climate of Danilovgrad is more continental, a bit colder and wetter.Danilovgrad je centralno i najveće naselje na području Bjelopavlićke ravnice u Crnoj Gori. Sa klimatskog aspekta, područje Bjelopavlićke ravnice je pogodno za život i razvoj poljoprivrede. Međutim, u do sada poznatim klasifikacijama klime za Crnu Goru, dat je uopšteni opis pojedinih regija i mesta, uglavnom na osnovu analize srednjih mesečnih temperatura vazduha i količine padavina. Za Danilovgrad se može reći da ima blago modifikovnu mediteransku klimu, a to znači da su leta topla i prilično sušna, a zime blage i kišovite. Prema Kepenovoj klasifikaciji, klimatska formula Danilovgrada je Csa, prosečna godišnja temperatura je 14,60C, a godišnja suma padavina 2.216 mm. Cilj nam je bio da klimu ovog mesta što bolje i podrobnije opišemo, kroz analizu termičke kontinentalnosti, aridnosti i bioklimatske karakteristike. Analizom kombinovanih klimatskih elemenata, dat je kompleksniji prikaz i kvalitetnija karakterizacija klime Danilovgrada. Smatramo da će istraživanje imati značaja za lokalnu zajednicu u smislu boljeg razumevanja prirodnog okruženja i da se dobijeni rezultati mogu primeniti u poljoprivredi, vodoprivredi i energetici, turizmu i drugim delatnostima od važnosti za budući razvoj Danilovgrada i Crne Gore. Takođe, rezultati dobijeni u ovom radu biće korisni nauci, struci i opštem obrazovanju stanovništva, jer se radi o tematici koja sve više participira kod današnjeg čoveka. Za razmatranje specifičnosti klime Danilovgrada, korišćeni su podaci za instrumentalni period 1955-2011. Rezultati istraživanja su pokazali dominaciju kontinentalnog uticaja na temperaturu, dok je maritimnost slabije izražena. U higričkom smislu, tokom većeg dela godine klima Danilovgrada se karakteriše kao slabo humidna do perhumidna. Štaviše, u periodu oktobar - mart je veoma vlažno, što govori o dominaciji maritimnih upliva. Sušno do veoma sušno je tokom tri letnja meseca. Prema bioklimatskim pokazateljima, ni jedan mesec se ne karakteriše kao veoma hladan. Na osnovu srednjih mesečnih vrednosti ekvivalentne temperature, koja je korišćena kao pokazatelj fiziološkog (subjektivnog) osećaja toplote, tokom januara je hladno, a u februaru i decembru veoma prohladno. Sveže je u martu i novembru, ugodno u aprilu i oktobru, a toplo u maju i septembru. U Danilovgradu je leti pregrejano i malo zaparno. Svi razmatrani pokazatelji ukazuju na prilično izražene oscilacije tokom godine, naročito u pogledu vlažnosti. Dobijeni rezultati ukazuju da Danilovgrad ima slične termičke, higričke i bioklimatske karakteristike kao Podgorica (Burić et al., 2007), jer je rastojanje između ova dva grada oko 20 km. Ipak, Danilovgrad je više kontinentalniji, malo hladniji i vlažniji od Podgorice
Forest fires in Finland - the influence of atmospheric oscillations
Get PDFIn Finland, in the period 1996-2017, 28,434 forest fires were recorded (an average of 1,292.5 per year), and the total burned area was 11,922 ha (an average of 541.9 ha per year). In both cases, a statistically nonsignificant downward trend was recorded. Forest fires in Finland do not represent a particularly significant problem, primarily due to climatic characteristics, well-organized fire protection, and low density of population. The research of climate influence included the Atlantic Multidecadal Oscillation (AMO), the North Atlantic Oscillation (NAO), and the Arctic Oscillation (AO). The statistically significant values (p lt = .05) of Pearson correlation coefficient were recorded for the August values of NAO and the surface area of burned forest (-0.44), the June values of NAO and the average surface area of forest burned per fire (-0.51) and the May AO values and the average surface area of forest burned per fire (-0.45). For the June values of NAO and the average surface area of forest burned per fire, the Lomb periodogram shows four significant peaks, and the match is at two, at 2.4 and 3.4 years, which supports the hypothesis of the connection between NAO and forest fires in Finland
An analysis of the influence of air temperature and humidity on outdoor thermal comfort in Belgrade (Serbia) using a simple heat index
Get PDFThe main objective of this paper is to study the outdoor thermal comfort of the central urban zone of Belgrade during summer season in order to examine how different bioclimatic conditions affect human body. For this purposes Humidex, a simple heat index was applied. The research involved analyzing different Humidex values, the so-called "sub-indices" calculated based on hourly (7:00 and 14:00), mean daily and maximum values of meteorological parameters (air temperature and humidity) that were recorded at the meteorological station Belgrade - Vracar.), for the period 1999-2018. Outdoor thermal comfort in Belgrade is generally more adverse in July and August, resulting in most days belonging to the categories of "some discomfort" (30-39) and "great discomfort" (40-44), with periodic recording of the most severe categories of heat stress, as a category "very dangerous"(Humidex>55). Category of "very dangerous" heat stress shows linear increase during July, with positive trend of 0.03 days/10 years. The findings also show that from 1999 to 2018, mean index value gradually rose and values of sub-indices Humidex(14h) and Humidex(Tmax) have exceeded thresholds 40 for great discomfort and 45 for dangerous heat stress more often then in the previous decades
Assessment of natural environment for the purposes of recreational tourism-example on drina river flow (Serbia)
No full textThe role of applied geography has been increasing in interdisciplinary research due to the advantage of knowing spatial processes and relations. This role has reflected in the geo-ecological evaluations of a particular geographical area used for different social purposes. This paper represents the GIS analysis of the natural environment of a part of the Drina River flow in wider terms so to apply in recreational tourism. The quantitative V-Wert diversification method has used for the study with the focus on identification of the area that might be favorable for recreation. The analysis is based on the knowledge of natural geographical elements. Criteria taken into consideration are the edges of the forest and water, the relief energy, the manner in which the landscape is used and the climate factor. According to the benefits of the said purpose, the unfavorable areas amount to 1,520 km2 (34.43%), conditionally favorable areas amount to 2,418 km2 (54.77%), favorable areas amount to 310.33 km2 (7.03%), very favorable areas amount to 163 km2 (3.69%) and the most favorable areas amount to 3.67 km2 (0.08%). The category of very favorable recreation contains a large area (167 km2) from the total amount of 4245 km2
Neocomian Fahliyan formation carbonates in the oil well X2 (Dorood oil field, Persian Gulf): Biostratigraphic data from benthic foraminifera and algae
No full textThe Fahliyan Formation of the Khami Group is the most important oil and gas reservoir in southwestern Iran. The formation attains a thickness of 435.5 m in the oil well X2 in Dorood oil field, Persian Gulf It is represented mainly by thin-bedded limestones. This formation unconformably overlies the evaporate late Jurassic Hith Formation and conformably underlies the Gadvan Formation. Integrated palaeontological and sedimentological studies supported by an analysis of 150 thin-sections led to the identification of 21 benthic foraminiferal genera dominated by agglutinated forms with an additional 8 algal genera. Two foraminiferal biozones of Berriasian through Hauterivian age include the Pseudochrysalidina (Dokhania) arabica acme zone and Pseudocyclammina lituus-Coscinoconus assemblage zone, and an algal zone includes the Salpingoporella annulata range zone have been recognized. The correlation of the lower Cretaceous petroleum source rock in the Persian Gulf with regions from Tethyan Realm is limited by the lack of the analog formation that can be used for comparison. In this way, the foraminiferal zones are correlated with coeval zones in south and southwest of Iran
Renewable energy potentials for the post-socialist urban environments of Ub (Serbia) – a shallow geothermal approach
No full textThe energy demand for heating of urban environments during socialist and post-socialist times was usually covered by fossil resources such as coal, oil or gas. Therefore, urban infrastructure was configured with district heating networks usually powered by a nearby coal-fired power station. If there was no available network, apartments and houses were mostly heated by coal or oil fired stoves. As the urban energy infrastructure stayed mostly untouched in post-socialist times, these energy resources with huge environmental impact and enormous greenhouse effects are still state of the art in many post-socialist cities and towns. The town of Ub, Kolubara District, is located in an industrial area of central Serbia in the immediate vicinity of the huge opencast coal mines named “Kolubara”. The town of Ub had 5,089 (2011) inhabitants and the whole municipality of Ub had 23,775 (2011). Due to its more rural structure, the existing building development is not so dense when compared to major Serbian cities such as Belgrade, Novi Sad or Niš. The structure of Ub allows the application of cheaper horizontal collector systems next to common borehole heat exchangers. This paper will show the renewable energy potential in the urban environment of Ub and the possibility of low environmental impact solutions in such urban environments using an existing pan-European data-set (ThermoMap), investigation tools for geothermal potentials, GIS mapping, and regulations for geothermal installation in Kolubara District.Editors: Ivan Ratkaj, Danica Šantić, Marija Antić, Aljoša Budovi
The contribution of domestic tourism to the balanced regional development of Serbian province of Vojvodina
Get PDFDomestic tourism has positive effects on balanced regional development, as well as numerous non-economic effects. Domestic overnight stays amount to 59% of total overnight stays in the Serbian province of Vojvodina, which is known for diverse tourist attractions in both rural areas and urban centres, providing basis for multi ple forms of nature-based and cultural tourism. However, its share in the country’s domestic overnight stays amounts to only 13%. The aim of this research is to explore the domestic tourist turnover on a municipal level by taking into consideration the relative number of overnight stays (2017), its growth trend in the past five years (2012–2017) and the domestic-international overnight stay ratio (2017). Based on their individual share in the province’s overnight stays and their positive or negative growth trend, municipalities were classified into four categories. The analysis focused on 38 municipalities of Vojvodina, while the remaining eight were omit ted due to insufficient tourist turnover, whereby data from the official tourism statistics was used. Dominance of domestic tourism and positive growth were established in 82% and 76% of municipalities, respectively. Managerial implications of the findings are discussed
Shrinking cities in Serbia - regional differentiation and trajectories of post-socialist urban transformation
Get PDFUrban shrinkage has been common phenomena for many European cities over the last decades. This process, accompanied by rapid demographic and socioeconomic changes, affected large areas in post-socialist countries forming a new “pole of shrinkage". Although shrinkage processes produced rather homogeneous urban transformation In CEE from the macro perspective, it seems to be both spatially and temporally uneven from micro perspective, causing different development tra- jectories among post-socialist cities and uneven regional development. The transi- tion from a centrally governed and urban-based industrialization to a neoliberal market economy and new multiparty democratic system, together with the collapse of socialist Yugoslavia, civil wars, and political and economic crumple during the 1990s, has brought significant changes to the structures of Serbian cities. Urban areas in Central Serbia and Vojvodina, with 167 urban settlements according to of- ficial (administrative) criteria, and 59.4% of total population, are facing population loss, which is closely related to the out-migration and population aging. This paper focuses on different development dynamics that have produced heterogeneous de- velopment patterns of urban space in Serbia. Diverse categories of the clties have been represented, from the most developed urban centres to the small towns, which are in the stage of depopulation and economic decline. The main goal of this research is to undt'rstand the pace and scale of shrinkage process, together with its causes and consequences, and to determine different types of shrinking cities in Serbia. This should act as a starting point for future development strategies that will have to recognize the heterogeneity caused by different level of shrinkage and diverse development opportunities for the urban settlements in Serbia.Editors: Ivan Ratkaj, Danica Šantić, Marija Antić, Aljoša Budovi
