A data-driven analysis, and its limitations, of the spatial flood archive of Flanders, Belgium to assess the impact of soil sealing on flood volume and extent
No full textSoil sealing increases surface runoff in a watershed and decreases infiltration into the soil. Consequently, urbanization poses a significant challenge for watershed management to mitigate faster runoff accumulation downstream and associated floods. Hydrological models are often employed to assess the impact of land-use dynamics on flood events. Alternatively, data-driven approaches combining time series of land use geodatasets and georeferenced flooded zones also allow to assess the relationship between soil sealing and flood severity. This study presents such data-driven analysis using a spatially explicit archive of flooded areas dating back to 1988 in the Flanders region of Belgium, which is characterized by urban sprawl. This archived data, along with time series of rainfall and land use, were analyzed for three middle-sized river subbasins using two machine learning methods: boosted regression trees and support vector regression. The machine learning methods were found suitable for this type of analysis, since their flexibility allows for spatially explicit models with larger sample sizes. However, the relationship between soil sealing and flood volume and extent could not be conclusively confirmed by our models. This may be due to data limitations, such as the limited number of recorded historical floods, inaccuracies in recorded historical flood polygons and inconsistencies in the land use classifications. It is therefore stressed that continued consistent monitoring of floods and land use changes is required.sponsorship: This research was made possible by the research foundation FWO (Fonds Wetenschappelijk Onderzoek, https SAPPsei Two be/) through a PhD scholarship (Grant SB/1S01217N) to Karen Gabriels.

Bakalaura darba tapšanas procesā autors konstatējis, ka Latvijā pēdējos gados notiek brīvības atņemšanas soda progresīvās izpildes sistēmas pilnveidošana, tādējādi pietuvinot soda progresīvās izpildes sistēmas principus un piemērošanu tādām pasaules progresīvām valstīm kā, piemēram, Somija un Norvēģija.Every year, the execution of a prison sentence takes place in accordance with the progressive execution system, which provides for a gradual softening or strengthening of the sentence serving regime. The application of the progressive execution system of a prison sentence varies in different countries. The aim of the bachelor's thesis is to study the progressive execution system of a prison sentence in Latvia and its comparison with foreign regulations, as a result of which conclusions and proposals for its improvement are provided. To achieve the goal, the author has set the following tasks - to study the historical development of a prison sentence, the concept of a sentence, the legal framework, the institutional system in Latvia and its functions, to analyze the progressive execution of a prison sentence in closed and open prisons in Latvia, to compare the progressive execution of a prison sentence in Latvia, Finland, Poland and Norway. The author compared the progressive execution system of a prison sentence in Finland, Poland and Norway. In the process of writing his bachelor's thesis, the author has determined that in recent years Latvia has been improving the progressive execution system of prison sentences, thus bringing the principles and application of the progressive execution system closer to such progressive countries of the world as, for example, Finland and Norway

Authoritarianism, Erdogan and Anti-Secularisation in Turkey
No full textBakalaura darba “Autoritārisms, Erdogans un antisekulārisms Turcijā” mērķis ir izpētīt, kā Turcijas prezidents Redžeps Tajips Erdogans, izmantojot sabiedrības vēsturisko un šī brīža polarizāciju un varas konsolidēšanas metodes, veic konservatīvas politiskās reformas, kas sekmē antisekulārisma politiku Turcijā, graujot sekulāro institūciju integritāti. Darbā tiek analizēta Erdogana virzītā reforma par izstāšanos no Stambulas konvencijas. Šis ir ļoti nozīmīgs temats, jo tas tiešā mērā ietekmē Latvijas kā Eiropas Savienības dalībvalsts un Turcijas attiecības starptautiskā kontekstā. Darba izstrādes laikā autore ir secinājusi, ka Redžeps Tajips Erdogans ar veiksmīgu politisko stratēģiju un varas konsolidācijas metodēm, izmantojot polarizāciju valstī un uzrunājot konservatīvo sabiedrības daļu, ir stiprinājis un centralizējis varu AKP un savās rokās. Pieņemot konservatīvas reformas un likumprojektus, kas grauj sekulāro institūciju integritāti un darbošanās spējas, Erdogans veido antisekulārisma politiku Turcijā, kas veicina valstī pieaugošo autoritārismu.Bachelor’s thesis “Authoritarianism, Erdogan and Anti-secularism in Turkey” objective is to discover how the president of Turkey Recep Tayyip Erdoğan utilises the historical and current societal polarisation and power consolidation methods to implement conservative political reforms, furthering anti-secularism politics in Turkey, whilst undermining the integrity of secular institutions. In the bachelor’s thesis the author has analyzed Erdogans push for withdrawal of Istanbul convention. This is an important topic as it directly influences Latvia as a part of European Union and the international relations on global scale. During the development of bachelor’s thesis, the author has concluded that Recep Tayyip Erdoğan with successful political strategy, power consolidation methods and utilisation of societal polarisation has strengthened and centralised the power in the hands of Justice and Development party(AKP) and himself. Whilst adopting conservative reforms and policies Erdogan has eroded the integrity and role of secular institutions. The promotion of anti-secular politics in Turkey fosters increasing authoritarianism in Turke
Georgian Orthodoxy: Navigating the Middle Eastern Landscape
No full textThis paper explores the complex sentiments among Georgian Orthodox believers, who simultaneously exhibit unwavering allegiance to the spiritual power of former imperialistic Russia alongside discontentment due to its military aggression. The author contends that the prevailing scholarly perspective is incomplete, stemming from a Eurocentric approach, and advocates instead for a broader consideration of Georgia, along with Azerbaijan and Armenia, within the cultural milieu of the Middle East rather than the European context. In the Middle Eastern cultural sphere, characterized by Islam, distinctions between secular and religious realms are blurred—a feature similarly reflected in Georgian Orthodox Christianity. Shaped by historical encounters with Islam, Georgian Orthodoxy assimilated aspects of the dominant belief system. The Ottoman Empire, historically a significant religious and political adversary to Georgia, exerted considerable influence, reinforcing the fusion of religion and politics

Data driven assessment of the impact of upstream soil sealing on downstream floods in Flanders, Belgium
No full textSoil sealing affects the hydrological processes in a watershed by increasing the surface runoff and decreasing infiltration into the soil. Consequently, urbanization poses a significant challenge for watershed management to mitigate the accumulation of runoff downstream and the associated occurrence and severity of flood events. Hydrological models are often employed to assess the impact of land-use dynamics on flood events and, conversely, the fraction of sealed soil is a common variable in conceptual, lumped or spatially distributed, mechanistic models. However, with the availability of longer time series of observed georeferenced flooded zones (derived from satellite sensors or compiled by ad hoc observations), there is now the opportunity to assess the relationship between soil sealing and flood frequency and severity in a data-driven approach taking the meteorological conditions and landscape configuration into account.
An empirical, data-driven analysis was performed in Flanders, a highly urbanized region in Belgium parts of which are prone to flooding, to assess the impact of soil sealing on flood events using a spatially explicit archive of the flooded areas dating back to 1988. Data from this archive, along with time series of rainfall, river discharge and land use data, were collected for three middle-sized river basins, and analyzed using three methods: a linear regression and two machine learning techniques, boosted regression trees and support vector regression. The results of these analyses show that the hypothesis that more soil sealing would lead to more severe floods downstream taking into account rainfall characteristics, is only partially confirmed: there are still data limitations to overcome, which also affect the performance of spatial decision support systems.sponsorship: Fonds Wetenschappelijk Onderzoek|SB/1S01217Nstatus: Publishe
