Artificial intelligence in journalism
Get PDFV diplomskem delu je obravnavana uporaba umetne inteligence v novinarstvu, s poudarkom na spremembah, ki jih ta orodja prinašajo v uredniške procese. Na podlagi pregleda literature so bili izpostavljeni ključni trendi, kot so avtomatizacija nalog, podpora pri delu s podatki in prilagajanje vsebin, skupaj z etičnimi in regulativnimi izzivi. Empirični del temelji na anketi med študenti medijskih študij, ki bodo v prihodnje soustvarjali novinarsko okolje. Ugotovljeno je bilo, da so ti pogosti, a povprečni uporabniki umetne inteligence. Ta je ocenjena kot koristno orodje, a je bilo poudarjeno, da mora odgovornost za ustvarjene vsebine ostati pri novinarju, ki orodje uporablja.This thesis examines the use of artificial intelligence in journalism, focusing on the changes these tools bring to editorial processes. A review of the literature highlights key trends such as task automation, data support, and content adaptation, along with ethical and regulatory challenges. The empirical part is based on a survey among media studies students who will co-create the journalistic environment in the future. Findings show that they are frequent but average users of artificial intelligence. It is considered a useful tool, while it was emphasized that responsibility for the created content must remain with the journalist who uses it

The influence of milling parameters on zeolite properties and the synthesis of magnetic-zeolite nanocomposites
Get PDFMagnetni nanodelci (MND) so že dosegli široko uporabo v biomedicinskih aplikacijah, diagnostiki, mehaniki, katalizi in sanaciji okolja. Napredek v razvoju tehnologije je omogočil združitev MND z drugimi materiali, kar imenujemo nanokompozit. Nanokompozit je material, ki ima dimenzije manjše od 100 nm, ter izraža združene lastnosti mešanih materialov. V diplomski nalogi smo sintetizirali magnetno-zeolitni nanokompozit, material, ki združuje lastnosti zeolitov in MND. MND smo sintetizirali z metodo koprecipitacije oz. s soobarjalno metodo. Zeolita 4A in 13X smo mleli v planetarnem krogličnem mlinu v različnih masnih razmerjih in pri različnih časih. S spreminjanjem parametrov smo ugotavljali, katera kombinacija parametrov poda najboljše rezultate za sintezo magnetno-zeolitnega nanokompozita. Z mletjem smo želeli dobiti čim večjo površino zeolita, saj ima takrat največ aktivnih mest, na katera se bodo vezali MND. Vzorce smo analizirali s termogravimetrično metodo (TGA), dinamičnim sipanjem svetlobe (DLS), infrardečo spektroskopijo s Fourierjevo transformacijo (FTIR) in Brauner-Emmett-Tellerjevo metodo (BET).Magnetic nanoparticles (MNPs) have already achieved widespread use in biomedical applications, diagnostics, mechanics, catalysis and environmental remediation. Advances in technology have enabled the combination of MNPs with other materials, resulting in what is known as a nanocomposite. A nanocomposite is a material with dimensions smaller than 100 nm and exhibits the combined properties of constituent materials. In our thesis, we synthesized a magnetic-zeolite nanocomposite, a material with the properties of zeolites and MNPs. MNPs were synthesized using the coprecipitation method. Zeolites 4A and 13X were ground in a planetary ball mill using different mass ratios and grinding times. By changing the parameters, we determined which combination yields the best results for synthesizing the magnetic-zeolite nanocomposite. The goal of grinding was to obtain the largest possible surface area of zeolite, as this provides the most active sites for MNP binding. The samples were characterized with thermogravimetric analysis (TGA), dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FTIR) and Brauner-Emmett-Teller (BET) method

Finally, the advantages and disadvantages of the libraries were highlighted and recommendations for their use were provided
Principles and criteria for planning bicycle lanes
Get PDFMagistrsko delo obravnava načrtovanje kolesarskih pasov kot ključni dejavnik za varno in učinkovito kolesarsko infrastrukturo v urbanih okoljih. Osnovni namen dela je bil opredeliti načela in kriterije za načrtovanje kolesarskih pasov, ki omogočajo izboljšanje prometne varnosti in uporabniške izkušnje. Zaradi okoljskih, zdravstvenih in prometnih izzivov kolesarjenje postaja pomembna alternativa motoriziranemu prometu, vendar zahteva ustrezno in premišljeno načrtovano infrastrukturo. V okviru raziskave smo pregledali domačo in tujo strokovno literaturo, ki zajema tehnične smernice, prometno varnost in uporabniške potrebe pri načrtovanju kolesarskih pasov. Ta pregled je omogočil vpogled v različne pristope in dobre prakse ter oblikovanje teoretične podlage za nadaljnjo analizo. Analiza stanja v Sloveniji kaže, da je kolesarska infrastruktura pogosto neustrezno načrtovana, kar zmanjšuje njeno varnost in uporabnost. Na primeru ceste v Rošpoh smo identificirali ključne pomanjkljivosti obstoječe kolesarske infrastrukture, zlasti neustrezno horizontalno prometno signalizacijo, kot so zbledene ali manjkajoče talne označbe. Za podrobnejšo presojo smo analizirali odsek Vrbanske ceste proti drevoredu ter Smetanovo ulico v Mariboru, kjer so vzpostavljeni pomožni kolesarski pasovi. Z uporabo kombinacije metod — analiza dokumentacije, terensko opazovanje, statistična obdelava podatkov in anketiranje kolesarjev na Smetanovi ulici — smo pridobili celovit vpogled v trenutno stanje in prepoznali ključne težave. Anketa je posebej osvetlila uporabniško zaznavo varnosti in udobja. Na podlagi zbranih rezultatov smo oblikovali tehnične in prostorske predloge za izboljšave, ki pomembno prispevajo k večji prometni varnosti ter spodbujajo trajnostno mobilnost.The master’s thesis addresses the design of bicycle lanes as a key factor for safe and efficient cycling infrastructure in urban environments. The primary aim of the work was to define the principles and criteria for designing bicycle lanes that improve traffic safety and user experience. Due to environmental, health, and traffic challenges, cycling is becoming an important alternative to motorized transport, but it requires appropriate and thoughtfully planned infrastructure. Within the research, we reviewed domestic and international professional literature covering technical guidelines, traffic safety, and user needs in bicycle lane design. This review provided insight into various approaches and best practices and helped establish a theoretical foundation for further analysis. An analysis of the situation in Slovenia shows that cycling infrastructure is often inadequately planned, reducing its safety and usability. In the case of Rošpoh Road, we identified key deficiencies in the existing cycling infrastructure, particularly inadequate horizontal traffic signage, such as faded or missing road markings. For a more detailed assessment, we analyzed a section of Vrbanska Street toward the tree-lined avenue, as well as Smetanova Street in Maribor, where auxiliary cycle lanes are in place. By applying a combination of methods—document analysis, field observation, statistical data processing, and a survey of cyclists on Smetanova Street—we obtained a comprehensive insight into the current state and identified the main issues. The survey specifically highlighted users’ perceptions of safety and comfort. Based on the collected results, we developed technical and spatial proposals for improvements that significantly contribute to enhanced traffic safety and the promotion of sustainable mobility
Izzivi prevajanja metafor v slovenskih posodobljenih prevodih kratkih zgodb Edgarja Allana Poeja
Get PDFThe article focuses on translations of metaphors, a unique aesthetic and poetic figure that requires special attention and accurate rendering in a literary translation. When translating metaphors, the translator should understand and preserve the meaning and the aesthetic component of the metaphors. The study discusses the rendering of metaphors in translations and re-translations of three short stories by Edgar Allan Poe: “The Gold Bug,” translated by Boris Rihteršič in 1935, and Jože Udovič in 1960“The Pit and the Pendulum,” translated by Rihteršič in 1935 and by Udovič in 1972, and “The Fall of the House of Usher,” translated by Zoran Jerin and Igor Šentjurc (1952), and by Udovič in 1972. In gothic fiction, Poe established himself as a master of metaphors, which he used with astonishing fluency and precision. The results of the analysis demonstrate how and in which way Slovene translators rendered metaphors in the short stories of one of the greatest writers of gothic fiction, and what strategies they used to preserve Poe’s unique, dark, and delirious metaphorical style.V prispevku so obravnavani prevodi metafor iz izvirnega v ciljni jezik. Metafora je edinstvena estetska in poetološka figura, ki v književnem prevodu zahteva posebno pozornost in obravnavo. Pri prevajanju metafor mora prevajalec razumeti in ohraniti pomen ter estetske elemente besedila. Z izbrisom, parafraziranjem ali napačno interpretacijo metafor besedilo izgubi svoj ključni element. Pričujoča študija obravnava metafore v prevodih in posodobljenih prevodih treh kratkih zgodb Edgarja Allana Poeja: »Zlatega hrošča« v prevodu Borisa Rihteršiča leta 1935 in posodobljenem prevodu Jožeta Udoviča leta 1960»Vodnjaka in nihala«, ki sta jo prevedla Rihteršič leta 1935 in Udovič leta 1972, ter »Konca Usherjeve hiše« v prevodu Zorana Jerina in Igorja Šentjurca (1952) ter Udoviča leta 1972. Poe se je uveljavil kot mojster metafor, ki jih je v besedilu uporabljal z izjemno spretnostjo in natančnostjo. Primerjava prevodov razkriva, kako so se slovenski prevajalci lotili prevajanja metafor v kratkih zgodbah enega najodličnejših pisateljev žanra gotske grozljive zgodbe, razvidne pa so tudi strategije, s katerimi so ohranili Poejev edinstven, temačen in izjemen metaforični slog
Blockchain technology implementation for traceability in the food supply chain – case research
Get PDFFood supply chains are evolving into coordinated systems, prompting competition between companies and entire supply networks. In this context, Short Food Supply Chains (SFSCs) have emerged as a response to public concerns about food sourcing and handling. Defined by the EU as systems involving few economic actors committed to local development and close producer-consumer relations, SFSCs present both opportunities and challenges. Among key challenges are identity management, transparency, and security. Blockchain technology, introduced shortly after SFSCs gained attention, offers promising solutions by enhancing traceability and linking product information with physical flows. This chapter explores the role of blockchain in addressing traceability challenges and presents a practical case of its application in SFSCs
Optional protocol on the sale of children, child prostitution and child pornography – criminalising practices including and exceeding exploitation and abuse of children
Get PDFThe 2000 Optional Protocol to the Convention on the Rights of the Child on the sale of children, child prostitution and child pornography is considered one of the most widely ratified international treaties, promulgating the incrimination of customers and intermediaries in cases of sexual and other forms of exploitation of children. This chapter highlights its strengths and limitations. Special emphasis is placed on provisions prohibiting and criminalising practices covered under the Protocol, particularly concerning topical and divisive issues such as commercial surrogacy, virtual pornography and the maximum age of protection under the Optional Protocol. Moreover, topics such as sanctions and other substantive issues, jurisdiction, freezing and confiscation of assets, extradition and further instruments of mutual legal assistance, rights of child victims and preventive measures are briefly addressed. Where applicable, the contrast between the Convention and the Optional Protocol is emphasised, as the drafters of the latter opted for a more welfarist approach. This implies that the Optional Protocol drastically limits children’s agency to, for example, using explicit sexual materials in the context of sexting as a part of their sexual development. Recognising this issue, the authors argue against an unreasonably extensive interpretation of the Protocol’s provisions which concern practices that far exceed the exploitation or abuse of children
The role of cognitive strategies in the regulation of food craving
Get PDFOsrednja tema pričujoče naloge je regulacija hrepenenja po hrani. V današnjem času, kjer se soočamo z epidemijo debelosti, je to ena izmed tem, ki lahko pomaga osvetliti ta problem. Eden izmed dejavnikov, ki še posebej prispeva k razvoju debelosti, je okolje, v katerem danes živimo, t. i. obesogeno okolje. V obesogenem okolju je prisotno obilje prehranskih dražljajev, zato je pomembno razumeti, kako se posamezniki nanje odzivajo. Eden izmed odzivov na prehranske dražljaje je hrepenenje po hrani, ki ga lahko posamezniki regulirajo. Kot učinkovita intervencija v dosedanji literaturi izstopajo kognitivne strategije regulacije, ki se lahko prilagodijo posamezniku in njegovem okolju. V magistrski nalogi smo želeli raziskati, na kakšen način se spreminja hrepenenje po hrani glede na uporabo različnih kognitivnih strategij. Dodatno smo preverili povezavo med hrepenenjem in z dogodkom povezanimi potenciali (ERP), ki smo jih pridobili s pomočjo EEG. Posebej smo se osredotočili na LPP, ki odraža motivacijsko pomembnost dražljaja, pojavi pa se 400 ms po njegovi predstavitvi. Kot en dejavnik, povezan s spremembami amplitud LPP, nas je zanimala tudi samoporočana vznemirjenost.
Udeleženci (N = 57) so se udeležili eksperimenta, med katerim so opazovali slike visokokalorične hrane med snemanjem signalov EEG. Prejeli so 4 navodila, ki hkrati predstavljajo 4 eksperimentalne pogoje. Dva sta brez kognitivne regulacije (ZDAJ in GLEJ), preostala dva pa sta pogoja kognitivne regulacije in vsebujeta razmišljanje o dolgoročnih negativnih posledicah uživanja visokokalorične hrane (KASNEJE NEGATIVNO) oz. dolgoročnih pozitivnih posledicah izogibanja visokokalorični hrani (KASNEJE POZITIVNO).
Analiza podatkov je pokazala, da je bilo samoporočano hrepenenje po hrani znatno nižje v pogojih, kjer je bila prisotna kognitivna regulacija v primerjavi s pogoji brez regulacije hrepenenja. Preverili smo še, ali se zgodnje amplitude LPP spreminjajo glede na uporabo kognitivnih strategij, vendar nismo zaznali sistematičnih sprememb. Dodatno smo preverili povezavo med zgodnjimi amplitudami LPP in samoporočano vznemirjenostjo, vendar ni bilo značilnih korelacij. Z moderacijsko analizo smo preverili, ali vznemirjenost moderira odnos med zgodnjimi amplitudami LPP in samoporočanim hrepenenjem. Ta povezava je bila statistično značilna samo v pogoju GLEJ, kjer smo ob višjem nivoju vznemirjenosti zasledili močnejšo povezavo med samoporočanim hrepenenjem in spremembami zgodnjih amplitud LPP. Naši rezultati podpirajo kognitivno regulacijo kot učinkovito strategijo za obvladovanje (samoporočanega) hrepenenja po visokokalorični hrani. Hkrati pa poudarjajo potrebo po nadaljnjih raziskavah, ki bi sistematično raziskale dinamiko med subjektivnimi doživljanji in nevrološkimi procesi, s čimer bi lahko razvili bolj natančne in ciljno usmerjene intervencije.The central theme of this thesis is the regulation of food cravings. In today\u27s world, as we are faced with an obesity epidemic, this is one of the topics that can help shed light on this problem. One of the factors that particularly contributes to the development of obesity is the environment in which we live today, the so-called obesogenic environment. In an obesogenic environment, there is an abundance of food stimuli, so it is important to understand how individuals respond to them. One of the responses to food stimuli is food craving, which individuals can regulate. In existing literature, cognitive regulation strategies that can be adapted to the individual and their environment stand out as an effective intervention. In this master\u27s thesis, we wanted to investigate how food cravings change depending on the use of different cognitive strategies. Additionally, we examined the relationship between cravings and event-related potentials (ERPs), obtained using EEG. We focused specifically on the LPP, which reflects the motivational significance of a stimulus and occurs 400 ms after its presentation. We were also interested in self-reported arousal as a factor associated with changes in LPP amplitude.
Participants (N = 57) took part in an experiment, during which they viewed images of high-calorie foods while their EEG signals were recorded. They received four sets of instructions, which also represented four experimental conditions. Two were without cognitive regulation (NOW and LOOK), while the other two were conditions of cognitive regulation, and involved thinking about the long-term negative consequences of consuming high-calorie foods (LATER NEGATIVE), or the long-term positive consequences of avoiding high-calorie foods (LATER POSITIVE).
Data analysis showed that self-reported food cravings were significantly lower in conditions where cognitive regulation was present compared to conditions without craving regulation. We also examined whether early LPP amplitudes varied depending on the use of cognitive strategies, but did not detect any systematic changes. Additionally, we examined the relationship between early LPP amplitudes and self-reported arousal, but found no significant correlations. We used a moderation analysis to check whether arousal moderates the relationship between early LPP amplitudes and self-reported craving. This relationship was statistically significant only in the LOOK condition, where we observed a stronger relationship between self-reported craving and changes in early LPP amplitudes at higher levels of arousal.
Our results support cognitive regulation as an effective strategy for managing (self-reported) cravings for high-calorie foods. At the same time, they highlight the need for further research that systematically investigates the dynamics between subjective experiences and neurological processes, which could lead to the development of more precise and targeted interventions
