91. Origins of fine structure in DNA melting curvesArevik V. Asatryan, Albert S. Benight, Artem Badasyan, 2024, izvirni znanstveni članek Opis: With the help of the one-dimensional random Potts-like model, we study the origins of fine structures observed on differential melting profiles of double-stranded DNA. We theoretically assess the effects of sequence arrangement on DNA melting curves through the comparison of results for random, correlated, and block sequences. Our results re-confirm the smearing out of the fine structure with the increase in chain length for all types of sequence arrangements and suggest that the fine structure is a finite-size effect. We have found that the fine structures on melting curves of chains comprised of blocks with correlations in sequence are more persistent, probably because of increased sequence disorder the blocks introduce. Many natural DNAs show a well-expressed fine structure of melting profiles. Our results for block sequences may suggest the existence of such sequence motifs in natural DNA sequences.

94. Promoting the use of open educational resources to improve teaching and learning of science subjects in secondary schools in Tanzania : master's thesisLucian Vumilia Ngeze, 2024, magistrsko delo Opis: A number of challenges have hindered the integration of Open Educational Resources (OERs) in schools from developing countries. The rate of adoption of OERs in teaching and learning in schools in Tanzania is low. This research focused on capacity of secondary school science teachers on creating and adapting open educational resources to improve the teaching and learning of science subjects. The research used a Design-based Research methodology to achieve research objectives.
Results show that challenges such as lack of ICT devices, poor Internet connection, network accessibility issues, unstable power supply and large class sizes hindered the integration of OER in the teaching of science subjects. As teachers created OERs, they stated factors such as levels of the learners, developing engaging content, simple and self-explanatory content, alignment with learning objectives and relevancy of OER as initial considerations they considered when creating OERs. It was important to investigate the change in teachers’ attitude towards the use of OER in teaching science subjects OER creation ability, OER in teaching, teaching improvements, increased teaching resources, and application of skills.
It was concluded that regular teacher professional development programmes must be set to support school teachers in using OERs to improve teaching and learning and in creating OER for teaching. Engaging with relevant government bodies is encouraged to ensure that more teachers are involved in such developed online courses.

Kongresnik John Blatnik v boju za državljanske pravice v ZDAMilan Mrđenović, Matjaž Klemenčič, 2024, izvirni znanstveni članek Opis: Avtorja v prispevku obravnavata delovanje Johna Blatnika, ameriškega kongresnika slovenskega porekla v predstavniškem domu, med letoma 1963 in 1964, ko so sprejemali temeljni zakonski predlog o državljanskih pravicah, ki je odpravil formalno diskriminacijo temnopoltih Američanov. V prispevku je povzeta korespondenca med Blatnikom in volivci 8. kongresnega okraja v Minnesoti, kjer je živelo veliko slovenskih Američanov. Avtorja na kratko povzameta tudi zgodovino rasne diskriminacije v ZDA.

97. Understanding the in-situ transformation of ▫$Cu_xO$▫ interlayers to increase the water splitting efficiency in NiO/n-Si photoanodesChao Feng, Zhi Liu, Huanxin Ju, Andraž Mavrič, Matjaž Valant, Jie Fu, Beibei Zhang, Yanbo Li, 2024, izvirni znanstveni članek Opis: The buried interface tens of nanometers beneath the solid-liquid junction is crucial for photocarrier extraction, influencing the overall efficiency of photoelectrochemical devices. Precise characterization of the interfacial properties is essential for device optimization but remains challenging. Here, we directly probe the in situ transformation of a CuxO interlayer at the NiO/n-Si interface by hard X-ray photoelectron spectroscopy. It is found that Cu(I) in the CuxO interlayer gradually transforms to Cu(II) with air exposure, forming an energetically more favorable interface and improving photoanode’s efficiency. Based on this finding, a reactive e-beam evaporation process is developed for the direct deposition of a CuO interlayer, achieving a half-cell solar-to-hydrogen efficiency of 4.56% for the optimized NiO/CuO/n-Si heterojunction photoanode. Our results highlight the importance of precision characterization of interfacial properties with advanced hard X-ray photoelectron spectroscopy in guiding the design of efficient solar water-splitting devices.

98. Another look at *numeral N-lAr : lecture at the Boğaziçi University, Department of Linguistics, Istanbul, Turkey, June 11th 2024Elena Guerzoni, 2024, predavanje na tuji univerzi Opis: In this talk I will present work in progress that I am conducting in collaboration with Furkan Dikmen and Penka Stateva. In this study, we develop a novel account for the ban of Turkish -lAr with numerals. This view builds on the pragmatic theories of the interpretation of the plural as an anti-singularity inference (see Sauerland 2003, Spector 2007, and Sauerland 2008) and presents the following advantages over Martí (2020)’s and Scontras (2022)’s previous accounts: it preserves the “at least” interpretation of Turkish numerals and at the same time it predicts the lack of plurality inferences in DE contexts, first reported in Sağ 2019.

99. When tense shifts expressive presuppositions: hani and monstrous semantics : lecture at the Department of Comparative and General Linguistics, Linguistic Circle, University of Ljubljana, June 3rd 2024Furkan Dikmen, Elena Guerzoni, Ömer Demirok, 2024, druga izvedena dela Opis: I will present a study I conducted with Furkan Dikmen and Ömer Demirok on the semantic and pragmatic properties of the Turkish ‘discourse partıcle’ hani. On the one hand, the function of hani is merely pragmatic, on the other hand, it is subject to the truth-conditional effect of other constituents at LF. In this study, we introduce the first formal semantic and pragmatic treatment of clauses containing hani. Unlike previous accounts (see Erguvanlı-Taylan (Studies on Turkish and Turkic languages; proceedings of the ninth international conference on Turkish linguistics, 133–143, 2000), Akar et al. (Discourse meaning, 57–78, 2020), and Akar and Öztürk (Information-structural perspectives on discourse particles, 251–276, 2020), we claim that hani can have one of the following two major pragmatic functions: making salient a proposition in the Common Ground or challenging one in a past Common Ground, therefore requiring a Common Ground revision. Despite its variety of occurrences, we argue that hani has a uniform interpretation and provide a compositional analysis of the different construals that it is associated with. Furthermore, we show that a formally explicit and accurate characterization of hani-clauses requires operating on indexical parameters, in particular the context time. Therefore, if our proposal is on the right track, hani clauses may provide indirect empirical evidence in favour of the existence of “monstrous” phenomena, adding to the accumulating cross-linguistic evidence in this domain (see Schlenker in Linguistics and Philosophy 26(1):29–120, 2003 and much work since then). The definition of monsters is intended as in Kaplan (Themes from Kaplan, 481–563, 1989).

100. Stress and morphology in the Italian verbsElena Guerzoni, 2024, druge monografije in druga zaključena dela Opis: In this paper I present an analysis of stress in Italian verbs. A preliminary observation reveals that
inflection affects stress position on verbs in an apparently unpredictable fashion. Although, at first
sight, the variability of stress placement in Italian verbs seems to preclude a systematic account, this
paper shows that once the morphological complexity of verbs is factored in, it is in fact the one and
the same algorithm that assigns stress in this entire word class.
