71. Morphological dependencies : a dissertationGuy Tabachnick, 2023, doctoral dissertation Abstract: This dissertation investigates morphological dependencies: correlations between two lexically specific patterns, such as selection of inflectional affixes. Previous work has established that such correlations exist in the lexicon of morphologically rich languages (Ackerman et al., 2009; Wurzel, 1989), but has not systematically tested whether speakers productively extend these patterns to novel words. I present a series of corpus and nonce word studies—in Hungarian, Czech, and Russian—testing whether speakers vary their selection of suffixed forms of novel words based on the forms of that word that are presented to them. In all three cases, speakers vary their responses in accordance with the provided stimuli, demonstrating that they have learned and productively apply morphological dependencies from the lexicon.
I present a theoretical account of morphological dependencies that can account for my experimental results, based on the sublexicon model of phonological learning (Allen & Becker, 2015; Becker & Gouskova, 2016; Gouskova et al., 2015). In this model, speakers index lexically specific behavior with diacritic features attached to underlying forms in lexical entries, and learn generalizations over sublexicons defined as words that share a feature. These generalizations are stored as constraints in phonotactic grammars for each sublexicon, enabling speakers to learn phonological and morphological dependencies predicting words that pattern together. This model provides a unified treatment of morphological dependencies and generalizations that are phonological in nature. My studies show a wide range of learned effects, not limited to those that follow an organizational principle like paradigm uniformity. The sublexicon model assumes that speakers can learn arbitrary generalizations without restrictions, giving it needed flexibility over more restrictive models which rely on notions of morphophonological naturalness.

73. Uvular rhotic weakening in Yiddish adjectival suffixesGuy Tabachnick, 2020, published scientific conference contribution abstract Abstract: In traditional Yiddish dialects, the presence vs. absence of word-final rhotics after [ɜ] in adjectival suffixes carries a heavy functional load, making distinctions of gender, number, and case. Belk et al. (2019) note that some Yiddish speakers with uvular rhotics do not fully articulate them word-finally, endangering this crucial distinction and perhaps contributing to the loss of gender and case in the Yiddish of contemporary Hasidic communities. This study analyzes adjectival endings in publicly available recordings of for speakers with uvular rhotics. The majority of speakers generally do not produce an audible [ʀ] or [ʁ] before consonants, but the rhotic leaves its mark: for some, an underlying rhotic conditions higher F1 on the preceding vowel; others have lowered F2. F1 raising of [ɜ] can also occur when followed by the dorsal fricative [x/χ], suggesting that it is the uvularity of the rhotic that causes F1 raising; F2 lowering is limited to following rhotics, suggesting that this is a rhoticity effect. In addition, vowels followed by underlying coda rhotics are longer in duration. Results indicate that the rhotic triggers phonologized changes in the preceding vowel, while its own realization is weakened, perhaps to an approximant, and masked in the acoustic signal.

74. Recommendations for reporting equivalent black carbon (eBC) mass concentrations based on long-term pan-European in-situ observationsMarjan Savadkoohi, Marco Pandolfi, Olivier Favez, Jean-Philippe Putaud, Konstantinos Eleftheriadis, Markus Fiebig, Philip Hopke, Paolo Laj, A. Wiedensohler, Griša Močnik, 2024, original scientific article Abstract: A reliable determination of equivalent black carbon (eBC) mass concentrations derived from filter absorption photometers (FAPs) measurements depends on the appropriate quantification of the mass absorption cross-section (MAC) for converting the absorption coefficient (babs) to eBC. This study investigates the spatial–temporal variability of the MAC obtained from simultaneous elemental carbon (EC) and babs measurements performed at 22 sites. We compared different methodologies for retrieving eBC integrating different options for calculating MAC including: locally derived, median value calculated from 22 sites, and site-specific rolling regression MAC. The eBC concentrations that underwent correction using these methods were identified as LeBC (local MAC), MeBC (median MAC), and ReBC (Rolling MAC) respectively. Pronounced differences (up to more than 50 %) were observed between eBC as directly provided by FAPs (NeBC; Nominal instrumental MAC) and ReBC due to the differences observed between the experimental and nominal MAC values. The median MAC was 7.8 ± 3.4 m2/g from 12 aethalometers at 880 nm, and 10.6 ± 4.7 m2/g from 10 MAAPs at 637 nm. The experimental MAC showed significant site and seasonal dependencies, with heterogeneous patterns between summer and winter in different regions. In addition, long-term trend analysis revealed statistically significant (s.s.) decreasing trends in EC. Interestingly, we showed that the corresponding corrected eBC trends are not independent of the way eBC is calculated due to the variability of MAC. NeBC and EC decreasing trends were consistent at sites with no significant trend in experimental MAC. Conversely, where MAC showed s.s. trend, the NeBC and EC trends were not consistent while ReBC concentration followed the same pattern as EC. These results underscore the importance of accounting for MAC variations when deriving eBC measurements from FAPs and emphasizes the necessity of incorporating EC observations to constrain the uncertainty associated with eBC.

75. Contribution of black carbon and desert dust to aerosol absorption in the atmosphere of the Eastern Arabian PeninsulaMohamed M. K. Mahfouz, Gregor Skok, Jean Sciare, Michael Pikridas, M. R. Alfarra, Shamjad Moosakutty, Bálint Alföldy, Matic Ivančič, Martin Rigler, Asta Gregorič, Rok Podlipec, Griša Močnik, 2024, original scientific article Abstract: Discriminating the absorption coefficients of aerosol mineral dust and black carbon (BC) in different aerosol size fractions is a challenge because of BC's large mass absorption cross-section compared to dust. Ambient aerosol wavelength dependent absorption coefficients in supermicron and submicron size fractions were determined with a high time resolution. The measurements were performed simultaneously using identical systems at an urban and a regional background site in Qatar. At each site, measurements were taken by co-located Aethalometers, one with a virtual impactor (VI) and the other with a PM1 cyclone to respectively collect super-micron-enhanced and submicron fractions. The combined measurement of aerosol absorption and scattering coefficients enabled the particles to be classified based on their optical properties' wavelength dependence. The classification reveals the presence of BC internally/externally mixed with different aerosols. Helium ion microscopy images provided information concerning the extent of mineral dust in the submicron fraction. The determination of absorption coefficients during dust storms and non-dust periods was used to establish the absorption Ångström exponent for dust and BC. Non-parametric wind regression, potential source contribution function and back-trajectory analysis reveal major regional sources of desert dust associated with north-westerly winds and a minor local dust contribution. In contrast, major BC sources found locally were associated with south-westerly winds with a smaller contribution made by offshore emissions transported by north-easterly and easterly winds. The use of a pair of Aethalometers with VI and PM1 inlets separates contributions of BC and dust to the aerosol absorption coefficient.

78. Performance analysis of high-spectral-resolution lidar with/without laser seeding technique for measuring aerosol optical propertiesFengjia Gao, Fei Gao, Gaipan Li, Fan Yang, Li Wang, Song Yuehui, Dengxin Hua, Samo Stanič, 2024, original scientific article Abstract: High-spectral-resolution lidar (HSRL) is a powerful tool for aerosol measurements. With/without laser seeding technique in the transmitted laser, the HSRL can be distinguished as the single-longitudinal-mode (SLM) HSRL or the multi-longitudinal-mode (MLM) HSRL, and the Mach-Zehnder interferometer (MZI) with periodic transmittance function can be used as the spectral discriminator in both the SLM HSRL and MLM HSRL. To in-depth knowledge of the respective advantages of the SLM HSRL and MLM HSRL for measuring aerosol optical properties, the working principle, optimal parameter setting, and detection performance of the SLM HSRL and MLM HSRL are analyzed and discussed in detail, respectively. The working principle of the SLM HSRL and MLM HSRL indicate that the effective transmittance of MZI is the important parameter of data retrieval, the main source of retrieval uncertainties, and the key factor of MZI optical path difference (OPD) settings. To ensure that the MZI can achieve the preferable separation for aerosol Mie scattering signals and molecular Rayleigh scattering signals, the optimal OPDs of MZI are set at 165 mm and 1000 mm in the SLM HSRL and MLM HSRL from the aspects of the effective transmittance of MZI and the spectral discrimination ratio (SDR). Besides, to analyze the influence of frequency difference and divergence angle for the detection performance of HSRL, the effective transmittance of MZI and SDR are simulated and the results show that the MLM HSRL has higher requirements for the environmental parameters and the echo beam collimation than the SLM HSRL. Moreover, the HSRLs with SLM and MLM transmitted lasers are constructed in Xi'an for measuring aerosol optical properties. The preliminary measurement results show that the range square corrected signal (RSCS) of Rayleigh channel is smaller than that of Mie channel in both the SLM HSRL and MLM HSRL, while the difference between RSCS of Rayleigh channel and RSCS of Mie channel in the SLM HSRL is larger than that in the MLM HSRL, and the detection range of the SLM HSRL is lower than that of the MLM HSRL.

79. Pošta Slovenije kot prodajni kanal za trgovsko blago : diplomsko deloJanez Maček, 2024, undergraduate thesis Abstract: V časih, ko je konkurenca na trgu vse večja in pogoji poslovanja vse bolj zahtevni, je treba spremljati in prilagajati poslovanje z namenom doseganja čim boljših poslovnih rezultatov. Podjetja iščejo najboljše poslovne partnerje, ki jim na tej poti lahko najbolj pomagajo. Če razumemo lastno poslovanje in navade kupcev, lahko s tem znanjem lažje zadovoljujemo potrebe in želje tako poslovnih uporabnikov kot klasičnih kupcev. Pri izbiri poslovnih parterjev moramo biti zato pazljivi, da izbiramo parterje, ki imajo produkt ali storitev, ki jo lahko trgovec trži in prodaja, ker si jo kupci na trgu želijo in so jo pripravljeni po postavljeni ceni tudi plačati. Podjetje si prizadeva zagotoviti najboljšo uporabniško izkušnjo, ukvarja se s pridobivanjem novih strank in stremi k temu, da čim bolj zadovolji potrebe obstoječih strank, pa tudi poslovnih partnerjev.
V diplomskem delu smo z namenom natančnega prikaza prodaje storitev in blaga naredili analizo na področju prodaje, s poudarkom na stanju prodaje glede na pretekla leta. Na osnovi prodajnih rezultatov preteklih let smo opredelili vzroke za trenutno stanje in ukrepe za izboljšavo. Podali smo tudi ugotovitve, če je podjetje primeren partner za sodelovanje pri prodaji blaga in storitev z drugimi podjetji oz. poslovnimi partnerji, ter to tudi obrazložili.

80. Motivacija zaposlenih in njena povezanost z organizacijsko klimo : diplomsko deloMarija Kurdumanović, 2024, undergraduate thesis Abstract: Motivacija zaposlenih ima ključno vlogo pri povečanju produktivnosti, zadovoljstva pri delu in splošnem uspehu organizacije. Tesno je povezana z organizacijsko klimo, ki se nanaša na delovno okolje, kulturo in prakse znotraj organizacije. Namen diplomskega dela je temeljito raziskati odnos med motivacijo zaposlenih in organizacijsko klimo ter izpostaviti ključne dejavnike in njihov vpliv na uspešnost organizacije. Za razumevanje odnosa med motivacijo zaposlenih in organizacijsko klimo je ključnega pomena vstop v ustrezne teoretične okvire. Eden od takih okvirjev je Maslowa hierarhija potreb, ki nakazuje, da posameznikovo motivacijo poganja izpolnjevanje različnih ravni potreb, vključno s fiziološkimi, varnostnimi, socialnimiter spoštovanje in samoaktualizacija. Z razumevanjem teh potreb lahko organizacije ustvarijo podporno klimo, ki spodbuja motivacijo zaposlenih. Organizacijska klima močno vpliva na motivacijo zaposlenih. Pozitivna klima, ki jo zaznamujejo zaupanje, odprti komunikacijski kanali in jasni cilji, povečuje motivacijo zaposlenih. Nasprotno pa lahko negativna klima, za katero so značilni pomanjkanje podpore, hierarhične strukture in omejene možnosti za rast, močno ovira motivacijo zaposlenih. Bistvenega pomena je, da organizacije prepoznajo te vplive in sprejmejo ukrepe za spodbujanje vzdušja, ki spodbuja motivacijo.
V tem delu je bila izvedena raziskava o motivaciji zaposlenih in njeni povezanosti z organizacijsko klimo v podjetju, ki je želelo ostati anonimno. V raziskavi je sodelovalo 20 zaposlenih v raziskovalnem podjetju. Organizacijska kultura tega podjetja je dobra, motivacija pa močno vpliva na organizacijsko klimo.
