Long-term persistence, invariant time scales and on-off intermittency of fog events
2021
Abstract In this work we study different characteristics of fog long-term persistence, in events with different physical formation mechanisms. Specifically, we focus on the characterization of fog long-term persistence from observational data, by means of a Detrended Fluctuation Analysis (DFA) of its associated low-visibility time series. We analyze fog events with radiation and orographic underlying physical formation mechanisms, and identify a two-range pattern of long-term persistence. Our analysis leads to the emergence of a characteristic time, τ∗, at the crossover point between different scaling exponents in the DFA, independent of the time scale at which the fog event is studied. We …
Gaze position reveals impaired attentional shift during visual word recognition in dysfluent readers
2014
Effects reflecting serial within-word processing are frequently found in pseudo- and non-word recognition tasks not only among fluent, but especially among dyslexic readers. However, the time course and locus of these serial within-word processing effects in the cognitive hierarchy (i.e., orthographic, phonological, lexical) have remained elusive. We studied whether a subject’s eye movements during a lexical decision task would provide information about the temporal dynamics of serial within-word processing. We assumed that if there is serial within-word processing proceeding from left to right, items with informative beginnings would attract the gaze position and (micro-)saccadic eye movem…
Shaping pseudoneglect with transcranial cerebellar direct current stimulation and music listening
2015
Non-invasive brain stimulation modulates cortical excitability depending on the initial activation state of the structure being stimulated. Combination of cognitive with neurophysiological stimulations has been successfully employed to modulate responses of specific brain regions. The present research combined a neurophysiological pre-conditioning with a cognitive conditioning stimulation to modulate behavior. We applied this new state-dependency approach to investigate the cerebellar role in musical and spatial information processing, given that a link between musical perception and visuo-spatial abilities and a clear cerebellar involvement in music perception and visuo-spatial tasks have …
The self-reported stress and stressors in tram and long-haul truck drivers
2022
Work stress may compromise professional drivers’ health and driving capacity. Differences between driver groups in terms of on-duty stress are understudied. Therefore, we examined self-reported stress (Stockholm University Stress Scale) of shift-working tram and long-haul truck drivers (n = 75) across 2–3 weeks. Furthermore, stressors were self-reported retrospectively and categorised as related to the job, driving conditions, personal, or other causes. Stress levels were generally low, but moderate to high stress (≥6) was more frequently reported among the tram drivers. Stressors related to the job (54%) and driving conditions (19% of all shifts) were frequently reported among the tram and…
Seismic stratigraphy of upper Quaternary shallow-water contourite drifts in the Gulf of Taranto (Ionian Sea, southern Italy)
2018
Abstract The occurrence of articulated seafloor morphology over continental shelf-upper slope environments, may result in a significant change in the patterns and intensity of basin-scale thermohaline circulation during eustatic sea-level fluctuations. These changes may cause, in turn, erosion, deposition and/or transport of sediments at the seafloor, to form shallow-water contourite drifts. Here we investigate this process in the NW sector of the Gulf of Taranto (Ionian Sea) during and following the Last Glacial Maximum (LGM), by integrating multibeam bathymetric data, ultra-high resolution seismic-reflection data and gravity core data. Sea level fall caused subaerial exposure of the summi…
Crystal and molecular structure studies of (Z)-N-methyl-C-4-substituted phenyl nitrones by XRD, DFT, FTIR and NMR methods
2017
Abstract (Z)-N-methyl-C-4-substituted phenyl nitrones –O+N(Me)=C(H)R (Z-2a R = 4-ClC6H4, Z-2b R = 4-NO2C6H4, Z-2c R = 4-CH3OC6H4) were synthesized and characterized by elemental analyses, FTIR, 1H, 13C and DEPT-135 NMR spectroscopy and also by single crystal X-ray diffraction (in the case of Z-2a and Z-2b). The geometries of the nitrone molecules Z-2a, Z-2b and Z-2c and their E-isomers; (E)-N-methyl-C-4-chlorophenyl nitrone E-2a, (E)-N-methyl-C-4-nitrophenyl nitrone E-2b and (E)-N-methyl-C-4-methoxyphenyl nitrone E-2c were optimized using density functional theory (DFT) at the B3LYP/6-311++G(d,p) level of theory. The theoretical vibrational frequencies obtained by DFT calculations are in go…
A study of active ownership through board representation by norwegian private equity actors in the norwegian population of portfolio company investme…
2013
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2013 This thesis focuses on the indirect drivers of value creation in private equity, through a study of corporate governance mechanisms employed by the major Norwegian PE actors in a population of Norwegian portfolio company investments. More specifically, it focuses on board representation by PE actors in the venture capital and buyout portfolio company investments. For this study, data pertaining to debt/equity, return on assets and portfolio company size has been collected for the current active population of portfolio company investments for the period (t-1) (one year before PE investment) as well as for (t+1) (one year …
Fortsatt drift: Regnskapsrapportering i konkursrammede små aksjeselskap : En studie av hvordan det rapporteres om fortsatt drift i forkant av konkurs…
2020
Master's thesis in Accounting and auditing (BE508) Hvert år går flere tusen små aksjeselskap konkurs i Norge. I forkant av konkursene avlegges som oftest etrevidert årsregnskap fra foregående regnskapsperiode. I disse regnskapene er selskapet pliktet til å gjennomføre og rapportere om selskapets forutsetning om fortsatt drift, og dersom den ikke er til stede, å legge forutsetning om avvikling, til grunn for utarbeidelsen av regnskapet.Studien omhandlerdet grunnleggende regnskapsprinsippet forutsetningen om fortsatt drift. Hovedsakelig går oppgaven ut på å kartlegge hvordan forutsetningen blir behandlet i praksis. Dette studeresgjennom to forskningsspørsmål, hvor forutsetningens to mulige fo…
Revisorskifte i teori og praksis : Hva kan revisor gjøre for å beholde eksisterende og tiltrekke seg nye revisjonsklienter?
2021
Master's thesis in Accounting and auditing (BE508) Revisors rolle som allmennhetens tillitsperson er sterkt knyttet til brukere av selskapers regnskap, men hvordan er revisors rolle i samarbeidet med revisjonsklientene? Den største utfordringen for revisjonsselskap er å beholde eksisterende og tiltrekke seg nye revisjonsklienter. Jeg ønsket å finne ut om det er noe revisor kan gjøre for å redusere denne utfordringen. Med spesifikke faktorer som pris, kommunikasjon og bransjekompetanse hos revisor i bakhodet forsøker denne oppgaven å besvare følgende problemstilling: Hva kan revisor gjøre for å beholde eksisterende og tiltrekke seg nye revisjonsklienter? Studiens teoretiske rammeverk består …
Complementary methods assessing short and long-term prey of a marine top predator ‒ Application to the grey seal-fishery conflict in the Baltic Sea.
2019
The growing grey seal (Halichoerus grypus) population in the Baltic Sea has created conflicts with local fisheries, comparable to similar emerging problems worldwide. Adequate information on the foraging habits is a requirement for responsible management of the seal population. We investigated the applicability of available dietary assessment methods by comparing morphological analysis and DNA metabarcoding of gut contents (short-term diet; n = 129/125 seals, respectively), and tissue chemical markers i.e. fatty acid (FA) profiles of blubber and stable isotopes (SIs) of liver and muscle (mid- or long-term diet; n = 108 seals for the FA and SI markers). The methods provided complementary inf…
