Microgeographic Variation of Genetic Polymorphism in Argyresthia mendica (Lep.: Argyresthiidae)
1988
Field studies on the genetic structure of populations show a considerable amount of heterogeneity in space and time. In many cases, these heterogeneities can be related to structures in the environment, such as properties of soil, availability of special food resources, topographic conditions or climate. In other cases the genetic structure can be explained by properties of the plant and animal species under study, e.g. ability and speed of migration and colonization (Karlin and Nevo 1976; Endler 1977; Nevo 1978; Nevo and Yang 1979; Nevo et al. 1981; Seitz and Komma 1984; Wohrmann 1984).
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…
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 …
The Lefkada barrier and beachrock system (NW Greece) — Controls on coastal evolution and the significance of extreme wave events
2012
Abstract The Lefkada–Preveza coastal zone, NW Greece, is characterised by an active barrier system and related extensive beachrock sequences. Besides the gradual coastal processes of longshore drift and spit evolution, the presence of active tectonics and the occurrence of tsunamis have been documented in previous studies and are part of the coastal geomorphological system. In this paper, we present the results of detailed multi-proxy sedimentological and geomorphological investigations carried out along the northern part of the barrier system and in back-beach positions. Our findings suggest that extreme wave events contributed to coastal and environmental changes and involved temporary br…
Beyond budgeting since inception: what is the status?
2017
Master's thesis Business Administration BE501 - University of Agder 2017 The Beyond Budgeting idea as developed by Hope and Fraser (1997) has been in existence for almost twenty years, yet, the research community still has divergent views on whether the concept is a better management accounting tool for organizations’ management control system or not. Also, whether it has received attention in research community like other management accounting tools such as Traditional Budgeting and Balanced Scorecard. On this notion, this study is developed to investigate the status of the research discourse on the concept to gain relevant knowledge. Inspired by Scapens and Bromwich (2001) and built on Ac…
Genetic relationships between sympatric and allopatric Coregonus ciscoes in North and Central Europe
2021
Abstract Background Sympatric speciation along ecological gradients has been studied repeatedly, in particular in freshwater fishes. Rapid post-glacial ecological divergence has resulted in numerous endemic species or ecologically distinct populations in lakes of the temperate zones. Here, we focus on the Baltic cisco (Coregonus albula) complex, to study the genetic similarity among two pairs of sympatric autumn- and spring-spawning populations from post-glacial German Lakes Stechlin and Breiter Luzin. For comparison, we included a similar pair of sympatric populations from the Swedish Lake Fegen. We wanted to explore potential genetic similarities between the three sympatric cisco populati…
Crossing Borders. Concepts and Practices for a New Planetary Dimension
2020
The essay takes into account some categories and practices of colonial relations by considering both domination and subjectification processes and handles the concept of border and the complex dynamics of crossing, mobility, diaspora, and hybridization. The critical analysis of the hierarchical order of the world highlights the ways in which the relations between non-homogeneous elements produce conflict and assimilation practices, but also contaminations and inclusion. By assuming the "colonial" as a precarious concept, the essay stresses the discursive aspects of dominion but also the government, counter-conducts, and resistances, without forecloses the persistence of the epistemological …
Large eddy simulation model for wind-driven sea circulation in coastal areas
2013
Abstract. In the present paper a state-of-the-art large eddy simulation model (LES-COAST), suited for the analysis of water circulation and mixing in closed or semi-closed areas, is presented and applied to the study of the hydrodynamic characteristics of the Muggia bay, the industrial harbor of the city of Trieste, Italy. The model solves the non-hydrostatic, unsteady Navier–Stokes equations, under the Boussinesq approximation for temperature and salinity buoyancy effects, using a novel, two-eddy viscosity Smagorinsky model for the closure of the subgrid-scale momentum fluxes. The model employs: a simple and effective technique to take into account wind-stress inhomogeneity related to the …
