Inverse analysis of viscoelastic stresses in embryo development

The project analyses the set of plausible stresses that generate the observed deformations of central nervous system in Drosophila during the condensation process. From a set of planar displacements fields measured at different instants, the student will compute stress profiles on 3D geometries, modelled with finitie elements. A customised Matlab code will be employed and adapted to the problem at hand. Different rheological hypothesis will be tested: elastic and viscoelastic models of Maxwell and Kelvin types. From the analysis and post-process of results, suitable material parameters and models will be proposed for the embryonic tissue.Incomin

Identifying factors affecting consumers purchase incidence at retail trade shows

The purpose of this article is to examine variables influencing purchase incidences at retail trade shows. To this end, retailer and consumer related antecedent variables are proposed. The retailer related variables are represented by store environmental cues of sales staff services, store atmosphere and product assortment. The consumer related variables are represented by impulse buying tendency and perceived time pressure. Drawing on relevant literature, hypotheses are developed to link each of these variables to purchase incidence. Data were collected using questionnaire from shoppers (N=95) at a large retail trade show. The hypotheses were tested using partial least square path modeling. The findings indicate that consumers’ favorable evaluation of retailers’ sales staff services, store atmosphere and product assortment led to more purchase incidences. The findings about the consumer related variables indicate that impulse buying tendency led to more purchase incidences whereas perceived time pressure led to fewer purchase incidences. Drawing on these results, several implications for practice and research are suggested

Managing Trade Show Campaigns: Why Managerial Responsibilities Matter?

Author's accepted version (post-print).This is an Accepted Manuscript of an article published by Taylor & Francis in Journal of Promotion Management on 10/05/2012, available online: http://www.tandfonline.com/10.1080/10496491.2012.668434.This article examined the relationship between managerial responsibilities for important trade show tasks and the marketing performance of exhibiting firms. Drawing theoretical insights from the functionalist perspective of managerial roles and organizational role theory, this article proposed and validated theory based, multiple, task-managerial responsibility linkages using a large international b2b trade show as a context. The empirical results indicated that the marketing performance of exhibiting firms was enhanced when (a) middle managers were assigned the trade show objective setting task, (b) lower and middle managers were involved in the trade show selection decision and (c) lower managers executed the booth management task. The paper concluded by discussing the theoretical and practical implications of these findings

Power budget equations and calibration factors for fish abundance estimation using scientific echo sounders and sonar systems

-Acoustic methods used in fish abundance estimation constitute a key part of the analytic assessment that makes the basis for abundance estimation of marine resources. The methods rely on power-budget equations and calibrated systems. Different formulations of power-budget equations and calibration factors have been proposed for use in scientific echo sounder and sonar systems. There are unresolved questions and apparent inconsistencies in prior literature related to this field. A generic (instrument independent) and unifying theory is presented that attempts to explain the different power-budget and calibration factor formulations proposed and used in prior literature, and how these are mutually related. Deviations and apparent inconsistencies in this literature appear to be explained and corrected. This also includes different (instrument specific) formulations employed in important modern scientific echo sounder systems, and their relationship to the generic theory of abundance estimation. Prior literature is extended to provide more complete power-budget equations for fish abundance estimation and species identification, by accounting for echo integration, electrical termination, and the full range of electrical and acoustical echo sounder parameters. The expressions provide a consistent theoretical basis for improved understanding of conventional methods and instruments used today, also enabling improved sensitivity and error analyses, and correction possibilities

Importance Performance Analysis as a Trade Show Performance Evaluation and Benchmarking Tool

Author's accepted version (post-print).The purpose of this study is to introduce importance performance analysis as a trade show performance evaluation and benchmarking tool. Importance performance analysis considers exhibitors’ performance expectation and perceived performance in unison to evaluate and benchmark trade show performance. The present study uses data obtained from exhibitors of an international trade show to demonstrate how importance performance analysis can be used to evaluate and benchmark trade show performance. The study discusses the normative and the theoretical implications of the proposed method

Systematic Risk Factors at Oslo Stock Exchange

We construct five systematic risk factors for the Oslo Stock Exchange over the sample period of 1991 to 2010: an overall market factor, and factors related to firm size, book-tomarket equity, momentum, and leverage and margin constraints. We find evidence of a continuation of short-term returns and significant positive differential returns for book-tomarket equity. There appears to be no positive relationship between beta estimated and subsequent returns, which is contradictory to CAPM. Also, there is no indication of higher abnormal returns related to firm size. This paper provides new evidence related to leverage and margin constraints, which is found to not yield any positive risk-adjusted returns for the Norwegian stock market. The standard four-factor model containing the market factor, sizefactor, book-to-market factor, and a momentum factor provides a reasonable fit for the cross-section of Norwegian stock returns.Vi konstruerer fem systematiske risikofaktorer for Oslo Børs i perioden fra 1991 til 2010: en markedsfaktor, og faktorer relatert til selskapsstørrelse, bokverdi av egenkapital dividert på markedsverdien til egenkapital, momentum, og belånings- og finansieringsbegrensninger. Vi finner bevis for en momentumeffekt på kortsiktig avkastning og signifikant positiv avkastning for faktoren tilknyttet bokverdi dividert på markedsverdi. Det er lite som tyder på at det er noen positiv sammenheng mellom estimert beta og påfølgende avkastning, noe som er motstridende til CAPM. Det er ingen indikasjon på høyere abnormal avkastning knyttet til selskapets størrelse. Denne rapporten gir nye bevis knyttet til belånings- og finansieringsbegrensninger for Oslo Børs, som ikke viser seg å gi noen signifikant positiv risikojustert avkastning. En standard firefaktormodell som inneholder markedsfaktoren, størrelsesfaktoren, bok-til-markedsverdifaktoren og en momentumfaktor gir best beskrivelse av det norske aksjemarkedet.Master i okonomi og administrasjo
