Competitive advantage in a global market: The Case of the Norwegian Salmon Farming Industry A comparative study of the Chilean salmon farming industry
2018
Master's thesis Business Administration BE501 - University of Agder 2018 Purpose – This study tries to address the differentiation done by a mature industry as a comparative study to Felzensztein and Gimmon´s (2014) paper on the Chilean farmed salmon industry. It focuses on how firms might improve their performance in an international context. Choosing between either cost-advantage or differentiation as a form gaining a competitive advantage, this study further addresses the usage of the country of origin effect as a form of differentiation. Design/Methodology/Approach – The research unit of the thesis is set in the Norwegian salmon farming industry, alas the biggest producer of salmon in t…
Methylation status of VTRNA2-1/nc886 is stable across populations, monozygotic twin pairs and in majority of tissues.
2022
Aims & methods: The aim of this study was to characterize the methylation level of a polymorphically imprinted gene, VTRNA2-1/nc886, in human populations and somatic tissues.48 datasets, consisting of more than 30 tissues and >30,000 individuals, were used. Results: nc886 methylation status is associated with twin status and ethnic background, but the variation between populations is limited. Monozygotic twin pairs present concordant methylation, whereas similar to 30% of dizygotic twin pairs present discordant methylation in the nc886 locus. The methylation levels of nc886 are uniform across somatic tissues, except in cerebellum and skeletal muscle. Conclusion: The nc886 imprint may be est…
Breaking Stereotypes Concerning Remigrated Children - A Multinational Possible Intervention Plan through School
2021
The article is based on a multinational study involving five countries (Romania, Portugal, Italy, North Macedonia, and Iceland) facing the return migration or remigration situation. Pupils (n = 1615), teachers (n = 370), future teachers (n = 166) and youth workers (n = 30) were questioned about various aspects regarding the subject. Among the matters, cultural needs appear to the most important. Based on the statistical analysis, the article describes the dynamics of the dependent variables, with highlighted interest on cultural needs. Psychological and social needs, cultural needs, and educational needs are discussed and link conclusions appear. Following the analysis, an intervention plan…
Veterinary drug residues in meat: Concerns and rapid methods for detection.
2007
The use of substances having hormonal or thyreostatic action as well as β-agonists is banned in the European Union. However, sometimes forbidden drugs may be added to feeds for illegal administration to farm animals for promoting increased muscle development or increased water retention and thus obtain an economical benefit. The result is a fraudulent overweight of meat but, what is worse, residues of these substances may remain in meat and may pose a real threat to the consumer either through exposure to the residues, transfer of antibiotic resistance or allergy risk. This has exerted a great concern among European consumers. The control of the absence of these forbidden substances in anim…
Distribution of YLOID in soil-grapevine system (Vitis vinifera L.) as tool for geographical characterization of agro-food products. A two years case …
2017
The knowledge of a chemistry relationship between the soil and the agricultural products is an important tool for the quality assessment of food. We studied YLOID (Y, La and lanthanoids), recognized as very useful tracers due their coherent and predictable behavior, to trace and evaluate their distribution from soil to the grape in Vitis vinifera L. Because much of the world’s viticulture is based on grafting, and rootstocks have proved affect vine growth, yield, fruit and wine quality, we carried out experimental trials to analyse the YLOID distribution of two different red cultivars, grafted onto six different rootstocks, on the same soil. The YLOID amounts, the relationship Heavy vs Ligh…
Exemplarity measurement and estimation of the level of interjudge agreement for two categories of French red wines
2015
Abstract Exemplarity measurements of wines by at least 20 judges are used to estimate the degree of interjudge (dis)agreement and to tell wines apart into two contrasting extremes. Two sets of French red wines – Pinot noir from Burgundy and Cabernet franc from the Loire Valley – are studied separately but by the same approach. Short-listing criteria are used to collate 40 starting-price and middle-range wines for each set differing a priori in olfactory terms. Wine professionals assess their local wines first orthonasally and then, independently, by global evaluation. A pool of descriptive and inferential statistics indicates there is generally neither complete divergence nor real agreement…
Evaluation of French and New Zealand Sauvignon wines by experienced French wine assessors
2010
International audience; Certain odours are commonly associated with the bouquet of Sauvignon blanc wine. These characteristic varietal odours can vary to reflect origin of a Sauvignon blanc wine. In the present study, Sauvignon blanc wines from sub-regions of Marlborough, New Zealand, and from north France (Sancerre, Loire, and Saint Bris) were investigated in terms of (i) distinctiveness of country of origin, (ii) odour profile, and (iii) the concept of typicality (Ballester, J., Dacremont, C., Le Fur, Y., & Etievant, P. (2005). The role of olfaction in the elaboration and use of the Chardonnay wine concept. Food Quality and Preference, 16, 351-359). Twenty-three experienced French wine ta…
Evolution of anthocyanin profile from grape to wine
2010
<p style="text-align: justify;"><strong>Aims</strong>: This study aimed at acquiring knowledge of the evolution of anthocyanins from grape to wine and the possibility of deducing the varietal origin of a wine from its anthocyanin profile.</p><p style="text-align: justify;"><strong>Methods and results</strong>: The anthocyanin « fingerprint », or profile, of a series of autochthonous Sicilian accessions and their respective young wines was determined by HPLC-DAD in 2008. Data were evaluated by taking into account the evolution of the percentages of side-ring dioxygenated and tri-oxygenated anthocyanins, the ratio between acetylated and p-coumaroylate…
Sensory and chemical characterisation of Sauvignon blanc wine: Influence of source of origin
2011
Abstract The main objective of the study was to investigate influence of geographical location on volatile composition and perceived flavour profile of Sauvignon wines of New Zealand (Marlborough), French (Sancerre; Loire; Saint Bris), and Austrian (Styria) origin. Nineteen New Zealand wine professionals evaluated 18 Sauvignon wines, 6 from each source of origin, by sensory methods that included intensity ratings to experimenter-provided descriptors, typicality ratings, and classification tasks (non-directed and directed sorting). Results demonstrated that wines from the three sources of origin were separated by sensory analyses, with New Zealand wines dominated by perceived green character…
Exploring minerality of Burgundy Chardonnay wines: a sensory approach with wine experts and trained panellists
2013
Background and Aims The use of minerality as a wine descriptor has increased in the last few years. Minerality always suggests high quality and evokes a link between wine and the soil. The sensory meaning of minerality, however, is not yet clearly understood. The present study was designed to understand how wine experts conceptualise minerality and to explore whether they can judge wine minerality in a consensual way. Methods and Results Experts carried out an orthonasal free sorting task on 16 Chardonnay wines. Afterwards, they rated their mineral character according to two conditions: orthonasally and on the palate while wearing a nose-clip. The experts also answered a questionnaire in wh…
