How consumers judge brands endorsed by corporations : a process-based explanation

Ibraheem, Khaled Assad January 2012 (has links)
Corporations follow different strategies to leverage their existing brands. One of these is brand extension, which is the extension of an existing brand to a new product category. In this strategy, corporations have two alternatives, one of which is the family brand extension. Here, the new product is introduced under the corporate name along with the extension’s category name (e.g. Sony mobile, Nestlé mineral water, and Gillette shampoo). The second alternative is the brand endorsement. In this alternative, the extension is given a new name. Moreover, the corporation’s name is presented as the endorser in the extension brand structure and communications (e.g. Scandic by Hiliton, Courtyard by Marriott). However, the focus will be on the extension brand name, rather than the corporate name. The endorser’s main role is to provide credibility and substance to the endorsed brand, while maintaining the endorsed brand’s freedom to establish its unique associations and personality. It is well-known that, in the family brand extension, the perceived fit between the parent brand and the extension product category moderates consumers’ judgement of the extension (i.e. the new product which is introduced under the parent name). However, widely-diversified corporations (e.g. Nestlé, Unilever) often endorse their products to leverage their corporate credibility. The proliferation of using a corporate name to endorse products in the case of corporations with diversified product portfolios puts the importance of the fit on the corporate endorser, and the endorsed product brand under scrutiny. Specifically, it raises the following questions: to what extent is the perceived fit between the corporate brand endorser and the endorsed brand really important in an endorsement context? What is the relative importance of fit and endorser credibility in an endorsement context, and why? In the current research, it is proposed that both corporate credibility and fit affect consumers’ judgement in an endorsement context. However, the endorser credibility is more important. It is also proposed that corporate credibility is more important than fit because it is more diagnostic, which makes the endorser credibility more recallable for the consumer. The current research results have shown that, when consumers can easily recall information related to the endorser credibility and the fit between the endorser and the endorsed brand, both endorser credibility and fit has an effect on the endorsed brand. However, endorser credibility has a stronger effect on the endorsed brand judgement than fit. Moreover, the results have shown that fit moderates the effect of corporate credibility only when the endorser credibility is high. When consumers have difficulty recalling information, fit does not moderate the effect of the endorser credibility on the endorsed brand. The current research findings have been obtained by conducting two experiments. In Experiment One, corporate credibility and perceived fit were manipulated in an endorsement context. Consumer judgement of the endorsed brand was measured by the perceived quality and purchase intention. Experiment Two was conducted to study the impact of the information accessibility on the effect of the endorser credibility and fit on the endorsed brand judgement. Endorser credibility, fit and information accessibility were manipulated in an endorsement context. Perceived quality and purchase intention of the endorsed brand were also used to measure the consumers’ judgement of the endorsed brand.

Causes, consequences, and cures of myopic loss aversion - an experimental investigation

Fellner, Gerlinde, Sutter, Matthias January 2008 (has links) (PDF)
We examine in an experiment the causes, consequences and possible cures of myopic loss aversion (MLA) for investment behaviour under risk. We find that both, investment horizons and feedback frequency contribute almost equally to the effects of MLA. Longer investment horizons and less frequent feedback lead to higher investments. However, when given the choice, subjects prefer on average shorter investment horizons and more frequent feedback. Exploiting the status quo bias by setting a long investment horizon or low feedback frequency as a default turns out to be a successful behavioural intervention that increases investment levels.

VALUATION OF RECREATIONAL BEACH QUALITY AND WATER QUALITY MANAGEMENT STRATEGIES IN OAHU

Penn, Jerrod M 01 January 2013 (has links)
Hawaii’s pristine ocean and tropical environment is a keystone of Hawaii tourism and the state economy. Water pollution from stormwater and development threatens the beach quality to both residents and tourists. In order to understand the lost nonmarket value, we assess changes in quality of beach characteristics including water and sand quality, swimming safety conditions, and congestion using a Discrete Choice Experiment of recreational beach users. Further, we study willingness to pay (WTP) for water management strategies in Hawaii using another discrete choice experiment, including structural and nonstructural Best Management Practices, testing, monitoring, and educational efforts. Using a mixed logit model, beach quality results suggest similar preferences among resident and tourists. Both groups consistently have higher WTP to avoid poor quality levels versus obtaining excellent levels. Additionally, water quality is the single most important attribute. For the policy discrete choice experiment, both parties exhibit similar ranking of WTP to initiate water quality management strategies, with improved testing methods followed by education having the highest WTP. Lastly, we use Benefit-Cost analysis to find that all significant management strategies may be viable, since WTP is greater than the predicted cost of implementation based on expert opinion of Hawaiian policy leaders.

A la recherche d'un femtomêtre

Marqués, F.M. 19 January 2012 (has links) (PDF)
Mes recherches au cours des 21 dernières années ont débuté à IFICValencia, puis quelques années au GANIL et de Valencia à nouveau, et enfin au labo depuis 1994. Bien que mon passage à LPC représenté une forte variation thématique, j'ai fait un effort pour trouver un scénario qui suit la plupart des projets que j'ai participé, et ce scénario est la quête pour mesurer les distances nucléaire. Sur cette voie, je vais inclure la couverture des articles que j'ai trouvés significative, leur version complète peut être trouvée à la fin de ce document, dans leur ordre d'apparition.

Parity violating asymmetries in the Gº experiment: Pion photoproduction on the Δ resonance

Coppens, Alexandre Francois Constant 13 September 2010 (has links)
Symmetry tests and more precisely parity violation experiments using the properties of the weak interaction give us unique insight into the internal hadronic structure of matter. The Gº experiment at Jefferson Laboratory used parity violating electron scattering to probe the strange quark contribution to the electromagnetic nucleon form factors, (GMs and GEs) as well as the axial contribution, (GAe). The data taken during the experiment provide further information on the axial transition form factor of the N - $\Delta$ transition, (GANΔ), as well as the scale of the low energy constant (dΔ) characterizing the parity violating γNΔ coupling. The analysis of backward angle Gº data taken with a liquid deuterium target to deduce the parity violating asymmetry for pion photoproduction on the Δ resonance, and the first experimental constraint on the value of dΔ, are reported in this thesis. The results showed that dΔ = (8.3 ± 25.3) gπ where the uncertainty is dominated by statistics, and that 75 percent of the theory range would be excluded by this measurement at 1 sigma.

Etude des interactions entre enzymes immobilisées et inhibiteurs au moyen des radiotraceurs. Application à la réalisation d'électrodes enzymatiques pour le dosage des composés toxiques

Guyonnet, René 05 December 1978 (has links) (PDF)
La connaissance des poisons est fort ancienne. Si les premières intoxications observées ont eu pour origine la consommation, par ignorance ou par méprise de végétaux vénéneux, il semble que les premiers toxiques utilisés aient servi à empoisonner des flèches destinées à la chasse ou à la guerre. Le terme de toxique dérive d'ailleurs du mot grec "toxon" qui signifie "arc". L'utilisation durant la première Guerre Mondiale du fameux "gaz moutarde", jusqu'aux "Nerve Gases" et aux défoliants confirment que l'humanité s'est toujours préoccupée de trouver des moyens de tuer. De l'exécution de Socrate à la ciguë, à la Reine Catherine de Médicis qui fabriquait elle-même ses poisons dans son cabinet secret de Blois, on peut dire que la toxicologie classique a conduit aux premières études des inhibiteurs enzymatiques. La cinétique d'inhibition produite par une substance se liant réversiblement avec une enzyme fut développée dans une publication originale de MICHAELIS et MENTEN en 1913, mais il fallut attendre un certain nombre d'années avant que ce type d'inhibition fut caractérisé. L'isolement et la purification partielle de la première enzyme l'Uréase en 1926 par SUMMER fut l'étape déterminante pour la suite, car les études de l'inhibition de l'enzyme en solution devenaient alors possible. En 1930 alors que COOK démontrait expérimentalement le mécanisme de l'inhibition compétitive énoncée 17 ans plus tôt par MICHAELIS et MENTEN, à la même époque HALDANE établissait un autre type d'inhibition qu'il nommait "non compétitif ". Depuis SUMMER les études portant sur l'inhibition de l'enzyme en solution ou de suspension de cellules sont considérables et de grands noms restent attachés (WILSON, ALDRIDGE, NACHMANSON, MONOD), C'est sur ces travaux fondamentaux que reposent encore aujourd'hui les bases de l'enzymologie classique.

Development of a Wind Turbine Test Rig and Rotor for Trailing Edge Flap Investigation

Abdelrahman, Ahmed 13 September 2014 (has links)
Alleviating loads on a wind turbine blades would allow a reduction in weight, and potentially increase the size and lifespan of rotors. Trailing edge flaps are one technology proposed for changing the aerodynamic characteristics of a blade in order to limit the transformation of freestream wind fluctuations into load fluctuations within the blade structure. An instrumented wind turbine test rig and rotor were developed to enable a wide-range of experimental set-ups for such investigations. The capability of the developed system was demonstrated through a study of the effect of stationary trailing edge flaps on blade load and performance. The investigation focused on measuring the changes in flapwise bending moment and power production for various trailing edge flap parameters. The blade was designed to allow accurate instrumentation and customizable settings, with a design point within the range of wind velocities in a large open jet test facility. The wind facility was an open circuit wind tunnel with a maximum velocity of 11m/s in the test area. The load changes within the blade structure for different wind speeds were measured using strain gauges as a function of flap length, location and deflection angle. The blade was based on the S833 airfoil and is 1.7 meters long, had a constant 178mm chord and a 6o pitch. The aerodynamic parts were 3D printed using plastic PC-ABS material. The total loading on the blade showed higher reduction when the flap was placed further away from the hub and when the flap angle (pitching towards suction side) was higher. The relationship between the load reduction and deflection angle was roughly linear as expected from theory. The effect on moment was greater than power production with a reduction in moment up to 30% for the maximum deflection angle compared to 6.5% reduction in power for the same angle. Overall, the experimental setup proved to be effective in measuring small changes in flapwise bending moment within the wind turbine blade.
