Impact of Product-harm Crisis on Brand Equity: the Moderating Role of Corporate Social Performance

There is an increasing amount of product-harm crisis in the past few years; and the impact of a product-harm crisis becomes more and more influential due to the high increasing speed of globalization. And it is believed that the negative damages to a firm leading to a loss of the intangible assets is bigger than other costs such as the cost of the product recall. Brand equity is a very important and valuable intangible asset for a firm; and it is particularly vulnerable during the crisis. And CSP (CSP) is a hot concept associated with product-harm crisis and brand equity. The aim of this study is to understand how product-harm crisis influences by simultaneously involving CSP as a moderator in a consumer-based level. An experimental study was conducted through an online questionnaire among 198 students in Finland. The questionnaire mainly assessed the consumers’ attitudes towards CSP and brand before/after a fictional product-harm crisis. The results shows that the brand equity was negatively related to the product-harm crisis. And the extent level of crisis’s severity was positively related to the loss of the brand equity; whereas, acknowledged blame was more useful to compensate the loss of brand equity in the low-severity crisis. CSP acted as a moderator role which could compensate the loss of brand equity caused by the product-harm crisis. Managerial implications are also offered for crisis managers, brand managers, and CSR managers.

Fostering product innovation by learning through exporting in Eastern Europe

This study discusses the importance of learning through the process of exporting, and more specifically how such a process can enhance the product innovativeness of a company. The purpose of this study is to investigate the appropriate sources of learning and to suggest an interactive framework for how new knowledge from exporting markets can materialize itself into product innovation. The theoretical background of the study was constructed from academic literature, which is related to concepts of learning by exporting, along with sources for learning in the market and new product development. The empirical research in the form of a qualitative case study was based on four semi-structured interviews and secondary data from the case company official site. The interview data was collected between March and April 2015 from case company employees who directly work in the department of exporting and product development. The method of thematic analysis was used to categorize and interpret the collected data. What was conclusively discovered, was that the knowledge from an exporting market can be an incentive for product innovation, especially an incremental one. Foreign customers and competitors as important sources for new knowledge contribute to the innovative process. Foreign market competitors’ influence on product improvements was high only when the competitor was a market leader or held a colossal market share, while the customers’ influence is always high. Therefore, involving a foreign customer in the development of a new product is vital to a company that is interested in benefiting from what is learned through exporting. The interactive framework, which is based on the theoretical background and findings of the study, suggests that exporting companies can raise their product innovativeness by utilizing newly gained knowledge from exporting markets. Except for input, in the form of sources of learning, and product innovation as an output, the framework contains a process of knowledge transfer, the absorptive capacity of a firm and a new product development process. In addition, the framework and the findings enhance the understanding of the disputed relationship between an exporting experience and product innovation. However, future research is needed in order to fully understand all the elements of the framework, such as the absorptive capacity of a firm as well as more case companies to be processed in order to increase the generalization of the framework

Development of a New Welding Product Quality Control and Management System Model for China

The Chinese welding industry is growing every year due to rapid development of the Chinese economy. Increasingly, companies around the world are looking to use Chinese enterprises as their cooperation partners. However, the Chinese welding industry also has its weaknesses, such as relatively low quality and weak management. A modern, advanced welding management system appropriate for local socio-economic conditions is required to enable Chinese enterprises to enhance further their business development. The thesis researches the design and implementation of a new welding quality management system for China. This new system is called ‗welding production quality control management model in China‘ (WQMC). Constructed on the basis of analysis of a survey and in-company interviews, the welding management system comprises the following different elements and perspectives: a ‗Localized congenital existing problem resolution strategies‘ (LCEPRS) database, a ‗human factor designed training system‘ (HFDT) training strategy, the theory of modular design, ISO 3834 requirements, total welding management (TWM), and lean manufacturing (LEAN) theory. The methods used in the research are literature review, questionnaires, interviews, and the author‘s model design experiences and observations, i.e. the approach is primarily qualitative and phenomenological. The thesis describes the design and implementation of a HFDT strategy in Chinese welding companies. Such training is an effective way to increase employees‘ awareness of quality and issues associated with quality assurance. The study identified widely existing problems in the Chinese welding industry and constructed a LCEPRS database that can be used in efforts to mitigate and avoid common problems. The work uses the theory of modular design, TWM and LEAN as tools for the implementation of the WQMC system.

Kinetic and product studies for the oxidtion of organic sulfides and sulfoxides in the presence of transition metal complexes

Rates and products of the oxidation of diphenyl sulfide, phenyl methyl sulfide, p-chlorophenyl methyl sulfide and diphenyl sulfoxide have been determined. Oxidants included t-Bu02H alone, t-Bu02H plus molybdenum or vanadium catalysts and the molybdenum peroxo complex Mo0(02)2*HMPT. Reactions were chiefly carried out in ethanol at temperatures ranging from 20° to 65°C. Oxidation of diphenyl sulfide by t-Bu02H in absolute ethanol at 65°C followed second-order kinetics with k2 = 5.61 x 10 G M~1s"1, and yielded only diphenyl sulfoxide. The Mo(C0)g-catalyzed reaction gave both the sulfoxide and the sulfone with consecutive third-order kinetics. Rate = k3[Mo][t-Bu02H][Ph2S] + k^[Mo][t-Bu02H][Ph2S0], where log k3 = 12.62 - 18500/RT, and log k^ = 10.73 - 17400/RT. In the absence of diphenyl sulfide, diphenyl sulfoxide did not react with t-Bu02H plus molybdenum catalysts, but was oxidized by t-Bu02H-V0(acac)2. The uncatalyzed oxidation of phenyl methyl sulfide by t-Bu02H in absolute ethanol at 65°C gave a second-order rate constant, k = 3.48 x 10~"5 M^s""1. With added Mo(C0)g, the product was mainly phenyl methyl sulfoxide; Rate = k3[Mo][t-Bu02H][PhSCH3] where log k3 = 22.0 - 44500/RT. Both diphenyl sulfide and diphenyl sulfoxide react readily with the molybdenum peroxy complex, Mo0(02)2'HMPT in absolute ethanol at 35°C, yielding diphenyl sulfone. The observed features are mainly in agreement with the literature on metal ion-catalyzed oxidations of organic compounds by hydroperoxides. These indicate the formation of an active catalyst and the complexation of t-Bu02H with the catalyst. However, the relatively large difference between the activation energies for diphenyl sulfide and phenyl methyl sulfide, and the non-reactivity of diphenyl sulfoxide suggest the involvement of sulfide in the production of an active species.

Product Filters, Acyclicity and Suzumura Consistency

In a seminal contribution, Hansson (1976) demonstrates that the collection of decisive coalitions associated with an Arrovian social welfare function forms an ultrafilter. He goes on to show that if transitivity is weakened to quasi-transitivity as the coherence property imposed on a social relation, the set of decisive coalitions is a filter. We examine the notion of decisiveness with acyclical or Suzumura consistent social preferences and without assuming that the social relation is complete. This leads to a new set-theoretic concept applied to product spaces.

The relationship between product design and business models in the context of sustainability

Dans les sphères du développement durable, des modèles d’affaires et du design de produit, certains leviers rendent le croisement de ces trois sphères de plus en plus pertinent. Au croisement de ces trois sphères se trouve une opportunité de comprendre les relations existantes entre le design de produit et les modèles d’affaires afin d’aider les décideurs à développer des solutions davantage durables. L’approche méthodologique de cette recherche utilise un système complexe et est basée sur un paradigme pragmatique. En vue de répondre à la question « Dans quelle mesure des modèles d’affaires et le design de produit sont liés dans un contexte de développement durable? », cette recherche a soigneusement analysé trois cas: Better Place, une compagnie californienne ayant développé une infrastructure permettant le chargement des voitures électriques; Interface Inc., un manufacturier mondial de tuiles de tapis commerciales établi à Atlanta; et Métacycle, un concept d’entreprise développé par une équipe de chercheurs en design à Montréal. Chaque cas a été analysé en corrélant des aspects du design de produit à des éléments de leur modèle d’affaires. Les résultats montrent que dans le contexte du développement durable, le design de produit et les modèles d’affaires sont interdépendants. Les résultats peuvent être résumés en six points: il existe des relations applicables universellement; les innovations de design substantielles jouent un rôle important dans le développement durable; la « durabilité » peut être une qualité émergente d’un modèle d’affaires; les partenariats peuvent être vitaux pour l’intégration des systèmes; un modèle de services a des bénéfices et des limitations considérables; le design peut agir comme levier à l’utilisation d’énergies renouvelables. Pratiquer simultanément l’innovation du modèle d’affaires et du produit peut apporter une valeur ajoutée, susciter des opportunités et augmenter l’efficience sur plusieurs facettes. Toutefois, les risques et les coûts de tels procédés sont souvent très élevés. En aidant à comprendre et définir comment les trois sphères mentionnées plus tôt sont interdépendantes, cette recherche pourrait idéalement inspirer des recherches supplémentaires sur le sujet. L’application par des organisations de la méthodologie et des apprentissages résultant de cette recherche peut permettre à d’autres d’utiliser le croisement entre l’innovation de produit et l’innovation du modèle d’affaires afin de résoudre des enjeux sociaux et environnementaux complexes.

Detection and quantification of staphylococcus aureus enterotoxin B in food product using isotopic dilution techniques and mass spectrometry

L’entérotoxine B staphylococcique (SEB) est une toxine entérique hautement résistante à la chaleur et est responsable de plus de 50 % des cas d’intoxication d’origine alimentaire par une entérotoxine. L’objectif principal de ce projet de maîtrise est de développer et valider une méthode basée sur des nouvelles stratégies analytiques permettant la détection et la quantification de SEB dans les matrices alimentaires. Une carte de peptides tryptiques a été produite et 3 peptides tryptiques spécifiques ont été sélectionnés pour servir de peptides témoins à partir des 9 fragments protéolytiques identifiés (couverture de 35 % de la séquence). L’anhydride acétique et la forme deutérée furent utilisés afin de synthétiser des peptides standards marqués avec un isotope léger et lourd. La combinaison de mélanges des deux isotopes à des concentrations molaires différentes fut utilisée afin d’établir la linéarité et les résultats ont démontré que les mesures faites par dilution isotopique combinée au CL-SM/SM respectaient les critères généralement reconnus d’épreuves biologiques avec des valeurs de pente près de 1, des valeurs de R2 supérieure à 0,98 et des coefficients de variation (CV%) inférieurs à 8 %. La précision et l’exactitude de la méthode ont été évaluées à l’aide d’échantillons d’homogénat de viande de poulet dans lesquels SEB a été introduite. SEB a été enrichie à 0,2, 1 et 2 pmol/g. Les résultats analytiques révèlent que la méthode procure une plage d’exactitude de 84,9 à 91,1 %. Dans l’ensemble, les résultats présentés dans ce mémoire démontrent que les méthodes protéomiques peuvent être utilisées efficacement pour détecter et quantifier SEB dans les matrices alimentaires. Mots clés : spectrométrie de masse; marquage isotopique; protéomique quantitative; entérotoxines

Studies on Thermoplastic Elastomer Based on Linear Low-Density Polyethylene and Latex Product Waste Modified with Thiocarbanilide

Latex waste like glove waste was effectively modified using a new reclaiming agent, thiocarbanilide. This modified waste was blended with linear low-density polyethylene (LLDPE) to develop a novel thermoplastic elastomer. Both uncrosslinked and dynamically crosslinked blends were prepared and their properties were studied. The results were found to be comparable to those of conventional thermoplastic elastomers.

Studies on the Rheology and the Mechanical Properties of Thermoplastic Elastomer from Latex Product Waste and High Density Polyethylene

Latex waste products contain rubber hydrocarbon of very high quality, which is only lightly cross linked. Selected wastes such as thread waste and glove waste were modified into processable materials by a novel economic process and thermoplastic elastomers were prepared by blending these modified waste materials with high density polyethylene in various proportions. The mechanical properties as well as the rheological behaviour of these blends were evaluated and compared with those of the natural rubber-high density polyethylene blends.
