La reputación como ventaja competitiva sostenible
2019
En los actuales contextos globalizados, las empresas se encuentran en una búsqueda incesante por diferenciarse. La oferta de bienes y servicios en general ha crecido, tanto en cantidad como en calidad. A tal grado se produce este fenómeno que, si la empresa no encuentra una buena razón (y la comunica correctamente) para ser elegida por los consumidores, se condena a perder mercado y/o rentabilidad. Las tradicionales fuentes de ventaja competitiva se encuentran sobreexplotadas. Además de presentar problemas con su sostenibilidad. En principio, es necesario definir la reputación corporativa y diferenciarla de otros conceptos con los cuales se relaciona. Con esta base, se procederá a referirse…
E-Fairs: a Cyber-Physical System for Aggregation and Economy of Scale in e-Commerce
2018
In recent years, the e-commerce arena has deeply changed because of the advent of new business models and the growing weight of huge global actors like Amazon. Some business models create competition between users, and the product price tends to rise (e.g., online auctions); other models, including group-buying, make users cooperate, and the price tends to go down. The present study extends the group-buying model and proposes a cyber-physical system called e-fair, in which both sellers and buyers are grouped to negotiate on a specific product or service. E-fairs minimize the global purchase price and the shipping resources respectively with the aggregation of demand and supply as well as or…
�ber den Einflu� der Verarbeitung und Konservierung auf Bek�mmlichkeit und N�hrwert der Nahrungsmittel
1951
Des haushaltsubliche Zubereiten der Nahrungsmittel wie Kochen, Braten usw. beeintrachtigt Nahrwert und Ausnutzbarkeit der Nahrung nur unwesentlich, verbessert sie vielmehr haufig sogar. Durch Masnahmen der Konservierung, vor allem Erhitzen unter Druck, kann es aber zu weitgehender Zerstorung von Nahrstoffen oder zu chemischen Verenderungen der Art kommen, das Nahrwert oder Verdaulichkeit wesentlich herabgesetzt werden. Dies wird an Hand von Beispielen in erster Linie bei Vitaminen und Eiweiskorpern gezeigt. Aus diesen Beispielen ergibt sich die grose Bedeutung, die einer schonenden und zweckmasigen Nahrungsmittelkonservierung zukommt. Optimale Methoden fur Zubereitung und Konservierung von …
Parallel Behaviour – Primary Evidence of an Agreement
2013
Abstract The distinction between legitimate oligopoly and cartels is tackled by each competition authority. A parallel behaviour in an oligopolistic market might be seen as an anchor for competition's effectiveness, given that companies are required to respond to the decisions of other competitors, trying to keep a realistic and competitive position to ensure welfare. Cartels offer an opposite perspective of what competition really means. Apart from the observation of the econometrical model presented in the article, the final assessment should consider the particularities of the legal and economic environment, to conclude on the existence of a cartel based on reasonable grounds.
Adoption of ubiquitous crm for operational sustainability of the firms: Moderating role of technology turbulence
2021
Ubiquitous CRM (UCRM) enhances customer relationship management. It can sense customer needs and demands, to which firms can respond quickly. Therefore, UCRM helps to improve a firm’s agility. There is a growing interest among researchers and practitioners to understand how the adoption of UCRM impacts the sustainability of firms’ operations, but not many studies have investigated this issue. In this context, the aim of this study is to examine how firms’ absorptive capacity and dynamic capability could impact the adoption of UCRM to influence the operational sustainability of the firms and their performance. The study also investigates the moderating role of technology turbulence on the re…
Suppression of phase ambiguity in digital holography by using partial coherence or specimen rotation
2008
In this paper we present two approaches for extracting the surface profile as well as obtaining 3D imaging of near field objects by usage of partial coherence and digital holography. In the first approach a light source with given temporal partial coherence is used to illuminate a near field object. The reflected light is interfered with the reference source. By computing the local contrast of the generated fringes one may estimate the 3D topography and the profile of the object. This approach extracts the 3D information from a single image, and its accuracy does not depend on triangulation angle like in fringe projection methods. The second approach is tomography based. There we illuminate…
Rationally designed haptens for highly sensitive monoclonal antibody-based immunoanalysis of fenhexamid.
2018
Immunochemical methods have been consolidated during the last few years as complementary analytical strategies for chemical contaminant and residue determination. However, generation of suitable immunoreagents for small organic molecules demands adequate hapten design. In this study, fenhexamid was considered as a model compound and novel haptens were designed and synthesized in order to evaluate the influence of the linker tethering site on antibody binding properties and immunoassay parameters. Haptens were conceived with the spacer arm at different positions, while the more antigenic aromatic moiety was kept free. The synthesis of these functionalized compounds was accomplished by total …
Generation of anti-azoxystrobin monoclonal antibodies from regioisomeric haptens functionalized at selected sites and development of indirect competi…
2012
Azoxystrobin is a modern strobilurin fungicide used around the world to combat prime diseases affecting highly valuable crops. Accordingly, residues of this chemical are frequently found in food, even though mostly under maximum tolerated levels. We herein describe the development of an indirect competitive immunoassay for the determination of azoxystrobin residues. A panel of monoclonal antibodies displaying subnanomolar affinity to azoxystrobin was generated using, as immunizing haptens in mice, four functionalized derivatives carrying the same spacer arm located at different rationally chosen positions. This collection of antibodies was thoroughly characterized with homologous and hetero…
Synthesis of azoxystrobin transformation products and selection of monoclonal antibodies for immunoassay development
2012
The use of agrochemicals for crop protection may result in the presence of toxic residues in soils and aquatic environments, besides in foodstuffs. Most often just the parent compound is included in the definition of pesticide residue, even though chemicals resulting from biotransformation and degradation routes might also be of toxicological relevance. Azoxystrobin is a broad-spectrum systemic fungicide widely used worldwide to combat pathogenic fungi affecting plants. We herein report the synthesis and detailed chemical characterization of several of the most relevant metabolites and degradates of azoxystrobin. These compounds were further employed as ligands for screening a collection of…
3D reconstruction techniques made easy: know-how and pictures
2005
Three-dimensional reconstructions represent a visual-based tool for illustrating the basis of three-dimensional post-processing such as interpolation, ray-casting, segmentation, percentage classification, gradient calculation, shading and illumination. The knowledge of the optimal scanning and reconstruction parameters facilitates the use of three-dimensional reconstruction techniques in clinical practise. The aim of this article is to explain the principles of multidimensional image processing in a pictorial way and the advantages and limitations of the different possibilities of 3D visualisation.
