    Get PDF
    En los últimos años, las empresas y los académicos son cada vez más conscientes de los beneficios que se derivan de la creación y entrega de valor a los clientes. Sin embargo, la investigación empírica desarrollada sobre el valor de un servicio es todavía escasa. Este articulo se orienta hacia esta cuestión, centrándose en la medida del valor percibido en el ámbito del consumidor de servicios (telefonía móvil) y desde una perspectiva relacional. Después de una revisión de la literatura relevante sobre el concepto de valor percibido, proponemos dos instrumentos alternativos de medida del mismo y utilizamos la estrategia de modelos estructurales competitivos para comparar y apreciar la validez y fiabilidad de los modelos alternativos propuestos

    Son numerosas las investigaciones que han analizado la cadena de lealtad como instrumento que profundiza en el comportamiento futuro del cliente y en las interrelaciones entre sus variables intermedias: la calidad de servicio percibida y el grado de satisfacción del cliente. Tomando como referencia estos estudios, en esta investigación se persiguen tres objetivos concretos: en primer lugar, analizar la influencia indirecta que tiene la imagen percibida por el cliente sobre esa cadena de lealtad; en segundo lugar, estudiar la heterogeneidad del mercado en función de las características personales de los individuos, realizando una segmentación ‘a priori’ a través de la ‘necesidad de variedad’ o ‘nivel óptimo de estimulo’; en tercer lugar, analizar el comportamiento dispar del modelo propuesto en función de los cluster alcanzados. Para la contrastación de las hipótesis se realiza un estudio empírico en el sector turístico. Las conclusiones ponen de manifiesto que la influencia de la imagen sobre la cadena de lealtad está condicionada a la heterogeneidad del mercado.There is plenty of evidence analyzing the loyalty chain as a valid instrument to study customer’s future behaviour. Building on this framework, authors pursue three research objectives: first, to study the indirect influence of perceived image on this loyalty chain; secondly, to explore the effect of market heterogeneity according to customer’s personal characteristics, conducting an “a priori” segmentation through “variety seeking” or “optimum level of stimulus”; finally, we analyze how these clusters account for the significant differences in the model. An empirical study is conducted within the tourism industry in order to test the hypotheses. Results evidence that image has a strong influence on the loyalty chain, although this influence is partially conditioned by market heterogeneity

    [Resumen] Con nuestro estudio pretendemos encontrar relaciones entre la inteligencia emocional y el rendimiento académico con una muestra de 344 alumnos de entre 14 y 16 años de edad (1º y 2º ESO). Hemos utilizado para evaluar la inteli- gencia emocional medidas de autoinforme, concretamente el TMMS-24 (Trait Meta Mood Scale) y para el rendimiento académico hemos utilizado no sólo medidas globales como la nota media y el número de suspensos, también la calificación en cada una de las materias básicas de la ESO: Matemáticas, Lengua, Inglés, Ciencias Sociales y Ciencias Naturales. Por último, debido a que existen diferencias en inte- ligencia emocional asociadas al género, supo- nemos que las correlaciones entre el rendimien- to escolar e inteligencia emocional serán dife- rentes entre chicos y chicas.[Abstract] Our study aims to find relationships bet- ween emotional intelligence and academic performance with a sample of 344 students between 14 and 16 years of age (1st and 2nd ESO). We used self-report measures to assess emotional intelligence, namely TMMS-24 (Trait Meta Mood Scale) and for the academic performance measures we have used not only the global average and the number of failures, but the grades in each of the core subjects of the ESO: Mathematics, Language, English, Social Sciences and Natural Sciences. Finally, due to differences in emotional intelligence related to gender, we assume that the correla- tions between school performance and emo- tional intelligence are different between boys and girls

    Creating customer value through service experiences: an empirical study in the hotel industry

    Get PDF
    The main research objectives of this paper are: first, to identify the three levels of a service evaluation: attributes (service value), outcome (service experience), and values (developing service relationships); secondly, to differ and to relate the perceptions of service value with service experience components. According to the ‘theory of cognitive schemata’ and the ‘means-end theory’, the components of a service experience are hierarchical in nature. Thus, customers evaluate their experiences – and build their service relationships – taking into account not only the attributes of the service (first level of abstraction), but also the outcomes and consequences that those attributes cause on them (highest level of abstraction). Marketing research has been mostly focused on the detection of affective aspects of quality and satisfaction. However, little attention has been devoted to the cognitive organization of the structure of evaluative judgments in the customer’s mind. According to our results, servicescape provides the strongest driver of service value when creating service experiences, followed by service equity. Elements such as the service atmosphere, hotel facilities, etc. are significant contributors to customer’s easiness to relax and escape from routine, which are the two major factors in the service experience. Similarly, hotel managers should take note of the importance of service equity by developing strong brand images which capitalize on customer’s experiences rather than service attributes

    Co-occurrence of viral and bacterial pathogens in disease outbreaks affecting newly cultured sparid fish

    Several microbial disease outbreaks in farm stocks of newly cultured sparid fish species, such as common seabream, redbanded seabream, and white seabream, were recorded from 2004 to 2006. This study describes the isolation and characterization of the potential causative agents, either bacteria or viruses, of these outbreaks. The isolated bacterial strains were characterized according to traditional taxonomical analyses and sequencing of a 16S rDNA fragment. Most bacteria were identified as Vibrio spp. and Photobacterium damselae subsp. damselae. The development of cytopathic effects (CPE) on different fish cell lines, the application of specific nested-PCR tests for infectious pancreatic necrosis virus (IPNV), viral nervous necrosis virus (VNNV) and viral hemorrhagic septicemia virus (VHSV), and subsequent sequence analyses were used for virus detection and identification. VNNV, related to the striped jack neural necrosis virus (SJNNV) genotype, and VHSV, related to the genotype Ia, were the only viruses detected. VNNV was isolated from the three fish species under study in five different outbreaks, whereas VHSV was isolated from common seabream and white seabream during two of these outbreaks. IPNV was not detected in any case. [Int Microbiol 2007; 10(3):193-199

    Cigarette smoking is associated with increased risk for all histologic types of lung cancer, but why the strength of this association is stronger for squamous cell carcinoma than adenocarcinoma of the lung (SQC-L, ADC-L) is not fully understood. Because nicotine and tobacco-specific nitrosamines contribute to carcinogenesis by activating nicotinic acetylcholine receptors (nAChRs) on lung tumors and epithelial cells, we investigated whether differential expression of nAChR subtypes in these tumors could explain their different association with smoking. Expression of nAChR subunit genes in paired tumor and non-tumor lung specimens from 40 SQC-L and 38 ADC-L patients was analyzed by quantitative PCR. Compared to normal lung, both tumors share: i) transcriptional dysregulation of CHRNA3/CHRNA5/CHRNB4 (α3, α5, β4 subunits) at the chromosomal locus that predisposes to lung cancer; and ii) decreased expression of CHRFAM7A (dupα7 subunit); this last subunit negatively modulates α7-nAChR activity in oocytes. In contrast, CHRNA7 (α7 subunit) expression was increased in SQC-L, particularly in smokers and non-survivors, while CHRNA4 (α4 subunit) expression was decreased in ADC-L. Thus, over-representation of cancer-stimulating α7-nAChR in SQC-L, also potentiated by smoking, and underrepresentation of cancer-inhibiting α4β2-nAChR in ADC-L could explain the different tobacco influences on the tumorigenic process in each cancer typeThis study was supported by grants to C.
