Detection and discrimination of organophosphorus pesticides in water by using a colorimetric probe array
2014
[EN] Detection and discrimination of several organophosphorus pesticides in water using a colorimetric probe array containing twelve dyes has been achieved. A clear discrimination for malathion, leptophos, dichlorvos, dibrom and diazinon was observed. The array was used to determine the concentration of diazinon in orange leaves
Millenials’ intentions to book on Airbnb
2018
The sharing economy has witnessed a significant growth in recent years, enhanced by the development of online platforms. In particular, Airbnb has witnessed a significant worldwide year-on-year growth. Given the importance and popularity of Airbnb, it is crucial to examine which factors affect intentions to book on this website. This study proposes and tests a model based on the Theory of Reasoned Action, to examine millennials’ determinants of intentions to book on Airbnb. Based on two online surveys targeting millennials from Germany and China, the results show that intentions to book on Airbnb is mostly influenced by subjective norm, desire for unique accommodation and variety, attitude …
Influencia de la percepción multisensorial en la experiencia, satisfacción y felicidad del consumidor de música en vivo. Efecto moderador de la disca…
2023
La presente tesis doctoral se centra, a lo largo de cinco capítulos, en analizar la relación de la percepción multisensorial y la experiencia del consumidor en el contexto de la música en vivo. Además, estudia el efecto de esta última en la satisfacción, la felicidad subjetiva y la intención de compra, para personas con y sin discapacidad. El primer capítulo describe, por una parte, el contexto de la música y, por otra, aborda cuestiones relativas a la discapacidad de los consumidores. En el segundo capítulo se afronta la revisión de la literatura sobre: percepción multisensorial y experiencia de consumo. El tercer capítulo presenta en primera instancia el objetivo general y los objetivos e…
Environmental values in industrial marketing relationships
2017
Concern for the natural environment has become an issue that virtually all companies have to address. Literature suggests that an environmentally oriented marketing strategy, such as an environmental brand image, yields competitive advantage for the supplier in the form of improved customer outcomes and financial performance. At the same time, key barriers to environmental purchasing are found to be related to higher perceived cost and lack of environmental interest among purchasing professionals. In addition, research has repeatedly revealed a gap between customers’ environmental values and attitudes and their manifestation in purchasing behavior. This dissertation contributes to the inter…

Aim The absence of reliable single serum biomarkers for oral premalignant lesion (OPL) and oral squamous cell carcinoma (OSCC) limits early diagnosis, monitoring of advanced disease, and prediction of prognosis. Methods In this prospective study, serum levels of matrix metalloproteinase (MMP)-2, MMP-3, MMP-13, insulin-like growth factor (IGF)-1, and IGF-binding protein (IGFBP)-3 were measured in 81 untreated OSCC patients, 49 healthy subjects, and 75 individuals with OPLs, and correlated with clinicopathological parameters. Results Serum levels of MMP-3 were significantly higher in OSCC patients compared to healthy subjects (p=0.004). Mean IGF-1 and IGFBP-3 levels in OSCC patients were sign…
Mobile CRM in industrial firms : salespeople's intention to adopt mobile solutions
2013
Mobiiliteknologian ja -sovellusten vaikutus organisaatioiden suorituskykyyn on herättänyt huomiota sekä organisaatioissa että akateemisessa maailmassa. Ei kuitenkaan vielä tarpeeksi tiedetä siitä, mikä saa myyntihenkilöstön omaksumaan mobiiliteknologiaa. Tämä tutkimus osallistuu tähän keskusteluun tutkimalla, mitkä tekijät vaikuttavat myyntipäälliköiden aikomuksiin käyttää mobiilia asiakkuuksienhallintajärjestelmää. Tämän tutkimiseksi, käsitteellinen malli rakennettiin teknologian hyväksymiseen ja omaksumiseen liittyvän kirjallisuuden pohjalta. Erityistä näkemystä haettiin mobiiliteknologian omaksumista ja myyntiä tukevia teknologioita käsittelevästä kirjallisuudesta. Tutkimus hyödynsi koke…
Optimal Spectral Wavelengths for Discriminating Orchard Species Using Multivariate Statistical Techniques
2019
Sustainable management of orchard fields requires detailed information about the tree types, which is a main component of precision agriculture programs. To this end, hyperspectral imagery can play a major role in orchard tree species mapping. Efficient use of hyperspectral data in combination with field measurements requires the development of optimized band selection strategies to separate tree species. In this study, field spectroscopy (350 to 2500 nm) was performed through scanning 165 spectral leaf samples of dominant orchard tree species (almond, walnut, and grape) in Chaharmahal va Bakhtiyari province, Iran. Two multivariable methods were employed to identify the optimum wavelengths:…
Structural Parameters under Partial Least Squares and Covariance-Based Structural Equation Modeling : A Comment on Yuan and Deng (2021)
2023
In their article, Yuan and Deng argue that a structural parameter under partial least squares structural equation modeling (PLS-SEM) is zero if and only if the same structural parameter is zero under covariance-based structural equation modeling (CB-SEM). Yuan and Deng then conclude that statistical tests on individual structural parameters assessing the null hypothesis of no effect can achieve the same purpose in CB-SEM and PLS-SEM. Our response to their article highlights that the relationship they find between PLS-SEM and CB-SEM structural parameters is not universally valid, and that consequently, tests on individual parameters in CB-SEM and PLS-SEM generally do not fulfill the same pur…
Detección de nuevos marcadores asociados a daño por reperfusión y fibrosis en infarto de miocardio validados histopatológicamente mediante análisis m…
2022
La resonancia magnética cardiovascular (RMC) con realce tardío es la técnica de referencia para la evaluación no invasiva del daño cardíaco después de un infarto de miocardio (IM). Sin embargo, la interpretación de estas imágenes en términos de daño tisular es aún complicado y el uso de agentes de contraste en esta técnica está contraindicado en un amplio sector de la población con insuficiencia renal crónica. La microscopía de resonancia magnética (MRM) proporciona un nivel de detalle comparable al objetivo macroscópico de la microscopía óptica. Por ello, podría ser una herramienta muy útil en la interpretación de la imagen de RMC y en la identificación de nuevos marcadores de imagen de re…
Satisfaction résidentielle et métriques paysagères : étude des relations statistiques par la méthode PLS
2011
National audience; La satisfaction résidentielle constitue une composante importante de la satisfaction globale des individus et participe de façon non-négligeable à leur bien-être et à leur bonne qualité de vie(Barresi et al., 1984). À ce titre, il semble que cette question occupe une place de plus en plus importante dans les réflexions portant sur le futur des villes. Dans un contexte de développement durable, la qualité de vie constitue en effet un enjeu majeur au même titre que la nécessité de réduire les externalités néfastes sur l'environnement ou la consommation énergétique. Alors que les retombées environnementales ou la consommation énergétique peuvent, en règle générale, être plus…
