Antecedentes y efectos del burnout-engagement del vendedor
2012
ResumenEl burnout o «síndrome del trabajador quemado» ha demostrado tener una gran importancia en el campo de las ventas. Sin embargo, no se han encontrado estudios que analicen en profundidad su opuesto, el engagement. El presente trabajo trata de profundizar en los antecedentes y efectos de un concepto integrador de ambos opuestos denominado burnout-engagement. Para ello, se realiza un estudio sobre 107 vendedores de distintos sectores. Los datos obtenidos, dado el tamaño de la muestra, son analizados mediante el sistema PLS. En lo relativo a antecedentes, los resultados demuestran una relación significativa entre el conflicto de rol y el burnout-engagement, la ambigüedad de rol y el burn…
La influencia de la dependencia del medio en el comercio electrónico B2C. Propuesta de un modelo integrador aplicado a la intención de compra futura …
2008
ResumenEn el presente trabajo se evalúa la aplicabilidad del modelo de aceptación de la tecnología (TAM) para explicar la intención de compra de los internautas a través de la Red. Dicho modelo se completa con la introducción de una variable que ha recibido poca atención en el campo del B2C, la dependencia del internauta del medio Internet, dando lugar a un modelo integrador con mejor capacidad explicativa que el TAM clásico. Dado el carácter formativo del constructo «dependencia» el análisis se realiza mediante la técnica de mínimos cuadrados parciales (PLS). Del análisis de los resultados obtenidos de una muestra de 465 internautas no compradores españoles, se comprueba que el modelo TAM …
Sentiment Analysis of Twitter in Tourism Destinations
2020
[EN] Given the importance of electronic word of mouth (eWOM), this paper analyses the content of messages generated by users related to a tourist destination and shared through Twitter. We propose three research questions regarding eWOM behaviour in Twitter focused on the expertise of the reviewer, sentiment analysis of a tweet and its content.In order to address those research questions we carry out text mining analysis by retrieving existing information on Twitter (over 1500 tweets) regarding to Venice as a tourist destination.
DRIFTS Sensor: Soil Carbon Validation at Large Scale (Pantelleria, Italy)
2013
A fast and accurate measurement of soil carbon is needed in current scientific issues. Today there are many sensors suitable for these purposes, but choosing the appropriate sensor depends on the spatial scale at which the studies are conducted. There are few detailed studies that validate these types of measures allowing their immediate use. Here it is validated the quick use of a sensor in execution at Pantelleria, chosen for size, use and variability of the parameter measured, to give an operational tool for carbon stocks studies. The DRIFT sensor used here has been validated in the first 60 cm of the soil of the whole island, and it has shown predictivity higher than 90%.
Emerging Economies’ Institutional Quality and International Competitiveness: A PLS-SEM Approach
2021
The home country’s institutional framework determines the capacity to compete in the global arena. This paper discusses the linkage between institutional quality (IQ) and international competitiveness (IC). We measured institutions’ quality in emerging economies through the use of selected indicators between 2007–2017. To evaluate the proposed IQ constructs and their relationship with IC, we applied partial least squares – structural equation modeling (PLS-SEM) analysis. The model outcomes suggest that political and lack of systemic conditions have a significant and negative effect on international competitiveness, while science, technology, engineering and mathematics (STEM) resource condi…
Continuous 3-year outdoor operation of a flat-panel membrane photobioreactor to treat effluent from an anaerobic membrane bioreactor
2020
[EN] A membrane photobioreactor (MPBR) plant was operated continuously for 3 years to evaluate the separate effects of different factors, including: biomass and hydraulic retention times (BRT, HRT), light path (Lp), nitrification rate (NOxR), nutrient loading rates (NLR, PLR) and others. The overall effect of all these parameters which influence MPBR performance had not previously been assessed. The multivariate projection approach chosen for this study provided a good description of the collected data and facilitated their visualisation and interpretation. Forty variables used to control and assess MPBR performance were evaluated during three years of continuous outdoor operation by means …
HOME COUNTRY INSTITUTIONAL EFFECTS ON INTERNATIONAL COMPETITIVENESS
2023
La qualità delle istituzioni di un Paese ha un effetto significativo sulla sua performance economica. Istituzioni forti possono garantire un'allocazione efficiente delle risorse, ridurre l'incertezza e gli attriti e favorire il coordinamento tra gli agenti economici. Al contrario, istituzioni deboli determinano una riduzione degli investimenti, un rallentamento della crescita della produttività e una minore crescita del PIL. Buone istituzioni favoriscono le sinergie tra gli investimenti diretti esteri e le imprese locali, nonché le ricadute di produttività. Al contrario, istituzioni poco sviluppate possono interferire con le attività produttive e impedire lo sfruttamento delle ricadute di c…
eWOM in reward-based crowdfunding platforms: a behavioral approach
2020
[EN] Electronic word of mouth (eWOM) plays a crucial role in influencing purchasing decisions of consumers in situations governed by asymmetric information. In this context, investors in reward-based crowdfunding platforms might modify their purchasing intentions according to recommendations of peers and/or experts. The goal of this paper is to analyze the power of eWOM to shape consumers’ purchasing decisions. We do so by conducting an experiment through Amazon Mechanical Turk (AMT). This online experimental tool allows for an instant access to a large and culturally diverse subject pool, facilitating behavioral research requiring large amounts of subjects. By recreating a reward-based cro…
Exploration of Location-Based Services Adoption
2011
The purpose of this chapter is to explore aspects of user perceptions of their use of location-based services. As mobile technologies become more ubiquitous in the general population, it is reasonable to assume that individuals will consume services and software to enhance their aspirations and entertainment desires. This study begins by constructing a location-based service prototype simulation. It then conducts an experiment and analysis based on the Unified Theory of Acceptance and Use of Technology (UTAUT) model. A survey was developed to extract usage information from participants, followed by an analysis of the results using PLS. The analysis shows significant indicators that suggest …
