Relationship among Perceived Dynamism, Technological Posture and Innovation Performance
2014
A main strategic election for a firm is its technological posture, which can be understood as its propensity to innovate and the moment for the introduction of technological changes into the market. This paper, which focuses on the renewable energy industry in Spain, establishes that in environments in which dynamism is understood by managers as high, and the appreciation of change is greater, firms develop a greater tendency towards technological leadership postures (pioneer or first-mover strategy) rather than conservative or follower postures (last-mover strategy). The results of the analysis, carried out through a structural equation model based on the partial least squares (PLS) techni…
Influencia de la satisfacción y el valor percibido sobre el “Word of Mouth” en los usuarios de centros deportivos
2019
Uno de los principales objetivos de los servicios deportivos, es fidelizar a los usuarios el mayor tiempo posible en dicho servicio. Por ello, desde el inicio de la literatura de la gestión del deporte, que analizan las diferentes variables de gestión, cada vez más, aparecen trabajos que tratan de aportar información relacionada con este objetivo. Dentro de las inten- ciones futuras de los usuarios, la recomendación es uno de los factores claves para poder analizar los futuros comportamientos de dichos usuarios. Por ello este trabajo, trata de analizar cuál es la influencia de la satisfacción y el valor percibido de los usuarios, sobre el “Word of Mouth” (boca-oído), es decir, como influyen…
El efecto de la experiencia de servicio emocional en las intenciones futuras del usuario de centros deportivos
2016
El presente trabajo analiza la influencia que tienen los aspectos emocionales en las intenciones futuras de los usuarios de centros deportivos. A través de una muestra compuesta por 512 usuarios de tres instalaciones deportivas privadas y diversas escalas adaptadas de valor percibido, satisfacción general, intenciones futuras y emociones, se realiza un análisis de consistencia interna de dichas escalas, un descriptivo de media y desviación estándar, análisis de correlación de Pearson y una regresión lineal múltiple. Los resultados mostraron que las escalas utilizadas eran fiables y la valoración de los usuarios fue alta en cuanto a la satisfacción y la experiencia emocional con el servicio.…
Mindfulness, perceived stress, and subjective well-being: a correlational study in primary care health professionals
2015
Background Primary health care professionals (PHPs) usually report high levels of distress and burnout symptoms related to job strain. Mindfulness, defined as non-judgmental-present-moment awareness, seems to be a moderator in the causal association between life stressors and well-being. This study aimed to verify correlations among self-reported mindfulness, perceived stress (PS), and subjective well-being (SW) in Brazilian PHPs. Methods We performed a correlational cross-sectional study in a purposive sample of Brazilian PHPs (physicians, nurses, nursing assistants, and community health workers), working in community-oriented primary care programs (known locally as “Family Health Programs…
Nash codes for noisy channels
2012
This paper studies the stability of communication protocols that deal with transmission errors. We consider a coordination game between an informed sender and an uninformed decision maker, the receiver, who communicate over a noisy channel. The sender's strategy, called a code, maps states of nature to signals. The receiver's best response is to decode the received channel output as the state with highest expected receiver payoff. Given this decoding, an equilibrium or "Nash code" results if the sender encodes every state as prescribed. We show two theorems that give sufficient conditions for Nash codes. First, a receiver-optimal code defines a Nash code. A second, more surprising observati…
Confidence-based Somatic Mutation Evaluation and Prioritization
2012
Next generation sequencing (NGS) has enabled high throughput discovery of somatic mutations. Detection depends on experimental design, lab platforms, parameters and analysis algorithms. However, NGS-based somatic mutation detection is prone to erroneous calls, with reported validation rates near 54% and congruence between algorithms less than 50%. Here, we developed an algorithm to assign a single statistic, a false discovery rate (FDR), to each somatic mutation identified by NGS. This FDR confidence value accurately discriminates true mutations from erroneous calls. Using sequencing data generated from triplicate exome profiling of C57BL/6 mice and B16-F10 melanoma cells, we used the exist…
Performance of Fine-Tuning Convolutional Neural Networks for HEp-2 Image Classification
2020
The search for anti-nucleus antibodies (ANA) represents a fundamental step in the diagnosis of autoimmune diseases. The test considered the gold standard for ANA research is indirect immunofluorescence (IIF). The best substrate for ANA detection is provided by Human Epithelial type 2 (HEp-2) cells. The first phase of HEp-2 type image analysis involves the classification of fluorescence intensity in the positive/negative classes. However, the analysis of IIF images is difficult to perform and particularly dependent on the experience of the immunologist. For this reason, the interest of the scientific community in finding relevant technological solutions to the problem has been high. Deep lea…
Hybrid chaotic firefly decision making model for Parkinson’s disease diagnosis
2020
Parkinson’s disease is found as a progressive neurodegenerative condition which affects motor circuit by the loss of up to 70% of dopaminergic neurons. Thus, diagnosing the early stages of incidence is of great importance. In this article, a novel chaos-based stochastic model is proposed by combining the characteristics of chaotic firefly algorithm with Kernel-based Naïve Bayes (KNB) algorithm for diagnosis of Parkinson’s disease at an early stage. The efficiency of the model is tested on a voice measurement dataset that is collected from “UC Irvine Machine Learning Repository.” The dynamics of chaos optimization algorithm will enhance the firefly algorithm by introducing six types of chao…
Ellenberg’s Indicator values for the Flora of Italy – first update: Pteridophyta, Gymnospermae and Monocotyledoneae
2012
Ellenberg’s indicator values are an useful tool to delineate the relationship between plants and environment, recognising to each species a functional role as biological indicator. In the frame of the second edition of the Pignatti’s “Flora d’Italia”, some new informative systems are under preparations, in order to support geobotanical/applied studies, including a complete and updated review of the Ellenberg’s indicator values for the whole bulk of species mentioned in the flora of Italy. This first contribution includes a list of 380 species of Pteridophyta, Gymnospermae and Monocotiledoneae that complete the first assignment of the Ellenberg’s indicator values to the flora of Italy, publi…
