Uztvertais stress un sociālais atbalsts pirmā kursa studentiem
2016
Šī pētījuma mērķis ir noskaidrot, vai saņemtais sociālais atbalsts saistās ar uztvertā stresa līmeni. Pētījumā piedalījās 120 Latvijas universitātes pirmā kursa studenti no četriem studiju virzieniem – psiholoģijas, medicīnas, fizikas un jurisprudences bakalaura programmas. Pētījumā tika pielietotas divas aptaujas. Pirmā ir “Uztvertā stresa skala” aptauja (PSS- Perceived Stress Scale, Cohen, Kamarc & Mermelstein, 1983), Latvijā aptauju adaptējusi Stokenberga I., 2002. Otrā aptauja ir “Saņemtā sociālā atbalsta skala” (MSPSS- Multidimensional Scale of Perceived Social Support, Dahlem, Zimet & Farley, 1988), Latvijā aptauju adaptējusi Voitkāne, S. & Miezīte, S., (2001).

Customer Loyalty in Clusters: Perceived Value and Satisfaction as Antecedents
2009
Purpose: This paper studies, from the perspective of relationship marketing, the loyalty behavior of industrial customers in the context of a cluster. Loyalty is a key variable for studying long term relationships between firms. Research implications: Recent advances in consumer and services marketing consider that perceived value and satisfaction are central to explaining customer loyalty. However, very few studies in B2B explain the antecedents of customer loyalty. This study adopts the relationship marketing approach, and loyalty behavior is being analyzed in a specific setting: an industrial cluster. Furthermore, the effect of the number of suppliers is analyzed as a possible moderator …
What do users associate with ‘interactivity’?
2009
‘Interactivity’ was one of the major buzzwords of the 1990s. Although the academic discourse has produced a large number of different concepts of ‘interactivity’, in everyday life it still remains a label put on all kinds of aspects of online communication and digital media. Drawing on schema theory this article explores the concepts of ‘ordinary’ users (i.e. people who are not professional experts). The results indicate that users associate the foremost social and individual issues with the term ‘interactivity’, i.e. what they can accomplish by using media in terms of self-development, social influence and social relationships.

Improved prediction of survival by a risk factor-integrated inflammatory score in Sorafenib treated hepatocellular carcinoma
2017
Background and aims Inflammation affects progression of hepatocellular carcinoma (HCC). We therefore postulate that systemic inflammatory markers could help to predict prognosis in HCC patients receiving sorafenib therapy. Methods Overall survival (OS) of HCC patients receiving palliative sorafenib treatment was correlated with the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), C-reactive protein to albumin ratio (CAR), Glasgow prognostic score (GPS) and the modified GPS (mGPS) along with clinicopathological parameters. Predictors of OS were assessed by multivariable Cox regression and receiver operating characteristics and area under the curve (ROC-AUC) analyses.…
Sparse multipath channels: Modelling, analysis, and simulation
2013
A sparse multipath channel is characterized by a small number of randomly distributed scatterers. This study proposes a methodology for the modelling of sparse multipath channels. The new methodology is then used to develop a sparse narrowband multipath channel model by applying the sum-of-cisoids (SOC) principle. The statistical properties of the presented sparse SOC multipath channel model are studied. Analytical expressions are derived for the mean value, variance, autocorrelation function (ACF) and cross-correlation function (CCF) of the complex channel gain, as well as for the probability density function (PDF) of the envelope. Our study shows that mobile radio channels behave in spars…
Asthma control, severity and lung function impairment through network analysis in children
2015
Background: Achieving and maintaining asthma control in children is the primary goal recommended by current guidelines. Aim: To identify risk factors associated with Asthma control and severity, as well as their relative weight. Methods: Within a consecutive series of outpatients visited in a three years period at the IBIM pediatric clinic, we selected 128 persistent asthmatics. A standardized medical interview was carried out to collect information on environmental risk factors, symptoms and comorbidities. Spirometry was performed using Pony FX, Cosmed, Italy; spirometric values were expressed as %pred using GLI-2012equation. Statistical analyses were performed by using R. Results: The ide…
Transferencia valor-experiencia a través del patrocinio deportivo : antecedentes y consecuencias
2021
El estudio propone un modelo de patrocinio deportivo que toma como eje la transferencia entre evento y marca en términos de valor y experiencia, abundando en sus antecedentes y efectos. Encuestando en 2012 a 364 asistentes al GP de Fórmula 1 de València se concluye que no se transfiere el valor del evento a la marca, pero sí la experiencia. Asimismo, se observa que ambos términos (experiencia y valor) están significativamente relacionados. Adicionalmente, se confirma que motivación, identificación e implicación son antecedentes del eje del modelo, junto con todos los efectos propuestos. This study proposes a general model for sports sponsorship which takes as its central concept the transfe…
High commitment HR practices, the employment relationship and job performance: A test of a mediation model
2016
Abstract Purpose This study outlines and tests a high commitment model of human resource (HR) practices and its association with outcomes through a path including employee perceptions and attitudes, thereby seeking a new way of opening the so-called ‘black box’ between human resource management (HRM) and performance. Methodology Data were collected through a questionnaire survey with responses from 835 Spanish workers from three sectors (services, education and food manufacture). In order to test hypotheses, we conducted a path analysis. Findings High commitment HR practices were related to employee performance through the mediating effect of perceived organizational support, a fulfilled ps…
What drives the helpfulness of online reviews? A deep learning study of sentiment analysis, pictorial content and reviewer expertise for mature desti…
2021
Los destinos turísticos se ven cada vez más afectados por la información relacionada con los viajes que se comparte a través de las redes sociales. Basándose en teorías de proceso dual sobre cómo los individuos procesan la información, este estudio examina el papel de las rutas de procesamiento de información central y periférica en la formación de las percepciones de los consumidores sobre la utilidad de las reseñas en línea de destinos maduros. Llevamos a cabo un proceso de dos pasos para abordar la utilidad percibida del contenido generado por el usuario, un análisis de sentimiento utilizando técnicas avanzadas de aprendizaje automático (aprendizaje profundo) y un análisis de regresión. …
