Preference Oriented Measurement of Advertising Response
2015
As the information overload and an extension of the mass media reduces the possibility to get the message to the target group, the firms have to increase their advertising budget to reach the same amount of ad contacts. To be sure, that they don’t waste the money, the companies more often use the instrument of pretesting the commercial campaign. The aim of this paper is to document the advantages of the conjoint-analysis (CA) as a technique for pretesting ads. To evaluate the possibility of using the CA we try in to measure in an empirical study, if informative and emotional ads have an influence on the preferences of the respondent.
Imaging of metabolic and overload disorders in tissues and organs
2023
Metabolic and overload disorders are a heterogeneous group of relatively uncommon but important diseases. While imaging plays a key role in the early detection and accurate diagnosis in specific organs with a pivotal role in several metabolic pathways, most of these diseases affect different tissues as part of a systemic syndromes. Moreover, since the symptoms are often vague and phenotypes similar, imaging alterations can present as incidental findings, which must be recognized and interpreted in the light of further biochemical and histological investigations. Among imaging modalities, MRI allows, thanks to its multiparametric properties, to obtain numerous information on tissue compositi…
Prevalencia de riesgos psicosociales en personal de la administración de justicia de la comunidad valenciana (España)
2016
El objetivo del estudio fue evaluar los factores psicosociales en el trabajo del personal de justicia de la Comunidad Valencia (España) para identificar la prevalencia de riesgos psicosociales. Participaron 402 trabajadores (28.11 % hombres) incluyendo gestores, tramitadores y auxiliares sociales. Se evaluó con la Batería UNIPSICO (incluye factores de demanda, factores de recursos y consecuencias de los riesgos psicosociales). Los principales riesgos fueron la sobrecarga de trabajo (46.02 % de participantes en situación de alto riesgo) dentro de las demandas, la falta de recursos para realizar el trabajo (76.37 % en situación de alto riesgo) y la falta de autonomía (67.41 % en situación de …
Effects of waterborne iron overload and simulated winter conditions on acute physiological stress response of whitefish, Coregonus lavaretus
2003
Two-year-old whitefish (Coregonus lavaretus) were exposed for 30 days to episodic iron overload in iron-rich humic water (5%) supplemented with inorganic iron (5 mg FeL(-1)). Two parallel laboratory exposures were performed, one under conditions simulating winter and the other under conditions simulating spring. After exposure, some of the fish were subjected to acute handling stress in the form of a short air challenge to reveal possible modification of the primary and secondary stress responses. In whitefish sampled without additional handling, iron accumulated in the liver (under spring conditions) and gills (under winter and spring conditions); plasma catecholamine and beta-estradiol (b…
Employment of vasopressin receptor antagonists in management of hyponatraemia and volume overload in some clinical conditions
2015
Summary What is known and objective Hyponatraemia, the most common electrolyte imbalance occurring in hospitalized subjects, is usually classified as hypovolaemic, euvolaemic or hypervolaemic. Hyponatraemia is a predictor of death among subjects with chronic heart failure and cirrhosis. The inappropriate secretion of the antidiuretic hormone (AVP) seems to be of pivotal importance in the decline of serum sodium concentration in these clinical conditions. The objective of this review was to summarize recent progress in management of hyponatraemia in SIADH, cirrhosis and heart failure. Methods Literature searches were conducted on the topics of hyponatraemia and vasopressin receptor antagonis…
Physical Activity and Exercise: Text Mining Analysis
2021
It is currently difficult to have a global state of the art vision of certain scientific topics. In the field of physical activity (PA) and exercise, this is due to information overload. The present study aims to provide a solution by analysing a large mass of scientific articles using text mining (TM). The purpose was to analyse what is being investigated in the PA health field on young people from primary, secondary and higher education. Titles and abstracts published in the Web of Science (WOS) database were analysed using TM on 24 November 2020, and after removing duplicates, 85,368 remained. The results show 9960 (unique) words and the most frequently used bi-grams and tri-grams. A co-…
Using Slack for computer-mediated communication to support higher education students’ peer interactions during Master’s thesis seminar
2018
Our study contributes to the research on computer-mediated communication in higher education by experimenting a modern communication tool called Slack. In particular, we consider using Slack to support students’ peer interactions during Master’s thesis work. For this purpose, we designed a case study that was executed in a Master’s thesis seminar course. During the course, all out-of-class communication was carried out by using Slack, instead of e-mails or learning management systems. After the course, we used a questionnaire to investigate how the students perceived Slack for asking for assistance, their intention to use Slack, and Slack’s ease of use. Furthermore, the questionnaire asked …
Two decades of the dark side in the information systems basket: suggesting five areas for future research
2016
Despite its benefits, information technology (IT) use is associated with serious negative effects on individuals. For example, technostress and IT addiction can harm IT users’ organizational performance and everyday well-being. Such dark side phenomena have become more evident since IT has transmuted into a major component of humans’ job routines and private lives. However, since current information systems (IS) research on the dark side is in an early and fragmented stage, there is a need for a synthesis. To address this need, we conducted a literature review of 37 articles published in the IS basket journals between 1995 and 2015. We detected four key phenomena: technostress, information …
Information management and complementary alternative medicine: the anatomy of information about CAMs through PubMed
2013
In recent years, there has been a growing interest about complementary and alternative medicine (CAM), and the use of CAM interventions has become more common among people. For these reasons, health professionals must be able to effectively manage information in this field of knowledge according to an evidence-based point of view. This study assessed the anatomy of the available information about CAMs using PubMed, to give practical instructions to manage information in this field. We also analyzed the anatomy of information according to each alternative medicine branch, narrow and broad search methods, subset filters for indexed-for-Medline and non-indexed citations, and different publicat…
Cognitive and Affective Consequences of Information and Choice Overload
2021
When interviewed in 1992 in Pittsburgh, Pennsylvania, the Nobel laureate Herbert Simon described a paradox at the heart of living in an economy that made every effort to design and produce ever more “choice alternatives” but that simultaneously allocated very little energy to encouraging people to devote the attention and time actually required to choose. He gave the example of a decision to buy a new house, commenting: “Before you even start the choice process, somebody has presented you with this, and this, and this house” (UBS, 1992). The overabundance of alternatives was lamented by Simon in 1992, when computing power was slower. It is all the more alarming in the modern and constantly …
