Comunicaciones de marketing y valor de marca de un festival musical
2017
La creación de capital de marca es fundamental para diferenciar los productos y alcanzar una ventaja competitiva. Sin embargo, este constructo ha recibido escasa atención en la investigación en turismo de eventos. Por ello, el objetivo del presente trabajo es analizar la influencia de las comunicaciones controladas y no controladas por la organización sobre la formación del valor de marca de un evento, y estimar el impacto del valor de marca global sobre la satisfacción y las intenciones conductuales del asistente al evento. Centrándonos en un festival de música en vivo, a partir de una muestra de 622 asistentes, se obtiene evidencia acerca de la efectividad de las comunicaciones del evento…
Clarifying Communication Professionals’ Tasks In Contributing To Organizational Decision Making
2017
The purpose of this paper is to discuss the tasks through which communication professionals and public relations contribute to organizational decision making. In-depth interviews were conducted with Finnish public relations professionals about how they contribute to organizational decision making. The findings provide a rich picture of the tasks in relation to this. The results show that public relations professionals contribute to organizational decision-making processes by nine different tasks. Furthermore, the results indicate that during an organizational decision-making process, professionals switch from one task to another over time, and work simultaneously on several tasks. This pape…
A Study into the Integration of ICT into a Business Management Course: Challenges and Achievements
2012
Nowadays, the Information and Communications Technologies (ICT) play an increasingly important role in education. Indeed, ICT are considered as very useful pedagogic tools, and multimedia resources are constantly being created, updated and shared by university members worldwide. This paper deals with a case of study exploring the way in which the integration of ICT impacts learning in the context of a business management course at the Universitat de València (UV), in Spain. The results of the study point out the need for academic staff and students to acquire the appropriate knowledge and to develop the skills required for an efficient and effective use of ICT in higher education. Keywords:…
Attitude measurement by artificial vision
2005
The recent development of light and low-cost airborne platforms (microlight, drones, kites, balloons,...) has led to the need for simple and low-cost devices allowing attitude measurement with respect to a reference horizon of the platform itself or of an embedded setting. A theoretical study of the conditions for measuring attitude angles from artificial vision is proposed and an original practical algorithm allowing these measurements to be performed in real time is described. An implementation in a CMOS retina circuit is also presented. These points are illustrated by experiments confirming the feasibility of the device.
TCP Performance in Mobile Ad hoc Networks
2013
International audience; In this paper, we present a survey of TCP (Transmission Control Protocol) protocol for better performance in the MANET (Mobile Ad Hoc Network). After a short presentation of the main features of TCP, we give the most important problems from which TCP suffer in MANET. We present after that some approaches proposed in the literature in order to improve its performance. Our paper contains also a performance evaluation of TCP NewReno and TCP Vegas transport protocols under AODV and DSR routing protocols. The simulations are conducted under varying conditions of number of TCP connections, number of nodes and mobility.
Mapping Carbon Stocks In Central And South America With Smap Vegetation Optical Depth
2019
Mapping carbon stocks in the tropics is essential for climate change mitigation. Passive microwave remote sensing allows estimating carbon from deep canopy layers through the Vegetation Optical Depth (VOD) parameter. Although their spatial resolution is coarser than that of optical vegetation indices or airborne Lidar data, microwaves present a higher penetration capacity at low frequencies (L-band) and avoid cloud masking. This work compares the relationships of airborne carbon maps in Central and South America with both (i) SMAP L-band VOD at 9 km gridding and (ii) MODIS Enhanced Vegetation Index (EVI). Models to estimate carbon stocks are built from these two satellite-derived variables.…
Credit card incidents and control systems
2012
Abstract Credit and debit cards have spread and skyrocketed all around the world to become the most popular means of payments in many countries. Despite their enormous popularity, cards are not free of risk. Technology development and e-commerce have exponentially increased internal credit card incidents. This paper identifies and quantifies the different types of credit card fraud and puts into question the effectiveness of the role assigned to cardholders in its detection.
‘I changed my life’s course’ : The impact of the Helsingin Sanomat Foundation fellowship on the career path of a journalist
2017
This study focuses on the fellowship program of Helsingin Sanomat Foundation, which has sent a hundred mid-career journalists from Finland to study abroad at prominent universities. Based on two surveys, one on the fellows (n = 45) and one on a control group (n = 52), the article discusses the impact the fellowship education has on the journalists and their careers. The surveys are complemented with in-depth interviews of 10 fellow journalists. The results are discussed in the context of protean career concept, and they indicate that the fellowship period has a notable positive impact on the career of an individual journalist, but a contradictory impact on the journalist’s home organizatio…
Consumer attitude toward using smart shopping carts: a comparative analysis of Italian and Croatian consumer attitudes
2016
This paper aims to explore consumer attitudes toward using smart shopping cart, considering country of origin, gender, age, and intentions to use smart shopping carts while purchasing. Moreover, it investigates the influence of extracted factors on consumers' attitudes toward using smart shopping carts and the users' levels of digital competence. The data was collected through survey questionnaires using a purposive sample of 313 Croatian and Italian respondents. To this end, we applied statistical methodologies such as binary logistic regression, factor analysis, and analysis of variance. We found that, compared with Croatians, Italian respondents have a more positive attitude toward using…
Ceramide Mediates Acute Oxygen Sensing in Vascular Tissues
2014
AbstractAims: A variety of vessels, such as resistance pulmonary arteries (PA) and fetoplacental arteries and the ductus arteriosus (DA) are specialized in sensing and responding to changes in oxygen tension. Despite opposite stimuli, normoxic DA contraction and hypoxic fetoplacental and PA vasoconstriction share some mechanistic features. Activation of neutral sphingomyelinase (nSMase) and subsequent ceramide production has been involved in hypoxic pulmonary vasoconstriction (HPV). Herein we aimed to study the possible role of nSMase-derived ceramide as a common factor in the acute oxygen-sensing function of specialized vascular tissues. Results: The nSMase inhibitor GW4869 and an anticera…
