Incentive Mechanism for Edge-Computing-Based Blockchain
2020
Blockchain has been gradually applied to different Internet of Things (IoT) platforms. As the efficiency of the blockchain mainly depends on the network computing capability, how to make sure the acquisition of the computational resources and participation of the devices would be the driving force. In this work, we focus on investigating incentive mechanism for rational miners to purchase the computational resources. A edge computing-based blockchain network is considered, where the edge service provider (ESP) can provide computational resources for the miners. Accordingly, we formulate a two-stage Stackelberg game between the miners and ESP. The aim is to investigate Stackelberg equilibriu…
<em>El dibujado</em>: volver a la pared
2021
The exhibition El dibujado by Paco Roca (IVAM, 2019) is an exploration of the paradigm shift brought forth by the abandonment of paper and reproducibility as a space for the dissemination of the comic strip. The exhibition hall of a museum (the Instituto Valenciano de Arte Moderno) becomes a space for formal and ephemeral experimentation at different levels, from the purely creative to the pondering about the unexplored possibilities of the language of the comic book. With this exhibition cartoonist Paco Roca poses a challenge to a spectator who is called to leave his/her role as a visitor and become the reader of an experience in which s/he becomes a part of the work’s own narrative. The a…
Powered by public relations? Mutual perceptions of PR practitioners’ bases of power over journalism
2017
Public relations practitioners depend on journalists to report information, and journalists count on public relations practitioners to provide information. This mutual dependence gives the two parties a degree of power over each other that can be wielded if certain resources are available. However, there are many unanswered questions about how public relations exerts power over journalists and how these influence attempts may affect news coverage. We differentiate six bases of power that public relations practitioners may use to influence journalists. To test the use of these bases of power, we conducted a quantitative survey among German journalists and public relations practitioners. Our…
Analyzing the metrics of the perceptual space in a new multistage physiological colour vision model
2009
In this work, the metric of a new multistage colour vision model, ATTD05, is assessed and a new colour difference formula is suggested. Firstly, the uniformity of the ATTD05 colour space was compared with that of CIECAM02 for some Munsell samples, because if the model yields a uniform perceptual space, we will be able to implement a colour difference formula as a Euclidian distance between two points. Secondly, we developed a new space based on the perceptual descriptors of the model: brightness, hue, colourfulness, and saturation. After that, we calculated the free parameters of the space that better fit the measured and experimental data of two datasets (small-magnitude and large-magnitud…
Latent Semantic Description of Iconic Scenes
2005
It is proposed an approach for the automatic description of scenes using a LSA–like technique. The described scenes are composed by a set of elements that can be geometric forms or iconic representation of objects. Every icon is characterized by a set of attributes like shape, colour and position. Each scene is related to a set of sentences describing their content. The proposed approach builds a data driven vector semantic space where the scenes and the sentences are mapped. A new scene can be mapped in this created space accordingly to a suitable metric. Preliminary experimental results show the effectiveness of the procedure.
A Conversational Agent Based on a Conceptual Interpretation of a Data Driven Semantic Space
2005
In this work we propose an interpretation of the LSA framework which leads to a data-driven “conceptual” space creation suitable for an “intuitive” conversational agent. The proposed approach allows overcoming the limitations of traditional, rule-based, chat-bots, leading to a more natural dialogue.
Measuring the market power in the ceramic tile industry: An international comparison
2004
This paper measures the degree of competition faced by Spanish and Italian exporters of ceramic tiles in several European Union member states. The results indicate that Spanish producers have a substantial market power while Italian exporters face a high degree of competition. This finding is consistent with the significant gain (loss) in the world production and export shares that Spanish (Italian) producers experienced during the 1990s. The results are also consistent with accounting data. Furthermore, comparisons in the extent of market power across source countries and European destination markets reveal that most variation in the data is related to the source country. JEL no.

Employer Branding Training Development for Public Organisations
2021
In the condition of demographic issues in Europe and competition for specialist between public and private sector on the labour market public organisations’ as employers’ image is an important aspect of development. The research aim is to identify principles of Employer Branding (EB) and ways public organisations can organize and develop employees’ education on this topic. There are EB activities examined in ten socially responsible (SR) organisations from public sector in Latvia. Authors prepare theoretical bases for the research analysing scientific literature to explain the main point of the approaches framework and define the main terms in depth implementing qualitative and quantitative…
Bidding for Research Funds. Inter-Fields Differences and Predictors of the Evaluation Scores: Insights from a Romanian National Competition for Postd…
2021
This study sought to address an important gap in the existent knowledge about the development of the Romanian research system by looking at a very specific population of young scholars who participated in the national competition for postdoctoral grants (2016) which included over 900 participants. The paper is structured by two main research objectives. Firstly, the analysis if focused on differences between scientific fields by looking at research entities which host young scholars’ grant proposals, gender balance, young scholars’ academic performance measured through a standardized indicator (Google Scholar H index), share of people trained abroad, and information about the evaluation pro…
Linking Online Marketing Practices in Romania to Global Trends
2018
The very fast online transformations cause rapid changes in consumers’ behavior and, implicitly, the need for businesses’ adaptation to market trends and wants. We are now at that moment when a business’s survival and development essentially depend on understanding the importance of marketing and on adjustment to online marketing trends like ultimate elements in bringing its success. Thus, online marketing is a business culture, an entrepreneurial mindset in all over the world, for each type of business. This paper aims to give an overview on Romanian online advertising market by presenting data, trends, and main players. Many recent studies showed that the online is in a growing process, a…
