Measuring destination image an approach by an attribute‐based analysis
2001
Product image formation process is a valuable insight for correct understanding of consumer behaviour. When product is a tourism destination, image formation is even more important due to the inability of pretest the tourist product. This framework gives place to the present research on tourism destination image. The paper starts with a litterature review on the meaning and measurement of destination image divided into two main approaches: the conceptual and the methodological. Secondly, the results of an empirical investigation are reported: it deals with the assessment of attribute‐based destination image of sun and beach resorts on the Spanish Mediterranean coast. The aim and contributio…
The technological transplant
1990
Abstract This paper deals with technology transfer and conditions for successful diffusion of renewable energy technologies in developing countries. Issues such as perception of needs and resources are fully discussed, whether on mega-scale or micro-scale; that is to say, whether for a specific project or a whole country. A distinction is made between technology and the technological device, the latter being a component which is injected into a social system creating new links into the pre-existing structure; therefore, even if perfect in itself, it may not fit into the system in which it has to operate. The need for a complete analysis of the effects of the injection (or transplant) of the…
Feeding, cooking, sharing : a brief social history of food
2020
This work addresses the food system as a complex structure connected to the environment, like a living organism. It uses the contributions from multiple fields (including anthropology, nutritional, medicine, and economics) to establish connections between analytically disparate fields in order to highlight their transformations over time and space. It also studies social organisation over millions of years to understand the synergy between the environment, extraction technologies, economic and political structures, and the resulting cooking environments (each with their own social construction of tastes) as conditioning factors for sickness and death. In short, it delves into the anthropolo…
An analysis of ego network communities and temporal a affinity for online social networks
2017
The wide diffusion of Online Social Networks (OSNs) presents several advantages, like the definition of simple tools for information sharing and spreading. However, OSNs present also some drawbacks, one of the most important one is the problem of privacy disclosures. Distributed Online Social Networks (DOSNs), which decentralize the control of the social network, have been recently proposed to overcome these issues. The decentralization of the control has issued several challenges, one of the main ones is guaranteeing data availability without relying on a central server. To define users’ data allocation strategies, the knowledge of the structure of the ego network and of the user’ temporal…
Synthesis of new cationic donor-stabilized phosphenium adducts and their unexpected P-substituent exchange reactions
2008
The reaction between two 1,3-dialkylimidazolium-2-carboxylates 1a and 1b and two different dichlorophosphines (RPCl(2), with R = Ph and NEt(2)) led to new donor-stabilized phosphenium adducts. When the reaction was performed with the 1,3-dimethylimidazolium-2-carboxylate 1a and PhPCl(2) in a 2:1 ratio, the phosphine 4a, bearing two imidazolium moieties, was obtained and led to 5a, after an anion exchange reaction with KPF(6), the latter being fully characterized by an X-ray structure analysis. In similar conditions, the bis-imidazolium phosphine or phosphene-di-ium, 4b, which is analogous to 4a, has been obtained by the addition of PhPCl(2) to the 1-dodecyl-3-methylimidazolium-2-carboxylate…
The Bourdieu Affair
2018
In this chapter, the author analyzes Pierre Bourdieu as a representative of the French intellectual tradition. In the name of morality, he rose to defend those who suffered injustice. In the Bourdieu affair, the sufferers of injustice were the unemployed and part-time workers. The opponents were the neoliberal market ideologists, historical successors to the form of capitalism Emile Zola had already dissected in his book on the stock exchange, Avarice (greed), as well as audio-visual communication tools, which Bourdieu accused of mediocrity. As in the cases of Zola and Jean-Paul Sartre, Bourdieu’s message is universal, even though the problems selected, the form of their presentation and th…
Preparados para el desastre
2019
La actual crisis política y económica que atraviesa nuestra cotidianeidad supone también una crisis individual que afecta y pone en cuestión tanto las manifestaciones hacia el interior (subjetivas) como también hacia el exterior (de sociabilidad, de inter-subjetividad). Lo mencionado se agrava si tenemos en cuenta el complicado escenario de «colapso» al que nos abocamos según el consenso científico en materia medioambiental, entendido este como una especie de «punto cero» que podría desencadenar una catástrofe de consecuencias inimaginables. Ante este panorama, no son pocas las manifestaciones literarias o cinematográficas que en las últimas décadas se han encargado de asumir este colapso c…
Gubernamentalidad neoliberal y producción de conocimiento en la universidad: genealogía de una configuración subjetiva
2016
This article claims that any questioning of the conditions related to the feasibility of critical research projects needs to be done by taking into account the process of commodification of knowledge that has developed in universities due to the incorporation of the modes of neoliberal governmentality. This is a process which redefines the value and use that we give to produced knowledge as well as the subjectivity of university collectives. The way knowledge is understood and the subjective configurations that promote instrumental ways of relating to knowledge in an individualizing and competitive environment need to be taken into account. Therefore, we consider it politically relevant to …
Guidelines to compare additive and subtractive manufacturing approaches under the energy demand perspective
2020
In order to characterise the environmental performance of additive manufacturing (AM) processes, comparative analyses are required. Different manufacturing approaches (such as additive and subtractive ones), besides adopting different equipment, use different kinds and amounts of material. Therefore, the material-related flow has to be followed throughout the entire product life. Differences in environmental impact arise at each step of the life cycle: material production, manufacturing, use, disposal, and transportation. A life cycle-based methodology able to take due account of all the factors of influence on the total energy demand for the production of metal components is given in this …
