Comunicar con los visitantes: una nueva faceta profesional para los conservadores-restauradores

Heritage resources are more exposed than ever to visitors. For this reason, the transmission of cultural content is not enough: the present situation demands the inclusion of some messages able to foment a sustainable relation between the visitor and the resource. And this can best be achieved with the Preventive Difusion, a sensitizing strategy to inform and persuade visitors about the extreme fragility of the heritage resources. In addition, this strategy is a magnificent tool at the service of the corporate identity of the heritage resources and of the conservators: usually, preventive conservation actions and policies are not clear to visitors. But if they are included into the visit discourse, the public receive an accurate vi-sion of the efforts done in that sense, and it allows them to have a clear idea of these efforts, leading to the image that they have about the resource in question and, by extension, of their conservators.

Disseny d'un sistema de control del consum d'aigua automàtic

Avui en dia s’ha convertit en una necessitat tenir cura del medi ambient i optimitzar els recursos naturals. En el camp per estalviar energia s’han fet grans progressos i disposem d’un gran ventall de dispositius que ens ajuden i ens faciliten l’optimització del consum d’energia. Però és una realitat que en l’estalvi del consum d’aigua el progrés ha estat molt menor i es limita molt a donar consells i repartir dosificadors d’aigua. Qui no ha vist carrers o jardins o cases inundades amb milers de litres d’aigua? Aquesta realitat m’ha portat a dissenyar i desenvolupar un prototip que em permeti tenir un millor control del consum d’aigua. El prototip, a trets principals, consta d’un sensor, una electrovàlvula i una placa Arduino Atmega. El sensor ens permet mesurar els litres consumits durant un cert període de temps. Passat aquest temps de mostreig es compara els litres consumits amb el consum habitual, en aquell període de temps. En cas de sobrepassar el volum programat es tancarà l’electrovàlvula de forma automàtica i rebrem un SMS al telèfon. L’activació de l’alarma es pot ajustar que sigui al igualar-se els dos valors, litres programats i litres consumits. També es pot programar el percentatge que cal sobrepassar de litres consumits per activar l’alarma, com el temps de mostreig. El fet de poder programar tots aquests valors ens permet fer un ajust ideal per a la instal·lació que es vol tenir controlada. A més, el prototip es pot utilitzar per enviar a la companyia d’aigua el valor del comptador de forma automàtica. D’aquesta forma la companyia d’aigua també optimitza recursos estalviant-se el desplaçament de personal a la instal·lació per fer la lectura corresponent. El prototip està basat amb un Arduino Atmega que ens permet el processament de les dades programades i capturades pel sensor. També s’ha incorporat una pantalla TFT Touch 2’8”, que permet visualitzar i programar els valors d’una forma molt més intuïtiva. Per enviar els SMS s’utilitza una placa d’Arduino Cel·lular Shield - SM5100B, a la qual només cal afegir una targeta SIM. A priori, el prototip té un elevat cost al fabricar una sola unitat i pot semblar poc útil. Però ens pot estalviar alguna sorpresa en les factures d’aigua si tenim una fuita i no ens n’adonem fins a veure el rebut de la companyia. Si es fabriqués a grans quantitats es podria abaratir el preu i fer-lo encara més engrescador.

Characterization of the freesound online community

There are many online communities with membergenerated and openly available multimedia content. Their successdepends on having active contributing users and on producing useful content. With this criterion, the community of sound practitioners that has emerged in Freesound is a successful case of interest to be studied. But to understand it and support it further we need an appropriate analysis methodology. In this paper we propose some qualitative and quantitative approaches for its characterization, focusing on the analysis of organizational structure, shared goals, user interactions and vocabulary sharing. We think that the proposed approach can be applied to otheronline communities with similar characteristics.

El relato audiovisual publicitario del siglo XXI. Del medio televisión al medio internet. ¿Nuevos medios o nuevas formas de consumo audiovisual?

Estudiar la comunicación publicitaria del siglo XXI nos permite entender la importancia del desarrollo actual de este tipo de comunicación. Sin duda un desarrollo que afecta enormemente en el modo en que las marcas llevan a cabo sus estrategias de publicidad con su público. Pero sin duda el formato audiovisual sigue siendo el formato más utilizado por anunciantes y agencias para contactar con su público. El siglo XX estuvo definido por el desarrollo del medio televisión, el siglo XXI por el desarrollo del medio internet, pero la pregunta que realmente nos plantea este cambio mediático es conocer si estamos hablando de un cambio de medio o de un cambio en las estrategias y formatos publicitarios audiovisuales utilizados para llegar al receptor. Los mensajes publicitarios actuales resaltan por una mayor interactividad con el espectador, un contacto voluntario de éste, en muchos casos, con nuestra campaña e incluso una participación activa de nuestro consumidor en la distribución de la campaña. Los formatos evolucionan, también la relación del consumidor con el mensaje publicitario audiovisual y el producto

Why do they separate it or not? Attitudes and behaviors towards organic waste separation

This article shows the results of an exploratory study related to the separation of organic waste in order to offer suggestions for the improvement of waste disposal communication campaigns. The overall objective is to analyze attitude and behavior of those who do and those who do not separate organic waste, related to a specific promotional campaign carried out in two neighborhoods, in the municipality of Badalona (Spain), within the framework of the study of proenvironmental attitudes and behaviors and based on the Psychosocial Four Spheres Model. 1,010 interviews were conducted and data was analyzed using Chi-Squared Automatic Interaction Detector (CHAID). Waste separation behavior was used as a dependent variable. The reasons given to explain why people do or do not separate organic waste and sociodemographic variables, have been introduced as independent variables. In accordance with the Four Spheres Model, results show significant differences in waste separation. Based on the profiles obtained, we find some predictive variables that facilitate the development of communication campaigns according to the requirements of each community.

Steganalytic methods for the detection of histogram shifting data-hiding schemes

In this paper, some steganalytic techniques designed to detect the existence of hidden messages using histogram shifting methods are presented. Firstly, some techniques to identify specific methods of histogram shifting, based on visible marks on the histogram or abnormal statistical distributions are suggested. Then, we present a general technique capable of detecting all histogram shifting techniques analyzed. This technique is based on the effect of histogram shifting methods on the "volatility" of the histogram of differences and the study of its reduction whenever new data are hidden.

La Campanya gastronòmica del Peix Blau Ganxó: dels seus orígens a l'actualitat

La realització d’aquest estudi té per objectiu principal analitzar l’activitat promocional de la Costa Brava, com ho és la campanya gastronòmica del Peix Blau Ganxó. Es tracta d’analitzar quina ha estat la seva evolució des de què va néixer la campanya fins a l’actualitat. S’estudien diferents aspectes com, per exemple, l’èxit que ha anat obtenint, les maneres de promoció que s’han anat utilitzant per difondre la campanya, les empreses col•laboradores, a quins diaris s’hi han publicat notes de premsa i alguns aspectes d’imatge gràfica. Un segon objectiu és realitzar un treball de recerca basat en l’organització de la campanya gastronòmica en la seva setzena edició. Això permet desenvolupar un projecte ben documentat i en el qual s’ha pogut extreure la informació necessària de primera mà. Un tercer objectiu és donar a conèixer una de les activitats gastronòmiques amb més ressò del Baix Empordà. Són moltes campanyes de gastronomia que es celebren als diferents municipis de la comarca. Algunes d’elles tenen una trajectòria exitosa de més de 15 anys. La idea és estudiar-ne una en concret per a valorar com es desenvolupa una activitat d’aquesta mena que no té altre objectiu primordial que el d’atraure el turisme i desestacionalitzar la temporada de la Costa Brava

Social Media in health. What are the safety concerns for healthcare consumers?

Recent literature has discussed the unintended consequences of clinical information technologies (IT) on patient safety, yet there has been little discussion about the safety concerns in the area of consumer health IT. This paper presents a range of safety concerns for consumers in social media, with a case study on YouTube. We conducted a scan of abstracts on 'quality criteria' related to YouTube. Five areas regarding the safety of YouTube for consumers were identifi ed: (a) harmful health material targeted at consumers (such as inappropriate marketing of tobaccoor direct-to-consumer drug advertising); (b) public display of unhealthy behaviour (such as people displaying self-injury behaviours or hurting others); (c) tainted public health messages (i.e. the rise of negative voices againstpublic health messages); (d) psychological impact from accessing inappropriate, offensive or biased social media content; and (e) using social media to distort policy and research funding agendas. The examples presented should contribute to a better understanding about how to promote a safe consumption and production of social media for consumers, and an evidence-based approach to designing social media interventions for health. The potential harm associated with the use of unsafe social media content on the Internet is a major concern. More empirical and theoretical studies are needed to examine how social media infl uences consumer health decisions, behaviours and outcomes, and devise ways to deter the dissemination of harmful infl uences in social media.
