Imagem de destinos turísticos: um estudo sobre as publicações brasileiras

Os estudos referentes ao turismo dedicam-se à compreensão de diferentes temas, sendo que um bastante analisado à escala internacional é a questão da imagem de um destino turístico. O interesse por este tema é percebido em diversas áreas do conhecimento, como a sociologia e o marketing. No Brasil, há diversos pesquisadores dedicando-se à imagem dos destinos turísticos. Assim, buscando compreender de que forma este tema tem sido trabalhado no Brasil, este estudo de caráter bibliográfico teve como objetivo analisar e compreender as publicações sobre imagem de destinos turísticos em periódicos brasileiros, nos últimos seis anos (2008-2014). A partir de um levantamento dos artigos publicados neste período, usando como ferramenta de busca o site “Publicações de Turismo”, foram identificados vinte e oito artigos. A análise permitiu verificar que os estudos estão concentrados na compreensão da imagem de um determinado destino. Os artigos analisados são predominantemente estudos empíricos e há um equilíbrio entre os de caráter quantitativo e qualitativo. No que diz respeito à bibliografia, foi possível identificar que os autores brasileiros que têm trabalhado com o tema de imagem de destinos, já buscam bibliografias internacionais para fundamentar os seus estudos. Também nos trabalhos sobre este tema, identificou-se uma maior maturidade dos autores no que diz respeito à utilização das ferramentas estatísticas. Alguns estudos fazem uma análise aprofundada dos estudos internacionais e aplicam estas teorias no Brasil. Conclui-se que este tema tem sido estudado com maior profundidade no país, se comparado com os temas como o da percepção de residentes.

Contribution to an efficient transmission of information to the textile fashion consumer and the influence in sustainable attitudes

The concepts involved in sustainable textile fashion, demanding good knowledge about raw materials, processes, end use properties and circuits amongst others, are able to determine the way the textile product is designed and the behavior of the consumer, regarding life style and buying decisions. The textile product`s life integrates raw materials, their processing, distribution, use by the consumer and destination of the product after useful lifetime, this is, his complete life cycle. It is very important to recognize the power of the consumer to influence parameters related to sustainability, namely when he decides how, when and why he buys and afterwards by the attitudes taken during and after use. The conscious act of consumption involves ethical, ecological and technical knowledge in which the concern is overall lifecycle of the fashion product and not exclusively aesthetic and symbolic values strongly related with its ephemeral nature. The present work proposes the classification of textile products by means of an innovative label aiming to establish a rating related to the Life of Fashion Products, by using parameters considered with especial impact in lifecycle, as textile fibers, processing conditions, generated wastes, commercialization circuits, durability and cleaning procedures. This label for sustainable fashion products aims to assist the stakeholders with informed attitudes and correct decisions in order to promote the objectives of sustainable fashion near designers, consumers and industrial experts.

Participación del tráfico y la distribución de proteínas en la polaridad y el desarrollo de procesos neuronales. Protein sorting and trafficking participation in neuronal processes polarity and development.

El estudio del tráfico intracelular en neuronas ha despertado gran interés en los últimos años, debido a que un gran número de enfermedades neurodegenerativas y neuropsiquiátricas parecen tener origen en en el transporte defectuoso de proteínas en estos tipos celulares. Mediante el uso de técnicas de biología celular y molecular, fuimos capaces de describir una de las vías que regula la fisión de las vesículas que llevan su cargo desde la última cisterna del Aparato de Golgi hacia la superficie celular en células epiteliales no polarizadas. Uno de los componentes clave de esa vía resultó ser la Proteina Kinasa D1 (PKD1), cuya actividad en el Aparato de Golgi es esencial para un normal transporte intracelular. Sorprendentemente, observamos que la PKD1 en neuronas con polaridad establecida no regula la fisión en el Golgi, pero si estaría involucrada en la selectividad y distribución (sorting) de vesículas cuyo cargo debe ser específicamente dirigido a las membranas dendríticas. El bloqueo de la actividad de la PKD1 no solamente cambia el destino final de estos cargos, que son enviados de esta forma a la membrana terminal del axón, sino que también es capaz de inducir defectos en el desarrollo y crecimiento de los procesos dendríticos a largo plazo. En este proyecto estudiaremos de que manera influye la perturbación del sorting, en ausencia de PKD1 activa y de otros componentes que la regulan, en la distribución de receptores de factores neurotróficos y de neurotransmisores glutamatérgicos, y cómo estos cambios en su distribución afectan el número, tamaño, y funcionalidad de los procesos neuronales (axones y dendritas). Estos resultados contribuirán a adquirir mayores conocimientos de los mecanismos dependientes del transporte y sorting de proteínas de membrana que participan en la regulación del crecimiento neuronal, los cuales a su vez aportarán información valiosa en la comprensión de un gran número de enfermedades neurológicas. The study of intracellular trafficking in neurons has arisen a great deal of interest in the last years, since a great number of neurodegenerative and neuropsychiatric disorders seem to be originated in abnormal protein transport in these type of cells. Using cell and molecular biology methodologies, we have been capable of describe one of the pathways that regulate the fission of vesicles that carry their cargo from the last Golgi Apparatus cisternae to the cell surface in non-polarized epithelial cells. One of the key components in this pathway is the Protein Kinase D1 (PKD1), whose activity in the Golgi Apparatus is essential for a normal intracelular transport. Surprisingly, we have observed that PKD1 does not regulate fission in neurons with established polarity, but it would be involved in vesicles' sorting at Golgi, particularly of those that carry specific dendritic cargo. Blocking PKD1 activity changes the final destination of these cargoes, which is now sent to the axons' terminal membranes, and also produces late dendritic development and growing defects. In this project we will study how sorting perturbation in absence of PKD1 and its regulators activities influences selectivity and distribution of neurotrophic and neurotransmitter receptors, and how these sorting changes affect number, size and functionality of neuronal processes (axons and dendrites). These results will help to acquire greater knowledge about transport and sorting mechanisms of neuronal growth regulatory membrane proteins. In addition, these studies will contribute with new valuable information necessary to understand numerous neurological diseases.

Green furniture: sustainable design guidelines for the Irish furniture and wood products industry.

This thesis presents the research and development of sustainable design guidelines for the furniture and wood products industry, suitable for sustainably enhancing design, manufacturing and associated activities. This sustainable guideline is based on secondary research conducted on subject areas such as ‘eco’ design, ‘green’ branding and ‘green’ consumerism, as well as an examination of existing certifications and sustainable tools techniques and methodologies, national and international drivers for sustainable development and an overview of sustainability in the Irish furniture manufacturing context. The guideline was further developed through primary research. This consisted of a focus group attended by leading Irish designers, manufacturers and academics in the area of furniture and wood products. This group explored the question of ‘green branding’ saturation in the market and the viability of investing in sustainability just yet. Participants stated that they felt the market for ‘green’ products is evolving very slowly and that there is no metric or legal framework present to audit whether or not companies are producing products that really embody sustainability. All the participants believed that developing and introducing a new certification process to incorporate a sustainable design process was a viable and necessary solution to protecting Irish furniture and wood manufacturers going forward. For the purposes of the case study, the author investigated a ‘sustainable’ design process for Team woodcraft, Ltd., through the design and development of a ‘sustainable’ children’s furniture range. The case study followed a typical design and development process; detailing customer design specifications, concept development and refinement and cumulating in final prototype, as well as associated engineering drawings. Based on this primary and secondary research, seven fundamental core principles for this sustainable guideline have been identified by the author. The author then used these core principles to expand into guidelines for the basis of proposed new Irish sustainable design guidelines for the furniture and wood products industry, the concept of which the author has named ‘Green Dot’. The author suggests that the ‘Green Dot’ brand or logo could be used to market an umbrella network of Irish furniture designers and manufactures who implement the recommended sustainable techniques.

Cooperative Transmission and Radio Resources Management for Wireless Networks

Report for the scientific sojourn at the Multimedia Communications Laboratory, University of Texas at Dallas, USA, from September to December 2005. The cooperative transmission has been analyzed taking a broadcast relay channel which assumes a scenario with one source and multiple destinations. Moreover, in order to improve the performance in terms of mutual information, it has been considered that for each destination there is another nearby terminal (called relay) which will help to improve the performance of the destination. This scheme combines different types of channels considered in the information theory, such as the relay channel, broadcast channel and interference channel (if the relays transmit information intended only to its associated destination). In this work, the author has studied the optimal way to encode the signals for the different users, known as capacity region (i.e. related to radio resources management ), of the broadcast relay channel.

Els camins "verd" i "daurat" cap a l'accés obert: arguments a favor de combinar i relacionar

Els debats recents sobre l'accés obert (OA) han tendit a tractar les revistes d'OA i l'auto-arxiu com dues rutes diferents. Alguns partidaris de l'auto-arxiu fins i tot han suggerit que per si sol aquest pot conduir a l'accés obert complet de la literatura científica mundial. En aquest article es discuteix que, de fet, cada camí correspon a una fase del moviment cap a l'accés obert; que amb el simple fet de l’auto-arxiu no n'hi ha prou, i que cal que els dipòsits proporcionin alguna capacitat de crear marques. De totes maneres, fer això desembocaria, finalment, en la creació d'overlay journals (o bases de dades). Per tant, els dos camins es fusionarien per crear un paisatge d'OA madur.
