Tourist photographers and the promotion of travel: the Polytechnic Touring Association, 1888–1939

The Polytechnic Touring Association (PTA) was a London-based, originally philanthropic turned commercial travel firm whose historical origins coincided with the arrival of the Kodak camera in 1888 – thus, of popular (tourist) photography. This article examines the PTA’s changing relationship with tourist photographers, and how this influenced the company’s understanding of what role photography could play in promoting the tours, in the late nineteenth and early twenty century. This inquiry is advanced on the basis of the observation that, during this time, the PTA’s passage from viewing tourists as citizens to educate, to customers to please, paralleled the move from using photography-based images to mixed media. Such a development was certainly a response to unprecedented market demands; this article argues that it should also be considered in relation to the widening of photographic perceptions engendered by the democratization of the medium, to which the PTA responded, first as educator, then as service provider. In doing so, the article raises several questions about the shifting relationship between “high”, or established, and “low”, or emerging, forms of culture, as mass photography and the mass marketing of tourism developed.

An accessibility planning tool for network transit oriented development : SNAP

In the academic debate regarding the influences between urban form, built environment and travel patterns, a specific idea that has taken hold is that more compact urban development around railway stations, often referred to as Transit Oriented Development (TOD), contributes to the control of vehicle travel and to more sustainable metropolitan systems. According to this general principle this work proposes a GIS accessibility tool for the design of polycentric transit oriented scenario: SNAP - Station Network Accessibility Planning tool. In the first part the state of the art on Transit Oriented Development policies in Europe is presented with a focus on three study cases. In the second part the SNAP tool is described, with remarks to the approach, the methodology and the used indicators. Furthermore the paper discusses an application to the metropolitan area of Naples.

A Travel Optimization System for Academic Environments

Carpooling initiated in America in the 1970s due to the oil crisis. However, over the past years, carpooling has increased significantly across the world. Some countries have created a High Occupancy Vehicle (HOV) lane to encourage commuters not to travel alone. In additional, carpool websites has been developed to facilitate the connection between the commuters, making it possible to create a compatible match in a faster and efficient manner. This project focuses on carpooling, especially in an academic environment since younger people are more likely to choose carpool. Initially, an intense research was made to examine carpool studies that occurred all over the world, following with a research of higher education institutes that use carpooling as a transportation mode. Most websites created carpools by targeting people from a specific country. These commuters have different origins and destinations making it more complicated to create compatible matches. The objective of this project is to develop a system helping teachers and students from an academic environment to create carpool matches. This objective makes it easier to create carpools because these students and teachers have the same destination. During the research, it was essential to explore, as many as possible, existing carpool websites that are available across the world. After this analysis, several sketches were made to develop the layout and structure of the web application that’s being implemented throughout the project. Once the layout was established, the development of the web application was initiated. This project had its ups and downs but it accomplished all the necessary requirements. This project can be accessed on the link: http://ipcacarpool.somee.com. Once the website was up and running, a web-based survey was developed to study the reasons that motivate people to consider carpooling as an alternative to driving alone. To develop this survey was used a tool called Survey Planet. This survey contained 408 respondents, which 391 are students and 17 are teachers. This study concludes that a majority of the respondents don’t carpool, however they will consider carpooling if there was a dedicated parking space. A majority of the respondents that carpool initiated less than a year ago, indicating that this mean of transportation is recent.

Telling stories of culture through literature

Grounded on Raymond Williams‘s definition of knowable community as a cultural tool to analyse literary texts, the essay reads the texts D.H.Lawrence wrote while travelling in the Mediterranean (Twilight in Italy, Sea and Sardinia and Etruscan Places) as knowable communities, bringing to the discussion the wide importance of literature not only as an object for aesthetic or textual readings, but also as a signifying practice which tells stories of culture. Departing from some considerations regarding the historical development of the relationship between literature and culture, the essay analyses the ways D. H. Lawrence constructed maps of meaning, where the readers, in a dynamic relation with the texts, apprehend experiences, structures and feelings; putting into perspective Williams‘s theory of culture as a whole way of life, it also analyses the ways the author communicates and organizes these experiences, creating a space of communication and operating at different levels of reality: on the one hand, the reality of the whole way of Italian life, and, on the other hand, the reality of the reader who aspires to make sense and to create an interpretative context where all the information is put, and, also, the reality of the writer in the poetic act of writing. To read these travel writings as knowable communities is to understand them as a form that invents a community with no other existence but that of the literary text. The cultural construction we find in these texts is the result of the selection, and interpretation done by D.H.Lawrence, as well as the product of the author‘s enunciative positions, and of his epistemological and ontological filigrees of existence, structured by the conditions of possibility. In the rearticulation of the text, of the writer and of the reader, in a dynamic and shared process of discursive alliances, we understand that Lawrence tells stories of the Mediterranean through his literary art.

Direct electroanalytical determination of fluvastatin in a pharmaceutical dosage form: batch and flow analysis

The reduction of luvastatin (FLV) at a hanging mercury-drop electrode (HMDE) was studied by square-wave adsorptive-stripping voltammetry (SWAdSV). FLV can be accumulated and reduced at the electrode, with a maximum peak current intensity at a potential of approximately 1.26V vs. AgCl=Ag, in an aqueous electrolyte solution of pH 5.25. The method shows linearity between peak current intensity and FLV concentration between 1.0 10 8 and 2.7 10 6 mol L 1. Limits of detection (LOD) and quantification (LOQ) were found to be 9.9 10 9 mol L 1 and 3.3 10 8 mol L 1, respectively. Furthermore, FLV oxidation at a glassy carbon electrode surface was used for its hydrodynamic monitoring by amperometric detection in a flow-injection system. The amperometric signal was linear with FLV concentration over the range 1.0 10 6 to 1.0 10 5 mol L 1, with an LOD of 2.4 10 7 mol L 1 and an LOQ of 8.0 10 7 mol L 1. A sample rate of 50 injections per hour was achieved. Both methods were validated and showed to be precise and accurate, being satisfactorily applied to the determination of FLV in a commercial pharmaceutical.

BIWiki - Using a Business Intelligence Wiki to Form a Virtual Community of Practice for Portuguese Master's Students

Web 2.0 software in general and wikis in particular have been receiving growing attention as they constitute new and powerful tools, capable of supporting information sharing, creation of knowledge and a wide range of collaborative processes and learning activities. This paper introduces briefly some of the new opportunities made possible by Web 2.0 or the social Internet, focusing on those offered by the use of wikis as learning spaces. A wiki allows documents to be created, edited and shared on a group basis; it has a very easy and efficient markup language, using a simple Web browser. One of the most important characteristics of wiki technology is the ease with which pages are created and edited. The facility for wiki content to be edited by its users means that its pages and structure form a dynamic entity, in permanent evolution, where users can insert new ideas, supplement previously existing information and correct errors and typos in a document at any time, up to the agreed final version. This paper explores wikis as a collaborative learning and knowledge-building space and its potential for supporting Virtual Communities of Practice (VCoPs). In the academic years (2007/8 and 2008/9), students of the Business Intelligence module at the Master's programme of studies on Knowledge Management and Business Intelligence at Instituto Superior de Estatistica e Gestao de Informacao of the Universidade Nova de Lisboa, Portugal, have been actively involved in the creation of BIWiki - a wiki for Business Intelligence in the Portuguese language. Based on usage patterns and feedback from students participating in this experience, some conclusions are drawn regarding the potential of this technology to support the emergence of VCoPs; some provisional suggestions will be made regarding the use of wikis to support information sharing, knowledge creation and transfer and collaborative learning in Higher Education.

Melhoria e automação de linhas de montagem

Hoje em dia, e com os avanços tecnológicos a surgirem de forma constante, existem novas áreas que têm de ser consideradas com um foco importante por parte de todas as organizações, sendo uma delas a robótica industrial. Motivada em aumentar o seu output, as condições de trabalho para os seus colaboradores, bem como todas as condições de organização da logística interna, a Grohe Portugal, mais especificamente o departamento da montagem, achou relevante fazer um estudo de métodos e tempos, calculando os ganhos potenciais de aumento de output com introdução de robótica nas linhas dos cartuchos. Os objetivos principais seriam então, fazer uma restruturação de todo o layout dessas linhas, tendo como foco automatizar alguma(s) operação(ões), conseguindo assim uma melhoria significativa do output dessas linhas com o menor payback possível. Posto isto, esta dissertação pretende apresentar o trabalho desenvolvido junto da Grohe Portugal, que teve como objetivo fazer os estudos e a automatização de linhas de montagem de cartuchos, bem como melhorar algumas linhas de montagem tendo em conta fatores ergonómicos. Relativamente à automatização da linha dos cartuchos, foi importante estudar todos os seguintes aspetos:  utilização de unidades robóticas;  ergonomia;  ganhos de produtividade;  automatizar ou semi-automatizar operações;  simplificar processos de montagem;  simplificar setups;  solicitar orçamentos;  elaborar caderno de encargos. Para a realização deste projeto, o trabalho desenvolvido foi decomposto em várias etapas, entre as quais se destacam:  análise e estudo dos métodos e sequências de montagem;  levantamento de todos os componentes e operações de montagem até à obtenção do cartucho final;  estudo de tempos de todas essas operações de montagem;  caraterização de um novo layout para as linhas com a introdução de unidades robóticas, tanto quanto possível, mais adequadas;  elaboração de caderno de encargos para ser enviado a empresas, para estas poderem apresentar uma orçamentação, bem como indicar as unidades robóticas mais adequadas para as tarefas pretendidas;  automatização da linha dos cartuchos. Relativamente ao projeto de novas linhas de montagem tendo em conta fatores ergonómicos, de forma a melhorar os sistemas de abastecimento e as condições de trabalho por parte dos operadores, foram postos em prática diferentes passos, nomeadamente:  identificação de todos os processos de montagem realizados pelos operadores na linha a melhorar;  estudo e definição da disposição dos componentes na nova linha, bem como a sua forma de abastecimento;  projeto da nova linha de montagem em 3D com recurso ao software SolidWorks;  realização prática da linha, acompanhando e ajudando a equipa da ferramentaria. O balanço final do trabalho foi bastante positivo, tanto na automatização das linhas de montagem dos cartuchos, em que todo o seu estudo foi alcançado com sucesso, como no melhoramento ergonómico das linhas de montagem, tendo-se alcançado melhorias em alguns índices de qualidade, tempos de abastecimento, organização das linhas, e nas condições de iluminação, resultando essas melhorias numa avaliação positiva por parte dos colaboradores que nelas trabalham todos os dias.

Orientalism and Imperialism in French West Africa. Considerations on travel literature, colonial tourism, and the desert as a “commodity” in Mauritania

In this article we intend to make a summary overview of the influence that literary production, originated under colonial mapping missions or later in travel writing, had in the construction and establishment of a discourse to advertise and promote tourism in Mauritania. To this end we will draw on travel narratives that are illustrative of different periods and that correspond in some way to discourses of otherness. In this specific case, such discourses relate to the “Moors” of the West African coast and were produced in various historical contexts. We will also consider the discourse present in the tourism promotion materials of the colonial period and we will demonstrate to what extent it can be engaged in a dialogue with 19th and 20th centuries’ Western colonial literature.

Of Structural Denial: A Narratological Study of the Structural Disintegration of the Novel Form

If an opening to the argument of this dissertation is of imperative necessity, one might tentatively begin with Herbert Quain, born in Roscommon, Ireland, author of the novels The God of the Labyrinth (1933) and April March (1936), the short-story collection Statements (1939), and the play The Secret Mirror (undated). To a certain extent, this idiosyncratic Irish author, who hailed from the ancient province of Connacht, may be regarded as a forerunner of the type of novels which will be considered in this dissertation. Quain was, after all, the unconscious creator of one of the first structurally disintegrated novels in the history of western literature, April March. His first novel, The God of the Labyrinth, also exhibits elements which are characteristic of structurally disintegrated fiction, for it provides the reader with two possible solutions to a mysterious crime. As a matter of fact, one might suggest that Quain’s debut novel offers the reader the possibility to ignore the solution to the crime and carry on living his or her readerly life, turning a blind eye to the novel itself. It may hence be argued that Quain’s first novel is in fact a compound of three different novels. It is self-evident that the structure of Quain’s oeuvre is of an experimental nature, combining geometrical precision with authorial innovation, and one finds in it a higher consideration for formal defiance than for the text itself. In other words, the means of expression are the concern of the author and not, interestingly, the textual content. April March, for example, is a novel which regresses back into itself, its first chapter focussing on an evening which is preceded by three possible evenings which, in turn, are each preceded by three other, dissimilar, possible evenings. It is a novel of backward-movement, and it is due to this process of branching regression that April March contains within itself at least nine possible novels. Structure, therefore, paradoxically controls the text, for it allows the text to expand or contract under its formal limitations. In other words, the formal aspects of the novel, usually associated with the restrictive device of a superior design, contribute to a liberation of the novel’s discourse. It is paradoxical only in the sense that the idea of structure necessarily entails the fixation of a narrative skeleton that determines how plot and discourse interact, something which Quain flouts for the purposes of innovation. In this sense, April March’s convoluted structure allows for multiple readings and interpretations of the same text, consciously germinating narratives within itself, producing different texts from a single, unique source. Thus, text and means of expression are bonded by a structural design that, rather than limiting, liberates the text of the novel.

Surrogacy in Portugal

Surrogacy is the arrangement made by at least three people, in order for a surrogate or gestational mother to carry a pregnancy for the two intended parents, with the objective of the former party relinquishing all rights to the child, once the child is born. As it has only been in recent years that that same reproductive method has begun to be commonly accepted due to certain modern scientific developments that thus diminished ethical and moral negative stances, there is still an unsettling legal void (both at a national and international level) in regards to such subsidiary form of reproduction. As such, some countries have not only left their citizens with no choice but to travel abroad in order to enter a surrogacy arrangement (leading to private international law issues on establishing parenthood and nationality of the born child) or to resort to surrogacy within black market conditions. Unfortunately, one of those countries is Portugal as it has been considered, both by its political parties and experts in the area, and by its citizens as not dealing adequately with such theme and thus being poorly equipped to deal with surrogacy, at both a legal and social level. The present paper attempts to analyse Portugal’s current legal perspective by looking at the present efforts being made to contradict the current situation, and thus outline altruistic gestational surrogacy’s tangible future within such nation. In order to also become aware of possible improvements specifically regarding to the full protection of human rights and human dignity as a whole, the United Kingdom’s legal standpoint in relation to surrogacy was also studied. Via direct comparison of both social and legal perspectives, a new approach to altruistic surrogacy is thus proposed with view to suggest a harmonious solution for countries that have at least recognized that the present issue deserves to be duly noticed and that altruistic gestational surrogacy may exist in order to grant protection of human dignity and not to place it in check.
