Homogenization of Portuguese long-term temperature data series: Lisbon, Coimbra and Porto

Three long-term temperature data series measured in Portugal were studied to detect and correct non-climatic homogeneity breaks and are now available for future studies of climate variability. Series of monthly minimum (Tmin) and maximum (Tmax) temperatures measured in the three Portuguese meteorological stations of Lisbon (from 1856 to 2008), Coimbra (from 1865 to 2005) and Porto (from 1888 to 2001) were studied to detect and correct non-climatic homogeneity breaks. These series together with monthly series of average temperature (Taver) and temperature range (DTR) derived from them were tested in order to detect homogeneity breaks, using, firstly, metadata, secondly, a visual analysis and, thirdly, four widely used homogeneity tests: von Neumann ratio test, Buishand test, standard normal homogeneity test and Pettitt test. The homogeneity tests were used in absolute (using temperature series themselves) and relative (using sea-surface temperature anomalies series obtained from HadISST2 close to the Portuguese coast or already corrected temperature series as reference series) modes. We considered the Tmin, Tmax and DTR series as most informative for the detection of homogeneity breaks due to the fact that Tmin and Tmax could respond differently to changes in position of a thermometer or other changes in the instrument's environment; Taver series have been used, mainly, as control. The homogeneity tests show strong inhomogeneity of the original data series, which could have both internal climatic and non-climatic origins. Homogeneity breaks which have been identified by the last three mentioned homogeneity tests were compared with available metadata containing data, such as instrument changes, changes in station location and environment, observing procedures, etc. Significant homogeneity breaks (significance 95% or more) that coincide with known dates of instrumental changes have been corrected using standard procedures. It was also noted that some significant homogeneity breaks, which could not be connected to the known dates of any changes in the park of instruments or stations location and environment, could be caused by large volcanic eruptions. The corrected series were again tested for homogeneity: the corrected series were considered free of non-climatic breaks when the tests of most of monthly series showed no significant (significance 95% or more) homogeneity breaks that coincide with dates of known instrument changes. Corrected series are now available in the frame of ERA-CLIM FP7 project for future studies of climate variability.

On Becoming a Working Visual Artist: Opportunities and Challenges Along the Path

Thousands of students graduate from colleges and art schools every year with the goal of becoming working visual artists. The majority of them, however, find that earning a living as a working artist is a tough and competitive career path. This Capstone Project, through an extensive literature review and interviews, examines the factors and characteristics that influence whether an individual will make the leap to becoming a working visual artist. Research results indicate that primary factors in achieving the status of working visual artists include specific personality traits, experiential and career-oriented arts education, and development of strong business skills.

Time course modifications in organotypic culture of human neuroretina

The purpose of this study was to characterize organ culture of human neuroretina and to establish survival and early degeneration patterns of neural and glial cells. Sixteen neuroretina explants were prepared from 2 postmortem eyes of 2 individuals. Four explants were used as fresh retina controls, and 12 were evaluated at 3, 6, and 9 days of culture. Neuroretina explants (5 × 5 mm) were cultured in Transwell® dishes with the photoreceptor layer facing the supporting membrane. Culture medium (Neurobasal A-based) was maintained in contact with the membrane beneath the explant. Cryostat and ultrathin sections were prepared for immunohistochemistry and electron microscopy. Neuroretinal modifications were evaluated after toluidine blue staining and after immunostaining for neuronal and glial cell markers. Ultrastructural changes were analyzed by electron microscopy. From 0 to 9 days in culture, there was progressive retinal degeneration, including early pyknosis of photoreceptor nuclei, cellular vacuolization in the ganglion cell layer, decrease of both plexiform layer thicknesses, disruption and truncation of photoreceptor outer segments (OS), and marked reduction in the number of nuclei at both nuclear layers where the cells were less densely packed. At 3 days there was swelling of cone OS with impairment of pedicles, loss of axons and dendrites of horizontal and rod bipolar cells that stained for calbindin (CB) and protein kinase C (PKC-α), respectively. After 9 days, horizontal cells were pyknotic and without terminal tips. There were similar degenerative processes in the outer plexiform layer for rod bipolar cells and loss of axon terminal lateral varicosities in the inner plexiform layer. Glial fibrillary acidic protein (GFAP) staining did not reveal a dramatic increase of gliosis in Müller cells. However, some Müller cells were CB immunoreactive at 6 days of culture. Over 9 days of culture, human neuroretina explants underwent morphological changes in photoreceptors, particularly the OS and axon terminals, and in postsynaptic horizontal and bipolar cells. These early changes, not previously described in cultured human samples, reproduce some celullar modifications after retinal damage. Thus, this model may be suitable to evaluate therapeutic agents during retinal degeneration processes.

La réception de la culture russe par les Français et les Espagnols: analyse sémiotique, linguistique et socioculturelle

El trabajo trata diferentes caminos que pueden llevar a lo esencial de la cultura rusa: lengua y léxico; semiótica visual, fotos y códigos arquitecturales; factores externos a la lengua; comportamiento comunicativo de los individuos. Se pretende demostrar que esta aprensión de la cultura meta es más eficaz y verosímil que su recepción en base a un inventario de heteroestereotipos.

Equestrian tourism: an opportunity for portuguese

Portugal provides a large number of factors that boost the development of the national equestrian tourism. It represents an opportunity for the qualification and differentiation of the national tourism, to stimulate rural economies, to combat seasonality and asymmetries.This study want to understand the importance, for the equestrian tourist, of the critical success factors such as the Lusitano horse, the national equestrian culture, the landscape diversity, among others. Also, how they can contribute to the differentiation of the national equestrian tourism for international destinations that are already deployed in the market.For this study is crucial to know the perspective of those involved in the various equestrian tourism activities. In this sense, a group of companies were selected and exploratory interviews were conducted that contributed to important outputs in the construction of the questionnaire.The research was attended by 110 individuals, with different profiles, motivations and types of involvement. From the analysis, it is concluded that the critical success factors are significant in motivating equestrian tourists, namely the quality of equestrian infrastructures, the Lusitano horse, the hospitality, among others. It is also possible to analyze that the equestrian tourist demonstrates a strong commitment: they are knowledgeable, read a lot about riding and belong to equestrian clubs.Finally, the factor analysis highlight the agreement between participants and a significant number of statements made in the questionnaire related to motivation and involvement. It is possible to conclude that equestrian tourists look for relaxing moments and opportunities to expand their equestrian knowledge.

Albanian Sworn Virgins: A Visual Representation of their Transformation

This piece of art is a flipbook, analogous to the ones children play with as they make cartoon balls bounce with the quick flipping of pages between their thumb and index finger. However, instead of a playful scene, this flipbook is a commentary on Albanian Sworn Virgins. These are women from Northern Albania who, in their youth, swear to celibacy in order to gain the societal power that is exclusive to men in their culture. This flipbook demonstrates this cultural male-to-female shift and comments on its inability to ever be fully realized. This commentary is inspired by the words of Albanian Sworn Virgins in Elvira Dones’ documentary, Sworn Virgins, who feel betrayed by their biological need to menstruate and who view their reproductive system as a permanent obstacle in completing their societal shift. Just as a child’s flipbook tells a story, this flipbook illustrates the Albanian Sworn Virgins’ forever-unfinished transformation.

(Para)translated ideologies in Simone de Beauvoir's 'Le deuxième sexe': the (para)translator's role

At the beginning of the 80s new approaches to translation were emerging in such a way that, in the global context of postmodernism and poststructuralism, they provoked a reassessment of Translation Studies (TS), acknowledging ideologies as a relevant concept to TS and considering the political and visible role of the translator. This introduction aims to establish a basic theoretical framework in which we can develop an analysis of the ‘alterations’ that, consciously or unconsciously, translators have imposed on Le deuxième sexe (1949, Gallimard) by Simone de Beauvoir for the last fifty years. Furthermore, it is essential to examine the divergences of the censoring attitude adopted by the first male translators (Parshley, Palant and Milliet) who considered this text to be a sex manual, and the one adopted by more recent female translators (Martorell and Simons) who considered it to be a philosophical book on feminism. Nevertheless, despite this tendency to consider that translators are the only professionals responsible for the translation process, it is necessary to bear in mind the work carried out by the paratranslator, who is the real censor and ‘decider’ of the way a work is presented to the translation community. Paratranslators work with paratexts (also known as ‘analysis-spaces’), and this makes it possible to study the ideological adaptation that a cultural object undergoes when it is incorporated into a new culture and society (covers, volumes, tables of contents, titles, iconic or visual elements and so forth). In short, the analysis of the texts and paratexts of Le deuxième sexe, along with its subsequent translations and rewritings into Spanish, Portuguese and English, will help reveal the function of the censoring apparatus and demonstrate the essential role that –without exception– ideologies play in the professional work of translation and paratranslation, since they have a decisive influence on the reception of the cultural (and ideological) object, in both the society in which it is created and that in which it is received.

Sanctioning pregnancy:a psychological perspective on the paradoxes and culture of research

Pregnancy provides a very public, visual confirmation of femininity. It is a time of rapid physical and psychological adjustment for women and is surrounded by stereotyping, taboos and social expectations. This book seeks to examine these popular attitudes towards pregnancy and to consider how they influence women’s experiences of being pregnant. Sanctioning Pregnancy offers a unique critique of sociocultural constructions of pregnancy and the ways in which it is represented in contemporary culture, and examines the common myths which exist about diet, exercise and work in pregnancy, alongside notions of risk and media portrayals of pregnant women. Topics covered include: •Do pregnant women change their diet and why? •Is memory really impaired in pregnancy? •How risky behaviour is defined from exercise to employment •The biomedical domination of pregnancy research. Different theoretical standpoints are critically examined, including a medico-scientific model, feminist perspectives and bio-psychosocial and psychodynamic approaches. Table of Contents: Introduction. Cognition and Cognitive Dysfunction. Working and Employment. Dietary Change and Eating. Exercise and Activity. Pregnancy and Risk. Pregnancy Under Surveillance. Concluding Remarks. References/Bibliography. Index.

Changing visual value of deciduous species in the climate change

The article deals with the changing visual value of deciduous species. Due to climate change, the climatic patterns found on the plants’ growing area may change. Therefore, foliage of deciduous trees changes itscolor in the fall season witha different timing and intensity. This shift can modify the functional, ornamental and ecological value of these plants in the fall season, which is of special interest in the context of landscape design. However, this effect of climate change hasn’t been examined in terms of landscape architecture yet.In the article we are looking for deciduous species that can be appropriate subjectsforresearch, we are giving suggestions for choosing the right location for a future research and proposing available resources of satellite images, that can provide the basis for evaluation of leaf coloring. We also review already existing methods for calculating the degree of fall leaf coloring.We propose a novel method of satellite image processing to evaluate the coloring of a stand. Leaf Coloring Index (LCI) shows the leaf color’s relation to the color realms. LCI is appropriate for setting up a phenological model based onclimate data in a future research. Based on future climate models, the change of the examined stand’s visual value can be predicted. The results might affect the future use of plant species in landscape architecture.

The 1992 BFA Graduating Class, Department of Visual Arts

Before writing this introductory piece, I spent some time viewing the Fourth Year Student Exhibition. It was a time-out in a busy adminstrative morning,and an important occasion for reflecting upon the visual arts program at Sir wilfred Grenfell College. The works in the gallery, some of which are reproduced on the following pages, are as varied as the individuals who made them. Yet the paintings, prints,sculptures and photographs provides a glimpse into the richness of the experienceof the past years for these students. The mix of techniques, colors, images and line suggest the breadth of experience and knowledge shared with these students by their professors. The Quality and force of the works signal the future contributions these graduates will make to our society and culture.

Arcabouço jurídico normativo pedagógico da lei federal 10.639/2003 na universidade federal de Uberlândia: avanços e limites

This search addresses the public policies that directly or indirectly corroborate for the implementation of the Brazilian Law number 10.639/2003 in Federal University of Uberlândia and it analyzes the affirmative actions in this context. The study aims to answer some questions such as: Why we have found difficulties in implementing the Law 10.639/2003 and its correlate legislation in the institutions responsible for teachers formation, particularly in the courses of History, Visual Arts, Portuguese Language and Literature and Education teachers? We started from the hypothesis that implementing the Law 10.639/2003 is considered by popular movements that fight for the emancipation of black population and for its rights consider such actions as a form of eradicating racial and ethnic prejudice which are still present in our society. The methodology is based on case study, which allows the triangulation to other methodological approaches such as qualitative analysis and bibliographic search. The investigation instruments were: I. Bibliographic sources including books, papers, periodic and so one; II. Documental sources: specific legislation on the theme (Brazilian Federal Law 10.639/2003, Resolution CNE/CP 1/2004 and others; III. Oral sources obtained from semi structured interviews with coordinators of the selected Graduation courses. Critical multicuturalism according to McLaren (1999) allowed us to approach our research object in order to understand its plural characteristics, specially reading the different aspects that permeate the relationship between culture and identity, cultural differences and power relationship in modern society. In the study, we did not perceive the involvement of the Higher Education professionals in order to implement Law 10.639/2003. The problem perceived for implementing the law and its pedagogical normative legal framework is the personal and institutional attitude, because every subject involved in it has a direct responsibility. We cannot believe that the institutions may claim lack of knowledge and research in the area as impediments to implementing the disciplines and the pedagogical contents concerning to the Law nor contracting researcher experts and scholars on this topic to compose the frames of the University.

Etnografia visual das mangabeiras nas matas do tabuleiro costeiro.

This work is an ethnographic research with collectors women of Mangaba in the village of Ponta Negra in Natal - RN. This Women also known as Mangabeira's women reproduce a practice learned with their ancestors, collecting this fruit in the coastal tablelands forests and latter commercializing it in the local markets. This research uses the methodology of oral history and visual anthropology with presentation of collected images on board. It is intended to emphasize the botanical and environmental aspects of the Mangabeira plant, its ecosystem, territorial, economic and historical aspects of it, also the knowledge of this extractive practice of our immaterial culture.
