Análise polinica de argilas de Lagoa Negra

Palynological analysis of black shales from Lagoa Negra (Cantanhede) shows the presence of Cathaya and Keteleeria, Myrica and Engelhardtia being scarce. Comparison with other localities suggest an Upper Pliocene or Lower Pleistocene age for this association.

"Job : humoriste" : vécu de la professionnalisation de l'humoriste québécois francophone

Cette recherche exploratoire et empirique porte sur le vécu de la professionnalisation de l’humoriste québécois francophone. Les ressources théoriques et scientifiques sur le sujet étant peu nombreuses, la théorie ancrée (The Grounded Theory) de Glaser et Strauss (1967) nous permettra d’utiliser nos données de terrain afin que nous puissions les confronter et établir un canevas théorique sur le métier de l’humoriste. Nous nous sommes aussi penchés sur l’étude du rire de Bergson. Selon lui, le rire peut avoir une fonction sociale et c’est aussi un langage universel qui permet à tout un chacun de se reconnaître et de faire partie d’un tout. Du point de vue méthodologique, nous avons interrogé huit humoristes québécois, sept hommes et une femme, jeunes et moins jeunes, ayant fait, ou pas, l’École nationale de l’humour, mais avec comme particularité commune de gagner leur vie en faisant de l’humour. À la suite de ces entrevues, nous avons décidé d’interroger la Directrice de l’École nationale de l’humour, Louise Richer, car chaque humoriste avait un lien particulier avec cette institution. Les entrevues, de type semi-dirigé, ont été réalisées sous une forme chronologique, reliées à une grille de questions sous le thème de la professionnalisation. Les données ont été recueillies et retranscrites (verbatim) grâce à un enregistrement sonore. Faire de l’humour est une profession non conventionnelle où chaque humoriste est laissé à lui-même, mais où rapidement il se crée une espèce de microcosme autour de lui afin de pouvoir évoluer et agir indépendamment des autres. L’adolescence, l’École nationale de l’humour ainsi que le contexte culturel Québécois seront des éléments incontournables à leur professionnalisation.

Inflammatory reaction to the human bot-fly, Dermatobia hominis, in infested and reinfested mice

Two groups of mice were infested with first stage larvae of the human bot-fly, Dermatobia hominis (Linnaeus Jr) (Diptera: Oestridae). In the first group, skin biopsies were carried out 1, 3, 5, 7, 10 and 18 days after infestation. The second group was also infested but had all the larvae removed 5 days after infestation. The mice in the latter group were reinfested 4 weeks later and skin biopsies were carried out 1, 3, 5, 7, 10 and 18 days after reinfestation. In the first group, an inflammatory reaction began slowly, the neutrophils being the main inflammatory cells, eosinophils being scarce. The reaction progressed with time, developing a necrotic halo around the larvae containing inflammatory cells surrounded by fibroblasts. The inflammation invaded the adjacent tissue. In the second group, the inflammatory reaction was intense on the day immediately after reinfestation, the pattern being changed by the presence of a large number of eosinophils. Activated fibroblasts surrounding the necrotic area around the larvae appeared 3 days after reinfestation in the second group and 7 days after infestation in the first group. The results demonstrated that the previous contact with the antigens elicited the early arrival of eosinophils, probably through the chemotactic factors liberated by mast cells in the anaphylactic reaction.

Estrutura e desenvolvimento dos tricomas secretores em folhas de Piper regnellii (Miq.) C. DC. var. regnellii (Piperaceae)

Nesta espécie ocorrem dois tipos de tricomas secretores: glândula perolada e tricoma saculiforme. Ambos originam-se na protoderme do primórdio foliar e atingem sua maturidade nas folhas jovens presentes no ápice caulinar. A densidade dos dois tipos de tricomas diminui durante a expansão do limbo, sendo raros na folha adulta. As glândulas peroladas são constituídas por uma célula basal e por uma célula apical grande cuja forma varia de semi-globóide a espatulada. A liberação da secreção ocorre após a ruptura da cutícula distendida. Os tricomas saculiformes são constituídos por uma célula basal, 1-2 células colares e uma célula apical cônica, de posição inclinada à superfície foliar. A secreção acumula-se em espaços subcuticulares diminutos, não tendo sido observada ruptura da cutícula.

Morfo-anatomia do eixo vegetativo aéreo de Achyrocline alata (Kunth) DC. (Asteraceae)

Achyrocline alata occurs in a dense and low vegetation in Mato Grosso do Sul State, Brazil and it has been studied under physical-chemical and yield aspects, being scarce anatomical data. The present work has as objective the study of the aerial vegetative axis. Stem is cylindrical and hairy, having five wings, which are arisen from their leaves. The blade shows the presence of uniseriate epidermis, which is covered by the cuticle of variable thickness; and non-glandular and glandular trichomes. The non-glandular trichomes are uniseriate and multicellular and have their apex cell in whip form, while the glandular trichomes are multicellular, uniseriate or biseriate. The mesophyll is dorsiventral with uni-stratified palisade parenchyma in most of the cases and lacunal parenchyma formed by three to four layers of irregular cells. Only one collateral vascular bundle occurs in the midvein. Stem in transversal section is covered by epidermis with trichomes similar to leaves; the cortex is constituted by a discontinuous area of angular collenchyma, which is followed by chlorophyll parenchyma. Vascular cylinder that is delimited by pericycle shows vascular bundles of collateral type. In the secondary structure, the periderm is originated from epidermal and subepidermal tissues. In vascular region, the fascicular cambium differs into secondary xylem and phloem, while interfascicular cambium produces sclerenchymatous tissue.

Consequences of big data on the individual: Interview

The speed with which data has moved from being scarce, expensive and valuable, thus justifying detailed and careful verification and analysis to a situation where the streams of detailed data are almost too large to handle has caused a series of shifts to occur. Legal systems already have severe problems keeping up with, or even in touch with, the rate at which unexpected outcomes flow from information technology. The capacity to harness massive quantities of existing data has driven Big Data applications until recently. Now the data flows in real time are rising swiftly, become more invasive and offer monitoring potential that is eagerly sought by commerce and government alike. The ambiguities as to who own this often quite remarkably intrusive personal data need to be resolved – and rapidly - but are likely to encounter rising resistance from industrial and commercial bodies who see this data flow as ‘theirs’. There have been many changes in ICT that has led to stresses in the resolution of the conflicts between IP exploiters and their customers, but this one is of a different scale due to the wide potential for individual customisation of pricing, identification and the rising commercial value of integrated streams of diverse personal data. A new reconciliation between the parties involved is needed. New business models, and a shift in the current confusions over who owns what data into alignments that are in better accord with the community expectations. After all they are the customers, and the emergence of information monopolies needs to be balanced by appropriate consumer/subject rights. This will be a difficult discussion, but one that is needed to realise the great benefits to all that are clearly available if these issues can be positively resolved. The customers need to make these data flow contestable in some form. These Big data flows are only going to grow and become ever more instructive. A better balance is necessary, For the first time these changes are directly affecting governance of democracies, as the very effective micro targeting tools deployed in recent elections have shown. Yet the data gathered is not available to the subjects. This is not a survivable social model. The Private Data Commons needs our help. Businesses and governments exploit big data without regard for issues of legality, data quality, disparate data meanings, and process quality. This often results in poor decisions, with individuals bearing the greatest risk. The threats harbored by big data extend far beyond the individual, however, and call for new legal structures, business processes, and concepts such as a Private Data Commons. This Web extra is the audio part of a video in which author Marcus Wigan expands on his article "Big Data's Big Unintended Consequences" and discusses how businesses and governments exploit big data without regard for issues of legality, data quality, disparate data meanings, and process quality. This often results in poor decisions, with individuals bearing the greatest risk. The threats harbored by big data extend far beyond the individual, however, and call for new legal structures, business processes, and concepts such as a Private Data Commons.

Being in between: An Ethnographic Study of Opera and Dialogical Identity Construction

The paradoxical co-existence of conflicting logics governs practices in cultural organizations. This requires ‘balancing acts’ between artistic and managerial efforts, which are often subjects to struggle among the organizational members. This ethnographic study aims to go beyond either-or thinking on the paradoxical organizational context by examining how the organizational members of an opera house construct views on their organization in dialogical meaning-making processes. Various professional groups, dozens of upcoming productions, increased international cooperation, and global competition combined with scarce financial resources make opera houses a complex though interesting context for organization studies. In order to provide a deeper knowledge of the internal dynamics of an opera organization this thesis takes an interpretative view to examine the ways organizational members construct and make sense of their organization. How is the opera organization constructed by the organizational members? How do the members draw on different logics when relating to their organization? Or what are the elements that characterize the relational processes of organizational identity construction in an opera organization? The thesis aims to answer these questions by providing a detailed description of the everyday life of an opera organization and a particular focus put on organizational identity construction. The processes of organizational identity construction are approached from a relational point of view. This may involve various relations between multiple positions, different professional groups, other organizations in the cultural field or between past and present understandings of an organization. The study shows that the construction of an opera organization involves not only the two conflicting logics of art and economy, but also the logic of a national institution. The study suggests also that organizational identities are constructed through processes related to the dialogics of positions, work and management practices. The dialogics involve various struggles through which the organizational members find themselves between the different organizational aspects such as visiting ‘stars’ and an ensemble or between ‘Finnishness’ of opera productions and internationalization. In addition, the study argues that a struggle between different elements is a general mode of relation in cultural organizations and therefore an inherent and enduring aspect in the organizational identity construction. However, the space of ‘being in between’ involves both the enabling and constraining elements in the dialogical identity construction in the context of cultural organizations, which present the struggle in a more generative light.

Being There

This 60 minute work looked to challenge traditional expectations of how dancers ‘perform’ and what it means when they are ‘themselves’ onstage. The audience was asked to sit in an ellipse on stage and the dancers were often performing quite close to them. While the audience didn’t move once the work began, the proximity to the dancers allowed them an unusual opportunity to see these dancers deconstructing their own profession and their own world of performance in an intimate environment. This was done for, and with the audience, and for some, it connected them deeply with the performers. For Georg Simmel, an early 20th Century sociologist, ‘the eye of a person discloses his own soul when he seeks to uncover that of another. What occurs in this direct mutual reciprocity is the entire field of human relationships.’ Performer authenticity, while utilised often in film and theatre, is not common in the form of dance. Because of our societal tendency toward the desire for authenticity, and its uncommon usage in dance, an inversion of this convention is one of the many tools that is available to choreographers to form deep connections with their audience and is one that is gaining popularity throughout the world as a form of connection via reality and the immediacy of live performance.

Being ethical : how process drama assists pre-service drama teachers to reflect on professional ethics

This research thesis focuses on the experiences of pre-service drama teachers and considers how process drama may assist them to reflect on key aspects of professional ethics such as mandatory codes or standards, principled moral reasoning, moral character, moral agency, and moral literacy. Research from higher education provides evidence that current pedagogical approaches used to prepare pre –professionals for practice in medicine, engineering, accountancy, business, psychology, counselling, nursing and education, rarely address the more holistic or affective dimensions of professional ethics such as moral character. Process drama, a form of educational drama, is a complex improvisational group experience that invites participants to create and assume roles, and select and manage symbols in order to create a fictional world exploring human experience. Many practitioners claim that process drama offers an aesthetic space to develop a deeper understanding of self and situations, expanding the participant’s consciousness and ways of knowing. However, little research has been conducted into the potential efficacy of process drama in professional ethics education for pre-professionals. This study utilizes practitioner research and case study to explore how process drama may contribute to the development of professional ethics education and pedagogy.
