- De l’objet intrinsèque à la pensée technique: le rôle médiateur du dessin en ethnographie maritimePublication . Escallier, ChristineL’image – fixe, en mouvement ou virtuelle – est devenue un moyen de communi cation et de représentation qui s’impose dans tous les domaines, aussi bien scienti fiques qu’artistiques. Sa permanente évolution technique pourrait paraître frap per d’obsolescence des formes traditionnellement mobilisées par l’ethnographie, comme le dessin. L’image graphique reste pourtant un outil fondamental pour les ethnologues-anthropologues. Cet article s’interroge sur la place et la force du des sin ethnographique dans le rendu des données issues de l’enquête de terrain et qui s’impose au cours de la recherche. Peut-il supplanter le discours, dépasser les mots, ou collaborer avec d’autres formes représentatives dont le but initial est de rendre l’objet présent ? Et qu’en est-il du dessin fait par l’informateur lui-même, à la demande de l’observateur, et de son interprétation ? C’est dans le cadre d’une anthropologie des techniques et maritime que l’auteur situe cette problématique particulière en s’appuyant sur une méthode utilisée sur son terrain – la commu nauté de pêcheur de Nazaré, au Portugal – où l´étude graphique domine. Cette expérience permet de mettre en évidence le rôle et les apports spécifiques de ces techniques de description et d’analyse, démontrant ainsi que l’image plastique – autrement dit la photographie et le film – ne peut être exclue des pratiques de mémorisation de l’objet dans l’histoire des sciences humaines.
- Maria Lamas: o despertar da mulher num percurso da escrita epistolar para a escrita públicaPublication . Falcão, Ana Margarida; Moniz, Ana IsabelPretende-se, neste ensaio, apresentar correspondência inédita de Maria Lamas, directora da revista feminina “Modas & Bordados”, que permite demonstrar a abertura de oportunidades que a jornalista conferia às jovens mulheres escritoras suas contemporâneas. Neste sentido, far-se-á referência à breve história de como uma das jovens colaboradoras da referida revista se tornou amiga de Maria Lamas, trocando correspondência da qual iremos apresentar uma carta inédita enviada à dita amiga, em Janeiro de 1962, aquando da prisão de seu irmão, Vassalo e Silva, último governador do Estado Português da Índia. São ainda apresentados exemplos de textos de dois números da “Revista Modas & Bordados”, de Março de 1943, através dos quais Maria Lamas publica, de modo subtil, temas susceptíveis de serem cortados pela Comissão de Censura política da época, Este “modus operandi” revela a coragem e audácia da contribuição de Maria Lamas, como directora da Revista “Modas & Bordados”, para a alteração de paradigmas do papel da mulher e da sua intervenção na sociedade dos anos quarenta.
- De l’intention photographique à l’image, miroir des sciencesPublication . Escallier, ChristineL’image est le miroir des sciences qui cherchent à comprendre l’Homme, ses comportements, ses caractères, ses pensées. Elle facilite l’étude du vocabulaire de la communication non-verbale qu’est le langage du corps. C’est pourquoi la photographie, bien plus ancienne que le cinéma, a révolutionné tant les sciences naturelles, humaines et sociales que les arts. Elle a joué un rôle essentiel auprès des scientifiques – ethnologues, criminologues, psychologues ou encore médecins – dans leurs recherches, permettant une approche plus directe sur la complexité de la représentation de l’Autre. Le photographe, le cinéaste et l’anthropologue ont en commun le fait d’observer et de s’approprier par l’image l’être humain. Ils sont des capteurs d’instants et d’histoires. Ce regard porté sur autrui suppose objectivité et distance mais également interrogation sur soi-même.
- Currículo em tempo de mestiçagemPublication . Sousa, Jesus MariaQuer chamemos de observação do meio, análise da realidade, ou levantamento de necessidades, em qualquer planeamento curricular existe sempre uma etapa prévia, que é o da reflexão sobre o mundo que nos rodeia, enquanto unidade espaço tempo onde se desenrolará uma prática pedagógica intencionalmente organizada. E que espaço-tempo é o nosso? Esta reflexão pretende alertar para o desfasamento cada vez mais evidente entre o currículo que se mantém monorreferencialmente petrificado, fiel às suas origens científicas e tecnológicas, e o tempo que vivemos de mestiçagem ético-filosófica, política e ideológica.
- Seasonal and interannual variations in coccolithophore abundance off Terceira Island, Azores (Central North Atlantic)Publication . Narciso, Áurea; Gallo, Francesca; Valente, André; Cachão, Mário; Cros, Lluïsa; Azevedo, Eduardo B.; Ramos, Joana BarcelosIn order to characterize the natural coccolithophore community occurring offshore Azores and to de-termine their annual and interannual patterns, monthly samples were collected, from September 2010 toDecember 2014, in the photic zone off Terceira Island.The present study revealed a clear seasonal distribution and a considerable interannual variability of theliving coccolithophore community. The highest coccolithophore abundances were observed during spring andwinter months, especially due to the smaller speciesEmiliania huxleyiandGephyrocapsa ericsonii. In fact, thehighest biomass period was registered during April 2011, associated with enhanced abundance of the over-calcified morphotype ofE. huxleyi,whichwaspossiblyinfluenced by subpolar waters and subsequent up-welling conditions. The highest abundances ofGephyrocapsa muelleraewere recorded during June 2011 and2014, indicating that this species characterizes the transition between the period of maximum productivity andthe subsequent smoother environmental conditions, thefirst and the later stages of the phytoplankton suc-cession described by Margalef, respectively. During summer to early fall, a gradual decrease of the overallcoccolithophore abundance was observed, while the species richness (Margalef diversity index) increased. Asubtropical coccolithophoreassemblage mainly composed byUmbellosphaera tenuis,Syracosphaeraspp.,Dis-cosphaera tubifera,Rhabdosphaera clavigeraandCoronosphaera mediterraneaindicated the presence of surfacewarmer waters accompanied by reduced mixing and low nutrients concentration. During late fall to winter, thecoccolithophore abundance increased again with a concomitant reduction in species diversity. This is poten-tially linked to low sea surface temperatures, moderate nutrients concentration and surface mixed layerdeepening. During 2011, colder and productive waters led to an increase in the total coccolithophore abun-dances. On contrary, during 2012, characterized by milder environmental conditions, an increase in the di-versity of the community was prevalent. The noticeably coccolithophore response to variations in the mainphysical variables and on main traditional nutrients corroborates the importance of this group as proxy ofmarine environmental conditions in the past.&2016 Elsevier Ltd.

IntroductionCoccolithophores are pelagic unicellular algae, members of thehaptophyte class Prymnesiophyceae Hibberd, distinguished by theability to produce calcite platelets called coccoliths, which surroundthe living cell and form an exoskeleton called coccosphere (e.g. Winterand Siesser, 1994; Young, 1994). Coccolithophores, known since thelate Jurassic (Hay, 2004), have an ocean wide distribution and re-present the most productive calcifying organisms on Earth (Honjo,1996). They also affect the ocean-atmosphere carbon dioxide exchangeand produce dimethyl sulfide (DMS), which stimulates cloud forma-tion, thus actively participating in the climate system (Berger et al.,1989;Westbroek et al., 1993;Rost and Riebesell, 2004). Since thiscalcifying group has potential to fossilize as calcareous nannoplankton,it becomes a (paleo)environmental proxy directly dependent ontemperature, salinity, and nutrients and light availability (e.g.,McIntyreand Bé, 1967;Giraudeau et al., 1993; Winter and Siesser, 1994).Coccolithophores usually dominate the phytoplankton biodiversity inthe oligotrophic central gyres of the oceans (e.g. McIntyre and Bé, 1967;Winter et al., 1994;Ziveri et al., 2004), being also markedly present attemperate (e.g.Giraudeau and Bailey, 1995;Cachão et al., 2000) and highlatitude eutrophic regimes (e.g.Andruleit, 1997;Baumann et al., 2000).Although the geographic distribution of coccolithophores hasbeen well studied over the last four decades, its seasonal dynamicsContents lists available atScienceDirectjournal homepage:www.elsevier.com/locate/csrContinental Shelf Researchhttp://dx.doi.org/10.1016/j.csr.2016.01.0190278-4343/&2016 Elsevier Ltd.

- Gene delivery using dendrimer/pDNA complexes immobilized in electrospun fibers using the Layer-by-Layer techniquePublication . Ramalingam, Kirthiga; Castro, Rita; Pires, Pedro; Shi, Xiangyang; Rodrigues, João; Xiao, Shili; Tomás, HelenaA gene delivery platform for potential use in tissue engineering applications was developed by surface functionalization of biodegradable electrospun poly(lactic-co-glycolic acid) (PLGA) fibers with nanolayers of chitosan (cationic polymer) and alginate (anionic polymer) using the Layer-by-Layer (LbL) technique. The developed system not only supported the attachment and growth of human Mesenchymal Stem Cells (hMSCs), but also was capable of delivering pDNA/dendrimer complexes and inducing cell differentiation towards the osteogenic lineage when a pDNA codifying for human Bone Morphogenetic Protein-2 (BMP-2) was used. Beyond providing a means for pDNA/dendrimer complex immobilization, the polyelectrolyte coating conferred sustained release properties to the scaffold that resulted in pDNA protection from degradation. The polyelectrolyte coating, by itself, also contributed to enhance cell differentiation.

- Alternative oxidase gene family in Hypericum perforatum L.: characterization and expression at the post-germinative phasePublication . Velada, Isabel; Cardoso, Hélia G.; Ragonezi, Carla; Nogales, Amaia; Ferreira, Alexandre; Valadas, Vera; Arnholdt-Schmitt, BirgitAlternative oxidase (AOX) protein is located in the inner mitochondrial membrane and is encoded in the nuclear genome being involved in plant response upon a diversity of environmental stresses and also in normal plant growth and development. Here we report the characterization of the AOX gene family of Hypericum perforatum L. Two AOX genes were identified, both with a structure of four exons (HpAOX1, acc. KU674355 and HpAOX2, acc. KU674356). High variability was found at the N-terminal region of the protein coincident with the high variability identified at the mitochondrial transit peptide. In silico analysis of regulatory elements located at intronic regions identified putative sequences coding for miRNA precursors and trace elements of a transposon. Simple sequence repeats were also identified. Additionally, the mRNA levels for the HpAOX1 and HpAOX2, along with the ones for the HpGAPA (glyceraldehyde-3-phosphate dehydrogenase A subunit) and the HpCAT1 (catalase 1), were evaluated during the post-germinative development. Gene expression analysis was performed by RT-qPCR with accurate data normalization, pointing out HpHYP1 (chamba phenolic oxidative coupling protein 1) and HpH2A (histone 2A) as the most suitable reference genes (RGs) according to GeNorm algorithm. The HpAOX2 transcript demonstrated larger stability during the process with a slight down-regulation in its expression. Contrarily, HpAOX1 and HpGAPA (the corresponding protein is homolog to the chloroplast isoform involved in the photosynthetic carbon assimilation in other plant species) transcripts showed a marked increase, with a similar expression pattern between them, during the post-germinative development. On the other hand, the HpCAT1 (the corresponding protein is homolog to the major H2O2-scavenging enzyme in other plant species) transcripts showed an opposite behavior with a down-regulation during the process. In summary, our findings, although preliminary, highlight the importance to investigate in more detail the participation of AOX genes during the post-germinative development in H. perforatum, in order to explore their functional role in optimizing photosynthesis and in the control of reactive oxygen species (ROS) levels during the process.
- Inteligência emocional e engagement em professores do ensino básico e secundário da Ilha da MadeiraPublication . Andrade, Cláudia Alexandra; Santos, Natalie Nóbrega; Franco, GlóriaO construto de inteligência emocional tem sido estudado em várias áreas do desenvolvimento humano, nomeadamente na área da saúde organizacional. No entanto, está ainda muito pouco estudada a sua relação com o engagement, e menos ainda com a saúde dos Professores. O engagement é considerado saudável para o desempenho dos professores e o seu bem-estar, beneficiando não somente o indivíduo, mas também, as organizações para onde trabalha. Este estudo teve precisamente como objetivo compreender a relação entre a inteligência emocional e o engagement. A amostra foi constituída por 250 professores do 2º ciclo (5.º e 6.º ano) (26.4%), 3º ciclo (7.º, 8.º e 9.º ano) (57.2%) e Secundário (10.º, 11.º e 12.º ano) (16.4 %), do género feminino (70.4%) e do masculino (29.6%), da Região Autónoma da Madeira (RAM), Portugal. Utilizámos como instrumentos, o Trait Meta-Mood Scale, o Questionário de Expressividade e o de Regulação Emocional de Berkeley e o Utrech Work Engagement Scale. Nos nossos resultados encontramos que quanto maior a atenção às emoções, clareza de sentimentos e reparação do estado emocional, maior é o vigor, dedicação e a absorção. A idade e o tempo de serviço não se mostraram relevantes para a explicação da relação entre os construtos. Concluiu-se que os professores que conseguem regular as suas emoções envolvem-se mais no trabalho e utilizam todas as suas capacidades físicas, cognitivas e emocionais, enquanto desempenham as suas funções, ultrapassando os obstáculos que se lhes interpõem.
- What public experience may be - on publicity, communication and the expression of lived experiencesPublication . Mateus, Samuel André AlvesThe idea of public experience is often invoked in different social and academic contexts. However, it seldom deserved a reflection that specifically sought to deepen its meaning from the point of view of social life. In this article we contribute to the understanding of the uniqueness of the public form of experience. We believe that one of the best ways through which we can observe the public experience is by the objectification, performance and dramatization of the culture, i.e., the “expression of lived experiences”. There is, in publicity, the possibility of simultaneous allocation of individual and collective experiences, and it is in this sense that we can see how culture influences the shaping of experience itself. Public experience is characterized by the weaving and intertwining of singular experiences that are pluralized and plural lived experiences that are singularized, in a process where individual and society interpenetrate. The relationship between experience and publicity arises from this symbolic communion contained in the systems of thought and action of societies. The decisive role of the principle of publicity to experience consists, according with the hypothesis we wish to put forward, in making available and communicating the social world of symbolic (cultural) activity. Public experience is, then, envisaged as the experience of a common world where both singular and plural definitions of the individual (taken as society) converge through lived experiences and, particularly, through their expression, which can take different symbolic forms.
