A Cultura Caiçara do Litoral Norte Paulista mostrada na revista Beach&Co Estereótipos do caiçara das cidades de Caraguatatuba, São Sebastião, Ubatuba e Ilhabela em um veículo regional impresso

Estudo dos estereótipos que a revista regional Beach&Co fez do caiçara - povo nativo que mantém uma cultura relacionada ao mar e a mata nas cidades de Caraguatatuba, São Sebastião, Ubatuba e Ilhabela, no Litoral Norte Paulista. Aplicou-se uma metodologia de caráter híbrido que mesclou os Estudos Culturais com base nas obras de Douglas Kellner, Stuart Hall e Raymond Williams com a Análise de Discurso nas obras de Dominique Maingueneau, Eni Orlandi, Patrick Charaudeau e Audre Alberguine. Também foram resgatados os estudos da Cultura Caiçara feitos por Carlos Diegues, Gioconda Mussolini, Emilio Willems, e por fim redefiniu-se o gênero jornalístico Reportagem e contextualizou-se o Jornalismo Regional de Revista. Posteriormente, analisou-se a primeira década da revista Beach&Co, totalizando 120 edições publicadas de janeiro de 2002 a junho de 2012, no qual foram mostradas as diversas abordagens que a publicação fez do caiçara, bem como a evolução da própria revista nos aspectos editoriais, comercial e de design gráfico. Em seguida, selecionou-se 23 reportagens nas editorias de turismo, gastronomia, esportes e outras relacionadas à Cultura Caiçara, que tiveram seus discursos semânticos e os elementos valorativos de linguagens analisados. Nas conclusões, constatou-se que a cobertura jornalística da Beach&Co privilegia as áreas do turismo e do desenvolvimento do Litoral Norte e Baixada Santista; que a revista passou por readaptações e esquematismos dominantes na produção jornalística e encontrou mercado nas especificidades do Litoral Paulista; a Beach&Co se consolidou como uma revista regional profissional, de qualidade e criativa, distante do amadorismo, do bairrismo e da mimetização simplista; apesar de muitas vezes ter usado o caiçara para adjetivar os aspectos turísticos e gastronômicos do Litoral Norte, a revista trabalhou a produção simbólica do caiçara de forma ampla e retratou vários aspectos da Cultura Caiçara, reforçando o poder desta revista regional, como retroalimentando os sotaques do Litoral Paulista nas demais regiões do país onde a publicação também é lida.

Creative thinking experimentations for entrepreneurship with a disruptive, personalised and mobile game-based learning ecosystem

Based on an unprecedented need of stimulating creative capacities towards entrepreneurship to university students and young researchers, this paper introduces and analyses a smart learning ecosystem for encouraging teaching and learning on creative thinking as a distinct feature to be taught and learnt in universities. The paper introduces a mashed-up authoring architecture for designing lesson-plans and games with visual learning mechanics for creativity learning. The design process is facilitated by creativity pathways discerned across components. Participatory learning, networking and capacity building is a key aspect of the architecture, extending the learning experience and context from the classroom to outdoor (co-authoring of creative pathways by students, teachers and real-world entrepreneurs) and personal spaces. We anticipate that the smart learning ecosystem will be empirically evaluated and validated in future iterations for exploring the benefits of using games for enhancing creative mindsets, unlocking the imagination that lies within, practiced and transferred to multiple academic tribes and territories.

(Table 4+5, Page 290) Distribution of Mn, Fe, Cu. Pb, Zn, Ni and Co in single manganese nodules

Chemical analyses of manganese nodules from the Central Pacific Basin show that their chemical composition varies regionally, although that of the associated sediments is markedly uniform throughout the basin. Mn content varies from 16 to 32% in average. Its higher value is generally found in nodules from siliceous clay and a few from deep-sea clay. Fe content tends to enrich in nodules from deep-sea clay area. Most manganese nodules, except those from deep-sea clay, are remarkably depleted in Fe compared with ones from the other Pacific regions. Mostly, Cu and Ni contents exceed 1% in nodules from siliceous clay, and decrease towards the northwest of the basin where deep-sea clay is distributed. The inter-element relationship between manganese nodules and associated sediments suggests that the mechanism of incorporation of major and minor elements in nodules is apparently different from that of the associated sediments. This finding seems to provide a new interpretation on the problem why manganese nodules having low accumulation rate are not buried by the associated sediments with greater sedimentation rate and then occur on sediment-seawater interface.

Radiocarbon ages, grain sizes, paleomagentic properties and XRF data of Lake Nam Co sediments, Tibetan Plateau

In September 2008 several cores (68 cm-115 cm length) (water depth: 93 m) were retrieved from Lake Nam Co (southern-central Tibetan Plateau; 4718 m a.s.l.). This study focuses on the interpretation of high-resolution (partly 0.2 cm) data from three gravity cores and the upper part of a 10.4 m long piston core, i.e., the past 4000 cal BP in terms of lake level changes, hydrological variations in the catchment area and consequently variations in monsoon strength. A wide spectrum of sedimentological, geochemical and mineralogical investigations was carried out. Results are presented for XRF core-scans, grain size distribution, XRD-measurements and SEM-image analyses. These data are complemented by an age-depth model using 210Pb and 137Cs analyses as well as eleven AMS-14C-ages. This model is supported by excellent agreement between secular variations determined on one of the gravity cores to geomagnetic field models. This is a significant improvement of the chronology as most catchments of lacustrine systems on the Tibetan Plateau contain carbonates resulting in an unknown reservoir effect for radiocarbon dates. The good correlation of our record to the geomagnetic field models confirms our age-depth model and indicates only insignificant changes in the reservoir effect throughout the last 4 ka. High (summer-) monsoonal activity, i.e. moist environmental conditions, was detected in our record between approximately 4000 and 1950 cal BP as well as between 1480 and 1200 cal BP. Accordingly, lower monsoon activity prevails in periods between the two intervals and thereafter. This pattern shows a good correlation to the variability of the Indian Ocean Summer Monsoon (IOSM) as recorded in a peat bog ~1000 km in NE direction from Lake Nam Co. This is the first time that such a supra regional homogenous monsoon activity is shown on the Tibetan Plateau and beyond. Finally our data show a significant lake level rise after the Little Ice Age (LIA) in Lake Nam Co which is suggested to be linked to glacier melting in consequence of rising temperatures occurring on the whole Tibetan Plateau during this time.

Diversity in a simple co-crystal: racemic and kryptoracemic behaviour.

The crystal structure containing (+/-)-3-methyl-2-phenylbutyramide with salicylic acid is the first example of a kryptoracemate co-crystal. It exhibits the first temperature mediated reversible single-crystal to single-crystal transition between two kryptoracemate forms, in addition to crystallising in another, racemic, form. Theoretical calculations and structural analysis reveal that there are only small differences in both energy and packing arrangements between the three forms. These results suggest that co-crystals can be an opportunity to investigate kryptoracemate behaviour.

Sedimentary n-alkanes, their hydrogen isotopes, GDGTs and d15N as well as d13Corg of lake Nam Co, Tibet

The transition from the last Glacial to the current Interglacial, the Holocene, represents an important period with climatic and environmental changes impacting ecosystems. In this study, we examined the interplay between the Indian Ocean Summer Monsoon (IOSM) and the Westerlies at lake Nam Co, southern Tibet to understand the climatic effects on the ecosystem. Different organic geochemical proxies (n-alkanes, glycerol dialkyl glycerol tetraethers, dD, d13Corg, d15N) are applied to reconstruct the environmental and hydrological changes on one of the longest available paleorecords at the Tibetan Plateau. Based on our paleohydrological dD proxies, the aquatic signal lags the terrestrial one due to specific ecological thresholds, which, in addition to climatic changes, can influence aquatic organisms. The aquatic organisms' response strongly depends on temperature and associated lake size, as well as pH and nutrient availability. Because the terrestrial vegetation reacts faster and more sensitively to changes in the monsoonal and climatic system, the dD of n-C29 and the reconstructed inflow water signal represent an appropriate IOSM proxy. In general, the interplay of the different air masses seems to be primarily controlled by solar insolation. In the Holocene, the high insolation generates a large land-ocean pressure gradient associated with strong monsoonal winds and the strongest IOSM. In the last glacial period, however, the weak insolation promoted the Westerlies, thereby increasing their influence at the Tibetan Plateau. Our results help to elucidate the variable IOSM, and they illustrate a remarkable shift in the lake system regarding pH, d13Corg and d15N from the last glacial to the Holocene interglacial period.
