Report on expert group meeting on macroeconomic modelling in the Caribbean: new challenges and new directions

The purpose of the expert group meeting was to bring together modelling practitioners to share experiences and to reflect on how to overcome new and old challenges to model building in the Caribbean. As part of the rationale for such a meeting, it was argued that since a major objective of policymaking in the Caribbean was to create the conditions for growth with equity while reducing vulnerability to economic and environmental shocks, model builders must develop strategies to properly address those questions in a unified way. It was further suggested that those goals, though straightforward, required a concentrated technical effort to clarify and update understanding of the workings of Caribbean economies. The emphasis on addressing issues of growth, equity and vulnerability was urgent because Caribbean economies were at a crossroads, with major challenges to the foundations and premises on which the economies had been built.

New maritime transport scenarios. Part II: fluctuations in shipping and new scenarios

This FAL Bulletin details the situation of the shipping industry and forms the second and final part of a larger document that begins with Issue No. 338, which puts the current status of maritime trade in context. Both documents fit into a series of bulletins about ports and maritime trade in the region and are, therefore, closely linked to Issue No. 337, which sets out the need for a new port governance in the region to address the new circumstances that have arisen in the maritime market.

The prion protein and New World primate phylogeny

The PrPC prion protein contains 250 amino acids with some variation among species and is expressed in several cell types. PrPC is converted to PrPSc by a post-translational process in which it acquires amino acid sequences of three-dimensional conformation of -sheets. Variations in the prion protein gene were observed among 16 genera of New World primates (Platyrrhini), and resulted in amino acid substitutions when compared with the human sequence. Seven substitutions not yet described in the literature were found: W  R at position 31 in Cebuella, T  A at position 95 in Cacajao and Chiropotes, N S at position 100 in Brachyteles, L  Q at position 130 in Leontopithecus (in the sequence responsible for generating the -sheet 1), D  E at position 144 in Lagothrix (in the sequence responsible for the -helix 1), D G at position 147 in Saguinus (also located in the -helix 1 region), and M  I at position 232 in Alouatta. The phylogenetic trees generated by parsimony, neighbor-joining and Bayesian analyses strongly support the monophyletic status of the platyrrhines, but did not resolve relationships among families. However, the results do corroborate previous findings, which indicate that the three platyrrhine families radiated rapidly from an ancient split.

State-civil society partnership: issues for debate and new researches

Neste artigo analisamos a literatura de parceria entre o estado e a sociedade civil, em particular sobre a parceria entre as organizações públicas e as organizações sem fins lucrativos. Discutimos as diferentes perspectivas do conceito de parceria e objetivamos destacar algumas das principais preocupações teóricas sobre este conceito no contexto da governança. Buscamos mostrar que, em geral, o contexto histórico da parceria não tem sido incluído entre os fatores usados para explicar o seu uso no contexto da governança. Apontamos que, a despeito das análises sobre parceria que indicam que esta traz benefícios sociais, ainda existem lacunas no conhecimento que evidenciem que esta "tecnologia social" contribui efetivamente para empoderar as pessoas e os grupos sociais com menor poder de influência. A maior parte da literatura sugere que a parceria objetiva fortalecer a relação entre a população e o governo local e melhorar as possibilidades das pessoas e dos grupos sociais com menor poder de influência em participar na governança local. Entretanto, não encontramos na literatura sobre parceria evidências substantivas de que ela se direciona para modificar a estrutura de poder político. Finalmente, mostramos que não está claro se a interação entre as "pessoas comuns" e o estado, por via de um processo participativo, tem contribuído efetivamente para construir coesão social para diferentes grupos sociais. A principal contribuição do artigo é expandir o conhecimento dos fatores que influenciam (de forma positiva e negativa) o processo de parceria entre o estado e a sociedade civil para o desenvolvimento local.

Influence of light source and immersion media in surface roughness and hardness of a nanofilled composite resin

The study evaluated the influence of light curing units and immersion media on superficial roughness and microhardness of the nanofilled composite resin Supreme XT (3M/ESPE). Light curing units used were: XL 3000 (3M/ESPE), Jet Lite 4000 Plus (JMorita) and Ultralume Led 5 (Ultradent) and immersion media were artificial saliva, Coke®, tea and coffee, totaling 12 experimental groups. Specimens (10mm x 2mm) were immersed in each respective solution for 5 seconds, three times a day, during 60 days and so, were submitted to measure of superficial roughness (Ra) and Vickers hardness. Data were subjected to two-way ANOVA test (p<0.05). Results showed that only the light source factor showed statistically difference for hardness. It was observed that the hardness of the composite resin Filtek Supreme XT (3M/ESPE) was influenced by the light source (p<0.01) independently of the immersion media (p= 0.35) and the Jet Lite 4000 Plus (JMorita) was the light curing unit that presented lower values. In relation to surface roughness, it was noted no-significant statistical difference for light source (p=0.84), when specimens were immersed in different beverages (p=0.35).

Chemical and morphological features of dental composite resin: influence of light curing units and immersion media

Aims: The study evaluated the influence of light curing units and immersionmedia on superficial morphology and chemistry of the nanofilled composite resin Supreme XT (3M)through the EDX analysis and SEM evaluation. Light curing units with different power densitiesand mode of application used were XL 3000 (480 mW/cm2), Jet Lite 4000 Plus (1230mW/cm2), andUltralume Led 5 (790 mW/cm2) and immersion media were artificial saliva, Coke1, tea and coffee,totaling 12 experimental groups. Specimens (10 mm 3 2 mm) were immersed in each respectivesolution for 5 min, three times a day, during 60 days and stored in artificial saliva at 378C 6 18Cbetween immersion periods. Topography and chemical analysis was qualitative. Findings: Groupsimmersed in artificial saliva, showed homogeneous degradation of matrix and deposition of calciumat the material surface. Regarding coffee, there was a reasonable chemical degradation with loss ofload particles and deposition of ions. For tea, superficial degradation occurred in specific areaswith deposition of calcium, carbon, potassium and phosphorus. For Coke1, excessive matrix degra-dation and loss of load particles with deposition of calcium, sodium, and potassium. Conclusion:Light curing units did not influence the superficial morphology of composite resin tested, but theimmersion beverages did. Coke1affected material’s surface more than did the other tested drinks.Microsc. Res. Tech. 73:176–181, 2010.
