Reducing Legal Uncertainty: A Challenge for Subregional Integration in Latin America and the Caribbean

Despite the recovery in intraregional trade over the past three years, intra-group trade, that is trade within the Southern Common Market (MERCOSUR), the Andean Community (CAN) and the Central American Common Market (CACM), remains much weaker than that observed within similar groups in other regions of the world. This weakness is due essentially to the serious lack of complementarity in the process of eliminating tariff barriers (see chapter 3 of Latin America and the Caribbean in the World Economy 2004: Trends 2005, and the study on regional integration entitled: "América Latina y El Caribe: La integración regional en la hora de las definiciones", which is due to be published shortly and which updates basic information for the year 2005). The reasons include (a) weak institutional capacities; (b) the lack of macroeconomic coordination; (c) inadequate infrastructure and d) the lack of depth in integration-related trade disciplines.  This edition of the Bulletin reviews the mechanisms for dispute settlement within Mercosur, the Andean Community and CACM with a view to drawing conclusions on the extent to which they are used. In order to reform such mechanisms, consideration should be given to the creation of a single dispute settlement mechanism which would replicate the procedures and regulations of the World Trade Organization (WTO).

Social equity and changing production patterns: an integrated approach

In accordance with the mandate it received at the twenty-third session, in this document the secretariat has attempted to delve further into the links among technical progress, international competitiveness and social equity, although it does not, certainly, purport to have exhausted these subjects. Two qualifying remarks are called for here. First, the secretariat is deliberately abstaining from becoming embfoiled in the theoretical aspects of a controversy which has raged for centuries, and particularly since the French revolution, i.e., the debate surrounding the cause-and-effect relationships and possible areas of incompatibility among democratic governance, economic stability, growth and well-being. Rather than concerning itself with doctrine, the secretariat prefers to deal with the realities confronting virtually all the Governments of the region. These realities include the need to resume a sustained (and environmentally sustainable) growth process within the framework of the consolidation of pluralistic, democratic societies -societies that are faced with very real demands to address the many ways in which the majority of the population has been bypassed by development. Secondly, no attempt has been made in this document to provide a list of suitable policies for changing production patterns or for attaining greater social equity. Instead, the focus is on how certain pivotal analytical and policy aspects can be linked within an integrated approach so as to reinforce any existing areas of complementarity between efforts to achieve greater growth and efforts to seek greater social equity. This approach highlights the central tenet of the document: that growth, social equity and democracy can be compatible. What is more, there are significant but as yet largely unexplored areas in which social equity and changing production patterns complement and reinforce one another.

Inventário da araneofauna (Arachnida, Araneae) de serapilheria na Estação Científica Ferreira Penna, Pará, Brasil

A Estação Científica Ferreira Penna (ECFP), com aproximadamente 33.000 hectares, está localizada na Floresta Nacional de Caxiuanã, Pará. Com o objetivo de implementar um protocolo estruturado de inventario da fauna de aranhas de serapilheira da ECFP, foi obtido um total de 400 amostras concentradas de 1m² de serapilheira, nos períodos chuvoso e seco. As aranhas foram segregadas através da combinação das técnicas de triagem manual e de extratores de Winkler. Estas amostras foram provenientes de cinco parcelas. Três parcelas estão localizadas em mata de terra firme (LBA-EXP, LBA-CON e TF-IMC) e duas em mata de igapó (1G-N e IG-S). Uma das parcelas de terra firme sofre estresse hídrico (LBA-EXP), sendo a chuva excluída do solo por meio de painéis e calhas. Foram coletados 2230 indivíduos (5,6 indivíduos / m², em média), pertencentes a 34 famílias. Sete famílias foram representadas apenas por animais imaturos: Nesticidae, Pisauridae, Gnaphosidae, Mimetidae, Deinopidae, Oxiopidae, Uloboridae. As famílias mais abundantes foram Salticidae, Theridiidae, Ctenidae, Oonopidae e Linyphiidae. Foi obtido um total de 876 indivíduos adultos, atribuídos a 120 espécies ou morfo-espécies, em 27 famílias. As espécies com maior abundância relativa foram Styposis sp.3 (Theridiidae) com 16,55% do total de indivíduos adultos, Pseudanapis sp.1 (Anapidae) com 6,96%, Meioneta sp.1 (Linyphiidae) com 6,39%, Oonopidae sp.1 com 5,59% e Salticidae sp.1 com 4,56%. Para a maioria das análises, foram excluídas 15 espécies consideradas como ocasionais na serapilheira. As curvas de acumulação de espécies observadas para o total de amostras e para cada uma das parcelas não atingiram assíntotas ao final da adição de amostras. Os padrões de abundância e incidência destas espécies indicam a existência de uma riqueza real de 123 a 184 espécies. As maiores estimativas de riqueza em espécies foram encontradas na parcela LBA-EXP (75 - 110 espécies). As menores estimativas foram observadas em IG-N (25 - 59 espécies). Apesar da riqueza em espécies e a abundância de aranhas ter sido maior na parcela LBA-EXP, a diversidade foi maior nas parcelas LBA-CON e TF-IMC. A diversidade no igapó foi mais baixa do que na terra firme. A composição de espécies diferiu entre os ambientes de terra firme e igapó, de acordo com coeficientes de similaridade e complementaridade percentual. A abundância e a riqueza de espécies de aranhas de serapilheira aumentam no período seco e diminuem com o aumento da umidade residual do solo.

Comparison of the reliability of multifocal visual evoked cortical potentials generated by pattern reversal and pattern pulse stimulation

This study compared the effectiveness of the multifocal visual evoked cortical potentials (mfVEP) elicited by pattern pulse stimulation with that of pattern reversal in producing reliable responses (signal-to-noise ratio >1.359). Participants were 14 healthy subjects. Visual stimulation was obtained using a 60-sector dartboard display consisting of 6 concentric rings presented in either pulse or reversal mode. Each sector, consisting of 16 checks at 99% Michelson contrast and 80 cd/m2 mean luminance, was controlled by a binary m-sequence in the time domain. The signal-to-noise ratio was generally larger in the pattern reversal than in the pattern pulse mode. The number of reliable responses was similar in the central sectors for the two stimulation modes. At the periphery, pattern reversal showed a larger number of reliable responses. Pattern pulse stimuli performed similarly to pattern reversal stimuli to generate reliable waveforms in R1 and R2. The advantage of using both protocols to study mfVEP responses is their complementarity: in some patients, reliable waveforms in specific sectors may be obtained with only one of the two methods. The joint analysis of pattern reversal and pattern pulse stimuli increased the rate of reliability for central sectors by 7.14% in R1, 5.35% in R2, 4.76% in R3, 3.57% in R4, 2.97% in R5, and 1.78% in R6. From R1 to R4 the reliability to generate mfVEPs was above 70% when using both protocols. Thus, for a very high reliability and thorough examination of visual performance, it is recommended to use both stimulation protocols.

Indícios de subjetividade na fala de uma criança psicótica: um olhar para as hesitações

This study, performed under a linguistic-discoursive prism, aimed to: (1) describe the moments in which occurred hesitations in the utterances of a psychotic child diagnosed with Language Disorder; and (2) determine the extent to which these moments (also) can indicate aspects of a subjectivity trying to emerge in this child. Data were extracted from a speech therapy session with a ten year old female child. Concerning the fi rst goal, from a total of 362 utterances produced by the child, only 74 (20%) had hesitation traces, while 288 (80%) did not. Concerning the second goal, the utterances with hesitation traces occurred in situations of: topic development, especially in the form of complementarity; introduction of new topic; return to the previous topic; refuses to the topic; enunciative incompleteness. The high percentage of utterances without hesitation traces (80%) is explained because they are highly predictable from the context, mostly in situations of ritualized adjacent pairs, oftentimes in situations of immediate specularity. The reduced percentage of utterances with hesitation traces are explained precisely by the fact that, unlike those without traces, in these ones, signs of a subjectivity that tries to emerge and show itself in the discourse production are detected. With the development of this study, we tried to emphasize the view at the hesitations as marks of subjectivity – in other words, evidences of confl icting relationships between the subject and the others that constitute the utter. The concern was also about bringing to the fi eld of Speech Pathology discoursive linguistic refl ections based on data extracted from symptomatic contexts of language.

A pesquisa sobre o fazer pesquisa: uma análise de citação da literatura periódica em Ciência da Informação

Introduction: This paper considers that information science (IS) literature covers a diversity of thematics with low emphasis on researches about conducting research. The study analyzes the scientific production of authors who investigate about research methodology in the information science (IS) literature, and the references used to lay the foundation of the methodological issues regarding the area. It discusses the methodological and epistemological positions of the leading researchers highlighted as the most productive investigators on the subject in the country. Method: The research adopts the content analysis coupled with metric studies to contextualize the indicators related to productivity, to the types of authorship and citation analysis. The bibliographic coupling method is considered an analysis mode which analyzes concomitant citations. It develops a theoretical framework about the importance of scientific production analysis in different knowledge fields. The study investigates, from a theoretical perspective, the concepts about research methodology and the complementarity between methodology and epistemology in conducting research. Results: The results of the analysis showed that the production of the highlighted authors presents the methodology as a thematic focus to be applied to IS contexts, as well as a research object in the field. The prominent productivity of the authors is justified especially by deepening the meta studies about the ways to conduct research in IS. This study also identifies a trend to single-authored studies about the theme. Conclusions: The research considers that meta studies and applied and methodological studies are important to recognize a consistent theoretical and practical core in the IS area. Regarding the epistemological influences identified by the citation analysis, the study observes that the critical rationalist epistemology and the social and political epistemology are highlighted in the construction of the theoretical framework of the most productive authors.
