Identification of predominant economic agents and asymmetric regulation

In recognition of the telecommunications industry’s increasing importance for the growth and competitiveness of Latin American countries, this edition of the FAL Bulletin is based on the presentation given by Mr. Patricio Rozas of the Infrastructure Services Unit of the Economic Commission for Latin America and the Caribbean (ECLAC), at the International Forum on New Telecommunications and Broadcasting Models, organized by the Senate of the Republic of Mexico and held in Mexico City between 28 and 30 October 2013.

Economic and Social Upgrading: Definitions, connections and exploring means of measurement

This paper reviews and synthesizes the literature on social upgrading, while exploring its connections with economic upgrading. Using the parsimonious method proposed by Bernhardt and Milberg and an alternative method that takes into account increases in national productivity, this paper analyzes the case of Mexico. Though the proposed approach to social upgrading can be made more sophisticated through the inclusion of more variables, in order to facilitate the replication of the analysis in developing countries where data are scarce, labor productivity, wages and employment were considered sufficient information to analyze economic and social upgrading.

Population analysis of Scomberomorus cavalla (Cuvier, 1829) (Perciformes, Scombridae) from the Northern and Northeastern coast of Brazil

Scomberomorus cavalla é uma espécie de peixe pelágico amplamente distribuído na costa oeste do Atlântico, e uma diminuição no seu nível de captura tem sido verificada nos E.U.A e Golfo do México, comparada com os níveis alcançados pela espécie no passado. Da mesma forma, em algumas áreas do Brasil, há indícios de sobre-exploração. Entretanto, não existem estudos moleculares que visam o manejo deste importante item. Desta forma, no presente estudo, foram seqüenciados 380 pares de bases nucleotídicas da região da Alça-D do DNA mitocondrial de amostras provenientes de desembarque em Macapá, Bragança e Fortaleza. As análises filogenéticas e populacionais revelaram que há apenas uma população panmítica e baixos níveis de variabilidade genética foram observados. Estes resultados, assim como a observada sobre-exploração de S. cavala, representam dados muito importantes para o estabelecimento do manejo deste estoque a fim de prevenir um colapso ou risco de extinção no futuro.

The genus Mansoa (Bignoniaceae): a source of organosulfur compounds

O gênero Mansoa pertence à família Bignoniaceae e inclui onze espécies que ocorrem principalmente nas florestas secas e úmidas do Brasil e da Argentina até o Sudeste do México. Essas espécies na Amazônia brasileira são conhecidas como "cipó-de-alho", em referência ao forte cheiro de alho das folhas quando esmagadas. O "cipó-de-alho" tem vários usos na medicina tradicional e entre eles, os mais citados são para tratamento de gripe, febre, dor e inflamação de artrite e reumatismo. Apesar de todos os usos, ainda tem pequena aplicação como fitoterápico quando comparado ao alho (Allium sativum). Os óleos essenciais de Mansoa spp. contêm polissulfetos de alila que contribuem para o aroma e sabor característicos. A composição química dos extratos orgânicos de Mansoa incluiu alcanos, alcanóis, triterpenóides, flavonóides, derivados do lapachol e o derivado sulfurado aliína. Os usos, composição química, atividades biológicas e aspectos agrícolas de espécies de Mansoa e sua relação com A. sativum são apresentados.

Outcome of the agrarian reform in Brazil during the last two decades

The agrarian reform allows for land redistribution and gives rural workers the opportunity to develop their life projects, rescuing the dignity of a historically excluded population. The conquest of the land carries significances that span from the rescue of citizenship to the improvement of living conditions due to the acquisition of goods, products and services. It is pointed out that in Brazil there still exists a marked concentration of large-landed estates. In this sense, this work had the objective of analyzing the Brazilian agrarian reform process during the last two decades. In this period the country had three Presidents, two of them elected with the support of the Rural Landless Workers Movement, increasing the expectations in relation to the fulfillment of the agrarian reform. The advances in the policies of rural settlements are notable; however, the structure of large-land estates remains unaltered. In the last two years (2011 and 2012) the number of settled families, as well as the number of settlements accomplished, were the worst since 2006. The priority of the current government is the eradication of extreme poverty and, in this sense, the agrarian reform becomes an essential policy to contribute to such goal, since with the distribution of the property of the land also diminishes the concentration of wealth.

Molecular barcode and morphological analyses reveal the taxonomic and biogeographical status of the striped-legged hermit crab species Clibanarius sclopetarius (Herbst, 1796) and Clibanarius vittatus (Bosc, 1802) (Decapoda: Diogenidae)

The taxonomic status of the species Clibanarius sclopetarius (Herbst, 1796) and Clibanarius vittatus (Bosc, 1802), which have sympatric biogeographical distributions restricted to the western Atlantic Ocean, is based only on differences in the colour pattern of the walking legs of adults. Their morphological similarity led to the suggestion that they be synonymised. In order to investigate this hypothesis, we included species of Clibanarius Dana, 1892 in a molecular phylogenetic analysis of partial sequences of the mitochondrial 16S rDNA gene and the COI barcode region. In addition, we combined the molecular results with morphological observations obtained from several samples of these two species. The genetic divergences of the 16S rDNA and COI sequences between C. sclopetarius and C. vittatus ranged from 4.5 to 5.9% and 9.4 to 11.9%, which did not justify their synonymisation. Differences in the telson morphology, chela ornamentation, and coloration of the eyestalks and antennal peduncle provided support for the separation of the two species. Another interesting result was a considerable genetic difference found between populations of C. vittatus from Brazil and the Gulf of Mexico, which may indicate the existence of two homonymous species.

Experimental comparative study on vortex-induced motion (VIM) of a monocolumn platform

An analysis methodology is presented as well as a comparison of results obtained from vortex-induced motion (VIM) model tests of the MonoGoM platform, a monocolumn floating unit designed for the Gulf of Mexico. The choice of scale between the model and the platform in which the tests took place was a very important issue that took into account the basin dimensions and mooring design. The tests were performed in three different basins: the IPT Towing Tank in Brazil (Sept. 2005), the NMRI Model Ship Experimental Towing Tank in Japan (Mar. 2007), and the NMRI Experimental Tank in Japan (Jun. 2008). The purpose is to discuss the most relevant issues regarding the concept, execution, and procedures to comparatively analyze the results obtained from VIM model tests, such as characteristic motion amplitudes, motion periods, and forces. The results pointed out the importance of considering the 2DOF in the model tests, i.e., the coexistence of the motions in both in-line and transverse directions. The approach employed in the tests was designed to build a reliable data set for comparison with theoretical and numerical models for VIM prediction, especially that of monocolumn platforms.

Reproductive biology of the ghost shrimp Lepidophthalmus bocourti (A. Milne-Edwards, 1870) (Decapoda: Axiidea: Callianassidae): A tropical species with a seasonal reproduction

Based on the hypothesis that reproduction is a continuous process in tropical habitats, we analysed reproductive periodicity and egg production in the callianassid ghost shrimp Lepidophthalmus bocourti, one of the most common species in mangrove systems along the Pacific coast of Central America. During one year (May 2008 to April 2009), individuals of L. bocourti (N = 499) were collected nearshore Gulf of Nicoya, Pacific coast of Costa Rica. Observations were made on presence or absence of incubated embryos, and gonad activity of females was analysed as gonadosomatic index (GSI). Our results revealed that L. bocourti has a marked seasonal breeding period, which contradicts previous reports regarding coastal marine decapods from the tropics. Ovigerous females were found only from June to August, while high GSI values were obtained from March to July. The increase of GSI and appearance of ovigerous females were associated with a concomitant decrease of salinity, but not with temperature. We assume that reproduction of L. bocourti is adapted to local changes of environmental conditions, and that a decrease in salinity during rainy season may serve as a triggering factor for ovarian development. Compared to other ghost shrimps, L. bocourti produced on average more (2002 +/- 1365) and smaller (0.87 +/- 0.109 mm) eggs, which seems to suggest that this species does not have an abbreviated larval development as reported for other species of genus. The deviation from the generalization of constant reproduction in the tropics for shallow water marine invertebrates and its probable cause are adequately discussed.

The use of remote sensing imagery for monitoring recovery in the aftermath of a natural disaster: the Hurricane Katrina Case

Although Recovery is often defined as the less studied and documented phase of the Emergency Management Cycle, a wide literature is available for describing characteristics and sub-phases of this process. Previous works do not allow to gain an overall perspective because of a lack of systematic consistent monitoring of recovery utilizing advanced technologies such as remote sensing and GIS technologies. Taking into consideration the key role of Remote Sensing in Response and Damage Assessment, this thesis is aimed to verify the appropriateness of such advanced monitoring techniques to detect recovery advancements over time, with close attention to the main characteristics of the study event: Hurricane Katrina storm surge. Based on multi-source, multi-sensor and multi-temporal data, the post-Katrina recovery was analysed using both a qualitative and a quantitative approach. The first phase was dedicated to the investigation of the relation between urban types, damage and recovery state, referring to geographical and technological parameters. Damage and recovery scales were proposed to review critical observations on remarkable surge- induced effects on various typologies of structures, analyzed at a per-building level. This wide-ranging investigation allowed a new understanding of the distinctive features of the recovery process. A quantitative analysis was employed to develop methodological procedures suited to recognize and monitor distribution, timing and characteristics of recovery activities in the study area. Promising results, gained by applying supervised classification algorithms to detect localization and distribution of blue tarp, have proved that this methodology may help the analyst in the detection and monitoring of recovery activities in areas that have been affected by medium damage. The study found that Mahalanobis Distance was the classifier which provided the most accurate results, in localising blue roofs with 93.7% of blue roof classified correctly and a producer accuracy of 70%. It was seen to be the classifier least sensitive to spectral signature alteration. The application of the dissimilarity textural classification to satellite imagery has demonstrated the suitability of this technique for the detection of debris distribution and for the monitoring of demolition and reconstruction activities in the study area. Linking these geographically extensive techniques with expert per-building interpretation of advanced-technology ground surveys provides a multi-faceted view of the physical recovery process. Remote sensing and GIS technologies combined to advanced ground survey approach provides extremely valuable capability in Recovery activities monitoring and may constitute a technical basis to lead aid organization and local government in the Recovery management.
