The determinantss of foreign direct investment distribution among the Brazilian states

O Investimento Estrangeiro Direto (IED) tem desempenhado um papel importante no esforço do Brasil para tornar-se uma economia orientada para o mercado. De 1995 a 2012 o Brasil recebeu $ 511.5 bilhões de dólares em IED. Em 2012, o Brasil foi o segundo país em desenvolvimento que mais recebeu IED e o quarto no mundo (UNCTAD).Devido à concentração geográfica, os estados brasileiros que são consideravelmente menos desenvolvidos e mais pobres, são aqueles que mais precisam de investimentos e que no entanto, não têm sido receptores relevantes de IED. Em 2010, os estados com os maiores estoques de IED foram São Paulo, com 42,3 por cento do total ($ 99,9 bilhões de dólares), Rio de Janeiro com 13,3 por cento ($ 31,4 bilhões de dólares) e Minas Gerais com 10,6 por cento do total ($ 25,1 bilhões de dólares). Como pode ser observado, apenas três dos vinte e sete estados brasileiros receberam cerca de 66 por cento do total de IED destinado ao Brasil.Dada tal diferenciação na distribuição de IED entre os estados brasileiros, o presente estudo busca explicar se o benefício tributário também é determinante para o fluxo de IED, além das demais variáveis já consideradas como determinantes em outros estudos. Dada a limitação de dados, realizamos duas análises econométricas com dados em painel: 1. Usando seis variáveis chaves: tamanho do mercado consumidor, a qualidade da mão de obra, infraestrutura, custo da mão de obra, carga tributária e benefício tributário (por macro regiões), nos anos de 1995, 2000, 2005 and 2010; 2. Usando cinco variáveis: as mesmas do primeiro modelo, excluindo o custo da mão de obra (por falta de dados) e utilizando os dados de benefício tributário por estado, nos anos de 2010, 2011 e 2012.

Estimating abundance and spatial distribution patterns of the bubble crab Dotilla fenestrata (Crustacea : Brachyura)

The bubble crab Dotilla fenestrata forms very dense populations on the sand flats of the eastern coast of Inhaca Island, Mozambique, making it an interesting biological model to examine spatial distribution patterns and test the relative efficiency of common sampling methods. Due to its apparent ecological importance within the sandy intertidal community, understanding the factors ruling the dynamics of Dotilla populations is also a key issue. In this study, different techniques of estimating crab density are described, and the trends of spatial distribution of the different population categories are shown. The studied populations are arranged in discrete patches located at the well-drained crests of nearly parallel mega sand ripples. For a given sample size, there was an obvious gain in precision by using a stratified random sampling technique, considering discrete patches as strata, compared to the simple random design. Density average and variance differed considerably among patches since juveniles and ovigerous females were found clumped, with higher densities at the lower and upper shore levels, respectively. Burrow counting was found to be an adequate method for large-scale sampling, although consistently underestimating actual crab density by nearly half. Regression analyses suggested that crabs smaller than 2.9 mm carapace width tend to be undetected in visual burrow counts. A visual survey of sampling plots over several patches of a large Dotilla population showed that crab density varied in an interesting oscillating pattern, apparently following the topography of the sand flat. Patches extending to the lower shore contained higher densities than those mostly covering the higher shore. Within-patch density variability also pointed to the same trend, but the density increment towards the lowest shore level varied greatly among the patches compared.

Description of new cicada species associated with the coffee plant and an identification key for the species of Fidicinoides (Hemiptera: Cicadidae) from Brazil

The genus Fidicinoides Boulard & Martinelli is characterized by its partially exposed timbal, not totally covered by the meta-scutellar plate as occurs in Fidicina Amyot & Serville, and has an extensive geographic distribution in Central and South America. In this work a new species for the genus is described. Fidicinoides sarutaiensis Santos, Martinelli & Maccagnan sp. n. is a medium-sized cicada, with the collected and studied specimens associated with coffee (Coffee arabica L.), in the municipality of Sarutaia, in the southeast region of São Paulo state. The species F. glauca (Goding, 1925) and F. viridifemur (Walker, 1850) are transferred to Dorisiana. An identification key for the Fidicinoides species of Brazil is also proposed.

Description of the female and new records of Triatoma baratai Carcavallo & Jurberg, 2000 (Hemiptera: Heteroptera: Reduviidae: Triatominae) from Mato Grosso do Sul, Brazil, with a key to the species of the Triatoma matogrossensis subcomplex

Triatoma baratai Carcavallo & Jurberg, 2000, a species similar to Triatoma williami Galvao, Souza & Lima, 1967 and belonging to the T. matogrossensis subcomplex, was described based on a male specimen collected in a sylvatic environment, near a cave, in Bonito county, Bodoquena mountain range, state of Mato Grosso do Sul, Brazil. In the present work we describe the female of T. baratai, captured in a chicken house, in Nioaque county, state of Mato Grosso do Sul, Brazil. Furthermore, we recorded the occurrence of T. baratai in domiciles and peridomestic environment in another four municipalities (Bodoquena, Bela Vista, Corumba, and Miranda), extending its geographical distribution. Finally, we present a key to the species of the Triatoma matogrossensis subcomplex.

Abundance and ecologic distribution of the shrimp Rimapenaeus constrictus (Crustacea : Penaeidae) on the northern coast of São Paulo State, Brazil

The abundance and ecologic distribution of the shrimp R. constrictus were compared among three different embayments within the northern coast of São Paulo State (23degreesS, 45degreesW); i.e. Mar Virado (MV), Ubatuba (UBA) and Ubatumirim (UBM). Key environmental factors were monitored for a better understanding of the distributional patterns of this species, namely temperature, salinity, depth, organic matter content and texture of sediments. In each bay, six transects were delimited, four parallel to the coastline and the other two in areas adjacent to rocky shores. Monthly samples were taken over a 2-year period (1998 and 1999), using a shrimp fishing boat equipped with double-rig nets. Abundance data were treated separately according to environmental characteristics. A total of 4978 specimens was obtained; 921 at MV, 1948 at UBA and 2109 at UBM. The spatial distribution of R. constrictus differed among bays. Higher abundance values were recorded at areas where silt and clay comprised less than 70% of the sediment. A more diversified sediment at UBM and UBA apparently favours the establishment of this species in the region. Its abundance also followed a seasonal trend, higher during spring and summer when intrusions of cold South Atlantic Coastal Waters (SACW) are frequent, promoting the migration of this shrimp to more sheltered areas. These results suggest that sediment type and temperature are the most important variables affecting the spatial and seasonal distribution of this species.

DISTRIBUTION AND SEASONAL DYNAMICS OF RHODOPHYTA IN THE PRETO RIVER BASIN, SOUTHEASTERN BRAZIL

Distribution and seasonal dynamics of freshwater Rhodophyta were investigated in the Preto River basin, located in northwestern São Paulo State, southeastern Brazil. Twenty-two sites were sampled, six monthly during one year, four bimonthly during two years, and 12 twice (hot-rainy and cool-dry seasons) during the study period (May 1989 through March 1991). Red algal representatives were found in 19 sites (86.4%). Four species occurred in the basin with varying frequencies: Batrachospermum delicatulum (54.5%), Compsopogon coeruleus (36.4%), B. bicudoi (13.6%) and B. virgatum (4.5%). In addition, 'Chantransia' stage of the batrachospermalean species was found in 17 sites (77.3%). B. bicudoi, B. virgatum and C. coeruleus occurred only in large stream segments (greater-than-or-equal-to 3-order), generally in the main river, whereas B. delicatulum was more frequent in small streams (less-than-or-equal-to 3-order). The stream variables most closely related to the species distribution in the basin were specific conductance, pH and oxygen. B. bicudoi and B. delicatulum showed a marked seasonality: gametophytes were observed from late fall to early spring, while the 'Chantransia' stage generally occurred throughout the year. C. coeruleus was observed throughout the year in most sites, but the populations were generally more abundant from late fall to early spring. The combination of lower temperature and reduced turbidity resulting in increased illumination to the benthic algae during the dry winter months promotes the gametophytic growth of the batrachospermalean species, whereas current velocity was found to be the most influential stream variable for C. coeruleus. The persistance of the 'Chantransia' stage throughout the year as well as its tolerance to wider environmental conditions are key factors in the efficiency of the batrachospermalean life history strategy in lotic ecosystems.

Proposals for improvement of methodology and process of collecting and analyzing compatibility of power quality indicators in distribution systems

This article aims to present proposals for improvement of key standards and resolutions concerned about the methodology for calculating the indicator of total harmonic voltage distortion, and should contribute to the process of examining the compatibility of potentially disturbing loads in electric power quality in distribution systems. These proposals were drawn from the analysis of results from measurement campaigns conducted in a case study including analysis of the connection of a new induction furnace in a foundry served by a distributor of São Paulo state. A general historical situating the quality of electric energy in the electricity sector is presented, and methodological guidelines and procedures used in experimental trials are shown. The analysis and discussion of results are prepared to answer the main questions that arise during the implementation of standards, resolutions and procedures. © 2011 IEEE.

Wavespeed measurement in buried water distribution pipes and its significance in leak location

To determine the location of leaks in buried water pipes, acoustic methods are often used. These have proven to be very effective in metallic pipes but have been problematic in modern plastic pipes. In this paper the reason why this is so is discussed together with some measurements that were made on a bespoke test rig built by South Staffs Water plc. A particular problem is the estimate of the wavespeed. Tables are frequently used for this purpose, but these are often inaccurate and this means that a leak cannot be located accurately. An in-situ measure of the wavespeed is thus preferable. In this paper it is shown that there are significant issues in obtaining an accurate estimate of the wavespeed when a leak is present in the system. A method is proposed that overcomes some of these problems, which is discussed and is demonstrated using some data from the bespoke test-rig. © (2013) Trans Tech Publications.

The employment situation in Latin America and the Caribbean: Employment formalization and labour income distribution

The employment situation in Latin America and the Caribbean is a twice-yearly report prepared jointly by the Economic Development Division of the Economic Commission for Latin America and the Caribbean (ECLAC) and the Subregional Office for the South Cone of Latin America of the International Labour Organization (ILO). Strong job creation and wage gains have proved to be a key factors in reducing poverty —quite substantially— in our region over the past decade. Together with the implementation of innovative social policies, the narrowing of wage gaps has played a fundamental role in reducing inequality between households. The success of these two processes —reducing poverty and inequality— count among the most important achievements of this period. In the past few years, however, the fight against poverty has noticeably lost momentum,1 showing the extent to which job creation has been hit by the recent economic slowdown.

Cross-layer optimizations for multimedia distribution over Wireless Multimedia Sensor Networks and Flying Ad-Hoc Networks with quality of experience support

The proliferation of multimedia content and the demand for new audio or video services have fostered the development of a new era based on multimedia information, which allowed the evolution of Wireless Multimedia Sensor Networks (WMSNs) and also Flying Ad-Hoc Networks (FANETs). In this way, live multimedia services require realtime video transmissions with a low frame loss rate, tolerable end-to-end delay, and jitter to support video dissemination with Quality of Experience (QoE) support. Hence, a key principle in a QoE-aware approach is the transmission of high priority frames (protect them) with a minimum packet loss ratio, as well as network overhead. Moreover, multimedia content must be transmitted from a given source to the destination via intermediate nodes with high reliability in a large scale scenario. The routing service must cope with dynamic topologies caused by node failure or mobility, as well as wireless channel changes, in order to continue to operate despite dynamic topologies during multimedia transmission. Finally, understanding user satisfaction on watching a video sequence is becoming a key requirement for delivery of multimedia content with QoE support. With this goal in mind, solutions involving multimedia transmissions must take into account the video characteristics to improve video quality delivery. The main research contributions of this thesis are driven by the research question how to provide multimedia distribution with high energy-efficiency, reliability, robustness, scalability, and QoE support over wireless ad hoc networks. The thesis addresses several problem domains with contributions on different layers of the communication stack. At the application layer, we introduce a QoE-aware packet redundancy mechanism to reduce the impact of the unreliable and lossy nature of wireless environment to disseminate live multimedia content. At the network layer, we introduce two routing protocols, namely video-aware Multi-hop and multi-path hierarchical routing protocol for Efficient VIdeo transmission for static WMSN scenarios (MEVI), and cross-layer link quality and geographical-aware beaconless OR protocol for multimedia FANET scenarios (XLinGO). Both protocols enable multimedia dissemination with energy-efficiency, reliability and QoE support. This is achieved by combining multiple cross-layer metrics for routing decision in order to establish reliable routes.
