Impact of Sanitary and Technical Measures on Brazilian Exports of Poultry Meat

The major objective of this work is to evaluate the effects of technical and sanitary measures introduced by the main world importers upon Brazilian poultry meat in the international market. The impact of the measures is estimated using a gravity model constructed with disaggregated data about bilateral poultry meat between Brazil and its major trade partners for the period from 1996 to 2009. The gravity model is estimated with a fixed effects model and the results indicate that the impact of TBT and SPS measures upon Brazilian poultry meat exports is ambiguous. The results indicated that the existence of technical and sanitary regulations related to labelling might be stimulating trade of this product, while the presence regulations related to compliance appears to reduce the volume of Brazilian exports of poultry meat. In addition, the existence of prohibitive (and/or subject to quarantine) technical and sanitary measures may present a positive impact upon the traded volume of Brazilian exports of poultry meat. This result is relevant since it indicates the importance in considering different characteristics and content of regulations to analyse the impacts of TBT and SPS measures upon trade.Technical and Sanitary measure, Poultry meat, Gravity equation, International Relations/Trade,

IMPORTÂNCIA DAS EXIGÊNCIAS TÉCNICAS À EXPORTAÇÃO DE EMPRESAS BRASILEIRAS

This article presents results of a survey applied to Brazilian exporting firms to obtain primary data, which are subject to a statistical analysis about the relative importance attributed to technical barriers to trade. The methodological procedure used consisted in Rio Branco – Acre, 20 a 23 de julho de 2008 Sociedade Brasileira de Economia, Administração e Sociologia Rural factor analysis. This allowed the construction of three indexes: Traditional determinants Index - ICOND, Trade Impediments Index - IIMP and Technical requirements Index - IEXIG. The results indicated that technical requirements effects are different than other variables that affect exports. Additionally, the firms surveyed considered the IEXIG more restrictive than IIMP to their exports. This perception is different within the sectors evaluated.technical barriers, Brazilian exports, factor analysis, International Relations/Trade,

Heterogeneity Index of Trade and Actual Heterogeneity Index – the case of maximum residue levels (MRLs) for pesticides

Non-tariff measures (NTMs) beyond traditional trade policy instruments define the requirements that importing countries imposed on foreign products. Due to differences across countries, requirements for supplying foreign markets can lead to trade costs and thus hamper international trade. In this paper, we introduce two regulatory heterogeneity indexes which are subsequently applied to the case maximum residue levels (MRLs) of pesticides. The Heterogeneity Index of Trade (HIT) reflects the respective differences across countries based on the assumption that the mere fact of difference in requirements causes trade costs. Taking the HIT index as a starting point, the Actual Heterogeneity Index (AHI) specially considers the situation where the requirements demanded by the importing country are stricter than those of the exporting country. The focuses is on the pesticide MRLs that the EU27 and 10 trade partner countries (Argentina, Australia, Brazil, Canada, China, Japan, New Zealand, Russia and the US) apply on a set of agri-food products (cheese, beef, pig meat, potatoes, tomatoes, apples and pears, aubergines, peppers, maize, barley and rape seed). In particular, we take the EU export perspective as the benchmark for the comparison and calculate the indexes. The indexes identify if the respective MRLs are similar or dissimilar, equal, stricter or more lenient, and the results of our analysis thus point out potential areas for negotiating equivalence or other strategies in order to overcome the possible trade-restricting impact of diverging MRLs.Non-tariff measures (NTMs), maximum residue levels (MRLs), regulatory heterogeneity index, agri-food trade, index analysis, Agricultural and Food Policy, International Relations/Trade, Research Methods/ Statistical Methods,

MACROECOLOGIA, BIOGEOGRAFIA E ÁREAS PRIORITÁRIAS PARA CONSERVAÇÃO NO CERRADO

revista vol 13 nº 3.indd Há consenso entre os cientistas de que a há atualmente uma “crise da biodiversidade”, resultado da constante e intensa perda de habitat natural causada pela expansão da ocupação. Como a biologia da conservação tem sido muitas vezes reconhecida como uma ciência da crise, ela deve fornecer informações capazes de mediar, de forma mais científica possível, as tomadas de decisão que são necessárias. Dentre estas, uma das mais importantes é indicar regiões prioritárias para a conservação, já que por motivos óbvios não é possível preservar todos os ecossistemas por inteiro. Nesse contexto, recentemente sugeriu-se que a aplicação de princípios, teorias e análises provenientes da biogeografia e da macroecologia seriam importantes na Biologia da Conservação, formalizando uma abordagem que tem sido denominada “Biogeografia da Conservação”. Assim, o objetivo deste artigo é discutir e revisar esses componentes da biogeografia da conservação, utilizando uma abordagem macroecológica para desenvolver e aplicar métodos de planejamento sistemático em conservação, utilizando o bioma Cerrado como um modelo de estudo. Foram discutidos inicialmente os padrões de riqueza e diversidade beta e, em um segundo momento, como esses padrões podem ser correlacionados à ocupação humana do Bioma. Essa relação é fundamental para subsidiar a aplicação de modelos de planejamento sistemático de conservação em escala regional (análises de insubstituibilidade, complementaridade e de lacunas). É preciso considerar também que há sérias falhas de conhecimento sobre os padrões de biodiversidade na região e que a escolha de grupos indicadores pode ser importante para minimizar problemas gerados pela falta de conhecimento. Assim, essa abordagem é interessante em um cenário de grandes incertezas (ausência de dados detalhados) e de rápida transformação da paisagem, possibilitando a otimização de estudos em grandes escalas e depois transferir os resultados para escalas espaciais mais locais e realmente relevantes para a conservação. Nessas regiões, podem ser realizados, em um segundo momento, estudos mais detalhados a fim de avaliar padrões de viabilidade populacional, fragmentação de habitat e regiões potenciais de manutenção da diversidade genética

Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory

The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared to the data of the surface detector stations of the Observatory, which provide well-calibrated information on the cosmic-ray energies and arrival directions. The response of the radio stations in the 30 to 80 MHz regime has been thoroughly calibrated to enable the reconstruction of the incoming electric field. For the latter, the energy deposit per area is determined from the radio pulses at each observer position and is interpolated using a two-dimensional function that takes into account signal asymmetries due to interference between the geomagnetic and charge-excess emission components. The spatial integral over the signal distribution gives a direct measurement of the energy transferred from the primary cosmic ray into radio emission in the AERA frequency range. We measure 15.8 MeV of radiation energy for a 1 EeV air shower arriving perpendicularly to the geomagnetic field. This radiation energy -- corrected for geometrical effects -- is used as a cosmic-ray energy estimator. Performing an absolute energy calibration against the surface-detector information, we observe that this radio-energy estimator scales quadratically with the cosmic-ray energy as expected for coherent emission. We find an energy resolution of the radio reconstruction of 22% for the data set and 17% for a high-quality subset containing only events with at least five radio stations with signal.Comment: Replaced with published version.

Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy

We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Auger Observatory, we obtain a radiation energy of 15.8 \pm 0.7 (stat) \pm 6.7 (sys) MeV for cosmic rays with an energy of 1 EeV arriving perpendicularly to a geomagnetic field of 0.24 G, scaling quadratically with the cosmic-ray energy. A comparison with predictions from state-of-the-art first-principle calculations shows agreement with our measurement. The radiation energy provides direct access to the calorimetric energy in the electromagnetic cascade of extensive air showers. Comparison with our result thus allows the direct calibration of any cosmic-ray radio detector against the well-established energy scale of the Pierre Auger Observatory.Comment: Replaced with published version.

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

ATLANTIC-PRIMATES: a dataset of communities and occurrences of primates in the Atlantic Forests of South America

Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta. The dataset includes 700 primate communities, 8,121 single species occurrences and 714 estimates of primate population sizes, covering most natural forest types of the tropical and subtropical Atlantic Forest of Brazil, Paraguay and Argentina and some other biomes. On average, primate communities of the Atlantic Forest harbor 2 ± 1 species (range = 1–6). However, about 40% of primate communities contain only one species. Alouatta guariba (N = 2,188 records) and Sapajus nigritus (N = 1,127) were the species with the most records. Callicebus barbarabrownae (N = 35), Leontopithecus caissara (N = 38), and Sapajus libidinosus (N = 41) were the species with the least records. Recorded primate densities varied from 0.004 individuals/km 2 (Alouatta guariba at Fragmento do Bugre, Paraná, Brazil) to 400 individuals/km 2 (Alouatta caraya in Santiago, Rio Grande do Sul, Brazil). Our dataset reflects disparity between the numerous primate census conducted in the Atlantic Forest, in contrast to the scarcity of estimates of population sizes and densities. With these data, researchers can develop different macroecological and regional level studies, focusing on communities, populations, species co-occurrence and distribution patterns. Moreover, the data can also be used to assess the consequences of fragmentation, defaunation, and disease outbreaks on different ecological processes, such as trophic cascades, species invasion or extinction, and community dynamics.
