Efeitos do transporte e do tempo de espera no bem-estar e na qualidade de carne de cordeiros

Com este estudo objetivou-se avaliar os níveis de estresse e a qualidade de carne de cordeiros mestiços Santa Inês x Dorper, submetidos a transporte de percurso curto (duas horas) e longo (seis horas) e em dois períodos de espera pré-abate (12 ou 24 horas). Foram utilizados 32 cordeiros com 127 ± 7 dias de idade e 30,4 ± 2,1 kg de peso vivo. Antes de serem submetidos aos períodos de transporte, os animais estavam alocados em baias coletivas e receberam ração concentrada (farelo de soja e milho, calcário calcítico e núcleo com monensina), bagaço úmido de citros e capim Napier (Pennisetum purpureum) e água ad libitum. Foram realizadas avaliações de reatividade dos animais no momento do embarque, desembarque e durante a contenção dos animais para as colheitas de sangue, urina e temperatura ocular por termografia infravermelho. Durante o período de espera pré-abate, realizou-se a colheita de dados comportamentais dos animais. Foram avaliadas as concentrações de cortisol no soro, na urina e as concentrações de haptoglobina no soro nos períodos que antecederam a insensibilização, assim como no momento do abate. Os animais apresentaram baixa reatividade durante todos os manejos. Houve diferença significativa no comportamento dos cordeiros durante os períodos de espera (P < 0,05) que durante as 12 horas apresentaram frequência de comportamentos que indicaram bem-estar favorável, enquanto que o período de transporte não afetou (P > 0,05). Os níveis de cortisol no soro mantiveram-se semelhantes da saída dos animais para o transporte até o final do período de espera (P > 0,05), enquanto houve oscilação dessas concentrações no cortisol na urina (P < 0,05), com pico no desembarque dos animais de duas horas de transporte e diminuição ao final do período de descanso. Os níveis de haptoglobina mantiveram-se semelhantes da colheita realizada antes do transporte, no embarque e no desembarque (P > 0,05) e diminuíram no final do período de espera pré-abate (P < 0,05). A temperatura ocular elevou-se no embarque e no desembarque dos animais, com diminuição da temperatura ao final do período de espera (P < 0,05). No momento do abate, foi observado aumento das concentrações de haptoglobina (P < 0,05), enquanto não houve alteração nas concentrações de cortisol no soro (P > 0,05). Animais que permaneceram por 24 horas de espera pré-abate apresentaram maior força de cisalhamento e menor luminosidade (L*) e intensidade de amarelo (b*). As variáveis comportamentais foram pouco afetadas pelos períodos de transporte e de espera pré-abate, porém o período de 12 horas de espera favoreceu a qualidade da carne

Ofshoring de servicios en la economía española en el periodo 2000-2007

La literatura económica ha centrado la atención en el offshoring de servicios y en su efecto sobre el nivel de empleo nacional, unido a importantes críticas en relación al impacto negativo que esta estrategia provoca en términos de destrucción de empleos nacionales. En este trabajo se analiza la relevancia que tiene el offshoring de servicios en la economía española y, en concreto, en las ramas de servicios y se estudia su efecto sobre el nivel de empleo de este sector. El análisis empírico se lleva a cabo estimando una función de demanda de trabajo con elasticidad de sustitución constante (CES), incluyendo en la misma el efecto de offshoring. Este estudio se realiza para el periodo previo a la crisis, 2000-2007, a partir de los datos contenidos en las Tablas Input-Output de la Contabilidad Nacional del INE.

No effect of unemployment on intimate partner-related femicide during the financial crisis: a longitudinal ecological study in Spain

Background: Spain’s financial crisis has been characterized by an increase in unemployment. This increase could have produced an increase in deaths of women due to intimate partner-related femicides (IPF). This study aims to determine whether the increase in unemployment among both sexes in different regions in Spain is related to an increase in the rates of IPF during the current financial crisis period. Methods: An ecological longitudinal study was carried out in Spain’s 17 regions. Two study periods were defined: pre-crisis period (2005–2007) and crisis period (2008–2013). IPF rates adjusted by age and unemployment rates for men and women were calculated. We fitted multilevel linear regression models in which observations at level 1 were nested within regions according to a repeated measurements design. Results: Rates of unemployment have progressively increased in Spain, rising above 20 % from 2008 to 2013 in some regions. IPF rates decreased in some regions during crisis period with respect to pre-crisis period. The multilevel analysis does not support the existence of a significant relationship between the increase in unemployment in men and women and the decrease in IPF since 2008. Discussion: The increase in unemployment in men and women in Spain does not appear to have an effect on IPF. The results of the multilevel analysis discard the hypothesis that the increase in the rates of unemployment in women and men are related to an increase in IPF rates. Conclusions: The decline in IPF since 2008 might be interpreted as the result of exposure to other factors such as the lower frequency of divorces in recent years or the medium term effects of the integral protection measures of the law on gender violence that began in 2005.

Household debt and the European crisis. ECRI Research Report No. 13, June 2013

The fall in economic output all over Europe since 2008 has had important consequences for household liabilities. Major growth in demand and supply for household credit products has generated an increase in household debt, which contributed to growth rates during the pre-crisis period but – in some countries – became household-debt overhangs and helped inflate asset bubbles. In the run-up to the crisis, long-term economic lessons and theories were often overlooked and signs that the economic situation could worsen were ignored. Although not at the core of the crisis, household debt had important consequences for macroeconomic stability, robustness of growth and the depth of recessions. The last ten years in Europe have demonstrated the typical final stage of a household debt cycle: rapid increase and abrupt retrenchment. Widely varying outcomes across Europe enable us to consider the causes of the rapid growth in household debt and draw theoretical lessons that can help policy-makers and academics devise a coherent regulatory response to avoid extremes of the debt cycle in future.

ECB Policy and Eurozone Fragility: Was De Grauwe Right? CEPS Working Document No. 397, June 2014

Paul De Grauwe’s fragility hypothesis states that member countries of a monetary union such as the eurozone are highly vulnerable to a self-fulfilling mechanism by which the efforts of investors to avoid losses from default can end up triggering the very default they fear. The authors test this hypothesis by applying an eclectic methodology to a time window around Mario Draghi’s “whatever it takes” (to keep the eurozone on firm footing) pledge on 26 July 2012. This pledge was soon followed by the announcement of the Outright Monetary Transactions (OMT) programme (the prospective and conditional purchase by the European Central Bank of sovereign bonds of eurozone countries having difficulty issuing debt). The principal components of eurozone credit default swap spreads validate this choice of time frame. An event study reveals significant pre announcement contagion emanating from Spain to Italy, Belgium, France and Austria. Furthermore, time-series regression confirms frequent clusters of large shocks affecting the credit default swap spreads of the four eurozone countries but solely during the pre-announcement period. The findings of this report support the fragility hypothesis for the eurozone and endorse the Outright Monetary Transactions programme.

The Ukrainian government's strategy towards the opposition. OSW Commentary No. 47, 2011-09-02

In recent months in Ukraine, there has been a toughening of measures targeted at opposition leaders, in particular the former Prime Minister Yulia Tymoshenko and the former interior minister Yuri Lutsenko. These two have been charged with abuses of office when in power. The way in which the criminal investigations are being conducted shows that these measures are actually meant to prevent the two politicians from conducting regular political activities, or at least to make this practically impossible for them. These actions are an element of the Party of Regions’ long-term strategy, as it tries during the pre-election period to eliminate Yulia Tymoshenko from political life and weaken or even destroy her powerbase. Similar measures, although to a more limited extent, are being taken against other opposition groups. These actions are leading to the lowering of democratic standards in Ukraine, although these are still much higher than in Belarus or Russia; this has been proved, among other things, by the militia’s more restrained behaviour towards the protesters, and the fact that abuses of the law during the current investigations have not yet slipped into actual violations. The Ukrainian opposition is fragmented and disorganised; even the Yulia Tymoshenko Bloc is unable to stage a major campaign in defence of its leader. This allows the authorities to feel free to tighten their policy towards the opposition.

Dispute Settlement Alternatives in Future EU BITS. IES WORKING PAPER 1/2012

Following the inclusion of the Common Commercial Policy in the exclusive competences of the European Union, a handful of policy adjustments have occurred. Among these adjustments, investment protection has been a remarkable one - given its new, exclusive framework and an already established, state-level practice. As the new policy stands, Bilateral Investment Treaties, which had been negotiated and executed by the EU Member States in the pre-Lisbon period, can now only be negotiated and executed by the EU. These prospective ‘EU BITs’, inter alia, aim for an even stronger mechanism for the protection of investors both in the EU and in third states. A strong protection mechanism inevitably calls for a strong Dispute Settlement Mechanism, and the establishment of a DSM may prove to be challenging. The EU currently faces several questions on its path to a tangible and reliable ‘EU BIT’, and arguably the most outstanding one is the question of the DSMs to be incorporated in these new agreements. What are the alternatives of a DSM for these new BITs? Which alternatives are currently utilizable and which ones are not? What are the current problems that the EU face, and how can those problems be tackled? Is the International Centre for Settlement of Investment Disputes an alternative, and if not, why? Following a thorough overview, this paper aims to analyse the DSM alternatives for the EU to be used in the new EU BITs and ultimately provide a solid DSM proposal.

Filling the gap: open economy considerations for more reliable potential output estimates. Bruegel Working Paper 2015/11, October 2015

This paper argues that the Phillips curve relationship is not sufficient to trace back the output gap, because the effect of excess demand is not symmetric across tradeable and non-tradeable sectors. In the non-tradeable sector, excess demand creates excess employment and inflation via the Phillips curve, while in the tradeable sector much of the excess demand is absorbed by the trade balance. We set up an unobserved-components model including both a Phillips curve and a current account equation to estimate ‘sustainable output’ for 45 countries. Our estimates for many countries differ substantially from the potential output estimates of the European Commission, IMF and OECD. We assemble a comprehensive real-time dataset to estimate our model on data which was available in each year from 2004-15. Our model was able to identify correctly the sign of pre-crisis output gaps using real time data for countries such as the United States, Spain and Ireland, in contrast to the estimates of the three institutions, which estimated negative output gaps real-time, while their current estimates for the pre-crisis period suggest positive gaps. In the past five years the annual output gap estimate revisions of our model, the European Commission, IMF, OECD and the Hodrick-Prescott filter were broadly similar in the range of 0.5-1.0 percent of GDP for advanced countries. Such large revisions are worrisome, because the European fiscal framework can translate the imprecision in output gap estimates into poorly grounded fiscal policymaking in the EU.

What role for social investment in the new economic governance of the Eurozone? EPC Policy Brief, 10 November 2015

The EU, and the Eurozone in particular, has been going through a period of prolonged economic difficulty. While there are some signs of recovery, growth rates remain too low, only returning to the already modest growth rates of the pre-crisis period. This not only affects the creation of jobs, but also, through lower tax revenues and stagnant GDP levels, the consolidation of public finances.

Desempenho de longo prazo de IPOs no Brasil: um estudo para o período de 2004 a 2015

O objetivo deste trabalho é avaliar o desempenho de longo prazo das empresas que abrem o capital no Brasil. Os fenômenos de (1) valorização no primeiro dia de negócios pós-IPO (underpricing) seguido de (2) desempenho inferior ao mercado no longo prazo (long-run underperformance) foram amplamente documentados em trabalhos de outros autores. O foco do estudo está em verificar a persistência dessa baixa performance quando alongamos o período de avaliação para 5 anos. Adicionalmente, o estudo pretende entender que fatores são determinantes no desempenho destas ações no longo prazo. O trabalho analisa 128 IPOs ocorridos no período de 2004 a 2012 na Bovespa. Os resultados apontam para evidências estatisticamente significantes de underpricing. Este underpricing foi mais acentuado entre os anos de 2004 a 2008, período precursor da crise financeira do subprime. Quando se analisa a performance de longo prazo os resultados apontam que a carteira de IPOs apresentou performance abaixo do mercado até o 29° mês. Os IPOs lançados no período pré-crise do subprime tiveram performance abaixo do mercado após 3 anos, enquanto que os IPOs lançados no pós-crise tiveram retorno acima do mercado para 3 e 5 anos. Não foi identificada a persistência da baixa performance dos IPOs além do 29° mês. Três variáveis principais mostraram significância na explicação dos retornos de longo prazo: (1) o período de lançamento das ações, (2) o percentual de alocação de investidores estrangeiros, (3) e a reputação do coordenador da oferta. Os IPOs lançados no período pós-crise do subprime observaram melhor performance no longo prazo. Também apresentaram melhor performance os IPOs com maior presença de investidor estrangeiro. Adicionalmente, existe uma relação inversa entre a reputação do coordenador líder da oferta e a performance de longo prazo.

Tropical climate and vegetation simulations during the Heinrich event 1 using an Earth System Model of Intermediate Complexity (EMIC) - the University of Victoria Earth System-Climate Model (UVic ESCM)

Abrupt climate changes from 18 to 15 thousand years before present (kyr BP) associated with Heinrich Event 1 (HE1) had a strong impact on vegetation patterns not only at high latitudes of the Northern Hemisphere, but also in the tropical regions around the Atlantic Ocean. To gain a better understanding of the linkage between high and low latitudes, we used the University of Victoria (UVic) Earth System-Climate Model (ESCM) with dynamical vegetation and land surface components to simulate four scenarios of climate-vegetation interaction: the pre-industrial era, the Last Glacial Maximum (LGM), and a Heinrich-like event with two different climate backgrounds (interglacial and glacial). We calculated mega-biomes from the plant-functional types (PFTs) generated by the model to allow for a direct comparison between model results and palynological vegetation reconstructions. Our calculated mega-biomes for the pre-industrial period and the LGM corresponded well with biome reconstructions of the modern and LGM time slices, respectively, except that our pre-industrial simulation predicted the dominance of grassland in southern Europe and our LGM simulation resulted in more forest cover in tropical and sub-tropical South America. The HE1-like simulation with a glacial climate background produced sea-surface temperature patterns and enhanced inter-hemispheric thermal gradients in accordance with the "bipolar seesaw" hypothesis. We found that the cooling of the Northern Hemisphere caused a southward shift of those PFTs that are indicative of an increased desertification and a retreat of broadleaf forests in West Africa and northern South America. The mega-biomes from our HE1 simulation agreed well with paleovegetation data from tropical Africa and northern South America. Thus, according to our model-data comparison, the reconstructed vegetation changes for the tropical regions around the Atlantic Ocean were physically consistent with the remote effects of a Heinrich event under a glacial climate background.

Life history parameters and biocontrol potential of the mealybug parasitoid Coccidoxenoides peregrinus (Timberlake) (Hymenoptera: Encyrtidae): Asexuality, fecundity and ovipositional patterns

Properties relevant to the ovipositional activity and lifetime productivity of Coccidoxenoides peregrinus (Timberlake) were assessed in the laboratory, to determine the potential of this species as a biocontrol agent against the citrus mealybug, Planococcus citri (Risso). In general, this species has not performed well in orchards, except for a few localities on different continents. The mode of reproduction of C peregrinus is almost entirely thelytokous, with males produced sporadically and at low frequency. The females have both pro-ovigenic and synovigenic traits, which raises questions of the utility of this distinction. The females have a high reproductive potential with 10-20 eggs per day available within the first two days (after a short (12 h) pre-oviposition period), and 80-150 eggs per day thereafter until death at about eight days. Mean lifetime fecundity was 239.2 +/- 34.3 eggs. C peregrinus oviposits across a range of P. citri instars, but productivity relies predominantly on second instar hosts. Second stage (N2) hosts received most eggs in choice (about 52%) and no-choice (about 50%) tests. Most eggs deposited into N2 hosts (82%) reached adult stage whereas only a few of those deposited into N1 and N3 (about 5% each) developed successfully. The haemolymph of parasitised reproductive mealybugs contained granular structures and no parasitoid eggs were found 24 h after exposure to ovipositing wasps. Also, no wasps emerged from parasitised adult hosts that were kept alive. Parasitoid eggs deposited into adult hosts were presumed encapsulated and destroyed, as control mealybugs (not exposed to female wasps) had no granular structures in their haemolymph. Wasps exposed to an abundance of hosts soon started ovipositing, but only for a relatively short time each day (about 2.5 h out of a 7 h exposure). They stopped ovipositing despite eggs judged to be mature in their ovaries. The reproductive output of C peregrinus is discussed in relation to the ecological factors that could influence this output, and the implications for biocontrol are discussed. (C) 2003 Elsevier Inc.

A VIOLÊNCIA CONTRA AS MULHERES NA VIDA COTIDIANA Um estudo do Livro da Aliança a partir de Êxodo 20,22-23,19

O espaço social subjacente à unidade literária de Êxodo 20,22-23,19 pressupõe uma sociedade agrária. Aparentemente é monótona, marcada por inúmeros conflitos sociais. O contexto social é de empobrecimento das famílias clânico-tribais israelitas. A nova economia se organiza em torno do santuário. Na pesquisa, há bastante consenso quanto à origem desta unidade literária conhecida como Livro da Aliança. É literatura jurídica de caráter religioso. Uma prescrição jurídica não precede as condições da realidade a que vai se referir, mas prescreve sobre as condições e situações já existentes. Na pesquisa clássica atual, encontram-se duas grandes correntes sobre a origem e a época desta literatura. Uma defende que o Livro da Aliança remonta à época pré-estatal, passagem do tribalismo para a monarquia; a outra argumenta que o Livro da Aliança, enquanto corpus codificado de leis, é um produto tardio , possivelmente surgido no final do século VIII ou início do século VII a.C. O Livro da Aliança é a base literária da presente pesquisa. Quanto à origem e à época do Livro da Aliança, sigo a corrente que defende ser o texto da época final do período tribal, anterior à monarquia. Esta época foi marcada por grandes mudanças econômicas: passagem de uma economia solidária de subsistência para uma economia de concentração do produto. A tese consiste em analisar a violência contra as mulheres, estruturada no discurso jurídico do Livro da Aliança. Busca-se desvendar os mecanismos que justificam e naturalizam as práticas de violência. O destaque é a violência contra as mulheres escravas, contra as filhas e, de modo especial, enfatizo as violências contra as mulheres feiticeiras. Evidencio três categorias de escravas prescritas no texto: as escravas domésticas, que sofrem violências físicas, podendo chegar até à morte debaixo do castigo da vara; as escravas temporárias, que têm seus olhos destruídos e os seus dentes quebrados; e as filhas que são vendidas como escravas. Sua sexualidade é transformada em mercadoria. Há filhas que são seduzidas, violadas e submetidas como mulher ao seu estuprador. O único grupo social descrito a partir da sua função pública são as feiticeiras. As violências são institucionais e sexistas. O patriarcado é o princípio organizador da sociedade. A característica do Livro da Aliança é marcadamente androcêntrica.(AU)

Do external funds yield lower returns? Recent evidence from East Asian economies

One of the central explanations of the recent Asian Crisis has been the problem of moral hazard as the source of over-investment and excessive external borrowing. There is however rather limited firm-level empirical evidence to characterise inefficient use of internal and external finances. Using a large firm-level panel data-set from four badly affected Asian countries, this paper compares the rates of return to various internal and external funds among firms with low and high debt financing (relative to equity) among financially constrained and other firms. Selectivity-corrected estimates obtained from random effects panel data model do suggest evidence of significantly lower rates of return to long-term debt, even among firms relying more on debt relative to equity in our sample. There is also evidence that average effective interest rates often significantly exceeded the average returns to long-term debt in the sample countries in the pre-crisis period. © 2006 Elsevier Inc.
