Internal devaluation and economic inequality in Portugal: challenges to industrial relations in times of crisis and recovery

Internal devaluation policies imposed in southern European countries since 2010 have weakened labour market institutions and intensified wage inequality and the falling wage share. The debate in the wake of the financial and economic crisis raised concerns about slow wage growth and per- sistent economic inequality. This article attempts to shed light on this debate, scrutinising the case of Portugal in the period 2010–2017. Mapping the broad developments at the national level, the article examines four sectors, looking in particular at the impact of minimum wages and collective bargaining on wage trends vis-a`-vis wage inequality and wage share trajectories. We conclude that both minimum wage increases and the slight recovery of collective bargaining had a positive effect on wage outcomes and were important in reducing wage inequality. The extent of this reduction was limited, however, by uneven sectoral recovery dynamics and the persistent effects of pre- carious work, combined with critical liberalisation reforms.info:eu-repo/semantics/acceptedVersio

Mimosoideae (Leguminosae) importantes para o manejo florestal no estado do Pará.

Leguminosae está representada por três subfamílias, 727 gêneros e 19.325 espécies, com distribuição cosmopolita. Mimosoideae possui cerca de 3.270 espécies circunscritas em quatro tribos, com 78 gêneros. Devido à ampla distribuição geográfica das Leguminosae na Amazônia e ao potencial econômico apresentado por diversas espécies, o estudo dessa família torna-se muito importante para a região. O presente trabalho teve como objetivo listar as espécies de Mimosoideae importantes para o manejo florestal no Pará e indicar suas respectivas áreas de ocorrência nesse Estado, visando contribuir para planos de manejo regionais. Inicialmente, preparou-se uma lista das Mimosoideae comercializadas no Pará, a qual foi baseada na lista oficial da SEMA (Secretaria de Estado de Meio Ambiente - PA) inerente às espécies produtoras de madeireira, complementada pela lista do IBAMA e de algumas madeireiras do Estado e das amostras de madeira que chegam à Xiloteca da Embrapa Amazônia Oriental. Os herbários IAN, INPA, MG, RB e RON foram consultados a fim de obter informações sobre local de coleta das espécies da lista. Todas essas informações foram incorporadas em um banco de dados; também estão sendo incluídas as coordenadas geográficas dos respectivos locais de coleta. A lista de espécies de Mimosoideae importantes para o manejo florestal no Pará corresponde a 40 espécies circunscritas em 16 gêneros, as quais se encontram registrados em 2.228 exemplares nos herbários consultados

Knowledge Acquisition by Networks of Interacting Agents in the Presence of Observation Errors

In this work we investigate knowledge acquisition as performed by multiple agents interacting as they infer, under the presence of observation errors, respective models of a complex system. We focus the specific case in which, at each time step, each agent takes into account its current observation as well as the average of the models of its neighbors. The agents are connected by a network of interaction of Erd\H{o}s-Renyi or Barabasi-Albert type. First we investigate situations in which one of the agents has a different probability of observation error (higher or lower). It is shown that the influence of this special agent over the quality of the models inferred by the rest of the network can be substantial, varying linearly with the respective degree of the agent with different estimation error. In case the degree of this agent is taken as a respective fitness parameter, the effect of the different estimation error is even more pronounced, becoming superlinear. To complement our analysis, we provide the analytical solution of the overall behavior of the system. We also investigate the knowledge acquisition dynamic when the agents are grouped into communities. We verify that the inclusion of edges between agents (within a community) having higher probability of observation error promotes the loss of quality in the estimation of the agents in the other communities.Comment: 10 pages, 7 figures.

Dimorphandra gardneriana Tulasne (Fava d’anta) - Uma abordagem etnobotânica e riscos de extinção

Dimorphandra gardneriana Tulasne (Legumimosae), popularly known as fava d’anta, is a plant widely distributed in the Brazilian Cerrado, occurring in the Chapada do Araripe, located in the South of the state of Ceara. Its fruits are exploited to obtain rutin and quercetin, both are bioflavonoids with several pharmacological activities studied. The extraction of D. gardneriana is an important source of income, especially for residents of communities surrounding the extraction region of the Chapada do Araripe. However, uncontrolled extraction threatens this species to extinction. Given the above, actions like the development of sustainable sampling techniques, or studies in genetics should be implemented to ensure the conservation of this species.Dimorphandra gardneriana Tulasne (Leguminosae), popularmente conhecida como fava d’anta, é uma planta de ampla distribuição no Cerrado Brasileiro, com ocorrência na Chapada do Araripe, situada no sul do estado do Ceará. Os seus frutos são explorados para obtenção de rutina e quercetina, ambos flavonóides com diversas atividades farmacológicas estudadas. O extrativismo de D. gardneriana é uma importante fonte de renda, principalmente, para as comunidades extrativistas residentes do entorno da Região da Chapada do Araripe. No entanto, o extrativismo desenfreado tem ameaçado essa espécie ao risco de extinção. Diante do exposto, ações como o desenvolvimento de técnicas de coleta sustentáveis ou estudos na área da genética devem ser implementadas, afim de garantir a conservação dessa espécie

Effect of immunocastration and caponization on fatty acid composition of male chicken meat

Research Areas: AgricultureAiticle in International JournalABSTRACT - Recently, immunocastration with Improvac (ImmC). has been tested in broilers and a considerable reduction in serum testosterone concentration (reduced by 79% compared to roosters) was observed. The aim of this study was to evaluate the effect of immunocastration on meat fatty acid (FA) composition and its comparison with caponized and intact males (roosters). The study was conducted with 3 experimental groups: control group (roosters), the group of birds submitted to surgical caponization (SurgC), and the group of birds submitted to immunocastration with Improvac. The comparison of breast meat partial FA sums of castrated (SurgC and ImmC) with control birds (roosters) revealed that castrated birds showed significantly higher content of n-3 polyunsaturated fatty acids (n-3 PUFA) than control birds (1.76 vs. 1.46 g/100 g of total FA; superiority of 20.2%), which has contributed to the occurrence of significant differences on both the n-6/n-3 ratio and the atherogenicity index (AI). In contrast, on leg meat portion, castrated birds displayed higher contents of both total saturated and monounsaturated fatty acids (SFA and MUFA, with 2.2 and 4.1% more, respectively) and lower total n-6 PUFA content (8.3% less) than was observed in control birds, which contributed to significant differences in the AI index. On the other hand, the comparison of breast meat portion from SurgC with ImmC showed that immunocastration contributed to lower total SFA and higher total n-6 PUFA, which have contributed to significant differences on both Polyunsaturated/Saturated (P/S) and n-6/n-3 ratios. Whereas, on leg meat portion no significant differences were observed on partial sums and a single difference was observed on the thrombogenicity index. Immunocastration of broilers has contributed to minor changes in the FA profile, but has improved the overall lipid quality indexes in both breast and leg meat portions. Therefore, immunocastration could be applied as an alternative method to caponization without negative consequences in meat FA profile.info:eu-repo/semantics/publishedVersio

Sistemas agroflorestais agroecológicos em Rondônia: classes de solos e crescimento de espécies florestais.

Sistemas agroflorestais são associações de cultivos anuais com espécies florestais e em alguns casos pastagens e/ou animais, escalonados no tempo e no espaço. Este trabalho teve por objetivo caracterizar alguns sistemas agroflorestais agroecológicos em Rondônia do ponto de vista da classe de solo e crescimento de espécies florestais. Foram visitados 24 sistemas em seis municípios, as áreas georeferenciadas, elaborado mapa de classe de solos e avaliados crescimento em altura e DAP de espécies florestais. Foi verificado que apesar do nível de fertilidade do solo ser considerado suficiente em alguns locais, o crescimento das espécies foi prejudicado pelo espaçamento inadequado. Os sistemas estudados estão situados em sua maioria em Latossolo Vermelho Eutrófico, e apenas um em Cambissolo Háplico Distrófico
