Previous issue date: 2015-07-14Over the past decade, scientific and policy circles throughout Europe have been debating about how to best create working landscapes that balance agricultural production and environmental conservation in an economically sustainable fashion. In this regard, multi-functional landscape strategies have been perceived as a powerful instrument to help the European Union achieve its sustainable development goals. In an attempt to put these ideas in place, past reforms to the Common Agricultural Policy (CAP), and more recently the CAP post-2013 reform, contain a set of environmental standards and objectives that aim to improve overall environmental sustainability of European farms. This study examines the current CAP environmental standards both from conservationist and rural development perspectives, seeking to identify whether such measures can most successfully foster the concept of multi-functionality. Through an analysis of the legislative history of the CAP reform process, as well as a review of the literature on the conceptual frameworks to multifunctional agriculture, and particularly exploring the role of institutions in driving environmentally sustainable farming systems across the EU, the research findings suggest that environmental objectives have only been partially integrated into the CAP, either because of their limited scope or their unsuccessful implementation. At the policy level, these findings question the effectiveness of EU policy efforts to use CAP subsidies as an instrument to deliver environmental goals and contribute to the multiple functions of agriculture. CAP environmental objectives have to a considerable degree remained fragmented, which reinforces the need to promote more integrative policy approaches as a way to explore the potentials of multifunctional agriculture in all its complexity, and to achieve broader sustainability and rural development goals

Antennae light brown, antennomeres 1–2 longer than the others, the latter subpyriform, the third and the fourth are the shortest ones and subpyriforms, antennomeres 5–10 gradually longer and oval-shaped, the last one acuminate. Mouth-parts (Fig. 4 b) show the general pattern of the genus. Pronotum cordiform (Fig. 4 c), transverse, about 1.2–1.3 times wider than long [length: 0.35–0.43 mm (males), 0.34–0.41 mm (females); width: 0.43–0.51 mm (males), 0.42–0.50 mm (females)]; anterior angles not produced, widely rounded off, lateral channel not recurved inside of anterior angles; disk slightly convex, depressed between the two basal pits, with a superficial central sulcus which does not reach the anterior margin; anterior margin slightly straight and posterior margin slightly arcuate outwards; lateral margins with two or three slight denticles just before the posterior angles, which are right and dentate. Vestiture (pubescence): surface covered with scattered erect pubescence; one seta on the lateral margin in the broadest part of the pronotum, another one near the posterior angle; two additional setae inserted near the anterior angles. Elytra (Figs. 4 d– 4 e) 1.7–1.8 times longer than wide [length: 0.96–1.12 mm (males), 0.94–1.08 mm (females), width: 0.54–0.63 mm (males and females)], slightly convex, parallel and oval posteriorly, with vestigial traces of striae. Tegument microsculptured, disk more punctured in the shoulders, punctures sparser and disappearing to apex (Figs. 4 d– 4 f); lateral margin narrow, finely serrate from the humeral angles, which are rounded, to the seventh seta of the umbilicate series. Vestiture: part of the pubescence of the disk is arranged in six irregular lines, these setae are erect and slightly directed anteriad (Fig. 4 e); umbilicate series follows the pattern of the genus. The longest setae of this series are the 2 nd, the 6 th and the 9 th with the 3 rd, 5 th, 7 th and 8 th, more slightly inserted within the elytral margin; besides these setae there are one parascutellar basad, two discal (one anterior and one posterior) and one apical seta (Figs 4 d– 4 f). Last abdominal ventrite with one pair of medium sub-marginal setae in males, two pairs of medium sub-marginal setae in females (Figs 4 g– 4 h). Male legs with the protarsomere 1 dilated; tarsomere 1 in all legs more pigmented (light brown) than the others; mesotibiae with a strong pubescence on both margins; hind femora (males and females) without any median tooth on the internal margin (Figs. 4 g– 4 h). Male genitalia (Figs 5 c– 5 d) with median lobe arcuate (lateral view), apex strongly sharp and bent down (lateral view), arcuate inwards in the right side and broadly rounded in the left side (dorsal view); basal lobe with apophysis prominent, basal edge arcuate; internal sac as in figures 5 c– 5 d; left and right parameres with 2 apical setae, left paramere with dorso-basal edge expanded (Fig. 5 c). The female genitalia follows the general pattern described for the other species of the genus (e.g., Zaballos & Jeanne 1987, Zaballos 1998, Zaballos, 2005). Female genitalia (Fig. 6 b) shows the gonocoxite IX sickle-shaped, and has a long ensiform seta in the middle region of the external margin, one ensiform seta in the middle dorsal region and a double nematiform seta in the internal margin near the beginning of the apical third. Gonosubcoxite IX without special features; laterotergite IX with a variable number of setae (8–10). Internal genitalia (not shown) with spermathecal duct long, parallel and enlarged very slightly near the bursa copulatrix (length: 0.16 mm), a spherical spermatheca (width: 0.019 mm), duct of spermathecal gland short and thin, gland fusiform (lenght: 0.096 mm), middle region membranous, apical portion sclerotized. Etymology. This new species is dedicated to the Portuguese naturalist Anthero Frederico Ferreira de Seabra, who greatly contributed to the knowledge of the Coleoptera of Portugal in the first half of the XX century. Morphological affinities. The two new species share with most species of Geocharis two setae on the elytral disk, one anterior and one posterior (Table 1). In Table 1 some other morphological characters like the presence or absence of elytral striae, a tooth on the internal margin of the hind femora and the number of setae of the left paramere are compared in all species of Geocharis. Taking into account the presence on the elytral disk of two setae, the absence of a tooth on the internal margin of the hind femora of males and females, as well as the fact that the adults present traces of elytral striae, the new species are close to G. b i v a r i Serrano & Aguiar, G. julianae Zaballos, G. k o r b i (Ganglbauer), G. massinissa (Dieck), G. montecristoi Zaballos and G. testatretafoveata Zaballos (all the adults of these species exhibit the above characters). Nevertheless, in G. b i v a r i and G. julianae the elytral striae are stronger than in the new species (see Zaballos 1989, Serrano & Aguiar 2004). Geocharis bivari, G. julianae and the remaining other four species are also easily segregated from the new ones by the shape of the median lobe of aedeagus plus the pattern of internal sac sclerites (Zaballos 1989, 2005, Serrano & Aguiar 2004 a). The new species are easily separated from one another by the aedeagus conformation (cf. Figs 5 a– 5 b and 5 c– 5 d) though they much resemble each other on external morphology. The growing knowledge of the genus Geocharis in terms of number of species and morphological peculiarities, corroborates former conclusions (e.g. Zaballos 2005) about the difficulty of identifying its species based only in the external morphology, with the exception of some taxa (see Table 1). Characters that are not mentioned in Table 1 like ovulate elytra and the presence of a vestigial sutural stria (G. coiffaiti and G. femoralis), left paramere features, the pronotum shape or even hind tibiae shape are useful for identifying particular Geocharis species. This happens with adults of G. leoni Zaballos which present the left paramere with lamellar and membranous scales in the apex instead of setae, the adults of G. portalegrensis which exhibit a pronotal disk strongly flattened, the adults of G. iborensis Zaballos which present the hind tibiae arcuate inwards instead of the general straight pattern, and the adults of G. julianae which present a fold in the internal margin of this structure (Zaballos 1989, 1990, 1998, Serrano & Aguiar 2000). Indeed, the best characters to identify and segregate the Geocharis species, besides the ones mentioned above, are found in the aedeagus, as are the general conformation of median lobe (lateral view), the apex of the same structure (dorsal view) and the armature pattern of the internal sac. Faunistic data on other Geocharis taxa and Hypotyphlus lusitanicus. Geocharis olisipensis Schatzmayr, 1937. Material examined: Bucelas (U.T.M. coordinates: 29 SMD 9305), 3.III.2011, 53, 4 Ƥ, 22.III.2011, 13, 2 Ƥ, 30.III.2011, 23, 1 Ƥ. Within the genus Geocharis this species was the first one described for Portugal based on two specimens collected near Lisbon (Schatzmayr 1937). Serrano & Aguiar (2004 a) after some efforts to locate this species found it in the outskirts of Lisbon (Valejas and Fanhões) and more recently in Serra de Montejunto (almost 50 km north of Lisbon) (Serrano & Aguiar 2008). The new locality near Bucelas is close to the former ones (Fig. 7). Geocharis quartaui Serrano & Aguiar, 2004. Material examined: Serra de Sicó (Pombal) (U.T.M. coordinates: 29 SNE 3319), 31.III.2008, 1Ƥ, 15.IV.2008, 13, 3 Ƥ; Serra do Sicó (Pombal) (U.T.M. coordinates: 29 SNE 3419), 15.IV.2008, 23 3, 10 Ƥ. This species was described on the basis of several specimens collected near Alcobaça (Carvalhal), a locality close to Serra de Aire e Candeeiros and recorded later in Serra de Montejunto (Serrano & Aguiar 2008). This new localization in Serra do Sicó (almost 40 km north of Serra de Montejunto), indicates for this species a wider distribution than the previously thought (Fig. 7). Interesting also is the fact that the Serra de Sicó male specimens exhibit a stronger median tooth on the internal margin of the hind femora than that observed in specimens of the other localities. Hypotyphlus lusitanicus Serrano & Aguiar, 2004. Material examined: Aldeia do Catarredor (Serra da Lousã) (U.T.M. coordinates: 29 TNE 6636), 2.IV.2008, 2 3; Fundeira (Pampilhosa da Serra) (U.T.M. coordinates: 29 TNE 8731), 3.IV.2008, 4 3, 3 Ƥ; Silvares (Fundão) (U.T.M. coordinates: 29 TPE 1141), 4.IV.2008, 1 Ƥ; Folgosa (Peso da Régua) (U.T.M. coordinates: 29 TPF 1357), 29.IV.2009, 1 Ƥ. One male and 1 female from Fundeira are deposited in the collection of Vicente Ortuño; all the remaining specimens are deposited in the collection of the first author, Departamento de Biologia Animal (Faculdade de Ciências da Universidade de Lisboa). This remarkable species was found in the centre of Portugal (Aldeia do Mato near Tomar) (Serrano & Aguiar, 2004 b). Lately it was found in a new locality (Barragem do Cabril, Pedrógão Grande) almost 60 km farther north (Serrano & Aguiar 2008). The new localities notably increase east- and northwards the distribution of this species (Fig. 7). Ecological and geographical considerations. The two new species of Geocharis inhabit the endogean environment in the same way than other congeneric taxa. This means that they live in the soil, usually at different depths of the B-horizon. They are found under sunken stones laying at different depths, from superficial (epigean) to well-buried (edaphic or endogean) environments. Individuals of endogean carabids are more easily found close to the superficial horizon layers after heavy rains because then the soil reaches higher percentage of humidity (saturation or close to saturation), pushing the beetles upwards. References to this behaviour are not abundant (e.g. Zaballos 2005; Zaballos & Pérez-González 2011), though we sampled several specimens of G. sacarraoi Serrano & Aguiar and Typhlocharis passosi Serrano & Aguiar, 2005 after rain in these conditions. However, the soil horizons do not always present the same depth and many times the bed rock is closer to the epigean environment. In this case endogean individuals may occur for instance between plates of sunken schistose rocks (e.g. Fig. 2). Though only one species of Geocharis occurs at a given locality, there are some recorded exceptions (e.g. Zaballos 2005; Serrano & Aguiar 2001, 2006, 2008). Sometimes Geocharis species can also be syntopic with species of the genus Typhlocharis (e.g. Dieck 1869, Serrano & Aguiar 2008). To date, all the Geocharis species located north of Tejo River in Portugal were recorded from localities ranging between the Lisbon region and Serra de Aire e Candeeiros. Interestingly, despite several field surveys to the north of Tejo River, only those conducted in the western region north of Lisbon led to the discovery of Geocharis species until now. Geocharis quartaui (also collected in this study) was found in Serra de Sicó, a mountain also located in the western region. The finding of the two new species here reported from surveys near the Douro River and Vimioso has increased the distribution of this genus 240 km farther north of Serra de Sicó. Yet, more remarkable was the discovery of Hypotyphlus lusitanicus in Folgosa in syntopy with G. barcorabelo n.sp. The presence of the former species north and south of Serra da Estrela (Fig. 7) corroborates the hypothesis that H. lusitanicus is a zoogeographical relict of a lineage that once must have extended westward from the Lionigurian massif to the Lusitanian massif (Serrano & Aguiar 2004 b). Finally we would like point out that G. barcorabelo n. sp. and G. antheroi n.sp. were not found within the limits of any Natural Park or protected area and as such are not currently under any conservation protection. From the 20 Geocharis species known in Portugal (including the new ones) (Table 1), only 7 (G. b i v a r i, G. boieiroi, G. monfortensis, G. m o s c a t e l u s, G. portalegrensis, G. quartaui and G. rodriguesi) were recorded inside the geographical limits of a protected area.Published as part of Serrano, Artur R.

Uma fotografia da obra de Roberto Aguiar : possibilidades para pensar o direito sob outras lentes
No full textDissertação (mestrado)—Universidade de Brasília, Centro de Estudos Avançados Multidisciplinares, Programa de Pós-Graduação em Direitos Humanos e Cidadania, 2015.Esta dissertação apresenta um estudo sobre a obra de Roberto Aguiar, jurista e humanista brasileiro, com vistas a identificar as contribuições que o autor produziu sobre o que é o direito e sobre educação jurídica. Para alcançar esse objetivo, realizei uma pesquisa bibliográfica com o levantamento e análise das obras publicadas. Produzi também uma pesquisa empírica, através de entrevistas semi-estruturadas com o autor, com o objetivo de identificar as motivações políticas e subjetivas para a produção das obras bem como levantar aspectos biográficos que ensejaram seus escritos, o que possibilitou realizar uma cartografia do entrelaçamento entre sua atuação política e uma subjetividade artística na construção do seu pensamento comprometido com as questões sociais e sensível aos sentimentos humanos. Com isso, no primeiro capítulo, apresento o movimento da vida de Roberto Aguiar em sua obra bem como o seu lugar de fala, no caso, os movimentos de crítica ao direito no Brasil. No segundo capítulo, identifico a concepção de direito desenvolvida por ele, destacando as relações de poder e opressão que constituem o fenômeno jurídico assim como a dimensão ritualística e as possibilidades de um direito justo, comprometido com a dignidade humana. No terceiro capítulo apresento as contribuições do autor para pensar a educação jurídica, sendo destacados os questionamentos sobre as dimensões ideológicas e metodológicas assim como apresentados os caminhos apontados por Aguiar: a criticidade, a interdisciplinaridade e a regionalização. Dessa forma, componho uma fotografia do pensamento de Roberto Aguiar que possibilita pensar o direito sob lentes da justiça, da sensibilidade e da alteridade.This dissertation presents a study about the work of Roberto Aguiar, jurist and brazilian humanist, in order to identify the contributions that the author has produced about what is law and on legal education. To achieve this goal, I conducted a literature search with the selection and analysis of published works. Also produced an empirical research through semistructured interviews with the author in order to identify political and subjective motivations for the production of works, also looking for biographical aspects that gave rise to his writings, which allowed actualize a mapping of entanglement between his political activities and an artistic subjectivity in the construction of his thought committed to social and sensitive to human feelings issues. Thus, in the first chapter, I present the motion of Roberto Aguiar’s life in his work and his place of speech, in this case the critical moves to the law in Brazil. In the second chapter, I identify the conception of law developed by him, highlighting the relations of power and oppression that constitute the legal phenomenon as well as the ritualistic dimension and the possibility of a fair law, committed to human dignity. In the third chapter I present the contributions of the author to think legal education, distinguishing the questions about the ideological and methodological dimensions just like presented and presented the paths appointed by Aguiar: criticality, interdisciplinarity and regionalization. Thus, I compose a picture of the thought of Roberto Aguiar that enables think the law under the lens of justice, sensibility and otherness.Centro de Estudos Avançados Multidisciplinares (CEAM)Programa de Pós-Graduação em Direitos Humanos e Cidadani
Home Cooking, Food Consumption and Food Production among the Unemployed and Retired Households
No full textUtilizing the 1996 Canadian Food Expenditure survey matched with Canadian Nutrient File, we separate actual food consumption from observed expenditure and test the Permanent Income/Life Cycle Hypothesis on the true consumption data. We find that the lower food expenditure during periods of unemployment or retirement (previously reported in the literature), does not translate into poorer nutrition. Household calorie intake and major nutrient intake seem to be unaffected by changes in employment status. We find evidence that unemployed or retired households substitute food purchased from restaurants for food purchased for at home consumption. Further, with the 1998 Time Use Survey we find that individuals who are not employed devote more time for food preparation. Finally we present limited evidence that unemployed and retired households substitute precooked meals for meals made from primary ingredients.Food Production, Nutrition, Consumption Smoothing
A (in)existência de Presunção de Esforço comum na aplicação da Súmula 377 do STF : um estudo da evolução jurisprudencial dos Tribunais Superiores
No full textTrabalho de Conclusão de Curso (graduação) — Universidade de Brasília, Faculdade de Direito, 2021.O presente estudo objetivou esclarecer o entendimento dos Tribunais Superiores acerca da necessidade de comprovação do esforço comum para partilha dos aquestos no regime de separação legal de bens, com base na interpretação dada à súmula 377 do Supremo Tribunal Federal (STF). Ao longo da pesquisa, buscou-se analisar as decisões do STF que deram origem à Súmula 377 do STF, as principais mudanças trazidas pelo Código Civil de 2002 no tratamento legal dado ao regime de separação legal de bens, bem como a evolução jurisprudencial do STJ e STF. Para a coleta de dados, utilizou-se como método a revisão de literatura e pesquisa jurisprudencial, centrado nos Tribunais Superiores, produzido em dois momentos: durante a vigência do Código Civil de 1916 e no período compreendido entre a promulgação do Código Civil de 2002 e o julgamento do EREsp 1.623.858/MG, em 23 de maio de 2018. Ao final, concluiu-se que, segundo jurisprudência consolidada do STJ, no regime de separação obrigatória de bens, comunicam-se aqueles havidos na constância da sociedade conjugal, desde que comprovado o esforço comum em sua aquisição.This study aimed to clarify the understanding of the Superior Courts about the need to prove that both spouses contributed in the acquisition of goods so as to share the assets under the compulsory separation of property system, based on the interpretation given to summary 377 of the Federal Supreme Court (STF). Throughout the research, we sought to analyze the STF decisions that gave rise to STF Precedent 377, the main changes brought by the Civil Code of 2002 in the legal treatment given to the legal separation of property regime, as well as the jurisprudential evolution of the STJ and STF. For data collection, bibliographic research was used as a method, through the study of the doctrinal and jurisprudential collection, centered on the Superior Courts, produced in two moments: during the validity of the Civil Code of 1916 and in the period between the enactment of the Code Civil of 2002 and the trial of EREsp 1,623.858/MG, on May 23, 2018. At the end, it was concluded that, according to the STJ's consolidated jurisprudence, under the mandatory separation of property regime, those acquired during marriage might become common goods, as long as the common effort in its acquisition is proven

No full textThe computational image analysis associated with the Mask R-CNN (Mask Region-based Convolutional Neural Network) can be used to automate and improve several routine evaluations, such as the tetrazolium test and seed purity analysis. The tetrazolium test is considered one of the fastest tests in the evaluation of seed viability, being highly dependent on the experience and ability of the evaluator to classify the results, thus being a subjective test. The analysis of physical purity is a mandatory determination for commercialization of seeds and indicates the physical quality of lots. Thus, the objective was to verify the efficiency of computational automation in the analysis of the tetrazolium and physical purity tests of Urochloa brizantha cv. Marandu through the Mask R-CNN. The experiment was conducted in Montes Claros. Batches of Brachiaria seeds from commercial locations were used. To obtain the images, in both tests, a flatbed scanner (Hp Officejet 4500 Desktop) was used. The tetrazolium test was performed according to the Seed Analysis Rules (0.1% solution, for 5 hours, at 40 ºC) (BRASIL, 2009). Each of the two fragments of the seeds was placed on the scanner glass plate with the colored part facing downwards. To automate the classification of the results of the tetrazolium test, 4 repetitions per lot were used and each repetition had 50 seeds. As for the automation of the purity analysis, 5 purity proportions were scanned, each proportion having two samples of 10 grams each. The neural networks showed high efficiency when classifying the results of the tetrazolium test, presenting accuracy values above 80%, and general accuracy around 91%. It also obtained efficiency in the estimation of the physical purity of the evaluated lots, with high coefficients of determination. Therefore, the automation of the analysis of tetrazolium tests and purity analysis in seeds of Urochloa brizantha cv. Marandu is viable using the Mask R-CNN technique.A análise computacional de imagens associada à Mask R-CNN (Mask Region-based Convolutional Neural Network) pode ser utilizada para automação e aprimoramento de diversas avaliações rotineiras, como o teste de tetrazólio e análise de pureza de sementes. O teste de tetrazólio é considerado um dos testes mais rápidos na avaliação de viabilidade de sementes, sendo altamente dependente da experiência e capacidade do avaliador para classificação dos resultados, sendo assim um teste subjetivo. A análise de pureza física é uma determinação obrigatória para comercialização de sementes e indica a qualidade física de lotes. Assim, objetivou-se verificar a eficiência da automação computacional na análise dos testes de tetrazólio e de pureza física de sementes de Urochloa brizantha cv. Marandu por meio do Mask R-CNN. O experimento foi conduzido em Montes Claros. Foram utilizados lotes de sementes de Brachiaria, provenientes de locais comerciais. Para obtenção das imagens, nos dois testes, foi utilizado um escâner de mesa (Hp Officejet 4500 Desktop). O teste de tetrazólio foi realizado de acordo com as Regras de Análises de Sementes (solução de 0,1%, por 5 horas, a 40 ºC)(BRASIL, 2009). Cada um dos dois fragmentos das sementes foi colocado sobre a placa de vidro do escâner com a parte corada voltada para baixo. Para automação da classificação dos resultados do teste de tetrazólio, foram utilizadas 4 repetições por lote e cada repetição possuiu 50 sementes. Já para a automação da análise de pureza foram escaneadas 5 proporções de pureza, sendo que cada proporção possuía duas amostras de 10 gramas cada uma. As redes neurais apresentaram alta eficiência ao classificar os resultados do teste de tetrazólio, apresentando valores de acurácia superiores a 80%, e acurácia geral em torno de 91%. Também obteve eficiência na estimação da pureza física dos lotes avaliados, com altos coeficientes de determinação. Logo, a automação da análise dos testes de tetrazólio e análise de pureza em sementes de Urochloa brizantha cv. Marandu é viável por meio da técnica Mask R-CNN.FAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superio
