Política forestal y producción de los montes públicos españoles. Una visión de conjunto, 1861-1933
No full textEditada en la Fundación Empresa PúblicaUna de las consecuencias de las transformaciones de la propiedad de la tierra en España, durante el siglo XIX, fue la constitución de un extenso patrimonio forestal público (6,6 millones de hectáreas), que pasó a depender de la administración central y que se conserva hoy casi en su totalidad. En este artículo se ofrece una visión de conjunto de las producciones y de la gestión de los montes públicos. La intervención del Estado se ha dividido en cuatro etapas y, considerando los resultados más que los objetivos iniciales, destacan dos conclusiones. Primera: por sus características, los montes públicos no eran adecuados para que los gobiernos los utilizaran con el fin de dirigir el rumbo de la economía forestal nacional. Segunda: la administración central aplicó, no una, sino varias políticas forestales, atendiendo a los cambios en los mercados y a las diferentes circunstancias económicas, sociales y ecológicas de las comarcas donde se encontraban los montes.One of the consequences of transformations in Spanish land properties in the 19th century was the constitution of an extensive (6.6 million hectares) public forest patrimony —still kept— dependent on the Central Administration. In this article, an overview of the main features, as well as the management and production forms of such a patrimony, is presented. State intervention is divided into four stages and, considering their results rather than their initial goals, two main conclusions are reached. First, given their characteristics, public forests were not adequate for the government to be able to lead this part of the forest national economy. Second, the central administration applied not one but several public forest policies, according to changes in the markets and to the economic situation, and social and ecological conditions where forests were found.Publicad
Maria-Mercè Marçal: Short-Story Writer
No full textIn this article, Carme Riera talks about Marçal as a short-story writer, an aspect of the author which is less discussed than her poems and novels, but, according to Riera, not at all insignificant. She discusses the three short stories Marçal wrote for adults: Joc de màscares, El retorn and Tronatrons (unpublished). Riera refers to the game of intertextuality in Marçal’s work; Joc de màscares, which takes Riera’s novel, Te deix, amor, la mar com a penyora, as a starting point, and Tronatrons, which Riera feels could well be intended to pay a tribute to Víctor Català, whose work was well-known by Marçal. Finally, the author of this article talks about the importance of the recurring motif of the mirror in Marçal’s work, both in her poetry and novels
Estado, comunidad y mercado en los montes municipales extremeños (1855-1924)
No full textEditada en la Fundación Empresa PúblicaEste trabajo pretende evaluar el alcance de la intervención estatal en
el proceso de redefinición de los derechos de propiedad. El objetivo fundamental
es analizar, a través del estudio de los montes municipales extremeños,
el grado de aplicación de los dos mecanisnios de actuación previstos
por la legislación liberal en el ámbito de los patrimonios de titularidad pública:
la enajenación definitiva de la propiedad y la inspección técnica de la
producción. Aun matizando el protagonismo de la ley, la investigación confirma
plenamente el éxito de la fórmula privatizadora en el suroeste peninsular.
Menos evidente resulta, sin embargo, el triunfo de la vía interventora.
Es aquí, precisamente, donde quedan reflejadas las dificultades del Estado
para lograr una aplicación homogénea de la norma en todo el territorio
nacional.This work aims to evaluate the extent of State intervention in the process
of the redefinition of property rights. By studying the evolution of municipal
woodlands in Extremadura, my main objective is to analyse the two mechanisms
of intervention in the área of publicly held property: the definitive privatisation
of property and the technical inspection of production. Even if we
play down the effect of legislation, the present investigation confirms the full
success of the privatisation formula employed in the Sapnish Southwest. State
control over production, however, was far less efficient. Precisely in this área
we can see how difficult it is for the State to enforce a comprehensively policy
throghout its territory.Publicad

Adult male, 2.4 mm long, mounted on a slide (coordinates 28 º02´58 ´´N / 16 º 42´54 ´´W; 3 m depth) [DBAULL NE/TC 7 S 11]. Collected by R. Riera, November 2000. Collected by R. Riera, May 2000. Adult female, 1.6 mm long, mounted on a slide (coordinates 28 º02´58 ´´N / 16 º 42´54 ´´W; 3 m depth) [DBAULL NE/TC 7 S 12]. Collected by R. Riera, November 2000. Meristic data. Cristianos subtidal: May, 1 female (Allotype), November, 1 female (f 2), 2 males (Holotype and m 2). Etymology. The specific name refers to the triangular gubernaculum of this species. Description. Male: Body slender, attenuating towards both ends. Head round and slightly set off. Cuticle with very fine transverse striations, sometimes inconspicuous in the posterior half. Amphids are 68 % of the corresponding body diameter in width, consisting of 2.5 turns, located at 6 m from the anterior end. Buccal cavity conical and small, without noticeable teeth. Inner labial setae lacking. Six outer labial setae 2 m long and 4 cephalic setae 1.6 cephalic diameters long, situated on the anterior part of the head. Subcephalic setae 13 m long, numerous, arranged in 6–9 rows and located at 21–60 m from the anterior end. Pharynx narrow and cylindrical. Ventral gland and nerve ring not seen. The reproductive system is diorchic, with two opposed testes, almost inconspicuous. Spicules 1.7 anal diameters long, paired, arcuated and without marked capitulum. Gubernaculum 0.75 anal diameters long, with slender apophysis and distally compressed. 15 precloacal supplements 3 m wide, the posteriormost located at 21 m from the cloaca. Precloacal seta 7 m long, situated at 18 m from the cloaca. Tail 5.3 anal diameters long, cylindrical and with slightly swollen posterior tip. Subterminal setae 17 m long, located at 5 m from the posterior end. Caudal setae 25 m long. Spinneret conspicuous. Female: They are similar to males. Tail length slightly shorter than in males (3.2–4.5 anal diameters). The reproductive system is didelphic, with two opposed and reflexed ovaries. Vulva located in the anterior half of the body, at the level of 45.7 % of the total body length. Discussion. Setosabatieria triangularis new species most closely resembles S. fibulata (Wieser, 1954) in the shape of copulatory apparatus, but S. triangularis new species differs in having amphids 2.5 turns, occupying 68 % of the corresponding body diameter, while S. fibulata possess more developed amphids (90 % cbd), with 4.25 turns. S. triangularis new species can be distinguished from the remaining species of the genus: S. hilarula (De Man, 1922) and S. jingjingae (Guo & Warwick, 2001) in the number of amphid turns (3.25 in S. hilarula and 3.5 in S. jingjingae) and the size of the gubernaculum, very slender with a triangular apophysis in S. triangularis new species but narrower and slender in S. hilarula and S. jingjingae. Ecology. This species was recorded in Los Cristianos subtidal from fine sands (150– 180 µm, median particle size). The organic matter content ranged from 0.006 % to 1.01 % and 19.32–27.35 % carbonates.Published as part of Riera, Rodrigo, Núñez, Jorge & Brito, María Del Carmen, 2006, Two new species of Comesomatidae Filipjev, 1922 (Nematoda: Chromadorida) from sandy bottoms of Tenerife, Canary Islands, pp. 53-61 in Zootaxa 1126 on pages 58-60, DOI: 10.5281/zenodo.17183

Ocupação do solo e microclimas urbanos: o caso de Montes Claros - MG
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-graduação em Arquitetura e UrbanismoO trabalho se refere à análise do clima urbano de Montes Claros, cidade localizada no norte do estado de Minas Gerais, com cerca de 350 mil habitantes. O município possui o clima tropical sub-úmido, sendo definido por duas estações típicas: um verão quente com chuvas e uma estação seca prolongada. O trabalho parte do pressuposto de que há uma correlação entre as variáveis climáticas de temperatura e a umidade relativa (variáveis - resposta), medidas em campo, e as variáveis urbanísticas (variáveis explicativas) utilizadas no estudo que são: Proporção de Áreas Permeáveis e Impermeáveis, Densidade Construída, Fator de Forma e Fator de Visão de Céu e da análise qualitativa da topografia. Os dados climáticos foram medidos em onze pontos distintos da malha urbana, que representam diferentes padrões de uso do solo no município, em três períodos distintos: o verão quente e úmido, o inverno ameno e seco, e estação mais seca, com temperatura elevada e baixa umidade. Os resultados foram analisados sob três aspectos: através da análise causal e temporal da ilha de calor, através da correlação entre as variáveis e em relação à situação do conforto térmico exterior por meio do Diagrama Bioclimático de Givoni de 1992. Os resultados encontrados mostram elevada correlação entre os dados, especialmente no período noturno, estendendo-se até a madrugada, o que permitiu a identificação da ilha de calor na cidade como fenômeno noturno. Os resultados mostraram que há interdependência entre as variáveis, assim, conclui-se que o comportamento climático dos pontos não pode ser explicado por uma variável isoladamente. Contudo, correlações encontradas foram mais significativas para as variáveis de Densidade Construída, Fator de Forma e Fator de Visão de Céu. As correlações encontradas foram negativas para as áreas verdes e positivas para as áreas impermeáveis, em todos os períodos medidos. As variáveis levantadas se relacionam diretamente à legislação urbanística, e podem ser utilizadas como uma ferramenta para a incorporação dos dados do clima ao planejamento urbano do município. This work refers to the analysis of urban climate of Montes Claros, a city located in the north of Minas Gerais state in Brazil with about 350 mil inhabitants. The city's climate is sub-humid tropical, being defined by two typical seasons: warm summer with rain and prolonged dry season. This work assumes the presupposed that there is an intimate relation between temperature climate variables and relative humidity (answer variables), measured on the field, and urban variables (explicative variables) which are: Proportion of Permeable and Impermeable Areas, Constructed Density, Form Factor and Sky View Factor and Topographic Qualitative Analysis. The climate data was measured on eleven distinct points of the urban tissue, which represent different patterns of municipal ground use on three different periods: warm and humid summer; mild and dry winter; and drier season, with high temperatures and low humidity. The results were studied about three aspects: throught causal and temporal analysis of the urban heat island, through the correlation between variables and about thermal comfort through the Diagram Bioclimatic of Givoni 1992. The results show a high correlation between the data, especially during nighttime, extending through dawn, which allowed the identification of the heat island in the city as a nocturnal phenomenon. The results show that there is interdependence between the variables, then concluded that the conduct climate of points can not be explained by a variable alone. However, the correlations found were more significant in the Constructed Density, Form Factor and Sky View Factor. The correlations found were negative for green areas and positive for impermeable areas, during all measured periods. The found data relates directly to the urban legislation, which allows it to be used as a tool for incorporating data from the climate to the urban planning of the city
