New records of interesting xenophytes in the Iberian Peninsula

New records of interesting xenophytes in the Iberian Peninsula. Botanical inventories in various parts of Spain mainly between 2005 and 2007 yielded numerous chorological novelties.Cyperus prolifer is probably reported for the first time in Europe. Chenopodium simplex, Dactyloctenium aegyptium, Digitaria violascens, Eragrostis frankii, Ipomoea x leucantha, Ludwigia peploides subsp. montevidensis, Malvastrum coromandelianum, Melinis repens subsp. repens, Oenothera indecora subsp. indecora, Panicum philadelphicum subsp. gattingeri and Solanum americanum are probably recorded for the first time from Spain. Crassula campestris is first cited from Portugal. New provincial records include: Abutilon grandifolium (Barcelona), Amaranthus palmeri (Lérida), Amelichloa caudata (Valencia), Anoda cristata (Huelva), Arctotheca calendula (Gerona), Asparagus setaceus (Huelva), Bidens subalternans (Huelva), Cardiospermum halicacabum (Alicante), Cenchrus incertus (Cádiz), Cestrum parqui (Barcelona), Cyperus esculentus (Huelva), Datura ferox (Huelva), Elymus elongatus subsp. ponticus (Lérida, Sevilla), Eragrostis mexicana subsp.virescens (Huelva), Eragrostis pectinacea (Huelva), Galinsoga quadriradiata (Huelva), Hydrocotyle bonariensis (Huelva), Leptochloa uninervia (Granada, Huesca), Oenothera oehlkersi (Gerona), Rumex cristatus (Gerona), Senna obtusifolia (Huelva), Setaria faberi (Huelva), S. parviflora (Huelva), Solanum elaegnifolium (Alicante), S. linnaeanum (Granada), S. physalifolium (Huelva) and Verbena litoralis var. brevibracteata (Huelva). Previous Andalusian records of Galenia secunda turned out to be in error for G. pubescens. A large majority of the cited taxa is of American origin.Nuevas citas de xenófitos interesantes en la Península Ibérica.

Agro-food manufacturing in Mediterranean Spanish regions: Andalusia versus Valencian region

Agro ? food manufacturing is a basic activity in economic structure of Mediterranean regions. Spanish Mediterranean regions are not an exception in this pattern of specialization. Agro ? food manufacturing is very important in all the Spanish Mediterranean regions (Catalonia, Valencia, murcia and Andalusia). But there are some problems of reduced articulation of economic activities in southern Spanish Mediterranean regions that are not perceived in other Mediterranean spaces (Catalonia or Valencia). The aim of this article is to compare the different patterns of behavior of agro ? food manufacturing in two different Spanish Mediterranean regions: Andalusia and the Valencia community. Andalusia is a region that represents approximately 18% of Spanish population and territory. However, his participation in national g.d.p. is only of 12%. So, Andalusia is a region with some degree of backwardness in Spanish context. One of the rare activities where Andalusia has a participation of national average higher than his participation in population is agro food manufacturing. Andalusian agro food manufacturing represents 25% of total Spanish value added. Valencian community however is a richer regions and it has a more diversified manufacturing structure. The comparing between the two regions will allow to evaluate if the patterns of relation of agro ? food manufacturing with the rest of regional economic activities are similar in both region or there are important changes between them. This fact is very important for the design of a regional economic policy. Traditionally, the thesis of lack of economic articulation and orientation of economic activities toward other spaces has been defended in southern regions, especially in Andalusia. From this point of view, these elements decreased the possibilities of actuation of regional policies. However, agro ? food manufacturing, even in regions like Andalusia did not experience this kind of problems. In 1980 more of the 80% of the inputs used by this industry had regional origins. But in 1995 this participation was of the 63,3%. So there is a process of substitution of regional inputs for non-regional inputs even in activities with traditionally strong ties with regional productive structure, like agro ? food manufacturing. In this text, this hypothesis will be tested, comparing Andalusian situation with other regional situations a priori non-affected by this problem, like Valencian region. Input ? output tables of Andalusia and Valencian region will be employed to analyze this fact. The analysis will be carried for the agro ? food manufacturing and for different sectors included inside. It will be possible so to study with a relative high degree of detail the reality of agro ? food manufacturing in two concrete regions that, possibly, are representatives of a more general dynamic.

Urban Sprawl and Sustainable Urban Policies. A Review of the Cases of Lima, Mexico City and Santiago de Chile

In recent decades, urban processes have experienced deep transformations. One of them has been the growing importance of urban sprawl. This article reviews its main features and the policies related to the paradigm of sustainability in three Latin American Megalopolises: Mexico City, Lima, and Santiago de Chile. For this purpose, we have carried out an extensive compilation of the existing academic literature. Urban sprawl in those cities cannot be understood without considering the rising housing needs of popular classes, usually addressed through the sequence settlement-parceling-building-urbanization. Simultaneously high-income groups tend to create separated and gated commodities and there is increasing spatial mobility of the middle classes. Those processes tend to generate highly segregated and increasingly patched metropolitan areas. Sustainability is framed on models of urban governance based on ecological modernization. In this context, three main sustainable policies are analyzed: water supply, green areas provision, and transport. Conclusions stress: (1) Deep changes experienced and the path-dependent element observed in the social construction of sustainability (2) Consolidation of a model of socially segregated and ecologically differentiated urban polycentrism (3) Relevance of the different megalopolises as niches of experimentation and innovation in the construction of specific forms of sustainable transition

The Complex Domain Matrix of Ditransitive Constructions

This study focuses on the semantics of ditransitive constructions. Its main aim is to show that the semantics of this type of construction is made up of elements belonging to different conceptual domains. In order to fully analyze the complexity inherent in the semantics of this type of construction we draw on the concept of domain matrixes, proposed originally by Langacker. An analysis of different types of constructions shows that the matrixes are made up at the same time of elements from different domain types. It was also proven that a hierarchy or a difference in prominence can be identified among the domains that make up the matrix. This is so given that some of them are necessary to characterize the matrix of one type of construction whilst others are not. Given this observation, we propose the existence of basic domains and secondary domains in relation to their participation in the configuration of a ditransitive construction matrix

La Globalización financiera : empresas y estados

Este artículo analiza los procesos de globalización financiera desde una perspectiva histórica. De esta forma, se estudian sus orígenes, características y evolución en el pasado reciente. Esto proporciona un marco general en el que es posible situar los cambios en el comportamiento de empresas (fundamentalmente las grandes organizaciones) y los estados. De este modo, se pretende ilustrar cómo las formas de organización y gestión y las políticas tendentes a promover la competitividad han sufrido, en uno y otro caso, modificaciones muy importantes, como consecuencia de las transformaciones en la esfera de las finanzas internacionales. ________________________________________This article analyses financial globalisation processes from historical perspective. Origins, traits and evolution of financial globalisation are this principal argument. This study give a general framework to understand the changes in the behaviour of states and firms. Management, internal organisation and competitiveness policies have experienced important transformations, because the modification in international financial environment

Zur semantischen Basis der Numerusdistinktion im gesprochenen Portugiesisch Brasiliens

This paper examines the semantics of the singular/plural distinction in spoken Brazilian Portuguese. Analysis of real data from this variety of Portuguese shows that: 1) both plural marked NPs and plural unmarked NPs may have a plural reference; 2) the difference in plural marking is determined by semantic differences pertaining to the properties of (types of) plural objects denoted, respectively, by one or other construction. KEYWORDS: Semantics; Number; Brazilian Portuguese

Los regímenes monetarios con paridades irrevocablemente fijas: algunas reflexiones de la experiencia argentina

Recientemente, ha habido en distintas economías periféricas intentos por implantar sistemas cambiarios con paridades irrevocablemente fijas. Este artículo expone brevemente las ventajas y desventajas que, teóricamente, cabe esperar de los mismos. Con esta base teórica, se analiza el régimen cambiario argentino de los años noventa (conocido como currency-board). Se concluye que el fracaso final del mismo se debe más a los fundamentos teóricos del modelo que a los errores existentes en su gestión. En la parte final del artículo se profundiza en las bases sobre las que se asientan muchos de los errores observados.Many peripheral economies have developed irrevocably pegged monetary regimes in the last years. This article analyses the theoretical advantages and disadvantages of this kind of monetary regime. This theoretical base is used in the analysis of the Argentinean monetary regime (know as currency-board). It shall conclude that its final failure is due to the result of the theoretical foundations of the model, instead of mistakes in tits management. Some of the deep theoretical bases of the observed mistakes are analysed in the last part of this article

La economía vista desde un ángulo epistemológico: de la economía a la economía política; del estructuralismo a la complejidad

La ciencia económica es una ciencia diversa, con innumerables escuelas y corrientes. En el presente texto se ordenan algunas de ellas tomando una serie de criterios epistemológicos de referencia. De esta forma se distingue en primer lugar entre economía estándar y economía política y, posteriormente dentro de esta última entre aproximaciones estructuralistas y post-estructuralistas. Dentro de este último grupo de reivindica la necesidad de construir una economía política desde el paradigma de la complejida

La teoria de los actos de habla de W. P. Alston como fundamento para el desarrollo de uma semántica del diálogo

El presente artículo intenta sopesar la relevancia de algunos conocimientos adquiridos en el marco de un análisis del diálogo para la labor de descripción semántica. Se apuesta por un concepto multidimensional del significado que englobe tanto las cualidades lógico-semánticas atribuidas tradicionalmente a las expresiones lingüísticas, como las funciones desarrolladas por ellos para la estructuración del evento lingüístico como actividad de interacción social y sus consecuencias para la estructuración discursiva. Partiendo de las nociones semánticas presentadas por W. P. Alston en su teoría de los actos de habla se intenta tener en cuenta la cualidad dialógica de todo fenómeno semántico
