Análisis y clasificación de la vegetación leñosa de Galicia (España)

Después de los ensayos anteriores, de los que se hace un análisis histórico, de definir la diversidad de la vegetación gallega se propone una nueva ordenación basada en criterios actuales (florísticos, sucesionales, corológicos, respecto al Código de Nomenclatura Fitosociológica). El análisis se limita, en este caso, a las comunidades leñosas comprendidas en las clases Alnetea glutinosae, Calluno-Ulicetea, Cisto-Lavanduletea, Cytisetea scopario-striati, Pino-Juniperetea, Quercetea ilicis, Querco-Fagetea, Rhamno-Prunetea, Salicetea purpureae y Vaccinio-Piceetea, con un total de 65 asociaciones. Cada clase lleva una pequeña descripción que incluye su distribución en el territorio, las especies representativas y un comentario de sus afinidades con otras clases. Tras cada asociación aceptada se relacionan las tablas o grupos de inventarios gallegos que se asimilan a la misma con indicación del nombre originalmente osado y la referencia bibliográfica correspondiente.

Cavanilles 22: 358] and Junipero nanae-Sarothamnetum purgantis Rivas-Martínez 1963 [Anales Inst. Bot. Cavanilles 21(1): 172-186] respectively, was proposed and adopted.

Citizens’ attitudes toward public services. Satisfaction in 2009-2011

The aim of this paper is to study the recent changes on citizens’ satisfaction with the performance ofpublic services, in the period 2009-2011 in Spain. Using data from the surveys on Quality of PublicServices, developed by the Sociological Research Center jointly with the National Agency for theEvaluation of Public Services and Quality of Services, our results show that the level of satisfactionhas slightly increased, which seems to display a greater tendency to positively value public servicesduring economic retrenchment. A major determinant of high satisfaction is self-reported ideology.Besides, immigrants display higher levels of satisfaction than Spaniards.

Places making: participatory construction of scientifi c culture cities

In the framework of the European project Platform of Local Authorities and Communicators Engaged in Science (PLACES), we analyse the articulations between scientifi c communication, public perception of science, processes of citizen participation and apropiation of space, based on a case study of the inhabitants of Teruel city, Autonomous Community of Aragon, Spain. On the interrelationships between these issues, there are a number of contradictions, such as the difference between a high interest for information about science and technology and a low level of recognition and interaction with local institutions involved in those activities, the complex conceptualization of scientifi c space in relation to the “public-private” pair, or an articulation of a claiming civic rethoric and an insuffi cient co-responsibility. We conclude that, in a local context, the dimension of territoriality and, in particular, the identifi cation with the town, is a central mediation for activating citizen participation as part of processes of appropriation of space for setting up cities of scientifi c culture.

"Bobok" y "Pedro Páramo", dos narraciones sobre muertos

El presente estudio realiza un análisis comparativo entre la novela del mexicano Juan Rulfo, Pedro Páramo (1955), y un cuento del escritor ruso Dostoievski que trata también el tema del Más allá, titulado Bobok (1873). Paralelamente, se trabaja con la posibilidad de que el relato ruso hubiese podido ser una más de las fuentes literarias de la novela mexicana, y se trata de determinar las posibles conexiones -directas o indirectas- entre las dos obras. Ambas son puestas en común por su género literario, y a partir de ahí se estudian los elementos constitutivos que tienen en común, sus afinidades y divergencias más llamativas.

Paul Karl Feyerabend Las proyecciones de la proliferación teórica en la relación ciencia-metafísica

La doctrina de la Proliferación teórica de Paul Karl Feyerabend ha sido interpretada por sus especialistas como un intento de salvaguardar el ideal del progreso científico. Aunque tales estudios hacen justicia, en parte, a la intencionalidad de nuestro filósofo no explicitan la crítica fundamental que implica para Feyerabend el pluralismo teórico. La proliferación teórica constituye en sí misma una reductio ad absurdum de los distintos intentos del positivismo lógico y del racionalismo crítico por definir la ciencia a expensas de lo metafísico. Este artículo presenta la proliferación teórica como una reivindicación del papel positivo que ocupa la metafísica en el quehacer científico. Se consigna la defensa que hace Feyerabend de la metafísica en cuanto que ésta constituye la posibilidad de superar el conservadurismo conceptual, aumentar de contenido empírico de la ciencia y recuperar el valor descriptivo de las teorías científicas.

Panel Stationarity Test with Structural Breaks

In this paper, we extend the heterogeneous panel data stationarity test of Hadri [Econometrics Journal, Vol. 3 (2000) pp. 148–161] to the cases where breaks are taken into account. Four models with different patterns of breaks under the null hypothesis are specified. Two of the models have been already proposed by Carrion-i-Silvestre et al.[Econometrics Journal,Vol. 8 (2005) pp. 159–175]. The moments of the statistics corresponding to the four models are derived in closed form via characteristic functions.We also provide the exact moments of a modified statistic that do not asymptotically depend on the location of the break point under the null hypothesis. The cases where the break point is unknown are also considered. For the model with breaks in the level and no time trend and for the model with breaks in the level and in the time trend, Carrion-i-Silvestre et al. [Econometrics Journal, Vol. 8 (2005) pp. 159–175]showed that the number of breaks and their positions may be allowed to differ acrossindividuals for cases with known and unknown breaks. Their results can easily be extended to the proposed modified statistic. The asymptotic distributions of all the statistics proposed are derived under the null hypothesis and are shown to be normally distributed. We show by simulations that our suggested tests have in general good performance in finite samples except the modified test. In an empirical application to the consumer prices of 22 OECD countries during the period from 1953 to 2003, we found evidence of stationarity once a structural break and cross-sectional dependence are accommodated.

PANEL DATA UNIT ROOT TEST WITH FIXED TIME DIMENSION

The consideration of the limit theory in which T is fixed and N is allowed to go to infinity improves the finite-sample properties of the tests and avoids the imposition of the relative rates at which T and N go to infinity.

RNA polymerase I-specific subunits promote polymerase clustering to enhance the rRNA gene transcription cycle.

RNA polymerase I (Pol I) produces large ribosomal RNAs (rRNAs). In this study, we show that the Rpa49 and Rpa34 Pol I subunits, which do not have counterparts in Pol II and Pol III complexes, are functionally conserved using heterospecific complementation of the human and Schizosaccharomyces pombe orthologues in Saccharomyces cerevisiae. Deletion of RPA49 leads to the disappearance of nucleolar structure, but nucleolar assembly can be restored by decreasing ribosomal gene copy number from 190 to 25. Statistical analysis of Miller spreads in the absence of Rpa49 demonstrates a fourfold decrease in Pol I loading rate per gene and decreased contact between adjacent Pol I complexes. Therefore, the Rpa34 and Rpa49 Pol I–specific subunits are essential for nucleolar assembly and for the high polymerase loading rate associated with frequent contact between adjacent enzymes. Together our data suggest that localized rRNA production results in spatially constrained rRNA production, which is instrumental for nucleolar assembly.

Globalization, Police Reform and Development; Doing it the Western Way?

Under what conditions does successful police reform take place? Can democratic forms of policing exist within undemocratic state structures? What are the motives of donor and recipient nations, and can the norms of global civil society be cultivated in order to promote human rights, democratic governance, and fair and accountable policing? These questions are addressed in this volume, which presents a unique examination of Western-led police reform efforts by theoretically linking neoliberal globalization, police reform and development. The authors present seven country case studies based on this theoretical approach (Afghanistan, Brazil, Iraq, Northern Ireland, South Africa, Trinidad and Tobago, and Turkey) and assess the prospects for successful police reform in a global context.

Assessing the determinants of public confidence in the police: A case study of a post-conflict community in Northern Ireland

Drawing upon original survey research this article seeks to identify the generative processes that influence perceptions of the police in the context of an inner-city neighbourhood in Northern Ireland that has been affected by increases in crime and disorder in the aftermath of the peace process. Conceptually we draw upon recent research from England and Wales that outlines confidence in the police in terms of instrumental and expressive dimensions. We apply this framework and consider whether it provides a useful template for understanding the post-conflict dynamics of police-community relations in our study area. Contrary to much received wisdom our analysis suggests that instrumental concerns about crime and illegal activity are a more influential predictor of attitudes to the police than expressive concerns with disorder and anti-social behaviour. Consequently our discussion points to the variance in local and national survey data and questions the degree to which the latter can usefully inform our understanding of trends and developments in discrete micro-spaces. Our conclusion outlines the potential policy implications for state policing practice in deprived urban spaces.
