Addressing global fisheries overexploitation requires better understanding of how small-scale fishing communities in developing countries limit access to fishing grounds. We analyze the performance of a system based on individual licenses and a common property-rights regime in their ability to generate incentives for self-governance and conservation of fishery resources. Using a qualitative before-after-control-impact approach, we compare two neighbouring fishing communities in the Gulf of California, Mexico. Both were initially governed by the same permit system, are situated in the same ecosystem, use similar harvesting technology, and have overharvested similar species. One community changed to a common property-right regime, enabling the emergence of access controls and avoiding overexploitation of benthic resources, while the other community, still relies on the permit system. We discuss the roles played by power, institutions, socio-historic, and biophysical factors to develop access controls. © 2012 The Author(s).

En este trabajo se presenta el resultado obtenido del análisis de un proceso de razonamiento inductivo desarrollado por 12 estudiantes de secundaria en un contexto de resolución de problemas. Se plantea un problema, en el transcurso de una entrevista, que consiste en determinar el número máximo de regiones que se obtienen al trazar rectas sobre un plano. Durante la resolución del problema los estudiantes, y a través del dialogo con el entrevistador, han de explicar y justificar sus decisiones. Centrándonos en el trabajo de Pólya y en otras investigaciones previas relacionadas sobre este tema, se define un sistema de categorías mediante las cuales se organizan los datos para su análisis.

New records of vascular plants from Sierra del Rincón Biosphere Reserve and surroundings (Spain, Madrid province) are provided. It is noteworthy the presence of atlantic flora in this continental area and the different shrubby communities in different sectors with different litology: in areas with gneiss they are dominated by leguminous genisteae; where it is schistous, shale or quartzite they are heathlands.

Se realiza una propuesta de división en subsectores del sector Setabense (Provincia biogeográfica Catalano- Valenciano-Provenzal). Las unidades reconocidas son: 1 subsector Valenciano;2 subseetor Enguerina-Cofrentino; 3 subsector Ayorano-Villenense; 4 subsector Alcoyano-Diánico. Para cada uno de ellos se aporta una breve descripción y caracterización de su flora, vegetación, paisaje vegetal, suelos, bioclimatología, usos del territorio, etc. Además se proponen dos nuevas combinaciones taxonómicas: Asperula paui Font Quer subsp. dianensis (Font Quer) de la Torre, Alcaraz & Crespo y Linaria depauperata Leresehe ex Lange subsp. hegelmaieri (Lange) de la Torre, Alcaraz & Crespo, y se valida la combinación Arctostaphyllos uva-ursi (L.) Sprengel subsp. crassifol¡a (Br.-Bl.) Rivas-Martínez ex de la Torre, Alcaraz & Crespo.

A syntaxonomic revision of the Iberian "espartales" -dry grasslands dominated by Stipa tenacissima L.- is reoprted. Nomenclatural types as well as floristic, ecologic, dynamic and biographic data (Stipion tenacissimae, Lygeo-Stipetalia, Lygeo Stipetea) is described for the thermophilous Alcoian espartales, and the name Heteropogono conforti-Stipeton tenacissimae is also validated for the thermophilous Valencian-Tarraconensian ones.

Studies on the flora and fauna of the Canary Islands show that this Archipelago is one of the planet’s diversity hot spots. However, an analysis of the differences in the phytogeographic characteristics of each of the islands that make up this Archipelago is lacking. This article focuses on the phytogeographic characterization of the island of Gran Canaria. This island exhibits geological and climatic characteristics resulting in a rich vascular flora, including endemic species and genera that are significantly different from the other islands of the Archipelago. These differences are verified through statistical analysis of the existing similarity between the floras of the members of the Canary Islands. This study also analyses the subdivision of Gran Canaria Island, indicating that there are three well-differentiated areas on the island itself. Finally, this study argues that these areas, themselves, should be considered biogeographic sectors.

Theatre is a cultural and artistic form that involves a process of communication between creators and is received in a space and time located in the public sphere, which has meant that, over the centuries, it has acted as a space for expression, exchange and debate regarding all manner of ideas, causes and struggles. Implicit within this process are processes of expression, creation and reception, by way of which people demonstrate, analyse and question ways of seeing and understanding life, and ways of being and existing in the world. This gives rise to educational, cultural, social and political potential, which has been endorsed in numerous studies and investigations. In this work, in which theoretical orientation is established through a review of the relevant literature, we consider different intersections that occur between theatre and social work in order to also show that dramatic and theatrical expression offers substantive methodologies for achieving some objectives of social work, particularly in areas such as critical literacy, reflexivity and recognition, awareness raising, social participation, personal and/or community development, ownership of cultural capital and access to personal and social wellbeing.

The aim of this paper is to show that only in a society where human rights are honored and democracy is vigorous, the process of subjectivation be possible. It is a critical sociology research. The article is presented in two parts, the first, subject and subjectivity in contemporary times, analyze the obstacles that individuals have for subjective process, and the second, subject and human rights and subject and democracy we argue about the need for human rights and democracy for the process of subjectivation.

The development of cultural policy analysis by social science has been produced a theorization about cultural policy models from sociology and political science. This analysis shows the influence of the national model of cultural policy on the forms of governance and management of cultural facilities. However, in this paper we will defend that currently the local model of cultural policy decisively influences the model of cultural institutions. This is explained by the growing importance of culture in local development strategies. In order to demonstrate this we will analyze the case of the Barcelona Model of local development and cultural policy, that is characterized for the level of local government leadership, multilevel governance, the use of culture in urban planning processes and a tendency to use public-private partnership in public management. This Model influences the genesis and development of the cultural facilities and it produces a singular and relatively successful model.

this paper is about EU “soft policies” on immigrant integration. It analyzes the “Common Basic Principles” (CBPs) and the “European Integration Fund” (EIF), two devices that have been recently established within this framework. It adopts the theoretical perspective of the “anthropology of policy” and “governmentality studies”. It shows the context of birth of the aforementioned devices, as well as their functioning and the assessment done by the actors implied in the elaboration/implementation/evaluation of the related policies. It is based both on documentary research as well as direct observation and interviews done to the actors implied. It concludes that the PBC and the EIF should be considered as a “technology of government”, that strives to align the conduct of the actors with the governmental aims, as well as it produces specific practices and knowledge. It also underlines an intrinsic feature of many policies: their “congenital failure”, since they are (often) disputed and resignified by situated actors, who are embedded in asymmetrical power relations.
