Payments for environmental services in watersheds: insights from a comparative study of three cases in Central America

We have compared three cases of payments for water-related environmental services (PES) in Central America, in terms of socioeconomic background, opportunity costs of forest conservation and stakeholders’ perceptions on the conditions of water resources and other issues. We found that, in general, the foregone benefits from land uses alternative to forest cover are larger than the amount paid, which apparently contradicts the economic foundation of PES schemes. A number of possible explanations are explored. The results also suggest that trade-offs between different environmental and social goals are likely to emerge in PES schemes, posing some doubts on their ability to be multipurpose instruments for environmental improvement and rural development. We also found that PES schemes may work as a conflictresolution instrument, facilitating downstream -upstream problem solving, though at the same time they might introduce changes in social perceptions of property rights.

Rethinking economies: regulation and responsibility in contemporary ethnographic cases of production and exchange

Informe de investigación realizado a partir de una estancia en la University of London entre el 3 de marzo al 10 de abril 2007. Redacción de un artículo sobre aspectos metodológicos centrales para las ciencias sociales en su vertiente tanto teórica como aplicada: la articulación entre la investigación etnográfica y los modelos abstractos. Tanto la etnografía en sus múltiples formas de describir la realidad observable, como los modelos en su intento por reducir la complejidad con el fin de subrayar las conexiones causales son instrumentos de las ciencias sociales. Los modelos cambian el mundo: gracias a su cualidad abstracta pueden presentar no sólo una imagen de cómo funcionan las cosas, sino también subrayar el aspecto procesual de las conexiones permitiendo de este modo establecer proposiciones prospectivas y guiar las políticas públicas de desarrollo. En la base de la acción encontramos siempre alguna forma de modelización, incluso en el ámbito de las disposiciones subjetivas que mueven a la gente a la toma de decisiones cotidianas. A menudo la realidad escapa a la matriz de los modelos, sin embargo, y el cambio y la adaptación toman caminos insospechados y no planificados. Este proyecto busca construir la posibilidad de un diálogo constructivo, creativo y no-jerárquico entre los modelos de desarrollo económico y la etnografía(...)

Territorial autonomy and self-determination conflicts: opportunity and willingness cases from Bolivia, Niger, and Thailand

The paradox of autonomy is about whether self-rule accommodates or exacerbates armed conflict. This study attempts to unpack the puzzle examining the effectiveness of territorial autonomy as a state response to self-determination conflicts throughout the world. It challenges the conflict-inducing features of autonomy arguing that territorial autonomy can mitigate armed conflict by channeling group grievances into peaceful forms of protest. Thus, this study aims at arriving at a comprehensive theory that identifies which factors are responsible for violent escalation of conflicts grounded in self-determination demands. By using the concepts of opportunity structures and willingness dimension, this study shows that conflict escalation only takes place when minorities with greater bargaining power vis-à-vis the center, in contexts of high levels of economic inequality within dyad, are mobilized around autonomy and separatist demands.

The Barcelona Forum: on decentralized governance and conflict prevention 6-8 july 2009

The Barcelona Forum aimed to generate both a theoretical and practical discussion on decentralized governance and its capacity to promote peace, prevent conflict, advance human security and ensure greater governmental accountability. The Forum intended to review the theoretical strength of decentralization as a political tool and discuss how it can be properly implemented. Eight case studies were selected to be covered during the two days in order to draw conclusions and offer proposals for the future implementation of decentralization. The case of Catalonia and the decentralized experience of Spain was given special attention, as an example of successful decentralization. The other cases presented achievements and challenges and prompted discussions on both the validity and universality of decentralization as a way to promote and preserve peace. Topics such as ethnic and territorial divisions, democratic accountability, financial decentralization and distribution, resource sharing, and external implementation of decentralization through peace processes were discussed.

Expert supervision based on cases

The paper focuses on taking advantage of large amounts of data that are systematically stored in plants (by means of SCADA systems), but not exploited enough in order to achieve supervisory goals (fault detection, diagnosis and reconfiguration). The methodology of case base reasoning (CBR) is proposed to perform supervisory tasks in industrial processes by re-using the stored data. The goal is to take advantage of experiences, registered in a suitable structure as cam, avoiding the tedious task of knowledge acquisition and representation needed by other reasoning techniques as expert systems. An outlook of CBR terminology and basic concepts are presented. The adaptation of CBR in performing expert supervisory tasks, taking into account the particularities and difficulties derived from dynamic systems, is discussed. A special interest is focused in proposing a general case definition suitable for supervisory tasks. Finally, this structure and the whole methodology is tested in a application example for monitoring a real drier chamber

1954 les cases barates de Vila-roja : memòria d'una desaparició anunciada i les claus del seu valor històric

Estudi de les primeres 150 “cases barates”, o de tipus social que es van edificar al barri de Vila-roja entre el 1954 i el 1957, anomenades Grup “San Daniel”, i que varen representar l'inici d'aquest barri de Girona. L'estudi incideix en la gestació, en la transformació i en la desaparició progressiva de la fesomia inicial d'aquest barri de Girona projectat i dissenyat per l’arquitecte gironí Ignasi Bosch Reitg (1910-1985), que també fou l’arquitecte del Grup Sant Narcís, de Germans Sàbat i de Sant Cugat a Salt

X-chromosome tiling path array detection of copy number variants in patients with chromosome X-linked mental retardation

Background: Aproximately 5–10% of cases of mental retardation in males are due to copy number variations (CNV) on the X chromosome. Novel technologies, such as array comparative genomic hybridization (aCGH), may help to uncover cryptic rearrangements in X-linked mental retardation (XLMR) patients. We have constructed an X-chromosome tiling path array using bacterial artificial chromosomes (BACs) and validated it using samples with cytogenetically defined copy number changes. We have studied 54 patients with idiopathic mental retardation and 20 controls subjects. Results: Known genomic aberrations were reliably detected on the array and eight novel submicroscopic imbalances, likely causative for the mental retardation (MR) phenotype, were detected. Putatively pathogenic rearrangements included three deletions and five duplications (ranging between 82 kb to one Mb), all but two affecting genes previously known to be responsible for XLMR. Additionally, we describe different CNV regions with significant different frequencies in XLMR and control subjects (44% vs. 20%). Conclusion:This tiling path array of the human X chromosome has proven successful for the detection and characterization of known rearrangements and novel CNVs in XLMR patients.

Identity formation in social networks websites: facebook and the interaction between young individuals in the cases of Slovenia and Catalonia

This paper lays down some theoretical framework for further research to be made on the subject of how identity of young Slovenian and Catalan users is forming within the social networking website Facebook. The author pursues his interest based on observation of how communicationand thus interaction between users is changing and how this is reflected in everyday practices. In so doing he tries to identify the connections between the individual, society and technology, asthese are more and more interwoven, and we cannot think one without the other in thecontemporary globalised world.

Array-CGH in patients with a clinical diagnosis of Kabuki syndrome: identification of two cases with terminal 2q37 deletion and no other recurrent rearrangement

Background: Kabuki syndrome (KS) is a multiple congenital anomaly syndrome characterized by specific facial features, mild to moderate mental retardation, postnatal growth delay, skeletal abnormalities, and unusual dermatoglyphic patterns with prominent fingertip pads. A 3.5 Mb duplication at 8p23.1-p22 was once reported as a specific alteration in KS but has not been confirmed in other patients. The molecular basis of KS remains unknown. Methods: We have studied 16 Spanish patients with a clinical diagnosis of KS or KS-like to search for genomic imbalances using genome-wide array technologies. All putative rearrangements were confirmed by FISH, microsatellite markers and/or MLPA assays, which also determined whether the imbalance was de novo or inherited. Results: No duplication at 8p23.1-p22 was observed in our patients. We detected complex rearrangements involving 2q in two patients with Kabuki-like features: 1) a de novo inverted duplication of 11 Mb with a 4.5 Mb terminal deletion, and 2) a de novo 7.2 Mb-terminal deletion in a patient with an additional de novo 0.5 Mb interstitial deletion in 16p. Additional copy number variations (CNV), either inherited or reported in normal controls, were identified and interpreted as polymorphic variants. No specific CNV was significantly increased in the KS group. Conclusion: Our results further confirmed that genomic duplications of 8p23 region are not a common cause of KS and failed to detect other recurrent rearrangement causing this disorder. The detection of two patients with 2q37 deletions suggests that there is a phenotypic overlap between the two conditions, and screening this region in the Kabuki-like patients should be considered.

The cases of June 2000, November 2002 and September 2002 as examples of Mediterranean floods

Four flood events that affected three different countries are here described in terms of meteorological genesis and in terms of consequences on the population and on the territory. Each event is a good representative of a class of phenomena that produce important effects on the urban and extra-urban tissue and that must be taken into account in an optic of civil protection and risk evaluation. This is the subject of the HYDROPTIMET project, part of the Interreg IIIB program, which is collocated in the framework of the prevention of natural hazards and, in particular, those related to severe meteo-hydrological events. This paper aims at being a general introduction of the four events which are the subject of more detailed studies, already published or under submission.

Specific (granulomatous) oral lesions of sarcoidosis: Report of two cases

Sarcoidosis is a multisystemic granulomatous disease of unknown etiology that usually presents with bilateral hiliar adenopathies, pulmonary infiltrations, and ocular and cutaneous lesions. The specific cutaneous lesions, or granulomatous, are produced in from 9% to 37% of patients with systemic sarcoidosis. Nevertheless, few patients have been described having specific lesions from sarcoidosis in the oral mucous membrane. We present 2 patients with systemic sarcoidosis who developed specific sarcoidosis lesions in the oral mucous membrane. The first patient presented a plaque on the tongue of a chronic nature associated with facial lupus pernio. The second patient presented a rapidly growing nodular lesion on the lower lip that was in fact the presentation sign of the disease. Although infrequent, oral lesions may constitute the first sign of systemic sarcoidosis. For this reason the oral mucous membrane needs to be explored when there is suspicion of sarcoidosis, and systemic sarcoidosis must be included in the differential diagnosis of oral granulomatous lesions.

Majority carrier capture cross section determination in the large deep trap concentration cases

A method to determine the thermal cross section of a deep level from capacitance measurements is reported. The results enable us to explain the nonexponential behavior of the capacitance versus capture time when the trap concentration is not negligible with respect to that of the shallow one, and the Debye tail effects are taken into account. A figure of merit for the nonexponential behavior of the capture process is shown and discussed for different situations of doping and applied bias. We have also considered the influence of the position of the trap level"s energy on the nonexponentiality of the capture transient. The experimental results are given for the gold acceptor level in silicon and for the DX center in Al0.55 Ga0.45As, which are in good agreement with the developed theory.
