The role of institutions in the contractual process

Human beings increase their productivity by specializingtheir resources and exchanging their products. Theorganization of exchange is costly, however, becausespecialized activities need coordination and incentiveshave to be aligned. This work first describes how theseexchanges are organized in an institutional environment.It then focuses on the dual effect of this environment-as with any other specialized resource, institutions maybe used for expropriation purposes. They enjoyspecialization advantages in safeguarding exchange butthey also make possible new forms of opportunism,causing new costs of exchange. Three perverse tendenciesare identified:In the legal field, there is a surplus ofmandatory rules and, at the same time, a deficit in default rules. Second, courts activity is biased againstthe quasi-judicial role of the parties and the market. Third, Market enforcement is based on reputationalassets that are badly exposed to opportunism.

Education export as a form of knowledge transfer : The potential of Finnish education export in Chile

Knowledge transfer is a complex process. Knowledge transfer in the form of exporting education products from one system of education to another is particularly complicated, because each system has been developed in a particular context to meet the requirements seen as relevant at each time. National innovation systems are often seen to form an essential framework within which the development of a country, its economy and level of knowledge are considered and promoted. These systems are orientated towards the future, and as such they also provide a framework for the knowledge transfer related to the development of education. In the best of circumstances they are able to facilitate and boost this transfer both from the viewpoint of the provider and the recipient. The leading thought and the idea of the study is that education export is a form of knowledge transfer, which is illustrated by the existing models included. The purpose of this study is to explore, analyze and describe the factors and phenomena related to education export, and more specifically, those related to the experiences and potential of Finnish education export to Chile. For better understanding, of the multiplicity of the issue involved, the current status of education export between Finland and Chile and he existing efforts within the Finnish innovation network will be outlined as well as new forms of co-operation between Finland and Chile in educational matters explored. Several countries have started to commercialize their education system in order to establish themselves as emerging education exporters. Moreover, the demand for education reform is accurate in many developing countries. This offers a good match between Finland and Chile to be the example countries of the research. The main research findings suggest that there are several business areas in education export. These include degrees in education, training services and education technologies for example The factors that influence education export can be divided into four groups, including academic, cultural, political and economic aspects. Challenges to overcome include the lack of product or services to be sold, lack of market and cultural knowledge of the buyer country, financing and lack of suitable pricing model. National innovation systems could be seen as enabling entities for successful education export. The extensive networks that national innovation systems aim to form, could operate as a basis for joining the forces in selling knowledge as well as receiving knowledge in a constructive way.

La dinámica del ordenamiento territorial en Colombia : contraste de dinámicas urbano-rurales en la región metropolitana de Bogotá

L’aménagement du territoire est le résultat de différents processus économiques, politiques, sociaux, culturels et environnementaux. Le territoire peut être vu de différentes manières et reflète les visions et les intérêts des acteurs qui le construisent. L'objectif principal de cette thèse consiste à explorer les dynamiques qui soutiennent l'aménagement de Bogota, capitale de la Colombie, et d’une municipalité avoisinant Soacha. L'analyse se concentre sur trois aspects qui correspondent aux objectifs spécifiques de cette étude : les récentes politiques publiques d'aménagement du territoire qui régissent la zone étudiée, le rôle des acteurs sociaux et les relations urbano-rurales créées dans ce nouveau contexte. La thèse souligne des éléments contextuels qui servent à comprendre les transformations récentes de Bogota et de Soacha dans leurs implications spatiales. Différents processus ont apparus dans la nouvelle géographie de cette région, y compris la mondialisation, les transformations économiques, les nouvelles lois relatives à l'aménagement du territoire, les nouvelles formes de participation, ainsi que les décisions des administrations municipales qui ont contribué à établir ce nouvel ordre. Les éléments théoriques traitées dans cette étude privilégient deux perspectives ou visions du territoire : 1) celle utilisée par l'État où le territoire est considéré comme un espace limité par des frontières; et 2) la perspective culturaliste où le territoire est défini par son appropriation et par par l’identité qu’il confère. Cependant, une nouvelle tendance émerge à travers l'intégration de ces deux perspectives, autant en Colombie que dans d’autres pays. Ainsi, l'analyse démontre que de nouveaux acteurs ont émergé, par exemple le Conseil territorial de la planification qui représente la concrétisation du discours de participation communautaire exprimé dans différentes lois. De plus, la population paysanne qui a résisté à l'expansion urbaine de Bogota constitue un acteur primordial. Les nouveaux patrons de relations urbaine-rurale démontrent une très grande diversité d'activités et de fonctions présentes dans cette nouvelle « frontière » très dynamique où des éléments urbains et ruraux sont combinés, toujours présents mais aussi toujours en évolution.

A study on the phylogeny and the ecology of ammonia-oxidizing bacteria using a new molecular marker based on the gene amoB

L'agricultura i la industrialització han causat un augment significatiu del nombre d'ambients rics en amoni. La presència de compostos nitrogenats redueix la qualitat de l'aigua, causant problemes de toxicitat, deteriorant el medi ambient i fins i tot afectant la salut humana. En conseqüència, la nitrificació s'ha convertit en un procés global que afecta al cicle del nitrogen a la biosfera. Els bacteris oxidadors d'amoni (AOB) són els responsables de l'oxidació de l'amoni a nitrit, i juguen un paper essencial en el cicle del nitrogen. Els primers oxidadors d'amoni foren aïllats a finals del segle XIX, però la lentitud del seu creixement i les dificultats per cultivar-los feren que fins als anys 80, amb els primers estudis emprant el gen 16SrDNA, no s'assolís un coneixement complert d'aquest grup bacterià. Actualment les bases de dades contenen multitud d'entrades amb seqüències corresponents a AOB. L'objectiu d'aquest treball era trobar, desenvolupar i avaluar eines útils i fiables per a l'estudi dels AOB en mostres ambientals. En aquest treball primer descrivim la utilització de la hibridació in situ amb fluorescència (FISH), mitjançant l'aplicació de sondes amb diana en el 16SrRNA dels AOB. La FISH ens va permetre detectar i recomptar aquest grup bacterià; no obstant, aquest mètode no permetia la detecció de noves seqüències, pel que es necessitava una nova eina. Amb aquesta intenció vam aplicar la seqüència de la sonda Nso1225 en una PCR. El fet d'amplificar específicament un fragment del 16SrDNA dels AOB va suposar el desenvolupament d'una nova eina molecular que permetia detectar la presència i diversitat d'aquests bacteris en ambients naturals. Malgrat tot, algunes seqüències pertanyents a bacteris no oxidadors d'amoni del subgrup β dels proteobacteris, eren també obtingudes amb aquesta tècnica. Així mateix, un dels inconvenients de l'ús del 16SrDNA com a marcador és la impossibilitat de detectar simultàniament els AOB que pertanyen als subgrups β i γ dels proteobacteris. El gen amoA, que codifica per la subunitat A de l'enzim amoni monooxigenasa (AMO), era aleshores àmpliament utilitzat com a marcador per a la detecció dels AOB. En aquest treball també descrivim la utilització d'aquest marcador en mostres procedents d'un reactor SBR. Aquest marcador ens va permetre identificar seqüències de AOB en la mostra, però la necessitat de detectar amoA mitjançant clonatge fa que l'ús d'aquest marcador requereixi massa temps per a la seva utilització com a eina en estudis d'ecologia microbiana amb moltes mostres. Per altra banda, alguns autors han assenyalat l'obtenció de seqüències de no AOB en utilitzar amoA en un protocol de PCR-DGGE. Amb la finalitat d'obtenir una eina ràpida i rigorosa per detectar i identificar els AOB, vam desenvolupar un joc nou d'oligonucleòtids amb diana en el gen amoB, que codifica per a la subunitat transmembrana de l'enzim AMO. Aquest gen ha demostrat ser un bon marcador molecular pels AOB, oferint, sense tenir en compte afiliacions filogenètiques, una elevada especificitat, sensibilitat i fiabilitat. En aquest treball també presentem una anàlisi de RT-PCR basada en la detecció del gen amoB per a la quantificació del gènere Nitrosococcus. El nou joc d'oligonucleòtids dissenyat permet una enumeració altament específica i sensible de tots els γ-Nitrosococcus coneguts. Finalment, vam realitzar un estudi poligènic, comparant i avaluant els marcadors amoA, amoB i 16SrDNA, i vàrem construir un arbre filogenètic combinat. Com a resultat concloem que amoB és un marcador adequat per a la detecció i identificació dels AOB en mostres ambientals, proporcionant alhora agrupacions consistents en fer inferències filogenètiques. Per altra banda, la seqüència sencera del gen 16S rDNA és indicada com a marcador en estudis amb finalitats taxonòmiques i filogenètiques en treballar amb cultius purs de AOB.

Governmentality, subject-building, and the discourses and practices of devolution in the UK

This paper uses a Foucauldian governmentality framework to analyse and interrogate the discourses and strategies adopted by the state and sections of the business community in their attempts to shape and influence emerging agendas of governance in post-devolution Scotland. Much of the work on governmentality has examined the ways in which governments have developed particular techniques, rationales and mechanisms to enable the functioning of governance programmes. This paper expands upon such analyses by also looking at the ways in which particular interests may use similar procedures, discourses and practices to promote their own agendas and develop new forms of resistance, contestation and challenge to emerging policy frameworks. Using the example of business interest mobilization in post-devolution Scotland, it is argued that governments may seek to mobilize defined forms of expertise and knowledge, linking them to wider political debates. This, however, creates new opportunities for interests to shape and contest the discourses and practices of government. The governmentalization of politics can, therefore, be seen as more of a dialectical process of definition and contestation than is often apparent in existing Foucault-inspired writing.

A new species of the Rhinella margaritifera group (Anura: Bufonidae) from Brazilian Pantanal

We describe adult morphology, advertisement call and some natural history traits of a new species of toad from the Pantanal, western Brazil. Rhinella paraguayensis sp. nov. belongs to the Rhinella margaritifera group, and is characterized by medium size, snout rounded in dorsal view, with a vertical apical ridge, supraorbital crests weakly developed, parietal crest not well developed, postorbital crest prominent, presence of a dorsolateral line of tubercles, tympanum evident, bony protrusions at angle of jaws, absence of vertebral apophyses and of projections on upper eyelids, and parotoid glands small. The new species is distinguished from other species of the group by geographic distribution and by the use of floating mats of vegetation as reproductive site.

Cytogenetics of a new species of Paratelmatobius cardosoi group (Anura : Leptodactylidae), with the description of an apparent case of pericentric inversion

The karyotype of a new species of Paratelmatobius from the P cardosoi group is described. As with other Paratelmatobius and Scythrophrys karyotypes, Paratelmatobius sp. (aff. cardosoi) shows a diploid number of 24 chromosomes, in addition to other similarities with the former karyotypes. The Paratelmatobius sp. (aff. cardosoi) karyotype differs from that of P. cardosoi in the morphology of pair 4, the NOR location and the C-bands in pairs 3 and 8 (exclusive to Paratelmatobius sp.) and those of pairs 7 and 9 (exclusive to P. cardosoi). Both karyotypes also differ in the amount of heterochromatin in pair 1. The presence of interstitial heterochromatin in the long arm of pair 1 and the interstitial C-bands in both arms of chromosome 5 are apparently synapomorphic characters of P. cardosoi and Paratelmatobius sp. (aff. cardosoi), since they are absent in the other Paratelmatobius and Scythrophrys karyotypes. In Paratelmatobius sp. (aff. cardosoi), the nucleolus organizer region is on the short arm of a small metacentric chromosome (pair 9), an arrangement similar to the NOR-bearing chromosome pair in the karyotype of P. poecilogaster and in karyotype 11 of Scythrophrys. A conspicuous heteromorphism unrelated to the sex determining mechanism was also observed and probably arose from a pericentric inversion.

Indicators of soil degradation in urban forests: Physical and chemical parameters

The fragmentation of forest habitats in urban areas has aroused increasing interest in recent years according to the growing environmental problems. The fragmentation of theses ecosystems is caused, in general, by the pressure of housing, agriculture and industry, causing losses in biodiversity and problems of soil degradation in the border areas of theses remnants. The establishment of indicators of soil degradation becomes essential for the implementation of conservation and reclamation. This study analyzes physical and chemical characteristics of soil under different forms of vegetation in the forest surrounding the Quilombo Forest, located in Campinas/SP - Brazil, and examines the possibility of using these indices as indicators of environmental degradation in urban remnants. The parameters analyzed were: specific weight natural (γn), specific weight of solids (γs) Ca, P, K, Mg, pH, organic matter, H + Al, Sum of Base (SB) Percent Base Saturation (V%), Cation Exchange Capacity (CEC). The study shows that in general the different forms of land used in the study area significantly changed (or according to) the physical aspects of soil The porosity and voids of the soil stood out as the best indicators of soil physical degradation in the layer 0-20 cm deep. In relation to chemical indices, the soil under the cultivation of cane sugar had a significantly higher pH, K, Ca, Mg and sum of bases. The areas of forest showed higher levels of phosphorus, organic matter and CEC, indicating the importance of maintaining vegetation and replacement for the cycling of organic matter.
