Genome sequence of Plesiomonas shigelloides strain 302-73 (serotype O1)

Plesiomonas shigelloides, the only species of the genus, is an emergent pathogenic bacterium associated with human diarrheal and extraintestinal disease. We present the whole-genome sequence analysis of the representative strain for the O1 serotype (strain 302-73), providing a tool for studying bacterial outbreaks, virulence factors, and accurate diagnostic methods.

How The 1996 Hotel Majestic agreement may explain a future PP/CiU relationship in Madrid

Some historians have argued that 1996 marked a ‘second transition’ for Spain because of the return to power of the political right in Madrid and that the relationship and eventual pact between the Partido Popular (PP) and Convergència i Unió (CiU) meant that the state could finally escape the ghosts of its Francoist past. For this research, face-to-face interviews were conducted with Catalan Members of Parliament who served under either José María Aznar or Jordi Pujol in Madrid or Barcelona. Drawing upon both interviews and other evidence, including the analysis of election results and the 1996 Hotel Majestic Agreement, the research seeks to provide a better understanding of the previous relationships between the PP and CiU and their leaders in order to understand what lessons might be learnt that would contribute to anticipating and explaining possible future negotiations between the two parties. This is attempted by first examining the potential costs and benefits of political pacts between centre (Madrid) and periphery (Barcelona). Secondly, due to many interviewees making reference to Salvador Espriu’s work La Pell de Brau, the three routes of Espriu’s Catalan nationalism are put into the context of the political pacts. Finally, the likelihood of future agreements between PP and CiU are hypothesized, not only how those agreements may (or may not) come about, but also, what might the result of those negotiations be. Ultimately, it is concluded that the benefits of the Hotel Majestic Agreement outweighed the costs, thus leaving the door open for future negotiations, even if some of those interviewed disagreed.

Deciding where to belong: gender differences in educational trajectories and migration in a rural Spanish town

From an anthropological perspective, formal post-secondary schooling is not an abstractentity with an intrinsic value that everyone finds desirable, but rather one alternative among many that young people evaluate from their different positions in the social field. The problem discussed in this paper is the diverging life trajectories that young men and women in a concrete rural context, at the end of the 20th century, shape for themselves at the ages of 14-16, a moment of decision created by national legislation regarding mandatory education (LGE, 1970, General Education Law, and LOGSE, 1990, General Organic Law of the Education System). Despite a strong cultural norm of equal inheritance divided among all children, male and female, and despite the equal educational opportunities provided by the Spanish State, different meanings of possession and use-rights over land and the resulting culturally accepted gendered division of work converge to orient men and women differently towards post-secondary schooling. Observation of the age, gender, and civil status structure of the population led to the preliminary query: Why do men and women, in this town, behave differently with respect to migration and marriage? The main hypothesis was that women’s longer school trajectories and resulting migration and men’s anchoring in the town and their higher rates of celibacy were not drastic changes in values, in the positional-relational sense of Bourdieu (1988, 2002), but the current outcome of previously existing dissimilar relations to property that produce dissimilar mobility. Through their schooling and work choices, young men and women, at very early ages, locate themselves in, or decide to belong to, different contexts that later reveal very different possibilities of finding marriage partners. This paper is based on an ethnographic study of a small rural town (302 inhabitants in 1950; 193 in 2000) near Leon. Although this paper deals with the situation in the final decades of the 20th century, we must also consider the first half of the century, where some elements that shape this situation have their roots. Fieldwork was carried out between 1988 and 2001, in periods of differing length and intensity. The social subjects discussed here are the domestic unit and its component members. They were studied in conjunction, analyzing the life-trajectory decisions of specific persons in the framework of the domestic unit and the relations among people and property which comprise it. The tried-and-true methods of ethnographic research –participant observation, interviews, and life-histories, etc.- were employed. Archival research was also important for producing demographic data. Demographic analysis, the analysis of the composition and transformation of domestic units, and the creation of life trajectories were among the principal techniques used. The theoretical analysis was oriented by Bourdieu’s (2002) framework of the social field, habitus, and difference.

An experimental study of adaptive behavior in an oligopolistic market game

We consider an oligopolistic market game, in which the players are competing firm in the same market of a homogeneous consumption good. The consumer side is represented by a fixed demand function. The firms decide how much to produce of a perishable consumption good, and they decide upon a number of information signals to be sent into the population in order to attract customers. Due to the minimal information provided, the players do not have a well--specified model of their environment. Our main objective is to characterize the adaptive behavior of the players in such a situation.

Anàlisi de la T2 en el Triatló

La manera en que el triatleta és capaç d’adaptar-se a la cursa a peu després de la segona transició, és decisiva en el resultat final en una prova de triatló. En aquest estudi s’avalua l’efecte del ciclisme sobre la longitud i freqüència de gambada durant la simulació de una transició ciclisme-carrera de traiatló en esportistes sub 23 i juniros élite. Cinc subjectes van realitzar dues proves: 1) Carrera de control (C), que consisteix en 3000 metres de carrera a màxima velocitat en una pista de 400 m (7’5 voltes). 2) Transició (T), consisteix en 30’ de ciclisme, 10’ d’escalfament i 20’ a zona de llindar anaeròbic, seguits de 3000 m de carrera a màxima velocitat possible. Es van mostrar diferencies importants amb la longitud de gambada: 339,61 cm a la prova C i 302,74 cm en la prova T, sobre tot als primers 600 metres, i en cap moment es va arribar a la longitud de la cursa C. Per tant concloem, que en la T2 hi ha un efectes negatius sobre la longitud de gambada durant els 3000 m, però sobretot, als primer 600 metres.

Lucía Moholy: la fotógrafa de la Bauhaus

Si bien Lucía Moholy realiza sus trabajos fotográficos más interesantes durante los años que permanece en la Bauhaus (1923-28) existe evidentemente un antes y un después de la Bauhaus en la vida de Lucía Moholy. El próposito de este articulo no se limita, pues, únicamente a valorar su colaboración en la Bauhaus, sino a enmarcar ésta dentro de toda una trayectoría profesional.

La génesis de la división territorial contemporánea en la España atlántica (Galicia, Asturias, Cantabria y El Bierzo)

Se estudian los antecedentes y gestación de la actual división provincial en la España atlántica, durante la transición del antiguo régimen al liberalismo (1800-1850). Las provincias se entienden como resultado de la convergencia de la voluntad racionalista y uniformadora del Estado con los intereses de auto-organización regional de la periferia.

The Plesiomonas shigelloides wbO1 gene cluster and the role of O1-antigen LPS in pathogenicity

The Plesiomonas shigelloides 302-73 strain (serotype O1) wb gene cluster encodes 15 proteins which are consistent with the chemical structure of the O1-antigen lypopolysaccharide (LPS) previously described for this strain. The P. shigelloides O1-antigen LPS export uses the Wzy-dependent pathway as correspond to heteropolysaccharides structures. By the isolation of two mutants lacking this O1-antigen LPS, we could establish that the presence of the O1-antigen LPS is crucial for to survive in serum mainly to become resistant to complement. Also, it is an important factor in the bacterial adhesion and invasion to some eukaryotic cells, and in the ability to form biofilms. This is the first report on the genetics from a P. shigelloides O-antigen LPS cluster (wb) not shared by Shigella like P. shigelloides O17, the only one reported until now.

Un estudi de cas: inclusió d'un infant amb paràlisi cerebral

En aquesta investigació qualitativa s’ha fet un estudi sobre la possibilitat d’incloure a un infant amb paràlisi cerebral en una escola ordinària. Per fer-ho, s’ha treballat a partir de l’estudi de cas d’un infant concret escolaritzat en un centre d’educació espacial. S’ha realitzat un anàlisi de la realitat d’aquest centre, l’Arboç, i de dos centres on les investigadores han realitzat l’estada de pràctiques, a l’escola Camí del Mig i a la Llàntia. Els instruments utilitzats al llarg del procés de recerca han estat les entrevistes, les graelles d’observació, el diari de camp i l’anàlisi de documents dels centres. Aquests s’han complementat amb una observació directa i participant a les escoles esmentades. La conclusió obtinguda després d’haver realitzat tot el procés d’investigació, és que la inclusió d’aquest infant no seria possible en els dos centres ordinaris estudiats, ja que seria necessari introduir un seguit de canvis a nivell d’infraestructures, metodologia, organització i de recursos humans i materials.

Reparar y sustituir cosas en la compraventa : evolución y últimas tendencias

International texts recognise the buyer's right to the repair or replacement if the goods do not conform with the contract, and at the same time, establish exceptions to their application and certain rules of protection for the seller (Art. 46 CISG, Art. 7.2.3 UNIDROIT Principles of International Commercial Contracts, Art.9:102 PECL and Arts. 4:202 y 4:204 (1) PEL S). This approach is a result of a compromise between civil law systems and the common law and it has been widely extended to the regulation of consumer sales over the last decade (Art. 3.3 of the Directive 1999/44/CE, Art. III.-3:302 DCFR, Art. 26 of the proposal for a Directive on Consumer Rights). These norms regulate the different ways of requiring the fulfilment of a contractual obligation from a new paradigm which has little to do with a need to protect the weak consumer which governed the origins of consumer policy in the European Community. Now the idea of the consumer who shall behave economically efficiently prevails in Art. 3.3 of the Directive 1999/44/CE, a norm which is clearly influenced by the international texts and whose transposing into the national legislation of Member States has created important problems for traditional dogmas. In this sense there are still some unclear issues, such as the possibility of replacing in sales of goods of specific nature or second-hand goods, some aspects on the exercise of repair and replacement, and, even, their use as primary remedies rather than a reduction in price or a rescission of the contract. With regard to this, in England the possibility of offering the consumer free choice between these measures if the goods do not conform with the contract has been raised. This is far from the principle of pacta sunt servanda and is clearly contrary to the economic approach of the proposal for a Directive on Consumer Rights. Up to now Spain has limited itself to implementing Art. 3.3 Directive 1999/44/CE into its legal system in almost literal terms and the case law on the issue has completely turned out to be insufficient. By contrast with Germany, the Spanish legislator has not extended the application of the rules of repair and replacement of Directive 1999/44/CE to nonconsumer sales, even though two draft bill proposals along these lines presented by the General Commission for Codifying (“Comisión General de Codificación”), the last one being in January, 2009
