An Investigation into Irish State patronage of the visual arts.

The focus of this research is in ascertaining how and why the Irish state patronises the visual arts. The framework that the state puts in place for the support of the arts influences the creation of art. The initial standpoint from which to evaluate the system is founded on the belief that art is of social good. The second source of belief is in the necessity for an autonomous setting in which it can be created. These two beliefs underpin state patronage of the arts in contemporary society. Therefore they have to be examined carefully in order to see if they hold up. This requires an investigation into the formation of value. This is undertaken by looking into the social development of western society and its influence on the placement of arts value. Establishing how arts value to society is defined provides a means by which to investigate the manner in which the state patronises the visual arts. Two case studies provide the evidence in how the state supports the arts and why it chooses to do so. The Irish Museum of Modem Art is used as an example of the state’s role in the maintenance of the canon of art. The second case study looks at the work being done by Breaking Ground. Breaking Ground is an extensive art project as an element of the regeneration process happening in Ballymun funded by the state. It provides and insight into how the state utilises art in the unification of a social group.

Estudos sôbre a excitação química da córtex cerebral (Ação da acetilcolina)

The author has studied the influence of acetylcholine solutions directly applied on the motor cortex of dogs, cats monkeys and rabbits. For this purpose small squares of filter paper were soaked in the acetylcholine solution and soon afterwards laid on the motor cortex. Solutions varying from 0,2 to 10 per cent have been experimented. It has been shown that local application of the solutions on the motor points, previously localized by induction coil, produced motor reactions. It has been found, in the dogs that 10 per cent acetylcholine solutions cause localized muscular twitchings (clonus) in almost all the animals experimented. Generalised epileptiform convulsions were obtained in44,4% of the dogs. Convulsions were also obtained by employing 1 per cent solution of acetylcholine. Definite response has been obtained with 0,2 per cent solution. Failure of motor action, pointed out by other authors, has been related to the use of anesthetics. Convulsions were easily produced by rapid light mechanical stimulations of the skin covering the muscles in conection with the excited motor point, and the application on the motor point of acetylcholine. The results on monkeys can be summarized as follows. Two species of monkeys were experimented: Cebus capucinus and Macaca mulata. In the monkeys C. capucinus generalised convulsive reactions were induced with actylcholine solutions in a concentration as low as 0,5 per cent. Motor reaction or convulsive seizeres were obtained in seven of the eight monkeys used. Three monkeys M. mulata were stimulated with 10 per cent acetylcholine solution but only localized muscular contraction hae been observed. Similar results has been obtained on the motor cortex of cats and rabbits. One of the three cats employed has shown epileptiform convulsions and the remaining only localized muscular contractions. In the rabbits muscular twitchings have been also induced. The sensitizing power of eserine on the action of acetylcholine has been also searched. The results indicate that a previous application of eserine solution on the motor center, potentiates the action of acetylcholine. The intensity of the muscular twitchings is greater than the obtained before the application of the eserine solution. Generalised epileptiform convulsions sometimes appeared following the use of lower concentrations of acetylcholine than those previously employed. Experiments have been carried out by injecting eserine and prostigmine by parenteral route. A dosis dufficient for induce small muscular tremors did not enhance obviously the motor effects produced by the application of the acetylcholine solutions on the motor cortex. From seven dogs experimented, all previously tested for convulsive seiruzes by application of 1 and 10 per cent acetylcholine solution with negative results, only one has shown epileptiform convulsions after the injection of prostigmine. Morphine has also been tested as facilitating substance for convulsions induced by acetylcholine. Six from the nine dogs submitted to the experiments, developed epileptiform seizures after injection of morphine and stimulation of the motor cortex with acetylcholine. (Table IV). In another series of experiments atropine and nicotine have been studied as for to their action on the motor effects of acetylcholine. Nicotine has a strong convulsant action, even when employed in very high concentration. Since a depressant effect has not appeared even by the applications of high concentrations of nicotine in the motor corteõ of dogs, unlike the classical observations for the autonomus nervous system, it was not possible to verify the action of acetylcholine on a motor center paralised by nicotine. It is important to not that the motor phenomena observed after the first aplication of acetylcholine, can desappear by the renewal of the pieces of filter paper soaked in the acetylcholine solution. Atropine, either applied on the motor point in low concentration, or injected in sufficient amount for inhibiting the “muscarinic effects” of acetylcholine on the autonomous nervous system, did not prevent the motor reactions of acetylcholine on the cerebral cortex.

On the identification of monetary (and other) shocks

The purpose of this paper is twofold. First, we construct a DSGE model which spells out explicitly the instrumentation of monetary policy. The interest rate is determined every period depending on the supply and demand for reserves which in turn are affected by fundamental shocks: unforeseeable changes in cash withdrawal, autonomous factors, technology and government spending. Unexpected changes in the monetary conditions of the economy are interpreted as monetary shocks. We show that these monetary shocks have the usual effects on economic activity without the need of imposing additional frictions as limited participation in asset markets or sticky prices. Second, we show that this view of monetary policy may have important consequences for empirical research. In the model, the contemporaneous correlations between interest rates, prices and output are due to the simultaneous effect of all fundamental shocks. We provide an example where these contemporaneous correlations may be misinterpreted as a Taylor rule. In addition, we use the sign of the impact responses of all shocks on output, prices and interest rates derived from the model to identify the sources of shocks in the data.

On the stability of periodic orbits in Rn

We consider an autonomous differential system in Rn with a periodic orbit and we give a new method for computing the characteristic multipliers associated to it. Our method works when the periodic orbit is given by the transversal intersection of n ¡ 1 codimension one hypersurfaces and is an alternative to the use of the first order variational equations. We apply it to study the stability of the periodic orbits in several examples, including a periodic solution found by Steklov studying the rigid body dynamics.

The Total fiscal cost of indirect taxation: an approximation using Catalonia's recent input-output table

In this note we quantify to what extent indirect taxation influences and distorts prices. To do so we use the networked accounting structure of the most recent input-output table of Catalonia, an autonomous region of Spain, to model price formation. The role of indirect taxation is considered both from a classical value perspective and a more neoclassical flavoured one. We show that they would yield equivalent results under some basic premises. The neoclassical perspective, however, offers a bit more flexibility to distinguish among different tax figures and hence provide a clearer disaggregate picture of how an indirect tax ends up affecting, and by how much, the cost structure.

Autonomy-enhancing paternalism

We present a form of soft paternalism called "autonomy-enhancing paternalism" that seeks to in-crease individual well-being by facilitating the individual ability to make critically reflected, autonomous decisions. The focus of autonomy-enhancing paternalism is on helping individuals to become better decision-makers, rather than on helping them by making better decisions for them. Autonomy-enhancing paternalism acknowledges that behavioral interventions can change the strength of decision-making anomalies over time, and favors those interventions that improve, rather than reduce, individuals ability to make good and unbiased decisions. By this it prevents manipulation of the individual by the soft paternalist, accounts for the heterogeneity of individuals, and counteracts slippery slope arguments by decreasing the probability of future paternalistic interventions. Moreover, autonomy-enhancing paternalism can be defended based on both liberal values and welfare considerations.

How collaboration could contribute to make Catalan journals visible on the Internet?

Cooperation between libraries is a universal language spoken in different dialects. In 1996 the libraries of the state-funded universities and the National Library of Catalonia (Spain) formed the Consortium of Academic Libraries of Catalonia (CBUC) to act as a channel for cooperation. The organization and activities of CBUC are an example of how this universal language has been adapted to the specific characteristics of the Libraries of Catalonia. Catalonia is an autonomous region of Spain with 7 million inhabitants with its own language, history and traditions and with a strong feeling of own identity that facilitates the cooperation. Thanks to this (and also to the hard work of the member libraries), since then, CBUC has created a union catalogue, an interlibrary lending program, the Digital Library of Catalonia, a cooperative store, different cooperatives repositories and other cooperation programs. One of these cooperatives repositories is RACO (Catalan Journals in Open Access, www.raco.cat) where can be consulted, in open access, the full-text articles of scientific, cultural and scholar Catalan journals. The main purpose of RACO is to increase the visibility and searches of the journals included and to spread the scientific and academic production published in Catalonia. This purpose makes specific in three aims: encourage the electronic edition of Catalan journals; be the interface that allows the whole search of all the journals and provide the instruments for its preservation. There are currently 244 journals in RACO, that includes more than 85.000 articles (80% in OA) from 50 publishing institutions. Since it got into operation it has had more than 4 millions of queries. These 244 journals offer the full-text of all the published issues. Nevertheless, some journal can have a delay between the introduction of the table of contents and the full-text for the recent issues. From 2005 we have a plan of retrospective digitization that has allowed to digitize more than 350.000 pages of back issues. The RACO repository works with the open source program OJS (Open Journal Systems, http://pkp.sfu.ca/ojs/) and uses Dublin Core Metadata and the interoperability protocol created by Open Archives Initiative (OAI) which allows to increase the visibility of the articles published in journals offering oneself together with other international repositories.

Applications of the MuSIASEM approach to study changes in the metabolic pattern of Catalonia

This document presents an integrated analysis of the performance of Catalonia based on an analysis of how the energy consumption (measured at the societal level for the Catalan Society) is used within both the productive sectors of the economy and the household, to generate added value, jobs, and to guarantee a given level of material standard of living to the population. The trends found in Catalonia are compared to the trends of other European Countries to contextualize the performance of Catalonia with respect to other societies that have followed different paths of economic development. The first part of the document consists of the Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM) approach that has been used to provide this integrated analysis of Catalan Society across different scales (starting from an analysis of the specific sectors of the Catalan economy as an Autonomous Community and scaling up to an intra-regional (European Union 14) comparison) and across different dimensions of analyses of energy consumption coupled with added value generation. Within the scope of this study, we observe the various trajectories of changes in the metabolic pattern for Catalonia and the EU14 countries in the Paid Work Sectors composed of namely, the Agricultural Sector, the Productive Sector and the Services and Government Sector also in comparison with the changes in the household sector. The flow intensities of the exosomatic energy and the added value generated for each specific sector are defined per hour of human activity, thus characterized as exosomatic energy (MJ/hour) (or Exosomatic Metabolic Rate) and added value (€/hour) (Economic Labour Productivity) across multiple levels. Within the second part of the document, the possible usage of the MuSIASEM approach to land use analyses (using a multi-level matrix of categories of land use) has been conducted.

Patients' prediction of extubation success.

The spontaneous breathing trial (SBT)-relying on objective criteria assessed by the clinician-is the major diagnostic tool to determine if patients can be successfully extubated. However, little is known regarding the patient's subjective perception of autonomous breathing. We performed a prospective observational study in 211 mechanically ventilated adult patients successfully completing a SBT. Patients were randomly assigned to be interviewed during this trial regarding their prediction of extubation success. We compared post-extubation outcomes in three patient groups: patients confident (confidents; n = 115) or not (non-confidents; n = 38) of their extubation success and patients not subjected to interview (control group; n = 58). Extubation success was more frequent in confidents than in non-confidents (90 vs. 45%; p < 0.001/positive likelihood ratio = 2.00) or in the control group (90 vs. 78%; p = 0.04). On the contrary, extubation failure was more common in non-confidents than in confidents (55 vs. 10%; p < 0.001/negative likelihood ratio = 0.19). Logistic regression analysis showed that extubation success was associated with patient's prediction [OR (95% CI): 9.2 (3.74-22.42) for confidents vs.non-confidents] as well as to age [0.72 (0.66-0.78) for age 75 vs. 65 and 1.31 (1.28-1.51) for age 55 vs. 65]. Our data suggest that at the end of a sustained SBT, extubation success might be correlated to the patients' subjective perception of autonomous breathing. The results of this study should be confirmed by a large multicenter trial.
