OPTIMAL PRICING AND GRANT POLICIES FOR MUSEUMS

Considering two potential sources of income (public grants and ticket revenues),we have defined a theoretical model where the public agency is the principal and the manager of the museum is the agent. This model allows us to design the optimal contract between both sides and thus to establish the optimal values of grants, ticket prices, budget and effort applied by the manager. Furthermore, we have found a theoretical reason to explain the inelastic pricing strategy that has been found in some of the empirical research on cultural and sports economics. The main conclusion is that the optimal contract allows a Pareto optimum solution in prices that does not change if we introduce moral hazard into this relationship. This solution allows us to conclude that the public agency should regulate ticket prices in accordance with the social valuation. However, public grants and museum budgets would be affected by the existence of this problem, moving the equilibrium away from the Pareto optimum situation. In this case, even with a risk averse manager and a risk neutral public agency, grants and budgets will depend on results because higher budgets related to good results provide the main incentives to increase the manager’s level of effort. Although the focus of this paper is on museum administration, the model that we have developed can be easily generalized and applied to other institutions, such as schools, sport facilities or NGOs, which are able to raise funds directly from private (e. g. ticket revenues or membership fees) or public sources (e.g. public grants).cultural economics, grants, public prices, museums, principal- agent model

Dysfunctionalities. Annual Conference of the German Society for Media Science (GfM), Potsdam, Germany, 5-8 October 2011

During the 1970s the intense use of audiovisual media in Germany encouraged a vigorous debate among philologists. The outcome of this discussion was the establishment of Media Studies as an independent discipline in the German high education system in the second half of the 1980s (“Fachgeschichte”). The German Society for Media Studies was founded in November 1985 as a forum for academic exchange and dialogue, as well as an initiator of public debate around media-related issues. Aesthetic, historical, sociological, psychological and communicational perspectives were equally considered within the GfM, and this multilayered critique of media production and consumption continues today (“Der Gesellschaft”)

Arte popular. Arquitectura hidráulica del norte de Burgos, de la Ilustración a fines del siglo XIX

El tema referido es un claro ejemplo de naturaleza-arte, donde podemos apreciar cómo el hombre se ha beneficiado de su principal recurso natural, el agua, llegando a realizar grandes empresas (construcciones populares) que, con la perspectiva que el paso de tiempo ofrece alcanzan en nuestros días un destacable valor sentimental, en el más puro sentido romántico, como elementos conformadores del paisaje burgalés.Departamento de Historia del ArteGrado en Historia del Art

Photo-abilities (working title)

This photographic exhibition revolves around the idea of ability. Physical and cognitive processes are reviewed and explored in the context of creative work. The photographs depict prototypes currently being used by people with severe functional limitations in Brighton, UK. This visual approximation to the object of study constitutes the first step of a larger collaborative research project between Ivan Garbayo and Patricia Prieto-Blanco. Ivan Garbayo is an Occupational Therapist who has been working with in this field for over a decade. By applying the principles of accessible design to visual production tools, he aims to both facilitate access as well as to foster social, economic and sensory inclusion of people with severe functional limitations. By applying visual research methods to this investigation, Patricia Prieto-Blanco aims to both reach wider audiences as well as to facilitate an interdisciplinary discussion about ability and creative expression. Audio-visual resources are valuable tools of stimulation that can be productively used to foster interaction and communication when working with people with severe functional limitations. But, what happens when the receivers become the producers? The aim of the photographic series is to both raise awareness as well as to foster an exploration of socio-cultural inclusion and embodiment

El desarrollo histórico del conocimiento sobre las disoluciones y su relación con la Teoría Cinético-Molecular. Implicaciones didácticas

El conocimiento sobre la naturaleza de la materia y sus propiedades tiene un papel importante en la educación científica. Los currículos en nuestro país incorporan la enseñanza de la teoría cinético-molecular (TCM), asumiendo que aspectos básicos de esta teoría pueden ser comprendidos, asimilados y aplicados por el alumnado de la Educación Secundaria Obligatoria. Al mismo tiempo, se han ido acumulando evidencias que muestran que el aprendizaje de la naturaleza de la materia presenta grandes dificultades, y se reconoce que una proporción alta de estudiantes no consigue una comprensión adecuada de aspectos básicos de ella.En este artículo se intenta arrojar luz sobre esta cuestión recurriendo al análisis histórico. En primer lugar, se hace un recorrido a través de hitos importantes que han conducido a la construcción de la TCM. En segundo lugar, se analizan las teorías y modelos más utilizados a lo largo de la historia para explicar los fenómenos de disolución, relacionándolos con la TCM. Finalmente, se plantean algunas implicaciones didácticas.Knowledge about the nature of matter and its properties has got an important role in science education. The curricula in our country include the teaching of the kinetic-molecular theory (KMT), assuming that basic aspects of this theory can be understood, assimilated and used by pupils of compulsory secondary education. At the same time, evidences showing that the learning of the nature of matter presents great difficulties have been accumulated, and the fact that a high proportion of students do not get a proper understanding of basic aspects of nature of matter has been recognised. In this article, we attempt to shed light on this issue by resorting to historical analysis. First, a tour through important milestones that have led to the construction of the KMT is made. Second, theories and models used throughout history to explain the phenomena of dissolution are discussed in relation to the KMT. Finally, some educational implications are formulated

How do your rivals' releasing dates affect your box office?

In this paper, we study to what extent a movie's box office receipts are affected by the temporal distribution of rival films. We propose a theoretical model that analyses the effects of past, present and future releases on a film's results. Using this model we can analyse how rivals' release dates impact on others' box office revenues. This theoretical model also allows us to carry out some comparative statics by changing some relevant parameters such as time depreciation, film quality or the timeline of exhibition. We have tested the empirical implications of this model using information on the films released in five countries: the USA, the United Kingdom, Germany, France and Spain. In order to maintain a degree of homogeneity, we have constructed an unbalanced panel consisting of films that were released in at least three of these countries. The geographical dimension of our data set allows us to use panel data techniques to control for unobserved heterogeneity among the films released. This allows us to control for one of the most relevant features of the movie market, namely the presence of highly differentiated products.temporal competition, movie exhibition, film industry, panel data, unobserved heterogeneity, differentiated product

Theoretical Modelling of Ion Exchange Processes in Glass: Advances and Challenges

In the last few years, some advances have been made in the theoretical modelling of ion exchange processes in glass. On the one hand, the equations that describe the evolution of the cation concentration were rewritten in a more rigorous manner. This was made into two theoretical frameworks. In the first one, the self-diffusion coefficients were assumed to be constant, whereas, in the second one, a more realistic cation behaviour was considered by taking into account the so-called mixed ion effect. Along with these equations, the boundary conditions for the usual ion exchange processes from molten salts, silver and copper films and metallic cathodes were accordingly established. On the other hand, the modelling of some ion exchange processes that have attracted a great deal of attention in recent years, including glass poling, electro-diffusion of multivalent metals and the formation/dissolution of silver nanoparticles, has been addressed. In such processes, the usual approximations that are made in ion exchange modelling are not always valid. An overview of the progress made and the remaining challenges in the modelling of these unique processes is provided at the end of this reviewThis research was funded by Xunta de Galicia, Consellería de Educación, Universidades e FP, Grant GRC Number ED431C2018/11, and Ministerio de Economía, Industria y Competitividad, Gobierno de España, Grant Number AYA2016-78773-C2-2-P, European Regional Development FundS

Polymeric Particulates to Improve Oral Bioavailability of Peptide Drugs

Oral administration remains the most convenient way of delivering drugs. Recent advances in biotechnology have produced highly potent new molecules such as peptides, proteins and nucleic acids. Due to their sensitivity to chemical and enzymatic hydrolysis as well as a poor cellular uptake, their oral bioavailability remains very low. Despite sophisticated new delivery systems, the development of a satisfactory oral formulation remains a challenge. Among the possible strategies to improve the absorption of drugs, micro- and nanoparticles represent an exciting approach to enhance the uptake and transport of orally administered molecules. Increasing attention has been paid to their potential use as carriers for peptide drugs for oral administration. This article reviews the most common manufacturing methods for polymeric particles and the physiology of particle absorption from the gastrointestinal (GI) tract. In a second part, the use of polymeric particulate systems to improve the oral absorption of insulin is discussed
