    Discourse Markers and Modal Expressions in Speakers with and without Asperger Syndrome: A Pragmatic-Perceptive Approach

    From a theoretical point of view, this paper offers a new framework for the analysis of discourse markers: a pragmatic-perceptive model that emphasizes the point of the communication process in which such particles become more relevant. Furthermore, this approach tries to give an account of the modal expressions (attenuators and intensifiers) that speakers use in oral speech. The quotients of absolute and relative frequency with regard to the use of textual, interactive and enunciative markers - focused on the message, the addressee and the addresser respectively - are compared in two samples of 20 subjects with typical development and other 20 with Asperger syndrome. The general results of this research suggest that these latter speakers display a suitable command of textual markers, whereas they overexploit the enunciative ones in conversation

    Consumer populations and nutritional transition in Spain in the 20th century: A methodology for their reconstruction

    Get PDF
    One feature of the modern nutrition transition is the growing consumption of animal proteins. The most common approach in the quantitative analysis of this change used to be the study of averages of food consumption. But this kind of analysis seems to be incomplete without the knowledge of the number of consumers. Data about consumers are not usually published in historical statistics. This article introduces a methodological approach for reconstructing consumer populations. This methodology is based on some assumptions about the diffusion process of foodstuffs and the modeling of consumption patterns with a log-normal distribution. This estimating process is illustrated with the specific case of milk consumption in Spain between 1925 and 1981. These results fit quite well with other data and indirect sources available showing that this dietary change was a slow and late process. The reconstruction of consumer population could shed a new light in the study of nutritional transitions.

    Health intervention and decline in infant mortality rates. Milk depots in Spain (1900-1936)

    Get PDF
    The role of public health has been a central topic on the classical debate about the historical mortality decline in Europe. One of these health initiatives were the Milk Depots. Spain set up those centres from the late 19th century until the beginning of the Civil War. The goal of this paper is to evaluate the effect of this health intervention on the infant mortality decline during this period. This study works out three kinds of sources: Statistical Yearbooks, Official documents and local records produced by the same Milk Depot. It analyses data available for all the country and one local case such as the Barcelona’s Milk Depot (1904-1935). The main methodological issue deals with the measurement of the effect of the Milk Depot activities on the pattern of changes of infant mortality. Results suggest that Milk Depots have a positive but quite moderate effect on the improving of overall levels of child survival.

    Generic behavior of asymptotically holomorphic Lefschetz pencils

    Full text link
    We study some asymptotic properties of the sequences of symplectic Lefschetz pencils constructed by Donaldson. In particular we prove that the vanishing spheres of these pencils are, for large degree, conjugated under the action of the symplectomorphism group of the fiber. This implies the non-existence of homologically trivial vanishing spheres in these pencils. Moreover we show some basic topological properties of the space of asymptotically holomorphic transverse sections. These properties allow us to define a new set of symplectic invariants of the original symplectic structure

    Lagrangian submanifolds and Lefschetz pencils

    Get PDF
    Given a Lagrangian submanifold in a symplectic manifold and a Morse function on the submanifold, we show that there is an isotopic Morse function and a symplectic Lefschetz pencil on the manifold extending the Morse function to the whole manifold. From this construction we define a sequence of symplectic invariants classifying the isotopy classes of Lagrangian spheres in a symplectic 4-manifold.Comment: 40 pages, 1 figur

    Does it pay to be socially responsible? Evidence from Spanish retail banking sector

    Get PDF
    This paper presents a theoretical and empirical analysis of strategic competition in retail banking when some of the financial firms are non-profit organisations that invest in social activities. Banking literature about competition is fairly large, but the strategic interaction between profit maximizing and non profit maximizers has not been extensively analysed except for Purroy and Salas (1999). In this paper, a completely different approach is taken. An adaptation of Hotelling’s two stage model of spatial competition is developed to take into account consumer perceptions respect to the two different types of financial institutions. The empirical analysis confirms that consumers take into account other features different from the price, such as social contribution or closer service to make a deposit or mortgage decision. These conclusions are of interest in the debate about a firm’s social or ethical activities. It is shown that if consumers value social activities, firms can improve their results by behaving socially responsible.Strategic competition; Hotelling´s model; Spanish banking; Corporate social responsibility

    Teaching skills in virtual and blended learning environments

    Universities are currently immersed in what is known as the process of European convergence to create the European Higher Education Area (EHEA). The aim is to establish a standardized, compatible and flexible European university system that enables graduates and undergraduates to move easily from one institution to another within Europe. As a result of evaluation mechanisms, the system will be transparent and of high quality, which will make it attractive and competitive internationally in a globalized world. In this paper, we focus on two distance learning modes that will become more important as a result of this change in universities: e-learning and b-learning. These basically involve the virtualization of learning processes through the use of computer equipment. We carried out a qualitative study using the case study method. The results indicate that teaching staff use information and communication technology (ICT) to improve student learning. Similarly, a high percentage (78%) of lecturers use some form of digital platform as a support for teaching. In conclusion, training policies should strengthen university teachers’ skills in the use of ICT equipment, tools and resources related to blended and virtual learning
