L'aportació dels romanistes alemanys als estudis de lingüística contrastiva del català amb altres llengües
2009
L’autor presenta i comenta les obres sobre gramàtica contrastiva del català i altres llengües realitzades per lingüistes alemanys des de 1502 fins a l’actualitat. S’hi consideren al voltant de quaranta títols referits de manera gairebé exclusiva als altres idiomes romànics i a l’alemany. Al començament, només era possible trobar qüestions de caire contrastiu en obres més generals, però a partir de 1917 comencen a aparèixer llibres i articles amb una orientació directament contrastiva.
Arte, Música y Conceptualismo en América Latina
2021
Se investiga la relación entre el arte y la música desde el conceptualismo, que valida la existencia de un arte sonoro y de una música conceptuales, cuyas estéticas se alejan de la percepción coclear, para enfocarse en el campo de las ideas. Se sientan los antecedentes y se analiza el desarrollo de estos campos en occidente (Europa y Estados Unidos de América) desde las vanguardias del siglo XX hasta los años 60, para luego hacer una cartografía de la historia del conceptualismo sónico en Latino América desde los años 50 al presente, al redefinir, revalorar y contrastar las aportaciones que se han hecho en el continente, con un enfoque que se centra más en lo político y social, pero sin olv…
Utilidad del color doppler, power doppler y el contraste sonográfico en el diagnóstico por imagen del cáncer de próstata localizado
2012
Objetivos: 1º. Estudiar el rendimiento diagnóstico de la ecografía transrectal en escala de grises, power doppler y del contraste sonográfico en el diagnóstico precoz por imagen del cáncer de próstata localizado. 2º. Comparar la rentabilidad diagnóstica de la biopsia prostática aleatoria con la biopsia ecodirigida mediante power doppler y contraste sonográfico, en el diagnóstico precoz por imagen del cáncer de próstata localizado. Material y métodos: Se diseñó un estudio epidemiológico prospectivo y transversal de ámbito provincial, para estudiar el rendimiento diagnóstico de la ecografía transrectal en escala de grises (EG), Power Doppler (PD) y del contraste sonográfico (CS) en el diagnós…
Road Functional Classification Using Pattern Recognition Techniques
2019
The existing international standards suggest a methodology to assign a specific functional class to a road, by the values of some features, both geometrical and use-related. Sometimes, these characteristics are in contrast with each other and direct the analyst towards conflicting classes for a road or, worse, one or more of these features vary heterogeneously along the road. In these conditions, the analyst assigns the class that, by his capability and experience, he retains the most appropriate, in a very subjective way. On the contrary, the definition of an automatic procedure assuring an objective identification of the most appropriate functional class for each road would be desirable. …
Organizational and Individual Values: Their Main and Combined Effects on Work Attitudes and Perceptions
1999
A survey was conducted using a convenient sample of employees (N = 999) from various industries to examine the main and combined effects of organizational and individual values on organizational commitment, perceived organizational support, and procedural justice. Moderated multiple regression analyses showed that employees' reactions were mainly explained by perceived organizational values and value preferences. In contrast, person-organization value fit and interaction effects were marginal. The implications of these findings are discussed.
Alternative Definitions of the Strategic Group and Explaining Value of Differences in Results
2010
The relationship between strategic groups and firm performance has been recurrently analysed for more than three decades. As can be confirmed by this work, the evidence found supports as well as refutes the significance of belonging to a specific strategic group in order to explain performance differences. Hence, in this work we have tried to review previous literature to provide a reasonable explanation to unevenness found in the empirical findings. This aim obliges us, firstly, to review previous literature taking into account alternative definitions of strategic group proposed by studies rooted in different theoretical traditions, strategic positioning approach, resource-based theory and…
Facilitadores en el procesamiento cognitivo de la información rítmica
2021
Rhythm perception models have studied an important variety of general characteristics of temporal structures and specific elements of musical rhythm, presenting a degree of heterogeneity in study objects. However, most of the research converges in the study of processes related to the listener's detection of an underlying temporal pulse. This, along with other processes such as temporal grouping, have been referred to as basic or primitive aspects, since they seem fundamental to the perception of simple rhythmic sequences. In the present work, a review of the literature in which research findings related to the cognitive processing of basic rhythmic aspects are described, synthesized and re…
Topological linguistics and the study of linguistic variation
1994
Publisher Summary This chapter focuses on topological linguistics and the study of linguistic variation. It discusses the problem of linguistic variation. A topological model has been developed for internal linguistics, starting from the epistemological problem that all linguists must deal with. A topological space could be conceived of as a set of elements where some elements limit the others and are said to be open-sets, and the former and the latter together constitute the closed-sets. Linguistics, when approaching its object of study, is faced with a very similar situation: a language is a set of elements—from utterances to minimal phonic items—where each is described by other surroundi…
The dynamic interactive pattern of assimilation and contrast: Accounting for standard extremity in comparative evaluations
2021
Abstract Social judgments are often influenced by comparison to some standard in the environment, either moving the judgment closer (assimilating) to or away (contrasting) from this standard. Which direction this effect will take depends heavily on the relative standing of these standards on the judgment dimension compared to the target of the judgment. In previous research, items and comparison standards were often selected arbitrarily, ignoring or simplifying their influence substantially. The current work takes a fine-grained holistic curve fitting approach to measure response patterns across a wide range of standard extremities, showing that a narrower approach can pose limits to the ge…
Color superposition: a new modality for contrast echocardiography.
1987
To improve the estimation of endocardial borders in echocardiography, a technique has been developed to combine images from contrasted and noncontrasted echocardiograms of the same heart-phase using a color superposition mode. This method allows both experienced as well as less experienced examiners to define the endocardial borders more reproducibly and objectively. This is achieved by displaying tissue structures as gray level images while the ventricular cavity is marked selectively by the color display of the contrast material zone. Results of volume estimations of the left ventricle by different examiners using several imaging modes including color superposition display are presented.
