Seismic imaging techniques can be subdivided into inversion and migration. The object functions for inversion and migration are, respectively, the medium contrast parameters and reflectivity. In this paper, the relationship between inversion and migration is approached by analyzing the underlying representations (the forward models). It appears that the “two‐way representation” (which underlies inversion) as well as the “one‐way representation” (which underlies migration) can both be expressed in terms of a volume integral over the appropriate object function. In their linearized form, these representations account for primaries only. In this case, the one‐way representation in terms of reflectivity is the most accurate of the two, which implies that proper migration is more accurate than linearized inversion. Internal multiples can be taken into account by the nonlinear representations. As an alternative, however, the “generalized primary representation” is introduced. In its explicit form, this one‐way representation is linear in the reflectivity (opposed to linearized). Nonlinear effects are implicitly accounted for by the generalized primary propagators. The generalized primary representation is a suitable basis for true amplitude migration, taking the angle‐dependent dispersive effects of fine layering into account.

This article looks at the relationship between Haitian vodou, sound recording, and migration. I argue that Haitian vodou has a special relationship with technologies of sound, understood in Jonathan Sterne's sense of media as embodiments of social desire. There is a parallel between vodou possession and the practice of pwen (throwing verbal insults), on the one hand, and, on the other, the tape recorder's ability to manifest a person through the sound of his or her voice, making him or her present both in Haiti for the Haitian vodou congregation and in the diasporic land, thus bridging the separation across oceans and time. This transnational character underscores how Haitian vodou, which has been much maligned and often misunderstood, is an incredibly flexible and adaptive religion, necessary as a means of cultural survival for citizens of one of most economically disadvantaged nations, harshly subject to insertion in global neo-liberal labour markets.

Since the last century, we have witnessed a steady evolution of advertising techniques in an effort to adapt to the new social context in the market. As a strategic resource, Neuroscience brings a new perspective by allowing you to explore those difficult or verbally unconscious motives behind consumer behaviours. The present work aims to discover the relationship between the emotions induced in audiovisual advertising messages and their impact on the memory of the subjects. To achieve this goal, an experiment was carried out with eight audiovisual advertising messages (six representatives of the basic emotions: joy, surprise, anger, disgust, fear and sadness, and two rational ones that show the technical specifications of the product). Neuromarketing techniques such as the electrical activity of the heart (ECG) and the electrodermal activity (EDA) of the subjects are used, on one hand; and, on the other, a conventional research technique, a questionnaire applied to the subjects that participated in the research. The results show variations in the measures performed in the commercials corresponding to joy, surprise and anger, while for both, remembrance of the message transmitted and activity of the advertiser, the commercial with the best results has been the one regarding sadness, advertisement that has also been considered the most attractive for participating subjects. Desde el siglo pasado hemos presenciado una evolución constante de las técnicas de comunicación publicitarias en un intento de adaptación a las nuevas realidades sociales del mercado. Como recurso estratégico, la Neurociencia aporta una nueva perspectiva al permitir explorar aquellos motivos difíciles de verbalizar o inconscientes que hay detrás de los comportamientos de los consumidores. El presente trabajo tiene como objetivo descubrir la relación entre las emociones inducidas en los mensajes publicitarios audiovisuales y su impacto en el recuerdo de los sujetos. Para alcanzar este objetivo se ha realizado un experimento con ocho mensajes publicitarios audiovisuales (seis representativos de seis emociones básicas: alegría, sorpresa, ira, asco, miedo y tristeza; y dos racionales) en el que se han utilizado, por un lado, técnicas de Neuromarketing como son la actividad eléctrica cardíaca (ECG) y la actividad eléctrica de la dermis (AED) de los sujetos; y, por otro, una técnica de investigación convencional, un cuestionario aplicado a los sujetos que han participado en la investigación. Los resultados ponen de manifiesto variaciones en las medidas realizadas en los mensajes correspondientes a la alegría, la sorpresa y la ira, mientras que, tanto para el recuerdo sugerido del mensaje trasmitido como para la actividad del anunciante, el anuncio con mejores resultados ha sido el de la tristeza, anuncio que también ha sido considerado el más atractivo para los sujetos participantes.

Abstract In a time when the two major strategies followed by Christian religious traditions in modernity have lost traction—Christendom and subcultural isolation on the one hand and liberal and socialist assimilation with modernity on the other hand—Charles Taylor’s Catholic modernity idea opens up a “third grand strategy,” a new perspective on the relationship between religion and modernity. Moreover, the perspective can be put to use in other religious traditions as well. We will, hence, argue for the extension from a Catholic modernity to a religious modernities perspective. With the help of the arguments and suggestions as well as the critiques put forward by Taylor and the other authors in this volume Modernity and Transcendence, we will chart some of the main axes of this vast research field: (1) the clarification of Catholic/religious modernity; (2) the generalization of the Catholic modernity idea into a religious modernities perspective; (3) the invention of an inspiring, post-Christendom Christianity/post-fusional religion and theology; (4) the issue of religious engagement in our time—what Taylor calls “the Ricci project”; (5 and 6) the need for encompassing theories of modernity and religion (transcendence).

AbstractThis paper aims to provide a new perspective on the relationship between Nationalist Party (GMD) cadres and Chinese intellectuals. By studying the Central Politics School, a major GMD political training institute for professional party cadres, I hope to reassess the nature of the GMD one-party state and remind researchers of the difficult choices it faced between backing party-liners needed for the political struggle and accommodating depoliticized intellectuals needed for public administration. This paper will argue that GMD political impotence in competition with the Chinese Communist Party (CCP) was due less to an inadequate recruitment of capable experts than to the over-specialization of its well-trained cadres on technical tasks. In fact, the cadres from the Central Politics School generally resembled those considered to be ‘intellectuals’ at educational level and in ideology. This compels us to reconsider how to define ‘intellectuals’ and whether they were as uniformly alienated from the one-party state as most of the scholarly literature suggests.

The paper presents the theory of legal system polycentricism from a new perspective, i.e. the one integrating essentially contradictory concepts which explain this phenomenon in the context of the Polish jurisprudence. Apart from attempting to establish “common features” of these well-known concepts explaining the essence of polycentricism in the legal field, the presented point of view pertains to defining the relationship between the phenomenon of polycentricism from the legal discourse theory perspective and the Luhmann’s systems theory. The paper aims to prove the thesis that at present the legal system is internally taking on (transforming into) the heterogeneous type of internal structure due to interaction with already polycentric non-juristic domain, i.e. the social one.

The article analyzes A. Platonov's novel Bread and Reading, which is the first part of an unfinished trilogy called Technical Novel. Different approaches to the analysis of the writer's anti-utopian strategy are considered, and certain terms related to the intra-genre typology of his works, which are still the subject of controversy in Platonov studies, i.e., utopia, anti-utopia, metautopia, dystopia, and cacotopia are clarified. The article offers a new perspective on this problem and concludes that the short novel is characterized by a complex conflict between utopia and anti-utopia, namely, utopian consciousness is embodied in the form of anti-utopia, which leads to the ambivalence in meaning and the appearance of internal antinomies. This mainly revealed in the title of the story, the epigraph, a special type of plot situation and the character system structure. Platonov's work is characterized not only by the problem of the relationship between man and nature, but also that of between man and technology, which becomes a part of the anthropological worldview and acquires human features. Platonov's characters dream of a time when technology, nature and man are in a harmonious relationship, helping each other overcome universal entropy. The motif of construction sacrifice, traditional in the poetics of Platonov's works, plays an important role in the story: it is premature and shameful to think about personal happiness in the world of socialism that has not yet been built, without enough “bread and reading.” The work reflects Platonov's own hopes and doubts, and if the “principle of hope” (E. Bloch) is the main principle of utopian consciousness, then the writer's doubt becomes the main feature of his anti-utopia strategy. On the one hand, this makes it difficult to identify the genre of the short novel Bread and Reading (utopia or anti-utopia), on the other, it does not lead to an “imbalance” of forces, but, rather, to a meek awareness of the place of man in the world and his limited capabilities. An important role is also played by the fact that The Juvenile Sea was supposed to become the second part of the trilogy, and Dzhan may have made up the third part: the three works not only complement, but also “explain” each other. In the finale of Bread and Reading, the characters remain focused on the “distant,” as they stay in the same utopian dream space. Likely never having found a way out of the “impasse of utopia,” Platonov leaves Technical Novel unfinished.

This paper analyzes a dual relationship between Adorno and Durkheim: on the one hand, Adorno adopts Durkheim’s perspective on society, describing it as an obscure, opaque thing that individuals cannot understand by themselves; on the other, he tries to get out of the opacity that he recognizes as a structural moment of the society he lives in. This last point engages us in a discussion of the relationship between political sociology and philosophy of emancipation, which allows to study in a new perspective the only text Adorno published in his lifetime on Durkheim: his preface to Philosophy and Sociology, the critical violence of which is well known and often interpreted as a complete rejection of Durkheim’s sociology. The thesis of this article is that the conflict between Adorno and Durkheim is a political one and that the division between the two authors lies in their evaluation of the capacity of the modern capitalist society to produce out of itself common ideals that assure the justice of the actual social order.

My title is of course a variation on Professor H. D. Lewis' well-known Our Experience of God. There he expounded a variety of religious intuitionism, which stands in the line of Schleiermacher, Rudolf Otto and Martin Buber. These and other writers have characteristically made ‘the move to experience’, as a new blend of natural and revealed theology. The move makes a great deal of sense. On the one hand it grounds belief at a time when the older natural theology apparently had crumbled. On the other hand, it points to the dynamics of religious inspiration and gave a new perspective on revelation. It softens both reason and faith, of course, but it also provides a defence against skepticism. It fits well with a liberal attitude to scriptures and tradition. So there are manifest advantages of the move to experience, for those who wish to make it in the context of the Western theistic tradition. The writers I cited above, and Professor Lewis himself, have discussed religious experience from a mainly Western and theistic angle – even Otto with his great comparative concerns did so; and more needs to be said about the nature of religious experience in the broader context of Eastern and other religions. Lewis, however, paid attention to this wider problem, for instance in his 1963 article ‘Buddha and God’. In some respects this issue of the relationship of apparently non-theistic religions to theism is the most important one in contemporary crosscultural philosophy of religion.

Abstract. Based on responses from 158 reward managers located at the headquarters or subsidiaries of multinational enterprises, the present study examines the relationship between the centralization of reward management decision making and its perceived effectiveness in multinational enterprises. Our results show that headquarters managers perceive a centralized approach as being more effective, while for subsidiary managers this relationship is moderated by the manager’s role identity. Referring to social identity theory, the present study enriches the standardization versus localization debate through a new perspective focusing on psychological processes, thereby indicating the importance of in-group favoritism in headquarters and the influence of subsidiary managers’ role identities on reward management decision making.

Rural economies in developing countries are often characterized by credit constraints. Although few attempts have been made to understand the trends and patterns of male out-migration from Uttar Pradesh (UP), there is dearth of literature on the linkage between credit accessibility and male migration in rural Uttar Pradesh. The present study tries to fill this gap. The objective of this study is to assess the role of credit accessibility in determining rural male migration. A primary survey of 370 households was conducted in six villages of Jaunpur district in Uttar Pradesh. Simple statistical tools and a binary logistic regression model were used for analyzing the data. The result of the empirical analysis shows that various sources of credit and accessibility to them play a very important role in male migration in rural Uttar Pradesh. The study also found that the relationship between credit constraints and migration varies across various social groups in UP.
