The concept of international intelligence has taken on a greater importance for companies seeking to internationalize and access foreign markets. An exhaustive environmental scan—including international competitors, suppliers, clients in target countries, legislation and the political situation in other territories, and others—involves gathering the necessary information, its analysis and subsequent dissemination, and decision making. Within the context of the important role to be played by information management professionals who are specialized in foreign information, this article describes the information resources that Spanish companies have available to them that can assist them as they enter foreign markets.  相似文献

ABSTRACT

This article adopts a cultural historical approach to novels and plays about bandits in Spain, developing methods pioneered for other countries and periods, and examines the significance of stories about such famous criminals as Diego Corrientes and Jaime el Barbudo. Although nineteenth-century Spanish bandits superficially resemble Hobsbawm's social bandits, it is argued that these characters were reinvented as vehicles to explore the nature of legitimate government. The significance of these bandit stories as sources depends on an appreciation of their historical resonance and the danger and ambiguity of their association with real crime and the masses.  相似文献

The need for this study lies in the assumption that an in-depth examination of the map site of a firm that has a well-developed website can provide patterns about its corporate strategy through all the elements surrounding the organisation, and even a primary source for benchmarking. This technique has made it possible to identify the key issues in the strategic management of the most excellent large Spanish firms and also to describe trends in this sense. The methodology used consisted in a content analysis of the web pages of the Ibex35 companies of the Spanish Stock Market. Rather than focusing on the breakdown of businesses developed by each corporation, it was thought more appropriate to assess their respective corporate principles, as this would allow a better identification of the underlying managerial, organisational and strategic realities of these organisations. As a conclusion we can say that thanks to this technique, it has been possible to identify the key issues in the strategic management of the most excellent large Spanish firms. Additionally, it is shown how this way of working can be generalised to any group of enterprises.  相似文献

This study explored mainstream education teachers' perceptions of instructional adaptations in inclusive classrooms and its feasibility, effectiveness, and desirability of implementation. It was of particular interest to know how teachers of different grade levels would respond to such adaptations. Kindergarten (n = 16), elementary (n = 34), secondary (n = 26) and high school (n = 13) teachers rated the feasibility, effectiveness and desirability of 29 items on the Teaching Adaptation Scale. Results indicated a moderate teacher acceptance of instructional adaptations. Additionally, statistically significant differences between grade grouping (high school vs compulsory grades) surfaced. Findings are discussed in the light of needs of professional practice and significant reforms to improve curriculum preparation programmes.  相似文献

The taifa of Denia on the Iberian eastern seaboard was one of the most dynamic of the regional polities that emerged from the disintegrated Cordovan caliphate. Mujāhid al-‘āmirī based his state not only on its continental territories, but especially on the maritime networks that linked it with the Mediterranean. Commerce with Muslim and Christian ports played a role in Denia's success, but both Latin and Arabic sources emphasise its practice of piracy on a grand scale. In fact, Mujāhid al-‘āmirī built his state as a continuation of the maritime policies of the Cordovan caliphate under which the piracy of independent coastal communities was adopted and expanded into a state-sponsored guerre de course. Mujāhid's pursuance of this policy stemmed from his role in the erstwhile caliphate, but was also motivated by a combination of religious, political and economic factors. The legitimacy provided by his “jihād on the sea” helped to shore up his power at a time of political instability. This policy also provided the taifa's economic foundation for much of its history. In fact, the Mediterranean maritime lanes became as much an extension of Denia as its continental territories. Denia's piracy thus reflects a coherent form of statecraft, informing definitions of the medieval state and territoriality.  相似文献

This paper proposes a frequency-based approach for the detection of replay attacks affecting cyber-physical systems (CPS). In particular, the method employs a sinusoidal signal with a time-varying frequency (authentication signal) into the closed-loop system and checks whether the time profile of the frequency components in the output signal are compatible with the authentication signal or not. In order to carry out this target, the couplings between inputs and outputs are eliminated using a dynamic decoupling technique based on vector fitting. In this way, a signature introduced on a specific input channel will affect only the output that is selected to be associated with that input, which is a property that can be exploited to determine which channels are being affected. A bank of band-pass filters is used to generate signals whose energies can be compared to reconstruct an estimation of the time-varying frequency profile. By matching the known frequency profile with its estimation, the detector can provide the information about whether a replay attack is being carried out or not. The design of the signal generator and the detector are thoroughly discussed, and an example based on a quadruple-tank process is used to show the application and effectiveness of the proposed method.  相似文献

The idiosyncrasy of national academic discourses in educational sciences and the flow of ideas between them is a topic that has inspired recent research, even though it has not been treated very exhaustively. This study presents some results of an investigation into German influences on the Spanish academic discourse in educational sciences between 1945 and 1990. Considering system theory as a tool, which makes it possible to widen the knowledge of educational science about itself, the research is based on the idea that all communications between scientists, who represent a certain discipline, constitute the core of a scientific discourse. In this perspective, scientific disciplines appear as social‐communicative networks of knowledge production, which regulate themselves. The basic element of communication, which produces and reproduces the self‐regulated context of the scientific discipline, is the publication. To that extent this study assumes that scientific reviews reflect truly the condition of a discipline and uses their analysis as a method to survey the possible influence of a national academic discourse on another, i.e. how certain ideas cross the boundaries of their own reference system. These assumptions constitute the background for the quantitative and qualitative analysis of two important Spanish reviews, the Revista Española de Pedagogía and the Revista de Educación. The register of all authors and titles of any article that contains the quotation of a German author, all quoted German authors and the titles of their works, all authors and titles related to German educational sciences and all reviews of books edited by German authors allows quantitative statements concerning the presence of German influences on Spanish academic discourse. Furthermore, the interpretation of some selected articles published by Spanish authors illustrates the quality of this reception. The analysis of these data shows as the most important result that the quantity and frequency of quotations of German authors in both Spanish reviews are positively related to the presence of a relatively small group of Spanish educationists among the authors of their articles. A prosopographic approach to these authors discovers that they share certain characteristics, such as for example high interest in German academic discourse, often due to longer stays at German universities. The interpretation of some selected articles identifies different types of reception of the German discourse. Besides a small number of articles that reflect the quoted ideas correctly in their context, there are a large number of studies that use the quotations of German literature only in order to strengthen their own point of view without regarding the original context of their sources. These cases shed light upon the structural differences between the German and Spanish academic discourse in educational sciences and illustrate the difficulties for the exchange of educational ideas between different national debates.  相似文献

This paper describes the journey through France, Switzerland, Austria-Hungary, Germany and Belgium that was undertaken in August and September 1882 by Manuel Bartolomé Cossío, the foremost Spanish educationist of the late nineteenth and early twentieth centuries, in order to examine European education museums and schools with a view to preparing himself for the directorship of the Museo Pedagógico Nacional of Madrid, which he would occupy in December 1883. Cossío described this experience in a diary and a notebook in which he recorded his opinion of the institutions and educationists he visited in Paris, Berne, Zurich, Munich, Vienna, Prague, Dresden, Berlin, Leipzig, Cologne and Brussels; the former included the Ecole Alsacienne in Paris and the Pädagogium in Vienna, and the latter Friedrich Dittes, Henriette Breymann and Alexis Sluys. Not only do Cossío’s notes illustrate his personality and provide a subjective snapshot of the state of European education museums in the early 1880s; this tour is a paradigm of one way in which educational ideas and practices were propagated throughout nineteenth-century Europe by discriminating observers whose accounts served to open new horizons and legitimise educational innovation. Cossío found no ideal model for the Madrid museum, but what he saw moulded a project of transnational inspiration by combining autochthonous Spanish initiatives with the most fruitful trends developed in other European cultures that was to exert a profound influence on Spanish education.  相似文献

This article shows how the dialogic approach adopted by some schools in Spain generates a shift in approaches to gender violence, an issue still not explored in the literature. The shift is from an approach determined mainly by female experts to a dialogic one in which all women, including teachers, mothers, students, sisters, stepsisters, friends, and volunteers, are involved in designing and implementing programmes to prevent gender violence. An analysis of data obtained from six primary schools in Spain shows how the voices of all women are relevant to identify situations of gender violence that girl pupils are experiencing, as well as in the design of school‐based processes to prevent violence that affects these girls.  相似文献
