Este trabajo repasa los distintos métodos de cálculo que los astrónomos y matemáticos árabes medievales desarrollaron para ser aplicados a la práctica astrológica de la división de casas. Partiendo de una clasificación de estos métodos establecida por J.D. North (1986) y ampliada por E.S. Kennedy (1996), se recoge la información que se halla en estudios anteriores y se presentan nuevos datos como resultado del análisis de fuentes exploradas más recientemente, destacando ciertos elementos pertenecientes a una tradición astrológica occcidental.

In this paper two deductive systems associated with relevance logic are studied from an algebraic point of view. One is defined by the familiar, Hilbert-style, formalization of R; the other one is a weak version of it, called WR, which appears as the semantic entailment of the Meyer-Routley-Fine semantics, and which has already been suggested by Wójcicki for other reasons. This weaker consequence is first defined indirectly, using R, but we prove that the first one turns out to be an (...) axiomatic extension of WR. Moreover we provide WR with a natural Gentzen calculus. It is proved that both deductive systems have the same associated class of algebras but different classes of models on these algebras. The notion of model used here is an abstract logic, that is, a closure operator on an abstract algebra; the abstract logics obtained in the case of WR are also the models, in a natural sense, of the given Gentzen calculus.

Quins són els valors que regeixen la nostra vida? I per què vivim amb aquests valors i no amb uns altres? «Els valors van cap a on anem nosaltres perquè van amb nosaltres. ¬I mentre fem camí o mentre el busquem, els valors ens alimenten», diu el filòsof.

This essay begins with a look at the contribution made by Business Ethics and by Corporate Social Responsibility (CSR) to Business Education, and how the first two have moved to the last over time. Yet their contributions also reveal limitations that need to be taken into account in the debate on the training provided by Business Schools. This debate cannot be confined to speaking of disciplines and their cross-cutting natures but rather needs to focus directly on the kind of personal (...) profile fostered among business students. In the context of this debate on the future of Business Schools, the essay stresses the relevance of Peter-Hans Kolvenbach’s framework. He proposed an educational ideal based upon educating competent, conscious, compassionate, and committed people. This ideal took shape in the form of an educational paradigm integrating four dimensions: professional (_utilitas_), ethical-social (_iustitia_), humanist (_humanitas_) and spiritual (_fides_). The essay not only shows how each of these dimensions is in tune with some of the present proposals for renewing Business Education but also how Kolvenbach's more holistic approach can help to further integrate and spotlight the blind spots of each of them.

Presuppositions are well known phenomena. One way of treating them is as partial 'meaning-functions '. There is an attractive argument that holds that in order to explain the contrast between such sentences as "John came into the room" and "That bastard John came into the room" it is required to make our semantic theory essentially more complex. This argument appeals to the fact that contrasts such as the ones just mentioned play a role in the validity of logical inferences. In (...) this paper I argue that these contrasts can be accounted for by appealing to presuppositions. In order to defend this view we will have to offer a characterization of logical consequence that applies to sentences that involve presuppositions. (shrink)

Argues that Merleau-Ponty’s thought grounds itself on “non-coincidence” or, as he puts it, on “divergence or écart”, “non-transparence” or “non-adequacy”, since neither perception nor knowledge, in his view, actually conveys the things perceived or known. Reality comes up drenched in transcendence, and likewise thought has to span the “uncanny distance” that severs the subject from itself and every object from its own identity. Thus appear groundless an array of received views on the “reversibility” ascribed by Merleau-Ponty to the doublet “distance (...) vs. immediacy”. (shrink)

The centenary of the birth of Ludwig Wittgenstein provided an opportunity for recovering some of the great Wittgensteinian subjects, for re-examining them and for discussing their implications and relevance. This volume is the result of the interchange that took place in Girona among well-known scholars of Wittgenstein's work in different countries. The eleven contributions are organized into three main subjects: on Wittgenstein's method, on knowledge and meaning, on language and use. This volume is not only the result of the different (...) and mature reflexions of its authors, but in two cases it has also unfortunately become their last contribution to the subject. (shrink)

La tradition éthique en économie politique a été régénérée par l’Ecole de Salamanque, mais nous ne sommes pas habitués à associer le libéralisme aux scholastiques qui avaient élaboré une théorie du juste prix de validité universelle. Le marché a perdu sa dimension morale avec le rationalisme et, non dans une moindre mesure, à travers le biais religieux de la théorie de la valeur travail. Quand elle fut redécouverte en tant qu’origine véritable de la valeur, l’utilité ne recouvrit pas sa portée (...) morale, en raison du traitement mathématique qu’on lui réserva. Le rationalisme a supprimé toute conception d’évolution sociale en même temps qu’il a favorisé l’intervention. Cependant, dans cette ère de corruption, un retour à l’acception de sens commun des prix requiert, selon l’auteur, le franchissement d’une étape supplémentaire, celui de maintenir l’ancrage éthique du juste prix ou du prix du marché.The ethical tradition in political economy was regenerated by the School of Salamanca, but we are not used to associating liberalism with these Scholastics who built a theory of the just price with universal validity. The market lost its moral dimension with rationalism, not least through the religious bias of the labor theory of value. When rediscovered as the correct source of value, utility did not regain its former moral significance because of mathematical treatment. Rationalism has suppressed any concept of social evolution while promoting intervention, but, in the age of corruption, a return to the common sense of prices, the author argues, requires the further step of upholding the ethical standards of the just price or market price.

Chimpanzees follow the gaze of conspecifics and humans — follow it past distractors and behind barriers, ‘check back’ with humans when gaze following does not yield interesting sights, use gestures appropriately depending on the visual access of their recipient, and select different pieces of food depending on whether their competitor has visual access to them. Taken together, these findings make a strong case for the hypothesis that chimpanzees have some understanding of what other individuals can and cannot see. However, chimpanzees (...) do not seem nearly so skillful in the Gesture Choice and Object Choice experimental paradigms. Neither behavioral conditioning nor theory of mind explanations can account for these results satisfactorily. Instead this chapter proposes the idea that chimpanzees have the cognitive skills to recall, represent, categorize, and reason about the behavior and perception of others, but not their intentional or mental states, because they do not know that others have such states since they cannot make a link to their own. Human beings began their own evolutionary trajectory with these same skills, but then at some point in their evolution (probably quite recently) they began to understand that their own experience could serve as some kind of model for that of other persons. This allowed for even better prediction and control of the behavior of others and better communication and cooperation with them as well, and so it was an adaptation with immediate adaptive consequences that ensured its survival.

In this enlightening exploration of our nearest primate relatives, Michael Tomasello and Josep Call address the current state of our knowledge about the cognitive skills of non-human primates and integrate empirical findings from the beginning of the century to the present.

This paper reviews the development of socially responsible investment (SRI) in the Spanish financial market. The year, 1997 saw the appearance in Spain of the first SRI mutual fund, but it was not until late 1999, that major Spanish fund managers offered SRI mutual funds on the retail market. The development of SRI in the Spanish financial market has not experienced the high levels of development seen in other European countries, such as France or Italy, where interest in SRI began (...) during the same period. This paper presents an analysis of the impact of SRI mutual funds managed by Spanish fund managers comparing the evolution of managed assets and number of investors. We also analyse the investment strategies adopted by these funds, which mainly use negative screening criteria and the participation of non-governmental organisations as institutional investors. An analysis of the take up of socially responsible investment in the Spanish financial market shows majors deficits in this process. This is due to Spanish investors having limited sensitivity to social issues and knowledge of SRI, and a lack of development of SRI investment strategies, such as engagement or shareholder activism by fund managers. Furthermore, the take-up of SRI mutual funds in the Spanish financial market coincided with a fall in the stock market at the beginning of the 21st Century. We conclude with an analysis of the relationship between SRI and Corporate Social Responsibility (CSR). (shrink)

This article examines the relevance of a theory of the multinational state for the evaluation of claims for self-determination and secession. Considerations of ?ethnocultural justice? imply that the recognition of the multinational character of a state ? or the granting of some of the minority nations' demands ? is a matter of justice. If these requirements are not met, secession could be justified. Indeed, if secession needs a just cause (as it has been argued), a failure to build a truly (...) multinational arrangement can be a valid reason for a minority nation to secede. An approach like the one proposed would also contribute to the resolution of some of the key problems of the three main theories of secession and their appeals to nationalism, choice and remedial rights.

In recent years, scholars have increasingly dedicated their attention to analyse and reflect on the topic of leadership. However, the debate has often focused on the figure of the leader, as if being a leader were a self-sufficient function in itself, understood without finalities or independent of them. I would argue that leadership is not a position that can be assumed, but, rather, a relationship that is constructed. Similarly, the question of leaders has often given rise to a deconstruction of (...) its components, without any insight as to how the reality is put together. Leadership cannot be understood solely from a technical or instrumental perspective. It is not a mere relational skill that simply requires developing competencies. The exercise of leadership always includes—explicitly or implicitly—a connection with values. Therefore, developing leadership is impossible without a personal process that develops the person’s capacity for perception, learning, interiorisation, explicit sense-making and constructing meaning. These issues are truly important at a time in which the debate on business education and its contribution is completely open, targeting the very core of business education’s reason for being. Though open, the debate can only become a truly dynamic discussion if there is a real dialogue between the different positions and traditions. For this reason, this paper proposes an anthropological and non-denominational reading of some of the fundamental meditations found in the Spiritual Exercises of Saint Ignatius which could be used as a heuristic in the debate regarding what business schools propose. This paper represents an initial step in this direction, exploring some of the potentialities of the Spiritual Exercises for business schools that do not claim any religious tradition. (shrink)

En aquesta arrencada del segle XXI, en què la tecnologia ens afalaga i alhora ens domina, ens calen humanistes que ens ajudin a interpretar la realitat i a tenir criteris per a abordar-la. Josep Maria Puigjaner, l'autor d'aquest llibre, s'ha proposat apropar al lector, a través de la narració d'alguns retalls -reals o imaginaris- de les seves vides, la personalitat de vuit humanistes que ens transmeteren, durant el segle XX, la seva manera d'entendre la vida i l'home. Són escriptors (...) que mereixen el qualificatiu de clàssics, és a dir que parlen des d'una perspectiva interior, profunda i arrelada en el coneixement i en l'experiència del significat de la naturalesa humana i els seus ideals de futur.

In this paper, we review the conventional analyses of management control systems, to conclude, first, that the illusion of control can mislead managers into believing that everything can be controlled and monitored, and, second, that no incentive system based only on extrinsic rewards can motivate individuals properly. Then, we investigate the philosophical foundations of the basic assumptions that, implicitly or explicitly, are made about the nature of the acting person. Based on personalist phenomenology, we show how the development of technical (...) and moral values is crucial to the long-run survival of organizations. We end by offering some guidelines as to what control systems should be like in order to be compatible with the nature of human persons. (shrink)

As I see bus no. 29 approaching, I raise my arm. The bus stops, I take a few steps and get on it. This happens because the driver, having seen my arm raised, interpreted the gesture as a conventional expression of my wish to get on the bus. If it had been bus no. 17, I would not have raised my arm because I know that that bus follows quite a different route. This is not, of course, the end of (...) the story. I might also mention the reasons why I really wanted route 29, and so on. Fortunately, there is no need to go into the details. The important point is that in the explanation of this trivial set of actions I can quite naturally appeal to a number of mental states: perceptions, beliefs, interpretations, desires, etc. The previous story assumes, for instance, that.

This paper has a very limited scope: it just presents some eIements which may introduce us into a wider investigation on vague predicates. Thus, webegin by pointing out our general conception of Iogic (as a descriptive science of linguistic phenomena). After that, we build up our approach by considering characteristic functions and by trying to make useful the model of logical extension which applies to classical quantifiers.

The concept of convention has been used in different fields and from different perspectives to account for important social phenomena, and the legal sphere is no exception. Rather, reflection on whether the legal phenomenon is based on a convention and, if so, what kind of convention is involved, has become a recurring issue in contemporary legal theory. In this book, some of the foremost specialists in the field make significant contributions to this debate. In the first part, the concept of (...) convention is analysed. The second part reflects on whether the rule of recognition postulated by Hart can be understood as a convention and discusses its potential and limitations in order to explain the institutional and normative character of law. Lastly, the third part critically examines the relations between conventionalism and legal interpretation. Given the content and quality of the contributions, the book is of interest to those wanting to understand the current state of the art in legal conventionalism as well as those wanting to deepen their knowledge about these questions.

The last years of the 20th Century have been somewhat contradictory with respect to values like loyalty, trust or truthfulness. On the one hand, (often implicitly, but sometimes very explicitly), self-interest narrowly defined seems to be the dominant force in the business world, both in theory and in practice. On the other hand, alliances, networks and other forms of cooperation have shown that self-interest has to be at least "enlightened".The academic literature has reflected both points of view, but frequently in (...) an ambiguous way, since the concepts of loyalty and trust are somewhat elusive and equivocal. This paper attempts to analyze the concept of loyalty in depth, examining the different conceptions about the word that can be found in the literature. We begin by going to the management classics (specifically, Follett, Barnard and Simon), and we then turn to the anthropological approach of Pérez López (1993), with its built-in ethical analysis, and show how trust and loyalty are crucial to the development of organizations. We end by suggesting in what ways loyalty and trust can be created and fostered in organizations. (shrink)

Engineering ethics is usually focused on engineers’ ethics, engineers acting as individuals. Certainly, these professionals play a central role in the matter, but engineers are not a singularity inside engineering ; they exist and operate as a part of a complex network of mutual relationships between many other people, organizations and groups. When engineering ethics and engineers’ ethics are taken as one and the same thing the paradigm of the ethical engineer which prevails is that of the heroic engineer, a (...) certain model of the ideal engineer: someone both quite individualistic and strong enough to deal with all the moral challenges that could arise. We argue that this is not the best approach, at least today in our interrelated world. We have achieved a high degree of independence from nature by means of technology. In exchange for this autonomy we have become increasingly tied up with very complex systems to which we constantly delegate new tasks and powers. Concerns about safety keep growing everywhere due to the fact that now we have a sensitive awareness of the huge amount of power we are both consuming and deploying, thus, new forms of dialogue and consensus have to be incorporated at different levels, in different forums and at different times. Within these democratic channels of participation not just the needs and interests, but also the responsibilities and mutual commitments of all parties should be taken into account. (shrink)
