En el canto V del infierno de la Divina Comedia, el autor presenta diferentes ejemplos de condenados por la lujuria. En este trabajo se propone la clasificación de dichos personajes en dos categorías, por un lado, aquellos que someten la razón a la pasión erótica y, por el otro, aquellos que la someten a la pasión afectiva. Así mismo, se cuestionan los motivos por los cuales el autor florentino considera estas aproximaciones como transgresiones graves contra «el orden del amor». (...) A continuación, se lleva a cabo un análisis comparativo de estos dos tipos de amor presentes en dos obras que establecen una clara relación de intertextualidad con la Divina Comedia, a saber, la No-Divina Comedia de Zygmunt Krasinski y Don Juan en el infierno de Carlos Fisas. Se demuestra de este modo la amplitud de la influencia de este autor en diferentes épocas y espacios culturales, así como, su asombrosa universalidad. (shrink)

The First Letter of John is widely known for its famous affirmations concerning Christian love. This article, thanks to the application of the method of biblical rhetorical analysis, seeks to deepen the theme of love by offering an exegesis of 1Jn 1-10 where, for the first time in the Epistle, the expression «God is love» appears. The analysis of the text reveals that these ten verses, often broken up by commentators, form a coherent textual unity, not only because of their (...) internal composition, but also due to their meaning. Christian love, which finds its roots, its model and even its reason for being in the love of God revealed in his Son, is closely related to the faith and spiritual discernment which prevent us from being misled by «false prophets», especially those who deny the «carnality» of Jesus.

By relocating the author’s poetic impulse in the Arab world, Castro seeks to explain not only the Libro de buen amor’s open, “arabesque” structure—its spontaneous gliding from holy to profane, serious to comical, generic-abstract to concrete-sensible—but also the ambiguous nature of buen amor. For Castro, buen amor is the simultaneous compulsion toward spiritual transcendence and sexual fulfillment, best understood within the context of an Islamic theological system in which sexual desire is not categorically opposed to godliness.Not surprisingly, Castro’s scholarship was judged harshly by his critics as historical revisionism of the most pernicious sort, a deliberate erosion of those values and certainties that make it possible to read Spain as a full player in the march of Western civilization. Most vehement in his attack was Claudio Sánchez-Albornoz, who authored the two volumes of his España: Un enigma histórico (1956) as both an explicit defense against the “magnetic seduction” [1: 9] of Castro’s prose and a reaffirmation of national consciousness. Sánchez-Albornoz’s take on the Libro de buen amor falls neatly in line with the thinly disguised nationalism of his opus as a whole. He rejects soundly Castro’s claims of cultural hybridity in favor of a Libro de buen amor located safely on this side of the cultural “abyss” between Latin Christendom and the Islamic world. What is more, he resists the queernesses that spin out of Castro’s scholarship, the threat of contamination of the national character in unspeakable ways. If Spain had been exposed to the cultural proclivities of al-Andalus, Sánchez-Albornoz argues, so too would it have been exposed to al-Andalus’s “ambiguous” notion of love, a love “que no excluía las ‘amistades particulares,’ ni la sentimental inclinación, e incluso la pasión carnal, de varón a varón [that did not exclude ‘special friendships,’ nor sentimental inclination–and even carnal passion [End Page 104] –between one man and another]” [458].2 Here Sánchez-Albornoz slams the closet door shut by constructing Spain as the bastion of straight desire and Juan Ruiz as its virtual posterboy: “En el clérigo de Hita triunfaba la robusta, natural y simplista concepción heterosexual del amor de la Castilla de su época [There triumphed in the cleric of Hita a robust, natural, uncomplicated heterosexual concept of love characteristic of the Castile of his period]” [458–59].I begin with the Castro/Sánchez-Albornoz polemic because it exposes the presence and functions of “normativity” in Libro de buen amor studies throughout much of the twentieth century. With few exceptions, readings prior to Castro’s overlooked what was odd about the Libro de buen amor in order to engage in an obsessive archaeology of sameness, a plotting of conventional values and meanings that served to render the work as familiar, if not necessarily equal to other master works of the Western canon.

Este ensayo busca desarrollar una teoría del amor erótico basada en la tesis de Merleau-Ponty acerca de la reversibilidad de la carne. En el intento de distinguir el amor auténtico del amor romántico, y de elaborar el rol del conocimiento carnal que responde a la ansiedad erótica, este trabajo está específicamente dirigido hacia los aspectos cognitivos del amor sexual. Los antiguos temas griegos de la mímesis y de la nobleza (to kalón) son redefinidos mediante los (...) conceptos de la reversibilidad y la transferencia de los esquemas corporales, para generar un entendimiento teórico de los roles de la percepción y la encarnación en el desdoblamiento histórico de la incorporeidad erótica y revelar los valores en él implícitos.

The article deals with the theme of love in St. Augustine, highlighting how the Bishop of Hippo himself evolved in his own life from carnal and worldly loves to the love of God, as it appears fundamentally in his Confessions. In order to understand the dynamics of love, the article offers a brief summary of the Augustinian anthropological scheme. Some texts from the In epistulam Iohannis ad Parthos tractatus and the In Iohannis euangelium tractatus are also highlighted in order (...) to corroborate the conclusions of the article. (shrink)

This paper situates Einstein's theory of relativity within broader networks of communication. The speed of light, explained Einstein, was an unsurpassable velocity if , and only if , it was considered in terms of »arbitrary« and »voluntary« signals. Light signals in physics belong within a broader set of signs and symbols that include communication and military signals, understood by reference to Helmholtz, Saussure, media philosophies from WWII to '68 (Lavelle, Ong, McLuhan) and Derrida. Once light signals in physics are considered (...) in relation to semaphore, print, telegraph, radio, computers and tape recorders, Kittler and Habermas provide us with conflicting ways for understanding science and technology, rationality and consensus. We conclude with a study of »flash and bang« in popular accounts of relativity theory to understand the role of theoretical science in the transmission of information and violence. (shrink)

Building a meaningful model of biological regulatory network is usually done by specifying the components and their interactions, by guessing the values of parameters, by comparing the predicted behaviors to the observed ones, and by modifying in a trial-error process both architecture and parameters in order to reach an optimal fitness. We propose here a different approach to construct and analyze biological models avoiding the trial-error part, where structure and dynamics are represented as formal constraints. We apply the method to (...) Hopfield-like networks, a formalism often used in both neural and regulatory networks modeling. The aim is to characterize automatically the set of all models consistent with all the available knowledge. The available knowledge is formalized into formal constraints. The latter are compiled into Boolean formula in conjunctive normal form and then submitted to a Boolean satisfiability solver. This approach allows to formulate a wide range of queries, expressed in a high level language, and possibly integrating formalized intuitions. In order to explore its potential, we use it to find cycles for 3-nodes networks and to determine the flower morphogenesis regulatory network of Arabidopsis thaliana. Applications of this technique are numerous and concern the building of models from data as well as the design of biological networks possessing specified behaviors. (shrink)

Amor Masovic, responsable de la commission de recherche des disparus en Bosnie-Herzégovine et ancien responsable de la commission pour l’échange des prisonniers pendant la guerre de 1992-1995, nous présente ensuite un tableau accablant des disparitions dans les guerres récentes en ex-Yougoslavie, et des pratiques pour faire en sorte que ceux-ci ne soient ni retrouvés ni, encore moins, identifiés (d’où des fosses communes de deux types : « primaires » – où les corps furent enterrés initialement – et « secondaires (...) » – où ces mêmes corps furent ré-enterrés, souvent démembrés, après avoir été déterrés pour être dispersés et moins aisés à repérer). 28 000 des 40 000 disparus ex-Yougoslaves relèvent du conflit en Bosnie et sont à 95 % des civils protégés par les conventions de Genève. Sur les 280 charniers identifiés la plupart se trouvaient à l’arrière et non sur le front et les disparitions sont datables à des périodes de non-combat. Le but de la commission est donc d’abord de retrouver et identifier les morts pour « faire savoir » et permettre le deuil (puisque la barbarisation qui a été exercée est double : contre les victimes et contre leurs familles qui ne peuvent « vivre » tant qu’elles n’ont pas de certitude). En outre, faute de disposition légale et d’une absence de droit spécifique des disparus personne ne peut être incriminé pour une disparition devant le TPIY où les « disparus » ne sont donc pas représentés. Amor Masovic tire quatre conclusions de son exposé : 1) la barbarie exprimée aujourd’hui est pour partie un résultat des manques de la justice à l’égard des crimes de guerre de la seconde guerre mondiale ; 2) la guerre contre les civils augmente en même temps qu’augmentent les dispositions internationales contre ces exactions qui restent donc purement formelles ; 3) en Bosnie, la barbarisation s’est exercée sur les corps des victimes de façon redoublée puisque l’anéantissement des preuves du crime fait que la mort n’est pas une vraie fin. D’où une forme particulière de barbarisation d’après-guerre ; 4) seul élément plus « positif » : en Bosnie des échanges de prisonniers eurent lieu pendant la guerre sans attendre la fin du conflit ce qui est rarissime et va au-delà des exigences posées par les conventions de Genève en matière de libération des prisonniers.

We use a lab experiment to examine whether and how leaders influence workers’ (un)ethical behavior through financial reporting choices. We randomly assign the role of leaders or workers to subjects, who can choose to report an outcome via automatic or self-reporting. Self-reporting allows for profitable and undetectable earnings manipulation. We vary the leaders’ ability to choose the reporting method and to punish workers. We show that workers are more likely to choose automatic reporting when their leader voluntarily does so and (...) can assign punishment. Even workers who choose self-reporting tend to cheat less when their leader chooses automatic reporting. Nonetheless, most leaders do not opt for automatic reporting in the first place: they often choose self-reporting and punish workers who rather choose automatic reporting. Collectively, our results reveal a dual effect of leadership on ethical behaviors in organizations: workers behave more ethically if their leader makes ethical choices, but often leaders do not make ethical choices in the first place. Hence, leading by example can backfire. (shrink)

The inclusion of animals in research studies involves a great responsibility to ensure animal welfare within the relevant ethical and legal frameworks. This study aimed to review compliance with the ARRIVE Essential 10 requirements and the ethical oversight of animal behaviour and welfare studies in farm animals. Three journals and a total of 133 articles were reviewed for compliance with the ARRIVE Essential 10 items and criteria. Each article obtained a final score according to whether or not each criterion was (...) met within each item. Likewise, ethical declaration in each article was recorded. Chi-square test and linear models were built to assess associations between the ethical statement presentation and the final ARRIVE Essential 10 score with the country, the species, and the journal. We found that 15% of the articles did not present an ethical statement. The journal with the highest impact factor and the countries of the Global South presented an ethical statement more frequently. Regarding the Essential 10, the item with the lowest agreement score was ‘Blinding’ and the one with the highest agreement was ‘Outcome Measures’. Also, significant differences were found between journals in terms of the Essential 10 score. Essential 10 provides relevant information that allows reviewers and readers to identify possible welfare risks and the validity of the results in animal welfare science publications. (shrink)

The starting point for the following reflections comes from Jacques Roger’s monumental work, Les sciences de la vie dans la pensée française du XVIIIe siècle. I hope my remarks may cast some light on a problem that has long remained obscure, and doubtless was to Buffon himself: the status of matter in general and the relation of brute to organic matter in particular.

Humankind is currently witnessing, and shaping, the most significant and rapid paradigm shift in human history - a paradigm shift of major demographic, economic, ecological, and geo-political dimensions. For the first time in human history - we are faced not with just one crisis - but a confluence of several crises; crises that are not related to a single tribe or community - a single nation -or a single region of the world - but are each global in scale. To (...) meet the challenges of these global crises will require an equally historic paradigm shift; a paradigm shift with a strong environmental ethic that restores ecological balance and integrity to our failing ecosystems, and that addresses the critical issue of climate change; a paradigm shift toward an economic system that brings about an end to poverty — and a paradigm that brings an end to war as a means to solving conflict, as it is only through a global family in harmony and peace with itself, that we can solve the unprecedented global issues facing our one common home, planet earth - and our one common future as a global family. The travel and tourism industry has, and will continue to play a vital and leading role toward this paradigm shift, and as the world's largest industry involving virtually every nation in the world — will be the central pillar of a Peace through Commerce movement. The dramatic growth of tourism in the past 60 years is one of the most remarkable economic and social phenomena of our time. The industry has grown from a total of 25 million international arrivals in 1950 to a projected 1 billion international arrivals in 2010, and a further projection to 1.6 billion by 2020. Beginning with the emergence of "Ecotourism" in the late 1980' s, there are an increasing number of tourism market segments which fall within a broad category that can be called "Peace Tourism," and classified within a framework that includes peace within ourselves, peace with others, peace with nature, peace with past generations, peace with future generations, and peace with our Creator. Since its birth in 1986, the International Institute for Peace through Tourism (IIPT) has been promoting these values of tourism together with its vision of Travel and Tourism as the world's first "Global Peace Industry" - an industry that promotes and supports the belief that every traveler is potentially an "Ambassador for Peace." This "higher purpose of tourism" includes the key role of tourism in promoting international understanding and collaboration among nations; environmental protection and preservation of biodiversity; enhancing cultures and valuing heritage; contributing to sustainable development and poverty reduction; and healing wounds of conflict.

Contrasting the conflicting positions of Fink and Žižek, this article opens and closes with the question: is feminine jouissance ineffable? It solves the mystery of why Lacan associates the Other jouissance with women and presents an account of phallic and the Other jouissance informed by the work of Breuer and Freud. It argues that the satisfactions of Lacan’s feminine subject bear striking affinity to those of the hysteric, while phallic jouissance affords the same sort of enjoyment as that of Freud’s (...) obsessional neurotic. And, while “real” experiences make one lose one-self and may not be represented by one who was absent, this is not to say that we cannot shed light on characteristically feminine pleasure/pains.

Ezzence is the first smartphone-controlled olfactometer designed for both day and night conditions. We discuss the design and technical implementation of Ezzence and report on a study to evaluate the feasibility of using the device in home-based sleep environments. The study results show that participants were satisfied with the device and found it easy to use. Furthermore, participants reported a significant improvement in sleep quality when using the device with scent in comparison to the control condition, as well as better (...) mood the following morning and shorter time to sleep onset. The device is integrated with a wearable EEG and real-time sleep staging algorithm to release scent during specific sleep stages, which is important for certain use cases. Ezzence can be used for several applications, including those that require scent triggered day and night. They include targeted memory reactivation, longitudinal health treatments, therapy, and mental or physical exercises. Finally, this article proposes an interaction framework to understand relationships between scents and environments based on proxemic dimensions and passive or active interactions during sleep.

This article introduces some soft computing methods generally used for data analysis and flow pattern detection in fluid dynamics. These techniques decompose the original flow field as an expansion of modes, which can be either orthogonal in time, or in space or in time and space, or they can simply be selected using some sophisticated statistical techniques. The performance of these methods is tested in the turbulent wake of a wall-mounted square cylinder. This highly complex flow is suitable to show (...) the ability of the aforementioned methods to reduce the degrees of freedom of the original data by only retaining the large scales in the flow. The main result is a reduced-order model of the original flow case, based on a low number of modes. A deep discussion is carried out about how to choose the most computationally efficient method to obtain suitable reduced-order models of the flow. The techniques introduced in this article are data-driven methods that could be applied to model any type of non-linear dynamical system, including numerical and experimental databases. (shrink)

The problem of stability in population dynamics concerns many domains of application in demography, biology, mechanics and mathematics. The problem is highly generic and independent of the population considered (human, animals, molecules,…). We give in this paper some examples of population dynamics concerning nucleic acids interacting through direct nucleic binding with small or cyclic RNAs acting on mRNAs or tRNAs as translation factors or through protein complexes expressed by genes and linked to DNA as transcription factors. The networks made of (...) these interactions between nucleic acids (considered respectively as edges and nodes of their interaction graph) are complex, but exhibit simple emergent asymptotic behaviours, when time tends to infinity, called attractors. We show that the quantity called attractor entropy plays a crucial role in the study of the stability and robustness of such genetic networks. (shrink)

ZUSAMMENFASSUNGDie Auseinandersetzung mit der Praxis des Bittgebets stellt keine Randthematik bei der Reflexion des theistischen Glaubens dar, sondern ist von erheblicher systematischer und existentieller Bedeutung. Eine rege Debatte über die Sinnhaftigkeit des Bittgebets ist gegenwärtig in der angelsächsischen Religionsphilosophie in Gang. Die Untersuchung präsentiert und würdigt kritisch die aktuellen Entwürfe zum Bittgebet von Eleonore Stump und Keith Ward. Beide Autoren erachten die traditionelle Konzeption des Bittgebets bei Thomas von Aquin für unbefriedigend und entwickeln ihre eigenen Entwürfe in Absetzung vom Aquinaten. (...) Da weder Stump noch Ward eine detaillierte Analyse des Bittgebets bei Thomas vorlegen, wird dieses in einem ersten Schritt vorgestellt. In einem zweiten Schritt erfolgt die Auseinandersetzung mit den von Stump und Ward vorgebrachten Einwänden. Abschließend werden Stärken und Schwächen des thomanischen Entwurfs erhoben.SUMMARYWhat petitionary prayer is about is not a marginal topic for theism but bears considerable systematic and existential value. A lively debate about the meaningfulness of petitionary prayer is under way in contemporary angloamerican philosophy of religion. The paper presents and discusses the accounts of petitionary prayer put forward by Eleonore Stump and Keith Ward. Both scholars consider the traditional account of petitionary prayer proposed by Thomas Aquinas as unsatisfactory and develop their own outlines in opposition to Aquinas. Regrettably neither Stump nor Ward provide us with a detailed analysis of Aquinas's understanding of petitionary prayer. Therefore the paper first presents at length the account of Aquinas. Then the objections Stump and Ward put forward against Aquinas are examined. Finally, strengths and weaknesses of Aquinas's understanding of petitionary prayer are worked out. (shrink)
