Tourism is capable of distributing wealth and participating substantially in the economic development of many countries. However, to ensure these benefits, the planning, management, and monitoring of a sustainable offer become crucial. Despite the increasingly widespread attention to sustainability in this sector, however, the concept of sustainable tourism still appears fragmented and fuzzy. The theoretical frameworks used in many studies often reduce sustainability to its environmental or social aspects and consider such pillars as separate issues. Furthermore, although most studies (...) acknowledge that a potentially wide number of stakeholders play a role in sustainable tourism production, they have so far focused on host communities, tourism producers, or tourists themselves independently. Fewer explorations have addressed simultaneously different stakeholders, their perceptions of sustainable tourism experience, and the various concerns and tensions that may arise. This study aims to investigate sustainability issues in tourism by considering the voices of two relevant stakeholders involved in “co-producing” the tourism experience: tourists and tour operators. Based on a qualitative study conducted in Italy, the article critically discusses how travelers and tour operators craft the sustainability idea, the implicit assumptions that rely on their different perspectives, and their practical implications. The results highlight four different narratives on sustainable tourism, which are related to different assumptions on sustainability and actions legitimated to generate sustainable value. Finally, the article offers insights into how to develop a more holistic and critical approach to sustainable tourism through education and communication. (shrink)

The following essays focus on one of the most important figures in the religious history of the later middle ages. Giovanni of Capestrano is in one sense familiar to many, above all to scholars and students of Franciscan history. The story of the friar from Abruzzo, one of the 'four pillars' of the Observance, appears in every standard account of the Order's history: his career as a jurist, his conversion and tutelage under Bernardino, his fierce advocacy for the Observants, (...) his long preaching tour north of the Alps and his role in the crusade of 1456. And for centuries that story has been the subject of progressively more refined scholarship, from Luke Wadding in the seventeenth century to Johannes Hofer and... (shrink)

Scientific knowledge is no longer transmitted solely through a one-way channel of communication from scientific communities to `lay' readers through the knowledge transmission `chain'. Communication between the two communities has now been extended into media and everyday social discourse where it crops up in news debates about issues such as public health and food safety. In this process, scientific academic discourse has lost much of its original form. This article examines part of the current research at the Centre de recherche (...) sur les discours ordinaires et spécialisés. It provides evidence of new discursive forms adopted by science in media and social discourse, such as the emergence of enunciative standpoints, the redefinition of the role of the journalist as mediator between science and the general public, the use of specific forms of intertextuality and the interweaving of scientific elements in general social discussions. This research on new data implies renewed definitions of certain concepts used in linguistic descriptions: discursive meaning and signification, interdiscursive memory bank, etc. These recent forms of discourse have brought about a change in the status of science so that science has now become an object of debate in the public arena — a sign of its crucial social role.

RESUME Dans cet article, on aborde le champ de la vulgarisation scientifique en mettant l'accent sur les différentes sphères d'activité langagière qui s'y croisent. On rappelle d'abord le modèle classique et linéaire de la diffusion scientifique avant de montrer le déplacement qui s'est ensuite produit avec l'intervention des médias traditionnels, qui, notamment lors d'événements scientifiques, ont fait dialoguer différentes communautés langagières. On aborde enfin les changements apportés par les nouveaux outils technologiques dans des formes de participation et de prise de (...) parole qu'autorise l'internet.ABSTRACT This paper deals with the field of popular science with a focus on the different linguistic spheres that intersect it. It starts by reviewing the classical linear model of scientific dissemination. The authors then show the displacement that took place with the involvement of traditional media that established a dialogue between different language communities, in particular for scientific events. Finally, the changes to forms of participation and speech resulting from new technological tools and made possible by the Internet are presented.RESUMO O presente artigo aborda o campo da divulgação científica através das diferentes esferas de atividade linguageira que nele se cruzam. Evocaremos incialmente o modelo clássico e linear da divulgação científica, antes de apresentarmos o deslocamento produzido, em seguida, pela mídia tradicional, que possibilitou o diálogo entre diferentes comunidades linguageiras, especialmente em acontecimentos científicos. Mostraremos finalmente as modificações trazidas pelas novas ferramentas tecnológicas nas formas de participação e de tomada da palavra proporcionadas pela Internet. (shrink)

Ce texte est une petite histoire de la consultation conjugale durant ces cinquante dernières années, avec l’idéologie de ses débuts, les recherches théoriques, cliniques et méthodologique du conseil conjugal. La pression de la demande et son évolution est mise en parallèle avec les recherches cliniques ayant amené à proposer des thérapies de couple. Celles-ci à leur tour nous renseignent sur les difficultés des couples actuels, reflétant l’évolution des valeurs de la société.

Im Kontext der Spannung zwischen Kritik und Erneuerung der Metaphysik entfaltet der christliche Philosoph Ferdinand Ulrich eine Metaphysik des Seins als Gabe, in der nicht Gabe statt Sein, sondern Sein als Gabe konsequent gedacht wird. Geschichte und Existenz werden Schauplatz einer Ontodramatik, bei der es in der dialogischen Selbstverantwortung und in der Verantwortung fur die Welt um die Zustimmung zur oder die Verweigerung der Liebe als Sinn des Seins geht. Unter den vielfaltigen Stationen dieses dialogisch vorgehenden Denkens werden im vorliegenden (...) Band die Gesprache mit Hegel, Heidegger und Schelling aufgenommen. Entlang dieser Gesprache rekonstruiert die Autorin diesen metaphysischen Ansatz, fragt nach seiner inneren Logik und seinem epistemologischen Status und sucht Moglichkeiten des Nachvollzugs.

Most studies on the choices, motivations and behavior of investors consist of segmentations focused on socio-demographic characteristics such as age, income, education level, etc. Such approaches seem to simplify, even mutilate, reality by aggregating data about observable variables and considering investors as homogeneous groups. These perspectives are inspired by a scientific approach that consists of separating in order to better understand the observed phenomena. By considering individual as a “homo economicus”, that is to say, a rational and autonomous individual who (...) makes decisions motivated by material gains, these studies fail to recognize all the complexity that shapes human behavior. This paper argues that to understand the behavior and choices of investors in regards to socially responsible investing, we must consider social investors as complex individuals. In addition, we should take into account influence that the institution may exercise throughout the role of advisors and SRI promotion strategies. Our research builds on a multidimensional approach that explores to what extent demographic, environmental, social and governance issues, the trade-offs between financial return and social values, the attitudes and the role of the institution influence the decisions of individual social investors. Moreover, it adopts a more open approach by exploring the characteristics and behaviors of individual social investors in relation to those of conventional investors. Our research provides evidence from the Desjardins Fund. Qualitative and quantitative data gathered by Desjardins from online surveys are subjected to bivariate and multivariate analyses and are complimented by ten semi-structured interviews with managers, analysts, and advisors who provided further insight into SRI investment behavior and choice. The results show that while demographic characteristics still remain important in understanding the behavior and attitudes of social investors, it is their social values, ESG issues, financial return considerations and the role played by the institution in mediating investment decisions that are significantly associated with SRI portfolios. Our research highlights the complexity surrounding the phenomenon of SRI and has several implications both in terms of theory and practice. (shrink)

This article will investigate the issue of accessing benxin 本心 (original mind), subsequent operation from Self and, in that process, union with the greater universe or benti 本体 (original substance)—a state expressed in the West as cosmic consciousness. It is proposed that this allows one to participate as a partner in the creative process of one’s own life and the surrounding world. The equally important question of how to gain contact with original mind will also be addressed, as well as (...) the consequences of doing so with regard to the human condition. The concept of original thought is introduced, being important here as it is held to be that thought which is generated in the pure condition of original mind, devoid of influence from finite physical existence.

Le handicap transforme la vie du couple et de la famille. La surcharge psychique qu’il implique pour tous les membres de celle-ci et les défenses mises en place révèlent les fragilités du couple et rendent nécessaires un travail d’élaboration, principalement de certaines collusions sur lesquelles s’était construit le couple. La régression de fonctionnement que le traumatisme provoque peut amener le thérapeute à se demander si ce fonctionnement révèle la structure du couple ou s’il est une défense. Ce fut en tout (...) cas l’hypothèse qui a soutenu le travail clinique dans le cas présenté. (shrink)

Dans un premier cas, le travail du contre-transfert en thérapie de couple met au jour les traumatismes mis en résonance dans le choix amoureux et leur élaboration. Deux autres thérapies montrent comment les traumatismes des générations précédentes peuvent être mis en figuration dans l’organisation du couple et être mobilisés dans le transfert.

La rencontre des consultants et des thérapeutes se fait sur un choc de leurs croyances au couple. Cette question est interrogée à partir des formulations des consultants et des thérapeutes sur le couple, sur leur couple. Elle introduit à ce qu’est un couple pour l’auteur, un organisateur du psychisme, une matrice de subjectivité.

Pour vivre en couple et rester soi, un écart entre les conjoints est nécessaire. La vie actuelle, quand le tiers est peu ou mal intériorisé, permet aux couples de vivre selon des situations sociales différentes – et variables dans le temps. Parmi celles-ci, la non-cohabitation. Un exemple clinique montre les étapes par lesquelles sont passés les conjoints d’un jeune couple au cours de la thérapie, de la vie en groupe à la non-cohabitation. Quand ils se séparent, ce n’est pas pour (...) se séparer, mais pour expérimenter une relation conjugale pouvant les conduire à un couple psychique dans lequel chacun peut se sentir exister. L’article montre comment ces étapes leur ont permis d’approfondir et de transformer leur relation. (shrink)

Malian farmers’ traditional system for managing seed of sorghum, an indigenous crop of vital importance for food security and survival, can be conceptualized as a commons. Although this system maintains a wide range of varieties and helps ensure access to seed, its ability to create and widely disseminate new varieties to meet evolving opportunities and challenges is limited. A network of farmer groups, public breeding programs, and development organizations collaborating in decentralized creation and dissemination of sorghum varieties in Mali is (...) examined regarding (1) how the network developed and what activities it conducts; (2) the resulting varietal diversity, varietal performance and organizational models; and (3) the elements of the traditional seed system that were maintained, strengthened or transformed. A single-case study approach was used that relies on published literature, official catalogues of released varieties and a database of farmer seed-cooperative requests for foundation seed. The functioning of the network and its varietal-, seed-, and organizational- outcomes are documented and the elements of the traditional sorghum seed system that are maintained or strengthened are analyzed. The evolution of the network’s reliance on commoning as a social process and its strengthening of core Seed Commons features are discussed with a view to the network’s contributions to targeted development outcomes and potential replicability. The case demonstrates how creating a framework for collaboration, enabling actors and organizations to take on collective responsibility while maintaining distributed decision-making at local level, opens opportunities for transforming farming- and food-systems towards sustainability and resilience.

Over the past fifteen years there has been a considerable amount of debate concerning what theoretical population dynamic models tell us about the nature of natural selection and drift. On the causal interpretation, these models describe the causes of population change. On the statistical interpretation, the models of population dynamics models specify statistical parameters that explain, predict, and quantify changes in population structure, without identifying the causes of those changes. Selection and drift are part of a statistical description of population (...) change; they are not discrete, apportionable causes. Our objective here is to provide a definitive statement of the statistical position, so as to allay some confusions in the current literature. We outline four commitments that are central to statisticalism. They are: 1. Natural Selection is a higher order effect; 2. Trait fitness is primitive; 3. Modern Synthesis (MS)-models are substrate neutral; 4. MS-selection and drift are model-relative. (shrink)

This article discusses the integrative function frequently assigned to festive events by scholars. This function can be summed up in a proposition: experiencing similar emotions during collective gatherings is a powerful element of socialization. The article rejects this oft-developed idea according to which popular fervor could be an efficient tool to measure civic engagement. It raises the following question: what makes enthusiasm “civic”, “patriotic”, “republican” or simply “political”? Based on a study of French presidential tours in France from 1888 to (...) 2007, this article casts a different light on the topic. The enthusiasm of the crowds interacting with the successive French presidents is not civic because an inquiry may find “patriotism” into participants’ minds. It can be called civic simply because the forms and meaning of the festive jubilation, which may be summarized into the formula: “if spectators applaud, it means they support,” necessarily preexist its multiple manifestations.

The critical and polemic receptions of the work of Loïc Wacquant has been extensive, but to a large extent focused on specific works and colored by professional specialty, that is, in a word: fragmented. In counteracting that fragmented response, the article sheds light on the undercurrents in Wacquant’s works by stressing four prominent and consistent features: his heritage from (and updating of) Bourdieu; his emphasis on and constant practice of theory (implicit as well as explicit); the distinct ethos with which (...) he addresses political sociology (in the dual form of a sociology analyzing the effects of the political productions of populations categories and a so-called ‘civic sociology’); and finally, the persistent and ubiquitous critique of everything in existence – a thematic indicator permeating each and every one of his works. Thus the article proposes a unifying reading of Wacquant as an interpretation advocating revitalization of a critical social science. (shrink)

This article first addresses the question of “why” we teach business ethics. Our answer to “why” provides both a response to those who oppose business ethics courses and a direction for course content. We believe a solid, comprehensive course in business ethics should address not only moral philosophy, ethical dilemmas, and corporate social responsibility – the traditional pillars of the disciple – but also additional areas necessary to make sense of the goings-on in the business world and in the (...) news. These “new pillars,” that we advocate include moral psychology, organizational design and behavior, motivational theory, and a unit on how society, business, and law interact. This last unit builds upon the work of Francis P. McHugh (1988) who urged an integration of “disciplines related to business ethics.” Our seventh pillar would encompass an integration of law, socio-political theory, and policy to demonstrate how business helps construct its own regulatory framework. The concluding recommendation is for a comprehensive “Seven Pillars” of business ethics approach. (shrink)

This book argues that the philosophical history of India contains a tradition of skepticism about philosophy represented most clearly by three figures: Nāgārjuna, Jayarāśi, and Śrī Harṣa.

2007 will be remembered as the year in which the Tour de France died. Race leader and likely eventual winner, Michael Rasmussen, was eliminated near the end on an allegation of doping. Since the 1960s, the idealistic drug crusaders have been on a mission to reverse the course of history, and eliminate drugs from the sport. But this “zero tolerance” strategy to drugs has failed, as 2007's Tour spectacularly showed. Only around 10–15% of professional athletes are drug tested. (...) Currently, it is illegal to use erythropoietin (EPO) or blood doping to move your haematocrit from 48 to 49% even though some people will have a normal level of 49%. A regulated permissive policy would paradoxically reduce risk to athletes. The present system creates an environment of risk to the athlete. A rational policy on doping would allow safe performance‐enhancing interventions which are consistent with the spirit of a particular sport. (shrink)

This festschrift volume is dedicated to Boris (Boaz) Trakhtenbrot on the occasion of his 85th birthday. For over half a century, Trakhtenbrot has been making seminal contributions to virtually all of the central areas of theoretical computer science. He is universally admired as a founding father and long-standing pillar of the discipline of computer science. On Friday, 28 April 2006, the School of Computer Science at Tel Aviv University held a “Computation Day Celebrating Boaz (Boris) Trakhtenbrot's Eighty-Fifth Birthday”. As a (...) follow-up to that event, his students and colleagues were asked to contribute to a volume in his honor and in recognition of his grand contributions to the field. The book opens with two historical overviews and a bibliography. These are followed by 33 thoroughly reviewed technical contributions. The broad range of topics covered include mathematical logic, logics for computer science, mathematics for computer science, automata and formal languages, asynchronous computation, semantics of programming languages, verification, and software engineering. This tapestry of subjects stands as testimony to the vast scope of Trakhtenbrot's achievements and the profound influence he has had on the field. (shrink)

What enables individually simple insects like ants to act with such precision and purpose as a group? How do trillions of individual neurons produce something as extraordinarily complex as consciousness? What is it that guides self-organizing structures like the immune system, the World Wide Web, the global economy, and the human genome? These are just a few of the fascinating and elusive questions that the science of complexity seeks to answer. In this remarkably accessible and companionable book, leading complex systems (...) scientist Melanie Mitchell provides an intimate, detailed tour of the sciences of complexity, a broad set of efforts that seek to explain how large-scale complex, organized, and adaptive behavior can emerge from simple interactions among myriad individuals. Comprehending such systems requires a wholly new approach, one that goes beyond traditional scientific reductionism and that re-maps long-standing disciplinary boundaries. Based on her work at the Santa Fe Institute and drawing on its interdisciplinary strategies, Mitchell brings clarity to the workings of complexity across a broad range of biological, technological, and social phenomena, seeking out the general principles or laws that apply to all of them. She explores as well the relationship between complexity and evolution, artificial intelligence, computation, genetics, information processing, and many other fields. Richly illustrated and vividly written, Complexity : A Guided Tour offers a comprehensive and eminently comprehensible overview of the ideas underlying complex systems science, the current research at the forefront of this field, and the prospects for the field's contribution to solving some of the most important scientific questions of our time.

Over three centuries after the 1711 discovery in the choir of Notre-Dame in Paris of a square-section stone bas-relief with depictions of several deities, both Gaulish and Roman, the blocks comprising it were analyzed as a symbol of Parisian power, if not autonomy, vis-à-vis the Roman Empire. Variously considered as local, national, or imperial representations, the blocks were a constant object of admiration, interrogation, and speculation among antiquarians of the Republic of Letters. They were also boundary objects – products of (...) the emergence of a Parisian archeology dated from 1711. If this science reflected the tensions and ambiguities of a local regime of knowledge situated in a national context, it also helped to coordinate archeological work between different institutions and actors. This paper would like to assess the specific role played by the Pillar of the Boatmen as a fetish object in this process. To what extent could an archeological artifact influence this reshaping of urban representation, this change of scales? By following the three-century career of the pillar’s blocks as composite objects, which some have identified as merely stones or a column, it is possible to understand the multiple dimensions that defined the object as archeological – as an artifact that contributed to the relocating of the historical city center – and the multiple approaches that transform existing remains into knowledgeable objects.
