Sustainable tourism: a new retoric in the language of tourism
No full textWithin the framework of French Discourse Analysis, the author tries to work out the ethos of discourse inherent to the self-presentation of hosts and travellers as well as to the description of the locations and their sceneries
Travellers’ memories: the image of places from literature to blog chatter
No full textStarting from the assumption that texts produced in the tourist sector are a form of discourse, the paper focuses on narrative texts and singles out two sub-genres, namely travel literature proper and reports published on tourism websites. The corpus, comprising texts referring to India, is analysed with mainly qualitative methodology. Four aspects are considered in detail: enunciation and the author / reader relationship; the presence of subjective vs objective points of view; the time-space dimension; the exploitation of shared knowledge and stereotypes. The analysis reveals that the two sub-genres share some textual features and, despite their different literary value, both contribute to the construction of an image of the destination which can play a signifi cant role in tourism promotion
Thinking in systems: a primer
No full textIn the years following her role as the lead author of the international bestseller, "Limits to Growth"-the first book to show the consequences of unchecked growth on a finite planet- Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001. Meadows' newly released manuscript, "Thinking in Systems", is a concise and crucial book offering insight for problem solving on scales ranging from the personal to the global. Edited by the Sustainability Institute's Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders across the globe consider critical for 21st-century life. Some of the biggest problems facing the world-war, hunger, poverty, and environmental degradation-are essentially system failures. They cannot be solved by fixing one piece in isolation from the others, because even seemingly minor details have enormous power to undermine the best efforts of too-narrow thinking. While readers will learn the conceptual tools and methods of systems thinking, the heart of the book is grander than methodology. Donella Meadows was known as much for nurturing positive outcomes as she was for delving into the science behind global dilemmas. She reminds readers to pay attention to what is important, not just what is quantifiable, to stay humble, and to stay a learner. In a world growing ever more complicated, crowded, and interdependent, "Thinking in Systems" helps readers avoid confusion and helplessness, the first step toward finding proactive and effective solutions

No full text10 p.-6 fig.-3 tb.Functional pairing between cellular glyco-con-ju-gates and tissue lectins like galectins has wide (patho)physio-logical significance. Their study is facilitated by non-hydrolyzable deri-va-tives of the natural O-glycans, such as S- and Se-glycosides. The latter en-able extensive analyses by specific 77 Se NMR spectroscopy, but still remain under-explored. By the example of seleno--digalac-to-side (SeDG) and the human galectins 1 and 3, we evaluate diverse 77 Se NMR detec-tion methods and pro-pose selec-tive 1 H, 77 Se hetero-nuclear Hartmann-Hahn transfer for efficient use in com-peti-tive NMR screening against a seleno-glycoside spy ligand. By fluores-cence aniso-tropy, circular dichroism, and isothermal titra-tion calori-metry (ITC) we show that affinity and thermodynamics of SeDG bind-ing by galectins are similar to thiodi-galac-toside (TDG) and N-acetyl-lactos-amine (LacNAc), con-firm-ing that Se substitution has no major impact. ITC data in D 2 O vs. H 2 O are similar for TDG and LacNAc binding by both galectins, but a solvent effect, indicating solvent rearrangement at the binding site, is hinted for SeDG and clearly observed for LacNAc dimers with extend-ed chain length.We are much indebted to L. Szilágyi (University of Debrecen,Hungary) for kindly providing selenoglycosides for this study. We are grateful for inspiring discussions to Drs. B. Friday, A. Leddoz and A. W. L.

Madonna House: A Catholic Social Settlement in Lower Manhattan
No full textWhat is a social settlement? The author in the course of this study has reviewed numerous interpretations of a social settlement. It is her impression that the most clear cut definition is to be found in the Encyclopedia Britannica.The Industrial Revolution, in England? brought with it a centralization of labor. There was a movement from the farm to the factory; cities of magnitude began to develop. These cities in turn gave rise to deplorable living conditions. Laborers of low income bracket, were forced to reside in depraved neighborhoods. The shift from the farm to the factory was a difficult adjustment for the working man to make. He was no longer able to work at his own pace; he became a spoke in the wheel of progress. His hours at the factory were long; with every ounce of his physical strength, he earned his merger wage. If he found time for leisure, his earnings did not permit him to indulge in recreational luxuries. Life in the city was hard
Travellers’ memories: the image of places from literature to blog chatter
No full textA partir del supuesto de que los textos producidos en el sector turístico constituyen formas discursivas, este artículo se centra en los relatos de experiencias personales de viaje y, en particular, en dos subgéneros: la literatura de viaje y los relatos publicados en las páginas web de turismo. El análisis del corpus, que comprende textos sobre la India, se lleva a cabo mediante metodologías de tipo cualitativo, haciendo especial hincapié en cuatro aspectos: la enunciación y la relación entre autor y lector; la presencia de un punto de vista subjetivo vs objetivo; la dimensión temporal y espacial; la explotación
de estereotipos y conocimientos compartidos. El análisis muestra que los dos subgéneros comparten algunos rasgos textuales y, a pesar del diferente valor literario, pueden contribuir a la construcción de la imagen de los destinos, desempeñando un papel signifi cativo en la promoción turística.Starting from the assumption that texts produced in the tourist sector are a form of discourse, the paper focuses

Representation of national and regional political units in a computerized world future model
No full textFor more about the East-West Center, see http://www.eastwestcenter.org/Recent, highly-publicized computerized world future models developed by Jay W. Forrester and by Donella H. Meadows and others have formed the basis for suggested policies that would require major changes in international and national legal rules. These models make no attempt, however, to incorporate the existing world legal structure.The author has rewritten one of these models, that by Forrester, to incorporate variables representing legal controls of international movement of population, natural resources, food, and pollution. Results from computer runs with this revised model suggest that a wide range of national policies on such questions as population growth, economic growth, and national resource usage may be compatible with world equilibrium.Appendices to the paper present FORTRAN computer programs for both the original model and the author's extended model
Revitalizing housing: the vital trajectories of cooperative systems
No full textIn a present time of crisis. Disruptive, turbulent and problematic (Haraway 2022), cooperative housing have re-emerged as a resilient network. These dynamic systems came to challenge prevailing narratives about housing and city production, offering alternatives through an innovative social technology. These cooperative systems become authentic collaborative and supportive cells of habitat generation, thus forming a complex assemblage of multiple entities.
This essay invites to think about the vital and cyclical nature of housing cooperatives, by observing the phenomenon as an open system capable of establishing complex relationships that transcend the built object, towards giving value to the role of self-management and self construction played by the community.
The Mutual Aid Housing Cooperatives developed in Uruguay since 1968 is an example of comprehensive and sustainable solutions to the country’s housing needs. Supported by the National Housing Law of 1968, these cooperatives have established an alternative system that integrates environmental relationships and strengthens cross-sector collaboration between the community and the State.
The concept of vitality in cooperativism, which this essay addresses, aligns with the organic and biological approaches to perception and world-building proposed by authors such as John Turner, Donella Meadows and Donna Haraway.
The present article consolidates the importance of collective ownership in these cooperatives as both a mechanism of safeguard against real estate speculation and a symbol of popular resistance. Furthermore, it underlines the relevance of community practices and active participation in the construction and management of housing as essential pillars for sustaining the vitality construction of the system.
