Le jeu et la créativité au coeur du patrimoine : étude anthropologique des processus de patrimonialisation de la cerise à Itxassou (Pays basque) et à Sefrou (Maroc) / Playing and creativity at the heart of heritage : anthropological study of cherry heritagization processes in Itxassou (Basque country) and Sefrou (Morocco)

Briand, Anne-Laure 11 December 2018 (has links)
Au cœur des terrains d’Itxassou (Pays basque) et de Sefrou (Maroc), une nouvelle méthodologie de collecte de matériaux a été appliquée afin d’étudier et de comparer les processus de patrimonialisation à l’œuvre autour de la cerise et de ses corollaires dont les fêtes des cerises. Cette nouvelle approche méthodologique anthropologique a été développée depuis le concept d’aire transitionnelle du psychanalyste anglais Donald Woods Winnicott, l’un des fondements majeurs de ma profession d’ergothérapeute. La créativité et le jeu sont au centre de cette approche. Cette ethnographie clinique et transitionnelle a été déployée auprès d’enfants et d’adultes et a permis d’augmenter la collecte d’objets sur les terrains. Egalement, la théorie de la transitionnalité de Winnicott a aidé à distinguer différents états du patrimoine : l’objet, le patrimoine intime, le patrimoine collectif, le patrimoine et le patrimoine total. Cette théorie conjuguée à la théorie des systèmes et dans le sillage de l’anthropologue américain Gregory Bateson a permis l’élaboration d’un schéma de systémique patrimoniale. La créativité est à la fois l’énergie du sous-schéma de la transitionnalité et à la fois, l’énergie du schéma de la systémique patrimoniale. Par ailleurs, j'ai étudié les principaux blocages aux processus de patrimonialisation -les double bind- en mobilisant ensemble les travaux de quatre chercheurs pluridisciplinaires : Winnicott, Simmel, Bateson et Watzlawick. Trois double bind et leurs stratégies de dépassements issus des terrains ont ainsi été analysés. Bien que les sorties de double bind dépendent de chaque système, la similitude réside dans l'utilisation obligatoire de la créativité. / At the heart of the fields of Itxassou in the Basque country and Sefrou in Morocco, a new methodology to collect materials has been applied in order to study and compare the heritagization processes working in around cherries and the related events like cherry festivals. This new anthropological approach has been developed using the concept of transitional area due to the English psychoanalyst Donald D. Woods Winnicott, which is a fundamental concept of occupational therapy. Creativity and playing are at the core of this approach that we call clinical and transitional ethnography. It has been tested among children and adults and has allowed us to significantly improve the number of objects obtained during the field data collection. The transitional theory of Winnicott leaded us to distinguish and define different form of heritage : the object, the personal heritage, the collective heritage, the heritage and finally the total heritage. In the wake of the American anthropologist Gregory Bateson, the transitional theory together with systems theory allow us to define a systemic heritage scheme. Creativity is both the energy of the transitional sub-scheme and those of the systemic heritage scheme. We have also studied the main obstructions to the heritagization process, the so-called double bind, using previous works of four multidisciplinary researchers : Winnicott, Simmel, Bateson and Watzlawick. In particular, three double bind are defined and their exceeding strategies coming from the fields under investigation are analyzed. Although the outcomes of the double bind depends on each system, similarities can be found in the mandatory use of creativity.

L'hybridation dans l'oeuvre de Jeannette Winterson / Hybridization in Jeanette Winterson's works

Mihajlovska, Lupka 16 November 2012 (has links)
Nous définissons l’hybridation littéraire comme la combinaison d’éléments a priori disparates aboutissant à la création d’un ensemble à la fois un et multiple, qui garde les traces de ses parties constitutives tout en étant autre, différent, nouveau. L’hybride englobe les sphères de représentation de ses éléments-parents tout en les dépassant. Par conséquent, l’hybridation tend vers l’extension de toutes les frontières, littéraires et culturelles, dans le but de nous offrir une vision du monde et du sujet toujours plus complète. Dans Oranges are not the Only Fruit, Sexing the Cherry, Written on the Body et The PowerBook de Jeanette Winterson, l’hybridation se manifeste à tous les niveaux du texte. L’hybridité physique et sexuelle des narrateurs est ainsi une des manifestations de leurs identités et vies plurielles et paradoxales. Ces hybrides incarnés (monstres, travestis ou androgynes) se construisant au fil de leurs histoires, qui s’inspirent toujours de récits antérieurs, narrateurs et narrations se démultiplient conjointement, s’entremêlent et se redéfinissent sans cesse. Le texte fluctue au gré de l’hybridation générique et de l’intertextualité. De l’entrecroisement de genres réalistes – tels que l’autobiographie, le récit historique ou le discours scientifique – et fictionnels – tels que le conte ou la romance – naît un hybride générique à résonances parodiques représentant la nature du sujet, de sa vie, de la réalité et de la vérité. Enfin, en hybridant des textes préexistants à des motifs personnels, l’auteur élabore une narration originale qui réécrit les schémas sexistes relayés par ses ancêtres et retranscrit sa vision de l’individu, du monde et de l’art. / We understand literary hybridization as the combination of seemingly different elements resulting in the creation of an entity that is simultaneously single and multiple. Indeed, while it is utterly other and new, the hybrid still shows the marks of its constituents. The hybrid incorporates its ‘parents’’ initial fields of representation while reaching beyond them. Consequently, hybridization is a process that pushes all boundaries, be they literary or cultural, to offer an ever more complete vision of the subject and his/her life. In Jeanette Winterson’s Oranges are not the Only Fruit, Sexing the Cherry, Written on the Body and The PowerBook, hybridization permeates every level of the text. Thus, the narrators’ physical and sexual hybridity is a manifestation of their plural and paradoxical identities. These hybrid creatures (monsters, transvestites or androgynous beings) build their identities through the stories they tell and that are always inspired by existing narratives. Therefore, the narrators and their narratives proliferate conjointly, intermix and redefine each other constantly. The shape of the text fluctuates with generic hybridization and intertextuality. Realistic narratives – such as autobiographical, historical or scientific discourses – and fictional ones – such as fairy tales or romances – interact to produce generic hybrids with parodic undertones that represent the nature of the subject, his/her life, reality and truth. Finally, by hybridizing existing texts and personal literary devices, the author elaborates original narratives that rewrite her ancestors’ sexist discourses and reflect how she perceives the individual, the world and art.

Klimawandel und Sauerkirschanbau

Matzneller, Philipp 19 January 2016 (has links)
In dieser Arbeit wurden die Veränderungen der agrarklimatologischen Bedingungen im Zuge des Klimawandels für ausgesuchte Sauerkirschanbauregionen in Europa und Nordamerika untersucht. Es wird auf veränderte Risiken (Spätfrost, Hitzewellen, Wassermangel) hingewiesen, die durch nachhaltige, praxisorientierte und ökonomisch vertretbare Anpassungsmaßnahmen (Überdachung, Frostschutz, Bewässerung, Anbausystem, Wahl der Sorte und Unterlage, etc.) begrenzt werden können. Der Klimawandel kann neben Risiken aber auch Chancen für den Sauerkirschanbau eröffnen. Höhere Temperaturen und eine längere Vegetationsperiode können regional differenziert zu günstigeren Anbaubedingungen führen. Ein besonderer Schwerpunkt wurde auf die Entwicklung phänologischer Modelle gelegt, mit denen Veränderungen im Entwicklungsrhythmus der Sauerkirschgehölze analysiert werden konnten. Dafür wurden acht Modelle zur Vorhersage des Blühbeginns und Blühendes entwickelt. Weitere phänologische Stadien konnten mit dem Modell von Zavalloni et al. (2006) berechnet werden. Die Untersuchungen haben ergeben, dass sich der Blühbeginn unter geänderten Klimabedingungen verfrüht, aber nur geringe Verkürzungen der Zeiträume zwischen den phänologischen Stadien zu erwarten sind. Zu den gefürchteten Witterungsschäden im Obstbau gehört Spätfrost, der zu hohen Ertragsverlusten führen kann. Im Zuge des Klimawandels können sich die Häufigkeit und Stärke der Fröste ändern. Die Frostwahrscheinlichkeit während der untersuchten Entwicklungsphasen von Sauerkischgehölzen könnte in diesem Jahrhundert in Rheinland-Pfalz und Eau Claire abnehmen, während sich die Verhältnisse in den anderen Anbaugebieten nur geringfügig ändern. In einem zweiten Schritt wurden die Ertragsverluste durch Frost bestimmt. Hierbei hat sich ergeben, dass die Frostschäden in den untersuchten Anbauregionen wahrscheinlich geringer werden. Allerdings differieren die Ergebnisse zwischen den Berechnungen mit beobachteten und modellierten Temperaturen oft stark. / This thesis investigates the changes in agro-climatic conditions for selected growing region in Europe and North America under current and future climate conditions. The overall aim of the study was to identify possible risks (spring frosts, heat waves, water shortages), which can be limited by sustainable, practically oriented and economically viable adaptation measures (hail- and frost-protection, irrigation, cultivation system, choice of variety and rootstock). Besides risks, climate change can provide new opportunities. Higher temperature levels and extended growing season lengths could regionally differentiated improve the growing conditions. Particular focus was given to developing phenological models, used to investigate shifts in spring phenology of sour cherry trees due to climate change. Therefore, eight models to predict the beginning and end of blossom were optimized and validated. Further phenological stages were calculated with the model by Zavalloni et al. (2006). The results show an earlier onset in the beginning of sour cherry blossom under future climate conditions, while the length of the period between the phenological stages only shortens slightly. Spring frosts are feared weather hazards in orchards which can cause substantial yield losses. The changing climate conditions could influence the frequency and strength of spring frosts. In the course of this century the spring frost probability is likely to decrease in Rhineland-Palatinate and Eau Claire, while only slight changes are expected in the other growing regions. In the second step, yield losses caused by spring frost were calculated. The frost damages on sour cherries in the investigated growing regions will probably decrease. However, the yield losses calculated with observed and modeled temperatures often differ strongly.

Avaliação dos fatores de risco no processamento de café verde para o aparecimento de ocratoxina A (OTA) / Evaluation of risk factors in green coffee processing for ochratoxin A (OTA)

Nogueira, Márcia Dimov 03 April 2007 (has links)
Dentre os perigos relacionados com a produção de café verde, a ocratoxina A (OTA) é considerada significativa nesse produto. Com o objetivo de estudar a origem da OTA no processamento de café verde e avaliar os possíveis fatores de risco (região, etapas do processamento, fungos, insetos e ácaros) que poderiam contribuir na presença de OTA, foram amostradas três fazendas nos seguintes municípios: Bom Jardim (RJ), Espírito Santo do Pinhal (SP) e Cornélio Procópio (PR), onde havia a produção de café verde pela via seca e úmida. Foram coletadas 109 amostras de grãos de café, em diversas etapas do processamento, no período de maio a agosto de 2002. As amostras foram colhidas de acordo com fluxograma estabelecido e as etapas estudadas foram: cereja (campo), via seca, via úmida, armazém e café de varrição. Dessas amostras, 10 apresentaram OTA, que variou na sua quantificação de 3 a 101 ng.g-1. A maior prevalência de OTA foi a do café de varrição 57%, a via úmida apresentou uma prevalência de 10,3% e a via seca 7%. Na etapa cereja o fungo potencialmente toxigênico mais encontrado foi Penicillium spp, e quanto aos insetos, as larvas de Diptera e os Homoptera; na via úmida foram encontradas linhagens do Aspergillus seção Nigri e Circundatti e Penicillium spp, a infestação predominante foi a broca do café e os ácaros da família Acaridae; na etapa via seca registrou-se o isolamento de fungos do gênero Penicillium spp e Aspergillus seção Nigri , a broca do café foi a infestação predominante junto com os ácaros da família Acaridae, na etapa de armazém foram isolados Penicillium spp e Aspergillus seção Nigri, o inseto predominante foi a broca do café e os ácaros da família Acaridae; no café de varrição foram isolados Penicillium spp e Aspergillus seção Nigri e a broca do café estava presente junto com insetos da Ordem Diptera. Os resultados de cada etapa foram comparados por Análise de Variância em um nível de significância de 95%. Na análise de fatores de risco o café de varrição foi o mais significativo (p< 0,001). / The ochratoxin A (OTA) is considered to be among the most significant coffee contaminants with related hazards. With the purpose to study the origin of the OTA in the processing of green coffee and to evaluate the possible risk factors (region, step of processing, fungi, insects and mites) that could contribute in the OTA presence, had been selected three regions (states) of Brazil: Bom Jardim/RJ, Espírito Santo do Pinhal/SP and Cornélio Procópio/PR. A total of 109 samples of coffee beans were collected in conformity with flow chart established at different stages of ripening and processing: cherry (field), dry method, wet method, and warehouse and varrição coffee, from May to August of 2002. Of these samples 10 had presented OTA, which varied in its quantification from 3 to 101 ng.g-1. The biggest prevalence of OTA was the varrição coffee 57%, the wet method presented a prevalence of 10,3% and dry way 7%. In the stage cherry fungi potentially toxigenic was more found Penicillium spp, the insects had been the larvae of Diptera and the Homoptera; in the wet way it was found Aspergillus section Nigri and Circundatti and Penicillium spp, the predominant infestation was the coffee berry borer and the mite of the Acaridae family; in the stage wet methods spp was registered the isolation the Penicillium spp and Aspergillus section Nigri, the predominant infestation was the coffee berry borer together with the mites of the Acaridae family; in the stage of warehouse had been isolated Penicillium spp and Aspergillus section Nigri, and the predominant insect was the coffee berry borer and mites of the family Acaridae; in the varrição coffee had been isolated Penicillium spp and Aspergillus section Nigri the coffee berry borer was the most present insects together of Diptera. The results of each step had been with compared by Analysis of Variance. In the analysis of risk factors the varrição coffee\" was the factor most strongly related to the risk of the presence of OTA (p<0,001 ).

The role of midfield islets in pest control

Sigfridsson, Sabine January 2013 (has links)
During last century rising populations and changed market preferences have led to large structuralchanges in agriculture in the developed world. Most conventional cultivation methods involve theproduction of few monoculture crops within a homogenous landscape, where pesticides and inorganicfertilizers are used to increase yields. The cereal aphid Rhopalosiphum padi (L.) is a pest in cerealsresulting in large economic losses for farmers throughout Europe, and are currently removed withchemical pest control. However, the pesticides also affect existing ecosystem services like potentiallypest-controlling insects as well as the surrounding environment negatively. According to previousstudies higher landscape diversity leads to a higher diversity of natural enemies to pest insects, but nostudy has investigated if the pest control is enhanced around non-crop remnants such as midfield islets(MI). This thesis investigates (i) if MI will reduce the number of aphids in crop field, (ii) if larger MIwill be more effective than smaller MI by having higher aphid predation rate, and (iii) if larger MI willprovide a more effective reduction of pest insects over a longer distance from edge. To assess thepotential for pest control, aphids were glued on papers and placed at ground level in crop fields andaround MI in nine fields. The collected data was processed statistically, and the result demonstratesthat MI play an important role by providing habitats for natural enemies to pests. The increased size ofMI have a positive effect of number of aphids consumed around MI, however the distance from edgewas not significance. This study highlights the value of MI in crop fields as an existing ecosystemservice in biological pest control. The naturally occurring predators are able to reduce R.padi andthereby minimize the need for insecticide applications. / Ökat befolkningstryck och större efterfrågan av jordbruksprodukter på marknaden har det senasteseklet lett till stora förändringar i västvärldens jordbrukslandskap. Odlingslandskapet är idaghomogent och monokulturellt där besprutningsmedel används för att ge större avkastning iproduktionen. Skadeinsekten havrebladlus (Rhopalosiphum padi) angriper vårgrödor vilket leder tillstora ekonomiska förluster för bönder runtom i Europa. Pesticider används för att reducera angreppenmen påverkar även miljön negativt samt existerande ekosystemtjänster, såsom naturliga fiender sombiologiskt kan begränsa skadeinsekters angrepp. Tidigare studier visar att heterogena landskap har enhög biologisk mångfald, men ingen studie har undersökt åkerholmars (ÅH) eventuella potential förbiologisk bekämpning av skadeinsekter i säd. Denna studie undersöker därför (i) om ÅH leder tillökad reducering av havrebladlöss i säd, (ii) om större ÅH är mer effektiva än mindre i frågan ompestreducering, samt (iii) om större ÅH begränsar lusangrepp längre ut i fält från ÅH:s kant än mindreholmar. Studiens hypoteser testades genom experiment utförda i nio fält med vårgrödor där lössklistrades på etiketter som placerades ut i omgivande fält. Dessa samlades in efter tjugo fyra timmarför att studera antal löss konsumerade i relation till ÅH. Det insamlade materialet är bearbetatstatistiskt och resultatet visar att ÅH spelar en betydande ekologisk roll för naturliga fiender tillskadeinsekten havrebladlus. Fler löss konsumerades runt större ÅH än de med mindre yta eller i de fältutan ÅH. Däremot har avståndet från ÅH en mindre betydelse, vilket indikerar att pestreduceringen ärmest effektiv nära stora ÅH. Denna studie synliggör värdet av existerande ÅH som inhysernyttoinsekter i jordbrukslandskapet, samt att heterogena landskap har högre potential för en mernaturlig skadedjursbekämpning. Naturliga fiender är därmed en existerande ekosystemtjänst som kanbegränsa bladlusangreppen (R.padi), som i sin tur ger möjligheten att reducera användandet avbekämpningsmedel, vilket för oss närmare miljömålet ”en giftfri miljö”.

Collaboration for Environmental Sustainability on Gotland, Sweden. Nature’s Blueprint: Biomimicry as a Potential Strategy.

Le, Thao January 2023 (has links)
This master's thesis explores the potential for collaboration among diverse actors on the island of Gotland to achieve environmental sustainability. The study employs the concept of biomimicry, utilising selected natural phenomena as a source of inspiration. A theoretical framework and qualitative research methodology are employed to guide the process, with the aim of developing a strategy to enhance the collaborative state for environmental sustainability on Gotland. Drawing on principles derived from nature, the study investigates how biomimicry can provide solutions and inspire collaborative efforts for environmental sustainability. Central to the research is the exploration of trust-building mechanisms among diverse actors. Recognising that trust is a fundamental ingredient for effective collaboration, the study examines strategies that can foster trust within the context of environmental sustainability. By identifying barriers and enablers of trust, the thesis proposes actionable recommendations to enhance the trust-building process on Gotland, thereby fostering a conducive environment for collaboration. The proposed strategy aims to create a collaborative framework that fosters long-term partnerships, harnessing the diverse expertise and resources of each actor to address the multifaceted challenges of environmental sustainability on Gotland. In conclusion, this master's thesis underscores the value of applying biomimicry principles to foster collaboration for environmental sustainability on Gotland.
