Abstract:

The purpose of this review was to investigate in scientific literature what impact clinical supervision actually contains from the perspective of the working conditions for nursingstaff. Goodman formed the working process in our review and is based on a systematic scrutiny and analysis of ten scientific articles inspired of evidencebased method. Willman & Stoltz and Pearson's FAME scale was used sifting through evidence of the articles.The result has been divided thematic in professional development, personal development, development of knowledge, communicationskills, feeling of fellowship, working environment and the patientinteraction. The conclusion of the evidens grading (A-D), in the quantitative results, showed no evidens (D). The qualitative articles was graded (1-5) through the concepts Feasibility, Appropriatness, Meaningfulness and Effectiveness. The result from the qualitative evidens grading was positive. None of the articles scored less than 3. In reference to Appropriateness and Meaningfulness all the studies scored maximum. The result shows that clinical supervision has got several positive impacts on the working situation for nursing staff. Syftet med denna systematiska litteraturstudie var att i vetenskaplig litteratur utifrån vårdpersonals perspektiv undersöka vilken påverkan omvårdnadshandledning har för vårdpersonals arbetssituation. Goodman låg till grund för arbetsprocessen i examensarbetet. Metoden baserades på systematisk granskning och analys av tio vetenskapliga artiklar inspirerad av evidensbaserad metod. Resultatet delades in tematiskt efter påverkan på vårdpersonals yrkesutveckling, -personlig utveckling, -kunskap, -kommunikationsförmåga, -känsla av gemenskap, -arbetsmiljö och -patientkontakt. Vid evidensgraderingen utgick de kvantitativa artiklarna ifrån Willman & Stoltz och de kvalitativa artiklarna utgick från Pearsons FAME-skala. Slutsatsen av evidensgraderingen A-D, resulterade i ingen evidens (D) för de kvantitativa resultaten. De kvalitativa artiklarna graderades från 1-5 utifrån koncepten Genomförbarhet, Lämplighet, Mening och Effektivitet. Resultatet av den kvalitativa evidensgraderingen var positivt, ingen av studierna fick sämre poäng än 3. Avseende Lämplighet och Mening fick alla studier högst poäng. Resultatet av denna systematiska litteraturstudie visar att handledning av vårdpersonal ger positiv påverkan på vårdpersonals arbetssituation.

Abstract:

Oasen i arbetsplatsen är ett designförslag på hur en restorativ zon i våra arbetsmiljöer skulle kunna gestaltas. Oasen är en tillgänglig plats för daglig återhämtning. En källa som är kravlös, stimulerar och omhändertar våra sinnen. Många i arbete väntar på att de ska känna sig trötta innan de tar paus, men det behöver inte betyda att hjärnan inte är trött. Att utveckla en plats för återhämtning leder till mer genomtänkta beslut och mer energi i vårt dagliga arbete. I förslaget har tre produkter utvecklats: en pedestal för växter, en gungsoffa och skärmvägg. Idag finns det få etablerade zoner för återhämtning i våra arbetsplatser. Forskning visar att det effektivaste sättet att återhämta sig i arbete är inte sömn utan s.k. vaken vila. Vaken vila kan vara när vi låter blicken vila på något utan koppling till prestation. I den vakna vilan rensas och bearbetas undertryckta tankar, vilket vi får ny mental energi. Den miljö människan återhämtar sig som allra bäst är i naturen. Vi har lättare för återhämtning i naturen eftersom den innehåller många element vi upplever som positiva: det handlar om att naturen ställer färre krav på oss människor, vi blir fascinerade, naturen har en vidd och en läsbarhet vilket vi finner trygghet i. Inom landskapsarkitekturen finns en forskningsgren i miljöpsykologi där naturintryckens restorativa påverkan på människan studeras för att kunna utveckla ex, rehabiliteringsträdgårdar. Restorativa naturintyck i vår interiör är fortfarande ett oexploaterat område inom designforskning. Idag har vi börjat inse värdet av sådan typ av forskning, eftersom vår innemiljö betyder mycket för vårt välbefinnande. Ännu finns ingen metod för att kunna säkerställa och kvalificera den typ av restorativa effekter en sådan interiör skulle kunna ge. Därför kommer detta arbete fungera som ett bidrag till den diskussionen. I arbetet har jag tittat framförallt på tre forskare inom restorativa naturteorier: Rachel och Stephen Kaplan samt Roger S. Ulrich. I min undersökning har jag även frågat människor om deras tankar kring produkter och miljöer. I slutet av undersökningen finns en intervju med Madeleine Stjärne, inredningsarkitekt på Sweco. Hon arbetar med ett forskningsprojekt tillsammans med SLU som handlar om ”restorativa naturintryck i interiörer”. I slutet på rapporten har jag även tagit fram ett designförslag på en restorativzon i arbetsplatsen.

Abstract:

Olika kontorstrender kommer och går och den flexibla arbetsplatsen har blivit allt vanligare i samhället. Idén om att varje individ själv ska ha möjlighet att välja sin arbetsplats efter olika arbetsuppgifter är grundtanken i det aktivitetsbaserade arbetssättet, en kontrast till de klassiska cellkontoren. Konceptet aktivitetsbaserade flexkontor bygger på att arbetsmiljön utformas i olika zoner efter verksamhetens olika aktiviteter, men tidigare forskning visar på att kontorsformen inte alltid används som den är tänkt eller att arbetsmiljön inte stödjer de behov som finns hos medarbetarna. Den här studien handlar om att undersöka de lugna zonerna i ett aktivitetsbaserat flexkontor. Studien är i samarbete med Försäkringskassans huvudkontor i Stockholm som sedan 2016 arbetat aktivitetsbaserat, men där de anställda idag ofta väljer att sitta på samma plats varje dag. Det har resulterarat i att lugna zonerna idag inte används i någon större utsträckning. Syftet med studien är att undersöka vilka rumsliga behov som användare av ett aktivitetsbaserat flexkontor har i en lugn zon och hur en lugn zon kan kommunicerar dess användande och funktioner. Intervjuer, frågeformulär och rumsanalys har tillämpats för att få en djupare förståelse om problematiken och för att besvara frågeställningarna för denna studie. Tillsammans litteraturstudier om visuell retorik, visuella element i rummet, zonindelning samt deltagande och inkluderande design så presenteras ett gestaltningsförslag på hur ett rums funktioner kan kommuniceras genom visuella element som form, färg och material och en utformning av en lugn zon som stödjer användares behov.

Abstract:

In Sweden over 60 % of the population live in a city with a population over 5000 inhabitants (Statistiska centralbyrån). The city life is in many ways considered to be a more sustainable lifestyle with shorter transportation routes and possibilities to co-use various systems. The life in the city consists (like anywhere) of eating food, drinking beverages, usage of hygiene products and clothes, usage of energy for laptops, phones and lights, transportation to work, schools and various appointments. Together all of it somehow fulfil our basic needs. These basic needs are generally not supplied by the cities we live in. We depend on the hinterlands either within Sweden or outside of Sweden. The hinterlands consist of all sorts of resources from water to fertile soil to minerals. Today and through history these resources and the value of them are put into the cities. Often done so at the cost of the environment and the people living there. At the cost of the environment and people, the lack of providing resources for the nation in general and cities in particular is the reason this thesis focus on "How could we review what a sustainable lifestyle is and instead create a more metabolic system between cities and the hinterland?". The question is studied within the setting of the island Oaxen and througout the thesis the author explores different perspectives and themes of it.

Abstract:

I denna design placeras skogsgläntan ut i stadsmiljö genom en naturridå och skapar en plats med ett rekreativt och rofyllt erbjudande. I likhet med en oas förmedlar gläntans kontrasterande upplevelse i en effektivt utformad omgivning med ständig puls en sinnlig stund av vila, trygghet eller samtal med andra som stannat upp. Gestaltningen är inspirerad av ett antal fascinerande naturupplevelser som formmässigt landade i en alternativ lummighet med vinterskrud. Gestaltningens inspiration och utformningen med växtmaterial uppmuntrar tillsammans till gemenskap med det vackra i naturen och även till gemenskap med andra, i utomhusmiljö. Både växtlighet och gemenskap har påvisade goda effekter för våra välmåenden, som utan att ofta prioriteras eller kalkyleras har ovärderlig betydelse för enskilda individer såväl som för ett större samhällsperspektiv. Kanske finns något att lära från naturens opåskyndeliga tillväxt som formar de mest fascinerande organiska och lugnande former när vi möter strikta och effektiva stadsrum. Stanna upp en stund och lägg märke till något som växer. I en speciell tid blir det särskilt viktigt att fylla sitt sinne med det som uppmuntrar, att se det vackra, att se andra såväl som att själv få bli sedd. Designförslaget är ett erbjudande om precis detta. In this design, the forest glade is placed in an urban environment in the form of a nature drop scene which is creating a recreational and peaceful contribution. Like an oasis, the contrasting experience of the forest glade in an efficiently designed environment with a constant pulse conveys an eloquent moment of rest, comfort or conversation with others who have paused. The design is inspired by a number of fascinating nature experiences that introduced an alternative lush form with winter vesture. Together, the inspiration of the design and the plant formations encourage fellowship with the beautiful in nature and also fellowship with others, in an outdoor environment. Both vegetation and fellowship have beneficial effects on our well-being, which without often being prioritized or calculated has invaluable significance for individuals as well as for a larger societal perspective. Perhaps there is something to be learned from nature's unhastenable growth that shapes the most fascinating organic and calming forms when we encounter strict and efficient urban spaces. Stop for a moment and notice something growing. In an extraordinary time, it becomes especially important to fill the mind with what encourages, to see the beautiful, to see others as well as to be seen. This is what the design is proposing.

Abstract:

Agro-biodiversity in the desert oases of Baja California, Mexico is a product of isolation and integration through time and across the various spaces of the peninsula. The oases hold heirloom perennial crop species first introduced by Jesuit missionaries (1697-1768) and represent geographies of historical dissemination. I selected fifteen Jesuit mission oases and surveyed the oasis gardens for species richness and abundance. To understand the cultural, political and economic forces that create these patterns of persistence within the oases, I conducted interviews on farming system practices, geographical remoteness, market integration, land tenure, tourism, protected area status and cultural practices. In all, I surveyed 241 gardens and documented eighty-nine total perennial crop species. Historical records in 1774 describe twenty-one perennial crop species in cultivation after the Jesuit expulsion. I calculated species-area relationships and rank-abundance for total perennial and mission crop species in each oasis and inventory comparisons for those oases with quantitative historical data to analyze retention of historic mission species. A high persistence of mission species indicates that oases serve as agro-biodiversity refugia, or protected source areas for agricultural species. These mission-oases act as a network of interconnected sites that are also isolated from one another and the Mexican mainland by the rugged environment, limited transportation infrastructure, and by sea. Within the network, these fifteen oases span a range of small and hours distant from the nearest resource center, to fully urbanized with international ports and airports. I describe how phases and processes of isolation and connectivity shape and transform the agro-biodiversity profiles in this archipelago of peninsula oases.

Abstract:

Water has a critical role in sustaining both natural ecosystems and human livelihoods. However, nowadays intensive population growth and increasing pressure on natural resources lead to substantial issues related to water services provision. At the same time, mismanagement of water resources hinders water security and leads to escalation of water-related challenges. Thus, the research of principles for good water governance has got a substantial attention and aimed at establishing new policies and institutional frameworks for addressing those challenges. Pluralistic forms of governance, with the focus on community water governance has been advocated as a way to more sensibly tackle the complexity of issues linked to water systems. The present research aims to investigate the specifics of community water governance and analyze how community governance practices can contribute to a more sustainable management of water systems on the case of Oaxen island in Stockholm archipelago.

Abstract:

O silêncio e o espaço cotidiano das ações das mulheres são referenciais de análise na construção do entendimento da transmissão da memória e da identidade religiosa dos grupos de mulheres da Ordem Auxiliadora de Senhoras Evangélicas na Igreja Evangélica de Confissão Luterana no Brasil. O silêncio não fala, não é possível traduzi-lo em palavras, mas nas ações ele se torna palavra. As ações cotidianas e o testemunho de fé das mulheres da OASE, em silêncio, são indicações do formato social de nossa realidade sócio-religiosa. A tese do silêncio que sustentamos advém das palavras das próprias protagonistas da ação. Este silêncio não é sinônimo de ausência ou de fraqueza. É presença e também poder. A rede de poder é uma teia que se alastra por toda a sociedade e ninguém pode dela escapar. Também as mulheres da OASE, em seu centenário silêncio, exercem o poder. Analisar as teias do poder que são vivenciados nas relações cotidianas destas protagonistas é olhar para a particularidade da vida. A tentativa de mergulhar no cotidiano, de buscar o significante do invisível é por reconhecê-lo como espaço, tempo e lugar dos conflitos racionais e irracionais de nossa época, onde se estabelecem os problemas de produção da vida concreta. Nas redes do cotidiano, estão os nós, os laços a serem atados ou desatados. É no espaço cotidiano que se cuida das necessidades básicas da vida. A prática do cuidado é um referencial importante da ação das mulheres. Ela acontece em muitos espaços, mas é na cozinha que se concentram a maioria das suas ações, tanto no cotidiano doméstico quanto nas ações comunitárias. A cozinha é o lugar que permite o acesso ao entendimento da cultura, da expressão religiosa que definem o comportamento e a forma de como se entende a vida e a fé cotidianamente. O espaço da cozinha é o lugar da memória, dos cheiros, da continuidade das relações. É em torno da mesa que a comunhão é vivenciada. É através da memória que os valores da fé são transmitidos. Portanto, é a memória guardada pela mãe que as faz pertencer ao universo religioso de comunhão, de testemunho e de serviço. O perfil característico deste grupo tem na memória transmitida a construção do vínculo. Este também é o perfil característico da mobilização religiosa: a perpetuação da memória como construtora da continuidade religiosa. É a memória religiosa que conserva, reproduz e garante a permanência de um pensamento, de uma identidade confessional. Temos no grupo das mulheres da OASE um valorativo e comprovado potencial de guarda da memória da identidade religiosa e da continuidade da mesma. The silence and the daily space of the women actions are referentials of analysis in the understanding construction of the memory transmission and the religious identity of the groups of women of the Ordem Auxiliadora de Senhoras Evangélicas na Igreja Evangélica de Confissão Luterana no Brasil. Silence doesnt speak, its not possible to translate it in words, but in actions it becomes word. The daily actions and the Faith Testimony of the OASE women in silence are indications of the social format of our partner-religious reality. The Thesis of silence that we support happens of the words of the proper protagonists of the action. This silence is not synonymous of absence or weakness. It is presence and also to be able. The net of being able is a web that spreads over all the society and nobody can escape of it. Also the OASE women in its centenarian silence exert the power. To analyze the webs of the power that are deeply lived in the daily relations of these protagonists is to look at to the particularity of the life. The attempt to dive in the daily one, to search the significant one of the invisible one is to recognize it as space, time and place of the rational and irrationals conflicts of our time, where are establish the production problems of the concrete life. In the nets of the daily one are the ties, bows to be tied or unfastened. Its in the daily space that we take care of the basic necessities of life. The practical of the care is an important referential of the women action. It happens in many spaces but its in the kitchen that concentrates most part of the two actions, as in the daily domestic service as in the communitarian actions. The kitchen is the place that allows the access to the culture understanding, of the religious expression that defines the behavior and the form of how is understood the daily life and faith. The kitchens space is the place of memory, of smells, of relations continuity. Its around the table that the communion is deeply lived. It is through the memory that the values of Faith are transmitted. Therefore, its the memory kept by the mother that makes them belong to the religious universe of communion, testimony and service. The characteristic profile of this group has in the transmitted memory the links construction. This also is the characteristic profile of the religious mobilization: the perpetuation of the memory as constructor of the religious continuity. Its the religious memory that conserves, reproduces and guarantees the permanence of a thought, of a confessional identity. We have in the group of the OASE women a valuable and proven potential of guard of the religious identity memory and the continuity of the same.

Abstract:

The focus of the study is on restorative experiences and the relationship between these experiences and psychological well-being. The variety of experiences that people experience as restorative were explored, as well as how often these experiences occurred. A working definition were written since no generally accepted definition of restorative experiences exists. A checklist with 22 categories of restorative experiences has also been drawn up. Students completed psychological well-being questionnaires and the results were used to form two groups: one with higher and one with lower levels of psychological well-being. The two groups were compared in terms of the restorative experiences present in their lives. Nature emerged as the most popular restorative environment. Rest was the most popular category with subcategories for sleep and holidays. Interpersonal contact was also a popular category for both groups. The categories for eating and drinking and activities that are damaging to the body showed important differences between groups in terms of popularity and frequency. The group with the higher levels of psychological well-being shows signs of a healthier lifestyle and they have a greater capacity to postpone gratification. In addition, they show fewer signs of substance dependency, fewer symptoms of psychological disorders and less avoidance than the group with the lower levels of psychological well-being.

Vatten är avgörande för allt liv på jorden och utgör FN:s sjätte globala hållbarhetsmål ”rent vatten och sanitet”. Denna rapport syftar på att undersöka vattenbesparing inom hushåll genom en fallstudie av Oaxen och Sandön med tillhörande kommuner Södertälje och Värmdö. Genom litteraturstudier kartlades befintliga vattenbesparingsåtgärder och kommunernas vattenarbete undersöktes både genom litteraturstudier samt intervjuer. En enkätstudie genomfördes även för att kartlägga individers beteende, kunskap och inställning till vattenbesparingsåtgärder. Det erhållna resultatet från enkätstudien visade på en positiv inställning till vattenbesparingsåtgärder och många individer har en stor medvetenhet kring sitt beteende relaterat till vattenanvändning. Litteraturstudien och intervjuerna visade vidare att det i dagsläget finns få riktlinjer relaterat till vattenbesparing och befintliga riktlinjer fokuserar framförallt på ramar för vattenanvändning snarare än att införa rekommendationer kring olika vattenbesparingsåtgärder. Slutligen rekommenderas snålspolande munstycken (sparstrålsamlare) och snålspolande toaletter som de bästa åtgärderna baserat på vattenbesparing, installationskostnad, kostnadsbesparing och individers inställning. Water is crucial for all life on earth and constitutes UN’s sixth sustainable development goal ”Clean Water and Sanitation”. This report aims to study water conservation in households through a case study of the two islands Oaxen and Sandön with their associated municipalities Södertälje and Värmdö. Existing water conservation measures were identified through literature studies and the municipalities efforts in water management were studied through both literature studies and interviews. A survey was also conducted to study individuals’ behaviour, knowledge and view on water conservation measures. The result obtained from the survey study showed a positive view to water conservation measures and many respondents showed great awareness regarding their behaviour related to water usage. Furthermore, the literature study and the interviews convey that there currently are few guidelines related to water conservation. Existing guidelines mainly focuses on limitations for water usage rather than introducing recommendations on different technical water conservation measures. In conclusion, low-flush nozzles and toilets are recommended since they are considered to be the best water conservation measures based on installation cost, cost savings, water conservation and individuals’ views. Recirculating shower and usage of rainwater are to be considered for those having the possibility to make a bigger investment due to the water conservation being great.

Abstract:

Les oasis de la vallée du M’Zab en Algérie, inscrites au patrimoine mondial de l’humanité, présentent une architecture et une morphologie urbaine exceptionnelles. Elles ont légitimement attiré depuis longtemps aussi bien l’attention des voyageurs, que celle des chercheurs et des aménageurs. Une particularité reste cependant largement méconnue : le mode de vie et l’habitat des Mozabites, qui se sont constitués en fonction des variations saisonnières. Aujourd’hui, l’opposition systématique entre la taddart dans les ksour et le akham dans les palmeraies est remise en cause par une urbanisation accélérée, une poussée démographique et un effacement progressif du rythme des saisons dans les déplacements domestiques et urbains. Si aujourd’hui la désignation des deux types d’habitat est toujours d’actualité, qu’en est-il de leurs caractéristiques formelles et de leurs modes d’habiter ? Ce travail se propose d’étudier l’évolution des inscriptions tant physiques que sociales de ces variations saisonnières dans les types d’habitat et la forme urbaine de l’oasis de Beni Isguen, l’une des cinq oasis de la pentapole de la vallée du M’Zab The M'Zab Valley oases in Algeria, listed as World Heritage has an exceptional architecture and urban morphology. It has caught legitimately and for a long time the travelers’ attention, as well as researchers and urban planners. However, a special feature remains largely unknown: the role of seasonal variations in the Mozabites way of life and habitat. Nowadays, the accelerated urbanization, the population growth and the gradual erosion of the seasonal rhythm in the domestic and urban movements challenge the systematic opposition between the taddart – the winter habitat of the ksour – and the akham – the summer habitat of the palm groves. This research aims to study the evolution of the physical and social inscriptions of these seasonal variations in the habitat types and the urban morphology of the Béni Isguen oasis, one of the five oases of the M’Zab Valley pentapolis

Abstract:

Im Rahmen einer deutsch-australischen Forschungskooperation erfolgte im Südsommer 2001/2002 eine Expedition in die Amery-Oase (70°50’S, 68°00’E), die im Einzugsgebiet des Lambert-Gletscher/Amery-Schelfeis-Systems, dem größten ostantarktischen Eis-Drainagesystem, liegt. Von deutscher Seite wurden im Zuge der Geländekampagne erstmals lakustrine Sedimentsequenzen gewonnen, um die bislang wenig erforschte spätquartäre Klima- und Umweltgeschichte dieser rund 1800 km2 großen eisfreien Region zu rekonstruieren. Die drei untersuchten Glazialseen Beaver, Radok und Terrasovoje unterscheiden sich sowohl deutlich in ihrer Größe, Bathymetrie und den hydrologischen Merkmalen sowie in ihren Sedimentabfolgen. Einen Schwerpunkte dieser Doktorarbeit bildet die Rekonstruktion der Sedimentationsprozesse und des Ablagerungsmilieus sowie Untersuchungen zur Herkunft des detritischen Sedimentmaterials in den Seebecken. Der methodische Ansatz verfolgt die Charakterisierung der klastischen Sedimentfazies an Hand lithologisch-granulometrischer Merkmale sowie mineralogisch-geochemischer Analysen der Sedimentherkunft. Ein weiterer Schwerpunkt ist die Rekonstruktion der holozänen biogen gesteuerten Ablagerungsbedingungen im Terrasovoje-See, die Rückschlüsse auf den kurzfristigen postglazialen Klima- und Umweltwandel in der Amery-Oase gestattet. Dabei wurden mikrofazielle Untersuchungsmethoden und hochauflösende Elementscannermessungen angewandt. Die klastische Sedimentherkunft in den drei Seen unterscheidet sich räumlich deutlich voneinander und spiegelt den komplexen geologischen Aufbau der Amery-Oase wider. Als Sedimentquellen konnten präkambrische Metamorphite, permotriassische Sedimentgesteine und tertiäre Lockersedimente identifiziert werden. Die Varibilität der Herkunftssignale ist zeitlich weniger deutlich als räumlich ausgeprägt und deutet auf relativ konstante Liefergebiete in den einzelnen Seen hin. Das glaziolakustrine Ablagerungsmilieu der drei untersuchten Seen zeigt klare räumliche und zeitliche Unterschiede. In allen drei Seen setzen sich die älteren Sedimente aus grobkörnigem, häufig diamiktischem Material zusammen, während die jüngeren Sedimente aus feinkörnigen Laminiten bestehen. Die lithofazielle Zweiteilung in den Sedimentabfolgen deutet auf einen Rückzug der Gletscher und/oder einen Anstieg der Wassertiefen im Übergang von den grobkörnigen zu den feinkörnigen Ablagerungseinheiten hin. Die oberen feinkörnigen Kernabschnitte spiegeln in allen drei Seen die postglaziale lakustrine Sedimentation wider. Im Beaver-See wird die postglaziale Fazies durch laminierte klastische Stillwassersedimente repräsentiert, im Radok-See durch Turbiditsequenzen und im Terrasovoje-See durch Algenlaminite. Abgesehen vom Terrasovoje-See ist die zeitliche Einordnung der Fazieswechsel auf Grund mangelnder Altersinformationen schwer erfassbar. Im Terrasovoje-See setzte die postglaziale Sedimentation um rund 12,4 cal. ka ein. Somit weisen die darunterliegenden glazigenen Klastika mindestens ein spätpleistozänes Alter auf. Die sedimentologischen Eigenschaften, Änderungen der Sedimentationsraten und organogene Zusammensetzung der postglazialen Biogenlaminite des Terrasovoje-Sees deuten auf Variationen der paläolimnologischen Bedingungen hinsichtlich Eisbedeckung, biologischer Produktivität, Wasserstand, Redoxbedingungen und Salinität hin, die mit regionalen holozänen Klimaänderungen in Verbindung gebracht werden können. Weitere Anhaltspunkte ergeben sich aus der Zusammensetzung und den Mächtigkeitsvariationen der Laminae, die generell aus Wechsellagerungen von Cyanobakterienmatten mit feinklastischen Lagen bestehen. Lagenzählungen der Laminae belegen Änderungen des Ablagerungsmilieus auf subdekadischen Zeitskalen, wobei zeitweilige jährliche Signale nicht ausgeschlossen werden können. Unter Berücksichtigung aller faziellen Indikatoren lässt sich aus der Sedimentabfolge des Terrasovoje-Sees ein frühholozänes Klimaoptimum zwischen 9 und 7 cal. ka sowie weitere Wärmephasen zwischen 3,2 und 2,3 cal. ka sowie 1,5 und 1,0 cal. ka ableiten. Im Vergleich mit Eiskernarchiven und anderen Seesedimentabfolgen aus ostantarktischen Oasen zeigt sich, dass das Auftreten postglazialer Warmphasen nicht allenorts einem allgemein gültigen räumlich-zeitlichen Muster folgt. Die Ursachen hierfür liegen vermutlich in den lokalen geographischen Gegebenheiten. Es lässt sich daraus schliessen, dass die bisher vorliegenden Klimarekonstruktionen eher das Lokalklima an einem Untersuchungsstandort als das Großklima der Ostantarktis reflektieren. Daraus ergibt sich die Notwendigkeit weiterer Untersuchungen von antarktischen Klimaarchiven und Untersuchungsstandorten, um örtliche von überregionalen Klimasignalen besser unterscheiden zu können. In the scope of a German-Australian research cooperation field work was conducted in the Amery Oasis (70°50’S, 68°00’E), situated in the Lambert Glacier/Amery Ice Shelf region, the largest East Antarctic ice drainage system. The German part comprised the retrieval of lacustrine sediment cores for the reconstruction of the late Quaternary development of the palaeoenvironment in the 1800 km2 large ice-free region. The three studied glacial lakes Beaver, Radok, and Terrasovoje reveal marked differences in size, hydrology and their sedimentary inventory. The goals of this thesis were to infer the onset of depostion in the lacustrine basins and to characterize changes in the depositional environment in the course of glacial retreat and the postglacial climate development. The methodic approach followed the recognition of sedimentary facies variability and sediment sources by means of facies analysis and mineralogical-geochemical provenance analysis. Another aspect was the high-resolution reconstruction of postglacial biogenic sedimentary modes in Lake Terrasovoje that provide insights into the short-term Holocene palaeo-climatic and palaeoenvironmental development. The origin of siliciclastics shows marked spatial differences between the lakes, reflecting the complex geological setting of the Amery Oasis. The main detrital sources comprise crystalline rocks of the East Antarctic craton, Permotriassic and Tertiary sedimentary rocks. The temporal variability of sediment provenance is less developed than the spatial pattern, pointing to relatively constant sediment sources through time in the respective lakes. The glaciolacustrine depositional environment of the three lakes shows clear spatial and temporal contrasts. In all lakes, the older sediments are composed of coarse, partly diamictic lithologies, while the younger materials consist of fine-grained laminites. The twofold lithofacial pattern is related to regional glacial retreat at the boundary between both sedimentary units that reduced direct glacigenic sediment input. In the epishelf Lake Beaver, in addition, the effect of postglacial sea-level rise led also to the rise of lake level and shifted the study site towards a more distal position from the shore, away from the influence of coarse clastic sediment input. The upper sedimentary units of the three lakes are dominated by fine-grained sediments, which only occasionally include ice-rafted dropstones. The postglacial sediments comprise clastic stillwater laminites at Lake Beaver, finely laminated turbidites in Lake Radok, and algal laminites in Lake Terrasovoje. Apart from Lake Terrasovoje the timing of the lithological change is hard to determine, because of missing age constraints. At Lake Terrasovoje, the postglacial sequence started at approximately 12.4 cal. ka BP, suggesting an late Pleistocene age for the underlying glacial sediments. Sedimentological features, changes in sedimentation rates, and the compositional variability of the organic-rich postglacial laminites in Lake Terrasovoje point to variations in the palaeolimnic environment in terms of ice cover, biological productivity, lake level, redox conditions, and salinity that can be related to the regional Holocene climate history. Further evidence arises from the structure, composition, and thickness variations of the laminae, which basically consist of alternations of algal mats (cyanobacteria) and fine-clastic layers. The counting of laminae couplets reveal changes in the depositional enviroment at sub-decadal time scales that partly might include annual layering. Under the consideration of all sedimentological facies indicators, the postglacial laminite sequence of Lake Terrasovoje documents an early Holocene climate optimum between 9 and 7 cal. ka as well as two warm spells between 3.2 and 2.3 cal. ka and 1.5 and 1.0 cal. ka, respectively. In comparison with ice-core records and lake records from other East Antarctic ice-free regions, it becomes evident that the appearence of warm episodes does not follow a consistent spatial-temporal pattern. Common trends comprise the existence of an early Holocene climate optimum, as seen in the ice-core records and in the Amery Oasis, and several warm episodes in the middle to late Holocene that are often time-transgressive. The cause of this inconsistent pattern probably can be explained by local boundary conditions that affect the study sites, such as topography, maritime influences and the distance to glacial ice. Therefore, many climate reconstructions basically document local climate rather than overregional Antarctic climate. In conclusion, there is need for ongoing palaeoclimatic studies in East Antarctica and the establishment of a dense network of study sites to distinguish and validate local from overregional palaeoclimatic fingerprints.

Abstract:

The Levantine Paleolithic record is central to understanding human migrations out of Africa and the relationship between Neanderthals and Anatomically Modern Homo sapiens. Lithic remains are the most plentiful source of information on these ancient peoples, and understanding how they can be used to infer cognitive abilities, mobility patterns and settlement strategies is essential to Paleolithic studies. A review of published Middle Paleolithic sites in Jordan demonstrates that currently accepted theories on Levantine Middle Paleolithic archaeology can be used as a framework only. Sites must be understood according to their specific contexts, and local Jordanian environments depend as much on tectonics and base water levels as they do on generalized climatic records. Lithic assemblages show that organizational flexibility was a key component to human adaptations and modern behavior is already present in Jordan early in the Middle Pleistocene. Les données du Levant paléolithique sont indispensables pour l'étude des migrations humaines hors de l'Afrique et pour celle des relations entre les Néanderthaliens et Homo sapiens sapiens. Les vestiges lithiques représentent la source de renseignements la plus importante au sujet de ces populations anciennes. Il est essentiel pour l'étude du Paléolithique de comprendre comment l'on peut utiliser ces renseignements afin d'en déduire les capacités cognitives, les trajectoires de mobilité et les stratégies d'établissement de ces hommes. Une révision des publications au sujet des sites du Paléolithique moyen en Jordanie démontre que les théories archéologiques courantes s'y rapportant ne peuvent constituer qu'un cadre. En effet, les sites doivent être étudiés selon le contexte particulier de chacun. Ainsi, la tectonique et le niveau de la nappe phréatique produisent des environnements locaux en Jordanie qui diffèrent des données climatiques généralisées. En outre, l'on peut démontrer à l'aide d'assemblages lithiques que la souplesse organisationnelle représentait un élément clé de l'adaptation humaine. Le comportement moderne est déjà présent en Jordanie au début du Pléistocène moyen.

Abstract:

The Nubian Aquifer System is the primary aquifer in the Western Desert of Egypt. The Dakhla Oases are among five other oases relying on this aquifer as the only source of water. The water-bearing layers are mainly porous Cretaceous sandstones overlain by predominantly marine shales and clays of Late Cretaceous to Lower Paleocene age. Ground water occurs under artesian conditions causing the wells to flow freely for both human and agricultural needs. The present annual ground-water discharge in Dakhla is 2.09 x 10⁸ cubic meters. The natural movement of ground water into the Dakhla area is negligible in terms of recharge to the artesian zones. A review of previous investigations indicated a projected drawdown of up to 75 meters by the year 2025. Extensive extraction from the deep layers has led to a decrease in the piezometric pressure, causing vertical flow from the upper layers. The decrease in natural flow of the artesian wells is due to this decline in natural pressure. Egypt is in great need of its ground-water supply. In the context of population growth and greater demands for water, the value of water in Egypt will rise in the near future particularly in response to the imminent threat of African drought.

Abstract:

Fog oases, locally named Lomas, are distributed in a fragmented way along the western coast of Chile and Peru (South America) between ~6°S and 30°S following an altitudinal gradient determined by a fog layer. This fragmentation has been attributed to the hyper aridity of the desert. However, periodically climatic events influence the ‘normal seasonality’ of this ecosystem through a higher than average water input that triggers plant responses (e.g. primary productivity and phenology). The impact of the climatic oscillation may vary according to the season (wet/dry). This thesis evaluates the potential effect of climate oscillations, such as El Niño Southern Oscillation (ENSO), through the analysis of vegetation of this ecosystem following different approaches: Chapters two and three show the analysis of fog oasis along the Peruvian and Chilean deserts. The objectives are: 1) to explain the floristic connection of fog oases analysing their taxa composition differences and the phylogenetic affinities among them, 2) to explore the climate variables related to ENSO which likely affect fog production, and the responses of Lomas vegetation (composition, productivity, distribution) to climate patterns during ENSO events. Chapters four and five describe a fog-oasis in southern Peru during the 2008-2010 period. The objectives are: 3) to describe and create a new vegetation map of the Lomas vegetation using remote sensing analysis supported by field survey data, and 4) to identify the vegetation change during the dry season. The first part of our results show that: 1) there are three significantly different groups of Lomas (Northern Peru, Southern Peru, and Chile) with a significant phylogenetic divergence among them. The species composition reveals a latitudinal gradient of plant assemblages. The species origin, growth-forms typologies, and geographic position also reinforce the differences among groups. 2) Contradictory results have emerged from studies of low-cloud anomalies and the fog-collection during El Niño (EN). EN increases water availability in fog oases when fog should be less frequent due to the reduction of low-clouds amount and stratocumulus. Because a minor role of fog during EN is expected, it is likely that measurements of fog-water collection during EN are considering drizzle and fog at the same time. Although recent studies on fog oases have shown some relationship with the ENSO, responses of vegetation have been largely based on descriptive data, the absence of large temporal records limit the establishment of a direct relationship with climatic oscillations. The second part of the results show that: 3) five different classes of different spectral values correspond to the main land cover of Lomas using a Vegetation Index (VI). The study case is characterised by shrubs and trees with variable cover (dense, semi-dense and open). A secondary area is covered by small shrubs where the dominant tree species is not present. The cacti area and the old terraces with open vegetation were not identified with the VI. Agriculture is present in the area. Finally, 4) contrary to the dry season of 2008 and 2009 years, a higher VI was obtained during the dry season of 2010. The VI increased up to three times their average value, showing a clear spectral signal change, which coincided with the ENSO event of that period.

Abstract:

The Adair Bay pozos (water holes) are small artesian springs scattered along the saltflats of the Gran Desierto near the coast of the Gulf of California in northwestern Sonora. The pozos provide essential fresh water for the rich bird fauna and some of the mammals, and were also utilized earlier by native people. The Gran Desierto aquifer appears to consist of sand and gravel deposited in ancient river beds which were subsequently overlain by dunes. Toward the coast, the alluvial aquifer becomes confined, or buried, beneath the relatively impermeable clays of the saltflats. These clays act as a barrier which causes artesian pressure to develop within the underlying aquifer. Pozos appear to develop at locations in which the permeability of the clay is increased, possibly by desiccation cracking or by flocculation due to ion exchange. The hypothesized existence of a buried fluvial system may explain the occurrence of clusters of pozos in some saltflats and their absence in many others, i.e., pozos only occur in saltflats with an underlying waterway. Alkali Weed (Nitrophila occidentalis) is the first plant to colonize places where the aquifer has broken through the overlying clays and reaches the surface or near the surface. This plant is a good indicator of fresh water. Coyotes seek fresh water in these places. Such action of coyotes and perhaps other animals seems to be related to the formation of smaller pozos. Saltgrass (Distichlis spicata) is the second plant to colonize a pozo and larger oases are colonized by a more diverse flora. The flora of the pozos is markedly different from that of the rest of the Sonoran Desert, both in life -form spectrum and geographic origin. The pozos support 26 species of vascular plants, many of which show temperate affinities. Several members of this flora are new geographic records: Indian Hemp (Apocynum cannabinum in the Apocynaceae), new for Sonora and the Sonoran Desert; Lythrum californicum in the Lythraceae, new for Sonora; Greasewood (Sarcobatus vermiculatus in the Chenopodiaceae), a new generic record for Mexico. The pozos are island -like relicts of the delta of the Colorado River. With the delta ecosystem now virtually destroyed, the local extinction of any wetland species in the pozo flora will most probably not be followed by new immigrants of the same flora, but by introduced weed species such as Salt Cedar (Tamarix ramosissima). The species -area relationship of the pozo flora is similar in value to that for other island ecosystems, although the exponential parameter (z = 0.263) is significantly higher than Preston's "canonical" value and the scale coefficient is significantly higher (k = 0.75) than those for other small island ecosystems. The species richness of a pozo is nearly four times higher than that of dry terrestrial islands of comparable size. Based on a projection of a biogeographical model fitted to the floristic richness of the pozos, we estimate that the original flora of the Colorado River delta supported 200 to 400 species of wetland vascular plants. Most of these populations have met local extinction with the destruction of the delta ecosystem of the Colorado River earlier in this century.

Abstract:

Le Tafilalet est une région du Maroc Saharien située dans le secteur sud-est, dans une zone frontalière, elle présente les signes d’un espace désertique fragile et marginalisé. Sa situation géographique, ses traits climatiques et son profil morphologique en font un espace structurellement vulnérable, qui n’offre que peu de chances au développement humain et économique. Pourtant, c’est un espace qui a pu briller et voir une période d’essor durant le Moyen Age. Celle-ci a connu le développement d’une grande civilisation de l’aride, dont les traits sont encore vivants dans le système de production agropastoral oasien. Ces particularités avaient permis l’établissement d’un équilibre fragile entre l’homme oasien, ses besoins et sa demande et un milieu fragile avec peu de capacités. Un équilibre rompu, depuis, par la modernité, l’exode rural, l’urbanisation et la salarisation. Nouveau arrivé dans le système économique oasien, le tourisme s’est développé à partir du début du XXème siècle, et a enregistré une importante évolution au point de devenir la première activité économique structurée du territoire. Le désert, les dunes, la palmeraie sont les grands atouts de ce produit, qui essaie de combiner, avec l’offre originelle paysagère, une offre culturelle constituée du bâtit, de la richesse humaine et tribale tout autant que par la commercialisation du désert comme espace ludique (circuit quad, VTT…). C’est ainsi que son produit s’affranchit des spots classiques du désert (dunes et dromadaire) pour s’ouvrir à un tourisme diffus, qui explore l’arrière pays, puisant dans la multi-activité et le ludique, l’immersion dans la vie quotidienne saharienne, le partage et l’échange culturel entre touristes et habitants. L’espace de notre étude autant que le secteur saharien, en globalité, se développe touristiquement, mais dans l’anarchie et la spontanéité. Le tourisme peut se révéler comme un facteur de menace pour la nature oasienne, son paysage, ses capacités en terme d’eau et de terre et son système de production agropastoral, majoritairement, vivrier et traditionnel…La mise en tourisme devra donc être rationnelle et bien contrôlée. Le développement du tourisme au Tafilalet passerait d’abord par une stratégie de développement durable. La place de la région, de l’acteur local sont très importantes, à nos yeux. Le développement devra, en ce sens, être appréhendé dans/ et par le territoire, comme espace de vie et d’action, loin des visions sectorielles qui n’avaient fait que prévaloir les zones utiles et marginaliser une bonne partie du territoire saharien. Cette approche doit interpeller aussi les spécificités de l’espace à la fois au niveau géographique et humain et mettre au centre de ses préoccupations la contrainte naturelle autant que la fragilité et la vulnérabilité environnementales… Des éléments qui ne peuvent être dissociés de la grande problématique du développement humain. Ce dernier est soulevé dans la thèse à travers la mise en lumière de l’importance de la participation citoyenne, déjà active et qui compte déjà plusieurs expériences à son actif. Le besoin de l’empowerment ou du renforcement de ses capacités, par la formation et le financement, est aussi soulevé pour révéler l’importance d’une action qui est déjà en germe et qui a besoin de soutien et d’accompagnement. En somme, le développement touristique dans les espaces sahariens, comme nous l’avons étudié à travers le cas de la région du Tafilalet, devrait rendre à l’homme oasien la place qu’il se doit d’occuper comme acteur dans son propre espace, à travers une stratégie de tourisme durable où le spatial autant que l’humain, l’économique et l’environnemental sont pris en considération. De fait, dans cet espace fragile et vulnérable les considérations environnementales et humaines sont aussi importantes que les variables de rentabilité, et devraient être au centre de toute réflexion sur le développement touristique territorial Tafilalet is a Saharan region of Morocco. Located in the south-east, in a border area, it shows signs of a weak desert space and a marginalized one. Its geographical location, climatic features and morphological profile make it a structurally vulnerable space, that offers little chance for human and economical development. Yet it was able to shine and experienced a boom during the Middle Age. This one has seen the development of a great arid civilization whose features are still living in the oasis agro-pastoral production system. These features have led to the establishment of a delicate balance between the oasis man, its needs and demand and a fragile environment with weak development capacities. Balance since broken by modernity, rural exodus, urbanization and salaried work. Newly arrived in the oasis economical system, tourism has developed from the early twentieth century and has undergone significant changes, to become the first formal economical activity in the area. The desert, the dunes, the palmgrove are the main advantages of this product which tries, increasingly, to combine with the original landscape offer a range of a cultural one consisting of the built heritage, human and tribes wealth as well as the commercialization of the desert as playful space (sport tours : quad, mountain biking ...). Thus the product is, gradually, free of the classical desert spots (dunes and camels) and the area opened to a an integrate and diffuse tourism, exploring the hinterland, drawing multi-activity, immersion in the Saharan and nomad daily life and a cross-cultural exchange between tourists and residents. The area of our study as well as the Saharan area in whole, live a touristic growth but in a kind of anarchy and spontaneity. In sum tourism can be, for several reasons, a threat factor of oasis nature, its landscape, its capacity in terms of water and soil and to the agro-pastoral production system, known to be mainly, a subsistence and traditional one. The development of tourism in Tafilalet region should happen through a strategy of sustainable development where tourism is approached by a territorial vision. The place of the local governance, the local actor are very important to us. Development must be understood in that sense in and for the territory as a space for life and action, away from sectors visions which had only prevailed useful areas and marginalized the majority of the Saharan territory. This approach should also call the specificities of this unique space both in geographical and human aspects. These ones should be in the center of its conception as well as the natural stress, the fragility and vulnerability of the environmental elements ... All of that cannot be separated from the problem of the human development. It is raised in this thesis through a highlight of the importance of citizen participation, already active and that has several experiences to its credit. The need to empower his action by training and funds may reveal the importance of an action that is already in germ and which needs to be supported and assisted. In sum, the development of tourism in the Saharan areas, as we have shown through the case of the Tafilalet region, should give the oasis-man his place as the first actor of his own development. This conception could be done through a strategy of sustainable tourism where the spatial as well as the human, the economical and the environmental elements are considered. In this fragile and vulnerable area human and environmental considerations are as important as profitability variables for any territorial tourism development strategy

Abstract:

Hur kommunicerar restauranger hållbarhet på sina webbsidor och hur kan den förstås? Syftet med studien är att undersöka hur restaurangerna Agrikultur, Amass, Credo, Oaxen och Relæ kommunicerar hållbarhet på sina webbsidor.Utifrån teorier kring Corporate Social Responsibility (CSR), branding och hållbarhet har vi utfört en semiotisk analys och undersökt fem nordiska restauranger som alla blivit tilldelade ”Sustainability Award 2019” av Guide Michelin.Genom att teoretiskt analysera restaurangernas material med hjälp av vårt analysschema, konstruerat av branding-teorier och semiotik visar studierna på att alla restaurangerna kommunicerar hållbarhet på flera olika sätt. Vissa restauranger kommunicerar sitt hållbarhets- och CSR-arbete redan i deras namn och logotyp medan andra restauranger behöver mer beskrivande bilder och texter i kombination för att ge en bild av deras hållbarhetsarbete. Slutsatsen är att det är viktigt att restaurangerna kommunicerar sitt hållbarhetsarbete eftersom detta är något som visar på deras höga positioner i restaurangbranschen. Vidare visar slutsatsen på problematiken att dela ut ett hållbarhetspris utan att specificera kraven. How do restaurants communicate sustainability on their websites and how can it be understood? The purpose of the study is to investigate how the restaurants Agrikultur, Amass, Credo, Oaxen, and Relæ communicate sustainability on their websites.Based on theories of Corporate Social Responsibility (CSR), branding, and sustainability, we conducted a semiotic analysis and examined five Nordic restaurants, all of which were awarded the Sustainability Award 2019 by Guide Michelin.By theoretically analyzing the materials of the restaurants by using our analysis scheme, constructed of branding theories and semiotics, the studies show that all the restaurants communicate sustainability in several different ways. Some restaurants already communicate their sustainability and CSR work in their name and logo. While other restaurants need more descriptive images and texts in combination to show their sustainability work. The conclusion indicates that it is important to communicate sustainability in the restaurant industry. Furthermore, the conclusion exposes the problem of awarding a prize for sustainability without specifying the requirements.

Abstract:

Dans ce travail de recherche, nous étudions les processus de changements récents qui ont eu lieu dans l’espace et la société touati, changements qui affectent l’écosystème oasien et qui mènent vers un nouveau rapport ville/campagne représenté dans la ville d’Adrar et ses nouvelles mises en valeur agricoles. Ces mutations se projettent d’une façon ou d’une autre sur l’espace agricole oasien et l’espace ksourien, où l’oasis est engagée dans une ouverture économique et sociale à grande échelle. Par conséquent, elle connaît une très forte pression démographique qui a résulté de l’accroissement spectaculaire récent de sa population. Ces mutations sont largement soutenues par une politique étatique. Dans un souci de créer une équité territoriale, les agglomérations sahariennes sont toutes dotées de fonctions de base (éducation, santé et administration) auxquelles s’ajoutent les programmes d’habitat planifié, collectif et individuel semblables à ceux du nord. De plus, compte tenu de la richesse de son sous-sol, le Sahara est appelé à contribuer à l’indépendance alimentaire du pays. À cet effet, des réformes agraires ont été spécialement instaurées afin d’encourager les sahariens à adopter les nouvelles mises en valeur et à passer aux nouvelles techniques de production et d’irrigation. Le but principal de notre étude est de savoir : Jusqu’à quel point l’État a réussi de redessiner l’espace et la société saharienne ? Et jusqu'à quel degré ces changements ont affecté l’habitat traditionnel, la petite production vivrière et les modes d’irrigation vernaculaires. Et finalement, l’État est-il arrivé à maîtriser et contrôler les nouvelles formes d’occupation du sol saharien ? In this research, we study the process of recent changes that taken place in the Touat’s space and society, changes that affect the oasis ecosystem and lead to a new relation between city/country represented in the city of Adrar and his agricultural development. These changes are projected in one way or another on the oasis’s agricultural land and the ksour’s space, where the oasis is engaged in a large-scale economic and social openness. Therefore, it is experiencing strong population pressure that resulted from the recent increase of its population. These mutations are largely supported by state policy. The state plans will draw a new landscape of Sahara. In a n effort to create a territorial equity, the Saharan cities all have basic functions (education, health and administration) plus the planned housing programs, collective and individual similar to the north. Furthermore, given the richness of his basement, the Sahara is expected to contribute to the country’s food independence. To this end, land reforms were introduced specifically to encourage the Sahara to adopt a new enhancement and move to new production techniques and irrigation. The main purpose of our study is to know: how far the state was able to redesign the space and the Saharan society? And to what degree these changes have affected the traditional habitat, the small food production and vernacular irrigation methods. And finally, did the state reached to control and verify the new forms of Saharan land?

Abstract:

Face à l’arrivée de technologies modernes d’exploitation des eaux souterraines plus propices à l’intensification culturale et aux initiatives privées sur de nouveaux espaces irrigués, le devenir des systèmes irrigués communautaires pose question. Dans cette thèse, nous proposons de renouveler le regard sur la façon dont les communautés d’irrigants s’emparent de la modernité, d’un côté pour renouveler leur système irrigué communautaire en adaptant les infrastructures et les institutions d’irrigation, et d’un autre côté, pour améliorer leur niveau de vie et leur statut social en saisissant les opportunités économiques de développer une agriculture de marché sur de nouveaux espaces irrigués. Ainsi, une lecture plus nuancée des transformations est possible pour décrire et analyser le renouveau des systèmes hydrauliques anciens sans oblitérer ni les continuités ni les ruptures qu’ils traversent, y compris quand cela concerne la juxtaposition de systèmes « traditionnels » et « modernes ». Ce travail s’est focalisé sur le territoire oasien de Sidi Okba dans le Sahara algérien. Ce territoire est intéressant pour notre étude par le fait que l’utilisation de technologies modernes d’exploitation des eaux souterraines profondes a contribué activement à transformer son système irrigué communautaire d’épandage de crue en deux espaces irrigués distincts : l’ancienne palmeraie où la communauté continue à irriguer collectivement et les extensions où l’agriculture se fait à partir de forages privés. Ce territoire est complexe par la mobilisation de plusieurs ressources en eau - lâchers et fuites du barrage, eaux souterraines des nappes phréatique et captive-, mais également par la juxtaposition de deux formes d’agriculture sahariennes. Pour dénouer l’écheveau de cette complexité, dans le temps et dans l’espace, nous avons développé un cadre d’analyse interdisciplinaire et multiscalaire. Ce cadre nous a permis de montrer, premièrement, les capacités de renouvellement agricole après l’effondrement du système irrigué communautaire d’épandage de crue. La communauté a su saisir les opportunités pour développer une agriculture de marché dans les nouveaux espaces irrigués tout en maintenant une organisation familiale héritée de l’agriculture oasienne traditionnelle. Deuxièmement, la mobilisation de l’eau souterraine profonde a permis d’éviter le déclin de l’ancienne palmeraie. Nous avons montré l’importance des adaptations des infrastructures d’irrigation en plus du façonnage des règles dans le renouvellement du système irrigué collectif. Troisièmement, notre analyse a montré comment l’irruption de technologies modernes de pompage et les opportunités socio-économiques dans les nouveaux espaces irrigués, ont infléchi, transformé et accéléré la recomposition des relations sociales dans le système irrigué communautaire de l’ancienne palmeraie. Quatrièmement, notre analyse a permis d’illustrer la continuité territoriale entre les deux espaces irrigués. Ainsi, les nouveaux espaces irrigués sont une creatio ex materia du système oasien traditionnel de Sidi Okba. À travers notre recherche, nous concluons qu’il est important de considérer les anciens et les nouveaux espaces irrigués comme un seul et même territoire hybride en reconnaissant à la fois la complexité territoriale, l’hybridité dans chaque espace, et les interactions existantes entre les systèmes traditionnels et modernes. Le cadre d’analyse développé dans cette thèse offre les outils nécessaires pour lire et comprendre le renouveau des systèmes irrigués communautaires pour faire face à des vulnérabilités climatiques, environnementales, écologiques et socio-économiques bien réelles The future of community-managed irrigation systems is increasingly questioned with the arrival of modern technologies of groundwater exploitation, more conducive to crop intensification and to individual initiatives. In this thesis, we develop a methodology to investigate how irrigation communities seize ‘modernity’ to, on the one hand, renew their community-managed irrigation system by adapting the infrastructure and the irrigation institutions, and on the other hand, to improve their living standards and social status by seizing the economic opportunities to develop a market agriculture on new irrigated spaces. A more nuanced reading of the transformations is, therefore, possible to describe and analyze the renewal of ancient hydraulic systems without obliterating neither the continuities nor the ruptures that they traverse, even in case of the juxtaposition of ‘traditional’ and ‘modern’ systems. This research focused on the Sidi Okba oasis in the Algerian Sahara. This territory is interesting for our study as the use of modern technologies for deep groundwater exploitation contributed actively to transform its community spate irrigation system into two separate irrigated spaces: the ancient palm grove where the community continues to irrigate collectively and the extensions where agriculture is based on private tube-wells. This territory is complex by the mobilization of several water resources (dam releases, dam leakages and groundwater exploited from phreatic and confined aquifers), but also by the juxtaposition of two forms of Saharan agriculture. To unravel the complexity, in time and space, we developed an interdisciplinary and multi-scalar analytical framework. This framework allowed us to show, first, the capacity for agricultural renewal after the collapse of the community spate irrigation system. The community seized opportunities to develop a market agriculture in new irrigated areas while maintaining a family organization inherited from traditional oasis agriculture. Second, the availability of pumped groundwater enabled the survival of the ancient palm grove. We showed the importance of adaptations of irrigation infrastructure in addition to crafting the rules in the renewal of the collective irrigation system. Third, the use of the analytical framework revealed how the irruption of modern pumping technologies and socio-economic opportunities in the new irrigated spaces modified, transformed and accelerated the restructuring of social relations in the community irrigation system of the ancient palm grove. Fourth, our analysis illustrated the territorial continuity between the two irrigated spaces. Thus, the new irrigated spaces are a creatio ex materia of the traditional oasis system of Sidi Okba. Through our research, we conclude that it is important to consider the ancient and new irrigated areas as one and same territory by recognizing both territorial complexity, hybridity in each space, and existing interactions between traditional and modern systems. The analytical framework developed in this thesis offers the necessary tools to read and understand the renewal of community-managed irrigation systems in order to face the current profound climatic, environmental, ecological and socio-economic vulnerabilities

Abstract:

Cette recherche vise à identifier le champ disciplinaire de la morphologie urbaine. Notre démarche morphologique étudié plusieurs éléments : l’étalement urbain s’implante autour de l’oasis de l'intra-muros à la périphérie par ces capacités des ses zones nouvellement urbanisés Notre analyse porte sur la ville contemporaine, marquée par la mutation des territoires sahariens et la nouvelle configuration des espaces urbains modernes, où la grande concentration de population a profondément déstabilisé le paysage organique de l’oasis. L’analyse morphologique permet aussi d’évoquer les positions d’aménagement et d’urbanisme d’origine étatique algérienne, relevant de la promotion de l’oasis en chef-lieu de wilaya, et de la proximité du pôle d’hydrocarbures de Hassi R'mel ; qui participent à l’affirmation de l’image du pouvoir économique et politique de l’Algérie nouvelle. En montrant son relatif délaissement, en particulier par la planification urbaine trop décalé de la théorie traditionnelle urbaine. D’où un manque d’attention portée aux recherches de morphologie urbaine effectuées à l’étranger aux recherches des oasis de la région en Maroc et Tunisie. Mais aussi cette recherche met l’évaluation au regard du modèle sont des modèles algérien des oasis de Ghardaïa, Béchar et Biskra pourrait éclairer les politiques d’aménagement par les enjeux urbanistiques. Cette approche stimulante rendant compte du renouvellement physique des villes comporte pourtant des dimensions à la fois théorique, déductive et dynamique. Le modèle des oasis est donc pertinent, mais aussi les limites du modèle urbain moderne de l'agglomération nouvelle soulignées comme modèles urbains dans le contexte algérien du renouvellement urbain. L’évaluation de ce modèle en Sud de l'Algérie pourrait éclairer les politiques d'aménagement par les enjeux de l'institutionnalisation du concept de développement durable et la construction durable qui réduit les coûts et assure une efficience énergétique idéale sa mise en pratique peuvent apporter certaine élément d'éclairage(écotourisme, modernisation des techniques d'irrigation , réemployer des matériaux du construction de ressources locales quand aux développement futur des ces villes sahariennes This search aims at identifying the disciplinary field of the urban morphology. Our morphological approach studied several elements: the urban spreading becomes established around the oasis of the intramural in the periphery by these capacities of its zones recently urbanized Our analysis concerns the contemporary city, marked by the transformation of the Saharan territories and the new configuration of the modern urban spaces, where the big concentration of population profoundly destabilized the organic landscape of the oasis. The morphological analysis also allows to evoke the positions of development and town planning of Algerian state origin, being a matter of the promotion of the oasis in administrative center of wilaya, and the closeness of the pole of Hassi R' mel's hydrocarbons; which participate in the assertion of the image of the economic and political power of new Algeria By showing his relative solitude, in particular by the urban planning too much moved by the urban traditional theory. Where from inattention impact in the searches for urban morphology made abroad in the searches for the oases of the region in Morocco and Tunisia. But also this search puts the evaluation with regard to the model are models Algerian of the oases of Ghardaïa, Béchar and Biskra could light the politics of development by the urbanity stakes. This stimulating approach reporting the physical renewal of cities contains nevertheless at the same time theoretical, deductive and dynamic size. The model of oases is thus relevant, but also the limits of the modern urban model of the new urban conglomeration were underlined as urban models in the Algerian context of the urban renewal. The evaluation of this model in the South of Algeria could light the politics of development by the stakes in the institutionalization of the concept of sustainable development and the sustainable construction which reduces the costs and assures an ideal energy efficiency its application can bring certain element of lighting (ecotourism, modernization of the techniques of irrigation, to reuse materials of construction of local resources when in future development of these Saharan cities

Abstract:

Cette thèse porte sur un espace oasien (une terre agricole encore en état de production) qui tend à s’urbaniser de manière informelle : l’oasis de Zrig, dans le Sud-est de Gabès, en Tunisie. L’habitat qui s’y développe prolifère sans permis de construire depuis 1980. Dans ce nouvel espace urbain se développe une double marginalisation sociale touchant aussi bien les paysans qui ont perdu leurs terres que les nouveaux venus aux ressources souvent précaires. L’environnement et le patrimoine agricole local en pâtissent également. Zrig est un détail (au sens pictural) du devenir de l’oasis de Gabès. Un travail de recherche sur l’espace de Zrig et ses transformations se rapproche de la chronique d’une dégradation annoncée. Il y a, en effet, dégradation à deux niveaux : la transformation d’un espace oasien en un espace urbain difforme et le développement de pratiques socio-économiques informelles liées aux stratégies des nouveaux arrivants et aux rapports qu'ils entretiennent avec les autorités locales.Ce travail s’appuie sur les résultats d’une enquête de longue haleine que j'ai effectuée de 2010 au 2016 auprès des habitants de Zrig, ceux d’hier et d’aujourd’hui, afin de recueillir leurs représentations des transformations spatiales et sociales qui ont affecté l’oasis. Il constitue également une étude des modes de construction de logements informels et une analyse des stratégies perpétuant cette pratique mise en œuvre par les nouveaux venus This dissertation relates to an oasis area (a still productive agricultural land) which is being informally urbanized: in the Zrig oasis, south-east of Gabes, the habitat has proliferated without building permit since 1980.In this new urban space, a double social marginalization affects farmers who lost their land as well as newcomers with often precarious resources. The environment and the local agricultural heritage are also impacted.Zrig is a detail (in apictorial sense) of the future of the Gabes oasis. A research work on the space of Zrig and its transformations resembles the chronicle of an announced degradation. Indeed, the degradation can be identified at two levels: the transformation of an oasis area into a deformed urban space, and the development of informal socio-economic practices related to the strategies of space occupants and to their relations with local authorities. In addition to the data provided by official and academic surveys, this work is based on the results of a long-term survey that I conducted from 2010 to 2016 Zrig, those of yesterday and those of today, in order to collect their representations of the spatial and social transformations that affected the oasis. But also to study the building practices of informal settlement sand the strategies of newcomers for this purpose

Abstract:

Les ovins D’man sont élevés dans les oasis tunisiennes selon un rythme accéléré permettant d’avoir trois agnelages en deux ans. En plus des effets directs du mode d’élevage et d’environnement exercés sur les brebis D’man, la prolificité élevée pose question quant à la survie, la croissance et le bien-être des agneaux. L’objectif de ce travail est de déterminer les facteurs de risque qui affectent la survie et la croissance chez les agneaux D’man élevés dans les oasis de Gabès. Dans une première étape, le travail a traité les facteurs de risque d’ordre zootechnique et environnemental sur la base des données concernant 1189 agneaux élevés à la ferme de l’OEP de Gabès. En moyenne, un taux de mortalité égal à 13,4% a été observé de la naissance au sevrage dont 41% pendant les 10 premiers jours de vie, 29% entre 10 et 30 jours et 30% entre 30 et 70 jours. Le taux de mortalité est plus élevé chez les agneaux nés en hiver (23,5%) par comparaison au printemps (12,3%), l’automne (10,2%) et l’été (9,5%). A cause de leur poids léger, les agneaux issus des portées multiples (triples et quadruples) ont un taux de mortalité plus élevé (52,2%) comparés à ceux issus des portées simples et doubles ayant un poids de naissance medium (24,4%) ou lourd (1,8%). Les agneaux nés en printemps sont plus lourds à la naissance, à 30 et 70 jours et par conséquent ont des vitesses de croissance plus importantes par comparaison aux agneaux nés en hiver, en automne et en été. Le poids à la naissance et les vitesses de croissance sont également influencés par la taille de portée et l’âge de la brebis. Le faible poids à la naissance (≤ 1,5 kg), les portées multiples (quadruples et quintuples) et les agnelages d’hiver sont les principaux facteurs de risque pour la survie et la croissance des agneaux D’man D’man ewes are reared in Tunisian oases under an accelerated management system allowing breeders to have three lambing periods every two years. High prolificacy may accentuate the detrimental effects of an accelerated lambing system through problems which affect growth, welfare and survival. Therefore, the aim of the present study was to determine the risk factors of lamb mortality in this prolific breed maintained under intensive management in Tunisian oases. In a first step, growth and mortality rates are reported using records of 1189 lambs collected between 2004 and 2009 from an accelerated lambing system to determine risk factors according to characteristics of the animals and the environment. Results showed that overall mortality from birth to 70 days of age was 13.4%. Of all the total losses, 41% of the lambs died within 10 days of birth, 29% died between 10 and 30 days of age and 30% between 30 and 70 days. Mortality rate was significantly higher in winter (23.5%) than in spring (12.3%), autumn (10.2%) and summer (9.5%). Lambs in the low-weight category died more frequently (52.2%) than lambs from medium-weight (24.4%) to high-weight (1.8%) categories. Lambs born in spring were consistently the heaviest at birth, at 30 and 70 days of age with the greatest average daily gains compared to those born in winter, autumn and summer. Birth weights were affected by litter size and ewe age, and lambs from older ewes (2-10 years) grew faster than lambs born from young ewes (1 year). The principal risk factors identified were season (winter), birth type (multiple) and weight class (≤ 1.5 kg)

Werden Defizite in Bewässerungssystemen als rein technisches Problem betrachtet, führt dies zur Ausblendung sozialer und kultureller Aspekte der Ressourcenverwaltung. Als Konsequenz werden sinnvolle technische Innovationen von der Bevölkerung nicht angenommen und verbleiben letztendlich ungenutzt. Bisherige Studien über das südmarokkanische Oasengebiet im Ziz-Tal hatten überwiegend ökologische und ingenieurtechnische Ansätze verfolgt. Das Forschungsinteresse dieser Arbeit liegt stärker auf den kollektiven Handlungsmustern, Regelsystemen und spezifischen Variationen sozialer Vereinbarungen in Form von formellen und informellen Institutionen der traditionellen und der heutigen Bewässerung. Zum Verständnis der gegenwärtigen Situation werden die rechtlichen und politischen Rahmenbedingungen, der soziokulturelle Kontext sowie die naturräumlichen Voraussetzungen und Umweltveränderungen – mit besonderem Blick auf die verfügbaren Wasserressourcen in dieser ariden Region – analysiert und das institutionelle Gefüge in einer auf Methoden der qualitativen Sozialforschung basierenden Fallstudie in einem Oasendorf untersucht.

Abstract:

Notre thèse envisage la production écrite en classe de français comme une pratique scolaire novatrice lorsqu’elle est accomplie au sein d’un espace-atelier et réalisée par l’entremise du jeu, de la mise en scène et du montage d’un spectacle. Pour ce faire, nous avons mis en œuvre une pièce de théâtre, Caligula d’Albert Camus, comme moyen d’enseignement-apprentissage, en l’accompagnant d’une gamme d’outils –dispositif ou unité didactique, vidéo de la pièce, carnet de bord, etc., – favorisant en parallèle une recherche-action sur terrain. Notre travail questionne en outre la possibilité d’une telle expérience menée dans un lieu peu commun, le Sud de l’Algérie, dans l’oasis de Bou-Saâda, et auprès d’un groupe d’apprenants d’une classe de 2e année Langues Étrangères au lycée. Nos objectifs sont de cultiver la compétence écrite chez l’apprenant oasien via l’écriture théâtrale, de lui donner goût à l’apprentissage de la langue et de conférer une certaine dynamique à cet apprentissage en lui permettant de créer et de voir représenté ce qu’il écrit sur le plateau. Au-delà d’une simple acquisition de compétences rédactionnelles, nous avons pu constater des mutations dans les représentations scolaires et sociales de la langue française chez le groupe-apprenant, issu d’une société sudiste conservatrice, chez qui la langue-cible a un statut différent de celui dont elle bénéficie au Nord, ce qui renvoie, par là même, à l’histoire, à la géographie et au plurilinguisme du pays Our thesis considers the written production, in a French class, as an innovative school practice when it is accomplished in a workshop space, and realized through the play, staging, and editing of a show. In order to do this, we have implemented a play, Caligula by Albert Camus, as a way of teaching and learning, accompanied by a range of tools - a teaching device or unit, a video of the play, Logbook, etc., - promoting, at the same time, an action research on the ground. Our work also questions the possibility of such an experiment conducted in an unusual place, the South of Algeria, in the oasis of Bou-Saâda, and with a group of learners 2nd Year, Foreign Languages in high school. Our aims are to improve the written skills of the oasis learner through theatrical scripture, to give him a taste to learn the language; and to give a certain dynamic to this learning by allowing him to create and see represented what 'He writes on the set’. Beyond a simple acquisition of editorial skills, we have seen changes in the academic and social representations of the French language in the learner group, from a conservative Southern society, in which the target language has a different status has the respect to the North, evoking the history, geography and multi-linguals of the country

碩士 國立中山大學 海下技術研究所 87 The purpose of this study is to understand the wave propagation in various environments. The first part of this thesis is to investigate the wave propagation in stratified media. First we describe the mathematical model for acoustic propagation in stratified media. Then several cases will be discussed by using existing software OASES. In this research, we will focus on reflection coefficient and transmission loss of stratified environment. By dividing ocean into more layers, a close-to-real ocean environment can be approximate. The geoacoustic model for this ocean environment is based on Hamilton's study, which provided complete acoustic properties of the sea floor. The second part of this thesis is to investigate the wave propagation when the characteristics of the ocean acoustic waveguide vary with a horizontal range. We will drive the acoustic pressure by using Normal Mode Method and Reference Waveguide Method, and the shear stress is not included. The case study of this part will discuss the effects of a small slope of the sea bottom and a small horizontal gradient of the sound velocity for various acoustic parameters. The numeric computation software MATLAB will be used to calculate the transmission loss.

Abstract:

Gli effetti catastrofici dell'Antropocene sono sempre più evidenti. Le manifestazioni di crisi non sono solo ambientali, ma anche economiche, sociali, politiche, etiche; che combinate con gli immaginari distopici del futuro, suggeriscono la necessità di un cambio di paradigma. A questo riguardo, i Commons sono visti come un'alternativa per una transizione verso un'economia post-capitalista. In questo contesto dell'Antropocene, il Design per l'innovazione sociale rimane inteso come un'azione "umanitaria", legata alla logica della mercificazione; motivo per cui alcuni chiedono di decolonizzare il Design dalle astrazioni occidentali. La ricerca si è concentrata sul rapporto tra Design e Commons, con un'attenzione al pensiero decoloniale. L'idea è quella di comprendere il ruolo del Design nel contribuire a spostare i paradigmi da un'economia di crescita estrattivista a un'economia delle risorse; un design legato alle situazioni invece che agli oggetti. L'indagine ha seguito un approccio di ricerca-azione che prevedeva di "abitare" le oasi di Chenini e Jemna in Tunisia, come Commons/Community Economies in crisi. È stato condotto un esperimento di design collaborativo utilizzando una linea di pensiero post-sviluppista/femminista, considerando i concetti di "Radical Imagination", "Epistemologies of the South" e "Situated Knowledge". Ne è emersa una prospettiva diversa per la ricerca progettuale, realmente radicata nel presente e capace di portare le comunità e i contesti coinvolti verso un futuro realizzabile.
