Full textAbstract:
There is scientific consensus that anthropogenic climate change is occurring and that it has had and will continue to have profoundly negative social, economic, and environmental consequences. The US government has not taken sufficient action to mitigate the threat of dangerous climate change. Frustrated by the lack of action in the legislative and executive branches, climate advocates have turned to the judicial branch and litigation to advance their cause. Litigation is important not only for its ability to create substantive legal change, but also for its power to generate media coverage and shape public and political discourse. There is growing recognition of the important contributions psychology can make to the study and practice of law. Research in psychology helps illuminate why the US public has had trouble engaging with the science of climate change, understanding the risks posed by climate change, and feeling motivated to take corrective action. Research also shows that how a public health issue is framed powerfully shapes the public debate and policy prescriptions for that issue. This thesis examines how climate advocates can construct their litigation messaging in light of insights from psychological and framing theories to most effectively advance the climate movement in the US. I chose to analyze three climate change litigation strategies that might present an opportunity of overcoming the public’s psychological hurdles to engaging with climate change and offer a narrative on climate change that would resonate with the public. In conducting my analysis, I found that, if used effectively, the medium of litigation offers a unique opportunity to reframe climate change and overcome the public’s cognitive hurdles to perceiving the true dangers of climate change. The structure of litigation, which requires plaintiffs to trace their injuries—including economic, social, and health-related injuries—to the actions of defendants, allows climate advocates to leverage insights from framing and psychology to make their climate change narratives as salient as possible.Law, Peter A.

Full textAbstract:
Climate change is now an issue of critical concern throughout the world. In 2014, the Fifth Intergovernmental Panel on Climate Change proclaimed that the 21st century will pose some of the most acute challenges due to the accelerating impacts of climate change. Bangladesh, a South Asian developing country, is considered the sixth most vulnerable nation in the world due to its geographical settings (GCRI, 2015). The country faces extreme climatic events including sea level rise, salt water intrusion into arable lands, and the increased risk of severe storms, cyclones, floods, flash floods and drought in coming decades (IPCC, 2014; BCCSAP, 2009). The nexus between poverty and climate change is also a major concern, especially in a country like Bangladesh where lack of resources is a significant problem in both rural and urban areas. Therefore, climate vulnerability in Bangladesh is strongly associated with poverty, which in turn shapes its adaptation capacity. Climate change affects a wide range of communities in Bangladesh such as peoplew living in coastal zones, drought prone areas, settlers on unstable slopes and climate refugees in urban slums. However, among those affected, women are more vulnerable than men to climate change impacts, as is evident from the history of climate-induced disasters in the country. In Bangladesh, climate change increases women’s socio-economic vulnerabilities by directly impacting on their families’ food security, water consumption and traditional livelihood. According to Jahan (2008), any type of environmental degradation causes more suffering to women because their family’s survival, for which they are responsible, depends directly on the natural resource base. In the quest for a new livelihood, men migrate while women are often left behind to support their families and households. Thus women have had to develop a wide range of coping and resilience strategies in order to survive climate change impacts, and they have developed strategies and knowledge that can be particularly useful in establishing successful climate adaptation programs.Thesis (PhD Doctorate)

Lee, Eugenia. "Stories in the data: An analysis of climate change visualisations in online news." Thesis, The University of Sydney, 2018. http://hdl.handle.net/2123/20298.
Full textAbstract:
This thesis explores the way journalists are using and adapting visualisations in climate change news, in order to investigate the meaning-making potential of an emerging form of digital journalism where methods of information visualisation are used to translate specialist knowledge and often complex, multivariate datasetsinto images that are more easily understood by, and of social value to, the general public. Applying a dual methodological framework of heuristic evaluation and social semiotic analysis, this thesis presents a novel method of exploring both the abstraction and translation of climate change data into multimodal visual displays of quantitative information. By conducting a content and textual analyses of 547 climate change visualisation stories collected in the year of 2015 from seven Western generalist news publications that have made a commitment to excellence in data journalism, this thesis found that despite the steady rise in the popularity of data journalism, journalists are not widely adopting scientific methods of data analysis and representation. Over half of the visualisations examined were sourced from science communicators and government bodies, reinforcing traditional news power relations. Further, the textual analyses found that visualisations operate discursively. Rather than present data in systemised, interactive ways, journalists are retaining a large degree of narrative control over the way meaning is construed with and through the use of visualisations. These stories thus illustrate a continuation of, rather than a digital break with, traditional journalism. Such findings pose a challenge to the normative assumptions that data journalism adds value to news by improving its openness, transparency, accountability, and accuracy.

Thesis, Linköpings universitet, Tema Miljöförändring, 2021. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-176669.
Full textAbstract:
This thesis identified dominant discourses in climate change mitigation policy in three Swedish municipalities using argumentative discourse analysis. It was explored how these discourses influence the potential for success in mitigating climate change. Other studies have identified several factors that are important when working with climate change mitigation in municipalities, for example, political leadership and organizational structure. However, studies have shown that discourse is also an influential factor since it sets the frame for what can be thought of, consequently influencing policies and actions, but this has not been studied as much at the municipal level in Sweden. Previous studies of environmental policy have shown the dominance of an ecological modernization discourse, where economic growth and environmental issues are combined to create a win-win. The results in this thesis show the dominance of a strong ecological modernization where the decoupling between economic growth and environmental problems, renewable energy and technology, a global justice perspective, and a focus on collaboration between stakeholders is central. A main conclusion is that the ecological modernization discourse risks obscuring potential solutions that are not related to the market or technological innovation. However, the inclusion of a diversity of actors and a focus on justice could potentially minimize this risk. Finally, emerging discourses around transformation and circular economy could be ways to problematize the taken-for-granted ecological modernization discourse. However, their potential depends on how these concepts are framed and what is included in them.Presentation was done online due to COVID-19

Full textAbstract:
The main purpose of this research is to investigate the climate change and carbon reporting practises of UK FTSE 350 companies. The objectives cover three main areas of investigation including the extent of carbon reporting in the first mandatory year as compared to a voluntary year; the common stories told in companies’ climate change and carbon disclosure; and the dynamic of carbon reporting implementation, including the motivations for disclosure, the problems and issues faced and the disclosure implementation approach. Using storytelling as a theoretical lens, this research explore the content of disclosure, presentation and the motivation for disclosure using the storytelling concept. The data for this study was gathered through two sources: companies’ disclosure in annual reports, sustainability reports, websites and other online reporting; as well as interviews. The findings reveal that the introduction of Mandatory Carbon Reporting Requirements (MCRR) does improve the content and presentation of the companies’ carbon disclosure in annual reports, thus fulfilling the objective of the legislation in encouraging reporting and promoting transparency. The study has also found that the common story themes reported in companies’ disclosures relate to stories of climate change, emissions performance and reduction, and companies’ achievements in climate change and related areas. The findings of the study also demonstrate that maintaining a good reputation, complying with regulation, fulfilling stakeholders’ expectation, improve efficiency and cost saving, and projecting morality of management are the main motivations for climate change and carbon disclosure. It was also found that data collection and accuracy are perceived to be the most challenging issues faced by companies in disclosing their emission data, especially if they operate internationally. Last but not least, the findings show that companies will consult or choose to outsource their carbon disclosure or data collection to third parties when they do not have sufficient in-house resources and expertise.

Jones, Jocelyn. "Thinking with stories of suffering : towards a living theory of response-ability." Thesis, University of Bath, 2008. https://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.488897.
Full textAbstract:
In the thesis I develop a living theory of responsibility, movement, engagement, withdrawal, and self care with a living standard of judgement of response-ability toward the other. I use a hermeneutic phenomenological approach to develop a dynamic, relational understanding, where social constructions are discussed and refined using cycles of loose and strict thinking, an inter-play of emotion and intellect, and a combination of intuitive and analytic reasoning. This is underpinned by an extended epistemology embracing experiential learning, documentary and textual analysis, presentational knowing, dialogue, narrative and photographic inquiry. I address the essence of inquiry with people who have difficult stories to tell and for us to comprehend: narratives which emerge from episodes of chaos and suffering, interspersed with occasional glimpses of the inter-human. Within this context I explore responsibility [response-ability] to ‘the Other’ as subject, and the ethical obligations implied in that relationship. My and others’ narratives, through space and over time, are researched using an extended epistemology and inquiry cycles across two interwoven strands. I look back over a long career and ‘epiphanous’ moments as a social worker and academic in the field of child protection and children and families work; and as the child of a war veteran, I reflect on World War II narratives of suffering, changing identity, and the inter-human. This first and second person inquiry extends outwards through cycles of dialogue with ex European prisoners of war and relation with landscape across Europe and Russia. In these reflections I clarify my meanings of chaos, suffering and responsibility [response-ability]. The learning from this extended inquiry and the contribution to knowledge are reflected on within my current practice as a participative researcher who is expressing response-ability toward the other. Finally, I consider implications for improving practice and organizational climate in children and families work.

Matthews, Kellianne Houston. "Making Old Stories New in the Anthropocene: Reading, Creating, and the Cosmological Imagination in Darren Aronofsky's Noah." BYU ScholarsArchive, 2017. https://scholarsarchive.byu.edu/etd/6861.
Full textAbstract:
This thesis examines Darren Aronofsky's 2014 film Noah as a pattern for metafictionalizing narratives into thinking stories as we confront the uncertainty and challenges of the Anthropocene. While Ecocriticism has sought for the development and promotion of nature writing and environmentally oriented poetry and fiction- "new stories" that will shape a stronger environmental ethic"”it has placed too much responsibility for the environmental imagination on what we read rather than on the more important question of how we read. My argument addresses the readerly responsibilities that, if met, have the power to transform old stories and old habits of mind into environmentally relevant attitudes and behaviors. The search for new stories, in other words, although important, has tended to understate the responsibility of the reader to make stories new and to read them as cosmologies that pertain to our contemporary situation. What is needed are new ways to read and engage with stories, new reading methods to metaphorize narratives themselves, making them metafictional even when they are not. Now, in an age of climate change and environmental degradation, it is time for us to think about stories in relation to our role as protagonists in the story of the earth, imagining new possibilities and actively accepting our role of writing our story anew. I hope to demonstrate that this type of aggressive reading of even popular culture (often regarded as mainstream, or "œthoughtless" stories) can mine the necessary insights to reexamine humanity's relationship with the earth and its inhabitants.

"Underreported Stories on Climate Change and Coral Reefs in These Times of Diminishing International Reporting| Mining the Scholarly Literature Through Regular Annotated Bibliographies." Thesis, University of Colorado at Boulder, 2014. http://pqdtopen.proquest.com/#viewpdf?dispub=1558673.
Full textAbstract:
The goal of this project is to explore solutions to the increasingly difficult challenge of covering international environmental topics, such as coral reefs and climate change, during times of constrained budgets, shrinking environmental reporting, and disappearing foreign news bureaus. In this context of limited resources, this study explores whether the periodic bibliographic review of scholarly literature may offer a low-expense avenue for news organizations to sustain or even increase the breadth and depth of coverage of these important topics. This study compares coverage of coral reefs and climate change in scholarly journal articles (2007–2011) to those in the popular press (2007–2012) using the New York Times (NYTimes) as an exemplar of the latter. The extra year in the latter was to allow for a possible time lag in information moving from the scholarly literature to the popular press. Articles on coral reefs and climate change identified in the scholarly literature (239) revealed numerous possibilities for stories that were not covered in the 22 annotated articles on this topic that appeared in the NYTimes. Whereas the most frequently discussed topics in the scholarly literature were the relationship between herbivorous fish and coral health, sea surface temperatures (SST), coral bleaching, and the resilience, recovery, and acclimation processes of coral reef ecosystems, the NYTimes's articles focused on conservation, tourism, SST, and broad discussion of climate change and how it might affect coral reef ecosystems. Additionally, of the 22 NYTimes articles on coral reefs and climate change, only three (14%) included hyperlinks to scholarly articles and 12 (55%) included at least one scientific reference. Overall, this study demonstrates that during these times of declining resources for on-the-spot reporting, scholarly literature represents an affordable but currently underutilized means for news organizations to continue providing wide ranging and detailed coverage of international environmental issues.

La Linea di Brandt divide il mondo in due parti, ricchi e poveri. Oltre alle condizioni economiche, ci sono altri aspetti più complessi che oggi definiscono uno stato weak o strong, come ad esempio le sue condizioni politiche e sociali. In relazione a ciò, verrà condotta una ricerca ed uno studio sugli effetti del riscaldamento climatico sugli stati sviluppati ed in via di sviluppo. La questione principale, infatti, sarà se il riscaldamento climatico, contribuisce ad incrementare la disuguaglianza tra weak e strong states. Per dimostrare ciò, verrà condotta un’analisi relativa agli effetti causati da un evento climatico, ovvero l’uragano. Alcuni scienziati, sono ancora scettici nel confermare che gli uragani aumentano di quantità a causa del riscaldamento globale, ma è stato invece dimostrato che possono aumentare per quanto riguarda l’intensità, a causa dell’aumento del livello del mare e delle temperature sempre più elevate. Il caso studio, si focalizzerà su una valutazione dei danni e della resilienza di Haiti considerato weak state e della Florida considerata strong state, al fine di poter contribuire alla letteratura già esistente in materia e di fare una comparazione tra i due paesi. Grazie a questa valutazione, si potrà comprendere se, con il passaggio dell’uragano, e quindi a causa del riscaldamento climatico, si verifica un effettivo aumento delle disuguaglianze.

Full textAbstract:
A substantial segment of the error in numerical weather prediction and climate projections comes from the intrinsic uncertainties of General Circulation Models of the atmosphere. Stochastic physics schemes are one of the preferred methods to represent the model uncertainty in Ensemble Prediction Systems, where different realizations of the same forecast are created to quantify the probabilities of different outcomes in the atmospheric flow. Stochastic physics schemes have been successfully employed in medium-range and seasonal forecasting systems, as they increase the skill of probabilistic forecasts. Similarly it has been demonstrated than these schemes can improve certain aspects of the model's climate. However, it is still not clear whether they are a truthful representation of the model uncertainties they aim to represent. In this thesis, a collection of stochastic physics schemes are evaluated using a seamless approach. It is found that they can improve the representation of the tropical climate and extra-tropical cyclones, but they degrade the individual representation of these processes deteriorating the deterministic skill of the model. Some important features of the model can be degraded by the stochastic physics schemes, like energy and moisture conservation on climate scales. Some closures to the schemes are proposed and successfully tested to remove or reduce some of the problems found. Alternative approaches in the development of stochastic parametrizations are also investigated. Stochastic physics schemes have some benefits but still require further development to produce a realistic representation of model error. It is also recommended that evaluation methodologies must be expanded to include process-based diagnostics to display the realism of its perturbations.

Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1989.Includes bibliographical references (leaves 122-125).
This thesis discusses passive and low energy cooling strategies and systems in hot arid climates. The choice of a certain strategy, as well as determining the appropriate cooling schemes for such a context becomes of prime importance in developing the optimum energy conscious building design. The motivation for working in this area of research stems for the need facing architects to start developing a serious sense for energy considerations in their architectural design, especially in existing and multi-storey buildings. Here, in this research, the different factors that govern the control of heat gain through the envelope of the building will be analyzed. Also, solutions to minimize the cooling load for dwellings will be suggested/provided; by means of selecting the adequate cooling systems (evaporative, convective, and radiative) that promote the optimum desired thermal comfort. This research concludes its technical analysis with an architectural design for two schemes; The first is a cooling system that can be applied to new buildings, or retrofitted to existing ones. It uses evaporative coolers and solar chimney systems at daytime. It also uses night-time forced ventilation to cool the ordinary slab. The second can be applied in new buildings. It uses evaporative coolers and solar chimney systems at day-time. It also uses night-time forced ventilation through cored slabs. This design, and these schemes, are perceived as a starting point for further development and more research.

Full textAbstract:
The history of mining exploration has left a significant stock of legacy contamination in the UK’s river sediments. Flood events have contributed to the erosion of upstream sediment deposits and widespread the contamination throughout river basins, carrying mining legacy sediments to lowland rivers and estuaries. This thesis investigates how the increase of climate change effects could disturb the mining legacy deposits and the consequences for the river health. The physical characteristics and the proximity to the Tamar Estuary makes the mining legacy sediments in the Cotehele a good site to understand the dispersal and impacts of such sediment to rivers and estuaries. The metals Cu and Pb were the most explored metals in upstream mines. In terms of magnitude, the sediment deposits presented concentrations ranging between 38 to 140 times higher than background values for Cu and 2 to 16 times above background values for Pb. A bioaccumulation experiment exposing snails to re-suspended sediments in waters with different salinities was performed. The aim was to understand how different salinities can influence the uptake of metals. The bioaccumulation experiment demonstrated that the disturbance of sediments released metals at a concentration that may cause deleterious ecotoxicological effects. Modelling simulations demonstrated that the worst-case scenario would spread Cu concentrations above EQS (Environmental Quality Standards) in areas with high potential for bioaccumulation for a prolonged time. After agriculture, pollution from abandoned mines is the second main reason for the deterioration of the Lower Tamar. The results demonstrated that the impacts of climate change could bring further challenges to the improvement of the Lower Tamar water quality.

Full textAbstract:
The main aim of this research is to investigate occupants’ thermal comfort and energy performance of multi-storey residential buildings in one of the major cities in Libya (Darnah). The work was implemented in stages as follows: 1. Gathering and analysing real weather data from a number of locations in Libya. 2. Gathering and analysing building data from residential multi-storey blocks in Darnah. 3. Conducting preliminary computer analyses using the above information to get a better idea about thermal conditions inside multi-storey block flats in Darnah. 4. Visiting Darnah and collecting real data using specifically designed survey or questionnaire forms to understand and assess how people feel while living inside their flats. 5. Analysing the computer results and field data and trying to come up with solutions to improve existing multi-storey blocks in terms of indoor climate and energy consumption and introducing guidelines for designers of new buildings in Libya. The subjective data was collected and tabulated by using a questionnaire, which has been widely used and shown to be effective, to determine people's responds through questions modified especially for the comfort purpose. Questionnaires were collected from households of 12 buildings: involving a total of 337 flats. The questionnaires compare the significance of the thermal sensation, the thermal comfort, and the building design. The results show that the thermal comfort is not satisfied, unless modified, and improving take place in these case study buildings. Thus a modification is proposed, the results from the present study show also that the insulation material is essential in this type of climate and can help to reduce up to 63% of heat gain and a reduction of 6 degrees of indoor temperature. Results also indicate that the construction of residential dwellings using existing materials is less conducive to the climatic conditions of hot dry climates and not suitable for the occupants’ requirements of comfort. Human thermal comfort was assessed using the adaptive model, to show that the climate and building’s envelope have a significant impact on human comfort perception and indoor environment. This research is mainly aimed at "explaining" the trends in the energy flows within buildings under the climatic conditions of Mediterranean zones and to establish a comfort zone for occupants within this type of climate. The results should help in the formulation of design guidelines for use in the process of building design by builders, architects and engineers. Also this research is in line with the Libyan’s government aim to make better use of renewable energy sources such as the sun for keeping buildings comfortable for their occupants.

Full textAbstract:
This final project is made as a Minor Field Study in Dar es Salaam, Tanzania. Tanzania is one of the poorest countries in the world and this is reflected in the way they live. Many people live in simple houses made out of mud, but the house that have been studied for this final project are a luxurious house from a Tanzanian perspective. The company that builds these houses are National Housing Corporation and it is this company that have provided drawings, information and educational visits. The purpose of this project is to gain knowledge about how a Tanzanian twostorey family house is constructed and designed. The aim is to evaluate if Swedish knowledge in building technique can be implemented to a Tanzanian two-storey family house concerning the climate, building structure and eco friendly construction. To be able to carry through with this final project a Minor Field Study has been executed in Dar es Salaam, Tanzania. During the field study educational visits, interviews and own observations has been made. By studying the drawings, read the interviews and look at photographs that were taken at the site several conclusions have been made. The foundation is the thing that differ the most from a Swedish villa. The slab is cast on underground walls and has only a mould around. Since it does not have a mould underneath the concrete can mix with the limestones and the drainage function is destroyed. The concrete strip that is placed underneath the underground walls has a damp proof membrane underneath which should be placed over the entire foundation structure. The roof is constructed by trusses and rafters in small dimensions. The dimensions could be increased to enlarge the distance between them. The windows are equipped with grilles that should protect from break-ins but also makes it harder to get out in case of fire. The upper slab is merged with the balconies and the balconies do not have an inclination out from the house. This could cause damages on the structure if water is stored there. The walls are made out of concrete which is the best material concerning the climate. To get an even better indoor climate the walls and the rest of the structure could be isolated so energy can be saved when the air conditioner is used. Tanzanian do not think in an eco friendly way but in this question a lot of improvements could be made. From a Swedish perspective there are a lot of things that can be improved on the studied house to get a more sustainable house concerning the structure, climate and eco friendly.Detta examensarbete har gjorts som en Minor Field Study i Dar es Salaam, Tanzania. Tanzania är ett av de fattigaste länderna i världen och detta återspeglas i deras sätt att bo. Många människor bor i enkla hus gjorda av lera men huset som har studerats för detta examensarbete är ett lyxigt hus sätt ur ett tanzaniskt perspektiv. Företaget som bygger dessa hus är National Housing Corporation och är det bolag som har lämnat ritningar, information och ordnat studiebesök. Syftet med detta projekt är att få kunskap om hur en tanzanisk tvåvåningsvilla byggs och utformas. Målet är att utvärdera om svenska kunskaper i byggnadsteknik kan implementeras på en tanzanisk tvåvåningsvilla med hänseende till konstruktionen, klimatet och miljövänlig konstruktion. För att kunna genomföra detta examensarbete har en Minor Field Study gjorts i Dar es Salaam, Tanzania. Under fältstudien har studiebesök, intervjuer och egna observationer gjorts. Genom att studera ritningar, läsa gjorda intervjuer och titta på fotografier som togs på plats har flera slutsatser gjorts. Grundkonstruktionen är det som skiljer sig mest från en svensk villa. Plattan är gjuten på underjordiska väggar och har bara en gjutform runt om. Eftersom det inte finns någon form under kan betongen blandas med kalkstenen och dräneringsfunktionen kan då förstöras. Betongdelen som är placerad under de underjordiska väggarna har en fuktspärr som också borde placeras över resten av grundkonstruktionen. Taket är konstruerat av takstolar och takbjälkar i små dimensioner. De små dimensionerna resulterar i att takstolarna och takbjälkarna måste sitta tätare än om de skulle ha haft större dimensioner. Fönstren är försedda med galler som ska skydda från inbrott, men de gör det också svårare att komma ut i händelse av brand. Det övre bjälklaget är hopgjutet med balkongerna och balkongerna har inte någon lutning ut från huset. Detta kan orsaka skador på konstruktionen om vatten samlas där. Väggarna är gjorda av betong som är det bästa materialet ur klimatsynpunkt. För att få ännu bättre inomhusklimat kan väggarna och resten av konstruktionen isoleras mot värmen så att energi kan sparas när luftkonditioneringen används. Tanzanier tänker inte på ett miljövänligt sätt, och därför finns det en hel del förbättringar att göra på det här området. Ur ett svenskt perspektiv finns det mycket som kan förbättras på det studerade huset för att få ett mer hållbart hus med hänseende till konstruktionen, klimatet och miljövänlig konstruktion.

The use of grain aeration as a tool to minimize post-harvest losses requires lower ambient temperature (≤ 20°C) and relative humidity (≤ 70%) conditions than what is usually available during the summer season in temperate climates and throughout the year in some tropical climate regions. Warm and moist conditions contribute to pest problems and increase dependence on chemical control for pest reduction as part of grain management strategies. The grain chilling technology is a non-chemical alternative to cool grain stored under high risk climatic conditions. For this research project, the grain chilling technology was tested in a 1,350-ton low moisture content wheat silo during the 2015 and 2016 summer harvests in Kansas. The grain temperature was lowered from a maximum of 39°C to a minimum of 17°C in less than 250 hours. The results showed that chilled grain maintained at temperatures under 20°C reduced the development rate of insect pests compared to grain stored at temperatures over 25°C and cooled with ambient aeration. However, the cost of grain chilling was calculated to be between 0.26 and 0.32 $/t higher than using ambient aeration. Through computer simulation it was possible to evaluate the performance of the grain chiller against four different ambient aeration strategies for paddy rice stored under the tropical climatic conditions of the North Pacific coast of Costa Rica. After six months of storage, the minimum grain temperature achieved through ambient aeration was 30.8°C using an aeration strategy based on a grain-ambient temperature differential greater than 10°C. Grain chilling lowered the average grain temperature from 35°C to below 15°C in 117 hours and the maximum average temperature it registered after six months of storage was 15.5°C. The economic evaluation of the simulated ambient aeration and chilling strategy determined that the operational costs of grain chilling were between 2 and 4 $/t lower than ambient aeration plus fumigation. However, the initial cost of the grain chiller made the net present cost (NPC) of the chilling strategy between 0.22 and 0.85 $/t higher than the cost of ambient aeration plus fumigation over a 10-year analysis. Several potential financial options were analyzed to make the grain chiller more economically feasible for a rice miller in Costa Rica. It was concluded that the grain chilling technology can reduce grain temperatures below 20°C in a relatively short period of time, which helps control insect populations and maintain grain quality during summer storage in temperate climates and in tropical climates. Utilizing grain chilling reduced operational costs between 78% and 88% when compared to using chemical control of pests. Additionally, it was determined that an initial cost of $74,700 for the grain chiller would require a 16% discount or at least 10,641 t to be chilled annually to make this technology viable for the Costa Rican rice milling industry. Leasing the grain chiller (ten equal payments of $10,926) or adding a premium sell price of 1 $/t to chilled rice would make this technology feasible compared to the traditional grain management strategies utilized in Costa Rica.

Full textAbstract:
Packaging for food products has impacts on the environment. In particular, single-use packaging have been criticized for the environmental and social impact created along recycling supply-chains in Asia. As a result, reusable packaging for food products started to reappear in Europe. This paper evaluates the environmental impacts of reusable packaging for Unwrapped’s business model using the organisational lifecycle assessment framework. The overall impacts of the organisation and hotspots of reusable packa ging are identified and compared with a reference retail activity using single-use packaging. The upstream processes of production of food products resulted in being the most significant impacts. However, reusable packaging performed worse and better than single-use packaging depending on the number of uses. The identified improvements for reusable packaging materials are proposed by increasing the number of uses. Changes in the upstream mode of transportation are other adopted improvement options for Unwra pped’s business model. The organisational lifecycle assessment framework highlighted issues in the current supply chain system that affect the niche business model in achieving the positive environmental benefits of reusable packaging. However, the reusable packaging business model shows promising aspects in a move towards sustainable businesses.Matförpackningar påverkar miljön. Särskilt blev engångsförpackningar kritiserad för dessa miljö och sociala påverkan i återvinningsbranschen i Asien. och möjligheter.

Den här avhandlingen kommer att granska och diskutera användning av återvinningsbara förpackningar i Unwrappeds affärsmodell med hjälp av organisationens livscykelanalys. Unwrappeds miljöpåverkan fastställs och jämförs med liknande affärsmodeller för engångsförpackning. Matproduktion innan förpackningen har den mest betydande påverkan. Återvinningsbara förpackningar visade sig vara bättre eller sämre beroende på antal gånger dem används. De fastställda förbättringarna för återanvändbara förpackningsmaterial är att återanvända dem så många gånger som möjligt. Förändringar i transportering är en annan förbättringsalternativ för Unwrappeds affärsmodell.

Full textAbstract:
The work in this thesis examines the land utilisation and simulated thermal performance of a pair of two-storey, three bedroom, semi-detached earth sheltered houses based on an existing residential development in South Wales, UK. When designed as Exposed South Wall type earth sheltered houses, which incorporate a number of passive solar design principles, each house provides a ratio of 0.508 for the internal floor area to the overall plot area, which is more efficient than 0.319 for a non earth sheltered house on the same development site. The simulation study has shown that the temperature of the earth sheltering the ground floor rooms is relatively stable on the coldest and warmest day of the CIBSE test year of 1985, but fluctuates widely on the same days at 1500 mm below ground level. The stable earth temperatures enable the ground floor rooms in twenty computer models to record higher resultant temperatures than the first floor rooms, on both the above days. In addition, the temperature range between models in the ground floor rooms is much smaller than in the first floor rooms where there are three variations of earth cover of 1500, 750 and 250 mm. With 100 mm of externally placed polystyrene insulation and an exposed, insulated and south facing first floor wall, 1500 mm of earth sheltering and family occupancy is required, so that both the ground and first floor rooms record resultant temperatures between 18 and 21 °C. With an insulated first floor buffer wall and Trombe wall or a non-insulated first floor buffer wall and insulated passive solar conservatory higher resultant temperatures are recorded and thinner earth covers become feasible with family occupancy. By increasing the insulation to 300 mm of polystyrene the thickness of earth cover and the inclusion of a first floor passive solar collector becomes less significant in recording comfortable internal resultant temperatures. However, the internal resultant temperatures exceed the upper comfort temperature of 23 °C in most rooms in the family and single adult occupied earth sheltered houses. Three optimum design solutions are given which record comfortable internal temperatures and that provide designers with a choice of earth cover, first floor design configuration and insulation thickness.

Full textAbstract:
Global climate change is predicted to affect timing and severity of disturbance events (e.g., fire, drought, hurricanes, wind storms, and inundation), but the extent of these disturbance events and their impacts on natural ecosystems may vary regionally. Rising sea level, increased frequency and intensity of tropical storms, and altered inundation regimes are likely to create changing environmental conditions in low-lying coastal ecosystems. These large scale disturbances may increase resource availability and regeneration spaces, reduce competition, and possibly increase community vulnerability to invasion. Shifting disturbance regimes and invasion together are predicted to drive long-term shifts in coastal plant community structure and ecosystem processes. However, impacts of altered environmental conditions on native and invasive plant species and the species responses to changed environmental conditions are poorly understood. The aims of this study were: (i) to assess the probability of occurrence of juveniles of the invasive exotic Triadica sebifera and co-occurring native species, Baccharis halimifolia, Ilex vomitoria, and Morella cerifera in the field in relation to surrounding environmental factors, (ii) to assess the effects of elevated salinity across a typical coastal transition on germination of T. sebifera, B. halimifolia and M. cerifera, using controlled growth chamber and greenhouse experiments, (iii) to assess the effects of climate change and shifting inundation and tropical storms regimes on T. sebifera, B. halimifolia and M. cerifera, and (iv) to evaluate the role of vesicular arbuscular mycorrhizae (VAM) on spread of invasive T. sebifera in coastal transition ecosystems at the Grand Bay National Estuarine Research Reserve (GBNERR), Coastal Mississippi, southeastern USA. Results from assessing the probability of occurrence of juveniles of invasive and co-occurring native species showed that soil water conductivity (i.e., salinity) was the major factor related to the occurrence of invasive T. sebifera and native B. halimifolia, I. vomitoria and M. cerifera along the coastal transitions. Probability of occurrence of the invasive T. sebifera was significantly related to landscape factors and occurrence was highest in close proximity to roads, trails, power lines, and recreational sites, and water bodies. These results imply that future increases in salinity will negatively impact I. vomitoria, M. cerifera, and T. sebifera, leading to range contraction of these species away from the coast. However, natural and anthropogenic disturbances that often increase resource pulses and reduce competition, likely increase the dominance of T. sebifera in already invaded areas. Positive effects of landscape structures on T. sebifera occupancy highlight the role of landscape variables in promoting new invasions in coastal forests of the southeastern USA. Controlled growth chamber and greenhouse germination experiments demonstrated that germination of all species (i.e., T. sebifera, B. halimifolia, and M. cerifera) decreased with elevated salinity and that the reduction was most pronounced in soils from the most seaward zones along the coastal transition. Although native B. halimifolia was least sensitive to elevated salinity, invasive T. sebifera displayed plasticity of germination trait across different salinity levels in most inland soils. These results suggest that the phenotypic plasticity may facilitate spread of Triadica sebifera under some degree of salinity stress in more inland section of the coastal transition. A manipulative greenhouse experiment demonstrated that simulated canopy damage from intense hurricane winds and associated storm surge produced differential effects on survival and growth of native (B. halimifolia and M. cerifera) and invasive (T. sebifera) species at simulated different forest conditions common in the GBNERR. Invasive T. sebifera was by far the most shade tolerant of the three species and seedling survival under highly shaded conditions may provide it with a competitive edge over native species during community reassembly following tropical storms. T. sebifera may better utilize post-hurricane conditions (e.g., resource-rich empty spaces) and potentially increase its dominance in coastal forested ecosystems. The last experimental study revealed that invasive T. sebifera had higher VAM colonization compared to co-occurring native species both in controlled greenhouse and field experiments, and that the higher colonization leads to significant increases in aboveground biomass, supporting the hypothesis that VAM fungi strongly benefit the invasive species. These results suggest that the VAM colonization may be necessary for the initial establishment of T. sebifera along the coastal transitions. Furthermore, my research also suggested that T. sebifera was not allelopathic and did not interfere with growth of native species. Overall, the findings of this research provide insight into the impacts of climate change related shifts on performance of invasive and co-occurring native species across coastal transitions of the southeastern USA. Variation in invasive and co-occurring native species' performances under changed environmental conditions (e.g., elevated salinity and increased light availability) and improved mutualistic association between invasive T. sebifera and VAM fungi may drive increased invasion with frequent community reassembly of low-lying coastal ecosystems undergoing rapid climate change.

Full textAbstract:
Bien qu'appartenant à la zone « tempérée », la France et les îles Britanniques connaissent pourtant de nombreux excès climatiques. Parmi ceux-ci, les tempêtes hivernales font partie des aléas les plus destructeurs, en même temps qu'elles assurent un transfert d'énergie thermique de la zone tropicale vers les plus hautes latitudes. Pour mieux comprendre la climatologie de ce météore, une chronologie des tempêtes a été établie à partir des cartes des bulletins météorologiques quotidiens disponibles depuis la fin de l'année 1864. Plus de 2400 cas ont été identifiés, ce qui a permis d'évaluer la variabilité interannuelle et intra-annuelle de l'aléa. Les données de pression recueillies sur les cartes et leur analyse mettent en évidence le creusement des tempêtes au cours de la période. Les directions de vent figurées sur les cartes ont par ailleurs permis de réaliser des roses des vents pour une série de stations irlandaises, britanniques et françaises. La cartographie des minima de pression permet de faire apparaître des trajectoires privilégiées. L'étude climatologique s'achève par la recherche d'une cyclicité des tempêtes et par l'étude de leur lien avec l'ONA. Ce travail s'intéresse ensuite aux tempêtes qui ont fait événement pour les météorologues et/ou pour l'ensemble de la société du pays concerné. Ainsi sont mises en lumière les étapes de la compréhension de la météorologie des tempêtes. D'autre part, les tempêtes-événements retenues illustrent des évolutions économiques et sociales ainsi que les changements de gestion du risque tempête. Elles montrent aussi comment la culture du risque tempête s'est forgée et comment la mémoire du risque a parfois été réactivéeThrough France and the British Isles belong to the « temperate » zone, they both experience a lot of weather hazards. Among those hazards, winter storms are some of the most destructive ones, but in the same time they contribute to the thermal energy transfer from the tropical zone to the mid-latitudes. As a result, they play a major role in the world's thermal balance. In order to better understand the climatology of these meteors, a storm chronology has been established from the daily weather maps that are available since the end of 1864. More than 2400 cases have been identified which has allowed to measure the year-to-year and seasonal variability. Pressure data collected from the maps and their analysis show a deepening trend of their core pressures over the period. Wind directions displayed on the maps for different weather stations have been used to generate wind roses for a selection of Irish, British and French weather stations. The climatological study ends up in the calculation of the periodicity of storms as well as their link with the NAO. This study focuses then on a few storms that have been considered has events, either for the meteorologists or for the entire population of the country hit by the storm. Thus is highlighted the different stages of the meteorological understanding of wind storms in Europe. Moreover, the selected storms as social events underline economic and social evolutions as well as changes in the risk management of storms. These storms also show how a risk culture has emerged and how the risk memory has been re-activated

Full textAbstract:
The phenomenon of climate change exists in a liminal state between denial and acceptance, past and future, theory and reality, problem and catastrophe, unfolding in the spaces between apparently stable forms. This thesis considers different temporalities emerging within this transition through a creative exploration of extreme weather and climatic events that seeks to foreground the idea of change itself. Research centers around the Florida Keys, a low lying archipelago that is widely expected to become uninhabitable in the next half century due to sea level rise, but only if the islands do not suffer a similar fate much sooner with the sudden arrival of a catastrophic hurricane. While most Keys residents are unconcerned about the growing reality of sea level rise, hurricanes are a constant threat generating a palpable atmosphere of anticipation and corresponding precaution. In resonance with this regular storm activity in the Florida Keys, the project also reflects on the coincidental occurrence of Hurricanes Irene (2011) and Sandy (2012), two errant and devastating storms that visited the northeastern United States over the course of this project and personally affected the author. Thus, extreme weather provides a material entry point into the complex and far-reaching event of climate change, offering an opportunity to theorize transition and to reflect on what might be creatively recuperated from cross currents of climate and catastrophe. In conclusion, the thesis proposes an ontology inspired by the unique reproductive strategy of the mangrove plant that has thickly and extensively colonized the coastline of southern Florida and through which events are understood to possess qualities of latency, accrual and distribution and to give rise to a future that is germinal, a present that is continuously resignified and a past that remains profoundly creative.

Full textAbstract:
Almost one-half of the annual precipitation in the southwestern United States occurs during the North American monsoon (NAM). Given favorable synoptic-scale conditions, organized monsoon thunderstorms may affect relatively large geographic areas. Through an objective analysis of atmospheric reanalysis and observational data, the dominant synoptic patterns associated with NAM extreme events are determined for the period from 1993 to 2010. Thermodynamically favorable extreme-weather-event days are selected on the basis of atmospheric instability and precipitable water vapor from Tucson, Arizona, rawinsonde data. The atmospheric circulation patterns at 500 hPa associated with the extreme events are objectively characterized using principal component analysis. The first two dominant modes of 500-hPa geopotential-height anomalies of the severe-weather-event days correspond to type-I and type-II severe-weather-event patterns previously subjectively identified by Maddox et al. These patterns reflect a positioning of the monsoon ridge to the north and east or north and west, respectively, from its position in the "Four Corners" region during the period of the climatological maximum of monsoon precipitation from mid-July to mid-August. An hourly radar gauge precipitation product shows evidence of organized, westward-propagating convection in Arizona during the type-I and type-II severe weather events. This new methodological approach for objectively identifying severe weather events may be easily adapted to inform operational forecasting or analysis of gridded climate data.

Full textAbstract:
This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse. The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night. The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse. It also shows that heat is stored in the concrete wall and during the night the wall temperature is higher than both the outdoor temperature and the greenhouse temperature. This makes the wall a source of heat during this time.Växthus är pga. sin utformning väldigt känsligt för klimatets påverkan. Detta resulterar i att klimatet i växthuset under soliga dagar kan uppnå väldigt höga temperaturer medans temperaturen under kalla dagar och nätter kan bli lika låg som den rådande utomhustemperaturen. Växthusets klimat blir därför väldigt extremt och temperatursvängningarna stora. Temperatursvängningarna beror till stor del på växthusets låga värmetröghet och genom att öka trögheten i en byggnad kan temperatur svängningar minskas och ett jämnare termisk klimat uppnås. En ökning av trögheten kan också bidra till att värme lagras under varmare perioder och på så sätt minska ett eventuellt uppvärmningsbehov under de kalla perioderna. För att undersöka tröghetens inverkan och möjligheterna till värmelagring hos ett växthus har detta examensarbete inriktats på uppbyggnaden av en datormodell som kan simulera ett växthus termiska förhållanden. Modellen har sedan använts för att undersöka hur en betongvägg påverkar det termiska klimatet i växthuset samt betongväggens förmåga att lagra värme. Datormodellen har byggts upp i MATLAB vilket gör det möjligt att med klimatdata från olika perioder simulera växthuset inre klimat. Datormodellen bygger på matematiska beräkningar som grundar sig på fysikaliska och termiska samband. Växthuset som undersöks i datormodellen bygger på ett växthus som är planerat att uppföras på trädgårdsanläggningen Wij trädgårdar i Ockelbo. Växthuset går under namnet Eldtemplet och ingår i projektet ”Ny energi i gamla landskap” som ska utforska möjligheterna till nya energikällor inom trädgårds- och odlingsverksamhet. Simuleringar har genomförts med klimatdata från ett dygn under tre olika årstider, vinter, vår och sommar. Resultatet från simuleringarna visar att temperaturerna i växthuset påverkas väldigt mycket av den infallande solstrålningen. Införandet av en betongvägg ökar växthusets tröghet och jämnar ut temperatursvängningarna i växthuset. Simuleringarna visar också att betongväggen får en värmelagrande förmåga och under vissa perioder kan tillföra växthuset värme under natten då temperaturen i växthuset sjunker. Genom resultatet kan slutsatsen dras att det finns åtgärder att ta till som kan förbättra växthusets termiska egenskaper väsentligt och göra växthus mer energieffektiva.

Full textAbstract:
Four continuous high-resolution peat records for the Holocene have been reconstructed across a ~300km transect from Shebster in Caithness to Yell in the Shetland Isles. These records describe the nature and extent of North Atlantic climate changes inferred from indicators of storminess and minerogenic aeolian dust, and are supported by radiogenic isotope analysis, tephrochronology and radiocarbon dating. The environmental changes at all four sites displays a significant degree of synchrony in response to changes in the position of the polar front jet (PFJ) stream and the phase of the North Atlantic Oscillation (NAO). Bromine concentrations in the peat, derived from sea spray, are used to reconstruct storm frequency and storm intensity, and mire surface wetness is used as an indicator of longer-term climate shifts. The results suggest a strong link between positive phases of the NAO and storminess. Subtle differences between the bromine concentrations and the mire surface wetness suggest that high intensity but perhaps less frequent periods of storminess are not necessarily associated with a wetter climate. Atmospheric minerogenic dust concentrations are used to reconstruct large-scale climate changes across the wider North Atlantic region. The results suggest a sympathy between dust activity and periods of glacial advance and a negative index of the NAO. Radiogenic isotope analysis suggests that the smallest particles may originate from Iceland.

Full textAbstract:
Le Dolomiti rappresentano il margine più meridionale della catena Alpina orientale. Nelle alte valli dolomitiche la caratterizzazione cronologica e spaziale delle fluttuazioni glaciali precedenti l’Olocene rimane ancora oggi poco documentata, nonostante le molteplici possibilità di indagine offerte dallo sviluppo di nuove tecniche di datazione assoluta e alla recente possibilità di integrare le indagini sul terreno con l’analisi di immagini telerilevate ad alta risoluzione. Il presente lavoro illustra nuovi dati che permettono la ricostruzione paleo-geografica e paleo-ambientale del Tardo Pleistocene – periodo caratterizzato da variazioni climatiche millenarie e sub-millenarie a scala globale – di un’area delle Dolomiti Orientali, l’Alta Val Badia. Qui, nonostante l’intensa dinamica di versante, sono stati identificati mappati depositi glaciali ancora ben preservati e attribuiti, sulla base delle evidenze geomorfologiche, all’Ultimo Massimo Glaciale (UMG) e al Tardoglaciale. La presente ricerca si è avvalsa dello studio di questi depositi per ricostruire l’estensione e i volumi dell’ice field che durante l’UMG occupava la valle e le fasi di avanzata dei ghiacciai locali durante il Tardoglaciale. La datazione di questi depositi mediante la tecnica delle superfici esposte (36Cl Surface Exposure Dating), applicata per la prima volta in Alta Badia e valli limitrofe, è risultata fondamentale per vincolare temporalmente e spazialmente le fluttuazioni dei paleo-ghiacciai della valle. Le geometrie dei ghiacciai (estensioni areali, paleotopografie, volumi) sono state ricostruite sulla base dell’analisi di fotografie aeree e Modelli Digitali del Terreno, di rilievi geomorfologici e della gestione ed elaborazione di dati tramite Sistemi Informativi Geografici. Le stime delle Linee di Equilibrio tardoglaciali, relative a diverse fasi di avanzata, sono state calcolate per ogni singolo ghiacciaio, fornendo così l’opportunità di effettuare correlazioni paleoclimatiche su scala regionale per il periodo considerato. Le evidenze geomorfologiche e le età di esposizione superficiale hanno permesso di vincolare l’età minima del ritiro dell’ice field in corrispondenza dell’UGM, intorno a ca. 18-17 ka. Inoltre sono state riconosciute diverse fasi di riavanzata tardoglaciale occorse tra 16 e 12 ka, permettendo così di ampliare il dataset cronologico alpino per il periodo che si estende dall’UGM fino alla fine del Tardoglaciale.
La ricerca si è avvalsa inoltre dello studio di depositi sub-superficiali portati alla luce grazie a carotaggi effettuati a 2000 metri di quota sull’altopiano del Pralongià, coperto dall’ice field durante l’UMG. Datazioni radiometriche su materiale organico, prelevato dai carotaggi a diverse profondità, hanno fornito età comprese tra 45 e 38 ka (MIS 3), uniche nel quadro delle ricostruzioni paleo-geografiche e paleo-climatiche alle alte quote alpine. Lo studio di questi depositi ha permesso di concludere che durante il MIS 3 il Pralongià era libero dai ghiacci. Dal punto di vista paleo-climatico è confermata la difficoltà, durante questo periodo, di una persistenza del ghiaccio al suolo, che qui in Val Badia, vista la peculiare conformazione orografica, è stata probabilmente ancor più amplificata. Lo studio ha inoltre rivelato che tra 38 ka e l’instaurarsi delle condizioni pleniglaciali (~27 ka) depositi clastici gravitativi, provenienti dai massicci dolomitici che orlano la valle, sono stati messi in posto sull’altopiano. Questa interpretazione trova riscontro in analoghi esempi di grandi frane occorse durante e dopo l’UMG nelle Alpi italiane riportate dalla letteratura.The Dolomites constitute the southernmost margin of the Eastern Alps. In the high Dolomites catchments, the chronological and spatial characterization of glacial fluctuations occurred during the Late Pleistocene remains still today not well constrained; this despite the recent improvement in investigation methods offered by the development of new dating techniques and by the current possibility to integrate field surveys with high resolution remote sensing data. The present work illustrates new data that allow the reconstruction of paleogeographic and paleo-environmental conditions occurred during the Late Pleistocene – a period characterized by global millennial and sub-millennial climate changes – in an area of the Eastern Dolomites, the Alta Badia valley. Despite the intense slope dynamics which characterize the valley, well preserved glacial deposits have been identified and mapped. They have been attributed, on the basis of geomorphological evidence, to the Last Glacial Maximum (LGM) and to the Lateglacial periods. The research took advantage of the study of these glacial deposits to reconstruct the extent and volumes of the ice field that during the LGM occupied the valley, as well as the advance phases of the local glaciers occurred during the Lateglacial. The dating of these deposits by means of the 36Cl Cosmic Ray Exposure (CRE) technique, applied for the first time in Alta Badia and neighbouring valleys, was fundamental to constrain in space and time paleo-glaciers fluctuations within the valley. The geometry of the glaciers (areal extensions, paleo-topography, volumes) were reconstructed by means of the analysis of aerial photographs and Digital Terrain Models, as well as through geomorphological field surveys and management and processing of data using Geographic Information Systems. The Lateglacial Equilibrium Line Altitudes (ELAs) were estimated in relation to different phases of glacial advance. The ELAs have been calculated for every single glacier, providing the opportunity to carry out paleoclimatic correlations on a regional scale for the period considered. The geomorphological evidence and the results of CRE dating on superficial deposits allowed to constrain the minimum age for the withdrawal of the LGM ice field that was at ca. 18-17 ka. In addition, several phases of glacial advance occurring between 16-12 ka were recognized. These results allowed to improve the Alpine chronological dataset relevant to the period ranging from the LGM to the end of the Lateglacial. The research took also advantage of the study of subsurface deposits exposed owing to eight continuous coring boreholes and an excavation wall on a former glaciated plateau, Pralongià, at ca. 2000 m a.s.l. Radiocarbon dating performed on organic sediment – collected from the boreholes and from the excavation wall at different depths – provided ages ranging between 45 and 38 ka BP (MIS 3), which are unique within the framework of the paleogeographic and paleoclimate reconstructions in high Alpine catchments. Stratigraphic evidence and radiocarbon dating results allowed to conclude that the Pralongià plateau was ice free during most of the MIS 3. From a paleoclimatic viewpoint, it is then confirmed the difficulty, during MIS 3, of ground ice persistence, which was probably even more amplified by the peculiar orographic conditions of the Alta Badia valley. The study revealed also that between 38 ka and the onset of full glacial conditions (~ 27 ka) gravitational clastic deposits, originating from the Dolomites massifs surrounding the valley, were emplaced on the plateau. This interpretation is supported by many examples of large landslides that occurred during and after the LGM in the Italian Alps which are reported in literature.

Full textAbstract:
Les études sur les personnages féminins stendhaliens et mériméens sont certainement nombreuses. Toutefois, notre travail envisage une nouvelle approche qui a pour objectif de mettre en évidence les rapports que Stendhal et Mérimée entretiennent avec les théories qui prédominent dès le XVIIIe siècle. Nous nous référons en particulier à la théorie des quatre tempéraments et la théorie des climats et leur influence sur la création des figures féminines, protagonistes des histoires qui constituent le corpus des Chroniques italiennes et des nouvelles de Mérimée, c’est-à-dire La Vénus d’Ille, Colomba et Carmen. Notre propos est de découvrir un nouvel aspect de la problématique féminine en analysant le type humain de la femme du Midi étudié sous la perspective de l’influence des théories susmentionnées. Nous avons également mis en relation la forme littéraire adoptée par les deux écrivains (la nouvelle, le petit roman) avec les sujets qu’ils abordent et l’effet qu’ils veulent produire sur le lecteur. En quoi, en effet, la forme brève qu'ils choisissent contribue-t-elle à l'effet de violence que la représentation du Sud est supposée produire ? Le récit court sert, à l'évidence, l'efficacité d'un propos à la fois esthétique, ethnologique et éthique. L’étude s’articule en trois temps. Dans un premier temps, nous nous intéressons à l’évolution de la théorie des tempéraments et la théorie des climats, ensuite, au contexte historique et culturel de la période à cheval entre le XVIIIe et XIXe siècles qui influence aussi la création littéraire de Stendhal et de Mérimée. Dans un deuxième temps, nous nous occupons de la poétique stendhalienne et mériméenne par rapport aux récits courts. Enfin, nous analysons les figures féminines par rapport aux études préliminaires que nous avons faites dans les parties précédentesStudies about female characters in Stendhal’s and Mérimée’s works are in no doubt numerous. However, the aim of our work is to highlight the relationship between these authors and the theories that prevailed from the eighteenth century onwards. We refer in particular to both the four temperaments theory and the climate the theory and their influence on the creation of female characters, protagonists in the stories we chose for our corpus: the Chroniques italiennes of Stendhal and the shorts stories La Vénus d’Ille, Colomba and Carmen of Mérimée. Our purpose is to unveil a new aspect of the female problematic by analysing Southern Europe woman human type observed from the perspective of the influence of the above-mentioned theories. We also linked the form chosen by the two writers (short story, little novel) with the themes they address and the effect they want to produce on the reader. To which extent is the short story type contributing to the effect of violence supposed to be produced by the depiction of the South? Short stories serve the efficiency of a purpose at the same time aesthetic, ethnological and ethical. This study consists of three parts. First of all, we examine the the evolution of both four temperaments theory and climate theory, as well as the eighteenth, beginning of the nineteenth century historical and cultural background which also influences Stendhal and Mérimée literary creation. Secondly, we reflect upon Stendhal’s and Mérimée’s poetics in relation to short stories. Finally, we analyse the female characters in relation to the preliminary studies previously mentioned
Gli studi sui personaggi femminili di Stendhal e Mérimée sono sicuramenti numerosi. Ciò nonostante, il nostro lavoro prevede un nuovo approccio che ha come obiettivo di mettere in evidenza l’influenza che le correnti di pensiero, che predominano a partire dal diciottesimo secolo, hanno sulla produzione letterario di Stendhal e Mérimée. In particolare, ci riferiamo alla teoria dei quattro temperamenti e alla teoria dei climi rispetto alla creazione dei personaggi femminili, protagonisti delle storie che costituiscono il corpus delle Cronache italiane e delle novelle di Mérimée, ossia La Venere d’Ille, Colomba et Carmen. Il nostro scopo è quello di mettere in luce un nuovo aspetto della problematica femminile, analizzando il tipo umano della donna meridionale studiato sotto la prospettiva delle teorie sopra menzionate. Abbiamo anche messo in relazione la forma letteraria adottata dai due scrittori (la novella, il piccolo romanzo) con l’argomento che trattano e l’effetto che vogliono produrre sul lettore. Concretamente, in che modo la forma breve che scelgono contribuisce all’effetto di violenza che la rappresentazione del Sud è presupposta produrre? La novella serve a rendere efficace un pensiero estetico, etnologico et etico. Lo studio si divide in tre parti. In un primo momento, ci interessiamo all’evoluzione della teoria dei temperamenti e alla teoria dei climi, in seguito, al contesto storico-culturale del periodo a cavallo tra diciottesimo e diciannovesimo secolo che influenza anche la creazione letteraria di Stendhal et Mérimée. In un secondo momento, ci occupiamo della poetica di Stendhal et Mérimée rispetto alla novella. Infine, analizziamo i personaggi femminili in rapporto agli studi preliminari effettuati nelle parti precedenti della nostra tesi

In the present thesis we focus on the two extremes of the wind speed – storms and atmospheric stilling – and analyse their impacts on lake environments and phytoplankton dynamics over short and long periods. As we realised the importance of the time scale in the context of our wind effect studies, we decided to have a closer look at other environmental data in the Lake Võrtsjärv database addressing the questions how the variability in environmental factors (thermal, wind, light- and water-level regimes) and phytoplankton variables is partitioned among different time scales from days to decades and whether matching shares can help to determine the leading factors responsible for phytoplankton dynamics.

This study discusses the potential of wine quality as a new proxy data for the historical climatology. Wine-growing regions represent traditional areas of research since the beginnings of the discipline, when it was discovered the value of grape harvest dates (GHD) for the reconstruction of temperatures in the pre-instrumental period. However, annual meteorological variability exerts a considerable influence also on winemaking’s results. To define the quality of wine we propose a quantitative index to convert narrative descriptions in vintage quality ratings. The analysis of the relationship between grape harvest dates and wine quality ratings shows significative correspondences in several European regions opening new perspectives of research for areas devoid of phenological data. Moreover, the information on vintages characteristics expands the meteorological knowledge available through the GHD series allowing useful suggestions about the seasonal distribution of temperature anomalies and precipitations. Finally, it was investigated also the role of the vintages quality in the economies of wine-growing regions, finding unexpected similarities in wine prices’ historical trends of different European countries.

Full textAbstract:
Physical disturbance in the form of storm events has been implicated as a major determinant of community structure in streams. But there has been limited study of this effect on individual taxa within the communities. Such work is needed because of untested assumptions regarding the behavior of bioindicator species in these systems. Development of intricate indices of insect tolerances to organic pollution have become commonplace in environmental monitoring. However, research on the effects of natural disturbance on biological water quality assessment is lacking. Hydropsychid caddisflies are relatively intolerant to organic pollution and the United States Environmental Protection Agency has outlined the use of these organisms and others as an indication of clean water. If a species is recorded as absent from samples when it is present but hidden, this false negative would bias the water quality assessment. I tested hypotheses regarding the behavior of hydropsychid caddisflies facing increased discharge, and the effect of stream size on the magnitude of this phenomenon.Three sites along the West Fork of the White River, Indiana USA were studied during nine storms between 2001 and 2004. Stratified sampling from the upper 15 cm of substrate prior to and just after a storm, and again following reestablishment of normal flow, revealed alterations of hydropsychid distributions. During storms all but one species sought refuge in the hyporheic zone at depths dependent upon storm intensity. The possibility that poor water quality resulting from increased discharge caused the hydropsychid behavior was refuted by chemical analysis. Family level biotic index (FBI) data demonstrated that increased discharge results in a reduction of stream FBI values. These results indicate that high intensity storm events influence biological monitoring and should be factored into sampling protocol.Department of Biology

Title: The role of marketing in the pursuit of sustainable consumption Level: Student thesis, final assignment for Bachelor Degree in Business Administration Authors: Emelie Johansson, Elin Lundin Supervisor: Zahra Ahmadi and Akmal Hyder Examiner: Agneta Sundström Date: 2020 – 06 Aim: The aim of the study is to examine the extent to which sustainable consumption is perceived and how sustainable marketing influences consumers' purchasing behavior and awareness. Method: In this study, we have used a quantitative method consisting of a survey. The survey was answered by a total of 223 respondents in order to test the study's hypotheses and purpose. Hypothesis testing was performed by descriptive analysis and correlation analysis using the SPSS program. The results obtained are reported in tables and analyzed in comparison with previous theory. Conclusion: The study has shown that consumers have a high level of awareness of sustainable consumption. However, sustainable consumption is not complied with to the same extent as the consumer is conscious, which is influenced by factors of price and habit. Studies have also shown that sustainable marketing has an effect on the consumer's buying behavior and awareness and that consumers demand more communication about this from the grocery stores. Contribution: The study has contributed to the supplementation of already existing research in sustainable consumption and sustainable marketing. We have been able to demonstrate a link between sustainable marketing and consumer sustainable consumption. The study's main benefits are showing how grocery stores can increase their understanding of their consumers and what sustainability issues motivates them in their efforts to promote sustainable consumption. Keywords: Sustainable marketing, sustainable consumption, environmental awareness, purchasing behavior, purchasing decisions, overconsumption, climate change, grocery stores, groceries.Titel: Marknadsföringens roll i strävan mot hållbar konsumtion Nivå: Examensarbete på Grundnivå (kandidatexamen) i ämnet företagsekonomi Författare: Emelie Johansson, Elin Lundin Handledare: Zahra Ahmadi och Akmal Hyder Examinator: Agneta Sundström Datum: 2020 – 06 Syfte: Syftet med studien är att undersöka i vilken utsträckning hållbar konsumtion uppfattas samt hur hållbar marknadsföring påverkar konsumenters köpbeteende och medvetenhet. Metod: I denna studie har vi använt en kvantitativ metod bestående av en enkätundersökning. Enkätundersökningen besvarades av totalt 223 respondenter i syfte att testa studiens hypoteser och syfte. Hypotesprövning utfördes genom deskriptiv analys och korrelationsanalys med hjälp av programmet SPSS. Resultaten som utvanns redovisas i tabeller och analyseras i jämförelse med tidigare teori. Slutsats: Studien har visat att konsumenter har en hög grad av medvetenhet om hållbar konsumtion. Däremot efterlevs inte hållbar konsumtion i samma utsträckning som konsumenten är medveten, vilket påverkas av faktorer såsom pris och vana. Studien har även visat att hållbar marknadsföring har effekt på konsumentens köpbeteende och medvetenhet och att konsumenterna efterfrågar mer kommunikation om detta från livsmedelsbutikerna. Uppsatsens bidrag: Studien har bidragit till komplettering av redan befintlig forskning inom hållbar konsumtion och hållbar marknadsföring. Genom att vi kunnat påvisa ett samband mellan hållbar marknadsföring och konsumenternas hållbara konsumtion. Studien ger främst nytta till livsmedelsbutiker för att öka förståelsen för dess konsumenter och vad som motiverar dem i arbetet med att främja hållbar konsumtion.

Ferwerda, SMA. "Blue ocean stories : climate colonialism and narrative disruption in Oceania." Thesis, 2022. https://eprints.utas.edu.au/46299/1/Ferwerda_whole_thesis.pdf.
Full textAbstract:
This dissertation argues that critical and creative attention to contemporary stories from Oceania opens up new ways to address the past, present and future effects of colonialism on changing oceanic environments. Colonialism is connected to climate change through issues that include rising sea levels, biodiversity loss, changing weather patterns such as floods and prolonged droughts, and ecological devastation. By examining literature, visual art and performance that go against canonical Western ways of reading the ocean, I foreground how we can unsettle climate colonialism and its effects on oceanic multispecies environments. I address how scholars of contemporary feminist materialisms and the environmental humanities can extend their study of water and the ocean to centre anticolonial perspectives via art, literature, and theory. Analysing anticolonial narrative disruption from an Oceanic perspective, this dissertation engages with work from Aboriginal, Indigenous, migrant and settler colonial scholars, writers and artists to show that the future can be oceanic and anticolonial.
The increased precarity of human-ocean relationships has been particularly visible in Oceania. Rising waters and environmental degradation do not affect all equally, nor are their causes evenly distributed. How we think about the colonial pasts of Oceania informs our imagination of oceanic futures. The effects of the mining industry, of nuclear testing, tourism, aquaculture, species extinctions, and the formation of the nation state, have had lasting consequences on oceanic spaces and how they are experienced and thought of in the present. From an anticolonial feminist materialist perspective, I aim to not only expand our ocean views but also to interrogate the perspectives that guide our gaze. I draw on research from the fields of Pacific and Ocean Studies to argue against a simplistic, oppositional and colonial relationship between human and ocean. Increasingly, but building on long legacies of oceanic thought, writers and artists from Oceania hold Western colonial discourse to account. By communicating oceanic realities in text, visual art and performance that offer alternatives to Western ways of reading the ocean, Oceanic art and literature unsettles the colonial afterlives apparent in contemporary human-ocean environments. I listen to and analyse published and publicly performed work — short stories, poetry, visual and performance art, and memoir — that redefines how we should think about the ocean in the twenty-first century.
This dissertation comprises two contextual chapters followed by four in-depth readings of the work of several artists and writers from Oceania. The first chapter addresses recent ‘blue turns’ in environmental and feminist theories to show how the implications of colonialism have remained largely underexamined or only analysed from a Western and Northern hemispherical perspective. Blue is a colour with a distinct colonial history. It appeals to the Western colonial imaginary and drew European ships across the seas to mine blue pigment from Afghan rocks and raise indigo plantations on stolen land, with stolen labour. How has this oceanic coloniality resurfaced in climate change times? Following Sylvia Wynter, Ursula Le Guin, Donna Haraway, Deborah Bird Rose and Thom van Dooren, I articulate storytelling as a foundation method to disrupt racialised power structures in settled and colonised areas of Oceania. The work of Aboriginal, Indigenous, settler and migrant writers and authors across Oceania informs my critique of the lingering coloniality of Western engagement with the seas and its associated imaginations. Mining, nuclearisation, militarisation, extinction, erasure, borders, and migration shape my discussion in four thematic chapters, which focus respectively on short stories by Gina Cole and Ellen van Neerven; poetry by Kathy Jetn̄il-Kijiner and Craig Santos Perez; installation and performance art by Lucienne Rickard and Mandy Quadrio; and Behrouz Boochani’s memoir No Friend but the Mountains. The ‘Blue Ocean Stories’ in this dissertation respond to the intersection of climate change, colonialism and the ocean, and take aim at the continued and reiterated coloniality of some Western oceanic imaginaries

The intent of this study was to investigate the efficient use of energy by developing an energy efficient grocery store combined with cogeneration. This study demonstrated the potential to reduce the energy use in buildings, by implementing a decentralized source of energy generation that allowed for the use of a portion of the energy generated to be shared across building boundaries.
This study considered a high energy use building such as a grocery store to be a part of a residential community, which could potentially participate in the sharing of energy across building boundaries. To better utilize energy resources the study proposed the implementation of a cogeneration facility to supply energy primarily to the store. Surplus energy generated by this cogeneration system was then shared with the requirements of the surrounding residential community. Finally, in order to better account for energy consumption of these buildings both site and source energy was considered. The study focused on hot and humid climates. This study was presented in two parts: Analyzing conventional grocery store systems to determine the maximum savings possible; and examining the option of co-generation systems to provide power to grocery stores and a portion of the community in order to reduce source energy use for the grocery store and a portion of the surrounding community.
Source energy savings were in the range of 47% to 54% depending on the energy efficiency measures selected and the cogeneration configuration determined in the grocery store. Economic payback periods in the range of 4 to 7 years (time until zero net present value) were observed. The selection of appropriate options was narrowed down to two options that utilized more thermal energy within the boundaries of the store and generated more amount of surplus energy to be absorbed by the neighboring residential buildings.

As climate change impacts a growing number of aspects of economic activity, it is becoming ever more vital to understand how these effects will manifest. This work advances the study of the impacts of environmental change. First, I provide a panel analysis at the country level that identifies the effects of dust storms on economic activity in West Africa. I also find some evidence in the agricultural sector to support the finding of damaging effects. Second, I examine the extent to which dust storms and climate shocks affect migration in the same region. While temperatures and precipitation are found to play important roles, dust storms do not appear to have a significant influence. Third, I consider the role of adaptation to climate change in the United States. I build a model that predicts the locations most likely to be used in agriculture in the future, allowing for better forecasting of shifts in the areas used for agricultural production.

Independent research into the traditional information encompassed a study of the traditional way of life of the D’harawal people, research into the climatic cycles outlined in the publication and a survey of both natural history illustrators and childrens book illustrators and the techniques and media they use. The illustrations rely on a study of natural history in order to provide informative, accurate and naturalistic representations of the plants, animals and environment. The illustrations form a ‘bridge’ between cultures by expressing Aboriginal culture using an art form that is easily interpreted by all Australians. The subsequent artworks were presented to the author to use as illustrations for this publication where appropriate. More books are in preparation dealing with land and water management practices and a collection of Dreaming stories.

The dissertation is organized in 3 chapters dealing with the timescale of macrodynamic growth models in the short and in the long run, as well as with the analysis of the climate-economy interplay over the business cycle. The first essay provides an analytical solution to the differential equation that regulates the motion of the neo-Kaleckian model in the short run. After presenting a simple open economy neo-Kaleckian model with government activity, the essay analytically derives an expression for the time of adjustment, defined as the time required for the system to make a $ k $ percent adjustment from one steady-state to another. The second chapter seeks to answer the question of \textit{when is the long run} in long-run growth models driven by demand. By making use of numerical integration, the essay analyses the time of adjustment from one steady-state to the other in two well-known demand-led growth models: the Sraffian Supermultiplier and the fully-adjusted version of the neo-Kaleckian model. The third chapter of the dissertation presents a business cycle model encompassing the short-run effect of mobilizing green investment to achieve longer-term climate goals. In doing so, the chapter focuses on the dynamics of green and brown investment, assessing whether the interplay between green and capital formation, on one hand, and CO2 emissions, on the other, may allow for conditions of coupling or decoupling - speeding up or slowing down the path towards net-zero emissions.

Dawkins (1990) expressed that increasing service quality has been the most important key to success and survival in nowadays-competitive environments. Since 1980’s, management started to emphasize developing service tactics. Providing the service quality as customer’s expected. As high-consumerism, their demands are variety. Therefore, many organizations begin to launch different kinds of methods of management to improve service quality. Deshpande, Farley & Webster (1993) said, “Satisfying customer with positive thinking of service quality could keep them with organization and bring in high profits. ”Hence, studying in knowing the element of service quality particulate signification. Meanwhile, more and more companies are service quality-oriented. According to relationship reference, organizational climate has positive relationship with service quality. However, there are no specific research identify how and what kind of element affects service quality through organizational climate. In this research, we will figure out the relationship between organizational climate and service quality, base on the aspects of worker’s displayed positive emotions and job satisfaction. To verify if these two elements have mediating effect between organizational climate and service quality.

Climate change impacts on snow storages and spring runoff in the Vydra river basin Abstract As a result of increasing air temperature, the fraction of precipitation falling as snow decreases. This affects snow cover indicators including snow cover duration, snow cover extent and the amount of water that accumulates in snow cover during winter. These changes further propagate through local runoff process and alter winter and spring runoff. The impacts of air temperature warming of 1℃, 2℃ and 3℃ on the above-mentioned indicators were simulated using a conceptual catchment runoff model HBV-light. Multi- criteria calibration, based on functions describing the goodness of fit of simulated runoff and snow water equivalent (SWE) values was performed. The temperature change scenarios were derived using the delta-change method from reference dataset 1980-2014. The indicator changes were evaluated for 5 elevation belts of the catchment as well as for the catchment as a whole, so that the observed alternations of snow cover indicators could be related to the modelled alternations of runoff. The changes in snow cover characteristics based on these simulations include a decrease of snowfall fraction, shortened snow season, decrease in average and maximal SWE values, and the shift of the average day of year of SWEmax to...

L’analisi del fattore ventilativo riveste un ruolo interessante per la comprensione delle condizioni di comfort dello spazio urbano. Partendo dalla porosità dell’organismo architettonico, si è voluto incentrare l’attenzione su potenzialità e limiti della ventilazione naturale, analizzandone con occhio critico possibili ricadute progettuali in relazione ad uno specifico campo di indagine: la città storica. Proprio in questi brani di città, che oggi risultano essere quelli maggiormente vulnerabili dal punto di vista climatico, si deve parlare di ventilazione e di sfruttamento delle potenzialità di raffrescamento, lavorando in equilibrio quasi statico tra l’invarianza di un tessuto da tutelare e le possibili libertà progettabili. Dalla rilettura critica di conoscenze già acquisite all’esperienza sul campo, il lavoro di ricerca propone una calibrazione ed integrazione di metodi e strumenti operativi per una sistematizzazione metodologica ed operativa sul tema della ventilazione in questo specifico ambito urbano in vista di una possibile azione progettuale. Non linee guida, ma uno strumento speditivo di supporto nelle prime fasi di analisi e valutazione dell’intervento, capace di fornire una immediata verifica pratica degli assunti teorici, che si dimostri iterabile (ripetibile con facilità su realtà differenti), implementabile nel tempo e soprattutto flessibile (adattabile all’eterogeneità del reale).The analysis of the wind factor plays an interesting role in under-standing the comfort conditions of urban space. Starting from the porosity of the architectural organism, it was decided to focus attention on the potential and limits of natural ventilation, analyzing with a critical eye possible design effects in relation to a specific field of investigation: the historical city. Precisely in these parts of cities, which today are the most vulnerable from a climatic point of view, we must talk about ventilation and exploitation of the cooling potential, working in an almost static balance between the invariance of a fabric to be protected and the possible designable freedoms. From the critical reinterpretation of already acquired knowledge to the field experience, the research work proposes a calibration and integration of methods and operational tools for a methodological and operative systematization on the theme of ventilation in this specific urban area aiming to a possible design action. Not guidelines, but a supporting instrument in the early stages of analysis and evaluation of the intervention, able to provide an immediate practical verification of theoretical assumptions, which proves to be iterable (easily repeatable on different realities), implementable over time and above all flexible (adaptable to the heterogeneity of reality).

In connessione con i recenti orientamenti della storiografia internazionale, sempre più attenti al nesso scienza-imperialismo, questo lavoro prende in esame i meccanismi di formazione, nell’Italia liberale e durante il regime fascista, della conoscenza medica sulle malattie tropicali: un settore del sapere medico sviluppatosi a fine ottocento sulla base delle proposte teoriche di Patrick Manson, sollecitato dalle scoperte della batteriologia di Louis Pasteur e Robert Koch e dagli avanzamenti della parassitologia. L’intento del lavoro è indagare le connessioni che intercorrono tra le esigenze di governo dei territori d’oltremare e lo strutturarsi di questo nuovo settore del sapere medico, non solo delineando i poli di sviluppo della disciplina, le reti (locali e globali) che hanno contribuito alla loro formazione, ma mettendo in evidenza l’effetto di riconfigurazione dello spazio (“scientifico”, geografico) che la nozione di “tropicale”, fatta propria dalla medicina di fine XIX sec., porta con sé. Attraverso l’esame dei caratteri della sanità bellica delle campagne di conquista coloniali - in particolare del conflitto italo-turco e della guerra d’Etiopia - lo studio si interroga sulla relazione fra dimensione strutturale e forme congiunturali di sviluppo dei saperi medici, collocando le trasformazioni conosciute dalla sanità di guerra in colonia nel più ampio quadro dei processi di modernizzazione e specializzazione dell’istituzione militare, senza dimenticare gli effetti di discontinuità introdotti nella pratica medica dalla Grande Guerra. Guardando alla scienza come luogo di sedimentazione, oltreché di produzione, di idee e stereotipi razziali, e prestando attenzione alle dinamiche di circolazione dei saperi, il lavoro prende infine in esame le rappresentazioni che la letteratura medica offre sulla fisiologia e sui meccanismi funzionali dell’organismo ai “tropici” (quello del colono e quello del colonizzato), facendo emergere come la relazione tra organismo e ambiente - cioè tra europeo e il nuovo spazio di conquista e tra "indigeno" e il proprio ambiente di vita - costituisca un nodo simbolico attorno a cui si addensano le concezioni con cui la medicina si troverà ad affrontare il problema della diversità del vivente. A preoccupare i medici sia in età liberale, come in epoca fascista, è infatti la questione dell' "acclimatazione", dell’adattamento cioè del bianco al nuovo ambiente tropicale: un tema che offre ai clinici un vero e proprio strumento di lettura degli stati patologici dell’organismo al tempo dell’espansione coloniale otto-novecentesca; non l’organismo “statico” - anatomico, dell’anatomia comparata - ma l’organismo fisiologico, “in trasformazione” nello spazio ridisegnato dall’imperialismo europeo.

Full textAbstract:
Invitato a Costantinopoli da una delegazione nicena, che ne chiedeva l’intervento a sostegno della comunità ortodossa locale, Gregorio di Nazianzo accantonò il desiderio di dedicarsi alla vita contemplativa e si recò nella Neja ÔRwvmh: non poteva certo immaginare che negli anni trascorsi nella capitale (dagli inizi del 379 al luglio del 381) avrebbe conosciuto, a distanza di breve tempo, l’apice e il fallimento della sua attività politico-ecclestiastica. Alla guida di un piccolo gruppo di fedeli, radunati in una sala udienze privata ribattezzata Anastasia, Gregorio esercitò con impegno i suoi doveri pastorali, spendendosi soprattutto nella lotta dottrinale contro l’eresia ariana. L’elezione come vescovo della città, avvenuta per volere dell’imperatore Teodosio, rappresentò il riconoscimento dei meriti del Cappadoce nella restaurazione e nel consolidamento dell’ortodossia nicena, ma, allo stesso tempo, aprì la strada a una stagione tutt’altro che scevra di asprezze, destinata a lasciare amari ricordi nel cuore dell’autore. Chiamato a presiedere il concilio episcopale del 381, indetto con l’obiettivo di risolvere lo scisma antiocheno e condannare le eresie del tempo, il Nazianzeno sperimentò sulla propria i conflitti interni ed i giochi di potere cui si era ridotto l’episcopato. Alla malattia, che debilitò il fisico dell’autore e ne ostacolò la partecipazione a svariate attività pubbliche, si aggiunse l’ostilità dei colleghi, in particolare di alcuni vescovi egiziani, che contestarono la legittimità della sua elezione sul seggio di Costantinopoli, in quanto già vescovo nella sede di Sasima. Stanco e malato, amareggiato dai continui scontri e dall’ennesimo attacco subito dagli avversari, Gregorio decise di farsi da parte e, rassegnate le dimissioni dalla cattedra episcopale, lasciò Costantinopoli, senza neppure aspettare la conclusione del sinodo. Nella natia Cappadocia, lontano fisicamente dal clima tumultuoso e dai dispiaceri della capitale, ma turbato dalle calunnie e dalle ingiustizie subite da coloro che riteneva amici, il Nazianzeno sfogò le proprie delusioni nella scrittura poetica. All’esperienza costantinopolitana e in particolare al contesto delle dimissioni dalla cattedra vescovile fanno riferimento i carmi oggetto di questa tesi di dottorato: II,1,10 (Ai sacerdoti di Costantinopoli e alla città stessa) e II,1,13 (Ai vescovi), rispettivamente di 18 distici elegiaci e 217 esametri. In essi si intrecciano più suggestioni: la meditazione e il riecheggiamento interiore degli eventi che hanno coinvolto l’autore, la difesa del suo operato, ma soprattutto la violenta invettiva contro i vescovi, scaturita non solo dal risentimento per le vicende personali, ma dallo sdegno dell’autore per la corruzione morale e l’impreparazione della gerarchia ecclesiastica. La tesi di dottorato si apre con una bibliografia ricca e aggiornata degli studi concernenti il Cappadoce; in essa sono indicati i diversi contributi, cui si fa riferimento nel mio lavoro. Segue un’ampia introduzione che presenta i carmi sotto molteplici aspetti. Dal momento che l’invettiva contro i vescovi costituisce l’argomento principale di entrambi i
componimenti, ho approfondito innanzitutto questo aspetto, ripercorrendone le testimonianze nell’esperienza biografica e nell’opera letteraria dell’autore: da quanto emerso, la polemica contro la gerarchia ecclesiastica raggiunge certamente il suo apice negli eventi costantinopolitani, ma non va ad essi circoscritta, dal momento che se ne ha traccia anche negli scritti gregoriani riconducibili ai primi anni del sacerdozio e al periodo successivo al ritorno a Nazianzo. Si è cercato poi di stabilire la data di composizione dei carmi in analisi, che, dati i contenuti, furono sicuramente scritti dall’autore nel periodo di ritorno in patria, fase in cui gli studiosi collocano buona parte della produzione poetica del Cappadoce. Più precisamente ho individuato il terminus post quem nel luglio del 381, mese in cui la cattedra costantinopolitana lasciata vacante dal Nazianzeno fu affidata a Nettario: in entrambi i testi, infatti, si fa riferimento a questo personaggio, sebbene non sia menzionato esplicitamente. Segue un’analisi dettagliata della struttura compositiva e delle tematiche dei carmi, nella quale si mostra come, pur nella loro diversità, le due poesie presentino moltissime consonanze e parallelismi a livello strutturale, in particolare nella parte incipitaria, in cui si registra la condivisione dello stesso verso iniziale, e nella sezione conclusiva. Sempre nell’introduzione è affrontato lo studio della tradizione manoscritta e dei rapporti tra i codici: i carmi in oggetto risultano attestati in 34 manoscritti (di cui 17 fondamentali per la costituzione del testo) databili dall’XI al XVI secolo e riconducibili alle raccolte antiche Σ e Δ, nei quali sono traditi sempre uno di seguito all’altro: nello specifico II,1,13 precede immediatamente II,1,10. La parte centrale della tesi è costituita dal testo critico di ciascun carme, seguito da traduzione e commento. La tesi costituisce il primo lavoro di questo tipo per il carme II,1,13; II,1,10 è stato invece oggetto di studio di due recenti edizioni: quella dei primi undici poemata de seipso del Nazianzeno curata da Tuilier - Bady - Bernardi per LesBL ed edita nel 2004 e un’edizione commentata di Simelidis, pubblicata nel 2009. Suddetti lavori non hanno rappresentato un ostacolo al progetto. Nessuno di essi infatti ha previsto lo studio simultaneo dei due testi poetici, che, a mio giudizio, non possono essere compresi a fondo se svincolati l’uno dall’altro; non sono risultati immuni da pecche sotto il profilo della critica testuale; il commento è assente nell’edizione francese, scarno e non sempre condivisibile in quella del Simelidis. La tesi è infine corredata da tre appendici che permettono di seguire la fortuna dei componimenti poetici. La prima di esse è dedicata al Commentario di Cosma di Gerusalemme ai Carmi del Nazianzeno, collocato tra la fine del VII e inizio l’VIII secolo. Il commentario, tradito da un unico manoscritto, il Vaticanus graecus 1260 del XII secolo, ha visto la sua editio princeps nel 1839 a cura del cardinale Angelo Mai nel secondo volume del suo Spicilegium Romanum, ristampata con lievi modifiche nel volume 38 della Patrologia Graeca. Una più recente edizione è stata curata da Lozza nel 2000. Nell’opera di Cosma vengono analizzati trentaquattro versi di carme II,1,13 e due di carme II,1,10; l’ampiezza delle citazioni va da un minimo di un verso a un massimo
di 5. Segue un’appendice dedicata alle parafrasi bizantine, che in alcuni manoscritti contenenti i carmi, accompagnano il testo poetico. Tali spiegazioni in prosa, composte in un momento non precisabile della trasmissione dell’opera gregoriana, sono anonime, di diverso livello letterario e da intendere come un testo in continua evoluzione, oggetto di modifiche da parte di ciascun copista. Nel caso dei testi in oggetto le parafrasi trasmesse sono tre, chiamate, sulla scia di studi precedenti, Paraphr. 1, Paraphr. 2, Paraphr. 3 e delle quali la tesi fornisce l’editio princeps. L’ultima appendice è costituita dalla traduzione latina dei carmi di Giacomo Oliva da Cremona, redatta nella seconda metà del XVI secolo per incarico del Cardinal Guglielmo Sirleto e testimonianza del grande interesse per il Cappadoce in questo periodo storico. Il lavoro dell’Oliva, rimasta inedito per la morte del committente e probabilmente anche per il suo scarso valore letterario, è trasmesso da due manoscritti autografi, il Vaticanus Barberinianus lat. 636 (B) e il Vaticanus lat. 6170 (V) e trova nella tesi la sua editio princeps.
